Description

Technical Field

[0001] This invention relates to the field of new energy vehicle technology, and in particular to a new energy fast charging pile with retractable wiring harness. Background Technology

[0002] With the development of intelligent technology, more and more new energy vehicles are beginning to occupy the market. Currently, new energy vehicles on the market include hydrogen fuel cell vehicles, hybrid electric vehicles, and the most common pure electric vehicles. Most of them are powered by onboard power sources and require charging stations to replenish their power consumption in a timely manner. Therefore, a large number of fast-charging stations have been rapidly deployed.

[0003] Existing fast-charging car charging stations mainly consist of a charging box, charging cables, and a charging gun. The charging cables are generally long and exposed, often without proper organization. They are typically suspended from the charging station, and their length makes them prone to tangling, breakage, and accidental falls that can be run over by vehicles, causing damage. In some environments, exposure to sunlight accelerates cable aging and shortens their lifespan. Furthermore, during charging, cables often dangle on the ground, attracting dust and accelerating insulation wear. After charging is complete, the charging gun and cable must be manually retrieved, increasing labor and making the process cumbersome. The lack of automatic cable retraction further shortens cable lifespan and poses safety hazards over time. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a new energy fast charging pile that can store wire harnesses. By setting up a lifting and storage mechanism and a charging gun telescopic mechanism, the charging cables and charging gun can be easily retrieved and stored, reducing the difficulty of use while extending the service life of the charging cables and improving the safety of use.

[0005] The present invention adopts the following technical solution: a new energy fast charging pile with retractable wire harness, including a bracket and a charging component housed in the bracket. The charging component includes a charging cable and a charging gun connected to each other. The bracket is also provided with a lifting and storing mechanism and a charging gun telescopic mechanism. The lifting and storing mechanism includes an elastic element and a lifting frame. The elastic element is located on the upper part of the bracket. The upper part of the lifting frame is connected to the elastic element and is mounted on the bracket vertically. The input end of the charging cable is located on one side of the bracket. The charging cable passes around the lifting frame to form an inverted U-shaped suspension state. The charging gun telescopic mechanism includes a linkage group and a storage seat. The two ends of the linkage group are respectively connected to the bracket and the storage seat. The linkage group extends and retracts horizontally to move the storage seat closer to or away from the bracket. The charging gun connected to the output end of the charging cable is detachably placed in the storage seat. When the storage seat is driven away from or closer to the bracket, the lifting frame is lowered or raised by synchronously driving the charging cable. The elastic element stores or releases elastic force to keep the lifting frame balanced in its position or to lift and lower smoothly.

[0006] As an improvement, the lifting frame includes an inverted T-shaped main frame with rollers on the top and sides for the charging cable to pass over and provide rolling support.

[0007] As an improvement, the circumference of the roller is formed with a groove to accommodate the charging cable.

[0008] As an improvement, the main frame has a limiting frame on the outside of the roller to block the charging cable, which passes between the limiting frame and the roller.

[0009] As an improvement, an auxiliary winding roller is also provided on the bracket at the height corresponding to the lifting and storing mechanism. After the charging cable passes around the lifting frame, it continues to pass around the auxiliary winding roller from below, so that the charging gun at the output end is placed on the storage base.

[0010] As an improvement, the elastic element is a spring balancer, a constant force spring, or a spiral spring.

[0011] As an improvement, the linkage group includes several main rods and several auxiliary rods. The main rods and auxiliary rods are hinged end to end to form a telescopic group. The main rods and auxiliary rods of two telescopic groups are hinged in the middle to form a telescopic cooperation state in the shape of a parallelogram.

[0012] As an improvement, a retaining ring is installed on the main rod or auxiliary rod to limit the charging cable. When the linkage group extends or retracts, the retaining ring drives the charging cable to move horizontally, thereby linking the extension and retraction of the charging cable.

[0013] As an improvement, the storage base is also equipped with a limiting ring for the charging cable to pass through. When the charging gun is removed from the storage base, the charging cable is pulled in the limiting ring to move the charging gun.

