[0047] Please see Figures 1 to 5 . Figure 1 The illustration is a perspective view of a tray module according to one embodiment. Figure 2 The illustration shows a tray module in its stowed state according to one embodiment. Figure 3 The illustration shows a tray module in a lifted state according to one embodiment. Figure 4 The illustration shows a partial schematic diagram of the tray module in its stowed state according to one embodiment. Figure 5 The illustration shows a partial schematic of a tray module in a lifted state according to one embodiment. This invention discloses a tray module 100 adapted to a chassis 200 in one embodiment. The chassis 200 includes at least two side panels 1A and 1B. The tray module 100 can be assembled to the chassis 200 and used to carry expansion components, such as hard disk drives, circuit boards, etc. In some embodiments, the chassis 200 is part of a rack server rack for accommodating one or more rack servers and expansion components. The rack server height is measured in U (1U equals 1.75 inches, which equals 44.45 millimeters). The rack is, for example, but not limited to, a rack for accommodating standard rack servers from 1U to 7U.

[0048] like Figure 4 as well as Figure 5As shown, each side plate 1A, 1B has a slide rail 10. In some embodiments, the slide rail 10 may be, for example, a groove or a track; a groove is used as an example, but this is not a limitation. The slide rail 10 includes a first horizontal section 101, an inclined section 102, and a second horizontal section 103. The inclined section 102 is connected to the first horizontal section 101, and the second horizontal section 103 is connected to the inclined section 102. The side plates 1A, 1B are configured in an even number, such as two, four, or six. The first horizontal section 101, the inclined section 102, and the second horizontal section 103 of these slide rails are roughly S-shaped. The shape of the slide rail 10 has various embodiments, and the detailed shape structure will be described in detail later. The following description uses an S-shaped slide rail as an example, but this is not a limitation. In some embodiments, each side plate 1A, 1B has the same corresponding structure. Figure 4 as well as Figure 5 The example is taken from only one side panel 1A. The inclined segment 102 is inclined relative to the first horizontal segment 101 and the second horizontal segment 103.

[0049] like Figures 2 to 5 As shown, the tray module 100 includes a platform body 30, two first links 31, and two second links 32. Each first link 31 has a movable end 311 and a driven end 312. Each movable end 311 is pivotally connected to both sides of the platform body 30 and slides along the slide rail 10. Each second link 32 has a pivot end 321, a pivot portion 322, and an operating end 323. The pivot portion 322 is located between the pivot end 321 and the operating end 323. Each pivot end 321 is pivotally connected to the side plates 1A and 1B. Each driven end 312 is pivotally connected to the pivot portion 322. In some embodiments, each first link 31 and each second link 32 has the same corresponding structure. Figure 4 as well as Figure 5 The example only uses the first link 31 and the second link 32 on one side. The moving end 311 and the driven end 312 of the first link 31 are located at opposite ends, meaning the driven end 312 is located at the end furthest from the moving end 311. The pivot end 321 and the operating end 323 are located at opposite ends of the second link 32. Figure 2 as well as Figure 4 As shown, when the tray module 100 is in the retracted state, the moving end 311 of the first link 31 is located at the leftmost position of the first horizontal segment 101 (within the case of...). Figure 4 (View orientation). For example... Figure 3 as well as Figure 5 As shown, during operation, the user holds handle 9 and moves towards... Figure 4Pulling up the right and top sides of the view moves the tray module 100 to the lifted state, at which point the moving end 311 is located in the second horizontal segment 103. The smaller the inclination angle of the tilt segment 102 relative to the first horizontal segment 101, the less effort the platform body 30 needs to exert during its travel in the tilt segment 102. The connection points of the first horizontal segment 101, the tilt segment 102, and the second horizontal segment 103 are, for example, rounded or obtuse angles, allowing the moving end 311 to slide more smoothly between the first horizontal segment 101 and the second horizontal segment 103.

[0050] Specifically, the tray module 100 is adapted to the housing 200. The housing 200 includes at least two side plates 1A and 1B. Each of the at least two side plates 1A and 1B has a slide rail 10. The tray module 100 includes a platform body 30, two first links 31, and two second links 32. The moving end 311 of the first link 31 is pivotally connected to the platform body 30 and slides on the slide rail 10. The pivot end 321 of the second link 32 is pivotally connected to the side plates 1A and 1B, and the pivot portion 322 of the second link 32 is pivotally connected to the driven end 312 of the first link 31. By operating the operating end 323 of the second link 32, the platform body 30 moves between the first horizontal section 101 and the second horizontal section 103, achieving the effect of effortless and easy assembly of the tray module 100 into the housing 200.

[0051] Each first link 31 has a protrusion 313, each protrusion 313 being disposed on the moving ends 311 and movably accommodated in the slide rails 10.

