[0030] 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.

[0031] Embodiment 1

[0032] like Figure 1 , Figures 4 to 6 , Figures 8-10 As shown, the utility model provides a cushioning backpack with a spacer fabric 100 structure, comprising: a shoulder strap 200 and a bag body 300, wherein the shoulder strap 200 is fixedly connected to a side of the bag body 300 close to the back of a human body, and the portion of the shoulder strap 200 close to the shoulder of a human body is made of the spacer fabric 100, and the spacer fabric 100 comprises a plurality of pulling units, wherein the pulling units comprise an upper surface layer 110, a lower surface layer 130, and a pulling component 120 connected between the upper surface layer 110 and the lower surface layer 130, and the spacer fabric 100 is filled with cushioning shock absorbing particles 210. The pulling component 120 may be a woven thread, which may penetrate the upper surface layer 110 and the lower surface layer 130, so that it may be a woven thread connected between the upper surface layer 110 and the lower surface layer 130 in the form of a suture, or it may not penetrate the upper surface layer 110 and the lower surface layer 130, and may be connected between the upper surface layer 110 and the lower surface layer 130 through a plurality of pulling components. The pulling arrangement of the pulling component 120 between the upper surface layer 110 and the lower surface layer 130 may be continuous and regular, or discontinuous and irregular.

[0033] In this embodiment, when the shoulder strap 200 is made directly from the spacer fabric 100, it is necessary to seal or hem the edges of the shoulder strap 200 to prevent the filled buffering and shock absorbing particles 210 from falling out. The buffering and shock absorbing particles 210 filled in the spacer fabric 100 are restricted by the fixed space formed by the upper surface, the lower surface and the pulling component 120, which can prevent the buffering and shock absorbing particles 210 from being piled up. The buffering and shock absorbing particles 210 can be evenly distributed in the shoulder strap 200.

[0034] The cushioning and shock-absorbing particles 210 are supercritical foaming particles. In this embodiment, the supercritical foaming particles are composed of countless closed foaming particles with gas wrapped inside. The closed structure of the foaming particles prevents the backpack strap from being compacted after being under pressure, thereby maintaining its cushioning and decompression effect.

[0035] A decompression shoulder pad 220 is provided on the shoulder strap 200 near the human shoulder, and the decompression shoulder pad 220 is detachably connected to the shoulder strap 200. In this embodiment, the decompression shoulder pad 220 is made of a spacer fabric 100, and the decompression shoulder pad 220 is filled with buffering and shock-absorbing particles 210. Supercritical foaming particles have excellent elasticity and buffering properties, and can play an effective buffering role when the shoulder is under pressure, thereby reducing the discomfort of the shoulder. The filling of supercritical foaming particles makes the decompression shoulder pad 220 softer and fits the human body curve, and can better adapt to the shoulder shape of different people, providing a more comfortable use experience. And due to the special structure of supercritical foaming particles and spacer fabric 100, the interior of the decompression shoulder pad 220 has better air permeability and perspiration, which can effectively reduce the dampness and stuffiness of the shoulder and keep it dry and comfortable.

[0036] Embodiment 2

[0037] like Figure 2~3 As shown, the difference between this embodiment and the first embodiment is that the shoulder strap 200 is made entirely of spacer fabric 100. In this embodiment, the spacer fabric 100 can provide good air permeability for the shoulder strap 200, thereby preventing the shoulder from feeling stuffy and damp due to long-term carrying.

[0038] Embodiment 3

[0039] The difference between this embodiment and the first embodiment is that the spacer fabric 100 is coated with a decorative layer. The upper surface layer 110 of each pulling unit is integrally formed as an upper fixed surface, and the lower surface layer 120 of each pulling unit is integrally formed as a lower fixed surface, and both the upper fixed surface and the lower fixed surface are connected to the inner wall of the decorative layer. In this embodiment, the decorative layer is made of cloth, which is wrapped around the outside of the spacer fabric 100 and can protect the spacer fabric 100.

[0040] Embodiment 4

[0041] like Fig. 9 As shown, the difference between this embodiment and the first embodiment is that a shock-absorbing cushion 310 is provided on the side of the bag body 300 close to the back of the human body, and the shock-absorbing cushion 310 is provided with a curved surface close to the back of the human body that fits the curve of the back of the human body. In this embodiment, the design of the shock-absorbing cushion 310 fitting the back of the human body can make the backpack better disperse the weight, reduce the pressure on the back and shoulders, and improve the comfort of carrying. At the same time, the design of the shock-absorbing cushion 310 fitting the back of the human body can also reduce the shaking of the backpack during walking, making the backpack more stable and further improving the comfort.

[0042] The shock-absorbing cushion 310 is made of a spacer fabric 100, and the shock-absorbing cushion 310 is filled with buffering and shock-absorbing particles 210. In this embodiment, the combination of the spacer fabric 100 and the supercritical foaming particles enables the backpack to achieve a lightweight design while maintaining the buffering performance. This helps to reduce the overall weight of the backpack and improve the comfort of carrying. The structure of the spacer fabric 100 makes the back of the backpack have good air permeability, which helps to reduce the accumulation of sweat and improve the comfort of the back. In addition, a ventilation groove 311 is provided on the side of the shock-absorbing cushion 310 close to the back of the human body, so that the air permeability of the back of the backpack is better.

[0043] Embodiment 5

[0044] like Figure 7 As shown, the difference between this embodiment and the first embodiment is that the pressure relief shoulder pad 220 and the shoulder strap 200 are integrated. In this embodiment, the integrated design allows the pressure relief shoulder pad 220 to be tightly combined with the shoulder strap 200, which can more effectively disperse the weight of the backpack and reduce the pressure on the shoulders and back. This design helps to reduce shoulder and neck fatigue and discomfort caused by carrying a backpack for a long time, and improves the overall comfort of the user.

[0045] 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.
