Description

Technical Field

[0001] The present invention relates to the field of charging cables, and in particular to a new energy vehicle charging cable and a method for using the same. Background Art

[0002] With the increasing attention paid to environmental protection and the gradual scarcity of oil resources around the world, the development of new energy vehicles (such as electric vehicles and hybrid vehicles) has become an important trend in the global automotive industry. New energy vehicles not only help reduce carbon emissions, but also promote the optimization and sustainable development of energy structure. In this context, new energy vehicle charging cables are particularly important as key components connecting new energy vehicles and charging facilities. New energy vehicle charging cables are current carriers that connect electric vehicles to charging piles or charging guns, and are responsible for the transmission of electrical energy and signal control.

[0003] Some of the existing new energy vehicle charging cables have liquid cooling function, but when the cable is cut and needs to be connected, the internal liquid circuit is not convenient to connect, and the cable joints will become loose as the material ages. Summary of the invention

[0004] Based on this, the purpose of the present invention is to provide a new energy vehicle charging cable and a method of using the same, so as to solve the technical problem that a part of the existing new energy vehicle charging cables have liquid cooling function, but when the cable is cut and needs to be connected, the internal liquid circuit is not convenient to connect, and the cable joints will become loose as the material ages.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a new energy vehicle charging cable, comprising a cable body, an end and a joint, a water pipe is arranged inside the cable body, and a spirally wound multi-strand wire core is arranged between the cable body and the water pipe, and a plurality of water channels are opened on the wall thickness of the cable body, the end of the end is connected to an inner plate through a plurality of connecting columns, a cable channel for the wire core to pass through is arranged on the inner plate, a water flow gap is arranged between adjacent cable channels, and the water channel and the water flow gap are matched, a channel is arranged in the middle of the inner plate, and a water through hole connected to the water flow gap is arranged on the channel, one end of the water through hole is connected to a circle of elastic inner card plate, the water pipe is threadedly sleeved on one end of the channel and presses the inner card plate inwardly, the gap between the end and the inner plate is a second connecting groove, and a circle of elastic outer card plate is arranged at one end of the inner ring of the second connecting groove, and one end of the cable body is threadedly sleeved into the interior of the second connecting groove and presses the outer card plate inwardly.

[0006] By adopting the above technical scheme, a water channel is arranged on the cable body, a water pipe is arranged inside the cable body, a spirally wound wire core is provided between the cable body and the water pipe, water flows in the water channel, and the water flows into the water pipe through the structure inside the terminal, thereby realizing the circulation of water, and the heat generated when the cable is charged is taken away by the water flow, thereby slowing down the aging of the cable. The terminal is connected to the cable body through an outer card plate, and is connected to the water pipe through an inner card plate. The inner and outer card plates are elastic, and the inner and outer card plates will be squeezed after the cable body and the water pipe are plugged in. As the cable ages and softens, the inner and outer card plates use their own elasticity to embed into the cable body and the water pipe, thereby strengthening the connection with the terminal and preventing the terminal from loosening.

[0007] The present invention is further configured as follows: an inner retaining ring is movably connected inside the channel, and the inner retaining ring cooperates with the water through hole, the other end of the inner retaining ring is connected to the extrusion plate through a connecting rod, and a second spring is connected between the extrusion plate and the inner plate, the other end of the inner plate is provided with an inner through groove for the inner retaining ring to pass through, an outer retaining ring is movably connected in the interlayer between the end head and the inner plate, the other end of the inner plate is provided with an outer through groove for the outer retaining ring to pass through, a first spring is connected between the outer retaining ring and the inner plate, a first connecting groove is provided at one end of the end head away from the second connecting groove, the outer retaining ring extends into the first connecting groove, the joint is threadedly inserted into the interior of the first connecting groove, a connecting pipe is also provided inside the joint, a limiting pipe is extended to the rear of the channel, the extrusion plate extends into the limiting pipe, and the connecting pipe is threadedly connected to the interior of the limiting pipe.

[0008] By adopting the above technical solution and setting structures such as an outer retaining ring and an inner retaining ring, when the cable is cut and wiring is required, the outer retaining ring and the inner retaining ring can be squeezed to block the water channel inside the end, and the water channel of the cable at the other end and the main part of the cable are connected through the joint, thereby facilitating the connection of the internal liquid path.

