One end of the thermal deformation structure is connected to the inner sheath, and its other end abuts against the side of the electrical unit away from the central member. The thermal deformation structure is thermally coupled to the electrical unit, and the thermal deformation structure is configured to undergo elastic deformation upon heating, allowing the electrical unit to move to contact the inner sheath. The heat dissipation assembly is configured to dissipate heat from the electrical unit through the inner sheath.

[0006] In one possible implementation, the heat-deformation structure includes two bimetallic strip modules, which are spaced apart, and the electrical unit portion is located between the two bimetallic strip modules.

[0007] One end of the bimetallic strip module is connected to the inner sheath, and the other end abuts against the outside of the electrical unit.

[0008] In one possible implementation, the inner circumferential surface of the inner sheath is provided with a plurality of heat insulation portions, and the plurality of heat insulation portions are correspondingly arranged with the plurality of bimetallic strip modules. One end of the heat insulation portion is connected to the inner sheath, and the other end is connected to the end of the bimetallic strip module away from the electrical unit.

[0009] In one possible implementation, the inner circumferential surface of the inner sheath is provided with a plurality of first heat-conducting parts, and the plurality of first heat-conducting parts are correspondingly disposed with a plurality of heat-deformation structures, wherein the first heat-conducting parts are located between two bimetallic sheet modules of the corresponding heat-deformation structure.

[0010] Wherein, one side of the first heat-conducting part is connected to the inner sheath, and the other side of the first heat-conducting part is used to support the electrical unit. The heat dissipation assembly is configured to exchange heat with the electrical unit through the inner sheath and the first heat-conducting part.

[0011] In one possible implementation, the separator includes a first separator, a second separator, and a mounting portion. One end of the first separator is connected to the center member, the other end of the first separator is spaced apart from the second separator, and the end of the second separator away from the first separator is connected to the inner sheath.

[0012] The mounting portion is slidably connected to the first partition portion. The multi-core heat dissipation flexible cable also includes an optical unit. The mounting portion is configured to mount the optical unit. One end of the second partition portion is thermally coupled to the inner sheath, and the other end of the second partition portion is used for thermal coupling with the optical unit.

[0013] In one possible implementation, the multi-core heat dissipation flexible cable further includes a plurality of sliding components, which are correspondingly disposed with a plurality of the separators. The sliding components are connected to the support and are slidably connected to the first separator. The mounting portion is located on the sliding path of the sliding components, and the sliding components are configured to push the mounting portion to slide relative to the first separator.

[0014] In one possible implementation, the sliding assembly includes a first slider and a second slider.

[0016] In one possible implementation, the sliding assembly further includes a second elastic member, one end of which elastically abuts against the mounting portion to provide an elastic force to the mounting portion, the elastic force being configured to drive the mounting portion to slide toward a side closer to the center member.

[0017] The multi-core heat-dissipating flexible cable of this application features a thermal deformation structure that is thermally coupled to the electrical unit. The electrical unit is elastically connected to the central component. When the temperature of the electrical unit is low, the thermal deformation structure holds the electrical unit away from the inner sheath. When the electrical unit heats up, the thermal deformation structure undergoes elastic deformation, allowing the electrical unit to move towards the inner sheath until it contacts it. This allows the heat dissipation component to dissipate heat from the electrical unit through the inner sheath, preventing heat accumulation inside the cable at the electrical unit and avoiding premature cable aging.

[0027] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0028] like Figures 1 to 2 As shown, this embodiment provides a multi-core heat dissipation flexible cable 100, including an inner sheath 10, a heat dissipation component 20, a separator component 40, and multiple battery core components 50.

[0029] The inner sheath 10 is made of an insulating and thermally conductive material, such as by adding highly thermally conductive fillers (e.g., boron nitride, aluminum oxide, graphene, etc.) to the plastic material. The inner sheath 10 is generally a hollow cylindrical structure, and a receiving cavity 11 is provided inside the inner sheath 10.

