Description

Technical Field

[0001] This utility model relates to the field of network communication technology, and in particular to a smart lightweight cloud box that integrates a USB hub and a 100M Ethernet port. Background Technology

[0002] As a commonly used device in edge computing and industrial IoT scenarios, smart lightweight cloud boxes need to simultaneously meet the requirements of network connectivity and expansion of multiple peripherals. However, existing smart lightweight cloud boxes often suffer from low functional integration: most products only have network access or basic data processing capabilities. If multiple USB devices such as mice, keyboards, and USB flash drives need to be connected, an additional USB hub is required, which not only increases the purchase cost of the equipment but also leads to messy desktop cabling and occupies more space. Some products that integrate USB interfaces often lack a 100M Ethernet port and rely solely on wireless connectivity. In scenarios with high network stability requirements, such as industrial environments, data transmission is easily interrupted due to signal interference. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes an intelligent lightweight cloud box that integrates a USB hub and a 100M Ethernet port.

[0004] This utility model proposes an intelligent lightweight cloud box integrating a USB hub and a 100M Ethernet port, comprising a fixedly connected device housing and a device cover. A circuit board is installed inside the device housing, and the circuit board integrates a USB 3.0 port, a USB 2.0 port, an Ethernet port, a main control chip, and a USB hub chip. One pin of the main control chip is connected to a USB 3.0 port, and a pin of the USB hub chip is connected to one of the USB 2.0 ports to expand to several USB 2.0 ports. Another pin of the main control chip is connected to the Ethernet port.

[0005] Furthermore, several heat dissipation holes are provided around the side of the device housing to improve the heat dissipation performance of the device.

[0006] Furthermore, the circuit board also integrates an EMMC module, an LPDDR4 module, an infrared module, a wireless communication module, a power supply interface, and an HDMI module.

[0007] Furthermore, the wireless communication module is configured as a Bluetooth or WIFI module, and the power supply interface is configured as a Type-C interface.

[0008] Furthermore, the circuit board also integrates a power contact switch, a status indicator light, and a network indicator light. The upper surface of the device cover is provided with a power button, a first window, and a second window, and the power contact switch, status indicator light, and network indicator light correspond to the power button, the first window, and the second window.

[0009] Furthermore, the Ethernet port is configured as a 100M RJ45 Ethernet port.

[0010] The beneficial effects of this utility model are as follows: By integrating USB 3.0, USB 2.0, a 100M Ethernet port, and a USB HUB chip on the circuit board, the expansion function of one USB 3.0 interface and multiple USB 2.0 interfaces can be directly realized without the need for an additional USB HUB expander, effectively reducing equipment purchase costs, avoiding messy desktop wiring, and reducing space occupation. At the same time, the 100M Ethernet port and the wireless communication module form a wired + wireless dual network connection mode. In edge computing scenarios such as industrial IoT where network stability requirements are high, it can avoid the problem of data transmission interruption caused by signal interference when using a single wireless connection, meet the dual needs of the device for network connectivity and expansion of multiple peripherals, and improve ease of use and network stability.

[0013] Reference Figure 1-5This utility model proposes an intelligent lightweight cloud box integrating a USB hub and a 100M Ethernet port, including a device body 1 and a device cover 2, which are fixedly connected to form a complete device shell. The overall dimensions of the shell are 110mm long × 55mm wide × 15mm high. The compact size design allows it to be hidden in small spaces such as behind a monitor, greatly reducing space occupation. The device body 1 has several heat dissipation holes 11 around its side. During device operation, the heat dissipation holes 11 can accelerate the air circulation inside and outside the box, and timely dissipate the heat generated by the circuit board 3 and various modules during operation, effectively avoiding the impact of excessive temperature on the stability of device operation, and significantly improving the heat dissipation performance and service life of the device. The upper surface of the device cover 2 is respectively provided with a power button 21, a first window 22 and a second window 23. These structures cooperate with the corresponding components on the circuit board 3 to realize the device control and status observation functions.

[0014] Inside the device housing 1, a circuit board 3 is installed. The circuit board 3 adopts a 4-layer board design, with dimensions of 101mm in length × 46mm in width × 1.2mm in thickness. The reasonable layer layout and size design can not only meet the integration and installation requirements of various functional modules, but also ensure the stability of circuit signal transmission. The circuit board 3 integrates various modules and interfaces that realize the core functions of the device, including USB 3.0 31, USB 2.0 32, Ethernet port 33, main control chip 34, USB HUB chip 314, eMMC module 35, LPDDR4 module 36, infrared module 37, wireless communication module 38, power supply interface 39, HDMI module 310, power contact switch 311, status indicator light 312, and network indicator light 313.

