[0035] Figures 1 to 3 A portable charging device 1 according to the first embodiment of this application is shown. It can be inserted into a power outlet and connected to a mobile electronic terminal such as a mobile phone via a data cable to charge the mobile electronic terminal. The portable charging device 1 includes a charger 10 and a hook 20. The charger 10 is used to plug into a power outlet to connect to and charge the mobile electronic terminal. The hook 20 is rotatably mounted on the charger 10 and, together with the charger 10, defines a hanging hole 200, allowing it to be worn on clothing, key rings, bag straps, or bag loops.

[0036] like Figure 1 and Figure 3 As shown, in some embodiments, the charger 10 may include a charging body 11 and two prongs 12. The two prongs 12 are spaced apart on the charging body 11 and are used to be inserted into a power socket to connect to a power source for charging electronic mobile terminals.

[0037] The portable charging device 1 is now defined to have a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are mutually perpendicular.

[0038] Then, the two pins 12 can be spaced apart along the first direction X, and are located at one end of the charging body 11 along the third direction Z, and both extend along the third direction Z.

[0039] It should be noted that the pin 12 can be cylindrical, rectangular, or polygonal; no specific limitation is made here.

[0040] In some embodiments, the charging body 11 includes a housing 111, a circuit board (not shown), and at least one charging interface 112. Two prongs 12 are disposed on the housing 111, and a hook 20 is rotatably disposed on the housing 111. The circuit board and the charging interface 112 are both disposed inside the housing 111. A control circuit is arranged on the circuit board, and the charging interface 112 and the two prongs 12 are electrically connected to the control circuit on the circuit board. When the prongs 12 are plugged into a power socket, the user can connect the electronic mobile terminal to the power source by electrically connecting the electronic mobile terminal to the charging interface 112, thereby enabling the charging of the electronic mobile terminal.

[0041] exist Figure 1 In the illustrated embodiment, the outer casing 111 is generally rectangular in shape, having a width direction, a thickness direction, and a height direction. Its width direction is the first direction X, its thickness direction is the second direction Y, and its height direction is the third direction Z.

[0042] Specifically, the housing 111 has at least one through hole 1111, and the charging interface 112 is provided corresponding to the through hole 1111 and is exposed through the through hole 1111. The user can connect the plug of the data cable to the charging interface 112 through the through hole 1111 to achieve electrical connection with the circuit board.

[0043] It should be noted that the charging port 112 and the through hole 1111 can be located at any position on the outer casing 111, and no specific limitation is made here. For example, in Figure 1In the embodiment shown, the charging interface 112 and the through hole 1111 are disposed at one end of the housing 111 along the third direction Z, and are located at the end of the housing 111 away from the hook 20 along the third direction Z, so that the through hole 1111 is exposed, thereby facilitating the user to connect the electronic mobile terminal via a data cable.

[0044] In some other embodiments, the charging interface 112 and the through hole 1111 may also be provided on other walls of the housing 111.

[0045] It should be noted that the number of charging ports 112 and through holes 1111 is not specifically limited here. For example, in Figure 1 In the embodiment shown, there is one charging interface 112 and one through hole 1111.

[0046] In other embodiments, the number of charging interfaces 112 and through holes 1111 can be set to two, three, four, or more. When there are multiple of them, they can be set on the same side wall of the housing 111 or on different side walls of the housing 111. They can be set at intervals or adjacent to each other, and no specific limitation is made here.

[0047] In some other embodiments, the first direction X may also be another direction of the housing 111.

[0048] In other embodiments, the outer shell 111 may be in various shapes such as disc, cylinder, rectangular column, elliptical column, polygonal column, rectangular body, polygonal body, irregular shape, etc., and no specific limitation is made here.

[0049] It should be noted that the charging interface 112 and the control circuit on the circuit board can be implemented using existing technologies. For example, the charging interface 112 can specifically adopt a USB Type-A interface, a USB Type-C interface, a Micro USB interface, a Lightning interface, a MiniUSB interface, etc., and no specific limitation is made here. When there are at least two charging interfaces 112, they can adopt the same type of interface, or at least partially adopt different types of interfaces, and no specific limitation is made here.

