Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Such as Figure 1-6 shown.

[0025] A flexible lower limb exoskeleton combining active and passive combined strength, which includes foot 1, calf 3, thigh 5 and back frame 7, the length of calf 3 and thigh 5 is adjustable, and the connection between foot 1, calf 3 and thigh 5 and the human body in the same way as existing exoskeletons, such as figure 1 As shown, a solar device 8 for charging the battery on the back is installed on the back frame 1, and the calf 3 is rotatably connected with the foot 1 through the ankle joint 18. The lower end of the calf 3 is connected with an ankle joint pressing plate 9, and the ankle joint pressing plate 9 It counteracts with the ankle joint spring 2 for foot assist, the ankle joint spring 2 is installed in the spring seat 201, and the spring seat 201 is fixedly connected with the foot 1 (plantar plate),...

Abstract

The invention relates to a driving-and-driven combined boosting type flexible lower limb exoskeleton. The driving-and-driven combined boosting type flexible lower limb exoskeleton comprises a foot (1), a shank (3), a thigh (5) and a back frame (7), and the shank (3) is rotatably connected with the foot (1) through an ankle joint (18). The driving-and-driven combined boosting type flexible lower limb exoskeleton is characterized in that the lower end of the shank (3) is connected with an ankle joint pressing plate (9), the ankle joint pressing plate (9) abuts against an ankle joint spring (2) for foot boosting, the ankle joint spring (2) is installed in a spring base (201), and the spring base (201) is fixedly connected with the foot (1); the upper end of the shank (3) is hinged to the lower end of the thigh (5) through a knee joint (19); the upper end of the thigh (5) is connected with the back frame (7) through a hip joint (6). The driving-and-driven combined boosting type flexible lower limb exoskeleton is simple in structure and convenient to control.

Description

technical field [0001] The invention relates to an exoskeleton structure with a power-assist function, in particular to an exoskeleton capable of improving the walking distance of a human body, in particular to an active-passive combined force-increasing flexible lower limb exoskeleton. Background technique [0002] Exoskeleton refers to the hard exterior that provides protection and support for organisms. It originally refers to the bones on the outer surface of insects or crustaceans, which have support and protection functions. Exoskeleton robots refer to robots that are placed outside the human body. Exoskeleton robot technology is a comprehensive technology that integrates sensing, control, information, mobile computing, energy, materials, and machinery to provide operators with a wearable mechanical mechanism. Wearable lower extremity exoskeleton robots can provide assistance to soldiers, effectively improving the carrying and combat capabilities of individual soldiers...
