1. TECHNICAL FIELD

The invention relates to the technical field of backpack, in particular to a two-way adjustable shock-absorbing backpack.

2. BACKGROUND ART

Backpack is a tool used to carry items in daily life, which can store items together for easy portability, and double shoulder braces can help people carry more easily, backpack is a necessary tool in daily life, which is not only simple in structure, and easy to operate.

When people hike, travel, commute or perform sports training with backpacks, people's walking basically likes an inverted pendulum, and the backpack follows the human body to reciprocate up and down in the vertical direction. In the prior art, the braces of the backpack are all fixed, and there is no room for buffering, people wear the backpack for a long time, the braces are pressed and tightened under the human body for a long time, which is easy to cause shoulder strain, and the fit between the braces and the back of the human body is soft and cannot form support, resulting in discomfort.

In order to reduce the force exerted on the shoulder by the up-and-down motion of the backpack during the human body's movement, in the invention with publication number of CN215125225U, a shoulder strap independent shock-absorbing backpack is disclosed, wherein a covering cloth is arranged on one side of a strap, an S-shaped reinforcing strip is arranged in the covering cloth, rigid connection at the joint is changed into elastic connection through a first elastic band and a second elastic band, the weight of two shoulder straps can be distributed in a balanced manner when the backpack is carried on the back, and the effects of damping and reducing load are achieved when the backpack is used, the telescopic length of the second elastic band is limited through the rigid limiting band, the second elastic band is prevented from exceeding the elastic limit, the durability of the second elastic band is guaranteed, the rigid limiting band4slides along the first limiting groove, the shoulder strap is prevented from swinging left and right, the strap slides along the second limiting groove, the stability is further improved, and the back of the human body is more fitted through the S-shaped reinforcing strip, and the supporting force of the back panel is increased, thereby conforming to ergonomics and being more comfortable. The two shoulder straps are respectively provided with an independent elastic body, and the lengths of the two shoulder straps can be automatically adjusted according to the use conditions such as stooping and leaning to one side, thereby the two straps are always wrapped on the shoulders and cannot slip off.

However, although the shock-absorbing backpack can reduce the force exerted by the backpack on the shoulders of the human body to a certain extent through the elastic belt, the shock-absorbing backpack cannot adjust the degree of shock absorption, when the quality of the bag changes, or when the movement range of the person changes, the vertical amplitude of the backpack cannot be actively adjusted, and can only be adjusted passively by the elasticity of the elastic belt, thereby the shock absorption effect will be greatly reduced, and greatly reducing the comfort of the backpack.

In addition, in the process of using the above shock-absorbing backpack, the back is not supported, which is easy to cause the backpack to bend and not fit the back when worn, the force of the backpack is not vertical, which is easy to collide with the buttocks or waist of the bearer, and the vertical shock absorption effect is reduced, which makes the backpack uncomfortable and affects the use experience.
