Traditionally, the accelerator pedal is connected to the throttle via a throttle cable or lever. However, with the continuous advancement of automotive electronics, electronic throttles are becoming increasingly common. When the driver steps on an electronic throttle pedal, an accelerator pedal position sensor signal is transmitted to the engine's ECU (Electronic Control Unit).

[0022] The beneficial effects of the present invention include at least:

[0023] In the prior art, accelerator pedals are often designed to fit snugly under the driver's foot, thereby improving driving comfort. This is often done by increasing the area of the accelerator pedal and adding a textured pattern to the pedal surface to increase the contact area between the accelerator pedal and the driver's foot. However, after the driver steps on the accelerator pedal, it can easily become stuck on foreign objects such as interior trim or unofficial floor mats. This can prevent the driver from lifting their foot, potentially leading to traffic accidents.

[0024] Since the pedal assembly is rotatably connected to the bracket, the throttle arm is rotatably connected to the bracket, the linkage assembly is slidably provided on the pedal assembly and can be switched between a first position and a second position, the transmission assembly is rotatably provided on the pedal assembly and is connected to the linkage assembly, the drive assembly is passed through the pedal assembly and is connected to the transmission assembly to drive the linkage assembly to switch between the first position and the second position. Therefore, when acceleration is required, the driver's foot steps down, and the driver's foot will first conflict with the drive assembly to step on the drive assembly. At this time, the drive assembly passes through the pedal assembly to drive the transmission assembly to move, and the transmission assembly drives the linkage assembly to move, so that the linkage assembly reaches the first position. When the linkage assembly reaches the first position, the linkage assembly is connected to the throttle arm, so that the throttle arm and the pedal assembly become a whole. Then, the driver's foot Continue to step on the pedal, the driver's foot will come into contact with the pedal assembly, so that the pedal assembly rotates on the bracket, and the pedal assembly drives the throttle arm to rotate on the bracket, and the throttle arm is connected to the throttle sensor. The throttle sensor sends an acceleration signal to the engine ECU to accelerate the vehicle. When the acceleration is completed, the driver's foot will leave the drive assembly and the drive assembly will return to its original position. At this time, the drive assembly drives the linkage assembly to move through the transmission assembly, so that the linkage assembly is in the second position, and the linkage assembly is separated from the throttle arm. In this state, even if the pedal assembly is stuck by other foreign objects such as the interior installed in the vehicle or unofficial floor mats, the throttle arm can also rotate on the bracket to return the throttle arm to its original position, and the throttle sensor sends a fuel cut-off signal to the engine ECU to close the vehicle throttle, avoid traffic accidents, and ensure driving safety.

[0049] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0050] The accelerator pedal and vehicle provided in this embodiment are intended to at least to some extent solve the technical problem that the accelerator pedal is easily stuck with foreign objects, resulting in the accelerator pedal being unable to be lifted after the driver lifts his foot, thereby causing traffic accidents.

[0051] Figure 1 Schematic diagram of the structure of the accelerator pedal of this embodiment; Figure 2 for Figure 1 Schematic diagram of the structure of the transmission component of the accelerator pedal. Figure 1 and Figure 2The throttle pedal of this embodiment includes: a bracket 10, a pedal assembly 20, a throttle arm 30, a linkage assembly 40, a transmission assembly 50 and a drive assembly 60. The pedal assembly 20 is rotatably connected to the bracket 10. The throttle arm 30 is rotatably connected to the bracket 10. The linkage assembly 40 is slidably provided on the pedal assembly 20 and can be switched between a first position and a second position. The transmission assembly 50 is rotatably provided on the pedal assembly 20 and is connected to the linkage assembly 40. The drive assembly 60 is provided through the pedal assembly 20 and is connected to the transmission assembly 50 to drive the linkage assembly 40 to switch between the first position and the second position. Specifically, when the linkage assembly 40 is in the first position, the linkage assembly 40 is connected to the throttle arm 30, and when the linkage assembly 40 is in the second position, the linkage assembly 40 is separated from the throttle arm 30.

