The present invention relates to an electronic device, in particular to an electronic device with a double-layer motherboard.

Modern society is in an era of rapid development of information technology. Most companies use servers to assist in business processing, such as storing programs, files and data, to improve work efficiency.

Generally speaking, manufacturers will install a double-layer motherboard in the server to further improve the operating efficiency of the server. However, in a server with a double-layer motherboard, when the user wants to replace the electronic components of the lower motherboard, he needs to remove the upper motherboard first, and then assemble the upper motherboard after the electronic components of the lower motherboard are replaced. This makes the steps of replacing electronic components too complicated and causes inconvenience to the user. Therefore, how to improve the convenience of replacing electronic components of the motherboard is one of the problems that researchers should solve.

The present invention provides an electronic device to improve the convenience of replacing electronic components of a motherboard.

The electronic device disclosed in one embodiment of the present invention is used to accommodate two motherboards, and includes a housing, at least one support frame assembly and an upper tray. The housing includes a bottom plate and two side plates. The two side plates are respectively connected to the opposite sides of the bottom plate. The at least one support frame assembly includes at least one fixed support frame and at least one movable support frame. The at least one fixed support frame is fixed to one of the two side plates. The at least one movable support frame can be movably arranged on one of the two side plates and is located on the same side as the at least one fixed support frame. One side of the upper tray is hinged to the at least one movable support frame. The other side of the upper tray can be movably arranged on at least one fixed support frame, so that the upper tray and the at least one movable support frame can move relative to the at least one fixed support frame, and the upper tray can rotate relative to the at least one movable support frame. One of the two motherboards is arranged on the upper tray. The other of the two motherboards is arranged on the bottom plate.

According to the electronic device of the above-mentioned embodiment, since the housing of the electronic device is provided with a fixed support frame and a movable support frame, when the user needs to replace the electronic components of the motherboard arranged on the lower tray, there is no need to remove the upper tray. The lower tray and the motherboard arranged on the lower tray can be exposed by only horizontally moving and flipping the upper tray, thereby improving the convenience of replacing the electronic components.

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 3. Figure 1 is a three-dimensional schematic diagram of an electronic device according to an embodiment of the present invention. Figure 2 is an exploded schematic diagram of the electronic device of Figure 1. Figure 3 is an exploded schematic diagram of the electronic device of Figure 1 from another perspective.

The electronic device 10 of this embodiment is, for example, a server, and is used to accommodate two motherboards 20 provided with electrical connectors 21, and the electrical connectors 21 are, for example, electrically connected to a power supply 30. The electronic device 10 includes a housing 11, two support racks 12, an upper tray 13, and a lower tray 14. The height of the housing 11 is, for example, 2U. The housing 11 includes a bottom plate 111 and two side plates 112. The two side plates 112 are respectively connected to opposite sides of the bottom plate 111. Each support rack 12 includes two fixed support racks 121 and a movable support rack 122.

Please refer to FIG. 4 as well. FIG. 4 is a schematic cross-sectional view of the electronic device of FIG. 1 . Four fixed support frames 121 are symmetrically fixed to the two side panels 112, respectively, and each side panel 112 is provided with two fixed support frames 121. The distances between the two fixed support frames 121 on each side and the power supply 30 are different. Since the four fixed support frames 121 are symmetrically arranged on the two side panels 112, and the structure of each fixed support frame 121 is the same, one of the fixed support frames 121 will be described below. The fixed support frame 121 has a first guide groove 1211. The first guiding groove 1211 has a transverse guiding portion 12111 and an oblique guiding portion 12112 , and one end of the transverse guiding portion 12111 is connected to one end of the oblique guiding portion 12112 .

The two movable support frames 122 are symmetrically and movably disposed on the two side panels 112. Since the two movable support frames 122 are symmetrically disposed on the two side panels 112 and each movable support frame 122 has the same structure, one of the movable support frames 122 is described below. The movable support frame 122 has a second guide groove 1221, an arc-shaped slide groove 1222 and a first through hole 1223. The first through hole 1223 is located at one end of the arc-shaped slide groove 1222.

One side of the upper tray 13 is hinged to two movable support frames 122, and the other side of the upper tray 13 is movably mounted on four fixed support frames 121, so that the upper tray 13 and the two movable support frames 122 can move relative to the four fixed support frames 121, and the upper tray 13 can rotate relative to the two movable support frames 122. The lower tray 14 is, for example, fixedly mounted on the bottom plate 111. Two motherboards 20 are respectively mounted on the upper tray 13 and the lower tray 14.

Specifically, the upper tray 13 includes four first guide protrusions 131 and two first positioning members 132 on opposite sides. The housing 11 includes four second guide protrusions 113 on opposite sides, and the housing 11 has two positioning holes 114 on opposite sides. The four second guide protrusions 113 are symmetrically disposed on the two side plates 112, and each side plate 112 is provided with two second guide protrusions 113.

