Server equipment and its tray mechanism

Abstract

This invention discloses a server device and its tray mechanism, wherein the server device includes a carrier housing, a tray mechanism comprising a tray, a handle, and a spring, and a server module disposed on the tray. The carrier housing has a first engaging structure and a first protruding structure. The handle is pivotally connected to the tray. The spring is connected to the tray and has a second protruding structure that can protrude through the tray and an interference structure. The interference structure interferes with the handle to hold the handle in an unlocked position, and such that the handle does not interfere with the first engaging structure when the tray is inserted into the carrier housing in the insertion direction. When the tray is inserted into the carrier housing and the first protruding structure pushes against the second protruding structure, the interference structure moves without interfering with the handle, so that the handle can be rotated to a mounting position to engage the first engaging structure.

Description

Technical Field

[0001] This invention relates to a server device and its tray mechanism, and more particularly to a server device and its tray mechanism that uses a spring-loaded interference handle for handle positioning. Background Technology

[0002] Generally speaking, in terms of server component assembly, the server modules (including server-related components such as graphics cards and server motherboards) are usually installed on a tray first. Then, the tray with the integrated server modules is inserted into the server chassis through the front opening of the chassis. This allows for a quick and convenient completion of the server component assembly process.

[0003] Existing technology typically uses a snap-fit ​​design where the snap-fit ​​handle at the front of the tray is attached to a snap-fit ​​structure located on the side panel of the chassis to fix the tray to the server chassis and to drive the server module to connect to the internal ports of the server chassis. However, during the assembly process when the user pushes the snap-fit ​​handle to insert the tray into the server chassis, it is not possible to reliably keep the snap-fit ​​handle above the snap-fit ​​structure. As a result, the snap-fit ​​handle often hits the snap-fit ​​structure, which can lead to component damage or even interference and jamming. Summary of the Invention

[0004] One of the objectives of this invention is to provide a server device and its tray mechanism that use a spring-loaded interference handle for handle positioning, in order to solve the above-mentioned problems.

[0005] According to one embodiment, the server device of the present invention includes a carrier housing, a tray mechanism, and at least one server module. The carrier housing forms a first engaging structure and a first protruding structure. The tray mechanism includes a tray, a handle, and a spring. The tray has a first side plate. The handle has at least one pivot portion pivotally connected to the first side plate to deflect the handle relative to the tray between a release position and a mounting position. The spring is connected to the first side plate and has a second protruding structure that protrudes through the first side plate and at least one interference structure that interferes with the pivot portion to hold the handle in the release position, and such that the pivot portion and the first engaging structure do not interfere when the tray is inserted into the carrier housing in an insertion direction. The at least one server module is disposed on the tray. When the tray is inserted into the carrier housing and the first protruding structure pushes against the second protruding structure, the interference structure moves relative to the first side plate without interfering with the pivot portion, so that the handle can be rotated to the mounting position to engage the first engaging structure.

[0006] According to another embodiment, the tray mechanism of the present invention is suitable for assembling at least one electronic module with a carrier housing, the carrier housing forming a first engaging structure and a first protruding structure. The tray mechanism includes a tray, a handle, and a spring. The tray has a first side plate, on which the at least one electronic module is disposed. The handle has at least one pivot portion pivotally connected to the first side plate to deflect the handle relative to the tray between a release position and an installation position. The spring is connected to the first side plate and has a second protruding structure that can protrude through the first side plate and at least one interference structure that interferes with the pivot portion to hold the handle in the release position and such that the pivot portion and the first engaging structure do not interfere when the tray is inserted into the carrier housing in an insertion direction. When the tray is inserted into the carrier housing and the first protruding structure pushes against the second protruding structure, the interference structure moves relative to the first side plate without interfering with the pivot portion, so that the handle can be rotated to the installation position to engage the first engaging structure.

[0007] In summary, by using the interference structure on the spring to interfere with the pivot of the handle to position the handle in the unlocking position, the present invention ensures that the handle of the pallet mechanism does not interfere with the first engagement structure of the carrier housing during the process of inserting the pallet into the carrier housing. In this way, the present invention can solve the problem mentioned in the prior art that the pallet's latching handle will hit the latching structure of the carrier housing during the pallet assembly process, resulting in component damage or even interference and jamming, thereby effectively improving the service life and operational convenience of the pallet mechanism.

[0043] Please see Figure 1 as well as Figure 2 , Figure 1 This is a partially exploded view of a server device 10 according to an embodiment of the present invention. Figure 2 for Figure 1 A partial side view of a tray mechanism 14, wherein a carrier housing 12 is provided to clearly show the internal component structure of the server device 10. Figure 2 The diagram only uses a single first engagement structure 20 for simplification. For example... Figure 1 as well as Figure 2 As shown, the server device 10 includes a housing 12, a tray mechanism 14, and at least one server module 16 (in...). Figure 1 (Only one is shown in the figure and is simplified with a dashed line, but this is not a limitation). That is to say, the tray mechanism 14 provided by the present invention is preferably applicable to the assembly of server module 16 and carrier housing 12, but is not limited thereto. In another embodiment, the tray mechanism 14 can also be applied to the assembly of carrier housing 12 and other electronic modules (such as disk arrays). The relevant description can be deduced by referring to the following figures and descriptions, and will not be repeated here.

