Description

Technical Field

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

[0002] New energy vehicles (NEVs) are vehicles powered by non-fossil fuels, primarily including battery electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs), and fuel cell vehicles (FCVs). New energy vehicle cables are used to connect EVs to charging stations or devices. They transmit electrical energy, either charging the power source or transferring it to the EV's battery.

[0003] Among them, after search, it was found that the patent application number CN202321755673.9 discloses a break-resistant cable for new energy vehicles, including a cable body, a protective layer fixedly sleeved inside the cable body, a connecting layer arranged inside the protective layer, and a connection between the protective layer and the connecting layer is fixedly connected with reinforcing ribs arranged in a ring shape, an outer tube fixedly sleeved inside the connecting layer, and an inner tube arranged inside the outer tube.

[0004] When this structure is in use, the insulating filling layer protects the outer single-core conductor and the inner single-core conductor, and then the wear-resistant diaphragm and the shielding layer cooperate to isolate the erosion of rainwater. Then, the polyester fiber non-woven fabric layer further strengthens the bending strength of the cable body, thereby reducing the occurrence of breakage after use, thereby improving the use effect. However, the structure itself has low impact resistance and anti-breakage performance when in use, and it is not easy to reduce the impact force on the cable, causing the cable to be easily damaged. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a break-resistant cable for new energy vehicles, aiming to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned object, the present invention provides the following technical solutions: a cable for new energy vehicles that is resistant to breakage, comprising an outer cable body for protection, wherein a compression protection component is provided within the outer cable body;

[0007] The compression protection component includes a supporting soft strip arranged in the outer cable body, and a plurality of first blocks for support are arranged on the outside of the supporting soft strip, and a second block for support is arranged on one side of multiple first blocks, and two deformable supporting ribs are arranged on multiple first blocks and second blocks, and each of the first blocks and second blocks is slidably connected to the supporting ribs, and a dislocation cavity for dislocation is formed between multiple adjacent first blocks and second blocks, and a limiting arc groove matching the supporting soft strip is provided on the side of the first block and the second block facing the supporting soft strip, and the vertical cross-sectional shape of the limiting arc groove is set to an arc shape, and the vertical cross-sectional shape of the first block and the second block is set to a trapezoidal shape, and the trapezoidal cross-sections of each of the first block and the second block are relatively arranged.

[0008] It can be seen that in the above technical solution, the force-bearing point is deformed and the impact force is transmitted to the first block and the second block. When the first block and the second block are deformed by the impact force, they can squeeze the adjacent dislocation cavities against each other, so that the first block and the second block can be displaced with each other when subjected to force, and the impact force on the cable is transmitted to avoid damage to the cable due to a large load at a certain point. When the first block and the second block are displaced, they can squeeze each other to reduce the pressure on each first block and the second block, so that it will not be concentrated on a certain point, thereby reducing the bearing capacity of a single structure, which can effectively improve the deformation resistance of the cable and avoid the cable from breaking due to excessive pressure.

[0009] A plurality of deformable first rubber columns are arranged inside the support soft strip, and a deformable second rubber column is arranged on each of the first rubber columns. An inner lining is arranged inside the support soft strip and on the outside of the second rubber column and the first rubber column. The interior of the inner lining is filled with a non-Newtonian fluid filler. A reinforcement sleeve for protection is provided on the surface of the support soft strip. The reinforcement sleeve includes a plurality of high-strength and high-modulus polyethylene fiber filaments, and the high-strength and high-modulus polyethylene fiber filaments are staggered.

[0010] It can be seen that in the above technical solution, the filled first rubber column and the second rubber column and the non-Newtonian fluid filler make the fluid in the non-Newtonian fluid filler become more viscous and compact, thereby improving the impact resistance of the device. Moreover, after the reinforcement sleeve is set, the deformation resistance of the supporting soft strip can be effectively improved, thereby preventing the cable from being damaged by excessive impact force.

