DETAILED DESCRIPTION

[0041] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which preferred embodiments of the present invention are shown.

[0042] In the description of the embodiments of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0043] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0044] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0045] like Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 As shown, in one embodiment, a multifunctional mobile power supply 1 includes a shell 10, an energy storage component, a magnetic ring 20 and a charging component. The energy storage component includes a battery 31 and a circuit board 32. The battery 31 and the circuit board 32 are both arranged in the shell 10, and the circuit board 32 is electrically connected to the battery 31. The magnetic ring 20 is arranged on the inner wall of the shell 10. The magnetic ring 20 is used to magnetically fix the charging device. The charging component includes a charging coil 41 and a plurality of charging plugs 42. The charging coil 41 and the charging plugs 42 are both electrically connected to the circuit board 32, and the charging coil 41 is arranged on the inner wall of the shell 10, and the charging coil 41 is located in the magnetic ring 20. One end of each charging plug 42 is electrically connected to the circuit board 32, and the other end of each charging plug 42 is embedded in the outer wall of the shell 10.

[0046] It should be noted that the housing 10 includes an upper cover 11, a middle frame 12, and a lower cover 13. The upper cover 11 and the lower cover 13 are respectively arranged on the two side surfaces of the middle frame 12. The battery 31 is arranged in the middle frame 12. The circuit board 32 is arranged in the middle frame 12 and is located between the battery 31 and one of the side surfaces of the middle frame 12. The battery 31 and the circuit board 32 are electrically connected. Furthermore, a boss 111 is arranged on the outer surface of the upper cover 11, and a groove 112 is opened on the upper cover 11. The groove 112 is annular and extends from the inner side surface of the upper cover 11 to the inside of the boss 111. Furthermore, a circular groove 113 is also opened on the upper cover 11. The circular groove 113 extends from the inner side surface of the upper cover 11 to the inside of the boss 111. The diameter of the circular groove 113 is smaller than the diameter of the groove 112, so that the circular groove 113 can be located in the groove 112. Furthermore, the magnetic ring 20 is disposed in the groove 112, and the charging coil 41 is disposed in the circular groove 113. Since both the groove 112 and the circular groove 113 extend from the inner side of the upper cover 11 into the boss 111, the magnetic ring 20 and the charging coil 41 are both located on the inner side of the upper cover 11 and within the boss 111. Furthermore, since the boss 111 is disposed on the outer side of the upper cover 11, the boss 111 forms a raised structure relative to the outer side of the upper cover 11. Since both the magnetic ring 20 and the charging coil 41 are located within the boss 111, the magnetic ring 20 is more firmly attached to the charging device, thereby allowing the charging coil 41 to be closer to the charging device, thereby improving the charging effect of the charging coil 41. Furthermore, as the charging device is continuously updated and iterated, the camera module on the charging device becomes more and more prominent, making the height difference between the camera module on the charging device and the wireless charging module larger and larger. Thus, a boss 111 is provided on the upper cover 11, which can avoid the area of ​​the camera module on the charging device, and the magnetic ring 20 and the charging coil 41 are both located in the boss 111, so that the magnetic ring 20 and the charging coil 41 can be well fitted with the wireless charging area on the charging device, so as to avoid the multi-functional mobile power supply 1 being unable to fully fit with the charging device due to the protrusion of the camera module area.

[0047] like Figure 1 、 Figure 3 As shown, in one embodiment, a ring groove is provided on one side surface of the boss 111 away from the groove 112, and the charging component also includes an anti-slip gasket 43, which is arranged in the ring groove. For example, the anti-slip gasket 43 is adhered to the ring groove by glue, and the thickness of the anti-slip gasket 43 is greater than the depth of the ring groove.

