Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a bend-resistant cable for new energy vehicles. Background Technique

[0002] A cable is a device for transmitting electrical energy or signals, usually composed of several or several groups of wires. Each group of wires is insulated from each other and often twisted around a central wire. The whole is covered with a highly insulating covering layer. In new energy projects, cables are required to connect between various components. In the prior art, traditional new energy vehicles need to use cables during the rotation of components or the charging process. However, these cables need to be bent frequently during use to adjust the angle.

[0003] The existing bend-resistant cables for new energy vehicles generally adopt the production methods of a tensile layer and spiral stranding. When the cable is too tightly stranded during the stranding process, the space inside the cable will be greatly compressed, which will seriously limit its deformation ability. As a result, when being squeezed or bent, it may be forced to undergo uneven or excessive deformation due to the lack of buffer space. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a bend-resistant cable for new energy vehicles to solve the technical problem that when being squeezed or bent, it may be forced to undergo uneven or excessive deformation due to the lack of buffer space.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A bend-resistant cable for new energy vehicles includes a steel wire rope. High-voltage line segments are wound around both sides of the steel wire rope. Low-voltage line segments are arranged on the upper and lower sides of the steel wire rope. There are two groups of low-voltage line segments, and the two groups of low-voltage line segments are distributed in a mirror image. A control line segment is arranged on one side of the low-voltage line segment. A non-woven fabric layer is arranged on the outside of the control line segment. A filler is filled between the non-woven fabric layer and the steel wire rope. A silicone rubber insulation layer is arranged on the outside of the non-woven fabric layer. A metal shielding net is sleeved on the outside of the silicone rubber insulation layer. A protective sleeve is sleeved on the outside of the metal shielding net.

[0006] By adopting the above technical solution, the steel wire rope serves as the core support structure of the cable, providing basic mechanical strength and stability. The high-voltage segments are used to transmit high-voltage electricity, and their presence ensures that the cable can carry high voltages. The low-voltage segments are used to transmit electricity at a lower voltage, and the control segments are used to transmit control signals, ensuring the accuracy and responsiveness of the vehicle charging operation. The non-woven fabric layer provides additional protection and cushioning. The filling material is made of silica gel particles, and the silicone rubber insulation layer prevents current leakage and short circuits, ensuring the safe operation of the cable. The silicone rubber material can also provide heat resistance and chemical corrosion resistance characteristics. The metal shielding net can reduce electromagnetic interference. The metal shielding net is double-woven by tinned soft round copper wires through a wire braiding machine, ensuring the signal quality transmitted in the cable. The protective sleeves are all made of fluoroplastic materials, providing high wear resistance and strength.

[0007] Further, a ball head is fixed at one end of the protective sleeve, and a ball groove is fixedly connected to the other end of the protective sleeve, and the ball head and the ball groove are adapted to each other.

[0008] By adopting the above technical solution, the structural design of the ball head and the ball groove allows the cable to have more movement space at the connection, which makes the cable more flexible when bending or adjusting the direction is required, and this design extends the service life of the cable.

[0009] Further, extension lines are fixedly connected to one ends of the high-voltage segment, the low-voltage segment and the control segment, and another group of high-voltage segment, low-voltage segment and control segment are fixedly connected to one end of the extension line.

[0010] By adopting the above technical solution, by using extension lines to connect different segments of the cable, on the one hand, the modular design of the cable can be realized, making the cable easier to assemble, adjust and maintain, and easier to replace or repair the problematic parts without having to replace the entire cable.

[0011] Further, the metal shielding net is woven in a high-density manner.

[0012] By adopting the above technical solution, the high-density woven metal shielding net can more effectively reduce electromagnetic interference, protect the signal transmission inside the cable from external electromagnetic waves, and improve the stability and accuracy of the signal.

[0013] Further, the space between one side of the ball groove and the protective sleeve is sealed by a rubber material.

[0014] By adopting the above technical solution, the rubber material forms a sealing layer between the ball groove and the protective sleeve, preventing moisture, dust and other pollutants from entering the cable interior and protecting the cable from the effects of moisture and corrosion.

[0015] Further, there are two high-voltage segments, and the two high-voltage segments are arranged in a mirror image.

[0016] By adopting the above technical solution, two high-voltage line segments can provide sufficient power supply to achieve the maximum charging speed.

[0017] Furthermore, a rubber pipeline is provided between the two high-voltage line segments.

[0018] By adopting the above technical solution, the rubber pipeline, as the core of the cable, can, on the one hand, improve the overall structural strength, and at the same time provide physical isolation for the two high-voltage line segments, reducing the direct contact and friction between them, thereby protecting the line segments from damage.

