[0077] Figure 1 FIG. 1 is a three-dimensional diagram of a server device 10 according to an embodiment of the present invention. Figure 2 for Figure 1 A partial exploded view of the server device 10. Figure 1 and Figure 2 As shown, in this embodiment, the server device 10 includes a chassis 100 and a circuit board module 200. The chassis 100 includes a box body 110, a cover body 130 and a circuit board module 200.

The first cover 131 and the second cover 132 cover the box 110 and the internal space 120 in sequence.

[0078] Figure 3 for Figure 2 An exploded view of the circuit board module 200 is shown. Figure 4 for Figure 3 A schematic diagram of another perspective of the connecting rod 410. Figure 2 and Figure 3 As shown, in this embodiment, the circuit board module 200 includes an extraction bracket 300 and a circuit board 210, and the circuit board 210 is placed on the extraction bracket 300. The extraction bracket 300 includes a bottom plate 310, a U-shaped handle 400 and two wing plates 320. The top surface 311 of the bottom plate 310 of the extraction bracket 300 can be used for the circuit board 210 to be placed flat thereon. These wing plates 320 are relatively arranged on the top surface 311 of the bottom plate 310. The U-shaped handle 400 includes a connecting rod 410 and two lugs 420. The connecting rod 410 is respectively connected to one end of these lugs 420, and these lugs 420 extend downward (such as the Z axis) from the connecting rod 410, and the sides of these lugs 420 facing away from the connecting rod 410 are respectively fixed to these wing plates 320.

[0079] For example, one side of the U-shaped handle 400 (refer to the top 411) includes a plurality of attached stickers S, each of which has an indicator symbol different from one another. Each wing 320 has a bottom side 321, a straight side 322, and an oblique side 323, the bottom side 321 is connected to the bottom plate 310, and the straight side 322 is connected to one of the lugs 420. The oblique side 323 is arranged relative to the straight side 322 and gradually extends obliquely toward the bottom plate 310. In addition, the extraction bracket 300 further includes two folding wings 330. These folding wings 330 are respectively convexly arranged on two opposite sides of the bottom plate 310, and each folding wing 330 is respectively connected to the bottom plate 310 and the straight side 322 of one of the wing plates 320.

[0080] like Figure 4 As shown, one side (refer to the bottom 412 ) of the U-shaped handle 400 includes a plurality of grid-shaped grooves 403 , which are arranged in an array, and the long axis direction of each grid-shaped groove 403 is parallel to the long axis direction (eg, Y-axis) of the connecting rod 410 .

[0081] Figure 5 3 is a cross-sectional view along line segment AA, which is a cross-sectional view of the connecting rod 410. Figure 5 As shown, the cross section of the connecting rod 410 includes a top 411, a bottom 412, a flat side 413 and a gripping flange 414. The bottom 412 is opposite to the top 411 and faces the bottom plate 310 ( Figure 3The flat side surface 413 is adjacent to the bottom 412 and the top 411 and is connected to one of the lugs 420. The gripping flange 414 is opposite to the flat side surface 413, adjacent to the bottom 412 and the top 411, and protrudes in a direction away from the flat side surface 413.

[0082] More specifically, the gripping flange 414 includes a first turning arc surface 414A, a second turning arc surface 414B, and an inclined surface 414C, wherein the first turning arc surface 414A is connected to the top 411, the second turning arc surface 414B is connected to the bottom 412, and the inclined surface 414C connects the first turning arc surface 414A and the second turning arc surface 414B, and the arc θ1 of the first turning arc surface 414A is greater than the arc θ2 of the second turning arc surface 414B. The arc θ1 is, for example, 45°, and the arc θ2 is, for example, 30°.

[0083] FIG. 6A to FIG. 6C The following are the continuous operation diagrams of loading the extraction bracket 300 into the chassis 100. Fig. 6A As shown, the case 100 inevitably has a transverse protrusion structure 140, which is located in the internal space 120 and extends from the inner wall 114 of the case 110. For example, the transverse protrusion structure 140 may be a structure formed integrally with the case 110, or an input / output (I / O) module in the case 110, but the present invention is not limited thereto. In this way, the assembler cannot vertically place the extraction bracket 300 in the case 110, and must rotate the extraction bracket 300 to avoid the transverse protrusion structure 140 in the case, so as to effectively use the space.