[0030] The heat dissipation assembly 20 is arranged around the outer periphery of the inner sheath 10, and the heat dissipation assembly 20 is thermally coupled to the inner sheath 10. The partition assembly 40 is located within the receiving cavity 11, and includes a central member 41 and multiple partition members 42. The central member 41 is located at the center of the inner sheath 10, and is a hollow cylindrical structure made of insulating material such as plastic. Multiple partition members 42 are arranged around the outer periphery of the central member 41, and are arranged radially along the cable. One end of each partition member 42 is connected to the central member 41, and the other end is connected to the inner sheath 10. Any two adjacent partition members 42 are spaced apart to form a core cavity 110, thereby dividing the receiving cavity 11 into multiple core cavities 110. The number of core cavities 110 is the same as the number of partition members 42.

[0031] Multiple battery cell assemblies 50 are correspondingly arranged with multiple core cavities 110, and each battery cell assembly 50 is located within its corresponding core cavity 110. Each battery cell assembly 50 includes an electrical unit 51 and a thermal deformation structure 52. One side of the electrical unit 51 is elastically connected to a central member 41, and the electrical unit 51 is slidable relative to the central member 41. One end of the thermal deformation structure 52 is connected to an inner sheath 10, and its other end abuts against the side of the electrical unit 51 away from the central member 41. The thermal deformation structure 52 is thermally coupled to the electrical unit 51, and the thermal deformation structure 52 is configured to undergo elastic deformation upon heating, allowing the electrical unit 51 to move to contact the inner sheath 10. The heat dissipation assembly 20 is configured to dissipate heat from the electrical unit 51 through the inner sheath 10.

[0032] Thus, the multi-core heat dissipation flexible cable 100 of this application, by setting a heat deformation structure 52 and thermally coupling it with the electrical unit 51, and elastically connecting the electrical unit 51 with the central component 41, when the temperature at the electrical unit 51 is low, the heat deformation structure 52 holds the electrical unit 51 away from the inner sheath 10. After the electrical unit 51 heats up, the heat deformation structure 52 undergoes elastic deformation due to heat, thereby allowing the electrical unit 51 to move towards the side of the inner sheath 10 until it contacts the inner sheath 10, so that the heat dissipation component 20 dissipates heat from the electrical unit 51 through the inner sheath 10, avoiding the accumulation of heat inside the cable at the electrical unit 51, which would cause the cable to age too quickly and other effects.

[0033] Please combine Figures 2 to 3 In one embodiment, the electrical unit 51 includes a conductor 511 and an insulating layer 512 surrounding the conductor 511. The conductor 511 is made of a conductive metal such as copper, and the insulating layer 512 may be made of an insulating material.

[0034] The number of battery cell assemblies 50 is set to four, and each battery cell assembly 50 also includes a support member 53 and a first elastic member 54. One end of the support member 53 is used to support the battery cell 51, and the other end of the support member 53 is slidably connected to the center member 41. The first elastic member 54 is located between the support member 53 and the center member 41, and one end of the first elastic member 54 is elastically connected to the center member 41, and the other end is elastically connected to the support member 53.

[0035] Understandably, the number of battery cell assemblies 50 can also be set to three or five, or other quantities.

[0036] The outer periphery of the central component 41 is provided with a plurality of guide portions 411, the number of which is the same as the number of battery cell assemblies 50, i.e., four. The four guide portions 411 are arranged at equal intervals around the axis of the central component 41. The guide portions 411 are made of the same material as the central component 41, and the guide portions 411 and the central component 41 are integrally formed.

[0037] A guide groove 412 is provided at the end of the guide portion 411 away from the center member 41, and the guide groove 412 is arranged radially along the center member 41. The support member 53 includes an integrally formed sliding portion 532 and a support portion 531. Along the radial direction of the center member 41, one end of the sliding portion 532 is slidably disposed in the guide groove 412, and the support portion 531 is integrally formed at the end of the sliding portion 532 away from the center member 41. The support portion 531 has a generally arc-shaped structure so that the support portion 531 is disposed in close contact with the outer peripheral surface of the electrical unit 51, thereby improving the stability of the support portion 531 in supporting the electrical unit 51.

