Description

Technical Field

[0001] This utility model relates to the field of automobile charging equipment technology, specifically a charging cable storage device for a charging pile. Background Technology

[0002] New energy vehicle energy-saving charging piles are energy-saving and environmentally friendly devices that can charge various models of electric vehicles according to different voltage levels. The input end of the new energy vehicle energy-saving charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.

[0003] Patent CN220785498U discloses a charging pile with charging cable storage, including a charging pile body, a charging cable mounted on the charging pile body, and a charging head mounted on the charging cable. The charging pile body has a connector that mates with the charging head. A charging cable storage mechanism is provided on the charging pile body corresponding to the connector. The charging cable storage mechanism includes an assembly plate on the charging pile body and limiting members on the assembly plate. The assembly plate has a through hole corresponding to the connector to facilitate the passage of the charging head. Two limiting members are provided above and below the through hole, and each limiting member is vertically slidably mounted on the assembly plate. This technical solution has the advantages of simple structure, ease of use and maintenance, and high reliability.

[0004] However, in the above technical solution, the charging cable cannot be automatically stored after the gun is returned.

This manual process is tedious and can easily cause uneven winding, resulting in the charging cable becoming tangled and knotted. Utility Model Content

[0005] The purpose of this utility model is to provide a charging cable storage device for a charging pile, so as to solve the technical problem mentioned in the background art that the charging cable cannot be automatically stored after the charging gun is returned.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A charging cable storage device for a charging pile includes a charging pile body, in which a U-shaped frame is fixedly installed. An embedding groove is provided on the inner ring wall of the U-shaped frame. An embedding mechanism can slide on the outer surface of the U-shaped frame to press the charging cable of the charging pile body into the embedding groove. The sliding sleeve of the pressing mechanism is installed on the outer surface of the U-shaped frame.

[0008] As a preferred embodiment of this utility model, rubber protrusions are fixedly installed at both ends of the embedding groove, so that the rubber protrusions are squeezed and plastically collapsed before the charging cable is pressed into the embedding groove, and the pressed charging cable is subject to limiting and locking force by the rubber protrusions.

[0009] As a preferred embodiment of this utility model, the pressing mechanism includes two sets of first U-shaped frames and second U-shaped frames. Connecting plates are rotatably installed on both ends of the inner side of the two sets of first U-shaped frames, and the other ends of each pair of vertically opposite connecting plates are rotatably connected. The second U-shaped frame is slidably installed inside the first U-shaped frame, so that the first U-shaped frame and the second U-shaped frame are assembled into a square shape and slidably fitted onto the outer surface of the U-shaped frame.

[0010] As a further preferred embodiment of this utility model, an mounting plate is fixedly installed between the two sets of second U-shaped frames. A motor is fixedly installed at one end of the mounting plate. The output shaft of the motor rotates through the mounting plate and a gear is fixedly installed at its end. The gear meshes with a rack, and the rack is fixedly installed on the outer surface of the U-shaped frame.

[0011] As a further preferred embodiment of this utility model, a connecting groove is provided at one end of the second U-shaped frame that slides into the first U-shaped frame. A spring is provided in the connecting groove, and the two ends of the spring are respectively fixedly connected to one end in the connecting groove and one end in the first U-shaped frame.

[0012] As a further preferred embodiment of this utility model, a roller is rotatably installed between each pair of horizontally opposite connecting plates. The roller rolls in contact with the limiting groove, which is opened at both ends of the inner ring wall of the U-shaped frame. The roller is conical.

[0013] Compared with the prior art, the beneficial effects of the charging cable storage device for a charging pile of this utility model are as follows:

[0014] This invention involves pulling the charging gun to extract the charging cable from the U-shaped frame's recessed slot. During this process, the charging cable is pulled out by compressing the rubber protrusions on both sides of the recess, causing them to collapse inwards and allowing the cable to be pulled out. After use and returning the gun, the charging cable hangs naturally within the U-shaped frame. Then, a pressing mechanism is activated to engage a rack fixed to the outer surface of the U-shaped frame, allowing it to slide along the frame's surface. This presses the naturally hanging charging cable back into the recessed slot, while the cable that has slid to the outside of the U-shaped frame is also... As the rollers press, the charging cable is drawn into the U-shaped frame and pressed in. Before being pressed into the insertion groove, the rubber protrusions are squeezed to cause plastic collapse, so that the pressed charging cable is limited and locked by the rubber protrusions, which can stably fix the charging cable in the insertion groove and prevent the charging cable from accidentally coming out due to shaking or external pulling. This ensures the stability of the storage process. After use and return of the gun, the pressing mechanism and the rack meshing transmission can automatically press the naturally hanging charging cable into the insertion groove, eliminating the need for manual winding, improving storage efficiency and saving manpower and time.

[0023] See Figure 1-2 As shown in the figure, an embodiment of the present invention provides a charging cable storage device for a charging pile, including a U-shaped frame 101 fixedly installed inside the charging pile body 1. An embedding groove 104 is formed on the inner ring wall of the U-shaped frame 101. A pressing mechanism 2 can slide on the outer surface of the U-shaped frame 101 within the embedding groove 104 to press the charging cable 102 of the charging pile body 1 into it. The pressing mechanism 2 is slidably installed on the outer surface of the U-shaped frame 101. Rubber protrusions 103 are fixedly installed at both ends of the embedding groove 104, so that before the charging cable 102 is pressed into the embedding groove 104, the rubber protrusions 103 are squeezed, causing them to plastically collapse, and the pressed-in charging cable 102 is subject to a limiting and locking force by the rubber protrusions 103.

