[0059] This application discloses a foldable mobile power supply, which includes some or all of the technical features of the following embodiments; that is, the foldable mobile power supply includes some or all of the following structures. In one embodiment of this application, a foldable mobile power supply includes a mobile power supply main body, a wireless charging component and a rotating shaft component; the rotating shaft component includes a rotating shaft seat and two rotating shaft structures rotatably connected to the rotating shaft seat; the two rotating shaft structures are respectively arranged on the wireless charging component, and the rotating shaft seat is arranged on the mobile power supply main body; the mobile power supply main body is provided with an FPC cable, the wireless charging component is provided with a wireless charging function board, the rotating shaft seat is provided with an FPC cable through hole, and the FPC cable passes through the FPC cable through hole and is connected to the wireless charging function board. For the above-mentioned foldable mobile power supply, through the cooperation of the two rotating shaft structures with the rotating shaft seat, the wireless charging component and the mobile power supply main body, on the one hand, the rotation of the wireless charging component relative to the mobile power supply main body is more firm and reliable. On the premise of realizing the folding function, the strength of the folding part is improved, and it is very stable when opening and folding during use, thus extending the folding service life of the foldable mobile power supply; on the other hand, the wireless charging component is separated from the mobile power supply main body, which is beneficial to reducing the product size; on the other hand, because the wireless charging component is separated from the mobile power supply main body, it is beneficial to the heat dissipation of the wireless charging coil, making the charging performance more stable, and thus beneficial to further reducing the product size. The following combines Figures 1 to 9 , and will elaborate on the foldable mobile power supply in detail.

[0060] In one of the embodiments, a foldable mobile power supply 100 is as Figure 1 and Figure 2As shown, it includes a mobile power supply main body 200, a wireless charging component 300, and a rotating shaft component 400; the mobile power supply main body 200 and the wireless charging component 300 are rotatably connected through the rotating shaft component 400, and rotation can be achieved between the mobile power supply main body 200 and the wireless charging component 300 through the rotating shaft component 400. With such a structural design, the folding mobile power supply 100 has the wireless charging component 300 and the mobile power supply main body 200 placed separately, and the two are rotatably connected through the rotating shaft component 400, thus providing a basic folding function.

[0061] In one embodiment, as Figure 3 and Figure 4 shown, the mobile power supply main body 200 is used to connect an external wire 500 to access an external power supply through the external wire 500. In this embodiment, the folding mobile power supply 100 further includes the external wire 500. As an example, in combination with Figure 1 and Figure 2 , two receiving ports 292 are provided on the mobile power supply main body 200 or its bottom case 280, and the two connection ends of the external wire 500 are respectively detachably disposed in the two receiving ports 292. With such a structural design, it is beneficial to protect the two connection ends of the external wire 500 while storing the external wire 500.

[0062] In each embodiment, as Figure 5 and Figure 6 shown, the rotating shaft component 400 includes a rotating shaft seat 430 and two rotating shaft structures rotatably connected to the rotating shaft seat 430; the two rotating shaft structures are respectively disposed on the wireless charging component 300, and the rotating shaft seat 430 is disposed on the mobile power supply main body 200. In this embodiment, the two rotating shaft structures are respectively a first rotating shaft 410 and a second rotating shaft 420. The design of the two rotating shaft structures makes the relative rotation between the mobile power supply main body 200 and the wireless charging component 300 more force-balanced compared to a single rotating shaft, making the rotation of the wireless charging component 300 more firm and reliable. In combination with Figure 7 and Figure 8 , the mobile power supply main body 200 is provided with an FPC cable 220, the wireless charging component 300 is provided with a wireless charging function board 350, the rotating shaft seat 430 is provided with an FPC cable through hole 432, and the FPC cable 220 passes through the FPC cable through hole 432 to be connected to the wireless charging function board 350. With such a structural design, in a state where the wireless charging component 300 is separated from the mobile power supply main body 200, the mobile power supply main body 200 can be electrically connected to the wireless charging component 300 through the FPC cable 220, thereby realizing electrical signal transmission and power transmission.

