Complete constant-force suspension backpack device with controllable damping

Abstract

The invention discloses a complete constant-force suspension backpack device with controllable damping. The device comprises a backpack connecting plate and a back plate with straps; the device further comprises two sets of constant force mechanisms and two adjusting mechanisms which are arranged in a mirroring mode, and each set of constant force mechanism comprises a lifting assembly, a first guide wheel set, a spring set, a second guide wheel set, a swing rod, a first flexible rope, a second flexible rope and a third guide wheel set; the back plate located at one end of the swing rod is connected with a fixed wheel with a wheel groove, the other end of the swing rod is provided with a pulley, the pulley and the fixed wheel are located between the backpack connecting plate and the back plate, one end of a first flexible rope is connected with the upper end of the spring set through an adjusting mechanism, the first flexible rope is sequentially erected on guide wheels of the second guide wheel set and the first guide wheel set, after bypassing the pulley from bottom to top, the other end of the first flexible rope is positioned in the wheel groove of the fixed wheel, and the other end of the second flexible rope is connected with the lower end of the spring group through an adjusting mechanism. The device can meet the requirements of different loads, can meet the movement of a human body under various frequencies, and is stable and reliable in operation.

Description

technical field [0001] The invention relates to a backpack, in particular to a controllable damping fully constant force suspension backpack device. Background technique [0002] Wearable devices are changing rapidly with the development of science and technology. How to reduce the energy metabolism of the human body is a very popular research direction at present. Backpacks are indispensable wearable equipment in daily life, but when the human body and the backpack are moving together, due to the binding, the backpack will produce inertial impact on the human body, and this inertial impact will consume more energy of the human body. It has become an urgent problem to be solved to reduce the energy metabolism of the human body and recycle the energy consumed by the human body while completing the task of carrying the load. Although foreign scientists have long proposed a suspended backpack device, the main principle of which is to decouple backpack movement from human movem...

Problems solved by technology

[0003] In order to overcome the existing technology, the present invention provides a completely constant force suspension knapsack device with controllable damping to overcome the relative displacement between the knapsack and the human body due to the up and down movement of the center of gravity when the human body is carrying a knapsack when walking or running. , and then the inertial impact on the human body is the problem of increased energy metabolism consumption of the human body.