[0052] The bracket 10 is installed in the vehicle and is located at the driver's seat.

[0053] The throttle arm 30 is connected to the throttle sensor.

[0054] In the prior art, accelerator pedals are often designed to fit snugly under the driver's foot, thereby improving driving comfort. This is often done by increasing the area of the accelerator pedal and adding a textured pattern to the pedal surface to increase the contact area between the accelerator pedal and the driver's foot. However, after the driver steps on the accelerator pedal, it can easily become stuck on foreign objects such as interior trim or unofficial floor mats. This can prevent the driver from lifting their foot, potentially leading to traffic accidents.

[0055] Since the pedal assembly 20 is rotatably connected to the bracket 10, the throttle arm 30 is rotatably connected to the bracket 10, the linkage assembly 40 is slidably provided on the pedal assembly 20 and can be switched between the first position and the second position, the transmission assembly 50 is rotatably provided on the pedal assembly 20 and is connected to the linkage assembly 40, and the drive assembly 60 is passed through the pedal assembly 20 and is connected to the transmission assembly 50 to drive the linkage assembly 40 to switch between the first position and the second position. Therefore, when acceleration is required, the driver's foot steps down, and the driver's foot will first conflict with the drive assembly 60 to step on the drive assembly 60. At this time, the drive assembly 60 passes through the pedal assembly 20 to drive the transmission assembly 50 to move, and the transmission assembly 50 drives the linkage assembly 40 to move, so that the linkage assembly 40 reaches the first position. When the linkage assembly 40 reaches the first position, the linkage assembly 40 is connected to the throttle arm 30, so that the throttle arm 30 and the pedal assembly 20 become a whole. , the driver's foot continues to step down, and the driver's foot contacts the pedal assembly 20, causing the pedal assembly 20 to rotate on the bracket 10, and the pedal assembly 20 drives the throttle arm 30 to rotate on the bracket 10, and the throttle arm 30 is connected to the throttle sensor. The throttle sensor sends an acceleration signal to the engine ECU to accelerate the vehicle. When the acceleration is completed, the driver's foot will leave the drive assembly 60, and the drive assembly 60 will return to its original position. At this time, the drive assembly 60 drives the linkage assembly 40 through the transmission assembly 50 to move, so that the linkage assembly 40 is in the second position, and the linkage assembly 40 is separated from the throttle arm 30. In this state, even if the pedal assembly 20 is stuck by other foreign objects such as the interior installed in the vehicle or unofficial floor mats, the throttle arm 30 can still rotate on the bracket 10 to return to its original position. The throttle sensor sends a fuel cut-off signal to the engine ECU to close the vehicle throttle, avoiding traffic accidents and ensuring driving safety.

[0056] In some embodiments, when the driver is driving a car, the driver may step on the pedal assembly 20 due to an error. However, if the edge of the pedal assembly 20 is stepped on, the driving assembly 60 will not be triggered, and the pedal assembly 20 will not drive the throttle arm 3 to move, thereby effectively reducing the danger of accidentally stepping on the accelerator while driving.

[0057] Figure 3 for Figure 1 Schematic diagram of the structure of the accelerator pedal bracket. Figure 1 and Figure 3In some embodiments, to ensure that the pedal assembly 20 and the throttle arm 30 rotate smoothly within the bracket 10, the bracket 10 includes a mounting plate 101, a suspension shaft 102, and two lugs 103. The two lugs 103 are disposed on the mounting plate 101, and the two ends of the suspension shaft 102 are connected to the two lugs 103, respectively. A first bushing 104 is disposed on the suspension shaft 101, and the pedal assembly 20 is connected to the first bushing 104 so that the pedal assembly 20 can rotate on the suspension shaft 101. A second bushing 105 is disposed on the suspension shaft 101, and the throttle arm 30 is connected to the second bushing 105 so that the throttle arm 30 can rotate on the suspension shaft 101.

