[0002] Backpacks, as an extremely convenient carrying tool, have always played a vital role in people's daily lives. Whether it's students carrying schoolbags to school, office workers carrying work documents and computers, or travelers loading various items on a journey, backpacks have become indispensable partners with their excellent storage and portability. However, traditional backpacks often expose some problems when carried for long periods of time. Due to the close contact between the backpack and the back, the back is prone to sweating under constant pressure and friction. Sweat will gradually accumulate in the small space between the backpack and the back, which will not only make people feel extremely uncomfortable physically, but the feeling of dampness and stuffiness will continue to bother the wearer.

[0003] Chinese utility model patent announcement number CN219422402U discloses a sweat-absorbent and breathable backpack. The backpack is provided with a protective pad on the backpack. The back of the protective pad has a first adhesive sheet and a second adhesive sheet. The protective pad can be removed from the backpack body. The protective pad is provided with a breathable layer, an antibacterial layer and a sweat-absorbent layer. It can absorb sweat when the backpack body is used. The protective pad can be directly removed when washing, which is more convenient to clean. It effectively solves the problem of cleaning the backpack as a whole. It is easy to use, and the overall device structure is simple and practical. However, when the user wears the sweat-absorbent and breathable backpack, the backpack body is in close contact with the user's back. In hot weather, the heat dissipation effect of the back is poor, sweating is easy, and the amount of sweating cannot be reduced. The functionality is insufficient. Summary of the Invention

[0033] The side support assembly 4 includes a mounting seat 401 and a side support rod 402, and the center of the mounting seat 401 is fixedly connected to the side support rod 402; the top support assembly 5 includes a mounting seat 501 and a top support rod 502, and the center of the mounting seat 501 is fixedly connected to the top support rod 502.

[0034] Specifically, the back panel 2 is made of polycarbonate, and three identical fixing seats 3 are provided. Advantageously, the back panel 2 is made of polycarbonate, which has high strength, high toughness, and good impact resistance, providing sufficient support for the fixing seats 3. When the fixing seats 3 are subjected to force, the back panel 2 is not easily deformed, and the back panel 2 is not easily collapsed when the backpack body 1 is filled with a large number of items, thereby maintaining structural stability.

[0035] Specifically, the side support assembly 4 is provided with two identical side support rods 402 made of 316 stainless steel and having a curved structure. The advantage is that the side support rods 402 and the top support rod 502 are both curved structures, cooperating with the frame 8 to form a flexible support structure. When the user wears the shoulder straps 10 and carries the backpack body 1 on their back, the mesh surface 7 contacts the back, and the side support rods 402 and the top support rod 502 are stressed, so that a certain gap is maintained between the back panel 2 of the backpack body 1 and the user's back, improving ventilation. In hot weather, the heat from the user's back dissipates through the mesh surface 7, preventing sweating after prolonged close contact with the backpack body 1. The mesh fabric 11 and ventilation holes 12 of the shoulder straps 10 improve the breathability of the area where the shoulder straps 10 contact the user, preventing sweating and providing high comfort.

[0036] Example 2: Figure 2-5 As shown, it is an improvement to the previous embodiment.

[0037] Specifically, groove 302 is adapted to mounting base 1 401, which has the same structure as mounting base 2 501.

During use, when the user wears the shoulder strap 10 and carries the backpack body 1 on the back, the mesh surface 7 contacts the back, and the side support rods 402 and the top support rod 502 are stressed, so that the back plate 2 of the backpack body 1 maintains a certain gap with the user's back, thereby improving the ventilation effect. In hot weather, the heat on the user's back is reduced. The air is dispersed from the mesh surface 7 to avoid sweating after being in close contact with the backpack body 1 for a long time. The mesh 11 and the ventilation holes 12 of the shoulder straps 10 improve the air permeability of the area where the shoulder straps 10 contact the user, preventing sweating and providing high comfort. The cushioning cloth bag 6 is made of polyester fiber cloth wrapped with sponge, which has good cushioning performance. After the backpack body 1 is carried on the back, the bottom of the backpack body 1 is often in close contact with the user's back under the action of its own gravity and the shoulder straps 10. The cushioning cloth bag 6 can reduce the pressure of the backpack on the human back. The anti-slip pad 9 is made of silicone rubber, which has good anti-slip performance and can prevent the backpack from sliding during use.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
