Problems solved by technology

As an important component, the clutch device is often indispensable, but general clutches, including friction clutches, hydraulic couplings, electromagnetic clutches, etc., are very heavy under the high torque index, and it is difficult to meet human needs. Wearing needs, or need more power to support their own weight

Embodiment Construction

[0030] specific implementation plan

[0031] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0032] The invention mainly discloses a walking assist device, which reduces the weight of the device itself and increases the torque capacity. At the same time, the invention also designs a clutch device, which is composed of components such as a ratchet wheel and a pawl.

[0033] Such as figure 1Shown is a side view of an embodiment of a walking assist device of the present invention. The figure shows the base part, the thigh part, the calf part, the schematic diagram of the foot part, and also indicates the front and back aspects of wearing the device, the vertical axis direction and the sagittal axis direction. Only one leg assembly is assembled in the figure, that is, a thigh section, a calf section, and a foot section.

[0034] The base part, the base part is placed on the wearer's ...

Abstract

The invention discloses a walking assisting device. The device comprises a base part, a thigh part, a shank part, a foot part and a clutch device, and requirements for large torque and low weight are met. The clutch device is specially designed to reduce the weight of the device and increase the bearable torque of the device during working. The device provides upward pushing force for a wearer by the aid of the saddle-type base part located at the crotch of the wearer, so that pressure on both feet and both knees of the wearer is reduced, and the walking assisting effect of convenient walking is realized. Torque is output by a motor to drive assemblies such as a speed reducer, the clutch device and the like, an included angle formed by a thigh and a shank is enlarged, rotating torque is formed, and the base part is lifted. The clutch device adopts a ratchet wheel and pawl structure, and one-way or two-way clutching can be realized. The device provides walking assistance for people having difficulty in walking.

Description

technical field [0001] The patent of the present invention belongs to the field of intelligent auxiliary devices, and specifically relates to a wearable mechanical exoskeleton device. Background technique [0002] Walking is a basic action in people's daily life, but with people's natural aging or disease or trauma, people's walking ability declines, which directly affects people's quality of life. Assistive walking devices help people with reduced walking ability, including crutches, wheelchairs, prosthetics, orthotics, and more. With the development of technology, passive structures are gradually endowed with initiative and intelligence. Electric wheelchairs and crutches with sensors gradually appear. At the same time, mechanical exoskeletons have also been developed as a new power-assisted device. As a mechanical exoskeleton, wearability is an important challenge, that is, the weight should be as light as possible, the power assistance method should be reasonable and eff...
