SLIDE RAIL STRUCTURE

1. FIELD OF THE INVENTION

[0001]The present invention relates to a type of slide rail assembly, particularly one suitable for installation and connection to a server rack or furniture, such that one slide rail assembly can be pulled out while another slide rail assembly is locked in place.

2. DESCRIPTION OF THE RELATED ART

[0002]With the mature development of the computer industry and cloud technology, the demand for electronic data access is increasing, especially in artificial intelligence (AI), such as ChatGPT. To meet the demands of high-volume information access, modern server equipment is structured with multiple server chassis housed within a single server rack. The server chassis and server rack are connected using sliding rail assemblies. For example, a first slide rail is provided on each side of the server chassis, and a second slide rail is provided on each side of the server rack, which is opposite to the first slide rail, so that the first slide rail can be displaced on the second slide rail.

SUMMARY OF THE INVENTION

[0003]The main object of the present invention is to provide a slide rail structure in which, when the guide portion moves on the guide track, the stop member, in conjunction with the sliding member, generates frictional positioning on the side of the first slide rail, thereby improving the stability of the guide portion on the guide track or enhancing the stability of the stop member in conjunction with the lock.

[0004]Another object of this invention is to provide a slide rail structure whose protrusion leads to the first positioning hole or the second positioning hole, thereby reliably switching the guide portion positioning, or switching the stop member interlocking the lock.

[0005]Still another object of this invention is to provide a slide rail structure in which the protrusion is located on a spring arm to elastically engage with the first or second positioning hole, thereby improving the effectiveness of preventing engagement failure or damage to the sliding member.

[0006]Still another object of this invention is to provide a slide rail structure in which the structure of the guide rail member forms a guide track and a blocking surface, so that the guide portion can be guided to the guide track or the blocking surface, thereby improving the effect of one slide rail assembly being able to be pulled out and the other slide rail assembly being locked.

[0007]To achieve the above objects, the present invention employs a slide rail structure technique comprising: a first slide rail assembly. The first slide rail assembly comprises at least one first slide rail; a second slide rail movable relative to the at least one first slide rail of the first slide rail assembly; a sliding member located on one side of the at least one first slide rail of the first slide rail assembly, and slidable relative to the side of the at least on first slide rail of the first slide rail assembly; a stop member with a guide portion located on the sliding member of the first slide rail assembly; and a guide rail member with a guide trac located on the second slide rail of the first slide rail assembly. The guide portion of the first slide rail assembly is movable along the guide track of the first slide rail assembly, so that when the guide portion of the first slide rail assembly moves to a first position of the guide track of the first slide rail assembly, the stop member of the first slide rail assembly, in conjunction with the sliding member of the first slide rail assembly, performs a first sliding state; or when the guide portion of the first slide rail assembly moves to a second position of the guide track of the first slide rail assembly, the stop member of the first slide rail assembly, in conjunction with the sliding member of the first slide rail assembly, enters a second sliding state.

[0008]To achieve the above objects, the present invention employs another slide rail structure technique comprising: a first slide rail assembly and a second slide rail assembly, each of the first slide rail assembly and the second slide rail assembly comprising at least one first slide rail and one second slide rail, wherein the second slide rail is movable relative to the first slide rail. The first slide rail assembly and the second slide rail assembly each comprise a sliding member located on the side of the first slide rail; a stop member set on the sliding member and comprising a guide portion; a guide rail member set on the second slide rail and comprising a guide track; and a lock. The lock is equipped with the stop member of the first slide rail assembly and the stop member of the second slide rail assembly. When the second slide rail of the first slide rail assembly moves within the first slide rail of the first slide rail assembly, the guide portion of the first slide rail assembly moves within the guide track of the first slide rail assembly, causing the sliding member of the first slide rail assembly to slide. Next, the stop member of the first slide rail assembly is linked to the lock, which in turn is linked to the stop member of the second slide rail assembly, causing the sliding member of the second slide rail assembly to slide. The guide rail member of the second slide rail assembly prevents the guide portion of the second slide rail assembly from entering the guide track of the second slide rail assembly, thus preventing the second slide rail of the second slide rail assembly from moving within the first slide rail of the second slide rail assembly.

