[0005] To achieve the above-mentioned purpose, the utility model discloses a buffering and decompression shoulder strap, comprising: a shoulder strap body, a first filling cavity is arranged inside the shoulder strap body, the first filling cavity is arranged at the position where the shoulder strap body contacts the human shoulder or is arranged inside the entire shoulder strap body, and the first filling cavity is filled with buffering and decompression particles.
[0006] Preferably, a decompression shoulder pad for reducing shoulder pressure is further provided at the position where the shoulder strap body contacts the human shoulder.
[0007] Preferably, a second filling cavity is provided inside the decompression shoulder pad, and the second filling cavity is filled with buffering decompression particles.
[0008] Preferably, the buffering decompression particles are supercritical foaming particles.
[0009] Preferably, the decompression shoulder pad is integrally arranged with the shoulder strap body or detachably mounted on the shoulder strap body.
[0010] Preferably, the first filling cavity is divided into a plurality of filling units, and each filling unit contains buffering decompression particles.
[0011] Preferably, the packing density of the buffering and decompression particles is ≥80%.
[0012] A backpack comprises a bag body and a shoulder strap body. The bag body is provided with a storage space for storing articles, and the bag body is fixedly connected with the shoulder strap body.
[0013] Preferably, a buffer pad is provided on one side of the bag body close to the back.
[0014] Preferably, the buffer pad is filled with buffering and decompression particles.
[0015] The utility model has the following beneficial effects:
[0016] 1. The utility model uses buffering and decompression particles to fill the shoulder strap. The buffering particles have good elasticity, and the gaps between the buffering particles are not easy to be compacted, so that the shoulder strap has good buffering effect and support, thereby absorbing shock and reducing pressure.
[0017] 2. A cushion pad is provided on the bag body to make the bag body fit more closely to the back and improve the cushioning and decompression capacity of the bag body. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0030] Embodiment 1
[0031] like Figure 1 As shown, the utility model provides a buffering and decompression shoulder strap, comprising: a shoulder strap body 100, a first filling cavity 101 is arranged inside the shoulder strap body 100, the first filling cavity 101 is arranged at the position where the shoulder strap body 100 contacts the human shoulder, and the first filling cavity 101 is filled with buffering and decompression particles 110.
[0032] In this embodiment, the buffer decompression particles 110 are supercritical foaming particles, which are composed of countless closed foaming particles, and the gas is wrapped inside. The closed structure of the foaming particles prevents the backpack strap from being compacted after being under pressure, and maintains its buffer decompression effect. At the same time, the buffer decompression particles 110 filled in the shoulder strap can move according to the structure of the shoulder, keep the shape of the shoulder, realize the adaptive function, and strengthen the fit between the backpack strap and the shoulder. Filling the buffer decompression particles 110 only at the shoulder position can also achieve the effect of saving costs and reducing the weight of the backpack.
[0033] Embodiment 2
[0034] like Figure 2 As shown, the difference between this embodiment and the first embodiment is that the first filling cavity 101 is set inside the entire shoulder strap body 100. In this embodiment, the entire shoulder strap body 100 is filled with supercritical foaming particles, so that the weight is evenly distributed on the entire backpack strap, effectively reducing the concentrated pressure on specific parts and improving the comfort of carrying. And because the entire shoulder strap body is filled, the overall structure of the backpack strap is more stable, not easy to deform or twist, and the durability of the backpack is enhanced. Finally, after the entire shoulder strap body 100 is filled, the appearance is more unified and coordinated, giving people a sense of high quality.
[0035] Embodiment 3
[0036] like Figure 3As shown, the difference between this embodiment and the first embodiment is that the first filling cavity 101 is divided into a plurality of filling units 1001, each of which contains buffering decompression particles. In this embodiment, the filling density of the buffering decompression particles is ≥ 80%. By arranging a plurality of filling units 1001 on the strap body 100 and filling them with buffering decompression particles 110, the pressure of the backpack on the shoulders and back can be dispersed more finely. The movement and adjustment of the buffering decompression particles 110 in the filling unit 1001 can automatically adapt to the user's body shape and carrying posture, providing a better carrying experience and comfort.
[0037] Embodiment 4
[0038] like Figures 4 and 5 As shown, the difference between this embodiment and the first embodiment is that a decompression shoulder pad 200 for reducing shoulder pressure is also provided on the strap body 100. In this embodiment, the decompression shoulder pad 200 is detachably mounted on the strap body 100. A second filling cavity is provided inside the decompression shoulder pad 200. The second filling cavity is filled with buffering decompression particles 110. The buffering decompression particles 110 also use supercritical foaming particles, so that the part of the decompression shoulder pad 200 in contact with the shoulder can fit the shoulder to achieve a better buffering and decompression effect. In addition, the provision of the decompression shoulder pad 200 can increase the contact area between the strap body 100 and the shoulder, thereby reducing the pressure of the strap on the shoulder. And because the decompression shoulder pad 200 is detachable, the user can easily remove it for cleaning or replacement to keep the backpack clean and hygienic. The detachable decompression shoulder pad 200 design also allows the user to make personalized adjustments according to their needs and preferences. For example, you can choose whether to use the decompression shoulder pad 200, or adjust the position and angle of the decompression shoulder pad 200 according to the weight of the backpack, the carrying time, and the individual's body shape and comfort preference. In other embodiments, the decompression shoulder pad 200 is not filled with buffer decompression particles 110.
[0039] Embodiment 5
[0040] like Figure 6 As shown, the difference between this embodiment and the first embodiment is that the decompression shoulder pad 200 is integrally arranged with the shoulder strap body 100. In this embodiment, the decompression shoulder pad 200 is the portion of the shoulder strap body 100 where the shoulder strap body 100 is widened at the human shoulder, which increases the contact area between the shoulder strap body 100 and the human shoulder, reduces the pressure of the shoulder strap body 100 on the shoulder, and improves the comfort of the shoulder strap body 100 when in use.
[0041] Embodiment 6
[0042] like Figures 7-9As shown, the difference between this embodiment and the first embodiment is that: a backpack includes a bag body 300 and a shoulder strap body 100, wherein a storage space 320 for storing articles is provided in the bag body 300, and the shoulder strap body 100 is fixedly connected to the bag body 300. In this embodiment, a buffer pad 310 is provided on the side of the bag body 300 close to the back, and the buffer pad 310 is filled with buffer decompression particles 110, and the buffer particles are supercritical foaming particles, so that the bag body 300 can fit the back of the person more closely, and the bag body 300 has a good buffer decompression effect.
[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
