[0002] With the promotion of energy conservation and environmental protection and the development of new energy related technologies, new energy vehicles have become more and more popular.

[0003] New energy vehicles are mainly recharged through charging piles. Since the locations of charging ports are different on new energy vehicles of different brands and models, the charging gun cables on existing charging piles are generally set to be relatively long in order to adapt to the charging port locations of different new energy vehicles. When not in use, the cables are dragged on the ground, which will cause the cables to be soaked on rainy days. When the user pulls out the charging gun and inserts it into the car's charging port and returns the charging gun, the cable will be pulled to rub on the ground. After long-term use, these factors may cause damage to the cable structure, affecting its service life, and posing a safety hazard. Utility Model Content

Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0044] To address the problem of existing charging gun cables dragging on the ground due to their length, this application improves the system by raising the cables. Specifically, a cable tie is provided on the top of the elastic support rod, and the cables pass through the cable tie, which supports and raises the cables. When the user pulls the charging gun to charge, the elastic support rod bends and deforms with the tension on the cable. The elastic support rod bends toward the horizontal direction, increasing the horizontal length of the cable and ensuring that the charging gun can be moved to the car's charging port for connection and charging. During the charging process, the bent elastic support rod will continue to provide good support for the cable connected to the top cable tie as it recovers its deformation, ensuring that the elastic support rod can support and raise the charging gun's cable regardless of whether the charging gun is in use, so that the cable does not drag on the ground.

[0045] On the basis of the above improvements, the inventors of this application discovered in practice that when charging is completed and the gun is returned, the elastic support rod will vibrate with the cable tie during the process of recovering its deformation. This vibration will not only affect the stability of the assembly connection between the cable tie and the elastic support rod, causing the cable tie to loosen, but may also be transmitted to the user's hand holding the gun through the cable on the cable tie and the charging gun, affecting the user experience. In severe cases, the gun may fall off, leading to safety problems.

[0046] Based on this, the present application adopts the method of assembling the elastic support rod and the cable harness by interlocking and fixing two sleeve parts with each other, and further an elastic part compressed by the elastic support rod and the cable harness is sleeved on the outer periphery of the sleeve part. By utilizing the assembly gap between the two sleeve parts and the elastic force generated by the expansion tendency of the elastic part itself, the vibration transmission between the elastic support rod and the cable harness can be effectively slowed down, thereby ensuring the stability of the connection between the two and avoiding the vibration transmission to the user's hand as much as possible.

[0047] According to one aspect of the embodiment of the present application, a charging pile is provided. Figure 1 The figure shows the structure of a charging pile. As shown in the figure, the charging pile 500 includes: a wire take-up assembly 100, a cabinet 200, a charging gun 300, and a cable 400. One end of the cable 400 is connected to the cabinet 200, and the other end passes through the wire harness hole 121 on the wire harness 120 in the wire take-up assembly 100 and is connected to the charging gun 300.

[0048] In the specific embodiment shown in the figure, the charging pile 500 is a dual-gun charging pile, and the cable 400 connected to each charging gun 300 is supported by a wire take-up assembly 100 to prevent the cable 400 from dragging on the ground and affecting its service life and safety.

[0049] Another aspect of the present application embodiment provides a wire take-up assembly 100 that can be applied to the above-mentioned charging pile 500. For details, please refer to Figure 2 , the figure shows the three-dimensional structure of the take-up assembly 100. As shown in the figure, the take-up assembly 100 includes an elastic support rod 110, a cable tie 120 and a first elastic member 130. The elastic support rod 110 is used to be fixed relative to the cabinet 200 of the charging pile 500. Specifically, the elastic support rod 110 can be as follows Figure 1 As shown in FIG, it is directly assembled and fixed on the cabinet 200, and can also be assembled and fixed on the ground or wall near the cabinet 200, without specific limitation.

