Manual and electric two-way converter of vehicle window operator

Abstract

A both manual and electric changeover unit for the glass lift of car features that the locating sleeve, bearing and clutch sleeve are sequentially sleeved on the changeover axle of rockerarm. Said clutch sleeve has several notches. A locating pin is arranged in said changeover axle between bearing and clutch sleeve. A drive sleeve sleeving on said changeover axle has an axle installing hole at its front end and several steel ball holes for holding steel balls in them. Its advantages are simple structure and flexible operation.

Description

1. Technical field [0001] The invention relates to a glass lifter for automobile windows, in particular to a manual and electric dual-purpose conversion device for the automobile glass lifter. 2. Background technology [0002] Existing automobile window regulators have two control methods, manual and electric. The manual control method is inconvenient to use; the disadvantage of the electric control method is that when the motor fails, the worm gear will be locked, resulting in the glass cannot be lifted and lowered, which is prone to danger, has potential safety hazards, and is inconvenient to maintain. Chinese Invention Patent Specification CN 1085596C (authorized announcement date: May 29, 2002, patent number: 97125308.0) discloses a hand-operated and electric dual-purpose motor vehicle window lifter, including a driving arm, a slave arm, a cross Brackets, arc-shaped ring gears, driving gears, crank handles, hollow shaft tubes, worms, worm gears and other components, amo...

AI Technical Summary

Problems solved by technology

The manual control method has the disadvantage of being inconvenient to use; the disadvantage of the electric control method is that when the motor fails, the worm gear will be locked, resulting in the failure of the glass to rise and fall, which is prone to danger, has potential safety hazards, and is inconvenient to maintain

With this kind of key-tooth fit or key-tooth connection, when the electric switch is converted to manual, the pulling force required to pull the rocker backward is relatively large, especially when the glass is raised to the top of the window and then converted to manual backward. Greater pulling force; difficult to find engagement or disengagement position when crank is pushed forward or pulled back when switching from electric to manual

These are inconvenient to use, and the above-mentioned curved ring gear, driving gear, hollow shaft tube and other parts have complex structures and troublesome processing
