Technical Field
[0001] This utility model relates to the field of vehicle window technology, and in particular to an emergency escape protective window for vehicles. Background Technology
[0002] In public transportation vehicles such as buses, windows, as an important component of the vehicle body, not only serve the functions of visibility and ventilation but also play a crucial role in escape during emergencies. Especially in the event of fire, accidents, or other emergencies, windows are often the main escape routes for passengers. Therefore, to ensure passenger safety, windows need to be designed to break quickly in emergencies. Currently, most vehicle emergency escape devices on the market rely on hand-held hammers to break the windows, requiring users to manually strike the window with the hammer to shatter the glass.
[0003] Traditional handheld hammers are often difficult to use in confined spaces (such as cramped environments caused by a chaotic situation inside a vehicle), due to insufficient space and inconvenient swinging, which further affects the efficiency of breaking windows. In addition, traditional hammer designs lack fixed striking points and usually rely on markings or prompts. Users need to observe and accurately aim at the striking point to make an effective strike, which increases the difficulty of operation and the risk of error. Therefore, those skilled in the art have provided an emergency escape protection window for vehicles to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an emergency escape window for vehicles. By incorporating a window-breaking component, users can easily break the window by simply removing the isolation block and striking the pressing block, causing the tip of the hammer to hit the predetermined striking point. Compared to traditional handheld hammers, this reduces the possibility of human error, avoids difficulties caused by space constraints or improper operation, and significantly improves the accuracy and efficiency of window breaking.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an emergency escape protective window for vehicles, comprising a frame and a window glass, wherein a window breaking component is provided between the frame and the window glass, and a mounting bracket is fixedly connected to one side inner wall of the frame by multiple fixing screws;
[0006] The window-breaking assembly includes a fixing frame, a first movable groove at the front end of the fixing frame, and a second movable groove at the rear end of the fixing frame. A pressing block is movably disposed inside the first movable groove, and a striking hammer is movably disposed inside the second movable groove. A first rebound groove is disposed on one side of the inner wall of the second movable groove, and a second rebound groove is disposed inside the fixing frame near the first rebound groove. A connecting rod is movably disposed inside both the first and second rebound grooves. An isolation block is slidably disposed inside the first rebound groove, and a limit block is slidably disposed inside the second rebound groove. A return spring is movably sleeved on the outer wall of both connecting rods. A disassembly and assembly assembly is provided between the fixing frame and the mounting frame.
[0007] With the above technical solution, by incorporating a window-breaking component, during use, simply remove the isolation block and then strike the pressing block to allow the tip of the hammer to strike the predetermined striking point, thus easily breaking the window. Compared with traditional handheld hammers, this reduces the possibility of human error and avoids difficulties caused by space constraints or improper operation, significantly improving the accuracy and efficiency of window breaking. Under normal circumstances, the included return spring and isolation block can limit the hammer to a distance from the predetermined striking point, ensuring the stability and safety of the device.
[0008] Furthermore, the disassembly and assembly assembly includes a T-shaped block, which is fixedly connected to the mounting frame. The front end of the mounting frame is provided with a T-shaped groove, and the upper and lower ends of the T-shaped block are provided with reset grooves. Fixed blocks are movably arranged inside the two reset grooves. Fixed slots are provided at the upper and lower ends of the mounting frame. Multiple reset springs are fixedly connected between the two fixed blocks and the inner wall of the opposite end of the corresponding reset groove.
[0009] Through the above technical solution, by providing a disassembly and assembly component, the movement of the fixing block can be controlled to disengage it from or engage it with the fixing slot, thereby releasing the fixing restriction between the fixing frame and the mounting frame or realizing the connection and fixation between the fixing frame and the mounting frame. This enables quick disassembly and assembly of the window breaking component, facilitating the disassembly, maintenance and replacement of the window breaking component, and ensuring that the device maintains a good working condition for a long time.
[0010] Furthermore, the first movable groove and the second movable groove are connected through each other, the hammer is fixedly connected to the pressing block, and movable springs are fixedly connected to both sides of the inner wall of the pressing block and the opposite end of the first movable groove.
