[0002] With the popularity of electric vehicles, some existing parking lots are equipped with charging piles to replenish the power of electric vehicles in time. After being used by the car owners, the cables connected to the charging guns are often placed on the ground, where water and corrosive substances are likely to accumulate, causing corrosion to the cables and reducing the service life of the charging piles. The cables are dragged on the ground, which can easily cause wear on the protective shells on the cables, posing a safety hazard to others charging. Therefore, some charging piles that can automatically reel in the cables have gradually appeared.

[0003] For example, patent application number CN202221113395.2 discloses a new energy vehicle charging pile with an anti-winding structure, including a charging pile and a wire-receiving box installed on one side of the charging pile, a placement slot is provided on one side of the charging pile, a charging head is clamped inside the placement slot, a charging line is provided at the bottom of the charging head, a through hole is provided on one side of the wire-receiving box, one end of the charging line passes through the through hole and extends to the inside of the wire-receiving box, a reset assembly is provided inside the wire-receiving box, a limit plate is fixedly installed on the outside of the through hole, and the charging head includes a handle, a cap and a conductive slip ring. This new energy vehicle charging pile with an anti-winding structure not only has a wire-receiving box structure, which can automatically retract and release the charging line to prevent the charging line from being crushed and damaged, but also has a limit plate and a conductive slip ring, which can effectively prevent the charging line from rotating and winding, and has high practicality.

[0004] The prior art realizes the automatic retraction and anti-entanglement functions of the charging cable through structures such as the retracting box structure and the limiter, which has certain practicality, but still has certain shortcomings in the overall use process:

[0005] Existing charging piles are frequently used on rainy days or in humid environments. The charging cables will be exposed to humid environments for a long time, and the outside is easily sticky with dirt and a large amount of moisture. The existing technology lacks a method for removing dirt and moisture, and directly collects the dirt into the take-up box. Dust and dirt are easily accumulated inside the take-up box, causing the take-up to be not smooth. Moisture is easy to corrode the charging cable and various parts inside the box, seriously affecting the service life and cost. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, the utility model provides a charging pile with a winding structure. The utility model provides a plurality of annular inclined plates and scraper rings, so that most of the dirt and moisture sticking to the outside of the wire can be scraped off and cleaned multiple times during the winding process, and the setting of the colloid ring and the air chamber can ventilate and dry the charging wire and perform secondary cleaning, which can effectively prevent dust, dirt and moisture from entering the wire storage barrel, thereby improving the storage effect and service life.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a charging pile with a winding structure, comprising a charging pile and a wire storage barrel, a wire storage barrel is arranged on one end face of the charging pile, a barrel is rotatably arranged inside the wire storage barrel, an electric wire is wound outside the barrel, a wire passing barrel is arranged on the outer circular surface of the bottom of the wire storage barrel, one end of the electric wire extends through the center of the wire passing barrel and is connected to a charging gun, a plurality of downwardly inclined annular inclined plates are evenly arranged in a straight line direction inside the wire passing barrel, a scraper ring is arranged on the inclined end face of each annular inclined plate, a through-hole seat is arranged on the top of the wire passing barrel, a gas chamber for internally flowing dry gas is arranged inside the through-hole seat, and a plurality of air jets are arranged on the arc surface of the gas chamber close to the center of the circle.

[0008] Preferably, both end surfaces of the barrel are provided with limit plates, one side of the limit plate is provided with a driving motor on the end surface of the wire storage barrel, and the output end of the driving motor is connected and provided on the end surface of the barrel. The setting of the limit plate can improve the tightness of the wire after winding.

[0009] Preferably, a buffer cone pad is provided on the bottom end surface of the wire barrel, and the bottom end surface of the buffer cone pad cooperates with the charging gun. The provision of the buffer cone pad can reduce the occurrence of damage to the charging gun during the winding process.

