The second support plate of the second slide rail module is movably arranged on the first support plate, so that the weight of the second slide rail module can be applied to the first support plate instead of the first slide rail device, and the risk of damage caused by deformation of the first slide rail device can be reduced.

Description

Technical Field

[0001] This invention relates to a slide rail system, and more particularly to a slide rail system with relative movement function. Background Technology

[0002] An existing sliding rail system is suitable for a server rack and can accommodate a server chassis. When a user wants to replace or maintain the server chassis, it can be easily pulled out using the sliding rail system. However, when the length of the server rack and sliding rail system significantly exceeds the length of the server chassis, space is inevitably wasted. A current improvement involves adding another sliding rail device to the system, with a length slightly less than the length difference between the server rack and the server chassis, allowing one sliding rail device to move relative to the other. The added sliding rail device can then support additional mechanisms. However, if the added sliding rail device is directly mounted on the original sliding rail device, it may compress and deform the original sliding rail device during movement, resulting in obstructed movement. Therefore, there is still room for improvement. Summary of the Invention

[0003] One object of the present invention is to provide a slide rail system that can solve at least one of the above-mentioned problems.

[0004] The slide rail system of the present invention includes a first slide rail module, including a first support plate and a first slide rail device disposed on the first support plate; and a second slide rail module, including a second support plate movably disposed on the first support plate and a second slide rail device disposed on the second support plate.

[0005] In some embodiments, the first support plate has a bottom wall, two side walls formed on the upper and lower sides of the bottom wall, and an upper extension wall formed on the upper side wall, and the second support plate is movable along the upper extension wall.

[0006] In some embodiments, the second support plate has a first surface for the second slide rail device and a second surface opposite to the first surface. The second slide rail module also includes a plurality of sliding aids disposed on the second surface and abutting against the side wall above.

[0007] In some embodiments, the second slide rail module also includes multiple upper limit members disposed on the second support plate and located on both sides of the upper extension wall.

[0008] In some embodiments, the second support plate has a plurality of L-shaped limiting pieces formed on the second surface. Each upper limiting piece has a mounting portion disposed on the first surface and a limiting portion connected to the mounting portion, passing through the second support plate and abutting against the corresponding limiting piece. The limiting portion is inverted U-shaped and located on both sides of the upper extension wall.

[0009] In some embodiments, the first support plate also has a lower extension wall formed on the lower side wall, and the second slide rail module also includes a plurality of lower limiting members disposed on the second support plate and located on both sides of the lower extension wall.

[0010] In some embodiments, the bottom wall has a first end and a second end opposite to the first end, and the first slide rail module also includes a stop disposed at the first end.

[0011] In some embodiments, the lower extension wall has a stop portion that protrudes downward at the second end.

[0012] The present invention has at least the following advantages: by having the second support plate of the second slide rail module movably disposed on the first support plate, the weight of the second slide rail module will be applied to the first support plate instead of the first slide rail device, thereby reducing the risk of deformation and damage to the first slide rail device.

[0037] See Figure 1 and Figure 2 An embodiment of the slide rail system 10 of the present invention includes a first slide rail module 1 and a second slide rail module 2 movably disposed on the first slide rail module 1.

[0038] See Figures 2 to 4The first slide rail module 1 includes a first support plate 11 extending along a horizontal direction D1, a first slide rail device 12 disposed on the first support plate 11, a bracket 13 disposed on the first support plate 11, and a stop member 14 disposed on the first support plate 11. The first support plate 11 has a bottom wall 111, two side walls 112 formed on the upper and lower sides of the bottom wall 111, an upper extension wall 113 formed on the upper side wall 112, and a lower extension wall 114 formed on the lower side wall 112. The bottom wall 111 has a first end 111a and a second end 111b opposite to the first end 111a. The upper side wall 112 forms a first locking hole 112a and a second locking hole 112b spaced apart from the first locking hole 112a and located at the second end 111b. The upper extension wall 113 has a movable portion 113a extending from the first end 111a toward the second end 111b, a raised portion 113b connecting the movable portion 113a and extending to the second end 111b, and a protrusion 113c formed in the raised portion 113b and adjacent to the second end 111b. The raised portion 113b has a height greater than the height of the movable portion 113a in a vertical direction D2 perpendicular to the horizontal direction D1 and has a stop point 113b 1 adjacent to the movable portion 113a. The lower extension wall 114 has a stop portion 114a protruding downward at the second end 111b. The first slide rail device 12 has a first outer rail 121 fixedly disposed on the first support plate 11, a first middle rail 122 movably disposed on the first outer rail 121, and a first inner rail 123 movably disposed on the first middle rail 122. The bracket 13 is disposed at the second end 111b of the first support plate 11. The stop 14 is disposed at the first end 111a to prevent the second slide rail module 2 from disengaging from the first slide rail module 1.

