When the current increases, the chemical reaction inside the battery cell will produce more gas, causing the internal pressure to increase, affecting the overall service life of the cable. Therefore, it is necessary to propose a cable for new energy electric vehicles. Summary of the invention

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the present invention, when the temperature of the cable rises due to the passage of current, the heat is transferred to the high-efficiency heat-conducting rod through the contact guide rod head, and the continued heat of the cable operation is conducted to the memory metal block through the high-efficiency heat-conducting rod, so that the memory metal block is deformed by heat and its volume increases. As its volume changes, a downward extrusion force is formed on the contact end, so that the contact end drives the first engaging member to rotate in the rotating frame under the action of the stress spring, so that the engaging state of the first engaging member and the second engaging member changes, so that the second engaging member rotates under the action of the rotating link and the rotating structure, driving the trigger lever on the end surface to move downward, and the trigger lever pushes the sliding superconductor to slide downward, so that it penetrates the inner shielding layer and forms an active contact with the twisted outer core. Dynamic contact. Since the sliding superconductor has superconducting properties, it can significantly increase the current carrying capacity after contacting the twisted outer core to meet high current requirements. When the current decreases or the temperature returns to normal, the elastic tension wire pulls the sliding superconductor back to its original position under its own elastic action. After returning to its original position, the bottom end of the sliding superconductor creates a contact space with the outer surface of the twisted outer core, while still penetrating and sliding with the inner shielding layer to ensure that the operation of the inner shielding layer is not affected by the sliding operation of the sliding superconductor. It then returns to its initial state and prepares for the next adjustment. The overall effect is to achieve efficient conductivity, reduce resistance, and increase current carrying capacity, thereby improving the conductivity of the cable and reducing energy loss. It can meet the high requirements of new energy electric vehicles for cables and improve the overall performance and safety of electric vehicle cables.

[0023] 2. In the present invention, when the air pressure rises due to the heat generated by the passage of electric current inside the cable under the cooperation of the dynamic adjustment component, the bottom of the floating air float is connected to the floating air plate, and the floating air plate forms a high and low staggered structure, which will produce different degrees of buoyancy changes when the air pressure changes. As the air pressure increases, the buoyancy increases, driving the floating air float to move upward, and because the sliding edge is tightly slidably connected to the inner wall of the airflow dissipation chamber, the stability and directionality of the movement of the floating air float are ensured. When the floating air float moves upward, the connecting rod drives the connecting section rod and the connecting force section rod to move synchronously, thereby making the inner sliding connection block form a synchronous inward sliding on the sliding column, and then the sliding airflow plate at the side end of the inner sliding connection block synchronously slides in the pressure dissipation chamber toward the central end of the airflow dissipation chamber, and begins to change the airflow channel structure and airflow resistance in the pressure dissipation chamber. As the sliding airflow plate slides, the pressure dissipation chamber and the exhaust chamber are connected. The connectivity between the channels is gradually adjusted, so that the pressurized gas in the airflow dissipation cavity can flow into the exhaust cavity and dissipate more smoothly through the pressure dissipation cavity. In this process, the high and low staggered floating air plates not only play the role of transmitting buoyancy, but also produce a turbulence effect in the gas flow process, promote gas mixing and heat dissipation, and accelerate the heat inside the cable to be dissipated with the airflow, thereby reducing the internal temperature of the cable and achieving pressure balance. When the internal pressure of the cable gradually returns to normal, the buoyancy of the floating air float decreases, and it begins to fall downward under the action of gravity, driving the entire linkage structure to move in the opposite direction, sliding the airflow plate back to its position, and restoring the initial airflow channel state of the pressure dissipation cavity, so that when the current increases, the internal pressure is dynamically reduced, thereby increasing the service life of the cable, realizing automatic adjustment of the internal pressure and temperature of the cable and efficient heat dissipation, and ensuring the safe and stable operation of cables for new energy electric vehicles.

