Description

Technical Field

[0001] The present invention relates to the technical field of automobile cables, and in particular to a comprehensive cable for new energy vehicles. Background Art

[0002] The rapid development of the new energy vehicle industry has put forward higher requirements for the reliability of its electrical system. Among them, cables are core transmission components, and their performance directly affects the safety and stability of the vehicle. Cables for new energy vehicles are mainly used for power transmission, signal transmission and control systems, and are usually composed of conductors, insulation layers, shielding layers and outer sheaths. These cables not only need to ensure stable power and signal transmission when working, but also have characteristics such as high temperature resistance, wear resistance and bending resistance to cope with the complex in-vehicle wiring environment.

[0003] In the actual application of new energy vehicles, the cable needs to be bent and fixed many times when it is routed, especially in the routing layout in a small space, the cable bending and fixing process is more frequent. However, due to the certain elasticity of the cable, after bending, a certain contact stress is often generated between the cable fixing and the cable sheath. Over time, this stress will cause the extrusion between the cable outer sheath and the fixing to intensify, which will cause the outer sheath to wear and the fixing to loosen. The wear of the outer sheath may increase the risk of cable failure, and the loosening of the fixing may cause the joint to break or poor contact, which will affect the normal operation of the vehicle electrical system. Summary of the invention

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0030] like Figures 1 to 7 As shown, an embodiment of the present invention provides an integrated cable for new energy vehicles, which includes a conductor 110, an inner shielding layer 120, an insulating layer 130, an outer shielding layer 140, an outer sheath 150 and a cooling tube 210.

[0031] The conductor 110 is made of 99.99% oxygen-free copper, ensuring that the conductor 110 has good electrical conductivity.

[0032] The inner shielding layer 120 is coated on the outside of the conductor 110 . Specifically, the inner shielding layer 120 is tightly connected to the conductor 110 . The inner shielding layer 120 is made of a semi-conductive material with very low resistivity and thin thickness. The inner shielding layer 120 is used to make the electric field on the outer surface of the conductor 110 uniform.

[0033] The insulating layer 130 is coated on the outside of the inner shielding layer 120. The insulating layer 130 is made of cross-linked polyethylene and is tightly connected to the inner shielding layer 120. The inner shielding layer 120 can prevent partial discharge between the conductor 110 and the insulating layer 130 caused by the rough surface of the conductor 110 and the air gap generated by the twisting of the conductor 110.

[0034] The outer shielding layer 140 is coated on the outside of the insulating layer 130, and the outer shielding layer 140 is closely connected to the insulating layer 130. The outer shielding layer 140 and the inner shielding layer 120 jointly prevent the electric field generated by the conductor 110 from affecting external devices. The outer shielding layer 140, the insulating layer 130, the inner shielding layer 120 and the conductor 110 can form a complete wire, and the wire formed by the outer shielding layer 140, the insulating layer 130, the inner shielding layer 120 and the conductor 110 is cylindrical.

[0035] The outer sheath 150 is cylindrical and has a filling cavity that runs through it from top to bottom. The length of the outer sheath 150 is equal to the length of the wire. Multiple wires can be placed in the filling cavity. The outer sheath 150 is used to surround the multiple wires into a complete cable. The filling cavity is filled with a filler 160, which is used to maintain the cylindrical shape of the cable. Specifically, the filler 160 is jute or a rubber strip. The filler 160 is in a strip shape. The filler 160 can be filled in the gap between two adjacent wires. The filler 160 can be molded into any shape to adapt to cables of different thicknesses.

