[0002] With societal development, the use of electronic products is becoming increasingly frequent, especially with the booming development of smart devices such as drones. However, the usage time of electronic devices is limited by battery power, requiring charging when the battery is low. The availability of charging facilities is also closely related to the number of charging stations. Currently, charging typically uses charging piles, which require consideration of site selection, supporting infrastructure, and other factors. Failure to charge in a timely manner will inevitably affect the use of the equipment. In existing technologies, drones typically need to return to base for charging, significantly impacting their range. Furthermore, the prevalent contact charging method for drones imposes many limitations on drone design, such as restricting the scope for improvement. Therefore, a new wireless charging cable is needed, which allows the device to be charged to be hung on the cable charging unit without being restricted by terrain or other factors, and to achieve the charging function through the electromagnetic induction between the receiving coil of the device and the charging coil.

Detailed Implementation

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0015] like Figure 1 , Figure 2 As shown, a wireless charging cable includes: a first main body 1, a second main body 2, and a third main body 3 integrally formed and sequentially connected, with a specific structure in the shape of an "8". The surface of the second main body 2 is flat, and its thickness is no more than 5 mm. The third main body is larger in size and heavier than the first main body. The first main body 1, the second main body 2, and the third main body 3 are integrally formed from a polymer material; the polymer material is: polyethylene, polyvinyl chloride, rubber, elastomer, low-smoke halogen-free flame-retardant polyolefin, or polyolefin refractory material. The first main body 1 is provided with a first power line 1-1 and a first metal wire clip 1-2. The second main body 2 is provided with a charging unit 2-1, which includes a charging management chip 2-11 and a charging coil 2-13. The charging management chip 2-11 is electrically connected to the charging coil 2-13, that is, the charging management chip 2-11 is electrically connected to the charging coil 2-13 through a chip control line 2-12. The third main body 3 is provided with a second power line 3-1 and a second metal wire clip 3-2. The first power line 1-1 and the second power line 3-1 are electrically connected to the charging management chip 2-11 through the first metal wire clip 1-2 and the second metal wire clip 3-2, respectively. That is, the first power line 1-1 and the second power line 3-1 fix the chip power supply line 2-2 to the charging management chip 2-11 through the first metal wire clip 1-2 and the second metal wire clip 3-2, thereby supplying power to the charging management chip 2-11. The first power cord 1-1, the second power cord 3-1, and the charging unit 2-1 are integrated into the protective housing 4. The protective housing 4 effectively fixes and protects each unit, ensuring that the cable is not damaged during production and use. The protective housing 4 is inside the cable and runs through the first main body 1, the second main body 2, and the third main body 3. In practical applications, there can be multiple charging units 2-1, arranged at certain intervals along the cable direction. The protective housing 4 can be a continuous integral part along the entire cable or it can be set only at the location of the charging unit. The first power cord 1-1 and the second power cord 3-1 are made of tensile-resistant metal wire. The protective housing 4 is made of thermoplastic or thermosetting materials, such as... Figure 3 As shown, the protective housing 4 specifically includes: a power supply cable slot 4-1, a chip power supply cable slot 4-2, a charging management chip slot 4-3, a chip control cable slot 4-4, and a charging coil slot 4-5. In practical applications, the recessed surface of the protective housing is made of a polymer panel that can tightly cover the protective housing, jointly protecting the inserted power cables, chip power supply cables, charging management chip, chip control cable, and charging coil.

[0016] It also includes an identification unit and an antenna. The identification unit is integrated inside the charging management chip 2-11 and uses an identification code identification method. The antenna is integrated on the charging management chip 2-11. The antenna can be connected to the device to be charged in two ways: passive connection and active connection. In passive connection, after receiving the detection signal wave from the device to be charged via the antenna, the charging management chip 2-11 sends a response signal wave. The device to be charged determines the location of the charging management chip 2-11 based on the response signal wave and then charges the device via the charging coil 2-13. In active connection, the charging management chip 2-11 sends an active signal wave via the antenna regardless of whether there is an external detection signal wave. The device to be charged determines the location of the charging management chip 2-11 based on the active signal wave and then charges the device via the charging coil 2-13.

[0017] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
