Power backpack capable of improving lateral stability of human body and reducing metabolic consumption of human body

Abstract

The invention discloses a power backpack capable of improving lateral stability of a human body and reducing metabolic consumption of the human body, and belongs to the technical field of power knapsacks. The power backpack comprises a backpack body, a first load, a second load, a sliding assembly, a motion output unit, a motion control unit and a data acquisition unit, and the first load and the second load are installed on the sliding assembly. A transmission assembly comprises a gear, a first rack and a second rack, the gear is installed at the output end of a driving assembly, and the first rack and the second rack are arranged along the opposite side faces of the first load and the second load respectively and engaged with the gear; the motion control unit controls the driving assembly to drive the gear to rotate according to the motion information to enable the first load and the second load to move in opposite phases along the sliding assembly, so that the motion amplitude of the first load and the second load is the same as the up-down motion amplitude in the human body motion process, and the motion frequency is 1 / 2 of the human body motion frequency. The lateral stability of the human body during weight-bearing walking is enhanced, and the injury risk in the weight-bearing walking process is reduced.

Description

technical field [0001] The invention belongs to the technical field of power backpacks, and more specifically relates to a power backpack that improves the lateral stability of the human body and reduces the metabolic consumption of the human body. Background technique [0002] Weight-bearing walking is a common activity in human life. For combat soldiers, the average load is 53 kilograms, and weight-bearing injuries are four times that of combat injuries. It will also lead to a decline in battlefield performance and even threaten their survival. For backpackers, students and other groups, the load is often far more than 15% of the weight of the bearer. Walking with a heavy load will greatly increase metabolic consumption, easily cause fatigue, and reduce combat capability. In addition, walking with a heavy load will also generate an acceleration force that is 2 to 3 times greater than gravity, which can easily lead to lumbar spine, muscle, joint damage and shoulder tissue c...
