Description
Technical field
The present invention relates to a kind of escape systems of public transport, more specifically, it relates to window breaking device, public visitor
Vehicle emergency broken window system and broken window method.
Background technology
In recent years China's public transport uses vehicle number rapid increase, once contingency occurs for vehicle, passenger needs quick
Get off, however, the channel width due to car door is limited, the lower vehicle speed of passenger is caused to slow down, in addition can because car door can not
It opens and is stranded in the car, seriously threatened the life security of passenger.Thus, window breaker can be all generally installed on bus（Again
Claim safety hammer）, passenger can be used window breaker directly vehicle window is broken up, then escaped from from vehicle window.At present on bus in order to reach
Sun-proof purpose generally can all paste one layer of sunscreen film on vehicle window, so, even if passenger can use window breaker easily will
Vehicle window is broken up, but the glass of fragmentation can still be connected, and at this moment just needs to be detached the glass being connected with hand.In this process
In, the hand of passenger is easy to by glass scratch.
Invention content
In view of the deficienciess of the prior art, first of the present invention is designed to provide a kind of window breaking device, Neng Gou
After breaking up vehicle window, the glass being linked together can directly be detached with hand contact glass without passenger.
To achieve the above object, the present invention provides following technical solutions：
A kind of window breaking device is applied on public bus, including is installed on pedestal near vehicle window, is rotationally connected on pedestal
Pneumatic automatic window breaking device is set on pedestal and is used in response to one first control instruction to drive the pneumatic automatic window breaking device

Make, the glass 32 of vehicle window 9 is broken up.Then operation and control device 1 sends the first control instruction to first driving means, makes first
Motor rotates, and then the direction for driving pneumatic automatic window breaking device 8 to be directed away from vehicle window 9 rotates；After rotateing in place, then operate control
Device 1 processed sends the second control instruction to the second driving device, so that the second motor 25 is rotated, will entirely keep off glass plate 13 and rise, directly
It is higher than the bottom wall of vehicle window 9 with the tie point of bottom plate 14 to the first plate body 16；Finally, passenger can be directly by the second plate body 17 towards vehicle
The outside of window 9 pushes, to be squeezed unsegregated glass 32 using the second plate body 17；When the second plate body 17 turns to vertical state
When, support plate 19 is horizontal, and support plate 19 constitutes the structure of similar cat ladder with the second plate body 17 at this time, and then passenger can
It steps down in support plate 19 and is safely climbed down from vehicle window 9.
Embodiment 2：
The present embodiment is substantially the same manner as Example 1, difference lies in：
One, with reference to Fig. 7 A, the position detection component of the position for detecting deflection arm 7, position detection component are provided on pedestal 6
It is electrically connected with controller 1.In the present embodiment, which uses close switch 26, is correspondingly provided on deflection arm 7
The metallic object 27 that switch 26 detects can be approached；When 7 state in a vertical shape of deflection arm, the metallic object 27 is close and triggers close
Switch 26；The switching signal of high level is sent close to switch 26 to controller 1.In turn, when deflection arm 7 is rotated to horizontality
When, metallic object 27 sends low level switching signal close to switch 26 far from close to switch 26 to controller 1.
With reference to Fig. 7 B, the air inlet of pneumatic automatic window breaking device 8 is connected with electromagnetic switching valve 28, electromagnetic switching valve 28 and control
Device 1 is electrically connected.When controller 1, which controls electromagnetic switching valve 28, to be acted, the air pressure of pneumatic automatic window breaking device 8 disappears, automatic multiple
Position；When controller 1 controls electromagnetic switching valve 28 again to be resetted, pneumatic automatic window breaking device 8 regains air pressure, and then makees again
Go out brokenly window action.
With reference to Fig. 8, the vehicle window detection components whether ruptured for detecting vehicle window 9 are installed in the side wall of vehicle window 9；Vehicle window is examined
It includes the both sides of the edge that opposition is set to the glass 32 of vehicle window 9 to survey component, and is sent out for the light of light-conductive media with the glass of vehicle window 9 32
Emitter 29 and optical receiver 30；Optical transmitting set 29, optical receiver 30 are electrically connected with controller 1；When glass 32 ruptures so that
Optical receiver 30 can not receive the optical signal 31 that optical transmitting set 29 is sent out, and then the output signal of optical receiver 30 can change
Become；Controller 1 judges whether glass 32 ruptures according to the output signal of optical receiver 30.
Therefore, the operation principle and operating method of the present embodiment are：
S1：Passenger operation controller 1 is open-minded to control the first solenoid valve 3, so that the high pressure gas in gas tank 2 is entered pneumatic automatic
Window breaker 8 is to drive its action；
