[0062] The following will disclose multiple embodiments of the utility model with the accompanying drawings. For the sake of clarity, many practical details will be described together in the following description. However, those skilled in the art should understand that in some embodiments of the utility model, these practical details are not necessary and should not be used to limit the utility model. In addition, in order to simplify the drawings, some commonly used structures and components will be illustrated in a simple schematic manner in the drawings. In addition, for the convenience of readers, the sizes of the components in the drawings are not drawn according to the actual scale.

[0063] Figure 1 It is a three-dimensional diagram of a fan front frame 10 according to an embodiment of the present invention. Figure 2 for Figure 1 FIG. 1 is an exploded view of components of the fan front frame 10 . Figure 3 for Figure 1 The top view of the fan front frame 10 and the enlarged view of the part M thereof. Figures 1 to 3 As shown, in this embodiment, the fan front frame 10 includes a frame body 100 and a plurality of (for example, 2) first reinforcing sheets 200. The frame body 100 includes a bottom plate 110, two long side portions 120 and two short side portions 130. The bottom plate 110 is substantially rectangular, the long side portions 120 are respectively located at two opposite sides of the bottom plate 110, and the short side portions 130 are respectively located at the other two opposite sides of the bottom plate 110. The bottom plate 110, the long side portions 120 and the short side portions 130 are integrally formed with each other and jointly define an inner groove space 170. The first reinforcing sheets 200 are respectively embedded (or buried) inside the long side portions 120. In other words, all surfaces of each first reinforcing sheet 200 directly contact the long side portions 120 therein. The long axis direction (Y axis) of each first reinforcing sheet 200 is parallel to the long axis direction (Y axis) of the long side portion 120.

[0064] In this embodiment, more specifically, each first reinforcing sheet 200 includes a rigid sheet 210. The rigid sheet 210 is completely buried in the long side portion 120, and the long axis direction (such as the Y axis) of the rigid sheet 210 is parallel to the long axis direction (such as the Y axis) of the long side portion 120. The rigid sheet 210 has a first main surface 211, a second main surface 212, and at least one side surface 213. The first main surface 211 faces the inner groove space 170, the second main surface 212 faces away from the inner groove space 170, and the side surface 213 is located between the first main surface 211 and the second main surface 212. The directions (such as the X axis) facing the first main surface 211 and the second main surface 212 are orthogonal to the direction (such as the Z axis) facing the side surface 213, and the area of ​​the first main surface 211 (or the second main surface 212) is larger than the area of ​​the side surface 213.

[0065] Thus, since the configuration posture of the first reinforcing sheet 200 is similar to the configuration posture of the long side portion 120, the first reinforcing sheet 200 embedded in the long side portion 120 can more effectively provide the structural strength of the frame body 100 of the fan front frame 10, thereby reducing the risk of deformation of the fan front frame 10.

[0066] In this embodiment, but not limited thereto, the first reinforcing sheet 200 further includes a plurality of (e.g., 3) raised portions 220 and a plurality of (e.g., 2) notches 240. Each raised portion 220 protrudes from a side (i.e., the second main surface 212) of the rigid sheet 210 that faces away from the inner groove space 170, so that a recessed portion 230 is formed in the area where the rigid sheet 210 faces the inner groove space 170 and is aligned with the raised portion 220. These notches 240 are respectively located on the raised portions 220 and connected to the recessed portions 230 to accommodate a portion of the long side portion 120, so as to improve the holding strength of the first reinforcing sheet 200 to the frame body 100.

[0067] In addition, the fan front frame 10 further includes a plurality of (e.g., 2) first locking elements 400. Each first locking element 400 includes a first stud 410 and a first screw hole 420. The first screw hole 420 passes through the first stud 410, and the axial direction (e.g., Y axis) of the first screw hole 420 is parallel to the long axis direction (e.g., Y axis) of the first reinforcing sheet 200. The first stud 410 is embedded (or buried) inside one of the short side portions 130. In other words, at least one surface (e.g., circumferential surface) of each first locking element 400 directly contacts the corresponding short side portion 130, however, the present invention is not limited thereto.

[0068] The fan front frame 10 further includes a plurality of (e.g., 2) second locking elements 500. The second locking element 500 includes a second stud 510 and a second screw hole 520. The second screw hole 520 passes through the second stud 510, and the axial direction (e.g., Z axis) of the second screw hole 520 is orthogonal to the long axis direction (e.g., Y axis) of the first reinforcing sheet 200 and the direction (e.g., X axis) facing the first main surface 211. The second stud 510 is embedded (or buried) in a lug portion 131 protruding from the other short side portion 130. In other words, at least one surface (e.g., circumferential surface) of each second stud 510 directly contacts the corresponding lug portion 131, however, the present invention is not limited thereto.

[0069] In the present embodiment, more specifically, the fan front frame 10 further includes a plurality of surrounding ribs 140, a reinforcing rib 150 and a grid pattern 160. Each surrounding rib 140 is convexly disposed on the inner surface 111 of the bottom plate 110 facing the inner groove space 170, and is located in the inner groove space 170. Each surrounding rib 140 surrounds and defines a slot 141. These slots 141 are linearly arranged along the long axis direction (such as the Y axis) of the bottom plate 110. The reinforcing rib 150 is convexly disposed on the inner surface 111 of the bottom plate 110, and passes through all the surrounding ribs 140 along the long axis direction (such as the Y axis) of the bottom plate 110 to provide a reinforcing structure for the frame body 100. The grid pattern 160 is formed and penetrates the bottom plate 110, so that each slot 141 is connected to the outside through the grid pattern 160, however, the utility model is not limited thereto.

