[0002] Drones need to land regularly for charging due to long-term flight. At this time, wireless charging is more convenient than wired charging. Drones can automatically find and dock at wireless charging stations for charging, achieving unattended autonomous operation, and reducing the time required for drones to land or return for charging due to battery depletion, thereby improving operational efficiency and continuity and enabling longer monitoring and detection missions.

[0003] Patent No. CN 219687626 U discloses a wireless charging device for unmanned aerial vehicles, including a clamping soft plate, a cylinder, a fixing ring and a telescopic column, etc., and by providing a support block, a connecting column, a telescopic column, a cylinder, a telescopic spring and a clamping soft plate, the support plate is rotated under the cooperation of the support block and the connecting column, so that the clamping soft plate can be brought into contact with the surface of the unmanned aerial vehicle under the rotation of the support plate, and then by providing a threaded opening and a fixing bolt, the fixing bolt can be inserted into the threaded opening to fix the position of the connecting column rotation, so as to achieve the effect of fixing the position where the clamping soft plate contacts the surface of the unmanned aerial vehicle, which is conducive to better clamping and fixing the unmanned aerial vehicle during wireless charging, and avoids the problem that some existing unmanned aerial vehicle wireless charging devices cannot clamp the unmanned aerial vehicle well during wireless charging, so that the unmanned aerial vehicle will move when subjected to external force, thereby causing charging interruption and the inability to continue charging.

[0004] However, in use, there are the following defects:

[0005] Although a clamping soft plate is used to clamp and fix the two sides of the drone, since the sides of the drone are generally not flat and are generally equipped with wings, clamping from the side may be blocked by the wings, making it impossible to clamp stably. In addition, the bottom of the drone may be equipped with a lifting structure such as a bracket, which causes the wireless charging plate and the electromagnetic coil in the fuselage to be too far apart, affecting the efficiency of wireless charging. Utility Model Content

[0006] The purpose of the present application is to provide a wireless charging device for drones, which solves the problem raised in the background technology that since the sides of drones are generally uneven and they are generally equipped with wings, clamping from the side may be blocked by the wings, making it impossible to clamp stably, and the bottom of the drone may be equipped with a lifting structure such as a bracket, which causes the wireless charging plate and the electromagnetic coil in the fuselage to be too far apart, affecting the efficiency of wireless charging.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a wireless charging device for an unmanned aerial vehicle, comprising a supporting seat, an upper constraint plate, a lower constraint plate, a No. 2 motor and a base frame, a central groove being provided at the center of the top of the supporting seat, a No. 1 electric push rod being fixedly connected to the center of the inner bottom of the central groove, a No. 3 electric push rod being fixedly connected to the top of the No. 1 electric push rod being fixedly connected to the lower wireless charging plate, a No. 3 electric push rod being fixedly connected to the center of the outer wall of the supporting seat, a fixed frame being fixedly connected to the top of the No. 3 electric push rod, a turntable being rotatably connected to the top of the fixed frame, an extension rod being fixedly connected to the outer surface of the turntable, and an upper wireless charging plate being fixedly connected to the bottom of the extension rod, storage grooves being provided at the front and rear side edges of the top of the supporting seat, a lifting frame being vertically slidably connected to the inner side of the storage groove, and the left and right inner side walls of the lifting frame on one side of the No. 3 electric push rod are rotatably connected.

[0008] In this technical solution, before the drone lands, the lifting frame is located in the storage slot, the extension plate and the upper wireless charging plate are located on one side of the supporting seat, and according to the height of the bottom bracket of the drone, the No. 2 electric push rod is started to push the bottom bracket and the lifting frame up, and then the No. 1 motor is started to drive the upper and lower threaded rods to rotate, so that the upper constraint plates are close to each other and the lower constraint plates are away from each other, and the upper constraint plates and the lower constraint plates on the same side will clamp the drone's bracket, thereby ensuring the stability of the charging process, and the position of the upper constraint plate and the lower constraint plate can be freely adjusted according to the height and size of the drone bracket, thereby ensuring the stability of the drone during the charging process and improving the practicability of the device. The No. 1 electric push rod drives the lower wireless charging The plate moves upward until it contacts the bottom of the drone, and the lower wireless charging plate is long enough, so the drone does not need to deliberately stop in the center of the supporting plate, which facilitates the parking and charging of the drone and adapts to drones of different heights. After the drone is parked, the No. 3 electric push rod extends, and the No. 2 motor starts to drive the turntable to rotate, so that the upper wireless charging plate rotates to the top of the drone, and then the No. 3 electric push rod descends, driving the upper wireless charging plate to descend until it sticks to the top of the drone, and cooperates with the lower wireless charging plate to limit the drone from the upper and lower sides, and then the upper wireless charging plate or the lower wireless charging plate is started according to the position of the drone's wireless charging coil to start charging, which improves the stability and adaptability of the device.

[0009] As an optional solution of the technical solution of the present application, an outer strip groove is provided on the surface of the supporting seat directly below the upper constraint plate, and an inner strip groove is provided on the surface of the supporting seat directly below the lower constraint plate, and the two ends of the outer strip groove and the inner strip groove are connected to the storage grooves on both sides.

[0015] 1. The present application can clamp and fix the drone through the lifting frame, the upper constraint plate and the lower constraint plate. According to the height of the bottom bracket of the drone, the No. 2 electric push rod is started to push the bottom bracket and the lifting frame up, and then the No. 1 motor is started to drive the upper and lower threaded rods to rotate, so that the upper constraint plates are close to each other and the lower constraint plates are away from each other. The upper constraint plate and the lower constraint plate on the same side will clamp the bracket of the drone, thereby ensuring the stability during the charging process, and the position of the upper constraint plate and the lower constraint plate can be freely adjusted according to the height and size of the drone bracket, thereby ensuring the stability of the drone during the charging process and improving the practicality of the device.
