[0037] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0038] like Figure 1 and Figure 11 As shown in the illustration, this embodiment presents a flexible protective backpack, which mainly includes a backpack body 1, a detachable pouch 2, and a set of buckle components for connecting the two. The backpack body 1 is equipped with a conventional shoulder strap system, including a left shoulder strap 3 and a right shoulder strap 4. The buckle components are respectively installed on the shoulder straps of the backpack body 1 and the pouch 2, allowing the pouch 2 to be detachably fixed to the shoulder straps and flexibly positioned in a location convenient for monitoring and retrieving items, such as in front of the user's chest or waist.

[0039] Specifically, in this solution, the backpack body 1 serves as the base of the entire system, and its basic structure includes the bag body that houses the main compartment, the carrying system, etc. The improvement in this solution focuses on its carrying system, especially the shoulder straps.

[0040] The left shoulder strap 3 and right shoulder strap 4 are made of wide, thick, and elastic webbing, and can be filled with soft padding to improve carrying comfort. The upper ends of the two shoulder straps connect to the upper edge of the backpack, and the lower ends connect to the bottom of the backpack or the waist support area, forming a stable double-shoulder carrying structure.

[0041] To facilitate connection with the small bag 2, at least two fixing buckles are installed on each shoulder strap, such as... Figure 2 As shown, specifically:

[0042] Secure the upper buckle 5 of the left shoulder strap 3 in the upper area (usually located near or slightly below the user's collarbone); secure the lower buckle 6 of the left shoulder strap 3 in the lower area (usually located near the user's shoulder blade or armpit).

[0043] At the corresponding positions on the right shoulder strap 4, the upper buckle 7 and the lower buckle 8 of the right shoulder strap are fixedly installed in a mirror manner.

[0044] The upper and lower fasteners utilize a standard snap-on 14 structure. They are securely attached to the shoulder strap webbing via stitching, riveting, or heat pressing. The orientation of these snap-on 14 structures is ergonomically designed to ensure that the webbing of the small bag 2, once connected, follows a natural direction, is not easily twisted, and allows for easy one-handed fastening and unfastening by the user.

[0045] like Figure 3 and Figure 4 As shown, specifically, in this solution, the small bag 2 is the core functional module of the system, and its design must consider both connection with the backpack, independent use, and anti-theft requirements. The opening of the small bag 2 is located on the front and adopts a hidden zipper 15 design. That is, the zipper 15 teeth are covered by a layer of fabric extending from the bag body, and the zipper 15 head cannot be directly accessed from the outside. This design can effectively prevent it from being easily opened in crowded places, significantly enhancing anti-theft performance. The zipper 15 head can be designed to be small in size and can be connected to a pull tab for easy gripping.

[0046] More specifically, the small bag 2 has a first webbing 9 and a second webbing 10 on each side. A first webbing end buckle 11 is provided at the end of the first webbing 9; and a second webbing end buckle 12 is provided at the end of the second webbing 10. These two buckles use a slot structure that matches the buckles on the backpack shoulder straps. They have an internal locking mechanism corresponding to the male buckle tongue, ensuring that the connection will not accidentally come undone.

[0047] In addition, a webbing adjustment buckle 13 is provided on the first webbing 9 and the second webbing 10 respectively. By pulling the webbing through the adjustment buckle 13, the effective length of the two webbing extending from the bag body can be adjusted steplessly. Thus, when the small bag 2 is connected to the backpack or used independently, its hanging position and fit can be adjusted to adapt to the height, body shape and usage habits of different users.

[0048] Furthermore, to facilitate the use of the small bag 2 independently as a crossbody bag or waist bag after detaching it from the main backpack, it is equipped with an independent buckle 14. This buckle 14 typically consists of a male buckle and a female buckle, with the male buckle located on the first webbing 9 and the female buckle located on the second webbing 10. When the small bag 2 is used independently, the ends of the two webbing straps can be connected together through this separate buckle 14 to form a closed carrying loop.