[0011] Through the above technical solution, by connecting the first movable groove and the second movable groove, and fixing the hammer to the pressing block, the hammer can be moved when the pressing block is hit. And by providing a movable spring, if the window glass is not fully broken by a single hit, the pressing block can be reset with the hammer so that it can be hit again.
[0012] Furthermore, the T-shaped block is engaged in the T-shaped groove, and both fixing blocks are engaged in the corresponding fixing grooves;
[0013] The above technical solution involves engaging the T-shaped block within the T-slot and engaging the fixing block within the corresponding fixing slot, thereby connecting and fixing the mounting bracket together.
[0014] Furthermore, the two ends of one of the return springs are respectively fixedly connected to the inner wall of the opposite side of the first return groove and the isolation block, and the two ends of the other return spring are respectively fixedly connected to the inner wall of the opposite side of the second return groove and the limiting block.
[0015] By using the above technical solution, the return spring can be effectively restricted, thereby confining the isolation block within the second movable groove, thus effectively isolating the hammer.
[0016] Furthermore, the isolation block and the corresponding connecting rod are fixedly connected, the limiting block and the corresponding connecting rod are fixedly connected, and the isolation block is movably disposed in the second movable groove;
[0017] By using the above technical solution, the isolation block and the corresponding connecting rod are fixedly connected, and the isolation block is movably set in the second movable groove. Then, the isolation block can be moved away from the second movable groove by pulling the corresponding connecting rod. By fixing the limiting block and the corresponding connecting rod, the isolation block can be pulled more stably and conveniently.
[0018] Furthermore, one end of each of the two connecting rods passes through the fixing frame and is fixedly connected to a pull block;
[0019] The above technical solution incorporates a pull block, which allows operators to easily move the connecting rod by pulling the block.
[0020] This utility model has the following beneficial effects:
[0021] 1. This utility model proposes an emergency escape protective window for vehicles.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides a specific embodiment of an emergency escape protection window for vehicles, including a frame 1 and a window glass 2, a window breaking component 3 is provided between the frame 1 and the window glass 2, and a mounting bracket 18 is fixedly connected to one side of the inner wall of the frame 1 by a plurality of fixing screws 17.
[0033] The window breaking assembly 3 includes a fixing frame 4. The front end of the fixing frame 4 has a first movable groove 5, and the rear end of the fixing frame 4 has a second movable groove 6. A pressing block 7 is movably disposed inside the first movable groove 5, and a striking hammer 8 is movably disposed inside the second movable groove 6. The first and second movable grooves 5 and 6 are interconnected. The striking hammer 8 is fixedly connected to the pressing block 7. Movable springs 9 are fixedly connected to both sides of the inner wall of the pressing block 7 and the first movable groove 5 at opposite ends. By connecting the first and second movable grooves 5 and fixing the striking hammer 8 to the pressing block 7, when the pressing block 7 is struck, the striking hammer 8 can be moved. Furthermore, due to the movable springs 9, when the window glass 2 is not fully broken in a single strike, the movable springs 9 can further facilitate the movement of the striking hammer 8. Spring 9 allows the pressing block 7 to return to its original position along with the striking hammer 8, thus facilitating repeated striking. A first rebound groove 10 is formed on one side of the inner wall of the second movable groove 6. A second rebound groove 11 is formed inside the fixing frame 4 near the first rebound groove 10. Connecting rods 12 are movably mounted inside both the first and second rebound grooves 10 and 11. An isolation block 13 is slidably mounted inside the first rebound groove 10, and a limit block 14 is slidably mounted inside the second rebound groove 11. Return springs 15 are movably fitted onto the outer walls of both connecting rods 12. The two ends of one return spring 15 are fixedly connected to the inner walls of the first rebound groove 10 and the isolation block 13 on opposite sides, respectively. The two ends of the other return spring 15 are fixedly connected to the second rebound groove 11 and the limit block 14 on opposite sides, respectively. On the inner