A rigid-flexible-soft coupling bionic walking wheel capable of automatically adapting to soft and hard ground environments belongs to the technical field of engineering bionics and is composed of a spoke and wheel surface integrated structure group, a wheel thorn piece group and a hub, and the spoke and wheel surface integrated structure is formed by arranging rigid-flexible-soft coupling bodies and elastic bodies at intervals; the cross section curve of the spoke and wheel face integrated structure is a bionic curve obtained by optimizing the foot sole contour line of the ostrich, and the wheel face structure can stabilize sand and limit current and improve the traction performance of the wheel. The spoke and wheel surface integrated structure can also eliminate local stress concentration and prolong the service life of the wheel; the strength and comfort of the walking wheel can be guaranteed through the rigid-flexible-soft coupling body, the mass is reduced, the contour curve of the cross section of the inner supporting plate structure is a bionic curve obtained by optimizing the contour line of the beak of a giant-mouth bird, and the effects of bending resistance, compression resistance and bearing improvement can be achieved; the elastic bodies can prevent sand and stones from entering gaps between the walking wheels.
