The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive.

[0039] In the embodiments of the application, the same reference signs represent the same parts, and for the sake of brevity, the detailed description of the same parts is omitted in different embodiments. It should be understood that the size of various components in the embodiments of the application shown in the drawings is only exemplary and should not constitute any limitation on the application.
[0040] "Multiple" appearing in this application refers to two or more (including two).
[0041] With the popularity of new energy vehicles and other electric vehicles powered by electric energy, the demand for fast charging of electric vehicles is increasing, so that the power of charging equipment is getting larger and larger. However, the size and heat of the charging cable in the charging equipment will also increase with the power, which is not conducive to the installation and use of the charging equipment.
[0042] Based on the above considerations, in order to better solve the problems of large size and large heat of the charging cable, the embodiment of the application provides a charging cable, which comprises: a sheath structure and a plurality of wire harness structures, the sheath structure is formed into a tubular structure, the plurality of wire harness structures are arranged in the sheath structure and extend along the length direction of the sheath structure, each wire harness structure comprises at least one wire core and an insulation layer arranged outside the at least one wire core, and a first medium flow channel is defined between the sheath structure and the wire harness structure, and the first medium flow channel has a first medium inlet and a first medium outlet at both ends of the length of the first medium flow channel.
[0043] In the above technical solution, the plurality of wire harness structures are arranged in the sheath structure, and the first medium flow channel is located in the empty space formed between the plurality of wire harness structures and the sheath structure, so that the heat exchange medium in the first medium flow channel can simultaneously contact the sheath structure and the plurality of wire harness structures, thereby facilitating the reduction of the working temperature of the sheath structure and the plurality of wire harness structures, and the first medium flow channel does not easily affect the arrangement of the plurality of wire harness structures in the sheath structure, so that the plurality of wire harness structures can more fully utilize the internal space of the sheath structure, thereby facilitating the miniaturization design of the charging cable.
[0044] Please refer to Figure 1 and Figure 2 In the embodiment of the application, the charging cable 1 comprises: a sheath structure 10 and a plurality of wire harness structures 20, the sheath structure 10 is formed into a tubular structure, the plurality of wire harness structures 20 are arranged in the sheath structure 10 and extend along the length direction of the sheath structure 10, each wire harness structure 20 comprises at least one wire core 22 and an insulation layer 24 arranged outside the at least one wire core 22, and a first medium flow channel 30 is defined between the sheath structure 10 and the wire harness structure 20, and the first medium flow channel 30 has a first medium inlet 32 and a first medium outlet 34 at both ends of the length of the first medium flow channel 30, so that the first medium inlet 32 is at one end of the length of the first medium flow channel 30, and the first medium outlet 34 is at the other end of the length of the first medium flow channel 30.
[0045] It can be seen that the sheath structure 10 is a tubular structure, which is relatively simple in structure and convenient to process and manufacture, and the tubular structure provides a relatively closed accommodation space for the plurality of wire harness structures 20, so that the external environment does not easily interfere with the normal work of the plurality of wire harness structures 20, thereby facilitating the improvement of the stability of the charging cable 1.
[0046] In addition, the first medium flow channel 30 is defined between the sheath structure 10 and the wire harness structure 20, that is, the first medium flow channel 30 is located in the empty space formed between the plurality of wire harness structures 20 and the sheath structure 10, so that the heat exchange medium in the first medium flow channel 30 can simultaneously contact the sheath structure 10 and the plurality of wire harness structures 20, or in other words, the plurality of wire harness structures 20 can be immersed in the heat exchange medium in the first medium flow channel 30, so that the heat exchange medium can absorb and take away the heat generated by the plurality of wire harness structures 20 during work, so that the plurality of wire harness structures 20 can maintain a relatively stable working temperature during work, which helps to improve the stability of the charging cable 1, and at the same time, the heat exchange medium can reduce the temperature of the sheath structure 10 during work, and inhibit the temperature rise of the sheath structure 10, so that the user will not feel overheated or scalded when touching the charging cable 1 during work, and the first medium flow channel 30 does not easily affect the arrangement of the plurality of wire harness structures 20 in the sheath structure 10, so that the plurality of wire harness structures 20 can more fully utilize the internal space of the sheath structure 10, facilitating the miniaturization design of the charging cable 1, and reducing the wire diameter (or the outer diameter of the charging cable 1).
