Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging pile technology, specifically to a cable protection device and a charging pile. Background Technology
[0002] With the rapid development of new energy vehicles, charging piles have been widely used as supporting infrastructure. Charging cables, as key components for power transmission, require frequent movement and bending during charging, causing the cable sheath to easily rub against and wear down the ground. Especially during dragging, significant friction occurs at the cable's contact point with the ground, which, over time, can damage the cable sheath, affecting insulation performance and lifespan.
[0003] In addition, the torsional force generated when the user operates the charging gun will be transmitted along the charging cable, which can easily cause the cable to spiral and even twist and deform, which not only affects the appearance, but also accelerates the aging of the cable. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a cable protection device and charging pile, which solves the technical problems of existing charging cables being easily damaged by friction with the ground and deformed by twisting and entanglement during use.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] This utility model provides a cable protection device, including a first protective component and a second protective component connected to each other, and a plurality of fasteners. The first protective component includes a first body portion and first flanges respectively disposed at both ends of the first body portion. The second protective component includes a second body portion and second flanges respectively disposed at both ends of the second body portion. Corresponding mounting slots are respectively formed on the first body portion and the second body portion. The first flanges have a plurality of first connecting through holes, and the second flanges have a plurality of second connecting through holes corresponding to the first connecting through holes. The fasteners pass through the first connecting through holes and the second connecting through holes in sequence. The mounting slots are used to accommodate cables.
[0007] In one possible implementation, the first flange is provided with a plurality of positioning grooves, and the first connecting through hole is located at the bottom of the positioning groove.
[0008] In one possible implementation, the first protective element and the second protective element are arranged symmetrically.
[0009] In one possible implementation, the groove wall of the mounting through groove is provided with anti-slip texture.
[0010] In one possible implementation, the first protective element and the second protective element are made of elastic materials.
[0011] This utility model also provides a charging pile, including a charging pile body, a charging cable installed on the charging pile body, and the aforementioned cable protection device. The first protective member and the second protective member are sleeved on the charging cable, and the charging cable is located within the mounting groove.
[0012] In one possible implementation, the cable protection device is multiple.
[0013] The beneficial effects of this utility model are that, compared with the prior art, this utility model uses a through groove to wrap the cable and restrict its displacement, and uses the connecting through hole on the flange to achieve adjustable fixation of the protective component. This simplifies the installation process, effectively disperses the impact of external forces on the cable, prevents wear on the cable sheath and deformation of the internal structure, and solves the technical problems of existing charging cables being easily damaged by friction with the ground and deformed by twisting and entanglement during use.

[0020] To solve the above-mentioned technical problems, this utility model provides a cable protection device and a charging pile. The technical solution and embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0021] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection" and "joining" should be interpreted broadly, for example, they can refer to fixed connection, detachable connection, or integral connection; for those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.
[0023] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0024] In traditional charging pile cable protection technologies, the cable's dragging section directly contacts the ground, causing wear on the outer sheath. Frequent dragging accelerates mechanical damage to the outer insulation layer. Simultaneously, the torque generated when the user operates the charging head is transmitted axially along the cable, causing spiral deformation. During charging pile operation, the cable must withstand repeated tensile loads and torsional torques. Existing protection structures cannot simultaneously provide wear-resistant support and torque dispersion, significantly increasing the risk of fatigue fracture of the cable's internal conductors.
[0025] If the above issues are not addressed, wear on the cable sheath will lead to insulation failure, increasing the risk of leakage; deformation of the conductor stranding structure will reduce current carrying capacity, and when the temperature rise exceeds the material's tolerance limit, it will trigger the fuse protection mechanism. Frequent cable replacements will significantly increase maintenance costs, and a decline in charging pile availability will directly affect the operational efficiency of the charging network. Mechanical stress concentration caused by helical deformation may cause cracking of the connector at the cable root, further leading to charging interruption accidents.
[0026] like Figures 1 to 3As shown, this utility model provides a cable protection device 1, including a first protective member 11 and a second protective member 12 connected to each other, and a plurality of fasteners 13. The first protective member 11 includes a first body portion 111 and first flanges 112 respectively disposed at both ends of the first body portion 111. The second protective member 12 includes a second body portion 121 and second flanges 122 respectively disposed at both ends of the second body portion 121. The first body portion 111 and the second body portion 121 are respectively provided with corresponding mounting slots 14. The first flanges 112 are provided with a plurality of first connecting through holes 113, and the second flanges 122 are provided with a plurality of second connecting through holes 123 corresponding to the first connecting through holes 113. The fasteners 13 pass through the first connecting through holes 113 and the second connecting through holes 123 in sequence, and the mounting slots 14 are used to accommodate cables.
[0027] The first protective component 11 and the second protective component 12, which are interconnected, are two detachable and independently formed parts. They are fixedly connected by fasteners 13 to form a ring structure to wrap the cable. The detachable design facilitates the installation and removal of the cable while ensuring the tightness of the wrapping.
