Description

Technical Field

[0001] This utility model relates to a slide rail assembly, particularly to a cabinet adapted to an industrial server. The assembly is installed in the chassis of the industrial server via a slide rail. When the slide rail is locked in the extended position relative to another slide rail, one end of the guide is connected to the operating mechanism, and the other end of the guide is spaced from the locking mechanism. The guide exerts force on the operating mechanism and the locking mechanism respectively, thereby releasing the slide rail relative to the other slide rail so that it can be retracted, displaced, and disassembled. Background Technology

[0002] In the prior art, the cabinet for placing server-related electronic equipment has layers of removable chassis inside. A slide rail assembly is provided between the chassis and the cabinet to guide the chassis to slide out and into the cabinet. The slide rail assembly consists of a first rail (such as an inner frame), a second rail (such as a middle frame) that slides relative to the first rail, and a third rail (such as an outer frame) that slides relative to the second rail. The outer frame is fixed to the inner side of the cabinet, and the inner frame is installed on the side of the chassis. The middle frame and the inner frame slide on the connected outer frame, so that the chassis can slide out or into the cabinet smoothly.

[0003] When the chassis slides out of the rack, that is, when the inner frame extends relative to the middle frame to the end of its travel, the conventional installation method involves a locking mechanism and an operating mechanism that are movably installed on one side of the inner frame. The locking mechanism detaches the inner frame from the middle frame, and the operating mechanism detaches or retracts the inner frame into the middle frame. However, when force is applied to the operating mechanism (such as the operating handle), there is a situation where the inner frame cannot immediately detach or retract into the middle frame during the empty travel. This can cause the user to apply excessive force to the operating mechanism (such as the operating handle), resulting in impacts to the frame or corresponding components. This can easily damage the components of the operating mechanism and generate impact noise. Furthermore, because there is no foolproof design, accidental activation of the operating mechanism can trigger the locking mechanism, causing the inner frame to accidentally fall off, damaging the electronic devices inside the chassis. Therefore, how to prevent the inner frame from accidentally falling off and the empty travel of the operating mechanism is a direction that relevant industry players urgently need to research and improve.

[0004] However, when adding new functional components to the slide rail, it is often necessary to avoid locking mechanisms and operating parts. Furthermore, the dimensions of the slide rails and their internal components vary depending on the different chassis specifications (lengths). For example, locking mechanisms are typically made of high-priced stainless steel or galvanized steel. Changing the dimensions (length) requires additional stamping and molding. A stainless steel lever inside the locking mechanism usually extends from one end of the slide rail to the other, increasing costs and causing the component to occupy a large portion of the frame space. In addition, increasing the lever size significantly increases material costs. Therefore, how to solve the problems of increased costs and insufficient frame space is a direction that industry players urgently need to research and improve. Summary of the Invention

[0005] This utility model relates to a slide rail assembly, comprising: a first rail and a second rail that are displaced relative to the first rail; an operating mechanism having a first operating member pivotally connected to one end of the first rail, the first operating member being connected to one end of a linkage member, the operating mechanism being movable relative to the first rail; and a locking mechanism that is movable relative to the first rail, locking the first rail relative to the second rail in an extended position, with the other end of the linkage member positioned opposite the locking mechanism and having a distance between the other end of the linkage member and the locking mechanism; thereby, when the first operating member is subjected to force and generates a first stage of pivoting, the other end of the linkage member moves in a first direction to abut against the locking mechanism, and when the first operating member continues to be subjected to force in the same direction and generates a second stage of pivoting, the other end of the linkage member drives the locking mechanism to displace and release it from the extended position, then the first rail displaces and retracts to the second rail.

[0006] Preferably, the locking mechanism is subjected to force in a second direction opposite to the first direction, which is through the gap to allow the locking mechanism to move, and the locking mechanism does not drive the other end of the linkage of the operating mechanism to release the first rail to the extended position, so that the first rail is displaced from the second rail.

[0007] Preferably, the locking mechanism has a positioning member that abuts against the other end of the linkage, and the other end of the linkage extends with a supporting portion that corresponds to the positioning member, and there is a gap between the positioning member and the supporting portion.

[0008] Preferably, the first rail extends inward from the outer side by a bend, and the operating mechanism has a first elastic member located on one side of the first rail. One end of the first elastic member is disposed on the first operating member, and the other end of the first elastic member abuts against the at least one bend. When the first operating member pivots, the first operating member presses and deforms the first elastic member. When the first operating member stops pivoting, the first elastic member resets to drive the first operating member to pivot and reset.

