In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0036] like Figure 1-Figure 5 As shown, the present embodiment provides a waterproof structure of a charging pile, including a shell assembly 1, the shell assembly 1 having a accommodating cavity and a drainage hole 14 located at the bottom end of the shell assembly 1, the shell assembly 1 comprising a bottom shell 16 and a surface cover component 17, the surface cover component 17 is arranged on the bottom shell 16 to enclose with the bottom shell 16 to form an accommodating cavity, the accommodating cavity comprises a main accommodating cavity 13 and an auxiliary accommodating cavity 12; the main accommodating cavity 13 is used to accommodate a non-waterproof component 3, and the auxiliary accommodating cavity 12 is used to accommodate a self-waterproof component 2; the shell assembly 1 has a waterproof portion, at least a portion of the waterproof portion is arranged around the circumference of the main accommodating cavity 13, and the peripheral side of the main accommodating cavity 13 forms a drainage channel extending to the drainage hole 14. Among them, the self-waterproof component 2 is arranged in the auxiliary accommodating chamber 12, and the non-waterproof component 3 is arranged in the main accommodating chamber 13. As long as the main accommodating chamber 13 meets the waterproof requirements, the waterproof part is arranged around the circumference of the main accommodating chamber 13, and the waterproof part around the main accommodating chamber 13 realizes the waterproof function of the main accommodating chamber 13, which minimizes the size of the main accommodating chamber 13 and reduces the sealing cost; and compared with the overall sealing, the auxiliary accommodating chamber 12 does not need to be sealed, and the size of the main accommodating chamber 13 that needs to be sealed is smaller, which reduces the difficulty of sealing, reduces the probability of sealing failure, and improves waterproof reliability. Furthermore, when rainwater enters the auxiliary accommodating chamber 12, the water in the auxiliary accommodating chamber 12 can be discharged in turn through the drainage channel and the drainage hole 14 at the bottom of the shell assembly 1 by gravity, and will not be deposited in the auxiliary accommodating chamber 12. Of course, in other embodiments, the waterproof part can also be arranged around the circumference of the auxiliary accommodating chamber 12, so that the auxiliary accommodating chamber 12 also has a waterproof function.

Under the impact of the water flow, part of the water flows into the second drainage channel 15, and the other part of the water still flows into the first drainage channel 11. Finally, the water in the second drainage channel 15 and the first drainage channel 11 flows out through the drainage hole 14 at the bottom of the shell assembly 1. When the first drainage channel 11 is blocked, the water in the auxiliary accommodation chamber 12 flows out through the second drainage channel 15 and the drainage hole 14, thereby improving the reliability of drainage.

[0038] Furthermore, a plurality of water guide holes 1712 are provided between the first drainage channel 11 and the second drainage channel 15.

[0040] Preferably, the end of the through hole 162 close to the main accommodating chamber 13 is higher than the end of the through hole 162 close to the auxiliary accommodating chamber 12. In this embodiment, the through hole 162 is inclined relative to the gravity direction, and the through hole 162 gradually decreases from the end close to the main accommodating chamber 13 to the end away from the main accommodating chamber 13, so as to prevent the water flow in the auxiliary accommodating chamber 12 from entering the main accommodating chamber 13 through the through hole 162 due to gravity, causing water seepage.
