Slide rail integration

Abstract

A slide rail assembly is adapted to be disposed on a first side of a first housing. The slide rail assembly includes an outer slide rail, an inner slide rail, a first engaging member and a second engaging member. The outer slide rail includes a first hook. The inner slide rail is slidably disposed in the outer slide rail and includes a first end, a second end and a plurality of positioning slots. A plurality of first fixing portions of the first housing are engaged with some of the positioning slots so that the first housing is fixed to the inner slide rail. The first engaging member partially overlaps a critical positioning slot of the positioning slots which is closest to the second end and includes a second hook. The second engaging member is adjacent to the second end and includes a third hook. When the first housing is assembled to the inner slide rail, the first fixing portions push against the first engaging member, the second hook is out of the path of engagement with the first hook, and the first housing and the inner slide rail slide to a position where the third hook is engaged with the first hook. Thus, the slide rail assembly can be adapted to housings of various sizes.

Description

Technical Field

[0001] This disclosure relates to a slide rail integration, and more particularly to a slide rail integration that fits housings of various sizes. Background Technology

[0002] Current slide rail assemblies are single-section slide rail assemblies with a single sliding length. When single-section slide rail assemblies are installed in housings of different sizes, it is necessary to select a single-section slide rail assembly with a corresponding sliding length according to the size of the housing, which leads to an increase in material preparation and storage costs. Summary of the Invention

[0003] The purpose of this disclosure is to provide a slide rail integration that can have different sliding lengths depending on different housing sizes, so as to improve the ease of use of the slide rail integration and reduce costs.

[0004] The slide rail integration disclosed herein is suitable for mounting on a first side of a first housing. The first side of the first housing has a plurality of first fixing portions. The slide rail integration includes an outer slide rail, an inner slide rail, a first engaging assembly, and a second engaging assembly. The outer slide rail includes a first hook. The inner slide rail is slidably mounted on the outer slide rail along a sliding direction and includes a first end, a second end, and a plurality of positioning grooves located between the first end and the second end. These first fixing portions are adapted to engage with corresponding numbers of these positioning grooves to fix the first housing to the inner slide rail. The first engaging assembly is movably mounted on the inner slide rail and partially overlaps a critical positioning groove closest to the second end among these positioning grooves; the first engaging assembly includes a second hook. The second engaging assembly is movably mounted on the inner slide rail and close to the second end; the second engaging assembly includes a third hook. When the first housing assembly is mounted on the inner slide rail, one of the first fixing parts of the first housing pushes against the first engaging component located in the critical positioning groove, causing the second hook to leave the path of engaging with the first hook, and the first housing and the inner slide rail are adapted to slide relative to the outer slide rail to the position where the third hook engages with the first hook.

[0005] According to one embodiment of this disclosure, the length of the first housing in the sliding direction is greater than the distance between the first end and the first engaging component, and less than the distance between the first end and the second engaging component.

[0006] According to one embodiment of this disclosure, the projection of one end of the first housing onto the inner slide rail in the sliding direction is located between the projection of the second hook onto the inner slide rail and the projection of the third hook onto the inner slide rail.

[0007] According to one embodiment of this disclosure, the slide rail is integrated and adapted to be disposed in a second housing. A second side of the second housing is provided with a plurality of second fixing parts. The plurality of second fixing parts are adapted to engage with a plurality of the positioning grooves to fix the second housing to the inner slide rail. When the second housing is fixed to the inner slide rail, the second hook is located on the path of engaging with the first hook. The second housing and the inner slide rail are adapted to slide relative to the outer slide rail to the position where the second hook engages with the first hook.

[0008] According to one embodiment of this disclosure, the length of the second housing in the sliding direction is less than the distance between the first end and the first engaging component.

[0009] According to one embodiment of this disclosure, when the second housing is fixed to the inner slide rail, the first engaging component is pushed to the side, causing the second hook to leave the path of engaging with the first hook, so that the inner slide rail is suitable for disengaging from the outer slide rail.

[0010] According to one embodiment of this disclosure, the first engaging component includes a first body pivotally connected to the inner slide rail, and the second hook is disposed on the first body.

