[0036] With reference to Figure 3 , Figure 4 and Figure 5 , the inside of the shell 1 is further provided with an air cooling assembly 5, which comprises a sliding part 51 and an air cooling part 52. The sliding part 51 is used to drive the battery module 4 to slide towards or away from the central heat dissipation column 2, so that a gap is formed between the battery module 4 and the central heat dissipation column 2 when the battery module 4 is away from the central heat dissipation column 2, and the air cooling part 52 is used to deliver gaseous refrigerant (such as cold air) to the gap to help the central heat dissipation column 2 accelerate heat dissipation of the battery module 4. In addition, a control module 6 and a temperature sensor 61 are further included. The temperature sensor 61 is electrically connected to the control module 6, and the sliding part 51 and the air cooling part 52 are controlled by the control module 6. The control module 6 can be a PLC controller. The temperature sensor 61 is used to detect the temperature data of the battery module 4. When the temperature data is higher than a preset temperature threshold, the control module 6 controls the sliding part 51 and the air cooling part 52 to start, so as to form the gap and deliver gaseous refrigerant to the gap. When the temperature data is not higher than the preset temperature threshold, the control module 6 controls the sliding part 51 and the air cooling part 52 to be closed, so that the battery module 4 adheres to the side wall of the central heat dissipation column 2 to close the gap.

The outer peripheral wall of the annular cooling pipe is attached to the inner wall of the cavity 21, the hollow part of the annular cooling pipe 22 is communicated with the cavity 21, and the top of the cavity 21 is communicated with the outside of the shell 1.

[0038] The air cooling part 52 includes a plurality of fans 521 arranged along the axis of the center heat dissipation column 2, and the fans 521 are arranged one-to-one corresponding to the battery modules 4. The air inlet of the fan 521 is communicated with the hollow part of the annular cooling pipe 22, the air outlet of the fan 521 is directed to the side wall at the top of the corresponding battery module 4, and is communicated with the gap between the battery module 4 and the center heat dissipation column 2. The inside of the shell 1 and the side of each battery module 4 away from the heat dissipation framework 3 are respectively provided with a flow passage 13, the flow passage 13 is provided with a flow hole communicated with the gap at the side wall of the battery module 4, and the length direction of the flow passage 13 is parallel to the length direction of the corresponding battery module 4. The temperature sensor 61 is arranged in the flow passage 13 to take the temperature in the flow passage 13 as the temperature data representing the temperature of the battery module 4. The end of the flow passage 13 away from the center heat dissipation column 2 is provided with a through hole 131 penetrating through the shell 1, so that the flow passage 13 is communicated with the external environment of the shell 1.

[0039] Referring to Figure 3 , Figure 4 and Figure 5 , the sliding part 51 includes a motor 511, a sliding rod 512, an abutting protrusion 513 and an elastic member. The abutting protrusion 513 and the elastic member are arranged one-to-one corresponding to the battery modules 4. The elastic member is connected between the side wall of the corresponding battery module 4 and the side wall of the adjacent sector-shaped heat insulation plate 12, and the extension direction of the elastic member is parallel to the radial direction of the center heat dissipation column 2. The elastic member is a spring, which realizes the sliding of the corresponding battery module 4 relative to the shell 1. When the elastic member is not deformed, the battery module 4 is attached to the side wall of the center heat dissipation column 2, and there is no gap between the battery module 4 and the center heat dissipation column 2.

[0040] The butt joint protrusions 513 and the sliding rod 512 are connected to the bottom of the center heat dissipation column 2 through spring sliding, and the sliding direction of the butt joint protrusions 513 is parallel to the radial direction of the center heat dissipation column 2, the sliding rod 512 is connected to the center heat dissipation column 2 along the axial direction of the center heat dissipation column 2, the motor 511 is installed at the bottom of the center heat dissipation column 2, and the driving end of the motor 511 is connected with the cam 514.

When the cam 514 rotates under the driving of the motor 511, the cam 514 will touch the sliding rod 512, so that the sliding rod 512 slides towards the butt joint protrusions 513 and touches the butt joint protrusions 513, so that the ends of the butt joint protrusions 513 protrude out of the center heat dissipation column 2 and push the corresponding battery module 4, so that the battery module 4 is separated from the center heat dissipation column 2, that is, a gap is formed between the battery module 4 and the center heat dissipation column 2. When the motor 511 rotates to make the cam 514 separate from the sliding rod 512, the sliding rod 512 and the butt joint protrusions 513 will slide back under the action of the spring force, and correspondingly, the battery module 4 will also slide back under the action of the elastic force of the elastic member and recombine with the side wall of the center heat dissipation column 2.

When the torsional spring 141 is not deformed, the cover plate 142 covers the through hole 131, so that the flow-through channel 13 and the external environment of the shell 1 are not in communication, and the cover plate 142 can open the through hole 131 during the rotation of the rotating shaft 14. Specifically, the side wall of the rotating shaft 14 is also provided with an extension rod 143, and each battery module 4 is provided with a butt joint rod 42. When the torsional spring 141 is not deformed, the extension rod 143 is located on the sliding path of the butt joint rod 42 when the butt joint rod 42 slides with the battery module 4 driven by the sliding part 51, so that the butt joint rod 42 pushes the extension rod 143 during the sliding, and the extension rod 143 drives the rotating shaft 14 and the cover plate 142 to rotate, thereby opening the through hole 131.

[0042] The implementation principle of the battery module of the humanoid robot in the embodiment of the application is as follows: the temperature sensor 61 is used to monitor the temperature data of the battery module 4 in the shell 1 in real time; when the temperature data is not higher than a preset temperature threshold, the phase change material 31 in the honeycomb heat dissipation cavity and the central heat dissipation column 2 are used to cooperate to realize heat dissipation of the battery module 4; when the temperature data is higher than the preset temperature threshold, the control module 6 starts the motor 511 to drive the battery module 4 to move away from the central heat dissipation column 2, so that a gap is formed between the central heat dissipation column 2 and the battery module 4, and the through hole 131 is opened at this time; then the control module 6 starts the fan 521 to draw air from the outside of the shell 1, and the air enters the gap after being cooled by the annular cooling pipe 22, and then flows into the flow-through passage 13 after the side wall of the battery module 4 in the height direction is cooled in the process of flowing through the gap, and then flows out of the through hole 131 after the top wall of the battery module 4 is cooled under the limiting action of the flow-through passage 13, so as to use the air cooling assembly 5 to help the central heat dissipation column 2 to accelerate the heat dissipation efficiency of the battery module 4.
