[0035] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown in, the backpack 100 of the embodiment of the present utility model includes a main body portion 10, a photovoltaic module 20, an interface assembly 30, an energy storage device 40 and an opening / closing portion 50. The main body portion 10 has a receiving space 11, and the receiving space 11 is provided with an opening 110; the photovoltaic module 20 is connected to the main body portion 10 and is located outside the receiving space 11; the interface assembly 30 is connected to the main body portion 10 and is located outside the receiving space 11; the energy storage device 40 is electrically connected to both the photovoltaic module 20 and the interface assembly 30; the opening / closing portion 50 is connected to the main body portion 10, and the opening / closing portion 50 can be switched between a first state and a second state.

[0036] In the backpack 100 according to the embodiment of the present utility model, the accommodation space 11 of the main body 10 can be used to accommodate the energy storage device 40 when the main body 10 is in the second state, so as to protect the energy storage device 40 from external environmental factors. The opening and closing part 50 changes the positional relationship with the opening 110 by switching states, and can realize the rapid access to the energy storage device 40, so as to facilitate the use or replacement of the energy storage device 40. The photovoltaic module 20 can provide electric energy and output it through the energy storage device 40 and the interface component 30. Since the interface component 30 is located outside the accommodation space 11. Therefore, an external device can be directly connected to the interface component 30, so as to realize functions such as convenient charging and data transmission.

[0037] Specifically, the main body 10 is the main contour part of the backpack 100. The main body 10 can be used to load items and provide an installation or placement platform for the photovoltaic module 20, the interface component 30, the energy storage device 40, the opening and closing part 50 and other structures. The accommodation space 11 is a space located inside the main body 10, and the accommodation space 11 can be surrounded by the inner surface of the main body 10. The opening 110 is the entrance of the accommodation space 11 for accessing items. The shape of the opening 110 can be a regular shape such as a square or a circle, or an irregular shape. The number of the openings 110 can be one or multiple. Multiple openings 110 can serve as channels for multiple energy storage devices 40 to enter, so as to realize the access to multiple energy storage devices 40.

[0038] The photovoltaic module 20 is a module for converting solar energy into electric energy. The photovoltaic module 20 can include monocrystalline silicon, polycrystalline silicon or thin-film solar cells, and includes a fixing part. Among them, the battery part of the photovoltaic module 20 is used for photoelectric conversion, and the fixing part of the photovoltaic module 20 is connected to the main body 10. The photovoltaic module 20 can be flexible to adapt to the shape of the main body 10.

[0039] The photovoltaic module 20 can be connected to the main body 10 in a non-detachable manner such as adhesion or stitching, or in a detachable manner such as snap connection, using a zipper or Velcro fixation. For example, the fixing part of the photovoltaic module 20 can be stitched to the main body 10. The battery part of the photovoltaic module 20 can be adhered to the main body 10.

[0040] The number of the photovoltaic modules 20 can be multiple. Multiple photovoltaic modules 20 can provide more electric energy, and multiple photovoltaic modules 20 can be arranged at intervals on the main body 10. For example, the number of the photovoltaic modules 20 is four, and the four photovoltaic modules 20 are spaced apart from each other and arranged in a rectangular array on the main body 10.

[0041] The interface component 30 is a component for implementing power transmission and data exchange. External devices (such as smartphones, tablets, or other devices) can be charged by connecting to the interface component 30. External devices can also transmit audio signals, files, or communicate with other devices by connecting to the interface component 30. For example, the interface component 30 can be a USB (Universal Serial Bus) interface, and USB can provide functions of charging and data transmission.

[0042] The interface component 30 can be connected to the main body 10 in a non-detachable manner such as by adhesion or stitching, or in a detachable manner such as by snap connection, using a zipper or Velcro fixation. For example, the interface component 30 can include a Velcro with a fuzzy surface, and the main body 10 can include a Velcro with a hook surface, so that the fuzzy surface and the hook surface are combined to realize the connection between the interface component 30 and the main body 10, and the fuzzy surface and the hook surface are separated to realize the disassembly of the interface component 30 and the main body 10. The number of interface components 30 can be one or multiple. Multiple interface components 30 can provide functions of power transmission and data exchange for multiple external devices simultaneously.

[0043] The energy storage device 40 is a device for storing the electric energy output by the photovoltaic module 20. The energy storage device 40 can be a lithium battery, a supercapacitor, etc. Electrical connections can be achieved between the energy storage device 40 and the photovoltaic module 20, and between the energy storage device 40 and the interface component 30 through the cable 60.

