Electronic devices and cases

The present invention relates to an electronic device and a casing, in particular to an electronic device and a casing provided with a buckle portion and a limit spring arm.

In a server, expansion cards have many uses, such as image processing, network interface, peripheral device interface, data storage, etc. Users can install expansion cards of the required purpose in the server according to their own needs to expand the functions of the server.

Expansion cards include display cards, network cards, smart network cards, etc. Taking smart network cards as an example, smart network cards are usually installed in the chassis through die-cast frames and rails. Among them, the rails are usually fixed to the chassis through nails or mushroom-head rivets. However, the manufacturing cost of the die-cast frame is high. In addition, fixing the rails with nails or mushroom-head rivets will also increase the assembly cost of the rails. Therefore, how to reduce the manufacturing and assembly costs of the frame and rails used for expansion cards is one of the problems that researchers should solve.

The present invention provides an electronic device and a casing to reduce the manufacturing and assembly costs of the electronic device.

The electronic device disclosed in one embodiment of the present invention comprises a housing, a frame, at least one guide rail and an expansion card. The housing comprises at least one first buckle portion and at least one limit groove. The frame can be detachably arranged on the housing and comprises a containing space. The at least one guide rail comprises a main body, at least one second buckle portion and at least one limit spring arm. The at least one second buckle portion and the at least one limit spring arm are connected to the main body. At least one second buckle part can be detachably arranged on the corresponding first buckle part, and can slide relative to the first buckle part, so that at least one second buckle part is buckled on the corresponding first buckle part and at least one limit spring arm can be detachably pressed against the corresponding limit groove, so that at least one guide rail is fixed to the housing, or at least one second buckle part is unfastened from the corresponding first buckle part, so that at least one guide rail is separated from the housing. The expansion card is movably arranged on the main body, and at least part of it is located in the accommodating space.

Another embodiment of the present invention discloses a housing for mounting an expansion card, and includes a housing, a frame member, and at least one guide rail. The housing includes at least one first buckle portion and at least one limit groove. The frame member can be detachably disposed on the housing, and includes a storage space. The storage space is used to accommodate at least part of the expansion card. The at least one guide rail includes a main body, at least one second buckle portion, and at least one limit spring arm. The main body is used for movably mounting the expansion card. The at least one second buckle portion and the at least one limit spring arm are connected to the main body. At least one second buckle portion can be detachably arranged on the corresponding first buckle portion and can slide relative to the first buckle portion, so that the at least one second buckle portion is buckled on the corresponding first buckle portion and the at least one limit spring arm can be detachably pressed against the corresponding limit groove, so that the at least one guide rail is fixed to the shell, or the at least one second buckle portion is disengaged from the corresponding first buckle portion, so that the at least one guide rail is separated from the shell.

According to the electronic device and the housing of the above embodiment, since the rail includes the second buckle part and the limit spring arm, when the user wants to fix the rail to the housing, the second buckle part can be buckled to the first buckle part of the housing, and the limit spring arm can be pressed against the limit groove to limit the rail, so there is no need to use other fasteners to fix the rail to the housing. In this way, the manufacturing and assembly costs of the electronic device can be reduced.

The above description of the content of the present invention and the following description of the implementation method are used to demonstrate and explain the principle of the present invention and provide a further explanation of the scope of the patent application of the present invention.

Please refer to Figures 1 to 4. Figure 1 is a three-dimensional schematic diagram of an electronic device according to an embodiment of the present invention. Figure 2 is a three-dimensional schematic diagram of the electronic device of Figure 1 from another viewing angle. Figure 3 is an exploded schematic diagram of the electronic device of Figure 1. Figure 4 is a cross-sectional schematic diagram of the electronic device of Figure 1.

