DETAILED DESCRIPTION OF THE INVENTION
To facilitate understanding of the object, characteristics and effects of this present disclosure, embodiments together with the attached drawings for the detailed description of the present disclosure are provided.
Referring to FIG. 1, there is shown a perspective view of a computation device according to an embodiment of the present disclosure. In this embodiment, the computation device 1 is, for example, a personal computer or an industrial computer and comprises an expandable host 100 and an expansion module 200. The expandable host 100 and expansion module 200 can be freely connected and separated. Preferably, the computation device 1 further comprises a mounting support 300. The mounting support 300 is, for example, adapted to mount the expandable host 100 and expansion module 200 at a specific position on a wall or a metal board. The mounting support 300 is fixedly disposed at the expandable host 100 and expansion module 200 and comprises a fixing portion 310. The fixing portion 310 protrudes relative to the casings of the expandable host 100 and expansion module 200 and forms a plurality of fastening-oriented holes. Users fix the expandable host 100 and expansion module 200 to the mounting support 300 and then allow the expandable host 100 and expansion module 200 to be penetratingly disposed at the holes on the fixing portion 310 with fastening elements, such as screws or rivets; hence, the computation device 1 is fastened to the specific position, thereby enhancing ease of use.
Refer to FIG. 2 through FIG. 4. FIG. 2 is a front view of an expandable host of FIG. 1. FIG. 3 is a cross-sectional view taken along line X-X of FIG. 2. FIG. 4 is an enlarged view of area A of FIG. 3. As shown in the diagrams, in this embodiment, the expandable host 100 comprises a host casing 110, a host circuit board 120, a computation unit 130 and an electrical unit 140, wherein the host circuit board 120 is disposed in the host casing 110; computation unit 130 is, for example, a central processing unit (CPU) and disposed on the host circuit board 120; electrical unit 140 is, for example, a power supplying unit (PSU) disposed in host casing 110 and electrically connected to host circuit board 120 to rectify and transform an external power into current and voltage suitable for being inputted to the electronic components of the expandable host 100. Preferably, the expandable host 100 further comprises a heat dissipation unit 150, wherein the heat dissipation unit 150 is, for example, a module (comprising fans and fins) disposed in host casing 110 and electrically connected to electrical unit 140, such that heat generated as a result of the operation of constituent components of the expandable host 100 is released to the outside of the host casing 110.
The expandable host 100 either works independently or integrates with the expansion module 200 to attain robust work performance or computation capability. Referring to FIG. 2 and FIG. 3, the host casing 110 has an opening 112, and a slot 122 is formed on host circuit board 120. The slot 122 receives an electronic component and is aligned with the opening 112. Thus, to put the computation device 1 into use, the expansion module 200 is inserted into the slot 122 of the expandable host 100 via the opening 112, such that the expandable host 100 and expansion module 200 are coupled together to enhance work performance or computation capability. To reduce power output or perform maintenance or inspection of the expansion module 200, users remove the expansion module 200 from the expandable host 100, such that the expandable host 100 operates independently and thus prevents the production line from being put aside or grinding to a halt, minimizes financial loss, and simplifies a maintenance or inspection process.
Preferably, at least one fastening hole is formed on the host casing 110 and positioned proximate to the rim of the opening 112. There is a height difference between the opening 112 and the host casing 110. To remove the expansion module 200 from the expandable host 100, users fasten a cover board corresponding in size and shape to the opening 112 to the opening 112 with some fastening elements, such as screws or rivets, such that not only is ambient dust unlikely to intrude into the host casing 110 to otherwise contaminate or damage internal components, but the host casing 110 also has a neat appearance.
Referring to FIG. 2, the slot 122 comprises a first bus 122a and a second bus 122b. The first bus 122a and first bus 122b are of equal width or different widths. This embodiment is exemplified by the second bus 122b being of greater width than the first bus 122a. With the expansion module 200 being inserted into the slot 122, its electronic components need high-power power supply. To this end, the expandable host 100 transmits data signals and power to electronic components of expansion module 200 via first bus 122a and second bus 122b, respectively. Thus, one of first bus 122a and second bus 122b is electrically connected to computation unit 130, whereas the other is electrically connected to electrical unit 140. In this embodiment, first bus 122a is electrically connected to computation unit 130, and second bus 122b is electrically connected to electrical unit 140. Thus, when expansion module 200 is inserted into slot 122, first bus 122a receives data signals from computation unit 130 and sends the data signals, whereas second bus 122b receives power supply from electrical unit 140. Therefore, two different types of electrical signals do not interfere with each other, and their transmission efficiency increases.