[0039] See Figures 5 to 7The second slide rail module 2 includes a second support plate 21 movably disposed on the first support plate, a second slide rail device 22 disposed on the second support plate 21, a locking member 23 movably disposed on the second support plate 21 and extending into the first locking hole 112a, an unlocking member 24 movably disposed on the second support plate 21, a locking member 25 disposed on the second support plate 21, three sliding aids 26 spaced apart on the second support plate 21, two upper limit members 27 disposed on the second support plate 21, three lower limit members 28 disposed on the second support plate 21, an unlocking elastic member 29 disposed on the second support plate 21, and a locking elastic member 20 disposed on the second support plate 21. The second support plate 21 has a first surface 211 for the second slide rail device 22, a second surface 212 opposite to the first surface 211, a movable groove 213 extending along the vertical direction D2, two mounting grooves 214 extending along the vertical direction D2 and located on both sides of the movable groove 213, two sleeve clamps 215 formed on the second surface 212, an unlocking hook 216 formed on the first surface 211, a locking hook 217 formed on the first surface 211, and two L-shaped limiting pieces 218 formed on the second surface 212. The aforementioned stop portion 114a can be used to stop the second support plate 21 and prevent the second support plate 21 from detaching from the first support plate 11 at the second end 111b.

[0040] The second slide rail device 22 has a second outer rail 221 disposed on the first surface 211, a second middle rail 222 movably disposed on the second outer rail 221, and a second inner rail 223 movably disposed on the second middle rail 222. The second middle rail 222 has a central hook 222a.

[0041] See Figure 6 , Figures 8 to 10The locking member 23 is disposed on the second support plate 21 by a positioning member 236, and includes a flat plate portion 231 movably disposed on the second surface 212, a generally U-shaped enclosure portion 232 formed on the flat plate portion 231 extending away from the second surface 212, a latching portion 233 formed on the enclosure portion 232 and extending into the first locking hole 112a, and two sleeve portions 234 formed on both sides of the enclosure portion 232. The flat plate portion 231 has a protrusion 231a that passes through the movable groove 213 and abuts against the unlocking member 24, and two protrusions 231b that can be correspondingly accommodated in the mounting groove 214. The latching portion 233 has an abutting section 233a that abuts against the side wall 112 and an engaging section 233b that extends downward from the abutting section 233a and extends into the first locking hole 112a. Each sleeve portion 234 has a receiving groove 234a, which allows the sleeve clamping block 215 to extend into its upper end and can accommodate two locking elastic members 235. One end of each locking elastic member 235 abuts against the corresponding sleeve clamping block 215, and the other end abuts against the bottom of the sleeve portion 234.

[0042] See Figures 5 to 7 and Figure 11 The unlocking member 24 has an annular operating portion 241, a movable portion 242 connected to the operating portion 241 and movably disposed on the first surface 211 along the horizontal direction D1, an unlocking groove 243 formed through the movable portion 242, and a hook portion 244 connected to the movable portion 242. The protrusion 231a passes through the unlocking groove 243 and abuts against the movable portion 242. The unlocking groove 243 has an inclined section 243a and an unlocking section 243b connected to the inclined section 243a. The width of the inclined section 243a in a vertical direction D2 perpendicular to the horizontal direction D1 gradually decreases towards the unlocking section 243b. The width of the unlocking section 243b in the vertical direction D2 is greater than the width of the inclined section 243a adjacent to the end of the unlocking section 243b. The movable part 242 has a slope 242a located below the inclined section 243a and a locking point 242b located between the inclined section 243a and the unlocking section 243b. The unlocking elastic member 29 connects the hook 244 and the unlocking hook 216.

[0043] See Figures 5 to 7 The latching member 25 has a generally L-shaped body portion 251 pivotally mounted on the first surface 211, a latching portion 252 extending from one end of the body portion 251 away from the second support plate 21, an abutment portion 253 extending from the other end of the body portion 251 and passing through the second support plate 21, and a latching hook portion 254 connecting the body portion 251 and adjacent to the abutment portion 253. The latching portion 252 can be latched onto the latching hook 222a. The latching elastic member 20 connects the latching hook portion 254 and the latching hook 217.

