The outer housing 202 and the inner housing 201 can be fixed together with screws. Of course, the second end of the outer shell 202 is located outside the backpack body 1, and the packing fabric 10 of the backpack body 1 is sandwiched between the first end of the inner shell 201 and the second end of the outer shell 202. The first end of the outer shell 202 has an open structure, so that the inner cavity of the outer shell 202 communicates with the inner cavity of the inner shell 201 to form the inner cavity of the shell 20. In addition, a threading slot 2011 is also provided on the inner shell 201.

[0035] Reference Figure 1 - Figure 5 The USB charging module 21 is installed inside the housing 20. The USB charging module 21 has a USB input cable 210, which passes through the aforementioned cable tray 2011. The USB input cable 210 is used to electrically connect to the charging power supply 3 located inside the bag. The charging power supply 3 is mainly used to supply power to the USB charging module 21. The USB charging module 21 also has a USB interface 211, which serves as the USB output port of the USB charging module 21. The USB interface 211 can be either a USB Type-C interface or a USB Type-A interface; this is not limited here and can be reasonably changed according to actual needs. The shell 20 has a travel groove 2023 that communicates with the USB interface 211. Specifically, the travel groove 2023 is formed on the second end face of the shell 202. The travel groove 2023 is located outside the backpack body 1 and is located around the USB interface 211. The travel groove 2023 is an oblong groove. The length of the travel groove 2023 is greater than the length of the USB interface 211. Long strip grooves 2024 are formed on the opposite side walls inside the travel groove 2023. The long strip grooves 2024 extend in the same direction as the travel groove 2023.

[0036] Reference Figure 5 - Figure 7In this embodiment, the USB charging module 21 is detachably connected to the housing 20 via a snap-fit ​​mechanism. Specifically, the USB charging module 21 has a first snap-fit ​​212 on its opposite side walls, and a first slot 2021 is formed on the opposite side walls of the housing 20. The first slot 2021 is formed on the opposite side walls of the outer casing 202, and the first slot 2021 is adapted to engage with the first snap-fit ​​212, so that the USB charging module 21 can be removed from the outer casing 202 for easy replacement of the USB charging module 21.

[0037] Reference Figure 3 - Figure 5 , Figure 8 and Figure 9 The partition 22 is disposed between the travel groove 2023 and the USB charging module 21, and the partition 22 is detachably connected to the housing 20 by means of a snap fastener. Specifically, a second snap fastener 221 is provided on the opposite side walls of the partition 22, and a second slot 2022 is provided on the opposite side walls inside the housing 202. The second slot 2022 and the second snap fastener 221 are adapted to engage, so that the partition 22 can be removed from the housing 202 for easy replacement of the partition 22.

[0038] Reference Figure 3 - Figure 5 The partition 22 has a socket 220 that corresponds to and communicates with the USB interface 211. The distance between the partition 22 and the elongated groove 2024 forms a sliding groove 2025. The sliding groove 2025 extends in the same direction as the aforementioned travel groove 2023. The opposite ends of the sliding groove 2025 are respectively provided with a first protrusion 2026 and a second protrusion 2027.

[0039] Of course, in other embodiments, sliding grooves 2025 can be directly opened on the opposite side walls of the travel groove 2023, without the need to set the partition 22 and the elongated groove 2024 mentioned above.

[0040] In addition, an annular groove is formed on the surface of the partition 22 facing the travel groove 2023. The annular groove is located around the socket 220. An annular sealing ring is installed in the annular groove to seal the gap between the partition 22 and the sliding cover 23. When the sliding cover 23 slides along the sliding groove 2025 to the position of the socket 220 and covers the socket 220, the annular sealing ring can play a waterproof role, preventing rainwater from entering the USB interface 211 from the position of the socket 220.

[0041] Reference Figure 3 - Figure 5 , Figure 10 and Figure 11The sliding cover 23 is slidably disposed within the travel groove 2023, and the sliding cover 23 is slidably fitted with the partition 22. The surfaces of the partition 22 and the sliding cover 23 are smooth, facilitating the sliding of the sliding cover 23. Simultaneously, the partition 22 serves to support the sliding cover 23. Furthermore, sliding portions 230 are fixed on opposite side walls of the sliding cover 23, integrally connected to the sliding cover 23. The sliding portions 230 slide along the aforementioned sliding groove 2025, which guides the sliding of the sliding cover 23. A limiting groove 231 is formed on the sliding portion 230, which is used to slidably engage with the first protrusion 2026 or the second protrusion 2027.

[0042] When the sliding cover 23 covers the USB interface 211, the first protrusion 2026 is limited within the limiting groove 231; when the sliding cover 23 opens the USB interface 211, the second protrusion 2027 is limited within the limiting groove 231.

[0043] In summary, when the USB interface 211 is needed, the sliding cover 23 is slid along the sliding groove 2025, causing the limiting groove 231 on the sliding cover 23 to slide to the position of the second protrusion 2027. At this time, the USB interface 211 is in the open state, and the second protrusion 2027 is limited within the limiting groove 231, preventing the sliding cover 23 from sliding freely. When the USB interface 211 is not in use, the sliding cover 23 is slid along the sliding groove 2025, causing the limiting groove 231 on the sliding cover 23 to slide to the position of the first protrusion 2026. At this time, the USB interface 211 is in the closed state, and the first protrusion 2026 is limited within the limiting groove 231. The sliding cover 23 is not easily opened by itself, making it convenient to use.

[0044] Additionally, refer to Figure 2 When it is necessary to use the USB charging module 21 to charge the smart mobile terminal 4 (such as a mobile phone or tablet computer) outside the bag, connect the USB input cable 210 of the USB charging module 21 to the charging power supply 3 placed inside the bag, slide the sliding cover 23 to open the USB interface 211, and insert the USB port 220 of the charging cable of the electronic device or smart mobile terminal 4 outside the bag into the USB interface 211 to achieve charging.
