DETAILED DESCRIPTION OF THE INVENTION

[0011] In the following detailed description of the preferred embodiment, reference is made to the accompanying drawings, which form a part hereof, and in which is shown, by way of illustration, specific embodiments in which the invention may be practiced. In this regard, directional terms such as "top," "bottom," "left," "right," "front," and "rear" are used with reference to the orientation of the figures being described. Components of the invention may be oriented in many different directions. As such, directional terminology is used for purposes of explanation and is in no way limiting. Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive. Furthermore, unless specified, the term "connect" is intended to mean either an indirect or direct mechanical connection. Thus, when a first device is connected to a second device, the connection may be via a direct mechanical connection or via an indirect mechanical connection via a connection to another device.

[0012] 1 and 2, the support device 20 includes a slide rail assembly 36 and / or includes a first bracket 22 and a second bracket 24 that is longitudinally displaceable relative to the first bracket 22. In this embodiment, by way of example, the longitudinal direction is defined by the length of the bracket, e.g., the first bracket 22 or the second bracket 24, and may be parallel to the X-axis. The transverse direction is defined by the lateral or width direction of the bracket, e.g., the first bracket 22 or the second bracket 24, and may be parallel to the Y-axis. The vertical direction is defined by the height of the bracket, e.g., the first bracket 22 or the second bracket 24, and may be parallel to the Z-axis.

[0013] The support device 20 further includes at least one first vent hole structure H1 disposed on the first bracket 22. In this embodiment, for example, the support device 20 includes a plurality of first vent hole structures H1 arranged at intervals in the longitudinal direction.

[0014] 2 to 4 , the first bracket 22 includes a first wall 26a, a second wall 26b, and a side wall 28 connected between the first wall 26a and the second wall 26b of the first bracket 22. The first vent structure H1 includes a first portion P1A and a second portion P2A, where the first portion P1A of the first vent structure H1 is disposed in one of the first wall 26a and the second wall 26b of the first bracket 22, and the second portion P2A of the first vent structure H1 is disposed in the side wall 28 of the first bracket 22.

[0015] Preferably, the first portion P1A of the first vent hole structure H1 in the first wall 26a or the second wall 26b of the first bracket 22 communicates with the second portion P2A of the first vent hole structure H1 in the side wall 28 of the first bracket 22.

[0016] Furthermore, the first bracket 22 or the side wall 28 (longitudinal wall 28) of the first bracket 22 includes a first end 22a and a second end 22b longitudinally opposite the first end 22a. In this embodiment, for example, the first end 22a and the second end 22b of the first bracket 22 are the front and rear ends of the first bracket 22, respectively. A first end plate 30 is disposed adjacent to the first end 22a of the first bracket 22 and substantially perpendicular to the side wall 28 of the first bracket 22. At least one first mounting member 32 is disposed on the first end plate 30. Furthermore, the first bracket 22 or the side wall 28 of the first bracket 22 includes a first side S1 and a second side S2 transversely opposite the first side S1.

[0017] Preferably, the second bracket 24 is connected to the first side S1 of the first bracket 22 in a longitudinally telescopic manner. In this embodiment, for example, the first wall 26a, the second wall 26b, and the side wall 28 of the first bracket 22 cooperate to define a channel 34 of the first bracket 22 located on the first side S1 of the first bracket 22. An entrance to the channel 34 of the first bracket 22 is located adjacent to the second end 22b of the first bracket 22 to allow the second bracket 24 to be movably mounted in the channel 34 located on the first side S1 of the first bracket 22. Furthermore, the second side S2 of the first bracket 22 is configured to accommodate at least one slide rail. In this embodiment, for example, the second side S2 of the first bracket 22 is configured to accommodate a slide rail assembly 36, which includes multiple slide rails that are longitudinally displaceable relative to one another.

[0018] The support device 20 further includes at least one second vent structure H2 disposed on the second bracket 24. In this embodiment, for example, the support device 20 includes a plurality of second vent structures H2 arranged at intervals in the longitudinal direction. The second vent structure H2 and the first vent structure H1 may have substantially the same structure. Specifically, as shown in FIGS. 2 to 4 , the second bracket 24 includes a first wall 38a, a second wall 38b, and a side wall 40 connected between the first wall 38a and the second wall 38b of the second bracket 24. The second vent structure H2 includes a first portion P1B and a second portion P2B, and the first portion P1B of the second vent structure H2 is disposed on one of the first wall 38a and the second wall 38b of the second bracket 24. The second portion P2B of the second vent structure H2 is disposed on the side wall 40 of the second bracket 24.

