Implementation Method

[0019] Before the present invention is described in detail, it should be noted that similar elements are represented by the same numbers in the following description.

[0020] Referring to Figures 1 and 2, an embodiment of the electronic device 100 of the present invention includes a chassis 1, a plurality of first functional modules 2, and a plurality of second functional modules 3. The electronic device 100 is exemplified as a server, but is not limited thereto. The electronic device 100 may also be a storage device. The first functional modules 2 and the second functional modules 3 are disposed within the chassis 1. Each of the first functional modules 2 and each of the second functional modules 3 is exemplified as a PCIe card module, but is not limited thereto. Each of the first functional modules 2 and each of the second functional modules 3 may also be a hard disk module.

[0021] For ease of subsequent explanation, the electronic device 100 is defined as having a front-back direction D1, a left-right direction D2 perpendicular to the front-back direction D1, and a top-bottom direction D3 perpendicular to both the front-back direction D1 and the left-right direction D2. In this embodiment, the front-back direction D1 in Figure 1 is defined as the direction indicated by the arrow (forward) and the opposite direction (backward). The left-right direction D2 in Figure 1 is defined as the direction indicated by the arrow (left) and the opposite direction (right). The top-bottom direction D3 in Figure 1 is defined as the direction indicated by the arrow (up) and the opposite direction (down).

[0022] Referring to Figures 2, 3, and 4, the chassis 1 includes a housing 11 and a rear support 12. The housing 11 has a bottom wall 111, two side walls 112, and a rear frame 113. The side walls 112 are respectively connected to the left and right sides of the bottom wall 111 and are spaced apart along the left-right direction D2. Each side wall 112 has a wall body 114 and a first positioning member 115. The wall body 114 is connected to the bottom wall 111 and is perpendicular to the bottom wall 111. The wall body 114 has a rear end 116. The first positioning member 115 is disposed on the inner wall surface of the wall body 114 and adjacent to the rear end 116. The rear frame 113 is disposed on the top surface of the bottom wall 111 and is located between the rear ends 116 of the side walls 112. The rear frame 113 has a plurality of first fastening components 117 arranged at intervals along the left-right direction D2.

[0023] The rear support 12 is detachably assembled to the housing 11. The rear support 12 includes a flat plate 121, two second positioning members 122, and a plurality of second fastening components 123. The flat plate 121 is used to abut against the rear frame 113 of the housing 11. The second positioning members 122 are respectively disposed on opposite sides of the flat plate 121 and spaced apart along the left-right direction D2. The second positioning members 122 are detachably connected to the first positioning members 115 to position the rear support 12 to the housing 11. The second fastening components 123 are located between the second positioning members 122 and spaced apart along the left-right direction D2. The second fastening components 123 are respectively connected to the first fastening components 117 without tools to fix the rear support 12 to the housing 11. This improves the ease of operation during the assembly and disassembly of the rear support 12 and saves assembly and disassembly time.

[0024] Referring to Figures 3, 4, and 5, in this embodiment, each of the first positioning members 115 of the housing 11 is a cylindrical positioning guide post. Each of the second positioning members 122 of the rear bracket 12 has a side plate 124 connected to one side of the plate 121. The side plate 124 extends downward from the plate 121 and is perpendicular to the plate 121. The side plate 124 forms an inclined positioning groove 125. The positioning groove 125 is slidably connected to and snapped into the corresponding first positioning member 115. By means of the inclined design of the positioning groove 125, when the positioning groove 125 is snapped into the corresponding first positioning member 115, it can prevent the rear bracket 12 from shaking relative to the housing 11 in the front-rear direction D1 and the vertical direction D3, thereby improving the positioning stability of the rear bracket 12.

