Description

Technical Field

[0001] The utility model belongs to the technical field of charging piles, and in particular relates to a novel charging pile. Background Art

[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 release and anti-entanglement functions of the charging cable through structures such as a wire-reel box structure and a limit plate, and has certain practicality. However, there are still certain deficiencies in the overall use process: first, the prior art lacks a structure that can automatically limit and fix the wire drum formed by winding the charging cable during the winding process, causing the charging cable to loosen and spread during the winding and release process, resulting in poor winding and release; secondly, the charging cable is prone to moisture being brought into the winding box during the winding process. A large amount of charging cable with water is wound into a roll, which is prone to corrosion and mildew. The prior art lacks a structure for drying the wound charging cable. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a new charging pile. The utility model uses the arrangement of sliding blocks, springs, and limit plates to allow the wires to be elastically limited at multiple points during the process of winding and releasing the wires, thereby preventing the wires from loosening and falling off. The arrangement of the hollow shaft and the ventilator allows the dry gas to be dispersed from the inside of the wound wires to the outside, so that the wires and the wire storage barrel can be effectively dried at all locations, effectively improving the storage effect and the user experience.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of charging pile, including a charging pile and a wire storage barrel, a wire storage barrel is arranged on one end face of the charging pile, a hollow shaft is rotatably arranged inside the wire storage barrel, a plurality of vents are arranged on the outer circumference of the hollow shaft, a limit plate is arranged on both end faces of the hollow shaft, a plurality of rough panels are arranged on the adjacent end faces of the two limit plates, a limit plate is slidably arranged between the two rough panels, a plurality of convex strips are arranged on the bottom end face of each limit plate, wires are wound on the outer circumference of the hollow shaft between the plurality of limit plates, a connecting pipe port is arranged on the end face of the wire storage barrel on one side of the hollow shaft, and a ventilator is arranged outside the connecting pipe port. The setting of the limit plate improves the tightening effect of the wires.

[0007] Preferably, one end of the electric wire is connected and arranged in the charging pile, and the other end of the electric wire extends out of the outer cylindrical surface of the wire storage barrel and is connected and arranged with a charging gun.

The setting of the sliding block and the spring enables the limit plate to perform elastic movement and limit processing according to the change of the diameter of the wire barrel.

[0009] Preferably, a second drive motor is arranged in the ventilation tube, and a rotating fan wheel is connected to the output end of the second drive motor. The arrangement of the rotating fan wheel enables external air to smoothly enter the hollow shaft.

[0010] Preferably, a heating plate is provided in the connecting pipe opening, and the arrangement of the heating plate enables the gas to be fully heated and dried.

[0011] Preferably, elastic pads are provided on both sides of the bottom end surface of each limiting plate. The provision of the elastic pads can improve the limiting and fixing effect of the wires.

[0012] Preferably, a first drive motor is arranged on one end surface of the wire storage drum, and an output end of the first drive motor is connected to the end surface of the hollow shaft.

[0023] 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:

[0024] refer to Figure 1-7A new type of charging pile includes a charging pile 51 and a wire storage barrel 52. The wire storage barrel 52 is arranged on one end surface of the charging pile 51, a hollow shaft 56 is rotatably arranged in the wire storage barrel 52, a plurality of vent holes 58 are arranged on the outer circumferential surface of the hollow shaft 56, and a limit plate 57 is arranged on both side end surfaces of the hollow shaft 56. A plurality of rough panels 70 are arranged on the adjacent end surfaces of the two limit plates 57, and a limit plate 68 is slidably arranged between the two rough panels 70, and a plurality of convex strips 69 are arranged on the bottom end surface of each limit plate 68. Wires 54 are wound on the outer circumferential surface of the hollow shaft 56 between the plurality of limit plates 68, a connecting pipe port 63 is arranged on one side of the hollow shaft 56 on the end surface of the wire storage barrel 52, and a ventilator 59 is arranged outside the connecting pipe port 63.

[0025] Specifically, the charging pile 51 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 hollow shaft 56 inside the wire storage barrel 52 completes the wire collection or wire release processing of the wire 54 by rotating clockwise or counterclockwise. The wire 54 is a prior art, and the specific material and shape are not described in detail herein, and the illustration is only for reference;

[0026] The limiting plates 57 arranged on the end faces of both sides of the hollow shaft 56 can limit and fix the two ends of the wire 54 wound into a bobbin. The outer end faces of the multiple rough panels 70 on the end faces of the limiting plates 57 are all roughened, which can increase the limiting friction between the wire 54 and reduce the occurrence of the wire 54 spreading out. The multiple limiting plates 68 arranged between the rough panels 70 are evenly distributed in the circumferential direction. During the process of winding or unwinding the wire 54, they will always press on the outer circumferential surface of the bobbin formed by the wire 54, so that the bobbin can be limited. The multiple convex strips 69 on the end faces of the limiting plates 68 can better fit into the angle formed when the wire 54 is wound, which can effectively improve the anti-scattering and anti-slip treatment of the wire 54 and improve the fastening effect.

