[0002] In recent years, drones have played an important role in both civil and military fields. Drones can be divided into three types: fixed-wing drones, unmanned helicopters and multi-rotor drones. Among them, multi-rotor drones have the advantages of controllable speed, vertical take-off and landing, and precise hovering. They have played an important role in agricultural and forestry plant protection, transportation and distribution, reconnaissance and surveillance, etc. Although with the continuous improvement of the performance of multi-rotor drones, they have shown broad application prospects in many fields, their battery life and power supply problems have not been effectively improved.

[0003] The current automatic charging platform for drone landing has poor docking performance when in use because there is a certain distance between the charging port at the bottom of the drone and the charging end of the platform. At the same time, the drone is easily affected by side winds when charging, causing the drone's position to shift and affecting the charging effect of the drone. Summary of the invention

[0004] The purpose of the present invention is to propose a wireless charging device for Beidou navigation drones in order to solve the problem that the charging port at the bottom of the drone and the charging end of the platform are at a certain distance when the drone is in use, resulting in poor docking of the drone during charging.

[0006] The docking assembly includes a positioning frame inserted on the screw rod, and guide rods are arranged on both sides of the bottom of the positioning frame. The lower end of the guide rod passes through the extension plate at the bottom of the charging plate. A spring is sleeved on the guide rod, and the two ends of the spring are respectively abutted and fixed to the positioning frame and the extension plate. Plug-in blocks are fixedly connected to both sides of the bottom wall of the positioning frame, and a threaded ring is also sleeved on the screw rod and threadedly connected to the screw rod. A plug-in groove matching the plug-in block is opened at the bottom of the threaded ring.

[0007] As a further description of the above technical solution: embedding grooves are opened on both sides of the upper surface of the charging platform, and a buffer assembly is arranged in the embedding groove. The buffer assembly includes a roller rod whose two ends are rotatably connected to the embedding groove through bearings, and a plurality of groove boxes are fixedly connected to the surface of the roller rod, and a compression rod is inserted into the interior of the groove box, the upper surface of the compression rod is fixedly connected to an outer cylinder, and the lower surface of the compression rod is fixedly connected to a plurality of supporting mechanisms.

[0008] As a further description of the above technical solution: the two ends of the two roller rods are respectively fixedly connected with a first pulley and a second pulley, the two first pulleys and the two second pulleys are respectively rotatably connected through tracks, and one of the second pulleys is connected to the output end of the second motor fixed on one side of the charging platform.

[0009] As a further description of the above technical solution: the supporting mechanism includes two buffer pads installed on the surface of the compression rod and the bottom wall of the trough box, wherein a sleeve is fixedly connected to the upper surface of one of the buffer pads, a straight rod is inserted into the inside of the sleeve, and the top of the straight rod is fixedly connected to the lower surface of the other buffer pad, and a buffer spring is sleeved on the surface of the sleeve, and the ends of the buffer spring are respectively connected to the two buffer pads.

[0011] As a further description of the above technical solution: sliding grooves are provided on both sides of the middle of the upper surface of the charging platform, and the interior of the sliding groove is rollingly connected with a pulley, and the top of the pulley is fixedly connected to the bottom of the clamping frame.

[0012] As a further description of the above technical solution: a protective pad is fixedly connected to the surface of one side of the clamping frame, and a rubber pad is arranged on the outer surface of the outer cylinder.

When the positioning frame contacts the drone, the spring is compressed downward to make the charging plate contact the charging part of the drone for charging. When the charging plate is in close contact with the charging part of the drone, the positioning frame moves downward for a distance due to the pressure of the drone, driving the plug-in block to disengage from the threaded ring, so that the charging plate stops rising, and then the charging plate is closely docked with the charging part of the drone, thereby enhancing the docking of the charging plate with the charging part of the drone;

[0017] (2) When the charging plate rises to its position, the screw continues to drive the gear disc of the positioning assembly to rotate, and the rotation of the gear disc drives the push rods on both sides to move relative to each other. When the two push rods move, they drive the clamping frames on both sides above the charging platform to move horizontally to clamp and fix the two sides of the drone, thereby preventing displacement caused by side wind during charging, thereby improving charging stability and improving charging effect.

[0034] Specifically, Figure 1 and Figure 3 As shown, it also includes a positioning component 3, which includes a toothed disc 31 fixedly mounted on the screw 15, and push rods 32 are engaged on both sides of the toothed disc 31.

[0035] The rotation of the gear plate 31 drives the push rods 32 on both sides to move relative to each other. When the two push rods 32 move, the clamping frames 33 on both sides above the charging station 1 move horizontally, thereby clamping and fixing the two sides of the drone in the middle.

[0036] Specifically, Figure 7 As shown, the two ends of the two roller rods 51 are respectively fixedly connected with a first pulley 6 and a second pulley 7, and the two first pulleys 6 and the two second pulleys 7 are respectively rotatably connected through tracks, and one of the second pulleys 7 is connected to the output end of a second motor 8 fixed on one side of the charging platform 1.

[0037] The second motor 8 drives the two second pulleys 7 to rotate, and the rotation of the second pulleys 7 drives the two roller rods 51 to rotate.

The displacement occurs, and when the screw rod 15 rotates, it also drives the threaded ring 43 to rotate. Under the limit of the plug-in block 45, when the threaded ring 43 rotates, it drives the positioning frame 41 and the charging plate 13 to rise. When the positioning frame 41 contacts the drone, the spring 44 is compressed downward to make the electromagnetic coil on the charging plate 13 contact the charging point of the drone for charging. When the electromagnetic coil on the charging plate 13 is in close contact with the charging point of the drone, the positioning frame 41 drives the plug-in block 45 to disengage from the threaded ring 43, and the charging plate 13 stops rising, thereby making the electromagnetic coil on the charging plate 13 closely docked with the charging point of the drone, thereby strengthening the docking of the charging plate 13 with the charging point of the drone.
