Description

Technical Field

[0001] This utility model belongs to the field of brake pedal assembly, and in particular to a brake pedal with an anti-slip structure. Background Technology

[0002] Currently, brake pedal assemblies mainly consist of components such as pedal brackets, pedal arm assemblies, central shafts, bushings, and pedal arm return springs. The shaft end of the pedal arm assembly is interference-fitted with the bushing on the central shaft for fixation. However, the existing connection method has a risk: if the fit between the pedal arm assembly and the bushing fails, the pedal bracket assembly, lacking a limiting mechanism, can cause the pedal arm assembly to slip off, resulting in complete brake failure. Further explanation of pedal arm assembly slippage: To ensure the pedal arm assembly returns to its normal position, it is essential to prevent the connection between the two feet of the pedal arm return spring from detaching. In existing products, bushing failure causes the pedal arm assembly to slide axially on the bushing, leading to one foot of the pedal arm return spring detaching from the connection, resulting in brake failure due to the failure of the pedal arm return spring. Utility Model Content

[0003] This invention proposes a brake pedal with an anti-slip structure, which aims to solve the problem of slippage of the pedal arm assembly due to bushing failure.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a brake pedal with an anti-slip structure, mainly including a pedal bracket, a pedal arm assembly, a central shaft, a pedal arm return spring, and a bushing. The bushing is connected to the pedal bracket through the central shaft. The shaft tube end of the pedal arm assembly is interference-fitted with the bushing. The pedal arm assembly can rotate on the central shaft through the bushing. The pedal arm return spring is fitted on the shaft tube end of the pedal arm assembly. The first hook of the pedal arm return spring is connected to the pedal arm in the pedal arm assembly. The characteristic is that: the pedal bracket can limit the second hook of the pedal arm return spring, restricting the second hook from sliding along the bushing axis.

[0005] Further defining the above technical solution, the pedal support structure includes a central shaft support, which is frame-shaped. From the outside inwards, the front end of the central shaft support is sequentially provided with a first reinforcing part, a foot-hanging limiting part, and a transition platform. The top surface of the first reinforcing part has a countersunk bolt cavity, and a columnar body extends outwards from the back of the first reinforcing part. The columnar body has bolt through holes. Axle holes are provided on the opposing cavity walls at the front end of the central shaft support, located above the foot-hanging limiting part. A second reinforcing part is provided at the bottom of the rear end of the central shaft support, connected to the transition platform. Multiple bolt holes are distributed on the second reinforcing part. The central shaft support, the first reinforcing part, the foot-hanging limiting part, the second reinforcing part, and the transition platform are a single unit.

[0006] Further defining the above technical solution, the structure of the foot-mounting limiting part includes a base, the base being in a concave arc shape, a limiting protrusion on the support surface of the base, a reinforcing rib on the back of the base, and the base being connected to the first reinforcing part as a whole through the reinforcing rib.

[0007] A further improvement to the above technical solution is that the pedal bracket is provided with a lower limit bracket, the lower limit bracket has a limit groove at its limit end, the pedal arm assembly is provided with an upper limit bracket, the upper limit bracket has a limit block at its limit end, and the limit block is slidably connected to the limit groove.

[0008] Beneficial effects: This utility model adds a foot-hanging limiting structure to the pedal bracket, so that when the pedal arm assembly fails and slips out, the pedal arm assembly will wobble more due to the limiting structure of the pedal bracket assembly, but it will not slip out, and the pedal braking can continue to be achieved; This utility model has a simple structure, low production cost, and effectively solves the risk of the brake pedal losing braking due to bushing failure.

[0013] like Figure 1 As shown, a brake pedal with an anti-slip structure mainly includes a pedal bracket 1, a pedal arm assembly 2, a central shaft 3, a pedal arm return spring 4, and a bushing 5. The bushing is connected to the pedal bracket through the central shaft. The shaft tube end of the pedal arm assembly is interference-fitted with the bushing. The pedal arm assembly can rotate on the central shaft through the bushing. The pedal arm return spring is fitted on the shaft tube end of the pedal arm assembly. The first hook of the pedal arm return spring is connected to the pedal arm in the pedal arm assembly. The pedal bracket can limit the second hook 401 of the pedal arm return spring, restricting the second hook from sliding along the bushing axis.

[0014] like Figure 2 and Figure 3As shown, the pedal bracket 1 further comprises a central shaft bracket 101, which is frame-shaped. From the outside inwards, the front end of the central shaft bracket is sequentially provided with a first reinforcing part 102, a foot-hanging limiting part 103, and a transition platform 104. The top surface of the first reinforcing part has a countersunk bolt cavity 105. A columnar body 106 extends outwards from the back of the first reinforcing part, with a bolt through hole 107 inside the columnar body. A shaft hole 108 is provided on the cavity walls opposite to the front end of the central shaft bracket, located above the foot-hanging limiting part. A second reinforcing part 109 is provided at the bottom of the rear end of the central shaft bracket, connecting to the transition platform. Multiple bolt holes 110 are distributed on the second reinforcing part. The central shaft bracket, the first reinforcing part, the foot-hanging limiting part, the second reinforcing part, and the transition platform are cast as a single unit. This structure ensures the strength of the pedal bracket while achieving lightweight design, which helps reduce production costs.

[0015] like Figure 2 and Figure 3 As shown, the structure of the foot limiting part further includes a base 1031, which is in the shape of a concave arc. A limiting protrusion 1032 is provided on the support surface of the base, and a reinforcing rib 1033 is provided on the back of the base. The base is connected to the first reinforcing part as a whole through the reinforcing rib. This structure not only ensures the strength of the limiting part, but also achieves lightweighting, which is conducive to reducing production costs.

[0016] like Figure 4 As shown, the pedal bracket is further provided with a lower limit bracket 6, and the lower limit bracket has a limit groove 7 at its limit end. The pedal arm assembly is provided with an upper limit bracket 8, and the upper limit bracket has a limit block 9 at its limit end. The limit block and the limit groove are slidably connected. When the brake pedal is not in use, the cooperation between the limit block and the limit groove can further prevent the pedal arm assembly from shaking or making abnormal noise due to vibration.