[0019] Furthermore, the inside of the rubber pipeline is filled with insulating oil.

[0020] By adopting the above technical solution, the insulating oil is filled inside the rubber pipeline to provide additional electrical insulation, helping to prevent current leakage and short-circuit phenomena. The insulating oil remains stable at high temperatures and helps to disperse the heat generated by current transmission.

[0021] In summary, the main beneficial effects of the present utility model are as follows:

[0022] 1. By providing a ball head, a ball groove and an extension wire, the present utility model utilizes a part of the extension wire that extends outwards, so that when the cable is bent, an additional deformation amount can be provided to prevent the cable from breaking due to being too tight. At the same time, the ball head and the ball groove can strengthen the connection strength at the extension wire, ensuring that the protective sleeves at the ball groove and the ball head will not deform due to the distance of the extension wire.

[0023] 2. By providing a metal shielding net, the present utility model utilizes the high-density metal shielding net, and the high-density metal shielding net can improve the tensile strength of the entire cable and prevent the shielding net from flanging due to excessive bending of the cable.

[0024] 3. By providing a rubber pipeline and insulating oil, the present utility model utilizes the rubber pipeline as the framework of the cable. When local bending occurs, the insulating oil can flow from the bent part to both sides, creating space at the bent part to avoid excessive extrusion of the cable. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0031] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0032] Embodiment 1:

[0033] A bend-resistant cable for new energy vehicles, as Figures 1-4 shown, includes a steel wire rope 1. High-voltage line segments 2 are wound around both sides of the steel wire rope 1. Low-voltage line segments 3 are arranged on the upper and lower sides of the steel wire rope 1. There are two groups of low-voltage line segments 3, and the two groups of low-voltage line segments 3 are mirror-symmetrically distributed. A control line segment 4 is arranged on one side of the low-voltage line segment 3. A non-woven fabric layer 5 is arranged outside the control line segment 4. A filler 6 is filled between the non-woven fabric layer 5 and the steel wire rope 1. A silicone rubber insulation layer 7 is arranged outside the non-woven fabric layer 5. A metal shielding net 8 is sleeved outside the silicone rubber insulation layer 7. A protective sleeve 9 is sleeved outside the metal shielding net 8. The steel wire rope 1 serves as the core support structure of the cable, providing basic mechanical strength and stability. Using the steel wire rope 1 can ensure that the cable maintains its shape and structural integrity during long-term use. The high-voltage line segments 2 are used to transmit high-voltage electricity, and their presence ensures that the cable can carry high voltages and is suitable for parts with high energy requirements in new energy vehicles. The low-voltage line segments 3 are used to transmit electricity at a lower voltage. The control line segment 4 is used to transmit control signals, ensuring the accuracy and responsiveness of the vehicle charging operation. The non-woven fabric layer 5 provides additional protection and buffering, reducing friction and wear between internal lines and extending the service life of the cable. The filler 6 is made of silicone particles. The silicone rubber insulation layer 7 prevents current leakage and short circuits, ensuring the safe operation of the cable. The silicone rubber material can also provide heat resistance and chemical corrosion resistance characteristics. The metal shielding net 8 is made of tinned soft round copper wire double-woven by a wire braiding machine, reducing electromagnetic interference and ensuring the signal quality transmitted in the cable. The protective sleeve 9 protects the cable from external environmental factors such as water, grease, and physical damage, and is made of fluoroplastic material, providing high wear resistance and strength, thus ensuring its long-term stable operation.

[0034] Refer to Figure 1 、 Figure 2and Figure 3 One end of the protective sleeve 9 is fixed with a ball head 10, and the other end of the protective sleeve 9 is fixedly connected with a ball groove 11. The ball head 10 and the ball groove 11 are adapted to each other. The structural design of the ball head 10 and the ball groove 11 allows more movement space for the cable at the connection. This design makes the cable more flexible when it needs to be bent or adjusted in direction. When the cable is bent or twisted, the design of the ball head 10 and the ball groove 11 can effectively disperse and absorb the stress caused by physical deformation, allowing bending to be achieved through the relative rotation of the ball head 10 and the ball groove 11, thereby providing a larger bending rate without damaging the internal circuit. This design extends the service life of the cable.