[0058] Combine Figure 1 and Figure 3 In this embodiment, the first sleeve 104 and the second sleeve 105 are arranged in parallel and spaced apart on the suspension shaft 101 to avoid interference between the rotation of the pedal assembly 20 on the suspension shaft 101 and the rotation of the throttle arm 30 on the suspension shaft 101, thereby ensuring smooth rotation of the pedal assembly 20 and the throttle arm 30 on the suspension shaft 101.

[0059] Combine Figure 1 and Figure 3 In this embodiment, in order to facilitate the connection between the bracket 10 and the vehicle body, a mounting hole 106 is opened on the mounting plate 101, so that the third connecting member is passed through the mounting hole 106 and connected to the vehicle body, while also achieving weight reduction.

[0060] Combine Figure 1 and Figure 3 In some embodiments, after the vehicle accelerates, in order to restore the pedal assembly 20 to its original position, the accelerator pedal further includes a first elastic member 70 connected to the bracket 10 and the pedal assembly 20. In this embodiment, the first elastic member 70 can be a spring.

[0061] In this embodiment, when the vehicle is not accelerating, the first elastic member 70 is in a naturally extended state. When the driver's foot steps on the pedal assembly 20, the pedal assembly 20 moves downward, and at the same time, the pedal assembly 20 stretches the first elastic member 70. When the driver's foot leaves the pedal assembly 20, the elastic restoring force of the first elastic member 70 pulls the pedal assembly 20 back to its original position.

[0062] Combine Figure 1 and Figure 3 In this embodiment, in order to facilitate the connection between the first elastic member 70 and the bracket 10, a first connecting hole 107 is opened on the bracket 10, and a first connecting seat 90 is provided on the pedal assembly 20. One end of the first elastic member 70 is connected to the first connecting hole 107, and the other end is connected to the first connecting seat 90.

[0063] Combine Figure 1 and Figure 3 In some embodiments, after the vehicle accelerates, in order to return the throttle arm 30 to its original position, the throttle pedal further includes a second elastic member 80 connected to the bracket 10 and the throttle arm 30 assembly. In this embodiment, the second elastic member 80 can be a spring.

[0064] In this embodiment, when the vehicle is not accelerating, the second elastic member 80 is in a naturally extended state. When the driver's foot depresses the pedal assembly 20, the pedal assembly 20 drives the throttle arm 30 downward, and the throttle arm 30 simultaneously stretches the second elastic member 80. When the driver's foot leaves the pedal assembly 20, the elastic restoring force of the second elastic member 80 pulls the throttle arm 30 back to its original position.

[0065] Combine Figure 1 and Figure 3 In this embodiment, in order to facilitate the connection between the second elastic member 80 and the bracket 10, a second connecting hole 108 is opened on the bracket 10, and a second connecting seat 100 is provided on the throttle arm 30. One end of the second elastic member 80 is connected to the second connecting hole 108, and the other end is connected to the second connecting seat 100.

[0066] Combine Figure 1 and Figure 3 In this embodiment, a first connecting hole 107 is formed on one of the two supporting ears 103 of the bracket 10, and a second connecting hole 108 is formed on the other of the two supporting ears 103 of the bracket 10. That is, the first connecting hole 107 is opposite to the second connecting hole 108, so that the first elastic member 70 is opposite to the second elastic member 80, thereby avoiding interference between the movement of the first elastic member 70 and the movement of the second elastic member 80.

[0067] Combine Figure 1 and Figure 2 In some embodiments, to facilitate the driver's pedaling, the pedal assembly 20 includes a pedal arm 201 and a pedal 202. The pedal arm 201 is rotatably connected to the bracket 10. Specifically, the pedal arm 201 is connected to the first shaft sleeve 104. The pedal 202 is disposed at the end of the pedal arm 201 facing away from the bracket 10. When the driver steps down with the sole of the foot, the sole of the foot contacts the pedal 202, thereby depressing the pedal 202, which drives the pedal arm 201 to rotate on the bracket 10.