[0044] For example, the fixing design of the tray mechanism 14 can be better applied to both side partitions of the carrier housing 12 to install the server module 16 into the carrier housing 12 with ease and stability (but it is not limited to this, it can also be applied to only one side partition of the carrier housing 12 to simplify the mechanism design of the server device 10). For the sake of simplicity, the following description only focuses on the fixing design between one of the second side plates 18 on the carrier housing 12 and the tray mechanism 14. As for the fixing design between the other second side plate 18 and the tray mechanism 14, the relevant description can be deduced from the following description, and will not be repeated here.

[0045] Depend on Figure 1 as well as Figure 2It is understood that the first engaging structure 20 and the first protruding structure 22 are preferably formed on the second side plate 18 of the carrier housing 12. The tray mechanism 14 includes a tray 24, a handle 26, and a spring 28. The server module 16 is disposed on the tray 24 and installed in the carrier housing 12 via the support of the tray 24. The handle 26 has a pivot portion 30, which is pivotally connected to a first side plate 25 of the tray 24 corresponding to the second side plate 18 so that the handle 26 can deflect relative to the tray 24 between an unlocked position and an installed position. The pivot portion 30 may preferably have a second engaging structure 32 (but is not limited thereto). The spring 28 may preferably be connected to the first side plate 25 by means of riveting, rivet fixing, or screw locking (but is not limited thereto) and has a second protruding structure 34 that can protrude through the first side plate 25 and an interference structure 36, wherein the first protruding structure 22 is self-supporting. The second side plate 18 of the housing 12 is recessed inward, and the second protruding structure 34 is recessed outward from the spring piece 28 so as to interfere with the first protruding structure 22. The first engaging structure 20 is preferably a positioning post, and the second engaging structure 32 is preferably a hook-and-loop notch. The interference structure 36 is preferably a protruding post that abuts against a flange 33 of the second engaging structure 32 to produce a positioning effect. More specifically, in this embodiment, the flange 33 may extend to form a limiting notch 38 (but is not limited to this, it may also be designed with only the interference structure 36 abutting against the flange 33). Thus, the interference structure 36 can engage with the limiting notch 38 to securely position the handle 26 in the unlocked position.

[0046] It should be noted that the structural interference design used in this invention is not limited to the design of using a single interference structure to interfere with the pivot portion mentioned in the above embodiments. It can also employ a multi-point interference design. For example, in another embodiment, the interference structure 36 can be formed on both sides of the pivot point of the spring piece 28 corresponding to the pivot portion 30, to stop the pivot portion 30 from rotating clockwise and counterclockwise, thereby achieving the purpose of stably positioning the handle 26 in the unlocked position. Furthermore, in practical applications, a limiting pin 40 protrudes from the first side plate 25, and an arc-shaped groove 42 is formed on the pivot portion 30 corresponding to the limiting pin 40. Thus, the limiting pin 40 can pass through the arc-shaped groove 42 to limit the rotation range of the handle 26, thereby effectively preventing damage to components or interference jamming caused by excessive deflection of the handle 26 during operation.

[0047] The following is a detailed description of the operation of pallet mechanism 14. Please refer to [link / reference]. Figure 2 , Figure 3 , Figure 4 , Figure 5 ,as well as Figure 6 , Figure 3 for Figure 2A partial cross-sectional view of the pallet mechanism 14 along section line AA. Figure 4 for Figure 2 A partial side view of the tray mechanism 14 when the handle 26 is rotated to the unlocked position. Figure 5 A partial side view of the pallet mechanism 14 inserted into the carrier housing 12 along the insertion direction I. Figure 6 for Figure 2 A three-dimensional schematic diagram of the tray mechanism 14 inserted into the carrier housing 12. First, when the handle 26 is in the position as shown... Figure 2 In the installation position shown, the second engaging structure 32 can engage with the first engaging structure 20, so that the tray mechanism 14 can be securely inserted into the carrier housing 12. At this time, by Figure 3 It is understood that the first protruding structure 22 can push against the second protruding structure 34 to cause the spring piece 28 to flex elastically, so that the interference structure 36 can move relative to the first side plate 25 without interfering with the pivot part 30, thereby allowing the handle 26 to rotate between the mounting position and the unlocking position.

