Load reducing device of backpack

Abstract

The invention discloses a load reducing device of a backpack. The load reducing device includes the backpack with a hollow back, a back plate and shoulder straps with a closed space formed by connecting the periphery of the backpack, the back plate is arranged at the lower ends of the shoulder straps, the upper ends of the shoulder straps pass through the back plate and are connected with a springdamping mechanism arranged on the inner side of the back plate, when a person walks burdened with a load, phase difference exists between the vibration of the backpack weight and the vibration of a human body, and the weight pressure borne by the human body is reduced through the spring damping mechanism. According to the load reducing device of the backpack, the weight of the heavy objects carried by the human body is skillfully utilized as damping quality, a spring damping system is formed, the difference between the natural frequencies of the spring damping system and the vibration frequencies of human body walking is utilized, so that the vibration of the heavy objects and the vibration of the human body produce a certain phase difference, the aim of reducing burden is achieved; the load reducing device is compact in structure, small in size, light in weight, easy to process and manufacture, and low in cost; the load reducing device is especially suitable for carrying a large amount of equipment in field operation, and the contradictions of having to carry a large amount of heavy objects and limited human body physical strength are effectively alleviated.

Description

technical field [0001] The invention relates to the field of human body wearable equipment, in particular to a device for effectively reducing the pressure on the human body torso when the human body is carrying heavy objects. Background technique [0002] With the modernization of national defense and the needs of scientific research, soldiers, scientific research personnel, etc. need to carry a variety of equipment in the field, such as a series of electronic equipment, batteries, etc. Heavy equipment makes the physical strength of soldiers and scientific research personnel face a severe test, which is not conducive to the smooth progress of the operation. Therefore, it is very necessary and meaningful to find a device that can reduce the burden of the heavy equipment bearer. According to the internet search, there is no method or device similar to the present invention for reducing the pressure on the torso of the human body when the human body is carrying heavy objects....
