Description

Technical Field

[0001] This utility model relates to the field of vehicle safety technology, and in particular to a window breaker and an automatic window breaking system. Background Technology

[0002] With the development of automobiles, there are more and more cars on the road, and the road conditions are becoming more and more complex. However, the skill level of drivers varies, leading to an increasing probability of traffic accidents. Electric vehicles, in particular, are prone to battery fires or even explosions in accidents due to current technology limitations. In addition, some cars may have doors that cannot be unlocked in some accidents. Without a professional window breaker, the chances of survival for the occupants will be greatly reduced. Furthermore, even if a window breaker is provided in the car, in such an emergency, occupants may need a long time to search for the window breaker due to shock or injury, making it even more difficult to use the window breaker to break the window and escape.

[0003] Chinese invention patent 2023114477636 (An Electrically Controlled Window Breaking System) discloses an electrically controlled window breaker. This electrically controlled window breaker uses a pull rod, torsion spring, and spring to drive a pin to store force. When the pull rod reaches the end of its stroke, it is triggered, which releases the pin to break the window. However, this type of window breaker is not only relatively complex, but the pull rod also relies on the deformation force of the torsion spring to hook the pin, which can lead to failure to hook the pin. In addition, the overall structure is large and requires more space in the car door. Therefore, there is an urgent need for a window breaker and an automatic window breaking system to solve the above problems. Utility Model Content

[0044] Reference Figures 1 to 8 This utility model provides a window breaker, including a housing 100, a sliding seat 200, a firing pin 300, a first elastic element 400, a driving device 500, and a linkage component 600;

[0045] A trigger part 110 is provided on the housing 100;

[0046] The sliding seat 200 is slidably disposed within the housing 100 and has a movable groove 210 thereon;

[0047] The firing pin 300 is inserted into the movable slot 210 and has a switchable window-breaking position and a power-accumulating position;

[0048] The first elastic element 400 abuts between the housing 100 and the firing pin 300;

[0049] The drive device 500 is disposed inside the housing 100 and connected to the sliding seat 200, and is used to drive the sliding seat 200 to reciprocate in the front-back direction;

[0050] The linkage component 600 is mounted on the slide seat 200 and is used to link the slide seat 200 and the firing pin 300.

[0051] The linkage component 600 can be linked with the firing pin 300 when the firing pin 300 is in the window breaking position, so that the firing pin 300 enters the charging position under the drive of the drive device 500, or the linkage component 600 can be triggered by the triggering part 110 when the firing pin 300 is in the charging position and the linkage with the firing pin 300 can be released, so that the firing pin 300 breaks the window 820 under the action of the first elastic member 400.

[0052] In this utility model, 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 work in conjunction with the firing pin 300; refer to Figure 5 In this state, the drive unit 500 drives the sliding seat 200 to move the firing pin 300 into the storage position; refer to Figure 6 In this state, the linkage component 600 is triggered by the triggering part 110 and the linkage between it and the firing pin 300 is released. Under the action of the first elastic element 400, the firing pin 300 re-enters the window breaking position, thereby breaking the car window 820.

[0053] Reference Figures 3-6 Preferably, the sliding seat 200 is provided with a first sliding groove 220 and a second sliding groove 230 that are arranged on both sides of the movable groove 210 and communicate with the movable groove 210. The firing pin 300 is provided with a linkage groove 310. 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 disposed in the first sliding groove 220, and the second slider 620 is disposed in the second sliding groove 230. The second elastic member 630 abuts against the first slider 610 and the first sliding groove 220. The third elastic member 640... The elastic element 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 charging position under the drive of the drive device 500, or the first slider 610 and the second slider 620 can be triggered by the triggering part 110 and disengage from the linkage groove 310 when the firing pin 300 is in the charging position, so that the firing pin 300 breaks the car window 820 under the action of the first elastic element 400.