[0036] There are multiple cooling tubes 210, all of which are arranged in the filling cavity. The multiple cooling tubes 210 are evenly distributed in the circumferential direction of the outer sheath 150. The cooling tubes 210 can directly contact the wires. The filler 160 can be filled in the gap between two adjacent cooling tubes 210. At the same time, the filler 160 can also be filled in the gap between the cooling tube 210 and the wires. The cooling tube 210 has a cooling cavity 211 inside, and the cooling cavity 211 is filled with a coolant. The coolant is used to cool the heat generated by the wires when they are working, ensuring that the wires are at a safe working temperature. The cooling tube 210 is arranged to be wavy along the axis direction of the outer sheath 150. When the wire is bent, the cooling tube 210 can be deformed. Specifically, when the cable needs to be fixed on the car, the outer sheath 150 is fixed on the car using a cable fixing member. When the cable needs to be bent, the cable fixing member is used to fix it in the bending area of ​​the cable. At the same time, in the bending area of ​​the cable, the outer sheath 150 is deformed, and the outer sheath 150 has an inner side close to the center of the bending circle and an outer side away from the center of the bending circle. Since the cooling tube 210 is wavy in the axis direction of the outer sheath 150, the cooling tube 210 can be deformed when the wire is bent, and the cooling tube 210 on the inner side of the outer sheath 150 The cooling tube 210 on the outside of the outer sheath 150 is squeezed and stretched. After the cooling tube 210 is squeezed, the wave degree of the cooling tube 210 is aggravated inside the outer sheath 150 per unit length, resulting in a relatively improved cooling performance of the cooling tube 210 on the wire. After the cooling tube 210 is stretched, the wave degree of the cooling tube 210 on the unit length of the outer sheath 150 is reduced, resulting in a relatively reduced cooling performance of the cooling tube 210 on the wire. At this time, in the bending area of ​​the cable, the temperature inside the outer sheath 150 is slightly lower than the temperature outside the outer sheath 150. Under the effect of thermal expansion and contraction, the stress generated between the cable fixing and the cable when the cable is actively reset after bending is reduced.

[0037] The present invention provides a comprehensive cable for new energy vehicles. When preparing the cable for use in a car, the inner shielding layer 120 is coated on the outside of the conductor 110, the insulating layer 130 is coated on the outside of the inner shielding layer 120, and the outer shielding layer 140 is coated on the outside of the insulating layer 130. The outer shielding layer 140, the insulating layer 130, the inner shielding layer 120 and the conductor 110 can form a complete wire. A plurality of wires are placed in the filling cavity of the outer sheath 150. At the same time, a plurality of cooling tubes 210 are placed in the filling cavity of the outer sheath 150. Then, the gap in the filling cavity is filled with a filler 160 to ensure that the outer shape of the outer sheath 150 is cylindrical. When the prepared cable is assembled on a car for use, the outer sheath 150 is fixed on the car. When the cable is bent, the bending of the cable is fixed to the car. In the region, the outer sheath 150 has a compressed inner side and a stretched outer side. Accordingly, the cooling tube 210 is arranged in a wavy shape along the axial direction of the outer sheath 150. In the bending region of the cable, the cooling tube 210 on the inner side of the outer sheath 150 is squeezed, and the cooling tube 210 on the outer side of the outer sheath 150 is stretched. After the cooling tube 210 is squeezed, the cooling performance of the cooling tube 210 on the wire is relatively improved. After the cooling tube 210 is stretched, the cooling performance of the cooling tube 210 on the wire is relatively reduced. At this time, in the bending region of the cable, the temperature on the inner side of the outer sheath 150 is slightly lower than the temperature on the outer side of the outer sheath 150. Under the effect of thermal expansion and contraction, the stress generated between the cable fixing and the cable when the cable is actively reset after bending is reduced, thereby reducing the probability of failure of the automotive electrical system due to the cable.

[0038] In one embodiment, each cooling tube 210 is provided with a limiter, and the cooling tubes 210 are evenly distributed in the circumferential direction of the outer sheath 150. When the cable is installed on the car, the outer sheath 150 is in direct contact with the cable fixing member. When the cable needs to be bent, the bending area of ​​the outer sheath 150 is bent into an arc, and the outer sheath 150 has an inner side close to the center of the arc and an outer side away from the center of the arc. Since the cooling tubes 210 are wavy in the axial direction of the outer sheath 150, when the outer sheath 150 is bent, multiple cooling tubes 210 will be deformed. Part of the cooling tubes 210 in the inner area of ​​the outer sheath 150 is compressed, and part of the cooling tubes 210 in the outer area of ​​the outer sheath 150 is stretched. Among them, the limit member is used to prevent the cooling tube 210 from resetting after being compressed. After the cooling tube 210 is bent, the cooling tube 210 has a tendency to actively reset. Under the action of the limit member, the limit member prevents the compressed cooling tube 210 from resetting, thereby reducing the force of the inner side of the outer sheath 150 to expand outward, and further reducing the contact stress between the outer sheath 150 and the cable fixing part.