[0044] The photovoltaic module 20, the energy storage device 40, and the interface component 30 can be connected in sequence. When the photovoltaic module 20 is exposed to sunlight, the photovoltaic module 20 converts light energy into direct current electric energy by using the photovoltaic effect. The direct current electric energy generated by the photovoltaic module 20 is first transmitted to the energy storage device 40. The energy storage device 40 can store the received electric energy for use when needed. The energy storage device 40 can provide electric energy for the interface component 30. When an external device is connected to the interface component 30, the interface component 30 can provide functions such as charging and data transmission.

[0045] The opening and closing part 50 is a component for opening or closing the opening 110. The opening and closing part 50 can be driven to switch from the first state to the second state, or from the second state to the first state. In the second state, the outer surface of the opening and closing part 50 can be flush with the outer surface of the main body part 10. A part of the opening and closing part 50 can be connected to the main body part 10, such as by adhesion, sewing, snap connection, using a zipper or Velcro. Another part of the opening and closing part 50 can move relative to the main body part 10. The opening and closing part 50 is driven away from the main body part 10, so as to separate from the opening 110, and the opening and closing part 50 is driven close to the main body part 10, so as to close the opening 110. For example, the user pulls or rotates the opening and closing part 50 by hand, so that the opening and closing part 50 is close to or away from the main body part 10, so as to open or close the opening 110. As Figure 3 shown, the opening and closing part 50 can rotate in the direction shown by t.

[0046] Among them, components such as Velcro or a zipper can be provided on the opening and closing part 50. Corresponding Velcro or a zipper can be provided on the periphery of the opening 110, so as to separate the opening part 110 from the opening 110 and to close the opening 110 by the opening part 110.

[0047] Please refer to Figure 1 , in some embodiments, the main body part 10 includes a first side part 12 and a second side part 13, the first side part 12 and the second side part 13 are angularly connected, the photovoltaic module 20 is arranged on the first side part 12, and the interface component 30 is arranged on the second side part 13.

[0048] In this way, by arranging the photovoltaic module 20 on the first side part 12 of the backpack 100 and arranging the interface component 30 on the second side part 13, this optimizes the space layout of the backpack 100, which is not only convenient for using the interface component 30, but also convenient for arranging a larger area of the photovoltaic module 20 on the first side part 12, thereby improving the space utilization rate.

[0049] Specifically, the first side part 12 and the second side part 13 can be connected by a non-detachable connection method such as adhesion or sewing. The first side part 12 and the second side part 13 can also be connected by a detachable method such as snap connection, using a zipper or Velcro.

[0050] The outer surface area of the first side part 12 can be larger than the outer surface area of the second side part 13. This can provide a larger space to facilitate the layout of the photovoltaic module 20. The first side part 12 can be the side part with the largest outer surface area on the main body part 10. This can provide a larger space to facilitate the layout of the photovoltaic module 20. The angle between the first side part 12 and the second side part 13 can be an acute angle, a right angle or an obtuse angle.

[0051] In other embodiments, the photovoltaic module 20 and the interface module 30 may also be disposed on the same side. For example, the photovoltaic module 20 and the interface module 30 may both be disposed on the first side 12. This is beneficial to reducing the use of the cable 60 between the photovoltaic module 20 and the interface module 30, thereby reducing the manufacturing cost.

[0052] Please refer to Figure 1 、 Figure 2 and Figure 3 , in some embodiments, the first side 12 is provided with an opening 110. The first side 12 includes a first region 120 and a second region 121. Along the vertical direction H, the first region 120 is located above the second region 121. The opening and closing part 50 is fixed to the second region 121 and forms a first fixing part 51. The first fixing part 51 extends along the width direction W of the main body part 10. The opening and closing part 50 is detachably connected to the first region 120 and is driven to rotate around the first fixing part 51 to open or close the opening 110, so as to realize the switching of the opening and closing part 50 between the first state and the second state.

[0053] In this way, the user can open or close the opening 110 of the accommodation space 11 through a simple rotating operation. This simplifies the opening and closing process, enabling the user to quickly access the energy storage device 40. Due to the detachable connection between the opening and closing part 50 and the first region 120, the user can quickly open or close the opening 110 of the accommodation space 11 as needed.

