Abstract
Description
Technical Field
[0001] This invention relates to the field of charging cable technology, specifically to a flexible, wear-resistant charging cable. Background Technology
[0002] In today's world where electronic devices are widely used, charging cables serve as a crucial bridge between the power source and backup power supply, and their performance directly impacts the user experience and safety of devices. However, existing charging cables generally face problems during long-term use, such as difficulty in balancing flexibility and abrasion resistance, insufficient insulation and anti-static properties, and contradictions between voltage resistance and deformation adaptability, making it difficult to meet the needs of use in complex scenarios.
[0003] The flexible design of existing charging cables often comes at the cost of structural stability. To achieve ease of bending, some cables use excessively flexible outer materials and simple internal structures. This leads to fatigue damage to the internal core wires due to a lack of effective support during frequent bending, especially at the connection between the cable and the charging head. Repeated bending causes premature cracking of the outer material in this area, exposing the internal conductors, which not only affects service life but also poses a risk of electric shock. Furthermore, these cables have weak abrasion resistance; the outer material is prone to wear and thinning or even breakage after prolonged friction with objects such as desktops and floors, further exacerbating damage to the internal structure.
[0004] On the other hand, cables that prioritize abrasion resistance often use rigid outer sheath materials. While these materials can resist external friction to some extent, they severely limit the cable's flexibility. When adjusting the charging angle or storing the cable, the overly rigid material makes bending difficult, resulting in a poor user experience. Furthermore, rigid materials are prone to brittle fracture after repeated bending, making long-term stable use impossible. In addition, the internal pressure-resistant structure of these cables is simple, often relying on a single rigid support. When subjected to external pressure or impact, they cannot effectively buffer stress through deformation, easily causing internal core wire breakage and resulting in charging interruption.
[0005] Regarding insulation and anti-static properties, existing charging cables mostly employ a single-layer insulation design, which offers limited insulation effectiveness. In dry environments or electrostatic-sensitive scenarios, external static electricity can easily be conducted through the cable surface to the interior, interfering with current transmission stability and even damaging connected electronic devices. Simultaneously, the connection between the insulation layer and the internal core wires is not robust enough; during cable movement or deformation, relative slippage can easily occur, leading to localized insulation wear, reduced insulation performance, and increased safety hazards related to current leakage.
[0006] To address the aforementioned issues, there is an urgent need for a charging cable that can balance flexibility and abrasion resistance, enhance insulation and antistatic properties, and coordinate voltage resistance and deformation adaptability, in order to overcome the shortcomings of existing technologies such as short service life, insufficient safety, and limited application scenarios. Summary of the Invention
[0007] The purpose of this invention is to provide a flexible, wear-resistant charging cable to solve the problems existing in the flexibility, wear resistance, safety and pressure resistance of current charging cables.

[0011] Preferably, the surface of the cable core is fitted with an insulating ring to enhance antistatic performance, and the cable core is fixed to the insulating protective layer through the insulating ring; the insulating ring is arranged in several groups, and the groups of insulating rings are distributed at equal intervals, and the insulating ring is made of flexible insulating material; the inner surface of the insulating ring is fixed with several anti-slip protrusions distributed in a ring, and the anti-slip protrusions are in close contact with the surface of the cable core.

[0013] Preferably, the outer surface of the insulating protective layer is fitted with several pairs of pressure-resistant rings corresponding to the first protective section of the cable. The several sets of pressure-resistant rings are distributed at equal intervals, and a pair of pressure-resistant rings are fixedly connected by several sets of rubber shafts. The pressure-resistant rings are circular, and the several sets of rubber shafts are distributed at equal intervals along the circumference between a pair of pressure-resistant rings. The rubber shafts are made of flexible elastic material.
[0014] Preferably, the rubber balls are arranged in several groups, and the rubber balls are positioned in the middle of two adjacent groups of rubber shafts between a pair of pressure-resistant rings; the surfaces of the rubber balls are respectively attached to the inner wall of the wrapping layer and the outer surface of the insulating protective layer, and the rubber balls are made of flexible pressure-resistant material.
[0015] Preferably, the outer surface of the insulating protective layer is connected to a wrapping layer by a number of pressure-resistant rings within the first protected section of the cable, and the wrapping layer is made of a flexible wear-resistant material; the inner surface of the wrapping layer is provided with a number of arc-shaped grooves that are adapted to the rubber ball, and the curvature of the arc-shaped grooves is consistent with the curvature of the surface of the rubber ball.
