Problems solved by technology

However, since this method can only weaken the force to a certain extent, the heavy objects carried by the backpack will still have speed fluctuations in the front and rear directions, and the effect is not obvious

Abstract

The invention discloses a backpack. The backpack comprises a backpack body outer layer, a backpack strap, a sliding support unit and a backpack body inner layer. The sliding support unit is arranged between the backpack body outer layer and the backpack body inner layer and fixed to the bottom of the backpack body outer layer, and the bottom of the backpack body inner layer is fixed to the sliding support unit. The backpack body outer layer and the backpack strap are connected in a sewn mode. According to the backpack, a loaded heavy object and a main frame are connected through an elastic spring so that the interaction situation between the heavy object and the human body can be improved, and the impact of the heavy object to the human body can be relieved when people walk. The rigidity matching value of the heavy object and the spring can be adjusted according to calculation, and thus energy consumed when people carry the heavy object can be reduced. Compared with previous simple design of sponge materials, the spring is adopted, higher parameter controllability is achieved, and proper springs can be selected more precisely as needed.

Description

technical field [0001] The invention relates to a knapsack, in particular to a knapsack which can make a load contact with people flexibly and reduce impact. Background technique [0002] Backpacks are very common in people's lives. Students, office workers, and travelers need to carry items such as office supplies, books, notebook computers, and food. When there are many items, the weight increases significantly. At this time, after walking for a long time with a backpack on your back, you will feel very tired, and your shoulders will be sore due to the constant force. [0003] It can be known from biomechanical research that when a person walks, because of the alternate swing and support of the legs, the upper body of the person does not move forward according to the uniform motion in physics. The movement of the human body is similar to an inverted pendulum, with fluctuations in the vertical direction, and the movement speed in the horizontal direction also fluctuates w...
