[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4A PoE-enabled Type-C smart device magnetic expansion dock includes a housing with an internal cavity. A circuit board assembly 3 is installed inside the cavity. A first magnetic assembly 2 and a second magnetic assembly 5 are respectively installed on the upper and lower surfaces of the housing. The circuit board assembly 3 is electrically connected to multiple functional interfaces, including an RJ45 interface 31, an HDMI interface 32, a host interface 33, a PD Type-C interface 34, a Type-C interface 35, and a Type-A interface 36. The RJ45 interface 31, HDMI interface 32, host interface 33, PD Type-C interface 34, Type-C interface 35, and Type-A interface 36 are all located in pre-set through holes in the housing and extend outward from the through holes.

[0024] The outer casing includes an upper shell 1 and a bottom shell 4 that are connected to each other. A first positioning mounting groove 11 and a second positioning mounting groove 41 are respectively provided on the inner wall of the upper end face and the outer wall of the lower end face of the outer casing. The first magnetic suction component 2 is installed in the first positioning mounting groove 11, and the second magnetic suction component 5 is installed in the second positioning mounting groove 41. A status indicator light 37 is electrically connected to the circuit board assembly 3. The status indicator light 37 is located in a pre-set through hole in the outer casing and extends outward from the through hole. The status indicator light 37 is used to indicate the real-time working status of the docking station. A heat dissipation through hole 12 is provided on the outer casing, connecting the inside and outside of the casing. The heat dissipation through hole 12 is used for heat dissipation during the operation of the docking station, allowing the heat generated by the internal electrical components to be discharged outward, thereby preventing overheating of the docking station due to heat accumulation. An anti-slip pad 6 is provided on the outer wall of the bottom shell 4 on the side away from the upper shell 1. The anti-slip pad 6 makes the docking station more stable and less prone to sliding or shifting.

[0025] Please see Figure 5 Working principle of the example:

[0026] When the UFP USB Type C Plug is connected to a host device such as a mobile phone, tablet, or computer with Power Delivery capability, the product immediately communicates with the host uplink device so that the host uplink device can automatically recognize the product.

[0027] The USB Type-C DP Alt Mode to HDMI Converter unit consists of two built-in modules: the PowerDelivery Controller and the DisplayPort Ultra-Stream Hub Controller.

[0028] The built-in Power Delivery Controller module is responsible for communicating with host devices such as mobile phones, tablets, or computers that have Power Delivery functionality via the Power Delivery charging protocol, and also for communicating with power adapters with Power Delivery functionality plugged into the DFP1 USB Type C PD3.0 60W downstream port via the Power Delivery charging protocol. Successful communication enables PD3.0 60W fast charging service. The built-in Power Delivery Controller module establishes communication with the host upstream device connected to the UFP USB Type C Plug. It can establish communication between the power adapter with Power Delivery functionality connected to the DFP1 USB Type C PD3.0 60W downstream port and the host upstream device with Power Delivery functionality connected to the UFP USB Type C Plug upstream port of this product, providing fast charging service to the upstream host device.

[0029] After the UFP USB Type C Plug upstream device successfully recognizes this product, the product can convert the DisplayPort protocol signal to an HDMI protocol signal through the built-in DisplayPort Multi-Stream HubController module of the USB Type CDP Alt Mode to HDMI Converter unit, and establish a downstream port DFP2HDMI 4K@60Hz. This video port DFP2 HDMI 4K@60Hz can be connected to a display device with an HDMI interface, so that the small screen of the host upstream device connected to this product can be transformed into a large-screen display.

[0030] Host upstream devices connected to the UFP USB Type C Plug can communicate with this product and establish data connections and exchanges via the USB 2.0 HUB unit. Simultaneously, the USB 2.0 HUB unit generates three USB-A downstream ports: DP3 USB-A 2.0, DP4 USB-A 2.0, and DP5 USB-A 2.0. All three downstream ports can connect to downstream device devices and support bidirectional data transfer at speeds up to 480Mbps.

[0031] After the UFP USB Type C Plug upstream device successfully recognizes this product, this product communicates with the USB 3.0 Gigabit Ethernet Controller unit through the USB Type CDP Alt Mode to HDMI Converter unit to convert USB data from the Host upstream device and the USB 2.0 HUB unit into Ethernet data. After voltage conversion by the Gigabit Ethernet PoE Transformer, a downstream port DP6 RJ45 PoEGigabit is generated for connecting Ethernet devices and providing network connectivity, data exchange, and communication services.

[0032] If the downstream port DP6 RJ45 PoE Gigabit is connected to a remote network switch or router with PoE capability, the Gigabit Ethernet PoE Transformer can receive PoE power from the remote network switch or router. The received PoE AC power from the remote network switch or router is converted into high-voltage DC power by the full-wave rectifier unit, and then stepped down by the DC / DC controller to provide power to the internal power system. Simultaneously, the Power Delivery Controller unit can also establish communication with the host upstream device connected to the UFP USB Type C plug and provide fast charging service to the upstream host device.

[0033] The Power Delivery Controller unit communicates with the built-in Power Delivery Controller module of the USB Type C DP Alt Mode to HDMI Converter unit. On the one hand, it detects and identifies power adapters with Power Delivery function connected to the downstream port DFP1 USB Type C PD3.0 60W. On the other hand, it also detects and identifies the Power Delivery Controller unit, and can prioritize power adapters with Power Delivery function connected to the DFP1 USB Type C PD3.0 60W to establish communication with upstream devices with Power Delivery function connected to the upstream port UFPUSB Type C Plug of this product, and provide fast charging services to the upstream host devices.

[0034] Technology integration solution:

[0035] PoE input → PoE splitter (extracts 48V DC) → DC-DC step-down to PD3.0 compatible voltage (e.g., 20V) → PD protocol chip → Type-C hub. The voltage matching, efficiency optimization, and thermal management issues between PoE and PD3.0 need to be addressed.

[0036] In summary, this utility model incorporates an RJ45 interface, essential for PoE power supply, into the expansion dock. Furthermore, by integrating relevant PoE power supply technologies and the PD3.0 (Power Delivery) protocol, it enables power supply to the extender via Ethernet cable, simplifying cabling and providing a more flexible power supply solution for office, industrial, and smart home applications. Additionally, by providing magnetic attachment components on both sides of the expansion dock, the dock can be easily magnetically attached to other peripherals, or multiple expansion docks can be magnetically stacked, thereby enhancing the ease of use.
