Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the wing folding and unfolding device of the small ornithopter comprises a first wing stay 1, a steering engine 2, a first gear 3 (fixedly provided with a spherical shell 3a), a second gear 4 (fixedly provided with a sphere 4a and a spring 4b), a second wing stay 5, a stay connecting rod 6, a third wing stay 7 and a fourth wing stay 8; first gear 3 is installed on steering wheel 2, can rotate through steering wheel 2's drive, and steering wheel 2 is fixed in first wing stay 1, and second gear 4 meshes with first gear 3 mutually, and the gear ratio is 2: 1, a second gear 4 is fixed on a second wing stay 5, and the first wing stay 1 is hinged with the second wing stay 5 and meshed with the second wing stay 5 through a gear to rotate mutually; the third wing stay 7 is hinged with the second wing stay 5 through the stay connecting rod 6, one end of the third wing stay is hinged with the first wing stay 1, the third wing stay 7 can be driven to rotate through the rotation of the second wing stay 5, and the fourth wing stay 8 is fixed on the first wing stay 1.
As shown in figure 1, the steering engine 2 can rotate to drive the second wing stay 5 and the third wing stay 7 to rotate, so that the wings can be unfolded and folded, and the steering engine is driven by the gear reduction set to save more labor and be stable.
As shown in fig. 1, when the steering engine 2 rotates until the second wing stay 5 and the first wing stay 1 are coaxial, the rotation is stopped, the wing is completely unfolded, the self-locking devices on the first gear 3 and the second gear 4 can be locked right, and the self-locking devices are engaged with the gears to limit the wing, so that the unfolded structure of the wing is kept stable.
