[0082] Figure 1 FIG. 1 is a perspective view of a bracket device 1 according to an embodiment of the present invention being installed on a two-column frame F1 . Figure 2 for Figure 1 A three-dimensional diagram of a bracket device 1 arranged on a four-post frame F2. Figure 3 for Figure 1 A three-dimensional view of the bracket device 1. Figure 4 for Figure 3 An exploded view of the bracket assembly 1 is shown. Two bracket assemblies 1 may be provided, one mounted on each opposing side wall of server S1. Bracket assemblies 1 are used to secure server S1 to a two-post rack F1 or a four-post rack F2. Server S1 may be a network communication server or a data processing server, but is not limited thereto.

[0083] Each bracket device 1 includes a fixed frame 10, a sliding frame 20, a connecting frame 30, and a handle 40. The fixed frame 10 is fixed to the side wall of the server S1's housing S10. The sliding frame 20 is slidably mounted on the fixed frame 10. The sliding frame 20 and the fixed frame 10 are elongated structures and extend along a longitudinal direction D1. The sliding frame 20 moves relative to the fixed frame 10 along the longitudinal direction D1. The connecting frame 30 is pivotally connected to one end of the sliding frame 20. The handle 40 is pivotally connected to the fixed frame 10 via a first rotation axis AX1. Therefore, the user can conveniently move the housing S10 by grasping the handle 40.

[0084] When the server S10 is installed on a two-post rack F1, one end of the fixed frame 10 is fixed to the main support column F10, and the sliding frame 20 is in a stowed position. When the server S10 is installed on a four-post rack F2, one end of the fixed frame 10 is fixed to the rear support column F20, the sliding frame 20 is unfolded relative to the fixed frame 10 to an extended position, and the connecting frame 30 is fixed to the front support column F30. Therefore, the bracket device 1 of this embodiment can be used to install the server S1 on either a two-post rack F1 or a four-post rack F2, thereby reducing the cost of installing the server S1 on racks of different specifications and improving installation convenience.

[0085] Figure 5 for Figure 3 1 , wherein the fixing bracket 10 is located in a disassembled position. Figure 6 for Figure 3 The front view of the fixing frame 10 in FIG. 1 , wherein the fixing frame 10 is located in a fixed position. In this embodiment, the server S1 further includes one or more first pins S11 and one or more second pins S12. The first pins S11 and the second pins S12 are disposed on the housing S10 (e.g. Figure 1 、 2 The first and second pins S11 and S12 are T-shaped. The fixing frame 10 includes a fixing body 11, a first locking hole 12, and a plurality of second locking holes 13. The fixing body 11 can be a plate-like structure extending along the longitudinal direction D1. The first and second locking holes 12 and 13 extend through the fixing body 11. The first pin S11 passes through the first locking hole 12, and the second pin S12 passes through the second locking hole 13.

[0086] The first locking hole 12 includes a first narrow portion 121 and a first wide portion 122. The first narrow portion 121 is connected to the first wide portion 122 and is aligned along the longitudinal direction D1. The width of the first narrow portion 121 is smaller than that of the first wide portion 122, and the widths are measured perpendicular to the longitudinal direction D1. The second locking hole 13 includes a second narrow portion 131 and a second wide portion 132.

[0087] The second narrow portion 131 is connected to the second wide portion 132 and is arranged along the longitudinal direction D1. The width of the second narrow portion 131 is smaller than the width of the second wide portion 132, and the aforementioned widths are measured in a direction perpendicular to the longitudinal direction D1. Figure 6 As shown, when the rod portion of the first pin S11 is located in the first narrow portion 121, the rod portion of the second pin S12 is located in the second narrow portion 131. Figure 5 As shown, when the rod portion of the first pin S11 is located in the first wide portion 122 , the rod portion of the second pin S12 is located in the second wide portion 132 .

[0088] When the fixing bracket 10 is located at a fixed position on the housing S10, as shown in FIG. Figure 6 As shown, the stem of the first pin S11 is located within the first narrow portion 121 of the first locking hole 12, and the stem of the second pin S12 is located within the second narrow portion 131. Because the width of the head of the first pin S11 is greater than the width of the first narrow portion 121, and the width of the head of the second pin S12 is greater than the width of the second narrow portion 131, the first pin S11 and the second pin S12 can prevent the fixing frame 10 from detaching from the casing S10 via the first narrow portion 121 and the second narrow portion 131.