[0070] For example, the surrounding ribs 140, the reinforcing ribs 150 and the grid pattern 160 are integrally formed with the frame body 100. The first reinforcing sheets 200 are respectively disposed in the long side portions 120 of the frame body 100 by an insert molding process; the first locking elements 400 and the second locking elements 500 are respectively disposed in the short side portions 130 of the frame body 100 by an insert molding process. In addition, the hardness of each first reinforcing sheet 200 is greater than the hardness of the frame body 100. For example, the first reinforcing sheet 200, the first locking element 400 and the second locking element 500 are, for example, metal objects, and the frame body 100 is, for example, a plastic frame. In other words, the material of the first reinforcing sheet 200 is metal or a material with higher hardness, and the material of the frame body 100 is plastic or the like.

[0071] However, the present invention is not limited to the number and shape of the first reinforcing sheet 200, the first locking element 400, and the second locking element 500. For example, in other embodiments, the number of the first reinforcing sheet 200 may be only one, and it is only embedded in one of the long side portions 120. The number of the first locking element 400 and the second locking element 500 may also be only one, and they are respectively embedded in the two short side portions 130.

[0072] Figure 4 It is a three-dimensional diagram of a fan front frame 11 according to an embodiment of the present invention. Figure 4 The fan front frame 11 and Figure 1The fan front frame 10 of the embodiment of the present invention is substantially the same as that of the fan front frame 11, and the difference is that the fan front frame 11 further includes a second reinforcing sheet 300. The second reinforcing sheet 300 is embedded (or buried) in the reinforcing rib 150, and the long axis direction (Y axis) of the second reinforcing sheet 300 is parallel to the long axis direction (Y axis) of the first reinforcing sheet 200 and the long axis direction (Y axis) of the reinforcing rib 150, and the hardness of the second reinforcing sheet 300 is greater than the hardness of the frame body 100. In this way, even if the thickness of the fan front frame 11 is insufficient, the structural strength can still be improved by the first reinforcing sheet 200 and the second reinforcing sheet 300.

[0073] For example, the second reinforcing sheets 300 are respectively disposed in the reinforcing ribs 150 of the frame body 100 by insert molding process.

[0074] In addition, for example, the first reinforcing sheet 200 and the second reinforcing sheet 300 are metal sheets. In other words, the materials of the first reinforcing sheet 200 and the second reinforcing sheet 300 are metal or materials with high hardness. Since the structure of the second reinforcing sheet 300 is the same as that of the first reinforcing sheet 200, it will not be described again.

[0075] Figure 5 FIG. 6 is a three-dimensional diagram of a fan assembly 600 according to an embodiment of the present invention. Figure 2 and Figure 5 As shown, the fan assembly 600 includes a fan front frame 610, a fan bottom cover 620, an adapter plate 630 and a plurality of fan units 650. The fan bottom cover 620 is disposed relative to the fan front frame 610. The fan front frame 610 can be the same as the above Figure 1 or Figure 4 The fan front frame 10, 11, however, the present invention is not limited thereto. The adapter plate 630 connects the fan front frame 610 and the fan bottom cover 620 respectively, and together defines a connecting inner tank space 170 ( Figure 1 ) of the accommodating space 640. The fan units 650 are respectively fixed and arranged in the accommodating space 640, and are respectively electrically connected to the adapter plate 630.

[0076] More specifically, in this embodiment, the fan front frame 610 is L-shaped, and the fan front frame 610 is locked on the fan front frame 610 by the first locking element 400, and is locked on the adapter plate 630 by the second locking element 500. A portion of each fan unit 650 extends into one of the slots 141 of the surrounding rib 140 ( Figure 1 ), so that the fan units 650 are linearly arranged in sequence along the long axis direction (such as the Y axis) of the frame body 100. Figure 5The fan assembly 600 further includes a handle 621. The handle 621 is pivotally disposed at one end of the fan bottom cover 620 opposite to the adapter plate 630, so that the user can use the handle 621 to pull the fan assembly 600 out of a server housing (not shown).

[0077] like Figure 5 As shown, the fan assembly 600 further includes a plurality of first shock absorbing pins 660 and a plurality of second shock absorbing pins 670. The first shock absorbing pins 660 respectively fix the fan units 650 to a side (such as the inner side 111) of the fan front frame 610 facing the accommodating space 640. The second shock absorbing pins 670 respectively fix the fan units 650 to a side (not shown) of the fan bottom cover 620 facing the accommodating space 640. In the present embodiment, the first shock absorbing pins 660 and the second shock absorbing pins 670 include shock absorbing materials such as rubber or plastic, however, the present invention is not limited thereto.

[0078] In addition, in the present embodiment, each first shock absorbing pin 660 separates the fan front frame 610 and the fan unit 650 from each other, so that a first distance G1 is provided between the fan front frame 610 and the fan unit 650. Each second shock absorbing pin 670 separates the fan bottom cover 620 and the fan unit 650 from each other, so that a second distance G2 is provided between the fan bottom cover 620 and the fan unit 650, so that vibration of the fan unit 650 during operation is not easily transmitted from the fan front frame 610 and the fan bottom cover 620. However, the present invention is not limited thereto.

[0079] Thus, through the above structure, the fan assembly and the fan front frame of the utility model can reduce the risk of deformation of the fan front frame, and prevent the fan unit therein from easily detaching from the fan front frame, thereby reducing costs and safety concerns.

[0080] 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.
