[0035] Next, refer to Figures 1 - 5 to describe the window breaker 103 according to an embodiment of the present utility model. The window breaker 103 can achieve rapid window breaking, greatly improve the window breaking efficiency, is convenient and fast to use, provides convenience for rescue or self-rescue, and is conducive to rapid escape.

[0036] As Figures 1 - 5 shown, the window breaker 103 according to an embodiment of the present utility model includes: a housing 1, a window breaking structure 2, and a driving structure 3. It should be noted that the window breaker 103 can be used in any emergency scenarios such as vehicle accidents and fire escapes where it is necessary to quickly break the glass.

[0037] The housing 1 is used to install and protect the window-breaking structure 2 and the driving structure 3. The interior of the housing 1 is hollow to form an installation cavity 11. The window-breaking structure 2 is installed within the installation cavity 11. Thus, the housing 1 can protect the window-breaking structure 2, preventing it from being affected by the outside world and supporting its movement within the installation cavity 11. One end of the installation cavity 11 is provided with an ejection port 111. The window-breaking structure 2 can be ejected from the ejection port 111. It can be understood that the housing 1 should have sufficient strength and stiffness to withstand the impact force generated during window-breaking. At the same time, the outer surface of the housing 1 should be anti-slip to prevent the user's hand from slipping off during the use of the window breaker 103, which may affect the window-breaking effect.

[0038] The window-breaking structure 2 is mainly used for breaking windows. The window-breaking structure 2 includes a window-breaking part 21, an elastic energy storage member 22, and a movable block 23. The window-breaking part 21 is the component that directly breaks the glass window. As Figure 3 shown, the window-breaking part 21 can be configured as a cone to improve the effect of piercing through the car window. One end of the elastic energy storage member 22 is connected to the window-breaking part 21 and the other end is connected to the movable block 23. The elastic energy storage member 22 can store energy, having a certain elastic stretching force. When compressed or stretched, it can store energy and, when releasing the energy, push the window-breaking part 21 to eject at high speed. The movable block 23 can move within the installation cavity 11 to gradually store energy in the elastic energy storage member 22.

[0039] Furthermore, the driving structure 3 is used to drive the movable block 23 to move relative to the window-breaking part 21 and store energy in the elastic energy storage member 22, and after the energy stored in the elastic energy storage member 22 reaches the set value, push the window-breaking part 21 to eject from the ejection port 111 for window-breaking.

[0040] Specifically, the driving structure 3 can provide power for the window breaker 103 to drive the movable block 23 to move. In practice, when the window breaker 103 needs to be used, the driving structure 3 can be started. The driving structure 3 drives the movable block 23 to gradually approach the window-breaking part 21, causing the elastic energy storage member 22 to be gradually compressed and store energy. When the energy stored in the elastic energy storage member 22 reaches the set value, the energy can be quickly released to push the window-breaking part 21 to eject from the ejection port 111 of the housing 1 at high speed, hitting and penetrating the glass to achieve window-breaking.

[0041] In the actual design, the driving structure 3 can be set as a driving motor to provide power, enabling the user to easily use the window breaker 103 to break the window without effort. That is, the user does not need to manually provide power to use the window breaker 103. Compared with the traditional mechanical window breaker 103, the window-breaking efficiency is greatly improved, and it is convenient and fast to use, providing convenience for rescue or self-rescue and facilitating quick escape.

[0042] According to the window breaker 103 of the embodiment of the present utility model, by setting the driving structure 3 to drive the movable block 23 to move relative to the window breaking part 21 and store energy in the elastic energy storage member 22, manual driving by the user is not required, which improves the labor-saving effect. And after the energy stored in the elastic energy storage member 22 reaches the set value, it can push the window breaking part 21 to pop out from the ejection port 111, realizing rapid window breaking, greatly improving the window breaking efficiency, being convenient and fast to use, providing convenience for rescue or self-rescue, and being conducive to rapid escape.

[0043] In some embodiments, the window breaker 103 further includes a limiting member 4. The limiting member 4 is movably installed at the ejection port 111. The limiting member 4 is connected with an elastic holding member, and the elastic holding member is used to push the limiting member 4 to limit and press against the window breaking part 21.

[0044] Specifically, the limiting member 4 is used to limit the elastic energy storage member 22. When the window breaker 103 is not in use, it blocks the accidental ejection of the elastic energy storage member 22 from the ejection port 111, improving the safety of using the window breaker 103. The limiting member 4 is movably installed at the ejection port 111, that is, the limiting member 4 can move flexibly at the ejection port 111 to close or open the ejection port 111. When the window breaker 103 is not in use, the elastic holding member can provide a thrust for the limiting member 4 to push the window breaking part 21 into the ejection port 111, so that the limiting member 4 can tightly press against the window breaking part 21, thus maintaining a stable state, being installed at the ejection port 111 and blocking in front of the window breaking part 21.

