[0029] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0030] like Figures 1 to 2 As shown, an electric wire and cable for drones in one embodiment of the present invention includes a first cable housing 1, within which a first neutral wire 11 and a first live wire 12 are disposed. The first neutral wire 11 and the first live wire 12 protrude from the end surface of the first cable housing 1. When in use, the first neutral wire 11 and the first live wire 12 are connected to a drone to provide power to the drone. The above is all prior art and will not be elaborated on in detail.

[0031] Since the drone is affected by environmental factors such as airflow and wind speed when hovering in the air, the drone's body will continue to rotate, and torque will be generated between the wires and cables and the drone, causing the connection between the wires and cables and the drone to loosen and be damaged, which will affect the normal use of the drone.

[0032] In order to solve the above problems, Figures 2 to 4 As shown, the drone-use electrical cable also includes a fixed housing 3, integrally formed with a first fixed block 31. A first connecting post 32 and a second connecting post 33 are plugged into the first fixing block 31, extending through both end faces of the first fixing block 31. One end of the first neutral wire 11 is welded to the first connecting post 32, and one end of the first live wire 12 is welded to the second connecting post 33. Specifically, the first neutral wire 11 is electrically conductive to the first connecting post 32, and the first live wire 12 is electrically conductive to the second connecting post 33.

[0033] Further, the protection assembly is rotatably connected on the fixed shell 3, and the protection assembly is rotatable on the fixed shell 3. The second cable sleeve 6 is arranged at one end of the protection assembly away from the fixed shell 3. The second cable sleeve 6 is internally provided with a second zero line 61 and a second live wire 62. The second zero line 61 and the second live wire 62 protrude from the end face of the second cable sleeve 6. The second zero line 61 and the second live wire 62 are fixedly connected to the unmanned aerial vehicle. The second zero line 61 can be in conduction and rotation with the first zero line 11 through the protection assembly. The second live wire 62 can also be in conduction and rotation with the first live wire 12 through the protection assembly.

[0034] Specifically, the protection assembly comprises a rotating shell 4. The rotating shell 4 is integrally formed with a limiting block 41. The fixed shell 3 is provided with a limiting groove 34 matched with the limiting block 41. The limiting block 41 is rotatably connected in the limiting groove 34. The rotating shell 4 is integrally formed with a second fixed block 42. The second fixed block 42 is provided with a first through groove 421 and a second through groove 422. The first through groove 421 is integrally formed with a first conductive block 4211 on the groove wall. The first conductive block 4211 is integrally formed with a fourth connecting column 44 on the upper end face. The second live wire 62 is fixedly connected to the upper end face of the fourth connecting column 44 away from the unmanned aerial vehicle.

[0035] Further, the second connecting column 33 is inserted into the first through groove 421 away from the first fixed block 31. The upper end face of the second connecting column 33 is in close contact with the first conductive block 4211. Specifically, when the rotating shell 4 rotates on the fixed shell 3, the upper end face of the second connecting column 33 is in contact with the lower end face of the first conductive block 4211 for conduction. Meanwhile, the second connecting column 33 can also rotate in the first through groove 421.

[0036] Preferably, the material of the first conductive block 4211 of the second connecting column 33 is graphite. The graphite has excellent conductivity and excellent lubricity.

[0037] Similarly, the second fixed block 42 is provided with an annular groove 423 matched with the second through groove 422. The second through groove 422 is in communication with the annular groove 423. The annular groove 423 is embedded with a second conductive block 4231 on the groove bottom wall. The second conductive block 4231 blocks the second through groove 422 and the annular groove 423. The second conductive block 4231 is integrally formed with a third connecting column 43 on the upper end face. The second zero line 61 is fixedly connected to the upper end face of the third connecting column 43. The first connecting column 32 is inserted into the annular groove 423 away from the first fixed block 31. The first connecting column 32 can rotate in the annular groove 423 and is in close contact with the second conductive block 4231.