[0016] Preferably, the inner wall of the first protection section of the cable is fixed with a plurality of sets of silicone flexural strips; the plurality of silicone flexural strips are of the same length as the first protection section of the cable, and the plurality of sets of silicone flexural strips are distributed in a ring at equal intervals, and the silicone flexural strips have high flexibility and high toughness.
[0017] Preferably, the first protection section of the cable is fixed to the outer surface of the wrapping layer by a number of sets of silicone fold-resistant strips, and the first protection section of the cable adopts a flexible wear-resistant outer layer material.
[0018] Compared with the prior art, the beneficial effects of the present invention are: In existing technologies, the insulation structure of charging cables is mostly a single-layer design. With frequent bending, the insulation layer is prone to friction with the core due to repeated stretching, leading to localized wear or thinning. This not only reduces insulation effectiveness but may also pose safety hazards. Furthermore, its anti-static function often relies solely on the properties of the insulation material itself, lacking a dedicated reinforcing structure. In dry environments or other conditions prone to static electricity, it is difficult to effectively resist external static interference. This cable fundamentally solves these problems through a dual protection system formed by an insulating ring and an insulating protective layer. The insulating ring uses a flexible insulating material that can adapt to the bending of the cable. The curved shape allows for a tight fit with the cable core via anti-slip protrusions on the inner side, preventing relative slippage between the two and reducing insulation layer loss due to friction, thus ensuring long-term stability of insulation performance. The insulation protection layer is designed for anti-static requirements, further enhancing the ability to isolate static electricity on the basis of the insulation ring. The dual structure works together to significantly reduce the risk of current fluctuations caused by electrostatic interference and the problem of current leakage caused by insulation failure. Compared with the single-layer protection of existing technologies, it is more adaptable to long-term use in complex environments, especially in charging scenarios of electrostatic-sensitive electronic devices.
[0019] In traditional cable design, it's often difficult to balance pressure resistance and flexibility. Using rigid materials to construct the pressure-resistant frame provides good pressure support but severely limits the cable's bending ability, making it inconvenient for applications requiring frequent bending and even prone to breakage due to excessive rigidity. Conversely, using excessively soft materials for flexibility results in insufficient pressure resistance, making the internal core wires susceptible to damage under external pressure or impact. This cable achieves a perfect synergy between these two aspects through a unique structural design: the rigid frame formed by the pressure-resistant rings provides stable support for the cable's internal structure, ensuring the overall pressure resistance; while the rubber shafts connecting adjacent pressure-resistant rings... Using flexible and elastic materials, it can adapt to the bending of the cable, neither hindering the bending action nor hindering the cable. It can also quickly recover its original shape after deformation due to its own elasticity, reducing structural damage caused by repeated deformation. In addition, the rubber balls between adjacent rubber shafts further play a buffering role, absorbing the stress generated by deformation through their own compression or rolling, avoiding damage to local areas due to excessive force. Compared with the problem of mutual constraints between flexibility and pressure resistance in existing technologies, it performs better in scenarios such as frequent bending and compression. It can not only maintain good flexibility to adapt to various usage requirements, but also provide reliable pressure resistance protection, significantly reducing the damage rate of the cable and extending its service life.