[0054] Specifically, the first region 120 and the second region 121 may be two functional regions on the first side 12. The first fixing part 51 may be a part formed by sewing, gluing, etc. between the opening and closing part 50 and the second region 121. The first fixing part 51 may serve as the rotation axis of the opening and closing part 50.

[0055] The detachable connection between the opening and closing part 50 and the first region 120 may be achieved by snap connection, using a zipper or Velcro. For example, the opening and closing part 50 may include Velcro with a fuzzy surface, and the first region 120 may include Velcro with a hook surface. When the user needs to open the opening 110, the user can tear off the two Velcros and make the opening and closing part 50 rotate around the first fixing part 51. Different rotation angles of the opening and closing part 50 relative to the first fixing part 51 can make the opening 110 have different exposure degrees. As the rotation angle of the opening and closing part 50 relative to the first fixing part 51 continuously increases, the exposure degree of the opening 110 also continuously increases until the opening 110 is completely exposed. When the user needs to close the opening 110, the user can rotate the opening 110 part in the opposite direction around the first fixing part 51 until the opening and closing part 50 rotates to a position close to the opening 110, and then make the two Velcros composite to realize the closing of the opening 110.

[0056] It should be noted that in Figure 1In [the figure], the regions illustrated by the first region 120 and the second region 121 are only examples for convenient understanding and shall not be construed as a limitation to this embodiment.

[0057] Please refer to Figure 4 , in some embodiments, the second side portion 13 is provided with an opening 110. The second side portion 13 includes a third region 130 and a fourth region 131. Along the vertical direction H, the third region 130 is located above the fourth region 131. The opening and closing portion 50 is fixed to the fourth region 131 and forms a second fixing portion 52. The second fixing portion 52 extends along the thickness direction of the main body portion 10. The opening and closing portion 50 is detachably connected to the third region 130 and is driven to rotate around the second fixing portion 52 to open or close the opening 110, thereby realizing the switching of the opening and closing portion 50 between the first state and the second state.

[0058] Thus, since the photovoltaic module 20 is disposed on the first side portion 12, it is convenient to provide a larger area of the photovoltaic module 20 on the first side portion 12 by providing the opening 110 on the second side portion 13. The user can open or close the opening 110 of the accommodation space 11 through a simple rotation operation. This simplifies the opening and closing process, enabling the user to quickly access the energy storage device 40. Due to the detachable connection between the opening and closing portion 50 and the third region 130, the user can quickly open or close the opening 110 of the accommodation space 11 as needed.

[0059] Specifically, the third region 130 and the fourth region 131 may be two functional regions on the second side portion 13. The second fixing portion 52 may be a portion formed by sewing, bonding, etc. between the opening and closing portion 50 and the fourth region 131. The second fixing portion 52 may serve as the rotation axis of the opening and closing portion 50.

[0060] The detachable connection between the opening and closing portion 50 and the third region 130 may be achieved by snap connection, using a zipper or a magic tape. For example, the opening and closing portion 50 may be provided with a first zipper, and the third region 130 may be provided with a second zipper. When it is necessary to open the opening 110, the user can unzip the first zipper and the second zipper and rotate the opening and closing portion 50 around the second fixing portion 52. Rotating the opening and closing portion 50 by different angles relative to the second fixing portion 52 can result in different degrees of exposure of the opening 110. As the angle of rotation of the opening and closing portion 50 relative to the second fixing portion 52 continuously increases, the degree of exposure of the opening 110 also continuously increases until the opening 110 is completely exposed. When it is necessary to close the opening 110, the user can rotate the opening and closing portion 50 in the opposite direction around the second fixing portion 52 until the opening and closing portion 50 rotates to a position close to the opening 110, and then connect the first zipper and the second zipper to close the opening 110.

[0061] It should be noted that in Figure 4In the figure, the areas indicated by the third area 130 and the fourth area 131 are merely examples for easy understanding and cannot be used as a limitation to this embodiment.

[0062] See also Figure 1 and Figure 5 In some embodiments, the first side portion 12 is provided with an opening 110, and the first side portion 12 includes a first area 120 and a second area 121. Along the vertical direction H, the first area 120 is located above the second area 121, and the opening and closing portion 50 is detachably connected to the first area 120 and the second area 121. The opening and closing portion 50 can be translated relative to the first area 120 and the second area 121 along the first direction a to open or close the opening 110, thereby realizing the switching of the opening and closing portion 50 between the first state and the second state, and the first direction a is perpendicular to the vertical direction H.

