The following examples further illustrate aspects of the present invention in detail, but are not intended to limit the scope of the invention in any way.

Please refer to fig. 1 to 3. Fig. 1 is a perspective view of a servo device and a filter device thereof according to a first embodiment of the invention. Fig. 2 is a partially exploded view of the servo apparatus of fig. 1. Fig. 3 is a partial cross-sectional view of the servo apparatus of fig. 1. A server 1 of the present embodiment includes a cabinet 10, a network switch 20, a filtering device 30 and two fixing plates 40.

The cabinet 10 includes two fixing posts 11 and two first sliding rails 12. Two first slide rails 12 are disposed on the two fixing posts 11.

The network switch 20 includes a housing 21, two second sliding rails 22, and an electronic component 23. The housing 21 includes a front plate 211, a top plate 212 and two side plates 213. The front plate 211, the top plate 212 and the two side plates 213 together form an accommodating space 214. The electronic component 23 is located in the accommodating space 214. The front plate 211 has a plurality of connection ends 2111 and a plurality of air inlets 2112. The top plate 212 has a plurality of card slots 2121. The two second slide rails 22 are respectively disposed on the two side plates 213, and are drawably disposed on the two first slide rails 12 of the cabinet 10.

The filter device 30 includes a filter frame 31 and an assembly frame 32. The filter rack 31 includes a rack 311 and a filter 312.

The frame 311 includes a first support 3111, a second support 3112 and a third support 3113. The second support 3112 and the third support 3113 are respectively connected to two opposite ends of the first support 3111 and extend in the same direction to form a first yielding space 313. Specifically, the frame 311 is a U-shaped frame composed of three brackets, thereby forming a first offset space 313. The first support 3111 has a first vent 31111, the second support 3112 has a second vent 31121, and the third support 3113 has a third vent 31131. The first ventilating opening 31111, the second ventilating opening 31121 and the third ventilating opening 31131 are all communicated with the first relief space 313. The third vent 31131 of the third rack 3113 is further in communication with an inlet 2112 of the network exchanger 20. The screen 312 includes a first filtering section 3121, a second filtering section 3122 and a third filtering section 3123 connected together. The first filter segment 3121, the second filter segment 3122, and the third filter segment 3123 are disposed at the first bracket 3111, the second bracket 3112, and the third bracket 3113, respectively. In detail, each bracket has a concave structure for mounting three filtering sections.

The assembly frame 32 includes a first plate 321, a second plate 322, a third plate 323, two limiting plates 324, two assembly plates 325, and three engaging plates 326. The first plate 321 has a second relief space 3211 extending from a side connected to the third plate 323 toward a direction close to the second plate 322, and the second relief space 3211 is communicated with the first relief space 313. The first plate member 321 further has an air inlet 3212. The air inlet 3212 communicates with a third vent 31131 of the third rack 3113. The second plate 322 and the third plate 323 are respectively connected to two opposite sides of the first plate 321, and the two limiting plates 324 are connected to two sides of the first plate 321 and between the second plate 322 and the third plate 323, so that the first plate 321, the second plate 322, the third plate 323, and the two limiting plates 324 together form an accommodating groove 327, and can be used for limiting the filter holder 31 in the accommodating groove 327. The three engaging plates 326 are connected to a side of the second plate 322 away from the first plate 321, and extend toward the third plate 323 to cover a portion of the receiving groove 327. Each of the snap-fit plates 326 includes a release section 3261 and a snap-fit section 3262 connected thereto. The two assembly plates 325 are respectively connected to the two limiting plates 324 and extend in opposite directions of the receiving groove 327.

In the present embodiment, the three engaging plates 326 of the assembling frame 32 are respectively connected to the left, middle and right positions of the second plate 322. Therefore, the filtering device 30 can be engaged with the network switch 20 with an even force without tilting or tilting, but not limited thereto. In other embodiments, the number of snap plates 326 may be other.

It should be noted that, since the filter frame 31 has the first yielding space 313 and the assembly frame 32 has the second yielding space 3211, and neither side of the two yielding

spaces

313 and 3211 is blocked by a frame body to form a gap. Therefore, the filter device 30 can be directly hung on the network switch 20 from top to bottom through the gaps of the yielding

spaces

313 and 3211, so that the wires connected to the connection end 2111 on the network switch 20 are located in the yielding spaces without interfering with the filter device 30. On the contrary, when the filter device 30 needs to be disassembled, the filter device 30 is also directly pulled upward away from the network switch 20 by the gaps of the

relief spaces

313, 3211. That is, the wires inserted into the connection end 2111 do not need to be removed before the installation and removal operations of the filtering device 30 and the network switch 20, so as to improve the assembling and disassembling efficiency of the filtering device 30.

