Description

Technical Field

[0001] This invention relates to a server chassis, and more particularly to a server chassis with a telescopic mechanism and a server with a telescopic mechanism. Background Technology

[0002] With advancements in technology, hard drive storage capacities are increasing, and hard drives themselves are becoming more sensitive to external influences. For example, sound waves or other vibrations can reduce hard drive read performance. Furthermore, server chassis require a greater number of hard drives to accommodate within the system. When most of the system space is used for hard drives, the distance between the fans and the hard drives becomes increasingly closer. The sound waves generated by the high-speed fans can then affect the hard drives, reducing their read performance. Summary of the Invention

[0003] In view of this, in one embodiment, a server chassis with a telescopic device is provided, including a chassis, a drawer body, and a telescopic device. The drawer body is housed within the chassis. The telescopic device has a first end, a second end, and a telescopic structure. The second end is connected to the drawer body, and the telescopic structure connects the first end and the second end. The distance between the first end and the second end is variable. The distance between the first end and the second end is changed by moving the drawer body from within the chassis until at least a portion of the drawer body is outside the chassis.

[0004] In some embodiments, the telescopic structure includes a telescopic rod assembly, which is a pneumatic rod or a telescopic rod and a spring. The telescopic device includes a first body and a second body, the first body being located at a first end and the second body being located at a second end. The telescopic rod assembly connects the first body and the second body and provides a force to cause the first body to move relative to the second body.

[0005] In some embodiments, the telescopic structure includes a telescopic sleeve containing a plurality of bends that unfold when the drawer body is outside the chassis.

[0006] In some embodiments, the telescopic device further includes a limiting component having a continuous cross structure. The first body is provided with a first limiting hole and a first pivot hole, which are located on opposite sides of the first body. The second body is provided with a second limiting hole and a second pivot hole, which are located on opposite sides of the second body. The continuous cross structure includes two movable parts and two fixed parts. The two movable parts are respectively movably inserted through the first limiting hole and the second limiting hole, and the two fixed parts are respectively pivotally connected to the first pivot hole and the second pivot hole.

[0007] In some embodiments, the telescopic structure includes a sliding part and a sliding portion. The sliding part is disposed on the first body and the sliding portion is disposed on the second body. The first body and the second body are slidably connected to each other through the sliding part and the sliding portion.

[0008] In some embodiments, the telescopic device further includes a driver electrically connected to the telescopic rod assembly, and the chassis further includes a sensor signal connected to the driver. When the sensor senses a signal and transmits it to the driver, the driver causes the telescopic rod assembly to actuate, causing the first body to move relative to the second body.

[0009] In some embodiments, the telescopic device further includes a storage structure disposed between the first body and the second body, the shape of which changes when the first body moves relative to the second body.

[0010] In some embodiments, the housing structure is a plurality of housings or hoses, wherein the plurality of housings are pivotally connected to each other.

[0011] In some embodiments, the telescopic device further includes rollers disposed on the telescopic device.

[0012] In some embodiments, a fan bracket is also included, which is disposed at the first end of the telescopic device.

[0013] In some embodiments, the telescopic device further includes a baffle plate disposed at the first end, and the chassis includes an opening. When the first end of the telescopic device passes through the opening, the baffle plate abuts against the wall of the chassis adjacent to the opening.

[0014] In another embodiment, a server with a telescopic device is provided, including a chassis, a drawer body, a telescopic device, a hard drive assembly, and a fan bracket. The drawer body is housed within the chassis. The telescopic device has a first end, a second end, and a telescopic structure. The second end is connected to the drawer body, and the telescopic structure connects the first end and the second end. The distance between the first end and the second end is variable. The hard drive assembly is housed within the drawer body. A fan module is disposed at the first end of the telescopic device. The distance between the first end and the second end is changed by moving the drawer body from within the chassis until at least a portion of the drawer body is outside the chassis.

[0015] In summary, based on the above embodiments, a server chassis with a telescopic device can house hard drive units within a drawer body, which is housed within the chassis. Since the hard drive units within the server chassis are replaced by pulling out the drawer body, during maintenance or replacement, the drawer body is moved outside the chassis. Because the drawer body is not completely sealed, the fan speed increases to facilitate heat dissipation. The high-frequency sound waves generated by the high-speed fan can then affect the read performance of the hard drive unit near the fan. Because the drawer body is connected to the chassis via a telescopic device, pulling out the drawer body simultaneously pulls the telescopic device, causing it to move with the drawer body. This changes the distance between the first and second ends of the telescopic structure, increasing the distance between the fan and the hard drive unit. This achieves the goal of increasing the distance between the fan and the hard drive unit within a limited space, thereby reducing the impact of fan noise on hard drive read performance.

