Description

A new energy fast charging pile with a wire-receiving device Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a new energy fast charging pile with a wire-receiving device. Background Art

[0002] Against the backdrop of global carbon neutrality and the development of intelligent technology, a growing number of new energy vehicles are entering the market. Currently, these vehicles, including hydrogen-powered vehicles, hybrid vehicles, and the most common pure electric vehicles, are mostly powered by onboard power and require charging stations to replenish power. Consequently, a large number of fast-charging vehicle charging stations have been rapidly deployed.

[0003] Existing fast-charging car charging piles are mainly composed of charging boxes, charging cables, and charging guns. Charging cables are generally long, exposed to the outside, and usually not well organized. Charging cables are generally hung on the charging pile. The long charging cables are easily tangled, causing the charging cables to break. If they fall, they will be run over by cars and cause damage. In some environments, the charging cables will age faster when exposed to sunlight, shortening their service life. In addition, during the charging process, it is easy for the cables to hang on the ground, which will not only make the cables contaminated with dust, but also aggravate the wear of the cable insulation layer. After charging is completed, the charging gun and cable need to be manually retracted, which not only increases the workload and makes the charging process cumbersome, but also the cables cannot be automatically retracted and are exposed to the outside. Over time, this will shorten the service life of the cables and bring safety hazards.

[0004] Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a new energy fast charging pile with a wire-taking device. By adjusting the settings of the bracket and the lifting wire storage assembly, the charging cable and charging gun can be easily accessed and stored, thereby reducing the difficulty of use and extending the service life and safety of the charging cable.

[0006] The present invention adopts the following technical solution: a new energy fast charging pile with a wire take-up device, comprising a storage rack and a charging assembly stored in the storage rack, the charging assembly comprising a charging cable and a charging gun connected to each other, an opening formed on one side of the storage rack, an adjustment bracket provided at the opening, and a lifting wire storage assembly provided in the storage rack;

[0007] The adjustment bracket includes a placement seat, a first frame and a second frame. The placement seat is arranged on the first frame and is used to place the charging gun. The first frame is reciprocatingly arranged on the second frame, so that the first frame can adjust the position of the placement seat and the charging gun thereon to move closer to or away from the second frame. The second frame is rotatably arranged on the storage rack. When the first frame moves to overlap with the second frame for storage, the placement seat and the charging gun thereon are accommodated in the opening by rotating the second frame.

[0008] The lifting and wire storage assembly includes an inner bracket, a wire take-up wheel and an elastic member. The elastic member is arranged on the upper part of the inner bracket. The upper part of the wire take-up wheel is connected to the elastic member and is movable up and down on the inner bracket. The input end of the charging cable is located on one side of the inner bracket. The charging cable passes around the wire take-up wheel to form an inverted U-shaped hanging state, and the charging cable is connected to the charging gun. When the first frame is driven away from or close to the storage rack, the charging cable is synchronously pulled out or retracted into the opening, and the wire take-up wheel descends or rises on the inner bracket to adapt to the length of the charging cable. The elastic member stores or releases elastic force to make the wire wheel balanced in its position or lift and lower smoothly.

[0009] As an improvement, rollers for rolling support of the charging cable are provided in the second frame and / or the storage rack.

[0010] As an improvement, the first frame has a panel, and when the second frame is rotated so that the placement seat and the charging gun thereon are accommodated in the opening, the panel covers the opening.

[0011] As an improvement, a handle for manual force application is provided at the outer end of the first frame.

[0012] As an improvement, a horizontal limit block is provided in the storage rack, and a hydraulic buffer is installed at the horizontal limit block. The second frame body contacts the hydraulic buffer for buffering. When the second frame body is rotated outward from the opening and into position, the rear end contacts the hydraulic buffer for buffering and limiting, thereby making the second frame body and the first frame body horizontal, and the first frame body performs horizontal reciprocating motion relative to the second frame body.

[0013] As an improvement, the placement seat forms a placement space for the charging gun. A hanging plate is provided on the outside of the placement space. A groove structure is provided on the hanging plate. A movable clip is provided on the charging gun. When the charging gun is placed in the placement space, the clip is movable and clamped in the groove structure for cooperation and limitation.

[0014] As an improvement, a fixing bracket for limiting the charging cable is provided at the lower portion of the inner bracket.

