[0002] Safe escape during vehicle accidents is a crucial aspect of automotive safety. In various vehicle-related incidents such as submersion in water, traffic accidents, and fires, the ability of occupants to escape the dangerous environment in a timely manner directly impacts their safety. If escape through broken windows cannot be achieved quickly, occupants may miss the golden opportunity for escape, leading to serious injuries or fatalities—tragedies that are all too common. Therefore, developing a safe, reliable, and easy-to-use escape tool is of paramount importance for ensuring the safety of vehicle occupants.

[0003] A Chinese utility model patent with publication number CN222075738U discloses a multi-purpose window breaker, specifically a seatbelt buckle, a striking pin tip, and a window breaker hammer. One end of the seatbelt buckle is fixedly connected to the striking pin tip, and the other end is fixedly connected to the window breaker hammer. However, in this technical solution, when fastening or unfastening the seatbelt, the buckle needs to be pulled frequently. Since the striking pin tip has no protective measures and is located at one end of the buckle, during pulling, the person's hands, other body parts, or clothing can easily come into contact with the striking pin tip, potentially scratching the skin and causing bleeding, pain, etc. Utility Model Content

[0004] Therefore, in order to solve the problem that existing seat belt buckles with window-breaking functions may scratch the skin, causing bleeding and pain when pulled, the purpose of this utility model is to provide a seat belt window-breaking extension buckle, the specific technical solution of which is as follows:

[0005] A seatbelt window-breaking extension buckle includes a locking plate, a mounting structure, and a window-breaking assembly. One end of the mounting structure has a through hole, one end of the locking plate is disposed within the mounting structure and fixedly connected to the mounting structure, and the end of the locking plate away from the mounting structure passes through the through hole. The window-breaking assembly includes a window-breaking block and a transparent cover. A receiving tube is fixedly disposed on the mounting structure, one end of the window-breaking block is disposed within the receiving tube and slidably connected to the receiving tube, and the end of the window-breaking block away from the receiving tube extends out of the receiving tube. The transparent cover covers the window-breaking block and is detachably connected to the mounting structure.

[0030] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0031] Example 1

[0032] like Figures 1-7 As shown, a seatbelt window-breaking extension buckle according to one embodiment of this utility model includes a locking plate 1, a mounting structure 2, and a window-breaking component 3. One end of the mounting structure 2 has a through hole 21. One end of the locking plate 1 is disposed within the mounting structure 2 and fixedly connected to it. The end of the locking plate 1 away from the mounting structure 2 passes through the through hole 21. The window-breaking component 3 includes a window-breaking block 31 and a transparent cover 32. A receiving tube 22 is fixedly disposed on the mounting structure 2. One end of the window-breaking block 31 is disposed within the receiving tube 22 and slidably connected to it. The end of the window-breaking block 31 away from the receiving tube 22 extends out of it. The transparent cover 32 covers the window-breaking block 31 and is detachably connected to the mounting structure 2. By setting the window-breaking component 3, which includes the window-breaking block 31 and the transparent cover 32, in an emergency requiring window breaking for escape, the user can quickly impact the window glass with the window-breaking block 31, thereby breaking the glass and providing an escape route for passengers. When the window-breaking function is not in use, the window-breaking block 31 is mostly located within the receiving tube 22, protected by it from collisions, scratches, or corrosion from external objects. This extends the service life of the window-breaking block 31 and ensures it can function properly when needed. The transparent cover 32 forms a physical barrier, effectively preventing the window-breaking block 31 from being affected by the external environment. It prevents dust, debris, and other contaminants from entering the receiving tube 22 and affecting the sliding performance of the window-breaking block 31; it also prevents passengers from accidentally touching the window-breaking block 31 during daily use, thus protecting their safety.

[0033] As a preferred embodiment of this utility model, it may also have the following additional technical features: the mounting structure 2 includes a front mounting plate 23 and a rear mounting plate 24, which are detachably connected. A locking piece 1 is disposed between the front mounting plate 23 and the rear mounting plate 24, and is clamped between them. The fixing action of the mounting plates ensures that the locking piece 1 will not loosen or fall off during use, thus guaranteeing the reliability of the seatbelt system. A receiving tube 22 is located on the front view of the front mounting plate 23, allowing the user to directly see the position of the window-breaking block 31 when using the window-breaking assembly 3, facilitating quick operation. Meanwhile, based on the user's usage habits when pulling the seat belt, since the receiving tube 22 is located on the front view of the front mounting plate 23, the window breaking block 31 is also located on the front view of the front mounting plate 23. Compared with the traditional window breaker located on the side of the buckle, this can effectively reduce the risk of misoperation. At the same time, when using the window breaking component 3, the user does not need to change the body posture and line of sight when pulling the seat belt to see the position of the window breaking block 31 directly, which makes it easy to quickly and directly operate the window breaking block 31 to break the window.