wall opposite to the 4, the return spring 15 is effectively restricted, thereby restricting the isolation block 13 within the second movable groove 6, thus effectively isolating the hammer 8. The isolation block 13 is fixedly connected to the corresponding connecting rod 12, and the limiting block 14 is fixedly connected to the corresponding connecting rod 12. The isolation block 13 is movably disposed within the second movable groove 6. By fixing the isolation block 13 and the corresponding connecting rod 12 and movably disposing the isolation block 13 within the second movable groove 6, the isolation block 13 can be moved away from the second movable groove 6 by pulling the corresponding connecting rod 12. By fixing the limiting block 14 and the corresponding connecting rod 12, the isolation block 13 can be pulled more stably and conveniently. A disassembly assembly is provided between the fixing frame 4 and the mounting frame 18. Component 19, by providing a window-breaking component 3, allows for easy window breaking by simply removing the isolation block 13 and striking the pressing block 7, causing the tip of the hammer 8 to hit the predetermined striking point. Compared to a traditional handheld hammer 8, this reduces the possibility of human error and avoids difficulties caused by space constraints or improper operation, significantly improving the accuracy and efficiency of window breaking. Under normal circumstances, the return spring 15 and isolation block 13 can limit the hammer 8 to a distance from the predetermined striking point, ensuring the stability and safety of the device. One end of each of the two connecting rods 12 passes through the fixing frame 4 and is fixedly connected to a pull block 16. The pull block 16 allows the operator to easily move the connecting rods 12 by pulling the pull block 16.
[0034] Reference Figure 2 , Figure 5 and Figure 6 The assembly / disassembly component 19 includes a T-shaped block 20, which is fixedly connected to the mounting bracket 4. A T-shaped groove 21 is provided at the front end of the mounting bracket 18. Reset grooves 22 are provided at both the upper and lower ends of the T-shaped block 20. Fixing blocks 23 are movably disposed inside each of the two reset grooves 22. Fixing slots 24 are provided at both the upper and lower ends of the mounting bracket 18. The T-shaped block 20 is engaged within the T-shaped groove 21, and the two fixing blocks 23 are engaged within their respective fixing slots 24. By engaging the T-shaped block 20 within the T-shaped groove 21 and engaging the fixing blocks 23 within their respective fixing slots 24, the assembly / disassembly component can be assembled / disassembled. The fixing frame 4 is connected and fixed together with the mounting frame 18. Multiple return springs 25 are fixedly connected between the inner walls of the two fixing blocks 23 and the corresponding reset slots 22 at opposite ends. With the installation and removal assembly 19, the fixing blocks 23 can be moved by controlling them to disengage from or engage with the fixing slots 24. This releases the fixing restriction between the fixing frame 4 and the mounting frame 18 or achieves the connection and fixation between the fixing frame 4 and the mounting frame 18, enabling quick disassembly and assembly of the window breaking assembly 3. This facilitates the disassembly, maintenance and replacement of the window breaking assembly 3, ensuring that the device maintains a good working condition for a long time.
[0035] Working principle: In emergency situations, the user can pull the lever 16, which, via the connecting rod 12, retracts the isolation block 13 into the first rebound groove 10. This releases the restriction on the hammer 8, activating the window-breaking function. Then, by striking the pressing block 7, the tip of the hammer 8 strikes the predetermined point, easily breaking the window. Compared to traditional handheld hammers, this reduces the possibility of human error, avoids difficulties caused by space constraints or improper operation, and significantly improves the accuracy and efficiency of window breaking. In addition, by controlling the pressing of the fixing block 23 to disengage it from the fixing slot 24, the fixing restriction between the fixing frame 4 and the mounting frame 18 can be released, and the window breaking component 3 can be quickly removed from the mounting frame 18. During installation, simply insert the T-block 20 smoothly into the T-slot 21, and then the fixing block 23 will pop out and lock into the fixing slot 24 via the provided return spring 25 to complete the installation and fixing operation. This makes it convenient to disassemble, inspect and replace the window breaking component 3, ensuring that the device maintains a good working condition for a long time.