[0024] like Figure 3 As shown, the pressing mechanism 2 includes two sets of first U-shaped frames 201 and second U-shaped frames 202. Both ends of the inner side of the two sets of first U-shaped frames 201 are rotatably mounted with connecting plates 209, and the other ends of each pair of vertically opposite connecting plates 209 are rotatably connected. The second U-shaped frame 202 is slidably installed inside the first U-shaped frame 201, so that the first U-shaped frame 201 and the second U-shaped frame 202 are assembled into a square shape and slidably fitted onto the outer surface of the U-shaped frame 101.

[0025] A mounting plate 203 is fixedly installed between the two sets of second U-shaped frames 202. A motor 204 is fixedly installed at one end of the mounting plate 203. The output shaft of the motor 204 rotates through the mounting plate 203 and a gear 205 is fixedly installed at its end. The gear 205 meshes with a rack 106, which is fixedly installed on the outer surface of the U-shaped frame 101. A connecting groove 206 is provided at one end of the second U-shaped frame 202 that slides into the first U-shaped frame 201. A spring 207 is provided in the connecting groove 206, and the two ends of the spring 207 are fixedly connected to one end in the connecting groove 206 and one end in the first U-shaped frame 201, respectively. A roller 208 is rotatably installed between each pair of transversely opposite connecting plates 209. The roller 208 rolls in the limiting groove 105, which is located at both ends of the inner ring wall of the U-shaped frame 101. The roller 208 is conical.

[0026] After the gun is returned, the motor 204 can be started to drive the gear 205 to mesh with the transmission rack 106. This transmission force can then drive the U-shaped frame 101, which is assembled from the first U-shaped frame 201 and the second U-shaped frame 202, to slide on the outer surface of the U-shaped frame 101. The driven first U-shaped frame 201 can then drive the inner rotating roller 208 to slide in the limiting groove 105 opened on the inner wall of the U-shaped frame 101. This allows the conical roller 208 to press the charging cable 102, which naturally hangs or slides to the outer end of the U-shaped frame 101, into and pull it into the embedding groove 104. After the charging cable 102 is pressed into and stored in the embedding groove 104, the motor 204 can be reversed to its original position to prepare for the next use. The whole process is highly automated, easy to operate, and provides a good user experience.

[0027] During the process of pressing the charging cable 102 into the embedding groove 104 and passing through the U-shaped bend, the roller 208 slides and extends on the outer surface of the first U-shaped frame 201 and the second U-shaped frame 202, and is also tilted at an angle by the connecting plate 209. This ensures that the roller 208 can fully fit into the limiting groove 105 for rolling after passing through the U-shaped bend, ensuring precise rolling of the charging cable 102 in the U-shaped bend section, so that it can smoothly enter the embedding groove 104 and avoid the charging cable 102 from being rolled. The U-shaped bend may cause twisting, tangling, or incomplete retraction. During the retraction process, the spring 207 will be pulled, and the spring 207 will apply a pull force to the second U-shaped frame 202. This allows the roller 208 to press the charging cable 102 in the U-shaped bend into the embedding groove 104 in the U-shaped part through the elastic pressure applied by the spring 207. This can avoid applying excessive rigid pressure to the charging cable 102 and the device, thereby preventing the charging cable 102 from being over-compressed and damaged, and extending its service life.

[0028] According to the above technical solution, in use, the charging cable 102 can be pulled out of the embedding groove 104 of the U-shaped frame 101 by pulling the charging gun. During the process of pulling the charging cable 102 out of the embedding groove 104, the rubber protrusions 103 on both sides of the embedding groove 104 will be squeezed and collapsed inward to allow the charging cable 102 to be pulled out. After use and returning the gun, the charging cable 102 can be allowed to hang naturally in the U-shaped frame 101. Then, the motor 204 can be started to drive the gear 205 to mesh with the transmission rack 106, thereby enabling this transmission force to drive the U-shaped frame formed by the first U-shaped frame 201 and the second U-shaped frame 202 to slide on the outer surface of the U-shaped frame 101. The driven first U-shaped frame 201 can then rotate and install the inner side. The roller 208 slides within the limiting groove 105 on the inner wall of the U-shaped frame 101, thereby enabling the conical roller 208 to press and pull the charging cable 102, which naturally hangs or slides to the outer end of the U-shaped frame 101, into the embedding groove 104. Before the charging cable 102 is pressed into the embedding groove 104, the rubber protrusion 103 is also squeezed to cause it to undergo plastic collapse, so that the pressed charging cable 102 is subject to limiting and locking force by the rubber protrusion 103, so that the charging cable 102 can be stably fixed in the embedding groove 104, preventing the charging cable 102 from accidentally coming out due to shaking or external pulling, and ensuring the stability of the storage process. After the charging cable 102 is pressed into the embedding groove 104, the motor 204 can be reversed back to its original position, ready for the next use.

[0029] During the process of the roller 208 pressing the charging cable 102 into the embedding groove 104 and passing through the U-shaped bend of the U-shaped frame 101, the roller 208 will slide and extend through the first U-shaped frame 201 on the outer surface of the second U-shaped frame 202, and will also tilt at an angle through the connecting plate 209. This ensures that the roller 208 can fully fit into the limiting groove 105 for rolling after passing through the U-shaped bend, ensuring precise rolling of the charging cable 102 in the U-shaped bend section, so that it can smoothly enter the embedding groove 104. During the sliding process, the roller 208 will also pull the spring 207, and the spring 207 will apply a pull force to the second U-shaped frame 202, so that the roller 208 can press the charging cable 102 in the U-shaped bend section into the embedding groove 104 in the U-shaped section through the elastic pressure applied by the spring 207.

[0030] In summary, after the device is used and the gun is returned, the naturally hanging charging cable 102 is pressed back into the embedding groove 104 by the roller 208, eliminating the need for manual winding, thus improving storage efficiency and saving manpower and time.

[0031] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
