A non-powered bendable waist booster

Abstract

A non-powered bendable waist booster, which belongs to the field of robots for helping the elderly and the disabled, includes a multi-axis single-degree-of-freedom mechanism I, a position fixing mechanism II, a driving mechanism III, and a strap IV. The strap IV includes shoulders, waist and Knee straps. The position fixing mechanism II is set on the waist strap, which is used to lock the upright state when the upper body is upright, and unlock the upper body when bending over. The top of the multi-axis single-degree-of-freedom mechanism I is fixed to the shoulder strap, and the bottom is connected to the position-fixing mechanism II. The multi-axis single-degree-of-freedom movement is realized through the row of toothed connecting rods, and the human spine remains in a state of fit from bending to upright. The driving mechanism III is set at the knee strap position, and is bound to the upper end of the multi-axis single-degree-of-freedom mechanism I through the position-fixing mechanism II, and the multi-axis single-degree-of-freedom mechanism is pulled by the driving mechanism III during the process of the knee from bending to straightening Ⅰ, to provide assistance. The invention has simple structure and relatively complete functions, adopts no power assist, and can provide assist for waist transportation by bending the knees, and is convenient to use.

Description

technical field [0001] The invention belongs to the field of robots for helping the elderly and the disabled, and provides a bendable waist booster. Background technique [0002] At present, in the field of robot technology for helping the elderly and the disabled, there are three technical solutions for providing assistance to the waist of the human body: the first is a fixed waist belt containing steel sheets, which can provide effective support for the waist, but also for the waist. Movement of the spine is restricted so that it cannot flex normally. The second type is a waist hinge drive mechanism with a single rotary axis. Although it can provide assistance when bending over, it cannot always achieve a bending deformation consistent with the spine during the bending process, resulting in the mechanism not being able to maintain a good close fit with the body. It cannot ensure its support effect on the waist. The third type is a soft inflatable deformable airbag struct...

[0002] At present, in the field of robot technology for helping the elderly and the disabled, there are three technical solutions for providing assistance to the waist of the human body: the first is a fixed waist belt containing steel sheets, which can provide effective support for the waist, but also for the waist. Restricted movement of the spine so that it cannot flex normally

The second type is a waist hinge drive mechanism with a single rotary axis. Although it can provide assistance when bending over, it cannot always achieve a bending deformation consistent with the spine during the bending process, resulting in the mechanism not being able to maintain a good close fit with the body. fit, cannot ensure its support effect on the waist

The third type is a soft inflatable deformable airbag structure, which generally has the disadvantages of large volume, difficult shape adjustment, and inaccurate motion control.
