In order to escape as quickly as possible, people inside the vehicle usually use sharp objects to break the glass, such as escape hammers and window breakers.
[0003] Existing window breakers mainly use mechanical or electronic triggering. Due to vehicles falling into water, electronic triggering may experience delayed activation or failure, while mechanical triggering, once the window is broken, cannot be easily reset, making reuse difficult. Utility Model Content
[0004] The purpose of this utility model is to solve the aforementioned technical problems by providing a window breaker, a door assembly, and a vehicle, thereby improving the reusability and convenience of the window breaker.

[0031] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0032] In one embodiment, a window breaker is provided that can break glass by mechanically striking it. The window breaker can be reset after striking the glass and reused, making it more convenient and reusable. This is described in detail below.
[0033] like Figures 1-3As shown, the window breaker includes a housing 1, an impactor 2, a trigger 3, and a first elastic element 4. One end of the housing 1 is provided with a through hole 11, and the other end of the housing 1 is provided with a first end cap 5 and a limiting seat 6. The limiting seat 6 protrudes from the first end cap 5. One end of the impactor 2 extends movably out of the through hole 11, and the other end of the impactor 2 passes through the first end cap 5 and is connected to the trigger 3. The first elastic element 4 is disposed in the housing 1, and its two ends abut against the impactor 2 and the first end cap 5, respectively. When the trigger 3 abuts against the limiting seat 6, there is a gap between the impactor 2 and the glass, and the first elastic element 4 is in an energy storage state to restrict the movement of the impactor 2 in the housing 1. When the trigger 3 disengages from the limiting seat 6 and abuts against the first end cap 5, the first elastic element 4 drives the impactor 2 to strike and break the glass.
[0034] The impactor 2 is rotatable and / or linearly movable within the housing 1. After the trigger 3 rotates and disengages from the limiting seat 6, the impactor 2, driven by the first elastic element 4, moves linearly within the housing 1 until it reaches a preset position. The impactor 2 moves until it interferes with the glass, reaching the preset position to strike the glass and thus breaking it. In its initial position, the distance between the impactor 2 and the glass is not less than 10mm. It is understood that when the trigger 3 is positioned in the limiting seat 6, the gap between the tip 21 of the impactor 2 and the glass is not less than 10mm, which does not affect the normal movement of the glass.
[0035] The specific operation process of the window breaker is as follows: The window breaker is fixed in a designated position, which can be a car door, and the glass can be a car window. The trigger 3 positions the impactor 2 on the limiting seat 6. The impactor 2 compresses the first elastic element 4 inside the housing 1. The first elastic element 4 is in an energy storage state, and the tip 21 of the impactor 2 is away from the car window glass. When the vehicle is in danger and the window needs to be broken, the window breaker can be operated. The trigger 3 is disengaged from the limiting seat 6 by rotating at a certain angle. The trigger 3 can move away from the housing 1 and further compress the first elastic element 4 to increase mechanical potential energy. After the trigger 3 is released, it is pressed against the first end cover 5. The impactor 2 moves in a straight line in the housing 1, and the tip 21 of the impactor 2 reaches the preset position to strike the glass. Alternatively, the trigger 3 can be disengaged from the limiting seat 6 by rotating at a certain angle and then directly released to press against the first end cover 5. The tip 21 of the impactor 2 can still reach the preset position to strike the glass.
[0036] The trigger 3 can rotate away from the limiting seat 6 at an angle of 90°. The two ends of the trigger 3 extend radially to form the first end cap 5, so as to facilitate the operation of the trigger 3 and apply a pulling force to the trigger 3 to move it away from the housing 1, while improving the convenience of resetting the trigger 3.
[0037] By setting a limiting seat 6 on the housing 1, when the trigger 3 abuts against the limiting seat 6, there is a gap between the impact member 2 and the glass, and the first elastic member 4 is in an energy storage state to restrict the movement of the impact member 2 in the housing 1. When the trigger 3 disengages from the limiting seat 6 and abuts against the first end cover 5, the first elastic member 4 drives the impact member 2 to strike and break the glass. The trigger 3 can be flexibly operated to reset to the limiting seat 6, and the impact member 2 can be reused without dismantling the entire window breaker, improving the convenience of reusability of the window breaker. The mechanical window breaker has high reliability in breaking windows and will not become unusable due to power failure of other electrical components.
[0038] In one embodiment, the housing 1 is provided with a limiting seat 6 that is radially spaced apart, and the limiting seat 6 is provided with a limiting groove 61, and the trigger 3 moves against the limiting groove 61.
[0039] The housing 1 can be a cylindrical structure with a through hole 11 at its front end. Alternatively, a second end cap 7 can be detachably connected to the front end of the housing 1. The through hole 11 is located at the center of the second end cap 7. The inner wall of the second end cap 7 is connected to the outer wall of the housing 1 by a threaded connection, allowing for quick disassembly of the second end cap 7 to facilitate the installation of the impact member 2 and the first elastic member 4 into the housing 1. The first end cap 5 can be detachably connected to the rear end of the housing 1 or it can be integrally formed. In this embodiment, the first end cap 5 is integrally formed at the rear end of the housing 1. The first end cap 5 is arranged radially along the housing 1, and its outer surface is flat, allowing the trigger member 3 to smoothly abut against the outer surface of the first end cap 5.