Since the four first guide bosses 131 and the two first positioning members 132 are symmetrically arranged on the opposite sides of the upper tray 13, and the four second guide bosses 113 and the two positioning holes 114 are symmetrically arranged on the two side plates 112, and the structures of each first guide boss 131, each first positioning member 132, each second guide boss 113 and each positioning hole 114 are the same, the following description is based on one of the first guide bosses 131, one of the first positioning members 132, two second guide bosses 113 on one side and one of the positioning holes 114.

The first guide protrusion 131 can be movably positioned in the first guide groove 1211, and the two second guide protrusions 113 are located in the second guide groove 1221, and the movable support frame 122 can move relative to the two second guide protrusions 113 to place the upper tray 13 in the use position or the translation position. In addition, the first positioning member 132 can be movably positioned in the arc-shaped slide groove 1222. The positioning hole 114 is located in the side plate 112 and corresponds to the first through hole 1223.

When the first guide protrusion 131 is located at one end of the transverse guide portion 12111 away from the oblique guide portion 12112, and one end of the second guide groove 1221 abuts against one of the two second guide protrusions 113, the upper tray 13 is in the use position. At this time, in the upper tray 13, the power supply 30 is electrically connected to the motherboard 20 through the electrical connector 21.

When the first guide protrusion 131 moves to one end where the horizontal guide portion 12111 and the oblique guide portion 12112 are connected, and the movable support frame 122 moves so that the other end of the second guide groove 1221 abuts against the other of the two second guide protrusions 113, the upper tray 13 is located at the translation position. At this time, in the upper tray 13, the power supply 30 is separated from the motherboard 20.

When the upper tray 13 is at the translation position, the first positioning member 132 is located at one end of the arc-shaped slide groove 1222 away from the first through hole 1223. When the first positioning member 132 moves from the arc-shaped slide groove 1222 to the first through hole 1223, and the first guide protrusion 131 moves from one end of the transverse guide portion 12111 connected to the oblique guide portion 12112 toward one end of the oblique guide portion 12112 away from the transverse guide portion 12111, the upper tray 13 moves from the translation position to the flip position. In other words, the upper tray 13 can be flipped through the movable support frame 122 to expose the lower tray 14.

After the upper tray 13 moves from the translation position to the flip position, the first positioning member 132 passes through the first through hole 1223 and is positioned in the positioning hole 114, so that the upper tray 13 is positioned on the side plate 112. In this way, the upper tray 13 can be stably positioned in the flip position.

In this embodiment, the housing 11 may further include two second positioning members 115. The two second positioning members 115 are respectively disposed on the two side panels 112, and each second positioning member 115 is located between the side panels 112 and the movable support frame 122. Each movable support frame 122 may further include a positioning groove 1224. Since the two second positioning members 115 are symmetrically disposed on the two side panels 112, and the two positioning grooves 1224 are symmetrically disposed on the two movable support frames 122, and each second positioning member 115 and each positioning groove 1224 have the same structure, one of the second positioning members 115 and one of the positioning grooves 1224 will be described below.

The second positioning member 115 includes a positioning protrusion 1151. When the upper tray 13 is at the flip position, the positioning protrusion 1151 of the second positioning member 115 is positioned with the positioning groove 1224. Thus, when the upper tray 13 moves from the translation position to the flip position, the positioning protrusion 1151 and the positioning groove 1224 can prevent the movable support frame 122 from moving relative to the upper tray 13, thereby increasing the stability of the flip of the upper tray 13.

In this embodiment, the housing 11 may further include two stopper bosses 116. The two stopper bosses 116 are respectively located on the two side plates 112. Since the two stopper bosses 116 are symmetrically disposed on the two side plates 112 and each of the stopper bosses 116 has the same structure, one of the stopper bosses 116 is described below. When the upper tray 13 is located at the flip position, the stopper bosses 116 stop the upper tray 13. In this way, the upper tray 13 can be further stably positioned at the flip position.

In this embodiment, the electronic device 10 may further include two locking members 15. Each movable support frame 122 may further have a second through hole 1225, and the housing 11 may further have a locking hole 117. The two locking members 15 are, for example, screws. The two locking holes 117 are, for example, screw holes, and are respectively located on the two side panels 112 and correspond to the second through holes 1225.

Since the two locking members 15 are symmetrically arranged, and the two second through holes 1225 and the two locking holes 117 are symmetrically arranged on the two movable support frames 122 and the two side plates 112, respectively, and each locking member 15, each second through hole 1225 and each locking hole 117 have the same structure, one of the locking members 15, one of the second through holes 1225 and one of the locking holes 117 will be described below.

When the upper tray 13 is in the use position, the locking member 15 passes through the second through hole 1225 and is locked in the locking hole 117, so that the movable support frame 122 is fixed to the side plate 112. In this way, the upper tray 13 can be stably fixed in the use position.

