Energy-saving walking leg mechanism simulating ostrich hindlimb movement function characteristic

Abstract

The invention discloses an energy-saving walking leg mechanism simulating ostrich hindlimb movement function characteristic. The energy-saving walking leg mechanism comprises a rack, a crank connection rod mechanism, a rebounding mechanism and a toe, wherein the crank connection rod mechanism comprises a crank, a thigh and a rocking rod; the rebounding mechanism comprises a fixed sliding block, a crus, a movable sliding block, a connection rod, a spring, a baffle plate, a ratchet mechanism, a brake cable, an angle limiter and metatarsal bones. The energy-saving walking leg mechanism is designed on the basis of the size parameters of the ostrich hindlimb and the rebounding characteristics of joints between ostrich tarsal bones; an energy-saving and efficient walking leg is designed by simulating the ostrich hindlimb movement; the metatarsal bones automatically stretch by using the rebounding force generated by compressing the spring, so that the energy loss is reduced; the energy-saving and efficient walking leg simulating ostrich hindlimb movement function characteristic can achieve the energy-saving and efficient purpose.

Description

technical field [0001] The invention belongs to the field of robots, and relates to an energy-saving walking leg mechanism imitating the motion function characteristics of ostrich hind limbs. Background technique [0002] Ostriches are the fastest bipeds in the world. Studies have shown that when the angle between the lower leg and the metatarsal is greater than 108° during the stretching of the ostrich leg from the bent state, the ostrich metatarsal will automatically stretch. This passive stretching process can save the energy consumption of the ostrich's movement. At the same time, the running speed of an ostrich in the desert can reach 50-60Km / h, and can last for 30 minutes. Due to the energy-saving and high-speed characteristics of ostrich movement, ostriches are superior to other bipeds in terms of speed and energy conservation. According to the principle of engineering bionics, the superior performance of ostrich can be applied to the design of biped robot. The "S...
