[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Reference Figures 1-5 As shown, this utility model discloses a charging base with a drainage structure, comprising:

[0029] A charging housing 1 has a mechanical locking groove 11, a first connection port 12, and a second connection port 13 on its surface. The first connection port 12 and the second connection port 13 penetrate the charging housing 1. The mechanical locking groove 11 is located on one side of the first connection port 12 and the second connection port 13. A first drainage hole 111 and a second drainage hole 112 are formed on the side wall of the mechanical locking groove 11. The first drainage hole 111 communicates with the first connection port 12, and the second drainage hole 112 communicates with the second connection port 13. A plurality of drainage channels 113 are provided on the end face of the mechanical locking groove 11, and the ports of the drainage channels 113 are located on the side close to the first connection port 12 and the second connection port 13.

[0030] A DC charging module 2, wherein the input end of the DC charging module 2 passes through the first connection port 12, and a third drainage hole 21 is provided on the surface of the DC charging module 2;

[0031] An AC charging module 3 is provided, with its input end passing through the second connection port 13, and a fourth drain hole 31 provided on its surface.

[0032] In this invention, the charging housing 1 serves as a supporting structure, internally housing a DC charging module 2 and an AC charging module 3 for connecting different charging guns and enabling switching between different charging modes. The mechanical locking groove 11 on the surface of the charging housing 1 engages with the mechanical locking structure of the charging gun to secure it.

[0033] Specifically, the connection between the charging housing 1 and the vehicle body sheet metal is such that, during actual installation, the mechanical locking groove 11 is positioned above the first connection port 12 and the second connection port 13. A first drain hole 111 is located above the first connection port 12, and a second drain hole 112 is located above the second connection port 13. When water accumulates in the mechanical locking groove 11, it can be drained into the first connection port 12 and the second connection port 13 through the first drain hole 111 and the second drain hole 112, respectively. A third drain hole 21 is provided on the surface of the DC charging module 2 inside the first connection port 12 to drain the accumulated water; similarly, a fourth drain hole 31 is provided on the surface of the AC charging module 3 inside the second connection port 13 to drain the water from the second connection port 13.

[0034] Secondly, due to the irregular shape of the vehicle's sheet metal structure, the charging socket cannot be installed perpendicular to the ground during actual installation. When the charging housing 1 is installed at an angle, water will accumulate at the corners of the side walls and end faces of the mechanical lock groove 11. Specifically, multiple drainage channels 113 are provided on the end face of the mechanical lock groove 11. The drainage channels 113 penetrate the charging housing 1 and can drain the remaining water in the mechanical lock groove 11.

[0035] This invention can drain the water inside the mechanical lock groove 11 through the drainage hole and drainage channel, preventing water from accumulating inside the mechanical lock groove 11 and causing it to freeze during car washing in winter, thus ensuring that the mechanical lock can be locked normally and the vehicle can be charged normally.

[0036] Furthermore, metal support members 114 are embedded inside both the first drainage hole 111 and the second drainage hole 112.

[0037] Specifically, the charging shell 1 in this utility model is an injection molded part. The wall thickness between the mechanical locking groove 11 and the first connection port 12 and the second connection port 13 is relatively thin. After opening the first drainage hole 111 and the second drainage hole 112 in between, it is easy to damage the structural strength between the mechanical locking groove 11 and the first connection port 12 and the second connection port 13. By adding metal support members 114 in the first drainage hole 111 and the second drainage hole 112, the structural strength of the first drainage hole 111 and the second drainage hole 112 can be guaranteed and the service life can be extended.

[0038] Furthermore, the third drain hole 21 and the fourth drain hole 31 are respectively provided with a first drain nozzle 22 and a second drain nozzle 32. Specifically, after the accumulated water is drained into the first connection port 12 and the second connection port 13, it can flow from the third drain hole 21 and the fourth drain hole 31 into the first drain nozzle 22 and the second drain nozzle 32, respectively.

[0039] Furthermore, it also includes a manifold 4, to which both the first drain nozzle 22 and the second drain nozzle 32 are connected.

[0040] Specifically, the water accumulated at the first drain nozzle 22 and the second drain nozzle 32 is collected together through the manifold 4 and then drained away from the other end of the manifold 4.

[0041] Furthermore, both the DC charging module 2 and the AC charging module 3 are connected to the charging housing 1 via bolts 14. A plurality of connecting rods 15 are provided on the side of the charging housing 1 away from the mechanical locking groove 11, and each connecting rod 15 has a threaded hole 16 that mates with the bolts 14.

[0042] Specifically, in the actual assembly process, the DC charging module 2 and the AC charging module 3 are installed from the side of the charging housing 1 away from the mechanical locking groove 11, and are connected and fixed to the charging housing 1 by bolts 14. Similarly, the connecting rod 15 is integrally molded with the charging housing 1 by injection molding.

[0043] Furthermore, a buckle 17 is provided on the surface of the charging housing 1 near the mechanical lock groove 11.

[0044] Specifically, during the actual assembly process, the charging housing 1 is connected to the sheet metal parts of the car. The beveled surface of the buckle 17 facilitates the pressing of the charging housing 1 into the mounting opening of the sheet metal. As a preferred embodiment of this utility model, the surface of the charging housing 1 near the mechanical locking groove 11 is provided with a connecting hole 18. Similarly, the surface of the sheet metal is also provided with a through hole that mates with the connecting hole 18. After the charging housing 1 is inserted into the mounting opening, the locking bolt 14 presses the charging housing 1 firmly into the mounting opening, improving the stability of the entire charging socket installation.

[0045] Furthermore, a limiting hole 115 is provided on the end face of the mechanical locking groove 11.

[0046] Specifically, during the actual charging process, the locking tongue of the charging gun mechanical lock is inserted into the limiting hole 115 to fix the charging gun; preferably, in order to prevent water from entering the limiting hole 115, the limiting hole 115 needs to be set away from the side wall.

[0047] A new energy charging socket includes the charging base with a drainage structure as described in the above embodiments.

[0048] In summary, this utility model introduces a charging base and a new energy charging socket with a drainage structure. This utility model can drain the water accumulated in the mechanical lock groove 11 through the drainage hole and drainage channel in the mechanical lock groove 11, preventing water from accumulating inside the mechanical lock groove 11 and causing it to freeze during car washing in winter, ensuring that the mechanical lock can be locked normally and the vehicle can be charged normally.

[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
