[0023] Before describing the embodiments in detail, it should be understood that the present application is not limited to the detailed structures or element arrangements described hereinafter or in the accompanying drawings of the present application. The present application can be implemented in other ways. Moreover, it should be understood that the terms and phrases used herein are only for descriptive purposes and should not be construed as limiting. The terms "including", "comprising", "having" and the like used herein are intended to include the matters listed hereinafter, their equivalents and other additional matters. In particular, when describing "a certain element", the present application does not limit the number of such elements to one, and multiple elements can also be included.

[0024] Please refer to Figures 1 to 4As shown in the figure, the present application provides a mobile power supply 10, which can be used to charge electronic devices such as mobile phones and tablet computers. The mobile power supply 10 includes a housing 12, a telescopic cable module 14, a circuit main board 16, and a power supply component. Among them, the housing 12 forms a cavity 18, and the telescopic cable module 14, the circuit main board 16, and the power supply component are all arranged in the cavity 18. The telescopic cable module 14 and the power supply component are respectively electrically connected to the circuit main board 16. The power supply component is located on one side of the cavity 18, and the circuit main board 16 and the telescopic cable module 14 are located on the other side of the cavity 18. The circuit main board 16 and the telescopic cable module 14 are arranged side by side in the cavity 18, that is, the circuit main board 16 is located on the circumferential side of the telescopic cable module 14. Among them, the circumferential side of the telescopic cable module 14 refers to the area outside the side of the telescopic cable module 14, that is, the part where the circuit main board 16 and the telescopic cable module 14 do not overlap in the thickness direction of the housing 12. By arranging the circuit main board 16 on the circumferential side of the telescopic cable module 14, the present application avoids the stacking of the circuit main board 16 in the thickness direction, thereby reducing the overall thickness of the mobile power supply 10, and further reducing the overall volume of the mobile power supply 10, which brings convenience to the user's use and carrying.

[0025] Among them, the telescopic cable module 14 is arranged in the housing 12. Specifically, the telescopic cable module 14 includes a data cable 20, and the data cable 20 is telescopically disposed through the housing 12. Therefore, a part of the data cable 20 is located in the cavity 18 and another part is located outside the housing 12, that is, a part of the telescopic cable module 14 is located in the cavity 18 and another part is located outside the housing 12. The above-mentioned circuit main board 16 and the telescopic cable module 14 are arranged side by side in the cavity 18, which means that the part of the telescopic cable module 14 located in the cavity 18 is arranged side by side with the circuit main board 16.

[0026] In this embodiment, the housing 12 is integrally in a cuboid structure. Therefore, the housing 12 has a length direction L, a width direction W, and a thickness direction D, and the length direction L, the width direction W, and the thickness direction D are perpendicular to each other. The telescopic cable module 14 and the circuit main board 16 are arranged side by side in the width direction W of the housing 12, and the telescopic cable module 14 and the circuit main board 16 are arranged close to each other. The power supply component is arranged side by side with the telescopic cable module 14 and the circuit main board 16 in the length direction L of the housing 12. In other embodiments, the telescopic cable module 14 and the circuit main board 16 can also be arranged side by side in the length direction L, the diagonal direction, or other inclined directions of the housing 12, as long as the circuit main board 16 is located on the circumferential side of the telescopic cable module 14.

[0027] In the illustrated embodiment, the telescopic wire module 14 is generally cylindrical as a whole, or at least one side of the telescopic wire module 14 adjacent to the circuit main board 16 is arc-shaped. Correspondingly, a relief portion 22 is provided on the side of the circuit main board 16 close to the telescopic wire module 14, and the relief portion 22 is adapted to the telescopic wire module 14. In other words, a notch for avoiding the telescopic wire module 14 is provided on the side of the circuit main board 16 close to the telescopic wire module 14, so that a relief portion 22 is formed on the side of the circuit main board 16 close to the telescopic wire module 14. Such an arrangement can make the circuit main board 16 and the telescopic wire module 14 arranged adjacent to and side by side, with strong compactness, saving the space in the cavity 18 and reducing the length of the mobile power supply 10 in the width direction W. In this embodiment, the telescopic wire module 14 is generally circular as a whole. Therefore, the relief portion 22 is designed to be arc-shaped to match the arc-shaped outer wall of the telescopic wire module 14. In other embodiments, according to the outer wall shape of the telescopic wire module 14, the relief portion 22 can also be designed into other adapted shapes, and the present application does not limit the shape of the relief portion 22.

