Description

Technical Field

[0001] This invention relates to the field of biomimetic posture technology, specifically to a flapping wing device that simulates the flight posture of birds. Background Technology

[0002] Birds' wings are generally divided into two parts: the inner wing and the outer wing. Through the active deformation of the wings, the magnitude of lift and thrust is increased during actual flight. In the principle of biomimicry, the flapping wing generates lift and thrust by flapping the wings, thereby realizing flight maneuvers such as takeoff, landing, acceleration, deceleration, rapid climb, sharp turn, hovering, inverted flight, diving, and lifting.

[0003] In the prior art, such as the "transmission mechanism of a biomimetic mechanical bird flight device" with Chinese patent number CN204279946U, there are a torso and flapping wing parts hinged to both sides of the torso and arranged symmetrically. The flapping wing parts include upper and lower support rods that are parallel to each other. Multiple main wing frames are arranged along the axial direction of the upper support rods, and the lower support rods are inserted into through holes on the main wing frames. Each flapping wing part is covered with a flapping wing shell. It creatively adopts the principle of biomimicry and combines a five-bar linkage with a crank-rocker mechanism to simulate the flapping action of a bird in flight through mechanical transmission. The biomimetic mechanical bird aircraft using this transmission device can obtain greater lift and is suitable for flight missions in complex weather or terrain. Its biggest feature is that it completely simulates the flight posture of birds in nature, and has strong stealth and fun.

The protruding part of the cam 17310 pushes the small bearing 17311 downward, causing the annular plate 1735 to drive the locking block 17312 to slide downward on the surface of the inner fixing strip 17313. At the same time, the annular plate 1735 drags the connecting rod 1734 downward, causing one end of the V-shaped connecting rod 1732 to move downward in a fan-shaped motion, resulting in the other end moving upward in a fan-shaped motion. The two cams 17310 are coaxial and achieve synchronous operation.

[0034] according to Figure 7 As shown, a power chamber 174 is fixedly connected to the left side of the fixed ring 1736.

The left end of the drive motor 165 is fixedly installed to the right end of the transmission main shaft 1739. The drive motor 165 and the transmission main shaft 1739 are connected by a coupling through bolts, providing a stable working space for the drive motor 165.

The head linkage mechanism 2 includes a head shape 21, and a linkage component 22 is fixedly connected to the middle of the head shape 21. The linkage component 22 includes a Y-shaped connecting rod 224. A long linkage rod 227 is movably connected to the upper end of the Y-shaped connecting rod 224, and a fixed shaft frame 228 is rotatably connected to the right end of the long linkage rod 227. The long linkage rod 227 is movably connected to the transmission frame assembly 16, and the Y-shaped connecting rod 224 synchronously controls the head linkage mechanism to make the bird's head move.

[0039] according to Figure 6 As shown, the outer side of the fixed shaft bracket 228 is fixedly connected to the inner side of the support column 161. The lower end of the Y-shaped connecting rod 224 is rotatably connected to the connecting plate 222, and the outer side of the connecting plate 222 is overlapped with the head connecting rod 221. Multiple head connecting rods 221 and connecting plates 222 are connected into a rhomboid frame by two hinge devices a223 and two hinge devices b225, which controls the back-and-forth movement of the head within a limited space.

[0040] according to Figure 6 As shown, a hinge device a223 is rotatably connected to the middle of the head link 221. The outer surface of the hinge device a223 is rotatably connected to the upper interior of the connecting plate 222. A hinge device b225 is rotatably connected to the lower interior of the connecting plate 222. A support block 226 is snapped onto the outer surface of the hinge device b225. The support block 226 serves as the basis for connection, with hinge structures connected to both ends. It cooperates with the rhomboid frame formed by the head link 221, the connecting plate 222, and the hinge device a223 to complete the head linkage.

[0041] according to Figure 2 As shown, a tail undulation mechanism 3 is fixedly connected to the right side of the flapping wing mechanism 1. The tail undulation mechanism 3 includes a tail wing 31. A support frame 32 is fixedly connected to the lower side of the tail wing 31. The left side of the support frame 32 is fixedly connected to the right side of the fixed frame plate 164.

[0042] according to Figure 3 As shown, the overall installation and fixing mechanism 4 includes a fixing plate 41, a connecting frame 42 is fixedly connected to the outer side of the fixing plate 41, and a connecting column 43 is fixedly connected to the lower side of the connecting frame 42; the device and the connecting frame 42 are connected through the connecting column 43, the fixing plate 41 is fixed on the carrier, and the device moves with the movement of the carrier to complete the installation.

[0043] The usage and working principle of this device: The connecting column 43 connects the device and the connecting frame 42. The fixing plate 41 is fixed on the carrier. As the carrier moves, the device moves, completing the installation. The drive motor 165 is started. The drive motor 165 is connected to the transmission main shaft 1739 by a coupling. The transmission main shaft 1739 obtains power to drive the two cams 17310 to rotate. The protruding part of the cam 17310 pushes the small bearing 17311 downward, causing the annular plate 1735 to drive the locking block 17312 to slide downward on the surface of the inner fixing strip 17313. At the same time, the annular plate 1735 drags the connecting rod 1734 downward, causing one end of the V-shaped connecting rod 1732 to move downward in a fan-shaped motion, causing the other end to move upward in a fan-shaped motion. A set of cams 17310 drives the single-hole ear block 172 to move in a fan-shaped motion, dragging the long transmission rod 1 2. Thus, the outer wing 15 is pulled by the half-angle ring 14, and the inner wing 11 is connected by the swing rod shaft 1733 to control the flapping action of the inner wing 11. The two independent cam linkage transmission components 173 respectively realize the precise control of the flapping posture of the inner wing and the outer wing. During the rotation of the cam component 1738, the ball joint 163 will be driven to roll. At the same time, the mounting base 162 will rise and fall with the rotation of the cam component 1738. The support block 226 serves as the connection base, and both ends are connected to the hinge structure. It cooperates with the rhomboid frame composed of the head linkage 221, the connecting plate 222 and the hinge device a223 to complete the up and down movement of the head. The support frame 32 supports the tail wing 31. Under the action of the flapping mechanism 1, the tail rises and falls, thus forming the flapping of the biomimetic bird wings.