[0024] 3. In the present invention, the support bars and the filling microcapsule layer are coordinated to insert the support bars into the filling microcapsule layer, so as to provide structural support for the entire inner protective layer, maintain its shape and stability, and prevent the inner protective layer from excessive deformation or damage under mechanical stress such as cable bending and stretching. When the inner protective layer is damaged due to long-term excessive bending, the microcapsules in the filling microcapsule layer can rupture and release self-healing agents to fill the cracks and restore the insulation performance. At the same time, when the cable encounters a fire or a local high temperature environment, the flame retardant capsules in the protective cavity will rupture due to the high temperature and release the flame retardant. The flame retardant can quickly form an isolation layer around the cable to prevent the spread of flames, reduce the speed and intensity of cable burning, buy time for personnel evacuation and fire extinguishing, and reduce the generation of toxic gases and the harm of fire to personnel and equipment.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Reference Figure 1-Figure 6 Shown: A cable for new energy electric vehicles, including:

[0034] The flow cavity 3 is equally spaced and installed outside the cable wear-resistant protective sleeve 1, and is used to allow the gas to escape from the exhaust cavity 4 opened around the side surface when the pressurized gas is generated inside;

[0035] The current detection sensor is equally installed inside the inner protective layer 7, and is used to cooperate with the temperature detection sensor 18 to detect the current value and temperature value generated by the cable in real time, and feed it back to the built-in microprocessor of the cable wear-resistant protective cover 1 for analysis;

[0036] Dynamic adjustment components 16, which form multiple groups and are arranged around the inside of the circulation cavity 3, are used to actively form pressure relief and ventilation and temperature reduction operations when pressurized gas is generated;

[0037] The current carrying capacity dynamic adaptive adjustment component 15 is arranged in multiple groups and is installed inside the outer shell end 2, and is used to form an adaptive adjustment operation for the internal conductor according to the temperature change caused by the current size;

[0038] The twisted outer core 9 is installed inside the inner shielding layer 8 and forms a twisted gap 19. Nanosilver particles are filled in the twisted gap 19 so that the nanosilver particles and the twisted outer core 9 form a composite setting in the manufacturing process, which is used to form a conductor setting with the inner core 13.

[0039] In the present invention, according to Figure 3 and Figure 4 As shown, the current carrying capacity dynamic adaptive adjustment component 15 includes:

[0040] The memory metal block 150, the contact end 151, the first engaging member 152 and the rotating frame 153. The side end of the memory metal block 150 is connected with a high-efficiency heat-conducting rod 17. The high-efficiency heat-conducting rod 17 forms contact with the inner shielding layer 8 through multiple groups of contact rod heads in turn. A stress spring is installed at the bottom of the first engaging member 152. The first engaging member 152 is located inside the rotating frame 153 through the stress spring to form rotation adjustment.

[0041] A hook 159 is integrally formed at the side end of the rotating frame 153, and the front end of the first engaging member 152 is engaged with the second engaging member 154. The second engaging member 154 contacts the hook 159 after operation, and a rotating link 155 is integrally formed at the side end of the second engaging member 154. A rotating structure 157 is installed inside the rotating link 155.

[0042] The side end of the rotating link 155 is integrally formed with an end face 156, and a trigger lever 158 is fastened to the surface of the end face 156. A sliding superconductor is installed at the bottom of the trigger lever 158, and the sliding superconductor slides through the inner shielding layer 8 and the twisted outer core 9 to form a movable contact setting.

[0043] An elastic tension wire 1590 is provided at the side end of the sliding superconductor, and the side end of the elastic tension wire 1590 is fastened to the inner wall surface of the outer shell end 2. The elastic tension wire 1590 is used to drive the sliding superconductor to return to its original position under the action of elastic tension after the sliding superconductor slides downward and contacts the twisted outer core 9 due to the force applied by the trigger rod 158 to increase the current carrying capacity, so that a contact space is generated with the outer surface of the twisted outer core 9, and the bottom end of the sliding superconductor after returning to its original position synchronously penetrates the inner shielding layer 8 and slides.