[0009] The present invention is further configured such that a groove for avoiding the connecting column is provided on the outer retaining ring.

[0010] By adopting the above technical solution, a movable space is provided for the movement of the outer retaining ring.

[0011] The present invention is further configured such that protrusions are provided on the outer sides of the inner and outer clamping plates, and the inner and outer clamping plates are configured to be tilted upwards.

[0012] By adopting the above technical solution, the firmness of the connection with the water pipe and the cable body is increased by the protrusion.

[0013] The present invention is further configured such that a first push block is arranged in the interlayer at one end of the joint, and a second push block is arranged in the interlayer at one end of the pipe.

[0014] By adopting the above technical solution, the outer stop ring is pushed to move by the first push block, and the extrusion plate is pushed to move by the second push block.

[0015] The present invention is further configured such that the inner end edge of the outer retaining ring is provided with a limiting plate that cooperates with the outer through groove, and the inner retaining ring is provided with a limiting structure that cooperates with the inner through groove.

[0016] By adopting the above technical solution, the movement of the outer retaining ring and the inner retaining ring is limited to prevent them from falling off.

[0017] The present invention also provides a method for using a new energy vehicle charging cable, and the method for using is as follows:

[0018] Step 1: By connecting the water channel and the water pipe of the liquid cooling circulation system, the water channel and the water flow gap form a match, and the liquid enters the water channel for circulation. When the liquid flows to the end position, the liquid enters the channel through the water flow gap and the water hole, and then enters the water pipe for reflux, and heat exchange is carried out in this cycle;

[0019] Step 2: With the external environmental factors and the use of the cable itself, the cable body will gradually age and become soft after aging. At this time, the outer card will be embedded into the cable body when it is reset, and there are protrusions on the outside of the outer card. These protrusions will be embedded deeper, thereby strengthening the connection between the cable body and the end, so that the end is not easy to fall off after the cable body ages. The same principle is also used between the channel and the water pipe, and the inner card is used to squeeze into the water pipe to strengthen the connection;

[0020] Step three: when wiring is required, connect the connector to the end, and after the wire cores are connected, screw the connector thread into the first connecting groove. During the screwing-in process, the outer baffle ring is squeezed by the first push block, and the outer baffle ring is retracted inward and squeezes the first spring, so that the outer baffle ring coincides with the water flow gap, thereby blocking the water flow gap. Then the connecting pipe thread is connected to the limiting pipe. During the screwing-in process of the connecting pipe, the extrusion plate and the second spring are squeezed by the second push block. The extrusion plate pushes the inner baffle ring to move through the connecting rod, so that the inner baffle ring coincides with the water hole, thereby further blocking the water flow. Then the water in the water hole can enter the interlayer in the connector through the outer groove, and the interlayer in the connector is connected to the new cable. The water flow in the connector interlayer circulates in the waterway flowing into the new cable, and the water flow in the connecting pipe enters the limiting pipe and the connecting pipe through the inner groove. The connecting pipe is connected to the water pipe of the new cable, thereby realizing the connectivity of the water flow.

[0021] In summary, the present invention mainly has the following beneficial effects:

[0022] 1. The present invention arranges a water channel on the cable body, arranges a water pipe inside the cable body, and a spirally wound wire core is arranged between the cable body and the water pipe. Water flows through the water channel, and the water flows into the water pipe through the structure inside the end, thereby realizing water circulation. The heat generated by the cable during charging is taken away by the water flow, thereby slowing down the aging of the cable.

[0023] 2. The present invention sets an end, which is connected to the cable body through an outer card plate and to the water pipe through an inner card plate. The inner and outer card plates are elastic and will squeeze the inner and outer card plates after the cable body and the water pipe are plugged in. As the cable ages and softens, the inner and outer card plates use their own elasticity to embed into the cable body and the water pipe, thereby strengthening the connection with the end, avoiding the end from loosening and increasing the service life.

[0024] 3. The present invention provides structures such as an outer retaining ring and an inner retaining ring. When the cable is cut and needs to be connected, the outer retaining ring and the inner retaining ring are squeezed to block the water passage inside the end. The water passage of the other end of the cable and the main part of the cable are connected through a joint, which facilitates the connection of the internal liquid circuit.

DETAILED DESCRIPTION

[0042] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] The following describes an embodiment of the present invention based on its overall structure.

