The cable sequentially passes through the auxiliary wire guide and the first main wire guide and extends out of the charging pile housing, and a charging plug is connected to the end of the cable. A driving mechanism capable of recovering the cable when the charging plug falls off is provided on the side of the winding base. When the charging plug is separated from the cable, the electrical control box can monitor the corresponding signal, cut off the power of the cable, brake the winding base through the driving mechanism and further control the reverse rotation of the winding base to recover the cable.

A plurality of ejector rods 47 are fixedly connected to the side of the moving plate 54 away from the fourth spring 48, and the plurality of ejector rods 47 are circumferentially arranged around the moving plate 54.

[0059] Working principle: Bolts are used to pass through the mounting holes on the fixing base 7 to fix the fixing base 7, thereby installing the charging pile main body 1. After installation, the buffer plate 8 faces the parking space.

[0060] During use, move the new energy vehicle to be charged to the charging pile main body 1. When the new energy vehicle is moving, if it accidentally touches the buffer plate 8, the buffer plate 8 will move towards the side close to the charging pile main body 1, causing the sliding rod 26 to slide into the interior of the charging pile main body 1 and stretching the fifth spring 27. The fifth spring 27 has a buffering effect on the buffer plate 8.

[0061] When the buffer plate 8 moves, it will push the first sliding plate 10 through the connecting rod 9. The first sliding plate 10 slides towards the side away from the buffer plate 8. The first sliding plate 10 will move closer to the corresponding second sliding plate 11 until the first sliding plate 10 contacts the corresponding second sliding plate 11.

[0062] The first sliding plate 10 will push the second sliding plate 11 towards the corresponding first fixing plate 12 together. The second sliding plate 11 will compress the sixth spring 13 for buffering again, thus playing a protective role for the charging pile main body 1.

[0063] After the new energy vehicle leaves the buffer plate 8, the contraction of the fifth spring 27 will pull the sliding rod 26 to slide, and the sixth spring 13 will stretch to push the second sliding plate 11 and the first sliding plate 10. Then the buffer plate 8 will pull the first sliding plate 10 through the connecting rod 9, and the first sliding plate 10 will gradually move away from the second sliding plate 11 until it returns to its original state.

[0064] After moving the new energy vehicle to a suitable position, rotate the protective cover 4 upward through the handle 5, so that the rotating shaft rotates on the connecting plate 20, and both ends of the rotating shaft rotate on the corresponding cover plates 2 respectively, driving the ratchet wheel 3 to rotate.

[0065] When the ratchet wheel 3 rotates, it will push the limit rod 15. The limit rod 15 will slide on the corresponding sliding block 17 and compress the first spring 16. At this time, the thrust of the first spring 16 is not sufficient to overcome the elastic force of the second spring 21 to make the sliding block 17 slide. Therefore, the sliding block 17 will not slide on the first chute 23, and the sealing plate 52 will not slide either. As the ratchet wheel 3 rotates, under the action of the elastic force of the first spring 16, it will continuously push the limit rod 15 towards the ratchet wheel 3, making the limit rod 15 always abut against the ratchet wheel 3.

[0066] After rotating the protective cover 4 to a suitable angle, stop rotating the protective cover 4. At this time, under the action of the elastic force of the first spring 16, it will push the limit rod 15, so that the arc end of the limit rod 15 is stuck between two teeth of the ratchet wheel 3, fixing the ratchet wheel 3, and thus fixing the position of the protective cover 4.

[0067] The hand-held charging plug 14 starts the first motor 25, and the output shaft of the first motor 25 rotates forward, driving the wire winding base 28 to rotate, gradually winding the cable 19 on the wire winding base 28 away. Pull the charging plug 14 outwards, so that the cable 19 passes through the rubber ring 33 and the guide block 18. The cable 19 will slide on the balls 31, causing the balls 31 to roll and gradually winding the cable 19 out of the charging pile main body 1. At the same time, the fixed disk 29 will also leave the guide rod 51.

