Wing skeleton and manual transmission device of bird-imitating manual flapping-wing flight

Abstract

The invention relates to a wing skeleton and manual transmission device of bird-imitating manual flapping-wing flight, and belongs to the field of manual bionic flapping-wing aircrafts. According to the device, a wing skeleton, a hand and foot transmission device and a rectangular back frame are combined together; and an inner wing skeleton and an outer wing skeleton of a wing are composed of two groups of special torsion springs. A group of spring handles serving as a manual device are fixedly connected to an inner arm of the torsion spring of an inner wing; both hands are sleeved on the handles and make left-and-right motions to flap the wings; the torsion spring of an outer wing is sleeved on a vertical bar at the tail end of an outer arm of the torsion spring of the inner wing; and the inner arm of the torsion spring of the outer wing is fixed on a transverse bar of the outer arm of the inner wing through the vertical bar. When the outer wing uplifts, the outer wing naturally hangs down to form a certain angle due to a specially set elasticity coefficient of the torsion spring, thereby reducing the resistance of the wing uplift. Meanwhile, a digging rope passing through a pulley sleeved on the spring handle, the knees and the feet in turn is arranged so as to enhance flapping force of the wing by pedaling the digging rope with feet. The reliable and efficient wing skeleton and manual transmission device are provided for bird-imitating manual flapping-wing flight.

AI Technical Summary

Benefits of technology

This technology allows an artificially created frog that mimics how humans communicate by feeling their muscles or bones through movement instead of relying solely upon physical movements like wheels or cranes. It also includes integrating this structure into other devices such as mannequins or vehicles' bodies. By doing things well together these structures are able to provide more accurate and effective means of transmitting forces over longer periods than just walking around them without getting tired quickly due to lacking strength from gravity alone.

Problems solved by technology

The technical problem addressed in this patented text relates to improving maneuverability during flying birds without compromising their ability to folds up into full size when they shouldn’t due to gravity forces.
