Description
Technical field
The present invention relates to a kind of window breaker, particularly a kind of multi-functional Portable Automatic window breaker belongs to emergency management and rescue equipment field.
Background technology
Fast development along with national economy, vehicle has become the indispensable instrument of functioning in an acting capacity of of modern, the accident that vehicle occurs takes place again and again, as Chengdu public transport spontaneous combustion in 2009, cause the 25 people accident of dying in an accident, Beijing extra torrential rain caused a car owner can't escape in the car that is not had by water logging and died in an accident double-deck big bus fire accident on the Jingzhu express way highway on July 21st, 2012, cause 41 people wrecked etc., trip safety more and more becomes the problem that family and self-driving family by bus are concerned about most.Because the continuous construction of high-grade highway and improving constantly of living standards of the people, environment inside car under the closed state more can keep comfort level and safety, but another problem is, in case occur accident in the car, the escape fast of how meeting an urgent need is just particularly important, measure is untimely, lacks the necessary measure of saving oneself, and will threaten rider's life and property.
Therefore escape way is the life passage that people evacuate, escape, with glass wall or the comparatively broad temporary access road of glass port broken formation of moment, be convenient to personnel in time, quick, escape unharmed is on-the-spot, can reduce personal casualty in a large number, be one of effective measures of avoiding the severely injured Extra Serious Accident generation of the dead group of group.
At present, broken glass port device is varied on the market, and widely used broken glass port device is in the majority with safety hammer, sometimes also with flatehead ax as broken glass device.Safety hammer breaks glass economy, arranges easily, and is easy-to-use, but when running into some thicker case hardened glasss, such as the case hardened glass of 5-12mm, the broken glass reliability of common safety hammer also descends thereupon, not broken situation often occurs pounding.The use of safety hammer needs certain skill, at the situation of improper use reliable shattered glass in following blink.Flatehead ax also is a kind of common broken glass device, but owing to its its portability of heavy appearance effects and operability, is not easy to extensively equip and use.Also have some integrated broken glass devices, CN201020629994.0 glass smasher as the broken glass of armrest palm extruding, by the CN2012795185A window breaker of the stubborn broken glass port of screw, be fixed in the vehicle and break the glass acting device by what the circuit centralized control was operated as the broken window device of the CN201120292641.0 closed in spaces vehicle and CN201120076985.8.These window breakers, need with the broken glass port of bigger external force, broken glass port long action time, complex operation, circuit control is concentrated in wiring on the fixing glass window, these broken window devices are installed the restriction with occupation mode, especially in the narrow relatively C-class in space, be window breaker to be installed or all there is big difficulty in urgent broken glass window in car, also being difficult in the purpose that reaches fast broken glass in the emergent broken glass escape and rescue process.
Usually the emergency management and rescue escape equipment that arranges in the car also has high light flash light, siren horn, parking warning board etc., these things all are not placed on the desirable position of can whipping at ordinary times, in case accident occurs, often can not in time find out and use and miss the good opportunity of saving oneself.
Summary of the invention
