Description

Anticollision dish is stopped

Technical Field

The invention relates to the technical field of brake accessories of non-motor vehicles, in particular to an anti-collision disc brake.

Background

The bicycle and the electric bicycle are more and more widely used as walking tools for people to go out due to low price, flexible running and simple driving technology. The brake device is an indispensable safety part of bicycles and electric bicycles, and the reliability and the sensitivity of the operation of the brake device are directly related to the life safety of people.

At present, a disc brake is divided into a mechanical disc brake and an oil pressure disc brake, and the mechanical disc brake is to rub a brake pad in a caliper and clamp a disc by the pulling force of a brake cable to generate a braking effect. The mechanical disc brake is popular due to the compatibility convenience, easy installation and low later maintenance cost; therefore, the disc brake rocker arm and the fastening part thereof protrude out of the disc brake main body and directly impact the disc brake rocker arm or the rocker arm fastening part when the vehicle falls down or turns over, so that the disc brake rocker arm is deformed or an internal driving mechanism connected with the disc brake rocker arm is damaged, and the brake failure is seriously caused.

For example, in CN201721706699.9 electric vehicle disc brakes and electric vehicles, the protection disc is arranged to prevent an external object from impacting the disc brake sheet, and an external foreign object can impact the disc brake sheet to deform the disc brake sheet. As for the CN202022248974.5 automobile disc brake, the overall strength and the wear resistance are improved by arranging the high-strength layer, and the anti-collision strength of the disc brake is improved when the disc brake is collided; the structure improves the anti-collision performance of the disc brake, but the structure and the production process are complex, and the overall cost is increased.

Therefore, it is highly desirable to provide a disc brake with a novel anti-collision structure to overcome the above problems.
