Embodiment Construction

[0016] Combine below Figure 1 to Figure 4 The shown door motor makes a specific description of its brake structure. The door motor includes a motor body 2, the front cover of the motor body 2 is connected with a reduction box 3, and a synchronous pulley 30 is installed on the output shaft of the reduction box. The back cover of the body is connected with a brake 1, and the brake includes a cylindrical connection shell 10 fixed on the back cover of the motor body. The motor shaft 20 of the motor body 2 extends into the connection shell and is equipped with a brake disc 12. The motor The rear cover of the main body is fixed with a brake seat 11 corresponding to the brake disc, and an electromagnetic coil is arranged inside the brake seat, and the electromagnetic coil generates an electromagnetic field through electrification to adsorb the brake disc on the brake seat. A bar-shaped key 14 is provided between the brake disc and the motor shaft, and a snap spring 13 is provided on...

Abstract

The invention discloses a brake structure of a motor for a door use, which comprises a motor body, wherein a brake is connected with a rear cover of the motor body; the brake comprises a barrel-shaped connection casing fixed with the rear cover of the motor body; a motor shaft of the motor body stretches into the connection casing; a brake disc is mounted on the motor shaft; a brake seat corresponding to the brake disc is fixed with the rear cover of the motor body; an electromagnetic coil is arranged inside the brake seat; the brake disc is sucked on the brake seat by the electromagnetic field produced by the power on of the electromagnetic coil. The structure can prevent the door from being pushed open forcibly and improves the safety.

Description

technical field [0001] The invention relates to a door motor brake structure. Background technique [0002] Existing door motor generally comprises following parts: motor, reduction box, synchronous pulley, encoder. This kind of door motor has a simple structure, but due to the limited self-locking ability of the geared motor, it will be forced to open by external force, which makes the door control system a potential safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a door motor brake structure to prevent the door from being forcibly pushed open by external force and improve safety. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: a door motor brake structure, including a motor body, the rear cover of the motor body is connected with a brake, and the brake includes a cylindrical brake fixed on the motor body rear cove...
