Embodiment １

[0032] figure 2 The overall dimensions of the mid-thigh support member are 55.6 cm in length, 21.5 cm in width, and 382.5 cm in height. image 3 The overall size of the middle and lower leg support part is 16.5cm in length, 58cm in width and 482.8cm in height. Figure 4 The overall dimensions of the middle protective cover are 130cm in diameter, 38cm in width and 2cm in thickness. Wherein the tail of the thigh support part and the head of the calf support part are respectively provided with 2 holes, and through two connecting rods, a pin shaft and a locking device, a four-bar linkage mechanism is formed to simulate normal human knee movements. Ball bearings are installed between the pin holes to reduce friction during rotation. For safety considerations, the knee exoskeleton's four-axis linkage knee joint is wrapped in a transparent protective cover. The main power source of the knee exoskeleton is a linear stepper motor, which is fixed on the hard material of the thigh su...

Abstract

The invention provides a leg exoskeleton assist and relates to thigh support parts, shank support parts, a four-link mechanism and a linear step motor; in use, the leg exoskeleton assist is worn on the outer sides of human thighs and is fixed to a user's legs by means of hook-loop fasteners, with an extreme self-locking angle introduced to the movement angle. Compared with the prior products, the leg exoskeleton assist has the advantages that the techniques and the production process are simpler and the assist has greater value in civil use.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a wearable knee exoskeleton assisting device. Background technique [0002] Existing exoskeletons can be commonly understood as wearable mechanical equipment, which has mechanical limbs and joint structures. The limbs are made of metal materials and connected by mechanical joints. Each mechanical limb is driven by a motor or hydraulic device installed at the joint. achieve a boost effect. Because the existing mechanical exoskeleton has a rigid structure and fits closely with the wearer, the movement method must be the same as that of a human being. It is a device that requires very high human-computer interaction. The technical difficulties faced in achieving smooth power assistance on the control system and power system are very complicated, so the mechanical exoskeleton is a high-tech product with high cost and low civilian value. Contents of the invention [0003] In view of...
