[0022] In order to make the technical means, creation features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific drawings.

[0023] As shown in Figure 1 and Figure 2 , a low-wear brake pad with a buffer structure includes a back plate 1 and a brake pad 2 fixed to one side of the back plate 1, a plurality of buffer blocks 3 are arranged in the brake pad 2 to slide in the vertical direction, a plurality of buffer grooves 4 for the sliding of the buffer blocks 3 are formed in the brake pad 2, a plurality of elastic members 5 are fixed to the bottom of the buffer grooves 4, a connecting rod 6 is welded to the bottom of the buffer block 3, one end of the connecting rod 6 is connected to the elastic members 5, a limiting structure for limiting the horizontal movement of the buffer block 3 is arranged on the buffer block 3, and in this embodiment, the elastic member 5 is a spring.

[0024] When the brake system is started, first, the buffer block 3 is located outside the buffer groove 4, then, as the brake pad 2 moves towards the brake disc, one side of the buffer block 3 first abuts against the brake disc, as the brake pad 2 continues to approach the brake disc, the buffer block 3 moves in the buffer groove 4 towards the bottom of the buffer groove 4, at the same time, the connecting rod 6 also moves towards the bottom of the buffer groove 4, the spring is pressed by the connecting rod 6, so that the spring is compressed to generate elastic force, then, as the buffer block 3 moves until it is completely embedded in the buffer groove 4, the deceleration of the brake pad 2 can be completed. After the surface of the brake pad 2 completely adheres to the surface of the brake disc, the brake disc can be braked. Under the limiting action of the limiting structure, the buffer block 3 does not deviate in the horizontal direction, so that the buffer block 3 can be stably embedded in the buffer groove 4.

[0025] Through the structure of the present application, the buffer block 3 first contacts the surface of the brake disc, effectively reducing the violent rotation and vibration of the brake disc. When the surface of the brake pad 2 is in contact with the surface of the brake disc for braking, the rotation of the brake disc is relatively not intense, so that the wear and impact force on the surface of the brake pad 2 are reduced, the wear of the brake pad 2 is reduced, the service life of the brake pad 2 is increased, the problems of noise and vibration are reduced, and the stability and reliability of the braking are greatly improved. The adaptability to different road conditions and driving conditions is strong.

[0026] As shown in Figure 2 and Figure 3 , the bottom of the buffer groove 4 is provided with a sliding groove 9, and a plurality of elastic members 5 are fixed at the bottom of the sliding groove 9. The end of the connecting rod 6 close to the sliding groove 9 is welded with an abutting piece 11, and the side close to the elastic member 5 is fixedly connected with the plurality of elastic members 5.

[0027] When the buffer block 3 moves towards the bottom of the buffer groove 4 in the buffer groove 4, the connecting rod 6 and the abutting piece 11 move towards the bottom of the sliding groove 9. The abutting piece 11 makes the plurality of springs compressed to generate elastic force. The abutting piece 11 and one end of the connecting rod 6 are located in the sliding groove 9, and the other end of the connecting rod 6 and the buffer block 3 are located in the buffer groove 4.

[0028] When the brake pad 2 moves away from the brake disc, the buffer block 3 is not abutted, the spring is stretched to release the elastic force, and the abutting piece 11 is pushed to slide along the sliding groove 9 to the uppermost of the sliding groove 9. At the same time, the connecting rod 6 is located in the buffer groove 4, and the buffer block 3 moves out of the buffer groove 4.

When the buffer block 3 slides in the vertical direction in the buffer groove 4, the limiting rod 7 also slides in the vertical direction in the limiting groove 8, so as to limit the horizontal direction of the buffer block 3 during sliding into the buffer groove 4.

[0032] As shown in Figure 3 , the buffer block 3 is fixed with spring pieces 12 at both ends close to the bottom side of the buffer groove 4, and the bottom of the spring piece 12 is welded with the bottom of the buffer groove 4.

[0033] The spring sheet 12 can further enhance the damping effect. The spring sheet 12 can absorb and disperse more impact force, so that the overall damping performance is more superior, and the carrying capacity and stability of the buffer block 3 are significantly improved.

[0034] As shown in Figure 1 The brake pad 2 is provided with a heat dissipation groove 13 on one side.

[0035] The heat dissipation groove 13 can increase the air circulation effect when heat is generated by the friction between the brake pad 2 and the brake disc, thereby improving the heat dissipation performance of the brake system. On the other hand, a large amount of dust and debris will be generated by the friction between the brake pad 2 and the brake disc, and the heat dissipation groove 13 can be used for the discharge of dust and debris, thereby avoiding the accumulation of dust and debris on the friction surface, and maintaining the cleanliness and performance stability of the brake system.

[0036] As shown in Figure 1 The back plate 1 is integrally formed with a fixed plate 10 at both ends of one side, and the middle part of the two fixed plates 10 is provided with a positioning hole 14.

[0037] The positioning hole 14 can be used for positioning when the brake pad 2 is replaced, so that the brake pad 2 can be accurately installed on the caliper, and the position between the brake pad 2 and the brake disc is correct, which helps to maintain the stability and reliability of the brake system.
