Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0031] see figure 1 , figure 2 and Image 6 , the invention provides a cross-joint load-bearing support device based on a passive variable stiffness damper. The support device adopts an inverted pendulum mechanism, which uses a non-anthropomorphic design, which greatly avoids the restriction of the device on human movement. The support device includes a load support mechanism, a clutch mecha...

Abstract

The invention belongs to the related technical field of auxiliary load bearing equipment, and discloses a cross-joint load bearing supporting device based on a passive variable stiffness damper. The cross-joint load bearing supporting device comprises a load supporting mechanism, a clutch mechanism and a variable stiffness damper mechanism. The clutch mechanism and the variable stiffness damper mechanism are respectively arranged on the load supporting mechanism, and the clutch mechanism is connected with the variable stiffness damper mechanism. The supporting device is a pure passive lower limb exoskeleton, the clutch mechanism is passively triggered to be opened and closed through human body movement, and then the variable stiffness damper mechanism is locked and released in a time-sharing mode. When the supporting device is impacted or sheared, passive self-adaptive rigidity can be achieved, variable rigidity and variable damping of a damper are passively triggered through human body movement, the problems that an active load bearing exoskeleton is complex in structure and large in whole machine mass do not exist, and the problem that power energy is limited is solved.

Description

technical field [0001] The invention belongs to the related technical field of auxiliary load-bearing equipment, and more specifically relates to a cross-joint load-bearing support device based on a passive variable stiffness damper. Background technique [0002] The human weight-bearing exoskeleton device is a kind of exoskeleton robot technology equipment that can enhance the human body's weight-bearing exercise capacity, portability, maneuverability, and reduce metabolic energy consumption. It has been widely used in military, disaster relief, and military affairs. In terms of military affairs, due to the complexity of the terrain, it is difficult for large-scale mechanized vehicles to go deep into deep forests, mountain roads, stepped roads, etc. Maximize the combat capability of the troops. In disaster rescue, on the one hand, rescuers can carry a large amount of fire-fighting equipment to the scene through this device, and on the other hand, they can transfer disaster...
