A motor for window lift with overload protection

Abstract

A vehicle window lifting motor capable of overload protection relates to the technical field of motors. The motor includes a connector. An inner wall of the connector is provided with uniformly distributed clamping grooves, an output shaft is connected on a middle part of the connector in a clamped manner, and evenly distributed fixed columns are fixedly connected on an inner wall of the output shaft. In the vehicle window lifting motor capable of overload protection, clamping blocks and the clamping grooves are used in a cooperative manner, the clamping blocks are connected with the clampinggrooves in a clamped manner in an initial state, and the connector is enabled to be connected with the output shaft in a clamped manner; when the rotating output shaft suddenly stops, a limiting blockmoves towards a front side due to centrifugal force, an electrically conductive sheet is driven to move toward the front side, the electrically conductive sheet is separated from a rheostat, a circuit for suspending liquid is disconnected, the suspending liquid is turned into fluid, the clamping blocks are squeezed into the output shaft under the action of the clamping grooves, piston blocks moveto both sides under the action of the suspending liquid to make the output shaft idle, thus overload protection can be achieved, overload use of the motor can be prevented, and service life of the motor is prolonged.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor for lifting and lowering vehicle windows that can be protected against overload. Background technique [0002] The glass lift motor is mainly used to control the lift of the side door glass of the car. The lift motor and the glass lifter are used together to realize the electric control of the lift of the glass and improve the user experience of driving. [0003] Most of the current glass lifting motors realize the lifting of the glass through forward and reverse rotation. However, when the glass rises to the top or falls to the low end, the motor cannot stop working in time, which will cause the motor to overload and cause the temperature inside the motor to rise. , It is easy to burn out the motor and reduce the service life of the glass lift motor. [0004] Therefore, we have proposed a motor for window lifting with overload protection to solve the above problems. The ...