[0054] Specifically, the firing pin 300 is... Figure 4 The state is switched to Figure 5 In the state of [unclear], the drive device 500 first drives the sliding seat 200 to move from back to front until it reaches the end of its stroke. At this time, the first slider 610 and the second slider 620 enter the linkage groove 310 on the firing pin 300, making the sliding seat 200 and the firing pin 300 linked. Then, the drive device 500 drives the sliding seat 200 to move from front to back, and the firing pin 300 moves backward synchronously, causing the first elastic element 400 to be in a compressed and stored state until [unclear]. Figure 5 In the state where the linkage component 600 is not triggered by the triggering part 110, when the drive device 500 receives the window-breaking command, it will drive the sliding seat 200 to continue moving backward until the linkage component 600 is triggered by the triggering part 110, that is, the first slider 610 and the second slider 620 disengage from the linkage groove 310 on the firing pin 300. At this time, the firing pin 300 can move in the front-back direction relative to the sliding seat 200. Furthermore, the first elastic element 400 loses the external force and deforms and recovers, which will push the firing pin 300 forward until the firing pin 300 is partially outside the housing 100, and finally break the window 820.

[0055] Reference Figures 3-8In some embodiments, the firing pin 300 is provided with a first limiting ring 320 and a second limiting ring 330 arranged at intervals along its length direction, and a linkage groove 310 is formed between the first limiting ring 320 and the second limiting ring 330. The first slider 610 is provided with a first inclined surface 611 on its front side, a first straight surface 612 on its rear side, and a second inclined surface 613 located on one side of the first straight surface 612. The first inclined surface 611 faces downward to the front side, and the second inclined surface 613 faces downward to the rear side. Further, the second slider 620 is provided with a third inclined surface 621 on its front side, a second straight surface 622 on its rear side, and a fourth inclined surface 623 located on one side of the second straight surface 622. The third inclined surface 621 faces upward to the front side, and the fourth inclined surface 623 faces upward to the rear side.

[0056] Specifically, when the window breaker is... Figure 6 The state is switched to Figure 4 When the sliding seat 200 moves from back to front under the drive of the drive device 500, the first inclined surface 611 on the first slider 610 will abut against the second limiting ring 330, causing the first slider 610 to be pushed to compress the second elastic element 630. When the first slider 610 passes the second limiting ring 330, the first slider 610 will enter the linkage groove 310 under the action of the second elastic element 630. During the process of the drive device 500 driving the sliding seat 200 to move backward, the firing pin 300 will move backward synchronously through the abutment of the first straight surface against the side wall of the linkage groove 310. It should be noted that the movement process of the second slider 620 is the same as that of the first slider 610, which will not be described in detail here. This causes the linkage component 600 and the firing pin 300 to enter the linkage state. When the window breaker moves from back to front, the first inclined surface 611 on the first slider 610 will abut against the second limiting ring 330, causing the first slider 610 to be pushed against the second elastic element 630. Figure 4 The state is switched to Figure 5 When the first slider 610 is in the state of being in contact with the second inclined surface 613 on the first slider 610, it will abut against the trigger part 110 on the housing 100, thus pushing the first slider 610 out of the linkage groove 310 and compressing the second elastic member 630. The firing pin 300 can then be pushed by the first elastic member 400 to be partially outside the housing 100, thus breaking the window 820.

[0057] Reference Figures 3-6 In some embodiments, the first straight surface 612 is located in the middle section behind the first slider 610, and the second inclined surface 613 is set as two and arranged on both sides of the first straight surface 612. The trigger part 110 is set as two and corresponds one-to-one with the second inclined surface 613. This arrangement can make the first slider 610 slide more smoothly in the first slide groove 220 and avoid the situation where the linkage component 600 and the firing pin 300 fail to link.

[0058] Reference Figures 3-6In some embodiments, a window breaker further includes a first cover plate 240 and a second cover plate 250. The first cover plate 240 is connected to the sliding seat 200 via a first detachable structure 260 and closes the first sliding groove 220. The second cover plate 250 is connected to the sliding seat 200 via a second detachable structure 270 and closes the second sliding groove 230. As a preferred embodiment of the first detachable structure 260 and the second detachable structure 270, the first detachable structure 260 and / or the second detachable structure 270 are configured as a third bolt connection structure.

