Description
Technical Field
[0001] This utility model relates to a power supply device with Bluetooth connectivity, belonging to the field of power supply. Background Technology
[0002] Power supply units (or power adapters), which convert AC mains power into DC power required by devices, are widely used in powering various electronic devices. Traditional power supply units have limited functionality, typically only possessing basic voltage conversion and output functions, such as charging or powering devices through one or more output ports after AC-DC conversion.
[0003] With the development of Bluetooth technology, more and more devices, such as speakers, headphones, and smart home controllers, are equipped with Bluetooth communication capabilities. These devices need to be connected to a power source and also need to pair with host devices such as mobile phones and computers via Bluetooth when they are working. In existing technology, power supply and Bluetooth communication are two separate functional modules, implemented by a power adapter and a separate Bluetooth transceiver (or a Bluetooth module built into the device), respectively. This separate solution has significant drawbacks: users need to manage both the power cord and the Bluetooth connection simultaneously, resulting in numerous cables, space consumption, and inconvenient setup, affecting ease of use and overall aesthetics.
[0004] Furthermore, most power devices that attempt to integrate more functions are limited to adding USB ports or increasing output power, without addressing the deep integration of wireless communication and power functions at the hardware level. Therefore, there is an urgent need in the field for an integrated solution that combines power supply and Bluetooth communication functions to simplify user operation, optimize device layout, and meet the growing demand for one-stop power and wireless connectivity.

[0007] An adjustable-angle fixing bracket (7) is provided at the bottom of the lower shell (102) for fixing the power supply device to a wall or table.
[0008] The DC three-way output line (4) contains three independent output ports, each of which is equipped with an overload protection circuit.
[0009] A protective shell (8) made of elastic material is fitted on one side of the outer shell (1) for shock absorption and cushioning.

[0016] 4. It adopts a DC three-way output line and is equipped with an independent overload protection circuit, which can safely and stably power multiple external devices at the same time, meeting the power needs of multiple device users and making it highly practical.
[0017] 5. The adjustable-angle mounting bracket at the bottom allows for flexible mounting on walls or desktops, adapting to various application environments such as homes, offices, and studios, and solving the problem of cluttered placement of traditional power adapters.
[0018] 6. The sealing ring design enhances dust and moisture resistance; the outer protective shell provides shock absorption; the internal thermal pad and the heat dissipation windows on the outer shell together form an effective heat dissipation system, reducing the risk of internal components being damaged by overheating, extending the service life of the device, and ensuring safety and reliability.

[0023] See Figures 1 to 3 This utility model relates to a power supply device with Bluetooth connectivity, comprising a housing 1, a power board 2 disposed inside the housing 1, an AC plug input line 3 for connecting to external mains power and a DC three-way output line 4 for supplying power to external devices connected to the power board 2; an antenna 5 is also mounted on the housing 1, the antenna 5 is electrically connected to the power board 2 via an antenna terminal 6, and a circuit board 10 electrically connected to the power board 2 is also included, the circuit board 10 integrating a Bluetooth module, and a control panel 9 electrically connected to the circuit board 10 is disposed outside the housing 1.
[0024] By simultaneously placing a power board 2 responsible for power conversion and a circuit board 10 integrating Bluetooth functionality inside the casing and electrically connecting the two, a deep hardware-level integration of power supply and Bluetooth communication functions is achieved, enabling a single device to serve two purposes and solving the problems of device separation and messy wiring in traditional solutions.
[0025] The structure adopts an antenna 5 that is reliably connected to the internal circuit board through the antenna terminal 6, and a separate circuit board 10 is set up to carry the Bluetooth module, which effectively isolates the large current interference generated by the power supply circuit and ensures the stability and anti-interference capability of Bluetooth signal transmission and reception.
[0026] The control panel 9, which is externally set up and electrically connected to the Bluetooth module circuit board, allows users to perform Bluetooth pairing, connection status viewing, and other operations directly on this device without the need for other devices. The interaction is direct and intuitive, greatly improving the convenience and user experience.
[0027] The outer shell 1 includes an upper shell 101 and a lower shell 102, which are detachably connected together. The antenna 5 is fixedly installed on the lower shell 102, which facilitates disassembly and installation.
[0028] An adjustable-angle mounting bracket 7 is provided at the bottom of the lower housing 102 for fixing the power device to a wall or desktop. It can be flexibly fixed to a wall or desktop, adapting to various application environments such as homes, offices, and studios, and solving the problem of cluttered placement of traditional power adapters.
[0029] The DC three-way output line 4 includes three independent output ports, each equipped with overload protection circuitry. It can safely and stably power multiple external devices simultaneously, meeting the power needs of multi-device users and demonstrating strong practicality.
[0030] A protective shell 8 made of elastic material is fitted on one side of the outer shell 1 for shock absorption and cushioning.
[0031] A sealing ring is provided at the connection between the upper shell 101 and the lower shell 102; a heat dissipation window is provided on the lower shell 102. A thermally conductive pad is provided between the power board 2 and the inner wall of the outer shell 1.

[0032] The Bluetooth module supports Bluetooth 4.0 and above.
[0033] The working principle of this utility model is as follows: Step 1: Power Connection and Conversion First, connect the AC plug input line 3 to the mains power. External AC power enters the power board 2 inside the device through this input line. The power board 2, as the power supply unit, performs the AC-DC conversion function, converting high-voltage AC power into low-voltage DC power to provide the required operating voltage.
[0034] Step 2: Internal module power supply and Bluetooth system startup: The DC power converted by the power board 2 powers externally connected devices through the DC tee output line 4, and also powers the Bluetooth module on the circuit board 10 electrically connected to the power board 2, enabling it to start working.

At this time, external Bluetooth devices such as mobile phones and speakers can search for and connect to the Bluetooth module, establishing a wireless communication link.
[0036] Step 4: Collaborative Work and Status Maintenance After the connection is established, this utility model performs two functions simultaneously: 1. Power supply function: The power board 2 continuously provides stable power to external devices through the DC three-way output line 4.
[0037] 2. Communication function: Data signals from external Bluetooth devices are received through antenna 5 and processed by circuit board 10; or signals generated by circuit board 10 are transmitted through antenna 5 to achieve wireless data transmission.
[0038] Throughout the operation, the heat dissipation window, thermal pad, and sealing ring work together to ensure good heat dissipation of internal components and protect them from dust and moisture; the fixed bracket 7 ensures the device is placed stably; the protective shell 8 provides physical protection; and the overload protection circuits at each port ensure electrical safety.