[0014] As an improvement, the linkage assembly includes several sleeve rods that are sequentially nested together. These sleeve rods extend and retract by axial displacement, and the sleeve rods at both ends are connected to a bracket and a storage base, respectively.

[0015] The beneficial effects of this invention are:

[0016] 1. The elastic force of the lifting frame and the weight of the charging cable suspended on it are balanced by the elasticity of the elastic element, making it easier for users to use and store the charging gun and charging cable, and reducing the difficulty of operation.

[0017] 2. The charging cable is suspended in an inverted U-shape when being retracted or extended, preventing tangling and cable breakage. Compared to the traditional method of wrapping the cable around, this avoids electromagnetic currents that can cause temperature differences that affect charging efficiency and pose safety hazards, thus greatly improving safety.

[0018] 3. The charging cable does not need to be removed for use. The charging cable and charging gun can be accessed by the linkage group, which avoids the risk of the cable hanging on the ground and getting worn or tripped. In addition, it is stored in the bracket to avoid wind and sun exposure and extend its service life. Attached Figure Description

[0024] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 , 2Figures 3, 4, and 5 show a specific embodiment of the new energy fast charging pile with retractable wire harness of the present invention. This embodiment includes a bracket 1 and a charging assembly 2 housed in the bracket 1. The charging assembly 2 includes a charging cable 21 and a charging gun 22 connected to each other. The bracket 1 is also equipped with a lifting and storing mechanism 3 and a charging gun telescopic mechanism 4. The lifting and storing mechanism 3 includes an elastic element 31 and a lifting frame 32. The elastic element 31 is located on the upper part of the bracket 1, and the upper part of the lifting frame 32 is connected to the elastic element 31 and is vertically movable on the bracket 1. The input end of the charging cable 21 is located on one side of the bracket 1, and the charging cable 21 is suspended in an inverted U-shape around the lifting frame 32; the charging gun... The telescopic mechanism 4 includes a linkage 41 and a storage seat 42. The two ends of the linkage 41 are connected to the bracket 1 and the storage seat 42 respectively. The linkage 41 extends and retracts horizontally to move the storage seat 42 closer to or away from the bracket 1. The charging gun 22 connected to the output end of the charging cable 21 is detachably placed at the storage seat 42. When the storage seat 42 is driven away from or closer to the bracket 1, the lifting frame 32 is lowered or raised by synchronously driving the charging cable 21. The elastic element 31 stores or releases the elastic force to keep the lifting frame 32 balanced in its position or to lift and lower smoothly.

[0026] In use, the input end of the charging cable 21 is connected to the charging box under the bracket 1. The charging cable 21 runs upward and around the lifting frame 32, then runs downward and places the charging gun 22 at the output end on the storage base 42. Through the adaptation design of the charging cable 21's length, the charging cable 21 is prevented from dragging on the ground. Figure 1 As shown, this is the standby state of the charging pile: the lifting and storage mechanism 3 and the charging gun telescopic mechanism 4 are in their initial positions. The elastic element 31 balances the weight of the charging cable 21 and the lifting frame 32. The charging cable 21 hangs down partially and does not contact the ground. Figure 2 As shown, when charging is needed, the connecting rod assembly 41 and the storage seat 42 are extended manually or automatically. The charging cable 21 is pulled, which in turn drives the lifting frame 32 to descend. The charging cable 21 is supported on the lifting frame 32 and its support position is adjusted in real time. The elastic element 31 stores the elastic force, allowing the user to easily extend the charging gun 22, which carries the storage seat 42, to a suitable position. The friction between the connecting rod assembly 41 and the storage seat 42 counteracts the elastic force, allowing the lifting frame 32 to remain balanced at its current height or to rise and fall smoothly. The user can then remove the charging gun 22 and insert it into the charging port of the new energy vehicle to begin charging. After charging is complete, the charging gun 22 is placed back into the storage seat 42. Then, the connecting rod assembly 41 and the storage seat 42 are manually or automatically driven back to the bracket 1. The elastic element 31 releases the elastic force, and the charging cable 21 and the lifting frame 32 rise to their initial positions, achieving efficient storage.

