Description

Electronic components and housing components

The present invention relates to an electronic assembly and a housing assembly, and in particular to an electronic assembly comprising a display card module and an adapter card module, and a housing assembly for arranging the display card and the adapter card.

Generally speaking, to achieve high space utilization, various electronic components are placed very densely in the server case. Therefore, larger electronic components such as graphics cards often require the assistance of an adapter card to be electrically connected to the motherboard.

However, the graphics card module and the riser card module are usually installed in the server chassis in different directions. Therefore, if the riser card module is removed from the chassis before the graphics card module is removed from the chassis, the connectors on the graphics card module and the riser card module may be damaged.

The present invention provides an electronic assembly and a housing assembly including a limiting cover to prevent an adapter card module from being removed from a housing before a display card module is removed from the housing, thereby preventing the connectors on the display card module and the adapter card module from being damaged.

The electronic assembly disclosed in one embodiment of the present invention includes a housing, an adapter card module and a display card module. The adapter card module includes an assembly frame and an adapter card. The assembly frame includes a frame and a handle. The handle includes two mounting parts and an operating part. The operating part is connected to the two mounting parts. The two mounting parts are respectively pivoted on opposite sides of the frame. The adapter card is arranged on the frame. The frame is slidably arranged on the housing along a first mounting direction. The display card module includes a bracket, a display card and a limit cover. The display card is arranged on the bracket and electrically connected to the adapter card. The limit cover is arranged on one side of the bracket. The bracket is slidably arranged on the housing along a second mounting direction. The first mounting direction is different from the second mounting direction. When the bracket is assembled on the housing, the limit cover covers the operating part, preventing the operating part from driving the two mounting parts to pivot relative to the frame, thereby preventing the handle from driving the frame to slide relative to the housing.

Another embodiment of the present invention discloses a housing assembly for accommodating a display card and an adapter card. The housing assembly includes a housing, an assembly frame, a bracket, and a limiting cover. The assembly frame includes a frame and a handle. The handle includes two mounting parts and an operating part. The operating part is connected to the two mounting parts. The two mounting parts are respectively pivoted to opposite sides of the frame. The frame is slidably arranged on the housing along a first mounting direction and is used for accommodating the adapter card. The bracket is slidably arranged on the housing along a second mounting direction and is used for accommodating the display card. The first mounting direction is different from the second mounting direction. The limiting cover is arranged on one side of the bracket. When the bracket is assembled on the housing, the limit cover covers the operating part, preventing the operating part from driving the two mounting parts to pivot relative to the frame, thereby preventing the handle from driving the frame to slide relative to the housing.

According to the electronic assembly and housing assembly disclosed in the aforementioned embodiments, when the bracket is assembled to the housing, the limiting cover covers the operating portion, preventing the operating portion from causing the two mounting portions to pivot relative to the housing, thereby preventing the handle from causing the housing to slide relative to the housing. Therefore, as long as the bracket for the graphics card is assembled to the housing, the housing for the adapter card cannot be removed from the housing. This prevents the adapter card module from being removed from the housing before the graphics card module is removed from the housing, thereby preventing damage to the connectors connecting the graphics card module and the adapter card module.

The following detailed description of the features and advantages of the embodiments of the present invention is sufficient to enable anyone with ordinary skill in the art to understand the technical aspects of the embodiments of the present invention and implement them accordingly. Furthermore, based on the disclosure, patent application, and drawings in this specification, anyone with ordinary skill in the art can easily understand the relevant objectives and advantages of the present invention. The following embodiments further illustrate the concepts of the present invention in detail and are not intended to limit the scope of the present invention in any way.

Please refer to Figures 1 and 2. Figure 1 is a perspective view of an electronic assembly according to an embodiment of the present invention. Figure 2 is an exploded perspective view of the electronic assembly in Figure 1.

In this embodiment, the electronic assembly 10 includes a housing 100, an adapter card module 200, and a display card module 300. The housing 100 includes a fixing bracket 110 and two fixing posts 120. The housing 100 may be, for example, a server housing or a server chassis. Furthermore, the display card module 300 may be, for example, a graphics processing unit (GPU) module, but the present invention is not limited thereto.

In this embodiment, the adapter card module 200 includes an assembly frame 210 and an adapter card 220. The assembly frame 210 includes a frame 211 and a handle 212. The handle 212 includes two mounting portions 213 and an operating portion 214. The operating portion 214 connects the two mounting portions 213. The two mounting portions 213 are pivotally connected to opposite sides of the frame 211. The adapter card 220 is mounted on the frame 211. The frame 211 is slidably mounted on the housing 100 along a first mounting direction D1.

In this embodiment, the graphics card module 300 includes, for example, a bracket 310, a graphics card 320, a retaining cover 330, and a plurality of locking elements 340. The bracket 310 is slidably mounted on the housing 100 along a second mounting direction D2. The first mounting direction D1 is different from the second mounting direction D2. In other words, the frame 211 of the riser card module 200 and the bracket 310 of the graphics card module 300 are mounted on the housing 100 in different directions. For example, in this embodiment, the first mounting direction D1 and the second mounting direction D2 are perpendicular to each other.

In this embodiment, the bracket 310 includes, for example, a base plate 311, two side plates 312, and a support frame 313. The side plates 312 are connected to opposite sides of the base plate 311. The support frame 313 is connected to the side plates 312 and is located on a side of the side plates 312 that is away from the base plate 311. The graphics card 320 is mounted on the base plate 311 and electrically connected to the adapter card 220. The limiting cover 330 is, for example, fixed to a side of the support frame 313 that is away from the base plate 311.