[0089] In this embodiment, the bracket device 1 further includes a locking mechanism 50, which is disposed on the fixing frame 10 and adjacent to the first locking hole 12. The locking mechanism 50 is used to restrict or allow the first pin S11 to move in the first locking hole 12. In this embodiment, the locking mechanism 50 can be made of a metal plate and has a fixed end 51 and a free end 52. The fixed end 51 is fixed to the fixing frame 10, and the free end 52 covers the first wide portion 122. When the fixing frame 10 is installed on the housing S10, as shown in FIG. Figure 6 As shown, the free end 52 of the locking mechanism 50 abuts against the head of the first pin S11, thereby confining the stem of the first pin S11 within the first narrow portion 121, thereby confining the stem of the second pin S12 within the second narrow portion 131. Therefore, the locking mechanism 50 can secure the mounting bracket 10 to the housing S10.

[0090] When removing the fixing frame 10 from the housing S10, the locking mechanism 50 can be bent to separate the free end 52 of the locking mechanism 50 from the fixing frame 10. In some embodiments, the locking mechanism 50 may include a push rod 53, and the user can bend the locking mechanism 50 by moving the push rod 53. At this time, the locking mechanism 50 allows the first pin S11 to move in the first locking hole 12. Move the fixing frame 10 along the longitudinal direction D1 to Figure 5 The mounting bracket 10 is positioned so that the rod of the first pin S11 is located within the first wide portion 122 of the first locking hole 12, and the rod of the second pin S12 is located within the second wide portion 132. Because the width of the head of the first pin S11 is less than or equal to the width of the first wide portion 122, and the width of the head of the second pin S12 is less than or equal to the width of the second wide portion 132, the first pin S11 can pass through the first wide portion 122, and the second pin S12 can pass through the second wide portion 132, thereby allowing the mounting bracket 10 to be removed from the housing S10.

[0091] Therefore, in this embodiment, the user can install the bracket device 1 on the casing S10 or remove the bracket device 1 from the casing S10 without any additional tools.

[0092] The sliding frame 20 includes a main opening 21. The main opening 21 extends along the longitudinal direction D1, and its length is at least greater than half the length of the sliding frame 20. In this embodiment, the locking mechanism 50 may be located within the main opening 21. The fixed frame 10 further includes a plurality of guides 14 and a slide rail 15. The guides 14 are disposed on the fixed body 11. They are located within the main opening 21 and arranged along the longitudinal direction D1. In this embodiment, the guides 14 are T-shaped, with their stems located within the main opening 21 and their heads covering the edges of the main opening 21. The slide rail 15 is disposed on the fixed body 11 and located at an edge of the fixed body 11. The slide rail 15 extends along the longitudinal direction D1, with the edge of the sliding frame 20 located within the slide rail 15. Therefore, the guides 14 and / or the slide rail 15 can be used to limit the movement of the sliding frame 20 relative to the fixed frame 10 along the longitudinal direction D1.

[0093] The fixing frame 10 further includes a fixing plate 16 connected to the fixing body 11. The fixing plate 16 can extend perpendicularly to the fixing body 11. The bracket device 1 further includes one or more positioning bolts T1 and one or more locking members T2. The positioning bolts T1 and the locking members T2 can be set on the fixing plate 16 for insertion into the fixing body 11. Figure 1 Main support column F10 or Figure 2 The positioning bolts T1 secure the bracket assembly 1 to the main support column F10 or rear support column F20. The locking members T2 are secured to the main support column F10 or rear support column F20 via nuts (not shown) mounted on the main support column F10 or rear support column F20. The locking members T2 can be manually tightened into the nuts by the user. Therefore, no additional tools are required when installing the bracket assembly 1 to the two-post rack F1 or four-post rack F2.

[0094] Figure 7 for Figure 3 FIG. 1 is a partial cross-sectional view of the bracket device 1 in FIG. 1 , wherein the connecting frame 30 is located in a storage position. Figure 8 for Figure 3 FIG2 is a partial cross-sectional view of the bracket device 1 in FIG2 , wherein the connecting frame 30 is located in an installed position. The connecting frame 30 includes a rotating plate 31, a hook structure 32, and a connecting spring 33. The rotating plate 31 is pivotally connected to one end of the sliding frame 20 via a second rotating axis AX2. The hook structure 32 is movably disposed on the rotating plate 31. The connecting spring 33 is disposed on the rotating plate 31 and provides an elastic force to the hook structure 32. In this embodiment, the connecting frame 30 may further include a torsion spring (not shown) disposed on the second rotating axis AX2 to provide a torsional force between the rotating plate 31 and the fixed frame 10, thereby rotating the rotating plate 31 to the storage position.

[0095] like Figure 7As shown, when the sliding frame 20 is in the storage position, the hook structure 32 is engaged with a first hook groove 19 of the fixed body 11 of the fixing frame 10 and a second hook groove 22 of the sliding frame 20. Therefore, the hook structure 32 can limit the movement of the sliding frame 20 relative to the fixing frame 10.

