A heating block 25 is provided on the side of the semiconductor refrigeration plate 24 close to the control box 4, and a first cold conduction plate 26 is fixedly connected to the side of the semiconductor refrigeration plate 24 away from the heating block 25, and a second cold conduction plate 27 is fixedly connected to the side of the semiconductor refrigeration plate 24 away from the heating block 25. The sizes of the first cold conduction plate 26 and the second cold conduction plate 27 are adapted to the sizes of the control circuit board 5 and the charging circuit board 7. A plurality of heat dissipation holes 23 are opened on both sides of the control box 4, and a heat dissipation fan 28 is fixedly connected to both sides of the second cold conduction plate 27. The heat dissipation fan 28 blows the air in the control box 4 out of the heat dissipation holes 23.
[0022] Reference Figure 1-4As shown, this embodiment discloses that when charging a two-wheeled or three-wheeled electric vehicle, the user scans the QR code on the surface of the control box 4 of the bracket 1 to purchase the charging time. At this time, the display circuit board 6 at the display screen inside the control box 4 receives the signal of the control circuit board 5 through the cable, so that the socket 8 selected by the user displays the remaining charging time, and the control circuit board 5 also transmits a signal to the charging circuit board 7 through the cable, so that the socket 8 of the line selected by the user is energized, and then the user connects the charging line of the electric vehicle to the selected socket 8 to charge the electric vehicle. Before using the control box 4, move the semiconductor refrigeration sheet 24, put the first cold plate 26, the second cold plate 27, and the heating block 25 into the control box 4, and then move the heating block 25 to the preset through hole on the surface of the control box 4, so that the heating block 25 reaches the outside of the control box 4, and the fixing plate 22 on one side of the semiconductor refrigeration sheet 24 fits with the inner wall of the control box 4, and then turn the bolt 21 to make the bolt 21 pass through the fixing plate 22 and the control box 4 to fix the positions of the semiconductor refrigeration sheet 24, the first cold plate 26, the second cold plate 27, the heating block 25 and the cooling fan 28. At this time, the cooling fan 28 is at the heat dissipation hole 23 on the surface of the control box 4. Then, when using the control box 4, start the semiconductor refrigeration sheet 24, and then the temperature of the semiconductor refrigeration sheet 24 decreases, and the outside of the control block 4 is cooled. The heating block 25 in the upper part generates heat, and then the reduced temperature on the semiconductor refrigeration sheet 24 is sent to the control circuit board 5 and the charging electric board through the first cold conduction plate 26 and the second cold conduction plate 27 to quickly reduce the temperature of the control circuit board 5 and the charging electric board, and reduce the overall temperature inside the control box 4. At this time, the cooling fan 28 on the second cold conduction plate 27 is started to discharge the hot air inside the control box 4 from the heat dissipation holes 23 on the surface of the control box 4, thereby achieving the effect of quickly reducing the internal temperature of the control box 4. By using the heat dissipation device 2, the heat inside the control box 4 can be quickly dissipated to avoid the high internal temperature of the control box 4, which may cause damage to components on the circuit board inside the control box 4, thereby improving the use effect of the control box 4 and further improving the use effect of the charging pile.
[0023] Reference Figure 1-4As shown, the present embodiment discloses that the inner wall of the control box 4 is fixedly connected with a positioning block 29, and the size of the positioning block 29 is adapted to the size of the fixing plate 22. By using the positioning block 29, the position of the fixing plate 22 on the inner wall of the control box 4 can be quickly positioned, so that the fixing plate 22 can be conveniently installed and fixed using the bolt 21. A gasket 210 is abutted on one side of the bolt 21, and one side of the gasket 210 is abutted on the fixing plate 22. By using the gasket 210, the contact area of the fixing plate 22 of the bolt 21 is increased, so that the bolt 21 is not easy to loosen on the surface of the fixing plate 22, thereby improving the use effect of the bolt 21. A nut 211 is threadedly inserted at one end of the bolt 21 close to the outer wall of the control box 4, and the size of the nut 211 is adapted to the size of the bolt 21. By using the nut 211, the position of the bolt 21 is fixed for a second time, and then the bolt 21 is more firmly fixed on the control box 4.