[0039] In one embodiment, the length direction of the cooling tube 210 is parallel to the axis direction of the outer jacket 150, and the cooling tube 210 has a first side wall 212 close to the axis of the outer jacket 150 and a second side wall 213 away from the axis of the outer jacket 150. When the cooling tube 210 is arranged in a wavy shape along the axis direction of the outer jacket 150, the first side wall 212 and the second side wall 213 of the cooling tube 210 are both wavy. The limiting member is arranged at intervals on the first side wall 212 and / or the second side wall 213. Specifically, the limiting member is arranged at intervals on the first side wall 212, or the limiting member is arranged at intervals on the second side wall 213, or the limiting member is arranged on both the first side wall 212 and the second side wall 213. Further, no matter whether the limiting member is arranged on the first side wall 212 or the second side wall 213, the limiting member can always prevent the cooling tube 210 from resetting when the cooling tube 210 is compressed.

[0040] In one embodiment, the stopper includes a plurality of first bite plates 220 and a plurality of second bite plates 230. The first side wall 212 and the second side wall 213 of the cooling tube 210 are both wavy, and there are trough regions in the first side wall 212 and the second side wall 213 of the cooling tube 210. Specifically, in the first side wall 212 of the cooling tube 210, the trough region is open toward the direction of the axis of the outer sheath 150, and in the second side wall 213 of the cooling tube 210, the trough region is open toward the direction away from the axis of the outer sheath 150. In this embodiment, taking the stopper being disposed on the first side wall 212 of the cooling tube 210 as an example, the trough region in the first side wall 212 has an upper trough side wall and a lower trough side wall, wherein, when the cooling tube 210 is not bent, the upper trough side wall and the lower trough side wall are slightly V-shaped openings. A plurality of first bite plates 220 are arranged on the upper side wall of the trough, and a plurality of second bite plates 230 are arranged on the lower side wall of the trough. In the same trough area, the first bite plates 220 and the second bite plates 230 are staggeredly arranged. By limiting the positions of the first bite plates 220 and the second bite plates 230, it is ensured that the first bite plate 220 can enter between two adjacent second bite plates 230, and the second bite plate 230 can enter between two adjacent first bite plates 220, and there is resistance when the first bite plates 220 and the second bite plates 230 move relative to each other. Furthermore, when the outer sheath 150 is bent, the cooling tube 210 on the inner side of the outer sheath 150 is squeezed and deformed, and the first bite plate 220 and the second bite plate 230 on the squeezed cooling tube 210 engage with each other. When the outer sheath 150 is ready to be reset, the reset force of the outer sheath 150 needs to overcome the resistance of the relative movement of the first bite plate 220 and the second bite plate 230, thereby consuming the force of the inner side of the outer sheath 150 to expand outward, thereby reducing the contact stress between the outer sheath 150 and the cable fixing.

[0041] In one embodiment, the first bite plate 220 and the second bite plate 230 are both provided with friction protrusions 240, and the friction protrusions 240 can be deformed. When the cable is bent manually or with the help of external electrical equipment, it is sufficient to overcome the resistance of the first bite plate 220 and the second bite plate 230 when the cable is bent. Furthermore, by setting the friction protrusions 240 to be a deformable material, it is possible to prevent the friction protrusions 240 from being damaged when the cable is bent. For example, the friction protrusions 240 are made of rubber.

[0042] In one embodiment, the first bite plate 220 and the second bite plate 230 are both hollow inside, and the hollow chambers inside the first bite plate 220 and the second bite plate 230 are both connected to the cooling chamber 211. By setting the first bite plate 220 and the second bite plate 230 as hollow materials, when there is cooling liquid inside the first bite plate 220 and the second bite plate 230, the cooling effect of the cooling tube 210 on the wire can be improved.

[0043] In one embodiment, each cooling tube 210 is provided corresponding to a wire. Specifically, the number of cooling tubes 210 is the same as the number of wires. The wires are evenly distributed around the axis of the outer sheath 150, and any two adjacent wires abut against each other. Figure 1 As shown, the cooling tube 210 and the wires are set in number, the three wires are abutted against each other, the cooling tube 210 is set between two adjacent wires, the cooling tube 210 can directly contact the outer shielding layer 140 of the two wires, and the cooling tube 210 can contact the wires to the greatest extent, thereby fully cooling the wires.

[0044] In one embodiment, the outer sheath 150 includes a steel belt and a protective layer, the protective layer is made of polyvinyl chloride, and the steel belt can be embedded inside the protective layer, and the steel belt can improve the compression resistance of the protective layer. Furthermore, by arranging the steel belt inside the protective layer, insects and ants can be prevented from biting the cable.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
