AI Technical Summary

Technical Problem

The existing electric seat height adjustment motors for cars have only a single contact surface between the sliding plate and the gearbox, which makes them prone to damage due to excessive force. In addition, the screws are easy to loosen, affecting the reliability and lifespan of the motor.

Method used

Multiple force-bearing surfaces are set between the sliding plate and the gearbox, and support bosses are added at the screw holes of the gearbox cover plate. By distributing the load through multiple force-bearing surfaces, the thrust of the screws is reduced, ensuring smooth motor operation and screw tightening.

Benefits of technology

This effectively prevents localized damage to the gearbox, reduces motor noise, ensures smooth motor operation, and keeps the screws locked during repeated operation, extending the motor's service life.

Abstract

The utility model discloses a height adjusting motor for an electric seat of an automobile. The height adjusting motor for the electric seat of the automobile comprises a flat motor rear cover assembly; a cavity for mounting the gear set is formed in the gear box; the sliding plate comprises two U-shaped guide parts, the two ends of the two U-shaped guide parts are fixedly connected, and the side faces, away from each other, of the two U-shaped guide parts are each fixedly connected with two connecting parts. A plurality of stress surfaces are arranged between the sliding plate and the gear box, so that the gear box can be prevented from being damaged due to overlarge stress on a single surface, the motor can run more stably and smoothly, the noise of the motor can be reduced, the added supporting boss and the head of the screw can jointly bear the received forward and reverse thrust, and the service life of the screw is prolonged. In the repeated forward and reverse rotation process of the motor, the screw can be always kept in a locking state, the reliable operation of the motor is ensured, and the service life of the motor is prolonged.
