Furthermore, wireless charging standards are gradually becoming more unified; for example, the Qi standard is gaining increasing popularity in the market, which helps improve user experience and device compatibility.

[0003] Wireless charging technology is currently widely used in smartphones, wearable devices, automotive electronics, and home appliances. However, due to differences in the size of mobile devices and their wireless sensing range, wireless chargers are not universally compatible. Users who have purchased mobile devices such as phones, headphones, and watches need to buy multiple chargers to charge them, which is inconvenient in terms of carrying and use. Utility Model Content

[0004] The present invention aims to overcome at least one of the defects of the prior art and provide a foldable multi-functional wireless charger to achieve the purpose of being easy to carry and enabling wireless charging of various mobile devices.

[0005] Specifically, the present invention provides a foldable multi-functional wireless charger, comprising a first charging component, a second charging component, and a third charging component connected in sequence; the first charging component and the second charging component are folded and rotated together; the second charging component and the third charging component are horizontally rotated together; the first charging component, the second charging component, and the third charging component are used for charging mobile devices, the mobile devices including at least one of mobile phones, headphones, and watches.

[0006] Preferably, in this utility model, the first charging component is mainly used for wireless charging of mobile phones. The first charging component rotates relative to the second charging component by folding it in half, so that the two can form an angle relative to each other to form a mobile phone stand. The mobile phone can be attached to the first charging component for charging, and at the same time, it can also be used as a stand.

[0007] The second and third charging components can be used to charge headphones and / or watches. In use, the second and third charging components can be in a horizontal position; placing the watch or headphones on top enables wireless charging. Therefore, this invention uses multiple charging modules to form a multi-functional wireless charger, and each charging module is connected by a rotating mechanism, facilitating storage and folding, and unfolding is equally convenient and quick.

[0008] Furthermore, the first charging component includes a first bracket, a first charging module, a first circuit board, and a first connecting mechanism; the first bracket is connected to the second charging component through the first connecting mechanism; the first charging module is connected to the first circuit board and fixed on the first bracket.

[0009] The first charging component of this utility model can be used for charging mobile communication devices such as mobile phones or tablets. The first bracket serves to support the charging device and install internal electrical components. The first bracket includes a first upper cover, a first middle cover, and a first lower cover. The first upper cover and the first lower cover can be interlocked, and the first middle cover is fitted into the side between the two to form a mobile phone bracket housing. A first connecting mechanism is located at the end of the housing, serving to connect the housing and the second charging component. The first circuit board is located between the first upper cover and the first lower cover, and is located below the first charging module. A mounting opening is provided in the middle of the first upper cover, and the first charging module is mounted and fixed in the mounting opening. The surface of the first charging module is also provided with a silicone pad to facilitate the phone's fit and fixation during charging, prevent slippage, and protect the phone's back panel, reducing impact damage.

[0010] Furthermore, the first connecting mechanism includes a first connecting seat, a first rotating shaft, and a rotating shaft fixing seat; the rotating shaft fixing seat is fixed to one end of the first bracket; the bottom of the first connecting seat is fixed to the second charging component, and the upper two ends are provided with insertion holes; one end of the first rotating shaft is inserted into the rotating shaft fixing seat, and the other end is inserted into the insertion hole; the first rotating shaft is also provided with a limiting locking block, so that when the first bracket rotates relative to the second charging component, it achieves limiting locking. The first connecting seat has a similar inverted T-shaped structure, with the bottom fixed to the second charging component, and the upper part rotatably connected to the first lower cover through the first rotating shaft. The rotating shaft fixing seat is connected to the first lower cover through screws and is located in the phone holder housing. Preferably, there are two first rotating shafts and two rotating shaft fixing seats; one end of each first rotating shaft is inserted into a rotating shaft fixing seat and fixed, and the other end is inserted into the insertion hole of the first connecting seat and can rotate, thus achieving a rotatable connection.

[0011] In order to fix and adjust the angle of the first bracket relative to the second charging component, this utility model also designs a limiting locking block, preferably limiting the rotation angle of the first bracket to 0 to 75°.

