[0025] like Figures 1 to 5 As shown, this utility model provides a specific embodiment of a wireless charging device.

[0026] A wireless charging device, reference Figure 1The wireless charging device includes a housing 100, a circuit board, a first wireless charging module 300, a second wireless charging module 400, and a third wireless charging module 500. The circuit board is disposed inside the housing 100. The housing 100 is provided with a first inclined surface 110 and a second inclined surface 120 adjacent to the first inclined surface 110. The first inclined surface 110 is provided with a first receiving groove 111 and a second receiving groove 112. The first wireless charging module 300 and the second wireless charging module 400 are respectively disposed in the first receiving groove 111 and the second receiving groove 112, and are both electrically connected to the circuit board. The third wireless charging module 500 is disposed on the second inclined surface 120 and can extend and retract relative to the second inclined surface 120 to be stored inside the housing 100 or exposed outside the housing 100.

[0027] Specifically, refer to Figure 1 The housing 100 is used to protect the circuit board and install the first wireless charging module 300, the second wireless charging module 400, and the third wireless charging module 500. The housing 100 can be made of ABS+PC flame-retardant material, and the bottom of the housing 100 is provided with an anti-slip silicone pad. The circuit board is used for charging control, and the circuit board is equipped with the MCU control unit, power distribution unit, protection unit, and protocol control unit required for wireless charging. The first inclined surface 110 can be set to form an angle of 135°-150° with the horizontal plane, and the second inclined surface 120 can be set to form an angle of 30°-45° with the horizontal plane. The depth of the first receiving groove 111 is adapted to the thickness of the first wireless charging module 300, and the depth of the second receiving groove 112 is adapted to the thickness of the second wireless charging module 400.

[0028] Among them, reference Figure 1 The first wireless charging module 300 is disposed in the first receiving slot 111 of the first inclined surface 110 and electrically connected to the circuit board for wireless charging of external devices such as mobile phones. The second wireless charging module 400 is disposed in the second receiving slot 112 of the second inclined surface 120 and electrically connected to the circuit board for wireless charging of external devices such as headphones. The third wireless charging module 500 is retractably disposed on the second inclined surface 120 for wireless charging of devices such as watches.

[0029] With the widespread use of smart devices, users often need to charge their phones, watches, and earphones simultaneously. Conventional wireless charging devices that only support wireless charging for a single device are no longer sufficient to meet current needs. As a result, some multi-device wireless charging devices have emerged on the market. Existing multi-device wireless charging devices generally adopt a flat layout, that is, by laying multiple wireless charging modules horizontally on the same base surface to charge different devices separately. This design not only tends to result in a large overall size of the wireless charging device, making it inconvenient to carry and use, and difficult to meet the miniaturization development, but also requires the device to be placed flat on the device when wirelessly charging, making it inconvenient to use during the charging process.

[0030] In this embodiment, a wireless charging device is designed, including a housing 100, a circuit board, a first wireless charging module 300, a second wireless charging module 400, and a third wireless charging module 500. The circuit board is disposed within the housing 100. The housing 100 has a first inclined surface 110 and a second inclined surface 120 adjacent to the first inclined surface 110. The first inclined surface 110 has a first receiving groove 111 and a second receiving groove 112. The first wireless charging module 300 and the second wireless charging module 400 are respectively disposed within the first receiving groove 111 and the second receiving groove 112, and are both electrically connected to the circuit board. The third wireless charging module 500 is disposed on the second inclined surface 120 and is oriented relative to the circuit board. The second inclined surface 120 is retractable to be stored inside the housing 100 or exposed outside the housing 100. By setting the first wireless charging module 300 and the second charging module on the first inclined surface 110, it is used to wirelessly charge operable electronic devices (such as mobile phones, tablets, etc.). When the electronic device needs to be wirelessly charged, it only needs to be tilted upward and attached to the first wireless charging module 300, which makes it more convenient for users to use during the wireless charging process. Furthermore, by retracting the third wireless charging module 500 on the second inclined surface 120, the layout is more compact, effectively reducing the overall volume of the wireless charging device. When the third wireless charging module 500 is not in use, it can be stored inside the housing 100, making it more convenient to carry.

[0031] In one embodiment, reference Figure 2The wireless charging device also includes a rotating module 600. One end of the rotating module 600 is rotatably connected to the housing 100, and the other end is rotatably connected to the first wireless charging module 300. On the one hand, the first wireless charging module 300 can be adjusted in height and angle relative to the housing 100 via the rotating module 600. When the device is placed on the first wireless charging module 300 for wireless charging, the height and angle of the first wireless charging module 300 can be adjusted according to the user's usage habits, thereby adjusting the position of the device and making it more convenient for the user to view or operate the device during wireless charging. On the other hand, when the first wireless charging module 300 is not in use, it can be stored in the first receiving slot 111 via the rotating module 600, thereby reducing the overall size of the wireless charging device and making it more convenient to carry and store.