[0049] The aforementioned left shoulder strap upper buckle 5, left shoulder strap lower buckle 6, right shoulder strap upper buckle 7, right shoulder strap lower buckle 8, first webbing end buckle 11, and second webbing end buckle 12 together constitute a buckle system. All the buckles use standardized male and female buckles, ensuring that any female buckle can reliably and quickly engage and disengage with any male buckle. This multi-point to multi-point free connection capability is the foundation for supporting various subsequent carrying modes.

[0050] The flexibility of this invention is mainly reflected in the diverse connection methods between the small bag 2 and the backpack body 1. Users can choose one or more of the following methods to combine and use, depending on security needs, retrieval habits, activity scenarios, and even clothing coordination. For example:

[0051] Mode 1: Upright carrying mode

[0052] This mode is designed to vertically position the small bag 2 on one side of the chest, which is the most intuitive and stable connection method, and facilitates quick access to items on one side.

[0053] like Figure 5 As shown, for the left-chest upright carrying method: First, align and fasten the first webbing buckle 11 on the back of the small bag 2 with the buckle 5 on the left shoulder strap of the backpack; then, align and fasten the second webbing buckle 12 on the back of the small bag 2 with the buckle 6 on the left shoulder strap of the backpack. After fastening, the small bag 2 will hang naturally in front of the user's left chest. By adjusting the adjusting buckles 13 on the two webbing straps, the height and tilt angle of the small bag 2 can be changed so that its upper edge is approximately below the collarbone, making it easier to look down and retrieve items, while avoiding interference when the arm swings.

[0054] like Figure 6 As shown, for right-chest upright carrying: First, fasten the first webbing end buckle 11 on the back of the small bag 2 to the buckle 7 on the right shoulder strap of the backpack; then, fasten the second webbing end buckle 12 on the back of the small bag 2 to the buckle 8 on the right shoulder strap of the backpack; the small bag 2 is then fixed in front of the right chest, and the adjustment method is the same as above.

[0055] The upright carrying design keeps the small bag 2 close to the body, significantly reducing the risk of theft from the side or back. The buckles can be quickly removed with one hand (e.g., when going through security), and then quickly put back in place, balancing security and convenience.

[0056] Mode 2: Crossbody carrying mode

[0057] This mode places the small bag 2 diagonally across the front of the torso, which better secures the small bag 2 in the center of the body, providing stronger protection and a more balanced weight distribution.

[0058] like Figure 7 As shown, the diagonal sling method (left-top-right-bottom): First, fasten the first webbing end buckle 11 on the back of the small bag 2 to the buckle 5 on the left shoulder strap of the backpack; then, fasten the second webbing end buckle 12 on the back of the small bag 2 to the buckle 8 on the right shoulder strap of the backpack; after connecting, the small bag 2 is tilted from the upper left to the lower right, slung horizontally above the abdomen. This position is the most natural, and the small bag 2 is completely within the user's line of sight and the protection of their arms.

[0059] like Figure 8 As shown, the right-upper-left-lower diagonal carrying method is as follows: First, fasten the first webbing end buckle 11 on the back of the small bag 2 to the buckle 7 on the right shoulder strap of the backpack; then, fasten the second webbing end buckle 12 on the back of the small bag 2 to the buckle 6 on the left shoulder strap of the backpack; the small bag 2 is tilted from the upper right to the lower left, and the effect is mirror-symmetrical to the left-upper-right-lower diagonal carrying method.

[0060] The crossbody style is one of the best ways to carry a bag for security. The small bag is securely locked in the center of the front of the body, making it extremely difficult to cut the webbing or forcibly remove. At the same time, this connection method distributes the weight of the shoulder straps, potentially making it more comfortable to carry for extended periods.

[0061] Mode 3: Horizontal carrying mode

[0062] This mode positions the small bag 2 horizontally at a higher or lower position in front of the chest, providing different style options and a different retrieval experience.