[0052] like Figure 4 as well as Figure 5 As shown, the tray module 100 also includes an elastic element 5, which is disposed on the housing 200. At least one of the two second connecting rods 32 is provided with a hook portion 324, which is located between the pivot end 321 and the operating end 323. The elastic element 5 is adjacent to and connected to the hook portion 324. The elastic element 5 is disposed only on one side of the housing 200, but is not limited thereto. Figure 4 as well as Figure 5 Taking side panel 1A as an example, an elastic element 5 is disposed on the side of the housing 200 and adjacent to side panel 1A. A hook portion 324 cooperating with the elastic element 5 is provided on the second connecting rod 32 at side panel 1A. The hook portion 324 is located between the pivot end 321 and the pivot portion 322. The elastic element 5 engages with the hook portion 324. The elastic force of the elastic element 5 provides an upward lifting force, lifting the second connecting rod 32 and moving the moving end 311 of the first connecting rod 31 from the first horizontal segment 101 to the second horizontal segment 103, causing the tray module 100 to change from a retracted state to a lifted state. In some embodiments, the elastic element 5 is a tension spring. Specifically, as... Figure 4As shown, when the tray module 100 is in the stowed state, the movable end 311 is located in the first horizontal segment 101 and the elastic element 5 is in the extended state. When the tray module 100 is to be lifted, the user moves the movable end 311 to the second horizontal segment 103 using the handle 9, as shown. Figure 5 As shown, when the moving end 311 is in the second horizontal segment 103, the elastic element 5 is in a contracted state and lifts the second connecting rod 32, thereby achieving the effects of saving effort and automatic return through the elastic element 5.

[0053] Please see Figure 4 as well as Figure 5 In some embodiments, the tray module 100 includes a positioning assembly 7, which includes an actuating element 70 and a torsion spring 71. The actuating element 70 is disposed on the housing 200. The actuating element 70 is adjacent to the pivot end 321 of one of the two second links 32. One end of the torsion spring 71 abuts against the housing 200, and the other end abuts against the actuating element 70. The actuating element 70 includes an actuating element body 701 and a protrusion 702 protruding toward the pivot end 321. The pivot end 321 is provided with a sliding portion 325, which includes a first end 3251, a second end 3252, a recess 3253, and two stops 3254A and 3254B. The first end 3251 and the second end 3252 are opposite ends. The recess 3253 is adjacent to the first end 3251. Two stop portions 3254A and 3254B are respectively provided at the first end 3251 and the second end 3252. The protrusion 702 of the actuating member 70 is selectively accommodated in the recess 3253 or located at the second end 3252. In this embodiment, the actuating member 70 is only provided on one side of the housing 200, but it is not limited thereto. The tray may also include two positioning components 7. The actuating member 70 is provided on the side of the housing 200 and adjacent to the pivot end 321 of the second connecting rod 32. The second connecting rod 32 at the side plate 1A is provided with a sliding portion 325 that cooperates with the actuating member 70. The sliding portion 325 is provided at the pivot end 321. Specifically, as Figure 4 As shown, when the tray module 100 is in the retracted state, the protrusion 702 of the actuating member 70 is accommodated in the recess 3253 of the sliding portion 325 and abuts against the stop portion 3254A of the first end 3251, so that the second connecting rod 32 is fixed and stably keeps the tray module 100 in the retracted state. Figure 5As shown, when the user wants to lift the tray module 100, the user moves the actuating member 70, causing the protrusion 702 to disengage from the recess 3253, thus releasing the fixation of the second link 32. The user can then lift the second link 32 to move the moving end 311 of the first link 31 from the first horizontal segment 101 to the second horizontal segment 103. When the moving end 311 is in the second horizontal segment 103, that is, when the second link 32 is lifted, the protrusion 702 of the actuating member 70 abuts against the stop 3254B of the second end 3252 of the sliding portion 325. The actuating member 70 achieves the effect of positioning the tray module 100 in both the stowed and lifted states. Specifically, as... Figure 4 As shown, the torsion spring 71 continuously provides a counterclockwise direction ( Figure 4 The spring force (from the user's perspective) accommodates the protrusion 702 within the recess 3253, while positioning the movable end 311 in the first horizontal segment 101. When the user applies force clockwise to overcome the spring force of the torsion spring 71, as... Figure 5 As shown, the actuating member 70 disengages from the recess 3253, and the pivot end 321 of the second link 32 can pivot because the positioning is released. When the moving end 311 is located in the second horizontal section 103, the protrusion 702 is located in the second end 3252, and the moving end 311 is positioned in the second horizontal section 103.

