[0014] The present invention provides a charging pile with a self-protection function. It has the following beneficial effects: (1) In this invention, when the clamping block slides, the fixation with the electric vehicle will be released. Then, when the charging head is pulled when the electric vehicle drives away, the fixation between the charging head and the electric vehicle will be quickly released, avoiding the cable from being pulled. The cable may be damaged or the circuit may be short-circuited due to the pulling. Allowing the charging head to quickly detach when subjected to a pulling force can prevent the cable from being over-stretched or damaged, thereby protecting the safety and service life of the cable.

[0015] (2) In this invention, when the protection plate rotates, it will drive the anti-collision plate to rotate. Then, when the charging head detaches from the electric vehicle and falls to the bottom, the anti-collision plate will protect the charging head. The protection plate can effectively reduce the impact force of the charging head directly colliding with the ground, reducing the damage to the internal circuit, interface or shell of the charging head during the fall.

[0016] (3) In this invention, when the sliding arc plate moves, it will drive the sliding insertion rod to move. When the sliding insertion rod moves, the limit on the rotating sleeve will be released. Then, the rotating sleeve will be driven by the third torsion spring to rotate towards the direction of the rotary handle. Then, the rotating sleeve will wrap and protect the rotary handle. When the rotary handle impacts the ground, the wrapping protection can effectively absorb part of the impact force, reducing the damage to the surface, structure and internal components of the rotary handle.

[0017] (4) In this invention, the sealing plate will wrap and seal the charging head, preventing the outside from raining when the charging head falls to the ground. If the charging head is exposed to rainwater, moisture may enter the interior of the charging head, especially the electrical part, which may cause short circuits, corrosion or other electrical faults, affecting the normal operation of the charging head and even potentially causing safety hazards such as fires. The wrapping and sealing can effectively block the intrusion of moisture and reduce these risks.

[0018] (5)In this invention, when the rotating scraper rotates, it will scrape and clean the charging head. After the charging head falls to the ground, dust, sand, oil stains or other sundries may adhere to its surface. If not cleaned, these substances may enter the interface or circuit of the charging head, affecting the charging contact points and even potentially causing short circuits or other faults. Scraping and cleaning helps remove surface sundries and reduce the risk of these substances entering the interior. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The anti-pulling device further includes a sliding block 11, a fixing frame 12, a sliding key 13 and a sliding buckle 14. The sliding block 11 is fixedly installed on the outer wall of the cable 2, the sliding block 11 slidably penetrates the outer wall of the protective shell 4, the fixing frame 12 is fixedly installed on the outer wall of the protective shell 4, the sliding key 13 is slidably installed on the inner wall of the fixing frame 12, the sliding buckle 14 is slidably installed at the bottom of the fixing frame 12. When the cable 2 is pulled, it may be damaged or the circuit may be short-circuited due to the pulling. Allowing the charging head 3 to quickly disengage when subjected to a pulling force can avoid excessive stretching or damage of the cable 2, thereby protecting the safety and service life of the cable 2.

[0024] A first torsion spring is provided between the turning handle 10 and the handle 5. The first torsion spring is provided to drive the turning handle 10 back to its original position. A first spring is provided between the arc-shaped plate 8 and the protective shell 4. The first spring is provided to drive the arc-shaped plate 8 back to its original position. A second spring is provided between the fixing frame 12 and the sliding key 13. The second spring is provided to drive the sliding key 13 to move. A third spring is provided between the sliding key 13 and the sliding buckle 14. The third spring is provided to drive the sliding buckle 14 to move. A card slot is provided on the side of the sliding key 13 close to the sliding buckle 14, and the outer shape of the sliding buckle 14 matches the card slot.

