In this embodiment, the first elastic member 70 may be a spring.

In the present embodiment, the first elastic member 70 is in a natural stretched state when the vehicle is not accelerating. When the driver's sole depresses 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 sole of the driver leaves the pedal assembly 20, the first elastic member 70 pulls the pedal assembly 20 to return to the original position under the elastic restoring force of the first elastic member 70.

When the driver steps on the pedal assembly 20, the pedal assembly 20 drives the accelerator arm 30 to move downward, and at the same time, the accelerator arm 30 stretches the second elastic member 80. When the driver's sole leaves the pedal assembly 20, the second elastic member 80 pulls the throttle arm 30 to return to its original position under the elastic restoring force of the second elastic member 80.

In this embodiment, in order to improve the driving comfort of the driver, the area of the pedal 202 may be increased to improve the contact area between the pedal 202 and the sole of the driver, so that the pedal 202 can be attached to the sole of the driver. At the same time, the patterns on the surface of the pedal 202 can be increased to improve the driving comfort of the driver.

In this embodiment, in order to facilitate the driver's stepping on the pedal 202, referring to fig. 1 and 2, the pedal arm 201 includes: a first connection 2011 and a second connection 2012.

The first limiting piece 203 is arranged in the limiting groove 302, when acceleration is finished, if the second elastic piece 80 is damaged, the accelerator support arm 30 cannot be driven to return to the original position, the pedal support arm 201 returns to the original position under the action of the first elastic piece 70, at the moment, the pedal support arm 201 drives the accelerator support arm 30 to return to the original position through the first limiting piece 203, so that double insurance is realized, traffic accidents are avoided, driving safety can be guaranteed, and meanwhile, the accelerator support arm 30 is pressed on the first limiting piece 203, and the lifting stroke of the pedal support arm 201 is limited.

In some embodiments, and with reference to fig. 2, to effect linkage of the pedal assembly 20 and the throttle arm 30, the linkage assembly 40 includes: a first sliding sleeve 401, a linkage member 402, a second limiting member 403 and a third elastic member 404. The first runner 401 is provided on the pedal assembly 20. Specifically, the first sliding sleeve 401 is disposed on the second connection 2012 of the pedal assembly 20. The linkage 402 is disposed through the first sliding sleeve 401 and is switchable between a first position and a second position. The second limiting member 403 is disposed at an 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 is disposed between the first sliding sleeve 401 and the second limiting member 403. Wherein the linkage 402 is coupled to the throttle arm 30 when the linkage 402 is in the first position, and the linkage 402 is decoupled from the throttle arm 30 when the linkage 402 is in the second position.

When acceleration is finished, the sole of the driver leaves the driving assembly 60, the driving assembly 60 returns to the original position, at this time, the driving assembly 60 drives the linkage piece 402 to act through the transmission assembly 50, the linkage piece 402 returns to the second position, so that the linkage piece 402 is separated from the accelerator support arm 30, and the linkage piece 402 is separated from the accelerator support arm 30, in this state, even if the pedal assembly 20 is blocked by other foreign matters such as an interior trim or an unofficial foot pad which is additionally arranged in the vehicle, the accelerator support arm 30 can also rotate on the bracket 10, so that the accelerator support arm 30 returns to the original position, and the accelerator sensor sends an oil-break signal to the engine ECU, so that the vehicle accelerator is closed, the occurrence of traffic accidents is avoided, and the driving safety can be ensured.
