[0025] The working principle of the utility model is as follows:

[0026] In use, the electromagnetic lock shell 1 is fixed on the specified position of the intelligent charging pile socket through the mounting seat on the side of the electromagnetic lock shell 1, at this time, the coil 5 is not electrified, the magnet 6 generates upward magnetic attraction force on the iron core 4, and under the action of the elastic force of the spring 8, upward force is exerted on the lock shaft 2, so that the lock shaft 2 is in the folding state.

[0027] When the charging plug is plugged with the charging pile socket, the intelligent charging pile controller controls the current to pass through the coil 5, a magnetic field is generated, the magnet 6 is magnetized to generate magnetic force, the magnetic force of the magnet 6 is same with the magnetic force of the magnet 6, same polarity repulsion and different polarity attraction principle is utilized, downward force is exerted on the lock shaft 2, the elastic force of the spring 8 is overcome, the lock shaft 2 is moved downward to be plugged with the lock hole of the charging plug, and the separation of the charging plug and the intelligent charging pile socket is blocked.

[0028] During the moving down of the lock shaft 2, the slide post of the outer support plate 72 firstly slides in the vertical groove 732, limits the horizontal position of the outer support plate 72, avoids the outer support plate 72 from protruding the slide groove 71, and meanwhile the lower surface of the outer support plate 72 contacts with the conical curved surface of the conical disc 75, pushes the conical disc 75 and the connecting slide post 74 to move down together, the slide disc 76 slides in the limiting cylinder 77, and when the lower surface of the slide disc 76 contacts with the bottom wall of the limiting cylinder 77, the slide post of the outer support plate 72 slides to the intersection of the vertical groove 732 and the inclined groove 733;

[0029] With the continuous moving of the lock shaft 2, the conical disc 75 is pulled to slide relative to the lock shaft 2 by the connecting slide post 74 under the limitation of the bottom wall of the limiting cylinder 77, the conical curved surface of the conical disc 75 applies force to the lower end of the outer support plate 72, pushes the outer support plate 72 to move away from the center of the lock shaft 2, meanwhile the slide post of the outer support plate 72 slides in the inclined groove 733, pushes the outer support plate 72 to move in the horizontal direction away from the center of the lock shaft 2, makes the lower end of the outer support plate 72 protrude the outer curved surface of the lock shaft 2, until the rubber pad 10 contacts with the inner wall of the lock hole, supports the gap between the lock shaft 2 and the lock hole, reduces the relative movement between the lock shaft 2 and the lock hole, and makes the locking of the electromagnetic lock more firm.

[0030] Similarly, when the electromagnetic lock needs to be opened, the coil 5 is powered off, under the magnetic attraction of the magnet 6 and the elastic force of the spring 8, the lock shaft 2 moves up to reset, and meanwhile the lower end of the outer support plate 72 is folded into the slide groove 71.
