[0031] Before describing the embodiments in detail, it should be understood that this application is not limited to the detailed structures or element arrangements described below or in the accompanying drawings. This application can be implemented in other ways. Furthermore, it should be understood that the wording and terminology used herein are for descriptive purposes only and should not be construed as limiting. The terms "comprising," "including," "having," and similar expressions used herein mean to include the items listed thereafter, their equivalents, and other additional items. In particular, when describing "an element," this application does not limit the number of elements to one, but may include multiple elements.

[0032] Please also refer to Figures 1 to 8 As shown, this application provides a portable charging device 10, which is, for example, a three-in-one power bank integrating a power bank, charger, and data cable. The portable charging device 10 includes a device body 12, a charging plug 14, and a first data cable 16. The charging plug 14 is detachably connected to the device body 12. The device body 12 is provided with an electrical connector for electrical connection to external devices. One end of the first data cable 16 is connected to the charging plug 14, and the other end is connected to the device body 12. The first data cable 16 is electrically connected to the electrical connector and can be stored inside the device body 12 or between the charging plug 14 and the device body 12. The external device can be, for example, a mobile phone, tablet computer, laptop computer, electric shaver, digital camera, or other rechargeable devices.

[0033] This application sets the charging plug 14, which has a charging module, and the device body 12, which has a battery cell, as detachable structures, enhancing the product's functionality and expanding its application scenarios and scope. When the portable charging device 10 is not in use, the charging plug 14 is connected to the device body 12 to improve portability. When the portable charging device 10 is in use, the charging plug 14 can be detached and plugged into a socket. At this time, the first data line 16 will be stretched outward, and the charging cable connected to the charging device is set on the device body 12. Because the extension length of the first data line 16 is increased between the charging plug 14 and the device body 12, the charging distance is extended. The charging distance can be understood as the distance between the charging connector and the charging plug 14 (the charging distance in the prior art is the distance between the charging connector and the device body 12). After the charging plug 14 is detached from the device body 12, the small size and weight of the charging plug 14 reduce the probability of the charging plug 14 falling out of the socket, enhance the stability of the plugging, and prevent the large size from blocking other socket ports. In addition, the charging module is the main heat-generating component. Keeping the main heat-generating component away from the battery cell can improve the battery cell's lifespan and also prevent users from experiencing the discomfort of their hands getting too hot when touching the main body of the device.

[0034] In the illustrated embodiment, as Figure 1 and Figure 3As shown, the portable charging device 10 is generally square in shape, and the corners of the portable charging device 10 can be designed with rounded structures to improve the tactile feel and aesthetics of the portable charging device 10. The portable charging device 10 has mutually perpendicular length direction a, width direction b, and thickness direction c. Specifically, the device body 12 includes a first shell 18, which forms a first mounting space 20. The first mounting space 20 contains a battery cell 22, a main circuit board 24, and a storage assembly. The storage assembly is used to store the data cable and can include at least one storage module. For example, when the storage assembly includes two storage modules, the two storage modules are arranged along the length direction a. The battery cell 22 can be used to store and release electrical energy, i.e., charging and discharging.

[0035] When the charging plug 14 is plugged into the socket and the electrical connector is not connected to the device to be charged, the battery cell 22 begins to store electricity for charging; when the charging plug 14 is plugged into the socket and the electrical connector is connected to the device to be charged, the device to be charged begins to charge, or the device to be charged and the battery cell 22 charge simultaneously; when the charging plug 14 is not plugged into the socket and the electrical connector is connected to the device to be charged, the battery cell 22 begins to discharge to charge the device to be charged.

[0036] In this embodiment, as Figure 3 As shown, the battery cell 22 and the main circuit board 24 are arranged along a first direction. The storage assembly may include a first storage module and a second storage module, which are arranged along the first direction. The first storage module and / or the second storage module are arranged with the battery cell 22 along a second direction. For example, the storage assembly, the battery cell 22, and the main circuit board 24 are arranged along the second direction, meaning the battery cell 22 and the main circuit board 24 are located on one side of the storage assembly. This improves the utilization rate of the internal space of the device body 12, allowing the device body 12 to be designed to be smaller and improving product portability. The main circuit board 24 is located on the side of the battery cell 22 away from the charging plug 14. Preferably, the first direction is the length direction a, and the second direction is the thickness direction c. The electrical connector, the battery cell 22, and the first data cable 16 are electrically connected to the main circuit board 24.