[0025] During the operation of this embodiment: When it is necessary to charge the tram, press and turn the handlebar 10. The rotation of the handlebar 10 will push the push rod 9 to move. The movement of the push rod 9 will push the arc plate 8 to move. The movement of the arc plate 8 will drive the connecting rod 7 to move. The movement of the connecting rod 7 will drive the latch 6 to slide towards the inner wall of the protective shell 4. The sliding of the latch 6 will release the limit with the storage battery 1, so that the charging head 3 can be inserted into the charging port of the tram for charging. After the charging head 3 is inserted into the charging port, the handlebar 10 will return to its original position. When the handlebar 10 returns to its original position, the latch 6 will contact the inner wall of the tram shell, which will strengthen the fixation of the charging head 3 with the tram shell. When the owner forgets that the tram is charging and drives away directly, it will pull the charging head 3 to move. The pulling of the charging head 3 will pull the cable 2. The cable 2 being pulled will slide on the inner wall of the protective shell 4. The sliding of the cable 2 will drive the sliding block 11 to move. The movement of the sliding block 11 will push the arc plate 8 to move. The movement of the arc plate 8 will drive the connecting rod 7 to move. The movement of the connecting rod 7 will drive the latch 6 to slide towards the inner wall of the protective shell 4. The sliding of the latch 6 will release the fixation with the tram. So when the tram drives away and the charging head 3 is pulled, the fixation between the charging head 3 and the tram will be quickly released, avoiding the cable 2 from being pulled. The cable 2 being pulled may be damaged or cause a short circuit due to the pulling, enabling the charging head 3 to quickly detach when subjected to a pulling force, which can prevent the cable 2 from being overstretched or damaged, thereby protecting the safety and service life of the cable 2. The movement of the sliding block 11 will release the limit on the sliding key 13, so the sliding key 13 will be pulled downward by the third spring. When the sliding key 13 moves downward, the sliding buckle 14 will contact the inner wall of the circular hole to limit the sliding key 13. The sliding key 13 being limited will limit the arc plate 8. The arc plate 8 being limited will limit the handlebar 10 from rotating back to its original position. When the handlebar 10 is fixed near the charging head 3, the exposed part of the handlebar 10 is less, and it is less likely to directly contact the ground, which helps to avoid the handlebar 10 directly contacting the hard ground due to falling, thereby reducing the probability of being impacted or worn.

[0026] Please refer to Figures 1-9 , on the basis of the above embodiment, in another embodiment of the present invention, wherein, an anti-collision device for protecting the outer wall of the charging head 3 and a rain-proof device for sealing and preventing rain for the charging head 3 are further provided on the outer wall of the charging head 3.

[0031] During the operation of this embodiment: The movement of the sliding block 11 will push the push rod 21 to move. The movement of the push rod 21 will contact the inclined surface of the sliding key 22. Then the push rod 21 will press the sliding key 22 to slide away from the fixed groove 23. Then the limit of the protection plate 24 will be released. Then the protection plate 24 will be driven by the second torsion spring to rotate towards the charging head 3.

[0032] When the rotating sleeve 25 rotates, the blocking of the sliding shift lever 31 will be released. Then, the sliding shift lever 31 is pulled by the sixth spring. When the sliding shift lever 31 moves, the limiting of the fixed plug 34 will be released. Then, the fixed plug 34 is pulled by the seventh spring to release the limit with the baffle 33. Then, the baffle 33 will be separated from the sealing plate 32. When the fixed plug 34 releases the limit with the fixed square plate 391, the sealing plate 32 will be driven by the fifth torsion spring to rotate towards the charging head 3. Then, the sealing plate 32 will wrap and seal the charging head 3, preventing the charging head 3 from falling to the ground when it is raining outside. If the charging head 3 is exposed to rainwater, moisture may enter the interior of the charging head 3, especially the electrical part, which may cause short circuits, corrosion or other electrical faults, affecting the normal operation of the charging head 3 and even potentially causing safety hazards such as fires. Wrapping and sealing can effectively block the intrusion of moisture and reduce these risks. When the sealing plate 32 seals the charging head 3, the sliding short rod 39 will slide towards the sliding pin 38. Then, the sliding short rod 39 will push the sliding pin 38 to move and release the limit on the rotating scraper 35. Then, the rotating scraper 35 will be driven by the fourth torsion spring to rotate. When the rotating scraper 35 rotates, it will scrape and clean the charging head 3. When the rotating scraper 35 moves, it will drive the rotating push rod 36 to move. When the rotating push rod 36 moves, it will push the round pin 37 to contact the inner wall of the fixed square plate 391. When the rotating scraper 35 rotates, it will scrape and clean the charging head 3. After the charging head 3 falls to the ground, dust, sand, oil or other debris may adhere to its surface. If not cleaned, these substances may enter the interface or circuit of the charging head 3, affecting the charging contact points and even potentially causing short circuits or other faults. Scraping and cleaning helps to remove surface debris and reduce the risk of these substances entering the interior.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
