DETAILED DESCRIPTION

[0025] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0026] The automatic battery replacement device of the robot includes a robot positioning device, a battery removal device and a battery loading device, and also includes an automatic disassembly and assembly device of the battery compartment door. The present invention mainly introduces the automatic disassembly and assembly device of the battery compartment door, which is the core invention point of the present invention, and other functions will not be repeated.

[0027] like Figure 1 and Figure 2As shown, the automatic disassembly and assembly device of the battery compartment door includes an automatic locking structure of the battery compartment door, the suction cup 4 is fixedly mounted on the suction cup frame 5, the suction cup frame 5 is fixedly mounted on the lifting frame 6, and the lifting frame 6 is fixedly mounted on the mobile base 7.

[0028] Specifically, the electric telescopic rod of the lifting frame 6 may also be any other device in the prior art that can realize the up and down lifting function.

[0029] Specifically, the mobile base 7 moves linearly along the disassembly and assembly direction of the battery compartment door 2. In particular, a linear guide rail is arranged below the mobile base 7, and wheels and a wheel driving device are arranged on the mobile base 7. Under the action of the wheel driving device, the wheels of the mobile base 7 move linearly along the linear guide rail; the wheel driving device is driven by a motor.

[0030] like Figure 3 , Figure 4 and Figure 5 As shown, the automatic locking structure of the battery compartment door, a lock hole 101 is set on the battery holder 1, and the battery compartment door 2 is locked and released on the battery holder 1 through the cooperation of the locking rod 9 and the lock hole 101. A locking valve 8 is installed on the battery compartment door 2, and the locking valve 8 is sealingly installed in the battery compartment door 2. A vent hole 3 801 and a vent hole 4 802 are set in the middle of the locking valve 8. The vent hole 3 801 and the vent hole 4 802 are communicated. The inner end of the locking valve 8 is threaded. A nut 12 is connected, a spring 11 is arranged between the nut 12 and the locking valve 8, a vent hole 201 is arranged on the battery compartment door 2, a locking rod 9 is arranged at the outer end of the vent hole 201, and a spring 10 is arranged between the locking rod 9 and the vent hole 201; it also includes a suction cup 4, the suction cup 4 includes a disc body 401 and a stopper 402, and a vent hole 403 is arranged on the side of the stopper 402, and the vent hole 403 is connected to the negative pressure source inlet 404;

[0031] When the suction cup 4 is not connected to the negative pressure source, the head of the locking rod 9 is stuck in the locking hole 101 under the action of the spring 10, so that the battery compartment door 2 and the battery holder 1 are locked. When the suction cup 4 is attached to the outer side of the battery compartment door 2 and the negative pressure source is connected, the locking valve 8 moves outward under the action of the negative pressure until the locking valve 8 presses against the block 402. At this time, the vent three 801 is on the outside of the battery compartment door 2, and the vent four 802 is connected to the vent one 201. The locking rod 9 compresses the spring 10 under the action of the negative pressure, so that the head of the locking rod 9 leaves the locking hole 101, so that the battery compartment door 2 and the battery holder 1 are loosened.

[0032] As can be seen from the figure, there are two locking holes 101 at the upper and lower positions.

[0033] As a high-tech product, the appearance of a robot is particularly important, so the battery compartment door generally needs to be made into a smooth and bright surface. Although in this patent, a hole needs to be opened on the battery compartment door 2 when installing the locking valve 8, under normal circumstances, the hole is blocked by the locking valve 8, and the outer surface of the locking valve 8 is in the same plane as the outer surface of the battery compartment door 2, which will not cause the appearance of the battery compartment door 2 to be incomplete.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
