For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0032] like Figures 1 to 3 As shown, in this embodiment, a pedal rebound assembly is used to assist in resetting the pedal mechanism after stepping on, comprising: a housing 1, a foot feeling mechanism 2 and a rebound mechanism 3; the housing 1 comprises: a sleeve portion 12 and a fixing portion 11, and the sleeve portion 12 can move on the fixing portion 11. The foot feeling mechanism 2 is arranged in the housing 1, and the foot feeling mechanism 2 is used to generate a damping force for the movement of the sleeve portion 12. The rebound mechanism 3 is arranged in the housing 1, and the rebound mechanism 3 is used to reset the pedal rebound assembly.

[0033] In the prior art, usually only a spring is used as the rebound force for the pedal to return to its original position. When the driver steps on the pedal too quickly, it is easy to trigger the emergency brake by mistake. In addition, the driver has a poor foot feel when stepping on such a pedal. The utility model provides a foot feel mechanism 2, which can provide a damping force for the movement of the sleeve portion 12. The damping force varies with the moving speed of the sleeve portion 12, which can effectively prevent the emergency brake triggered by stepping on the pedal too quickly, and at the same time produce different stepping foot feels to improve the driver's driving experience.

[0034] That is to say, the rebound assembly includes a shell 1, a foot-feeling mechanism 2 and a rebound mechanism 3. The foot-feeling mechanism 2 and the rebound mechanism 3 are both arranged in the shell 1. The shell 1 includes a sleeve portion 12 and a fixed portion 11. The sleeve portion 12 is slidably arranged on the fixed portion 11. When the driver steps on the pedal, the sleeve portion 12 slides on the fixed portion 11. The foot-feeling mechanism 2 provides a damping force in the opposite direction of the movement of the sleeve portion 12. The damping force changes with the speed of the movement of the sleeve portion 12. The rebound mechanism 3 generates a rebound force after the pedal is stepped on to reset the pedal.

[0035] It should be noted that the present application does not limit the specific structure of the foot feeling mechanism 2, and a reasonable selection can be made according to the specific situation, as long as the damping force that generates the movement of the sleeve portion 12 can be achieved.

[0036] Specifically, Figure 3As shown, in this embodiment, the foot-sensing mechanism 2 includes: a main body 21 and an output part 22; the main body 21 is located in the fixing part 11, and the output part 22 is located in the sleeve part 12. The foot-sensing mechanism 2 is a hydraulic actuator or a pneumatic actuator.

[0037] That is to say, the foot feeling mechanism 2 includes a main body 21 and an output part 22. The main body 21 is located in the fixed part 11 of the shell 1, and the output part 22 is located in the sleeve part 12 of the shell 1. Specifically, the pneumatic actuator can be a cylinder. By passing a certain air pressure into the cylinder, the sleeve part 12 generates a damping force when moving. At the same time, the faster the movement speed of the sleeve part 12, the greater the damping force, thereby achieving the purpose of generating a pedal feeling and avoiding triggering emergency braking.

[0038] In addition, the hydraulic actuator can be a hydraulic cylinder. By introducing a certain amount of liquid into the hydraulic cylinder, the sleeve part 12 generates a damping force when moving. At the same time, the faster the sleeve part 12 moves, the greater the damping force, thereby achieving the purpose of generating a pedaling feeling and avoiding triggering emergency braking.

[0039] Specifically, Figures 1 to 3 As shown, in this embodiment, a first connecting ring 231 is provided at one end of the main body 21, and a first connecting portion 131 is provided at one end of the fixing portion 11, and the first connecting portion 131 includes: at least two first fixing plates; a first mounting hole is opened on one end surface of the fixing portion 11, and the first mounting hole is located between adjacent first fixing plates, and the first connecting ring 231 passes through the first mounting hole;

