Figure 1a is a perspective view schematically showing a vehicle accelerator pedal operating device of a general structure.

Referring to FIG. 1A, a vehicle acceleration pedal operating device 100 having a general structure may include a pedal arm 120, a rotation arm 130, and a carrier 160.

The pedal arm 120 is used to increase the speed of the vehicle by controlling the amount of fuel and air supplied to the engine engine by manipulating the driver's foot to speed up the rotation of the engine.

In addition, the pedal arm 120 has a pedal pad 110 connected to one end thereof so that the pedal pad 110 can be adjusted by stepping on the tip of the foot by the driver. Make an angular rotation around the bottom.

In addition, a rotation arm 130 is connected to one end of the opposite side of the pedal arm 120 connected to the pedal pad 110, and the rotation arm 130 may rotate around the hinge portion according to the movement of the pedal arm 120. And may be secured to a housing (not shown).

1A, an elastic member connected to the rotary arm 130 to provide a force in a direction opposite to the rotation of the rotary arm 130 is connected to the lower end of the rotary arm 130 of the vehicle accelerator pedal operating device having a general structure ( 150).

On the other hand, one end of the rotating arm 130 includes a carrier 160, the carrier 160 is applied to the driver by applying a force to the rotating arm 130, when the speed of the vehicle is more than a predetermined speed It can play a role in providing power.

In addition, the vehicle acceleration pedal operating device 100 of the general structure and the power transmission member 170 for transmitting a rotational force to the carrier 160 so that the carrier 160 to apply a force to the rotary arm 130 to provide a stepping force; It may include an actuator 180 for providing power to the power transmission member 170.

FIG. 1B is a view illustrating a state in which a vehicle accelerator pedal operation device of a general structure operates in a state in which a connection with a carrier is released. FIG. It is a figure which shows.

Referring to FIG. 1B, FIG. 1B illustrates a state in which a driver drives without using an AAP system (hereinafter, referred to as a passive mode). In this case, the carrier 160 is positioned at a predetermined initial angle by the actuator 180, the extension arm 133a or 133b is formed on the rotary arm 130, and the slot 163 is formed on the carrier 160. Is formed, the extension rod can move along the slot 163. At this time, the extension rod of the rotary arm 130 may move along the slot 163 from the initial position 133a to the maximum movement position 133b without being interfered with the carrier 160. Thus, the pedal pad 110a or 110b can also be rotated to freely reciprocate between the initial position 110a and the maximum movement position 110b.

Next, referring to FIG. 1C, FIG. 1C illustrates a case in which the driver wants to use the AAP system (hereinafter, referred to as an active mode). In this case, the carrier 160 may include an actuator (180 in FIG. 1A). , Hereinafter referred to as 180) and a power transmission member (170 of FIG. 1A, hereinafter referred to as 170) may be positioned by rotating at an angle θ from the initial position. The predetermined angle θ means the set angle of the carrier 160 corresponding to the position of the rotation arm 130 corresponding to the preset speed of the vehicle in order to transmit a warning to the driver.

At this time, since the extension rod 133a or 133c of the rotary arm 130 moves along the slot 163 of the carrier 160 and touches the end 165 of the slot 163, the interference occurs. By transmitting a force for rotating the power transmission member 170 and the actuator 180 to operate. In addition, the pedal pad 110a or 110c may reciprocate only between the initial position 110a and the maximum movement position 110c.

At this point, the driver is at a speed greater than or equal to a preset vehicle speed. At this time, the actuator 180 is operated to rotate the carrier 160 so as to transmit a response force to the extension rod 133 of the rotating arm 130. Can cause a warning.

However, the vehicle accelerator pedal operation device of this general structure applies a motor rotation and gear unit to reduce the rotational force and provide an additional power on the pedal, so that the time to reach the target power when providing the additional power is generated.

That is, referring to FIG. 1D, which is a graph of a pedal force of a vehicle acceleration pedal operating device having a general structure, when an extension rod of a rotating arm moves along a slot of a carrier and touches the end of the slot and interferes with it, a force for rotating the carrier is transmitted. Since the power is provided to the driver by the method of operating the power transmission member and the actuator, an error range B is generated in the process of transmitting the force between these components, thereby reaching the target power A to be provided. The response time until the longer becomes.

In addition, in the case of the vehicle acceleration pedal operating device having a general structure, since a plurality of gears are applied, there is a fear that the deviation between the gears may occur, noise may occur due to the movement of the gear.

Figure 2a is a cross-sectional view schematically showing a vehicle accelerator pedal operating device according to the present invention, Figure 2b is an enlarged perspective view showing the region X of Figure 2a.