[0009]By employing the aforementioned technical means, the sliding member is located on the side of the first slide rail, integrating the stop member and the guide rail member, and strengthening the structural relationship between the sliding member and the side of the first slide rail. This also effectively stabilizes positioning, ensures reliable switching, prevents failure and damage, and can be effectively applied to the lock and multiple slide rail assemblies.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0021]Please refer to FIGS. 1 to 11. This invention is a slide rail structure, comprising: a first slide rail assembly 100, a sliding member 130, a stop member 140, and a guide rail member 150. The first slide rail assembly 100 comprises at least one first slide rail 110 and one second slide rail 120. The second slide rail 120 moves relative to the first slide rail 110. In this embodiment, the first slide rail 110 is a reinforcing frame and the second slide rail 120 is a middle frame, but it is not limited to this.

[0022]The sliding member 130 is located on the side of the first slide rail 110, and the sliding member 130 slides relative to the side of the first slide rail 110. In this embodiment, the first slide rail 110 is provided with a first positioning hole 111 and a second positioning hole 112, and the sliding member 130 has a protrusion 131 facing the side of the first slide rail 110. When the sliding member 130 reaches a first sliding state S1, the protrusion 131 moves to the first positioning hole 111; or when the sliding member 130 reaches a second sliding state S2, the protrusion 131 moves to the second positioning hole 112. A spring arm 132 is provided in conjunction with the sliding member 130, and the protrusion 131 is located in the spring arm 132, with the sliding member 130 being a single integrally formed plate. The sliding member 130 may also have at least one sliding hole 134, and at least one fastener FT passing through the sliding hole 134 to the first slide rail 110, but is not limited thereto.

[0023]The stop member 140 is disposed on the sliding member 130, and the stop member 140 has a guide portion 141. In this embodiment, the sliding member 130 has a first mounting hole 133, and the stop member 140 has a groove 142, so that the stop member 140 forms a first stop 143 and a second stop 144. Furthermore, the guide portion 141 is located on the end face of the second stop 144, and the second stop 144 is installed in the first mounting hole 133. The first slide rail 110 comprises a first guide hole 113 and a second guide hole 114 extending from the first guide hole 113. Furthermore, the first stop 143 passes through the first guide hole 113 and is spanned by the groove 142 across the second guide hole 114, as shown in FIGS. 3 and 4, but is not limited to this. Furthermore, in this embodiment, the first mounting hole 133 is located at the center of the sliding member 130, and the first mounting hole 133 is a central circular through hole, and the groove 142 is annular, but it is not limited to this.

[0024]The guide rail member 150 is disposed on the second slide rail 120, and the guide rail member 150 has a guide track 151, on which the guide portion 141 moves. In this embodiment, the guide rail member 150 has a first guide block 152 and a second guide block 153, and the guide track 151 is formed by the first guide block 152 and the second guide block 153. To further explain, the first guide block 152 and the second guide block 153 can be a single element with at least one fastener FT passing through the guide rail member 150 to the second slide rail 120. Alternatively, the first guide block 152 and the second guide block 153 may be integrally formed on the second slide rail 120. When the guide portion 141 is stationary in front of the first position P1 of the guide track 151, the guide portion 141 is guided to the side of the first guide block 152, and the side of the first guide block 152 forms a blocking surface B. The blocking surface B obstructs the guide portion 141, preventing the second slide rail 120 from moving within the first slide rail 110, but is not limited to this.

[0025]To further explain, the first position P1 of the guide track 151 is relatively higher than the second position P2 of the guide track 151. As shown in FIGS. 6 and 11, when the guide portion 141 moves to the first position P1 of the guide track 151, the stop member 140, in conjunction with the sliding member 130, performs the first sliding state S1, coordinating with the protrusion 131 to the first positioning hole 111. As shown in FIG. 10, when the guide portion 141 moves between the first position P1 and the second position P2 of the guide track 151, the protrusion 131 is positioned between the first positioning hole 111 and the second positioning hole 112. As shown in FIGS. 8 and 9, when the guide portion 141 moves to the second position P2 of the guide track 151, the stop member 140 is linked to the sliding member 130 to perform the second sliding state S2, which is coordinated with the protrusion 131 to the second positioning hole 112.

[0026]To further explain, the first slide rail assembly 100 further comprises a third slide rail 160, which is located between the first slide rail 110 and the second slide rail 120. The third slide rail 160 is an outer frame fixed to the first slide rail 110, and the second slide rail 120 is movably connected to the third slide rail 160. The third slide rail 160 has an opening 161 corresponding to the first guide hole 113 and the second guide hole 114. Furthermore, in this embodiment, the positions of the first positioning hole 111, the second positioning hole 112, the first guide hole 113, and the second guide hole 114 are sequentially arranged from top to bottom. The combination of the first guide hole 113 being circular and the second guide hole 114 being elongated forms a key shape. The first guide hole 113 is located above the second guide hole 114, but is not limited to this.

