[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1 、 Figure 2 、 Figure 3 As shown, the shock-absorbing gear comprises a gear body 1 and a tooth 2. Both sides of the tooth 2 are provided with a movable plate 1 3 and a movable plate 2 4 that can be folded toward the inside of the tooth 2. The connection between the movable plate 1 3 and the movable plate 2 4 and the tooth 2 is provided with a shaft 5, and a crescent spring 6 is provided on the shaft 5.

[0016] The tooth 2 has a multi-section structure. A sliding portion 7 that can slide up and down inside the tooth 2 is provided at the upper end of the tooth 2. A sliding portion 8 is provided below the sliding portion 7. A receiving cavity 9 for receiving the sliding portion 7 is provided on the sliding portion 8. An elastic element 10 for elastic reset is provided in the receiving cavity 9. A receiving cavity 11 for receiving the sliding portion 8 is provided in the tooth 2. An elastic element 12 is provided in the receiving cavity 11.

[0017] Matching parts 13 abutting against movable plate 1 3 are provided on both sides of sliding part 1 7 , and matching parts 14 abutting against movable plate 2 4 are provided on both sides of sliding part 2 8 .

[0018] A folding bin 15 for folding the movable plate 3 is provided between the first matching portion 13 and the second matching portion 14 , and a folding bin 2 16 is provided below the second matching portion 14 .

[0019] The top ends of the movable plate 1 3 and the movable plate 2 4 are both arc-shaped.

[0020] When the gear body 1 collides, it will first contact the sliding part 17, and the sliding part 17 will slide into the storage chamber 19. At the same time, the top of the movable plate 13 will be folded inward along the bottom of the matching part 13 into the folding chamber 15. When the inner side of the movable plate 13 is completely in contact with the matching part 2 14, the matching part 13 will drive the matching part 2 14 to move downward, driving the sliding part 2 8 to slide into the storage chamber 2 11. At the same time, the top of the movable plate 2 4 will be folded along the bottom of the matching part 2 14 into the folding chamber 2 16.

[0021] After the collision is completed, the elastic original component 10 and the elastic original component 2 12 are reset, and the sliding part 1 7 and the sliding part 2 8 are pushed out of the receiving cavity 1 9 and the receiving cavity 2 11, and the movable plate 1 3 and the movable plate 2 4 are reset by the crescent spring 6.

[0022] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0023] Although this document frequently uses terms such as gear body 1, tooth 2, movable plate 1 3, movable plate 2 4, shaft 5, crescent spring 6, sliding portion 1 7, sliding portion 2 8, receiving chamber 1 9, elastic element 1 10, receiving chamber 2 11, elastic element 2 12, mating portion 1 13, mating portion 2 14, folding chamber 1 15, and folding chamber 2 16, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.