[0050] Continue reading Figures 1 to 3 In some embodiments, the outer casing 111 also has stepped surfaces 1112 on its two opposing walls along a certain direction. The distance between the stepped surfaces 1112 of the opposing walls is smaller than the distance between the opposing walls. The two ends of the hook 20 are rotatably disposed at the stepped surfaces 1112 of the opposing walls. Thus, as... Figure 3As shown, the outer wall of the hook 20 at the stepped surface 1112 can be approximately on the same plane as the non-stepped surface 1112 portion of the wall, in order to further improve the aesthetics of the hook-and-loop charging device 1.

[0051] For example in Figure 3 In the illustrated embodiment, the two ends of the hook 20 are rotatably disposed on opposite side walls of the housing 111 along the first direction X, and are disposed at the ends of the side walls along the third direction Z near the pin 12. The ends of the side walls along the third direction Z near the pin 12 are recessed along the first direction X to form stepped surfaces 1112. The two ends of the hook 20 are rotatably disposed on the two stepped surfaces 1112.

[0052] In some other embodiments, the housing 111 may not have a stepped surface, and the two ends of the hook 20 may protrude directly onto the housing 111.

[0053] For example Figure 1 As shown, the hook 20 is rotatably mounted on the charging body 11, and its pivot extends along a first direction. The hook 20 may have a first position and a second position relative to the charger 10.

[0054] When the hook 20 is in the first position relative to the charger 10, the two prongs 12 are on the same plane as the hook 20, and at least part of the prongs 12 are located within the hanging hole 200. At this time, the hook 20 can both be used for hanging and to accommodate the prongs 12, thereby achieving the effect of hiding the prongs 12 and avoiding the problems of prongs protruding and being unsightly and taking up space.

[0055] When the hook 20 is in the second position relative to the charger 10, the two prongs 12 are on different planes from the hook 20. At this time, the prongs 12 are exposed outside the hanging hole 200, which makes it convenient for the user to insert the prongs 12 into the power socket for charging.

[0056] By incorporating a rotatable hook 20, the portable charging device 1 can function as a connecting clip, allowing it to be attached to clothing, key rings, bag straps, or bag loops, thus making it wearable. The rotatable hook 20 can also accommodate the prongs 12 by changing its position, preventing the charger 10 from appearing unsightly due to prongs 12 protruding during non-charging periods.

[0057] It's important to understand that chargers in current technologies are becoming increasingly miniaturized and functional. Most of the prongs in these technologies are exposed. However, some technologies opt for foldable prongs to improve the charger's aesthetics. But chargers with foldable prongs require space inside the casing to accommodate the prongs, resulting in a larger casing size.

[0058] This application, by setting the hook 20 to be in the first position relative to the charger 10, such that at least some of the prongs 12 are located in the hanging hole 200, can both accommodate the prongs 12 and make the portable charging device 1 wearable, and save the space reserved in the outer shell 111 for accommodating the prongs 12, which is conducive to miniaturizing the portable charging device 1 and making it easier to hang the portable charging device 1 on clothing or bags.

[0059] To achieve miniaturization of charging devices, there are currently related technologies that choose to set the charging interface as a USB Type-C interface to save space inside the casing. In some embodiments, when the charging interface 112 of this application selects a relatively small interface type such as the USB Type-C interface in the prior art, the design of the hook 20 and the plug 12 can further facilitate the miniaturization of the clip-on charging device 1, making it easier for users to carry when going out and reducing space occupation.

[0060] In some embodiments, the two ends of the hook 20 are spaced apart along a first direction X and are rotatably disposed on the outer shell 111 of the charging body 11, and are disposed at the end of the charging body 11 along a third direction Z near the plug 12. The hook 20 and the outer shell 111 together define a hanging hole 200 to accommodate the plug 12 in a first position.