[0063] In this way, the translational opening and closing portion 50 helps the user to operate more stably when taking out the energy storage device 40 , thereby reducing the risk of the energy storage device 40 accidentally falling.

[0064] Specifically, the opening and closing portion 50 can be detachably connected to the first area 120 and the second area 121 by means of a snap connection, a zipper or Velcro. For example, the opening and closing portion 50 may include a connecting section and a hand-held section. The connecting section may be provided with two groups of spaced buttons with protrusions. A corresponding group of buttons with snap holes may be provided on the first area 120. And, a corresponding group of buttons with snap holes may be provided on the second area 121. One end of the connecting section is connected to both the first area 120 and the second area 121. The other end of the connecting section is connected to the hand-held section. The connecting section may be made of a flexible material such as nylon or polyester. Since the connecting section is made of a flexible material, the translation stroke of the opening and closing portion 50 can be set to be larger, which is beneficial to the access of the energy storage device 40.

[0065] When the energy storage device 40 needs to be stored, the buttons between the hand-held section and the first area 120 and the hand-held section and the second area 121 are unfastened at the same time, and the hand-held section is pulled along the first direction a to straighten the connecting section, thereby opening the opening 110. When the energy storage device 40 needs to be taken out, the hand-held section is pushed along the first direction a to close the connecting section, and the buttons on the hand-held section are engaged with the corresponding buttons on the first area 120 and the second area 121, thereby closing the opening 110.

[0066] For another example, the opening and closing part 50 may include a connecting section and a handheld section. Two sets of spaced Velcro with a fuzzy surface may be provided on the connecting section. A corresponding set of Velcro with a hook surface may be provided on the first area 120. And, a corresponding set of Velcro with a hook surface may be provided on the second area 121. One end of the connecting section is connected to both the first area 120 and the second area 121. The other end of the connecting section is connected to the handheld section. A slider extending along the first direction a may be provided on the connecting section. The inner surface of the main body 10 that forms the receiving space 11 may be provided with a slide rail extending along the first direction a. The dimensions of the slide rail and the slider along the first direction a may be less than half of the thickness of the main body 10.

[0067] When the energy storage device 40 needs to be stored, pull the handheld section along the first direction a so that the slider slides relative to the slide rail, and the handheld section separates from the opening 110 and gradually moves away from the opening 110. When the energy storage device 40 needs to be taken out, push the handheld section along the first direction a so that the slider slides relative to the slide rail, and the handheld section approaches the opening 110 and finally closes the opening 110.

[0068] Wherein, the first direction a includes two directions that are in the same straight line and opposite in direction.

[0069] It should be noted that in Figure 5 , the areas shown by the first area 120 and the second area 121 are only examples for easy understanding and cannot be used as a limitation to this embodiment.

[0070] Please refer to Figure 6 , in some embodiments, the second side 13 is provided with an opening 110. The second side 13 includes a third area 130 and a fourth area 131. Along the vertical direction H, the third area 130 is located above the fourth area 131. The opening and closing part 50 is detachably connected to both the third area 130 and the fourth area 131. The opening and closing part 50 can translate relative to the third area 130 and the fourth area 131 along the second direction to open or close the opening 110, so as to realize the switching of the opening and closing part 50 between the first state and the second state. The second direction is perpendicular to the vertical direction H.

[0071] Thus, since the photovoltaic module 20 is provided on the first side 12, it is convenient to provide a larger area of the photovoltaic module 20 on the first side 12 by providing the opening 110 on the second side 13. In addition, the translational opening and closing part 50 helps the user to operate more stably when taking out the energy storage device 40, reducing the risk of accidental dropping of the energy storage device 40.

[0072] Specifically, the opening and closing portion 50 can be detachably connected to the third area 130 and the fourth area 131 by means of a snap connection, a zipper or Velcro. For example, the opening and closing portion 50 may include a connecting section and a hand-held section. The connecting section may be provided with two groups of spaced buttons with protrusions. A corresponding group of buttons with snap holes may be provided on the third area 130. And, a corresponding group of buttons with snap holes may be provided on the fourth area 131. One end of the connecting section is connected to both the third area 130 and the fourth area 131. The other end of the connecting section is connected to the hand-held section. The connecting section may be made of a flexible material such as nylon or polyester. Since the connecting section is made of a flexible material, the translation stroke of the opening and closing portion 50 can be set to be larger, which is beneficial to the access of the energy storage device 40.