[0019] Furthermore, the second bracket 24 or the side wall 40 of the second bracket 24 includes a first end 24a and a second end 24b longitudinally opposite the first end 24a. In this embodiment, for example, the first end 24a and the second end 24b of the second bracket 24 are the front and rear ends of the second bracket 24, respectively. The second end plate 42 is disposed adjacent to the second end 24b of the second bracket 24 and substantially perpendicular to the side wall 40 of the second bracket 24. At least one second mounting member 44 is disposed on the second end plate 42. The side wall 40 of the second bracket 24 is connected to the channel 34 of the first bracket 22 in a longitudinally telescopic manner, and the second end plate 42 is disposed outside the channel 34 of the first bracket 22.

[0020] Preferably, the first bracket 22 and the second bracket 24 have different longitudinal lengths. In this embodiment, for example, the longitudinal length of the side wall 28 of the first bracket 22 is greater than the longitudinal length of the side wall 40 of the second bracket 24. However, the present invention is not limited to this embodiment.

[0021] Preferably, a first blocking portion 46 and a second blocking portion 48 are disposed on the first bracket 22 and the second bracket 24, respectively. The first bracket 22 and the second bracket 24 are configured to block each other, for example, to prevent the second bracket 24 from disengaging from the channel 34 of the first bracket 22.

[0022] Preferably, the support device 20 further includes a resilient member 50 configured to apply a resilient force to the first bracket 22 and the second bracket 24 .

[0023] Preferably, the first wall 26a, the second wall 26b, and the side wall 28 of the first bracket 22 are configured to support the first wall 38a, the second wall 38b, and the side wall 40 of the second bracket 24, respectively.

[0024] As shown in FIG. 3 , when the second bracket 24 is in a predetermined position K1 relative to the first bracket 22, the first vent hole structure H1 is located at a position corresponding to the second vent hole structure H2 and communicates with the second vent hole structure H2. For example, the first vent hole structure H1 is perfectly aligned with the second vent hole structure H2. Air communication between the two sides of the support device 20 is enabled through the first vent hole structure H1 and the second vent hole structure H2. Note that in this embodiment, the first portion P1A of the first vent hole structure H1 is located within a predetermined area of ​​the first wall 26 a or the second wall 26 b of the first bracket 22, and the second portion P2A of the first vent hole structure H1 is located within a predetermined area of ​​the side wall 28 of the first bracket 22.

[0025] 4, when the second bracket 24 is in another predetermined position K2 relative to the first bracket 22, the first vent hole structure H1 is not fully aligned with the second vent hole structure H2 and is partially in communication with the second vent hole structure H2; for example, the first vent hole structure H1 is partially covered by a portion of the second bracket 24, such as the first wall 38a, the second wall 38b, or the side wall 40 of the second bracket 24. The uncovered portion of the first vent hole structure H1 is in communication with a portion of the second vent hole structure H2. This still allows air communication between the two sides of the support apparatus 20 via the first vent hole structure H1 and the second vent hole structure H2.

[0026] As shown in FIG. 5 , slide rail assembly 36 includes a first rail 52 and a second rail 54 that is longitudinally displaceable relative to first rail 52. Preferably, slide rail assembly 36 further includes a third rail 56 that is movably mounted between first rail 52 and second rail 54. In other words, in this embodiment, slide rail assembly 36 includes three slide rails: first rail 52, second rail 54, and third rail 56. Second rail 54 may be considered an additional slide rail to first rail 52 and third rail 56. A first predetermined feature 58 is disposed on one of first rail 52 and third rail 56. A second predetermined feature 60 is disposed on the other of first rail 52 and third rail 56. First predetermined feature 58 and second predetermined feature 60 are configured to cooperate with each other. In this embodiment, for example, the first predetermined feature 58 is disposed on the first rail 52, and the second predetermined feature 60 is disposed on the third rail 56. Preferably, as shown in FIG. 7 , the first predetermined feature 58 is a protrusion portion of an elastic structure 59, such as an elastic clip, connected to the first rail 52. The second predetermined feature 60 is a section of the protrusion. The first predetermined feature 58 includes a first guide surface 62a and a second guide surface 62b that is longitudinally opposite the first guide surface 62a. In this embodiment, for example, the first guide surface 62a and the second guide surface 62b are inclined or arcuate surfaces. Furthermore, the second predetermined feature 60 includes a first guide structure 64a and a second guide structure 64b that is longitudinally opposite the first guide structure 64a. In this embodiment, for example, the first guide structure 64a and the second guide structure 64b are inclined or arcuate surfaces.

