Technical Field

[0001] This utility model relates to the field of backpack technology, and in particular to a backpack with a modular charging and positioning module. Background Technology

[0002] Backpacks (double-shoulder bags or single-shoulder bags, etc.) are common items carried by people when going out. To meet the growing needs of people, existing backpacks usually include a locator module and a USB charging module. The locator module is used for backpack positioning, and the USB module is used to charge electronic devices (such as mobile phones, tablets, etc.), as shown in an existing patent (publication number: CN114391710A) which discloses an outdoor smart backpack. However, the locator module and the USB interface on this backpack are separately located in different positions on the backpack. In this case, the control circuit board and the USB interface mounted on the control circuit board form the backpack's USB charging module.

[0003] In summary, the existing backpacks have separate locator modules and USB charging modules, which cannot be modularly integrated. This not only takes up space on the backpack but also affects its overall aesthetics. Furthermore, the separate installation of the locator module and USB charging module results in poor concealment of the locator module. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a backpack with a modular charging and positioning module. It aims to solve the technical problem that existing backpacks have separate installations of the locator module and the USB charging module, which cannot be modularly integrated. This not only occupies space on the backpack but also results in low concealment of the locator module and affects the overall aesthetics of the backpack.

[0005] To address the aforementioned issues, this utility model provides a backpack with a modular charging and positioning module, comprising a backpack body and a charging and positioning module. The charging and positioning module includes a housing, a USB charging module, and a locator module. The housing is disposed on the backpack body, and the USB charging module is mounted on the housing. The USB charging module is used to electrically connect to a charging power source located inside the backpack body. The locator module is detachably disposed on the USB charging module, and the locator module is in electrical contact with the USB charging module.

[0006] Furthermore, the USB charging module has an installation slot, and the opposite sides of the locator module or the opposite sides of the installation slot are provided with sliding grooves. The opposite sides of the installation slot or the opposite sides of the locator module are provided with guide parts, and each guide part corresponds to each sliding groove and is slidably adapted.

[0007] Furthermore, the locator module and the USB charging module are detachably connected via a snap-fit ​​structure.

[0008] Furthermore, the locator module and the USB charging module are detachably connected via a threaded structure.

[0009] Furthermore, the locator module and the USB charging module are detachably connected via a magnetic structure.

[0010] Furthermore, the locator module is provided with a first contact, and the USB charging module is provided with a second contact, with the first contact and the second contact making electrical contact.

[0044] Please refer to Figure 1 - Figure 21 This utility model provides a backpack with a modular charging and positioning module.

[0045] Reference Figure 1 - Figure 6 The backpack in this embodiment includes a backpack body 1 and a charging and positioning module 2. The charging and positioning module 2 includes a housing 20, a charging and positioning integrated module, a partition 22, and a sliding cover 23.

[0046] Reference Figure 1 - Figure 6 The shell 20 is mounted on the backpack body 1. The shell 20 includes an inner shell 201 and an outer shell 202. The packing fabric 10 of the backpack body 1 has an installation opening 101. The inner shell 201 is located inside the backpack body 1. The first end of the inner shell 201 is attached to the packing fabric 10 of the backpack body 1.

The outer shell 202 and the inner shell 201 can be fixed with screws.

[0047] Of course, the second end of the outer shell 202 is located outside the backpack body 1. 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; a travel groove 2023 communicating with the inner cavity of the shell 20 is provided on the second end face of the outer shell 202. The travel groove 2023 is an oblong groove. Long strip grooves 2024 are provided on the opposite side walls of the travel groove 2023. The long strip grooves 2024 extend in the same direction as the travel groove 2023.

[0048] Reference Figure 3 - Figure 6The charging and positioning integrated module includes a USB charging module 21 and a locator module 24. The USB charging module 21 is mounted on the housing 20 and is used to electrically connect to a charging power supply located inside the backpack body. The locator module 24 is detachably mounted on the USB charging module 21 and is in electrical contact with the USB charging module 21. The USB charging module 21 has a first contact and a USB interface 211. The first contact is a first pin 215. The USB input cable 210 of the USB charging module 21 passes through the cable through the slot 2011 and exits the housing 20, and is used to electrically connect to a charging power supply 3 located inside the backpack body 1. The charging power supply 3 is used to supply power to the USB charging module 21. Of course, the first pin 215 and the USB interface 211 are both electrically connected to the circuit board inside the USB charging module 21. The USB interface 211 serves as the USB output port of the USB charging module 21. The USB interface 211 can be a USB Type-C interface or a USB Type-A interface, which is not limited here. In addition, the USB charging module 21 is provided with a mounting slot 213, and guide portions 214 or sliding grooves 240 are provided on opposite sides of the mounting slot 213.