[0009] Preferably, the operating mechanism has a limiting member, and the first operating member has a longitudinal wall, one side of which is bent and extended to form a side wall. A limiting hole is formed in a portion of the longitudinal wall and the side wall, and one end of the first elastic member is engaged in the limiting hole. The limiting member passes through the limiting hole and is then connected to the first rail to prevent the first operating member from swaying relative to one side of the first rail. When the first operating member pivots and resets, the two ends of the limiting hole abut against the limiting member to limit the first operating member.

[0010] Preferably, the locking mechanism has a second operating member, a first left stop, a first right stop, a second elastic member, and a positioning member. The first left stop and the first right stop are movably disposed on one side of the first rail, and the two ends of the second elastic member are respectively connected to the first left stop and the first right stop. The second operating member is movably disposed on one side of the first rail and abuts against the first left stop and the first right stop. The positioning member is disposed at one end of the second operating member adjacent to the first operating member, and a first stop is disposed at one end of the second rail.

[0011] Preferably, when the second operating member is subjected to force, it moves in the first direction, causing the first left stop to move. The first left stop, in turn, causes the second elastic member to deform elastically, thereby disengaging the first left stop from one end of the first stop. When the second operating member stops being subjected to force, the second elastic member elastically returns to its original position, causing the first left stop to abut against one end of the first stop. The first left stop then causes the second operating member to return to its original position.

[0012] Preferably, when the second operating member is subjected to force, it moves in the second direction, and the second operating member drives the first right stop to move. The first right stop is linked to the second elastic member to deform elastically, so that the first right stop is disengaged from the other end of the first stop. When the second operating member stops being subjected to force, the second elastic member elastically returns to its original position. The second elastic member is linked to the first right stop to abut against the other end of the first stop, and the first right stop drives the second operating member to return to its original position.

[0013] Preferably, the abutting part and the positioning member are a mating abutting structure.

[0014] Preferably, the second operating member has a stop portion that bends and extends to the middle of the second operating member, the first left stop member has a first stop portion protruding at one end, and the first right stop member has a second stop portion protruding at the other end away from the first stop portion, and the two ends of the stop portion respectively abut against the first stop portion and the second stop portion.

[0067] Example

[0068] Please see Figure 1 and Figure 2 As shown, this utility model is a slide rail assembly 1, comprising: a first rail 11, a second rail 12, a third rail 13, an operating mechanism 14, and a locking mechanism 15. The first rail 11 extends inward from the outer side by a bent portion 111, and the first rail 11 is displaced relative to the third rail 13. The second rail 12 is used to extend the displacement stroke of the first rail 11 relative to the third rail 13. One end of the second rail 12 has a first stop 121. One end of the third rail 13 has an integrally formed first stop portion 131 (e.g., formed by stamping). The operating mechanism 14 has a first operating member 141, a linkage member 142, a limiting member 143, and a first elastic member. 144, the first operating member 141 is pivotally connected to one end of the first rail 11, one end of the linkage member 142 is disposed on the first operating member 141, the other end of the linkage member 142 has a distance H from the locking mechanism 15, the other end of the linkage member 142 bends and extends to have a supporting portion 1421, the first elastic member 144 is located on one side of the first rail 11, one end of the first elastic member 144 is disposed on the first operating member 141, and the other end of the first elastic member 144 abuts against the at least one bent portion 111. The structure, displacement, unfolding and retraction of the first rail 11, the second rail 12 and the third rail 13 are already known technologies, and will not be described in detail here for the sake of simplicity.

[0069] Please see Figure 3 As shown, the first operating member 141 has a longitudinal wall 1414, and a locking portion 1411 is bent and extended on one side of the longitudinal wall 1414. A side wall 1412 is bent and extended on the other side of the longitudinal wall 1414 opposite to the locking portion 1411. A limiting hole 1413 is formed in a portion of the longitudinal wall 1414 and a portion of the side wall 1412. One end of the first elastic member 144 is engaged in the limiting hole 1413, and the other end of the first elastic member 144 abuts against a bent portion 111 of the first rail 11, and then extends and bends continuously to abut against another bent portion 111. The limiting member 143 (e.g., a height equalizing screw) passes through the limiting hole 1413 and is then assembled onto the first rail 11.

