Abstract

The invention discloses an emergency car window blasting system based on an electromagnetic vortex effect. The emergency car window blasting system comprises a power supply, a time delay switch, a high-frequency inverter, four coil groups and a car window, wherein the periphery of the car window is fixed between the inner wall and the outer wall of a car; the car window is provided with holes; platform-shaped iron cores are embedded into the holes; each platform-shaped iron core corresponds to one coil group; each coil group is constructed by connecting a coil I and a coil II in series; one end of the time-delay switch is connected with the anode of the power supply; the cathode of the power supply and the other end of the time-delay switch are connected with the two input ends of the high-frequency inverter respectively; the two ends of the four coil groups which are connected in parallel are connected with the two output ends of the high-frequency inverter respectively. According to the emergency car window blasting system, the platform-shaped iron core is heated in a short time by using the electromagnetic vortex effect in order to expand the platform-shaped iron core to realize window breaking; by adopting the time-delay switch, risk caused by continuous rising of the temperatures of the platform-shaped iron cores after breaking of the window can be avoided; moreover, the platform-shaped iron cores are hidden on the edge of the car window, so that a passenger can be protected from being scalded by overheat. The emergency car window blasting system is convenient to use, and window breaking can be performed rapidly.

Description

Emergent vehicle window blasting system based on electromagnetic eddy effect

Technical field

The present invention relates to a kind of blasting system, more particularly, to a kind of emergent vehicle window blasting system.

Background technology

With the increasingly lifting of living standard, the popularity rate of automobile increases year by year.Automobile is as must in people's daily life The indispensable vehicles, the security performance of vehicle seems all the more important, and vehicle buyer gets over to the attention degree of security performance Come higher, the security performance of vehicle has directly influenced the sales volume of vehicle, and the active safety performance of therefore vehicle is also more next More paid attention to by each big automaker and consumer.

Production technology level with the development glass of modern science and technology level is constantly lifted, and large commercial vehicle is adopted at this stage Glass for vehicle window intensity is all very high.When vehicle has an accident especially fire incident, passenger inside the vehicle is difficult to only according to manpower Vehicle window is broken to escape, this can cause many unnecessary injures and deaths.Therefore, be badly in need of be equipped with large commercial vehicle supporting Automatic escape device, to ensure that passenger can have passway for escaping when causing danger.

Content of the invention

It is an object of the invention to provide a kind of window easy to use, broken efficiently the emergent vehicle window based on electromagnetic eddy effect is quick-fried Broken system.

The emergent vehicle window blasting system based on electromagnetic eddy effect of the present invention, including power supply, delay switch, high-frequency inversion Vehicle window between device, four coil groups and the inside and outside wall being fixed on compartment, each coil group is connected structure by coil one and coil two Become, vehicle window edge is evenly equipped with four holes, each in the hole is inlaid with a round table-like iron core, each round table-like iron core and a coil Group corresponds to, and coil one is positioned at the two ends of round table-like iron core and coaxial with round table-like iron core respectively with coil two, and coil one is fixed on The inwall of railway carriage, coil two is fixed on the outer wall of railway carriage, and, facing to outside car, big bottom surface direction is in-car for the handle of round table-like iron core, Positive source is connected with one end of delay switch, and the other end of delay switch is connected with high-frequency inverter input, electricity Source negative pole is connected with another input of high-frequency inverter, the two ends after the parallel connection of four coil groups respectively with high-frequency inverter Two outfans connect.

When being in an emergency, close delay switch, high-frequency alternating magnetic is produced due to larger current in short-term in coil , in two coils of a coil group, magnetic field mutually strengthens so that producing strong eddy current effect, round platform in round table-like iron core Temperature raises shape iron core quickly under the influence of a magnetic field, rapid spatial expansion, and glass for vehicle window is in round table-like iron core expanded by heating Automatically rupture under stress, thus opening passway for escaping.

The delay switch time is preferably set at 15 seconds about, leads to round table-like iron core temperature mistake to prevent from being energized for a long time Height, round table-like iron core can be using the higher ferrimagnet of fusing point, to ensure the heats of eddy current effect.Using round table-like Iron core be easily installed and dismantle, and when installing will big bottom surface towards in-car, the side of its internal power when can adjust glass explosion To so as to extra-owing digging is towards outside car, prevent glass fragment from hurting sb.'s feelings.More severe in order to prevent splashing glass during rupture from causing Impact, preferably posts rupture pressure disc inside and outside vehicle window.

The beneficial effects of the present invention is: the present invention adopts electromagnetic eddy effect in the round table-like iron core of interior heating in short-term, makes It expands thus realizing broken window, round table-like iron core temperature after window can be avoided brokenly to continue to raise the danger bringing using delay switch, And round table-like iron core is hidden in vehicle window edge, can prevent from overheated leading to passenger's scald；The emergent vehicle window blasting system of the present invention, Easy to use, broken window is quick.