It should be noted that the housing 100 , the assembly frame 210 , the bracket 310 and the limiting cover 330 may be collectively referred to as a housing assembly.

Please refer to Figures 3 to 5. Figure 3 is a partial enlarged view of the three-dimensional view of the adapter card module and the display card module of the electronic assembly in Figure 1. Figure 4 is an upper view of the adapter card module and the display card module in Figure 3. Figure 5 is a three-dimensional exploded view of the adapter card module and the display card module in Figure 3. In detail, in this embodiment, the limiting cover 330 is made of plastic, for example, and includes a mounting plate 331, a connecting plate 332, a limiting plate 333 and a plurality of structural ribs 334. The mounting plate 331 and the limiting plate 333 are respectively connected to opposite sides of the connecting plate 332. The connecting plate 332 is, for example, approximately in the shape of a Chinese character "ㄇ". The mounting plate 331, the connecting plate 332 and the limiting plate 333 together form a limiting space 335 and an opening 336. Opening 336 is connected to limiting space 335. The mounting plate 331 is fixed to a side of the support frame 313 away from the base plate 311. For example, the mounting plate 331 includes a plurality of locking holes 3310. These locking members 340 are respectively locked into these locking holes 3310 to secure the mounting plate 331 and the support frame 313. Structural ribs 334 are located in limiting space 335 and connect the mounting plate 331, the connecting plate 332, and the limiting plate 333 to increase the structural strength of the limiting cover 330. However, the present invention is not limited to this. In other embodiments, the limiting cover may not include structural ribs 334.

Furthermore, in this embodiment, as shown in Figures 4 and 5 , the limiting plate 333 includes, for example, a plurality of clearance holes 3330. These clearance holes 3330 overlap the corresponding locking elements 340 and the locking holes 3310. In other words, these clearance holes 3330 overlap the corresponding locking elements 340 and the locking holes 3310 along the normal direction N of the top surface 3331 of the limiting plate 333 facing away from the mounting plate 331. Note that in Figure 4 , to clearly illustrate the overlap of the clearance holes 3330 with the locking elements 340 and the locking holes 3310, a portion of the operating portion 214 is omitted. In other embodiments, the number of locking elements, locking holes, and clearance holes may all be single. Alternatively, in yet other embodiments, the locking member, the locking hole, and the clearance hole may be omitted, and the limiting cover may be fixed to the supporting plate by welding instead.

In addition, as shown in FIG. 5 , the display card 320 and the riser card 220 are electrically connected in a board-to-board manner, for example, via connectors 321 and 221 .

In addition, please refer to Figure 6, which is a partial enlarged view of the schematic side cross-sectional view of the electronic assembly in Figure 1. In this embodiment, the handle 212 further includes a positioning member 215. The positioning member 215 is disposed on the operating portion 214 and can be detachably engaged with the fixing bracket 110 of the housing 100 to position or release the operating portion 214 relative to the housing 100.

As shown in Figures 1, 2, and 6, when the bracket 310 is assembled to the case 100, the limiting cover 330, for example, covers the operating portion 214 and a grip portion 216 of the positioning member 215, preventing the positioning member 215 from releasing the operating portion 214 relative to the case 100 (i.e., preventing a hook portion 217 of the positioning member 215 from being restrained by the fixing bracket 110). Specifically, the operating portion 214 passes through the opening 336 and is at least partially positioned within the limiting space 335. The limiting plate 333 is located on a side of the operating portion 214 away from the mounting plate 331. This prevents the operating portion 214 from causing the two mounting portions 213 to pivot relative to the frame 211, thereby preventing the handle 212 from causing the frame 211 to slide relative to the case 100.

Please refer to Figures 2, 7, and 8. Figure 7 is a perspective view of the display card module of the electronic assembly in Figure 1 removed from the housing. Figure 8 is a partially enlarged view of the side cross-sectional view of the electronic assembly in Figure 7.

When the bracket 310 is removed from the housing 100 along a first removal direction D3 opposite to the second installation direction D2, the retaining cover 330 no longer covers the operating portion 214 and the gripping portion 216 of the positioning member 215, leaving the operating portion 214 and the gripping portion 216 of the positioning member 215 exposed. Therefore, the gripping portion 216 of the positioning member 215 can be pulled, releasing the operating portion 214 from the housing 100 (i.e., releasing the hook portion 217 of the positioning member 215 from the retaining portion of the fixing bracket 110). In this way, the operating portion 214 can drive the two mounting portions 213 to pivot relative to the frame 211, and then through the cooperation between the handle 212 and the two fixing posts 120 of the case 100, drive the frame 211 to slide relative to the case 100 along a second disassembly direction D4 opposite to the first mounting direction D1 and be removed from the case 100.

According to the electronic assembly and housing assembly disclosed in the aforementioned embodiments, when the bracket is assembled to the housing, the limiting cover covers the operating portion, preventing the operating portion from causing the two mounting portions to pivot relative to the housing, thereby preventing the handle from causing the housing to slide relative to the housing. Therefore, as long as the bracket for the graphics card is assembled to the housing, the housing for the adapter card cannot be removed from the housing. This prevents the adapter card module from being removed from the housing before the graphics card module is removed from the housing, thereby preventing damage to the connectors connecting the graphics card module and the adapter card module.

The electronic components and housing components provided in this embodiment can be applied to, for example, a server host, which can be used for artificial intelligence (AI) computing, edge computing, and can also be used as a 5G server, cloud server, or vehicle network server.

Although the present invention is disclosed above with reference to the aforementioned embodiments, they are not intended to limit the present invention. Anyone skilled in the art may make slight modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the scope of the patent application attached to this specification.