[0028] More specifically, the telescopic wire module 14 includes a rotating base 24, a fixed circuit board 26, a rotating circuit board 28 and an outer cover 30. The rotating base 24, the fixed circuit board 26 and the rotating circuit board 28 are all arranged inside the outer cover 30. Among them, the outer cover 30 is fixedly connected to the housing 12, for example, by screws or snap-fits, for easy disassembly and maintenance. The outer cover 30 includes a first cover body 30a and a second cover body 30b connected in butt joint, and the first cover body 30a and the second cover body 30b are detachably connected, for example, by snap-fits or screws, for easy disassembly and maintenance. A rotating shaft is provided at the bottom of the second cover body 30b, and the rotating base 24 is rotatably sleeved on the rotating shaft. The axial direction of the rotating shaft is parallel to the thickness direction D of the housing 12. The rotating base 24 includes a bottom plate 32 and a turntable 34 connected to the bottom plate 32. The turntable 34 and the bottom plate 32 are, for example, integrally formed structures. The rotating circuit board 28 is fixedly supported on the rotating base 24. For example, the rotating circuit board 28 is fixedly supported on the turntable 34 to rotate together with the rotating base 24. The rotating circuit board 28 is fixedly connected to the turntable 34, for example, by bonding. The rotating circuit board 28 and the rotating base 24 jointly enclose a wire winding space 36, and the data line 20 is wound around the outside of the turntable 34 and stored in the wire winding space 36.

[0029] The data cable 20 has a winding connection end and a telescopic connection end 20b opposite to each other. The data cable 20 is wound outside the turntable 34 through the winding connection end, and the winding connection end is electrically connected to the rotating circuit board 28. For example, the winding connection end is fixed to the rotating circuit board 28 by copper wire welding, so as to achieve electrical connection between the two. The telescopic connection end 20b protrudes out of the winding space 36 and is telescopically inserted into the housing 12. The telescopic connection end 20b is provided with a charging connector 38, which is located outside the housing 12 and is used to connect to an electronic device to charge it, or to connect to an external power source to charge the mobile power supply 10. A storage portion 40 for storing the charging connector 38 is provided on the side wall of the housing 12. A through hole is provided at the bottom of the storage portion 40 for the data cable 20 to extend and pass through. The storage portion 40 is, for example, a groove structure. When the data cable 20 is in use, it can be stretched to a certain length outside the housing 12 according to actual needs. When stretched, the rotating seat 24 is driven to rotate. When the data cable 20 is not in use, the data cable 20 can be wound outside the turntable 34 and stored in the winding space 36. At the same time, the charging connector 38 is stored in the storage portion 40. Preferably, the storage portion 40 is located on the side of the housing 12 close to the telescopic cable module 14 to facilitate the pulling of the data cable 20.

[0030] Preferably, the turntable 34 is an internal hollow structure, and an elastic reset member (not shown) is provided inside the turntable 34. The elastic reset member is, for example, a clockwork spring. The elastic reset member is used to apply an elastic bias to the turntable 34 to rotate it toward the initial rotation position, so that the rotating seat 24 can automatically reset after rotation, and further the data cable 20 can be automatically wound around the outside of the turntable 34 for storage when not in use.

[0031] The fixed circuit board 26 is located on the side of the rotating circuit board 28 away from the rotating seat 24. The fixed circuit board 26 is fixedly connected to the outer cover 30, for example, fixed by screws, so as to facilitate disassembly and maintenance. The fixed circuit board 26 and the rotating circuit board 28 are arranged at a distance and are electrically connected. In the illustrated embodiment, a conductive terminal (not shown) is provided on the side of the fixed circuit board 26 facing the rotating circuit board 28, and a conductive track 46 is provided on the side of the rotating circuit board 28 facing the fixed circuit board 26. The conductive terminal can be slidably matched with the conductive track 46, so that the rotating circuit board 28 can maintain electrical connection with the fixed circuit board 26 regardless of whether it is stationary or rotating.