[0050] See next Figure 3 The figure shows the exploded structure of the take-up assembly 100. As shown in the figure, the top of the elastic support rod 110 is provided with a first sleeve portion 111, and the bottom of the cable tie 120 is provided with a second sleeve portion 122. The first sleeve portion 111 and the second sleeve portion 122 are mutually sleeved, and the first sleeve portion 111 and the second sleeve portion 122 are fixedly connected to each other by fasteners (such as pins, screws, etc.). The first elastic member 130 is sleeved on the first sleeve portion 111 and the second sleeve portion 122 and is compressed between the top of the elastic support rod 110 and the bottom of the cable tie 120.

[0051] Please combine Figures 1 to 3A cable hole 121 is provided on the cable tie 120 , and the cable hole 121 is used for the cable 400 of the charging gun 300 on the charging pile 500 to pass through.

[0052] When unplugging the charging gun 300 from the cabinet 200 to charge the car, the user holds the charging gun 300 and pulls it. After the pulling force acts on the cable 400, it is transmitted to the cable tie 120 through the cable 400, thereby driving the elastic support rod 110 to bend and deform. That is, the elastic support rod 110 will bend and deform with the force applied to the cable 400, presenting a similar Figure 4 As shown in the figure, compared with Figure 1 In the illustrated state, the horizontal length of the cable 400 is increased, ensuring that the user can pull the charging gun 300 to the vehicle's charging port for connection and charging. Furthermore, when the charging gun 300 is connected to the vehicle's charging port, the elastic support rod 110 has a tendency to recover its bent deformation. Therefore, it can still apply tension to the cable 400 during charging, keeping it upright and preventing it from dragging on the ground.

[0053] For details on the connection between the first sleeve portion 111 and the second sleeve portion 122, please refer to Figure 5 In the embodiment shown in the cross-sectional structure, the second sleeve portion 122 is assembled by sleeve-fitting the outer periphery of the first sleeve portion 111, and the two are fixed to each other internally by an axial fastener. In other embodiments, the first sleeve portion 111 may be assembled by sleeve-fitting the second sleeve portion 122, and radially inserted fasteners may be used to fix the two to each other.

[0054] like Figure 5 As shown in the figure, after the first sleeve portion 111 and the second sleeve portion 122 are sleeved, the first elastic member 130 will be compressed between the top 112 of the elastic support rod 110 and the bottom 123 of the cable tie 120. When the charging gun 300 is returned after charging, the elastic support rod 110 recovers its elastic deformation and rebounds, and the cable tie 120 will move along the Figure 4 The elastic support rod 110 rotates in the direction indicated by the middle arrow. During this process, part of the vibration generated by the elastic support rod 110 is transmitted to the cable harness 120, and the other part is transmitted to the first elastic member 130. Since there will inevitably be some assembly gaps between the first sleeve portion 111 and the second sleeve portion 122, the first elastic member 130 can be deformed after being affected by the vibration of the elastic support rod 110, so as to achieve a shock-absorbing effect and achieve the effect of slowing down the vibration transmission between the elastic support rod 110 and the cable harness 120. On the one hand, it ensures the structural stability of the connection between the cable harness 120 and the elastic support rod 110. On the other hand, it avoids as much as possible the vibration from being transmitted to the user's hand through the cable harness 120, the cable 400 and the charging gun 300 in sequence, causing dangerous situations such as the hand falling off the gun.