[0038] The first elastic element 54 is a spring, and its orientation is parallel to the extension direction of the guide groove 412. The first elastic element 54 is located within the guide groove 412, with one end elastically connected to the bottom wall of the guide groove 412 and the other end elastically connected to the end of the sliding part 532 located within the guide groove 412. The first elastic element 54 continuously provides an elastic force to the sliding part 532, allowing it to move away from the center member 41. Thus, when the thermal deformation structure 52 undergoes elastic deformation due to heat, allowing the electric unit 51 to move, the first elastic element 54 drives the electric unit 51 to contact the inner sheath 10. At this time, the heat dissipation assembly 20 can begin to operate, dissipating heat from the electric unit 51 in contact with the inner sheath 10 through the inner sheath 10.

[0039] It is understandable that a temperature-sensing optical fiber can be installed inside the inner sheath 10 to detect the ambient temperature inside the inner sheath 10, thereby controlling the working state of the heat dissipation component 20.

[0040] Please combine Figures 2 to 3 In one embodiment, the heat-deformable structure 52 includes two bimetallic strip modules 521, which are spaced apart, and the electrical unit 51 is partially located between the two bimetallic strip modules 521. One end of each bimetallic strip module 521 is connected to the inner sheath 10, and the other end abuts against the outer side of the electrical unit 51.

[0041] Two bimetallic strip modules 521 are arranged at an angle to each other, and the distance between the ends of the two bimetallic strip modules 521 closest to the inner sheath 10 is smaller than the distance between the ends of the two bimetallic strip modules 521 furthest from the inner sheath 10. The specific materials of the two metal strips of the bimetallic strip module 521 can be selected according to the actual situation; for example, the bimetallic strips can be made of brass / Invar alloy, etc. The two metal strips have different coefficients of thermal expansion, so that the bimetallic strip bends towards the side with the smaller coefficient of thermal expansion. In this configuration, the end of the metal sheet with a high coefficient of thermal expansion away from the inner sheath 10 contacts the outer surface of the electrical unit 51, while the metal sheet with a low coefficient of thermal expansion is located on the side of the metal sheet with a high coefficient of thermal expansion away from the electrical unit 51. After the heat from the electrical unit 51 is transferred to the bimetallic strip module 521, the end of the bimetallic strip module 521 away from the inner sheath 10 bends toward the side away from the electrical unit 51, thereby causing the ends of the two bimetallic strip modules 521 of the same heat deformation structure 52 away from the inner sheath 10 to open up to each other, thus providing space for the electrical unit 51 and allowing the electrical unit 51 to move toward the inner sheath 10, thereby enabling the electrical unit 51 to move to contact the inner sheath 10.

[0042] In this embodiment, the inner circumferential surface of the inner sheath 10 is provided with a plurality of heat insulation parts 12, and the plurality of heat insulation parts 12 are correspondingly arranged with a plurality of bimetallic strip modules 521. One end of the heat insulation part 12 is connected to the inner sheath 10, and the other end is connected to the end of the bimetallic strip module 521 away from the electrical unit 51.

[0043] The heat insulation part 12 is made of a heat-insulating and high-strength material to ensure that while providing heat insulation, it is not easily bent along with the bimetallic strip module 521. The heat insulation part 12 also serves to fix the bimetallic strip module 521 so that it can be bent with the end connected to the heat insulation part 12 as a reference.

[0044] In this embodiment, the inner circumferential surface of the inner sheath 10 is provided with a plurality of first heat-conducting parts 13, which are correspondingly arranged with a plurality of heat-deformation structures 52. The first heat-conducting parts 13 are located between two bimetallic strip modules 521 of their corresponding heat-deformation structures 52. One side of the first heat-conducting part 13 is connected to the inner sheath 10, and the other side of the first heat-conducting part 13 is used to support the electrical unit 51. The heat dissipation assembly 20 is configured to exchange heat with the electrical unit 51 through the inner sheath 10 and the first heat-conducting parts 13.

[0045] The first heat-conducting part 13 protrudes from the inner circumferential surface of the inner sheath 10 toward the center member 41, and the protrusion length of the first heat-conducting part 13 is greater than the protrusion length of the heat insulation part 12, so that after the two bimetallic strip modules 521 are bent, the electrical unit 51 can move smoothly to contact the first heat-conducting part 13 under the action of the elastic force of the first elastic member 54, so that the heat dissipation assembly 20 can dissipate heat to the electrical unit 51 through the inner sheath 10 and the first heat-conducting part 13.

