Brake assembly for automobile door and automobile

Abstract

The invention discloses a brake assembly of a bus door. The brake assembly comprises a handle base and an outer handle which is rotatably connected to the handle base, and further comprises a brake device, wherein the brake device comprises a bracket which is fixedly connected to the handle base, and a brake block which is rotatably connected to the bracket through a rotary shaft; the brake block is mounted on the bracket through a return torsion spring and the rotary shaft extends in a vertical direction; under the action of side impact force, the brake block rotates to a brake position around one side, close to the outer handle, of the rotary shaft; on the brake position, the brake block is propped against the outer handle. According to the technical scheme adopted by the invention, under the impact of side impact force, the brake device blocks the outer handle from rotating, so that the error-opening of the bus door is prevented, and the brake is reliable; meanwhile, the brake device is not increased with the increase of the handle mass, so that the defects of the prior art are improved. The invention further provides a bus with the brake assembly.

Description

technical field [0001] The invention relates to the technical field of automobile accessories, in particular to a brake assembly of an automobile door. The invention also relates to a motor vehicle having the brake assembly described above. Background technique [0002] The outside handle of the car door is installed on the side of the car body. When the car is hit from the side, the impact force will generate an impact acceleration. To check and balance the impact acceleration, a counterweight with the same mass as the outside handle of the door is usually used. like Figure 1-2 As shown, the counterweight balance block 1 is installed on the outer door handle 2, and is respectively arranged on both sides of the shaft 3. When the outer door handle 2 is subjected to the impact acceleration α in the direction shown in the figure, the outer door handle 2 will produce a contact with the outer door handle 2 due to its own inertia. The first impact force F1 with the opposite impa...

Problems solved by technology

[0003] However, in the above-mentioned structure, there are the following defects: the weight of the counterweight balance weight 1 needs to increase with the increase of the mass of the outer door handle 2, when the mass of the outer door handle 2 increases or when the distance between the center of mass of the outer door handle 2 and the axis 3 is relatively small In the long run, the mass of the counterweight balance block 1 also increases, or even doubles, resulting in an increase in the mass of the vehicle, which is not convenient for the lightweight of the vehicle body