[0062] Please also refer to Figure 1 , Figure 2 and Figure 3 This invention discloses, in one embodiment, a server chassis 100 with a telescopic device, comprising a chassis 10, a drawer body 30, and a telescopic device 50.

[0063] In this embodiment, the chassis 10 is a rack-mount server chassis, which houses at least one rack-mount server. The height of the rack-mount server is measured in U (1U equals 1.75 inches, which equals 44.45 mm). The chassis 10 can accommodate, for example, but is not limited to, standard rack-mount servers ranging from 1U to 7U. In this embodiment, a hard disk drive 70 is housed within the drawer body 30. In this embodiment, the telescopic device 50 may, for example, include a fan module 90. In this embodiment, as... Figure 3 As shown, when the server chassis 100 with the telescopic device pulls out the drawer body 30, it moves the telescopic device 50, changing the distance between the fan module 90 and the hard disk drive 70. This attenuates sound wave energy, reduces the noise generated by the airflow from the fan module 90 on the hard disk drive 70, and simultaneously maintains the heat dissipation effect of the server chassis. The fan module 90 can generate airflow in the form of exhaust or blowing. The following description uses an exhaust-type fan module as an example, but it is not limited to this.

[0064] Here, the telescopic device 50 can be a standalone kit. One or more telescopic devices 50 can be installed to match different sizes of chassis 10, such as, but not limited to, server chassis of different heights such as 1U, 2U and 3U, or server chassis of different widths.

[0065] Please also refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 .like Figure 2 and Figure 3 As shown, Figure 2 The drawer body 30 is placed inside the chassis 10. Figure 3The drawer body 30 is located outside the chassis 10. The hard disk drive 70 is housed inside the drawer body 30. The drawer body 30 is housed within the chassis 10. Specifically, the drawer body 30 can be selectively housed within the chassis 10, or the drawer body 30 housed within the chassis 10 can be pulled out of the chassis 10, causing at least a portion of the drawer body 30 to detach from the chassis 10. Pulling the drawer body 30 out of the chassis 10 allows for the replacement or repair of the hard disk drive 70. The telescopic device 50 has a first end 50A and a second end 50B, the second end 50B being connected to the drawer body 30, and the distance between the first end 50A and the second end 50B is variable. By moving at least a portion of the drawer body 30 from inside the chassis 10 to outside the chassis 10, the distance between the first end 50A and the second end 50B of the telescopic device 50 can be changed. Specifically, as... Figure 2 and Figure 3 As shown, the chassis 10 has a retractable end 10A and an open end 10B. When the drawer body 30 is housed within the chassis 10, the first end 50A approaches or abuts against the retractable end 10A of the chassis 10. When a portion of the drawer body 30 detaches from the chassis 10, the first end 50A moves away from the retractable end 10A of the chassis 10 and approaches or abuts against the open end 10B of the chassis 10. Because the second end 50B of the telescopic device 50 is connected to the drawer body 30, pulling the drawer body 30 simultaneously moves the telescopic device 50. The telescopic device 50 is located between the chassis 10 and the drawer body 30.

[0066] like Figure 4 and Figure 5 As shown, the telescopic structure 57 connects the first end 50A and the second end 50B, and the distance between the first end 50A and the second end 50B is changeable. Specifically, the first end 50A can move relative to the second end 50B to change the distance between the first end 50A and the second end 50B. In this embodiment, the server chassis 100 with the telescopic device also includes a fan bracket 92, which is disposed at the first end 50A of the telescopic device 50 and carries the fan module 90. In this embodiment, the telescopic device 50 also includes a roller 59, which is disposed on the fan bracket 92 but is not limited thereto. The telescopic device 50 can move within the chassis 10 via the roller 59. For example, see also... Figure 3 and Figure 4When the drawer body 30 detaches from the chassis 10, the first end 50A of the telescopic device 50 approaches or abuts against the opening end 10B of the chassis 10, and the force provided by the telescopic structure 57 causes the first end 50A to move away from the second end 50B. In this embodiment, the telescopic device 50 also includes a baffle 93, which is disposed at the first end 50A of the telescopic device 50. The chassis 10 includes an opening 11 located at the storage end 10A. When the first end 50A passes through the opening 11, the baffle 93 abuts against the storage end 10A of the chassis 10, causing the first end 50A to approach the second end 50B. For example, the baffle 93 protrudes from the fan bracket 92 at the first end 50A. When the drawer body 30 is pushed back into the chassis 10, part of the fan bracket 92 will pass through the opening 11 on the chassis 10, causing the baffle 93 to abut against the storage end 10A of the chassis 10. The baffle 93 is affected by the abutting force from the storage end 10A and the force of the drawer body 30 being pushed back into the chassis 10, causing the first end 50A to move closer to the second end 50B due to the telescopic structure 57.