[0045] Among them, the thrust of the elastic holding member on the limiting member 4 needs to be large enough so that when the window breaker 103 is not in use, the elastic holding member can be stably installed at the ejection port 111 and press against the window breaking part 21. At this time, the driving force of the limiting member 4 is equivalent to the energy stored in the elastic energy storage member 22, just enough to block the ejection of the window breaking part 21. When using the window breaker 103, the driving structure 3 drives the movable block 23 to move towards the window breaking part 21, and the elastic energy storage member 22 begins to gradually store energy. As the stored energy gradually increases, after the energy stored in the elastic energy storage member 22 is greater than the driving force of the elastic holding member on the limiting member 4, it pushes the window breaking part 21 to pop out from the ejection port 111. At this time, the limiting member 4 is pushed by the window breaking part 21 to leave the ejection port 111, allowing the window breaking part 21 to smoothly pop out from the ejection port 111.

[0046] In some embodiments, the limiting member 4 is rotatably installed on the housing 1 through a rotating shaft 6, and the elastic holding member is configured as a torsion spring 5 sleeved outside the rotating shaft 6.

[0047] Specifically, as Figure 3As shown, the limit member 4 is rotatably connected to the end of the shell 1 through the rotating shaft 6, that is, the limit member 4 can move around the rotating shaft 6 relative to the shell 1 to achieve closing the ejection outlet 111 or opening the ejection outlet 111, wherein the torsion spring 5 is sleeved on the outside of the rotating shaft 6, one end of which is connected to the shell 1, and the other end is connected to the limit member 4, so that the limit member 4 can be kept in a stable state by the torsion force of the torsion spring 5, that is, the torsion force of the torsion spring 5 is equivalent to the stored force of the elastic force storage member 22, and the limit member 4 can press the broken window part 21 to prevent it from popping out, and when the stored force of the elastic force storage member 22 is greater than the torsion force of the torsion spring 5, the limit member 4 can be pushed by the broken window part 21 to overcome the torsion force of the torsion spring 5 and rotate around the rotating shaft 6, thereby allowing the broken window part 21 to pass through the ejection outlet 111.

[0048] Therefore, by installing the limit member 4 through the rotating shaft 6 and the torsion spring 5, the structural compactness of the window breaker 103 is improved, making the structure simpler and more reliable, and the torsion spring 5 has stable performance and a long service life, which can ensure that the window breaker 103 still has reliable performance after repeated use. In actual design, the torque size of the torsion spring 5 can be designed and adjusted according to actual needs to adapt to the force storage size of the elastic force storage member 22.

[0049] In some embodiments, Figure 5 As shown, there are two limit members 4, which are symmetrically distributed at the ejection outlet 111, that is, the shape and size of the two limit members 4 are adapted to the shape and size of the ejection outlet 111, so that they can be symmetrically distributed on both sides of the ejection outlet 111 to close the ejection outlet 111. In this way, the window breaker 103 is more balanced when subjected to force, preventing the window breaker 103 from twisting or deflecting, which affects the window breaking effect.

[0050] Among them, Figure 2 As shown, the shell 1 is constructed in a cylindrical shape to facilitate the user's grip, so that the ejection outlet 111 is constructed in a circular shape, and the limiting member 4 is constructed as a semicircular plate to adapt to the shape of the ejection outlet 111, and the two semicircular plates are installed on the shell 1 through the rotating shaft 6 and the torsion spring 5, thereby, the two limiting members 4 can be spliced ​​into a circle in a closed state to jointly close the ejection outlet 111 and effectively block the broken window portion 21. When the elastic force storage member 22 pushes the broken window portion 21 to pop out from the ejection outlet 111, the two semicircular plates can simultaneously rotate outward around the rotating shaft 6 to open the ejection outlet 111.

[0051] In some embodiments, the movable block 23 is slidably installed in the installation cavity 11 , and the movable block 23 is suitable for linear motion relative to the broken window portion 21 to approach or move away from the broken window portion 21 .

[0052] Specifically, the installation cavity 11 can be provided with slide rails or other guiding members so that the movable block 23 can slide within the installation cavity 11 and move linearly within the installation cavity 11, ensuring the movement stability of the movable block 23. In practice, when the movable block 23 gradually approaches the window-breaking part 21, one end of the window-breaking part 21 presses against the limiting member 4, causing one end of the elastic energy storage member 22 to be fixed, while the other end gradually approaches the window-breaking part 21 as the movable block 23 moves. Thus, the elastic energy storage member 22 is gradually compressed for energy storage. When the set energy storage value is reached, the elastic energy storage member 22 pops out at high speed. At this time, the movable block 23 stops moving and is in a relatively stable position.

[0053] In some embodiments, the driving structure 3 includes a driving member 31. The driving member 31 is connected with a driving gear 32. The movable block 23 is provided with a driven rack portion 231. The driving gear 32 meshes with the driven rack portion 231 and is adapted to drive the driven rack portion 231 to move linearly.