[0020] Existing cable abrasion-resistant designs mostly employ a single, integral abrasion-resistant layer. The connection between the cable and the charging head, due to frequent plugging and unplugging, undergoes repeated bending, making it a high-risk area for wear. Long-term contact and friction with surfaces like desktops and floors during cable placement also easily leads to localized wear. Traditional integral abrasion-resistant layers cannot reinforce these areas, often resulting in damage to these high-frequency wear zones first, ultimately rendering the entire cable unusable. This cable adopts a differentiated protection strategy, designing specialized protective structures for different areas based on their wear characteristics: the abrasion-resistant wrapping layer on the outer surface of the first protective section of the cable specifically addresses direct friction between this area and external objects; the upper and lower wrapping layers of the second protective section... The two layers work together to fully cover the surface of the cable section, preventing wear caused by contact with different objects. The wear-resistant blocks distributed in a matrix on the surface of the lower sheath layer further enhance the wear resistance when the cable is in contact with the placement surface, reducing bottom loss caused by long-term placement. The protective sleeve is specifically designed to protect the connection between the cable charging head and the first protected section of the cable, effectively resisting bending and friction during insertion and removal. Compared with the existing integrated design, this protective design can more rationally distribute the wear-resistant material to the most needed parts. While ensuring the overall protection effect, it greatly improves the durability of key wear areas, avoids the situation where the entire cable is scrapped due to local wear, and extends the actual service life of the cable.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] Please see Figures 1-8 As shown, the present invention provides a technical solution: a flexible wear-resistant charging cable, comprising: a cable core 1 and a silicone fold-resistant strip 16; Several sets of equidistant insulating rings 11 are fitted on the surface of the cable core 1. The insulating rings 11 are made of flexible insulating material and have annular anti-slip protrusions on their inner surface, which fit tightly against the cable core 1. The cable core 1 is fixed to the insulating protective layer 10 through the insulating rings 11. The insulating protective layer 10 enhances the anti-static effect. Several pairs of equidistant pressure-resistant rings 13 are fitted on the outside of the insulating protective layer 10 corresponding to the first protection section 2 of the cable. A pair of pressure-resistant rings 13 are fixed to each other through annularly distributed flexible elastic rubber shafts 14. There are flexible pressure-resistant rubber balls 15 between adjacent rubber shafts 14. Their surfaces are respectively attached to the inner walls of the insulating protective layer 10 and the wrapping layer 12. The wrapping layer 12 is made of flexible wear-resistant material and has an arc-shaped groove on its inner surface that matches the rubber ball 15. It is fixed to the insulating protective layer 10 through the pressure-resistant rings 13.
[0025] The first protection section 2 of the cable adopts a flexible and wear-resistant outer layer material. Several sets of silicone folding resistance strips 16, which are equal in length to the section and distributed in a ring at equal intervals, are fixed on the inner wall. The silicone folding resistance strips 16 have high flexibility and high toughness. The first protection section 2 of the cable is fixed to the wrapping layer 12 through the silicone folding resistance strips 16. The outer surface is covered with a wear-resistant wrapping layer 4, and one end is covered with a cable charging head 3 that is fixed to the main core 1 of the cable. A protective sleeve 17 is covered at the connection between the two. The inner wall of the protective sleeve 17 is tightly fitted to the outer surface of the first protection section 2 of the cable and the cable charging head 3.
[0026] The upper surface of the second protection section 9 of the cable is covered with an upper wrapping layer 5 that has the same function as the anti-wear wrapping layer 4, and the lower surface is provided with wear-resistant components. The wear-resistant components include a lower wrapping layer 7 and a matrix of wear-resistant blocks 8. The lower wrapping layer 7 is covered with the lower surface of the second protection section 9 of the cable, and the wear-resistant blocks 8 are fixed on the surface of the lower wrapping layer 7. The upper wrapping layer 5 and the lower wrapping layer 7 are symmetrically distributed in a half-circle shape and are both made of flexible wear-resistant materials.
[0027] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the wear-resistant component includes a cable core 1 and a silicone folding-resistant strip 16. The first protection section 2 and the second protection section 9 of the cable are wrapped around the cable core 1 and fixedly connected by a connecting sheath 6.
[0028] Several sets of equidistant insulating rings 11 are fitted on the surface of the cable core 1. These rings are made of flexible insulating material and have annular anti-slip protrusions on their inner surface that fit tightly against the core. The core is connected to the insulating protective layer 10 through the insulating rings 11 to enhance anti-static properties. Several pairs of equidistant pressure-resistant rings 13 are fitted on the insulating protective layer 10 at the first protected section 2 of the cable. A pair of pressure-resistant rings 13 are fixedly connected by annular equidistant flexible elastic rubber shafts 14. There are flexible pressure-resistant rubber balls 15 between adjacent rubber shafts 14, which fit against the inner wall of the insulating protective layer 10 and the wrapping layer 12. The wrapping layer 12 is made of flexible wear-resistant material and has arc-shaped grooves on its inner surface that fit the rubber balls 15. It is also fixedly connected to the insulating protective layer 10 through the pressure-resistant rings 13.
[0029] Furthermore, the first protective section 2 of the cable is made of flexible wear-resistant material, and several sets of highly flexible and tough silicone fold-resistant strips 16 with the same length and equidistant rings as the section are fixed on the inner wall, and are fixed to the wrapping layer 12 through them. The outer surface is covered with a wear-resistant wrapping layer 4, one end of which is connected to the cable charging head 3, and a protective sleeve 17 is covered at the connection. The inner wall of the protective sleeve 17 is tightly attached to the outer surfaces of both.