[0046] The side of the first heat-conducting part 13 away from the inner sheath 10 can be configured as an arc-shaped surface to increase the contact area between the first heat-conducting part 13 and the electrical unit 51, thereby improving the heat dissipation effect on the electrical unit 51.

[0047] Thus, when the temperature of the electrical unit 51 rises to the point where the temperature of the bimetallic strip module 521 reaches the point where it bends and deforms, the two bimetallic strip modules 521 bend, causing the electrical unit 51 to move towards the first heat-conducting part 13 under the action of the first elastic member 54, until the electrical unit 51 contacts the first heat-conducting part 13. The heat dissipation assembly 20 then dissipates heat from the electrical unit 51, thereby lowering the temperature of the electrical unit 51. Subsequently, the temperature of the bimetallic strip module 521 decreases and resets, thereby pushing the electrical unit 51 toward the center member 41 so that the electrical unit 51 is no longer in contact with the first heat-conducting part 13. Thus, when heat dissipation is not required, the electrical unit 51 is in a non-contact state with the inner sheath 10, and the electrical unit 51 and the center member 41 are elastically connected through the first elastic member 54. The bimetallic strip module 521 supporting the electrical unit 51 also has the ability to undergo elastic deformation, which can improve the protection of the electrical unit 51. When the inner sheath 10 of the cable is compressed, it can provide buffer protection for the electrical unit 51 under the combined action of the first elastic member 54 and the bimetallic strip module 521, thereby avoiding the electrical unit 51 from being directly compressed and damaged.

[0048] Please combine Figures 2 to 3 In one embodiment, the separator 42 includes a first separator 421, a second separator 422, and a mounting portion 423. One end of the first separator 421 is connected to the center member 41, and the other end of the first separator 421 is spaced apart from the second separator 422. The end of the second separator 422 away from the first separator 421 is connected to the inner sheath 10. The mounting portion 423 is slidably connected to the first separator 421. The multi-core heat-dissipating flexible cable 100 also includes an optical unit 70. The mounting portion 423 is configured to mount the optical unit 70. One end of the second separator 422 is thermally coupled to the inner sheath 10, and the other end of the second separator 422 is used for thermal coupling with the optical unit 70.

[0049] The first partition 421 and the second partition 422 are arranged collinearly, and their extension directions are parallel to the radial direction of the central member 41. One end of the first partition 421 is integrally formed on the outer peripheral surface of the central member 41, and the other end of the first partition 421 is provided with a first sliding groove 4211. The mounting part 423 is generally annular in structure, forming a mounting cavity 4230 within the mounting part 423. The optical unit 70 is an optical fiber, and the optical unit 70 is disposed within the mounting cavity 4230 so that the optical unit 70 can move back and forth with the mounting part 423. A sliding protrusion 4231 protrudes from one end of the mounting part 423 near the first partition 421. The sliding protrusion 4231 is slidably disposed within the first sliding groove 4211 to realize that the mounting part 423 can slide back and forth along the extension direction of the first partition 421.

[0050] One end of the second partition 422 is integrally formed on the inner circumferential surface of the inner sheath 10, and the other end of the second partition 422 is provided with a second heat-conducting part 424. The second heat-conducting part 424, the second partition 422, and the inner sheath 10 are made of the same material to facilitate heat transfer between them. The second heat-conducting part 424 is used to contact the mounting part 423, and the mounting part 423 is made of the same material as the second heat-conducting part 424 and has a certain heat-conducting function. This allows the optical unit 70 to exchange heat with the second heat-conducting part 424 through the mounting part 423, thereby dissipating heat from the optical unit 70.

[0051] In this embodiment, the multi-core heat dissipation flexible cable 100 further includes multiple sliding components 60, which are correspondingly arranged with multiple separators 42. The number of sliding components 60 is the same as the number of separators 42. The sliding components 60 are connected to the support member 53 and are slidably connected to the first separator 421. The mounting part 423 is located on the sliding path of the sliding component 60, and the sliding component 60 is configured to push the mounting part 423 to slide relative to the first separator 421.

