Technical Field
[0001] This utility model relates to the field of charging pile technology, specifically a charging pile that prevents the cable from sticking to the ground during charging. Background Technology
[0002] With the increasing popularity of electric vehicles, charging stations, as an important supporting infrastructure, are widely deployed in various locations. Currently, common charging stations are usually equipped with long charging cables and charging guns to meet the charging needs of vehicles in different parking locations.
[0003] There are two main methods for cable management in existing charging piles: The first is the hanging type, where hooks or slots are installed on the pile. Users need to remove the heavy cable and charging gun from the hooks before use and hang them back afterward. With this method, the cable can easily slip from the user's hand or vehicle during use, drooping directly to the ground. The second is the reel type, where a reel is installed inside or outside the pile for cable retraction. While convenient, when a longer cable is pulled out for charging, the middle section may still droop to the ground due to its own weight or pulling.
[0004] However, charging cables lying flat on the ground present several problems. First, the cables are easily run over by vehicles, stepped on by pedestrians, or rubbed against the ground, leading to damage to the outer sheath and internal wires, posing safety hazards such as leakage and short circuits, and shortening the cable's lifespan. Second, the ground is often covered with dust, mud, oil, and water, and cables lying flat on the ground are easily contaminated, affecting aesthetics and cleanliness. Furthermore, in rainy, snowy, or humid environments, water may seep in through cable joints or damaged areas, causing electrical faults or even safety accidents. This solution only addresses the charging cables in current hanging-type charging piles. To solve the above problems, the inventor proposes a charging pile that prevents cables from lying flat on the ground during charging. Utility Model Content
[0005] In order to solve the problem of charging cables touching the ground when using charging piles, the purpose of this utility model is to provide a charging pile that prevents the cables from touching the ground during charging.
[0006] To solve the above technical problems, this utility model adopts the following technical solution: a charging pile to prevent the charging cable from touching the ground during charging, comprising a pile body, the pile body including a charging cable, one end of the charging cable being electrically connected to a charging gun, the side wall of the charging cable being fitted with an anti-ground contact component, the anti-ground contact component including a first semi-ring and a second semi-ring, the first semi-ring and the second semi-ring corresponding to each other and detachably connected, the arc surfaces of the first semi-ring and the second semi-ring are both provided with heat dissipation grooves, the outer arc surfaces of the first semi-ring and the second semi-ring are both fixedly connected with a protruding cylinder, the cylinder opening of the protruding cylinder is threadedly connected to a stud, the top end of the stud is fixedly connected to a protruding rod, the side wall of the protruding rod is fixedly connected to a cover, the end of the protruding rod facing away from the stud is fixedly connected to a conical shell, and the opening of the conical shell is provided with a ball bearing.
[0007] Preferably, both the first and second semi-rings are fixedly connected to a protruding plate on their end faces. A through hole is provided through the side wall of the protruding plate, and a fastening bolt is provided on one side of the protruding plate. The shank of the fastening bolt passes through the through hole, and a nut is threaded onto the side wall of the fastening bolt. The charging cable and charging gun are existing mature products and are directly selected here. Since they are not the focus of this device, their structure and principle will not be elaborated further. When an anti-grounding component needs to be installed on the charging cable, the first and second semi-rings are fitted onto the charging cable, ensuring the protective pad contacts the outer side wall of the charging cable. Then, the fastening bolt is inserted into the through hole, and the nut engages with the fastening bolt. By tightening the nut, the first and second semi-rings are fixedly installed on the charging cable. Protective pads are fixedly connected to the inner side walls of both the first and second semi-rings. These protective pads can be made of rubber and are used to prevent the charging cable from being damaged during assembly.
