[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-Figure 6 The liquid-cooled DC charging pile shown includes a charging pile 1, an output end of the charging pile 1 is electrically connected to a connecting wire 2, one end of the connecting wire 2 is electrically connected to a charging gun 3, and a storage component for winding up the connecting wire 2 is provided on one side of the charging pile 1. The storage component includes a winding frame 4 arranged on one side of the charging pile 1, the connecting wire 2 is sleeved in the middle of the winding frame 4, and the top and bottom of the winding frame 4 are symmetrically fixedly connected with connecting blocks 5 for limiting the movement of the connecting wire 2, one end of the connecting block 5 is fixedly connected to a blocking block 6, and a fixing component for fixing the position of the winding frame 4 is provided on one side of the charging pile 1.

[0024] It should be noted that the model of the charging pile 1, connecting cable 2 and charging gun 3 is DCL015A. Liquid cooling is a technology that dissipates heat by using liquid. Liquid cooling uses a liquid with high thermal conductivity to absorb heat and take it away by contacting the heat source of the equipment. When in use, the liquid cooling liquid flows through the charging equipment and battery through the cooling pipe, absorbs heat and takes it away, which can prevent the equipment from overheating and provide a more stable charging environment; the winding frame 4 is used to wind the connecting cable 2, and the connecting block 5 and the blocking block 6 form an L shape, which is used to confine the connecting cable 2 between the L shape and the winding frame 4.

[0025] Furthermore, when charging is completed, the connecting wire 2 is wound around the middle of the winding frame 4, the connecting wire 2 is collected and sorted through the winding frame 4, and then the connecting wire 2 is restricted by the connecting block 5 and the blocking block 6 to prevent the connecting wire 2 from slipping out of the winding frame 4, thereby preventing the connecting wire 2 from being randomly placed after use.

[0026] Specifically, a storage groove 7 is opened on one side of the charging pile 1 , and one side of the winding frame 4 is inserted and connected inside the storage groove 7 .

[0027] It should be noted that the storage groove 7 is annular and is used to store one end of the winding frame 4, so that when the connecting wire 2 is wound, the winding frame 4 is pushed into the storage groove 7, so that the blocking block 6 fits with the charging pile 1, thereby preventing the connecting wire 2 from slipping out of the gap between the blocking block 6 and the charging pile 1.

[0028] Specifically, a spring 8 is fixedly connected to one side of the charging pile 1 , and one end of the spring 8 away from the charging pile 1 is fixedly connected to the inner wall of the other side of the winding frame 4 .

[0029] It should be noted that the spring 8 is used to push the winding frame 4 to move. When the winding frame 4 needs to be pushed into the storage slot 7, the spring 8 is deformed. When the thrust on the winding frame 4 is lost, the spring 8 recovers its deformation and pushes the winding frame 4 to the side away from the storage slot 7, thereby driving the blocking block 6 away from the charging pile 1 through the winding frame 4.

[0030] Specifically, the fixing component includes a positioning seat 9 fixedly connected to one side of the charging pile 1, a rotation groove 10 is opened on the other side of the winding frame 4, an I-shaped block 11 is inserted and connected to the inner wall of one side of the rotation groove 10, and the positioning seat 9 is inserted and connected to the middle part of the spring 8.

[0031] Specifically, a connection groove 12 is formed on one side of the positioning seat 9 , and a circular clamping groove 13 for fixing the position of the I-shaped block 11 is formed on the inner wall of one side of the connection groove 12 .

[0032] Furthermore, when it is necessary to fix the position of the winding frame 4, the I-shaped block 11 inside the rotating groove 10 is rotated to align the edge of one side of the I-shaped block 11 with the connecting groove 12, and then the I-shaped block 11 is inserted into the connecting groove 12 so that one end of the I-shaped block 11 is inserted into the circular slot 13, and then the I-shaped block 11 is rotated to clamp one end of the I-shaped block 11 in the circular slot 13, so that the position of the winding frame 4 is fixed by the I-shaped block 11.

[0033] Specifically, a fixing seat 14 is horizontally and centrally symmetrically fixedly connected to one side of the charging pile 1, an extension groove 16 is opened on one side of the fixing seat 14, and an extension rod 15 for limiting the displacement direction of the winding frame 4 is horizontally and centrally symmetrically provided on the inner wall of the other side of the winding frame 4, and one end of the extension rod 15 is inserted and connected to the inside of the extension groove 16.

[0034] Specifically, one end of the extension rod 15 is horizontally and centrally symmetrically fixedly connected with a slider 18 for limiting the moving distance of the extension rod 15 , and the inner walls of the top and bottom of the extension groove 16 are symmetrically provided with slide grooves 17 , and the slider 18 is inserted and connected inside the slide groove 17 .

[0035] It should be noted that when the winding frame 4 moves, the extension rod 15 on one side of the winding frame 4 moves through the movement of the winding frame 4, and the extension rod 15 moves in the extension groove 16 on one side of the fixed seat 14; when the extension rod 15 moves in the extension groove 16, the slider 18 on the extension rod 15 moves in the slide groove 17 in the extension groove 16, and when one side of the slider 18 is in contact with the inner wall of one side of the slide groove 17, the slider 18 will not be able to move further.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