[0035] Refer to Figure 1 、 Figure 2 and Figure 3 One end of the high-voltage line segment 2, the low-voltage line segment 3 and the control line segment 4 is fixedly connected with an extension line 12. One end of the extension line 12 is fixedly connected with another group of high-voltage line segment 2, low-voltage line segment 3 and control line segment 4. By using the extension line 12 to connect between different sections of the cable, on the one hand, the modular design of the cable can be realized, making the cable easier to assemble, adjust and maintain. And the length of the extension line 12 itself can provide additional deformation, providing enough rotation space for the ball head 10 and the ball groove 11. At the same time, if a certain part of the cable fails, the design of the extension line 12 allows the problematic part to be replaced or repaired more easily without having to replace the entire cable.

[0036] Refer to Figure 1 、 Figure 2 and Figure 3 The metal shielding net 8 is woven in a high-density manner. The metal shielding net 8 woven in a high density can more effectively reduce electromagnetic interference, protect the signal transmission inside the cable from being interfered by external electromagnetic waves. Due to the high weaving density, the metal shielding net 8 is physically stronger and more durable, and can better resist the influence of external forces such as stretching and extrusion. The metal shielding net 8 woven in a high density can effectively reduce interference during data transmission, improve the stability and accuracy of the signal, and also extend the service life of the cable due to its enhanced physical strength, reducing the maintenance and replacement costs caused by damage or wear.

[0037] Refer to Figure 1 、 Figure 2 and Figure 3 One side of the ball groove 11 and the protective sleeve 9 are sealed by a rubber material. The rubber material forms a sealing layer between the ball groove 11 and the protective sleeve 9, preventing moisture, dust and other pollutants from entering the cable interior, protecting the cable from the influence of moisture and corrosion, reducing the wear and corrosion of internal components, thereby extending the service life of the cable, and further reducing potential electrical failures caused by changes in the external environment, ensuring the stable performance of the cable under various operating conditions.

[0038] Refer to Figure 1 , Figure 2 and Figure 3 , two high-voltage line segments 2 are provided. The two high-voltage line segments 2 are arranged in a mirror image. The two high-voltage line segments 2 can provide sufficient power supply to achieve the maximum charging speed. At the same time, the high-voltage line segments 2 with a mirror layout can cancel out the electromagnetic interference generated by each other, improving the overall performance.

[0039] The implementation principle of the present utility model is as follows: First, the ball heads 10 and ball grooves 11 of each section are clamped with each other, and the rubber sealing end faces are used to prevent water leakage. When the cable is stressed, one section of the protective sleeve 9 relies on the metal shielding net 8 to obtain a smaller deformation amount, while the ball heads 10 and ball grooves 11 generate a larger deformation amount, which can straighten the extension line 12, ensuring that the high-voltage line segment 2, the low-voltage line segment 3, and the control line segment 4 will not be deformed due to the pulling force.

[0040] Embodiment 2:

[0041] Refer to Figure 4 , a rubber pipeline 13 is provided between the two high-voltage line segments 2. The rubber pipeline 13 is the core of the cable. On the one hand, it can improve the overall structural strength, and at the same time provide physical isolation for the two high-voltage line segments 2, reducing the direct contact and friction between them, thereby protecting the line segments from damage. The rubber material has good elasticity and buffering characteristics, which can absorb and relieve the stress caused by external impacts. By reducing the direct friction and interaction between the high-voltage line segments 2, it helps to extend the service life of the cable, and at the same time provides space for the filling of the internal insulating oil 14.

[0042] Refer to Figure 4 , the inside of the rubber pipeline 13 is filled with insulating oil 14. The insulating oil 14 is filled inside the rubber pipeline 13 to provide additional electrical insulation, helping to prevent current leakage and short-circuit phenomena. The insulating oil 14 remains stable at high temperatures, helping to disperse the heat generated by current transmission, protecting the cable from overheating damage. At the same time, using the fluidity of the insulating oil 14, when a certain point is pressed, the insulating oil 14 flows, giving way to space, providing sufficient space for bending, and avoiding damage to the cable due to pressure.

[0043] The implementation principle of the present utility model is as follows: First, when local bending occurs, the insulating oil 14 can flow from the bending part to both sides, making space at the bending part, and the high-voltage line segment 2, the low-voltage line segment 3, and the control line segment 4 obtain space for deformation, preventing the high-voltage line segment 2, the low-voltage line segment 3, and the control line segment 4 from being bent and damaged due to excessive pressure.

[0044] Parts not involved in the present utility model are the same as or can be implemented using the prior art, and will not be elaborated here.

[0045] Although embodiments of the present utility model have been shown and described, the specific embodiments are only interpretations of the present utility model and do not limit the utility model. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations that do not contribute creatively to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
