With reference to fig. 3, 4 and 5, the glass baffle 13 is mounted in the bottom wall of the window 9, the bottom wall of the window 9 having a receiving groove 11 for mounting thereof; the width of the accommodating groove 11 is as close as possible to the width of the window 9. The glass baffle 13 comprises a bottom plate 14 and a rotating plate rotatably connected to the top side of the bottom plate 14, and two side walls of the accommodating groove 11 are provided with sliding grooves (not shown) for mounting the bottom plate 14, so that the bottom plate 14 can slide up and down along the depth direction of the accommodating groove 11 after being in sliding fit with the sliding grooves; the top side of the bottom plate 14 is provided with a limiting plate 15 for preventing the rotating plate from rotating towards the direction away from the vehicle window 9; the rotating plate comprises a first plate body 16 and a second plate body 17, the first plate body 16 is rotatably connected with the second plate body 17, and the connecting point is lower than the limiting plate 15.

Example 2:
this example is substantially the same as example 1, except that:
referring to fig. 7A, a position detecting assembly for detecting the position of the deflecting arm 7 is disposed on the base 6, and the position detecting assembly is electrically connected to the controller 1. In this embodiment, the position detecting assembly employs a proximity switch 26, and a metal body 27 capable of being detected by the proximity switch 26 is correspondingly disposed on the deflection arm 7; when the deflecting arm 7 is in the vertical position, the metal body 27 approaches and triggers the proximity switch 26; the proximity switch 26 sends a high level switching signal to the controller 1. When the deflecting arm 7 is rotated to the horizontal state, the metal body 27 is separated from the proximity switch 26, and the proximity switch 26 transmits a low-level switching signal to the controller 1.
Referring to fig. 7B, an electromagnetic switching valve 28 is connected to an air inlet of the pneumatic automatic window breaker 8, and the electromagnetic switching valve 28 is electrically connected to the controller 1. When the controller 1 controls the electromagnetic switching valve 28 to act, the air pressure of the pneumatic automatic window breaker 8 disappears, and the pneumatic automatic window breaker automatically resets; when the controller 1 controls the electromagnetic switching valve 28 to reset again, the pneumatic automatic window breaker 8 regains the air pressure, and then the window breaking action is performed again.
Referring to fig. 8, a window detecting assembly for detecting whether the window 9 is broken is installed in a side wall of the window 9; the vehicle window detection assembly comprises a light emitter 29 and a light receiver 30 which are oppositely arranged on two side edges of a glass 32 of the vehicle window 9 and take the glass 32 of the vehicle window 9 as a light guide medium; the light emitter 29 and the light receiver 30 are both electrically connected with the controller 1; when the glass 32 is broken, the optical receiver 30 cannot receive the optical signal 31 emitted by the optical emitter 29, and the output signal of the optical receiver 30 changes; the controller 1 determines whether the glass 32 is broken or not based on the output signal of the light receiver 30.
Therefore, the working principle and the operation method of the embodiment are as follows:
s1: the passenger operates the controller 1 to control the first electromagnetic valve 3 to be opened, so that high-pressure gas in the gas tank 2 enters the pneumatic automatic window breaker 8 to drive the pneumatic automatic window breaker to act;