[0026] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention. Embodiment 1:

[0027] refer to Figure 1-8 A charging pile with a winding structure includes a charging pile 10 and a wire storage drum 11. The wire storage drum 11 is arranged on an end surface of one side of the charging pile 10, and a material drum 15 is rotatably arranged inside the wire storage drum 11. An electric wire 17 is wound outside the material drum 15, and a wire barrel 19 is arranged on the outer circular surface of the bottom of the wire storage drum 11. One end of the electric wire 17 extends out through the center of the wire barrel 19 and is connected to a charging gun 13. A plurality of annular inclined plates 27 inclined downward are evenly arranged in a straight line direction in the wire barrel 19, and a scraper ring 28 is arranged on the inclined end surface of each annular inclined plate 27. A through hole seat 21 is arranged on the top of the wire barrel 19, and a gas chamber 22 for internal flowing dry gas is arranged in the through hole seat 21, and a plurality of jet ports 23 are arranged on the arc surface of the gas chamber 22 near the center of the circle.

[0028] Specifically, the charging pile 10 is a prior art, including an operation panel, a charging module, a cabinet door, a heat dissipation structure, etc., which are not specifically described herein. The barrel 15 inside the wire storage barrel 11 completes the wire collection or wire release processing of the wire 17 by rotating clockwise or counterclockwise. The wire barrel 19 is arranged on the outer cylindrical surface of the bottom of the wire storage barrel 11, and the middle part of the whole is hollow, so that one end of the wire 17 can extend to the outside of the wire storage barrel 11 through the wire barrel 19. The end of the wire 17 extending to the outside of the wire storage barrel 11 is connected to the charging gun 13. The wire 17 and the charging gun 13 are both prior art. The specific material and shape are not described in detail herein. The illustration is for reference only. The user can pull the charging gun 13 to pull the wire 17 outward. During the pulling-out process, the barrel 15 will rotate, so that the wire 17 can be released smoothly, so that charging can proceed smoothly.

[0029] When charging is completed, the barrel 15 will rotate, thereby driving the wire 17 wound on the outside to be wound up. During this process, the outer cylindrical surface of the wire 17 will contact the outer cylindrical surfaces of multiple scraper rings 28. The scraper rings 28 are generally annular in shape, and the inner arc surface fits the outer cylindrical surface of the wire 17. During the winding process of the wire 17, the multiple scraper rings 28 will scrape off the dirt and moisture on the outside of the wire 17. The outside of the scraper ring 28 is connected and fixed by an annular inclined plate 27. The multiple annular inclined plates 27 are arranged tilted downward and are made of elastic material. During the scraping process, when the scraper ring 28 is displaced to a certain extent due to the change in contact friction caused by the movement of the wire 17, the annular inclined plate 27 can absorb the vibration to ensure the stability of the scraper ring 28 when scraping;

[0030] When the outer cylindrical surface of the wire 17 moves to the top of the wire barrel 19, it will pass through the through-hole seat 21. The through-hole seat 21 is hollow in the middle part like the wire barrel 19, so that the wire 17 can move smoothly. The air chamber 22 is arranged in the middle part of the through-hole seat 21. When the wire 17 moves to the position of the air chamber 22, dry gas with a certain temperature can flow inside the air chamber 22, and then it can be sprayed on the outer cylindrical surface of the wire 17 through the air jet 23, so that the outer cylindrical surface of the wire 17 can be dried, so that there is no moisture on the outside of the wire 17 after winding, thereby improving the storage quality and the service life.

[0031] Furthermore, the other end of the wire 17 is connected to the inside of the charging pile 10 .

[0032] Specifically, the other end of the wire 17 is connected to the inside of the charging pile 10 to complete the power supply processing, and will not be rolled when the barrel 15 rotates. The specific anti-rolling structure and technology are all existing technologies and will not be elaborated in this article.

[0033] refer to Figure 8 A heating seat 12 is arranged on one end surface of the wire storage tube 11, a heater 31 is arranged in the heating seat 12, the heating seat 12 is connected to the air chamber 22 through a hose, an air inlet cylinder 14 is arranged outside the heating seat 12, and a pump 32 is arranged in the air inlet cylinder 14.

[0034] Specifically, a dust-proof mesh is provided on the outside of the air inlet 14, and a pump 32 arranged inside the air inlet 14 can draw external gas into the air inlet 14 and discharge the gas into the heating seat 12. The heater 31 inside the heating seat 12 can heat and dry the gas. The heated and dried gas can flow into the gas warehouse 22 through a hose connecting the heating seat 12 and the gas warehouse 22, so that the gas warehouse 22 can dry the outside of the wire 17. In this relationship, the technology of pumping gas flow by the pump 32 and the drying and heating technology of the heater 31 are both existing technologies, and the specific working principles will not be elaborated in this article.

