Abstract

The invention provides a toe-web collaborative variable-area anti-subsidence bionic foot and a bionic machine. The toe-web collaborative variable-area anti-subsidence bionic foot comprises a flange plate, a vertical sliding block, a connecting rod, a horizontal guide rod, a horizontal sliding block, a foot web, a support, a spring and a vertical guide rod. When the bionic foot touches the ground, under the action of self gravity, the flange plate pushes the vertical sliding block to compress the spring to move downwards along the vertical guide rod, the connecting rod is driven by the vertical sliding block to rotate and pushes the horizontal sliding block to move outwards along the horizontal guide rod, the foot web is driven by the adjacent horizontal sliding block to enlarge the ground contact area, and the anti-sinking function of the bionic foot is achieved. According to the anti-subsidence foot type moving mechanism, the movement functions that the area is enlarged when the foot type moving mechanism touches the ground and the foot type moving mechanism is restored when the foot type moving mechanism leaves the ground are achieved, the subsidence problem of the soft and slippery ground such as mud flat is solved, and a new solution is provided for design of the anti-subsidence foot type moving mechanism on the soft and slippery ground.

Description

technical field [0001] The invention belongs to the technical field of engineering bionics, and in particular relates to a toe-web cooperative variable area anti-subsidence bionic foot and a bionic machine. Background technique [0002] The tidal flat is a typical soft and slippery ground. Due to the poor ground bearing and shear resistance, the wheeled mobile mechanism is prone to problems such as slipping, subsidence and insufficient traction when moving on the tidal flat. Compared with the wheel type, the crawler type mobile mechanism has high passability on tidal flats, but the mass of the crawler chassis is large, the turning radius is large, and the flexibility is poor. Therefore, the key to realizing mechanized operations in agriculture, forestry, animal husbandry, fishery, reed, salt and other industries on tidal flats is to solve the problem of the passability of mobile mechanisms. [0003] Compared with wheel-type and crawler-type mobile mechanisms, due to the dis...
