[0001] 1. Field of the Invention

[0002] The invention relates to an electronic device and a riser card rotating module and, more particularly, to a riser card rotating module allowing an expansion card to be attached or detached conveniently and rapidly and an electronic device equipped with the riser card rotating module.

[0003] 2. Description of the Prior Art

[0004] As technology advances and develops, computers are considered a necessity by a lot of people in their daily lives. To provide various functions for the computer, a main board of the computer usually has a plurality of expansion slots for installing a plurality of expansion cards such as sound card, graphics card, network card and so on, so as to enhance additional functions. However, as the computer function expands, the size of the expansion card also increases, such that the expansion cards installed in limited space may interfere with each other. At this time, a riser card can be inserted into the expansion card of the main board along a direction perpendicular to the main board and then the expansion card can be inserted into an adapter slot of the riser card along a direction parallel to the main board. Since the operation space in the computer casing is limited, it is inconvenient to attach/detach the expansion card to/from the riser card along the direction parallel to the main board.

SUMMARY OF THE INVENTION

[0005] The invention provides a riser card rotating module allowing an expansion card to be attached or detached conveniently and rapidly and an electronic device equipped with the riser card rotating module, so as to solve the aforesaid problems.

[0006] According to an embodiment of the invention, a riser card rotating module is disposed adjacent to an expansion slot and comprises a guide plate, a fixing plate, a riser card, a first pivot member and a second pivot member. The guide plate has a first guide rail and a second guide rail, wherein the first guide rail and the second guide rail communicate with each other to form a T-shape, the first guide rail is parallel to a plug-unplug direction of the expansion slot, and the second guide rail is perpendicular to the plug-unplug direction of the expansion slot. The riser card is fixed on the fixing plate and has an electric connector. An end of the first pivot member is fixed on the fixing plate and another end of the first pivot member is movably disposed on the guide plate. An end of the second pivot member is fixed on the fixing plate and another end of the second pivot member is movably disposed on the guide plate. When the electric connector of the riser card is inserted into the expansion slot, the first pivot member and the second pivot member are located in the first guide rail and located at opposite sides of the second guide rail. When the fixing plate drives the riser card to move away from the expansion slot to detach the electric connector from the expansion slot, the first pivot member and the second pivot member move away from the expansion slot along the first guide rail. When the second pivot member moves to an intersection of the first guide rail and the second guide rail, the second pivot member is capable of moving from the first guide rail into the second guide rail and driving the first pivot member to move toward the expansion slot along the first guide rail, so as to rotate the riser card.

[0007] According to another embodiment of the invention, an electronic device comprises a casing, a main board and a riser card rotating module. The casing has a back plate. The main board is disposed in the casing and has an expansion slot. The riser card rotating module is disposed in the casing and adjacent to the expansion slot. The riser card rotating module comprises a guide plate, a fixing plate, a riser card, a first pivot member and a second pivot member. The guide plate is fixed on the back plate. The guide plate has a first guide rail and a second guide rail, wherein the first guide rail and the second guide rail communicate with each other to form a T-shape, the first guide rail is parallel to a plug-unplug direction of the expansion slot, and the second guide rail is perpendicular to the plug-unplug direction of the expansion slot. The guide plate is located between the fixing plate and the back plate. The riser card is fixed on the fixing plate and has an electric connector. An end of the first pivot member is fixed on the fixing plate and another end of the first pivot member is movably disposed on the guide plate. An end of the second pivot member is fixed on the fixing plate and another end of the second pivot member is movably disposed on the guide plate. When the electric connector of the riser card is inserted into the expansion slot, the first pivot member and the second pivot member are located in the first guide rail and located at opposite sides of the second guide rail. When the fixing plate drives the riser card to move away from the expansion slot to detach the electric connector from the expansion slot, the first pivot member and the second pivot member move away from the expansion slot along the first guide rail. When the second pivot member moves to an intersection of the first guide rail and the second guide rail, the second pivot member is capable of moving from the first guide rail into the second guide rail and driving the first pivot member to move toward the expansion slot along the first guide rail, so as to rotate the riser card.

[0008] As mentioned in the above, when a user wants to attach/detach an expansion card to/from the riser card, the user needs to operate the fixing plate to drive the riser card to move away from the expansion slot to detach the electric connector from the expansion slot and then operates the fixing plate to drive the second pivot member to move from the first guide rail into the second guide rail and drive the first pivot member to move toward the expansion slot along the first guide rail, such that the riser card can be rotated from a state perpendicular to the main board to another state parallel to the main board. Accordingly, the user can attach/detach the expansion card to/from the riser card in a direction perpendicular to the main board conveniently and rapidly.