[0030] Furthermore, the wear-resistant components of the second protection section 9 of the cable consist of a lower wrapping layer 7 and wear-resistant blocks 8. The lower wrapping layer 7 is fitted onto the lower surface of the second protection section 9 of the cable, and several sets of wear-resistant blocks 8 are fixed on its surface, arranged in a matrix. The upper surface of the second protection section 9 of the cable is fitted with an upper wrapping layer 5, which has the same function as the wear-resistant wrapping layer 4. The upper wrapping layer 5 and the lower wrapping layer 7 are symmetrically arranged on the surface of the second protection section 9 of the cable, both being half-ring shapes, and both are made of flexible wear-resistant material, together forming comprehensive wear-resistant protection for the second protection section 9 of the cable.
[0031] according to Figure 5 , Figure 7 and Figure 8 As shown, the insulating ring 11 is made of flexible insulating material, and several groups of them are distributed at equal intervals on the surface of the cable core 1. Several annular anti-slip protrusions are fixed on the inner surface, which are tightly attached to the surface of the cable core 1. The cable core 1 is fixed to the insulating protective layer 10 through the insulating ring 11. The insulating protective layer 10 enhances the antistatic effect. The two work together to enhance the protection and antistatic performance of the cable core 1. Furthermore, the wrapping layer 12 is made of flexible wear-resistant material and is fixed to the outer surface of the insulation protection layer 10 corresponding to the first protection section 2 of the cable through several sets of pressure-resistant rings 13. A rubber ball 15 is provided between its inner wall and the outer surface of the insulation protection layer 10, and an arc-shaped groove adapted to the rubber ball 15 is opened on the inner surface.
[0032] Furthermore, the silicone flexural strips 16 have high flexibility and high toughness. Several groups of them are fixed to the inner wall of the first protection section 2 of the cable, with the same length as the first protection section 2 of the cable and distributed in a ring at equal intervals. The first protection section 2 of the cable is fixed to the outer surface of the wrapping layer 12 through these silicone flexural strips 16, which not only increases the tensile strength of the first protection section 2 of the cable, but also improves its flexibility, and at the same time achieves a stable connection with the wrapping layer 12.
[0033] Furthermore, the insulating ring 11 connects the main core 1 of the cable to the insulating protective layer 10, the wrapping layer 12 is connected to the insulating protective layer 10, and the silicone folding strip 16 fixes the first protective section 2 of the cable to the wrapping layer 12. All components work closely together to ensure the cable's protection, flexibility and other performance.
[0034] according to Figure 6 As shown, the pressure-resistant ring 13 is circular in shape, and several groups are distributed at equal intervals and sleeved on the outer surface of the insulation protection layer 10 corresponding to the first protection section 2 of the cable. It is the core frame component that constitutes the cable pressure-resistant structure.
[0035] Furthermore, a pair of pressure-resistant rings 13 are fixedly connected by several sets of rubber shafts 14. The rubber shafts 14 are made of flexible elastic material and are distributed in a ring at equal intervals between the pair of pressure-resistant rings 13. This not only achieves a stable connection between the pressure-resistant rings 13, but also provides elastic buffer for the overall structure due to their own flexible elasticity, ensuring pressure resistance without affecting the flexibility of the cable. The rubber balls 15 are made of flexible pressure-resistant material and are arranged in several sets. Each set is located in the middle of two adjacent sets of rubber shafts 14 between the pair of pressure-resistant rings 13. Their surfaces are closely attached to the inner wall of the wrapping layer 12 and the outer surface of the insulating protective layer 10, respectively, and are adapted to the arc-shaped groove of the inner wall of the wrapping layer 12. They form supplementary support in the gaps of the frame formed by the rubber shafts 14, further enhancing the pressure resistance of the overall structure, while improving the cooperative fit with the surrounding components.
[0036] Furthermore, the pressure-resistant ring 13 forms the basic pressure-resistant frame, the rubber shaft 14 provides elastic connection and support, and the rubber ball 15 fills the gaps to enhance pressure resistance. Together, they significantly improve the pressure resistance performance of cable A while ensuring the flexibility of the cable.
[0037] The overall effect achieved by the organization is as follows: In terms of insulation and anti-static protection, the insulating ring 11 and the insulating protective layer 10 outside the cable core 1 form a dual protection system. The insulating ring 11 is made of flexible insulating material, possessing insulating properties and adapting to the bending and folding of the cable. Its inner annular anti-slip protrusions fit tightly against the surface of the cable core 1, fixing the position of the insulating ring 11 and preventing relative sliding between the insulating ring 11 and the core during frequent cable movement or deformation, thus ensuring the stability of the insulation effect. At the same time, the insulating rings 11 are evenly spaced, reducing the restriction on cable flexibility while ensuring insulation performance, allowing the cable to cope with various bending scenarios.
