[0040] Please refer to Figure 1 、 Figure 2 and Figure 3 ,and Figure 3 and Figure 4, a second part 13 is formed with a first opening 130. A third part 14 is movably connected to the second part 13. The third part 14 covers the first opening 130 and jointly encloses an accommodation space 11 with the first part 12 and the second part 13; a photovoltaic module 20 is provided on a side of the third part 14 facing away from the accommodation space 11; an isolation structure 30 is disposed in the accommodation space 11, and the isolation structure 30 is detachably connected to the first part 12 or the second part 13. The isolation structure 30 is configured to divide the accommodation space 11 into a plurality of sub-spaces 110.

[0041] In the backpack 100 according to the embodiment of the present utility model, by providing the isolation structure 30 in the accommodation space 11 of the backpack 100, the accommodation space 11 can be divided into a plurality of sub-spaces 110, so that different types of items can be stored in different sub-spaces 110 respectively. This helps to reduce the mutual interference between items and is conducive to the classified storage of items, thereby improving the orderliness inside the backpack 100 and facilitating the user to find specific types of items.

[0042] In addition, the photovoltaic module 20 can convert solar energy into electrical energy, enabling the backpack 100 to achieve self-sufficiency in energy and provide electrical energy for other devices. Moreover, the isolation structure 30 divides the accommodation space 11 into a plurality of sub-spaces 110, which can form a frame structure, thereby enhancing the overall structural stability of the backpack 100, so that the photovoltaic module 20 can remain stable during the use of the backpack 100.

[0043] Specifically, the main body part 10 is the main contour shape part of the backpack 100, and the accommodation space 11 of the main body part 10 is used for loading items. The main body part 10 can be made of materials such as nylon, canvas or leather. The first part 12 is the part for fitting with the user's body. The angle between the first part 12 and the second part 13 can be set according to requirements, for example, it can be 45°, 60°, 75°, 90°, 120°, etc. Herein, the angle refers to the smaller angle in the space angle formed by the two parts.

[0044] The second part 13 can be used to connect the first part 12 and the third part 14. The second part 13 and the first part 12 can be integrally formed. The second part 13 can include a first connecting part and a second connecting part. The first connecting part can be fixed to the third part 14, and the second connecting part can be connected to the third part 14 through connecting pieces such as a zipper or a buckle, so that the second part 13 and the third part 14 can be separated or connected, thereby realizing the movable connection between the third part 14 and the second part 13.

[0045] The first opening 130 can be a passage for the user to place or take out items. When the user needs to take out the items placed in the accommodation space 11, the third part 14 can be separated from the second part 13 to open the first opening 130. After the user takes out the items in the accommodation space 11, the third part 14 can be connected to the second part 13 so that the third part 14 covers the first opening 130.

[0046] The photovoltaic module 20 is a module for converting solar energy into electrical energy. The photovoltaic module 20 can include monocrystalline silicon, polycrystalline silicon or thin-film solar cells, and includes a fixing part. The battery part of the photovoltaic module 20 is used for photoelectric conversion, and the fixing part of the photovoltaic module 20 is used for connecting to the outer surface of the main body part 10. The photovoltaic module 20 can be arranged in any area of the outer surface of the main body part 10. In order to enable the photovoltaic module 20 to have a better illumination angle, the illumination component can be arranged on the side of the main body part 10 facing the sun, or on the side of the main body part 10 away from the user's body when the backpack 100 is carried on the back. The photovoltaic module 20 can be flexible to adapt to the shape of the main body part 10.

[0047] The photovoltaic module 20 can be arranged on the third part 14 by means of adhesion, stitching, or fixing with a zipper or Velcro, etc. For example, the fixing part of the photovoltaic module 20 can be stitched to the third part 14. The battery part of the photovoltaic module 20 can be adhered to the third part 14.

[0048] The isolation structure 30 can be a partition 31 or a mesh, etc. The isolation structure 30 can be detachably connected only to the first part 12; it can also be detachably connected only to the second part 13; it can also be detachably connected to both the first part 12 and the second part 13. The connection between the isolation structure 30 and the second part 13 can be a direct connection or an indirect connection.

[0049] The detachable connection between the isolation structure 30 and the first part 12 or the second part 13 can be achieved by means of Velcro or a buckle, etc. For example, a first Velcro including a fuzzy surface can be arranged on the first part 12, and a second Velcro including a hook surface can be arranged on the isolation structure 30, so that the fuzzy surface and the hook surface are combined to realize the connection between the first part 12 and the isolation structure 30, and the fuzzy surface and the hook surface are separated to realize the disassembly of the first part 12 and the isolation structure 30. By using the Velcro method, the first part 12 and the isolation structure 30 can be quickly separated, thereby improving the disassembly and assembly efficiency between the first part 12 and the isolation structure 30.

