Description
Technical Field
[0001] This utility model relates to the technical field of supporting components for new energy charging equipment, and in particular to a power cord for a new energy photovoltaic-storage-charging integrated charging equipment. Background Technology
[0002] With the rapid development of the new energy vehicle industry, the construction and improvement of charging infrastructure has become a key link supporting the industry's progress. New energy integrated photovoltaic-storage-charging equipment, which integrates photovoltaic power generation, energy storage systems, and charging functions, achieves efficient energy utilization and flexible scheduling, and has been widely used in various scenarios such as residential communities, commercial parking lots, and public charging stations. This type of equipment typically consists of photovoltaic modules, energy storage battery packs, chargers, control systems, and power supply connection components. Among these, the power line, as the core transmission component connecting the charger and the new energy vehicle, plays a crucial role in stably delivering electrical energy to the vehicle's battery; its performance and stability directly affect charging efficiency and operational safety.
[0003] In practical applications, power cords often need to be of a certain length to accommodate the charging needs of vehicles in different parking locations, allowing for flexible dragging. However, existing power cords for integrated photovoltaic, energy storage, and charging equipment generally suffer from insufficient durability. On the one hand, since charging scenarios are mostly outdoors or semi-outdoor environments, power cords need to be in contact with the ground for extended periods and are frequently dragged. The rough texture of the ground causes continuous friction on the outer sheath of the power cord, leading to gradual wear and thinning of the sheath. This not only reduces the insulation performance of the power cord but also easily causes safety hazards such as exposed internal wires and short circuits. On the other hand, the ground at charging sites may often contain sharp objects such as gravel, metal shavings, and glass fragments. The outer sheath of existing power cords is mostly made of ordinary rubber or polyvinyl chloride, which has weak scratch resistance. During dragging, it is easily scratched by sharp objects, causing damage to the internal structure of the power cord, shortening its service life, and increasing equipment maintenance costs and downtime for repairs. This seriously affects the normal operation of the charging equipment and the user experience.
[0004] Therefore, in response to the problem that the power cords of existing integrated photovoltaic, energy storage and charging equipment are easily damaged by wear and scratches during dragging and use, there is an urgent need to design a new type of power cord to improve its durability and safety. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a power cord for a new energy photovoltaic-storage-charging integrated charging device that can prevent wear and tear on the outer sheath during long-term use, avoid scratching the outer sheath by sharp objects, and improve its durability and safety of use.
[0006] This utility model discloses a power cord for an integrated photovoltaic, energy storage, and charging device for new energy, comprising a power cord body, one end of which is electrically connected to the output end of the integrated photovoltaic, energy storage, and charging device, and the other end of which is electrically connected to a charging gun, and further comprising:
[0007] The protective rings are configured in multiple ways, and the multiple protective rings are evenly distributed and fitted on the part of the power cord body that is dragged on the ground;
[0008] The protective ring is provided with a plurality of universal balls evenly distributed on its circumferential sidewalls. The distance between two adjacent universal balls is such that the two lowest adjacent universal balls support the protective ring and prevent it from contacting the ground.
[0009] The protective ring is equipped with a scratch-resistant component, and two adjacent protective rings are connected by the scratch-resistant component.
[0010] Furthermore, the protective ring is detachably mounted on the power cord body, and the outer sheath of the protective ring and the power cord body are made of the same material. The protective ring is provided with a disassembly port, and locking rings are provided on the planar annular sidewalls on both sides of the disassembly port. The two locking rings on the same side are symmetrically located on both sides of the disassembly port. Locking bolts are provided on both sides of the protective ring. The locking bolts pass through the two locking rings on the same side in sequence and are locked by locking nuts. At this time, the protective ring is fixedly mounted on the power cord body.
[0011] Furthermore, the anti-scratch component includes multiple anti-scratch rods, which are evenly distributed and installed on one side of the annular sidewall of the protective ring. The other side of the annular sidewall of the protective ring is provided with multiple insertion slots. The layout of the multiple insertion slots is adapted to the position of the multiple anti-scratch rods. After the multiple protective rings are installed on the power cord body, the multiple anti-scratch rods of the protective rings are slidably inserted into the multiple insertion slots of the adjacent protective rings. The sliding end of the anti-scratch rod is located in the middle of the insertion slot. The anti-scratch rods and the outer sheath of the power cord body are made of the same material.
[0012] Furthermore, the anti-scratch rod is a hollow rod with soft steel strands fixed inside.