First, referring to FIG. 2A, the vehicle accelerator pedal operation apparatus 200 according to the present invention may include a pedal arm 211, a rotation arm 230, and a linear motor unit 240.

The pedal arm 211 is used to increase the speed of the vehicle by controlling the amount of fuel and air supplied to the engine engine by manipulating the driver's foot to speed up the rotation of the engine.

At this time, a pedal pad 210 is connected to one end of the pedal arm 211. The pedal pad 210 has a substantially rectangular plate-like shape, and the driver may perform an angular rotational movement about the lower end of the pedal pad 210 to adjust the foot by adjusting the tip of the foot.

In addition, the pedal arm 211 may be connected to the lower end of the pedal pad 210 as a member having a straight or arc shape.

Meanwhile, the rotary arm 230 may be connected to one end of the opposite side of the pedal arm 211 connected to the pedal pad 210. At this time, the rotary arm connected to the other end of the pedal arm may be integrally formed with the pedal arm.

In addition, the rotary arm 230 may be configured to be rotatable about the hinge shaft 212 by the force transmitted from the pedal arm 211. That is, the rotary arm 230 connected to the pedal arm 211 is rotatable integrally with the pedal arm 211, and thus the pedal arm and the rotary arm rotate about the hinge axis 212 in the same direction. Done. That is, about the hinge axis, when the pedal arm rotates clockwise, the rotary arm also rotates clockwise, and when the pedal arm rotates counterclockwise, the rotary arm also rotates counterclockwise.

With continued reference to FIG. 2A, the vehicle accelerator pedal actuating device according to the present invention is located at the lower end of the rotary arm 230 and is connected to the rotary arm 230 to provide a force in the opposite direction of rotation of the rotary arm 230. The elastic member 220 may be provided.

That is, in order to accelerate the vehicle, when the pedal arm 211 is rotated counterclockwise by applying a force to the pedal pad 210 at the initial position, the rotation arm 230 also rotates counterclockwise about the hinge axis 212. In this case, the elastic member 220 is a compression force is applied to provide a force in the direction opposite to the rotation of the rotating arm. Subsequently, for deceleration of the vehicle, when the force is removed from the pedal pad 210, the rotating arm 230 rotates in a clockwise direction by the restoring force of the elastic member. At this time, the hinge arm 212 is centered. Since the pedal arm 211 also rotates clockwise, the pedal pad 210 can eventually be restored to its original position.

2A and 2B, the vehicle accelerator pedal operating apparatus according to the present invention controls the linear motor unit 240 and the linear motor unit 240 in contact with a predetermined region of the rotary arm 230. It may include a control circuit unit 260 for.

More specifically, the linear motor unit 240 has a rotary roller 241 and a rotating roller shaft 242 for supporting the rotating roller is formed at one end, the rotating roller shaft as an axis, the rotating roller is Can rotate

In addition, the rotary roller 241 is in contact with a predetermined region of the rotary arm 230. At this time, the rotating roller is preferably in contact with the upper end of the rotating arm, which rotates about the hinge axis, by the principle of the lever, the force applied to the rotating arm by the rotating roller farther from the hinge axis Because it grows.

In addition, it is preferable that the upper end of the rotating arm is inclined, and more specifically, it is preferable that the upper end contact surface of the rotating arm has an inclination angle of 80 ° to 110 ° with the linear movement axis of the linear motor part.

In this case, the case where the contact surface of the upper end of the rotating arm and the linear moving shaft of the linear motor portion is 90 degrees may be the case that the force applied to the rotating arm by the rotating roller is maximum, but the linear motor portion performs linear motion, and the rotating arm rotates. Because of their movement, the inclination angle cannot be kept at 90 ° during their movement.

In other words, if both the linear motor portion and the rotary arm are in a linear motion, or if both rotational movements are performed, the linear motor portion and the rotary arm may be moved while maintaining the inclination angle at 90 °. Since the point of contact with each other varies with each movement, the angle of inclination cannot be continuously maintained at 90 ° during movement.

Therefore, in order to maximize the force exerted on the rotating arm by the rotating roller, it is preferable that the upper end contact surface of the rotating arm has an inclination angle of 80 ° to 110 ° with the linear movement axis of the linear motor part.

On the other hand, the rotary roller 241 includes a magnet portion 231 at the upper end of the rotary arm 230 in order to contact a predetermined region of the rotary arm 230. Forming the magnet portion on the upper end of the rotating arm may be formed by forming a groove (not shown) in a predetermined region of the upper end of the rotating arm, and mounting the magnet in the groove. At this time, the upper end contact surface of the rotating arm described above corresponds to the magnet portion.

