Description

  The present invention relates to an anti-theft device. Specifically, it is light and compact, and an auxiliary anti-theft device that is easy to retrofit without complicating the electric control configuration, and a light and compact auxiliary anti-theft device that is excellent in fuel efficiency, turning operation, and rough road performance. It is related to the vehicle with attached.

  Conventionally, in vehicles such as motorcycles and passenger cars (hereinafter simply referred to as “vehicles”), if various sensors such as an acceleration sensor detect vibrations, tilts, and movements of a vehicle in a parked vehicle, 2. Description of the Related Art An anti-theft device is known that notifies the surroundings of the occurrence of an abnormal situation such as theft of a vehicle or its component parts by performing an anti-theft operation such as generating an alarm sound such as an alarm or a siren.

  Such an anti-theft device usually operates with electric power from a vehicle battery for driving the vehicle. For this reason, if the vehicle battery itself has been removed in advance, or if the electric cable from the vehicle battery to the anti-theft device has been cut, the power supply to the anti-theft device has already stopped even if the vehicle body moves. As a result, the above-described anti-theft operation is not performed.

  In recent years, theft using such an anti-theft device has frequently occurred, especially in motorcycles where access to the battery from the outside is easier compared to passenger cars. There is a strong demand for technology that reliably prevents this.

  In contrast to this, by providing a separate auxiliary battery that can supply power to the anti-theft device in addition to the vehicle battery, the power supply voltage of the vehicle battery can be reduced by removing the vehicle battery or disconnecting the power supply wires. There is a known technique for automatically switching the power supply to the anti-theft device from the vehicle battery so far to the auxiliary battery and maintaining and controlling the anti-theft operation when the power supply is lowered or the power supply is interrupted (for example, Patent Documents). 1).

  The anti-theft device comprises a plurality of anti-theft devices comprising a first anti-theft device and a second anti-theft device, a communication means is provided between the anti-theft devices, and an operation signal of one anti-theft device is sent to the other anti-theft device. A technique for operating the other antitheft device by enabling transmission to the prevention device is also known (see, for example, Patent Document 2).

  Using the technique of this Patent Document 2, preliminary operation that is indispensable before the vehicle battery is removed or the power supply wire is disconnected, for example, operation such as battery cover removal (hereinafter referred to as “theft preliminary operation”). ) Is detected at an early stage by one antitheft device, and an operation signal associated with the detection is transmitted to the other antitheft device to perform the antitheft operation, thereby preventing theft by invalidating the antitheft device. Such a response is conceivable.

  However, in the anti-theft device described in Patent Document 1, it is necessary to mount two batteries, a vehicle battery and a spare battery, which are heavy and large devices. For this reason, in a vehicle such as a motorcycle in which the installation space of the device is limited, not only the weight of the vehicle body but also the increase in size cannot be avoided, and the fuel consumption decreases, the turning operation, and the rough road running performance deteriorate.

  Furthermore, the power supply switching control device for monitoring the power supply voltage of the vehicle battery and automatically switching the power supply from the vehicle battery to the auxiliary battery when the power supply voltage drops or the power supply is interrupted is Since close electrical control linkage is required, it is actually necessary to incorporate it in advance from the design stage. This complicates the power supply control configuration and increases the cost of the control device. It is difficult to add power supply switching control as a retrofit, and it is difficult to apply it to already commercialized vehicle types.

  Further, in the anti-theft device described in Patent Document 2, since the operation signal of one anti-theft device is transmitted to the other anti-theft device via a predetermined communication means, the anti-theft device is also closely connected between both anti-theft devices. Cooperation in electrical control is required. Therefore, to add another anti-theft device (hereinafter referred to as “auxiliary anti-theft device”) to the anti-theft device (hereinafter referred to as “basic anti-theft device”) that performs the main anti-theft operation in the vehicle, In practice, it is necessary to incorporate a communication control structure for communication between the two devices in advance from the design stage, or to add an expensive communication device with excellent versatility. For this reason, the communication control configuration is expensive and complicated, and as with the technique of Patent Document 1, the cost of the control device increases, and it is difficult to add an auxiliary anti-theft device retrofitting and has already been commercialized. It is difficult to apply to existing car models.

  The present invention was devised in view of the above points, and it is light and compact, and an auxiliary anti-theft device that is easy to be retrofitted without complicating the electric control configuration, and light and compact, fuel efficiency, An object of the present invention is to provide a vehicle with an auxiliary anti-theft device excellent in turning operation and rough road running.

  In order to achieve the above object, the auxiliary anti-theft device of the present invention provides an anti-theft operation for receiving vibration from a vehicle battery that drives the vehicle against a basic anti-theft device that performs an anti-theft operation in a vehicle. A signal generator that transmits as a start signal of the vehicle, an auxiliary sensor unit that detects a detachment operation for detaching a vehicle component constituting the vehicle, and an auxiliary unit from the vehicle battery to the signal generator based on the detection result of the auxiliary sensor unit And a sensor switch having a switch part for opening and closing the power feeding path.