[0061] When the hook 20 is in the first position relative to the charger 10, the two prongs 12 are located between the two ends of the hook 20 along the first direction X, and are both located within the hook hole 200.

[0062] Specifically, the hook 20 can be roughly inverted U-shaped, including a first side 201, a second side 202, and a third side 203. The first side 201 and the third side 203 are arranged parallel and spaced apart, with one end of the first side 201 and one end of the third side 203 respectively rotatably connected to the two opposite side walls of the outer casing 111 along the first direction X. The second side 202 extends along the first direction X, and its two ends are respectively connected to the other ends of the first side 201 and the third side 203.

[0063] The position where the first side 201 connects to one of the side walls of the outer casing 111 along the first direction X is approximately located at the central axis of that side wall along the second direction Y. The position where the third side 203 connects to the other side wall of the outer casing 111 along the first direction X is also approximately located at the central axis of that other side wall along the second direction Y.

[0064] like Figure 1As shown, when the hook 20 is in the first position relative to the charger 10, the first side 201, the third side 203 and the two prongs 12 of the hook 20 all extend along the third direction Z, and the two prongs 12 are disposed between the first side 201 and the third side 203 along the first direction X.

[0065] It is important to understand that the arrangement of the charging port 112, circuit board, and other structures inside the outer casing 111 ensures that the projection of the center of gravity of the charging body 11 onto the two side walls along the first direction X of the outer casing 111 is approximately located at the central axis of the two side walls along the second direction Y. By setting the position where the hook 20 connects to these two side walls at the central axis of the side walls along the second direction Y, it is ensured that the line connecting the connection point and the projection of the center of gravity onto the side wall extends along the third direction Z.

[0066] Thus, when the hook 20 is attached to an external object, the charger 10 can automatically rotate relative to the hook 20 under the influence of gravity, positioning the hook 20 in the first position relative to the charger 10. Furthermore, this ensures that when the hook 20 is attached to an object, the prongs 12 can be automatically retracted into the hanging hole 200, preventing them from protruding. This ensures the aesthetic appeal and convenience of the portable charging device 1, further enhancing the user experience.

[0067] Furthermore, one of the two pins 12 is approximately adjacent to the side of the first side 201 closest to the third side 203, and the other pin 12 is approximately adjacent to the side of the third side 203 closest to the first side 201.

[0068] Thus, when the hook 20 is in the first position relative to the charger 10, the two prongs 12 located in the hanging hole 200 can avoid dividing the hanging hole 200 into multiple small spaces, thus preventing it from being used to hang other items.

[0069] Furthermore, the length of the first side 201 along the second direction Y is greater than or equal to the length of the pin 12 along the second direction Y. The length of the third side 203 along the second direction Y is also greater than or equal to the length of the pin 12 along the second direction Y.

[0070] Thus, when the hook 20 is in the first position relative to the charger 10, the two prongs 12 can be completely accommodated in the hook hole 200, avoiding partial protrusion.

[0071] It should be noted that the hook 20 can be a solid structure, and its cross-sectional shape can be circular, semi-circular, rectangular, polygonal, elliptical, semi-elliptical, irregular, or other shapes. Of course, the hook 20 can also be a hollow structure of various shapes. The first side 201, the second side 202, and the third side 203 of the hook 20 can have the same shape and / or dimensions, or at least be at least partially different. No specific limitations are made here.

[0072] It should be noted that the two ends of the hook 20 are rotatably connected to the outer casing 111, which can be achieved by setting a pivot at the end of the first side 201 near the outer casing 111 and the end of the third side 203 near the outer casing 111, respectively. Alternatively, a single pivot extending along the first direction X can be set, so that the ends of the first side 201 and the third side 203 near the outer casing 111 are both rotatably connected to the outer casing 111 via this single pivot. No specific limitation is made here.