[0015] As an improvement, the take-up wheel is rotatably arranged on a arranging frame, the upper part of the arranging frame is connected to the elastic member, and rollers are arranged on both sides of the arranging frame, and the rollers are rotatably arranged on the track of the inner bracket.

[0016] As an improvement, the roller is a V-shaped guide roller, the middle part of which is clamped on the track to limit the left and right positions and to roll up and down.

[0017] As an improvement, the elastic member is a constant force spring.

[0018] Beneficial effects of the present invention:

[0019] 1. The elastic force of the elastic part balances the weight of the take-up wheel and the charging cable hanging on it, making it easier for users to use and store the charging gun and charging cable, reducing the difficulty of operation.

[0020] 2. The charging cable maintains an inverted U-shaped hanging state when it is being retracted or released, and there will be no entanglement or cable breakage. Compared with the traditional wrap-around storage method, it avoids the electromagnetic circulation generated by the original wrap-around method, which in turn causes temperature differences that affect charging efficiency and bring safety hazards, thereby greatly improving safety.

[0021] 3. The charging cable does not need to be removed when used. The reciprocating movement of the first frame and the second frame drives the charging cable and the charging gun to the appropriate position, and then the charging cable and the charging gun are taken out. Compared with the user taking the charging cable and the charging gun by themselves, it is more labor-saving and reduces the risk of wear and tear and tripping caused by the original cable hanging on the ground.

[0022] 4. By adjusting the overall rotation of the bracket, the charging cable and charging gun can be stored in the storage rack to avoid wind, sun, or external bumps and damage, thereby extending the service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] As shown in Figures 1, 2, 3, and 4, a specific embodiment of a new energy fast charging pile with a wire take-up device of the present invention is shown. This embodiment includes a storage rack 1 and a charging assembly 2 stored in the storage rack 1. The charging assembly 2 includes a charging cable 21 and a charging gun 22 connected to each other. An opening 11 is formed on one side of the storage rack 1, and an adjustment bracket 3 is provided at the opening 11. A lifting wire storage assembly 4 is provided in the storage rack 1.

[0029] The adjustment bracket 3 includes a placement seat 31, a first frame 32, and a second frame 33. The placement seat 31 is arranged on the first frame 32 and is used to place the charging gun 22. The first frame 32 is reciprocally arranged on the second frame 33, so that the first frame 32 can be adjusted to position the placement seat 31 and the charging gun 22 thereon to move closer to or away from the second frame 33. The second frame 33 is rotatably arranged on the storage rack 1. When the first frame 32 is moved to overlap with the second frame 33 for storage, the placement seat 31 and the charging gun 22 thereon are accommodated in the opening 11 by rotating the second frame 33.

[0030] The lifting wire storage assembly 4 includes an inner bracket 41, a take-up wheel 42 and an elastic member 43. The elastic member 43 is arranged on the upper part of the inner bracket 41. The upper part of the take-up wheel 42 is connected to the elastic member 43 and is movable up and down on the inner bracket 41. The input end of the charging cable 21 is located on one side of the inner bracket 41. The charging cable 21 passes around the take-up wheel 42 to form an inverted U-shaped hanging state, and the charging cable 21 is connected to the charging gun 22. When the first frame 32 is driven away from or close to the storage rack 1, the charging cable 21 is synchronously pulled out or retracted into the opening 11, and the take-up wheel 42 descends or rises on the inner bracket 41 to adapt to the length of the charging cable 21. The elastic member 43 stores or releases elastic force to make the wheel 42 balanced in its position or lift and lower smoothly.

