Limiting and damping mechanism for car window glass lifter

Abstract

The invention discloses a limiting and damping mechanism for a car window glass lifter. The limiting and damping mechanism comprises a sector fluted disc, a main arm, a secondary arm, a long chute and a short chute; a limiting damping stop dog structurally matched with the long chute is glidingly arranged in the long chute; the limiting damping stop dog is arranged in the long chute between a universal roller of the main arm and a universal roller of the secondary arm; the length of the limiting damping stop dog is equal to the distance between opposite surfaces, in the long chute, of the universal roller of the main arm and the universal roller of the secondary arm when the main arm and the secondary arm move to an upper stop point or a lower stop point; a sliding track and a groove are arranged at the lower plane, matched with the bottom of the long chute, of the limiting damping stop dog; the sliding track is provided with a plurality of sliding convex points. The limiting and damping mechanism for the car window glass lifter realizes the limiting on the actuating range of the secondary arm of the lifter, and solves the vibrating phenomenon of a door plate in the glass lifting process.

Description

technical field [0001] The invention relates to the technical field of automotive glass regulators, in particular to a position-limiting and shock-absorbing mechanism of an automotive window regulator. Background technique [0002] At present, the auxiliary arm of the car wishbone type window regulator is directly installed in the long chute through the slider, and the long chute cooperates with the slider. This structure cannot reasonably control the movement of the auxiliary arm AB, and thus cannot The rising and falling height of the glass is well controlled, and the existing glass lifter easily generates impact force between the glass and the door frame when the glass rises to the top, causing vibration of the door panel. At the same time, this impact force will also greatly reduce the service life of the automotive window regulator, and will also cause discomfort to the use of the entire vehicle.

AI Technical Summary

Problems solved by technology

[0006] The above technical solution solves the problem that when the glass rises to the upper limit position, the motor continues to drive the gear to mesh with the tooth plate, causing damage to both the motor and the gear tooth plate

[0007] To sum up, in the prior art, there is no effective solution to the problem that the actuation of the auxiliary arm of the automobile fork-arm type window lifter cannot be reasonably controlled, the height of the rising and falling of the glass cannot be well controlled, and the glass lifter cannot be properly controlled when the glass rises to the top. A technical solution for problems such as glass and door frame likely to generate impact force, causing vibration of the door panel