[0047] In other words, compared with the related art, a communication pipe is further sleeved outside the wire harness structure to form a medium flow channel with the wire harness structure and the communication pipe, and the communication pipe occupies a certain space in the sheath structure, which may affect the arrangement of the wire harness structure in the sheath structure, and it is not easy to realize the miniaturization design of the charging cable, and the heat exchange medium in the medium flow channel is not easy to contact the sheath structure, which is not convenient for reducing the temperature of the sheath structure during work; the above-mentioned arrangement of the present application can realize the isolated full-immersion cooling (isolated immersion) arrangement of the wire core 22, which is convenient for greatly improving the cooling effect of the wire harness structure 20, and compared with the direct immersion cooling arrangement, the present application embodiment is helpful to improve the electrical conductivity problem, and the cross-sectional shape of the first medium flow channel 30 is not circular, which can fully utilize the space in the arrangement direction of the wire harness structure 20, and is helpful to reduce the size in the arrangement direction of the wire harness structure 20, thereby reducing the outer diameter of the charging cable 1. For example, taking the thickness D of the above-mentioned communication pipe as an example, the linear reduction of the charging cable 1 can be 2*D~4*D compared with the above-mentioned related art.
[0048] Among them, the wire harness structure 20 includes at least one wire core 22 and an insulating layer 24 sleeved outside the at least one wire core 22, and the insulating layer 24 can separate the wire core 22 from the first medium flow channel 30, so that the heat exchange medium cannot directly contact the wire core 22, so that the current in the wire core 22 cannot easily leak into the first medium flow channel 30, thereby improving the stability of the wire harness structure 20 during work. It can be seen that the wire core 22 serves as a conductor, and the above-mentioned arrangement realizes the insulation between the heat exchange medium in the first medium flow channel 30 and the wire core 22, so that the type requirement of the heat exchange medium in the first medium flow channel 30 can be reduced.
[0049] When the charging cable 1 is used in the charging device 3, the charging device 3 can be provided with a heat management module 70, and the first medium inlet 32 and the first medium outlet 34 can be in communication with the heat management module 70 to form a medium circulation flow path in which the heat exchange medium flows into the first medium flow channel 30 from the first medium inlet 32, exchanges heat with the wire harness structure 20, and then flows out of the first medium outlet 34. It can be seen that the arrangement of the first medium inlet 32 and the first medium outlet 34 facilitates the participation of the first medium flow channel 30 in forming the medium circulation flow path, realizing the circulation flow of the heat exchange medium. This dynamic process is conducive to making heat transfer more efficient and improving the problem of local overheating, and is conducive to improving the stability and reliability of the entire charging device 3.
[0050] It can be understood that in the embodiments of the present application, each of the first medium inlet 32 and the first medium outlet 34 can be directly or indirectly in communication with the heat management module 70; for example, the charging cable 1 includes a second medium tube 40 described below, one of the first medium inlet 32 and the first medium outlet 34 can be indirectly in communication with the heat management module 70 through the second medium flow channel 42, of course, if the charging cable 1 does not include the second medium tube 40, each of the first medium inlet 32 and the first medium outlet 34 can be directly in communication with the heat management module 70, but not limited thereto.
[0051] Please refer to Figure 1 and Figure 2 In some embodiments, the sheath structure 10 includes a sheath piece 12, and the sheath piece 12 is a piece of insulating material.
[0052] It can be seen that by arranging the sheath piece 12 as a piece of insulating material, even if the insulating layer 24 of the wire harness structure 20 is damaged and the current in the wire core 22 leaks through the heat exchange medium, the sheath piece 12 can still effectively reduce the possibility of current leakage to the outside, so that the outer surface of the sheath structure 10 is always in a non-charged state, improving the reliability of the charging cable 1 in operation.
[0053] In addition, by arranging the sheath piece 12 as a piece of insulating material, it is conducive to further reducing the limitation on the type of heat exchange medium in the first medium flow channel 30, i.e., the heat exchange medium can be selected to be a medium with conductivity and high heat exchange efficiency, such as a glycol solution with different proportions, to facilitate improving the heat exchange efficiency of the first medium flow channel 30.
[0054] Please refer to Figure 1 and Figure 2 In some embodiments, the sheath structure 10 further includes a first medium tube 14, the first medium tube 14 is arranged in the sheath piece 12, and the outer peripheral wall of the first medium tube 14 is attached to the inner peripheral wall of the sheath piece 12, and the inner peripheral wall of the first medium tube 14 participates in defining the first medium flow channel 30.