[0067] Specifically, the server chassis 100 with the telescopic device 50 can house the hard disk drive 70 within the drawer body 30, and the drawer body 30 is housed within the chassis 10. The second end 50B of the telescopic device 50 is connected to the drawer body 30, and the distance between the first end 50A and the second end 50B is variable. The drawer body 30 can be selectively housed within the chassis 10, or it can be pulled out of the chassis 10. When the drawer body 30 is pulled out, the airflow effect of the fan module 90 is reduced due to the unsealed space, resulting in decreased heat dissipation. At this time, the fan module 90 must increase its speed to stabilize the heat dissipation effect, but as the speed of the fan module 90 increases, the vibration and noise it generates also increase, thereby affecting the read performance of the hard disk drive 70. Therefore, when the drawer body 30 is pulled out, the telescopic device 50 is simultaneously pulled. The telescopic device 50 moves with the drawer body 30, causing the telescopic structure 57 to move its first end 50A relative to its second end 50B, thereby increasing the distance between the fan module 90 and the hard disk drive 70. When the speed of the fan module 90 increases, the increased distance between the fan module 90 and the hard disk drive 70 achieves the effects of vibration reduction and noise reduction.

[0068] In this embodiment, the telescopic device 50 includes a first body 53 and a second body 55. The first body 53 is located at a first end 50A, and the second body 55 is located at a second end 50B. The telescopic structure 57 connects the first body 53 and the second body 55 and provides a force to change the distance between the first body 53 and the second body 55. Figure 5 As shown, the telescopic structure 57 allows for movement of the first body 53 relative to the second body 55 in various embodiments. For example... Figure 5As shown, in this embodiment, the telescopic structure 57 includes a telescopic rod assembly 570, which connects the first body 53 and the second body 55, and provides a force to cause the first body 53 to move relative to the second body 55. For example, please also refer to... Figure 2 and Figure 3 When the drawer body 30 is housed in the chassis 10, the drawer body 30 abuts against the opening end 10B of the chassis 10, causing the drawer body 30 to be squeezed and the telescopic rod assembly 570 to retract. The first body 53 and the second body 55 move closer to each other. When the drawer body 30 is pulled out of the chassis 10 by external force, the force of the opening end 10B of the chassis 10 against the drawer body 30 is released, and the telescopic rod assembly 570 provides a force to move the first body 53 away from the second body 55.

[0069] like Figure 5 As shown, in this embodiment, the telescopic rod assembly 570 is a pneumatic rod, which connects the first body 53 and the second body 55. Figure 4 As shown, due to the limited space inside the chassis 10, the gas spring connects the first body 53 and the second body 55 diagonally in a way that minimizes space usage. However, this is not a limitation; if there is sufficient space in the chassis 10, the gas spring can also connect the first body 53 and the second body 55 horizontally. In this embodiment, the gas spring continuously provides thrust to push the first body 53 away from the second body 55. When the drawer body 30 is housed in the chassis 10, the drawer body 30 is compressed, and the pushing force of the opening end 10B of the chassis 10 on the drawer body 30 causes the gas spring to be compressed. When the drawer body 30 is pulled out of the chassis 10, the gas spring is not limited by the pushing force, allowing the first body 53 to move away from the second body 55.

[0070] like Figure 6As shown, in another embodiment, the telescopic rod assembly 570 consists of a telescopic rod 571 and a spring 572. The spring 572 is located between the first body 53 and the second body 55. The telescopic rod 571 passes through the spring 572. The telescopic rod 571 includes a first end 571a and a second end 571b. The second end 571b is connected to the second body 55, and the first end 571a passes through the first body 53. In this other embodiment, the first end 571a of the telescopic rod 571 passes from the first body 53 to the axial accommodating space 921 of the fan frame 92. When the first body 53 is away from the second body 55, the first end 571a abuts against the first body 53. When the first body 53 is close to the second body 55, the first end 571a abuts against the fan frame 92. In this other embodiment, the telescopic rod 571 passes through the spring 572, and the spring 572 continuously provides elastic force to push the first body 53 away from the second body 55. When the drawer body 30 is housed in the chassis 10, the drawer body 30 is compressed. The pushing force of the opening end 10B of the chassis 10 on the drawer body 30 causes the spring 572 to be compressed. When the drawer body 30 is pulled out of the chassis 10, the spring 572 is no longer restricted by the pushing force, so that the first body 53 is away from the second body 55.