[0049] Reference Figure 5 , Figure 16 and Figure 17 The USB charging module 21 is detachably connected to the housing 20 via a snap-fit ​​structure. Specifically, the USB charging module 21 has a first snap-fit ​​212 on its opposite side walls, and the housing 20 has a first slot 2021 on its opposite side walls. The first slot 2021 is located on the opposite side walls of the housing 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 housing 202 for easy replacement.

[0050] Reference Figure 5 - Figure 9 The locator module 24 is installed inside the housing 20. The locator module 24 is provided with a second contact. The second contact of the locator module 24 makes electrical contact with the first contact on the USB charging module 21, thereby realizing the electrical conduction between the locator module 24 and the USB charging module 21.

[0051] The locator module 24 is equipped with a lithium battery 244, which powers the locator module 24. Alternatively, the locator module 24 can also be powered by the USB charging module 21 mentioned above.

[0052] Specifically, the locator module 24 includes a housing 241, a control motherboard 242, a positioning chip 243, a second PIN pin 245, and a lithium battery 244. The control motherboard 242 and the lithium battery 244 are both housed within the housing 241. The positioning chip 243 is mounted on the control motherboard 242, and the lithium battery 244 is electrically connected to the control motherboard 242, primarily supplying power to the positioning chip 243. The positioning chip 243 is electrically connected to the motherboard for communication with the smart mobile terminal 4 (such as a mobile phone or tablet). The second PIN pin 245 is electrically connected to the control motherboard 242 and serves as the second contact point mentioned above. Therefore, it can be understood that the positioning signal emitted by the positioning chip 243 allows the APP on the smart mobile terminal 4, which controls the locator module 24, to monitor the backpack's location in real time, thus achieving the positioning function.

[0053] In one embodiment, reference is made to Figure 7 and Figure 8 The locator module 24 and the USB charging module 21 are detachably connected via a sliding groove structure. Specifically, the outer shell 241 of the locator module 24 has sliding grooves 240 or guide portions 214 on opposite sides. Each guide portion 214 on the locator module 24 corresponds one-to-one with each sliding groove 240 on the USB charging module 21 and is slidably adapted; or, each sliding groove 240 on the locator module 24 corresponds one-to-one with each guide portion 214 on the USB charging module 21 and is slidably adapted. For example, the guide portion 214 on the locator module 24 is slid along the sliding groove 240 in the mounting groove 213, so that the locator module 24 slides into the mounting groove 213, thereby connecting the locator module 24 and the USB charging module 21.

[0054] In another exemplary embodiment, the slide groove 240 on the locator module 24 is slid along the guide portion 214 within the mounting groove 213, allowing the locator module 24 to slide into the mounting groove 213, thus connecting the locator module 24 to the USB charging module 21. After the locator module 24 is connected to the USB charging module 21, the second pin 245 on the locator module 24 makes electrical contact with the first pin 215 on the USB charging module 21, achieving electrical contact between the locator module 24 and the USB charging module 21. When the USB input cable 210 of the USB charging module 21 is electrically connected to the charging power supply 3 located inside the backpack body 1, the charging power supply 3 can supply power to both the USB charging module 21 and the locator module 24. When the lithium battery 244 of the locator module 24 is fully charged, the battery level can be displayed on the APP used to control the locator module 24 on the smart mobile terminal 4, while the control motherboard 242 cuts off the current transmission from the USB charging module 21 to the locator module 24.

