The working principle is as follows:

when the electric vehicle charging device is used, the charging mechanism 6 slides to the position of the electric vehicle to be charged through the driving motor or the manual control pulley 31, the winding motor 52 of the winding mechanism 5 is opened, the winding roller 53 fixedly connected with the output end is driven to rotate, and the transmission line 43 wound on the winding roller 53 is put down; then, the movable handle 62 on the charging mechanism 6 is pressed down to make the power transmission line 43 fully contact with the discharging head 64, and the current in the charging pile is transmitted into the first sliding contact line 112 through the power transmission line and then transmitted onto the electric brush 41, and is transmitted into the power transmission line 43 through the connector 42 fixedly connected to the electric brush 41; since the power transmission line 43 is in contact with the discharge head 64, current flows into the discharge head 64; the charging gun body 61 of the charging mechanism 6 is inserted into an electric automobile, the discharging head 64 is used for charging the automobile, and finally after charging is completed, the winding motor 52 of the winding mechanism 5 is opened to drive the winding roller 53 to rotate, the transmission line 43 is wound up, and the device is put back to the original position.

If the charging mechanism 6 on one circular track 1 cannot meet the requirement of charging the electric vehicle in the area (for example, if the charging mechanism 6 on the left circular track 1 shown in fig. 1 is insufficient), the charging mechanism 6 on the right circular track 1 is firstly slid onto the moving track 217 connected with the circular track 1 (i.e., the moving track 217 at the middle position shown in fig. 1) by the driving motor or the manual control pulley 31, and then the servo motor 212 is started to drive the lead screw 213 to rotate, so as to drive the wang-shaped moving slide rail 2 to move towards the right side in the direction shown in fig. 1, so that the moving track 217 at the middle position is connected with the opening of the left circular track 1, and the charging mechanism 6 on the right circular track 1 is transferred onto the left circular track 1. Meanwhile, in the moving process of the moving track 217, the toggle block 111 is controlled to move in a direction away from the moving track 217, so that the lifting rod 228 returns to the initial position, that is, the lifting rod 228 is perpendicular to the telescopic rod 222 (as shown in the left side of fig. 5); after moving (namely after the opening of the moving track 217 is matched with the opening of the circular track 1), the shifting block 111 is controlled to move towards the direction close to the moving track 217, the shifting block 111 abuts against the telescopic rod 222 to move, the return spring 223 is compressed, the rack 224 moves along with the telescopic rod 222 and drives the gear 225 to rotate, so as to drive the lifting rod 228 to rotate, when the lifting rod 228 rotates to a position parallel to the telescopic rod 222 (shown on the right side of fig. 5), the shifting block 111 stops moving, and when the lifting rod 228 is parallel to the telescopic rod 222, the second sliding block 33 cannot be limited, so that the running stability of the circular track 1 when being connected with the moving track 217 is effectively ensured; when the shifting block 111 moves in a direction away from the moving track 217, that is, when the shifting block 111 does not prop against the telescopic rod 222, the lifting rod 228 returns to the initial position due to the return of the return spring 223, so that when the circular track 1 is separated from the moving track 217 of the "king" shaped moving slide rail 2, the lifting rod 228 can effectively limit the position of the second slider 33 of the sliding mechanism 3 on the moving track 217, and the problem that the second slider 33 is separated from the moving track 217 due to vibration or inertia generated during movement is avoided.

When the moving rail 217 at the middle position shown in fig. 1 is separated from the right circular rail 1, the second trolley wire 2171 is separated from the first trolley wire 112, and since the arc-shaped conductive block 2173 is connected with the arc-shaped groove 114, the second trolley wire 2171 can move smoothly with the first trolley wire 112, and the telescopic spring 2172 is compressed; similarly, when the arc-shaped conductive piece 2173 contacts the moving rail 217 and the outer wall of the beam 11, the extension spring 2172 compresses and the arc-shaped conductive piece 2173 slides smoothly with it. Through the connection between the arc-shaped conductive block 2173 and the arc-shaped groove 114, fibers of the moving track 217 and the beam 11 are realized, meanwhile, the contact area is increased, the condition that a sliding contact line between the moving track 217 and the beam 11 is greatly discharged or short-circuited due to insufficient contact of the contact surface is avoided, and meanwhile, the structure of the telescopic spring 2172 is matched to ensure the smoothness in the moving process, so that the moving clamping stagnation is avoided.
