Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to an intelligent new energy vehicle spare cable with a main cable anomaly detection function. Background Art

[0002] Driven by escalating global environmental and energy pressures and a growing public awareness of environmental protection, the new energy industry is accelerating its rise. As a core driver of the automotive industry's transformation, new energy vehicles (NEVs) fundamentally differ from traditional fuel vehicles in terms of powertrain innovation, intelligent control architecture upgrades, and expanded functionality. Their transmission systems, the lifeblood of energy and signal transmission, urgently require technical solutions compatible with the advancement of vehicle intelligence.

[0003] The technical pain points currently faced by the industry are particularly prominent: traditional cable systems can no longer meet the advanced needs of new energy vehicles. From the perspective of the thermal management system, conventional cables use an outside-to-inside air cooling solution, which violates the temperature gradient law that heat is conducted from the core to the surface. When the heat generated by the conductor exceeds the critical threshold, the heat forms an accumulation effect in the insulation layer. This "hot inside and cold outside" heat dissipation mode not only causes irreversible thermal aging damage, but also buries the hidden danger of overall combustion and explosion. At the structural level, the multi-layer composite design of traditional cables, while improving functional integration, forms a significant heat dissipation barrier, and the simplified structure leads to insufficient functional adaptability, exacerbating the complexity and management difficulty of the vehicle's wiring harness system.

[0004] The intelligent transformation has further exposed the generational gap in traditional cables. The lack of real-time status monitoring and dynamic adjustment mechanisms has rendered cable systems "information islands," requiring only passive responses to faults. Faced with the extreme operating conditions of new energy vehicles, such as the high-frequency charging and discharging and instantaneous high-current surges, existing cables exhibit significant shortcomings in environmental adaptability, including resistance to high-temperature shocks, flame retardancy, and electromagnetic interference resistance. Especially in the high-energy-density component environment within the cabin, transient high temperatures or sparks in adjacent components can easily trigger cascading cable failures. Their safety and reliability are no longer able to meet the stringent transmission component requirements of smart cockpits and autonomous driving systems.

[0005] In summary, the systemic deficiencies of traditional cable systems in high-temperature management paradigms, functional integration architectures, and intelligent sensing capabilities have become key constraints hindering breakthrough performance in new energy vehicles. Developing new intelligent monitoring cables with internal thermal management, state perception, and environmental adaptability has become an inevitable solution to address these industry pain points. Consequently, in-depth research into these issues has led to this case. Summary of the Invention

The dual charging cable redundant system achieves seamless switching via an adjustment component.

This dual-path conductive channel ensures power continuity. The eddy current cooling module utilizes a variable-focus inner diameter adjustment shaft tube, which achieves stepless adjustment from 10 to 80 mm via a rack-and-pinion drive.

A nanocomposite insulating inner sleeve and spiral guide vanes create a Venturi effect, generating spiral low-temperature airflow at a pressure of 0.4 MPa. Combined with an aramid fiber braid, it achieves an IP68 protection rating. The V-shaped wires and leaf spring metal plates in the regulating assembly form an elastic conductive network. In the event of an overload, they automatically shunt current to the resistor metal plate group, reducing transient shocks by over 85% through heat dissipation. Combined with the elastic deformation fixing mechanism of the spring limit lock, this achieves millisecond-level fault isolation. A modular design permeates the entire architecture. The regulating connection box utilizes a plug-in interface to support hot swapping. The eddy current cooler integrates charge-emitting wires to form an electrostatic elimination network, which, in conjunction with the resistor adjuster, achieves dynamic impedance matching. Through mechanical linkage and fluid dynamics optimization, this structure integrates three major functions: fault self-healing, thermal management, and electromagnetic compatibility, while maintaining a 99.2% space utilization rate. This design exemplifies the miniaturization and intelligence of contemporary power equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The present invention will be described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-10As shown, a pair of the charging cables 2 are installed on the charging pile 1 through the adjustment structure, the charging head is installed on the charging cable 2, and the abnormality detection module, the main control module and the abnormality alarm module are installed on the inner side of the charging pile 1, the charging cable 2 and the charging head. The adjustment structure includes: a pair of adjustment connection boxes 101, a pair of shunt cables 102, a pair of cable connectors 103, a rotating connecting rod 104, a rotating connecting shaft 105 and a pair of adjustment components;

[0036] Specifically, a pair of the regulating connection boxes 101 are installed in parallel on the inner side of the charging pile 1, a pair of the regulating components are respectively installed on the inner sides of the pair of regulating connection boxes 101, a pair of the shunt cables 102 are respectively connected to the regulating components in the pair of regulating connection boxes 101, a pair of the shunt cables 102 are connected to the power supply on the charging pile 1, a pair of the cable connectors 103 are respectively installed on the pair of the charging cables 2, a pair of the cable connectors 103 are respectively movably inserted into the regulating components in the pair of regulating connection boxes 101, the rotating connecting rod 104 is inserted into the charging pile 1 through the rotating connecting shaft 105, and the rotating connecting rod 104 is connected to the pair of regulating components;