[0063] In each embodiment, asFigure 5 and Figure 6 As shown, the wireless charging component 300 includes an upper shell 370, a charging coil 340 and a wireless charging function board 350. The charging coil 340, the wireless charging function board 350 and the two rotating shaft structures are respectively arranged on the upper shell 370, and the charging coil 340 is connected to the wireless charging function board 350; Figure 8 The mobile power supply body 200 includes a lower shell 210, an FPC cable 220, and a battery cell 230. The battery cell 230 and the hinge seat 430 are disposed in the lower shell 210. The battery cell 230 is used to connect to the external wiring material 500. The FPC cable 220 is connected to the battery cell 230, and the FPC cable 220 passes through the FPC cable via 432 of the hinge seat 430 to connect to the wireless charging function board 350. For example, the lower shell 210 itself forms an enclosed area, such as a power cavity 290, and the battery cell 230 and the hinge seat 430 are disposed in the enclosed area formed by the lower shell 210; alternatively, the lower shell 210 cooperates with other structural components, such as the bottom shell 280 described below, to form an enclosed area, and the battery cell 230 and the hinge seat 430 are disposed in the enclosed area formed by the lower shell 210. The remaining embodiments are similar and will not be described in detail.

[0064] For example, the battery cell 230 is used to connect to the external wiring material 500, including the battery cell 230 connecting to the external wiring material 500 via its own conversion circuit, and the battery cell 230 connecting to the external wiring material 500 via an intermediate component, such as the motherboard 250 described below, that is, the connection can be direct or indirect. Similarly, the FPC cable 220 is connected to the battery cell 230, including the FPC cable 220 connecting to the output circuit of the battery cell 230, and the FPC cable 220 connecting to the battery cell 230 via an intermediate component, such as the motherboard 250 described below. The embodiments of this application do not impose additional limitations on this.

[0065] In one embodiment, the upper shell 370 is a metal preform, and / or the lower shell 210 is a metal preform. For example, the upper shell 370 and the lower shell 210 are aluminum alloy preforms, i.e., the upper shell 370 and the lower shell 210 fixed to the hinge assembly 400 are made of aluminum alloy. In contrast, conventional foldable wireless power banks use plastic shells, which have insufficient strength and heat dissipation. The present application utilizes an upper shell 370 and a lower shell 210 in conjunction with a hinge assembly 400, which improves the reliability of folding and rotation, enhances the conductive heat dissipation performance of the charging coil 340 and the wireless charging function board 350, and facilitates heat dissipation of the wireless charging coil 340, resulting in more stable charging performance. Furthermore, the charging coil 340 is separated from the battery cell 230, which helps reduce the product size.

[0066] In one embodiment, Figure 5 and Figure 6 As shown, the wireless charging assembly 300 further includes a housing 310 and an adsorption magnet 320. The housing 310 is connected to the upper housing 370 and together they form a receiving cavity 390. The adsorption magnet 320 is disposed outside the charging coil 340, and the adsorption magnet 320, the charging coil 340, and the wireless charging function board 350 are respectively disposed within the receiving cavity 390. In this embodiment, the wireless charging assembly 300 further includes an orientation magnet 330, and an orientation position 391 is provided on the housing 310 or the upper housing 370. The orientation magnet 330 is disposed within the receiving cavity 390, at least partially within the orientation position 391. This structural design facilitates accurate installation of the two magnets, namely the adsorption magnet 320 and the orientation magnet 330.

[0067] In one embodiment, the wireless charging function board 350 is mounted on the upper shell 370 via a fourth fixing member 380. In one embodiment, the wireless charging assembly 300 includes heat dissipation silicone between the upper shell 370 and the wireless charging function board 350. In one embodiment, the wireless charging function board 350 is mounted on the upper shell 370 via a fourth fixing member 380, and heat dissipation silicone is installed between the upper shell 370 and the wireless charging function board 350. The remaining embodiments are similar and are not described in detail here. This structural design not only helps to fix the relative position of the wireless charging function board 350 and the upper shell 370 via the fourth fixing member 380, but also enhances the structural stability of the wireless charging assembly 300. It also helps to improve the heat dissipation of the wireless charging coil 340 through the heat dissipation silicone in conjunction with the upper shell 370, ensuring a stable working environment for the wireless charging coil 340 and thus ensuring stable charging performance.

[0068] In one embodiment, the rotating shaft structure includes a bracket, a shaft sleeve and a mating shaft; the bracket is disposed on the upper shell 370 and connected to the shaft sleeve; one end of the mating shaft is rotatably disposed on the shaft sleeve, and the other end is disposed on the rotating shaft seat 430, so that the bracket and the rotating shaft seat 430 are rotatably connected. In combination with Figure 7 and Figure 8 , the two rotating shaft structures are respectively a first rotating shaft 410 and a second rotating shaft 420. The first rotating shaft 410 includes a first mating shaft 413 and integrally provided first bracket 411 and first shaft sleeve 412. The first rotating end 414 of the first mating shaft 413 is rotatably disposed on the first shaft sleeve 412, and the first fixed end 415 is disposed on the rotating shaft seat 430; the second rotating shaft 420 includes a second mating shaft 423 and integrally provided second bracket 421 and second shaft sleeve 422. The second rotating end 424 of the second mating shaft 423 is rotatably disposed on the second shaft sleeve 422, and the second fixed end 425 is disposed on the rotating shaft seat 430. With such a structural design, through the cooperation of the two rotating shaft structures and the rotating shaft seat 430, a stable, reliable and durable rotating function is achieved, making the rotation of the wireless charging component 300 more firm and reliable. On the premise of realizing the folding function, the strength of the folding part is improved, and it is very stable when opening and folding during use, thereby extending the folding service life of the folding mobile power supply 100.