[0073] In some other embodiments, at least a portion of the first side 201 and / or the third side 203 may also have a length along the second direction Y that is less than the length of the pin 12 along the second direction Y.

[0074] In some other embodiments, at least one of the two pins 12 may also be spaced apart from the first side 201 or the third side 203 along the first direction X.

[0075] In other embodiments, the hook 20 may also be in the shape of a semi-circular ring, a semi-elliptical ring, a C-shape, an L-shape, an inverted V-shape, an irregular arc, an irregular bend, or other shapes. The two prongs 12 may also be arranged adjacent to the edges of the hook 20 in a non-parallel manner.

[0076] In some other embodiments, when the center of gravity of the portable charging device 1 is located in other positions, the connection position between the hook 20 and the outer shell 111 can be adjusted accordingly.

[0077] like Figure 2 and Figure 3 As shown, in some embodiments, the hanging hole 200 is configured to be openable.

[0078] Specifically, the hook 20 may include a hook 21 connected end to end and a movable buckle 22. The movable buckle 22 has a movable end 221 and a rotating end 222. The movable end 221 is detachably connected to the hook 21, and the rotating end 222 is rotatably disposed, with its pivot extending along a second direction Y to open and close the hook hole 200. The movable buckle 22 may have an open position and a closed position relative to the hook 21.

[0079] like Figure 2 and Figure 3 As shown, when the movable buckle 22 is in the open position relative to the hook 21, the moving end 221 of the movable buckle 22 is spaced apart from the corresponding end of the hook 21, forming an opening between them. Ropes, straps, and buckles of external objects can be inserted into or removed from the hanging hole 200 through this opening.

[0080] like Figure 1As shown, when the movable buckle 22 is in the closed position relative to the hook 21, the moving end 221 of the movable buckle 22 connects with the corresponding end of the hook 21 to close the opening. Ropes, straps, buckles, etc., of external objects will be confined within the hanging hole 200 to enable the hook 20 to be attached to the external object. Alternatively, ropes, straps, buckles, etc., of external objects will be unable to enter the hanging hole 200.

[0081] It should be noted that the movable end 221 of the movable buckle 22 is connected to the corresponding end of the hook 21, which can be understood as follows: Figure 1 The two objects shown are abutting each other along the direction of movement. This can be interpreted as them simply touching without direct contact.

[0082] By setting the hook 20 to include a hook 21 and a movable buckle 22, it is easy to attach the portable charging device 1 to external objects, further improving the user experience.

[0083] exist Figures 1 to 3 In the illustrated embodiment, the hook 21 includes a first part 211 and a second part 212, one end of the first part 211 and one end of the second part 212 being rotatably disposed on the outer shell 111 of the charging body 11. The rotating end 222 of the movable buckle 22 is rotatably disposed at the end of the first part 211 away from the charging body 11, and the moving end 221 is detachably connected to the end of the second part 212 away from the charging body 11.

[0084] Specifically, the first portion 211 is located at the first side 201 of the hook 20, and the second portion 212 is generally L-shaped, partially located at the third side 203 and partially located at the second side 202 of the hook 20. The movable buckle 22 is also generally L-shaped, partially located at the second side 202 and partially located at the first side 201 of the hook 20. The moving end 221 of the movable buckle 22 is located at the second side 202 of the hook 20, so as to be detachably connected to the end of the second portion 212 away from the charging body 11. The rotating end 222 of the movable buckle 22 is located at the first side 201 of the hook 20, so as to be rotatably connected to the end of the first portion 211 away from the charging body 11.

[0085] It should be understood that when the hook 20 is in the first position relative to the charger 10, the two prongs 12 are located between the first side 201 and the third side 203 along the first direction X, and are respectively close to the first side 201 and the third side 203. Therefore, if the moving end 221 of the movable buckle 22 is located at the first side 201 or the third side 203, it will be difficult to form an opening.

