Automobile electric glass emergency opening system and using method

Abstract

The invention discloses an automobile electric glass emergency opening system and a using method. The automobile electric glass emergency opening system comprises automobile window glass, a jacking mechanism arranged below the automobile window glass and a power mechanism providing power for the jacking mechanism, the power mechanism comprises a gear motor of original electric glass, the power mechanism further comprises a motor output shaft, a motor gear, a power output assembly, a transmission assembly, an energy storage gear and a V-shaped limiting rod; the method comprises the following steps of (1) setting an initial state; (2) storing energy; and (3) emergency opening. According to the automobile electric glass emergency opening system and the using method, under the normal condition of an automobile, an electric button is still used for controlling electric lifting of the glass window, the energy storage gear is used for tightening a flat spiral spring through an energy storage mechanism for energy storage, under the emergency condition that the whole automobile loses power, a shifting fork rod can be shifted to separate and unlock a joint gear I and the motor gear, meanwhile, a joint gear II and a transmission gear I are jointed and linked, the energy storage gear is unlocked, so that the energy of the energy storage gear is transmitted to a power output wheel to quickly open the window glass.

Description

technical field [0001] The invention belongs to the field of electric doors and windows of automobiles, and in particular relates to an emergency opening system and a use method of electric automobile windows. Background technique [0002] The glass automatic lifting system of modern cars is mainly driven by a motor. Through the transmission mechanism, the glass of the car is driven to move up or down along the glass guide rail, and can stay at any position as required. The key to the glass lifter is the motor (reversible permanent magnet DC motor) and reducer. Among them, the direction of the current is controlled by the double switch, and the rotation direction of the motor is changed to realize the three states of raising, lowering and closing the glass. However, the disadvantage of this technology is that in case of water, the circuit will be short-circuited, the control power supply will fail, and the function of glass automatic lifting will also fail thereupon. As a ...

Problems solved by technology

However, the disadvantage of this technology is that once it encounters water, the circuit will be short-circuited, the control power supply will fail, and the function of glass automatic lifting will also fail.

In the event of an emergency such as flooding, the clutch worm driven by the energy storage spring can only be linked with the shaft of the lifting DC motor after displacement, and there is a lag. At this time, the DC lifting motor has lost power, and the shaft of the DC lifting motor is self-locking, and the glass cannot Lifting, the energy of the energy storage spring needs to overcome the self-locking resistance of the DC lifting motor to drive the reduction gear, so that the window glass is lowered, it is difficult to open, and the transmission efficiency is low