[0048] It should be noted that when the anti-slip gasket 43 is stuck in the annular groove, the anti-slip gasket 43 can protrude relative to the annular groove. In this way, when one side of the anti-slip gasket 43 can be fixed in the annular groove, the other side of the anti-slip gasket 43 can contact the charging device. Furthermore, since the groove 112 and the annular groove are both opened on the upper cover 11, and the groove 112 and the annular groove are respectively located on the outer side and the inner side of the upper cover 11 that are aligned with each other, the anti-slip gasket 43 and the magnetic ring 20 are also in a relatively aligned state. When the charging device is placed on the anti-slip gasket 43, the magnetic ring 20 can adsorb the charging device so that it is close to the anti-slip gasket 43. At the same time, the anti-slip gasket 43 can prevent the charging device from sliding during the charging process.

[0049] like Figure 3 、 Figure 6 As shown, in one embodiment, one end of each charging cable 42 is electrically connected to the circuit board 32 , and the other end of each charging cable 42 is embedded in the outer wall of the housing 10 .

[0050] It should be noted that each charging cable 42 has a clamping block 421 at one end and a connector 422 at the other end. The clamping block 421 is located on one side of the middle frame 12. One end of the wire in the charging cable 42 is electrically connected to the circuit board 32 via the clamping block 421, and the other end of the wire is electrically connected to the connector 422. Furthermore, each connector 422 has a different structure. For example, one connector 422 is a Type-C connector 422, and another is a Lightning connector 422. Furthermore, a plurality of wire grooves are provided on the outer surface of the middle frame 12, and each wire groove corresponds to each charging plug 42 one by one, and the wire grooves extend from one side surface of the middle frame 12 to the other adjacent side surface of the middle frame 12. A connector 422 groove is provided at one end of each wire groove away from each card block 421, and the connector 422 grooves are all connected to each wire groove. When each charging plug 42 is embedded in each wire groove, each connector 422 can be accommodated in the connector 422 groove, and each connector 422 is stuck in the position where the connector 422 groove is connected to each wire groove. The width of each wire groove is smaller than the width of each charging plug 42. In this way, each charging plug 42 cannot fall off naturally after being embedded in each plug groove.

[0051] like Figure 1 、 Figure 6 、 Figure 12 As shown, in one embodiment, a USB hole and a Type-c hole are further provided on the middle frame 12 , the USB hole is aligned with the USB interface on the circuit board 32 , and the Type-c hole is aligned with the Type-c interface on the circuit board 32 .

[0052] It should be noted that the USB port and the Type-C port are both located on the side of the middle frame 12 away from the connector 422 slot. Since the circuit board 32 is located between the battery 31 and the middle frame 12, the USB port and the Type-C port can be aligned with the USB interface and the Type-C interface on the circuit board 32. In this way, the user can electrically connect to the multi-functional mobile power supply 1 of the present application through wires of different connectors 422, so that the multi-functional mobile power supply 1 of the present application can meet more charging methods to improve the charging needs of users.

[0053] like Figures 10 to 13 As shown, in one embodiment, the charging assembly further includes a swivel seat 44, an insert block 45 and two conductive sheets 46. The swivel seat 44 is disposed on the housing 10, and the two conductive sheets 46 are disposed on the swivel seat 44. Both conductive sheets 46 are electrically connected to the circuit board 32. The insert block 45 is rotatably disposed on the swivel seat 44, and both ends of the insert block 45 are respectively in contact with the two conductive sheets 46.

[0054] It should be noted that the rotating base 44 has two slots 441, each of which has a cylindrical inner wall at one end. The two conductive plates 46 also have circular holes at one end. When the two conductive plates 46 are located in the slots 441, the circular holes on the two conductive plates 46 can be locked into the two cylindrical holes, preventing the two conductive plates 46 from sliding out of the rotating base 44. Furthermore, the ends of the two conductive plates 46 away from the circular holes are provided with beveled portions 461, and the orientation of the two beveled portions 461 aligns with the openings of the slots 441, forming two spring-like structures on the rotating base 44. The two beveled portions 461 abut against the insert 45, and the ends of the two conductive plates 46 away from the beveled portions 461 are electrically connected to the circuit board 32. In this way, the insert 45 can be electrically connected to the circuit board 32 through the two conductive plates 46.

