Anti-terror car-attack defending apparatus

Abstract

A car-attack defending apparatus includes a pressure-sensitive reaction module, an emergent airbag-inflation module, a crash barrier module, and an integral exterior unit module, wherein the pressure-sensitive reaction module has a pressure-sensitive setting and triggering mechanism, the emergent inflation airbag module has an emergent airbag expansion mechanism, and the crash barrier module has a crash-resistant steel plate. The car-attack defending apparatus can be disposed at entrances of specific buildings or restricted areas, so that at the moment a suspected car ignores warning and attempts to access the site, the emergent airbag expansion mechanism will be triggered, by the weight of the car, so as to expand the airbag simultaneously, and to stretch the crash-resistant steel plate to form a barrier. As such, the suspected car can be prevented from moving further, allowing checkpoint personnel a safe standoff distance from car bombs.

1 . An anti-terror car-attack defending apparatus, comprising:
 a pressure-sensitive reaction module, including a pressure-sensitive setting and triggering mechanism, a pressure-sensitive triggering panel, and a signal-transmission cord;   an emergent airbag-inflation module, including an airbag body, an emergent explosion and air-producing mechanism, and an electronic detonator triggering mechanism;   a crash barrier module, including a crash-resistant steel plate and a linkage assembly; and   an integral exterior unit module, including a reinforced housing, a drainage device, and an exterior warning loop;   wherein the pressure-sensitive triggering panel is triggered by a suspected car moving on a surface in a movement direction, with a triggering signal transmitted to the pressure-sensitive setting and triggering mechanism which actuates the emergent explosion and air-producing mechanism to inflate rapidly the airbag body, such that the linkage assembly stretches and holds the crash-resistant steel plate at a certain angle to form a barrier so as to prevent the car from moving further.   
   
   
       2 . The anti-terror car-attack defending apparatus as claimed in  claim 1 , wherein prior to triggering the pressure-sensitive triggering panel by the car, the airbag body maintains at a flat status, and the linkage assembly is not stretched and the crash-resistant steel plate lies horizontally. 
   
   
       3 . The anti-terror car-attack defending apparatus as claimed in  claim 1 , wherein the pressure-sensitive triggering panel is made of metal. 
   
   
       4 . The anti-terror car-attack defending apparatus as claimed in  claim 1 , wherein the pressure-sensitive triggering panel is made of fiber glass. 
   
   
       5 . The anti-terror car-attack defending apparatus as claimed in  claim 1 , the reinforced housing is constructed with metal. 
   
   
       6 . The anti-terror car-attack defending apparatus as claimed in  claim 1 , wherein the reinforced housing is constructed with prefabricated concrete. 
   
   
       7 . The anti-terror car-attack defending apparatus as claimed in  claim 1 , wherein the apparatus is controlled by an electric power switch so as to turn on or off the apparatus for a thorough function. 
   
   
       8 . The anti-terror car-attack defending apparatus as claimed in  claim 1 , wherein the crash-resistant steel plate, after inflation of the airbag body, is held at an acute angle to the surface in which said acute angle faces in a direction opposite to the movement direction of the suspected car. 
   
   
       9 . The anti-terror car-attack defending apparatus as claimed in  claim 1 , wherein the reinforced housing of the integral exterior unit module accommodates the airbag body, the electronic detonator triggering mechanism, the crash-resistant steel plate, and the linkage assembly.