[0038] The insulating protective layer 10 enhances the anti-static effect based on the insulating ring 11. It connects to the cable core 1 via the insulating ring 11, forming a barrier that blocks unintended current conduction to the outside and resists electrostatic interference from the external environment. Static electricity is common in dry environments; if it enters the cable, it can cause current fluctuations, affecting charging efficiency and damaging electrical equipment. The presence of the insulating protective layer 10 isolates these potential threats, ensuring stable and safe power transmission.
[0039] The pressure-resistant rings 13 are circular in shape, and several sets of pressure-resistant rings 13 are distributed at equal intervals to form a ring-shaped support skeleton, providing support for the internal structure of the cable and maintaining the overall structural stability. The rubber shafts 14 connecting adjacent pressure-resistant rings 13 are made of flexible elastic material. They are distributed at equal intervals in a ring between a pair of pressure-resistant rings 13. When the cable bends, the rubber shafts 14 can adapt to the bending action without hindering the bending action. They can also return to their original position after deformation due to their own elasticity, reducing structural damage caused by frequent deformation.
[0040] The rubber balls 15 between adjacent rubber shafts 14 play a crucial role. These rubber balls 15 are made of flexible, pressure-resistant material, and their surfaces are tightly fitted to the inner walls of the insulation layer 10 and the sheathing layer 12, respectively. When the cable bends, the rubber balls 15 can absorb the stress generated by deformation through their own compression or rolling, preventing damage to localized areas due to excessive stretching or compression. Moreover, the arc-shaped grooves on the inner surface of the sheathing layer 12 are adapted to fit the rubber balls 15, ensuring that the two remain tightly fitted during bending, preventing gaps that could lead to structural loosening and enhancing the stability of the cable during deformation.
[0041] The silicone flexural strip 16 on the inner wall of the first protective section 2 of the cable is of equal length to the first protective section 2 and is distributed in a ring at equal intervals, possessing flexibility and toughness. When the first protective section 2 of the cable bends, the silicone flexural strip 16 can bend synchronously with the outer layer, offsetting part of the tensile stress and preventing loosening of the connection between the first protective section 2 of the cable and the sheathing layer 12. In addition, the first protective section 2 and the second protective section 9 of the cable themselves are made of flexible wear-resistant material. This material has ductility and resilience, and can deform appropriately with external force. Combined with the flexible transition effect of the connecting sheath 6, the entire cable will not have the risk of rigid breakage when bent, improving the cable's adaptability in complex operating environments.
[0042] The abrasion-resistant wrapping layer 4, covering the outer surface of the first protective section 2 of the cable, is in direct contact with the external environment. Made of abrasion-resistant material, it resists friction from objects such as desktops and floors during daily use, reducing surface wear. The upper wrapping layer 5 and lower wrapping layer 7 of the second protective section 9 are symmetrically arranged, both being half-circular rings and made of flexible abrasion-resistant material. This design covers the surface of the second protective section 9, providing protection. Several sets of abrasion-resistant blocks 8 are fixed to the surface of the lower wrapping layer 7 in a matrix distribution. These blocks are made of materials with higher hardness and stronger abrasion resistance, improving the anti-friction capability between the cable and the contact surface, reducing frictional loss with the ground or desktop when the cable is placed. The upper wrapping layer 5 provides protection against friction that the top of the cable may encounter, such as the squeezing friction when stacked with other objects.
[0043] The connection between the cable charging head 3 and the first protective section 2 of the cable is a high-frequency wear area. During the insertion and removal of the charging head, this part is frequently subjected to bending and friction. Therefore, a protective sleeve 17 is fitted over this part. The inner wall of the protective sleeve 17 fits tightly against the outer surface of both the first protective section 2 and the outer surface of the cable charging head 3, enhancing the wear resistance and bending resistance of this part, preventing wear at the interface due to frequent insertion and removal, and extending the overall service life of the cable. The sheathing layer 12 is made of flexible wear-resistant material and is fixed to the insulating protective layer 10 by several sets of pressure-resistant rings 13. It can buffer the friction caused by the deformation of the outer layer, protecting the internal pressure-resistant rings 13, rubber shafts 14, and other components, preventing these critical components from being exposed and damaged due to wear of the outer layer.
[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
