Abstract

The invention provides an unpowered lower limb exoskeleton robot. The robot comprises a shoe body comprising a vamp and a sole, a shank sheath and an ankle joint clutch mechanism, wherein a first cavity is formed inside the end, close to the heel, of the sole; a first channel is formed in the vamp and is communicated with the first cavity; and the ankle joint clutch mechanism comprises an ankle joint protective sheath, a fixed box, a first elastic part and the like. According to the robot, a sealed chamber is inflated by air in the first cavity through the channel and an airway tube in a userwalking process, so that a slide block and a one-way toothed bar are pushed; from the middle stage of a swing phase to the initial stage of a supporting phase, the ankle joint performs dorsiflexion, avariable stiffness spring is stretched, the one-way toothed bar moves downwards to store the gait energy of the ankle joint; and under the contraction effect of the variable stiffness spring, the ankle joint is pulled by the one-way toothed bar to make toe flexion to assist a human body in gait walking, so that the energy in the gait process can be utilized to the maximum extent, the utilizationefficiency of the gait energy can be improved, and the metabolic energy consumption in the walking process of the human body can be reduced.

Description

technical field [0001] The invention relates to the technical field of rehabilitation robots, in particular to an unpowered lower limb exoskeleton robot. Background technique [0002] The unpowered lower extremity exoskeleton uses gait energy as the energy source to achieve low metabolic energy consumption, high self-adaptation, and continuous and stable walking. The prior art discloses a non-powered energy storage paraplegic walking aid exoskeleton. This device can provide precise walking aids for paraplegic patients with different heights, weights and injuries. Different users carry out optimization design of spring stiffness parameters. The prior art also discloses a non-powered lower extremity exoskeleton robot, which includes waist, thigh, knee joint, calf and foot connected sequentially from top to bottom. The waist provides a slide rail for the pulley to rotate, improving the flexibility of movement. The waist has 3 degrees of freedom, which can ensure the flexibili...
