Anti-fall self-adaptive rollator and working method

Abstract

The invention discloses an anti-fall self-adaptive rollator and a working method, which comprises two left and right lifting arms, the lower ends of the two lifting arms are hingedly connected with the left and right vertical rods respectively, and the two lifting arms The upper part of the top plate is respectively connected with both sides of the top plate, and the middle part of the bottom surface of the top plate is hingedly connected with the lifting link; The middle part of the rod is hinged. The middle part of each lifting arm is hingedly equipped with a lifting motor; the lower end of the screw rod of the lifting motor is hingedly connected with the lower part of the vertical rod on the same side. The rollator can lift the user from a sitting state to a standing state or help the user to change from a standing state to a sitting state. The chassis is equipped with electric wheels and force sensors. The electric wheels can move forward, backward, turn left and right, and rotate in situ according to the results of sensor detection and judgment; thereby assisting the user in walking, turning, and correcting body posture when falling.

Description

technical field [0001] The invention relates to the technical field of walking aid vehicles, in particular to an anti-fall self-adapting rollator. Background technique [0002] At present, with the aging of the population, the physical strength and balance ability are weakened, the risk of "unsteady" falls increases, and there is a lack of effective auxiliary support devices. Some elderly people need to use walkers, crutches or rollators when traveling and exercising. When using appliances and crutches, it is necessary to move the appliances intermittently. [0003] A rollator is a device used to assist walking by supporting the body of an elderly or patient with limited mobility through a mechanical device. At present, most of the existing rollators on the market are four unpowered universal wheels. As the user pushes and supports the user to walk, there are brake handles controlled separately on the left and right sides at the handle position. The user cannot control its...

AI Technical Summary

Problems solved by technology

At present, most of the existing rollators on the market are four unpowered universal wheels. As the user pushes and supports the user to walk, there are brake handles controlled separately on the left and right sides at the handle position. Users cannot control their walking and braking well during use. When the center of gravity is unstable or when the body is tired after walking for a period of time, accidents such as falling may occur due to limb weakness.
