When it is necessary to lift the frame 2 to make the power supply body 5 close to the charging interface of the car to be charged, the pressing plate 80 drives the control board 79 to move down, and the control board 79 drives the locking block 71 to move to the right through the connecting rod 77 to disengage from the locking slot 75. The buffer plate 47 pushes the moving frame 41 to move to the right under the elastic force of the buffer spring 49, so that the frame 2 is separated from the base 1, and the frame 2 is moved upward. 44 is separated, the moving frame 41 on the lower side is pulled upward and separated from the friction plate 44. At this time, the moving frame 41 can move freely in the chute 42, the moving frame 41 moves to the right, and the first support rod 8 rotates clockwise , the second support rod 8a rotates clockwise and counterclockwise, the frame 2 is lifted to an appropriate height and the frame 2 is released, and the frame 2 exerts downward pressure on the first support rod 8 and the second support rod 8a under the action of gravity, then The moving frame 41 on the upper side is pressed upward and is in close contact with the friction plate 44 , and the first support rod 8 is fixed under the action of friction, while the moving frame 41 on the lower side is pressed downward and is in close contact with the friction plate 44 , under the action of friction force, the second support rod 8a is fixed to realize the function of fixing the height of the frame 2 .

When it is necessary to lower the frame 2, push the push plate 60 inward, the push plate 60 moves inward and drives the inclined block 59 to move outward, the outer end of the inclined block 59 enters the groove 56, and at the same time the outer end of the inclined block 59 pushes the pressure plate 54 Separate the inner end of the pressure plate 54 from the outer end of the sliding frame 51, continue to push the push plate 60 to drive the sliding frame 51 to move into the chute 42, and the sliding frame 51 drives the moving frame 41 to separate from the friction plate 44, then the sliding frame 51 loses friction After the force is limited, the frame 2 descends rapidly under the action of its own gravity, and when the frame 2 descends to the point of contact with the upper end of the base 1, the buffer plate 47 decelerates the moving frame 41 and prevents the moving frame 41 under the elastic force of the buffer spring 49. Move to the left end of the chute 42, the frame 2 will maintain the height of the upper side of the base 1, if you need to lock the frame 2 on the base 1, press down the frame 2, the locking groove 75 is moved to the locking block 71, lock The block 71 is reset and snapped into the locking groove 75 under the elastic force of the spring 73, and the lower end of the frame 2 is in contact with the first support rod 8 and the second support rod 8a, then the moving frame 41 is subjected to external force to move in the vertical direction, The carriage 51 overcomes the frictional force with the pressure plate 54 and is reset.