[0028] The first body part 111 and the second body part 121 refer to the main body parts of the first protective member 11 and the second protective member 12, respectively. They adopt a long strip or arc-shaped structure and extend along the length direction to cover the surface of the cable. The shape of the body part matches the outer contour of the cable to disperse external pressure and reduce local stress of the cable.
[0029] The mounting slot 14 refers to a groove or channel formed on the first body part 111 and the second body part 121. Its size is adapted to the diameter of the cable and is used to limit the displacement of the cable in the horizontal and vertical directions to prevent the cable from being pulled away from the protection device.
[0030] The first flange 112 and the second flange 122 refer to the extension structures located at both ends of the first body portion 111 and the second body portion 121, respectively. The flanges extend outward to form a connection platform, thereby increasing the contact area and improving the connection stability, and preventing the fastener 13 from directly pressing the cable.
[0031] The first connecting through hole 113 and the second connecting through hole 123 are holes that penetrate the flange. They are arranged at equal intervals and the two protective parts are detachably fixed by mechanical connectors such as bolts or rivets. The multi-hole design allows the connection position to be adjusted according to the cable size to accommodate cables of different specifications.
[0032] Fastener 13 refers to a metal bolt that passes through the first connecting through hole 113 and the second connecting through hole 123 to lock the two protective components, forming a closed ring-shaped protective structure. This mechanical constraint counteracts the dragging and torsion of the cable by external forces.
[0033] In operation, the cable is placed within the mounting slots 14 of the first body portion 111 and the second body portion 121. The first protective element 11 and the second protective element 12 are then connected and secured using fasteners 13, forming a closed protective structure. The mounting slots 14 provide a protective space for the cable, preventing direct contact with the outside environment. The flange structure increases the strength of the protective device and provides support for the connection. The multiple fasteners 13 ensure the robustness and reliability of the connection.
[0034] The cable protection device 1 effectively protects cables from external abrasion and damage, extending their service life. Its modular design facilitates installation and maintenance, making it suitable for cable protection needs in various scenarios. The flanged connection structure enhances overall strength while providing some adjustment space to accommodate cables of different specifications. The mounting slot 14 protects the cable without affecting its bending performance. Multi-point connection ensures the stability and reliability of the protection device.
[0035] See Figure 1 Furthermore, a plurality of positioning grooves 114 are provided on the first flange 112, and the first connecting through hole 113 is located at the bottom of the positioning groove 114.
[0036] The positioning groove 114 is a recessed structure penetrating the first flange 112, with its bottom plane forming a stepped transition with the surface of the first flange 112. The depth of the positioning groove 114 is greater than or equal to the thickness of the fastener head 13, allowing the fastener head 13 to be completely embedded below the bottom plane of the groove. The first connecting through hole 113 extends axially along the positioning groove 114, with its central axis coinciding with the central axis of the positioning groove 114. The cross-sectional shape of the positioning groove 114 includes semi-circular, rectangular, or trapezoidal shapes, with the semi-circular structure facilitating machining by turning.
[0037] Specifically, during installation, the head of the fastener 13 first embeds into the positioning groove 114, and the sidewall of the positioning groove 114 restricts the radial displacement of the fastener 13. The bottom plane of the groove provides an axial support surface for the fastener 13, preventing the fastener 13 from tilting during tightening. The first connecting through hole 113 is coaxially arranged with the positioning groove 114, ensuring that the shank of the fastener 13 passes vertically through the connecting through hole. When the second connecting through hole 123 of the second flange 122 aligns with the first connecting through hole 113, the guiding effect of the positioning groove 114 causes the second connecting through hole 123 to automatically align. After the fastener 13 is tightened, its head is completely sunk into the positioning groove 114, avoiding external interference caused by the protruding structure. The stepped structure of the positioning groove 114 forms a limiting step to prevent the fastener 13 from axially shifting under vibration.
[0038] The positioning groove 114 accommodates the head of the fastener 13, preventing the fastener 13 from protruding from the surface of the first flange 112 and avoiding collisions with external objects. Simultaneously, the positioning groove 114 limits the position of the fastener 13, preventing it from loosening and falling off during use, thus improving the stability and reliability of the cable protection device 1. Furthermore, the positioning groove 114 facilitates quick location of the first connecting through hole 113 by the operator, improving assembly efficiency.
[0039] In one alternative embodiment, the first protective member 11 and the second protective member 12 are symmetrically arranged.
[0040] The first protective component 11 and the second protective component 12 adopt a mirror-symmetrical geometric structure. Their body cross-sectional shapes and dimensions are identical, and the thickness and width parameters of their flanges are consistent. The mounting slots 14 are correspondingly distributed along the axis of symmetry on the two protective components, and the spacing and diameter of the connecting through holes on the flanges are perfectly matched. The assembly contact surfaces of the two protective components form complementary curved surface structures, and the fasteners 13 are equidistantly inserted through the symmetrically distributed connecting through holes.