[0044] In a specific solution, when current passes through the cable, the current first flows through the conductor composed of the twisted outer core 9 and the inner core 13. The nano silver particles in the twisted outer core 9 can improve the overall conductivity of the conductor and reduce resistance loss due to their good conductivity. At the same time, the current detection sensor inside the inner protective layer 7 monitors the current value in real time, and the temperature detection sensor 18 monitors the temperature value of the cable in real time, and feeds back these data to the built-in microprocessor of the cable wear-resistant protective cover 1, so that when the temperature of the cable rises due to the passage of current, the heat is transferred to the high-efficiency heat-conducting rod 17 through the contact guide rod head, and then the continued heat of the cable operation is conducted to the memory metal block 150 through the high-efficiency heat-conducting rod 17, so that the memory metal block 150 is deformed by heat and increases in volume. As its volume changes, a downward squeezing force is formed on the contact end 151, so that the contact end 151 drives the first engaging member 152 to rotate in the rotating frame 153 under the action of the stress spring, so that the engaging state of the first engaging member 152 and the second engaging member 154 changes, so that the second engaging member 154 is connected to the memory metal block 150. The coupling 154 rotates under the action of the rotating link 155 and the rotating structure 157, driving the trigger lever 158 on the end face 156 to move downward, and the trigger lever 158 pushes the sliding superconductor to slide downward, so that it penetrates the inner shielding layer 8 and forms active contact with the twisted outer core 9. Since the sliding superconductor has superconducting properties, it can significantly increase the current carrying capacity after contacting the twisted outer core 9 to meet the high current demand. When the current decreases or the temperature returns to normal, the elastic tension wire 1590 pulls the sliding superconductor back to its original position under the action of its own elasticity. After returning, the bottom end of the sliding superconductor creates a contact space with the outer surface of the twisted outer core 9, while still penetrating and sliding with the inner shielding layer 8 to ensure that the operation of the inner shielding layer 8 is not affected by the sliding operation of the sliding superconductor. It then returns to its initial state to prepare for the next adjustment. The overall efficient conduction is effectively achieved, the resistance is reduced, and the current carrying capacity is increased, thereby improving the conductive performance of the cable and reducing energy loss. It can meet the high requirements of new energy electric vehicles for cables and improve the overall performance and safety of electric vehicle cables.

[0045] In the present invention, according to Figure 3 and Figure 5 As shown, the dynamic adjustment component 16 includes:

[0046] The airflow dispersing cavity 160, the sliding edge 161, the floating air float 162 and the floating air plate 163, the pressure dispersing cavity 165 is passed through the left and right ends of the top of the airflow dispersing cavity 160, the pressure dispersing cavity 165 and the exhaust cavity 4 are connected, the sliding edge 161 is located on the inner wall surface of the airflow dispersing cavity 160 and is slidably connected, the sliding edge 161 and the outer surface of the floating air float 162 are tightly connected, the floating air plate 163 forms a high and low staggered distance difference, and is tightly connected to the bottom of the floating air float 162.

[0047] The top of the floating air float 162 is fastened with a connecting rod 164, and the two ends of the top of the connecting rod 164 are symmetrically connected with connecting section rods 166. The top of the connecting section rod 166 is connected with a connecting force section rod 167, and the top of the connecting force section rod 167 is installed with an inner sliding connecting block 168.

[0048] The inner sliding connection block 168 is internally slidingly connected with a sliding column 169, and the top of the central end of the sliding column 169 is fastened to the top of the airflow distribution chamber 160 through a connecting column. The side end of the inner sliding connection block 168 is fastened to a sliding airflow plate 1690, and the sliding airflow plate 1690 is located in the internal sliding connection of the pressure dissipation chamber 165.