[0069] Exemplarily, in one embodiment, the first mating shaft 413 and the second mating shaft 423 are respectively disposed on the rotating shaft seat 430 through second fixing members 202. The first bracket 411 and the second bracket 421 are respectively disposed on the upper shell 370 through third fixing members 360. Each fixing member, including the first fixing member 201, the second fixing member 202, the third fixing member 360 and the fourth fixing member 380, may be a screwed member such as a screw or a bolt, or may be a clamping member such as a hook or a buckle. The embodiments of the present application do not make additional restrictions on this, as long as the corresponding fixing function can be achieved.

[0070] In one embodiment, the mating shaft is inserted into the mating shaft mounting hole 431 of the rotating shaft seat 430 and is disposed on the rotating shaft seat 430 through a second fixing member 202. For the embodiment having the first mating shaft 413 and the second mating shaft 423, in combination with Figure 7 and Figure 8The first mating shaft 413 and the second mating shaft 423 are respectively inserted into the two mating shaft mounting holes 431 of the rotating shaft seat 430, that is, the first mating shaft 413 is inserted into one mating shaft mounting hole 431 of the rotating shaft seat 430, and the second mating shaft 423 is inserted into the other mating shaft mounting hole 431 of the rotating shaft seat 430. In one embodiment, the mating shafts are damped in engagement with the bushings, that is, the two mating shafts are damped in engagement with the two bushings respectively, that is, the first rotating end 414 of the first mating shaft 413 is rotatably disposed on the first bushing 412 and is damped in engagement with the first bushing 412, and the second rotating end 424 of the second mating shaft 423 is rotatably disposed on the second bushing 422 and is damped in engagement with the second bushing 422. Such a structural design, on the one hand, ensures the effectiveness and reliability of the rotational connection between the wireless charging assembly 300 and the mobile power supply body 200 by inserting and fixing the two mating shafts into the two mating shaft mounting holes 431 respectively. On the other hand, the damping cooperation helps to reduce vibration stress, instantaneous impact force and arbitrarily and stably ensure the angle between the wireless charging assembly and the mobile power supply body, thereby protecting the shaft assembly 400 and the mobile power supply body 200 and the wireless charging assembly 300 connected to the shaft assembly 400.

[0071] In one embodiment, Figure 6 and Figure 7 As shown, the upper shell 370 has a long side, and the length of each bracket is 50% to 80% of the length of the long side. For the embodiment with the first bracket 411 and the second bracket 421, the length of the first bracket 411 and the second bracket 421 are 50% to 80% of the length of the long side. Exemplarily, the length of each of the first bracket 411 and the second bracket 421 is 80% of the length of the long side; alternatively, the first bracket 411 is 50% of the length of the long side, and the length of the second bracket 421 is 70% of the length of the long side; alternatively, the first bracket 411 is 75% of the length of the long side, and the length of the second bracket 421 is 63% of the length of the long side. The same applies to the remaining embodiments and is not further described. This structural design, by adopting a double-axle and extended bracket design, further improves the structural stability of the hinge assembly 400, especially the two hinge structures, and ensures the design life of the hinge assembly 400. The first bracket 411 and the second bracket 421 can be optionally made of metal parts, which is further conducive to ensuring the strength of the folding part while realizing the folding function.

[0072] In one embodiment, Figure 7As shown, a bent portion 426 is provided at the edge of the bracket. Exemplarily, the upper shell 370 has a long side, and the bent portion 426 is provided at the edge of the bracket corresponding to the long side. Exemplarily, in one embodiment, the bent portion 426 is turned over to form an arc-shaped edge. For the embodiment having the first bracket 411 and the second bracket 421, that is, the edges of the first bracket 411 and the second bracket 421 are respectively provided with the bent portion 426. Such a structural design makes the fixation of the first bracket 411 and the second bracket 421 to the upper shell 370 more stable, so that the fixation of the first rotating shaft 410 and the second rotating shaft 420 to the upper shell 370 is more stable, and thus the mobile power supply main body 200 and the wireless charging assembly 300 are more firm when folding and rotating.