[0011] An adaptive support body for protecting the wire is provided on the side of the support strip away from the first block and the second block, and the adaptive support body includes a plurality of first connecting members and a second connecting member arranged side by side, and the outer sides of the first connecting member and the second connecting member are provided with heat dissipation holes, the first connecting member and the second connecting member are arranged end to end, and the top and bottom of the first connecting member and the second connecting member are provided with reinforcement members for protection, and the first connecting member and the second connecting member are respectively detachably connected to the corresponding reinforcement members, and one end of the first connecting member and the second connecting member and both sides of the surface of the first connecting member and the second connecting member are provided with a first annular groove for limiting, and the other end of the first connecting member and the second connecting member and both sides of the inner wall of the first connecting member and the second connecting member are provided with a second annular groove, and both ends of the first connecting member and the second connecting member are provided with a transition arc slope, the vertical cross-section shape of the first annular groove and the second annular groove are both set to be arc-shaped, the first annular groove and the second annular groove match, the inner wall of the second annular groove is penetrated by a center hole for limiting, and the inner wall of the second annular groove is provided with a connecting column matching the center hole.

[0012] It can be seen that in the above technical solution, the first connector and the second connector can be installed together in an end-to-end manner through the second annular groove and the first annular groove, and can also be rotated through the center hole and the axis point of the connecting column, which makes it easy for the first connector and the second connector to perform adaptive angle adjustment when the cable is bent. The second annular groove and the first annular groove not only ensure that the first connector and the second connector are butt-jointed and installed together, but also can limit the adjacent first connector and second connector when adjusting the angle, avoiding the tension generated by the deformation of the cable bending part causing the protective performance of the bending part to become lower, so as to improve the anti-bending performance of the cable. The copper core of the cable is supported by the first connector and the second connector, and the outer cable body, the supporting soft strip, the first connector and the second connector protect the copper core of the cable. At the same time, the heat generated by the copper core of the cable during operation can be discharged through the heat dissipation holes.

[0013] The present invention has the following advantages:

[0014] 1. The copper core of the cable of the present invention can be placed in an adaptive support body, and the copper core of the cable can be supported by the first connector and the second connector, while the outer cable body, the supporting flexible strip, the first connector and the second connector protect the copper core of the cable. At the same time, the heat generated by the copper core of the cable during operation can be discharged through the heat dissipation holes.

[0015] 2. When the outer cable body of the present invention is impacted, the force-bearing point deforms and transmits the impact force to the first and second blocks. When the first and second blocks are deformed by the impact force, they can squeeze the adjacent dislocation cavities against each other, so that the first and second blocks can be displaced relative to each other when subjected to force, thereby transmitting the impact force received by the cable and avoiding damage to the cable due to a large load at a certain point.

[0016] 3. The first block and the second block of the present invention can squeeze each other when they are displaced. The tops of the first block and the second block will be subjected to compression, while the bottoms of the first block and the second block will be subjected to tension, so as to reduce the pressure borne by each first block and the second block so that it will not be concentrated on a certain point, thereby reducing the bearing capacity of a single structure, effectively improving the deformation resistance of the cable, and avoiding the cable from breaking due to excessive pressure.

[0017] 4. The present invention fills the supporting soft strip with the first rubber column and the second rubber column and the non-Newtonian fluid filling body, so that the fluid in the non-Newtonian fluid filling body becomes more viscous and compact, thereby improving the impact resistance of the device. Moreover, the setting of the reinforcing sleeve can effectively improve the deformation resistance of the supporting soft strip, thereby preventing the cable from being damaged by excessive impact force.

[0018] 5. The first connector and the second connector of the present invention can be installed together in an end-to-end butt-jointed manner through the second annular groove and the first annular groove, which facilitates the first connector and the second connector to perform adaptive angle adjustment when the cable is bent. The second annular groove and the first annular groove not only ensure that the first connector and the second connector are butt-jointed and installed together, but also limit the angles of the adjacent first connector and the second connector when they are adjusted, thereby avoiding the tension generated by the deformation of the cable at the bend causing the protective performance at the bend to decrease, thereby improving the anti-bending performance of the cable.