  The anti-theft device is controlled by a signal generator that transmits, as a start signal for the anti-theft operation, vibration generated by receiving power from the vehicle battery that drives the vehicle to the basic anti-theft device that performs the anti-theft operation in the vehicle. The cost of the apparatus is reduced and the number of applicable models can be expanded. That is, since vibration becomes a start signal for the anti-theft operation, close electrical control linkage between multiple devices is not required, and a simple electrical control configuration is required, and additional devices are incorporated in advance from the design stage. No need to add expensive equipment with excellent versatility, or simply add auxiliary anti-theft devices by adding simple components and wiring. It can be easily applied to commercialized vehicle types, and can be retrofitted by the user himself.

  Furthermore, it has an auxiliary sensor unit that detects a detaching operation for detaching a vehicle component that constitutes the vehicle, and a switch unit that opens and closes an auxiliary power supply path from the vehicle battery to the signal generator based on the detection result of the auxiliary sensor unit. The sensor switch can improve fuel consumption, turning operation, and rough road running performance. In other words, as a component device other than the signal generator, it is only necessary to provide a sensor switch that is lighter and smaller in size than the spare battery, so even in a vehicle where the installation space of the device is limited, such as a motorcycle. Even if it exists, the weight increase and enlargement of a vehicle body can be prevented.

  In addition, the basic power supply path from the vehicle battery to the basic anti-theft device is connected to the vehicle battery side from the switch part in the auxiliary power supply path by a predetermined locking operation, and the connection from the vehicle battery to the switch part is conducted. If there is an energization switch to be operated, when a lock operation such as a handle lock by a key cylinder is performed, the energization switch is turned on and power is supplied to the basic antitheft device (hereinafter referred to as “standby state”). At the same time, the power is supplied to the switch unit, and the auxiliary antitheft device can be shifted to the standby state. In this standby state, when the auxiliary sensor unit detects the detachment operation of the vehicle component, the switch unit is closed and all the auxiliary power supply paths from the vehicle battery to the signal generator are connected, and power is supplied to the signal generator. Is set to generate an auxiliary alarm sound. This eliminates the need for separate standby operations for the basic anti-theft device and the auxiliary anti-theft device, thereby significantly improving the operability of the anti-theft device.

  Also, if the vibration is an alarm sound as air vibration, if the alarm sound is generated from the signal generator when the auxiliary anti-theft device detects theft, this alarm sound synergizes with the alarm sound generated from the basic anti-theft device. In addition, since it reverberates widely, the anti-theft effect is greatly improved. Furthermore, even if the basic anti-theft device is unstable due to deterioration of the constituent devices over time and does not perform the anti-theft operation, an alarm sound can be generated only by the auxiliary anti-theft device. It is possible to reliably exhibit the notification function.

  In addition, when the signal generator is placed in a closed space surrounded by an exterior member of the vehicle, together with a basic sensor unit that can detect an alarm sound emitted by the signal generator in the basic anti-theft device, The alarm sound emitted from the generator can be reflected by the inner wall surface of the exterior member in the closed space. As a result, the reflected wave reflected by the inner wall surface of the exterior member can be superimposed on the direct wave directly transmitted from the signal generator to the basic sensor unit, and the input energy of the alarm sound received by the basic sensor unit can be increased. It is possible to increase the sensitivity of the sensor and shorten the response time until the anti-theft operation is performed.

  In addition, the signal generator is configured such that the output portion of the alarm sound is opposed to the inner wall surface of the exterior member, and the central axis of the sound beam of the alarm sound directly output from the output portion is the center of the sound beam. If it has a tilting structure that tilts toward the basic sensor part from the vertical line that hangs on the inner wall surface of the exterior member from the point, the alarm sound emitted from the signal generator will not scatter to the opposite side of the basic sensor part Can be. As a result, the energy of the reflected wave of the alarm sound can be concentrated on the basic sensor unit, and the sensor energy can be further increased by further increasing the input energy of the alarm sound received by the basic sensor unit until the anti-theft operation is performed. The response time can be further shortened.

  Also, when the basic sensor unit is placed on a common plane that passes through the central axis and perpendicular, the high-energy-density part of the sound wave of the alarm sound emitted from the signal generator is concentrated on the basic sensor unit as a reflected wave. Can be made. As a result, the energy of the reflected wave of the alarm sound can be concentrated on the basic sensor unit, and the response time until the anti-theft operation is performed by further increasing the input energy of the alarm sound received by the basic sensor unit is further reduced. Can be achieved.