[0037] Preferably, a mounting bracket (not shown) is also provided within the first mounting space 20. The battery cell 22, the storage components (first storage module, second storage module), and the main circuit board 24 are all mounted and fixed on the mounting bracket, facilitating assembly and improving the stability of the connection between components. Optionally, the mounting bracket is disposed between the battery cell 22, the main circuit board 24, and the storage components, and the mounting bracket is fixedly connected to the first housing 18. In other embodiments, the mounting bracket may not be provided, and the battery cell 22, the main circuit board 24, and the storage components may be fixedly connected to the inner wall of the first housing 18 respectively.

[0038] Furthermore, the first housing 18 includes a first housing portion 26 with an opening at one end and a second end portion 28 covering the opening end of the first housing portion 26. The second end portion 28 and the first housing portion 26 surround to form a first mounting space 20. The first housing portion 26 and the second end portion 28 can be fixedly connected or detachably connected.

[0039] like Figure 4 As shown, the charging plug 14 includes a second housing 30, which forms a second mounting space 32. A charging module 34 and a plug assembly 36 are disposed within the second mounting space 32. The first data cable 16 and the plug assembly 36 are electrically connected to the charging module 34, respectively. Figure 4 In the illustrated embodiment, the charging module 34 and the plug assembly 36 are arranged along a first direction. Optionally, a mounting bracket (not shown) may be provided in the second mounting space 32, the mounting bracket being fixedly connected to the second housing 30, and the charging module 34 and the plug assembly 36 being mounted on the mounting bracket; or, the charging module 34 and the plug assembly 36 may be mounted on the inner wall of the second housing 30.

[0040] The charging module 34 may include an AC-CDC module and a DC-CDC module. The AC-CDC module is electrically connected to the plug assembly 36 and the DC-CDC module respectively, and is used to convert AC power into DC power. The DC-CDC module is electrically connected to the first data line 16, and is used to convert the DC power input from the AC-CDC module into DC power of a specified voltage.

[0041] Specifically, the second housing 30 includes a second housing portion 38 with one end open and a first end portion 40 covering the open end of the second housing portion 38. The first end portion 40 and the second housing portion 38 enclose a second mounting space 32. The second housing portion 38 and the first end portion 40 can be fixedly connected or detachably connected. The charging module 34 is located between the first end portion 40 and the plug assembly 36.

[0042] In this embodiment, the plug assembly 36 includes a plug base 42 and a plug 44. The plug base 42 is electrically connected to the charging module 34, and the plug 44 is electrically connected to the plug base 42. The plug 44 can rotate and fold relative to the plug base 42 between a retracted position and an extended position. Correspondingly, the second housing portion 38 has a socket 46 at the end away from the first end portion 40. When the plug 44 is in the retracted position, the plug 44 is retracted into the socket 46. When the plug 44 is rotated to the extended position, the plug 44 extends out of the socket 46 to facilitate plugging into a socket. For example, when the plug 44 is in the extended position, the plug 44 is perpendicular to the end wall of the second housing portion 38 away from the first end portion 40.

[0043] Preferably, the second outer shell 30 can be made of silicone, such as soft silicone, which can serve as heat insulation and fit the mobile environment, providing protection against drops and scratches, and enhancing stability.

[0044] Please also refer to Figures 2 to 4 As shown, the charging plug 14 is detachably connected to the device body 12 to facilitate the assembly and disassembly of the charging plug 14 and the device body 12. Specifically, the charging plug 14 and the device body 12 are respectively provided with a first mating surface 14a and a second mating surface 12a. The first mating surface 14a is, for example, the side of the second end 28 facing away from the first housing portion 26, and the second mating surface 12a is, for example, the side of the first end 40 facing away from the second housing portion 38. The first mating surface 14a is provided with a first engaging portion, and the second mating surface 12a is provided with a second engaging portion. The first engaging portion and the second engaging portion are magnetically engaged or snap-fit ​​engaged, that is, the charging plug 14 and the device body 12 can be detachably connected by magnetic attraction, or by snap-fit, or by both magnetic attraction and snap-fit. This application does not limit the specific method of detachable connection.