[0048] On the other hand, when the user wants to pull out the tray mechanism 14, the user only needs to pull the handle 26 from the tray. Figure 2 Rotate to the installation position shown. Figure 4 In the unlocking position shown, during this process, the second engaging structure 32 can move and rotate against the first engaging structure 20, pushing the tray 24 in the opposite direction to the insertion direction I. Next, since the second engaging structure 32 no longer engages the first engaging structure 20, the user can pull the handle 26 to pull the tray 24 outwards. This causes the second protruding structure 34 to no longer interfere with the first protruding structure 22 as the tray 24 moves outwards relative to the housing 12. Consequently, the interference structure 36 can protrude outwards through the first side plate 25 to engage with the limiting recess 38, thus securing the handle 26 in the unlocking position. Finally, the user can continue to pull the handle 26 to remove the tray mechanism 14, which houses the server module 16, from the housing 12 for subsequent replacement or repair of the server module 16.

[0049] Conversely, when the user wants to assemble the tray mechanism 14, the user only needs to push the handle 26 (at this time, as mentioned above, the interference structure 36 engages with the limiting recess 38 to securely position the handle 26 in the unlocked position) to insert the tray mechanism 14 into the carrier housing 12 along the insertion direction I. During this process, by Figure 5It is understood that the second engaging structure 32 and the first engaging structure 20 are offset from each other and do not interfere (in this embodiment, this means that the position height of the flange 33 of the second engaging structure 32 is higher than the position height of the first engaging structure 20). Therefore, the present invention ensures that the second engaging structure 32 will not collide with the first engaging structure 20 during the insertion of the tray mechanism 14 into the carrier housing 12 along the insertion direction I, thereby allowing the user to smoothly insert the tray mechanism 14 into the housing 12 along the insertion direction I. Figure 4 At the position shown, at this time, as Figure 3 As shown, since the first protruding structure 22 has interfered with the second protruding structure 34, causing the spring piece 28 to elastically flex, the interfering structure 36 can move relative to the first side plate 25 without interfering with the pivot portion 30. Next, the user can move the handle 26 from... Figure 4 Rotate to the unlock position shown. Figure 2 The installation position shown allows the second engaging structure 32 to rotate and engage with the first engaging structure 20, for securely inserting the pallet mechanism 14 into the carrier housing 12 (e.g., Figure 6 (as shown), thereby completing the assembly operation of the tray mechanism 14.

[0050] In summary, by using the interference structure on the spring to interfere with the pivot of the handle to position the handle in the unlocking position, the present invention ensures that the handle of the pallet mechanism does not interfere with the first engagement structure of the carrier housing during the process of inserting the pallet into the carrier housing. In this way, the present invention can solve the problem mentioned in the prior art that the pallet's latching handle will hit the latching structure of the carrier housing during the pallet assembly process, resulting in component damage or even interference and jamming, thereby effectively improving the service life and operational convenience of the pallet mechanism.

[0051] It is worth mentioning that the handle configuration of the present invention is not limited to the design of pivoting the handle's pivot portion to the side partition of the carrier housing as used in the above embodiments. It can also be modified to use a design where the handle's pivot portion is pivotally connected to the bottom plate of the carrier housing. For example, please refer to... Figure 7 , Figure 8 , Figure 9 ,as well as Figure 10 , Figure 7 This is a partially exploded view of a server device 100 according to another embodiment of the present invention. Figure 8 for Figure 7 A partial perspective view of a pallet mechanism 104 inserted into a carrier housing 102. Figure 9 for Figure 7 A simplified internal diagram of server device 100. Figure 10 for Figure 9 A partial top view of server device 100, wherein, in order to clearly show the internal component structure of server device 100, in Figure 9 The illustration of tray 110 is omitted here. Components with the same number as those mentioned in the above embodiments are considered to have the same structure or function, and their related descriptions will not be repeated here.

[0052] like Figure 7 , Figure 8 , Figure 9 ,as well as Figure 10 As shown, the server device 100 includes a housing 102, a tray mechanism 104, and at least one server module 16 (in...). Figure 7 (Only one is shown in the image and is simplified with dashed lines, but this is not a limitation). A second side plate 106 of the carrier housing 102 may be a base plate and may have a first engaging structure 108 and a first protruding structure 22. The tray mechanism 104 includes a tray 110, a handle 112, and a spring 114. The server module 16 is disposed on the tray 110 for mounting in the carrier housing 102 via the support of the tray 110. The handle 112 has a pivot portion 116, which is pivotally connected to a first side plate 111 of the tray 110 corresponding to the second side plate 106, so that the handle 112 can deflect relative to the tray 110 between an unlocked position and an installed position. The pivot portion 116 may have a second engaging structure 120. The spring 114 may preferably be connected to the first side plate 111 by means of riveting, rivet fixing, or screw locking (but is not limited to this) and has a protrusion through the first side plate 111. The second protruding structure 34 and the interference structure 122 are provided. The first protruding structure 22 can be formed by recessing the second side plate 106 of the supporting housing 102 inward. The second protruding structure 34 can be formed by recessing the spring piece 114 outward so as to interfere with the first protruding structure 22. The first engaging structure 108 can preferably be a positioning groove. The second engaging structure 120 can preferably be a positioning hook. The interference structure 122 can preferably be formed by drawing and protruding (but not limited to) a protrusion on the spring piece 114 and pass through an interference hole 124 in the pivot portion 116 to produce a handle positioning function.