[0055] In other embodiments, the locator module 24 and the USB charging module 21 can also be detachably connected via a snap-fit ​​structure. The snap-fit ​​structure used between the locator module 24 and the USB charging module 21 is an existing snap-fit ​​structure and will not be described here. Alternatively, the locator module 24 and the USB charging module 21 can be detachably connected via a threaded structure. For example, a threaded hole is provided on the locator module 24, and a threaded post is provided on the USB charging module 21 that matches the thread of the threaded hole, thus achieving a threaded connection between the locator module 24 and the USB charging module 21. Alternatively, the locator module 24 and the USB charging module 21 can be detachably connected via a magnetic attraction structure. For example, a magnet is provided on both the locator module 24 and the USB charging module 21, and the magnets on the locator module 24 and the USB charging module 21 attract each other, thus achieving the magnetic attraction between the locator module 24 and the USB charging module 21. Alternatively, the locator module 24 and the USB charging module 21 can be detachably connected via fasteners. When the locator module 24 is connected to the USB charging module 21 via fasteners (screws), such as... Figure 10 - Figure 12 As shown, the locator module 24 can be located on the surface of the USB charging module 21 facing away from the USB interface 211. Alternatively, the locator module 24 and the USB charging module 21 can also be connected via a means such as... Figure 13 - Figure 15 The structural connections shown are not limited here. Therefore, those skilled in the art can reasonably modify the detachable connection structure between the locator module 24 and the USB charging module 21, and such modifications should also fall within the protection scope of this utility model.

[0056] In one embodiment, reference is made to Figure 4 , Figure 5 , Figure 18 and Figure 19 The partition 22 is disposed between the travel groove 2023 and the charging positioning integrated module, and the partition 22 is detachably connected to the housing 20 via a snap-fit ​​structure. Specifically, a second snap-fit ​​221 is provided on the opposite side walls of the partition 22, and a second slot 2022 is provided on the opposite side walls of the housing 20. The second slot 2022 is specifically provided on the opposite side walls of the outer shell 202, and the second slot 2022 is adapted to engage with the second snap-fit ​​221, so that the partition 22 can be removed from the outer shell 202 for easy replacement. In addition, the partition 22 is provided with a socket 220 corresponding to and communicating 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 travel groove 2023, and a first protrusion 2026 and a second protrusion 2027 are respectively provided at opposite ends of the sliding groove 2025.

[0057] 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.

[0058] Reference Figure 4 , Figure 5 , Figure 20 and Figure 21 The sliding cover 23 is slidably disposed within the travel groove 2023, and the sliding cover 23 is slidably attached to the partition 22. The surfaces of the partition 22 and the sliding cover 23 are smooth, facilitating the sliding of the sliding cover 23. The partition 22 also supports the sliding cover 23. Sliding portions 230 are fixed on opposite side walls of the sliding cover 23, and the sliding cover 23 and the sliding portions 230 are integrally connected. 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. Specifically, 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.

[0059] In addition, an annular sealing ring (not shown) is provided between the partition 22 and the sliding cover 23. An annular groove is provided on the surface of the partition 22 facing the travel groove 2023. The annular groove is located around the aforementioned socket 220. The annular sealing ring is installed in the annular groove to seal the gap between the partition 22 and the sliding cover 23. Thus, 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.

[0060] In summary, firstly, 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.

[0061] Second: When in use, the charging and positioning module on the backpack of this utility model connects the USB input cable 210 of the USB charging module 21 to the charging power supply 3 located inside the backpack body 1. Since the locator module 24 is in electrical contact with the USB charging module 21, the charging power supply 3 supplies power to both the USB charging module 21 and the locator module 24. The locator module 24 enables the backpack to be positioned. The USB interface 211 on the USB charging module 21 connects to a mobile terminal (such as a mobile phone or tablet) that needs charging, thus charging the mobile terminal. Therefore, the charging and positioning module on the backpack of this utility model modularly integrates the locator module 24 and the USB charging module 21, avoiding their separate installation, thereby saving space on the backpack and improving its overall aesthetics.

[0062] Third, the integration of the locator module 24 with the USB charging module 21 makes it more discreet and harder to spot, making it easier to find a lost backpack.

[0063] Fourth: When the charging power supply 3 inside the bag charges the smart mobile terminal 4 (mobile phone or tablet computer, etc.) outside the bag through the USB charging module 21, the locator module 24 itself has a lithium battery 244. When the lithium battery 244 has low power, it charges the locator through the USB charging module 21. When the lithium battery 244 of the locator module 24 is fully charged, the control motherboard 242 of the locator module 24 cuts off the current transmission from the USB charging module 21 to the locator module 24, which protects the locator module 24.

[0064] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
