Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of new energy charging facilities, and in particular to a wiring harness spring fixing structure applied to a new energy charging station. Background Art
[0002] As new energy vehicles become more and more popular, the number of new energy charging stations as supporting facilities is also growing rapidly to meet the growing demand for charging. In these charging stations, effective management and proper fixing of charging cables have become key links to ensure safe and efficient operations.
[0003] However, most traditional charging cable fixing methods use simple hooks or binding straps, but these methods have exposed many shortcomings in practical applications. Due to loose fixing or unreasonable design, the charging cable is often easy to drag on the ground, which not only accelerates the wear of the charging cable and shortens its service life, but also may cause a series of safety hazards due to long-term friction with the ground. For example, severely worn charging cables are more likely to leak electricity, which may not only cause damage to the vehicle, but also endanger personnel safety; at the same time, the exposed wires caused by wear may also cause short circuit failures, affecting the normal operation of the entire charging station, and even causing serious consequences such as fire.

[0020] (III) Beneficial effects
[0021] Compared with the prior art, the present invention provides a method having the following beneficial effects:
[0022] 1. The present invention effectively prevents the charging cable from dragging on the ground by providing an anti-mopping mechanism, including a wire guide assembly and a wire suspension assembly. The spiral coil and the wire guide cylinder in the wire guide assembly provide clear guidance for the charging cable, while the expansion nut can firmly fix the charging cable inside it, and the variable pitch spring in the wire suspension assembly provides an oblique upward support force for the charging cable, ensuring that the charging cable always maintains a certain distance from the ground, thereby avoiding friction between the charging cable and the ground, extending the service life of the charging cable, and improving the safety of the charging station.
[0023] 2. The present invention effectively prevents the wear of the charging cable by providing a wire anti-wear member. The rubber tube and the internal reinforcement tube in the wire anti-wear member together form a solid protective layer, which can prevent direct contact and friction between the charging cable and the variable pitch spring. At the same time, the airbag on the inner wall of the rubber tube can fit tightly to the outside of the charging cable after inflation, further reducing the friction between the charging cable and surrounding components, providing additional fixation and protection for the charging cable, and effectively preventing the wear of the charging cable.
[0024] 3. The present invention effectively prevents the spiral coil from rebounding by setting up an anti-rebound mechanism. The conical tube and the conical male magnet block in the anti-rebound mechanism cooperate with the female magnet block mounting tube and the conical female magnet block on the outside of the spiral coil, and overcome the rebound force of the spiral coil through magnetic adsorption, ensuring that the charging cable remains stable and not easy to fall off during the pulling process. This design not only improves the stability of the charging cable, but also makes the entire device safer and more reliable.
[0025] 4. The present invention effectively solves the heat dissipation problem of the charging cable by providing a wire heat sink. The heat dissipation holes in the wire heat sink are evenly distributed on the rubber tube in a circular shape, and are equipped with an annular thin-walled tube made of shape memory alloy. When the charging cable generates heat during use, the heat can be discharged to the outside through the heat dissipation holes. At the same time, as the temperature rises, the aperture of the annular thin-walled tube will become larger, further improving the heat dissipation effect of the charging cable. This design ensures the safe use of the charging cable and improves the operating efficiency of the entire charging station. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The present invention provides a technical solution:
[0052] See also Figures 1 to 10 The wire harness spring fixing structure used in the new energy charging station includes a mounting plate 1 and a base 2 fixedly mounted on the outside of the mounting plate 1, and an anti-mopping mechanism 3 is arranged on the top of the base 2.
[0053] The anti-mopping mechanism 3 includes a wire guiding assembly 31 and a wire hanging assembly 32. The wire guiding assembly 31 and the wire hanging assembly 32 effectively avoid the contact between the charging cable and the ground, which not only prevents the wear and safety hazards caused by the charging cable dragging on the ground, but also improves the stability and service life of the charging cable.
[0054] The wire guide assembly 31 includes a spiral coil 311 fixedly installed at the top center of the base 2, a connecting plate 312 fixedly installed on the top of the spiral coil 311, a wire guide cylinder 313 fixedly connected to the connecting plate 312 passes through the connecting plate 312, and an expansion nut 314 is threadedly connected to the lower end of the wire guide cylinder 313. The wire guide assembly 31 composed of the spiral coil 311, the connecting plate 312, the wire guide cylinder 313 and the expansion nut 314 can firmly fix the charging cable to prevent it from dragging on the ground and wearing, ensure the safety and order of the charging cable, avoid the safety hazards that are easily caused by traditional fixing methods, and ensure the safe and efficient operation of the charging station.