[0045] Preferably, the surface of the charging plug 14 with the prongs 44 is the surface of the charging plug 14 opposite to the first mating surface 14a. This design allows the user to easily hold the device body 12, insert the prongs 44 into the electrical socket, and then easily separate the device body 12 from the charging plug 14, simplifying the separation operation. Correspondingly, the second mating surface 12a is located at one end of the length direction of the device body 12. In some embodiments, the surface of the charging plug 14 with the prongs 44 is the surface of the charging plug 14 adjacent to the first mating surface 14a. This design allows the charging plug 14 and the device body 12 to be arranged vertically when the portable charging device 10 is fixed to the wall socket by the charging plug 14. Compared with a horizontal arrangement, this prevents the device body 12 from protruding too much from the wall, reducing the chance of collision and fall when the user walks around. It also prevents the device body 12 from easily detaching from the charging plug 14 because its center of gravity is far away from the charging plug 14.

[0046] Furthermore, a positioning structure is provided between the charging plug 14 and the device body 12. The charging plug 14 and the device body 12 are positioned and connected through the positioning structure, which facilitates alignment and fixation, increases the ease of assembly and disassembly of the charging plug 14, and allows for more precise docking between the charging plug 14 and the device body 12. Simultaneously, it prevents the charging plug 14 from accidentally detaching from the device body 12 under forces applied in a non-positioning direction. Optionally, the positioning structure includes a first positioning part and a second positioning part that cooperate with each other. The first positioning part is disposed on the first mating surface 14a and located on one side of the first joint, and the second positioning part is disposed on the second mating surface 12a and located on one side of the second joint, thereby preventing the charging plug 14 and the device body 12 from rotating relative to each other in the magnetic attraction direction and accidentally separating.

[0047] In the illustrated embodiment, the charging plug 14 is detachably connected to the device body 12 via a magnetic attraction structure. This detachable connection means that the first end 40 and the second end 28 are detachably connected, and the first end 40 and the second end 28 are, for example, plate-like structures. The charging plug 14 is detachably connected to the end of the device body 12 along its length, a design that reduces the width of the portable charging device 10, making it easier to carry. Specifically, the magnetic attraction structure and the positioning structure are located between the first end 40 and the second end 28. The magnetic attraction structure includes a first magnetic member 48 (first part) and a second magnetic member 50 (second part) that magnetically attract each other. The first magnetic member 48 and the second magnetic member 50 can be magnets or magnetic metals, etc. Multiple first magnetic members 48 and second magnetic members 50 can be provided, for example, distributed at the four corners of the first end 40 and the second end 28 respectively, to avoid interference with the charging module 34 and the plug assembly 36. The number of first magnetic members 48 and the number of second magnetic members 50 are the same, and their positions correspond one-to-one. The first magnetic attractor 48 and the second magnetic attractor 50 are both columnar structures, for example. The first end 40 is provided with a first receiving groove 52, and the first magnetic attractor 48 is received in the first receiving groove 52. The second end 28 is provided with a second receiving groove 54, and the second magnetic attractor 50 is received in the second receiving groove 54.

[0048] Preferably, one of the first positioning part and the second positioning part is a protrusion and the other is a groove. The protrusion and the groove are engaged and respectively provided with magnetically attracted components, thereby achieving simultaneous positioning and detachable connection, simplifying the components and manufacturing process. For example, the first positioning part is a positioning post 56 (protrusion), and the second positioning part is a positioning groove 58 (groove). The positioning post 56 and the positioning groove 58 are mutually positioned and inserted. Multiple positioning posts 56 and positioning grooves 58 can be provided, for example, they can be distributed at the four corners of the first mating surface 14a and the second mating surface 12a, to avoid interference with the charging module 34 and the pin assembly 36. The number of positioning posts 56 and positioning grooves 58 is the same, and their positions correspond one-to-one. It should be understood that in other embodiments, the concave and convex structure of the positioning structure may also have other structural designs. For example, toothed meshing structures are respectively provided on the end edges of the first housing 18 and the second housing 30, and the two toothed meshing structures mesh with each other to achieve positioning; or, a groove is provided at the end of the first housing 18, and the end of the second housing 30 is configured to fit into the groove to achieve positioning. This application does not limit the specific implementation of the positioning structure.

