A mechanical exoskeleton seat

Abstract

The invention discloses a mechanical exoskeleton seat. The mechanical exoskeleton seat comprises a leg connecting module, a buffer angle adjusting module and a foot connecting module; the leg connecting module comprises a seat cushion plate fixedly connected with a flexible belt; the flexible belt is fixed with a wearer waist belt; a binding belt used for binding on thighs of wearers and capable of adjusting the length is fixed in a strip hole of the seat cushion plate; the seat cushion plate is fixedly connected with a first connecting rod through a length adjusting module under the seat cushion plate; the buffer angle adjusting module comprises a first connecting rod and a second connecting rod meeting the ergonomics; the first connecting rod and the second connecting rod are hinged through a first pin, and are rotationally connected; an elastic support module and an angle adjusting module are mounted in the second connecting rod; the foot connecting module comprises a foot length adjusting module fixed in a groove of the second connecting rod; the foot length adjusting module is hinged with a foot ring; and the foot ring is hinged with a foot base plate. The mechanical exoskeleton seat can improve the smoothness in the sitting process, cannot influence the human body walking, can achieve an assistance effect when the wearers stand up, and consumes no energy.

Description

technical field [0001] The invention belongs to the technical field of robots, in particular to a mechanical exoskeleton seat. Background technique [0002] Squatting and kneeling postures are bad working postures. If you work in these postures for a long time, your muscles are prone to fatigue, and injuries and diseases will occur over time. The leg support exoskeleton can support the human body when the human body squats, reducing the fatigue of the leg muscles. Existing exoskeleton seats mostly use stepping motors and lead screws to adjust the support angle, electric push rods to adjust the support angle, and dampers to adjust the support angle. However, these methods are not flexible because of the angle change when the wearer is walking. , affecting the wearer's walking. Secondly, the adjustment process is complex and requires precise control, and the motor and electric push rod need to be powered all the time. [0003] Therefore, the main problem of the existing wea...

Problems solved by technology

Existing exoskeleton seats mostly use stepping motors and lead screws to adjust the support angle, electric push rods to adjust the support angle, and dampers to adjust the support angle. However, these methods are not flexible because of the angle change when the wearer is walking. , affecting the wearer's walking

Secondly, the adjustment process is complex and requires precise control, and the motor and electric push rod need to be powered all the time

[0003] Therefore, the main problem of the existing wearable leg support exoskeleton is that the exoskeleton seat has poor adaptability to people in the two states of walking and squatting, and the angle of the exoskeleton is not flexible when walking or climbing stairs. , causing interference to the human body; the angle adjustment process is cumbersome, and energy consumption caused by electric components and other issues