[0037] It should be noted that, in the above, one of the pair of inflatable cables is made conductive through the adjustment structure, and the other charging cable 2 is kept as a spare, so that when one of the charging cables 2 has a problem, the problematic charging cable 2 is not disconnected in time to avoid damage. At the same time, the electric energy is drained through the adjustment components inside the pair of adjustment connection boxes 101, and the kinetic energy is drained from the inside of the charging pile 1 to the inside of the adjustment components through a pair of shunt cables 102 and a pair of cable connectors 103. When the adjustment component detects a problem, the adjustment component is operated to drive the rotating connecting rod 104 thereon to rotate, so that the rotating connecting rod 104 rotates stably along the rotating connecting axis 105, thereby changing the operating state of the pair of adjustment components.

[0038] like Figure 1-10 As shown, the adjustment assembly includes: a coiled connecting rod 201, a V-shaped connecting wire 202, a limiting shaft tube 203, a pair of limiting rings 204, a convex adsorption metal cylindrical block 205, a buffer spring 206, a pair of concave bearing blocks 207, an I-shaped stretching rod, a flip metal plate 209, a flip limiting shaft 210, a set concave block 211, a pair of arc limiting shafts, a pair of arc set springs 212, a flip connecting cable 213, a quick connecting sleeve 214, a spring limiting lock 215, a leaf spring metal plate 216 and a resistor metal sheet group 217;

[0039] Specifically, the limiting shaft tube 203 is installed on the inner side of the regulating connection box 101, a pair of limiting rings 204 are installed on the inner side of the limiting shaft tube 203, the convex adsorption metal cylindrical block 205 is movably inserted into the inner side of the limiting shaft tube 203, the buffer spring 206 is connected to the convex adsorption metal cylindrical block 205 and the limiting ring 204, the coiled connecting rod 201 is sleeved on the limiting shaft tube 203, the coiled connecting rod 201 is connected to the shunt cable 102, the V-shaped connecting metal rod is connected to the coiled connecting rod 201, a pair of concave bearing blocks 207 are respectively installed on the convex adsorption metal cylindrical block 205 and the rotating connecting rod 104, the I-type stretching rod is connected to a pair of concave bearing blocks 207, and the flip metal plate 209 is turned through the flip The rotation limit shaft 210 is inserted into the inner side of the adjustment connection box 101, the set concave block 211 is set on the flip metal plate 209, a pair of the arc limit shafts are inserted into the inner side of the adjustment connection box 101, and a pair of the arc limit shafts are movably inserted into the set concave block 211, a pair of the arc set springs 212 are respectively set on the pair of arc limit shafts, the quick connection sleeve 214 is inserted into the adjustment connection box 101, the flip connection cable 213 squeezes the quick connection sleeve 214 and the flip metal plate 209, the quick connection sleeve is connected to the cable connector 103, the spring limit lock 215 and the resistor metal sheet group 217 are installed on the inner side of the adjustment connection box 101, and the leaf spring metal plate 216 is connected to the resistor metal sheet group 217 and the flip metal plate;

[0040] It should be noted that, through the precise docking of the shunt cable 102 and the cable connector 103, electrical energy is directed to the coiled connecting rod 201, then conducted via the V-shaped connecting wire 202 to the flip metal plate 209, and finally transmitted to the charging cable 2 connector via the flip connecting cable 213. When the current density of the coiled connecting rod 201 increases abnormally, its electromagnetic effect is significantly enhanced, generating a magnetic attraction force on the convex adsorbent metal cylindrical block 205. This cylindrical block undergoes axial displacement under the guidance of the limiting shaft tube 203, its motion trajectory precisely defined by the limiting ring 204, while the buffer spring 206 provides continuous elastic support to ensure adsorption stability. As the convex adsorbent metal cylindrical block 205 moves, the I-type stretching rod transmits mechanical force via the concave bearing block 207, driving the flip metal plate 209 to angularly displace about the flip limit axis 210. When the flip angle reaches a preset threshold, the spring limit lock 215 triggers the limit mechanism, fixing the metal plate's position through elastic deformation. During this process, the current is synchronously diverted to the leaf spring metal plate 216 and the V-shaped connecting wire 202 to form a dual-path conductive channel, which guides the overloaded electrical energy to the resistor metal plate group 217 for heat dissipation, thereby realizing intelligent protection of the circuit system.

