However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of this utility model.

[0023] See Figures 1-6 This application provides a portable router module box, including a router shell 1 composed of a router top cover 11 and a router bottom cover 12. The router top cover 11 and the router bottom cover 12 are assembled and connected by screws. An integrated circuit board 2 and a router module 3 are provided inside the router shell 1. The integrated circuit board 2 and the router module 3 are electrically connected.

[0024] See Figure 1 Specifically, the router top cover 11, router bottom cover 12, integrated circuit board 2 and router module 3 are all provided with multiple connection holes 4. Multiple height-increasing posts 5 are provided between the integrated circuit board 2 and the router module 3. The height-increasing posts 5 are correspondingly arranged with the connection holes 4. The router top cover 11, router bottom cover 12, integrated circuit board 2, router module 3 and height-increasing posts 5 are connected by screws through the connection holes 4.

[0025] See Figure 2 Specifically, the router cover 11 includes an upper cover plate 111 and a lower connecting plate 112. The upper cover plate 111 is connected to the lower connecting plate 112. The upper cover plate 111 has an antenna insertion hole 113 for installing an antenna. The lower connecting plate 112 has an interface slot 114 and a network port slot 115 on one side.

[0026] See Figure 3 Specifically, the router's lower cover 12 has ventilation holes 121 that penetrate the side wall of the router's lower cover 12, and the side wall of the router's lower cover 12 has a through interface 122.

[0027] See Figure 4Specifically, the integrated circuit board 2 integrates a network port 21, a USB interface 22, a network port to USB chip 23, and a power voltage conversion chip 24. The network port 21, the USB interface 22, and the power voltage conversion chip 24 are respectively connected to different pins of the network port to USB chip 23.

[0028] See Figure 5 Specifically, the router module 3 integrates an ingress port 31, an egress port 32, a router power supply port 33, and a status indicator light 34. The ingress port 31, egress port 32, router power supply port 33, and status indicator light 34 are respectively distributed on different edges of the router module 3. The status indicator light 34 is close to the ventilation hole 121, thereby facilitating the illumination status of the status indicator light 34. The egress port 32 is connected to the integrated circuit board 2 through a wire.

[0029] Specifically, the router module 3 has a heat sink at the bottom, a thermal grease layer between the heat sink and the bottom of the router module 3, and a thermal silicone layer around the thermal grease layer.

[0030] Further explanation:

[0031] To address the issues of USB to Ethernet protocol conversion, router power supply, and inconsistencies between the router module's network port interface and the actual interface used, a circuit board was designed that integrates USB to Ethernet conversion, network port wiring conversion, and power supply voltage conversion.

[0032] The Ethernet-to-USB chip in the circuit board can be selected as the SR9900A. The SR9900A is a highly integrated, low-power, single-chip USB 2.0 to 10 / 100M Ethernet control circuit. It adds low-cost, small-package, plug-and-play Fast Ethernet functionality to various applications, including desktop computers, laptops, ultra-portable computers, tablets, docking stations / port replicators / extension stations, game consoles, smart home devices, and any embedded device with a USB interface, while also being economical and practical.

[0033] The power supply voltage conversion chip can be selected as SX1308, which is a constant frequency, 6-pin SOT23 packaged DC-DC boost converter.

[0034] The core of DC-DC synchronous rectification technology is to replace traditional rectifier diodes with low on-resistance MOSFETs (called synchronous rectifier diodes). By precisely controlling the switching state of the MOSFETs, energy loss is reduced. The DC-DC control logic works by detecting the inductor current direction or the switching node voltage. The controller triggers the synchronous rectifier diode to turn on and off at the appropriate time, ensuring its operation is synchronized with the main switch. This allows for duty cycle adjustment to achieve the ideal voltage. This chip is small and suitable for small, low-power applications. Therefore, we chose the SX1308 as our boost chip. The SX1308 has a switching frequency of 1.2MHz, allowing the use of miniature, low-cost capacitors and inductors with a height of 2mm or less. The 5V power input from the USB port is boosted to 12V by this chip to power the router.

[0035] Meanwhile, the PCB board is highly compatible with the router module in terms of opening position and size, and also has the function of changing the network port wiring sequence. In terms of interface, it uses MX1.25, which is the same as the router module selected below, and can be perfectly adapted to the router module.

[0036] Regarding the issue of router overheating, the main heat source of the router is the main control chip. In actual tests, the temperature can reach nearly 80°C after 5 minutes of use at a room temperature of 25°C. To address this, you can use Deepcool DM9 thermal paste and a copper heatsink, and then use Kraft 5205 high thermal conductivity silicone to fix it. In actual tests, the temperature can finally be stabilized at around 55°C, which meets the standard for daily use.

[0037] The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
