Power knapsack device assisting human body in weight-bearing walking

Abstract

The invention belongs to the field of power driving devices, and discloses a power backpack device for assisting a human body in weight-bearing walking. The device comprises a substrate, and a load, ascrew rod, an elastic rope, a data acquisition unit, a motion control unit, a power supply and a controller which are arranged on the substrate. When a human body carries the knapsack device on the back and begins to walk, the data acquisition unit acquires the acceleration of the human body in the vertical direction during movement and transmits the acquired acceleration to the controller, and the controller sets the ideal acceleration of the load in the vertical direction according to the acceleration and enables the motion control unit to drive the load to move on the lead screw at the ideal acceleration; when the human body stops, the data acquisition unit acquires the position of the load and transmits the position to the controller, and the controller enables the load to stop on thelead screw through the motion control unit. According to the invention, the metabolic energy consumption of a human body during weight-bearing walking is reduced, the shoulder pressure is reduced, and the burden on the human body is reduced.

Description

technical field [0001] The invention belongs to the field of power driving devices, and more specifically relates to a power backpack device for assisting human body to walk with a load. Background technique [0002] Carrying weight is a common activity in human daily life, especially in activities such as soldiers marching and hiking. Soldiers can carry up to 50-60kg of heavy objects when marching, and the time for carrying heavy objects can be as long as several hours or even more than ten hours. ; Also often need to carry the weight of several kilograms to more than ten kilograms and walk continuously for several hours in hiking activities. Carrying a heavy load for a long time will cause irreversible damage to the physiological structure and function of the human body and cause a huge energy consumption of the human body. Weight bearing results in increased metabolic costs to the body, increased muscle activity, and muscle fatigue, limiting the range of motion in humans...

Problems solved by technology

However, the use of traditional backpacks still consumes a lot of energy. Therefore, is there any possibility of improving the current way of carrying human beings? In this context, it is necessary to develop a wearable power backpack device that can assist the human body to bear weight. By adjusting the acceleration of the load, the energy consumption of the human body can be reduced, and the damage to the human body caused by the weight load can be reduced.

At present, there is no fully autonomous powered backpack that assists the human body to walk with weight, and it can also help researchers conduct research on human body weight.
