Embodiment Construction
[0026] In order to facilitate the understanding of the present invention, all technical and scientific terms used in this specification have the same meanings as generally understood by those skilled in the technical field of the present invention in conjunction with the accompanying drawings and specific embodiments. The terms used in the description of the present invention in this specification are only for the purpose of describing specific embodiments, and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more of the associated listed items.
[0027] One embodiment of the present invention relates to a compact folding wing unfolding mechanism, which can make the wing change from a folded state such as image 3 as shown, image 3 The middle base 1 and the wings 3 are in a folded state, and the wings 3 rotate rapidly around the rotating shaft at a certain angle and then lock like Figure 4...

The invention discloses a compact folding wing unfolding and locking mechanism, which comprises a machine base, a limiting and locking piece, a wing piece, a power coil spring and a cover plate, wherein the machine base comprises a square protrusion and a rotating shaft; the limiting and locking piece comprises a locking elastic piece, a supporting ring, a rotating limiting hole, a wing piece rotating braking surface and a wing piece folding limiting surface; and the wing piece comprises a locking groove, a locking surface, a bottom surface, a limiting protruding block, a wing piece coil spring installation groove, a spring cavity and a wing piece supporting ring. The compact folding wing unfolding and locking mechanism has the beneficial effects that the number of parts is small, the structure is compact, the unfolding and locking actions are reliable, gaps can be eliminated through the locking mechanism, and the internal space of a vehicle body is not occupied.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicle wing expansion, in particular to a compact folding wing expansion locking mechanism. Background technique [0002] At present, small drones are developing rapidly and are widely used in various fields. Traditional small fixed-wing UAVs are large in size, and the wings are not foldable, which makes it difficult to carry and transport. Traditional fixed-wing UAVs usually take off by taxiing or ejection, which have higher requirements on the venue or ejection conditions. Using the storage, transportation and launch integrated launcher to launch the foldable UAV can effectively solve the above problems. The UAV is folded and loaded into the integrated launch tube for storage, transportation and launch. It is convenient for storage and transportation. The UAV can be launched directly using the launch tube, which can be quickly deployed and has almost no requirements for the take-off si...
