Automobile single-arm type four-connecting-rod glass lifter

Abstract

The invention belongs to the technical field of glass lifters, and particularly relates to an automobile single-arm type four-connecting-rod glass lifter. The automobile single-arm type four-connecting-rod glass lifter comprises a motor, a speed reducer, a fan-shaped toothed plate, a gear, a base plate, a driving arm and a sliding support for mounting glass. According to the lifter, sliding of anauxiliary arm relative to a main guide rail and an auxiliary guide rail in a traditional glass lifter is avoided, namely, contact friction is avoided, noise is reduced, and meanwhile the situation that due to the fact that particle foreign matter enters a rail, running of the rail is affected, and movement between parts is hindered is avoided. According to the lifter, through the sliding support,a plurality of hinge points are formed by a first side arm, a second side arm and a driven arm, due to limitation of machining precision and consideration of cost, each hinge point can actually generate weak shaking, vibration generated after the glass is vibrated can be weakened through shaking, vibration transmitted to the driving arm is relatively small, and the driving arm is not prone to deformation.

Description

technical field [0001] The invention belongs to the technical field of window regulators, in particular to a single-arm four-link window regulator for automobiles. Background technique [0002] On a car, in order to isolate it from the outside world, it is generally necessary to install front and rear glass and door glass. In order to facilitate interaction with the outside world, the door glass has the function of lifting and lowering. The glass lifter is a device that can lift the door glass. The existing In order to reduce costs, automobiles generally use cross-arm glass lifters, while some cars can only use cross-arm glass lifters due to the overall shape, interior space layout of the door, and glass width curvature requirements. [0003] The cross-arm glass regulator has the advantages of large supporting width, relatively stable movement, fast lifting speed and low cost. However, in the process of using the existing cross-arm window lifter, there are still some proble...

AI Technical Summary

Problems solved by technology

[0004] 1. During the use of the existing automotive glass lifter, when the glass rises, the active arm pushes the upper guide groove to rise, and the glass moves upward against the front guide rail, causing the glass to flip slightly counterclockwise. On the contrary, when the glass falls If the clockwise flip occurs, if the gap between the glass and the guide groove is unreasonably controlled, the glass will be stuck, resulting in a sharp increase in system resistance

[0005] 2. During the use of the existing automotive window regulator, particles and foreign matter enter the track, which affects the operation of the track, hinders the movement between parts, affects the transmission effect of the main arm, auxiliary arm and auxiliary guide rail, and reduces Smoothness of use and longevity