[0008] Preferably, one end of the heat dissipation groove extends through the protective pad. During charging with the charging gun, the charging cable generates heat. The heat dissipation groove prevents heat accumulation at the anti-grounding component, avoiding localized overheating and extending the cable's lifespan. The protruding cylinder has an internal thread at its opening, and the stud corresponds to and is threadedly connected to the internal thread. Tightening the protruding rod rotates the stud. When the ball bearing is damaged and needs replacement, the stud separates from the internal thread, allowing the protruding rod to be removed from the protruding cylinder for replacement of the protruding rod, conical shell, and ball bearing. When a new protruding rod, conical shell, and ball bearing need to be installed... During installation, the operation is performed in reverse so that the stud mates with the internal thread to complete the installation. When mates the stud with the internal thread, the bottom surface of the cover must contact the top surface of the protruding cylinder to prevent external dust from entering the connection between the stud and the internal thread, thus avoiding difficulty in turning the stud. There are several protruding cylinders, which are equidistantly distributed and staggered from the heat dissipation groove. The ball bearings can roll inside the conical shell. When the charging cable is pulled to charge through the charging gun, the anti-ground contact component can support the charging cable to prevent it from sticking to the ground, and the ball bearings can reduce the friction between the anti-ground contact component and the ground.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] 1. This utility model can add an anti-grounding component to the existing charging cable to reduce the rectification cost. The anti-grounding component can support the charging cable to prevent it from contacting and sticking to the ground, thereby avoiding direct friction between the charging cable and the ground, greatly extending the service life of the cable, reducing maintenance and replacement costs, and reducing the risk of damage and leakage caused by wear and crushing of the charging cable. It can also prevent sewage from entering the damaged parts of the cable, thereby improving electrical safety and equipment reliability.
[0011] 2. In this utility model, when using a charging gun for charging operations, the heat dissipation groove can prevent the heat generated by the charging cable from accumulating at the anti-grounding component, thereby preventing local overheating at the anti-grounding component installed on the charging cable and thus avoiding affecting the service life of the charging cable.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example: Figure 1-3 As shown, this utility model provides a charging pile that prevents the charging cable from touching the ground during charging. It includes a pile body 1, a charging cable 2, and a charging gun 3 electrically connected to one end of the charging cable 2. An anti-ground contact component 4 is sleeved on the side wall of the charging cable 2. The anti-ground contact component 4 includes a first semi-ring sleeve 5 and a second semi-ring sleeve 6. The first semi-ring sleeve 5 and the second semi-ring sleeve 6 correspond to each other and are detachably connected. Heat dissipation grooves 12 are provided through the arc surfaces of the first semi-ring sleeve 5 and the second semi-ring sleeve 6. A protruding cylinder 13 is fixedly connected to the outer arc surface of the first semi-ring sleeve 5 and the second semi-ring sleeve 6. A stud 16 is threadedly connected to the opening of the protruding cylinder 13. A protruding rod 17 is fixedly connected to the top of the stud 16. A cover 15 is fixedly connected to the side wall of the protruding rod 17. A conical shell 18 is fixedly connected to the end of the protruding rod 17 facing away from the stud 16. A ball bearing 19 is provided inside the opening of the conical shell 18.
[0019] The end faces of the first half-ring 5 and the second half-ring 6 are fixedly connected with protruding plates 8. The side wall of the protruding plate 8 is provided with a through hole 9. A fastening bolt 10 is provided on one side of the protruding plate 8. The shank of the fastening bolt 10 passes through the through hole 9. A nut 11 is threadedly connected to the side wall of the fastening bolt 10.
[0020] By adopting the above technical solution, the charging cable 2 and the charging gun 3 are both existing mature products, which are directly selected here. They are not the focus of this device, so their structure and principle will not be described in detail. When it is necessary to install the anti-grounding component 4 on the charging cable 2, the first half-ring 5 and the second half-ring 6 are fitted on the charging cable 2, and the protective pad 7 is in contact with the outer wall of the charging cable 2. Then, the fastening bolt 10 is inserted into the through hole 9, and the nut 11 is engaged with the fastening bolt 10. By tightening the nut 11, the first half-ring 5 and the second half-ring 6 can be fixedly installed on the charging cable 2.