[0086] By setting the hook 21 to include a first part 211 and a second part 212, and setting the first and second ends of the movable buckle 22 to be connected between the first part 211 and the second part 212, the moving end 221 of the movable buckle 22 can avoid the position of the pin 12, and thus when the movable buckle 22 is in the open position relative to the hook 21, an effective opening is formed between the movable buckle 22 and the hook 21.

[0087] It should be noted that when the movable buckle 22 is in the open position relative to the hook 21, the movable end 221 of the movable buckle 22 can be located inside the hanging hole 200.

[0088] For example in Figure 3 In the illustrated embodiment, the movable end 221 of the movable buckle 22 and the end of the second part 212 away from the housing 111 are respectively provided with mutually abutting limiting structures. During the process of the movable buckle 22 changing from a closed position to an open position relative to the hook 21, the movable buckle 22 can only rotate counterclockwise, so that when the movable buckle 22 is in the open position relative to the hook 21, the movable end 221 can only be located within the hanging hole 200. During the process of the movable buckle 22 changing from an open position to a closed position relative to the hook 21, when the movable buckle 22 moves clockwise to the closed position, the limiting structure of the movable end 221 abuts against the limiting structure of the end of the second part 212 away from the housing 111, preventing the movable end 221 from continuing to move clockwise.

[0089] Of course, in some other embodiments, when the movable buckle 22 is in the open position relative to the hook 21, the moving end 221 of the movable buckle 22 can also rotate in the opposite direction to be outside the hanging hole 200.

[0090] In some other embodiments, the first portion 211 may also be located partly at the first side 201 and partly at the second side 202.

[0091] In some other embodiments, the second portion 212 may also be located only at the third side 203.

[0092] In some other embodiments, the movable buckle 22 may be located only at the second side 202, or only at the first side 201, or only at the third side 203. Alternatively, the movable buckle 22 may be located partially at the first side 201 and partially at the second side 202.

[0093] In some other embodiments, the hook 21 may also consist of only a single part. The rotating end 222 of the movable buckle 22 is rotatably disposed at the end of the hook 21 away from the housing 111, and the moving end 221 is openably connected to the housing 111. Alternatively, the rotating end 222 of the movable buckle 22 is rotatably disposed on the housing 111, and the moving end 221 is openably connected to the end of the hook 21 away from the housing 111.

[0094] Figures 4 to 7 The second embodiment of the present application shows a portable charging device 1A, which differs from the portable charging device 1 in the first embodiment in that, in this embodiment, the hook 20A is a single structure, in which one of the prongs 12A, together with the hook 20A and the charging body 11A, defines the hanging hole 200A.

[0095] Specifically, one end of the hook 20A is rotatably mounted on the charging body 11A, and the other end is used to connect to one of the plug pins 12A.

[0096] We now define the two pins 12A as pin 121A and pin 122A, respectively. For example... Figure 4 As shown, when the hook 20A is in the first position relative to the charger 10A, the end of the first pin 121A away from the charging body 11A is connected to the end of the hook 20A away from the charging body 11A. The first pin 121A, the hook 20A, and the charging body 11A together define the hanging hole 200A, and the second pin 122A is located inside the hanging hole 200A. When the hook 20A is in the second position relative to the charger 10A, the end of the first pin 121A away from the charging body 11A is spaced apart from the end of the hook 20A away from the charging body 11A.

[0097] Thus, the 12A plug can be used to connect to a power outlet, or it can be used as an accessory for the 20A hook, making the 1A portable charging device more fun and further improving the user experience.

[0098] Furthermore, the hook 20A can be generally bent, and includes a first side 201A, a second side 202A, and a third side 203A. The first side 201A and the third side 203A are arranged parallel to each other and extend along a third direction Z. The second side 202A extends along a first direction X, and its two ends are respectively connected to the other ends of the first side 201A and the third side 203A. The end of the third side 203A away from the second side 202A is rotatably connected to the charging body 11A, and the length of its first side 201A is less than the length of its third side 203A. When the hook 20A is in a first position relative to the charger 10A, the end of the first pin 121A away from the charging body 11A abuts against the end of the first side 201A away from the second side 202A, and the combined shape is approximately an inverted U-shape.

