As shown in FIG. 1 and FIG. 2 , a support device 20 of one embodiment of the present invention includes a slide rail assembly and/or includes a first bracket 22 and a second bracket 24, and the first bracket 22 and the second bracket 24 can be longitudinally displaced relative to each other. Here, the X-axis direction is the longitudinal direction (or the length direction or displacement direction of the bracket), the Y-axis direction is the transverse direction (or the side direction of the bracket), and the Z-axis direction is the vertical direction (or the height direction of the bracket).

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, and the first wall 26a and the side wall 28 of the first bracket 22 are jointly arranged with at least one first ventilation hole H1. Here, a plurality of first ventilation holes H1 are taken as an example, and these first ventilation holes H1 are arranged with intervals in the vertical direction. Preferably, the second wall 26b and the side wall 28 of the first bracket 22 are also jointly arranged with a plurality of first ventilation holes H1.

Furthermore, the first bracket 22 (the side wall 28) has a first end 22a and a second end 22b that are opposite to each other, such as a front end and a rear end. A first end plate 30 is arranged adjacent to the first end 22a of the first bracket 22, and the first end plate 30 is substantially vertically bent relative to the side wall 28 of the first bracket 22, and at least one first mounting member 32 is disposed on the first end plate 30. In addition, the first bracket 22 (the side wall 28) has a first side S1 and a second side S2 that are opposite to each other.

Preferably, the first side S1 of the first bracket 22 and the second bracket 24 are retractably connected to each other. For example, the first wall 26a, the second wall 26b and the side wall 28 of the first bracket 22 jointly define a channel 34, and the channel opening of the channel 34 is adjacent to the second end 22b of the first bracket 22. The channel 34 is used to provide the second bracket 24 to be movably mounted to the first side S1 of the first bracket 22, and the second side S2 of the first bracket 22 is arranged with at least one slide rail. Here, the second side S2 of the first bracket 22 is arranged with a slide rail assembly 36 as an example.

The second bracket 24 has substantially the same ventilation hole structure configuration as the first bracket 22. For example, the second bracket 24 is arranged with at least one second ventilation hole H2. Specifically, 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, and the first wall 38a and the side wall 40 of the second bracket 24 are jointly arranged with the at least one second ventilation hole H2. Here, a plurality of second ventilation holes H2 are taken as an example, and these second ventilation holes H2 are arranged with intervals in the vertical direction. Preferably, the second wall 38b and the side wall 40 of the second bracket 24 are also jointly arranged with a plurality of second ventilation holes H2.

Furthermore, the second bracket 24 (side wall 40) has a first end 24a and a second end 24b that are positioned opposite to each other, such as a front end and a rear end. A second end plate 42 is arranged adjacent to the second end 24b of the second bracket 24, and the second end plate 42 is substantially vertically bent relative to the side wall 40 of the second bracket 24, and 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 telescopically connected to the channel 34 of the first bracket 22, and the second end plate 42 is located outside the channel 34 of the first bracket 22.

Preferably, the first bracket 22 and the second bracket 24 have different longitudinal lengths. For example, the side wall 28 of the first bracket 22 is longer than the side wall 40 of the second bracket 24, but the implementation is not limited.

Preferably, the first bracket 22 and the second bracket 24 are respectively provided with a first stopper 46 and a second stopper 48; through the mutual blocking of the first stopper 46 and the second stopper 48, the second bracket 24 can be prevented from escaping from the channel 34 of the first bracket 22, for example.

Preferably, the supporting device 20 further includes an elastic member 50 for providing elasticity to the first bracket 22 and the second bracket 24.

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

As shown in FIG3 , when the first bracket 22 and the second bracket 24 are at a predetermined position K1 relative to each other, the first vent H1 of the first bracket 22 and the second vent H2 of the second bracket 24 correspond to and are connected to each other. For example, at this time, the positions of the first vent H1 and the second vent H2 completely correspond to each other, and the first vent H1 and the second vent H2 are connected to both sides of the support device 20. It is worth mentioning that in this embodiment, a part of the first wall 26a (or the second wall 26b) of the first bracket 22 and the side wall 28 are jointly arranged with the first vent H1.