[0055] The wire suspension assembly 32 includes a variable pitch spring 321 fixedly installed on one end of the wire harness guide tube 313 away from the expansion nut 314, and a wire anti-wear part 322 is fixedly installed on the inner side of the variable pitch spring 321. A wire heat sink 323 is arranged inside the wire anti-wear part 322. The variable pitch spring 321 provides support, the wire anti-wear part 322 prevents wear, and the wire heat sink 323 enhances heat dissipation, which together protect the charging cable, ensure its stable suspension and extend its service life.
[0056] Further, the spiral coil 311 uses The spring steel wire is wound into shape by spring production equipment; variable pitch spring 321 is used The spring steel wire is wound into shape by spring production equipment. The spiral coil 311 and the variable pitch spring 321 are wound with spring steel wire of a specific diameter to ensure structural strength and elasticity, effectively support and protect the charging cable, avoid mopping wear, and improve the safety of the charging station and the service life of the charging cable.
[0057] Furthermore, the wire wear-proof member 322 includes a rubber tube 3221 fixedly mounted on the inner side of the variable pitch spring 321, a reinforcing tube 3222 fixedly mounted inside the rubber tube 3221, a plurality of airbag mounting rings 3223 fixedly mounted on the inner wall of the rubber tube 3221, an airbag 3224 fixedly mounted in the inner cavity of the airbag mounting ring 3223, and a plurality of connecting tubes 3225 symmetrically mounted on the outer side of the airbag 3224, which are connected to the inner cavity of the airbag 3224 and penetrate the airbag mounting ring 3223. An inflation tube 3226 that penetrates the airbag mounting ring 3223 and the rubber tube 3221 is fixedly installed on the outer circumferential surface of one of the airbags 3224. The inflation end of the inflation tube 3226 is threadedly connected with a sealing cap 3227. The structure of the rubber tube 3221, the reinforcing tube 3222 and the airbag 3224 can effectively prevent the charging cable from directly contacting the variable pitch spring 321, reduce wear, and fit the charging cable tightly through inflation of the airbag 3224, providing additional fixation and protection to ensure the safety and stability of the charging cable.
[0058] Furthermore, the wire heat sink 323 includes a plurality of heat dissipation holes 3231 opened inside the rubber tube 3221, and an annular thin-walled tube 3232 is fixedly installed on the inner wall of the heat dissipation hole 3231. The heat dissipation holes 3231 are evenly distributed on the rubber tube 3221 in a circular shape and are located between the two air bags 3224. Through the combination of the heat dissipation holes 3231 and the shape memory alloy annular thin-walled tube 3232, the heat generated by the charging cable can be effectively discharged, the heat dissipation efficiency can be improved, the safe use of the charging cable can be ensured, and the operating efficiency of the charging station can be improved.
[0059] Furthermore, the reinforcing tube 3222 is made of an aluminum alloy hollow mesh tube, and the annular thin-walled tube 3232 is made of a shape memory alloy. The reinforcing tube 3222 uses an aluminum alloy hollow mesh tube to enhance structural strength and toughness, and the annular thin-walled tube 3232 uses a shape memory alloy to achieve automatic adjustment of heat dissipation efficiency as temperature changes, thereby jointly improving the protection of the device to the charging cable and the heat dissipation performance.
[0060] Furthermore, an anti-rebound mechanism 4 is provided on the outer side of the spiral coil 311, and the anti-rebound mechanism 4 includes an anti-rebound tube 41 fixedly installed on the top of the base 2 and located on the outer side of the spiral coil 311, and a conical cylinder 42 is fixedly installed on the top of the anti-rebound tube 41, and a conical male magnet block 43 is fixedly installed on the inner conical surface of the conical cylinder 42. The anti-rebound mechanism 4 also includes a female magnet block mounting cylinder 44 fixedly installed on the outer side of the spiral coil 311 and located in the conical cylinder 42, and a conical female magnet block 45 is fixedly installed on the top of the female magnet block mounting cylinder 44. Through magnet adsorption, the rebound of the spiral coil 311 is effectively overcome, ensuring that the charging cable is stable and not easy to fall off. At the same time, the equal taper design facilitates the multi-directional rotation of the charging cable and improves operational flexibility.
[0061] Furthermore, the conical cylinder 42, the conical male magnet block 43 and the conical female magnet block 45 have the same taper. The conical cylinder 42, the conical male magnet block 43 and the conical female magnet block 45 ensure uniform and stable magnetic adsorption, facilitate flexible rotation of the charging cable in all directions, and improve the convenience and safety of charging operation.
