Description

Technical Field

[0001] The utility model belongs to the technical field of charging piles, and in particular relates to a charging pile with a winding structure. 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 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] First, the diameter of the charging cable is relatively thick, and it has a certain rebound deformation effect. When it is rotated and wound into a wire drum, the contact tightness between the wires is insufficient, and it is easy to loosen and spread, affecting the normal efficiency of winding and releasing the wires. The prior art lacks a better limiting structure; secondly, the interior of the wire box lacks a ventilation and drying structure, and the interior is humid and stuffy, affecting the storage of the charging cable. 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 rotating roller and a ball head lever so that the outer part of the wire can be elastically limited and moved at multiple points during the winding and unwinding process, which can prevent the wire from loosening and falling off and from being entangled and knotted. The arrangement of the air cylinder and the air jet seat allows dry gas to flow inside the wire storage barrel and between the wires, which can effectively reduce the humidity inside the wire storage barrel and improve the service life and safety of use.

[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 drum, wherein a wire storage drum is arranged on one end surface of the charging pile, a barrel is rotatably arranged inside the wire storage drum, a wire is wound on the outer circumferential surface of the barrel, one end of the wire extends out of the outer circumferential surface of the wire storage drum and is connected to a charging gun, a plurality of connecting frames are evenly slidably arranged along the circumferential direction on the outside of the barrel, rotating rollers are rotatably arranged on both sides of each connecting frame, a plurality of ball head levers are arranged between two rotating rollers, an air jet seat is arranged on the end surface of the connecting frame, and a heating plate is arranged inside the air jet seat. The arrangement of the rotating roller and the ball head lever can effectively prevent the occurrence of scattered and tangled wires.

[0008] Preferably, a plurality of push cylinders are evenly arranged on the outer circumferential surface of the wire storage barrel along the circumferential direction, and the output ends of the push cylinders are connected to the end surface of the connecting frame. The arrangement of the push cylinders allows the moving distance and the limiting strength of the connecting frame to be adjusted.

[0009] Preferably, a wind tube is arranged on the outer circumference of the wire storage cylinder above the air jet seat, a second driving motor is fixedly arranged in the wind tube, a rotating fan wheel is connected to the output end of the second driving motor, and the wind tube is connected to the air jet seat through a hose. The arrangement of the wind tube allows the dry gas to flow smoothly.

[0010] Preferably, a wire passing seat is arranged on the outer circumference of the wire storage barrel outside the wire. The arrangement of the wire passing seat enables the wire to be smoothly retracted and released.

[0011] Preferably, a first drive motor is arranged on one end surface of the wire storage barrel, and an output end of the first drive motor is connected to the end surface of the barrel. The arrangement of the first drive motor enables the barrel to rotate smoothly.

[0012] Preferably, a plurality of convex strips are arranged on the outer circumferential surface of each rotating roller. The arrangement of the convex strips improves the limiting and fixing effect.

[0013] Preferably, a plurality of positioners are arranged on the upper end surface of the jet seat, and the arrangement of the positioners enables the moving height of the connecting frame to be accurately controlled.

[0014] In summary, compared with the prior art, the beneficial effects of this solution are:

[0015] (1) The utility model uses the arrangement of a rotating roller, a ball-end lever, and a push cylinder, so that the outer portion of the wire can be elastically limited and moved at multiple points during the winding and unwinding process. The limit distance and pressure can also be adjusted, which effectively avoids the loosening and tangling of the wire and ensures the use effect.

[0016] (2) The utility model provides the air cylinder and the air jet seat so that dry air can flow inside the wire storage cylinder and between the wires, which can effectively reduce the humidity inside the wire storage cylinder and improve the overall service life and safety of the wire storage cylinder.

[0024] 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:

[0025] refer to Figure 1-7A charging pile with a winding structure includes a charging pile 33 and a wire storage drum 34. The wire storage drum 34 is arranged on an end surface of one side of the charging pile 33. A material drum 38 is rotatably arranged inside the wire storage drum 34. A wire 39 is wound on the outer circumferential surface of the material drum 38. One end of the wire 39 extends out of the outer circumferential surface of the wire storage drum 34 and is connected to a charging gun 37. A plurality of connecting frames 41 are evenly slidably arranged on the outside of the material drum 38 along the circumferential direction. Rotating rollers 47 are rotatably arranged on both sides of each connecting frame 41. A plurality of ball head levers 44 are arranged between the two rotating rollers 47. An air jet seat 42 is arranged on the end surface of the connecting frame 41, and a heating plate 43 is arranged in the air jet seat 42.

[0026] Specifically, the charging pile 33 is a prior art, including an operation panel, a charging module, a cabinet door, a heat dissipation structure, etc., which are not elaborated in detail herein. The barrel 38 inside the wire storage barrel 34 completes the wire collection or wire release processing of the wire 39 by rotating clockwise or counterclockwise. One end of the wire 39 can extend to the outside of the wire storage barrel 34. The end of the wire 39 extending to the outside of the wire storage barrel 34 is connected to a charging gun 37. The wire 39 and the charging gun 37 are both prior art. The specific material and shape are not elaborated in detail herein. The illustration is for reference only. The user can pull the charging gun 37 to pull out the wire 39. During the pulling-out process, the barrel 38 will rotate, so that the wire 39 can be released smoothly, so that charging can proceed smoothly.