[0055] In summary, the wire take-up assembly 100 provided in the embodiment of the present application first allows the cable 400 to pass through the cable tie 120 fixed to the top of the elastic support rod 110, so as to raise the cable 400 high and prevent the cable 400 from touching the ground when the charging pile 500 is not in use. During use, the elastic support rod 110 is elastically bent under stress, so that when the user pulls the charging gun 300, the elastic support rod 110 bends horizontally, and the horizontal dimension of the cable 400 is extended, ensuring that the charging gun 300 can be connected to the car's charging port. During the charging process, the elastic support rod 110 can still raise the cable 400 to ensure that it does not touch the ground. Furthermore, in order to prevent the vibration caused by the rebound of the elastic support rod 110 when returning the gun from having a significant impact on the cable tie 120 and the user's hand, the cable tie 120 and the elastic support rod 110 are assembled in a sleeve-type manner and fixed to each other by fasteners. At the same time, a first elastic member 130 is compressed between the bottom 123 of the cable tie 120 and the top 112 of the elastic support rod 110. By utilizing the assembly gap of the sleeve between the cable tie 120 and the elastic support rod 110 and the deformation ability of the first elastic member 130, the transmission of vibration between the elastic support rod 110 and the cable tie 120 can be slowed down, thereby ensuring the structural stability of the connection between the elastic support rod 110 and the cable tie 120, and at the same time ensuring that no large degree of vibration is transmitted to the user's hand through the cable 400.

[0056] During the production and processing of the first elastic member 130, due to the influence of the processing error, the elastic coefficients of different first elastic members 130 may deviate. In order to ensure that the first elastic members 130 in the assembled multiple take-up assemblies 100 have appropriate elastic force and thus achieve a good shock absorption effect during mass production and assembly, the present application further proposes an implementation method. Please refer to the detailed description. Figure 5 As shown in the figure, a socket hole 1221 is provided at the end of the second socket part 122, and the second socket part 122 is sleeved on the outer periphery of the first socket part 111 through the socket hole 1221. The bottom 123 of the cable tie 120 is provided with a through hole 1231 connected to the socket hole 1221, and the end of the first socket part 111 is provided with a threaded hole 1111. The above-mentioned fastener is a threaded fastener 140, which passes through the through hole 1231 and is connected to the threaded hole 1111, so that when the fitting depth of the threaded fastener 140 and the threaded hole 1111 is adjusted, the distance between the bottom 123 of the cable tie 120 and the top 112 of the elastic support rod 110 changes, thereby changing the compression degree of the first elastic member 130.

[0057] In this embodiment, after the cable tie 120 and the elastic support rod 110 are connected by the threaded fastener 140 arranged along the axial direction, when the elastic coefficient of the matching first elastic member 130 is less than the standard coefficient required for production, it indicates that under the standard compression degree, the elastic force it can generate is less than the standard elastic force. At this time, the depth of the threaded fastener 140 screwed into the threaded hole 1111 can be increased to reduce the distance between the bottom 123 of the cable tie 120 and the top 112 of the elastic support rod 110, and the compression degree of the first elastic member 130 is increased, ensuring that in the assembled state, the first elastic member 130 can still provide an elastic force equal to or relatively close to the standard elastic force, ensuring a reliable shock absorption effect. On the contrary, when the elastic coefficient of the matching first elastic member 130 is greater than the standard coefficient, the elastic force provided by the first elastic member 130 in the assembled state can be reduced by reducing the depth of the threaded fastener 140 screwed into the threaded hole 1111, so that the elastic force is equal to or relatively close to the standard elastic force. Therefore, during the production and assembly process of the wire take-up assembly 100 , the tolerance requirement for the first elastic member 130 can be reduced, thereby reducing the production difficulty and production cost of the first elastic member 130 .

[0058] Furthermore, considering that the cable harness 120 is generally a flat and long structure, it is difficult to insert the threaded fastener 140 from the through hole 1231 inside it, which is not conducive to efficient assembly. In this regard, the present application proposes an implementation method. Figure 5 and Figure 6 , Figure 6 The figure shows the exploded structure of the take-up assembly 100 without the first elastic member 130. As shown in the figure, the cable tie 120 includes a cable tie body 124 and a connecting rod 125. The cable tie hole 121 is formed in the cable tie body 124, and the connecting rod 125 is fixedly connected to the bottom of the cable tie body 124. The connecting rod 125 comprises, from bottom to top, a sleeve section 1251, an abutting section 1252, and a connecting section 1253. The sleeve section 1251 forms the second sleeve portion 122, and the abutting section 1252 has a larger radial dimension than the sleeve section 1251. The bottom of the abutting section 1252 abuts the top of the first elastic member 130, while the connecting section 1253 is sleeved and fixed to the bottom of the cable tie body 124. The through hole 1231 is formed in the abutting section 1252 . The end of the connecting section 1253 is provided with a mounting hole 12531 communicating with the through hole 1231 . The mounting hole 12531 is used for the threaded fastener 140 to enter and penetrate into the through hole 1231 .