[0027] As shown in FIG. 6 , the support device 20 is fitted to a rack 66. The rack 66 includes a first post 68 a and a second post 68 b, which are spaced apart from each other by a first longitudinal distance. When the second bracket 24 is in a predetermined position K1, the first mounting member 32 of the first bracket 22 and the second mounting member 44 of the second bracket 24 are configured to be attached to the first post 68 a and the second post 68 b, respectively, and the first vent structure H1 and the second vent structure H2 are configured to be aligned and communicate with each other. Additionally, as shown in FIG. 6 , the first rail 52 of the slide rail assembly 36 is connected, e.g., fixedly connected, to the second side S2 of the first bracket 22. The second rail 54 is in a retracted position R relative to the first rail 52 and is configured to support an electronic device 70.

[0028] When the first bracket 22 and the second bracket 24 are attached to the first post 68a and the second post 68b, respectively, the first vent hole structure H1 and the second vent hole structure H2 are aligned and communicated with each other, thereby enabling air communication between the two sides of the support device 20 via the first vent hole structure H1 and the second vent hole structure H2 to dissipate heat generated from a predetermined portion 72 of the electronic device 70.

[0029] The first vent hole structure H1 includes a first portion P1A on the first wall 26a or the second wall 26b of the first bracket 22 and a second portion P2A on the side wall 28 of the first bracket 22 that is in communication with the first portion P1A. The second vent hole structure H2 includes a first portion P1B on the first wall 38a or the second wall 38b of the second bracket 24 and a second portion P2B on the side wall 40 of the second bracket 24 that is in communication with the first portion P1B. This allows heat generated from a predetermined portion 72 of the electronic device 70 to be dissipated in the transverse direction, i.e., along the Y-axis, through the second portion P2A of the first vent hole structure H1 and the second portion P2B of the second vent hole structure H2, and to be dissipated in the vertical direction, i.e., along the Z-axis, through the first portion P1A of the first vent hole structure H1 and the first portion P1B of the second vent hole structure H2.

[0030] It should be noted that when the second bracket 24 is in another predetermined position K2, the first mounting member 32 of the first bracket 22 and the second mounting member 44 of the second bracket 24 are configured to be attached to a first post and a second post, respectively, of another rack. The first post and the second post are spaced apart from each other by a second longitudinal distance, different from the first longitudinal distance, between the first post 68a and the second post 68b of the rack 66.

[0031] As shown in Figures 7 to 10, as described above, when the second bracket 24 is in a predetermined position K1 relative to the first bracket 22 and the first bracket 22 and the second bracket 24 are attached to the first post 68a and the second post 68b, respectively, the first ventilation hole structure H1 and the second ventilation hole structure H2 are in corresponding positions and communicate with each other to dissipate heat generated from a predetermined portion 72 of the electronic device 70 on the second rail 54.

[0032] As shown in Fig. 7, the second rail 54 and the third rail 56 are retracted relative to the first rail 52. Preferably, when the second rail 54 is displaced relative to the first rail 52 in a predetermined direction D1, for example, the opening direction D1, from the retracted position shown in Fig. 7, the second rail 54 and the third rail 56 can be displaced synchronously in the predetermined direction D1 by a synchronization mechanism. Thereafter, when the second rail 54 and the third rail 56 have been displaced synchronously in the predetermined direction D1 by a predetermined distance, the synchronization mechanism can be terminated by an auxiliary feature on the first rail 52. For simplicity, a detailed description of the synchronization mechanism will be omitted in this specification.

