Wearable walking aid for old people

Abstract

The invention discloses a wearable walking aid for old people. The walking aid comprises a shank rod and a thigh rod, a first motor and a second motor are installed on the shank rod and the thigh rod correspondingly, and the output end of the first motor and the output end of the second motor are fixedly connected with a first bevel pinion and a second bevel pinion correspondingly. The first bevel pinion and the second bevel pinion are connected with a first bevel large gear and a second bevel large gear in a meshed mode, a gear shaft of the first bevel large gear is sequentially in clearance fit with a knee joint closure box and the bottom end of the thigh rod and then fixedly connected with the upper end of the shank rod, and the second motor is installed on the thigh rod. A gear shaft of the second bevel large gear is sequentially in clearance fit with two side walls of a hip joint closure box and is fixedly connected with the upper end of the thigh rod. The first motor and the second motor are used for driving the shank rod and the thigh rod to swing, power is provided for walking of the old people, and therefore the walking aid purpose is achieved.

Description

technical field [0001] The invention relates to the technical field of walking assistance devices, in particular to a wearable walker for the elderly.

Problems solved by technology

The crawler wheelchair technology is relatively mature, the operation is simple, the fluctuation of the center of gravity is relatively small, and it has strong adaptability to stairs of different sizes and shapes. However, one of the disadvantages of the crawler wheelchair is the strong pressure exerted on the edge of the stairs. There is relatively large damage to the stairs, and it is not suitable for most indoor stairs, and the crawler wheelchair itself is heavy, and the resistance to walking on the ground is relatively large. Compared with the structure of other wheelchairs, the crawler needs more power to turn the wheelchair. And during use, the noise is very loud, all these factors contribute to its low acceptance in our daily life

[0003] To sum up, the walking aids in the prior art generally have problems such as arm load-bearing, heavy weight, low flexibility of use, and inconvenient indoor activities.