[0027] The middle part of the hollow shaft 56 is hollow, and a plurality of ventilation holes 58 connected with the hole in the middle are arranged on the outer circumferential surface. When the wire 54 is wound on the outside of the hollow shaft 56, the ventilation tube 59 can inject dry gas into the connecting pipe mouth 63, and then discharge it into the hole in the middle of the hollow shaft 56. The gas entering the hole in the middle of the hollow shaft 56 can be dispersed to the outer circumferential surface of the hollow shaft 56 through the plurality of ventilation holes 58, so that the wire 54 wound on the outside of the hollow shaft 56 can be ventilated and dried, the moisture on the outside of the wire 54 can be removed, and the storage life of the wire 54 can be improved.

[0028] refer to Figure 3 One end of the wire 54 is connected to the charging pile 51, and the other end of the wire 54 extends out of the outer surface of the wire storage tube 52 and is connected to the charging gun 53.

[0029] Specifically, the other end of the wire 54 is connected to the inside of the charging pile 51 to complete the power supply processing. It will not be rolled up when the hollow shaft 56 rotates. The specific anti-rolling structure and technology are all existing technologies and will not be elaborated in this article. One end of the wire 54 can extend to the outside of the wire storage barrel 52. The end of the wire 54 extending to the outside of the wire storage barrel 52 is connected to a charging gun 53. The charging gun 53 is existing technology. The specific material and shape are not elaborated in this article. The illustration is for reference only. The user can pull the charging gun 53 to pull the wire 54 outward. During the pulling-out process, the hollow shaft 56 will rotate, so that the wire 54 can be released smoothly, so that charging can proceed smoothly.

[0030] refer to Figure 4-5 Each limiting plate 68 is provided with a rectangular opening 67 on both sides of the end surface of the limiting plate 57, a sliding inner tube 64 is provided on one side of the rectangular opening 67, a sliding block 66 is slidably provided in the sliding inner tube 64, both ends of the limiting plate 68 are connected to the sliding block 66, and a spring 65 is connected between the bottom of the sliding block 66 and the bottom of the sliding inner tube 64.

[0031] Specifically, the sliding inner tube 64 and the rectangular opening 67 are evenly arranged along the circumferential direction inside and outside the end surface of the limit plate 57. The length of the rectangular opening 67 is the sliding stroke of the limit plate 68. The specific length is set according to actual needs and is not limited in this scheme. The sliding block 66 can slide inside the sliding inner tube 64 so that the limit plate 68 can move up and down. The setting of the spring 65 at the bottom of the sliding block 66 makes the sliding block 66 have an elastic tensioning force, so that when the diameter of the wire barrel formed by the electric wire 54 changes, the limit plate 68 can form elastic pressure through the spring 65 during the movement, so that the wire barrel can be stably compressed.

[0032] refer to Figure 3 A first drive motor 55 is disposed on one end surface of the wire storage drum 52 , and an output end of the first drive motor 55 is connected to an end surface of a hollow shaft 56 .

[0033] Specifically, the first driving motor 55 is a prior art, which will not be elaborated in detail herein. The output end of the first driving motor 55 can drive the hollow shaft 56 to rotate, thereby completing the winding and unwinding of the electric wire 54 .

[0034] refer to Figure 4 A second driving motor 60 is arranged in the ventilation tube 59 , and a rotating fan wheel 62 is connected to the output end of the second driving motor 60 .

[0035] Specifically, when gas flow is required inside the hollow shaft 56, the output end of the second drive motor 60 can drive the rotating fan wheel 62 to rotate, thereby driving the external gas to flow into the hollow shaft 56. In this solution, the shape of the rotating fan wheel 62 is not restricted, and fan blades with better boosting effects are preferentially selected.

[0036] refer to Figure 4 A heating plate 61 is arranged in the connecting pipe opening 63 .

[0037] Specifically, the heating disk 61 can heat and dry the gas flowing through the connecting pipe port 63, so that the gas flowing into the hollow shaft 56 is in a dry state. Embodiment 2:

[0038] On the basis of or different from the first embodiment, reference Figure 7 Elastic pads 71 ​​are provided on both sides of the bottom end surface of each limiting plate 68 .

[0039] Specifically, the elastic pad 71 is made of elastic material and has a roughened end surface. When the convex strip 69 is embedded in the angle formed by the winding of the wire 54, the elastic pad 71 will also be pressed and contacted with the outside of the wire 54, thereby forming a secondary limit and anti-slip treatment on the outside of the wire 54 and improving the stability of the wire reel.

[0040] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction.
