Abstract

The invention relates to an automobile powerful pneumatic door opening device, which is a device capable of allowing people to escape by opening a door powerfully in time when a car door is deformed or blocked and is difficult to open since automobile accidents occur accidentally. The device comprises a push rod type air cylinder arranged at a backrest or a cushion of a seat, and a system is formed by the device, an air pump, a high pressure air storage bottle, a throttle valve, a direction control valve and a sound and light alarm device together; when a powerful force is needed to open the car door, a sound and light alarm signal is firstly sent out to promote people around the car door to leave away so that the people are prevented from being collided, and then the door is opened powerfully by the air cylinder; the end of an ejector rod of the air cylinder is provided with an explosion-proof sleeve; and an explosion-proof liquid shower pipe is arranged along an opening line of the car door, so that possibly existing flammable and explosive gas can be prevented from detonating caused by sparks produced by scraping when the car door is opened.

Description

The powerful pneumatic door opener of automobile

Technical field

This case is about automobile burst accident, makes the car door distortion and when being difficult for opening car door, the invention that the driver and conductor in buying car in installments in time opens the car door escape device.

Background technology

In recent years, because the automobile on road surface is more and more, the sudden disaster that runs into to automobile also is more and more, and need in time the open the door situation of escape of driver and conductor is also just more and more, Beijing 721 has the driver and conductor just to be suffocated in car because of the escape of can't in time opening the door when raining heavyly; The vehicle of Sichuan rescue earthquake also has because of hit by falling rocks, rescues the stranded wounded and its dead event generation that arrives owing to can not in time open the car door of distortion; Also have many cars to shunt into one another on the expressway repeatly, because wherein the fatal risk gas of delivery overflows, the event that is hurt to the driver and conductor that can not in time flee from takes place.Although the broken window escape apparatus of numerous kinds is arranged in the society, but when escaping for water, because the top of automobile does not have the place that can Gong grasp, though people can break window by sheer good luck and escape from also to be still and be unable to escape drowning end, " so " column of Chinese Central Television (CCTV) science and technology channel please specialty the man when this process of deduction, it successfully breaks to be still from water behind the window and comes outbreak out; Be used for shunting into one another at the expressway many cars of burst, if the gas leak that loads inflammable and explosive or deep-etching is arranged, driver and conductor in the zone is if can not in time open escape because car door is out of shape, its consequence is very serious beyond doubt, and Shang Weijian has this type of report that can in time open the distortion motor vehicle door arrangement, so this type of device still is badly in need of in society now.

Summary of the invention

The summary of the invention of this case is through support the push type cylinder to be installed at the backrest of seat or cushion place, be power with gases at high pressure, relying on cylinder to implement brute force opens the door, it is characterized in that, push type cylinder, appendix, choke valve, directional control valve and high-pressure pump link to each other with gascollecting cap cylinder, and the reinforcement version of band pit is installed at the car door place that contacts with the cylinder top rod.

For avoiding knock-pin to ignite fuel gas with car door friction generation spark when opening car door, the explosion-proof sheath by copper, aluminium or resin manufacture has been installed in the end of cylinder top rod.

The rescue personnel outer for ease of car opens this case from the outside under urgent situation, its directional control valve is contained in instrument board near the position of vehicle window.

For avoiding the false touch control valve, make vehicle open the misoperation of car door under steam, protective cover has been installed at the directional control valve place, and its opening end has been installed the draw ring of being convenient to operate.

For avoiding opening outdoors other people of car door mistiming bumper car, acoustic-optic alarm has been installed in this case, and its switch is installed in the opening end inboard of protective cover, and when protective cover was not opened, insulation barrier herein made switch be normally open.

For avoiding car door to rub the spark in powerful open-type and car body, have miniature positive displacement pump one have the liquid level warning function explosion-proof liquid hold-up tank in, link to each other with the shower that is installed in the car door periphery through woven hose, this shower has a plurality of mouth sprays to spray explosion-proof liquid to the car door periphery, when the enforcement brute force is opened the door, because positive displacement pump links to each other with the circuit of acoustic-optic alarm, thus can be prior to the startup of opening the door, and avoid producing spark.

The specific embodiment

As shown in Figure 1, do system's design, manual direction valve (1), air gauge (2) should design on instrument board near the car door place, high-pressure pump (3), high-pressure gas cylinder (4) is [if be used for car, this high-pressure gas cylinder can place boot], the loudspeaker (5) of band alarm voice function should place the car outside, and (vehicle is if be equipped with such air pump and gas cylinder, can directly connect, need not to install again in addition), cylinder (6) should be installed in seat backrest or cushion place, anti-explosion set (8) is installed in the end of cylinder (6) push rod (7), original two sudden strain of a muscle of the available vehicle of warning lamp (9) replaces, and does to be connected accordingly everywhere with lead (10) and appendix (11).With the speed of service that choke valve (12) is regulated the push rod (7) of cylinder (6), the position of corresponding anti-explosion set (7), at the automobile door reinforcement version (14) is installed, with screw (15) work mechanical connection everywhere.Be equipped with one have the liquid level warning function explosion-proof liquid hold-up tank (25) place correct position and fixing, pour into explosion-proof liquid (28), built-in positive displacement pump (24), be electrically connected with acoustic-optic alarm, and link to each other with shower (27) through woven hose (26), a plurality of mouth sprays are arranged at the bottom of shower (27), and it should be installed in the outer top of car door, when brute force is opened car door, can form water curtain one along release line in advance.

As shown in Figure 1, prepare manual direction valve (1), air gauge (2), high-pressure pump (3), high-pressure gas cylinder (4), the loudspeaker (5) of band alarm voice function, cylinder (6), lead (10), appendix (11), choke valve (12), and switch (18), make the protective cover (16) of band draw ring (17), there is insulation barrier (23) this end the inside, make switch (18) be normally open, (warning lamp can replace with original pair of flashing light of automobile, battery gets final product with the original battery of automobile), hold-up tank (25), explosion-proof liquid (28), positive displacement pump (24), woven hose (27) and shower (27) are done, liquid, gas connects back and fixing.

As shown in Figure 3 and Figure 4, with aluminum casting anti-explosion set (8) and reinforcement version (14), through screw (15) and support (19) with cylinder (6) is installed in back bracket (20) to support (17) or cushion bracket (21) is located, use screw (15) just to strengthen the corresponding position that version (14) is installed in car door (22) again.

Be connected with gas circuit by the circuit of doing shown in Figure 1 at last, regulate choke valve (11) and make the knock-pin of cylinder have proper speed to get final product.

During use, open protective cover (16) through draw ring (17) earlier, can connect the acoustic-optic alarm circuit simultaneously, the outer personnel of notice car avoid car door, operate manual direction valve (1) again and open car door, escape in the shortest time.

The principle of the invention is plain, and is simple in structure, easily controls, and cost is low, easily implements.At crucial moment, can save driver and conductor's life effectively from damage.
