Description

Technical Field

[0001] The present invention relates to the technical field of industrial computers, and in particular to a modular expandable computer system for industrial use. Background Art

[0002] As is known, there are various industrial computers available today, such as servers, switches, routers, gateways, network attached storage (NAS) computers, application-specific embedded computers, industrial computers, vehicle-mounted computers, security monitoring hosts, gaming hosts, and game consoles. However, the system architectures of industrial computers currently designed by the industry can be broadly categorized into two types. Currently, the simplest way to increase the functionality of a computer device is to add an expansion card. For example, an expansion card containing at least one HDD module and / or at least one SSD module is connected to a corresponding PCIe slot on a NAS computer to expand the storage module capacity of the NAS computer. Another example is connecting an expansion card containing at least one fiber optic transceiver to a corresponding PCIe slot on a network device (such as a POE device or a network switch) to expand the network device's external fiber optic modules.

[0003] However, with the increasing market demand for cloud computing and AI image processing, using expansion boards to expand the functionality of industrial computers is no longer sufficient to meet market demand. Specifically, when the expansion board used to expand the functionality of an industrial computer is a GPU expansion board, if necessary, the user must also expand the computer's storage device (e.g., HDD or SSD) and / or power supply. However, the Electronic Industries Alliance (EIA) defines "U" as the unit of measurement for the main chassis of an industrial computer. Therefore, 1U is 4.445cm, and 2U is 8.89cm. In other words, due to the fixed size of the main chassis of the industrial computer purchased by the user, the user cannot arbitrarily expand the PCIe expansion board (e.g., GPU expansion board, fiber optic network expansion board), storage device (e.g., HDD, SSD), and / or power supply of the industrial computer.

[0004] In summary, it is desirable to design and develop a computer system of specialized specifications, comprising a modular host device, storage device, expansion card device, and power supply device. This would allow users to flexibly add, remove, or repair components in the host device, storage device, expansion card device, and / or power supply device as needed. With this in mind, the inventors of the present invention conducted extensive research and ultimately developed the modular, expandable computer system of the present invention. Summary of the Invention

The first expansion electronic device includes a plurality of storage modules, the second expansion electronic device includes a plurality of expansion card modules, and the third expansion electronic device includes a plurality of power supply modules. Furthermore, the host device is informationally connected to the first expansion electronic device and the second expansion electronic device, respectively. The third expansion electronic device generates power and transmits it to the second expansion electronic device. The power is then transmitted from the second expansion electronic device to the host device, and then from the host device to the first expansion electronic device.

[0006] Based on this design, users can perform the following tasks on the modular expandable computer system of the present invention:

[0007] (1) adding, removing, or repairing storage modules (e.g., hard disk modules or SSD modules) and / or electronic components to the first expandable electronic device;