[0073] When the energy storage device 40 needs to be stored, the buttons between the hand-held section and the third area 130, and between the hand-held section and the fourth area 131 are unfastened at the same time, and the hand-held section is pulled along the second direction to straighten the connecting section, thereby opening the opening 110. When the energy storage device 40 needs to be taken out, the hand-held section is pushed along the second direction to close the connecting section, and the buttons on the hand-held section are engaged with the corresponding buttons on the third area 130 and the fourth area 131, thereby closing the opening 110.

[0074] For another example, the opening and closing portion 50 may include a connecting section and a hand-held section. The connecting section may be provided with two groups of spaced Velcro with a fleece surface. A corresponding group of Velcro with a hook surface may be provided on the third area 130. And, a corresponding group of Velcro with a hook surface may be provided on the fourth area 131. One end of the connecting section is connected to both the third area 130 and the fourth area 131. The other end of the connecting section is connected to the hand-held section. The connecting section may be provided with a slider extending along the second direction. The inner surface of the main body 10 forming the receiving space 11 may be provided with a slide rail extending along the second direction. The size of the slide rail and the slider along the second direction may be less than half of the thickness of the main body 10.

[0075] When the energy storage device 40 needs to be stored, the hand-held section is pulled along the second direction to slide the slider relative to the slide rail, and the hand-held section is separated from the opening 110 and gradually moves away from the opening 110. When the energy storage device 40 needs to be taken out, the hand-held section is pushed along the second direction to slide the slider relative to the slide rail, and the hand-held section approaches the opening 110 and finally closes the opening 110.

[0076] The second direction includes two directions that are in the same straight line and in opposite directions. The second direction may be parallel to the width direction of the main body 10 .

[0077] It should be noted that in Figure 6 In the figure, the areas indicated by the third area 130 and the fourth area 131 are merely examples for easy understanding and cannot be used as a limitation to this embodiment.

[0078] In some embodiments, the number of energy storage devices 40 is plural, and the number of accommodation spaces 11 is plural. The energy storage devices 40 and the accommodation spaces 11 are in one-to-one correspondence. In the second state, the opening and closing part 50 closes the opening 110 so that the plural energy storage devices 40 are respectively accommodated in the plural accommodation spaces 11.

[0079] In this way, the plural energy storage devices 40 are respectively accommodated in the plural accommodation spaces 11, reducing the movement and mutual collision of the energy storage devices 40 inside the backpack 100, reducing the risk of damage, increasing the use safety of the energy storage devices 40, and prolonging the service life of the energy storage devices 40. By providing the plural energy storage devices 40, the backpack 100 can provide a larger electric energy storage capacity, and at the same time allows the user to select different energy storage devices 40 according to different power consumption requirements, improving the flexibility of energy storage.

[0080] Specifically, the number of energy storage devices 40 can be two, three, four or even more. The number of accommodation spaces 11 can also be two, three, four or even more. For example, the number of energy storage devices 40 is two. The number of accommodation spaces 11 is also two. The two energy storage devices 40 are respectively accommodated in the two accommodation spaces 11. Among them, the two accommodation spaces 11 can be separated by a cloth belt or a plastic plate. The openings 110 of the accommodation spaces 11 can be provided on the same side of the main body part 10, or can be provided on different sides of the main body part 10.

[0081] Please refer to Figure 3 , in some embodiments, the opening and closing part 50 includes a support member 53 and a limiting member 54. The limiting member 54 is connected to opposite ends of the support member 53, and the limiting member 54 protrudes from a side of the support member 53 close to the energy storage device 40.

[0082] In this way, the support member 53 provides a placement platform for the energy storage device 40, enabling the energy storage device 40 to be stably supported. The limiting member 54 can reduce the risk of accidental dropping of the energy storage device 40 caused by slipping during the process of taking and placing, improving the safety of operation.

[0083] Specifically, the support member 53 can be made of a flexible material such as flexible nylon or polyester, such as a cloth strip. The support member 53 can also be made of a hard or semi-hard material. For example, the support member 53 can be a plastic plate. The limiting member 54 can also be a cloth strip or a plastic plate connected to opposite ends of the support member 53. During the process of accommodating the energy storage device 40, the energy storage device 40 can be placed on the support member 53, and then by rotating the opening and closing part 50, or translating the opening and closing part 50, etc., the energy storage device 40 is accommodated in the accommodation space 11. During this process, the energy storage device 40 may slide, so the provision of the limiting member 54 can reduce the probability of the energy storage device 40 dropping.