[0059] In this embodiment, the cable tie 120 is configured as a cable tie main body 124 and a connecting rod 125. The cable tie main body 124 is responsible for connecting with the cable 400 to erect it, and the connecting rod 125 is responsible for assembling and fixing it to the elastic support rod 110. Specifically, the connecting rod 125 is configured from bottom to top as a sleeve section 1251, an abutment section 1252, and a connecting section 1253. The sleeve section 1251 is used to sleeve with the first sleeve portion 111, the abutment section 1252 is used to abut with the top end of the first elastic member 130 to compress it, and the connecting section 1253 is used to sleeve with the cable tie main body 124 to achieve assembly and fixation of the cable tie main body 124 on the elastic support rod 110. For the installation of the threaded fastener 140, a mounting hole 12531 is opened at the top of the connecting section 1253. Since the length of the connecting section 1253 is much smaller than the overall length of the cable harness 120, the mounting hole 12531 will not be too deep, which makes it convenient to insert the threaded fastener 140 from the mounting hole 12531 and pass it through the through hole 1231 and then connect it with the threaded hole 1111, which is beneficial to improving assembly efficiency.

[0060] For details on how to fix the cable tie body 124 and the connecting section 1253, please refer to Figure 7 As shown in the partial cross-section structure, in some embodiments, the side wall of the bottom of the cable tie body 124 and the side wall of the connecting section 1253 are fixedly connected to each other by a connecting member 150 (such as a pin, screw, etc.). This method not only facilitates assembly operation, but also ensures that the cable tie body 124 and the connecting section 1253 do not rotate relative to each other.

[0061] In order to ensure that the cable 400 has a larger bending radius and avoid excessive bending that affects the stability of the line, the present application further proposes an implementation method. Figure 8 The cable take-up assembly 100 is shown in a state where the cables 400 are erected. As shown in the figure, the cable tie 120 is arc-shaped and smoothly transitions from a vertical extension to a horizontal extension from the bottom to the top. The outlet 1212 of the cable tie hole 121 is opened at the top of the cable tie 120, and the inlet 1211 of the cable tie hole 121 is opened on the side wall of the bottom of the cable tie 120 away from the outlet 1212. The inlet 1211 is used to allow the cable 400 to pass through the cable tie hole 121, and the outlet 1212 is used to allow the cable 400 to pass through the cable tie hole 121.

[0062] It should be noted that the smooth transition from vertical extension to horizontal extension of the cable tie 120 from the bottom to the top does not mean that the bottom of the cable tie 120 must be in an absolutely vertical state, but can also be in an inclined state with a small angle to the vertical direction. Similarly, the top does not have to be in an absolutely horizontal state, but can be as follows: Figure 8 As shown in FIG, it is in a state of being slightly tilted upward, but it can certainly be in a state of being slightly tilted downward.

[0063] from Figure 8 It can be seen that the cable harness 120 is set to an arc shape that smoothly transitions from vertical extension to horizontal extension from the bottom to the top, and the outlet 1212 of the cable harness hole 121 is opened at the top, and the inlet 1211 is opened at the bottom. After the cable 400 passes through the cable harness hole 121, any position on the cable 400 has a large bending radius, and the cable 400 as a whole is in a smooth and uniform bending state, without a bending area with a sharp change in curvature, which is conducive to ensuring the stability of the cable 400.