[0034] As a preferred embodiment of this utility model, it may also have the following additional technical features: the front mounting plate 23 has limiting holes 231 on both sides of the receiving tube 22, and the transparent cover 32 includes a cover body 321 and a limiting block 322. The limiting block 322 is fixedly connected to the cover body 321, and the limiting block 322 passes through the limiting hole 231 and is detachably connected to the front mounting plate 23. When breaking the window is not required, the limiting block 322 passes through the limiting hole 231 until the cover body 321 abuts against the front mounting plate 23, then the cover body 321 is rotated so that the limiting block 322 abuts against the inner wall of the front mounting plate 23 to achieve a fixed position; when breaking the window is required, the cover body 321 is simply rotated in the opposite direction so that the limiting block 322 can completely disengage from the limiting hole 231. The transparent cover 32 can prevent the window breaker block 31 from being hit, scratched or corroded by external objects, and avoid the window breaker block 31 from being unable to be used normally at critical moments due to damage. At the same time, it can effectively prevent people inside the vehicle from being injured due to accidental contact.

[0035] As a preferred embodiment of this utility model, it may also have the following additional technical features: the limiting block 322 includes a connector 3221 and a locking protrusion 3222. One end of the connector 3221 is fixedly connected to the cover 321, and the end of the connector 3221 away from the cover 321 is fixedly connected to the locking protrusion 3222. The design of the locking protrusion 3222 matches the limiting hole 231 on the front mounting plate 23. When the limiting block 322 passes through the limiting hole 231 and the cover 321 is rotated, the locking protrusion 3222 can tightly abut against the inner wall of the front mounting plate 23, thereby fixing the transparent cover 32 in a fixed position. This ensures that the transparent cover 32 can stably cover the receiving tube 22 when the window does not need to be broken, providing reliable protection for the window-breaking block 31.

[0036] As a preferred embodiment of this utility model, it may also have the following additional technical features: the window breaking block 31 includes a mounting base 311 and a hammer head 312. The hammer head 312 is fixedly connected to the mounting base 311, and the mounting base 311 is slidably connected to the receiving tube 22. One end of the hammer head 312 away from the mounting base 311 protrudes through the receiving tube 22. When it is necessary to break the window, since the end of the hammer head 312 away from the mounting base 311 protrudes through the receiving tube 22, it can directly act on the glass at the moment of impact, generating a large impact force, effectively improving the success rate of breaking the window. Especially in emergency situations, it can quickly break the car window, buying precious time for escape. In addition, the receiving tube 22 plays a certain protective role for the hammer head 312. When the window breaking function is not used, the hammer head 312 is located inside the receiving tube 22, avoiding the hammer head 312 from being hit, scratched, or corroded by external objects, preventing the hammer head 312 from being damaged and affecting the window breaking effect, and extending the service life of the window breaking block 31.

[0037] As a preferred embodiment of this utility model, it may also have the following additional technical features: a sliding groove 221 is provided inside the receiving tube 22, an elastic element 222 is provided inside the sliding groove 221, a sliding block 313 is provided on the outer wall of the mounting base 311, one end of the elastic element 222 is fixedly connected to the sliding groove 221, and the end of the elastic element 222 away from the sliding groove 221 is fixedly connected to the sliding block 313, which is disposed inside the sliding groove 221. When the user breaks the window by striking the glass, the hammer head 312 will move towards the elastic element 222. The elastic element 222 plays a buffering role at this time, absorbing and dispersing the impact force generated during the movement of the hammer head 312, avoiding damage to the locking plate 1 during the striking process, and ensuring the integrity and reliability of the locking plate 1. In this embodiment, the elastic element 222 is set as a spring. For ordinary users, breaking a window in an emergency may be difficult to control due to tension. The buffering effect of the spring can compensate for the instability of the user's operating force to a certain extent.

[0038] As a preferred embodiment of this utility model, it may also have the following additional technical features: the surface of the hammer head 312 is set as a frosted surface. In this embodiment, the surface of the frosted surface is provided with micro-ridges, which enhances the friction and impact force when it comes into contact with the glass, so that each strike can accurately and effectively transmit force.

[0039] As a preferred embodiment of this utility model, it may also have the following additional technical features: the end of the mounting structure 2 away from the through hole 21 is provided with a slot 25, which is perfectly matched with the standard buckle of the train seat belt. In daily use, the standard buckle of the seat belt can be firmly inserted into the slot 25, which can extend the effective length of the seat belt and provide a more comfortable riding experience for taller or fatter passengers, avoiding discomfort caused by the seat belt tightening around the body.

[0040] As a preferred embodiment of this utility model, it may also have the following additional technical features: the window breaking block 31 is made of alloy metal and undergoes a special heat treatment process to ensure that it has excellent destructive power when striking glass.

[0041] Example 2

[0042] This utility model also provides an embodiment 2, such as Figure 8 As shown, as a modified structure of Embodiment 1, Embodiment 2 differs from Embodiment 1 only in the specific structure of the aforementioned window-breaking block 31, as follows: At least seven hammers 312 are provided, and each hammer 312 is arranged in a ring, uniformly and equidistantly around the inner wall of the receiving tube 22, which significantly increases the contact area with the glass when breaking the window. The simultaneous action of multiple hammers 312 can more effectively concentrate the force and quickly shatter the car window glass. The ring-shaped arrangement of multiple hammers 312 ensures that the force is evenly distributed on the glass when breaking the window, thereby improving the success rate and efficiency of breaking the window.

[0043] The safety belt window-breaking extension buckle in this embodiment has a reasonable structural design and is easy to use. This structure can also be used for other equipment with similar usage requirements. In this embodiment, the safety belt window-breaking extension buckle effectively protects people's safety while providing a guarantee for emergency escape, thus improving the practicality and safety of the product.