[0035] refer to Figure 5 A colloid ring 24 is provided at the top of the through hole seat 21 above the air chamber 22 , and a conical opening 26 is provided at the center of the bottom of the through hole seat 21 below the colloid ring 24 .

[0036] Specifically, the colloid ring 24 is made of sponge material, has good water absorption and air permeability effects, and is provided with a plurality of stripes for scraping water on the inner wall. It is arranged above the air jet 23 to perform secondary dehumidification and scraping treatment on the dried wire 17 to ensure the dryness of the wire 17 during storage; the conical mouth 26 is arranged below the air jet 23, and is generally in a conical shape that is narrow at the top and wide at the bottom. The purpose of this arrangement is that the dry gas ejected through the air jet 23 can diffuse downward through the conical mouth 26 to flow into the inside of the wire barrel 19, thereby forming a flow of dry gas inside the wire barrel 19, so that the inside of the wire barrel 19 can also be ventilated and dried, thereby improving the cleaning effect.

[0037] refer to Figure 5 A second connecting hole 25 is provided on the bottom inclined surface of each annular inclined plate 27 , and a plurality of first connecting holes 20 are provided on the bottom outer circumferential surface of the wire barrel 19 below the plurality of annular inclined plates 27 .

[0038] Specifically, the annular inclined plate 27 is tilted downward so that the scraped dirt and moisture will accumulate at the position adjacent to the scraper ring 28 and the wire 17. The second connecting hole 25 is arranged above the scraper ring 28. When the dirt accumulates to the height of the second connecting hole 25, it can be discharged downward. In this article, the specific shape of the second connecting hole 25 and the discharge quantity are not restricted. The setting of the second connecting hole 25 can ensure the smooth discharge of dirt. The first connecting hole 20 is set at the bottom of the wire barrel 19. On the one hand, it is convenient for gas flow, and on the other hand, it allows the dirt to be discharged smoothly.

[0039] refer to Figure 4 A limit plate 18 is disposed on both side end surfaces of the barrel 15 , and a drive motor 16 is disposed on one side of the limit plate 18 on the end surface of the wire storage barrel 11 , and an output end of the drive motor 16 is connected to the end surface of the barrel 15 .

[0040] Specifically, the adjacent end surfaces of the two limit plates 18 are provided with a plurality of anti-slip grooves, which can perform anti-slip limiting treatment on both sides of the wire 17 wound by the barrel 15, so that the wire 17 can be guaranteed to be tight; the drive motor 16 is a prior art and will not be elaborated in this article. The output end of the drive motor 16 can drive the barrel 15 to rotate, thereby completing the winding and unwinding of the wire 17.

[0041] refer to Figure 5 A buffer cone pad 30 is provided on the bottom end surface of the wire barrel 19, and the bottom end surface of the buffer cone pad 30 cooperates with the charging gun 13.

[0042] Specifically, the center of the end face of the buffer cone pad 30 is in the shape of an inwardly inclined cone hole, and a plurality of anti-slip grooves are arranged on the inner wall of the cone hole. The buffer cone pad 30 is made of elastic buffer material. When all the wires 17 are rolled up into the wire storage barrel 11, the charging gun 13 will be driven by the wires 17 to move upward until the top of the charging gun 13 abuts against the end face of the buffer cone pad 30 and stops moving. The buffer cone pad 30 can perform vibration absorption during the abutment process, so that the charging gun 13 will not be damaged due to rapid abutment, thereby improving the service life. Embodiment 2:

[0043] On the basis of or different from the first embodiment, reference Figure 5 A plurality of elastic support plates 29 are connected between each annular inclined plate 27 and the inner wall of the wire barrel 19 .

[0044] Specifically, a plurality of elastic support plates 29 can elastically support the annular inclined plate 27, so that the stability of the annular inclined plate 27 is improved, and excessive deformation will not occur due to large changes in friction between the scraper ring 28 and the wire 17, thereby ensuring the scraping effect.
