[0028] like Figures 1 to 6 As shown, a charging stand air-cooling structure shown in this embodiment includes a heat dissipation shell 1 with a cavity 10 and a socket assembly 2 and a cable 3 respectively arranged at the front and rear ends of the heat dissipation shell 1, wherein two jack terminals 21 are arranged in the socket assembly 2, and the rear ends of the jack terminals 21 extend backward into the cavity 10 and are suspended, and there are two cables 3, and the front ends of the two cables 3 are inserted into the cavity 10 and are respectively connected with the two jack terminals 21 in a one-to-one correspondence, and a thermal conductive silicone sheet 4 is respectively provided between the two jack terminals 21 and the heat dissipation shell 1; in the above, the thermal conductive silicone sheet is used to increase the heat conduction contact area and conduction efficiency between the jack terminal and the heat dissipation shell, and the heat generated by the jack terminal during work is quickly transferred to the heat dissipation shell by utilizing the fast conduction performance of the thermal conductive silicone, thereby effectively increasing the heat dissipation area and heat dissipation speed, achieving a good heat dissipation effect, and will not affect the performance of the jack terminal.

[0029] A wire nose 31 is crimped at the front end of the cable 3. The wire nose 31 is placed above the socket terminal and fixed to the socket terminal 21 by means of screws 5. The wire nose and the socket terminal are fixed by screws to ensure the reliability of the connection and facilitate assembly and disassembly of the two.

[0030] A plastic head 6 is provided on the cable 3 through an interference fit sleeve, and the plastic head 6 is threadedly connected to the heat dissipation shell 1, so that the cable is fixed to the rear end of the heat dissipation shell, which is convenient for the assembly and disassembly of the cable; a self-locking nut 61 is also provided on the plastic head 6, and the self-locking nut 61 is arranged on the outside of the heat dissipation shell 1. After the plastic head is fixed on the heat dissipation shell, the self-locking nut is tightened toward the heat dissipation shell, so as to lock the plastic head to prevent the plastic head from loosening and falling off, thereby ensuring the stability and reliability of the connection.

[0031] The upper end of the cavity 10 is open, which is convenient for assembling the jack terminal and the wire nose in the cavity. The upper end of the heat dissipation shell 1 is provided with a cover plate 7 covering the opening of the cavity 10, and a waterproof ring 8 is provided between the cover plate 7 and the heat dissipation shell 1, so that the sealing inside the cavity is good and meets the waterproof requirements.

[0032] In the present embodiment, a detachable fan 9 is provided on the outside of the heat dissipation housing 1 corresponding to the thermally conductive silicone sheet 4; specifically, the thermally conductive silicone sheet 4 is provided between the bottom of the cavity 10 and the jack terminal 21, and the fan 9 is provided at the bottom of the heat dissipation housing 1, so as to directly cool down the surface of the heat dissipation housing in contact with the thermally conductive silicone sheet, and a plurality of fins 11 extending downward and arranged at intervals are also provided around the bottom of the heat dissipation housing 1, and the fan 9 is placed in the middle of the fins 11 around, that is, the fan is surrounded by the fins on all sides; in the above, the fan is used to suck wind (air) and blow the heat dissipation housing inward, so as to quickly cool down the heat dissipation housing, and the fan is provided on the outside of the heat dissipation housing corresponding to the thermally conductive silicone sheet, so as to cool down the heated side of the heat dissipation housing in the first place, so as to effectively improve the heat dissipation effect, and a plurality of fins arranged at intervals are provided on the heat dissipation housing around the fan, and air flow channels are formed between the fins, so that the wind (air) blown inward by the fan flows out from between the fins, and then the heat is taken out from between the fins around (such as Figure 7 As shown), the fins increase the heat dissipation contact area between the wind used for heat dissipation and the heat dissipation shell, further improving the heat dissipation effect.

[0033] The socket assembly 2 is fixed to the heat dissipation housing 1 by screws, and a waterproof ring (not shown in the figure) is provided between the socket assembly and the heat dissipation housing; a socket cover 22 for covering the plug interface is hingedly connected to the front end of the socket assembly 2, one end of the socket cover 22 is hingedly connected to one side of the socket assembly, and a lock 23 for fixing the other end of the socket cover is provided on the other side of the socket assembly.

When the resistance is relatively large, the air inside the heat dissipation shell is discharged from the through hole by pulling out the sealing plug, thereby reducing the plugging resistance between the socket assembly and the plug, so that the two can be plugged smoothly; in addition, when water accidentally enters the heat dissipation shell, the sealing plug is pulled out to allow the water to flow out of the through hole.

[0036] In this embodiment, the four corners of the bottom of the heat dissipation housing 1 are further provided with mounting feet 13 for fixing, so as to facilitate the installation and fixing of the heat dissipation housing on the corresponding external equipment (such as electric vehicles, charging piles, etc.).

[0037] In this embodiment, the heat dissipation housing 1 is made of metal (steel, iron or aluminum alloy, etc.) and is integrally formed to facilitate heat dissipation.

[0038] The specific assembly steps of the above charging station air cooling structure are as follows:

[0039] (1) Attach two thermally conductive silicone sheets symmetrically to the corresponding positions at the bottom of the inner cavity of the heat dissipation housing;

[0040] (2) Install the socket assembly on the front end of the heat dissipation housing and secure it with screws;