[0055] It can be seen that by sleeving the sheath member 12 on the outer circumferential wall of the first medium pipe 14, and sleeving the first medium pipe 14 on the plurality of wire harness structures 20, the structural strength of the charging cable 1 is facilitated to be improved, so that when the charging cable 1 is subjected to external impact, the sheath structure 10 is not easy to deform greatly, thereby affecting the structural stability of the wire harness structure 20.
[0056] In addition, the first medium flow channel 30 is located in the first medium pipe 14, so that the heat exchange medium in the first medium flow channel 30 can absorb and take away the temperature of the sheath member 12, so that the user touching the sheath member 12 will not feel overheating or scalding.
[0057] Among them, the first medium pipe 14 can also serve as an identification component, for example, after the charging cable 1 is used for a long time, wear and tear occurs, when the sheath member 12 is exposed due to wear and tear to the first medium pipe 14, the first medium pipe 14 can play a warning role, which is beneficial for the user to find that the wear and tear of the sheath member 12 of the charging cable 1 has exceeded the safe range, reminding the user to replace or repair the charging cable 1, thereby reducing the risk of charging wire harness leakage; in other words, the arrangement of the sheath member 12 and the first medium pipe 14 can provide double protection for the first medium flow channel 30, even if the sheath member 12 is worn out, the heat exchange medium in the first medium pipe 14 is not easy to leak, which is beneficial to improve the protection performance of the sheath structure 10. It can be understood that in order to facilitate the user to observe, the first medium pipe 14 is different from the sheath member 12, which can be different in material, shape or color, as long as the user can intuitively observe that the sheath member 12 sleeved on the first medium pipe 14 has been completely worn out and has safety hazards.
[0058] Please refer to Figure 1 and Figure 2In some embodiments, the charging cable 1 further comprises at least one second medium pipe 40, the second medium pipe 40 is arranged in the sheath structure 10 and extends along the length direction of the sheath structure 10, so that the first medium flow channel 30 is located between the sheath structure 10, the wire harness structure 20 and the second medium pipe 40, and the first medium flow channel 30 is located in the empty space formed by the cooperation of the sheath structure 10, the wire harness structure 20 and the second medium pipe 40, and the first medium flow channel 30 is located outside the second medium pipe 40. The second medium flow channel 42 is defined in the second medium pipe 40, and the second medium flow channel 42 has a second medium inlet 420 and a second medium outlet 422 at both ends of the length direction, and the second medium inlet 420 is communicated with the first medium outlet 34. By arranging the second medium pipe 40 in the sheath structure 10, the heat exchange medium after completing the heat exchange work can flow to the second medium inlet 420 through the first medium outlet 34, so that the flow path of the heat exchange medium in the charging cable 1 is more clear, and the heat exchange efficiency is improved. At this time, for the charging cable 1, the first medium flow channel 30 can be used as a liquid inlet flow channel, and the second medium flow channel 42 can be used as a liquid outlet flow channel. Of course, in other embodiments of the present application, the second medium outlet 422 is communicated with the first medium inlet 32, so that the heat exchange medium after cooling treatment can flow to the first medium inlet 32 through the second medium outlet 422 and enter the first medium flow channel 30 to participate in heat exchange. Similarly, the flow path of the heat exchange medium in the charging cable 1 is more clear, so that the working temperature of the charging cable 1 is maintained at a reasonable level, and the heat exchange efficiency is improved. At this time, for the charging cable 1, the second medium flow channel 42 is used as a liquid inlet flow channel, and the first medium flow channel 30 is used as a liquid outlet flow channel.
[0059] Obviously, in the above two schemes, whether the first medium flow channel 30 is used as a liquid inlet flow channel or the second medium flow channel 42 is used as a liquid inlet flow channel, the first medium flow channel 30 and the second medium flow channel 42 are arranged in series, and the heat exchange medium can flow through the above two flow channels in sequence. In addition, the arrangement of the second medium flow channel 42 makes the layout of the inlet and outlet of the flow channel structure composed of the first medium flow channel 30 and the second medium flow channel 42 more flexible, and facilitates the communication between the above flow channel structure and the external structure (such as the thermal management module 70 described herein).
[0060] Please refer to Figure 2 In some embodiments, the first medium inlet 32 and the second medium outlet 422 are located at the same end of the length direction of the sheath structure 10, and the end of the sheath structure 10 away from the first medium inlet 32 extends beyond the corresponding end of the second medium pipe 40, so that the first medium outlet 34 is communicated with the second medium inlet 420.