[0084] Therefore, when the assembler intends to put the extraction bracket 300 into the chassis 100, as shown in FIG. Fig. 6A and Figure 6B As shown in FIG. 1 , the assembler first grasps the connecting rod 410 of the U-shaped handle 400 and moves the extraction bracket 300 to the top of the case 100; then, the assembler rotates the extraction bracket 300 in a clockwise direction C1 through the connecting rod 410, and at this time, the bottom plate 310 of the entire extraction bracket 300 and the bottom surface 111 of the case 110 are not parallel to each other; then, as shown in FIG. Figure 6B and Figure 6C As shown, when the extraction bracket 300 approaches the transverse protrusion structure 140 in the chassis 100, the assembler rotates the extraction bracket 300 in the counterclockwise direction C2 through the connecting rod 410, so that part of the extraction bracket 300 can be rotated between the transverse protrusion structure 140 and the bottom surface 111 of the box body 110 ( Figure 6C ) for subsequent locking assembly.

[0085] It is important to understand that if Figure 5 and Figure 6BAs shown, since the contour of the gripping flange 414 is quite consistent with the bending degree of the assembler's finger F when gripping, that is, the assembler's finger F can rest comfortably on the first turning arc surface 414A, the second turning arc surface 414B and the inclined surface 414C, thereby smoothly improving the assembler's control over the movement of the extraction bracket 300.

[0086] In addition, when the assembler grasps the connecting rod 410 of the U-shaped handle 400 and rotates the extraction bracket 300, since the lugs 420 of the U-shaped handle 400 are respectively fixedly connected to the wing plates 320 of the extraction bracket 300, the structural strength can be improved, thereby reducing the rotation torque of the extraction bracket 300 by the assembler and facilitating the grasping of the extraction bracket 300.

[0087] like Figure 3 As shown, the circuit board module 200 further includes a fan assembly 220. The fan assembly 220 includes a fan frame 221 and a plurality of fan units 230. The fan frame 221 is located on the circuit board 210 and faces the connecting rod 410. The fan units 230 are stacked in the fan frame 221 in sequence along a vertical direction (such as the Z axis) and are electrically connected to the circuit board 210.

[0088] More specifically, in this embodiment, if Figure 3 As shown in FIG. 6 , the circuit board 210 includes a board body 211, a plurality of connectors 212 and circuit components (not shown). The board body 211 is placed on the bottom plate 310 of the extraction bracket 300. These connectors 212 are arranged in sequence on the board body 211 and electrically connect the board body 211 and the above-mentioned circuit components (not shown). When the fan assembly 220 is assembled to the circuit board 210, the fan frame 221 covers these connectors 212, so that the fan units 230 in the fan frame 221 are electrically connected to the corresponding connectors 212 respectively. However, the utility model is not limited to the circuit board module 200 having the fan assembly 220.

[0089] Furthermore, Figure 7 for Figure 2 A front view of the circuit board module 200 is shown. Figure 3 and Figure 7 As shown, the fan frame 221 has a plurality of air outlets 222 on one side facing the connecting rod 410, and these air outlets 222 are aligned with the fan units 230 one by one. The orthographic projection P of the connecting rod 410 along the X-axis direction to the fan frame 221 is exactly located at two of the air outlets (such as 222A, 222B, and 222C) arranged along the vertical direction (such as the Z-axis direction). Figure 7 ), so that the connecting rod 410 will not hinder the air volume pushed by the fan unit 230 at the corresponding air outlet 222, thereby not affecting the heat dissipation performance of the fan unit 230.

[0090] Figure 8FIG. 3 is a perspective view of an extraction bracket 301 according to an embodiment of the present invention. Figure 8 As described above, the extraction bracket 301 of this embodiment is substantially the same as the extraction bracket 300 described above, and the difference is that the connecting rod 410A of the extraction bracket 301 described above has a convex surface 415. More specifically, the convex surface 415 is at least located at the gripping flange 414 of the connecting rod 410A. In this way, a better gripping feeling can be provided to the assembler, thereby facilitating the assembler to move and rotate the extraction bracket 300.

[0091] However, the present invention is not limited thereto, and in other embodiments, the gripping flange 414 of the connecting rod 410A may also have a textured surface; or, these convex surfaces 415 (or textured surfaces) may also be expressed as the above-mentioned indicator symbols, and the above-mentioned attached stickers may be omitted.

[0092] In the above embodiment, the chassis 100 is a rack-type server chassis (Rack) for accommodating the above-mentioned related electronic devices. The height of the chassis 100 is measured in U units (1U equals 1.75 inches or 44.45 mm). The chassis 100 is, for example but not limited to, a 7U standard server chassis.

[0093] Thus, through the above structure, the server device, circuit board module and extraction bracket of the utility model help the assembler to grasp the extraction bracket, so that the assembler can put it into the chassis and rotate it more easily and labor-savingly, thereby reducing the risk of damaging the internal components of the server and causing occupational injuries.

[0094] Finally, the above disclosed embodiments are not intended to limit the present invention. Anyone skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all of them can be protected by the present invention. Therefore, the scope of protection of the present invention shall be determined by the definition of the attached claims.