Referring to FIG. 4, slot 122 is fastened to host circuit board 120 with a fastening element 124. The fastening element 124 is, for example, a rivet. To provide direction guide and touch feedback required for users to insert the component into slot 122, expandable host 100 further comprises a guide portion 160. The guide portion 160 is, for example, a guide rail made of a resilient metal plate disposed in host casing 110, connected to opening 112 and extended toward slot 122. When users insert the electronic components of expansion module 200 into opening 112, the lower ends of the electronic components are blocked by the guide portion 160 and thus firmed inserted into slot 122 along the extension direction.
Refer to FIG. 5 and FIG. 6. FIG. 5 is a lateral view of an expansion module of FIG. 1. FIG. 6 is a cross-sectional view taken along line Y-Y of FIG. 5. As shown in the diagrams, in this embodiment, the expansion module 200 comprises an expansion casing 210, an expansion circuit board 220 and an expansion unit 230, wherein the expansion circuit board 220 is penetratingly disposed at the expansion casing 210; expansion unit 230 is, for example, a display card and comprises a graphic processing unit (GPU) disposed in expansion casing 210 and electrically connected to expansion circuit board 220. Preferably, expansion module 200 further comprises an expansion unit support 240, wherein the expansion unit support 240 is disposed in the expansion casing 210 and fixedly disposed at or slidably disposed at expansion circuit board 220 to adjust the position of expansion unit 230 relative to expansion circuit board 220. The expansion unit 230 is mounted on expansion unit support 240.
The expansion module 200 is inserted into slot 122 of expandable host 100, and thus expandable host 100 has robust performance. Referring to FIG. 5 and FIG. 6, expansion circuit board 220 comprises an insertion portion 222, wherein the insertion portion 222 protrudes from the expansion casing 210 and comprises a first terminal 222a and a second terminal 222b. The first terminal 222a and second terminal 222b correspond in function and size to first bus 122a and second bus 122b, respectively. Thus, in this embodiment, data signals inputted and outputted by expansion unit 230 are transmitted by the first terminal 222a, whereas second terminal 222b transmits power to expansion unit 230. The second terminal 222b is of a greater width than first terminal 222a. When users insert insertion portion 222 into slot 122 via opening 112, expansion unit 230 receives high-power power supply (500 W in this embodiment) from electrical unit 140 via second bus 122b and second terminal 222b and receives data signals from computation unit 130 via first bus 122a and first terminal 222a. The data signals are sent back to computation unit 130 after being computed by electronic components, such as a processor and memory inside expansion unit 230. Therefore, expandable host 100 has robust and diverse performance.
The expansion module 200 enhances the computing and processing capability of expandable host 100. In this embodiment, the expansion module 200 further comprises an expansion computation unit 250 and an expansion heat dissipation unit 260. The expansion computation unit 250 is, for example, a central processing unit and is disposed in the expansion casing 210. The expansion heat dissipation unit 260 is, for example, a fan set. The expansion computation unit 250 and expansion heat dissipation unit 260 are electrically connected to expansion circuit board 220. When users insert insertion portion 222 into slot 122, both expansion computation unit 250 and expansion heat dissipation unit 260 receive data signals and power from expandable host 100, assisting expandable host 100 in computation and assisting expansion module 200 in heat dissipation. In a variant embodiment, expansion computation unit 250 is replaced with a storage medium, such as flash memory and hard disk drive, and the present disclosure is not limited thereto.
Use of the computation device 1 in this embodiment is described below. Referring to FIG. 7, there is shown a schematic view of constituent elements of the computation device of FIG. 1. As shown in the diagrams, to enhance the display performance or computation performance of expandable host 100, expandable host 100 and expansion module 200 approach each other in first direction D1 and second direction D2 of FIG. 7, respectively, and insertion portion 222 of expansion circuit board 220 is inserted into slot 122 via opening 112. After expandable host 100 and expansion module 200 have been completely and firmly coupled together, the mounting support 300 is moved in third direction D3 and thus fixedly disposed at the expandable host 100 and expansion module 200 with fastening elements, such as screws or rivets. Thus, computation unit 130, electrical unit 140 and expansion unit 230 are disposed in the two independent casings. When expandable host 100 needs expansion module 200 of a different specification, or when internal components of expansion module 200 require inspection or maintenance, only expansion module 200 needs to be removed from expandable host 100 to keep the production line operating continuously and render computation device 1 flexible in terms of application.
While the present disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the present disclosure set forth in the claims.
