Description

Reusable window breaker based on electromagnetic principle

Technical field

The present invention relates to a kind of window breaker for capableing of quick automatic window breaking, it is specifically a kind of based on electromagnetic principle can Reuse window breaker.

Background technique

With the development of China, people use automobile more and more frequent as walking-replacing tool, therefore vehicle safety is just at me Must not thinking imprudent the problem of.There is an urgent need to a kind of window breakers rapidly and efficiently, securely and reliably, also occur one in recent years A little mechanical and blasting type window breakers, but have some shortcomings: the power certain using some need of mechanical window breaker Or certain skill is needed, (such as impact position choosing not pair or power is inadequate) cannot can in the lower short time the improper use the case where By shattered glass, it is also possible to break window because injured or space problem is unable to use device, cause effectively to escape；And blasting type is broken Window device generally uses high pressure gas or gunpowder, has security risk, may damage to occupant, furthermore cannot be secondary It utilizes, is not energy-saving and environment-friendly.

Summary of the invention

Present invention aims to broken windows to become safe and reliable, controllable, efficient, provide a kind of based on electromagnetic principle Reusable window breaker.

The technical solution for realizing the aim of the invention is as follows: a kind of reusable window breaker based on electromagnetic principle, by Shell, guide rail, armature, striker, spring, bottom plate composition, guide rail consolidate on the shell, and shell one end is equipped with aperture, and inside is fixed There is spring, one end is mutually fixed with bottom plate, and the guide rail is equipped with groove, and armature can slide in groove, and be in electrical contact good Good, by conducting wire and external power supply composition circuit, circuit switch is mounted on driver's platform, pacifies before armature for armature and guide rail Equipped with striker, the striker is pointed shape, and when dangerous situation occurs, driver presses lower switch, and guide rail and armature, which are powered, generates magnetic , at armature rear, the vertical paper of the magnetic line of force is upward, and Interaction Law of Electric Current generates Lorentz force, Lorentz in the magnetic field and armature Power provides the kinetic energy to travel forward for striker and armature, pushes striker and armature to move out and is reached brokenly by aperture shock glass Window purpose, and reset under the action of the spring.

Compared with prior art, the present invention its remarkable advantage are as follows: (1) use electromagnetic drive in the present invention, clean energy is easy , use scope is wide, and the size of impact force is controllable, securely and reliably；(2) there is spring reverse motion, reusable, section It can environmental protection；It is (2) simple and quick as long as driver can be fast implemented brokenly the purpose of window by lower switch in time when dangerous situation occurs, People is rescued in danger and disaster.

Detailed description of the invention

Fig. 1 is top cross-sectional view of the invention.

Fig. 2 is the partial cutaway view in the face Figure 1A-A.

Specific embodiment

Technical solution of the present invention is introduced with reference to the accompanying drawing, and in the following description, striker direction of advance is known as " preceding ", opposite direction are known as " rear ".

In fig. 1, it is the sectional view of main component of the invention, including shell 1, striker hole 2, bottom plate 3, spring 4, leads Rail 5, armature 6, striker 7.Wherein, shell 1 has determined that the shape of whole device is cuboid, and front end face is provided with striker hole 2, hole Diameter is slightly larger than the diameter of striker 7, and 1 rear end face of shell consolidates bottom plate 3, closes whole device.1 inner wall two sides of shell are consolidated with Guide rail 5, guide rail 5 are equipped among two 5 grooves of guide rail of groove and are equipped with armature 6, and armature 6 can slide between guide rail 5 and electricity connects Touching is good, and constitutes circuit by conducting wire and external power supply, and the on-off of circuit is controlled by vehicle-mounted urgent trigger button, 6 bottom of armature Portion abuts bottom plate 3, and front end is welded striker 7, and spring 4 is equipped between armature 6 and striker hole 2, and the length of spring 4 is equal to two The distance between person, the diameter of spring 4 are greater than the diameter in striker hole 2, but less than the distance between two guide rails 5, the non-work of device As when play the role of position-limiting action to armature 6, play reset at the end of work.

Armature 6 is slided in guide rail 5 in fig 2 and is further described, which is the section view in the direction Fig. 1 A-A Figure.As seen from the figure, guide rail 5 is closely fixedly arranged at 1 two sides of shell, and guide rail 5 is equipped with groove, and armature 6 is matched by groove with guide rail 5 It closes, 6 two side walls of armature have the gap with 5 two sides of guide rail, do not contact, and only upper and lower surface has small part to contact with guide rail 5, Guarantee that armature 6 can slide in groove and frictional force is small.

The shell 1 be nonmetallic materials such as: plastics；The spring 4 has coefficient of elasticity appropriate, plays armature Limit and the effect resetted.

Slidably distance is 4 to 6 centimetres to the armature 6 in guide rail 5.

The bottom plate 3 is insulating materials, is divided into two layers, and inside one layer is rubber layer, plays windowpane when striker 7 is hit Afterwards, it can be resetted under the action of spring 4, rubber layer has the function of buffering at this time, armature can be protected to greatest extent, in order to To reuse, another layer is made of plastics, plays support.

With reference to the accompanying drawings, whole device is fixed by the bracket on window frame of automobile first, and shell 1 is equipped with the one end pair in striker hole 2 Quasi- glass for vehicle window；When dangerous situation occurs, passenger and driver can be powered by vehicle-mounted urgent trigger button, and electrified rail 5 generates magnetic , the magnetic field is upward in 6 rear vertical paper of armature, and Interaction Law of Electric Current generates Lorentz force, Lorentz in magnetic field and armature 6 It pushes dynamic striker 7 and the acceleration of armature 6 travels forward, small part kinetic energy is stored by spring 4, and most of kinetic energy makes striker 7 contact glass Huge impact force is generated when glass, to realize rapid window-breaking.Spring 4 can not only prevent striker 7 from projecting outside window at the end of broken window Crowd outside window is damaged, moreover it is possible to reset lower armature 6 backward under the effect of elasticity, the rubber layer on bottom plate 6 can be at this time Row buffering prevents armature from damaging.
