However, due to the limitation of drone battery capacity, the endurance of drones is severely restricted, so the intelligent energy supply of drones is an urgent problem to be solved.

[0003] Wireless power transmission (WPT) technology is a new type of power transmission technology that uses electromagnetic waves or mechanical waves to transmit power from power source to load without electrical contact. Since there is no physical connection between the power source and the load during the transmission process of WPT technology, compared with the traditional contact transmission method, WPT technology can avoid various hidden dangers caused by hardware connection and greatly improve the flexibility of electrical equipment. Therefore, wireless power transmission (WPT) technology has become a hot research direction in the field of drone charging.

[0004] After a drone is used, the temperature of the battery inside the drone shell and the circuit components inside the drone is high. There will also be heat loss during the charging process of the drone, low charging efficiency of the guide column, or easy damage to the equipment. In response to the above technical problems, existing studies have mostly adopted the method of adding fan equipment to the drone hangar to cool the drone.

[0043] As for the parking platform unit 100, it is divided into two parts, including a shell assembly 101 and a pipe assembly 102 arranged in the shell assembly 101; further, the shell assembly 101 includes a platform bottom shell 101a and a mounting frame 101b arranged on the top surface of the platform bottom shell 101a; the pipe assembly 102 is arranged on the platform bottom shell 101a through the mounting frame 101b, and includes a middle support member 102a, a plurality of evenly distributed air guide tubes 102b, and a pipe assembly 102c connected between the middle support member 102a and the air guide tube 102b.

[0044] Specifically, the platform bottom shell 101a is hollow inside, and the side wall of the top shell is provided with a middle through hole 101a-1 and a pipe hole 101a-2, and the number of the pipe holes 101a-2 is the same as the number of the air guide tube 102b. The middle through hole 101a-1 and the pipe hole 101a-2 are both used for the installation of the pipe assembly 102c.

[0045] The mounting frame 101b includes a plurality of supporting legs 101b-1 and a connecting frame 101b-2 connected to the upper end of each supporting leg 101b-1, and a plurality of limiting ring grooves 101b-3 are provided in the connecting frame 101b-2. The supporting legs 101b-1 support the connecting frame 101b-2 and lift it off the top surface of the platform bottom shell 101a; it should be noted that the limiting ring grooves 101b-3 are used for the installation of the air guide tube 102b; and the limiting ring grooves 101b-3 correspond to the positions and numbers of the pipe holes 101a-2.

[0046] Furthermore, the middle support member 102a includes an intermediate conduit 102a-1, an outer conduit 102a-2 sleeved on the outer side wall of the intermediate conduit 102a-1, and a buffer spring 102a-3 disposed between the intermediate conduit 102a-1 and the outer conduit 102a-2; the intermediate conduit 102a-1 is divided into a large tube D and a small tube X, the lower end of the small tube X passes through the middle through hole 101a-1 and extends inside the shell of the platform bottom shell 101; the buffer spring 102a-3 is sleeved on the small tube 201a-2, one end of which is connected to the side wall of the large tube D, and the other end is connected to the inner cavity side wall of the outer conduit 102a-2; the outer conduit 102a-2 is longer than the axial length of the large tube D, and a buffer washer H is disposed at its tube mouth. And the first heat dissipation port 301a can correspond to the position of the middle support member 102a.

[0047] The middle support member 102a is installed by penetrating the middle through hole 101a-1, and is located in the middle of the platform bottom shell 101a, facing the middle position of the bottom of the parked UAV, and is used to support the body of the parked UAV. The outer conduit 102a-2 with the buffer gasket H can first make soft contact with the body of the UAV during the parking process of the UAV, and under the action of the buffer spring 102a-3, after the UAV stops, the outer conduit 102a-2 can contact the side wall of the bottom of the UAV, and face the first heat dissipation port 301a at the bottom, to help the body dissipate heat. It should be noted that the elastic force of the buffer spring 102a-3 is less than the gravity of the UAV.

[0048] The air guide tube 102b is funnel-shaped, with a large open top, and is installed correspondingly in the limiting ring groove 101b-3. The top is open to facilitate the insertion of the drone rotor 302a, and the bottom is small, which is connected to the branch pipe 102c-3 in the pipeline assembly 102c. Through the rotation of the rotor 302a, negative pressure is generated to dissipate heat and cool the drone body.

[0049] Furthermore, a boss 102b-1 is provided on the outer wall of the air guide tube 102b, a positioning notch 102b-2 is provided in the boss 102b-1, the positioning notch 102b-2 penetrates the side wall of the air guide tube 102b, and a guiding bevel 102b-3 is provided at the opening edge of the positioning notch 102b-2; the number of air guide tubes 102b is the same as the number of rotors 302a of the drone. The positioning notch 102b-2 is provided for the placement of the wings 302 of the drone, and has the function of positioning and resisting deviation; and the guiding bevels 102b-3 on both sides of the edge are used to improve the guidance of the drone during landing, thereby improving the tolerance during landing.

[0050] The wing 302 and the rotor 302a can be placed in the positioning notch 102b-2 and the air guide tube 102b accordingly.

[0051] The boss 102b-1 is located on the outer side wall of the air guide tube 102b and protrudes from the side wall, all facing the corresponding wing 302 position of the drone. The boss 102b-1 is circular in axial direction, and a limited slide groove 102b-11 is provided on the outer side wall thereof, and a rotating ring 102b-12 is rotatably provided in the limited slide groove 102b-11, and a notch Q having an arc not less than the positioning notch 102b-2 is provided on the rotating ring 102b-12, and the rotating ring 102b-12 can cover the positioning notch 102b-2. It is used to lock the wing 302 of the drone after parking, thereby improving the safety and stability of the drone parking. The rotating ring 102b-12 will not fall off when rotating in the limiting slide groove 102b-11. When its notch Q coincides with the positioning notch 102b-2, it will not affect the placement of the wing 302 into the positioning notch 102b-2. After the wing 302 is placed in, the rotating ring 102b-12 is rotated to make the notch Q and the positioning notch 102b-2 misaligned, thereby achieving the locking of the wing 302 by the rotating ring 102b-12; at the same time, it will cooperate with the buffer spring 102a-3 to support the external guide tube 102a-2, thereby forming a clamping force to limit the body 301 of the drone.

[0053] Under the action of the pipeline component 102c, the wind force generated by the drone rotor 302a can be guided to the middle part of the fuselage 301 through the pipeline; when the rotor 302a rotates at a low speed, the energy consumption is low and the drone will not take off, but the heat exchange between the fuselage 301 and the outside world can be greatly improved to achieve rapid heat dissipation; when the rotor 302a rotates at a high speed, the high-speed airflow generated by the rotor 302a is guided to the bottom of the fuselage 301, which will push the drone to take off more easily and leave the parking position.

[0063] S2: Charging starts, the temperature sensor module collects temperature data of the power receiving end 202 and the internal load of the drone in real time. If the monitored temperature is greater than or equal to the preset temperature value, the process goes to step S3.