[0025] Specifically, the side plate 124 has a top edge 126 and a front edge 127 protruding from the front end of the flat plate 121. The positioning groove 125 has an open groove 128 located between the top edge 126 and the front edge 127 and in a square shape, and a snap-fit ​​groove 129 extending backward and downward from the open groove 128 and in an inclined shape. In this embodiment, the open groove 128 is rectangular and its length is parallel to the vertical direction D3. The shape of the open groove 128 is not limited to a rectangular shape; the shape of the open groove 128 can also be square. Each of the first positioning members 115 passes through the open groove 128 of the corresponding positioning groove 125, enters the snap-fit ​​groove 129, and snaps into the snap-fit ​​groove 129. By means of the square-shaped design of the open slot 128 located between the top edge 126 and the front edge 127, the open slot 128 provides a large space for the corresponding first positioning member 115 to pass through, so that the first positioning member 115 can easily and quickly pass through the open slot 128 and extend into the snap-fit ​​slot 129.

[0026] More specifically, the side panel 124 also has a vertical surface 130 connected to the top edge 126 and facing the open slot 128, and a flat surface 131 connected to the front edge 127 and facing the open slot 128. The vertical surface 130 is configured to slide along the first positioning member 115 when in contact with the corresponding first positioning member 115 to guide the position of the snap-fit ​​slot 129 to align with the first positioning member 115. The flat surface 131 is configured to slide along the first positioning member 115 when in contact with the corresponding first positioning member 115 to guide the position of the snap-fit ​​slot 129 to align with the first positioning member 115. Through the design of the vertical surface 130 and the flat surface 131, the positional deviation of the second positioning member 122 during assembly can be absorbed, thereby improving the ease of operation of assembling the positioning groove 125 of the second positioning member 122 with the first positioning member 115.

[0027] Further, the side plate 124 also has an inclined surface 132 located at the top of the latching groove 129, and an arc-shaped latching surface 133 connected to the bottom end of the inclined surface 132 and located at the bottom of the latching groove 129. The inclined surface 132 is configured to slide along the first positioning member 115 when in contact with the corresponding first positioning member 115, thereby guiding the arc-shaped latching surface 133 to move and latch onto the first positioning member 115, thereby allowing the first positioning member 115 to be easily and quickly latched onto the arc-shaped latching surface 133. The arc-shaped latching surface 133 is configured to rotate relative to the first positioning member 115 when in contact with the corresponding first positioning member 115, thereby allowing the second positioning member 122 to rotate smoothly relative to the first positioning member 115.

[0028] Each of the first fastening components 117 has a rear upright wall 118, which forms a retaining hole 119. Each of the second fastening components 123 has a rear upright plate 134 extending downward from the rear end of the plate 121, and a fastener 135 disposed on the rear upright plate 134. The rear upright plate 134 is located behind the rear upright wall 118 of the corresponding first fastening component 117. The fastener 135 is used to fasten to the retaining hole 119 of the corresponding first fastening component 117. In this embodiment, the retaining hole 119 is a screw hole, and the fastener 135 is a hand screw for screwing into the retaining hole 119.

[0029] By using a hand-tightening screw for the fastener 135 of the second fastening component 123 and a screw hole 119 for the retaining hole of the first fastening component 117, the operator can screw the fastener 135 into or out of the retaining hole 119 by hand. This allows the operator to assemble the second fastening component 123 onto or disassemble it from the first fastening component 117 without tools, thus improving ease of assembly and disassembly and saving time. Furthermore, the screwing of the fastener 135 into the retaining hole 119 ensures a stable fastening of the second fastening component 123 to the first fastening component 117. Moreover, the multiple design of both the first fastening component 117 and the second fastening component 123 ensures a stable fixation of the rear bracket 12 to the housing 11. In this embodiment, the number of the first fastening component 117 and the second fastening component 123 is two, but not limited to this, and can be adjusted and changed according to needs.

[0030] Referring to Figures 2, 4, and 5, the flat plate 121 of the rear bracket 12 has a downward-facing pressing surface 136 and an upward-facing upper support surface 137 opposite to the pressing surface 136. The rear bracket 12 also includes a plurality of locking components 138 disposed on the upper support surface 137 and arranged at intervals. Each locking component 138 has a rear frame 139 disposed on the upper support surface 137 and a hand-tight screw 140 disposed on the rear frame 139.