[0015] Each pin of the main control chip 34 is connected to different modules and interfaces to achieve coordinated control and data processing of the entire device. One pin of the main control chip 34 is directly connected to USB 3.0 31 to ensure that USB 3.0 31 has high-speed data transmission capability, which can meet the data read and write requirements of high-speed storage devices such as USB flash drives. Another pin is connected to USB HUB chip 314, which is in turn connected to one of USB 2.0 32. Through the expansion function of USB HUB chip 314, several additional USB 2.0 32 can be added, ultimately forming a USB HUB structure of "one USB 3.0 + multiple USB 2.0", which can connect multiple USB devices such as mice, keyboards, and USB flash drives at the same time without the need to purchase additional USB HUB expansion equipment. At the same time, the third pin of the main control chip 34 is connected to Ethernet port 33. Ethernet port 33 is designed for 100M speed and can be connected to the upper-level gateway through a network cable to realize wired network connection of the device. Together with the wireless communication module 38 on the circuit board 3, a dual network connection mode is formed. The wireless communication module 38 can be configured as a Bluetooth module or a WIFI module. If it is a WIFI module (model BL-M5621DS1 optional, supporting WIFI5), it is connected to the main control chip 34 through the SDIO interface. If it is a Bluetooth module (model BL-M5621DS1 optional, supporting BT5.1), it is connected to the main control chip 34 through the UART interface. Users can flexibly choose wired or wireless methods to enable the device to access the network according to the actual usage scenario, thereby improving the convenience and applicability of the device.

[0016] The EMMC module 35 and the LPDDR4 module 36 together constitute the device's storage and operation support system. The EMMC module 35 (capacity optional 8GB, model such as RS70B08G3S03F) is a solid-state storage device, mainly used to store the device's Android operating system, boot program, and various system data, providing basic data support for device startup and operation. The LPDDR4 module 36 (capacity optional 2GB, model such as RS512M32LO4D1B) is a dynamic storage device. After the device starts up, the boot program and running data stored in the EMMC module 35 will be loaded into it, providing high-speed data cache space for program operation, ensuring smooth device operation, and avoiding stuttering problems caused by data read delays.

[0017] The power supply interface 39 is a Type-C interface, compatible with DC5V2A input specifications. Connecting an external power adapter to the power supply interface 39 provides a stable operating voltage and current for the entire device, ensuring the normal operation of each module. The HDMI module 310 is connected to the HDMI TX end of the main control chip 34, and can output 4K resolution audio and video signals through the HDMI interface. After connecting the device to display devices such as 4K monitors, the device's operating interface and audio and video content can be clearly displayed, meeting users' needs for high-definition display. The infrared module 37 is electrically connected to the main control chip 34, and can receive control signals from an external infrared remote control and transmit the signals to the main control chip 34. The main control chip 34 performs corresponding operations based on the received signals, realizing the infrared remote control function of the smart cloud box and improving the flexibility of device operation.

[0018] In addition, the power contact switch 311, status indicator 312, and network indicator 313 on the circuit board 3 correspond to the power button 21, the first window 22, and the second window 23 on the device cover 2, respectively. When the user presses the power button 21, it will trigger the power contact switch 311 below, realizing the power-on or power-off operation of the device. The status indicator 312 will light up when the device is running, and will indicate whether the device is currently in working or standby mode through different colors or flashing frequencies. The user can intuitively observe the device's operating status through the first window 22. The network indicator 313 is electrically connected to the Ethernet port 33. When the Ethernet port 33 successfully connects to the network and communicates normally, the network indicator 313 will light up or flash in a specific way. The user can quickly judge the network connection status through the second window 23, which is convenient for timely troubleshooting of network faults.

[0019] In practical use, the smart lightweight cloud box is connected to a 4K monitor via an HDMI cable, the two USB 2.0 ports 32 are connected to the mouse and keyboard respectively, and the USB 3.0 port 31 is connected to a USB flash drive. Simultaneously, the Ethernet port 33 is connected to the upstream gateway via a network cable, and the device is powered via the Type-C power interface 39. Pressing the power button 21 starts the device. After startup, the device reads the startup program from the eMMC module 35, verifies and pairs it, and loads it into the LPDDR4 module 36 for operation, displaying the operation menu interface. Users can operate the device using a mouse, keyboard, or infrared remote control. The device receives network signals via the Ethernet port 33 or the wireless communication module 38, processes them through the main control chip 34, decrypts the audio and video signals, and outputs them to the monitor via the HDMI module 310. It can also interact with external USB devices via the USB interface, perfectly solving the problem of traditional smart lightweight cloud boxes requiring additional adapters and HUB expansion devices. It is especially suitable for scenarios requiring multi-device connectivity and network management, such as industrial IoT and edge computing.
