Technical Field

[0001] The utility model relates to a centering and clamping device for an unmanned aerial vehicle (UAV). Background Art

[0002] With the rapid development of UAV technology, its applications in fields such as aerial photography, agriculture, plant protection, disaster rescue, wildlife observation, infectious disease monitoring, mapping, news reporting, power line inspection, disaster relief, and film shooting have greatly expanded the uses of UAVs themselves. In order to achieve the unattended automatic takeoff and landing function of UAVs, through auxiliary means such as image recognition and RTK positioning functions, the UAV is parked at the target position of the predetermined apron.

[0008] Further, one of the X-direction screw slider mechanisms is equipped with an X-direction screw motor, while the other X-direction screw slider mechanism is not equipped with an X-direction screw motor. The two X-direction screw slider mechanisms are connected by an X-direction synchronization component. The X-direction synchronization component includes X-direction synchronization wheels respectively arranged on the ends of the X-direction screws of the two X-direction screw slider mechanisms.

[0033] In an embodiment of the present utility model, in order to facilitate moving, a handle 10 is installed on the bottom plate.

[0034] In an embodiment of the present utility model, during operation: when the drone lands on the parking pad, the X-direction driving mechanism drives two X-direction clamping rods to move relatively, and the Y-direction driving mechanism drives two Y-direction clamping rods to move relatively, so as to clamp and center the drone, thereby avoiding the problem of parking error of the drone and enabling the drone to park at a designated position; when the drone needs to take off, the X-direction driving mechanism drives two X-direction clamping rods to move away from each other, and the Y-direction driving mechanism drives two Y-direction clamping rods to move away from each other, so that the drone can take off smoothly.

[0035] Embodiment 2: On the basis of Embodiment 1, in an embodiment of the present utility model, an X-direction optoelectronic patch 11 is arranged inside the X-direction screw slider, and two X-direction optoelectronic switches 12 are arranged on the X-direction guide rail.

[0038] When the UAV is ready to take off from the platform, the X-axis servo motor of the X-axis drive mechanism is powered on to start providing power, and the two X-axis sliders move synchronously away from each other, driving the X-axis clamping mechanism to separate and expand. When the X-axis slider drives the X-axis photoelectric patch to move to the starting point and the X-axis photoelectric switch at the starting point is blocked, the servo motor stops moving, and the X-axis expansion movement is completed; Similarly, subsequently, the Y-axis lead screw motor of the Y-axis drive mechanism is powered on to start providing power, driving the two Y-axis sliders on the two Y-axis lead screws to move synchronously away from each other, thereby driving the Y-axis clamping mechanism to separate and expand.

[0039] In addition, a UAV charging module can be installed on the X-axis clamping mechanism and the Y-axis clamping mechanism to clamp and charge the UAV after it lands, thereby ensuring the endurance of the UAV.