[0031] Referring to Figures 1, 2, and 4, the first functional modules 2 are disposed within the housing 11 and arranged at intervals along the left-right direction D2. The first functional modules 2 are located below the plate 121 of the rear support 12 and are pressed against by the downward pressing surface 136. The second functional modules 3 are disposed within the housing 11 and located above the first functional modules 2, arranged at intervals along the left-right direction D2. The second functional modules 3 are located above the plate 121 of the rear support 12 and are supported by the upper support surface 137. The hand-tightening screw 140 of each locking assembly 138 is used to screw onto the corresponding second functional module 3.

[0032] The assembly method of the electronic device 100 will be described in detail below:

[0033] Referring to Figures 2, 6, and 7, firstly, the first functional modules 2 are assembled inside the housing 11 and connected to the rear frame 113, such that the first functional modules 2 are arranged at intervals along the left-right direction D2. Subsequently, the rear bracket 12 is tilted at an appropriate angle, and then the rear bracket 12 is lowered and placed into the housing 11, so that the open slot 128 of the positioning groove 125 of each second positioning member 122 is positioned behind and aligned with the corresponding first positioning member 115.

[0034] Referring to Figure 8, the rear bracket 12 is then moved forward, so that each of the first positioning members 115 passes through the open slot 128 of the corresponding positioning slide 125 and extends into the snap-fit ​​slot 129. During the forward movement of the rear bracket 12, when the height of the rear bracket 12 in the vertical direction D3 is low enough that the vertical surface 130 contacts the corresponding first positioning member 115, the vertical surface 130 will slide upward along the first positioning member 115 to guide the position of the snap-fit ​​slot 129 so that it is aligned with the first positioning member 115, so that the first positioning member 115 can smoothly extend into the snap-fit ​​slot 129. When the rear bracket 12 is at a higher height in the vertical direction D3, causing the plane 131 to contact the corresponding first positioning member 115, the plane 131 will slide downward along the first positioning member 115 to guide the position of the latching groove 129 to align with the first positioning member 115, allowing the first positioning member 115 to smoothly extend into the latching groove 129. This absorbs the positional deviation of the rear bracket 12 in the vertical direction D3, allowing the positioning groove 125 of each second positioning member 122 to easily and quickly allow the corresponding first positioning member 115 to extend into the latching groove 129.

[0035] Referring to Figures 8 and 9, when the inclined surface 132 of each of the second positioning members 122 contacts the corresponding first positioning member 115, the inclined surface 132 will slide upward along the first positioning member 115 to guide the arc-shaped latching surface 133 to move upward toward the first positioning member 115. When the arc-shaped latching surface 133 of each of the second positioning members 122 contacts the corresponding first positioning member 115 and is blocked by it, the rear bracket 12 can no longer move forward.

[0036] Referring to Figures 6, 9, and 10, the rear bracket 12 is then rotated along a first rotation direction R1, causing the arc-shaped latching surface 133 of each of the second positioning members 122 to rotate around the corresponding first positioning member 115 as an axis. When the downward pressing surface 136 of the plate 121 of the rear bracket 12 is blocked by the top of the rear frame 113 and the top of the first functional modules 2, the rear bracket 12 can no longer rotate and is positioned on the housing 11. At this time, each of the first positioning members 115 latches onto the latching groove 129 and the arc-shaped latching surface 133 of the corresponding second positioning member 122. The downward pressing surface 136 of the plate 121 presses against the first functional modules 2. Each of the second fastening components 123 has a rear upright plate 134 located behind the rear upright wall 118 of the corresponding first fastening component 117, and each of the second fastening components 123 has a fastener 135 aligned with the retaining hole 119 of the corresponding first fastening component 117. The engagement of the arc-shaped snap-fit ​​surface 133 with the first positioning member 115 prevents the rear bracket 12 from wobbling relative to the housing 11 in the front-rear direction D1. The engagement of the inclined surface 132 and the arc-shaped snap-fit ​​surface 133 with the first positioning member 115 prevents the rear bracket 12 from wobbling relative to the housing 11 in the vertical direction D3. This allows the rear bracket 12 to be stably positioned on the housing 11.