[0011] According to one embodiment of this disclosure, the first engaging assembly further includes a first spring piece adapted to move closer to or away from the inner slide rail. The second hook is disposed on the first spring piece, and the first spring piece includes a first groove corresponding to the critical positioning groove. When the first housing is fixed to the inner slide rail, the first fixing part of the plurality of first fixing parts of the first housing that is located in the critical positioning groove engages with the critical positioning groove and the first groove, causing the first spring piece to move closer to the inner slide rail, thereby causing the second hook to leave the path of engaging with the first hook.

[0012] According to one embodiment of this disclosure, the first spring has a bent portion that bends toward the inner slide rail, the bent portion being located at the opening of the first groove.

[0013] According to one embodiment of this disclosure, during the process of fixing the first housing to the inner slide rail, the part of the first fixing part located in the critical positioning groove enters the critical positioning groove, causing the bent part of the first spring to deform toward the inner slide rail and abut against the inner slide rail, and the second hook leaves the path of engaging with the first hook.

[0014] Based on the above, the slide rail integration of this disclosure, through the critical positioning groove of the inner slide rail and the structural interference between the first engaging component and the first fixing part of the first housing, allows the second hook of the first engaging component to automatically misalign with the first hook, thereby engaging the first hook with the third hook. Therefore, the first housing and the inner slide rail can have a longer sliding stroke. Furthermore, when the slide rail integration is installed on a shorter housing, the second hook aligns with the first hook, causing the first hook to engage with the second hook. In this case, the short housing and the inner slide rail can have a shorter sliding stroke. Thus, the slide rail integration is adaptable to housings of various sizes, and the inner slide rail can have different sliding lengths depending on the different housing sizes, thereby improving the ease of use of the slide rail integration and reducing costs.

[0059] Figure 1 This is a schematic diagram of a slide rail integrated into a chassis according to an embodiment of the present disclosure. Cartesian coordinates XYZ are provided herein for component description. Please refer to... Figure 1 The chassis 400 can accommodate multiple first housings 200 and multiple second housings 300. Each of the two sides of a first housing 200 is provided with a slide rail integration 100a, allowing the first housing 200 to slide into or out of the chassis 400 along a sliding direction (i.e., the X-axis direction). Similarly, each of the two sides of a second housing 300 is provided with a slide rail integration 100a, allowing the second housing 300 to slide relative to the chassis 400. The first housings 200 and second housings 300 are, for example, server housings, but are not limited thereto.

[0060] Figure 2 yes Figure 1 A schematic diagram of the slide rail integration before the first housing is assembled. Figure 3 yes Figure 2 A schematic diagram of the slide rail integration and the first housing assembly. Figure 4 yes Figure 3 The slide rail integration and the first housing are shown in a cross-sectional view along line AA, which is a straight section parallel to the YZ plane. Figure 2 and Figure 3 The outer slide rail 110 is presented in a perspective manner.

[0061] Please also refer to Figures 2 to 4 The slide rail integration 100a includes an outer slide rail 110, an inner slide rail 120, a first engaging assembly 130a, and a second engaging assembly 140a. The outer slide rail 110 can be installed in the chassis 400 ( Figure 1 It includes a first latch 112. The inner slide rail 120 is slidably disposed on the outer slide rail 110 along the sliding direction (X-axis), and includes a first end 122, a second end 124, and a plurality of positioning grooves 126 located between the first end 122 and the second end 124. The first engaging assembly 130a and the second engaging assembly 140a are movably disposed on the inner slide rail 120.

[0062] like Figure 2As shown, the first engaging component 130a of this embodiment includes a first body 131a and a second hook 132a disposed on the first body 131a. The second engaging component 140a includes a second body 141a and a third hook 142a disposed on the second body 141a.

[0063] The first body 131a of the first engaging assembly 130a is pivotally connected to the inner slide rail 120, and the second body 141a of the second engaging assembly 140a is pivotally connected to the inner slide rail 120. The first engaging assembly 130a partially overlaps the positioning groove 126. The second engaging assembly 140a is located near the second end 124.