[0052] The sliding assembly 60 includes a first sliding member 61 and a second sliding member 62. Along the circumference of the center member 41, the first sliding member 61 and the second sliding member 62 are respectively disposed on opposite sides of the first partition portion 421. Both the first sliding member 61 and the second sliding member 62 are slidably connected to the first partition portion 421. The first sliding member 61 is movably connected to a nearby support member 53, and the second sliding member 62 is movably connected to a nearby support member 53. Both the first sliding member 61 and the second sliding member 62 are used to abut against the sliding of the mounting portion 423.

[0053] Along the outer periphery of the center member 41, a second groove 4214 is provided on one side of the first partition 421, and a third groove 4215 is provided on the other side of the first partition 421. Along the extending direction of the first partition 421, the second groove 4214 and the third groove 4215 are located on the side of the first groove 4211 away from the second partition 422, and the bottom wall of the first groove 4211 is provided with a first connecting hole 4212 and a second connecting hole 4213. The first groove 4211 is connected to the second groove 4214 through the first connecting hole 4212, and the first groove 4211 is connected to the third groove 4215 through the second connecting hole 4213.

[0054] The first sliding member 61 and the second sliding member 62 are generally elongated structures. The first sliding member 61 is slidably disposed in the second sliding groove 4214, and the second sliding member 62 is slidably disposed in the third sliding groove 4215. The end of the first sliding member 61 away from the center member 41 can extend into the first sliding groove 4211 through the first connecting hole 4212 and slide against the mounting part 423. The end of the second sliding member 62 away from the center member 41 can extend into the first sliding groove 4211 through the second connecting hole 4213 and slide against the mounting part 423. This allows the first sliding member 61 and the second sliding member 62 to drive the mounting part 423 to slide individually or simultaneously.

[0055] It is worth noting that when the bimetallic strip module 521 is in its natural state, both the first slider 61 and the second slider 62 are in contact with the mounting portion 423 but do not push the mounting portion 423 to move. When the electrical unit 51 corresponding to the support member 53 connected to the first slider 61 or the second slider 62 heats up, causing the bimetallic strip module 521 to undergo elastic deformation, the first slider 61 or the second slider 62 immediately pushes the mounting portion 423 to contact the second heat-conducting portion 424. While the heat dissipation assembly 20 dissipates heat from the electrical unit 51, it can also dissipate heat from the optical unit 70.

[0056] Furthermore, the optical unit 70 is located between the two electrical units 51. When the electrical unit 51 on either side of the optical unit 70 generates more heat, causing the temperature of the optical unit 70 to rise as well, the electrical unit 51 with higher heat generation will drive the optical unit 70 to slide synchronously through its corresponding slider when it moves.

[0057] It is understood that in other embodiments, when the bimetallic strip module 521 is in its natural state, both the first slider 61 and the second slider 62 are spaced apart from the mounting portion 423. That is, after the electrical unit 51 heats up to a certain temperature, causing the bimetallic strip module 521 to bend to a certain extent, the first slider 61 or the second slider 62 begins to slide to push the mounting portion 423 to move, and then the mounting portion 423 moves to contact the second heat-conducting portion 424 to dissipate heat from the optical unit 70. The distance between the first slider 61 and the second slider 62 and the mounting portion 423 can be set according to the temperature range in which the optical unit 70 needs to be cooled.

[0058] In this embodiment, the sliding assembly 60 further includes a first connector 63 and a second connector 64. One end of the first connector 63 is rotatably connected to the first slider 61, allowing the first connector 63 to deflect relative to the first slider 61. The other end of the first connector 63 is rotatably connected to the support member 53 corresponding to the first slider 61, allowing the first connector 63 to deflect relative to the support member 53. One end of the second connector 64 is rotatably connected to the second slider 62, and the other end is rotatably connected to the support member 53 corresponding to the second slider 62.

[0059] Both the first connector 63 and the second connector 64 adopt a linkage structure. The two ends of the first connector 63 are respectively hinged to the first slider 61 and the area of ​​the sliding part 532 exposed in the guide groove 412 in the core cavity 110, so that the support member 53 can drive the first slider 61 to slide through the first connector 63 or drive the second slider 62 to slide through the second connector 64 during the sliding process.

