The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes an automatically locking docking mechanism, including a first docking cavity 1 and a second docking cavity 2, a first buffer 3 is installed at one end of the first docking cavity 1, a second buffer 4 is installed at one end of the second docking cavity 2, a connecting groove 5 is opened inside the first docking cavity 1, and a docking structure is arranged inside the connecting groove 5.

[0020] The docking structure includes a docking rod 6, a mounting seat 7, a positioning hole 8, a positioning block 9 and a transmission structure. The mounting seat 7 is installed inside the connecting groove 5, one end of the docking rod 6 extends to the inside of the mounting seat 7, one end of the docking rod 6 is connected to one end of the second docking cavity 2, a positioning hole 8 is opened inside the docking rod 6, a positioning block 9 is arranged inside the positioning hole 8, the inner diameter of the positioning hole 8 is larger than the outer diameter of the positioning block 9, and a snap-fit ​​structure is formed between the positioning hole 8 and the positioning block 9. The transmission structure includes a fixing cavity 10, a mounting cavity 11, a servo motor The fixing chamber 10 is installed on the inner side of the two mounting seats 7, and the top and bottom of the fixing chamber 10 are both installed with mounting chambers 11. The top of the fixing chamber 10 is installed with a servo motor 12, and the top of the mounting chamber 11 is installed with a first bevel gear 13 on one side. The output end of the servo motor 12 is connected to one end of the first bevel gear 13, and the second bevel gear 14 is meshed with one side of the first bevel gear 13. A threaded rod 15 is installed at one end of the gear 14, and the threads at both ends of the threaded rod 15 are in opposite directions. The outer wall of the threaded rod 15 is symmetrically provided with a threaded sleeve 16, and the bottom end of the threaded sleeve 16 is connected to the top end of the docking rod 6. When in use, the docking rod 6 on the second docking cavity 2 is inserted into the interior of the connecting groove 5. When the docking rod 6 and the mounting seat 7 are engaged with each other, the servo motor 12 is started to drive the first bevel gear 13 to rotate. Since the first bevel gear 13 and the second bevel gear 14 are engaged with each other, the second bevel gear 14 is used to drive the threaded rod 15 to rotate. Since the threads at both ends of the threaded rod 15 are in opposite directions, the two threaded sleeves 16 are driven to move, and then under the limit of the limit rod 17 and the limit sleeve 18, the threaded sleeve 16 is used to drive the positioning block 9 to move, and the positioning block 9 is inserted into the interior of the positioning hole 8 to lock the position of the docking rod 6, thereby completing the docking of the first docking cavity 1 and the second docking cavity 2. The first docking cavity 1 and the second docking cavity 2 can be automatically locked, making the first docking cavity 1 and the second docking cavity 2 more convenient and quick when docking, thereby greatly improving the convenience of the mechanism when in use.

[0021] The limiting structure includes a limiting rod 17 and a limiting sleeve 18. The limiting rod 17 is installed inside the installation cavity 11 below. The limiting sleeve 18 is symmetrically arranged on the outer wall of the limiting rod 17. The top end of the limiting sleeve 18 is connected to the bottom end of the positioning block 9. The cross-section of the limiting rod 17 is smaller than the cross-section of the limiting sleeve 18. The limiting rod 17 and the limiting sleeve 18 form a snap-fit ​​structure. When in use, the limiting rod 17 and the limiting sleeve 18 cooperate with each other to limit the positioning block 9 when it moves, so that the positioning block 9 is more stable when it moves.

[0022] The first buffer 3 and the second buffer 4 are both annular in design, and the first buffer 3 and the second buffer 4 are adapted to each other. When in use, with the cooperation of the first buffer 3 and the second buffer 4, the first docking cavity 1 and the second docking cavity 2 can be buffered during docking, so that the first docking cavity 1 and the second docking cavity 2 have a better effect during docking, thereby greatly improving the practicability of the mechanism when in use.

[0023] Working principle: When the first docking cavity 1 and the second docking cavity 2 are docked, the docking rod 6 on the second docking cavity 2 is inserted into the interior of the connecting groove 5. With the cooperation of the first buffer 3 and the second buffer 4, the first docking cavity 1 and the second docking cavity 2 can be buffered during docking. After the docking rod 6 and the mounting seat 7 are engaged with each other, the servo motor 12 is started to drive the first bevel gear 13 to rotate. Since the first bevel gear 13 and the second bevel gear 14 are engaged with each other, the second bevel gear 14 is used to drive the threaded rod 15 to rotate. Since the threads at both ends of the threaded rod 15 are in opposite directions, the two threaded sleeves 16 are driven to move. Then, under the limit of the limit rod 17 and the limit sleeve 18, the threaded sleeve 16 is used to drive the positioning block 9 to move, and the positioning block 9 is inserted into the interior of the positioning hole 8 to lock the position of the docking rod 6, thereby completing the docking of the first docking cavity 1 and the second docking cavity 2.
