Technical Field
[0001] The utility model relates to the technical field of automobile brakes, and in particular to a new energy automobile brake. Background Art

The friction element clamps the brake disc from both sides to produce braking. There are many structural forms of fixed elements, and disc brakes can be roughly divided into two categories: caliper disc type and full disc type.
[0003] During the use of existing disc brakes, the brake disc and brake pad may be damaged due to contact vibration between the brake disc and the brake pad, and the brake disc may overheat due to high friction.

When the car is parked for too long, the sensor sends information to the small hydraulic press through sensing, so that the small hydraulic press runs, and then the hydraulic rod moves left and right, thereby squeezing and moving the brake disc, so that the brake disc contacts the third brake pad, and the brake disc is parked. The phenomenon of car deviation caused by the user not pulling the handbrake when the car is parked is reduced, thereby reducing safety accidents caused by not pulling the car handbrake and increasing the safety of the car; its defect is that the brake in this scheme only buffers the vibration caused by the contact between the brake disc and the third brake pad through the shock-absorbing spring, and the effect is poor. Therefore, it is particularly important to improve the existing automobile brakes and design a new type of new energy automobile brake to solve the above technical defects and improve the practicality of the overall automobile brake.

[0025] The buffer assembly 5 is used for buffering the second brake pad 4 .
[0026] Furthermore, the buffer assembly 5 is composed of a accommodating block 8, a first arc-shaped piece 9, a second arc-shaped piece 10, a first elastic ball 11, a fixing block 12 and a second elastic ball 13.

When the first arc-shaped piece 9 is deformed by pressure, its interior is compressed. At this time, the internal air cooperates with the second arc-shaped piece 10 to gradually overflow through the through groove 14, so that the first arc-shaped piece 9 gradually deforms and collapses before the pressure is removed, so as to absorb the pressure energy to provide damping and buffering for the pressure-applying component, and at the same time, the second arc-shaped piece 10 can be driven to move, so that the first elastic ball 11 can be moved.
