[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] As mentioned in the background section of this application, research has found that existing multi-purpose knapsack conversion methods have certain drawbacks, including complex steps, non-standardized operation sequence of feature points, limited number of compatible connectors, low conversion efficiency, and poor ease of operation.

[0021] To address the aforementioned shortcomings, this application discloses a conversion method for multi-purpose backpacks, which is more standardized, highly adaptable, and easy to operate compared to traditional conversion methods.

[0022] The following will describe in detail, with reference to the accompanying drawings, how the solution of this application solves the above-mentioned technical problems.

[0023] Example 1: Please see Figure 1 and Figure 2 In this embodiment of the invention, a multi-purpose backpack includes: a carrying body, which is formed by multiple plate-shaped structural components connected sequentially by flexible connecting parts. The multiple plate-shaped structural components include a first side panel 4, a front panel 6, a second side panel 5, a back panel 1, a top panel 2, and a bottom panel 3. The carrying body has a shelf state and a closed state: in the closed state, the multiple plate-shaped structural components are connected to each other by detachable connecting parts to jointly enclose and form an accommodating space; in the shelf state, the first side panel 4 and the back panel 1 are separated, and the top panel 2 and the bottom panel 3 are separated from any three of the first side panel 4, the front panel 6, the second side panel 5, and the back panel 1, respectively. The carrying body is formed by the first side panel 4, the front panel 6, the second side panel 5, the back panel 1, the top panel 2, and the bottom panel 3 connected by flexible connecting parts to form an integral structure. The flexible connecting parts enable relative rotation and folding of each plate-shaped structural component. In the closed state, each plate-shaped structural component encloses the accommodating space for storing items. In the shelf state, the plate-shaped structural components separate and unfold to achieve hanging storage. The detachable connecting parts enable switching control between the shelf state and the closed state.

[0024] In this embodiment, the detachable connector is connected in a three-section independent connection, such as... Figure 3 and Figure 4 As shown, the structure includes a longitudinal connection between side panel 4 and back panel 1, a first transverse connection between bottom panel 3 and side panel 4, panel 6, and side panel 5, and a second transverse connection between top panel 2 and side panel 4, panel 6, and side panel 5. More specifically, in the first segment, the side of side panel 4 is connected to the side of back panel 1 via connectors from top to bottom or bottom to top; in the second segment, bottom panel 3 is connected to the bottom of side panel 4, panel 6, and side panel 5 via connectors from left to right or right to left; in the third segment, top panel 2 is connected to the top of side panel 4, panel 6, and side panel 5 via connectors from left to right or right to left. This three-section independent connection allows each connection point to open and close independently to accommodate different folding angles.

[0025] In this embodiment, multiple plate-shaped structural members have a first hardness and a first support, while the flexible connecting part has a second hardness lower than the first hardness, allowing the multiple plate-shaped structural members to rotate relative to each other. The first hardness and first support of the plate-shaped structural members ensure the structural stability and load-bearing capacity of side plate 4, front panel 6, side plate 5, back plate 1, top plate 2, and bottom plate 3. The lower second hardness of the flexible connecting part allows each plate-shaped structural member to rotate freely relative to each other, completing the folding and unfolding separation actions.

[0026] In this embodiment, the shelf configuration is selected from at least one of the following arrangements: top plate 2 and bottom plate 3 are respectively connected to the upper and lower parts of back plate 1; top plate 2 and bottom plate 3 are respectively connected to the upper and lower parts of panel 6; top plate 2 is connected above back plate 1, and bottom plate 3 is connected below panel 6. In this embodiment, top plate 2 and bottom plate 3 are respectively connected to the upper and lower parts of back plate 1. Multiple connection configurations of top plate 2, bottom plate 3 with back plate 1 and panel 6 enhance the structural flexibility of the shelf configuration, adapting to different hanging scenarios and installation requirements.

[0027] In this embodiment, at least one hook 8 is provided on at least one of the plurality of plate-shaped structural members, and the hook 8 is located outside the support body in the closed state. The hook 8 enables the support body to be suspended and fixed in the shelf state, ensuring the stability of the items being placed, and the hook 8 being located outside in the closed state does not affect the normal carrying of the backpack or shoulder bag.

[0028] In this embodiment, at least one of the multiple plate-shaped structural members has at least one storage bag 7 on its outer and inner sides. The storage bags 7 on the inner and outer sides of the plate-shaped structural members increase the overall storage capacity, realize the classification and placement of items, and adapt to the storage needs of items of different sizes and types.

[0029] In this embodiment, as Figure 11 , Figure 12 and Figure 13 As shown, the closed states include backpack and shoulder bag states. In backpack state, a pair of shoulder straps 9 are provided on the outer side of the back panel 1 or panel 6. Both the outer sides of the back panel 1 and panel 6 have openings 10, and the openings 10 are connected to the back panel 1 and panel 6 by connectors. In shoulder bag state, a shoulder strap 11 is provided on the outer side of the carrying body. In backpack state, the shoulder straps 9 enable convenient carrying over both shoulders, and the openings 10 facilitate quick access to and placement of items in the storage space. In shoulder bag state, the shoulder strap 11 enables convenient carrying over one shoulder. The two states expand the usage scenarios and carrying methods of the device.

[0030] In this embodiment, when closed, the inner storage space is used to store adult products, while the outer storage bag 7 is used to store infant and toddler products. With the inner storage space for adult products and the outer storage bag 7 for infant and toddler products when closed, this separates and organizes parent-child items, preventing clutter and improving the targeted use of these items.

