Description

Automobile electric glass emergency opening system and using method

Technical Field

The invention belongs to the field of automobile electric doors and windows, and particularly relates to an automobile electric glass emergency opening system and a using method thereof.

Background

The glass automatic lifting system of modern automobile is mainly characterized by that it is driven by motor, and utilizes transmission mechanism to drive automobile glass to make lifting or lowering movement along the glass guide rail, and can be stopped at any position according to the requirements. The key of the glass lifter is a motor (reversible permanent magnet direct current motor) and a speed reducer. The direction of the current is controlled through the duplex switch, the rotating direction of the motor is changed, and the three states of lifting, descending and closing of the glass are achieved. However, the disadvantages of this technique are: once meeting water, the circuit is short-circuited, the control power supply fails, and the automatic lifting function of the glass also fails. So that the driver can not drop the glass to escape in time after losing the electric power, thereby possibly causing casualty accidents.

In daily life, once the rain storm weather occurs, the vehicle flooding condition or even the emergency condition of water flooding is easy to happen on a tunnel or a low-lying road section. If the driver does not drop the glass in time or the glass is in a closed state at this time, people in the vehicle cannot escape from the vehicle at the first time, the escape difficulty is increased, and casualty accidents are caused. The existing patent has designed multiple urgent opening device, it is urgent to electric glass to open after having utilized the coil spring energy storage mostly, like the emergent windowing facility of car electric window of patent number 201310492054.X, the emergent descending device of electric vehicle window glass of application number 201410048009.X, the emergent windowing facility of car electric window of application number 201310017934.1, the emergent windowing facility of car electric window of application number 201310438689.1, but coil spring vertically has taken up great space, it is great to car design influence. In order to solve the problem, other patents propose to store energy by using a flat spiral spring, such as an emergency descending device of an automobile electric vehicle window glass of application number 201310643138.9, which adds a set of energy storage direct current motor (4) to store energy for the flat spiral spring (7) through a composite reduction gear (5). When an emergency button (11) in the automobile acts, the middle sliding shaft (10) unlocks the lifting direct current motor and the winding wheel (3), and simultaneously, under the action of the retaining pin (9), the winding wheel is interlocked with the flat spiral spring and the rotating wheel (8) to drive the window glass to rapidly descend. The invention has the advantages that 1, the energy storage direct current motor stores energy for the spring, the window glass of the main tube of the lifting direct current motor is lifted, and the energy of each row is not influenced. 2. In an emergency state, the energy stored by the flat spiral spring is used as the power for the descending of the window glass, and the window glass does not depend on a power supply, so that the window glass is safe and reliable. However, the device needs to be additionally provided with a set of energy storage direct current motor, and the cost is higher. Like the emergent descender of automobile electric motor car window glass of application number 201310552503.5, it has increased a set of separation and reunion worm, spring tensioning gear, energy storage spring, ratchet pawl and trigger mechanism, bow spring piece device and the interior emergency button of car on the basis of original electric motor car window direct current elevator motor and reduction gear. When the electric vehicle window descends, the lifting direct current motor shaft drives the clutch worm to rotate, and energy is stored for the energy storage spring. When the energy storage spring is fully loaded, the clutch worm moves right to be separated from the shaft of the direct current lifting motor, and the rising and falling of the window glass of the electric vehicle are not influenced. When the automobile is in an emergency, such as water flooding, the electric appliance fails and cannot open the window glass of the electric automobile, the trigger mechanism separates the ratchet wheel and the pawl only by pressing the emergency button in the automobile, the spring full of energy starts to work, the clutch worm is driven leftwards and then linked with the lifting direct current motor shaft to reversely drive the reduction gear, so that the window glass descends. When emergency such as flooding occurs, the clutch worm driven by the energy storage spring can be linked with the shaft of the lifting direct current motor after displacement, hysteresis exists, at the moment, the direct current lifting motor loses power, the shaft of the direct current lifting motor is self-locked, the glass cannot lift, the energy of the energy storage spring can drive the reduction gear only after overcoming the self-locking resistance of the direct current lifting motor, so that the window glass descends, the opening difficulty is high, and the transmission efficiency is low.