[0037] Referring to Figure 11, the fastener 135 of each of the second fastening components 123 is then rotated forward so that it is screwed into the retaining hole 119 of the corresponding first fastening component 117. When the fastener 135 is screwed into the retaining hole 119, the rear bracket 12 is fixed to the housing 11.

[0038] Referring to Figure 12, finally, the second functional modules 3 are assembled into the housing 11 and abut against the upper support surface 137 of the plate 121 of the rear bracket 12, so that the first functional modules 2 are arranged at intervals along the left-right direction D2 and supported by the upper support surface 137. The hand screw 140 of each locking assembly 138 is rotated clockwise and screwed onto the corresponding second functional module 3 to lock the rear frame 139 to the corresponding second functional module 3. At this point, the assembly of the electronic device 100 is complete.

[0039] By having the flat plate 121 of the rear bracket 12 press against the first functional modules 2 via the lower pressing surface 136 and support the second functional modules 3 via the upper supporting surface 137, the rear bracket 12 can simultaneously press and fix the first functional modules 2 and support the second functional modules 3. Furthermore, by having the hand-tight screw 140 of each locking component 138 screwed onto the corresponding second functional module 3, the operator can fix the rear bracket 12 to the second functional module 3 without using tools. This allows the first functional modules 2 and the second functional modules 3 to be easily and quickly assembled into the rear window structure formed by the rear bracket 12 and the rear frame 113. Moreover, the connection between the rear bracket 12 and the housing 11, the first functional modules 2, and the second functional modules 3 strengthens the structural strength of the rear window structure.

[0040] The following will provide a detailed explanation of the disassembly method for the electronic device 100:

[0041] Referring to Figures 11 and 12, the hand screw 140 of each locking component 138 is rotated in the opposite direction to separate it from the corresponding second functional module 3. At this time, the second functional module 3 can be moved away from the housing 11 and the rear bracket 12. Subsequently, the fastener 135 of each second fastening component 123 is rotated in the opposite direction to unscrew it from the retaining hole 119 of the corresponding first fastening component 117 and separate it from the retaining hole 119, thereby releasing the fastening state of the fastener 135.

[0042] Referring to Figures 6, 7, and 9, the rear bracket 12 is rotated by an appropriate angle along a second rotation direction R2 opposite to the first rotation direction R1 (as shown in Figure 10), so that the arc-shaped latching surface 133 of each of the second positioning members 122 rotates around the corresponding first positioning member 115 as an axis. Then, the rear bracket 12 is moved backward, causing the latching groove portion 129 and the open groove portion 128 of each positioning slide groove 125 to sequentially move away from the corresponding first positioning member 115. When the open groove portion 128 of each positioning slide groove 125 moves away from the corresponding first positioning member 115, the rear bracket 12 can be moved upward and detached from the housing 11. Finally, the first functional modules 2 are detached from the housing 11, thus completing the disassembly of the electronic device 100.

[0043] It should be noted that the electronic device 100 of this embodiment may also have the following different implementations depending on the requirements:

[0044] In one embodiment, the number of the first fastening component 117 and the number of the second fastening component 123 are each one.

[0045] Another embodiment: the retaining hole 119 of each of the first fastening components 117 is a snap-fit ​​hole, and the fastener 135 of each of the second fastening components 123 is a rotating snap-fit ​​member pivotally connected to the rear upright plate 134. The fastener 135 is snapped into the retaining hole 119 by snap-fit ​​to fix the rear bracket 12 to the housing 11.

[0046] In summary, the electronic device 100 of this embodiment uses the second positioning members 122 to be detachably connected to the first positioning members 115 to position the rear bracket 12 on the housing 11, and the second fastening components 123 to be connected to the first fastening components 117 without tools to fix the rear bracket 12 on the housing 11. In this way, the ease of operation of the rear bracket 12 can be improved and the disassembly and assembly time can be saved, so the purpose of the present invention can be achieved.

[0047] However, the above description is only an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the patent specification shall still fall within the scope of the patent of the present invention.
