Fig. 3 is a schematic view of the matching of the housing and the brake pad of the present invention.

The brake pad comprises a shell 1, a rotating shaft 2, a first section 21, a second section 22, a housing 3, a brake pad 4, a protruding portion 5, a groove 6, a notch 7, a mounting column 8, a connecting portion 9, a positioning hole 10, a mounting seat 11, a worm 12 and a worm wheel 13.

Detailed Description

The invention will be further explained with reference to the following embodiments and drawings:

in the embodiment, as shown in fig. 1, fig. 2, fig. 3, brake motor, including casing 1 and

pivot

2, 2 parts of pivot are located the outside of casing 1 bottom, housing 3 is installed to the bottom of casing 1, be equipped with in the housing 3 with 2 interference fit's of pivot brake block 4, the inner wall of housing 3 is equipped with bellying 5, brake block 4 is equipped with the recess 6 with bellying 5 complex. The brake pad 4 is arranged on the rotating shaft 2, the brake pad 4 is arranged in the housing 3, and the housing 3 can prevent the brake pad 4 from rotating; when the motor is electrified, the rotating shaft 2 overcomes the frictional resistance to rotate; when the motor is powered off, the motor is braked due to the frictional resistance between the rotating shaft 2 and the brake pad 4, so that the structure is simple, and the production cost is low.

In the embodiment, as shown in fig. 3, the protrusions 5 are uniformly distributed on the inner wall of the bottom of the housing 3 in the circumferential direction. When the rotating shaft 2 rotates, the brake pad 4 is stressed in the circumferential direction, and the brake pad 4 is not easy to deviate in the housing 3.