  Further, when the sensor switch has a movable body that detects the detaching operation of the vehicle component by moving in the same direction as the detaching direction of the vehicle component, the operation amount of the detaching operation of the vehicle component is small. Also, it is possible to secure a sufficient amount of movement of the movable body. Thereby, the sensitivity of the sensor for detecting the detachment operation can be increased, and the response time until the alarm sound is generated by the auxiliary anti-theft device and the anti-theft operation by the basic anti-theft device can be shortened.

  In addition, when the vehicle component is a battery cover that is attached to a recess that houses a vehicle battery and closes the opening end of the recess, the vehicle and its components can be detected only by detecting the attachment / detachment of the battery cover with the auxiliary antitheft device. It is possible to reliably grasp that an operation of removing the vehicle battery or disconnecting the electric power supply wire is about to be performed. As a result, it is not necessary to provide sensor switches for all components that are likely to be stolen, and it is possible to reduce component costs and improve maintainability.

  Further, when the sensor switch is disposed in the vicinity of the attachment portion for attaching the battery cover to the recess, the portion near the attachment portion is moved by the battery cover at a very initial stage of the battery cover detachment process. As a result, the detection time until the battery cover detachment operation is detected is shortened, and as a result, the response time until the anti-theft operation is performed can be shortened.

  Further, the sensor switch moves in a direction substantially different from the direction in which the battery cover is attached / detached, thereby moving in a direction different from the direction in which the battery cover is attached / detached, and the first sensor switch including the first movable body that detects the attachment / detachment operation. Thus, when it has at least one second sensor switch including the second movable body that detects the detachment operation, the detachment operation of the battery cover in a plurality of directions can be detected. Thereby, even if the removal | desorption direction of a removal | desorption operation | movement differs from usual, it can detect reliably and can raise the sensor sensitivity of a sensor switch.

  When the basic power supply path and the auxiliary power supply path are arranged in the vehicle interior space surrounded by the structural wall that forms the recess and the exterior wall on the opposite side of the structural wall, the basic power supply path and the auxiliary power supply path It is possible to make it difficult to access the wires in the middle from the outside. This makes it difficult to disconnect from the outside to the middle part of the electric wire, prevents invalidation of the basic anti-theft device and auxiliary anti-theft device, and removes the battery cover. Desorption can be positively detected by the sensor switch.

  In order to achieve the above object, a vehicle with an auxiliary antitheft device according to the present invention generates vibration generated by receiving power from a vehicle battery that drives the vehicle, with respect to a basic antitheft device that performs an antitheft operation in the vehicle. A signal generator that transmits as a start signal of the anti-theft operation, an auxiliary sensor unit that detects an attaching / detaching operation for attaching / detaching vehicle components constituting the vehicle, and a signal generator from the vehicle battery based on the detection result of the auxiliary sensor unit And an auxiliary anti-theft device provided with a sensor switch having a switch part that opens and closes the auxiliary power supply path.

  The anti-theft device is controlled by a signal generator that transmits, as a start signal for the anti-theft operation, vibration generated by receiving power from the vehicle battery that drives the vehicle to the basic anti-theft device that performs the anti-theft operation in the vehicle. The cost of the apparatus is reduced and the number of applicable models can be expanded. That is, since vibration becomes a start signal for the anti-theft operation, close electrical control linkage between multiple devices is not required, and a simple electrical control configuration is required, and additional devices are incorporated in advance from the design stage. No need to add expensive equipment with excellent versatility, or simply add auxiliary anti-theft devices by adding simple components and wiring. It can be easily applied to commercialized vehicle types, and can be retrofitted by the user himself.

  Furthermore, it has an auxiliary sensor unit that detects a detaching operation for detaching a vehicle component that constitutes the vehicle, and a switch unit that opens and closes an auxiliary power supply path from the vehicle battery to the signal generator based on the detection result of the auxiliary sensor unit. The sensor switch can improve fuel consumption, turning operation, and rough road running performance. In other words, as a component device other than the signal generator, it is only necessary to provide a sensor switch that is lighter and smaller in size than the spare battery, so even in a vehicle where the installation space of the device is limited, such as a motorcycle. Even if it exists, the weight increase and enlargement of a vehicle body can be prevented.

  The auxiliary anti-theft device according to the present invention is light and compact, and the electric control configuration is not complicated and can be easily retrofitted. A vehicle equipped with the auxiliary anti-theft device is also light and compact. Therefore, it has excellent fuel economy, turning operation, and rough road performance.

  Further, the front part of the handle post 8 is covered with a front cover 15 opened rearward, and the rear part of the handle post 8 is covered with a front inner cover 16 opened forward, so that the front cover 15 and the front inner cover are covered. Of the basic anti-theft device 17 that is mounted in advance on the vehicle 1 to perform the anti-theft operation and the auxiliary anti-theft device 20 according to the present invention. The auxiliary alarm device 21 which is a signal generator is accommodated. In this embodiment, the auxiliary antitheft device 20 is retrofitted by the user. However, the auxiliary antitheft device 20 may be installed as a standard specification in the vehicle 1 together with the basic antitheft device 17. The wearing time of 20 is not particularly limited.