In this embodiment, the upper tray 13 may further include a handle 133. The handle 133 is far away from the two first positioning members 132. The user can use the handle 133 to more conveniently operate the movement of the upper tray 13.

In this embodiment, the advantage of providing the fixed support frame 121 and the movable support frame 122 on the housing 11 is that when the user needs to replace the electronic components of the motherboard 20 disposed on the lower tray 14, there is no need to remove the upper tray 13. The lower tray 14 and the motherboard 20 disposed on the lower tray 14 can be exposed by only horizontally moving and flipping the upper tray 13, thereby improving the convenience of replacing the electronic components.

In this embodiment, by setting two fixed support frames 121 far from the power supply 30 on each side plate 112, the stability of supporting the upper tray 13 can be increased, but the present invention is not limited thereto. In other embodiments, two fixed support frames far from the power supply may not be set on each side plate.

In this embodiment, the number of the supporting racks 12 is two, but not limited thereto. In other embodiments, the number of the supporting racks 12 may also be only one.

In this embodiment, the number of the fixed support frames 121 and the number of the movable support frames 122 of each support frame set 12 are four and two respectively. The four fixed support frames 121 are fixed to the two side panels 112 respectively, and the two movable support frames 122 are movably disposed on the two side panels 112 respectively, so that each side panel 112 is fixed with two fixed support frames 121 and one movable support frame 122, but this is not limited to the present invention. In other embodiments, the number of fixed support frames and movable support frames in each support frame set can also be only one, and the fixed support frame is fixed to one of the two side panels, and the movable support frame can be movably arranged on one of the two side panels and located on the same side as the fixed support frame.

In this embodiment, the lower tray 14 is fixedly disposed on the bottom plate 111, but the present invention is not limited thereto. In other embodiments, the lower tray can also be movably disposed on the bottom plate.

In this embodiment, the number of the second guide protrusions 113 is four, and each side plate 112 is provided with two second guide protrusions 113, but the present invention is not limited thereto. In other embodiments, the number of the second guide protrusions 113 may also be two, and each side plate is provided with one second guide protrusion.

Please refer to Figures 5 to 10. Figure 5 is a three-dimensional schematic diagram of the electronic device of Figure 1 in the use position. Figure 6 is a cross-sectional schematic diagram of the electronic device of Figure 1 in the use position.

Figure 9 is a three-dimensional schematic diagram of the electronic device of Figure 1 in the flip position. Figure 10 is a cross-sectional schematic diagram of the electronic device of Figure 1 in the flip position.

As shown in FIG. 5 and FIG. 6 , taking one side of the housing 11 as an example, the first guide protrusion 131 of the upper tray 13 is located at one end of the transverse guide portion 12111 away from the oblique guide portion 12112, and one end of the second guide groove 1221 abuts against one of the two second guide protrusions 113, so that the upper tray 13 is located in the use position. At this time, in the upper tray 13, the power supply 30 and the motherboard 20 are electrically connected through the electrical connector 21.

As shown in Figures 7 and 8, when the user wants to replace the electronic components of the motherboard 20 disposed on the lower tray 14, first, the lock between the movable support frame 122 and the side plate 112 is released, and the upper tray 13 is moved along the direction A, so that the first guide protrusion 131 of the upper tray 13 moves along the direction A from one end of the transverse guide portion 12111 away from the oblique guide portion 12112 to one end where the transverse guide portion 12111 and the oblique guide portion 12112 are connected, and the movable support frame 122 also moves along the direction A so that the other end of the second guide groove 1221 abuts against the other of the two second guide protrusions 113. At this time, the upper tray 13 moves from the use position to the translation position to separate the power supply 30 from the motherboard 20, and the positioning protrusion 1151 of the second positioning member 115 is positioned with the positioning groove 1224.

As shown in Figures 9 and 10, the user can then move the first positioning member 132 of the upper tray 13 from one end of the arc-shaped slide groove 1222 of the movable support frame 122 away from the first through hole 1223 along direction B to the first through hole 1223, and move the first guide protrusion 131 from one end connecting the transverse guide portion 12111 and the oblique guide portion 12112 along direction C toward one end of the oblique guide portion 12112 away from the transverse guide portion 12111. At this time, the upper tray 13 can be flipped from the translation position along the direction C to the flipped position, and through the positioning of the first positioning member 132 and the positioning hole 114 and the blocking of the blocking protrusion 116, the upper tray 13 can be stably positioned at the flipped position to expose the lower tray 14 and the motherboard 20 disposed on the lower tray 14, thereby improving the convenience of replacing electronic components.

According to the electronic device of the above-mentioned embodiment, since the housing of the electronic device is provided with a fixed support frame and a movable support frame, when the user needs to replace the electronic components of the motherboard arranged on the lower tray, there is no need to remove the upper tray. The lower tray and the motherboard arranged on the lower tray can be exposed by only horizontally moving and flipping the upper tray, thereby improving the convenience of replacing the electronic components.