The electronic device 10 of this embodiment includes a housing 11, a frame member 12, two guide rails 13 and an expansion card 14. The housing 11, the frame member 12 and the two guide rails 13 together constitute a part of a housing. The housing 11 has four first buckle parts 111 and two limit grooves 112. The first buckle part 111 is, for example, a buckle groove. The four first buckle parts 111 and the two limit grooves 112 are, for example, symmetrically distributed. For example, two of the four first buckle parts 111 and one of the two limit grooves 112 are symmetrical with the other two of the four first buckle parts 111 and the other of the two limit grooves 112 along a center line, and the limit grooves 112 on both sides of the center line are, for example, both located between the two first buckle parts 111.

The frame member 12 is formed, for example, by bending sheet metal. The frame member 12 can be detachably disposed on the housing 11 and has a receiving space S. Specifically, the frame member 12 includes a bottom frame 121, two side frames 122, and a top frame 123. One end of the two side frames 122 is respectively connected to two opposite ends of the bottom frame 121. The other end of the two side frames 122 is respectively connected to two opposite ends of the top frame 123. The bottom frame 121 can be detachably disposed on the housing 11. For example, the bottom frame 121 can be detachably riveted to the housing 11. The bottom frame 121, the two side frames 122, and the top frame 123 together surround the receiving space S.

The two guide rails 13 are made of plastic material, for example. The two guide rails 13 are symmetrical along a center line, for example, and can be detachably disposed on the housing 11. Since the four first buckle portions 111, the two limiting grooves 112, and the two guide rails 13 are all symmetrical, and the structure of each first buckle portion 111, the structure of each limiting groove 112, and the structure of each guide rail 13 are the same, the following description is based on the two first buckle portions 111 on one side, the limiting groove 112, and one guide rail 13.

The guide rail 13 includes a main body 131, two second buckle parts 132 and two limit spring arms 133. The two second buckle parts 132 and the two limit spring arms 133 are connected to the main body 131. The second buckle parts 132 are, for example, buckle bumps. One end of the two limit spring arms 133 is connected. The two limit spring arms 133 extend in different directions and are not parallel.

The two second buckle parts 132 are detachably disposed on the two first buckle parts 111, and can slide relative to the two first buckle parts 111, so that the two second buckle parts 132 are respectively buckled on the two first buckle parts 111 and one of the limit spring arms 133 can be detachably pressed against the limit slot 112, so that the guide rail 13 is fixed to the housing 11 to prevent the guide rail 13 from falling off, or the two second buckle parts 132 are respectively unfastened from the two first buckle parts 111, so that the two guide rails 13 are separated from the housing 11. Among them, by providing two limit spring arms 133 extending in different directions and not parallel, when the two guide rails 13 are installed on the housing 11 in different directions, they can be pressed against the limit slot 112 through the limit spring arms 133. That is to say, the two guide rails 13 can be shared in the installation direction.

The expansion card 14 is, for example, a Smart NIC. The expansion card 14 is movably disposed in the main body 131 and is at least partially located in the accommodation space S. The expansion card 14 is, for example, attached to the side frame 122 of the frame member 12 by screws. In addition, the bottom frame 121 has a convex structure 1211. The convex structure 1211 protrudes toward the top frame 123. The expansion card 14 is at least partially supported by the convex structure 1211. In other words, the convex structure 1211 raises the expansion card 14 so that the expansion card 14 can be connected to the connector (not shown) of the external cable.

In this embodiment, since the guide rail 13 includes the second buckle portion 132 and the limit spring arm 133, when the user wants to fix the guide rail 13 to the housing, the second buckle portion 132 can be buckled to the first buckle portion 111 of the housing, and the limit spring arm 133 can be pressed against the limit groove 112 to limit the guide rail 13, so there is no need to use other fasteners to fix the guide rail 13 to the housing. In this way, the assembly cost of the guide rail 13 can be reduced.

In addition, since the frame member 12 is made of sheet metal, no additional mold is required for die-casting, so the manufacturing cost of the frame member 12 can be reduced.