[0099] It should be noted that the sum of the length of the first pin 121A along the third direction Z and the length of the first side 201A of the hook 20A along the third direction Z can be greater than the length of the third side 203A along the third direction Z. Thus, when the hook 20A is in the first position relative to the charger 10A, a portion of the first pin 121A can overlap with a portion of the first side 201A in the third direction Z, preventing objects located within the hanging hole 200A from slipping out through the gap between the first pin 121A and the hook 20A.

[0100] In some other embodiments, the first pin 121A may also be disposed non-overlapping with the first side 201A in the third direction Z. When the hook 20A is in the first position relative to the charger 10A, the end of the first pin 121A away from the charging body 11A may also be disposed with the end of the first side 201A away from the second side 202A in the third direction Z.

[0101] like Figure 5 As shown, in some embodiments, the first pin 121A is rotatably disposed on the charging body 11A to switch the hanging hole 200A on and off. The pivot of the first pin 121A can extend along the second direction Y.

[0102] The first pin 121A may have a third position and a fourth position relative to the charging body 11A.

[0103] like Figure 4 and Figure 6 As shown, when the hook 20A is in the first position relative to the charger 10A and the first pin 121A is in the third position relative to the charging body 11A, the end of the first pin 121A away from the charging body 11A is connected to the end of the first side 201A of the hook 20A away from the second side 202A. The first pin 121A, the hook 20A and the charging body 11A together define the hanging hole 200A.

[0104] like Figure 5 As shown, when the hook 20A is in the first position relative to the charger 10A and the first pin 121A is in the fourth position relative to the charging body 11A, the end of the first pin 121A away from the charging body 11A is spaced apart from the end of the first side 201A of the hook 20A away from the second side 202A, forming an opening between them. Ropes, straps, and buckles of external objects can be threaded through this opening into the hanging hole 200A, or removed from the hanging hole 200A.

[0105] This further enhances the usability of the portable charging device 1A, thereby improving the user experience. Users can freely choose how to attach the portable charging device 1A to other items. The portable charging device 1A can open and close the hanging hole 200A by rotating the hook 20A to hang other items within the hanging hole 200A, or it can open and close the hanging hole 200A by rotating the first pin 121A.

[0106] It should be noted that when the first pin 121A is in the fourth position relative to the charging body 11A, the end of the first pin 121A that is away from the charging body 11A is as follows: Figure 5 As shown, it is located between the first side 201A and the third side 203A along the first direction X, or it can be located on the side of the first side 201A away from the third side 203A along the first direction X. No specific limitation is made here.

[0107] In some embodiments, the end of the hook 20A that connects to the first pin 121A further defines a clearance groove 211A. When the hook 20A is in a first position relative to the charger 10A and the first pin 121A is in a third position relative to the charging body 11A, the end of the first pin 121A away from the charging body 11A is located in the clearance groove 211A.

[0108] Specifically, the clearance groove 211A is located at the end of the first side 201A away from the second side 202A, and is located on the side of the first side 201A facing the third side 203A.

[0109] like Figure 4 and Figure 6 As shown, when the hook 20A is in the first position relative to the charger 10A and the first pin 121A is in the third position relative to the charging body 11A, the end of the first pin 121A away from the charging body 11A is at least partially located in the relief groove 211A so as to connect with the end of the first side 201A away from the second side 202A.

[0110] During the process of the first pin 121A rotating relative to the charging body 11A from the third position to the fourth position, the first pin 121A... Figures 4 to 6 In the embodiment shown, it rotates counterclockwise to disengage from the relief groove 211A.

[0111] like Figure 5 As shown, when the hook 20A is in the first position relative to the charger 10A and the first pin 121A is in the fourth position relative to the charging body 11A, the end of the first pin 121A away from the charging body 11A is located outside the clearance groove 211A and is located between the first side 201A and the third side 203A along the first direction X.