[0031] When the present invention is in use, the input end of the charging cable 21 is connected to the charging box below the storage rack 1. The charging cable 21 is routed upward and around the take-up reel 42. It is then routed downward and the charging gun 22 at the output end is placed on the placement seat 31. By adapting the length of the charging cable 21 to the design, the charging cable 21 is prevented from hanging excessively. As shown in Figures 2, 3, and 4, the storage rack shell is removed to facilitate viewing of the interior, which is the standby state of the charging station. The adjustment bracket 3 is flipped as a whole into the storage rack 1, so that the charging cable 21 and charging gun 22 are stored in the storage rack 1. The first frame 32 and the second frame 33 are structurally overlapped to reduce the overall space occupied and achieve good protection and overall storage effects. The lifting and lowering cable storage assembly 4 and the adjustment bracket 3 are in the initial position, and the elastic member 43 balances the weight of the charging cable 21 and the take-up reel 42. As shown in Figure 1, when charging is needed, the user operates the adjustment bracket 3 to rotate it outward from the opening 11, and then pulls the first frame 32 outward, so that the first frame 32 and the second frame 33 are extended as a whole, and the placement seat 31 together with the charging gun 22 thereon are pulled to the required remote position, and the charging cable 21 is also pulled out synchronously, which adapts to the length of the first frame 32 and the second frame 33; the charging cable 21 is pulled and then synchronously drives the take-up wheel 42 to descend, and the charging cable 21 is supported on the take-up wheel 42 and extends and adjusts the support position in real time; the elastic member 43 stores elastic force, and the user can easily stretch the charging gun 22 carrying the placement seat 31 to the appropriate position, and the friction force of the first frame 32 and the second frame 33 offsets the elastic force, so that the take-up wheel 42 is balanced at the height position or smoothly raised and lowered, and the user removes the charging gun 22 and inserts it into the charging port of the new energy vehicle to perform the charging operation. When charging is complete, place the charging gun 22 back into the holder 31, then push the first frame 32 back until it overlaps with the second frame 33. The elastic member 43 releases its force, and the charging cable 21 and the take-up wheel 42 rise to their initial positions. The bracket 3 is then rotated and adjusted to fit within the opening 11 for optimal storage. Compared to the traditional manual method of retrieving the charging cable 21 and charging gun 22, the structural design of the present invention allows users to more easily adjust the charging cable 21 and charging gun 22 to the position where the new energy vehicle is parked, and then retrieve them. Once charging is complete, the entire unit is stored back in the storage rack 1 to avoid exposure to wind and sun, extending its service life.

[0032] As an improved specific implementation manner, rollers 5 for rolling support of the charging cable 21 are provided in the second frame 33 and / or the storage rack 1 .

[0033] As shown in Figures 1, 2, and 3, the extension and retraction of the charging cable 21 will cause its length and position to change, and the charging cable 21 may sag. If it causes drag and friction with the various parts of the frame, the service life of the charging cable 21 may be affected over time. Therefore, rollers 5 are further provided to support the charging cable 21. During the extension and retraction process, the charging cable 21 rolls on the rollers 5, reducing operational resistance, making it easier for users, and preventing wear on the charging cable 21. Multiple rollers can be arranged at the pulling position of the charging cable 21 as needed to improve the support effect.

[0034] As an improved embodiment, the first frame 32 has a panel 321 . When the second frame 33 is rotated to accommodate the placement seat 31 and the charging gun 22 thereon in the opening 11 , the panel 321 covers the opening 11 .

[0035] As shown in Figures 1, 2, 3, and 4, the shape of the panel 321 is adapted to the shape of the opening 11. When the panel 321 covers the opening 11, the opening 11 is effectively sealed to prevent debris from entering the opening 11, thereby better protecting the structure of the entire charging pile, extending its service life, and making the outer shell of the storage rack 1 more integrated, thereby ensuring its aesthetics.

[0036] As an improved specific implementation manner, a handle 322 for manual force application is provided at the outer end of the first frame 32 .

[0037] As shown in FIG. 1 , 2 , and 4 , the handle 322 is provided to facilitate the user to push and pull the first frame 32 , and to rotate and flip the bracket 3 to apply force outward or upward when adjusting the bracket 3 .

[0038] As an improved specific implementation method, a horizontal limit block 6 is provided in the storage rack 1, and a hydraulic buffer 61 is installed at the horizontal limit block 6. The second frame 33 abuts against the hydraulic buffer 61 for buffering. When the second frame 33 rotates outward from the opening 11 to its position, the rear end abuts against the hydraulic buffer 61 for buffering and limiting, thereby making the second frame 33 and the first frame 32 in a horizontal state, and the first frame 32 performs horizontal reciprocating motion relative to the second frame 33.