[0023] In this embodiment, the casing 10 has a back plate 100. The main board 12 is disposed in the casing 10 and has an expansion slot 120. The riser card rotating module 14 is dispose in the casing 10 and adjacent to the expansion slot 120. The riser card rotating module 14 comprises a guide plate 140, a fixing plate 142, a riser card 144, a first pivot member 146 and a second pivot member 148. The guide plate 140 is fixed on the back plate 100 and has a first guide rail 1400 and a second guide rail 1402, wherein the first guide rail 1400 and the second guide rail 1402 communicate with each other to form a T-shape, the first guide rail 1400 is parallel to a plug-unplug direction A of the expansion slot 120, and the second guide rail 1402 is perpendicular to the plug-unplug direction A of the expansion slot 120, as shown in FIG. 3.

[0024] An end of the first pivot member 146 is fixed on the fixing plate 142 and another end of the first pivot member 146 is movably disposed on the guide plate 140. An end of the second pivot member 148 is fixed on the fixing plate 142 and another end of the second pivot member 148 is movably disposed on the guide plate 140. In this embodiment, the first pivot member 146 may comprise a first screw 1460, a first washer 1462 and a first screw nut 1464 and the second pivot member 148 may comprise a second screw 1480, a second washer 1482 and a second screw nut 1484. Furthermore, the fixing plate 142 may have a first hole 1420 and a second hole 1422. To assemble the riser card rotating module 14, the first screw 1460 passes through the first guide rail 1400, the first washer 1462 and the first hole 1420 in sequence and the first screw nut 1464 is fixed on a thread end of the first screw 1460, such that the fixing plate 142 is clamped and fixed between a neck portion of the first screw 1460 and the first screw nut 1464, and a head portion of the first screw 1460 and the first washer 1462 are capable of sliding at opposite sides of the first guide rail 1400. Similarly, the second screw 1480 passes through the first guide rail 1400, the second washer 1482 and the second hole 1422 in sequence and the second screw nut 1484 is fixed on a thread end of the second screw 1480, such that the fixing plate 142 is clamped and fixed between a neck portion of the second screw 1480 and the second screw nut 1484, and a head portion of the second screw 1480 and the second washer 1482 are capable of sliding at opposite sides of the first guide rail 1400.

[0025] As shown in FIG. 4, after fixing the guide plate 140 on the back plate 100, the guide plate 140 is located between the fixing plate 142 and the back plate 100. Furthermore, the riser card 144 is fixed on the fixing plate 142 and has an electric connector 1440. In practical applications, the electric connector 1440 maybe an edge connector (i.e. so-called gold finger), which can be inserted into the expansion slot 120 of the main board 12, so as to form electric connection. Moreover, as shown in FIG. 1, the riser card 144 further has adapter slots 1440 for receiving an expansion card 3, wherein the expansion card 3 may be a sound card, a graphics card, a network card and so on according to practical applications. It should be noted that the number of the adapter slots 1440 of the riser card 144 may be determined according to practical applications.

[0026] As shown in FIG. 5, when the electric connector 1440 of the riser card 144 is inserted into the expansion slot 120, the first pivot member 146 and the second pivot member 148 are located in the first guide rail 1400 and located at opposite sides of the second guide rail 1402. At this time, since the riser card 144 is fixed by the expansion slot 120, the first pivot member 146 and the second pivot member 148 cannot move along the first guide rail 1400. When a user wants to detach the expansion card 3 from the riser card 144 or attach another expansion card (not shown) to the riser card 144, the user can operate the fixing plate 142 to drive the riser card 144 to move away from the expansion slot 120 in a direction A1 (as shown in FIG. 6), so as to detach the electric connector 1440 from the expansion slot 120. As shown in FIG. 6, when the fixing plate 142 drives the riser card 144 to move away from the expansion slot 120 in the direction A1 to detach the electric connector 1440 from the expansion slot 120, the first pivot member 146 and the second pivot member 148 will move away from the expansion slot 120 along the first guide rail 1400 in the direction A1 simultaneously.