[0070] Please refer to the following: Figure 3As shown, the locking mechanism 15 includes a second operating member 151, a first left stop 152, a first right stop 153, a second elastic member 154, and a positioning member 155. The second operating member 151 is movably disposed on one side of the first rail 11 and has a stop portion 1511 that bends and extends at the middle of the second operating member 151. The first left stop 152 and the first right stop 153 are movably disposed opposite to each other on one side of the first rail 11. One end of the first left stop 152 has a protruding first stop portion 1521, and the first right stop 153 is located away from the first stop portion 152. 1. A second stop portion 1531 is provided at the other end. The two ends of the stop portion 1511 of the second operating member 151 abut against the first stop portion 1521 of the first left stop member 152 and the second stop portion 1531 of the first right stop member 153, respectively. The two ends of the second elastic member 154 are connected to the first left stop member 152 and the first right stop member 153, respectively. The positioning member 155 holds against the other end of the linkage member 142. The abutting portion 1421 corresponds to the positioning member 155. The positioning member 155 and the abutting portion 1421 have the distance H between them. The abutting portion 1421 and the positioning member 155 are a mutually matching abutting structure.

[0071] Please see Figures 4 to 9 As shown, when the first operating member 141 is pivoted under force, the limiting hole 1413 of the first operating member 141 presses against one end of the first elastic member 144, causing elastic deformation. The locking portion 1411 of the first operating member 141 disengages from the first stop portion 131 of the third rail 13. When the first operating member 141 is subjected to force in a first direction D1, the first operating member 141 drives the first rail 11 to move relative to the third rail 13 in the first direction D1, causing the first rail 11 to leave the retracted position P1. The locking portion 1411 of the first operating member 141 passes over the first stop portion 131 of the third rail 13. When the first operating member 141 stops pivoting under force, one end of the first elastic member 144 elastically resets. One end of the first elastic member 144 abuts against the limiting hole 1413 to drive the first operating member 141 to pivot and reset.

[0072] Please see Figures 10 to 11As shown, when the first rail 11 moves relative to the second rail 12 in the first direction D1, the side of the first right stop 153 away from the second stop 1531 abuts against one end of the first stop 121, causing the second elastic member 154 to elastically deform. The first right stop 153 moves to one side of the first rail 11. At this time, the first rail 11 continues to move relative to the second rail 12 in the second direction D2. The first right stop 153 passes the first stop 121, and the second elastic member 154 elastically resets, causing the first right stop 153 to move and reset. Then the first left stop 152 abuts against one end of the first stop 121, and the first right stop 153 abuts against the other end of the first stop 121, so that the first rail 11 is locked relative to the second rail 12 in an extended position P2.

[0073] Please see Figures 11 to 15 As shown, the operating mechanism 14 moves relative to the first rail 11. When the first operating member 141 is subjected to force and generates a first segment L1 pivot, the limiting member 143 disengages from one end of the limiting hole 1413, and the other end of the limiting hole 1413 presses against one end of the first elastic member 144, causing elastic deformation. The first operating member 141 then drives one end of the connecting member 142, and the abutting portion 1421 at the other end of the connecting member 142 moves toward the first direction D1 to abut against the positioning member 155 of the locking mechanism 15. 141 continues to be subjected to force in the same direction, generating a second segment L2 pivot. The abutment portion 1421 at the other end of the linkage 142 drives the positioning member 155 of the locking mechanism 15 to displace in the first direction D1. At this time, the other end of the stop portion 1511 of the second operating member 151 abuts against and pushes the second stop portion 1531 of the first right stop member 153 to displace. The first right stop member 153 is linked to the second elastic member 154 to elastically deform, causing the first right stop member 153 to rotate and move in conjunction with the other end of the first stop member 121. When the first operating member 141 disengages, and the limiting member 143 abuts against the other end of the limiting hole 1413, it stops the first operating member 141 from continuing to pivot. The limiting member 143 also prevents the first operating member 141 from swaying relative to the first rail 11. At this time, the first rail 11 is released from the extended position P2 relative to the second rail 12, and the first rail 11 can then be displaced relative to the second rail 12 in the second direction D2, so that the first rail 11 is displaced and retracted into the second rail 12. When the force application and pivoting stops at 141, the stop portion 1511 of the second operating member 151 of the locking mechanism 15 is reset, the second elastic member 154 of the locking mechanism 15 is reset, and the other end of the stop portion 1511 of the second operating member 151 abuts against the second stop portion 1531 of the first right stop member 153, so as to drive the first right stop member 153 to move against the other end of the first stop member 121 of the second rail 12. The direction of operation of the first operating member 141 is opposite to that described above, and will not be repeated here.