[0013] Furthermore, the power cord body has multiple grooves evenly distributed on the circumferential sidewall of the part that is dragged on the ground, and the protective ring has multiple hemispherical protrusions evenly distributed on the inner circumferential sidewall. The multiple hemispherical protrusions of the protective ring are fitted and snapped into the corresponding grooves.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. Significant anti-wear protection: By installing a protective ring with a ball joint at the drag point of the power cord, the ball joint supports the protective ring and the power cord body, preventing the outer sheath of the power cord from directly contacting the ground. This completely avoids continuous friction and wear caused by the rough texture of the ground, effectively maintaining the insulation performance and structural integrity of the outer sheath.
[0016] 2. Significantly enhanced scratch resistance: The protective ring itself can prevent sharp objects such as gravel and metal shavings from directly contacting the power cord. Together with the scratch-resistant components between adjacent protective rings, it forms a continuous protective barrier, preventing the outer sheath from being scratched, reducing the risk of damage to the internal wires, and extending the service life of the power cord.
[0017] 3. Excellent adaptability and flexibility: The sliding fit between the anti-scratch rod and the insertion slot in the anti-scratch component, as well as the rolling characteristics of the universal ball, do not affect the bending and movement of the power cord during dragging, and can adapt to the parking position requirements of different vehicles, ensuring the flexibility of charging operation.
[0018] 4. Convenient and efficient installation and maintenance: The protective ring adopts a detachable structure, which can be quickly installed and replaced through the disassembly port, locking ring and locking bolt and nut; and the protective ring is made of the same material as the outer sheath of the power cord, so only a single damaged protective ring needs to be replaced, reducing maintenance costs and downtime.
[0019] 5. Strong structural stability: The groove of the power cord body and the hemispherical protrusion of the protective ring are fitted together to further fix the position of the protective ring and prevent it from sliding or shifting during dragging, ensuring the continuous effectiveness of the protective structure.

[0027] like Figures 1 to 5 As shown,
[0028] This utility model discloses a power cord for an integrated photovoltaic, energy storage, and charging device for new energy, comprising a power cord body 1, one end of which is electrically connected to the output end of the integrated photovoltaic, energy storage, and charging device, and the other end of which is electrically connected to a charging gun 2, and further comprising:
[0029] The protective ring 3 is provided in multiple ways, and the multiple protective rings 3 are evenly distributed and fitted on the part of the power cord body 1 that is dragged on the ground;
[0030] The protective ring 3 is provided with a plurality of universal balls 4 evenly distributed on its circumferential sidewall. The distance between two adjacent universal balls 4 is such that the two lowest adjacent universal balls 4 lift the protective ring 3 so that it does not contact the ground.
[0031] The protective ring 3 is provided with a scratch-resistant component, and two adjacent protective rings 3 are connected by the scratch-resistant component.
[0032] In this embodiment,
[0033] Protective ring 3: Fitted onto the dragging part, serving as the core protective carrier, supporting the omnidirectional ball 4 and the anti-scratch component;
[0034] Omnidirectional ball 4: Evenly distributed on the side wall of the protective ring 3, it lifts the protective ring 3 to achieve non-contact support between the power cord and the ground, reducing friction;
[0035] Scratch-resistant component: Connects adjacent protective rings 3 to form a continuous protective structure, preventing sharp objects from entering.
[0036] As a preferred embodiment of the above, the protective ring 3 is detachably mounted on the power cord body 1, and the protective ring 3 and the outer sheath of the power cord body 1 are made of the same material. The protective ring 3 is provided with a disassembly port 5. Locking rings 6 are provided on the annular sidewalls of the protective ring 3 on both sides of the disassembly port 5. The two locking rings 6 on the same side are symmetrically located on both sides of the disassembly port 5. Locking bolts 7 are provided on both sides of the protective ring 3. The locking bolts 7 pass through the two locking rings 6 on the same side in sequence and are locked by locking nuts 8. At this time, the protective ring 3 is fixedly mounted on the power cord body 1.
[0037] In this embodiment,
[0038] Disassembly port 5: Provides opening and closing space for the protective ring 3, making it easy to install on the existing power cord without disassembling the charging gun 2;
[0039] Locking rings 6: symmetrically distributed on both sides of the disassembly port 5, providing a support point for the locking bolts 7 to pass through;
[0040] Locking bolt 7 and locking nut 8: Pass through the locking ring 6 and tighten to fix the protective ring 3 to the power cord body 1, ensuring a secure installation.