[0050] For another example, a first hook-and-loop fastener including a fuzzy surface may be provided on the second part 13, and a second hook-and-loop fastener including a hook surface may be provided on the isolation structure 30. The fuzzy surface and the hook surface are combined to realize the connection between the second part 13 and the isolation structure 30. The fuzzy surface and the hook surface are separated to realize the disassembly of the second part 13 and the isolation structure 30. By using the hook-and-loop fastener, the second part 13 and the isolation structure 30 can be quickly separated, thereby improving the disassembly and assembly efficiency between the second part 13 and the isolation structure 30.

[0051] The isolation structure 30 can divide the accommodation space 11 into multiple sub-spaces 110. The multiple sub-spaces 110 may have multiple sub-openings, and the orientations of the multiple sub-openings may be the same as the orientation of the first opening 130. The shapes and volumes of the multiple sub-spaces 110 may be the same or different. The multiple sub-spaces 110 can be used to store different types of items. For example, medical items, thermal insulation supplies, drinking water, food, or other types of items can be stored in different sub-spaces 110 respectively.

[0052] Please refer to Figure 3 and Figure 5 , in some embodiments, the isolation structure 30 includes a partition 31. The partition 31 includes a first end 310 and a second end 311 that are angularly connected. The first end 310 is detachably connected to the first part 12, and the second end 311 is detachably connected to the second part 13.

[0053] In this way, the partition 31 can effectively isolate the different sub-spaces 110 and reduce the probability of interference between the items stored in the sub-spaces 110. The two ends of the partition 31 are respectively connected to the first part 12 and the second part 13, which can improve the stability of the partition 31 during use and prevent the partition 31 from shifting due to factors such as loading heavy objects or the movement of the backpack 100.

[0054] Specifically, the partition 31 can be made of a rigid material or a flexible material to meet different isolation requirements. For example, the partition 31 can be made of polycarbonate. The partition 31 can be a flat plate, a curved plate with a certain curvature, or a plate of other shapes. The cross-sectional shape of the partition 31 can be a regular shape, such as a square, a rectangle, a semi-circle, etc. The first end 310 and the second end 311 are two connected ends on the partition 31. For example, if the partition 31 is square, the first end 310 and the second end 311 can be two connected sides of the square and the areas around the sides.

[0055] The connection between the first end 310 and the first part 12 can be achieved by means of a hook-and-loop fastener or a buckle, etc. For example, two groove portions are provided on the first end 310 of the partition 31, and two protruding portions are provided on the first part 12. The grooves and the protrusions cooperate with each other to realize the detachable connection between the first end 310 and the first part 12.

[0056] The second end portion 311 and the first portion 12 can also be connected by means of Velcro or snap fasteners, etc. For example, two groove portions are provided on the second end portion 311 of the partition 31, and two protruding portions are provided on the first portion 12. The grooves and the protrusions cooperate with each other to achieve the detachable connection between the second end portion 311 and the first portion 12.

[0057] In one embodiment, the partition 31 can be a foldable board. The partition 31 can be of a symmetric structure and can be folded in half along its own axis of symmetry or along other axial directions. In this way, the partition 31 can be flexibly arranged according to requirements.

[0058] Please refer to Figure 5 、 Figure 6 and Figure 7 In some embodiments, the isolation structure 30 includes a partition 31 and a peripheral board 32. The partition 31 includes a first end portion 310 and a second end portion 311 connected at an angle. The first end portion 310 is detachably connected to the first portion 12. The peripheral board 32 is disposed around the partition 31. The peripheral board 32 includes a first side wall 320 and a second side wall 321 facing away from each other. The first side wall 320 is detachably connected to the second portion 13, and the second side wall 321 is detachably connected to the second end portion 311.

[0059] In this way, the peripheral board 32 can connect the second portion 13 and provide an independent mounting point for the partition 31, thereby improving the stability of the partition 31 during the use of the backpack 100.

[0060] Specifically, the shape of the peripheral board 32 can be the same as the shape of the second portion 13. This can enable the peripheral board 32 to closely adhere to the second portion 13, thereby increasing the size of the space enclosed by the peripheral board 32 and further increasing the sub-space 110. Both the first side wall 320 and the second side wall 321 can include connection structures such as Velcro and snap fasteners for detachably connecting to the second portion 13 and the second end portion 311 of the partition 31. The first side wall 320 and the second side wall 321 can include the same connection structure or different connection structures.

[0061] In one embodiment, the first side wall 320 can include a Velcro with a fuzzy surface, and the second portion 13 can include a Velcro with a hook surface. The two Velcros cooperate with the Velcro on the second portion 13 to achieve the detachable connection between the first side wall 320 and the second portion 13. Two groove portions are provided on the second side wall 321. Two protruding portions are provided on the second end portion 311. The grooves and the protrusions cooperate with each other to achieve the detachable connection between the second end portion 311 and the first portion 12.

