[0027] To further understand the features, technical means, specific purposes and functions achieved by the present utility model, the present utility model will be further described in detail below in conjunction with the drawings and specific implementation modes.

[0028] Refer to Figures 1 - 6 As shown, the present utility model provides a multifunctional backpack with octopus multi-directional distributed buffering, including a schoolbag body 1. The schoolbag body 1 is usually made of durable materials such as nylon or polyester fiber to withstand daily wear and tear and weight. A stationery storage cavity 11 is provided at a position near the top on one side of the schoolbag body 1. The stationery storage cavity 11 is designed specifically for storing stationery such as pens, notebooks, rulers, etc. A raincoat storage cavity 12 is provided at a position near the bottom of the schoolbag body 1 on one side of the schoolbag body 1. A first buffer component 14 for buffering is provided on one side of the schoolbag body 1 away from the stationery storage cavity 11. A second buffer component 15 is further provided on the outer side of the first buffer component 14. The second buffer component 15 is connected to the schoolbag body 1.

[0029] The first buffer component 14 includes a hard cloth 141 provided at the central position of the schoolbag body 1. An elastic band 142 is provided around the hard cloth 141. One end of the elastic band 142 is connected to the schoolbag body 1. The cross-section of the hard cloth 141 is a regular octagon. Eight elastic bands 142 are provided and are respectively connected to the respective sides of the regular octagon. One end of each elastic band 142 is connected to the schoolbag body 1. A limit band 143 is further connected to each side of the hard cloth 141. One end of the limit band 143 is connected to the schoolbag body 1. The length of the limit band 143 is greater than the length of the elastic band 142. The elastic band 142 enhances the buffering effect and provides additional energy absorption capacity. The elastic band 142 not only helps to fix the position of the hard cloth 141, but also further disperses and absorbs energy when impacted.

[0030] The second buffer component 15 includes a buffer cotton back pad 151 for buffering. The buffer cotton back pad 151 is connected to the schoolbag body 1 to reduce the pressure of the schoolbag body 1 on the user's back. The buffer cotton back pad 151 is usually made of high-density foam, memory foam or other soft and elastic materials. These materials have excellent compressibility and recoverability, can deform under pressure to absorb energy, and quickly return to the original shape after the pressure is released. This characteristic enables the buffer cotton back pad 151 to effectively disperse the weight of the schoolbag body 1 and evenly distribute it on the user's back, thereby reducing local pressure points.

[0031] The first buffer component 14 is specifically composed of a regular octagon-shaped hard cloth 141. Elastic bands 142 are connected to each side of the hard cloth 141, and the other ends of the elastic bands 142 are connected to the schoolbag body 1. When the user carries the schoolbag body 1 on the back, the elastic bands 142 can play a buffering role in all directions of up, down, left, and right, thereby effectively reducing the pressure on the shoulders. In addition, a buffer cotton back pad 151 is also provided on the schoolbag body 1 to further reduce the pressure on the user's back.

[0032] A raincoat storage cavity 12 is internally provided with a detachable raincoat component 18 for shielding the schoolbag body 1 and the user from rain on rainy days. When in use, the raincoat component 18 can be taken out from the raincoat storage cavity 12 and worn on the user. When not in use, the raincoat component 18 can be folded into the raincoat storage cavity 12. The raincoat storage cavity 12 and the raincoat component 18 are disassembled or installed through a zipper.

[0033] The raincoat component 18 is connected to the schoolbag body 1 through a zipper to achieve detachable connection. On rainy days, the user can take out the raincoat component 18 from the raincoat storage cavity 12 for rain shielding; when not in use, the raincoat component 18 can be conveniently stored in the raincoat storage cavity 12. The detachable design of the zipper also facilitates removing the raincoat component 18 for cleaning.

[0034] A backpack strap system 17 is also provided at a position of the schoolbag body 1 far from the stationery storage cavity 11. The backpack strap system 17 includes two main backpack straps 171 and secondary backpack straps 172. One end of the main backpack strap 171 is connected with a male buckle 1711, and one end of the secondary backpack strap 172 is connected with a female buckle 1721. The male buckle 1711 is inserted into the female buckle 1721 to connect the main backpack strap 171 and the secondary backpack strap 172 together. The backpack strap system 17 includes four support frames 173 installed on the schoolbag body 1. Two support frames 173 are fixed at the top of the schoolbag body 1, and the other two support frames 173 are fixed at the bottom of the schoolbag body 1. A chute 1731 and a limit groove 1732 are also provided on the support frames 173. Each support frame 173 corresponds to the main backpack strap 171 and the secondary backpack strap 172. The other ends of the main backpack strap 171 and the secondary backpack strap 172 are connected with limit blocks, and the limit blocks are inserted into the support frames 173 and slide in the chute 1731. The two main backpack straps 171 pass through the chute 1731 in the support frames 173 at the top of the schoolbag body 1, and the two secondary backpack straps 172 pass through the chute 1731 in the support frames 173 at the bottom of the schoolbag body 1.

[0035] Both the main backpack strap 171 and the secondary backpack strap 172 can move in the support frames 173, so as to be flexibly adjusted according to the shoulder width of the user, ensuring the comfort and convenience of use.

[0036] A handle 16 is also provided at the top of the schoolbag body 1, and a side storage cavity 13 is provided on the side of the schoolbag body 1.

[0037] Working principle: When in use, by moving the main strap 171 and the secondary strap 172, the main strap 171 and the secondary strap 172 are adjusted to appropriate positions. The male buckle 1711 is inserted into the female buckle 1721 to connect the main strap 171 and the secondary strap 172 together. On one side of the schoolbag body 1, a first buffer component 14 is provided. The first buffer component 14 is composed of a regular octagon-shaped hard cloth 141. Elastic bands 142 are connected to each side of the hard cloth 141, and the other ends of the elastic bands 142 are firmly connected to the schoolbag body 1. When the user wears the schoolbag body 1 on the back, these elastic bands 142 can provide effective buffering in all directions of up, down, left, and right, thus significantly reducing the pressure on the user's shoulders. In addition, the schoolbag body 1 is also provided with a buffer cotton back pad 151, which further enhances the back support and effectively reduces the pressure on the user's back. On rainy days, the user can conveniently take out the raincoat component 18 from the raincoat storage cavity 12 to block the rain. When not in use, the raincoat component 18 can be easily stored in the raincoat storage cavity 12. The raincoat component 18 and the schoolbag body 1 are detachably connected by a zipper. This design not only facilitates the access and storage of the raincoat component 18 but also facilitates the cleaning and maintenance of the raincoat component 18.

[0038] The above embodiments only represent one or several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
