Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically to a charging pile charging cable winding mechanism. Background Technology

[0002] Home and public charging stations are usually equipped with long charging cables; however, if long cables are dragged on the ground when not in use, they not only affect the aesthetics of the station, but are also more likely to be run over by vehicles and trampled by pedestrians, causing wear on the cable sheath and damage to the internal wires, posing serious safety hazards and greatly shortening the cable's lifespan.

[0003] To address the aforementioned issues, an active cable retraction mechanism has emerged in the prior art. This mechanism utilizes elastic elements such as clock springs as power sources and pulls the charging cable away from the ground via a dedicated pull rope.

[0004] However, the pull cord is usually rigidly connected to the charging cable through structural components. Large and frequent pulling forces will act directly on the inside of the winding mechanism through the pull cord, which can easily cause overload and damage to core components such as the spring and reel. At the same time, the pull cord must continuously follow the cable, which not only requires overcoming the rebound force provided by the spring, but also the pull cord and cable may become entangled and interfere with each other, making it inconvenient to use. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a charging cable winding mechanism for charging piles, so as to solve the problem of inconvenience in the use of traditional winding mechanisms in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The charging cable winding mechanism for the charging pile includes:

[0008] The rack is equipped with a hanging arm;

[0009] The clamping structure includes a clamping assembly and a hanging ring connected to each other. The clamping assembly is provided with a clamping opening and clamps the charging cable through the clamping opening. The hanging ring is hung on the hanging arm and is configured to detach from the hanging arm by pulling the charging cable.

[0010] Furthermore, the clamping assembly includes: a wire clamp and a fixing clamp. The wire clamp is provided in two and is arranged opposite to each other to form the clamping opening. The fixing clamp is provided with a surrounding space for the two wire clamps to pass through, so as to surround the outer periphery of the clamping wire clamp.

[0011] Furthermore, the wire clamp is provided with a first protrusion and a second protrusion at opposite ends. The first protrusion and the second protrusion extend away from the clamping opening and form a fixing opening with the outer periphery of the wire clamp to position the fixing clamp.

[0012] Furthermore, the fixing clip includes a first fixing part and a second fixing part, one end of the first fixing part is hinged to one end of the second fixing part, and the other ends of the two parts respectively form a first connecting ear and a second connecting ear, and the first connecting ear and the second connecting ear are detachably connected by fasteners.

[0013] Furthermore, the fastener is fitted with a rotating block, which can rotate relative to the fastener and is connected to the hanging ring.

[0014] Furthermore, the hanging ring can rotate relative to the rotating block; or, the hanging ring is fixedly connected to the rotating block.

[0015] Furthermore, a rubber sleeve is provided inside the clamping port to compensate for the gap between the clamping port and the charging cable.

[0016] Furthermore, the rubber sleeve is a detachable, separate structure.

[0017] Furthermore, the hanger is provided with a stop block, which can swing relative to the hanger along a swing axis, and the hanging arm is located below the stop block.

[0018] Compared with the prior art, this utility model has the following advantages: the bracket is installed at the charging pile, the clamping component is used to clamp the charging cable at the corresponding position, and the cable can be hung on the hanging arm through the hanging ring, so that at least one section of the charging cable can be stably suspended in the air, achieving the purpose of quick cable retraction and preventing the charging cable from hanging randomly on the ground or leaning against the vehicle body; furthermore, when charging, only the charging cable needs to be pulled outward to make the hanging ring quickly detach from the hanging arm, eliminating the pull rope connecting the charging cable, making the structure simpler, the operation more convenient, and avoiding spatial interference with the charging cable.

[0027] The present invention will be further described in detail below through specific embodiments:

[0028] In the embodiments of this utility model, such as Figure 1 As shown, the charging cable winding mechanism of the charging pile includes: a hanging frame 1 and a clamping structure; the hanging frame 1 is provided with a hanging arm 2; the clamping structure includes a clamping component 3 and a hanging ring 4 connected to each other, the clamping component 3 is provided with a clamping opening 301, and clamps the charging cable outside through the clamping opening 301, the hanging ring 4 is hung on the hanging arm 2, and is configured to detach the hanging ring 4 from the hanging arm 2 by pulling the charging cable.

