Problems solved by technology

However, the existing automatic windows that fall into the water are all pure circuit designs. In order to ensure normal operation, a large-scale waterproof treatment is required, which is costly and has a high risk of short circuit.

Embodiment Construction

[0009] exist figure 1 , the cylinder (2) device is integrally installed in the door. The pinion is the working gear of the electric window lifter, and there are no teeth at the tooth root on the rack type piston (1). When the device is not working, the rack piston (1) is at the start end of the cylinder stroke and does not contact the pinion, which does not affect the normal operation of the glass regulator, and does not contact the pinion at the end of the stroke. In some cases, after the glass is lowered, the lifter can continue to be used without being affected. The inflator (3) is in the cylinder (2), and in the inflator (3) is an appropriate amount of explosives, a power supply and an igniter, which can release a large amount of gas as power to push the glass regulator down during work. The air release port (4) of the cylinder is used to release the gas in the cylinder and the air release port (4) of the cylinder has a small radius and does not enter water in the water....

Abstract

The invention relates to an active safety device for achieving self rescue by rapidly opening windows when a car falls into water, in particular to a safety self-rescue escape device by rapidly opening the windows and used for self rescue of passengers when the car falls into water. The active safety device comprises an air cylinder, a rack type piston, an air inflation device, a sensor and an emergency button. When the car falls into water, an owner actively presses down the emergency button or the sensor detects that the car falls into water, the air inflation device releases air, and the rack type piston is pushed to move and drives a pinion, so that a window glass lifter rapidly descends and self rescue is achieved. The active safety device is suitable for various types of electric and manual lifters.

Description

technical field [0001] The invention relates to a vehicle window safety device, in particular to an active safety device for quickly opening a vehicle window for safe self-rescue escape. Background technique [0002] At present, although the chances of the car falling into the water are small. Once the car accidentally falls into the water, the vehicle's electrical system will fail when it encounters water, the electric window lift function will fail, and the door will be locked by the electric lock and cannot be opened. The clean and narrow interior space of the vehicle is quickly filled with water, and the survival time of the occupants of the vehicle is very short. This is also the main reason why the survival rate of the vehicle after falling into the water is almost zero. In recent years, there have been an endless stream of fatal accidents involving cars falling into water, although steel pipes for seat headrests in emergency conditions can be used to smash glass.
