Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-9 , the present invention discloses a toy wave gear meshing structure, including a main body housing 1, a toy transmission mechanism 8 is arranged inside the main body housing 1, and the toy transmission mechanism 8 includes a wave gear one 87 and a motor 81 for driving the wave gear one 87 to swing.

[0027] A connection groove 4 is arranged on one side of the main body housing 1, a swing rod 9 is movably arranged inside the connection groove 4, a wave gear two 91 meshing with the wave gear one 87 is arranged at one end of the swing rod 9, a spring 7 is arranged on the side of the wave gear two 91 away from the wave gear one 87, and an avoidance space 5 is arranged between one side of the inner wall of the connection groove 4 and the side of the wave gear two 91 away from the wave gear one 87. The avoidance space 5 is used when the swing rod 9 bears a large load.

[0028] Specifically, a storage groove 6 is arranged on one side of the inner wall of the connection groove 4 where the avoidance space 5 is located, and one end of the spring 7 away from the wave gear two 91 extends into the storage groove 6.

[0029] Specifically, the toy transmission mechanism 8 includes a motor 81, an eccentric gear 82, a swing gear 83, a rocker gear 84 and a transmission gear 86. The output end of the motor 81 is provided with a driving gear 85 which is transmission-connected to the eccentric gear 82 through the transmission gear 86. The cam on one side of the eccentric gear 82 extends to the inside of the rocker gear 83. The rocker gear 83 is meshed with the rocker gear 84. The wave gear 87 is provided on one side of the rocker gear 84. The toy transmission mechanism 8 is a reciprocating rocker mechanism. The rocker gear 83 is eccentrically rotated and arranged inside the main shell 1, and the starting motor 81 drives the eccentric gear 82 to rotate, and the cam on one side of the eccentric gear 82 drives the swing gear 83 to swing back and forth, and the swing gear 83 drives the rocker gear 84 to swing back and forth, and the rocker gear 84 drives the rocker rod 9 to swing back and forth through the wave gear 1 87 and the wave gear 2 91. The wave gear 1 87 can not only be used in reciprocating swing mechanisms, but other forms of motion mechanisms can also use the wave gear 1 87 and the wave gear 2 91 in combination to achieve the anti-fracture function.

[0030] Specifically, an upper cover 2 and a bottom cover 3 are respectively disposed on the top and bottom of the main housing 1 .

[0031] Specifically, the top and bottom of the main shell 1 are respectively provided with protrusions 11 at one end of which are inserted into the upper cover 2 and the bottom cover 3. The inside of the main shell 1 is also provided with a control board 12 and a battery 13 located on one side of the control board 12. The control board 12 is integrated with a charging interface and a switch. The bottom cover 3 is provided with a through hole for exposing the charging interface and the switch, which facilitates the user to operate the charging interface and the switch.

[0032] When in use, the shape and arrangement of the wave gears on the swing gear 83 and the swing rod 9 are carefully designed to ensure that the power can be stably transmitted under normal circumstances. The starter motor 81 drives the swing rod gear 84 to swing back and forth. The swing rod gear 84 drives the swing rod 9 to swing back and forth through the meshing of the wave gear 1 87 and the wave gear 2 91. Figure 8 , the spring 7 continuously applies rebound resistance to the swing rod 9, thereby ensuring the meshing stability of the wave gear 2 91 and the wave gear 1 87; when the load on the swing rod 9 is too large, refer to Figure 9 , the wave gear 2 will compress the spring 7 and retreat into the avoidance space 5, so that the wave gear 2 91 is disengaged from the wave gear 1 87; this design can effectively prevent the swing rod 9 from breaking when the load is too large. Once the load is reduced or disappears, the swing rod 9 will be reset under the action of the spring 7, so that the wave gear 2 91 is re-engaged with the wave gear 1 87, thereby restoring normal reciprocating motion.

[0033] In summary, for the meshing structure of the wave teeth of the toy, when the load on the swing rod 9 is too large, the wave teeth two will compress the spring 7 and retreat into the avoidance space 5, so that the wave gear two 91 is disengaged from the wave gear one 87. This design can effectively prevent the swing rod 9 from breaking when the load is too large. Once the load decreases or disappears, the swing rod 9 will be reset under the action of the spring 7, and the wave gear two 91 will be re-engaged with the wave gear one 87, thus restoring the normal reciprocating motion. The structural design is concise and ingenious, meeting the economic benefits and having broad application prospects.

[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