[0112] Further reading Figure 7 The clearance groove 211A has two opposing groove walls along the second direction Y, which are used to limit the first pin 121A.

[0113] When a user wants to rotate the hook 20A from the first position to the second position, they must first rotate the first pin 121A from the third position to the fourth position so that the end away from the charging body 11A can be dislodged from the relief groove 211A, thus releasing the degree of freedom along the second direction Y, so that the hook 20A can be rotated from the first position to the second position.

[0114] This improves the stability of the hanging hole 200A when it is closed. When the portable charging device 1A is attached to other items, the clearance slot 211A also prevents the buckle 20A from rotating accidentally, thereby preventing the portable charging device 1A from being accidentally disassembled from other items due to the hanging hole 200A opening accidentally, and preventing the portable charging device 1A from being lost.

[0115] In some other embodiments, the clearance groove 211A may also be provided through both sides opposite to each other along the second direction Y.

[0116] In some other embodiments, when the first pin 121A is in the fourth position relative to the charging body 11A, the end of the first pin 121A away from the charging body 11A is located along the first direction X on the side of the first side 201A away from the third side 203A, and the clearance groove 211A may also be located on the side of the first side 201A away from the third side 203A.

[0117] In some embodiments, the groove shape of the clearance groove 211A may be adapted to the shape of the first pin 121A.

[0118] For example in Figure 7 In the illustrated embodiment, the cross-section of the clearance groove 211A perpendicular to the third direction Z and the cross-section of the first pin 121A perpendicular to the third direction Z are both rectangular. When the first pin 121A is in the third position relative to the charging body 11A, the exposed sidewall of the first pin 121A smoothly engages with the hook 20A to improve the aesthetics of the appearance and the smoothness of the hole wall of the hanging hole 200A.

[0119] In other embodiments, the shape of the clearance groove 211A may differ from the shape of the first pin 121A. For example, the clearance groove 211A may have a semi-circular cross-section perpendicular to the third direction Z, while the first pin 121A may have a circular cross-section perpendicular to the third direction Z. Alternatively, the clearance groove 211A may have a rectangular cross-section perpendicular to the third direction Z, while the first pin 121A may have a circular cross-section perpendicular to the third direction Z.

[0120] In some other embodiments, when the first pin 121A is in the third position relative to the charging body 11A, the first pin 121A may also be partially located inside the clearance groove 211A and partially located outside the clearance groove 211A.

[0121] Figure 8 and Figure 9 The attached charger 1B according to the third embodiment of this application is shown. The main difference between it and the attached charger 1B in the first embodiment is that, in this embodiment, the charger 10B may also include at least one data line (not shown in the figure).

[0122] Specifically, the outer casing 111B is generally disc-shaped, with two opposing circular walls along its thickness direction. The first direction X is its thickness direction, and the two opposing circular walls are parallel to the plane defined by the second direction Y and the third direction Z. The charging interface 112B and the through hole 1111B are disposed on one of the circular walls of the disc-shaped outer casing 111B. The two ends of the hook 20B are rotatably disposed on the two opposing circular walls of the outer casing 111B, and are located at the ends of the circular walls along the third direction Z near the pin 12B.

[0123] The housing 111B may define at least one receiving cavity 1115B for storing a data cable.

[0124] By designing this data cable, the data cable and charger 10B can be integrated. When going out, users no longer need to carry separate chargers and data cables; they only need to carry the clip-on charging device 1B constructed in this application, thereby further improving the convenience and functionality of users' travel.

[0125] In some embodiments, a cylindrical inner shell 113B may be provided inside the outer shell 111B. The inner shell 113B is coaxially arranged with the outer shell 111B and divides the disc-shaped space inside the outer shell 111B into two coaxially fitted chambers. The inner cylindrical chamber is used to house the circuit board and the charging interface 112B, while the outer annular chamber is the receiving cavity 1115B, which is used to house the data cable.