  In addition, the handle post 8 is provided with a handle lock device 28. When a key 30 is inserted into a key cylinder 29 constituting the handle lock device 28 and the key 30 is turned to a predetermined lock position, A lock pin (not shown) is engaged with the head pipe 4 so that the handle 9 is locked so that the handle 9 cannot be operated.

  The vehicle frame 3 is covered with a vehicle body cover 24 in the middle of the front and rear, and a driver seat 25 on which a driver and a passenger sit is placed above the vehicle body cover 24 via a hinge (not shown). It can be opened and closed freely. A substantially horizontal floor step 26 on which the driver and passengers put his / her feet rests is formed in the front portion of the vehicle body cover 24, and electric power is supplied to the cell motor for the engine 11 described later in the floor step 26. A vehicle battery 27 for driving the vehicle 1 is housed.

  In addition, a power unit 13 having an engine 11 and a power transmission unit 12 is supported at the rear part of the body frame 3 so as to be able to swing up and down, and the rear wheel 6 is held at the rear end of the power transmission unit 12, A rear cushion absorber 14 is interposed between the rear end of the power transmission unit 12 and the rear part of the vehicle body frame 3. When the key 30 is rotated to a predetermined starting position, a current is supplied from the vehicle battery 27 to the cell motor. Flows to start the engine 11 and the elastically supported rear wheel 6 is driven.

  Next, the structure of the basic antitheft device 17 and the auxiliary antitheft device 20 according to the present invention will be described with reference to FIGS.

  The basic anti-theft device 17 mounted on the vehicle 1 is mounted on the vehicle 1 as a standard specification and performs an anti-theft operation. An alarm such as a buzzer or a siren is received by receiving electric power from the vehicle battery 27 described above. A basic alarm device 18 capable of generating a sound (hereinafter referred to as “basic alarm sound”) 31, and when a vibration, inclination, movement, etc. of the vehicle body is detected, a current is passed through the basic alarm device 18 to generate a basic alarm sound 31. A sensor unit 19 and a basic power supply path 38 made of electric wires capable of supplying power from the vehicle battery 27 to the basic alarm device 18 via the sensor unit 19 are provided.

  Of these, the basic alarm device 18 uses a donut-shaped flat horn in the present embodiment. The basic alarm sound 31 is obtained by intermittently passing a current through an electromagnet coil and vibrating the diaphragm by the generated magnetic force. It may be a speaker that emits a warning sound, a warning light that blinks light, etc., and its type is particularly limited as long as it can notify the occurrence of an abnormal situation such as theft to the surroundings Is not to be done.

  The sensor unit 19 includes a basic sensor unit 33 having an acceleration sensor that can detect vibrations generated by the auxiliary alarm sound 32 emitted from the auxiliary alarm device 21 of the auxiliary antitheft device 20 in addition to the vibration, inclination, movement, etc. of the vehicle body described above. And a control unit 34 connected to the basic sensor unit 33 via a signal line 35.

  As a result, when the basic sensor unit 33 detects vibration, tilt, movement, or auxiliary alarm sound 32 of the vehicle body, an alarm signal 36 is transmitted from the basic sensor unit 33 through the signal line 35 to the control unit 34, and this control unit 34. As a result of the current control, the electric wires 38a and 38b before and after the sensor unit 19 are connected by the basic power supply path 38, and the electric power supplied to the sensor unit 19 is supplied to the basic alarm device 18 through the electric wires 38b. Thus, the basic alarm sound 31 can be generated.

  Further, the auxiliary anti-theft device 20 according to the present invention is a device that is attached to the vehicle 1 retrofitted to the vehicle 1 in this embodiment and emits an auxiliary alarm sound 32 as air vibrations. The auxiliary alarm sound 32 is received and this auxiliary alarm sound 32 is sent to the basic antitheft device 17 as a start signal for generating the basic alarm sound 31 that is the antitheft operation of the basic antitheft device 17. The above-mentioned auxiliary alarm device 21 for transmission, a sensor switch 22 for detecting an attachment / detachment operation for attaching / detaching vehicle components constituting the vehicle 1 and causing an electric current to flow through the auxiliary alarm device 21 to generate an auxiliary alarm sound 32, a vehicle battery 27 and an auxiliary power supply path 43 made of electric wires capable of supplying power from the switch 27 to the auxiliary alarm device 21. As described above, the auxiliary antitheft device 20 may be mounted on the vehicle 1 as a standard specification in the same manner as the basic antitheft device 17.