The water pipe 2 is threadedly sleeved on one end of the channel 30 and presses the inner clamping plate 20 inward. The gap between the end 5 and the inner plate 7 is a second connecting groove 31, and one end of the inner ring of the second connecting groove 31 is provided with a circle of elastic outer clamping plate 21. One end of the cable body 1 is threadedly sleeved into the interior of the second connecting groove 31 and presses the outer clamping plate 21 inward. The inner clamping plate 20 and the outer clamping plate 21 are arranged to be tilted upward.

[0045] Some existing new energy vehicle charging piles are equipped with a liquid cooling circulation system. The liquid cooling circulation system connects the water channel 4 and the water pipe 2, and the water channel 4 cooperates with the water flow gap 9. The liquid enters the water channel 4 for circulation. When the liquid flows to the end 5, the liquid enters the channel 30 through the water flow gap 9 and the water hole 10, and then refluxes into the water pipe 2. In this way, heat exchange is carried out in a cycle, and the heat generated by the wire core 3 during the charging process is taken away by the water flow, thereby slowing down the aging of the cable.

[0046] With the external environmental factors and the cable body's own usage, the cable body 1 will gradually age and become soft after aging. At this time, the outer card plate 21 will be embedded into the cable body 1 when it is reset, and protrusions 22 are also provided on the outer side of the outer card plate 21. These protrusions 22 will be embedded deeper, thereby strengthening the connection between the cable body 1 and the terminal 5, so that the terminal 5 is not easy to fall off after the cable body 1 is aged. The same principle is also used between the channel 30 and the water pipe 2, and the inner card plate 20 is used to squeeze the water inlet pipe 2 to strengthen the connection.

The other end of the inner retaining ring 15 is connected to the extrusion plate 16 through the connecting rod 18, and the second spring 17 is connected between the extrusion plate 16 and the inner plate 7. The other end of the inner plate 7 is provided with an inner groove 29 for the inner retaining ring 15 to pass through. The outer retaining ring 11 is movably connected in the interlayer between the end 5 and the inner plate 7. The outer retaining ring 11 is provided with a groove 12 for avoiding the connecting column 6. The other end of the inner plate 7 is provided with an outer groove 28 for the outer retaining ring 11 to pass through. The first spring 13 is connected between the outer retaining ring 11 and the inner plate 7, and the end 5 is away from the second connecting groove 31. A first connecting groove 23 is provided at one end, the outer retaining ring 11 extends into the first connecting groove 23, the joint 24 is threadedly inserted into the first connecting groove 23, a connecting pipe 25 is also provided inside the joint 24, a limiting pipe 32 is extended to the rear of the channel 30, the extrusion plate 16 extends into the limiting pipe 32, the connecting pipe 25 is threadedly connected to the inside of the limiting pipe 32, the inner end edge of the outer retaining ring 11 is provided with a limiting plate 14 that cooperates with the outer through groove 28, and the inner retaining ring 15 is provided with a limiting structure 19 that cooperates with the inner through groove 29. In the initial state, the inner retaining ring 15 is staggered with the water through hole 10, and the outer retaining ring 11 is also staggered with the water flow gap 9.

[0048] When wiring is required, the connector 24 is connected to the end 5. After the wire core 3 is docked, the connector 24 is screwed into the first connecting groove 23. A first push block 26 is provided in the interlayer at one end of the connector 24. During the screwing process, the outer retaining ring 11 is squeezed by the first push block 26, and the outer retaining ring 11 is retracted inward and squeezes the first spring 13, so that the outer retaining ring 11 coincides with the water flow gap 9, thereby blocking the water flow gap 9. Then, the pipe 25 is threadedly connected into the limit tube 32. A second push block 27 is provided in the interlayer at one end of the pipe 25. During the screwing process of the pipe 25, the second push block 2 7 squeezes the squeezing plate 16 and squeezes the second spring 17. The squeezing plate 16 pushes the inner retaining ring 15 to move through the connecting rod 18, so that the inner retaining ring 15 overlaps with the water through hole 10, thereby further blocking the water flow. Then the water in the water through hole 10 can enter the interlayer in the joint 24 through the outer groove 28. The interlayer in the joint 24 is connected to the new cable. The water flow in the interlayer of the joint 24 circulates in the waterway flowing into the new cable. The water flow in the connecting pipe 25 will enter the limiting pipe 32 and the connecting pipe 25 through the inner groove 29.