[0038] Specifically, the second conductive block 4231 can realize the conduction between the first connecting column 32 and the third connecting column 43. When the rotating shell 4 rotates on the fixed shell 3, the first connecting column 32 rotates in the annular groove 423 while being in conduction with the third connecting column 43. In this way, when the unmanned aerial vehicle hovers and rotates in the air, the first zero line 11 and the second zero line 61 can be in conduction and relative rotation. Similarly, the first live wire 12 and the second live wire 62 can also be in conduction and relative rotation. In this way, it can be ensured that no torque is generated between the power cable and the unmanned aerial vehicle, so that the second zero line 61 and the second live wire 62 can be firmly fixed on the unmanned aerial vehicle. The connection between the unmanned aerial vehicle and the second zero line 61 and the second live wire 62 will not be loose and damaged due to torque, and the power cable can continuously provide power for the unmanned aerial vehicle and the lighting system, so that the unmanned aerial vehicle can continuously illuminate and ensure the continuous progress of the rescue work.

[0039] It is worth noting that long-term use will inevitably cause wear between the first connecting column 32 and the first conductive block 4211, and between the second connecting column 33 and the second conductive block 4231. When wear occurs, the positions of the first connecting column 32 and the second connecting column 33 on the first fixed block 31 can be adjusted, so that the first connecting column 32 and the second connecting column 33 are reattached to the first conductive block 4211 and the second conductive block 4231. In this way, the service life can be prolonged.

[0040] Further, when the first connecting column 32, the second connecting column 33, the first conductive block 4211 and the second conductive block 4231 need to be replaced due to excessive wear, as shown in Figures 3 to 5 The first connecting column 32, the second connecting column 33, the third connecting column 43 and the fourth connecting column 44 are all provided with threaded holes, and the first connecting column 32, the second connecting column 33, the third connecting column 43 and the fourth connecting column 44 are all threadedly connected with bolts 7. The first zero line 11, the first live wire 12, the second zero line 61 and the second live wire 62 are all fixedly connected with wire noses 8 matched with the bolts 7.

[0041] Specifically, the first zero line 11 and the first connecting column 32 can be detachably connected through the bolts 7 and the wire noses 8. Similarly, the first live wire 12 and the second connecting column 33, the second zero line 61 and the third connecting column 43, and the second live wire 62 and the fourth connecting column 44 can also be detachably connected. In this way, when the first connecting column 32, the second connecting column 33, the first conductive block 4211 and the second conductive block 4231 need to be replaced due to excessive wear, the first zero line 11, the first live wire 12, the second zero line 61 and the second live wire 62 can be respectively detached, and the fixed shell 3 and the rotating shell 4 can be replaced as a whole.

[0042] Further, the first cable sleeve 1 is attached with a first connecting shell 2, and the end of the first connecting shell 2 away from the first cable sleeve 1 is attached to the fixed shell 3. The second cable sleeve 6 is attached with a second connecting shell 5, and the end of the second connecting shell 5 away from the second cable sleeve 6 is attached to the rotating shell 4. The first connecting shell 2 and the second connecting shell 5 are elastic connecting shells. Specifically, the first connecting shell 2 and the second connecting shell 5 can protect the first zero line 11, the first fire line 12, the second zero line 61 and the second fire line 62 exposed outside. When the bolt 7 is disassembled, the first connecting shell 2 and the second connecting shell 5 can be turned over, so that the fixed shell 3 and the rotating shell 4 are exposed.

[0043] In use, when the unmanned aerial vehicle rotates in the air, the rotating shell 4 can rotate on the fixed shell 3, the second connecting column 33 rotates in the first through groove 421, and the first connecting column 32 also rotates in the annular groove 423, so that the power transmission between the wire cable and the unmanned aerial vehicle is realized, and the torque between the wire cable and the unmanned aerial vehicle is prevented.

[0044] Compared with the prior art, the wire cable for the unmanned aerial vehicle can rotate itself when twisted, effectively avoiding the phenomenon that the connection between the wire cable and the unmanned aerial vehicle is loose and damaged due to twisting, thereby significantly improving the operation ability of the unmanned aerial vehicle in a complex environment and providing reliable protection for rescue work.