[0068] The charging pile main body 1 controls the power connection to the cable 19, making the wire 50 energized. At this time, the electromagnet 49 is energized to generate magnetism, which will attract the moving plate 54, causing the moving plate 54 to slide inside the receiving groove 53 and compress the fourth spring 48. Until the moving plate 54 fits with the electromagnet 49, at this time, the ejector rod 47 is located inside the receiving groove 53. One end of the charging plug 14 can be inserted into the charging port of the new energy vehicle for charging through the wire 50.

[0069] During the charging process, if it is sunny, start the electric push rod 43. The telescopic rod at the output end of the electric push rod 43 extends downward, which will push the rack 41 downward. The rack 41 drives the gear 40 to rotate, causing the baffle 6 to rotate, driving the rubber ring 33 and the brush 35 to rotate until the baffle 6 is rotated away from the filter screen 36.

[0070] At this time, ventilation can be carried out inside the charging pile main body 1 through the filter screen 36, and the filter screen 36 can filter impurities in the air. The second motor 38 can also be started to make the fan blade 37 rotate, and the fan blade 37 blows air towards the filter screen 36 to further improve the ventilation effect. During the ventilation process, the baffle 6 can be driven by the electric push rod 43 to rotate reciprocally, so that the brush 35 scrapes off the impurities on one side of the filter screen 36.

[0071] If it is rainy during the charging process, the electric push rod 43 pulls the rack 41 upwards, causing the baffle 6 to rotate until the baffle 6 rotates to the filter screen 36 to block the second through hole. Similarly, the rubber ring 33 will seal the second through hole to reduce the entry of rainwater.

[0072] After the charging is completed, unplug the charging plug 14 from the charging port of the new energy vehicle. Start the first motor 25, and the output shaft of the first motor 25 rotates reversely, driving the wire winding base 28 to rotate, winding the cable 19 around the wire winding base 28, and driving the fixed disk 29 to move towards the outer side of the charging pile main body 1.

[0073] The charging plug 14 will move towards the protective cover 4. The fixed disk 29 will contact the guide rod 51 and push the guide rod 51 to slide into the charging pile main body 1, driving the connecting piece 24 to slide inside the charging pile main body 1. The sliding block 17 slides towards the side close to the second fixing plate 22 inside the first sliding groove 23, and the sealing plate 52 slides on the outer surface of the charging pile main body 1.

[0074] The sliding block 17 compresses the second spring 21 and drives the first spring 16 and the limiting rod 15 to move, causing the arc end of the limiting rod 15 to leave the ratchet wheel 3. At this time, the rotation of the ratchet wheel 3 is no longer restricted, so that the protective cover 4 rotates downward under the action of gravity, and then the protective cover 4 covers the charging plug 14, playing a role in protecting the charging plug 14.

[0075] After the protective cover 4 stops on one side of the charging pile main body 1, the first motor 25 stops. Since the first motor 25 does not have a brake device, it does not have self-locking. The reset action of the second spring 21 on the connecting member 24 will push the cable 19 to move a short distance outward from the charging pile main body 1, and the limiting rod 15 can be reset through the second spring 21 to lock the ratchet wheel 3.

[0076] If the charging plug 14 is forgotten to be unplugged after charging, the new energy vehicle will move the charging plug 14 away together. When pulling the charging plug 14, since one end of the cable 19 is located on the winding base 28, when it is pulled to the limit length, the collar 44 will squeeze the block 46. The block 46 slides into the inside of the groove and compresses the third spring 45 until one end of the charging plug 14 leaves the collar 44.

[0077] The wire 50 will leave the cable 19, causing the wire 50 to lose power, the electromagnet 49 to lose power and thus lose its magnetism, and no longer attract the moving plate 54. Under the action of the elastic force of the fourth spring 48, the moving plate 54 will be pushed to slide to the side away from the electromagnet 49, causing the ejector rod 47 to slide out of the receiving groove 53. One end of the charging plug 14 leaves the charging port of the new energy vehicle, and during the movement of the new energy vehicle, the ejector rod 47 is separated from the new energy vehicle and drops. This prevents the charging plug 14 from which the cable 19 has become disconnected from being taken away by the energy vehicle and being difficult to find, resulting in losses.

[0078] The charging plug 14 is made of impact-resistant materials such as rubber and soft plastic. This enables the charging plug 14 to continue to be used after falling, reducing losses.

[0079] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
