Description

Technical Field

[0001] The present invention relates to the field of new energy technology, and in particular to a low-temperature-resistant new energy vehicle charging cable. Background Art

[0002] A cable is a linear or ribbon-shaped electrical device used to transmit electrical energy, electrical signals or optical signals. It is usually composed of a conductor made of metal such as copper or aluminum with good conductivity, an insulating layer for isolation and a protective layer for protection. It can be divided into power, control, communication, signal cables, etc. according to its use, and can also be divided into different types such as low voltage and medium voltage according to voltage level.

[0003] In the field of new energy vehicles, in order to conveniently charge new energy vehicles, a dedicated new energy vehicle charging cable is required. However, in some extreme environments, when the temperature is severely low, ordinary new energy vehicle charging cables are prone to more failures. Therefore, a low-temperature resistant new energy vehicle charging cable is needed.

[0004] However, the existing low-temperature resistant new energy vehicle charging cable has the following shortcomings:

[0005] Currently, the low-temperature resistant new energy vehicle charging cables on the market all use thickened outer sheaths to reduce the heat transfer between the internal wire part of the cable and the outside world. The heat generated when the cable is working can be preserved for a long time, so that the cable transportation can be stable. However, when the charging cable is not used for a long time, the internal temperature of the cable is still too low, making the wire easy to break due to the low temperature, causing the risk of short circuit and increasing maintenance costs.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention drives the first gear to rotate by the motor when the temperature is low enough, and the four traveling wheels move on the rope through the gear transmission.

[0021] 2. When the temperature inside the cable of the device of the present invention is moderate, in order to ensure the stable operation of the heating mechanism and avoid external rupture of the cable, anti-sliding blocks are regularly laid on the surface of the outer skin, which can reduce the friction between the outer skin and the ground during violent dragging and extend its service life. The anti-roll groove on the inner side of the outer skin engages with the anti-roll layer to prevent the internal wires from rotating and twisting when the cable moves at multiple angles, further improving the durability of the cable. In addition, the spiral threaded wire inside has a slightly increased resistance due to its own shape, and the heat generated is retained by the insulation layer, so that the internal temperature of the cable is higher than the outside when it is idle, which is conducive to charging at any time and can avoid the wires from breaking due to low temperature and brittleness when stored. The fastening layer compresses the insulation layer to enhance the thermal insulation effect. The steel wire reinforcement mesh can also increase the overall tensile strength of the cable.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described implementation regulations are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] According to the overall content, in a low-temperature resistant new energy vehicle charging cable, the existing technology can insulate the cable. However, in actual use, since the existing technology all adopts a thickened outer sheath to reduce the heat transfer between the internal wire part of the cable and the outside world, the heat generated by the cable during operation can be preserved for a long time, thereby making the cable transportation stable. However, when the charging cable is not used for a long time, the internal temperature of the cable is still too low, and the wire will still become easy to break due to the low temperature, causing the risk of short circuit and increasing maintenance costs. In order to solve the problems of this prior art, the present invention is completed. The motor device 210 drives the traveling wheel 215 to rotate, so that the traveling wheel 215 can drive the heating coil 220 to move at various positions inside the cable, and cooperates with the fan 221 at the bottom of the heating coil 220 to blow the hot air heated by the heating coil 220 into the interior of the housing 209. After gathering inside the housing 209, the hot air is dispersed to the surroundings through the ventilation holes on the outside of the housing 209, thereby increasing the temperature of various parts of the cable to resist the negative effects of low temperature on the cable.

[0035] During the entire process, in conjunction with the protection mechanism 3, the shape of the threaded conductor 302 can slightly increase the overall resistance of the cable, so that the cable temperature can be slightly increased. In addition, when the inner conductor 1 is accidentally broken, the threaded conductor 302 can perform temporary emergency electrical transmission work. The anti-roll layer 308 can reduce the possibility of the inner conductor of the cable twisting and breaking, thereby further ensuring the operation of the temperature increase mechanism 2.

[0036] In an embodiment of the present invention, according to Figure 2-Figure 5 as well as Figures 8-10As shown, a low-temperature resistant new energy vehicle charging cable includes an inner conductor 1, a heating mechanism 2 and a protective mechanism 3.