As shown in FIG. 4 , when the first bracket 22 and the second bracket 24 are at another predetermined position K2 relative to each other, the first vent H1 of the first bracket 22 and the second vent H2 of the second bracket 24 do not completely correspond to each other but are still connected. For example, at this time, a portion of the second bracket 24 (such as the first wall 38a or the side wall 40) will cover a portion of the first vent H1, and only a portion of the second vent H2 is connected to the other portion of the first vent H1. In short, the positions of the first vent H1 and the second vent H2 do not completely correspond to each other, but the first vent H1 and the second vent H2 are still connected to the two sides of the support device 20.

As shown in FIG5 , the slide rail assembly 36 includes a first rail 52 and a second rail 54 that can be longitudinally displaced relative to the first rail 52, and preferably, further includes a third rail 56 that is movably installed between the first rail 52 and the second rail 54. One of the first rail 52 and the third rail 56 is arranged with a first predetermined feature 58, and the other of the first rail 52 and the third rail 56 is arranged with a second predetermined feature 60. The first predetermined feature 58 and the second predetermined feature 60 are used in conjunction with each other. Here, the first predetermined feature 58 is arranged on the first rail 52, and the second predetermined feature 60 is arranged on the third rail 56 as an example. Preferably, the first predetermined feature 58 is a protrusion on an elastic member 59 (such as a spring, this part can be matched with FIG. 7), the two ends of the elastic member 59 are connected to the first rail 52, the first predetermined feature 58 is located between the two ends of the elastic member 59, and the second predetermined feature 60 is a protrusion; wherein, the first predetermined feature 58 has a first guide surface 62a and a second guide surface 62b that are relatively positioned, and the first guide surface 62a and the second guide surface 62b are, for example, arc surfaces or inclined surfaces; on the other hand, the second predetermined feature 60 has a first guide structure 64a and a second guide structure 64b that are relatively positioned, and the first guide structure 64a and the second guide structure 64b are, for example, arc surfaces or inclined surfaces.

As shown in Fig. 6, the support device 20 is suitable for a frame 66, which includes a first column 68a and a second column 68b, and there is a first longitudinal distance between the first column 68a and the second column 68b. When the first bracket 22 and the second bracket 24 are at the predetermined position K1 relative to each other, the first mounting member 32 of the first bracket 22 and the second mounting member 44 of the second bracket 24 can be mounted to the first column 68a and the second column 68b respectively. The first ventilation hole H1 of the first bracket 22 and the second ventilation hole H2 of the second bracket 24 correspond to and are connected to each other; in addition, the first rail 52 of the slide rail assembly 36 is connected (for example, fixed) to the second side S2 of the first bracket 22, and the second rail 54 is used to carry an electronic device 70, and the second rail 54 is in a retracted position R relative to the first rail 52.

When the first bracket 22 and the second bracket 24 are respectively mounted on the first column 68a and the second column 68b, the positions of the first vent H1 of the first bracket 22 and the second vent H2 of the second bracket 24 correspond to each other, and the first vent H1 and the second vent H2 are connected to both sides of the support device 20 to provide heat dissipation for a predetermined portion 72 of the electronic device 70.

Among them, since a part of the first wall 26a (second wall 26b) of the first bracket 22 and the side wall 28 are jointly arranged with the first vent H1, and a part of the first wall 38a (second wall 38b) of the second bracket 24 and the side wall 40 are jointly arranged with the second vent H2, the heat energy of the electronic device 70 can be dissipated from the sides of the first bracket 22 and the second bracket 24, and can also be dissipated from the top or bottom of the first bracket 22 and the second bracket 24 (i.e., the Z-axis direction).

It is worth mentioning that when the first bracket 22 and the second bracket 24 are at the above-mentioned other predetermined position K2 relative to each other, the first mounting member 32 of the first bracket 22 and the second mounting member 44 of the second bracket 24 can be respectively used to be mounted to the first column and the second column of another frame, and the first column and the second column of the other frame have a second longitudinal distance between them that is different from the first longitudinal distance between the first column 68a and the second column 68b.