[0061] It can be seen that the first medium outlet 34 and the second medium inlet 420 are in communication, and thus the first medium inlet 32 can serve as an inlet of the flow channel structure formed by the first medium flow channel 30 and the second medium flow channel 42, and the second medium outlet 422 can serve as an outlet of the flow channel structure, so as to facilitate the flow channel structure to form a closed heat exchange flow channel with the external thermal management module 70, so that the heat exchange medium can circulate in the first medium flow channel 30 and the second medium flow channel 42, thereby helping to improve the heat exchange efficiency; since the first medium inlet 32 and the second medium outlet 422 are located at the same end of the sheath structure 10 in the length direction, the assembly of the flow channel structure and the thermal management module 70 is facilitated, and the assembly of the charging cable 1 and the thermal management module 70 is facilitated.
[0062] In addition, the communication between the first medium outlet 34 and the second medium inlet 420 is achieved by the misalignment of the corresponding end of the sheath structure 10 and the corresponding end of the second medium pipe 40, and the end of the second medium pipe 40 corresponding to the second medium inlet 420 does not protrude out of the sheath structure 10, so that it is not necessary to process a communication hole or the like on the sheath structure 10 and / or the second medium pipe 40, thereby facilitating the processing procedure of the charging cable 1.
[0063] Exemplarily, the sheath structure 10 includes a first end 16 and a second end 18 arranged opposite to each other in the length direction, the first medium outlet 34 and the second medium inlet 420 are located at the first end 16, the first medium inlet 32 and the second medium outlet 422 are located at the second end 18, and a refrigeration component (for example, the thermal management module 70 described below) is further arranged at the second end 18 of the sheath structure 10, so that the first medium inlet 32 and the second medium outlet 422 are indirectly connected through the refrigeration component, so that the heat exchange medium after completing heat exchange can be transmitted to the refrigeration component through the second medium outlet 422 for cooling again, and the cooled heat exchange medium can participate in heat exchange through the first medium inlet 32, thereby facilitating the formation of a circulating flow path in the sheath structure 10, and helping to improve the heat exchange efficiency.
[0064] Please refer to Figure 2 In some embodiments, the second medium inlet 420 is in communication with the first medium outlet 34, and the charging cable 1 further includes an adapter terminal 50, which is sealingly arranged at an end of the sheath structure 10 away from the first medium outlet 34, and the first medium inlet 32, the second medium outlet 422 and the wire harness structure 20 all pass through the adapter terminal 50.
[0065] It can be seen that by setting the adapter terminal 50 to seal the end of the sheath structure 10 away from the first medium outlet 34, the heat exchange medium is less likely to leak through the end away from the first medium outlet 34, facilitating the improvement of the stability of the charging cable 1 in operation. At the same time, the first medium inlet 32, the second medium outlet 422 and the wire harness structure 20 all pass through the adapter terminal 50, so that the first medium inlet 32, the second medium inlet 420 and the wire harness structure 20 are less likely to be disturbed by the sheath structure 10, providing greater operating space for the connection of the subsequent multiple wire harness structures 20 and other devices, facilitating the improvement of the flexibility of the charging cable 1, facilitating the realization of the switching of the first medium inlet 32, the second medium outlet 422 and the wire harness structure 20 at the adapter terminal 50, and facilitating the installation of the refrigeration component outside the charging cable 1 to indirectly connect the first medium inlet 32 and the second medium outlet 422 through the refrigeration component, thereby realizing the cooling treatment of the heat exchange medium flowing through the first medium inlet 32 and the second medium outlet 422, and facilitating the improvement of the heat exchange efficiency of the charging cable 1.
[0066] Please refer to Figure 1 In some embodiments, the plurality of wire harness structures 20 includes a charging positive wire harness 25, a charging negative wire harness 26, a ground wire harness 27 and a signal wire harness 28, each of the charging positive wire harness 25, the charging negative wire harness 26, the ground wire harness 27 and the signal wire harness 28 includes at least one wire core 22 and an insulating layer 24 sleeved outside the wire core 22; and / or the outer peripheral wall of each wire harness structure 20 is a cylindrical surface.
[0067] Each wire harness structure 20 is responsible for a specific current or signal transmission, such as the charging positive wire harness 25 transmitting positive power, the charging negative wire harness 26 transmitting negative power, the ground wire harness 27 ensuring system safety grounding, and the signal wire harness 28 being responsible for transmitting control signals or status information. This clear division of labor helps to reduce current interference and misoperation, improve the stability of the charging cable 1 in operation, and through the cooperation of multiple different types of wire harness structures 20, the charging cable 1 can realize reliable charging of the electric device, maintain the activity of the electric device and prolong the service life. At the same time, since the function of each wire harness structure 20 is clear, when the charging cable 1 fails, technicians can quickly locate the problem, reduce troubleshooting time and improve the maintenance efficiency of the charging cable 1.