[0074] Please refer to the following: Figure 10 , Figures 15 to 17 As shown, the locking mechanism 15 moves relative to the first rail 11. When the second operating member 151 of the locking mechanism 15 is subjected to force and moves in the second direction D2 opposite to the first direction D1, the other end of the linkage 142 has a distance H with the locking mechanism 15 to allow the locking mechanism 15 to move. The second operating member 151 of the locking mechanism 15 moves in the second direction D2, and the positioning member 155 located at one end of the second operating member 151 of the locking mechanism 15 does not drive the abutment portion 1421 of the other end of the linkage 142 of the operating mechanism 14 which is bent and extended. Moreover, one end of the stop portion 1511 of the second operating member 151 abuts against and pushes the first stop portion 1521 of the first left stop member 152 to displace. The left stop 152 is linked to the second elastic member 154, which is elastically deformed, causing the first left stop 152 to rotate and disengage from one end of the first stop 121. At this time, the first rail 11 is released from the extended position P2 relative to the second rail 12, allowing the first rail 11 to displace in the first direction D1 and disengage from the second rail 12, thus removing the first rail 11 from the second rail 12. When the second operating member 151 of the locking mechanism 15 stops being stressed, the second elastic member 154 of the locking mechanism 15 elastically resets, and one end of the stop portion 1511 of the second operating member 151 abuts against and pushes the first stop portion 1521 of the first left stop 152, thereby causing the first left stop 152 to move against the other end of the first stop 121 of the second rail 12.

[0075] In view of this, the slide rail assembly 1 disclosed in this utility model has a supporting part 1421 extending from the other end of the linkage 142 of the operating mechanism 14 on the first rail 11, which has a distance H between it and the locking mechanism 15. This allows the user to intuitively operate the operating mechanism 14 and the locking mechanism 15 respectively. This helps the user to intuitively apply force to the operating mechanism 14 to close the first rail 11 relative to the second rail 12, and intuitively apply force to the locking mechanism 15 to disengage the first rail 11 relative to the second rail 12. This prevents the user from accidentally touching the operating mechanism 14 and causing the first rail 11 to fall off unexpectedly. When force is applied to the operating mechanism 14, and the first operating member 141 pivots in the first segment L1, the first operating member 141 immediately presses and deforms the first elastic member 144, so that there is a continuous elastic force transmission during the user's operation, so that the user does not apply excessive force to the operating mechanism 14 and can adapt to the idle stroke.

[0076] The slide rail assembly 1 disclosed in this utility model has a distance H between the other end of the linkage 142 of the operating mechanism 14 and the locking mechanism 15. When adapting to different chassis specifications (lengths), only the specifications (lengths) of the first rail 11 and the specifications (lengths) of the operating mechanism 14 need to be changed, without the need to re-stamp and open molds the locking mechanism 15, which is made of stainless steel or galvanized material and has higher costs. For example, the second operating member 151 of the locking mechanism 15 does not need to extend from one end of the first rail 11 to the other end of the first rail 11 and occupy the space on one side of the first rail 11. This helps to reduce stamping and mold opening and material costs, as well as simplify the space on one side of the first rail 11.

The slide rail assembly as claimed in claim 7, wherein, When the second operating member (151) is forced to move in the first direction (D1), the second operating member (151) drives the first left blocking member (152) to move, and the first left blocking member (152) drives the second elastic member (154) to elastically deform, so that the first left blocking member (152) and one end of the first blocking member (121) are separated from each other, and when the second operating member (151) stops being forced, the second elastic member (154) elastically resets, and the second elastic member (154) drives the first left blocking member (152) and one end of the first blocking member (121) to abut against each other, and the first left blocking member (152) drives the second operating member (151) to reset.

9. The slide rail assembly as claimed in claim 7, wherein, The second operating member (151) has a stop portion (1511) extending from one end of the second operating member (151), one end of the first left blocking member (152) protrudes a first stop portion (1521), the other end of the first right blocking member (153) away from the first stop portion (1521) protrudes a second stop portion (1531), and the two ends of the stop portion (1511) abut against the first stop portion (1521) and the second stop portion (1531) respectively.

10. The slide rail assembly as claimed in claim 7, wherein, When the second operating member (151) is forced to move in the second direction (D2), the second operating member (151) drives the first right blocking member (153) to move, the first right blocking member (153) drives the second elastic member (154) to elastically deform, and the first right blocking member (153) is separated from the other end of the first blocking member (121). When the force on the second operating member (151) is removed, the second elastic member (154) elastically returns, the second elastic member (154) drives the first right blocking member (153) to abut against the other end of the first blocking member (121), and the first right blocking member (153) drives the second operating member (151) to return.