[0049] In a specific solution, when the air pressure rises due to the heat generated by the passage of electric current inside the cable, the gas pressure in the air flow dispersing chamber 160 will change. The bottom of the floating air float 162 is connected to the floating air plate 163, and the floating air plate 163 forms a high and low staggered structure, which will produce different degrees of buoyancy changes when the air pressure changes. As the air pressure increases, the buoyancy increases, driving the floating air float 162 to move upward. Since the sliding edge 161 is tightly slidably connected to the inner wall of the air flow dispersing chamber 160, the stability and directionality of the movement of the floating air float 162 are ensured. When the floating air float 162 moves upward, the connecting rod 164 drives the connecting section rod 166 and the connecting force section rod 167 to move synchronously, thereby causing the inner sliding connection block 168 to form a synchronous inward sliding on the sliding column 169, and then the sliding air flow plate 1690 at the side end of the inner sliding connection block 168 synchronously slides toward the central end of the air flow dispersing chamber 160 in the pressure dispersing chamber 165, and begins to change the air flow channel structure and air flow resistance in the pressure dispersing chamber 165. As the sliding airflow plate 1690 slides, the connection state between the pressure dissipation chamber 165 and the exhaust cavity 4 is gradually adjusted, so that the pressurized gas in the airflow dissipation chamber 160 can flow into the exhaust cavity 4 and be dispersed more smoothly through the pressure dissipation chamber 165. In this process, the high and low staggered floating air plates 163 not only play the role of transmitting buoyancy, but also produce a turbulent effect in the process of gas flow, promote gas mixing and heat dissipation, accelerate the heat inside the cable to be dissipated with the airflow, thereby reducing the internal temperature of the cable and achieving pressure balance. When the internal pressure of the cable gradually returns to normal, the buoyancy of the floating air float 162 is reduced, and it begins to fall downward under the action of gravity, driving the entire linkage structure to move in the opposite direction, and the sliding airflow plate 1690 returns to its original position, restoring the initial airflow channel state of the pressure dissipation chamber 165, so that when the current increases, the internal pressure is dynamically reduced as a whole, thereby increasing the service life of the cable, realizing automatic adjustment of the internal pressure and temperature of the cable and efficient heat dissipation, and ensuring the safe and stable operation of cables for new energy electric vehicles.

[0050] In the present invention, according to Figure 1 , Figure 2 and Figure 6 As shown, an insulating layer 12 is arranged inside the inner protective layer 7, a metal mesh 14 is arranged outside the inner shielding layer 8, a filling microcapsule layer 11 is installed inside the insulating layer 12, and a supporting column 10 is inserted inside the filling microcapsule layer 11.

[0051] The side end of the circulation cavity 3 is fastened with a connecting bending area 5, the inner wall of the cable wear-resistant protective sleeve 1 is installed with an anti-corrosion layer 6, and a plurality of groups of protective cavity bubbles 20 are installed inside the inner protective layer 7, and the interior of the plurality of groups of protective cavity bubbles 20 is filled with flame retardant capsules 21.

[0052] In a specific scheme, when the current is transmitted in the twisted outer core 9 and the inner core 13, the insulating layer 12 first forms an isolation current and prevents leakage, ensuring that the electric energy is only conducted in an orderly manner inside the conductor to avoid electrical hazards to the outside (the insulating layer 12 is made of cross-linked polyethylene material). The metal wire mesh 14 and the inner shielding layer 8 are set to shield external electromagnetic interference, prevent the external electromagnetic field from affecting the current signal transmitted inside the cable, ensure the stability and accuracy of the signal, and also reduce the interference of the electromagnetic field generated by the internal current of the cable to the outside world. Then the support bar 10 is inserted into the filling microcapsule layer 11 to provide structural support for the entire inner protective layer 7, maintain its shape and stability, and prevent the inner protective layer 7 from excessive deformation or damage under mechanical stress such as cable bending and stretching. The microcapsules in the filling microcapsule layer 11 can be broken and released when the inner protective layer 7 is damaged due to excessive bending for a long time. The self-healing agent is released to fill the cracks and restore the insulation performance (the inner protective layer 7 is made of polyimide material), and the setting of the connecting bending area 5 is convenient for the use of the cable as a whole and increases the bending adjustment performance. Then the anti-corrosion layer 6 on the inner wall of the cable wear-resistant protective sleeve 1 can prevent external corrosive substances such as moisture, acid and alkali solutions from corroding the metal parts and insulating materials inside the cable, extending the service life of the cable and ensuring that it can work normally in various harsh environments (the anti-corrosion layer 6 is made of polyvinyl chloride and fluoroplastic composite materials). Then, when the cable encounters a fire or a local high temperature environment, the flame retardant capsule 21 in the protective cavity 20 will rupture due to the high temperature and release the flame retardant. The flame retardant can quickly form an isolation layer around the cable to prevent the spread of flames, reduce the speed and intensity of cable burning, and buy time for personnel evacuation and fire extinguishing. At the same time, it reduces the generation of toxic gases and reduces the harm of fire to personnel and equipment.
