[0044] Figures 1A to 1C 1 is a schematic diagram of an electronic device according to an embodiment of the present invention at different viewing angles. It should be noted that in order to clearly illustrate each component, Figure 1C The first back plate 130 and the second back plate 140 are shown transparently. Figures 1A to 1C The electronic device 100 is, for example, a display card, but the present invention does not limit the type of the electronic device 100.

[0045] Figure 2 yes Figure 1C Exploded diagram of an electronic device. Figure 1C and Figure 2The electronic device 100 includes a circuit board 110, an expansion card 120, a first back plate 130, and a second back plate 140. The circuit board 110 includes a back surface 111 and a slot 113 located on the back surface 111. The expansion card 120 is detachably disposed in the slot 113. The first back plate 130 is disposed beside the back surface 111 of the circuit board 110 and includes a through hole 131 corresponding to the expansion card 120. The second back plate 140 is detachably disposed on the first back plate 130 and is located in the through hole 131. The second back plate 140 covers the expansion card 120.

[0046] As described above, the electronic device 100 of the present invention is configured such that when the second back plate 140 is removed from the first back plate 130, the user can remove the expansion card 120 through the through opening 131 of the first back plate 130. This design enables the electronic device 100 to have an expansion function and provides convenience for the user when replacing the expansion card 120.

[0047] In this embodiment, the expansion card 120 is, for example, a solid state drive (SSD), but is not limited thereto.

[0048] like Figure 1C As shown, when the second back plate 140 is disposed on the first back plate 130, the first back plate 130 and the second back plate 140 are coplanar. Accordingly, the electronic device 100 of this embodiment has a relatively simple overall appearance.

[0049] like Figure 1C As shown, the projection of the expansion card 120 on the back surface 111 is within the range of the projection of the through opening 131 on the back surface 111, that is, the overall size of the expansion card 120 is smaller than the size of the through opening 131, and this design allows the expansion card 120 to pass through the through opening 131 when being disassembled. Accordingly, when the user disassembles the expansion card 120, the user only needs to remove the second back plate 140 from the first back plate 130, without removing the first back plate 130. This design allows the user to replace the expansion card 120 through simple steps, which can improve the convenience of the user.

[0050] In this embodiment, the long sides of the inner contour of the through opening 131 are two parallel straight lines, and the short sides include a plurality of bends. However, the inner contour shape of the through opening 131 is not limited to that shown in the figure, and the inner contour shape of the through opening 131 can be any shape that allows the expansion card 120 to pass through.

[0051] Figure 3A yes Figure 2 A partially enlarged schematic diagram of the first back plate, the second back plate and the fixing member. Figure 3B yes Figure 2 A schematic diagram of the first back plate, the second back plate and the fixing member at another viewing angle. Figure 3C yes Figure 3BThe second backplane is arranged on the first backplane. FIG. 3A to FIG. 3C The electronic device 100 further includes a fixing member 150, and the second back plate 140 includes a first end 145 and a second end 147 opposite to each other and a decorative plate body 149. When the second back plate 140 is disposed on the first back plate 130, the first end 145 and the second end 147 correspond to the two short sides of the through opening 131, and the outer contour of the decorative plate body 149 corresponds to the inner contour of the through opening 131.

[0052] In detail, Figure 4 yes Figure 1C Please refer to the cross-sectional diagram of the electronic device. Figure 3A , Figure 3B and Figure 4 Specifically, the first back plate 130 includes a first positioning portion 133 located at the edge and extending toward the circuit board 110. The first positioning portion 133 includes a side hole 1331 ( Figure 3A ), the side hole 1331 is a through hole and takes the axial direction A as the axis. Figure 4 The second back plate 140 includes a second positioning portion 141 close to the first end 145 and extending toward the circuit board 110. The second positioning portion 141 includes a screw hole 1411. The screw hole 1411 also takes the axial direction A as the axis. Accordingly, the user can make the fixing member 150 pass through the side hole 1331 along the axial direction A to be screwed to the screw hole 1411 of the second back plate 140, thereby fixing the second back plate 140. In this embodiment, the fixing member 150 is, for example, a screw, but is not limited thereto.

[0053] It should be noted that the method of fixing the second back panel 140 by the fixing member 150 is not limited to the above. In other embodiments, the fixing member can also fix the second back panel by fixing it to the side hole and resting against the edge of the second back panel. The present case does not limit the method of fixing the second back panel by the fixing member.

[0054] Please refer to Figure 3B and Figure 4 The first back plate 130 further includes a first engaging portion 135 located next to the through hole 131, and the second back plate 140 includes a second engaging portion 143 close to the second end 147 and corresponding to the first engaging portion 135. The second engaging portion 143 is bent and extended from the inner surface of the decorative plate body 149. Figure 4 As shown, when the second back plate 140 is disposed on the first back plate 130 , the second engaging portion 143 of the second back plate 140 is engaged with the first engaging portion 135 of the first back plate 130 , and the second engaging portion 143 is located between the first engaging portion 135 and the circuit board 110 .

[0055] Figure 5 Show Figure 1C The circuit board and the first backplane of the electronic device. Figure 1C and Figure 5 When the user places the expansion card 120 and the second backplane 140 in a Figure 5 When installing the circuit board 110 and the first back plate 130 shown in FIG. 1 , first, the expansion card 120 is placed in the slot 113 of the circuit board 110. Next, the second engaging portion 143 of the second back plate 140 is engaged with the first engaging portion 135 of the first back plate 130, and the decorative plate body 149 is placed in the through opening 131, so that the second back plate 140 and the first back plate 130 are coplanar. Finally, the fixing member 150 is passed through the side hole 1331 passing through the first back plate 130 along the axial direction A to be screwed to the screw hole 1411 of the second back plate 140, thereby fixing the second back plate 140 to the first back plate 130. The installation of the expansion card 120 and the second back plate 140 is completed.

[0056] In summary, the electronic device of the present invention includes a circuit board, an expansion card, a first back plate and a second back plate. The first back plate is disposed on the circuit board and the second back plate is detachably disposed on the first back plate. When the second back plate is disposed on the first back plate, the second back plate covers the expansion card and the first back plate and the second back plate are coplanar. When the second back plate is removed from the first back plate, the user can remove and install the expansion card through the through-hole of the first back plate. Such a design can enable the electronic device to have an expansion function and the user can have convenience when replacing the expansion card.