As shown in Figures 7 to 10, when the first bracket 22 and the second bracket 24 are at the predetermined position K1 relative to each other and are respectively mounted on the first column 68a and the second column 68b, the first vent H1 of the first bracket 22 and the second vent H2 of the second bracket 24 correspond to each other and are connected to provide heat dissipation for the electronic device 70 (not shown, this part can be combined with Figure 6) on the second rail 54.

The second rail 54 and the third rail 56 are at the retracted position R relative to the first rail 52. Preferably, the second rail 54 and the third rail 56 can move together from the retracted position R (as shown in FIG. 7 ) to a predetermined direction D1 (e.g., opening direction) (as shown in FIG. 8 to FIG. 10 ) through a synchronization mechanism, and the synchronization mechanism can be released by an auxiliary feature on the first rail 52 at a predetermined stroke. Since this part is a technical scope that can be understood by those with ordinary knowledge in the field, it will not be further described here for the sake of simplicity.

Furthermore, when the second rail 54 and the third rail 56 are displaced from the retracted position R (as shown in FIG. 7 ) to the predetermined direction D1 relative to the first rail 52, the first guide structure 64a of the second predetermined feature 60 and the first guide surface 62a of the first predetermined feature 58 are in contact with each other to generate friction resistance (as shown in FIG. 8 ), so as to slow down the speed of the third rail 56 and the second rail 54 when they are displaced to the predetermined direction D1 relative to the first rail 52, wherein the first predetermined feature 58 can be elastically deformed to accumulate an elastic force (as shown in FIG. 9 ). Furthermore, if the third rail 56 and the second rail 54 continue to move in the predetermined direction D1, the second predetermined feature 60 can pass over the first predetermined feature 58 (as shown in FIG. 10 ), and the first predetermined feature 58 restores the elastic force. It can be seen that since the speed of the third rail 56 and the second rail 54 moving in the predetermined direction D1 relative to the first rail 52 is slowed down, the impact force generated by the second rail 54 (and the electronic device 70) moving in the predetermined direction D1 too fast can be avoided, which has a safety and/or protection effect.

Similarly, when the second rail 54 and the third rail 56 are displaced from an extended position to another predetermined direction D2 (for example, a folding direction) opposite to the predetermined direction D1 relative to the first rail 52, the second guide structure 64b of the second predetermined feature 60 and the second guide surface 62b of the first predetermined feature 58 can contact each other to generate friction resistance (as shown in FIG. 10), so as to slow down the speed of the third rail 56 and the second rail 54 when they are displaced to the other predetermined direction D2 relative to the first rail 52 (as shown in FIG. 9), until the second predetermined feature 60 passes over the first predetermined feature 58 (as shown in FIG. 8). It can be seen that, since the speed of the third rail 56 and the second rail 54 when displacing in the other predetermined direction D2 relative to the first rail 52 is slowed down, the impact force caused by the second rail 54 (and the electronic device 70) displacing in the other predetermined direction D2 too fast can be avoided, which has a safety and/or protection effect.

It can be seen that the support device 20 of the embodiment of the present invention includes the following features:

1. When one of the two slide rails (e.g. the third rail 56) moves relative to the other one (e.g. the first rail 52) in the predetermined direction D1, the first predetermined feature 58 and the second predetermined feature 60 contact each other to generate friction resistance, which is used to slow down the speed of one of the two slide rails moving relative to the other one in the predetermined direction D1, and has a safety and/or protection effect.

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 second predetermined feature 60 and the first predetermined feature 58 are in contact with each other to generate friction resistance, which is used to slow down the speed of the third rail 56 and the second rail 54 displacing in the predetermined direction D1 relative to the first rail 52, and avoid the impact force generated by the second rail 54 (and the electronic device 70) displacing in the predetermined direction D1 too fast, which has a safety and/or protection effect.

3. Since a portion of the first wall 26a (second wall 26b) of the first bracket 22 and the side wall 28 are jointly arranged with the first vent H1, and a portion of the first wall 38a (second wall 38b) of the second bracket 24 and the side wall 40 are jointly arranged with the second vent H2, the heat energy of the electronic device 70 can be dissipated from the sides of the first bracket 22 and the second bracket 24, as well as from the top or bottom of the first bracket 22 and the second bracket 24.

Although the present invention has been disclosed by the above preferred embodiments, they are not intended to limit the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of the attached patent application.