[0071] See again Figure 5Returning to the original embodiment, in this embodiment, the telescopic structure 57 includes a telescopic sleeve 573. The telescopic sleeve 573 connects the first body 53 at the first end 50A and the second body 55 at the second end 50B. The telescopic sleeve 573 has multiple bends 575. When the first body 53 is away from the second body 55, that is, when at least a part of the drawer body 30 is outside the chassis 10, the telescopic sleeve 573 is in an unfolded state, and the multiple bends 575 are unfolded. When the first body 53 is close to the second body 55, that is, when the drawer body 30 is housed inside the chassis 10, the telescopic sleeve 573 is in a retracted state, and the multiple bends 575 are closed. In this embodiment, because the drawer body 30 is not sealed, when the drawer body 30 is detached from the chassis 10, the fan module 90 is driven away from the hard disk drive 70, making it difficult for the airflow from the fan module 90 to reach the hard disk drive 70. To avoid a decrease in heat dissipation efficiency, a telescopic sleeve 573 connects the first body 53 and the second body 55. In other words, the telescopic sleeve 573 seals the airflow from the first body 53 to the second body 55, preventing the airflow from dissipating. In this embodiment, when the telescopic rod assembly 570 changes the distance between the first body 53 and the second body 55, the telescopic sleeve 573 has multiple bends 575 to allow the telescopic sleeve 573 to change length with the telescopic rod assembly 570, enabling the telescopic sleeve 573 to change between an extended and retracted state. When the first body 53 moves away from the second body 55, i.e., the telescopic sleeve 573 is in an extended state, each bend 575 unfolds, causing the telescopic sleeve 573 to lengthen, with each bend 575 unfolding into a slightly V-shape. When the first body 53 approaches the second body 55, that is, when the telescopic sleeve 573 is in a contracted state, each bend 575 bends, causing the telescopic sleeve 573 to shorten.

[0072] like Figure 5As shown, the telescopic device 50 also includes a limiting component 56, which has a continuous cross structure 561. The first body 53 is provided with a first limiting hole 531 and a first pivot hole 532, which are located on opposite sides of the first body 53. The second body 55 is provided with a second limiting hole 551 and a second pivot hole 552, which are located on opposite sides of the second body 55. The continuous cross structure 561 includes two movable parts 562 and two fixed parts 563. The two movable parts 562 are respectively movably inserted through the first limiting hole 531 and the second limiting hole 551, and the two fixed parts 563 are respectively pivotally connected to the first pivot hole 532 and the second pivot hole 552. When the first body 53 moves away from the second body 55, the two movable parts 562 move towards one side of the two fixed parts 563, and the two movable parts 562 respectively abut against one end of the first limiting hole 531 and one end of the second limiting hole 551. When the first body 53 moves closer to the second body 55, the two movable parts 562 move away from one side of the two fixed parts 563, and the two movable parts 562 respectively abut against the other end of the first limiting hole 531 and the other end of the second limiting hole 551. Through this continuous cross structure 561, the maximum extension distance and minimum retraction distance of the telescopic rod assembly 570 can be limited.

[0073] See again Figure 6 In another embodiment, the telescopic structure 57 includes a sliding portion 576 and a sliding part 577. The sliding portion 576 is disposed on the first body 53, and the sliding part 577 is disposed on the second body 55. The sliding portion 576 and the sliding part 577 allow the first body 53 and the second body 55 to be slidably connected to each other. In this other embodiment, the sliding portion 576 is a slide rail, and the sliding part 577 is a slider, but this is not a limitation; the sliding portion 576 can also be a slider, and the sliding part 577 can also be a slide rail. In this other embodiment, the sliding part 577 of the second body 55 engages with the sliding portion 576 of the first body 53, allowing the first body 53 and the second body 55 to slide relative to each other. In this other embodiment, the telescopic structure 57 is a combination of multiple cubes. The relative positions of the first body 53 and the second body 55 can be changed by the sliding part 576 and the sliding part 577. In order to seal the airflow generated by the fan module 90, the second body 55 covers the first body 53, so that the airflow from the first body 53 to the second body 55 is less likely to dissipate, thus preventing the fan module 90 from reducing the heat dissipation of the hard disk device 70.

