Wearable upper limb exoskeleton power-assisting device

Abstract

The invention discloses a wearable upper limb exoskeleton power-assisting device. The wearable upper limb exoskeleton power-assisting device comprises mechanical arm devices, a supporting device and gripping devices, wherein each mechanical arm device comprises a pedestal, a power assembly and an arm assembly; each arm assembly 13 is a main holding part of each mechanical arm device 1; motion of each arm assembly 13 is realized by each power assembly 12; each power assembly 12 drives the corresponding arm assembly 13 to perform space motion for feeding a hand to any point within a space motion range. Through the unique mechanical structure design, free extension of the arms is realized, so that the arms have a state of relaxing and stretching and a state of lifting forearms, and are freely transited between the two states. The wearable upper limb exoskeleton power-assisting device is reasonable in structure, is relatively high in practical value, can improve ability of people, can realize carrying heavy objects easily, and relieves working strength of a worker.

Description

technical field

[0001] The invention relates to a power assist device, in particular to a wearable upper limb exoskeleton power assist device. Background technique

[0002] Existing mechanical exoskeletons have mechanical limbs and joint structures. The limbs are made of metal materials and connected by mechanical joints. Each mechanical joint is driven by a motor or hydraulic device installed at the joint. The mechanical joints drive the mechanical limbs to drive the wearer's limbs Sports, so as to achieve the effect of assisting, is a kind of equipment that requires very high human-computer interaction. The research purpose of the upper extremity exoskeleton robot is to increase the energy of the upper limbs, thereby enhancing the human ability, so that it has greater force and energy when lifting heavy objects. And when the upper limb exoskeleton robot assists people to perform actions, the accuracy of the action position must be ensured to avoid harm to people or other ...