[0021] Protective pads 7 are fixedly connected to the inner walls of both the first semi-ring 5 and the second semi-ring 6.
[0022] By adopting the above technical solution, the protective pad 7 can be made of rubber material. The protective pad 7 is used to prevent the first half-ring 5 and the second half-ring 6 from damaging the charging cable 2 during assembly.
[0023] One end of the heat dissipation groove 12 extends through the protective pad 7.
[0024] By adopting the above technical solution, when the charging gun 3 is used for charging, the charging cable 2 will get hot. The heat dissipation groove 12 can prevent heat from accumulating at the anti-grounding component 4, thus avoiding local overheating at the anti-grounding component 4 of the charging cable 2 and affecting the service life of the charging cable 2.
[0025] The opening of the protruding cylinder 13 is provided with an internal thread 14, and the stud 16 corresponds to and is threadedly connected to the internal thread 14.
[0026] By adopting the above technical solution, turning the cam 17 can rotate the stud 16. When the ball 19 is damaged and needs to be replaced, the stud 16 can be separated from the internal thread 14, so that the cam 17 can be removed from the cam cylinder 13 for replacement of the cam 17, the conical shell 18, and the ball 19. When installing new cam 17, conical shell 18, and ball 19, the operation is reversed so that the stud 16 engages with the internal thread 14 to complete the installation. When engaging the stud 16 with the internal thread 14, the bottom surface of the cover 15 should contact the top surface of the cam cylinder 13 to prevent external dust from entering the connection between the stud 16 and the internal thread 14 and to avoid making it difficult to turn the stud 16.
[0027] There are several protruding cylinders 13, which are equidistantly distributed and all are offset from the heat dissipation grooves 12.
[0028] By adopting the above technical solution, the ball bearing 19 can roll inside the conical shell 18. When the charging cable 2 is pulled to charge through the charging gun 3, the anti-ground contact component 4 can support the charging cable 2 to prevent the charging cable 2 from sticking to the ground. The ball bearing 19 can also reduce the friction between the anti-ground contact component 4 and the ground.
[0029] Working principle: When using this utility model, when the anti-grounding component 4 is installed on the charging cable 2, the first half-ring sleeve 5 and the second half-ring sleeve 6 are sleeved on the charging cable 2, and the protective pad 7 is in contact with the outer wall of the charging cable 2. Then, the fastening bolt 10 is inserted into the through hole 9, and the nut 11 is engaged with the fastening bolt 10. By tightening the nut 11, the first half-ring sleeve 5 and the second half-ring sleeve 6 can be fixedly installed on the charging cable 2.
[0030] When the charging cable 2 is pulled to charge through the charging gun 3, the anti-ground contact component 4 can support the charging cable 2 to prevent it from sticking to the ground. The ball bearing 19 can reduce the friction between the anti-ground contact component 4 and the ground. When the ball bearing 19 is damaged due to long-term contact with the ground and needs to be replaced, the stud 16 can be separated from the internal thread 14, so that the protruding rod 17 can be removed from the protruding cylinder 13 for replacement of the protruding rod 17, the conical shell 18 and the ball bearing 19. When a new protruding rod 17, conical shell 18 and ball bearing 19 need to be installed, the operation is reversed so that the stud 16 and the internal thread 14 can be engaged to complete the installation.
[0031] Furthermore, when the stud 16 is engaged with the internal thread 14, the bottom surface of the cover 15 must be in contact with the top surface of the protrusion 13 to prevent external dust from entering the connection between the stud 16 and the internal thread 14 and to avoid making it difficult to turn the stud 16.
[0032] When charging is performed using the charging gun 3, the charging cable 2 will generate heat. The heat dissipation groove 12 can prevent heat from accumulating at the anti-grounding component 4, thus preventing local overheating at the anti-grounding component 4 installed on the charging cable 2 and affecting the service life of the charging cable 2.
[0033] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