[0041] That is, a first connecting ring 231 is provided at the outer end of the body 21, a first connecting portion 131 is provided at the outer end of the fixing portion 11, the first connecting portion 131 includes at least two first fixing plates arranged in parallel, a first mounting hole is opened at the outer end of the fixing portion 11, the first mounting hole is arranged between adjacent first fixing plates, the first connecting ring 231 at one end of the body 21 can pass through the first mounting hole, and the pedal rebound assembly can be connected to the pedal mechanism through the first connecting ring 231 and the first connecting portion 131;

[0042] A second connecting ring 232 is provided at the outer end of the output portion 22, and a second connecting portion 132 is provided at the outer end of the sleeve portion 12. The second connecting portion 132 includes at least two second fixing plates arranged in parallel. A second mounting hole is opened at the outer end of the sleeve portion 12. The second mounting hole is arranged between adjacent second fixing plates. The second connecting ring 232 at one end of the output portion 22 can pass through the second mounting hole. The pedal rebound assembly can be connected to the pedal mechanism through the second connecting ring 232 and the second connecting portion 132.

[0043] It should be noted that the present application does not limit the specific structure of the rebound mechanism 3, and a reasonable selection can be made according to the specific situation. The rebound mechanism 3 can be deformation rebound, external force rebound and spring rebound, as long as it can achieve the reset of the pedal after stepping on it.

[0044] Furthermore, if Figure 3 As shown, in this embodiment, the rebound mechanism 3 includes: a sliding portion 31, a first rebound portion 32 and a second rebound portion 33; the sliding portion 31 is slidably arranged between the fixed portion 11 and the main body 21, and the fixed portion 11 is provided with an extension portion 34 on the side close to the sleeve portion 12, and the extension portion 34 can move between the fixed portion 11 and the sleeve portion 12. A positioning sleeve 14 is provided in the sleeve portion 12, and the two ends of the first rebound portion 32 are respectively sleeved on the extension portion 34 and the positioning sleeve 14, and one end of the first rebound portion 32 is pressed against one side of the sliding portion 31. The second rebound portion 33 is arranged between the fixed portion 11 and the main body 21, and one end of the second rebound portion 33 is pressed against one side of the sliding portion 31.

[0045] In other words, the rebound mechanism 3 includes a sliding portion 31, a first rebound portion 32 and a second rebound portion 33. The sliding portion 31 is arranged between the fixed portion 11 and the main body 21, and can slide between the fixed portion 11 and the main body 21. An extension portion 34 is provided on the side of the sliding portion 31 close to the sleeve portion 12. The extension portion 34 is in a circular ring shape. A positioning sleeve 14 is provided on the inner side of one end of the sleeve portion 12. One end of the first rebound portion 32 is sleeved on the outer side of the extension portion 34, and the other end is sleeved on the positioning sleeve 14. The second rebound portion 33 is arranged between the fixed portion 11 and the main body 21. One end of the second rebound portion 33 is pressed against the sliding portion 31, so that the sliding portion 31 is at one end of the fixed portion 11 and the extension portion 34 is in the sleeve portion 12.

[0046] Furthermore, when stepping on the pedal, the sleeve portion 12 first slides on the fixed portion 11 to compress the first rebound portion 32. When the first rebound portion 32 is compressed to a certain extent, the rebound force of the first rebound portion 32 pushes the sliding portion 31 to move, thereby compressing the second rebound portion 33 until the pedal is stopped.

[0047] A pedal comprises a main body and a pedal rebound component arranged in the main body.

[0048] A car comprises a car body and a pedal arranged in the car body.

[0049] In general, the present application provides a pedal rebound assembly. When stepping on the pedal, the sleeve portion 12 first slides on the fixed portion 11, compressing the first rebound portion 32 and causing the output portion 22 of the foot feel mechanism 2 to contract. The output portion 22 generates a damping force during the contraction process to slow down the movement speed of the sleeve portion 12, thereby generating the feeling of stepping on the pedal. The damping force increases with the increase in the movement speed of the sleeve portion 12, thereby avoiding emergency braking triggered by stepping on the pedal too quickly. When the first rebound portion 32 is compressed to a certain extent, the rebound force of the first rebound portion 32 will push the sliding portion 31 to move, causing the second rebound portion 33 to be compressed until the pedal is stopped.