[0027] As an improved specific implementation, the lifting frame 32 includes an inverted T-shaped main frame 321, with rollers 322 arranged on the upper part and sides for the charging cable 21 to pass around and provide rolling support.

[0028] like Figure 1 , 2 As shown in Figures 3 and 4, three support points, specifically rollers 322, are provided on the top and sides of the inverted T-shaped main frame 321. When the main frame 321 is raised or lowered, the support adjustment of the charging cable 21 is achieved by rolling it on the rollers 322, thereby reducing the friction of the charging cable 21 during adjustment, making the structure operate more smoothly during use, making manual operation easier, and preventing surface wear on the charging cable 21. In the structural design, the winding radius formed by the three rollers 322 on the inverted T-shaped main frame 321 exceeds 200mm, making it less prone to damage when the charging cable 21 bends in a large diameter state.

[0029] As an improved specific implementation, the circumferential surface of the roller 322 forms a groove 323 for accommodating the charging cable 21.

[0030] like Figure 1 , 2 As shown in Figures 3 and 4, the design of the groove 323 allows the charging cable 21 to be better confined within the groove 323 for rolling, whether it is supported on the side or the top of the roller 322, and it will not slide to the sides of the roller 322, thus ensuring better support and preventing bumps and wear.

[0031] As an improved specific implementation, the main frame 321 is provided with a limiting frame 324 on the outside of the roller 322 to block the charging cable 21, and the charging cable 21 passes through the limiting frame 324 and the roller 322.

[0032] like Figure 1 , 2 As shown in Figures 3 and 4, the space formed between the limiting frame 324 and the roller 322 is larger than the outer diameter of the charging cable 21, giving the charging cable 21 a certain amount of room to move and making it less likely to be bumped or worn during adjustment. The limiting frame 324 prevents the charging cable 21 from detaching from the roller 322 during adjustment, thus preventing the charging cable 21 from being damaged in its stored state, thereby ensuring that the charging cable 21 can be stored normally and that the charging component 2 can be used normally.

[0033] As an improved specific implementation, the bracket 1 is also provided with a secondary winding roller 5 at the height corresponding to the lifting and storing mechanism 3. After the charging cable 21 passes around the lifting frame 32, it continues to pass around the secondary winding roller 5 from below, so that the charging gun 22 at the output end is placed on the storage base 42.

[0034] like Figure 1 , 2 As shown in Figure 3, the auxiliary winding roller 5 allows the charging cable 21 to pass around from below, thus effectively restricting and guiding the cable's path. Specifically, the charging cable 21 first runs downwards in a roughly vertical position from the lifting frame 32, then passes around the auxiliary winding roller 5, and runs in a roughly horizontal position along the connecting rod assembly 41 to the storage seat 42. This achieves effective guidance and storage of the charging cable 21, preventing it from being pulled or swaying arbitrarily when the charging gun 22 is removed. The structure of the auxiliary winding roller 5 can be designed with reference to the roller 322 on the main frame 321, with the addition of a groove 323 to improve the limiting effect. The position of the auxiliary winding roller 5 can correspond to the upper side roller 322, maintaining a relatively vertical cable path for the charging cable 21.

[0035] As an improved specific implementation, the elastic element 31 is a spring balancer, a constant force spring, or a spiral spring.

[0036] By limiting the selection of specific elastic elements 31, one of the following implementation methods can be selected: spring balancer, constant force spring, or spiral spring, depending on the specific usage scenario and cost requirements. The spring force is used to balance the weight of the charging cable 21 and the lifting frame 32, ensuring easy access and storage of the charging cable 21 and the charging gun 22.

[0037] As an improved specific implementation, the linkage 41 includes several main rods 411 and several secondary rods 412. The main rods 411 and secondary rods 412 are hinged end to end to form a telescopic group. The main rods 411 and secondary rods 412 of two telescopic groups are hinged in the middle to form a telescopic cooperation state in the shape of a parallelogram.

