Knapsack device with dynamic load reduction and energy capture capabilities

Abstract

The invention discloses a knapsack device with dynamic load reducing and energy capturing capabilities. The knapsack device comprises a knapsack with a hollow back, a back plate, sliding devices and shoulder straps. The device has multiple working modes, when the device is in a load reduction or power generation mode, the back plate is attached and fixed to the back of a human body, the lower endsof the shoulder straps are connected with the back plate, the upper ends of the shoulder straps are connected with ends of inhaul cables, and the shoulder straps are connected with spring damping mechanisms in the knapsack through the inhaul cables. By adjusting the internal connection of the spring damping mechanisms, a load reduction mode or a power generation mode can be switched; in a commonmode, the upper ends of the shoulder straps are connected with the knapsack upper half part, and the lower ends are connected with the knapsack lower half part, thereby realizing mode conversion. Thespring damping mechanisms capable of switching the spring stiffness coefficients is ingeniously arranged, different spring stiffness coefficients are matched for loads with different masses, the spring damping mechanisms and the sliding devices are used for enabling backpack vibration and human body vibration to form phase difference and displacement difference, and the purposes of load reductionand power generation are achieved.

Description

technical field [0001] The invention relates to the field of human body wearable equipment, in particular to a backpack device capable of reducing dynamic load and capturing energy. Background technique [0002] At present, soldiers are carrying more and more equipment, which puts forward high requirements on the physical fitness of soldiers. When the human body walks, the center of gravity of the human body will form a periodic displacement in the vertical direction. Due to this displacement, the pressure exerted by the heavy object on the human body will become a dynamic force that changes with the walking cycle, fluctuating up and down in the gravity value of the heavy object, and the peak pressure can reach 2 to 3 times the gravity value of the heavy object. In addition, the application of more and more high-tech equipment in individual soldiers has also increased the demand and dependence on electric energy. The power guarantee of individual soldiers has become one of...