[0126] Furthermore, such as Figure 9 As shown, the housing 111B also defines at least one cable passage hole, which communicates with both the receiving cavity 1115B and the external space. The end of the data cable is retractably inserted into the cable passage hole.

[0127] Specifically, the data cable may include a first end and a second end, wherein the first end is used to connect to a user's electronic mobile terminal, and the second end is used to connect to another electronic mobile terminal or a charger, so as to facilitate data transmission or charging of the electronic mobile terminal.

[0128] For example in Figure 9 In the illustrated embodiment, the housing 111B is provided with a first cable pass-through hole 1113B and a second cable pass-through hole 1114B. The first cable pass-through hole 1113B and the second cable pass-through hole 1114B are respectively located on opposite sides of the housing 111B along the second direction Y. The first end of the data cable is retractably inserted into the first cable pass-through hole 1113B, and the second end of the data cable is retractably inserted into the second cable pass-through hole 1114B.

[0129] By allowing the two ends of the data cable to be retractably threaded through different cable guide holes, the usage of the data cable can be enriched.

[0130] For example, when using the portable charging device 1B, a user can choose to connect the second end to the charging interface 112B, insert the pin 12B into the power socket, and electrically connect the first end of the data cable to the electronic mobile terminal, thereby charging the electronic mobile terminal. Alternatively, the user can choose to connect the second end to another charger or mobile storage device, connect the first end to the electronic mobile terminal, and connect another electronic mobile terminal to the charging interface 112B via a separate data cable, thereby charging at least two electronic mobile terminals. Yet another example is that the user can choose to connect both ends of the data cable to different electronic mobile terminals to achieve data transfer between different electronic mobile terminals.

[0131] By allowing the data cable to be retractably threaded through the cable guide hole, users can easily pull out the data cable located in the receiving cavity 1115B to flexibly adjust the length of the data cable exposed in the outer casing 111B.

[0132] It should be noted that the data cable can be retractably threaded through the cable guide hole, which can be achieved using existing technology and is not specifically limited here. For example, a winding structure such as a coil can be provided in the receiving cavity 1115B, along with a retraction structure such as a coil spring or a clockwork mechanism. The data cable is wound on the winding structure, and the retraction structure can generate a preload force based on the pulling force on the end of the data cable. This preload force can automatically retract the data cable into the receiving cavity 1115B after the external force is removed.

[0133] In some other embodiments, the first wire hole 1113B and the second wire hole 1114B may be spaced apart in other directions, or respectively disposed on adjacent or the same wall of the housing 111B.

[0134] In some other embodiments, the outer casing 111B may have only one through hole for the first end of the data cable to pass through. The second end of the data cable can be directly fixed inside the outer casing 111B and electrically connected to the circuit board inside the inner casing 113B. Users can charge their electronic mobile terminals by connecting the first end of the data cable.

[0135] In some other embodiments, the number of data cables and housing cavities 1115B may be two or more to further improve the integration of the clip-on charging device 1B.

[0136] In some other embodiments, the data cable may also be fixed inside a cable pass-through hole so that the length of the data cable outside the housing 111B is constant.

[0137] In other embodiments, the inner shell 113B may also be in other shapes such as polygonal tubular or elliptical tubular.

[0138] In some other embodiments, the charging interface 112B and the through hole 1111B may also be provided on other walls of the housing 111B.

[0139] It should be noted that the first and second ends of this data cable can use existing port types. For example, the first end can be at least one of USB Type-A, USB Type-C, Micro USB, Lightning, Mini USB, etc., and the second end can also be at least one of USB Type-A, USB Type-C, Micro USB, Lightning, Mini USB, etc., without any specific limitation.

[0140] Understandably, the above-mentioned technical features can be used in any combination without restriction.

[0141] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this application's patent. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of this application, and can also make several modifications and improvements, all of which fall within the protection scope of this application. Therefore, any equivalent transformations and modifications made within the scope of the claims of this application should be covered by the claims of this application.