The heating mechanism 2 includes a motor device 210, a traveling wheel 215 and a heating ring 220. The traveling wheel 215 is driven to rotate by the motor device 210, so that the traveling wheel 215 can drive the heating ring 220 to move at various positions inside the cable. The protective mechanism 3 includes a threaded conductor 302 and an anti-roll layer 308. The shape of the threaded conductor 302 itself can increase the overall resistance of the cable, so that the cable temperature can be increased. When the inner conductor 1 is accidentally broken, the threaded conductor 302 can perform temporary emergency electrical transportation work, and the anti-roll layer 308 8 can reduce the situation where the wires inside the cable are twisted and broken. The heating mechanism 2 also includes an insulation shell 201. The inner side of the insulation shell 201 is fixedly connected to multiple support frames 202. The outer sides of the multiple support frames 202 are provided with rotation grooves 203. The inner sides of the multiple rotation grooves 203 are rotatably connected to a rotating telescopic rod 204. The other ends of the multiple rotating telescopic rods 204 are rotatably connected to another group of support frames 202. The outer side of the support frame 202 is also provided with a fixed groove 205. The interior of the fixed groove 205 is provided with a rubber partition 222. The left and right sides of the rubber partition 222 are fixedly connected to the limiting strip 206. The other side of the rubber partition 222 is fixedly connected to a connecting rod 207. The remaining side of the rubber partition 222 is provided with a connecting groove 208. The connecting rod 207 is rotatably connected to the connecting groove 208, the interior of the support frame 202 is fixedly connected to the limiting frame 223, the interior of the limiting frame 223 is fixedly connected with a rope 224, the top of the rope 224 is provided with a shell 209, the shell 209 is fixedly connected to the motor device 210, and a plurality of heat dissipation holes are provided on the outside of the shell 209. The output end at the bottom of the motor device 210 is fixedly connected to the first gear 211, and the bottom inner side of the motor device 210 is rotatably connected to a plurality of rotating rods 225, the outer side of one side of the rotating rod 225 is fixedly connected to the third gear 213, the top of the third gear 213 is fixedly connected to the second gear 212, and the outer side of the other side of the rotating rod 225 is fixedly connected to the fourth gear 214, and the bottoms of the plurality of third gears 213 are all connected to the row The feed wheel 215 is fixedly connected, and a plurality of anti-slip strips 216 are fixedly connected to the outside of the traveling wheel 215. A fifth gear 217 is fixedly connected to the bottom of one side of the traveling wheel 215. The tops of the plurality of traveling wheels 215 are rotatably connected to a clamping frame 226. The traveling wheel 215 is arranged on the outside of the rope 224. The first gear 211 is engaged with the second gear 212. The plurality of third gears 213 are respectively engaged with the corresponding plurality of fourth gears 214. A sixth gear 218 is arranged on the outside of the fifth gear 217. The bottom of the sixth gear 218 is rotatably connected to a fixing frame 219. Both sides of the fixing frame 219 are fixedly connected to the inner side of the casing 209. The bottom of the fixing frame 219 is fixedly connected to the heating ring 220. The bottom of the fixing frame 219 is provided with a fan 221.The fan 221 passes through the fixing frame 219 and is fixedly connected to the sixth gear 218. The fan 221 is rotatably connected to the fixing frame 219.

