Description

Slide rail assembly

The present invention relates to a slide rail assembly, and more particularly to a slide rail assembly suitable for at least two cabinets and having at least two chassis having the same chassis width.

In general, in a server system, the server chassis is mounted on a rack by means of a pair of rail assemblies. Wherein, the slide rail assembly is usually a two-section or three-section slide rail to carry the server chassis. The difference between the two is that the three-section slide can have a longer extension to meet the specific needs of the practice.

However, due to structural design factors, three-section slides currently on the market are generally not capable of being installed with two chassis of the same width.

First, as shown in FIG. 11A to FIG. 11D, when the operator pulls the third rail 26 into the opening direction D1 by means of the operating member 30 (FIG. 11A, FIG. 11B), the third rail 26 The hook portion 148 correspondingly abuts the protrusion 110 of the actuating member 100, and the second rail 24 is displaced by the third rail 26 until the second rail 24 is pulled out relative to the first rail 22 to a predetermined position. In position, the projection 110 of the actuator 100 can be guided by the guide portion 78 of the first rail 22 to be disengaged from the hook portion 148 of the third rail 26 (as in FIGS. 11C, 11D). In detail, when the projection 110 of the actuator 100 is displaced from the horizontal section 80 of the guiding portion 78 of the first rail 22 to the rising section 82 of the guiding portion 78, the actuator 100 is extended by the tail 112.

The bump 110 is easily detached from the hook portion 148 of the third rail 26 (as shown in FIG. 11C), and then the bump 110 of the actuator 100 continues to be guided by the rising portion 82 of the guiding portion 78 to be displaced thereto. The retaining wall 84 of the guide portion 78 (as shown in FIG. 11D) causes the bump 110 to be blocked by the retaining wall 84 of the guiding portion 78. And as shown in FIG. 11B and FIG. 11C, the elastic force generated by the elastic guiding portion 96 of the auxiliary member 88 causes the leg portion 92 of the swinging member 86 to be guided to enter and abut against the concave portion of the second rail 24. 114. That is, the recess 114 of the second rail 24 can correspondingly abut the leg portion 92 of the swinging member 86.

As shown in FIG. 11D, when the projection 110 of the actuator 100 is blocked by the retaining wall 84 of the guiding portion 78 of the first rail 22, the leg portion 92 of the swinging member 86 enters the recess of the second rail 24. At 114 o'clock, the second rail 24 is no longer displaced synchronously with the third rail 26. At this time, the third rail 26 can continue to be displaced in the opening direction D1.

As shown in FIG. 12 to FIG. 15 , in the process in which the third rail 26 continues to be displaced in the opening direction D1, since the elastic portion 146 of the latching member 140 has the capability of elastic bending, the third rail 26 has not yet been When the displacement reaches a position, the elastic portion 146 is pressed between the second rail 24 and the third rail 26 to be in a state of elastic pressure accumulation (as shown in FIGS. 12 and 14); until the third rail When the displacement is continued to the position, the elastic portion 146 releases the elastic force, so that the positioning portion 142 of the latching member 140 can enter the opening 152 of the first longitudinal portion 32 of the third rail 26 to be engaged and corresponding thereto. An opening wall 153 of the opening 152. At this time, the third rail 26 is in an open position (as shown in FIGS. 13 and 15).

As shown in FIGS. 16-18, when the third rail 26 is in the open position and the operator wants to detach the third rail 26 from the second rail 24, the operator only needs to move from the third rail 26 The opening 152 applies a force F1 (as shown in FIG. 18) to the elastic portion 146 of the latching member 140, so that the positioning portion 142 of the elastic portion 146 is separated from the opening 152 and no longer corresponds to the opening wall surface 153. The operator can withdraw the third rail 26 to a disassembly direction D2 (as in FIG. 17) to detach the third rail 26 from the second rail 24.