[0068] In this embodiment, to improve the driver's driving comfort, the area of the pedal 202 can be increased to increase the contact area between the pedal 202 and the driver's foot so that the pedal 202 can fit the driver's foot. At the same time, the surface pattern of the pedal 202 can also be increased to improve the driver's driving comfort.

[0069] Combine Figure 1 and Figure 2 In this embodiment, to facilitate the driver's stepping on the pedal 202, the pedal arm 201 includes: a first connecting portion 2011 and a second connecting portion 2012. The first connecting portion 2011 is rotatably connected to the bracket 10. Specifically, the first connecting portion 2011 is connected to the first shaft sleeve 104. One end of the second connecting portion 2012 is connected to the first connecting portion 2011, and the other end is connected to the pedal 202. The second connecting portion 2012 is arranged at an angle to the first connecting portion 2011 to conform to ergonomics and facilitate the driver's stepping. In this embodiment, the angle between the second connecting portion 2012 and the first connecting portion 2011 can be an obtuse angle.

[0070] In this embodiment, the driver steps down with his foot, and the driver's foot contacts the pedal 202 to step down the pedal 202, which drives the second connection part 2012 to move, and the second connection part 2012 drives the first connection part 2011 to rotate on the bracket 10.

[0071] In this embodiment, in order to prevent the first elastic member 70 from interfering with the driver's foot stepping on the pedal 202, the first elastic member 70 is connected to the first connecting portion 2011, that is, the first connecting seat 90 is arranged on the first connecting portion 2011 so that there is a distance between the first elastic member 70 and the pedal 202 to prevent the driver's foot from stepping on the first elastic member 70.

[0072] In this embodiment, the length of the first connecting portion 2011 matches the length of the throttle arm 30, that is, the length of the throttle arm 30 is less than the length of the pedal arm 201. It can be understood that the throttle arm 30 is suspended to prevent the throttle arm 30 from being stuck by other foreign objects such as interior decoration installed in the vehicle or unofficial floor mats.

[0073] In this embodiment, in order to save space and ensure aesthetics, the first connecting portion 2011 is opposite to the throttle arm 30, that is, the first connecting portion 2011 is aligned with the throttle arm 30. At the same time, there is a distance between the first connecting portion 2011 and the throttle arm 30 so that the first connecting portion 2011 and the throttle arm 30 exist independently.

[0074] Combine Figure 1In this embodiment, to ensure that the throttle arm 30 can return to its original position, a first stopper 203 is provided on the pedal arm 201. Specifically, the first stopper 203 is located at the end of the first connecting portion 2011 of the pedal arm 201 facing away from the bracket 10. A stopper slot 302 is defined in the throttle arm 30. Specifically, the stopper slot 302 is defined at the end of the throttle arm 30 facing away from the bracket 10. The first stopper 203 is located within the stopper slot 302. When acceleration is complete, if the second elastic member 80 is damaged and unable to return the throttle arm 30 to its original position, the first elastic member 70 will activate the pedal arm 201 to return to its original position. At this point, the pedal arm 201, driven by the first stopper 203, will return to its original position, providing a double safeguard against traffic accidents and ensuring driving safety. Furthermore, the throttle arm 30 presses against the first stopper 203, limiting the lift travel of the pedal arm 201.

[0075] Combine Figure 2 In some embodiments, to achieve linkage between the pedal assembly 20 and the throttle arm 30, the linkage assembly 40 includes a first sleeve 401, a linkage member 402, a second stopper 403, and a third elastic member 404. The first sleeve 401 is disposed on the pedal assembly 20. Specifically, the first sleeve 401 is disposed on the second connecting portion 2012 of the pedal assembly 20. The linkage member 402 is inserted into the first sleeve 401 and can be switched between a first position and a second position. The second stopper 403 is disposed at the end of the linkage member 402 facing away from the throttle arm 30. The third elastic member 404 is sleeved on the linkage member 402 and disposed between the first sleeve 401 and the second stopper 403. When the linkage member 402 is in the first position, the linkage member 402 is connected to the throttle arm 30. When the linkage member 402 is in the second position, the linkage member 402 is separated from the throttle arm 30.