  In this embodiment, a flat horn is used for the auxiliary alarm device 21 as in the case of the basic alarm device 18 in this embodiment, and a current is intermittently passed through the internal coil, and the diaphragm is vibrated by the generated magnetic force. The auxiliary alarm sound 32 is emitted. However, unlike the basic alarm device 18 described above, the type of the auxiliary alarm device 21 needs to be detected by the basic sensor portion 33 of the basic anti-theft device 17 as a start signal for the anti-theft operation. However, a warning lamp or the like is excluded, but a warning lamp or the like is excluded.

  The sensor switch 22 is an auxiliary sensor unit 41 that detects the attachment / detachment operation of the battery cover 40 that covers the vehicle components constituting the vehicle 1, in this embodiment, the vehicle battery 27, and the auxiliary switch unit 41 based on the detection result of the auxiliary sensor unit 41. And a switch unit 42 that can open and close the power supply path 43.

  The auxiliary sensor unit 41 abuts on the object to be detected and can roll, and the roller 41a supports the roller 41a so that it can roll on the tip, and an arm 41b made of a long elastic member such as a stainless steel piece. And a link mechanism 41c that is connected to the circuit switch 42a in the switch unit 42 and transmits the rotation operation of the arm 41b.

  As a result, when the battery cover 40 is removed upward as indicated by an arrow 79, the roller 41a that is in contact with the lower surface 40a of the battery cover 40 by the elastic force of the arm 41b by the auxiliary sensor unit 41 in the biased state is While rolling on the lower surface 40 a, as shown by an arrow 73, the arm 41 b rotates around the base portion and rises.

  Then, the circuit switch 42a in the switch unit 42 is closed via the link mechanism 41c, and the electric wire 43a and the electric wire 43b before and after the switch unit 42 on the auxiliary power supply path 43 are connected, and the power supplied to the switch unit 42 is supplied. Is supplied to the auxiliary alarm device 21 through the electric wire 43b, and the auxiliary alarm sound 32 is generated. In this case, the moving direction of the roller 41a, that is, the upper direction in the present embodiment is set as the detection direction of the auxiliary antitheft device 20.

  That is, when the battery cover 40 is removed upward, the switch portion 42 of the auxiliary antitheft device 20 is closed, and electric power is supplied to the auxiliary alarm device 21 via the auxiliary power supply path 43 to generate the auxiliary alarm sound 32. Further, when the basic sensor unit 33 detects the vibration generated by the auxiliary alarm sound 32, electric power is supplied to the basic alarm device 18 through the basic power supply path 38 by the control unit 34, and the basic alarm sound 31 is generated. It becomes like this.

  With such a configuration, the auxiliary alarm sound 32 as air vibration can be used as a start signal for the anti-theft operation by the basic anti-theft device 17, and close electrical control linkage among a plurality of devices is not necessary. A simple electrical control configuration is sufficient. Further, it is not necessary to add an additional device in advance from the design stage or to add an expensive device having excellent versatility, and the simple sensor switch 22, the auxiliary alarm device 21, the electric wire 43a, and the electric wire 43b. Since it is possible to attach the auxiliary anti-theft device 20 simply by adding a new model, it can be easily applied to new models and already commercialized models, and can be retrofitted by the user as in this embodiment. It becomes.

  Further, as the constituent devices other than the auxiliary alarm device 21, it is only necessary to provide a sensor switch 22 that is lighter and smaller in size than the spare battery, so that the installation space of the device is limited as in a motorcycle. Even the vehicle 1 can prevent the vehicle body from being increased in weight and size.

  In addition, when the vibration is the auxiliary alarm sound 32 as air vibration as in the present embodiment, when the auxiliary anti-theft device 20 detects theft and the auxiliary alarm device 21 generates the auxiliary alarm sound 32, Since the auxiliary alarm sound 32 synergizes with the basic alarm sound 31 generated from the basic antitheft device 17 and reverberates widely, the antitheft effect is greatly improved. Further, even when the basic antitheft device 17 is unstable in operation due to deterioration of the constituent devices and does not perform the antitheft operation, the auxiliary alarm sound 32 can be generated only by the auxiliary antitheft device 20. Thus, the notification function of the anti-theft device can be surely exhibited.

  An energization switch 45 is provided in the middle of the common electric wire 37 of the basic power supply path 38 and the auxiliary power supply path 43 described above, in addition to a control unit that steps down the power from the vehicle battery 27 to a predetermined voltage of each device. Is provided.

  This energization switch 45 is provided in the above-described handle lock device 28, and in conjunction with the handle lock device 28 turning the key 30 to lock the handle, the energization switch 45 is closed, and the vehicle A basic power supply path 38 from the battery 27 to the basic antitheft device 17, specifically, the electric wires 37 and 38 a are made conductive.