[0019] To sum up, the overall design is simple and the structure is reasonable. Through the corresponding coordination of various structures, the copper core of the cable is supported by the first connector and the second connector, which makes it easy for the cable to bend. The first connector and the second connector can perform adaptive angle adjustment to avoid the tension generated by the deformation of the cable at the bend, which causes the protective performance at the bend to deteriorate, thereby improving the anti-bending performance of the cable. The first rubber column and the second rubber column and the non-Newtonian fluid filler filled in the support strip make the fluid in the non-Newtonian fluid filler more viscous and compact, thereby improving the impact resistance of the device. In addition, the reinforcement sleeve can effectively improve the deformation resistance of the support strip, thereby avoiding damage and breakage of the cable due to excessive impact force.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0033] As attached Figure 1-8 The shown is a cable for new energy vehicles that is anti-breaking. The copper core of the cable is supported by the first connector 301 and the second connector 302 through a pressure-resistant protection component arranged on the outer cable body 1. When the cable is bent, the first connector 301 and the second connector 302 can perform adaptive angle adjustment to avoid the tension generated by the deformation of the cable at the bend causing the protection performance at the bend to deteriorate, thereby improving the anti-bending performance of the cable. The first rubber column 201 and the second rubber column 202 and the non-Newtonian fluid filling body 203 filled in the support soft strip 2 make the fluid in the non-Newtonian fluid filling body 203 more viscous and compact, thereby improving the impact resistance of the device. In addition, the setting of the reinforcement sleeve 204 can effectively improve the deformation resistance of the support soft strip 2, thereby preventing the cable from being damaged and broken due to excessive impact force. The specific structural setting of the component is as follows.

[0034] The compression protection component includes a supporting soft strip 2 arranged in the outer cable body 1, and a plurality of first blocks 101 for support are arranged on the outside of the supporting soft strip 2, and a second block 102 for support is arranged on one side of the multiple first blocks 101, and two deformable supporting ribs 104 are arranged on the multiple first blocks 101 and the second blocks 102, and each first block 101 and the second block 102 are slidably connected to the supporting rib 104, and a dislocation cavity 103 for dislocation is formed between multiple adjacent two first blocks 101 and the second blocks 102, and a limiting arc groove 105 matching the supporting soft strip 2 is opened on the side of the first block 101 and the second block 102 facing the supporting soft strip 2, and the vertical cross-sectional shape of the limiting arc groove 105 is set to an arc shape, and the vertical cross-sectional shape of the first block 101 and the second block 102 is set to a trapezoidal shape, and the trapezoidal cross-sections of each first block 101 and the second block 102 are relatively arranged.

[0035] A plurality of deformable first rubber columns 201 are provided inside the support soft strip 2, and a deformable second rubber column 202 is provided on each first rubber column 201. An inner lining 205 is provided inside the support soft strip 2 and on the outside of the second rubber column 202 and the first rubber column 201. The interior of the inner lining 205 is filled with a non-Newtonian fluid filler 203. A reinforcement sleeve 204 for protection is provided on the surface of the support soft strip 2. The reinforcement sleeve 204 includes a plurality of high-strength and high-modulus polyethylene fiber filaments, and the high-strength and high-modulus polyethylene fiber filaments are staggered.

[0036] The supporting strip 2 is provided with an adaptive support body 3 for protecting the wire on one side away from the first block 101 and the second block 102. The adaptive support body 3 includes a plurality of first connectors 301 and second connectors 302 arranged side by side. The outer sides of the first connector 301 and the second connector 302 are provided with heat dissipation holes 308 for heat dissipation. The first connector 301 and the second connector 302 are arranged end to end relative to each other. The top and bottom of the first connector 301 and the second connector 302 are provided with reinforcement members 303 for protection. The first connector 301 and the second connector 302 are respectively detachably connected to the corresponding reinforcement members 303. One end of the first connector 301 and the second connector 302 First annular grooves 304 for limiting are provided on both sides of the surfaces of the first connecting member 301 and the second connecting member 302, and second annular grooves 305 are provided on the other ends of the first connecting member 301 and the second connecting member 302 and on both sides of the inner walls of the first connecting member 301 and the second connecting member 302. Transition arc slopes are provided at both ends of the first connecting member 301 and the second connecting member 302. The vertical cross-sectional shapes of the first annular groove 304 and the second annular groove 305 are both set to be arc-shaped. The first annular groove 304 and the second annular groove 305 match each other. A center hole 306 for limiting is provided through the inner wall of the second annular groove 305, and a connecting column 307 matching the center hole 306 is provided on the inner wall of the second annular groove 305.