[0044] See Figures 6 to 8 The sliding aid 26 is disposed on the second surface 212 and abuts against the upper side wall 112, enabling the second slide rail module 2 to slide more smoothly relative to the first support plate 11. Specifically, the sliding aid 26 is a roller, but this is not a limitation, and its number is not limited to three, as long as there are multiple rollers. The upper limit member 27 is disposed on the second support plate 21 and located on both sides of the upper extension wall 113. Each upper limit member 27 has a mounting part 271 disposed on the first surface 211 and a limiting part 272 connected to the mounting part 271, passing through the second support plate 21 and abutting against the corresponding limiting piece 218. The limiting part 272 is inverted U-shaped and located on both sides of the upper extension wall 113, allowing the upper extension wall 113 to extend into and be limited. The lower limiting member 28 is disposed on the second support plate 21 and located on both sides of the lower extension wall 114, allowing the lower extension wall 114 to extend into and be limited. By providing the upper limiting member 27 and the lower limiting member 28, the frictional force of the second slide rail module 2 sliding relative to the first support plate 11 can be reduced, thus allowing the second slide rail module 2 to slide more smoothly relative to the first support plate 11. It should be noted that the number of the sliding aid 26, the upper limiting member 27, and the lower limiting member 28 is not limited to this embodiment; other numbers can be used in other embodiments, as long as there are multiple components.

[0045] See Figures 11 to 14 The unlocking member 24 can be operated to move between a locked position and an unlocked position. In the locked position, the protrusion 231a of the locking member 23 abuts against the movable part 242 and is located at the end of the inclined section 243a away from the unlocking section 243b and the lower end of the movable groove 213. The engaging section 233b extends into the first locking hole 112a. At this time, the second support plate 21 cannot move relative to the first support plate 11. The operating part 241 can be operated to move away from the second support plate 21 in the horizontal direction D1, so as to drive the protrusion 231a to move upward along the inclined surface 242a and the movable groove 213, and finally enter the unlocking section 243b and be stopped by the locking point 242b to reach the unlocked position. In the unlocked position, the engaging section 233b disengages from the first locking hole 112a, allowing the second support plate 21 to move relative to the first support plate 11. At this time, the unlocking elastic element 29 is in a stretched state, and the locking elastic element 235 (see...) Figure 6 It is in a compressed state to accumulate elastic restoring force.

[0046] See Figure 15 and Figure 16When the second support plate 21 continues to move toward the second end 111b, the enclosure portion 232 of the locking member 23 will abut against the protrusion 113c and be pushed upward by the protrusion 113c, causing the protrusion 231a to move upward and separate from the locking point 242b. At this time, the operating portion 241 of the unlocking member 24 is pulled by the elastic restoring force of the unlocking elastic member 29 to move toward the second support plate 21 in the horizontal direction D1 to return to the locked position. At this time, the protrusion 231a of the locking member 23 is still located at the upper end of the inclined section 243a of the unlocking groove 243. Figure 16 As shown. See next. Figure 5 and Figure 17 After the enclosure portion 232 passes the protrusion 113c, the elastic restoring force of the locking elastic member 235 pushes the locking member 23 downward, causing the engaging section 233b of the locking block portion 233 to extend into the second locking hole 112b, thereby positioning the second support plate 21 relative to the first support plate 11. Figure 17 As shown.

[0047] See Figure 5 , Figure 18 and Figure 19 During the movement of the second support plate 21 relative to the first support plate 11, specifically before the second support plate 21 moves to the second end 111b, the abutment part 253 will abut against the stop point 113b1 and drive the locking part 252 to pivot upward, so as to release the locking relationship between the locking part 252 and the middle hook 222a, and the second middle rail 222 can then extend relative to the second outer rail 221.

[0048] In summary, the slide rail system 10 of the present invention is movably disposed on the first support plate 11 by means of the second support plate 21 of the second slide rail module 2. The weight of the second slide rail module 2 will be applied to the first support plate 11 instead of the first slide rail device 12, which can reduce the risk of deformation and damage of the first slide rail device 12. Therefore, the purpose of the present invention can indeed be achieved.
