[0035] Please see Figures 1 to 4 In this embodiment, the electronic device 30 is adapted to house the circuit board 10, which may be a small circuit board, an expansion card, or other expansion structure, but is not limited thereto. The electronic device 30 includes a motherboard 40 and a circuit board quick-release mounting bracket 100. The circuit board quick-release mounting bracket 100 is used to secure the circuit board 10.

[0036] The circuit board quick-release mounting bracket 100 is partially disposed on the motherboard 40 and partially extends beyond the motherboard 40. In this embodiment, the circuit board 10 disposed on the circuit board quick-release mounting bracket 100 is located outside the motherboard 40. This design allows for more space on the circuit board 10, providing greater configuration flexibility for the circuit board 10. In other embodiments, the circuit board 10 may also be partially located on the motherboard 40 and partially located outside the motherboard 40, without limitation by the drawings.

[0037] In addition, in this embodiment, the circuit board quick-release fixing bracket 100 is fixed to the circuit board 10 by locking, but this is not a limitation. In other embodiments, the circuit board quick-release fixing bracket 100 can also be fixed to the circuit board 10 by welding, snap-fitting or riveting.

[0038] like Figure 4As shown, in this embodiment, the circuit board quick-release fixing bracket 100 includes a bracket body 110, a plurality of limiting members 120, and an elastic arm 130. The bracket body 110 includes a bottom surface 111 and at least one side surface 114 connected to each other. The bottom surface 111 and the at least one side surface 114 form a receiving groove 115 to accommodate the circuit board 10. In this embodiment, the number of side surfaces 114 is, for example, four, but is not limited thereto.

[0039] Furthermore, in this embodiment, the bottom surface 111 has a first region 112 and a second region 113 connected together, the first region 112 being, for example, Figure 4 The area located on the right side within the receiving slot 115, the second area 113 is, for example, Figure 4 The region is located on the left side within the receiving slot 115. The bracket body 110 includes a plurality of support posts 140 protruding from the first region 112, which support the circuit board 10 when it is located in the first region 112.

[0040] These limiting members 120 are disposed on at least one side 114 to restrict the circuit board 10 from disengaging from the receiving groove 115 along the first direction D1. In this embodiment, the limiting members 120 are disposed on, for example, three of the sides 114, particularly at a position next to the second region 113.

[0041] The elastic arm 130 is flexibly disposed on the bottom surface 111. Specifically, in this embodiment, one end of the elastic arm 130 is located in the first region 112, and the other end of the elastic arm 130 is located in the second region 113. The elastic arm 130 includes an engaging portion 132, which is located in the second region 113. The circuit board 10 includes a hole 20, and when the circuit board 10 moves from the first region 112 to the second region 113, the engaging portion 132 is adapted to extend into the hole 20. Therefore, the engaging portion 132 can restrict the circuit board 10 from disengaging from the receiving groove 115 along a second direction D2 perpendicular to the first direction D1.

[0042] Depend on Figure 3 As can be seen, in this embodiment, the elastic arm 130 includes a pressing portion 134 located in the first region 112, and the pressing portion 134 includes a plurality of protruding ribs 136. The pressing portion 134 is used by the user to press, so that the elastic arm 130 moves downward, thereby releasing the restriction of the engaging portion 132 on the circuit board 10. The design of the protruding ribs 136 can improve the visual effect of the pressing portion 134 and achieve the effect of anti-slip.

[0043] Of course, the form of the circuit board quick-release fixing bracket 100 is not limited to this. Another embodiment of the circuit board quick-release fixing bracket 100a is described below.

[0044] Figure 5 This is a schematic diagram of a quick-release mounting bracket for a circuit board according to another embodiment of this case. Figure 6The circuit board is installed Figure 5 A schematic diagram of a quick-release mounting bracket for a circuit board.

[0045] Please see Figure 5 and Figure 6 In this embodiment, the circuit board quick-release fixing bracket 100a can be set on the chassis (not shown) or partially set on the motherboard 40, but the setting position of the circuit board quick-release fixing bracket 100a is not limited thereto.

[0046] The circuit board quick-release fixing bracket 100a includes a bracket body 110, a plurality of limiting members 120 and an elastic arm 130. The bracket body 110 includes a bottom surface 111 and at least one side surface 114 connected to each other, and the bottom surface 111 and at least one side surface 114 form a receiving groove 115 to accommodate the circuit board 10.

[0047] These limiting members 120 are disposed on at least one side 114 to restrict the circuit board 10 from disengaging from the receiving groove 115 along a first direction D1. The elastic arm 130 is flexibly disposed on the bottom surface 111 and includes an engaging portion 132 adapted to restrict the circuit board 10 from disengaging from the receiving groove 115 along a second direction D2 perpendicular to the first direction D1.

[0048] Specifically, there are at least a plurality of side surfaces 114, wherein two side surfaces 114 are located on opposite sides, and the limiting members 120 are provided on at least one side surface 114, and the engaging part 132 is located on the other side surface 114, and the engaging part 132 is coplanar with the other side surface 114 to be adapted to abut against the side edge of the circuit board 10.

[0049] Furthermore, in this embodiment, the engaging portion 132 is connected to the lever portion 138, and the lever portion 138 protrudes from the side 114 to facilitate the user's levering and movement of the engaging portion 132 to facilitate the insertion or removal of the circuit board 10. Therefore, the circuit board quick-release fixing bracket 100a can fix the circuit board 10 without tools, and only the elastic arm 130 needs to be moved when installing or removing the circuit board 10, which is quite convenient to use.

[0050] In summary, the quick-release circuit board mounting bracket of this invention has receiving grooves formed on its bottom and sides to accommodate the circuit board. These limiting members are located on the sides to restrict the circuit board from disengaging from the receiving groove in a first direction. A flexible arm is flexibly disposed on the bottom surface and includes a locking portion adapted to restrict the circuit board from disengaging from the receiving groove in a second direction perpendicular to the first direction. Therefore, the quick-release circuit board mounting bracket can secure the circuit board without tools; installation or removal of the circuit board only requires moving the flexible arm, making it quite convenient to use. Furthermore, because the quick-release circuit board mounting bracket of this invention is partially disposed on the circuit board and partially extends beyond it, it frees up more space on the circuit board, providing greater flexibility in circuit board configuration.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this case, and not to limit them; although this case has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features; and these 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 case.