[0038] like Figure 1 , 2 As shown in Figures 3 and 5, each telescopic group is connected in a zigzag pattern by several main rods 411 and auxiliary rods 412, which are sequentially hinged end to end. Each group of connected main rods 411 and auxiliary rods 412 forms two sides of a parallelogram. Two telescopic groups are combined, with the main rods 411 and auxiliary rods 412 of two groups sequentially hinged at the middle, forming a telescopic parallelogram structure. When the linkage group 41 is pushed or pulled manually or electrically, the charging gun 22 can be horizontally displaced. After extending to its full position, the charging gun 22 can move away from the bracket 1 and reach a suitable charging location to charge the parked vehicle. The linkage group 41 can be set at a height of approximately 1 meter above the ground for easy operation. Preferably, the linkage group 41 can extend 2-3 meters to move the charging gun 22 and charging cable 21 to a suitable parking space.

[0039] As an improved specific implementation, a retaining ring 413 for limiting the charging cable 21 is installed on the main rod 411 or the auxiliary rod 412. When the connecting rod group 41 extends or retracts, the retaining ring 413 drives the charging cable 21 to move horizontally, thereby linking the extension and retraction of the charging cable 21.

[0040] like Figure 1 , 2 As shown in Figures 3 and 5, by setting the retaining ring 413 to lock the charging cable 21, the extension and retraction of the charging cable 21 can be better synchronized during the extension and retraction of the linkage assembly 41, thereby better facilitating the smooth lifting and lowering of the lifting frame 32. Furthermore, by structurally locking the charging cable 21 and the linkage assembly 41, the charging cable 21 can be prevented from dragging on the ground at a suitable length, thus avoiding wear and tear. Preferably, the retaining ring 413 can be detachably and adjustably installed on a section of the main rod 411 or the auxiliary rod 412, thereby adjusting the locking position of the charging cable 21 and the linkage assembly 41 as needed.

[0041] As an improved specific implementation, the storage base 42 is also provided with a limiting ring 421 through which the charging cable 21 passes. When the charging gun 22 is removed from the storage base 42, the charging gun 22 is moved by pulling the charging cable 21 in the limiting ring 421.

[0042] like Figure 1 , 2 As shown in Figures 3 and 5, the upper part of the charging gun 22 is placed on the storage base 42, and the lower part is placed on the limiting ring 421, thus achieving good storage of the charging gun 22. When the charging gun 22 is taken out, the charging cable 21 is threaded through the limiting ring 421, which effectively limits the charging cable 21 and prevents it from being pulled or swayed arbitrarily, thus protecting the charging cable 21. By pulling the charging cable 21 in the limiting ring 421, the charging gun 22 can be easily taken out of the vehicle for charging. Preferably, a sufficiently long charging cable 21 is left between the retaining ring 413 and the storage base 42, ensuring that the charging cable 21 does not drag on the ground and that there is enough space for the charging gun 22 to be removed.

[0043] As an improved specific implementation, the linkage group 41 includes several sleeve rods that are sequentially sleeved. The sleeve rods are axially displaced to extend and retract, and the sleeve rods at both ends are respectively connected to the bracket 1 and the storage seat 42.

[0044] This embodiment is not shown in the accompanying drawings. By using several sequentially nested sleeves, the displacement adjustment of the charging cable 21 and charging gun 22 after extension and retraction can also be achieved, realizing the functionality and technical effects of the present invention. Preferably, a retaining ring can be provided on one of the sleeves to lock the charging cable 21, thus realizing the function of the retaining ring.

[0045] As an improved specific implementation, the lifting frame 32 and the support 1 move up and down through a slider in conjunction with rollers or guide rails.

[0046] like Figure 3 , 4 As shown, a slider can be installed on the lifting frame 32, and rollers or guide rails can be installed on the bracket 1 as needed to coordinate the lifting of the lifting frame 32, ensuring that the friction or other resistance is adapted to the force on the elastic element 31, and ensuring the normal use of the overall mechanism. In the structural design, the maximum lifting distance of the lifting frame 32 can be set to 1.25-1.5 meters, and the suspended charging cable 21 can be stored or extended by twice its length, thereby adapting to the extension length of the charging cable 21 of the linkage group 41.

[0047] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
