Technical Field

[0001] This utility model relates to a fixed bracket and an electronic device, and more particularly to an expansion card quick-release fixed bracket and an electronic device. Background Technology

[0002] Currently, expansion cards mounted on circuit boards or motherboards are secured to brackets with screws at their ends, and are fixed to the circuit board or motherboard together with the brackets. However, installing or removing expansion cards requires tools, which is inconvenient. How to install or remove expansion cards more conveniently and quickly is a research direction in this field. Furthermore, because expansion cards and brackets occupy a significant amount of space on the circuit board or motherboard, they limit the flexibility of space configuration on the board. Utility Model Content

[0003] This invention discloses a quick-release expansion card holder suitable for securing expansion cards, the expansion cards having an end. The quick-release expansion card holder includes a load-bearing portion, a support member, and a flexible arm. The load-bearing portion is suitable for supporting the expansion card. The support member extends upward from the load-bearing portion to form an inverted U-shaped structure. The flexible arm is flexibly disposed within the movable space surrounded by the inverted U-shaped structure and includes opposing fixed and movable ends. The fixed end is connected to the inverted U-shaped structure and located above the movable end, while the movable end is close to the opening of the inverted U-shaped structure and includes a connected inclined surface and a locking portion. When the end of the expansion card is subjected to downward force, the end pushes the inclined surface, causing the flexible arm to move backward until the end passes downward through the inclined surface. Then, the flexible arm returns to its original position, thereby causing the locking portion to abut against the end.

[0004] According to one embodiment of the present invention, the elastic arm has opposing inner and outer surfaces, the outer surface being oriented toward the movable space when the elastic arm moves backward, the engaging portion being connected to the outer surface, and the inclined surface being located on the inner surface.

[0005] According to one embodiment of the present invention, the included angle between the engaging portion and the connected outer surface is between 80 degrees and 100 degrees.

[0006] According to one embodiment of the present invention, the bearing portion includes a plurality of support ribs located below the elastic arm. When the expansion card is limited by the engaging portion, the expansion card rests against the plurality of support ribs.

[0007] According to one embodiment of the present invention, the supporting part includes two guide surfaces, which face each other and are spaced apart. When the end of the expansion card moves downward, the two opposite long side edges of the expansion card move downward along the two guide surfaces.

[0008] An electronic device of this invention is suitable for mounting an expansion card, the expansion card having an end, including a circuit board and an expansion card quick-release mounting bracket. The circuit board includes a connector, to which the expansion card is adapted to be inserted. The expansion card quick-release mounting bracket is partially disposed on the circuit board and partially extends beyond the circuit board. The expansion card quick-release mounting bracket includes a carrier portion, a support member, and a resilient arm. The carrier portion is adapted to carry the expansion card. The support member extends upward from the carrier portion to form an inverted U-shaped structure. The resilient arm is flexibly disposed within the movable space surrounded by the inverted U-shaped structure and includes opposing fixed and movable ends. The fixed end is connected to the inverted U-shaped structure and located above the movable end, the movable end is close to the opening of the inverted U-shaped structure, and the movable end includes a connected inclined surface and a locking portion. When the end of the expansion card is subjected to downward force, the end pushes the inclined surface, causing the resilient arm to move backward until the end passes downward through the inclined surface, at which point the resilient arm returns to its original position, thereby causing the locking portion to abut against the end.

[0009] According to one embodiment of the present invention, the elastic arm has opposing inner and outer surfaces, the outer surface being oriented toward the movable space when the elastic arm moves backward, the engaging portion being connected to the outer surface, and the inclined surface being located on the inner surface.

[0010] According to one embodiment of the present invention, the included angle between the engaging portion and the connected outer surface is between 80 degrees and 100 degrees.

[0011] According to one embodiment of the present invention, the bearing portion includes a plurality of support ribs located below the elastic arm. When the expansion card is limited by the engaging portion, the expansion card rests against the plurality of support ribs.

[0012] According to one embodiment of the present invention, the supporting part includes two guide surfaces, which face each other and are spaced apart. When the end of the expansion card moves downward, the two opposite long side edges of the expansion card move downward along the two guide surfaces.

[0013] Based on the above, the support member of the expansion card quick-release mounting bracket in this case extends upward from the bearing portion to form an inverted U-shaped structure. A flexible arm is flexibly disposed within the movable space surrounded by the inverted U-shaped structure. The fixed end of the flexible arm is connected to the inverted U-shaped structure and located above the movable end, with the movable end close to the opening of the inverted U-shaped structure. When the end of the expansion card is subjected to downward force, it pushes the inclined surface of the movable end, causing the flexible arm to move backward until it passes the inclined surface downward. The flexible arm then returns to its original position, causing the engaging portion of the movable end to abut against the end. Therefore, the expansion card quick-release mounting bracket can secure the expansion card without tools, and removal only requires moving the flexible arm backward, making installation and removal of the expansion card quite convenient. Furthermore, because the expansion card quick-release mounting bracket of this electronic device is partially disposed on the circuit board and partially extends beyond the circuit board, more space on the circuit board is freed up, providing greater flexibility in circuit board configuration.

Figure 2 yes Figure 1 A schematic diagram showing the expansion card after it has been viewed through. Figure 3 yes Figure 2 A schematic diagram from another perspective.