[0049] In some embodiments, the first and second joints are magnetically engaged structures, and the first and second joints are concave-convex structures. The magnetic structure and the positioning structure are integrated together, thereby achieving both detachability and positioning. This allows the user to hold the device body 12, insert the charging plug 14 into the socket, and then hold the device body 12 along the disassembly direction (i.e., the magnetic direction) to detach it from the charging plug 14. This enables the user to perform the above operation with one hand, improving the convenience of use.

[0050] The electrical connector can be provided with one or more connectors or interfaces, enabling the portable charging device 10 to charge a single device or multiple devices simultaneously. In the illustrated embodiment, the electrical connector includes a second data line 60 and a data interface 62. The data interface 62 can be disposed on the device body 12, for example, at the end of the first housing 26 away from the second end 28, and the data interface 62 is electrically connected to the main circuit board 24. One end of the second data line 60 is electrically connected to the first data line 16, and the other end extends out of the device body 12 and is provided with a data connector 64, which is detachably connected to the device body 12.

[0051] Furthermore, a first storage module 66 and a second storage module 68 are provided within the first installation space 20. The second storage module 68 is located on the side of the first storage module 66 away from the charging plug 14. The first data cable 16 is retractably stored within the first storage module 66, and the second data cable 60 is retractably stored within the second storage module 68. The first storage module 66 and the second storage module 68 can be existing cable reels, and their specific structures will not be described in detail. The first storage module 66 and the second storage module 68 are both circular, for example. The first storage module 66 and the second storage module 68 are arranged along the first direction, and the axial directions of the first storage module 66 and the second storage module 68 are parallel to the thickness direction c. The first storage module 66 and the second storage module 68 are arranged along the second direction (thickness direction c) with the battery cell 22 and the main circuit board 24. This arrangement can further increase the charging distance of the device to be charged, enabling long-distance charging and increasing the convenience of use and multi-scenario application of the portable charging device 10.

[0052] The second data line 60 is electrically connected to the first data line 16. For example, the first storage module 66 has a first conductive member 70 on the side away from the battery cell 22, and the second storage module 68 has a second conductive member 72 on the side away from the battery cell 22. The first conductive member 70 and the second conductive member 72 are, for example, metal sheets. One end of the first data line 16 located in the first storage module 66 is connected to the first conductive member 70, and one end of the second data line 60 located in the second storage module 68 is connected to the second conductive member 72. The first storage module 66 and the second storage module 68 are electrically connected via a connecting circuit board or connecting wire. In this embodiment, the first storage module 66 and the second storage module 68 are electrically connected via a connecting circuit board 74. Specifically, the connecting circuit board 74 is located between the first storage module 66 and the second storage module 68, and one end of the connecting circuit board 74 is connected to the first conductor 70 (e.g., soldered) and the other end is connected to the second conductor 72 (e.g., soldered), thereby realizing the electrical connection between the second data line 60 and the first data line 16. The circuit board soldering method can improve production efficiency and the stability of the connection between the second data line 60 and the first data line 16.

[0053] In other embodiments, the first data cable 16 can be stored between the device body 12 and the charging plug 14. Specifically, the first data cable 16 can be configured as a magnetic data cable or a flexible data cable, that is, the outer sheath of the data cable core is magnetic or elastic, and the extension and retraction of the data cable and the automatic return to storage are realized through magnetic attraction and elastic recovery. Optionally, the magnetic data cable and the flexible data cable can be stacked axially or wound radially outward in a spiral. The magnetic attraction or elasticity is to keep the data cable in a stored state. Preferably, the charging plug 14 and / or the device body 12 are provided with a storage slot, for example, provided on the end face where the charging plug 14 connects to the device body 12 and / or on the end face where the device body 12 connects to the charging plug 14. The first data cable 16 is retractably stored in the storage slot. The device body 12 is provided with a main circuit board 24, and the end of the device body 12 is provided with a cable outlet 13. One end of the first data cable 16 passes through the cable outlet 13 and is electrically connected to the main circuit board 24. An electrical connector is electrically connected to the main circuit board 24 at the connection end of the device body. The second data cable 60 can also be set as a magnetic data cable or a flexible data cable. The specific structural design can refer to the first data cable 16 described above, and will not be repeated here.

