Description

Technical Field

[0002] Car seat belts are designed to restrain occupants during a collision and prevent them from colliding with the steering wheel, dashboard, or other components, or from being ejected from the vehicle, leading to death or injury. Car seat belts, also known as seat belts, are a type of occupant restraint. They are widely recognized as the cheapest and most effective safety device, and are mandatory in many countries.

One side of the cover 402 is hinged to the outer wall of the fixed shell 2. The upper surface of the load-bearing plate 403 contacts the lower side of the limit block 307 and the spring tube 309.

The sleeve 407 The inner wall contacts the outer wall of the insert 405, the outer wall of the envelope 407 is fixedly connected to the first conductive block 408, the inner wall of the fixed shell 2 is located on the upper side of the first conductive block 408 and is fixedly connected to the second conductive block 409, the right side of the outer wall of the first conductive block 408 is fixedly connected to the threaded sleeve 410, the inner wall of the threaded sleeve 410 is threadedly connected to the threaded rod 411, the lower end of the threaded rod 411 is rotatably connected to the inner wall of the fixed shell 2 through a bearing, the alarm mechanism 4 also includes a sounder 412, the outer wall of the sounder 412 is fixedly connected to the left side of the outer wall of the fixed shell 2, the interior of the insert 405 is filled with liquid, and when the interior of the insert 405 is filled with liquid, the height to which the rod 404 can be lowered is less than the height of the tooth structure on the upper surface of the limit block 307.

[0036] The inspection mechanism 5 includes a collecting groove 501, which is an annular groove opened on the lower side of the insert tube 405. The height of the right side of the bottom of the inner wall of the collecting groove 501 is higher than the height of the left side of the bottom of the inner wall of the collecting groove 501. A connecting channel is opened on the left side of the inner wall of the collecting groove 501, and a fixed groove is opened on the left side of the outer wall of the fixed shell 2. The upper end of the connecting channel is connected to the interior of the fixed groove. A test paper 503 is fixedly connected to the inner wall of the fixed groove, and an absorbent sponge 502 is fixedly connected to the outer wall of the test paper 503. One end of the absorbent sponge 502 passes through the connecting channel and extends to the interior of the collecting groove 501.

[0037] When in use, install a power supply inside the power slot 401, electrically connect the two first conductive blocks 408 on the surface of the sleeve 407 to the power supply through wires, and electrically connect the two second conductive blocks 409 on the inner wall of the fixed shell 2 to the sounder 412 through wires, ensuring that a complete path can be formed when the first conductive block 408 contacts the second conductive block 409. Then, the connecting plate 1 is securely connected to the vehicle body. When the seat belt lock is inserted, the lock will squeeze the limit block 307 to the left, and then the lock continues to drop. The hole on the lock will cause the limit block 307 to rebound and be inserted, and the right side of the limit block 307 is limited by the stabilizing block 308, and the left side of the limit block 307 is limited by the fixing plate 303 and the load-bearing plate 403, so that it cannot be loosened. When the safety belt needs to be unfastened, the pressing block 301 is pressed downward, and the pressing block 301 moves downward to squeeze the first spring 302 to contract, and the connecting belt 312 is relaxed at the same time. As the connecting belt 312 is relaxed, the clockwork spring at the connection between the rotating pile 305 and the connecting block 304 rebounds and drives the rotating pile 305 and the rotating rod 311 to rotate and rewind the connecting belt 312. At the same time, the rotating pile 305 drives the gear 306 to rotate, so that the limiting block 307 moves left to pull out the eyelet on the lock head. At the same time, the second spring 310 contracts and deforms. After the pressing block 301 is released, the limiting block 307 returns to its original position under the elastic force of the second spring 310, and the pressing block 301 returns to its original position under the elastic force of the first spring 302.

[0038] After the vehicle overturns, the upside-down sleeve 407 of the fixed shell 2 slides to the side close to the load-bearing plate 403 due to gravity, causing the sleeve 407 to drive the threaded sleeve 410 to move. Since the threaded sleeve 410 is threadedly connected to the threaded rod 411, the threaded rod 411 will rotate to allow the threaded sleeve 410 to move. Since the threaded rod 411 rotates slowly, the sleeve 407 will not move out of the range of the drainage hole 406 at the beginning of the overturning or rolling process. Subsequently, the sleeve 407 moves out of the range of the drainage hole 406, causing the liquid in the insert 405 to flow out. At this time, the movement of the insert rod 404 loses resistance, and the second spring When the height of the fixed connection between 310 and the inner wall of the fixed shell 2 is lower than the height of the fixed connection between the second spring 310 and the outer wall of the limit block 307, the second spring 310 will drive the limit block 307 to deviate to the left side and move it away from the fixed plate 303, thereby pushing the load-bearing plate 403 and causing the toothed structure on the surface of the gear 306 to lose the meshing relationship with the toothed structure on the surface of the limit block 307. Then, the second spring 310 will rebound quickly and drive the limit block 307 to pull out the lock head. At this time, it is only necessary to pull the safety belt to make the lock head separate from the interior of the fixed shell 2, thereby achieving the purpose of quickly unfastening the safety belt and accelerating the escape speed of the personnel.

[0039] After the insert 405 slides, it drives the first conductive block 408 to move, causing the first conductive block 408 to contact the second conductive block 409. This allows the power inside the power slot 401 to form a path through the wires to the first conductive block 408, the second conductive block 409, and the sounder 412, causing the sounder 412 to emit a sharp sound, thereby attempting to wake up the driver who has lost consciousness or temporarily lost consciousness due to the overturned car, allowing the driver to quickly escape, thereby accelerating the escape speed and ensuring safety.

[0040] During daily use, if there is a bump, the movement of the cover 407 will be restricted by the connection between the threaded sleeve 410 and the threaded rod 411. The threaded connection between the threaded rod 411 and the threaded sleeve 410 will prevent the threaded rod 411 from rotating quickly when the threaded sleeve 410 rises instantly, thereby preventing the threaded sleeve 410 from rising instantly, thereby preventing the device from being accidentally touched during daily use. However, when the liquid inside the insert 405 leaks during daily use, it will flow into the inside of the collection tank 501, causing the liquid inside the collection tank 501 to wet the absorbent sponge 502, thereby causing the test paper 503 to change color, making it easy for users to observe its color to determine whether maintenance is needed, thereby achieving the purpose of sensitive triggering to ensure personnel safety when an accident occurs.

[0041] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