[0064] A first side 210 of the first housing 200 is provided with a plurality of first fixing parts 220. The length L1 of the first housing 200 in the sliding direction (X-axis) is greater than the distance L2 between the first end 122 and the second hook 132a of the first engaging assembly 130a, and less than the distance L3 between the first end 122 and the third hook 142a of the second engaging assembly 140a. Therefore, when the first housing 200 is assembled on the slide rail assembly 100a, the projection of the end 230 of the first housing 200 in the sliding direction (X-axis) onto the inner slide rail 120 is located between the projection of the first engaging assembly 130a onto the inner slide rail 120 and the projection of the second engaging assembly 140a onto the inner slide rail 120.

[0065] like Figure 3 As shown, when the first housing 200 is fixed to the inner slide rail 120, these first fixing parts 220 can engage with corresponding numbers of these positioning grooves 126 to fix the first housing 200 to the inner slide rail 120. The positioning groove 126 closest to the second end 124 (i.e., the positioning groove 126 that partially overlaps with the first engaging assembly 130a) is a critical positioning groove 128. One of the first fixing parts 220 of the first housing 200 can engage with the critical positioning groove 128.

[0066] Since the first engaging component 130a partially overlaps the critical positioning groove 128, when the first housing 200 is fixed to the inner slide rail 120, the first fixing part 220 located in the critical positioning groove 128 moves into the critical positioning groove 128 and pushes against the first engaging component 130a. The first body 131a of the first engaging component 130a can be pushed against by the first fixing part 220 and pivot relative to the inner slide rail 120 as follows: Figure 3 The location is shown in the enlarged view.

[0067] like Figure 3 As shown in the enlarged view, the second hook 132a is misaligned with the first hook 112 and leaves the path S from which it engages with the first hook 112. Path S is parallel to the sliding direction (X-axis). Figure 4As shown, the second hook 132a is located below the first hook 112 in the Z-axis direction, and the first fixing part 220 does not contact the first hook 112. The third hook 142a of the second engaging assembly 140a is located on the path S that engages with the first hook 112.

[0068] When the first housing 200 and the inner slide rail 120 slide out along the sliding direction (i.e., the +X axis direction), the housing 400 ( Figure 1 And move to such Figure 3 At the indicated position, the second hook 132a is not engaged with the first hook 112. The first housing 200 and the inner slide rail 120 can continue to slide relative to the outer slide rail 110 until the first housing 200 and the inner slide rail 120 slide to the position where the third hook 142a of the second engaging assembly 140a engages with the first hook 112. In this embodiment, the third hook 142a can limit the sliding stroke of the first housing 200 and the inner slide rail 120 along the sliding direction (X-axis). The sliding stroke can be a distance L3.

[0069] Because the length L1 of the first casing 200 is less than the distance L3 ( Figure 3 When the third hook 142a engages with the first hook 112, the first housing 200 can be completely slid out of the chassis 400. Figure 1 This makes it easier to replace or repair.

[0070] When the first housing 200 and the inner slide rail 120 are to be completely removed from the chassis 400 ( Figure 1 When removed from the machine, the second body 141a of the second engaging assembly 140a can be rotated to drive the third hook 142a away from the path S that engages with the first hook 112, so that the inner slide rail 120 can disengage from the outer slide rail 110. The first housing 200 completely disengages from the chassis 400.

[0071] Therefore, it can be seen that through the structural interference between the first fixing part 220 of the first housing 200 and the first engaging component 130a, the first engaging component 130a can be automatically rotated, causing the second hook 132a to be misaligned with the first hook 112. The first engaging component 130a will not affect the sliding of the first housing 200 and the inner slide rail 120. Therefore, the user only needs to push or pull the first housing 200 to slide the first housing 200 into or out of the chassis 400. Figure 1 ).

[0072] Figure 5 yes Figure 1 The diagram shows the slide rail integration and the second housing assembly, with the outer slide rail 110 presented in perspective. Figure 6 yes Figure 5 The slide rail integration and the second housing are shown in a cross-sectional view along line BB, which is a cross-section parallel to the XY plane. Please also refer to... Figure 5 and Figure 6The slide rail integration 100a can also be disposed in the second housing 300. The difference between the second housing 300 and the first housing 200 is that the length L4 of the second housing 300 in the sliding direction (X-axis) is less than the distance L2 between the first end 122 of the inner slide rail 120 and the second hook 132a of the first engaging component 130a.

