The second rail can move relative to the first rail; the third rail is arranged between the first rail and the second rail; the at least one support structure arrangement is located at a position relative to the first rail; when the second rail is at a predetermined position relative to the first rail, the third rail is used for supporting one part of the second rail, and the at least one supporting structure is used for supporting the other part of the second rail.
Description
Technical Field
The present invention relates to a slide rail assembly, and more particularly, to a slide rail assembly having a supporting mechanism capable of supporting a slide rail with a supporting strength.
Background
As shown in fig. 1, in a rack system, a slide assembly 100 may be mounted to a first column 108 and a second column 110 of a rack 106 via a first bracket 102 and a second bracket 104. Specifically, the slide assembly 100 generally includes a plurality of slides, such as a first rail 112, a second rail 114, and a third rail 116. Wherein the first rail 112 is mounted to the first column 108 and the second column 110 via the first bracket 102 and the second bracket 104; the third rail 116 is movably mounted between the first rail 112 and the second rail 114; the second rail 114 is generally used for mounting a carrier, such as a chassis (chassis).
In the prior art, in order to accommodate more electronic components or devices, the width of the carrier tends to become wider, and under such a situation, how to prevent the slide rail from occupying the installation space of the carrier becomes a non-negligible issue. One of the current practices is to prevent the first rail 112 from occupying the space for mounting the load by allowing the first rail 112 to be mounted into the space between the first column 108 and the second column 110 through the first bracket 102 and the second bracket 104. However, according to this configuration, a problem inevitably arises in that: when the second rail 114 is at a position relative to the first rail 112, although one segment S1 of the second rail 114 can be supported by the third rail 116, the other segments S2 of the second rail 114 cannot be sufficiently supported. For example, a gap G is formed between the second rail 114 and the first rail 112, so that the other rail segment S2 of the second rail 114 cannot be sufficiently supported.
As shown in fig. 2, when the other rail segment S2 of the second rail 114 cannot be sufficiently supported, if the second rail 114 carries a load, the other rail segment S2 of the second rail 114 may be easily bent or deformed by the weight F of the load, so that the mass of the slide rail assembly 100 is affected.

Further, each slide rail assembly 16 of the first embodiment of the present invention is mounted to the first post 12a and the second post 12b through a first bracket 18 and a second bracket 20.
As shown in fig. 4 and 5, the slide rail assembly 16 includes a first rail 22, a second rail 24, and at least one support structure 28. Preferably, a third rail 26 is movably installed between the first rail 22 and the second rail 24, and the third rail 26 is used for extending the moving stroke of the second rail 24 relative to the first rail 22.
The first rail 22 has a front portion 30a and a rear portion 30 b. The first bracket 18 is disposed adjacent to the front portion 30a of the first rail 22; the second bracket 20 is disposed adjacent to the rear portion 30b of the first rail 22. Further, the first rail 22 includes an upper wall 32a, a lower wall 32b, and a side wall 34 connected between the upper wall 32a and the lower wall 32b of the first rail 22, and the upper wall 32a, the lower wall 32b, and the side wall 34 of the first rail 22 together define a channel 36.
The third rail 26 is movably mounted to the channel 36 of the first rail 22. The third rail 26 includes an upper wall 38a, a lower wall 38b, and a side wall 40 connected between the upper wall 38a and the lower wall 38b of the third rail 26, and the upper wall 38a, the lower wall 38b, and the side wall 40 of the third rail 26 together define a channel 42.
The second rail 24 is movable relative to the first rail 22. Here, the second rail 24 is movable relative to the first rail 22 through the third rail 26 as an example. Specifically, the second rail 24 is movably mounted to the channel 42 of the third rail 26, and the second rail 24 has a front portion 59 and a rear portion 60. The second rail 24 includes an upper wall 43a, a lower wall 43b, and a side wall 45 connected between the upper wall 43a and the lower wall 43b of the second rail 24.
The at least one support structure 28 is arranged in a position relative to the first rail 22. For example, the at least one support structure 28 is connected to the first rail 22 via an extension 44, the extension 44 attached adjacent the rear portion 30b of the first rail 22, wherein the extension 44 is fixedly connected adjacent the rear portion 30b of the first rail 22 by riveting, welding, screwing or assembling; alternatively, in other embodiments, the extension member 44 is movably mounted adjacent the rear portion 30b of the first rail 22.
Preferably, in this embodiment, the at least one support structure 28 is two, for example, and each support structure 28 is a projection or a wall. Preferably, the extension 44 includes an upper portion 46a, a lower portion 46b, and a side portion 48 connected between the upper portion 46a and the lower portion 46b, and the upper portion 46a, the lower portion 46b, and the side portion 48 together define an extension channel 50.

The extension channel 50 is used for the second rail 24 to pass through, and the two support structures 28 are located at the upper and lower sides in the extension channel 50. For example, the two support structures 28 are secured to the upper portion 46a and the lower portion 46b of the extension member 44, respectively. Alternatively, the two support structures 28 are integrally formed on the upper portion 46a and the lower portion 46b of the extension member 44, so that the two support structures 28 and the extension member 44 can be seen as a single body. Alternatively, the two support structures 28 are movably mounted to the upper portion 46a and the lower portion 46b of the extension member 44, respectively, and thus, are not limited in implementation.
Preferably, the track assembly 16 further includes a sliding aid 52 mounted in the extended channel 50, the sliding aid 52 including a plurality of rolling members 54, the rolling members 54 being, for example, balls or rollers.
Preferably, the slide rail assembly 16 further includes a first connecting member 56 and a second connecting member 58. Wherein the first connecting member 56 is attached to the extending member 44; the second connector 58 is attached to the second rail 24. For example, the first connector 56 may be fixedly connected to the extension member 44 by riveting, welding, screwing or assembling; the second connector 58 may be fixedly attached adjacent the rear portion 60 of the second rail 24 by riveting, welding, threading or assembling.
