[0002] In recent years, the rapid development of unmanned aerial vehicle (UAV) technology has provided a technical basis for the emergence of automatic airports. UAVs, as a general term for unmanned aircraft, have the advantages of small size, low cost, convenient use, low requirements for the operating environment, and strong battlefield survivability. With the progress of technology, UAVs have been widely used in many fields such as aviation, military, agriculture, and construction. Especially in fields such as aerial photography, agricultural plant protection, express delivery, disaster relief, and environmental monitoring, UAVs have demonstrated great application potential. The continuous growth of industry demand has promoted the development of UAV automatic airports. With the wide application of UAVs in various industries, the demand for infrastructure such as UAV takeoff and landing, charging, and data transmission has also increased day by day.

[0003] Traditional UAV takeoff and landing methods are often limited by factors such as site conditions and personnel operation, while UAV automatic airports can provide a more convenient and efficient solution. Through automated and intelligent technical means, UAV automatic airports can achieve functions such as automatic takeoff and landing, charging, and data transmission of UAVs, greatly improving the use efficiency and safety of UAVs. UAV automatic airports not only provide a protected place for UAVs against harsh weather conditions, theft, and wild animals, but also can realize functions such as automatic scheduling and task allocation of UAVs through an intelligent management system. This can not only reduce personnel operation costs, improve the working efficiency of UAVs, but also further enhance the application level of UAVs in various industries. However, when the existing UAV airports are automatically charging, there may be a situation where charging cannot be carried out due to accidental disconnection of the charging connector, which will cause the automatic system to interrupt, lose stability, and cause unnecessary problems.

[0004] Chinese patent document CN114784924A discloses a charging device for an unmanned aerial vehicle (UAV), comprising a charging device base, a charging device column, a charging device shed, a charging device connecting rod, and a charging device block. The bottom of the charging device column is connected to the charging device base, the top of the charging device column is connected to the charging device shed, the top of the charging device connecting rod is connected to the charging device shed, and the bottom of the charging device connecting rod is connected to the charging device block. The charging device connecting rod is a rigid connecting rod with a hollow structure. A charging cable and a charging head are installed inside the charging device connecting rod. A clamping device is also installed on the charging head. An electromagnet is installed on the charging head. The bottom of the charging cable is electrically connected to the charging head. A power supply is installed on the charging device base, and the power supply is electrically connected to the charging cable and the electromagnet, respectively. A UAV charging head is installed on the UAV, and the UAV charging head and the charging device charging head dock to complete charging of the UAV. However, existing UAV airports may experience charging failures due to accidental disconnection of the charging connector during automatic charging, which can interrupt the automatic system, lose stability, and cause unnecessary problems.

[0005] In view of this, the utility model provides a magnetic docking charging device with a re-attraction function. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the utility model provides a magnetic docking charging device with a re-attraction function to solve the problem that the existing drone airport may fail to charge during automatic charging, resulting in interruption of the automatic system, loss of stability, and unnecessary situations.

[0007] The detailed technical solution of this utility model is as follows:

[0008] A magnetic docking charging device with a re-attraction function includes a charging adapter, which is installed on the apron of an automatic airport for unmanned aerial vehicles. A magnetic docking connector is installed on the upper part of the charging adapter, the upper part of a connecting PCB board is connected to the back of the magnetic docking connector, and the lower part of the connecting PCB board is connected to a wiring harness.

[0009] Preferably, the charging adapter is mounted on the magnetic docking connector and connected to the PCB board via a first bolt.

[0010] Preferably, a copper pin extends from the back of the magnetic docking connector, and the upper portion of the connecting PCB board is welded in the middle of the copper pin extending from the magnetic docking connector.

[0011] Preferably, a welding disk is provided at the lower portion of the connecting PCB board, and the wiring harness and the connecting PCB board are welded together through the welding disk.

[0012] Preferably, there are two oblong holes, one above the other, in the middle of the connecting PCB board.

The dial pin passes through the lower oblong hole and is installed on the electromagnet.

[0013] Preferably, the upper part of the electromagnet is installed with a dial pin and fastened to the charging adapter through the second bolt.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] (1) In the present utility model, when the drone lands in the automatic airport for automatic charging, if there is a problem that the magnetic adsorption docking head cannot be charged due to landing deviation after docking, the electromagnet can be energized to act, pulling down the connecting PCB and the magnetic adsorption docking head together by a certain distance, and then quickly cutting off the power. Because of the magnetic force, the magnetic adsorption docking head is pulled up and re-sucked together. Since there is no other structural limitation, only the suction effect of the magnetic force on both sides, the magnetic adsorption docking head can be accurately sucked together, achieving the effect of accurate connection after re-suction and realizing the purpose of automatic charging of the drone.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] As Figure 1 and Figure 2 shown, a magnetic docking charging device with a re - suction function includes a charging adapter 3. The charging adapter 3 is installed on the apron 1 of the unmanned aerial vehicle (UAV) automatic airport. A magnetic docking head 2 is installed on the upper part of the charging adapter 3. The upper part of a connecting PCB board 4 is connected to the back of the magnetic docking head 2, and the lower part of the connecting PCB board 4 is connected to a wire harness 10 together.

[0023] The charging adapter 3 installs the magnetic docking head 2 and the connecting PCB board 4 through a first bolt 6.

[0024] Copper pins 12 protrude from the back of the magnetic docking head 2, and the upper part of the connecting PCB board 4 is welded in the middle of the copper pins 12 protruding from the magnetic docking head 2.

[0025] Welding pads 13 are provided at the lower part of the connecting PCB board 4, and the wire harness 10 and the connecting PCB board 4 are welded together through the welding pads 13.

[0026] There are two upper and lower oblong holes in the middle of the connecting PCB board 4. The first bolt 6 connects the welded connecting PCB board 4 to the charging adapter 3 through the upper oblong hole. A dial pin 8 passes through the lower oblong hole, and the dial pin 8 is installed on an electromagnet 9.

[0027] The upper part of the electromagnet 9 installs the dial pin 8 and is fastened to the charging adapter 3 through a second bolt 11.

[0028] Embodiment 2,

[0029] For a magnetic docking charging device with a re - suction function as described in Embodiment 1, a charging adapter 3 is installed on the apron 1 of the UAV automatic airport. The pins protruding from the magnetic docking head 2 are welded to the pads on the connecting PCB board 4. The wire harness 10 is welded to the pad area at the lower part of the connecting PCB board 4. The welded magnetic docking head 2, connecting PCB board 4 and wire harness 10 are passed through the charging connector 3 from top to bottom. The first bolt 6 passes through the charging connector and the connecting PCB board 4, and then passes through the charging adapter 3. The first bolt 6 passing through the charging adapter 3 is screwed with a first locknut 5 and tightened. The dial pin 8 passes through the electromagnet 9 and is screwed with a second locknut 7 and tightened. The assembled electromagnet 9 is assembled to the charging adapter 3 with the second bolt 11, and at the same time, the dial pin 8 passes through the charging adapter 3 and the connecting PCB board 4. When the magnetic docking head 2 is not sucked in place, it will cause the circuit on the PCB not to detect the suction signal. The system will control the electromagnet 9 to drive the dial pin 8 to pull down the connecting PCB board 4, and then quickly cut off the power. The electromagnet 9 loses its pulling force, and the magnetic docking head 2 relies on the magnetic suction force to accurately suck up, realizing the re - suction function.