[0062] Please refer to Figure 3 and Figure 8, in some embodiments, the partition 31 includes a first partition 312 and a second partition 313 connected to the first partition 312. The numbers of the first partition 312 and the second partition 313 are both plural. The first partition 312 and the second partition 313 are configured to divide the accommodation space 11 into a plurality of sub-spaces 110. The first partition 312 is connected to opposite side walls of the second portion 13. Along the arrangement direction p of the first partition 312, the second partition 313 is connected to two adjacent first partitions 312. The second partition 313 selectively connects to different positions of two adjacent first partitions 312 to change the volume ratio between the sub-spaces 110.

[0063] In this way, the second partition 313 can selectively connect to adjacent first partitions 312 at different positions. This design provides the user with the ability to adjust the sizes of the respective sub-spaces 110 between the first partition 312 and the second partition 313, enabling the backpack 100 to adapt to the storage requirements of items of different sizes and shapes, thereby enhancing the flexibility of use of the backpack 100.

[0064] Specifically, the connection between the first partition 312 and the second partition 313 can be achieved by means such as Velcro, buckles, etc. The number of the first partitions 312 can be two, three, four or even more. The number of the second partitions 313 can be two, three, four or even more. The plurality of first partitions 312 and the plurality of second partitions 313 can intersect pairwise to divide the isolation space into a plurality of sub-spaces 110. The sub-spaces 110 can be jointly enclosed by the first portion 12, the second portion 13, the third portion 14, the first partition 312 and the second partition 313.

[0065] The first partition 312 can extend along the length direction or the width direction of the main body portion 10. The second partition 313 can be connected to different positions of the first partition 312, thereby dividing the space between two adjacent first partitions 312 into a plurality of parts, and these parts are the sub-spaces 110. A plurality of structures such as Velcro or buckles for connecting to the plurality of second partitions 313 can be provided on opposite side surfaces of two adjacent first partitions 312. Two adjacent first partitions 312 can be parallel to each other or arranged at other angles.

[0066] Please refer to Figure 3 and Figure 8, in one embodiment, two adjacent first partitions 312 are parallel to each other, and two adjacent first partitions 312 are both axisymmetric structures and their axes of symmetry are on the same straight line. When the second partition 313 extends along the axis of symmetry and is connected to the middle parts of the two first partitions 312, two sub-spaces 110 with the same volume can be formed in the regions on both sides of the second partition 313; when the second partition 313 extends along the axis of symmetry and is connected to other positions of the two first partitions 312, two sub-spaces 110 with different volumes can be formed in the regions on both sides of the second partition 313.

[0067] Please refer to Figure 3 and Figure 9 , in order to change the volume ratio between the sub-spaces 110, it can also be achieved by increasing or decreasing the number of the second partitions 313, that is, by disassembling and assembling the second partitions 313.

[0068] In some embodiments, the first partition 312 is selectively connected to different positions of the second part 13 to change the volume ratio between the sub-spaces 110.

[0069] In some embodiments, in order to change the volume ratio between the sub-spaces 110, it can also be achieved by increasing or decreasing the number of the first partitions 312, that is, by disassembling and assembling the first partitions 312.

[0070] Please refer to Figure 3 and Figure 10 , in some embodiments, the partition 31 includes a first partition 312 and a second partition 313 connected to the first partition 312. The first partition 312 and the second partition 313 are used to divide the accommodation space 11 into multiple sub-spaces 110.

Along the arrangement direction p of the first partition 312, the second partition 313 is connected to the first partition 312 and the second part 13. The second partition 313 is selectively connected to different positions of the first partition 312 and the second part 13 to change the volume ratio between the sub-spaces 110.

[0071] In this way, the second partition 313 can be selectively connected to the first partition 312 and the second part 13 at different positions. This design provides the user with the ability to adjust the sizes of the sub-spaces 110 between the first partition 312 and the second part 13, enabling the backpack 100 to adapt to the storage requirements of items with different sizes and shapes, thus improving the flexibility of use of the backpack 100.

[0072] Specifically, the second partition 313 can be connected to different positions on the first partition 312 and the second part 13, thereby dividing the space between the first partition 312 and the second part 13 into multiple parts, which are the sub-spaces 110. Multiple structures such as Velcro or buckles for connecting to the multiple second partitions 313 can be provided on both the first partition 312 and the second part 13.

[0077] In some embodiments, the first partition 312 is detachably connected to the second partition 313.

[0078] In this way, when a larger storage space is needed, the user can remove the first partition 312 or the second partition 313 to form one or more larger sub-spaces 110; when fine classification is needed, the first partition 312 and the second partition 313 can be reinstalled to form more sub-spaces 110 for facilitating the placement of more different types of items.

