And every two clamping boss 21 is located on the same horizontal plane to carry the mobile plate 23 and the mobile guide rail 24 above the clamping boss 21.

[0029] Further, the mobile guide rail 24 includes a first sub-mobile guide rail 241 and a second sub-mobile guide rail 242, the first sub-mobile guide rail 241 is fixedly connected with the mobile plate 23, one side of the second sub-mobile guide rail 242 is movably installed on the first sub-mobile guide rail 241, the other side of the second sub-mobile guide rail 242 is movably installed on the guide slide rail 22. The first sub-mobile guide rail 241 and the second sub-mobile guide rail 242 are both installed in overlap, and the second sub-mobile guide rail 242 and the guide slide rail 22 are installed in overlap, that is, the second sub-mobile guide rail 242 is movably embedded in the guide slide rail 22, and the first sub-mobile guide rail 241 is movably embedded in the second sub-mobile guide rail 242. This installation method is conducive to reducing the installation space while retaining the moving range.

[0030] Specifically, when the moving plate 23 is forced to move outside the charging pile, the moving plate 23 drives the first sub-moving guide rail 241 to move along the direction of the second sub-moving guide rail 242. When the first sub-moving guide rail 241 moves to the end of the second moving guide rail 24, the first sub-moving guide rail 241 has an acting force on the second sub-moving guide rail 242, driving the second sub-moving guide rail 242 to move along the guide rail 22. Similarly, when the moving plate 23 is forced to move inside the charging pile, the moving plate 23 drives the first sub-moving guide rail 241 to move along the direction of the second sub-moving guide rail 242. When the first sub-moving guide rail 241 moves to the end of the second moving guide rail 24, the first sub-moving guide rail 241 has an acting force on the second sub-moving guide rail 242, driving the second sub-moving guide rail 242 to move along the guide rail 22. In this way, the moving plate 23 can move back and forth between inside and outside the charging pile.

[0031] Further, the first end and the second end of each guide rail 22 are recessed to form a clamping position. The clamping position is used to limit the movement range of the second sub-moving guide rail 242 on the guide rail 22. When the second moving guide rail 24 moves to the tail end or the head end of the guide rail 22, the clamping position blocks the movement path of the second sub-moving guide rail 242, avoiding the second moving guide rail from being separated from the guide rail 22, which can cause the moving plate 23 to fall, thereby reducing the risk of the moving plate 23 falling due to the second sub-moving guide rail moving too far.

[0032] Further, the connection between the clamping position and the guide rail 22 forms a semicircular arc shape. When the second sub-moving guide rail 242 moves to the front of the corresponding clamping position, the second sub-moving guide rail 242 moves forward along the semicircular arc shape, which can make the guide rail 22 move more smoothly and reduce friction and vibration caused by shape mutations. In addition, the semicircular arc shape design can make the guide rail 22 more evenly distribute pressure when bearing load, improve the overall carrying capacity, and ensure that the moving guide rail 24 can still move stably along the guide rail 22 when bearing a large load.

[0033] Further, a plurality of the positioning pins 231 are correspondingly distributed on the bottom of the moving plate 23. In this embodiment, each moving plate 23 is provided with four or more positioning pins 231, which are used to fix the master control board 3 on the moving plate 23. Four of the plurality of positioning pins 231 are correspondingly distributed on the four corners of the master control board 3, and the other positioning pins 231 can be distributed in the middle region of the master control board 3. The plurality of positioning pins 231 fix the corresponding master control board 3 from multiple positions, so that the plurality of positioning pins 231 can fix the corresponding master control board 3 on the moving plate 23 during use, thereby preventing the master control board 3 from falling off the moving plate 23, and prolonging the service life of the master control board 3.

[0034] Further, each master control board 3 is provided with a plurality of fixing holes, and each fixing hole is correspondingly inserted with a positioning pin 231. In this embodiment, each master control board 3 is provided with four or more fixing holes, and the positioning pins 231 are inserted into the corresponding fixing holes. The cooperation between the positioning pins 231 and the positioning holes provides strong constraint force, which helps to enhance the stability between components and reduce the relative displacement between the master control board 3 and the moving plate.

[0035] Further, the charging pile shell 1 is provided with a plurality of heat dissipation windows 11, and the plurality of heat dissipation windows 11 are located on opposite sides of the charging pile shell 1. In this embodiment, the charging pile can be provided with two heat dissipation windows 11, and the two heat dissipation windows 11 are located on the opposite two side walls of the charging pile, respectively. The heat dissipation window 11 is used to dissipate the heat inside the charging pile shell 1 to the external environment, and the two heat dissipation windows 11 are correspondingly distributed, so that the heat inside the charging pile is dissipated to the external environment by air convection, which helps to accelerate the heat dissipation efficiency of the charging pile and reduce the risk of overheating of the equipment.

[0036] Further, the inner wall of the charging pile shell 1 is provided with a plurality of wire grooves, and each wire groove correspondingly accommodates a connection line extended from the corresponding master control board 3. In this embodiment, the inner wall of the charging pile shell 1 is provided with a plurality of wire grooves, and the number of the wire grooves is determined according to the number of the master control boards 3. When the number of the master control boards 3 is larger, the number of the wire grooves is also larger. The wire grooves are used to accommodate the connection lines extended from the master control boards 3, so as to avoid the connection lines arranged in the charging pile shell 1 in disorder, which requires more time for the maintenance personnel to clear the lines during maintenance. This helps the maintenance personnel to reduce the steps of clearing the lines and accelerate the maintenance efficiency.

[0037] Further, the mounting frame 2 comprises a plurality of legs, each of which is attached to the inner wall of the charging pile shell 1. The mounting frame 2 comprises four legs, each of which is attached to the inner wall of the charging pile shell 1, and each of which is threadedly connected to the charging pile shell 1, so that each leg is fixed to the charging pile shell 1, thereby increasing the rigidity of the charging pile shell 1 and facilitating the enhancement of the structural stability of the charging pile shell 1 and the structural stability of the mounting frame 2.

[0038] Further, a plurality of charging guns 4 are arranged on the split DC charging pile, the plurality of charging guns 4 are electrically connected to the main control board 3, and each charging gun 4 is plug-removably connected to the charging pile shell 1. In this embodiment, the number of charging guns 4 is the same as the number of main control boards 3, one main control board 3 controls one charging gun 4, and when two main control boards 3 are arranged in the split DC charging pile, two charging guns 4 are arranged in the split DC charging pile. The charging gun 4 is plug-removably connected to the charging pile shell 1, and when the charging gun 4 is inserted into the corresponding position of the charging pile shell 1, the charging pile shell 1 clamps the charging gun 4, thereby preventing the charging gun 4 from falling off the charging pile shell 1 in a non-use state, facilitating reduction of the risk of damage caused by collision of the charging gun 4, and prolonging the service life of the charging gun 4.