  Further, since the energization switch 45 is on the common electric wire 37 in the auxiliary power supply path 43 and is disposed closer to the vehicle battery 27 than the switch unit 42 described above, the energization switch 45 is closed by locking the handle. Then, the auxiliary power supply path 43 from the vehicle battery 27 to the switch unit 42, specifically, the electric wires 37 and 43a are also conducted.

  In such a configuration, when a lock operation such as a handle lock is performed as described above, the energization switch 45 is automatically turned on to supply power to the sensor unit 19, and the basic antitheft device 17 detects the occurrence of an abnormal situation. In conjunction with the transition to a possible standby state, power is also supplied to the switch unit 42 of the auxiliary antitheft device 20, and the auxiliary antitheft device 20 can also be shifted to the standby state. In this standby state, when the auxiliary sensor unit 41 detects the attachment / detachment operation of the battery cover 40, the switch unit 42 is closed, and all the auxiliary power supply paths 43 from the vehicle battery 27 to the auxiliary alarm device 21 are connected. Driving power is supplied to the auxiliary alarm device 21 and an auxiliary alarm sound 32 is generated.

  For this reason, separate standby operations for the basic antitheft device 17 and the auxiliary antitheft device 20 become unnecessary, and the operability of the antitheft device can be remarkably improved.

  Next, the arrangement of the basic antitheft device 17 and the auxiliary alarm device 21 will be described with reference to FIGS.

  As shown in FIGS. 1 to 3, among the basic alarm device 18 and the sensor unit 19 constituting the basic antitheft device 17, the basic alarm device 18 is located on the right side of the inner wall surface 16 a on the front surface of the front inner cover 16 described above. On the upper part, the output part 18a of the basic alarm sound 31 is fastened and fixed by a bolt 49 in such a posture that it faces obliquely right frontward.

  The sensor unit 19 is fastened and fixed to the lower left portion of the inner wall surface 16 a of the front inner cover 16 by a bolt 50 in a posture in which a box-shaped unit case 19 a that forms the housing of the sensor unit 19 is substantially horizontal. And the basic sensor part 33 mentioned above is accommodated in this unit case 19a.

  The auxiliary alarm device 21 of the auxiliary antitheft device 20 is in a position such that the auxiliary alarm sound 32 is output substantially to the left at a position directly above the sensor unit 19 and below the basic alarm device 18. And the mounting plate 52 are fastened and fixed.

  The mounting plate 52 is formed by a mounting portion 52a that is bent in an L shape in plan view and extends rightward, and a support portion 52b that extends rearward from the left end of the mounting portion 52a and has a left side faced substantially to the left. The rear surface of the auxiliary alarm device 21 is fixed to the outer surface of the support portion 52b, and the bolt 51 is screwed into the attachment portion 52a from the front to be fastened and fixed to the substantially right and left center of the inner wall surface 16a. The auxiliary alarm device 21 is fastened and fixed to the inner wall surface 16a at the aforementioned position and posture.

  Here, as shown in FIGS. 3 and 4, the auxiliary alarm device 21 is a donut-shaped flat horn as described above, and includes a columnar electromagnet 55 in which a coil is connected to the electric wire 43 b of the auxiliary power supply path 43. A shaft 56 which is on the same axis 54 as the electromagnet 55 and vibrates on the axis 54 by the magnetic force of the electromagnet 55, a diaphragm 57 connected to the left end of the shaft 56, and an outer side of the diaphragm 57 A resonance plate 58 that resonates and amplifies the vibration generated by the collision between the electromagnet 55 and the shaft 56 is provided.

  The substantially central portion of the auxiliary alarm device 21 viewed from the resonance plate 58 side is an output portion 59 of the auxiliary alarm sound 32, and the auxiliary alarm sound 32 is an exterior member 53 from the output portion 59. The output is directed toward the inner wall surface 15 a of the front cover 15.

  As described above, the auxiliary alarm device 21 is surrounded by the exterior member 53 of the vehicle 1 together with the basic sensor unit 33 capable of detecting the auxiliary alarm sound 32 emitted from the auxiliary alarm device 21 in the basic antitheft device 17. By arranging in the closed space 23, the auxiliary alarm sound 32 emitted from the output portion 59 of the auxiliary alarm device 32 is caused to be transmitted to the inner wall surface of the exterior member 53 in the closed space 23, specifically, the inside of the front cover 15. The light can be reflected by the wall surface 15 a or the inner wall surface 16 a of the front inner cover 16.

  Then, in addition to the direct wave 60 directly transmitted from the auxiliary alarm device 21 to the basic sensor unit 33, a reflected wave 61 reflected by the inner wall surfaces 15 a and 16 a of the exterior member 53 is generated, and the reflected wave is reflected on the direct wave 60. 61 can be overlapped, the input energy of the auxiliary alarm sound 32 received by the basic sensor unit 33 is increased by adjusting the phase of both waves, etc., and the response time until the anti-theft operation is performed by increasing the sensor sensitivity is shortened. can do.

