Backpack

Abstract

The invention provides a backpack comprising a bag body, a moving support for supporting and fixing the bag body, a back plate for supporting the back of a human body, two shoulder straps connected with the back plate, and a buffering mechanism used for reducing the vibration amplitude of the backpack in the vertical direction; the buffering mechanism comprises a linear sliding rail assembly for guiding the moving support to move up and down on the back plate and an elastic element which is connected with the back plate and the moving support and plays a damping buffering effect, one end of the elastic element is connected with the moving support, and the other end of the elastic element is connected with the back plate. In the process of walking motion with the human backpack being loaded, the linear sliding rail assembly guides the bag body loading a heavy object to reciprocate in the vertical direction, and the vibration amplitude generated by the up-down reciprocating motion of thebag body is reduced through the action of the damping force of the elastic element, so that the impact force of the shoulder straps on the shoulders of the human body is well buffered, the compression force of the backpack on the shoulders is reduced, and fatigue damage caused to the shoulder muscles by the backpack is avoided.

Description

technical field [0001] The invention belongs to the technical field of human body wearable devices, and more specifically relates to a backpack. Background technique [0002] Currently, the shoulder straps of most backpacks are fixed on the back of the backpack. When hiking, traveling, climbing or performing sports training, the backpack reciprocates up and down with the walking movement of the human body, and produces relatively large up-and-down vibrations in the vertical direction, causing the shoulders of the human body to bear greater pressure. The compressive force is affected by the gravity of the backpack load and the downward acceleration of gravity. The more intense the movement of the human body, the greater the range of movement of the backpack, which may even cause the backpack to form a stronger impact on the shoulders of the human body, causing shoulder muscle soreness. Increase the fatigue of the human body, and often feel difficult to carry. Contents of t...

Problems solved by technology

[0003] The object of the present invention is to provide a backpack, aiming at solving the problem in the prior art that the backpack vibrates in the vertical direction with a large amplitude during the walking movement of the human backpack, which causes the shoulders of the human body to bear relatively strong impact force. question
