specific Embodiment approach

[0034] Specifically, please also refer to Figure 4 , Figure 5 and Figure 6 , as a specific embodiment of the backpack provided by the present invention, the linear slide rail assembly 51 includes two guide rails 511 extending in the vertical direction and sliders 512 respectively slidingly fitted with the two guide rails 511, and the two guide rails 511 are arranged side by side. And be arranged on the backboard 2 at intervals, two sliders 512 are fixedly connected with the mobile bracket 3 respectively, and the number of the guide rails 511 and the sliders 512 is two, and the two guide rails 511 are arranged side by side on the backboard 2, and the sliders 512 is slidingly matched with the guide rail 511. The two guide rails 511 extend vertically and are parallel to each other, and are respectively arranged on both sides of the backboard 2, so that when the bag body 1 shakes up and down, it is easier to balance it and prevent the slider 512 from being stuck in the slider...

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...