[0074] See again Figure 2 and Figure 3Returning to the original embodiment, in this embodiment, the telescopic device 50 further includes a driver electrically connected to the telescopic rod assembly 570. The chassis 10 also includes a sensor 12, which is signal-connected to the driver. When the sensor 12 senses a signal and transmits it to the driver, the driver causes the telescopic rod assembly 570 to actuate, causing the first body 53 to move relative to the second body 55. In this embodiment, the telescopic rod assembly 570 is an electric pneumatic rod, whose extension and retraction are controlled by signals. When the sensor 12 detects that the drawer body 30 is detaching from the chassis 10, the sensor 12 transmits a signal to the driver, which drives the telescopic rod assembly 570 to move the first body 53 away from the second body 55. When the sensor 12 detects that the drawer body 30 is retracting into the chassis 10, the sensor 12 transmits a signal to the driver, which drives the telescopic rod assembly 570 to move the first body 53 closer to the second body 55.

[0075] Please see Figure 7 In this embodiment, the telescopic device 50 further includes a storage structure 54 disposed between the first end 50A and the second end 50B. When the first end 50A moves relative to the second end 50B, the shape of the storage structure 54 changes accordingly. In this embodiment, the storage structure 54 can store the cables used by the telescopic device 50, such as power cables and signal cables. Specifically, when the first end 50A moves away from the second end 50B, the storage structure 54 is stretched and unfolded. When the first end 50A moves closer to the second end 50B, the storage structure 54 is compressed and bent, and the cables are stored within the storage structure 54, preventing the cables from becoming tangled as the device moves between the first end 50A and the second end 50B.

[0076] The storage structure 54 has several implementations. In this embodiment, the storage structure 54 comprises multiple housings 541 pivotally connected to each other. In this embodiment, each housing 541 pivots relative to each other as the first end 50A and the second end 50B move. When the first end 50A approaches the second end 50B, each housing 541 pivots relative to each other and forms a slightly V-shape. When the first end 50A moves away from the second end 50B, each housing 541 pivots relative to each other and forms a slightly arched shape. In another embodiment, the storage structure 54 is a flexible tube. When the first end 50A approaches the second end 50B, the flexible tube bends and forms a slightly V-shape. When the first end 50A moves away from the second end 50B, the flexible tube is stretched and forms a slightly arched shape.

[0077] See again Figure 1 , Figure 2 and Figure 3According to one embodiment, a server with a telescopic device is provided. The structure of the server with the telescopic device is the same as that of the server chassis 100 and will not be described again. The server with the telescopic device includes a chassis 10, a drawer body 30, a telescopic device 50, a hard disk assembly 70, and a fan module 90. The drawer body 30 is housed within the chassis 10. The telescopic device 50 has a first end 50A, a second end 50B, and a telescopic structure 57. The second end 50B is connected to the drawer body 30, and the telescopic structure 57 connects the first end 50A and the second end 50B, making the distance between the first end 50A and the second end 50B variable. The hard disk assembly 70 is assembled within the drawer body 30. The fan module 90 is disposed at the first end 50A of the telescopic device 50. By moving at least a portion of the drawer body 30 from within the chassis 10 to outside the chassis 10, the distance between the first end 50A and the second end 50B of the telescopic device 50 can be changed.

[0078] In summary, the server chassis 100 with telescopic device 50 in this case has its drawer body 30 housed within the chassis 10. The second end 50B of the telescopic device 50 is connected to the drawer body 30, and the distance between the first end 50A and the second end 50B is variable. The drawer body 30 can be selectively housed within the chassis 10, or it can be pulled out of the chassis 10. When the drawer body 30 is pulled out, the airflow effect of the fan module 90 is reduced due to the unsealed space, resulting in decreased heat dissipation. At this time, the fan module 90 must increase its speed to stabilize the heat dissipation effect, but as the speed of the fan module 90 increases, the vibration and noise it generates also increase, thereby affecting the read performance of the hard disk drive 70. Therefore, when the drawer body 30 is pulled out, the telescopic device 50 is simultaneously pulled. The telescopic device 50 moves with the drawer body 30, causing the telescopic structure 57 to move the first body 53 at the first end 50A relative to the second body 55 at the second end 50B, thereby increasing the distance between the fan module 90 and the hard disk drive 70. When the speed of the fan module 90 increases, the increased distance between the fan module 90 and the hard disk drive 70 achieves the effects of vibration reduction and noise reduction.
