When you step on the brake, it clamps the brake disc to slow down or stop the car. The brake disc has a good braking effect and is easier to maintain than drum brakes. At the same time, the brake disc is also an important component of electric vehicles.

[0003] For example, the utility model with the publication number CN217481809U discloses a brake disc structure for electric vehicles, including a brake disc body, the brake disc body is provided with a through hole, the inside of the brake disc body is provided with a weight reduction groove located on one side of the mounting hole, and one end of the brake disc body is provided with a limiting mechanism located on the outside of the mounting hole. The utility model sets a limiting mechanism, and when the mounting hole is aligned with the threaded sleeve at one end of the wheel hub, the brake disc body is pressed so that the arc-shaped limiting plate is located on the outside of the threaded sleeve, thereby limiting the left and right movement direction of the brake disc body, and at the same time, the friction pad is used to limit the front and rear movement of the brake disc body relative to the threaded sleeve. After that, when the brake disc body is fixed by bolts, the brake disc body cannot rotate relative to the wheel hub, thereby increasing the stability of the installation of the brake disc body and also improving the installation efficiency.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 4 As shown, the utility model provides a brake disc assembly for a small electric vehicle, including a brake plate 1, a positioning ring 2 is fixedly installed in the middle of the surface of the brake plate 1, a plurality of through grooves are opened in the middle of the positioning ring 2, and limiting rods 3 are fixedly installed at the four corners of the through grooves, a plurality of mounting grooves are opened in a circular array at equal intervals on the surface of the brake plate 1, a buffer assembly 4 is fixedly installed in the mounting groove, a mounting plate 5 is fixedly installed on the back of the brake plate 1, and an air guide assembly 6 is fixedly installed on the surface of the mounting plate 5.

[0024] During the braking process, the brake plate 1 will drive the limit tube 41 to move. When the limit tube 41 moves, it will drive the resistance block 44 to contact the wheel. After the resistance block 44 contacts the wheel, the damping rod 42 and the spring 43 on the back of the resistance block 44 will buffer the extrusion and buffer the wheel braking. During the braking process, the outside air will enter the interior of the sealing ring 61 through the air duct 62. After entering the interior of the sealing ring 61, the air will flow to the back of the brake plate 1 through the storage ring 63. After flowing, it will flow out through the gap between the brake plate 1 and the wheel to dissipate the heat energy generated by the brake.

[0025] like Figures 1 to 4 As shown, the buffer assembly 4 includes a limiting tube 41 fixedly installed inside the mounting groove, a damping rod 42 is fixedly installed inside the limiting tube 41, a spring 43 is sleeved on the surface of the damping rod 42, a resistance block 44 is fixedly installed at one end of the damping rod 42, the surface of the resistance block 44 is in contact with the wheel, a wear-resistant plate is fixedly installed at one end of the resistance block 44, the size of the wear-resistant plate is adapted to the size of one end of the resistance block 44, and the wear-resistant plate is in contact with the surface of the wheel.

[0026] During use, the brake plate 1 drives the limiting tube 41 to move. When the limiting tube 41 moves, it will drive the resistance block 44 to contact the wheel. After the contact, the spring 43 on the damping rod 42 will be squeezed, and then the spring 43 will rebound and reset the resistance block 44 through the damping rod 42, thereby hindering the movement of the brake plate 1, reducing the situation where the brake plate 1 directly contacts the wheel when people brake suddenly, causing the electric vehicle to overturn, thereby improving the safety during driving.

The size of the positioning groove is adapted to the size of the air guide duct 62. The air guide duct 62 passes through the storage ring 63, and a mounting groove is provided inside the air guide duct 62. A filter net is embedded in the mounting groove, and the size of the filter net fits the inner wall of the air guide duct 62. The surface of the sealing ring 61 is connected to the back of the brake plate 1, and a rubber ring is provided at the connection between the sealing ring 61 and the brake plate 1.

[0028] During use, the mounting plate 5 will drive the sealing ring 61 to rotate. When the sealing ring 61 rotates, the outside air will be introduced into the air duct 62. The air inside the air duct 62 will be blown toward the back of the brake plate 1 through the storage ring 63, dissipating the heat energy generated by the brake plate 1 when braking, thereby increasing the service life of the brake plate 1.