[0079] Specifically, the detachable connection between the first partition 312 and the second partition 313 can be achieved by means of Velcro, snap fasteners, etc.

[0080] In some embodiments, the first partition 312 and the second partition 313 are integrally formed. Among them, the integral forming can adopt processes such as injection molding, blow molding, compression molding or 3D printing.

[0081] In this way, the integrally formed first partition 312 and second partition 313 reduce the splicing steps in the assembly process, simplify the production process, and help improve production efficiency.

[0082] In one embodiment, the second partition 313 can rotate relative to the first partition 312, and the second partition 313 rotates at different angles to change the volume ratio between the sub-spaces 110. After the second partition 313 rotates, the second partition 313 can be connected to the peripheral plate 32 and the first part 12, or connected to the second part 13 and the first part 12; the second partition 313 can also be only connected to the first part 12.

[0083] The angle between the first partition 312 and the second partition 313 can be a right angle, an acute angle or an obtuse angle to meet different needs. Please refer to Figure 3 and Figure 6 , in some embodiments, the first partition 312 and the second partition 313 are perpendicular to each other.

[0084] In this way, the vertically arranged first partition 312 and second partition 313 help to maximize the use of the storage capacity of the backpack 100, so that each sub-space 110 has a certain volume, reducing the sub-spaces 110 with too small volume, especially in the corner and edge areas of the backpack 100, and these spaces can be utilized more fully.

[0085] Please refer to Figure 3 and Figure 4 , in some embodiments, the backpack 100 further includes a covering part 40, and the covering part 40 is arranged closer to the first part 12 than the third part 14; the covering part 40 is detachably connected to at least part of the second part 13, and the covering part 40 covers the first opening 130.

[0086] In this way, by being detachably connected to at least part of the second part 13 and covering the first opening 130, the covering part 40 can provide additional protection for the accommodation space 11 of the backpack 100. It can not only protect the internal items from external influences such as dust, moisture and other potential damages, but also prevent the items stored in the accommodation space 11 from moving and hitting the third part 14 during the use of the backpack 100, resulting in damage to the photovoltaic module 20.

[0087] Specifically, the covering part 40 can be made of fabric, plastic or other materials. The covering part 40 can be in the structure of a plate, a net, etc. The covering part 40 can be arranged between the first part 12 and the third part 14. The covering part 40 can be connected to the peripheral area of the first opening 130. The covering part 40 can be switched between a closed state and an open state. When the covering part 40 is in the closed state, the covering part 40 covers the first opening 130. When the covering part 40 is in the open state, the covering part 40 opens the first opening 130.

[0088] In one embodiment, the covering part 40 can be connected to a part of the second part 13 by sewing and can be connected to another part of the second part 13 in the form of a zipper.

[0089] In another embodiment, the covering part 40 can be connected to the second part 13 in the form of a zipper.

[0090] Please refer to Figure 6 、 Figure 7 and Figure 12 , in some embodiments, the covering part 40 is detachably connected to at least part of the peripheral plate 32. The peripheral plate 32 is formed with a second opening 322, and the size of the second opening 322 is smaller than the size of the first opening 130. The covering part 40 covers the second opening 322.

[0091] In this way, by being detachably connected to at least part of the peripheral plate 32 and covering the second opening 322, the covering part 40 can provide additional protection for the accommodation space 11 of the backpack 100. It can not only protect the internal items from external influences such as dust, moisture and other potential damages, but also prevent the items stored in the accommodation space 11 from hitting the third part 14 during the use of the backpack 100, resulting in damage to the photovoltaic module 20.

[0092] Specifically, the covering part 40 can be connected to the peripheral area of the second opening 322. The covering part 40 can be switched between a closed state and an open state. When the covering part 40 is in the closed state, the covering part 40 covers the second opening 322. When the covering part 40 is in the open state, the covering part 40 opens the second opening 322.

[0093] In one embodiment, the covering part 40 can be connected to a part of the peripheral plate 32 by sewing and can be connected to another part of the peripheral plate 32 in the form of a zipper.

[0094] In another embodiment, the covering part 40 can be connected to the peripheral plate 32 in the form of a zipper.

[0095] Please refer to Figure 12, in some embodiments, the backpack 100 may further include an interlayer 50, which may be disposed between the covering portion 40 and the third portion 14. The provision of the interlayer 50 facilitates the classified storage of items, thereby improving the orderliness inside the backpack 100 and making it convenient for the user to find specific types of items. Moreover, since the interlayer 50 is disposed between the covering portion 40 and the third portion 14, the third portion 14 and the covering portion 40 can cooperate to support the interlayer 50, thereby maintaining the stability of the items stored in the interlayer 50.
