[0030] In the related art, currently, the brake pedal and the booster fork of some traditional vehicles are connected by a pin shaft. Due to the clearance fit between the pin shaft and the mounting hole of the brake pedal swing arm, there is a problem of rebound abnormal noise between the brake pedal and the pin shaft, which seriously affects the riding experience of passengers.

[0031] The following references Figures 1 - 4Describe a brake pedal assembly according to an embodiment of the present utility model.

[0032] For the brake pedal assembly 100 according to the present utility model, the brake pedal assembly 100 includes: a brake pedal swing arm 11, a booster 12, and a pin shaft assembly 13. The pin shaft assembly 13 includes: a pin shaft and a shock-absorbing sleeve. The shock-absorbing sleeve is wrapped around the outer periphery of the pin shaft. A protruding portion 22 protruding from the shock-absorbing sleeve is formed on at least a part of the outer periphery of the shock-absorbing sleeve. The protruding portion 22 abuts against the brake pedal swing arm 11 to limit the movement of the brake pedal swing arm 11 relative to the brake pedal in a direction perpendicular to the pin shaft.

[0033] In some specific embodiments, a brake pedal swing arm 11, a booster 12, and a pin shaft assembly 13 are provided inside the brake pedal assembly 100. The pin shaft assembly 13 connects the brake pedal swing arm 11 and the booster 12 and restricts the brake pedal swing arm 11 and the booster 12 from separating from each other. The pin shaft assembly 13 is composed of a shock-absorbing sleeve and a pin shaft. A shock-absorbing sleeve is sleeved on the outer periphery of the pin shaft. A protruding portion 22 protruding away from the pin shaft is formed on at least a part of the outer periphery of the shock-absorbing sleeve. The protruding portion 22 can abut against the brake pedal to limit the movement of the brake pedal swing arm 11 relative to the brake pedal in a direction perpendicular to the pin shaft, thereby reducing the abnormal noise generated by the rebound between the brake pedal and the pin shaft and improving the riding experience of passengers.

[0034] The brake pedal assembly 100 according to the present utility model connects the brake pedal swing arm 11 and the booster 12 through the pin shaft assembly 13. A shock-absorbing sleeve is sleeved on the outer periphery of the pin shaft. A protruding portion 22 protruding away from the pin shaft is formed on at least a part of the outer periphery of the shock-absorbing sleeve. The protruding portion 22 can abut against the brake pedal to limit the movement of the brake pedal swing arm 11 relative to the brake pedal in a direction perpendicular to the pin shaft, thereby reducing the abnormal noise generated by the rebound between the brake pedal and the pin shaft and improving the riding experience of passengers.

[0035] According to some embodiments of the present utility model, a first limiting surface and a second limiting surface are formed on the booster 12. A mating hole is formed on the booster 12. The brake pedal swing arm 11 is received in the mating hole. A first mating portion and a second mating portion 232 are formed on the shock-absorbing sleeve and are spaced apart from each other. A protruding portion 22 is provided between the first mating portion and the second mating portion 232. The protruding portion 22 is adapted to cooperate with the brake pedal swing arm 11. The first mating portion and the second mating portion 232 respectively protrude from the protruding portion 22. The second mating portion 232 passes through the mounting hole of the booster 12. The first mating portion abuts against the first limiting surface, and the second mating portion 232 abuts against the second limiting surface to limit the movement of the booster 12 away from the brake pedal swing arm 11 in the axial direction, thereby improving the stability and reliability of the connection between the brake pedal swing arm 11 and the booster 12, and at the same time enhancing the stability and reliability of the pin shaft assembly 13 located inside the brake pedal swing arm 11 and the booster 12.

[0036] According to some embodiments of the present utility model, the shock-absorbing sleeve includes: a base 21, a convex portion 22, and a limiting portion 23. The base 21 is configured as a first mating portion, and at least a part of the outer periphery of the base 21 abuts against the first limiting surface; one end of the convex portion 22 in the axial direction is connected to the base 21, and the convex portion 22 is adapted to abut against the brake pedal swing arm 11. The limiting portion 23 is connected to the other end of the convex portion 22 in the axial direction. A protruding second mating portion 232 is formed on the outer periphery of one end of the limiting portion 23 facing the convex portion 22.

[0037] In some specific embodiments, the shock-absorbing sleeve is composed of a base 21, a convex portion 22, and a limiting portion 23. The first mating portion can be configured as the base 21. The convex portion 22 is disposed between the base 21 and the limiting portion 23. One side of the base 21 facing the convex portion 22 abuts against the first limiting surface to limit the movement of the booster 12 away from the brake pedal swing arm 11 in the axial direction. The outer periphery of the convex portion 22 protrudes away from the pin shaft direction and abuts against the brake pedal swing arm 11. A second mating portion 232 protruding away from the pin shaft direction is formed on the outer periphery of the limiting portion 23. The second mating portion 232 abuts against the second limiting surface to limit the movement of the booster 12 away from the brake pedal swing arm 11 in the axial direction, thereby improving the stability and reliability of the connection between the brake pedal swing arm 11 and the booster 12. At the same time, the stability and reliability of the pin shaft assembly 13 located in the brake pedal swing arm 11 and the booster 12 are improved.