[0029] Specifically, in this embodiment of the invention, the mounting bracket 1 is installed on the front or side of the charging pile, and has a hanging arm 2 for hanging the hanging ring 4 on the clamping structure. The clamping component 3 forms a clamping opening 301, which can firmly hold the outer surface of the charging cable and is connected to the hanging ring 4. By hanging the hanging ring 4 on the hanging arm 2, the charging cable can be lifted off the ground, achieving suspended storage. The suspended cable can avoid becoming a ground obstacle, effectively preventing it from being run over by vehicles or stepped on by pedestrians, reducing the risk of damage. At the same time, the cable winding method using the hanging ring 4 is simple to operate, highly repeatable, and does not require reliance on traditional winding methods, nor does it require the hanging arm 2 to be designed to be too large. Of course, the position and number of clamping components 3 can be adaptively adjusted according to the actual length of the cable to improve applicability.

[0030] During cable laying, since the hanging ring 4 is directly suspended from the hanging arm 2 without any additional obstruction, pulling the cable outward will cause the hanging ring 4 to detach from the hanging arm 2, achieving rapid cable laying. This process does not require the use of traction components such as pull ropes, nor does it require overcoming the rebound force of the spring mechanism. The overall structure is more simplified, reducing maintenance costs, avoiding spatial interference, and making operation more convenient.

[0031] like Figures 1-5 As shown, in one embodiment, the clamping assembly 3 includes: a wire clamp 302 and a fixing clamp 306. The wire clamp 302 is provided in two and is arranged opposite to each other to form the clamping opening 301. The fixing clamp 306 is provided with a surrounding space 307 for the two wire clamps 302 to pass through, so as to surround and clamp the outer periphery of the wire clamp 302.

[0032] Specifically, to facilitate gripping and holding the outer surface of the cable, the clamping assembly 3 in this embodiment includes two wire clamps 302 and a fixing clamp 306. The two wire clamps 302 have a semi-circular structure, which are spliced ​​together to form a clamping opening 301 and are arranged around the cable. To fix the two wire clamps 302 to each other, the fixing clamp 306 is provided with a surrounding space 307, so that both wire clamps 302 and the cable can be located within the surrounding space 307, and the fixing clamp 306 surrounds the outer periphery of the clamping wire clamps 302. In this way, the two opposing wire clamps 302 form a hugging contact with the cable surface, and the fixing clamp 306 surrounds and binds its outer periphery, so that the clamping force can be evenly distributed on the cable. Of course, the shape and size of the two wire clamps 302 are not unique, so the size of the clamping opening 301 formed between them is not fixed. By adjusting the tightness of the fixing clamp 306 or selecting different elastic wire clamp 302 materials, it can be adapted to cables with different diameters or slightly different thicknesses within a certain range, improving the versatility of the component.

[0033] Furthermore, such as Figures 3-5 As shown, in one embodiment, the wire clamp 302 has a first protrusion 303 and a second protrusion 304 at its opposite ends. The first protrusion 303 and the second protrusion 304 extend away from the clamping opening 301 and form a fixing opening 305 with the outer periphery of the wire clamp 302 to position the fixing clamp 306. Specifically, the first protrusion 303 and the second protrusion 304 form a physical barrier in the axial direction of the wire clamp 302. The fixing opening 305 formed therebetween allows the fixing clamp 306 to be precisely restricted to the position of the fixing opening 305, effectively preventing sliding or displacement along the surface of the wire clamp 302 when in use or when the cable is pulled. This ensures the binding force of the fixing clamp 306 on the two wire clamps 302 and avoids the risk of decreased clamping force and cable loosening caused by the slippage of the fixing clamp 306. In addition, the fixing opening 305 is designed to prevent mistaken insertion, so that the fixing clamp 306 can be quickly and accurately installed in the designated position, reducing the installation error rate.