That is, by forming the rotary roller with a metal material, the rotary roller can be in magnetic contact with the magnet portion, and thus, the linear motor portion can be in contact with a predetermined region of the rotary arm.

In this case, the linear motor unit 240 is in a state of being in contact with the rotating arm, and is configured to provide a stepping force to the driver, which will be described later.

On the other hand, the vehicle acceleration pedal operating device according to the invention may include a housing 250 for receiving the hinge shaft 212, the elastic member 220 and the linear motor unit 240, the hinge shaft 212 The elastic member 220 and the linear motor unit 240 may be fixed to a predetermined region of the housing. In addition, the housing 250 may accommodate the rotation arm 230 and the control circuit unit 260 described above.

3 is a schematic cross-sectional view for explaining the operation of the linear motor unit according to the present invention.

Referring to FIG. 3, the linear motor part 240 according to the present invention includes a cylindrical second magnet part 245b and a first magnet part 245a inserted into the second magnet part 245b. And a cylindrical coil guide 246 inserted into a space between the second magnet part 245b and the first magnet part 245a and a coil part 247 positioned on the coil guide. . On the other hand, the rotary roller shaft and the rotary roller as described above may be located at the end of the coil guide.

In addition, as described above, the linear motor unit 240 is fixed to a certain region of the housing, the cylindrical second magnet portion 245b is fixed to a certain region of the housing, the first magnet portion 245a is The second magnet part 245b may be inserted into and fixed to the inside of the second magnet part 245b.

At this time, when a current is applied to the coil part, a magnetic force line is generated in the coil, and the coil guide is linearly moved (L-L direction) by the interaction of the generated magnetic force line with the first magnet part and the second magnet part. On the other hand, applying the current to the coil unit is the case that the driver uses the AAP system according to the present invention, the control of the application of current is possible through the control circuit unit for controlling the above-described linear motor unit, according to the current applied The coil guide may linearly move forward or backward in a space between the second magnet part and the first magnet part.

That is, when a current is applied to the coil, the rotary roller shaft and the rotary roller positioned in the coil guide are linearly moved by the linear motion of the coil guide. Since the operation of the linear motor is well known, a detailed description thereof will be omitted below.

4A is a view showing a state in which a driver drives without using the AAP system according to the present invention (hereinafter, referred to as a passive mode), and FIG. 4B shows the driver using the AAP system according to the present invention. This is a diagram showing a state in which driving is performed (hereinafter referred to as an active mode).

First, referring to FIG. 4A, when the pedal arm (not shown) is rotated counterclockwise by applying a force to the pedal pad (not shown), the rotation arm 230 is rotated about the hinge axis 212. ) Rotates counterclockwise (arrow direction).

At this time, since FIG. 4A is the passive mode, no current is applied to the linear motor unit 240, and thus, the rotary roller shaft 242 of the linear motor unit 240 and the rotary roller shaft 242 supporting the rotary roller are provided. Is linearly moved in the left direction (arrow direction) according to the rotation direction of the rotary arm 230.

In addition, when the force is removed from the pedal pad (not shown) for deceleration of the vehicle, the rotation arm 230 rotates in the clockwise direction by the restoring force of the elastic member 220, and at this time, the linear motor unit 240 Rotation roller 241 and the rotation roller shaft 242 supporting the rotation roller are linearly moved in the right direction according to the rotation direction of the rotation arm 230 because the rotation roller is attached to the magnet portion of the rotation arm. do.

That is, in the passive mode in which the driver operates without using the AAP system according to the present invention, since no current is applied to the linear motor unit, the rotary arm and the pedal arm have a rotational motion independent of the linear motor unit. The rotary roller and the rotary roller shaft move linearly along the direction of movement of the rotary arm.

Next, referring to FIG. 4B, when the pedal arm (not shown) is rotated counterclockwise by applying a force to the pedal pad (not shown) to rotate the vehicle, the rotary arm (2) is rotated about the hinge axis 212. 230 is rotated counterclockwise.

However, unlike in FIG. 4A, since FIG. 4B is an active mode, a current is applied to the linear motor unit 240. Therefore, the linear motor portion is a linear movement, by adjusting the applied current, the rotary roller 241 of the linear motor unit 240 and the rotary roller shaft 242 for supporting the rotary roller is the rotary arm 230 The linear motion is performed in the right direction (arrow direction) opposite to the rotation direction of.

