Description

TECHNICAL FIELD

[0001] The application relates to a case and a server. BACKGROUND

[0002] At present, for such a product as a server with more stringent space requirements, a simple and compact structure is particularly important. For a case containing two node trays on the left and right, it is necessary to ensure that when one side tray is pulled out, the self-locking of the other side tray cannot be pulled out, so as to reduce misoperation. At present, the server cases containing two trays on the market all adopt a self-locking structure occupying a large space. However, due to the limited space of the server case, the self-locking structure will affect the volume of the tray, and there is a problem of reducing the space utilization of the server case, which affects the overall planning of the server. SUMMARY

[0003] Therefore, it is necessary to provide a case capable of improving space utilization and having a self-locking function and a server having the same.

[0004] In an embodiment of the application, a case is provided, which comprises a shell, a tray, an elastic member and a limiting member. The shell is provided with an opening. Two trays are arranged side by side and can be respectively slid out of or retracted into the shell through the opening. Each tray is used for carrying a plurality of devices. The elastic member is fixedly connected to one end of the shell near the opening and located between the two trays. The limiting member is connected to the elastic member and located between the two trays. The two trays are respectively provided with a socket corresponding to the limiting member, and the inner ends of the two trays are respectively provided with a protrusion. After one tray is slid out of the opening, the protrusion can slide to the limiting member and push the limiting member into the socket of the other tray to limit the movement of the other tray. After one tray is retracted into the shell, the protrusion is separated from the limiting member, and the elastic member can elastically reset the limiting member so that the limiting member is separated from the socket.

[0005] The case can realize the purpose of having a self-locking function and improving space utilization by the protrusion sliding to the limiting member and pushing the limiting member into the socket of the other tray to limit the movement of the other tray after the tray is slid out of the opening, and the protrusion being separated from the limiting member and the elastic member elastically resetting the limiting member so that the limiting member is separated from the socket after the tray is retracted into the shell.

[0006] In some embodiments, the shell comprises a partition plate. The two partition plates are located between the two trays, and a gap is provided between the two partition plates for accommodating the elastic member and the limiting member. The two partition plates are respectively provided with a through hole, and the two ends of the limiting member pass through the through holes respectively.

[0007] In some embodiments, the protrusion includes a connected inclined surface and a flat surface, the inclined surface being disposed toward the limiting member, the flat surface being parallel to the sliding direction of the tray, the inclined surface slidingly contacting the limiting member to push the limiting member into the insertion hole until the limiting member contacts the flat surface, the flat surface being used to keep the limiting member within the insertion hole to prevent jamming.

[0008] In some embodiments, the limiting member has chamfers or rounded corners at both ends to reduce friction between the limiting member and the inclined surface and the plane, so as to prevent jamming.

[0009] In some embodiments, the distance between one end of the limiting member and the adjacent insertion hole is less than half the height value of the protrusion, so that the protrusion can push the limiting member into the insertion hole.

[0010] In some embodiments, at least two of the limiting member and the insertion hole are provided respectively to improve the stability of the tray limiting.

[0011] In some embodiments, the limiting member includes a coaxial column and a disc, the disc being located at the center of the column and placed between the two partitions, the two elastic members being respectively located between one of the partitions and the disc, the two ends of the column being used to insert into the insertion hole, and the two elastic members being used to elastically reset the column by pushing against the disc.

[0012] In some embodiments, the tray includes a bottom wall, a top wall, an inner side wall, and an outer side wall. The top wall is located above the bottom wall. The space between the bottom wall and the top wall is used to install a plurality of the devices. The inner side wall and the outer side wall connect the edges of the top wall and the bottom wall, and the outer side wall is located at the outer end of the tray. The inner side wall is close to the inner end of the tray. The insertion hole is provided on the outer side wall, and the protrusion is provided on the inner side wall.

[0013] In some embodiments, the housing includes a lower shell and an upper shell, the lower shell being used to support the two trays, one side of the tray being slidably connected to the folded edge of the lower shell, and the upper shell being used to cover the two trays to protect them.