[0062] Furthermore, the workpieces on the anti-mopping mechanism 3 and the anti-rebound mechanism 4 are subjected to electrophoretic treatment and powder spraying treatment. The anti-mopping mechanism 3 and the anti-rebound mechanism 4 are subjected to electrophoretic treatment and powder spraying treatment to enhance the corrosion resistance and wear resistance of the workpiece surface, thereby ensuring the long-term stable operation of the device in a complex environment and improving the durability and safety of the overall structure.
[0063] When used specifically, the working principle of the present invention is as follows:
[0064] When using the wire harness spring fixing structure applied to the new energy charging station, the whole device is first firmly installed at the designated position of the charging station through the close cooperation between the mounting plate 1 and the screws. Then, the operator can easily take out the charging cable and pass it through the wire guide assembly 31 and the wire suspension assembly 32 on the anti-mopping mechanism 3 in sequence according to the designed path.
[0065] Specifically, the charging cable first passes through the harness guide tube 313 and the expansion nut 314. This solid cylindrical structure provides a clear guide for the charging cable. At the same time, the expansion nut 314 can be rotated to firmly clamp and fix the contact surface between the charging cable and the inner side of the expansion nut 314. This design not only improves the stability of the charging cable, but also effectively prevents safety hazards caused by shaking or falling off of the charging cable.
[0066] Then, the charging cable will continue to pass through the variable pitch spring 321. The coordinated action of the variable pitch spring 321 and the spiral coil 311 provides an oblique upward support force for the charging cable, effectively avoiding the contact between the charging cable and the ground, thereby extending the service life of the charging cable and improving the safety of the charging station.
[0067] In addition, in order to further enhance the protection of the charging cable, the device is also designed with a wire wear-proof part 322. The rubber tube 3221 and the internal reinforcement tube 3222 (made of an aluminum alloy hollow mesh tube) in this structure together form a solid protective layer. The reinforcement tube 3222 can significantly improve the strength and toughness of the rubber tube 3221, making it more able to withstand external pressure or impact force, thereby extending the service life of the rubber tube 3221. The wire wear-proof part 322 can prevent direct contact and friction between the charging cable and the variable pitch spring 321. At the same time, the airbag 3224 on the inner wall of the rubber tube 3221 can fit tightly on the outside of the charging cable after inflation, providing additional fixation and protection for the charging cable.
[0068] It is worth mentioning that the device also has the function of 360-degree full-range rotation. Both the spiral coil 311 and the variable pitch spring 321 can be rotated according to actual needs, so that the operator can adjust the direction and position of the charging line. This flexibility not only improves the charging efficiency, but also makes the entire device easier to operate and maintain.
[0069] In actual use, when the charging cable is pulled, the spiral coil 311 may be subjected to tension and rebound. In order to solve this problem, the device is designed with an anti-rebound mechanism 4. The operator only needs to pull the charging cable hard so that the conical female magnet block 45 on the spiral coil 311 is in close contact and adsorbed with the conical male magnet block 43 on the conical cylinder 42, so as to effectively overcome the rebound force of the spiral coil 311. This magnetic adsorption design is not only simple and practical, but also ensures that the charging cable remains stable and not easy to fall off during the pulling process. At the same time, since the tapers of the conical cylinder 42, the conical male magnet block 43 and the conical female magnet block 45 are equal, the magnetic force is more uniform and stable, and it is also convenient for the charging cable to rotate in all directions.
[0070] Last but not least, the device also takes into account the heat dissipation of the charging cable. In the wire heat sink 323, the heat dissipation holes 3231 are evenly distributed on the rubber tube 3221 in a circular shape and are located between the two air bags 3224. These heat dissipation holes 3231 are not only numerous and evenly distributed, but also equipped with an annular thin-walled tube 3232 made of shape memory alloy. When the charging cable generates heat during use, the heat can be discharged to the outside through the heat dissipation holes 3231. At the same time, as the temperature rises, the aperture of the annular thin-walled tube 3232 will become larger, thereby further improving the heat dissipation effect of the charging cable. This design not only ensures the safe use of the charging cable, but also improves the operating efficiency of the entire charging station.
[0071] In summary, the wire harness spring fixing structure used in new energy charging stations effectively solves many problems existing in the traditional charging cable fixing method through a series of ingenious designs and innovative technical means. It not only improves the stability and safety of the charging cable, but also extends the service life of the charging cable and reduces maintenance costs. At the same time, the device also has the advantages of simple operation, easy maintenance and good heat dissipation, providing a strong guarantee for the efficient operation of new energy charging stations.
[0072] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