[0055] like Figures 1 to 4 、 Figure 6 、 Figure 8 As shown, in one embodiment, the plug block 45 includes an axis block 451 and two electrode pieces 452. The axis block 451 is rotatably set on the rotating seat 44. The two electrode pieces 452 are respectively passed through the two ends of the axis block 451, and the two electrode pieces 452 are respectively abutted against the bevel portions 461 of the two conductive pieces 46.

[0056] It should be noted that the rotating base 44 is also provided with a support column, and the support column is located between the two slots 441. The shaft block 451 is rotatably mounted on the support column. One end of the two electrode sheets 452 is respectively inserted through one side of the shaft block 451 at both ends of the shaft block 451 and extends from the other side of the shaft block 451. One end of the two electrode sheets 452 extending from the other side of the shaft block 451 respectively abuts the two beveled portions 461. Furthermore, the two electrode sheets 452 are arranged in parallel and spaced apart.

[0057] like Figure 8 As shown, in one embodiment, both ends of the shaft block 451 tend to be heart-shaped structures, with the sharp corners at right angles, and the two electrode sheets 452 are both arranged at both ends of the shaft block 451 along one of the sides of the right angle, and the ends of the two electrode sheets 452 extending from the other side of the two ends of the shaft block 451 are both at a 45-degree angle to the side of the shaft block 451 away from the right angle.

[0058] It should be noted that a receiving groove is provided on the middle frame 12, and one end of the two electrode sheets 452 connected to the shaft block 451 is located in the middle frame 12, and the ends of the two electrode sheets 452 away from the shaft block 451 pass through the middle frame 12 and are located in the receiving groove. Further, when the two electrode sheets 452 are both accommodated in the receiving groove, the side surfaces of the two electrode sheets 452 on the shaft block 451 that are parallel to the right angle will be attached to the two conductive sheets 46, and the beveled portions 461 on the two conductive sheets 46 will push the two electrodes 452 to the top respectively. The two electrode sheets 452 are arranged to keep the two electrode sheets 452 accommodated in the receiving groove. When the two electrode sheets 452 are rotated and stood up through the shaft block 451, the two electrode sheets 452 and the shaft block 451 are rotated as the axis, so that the two beveled portions 461 push the two electrode sheets 452 to keep them in an upright state. In this way, when it is necessary to supplement the power supply 1 of the present application with electric energy, the plug block 45 can be stood up so that the multifunctional mobile power supply 1 can be plugged into the power supply.

[0059] like Figures 2 to 3 、 Figures 9 and 10 As shown, in one embodiment, the multifunctional mobile power supply 1 further includes a cover 50 and a bracket 60. The cover 50 is arranged on the inner side wall of the shell 10. The bracket 60 slides on the cover 50, and the bracket 60 is located between the shell 10 and the cover 50. A corner portion 62 is provided on the bracket 60. When the bracket 60 is slid by an external force to drive the corner portion 62 away from the cover 50, the corner portion 62 and the shell 10 jointly support the charging device.

[0060] It should be noted that the cover plate 50 is disposed on the lower cover 13 and is located near one of the side edges of the lower cover 13. For example, the cover plate 50 is screwed to the lower cover 13. The bracket 60 is slidably disposed on the cover plate 50 and is located between the lower cover 13 and the cover plate 50. Furthermore, the cover plate 50 is provided with two slide grooves, and the bracket 60 is provided with two sliders 61. The two sliders 61 are respectively slidably disposed in the two slide grooves, and both sliders 61 are located between the cover plate 50 and the lower cover 13. The lower cover 13 is provided with a notch, and the notch is connected to one of the sides of the lower cover 13. When the two sliders 61 on the bracket 60 slide in the two slide grooves, the bracket 60 can slide away from the notch or slide into the notch relative to the lower cover 13.

[0061] like Figures 10 and 11 As shown, in one embodiment, a buckle column is provided on the slider 61, and a buckle groove is provided on the lower cover 13, and the buckle column is engaged with the buckle groove.