[0014] One embodiment of this application also provides a server, including the aforementioned chassis. The server, through the aforementioned chassis, also achieves the purpose of having a self-locking function while simultaneously improving space utilization. Attached Figure Description

[0043] The technical solution of this application will now be described with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0044] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0046] One embodiment of this application provides a chassis, including a shell, a tray, an elastic element, and a limiting element. The shell has an opening, and two trays are arranged side by side, each capable of sliding out of or retracting from the shell through the opening. Each tray carries multiple devices. The elastic element is fixedly connected to one end of the shell near the opening and located between the two trays. The limiting element is connected to the elastic element and located between the two trays. Each tray has an insertion hole corresponding to the limiting element, and the inner ends of the two trays have protrusions facing each other. After one tray slides out of the opening, the protrusion can slide to the limiting element and push the limiting element to insert into the insertion hole of the other tray, thereby restricting the movement of the other tray. After one tray retracts into the shell, the protrusion disengages from the limiting element, and the elastic element can elastically reset the limiting element, causing the limiting element to disengage from the insertion hole.

[0047] After the aforementioned chassis slides out of the opening via the tray, the protrusion can slide to the limiting member and push the limiting member into the insertion hole of another tray to restrict the movement of the other tray. After the tray retracts into the housing, the protrusion disengages from the limiting member, and the elastic member elastically resets the limiting member to disengage from the insertion hole, thus achieving the purpose of having a self-locking function and improving space utilization.

[0048] One embodiment of this application also provides a server, including the aforementioned chassis. The server, through the aforementioned chassis, also achieves the purpose of having a self-locking function while simultaneously improving space utilization.

[0049] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0050] Please see Figure 1 , Figure 2 and Figure 3 This application provides a chassis 100 for mounting electronic devices 200 and having a self-locking function. The chassis 100 includes a shell 10, trays 20, elastic members 30, and limiting members 40. The shell 10 is generally cubical, with an internal receiving cavity and an opening at one end. Two trays 20 are provided and arranged side by side in a horizontal direction. The two trays 20 can be independently slid out of or retracted into the receiving cavity of the shell 10 through the opening. Each tray 20 is used to carry multiple devices 200. The elastic member 30 is fixedly connected to the end of the shell 10 near the opening and is located between the two trays 20. The limiting member 40 is connected to the elastic member 30 and is also located between the two trays 20. The two trays 20 are respectively provided with insertion holes 21 corresponding to the positions of the limiting members 40, and the two trays 20 are respectively provided with protrusions 22 facing each other at the inner ends of the receiving cavity of the shell 10.

[0051] One embodiment of the self-locking mechanism of the chassis 100 is as follows: after one tray 20 slides out of the opening and to its maximum extent, the protrusion 22 of the tray 20 will slide to the limiting member 40 and push against the limiting member 40 to insert into the insertion hole 21 of the other tray 20 on the opposite side (e.g., Figure 3 As shown), this restricts the movement of the opposite tray 20, i.e., locks the opposite tray 20; and after the tray 20 retracts into the housing 10, the protrusion disengages from the limiting member 40, and the elastic member 30 can elastically reset the limiting member 40, thereby disengaging the limiting member 40 from the insertion hole 21, and thus unlocking the opposite tray 20 (as shown). Figure 2 As shown in the diagram, the chassis 100 achieves the purpose of locking the opposite tray 20 when either of the two trays 20 is pulled out of the housing 10, thereby preventing accidental operation. As an example, the device 200 is a hard disk.

[0052] Please see Figure 1, in some embodiments, the housing 10 includes two partition plates 11. The two partition plates 11 are located between the two trays 20 and are vertically arranged, extending parallel to the sliding direction of the trays 20. A gap 11a is provided between the two partition plates 11. The gap 11a is used to accommodate the elastic member 30 and the limiting member 40. Through holes (not shown in the figure) are respectively provided corresponding to the two partition plates 11. Both ends of the limiting member 40 pass through the through holes on both sides, thereby allowing both ends of the limiting member 40 to be inserted into the insertion holes 21. As an exemplary example, the limiting member 40 is a pin.

[0053] Please refer to Figure 2 and Figure 3 , in some embodiments, the protrusion 22 includes a connected inclined surface 22a and a flat surface 22b. The inclined surface 22a is vertically arranged and faces the limiting member 40. The flat surface 22b is vertically arranged and extends along a direction parallel to the sliding direction of the tray 20. During the process of the tray 20 sliding out of the opening, the inclined surface 22a will first slide into contact with one end of the limiting member 40 and gradually push the limiting member 40 to move, making the other end of it gradually inserted into the insertion hole 21 on the opposite side. Until the tray 20 slides out of the opening to the maximum extent, the limiting member 40 contacts the flat surface 22b at this time. The flat surface 22b is used to maintain the position of the limiting member 40, so that one end of it is always located within the insertion hole 21. When the tray 20 retracts into the opening, the flat surface 22b and the inclined surface 22a gradually move away from the limiting member 40, and the elastic member 30 pushes the limiting member 40 to reset. It can be understood that the function of the inclined surface 22a is to facilitate the protrusion 22 to push the limiting member 40 and prevent jamming.