[0041] like Figure 1-10 As shown, the charging pile 1 includes: a set inner box 301, a pair of toothed inflation tubes 302, a pair of cooling air pumps 303, a pair of cable connection plates 304, multiple vortex coolers 305, multiple inner diameter adjustment shaft tubes 306, multiple inner diameter rubber rings, multiple shutters 307, multiple inner diameter gears 308, a pair of inner diameter clamping strips 309, a pair of telescopic shaft tubes 310, a pair of telescopic shaft rods 311 and a pair of lifting electric push rods 312;

[0042] Specifically, the set inner box 301 is installed on the inner side of the charging pile 1, a pair of cable connection plates 304 are respectively connected to the set inner box 301 and the charging pile 1, a plurality of the eddy current cooling tubes are respectively inserted into the charging pile 1, a plurality of the inner diameter adjustment shaft tubes 306 are installed on the plurality of the eddy current coolers 305 and the set inner box 301 through bearings, a plurality of the inner diameter rubber rings are respectively connected to the plurality of the inner diameter adjustment shaft tubes 306 and the eddy current coolers 305, a plurality of the shutters 307 are respectively connected to the plurality of the inner diameter adjustment shaft tubes 306 and the plurality of the eddy current coolers 305, and a plurality of the The inner diameter gears 308 are respectively mounted on the plurality of inner diameter adjustment shaft tubes 306 , a pair of the telescopic shaft tubes 310 are mounted on the inner side of the charging pile 1 , a pair of the telescopic shaft rods 311 are respectively movably inserted into the inner side of the pair of telescopic shaft tubes 310 , a pair of the lifting electric push rods 312 are respectively mounted on the inner side of the pair of telescopic shaft tubes 310 , and the pushing ends of the pair of lifting electric push rods 312 are respectively connected to the pair of telescopic shaft rods 311 , a pair of the inner diameter racks are respectively mounted on the pair of telescopic shaft rods 311 , and a pair of the inner diameter clamping strips 309 are respectively engaged with the plurality of inner diameter gears 308 ;

[0043] It should be noted that, in the above, the electrical appliances inside the charging pile 1 are protected by the suit inner box 301, and the air outside the suit inner box 301 is drained to the toothed air filling tube 302 by the operation of the cooling air pump 303, and the gas is drained to the inner side of multiple vortex coolers 305 by the toothed air filling tube 302, and the gas is quickly cooled by the vortex cooler 305, and the low-temperature air is drained to the inner side of the inner diameter adjustment shaft tube 306, and the shutter device 307 inside the inner diameter adjustment shaft tube 306 is driven to operate, and the lifting electric push rod 312 inside the telescopic shaft tube 310 is extended and retracted, driving the telescopic shaft rod 311 on the pushing end to move along the telescopic shaft tube 310. The inner side of the shaft tube 310 is stably raised and lowered, and the inner diameter clamping strip 309 on it is driven by the telescopic shaft rod 311, so that the inner diameter clamping strip 309 drives multiple inner diameter gears 308 to rotate, and the inner diameter adjustment shaft tube 306 on it is driven to rotate by multiple inner diameter gears 308 respectively. The shape of the inner diameter adjustment shaft tube 306 drives the shutter 307 on the inside of the vortex cooler 305 to rotate, and the rotation of the shutter 307 changes the inner diameter of the inner side of the vortex cooler 305, thereby changing the temperature of the low-temperature air generated by the operation of the equipment, and the inner direction of the suit cooperates with the charging pile 1, so that a pair of cable connection plates 304 drain the electrical energy.

[0044] like Figure 1-10As shown, the charging cable 2 includes: an outer sleeve 401, an inner sleeve 402, a main charging line 403, a threaded rubber ring 404, a plurality of spiral sheets 405, an aramid fiber braided layer 406, an eddy current heat dissipation cooler 407 and an air pump 408;

The inner sleeve 402 and the plurality of spiral blades 405 are made of nanocomposite insulating material, and the outer sleeve 401 is made of a high-temperature resistant silicone layer.

[0046] It should be noted that, in the above, the vortex heat dissipation cooler 407 is inflated by the air pump 408, and the low-temperature gas is drained between the outer sleeve 401 and the inner sleeve 402 by the vortex heat dissipation cooler 407. The air between the outer sleeve 401 and the inner sleeve 402 is spirally drained by the threaded rubber ring 404, so as to quickly cool the inner sleeve 402. Through the cooperation of the low-temperature inner sleeve 402, the main charging line 403 and multiple spiral pieces 405, and the cooperation of the temperature difference and the threaded pieces, a rotating low-temperature airflow is generated in the inner sleeve 402, thereby accelerating the heat absorption effect, and at the same time, the outer side of the inner sleeve 402 is protected by the aramid fiber braided layer 406.

[0047] like Figure 1-10 As shown, the abnormality detection module includes: a temperature sensor, a current and voltage sensor, a capacitance sensor, a partial discharge sensor, an amplification and filtering module, an analog-to-digital conversion unit, and a microcontroller;

[0048] Specifically, the temperature sensor, current and voltage sensor, capacitance sensor, and partial discharge sensor are interconnected in a star topology through a shielded cable, the temperature sensor, current and voltage sensor, capacitance sensor, and partial discharge sensor are connected to the amplification and filtering module, the analog-to-digital conversion unit is connected to the amplification and filtering module, and the microcontroller is connected to the analog-to-digital conversion unit;

In this way, the environment inside the charging cable 2 is monitored, and the environment inside the inner sleeve 402 is monitored in real time.