[0054] One end of the first data cable 16 extending out of the device body 12 is fixedly or detachably connected to the first end 40, and the other end is movably passed through the second end 28. In this embodiment, one end of the first data cable 16 extending out of the device body 12 is fixedly connected to the first end 40 and electrically connected to the charging module 34. Specifically, the end of the device body 12 connected to the charging plug 14 is provided with an outlet 13. The first storage module 66 includes a rotatable first turntable. The end of the first data cable 16 connected to the device body 12 passes through the outlet 13 and is wound and stored on the first turntable, and is electrically connected to the main circuit board 24. The electrical connector is electrically connected to the main circuit board 24 at the connection end of the device body 12. Specifically, the second data cable 60 is connected to one end of the device body 12 and can be retracted and stored in the second storage module 68 and electrically connected to the main circuit board 24. The device body 12 is provided with a through-hole 76 and a mounting position 78. The mounting position 78 is, for example, a groove structure. One end of the second data cable 60 is movably passed through the through-hole 76 and wound and stored on the second turntable of the second storage module 68 and electrically connected to the first data cable 16 or the main circuit board 24. The data connector 64 is detachably installed in the mounting position 78. The through-hole 76 is located at the end of the device body 12 away from the second end 28, and the mounting position 78 is located at the end of the device body 12 away from the second end 28 or on the side wall of the device body 12 in the width or thickness direction. The data connector 64 is stored at the end of the device body 12 away from the charging plug 14, so that the user can grasp the part of the device body 12 near the charging plug 14 and then pull the data connector 64 and the second data cable 60 out of the device body 12, so as to avoid accidentally pulling the charging plug 14 off the socket during the cable pulling process.

[0055] Preferably, the first data line 16 is electrically connected to the first storage module 66, the second data line 60 is electrically connected to the second storage module 68, the first storage module 66 is electrically connected to the second storage module 68, and the main circuit board 24 is electrically connected to the first storage module 66, the second storage module 68, the connecting circuit board 74, or the connecting wires, thereby realizing the electrical connection between the first data line 16 and the second data line 60. In this embodiment, the main circuit board 24 is electrically connected to the connecting circuit board 74.

[0056] In such Figure 5In the illustrated embodiment, the electrical connector includes a third data cable 61, which is not configured as a retractable storage structure. Specifically, one end of the third data cable 61 located inside the device body 12 is electrically connected to the first data cable 16 or the main circuit board 24, and the third data cable 61 includes an exposed section 80 extending out of the device body 12. One end of the exposed section 80 is fixed relative to the device body 12, and a data connector 64 is connected to the other end of the exposed section 80. When the third data cable 61 is not in use, the data connector 64 can be fixedly stored in the mounting position 78, at which time the exposed section 80 can form a handle for easy carrying by the user; when the third data cable 61 needs to be used, the data connector 64 can be detached from the mounting position 78 for use.

[0057] In the illustrated embodiment, the outer surface of the charging plug 14 is smoothly adapted to the outer surface of the device body 12, so that when the charging plug 14 is connected to the device body 12, the entire outer surface is seamless, improving the aesthetics of the product, and also reducing the probability of the charging plug 14 accidentally separating from the device body 12 due to bumps.

