Problems solved by technology
[0005] In order to solve the above-mentioned problems in the prior art, namely, in order to solve the existing folding-wing flapping wing, its inner section wing comprises two parallel connecting rods, and the two parallel connecting rods move mutually under the drive of the drive mechanism, and then Drive the outer wing to rotate relative to the inner wing to realize the unfolding and folding of the wing. The wing of this connection structure is relatively complicated and the weight of the wing is heavy.

The embodiment of the invention provides a folding wing ornithopter. The folding wing ornithopter comprises an ornithopter body, wings, and an elastic piece, wherein the wings are symmetrically arranged on the two sides of the ornithopter body, each wing includes a driving arm, an outer-section wing and an inner-section wing, the inner-section wing and the outer-section wing are arranged to be a sheet structure, and the inner-section wing and the outer-section wing are connected in a hinged mode; and the elastic piece is arranged below the outer-section wing and the inner-section wing and located at a hinged position of the inner-section wing and the outer-section wing, one end of the elastic piece is connected with the inner-section wing, the other end of the elastic piece is connected with the outer-section wing, and the maximum elastic restoring force of the elastic piece is equal to the gravity of the outer-section wing. In a flying process of the folding wing ornithopter, deformation of the wings, namely unfolding and folding of the wings, is achieved through an elastic force of the elastic pieces and an air resistance; and compared with the prior art, the wing structure of the folding-wing ornithopter is simpler, a parallel connecting rod is omitted for the inner-section wing, and the weight of the wings is also reduced to some extent.
Description
technical field [0001] Embodiments of the present invention relate to aircraft technology, in particular to a folding wing orchid. Background technique [0002] The orthopter uses wings to flutter up and down like birds and insects to generate upward lift, and relies on lift to fly. Wherein the wing of the folding-wing orchid can be unfolded when flapping downwards, and can be folded when flapping upwards, so that the lift force when the wings move downwards is greater than the resistance when they move upwards. [0003] The wing of existing folding wing flapper comprises outer segment wing and the inner segment wing that is hinged with outer segment wing. The inner section wing includes two parallel connecting rods, and the two parallel connecting rods are driven by the driving mechanism to move with each other, and then drive the outer section wing to rotate relative to the inner section wing, so as to realize the unfolding and folding of the wing. [0004] However, the ...
