Fork arm type electric glass lifter

Abstract

The invention provides a fork arm type electric glass lifter which comprises a movable guide rail, a fixed guide rail, a driving arm, a driven arm, a panel and a driving gear, wherein the driving arm and the driven arm are hinged in an X shape through a hinging piece; the driving arm is hinged with the panel and comprises a first long arm, a second long arm and a first spring; two ends of the first spring are respectively connected with the first long arm and the second long arm; the driven arm comprises a first short arm, a second short arm and a second spring; and two ends of the second spring are respectively connected with the first short arm and the second short arm. According to the fork arm type electric glass lifter disclosed by the invention, the movable arms and the springs are additionally arranged, so that the extension of the driving arm and the driven arm is realized. In the process that an automobile window is opened or closed, the driving arm and the driven arm of the fork arm type electric glass lifter disclosed by the invention are automatically adjusted in length simultaneously along with the vertical motion and the centre-of-gravity shift of automobile window glass, and thus no inclination of the automobile window glass is ensured and the driving safety is improved.

Description

technical field [0001] The invention belongs to the field of auto parts, and in particular relates to a fork arm type electric glass lifter. Background technique [0002] The wishbone type electric window lifter is a window glass lifting appliance commonly used in automobiles. The wishbone type electric window lifter is equipped with a DC motor gear to drive the long arm gear fan to rotate, and then through the conversion of the fixed guide rail and the short arm, To drive the moving guide rail to move up and down vertically, the window glass is installed on the moving guide rail, and the motor power switch is turned on, and the car window glass just rises or falls with the rotation of the motor. The quality of the car lifter directly affects the safety of passengers. Due to the quality problem of the lifter, the window glass cannot be raised and lowered, causing passengers to suffer from freezing in severe winters, being drenched in heavy rain, and carbon monoxide poisoning...

AI Technical Summary

Problems solved by technology

The quality of the car lifter directly affects the safety of passengers. Due to the quality of the lifter, the window glass cannot be lifted up and down, causing passengers to suffer from freezing in severe winters, rainstorms, and carbon monoxide poisoning.

However, at present, the structure of the fork-arm type electric window lifter at home and abroad is similar. The long and short arms of the lifter cannot automatically adjust the glass balance due to the offset of the center of gravity of the window glass, and it is easy to cause the glass to stick to the guide rail, glass breakage, and the lifter. Faults such as twisting, deformation, and damage to the door guide rail

At the same time, the long arm tooth fan transmission part and the glass lifting transmission part of the existing lifter are made of the same material with the same hardness and are easy to wear and tear. Due to the wear, the long arm tooth fan transmission part and the glass lifting transmission part become loose, causing the electric glass The lifter failed, posing a serious threat to the personal safety of passengers