  As shown in FIG. 4, in the auxiliary alarm device 21, the direct wave 60 directly output from the output unit 59 spreads in a substantially conical shape, and the flow of the auxiliary alarm sound 32 (hereinafter referred to as “sonic wave beam”). ) 62 is formed, the central axis 63 of the sound beam 62 substantially coincides with the axis 54 described above.

  The output portion 59 is formed to face the inner wall surfaces 15a and 16a of the exterior member 53, and the central axis 63 of the sound beam 62 is the apex of the sound beam 62 (hereinafter referred to as “center point”). The auxiliary alarm device 21 has a tilting structure so that it tilts at an angle 66 toward the basic sensor part 33 side from a vertical line 65 suspended from the inner wall surfaces 15a, 16a of the exterior member 53.

  As a result, the auxiliary alarm sound 32 emitted from the auxiliary alarm device 21 does not scatter upward on the opposite side of the basic sensor unit 33 in this embodiment, and the energy of the reflected wave 61 of the auxiliary alarm sound 32 is changed to the basic sensor. It is possible to concentrate on the unit 33 and further increase the input energy of the auxiliary alarm sound 32 received by the basic sensor unit 33 to further increase the sensor sensitivity and to further shorten the response time until the anti-theft operation is performed. it can.

  Further, the basic sensor unit 33 that detects the auxiliary alarm sound 32 is disposed on a common plane 67 that passes through the above-described normal line 65 and the central axis 63.

  The common plane 67 indicates a plane through which the central axis 63 having the highest sound wave energy density and the reflected wave 61 pass in the sound wave beam 62, and thus the energy of the auxiliary warning sound 32 is on the common plane 67. As a result, the energy input to the basic sensor unit 33 increases.

  Thereby, the high energy density portion of the sound beam 62 of the auxiliary alarm sound 32 emitted from the auxiliary alarm device 21 can be concentrated on the basic sensor unit 33 as the reflected wave 61.

  Therefore, the energy of the reflected wave 61 of the auxiliary alarm sound 32 can be concentrated on the basic sensor unit 33 until the input energy of the auxiliary alarm sound 32 received by the basic sensor unit 33 is further increased to perform the anti-theft operation. The response time can be further shortened.

  Next, the arrangement configuration of the sensor switch 22 will be described with reference to FIGS. 1, 2, 5 to 8.

  As shown in FIGS. 1, 2, and 5, a box-like recess 68 having an open upper end is formed at the substantially center of the above-described substantially horizontal floor step 26 in plan view. And in this recessed part 68, while storing the vehicle battery 27, the sensor switch 22 is arrange | positioned.

Here, the closed configuration of the recess 68 will be described.
An opening end 68a of the recess 68 is formed in a stepped shape when viewed in cross section, and a substantially horizontal horizontal mounting surface 68a1 extending outward from the upper end of the inner wall 68c surrounding the periphery of the recess 68, and the horizontal mounting surface And a rising wall surface 68a2 standing from the outer end of 68a1. The above-described battery cover 40 has an outer peripheral edge 40d that has substantially the same shape as the rising wall surface 68a2, and is formed so that it can be inserted from above.

  A screw hole 68b into which a cover fixing screw 69 can be screwed is formed at the rear end portion of the horizontal placement surface 68a1. On the other hand, the opening end 68a is screwed when the opening end 68a is closed at the rear end portion 40f of the battery cover 40. A through hole 40c through which the cover fixing screw 69 can be inserted is formed at a position overlapping with the hole 68b.

  Further, a pair of left and right locking holes 68d are recessed in the front end side of the rising wall surface 68a2, while a pair of left and right locking holes 68d can be inserted into the locking hole 68d from behind and locked to the front end side of the battery cover 40. The locking piece 40e is projected.

  In such a configuration, when the battery cover 40 is mounted, the battery cover 40 is lowered from above into the opening end 68a, and the front cover is engaged with the posture in which the battery cover 40 is first inclined obliquely upward rearward. The stop piece 40e is raised and inserted into the locking hole 68d of the wall surface 68a2. Thereafter, the rear end portion 40f of the battery cover 40 is lowered around the locking piece 40e on the front end side, and the through hole 40c of the rear end portion 40f is overlapped with the screw hole 68b of the horizontal placement surface 68a1.

  At this time, since the outer peripheral edge 40d of the battery cover 40 has a guide structure that is placed close to the horizontal placement surface 68a1 while being slid on the rising wall surface 68a2 of the recess 68, the battery cover 40 is moved to the left and right. The opening end 68a can be quickly fitted into the opening 68 without shifting, and the workability of the closing operation of the opening end 68a of the recess 68 is improved.