[0012] Furthermore, the limiting locking block is annular and disposed on the first rotating shaft. The first rotating shaft has anti-slip texture and a flat cut on one side. The limiting locking block has a flat latch on one side that is on the same plane as the flat cut. When the first bracket rotates, the first rotating shaft rotates to the position of the flat cut, so that the first rotating shaft is locked relative to the first connecting seat. At this time, the flat latch is limited by the rotating shaft fixing seat and cannot continue to rotate, so that the rotation range of the first bracket relative to the second charging component is 0 to 75°.

[0013] Furthermore, the second charging component includes a second bracket, a second circuit board, a coil module, and a second connecting mechanism; one end of the second bracket is rotatably connected to the first bracket through the first connecting mechanism, and the other end of the second bracket is rotatably connected to the third charging component through the second connecting mechanism; the second circuit board and the coil module are fixedly installed in the second bracket.

[0014] Preferably, the second charging component of this invention is mainly used for charging Bluetooth earphones. Wireless charging is achieved by placing the earphone case on the second charging component. The second bracket includes a second upper cover and a second lower cover; the second circuit board is located at one end of the accommodating space formed by the upper and lower covers, and the coil module is located in the middle of the accommodating space. After placing the Bluetooth earphone on the second upper cover, charging of the earphone case is achieved through the coil module. More preferably, a light guide post and a power connector are also provided on one side of the second lower cover.

[0015] Furthermore, the second connecting mechanism is a disc-shaped rotating shaft structure, including a second connecting seat, a second rotating shaft, and a third connecting seat; the second connecting seat is fixed to the second bracket; the third connecting seat is fixed to the third charging component; one end of the second rotating shaft is inserted into the second connecting seat, and the other end is inserted into the third connecting seat; so that the third charging component can rotate relative to the second bracket.

[0016] The second connecting mechanism of this utility model mainly realizes the rotatable connection between the second lower cover and the third charging component. The second connecting seat and the third connecting seat are used to fix the second lower cover and the third charging component, respectively. The lower part of the second rotating shaft is fixed to the third connecting seat, and the upper part is rotatably connected to the second connecting seat. Another implementation is that the lower part of the second rotating shaft is rotatably connected to the third connecting seat, and the upper part is fixedly connected to the second connecting seat.

[0017] Furthermore, the second connecting mechanism also includes a limiting mechanism and a damping plate. The limiting mechanism is located on the side of the second connecting seat, and the damping plate is located on the side of the second rotating shaft. The limiting mechanism and the damping plate limit the rotation angle of the third charging component to 0 to 180°.

[0018] To ensure relative stability between the second lower cover and the third charging component after the third charging component rotates 180°, this invention incorporates a limiting mechanism. This limiting mechanism is mounted on the second connecting seat and is preferably a one-piece structure. The second connecting seat is disc-shaped with three side wings, each fixed to the second lower cover by screws. Preferably, a limiting mechanism protruding in a "7" shape is provided between at least two side wings. The damping plate is located on the side of the second rotating shaft and rotates via the second rotating shaft, causing the damping plate to be stopped when it reaches the position of the limiting mechanism, thus achieving the limiting effect.

[0019] Preferably, the second charging component further includes a counterweight, which is disposed in the second bracket. The counterweight is semi-circular and disposed in the accommodating space.

[0020] Furthermore, the third charging component includes a third bracket, a third charging module, and a third connecting mechanism; the third bracket is rotatably connected to the second charging component; the third charging module is rotatably connected in the longitudinal direction through the third connecting mechanism.

[0021] The third charging component is mainly used for charging the watch. Since the charging position of the watch is on the dial, the dial can be disassembled and placed directly on the third bracket. Alternatively, the third charging module can be rotated to a vertical position, and the entire watch can be placed on the third bracket so that the back of the dial is in contact with the third charging module for charging. Similarly, the third bracket includes a third upper cover and a third lower cover, which are interlocked. The third charging module is located above the third upper cover, and the third upper cover has a cavity in the middle that matches the third charging module, allowing the third charging module to be housed within it. Further, the third connecting mechanism includes a fourth connecting seat, a third rotating shaft, a fifth connecting seat, and a sixth connecting seat. The fourth and sixth connecting seats are respectively fixed to the third bracket. One end of the third rotating shaft is rotatably connected to the fourth connecting seat, the middle part passes through the fifth connecting seat, and the other end is rotatably connected to the sixth connecting seat. The third charging module is located on the fifth connecting seat. The third connecting mechanism is fixed to the third lower cover, and the installation of the third upper cover does not affect the rotation of the third connecting mechanism.
