Safety crutch for elderly

Abstract

The invention discloses a safety crutch for the elderly. The safety crutch comprises a crutch main body, a controller and an air cushion induction device, wherein the controller is arranged inside a grab handle of the crutch main body, a pressure sensor used for sensing the grip strength of the grab handle when a user falls over and a gravity center induction sensor used for sensing the own gravity center of the crutch when the user falls over are arranged outside the grab handle of the crutch main body; the pressure sensor and the gravity center induction sensor are connected with the input end of the controller; the air cushion induction device comprises sensing support rods arranged at the bottom end of the crutch main body and used for sensing the falling direction and an airbag device arranged inside air jet mouths in the bottom end of the crutch main body. After the user falls over, the pressure sensor senses the grip strength of the grab handle when the user falls over, the gravity center induction sensor senses changes of the own gravity center of the crutch when the user falls over, the sensing support rods are used for sensing the falling direction of the user, comprehensive analysis is performed by the controller, and set parameters are reached, so that the controller and the air cushion induction device work.

Description

technical field [0001] The invention relates to an intelligent crutch, in particular to a safety crutch for the elderly. Background technique [0002] A cane is a simple walking aid, usually a wooden or metal stick.

Problems solved by technology

Although crutches can assist people to walk, users will still fall for some reason, and general crutches cannot play a certain role in safety protection at all.

Moreover, in areas with poor light at night, it is inconvenient for the elderly or the disabled to walk. At the same time, on the road, the motor vehicle drivers in front are not easy to notice, which is likely to cause traffic accidents
