[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other in any way.

[0023] In existing automotive brakes, the circlip must be mounted on the brake bracket. During normal vehicle operation, especially at high speeds and during emergency braking, the circlip is susceptible to vibration and impact, causing it to loosen or even fail, impacting the stability of the braking system and driving safety. To prevent this loosening, traditional circlip designs are complex or require additional tools for installation, increasing assembly complexity, extending production time, and reducing efficiency.

[0024] Based on this, an exemplary embodiment of the present application provides a self-locking automobile brake with a retaining spring, in which a limiting portion is formed on the brake bracket, and a limiting slot is formed on the limiting portion. The retaining spring includes a retaining spring body and a self-locking arm, and the self-locking arm is clamped in the limiting slot, which can realize rapid installation between the retaining spring and the brake bracket, and the installation steps are simple and quick; at the same time, the self-locking arm of the retaining spring can form a self-locking structure with the limiting slot, so that a stable connection is formed between the retaining spring and the brake bracket, which can prevent the retaining spring from falling off and loosening.

[0025] An exemplary embodiment of the present application provides a self-locking automobile brake of a circlip, such as Figures 1 to 3As shown, the brake includes a brake bracket 10 and a retaining spring 20; the retaining spring 20 is installed at both ends of the inner side of the brake bracket 10, and the retaining spring 20 includes a retaining spring body and a self-locking arm 201, and the self-locking arm 201 is tilted on the retaining spring body close to the side of the brake bracket 10, and the opening between the self-locking arm 201 and the retaining spring body is set toward the center of the brake bracket 10; preferably, the retaining spring body and the self-locking arm 201 are formed in one piece; the brake bracket 10 is preferably made of high-strength steel, which has good mechanical properties and corrosion resistance, and a limiting portion 101 is formed at both ends of the inner side of the brake bracket 10; the brake bracket Mounting grooves 103 are formed at both ends of the inner side of the frame 10, and the opening of the mounting groove 103 is arranged toward the interior of the brake bracket 10; the limiting portion 101 is arranged at the upper part of the mounting groove 103 and a limiting slot 102 is formed on the limiting portion 101; the self-locking arm 201 is clamped in the limiting slot 102, which can realize the rapid installation between the retaining spring 20 and the brake bracket 10, and the installation steps are simple and fast; at the same time, the self-locking arm 201 of the retaining spring 20 can form a self-locking structure with the limiting slot 102, so that a stable connection is formed between the retaining spring 20 and the brake bracket 10, which can prevent the retaining spring 20 from falling off and loosening.

[0026] In one embodiment, if Figure 5 As shown, the retaining spring body includes a first mounting portion 203 and a second mounting portion 204. The upper portions of the first mounting portion 203 and the second mounting portion 204 are connected as a whole by a connecting portion 205. The first mounting portion 203, the second mounting portion 204, and the connecting portion 205 are integrally formed. Preferably, the first mounting portion 203 and the second mounting portion 204 are each provided with a self-locking arm 201 and a blocking arm 202. The blocking arm 202 is disposed on the side of the retaining spring body and extends toward the end of the brake bracket 10. The blocking arm 202 is integrally formed with the retaining spring body. Preferably, the blocking arm 202 is disposed on the inner side of the first mounting portion 203 and the second mounting portion 204. The blocking arm 202 is close to the end surface of the limiting portion 101 of the brake bracket 10 to prevent the retaining spring 20 from falling out of the limiting slot 102.

[0027] The first mounting portion 203 and the second mounting portion 204 each include a first section 206, a second section 207, and a third section 208, which are connected in sequence. The first section 206 is connected to the connecting portion 205, and the third section 208 is disposed within the mounting groove 103. The second section 207 protrudes from the first and second sections 206, 207 toward the center of the brake bracket 10 to conform to the shape of the brake bracket 10, ensuring a tight fit between the retaining spring 20 and the brake bracket 10 and improving stability. The self-locking arm 201 and the blocking arm 202 are both disposed on the second section 207.

[0028] In one embodiment, if Figure 3As shown in Figure 4, the brake bracket 10 also includes a guide pin mounting seat 104 having a guide pin mounting hole formed therein; a guide pin dust cover is mounted in the guide pin mounting hole; and a guide pin is mounted in the guide pin dust cover. The guide pin dust cover converts the vibration energy generated during braking into heat and dissipates it, thereby suppressing resonance of the brake bracket 10 and improving brake stability. A buffer pad mounting seat 105 is formed on the side of the guide pin mounting seat 104 opposite the guide pin mounting hole. A spring element is sleeved on the buffer pad mounting seat 105 and a buffer pad is mounted thereon. The spring element is preferably a spring. The spring element and buffer pad absorb and dissipate the impact force and vibration energy generated during braking, effectively preventing vibration from being transmitted to the vehicle body or suspension system, and reducing noise caused by vibration.

In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the article or device comprising the element.

[0030] Although the preferred embodiments of the present application have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.