As shown in FIGS. 19A-19D, after the third rail 26 is detached, the operator can further detach the second rail 24 from the first rail 22. The operator can apply a force F2 (such as FIG. 19B) to pull the operating portion 128 of the release member 120 such that the movable portion 122 of the release member 120 is displaceable relative to the limiting member 118 by the longitudinal groove 126. According to this, with the release member 120 The untwisting portion 124 is interlocked such that the untwisting edge 136 can correspondingly drive a portion of the swinging member 86 (eg, the extended side portion 94) (at this time, the flexible body 130 is subjected to the force of the blocking member 138) In a curved state, the leg portion 92 of the swinging member 86 is displaced to be disengaged from the recess 114 of the second rail 24 again. In this state, the operator can withdraw the second rail 24 in a disassembly direction D3 to detach the second rail 24 from the first rail 22 (as shown in Fig. 19C). After the operator stops applying the force F2 and pulls the operating portion 128, the flexible body 130 drives the release member 120 to return to the initial state again (as shown in FIG. 19D).

It can be seen from the above-mentioned FIG. 16 to FIG. 19 that the third rail 26 and the second rail 24 of the slide rail assembly can be detached, so that the operator can replace the chassis (eg, the server chassis) or perform the slide rail assembly. Replacement, repair, etc.

As shown in FIG. 20A to FIG. 20C, when the operator wants to displace the slide rail assembly from the above-mentioned open position (as shown in FIG. 13) to a folding direction D4, the operator can press the same. The elastic portion 146 of the latching member 140 (as in the state of FIG. 18), and the third rail 26 is displaced to the folding direction D4, so that the second rail can be pushed by the inclined portion 36 of the third rail 26 24, the third rail 26 and the second rail 24 can be folded relative to the first rail 22. When the second rail 24 is displaced to a position, the guiding slope 150 of the hook portion 148 of the third rail 26 can correspondingly push the protrusion 110 of the actuating member 100 to make the actuator 100 convex. The block 110 is supported by the guiding ramp 150 away from the retaining wall 84 of the guiding portion 78 of the first rail 22 (as shown in FIG. 20B); and the inclined surface 116 of the second rail 24 pushes the foot of the swinging member 86 92, the foot portion 92 is offset away from the recess 114 (as shown in Fig. 20C). Accordingly, the bump 110 of the actuating member 100 can be again hooked by the hook portion 148 of the third rail 26, so that the third rail 26 and the second rail 24 are folded with the first rail 22. (This section can also refer to Figure 11A).

Figure 21 shows a server system 200 including a rack 202 (or machine) a cabinet, a first chassis 204, a second chassis 206, and a pair of rail assemblies 20. The first rail 22 of each of the slide rail assemblies 20 is mounted to the frame 202; and the second rails 24 and the third rails 26 are stretched relative to the first rails 22 to be in an open state. The related structure and arrangement of the slide rail assembly 20 have been found in the above embodiments. For the sake of brevity, the slide rail assembly 20 will not be described herein.

The two opposite sides of the first chassis 204 are correspondingly mounted to the longitudinally extending body 56 of the second rail 24 by means of at least one mounting member (the mounting member of the first chassis 204 is not shown due to the viewing angle). The portion 28 (this portion can be simultaneously referred to FIG. 1); similarly, the opposite sides of the second chassis 206 are supported by at least one mounting member 208 (the mounting member on the other side is not shown due to the viewing angle). Corresponding to the mounting portion 28 of the second longitudinal portion 34 of the third rail 26 (this portion can be simultaneously referred to FIG. 1).

Referring to FIG. 21 and FIG. 1, since the side surface of the second longitudinal portion 34 of the third rail 26 and the side surface of the longitudinally extending body 56 of the second rail 24 are located at substantially the same reference plane, the first The chassis width W1 of the chassis 204 and the chassis width W2 of the second chassis 206 may be the same. That is, the second rail 24 and the third rail 26 of the rail assembly 20 can be mounted to a chassis of the same width.
