[0012] like Figure 1 As shown, it includes an anti-lock braking system 1, a bracket 2 and a shock absorbing assembly 3, wherein the shock absorbing assembly 3 is fixedly connected to the anti-lock braking system 1 through a support bolt 301, and the bracket 2 is provided with an opening structure and is installed in the groove of the shock absorbing pad 302 of the shock absorbing assembly 3. The other direction of the bracket 2 is fixed to the vehicle body according to the installation position of the whole vehicle.

[0013] like Figure 2 As shown, the shock absorbing assembly 3 includes a supporting bolt 301 and a shock absorbing pad 302 , and the supporting bolt 103 passes through the shock absorbing pad 104 and is installed on the anti-lock braking system 101 .

[0014] like Figure 3 As shown, the support bolt 301 includes a nut 30101, a mounting surface 30102, a mating surface 30103 and a fixing surface 30104, wherein the nut 30101 is located at the upper end and is used for installing and tightening the support bolt, the lower surface of the nut 30101 is the mounting surface 30102, the mounting surface is the plane of the shock absorber pad 302 compressed after installation, the mating surface 30103 is a cylindrical surface that passes through the mounting hole of the shock absorber pad 302 and cooperates with the shock absorber pad, and the fixing surface 30104 is the surface connected to the anti-lock braking system 1.

[0015] like Figure 3 As shown, the shock-absorbing pad 302 includes a mounting hole 30201, a mounting groove 30202 and a shock-absorbing ring band 30203, wherein the mounting hole 30201 cooperates with the support bolt to fix the shock-absorbing pad on the anti-lock braking system 1, and the mounting groove 30202 cooperates with the bracket 2 to install the anti-lock braking system 1 on the vehicle body through the bracket 2.

[0016] Working principle:

[0017] The shock-absorbing assembly 3 is the intermediate connecting part between the anti-lock braking system 1 and the bracket 2. When the whole vehicle vibrates, the vibration is transmitted to the shock-absorbing assembly through the bracket. The shock-absorbing pad 302 of the shock-absorbing assembly is deformed when subjected to external force. It stores a certain amount of elastic potential energy. When the external force disappears, the shock-absorbing pad 302 will return to its original shape and release the stored energy. This energy conversion process plays a role in shock absorption. By designing the width and number of the shock-absorbing ring belts 30203, the vibration influence of a specific frequency can be reduced or eliminated.