[0027]To further explain, the first slide rail assembly 100 further comprises a fourth slide rail 170, which is an inner frame movably connected to the third slide rail 160. The fourth slide rail 170 is typically connected to a load bearing (not shown in the figures), which can be a server chassis or a drawer. It may also comprise a lock 200 on which the stop member 140 is mounted, the stop member 140 being linked to the lock 200. The lock 200 has a second mounting hole 210, and the stop member 140 passes through the second mounting hole 210, and the second stop 144 is located in the second mounting hole 210.

[0028]To further explain, the slide rail structure further comprises a second slide rail assembly 100A. The second slide rail assembly 100A has the same components as the first slide rail assembly 100, which will not be described in detail. Next, the operating mechanisms of the first slide rail assembly 100 and the second slide rail assembly 100A will be explained in detail, with the operating mechanisms for pulling out the slide rails and returning to the slide rails explained in sequence.

[0029]The following explains the operating mechanism of pulling out the slide rail assembly. When the load bearing is pulled out and moved from the server rack or furniture, the fourth slide rail 170 of the first slide rail assembly 100 will also be pulled out along with the load bearing. Furthermore, when the fourth slide rail 170 of the first slide rail assembly 100 is moved under tension, then, as shown in FIGS. 6, 7, 8, and 9, the displacement of the second slide rail 120 of the first slide rail assembly 100 is the main technical feature of this invention, which is located in the stop member 140 of the first slide rail assembly 100 and the stop member 140 of the second slide rail assembly 100A. When the second slide rail 120 of the first slide rail assembly 100 moves relative to the first slide rail 110 of the first slide rail assembly 100, the guide portion 141 of the first slide rail assembly 100 will move relative to the first position P1 of the guide track 151 of the first slide rail assembly 100 to the second position P2 of the guide track 151 of the first slide rail assembly 100. At the same time, the sliding member 130 of the first slide rail assembly 100 will relatively move downwards, causing the protrusion 131 of the first slide rail assembly 100 to move downwards from the first positioning hole 111 of the first slide rail assembly 100 to the second positioning hole 112 of the first slide rail assembly 100. At the same time, the sliding member 130 of the first slide rail assembly 100 will relatively move downwards, thereby completing the pulling-out action of the first slide rail assembly 100.

[0030]Next, the stop member 140 of the first slide rail assembly 100 is linked to the lock 200, and the lock 200 is linked to the stop member 140 of the second slide rail assembly 100A, causing the sliding member 130 of the second slide rail assembly 100A to slide, and the guide rail member 150 of the second slide rail assembly 100A prevents the guide portion 141 of the second slide rail assembly 100A from entering the guide track 151 of the second slide rail assembly 100A, thus preventing the second slide rail 120 of the second slide rail assembly 100A from moving within the first slide rail 110 of the second slide rail assembly 100A.

[0031]The following explains the operating mechanism of returning the slide rail assembly. Once the load bearing returns to its original position, it needs to be pushed back into the server rack or furniture. Furthermore, when the fourth slide rail 170 of the first slide rail assembly 100 moves under thrust, as shown in FIGS. 10 and 11, the displacement of the second slide rail 120 of the first slide rail assembly 100 is the key technical feature that enables this invention. The guide portion 141 of the first slide rail assembly 100 will move relative to the second position P2 of the guide track 151 to the first position P1 of the guide track 151 of the first slide rail assembly 100. At the same time, the sliding member 130 of the first slide rail assembly 100 will move upward relative to the first slide rail assembly 100, so that the protrusion 131 of the first slide rail assembly 100 moves upward from the second positioning hole 112 of the first slide rail assembly 100 to the first positioning hole 111 of the first slide rail assembly 100. At the same time, the sliding member 130 of the first slide rail assembly 100 will relatively move upwards, thereby completing the return motion of the first slide rail assembly 100.

[0032]Therefore, the first slide rail assembly 100 and the second slide rail assembly 100A are connected to each other by the lock 200, and the first slide rail assembly 100 and the second slide rail assembly 100A are externally connected to a frame 300 or other mechanisms, wherein the frame 300 is adapted to be fixed to a server rack or furniture. The second slide rail assembly 100A connected to lock 200 will not move, thus preventing it from being pulled out and ensuring it does not affect the server chassis or furniture drawers below. Therefore, pulling out or pushing back a specific server chassis or furniture drawer will not affect other server chassis or furniture drawers.