[0073] In one embodiment, as Figure 8 and Figure 9 shown, the mobile power supply main body 200 further includes a main board 250 and a bottom shell 280; the bottom shell 280 is connected to the lower shell 210 and together encloses a power supply cavity 290, the battery cell 230 is connected to the main board 250, and the battery cell 230 and the main board 250 are respectively disposed in the power supply cavity 290; the FPC cable 220 is connected to the battery cell 230 through the main board 250; a wiring port 291 is opened on the bottom shell 280, and the female socket interface 251 of the main board 250 is used to connect to the external wiring 500 through the wiring port 291; Exemplarily, the external wiring 500 is connected to the female socket interface 251 provided on the main board 250 through the wiring port 291; that is, the female socket interface 251 of the main board 250 is electrically connected to the wiring port 291, and the wiring port 291 is electrically connected to the external wiring 500. Exemplarily, the external wiring 500 has two connection ends, and the specifications of the two connection ends can be the same or different. For the connection ends with the same specification, only one wiring port 291 can be provided. For the connection ends with different specifications, two different wiring ports 291 can be correspondingly provided. In the use state, one connection end is inserted into the wiring port 291 to connect to the main board 250 through the female socket interface 251 or directly connect to the main board 250; the other connection end is connected to an external power supply such as a charger. In the storage state, the two connection ends can be respectively inserted into the two storage ports 292.

[0074] In contrast, the wireless charging coils of traditional foldable wireless power banks are mostly directly connected to the motherboard, and the wire diameter of the wireless charging coils is relatively large. The components for wireless charging are also mostly placed on the motherboard controlled by the battery cells, which will result in the size of the entire product being relatively large. In contrast, the mobile power main body 200 of the present application is separately arranged from the wireless charging component 300. Specifically, the charging coil 340 and the wireless charging function board 350 are separated from the battery cells 230 and the motherboard 250. The wireless charging component 300 and the motherboard 250 are placed separately and electrically connected through the FPC cable 220. Therefore, the volume of the mobile power main body 200, especially the motherboard 250, is reduced, which is conducive to reducing the product size.

[0075] For example, in one embodiment, the mainboard 250 is mounted on the bottom housing 280 via a first fixing member 201. In one embodiment, the bottom housing 280 defines a button port 293. The mobile power supply body 200 further includes a button 270, which is mounted on the bottom housing 280 and connected to the mainboard 250 through the button port 293. In one embodiment, the mobile power supply body 200 further includes a light shield 240 and a light guide 260 disposed within the power cavity 290. The mainboard 250 sequentially emits light through the light guide 260 and the light shield 240, thereby being visible outside the bottom housing 280. This structural design facilitates the use of the button 270 to perform predetermined functions, including but not limited to turning the foldable mobile power supply 100 on and off. It also facilitates adjusting the light output of the indicator light on the mainboard 250 through the light shield 240 and the light guide 260, providing appropriate charging indications.

[0076] In one embodiment, the combination Figure 8 and Figure 9 The mobile power supply body 200 also includes a buffer 203 and a flame retardant 204. The battery cell 230 is flat in shape, with the buffers 203 disposed on both surfaces of the battery cell 230, and the flame retardant 204 disposed around the sides of the battery cell 230. For example, in one embodiment, the buffer 203 is foam, providing a flexible cushioning effect to protect the battery cell 230. For example, in one embodiment, the flame retardant 204 is barley paper, providing high-temperature resistance, fire resistance, and flame retardancy. This structural design not only helps protect the battery cell 230 through the buffer 203, preventing it from being damaged by accidental collisions, but also helps reduce the rate of spontaneous combustion output through the flame retardant 204 in the event of spontaneous combustion of the battery cell 230, thereby improving the safety of the foldable mobile power supply 100.

[0077] Next, continue to combine Figures 1 to 9, an example is used to illustrate the foldable mobile power supply 100. In one embodiment, the foldable mobile power supply 100 includes a mobile power supply main body 200 and a wireless charging component 300; in a preferred solution, it further includes an external wire 500, that is, the built-in wire assembly of the foldable mobile power supply 100; the mobile power supply main body 200 and the wireless charging component 300 are rotatably connected together through a rotating shaft component 400; the mobile power supply main body 200 includes a lower case 210, an FPC flexible cable 220, a battery cell 230, a light shield 240, a main board 250, a light guide column 260, a button 270, and a bottom case 280; the lower case 210 and the bottom case 280 are assembled together by snap fit or ultrasonic means. The ultrasonic assembly method is also called ultrasonic welding, which is to embed metal components into thermoplastic material components through ultrasonic waves; the main board 250 is fixed on the bottom case 280 by a first fixing member 201.

