Referring to fig. 1 and 2, the present invention is a charging pile with an automatic winding function, including a charging pile body 1 and a winding mechanism located inside the charging pile body 1, where the winding mechanism includes a plurality of screw rods 2 arranged side by side, slide rails 3 corresponding to the screw rods 2 one by one, and a sliding plate 4.

As shown in fig. 3 to 5, the number of the screw rods 2 may be four or more, and the end of the screw rod 2 is fixedly connected with a driven wheel 201. The lead screw 2 is connected with the inner side wall of the electric pile body 1 through a bearing seat, and the slide rail 3 is fixedly connected with the inner side wall of the electric pile body 1 through a screw.

Each lead screw 2 all is connected with two nuts in the cooperation, and the nut is connected with the slider 301 with 3 sliding connection of slide rail for rotate through lead screw 2, drive two sliders 301 synchronous dorsad and remove in opposite directions.

Two sliders 301 all have the connecting plate through bolted connection, install U type grooved pulley group 302 on the connecting plate for pass the wire by four lead screws 2 on two sliders 301U type grooved pulley group 302 in proper order, make wire 6 become snakelike coiling.

As shown in fig. 5, the U-shaped groove wheel set 302 includes two U-shaped groove wheels, and the two U-shaped groove wheels are arranged side by side along the axial direction of the lead screw 2, and the wire 6 passes through the U-shaped groove wheel set 302 on the right side, passes through the U-shaped groove wheel set 302 on the left side, passes through the U-shaped groove wheel set 302 on the right side on the lead screw 2 on the upper side, and so on, and the wire 6 passes through the charging pile body 1 and is connected with the charging gun.

The sliding plate 4 is connected with the inner wall of the charging pile body 1 in a sliding mode, the sliding plate 4 is connected with a rack 401 meshed with the driven wheel 201 in a welding mode or in a screw connection mode, and the driving mechanism is connected in a transmission mode and used for driving the sliding plate 4 to move along the radial direction of the lead screw 2 through the driving mechanism and meshed with the driven wheel 201 through the rack 401 to drive the lead screw 2 to rotate.

The driving mechanism comprises a lead screw 501 rotatably connected with the inner wall of the charging pile body 1 and a driving motor 5 in transmission connection with the lead screw 501, the sliding plate 4 is fixedly connected with a lead screw nut matched with the lead screw 501, and the driving motor 5 drives the lead screw 501 to rotate so as to realize the movement of the sliding plate 4.

And, during the movement of the sliding plate 4, the rack 401 is meshed with one of any two adjacent driven wheels 201, so that the sliding plate 4 only drives one screw rod 2 to rotate at a time.

As shown in fig. 6, the length of the rack 401 is equivalent to the distance between the driven wheels 201 at the ends of two adjacent lead screws 2, when charging is needed, the driving motor 5 is started, the sliding plate 4 moves downwards, the rack 401 is engaged with the driven wheel 201 connected with the lead screw 2 at the uppermost layer, and as the sliding plate 4 moves downwards, the lead screws 2 rotate, so that the two sliding blocks 301 move towards each other, and as the distance between the two sliding blocks 301 decreases, the conducting wire 6 is released, and the conducting wire 6 is conveniently pulled out of the charging pile body 1.

When the sliding plate 4 moves downwards, the rack 401 is separated from the driven wheel 201 connected with the lead screw 2 on the uppermost layer, at the moment, the rack 401 is meshed with the driven wheel 201 connected with the lead screw 2 on the next layer, if the length of the lead wire 6 is insufficient, the sliding plate 4 continues to move downwards, the lead screw 2 on the next layer is driven to rotate, the two sliding blocks 301 connected with the lead screw 2 on the next layer move oppositely to release the lead wire 6, the lead wire 6 can continue to be pulled outwards, the downward movement of the sliding plate 4 is analogized in sequence, the lead screw 2 on each layer is driven to rotate in sequence, the lead wire 6 is released in sequence until the lead wire with a sufficient length is charged for use, the length of the lead wire 6 is flexibly released according to the use condition, and the overall use convenience is effectively improved.

After the completion of charging, the sliding plate 4 moves up, and the lead screw 2 of each layer is driven in proper order from bottom to top to rotate, so that the two sliders 301 connected with the lead screw 2 move back to back, thereby realizing the effect of pulling the lead 6 inwards from the outside of the charging pile body 1, realizing the storage of the lead 6, and after the sliding plate 4 moves to the uppermost end to reset, finishing the take-up of the lead 6.

Meanwhile, as shown in fig. 6, the U-shaped grooved pulley sets 302 on the two sliders 301 connected to the same lead screw 2 are distributed vertically. Specifically, when rack 401 with from the meshing of driving wheel 201, drive lead screw 2 and rotate for two sliders 301 remove in opposite directions, at this moment, when rack 401 with from the driving wheel 201 separation, U type grooved pulley group 302 on two sliders 301 is located just right position from top to bottom, thereby makes wire 6 become vertical state between two U type grooved pulley group 302, thereby avoids wire 6 to produce and buckles, leads to the inconvenient condition of user pulling wire 6 outwards to take place.