[0027] During the process of releasing or reeling in the wire 39, the multiple connecting frames 41 will always drive the two rotating rollers 47 to fit on the outer circumferential surface of the wire drum formed by the winding of the wire 39. The two rotating rollers 47 are rotatably arranged in the connecting frame 41. Therefore, when the wire 39 moves, the rotating rollers 47 will be driven to move, but the rotating rollers 47 as a whole will still press on the outer circumferential surface of the wire 39, so that the wire drum formed by the wire 39 will not be dispersed due to external pressure. The rotating rollers 47 are made of elastic material, which can better adapt to the uneven outer circumferential surface of the wire drum and provide a good limiting effect.

[0028] In the process of rotating the roller 47 to limit the position, the bottom of the ball-end lever 44 will also contact the outside of the wire drum. The ball-end lever 44 is made of elastic material and has a hemispherical bottom. When the wire 39 of the wire drum is abnormally bulged, the wire 39 will contact the ball-end lever 44. At this time, the wire 39 is in a moving state, so the ball-end lever 44 will vibrate during the contact process, thereby moving the bulged wire 39 to make it flat, reducing the occurrence of entanglement and knotting, and improving the winding quality.

[0029] During the movement of the wire 39, the jet seat 42 can spray gas to the wire 39 through the bottom, and the heating plate 43 can heat and dry the gas flowing into the jet seat 42, so that the gas sprayed to the outside of the wire 39 is in a dry state, thereby ventilating and drying the entire wire 39. In this relationship, the heating structure of the positioner 50 is a prior art and will not be elaborated in this article.

[0030] refer to Figure 5 A plurality of push cylinders 35 are evenly arranged on the outer circumferential surface of the wire storage barrel 34 along the circumferential direction, and the output end of the push cylinder 35 is connected to the end surface of the connecting frame 41.

[0031] Specifically, the pushing cylinder 35 is an existing technology, and an electric pushing cylinder, a pneumatic pushing cylinder, or a hydraulic pushing cylinder can be selected. This article will not elaborate on it. The output end of the pushing cylinder 35 can push the connecting frame 41 to move, ensuring that the rotating roller 47 and the ball head lever 44 can move according to the change in the diameter of the wire drum formed by the electric wire 39, thereby ensuring the winding quality.

[0032] refer to Figure 5 A plurality of positioners 50 are provided on the upper end surface of the air injection seat 42 .

[0033] Specifically, the positioner 50 can detect the moving distance of the jet seat 42 and the connecting frame 41 to ensure that the pressing height between the rotating roller 47 and the wire 39 meets the requirements and improve the limiting quality.

[0034] refer to Figure 5 A wind tube 36 is arranged on the outer circumferential surface of the wire storage cylinder 34 above the jet seat 42, and a second driving motor 45 is fixedly arranged in the wind tube 36. A rotating fan wheel 46 is connected to the output end of the second driving motor 45, and the wind tube 36 and the jet seat 42 are connected through a hose.

[0035] Specifically, the hose between the air duct 36 and the jet seat 42 can be elastically deformed, and the specific length can ensure the extreme movement of the connecting frame 41. The legend is for reference only and has no restrictive meaning. When gas needs to flow inside the jet seat 42, the second drive motor 45 can be started, thereby driving the rotating fan wheel 46 to rotate, thereby driving the gas outside the air duct 36 to flow into the air duct 36, and then poured into the jet seat 42 through the hose to complete the air supply process. In this relationship, the specific shape of the rotating fan wheel 46 is not restricted, and a fan blade shape with a better pressurization effect is preferably selected.

[0036] refer to Figure 4 A first drive motor 40 is disposed on one end surface of the wire storage barrel 34 , and an output end of the first drive motor 40 is connected to the end surface of the barrel 38 .

[0037] Specifically, when the barrel 38 needs to be wound or unwound, the output end of the first drive motor 40 can drive the barrel 38 to rotate to complete the winding or unwinding process. In this relationship, the first drive motor 40 is a prior art and can rotate forward and reverse, which is not elaborated in this article.

[0038] refer to Figure 4 A wire passing seat 48 is arranged on the outer circumferential surface of the wire storage barrel 34 outside the wire 39.

[0039] Specifically, the middle part of the wire holder 48 is in the shape of a through hole and is arranged on the outer circumferential surface of the wire storage barrel 34. One end of the wire 39 passes through the wire holder 48 and extends to the outside of the wire storage barrel 34, so that the charging gun 37 can be smoothly connected to the wire 39 to complete the charging process. Embodiment 2:

[0040] On the basis of or different from the first embodiment, reference Figure 7 A plurality of convex strips 49 are arranged on the outer circumferential surface of each rotating roller 47 .

[0041] Specifically, the provision of the convex strip 49 effectively improves the surface roughness of the outer cylindrical surface of the rotating roller 47, so that when the rotating roller 47 contacts the electric wire 39, the occurrence of slippage is reduced, and the limiting and fixing effect is effectively improved.

[0042] 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. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0043] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0044] The above description shows and describes several preferred embodiments of the present application, but as mentioned above, it should be understood that the present application is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the application concept described herein through the above teachings or the technology or knowledge of the relevant field.