  Then, with the through hole 40c overlapped with the screw hole 68b, the above-described cover fixing screw 69 is screwed into the screw hole 68b through the through hole 40c from above, so that the screw hole 68b is formed ( Hereinafter, the battery cover 40 is fastened and fixed to the “mounting portion” 70. Specifically, the battery cover 40 can be fixed to the opening end 68a by three points of the left and right engaging holes 68d on the front end side of the opening end 68a and the screw hole 68b on the rear end portion. So that it can be blocked.

  On the other hand, when the battery cover 40 is attached / detached, the cover fixing screw 69 is rotated and removed from the through hole 40c and the screw hole 68b, and then the battery cover 40 is moved around the locking piece 40e. The opening end 68a of the recess 68 is opened by pulling up the battery cover 40 while rotating the end portion 40f forward as indicated by an arrow 78.

  As described above, the sensor switch 22 is provided between the vehicle battery 27 and the inner wall 68c on the left side of the rear portion of the recess 68 covered with the battery cover 40, and is disposed in the vicinity of the mounting portion 70 described above. . The detection direction is substantially upward indicated by the arrow 73 as described above.

  Thus, when the battery cover 40 is removed upward, the auxiliary sensor unit 41 detects the attachment / detachment operation as described above and power is supplied to the auxiliary alarm device 21 to generate the auxiliary alarm sound 32. When the sensor switch 22 is in the vicinity of the mounting portion 70 as in the present embodiment, the auxiliary cover is almost simultaneously with the rear end portion 40f of the battery cover 40 being raised at the very initial stage of the battery cover 40 attachment / detachment process. The roller 41a of the sensor unit 41 is also raised. For this reason, the detection time until the removal / attachment operation of the battery cover 40 is detected is shortened, and as a result, the response time until the anti-theft operation is performed can be shortened.

  Furthermore, when the sensor switch 22 is provided in the battery cover 40 as described above, the vehicle battery 27 can be removed and the electric power can be removed in order to steal the vehicle 1 and its components only by detecting the attachment / detachment of the battery cover 40 with the auxiliary antitheft device 20. It is possible to reliably grasp that the work for disconnecting the supply electric wire is about to be performed. For this reason, it is not necessary to provide the sensor switch 22 for all the components that are likely to be stolen, and it is possible to reduce the cost of components and improve the maintainability.

Hereinafter, another embodiment of the sensor switch 22 will be described.

The second sensor switch 72 is provided in such a posture that the roller 72 a can move forward, and the detection direction is substantially forward indicated by an arrow 74. Specifically, the auxiliary sensor unit 41 and the switch unit 42 are arranged at the front and rear positions.

  In such a configuration, when the battery cover 40 is pulled upward as usual, the roller 71a of the first sensor switch 71 moves upward, the circuit switch 42a is closed, and the auxiliary alarm sound 32 is generated. Unlike the normal case, when the battery cover 40 is pulled out obliquely upward as indicated by an arrow 80, the roller 72a of the second sensor switch 72 moves forward, and the circuit switch 42a is similarly closed. An auxiliary alarm sound 32 is generated.

  As described above, the first sensor switch including the roller 71a that is the first movable body that detects the detachment operation by moving the sensor switch 22A substantially in the same direction as the detachment direction of the battery cover 40, in this embodiment. 71 and a second sensor switch 72 including a roller 72a which is a second movable body that detects a detachment operation by moving in a direction different from the detachment direction of the battery cover 40, in this embodiment, obliquely upward in the front direction. In the case where the battery cover 40 is provided, it is possible to detect the detaching operation of the battery cover 40 in two directions. Thereby, even if the removal | desorption direction of a removal | desorption operation | movement differs from usual, it can detect reliably and can raise the sensor sensitivity of 22 A of sensor switches.

  In the present embodiment, the second sensor switch 72 is single, but after providing a plurality of the second sensor switches 72, the movement directions of the rollers 72a are set to be different from each other. It can correspond to various attachment / detachment directions.

The roller 41 a is provided in such a posture that it can move forward, and the detection direction is substantially forward indicated by an arrow 75. Specifically, the auxiliary sensor unit 41 and the switch unit 42 are arranged in the front-rear position.

  Further, the front cover 15 covering the front opening of the front inner cover 16 is configured to be pulled forward when being detached from the front inner cover 16 and is substantially in the same direction as the detection direction of the sensor switch 22. Yes.

  As described above, the sensor switch 22B has the roller 41a that is a movable body that detects the attaching / detaching operation of the front cover 15 by moving in the substantially same direction as the front that is the attaching / detaching direction of the front cover 15 that is a vehicle component. In this case, even when the amount of movement of the front cover 15 is small, the amount of movement of the roller 41a can be sufficiently secured. Thereby, the sensor sensitivity for detecting the detachment operation can be increased, and the response time until the alarm sound is generated by the auxiliary antitheft device 20 and the antitheft operation by the basic antitheft device 17 is reduced. it can.
