The contents of the description of the original patent application are quoted in this document. Technical Field

[0002] This invention relates to the field of electrical accessories, specifically a wall-mounted wireless charging device with a movable wireless charging base. Background Technology

[0003] With the continuous development of portable electronic devices and corresponding charging devices, the technology of using wireless charging to charge portable electronic devices is becoming increasingly mature and widely used, showing great potential and market potential.

[0004] Currently available wireless charging devices use either a power outlet or USB cable as the power input, and then use a wireless charging pad to charge the device; or they use a wall-mounted wireless charging pad. However, these technologies have the following drawbacks: when using a wireless charging pad fixed to a wall or in a specific location, the device can only be placed on the pad due to the limitation of the power source, making it inconvenient to move around and use. Summary of the Invention

[0005] The purpose of this invention is to provide a wall-mounted wireless charging device with a movable wireless charging base. Users can place the wireless charging device on the charging base fixed to the wall to directly charge the wireless charging device wirelessly. Alternatively, the wireless charging base can be detached from the power socket and used as a portable power source for the wireless charging device, increasing the convenience and portability for users.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: A wall-mounted wireless charging device with a movable wireless charging base includes a wireless charging base (1) and a power supply base (2) for supplying power to the wireless charging base (1). The wireless charging base (1) includes a transmitting coil (6), a power management circuit (7), and a backup power supply (8). The transmitting coil (6) is connected to the backup power supply (8) through the power management circuit (7). The power supply base (2) is fixed to the wall and is fixed inside the wall by a concealed box (3). The wireless charging base (1) is vertically locked to the surface of the power supply base (2) by a plug-in component, a snap-fit ​​mechanism, or magnetically pluggable, forming a mechanism for supporting external devices to be charged. The power supply base (2) is provided with a power conversion circuit. The input end of the power conversion circuit is connected to the mains power, and the output end of the power conversion circuit is connected to the power management circuit (7) to convert the external power supply into the working voltage required by the wireless charging base (1). The power supply base (2) is provided with a power conversion circuit, and the power conversion circuit is connected to the input end of the power management circuit (7) through the power conversion circuit.

[0007] The wireless charging dock (1) includes a housing (4) and a top cover (5). The transmitting coil (6) and the power management circuit (7) are both located inside the housing (4). The top cover (5) covers the housing (4). The housing (4) has a through hole (9). The input terminal of the power management circuit (7) passes through the through hole (9). When the wireless charging dock (1) is plugged into the power socket (2), the power conversion circuit converts the external AC power (ACV0) and then transfers it to the power management circuit (7) through the power conversion circuit. The power management circuit (7) converts the DC voltage (DCV1) provided by the power conversion circuit back into AC voltage (ACV2) and provides it to the transmitting coil (6). At the same time, it DC charges the backup power supply (8). After receiving the AC voltage (ACV2), the transmitting coil (6) generates an alternating magnetic field. The alternating magnetic field generates a voltage (ACV4). The external device to be charged converts the voltage (ACV4) into a DC voltage (DCV5) to charge the current device.

[0008] By plugging and unplugging the wireless charging dock onto the power supply dock, which is fixed to the concealed box, the power conversion circuit inside the power supply box converts the external power into the working voltage required by the wireless charging dock. Then, it is connected to the power management circuit through the power conversion circuit to power the wireless charging dock. The charging coil in the wireless charging dock converts the voltage to charge the charging device. The backup power supply in the wireless charging dock allows it to be used as a portable power bank.

[0009] The power socket is equipped with a power conversion circuit. The power conversion circuit is connected to the input terminal of the power management circuit through the power conversion circuit, which increases the safety of use by not directly connecting the power management circuit to the power conversion circuit.

[0010] Preferably, the backup power source is a battery. Furthermore, the power adapter port electrically coupled between the power management circuit (7) and the power socket (2) uses one or more standard coupling connectors selected from USB, Lightning, Micro-USB, Type-C, and Micro-USB. This design allows both the power socket (2) and the wireless charging dock (1) to be independently connected to the external electronic device to be charged via wired connection, especially the wireless charging dock 1, which can be used as an independent power adapter.

[0011] In another effect, the vertically positioned power socket (2) is fixed inside the wall by a concealed box, reducing the usable area of ​​the device.

[0012] Compared with the prior art, the wall-mounted wireless charging device with a movable wireless charging base that adopts the above technical solution has the following beneficial effects: The wall-mounted wireless charging device with a movable wireless charging base of the present invention can detach the charging base of the wireless charging device from the main body as a mobile power source, and can be used remotely, making the entire wireless charging device more convenient to use.

[0016] like Figures 1 to 2 The wall-mounted wireless charging device with a movable wireless charging dock shown includes a wireless charging dock 1 and a power supply dock 2 that supplies power to the wireless charging dock 1. Figure 1This is a general outline view of an embodiment of the wall-mounted wireless charging device with a movable wireless charging base according to the present invention. Figure 2 This is a schematic diagram of the wall-mounted wireless charging device with a movable wireless charging dock in this embodiment. The wireless charging dock 1 includes a transmitting coil 6, a power management circuit 7, and a backup power supply 8; the power supply dock 2 contains a power conversion circuit. The input terminal of the power conversion circuit is connected to an external power source, and the output terminal of the power conversion circuit is connected to the power management circuit 7. That is, the power conversion circuit converts the external power source into the operating voltage required by the wireless charging dock 1. The external power source is generally a household AC unit or commercial AC power supply. The power supply dock 2 is equipped with a power adapter circuit, and the power conversion circuit is connected to the input terminal of the power management circuit 7 through the power adapter circuit. Figure 1 As shown, the power socket 2 is fixed in the recessed box 3, which is embedded in the wall. The wireless charging base 1 can be plugged into and detached from the power socket 2. In this embodiment, the wireless charging base 1 can be fixed to the power socket 2 through various connection methods such as connector plug-in, size transition fit or small interference fit, snap connection, magnet, Velcro or other detachable locking and fixing mechanisms.

[0017] like Figure 3 The wireless charging dock 1 shown includes a housing 4, a top cover 5, a transmitting coil 6, a power management circuit 7, and a backup power supply 8.

[0018] like Figure 4 The schematic diagram of the wall-mounted wireless charging device with a movable wireless charging base is shown. The charging principle of this embodiment is as follows: When the wireless charging dock 1 is still connected to the power dock 2, the power conversion circuit converts the external power ACV0 and then transfers it to the power management circuit 7 through the power conversion circuit. The power management circuit 7 provides the transmitting coil 6 with the voltage DCV1 provided by the power conversion circuit and the AC voltage ACV2, while charging the backup power supply 8. After receiving the voltage ACV2, the transmitting coil 6 generates an alternating magnetic field, which generates the voltage ACV4. The charging device then converts the voltage ACV4 into DCV5 to charge the device.

[0019] When the wireless charging dock 1 is detached and used as a power bank, the backup power supply 8 provides the power management circuit 7 with working power DCV3, and supplies the transmitting coil 6 with AC voltage ACV2. After receiving voltage ACV2, the transmitting coil 6 generates an alternating magnetic field, which generates voltage ACV4. The charging device then converts voltage ACV4 into DCV5 to charge the device.

[0020] The above are preferred embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the principle of the present invention, and these should also be considered within the scope of protection of the present invention.
