Steel-rope glass lifter for vehicle door

Abstract

The invention discloses a steel-rope glass lifter for a vehicle door. The steel-rope glass lifter comprises a lifting sliding block (2) connected with vehicle door glass. The lifting sliding block (2) is connected with a transmission steel rope (5) and arranged on a lifting guide rail (1). The transmission steel rope (5) bypasses pulleys (3, 4) to be connected with a rope-winding drum (8). A motor (6) and the rope-winding drum (8) are fixed onto a motor support (7). The lifting guide rail (1) is arranged on the motor support (7) which is connected with a vehicle door. By adoption of the above technical scheme, the steel-rope glass lifter for the vehicle door has following beneficial effects: consumption of raw material is decreased so that cost is reduced by 28. 1% and weight is decreased by 19.4% without any interference upon usability; due to decrease in parts, incidence rate of fault modes is reduced; and by reducing abrasion of the transmission steel rope, service lifetime is prolonged and reliability of a product is improved.

Description

technical field [0001] The invention belongs to the technical field of an automobile door lifting mechanism. More specifically, the present invention relates to a cable-type window regulator for an automobile door. Background technique [0002] Below in conjunction with the accompanying drawings of this specification figure 1 A brief introduction to the existing technology: [0003] Such as figure 1 As shown, the structure of the traditional car door steel rope glass regulator includes a lifting guide rail 1, a lifting guide rail bracket 10, a lifting slider 2, a pulley 3, a lifting slider 4, a transmission steel rope 5, a steel belt 11, a steel belt 14, Motor 6, motor support 7, rope reel 8, dustproof cover, spring 12 and steel cover 13 etc. [0004] Generally, the transmission steel rope 5 only circles less than half a circle on the pulley, which is prone to slipping, especially when the pulley and the pulley shaft are under a large force and the pulley cannot rotate, ...

AI Technical Summary

Problems solved by technology

[0004] Generally, the transmission steel rope 5 only circles less than half a circle on the pulley, which is prone to slipping, especially when the pulley and the pulley shaft are under a large force and the pulley cannot rotate, the transmission steel rope 5 will produce serious wear on the pulley, resulting in does not work properly and reliably

[0005] In addition, due to the large number of components in the structure of the glass regulator, the cost is relatively high, the production and assembly process is complicated, and the probability of assembly errors is relatively high; and due to the large number of components, there are many related factors such as assembly errors and component failures. It is not conducive to ensuring the quality of the lifter

Therefore, after the product is assembled on the vehicle, it is prone to failure, resulting in the user's claim

[0006] Due to the rise in the price of raw materials, but the price of the whole vehicle has been falling, the main engine company has to reduce the price of auto parts, which has brought cost pressure to auto parts manufacturers.