[0053] The following is a detailed description of the operation of pallet mechanism 104. Please refer to [link / reference]. Figure 8 , Figure 9 , Figure 10 , Figure 11 ,as well as Figure 12 , Figure 11 for Figure 10 A partial cross-sectional view of the pallet mechanism 104 along section line BB. Figure 12 for Figure 10 The tray mechanism 14 is partially viewed from above when the handle 112 is rotated to the unlocked position. Firstly, when the handle 112 is in the position as shown... Figure 9In the installation position shown, the second engaging structure 120 can engage with the first engaging structure 108, allowing the tray mechanism 104 to be securely inserted into the carrier housing 102. At this time, the... Figure 11 It is understood that the first protruding structure 22 can push against the second protruding structure 34 to cause the spring piece 114 to flex elastically, so that the interference structure 122 can move without interfering with the pivot part 116, thereby allowing the handle 112 to rotate between the installed position and the unlocked position.

[0054] On the other hand, when the user wants to pull out the tray mechanism 104, the user only needs to pull the handle 112 from the tray. Figure 10 Rotate to the installation position shown. Figure 12 The unlocking position shown releases the engagement between the second engaging structure 120 and the first engaging structure 108. Since the second engaging structure 120 no longer hooks onto the first engaging structure 108, the user can pull the handle 112 to pull the tray 110 outwards. This causes the second protruding structure 34 to no longer interfere with the first protruding structure 22 as the tray 110 moves outwards relative to the housing 102. Consequently, the interference structure 122 can protrude outwards through the first side plate 111 to engage with the interference hole 124, thus securing the handle 112 in the unlocking position. Finally, the user can continue to pull the handle 112 to remove the tray mechanism 104, which houses the server module 16, from the housing 102 for subsequent replacement or repair of the server module 16.

[0055] Conversely, when the user wants to assemble the tray mechanism 104, the user only needs to push the handle 112 (at this time, as mentioned above, the interference structure 122 engages with the interference hole 124 to securely position the handle 112 in the unlocked position) to insert the tray mechanism 104 into the carrier housing 102 along the insertion direction I. During this process, by Figure 12 It is known that the second engaging structure 120 does not interfere with the first engaging structure 108. Therefore, the present invention ensures that the second engaging structure 120 will not collide with the first engaging structure 108 during the insertion of the tray mechanism 104 along the insertion direction I into the carrier housing 102, thereby allowing the user to smoothly insert the tray mechanism 104 along the insertion direction I into the housing. Figure 12 At the position shown, at this time, as Figure 11 As shown, since the first protruding structure 22 has pushed against the second protruding structure 34, causing the spring piece 114 to elastically flex, the interference structure 122 can move relative to the first side plate 111 without interfering with the pivot portion 116. Next, the user can move the handle 112 from... Figure 12 Rotate to the unlock position shown. Figure 10The installation position shown allows the second engaging structure 120 to rotate and engage with the first engaging structure 108, for securely inserting the pallet mechanism 104 into the carrier housing 102 (e.g., Figure 8 (as shown), thereby completing the assembly operation of the tray mechanism 104.

[0056] It should be noted that the interference structure design adopted by the tray mechanism 104 is not limited to the above-mentioned design of using a protruding post to pass through the interference hole. It can also be replaced by a design of a tongue inserted into the positioning groove. In short, in another embodiment, the interference structure can be a tongue formed on the spring by stamping and bending (but not limited to this), and the pivot part has an interference groove formed at the position of the tongue. Thus, the tongue can be inserted into the interference groove to stop the rotation of the handle in the clockwise and counterclockwise directions. In addition, the interference structure design (such as the design of the protrusion engaging with the limiting notch, the protrusion passing through the interference hole, and the design of the tongue being inserted into the positioning groove) and the engagement structure design (such as the design of the hook notch rotating to engage the positioning post and the design of the positioning hook engaging the positioning groove) mentioned in the above embodiments can be applied to each other to improve the design flexibility of the pallet mechanism of the present invention in terms of structural interference engagement. The relevant descriptions of the derivative embodiments can be deduced by analogy with the above embodiments and will not be repeated here. As for which design is adopted, it depends on the actual application of the pallet mechanism of the present invention and is not limited to the above embodiments.

[0057] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made in accordance with the claims of the present invention should be included within the scope of the present invention.