As a result, as the rotary roller portion linearly moves in the direction opposite to the rotational direction of the rotary arm, the linear motor portion transmits the pedal force to the rotary arm, and thus the driver transmits the pedal force provided by the linear motor portion through the pedal arm and the pedal. You will be delivered.

In this case, when the driver uses the AAP system, the driver may preset a speed for operating the AAP system. Therefore, when the speed of the vehicle becomes greater than or equal to the preset speed, the driver applies a constant current to the linear motor unit in the linear motor controller. As a result, the linear motor portion can linearly move.

In addition, when the force is removed from the pedal pad (not shown) for deceleration of the vehicle, the rotating arm 230 rotates clockwise (arrow direction) by the restoring force of the elastic member 220, and at this time, the linear The rotating roller 241 of the motor unit 240 and the rotating roller shaft 242 supporting the rotating roller are applied with current, and still move linearly in the right direction (arrow direction). Of course, since the rotary roller shaft and the rotary roller are attached to the magnet portion of the rotary arm in addition to the linear motion by the application of this current, the rotary roller shaft and the rotary roller can move to the right direction in accordance with the rotation direction of the rotary arm.

4C is a diagram for explaining a passive mode assuming that a magnet part is not formed on the rotating arm.

First, in order to accelerate the vehicle, when the pedal arm (not shown) is rotated counterclockwise by applying a force to the pedal pad (not shown), as shown in FIG. 4A, the rotation arm 230 is rotated about the hinge shaft 212. ) Rotates counterclockwise (arrow direction).

Meanwhile, since FIG. 4C corresponds to the passive mode as shown in FIG. 4A, no current is applied to the linear motor unit 240, and therefore, the rotation supporting the rotary roller 241 and the rotary roller of the linear motor unit 240 is performed. The roller shaft 242 will move leftward according to the direction of rotation of the rotary arm 230.

However, even if the force is removed from the pedal pad (not shown) for deceleration of the vehicle, it is assumed in the case of FIG. 4C that the magnet part is not formed on the rotating arm, and thus, the rotary roller 241 of the linear motor part 240. ) And the rotary roller shaft 242 do not return along the rotary arm, but remain in the position where the force was applied to the pedal pad.

Therefore, in the passive mode assuming that no magnet part is formed in the rotating arm, when the force is applied to the pedal pad and the force is removed again, the space Y between the rotating roller 241 and the rotating arm 230 is generated. do.

At this time, when the passive mode is changed to the active mode in a state where the space Y between the rotary roller 241 and the rotary arm is generated, the rotary roller 241 and the rotary roller shaft 242 of the linear motor unit 240 are There is a sudden linear movement in the direction of the rotating arm, and the rotating roller hits the rotating arm with noise, causing the driver to feel unnecessary discomfort through the pedal pad.

Therefore, the vehicle acceleration pedal operating device according to the present invention forms the rotary roller with a metal material and forms the magnet portion in a predetermined region of the rotary arm, thereby allowing the rotary roller to be magnetized in the magnet portion in any of the passive mode and the active mode. By making a contact, ie, making a linear motor part contact a fixed area | region of a rotating arm, unnecessary discomfort by the collision of a rotating roller and a rotating arm can be improved.

5 is a graph of the power of the accelerator pedal operation device for a vehicle according to the present invention. In this case, in FIG. 5, the X axis represents an operating angle of the pedal, and the speed of the vehicle may increase according to the operating angle of the pedal, and the Y axis represents a load transmitted to the driver. In addition, area A indicates an area providing simple stepping force among loads transmitted to the driver, and area B indicates an area providing vibration among loads transmitted to the driver. However, the area providing the effort and the area providing the vibration are only examples, and the present invention is not limited thereto.

Referring to FIG. 5, it can be seen that the target effort to be provided in real time is reached without generating an error range in both the A and B regions.

That is, in FIG. 1d, which shows a graph of the pedal effort of a vehicle accelerator pedal operating device having a general structure, an error range B occurs in the process of transmitting forces between the components, until the target pedal A is provided. Although the response time is longer, in the present invention, since the linear motor unit directly transmits the turning force to the rotating arm, there is no separate configuration in which the force is transmitted while providing the turning force, thereby providing a real time without generating an error range. It can be seen that the target effort is reached.

Therefore, the vehicle accelerator pedal operation apparatus according to the present invention provides a direct power through the linear motor portion in contact with a predetermined region of the rotary arm, so that the target power can be reached without an error range.

Further, by making the rotary roller of the linear motor portion magnetically contact the magnet portion of the rotary arm, unnecessary discomfort caused by the collision of the rotary roller and the rotary arm can be improved.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