[0076] In this embodiment, when acceleration is required, the driver's foot steps down, and the driver's foot will first conflict with the drive assembly 60 to step on the drive assembly 60. At this time, the drive assembly 60 drives the transmission assembly 50 through the pedal assembly 20 to move, and the transmission assembly 50 drives the linkage member 402 to move in the first sleeve 401. The linkage member 402 is limited by the first sleeve 401 to ensure that the linkage member 402 can reach the first position. When the linkage member 402 reaches the first position, the linkage member 402 is connected to the throttle arm 30 so that the throttle arm 30 and the pedal assembly 20 become a whole. Then, the driver's foot continues to step down, and the driver's foot conflicts with the pedal assembly 20, so that the pedal assembly 20 rotates on the bracket 10. The pedal assembly 20 drives the throttle arm 30 to rotate on the bracket 10, and the throttle arm 30 is connected to the throttle sensor. The throttle sensor sends an acceleration signal to the engine ECU to achieve vehicle acceleration. When acceleration is completed, the driver's foot will leave the drive assembly 60, and the drive assembly 60 will return to its original position. At this time, the drive assembly 60 drives the linkage member 402 to move through the transmission assembly 50, and the linkage member 402 returns to the second position to separate the linkage member 402 from the throttle arm 30 to ensure that the linkage member 402 is separated from the throttle arm 30. In this state, even if the pedal assembly 20 is stuck by other foreign objects such as the interior decoration installed in the vehicle or unofficial floor mats, the throttle arm 30 can also rotate on the bracket 10 to return the throttle arm 30 to its original position, and the throttle sensor will send the fuel cut-off signal to the engine ECU to realize the vehicle throttle closing, avoid traffic accidents, and ensure driving safety.

[0077] In this embodiment, in order to ensure the stability of the connection between the linkage member 402 and the second position-limiting member 403 , the linkage member 402 and the second position-limiting member 403 may be integrally formed.

[0078] In this embodiment, when the linkage member 402 reaches the first position, the linkage member 402 drives the second limiting member 403 to move, and the second limiting member 403 compresses the third elastic member 404. When the driver's foot leaves the drive assembly 60, the elastic restoring force of the third elastic member 404 pushes the second limiting member 403 back to its original position, and the second limiting member 403 also drives the linkage member 402 back to the second position. Under the combined action of the transmission assembly 50 and the third elastic member 404, the linkage member 402 is separated from the throttle arm 30, achieving double insurance to ensure that the linkage member 402 is completely separated from the throttle arm 30.

[0079] Combine Figure 2In this embodiment, since the length of the linkage 402 is relatively long, in order to ensure that the linkage 402 can smoothly switch between the first position and the second position, the linkage assembly 40 also includes a second sliding sleeve 405 provided on the pedal assembly 20, and the linkage 402 is sequentially passed through the first sliding sleeve 401 and the second sliding sleeve 405. The first sliding sleeve 401 and the second sliding sleeve 405 are used to jointly limit the linkage 402 to ensure that the linkage 402 can move along the set path, avoid the linkage 402 from being offset, and enable the linkage 402 to switch between the first position and the second position.

[0080] Combine Figure 2 In this embodiment, in order to facilitate the connection between the linkage member 402 and the throttle arm 30 when the linkage member 402 is in the first position, a linkage groove 301 is formed on the throttle arm 30. When the linkage member 402 is in the first position, the linkage member 402 is embedded in the linkage groove 301. When the linkage member 402 is in the second position, the linkage member 402 is separated from the linkage groove 301. It is understood that during the process of switching the linkage member 402 from the second position to the first position, the linkage member 402 can be directly inserted into the linkage groove 301 to facilitate the connection between the linkage member 402 and the throttle arm 30. During the process of switching the linkage member 402 from the first position to the second position, the linkage member 402 can be directly withdrawn from the linkage groove 301 to facilitate the separation of the linkage member 402 from the throttle arm 30.

