[0021] In the present invention, reference is made to Figure 4 In this state, the firing pin 300 is in the window-breaking position and the driving device 500 drives the sliding seat 200 to be linked with the firing pin 300; Figure 5 In this state, the driving device 500 drives the sliding seat 200 to drive the firing pin 300 into the charging position; Figure 6 In this state, the linkage assembly 600 is triggered by the trigger part 110 and releases the linkage with the firing pin 300. The firing pin 300 enters the window breaking position again under the action of the first elastic member 400, thereby breaking the car window 820.
[0022] Reference Figure 3-Figure 6 As a preference, the sliding seat 200 is provided with a first slide groove 220 and a second slide groove 230 which are arranged on both sides of the movable groove 210 and are connected to the movable groove 210, the firing pin 300 is provided with a linkage groove 310, and the linkage assembly 600 includes a first slider 610, a second slider 620, a second elastic member 630 and a third elastic member 640; the first slider 610 is arranged in the first slide groove 220, the second slider 620 is arranged in the second slide groove 230; the second elastic member 630 abuts between the first slider 610 and the first slide groove 220, and the third elastic member 640 The elastic member 640 abuts between the second slider 620 and the second slide groove 230; the first slider 610 and the second slider 620 can be inserted into the linkage groove 310 when the firing pin 300 is in the window-breaking position, so that the sliding seat 200 is linked with the firing pin 300, so that the firing pin 300 enters the power storage position under the drive of the driving device 500, or the first slider 610 and the second slider 620 can be triggered by the trigger part 110 when the firing pin 300 is in the power storage position and disengaged in the linkage groove 310, so that the firing pin 300 breaks the car window 820 under the action of the first elastic member 400.

At this time, the first slider 610 and the second slider 620 enter the linkage groove 310 on the firing pin 300, so that the sliding seat 200 and the firing pin 300 are in a linkage state. Then, the driving device 500 drives the sliding seat 200 to move from front to rear, and the firing pin 300 moves backward synchronously, and the first elastic member 400 is in a compressed and force-accumulating state until it reaches the end of the stroke. Figure 5 state (the linkage assembly 600 is not triggered by the trigger part 110); when the driving device 500 receives the window breaking command, it will drive the sliding seat 200 to continue to move backward until the linkage assembly 600 is triggered by the trigger part 110, that is, the first slider 610 and the second slider 620 are disengaged from the linkage groove 310 on the firing pin 300. At this time, the firing pin 300 can move in the front and rear directions relative to the sliding seat 200. Further, the first elastic member 400 loses the external force and recovers its deformation, which will push the firing pin 300 to move forward until the firing pin 300 is partially located outside the shell 100, and finally the car window 820 is broken.

[0031] The present invention also provides an automatic window breaking system, comprising a controller 710, an environment detector 720, an occupant detector 730, an energy storage component 740, and the aforementioned window breaker; The environmental detector 720 is installed in the vehicle and is electrically connected to the controller 710 for detecting environmental factors in the vehicle; The occupant detector 730 is mounted on the seat and electrically connected to the controller 710 to detect whether there is an occupant on the seat; The energy storage assembly 740 is installed in the vehicle and is electrically connected to the controller 710 . The energy storage assembly 740 is connected to the vehicle power supply 810 . The window breaker is mounted on the vehicle body and is electrically connected to the controller 710 via a cable 930 , and is used to break the vehicle window 820 ; The controller 710 may control the window breaker to break the vehicle window 820 when the environment detector 720 detects that the environmental factors in the vehicle body reach a preset value and the occupant detector 730 detects that there is an occupant on the seat. The environment detector 720 is configured as a water level sensor and / or a smoke sensor, and the occupant detector 730 is configured as a gravity sensor.
[0032] Specifically, when in use, when a vehicle has an accident, such as being immersed in water, impacted, or spontaneously combusted, by setting the environment detector 720 to a water level sensor 721 and / or a smoke sensor 722, it is possible to detect whether the vehicle is immersed in water or whether a fire has occurred due to an impact, etc. At the same time, the occupant detector 730 is used to detect whether there are occupants on the seats. When it is detected that there are occupants in the vehicle and smoke is generated and / or the vehicle is immersed in water, after a preset delay time (e.g., 10 seconds), if the door is not detected to be open, it is determined that the occupant is disabled or unable to break the window to escape. At this time, the controller 710 sends a signal to the window breaker. Window breaking command, after receiving the window breaking command, the window breaker breaks the vehicle window 820 to facilitate the user's emergency escape; it should be noted that the present invention is provided with an energy storage component 740. When no traffic accident occurs, the vehicle power supply 810 charges the energy storage component 740 to keep the energy storage component 740 in a fully charged state at all times.
