[0024] A method for using a charging pile for an electric vehicle that is easy to maintain, specifically comprising the following steps:

[0025] S1. When the user needs to charge the electric vehicle, the user pulls out the charging gun body and connects the charging gun body to the charging port of the electric vehicle. During this process, the charging port generates pressure on the protective sleeve, causing the protective sleeve to move toward the inside of the charging gun, and the protective sleeve drives the card slot to move. The card slot and the card block are engaged with each other, so that the position of the protective sleeve is relatively fixed. In addition, the protective sleeve drives the charging head to move inward, so that the charging head drives the power contact piece to move, so that the power contact piece and the power terminal contact each other, so that the charging head is energized. After charging is completed, the user presses the slide bar downward, so that the slide bar drives the card block to separate from the card slot, and the protective sleeve performs a reset movement driven by the fifth spring, so that the power contact piece is separated from the power terminal, so that the charging head is powered off;

[0026] S2. When the main body of the charging pile is in operation, the driving motor rotates forward, the driving motor drives the rotating shaft to rotate clockwise, the rotating shaft drives the rotating plate to rotate clockwise through the connecting platform, the rotating plate drives the fixed plate to move under the limit of the support, the fixed plate drives the fixed ring to rotate, the fixed ring drives the fixed box to rotate, the fixed box drives the connecting shaft to rotate, the connecting shaft cooperates with the rotating ring to drive the fan blades to rotate, and the heat inside the main body of the charging pile is dissipated through the heat dissipation cavity. When it rains, the driving motor rotates in the opposite direction, the driving motor drives the rotating shaft to rotate counterclockwise, and the rotating shaft drives the rotating plate to rotate counterclockwise through the connecting platform. At this time, the rotating plate is no longer limited by the support plate, so that the rotating shaft can drive the gear plate to rotate, the gear plate drives the transmission gear to rotate, the transmission gear drives the connecting shaft to rotate, and the connecting shaft drives the fan blades to rotate around the axis of the connecting shaft, so that the fan blades fit together and close, so that the heat dissipation cavity is closed, and rainwater is prevented from entering the main body of the charging pile;

[0027] S3. When the charging pile body needs to be repaired, the staff pulls the limit rod to separate the limit rod and the limit groove. Then, the staff rotates the connecting ring, and the connecting ring drives the extrusion block to rotate, so that the extrusion block and the extrusion wheel are separated from each other, so that the extrusion block releases the limit on the extrusion wheel. At this time, the third spring drives the moving rod to perform a reset movement, and the moving rod drives the insertion block to separate from the insertion groove, so that the insertion block releases the limit on the installation block. At this time, the staff pulls the handle to remove the charging pile body and replace the new charging pile body or repair the existing charging pile body. After completing the repair or replacement, the staff inserts the installation block into the connection and the installation groove. Then, the staff rotates the connecting ring, and the insertion block and the insertion groove are re-engaged through the transmission of the extrusion block, the extrusion wheel and the moving rod to complete the installation.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. In the present invention, by setting up the installation assembly, when the charging pile body needs to be replaced and repaired, the staff drives the extrusion block to rotate through the connecting ring, so that the extrusion block releases the limit on the extrusion wheel, and the third spring drives the insertion block to separate from the insertion slot through the moving rod, so that the insertion block releases the limit on the installation block. At this time, the staff pulls the handle to remove the charging pile body and replaces the new charging pile body or repairs the existing charging pile body. The moving rod is driven to move by the cooperation of the extrusion block and the extrusion wheel, and the connection and separation of the insertion block and the insertion slot are controlled by the movement of the moving rod, so that the installation block and the installation slot can be quickly disassembled and assembled, and the charging pile body can be easily disassembled and assembled, thereby facilitating the staff to perform maintenance on the charging pile body and reducing the maintenance difficulty and cost of the charging pile body.

[0030] 2. In the present invention, by setting a heat dissipation component, when the driving motor rotates forward, the driving motor drives the rotating plate to rotate clockwise through the rotating shaft, and the rotating plate drives the fixed ring to rotate through the fixed plate under the limit of the support, and the fixed ring drives the fan blades to rotate through the fixed box and the connecting shaft, and the fan blades dissipate the heat inside the charging pile body through the heat dissipation cavity. When it rains, the driving motor rotates in the opposite direction, and the driving motor drives the rotating plate to rotate counterclockwise through the rotating shaft. At this time, the rotating plate is no longer limited by the support plate, so that the rotating shaft can drive the transmission gear to rotate through the toothed disk, and the transmission gear drives the fan blades to rotate around the axis of the connecting shaft through the connecting shaft, so that the fan blades are fitted and closed to each other, thereby ensuring the sealing of the heat dissipation cavity, so that the charging pile body can be used in rainy open-air environments, thereby improving the applicability of the charging pile body in the environment.

[0031] 3. In the present invention, by setting a power-off component, when the charging gun body is charging the charging port, the charging port generates pressure on the protective sleeve, so that the protective sleeve drives the card slot to move, and the card slot and the card block are mutually engaged, so that the position of the protective sleeve is relatively fixed, and the protective sleeve drives the charging head to move inward, so that the charging head drives the power contact piece to move, so that the power contact piece and the power terminal contact each other, so that the charging head is energized. After charging is completed, the user presses the slide bar downward, so that the slide bar drives the card block to separate from the card slot, and the protective sleeve performs a reset movement driven by the fifth spring, so that the power contact piece is separated from the power terminal, so that the charging head is powered off, which can make the charging head in a power-off state when not in use, avoiding electric shock injuries to others caused by accidental touch of the charging gun body when not in use, thereby improving the safety of the charging gun body.