[0073] In addition, such as Figure 3 and Figure 5 As shown in the enlarged view, the slide rail integration 100a fixed to the second housing 300 and the slide rail integration 100a fixed to the first housing 200 ( Figure 3 The difference lies in Figure 5 In this embodiment, the first engaging component 130a does not pivot relative to the inner slide rail 120, but only partially overlaps the critical positioning groove 128.

[0074] like Figure 5 As shown, when the second housing 300 is fixed to the inner slide rail 120, a plurality of second fixing parts 320 provided on a second side 310 of the second housing 300 can engage with a corresponding number of the positioning grooves 126 of the inner slide rail 120, so that the second housing 300 is fixed to the inner slide rail 120. Since the length L4 of the second housing 300 is relatively short, the second fixing parts 320 will not extend into the critical positioning groove 128, so that the second hook 132a is located on the path S that engages with the first hook 112. Figure 6 ).

[0075] When the second housing 300 slides out along the sliding direction (+X axis direction) of the chassis 400 ( Figure 1 When the second housing 300 and the inner slide rail 120 slide relative to the outer slide rail 110, the second hook 132a of the inner slide rail 120 engages with the first hook 112 of the outer slide rail 110. In this embodiment, the second hook 132a can limit the sliding stroke of the second housing 300 and the inner slide rail 120 along the sliding direction (X-axis). The sliding stroke can be a distance L2.

[0076] Because the length L4 of the second casing 300 is less than the distance L2 ( Figure 5 When the second hook 132a engages with the first hook 112, the second housing 300 can be completely slid out of the chassis 400. Figure 1 This makes it easier to replace or repair.

[0077] When the second housing 300 and the inner slide rail 120 are to be completely removed from the chassis 400 ( Figure 1 When removed from the inner slide rail 120, the first engaging component 130a and the second engaging component 140a can be pushed and pivoted relative to the inner slide rail 120. At this time, the second hook 132a and the third hook 142a leave the path S that engages with the first hook 112, so that the inner slide rail 120 can disengage from the outer slide rail 110.

[0078] Based on the above, the same slide rail integration 100a of this embodiment is applicable to housings of different sizes (e.g., first housing 200 and second housing 300), thereby reducing the material preparation and storage costs of the slide rail integration 100a. Through the provision of the critical positioning groove 128 of the inner slide rail 120 and the first engaging component 130a, when the slide rail integration 100a is installed in a longer housing (e.g., ... Figure 3 When the slide rail integration 100a is on the first housing 200 (as shown), it can cause structural interference with the first housing 200. The user can misalign the second hook 132a with the first hook 112 without manually adjusting the slide rail integration 100a, thus allowing the slide rail integration 100a to have a longer sliding stroke (e.g., ...). Figure 3 The distance L3 shown.

[0079] When the slide rail integrated 100a is set in a shorter housing (e.g.) Figure 5 When the second housing 300 shown is in place, the second latch 132a aligns with the first latch 112, thereby giving the slide rail assembly 100a a shorter sliding stroke (e.g., ...). Figure 5 The distance L2 shown is used. Thus, the slide rail integration 100a can be adapted to housings of various sizes (e.g., first housing 200 and second housing 300) to improve the ease of use of the slide rail integration 100a.

[0080] It is worth mentioning that, such as Figure 1 As shown, in this embodiment, a slide rail integration 100a is provided on each side of the first housing 200 / second housing 300, but this is not a limitation. In an embodiment not shown, the user may provide the slide rail integration 100a only on one side of the first housing 200 / second housing 300, and the other side of the first housing 200 / second housing 300 may be provided with a slide rail that does not have the aforementioned first engaging component and second engaging component. By providing the slide rail integration 100a on only one side, the aforementioned effect of changing the pull-out distance according to different housing lengths can still be achieved.

[0081] Of course, the connection method between the first engaging component and the second engaging component and the inner slide rail 120, as well as the structure of the first engaging component and the second engaging component, are not limited to the foregoing embodiments.

[0082] Figure 7A This is a schematic diagram of the slide rail integration and assembly with the first housing according to another embodiment of the present disclosure. Figure 7B yes Figure 7A A partial enlarged view of the first engagement component. Figure 7A and Figure 7B The outer slide rail 110 is presented in a perspective manner. Figure 8 yes Figure 7A The slide rail integration and the first housing are shown in a cross-sectional view along the CC line, which is a straight section parallel to the YZ plane.