[0063] like Figure 9 As shown, the top horizontal carrying method is as follows: First, fasten the first webbing end buckle 11 on the back of the small bag 2 to the buckle 5 on the left shoulder strap of the backpack; then, fasten the second webbing end buckle 12 on the back of the small bag 2 to the buckle 7 on the right shoulder strap of the backpack; after connection, the small bag 2 hangs horizontally on the user's upper chest, in a high position, close to the neck.

[0064] like Figure 10 As shown, the lower horizontal carrying method is as follows: First, fasten the buckle 11 at the end of the first webbing on the back of the small bag 2 to the buckle 6 at the bottom of the left shoulder strap of the backpack; then, fasten the buckle 12 at the end of the second webbing on the back of the small bag 2 to the buckle 8 at the bottom of the right shoulder strap of the backpack; after connecting, the small bag 2 hangs horizontally on the abdomen or waist. This position is relatively concealed and does not hinder the large range of upper body movements, making it suitable for outdoor sports such as cycling and hiking.

[0065] The horizontal carrying design offers more personalized positioning options. Users can flexibly choose whether to hang the small bag 2 high or low, depending on the opening position of their jacket, their personal retrieval habits, or the type of activity they are doing that day, achieving true customization of carrying.

[0066] Mode 4: Small Package 2 Independent Use Mode

[0067] When users do not need to carry a large-capacity backpack, or enter places where they do not need to carry a large bag (such as shopping malls, restaurants, or conference rooms), they can completely detach the small bag from the backpack and convert it into an independent carry-on bag.

[0068] To convert it into a crossbody bag: First, wrap the first webbing 9 or the second webbing 10 around your shoulder and then around your waist, so that the small bag 2 is placed on your back. Pull the first webbing 9 and the second webbing 10 so that the male and female buckles meet at your chest and are then inserted to secure the first webbing 9 and the second webbing 10. Then, adjust the total length of the circular shoulder strap to a suitable length for crossbody use by adjusting the buckle 13. Finally, adjust the small bag 2 to the front of your chest, and you can use the small bag 2 as a crossbody bag.

[0069] To convert to a waist bag: First, wrap the first webbing 9 and the second webbing 10 around the waist so that the small bag 2 is placed on the back. Pull the first webbing 9 and the second webbing 10 so that the male and female buckles meet at the chest and are then inserted to secure the first webbing 9 and the second webbing 10. Then, adjust the total length of the circular shoulder strap to a suitable length for crossbody wear by adjusting the buckle 13 so that it can be tightly wrapped around the waist. Finally, adjust the small bag 2 to the front of the chest.

[0070] This design fully unlocks the functionality of the small bag 2, freeing it from dependence on a backpack. Users no longer need to carry an extra bag specifically for storing valuables, achieving multiple uses with one bag and greatly enhancing the product's practical value and user engagement.

[0071] In summary, the connection system based on standard buckles allows for the connection and separation of the small bag 2 and the backpack to be completed within seconds, without the need for tools. A clear "click" indicates locking, and pressing the release button on the buckle easily releases the bag, providing an intuitive and user-friendly experience. A sophisticated modular buckle system integrates the traditional backpack with the portable small bag 2, while allowing for easy separation. It's not simply about binding two bags together; rather, through standardized interfaces and multi-point connection design, it allows for various scientific carrying modes such as vertical, diagonal, and horizontal carrying, fundamentally solving the user pain point of needing both large-capacity storage and the security and convenience of the small bag 2. Its simple structure, controllable cost, high reliability, and lack of need to change the user's existing backpack usage habits make it easily acceptable to the market. The independent function of the small bag 2 further enhances the product's added value. In conclusion, this utility model is an innovative backpack design that combines high practicality, significant anti-theft capabilities, excellent flexibility, and good comfort, possessing promising market prospects and promotional value.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