[0032] In the illustrated embodiment, the fixed circuit board 26 is electrically connected to the circuit main board 16. Specifically, the fixed circuit board 26 is protruded toward one side of the circuit main board 16 to form an externally protruding conductive connection portion 48. The circuit main board 16 is provided with a conductive connection seat 50 corresponding to the externally protruding conductive connection portion 48. The conductive connection seat 50 is provided close to the avoidance portion 22. The externally protruding conductive connection portion 48 is located above the conductive connection seat 50. The externally protruding conductive connection portion 48 is conductively connected to the conductive connection seat 50. For example, a plug is provided on the conductive connection seat 50, and a socket is provided on the externally protruding conductive connection portion 48. The plug is plugged into the socket to achieve conductive connection.

[0033] Preferably, since the thickness of the telescopic wire module 14 in the outer shell 12 is the largest, for safety considerations, the thickness of the power supply element is set to be less than or equal to the thickness of the telescopic wire module 14. Such a setting can prevent the power supply element from alone bearing the impact force when the mobile power supply 10 is externally impacted, thus avoiding danger. Preferably, the thickness of the power supply element is less than the thickness of the telescopic wire module 14, leaving an expansion space for the power supply element to ensure the safety of the power supply element.

[0034] In the illustrated embodiment, the power supply element includes two power supply units 52. The power supply unit 52 is, for example, a rechargeable battery. The two power supply units 52 are stacked in the thickness direction D of the outer shell 12 and are connected in series. In other embodiments, the number of the power supply units 52 can also be set to other quantities, such as one or more than two. The present application does not limit the number of the power supply units 52. The thickness after multiple power supply units 52 are stacked together needs to be less than or equal to the thickness of the telescopic wire module 14. Among them, the power supply unit 52 includes a tab (not shown in the figure) located on the side close to the circuit main board 16 and the telescopic wire module 14. A protective member 54 is provided outside the tab. The protective member 54 is used to protect the tab and can also play a role in safety insulation. The protective member 54 is, for example, a block structure. The tab is electrically connected to the circuit main board 16 through a wire. For example, the wire passes through the protective member 54 and is welded to the circuit main board 16. The power supply element is fixedly installed in the cavity 18. For example, double-sided tapes 62 are pasted on the opposite sides in the thickness direction of the power supply element. One side of the double-sided tape 62 is adhered to the power supply element, and the other side is adhered to the corresponding inner wall of the outer shell 12, thereby realizing the installation and fixation of the power supply element.

[0035] Preferably, the outer shell 12 is further provided with an indicator light 56, a button 58, and at least one charging interface 60 that are electrically connected to the circuit main board 16. Among them, the charging interface 60 and the button 58 are arranged on the side wall of the outer shell 12, and the indicator light 56 is arranged on the end face of the outer shell. The charging interface 60 can be used to connect an electronic device to charge it or connect an external power supply to charge the power supply element. The button 58 can be used to turn on / off the mobile power supply 10, and the indicator light 56 can be used to prompt the power state of the mobile power supply 10. Further, the circuit main board 16 is provided with a connection seat 70. The connection seat 70 is located on the side of the circuit main board 16 away from the telescopic wire module 14 to be close to the side of the outer shell 12. The connection seat 70 is correspondingly arranged with the charging interface 60. For example, the connection seat 70 is arranged directly opposite to the charging interface 60. The indicator light 56, the button 58, and the charging interface 60 are all arranged around the connection seat 70 and are respectively electrically connected to the connection seat 70. The outer shell 12 includes a shell body part 12a and a shell cover 12b covering the opening end of the shell body part 12a. The shell cover 12b is detachably connected to the shell body part 12a, for example, detachably fixed by means of a buckle or the like, so as to facilitate disassembly, assembly, and maintenance.

[0036] In summary, the present application provides a mobile power supply, which includes a housing having a cavity, a telescopic wire module, a circuit main board and a power supply component disposed in the cavity. The telescopic wire module and the power supply component are respectively electrically connected to the circuit main board. The power supply component is located on one side of the cavity, and the circuit main board and the telescopic wire module are located on the other side of the cavity, and the circuit main board is located on the circumferential side of the telescopic wire module. By arranging the circuit main board side by side on the circumferential side of the telescopic wire module, the present application avoids the accumulation of the circuit main board in the thickness direction of the housing, thereby reducing the overall thickness of the mobile power supply, and further reducing the overall volume of the mobile power supply, which brings convenience to the user's use and carrying.
