When the charging pile is in use, when there are obstacles in front of the new energy vehicle charging pile and in the direction of movement, the new energy vehicle to be charged can be charged conveniently and timely. When the charging pile is in use, the charging cable cannot be reasonably stored, and the charging cable is stored manually. Since the charging cable is heavy, it is not convenient for personnel to store it manually. If the charging cable is exposed to the external environment for a long time, especially the charging cable scattered on the ground, it is easy to be stepped on, resulting in damage to the charging cable.

A motor 22 is fixedly installed on the surface of the wire storage box 21 away from the charging pile body 1. A motor waterproof box is fixedly provided at a position corresponding to the motor 22 on the wire storage box 21 to protect the motor 22 and prevent rain from falling directly on the motor 22. The wire storage box 21 is provided with a hole through which the output shaft of the power supply motor 22 passes. The output shaft of the motor 22 near the charging pile body 1 is fixedly connected to a winding shaft 23. The portion of the charging line 14 located inside the wire storage box 21 is wound on the outer ring surface of the winding shaft 23. The motor 22 is controlled by the controller on the charging gun 13, and can control the forward and reverse rotation of the output shaft of the motor 22 and the opening and closing of the motor 22. A cable tray 24 is fixedly connected inside the wire storage box 21. The cable tray 24 consists of two fixedly connected annular disks. The portion of the charging line 14 below that is not wound on the outer ring surface of the winding shaft 23 is located outside the cable tray 24. The cable tray 24 and the winding shaft 23 are coaxially arranged, and the cable tray 24 is located on the periphery of the winding shaft 23. The winding shaft 23 passes through the wire storage box 21 and is fixedly connected to a transverse axis 25 at one end. The transverse axis 25 passes through the wire storage box 21 and extends to the outside of the wire storage box 21 and is rotatably connected to the outer wall of the charging pile body 1. A concave plate 27 is fixedly connected to the outer wall of the wire storage box 21 on the side close to the charging pile body 1, and a rotating rod 28 is rotatably connected to the middle part of the concave plate 27. An increasing speed transmission component is provided on the side of the rotating rod 28 close to the horizontal axis 25, and the horizontal axis 25 drives the rotating rod 28 to rotate through the increasing speed transmission component. Specifically, the increasing speed transmission component includes an extension rod coaxially fixedly connected to the rotating rod 28, and the extension rod is located on the side of the rotating rod 28 close to the horizontal axis 25. A torsion spring pawl 216 is rotatably connected to the surface of one end of the extension rod away from the rotating rod 28. The torsion spring pawl 216 includes a shaft body rotatably connected to the extension rod and a pawl fixedly connected to the shaft body. A torsion spring is connected to the portion where the torsion spring pawl 216 is rotatably connected to the extension rod, and one end of the torsion spring is fixedly connected to the extension rod, and the other end is fixedly connected to the rotating shaft in the torsion spring pawl 216.

[0022] like Figure 5 , Figure 6As shown, a reciprocating groove 29 is provided on the outer annular surface of the rotating rod 28, an extension plate 271 is fixedly connected to the outer wall of the concave plate 27 on one side close to the rotating rod 28, and a collar 210 is sleeved on the rotating rod 28, and the collar 210 is initially located at one end of the rotating rod 28 close to the extension plate 271. A hemispherical block 211 is provided on the inner annular surface of the collar 210, and the hemispherical block 211 slides inside the reciprocating groove 29, and the groove surface of the reciprocating groove 29 and the outer surface of the hemispherical block 211 are both smooth surfaces to ensure the smooth sliding displacement of the hemispherical block 211 in the reciprocating groove 29. A belt plate disk 213 is fixedly connected to the outer ring surface of the ring 210 on the side away from the extension plate 271. The belt plate disk 213 includes a plate body fixedly connected to the upper and lower sides of the ring 210 and a disk fixedly connected to the end of the plate body away from the ring 210. The two plates in the belt plate disk 213 are fixedly connected to a rectangular block 212 at one end close to the ring 210. The upper and lower sides of the concave plate 27 are provided with through grooves for the horizontal sliding displacement of the rectangular block 212. A bent rod 214 is fixedly connected to the top of the disk in the belt plate disk 213. A conical cylinder 215 is fixedly connected to the end of the bent rod 214 away from the disk. The end of the charging line 14 close to the wire storage box 21 passes through the center of the conical cylinder 215. A circular scraper is provided at the end of the conical cylinder 215 away from the wire storage box 21. The circular scraper is in contact with the outer surface of the charging line 14, and the blade of the circular scraper is not sharp and is only used to scrape impurities on the outer wall of the charging line 14. The end of the extension plate 271 away from the concave plate 27 is rotatably connected to a small bevel gear 217, and a ratchet plate 218 is fixedly connected to the surface of the small bevel gear 217 on one side close to the torsion spring pawl 216. Ratchet teeth are evenly arranged on the inner ring surface of the ratchet plate 218. Initially, the torsion spring pawl 216 meshes with the ratchet teeth on the inner ring surface of the ratchet plate 218. A large bevel gear 219 is fixedly connected to the position of the horizontal shaft 25 corresponding to the small bevel gear 217, and the large bevel gear 219 and the small bevel gear 217 mesh with each other.