[0027] As shown in FIGS. 6 and 7, when the second pivot member 148 moves to an intersection of the first guide rail 1400 and the second guide rail 1402, the second pivot member 148 can move from the first guide rail 1400 into the second guide rail 1402 in a direction A2 and drive the first pivot member 146 to move toward the expansion slot 120 along the first guide rail 1400 in a direction A3, so as to rotate the riser card 144 in a direction A4. In this embodiment, since the first guide rail 1400 and the second guide rail 1402 communicate with each other to form the T-shape, i.e. the first guide rail 1400 and the second guide rail 1402 are perpendicular to each other, the riser card 144 can be rotated with 90 degrees from a state perpendicular to the main board 12 (as shown in FIG. 6) to another state parallel to the main board 12 (as shown in FIG. 8).

[0028] When the second pivot member 148 moves along the second guide rail 1402 to drive the first pivot member 146 to move to the intersection of the first guide rail 1400 and the second guide rail 1402 (as shown in FIG. 8), the first pivot member 146 is capable of moving from the first guide rail 1400 into the second guide rail 1402. Accordingly, when the first pivot member 146 moves to the intersection of the first guide rail 1400 and the second guide rail 1402, the user can further operate the fixing plate 142 to drive the first pivot member 146 and the second pivot member 148 to move in the direction A2, such that the first pivot member 146 and the second pivot member 148 both are located in the second guide rail 1402, as shown in FIGS. 8 and 9. Since the first pivot member 146 and the second pivot member 148 both are located in the second guide rail 1402, the fixing plate 142 is restrained from moving in a direction perpendicular to the main board 12. At this time, the user can detach the expansion card 3 from the riser card 144 or attach another expansion card (not shown) to the riser card 144 in the direction perpendicular to the main board 12 conveniently and rapidly.

[0029] After detaching the expansion card 3 from the riser card 144 or attaching another expansion card (not shown) to the riser card 144, the user can operate the fixing plate 142 to drive the first pivot member 146 and the second pivot member 148 to move in the direction A5, such that the first pivot member 146 moves to the intersection of the first guide rail 1400 and the second guide rail 1402, as shown in FIGS. 8 and 9. When the first pivot member 146 moves to the intersection of the first guide rail 1400 and the second guide rail 1402, the first pivot member 146 is capable of moving away from the expansion slot 120 along the first guide rail 1400 in the direction A1 and driving the second pivot member 148 to move along the second guide rail 1402 in the direction A5, so as to rotate the riser card 144 in the direction A6, as shown in FIGS. 7 and 8. When the second pivot member 148 moves into the first guide rail 1400 along the second guide rail 1402, the user can push the fixing plate 142 toward the expansion slot 120 in the direction A3, so as to insert the electric connector 1440 of the riser card 144 into the expansion slot 120, as shown in FIGS. 5 and 6. Accordingly, the expansion card can be attached or detached easily.

[0030] Referring to FIGS. 10 and 11, FIG. 10 is a perspective view illustrating a riser card rotating module 14' according to another embodiment of the invention and FIG. 11 is a perspective view illustrating the fixing plate 142 shown in FIG. 10 after rotating with 90 degrees. The main difference between the riser card rotating module 14' and the aforesaid riser card rotating module 14 is that the riser card rotating module 14' further comprises a resilient member 150, wherein opposite ends of the resilient member 150 are fixed on a fixing portion 1404 of the guide plate 140 and a fixing portion 1424 of the fixing plate 142. In this embodiment, the resilient member 150 may be an extension spring. When the first pivot member 146 and the second pivot member 148 are located in the first guide rail 1400 (as shown in FIG. 5), the resilient member 150 is stretched, as shown in FIG. 10. When the second pivot member 148 moves to the intersection of the first guide rail 1400 and the second guide rail 1402 (as shown in FIG. 6), an elastic force generated by the resilient member 150 will drive the second pivot member 148 to move into the second guide rail 1402, such that the riser card 144 will rotate with 90 degrees to the state shown in FIG. 11. In other words, the invention may further use the resilient member 150 to assist the riser card 144 in rotating more smoothly.

[0031] As mentioned in the above, when a user wants to attach/detach an expansion card to/from the riser card, the user needs to operate the fixing plate to drive the riser card to move away from the expansion slot to detach the electric connector from the expansion slot and then operates the fixing plate to drive the second pivot member to move from the first guide rail into the second guide rail and drive the first pivot member to move toward the expansion slot along the first guide rail, such that the riser card can be rotated from a state perpendicular to the main board to another state parallel to the main board. Accordingly, the user can attach/detach the expansion card to/from the riser card in a direction perpendicular to the main board conveniently and rapidly.

[0032] Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
