[0036] In order to more clearly illustrate the technical solution of the embodiment of the utility model, the utility model will be described in detail with reference to the accompanying drawings.

[0037] Example 1

[0038] The multifunctional schoolbag 5 described in this embodiment has a multifunctional board 1 integrally formed on the surface of the schoolbag 5, and the multifunctional board includes:

[0039] A hardboard 101 completely covers the fixed surface integrally formed with the school bag 5. The hardboard 101 can be made of a high-strength, lightweight composite material, such as glass fiber reinforced plastic or carbon fiber composite material. This material has excellent strength and rigidity and can withstand large loads without deformation or cracking. It also has good weather resistance and can resist changes in humidity and temperature, so that the school bag 5 can maintain its function and shape under various environmental conditions. The hardboard 101 needs to have a certain hardness to support heavy objects, for example, when it is used as a temporary small table or small chair. In addition, the surface of the hardboard 101 can be coated with an anti-slip coating to prevent items from slipping.

[0040] Articulated rod group 2, for specific structure, refer to Figure 1 The two ends of the hard board 101 are connected to the hinge rod group 2, and the two ends of the hard board 101 have a first hinge rod 102, the first hinge rod 102 is hinged with a first hinge sleeve 201, the first hinge sleeve extends a transition strip 202, and the end of the transition strip 202 has a second hinge rod 203, and the first hinge rod 102 is axially parallel to the second hinge rod 203.

[0041] When in the adjustment state, first unlock the first hinge rod 102, then the hard board 101 can be rotated around the first hinge rod 102 to a desired position, and then the first hinge rod 102 is locked. If the angle of the hard board 101 needs to be adjusted, the second hinge rod 203 can be unlocked, then the hard board 101 can be rotated around the second hinge rod 203 to a desired angle, and then the second hinge rod 203 is locked. This hinge relationship design makes the multifunctional school bag 5 more flexible to use and can adapt to various usage scenarios.

[0042] The supporting leg 3 has a second hinge sleeve 301 , and the second hinge sleeve 301 is hinged to the second hinge rod 203 .

[0043] For more details, please refer to Figure 2-4 First, the supporting leg 3 is rotated to form a certain angle with the transition bar 202, and then the transition bar 202 is rotated to rotate the hinge rod group 2 as a whole to the state where the supporting leg 3 supports the school bag 5. At this time, the school bag 5 can be used as a small table or a small chair. Figure 2-4 The structures shown in the figure are all school bags 5 with two hard plates, and the details will be described in Example 2.

[0044] When using, the user needs to rotate the supporting leg 3 so that the transition bar 202 forms a certain angle. This angle needs to be adjusted according to the specific needs of the user. For example, if the user wants to use the school bag 5 as a small table, a larger angle may be required; if the user wants to use the school bag 5 as a small chair, a smaller angle may be required. Then, the user needs to rotate the transition bar 202 so that the hinged rod group 2 rotates as a whole to the state where the supporting leg 3 supports the school bag 5. At this time, the hard board 101 surface of the school bag 5 can be used as the desktop of a small table or the seat of a small chair.

[0045] In a preferred embodiment, in order to stably fix the angle of the supporting leg 3 and the transition bar 202, the hinged part is provided with a damping member or a gear adjustment part. The damping member can provide a certain resistance to prevent the supporting leg 3 and the transition bar 202 from rotating freely when subjected to external force. The gear adjustment part can fix the supporting leg 3 and the transition bar 202 at a specific angle. For example, when the user rotates the supporting leg 3 and the transition bar 202 to the desired angle, the supporting leg 3 and the transition bar 202 can be fixed at this angle by operating the gear adjustment part. This design can ensure that when the user uses the school bag 5 as a small table or a small chair, the school bag 5 can be stably supported and will not tilt or slide due to the action of external forces.

[0046] In some specific embodiments, the transition bar 202 can rotate with the first hinge rod 102 as the axis to an extreme position close to the hard board 101. In this extreme position, the plane of the transition bar 202 facing the hard board is parallel to or completely in contact with the hard board surface. This design allows the legs 3 to fit tightly with the hard board when the backpack 5 is carried, without causing discomfort to the user's back. At the same time, this also makes the backpack 5 more compact, making it easier for the user to carry it.

[0047] In combination with the above-mentioned structure, it can be known that the first articulated sleeve 201 is looped on the first articulated rod 102. When the first articulated sleeve 201 rotates with the first articulated rod 102 as the axis, the rotational freedom of the first articulated sleeve 201 is limited by the swing amplitude of the transition bar 202; when the transition bar 202 rotates to the contact position with the hard board, the rotation of the first articulated sleeve 201 in this direction is limited; when the transition bar 202 rotates to contact the side of the backpack 5, the rotation of the first articulated sleeve 201 in this direction is limited.

[0048] In order to prevent the ring from falling off, the applicant provides that in some embodiments, both ends of the second articulated sleeve 301 have large ends with a diameter larger than the rest of the rod body, and the second articulated sleeve 301 is looped on the second articulated rod.

The two multifunctional panels 1 are fixed to the backpack 5 respectively. The backpack 5 is provided with a fixed zipper 8 at the fixed gap between the two hard panels 101. The specific structure can be referred to Figure 5 The multifunctional panels 1 are an important part of the school bag 5. They not only provide support to keep the school bag 5 in shape, but also serve as a support surface for a small table or a small chair. The connection between the multifunctional panels 1 and the school bag 5 can be fixed or detachable, depending on the design requirements. The fixed zipper 8 is used to close the opening of the school bag 5 to protect the items in the school bag 5.

[0052] When the backpack 5 is unfolded into a planar structure, it includes a rectangular portion 501 which forms the side of the backpack 5 after rolling up and is a rectangular surface after unfolding, a fixed rectangle 502 extending from the long side of the rectangle, and the fixed rectangle 502 is connected to the rolled-up rectangular portion 501 after folding to form the cavity of the backpack 5. The rectangular portion 501 has a pair of male buckles 801 and female buckles that match each other with a symmetry axis. The male buckle 801 and the female buckle constitute the fixed zipper 8. The specific structure can be referred to Figure 6 This design allows the backpack 5 to be unfolded into a flat surface when needed, for example, when the user needs a larger workspace. At the same time, the design of the male buckle 801 and the female buckle allows the shape of the backpack 5 to be adjusted as needed.

[0053] Specifically, when using, the user first needs to unfold the school bag 5 to form a planar structure. Then, the user can roll up the rectangular part 501 as needed to form the side of the school bag 5. In this process, the fixed rectangle 502 will be connected with the rolled-up rectangular part 501 to form the cavity of the school bag 5. Then, the user can pull up the fixed zipper 8 and close the opening of the school bag 5 by operating the male buckle 801 and the female buckle. When a small table or a small chair is needed, the user can rotate the multi-function board 1 to the desired angle and fix it by the damping member or the gear adjustment part. In this way, the school bag 5 can be transformed into a small table or a small chair, providing a convenient work or rest space for the user.

[0054] As mentioned above, the unfolded school bag 5 can be used as a carpet. In order to make the unfolded school bag 5 have a larger area, in a preferred embodiment, the folded state can refer to Figure 6 It is understood that the male buckle 801 and the female buckle are located in the middle area of ​​the rectangular part 501.