[0033] 7 to 10, when the second rail 54 and the third rail 56 are displaced in the predetermined direction D1 relative to the first rail 52, the first guide structure 64a of the second predetermined feature 60 can abut against the first guide surface 62a of the first predetermined feature 58, generating a resistance force to reduce the displacement speed of the third rail 56 and the second rail 54 in the predetermined direction D1 relative to the first rail 52. As shown in FIG. 9, the first predetermined feature 58 can elastically deform and accumulate an elastic force. As shown in FIG. 10, when the second rail 54 and the third rail 56 are further displaced in the predetermined direction D1 relative to the first rail 52 and the second predetermined feature 60 is driven to pass the first predetermined feature 58, the first predetermined feature 58 returns to its original position to release the elastic force. It can be understood that the aforementioned abutment between the first predetermined feature 58 and the second predetermined feature 60 can reduce the displacement speed of the third rail 56 and the second rail 54 in the predetermined direction D1 relative to the first rail 52. Therefore, any impact caused by an excessive displacement speed of the second rail 54 or an excessive displacement speed of the electronic device 70 in the predetermined direction D1 can be prevented, thereby achieving a safety and / or protection effect.

[0034] Similarly, as shown in Figures 7 to 10, when the second rail 54 and the third rail 56 are displaced relative to the first rail 52 in another predetermined direction D2 opposite to the predetermined direction D1, such as a backward direction, the second guide structure 64b of the second predetermined feature 60 can abut against the second guide surface 62b of the first predetermined feature 58. This reduces the displacement speed of the third rail 56 and the second rail 54 in the other predetermined direction D2 relative to the first rail 52, for example, by moving from the position shown in Figure 10 to the position shown in Figure 9 and then to the position shown in Figure 8, until the second predetermined feature 60 passes the first predetermined feature 58. It can be understood that the abutment between the first predetermined feature 58 and the second predetermined feature 60 described above can reduce the displacement speed of the third rail 56 and the second rail 54 in the other predetermined direction D2 relative to the first rail 52. Therefore, any impact caused by an excessive displacement speed of the second rail 54 in another predetermined direction D2 or an excessive displacement speed of the electronic device 70 can be prevented, and safety and / or protection effects can be achieved.

[0035] As described above, the support device 20 of the present invention has the following features.

[0036] 1. When one of the slide rails, for example, the third rail 56, is displaced in a predetermined direction D1 relative to another one of the slide rails, for example, the first rail 52, the first predetermined feature 58 and the second predetermined feature 60 can butt against each other, generating a frictional resistance force to reduce the displacement speed of one of the slide rails relative to the other one of the slide rails in the predetermined direction D1, thereby achieving a safety and / or protection effect.

[0037] 2. When the second rail 54 and the third rail 56 are displaced in the predetermined direction D1 relative to the first rail 52, the first predetermined feature 58 and the second predetermined feature 60 abut against each other, generating a frictional resistance force that reduces the displacement speed of the third rail 56 and the second rail 54 in the predetermined direction D1 relative to the first rail 52. This prevents any impact caused by an excessive displacement speed of the second rail 54 or an excessive displacement speed of the electronic device 70 in the predetermined direction D1, thereby achieving safety and / or protection effects.

[0038] 3. The first portion P1A of the first vent hole structure H1 in the first wall 26a or the second wall 26b of the first bracket 22 communicates with the second portion P2A of the first vent hole structure H1 in the side wall 28 of the first bracket 22. The first portion P1B of the second vent hole structure H2 in the first wall 38a or the second wall 38b of the second bracket 24 communicates with the second portion P2B of the second vent hole structure H2 in the side wall 40 of the second bracket 24. Therefore, heat generated from a predetermined portion 72 of the electronic device 70 can be dissipated in the transverse direction, i.e., along the Y axis, through the second portion P2A of the first vent hole structure H1 and the second portion P2B of the second vent hole structure H2, and can be dissipated in the vertical direction, i.e., along the Z axis, through the first portion P1A of the first vent hole structure H1 and the first portion P1B of the second vent hole structure H2.

[0039] Those skilled in the art will readily recognize that numerous modifications and variations of the apparatus and method may be made while retaining the teachings of the present invention. Accordingly, it is intended that the above disclosure be construed as limited only by the metes and bounds of the appended claims.