[0041] As a preferred embodiment of the above embodiment, the anti-scratch component includes a plurality of anti-scratch rods 9, which are evenly distributed and installed on one side of the annular sidewall of the protective ring 3. The other side of the annular sidewall of the protective ring 3 is provided with a plurality of insertion slots 10. The layout of the plurality of insertion slots 10 is adapted to the position of the plurality of anti-scratch rods 9. After the plurality of protective rings 3 are installed on the power cord body 1, the plurality of anti-scratch rods 9 of the protective ring 3 are slidably inserted into the plurality of insertion slots 10 of the adjacent protective ring 3. The sliding end of the anti-scratch rod 9 is located in the middle part of the insertion slot 10. The anti-scratch rod 9 and the outer sheath of the power cord body 1 are made of the same material.
[0042] In this embodiment,
[0043] Anti-scratch bar 9: evenly distributed on one side of the protective ring 3, inserted into the insertion slot 10 of the adjacent protective ring 3 to form lateral protection and block sharp objects;
[0044] Insertion slot 10: Located on the other side of the protective ring 3, it provides sliding space for the anti-scratch rod 9, allowing the power cord to bend, and at the same time, it works with the anti-scratch rod 9 to form continuous protection.
[0045] As a preferred embodiment of the above embodiment, the anti-scratch rod 9 is configured as a hollow rod, and a soft steel strand 11 is fixedly installed inside it;
[0046] In this embodiment,
[0047] Soft steel strand 11: Built into the hollow anti-scratch rod 9, it enhances the bending and impact resistance of the anti-scratch rod 9 without affecting the flexibility of the rod body, effectively preventing the anti-scratch rod 9 from being cut and improving the reliability of protection.
[0048] As a preferred embodiment of the above, the power cord body 1 has a plurality of grooves 13 evenly distributed on the circumferential sidewall of the part that is dragged on the ground, and the protective ring 3 has a plurality of hemispherical protrusions 12 evenly distributed on the inner circumferential sidewall, and the plurality of hemispherical protrusions 12 of the protective ring 3 are fitted and snapped into the plurality of grooves 13 of the corresponding parts.
[0049] In this embodiment,
[0050] Groove 13: Formed on the side wall of the power cord drag section, providing a locking point for the hemispherical protrusion 12;
[0051] Hemispherical protrusion 12: Located on the inner circumferential side wall of the protective ring 3, it is engaged with the groove 13 to restrict the axial sliding of the protective ring 3 and ensure the stability of the protective position.
[0052] The working principle of this utility model is as follows:
[0053] At the ground dragging section of the power cord body 1, multiple protective rings 3 are fitted onto it through the disassembly port 5. Locking bolts 7 are passed through locking rings 6 and screwed into locking nuts 8 to secure the protective rings 3, ensuring that the hemispherical protrusions 12 of the protective rings 3 are engaged in the grooves 13 of the power cord to prevent slippage. Adjacent protective rings 3 are connected by anti-scratch rods 9 inserted into insertion slots 10, forming a continuous protective structure covering the dragging area. When the power cord is dragged, the universal balls 4 on the protective rings 3 contact the ground and roll, lifting the protective rings 3 and the power cord body 1, preventing the outer sheath of the power cord from rubbing against the ground. The protective rings 3 themselves and the anti-scratch components can block sharp objects such as gravel and metal fragments. The soft steel strands 11 built into the anti-scratch rods 9 enhance impact resistance. Simultaneously, the sliding engagement of the anti-scratch rods 9 and the insertion slots 10, combined with the rolling of the universal balls 4, does not affect the bending and movement of the power cord, ultimately achieving dual protection against wear and scratches, improving durability and safety.
[0054] The outer sheath of the power cord body 1 is typically made of chlorinated polyvinyl chloride (CPVC), cross-linked polyethylene (XLPE), or thermoplastic elastomer (TPE / TPU).
[0055] The uses and effects of the protective ring 3 being made of the same material as the outer sheath are as follows:
[0056] Application: To match the physical properties of power cords, such as flexibility and coefficient of thermal expansion, to maintain insulation and prevent secondary damage to the power cords.
[0057] Effects: Synchronous deformation under high and low temperatures, preventing loosening and displacement; filling insulation to avoid electric field distortion; reducing wear and deformation caused by friction and hardness mismatch.
[0058] The purpose and effects of using the same material as the scratch-resistant bar 9 and the outer sheath are as follows:
[0059] Applications: To adapt to the deformation requirements of protective systems, forming a continuous scratch-resistant system, and improving the durability and compatibility of components.
[0060] Effects: It does not break when the power cord bends, making dragging smoother; it has consistent scratch resistance with no weak points in protection; and it ages at the same rate, reducing maintenance costs and adaptation difficulties.
[0061] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