[0023] Furthermore, if Figure 2 , Figure 4 As shown, a fixed box 2101 is fixedly connected to the interior of the wire storage box 21, and the fixed box 2101 is located directly below the wire bundle reel 24. A moving box 2102 is inserted into the interior of the fixed box 2101, and a number of solid granular desiccants are placed inside the moving box 2102. Strip holes are evenly arranged on the fixed box 2101 and the moving box 2102, and one end of the moving box 2102 extends to the outside of the wire storage box 21. Specifically, one end of the moving box 2102 extending to the outside of the wire storage box 21 is provided with a handle for easy grasping by hand.

[0024] During use: When the user charges the new energy vehicle, the charging gun 13 can be manually removed from the gun slot 11 and the protective cover 12, and the motor 22 can be started by the control switch on the charging gun 13, so that the output shaft of the motor 22 drives the winding shaft 23 to rotate slowly counterclockwise, thereby releasing the charging line 14 wound on the outer ring surface of the winding shaft 23, and in the process of the user holding the charging gun 13 and gradually approaching the charging port of the car, the released charging line 14 is gradually pulled out from the inside of the wire storage box 21.

[0025] In order to remove dust and other impurities attached to the outer wall of the charging cable 14, when the user finishes charging, he can hold the charging gun 13 and put it back into the gun slot 11. Then, the controller starts the motor 22, causing its output shaft to rotate clockwise, driving the winding shaft 23 to rotate synchronously, and then the winding shaft 23 drives the horizontal shaft 25 to rotate synchronously. As the winding shaft 23 rotates clockwise, the pulled charging cable 14 will be automatically retracted into the wire storage box 21 and automatically wound back on the outer ring surface of the winding shaft 23, thereby realizing the automatic reeling of the charging cable 14. Therefore, by cooperating with the wire storage box 21 and the winding shaft 23 and other components, most of the charging wires 14 are initially wound on the winding shaft 23 and are inside the wire storage box 21, so that the wire storage box 21 protects the charging wires 14 and also prevents the charging wires 14 from being scattered on the ground when not in use, thereby effectively avoiding the situation where the charging wires 14 are stepped on, thereby preventing the charging wires 14 from being damaged and ensuring the safety of the charging wires 14. At the same time, the motor 22 drives the winding shaft 23 to rotate to realize the automatic winding of the charging wire 14, and there is no need to manually wind the charging wire 14 during the process, thereby reducing the burden of user operation.

[0026] As the horizontal shaft 25 rotates clockwise, the large bevel gear 219 is also driven to rotate synchronously, and the small bevel gear 217 meshing with it is driven to rotate counterclockwise through the large bevel gear 219. As the small bevel gear 217 rotates counterclockwise, the extension rod and the rotating rod 28 are driven to rotate synchronously through the ratchet plate 218 and the torsion spring pawl 216. Since the radius of the large bevel gear 219 is larger than the radius of the small bevel gear 217, the rotation of the large bevel gear 219 can drive the small bevel gear 217, the rotating rod 28 and other components to rotate multiple circles. As the rotating rod 28 rotates counterclockwise, the reciprocating groove 29 is driven to rotate and squeeze with the hemispherical block 211, so that the ring 210, the plate plate 213, the bent rod 214, and the conical cylinder 215 are driven to reciprocate horizontal displacement under the cooperation of the rectangular block 212 and the through groove. Therefore, when the charging cable 14 is being retracted, the conical cylinder 215 provided on the winding path of the charging cable 14 is used to reciprocate horizontally along the outer wall of the charging cable 14 to scrape off the dust and impurities attached to the outer wall of the charging cable 14. Under the action of the circular scraper, the stubborn impurities attached to the outer wall of the charging cable 14 or the ice layer condensed on the outer wall of the charging cable 14 in winter can be further effectively removed. In this way, after each use of the charging cable 14, the impurities attached to the outer wall of the charging cable 14 can be automatically removed to prevent some impurities from corroding the charging cable 14, thereby ensuring the safety of the use of the charging cable 14 and improving its service life.