[0083] Please also refer to Figure 3 , Figures 7A to 8 The first engaging component 130b and the second engaging component 140b in this embodiment are similar to those in the previous embodiment, except that... Figures 7A to 8 The first engaging component 130b of the slide rail integration 100b includes a first spring 131b, and the second engaging component 140b includes a second spring 141b. The first engaging component 130b and the second engaging component 140b have similar structures.

[0084] like Figure 7A As shown in the enlarged view, the second spring piece 141b is movable towards or away from the inner slide rail 120, and the third hook 142b is disposed on the second spring piece 141b. The second spring piece 141b includes a second groove 148b and a bent portion 149b located next to the second groove 148b. The bent portion 149b is located at the opening of the second groove 148b. The bent portion 149b is bent towards the inner slide rail 120 (i.e., in the -Y axis direction) at the second bending portion 141b.

[0085] When the slide rail integration 100b is not provided in the housing (first housing 200 or second housing 300), the provision of the bending portion 149b ensures that the second spring piece 141b is spaced a certain distance from the inner slide rail 120 in the Y-axis direction, so that the second latch 132b is positioned on the path S that engages with the first latch 112. In this embodiment, the bending portion 149b does not contact the inner slide rail 120, but it is not limited to this.

[0086] Similarly, the first spring piece 131b is movable towards or away from the inner slide rail 120, and the second hook 132b is disposed on the first spring piece 131b. The first spring piece 131b includes two slots 134b, and the portion of the first spring piece 131b located between the two slots 134b is bent to form the second hook 132b. In other words, the first spring piece 131b and the second hook 132b are integrally formed. The first spring piece 131b includes a first groove 138b corresponding to the critical positioning groove 128 and a bent portion 139b bent toward the inner slide rail 120 (in the Y-axis direction). The bent portion 139b is located at the opening of the first groove 138b.

[0087] like Figure 7A and Figure 7B As shown, when the first housing 200 is mounted on the inner slide rail 120, the first fixing part 220 of the first housing 200, which is located in the critical positioning groove 128, engages with the critical positioning groove 128 and the first groove 138b, causing the first spring piece 131b to move closer to the inner slide rail 120.

[0088] More specifically, such as Figure 7BAs shown, during the process of the first housing 200 being installed in the inner slide rail 120, the first fixing part 220 enters the critical positioning groove 128 from the opening of the critical positioning groove 128. The bent part 139b of the first spring piece 131b is pulled by the first fixing part 220, causing the bent part 139b to deform towards the inner slide rail 120 and abut against the inner slide rail 120. At this time, the second hook 132b leaves the path S that engages with the first hook 112. Figure 8 As shown, the second hook 132b is located to the left of the first hook 112 in the Y-axis direction without contacting the first hook 112, and the third hook 142b is located on the path S that engages with the first hook 112. Figure 8 ).

[0089] Therefore, when the first housing 200 and the inner slide rail 120 slide out of the housing 400 along the sliding direction (+X axis direction) Figure 1 When the second hook 132b slides through the first hook 112, the first hook 112 engages with the third hook 142b.

[0090] When the first housing 200 and the inner slide rail 120 are to be removed from the chassis 400, the second spring piece 141b can be deformed to approach or abut against the inner slide rail 120, until the third latch 142b leaves the path S that engages with the first latch 112. At this time, the inner slide rail 120 can disengage from the outer slide rail 110. The slide rail integration 100b in this embodiment has the same effect as the above embodiment.

[0091] Furthermore, the first spring piece 131b and the second spring piece 141b may also exclude the bent portions 139b and 149b. When assembling the slide rail assembly 100b into the first housing 200, the user can manually press the first spring piece 131b to bring it closer to the inner slide rail 120. The first fixing portion 220 of the first housing 200 enters the critical positioning groove 128 and the first recess 138b to position the first spring piece 131b close to the inner slide rail 120, thereby causing the second latch 132b to leave the path S (where it engages with the first latch 112). Figure 8 ).