Each fixing plate 40 includes a first fixing portion 41, a second fixing portion 42 and a third fixing portion 43. The second fixing portion 42 and the third fixing portion 43 are respectively connected to two opposite sides of the first fixing portion 41. The two first fixing portions 41 are fixed to the two side plates 213 of the network switch 20, respectively. Each second fixing portion 42 has two screw holes 421, and the second fixing portion 42 is fastened to the fixing column 11 of the cabinet 10 by screws, for example. The third fixing portion 43 is fixed to the assembly plate 325. The projection of the third fixing portion 43 on the second fixing portion 42 does not overlap with the two screw holes 421 of the second fixing portion 42. Therefore, the screw hole 421 of the second fixing portion 42 is not shielded by the third fixing portion 43 to affect the locking operation.

Next, the assembling method of the filter device 30 will be further described. Referring to fig. 4 and 5, fig. 4 is a perspective view illustrating a first step in an assembling process of the filter device in fig. 1, and fig. 5 is a perspective view illustrating a second step in the assembling process of the filter device in fig. 1. First, the first bracket 3111 of the filter rack 31 with the filter screen 312 is disposed in the receiving groove 327 and leans against the second plate 322, so that the first bracket 3111 is limited by the first plate 321 and the engaging plate 326 and is located between the first plate 321 and the engaging plate 326. Next, the second support 3112 and the third support 3113 of the filter rack 31 are placed in the receiving groove 327, and the filter rack 31 is temporarily engaged in the receiving groove 327 by the interference of the third plate 323 with the second support 3112 and the third support 3113. In this way, the assembly of the filter device 30 is completed.

Next, the operation flow of the filtering device 30 installed in the network switch 20 will be described. Please refer to fig. 1 to fig. 3. According to the above, since the filter rack 31 is temporarily engaged with the receiving groove 327 of the assembly rack 32, the filter rack 31 will not fall out of the assembly rack 32 and affect the operation during the process of assembling the filter device 30 and the network switch 20. First, each of the clamping plates 326 is aligned with each of the slots 2121 of the network switch 20, so that the clamping plate 326 can be pushed into the slot 2121 along the extending direction of the release section 3261. After the engaging plate 326 completely enters the slot 2121, the filter device 30 is pushed along the extending direction of the engaging section 3262, so that the engaging section 3262 can be engaged by the top plate 212 of the network switch 20, and the air inlet 3212 of the filter device 30 can be aligned with the air inlet 2112 of the network switch 20. Next, the left and right assembly plate members 325 of the filter device 30 are respectively locked to the left and right third fixing portions 43 of the fixing plate member 40 by, for example, hand-turning screws. Thus, the assembly of the filtering device 30 and the network switch 20 is completed. When the filter device 30 is installed in the network switch 20, before the external air flow is guided to be sucked into the network switch 20, the air flow enters the third ventilating opening 31131 through the air inlet 3212 of the filter device 30, then passes through the filter screen 312 through the third ventilating opening 31131, and then enters the network switch 20 through the air inlet 2112. Therefore, the air flow is filtered by the filtering device 30 before entering the network exchanger 20, and the proportion of the dust entrained in the air flow can be reduced.

In addition, in the embodiment, the fixing plate 40, the network switch 20, the filtering device 30 and the cabinet 10 are assembled by screwing in the screw holes, but not limited thereto. In other embodiments, the three components can be fixed by a snap or the like.

According to the servo device and the filtering device thereof in the embodiment, the filtering device is additionally arranged at the air inlet of the network exchanger to filter the air flow entering the network exchanger, so that the influence of dust in the air entering the network exchanger on the transmission speed of the network exchanger can be avoided.

Furthermore, a gap is formed because one side of the yielding space is not blocked by the frame body. Therefore, the filter device can be directly hung on the network switch from top to bottom by the gap of the yielding space, or the filter device can be directly pulled out of the network switch from top to bottom. That is to say, the wire inserted into the connecting end does not need to be pulled out before the installation and the disassembly operation of the filtering device and the network exchanger, and the loading and unloading efficiency of the filtering device can be further improved.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