[0062] It should be noted that a latch post is provided on the side of the slider 61 facing the lower cover 13, and a first latch slot, a second latch slot, a third latch slot, and a fourth latch slot are provided on the side of the lower cover 13 facing the slider 61. The first and second latch slots are located on one side of the slot, while the third and fourth latch slots are located on the other side of the slot. For ease of description, the latch posts on the two sliders 61 are referred to as the first latch post and the second latch post, respectively. When the bracket 60 is slid out of the slot relative to the cover plate 50 under external force, the bracket 60 drives the first and second latch posts to slide out of the first and third latch slots, respectively, and engage the first and second latch posts into the second and fourth latch slots, respectively. When the bracket 60 is slid into the slot relative to the cover plate 50 under external force, the bracket 60 drives the first and second latch posts to slide out of the second and fourth latch slots, respectively, and engage the first and second latch posts into the third and fourth latch slots, respectively. This allows the bracket 60 to extend or fit relative to the lower cover 13.

[0063] like Figure 3 、 Figures 10 and 11 As shown, in one embodiment, a corner portion 62 is provided at one end of the bracket 60 away from the two sliders 61. When the bracket 60 slides under external force to drive the corner portion 62 away from the cover 50, the corner portion 62 and the shell 10 jointly support the charging device.

[0064] It should be noted that the bracket 60 is provided with a corner portion 62, and the corner portion 62 faces the upper cover 11. In this way, when the bracket 60 drives the corner portion 62 to slide out of the housing 10, the corner portion 62 and the housing 10 jointly support the charging device. Furthermore, when the bracket 60 drives the corner portion 62 to slide into the notch, the corner portion 62 completely overlaps with the housing 10, so that the bracket 60 is completely hidden from the outside.

[0065] like Figure 1 、 Figure 3 、 Figure 6 、 Figure 12 As shown, in one embodiment, a multifunctional mobile power supply 1 is further provided with a hanging rope 70, one end of which is provided on the middle frame 12 to improve the user's carrying experience when going out.

[0066] like Figures 12 to 14 As shown, in one embodiment, a multifunctional mobile power supply 1 further includes a conversion seat 80, which includes a bottom box 81, a pressing piece 82, two iron sheets 83 and two guide pillars 84. The two guide pillars 84 are rectangular column structures, and one end of the two guide pillars 84 is passed through the bottom box 81 and extends from the inner bottom wall of the bottom box 81. The two iron sheets 83 are arranged on the pressing piece 82.

[0067] It should be noted that the pressing plate 82 is provided with two through holes, one end of the two iron sheets 83 is respectively located in the two through holes, and the other end of the two iron sheets 83 is located on the inner side wall of the pressing plate 82. When the pressing plate 82 is buckled with the bottom box 81, the two iron sheets 83 located on the inner side wall of the pressing plate 82 are respectively abutted against the two guide posts 84 extending from the inner bottom wall of the bottom box 81. Furthermore, when the two ends of the two electrode sheets 452 away from the shaft block 451 are both inserted into the two through holes, the two electrode sheets 452 are respectively abutted against the two iron sheets 83, thereby electrically connecting the two electrode sheets 452 to the two guide posts 84. Furthermore, a rectangular column is also provided on the bottom box 81, and the column and the two guide posts 84 are jointly plugged into the power supply.

[0068] like Figure 15 As shown, in one embodiment, the two guide posts 84 are flat strip structures, the angle between the two guide posts is 90 degrees, and one end of the two guide posts 84 passes through the bottom box 81 and extends from the inner bottom wall of the bottom box 81.

[0069] like Figure 16 As shown, in one embodiment, the two guide pillars 84 are cylindrical structures, a boss is provided on the bottom box 81 , one end of the two guide pillars 84 passes through the boss and the bottom box 81 , and extends from the inner bottom wall of the bottom box 81 .

[0070] It should be noted that the guide column 84 on the conversion base 80 can be a rectangular column structure, a flat strip structure, or a cylindrical structure according to the power socket type of different countries, so as to meet the user's usage needs.

[0071] The above-described embodiments merely represent several implementations of the present invention.
