[0063] In addition, because the outer end top of the two movable limiting rods 601 is provided with a small round corner, and the bottom of the two movable sealing frames 301 is provided with a round corner, when the two movable sealing frames 301 slide downwards and reset, the two movable limiting rods 601 can slide inward under the action of the two small round corners, so that the two movable limiting rods 601 are separated from the two circular limiting grooves 1011; when the battery 200 is in the charging state, and the staff pulls the protective top plate 701 upwards, the two movable sealing frames 301 cannot be positioned by the four circular iron blocks 103 and the four circular electromagnets 303, so that when the staff releases the protective top plate 701, the pile body 700 automatically falls into the protective shell 101 under the action of gravity, so that the staff cannot use the pile body 700 when the battery 200 is charging.

[0064] The application provides a convenient mobile electric vehicle charging pile, which comprises a pile body 700 and a protection top plate 701, and further comprises a battery management device, the pile body 700 is fixedly installed on the battery management device, and the pile body 700 is electrically connected with a battery 200; the protection top plate 701 is fixedly installed on the top of the pile body 700.

[0065] The specific action is that: because the pile body 700 is fixedly installed on the rectangular connecting plate 302, and the protection top plate 701 is fixedly installed on the top of the pile body 700, the pile body 700 can be moved out of the protection shell 101 when the pile body 700 is used, and the pile body 700 can be stored in the protection shell 101 when the pile body 700 is not used, thereby achieving the storage and protection effect of the pile body 700.

[0066] The specific use mode and action of the embodiment are as follows:

[0067] The worker connects the charger with the charging socket 201 and the socket respectively, and fully charges the battery 200; when the battery 200 is in the charging state, the control switch 504 is not pressed, and at this time, the four circular electromagnets 303 do not have magnetic force; when the battery 200 is in the charging state, and the worker pulls the protection top plate 701 upward, the two movable sealing frames 301 cannot be positioned by the four circular iron blocks 103 and the four circular electromagnets 303, so that when the worker releases the protection top plate 701, the pile body 700 automatically falls into the protection shell 101 under the action of gravity, thereby ensuring that the worker cannot use the pile body 700 when the battery 200 is charging; then the worker places the convenient mobile electric vehicle charging pile in the trunk of the electric vehicle,

[0068] When the mobile electric vehicle charging pile is needed to be used, the staff adjusts the position of the protection shell 101 through the four rollers, makes the protection shell 101 close to the charging position of the electric vehicle, then pulls the protection top plate 701 upwards, and the pile body 700 is moved out of the protection shell 101. When the four circular electromagnets 303 are in the energized state and the two movable sealing frames 301 slide upwards, the four circular electromagnets 303 can be concentric with the four circular iron blocks 103, and the two movable sealing frames 301 are positioned, so that the two movable sealing frames 301 can be in a stable state after sliding upwards. When the four circular electromagnets 303 are concentric with the four circular iron blocks 103, the six rows of grooves on the protection shell 101 are aligned with the six rows of grooves on the two movable sealing frames 301, which is conducive to heat dissipation in the protection shell 101. When the two movable sealing frames 301 slide upwards, the four stable anti-moving frames 403 change the angle under the action of the four spiral springs a 404, so that the bottom end of the four stable anti-moving frames 403 is in contact with the ground, which plays an auxiliary braking effect on the protection shell 101 and increases the stability during use. When the battery 200 is charging, the staff needs to pull the shielding control plate 503 upwards. When the battery 200 is in the charging state, the control switch 504 is released, at this time, the four circular electromagnets 303 do not have magnetic force. When the two movable sealing frames 301 slide upwards, under the action of the two large circular angles, the two movable sealing frames 301 can push the two movable limiting rods 601 to move inward, so that the two movable limiting rods 601 are separated from the two rectangular limiting grooves 3011. When the two movable sealing frames 301 slide upwards, the two movable limiting rods 601 are inserted into the two circular limiting grooves 1011 under the action of the two spiral springs b 604, at this time, the staff cannot pull the shielding control plate 503 upwards, which ensures that the staff cannot charge the battery 200 when the pile body 700 is used.

[0069] After the convenient mobile electric vehicle charging pile is used, the staff presses down the protection top plate 701, when the pile body 700 is not used, the pile body 700 can be stored in the protection shell 101, and the storage protection effect of the pile body 700 is achieved; when the circular electromagnet 303 is separated from the four circular iron blocks 103, the six rows of groove holes on the protection shell 101 are separated from the six rows of groove holes on the two movable sealing frames 301, which is beneficial to improve the protection effect of the protection shell 101; when the two movable sealing frames 301 are reset by sliding downward, the two movable sealing frames 301 can press the four stable anti-moving frames 403, so that the four stable anti-moving frames 403 change the angle, the automatic separation of the four stable anti-moving frames 403 and the ground is realized, and the staff can move the protection shell 101 through the four rollers; when the two movable sealing frames 301 are reset by sliding downward, the two movable limiting rods 601 can slide inward under the action of the two small round corners, so that the two movable limiting rods 601 are separated from the two circular limiting grooves 1011.

[0070] The above examples are only used to illustrate the technical solutions of the present disclosure, but not to limit it; although the present disclosure has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
