[0038] In the present embodiment, the supporting mechanism 8 comprises a support rod 1 801 and a support rod 2 802. Both the support rod 1 801 and the support rod 2 802 are made of stainless steel hollow rods. The two ends of the support rod 1 801 are respectively connected to the plate 1 4 and the plate 2 5. The two ends of the support rod 2 802 are respectively slidably connected to the plate 1 4 and the plate 2 5. A sleeve 22 is provided on the outer side of the support rod 1 801.

[0039] In this solution, when it rains, the driving unit can drive the support rod 802 to slide along the annular groove of plate 2, thereby driving the protective cover wound on the sleeve 22 to unfold, thereby protecting the charging pile from rain erosion.

[0040] As an optional embodiment of the present invention, refer to Figure 5 The driving unit includes a support seat 25, a slider 29 is provided at the bottom of the support seat 25, a slide groove 28 is provided on the bottom surface of the annular groove of the plate 25 to be slidably connected to the slider 29, the top of the support seat 25 is rotatably connected to the bottom end of the support rod 202, a receiving groove (not shown) is provided on the side of the support seat 25, a driving motor 27 is installed in the receiving groove, a driving gear 26 is installed at the output end of the driving motor 27, and a gear ring meshing with the driving gear 26 is also fixed to the side wall of the annular groove of the plate 25. The driving motor can be used with an external power supply.

[0041] In this plan, specific reference is made to Figure 8The rotating unit includes a winding motor 24, which is mounted on the top of the plate 14. A mounting hole 31 is provided in the middle of the shell of the plate 14. The output shaft of the winding motor 24 is located in the mounting hole 31 and is installed with a driving gear 33. The bottom surface of the annular groove of the plate 14 is also provided with an annular slot (not shown). The slot and the mounting hole 31 are connected through at least one connecting hole (not shown). A transmission gear ring 32 is movably installed in the slot. A connecting sleeve 34 is coaxially fixed to the bottom of the transmission gear ring 32. The bottom of the connecting sleeve 34 is coaxially fixed to the top of the sleeve 22.

Through the above structure, the protective cover can be automatically unfolded or wound by the winding motor, which is more convenient to use.

[0042] A water hole 30 is provided on the side of the shell of plate 2 5 away from the pile body 14. As rainwater drops onto the outer surface of the protective cover, it flows back along the protective cover into the annular groove of plate 2 under the action of gravity.