[0037] The effect achieved by the entire embodiment is as follows: when the temperature is low enough, the motor device 210 is started to drive the first gear 211 to rotate, and the first gear 211 drives the two second gears 212 meshing therewith to rotate. At this time, the two second gears 212 rotate in the same direction, and at the same time, the third gear 213 below the second gear 212 rotates synchronously and drives the two fourth gears 214 meshing therewith to rotate. Due to the gear principle, the rotation direction of the two fourth gears 214 is opposite to the rotation direction of the two third gears 213, so the traveling wheel 215 on the third gear 213 and the traveling wheel 215 on the fourth gear 214 rotate in the opposite direction. A rope 224 is provided between the four traveling wheels 215, so the four traveling wheels 215 can move on the rope 224. The weight of the bottom of the casing 209 is greater than that of the top, so that the four traveling wheels 215 can always keep the top facing upward due to the principle of gravity. The clamping frame 226 can make the four traveling wheels 215 always lightly clamp the rope 224 while rotating, ensuring that the traveling wheels 215 and the rope 224 are always in a state of mutual friction, preventing the traveling wheels 215 from slipping and affecting the traveling work. The anti-slip strip 216 of the traveling wheel 215 can increase the friction between the traveling wheel 215 and the rope 224, further ensuring the movement of the traveling wheel 215. Multiple gears rotate with the casing 209 through the rotating rod 225, so that multiple gears can rotate stably. When the fan 221 is rotated, the heat generated by the heating coil 220 is driven to flow upward into the casing 209, and after being gathered in the casing 209, the heat is dissipated to the surrounding areas from the heat dissipation holes around the casing 209 due to atmospheric pressure. When the heat dissipated by multiple casings 209 intersects with each other, the heat will be dissipated from the multiple channels inside the support frame 202 to the inside of the insulation shell 201 until the temperature inside the insulation shell 201 rises to a suitable temperature. The temperature inside the cable ensures that the cable can still work normally in a low temperature environment. In order for the warming mechanism 2 not to affect the collection and use of the cable, the insulation shell 201 is made of rubber material, and the internal support frame 202 is divided into multiple, which are connected to each other through the rotation groove 203 and the rotating telescopic rod 204. With the elasticity of the rotation and telescopic itself, the multiple support frames 202 can be bent freely at multiple angles. In order for the heat inside the insulation shell 201 to be able to stably dissipate from the preset channels on the support frame 202, rubber partitions 222 are added between the multiple support frames 202. The properties of the material of the rubber partition 222 itself can also ensure that the multiple support frames 202 can be bent freely at multiple angles.

[0038] In some embodiments, according to Figure 1 as well as Figure 5-Figure 7As shown in the figure, the protective mechanism 3 also includes a cast skin 303, which is arranged on the outside of the threaded wire 302, and the threaded wire 302 is sleeved on the outside of the inner wire 1. The outer side of the cast skin 303 is sleeved with a thermal insulation layer 304, and the outer side of the thermal insulation layer 304 is sleeved with a fastening layer 305. The interior of the fastening layer 305 is fixedly connected with a steel wire reinforcement mesh 301, and the outer side of the fastening layer 305 is sleeved with an inner insulating layer 5, and the outer side of the inner insulating layer 5 is sleeved with an insulating layer. Layer 306, the outer side of the insulating layer 306 is fixedly connected to the anti-roll layer 308, the outer side of the anti-roll layer 308 is provided with an outer skin layer 307, the outer side of the outer skin layer 307 is fixedly connected with multiple anti-sliding blocks 309, the inner side of the outer skin layer 307 is provided with multiple anti-roll grooves, the anti-roll grooves are engaged with the anti-roll layer 308, the traveling wheel 215 is a concave wheel, and its concave vertical cutting radius is slightly larger than the vertical cutting radius of the rope 224, and the anti-slip strip 216 is consistent with the curved shape of the traveling wheel 215.

[0039] The effect achieved by the entire embodiment is: while the temperature inside the cable is moderate, in order to ensure the stable implementation of the heating mechanism 2 and avoid the external rupture of the cable affecting the stability and sealing of the cable, a layer of anti-sliding block 309 is laid on the outer skin layer 307. Since the highest point of the anti-sliding block 309 is higher than the outer skin layer 307, the friction between the outer skin layer 307 and the ground is reduced during the violent dragging of some people, thereby increasing the service life of the outer skin layer 307. On this basis, the engagement between the anti-roll groove on the inner side of the outer skin layer 307 and the anti-roll layer 308 avoids the situation where the internal wire rotates and twists inside the outer skin layer 307 when the cable is frequently moved at multiple angles during use, thereby further increasing the service life of the cable. At the same time, in order to reduce the burden on the heating mechanism 2, this charging In actual operation, the spirally threaded conductor 302 slightly increases the resistance when transporting electricity, generating heat. This heat exists between the inner conductor 1, the threaded conductor 302 and the insulation layer 304. The insulation layer 304 reduces the loss of heat, so that the internal temperature of the charging cable can still be higher than the outside of the cable when it is not used for a long time, so as to facilitate random preparation for the next charging work and prevent the internal conductor from becoming hard and brittle due to low temperature and breaking when the cable is stored and sorted. The fastening layer 305 fastens the insulation layer 304, so that the insulation layer 304 is appropriately compressed, further reducing the gap inside the insulation layer 304, and increasing the thermal insulation effect of the insulation layer 304. The steel wire reinforcement mesh 301 in the fastening layer 305 increases the tensile strength inside the entire cable.