[0059] Reference Figures 3-6 In some embodiments, the sliding seat 200 is provided with a clearance groove 280 that communicates with the movable groove 210, the first sliding groove 220 and the second sliding groove 230, for clearance of the triggering part 110.

[0060] Reference Figures 3-6 In some embodiments, the drive device 500 includes a motor 510, a reduction gear set 520, and a lead screw 530. The motor 510 is connected to the input end of the reduction gear set 520, the lead screw 530 is rotatably disposed within the housing 100 and connected to the output end of the reduction gear set 520, and the sliding seat 200 is threadedly connected to the lead screw 530. Furthermore, a window breaker also includes a guide rod 540 disposed within the housing 100. The guide rod 540 is arranged opposite to the lead screw 530, one end of the sliding seat 200 is threadedly connected to the lead screw 530, and the other end of the sliding seat 200 is slidably sleeved on the guide rod 540. Specifically, the rotational speed output by the motor 510 is reduced by the reduction gear set 520, which drives the lead screw 530 to rotate forward or backward. The sliding seat 200 is limited by the guide rod 540, which can convert the rotational motion of the lead screw 530 into linear motion of the sliding seat 200 in the front-back direction.

[0061] Reference Figures 2-6 The housing 100 includes a front shell 120 and a bottom shell 130. The front shell 120 is connected to the bottom shell 130 through a first bolt connection structure 910. The two together form an installation cavity. The sliding seat 200, the firing pin 300, the first elastic element 400, the driving device 500, and the linkage assembly 600 are installed in the installation cavity. Furthermore, the front shell 120 and / or the bottom shell 130 are connected to the vehicle door or the vehicle body through a second bolt connection structure 920.

[0062] This utility model also provides an automatic window breaking system, including a controller 710, an environmental detector 720, an occupant detector 730, an energy storage component 740, and the aforementioned window breaker;

[0063] An environmental detector 720 is installed inside the vehicle and electrically connected to the controller 710 to detect environmental factors inside the vehicle.

[0064] The occupant detector 730 is installed on the seat and electrically connected to the controller 710, and is used to detect whether there is an occupant on the seat;

[0065] The energy storage component 740 is installed inside the vehicle and electrically connected to the controller 710. The energy storage component 740 is connected to the vehicle power supply 810.

[0066] The window breaker is installed on the vehicle body and is electrically connected to the controller 710 via cable 930, and is used to break the vehicle window 820;

[0067] The controller 710 can control the window breaker to break the window 820 when the environmental detector 720 detects that the environmental factors inside the vehicle body have reached a preset value and the occupant detector 730 detects that there is an occupant in the seat.

[0068] The environmental 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.

[0069] Specifically, in use, when a vehicle is involved in an accident, such as flooding, impact, or spontaneous combustion, the environmental detector 720 is configured as a water level sensor 721 and / or a smoke sensor 722 to detect whether the vehicle is flooded or has caught fire due to an impact. Simultaneously, the occupant detector 730 detects whether there are occupants in the seats. When both occupants are detected inside the vehicle and smoke is generated and / or the vehicle is flooded, after a preset delay (e.g., 10 seconds), if no door is detected opening, it is determined that the occupant is incapacitated or unable to escape through a window. At this time, the controller 710 sends a breaker signal to the window breaker. Upon receiving a window breaking command, the window breaker breaks the vehicle window 820 to facilitate emergency escape for the user. It should be noted that this invention includes an energy storage component 740. When no traffic accident occurs, the vehicle power supply 810 charges the energy storage component 740, ensuring it remains fully charged. If a short circuit occurs in the vehicle power supply 810, the electrical connection between the vehicle power supply 810 and the energy storage component 740 will be automatically severed to prevent any impact on the window breaking system. The energy storage component 740 is preferably a battery, but can also be a supercapacitor, etc., without limitation.

[0070] The advantages of this utility model are: the above structure can automatically break the car window in the event of a safety accident without the need for the occupants to break it manually, which greatly improves the safety of the vehicle and the survival rate of the occupants in an emergency. In addition, it has the advantages of compact structure and small size, which helps to reduce the need for door installation space.

[0071] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