[0037] According to the above structure, when the cable manufactured by the present invention is in use, the copper core of the cable can be placed in the adaptive support body 3, and the copper core of the cable is supported by the first connector 301 and the second connector 302, while the outer cable body 1, the support strip 2, the first connector 301 and the second connector 302 protect the copper core of the cable. At the same time, the heat generated by the copper core of the cable during operation can be discharged through the heat dissipation holes 308;

[0038] At the same time, when the cable is impacted by an external force, the force-bearing point deforms and transmits the impact force to the first block 101 and the second block 102. When the first block 101 and the second block 102 are deformed by the impact force, they can squeeze the adjacent dislocation cavities 103 against each other, so that the first block 101 and the second block 102 can be displaced relative to each other when subjected to force, thereby transmitting the impact force on the cable and avoiding damage to the cable due to a large load at a certain point.

[0039] And through the trapezoidal cross-section of the first block 101 and the second block 102, the first block 101 and the second block 102 can squeeze each other when they are displaced, and the tops of the first block 101 and the second block 102 will be subjected to compression, while the bottoms of the first block 101 and the second block 102 will be subjected to tension, so as to reduce the pressure on each first block 101 and the second block 102 so that it will not be concentrated on a certain point, thereby reducing the bearing capacity of a single structure, which can effectively improve the deformation resistance of the cable and avoid the cable from breaking due to excessive pressure.

[0040] The first rubber column 201 and the second rubber column 202 and the non-Newtonian fluid filling body 203 filled in the supporting soft strip 2 make the fluid in the non-Newtonian fluid filling body 203 become more viscous and compact, thereby improving the impact resistance of the device. In addition, the setting of the reinforcement sleeve 204 can effectively improve the deformation resistance of the supporting soft strip 2, thereby preventing the cable from being damaged by excessive impact force.

[0041] And when the cable is being assembled, the first connector 301 and the second connector 302 can be installed together in an end-to-end manner through the second annular groove 305 and the first annular groove 304, and can also rotate through the center hole 306 and the axis point of the connecting column 307, so that when the cable is bent, the first connector 301 and the second connector 302 can perform the function of adaptive angle adjustment. The second annular groove 305 and the first annular groove 304 not only ensure that the first connector 301 and the second connector 302 are butt-jointed and installed together, but also can limit the angle adjustment of the adjacent first connector 301 and the second connector 302, thereby avoiding the tension generated by the deformation of the cable bending part causing the protective performance of the bending part to become lower, thereby improving the anti-bending performance of the cable.

[0042] Different from the prior art, the present application discloses a cable for new energy vehicles that is anti-breaking. The copper core of the cable is supported by the first connector 301 and the second connector 302, so that when the cable is bent, the first connector 301 and the second connector 302 can perform adaptive angle adjustment to avoid the tension generated by the deformation of the cable at the bend causing the protective performance at the bend to deteriorate, thereby improving the anti-bending performance of the cable. The first rubber column 201 and the second rubber column 202 and the non-Newtonian fluid filling body 203 filled in the support soft strip 2 make the fluid in the non-Newtonian fluid filling body 203 become more viscous and compact, thereby improving the impact resistance of the device. In addition, the reinforcement sleeve 204 can effectively improve the deformation resistance of the support soft strip 2, thereby preventing the cable from being damaged and broken due to excessive impact force.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
