Charging pile cables can realize information transmission and data interaction, effectively ensuring the stability and safety of charging piles and the use of electric vehicles;

[0003] However, most of the current charging cables used in charging piles do not have active heat dissipation functions. Therefore, when charging for a long time, the temperature of the cable is often too high, affecting safety. The inability to actively dissipate heat can also easily affect the service life of the cable.

[0004] Therefore, how to provide a charging cable for a charging pile with efficient heat dissipation is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0005] One purpose of the utility model is to provide a charging cable for a charging pile with efficient heat dissipation. The utility model can realize the circulation of air inside the rubber sleeve, so as to quickly realize the heat dissipation of the inner cable, so that the temperature of the surface of the inner cable drops rapidly, the heat dissipation speed is fast, the efficiency is high, and the pressure resistance effect is good when in use. Dust and rain will not enter the inside of the rubber sleeve, and it is safe and reliable.

[0006] According to an embodiment of the utility model, a charging cable for a charging pile with high efficiency in heat dissipation comprises a rubber sleeve and an inner cable;

[0007] Buffer strips are fixedly installed around the inside of the rubber sleeve, and inner cables are fixedly installed on the inner side of each group of buffer strips. A cavity for ventilation and heat dissipation is formed between the inner cable and the rubber sleeve. Air outlet holes are opened around one end of the rubber sleeve, and a heat sink is installed on the other end of the rubber sleeve. Air inlets are installed around the heat sink, and a heat dissipation fan is fixedly installed inside the air inlet.

[0008] Furthermore, the outer wall of the inner cable is integrally formed with a plurality of groups of heat-conducting sheets protruding outward.

[0009] Furthermore, a one-way valve is fixedly installed inside the air outlet, and one end of the one-way valve facing the inside of the rubber sleeve is an air inlet end.

[0010] Furthermore, three groups of wire cores are installed inside the inner cable, and the three groups of wire cores are respectively a positive power line, a negative power line and a ground line.

[0011] Furthermore, the interior of the inner cable and around each group of wire cores are filled with cable fillers.

[0012] Furthermore, a protective net is fixedly installed inside the air inlet and outside the heat dissipation fan.

[0013] The beneficial effects of the utility model are:

[0014] The utility model can blow air into the rubber sleeve when the heat dissipation fan is started. At this time, the air can flow in the cavity and finally be discharged through the one-way valve in the air outlet to realize circulation. At this time, the heat dissipation of the inner cable can be realized, and the heat dissipation effect is good. The problem of excessive temperature can be effectively solved. In addition, the arrangement of multiple groups of buffer strips can have good buffering capacity when squeezed, improve the overall pressure resistance of the cable, and effectively protect the internal core of the inner cable when squeezed. In addition, the design of the one-way valve can ensure exhaust while preventing external dust and rainwater from entering the rubber sleeve, thereby ensuring stable and reliable use.

[0021] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0022] refer to Figure 1 , a charging cable for a charging pile with high efficiency heat dissipation, comprising a rubber sleeve 1 and an inner cable 3;

[0023] Buffer strips 2 are fixedly installed around the inside of the rubber sleeve 1, and inner cables 3 are fixedly installed inside each group of buffer strips 2;

[0024] Among them, three groups of wire cores 4 are installed inside the inner cable 3, and the three groups of wire cores 4 are respectively a positive power line, a negative power line and a ground line;

[0025] Secondly, the inner cable 3 and around each group of wire cores 4 are filled with cable fillers 7;

[0026] In this embodiment, the charging cable is mainly composed of two parts: a rubber sleeve 1 and an inner cable 3, and the rubber sleeve 1 and the inner cable 3 are connected by a buffer strip 2. The buffer strip 2 has deformation ability, so it can play a buffering effect when squeezed, and can effectively protect the inner cable 3 and the internal wire core.

[0027] refer to Figure 1-4 A cavity 13 for ventilation and heat dissipation is formed between the inner cable 3 and the rubber sleeve 1. An air outlet 5 is provided around one end of the rubber sleeve 1. A heat sink 9 is installed on the other end of the rubber sleeve 1. The heat sink 9 and the rubber sleeve 1 are interconnected. An air inlet 10 is installed around the heat sink 9. A heat dissipation fan 11 is fixedly installed inside the air inlet 10.

[0028] Among them, the outer wall of the inner cable 3 is integrally formed with a plurality of groups of heat-conducting sheets 8 protruding outward, thereby increasing the heat dissipation surface area of ​​the inner cable 3 and thus improving the heat dissipation efficiency;

[0029] Secondly, a one-way valve 6 is fixedly installed inside the air outlet 5, and the end of the one-way valve 6 facing the inside of the rubber sleeve 1 is the air inlet end, so the air inside the rubber sleeve 1 can only be discharged to the outside through the one-way valve 6, but the outside air and rainwater cannot enter the inside of the rubber sleeve 1 through the one-way valve 6;

[0030] In addition, a protective net 12 is fixedly installed inside the air inlet 10 and outside the cooling fan 11, and the protective net 12 can effectively prevent dust and debris from entering the heat sink 9;

[0031] In this embodiment, when the charging cable is in use, the cooling fan 11 can be started to blow air into the rubber sleeve 1. At this time, the air can flow through each group of cavities 13 and finally be discharged through the one-way valve 6. Therefore, the hot air in the rubber sleeve 1 can be quickly discharged, and the internal air circulation flow is realized, thereby completing the heat dissipation work of the inner cable 3. Moreover, since the surface of the inner cable 3 is provided with a heat conductive sheet 8, the heat dissipation efficiency can be improved.

[0032] Working principle, firstly, the inner core 4 of the inner cable 3 near the heat sink 9 can be connected to the output end of the charging pile, and the inner core 4 at the other end of the inner cable 3 can be connected to the charging gun. When the charging cable is working, the cooling fan 11 can be turned on synchronously. At this time, when the core 4 is heated, its heat can be conducted through the inner cable 3 and the heat conductive sheet 8. After the cooling fan 11 is started, it can blow air into the rubber sleeve 1. At this time, the air flows in the cavity 13 and is finally discharged through the one-way valve 6 inside the air outlet 5, thereby realizing the cooling of the inner cable 3, effectively improving the heat dissipation efficiency of the charging cable when it is working, and avoiding high temperature.

[0033] It is understandable that the cooling fan in the present invention can be driven by an external power cord, and the cooling fan can be controlled by a main control system through programming, and its control principle can be realized by existing control technology. The model of the cooling fan is not limited to a single type and can be any type currently available on the market that is suitable for the present invention.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