[0092] Figure 9 yes Figure 7A The diagram shows the slide rail integration and the second housing assembly, with the outer slide rail 110 presented in perspective. Figure 10 yes Figure 9 The slide rail integration and the second housing are shown in a cross-sectional view along line DD, which is a cross-section parallel to the XY plane. Please also refer to... Figure 9 and Figure 10When the second housing 300 is fixed to the inner slide rail 120, these second fixing parts 320 do not engage with the critical positioning groove 128 and the first groove 138b of the first engaging assembly 130b, so that the second hook 132b is still located on the path S that engages with the first hook 112. Figure 10 ).

[0093] When the second housing 300 and the inner slide rail 120 slide out along the sliding direction (+X axis direction) of the chassis 400 ( Figure 1 When the second latch 132b engages with the first latch 112, the second housing 300 and the inner slide rail 120 are removed from the chassis 400. Figure 1 When removed from the inner slide rail 120, the first spring piece 131b and the second spring piece 141b can be deformed to approach or abut against the inner slide rail 120, thereby causing the second hook 132b and the third hook 142b to leave the path S (where they engage with the first hook 112) Figure 10 At this point, the inner slide rail 120 can disengage from the outer slide rail 110.

[0094] In summary, the slide rail integration of this disclosure, through the critical positioning groove of the inner slide rail and the structural interference between the first engaging component and the first fixing part of the first housing, allows the second hook of the first engaging component to automatically misalign with the first hook, thereby engaging the first hook with the third hook. The first housing and the inner slide rail can have a relatively long sliding stroke. Furthermore, when the slide rail integration is installed on a shorter housing (e.g., a second housing), the second hook does not misalign with the first hook, allowing the first hook to engage with the second hook. In this case, the second housing and the inner slide rail can have a shorter sliding stroke. Therefore, the slide rail integration is adaptable to housings of various sizes, and the inner slide rail can have different sliding lengths depending on the different housing sizes, thereby improving the ease of use of the slide rail integration and reducing costs.

A plurality of first fixing parts are adapted to engage with corresponding numbers of the plurality of positioning grooves, so that the first housing is fixed to the inner slide rail; and A first engaging component is movably disposed on the inner slide rail and partially overlaps with a critical positioning groove closest to the second end among the plurality of positioning grooves. The first engaging component includes a second hook. A second engaging component is movably disposed on the inner slide rail and close to the second end. The second engaging component includes a third hook. When the first housing assembly is mounted on the inner slide rail, one of the plurality of first fixing parts of the first housing pushes against the first engaging component located in the critical positioning groove, thereby causing the second hook to leave the path of engaging with the first hook, and the first housing and the inner slide rail are adapted to slide relative to the outer slide rail to the position where the third hook engages with the first hook.

2. The slide rail integration as described in claim 1, characterized in that, The length of the first housing in the sliding direction is greater than the distance between the first end and the first engaging component, and less than the distance between the first end and the second engaging component.

3. The slide rail integration as described in claim 1, characterized in that, The projection of one end of the first housing onto the inner slide rail in the sliding direction is located between the projections of the second hook onto the inner slide rail and the projections of the third hook onto the inner slide rail.

4. The slide rail integration as described in claim 1, characterized in that, The slide rail is integrated and adapted to be disposed in a second housing. A second side of the second housing is provided with a plurality of second fixing parts. The plurality of second fixing parts are adapted to engage with a plurality of the positioning grooves so that the second housing is fixed to the inner slide rail. When the second housing is fixed to the inner slide rail, the second hook is located on the path of engaging with the first hook. The second housing and the inner slide rail are adapted to slide relative to the outer slide rail until the position where the second hook engages with the first hook.

5. The slide rail integration as described in claim 4, characterized in that, The length of the second housing in the sliding direction is less than the distance between the first end and the first engaging assembly.

6. The slide rail integration as described in claim 4, characterized in that, When the second housing is fixed to the inner slide rail, the first engaging component is pushed to the side, causing the second hook to leave the path of engaging with the first hook, so that the inner slide rail is suitable for disengaging from the outer slide rail.

7. The slide rail integration as described in claim 1, characterized in that, The first engaging component includes a first body pivotally connected to the inner slide rail, and the second hook is disposed on the first body.