[0081] In this embodiment, to facilitate insertion of the linkage member 402 into the linkage slot 301, the cross-sectional shape of the end of the linkage member 402 facing the throttle arm 30 matches the cross-sectional shape of the linkage slot 301. In this embodiment, the cross-sectional shape of the linkage slot is a parallelogram.

Figure 7 and Figure 8In this embodiment, to minimize differences from conventional accelerator pedals, the pedal assembly 20 and the throttle arm 30 can be permanently locked together. The accelerator pedal further includes a locking member 407 connected to the pedal assembly 20. When the linkage member 402 is in the first position, the locking member 407 is disposed through the pedal assembly 20 and connected to the linkage member 402. The locking member 407 positions the linkage member 402 so that the linkage member 402 remains in the first position, ensuring that the pedal assembly 20 and the throttle arm 30 form a single unit. At this point, the pressing member 603 of the drive assembly 60 does not protrude from the pedal 202 of the pedal assembly 20, ensuring that the pressing member 603 of the drive assembly 60 is flush with the surface of the pedal 202 of the pedal assembly 20. This effectively minimizes differences from conventional pedals and improves user comfort.

[0083] Combine Figure 7 and Figure 8 4021 , when the pedal assembly 20 is in the first position, the first through hole 4011 is connected to the second through hole 4021 , and the locking member 407 is sequentially passed through the pedal assembly 20 and the first through hole 4011 , and is arranged in the second through hole 4021 . The position of the linkage member 402 is determined by the locking member 407 so that the linkage member 402 is always in the first position to ensure that the pedal assembly 20 and the throttle arm 30 become a whole. At this time, the pressing member 603 of the driving assembly 60 will not protrude from the pedal 202 of the pedal assembly 20, so that the pressing member 603 of the driving assembly 60 is flush with the surface of the pedal 202 of the pedal assembly 20, effectively reducing the difference from the existing ordinary pedals and effectively improving the comfort of use.

[0084] Combine Figure 1 and Figure 7 In this embodiment, in order to ensure aesthetics, the pedal assembly 20 also includes a cover 204, which is connected to the second connecting portion 2012 of the pedal assembly 20. The transmission assembly 50 and the linkage assembly 40 are arranged in the cover 204, and the linkage assembly 40 is covered by the cover 204 to prevent the linkage assembly 40 from being exposed to the outside.

[0085] In this embodiment, a third through hole is provided on the cover body 204. When the linkage member 402 is in the first position, the third through hole, the first through hole 4011 and the second through hole 4021 are connected. The locking member 407 is sequentially passed through the third through hole and the first through hole 4011 and is arranged in the second through hole 4021. The position of the linkage member 402 is determined by the locking member 407 so that the linkage member 402 is always in the first position to ensure that the pedal assembly 20 and the throttle arm 30 become a whole. At this time, the pressing member 603 of the driving assembly 60 will not protrude from the pedal 202 of the pedal assembly 20, so that the pressing member 603 of the driving assembly 60 is flush with the surface of the pedal 202 of the pedal assembly 20, effectively reducing the difference from the existing ordinary pedals and effectively improving the comfort of use.

[0086] In this embodiment, the locking member 407 may be a threaded rod, so that the locking member 407 passes through the third through hole and the first through hole 4011 in sequence, and is disposed in the second through hole 4021 .

[0087] Combine Figure 1 、 Figure 7 and Figure 8 In this embodiment, to facilitate the operation of the locking member 407, a knob 406 is provided on the end surface of the locking member 407 facing away from the first sliding sleeve 401. The driver can operate the knob 406 to drive the locking member 407 to operate, thereby facilitating operation. To further facilitate the driver's operation, the knob 406 can be a plum blossom knob.

