[0020] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Example 1: Please refer to Figure 1 - Figure 6 , an AGV unmanned driving automatic charging device of this embodiment includes a vehicle body 1 and a charging base station 2. A plurality of guide wheels 3 are arranged around the vehicle body 1. A charging slot 5 is opened at one end of the vehicle body 1. A charging plug 4 is arranged inside the charging base station 2. One end of the charging plug 4 is plug-in connected to the inside of the charging slot 5. A motor 8 is arranged on the top of the charging base station 2. One end of the motor 8 is connected to a transmission mechanism. One end of the transmission mechanism is fixedly connected to a bidirectional threaded rod 12. Two ends of the bidirectional threaded rod 12 are threadedly connected to two movable splints 13. A fixing column 6 is fixedly connected to one side of the bottom of the movable splint 13. The fixing column 6 is movably connected to the inside of the charging base station 2. Two fixing slots 7 are opened on both sides of the vehicle body 1. One end of the fixing column 6 is plug-in connected to the inside of the fixing slot 7.

[0022] Among them, when the vehicle body 1 enters the interior of the charging base station 2 for charging, the position is adjusted by the external sensing camera of the vehicle body 1, so that the vehicle body 1 moves toward the interior of the charging base station 2, and at the same time, the interior of the charging slot 5 is aligned with the charging plug 4. When the charging plug 4 is fully inserted into the interior of the charging slot 5 and charging begins, the motor 8 is started, and the motor 8 drives the transmission mechanism to move, and the transmission mechanism drives the bidirectional threaded rod 12 to rotate, and the bidirectional threaded rod 12 drives the two movable splints 13 to move. The two movable splints 13 move closer to each other and drive the fixing column 6 to move, so that the fixing column 6 is inserted into the interior of the fixing slot 7, thereby facilitating the fixing of the vehicle body 1 during charging;

[0023] Furthermore, a groove is machined on the top of the charging base station 2, and a transmission mechanism and a bidirectional threaded rod 12 are movably connected inside the groove. The transmission mechanism includes a first rotating roller 9, a synchronous belt 10, and a second rotating roller 11. One end of the motor 8 is fixedly connected to one end of the first rotating roller 9, the outside of the first rotating roller 9 is transmission-connected to one end of the synchronous belt 10, and the other end of the synchronous belt 10 is transmission-connected to the outside of the second rotating roller 11. The second rotating roller 11 is fixedly connected to the middle of the bidirectional threaded rod 12.

[0024] When the motor 8 is started, the motor 8 will drive the first rotating roller 9 to rotate, the first rotating roller 9 will drive the synchronous belt 10 to move, the synchronous belt 10 will drive the second rotating roller 11 to rotate, so that the second rotating roller 11 will drive the bidirectional threaded rod 12 to rotate;

[0025] Furthermore, two movable grooves 14 are processed on both sides of the charging base station 2, and the movable splint 13 is movably connected to the inside of the movable groove 14. The inside of the movable groove 14 is fixedly connected to the limiting rod 15, and the middle part of the movable splint 13 is movably connected to the outside of the limiting rod 15. When the bidirectional threaded rod 12 drives the movable splint 13 to move, the movable splint 13 will move along the inside of the movable groove 14. When the movable groove 14 moves, the middle part of the movable groove 14 will move along the outside of the limiting rod 15. By providing the limiting rod 15, the limiting rod 15 will limit the movement of the movable splint 13, so that the movable splint 13 remains stable during movement.

[0026] Furthermore, when the vehicle body 1 is fully charged, the motor 8 is started, which drives the fixed column 6 to move through the transmission mechanism, the bidirectional threaded rod 12, and the movable clamping plate 13, so that the fixed column 6 is separated from the interior of the fixing groove 7. Since the guide plate 201 is provided at the bottom of the charging base station 2, the vehicle body 1 will slide downward along the guide plate 201 under the action of gravity and separate from the interior of the charging base station 2, thereby timely disconnecting the power supply;

[0027] The ramps 202 are provided on both sides of the interior of the charging base station 2, so that the opening of the charging base station 2 is large and the inner opening is small. When the vehicle body 1 enters the interior of the charging base station 2, the vehicle body 1 moves closer to the ramps 202, and the guide wheels 3 come into contact with the ramps 202, thereby the ramps 202 play a guiding and correcting role for the vehicle body 1.

[0028] Working principle: When the vehicle body 1 enters the interior of the charging base station 2 for charging, the position is adjusted through the external sensing camera of the vehicle body 1, so that the vehicle body 1 moves toward the interior of the charging base station 2, and at the same time, the interior of the charging slot 5 is aligned with the charging plug 4. When the charging plug 4 is fully inserted into the interior of the charging slot 5 and charging begins, the motor 8 is started, and the motor 8 will drive the first rotating roller 9, the synchronous belt 10 and the second rotating roller 11 to rotate. The second rotating roller 11 will drive the bidirectional threaded rod 12 to rotate, and the bidirectional threaded rod 12 will drive the two movable splints 13 to move. The two movable splints 13 approach each other and drive the fixed column 6 to be inserted into the interior of the fixed slot 7, thereby facilitating the fixation of the vehicle body 1 during charging.

[0029] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
