Energy collection and load reduction backpack based on friction electricity generation

Abstract

The invention provides a suspended energy collection and load reduction backpack based on friction electricity generation, and belongs to the technical field of luggage application. The suspended energy collection and load reduction backpack comprises a backpack body, backpack straps, a backpack upper plate and a backpack bottom plate; a weight reducing buffer unit, a layer type linkage friction electricity generation unit and a pair of sliding rod fixing units are arranged between the backpack upper plate and backpack bottom plate; through the pair of sliding rod fixing units, the relative sliding occurs between the backpack upper plate and the bottom plate in the sliding rod direction; and the weight reducing buffer unit transmits the acting force to the layer type linkage friction electricity generation unit through the backpack upper plate to drive the mutual linkage of all actuators in the layer type linkage friction electricity generation unit, the bio mechanical energy is converted into electric energy for storage, and the weight reducing buffer unit is used for significantly reducing the absolute amplitude of the load when people move so that the effect of load reduction, shock absorption and physical strength saving is achieved. The suspended energy collection and load reduction backpack is compact in structure, various in functions, convenient to adjust, safe and reliable, and can collect energy while effectively reduce the load and shock absorption.

Description

technical field [0001] The invention relates to the technical field of luggage application, in particular to an energy collection and load reduction knapsack based on frictional electricity generation. Background technique [0002] While backpacks bring convenience to people in daily life, they also release the freedom of hands. Because of their convenience and practicality, backpacks are widely used. However, ordinary backpacks have a common problem, that is, the heavy objects they carry will float up and down with the ups and downs of the center of gravity such as walking and running. Human body energy, even when heavy objects reach a certain weight, will seriously affect the movement of the human body. Therefore, exploring a knapsack device for decoupling the knapsack and human body movement during the ups and downs of the human body's center of gravity, and breaking the phase synchronization between the knapsack and human body movement can reduce or eliminate the useles...

Problems solved by technology

The disadvantage of this backpack is that the spring-type load-reducing mechanism can reduce weight and buffer, but it adopts the form of four springs, three springs on the top and one spring on the bottom, so that the elastic force of the lower spring is not stable and the upper middle spring and the left and right springs are easily separated. The formation of over-positioning affects the balance of carrying heavy objects; at the same time, the iron rack and pinion used to drive the motor and the motor will inevitably increase the weight of the backpack frame significantly

The disadvantage of this backpack is that the schoolbag adopts the method of adjusting the size of the vertical and horizontal storage space in the schoolbag, and the backpack is closely attached to the shoulder and back by the stretch belt structure and the telescopic structure. Tightening, the adjustment range is limited, and when the load fluctuates up and down during the carrying process, the telescopic structure is subjected to cyclic force, which is insufficient in safety and stability, and the degree of load reduction and labor saving is insufficient.