[0058] In such Figures 6 to 8 In the embodiment shown, the charging module 34 includes a first circuit board 82 and a second circuit board 84 that are electrically connected. The plug assembly 36 and the second circuit board 84 are arranged on the first circuit board 82 along a third direction. The first circuit board 82 and the second circuit board 84 are electrically connected. The third direction is, for example, the width direction b mentioned above. The ACDC module is located on the first circuit board 82, and the DCDC module is located on the second circuit board 84. The first data line 16 is connected to the second circuit board 84 on a side offset from the first circuit board 82. The position of the first data line 16 connected to the second circuit board 84 corresponds to the position of the first storage module 66 inside the device body 12 for storing the first data line 16 in the first direction. For example, the position of the first data line 16 connected to the second circuit board 84 inside the second housing 30 corresponds to the position of the first storage module 66 inside the first housing 18. If they are set to the same side, the part of the first data line 16 outside the first storage module 66 extends approximately along the first direction, which is conducive to the extension and retraction of the first data line 16. On the other hand, since the first circuit board 82 is equipped with high-voltage components (such as transformers, high-voltage electrolytic capacitors, etc.), connecting the first data line 16 to the second circuit board 84 on a side offset from the first circuit board 82 can also increase the distance between the first data line 16 and the high-voltage components, further improving electrical safety.

[0059] More specifically, the first data cable 16 includes an internal cable body 86 located within the second housing 30, and a cable clamping structure is provided between the internal cable body 86 and the second housing 30. The cable clamping structure includes a first cable clamping part 88 and a second cable clamping part 90. The first cable clamping part 88 is fixed to the outer surface of the internal cable body 86, and the second cable clamping part 90 is fixed to the inner wall of the second housing 30. The first cable clamping part 88 and the second cable clamping part 90 engage to limit the internal cable body 86 and prevent the first data cable 16 from breaking due to excessive force during the stretching process.

[0060] In this embodiment, the first wire-locking portion 88 includes a first outward protrusion 92 and a second outward protrusion 94 spaced apart along a first direction. A slot 96 is formed between the first outward protrusion 92 and the second outward protrusion 94. The second wire-locking portion 90 is at least partially engaged in the slot 96, thereby limiting the internal wire body 86 in the first direction. The second wire-locking portion 90 is designed in a U-shape, for example. Correspondingly, the portion of the second wire-locking portion 90 around the U-shaped opening is engaged in the slot 96 for easy assembly. In some embodiments, the first wire-locking portion 88 further includes a connecting portion connecting the first outward protrusion 92 and the second outward protrusion 94. This connecting portion is connected to the outer surface of the internal wire body 86, that is, the slot 96 is formed on the circumferential periphery of the connecting portion.

[0061] Furthermore, the second outer casing 30 has a cable passage 98 at one end near the device body 12, i.e., the first end 40. The first data cable 16 passes through the cable passage 98, and a stop portion 100 is provided on the outer surface of the first data cable 16. The stop portion 100 is set against the inner or outer side wall of the first end 40 of the second outer casing corresponding to the cable passage 98. By setting the stop portion 100, on the one hand, it facilitates assembly. For example, the first storage module 66 can be made first, and then the first data cable 16 extending from the first storage module 66 can be inserted into the charging plug 14 and welded and fixed. The stopping function of the stop portion 100 can indicate that the installation is in place. On the other hand, the stopping function of the stop portion 100 and the first end 40 can cooperate with the cable clamping structure to limit and fix the cable. In this embodiment, the stop portion 100 is set inside the second outer casing 30 and abuts against the inner wall surface of the first end 40. The cable clamping structure is located on the side of the stop portion 100 away from the first end 40. By setting up a wire clamping structure and a stop part 100, the wire core inside the wire body can be prevented from bulging, misaligning or even breaking due to repeated pulling of the first data line 16, thus extending the product's stability and service life.

[0062] In summary, this application provides a portable charging device, including a device body, a charging plug, and a first data cable. The charging plug is detachably connected to the device body. The device body is provided with an electrical connector for electrical connection to external devices. One end of the first data cable is connected to the charging plug, and the other end is connected to the device body. The first data cable is electrically connected to the electrical connector and can be stored inside the device body or between the charging plug and the device body. By making the charging plug and device body detachable, this application enhances the functionality of the product and broadens its application scenarios and scope. When not in use, the charging plug is connected to the device body to improve portability. When in use, the charging plug can be detached and plugged into a socket, reducing the weight of the plug. Due to the small size and weight of the charging plug, the probability of the charging plug falling out of the socket is reduced, enhancing the stability of the plugging. It also prevents the plug from blocking other sockets due to excessive size. In addition, the charging plug is the main heat-generating component, and by placing the main heat-generating component away from the device body, the user avoids the unpleasant experience of touching the device body and getting burned.