[0039] As shown in Figures 1, 2, and 3, the horizontal limit blocks 6 are provided on both sides of the storage rack 1. The inner end of the second frame 33 is rotatably provided on the storage rack 1 via a rotating shaft. When the second frame 33 rotates to a horizontal state, the second frame 33 is limited by the horizontal limit blocks 6, thereby keeping the first frame 32 and the second frame 33 horizontal. In this way, the extension and retraction of the first frame 32 are both performed on a horizontal plane, which can well maintain a smooth pulling state and make the user's operation more convenient. The movement and storage of the charging cable 21 and the charging gun 22 are more orderly and convenient. Preferably, the oil pressure buffer 61 provided at the horizontal limit block 6 can buffer the friction of the oil pressure buffer 61 when the operator flips the entire bracket relatively quickly, reducing the impact between the structures and avoiding the possibility of damage caused by collision between the adjustment bracket 3 and the horizontal limit block 6. As the adjustment bracket 3 finally stays in a horizontal state, normal horizontal position adjustment can be performed.

[0040] As an improved specific embodiment, the placement seat 31 forms a placement space 311 for placing the charging gun 22. A hanging plate 312 is provided on the outside of the placement space 311. A groove structure 313 is provided on the hanging plate 312. A movable clamp is provided on the charging gun 22. When the charging gun 22 is placed in the placement space 311, the clamp is movable and clamped in the groove structure 313 for cooperation and limitation.

[0041] As shown in Figure 1, the width and bottom of the placement space 311 are adapted to the size and shape of the charging gun 22, which facilitates the stable placement of the charging gun 22. Because the entire frame needs to be flipped over for storage, the charging gun 22 and the placement space 311 will be erected, so a hanging plate 312 is further provided. A clip can be provided on the charging gun 22. The clip is movable and clamped on the hanging plate 312 through elasticity, hinges, springs and other structures. Through the design of the groove structure 313, the clip is inserted into the groove structure 313 to achieve structural limitation. Therefore, when the frame and the charging gun 22 are flipped over for storage, the stable placement and storage of the charging gun 22 can also be guaranteed.

[0042] As an improved specific implementation, a fixing bracket 40 for limiting the position of the charging cable 21 is provided at the lower portion of the inner bracket 41 .

[0043] As shown in Figures 2 and 3, the charging cable 21 extends upward from the bottom. The input position of the charging cable 21 lacks structural matching and limiting, so a fixed bracket 40 is added to limit the lower charging cable 21 to ensure a better storage effect.

[0044] As an improved specific implementation, the first frame 32 and the second frame 33 form slide rails 34 on both sides that slide and cooperate with each other. The first frame 32 and the second frame 33 move closer to or away from each other through the sliding of the slide rails 34.

[0045] As shown in Figures 1 and 2, the slide rails 34 on both sides make the sliding of the first frame 32 and the second frame 33 smoother, and the supports on both sides make the overall sliding stable; it is also convenient to hollow out the middle so that the charging cable 21 can droop naturally when pulled out to a longer length, without dragging and wearing against the frame.

[0046] As an improved specific embodiment, the take-up wheel 42 is rotatably set on a layout frame 421, the upper part of the layout frame 421 is connected to the elastic member 43, and rollers 422 are set on both sides of the layout frame 421, and the rollers 422 are rollingly set on the track 411 of the inner bracket 41.

[0047] As shown in Figures 2, 3, and 4, the arrangement frame 421 is suspended by an upper elastic member 43 and is restrained on both sides by rollers 422 on the inner bracket 41. This allows for rolling coordination during up and down movement, ensuring that friction or other resistance matches the force applied to the elastic member 43, ensuring proper operation of the entire mechanism. The take-up wheel 42 rotates on the arrangement frame 421, rotating and raising and lowering with minimal resistance as the charging cable 21 is extended and retracted.

[0048] As an improved specific implementation method, the roller 422 is a V-shaped guide roller, and the middle part of the V-shaped guide roller is clamped on the track 411 to limit the left and right positions and roll up and down.

[0049] As shown in Figures 3 and 4, the V-shaped guide roller is adapted to the specific V-shaped track 411 to achieve a good left and right limit state, and when lifting, the adapted structure can roll up and down stably.

[0050] As an improved specific implementation, the elastic member 43 is a constant force spring.

[0051] By limiting the selection of the specific elastic member 43, a constant force spring can be selected according to the specific usage scenario and cost requirements to rely on the elastic force of the spring to balance the weight of the charging cable 21 and the take-up wheel 42, ensuring that the charging cable 21 and the charging gun 22 can be easily accessed and stored.

[0052] 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 based on the principles of the present invention are within the scope of protection of the present invention. It should be noted that improvements and modifications that do not depart from the principles of the present invention are within the scope of protection of the present invention.
