[0002] With the development of the field of unmanned aerial vehicles, unmanned aerial vehicle clusters and the collaborative work of unmanned aerial vehicles and various carriers have gradually become a new development trend and are increasingly used in daily production and life. This is specifically reflected in three aspects: material transportation (used for the transfer of goods or materials between unmanned aerial vehicles, which can be used in the fields of emergency rescue, disaster areas or supply chains, etc.), charging and energy supply (which can be used to realize the power transmission or energy supply of unmanned aerial vehicles and prolong the endurance time of unmanned aerial vehicles), data exchange and transmission (which can realize the exchange and transmission of data and improve the effectiveness of collaborative work, cooperative tasks and information sharing).
[0003] As of now, the existing unmanned aerial vehicle docking technologies at home and abroad mainly include magnetic docking, mechanical arm docking, fly hook docking and infrared guided docking. Among them, the magnetic docking has the advantages of simplicity and speed, but the docking stability and carrying capacity are poor. The mechanical arm docking realizes the docking of unmanned aerial vehicles by using a mechanical arm, which has high accuracy and stability, but the docking process is relatively complex and requires high autonomous flight control technology. The fly hook docking realizes the docking between unmanned aerial vehicles through a fly hook or similar mechanism, which has good stability and carrying capacity, but the docking process requires high precision control and coordination. Finally, the infrared guided docking realizes the docking of unmanned aerial vehicles by using infrared sensors, which has high autonomy and flexibility, but is affected by environmental conditions and sensor accuracy. SUMMARY

The multi-rotor vehicle can complete magnetic docking with the magnet on the multi-rotor vehicle under the action of the electromagnet within a certain range from the docking platform, the multi-rotor vehicle switches to a self-defined anti-torque mode to complete the locking after the docking by clamping the arm into the clamp, and the power transmission can be performed after the locking, thereby improving the endurance of the vehicle when performing a task alone.

[0006] The Pogo Pin probe is a spring probe formed by three basic components of a needle shaft, a spring and a needle tube through precise instrument riveting and pre-pressing, and has a precise spring structure inside.
[0007] Further improvement, the plurality of clamps have clamp openings opened in the same direction on the circumference, and the arms of the multi-rotor structure are clamped and fixed by the clamps. The Pogo Pin probes are arranged inside the clamp openings, and the clamps lock the Pogo Pin probes and the conductive structure when the arms are clamped into the clamp openings.
