[0038] In an embodiment, the first partition 18 and the second partition 20 are connected vertically, that is, the connection of the first partition 18 and the second partition 20 forms a vertical effect, so as to form a more stable support effect.

[0042] The second partition 20 is formed between the side away from the storage space 24 and the shell 12 to form a heat equalization cavity 31, that is, the second partition 20 divides the internal space of the shell 12 into the heat equalization cavity 31 and the storage space 24, and the first partition 18 further divides the storage space 24 into the heat insulation cavity 22 and the battery cavity 26. The heat generated by the charging module 14 is first diffused in the heat insulation cavity 22, part of the heat in the heat insulation cavity 22 is directly diffused outward through the part of the shell 12 corresponding to the heat insulation cavity 22, part of the heat in the heat insulation cavity 22 is diffused into the battery cavity 26 through the first partition 18, and the heat in the battery cavity 26 is diffused outward through the part of the shell 12 corresponding to the battery cavity 26.

[0044] In an embodiment, the heat equalizing cavity 31 is provided with a retractable charging wire module 32, which is mounted on the second partition 20 and electrically connected with the charging module 14. The charging wire of the retractable charging wire module 32 has a retractable function, and can be wound and stored inside the shell 12 when not in use, and can be pulled out of the shell 12 to a suitable length when in use, which is convenient for users to use. In addition, when the charging wire is pulled out of the shell 12, the charging wire can also play a role in assisting the heat equalizing cavity 31 to dissipate heat.