[0054] Further, in some embodiments, the cross-section of the limiting member 40 is circular, and chamfers or rounded corners are provided at both ends respectively to reduce the friction between the limiting member 40 and the inclined surface 22a and the flat surface 22b, thereby preventing jamming.

[0055] Please refer to Figure 4 , in some embodiments, in the state where the tray 20 retracts into the opening, the two trays 20 and the limiting member 40 are symmetrically arranged with respect to the central cross-section of the limiting member 40. The distance between one end of the limiting member 40 and the tray 20 close to this end is L1, that is, L1 is also the distance between one end of the limiting member 40 and the insertion hole 21 close to this end. The maximum height value of the protrusion 22 is L2. It is necessary to satisfy L1 < L2 so that the protrusion 22 can push the limiting member 40 to move, otherwise the protrusion 22 cannot contact the limiting member 40.

[0056] Furthermore, along the axial direction of the limiting member 40, the distance between one end of the limiting member 40 and the maximum height of the protrusion 22 is L3, and it can be understood that L3 = L2 - L1. L3 > L1 must be satisfied so that the protrusion 22 can push the limiting member 40 into the insertion hole 21; otherwise, the distance by which the protrusion 22 pushes against the limiting member 40 is insufficient for insertion into the insertion hole 21. Since L3 = L2 - L1 > L1, we can conclude that L2 / 2 > L1, meaning L1 needs to be less than half of L2.

[0057] Please see Figure 1 In some embodiments, two limiting members 40 and two insertion holes 21 are respectively provided on the top and bottom, and two protrusions 22 are also provided accordingly to improve the stability of the tray 20. In other embodiments, other quantities of limiting members 40, insertion holes 21, and protrusions 22 may also be provided.

[0058] Please see Figure 5 In some embodiments, the limiting member 40 includes a column 41 and a disc 42 coaxially connected. The disc 42 is located at the center of the column 41 and positioned between two partitions 11. Two elastic members 30 are respectively located between one partition 11 and the disc 42, i.e., there is an elastic member 30 on each side of the disc 42. The two ends of the column 41 are used for insertion into the insertion hole 21. The two elastic members 30 push against the disc 42 to elastically reset the column 41 and disengage it from the insertion hole 21. As an exemplary example, the elastic member 30 is a spring.

[0059] Please see Figure 6 In some embodiments, the tray 20 includes a bottom wall 23, a top wall 24, an inner side wall (not shown), and an outer side wall 25. The top wall 24 is located above the bottom wall 23, and the space between the bottom wall 23 and the top wall 24 is used to install multiple devices 200, which are installed to the tray 20 by lateral plug-in. The inner side wall and the outer side wall 25 are connected to the edges of the top wall 24 and the bottom wall 23, with the outer side wall 25 located at the outer end of the tray 20 and the inner side wall near the inner end of the tray. A socket 21 is provided on the outer side wall 25, and a protrusion 22 is provided on the inner side wall. The outer side wall 25 is also provided with a handle 25a for operating the extension and retraction of the tray 20.

[0060] Please see Figure 7 The housing 10 also includes a lower housing 12 and an upper housing 13. The lower housing 12 is used to support two trays 20. One side of the tray 20 is slidably connected to the folded edge of the lower housing 12 via a slide rail, and the other side is slidably connected to the partition 11 via a slide rail. The upper housing 13 is used to cover the two trays 20 for protection.

[0061] One embodiment of this application provides a server (not shown), including a chassis 100.

[0062] After the aforementioned chassis 100 slides out of the opening via the tray 20, the protrusion 22 can slide to the limiting member 40 and push the limiting member 40 into the insertion hole 21 of another tray 20, thereby restricting the movement of the other tray 20. When the tray 20 retracts into the housing 10, the protrusion 22 disengages from the limiting member 40, and the elastic member 30 elastically resets the limiting member 40, causing the limiting member 40 to disengage from the insertion hole 21. This achieves a self-locking function while simultaneously improving space utilization. The aforementioned server, through the aforementioned chassis 100, also achieves a self-locking function while simultaneously improving space utilization.

[0063] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