[0024] Reference Figure 1-4 As shown, the present embodiment discloses that a limiting device 3 is provided on one side of the extension strip 8, and the limiting device 3 includes a slide rail 31, the slide rail 31 is fixedly connected to the extension strip 8, a sliding block 32 is slidably connected inside the slide rail 31, a clamping block 33 is inserted on one side of the sliding block 32, a clamping groove 34 is provided on one side of the slide rail 31, the clamping block 33 is clamped with the clamping groove 34 on the surface of the slide rail 31, and a limiting block 35 is fixedly connected to one side of the sliding block 32. After the vehicle's charging cable is connected to the socket strip 8, the sliding block 32 can be moved so that the limit block 35 on one side of the sliding block 32 is located on the side of the charging cable plug away from the socket strip 8, and the plug of the charging cable is blocked and limited. Then the card block 33 is moved so that the card block 33 passes through the sliding block 32 and reaches the inside of the card groove 34 on the surface of the slide rail 31 to fix the position of the limit block 35. By using the limit device 3, the position of the charging cable plug can be blocked and limited after being connected to the socket strip 8, so as to avoid the charging cable plug being accidentally separated from the socket strip 8 due to force, which then affects the user's charging, thereby improving the use effect of the charging pile.
[0025] Reference Figure 1-4 As shown, this embodiment discloses that one side of the block 33 is fixedly connected with a connecting rope 36, and the side of the connecting rope 36 away from the block 33 is fixedly connected to the sliding block 32. By using the connecting rope 36, the block 33 is connected to the sliding block 32 to avoid the block 33 from being lost. The inside of the slide rail 31 is fixedly connected with an arc block 37, and the surface of the arc block 37 is smooth. By using the arc block 37, the friction between the slide rail 31 and the sliding block 32 is reduced, so that the sliding block 32 can slide more easily inside the slide rail 31. One side of the sliding block 32 is fixedly connected with an auxiliary block 38, and the cross-section of the auxiliary block 38 is annular. By using the auxiliary block 38, the contact area between the user and the sliding block 32 is increased, so that the sliding block 32 can be more easily held and moved by the user.
[0026] Working principle: When charging a two-wheeled or three-wheeled electric vehicle, the user will scan the QR code on the surface of the control box 4 of the bracket 1 to purchase the charging time. At this time, the display circuit board 6 at the display screen inside the control box 4 receives the signal of the control circuit board 5 through the cable, allowing the socket 8 selected by the user to display the remaining charging time. The control circuit board 5 also transmits a signal to the charging circuit board 7 through the cable, so that the socket 8 of the line selected by the user is energized, and then the user connects the charging cable of the electric vehicle to the selected socket 8 to charge the electric vehicle. Before using the control box 4, move the semiconductor refrigeration sheet 24, put the first cold plate 26, the second cold plate 27, and the heating block 25 into the control box 4, and then move the heating block 25 to the preset through hole on the surface of the control box 4, so that the heating block 25 reaches the outside of the control box 4, and the fixing plate 22 on one side of the semiconductor refrigeration sheet 24 fits with the inner wall of the control box 4, and then turn the bolt 21 to make the bolt 21 pass through the fixing plate 22 and the control box 4 to fix the positions of the semiconductor refrigeration sheet 24, the first cold plate 26, the second cold plate 27, the heating block 25 and the cooling fan 28. At this time, the cooling fan 28 is at the heat dissipation hole 23 on the surface of the control box 4. Then, when using the control box 4, start the semiconductor refrigeration sheet 24, and then the temperature of the semiconductor refrigeration sheet 24 decreases, and the outside of the control block 4 is cooled. The heating block 25 in the upper part generates heat, and then the reduced temperature on the semiconductor refrigeration sheet 24 is sent to the control circuit board 5 and the charging electric board through the first cold conduction plate 26 and the second cold conduction plate 27 to quickly reduce the temperature of the control circuit board 5 and the charging electric board, and reduce the overall temperature inside the control box 4. At this time, the cooling fan 28 on the second cold conduction plate 27 is started to discharge the hot air inside the control box 4 from the heat dissipation holes 23 on the surface of the control box 4, thereby achieving the effect of quickly reducing the internal temperature of the control box 4. By using the heat dissipation device 2, the heat inside the control box 4 can be quickly dissipated to avoid the high internal temperature of the control box 4, which may cause damage to components on the circuit board inside the control box 4, thereby improving the use effect of the control box 4 and further improving the use effect of the charging pile.
[0027] After the vehicle's charging cable is connected to the socket strip 8, the sliding block 32 can be moved by the auxiliary block 26, so that the limit block 35 on one side of the sliding block 32 is located on the side of the charging cable plug away from the socket strip 8, and the plug of the charging cable is blocked and limited. Then, the card block 33 with the connecting rope 36 is moved to make the card block 33 pass through the sliding block 32 and reach the inside of the card groove 34 on the surface of the slide rail 31 to fix the position of the limit block 35. By using the limit device 3, the position of the charging cable plug can be blocked and limited after being connected to the socket strip 8, so as to avoid the situation where the charging cable plug is accidentally separated from the socket strip 8 due to force, and then the user's charging is affected, thereby improving the use effect of the charging pile.