[0027] After the charging cable 14 is retracted into the reel 23 and placed inside the wire storage box 21, the desiccant placed inside the movable box 2102 disposed inside the wire storage box 21 effectively absorbs moisture inside the wire storage box 21, thereby preventing water vapor from forming on the surface of the charging cable 14 inside the wire storage box 21, thereby ensuring the dryness of the charging cable 14 inside the wire storage box 21. In addition, when the staff needs to replace the desiccant inside the movable box 2102, the movable box 2102 is pulled out horizontally from the fixed box 2101 by holding the handle, so that the movable box 2102 is horizontally moved out of the wire storage box 21, and then new desiccant is placed inside the movable box 2102. Through the fixed box 2101 and the movable box 2102, the staff can simply and conveniently replace the desiccant, thereby improving the convenience of replacing the desiccant inside the movable box 2102.

[0028] In addition, when the winding shaft 23 drives the horizontal shaft 25 to rotate counterclockwise during the above process, the large bevel gear 219 will not drive the small bevel gear 217 to rotate clockwise through the ratchet plate 218 and the torsion spring pawl 216, thereby avoiding the horizontal movement of the conical tube 215 affecting the stability of the hand-held charging gun 13 when the user pulls out the charging cable 14 from the cable box 21.

[0029] Embodiment 2: Figure 7 , Figure 8As shown, the new energy vehicle charging pile also includes a matching component arranged on the side of the wire box 21 close to the conical cylinder 215, and the matching component includes a notch 31 opened on the outer surface of the wire box 21 close to the conical cylinder 215. A guide plate 32 is fixedly connected below the position of the wire box 21 corresponding to the notch 31. The guide plate 32 is composed of two fixedly connected plate bodies, wherein a circular hole for the charging line 14 to pass through is opened on the upper plate body, the upper plate body is vertically arranged, and the lower plate body is inclined, and is inclined in the direction away from the side of the wire box 21. The lower end of the guide plate 32 extends to the outside of the wire storage box 21. The side surface of the guide plate 32 away from the wire storage box 21 is provided with a guide groove. The side surface of the conical cylinder 215 close to the notch 31 is fixedly connected with a matching disk 33. The side surface of the matching disk 33 away from the conical cylinder 215 is bonded with a sponge cover 34. The sponge cover 34 initially fits with the plate body in the upper middle of the guide plate 32, and the sponge cover 34 is in a compressed state at this time. The sponge cover 34 is composed of two semicircular rings, which form a complete ring, and the center of the ring and the center of the matching disk 33 can be passed through by the charging line 14. The sponge cover 34 is attached to the matching disk 33 by Velcro. When the user needs to replace the sponge cover 34, the user can operate by hand at the notch 31 to remove the sponge cover 34 from the matching disk 33, and then bond the new sponge cover 34 back again, thereby improving the practicality and convenience of the sponge cover 34.

[0030] When in use: In order to reduce the rainwater on the outer wall of the charging cable 14, and prevent the rainwater from entering the inside of the wire storage box 21. When the charging cable 14 is retracted, after passing through the matching plate 33 and the sponge cover 34, the rainwater attached to the outer wall of the charging cable 14 can be automatically absorbed by the adsorption of the sponge cover 34. And in the process of the reciprocating horizontal movement of the conical cylinder 215, when the conical cylinder 215 is horizontally displaced in the direction away from the charging pile body 1, the sponge cover 34 returns to its natural state, and when the conical cylinder 215 is horizontally displaced in the direction close to the charging pile body 1, the sponge cover 34 will be squeezed, so that the water adsorbed by the sponge cover 34 is automatically squeezed out, and the squeezed rainwater will automatically flow downward along the guide grooves on the upper plate body and the lower plate body in the guide plate 32. Therefore, the sponge cover 34 can automatically absorb rainwater attached to the outer wall of the charging cable 14 when the charging cable 14 is retracted, thereby preventing rainwater from entering the interior of the wire storage box 21, causing excessive humidity in the wire storage box 21, and affecting the storage dryness of the charging cable 14. At the same time, the rainwater absorbed by the sponge cover 34 can be discharged in time by squeezing, thereby ensuring that the sponge cover 34 can continue to absorb water.

