[0001] The utility model belongs to the technical field of window breakers, and particularly relates to a window breaker for passenger cars. Background Art
[0002] With the widespread use of hidden door handles in domestic passenger cars, how to escape in time or rescue the people in the car in case of an accident has become a focus issue. Special electric control window breakers are generally used in domestic commercial buses as emergency escape tools to break the windows and establish an escape passage. However, due to the differences in the design and usage conditions between commercial buses and passenger cars, the window breakers suitable for commercial vehicles are not applicable to the usage environment of passenger cars. Content of the Utility Model
[0003] In view of this, the purpose of the utility model is to provide a window breaker for passenger cars to overcome the deficiencies of the prior art. The window breaker has a small overall dimension, which is convenient for arrangement, installation and use among different vehicles.

[0029] Embodiment 1:
[0030] Refer to Figure 1 , Figure 2 and Figure 7, the first structural schematic diagram of a window breaker for a passenger car provided in this embodiment includes a main body 1, an electronically controlled gas generator 2, a first safety component 3, and a limiting mechanism 4.
[0031] A launch hole 101 is provided at the bottom of the main body 1. A slidable impact head 5 is arranged in the launch hole 101. Its tip is processed with hard alloy material. The window breaking operation is realized by quickly moving and impacting the vehicle window glass to break it after the product works. The impact head 5 is fixed in the launch hole 101 through the first safety component 3. The limiting mechanism 4 is arranged at the opening of the launch hole 101. The electronically controlled gas generator 2 is arranged on the side of the main body 1 through double fixing pins 21 and is communicated to the launch hole 101 behind the impact head 5 through an air passage 6. The fixed pin fixing structure is more convenient and cost-saving. After the electronically controlled gas generator 2 operates to generate gas, the gas impacts the impact head 5 to make it abut against the limiting mechanism 4, and the front end of the impact head 5 extends out of the launch hole 101.
[0032] The first safety component 3 adopts a component that will automatically fail when subjected to a force exceeding a certain value, such as fragile pins and plastic and other components. In this embodiment, a fragile pin is adopted. A waterproof film 7 is arranged at the opening of the launch hole 101 for moisture-proof and waterproof protection of the interior of the product, ensuring that parts such as the impact head 5 do not rust.
[0033] During operation, after the electronically controlled gas generator 2 receives the start electrical signal, the gas-producing agent inside it burns and can generate a certain amount of gas. The gas expands in a closed space and advances along the air passage 6 to push the impact head 5. At this time, the first safety component 3 is damaged by the gas impact force and loses its fixed state with the impact head 5, resulting in the rapid downward movement of the impact head 5, abutting against the limiting mechanism 4. At the same time, the front end of the impact head 5 passes through the lower waterproof film 7 to perform the window breaking operation.
[0034] The structure of Embodiment 1 is relatively simple and practical. However, since there is a large amount of energy in the impact head 5 after the electronically controlled gas generator 2 generates gas, it is very likely that the impact head 5 still has a large amount of energy after breaking the window, which has an adverse impact on the structure of the product and may cause flying objects. Therefore, based on the above product structure, the product structures of the following two embodiments can be derived.
[0035] Embodiment 2:
[0036] Refer to Figure 3 and Figure 4, the second structural schematic diagram of the window breaker for passenger cars provided in this embodiment is different in that: an extension hole 102 is provided on the inner wall of the launch hole 101 behind the impact head 5, and a slidable piston block 8 is arranged in the extension hole 102. The piston block 8 is fixed in the extension hole 102 through a second safety component 9. The electronically controlled gas generator 2 is connected to the extension hole 102 behind the piston block 8 through an air duct 6. After the electronically controlled gas generator 2 operates, it generates gas to impact the piston block 8 to move a specified distance, and the piston block 8 pushes the impact head 5 downward.
[0037] By adding the design of the piston block 8, the impact head 5 becomes a non-continuously stressed state. After pushing the piston block 8 to move a specified distance in place, it no longer pushes against the impact head 5, and the impact head 5 no longer receives a thrust force. In this way, the remaining energy of the impact head 5 after breaking the window can be greatly reduced, and the reliability and safety of the product can be improved.
[0038] In order to improve the stable and reliable power transmission, a first inclined surface 501 is provided at the tail of the impact head 5, and the piston block 8 can abut against the first inclined surface 501 to push the impact head 5 downward by moving a specified distance. A second inclined surface 801 is also provided at the front end of the piston block 8, which can make the piston block 8 push the impact head 5 more smoothly.
[0039] Embodiment 3:
[0040] Referring to Figure 5 and Figure 6 , the third structural schematic diagram of the window breaker for passenger cars provided in this embodiment further includes a connecting rod 10. Both ends of the connecting rod 10 are respectively hinged to the piston block 8 and the impact head 5. The piston block 8 drives the connecting rod 10 to push the impact head 5 downward by moving a specified distance. The launch hole 101 and the extension hole 102 are perpendicular to each other, making the linkage smoother.
[0041] Similar to Embodiment 2, after the piston block 8 moves a specified distance in place, it no longer pushes against the impact head 5 through the connecting rod 10, and the impact head 5 no longer receives a thrust force. Moreover, the length of the connecting rod 10 is limited, which can further limit the moving distance of the impact head 5.
[0042] Secondly, due to the existence of the connecting rod 10, the piston block 8 and the impact head 5 are interlocked and linked, and only one first safety component 3 or second safety component 9 needs to be provided. Therefore, only the second safety component 9 is provided in this embodiment.
[0043] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