[0064] Considering that it is difficult to process the cable hole 121 on the cable harness 120, in some embodiments, Figure 9 As shown in the exploded structure of the cable tie 120 , the cable tie 120 includes a first shell 126 and a second shell 127 that are mirror-symmetrical. The first shell 126 and the second shell 127 are fastened to each other.

[0065] exist Figure 9 In the illustrated embodiment, corresponding connecting holes 128 are formed in the first housing 126 and the second housing 127. After the first housing 126 and the second housing 127 are fastened together, fasteners (e.g., rivets, threaded fasteners, etc.) are inserted through the connecting holes 128 in the first and second housings 126, 127 to secure the two. In other embodiments, the first and second housings 126, 127 may also be secured together using a snap-fit connection.

[0066] In this embodiment, by setting the cable tie 120 as two shells that are mirror-symmetrical and interlocked and fixed to each other, the form of opening the cable tie hole 121 on the integrated cable tie is cleverly transformed into the form of grooves respectively opened on two separate structures, thereby facilitating the processing of the cable tie hole 121 on the cable tie 120.

[0067] Considering that the elastic support rod 110 is long, which will cause inconvenience in packaging and transportation, this application proposes an implementation method. Figure 10 The figure shows the exploded structure of the elastic support rod 110. As shown in the figure, the elastic support rod 110 includes a fixing rod 113, a second elastic member 114, and a support rod 115. The bottom of the fixing rod 113 is used for fixed installation relative to the cabinet 200 of the charging pile 500. The second elastic member 114 is fixedly connected between the top of the fixing rod 113 and the bottom of the support rod 115. The top of the support rod 115 is provided with a first socket portion 111.

[0068] Specifically, the fixing rod 113 is responsible for connecting to the cabinet 200 of the charging pile 500, the wall near the charging pile 500, or the ground near the charging pile 500 to secure the entire cable take-up assembly 100 relative to the cabinet 200. The second elastic member 114, which can be a spring, shrapnel, etc., is responsible for the bending and rebound of the cable take-up assembly 100, enabling the cable 400 to be erected and extended horizontally during use. The support rod 115 is responsible for assembling and securing the cable tie 120.

[0069] In this embodiment, the elastic support rod 110 is divided into three parts, specifically the fixing rod 113, the second elastic member 114 and the support rod 115, so as to reduce the length of each component, thereby facilitating the packaging and transportation of the take-up assembly 100.

[0070] exist Figure 10 In the illustrated embodiment, the two ends of the second elastic member 114 are respectively sleeved and fixed to the top of the fixing rod 113 and the bottom of the support rod 115. Furthermore, the three elements can be fixed together by pre-compressing the two ends of the second elastic member 114. Of course, in other embodiments, the three elements can also be fixed together by welding, clamping, or other methods.

[0071] Regarding the structure of the support rod 115, this application further proposes an implementation method. Figure 10 As shown in the figure, the support rod 115 includes a first connecting shaft 1151, a sleeve 1152 and a second connecting shaft 1153. The bottom of the first connecting shaft 1151 penetrates the top of the second elastic member 114 and is fixed, and the top penetrates the bottom end of the sleeve 1152 and is fixed. The side wall in the middle of the first connecting shaft 1151 protrudes outward to form a first abutting block 11511. The bottom of the first abutting block 11511 abuts against the top of the second elastic member 114, and the top abuts against the bottom end of the sleeve 1152. The bottom of the second connecting shaft 1153 penetrates the top of the sleeve 1152 and is fixed, and the top is provided with a first sleeve portion 111. The side wall in the middle of the second connecting shaft 1153 protrudes outward to form a second abutting block 11531. The bottom of the second abutting block 11531 abuts against the top end of the sleeve 1152.

[0072] In this embodiment, by configuring the support rod 115 to be in the form of multiple sections that are interconnected and assembled, the length of each component can be further reduced, making the packaging and transportation of the take-up assembly 100 more convenient.

[0073] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of this application and are not intended to limit them.