[0088] Combine Figure 2 In some embodiments, the transmission assembly 50 includes a first transmission rod 501 and a second transmission rod 502. The first transmission rod 501 is connected to the drive assembly 60, and the middle portion of the first transmission rod 501 is rotatably mounted on the pedal assembly 20. Specifically, the second connecting portion 2012 of the pedal assembly 20 is provided with a rotating shaft 205, and the middle portion of the first transmission rod 501 is rotatably mounted on the rotating shaft 205. One end of the second transmission rod 502 is hingedly connected to the end of the second transmission rod 502 facing away from the drive assembly 60, and the other end is hingedly connected to the linkage assembly 40.

[0089] In this embodiment, when acceleration is required, the driver's foot steps down, and the driver's foot will first conflict with the drive assembly 60 to step on the drive assembly 60. At this time, the drive assembly 60 drives one end of the first transmission rod 501 downward through the pedal assembly 20, and the middle part of the first transmission rod 501 rotates on the rotating shaft 205. Using the principle of leverage, the other end of the first transmission rod 501 moves upward, and the other end of the first transmission rod 501 drives the second transmission rod 502 to move upward, and the linkage member 402 of the linkage assembly 40 moves upward through the second transmission rod 502, so that the linkage assembly 4 0 reaches the first position. When the linkage member 402 of the linkage assembly 40 reaches the first position, the linkage member 402 of the linkage assembly 40 is connected to the throttle arm 30, so that the throttle arm 30 and the pedal assembly 20 become a whole. Then, the driver's foot continues to step down, and the driver's foot conflicts with the pedal assembly 20, so that the pedal assembly 20 rotates on the bracket 10. The pedal assembly 20 drives the throttle arm 30 to rotate on the bracket 10, and the throttle arm 30 is connected to the throttle sensor. The throttle sensor sends an acceleration signal to the engine ECU to accelerate the vehicle. When acceleration is completed, the driver's foot will leave the drive assembly 60, and the drive assembly 60 will return to its original position. At this time, the drive assembly 60 drives one end of the first transmission rod 501 to move upward. At this time, the middle part of the first transmission rod 501 rotates on the rotating shaft 205. Using the principle of leverage, the other end of the first transmission rod 501 moves downward, and the other end of the first transmission rod 501 drives the second transmission rod 502 to move downward. The second transmission rod 502 drives the linkage member 402 of the linkage assembly 40 to move downward, so that the linkage member 402 of the linkage assembly 40 is located in the second position, and the linkage assembly 40 is separated from the throttle arm 30. In this state, even if the pedal assembly 20 is stuck by other foreign objects such as the interior decoration installed in the vehicle or unofficial floor mats, the throttle arm 30 can also rotate on the bracket 10 to return the throttle arm 30 to its original position, and the throttle sensor sends the fuel cut-off signal to the engine ECU to realize the vehicle throttle closing, avoid the occurrence of traffic accidents, and ensure driving safety.

[0090] Combine Figure 2 In this embodiment, to facilitate the connection between the transmission assembly 50 and the linkage assembly 40, the transmission assembly 50 further includes a first connecting member 503 provided on the linkage assembly 40. Specifically, the first connecting member 503 is provided on the linkage member 402 of the linkage assembly 40. The first connecting member 503 is hingedly connected to the second transmission rod 502 to achieve the connection between the second transmission rod 502 and the linkage member 402 of the linkage assembly 40.