[0096] like Figure 2 and Figure 8 As shown, when the bracket assembly 1 is installed on the four-post rack F2, the rotating plate 31 is rotated and the hook structure 32 is moved so that the hook structure 32 engages the front support column F30. Furthermore, a positioning pin T1 can be provided on the rotating plate 31 for insertion into the front support column F30. The positioning pin T1 secures the bracket assembly 1 to the front support column F30. Therefore, no additional tools are required when installing the bracket assembly 1 on the four-post rack F2.

[0097] Figure 9 for Figure 3 1, wherein the handle 40 is in a snap-on position. Figure 10 for Figure 3 The front view of the bracket device 1 in FIG. 4 shows a handle 40 in a gripping position. The bracket device 1 further includes an elastic element B1 (e.g. Figure 4 , is disposed on the first rotation axis AX1 and connects the handle 40 and the mounting frame 10. The elastic element B1 provides a torque to the handle 40, thereby rotating the handle 40 relative to the mounting frame 10. The bracket device 1 further includes a switching mechanism 60 disposed on the mounting frame 10 and positionable within the main opening 21. The switching mechanism 60 is used to restrain the handle 40 in the engaged position. Upon operating the switching mechanism 60 to release the handle 40, the elastic element B1 rotates the handle 40 relative to the mounting frame 10 to a gripping position.

[0098] The handle 40 includes a main body 41, a grip 42, a first latch 43, and a second latch 44. The main body 41 is pivotally connected to the fixing frame 10 via a first rotation axis AX1. The first rotation axis AX1 can be located in the main opening 21. The main body 41 can be a long strip-shaped structure. The grip 42, the first latch 43, and the second latch 44 are connected to the main body 41. The grip 42 and the main body 41 form an L-shape. The grip 42 is connected to one end of the main body 41, and the first latch 43 is connected to the other end of the main body 41. The grip 42, the main body 41, and the second latch 44 form a U-shape. When the handle 40 is in the engaged position, the grip 42 of the handle 40 does not protrude from the fixing frame 10 in the transverse direction D2 perpendicular to the longitudinal direction D1, thereby storing the handle 40 on one side of the fixing frame 10. When the handle 40 is located at the gripping position, the gripping portion 42 of the handle 40 protrudes from the fixing frame 10 and the sliding frame 20 in the transverse direction D2 , thereby facilitating gripping by the user.

[0099] The fixing frame 10 further includes a first stopper 17 and a second stopper 18. The first stopper 17 and the second stopper 18 are disposed on the fixing body 11 and are located within the main opening 21 of the sliding frame 20. The switching mechanism 60 includes a button 61 and a latch 62. When the button 61 is pressed, the latch 62 moves. When the button 61 is released, the latch 62 returns to its initial position due to a spring (not shown) within the switching mechanism 60. When the switching mechanism 60 restricts the handle 40 to the engaged position, the latch 62 engages with the first latching portion 43. The gripping portion 42 contacts or engages with the first stopper 17, the main body 41 contacts or engages with the second stopper 18, and the second latching portion 44 separates from the second stopper 18. Therefore, the switching mechanism 60, the first stopper 17, and the second stopper 18 allow the handle 40 to be securely stored on one side of the fixing frame 10.

[0100] like Figure 10 As shown, when the switching mechanism 60 releases the handle 40, the latch 62 disengages from the first latching portion 43. The gripping portion 42 separates from the first stopper 17, the body 41 separates from the second stopper 18, and the second latching portion 44 contacts or engages with the second stopper 18. Therefore, when the user grips the gripping portion 42 to lift the bracket device 1 and the housing S10 (as shown in FIG. Figure 1 and Figure 2 As shown), the second limit member 18 can prevent the handle 40 from moving relative to the fixing frame 10. Figure 10 Therefore, the user can conveniently lift the housing S10. When the handle 40 is stored, the handle 40 can be placed in the Figure 10 The handle 40 is rotated counterclockwise until the first latching portion 43 pushes the latch 62 toward the inside of the switching mechanism 60, and then the latch 62 pops out from the inside of the switching mechanism 60 and engages with the first latching portion 43, thereby completing the storage of the handle 40.

[0101] In summary, the bracket device of the present invention is applicable to both two-post racks and four-post racks, thereby increasing the convenience of configuring servers between two-post racks and four-post racks. In addition, the bracket device can be installed on the chassis without the use of tools, thereby improving installation convenience.

[0102] For ordinary technicians in this field, they can make other corresponding changes or adjustments based on the creative scheme and creative concept of the present invention in combination with the actual needs generated, and these changes and adjustments should fall within the scope of protection of the claims of the present invention.
