DETAILED DESCRIPTION OF THE INVENTION

[0023] Reference will now be made in detail to exemplary embodiments of the invention, which are illustrated in the accompanying drawings. Hereinafter, embodiments consistent with the disclosure will be described with reference to drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. It is apparent that the described embodiments are some but not all of the embodiments of the present invention. Based on the disclosed embodiment, persons of ordinary skill in the art may derive other embodiments consistent with the present disclosure, all of which are within the scope of the present invention.

[0024] Referring to FIGS. 1-5, a safety belt structure of racing cars is disclosed. The safety belt structure includes a buckle socket 10, a buckle clip 20, and two elastic buckle locks 30. One end of the buckle socket 10 and the buckle clip 20 are mutually buckled and have a socket part 11 and a clip part 21. The other ends of the buckle socket 10 and the buckle clip 20 both have strap-through parts 12 and 22 and are respectively pivoted with transverse safety belts 121 and 221 (as shown in FIG. 9). The buckle socket 10 and the buckle clip 20 both have quick-release buckle clips 13 and 23 protruding on one side. The quick-release buckle clips 13 and 23 are provided with clip holes 131 and 231.

[0025] The elastic buckle lock 30 has a bottom case 31, an elastic plate 32, a front cover 33, and a pressure plate 34. The two sides of the bottom case 31 are symmetrically bent inwards and provided with two limiting parts 311. One end of the bottom case 31 includes a blocking part 312, and two limiting parts 311 and the blocking part 312 are not in contact to form the slot 313. The other end of the bottom case 31 is provided with a lug 314, and the lug 314 is provided with a long slot 315 for installing a shoulder safety belt 316 (as shown in FIG. 9). The elastic plate 32 has a protruding part 321 and a hollow part 322 located above the protruding part 321. The protruding part 321 has a guiding slope 323 from bottom to top. A spring piece 324 is provided at the bottom of the elastic plate 32 and is assembled in the bottom case 31. The bottom end of the elastic plate 32 is against the blocking part 312, and the other end of the spring piece 324 is away from the elastic plate 32 to form an inner support part 325. The inner support part 325 is against the inner wall of the bottom case 31 and faces the hollow part 322, so that the other end of the elastic plate 32 leans toward the two limiting parts 311. A through hole 331 is provided in the center of the front cover 33, and the pressure plate 34 is assembled on the inside of the front cover 33. The front cover 33 is assembled on the front side of the bottom case 31. The pressure plate 34 faces the elastic plate 32, and the pressure plate 34 is provided with two inner push plates 341 to support the elastic plate 32. The pressure plate 34 can be pressed through the through hole 331, so that the elastic plate 32 has an action state of pressing to unlock and rebounding the lock.

[0026] FIGS. 4-8 illustrate the various using states of the elastic buckle lock 30. When the elastic buckle lock 30 is not plugged into the quick-release buckle clips 13 and 23, the spring piece 324 of the elastic plate 32 is pressed against the inner wall of the bottom case 31 with the inner support part 325, and the top end of the elastic plate 32 is tilted toward the limiting part 311 of the bottom case 31, so that the protruding part 321 of the elastic plate 32 relatively locate above the slot 313. The pressure plate 34 on the inside of the front cover 33 pushes the inner push plate 341 past the limiting part 311 and against the surface of the elastic plate 32. Accordingly, when the quick-release buckle clips 13 and 23 of the buckle socket 10 or buckle clip 20 are inserted into the elastic buckle lock 30 through the slot 313, the quick-release buckle clips 13 and 23 will gradually squeeze the elastic plate 32 along the guide slope 323. At the same time, the spring piece 324 is compressed until the clip holes 131 and 231 are opposite to the protruding part 321. At this time, the elastic plate 32 rebounds through the inner support part 325 of the spring piece 324 to lock the protruding part 321 onto the clip holes 131 and 231, and the quick-release buckle clips 13 and 23 are further inserted and fixed on the elastic buckle lock 30 to achieve the lock between the quick-release buckle clips 13 and 23 and the elastic buckle lock 30. On the contrary, when the user wants to release the quick-release buckle clips 13 and 23 from the locked state of the elastic buckle lock 30, the user can press the pressure plate 34 through the through hole 331 of the front cover 33, so that the pressure plate 34 moves inward and use the two inner push plates 341 to push the elastic plate 32 inward, so that the protruding part 321 is separated from the clip holes 131 and 231 of the quick-release buckle clips 13 and 23. At this time, the quick-release buckle clips 13 and 23 can be pulled out or naturally hang down using their own weight, so as to achieve the effect of quick release of the quick-release buckle clips 13 and 23.

[0027] Following the above, please continue to refer FIGS. 9-10 together with FIGS. 6-8. The elastic buckle lock 30 is installed with a shoulder safety belt 316 through the long slot 315 of the lug 314. The elastic buckle lock 30 is inserted and combined and the quick-release buckle clips 13 and 23 of the buckle socket 10 the buckle clip 20 through the slot 313. The socket part of the buckle socket 10 and the clip part 21 of the buckle clip 20 are buckled and fixed to complete the buckle fastening state of at least the four-point safety belt.

[0028] Based on this, when the user wants to release the seat belt, after the buckle socket 10 is released from the buckle clip 20, the elastic buckle locks 30 can be quickly released from the buckled state by pressing the elastic buckle locks 30. The reaction force generated by the fastened state causes the elastic buckle locks 30 to jump upward and release the quick-release buckle clips 13 and 23 of the buckle socket 10 and the buckle clip 20, so as to achieve the purpose of quickly releasing the safety belt. The invention can help to gain time to escape after an accident, avoid the regret of being unable to escape immediately due to an emergency, and greatly improve the safety of seat belt use.

[0029] Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the claims.
