Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle accessories, and in particular to a mounting device for an unmanned aerial vehicle. Background Art

[0002] With the development of drones, in some mountainous agricultural harvesting, drones are used to transport fruits from the mountain to the foot of the mountain. Drones can transport fruits in a straight line over the mountain more quickly, without the need to walk on rugged mountain roads, thus speeding up transportation efficiency and shortening transportation time.

[0003] The drone is connected to the cargo straps through hooks and other devices. The hooks need to be manually connected to the cargo straps by personnel. It is dangerous for personnel to operate a hovering drone. In particular, in order to reduce the swaying during movement, the distance between the drone and the hook will not be particularly long, resulting in a closer distance between personnel and the drone, further increasing the danger.

After the second mounting frame performs item strap fixation, the lower connecting column is docked and fixed with the second mounting frame as the drone descends, eliminating the need for personnel to manually dock the lower connecting column with the second mounting frame, and eliminating the need for personnel to perform docking operations under a hovering drone, which is safer for personnel.

After the first mounting frame and the second mounting frame are separated, the external counterweight block presses down the upper limit frame and rotates it outward, and the side guide ring tilts upward. The lower connecting column moves down to dock with the top groove of the second mounting frame, and the side guide ring is pressed down synchronously. The lower magnetic block and the upper magnetic block are adsorbed with opposite magnetic poles, the upper connecting port and the lower connecting port are vertically docked and electrically connected, and the lower connecting port is electrically connected to the second electric telescopic cylinder.

[0008] In at least some embodiments, the two ends of the lower connecting column are fitted with the upper grooves of the second mounting frame, and when the limit pin and the side hole of the upper limit frame are slidably inserted, the upper limit frame is fitted on the upper part of the lower connecting column, and the upper limit frame is rotated and pressed down on the top of the lower connecting column. The first electric telescopic cylinder is extended to push the limit pin and the upper limit frame to slide, and the position of the upper limit frame is fixed.

The lower connecting column 105 is docked and fixed with the second mounting frame 2 as the drone descends, eliminating the need for personnel to manually dock the lower connecting column 105 with the second mounting frame 2, eliminating the need for personnel to dock under the hovering drone, making personnel safer, eliminating the time for waiting for the drone to land, reducing the take-off and landing time of the drone, shortening the mounting time, further shortening the distance between the drone and the lower mounted cargo, reducing the swaying and sliding of the drone cargo during movement, and reducing the unmanned operation pressure;

[0036] The upper connection port 103 and the lower connection port 204 are magnetically attracted to each other by the lower magnetic block 205 and the upper magnetic block 104 to ensure a snug connection. The upper connection port 103 and the lower connection port 204 ensure a snug fit for electric contact. At the same time, the magnetic attraction of the upper connection port 103 and the lower connection port 204 facilitates smooth separation as the first mounting rack 1 and the second mounting rack 2 are separated, thereby avoiding obstruction in the separation of the first mounting rack 1 and the second mounting rack 2.