[0031] Embodiment 3: Fig. 9 , Fig.10As shown, the above-mentioned new energy vehicle charging pile also includes a follow-up processing mechanism arranged on the side of the charging pile body 1 close to the horizontal axis 25, and the follow-up processing mechanism includes a large gear 41 fixedly connected to the outer ring surface of one end of the horizontal axis 25 close to the charging pile body 1, and the surface of the charging pile body 1 close to the horizontal axis 25 is rotatably connected with a small gear 42, and the small gear 42 is located above the large gear 41 and meshes with the large gear 41. A placement cabin 43 is provided on the side of the charging pile body 1 close to the charging gun 13, and a piston cylinder 44 is fixedly connected to the cabin wall inside the placement cabin 43, and a reciprocating screw rod 45 is rotatably connected to the inner center of the piston cylinder 44, and a piston disc 46 is threadedly connected to the reciprocating screw rod 45, and the piston disc 46 is initially located on the side of the piston cylinder 44 away from the charging pile body 1. The end of the reciprocating screw rod 45 away from the charging pile body 1 extends to the outside of the piston cylinder 44. The end of the reciprocating screw rod 45 located outside the piston cylinder 44 is connected to the pinion 42 by a synchronous component 47. The synchronous component 47 includes two synchronous wheels and a synchronous belt connected between the two synchronous wheels. One synchronous wheel is fixed to the pinion 42, and the other synchronous wheel is fixed to the end of the reciprocating screw rod 45 located outside the piston cylinder 44. The diameter of the large gear 41 is much larger than the diameter of the small gear 42, so that the small gear 42 can be driven to rotate several more times by the rotation of the large gear 41, and then the synchronous belt box synchronous wheel can be used to drive the reciprocating screw rod 45 to rotate several more times to improve the effectiveness of negative pressure dust suction. The end of the piston cylinder 44 away from the charging pile body 1 is fixedly connected to a connecting pipe 48 and a discharge pipe 49. The connecting pipe 48 is located above the discharge pipe 49. The connecting pipe 48 and the discharge pipe 49 are connected to the piston cylinder 44. A one-way valve is installed at the part where the connecting pipe 48 and the discharge pipe 49 are connected to the piston cylinder 44. One end of the connecting tube 48 away from the piston cylinder 44 passes through the protective cover 12 and extends to the inside of the gun receiving groove 11. One end of the connecting tube 48 located inside the gun receiving groove 11 is fixedly connected to a suction tube 410. The suction tube 410 is provided with a trumpet-shaped suction nozzle at one end close to the charging pile body 1. The trumpet-shaped suction nozzle is conducive to airflow concentration and convergence, and when the charging gun 13 is placed inside the gun receiving groove 11, the charging insertion port of the charging gun 13 corresponds exactly to the suction nozzle.

[0032] When in use: When the reel 23 reels and releases the charging cable 14, the horizontal axis 25 is driven to rotate clockwise and counterclockwise, and the large gear 41 is also driven to rotate synchronously, and then the small gear 42 is driven to rotate in the opposite direction through the large gear 41. With the reverse rotation of the small gear 42, the two synchronous wheels and the synchronous belt in the synchronous component 47 are cooperated to drive the reciprocating screw 45 to rotate synchronously. As the reciprocating screw 45 rotates, it drives the piston disc 46 to reciprocate horizontally inside the piston cylinder 44. When the piston disc 46 is horizontally displaced toward the side away from the connecting pipe 48, the one-way valve on the connecting part of the connecting pipe 48 and the piston cylinder 44 is opened, and the one-way valve on the connecting part of the discharge pipe 49 and the piston cylinder 44 is closed, so that negative pressure is formed at the suction nozzle through the connecting pipe 48 and the suction pipe 410. When the charging gun 13 is put back into the gun slot 11, the negative pressure at the suction nozzle is used to automatically suck the dust and other impurities attached to the charging socket of the charging gun 13 into the piston cylinder 44. When the piston disc 46 is displaced horizontally toward the direction close to the connecting pipe 48, the one-way valve on the connecting portion between the connecting pipe 48 and the piston cylinder 44 is closed, and the one-way valve on the connecting portion between the discharge pipe 49 and the piston cylinder 44 is opened, so that the dust and impurities sucked into the piston cylinder 44 are discharged from the discharge pipe 49. The end of the discharge pipe 49 away from the connecting pipe 48 can be connected to an existing dust collecting bag to collect dust and impurities in a centralized manner to prevent dust from flying around. Therefore, by providing the suction pipe 410 and the suction nozzle inside the gun placement slot 11, the charging interface of the charging gun 13 can be adsorbed during the process of taking out and putting back the charging gun 13, and the dust and impurities attached to the charging interface of the charging gun 13 can be removed, thereby preventing dust and impurities from affecting the safety of charging the charging gun 13.