[0038] According to some embodiments of the present utility model, a notch 101 extending in the axial direction is formed on the outer periphery of one end of the limiting portion 23 away from the convex portion 22, so that the limiting portion 23 can be deformed to a certain extent towards the notch 101. When the limiting portion 23 is inserted into the mounting hole provided on the brake pedal swing arm 11 and the mounting hole provided on the booster 12, it can conform to the shape of the holes of the mounting hole of the brake pedal swing arm 11 and the mounting hole of the booster 12 and deform moderately, thereby ensuring that the limiting portion cannot pass through the mounting hole of the brake pedal swing arm 11 and the mounting hole of the booster 12 and the convex portion 22 can closely fit the hole wall, reducing the assembly difficulty of the pin shaft assembly 13 with the mounting hole of the brake pedal swing arm 11 and the mounting hole of the booster 12, and improving the assembly efficiency of the pin shaft assembly 13 with the brake pedal swing arm 11 and the booster 12.

[0039] According to some embodiments of the present utility model, the limiting portion 23 is arranged at an interval from the pin shaft. The limiting portion 23 is connected to the protruding portion 22 and at least partially arranged at an interval, so that when the pin shaft assembly 13 is assembled with the brake pedal swing arm 11 and the booster 12, there is a certain deformation space between the limiting portion 23 and the pin shaft. The limiting portion 23 can deform towards the pin shaft, so that the second fitting portion 232 can pass through the mounting holes on the brake pedal swing arm 11 and the mounting holes on the booster 12 more simply, without additional alignment tools or complex manual operations, greatly simplifying the assembly process of the pin shaft assembly 13 with the brake pedal swing arm 11 and the booster 12 and improving the production efficiency.

[0040] According to some embodiments of the present utility model, a guiding inclined surface 231 is formed on the outer periphery of the end of the limiting portion 23 away from the protruding portion 22. The design of the guiding inclined surface 231 can make the assembly process between the pin shaft assembly 13 and the brake pedal swing arm 11 and the booster 12 smoother, facilitating the accurate placement of the pin shaft assembly 13 into the mounting holes of the brake pedal swing arm 11 and the fork of the booster 12. The inclined surface also helps to reduce the friction force when the pin shaft assembly 13 moves between the brake pedal swing arm 11 and the booster 12, thereby reducing the wear of the pin shaft assembly 13 and increasing the service life of the pin shaft assembly 13.

[0041] According to some embodiments of the present utility model, the guiding inclined surface 231 extends in a direction towards the axis of the pin shaft in the direction away from the base 21. When the second fitting portion 232 approaches the mounting hole of the brake pedal swing arm 11 and the mounting hole of the booster 12, the guiding inclined surface 231 can play a guiding role to help the second fitting portion 232 smoothly enter the hole, reducing the alignment difficulty during assembly and improving the assembly efficiency.

[0042] According to some embodiments of the present utility model, the connection between the guiding inclined surface 231 and the limiting portion 23 is configured as an arc surface. The design of the arc surface makes the transition between the guiding inclined surface 231 and the limiting portion 23 smoother, reducing the stress concentration at the connection point between the guiding inclined surface 231 and the limiting portion 23 and avoiding fatigue or fracture of the shock-absorbing sleeve caused by stress mutation. In addition, the connection between the guiding inclined surface 231 and the limiting portion 23 being configured as an arc surface can also reduce the sharp edges at the connection between the guiding inclined surface 231 and the limiting portion 23, thereby reducing the wear when the pin shaft assembly 13 is assembled with the brake pedal swing arm 11 and the booster 12 and extending the service life of the brake pedal assembly 100.

[0043] According to some embodiments of the present utility model, the diameter of the pin shaft gradually decreases in the axial direction towards the limiting portion 23. This design of the pin shaft can play a guiding role during the assembly process, making it easier to align and insert the pin shaft into the mounting hole on the brake pedal swing arm 11, reducing the assembly difficulty and assembly time of the pin shaft 14 assembly and the brake pedal swing arm 11, improving the assembly efficiency between the pin shaft 14 assembly and the brake pedal swing arm 11. In addition, during long-term use, the design of the pin shaft in this application can reduce the wear between the pin shaft and the shock-absorbing sleeve, improving the service life of the pin shaft assembly 13.