Figure 4 、 Figure 5 and Figure 6 In some embodiments, the drive assembly 60 includes: a shell 601, a cover plate 602, a pressing member 603, a fourth elastic member 604 and a transmission member 605. The shell 601 is arranged in the pedal assembly 20. Specifically, the shell 601 is arranged between the pedal 202 and the pedal arm 201 of the pedal assembly 20. The cover plate 602 is arranged on the shell 601. The pressing member 603 is sequentially passed through the pedal assembly 20 and the cover plate 602 is arranged in the shell 601. The fourth elastic member 604 is arranged in the shell 601 and conflicts with the pressing member 603. One end of the transmission member 605 is connected to the pressing member 603, and the other end is passed through the shell 601 and hinged to the transmission assembly 50. Specifically, the transmission member 605 is hinged to the first transmission rod 501 of the transmission assembly 50. In this embodiment, the fourth elastic member 604 can be a spring.

[0092] In this embodiment, when acceleration is required, the driver's foot steps down, and the driver's foot will first conflict with the pressing member 603 to step on the pressing member 603 until the pressing member 603 is flush with the pedal 202 of the pedal assembly 20. At this time, the pressing member 603 passes through the pedal 202 of the pedal assembly 20 and moves in the housing 601 to squeeze the fourth elastic member 604. At the same time, the pressing member 603 will also drive the transmission member 605 to move downward, and the transmission member 605 drives one end of the first transmission rod 501 of the transmission assembly 50 to move downward. The middle part of the first transmission rod 501 rotates on the rotating shaft 205. Using the principle of leverage, the other end of the first transmission rod 501 moves upward, and the other end of the first transmission rod 501 drives the second transmission rod 5 02 moves upward, and drives the linkage part 402 of the linkage assembly 40 to move upward through the second transmission rod 502, so that the linkage part 402 of the linkage assembly 40 reaches the first position. When the linkage part 402 of the linkage assembly 40 reaches the first position, the linkage part 402 of the linkage assembly 40 is connected to the throttle arm 30, so that the throttle arm 30 and the pedal assembly 20 become a whole. Then, the driver's foot continues to step down, and the driver's foot conflicts with the pedal assembly 20, so that the pedal assembly 20 rotates on the bracket 10, and the pedal assembly 20 drives the throttle arm 30 to rotate on the bracket 10, and the throttle arm 30 is connected to the throttle sensor, and the throttle sensor sends an acceleration signal to the engine ECU to accelerate the vehicle. When the acceleration is completed, the driver's foot will leave the pressing member 603. Under the action of the elastic restoring force of the fourth elastic member 604, the fourth elastic member 604 pushes the pressing member 603 to pass through the pedal 202 of the pedal assembly 20 to return to its original position, so that the pressing member 603 protrudes from the pedal 202. At this time, the pressing member 603 drives the transmission member 605 to move upward, and the transmission member 605 drives one end of the first transmission rod 501 of the transmission assembly 50 to move upward. At this time, the middle part of the first transmission rod 501 rotates on the rotating shaft 205. Using the principle of leverage, the other end of the first transmission rod 501 moves downward, and the first transmission rod 501 The other end of the second transmission rod 502 drives the second transmission rod 502 to move downward, and the linkage part 402 of the linkage assembly 40 is driven downward by the second transmission rod 502 to make the linkage part 402 of the linkage assembly 40 be located in the second position, and the linkage assembly 40 is separated from the throttle arm 30. In this state, even if the pedal assembly 20 is stuck by other foreign objects such as the interior decoration installed in the vehicle or unofficial floor mats, the throttle arm 30 can also rotate on the bracket 10 to make the throttle arm 30 return to its original position, and the throttle sensor sends the fuel cut-off signal to the engine ECU to realize the vehicle throttle closing, avoid the occurrence of traffic accidents, and ensure driving safety.

The first through slot 2021 is connected to the second through slot 6021, and the pressing member 603 is sequentially passed through the first through slot 2021 and the second through slot 6021 in sequence and is arranged in the shell 601.

[0094] In this embodiment, the shape of the pressing member 603 matches the shape of the first through-slot 2021 and the second through-slot 6021. In this embodiment, the shape of the pressing member 603 can be one of a cross, a polygon, a triangle, or a circle. However, for ease of manufacture and aesthetics, the pressing member 603 is preferably in the shape of a cross.
