The accelerator pedal of modern vehicles mostly adopts an electronic accelerator pedal, particularly on small vehicles. When the vehicle normally runs, the vehicle speed is controlled by the depth of stepping on the accelerator pedal, the general pedal sensitivity is high, the stepping depth is determined by the stepping force, and the vehicle speed is higher when the vehicle is stepped deeper. When the vehicle runs on an uneven road surface, the vehicle and feet shake, pedals can be trampled in different degrees, so that the vehicle speed is unstable, and the stability and safety of the vehicle running are not facilitated. The addition of the damping of the accelerator pedal increases the driving stability and safety, but also reduces the sensitivity of the pedal, and the conditions of using the damping pedal in the whole vehicle factory are different at present.

The specific implementation mode of the present disclosure includes a pedal assembly 1, a damping element 2 for applying pressure to the pedal assembly 1, and a damping adjustment mechanism 3, wherein the damping adjustment mechanism 3 adjusts the pressure applied to the pedal assembly 1 by the damping element 2 by driving the damping element 2 to move.

When the damping element 2 and the pedal assembly 1 are in a non-contact state, the pedal is in a non-damping state; after the damping element 2 is in contact with the pedal assembly 1, along with the fact that the pressure applied to the pedal assembly 1 by the damping element 2 is larger and larger, the damping friction force of the damping element 2 to the pedal assembly 1 is larger and larger, the pressure applied to the pedal assembly 1 by the damping element 2 is controllably adjusted through the damping adjusting mechanism 3, adjustability of pedal damping is achieved, and a driver can adjust the size of the pedal damping according to personal requirements.

In the specific embodiment, the damping element 2 is provided with the pull ring, when the pull ring is pulled, the damping element 2 simultaneously applies pressure to the pedal assembly 1, the pressure is in direct proportion to the pull force, and the pressure applied to the pedal assembly 1 by the damping element 2 can be adjusted by adjusting the pull force; in addition, a plurality of buckles can be arranged on the moving path of the damping element 2, the damping element 2 can be fixed at different positions by the buckles, and the pressure applied to the pedal assembly 1 by the damping element 2 corresponding to the buckles at different positions is different.

Specifically, as shown in fig. 3, the damping adjustment mechanism 3 of the present embodiment includes an operating shaft 3-1 provided on the damping element 2, and the operating shaft 3-1 adjusts the amount of pressure applied to the pedal assembly 1 by the damping element 2 by moving in the index gap 3-2. Thus, the pressure applied by the damping element 2 to the pedal assembly 1 is determined by the position of the operating shaft 3-1 in the shifting gap 3-2, and when the operating shaft 3-1 is moved to a proper position in the shifting gap 3-2, the pedal damping force required by the driver can be obtained. The mode of moving the operating shaft 3-1 in the transposition gap 3-2 can be better operated by a driver, and is simple and convenient.

Therefore, when the operation shaft 3-1 moves into each opening in the transposition gap 3-2, the operation shaft 3-1 drives the damping element 2 to apply different pressures to the pedal assembly 1, the operation shaft 3-1 is switched among the openings through gaps, and the transposition baffle between the openings plays a limiting role. As shown in fig. 4, the shifting mechanism has two shift position changing gaps 3-2, which include two openings, namely a first opening and a second opening, a shifting baffle is disposed between the first opening and the second opening, a gap is disposed between the shifting baffle and the shift position adjusting plate, and the first opening, the gap, and the second opening sequentially form the shifting gap.

When a driver needs to adjust the damping of the pedal, the driver can press the press button 6 in the cab, the press button 6 controls the motor in the driving mechanism 4 through the control unit 5 to drive the rotating disc 4-1 to rotate around the rotating shaft 4-2 and move left and right, so that the operating shaft 3-1 is driven to move to a proper position in the transposition gap 3-2, and the damping force provided by the damping element 2 to the pedal assembly 1 meets the requirements of the driver.
