[0037] Placing grooves are formed at the rear sides of both charging cabinets 1. Guide plates 25 are fixedly connected to the left and right sides of a number of charging ports near the top. Guide openings are formed in the guide plates 25. The tops of the guide openings are horizontally arranged, and the bottoms of the guide openings are arc-shaped. Z-shaped movable plates 30 are hinged to the horizontal portions of the two guide openings. A transmission rod 26 is commonly arranged through the arc-shaped portions of the two guide openings. The transmission rod 26 passes through the two Z-shaped movable plates 30. A second crank 29 is fixedly sleeved on the outer side of the transmission rod 26. The other side of the second crank 29 is hinged to a first crank 28. A number of opening and closing motors 27 are installed in the placing grooves.

The tops of the two Z-shaped movable plates 30 are commonly fixedly connected to an opening and closing door 2;

[0038] When the opening and closing motor 27 is started, the first crank 28 can be driven to move through the power output shaft. Under the influence of an external force, the first crank 28 can move on one side of the horizontal portion of the guide opening and enter the arc-shaped portion of the guide opening. When the first crank 28 enters the arc-shaped portion of the guide opening, the Z-shaped movable plate 30 can be driven to perform a 90-degree flip through the second crank 29. When the Z-shaped movable plate 30 performs a 90-degree flip, the opening and closing door 2 can be driven to flip, so that when the placing plate 12 moves close to the trigger 8, the opening and closing motor 27 can be started. When the opening and closing motor 27 is started, the opening and closing door 2 can be opened and the electric vehicle battery 7 can be sent to the inner cavity of the charging port for charging in cooperation with the reciprocating cylinder 16.

The buttons are electrically connected to the adjacent proximity triggers 8. The active sprocket 3, the driven sprockets 5, the chain 4, the sliding plate 10, the connecting plate 11 and the linkage block 9 can be shielded by the rain shield 6, preventing outdoor rainwater from directly impacting on the surfaces of the above components and causing damage to the components.

[0040] Working principle:

[0041] First, the staff presses the button to activate the corresponding proximity trigger 8, places the electric vehicle battery 7 on the top of the placement plate 12, with the front side of the electric vehicle battery 7 in contact with the F-shaped baffle 19, and starts the lifting motor 13. When the lifting motor 13 starts, the driving sprocket 3 can be driven to rotate through the power output shaft. When the driving sprocket 3 rotates, the chain 4 can be driven to move in cooperation with the driven sprocket 5. When the chain 4 moves, the linkage block 9 can be driven to move. When the linkage block 9 moves, the connecting plate 11 can be driven to move through the slide plate 10. The slide plate 10 contacts the clamping plate 31 to limit the movement track of the slide plate 10. When the connecting plate 11 moves, the placement plate 12 can be driven to move upward, and the electric vehicle battery 7 can be lifted upward. When the electric vehicle battery 7 moves to the vicinity of the adjacent proximity trigger 8, the proximity trigger 8 is triggered to start the corresponding opening and closing motor 27, realizing the lifting of the position of the electric vehicle battery 7, eliminating the staff's lifting step, reducing the physical consumption of the staff, and avoiding fatigue and even injury to the human arm and shoulder;

[0042] When the opening and closing motor 27 starts, the first crank 28 can be driven to move through the power output shaft. Under the influence of an external force, the first crank 28 can move on one side of the transverse direction of the guiding port and enter the arc-shaped side of the guiding port. When the first crank 28 enters the arc-shaped side of the guiding port, the Z-shaped movable plate 30 can be driven to rotate 90 degrees through the second crank 29. When the Z-shaped movable plate 30 rotates 90 degrees, the opening and closing door 2 can be driven to rotate, realizing that when the placement plate 12 moves to the vicinity of the proximity trigger 8, the opening and closing motor 27 can be started. When the opening and closing motor 27 starts, the opening and closing door 2 can be opened and the electric vehicle battery 7 can be sent to the inner cavity of the charging port for charging in cooperation with the reciprocating cylinder 16;

[0043] When the opening and closing door 2 rotates, the reciprocating cylinder 16 can be started. The reciprocating cylinder 16 can drive the moving plate 14 to move forward through the cross plate 15. When the moving plate 14 moves forward, the arc-shaped head 21 can be driven to move forward, so that the arc-shaped head 21 is inserted into the inner cavity of the limiting cylinder 23. When the arc-shaped head 21 contacts the limiting block 24, the limiting block 24 can be moved to fit with the rear side of the arc-shaped head 21. At this time, the connection between the moving plate 14 and the support plate 17 is completed, and the electric vehicle battery 7 is driven into the inner cavity of the charging port. When the electric vehicle battery 7 needs to be taken, the support plate 17 can be moved forward to fit with the placement plate 12, so that the rhombic ring 22 contacts the limiting block 24, and the separation between the moving plate 14 and the support plate 17 is completed, realizing that when the electric vehicle battery 7 moves to the vicinity of the proximity trigger 8, the electric vehicle battery 7 is moved into the inner cavity of the charging port to complete the charging of the electric vehicle battery 7, avoiding the situation that the staff's line of sight is blocked and it is difficult to accurately align.