[0078] The wireless charging component 300 includes a face shell 310, an adsorption magnet 320, an orientation magnet 330, a charging coil 340, a wireless charging function board 350, a third fixing member 360, an upper case 370, a fourth fixing member 380, etc. The upper case 370 and the face shell 310 are assembled together by snap fit or ultrasonic means. The two magnets, the adsorption magnet 320 and the orientation magnet 330, are fixed on the face shell 310 by bonding. The charging coil 340 is fixed on the upper case 370, which is beneficial to the heat dissipation of the wireless charging coil 340 and makes the charging performance more stable; the wireless charging function board 350 is fixed on the upper case 370 by a fourth fixing member 380, and the space between them is filled with heat dissipation silica gel to make the heat dissipation effect of the wireless charging component 300 better.

[0079] The rotating shaft assembly 400 includes a first rotating shaft 410 and a second rotating shaft 420. Taking the left - right direction as an example in the illustration, the first rotating shaft 410 is the left rotating shaft, and the second rotating shaft 420 is the right rotating shaft. By the same token, the left rotating shaft includes a left bracket and a left bushing connected to the left bracket, and the right rotating shaft includes a right bracket and a right bushing connected to the right bracket. One end of the lower shell 210 is provided with a rotating shaft seat 430, and a mating shaft mounting hole 431 is provided on the rotating shaft seat 430. The left bracket and the right bracket are respectively fixed on the lower shell 210 through a third fixing member 360. There are two mating shafts corresponding to each other. The axis of the first mating shaft 413 is in damping fit with the left bushing, and the axis of the second mating shaft 423 is in damping fit with the right bushing. The fixed ends of the two mating shafts are respectively inserted into the left - right mating shaft mounting holes 431 on the rotating shaft seat 430, and the fixed ends of the mating shafts are fixed on the rotating shaft seat 430 through a second fixing member 202, thereby realizing the rotational connection between the wireless charging assembly 300 and the mobile power main body 200. A FPC cable through - hole 432 is provided on the rotating shaft seat 430. One end of the FPC cable 220 is electrically connected to the main board 250, and the other end passes through the FPC cable through - hole 432 and is electrically connected to the wireless charging function board 350. With such a structural design, the wireless charging assembly 300 rotates more firmly and reliably, and the heat dissipation effect of the product is better.

[0080] The left - right rotating shafts are fixed on the upper shell 370 by fixing their respective left - right brackets with a third fixing member 360. Moreover, the left - right brackets are designed with the bracket length deliberately lengthened and the side edges flanged, making the fixation of the left - right rotating shafts to the upper shell 370 more stable and more firm during folding and rotation. The mating shafts are fixed on the lower shell 210 through a second fixing member 202, and the mating shaft mounting holes 431 on the rotating shaft seat 430 of the lower shell 210 are deliberately made into profiling holes so that the cross - sectional shape of the mating shaft mounting holes 431 is consistent with the cross - sectional shape of the fixed ends of the mating shafts, making the rotation and folding of the rotating shafts more stable. With such a structural design, the strength of the folding part is high, it is very stable when opening and folding during folding use, and the service life is long.

[0081] One end of the FPC cable 220 is connected to the main board 250 through a connector, and one end passes through the FPC cable through - hole 432 reserved on the lower shell 210 and is electrically connected to the wireless charging function board 350 of the wireless charging assembly 300, achieving the effect of supplying power to the wireless charging function board 350. Inside the lower part of the lower shell 210 are the main board 250 and the battery cell 230, so that the heat dissipation effect of the folding mobile power supply 100 as a whole can be improved through the lower shell 210. With such a structural design, the area of the main board 250 is smaller, and the overall product size is smaller.

[0082] The external wire 500 comes with two connection ends, namely interface plugs, which are Lightning plug and Type-C plug respectively, corresponding to the female socket interfaces on the main board 250, for example corresponding to the wiring port 291 on the bottom shell 280, so as to connect the female socket interfaces on the main board 250 through the wiring port 291; the two plugs can be one or two of USB-A plug, Lightning plug, Type-C plug, and micro usb plug, and correspond to the female socket interfaces on the main board 250.

[0083] It should be noted that other embodiments of the present application further include a foldable mobile power supply formed by the combination of the technical features in the above embodiments and capable of being implemented.

[0084] The technical features of the above-described embodiments can be combined arbitrarily.