[0041] Specifically, the symmetrical structure allows the first protective element 11 and the second protective element 12 to align naturally during assembly, with the symmetrical curved surfaces of the main body forming a closed cylindrical channel. When the fastener 13 passes through the symmetrically arranged connecting through holes, the contact pressure of the two flanges is evenly distributed on both sides of the symmetrical axis, avoiding stress concentration on one side. The symmetrically designed mounting slot 14 forms a complete circular cross-section after closing, creating an equidistant clearance fit with the outer diameter of the cable.
[0042] The symmetrical arrangement of the first protective component 11 and the second protective component 12 simplifies the manufacturing process and reduces production costs. Simultaneously, the symmetrical arrangement makes assembly more convenient and faster, improving installation efficiency. Furthermore, the symmetrical structure enhances the overall stability and balance of the cable protection device 1, making it more reliable during use.
[0043] Optionally, the groove wall of the mounting groove 14 is provided with anti-slip texture (not shown in the figure).
[0044] The anti-slip texture is formed on the surface of the groove wall through a specific structural design. The texture includes evenly spaced raised stripes, recessed grooves, or an interlaced grid structure. The material of the groove wall is the same as the base material of the mounting groove 14, or it is a wear-resistant material layer combined with the base material.
[0045] Specifically, the anti-slip texture increases the roughness of the channel wall surface, generating greater frictional resistance when the cable contacts the channel wall, thus limiting cable slippage within the channel. When the cable is subjected to drag, the raised or recessed structure of the texture disperses the cable's tendency to move through physical obstruction. The uniform distribution of the texture ensures balanced force on the cable along the circumference, avoiding localized stress concentration that could damage the cable sheath. The dimensional parameters of the texture are optimized to provide sufficient friction while avoiding excessively deep or dense textures that could hinder smooth cable installation. The choice of channel wall material further ensures the durability of the texture structure, preventing wear and tear from long-term friction.
[0046] The anti-slip texture increases the friction between the cable and the inner wall of the mounting groove 14, effectively preventing the cable from sliding or shifting within the groove. This improves the stability and reliability of the cable protection device 1, ensuring the cable remains in a fixed position during use and preventing wear or damage caused by cable movement. Furthermore, the anti-slip texture also increases the surface area of the mounting groove 14, which is beneficial for heat dissipation and extends the cable's service life.
[0047] Specifically, the first protective element 11 and the second protective element 12 are made of elastic materials. Preferably, the first protective element 11 and the second protective element 12 can be made of polyurethane material, which has excellent elasticity, wear resistance and anti-aging properties.
[0048] The use of elastic materials allows the protective components to fit snugly against the cable surface, providing comprehensive protection. Simultaneously, the cushioning effect of the elastic material reduces direct impact from external forces on the cable, extending its lifespan. Furthermore, the flexibility of the elastic material makes the protective device easy to install and remove, improving its practicality.
[0049] like Figure 1 and Figure 4 As shown, this utility model also provides a charging pile 2, including a charging pile 2 body, a charging cable 22 installed on the charging pile 2 body, and the aforementioned cable protection device 1. A first protective member 11 and a second protective member 12 are sleeved on the charging cable 22, and the charging cable 22 is located within the mounting groove 14. Further, there are multiple cable protection devices 1.
[0050] Specifically, multiple cable protection devices 1 are arranged at intervals along the section of the charging cable 22 that is dragging on the ground. The first flange 112 and the second flange 122 of each cable protection device 1 are fixed by fasteners 13, forming an independent locking unit. The mounting groove 14 wraps around the charging cable 22. The protective parts made of elastic material undergo radial contraction under the pressure of the fasteners 13, tightly fitting against the cable surface. The spaced cable protection devices 1 can disperse the concentrated effect of dragging force on the cable, reducing the risk of single-point wear. When the charging cable 22 is dragged by an external force, the multiple cable protection devices 1 roll synchronously with the cable, and the segmented support counteracts the transmission of torsional torque, preventing the cable from tangling between adjacent protection devices. The wear resistance of the elastic material reduces frictional loss when the protection devices are in contact with the ground, extending their service life.
[0051] The above design not only extends the service life of the charging cable 22 but also improves the safety of the charging process. Meanwhile, the cable protection device 1 has a simple structure and is easy to install. The specific number and installation location of the cable protection device 1 can be flexibly adjusted according to actual needs, making it suitable for various charging pile 2 application scenarios.
[0052] The above description is merely a preferred embodiment of the present utility model, and the specific embodiments described above are not intended to limit the present utility model. Various modifications and variations can be made within the scope of the technical concept of the present utility model. All refinements, modifications, or equivalent substitutions made by those skilled in the art based on the above description are within the scope of protection of the present utility model.
