Abstract
Description
Technical Field
[0001] The present invention relates to an integrated reconfigurable multi-legged closed-chain platform, specifically a high-mobility closed-chain foot-type walking platform with a leg group having two reconfigurable deformation modes; that is, the reconfigurable deformation of the leg group has two modes, and the multiple legs can achieve support and climbing in different modes, thereby having better climbing and obstacle-crossing capabilities. Background Art
[0002] The closed kinematic chain is applied to the leg mechanism of the walking platform, and each leg mechanism is driven by an independent motor. Compared with the open-chain leg, under the conditions of the same material, external load and speed level, the closed-chain rod system theoretically only bears tensile and compressive loads, and most of them are typical two-force rods, which makes the closed-chain leg mechanism have good stiffness and stability as a whole.
[0003] Chinese patent CN109178133A discloses "a variable topology operation dual-mode walking mechanism". The device changes the foot end gait and lifting height of the walking mechanism by changing the two structures of the variable topology walking mechanism. The two modes of walking ensure the adaptability of the walking mechanism to complex ground and improve the obstacle crossing ability of the walking mechanism. The walking mechanism structure change is completed by the motor-driven block, and a carrying device that uses a variable topology closed-chain connecting rod mechanism to achieve mountain walking and obstacle crossing is a simple and reliable mechanism with strong adaptability and stability. Summary of the invention
[0004] The problem to be solved by the present invention is to provide a walking platform, which, compared with the existing walking platforms, can improve the climbing and obstacle surmounting ability of the walking platform through the reconstruction and deformation of the leg group and the pitching of the trunk; the reconstruction of the front legs occurs during the climbing process, while the reconstruction of the hind legs occurs during the supporting process; these two reconstruction strategies are completely separated in the time domain, so a grooved wheel mechanism is designed to realize dynamic coupling under single degree of freedom, so that the reconstruction deformation of the front and rear legs does not interfere with each other. During the climbing process, the two front electric push rods extend to drive the groove wheel front leg heavy structure to move, and the front legs of the front leg group also make a lifting action accordingly, thereby realizing the climbing action of the front leg group; after the front leg group successfully climbs, the height difference between the positions of the front and rear leg groups forms the pitch of the platform trunk, at this time, the two front electric push rods contract to drive the groove wheel rear leg heavy structure to move, and the two rear electric push rods extend to drive the groove wheel rear leg heavy structure to move, and the reconstruction of the rear legs on both sides is the deflection of the horizontal angle of the platform for angle compensation; finally, the two rear electric push rods extend to drive the groove wheel front leg heavy structure to move, and the front legs of the rear leg group also make a lifting action accordingly, completing the climbing action of the rear leg group; through the above-mentioned mechanism movement, the climbing of the entire platform is realized.