[0054] The slide rail 10 has various shapes and embodiments. Please refer to [link / reference]. Figure 6 as well as Figure 7 . Figure 6 The diagram illustrates the movement of a tray module according to one embodiment (a). Figure 7 The illustration shows a schematic diagram (II) of the movement of a tray module according to one embodiment. Specifically, as follows... Figure 6 As shown, the transverse groove of the first horizontal segment 101, the oblique vertical groove of the inclined segment 102, and the transverse groove of the second horizontal segment 103 make the first horizontal segment 101, the inclined segment 102, and the second horizontal segment 103 slightly S-shaped. In some embodiments, the stage body 30 carries an extension element. Figure 6 The displayed expansion component is circuit board 34. When the tray module 100 is in the retracted state, the left side of circuit board 34 ( Figure 6Connector 341 (from the user's perspective) is electrically connected to connector 510 of external system 500, enabling external system 500 to operate. When the user wants to move tray module 100 to the lifted state, they pull the handle to the right, causing the platform body 30 to move from the left end to the right end of the first horizontal section 101, causing connectors 510 and 341 to separate, thus disconnecting the electrical connection between circuit board 34 and external system 500. Next, the user continues to pull the handle, causing the platform body 30 to climb along the inclined section 102 to the upper right, avoiding the first housing structure 210 and the second housing structure 220 located on the left and right sides of housing 200, respectively. When the platform body 30 moves to the rightmost side of the inclined section 102, the user can move the platform body 30 to the right along the second horizontal section 103, pulling the platform body 30 outwards from housing 200 to facilitate the replacement and maintenance of the circuit board on the platform body 30. In some embodiments, the first housing structure 210 and the second housing structure 220 are, for example, a frame, platform, or a structure of the housing itself that is designed due to its shape and mounted on the housing.

[0055] Please refer to Figure 7 In one embodiment, each side panel 1A, 1B has a slide rail 10, which includes a first horizontal segment 101 and an inclined segment 102 connected to the first horizontal segment 101. The side panels 1A, 1B are configured in an even number, such as two, four, or six. The inclined segment 102 is inclined relative to the first horizontal segment 101. In some embodiments, the first horizontal segment 101 and the inclined segment 102 may also be slightly L-shaped. Specifically, as... Figure 7 As shown, the first horizontal segment 101 is a generally horizontal groove, and the inclined segment 102 is a generally oblique vertical groove, which together make the first horizontal segment 101 and the inclined segment 102 slightly L-shaped. The user switches the tray module 100 between the stored state and the lifted state by moving the movable end 311 between the first horizontal segment 101 and the inclined segment 102.

[0056] Please refer to it again. Figure 4 as well as Figure 5In some embodiments, the pivot end 321 to the pivot portion 322 of each second link 32 is a first segment 32A, and the pivot portion 322 to the operating end 323 is a second segment 32B. The second segment 32B is inclined to the first segment 32A. When the moving end 311 is located in the second horizontal segment 103, the first segment 32A and the first link 31 have a first angle D1. When the moving end 311 is located in the first horizontal segment 101, the first segment 32A and the first link 31 have a second angle D2. The first angle D1 is smaller than the second angle D2. Specifically, the second segment 32B is inclined towards the first segment 32A to prevent the second segment 32B of the second link 32 from hitting or touching the housing 200 when the tray module 100 is in the retracted state. When the tray module 100 is in the retracted state, the moving end 311 is located in the first horizontal segment 101, and the first segment 32A and the first link 31 have a first angle D1. When the tray module 100 is in the lifted state, the moving end 311 is located in the second horizontal segment 103, and there is a second included angle D2 between the first segment 32A and the first link 31. That is, when the moving end 311 moves from the first horizontal segment 101 to the second horizontal segment 103, the included angle between the first segment 32A of the second link 32 and the first link 31 increases.

[0057] See again Figure 2 as well as Figure 3 In some embodiments, the tray module 100 further includes a handle 9, which is located at the operating end 323 of the two second links 32 and connects the two second links 32. Specifically, the handle 9 connects the second links 32 on both sides of the platform body 30, and the second links 32 are lifted by pulling the handle 9.

[0058] Please see Figure 8 And refer to again Figure 2 as well as Figure 3 . Figure 8 The illustration shows a partial schematic diagram of the side panels of a tray module according to one embodiment. In some embodiments, there are, for example, four side panels, and each movable end 311 of the two first links 31 is pivotally connected to both sides of the platform body 30 and movably accommodated in the slide rails 10 of two of the four side panels 1A, 1B, 1C, 1D. The platform body 30 has two protrusions 33A, 33B on both sides, and the platform body 30 is movably accommodated in the slide rails 10 of the other two of the four side panels 1A, 1B, 1C, 1D via the two protrusions 33A, 33B. Each movable end 311 of the two first links 31 is pivotally connected to the rear end of the platform body 30 (i.e., Figure 2 The slide rails 10, which are movably accommodated on both sides of the right side of the platform body 30 (viewed from the right), are located on the two side plates 1A and 1B. Figure 2 Two protrusions 33A and 33B are provided on both sides of the left side of the viewpoint, as shown. Figure 8 As shown, the platform body 30 is movably accommodated in the slide rails 10 of the two side plates 1C and 1D via two protrusions 33A and 33B, respectively. The two side plates 1C and 1D have the same structural configuration. Figure 8 The example shown uses only one side plate 1C. In another embodiment, there are six side plates, which are respectively located at the front, middle and rear sections of the platform body to increase the stability of the platform body.