In this embodiment, the bottom frame 121, the two side frames 122 and one side of the top frame 123 are provided with folded edges, but not limited thereto. In this way, the sheet metal frame member 12 can be prevented from scratching the expansion card 14 and the external cable when installing the expansion card 14 and plugging the external cable.

In the present embodiment, the number of guide rails 13 is two, but is not limited thereto. In other embodiments, the number of guide rails may also be only single or more than three.

In this embodiment, the first buckle portion 111 is a buckle groove, and the second buckle portion 132 is a buckle convex block, but it is not limited to this. In other embodiments, the first buckle portion and the second buckle portion can also be reversed. In other words, the first buckle portion can also be a buckle convex block, and the second buckle portion can also be a buckle groove.

In this embodiment, the number of the first buckle parts 111 and the number of the limiting grooves 112 on each side of the housing 11 are two and one respectively, and the number of the second buckle parts 132 and the number of the limiting spring arms 133 on each guide rail 13 are two respectively, but not limited thereto. In other embodiments, the number of the first buckle parts on each side of the housing may be only one or more than three, the number of the limiting grooves on each side of the housing may be multiple, and the number of the second buckle parts and the number of the limiting spring arms on each guide rail may be only one or more than three respectively.

In this embodiment, the bottom frame 121 has a convex hull structure 1211, but is not limited thereto. In other embodiments, the bottom frame may not have a convex hull structure.

Please refer to Figures 5 to 7 together. Figure 5 is a cross-sectional diagram of the frame member in the electronic device of Figure 1 being installed in the housing. Figure 6 is a cross-sectional diagram of the second buckle portion in the electronic device of Figure 1 being arranged on the first buckle portion and not yet buckled. Figure 7 is a cross-sectional diagram of the second buckle portion in the electronic device of Figure 1 being buckled in the first buckle portion.

When the user wants to assemble the two guide rails 13 to the housing 11, as shown in FIG. 5 and FIG. 6, taking one of the guide rails 13 as an example, the guide rail 13 is installed on the housing 11 along direction A. At this time, the two second buckle parts 132 are respectively located at the two first buckle parts 111, and the limit spring arm 133 abuts against the housing 11 and is compressed along direction B to store elastic force. Then, as shown in FIG. 7, the guide rail 13 is moved along direction C, so that the two second buckle parts 132 are respectively buckled with the two first buckle parts 111, and the limit spring arm 133 moves to the limit groove 112 and releases the elastic force, and resets along direction D and abuts against the limit groove 112 to prevent the guide rail 13 from falling off in the reverse direction of direction C. In this way, the assembly of the two guide rails 13 and the housing 11 can be completed.

On the contrary, when the user wants to remove the two guide rails 13 from the housing 11, taking one of the guide rails 13 as an example, the user can press the limit spring arm 133 in the opposite direction of direction D to separate the limit spring arm 133 from the limit slot 112, and release the two second buckle parts 132 from the two first buckle parts 111 in the opposite direction of direction C. Then, the guide rail 13 is removed from the housing 11 in the opposite direction of direction A. In this way, the two guide rails 13 can be removed from the housing 11.

According to the electronic device and the housing of the above embodiment, since the rail includes the second buckle part and the limit spring arm, when the user wants to fix the rail to the housing, the second buckle part can be buckled to the first buckle part of the housing, and the limit spring arm can be pressed against the limit groove to limit the rail, so there is no need to use other fasteners to fix the rail to the housing. In this way, the assembly cost of the rail can be reduced.

In addition, since the frame is made of sheet metal, no additional mold is required for die-casting, so the manufacturing cost of the frame can be reduced.

The electronic device and the housing provided in the present 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, a cloud server, or a vehicle networking server.

Although the present invention is disclosed as above with the aforementioned embodiments, they are not used to limit the present invention. Anyone skilled in similar techniques may make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be subject to the scope of the patent application attached to this specification.