[0034] like Figure 3 , Figure 4As shown, in one embodiment, the fixing clip 306 includes a first fixing part and a second fixing part. One end of the first fixing part is hinged to one end of the second fixing part, and the other ends of both form a first connecting ear 308 and a second connecting ear 309, respectively. The first connecting ear 308 and the second connecting ear 309 are detachably connected by fasteners 5. Specifically, in order to hold the two wire clamps 302 tightly, the fixing clip 306 in this embodiment is designed as a clamp structure, that is, the hinged part allows the fixing clip 306 to be easily opened like a clamp and fitted onto the outer periphery of the wire clamp 302 already installed on the cable, and then closed, which is convenient and quick to operate. At the same time, by connecting the first connecting ear 308 and the second connecting ear 309 with fasteners 5 (such as bolts or screws), the tightness of the fixing clip 306 can be adjusted. By adjusting the tightness of the fasteners 5, the clamping force can be finely adjusted to ensure that the wire clamp 302 and the cable are firmly locked, while avoiding damage to the wire clamp 302 or the cable due to excessive clamping force. Of course, it can also improve the versatility and applicability of components.

[0035] like Figures 1-3 As shown, in one embodiment, the fastener 5 is fitted with a rotating block 6, which can rotate relative to the fastener 5 and is connected to the hanging ring 4. Specifically, when the cable is pulled, the cable itself will twist. Without the rotating block 6, this torsional force would be directly transmitted to the hanging ring 4 through the rigid clamping assembly 3, causing additional friction and resistance between the hanging ring 4 and the hanging arm 2, resulting in poor cable release and even the risk of entanglement. The rotating block 6 allows the clamping assembly 3 and the cable to rotate freely relative to the hanging ring 4, so that the pulling force can be fully used to make the hanging ring 4 move smoothly along the hanging arm 2 and disengage. Of course, the rotation direction shown in this embodiment is not unique and can be adjusted adaptively according to different installation positions; for example, the rotating block 6 can rotate around the X-axis, Y-axis, or Z-axis. Preferably, the hanging ring 4 can rotate relative to the rotating block 6 to provide a wider range of rotation angles. Of course, in other embodiments, the hanging ring 4 and the rotating block 6 are fixedly connected to improve the connection strength between the two.

[0036] like Figures 1-4 As shown, in one embodiment, a rubber sleeve 7 is provided inside the clamping opening 301 to compensate for the gap between the clamping opening 301 and the charging cable. Specifically, this increases the static friction between the clamping opening 301 and the cable, ensuring that there is no relative slippage between the clamping component 3 and the cable during normal suspension or even pulling, thereby ensuring the reliability of suspended storage and preventing the cable from sagging due to displacement of the clamping component 3. At the same time, the rubber sleeve 7 acts as a soft pad, converting the rigid clamping force applied by the wire clamp 302 into a uniformly distributed flexible pressure, effectively preventing the cable insulation layer from being crushed, cut, or worn by the wire clamp 302. Preferably, for ease of installation or replacement, the rubber sleeve 7 is a split, detachable structure.

[0037] like Figure 6 As shown, in one embodiment, the hanger 1 is provided with a stop 8, which can swing relative to the hanger 1 along the swing axis A, and the hanging arm 2 is located below the stop 8. Specifically, the stop 8 constitutes a physical obstacle in the path of the hanging ring 4. That is, when the hanging ring 4 is suspended at rest, the stop 8 hangs down naturally under the action of gravity or a slight preload, preventing the hanging ring 4 from slipping off the hanging arm 2 due to wind, vibration or accidental contact, thus improving the reliability of storage; when it is necessary to retrieve the cable, only an outward pulling force needs to be applied, which will push the hanging ring 4 to push open the stop 8, thereby detaching it smoothly. Compared with manually operated buckles or buttons, this swing-type stop 8 achieves automatic unlocking or locking with a push. When retrieving the cable, simply push the hanging ring 4 back, and the stop 8 will be automatically pushed open and reset, the whole process does not require manual operation, making operation more convenient. Figure 5 As shown, in order to accommodate the stop block 8 and allow the hanging ring 4 to detach from the hanging arm 2, the hanging arm 2 is vertically mounted on the hanging frame 1.