[0084] In some embodiments, the surface of the support member 53 facing the energy storage device 40 may be provided with anti-slip textures or designed to be a plush surface to increase the friction force on the energy storage device 40 and reduce the probability of the energy storage device 40 slipping.

[0085] Please refer to Figure 2 , in certain embodiments, a first through hole 14 is provided on one side of the main body portion 10 close to the photovoltaic module 20. The first through hole 14 communicates with the accommodation space 11. The interface assembly 30 includes a base 31. An output interface 32 is provided on the base 31. The base 31 is connected to the main body portion 10. A second through hole 15 is provided on one side of the main body portion 10 close to the base 31. The second through hole 15 communicates with the accommodation space 11.

[0086] It can be understood that the photovoltaic module 20 and the energy storage device 40 can be connected by a cable 60. The energy storage device 40 and the output interface 32 can also be connected by a cable 60. The first through hole 14 and the second through hole 15 allow the cable 60 to pass through, thus providing a channel for the cable 60. Since the first through hole 14 is provided on one side of the main body portion 10 close to the photovoltaic module 20 and the second through hole 15 is provided on one side of the main body portion 10 close to the base 31, the cable 60 is prevented from being exposed outside, reducing the possibility of the cable 60 being damaged or causing safety risks.

[0087] Specifically, the cable 60 between the photovoltaic module 20 and the energy storage device 40 can pass through the first through hole 14. The shape of the first through hole 14 can be a regular shape such as a circle or a square, or an irregular shape. For example, the shape of the first through hole 14 is a circle, which is beneficial to the arrangement of the cable 60. Since the first through hole 14 is provided on one side of the main body portion 10 close to the photovoltaic module 20, the photovoltaic module 20 can shield the above-mentioned cable 60.

[0088] The cable 60 between the energy storage device 40 and the interface assembly 30 can pass through the second through hole 15. The shape of the second through hole 15 can be a regular shape such as a circle or a square, or an irregular shape. For example, the shape of the second through hole 15 is a circle, which is beneficial to the arrangement of the cable 60. Since the second through hole 15 is provided on one side of the main body portion 10 close to the base 31, the base 31 can shield the above-mentioned cable 60.

[0089] The base 31 can be a part for installing and fixing the output interface 32. The base 31 and the main body portion 10 can be connected in a non-removable manner such as sewing or gluing, or in a removable manner such as snap connection, using a zipper, Velcro, etc.

[0090] The output interface 32 can be an interface for a user to connect an external device for charging or data transmission. The output interface 32 can include a USB or other types of charging and data transmission interfaces to meet the connection requirements of different devices.

[0091] In some embodiments, the output interface 32 is disposed at the bottom of the base 31. The output interface 32 is recessed into the base 31 along the vertical direction H, and the depth of the output interface 32 recessed into the base 31 is less than the dimension of the base 31 along the vertical direction H. In this way, other parts of the base 31 can be used to shield the output interface 32. Therefore, the output interface 32 is not easily eroded by rainwater, which helps to extend the service life of the output interface 32 and reduce damage or corrosion caused by moisture.

[0092] Please refer to Figure 2 , in certain embodiments, the main body portion 10 further has a storage space 16, and the storage space 16 is isolated from the accommodation space 11.

[0093] In this way, by isolating the storage space 16 from the accommodation space 11, the probability of interference between the energy storage device 40 and the items stored in the storage space 16 is effectively reduced, and the risk of damage to the energy storage device 40 caused by friction, impact or pressure is reduced, thereby extending the service life of the energy storage device 40. At the same time, the opening and closing portion 50 allows the user to quickly open or close the opening 110 of the accommodation space 11, realizing the quick access to the energy storage device 40 and improving the usability.

[0094] Specifically, the volume of the accommodation space 11 may be smaller than the volume of the storage space 16. This can prevent the accommodation space 11 from occupying too much internal space of the backpack 100, thus ensuring the storage function of the backpack 100. A partition may be provided between the storage space 16 and the accommodation space 11. The partition may be a cloth strip made of a flexible material such as nylon or polyester. A zipper may be provided on the partition so that the storage space 16 and the accommodation space 11 can be communicated when needed. The partition may also be provided with a shockproof layer or a buffer layer made of materials such as sponge or foam to protect the energy storage device 40 from impact.