[0068] By setting the outer peripheral wall of the wire harness structure 20 to be a cylindrical surface, there is always a certain empty space between the plurality of wire harness structures 20 to define at least part of the first medium flow channel 30, so that each wire harness structure 20 can be better contacted by the heat exchange medium, thereby effectively reducing the working temperature of the wire harness structure 20 and facilitating the improvement of the stability of the charging cable 1 in operation.
[0069] Please refer to Figure 1In some embodiments, the plurality of wire harness structures 20 includes a charging positive wire harness 25 and a charging negative wire harness 26, which are located on one of the longitudinal sections of the sheath structure 10, and the sheath structure 10 has a larger space at the longitudinal section so that the charging positive wire harness 25 and the charging negative wire harness 26 can fully utilize the internal space of the sheath structure 10, facilitating the miniaturization design of the charging cable 1 and appropriately reducing the outer diameter of the charging cable 1. For example, referring to Figure 1 The charging positive wire harness 25, the charging negative wire harness 26, and the sheath structure 10 are all circular in cross section, and the centers of the charging positive wire harness 25 and the charging negative wire harness 26 are located on the same diameter line of the sheath structure 10, so that the arrangement positions of the charging positive wire harness 25 and the charging negative wire harness 26 are more reasonable, facilitating the reduction of the outer diameter of the sheath structure 10 and the miniaturization design of the charging cable 1.
[0070] For example, referring to Figure 1 and Figure 2 In some embodiments, the charging cable 1 further includes at least one second medium pipe 40, which is arranged in the sheath structure 10 and extends along the length direction of the sheath structure 10, so that the first medium flow channel 30 is located between the sheath structure 10, the wire harness structure 20, and the second medium pipe 40, the second medium pipe 40 defines a second medium flow channel 42 in communication with the first medium flow channel 30 in series, and the second medium pipe 40 and the remaining wire harness structures 20 except the charging positive wire harness 25 and the charging negative wire harness 26 are respectively located on opposite sides of the above-mentioned one of the longitudinal sections of the sheath structure 10 (i.e., the longitudinal section where the charging positive wire harness 25 and the charging negative wire harness 26 are located).
[0071] By arranging the second medium pipe 40 and the remaining wire harness structures 20 except the charging positive wire harness 25 and the charging negative wire harness 26 on opposite sides of one of the longitudinal sections of the sheath structure 10, the second medium pipe 40 and the remaining wire harness structures 20 can effectively utilize the empty space between the sheath structure 10 and the charging positive wire harness 25 and the charging negative wire harness 26, so that the structure of the charging cable 1 is more compact, facilitating the miniaturization design of the charging cable 1, and the heat exchange medium in the first medium flow channel 30 can diffuse to the entire first medium flow channel 30 through the empty space between the plurality of wire harness structures 20, so that the heat exchange medium can effectively reduce the working temperature of the charging cable 1, thereby improving the working efficiency of the charging cable 1.
[0072] It can be understood that, in the above scheme, the second medium pipe 40 and the remaining harness structures 20 will occupy the space on the opposite sides of the longitudinal section, which does not mean that the second medium pipe 40 is on one side of the longitudinal section and the remaining harness structures 20 are on the other side of the longitudinal section, and is not limited to this layout; for example, there are two second medium pipes 40, and the two second medium pipes 40 are located on different sides of the above longitudinal section.

[0074] It can be seen that the outer diameter of the second medium pipe 40 (such as R1 in Figure 1 ) is greater than the outer diameter of the ground harness 27 (such as R2 in Figure 1 ) and the outer diameter of the signal harness 28 (such as R3 in Figure 1 ), and by arranging the ground harness 27 and the signal harness 28 on the different sides of the longitudinal section of the sheath structure 10 from the second medium pipe 40, the second medium pipe 40 with a larger size is arranged separately from the ground harness 27 and the signal harness 28 with smaller sizes, so that the ground harness 27, the signal harness 28 and the second medium pipe 40 can better utilize the empty space between the sheath structure 10 and the charging positive electrode harness 25 and the charging negative electrode harness 26, so that the internal structure of the charging cable 1 is more compact, and the miniaturization design of the charging cable 1 is facilitated.