[0040] There can be two limiting seats 6, located at the edge of the first end cover 5. This can be understood as the two limiting seats 6 being at opposite ends of the diameter. On the one hand, this is to avoid the impact member 2 extending out of the first end cover 5, and on the other hand, to achieve the purpose of balancing and supporting the trigger member 3. When the trigger member 3 is rotated on the limiting seat 6, the trigger member 3 can slide out of the limiting groove 61, releasing the restriction on the impact member 2.
[0041] In one embodiment, the impact member 2 includes a tip 21, an impact portion 22, and an impact rod 23 connected in sequence; the tip 21 extends movably through a through hole 11, the impact rod 23 extends out of the first end cap 5 and is connected to the trigger member 3, and the trigger member 3 moves radially against the first end cap 5.
[0042] The diameter of the impact part 22 is larger than the diameter of the impact rod 23. The tip 21 is located at the center of the impact part 22. The impact member 2 is arranged along the axial direction of the housing 1, and the axis of the impact member 2 coincides with the axis of the housing 1. The outer wall of the impact part 22 is slidably fitted with the inner wall of the housing 1. The impact part 22 can slide smoothly in the housing 1, thereby driving the tip 21 to extend and retract in the through hole 11.
[0043] One end of the first elastic member 4 abuts against the first end cap 5, and the other end of the first elastic member 4 abuts against the axial end face of the impact part 22 near the first end cap 5. The first elastic member 4 is fitted onto the outer wall of the impact rod 23. When the distance between the impact part 22 and the first end cap 5 is reduced, the first elastic member 4 is compressed and thus enters an energy storage state. When the distance between the impact part 22 and the first end cap 5 is increased, the first elastic member 4 rebounds and extends, thus entering an energy release state.
[0044] The axial end face of the impact part 22 away from the first end cover 5 can move and abut against the second end cover 7. Even if the trigger 3 is disengaged from the impact 2, the second end cover 7 can effectively prevent the impact 2 from being disengaged from the housing 1, avoiding the risk of the trigger 3 falling off and causing the impact 2 to fly away, thus improving the safety performance of the window breaker and having high reliability.
[0045] In one embodiment, the end of the impact member 2 away from the through hole 11 is provided with a radially opened through hole 24 and an axially opened blind hole 25. The through hole 24 and the blind hole 25 intersect and communicate with each other. The trigger member 3 passes through the through hole 24, and a limiting component 8 is provided in the blind hole 25 to abut against the trigger member 3 and fix it in the through hole 24.
[0046] The limiting component 8 includes a second elastic member 81 and a limiting member 82. The outer wall of the trigger member 3 is provided with a slot 31. One end of the limiting member 82 abuts against the slot 31, and the other end of the limiting member 82 abuts against the bottom of the blind hole 25 through the second elastic member 81.
[0047] The through hole 24 can be a circular channel, and the trigger 3 is adapted to and passes through the through hole 24. The trigger 3 can be a cylindrical structure. The slot 31 is located in the middle of the trigger 3. When the limiting member 82 abuts against the slot 31, the trigger 3 is in a fixed state that cannot rotate. The second elastic member 81 elastically acts on the limiting member 82 to press the trigger 3 tightly against the hole wall of the through hole 24. At the same time, the distances of the trigger 3 extending from both ends of the through hole 24 of the impact member 2 are equal. The trigger 3 is in a balanced position. When the trigger 3 needs to apply a pulling force, it can smoothly drive the impact member 2 to move. The stability and convenience of operation are both good.
[0048] In this embodiment, the limiting member 82 is a sphere, and the groove of the slot 31 is tangent to the spherical surface of the sphere to form a limit, so that the trigger member 3 will not easily detach from the through hole 24. The installation method of the trigger member 3 and the limiting component 8 is simple, which improves the assembly efficiency of the impact member 2 and the trigger member 3.
[0049] In one embodiment, the outer wall of the housing 1 is provided with a mounting base 9, which is mounted on the door panel of the vehicle door.
[0050] The mounting base 9 can be detachably connected to the housing 1 or integrally formed with the housing 1. The axis of the mounting base 9 is perpendicular to that of the housing 1. The mounting base 9 is provided with several mounting holes 91. The mounting base 9 is fixed to the door panel of the vehicle door by mounting parts that cooperate with the mounting holes 91. The mounting parts can be screws or bolts. A certain distance is reserved between the mounting position of the mounting base 9 on the door panel and the window glass, so that when the window breaker is not in use, that is, when the trigger 3 is against the limit seat 6, there is a gap between the tip 21 of the impact member 2 and the window glass; when the window breaker is used, after the trigger 3 is disengaged from the limit seat 6, the tip 21 of the impact member 2 interferes with the window glass, so as to achieve the purpose of breaking the window glass.
[0051] In one embodiment, a vehicle door assembly is provided, including the window breaker and the vehicle door as described in the above embodiments. The vehicle door includes a door panel and a window glass. The window breaker is mounted on the door panel, and the impact member 2 of the window breaker extends movably to the window glass and strikes and breaks the window glass.
[0052] In one embodiment, a vehicle is provided, including the window breaker or door assembly described in the above embodiments. The vehicle possesses the advantages of the window breaker described in the above embodiments, which will not be elaborated further here.