[0060] It is worth noting that the tilt angle of the first connector 63 relative to the support 53 and the first slider 61, as well as the length of the first connector 63, can be selected according to actual needs to ensure that the support 53 can drive the first slider 61 to slide when sliding. Correspondingly, the second connector 64 can be set with reference to the first connector 63.

[0061] In this embodiment, the sliding assembly 60 further includes a second elastic member 65, one end of which elastically abuts against the mounting portion 423 to provide an elastic force to the mounting portion 423. The elastic force is configured to drive the mounting portion 423 to slide toward the side closer to the center member 41.

[0062] The second elastic member 65 is provided along the extending direction of the second partition 422, and the second elastic member 65 is a spring. Along the circumference of the center member 41, the mounting portion 423 has a first mounting protrusion 4232 protruding on opposite sides, and the second partition 422 has a second mounting protrusion 4220 protruding on opposite sides. The two first mounting protrusions 4232 and the two second mounting protrusions 4220 are correspondingly provided. The second elastic member 65 is provided between the first mounting protrusion 4232 and its corresponding second mounting protrusion 4220. One end of the second elastic member 65 is elastically connected to the first mounting protrusion 4232, and the other end of the second elastic member 65 is elastically connected to the second mounting protrusion 4220. Thus, when the bimetallic strip module 521 resets and drives the first sliding member 61 and the second sliding member 62 to reset, the second elastic member 65 pushes the mounting part 423 to move toward the center member 41, thereby separating the mounting part 423 from the second heat-conducting part 424. This allows the optical unit 70 to be elastically connected to the inner sheath 10 through the second elastic member 65 when heat dissipation is not required, thereby preventing the inner sheath 10 from directly acting on the optical unit 70 when it is under pressure, which would cause damage to the optical unit 70.

[0063] Please combine Figure 4 In one embodiment, the heat dissipation component 20 employs an electrocooling structure and is thermally coupled to the inner sheath 10, thereby dissipating heat from the electrical unit 51 and the optical unit 70 through the inner sheath 10. The heat dissipation component 20 includes a hot-end layer 23, an electrocooling main body layer 22, and a cold-end layer 21. The electrocooling main body layer 22 is made of silicon-based materials or III-V group semiconductor materials, etc., and can achieve heat transfer based on the Peltier effect. When the electrocooling main body layer 22 is energized, it can transfer heat from the cold-end layer 21 to the hot-end layer 23. The electrocooling main body layer 22 can be externally connected to a power supply component via conductive wires to supply power to the electrocooling main body layer 22.

[0064] Both the hot end layer 23 and the cold end layer 21 are made of thermally conductive materials such as metal. The cold end layer 21 surrounds the outer periphery of the inner sheath 10, the electrocooling main body layer 22 surrounds the outer periphery of the cold end layer 21, and the hot end layer 23 surrounds the outer periphery of the electrocooling main body layer 22. The multi-core heat dissipation flexible cable 100 also includes an outer sheath 30, which surrounds the outer periphery of the hot end layer 23. The outer sheath 30 is made of an insulating material with a certain thermal conductivity, and it can be thermally coupled to the hot end layer 23 so that the heat generated by the hot end layer 23 can be transferred to the outer sheath 30, and then the heat of the outer sheath 30 and the hot end layer 23 can be removed by means of air blowing.

[0065] It is understood that in other embodiments, the electrocooling body layer 22 may also employ a semiconductor cooling chip. The semiconductor cooling chip is embedded between the hot-end layer 23 and the cold-end layer 21, with its hot end thermally coupled to the hot-end layer 23 and its cold end thermally coupled to the cold-end layer 21. Multiple semiconductor cooling chips are provided, arranged sequentially and at intervals along the extension direction of the flexible cable to improve heat dissipation uniformity.

[0066] It is understood that in this embodiment, the multi-core heat dissipation flexible cable 100 also includes other necessary structures such as an electromagnetic shielding layer and a waterproof layer to realize the cable function, and the specific selection can be made according to actual needs.

[0067] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the scope of this application. All such changes and substitutions fall within the scope defined by this application.
