The above description is simplified for the convenience of describing the present invention, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all drawings, the same reference numerals represent the same or functionally identical elements.
[0021] refer to Figure 1The automobile brake caliper of the circlip bracket structure is mainly composed of a caliper support 10 and a piston caliper 20 that match and slide together. The piston caliper 20 reciprocates and slides parallel to the axis of the brake disc 1 with the caliper support 10 as a base, and cooperates with the brake pads 2 respectively fixed on the piston caliper 20 and the caliper support 10 and located on both sides of the brake disc 1 to achieve the braking function of the vehicle. In order to reduce quality and manufacturing costs, the caliper support 10 is a single-sided base, that is, its outer part is designed to be an open, open structure.
[0022] refer to Figure 2 During the driving of the vehicle, the brake disc 1 rotates at a high speed, and the piston caliper 20 is prone to instability during the reciprocating movement. That is, the piston caliper 20 is prone to slight rotation around the longitudinal axis, so a circlip bracket 30 is added to the front end of the piston caliper 20 and the caliper support 10 to ensure the relative position between the two and ensure that the piston caliper 20 moves along a predetermined trajectory. The circlip bracket 30 is clamped on the inner side of the tongue 21 through a pair of pins 34 on the upper part of its main body 31.
[0023] Combined with reference Figure 3 Specifically, a bent convex bump 35 is provided at the end of the pin portion 34, and the convex bump 35 is clamped on the piston caliper 20 to achieve convenient installation. Furthermore, the convex bump 35 and the main body 31 are integrally formed to ensure strength. A fixing hole 36 is provided at the bottom of the main body 31. After the clamping installation is completed, the circlip bracket 30 is firmly connected to the piston caliper 20 through the fixing hole 36 and the fastener.
[0024] Combined with reference Figure 4 A pressure foot 33 is provided at both longitudinal ends of the main body 31, and the extension direction of the pressure foot 33 is parallel to the moving trajectory direction of the piston caliper 20, so that the pressure foot 33 is close to the lower end surface 12 of the outer frame 11 of the caliper support 10 when the piston caliper 20 moves, forcing the distance between the front side of the piston caliper 20 and the lower end surface 12 to remain relatively unchanged, so that the moving trajectory of the piston caliper 20 is always parallel to the wheel axle.
[0025] In addition, a leaf spring structure 32 is connected between the presser foot 33 and the main body 31 . The leaf spring structure 32 is an arc-shaped leaf spring, which enables the presser foot 33 to have elastic recovery performance and ensures that the presser foot 33 is tightly fitted with the lower end surface 12 .