[0054] That is to say, the driving member 31 can drive the driving gear 32 to rotate. The driving gear 32 rotates to drive the driven rack portion 231 to move linearly. During the movement of the driven rack portion 231, the movable block 23 is driven to move linearly within the installation cavity 11 and approach the window-breaking part 21 to realize the energy storage of the elastic energy storage member 22.

[0055] Specifically, as Figure 2 shown, the driving member 31 can be configured as a driving motor. The motor shaft of the driving motor is connected with the driving gear 32 so that the motor shaft can drive the driving gear 32 to rotate synchronously when rotating. Among them, the movable block 23 can be configured as a square block. An installation groove can be formed on its top surface. The driving gear 32 and the driven rack portion 231 are installed in the installation groove, and the installation groove is open upward so that the driving member 31 can extend into the installation groove to be connected with the driving gear 32.

[0056] It can be understood that the length of the driven rack portion 231 is the range within which the movable block 23 can move. When the driving gear 32 moves from one end of the driven rack portion 231 to the other end, the movement of the movable block 23 is completed. In practice, the driving motor can be rotated forward and backward to realize the movement of the movable block 23 away from or close to the window-breaking part 21.

[0057] In some embodiments, the window breaker 103 further includes: a power supply 7. The power supply 7 is electrically connected with the driving member 31 and is used to supply power to the driving member 31. The power supply 7 provides electrical energy to the driving member 31 so that the driving member 31 can stably provide power, thereby improving the reliability of the window breaker 103.

[0058] The window breaker 103 further includes: a control switch 8. The control switch 8 is pressably installed on the housing 1, and the control switch 8 is connected with the driving member 31 to control the opening or closing of the driving member 31.

[0059] Specifically, as Figure 2 shown, the housing 1 is provided with a mounting hole for mounting the control switch 8, so that the user can press the control switch 8 externally. When the control switch 8 is pressed, the control driving member 31 is turned on. At this time, the circuit is closed, and the driving member 31 can drive the movable block 23 to move, and thus the window-breaking operation can be realized. Therefore, the window can be broken by pressing the control switch 8 with one key, making the use of the window breaker 103 more convenient.

[0060] In actual use, the power supply 7 can be charged and can also charge other electrical components, and can be used as an emergency power supply as a power bank, improving the use performance of the window breaker 103.

[0061] In some embodiments, the power supply 7 is installed at one end of the housing 1, and the ejection port 111 is formed at the other end of the housing 1.

[0062] Specifically, as Figure 2 shown, the power supply 7 and the ejection port 111 are respectively distributed at both ends of the housing 1. As shown in the left-right direction in the figure, the power supply is installed at the left end of the housing 1, and the ejection port 111 is formed at the right end of the housing 1. In this way, the power supply 7 is far away from the ejection port 111 and the window-breaking part 21, reducing the impact and vibration generated by the window-breaking operation on the power supply 7, and facilitating the replacement and maintenance of the power battery 7.

[0063] The present utility model also proposes an instrument panel assembly 100.

[0064] According to the instrument panel assembly 100 of the embodiment of the present utility model, the window breaker 103 of any one of the above embodiments is provided. The instrument panel body 101 is provided with a mounting bracket 102, and the window breaker 103 is detachably mounted on the mounting bracket 102. That is, the mounting bracket 102 can be formed with a mounting opening adapted to the housing 1 of the window breaker 103, and the window breaker 103 can be mounted on the mounting bracket 102 through the mounting opening. When in need of use, it can be removed from the mounting bracket 102 to realize the disassembly of the window breaker 103. Therefore, the safe storage and quick disassembly of the window breaker 103 on the instrument panel assembly 100 are realized.

[0065] Specifically, as Figure 1 shown, a mounting bracket 102 is provided on the surface of the instrument panel body 101. The mounting bracket 102 can be configured as a clamp, and the clamp can be opened at a certain angle to form a mounting opening, so that the window breaker 103 can be clamped in the clamp to realize the fixation of the window breaker 103. Of course, the window breaker 103 can also be mounted on the mounting bracket 102 by other connection methods such as bolt connection, improving the installation stability and reliability of the window breaker 103.

[0066] Among them, it should be noted that the window breaker 103 can also be installed on the car door or placed in the storage box for easy access by the user, thus improving convenience.

[0067] The present utility model also provides a vehicle.

[0068] The vehicle according to the embodiment of the present utility model is provided with the window breaker 103 or the instrument panel assembly 100 of any one of the above embodiments. Among them, by setting the driving structure 3 to drive the movable block 23 to move relative to the window breaking part 21 and store energy in the elastic energy storage member 22, manual driving by the user is not required, which improves the labor-saving effect. And after the energy stored in the elastic energy storage member 22 reaches the set value, it can push the window breaking part 21 to pop out from the ejection port 111, realizing rapid window breaking, greatly improving the window breaking efficiency, being convenient and fast to use, providing convenience for rescue or self-rescue, and being conducive to rapid escape.