[0041] Please see Figures 1 to 5 In this embodiment, the electronic device 20 is adapted to accommodate an expansion card 10. The expansion card 10 is, for example, an M.2 interface solid-state drive; in other embodiments, the expansion card 10 may also be a network card, and the type of expansion card 10 is not limited thereto. The expansion card 10 has a terminal 12.

[0042] Electronic device 20 includes circuit board 30 and expansion card quick-release mounting bracket 100. In this embodiment, circuit board 30 is, for example, a motherboard, but is not limited thereto. Expansion card quick-release mounting bracket 100 is used to secure expansion card 10.

[0043] Circuit board 30 includes connector 32 ( Figure 4 The connector 32 is, for example, an M.2 interface connector 32, but the type of connector 32 is not limited thereto. The expansion card 10 is adapted to be inserted into the connector 32, with the end 12 of the expansion card 10 away from the connector 32.

[0044] Depend on Figure 1As can be seen, in this embodiment, the expansion card quick-release mounting bracket 100 is partially disposed on the circuit board 30 and partially extends beyond the circuit board 30. Therefore, the expansion card 10 disposed on the expansion card quick-release mounting bracket 100 will also be partially located on the circuit board 30 and partially located outside the circuit board 30. This design allows for more space on the circuit board 30, providing greater configuration flexibility for the circuit board 30.

[0045] In addition, in this embodiment, the expansion card quick-release mounting bracket 100 is fixed to the circuit board 30 by means of locking, but this is not a limitation. In other embodiments, the expansion card quick-release mounting bracket 100 may also be fixed to the circuit board 30 by means of welding, snap-fitting or riveting.

[0046] The following is a detailed introduction to the expansion card quick-release mounting bracket 100.

[0047] like Figures 2 to 5 As shown, in this embodiment, the expansion card quick-release mounting bracket 100 includes a bearing portion 110, a support member 120, and an elastic arm 130. The bearing portion 110 is adapted to bear the expansion card 10 in position near the end 12. In this embodiment, the bearing portion 110 includes a plurality of support ribs 112, which are located below the elastic arm 130. When the expansion card 10 is installed into the expansion card quick-release mounting bracket 100 and is limited by the engaging portion 136, the expansion card 10 rests against these support ribs 112.

[0048] In addition, the carrier 110 includes two guide surfaces 114 facing each other and spaced apart. When the end 12 of the expansion card 10 moves downward, the two opposite long side edges of the expansion card 10 move downward along the two guide surfaces 114 so that the end 12 of the expansion card 10 can remain stable during the downward movement.

[0049] Furthermore, the support member 120 extends upward from the bearing portion 110 to form an inverted U-shaped structure 122. An elastic arm 130 is flexibly disposed within the movable space 124 surrounded by the inverted U-shaped structure 122. The elastic arm 130 includes a fixed end 133 and a movable end 134. The fixed end 133 is connected to the inverted U-shaped structure 122 and located above the movable end 134, which is close to the opening of the inverted U-shaped structure 122. The movable end 134 includes a connecting inclined surface 135 and a locking portion 136.

[0050] In this embodiment, when the end 12 of the expansion card 10 is moved downward under force, the end 12 pushes the inclined surface 135, causing the elastic arm 130 to move backward until the end 12 passes downward through the inclined surface 135. Then, the elastic arm 130 returns to its original position, causing the engaging portion 136 to abut against the end 12. Therefore, the expansion card quick-release fixing bracket 100 can fix the expansion card 10 without tools. When removing it, simply move the elastic arm 130 backward, making the installation or removal of the expansion card 10 quite convenient.

[0051] It is worth mentioning that in this embodiment, the latching part 136 is a reverse hook. This design allows the electronic device 20 to better secure the expansion card 10 when it is impacted, thus preventing the expansion card 10 from easily coming off the hook.

[0052] Specifically, the elastic arm 130 has an inner surface 131 and an outer surface 132, with the outer surface 132 facing the movement space 124 when the elastic arm 130 moves backward. A locking portion 136 is connected to the outer surface 132, and a slope 135 is located on the inner surface 131. Figure 5 It can be seen that the angle θ between the engaging part 136 and the connected outer surface 132 is between 80 degrees and 100 degrees, for example, 90 degrees, but is not limited thereto.

[0053] Therefore, when the expansion card 10 is installed into the expansion card quick-release mounting bracket 100 and is limited by the engaging part 136, the reverse hook-shaped engaging part 136 can abut against the end 12 of the expansion card 10, thereby reducing the probability of the elastic arm 130 moving backward due to vibration or impact.

[0054] In summary, the support member of the expansion card quick-release mounting bracket in this case extends upward from the bearing portion to form an inverted U-shaped structure. The elastic arm is flexibly disposed within the movable space surrounded by the inverted U-shaped structure. The fixed end of the elastic arm is connected to the inverted U-shaped structure and located above the movable end, with the movable end close to the opening of the inverted U-shaped structure. When the end of the expansion card is subjected to downward force, it pushes the inclined surface of the movable end, causing the elastic arm to move backward until it passes the inclined surface downward. The elastic arm then returns to its original position, causing the engaging portion of the movable end to abut against the end. Therefore, the expansion card quick-release mounting bracket can secure the expansion card without tools, and removal only requires moving the elastic arm backward, making installation and removal of the expansion card quite convenient. Furthermore, because the expansion card quick-release mounting bracket of this electronic device is partially disposed on the circuit board and partially extends beyond the circuit board, it frees up more space on the circuit board, providing greater flexibility in circuit board configuration.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
