Abstract

The invention discloses a bionic bouncing device for an flapping wing aircraft, and belongs to the technical field of flapping wing aircrafts. The device comprises an energy storage mechanism and a bionic bouncing mechanism, partial pieces in the energy storage mechanism and the bionic bouncing mechanism form the following bionic structure: a pair of hip joints, a pair of thighbones, a pair of knee joints, a pair of tibia, a pair of ankle joints, a pair of tarsometatarsal bones, a pair of tarsometatarsal joints and a pair of phalanges; the energy storage mechanism comprises an energy storage rack, and an energy storage motor, a front-end reverse torsion structure, a rear-end reverse torsion structure, an energy storage spring, a gear transmission device and an energy storage release structure which are arranged on the energy storage rack; the bionic bouncing mechanism comprises a right bouncing mechanism and a left bouncing mechanism; the right bouncing mechanism and the left bouncing mechanism are arranged in a bilateral symmetry mode and are the same in structure. Each bouncing mechanism comprises a bouncing structure, an aircraft supporting piece and a take-off and landing buffering and stabilizing structure. The bouncing device has the advantages of being good in bouncing performance, high in bionic degree, high in environmental adaptability and the like.

Description

technical field [0001] The invention relates to the technical field of flapping-wing aircraft. Background technique [0002] As a kind of bionic flying aircraft, flapping wing aircraft has flexible use and good concealment performance, and has a very wide application prospect in national defense and military affairs. Among the flapping-wing aircraft, the bird-like flapping-wing aircraft has longer flight time and stronger load capacity, so it has more practical value. At present, with the development of science and technology, some application-oriented bird-like flapping-wing aircraft have been developed. For example, the "homing pigeon" bird-like flapping-wing aircraft detection system developed by the bionic aircraft team of Northwestern Polytechnical University has a battery life of 48 minutes. [0003] In the actual use of the bird-like flapping wing aircraft, the energy carried by it is limited, and the environment in which it is located is complex and changeable (for ...

[0005] Chinese Patent Publication No.: CN107792358A, date of publication March 13, 2018, the name of the invention is a wheel-legged running and jumping mechanism and flapping-wing robot. The leg-type running and jumping mechanism, when in use, is driven by the run-up and bounce of the wheel-type movement, so that the bird-like flapping-wing aircraft can reach the corresponding take-off speed and take-off height to take off autonomously. Accelerating to the take-off speed requires a certain rolling distance, which puts forward higher requirements on the smoothness of the take-off site and reduces the environmental adaptability of the bird-like flapping wing aircraft

Chinese Patent Publication No.: CN104015828A, publication date September 3, 2014, the name of the invention is a bionic flapping wing and bouncing multi-mode motion robot. The application discloses a bird-like flapping wing aircraft that can bounce and take off. The point is that the bouncing mechanism used is based on a multi-parallelogram mechanism, which is far from the shape of the legs of birds in nature, and the bionic effect is poor, which is not conducive to the bionic appearance of the bird-like flapping wing aircraft.

Chinese Patent Publication No.: CN104590413A, publication date May 6, 2015, the name of the invention is a bionic bouncing and walking mechanism. The application discloses a mechanism with both walking and bouncing. The bionic effect is good, but its shortcomings Yes, because the mechanism involves walking motion, the driving mechanism is relatively complicated. At the same time, the mechanism is not bionic designed according to the structure of the legs of birds in nature. If it is directly used in the bird-like flapping wing aircraft, it will lead to heavy structural weight and low efficiency in the take-off process. At the same time, due to its single-leg structure, it will cause dynamic instability of the aircraft during take-off, which will directly lead to take-off failure
