Description

General vehicle anti-theft alarm device

Technical Field

The utility model relates to the technical field of burglar alarms of electric bicycles, and particularly provides a universal vehicle burglar alarm device.

Background

The burglar alarm system of the electric two-wheeled vehicle mainly comprises a motor controller used for controlling a motor to work, a PKE burglar alarm used for vehicle antitheft control, an induction key, a key starting key used for starting the vehicle, a P-gear key (namely a parking gear of the motor controller) connected to the motor controller, a cushion lock capable of being opened in a mechanical and electronic mode and a cushion lock key connected to the cushion lock, wherein the PKE burglar alarm has a keyless entry function, namely when the induction key is close to the vehicle, the PKE burglar alarm can automatically prevent (remove the antitheft function), and when the induction key is far away from the vehicle, the PKE burglar alarm can automatically set up the protection (set the antitheft function). And when the PKE burglar alarm is in defense, if a vehicle shakes or wheels are pushed, the PKE burglar alarm can send a motor locking signal to the motor controller, so that the motor controller locks the motor and sends out an alarm sound. When the PKE burglar alarm is in a defense release state, a user can start the vehicle (namely, the vehicle is powered on) by pressing the one-key starting key, the P gear can be released by pressing the P gear key after the vehicle is started, and the vehicle enters a normal running state. In addition, when the PKE burglar alarm is unlocked, a user can open the seat cushion lock by pressing the seat cushion lock key.

At present, the traditional PKE burglar alarm needs a connector of 6 pins +4 pins to be implemented, and the above 10 pins are respectively: pin 1: GND power negative interface, pin 2: LD round-robin signal interface, pin 3: SPEED overspeed signal interface, pin 4: SDJ lock motor signal interface, pin 5: ACC electric gate signal interface, pin 6: BAT power supply positive interface, pin 7: KEY one KEY actuation KEY, pin 8: ZDS cushion lock, pin 9: empty, pin 10: and (4) empty feet. However, because the existing electric two-wheeled vehicles with large inventory and large shipment on the market generally adopt 6pin interfaces (without additional 4pin interfaces), if the traditional PKE alarm is used, a wire harness and an interface are required to be added for coping, so that each vehicle type and each vehicle need to be designed and changed, or a circuit needs to be modified to use the traditional PKE burglar alarm, the investment is high, the workload is large, and the development of the vehicle is limited.

In view of the above, the present invention is particularly proposed.

Further preferably, the first transistor Q1 and the fourth transistor Q4 both use PNP transistors; the second triode Q2, the third triode Q3, the fifth triode Q5 and the sixth triode Q6 all adopt NPN triodes.

In addition, the utility model also provides a working principle of the vehicle anti-theft alarm device, which specifically comprises the following steps:

1. when the PKE burglar alarm is armed, the first contact (point A) is defaulted to no level signal. When the key is close to the vehicle but no level signal is generated at the first contact, the MCU controller 2 firstly controls the second transistor Q2 and the first transistor Q1 to be sequentially turned on to raise the level at the first contact, and the third transistor Q3 can be turned on as the level at the first contact is raised, and then the start button 11 is pressed, so that the MCU controller 2 can detect the level change and further detect the motion of the start button 11, and the MCU controller 2 defaults that the motion of the start button 11 at this time represents a "one-key start" signal, and accordingly controls the vehicle to be powered on;

when the vehicle is powered on, the MCU controller 2 controls the second triode Q2 and the first triode Q1 to be closed, at the moment, the starting key 11 is pressed again, so that the P gear can be released (namely, the starting key 11 integrates the functions of 'one-key starting' and 'P gear'), then the motor controller controls the motor to operate according to the detected 'P gear releasing signal', and the vehicle enters a normal driving state; description of the drawings: when the start key 11 is pressed down and the P range is released, the third triode Q3 is in a closed state, and the MCU controller 2 ignores the "release P range signal" because the motor is not operating normally, which can be ignored;

when the vehicle enters a normal driving state, if the signal transmitted through the overspeed signal cable 10 is a high-level signal, the third transistor Q3 is turned on, the MCU controller 2 detects the signal and determines that the vehicle is not speeding, and if the signal transmitted through the overspeed signal cable 10 is a low-level signal, the third transistor Q3 is not turned on and is in a turned-off state, and the MCU controller 2 does not detect the signal and determines that the vehicle is speeding.

2. When the PKE burglar alarm is armed, the second contact (point B) is defaulted to no level signal. In a defense state, after the PKE burglar alarm enters an alarm state, the PKE burglar alarm controls the motor controller to be powered on, the motor controller pulls up the level at the second contact point (because the motor controller is connected with the second contact point through a cable), and the level at the second contact point is pulled up, so that the sixth triode Q6 is opened, the output end of the MCU controller 2 is communicated with the motor locking signal cable 12, and then a "motor locking signal" is sent to the motor controller;

in addition, according to the above, when the key approaches the vehicle but there is no level signal at the first contact, the MCU controller 2 controls the second transistor Q2 and the first transistor Q1 to turn on in sequence, so as to raise the level at the first contact, that is, the third transistor Q3 is turned on, and at this time, the start button 11 is pressed in double, the MCU controller 2 may detect the operation of the start button 11, and control the fifth transistor Q5 and the fourth transistor Q4 to turn on in sequence, so as to raise the level at the second contact, so that the seat cushion lock 13 is turned on. In addition, when the level at the second node is pulled high, the sixth transistor Q6 may be turned on, but the MCU controller 2 ignores this high signal.

In conclusion, the overspeed signal cable and the starting button are integrated together, and the motor locking signal cable and the seat cushion lock are integrated together through the improvement of the circuit structure, so that the installation steps between a product and other devices are simplified on the basis of ensuring the realization of all functions of the traditional PKE burglar alarm, and the product is more convenient to install; and the universal matching of the product is greatly improved, so that the product has better market competitiveness.
