Centrifugal protection electromagnetic adsorption type electrorheological glass lifter motor

Abstract

A centrifugal protection electromagnetic adsorption type electrorheological glass lifter motor relates to the technical field of motors and comprises an output shaft, and an inner top wall of the output shaft is provided with a sliding rail. The centrifugal protection electromagnetic adsorption type electrorheological glass lifter motor and an electro-magnetic device are used in a cooperative manner through electrically conductive block one. In an initial state, a rubber ring is attached to a clamping groove, a suspending liquid changes into a solid state in a power-on state, the rubber ring is enabled to be connected with a transmission toothed wheel in a clamped manner to facilitate transmission of the output shaft and the transmission toothed wheel. When the rotating output shaft suddenly stops rotating, inertia which is generated causes the electrically conductive block to slide along a slide rail in a rotation direction and to be connected with the electro-magnetic device in a clamped manner; the rubber ring becomes circular in shape, the diameter of the rubber ring is equal to the inner diameter of the transmission toothed wheel. At this time, the output shaft is used for driving the rubber ring again to idle in the transmission toothed wheel, thus the motor can be protected, the motor can be effectively prevented from overload and overheating which occur when the motor is unable to rotate, and the service life of the motor can be prolonged.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor for a centrifugal protection electromagnetic adsorption type electrorheological glass lifter. Background technique [0002] The glass lifter is a device used to control the lifting of the glass of the side door of the car. The glass is lifted and lowered by controlling the positive and negative rotation of the motor, which saves manpower and improves the comfort of the car. [0003] When the current glass lift motor is in use, when the glass rises to the top or falls to the bottom, the motor cannot rotate because the glass moves to the maximum position, resulting in overload and overheating of the motor, which will cause great damage to the motor. It is easy to cause the motor to burn out, shorten the service life of the motor, and after the motor is damaged, the glass cannot be closed normally, and the property safety in the car cannot be guaranteed. [0004] Therefore, ...

Problems solved by technology

[0003] When the current glass lift motor is in use, when the glass rises to the top or falls to the bottom, the motor cannot rotate because the glass moves to the maximum position, resulting in overload and overheating of the motor, which will cause great damage to the motor. It is easy to cause the motor to burn out and shorten the service life of the motor. Moreover, after the motor is damaged, the glass cannot be closed normally, and the property safety in the car cannot be guaranteed.