[0031] In this embodiment, the connector includes any one of zippers, snaps, and Velcro. Zippers, snaps, and Velcro connectors enable quick opening and closing and secure connection with detachable attachments, adapting to different usage frequencies and structural assembly requirements, thus improving ease of operation and connection reliability.

[0032] This application also discloses a method for converting a multi-purpose backpack, which has a shelf state and a closed state. The conversion method includes the following steps: when converting the shelf state to the closed state, the connection between feature points A, B, C, and D is closed by three separable connectors; when converting the closed state to the shelf state, the connection between feature points A, B, C, and D is separated by three separable connectors.

[0033] In this embodiment, when there are three separable connectors, the closing sequence of the feature points corresponding to the first connector includes: B→C or C→B; the closing sequence of the feature points corresponding to the second connector includes: A→B or B→A; and the closing sequence of the feature points corresponding to the third connector includes: C→D or D→C.

[0034] In this embodiment, when converting the shelf state to the closed state, the connecting pieces between the top plate 2 and the top of side plate 4 and side plate 5 are closed, and the connecting pieces between the bottom plate 3 and the bottom of side plate 4 and side plate 5 are closed. The sides of side plate 4 and back plate 1 are then rotated and folded together to form an internal storage space. When converting the closed state to the shelf state, the connecting pieces between the top plate 2 and the top of side plate 4 and side plate 5 are disconnected, and the connecting pieces between the bottom plate 3 and the bottom of side plate 4 and side plate 5 are disconnected. Each plate is then unfolded and attached to an object using hooks 8. By closing the connecting pieces between the top plate 2, bottom plate 3, and side plates 4 and 5, and folding side plate 4 and back plate 1, the storage space is quickly enclosed, completing the conversion from the shelf state to the closed state. By disconnecting the connecting pieces, unfolding the plate-like structural members, and attaching them using hooks 8, the conversion from the closed state to the shelf state is quickly completed, achieving a rapid dual-state switching without item transfer and preventing items from being missed.

[0035] Example 2: The difference between this embodiment and embodiment one is that: when the shelf state is converted to the closed state, the connection between feature points A, B, C, and D is closed by two separable connectors; when the closed state is converted to the shelf state, the connection between feature points A, B, C, and D is separated by two separable connectors.

[0036] In this embodiment, when there are two detachable connectors, the closing sequence of the feature points corresponding to the first connector includes: A→B→C; the closing sequence of the feature points corresponding to the second connector includes: C→D or D→C. More specifically, the detachable connectors are connected in a two-stage manner, such as... Figure 5 and Figure 6As shown, in the first section, the bottom plate 3 is connected to the bottom of the side plate 4, the bottom of the panel 6, and the bottom of the side plate 5 from left to right by connectors. At the same time, the side of the side plate 4 is connected to the side of the back plate 1 from bottom to top by connectors, and the bottom connector and the side connector are combined into one connector. In the second section, the top plate 2 is connected to the top of the side plate 4, the top of the panel 6, and the top of the side plate 5 from left to right or from right to left by connectors.

[0037] Example 3: The difference between this embodiment and embodiment one is that: when the shelf state is converted to the closed state, the connection between feature points A, B, C, and D is closed by two separable connectors; when the closed state is converted to the shelf state, the connection between feature points A, B, C, and D is separated by two separable connectors.

[0038] In this embodiment, when there are two detachable connectors, the closing sequence of the feature points corresponding to the first connector includes: D→C→B; the closing sequence of the feature points corresponding to the second connector includes: A→B or B→A. More specifically, the detachable connectors are connected in a two-stage manner, such as... Figure 7 and Figure 8 As shown, in the first segment, the top plate 2 is connected to the top of the side plate 4, the top of the panel 6, and the top of the side plate 5 from left to right by connectors. At the same time, the side of the side plate 4 is connected to the side of the back plate 1 from top to bottom by connectors, and the top connector and the side connector are combined into one connector. In the second segment, the bottom plate 3 is connected to the bottom of the side plate 4, the bottom of the panel 6, and the bottom of the side plate 5 from left to right or from right to left by connectors.

[0039] Example 4: The difference between this embodiment and embodiment one is that: when the shelf state is converted to the closed state, the connection between feature points A, B, C, and D is closed by a separable connector; when the closed state is converted to the shelf state, the connection between feature points A, B, C, and D is separated by a separable connector.

[0040] In this embodiment, when there is only one detachable connector, the closing sequence of each feature point includes: D→C→B→A. More specifically, the detachable connector adopts a single-segment integrated connection, such as... Figure 9 As shown, the top plate 2 is connected to the top of the side plate 4, the top of the panel 6, and the top of the side plate 5 from left to right by connectors. The side of the side plate 4 is connected to the side of the back plate 1 from top to bottom by connectors. The bottom plate 3 is connected to the bottom of the side plate 4, the bottom of the panel 6, and the bottom of the side plate 5 from right to left by connectors. The top connector, the side connector, and the bottom connector are combined into a continuous connector.

[0041] Example 5: The difference between this embodiment and embodiment one is that: when the shelf state is converted to the closed state, the connection between feature points A, B, C, and D is closed by a separable connector; when the closed state is converted to the shelf state, the connection between feature points A, B, C, and D is separated by a separable connector.

[0042] In this embodiment, when the separable connector is a single unit, the closing sequence of the feature points includes: A→B→C→D. More specifically, the separable connector adopts a single-segment integrated connection, such as... Figure 10 As shown, the bottom plate 3 is connected to the bottom of the first side plate 4, the bottom of the panel 6, and the bottom of the second side plate 5 from left to right by connectors. The side of the first side plate 4 is connected to the side of the back plate 1 from bottom to top by connectors.
