[0036] The frame 1 includes: a central axis 12 and a limit plate 11, one end of the foot pedal 2 is rotatably connected to the central axis 12, and the limit plate 11 is used to limit the rotation angle of the foot pedal 2. The rebound component is arranged on the frame 1, and the rebound component is used to reset the foot pedal 2 after being stepped on. The detection component is located on the central axis 12 or on the limit plate 11, and the detection component is used to detect the reset state of the foot pedal 2.

[0037] In a conventional pedal, multiple springs are responsible for resetting the pedal. After the pedal is used for a long time, the springs in the pedal will age. The aging of a single spring does not affect the pedal's resetting to the initial position, but it will lead to insufficient resetting rebound force, so that the car mistakenly recognizes that the pedal is always in a stepped state, affecting the safety of the car's driving. The utility model arranges a detection component on the central axis 12 or the limit plate 11. The detection component can detect the elastic force of the rebound component during the pedal resetting process, and judge the state of the rebound component by the size of the elastic force, so as to facilitate the timely maintenance of the rebound component in the pedal and ensure the driving safety of the car.

[0038] The pedal assembly includes a frame 1, a foot pedal 2, a rebound assembly and a detection assembly. The frame 1 includes a central axis 12 and a limit plate 11. One end of the foot pedal 2 is located in the frame 1 and is connected to the central axis 12, so that the foot pedal 2 and the central axis 12 rotate synchronously. The limit plate 11 is located in the rotation direction of the foot pedal 2 and can limit the rotation angle of the foot pedal 2. The rebound assembly is arranged on the frame 1 and is located in the rotation direction of the foot pedal 2. The foot pedal 2 can be rebounded and reset by the rebound assembly. The detection assembly can be arranged on the central axis 12 or the limit plate 11. The detection assembly determines the state of the rebound assembly by detecting the rebound force of the rebound assembly in the reset state of the foot pedal 2, thereby determining whether the rebound assembly needs to be replaced or maintained.

[0039] The reset state that can be detected by the detection component includes the pressure of the foot pedal 2 on the limit plate 11 and the torque of the central shaft 12 to confirm the resilience of the rebound component.

The detection component can also be a pressure sensor 32; the pressure sensor 32 is located on the limit plate 11, and the detection end of the pressure sensor 32 is arranged toward the pedal 2.

[0041] When the detection component is a torque sensor 31, the torque sensor 31 is arranged on the central shaft 12, and the torque of the central shaft 12 when it is reset is detected to determine whether the state of the rebound component is abnormal. When the detection component is a pressure sensor 32, the pressure sensor 32 is arranged on the limit plate 11, and the pressure sensor 32 can detect the pressure generated by the foot pedal 2 on the limit plate 11 when it is reset, and determine whether the state of the rebound component is abnormal by the pressure.

[0042] like Figures 1 to 3 As shown, in this embodiment, the cross section of the foot pedal 2 is arc-shaped, and the foot pedal 2 is provided with a treading surface, and the treading surface is located at one end outside the frame 1. The foot pedal 2 is provided with an extension portion 22, and the extension portion 22 is located at one end inside the frame 1. The frame 1 is provided with a limit block 13, and the extension portion 22 can move between the limit plate 11 and the limit block 13.

[0043] The foot pedal 2 is generally arc-shaped, and a treading surface is provided at one end of the foot pedal 2 for the driver to step on the foot pedal 2. An extension portion 22 is provided at the other end of the foot pedal 2. The extension portion 22 is located in the frame 1. A limit block 13 is provided on the frame 1. The limit block 13 is arranged at a position corresponding to the extension portion 22, so that the extension portion 22 can only move between the limit plate 11 and the limit block 13, thereby limiting the degree of stepping on the pedal assembly.

[0044] The present application does not limit the specific structure of the rebound component, and a reasonable selection can be made according to actual conditions. The rebound component can be pneumatic rebound, hydraulic rebound or spring rebound, as long as the foot pedal 2 can be reset.

A positioning sleeve 21 is provided on one side of the foot pedal 2. The positioning sleeve 21 is arranged corresponding to the position of the sleeve portion 42. The first end of the second rebound portion 43 is arranged in the positioning sleeve 21. The second end of the second rebound portion 43 is arranged in the sleeve portion 42. The third connecting end is rotatably connected to the first end of the first rebound portion 44. The second end of the first rebound portion 44 is rotatably connected to the frame 1. The third rebound portion 45 is arranged on the frame 1. The third rebound portion 45 is arranged corresponding to the movement direction of the sleeve portion 42.

[0047] When stepping on the pedal 2, the pedal 2 rotates around the central axis 12, and the pedal 2 will compress the second rebound part 43, while causing the transmission part 41 to rotate around the central axis 12, thereby compressing the first rebound part 44. As the rotation angle of the pedal 2 becomes larger and larger, the bottom of the sleeve part 42 will compress the third rebound part 45. After the pedal 2 stops being stepped on, the pedal 2 is reset by the rebound force of the first rebound part 44, the second rebound part 43 and the third rebound part 45.

[0049] A signal plate 5 is provided on one side of the frame 1, and one end of the signal plate 5 is connected to the central axis 12, so that the signal plate 5 can rotate synchronously with the central axis 12, thereby making the signal plate 5 rotate synchronously with the pedal 2, a first magnetic portion 51 is provided at a first end of the signal plate 5, and a second magnetic portion 52 is provided at a second end of the signal plate 5, and a signal of a rotation angle is transmitted through the first magnetic portion 51 and the second magnetic portion 52, and a Hall sensor is provided on the frame 1, and the Hall sensor can identify the signals transmitted by the first magnetic portion 51 and the second magnetic portion 52 and can output the signals to the vehicle.

[0050] like Figures 1 to 3 As shown, in this embodiment, the pedal assembly further includes: a prompt unit; the prompt unit is used to issue a prompt message when the detection component detects that the reset state of the pedal is abnormal.

[0051] A car comprises a car body and the pedal assembly arranged in the car body.

[0052] In general, the present application provides a pedal assembly. When the driver steps on the pedal 2, the pedal 2 rotates with the central axis 12 as the center of the circle. The pedal 2 compresses the second rebound portion 43 and makes the transmission portion 41 rotate with the central axis 12 as the center of the circle, thereby compressing the first rebound portion 44. As the rotation angle of the pedal 2 increases, the bottom of the sleeve portion 42 compresses the third rebound portion 45. After the pedal 2 stops being stepped on, the pedal 2 is reset by the rebound force of the first rebound portion 44, the second rebound portion 43 and the third rebound portion 45. The reset state of the pedal 2 is detected by the detection assembly. When the detection assembly is a torque sensor 31, the torque sensor 31 determines whether the state of the rebound assembly is abnormal by detecting the torque of the rotation of the central axis 12. When the detection assembly is a pressure sensor 32, the pressure of the pedal 2 on the pressure sensor 32 at the initial position is detected to determine whether the state of the rebound assembly is abnormal. When the state of the rebound assembly is abnormal, the prompt unit can remind the driver.
