Description

Technical Field

[0001] The invention relates to a tray and an electronic device having the tray. Background Art

[0002] Large servers in general communications and data centers can be cabinet-type. The cabinet can be equipped with a chassis to expand the server hardware equipment according to user needs. At this time, the connector of the chassis is docked with the connector of the cabinet. However, in the process of docking the chassis with the cabinet, an external force of 150N is required to dock the connector of the chassis with the connector of the cabinet. On the contrary, when the chassis is unfastened from the cabinet, a reaction force of 150N will also be generated. Therefore, if the chassis is equipped with an auxiliary handle, the reaction force generated at the moment the chassis is unfastened from the cabinet will pop out the auxiliary handle, causing injury to the operator. Furthermore, there is a gap between the auxiliary handle and the chassis to accommodate parts, and the auxiliary handle is easy to shake during operation, and the operator needs to apply more force to stabilize the handle. Summary of the invention

[0003] In view of the above problems, an object of the embodiments of the present invention is to provide a tray and an electronic device.

[0004] According to some embodiments, a tray is provided, which includes a bottom plate, a mounting plate, a handle, and a spring sheet, wherein the mounting plate is disposed on the bottom plate, the mounting plate includes a first buckle hole and a second buckle hole, and the handle is pivotally disposed on the bottom plate and located between the mounting plate and the bottom plate. In addition, the spring sheet is disposed on the handle, and the spring sheet includes a first protrusion, the first protrusion protrudes toward the mounting plate, and the first protrusion is suitable for selectively being located in the first buckle hole or the second buckle hole.

[0005] According to some embodiments, an electronic device is provided, including a cabinet and a chassis, wherein the chassis is accommodated in the cabinet, the chassis includes a chassis, a mounting plate, a handle, and a spring, wherein the mounting plate is disposed on the chassis, the mounting plate includes a first buckle hole and a second buckle hole, the handle is pivotally disposed on the chassis, and the handle is located between the mounting plate and the chassis. In addition, the spring is disposed on the handle, the spring includes a first protrusion, the first protrusion protrudes toward the mounting plate, and the first protrusion is suitable for selectively being located in the first buckle hole or the second buckle hole.

[0006] In summary, according to some embodiments, by providing a spring sheet on the handle, the spring sheet selectively engages with the first buckle hole or the second buckle hole of the mounting plate, and the spring sheet can reduce the ejection speed of the handle to avoid the handle ejecting too quickly and causing a dangerous problem.

Figure 1 The cabinet 70 is shown as a cabinet 70 in which one chassis 60 is installed, but the present invention is not limited thereto. In some embodiments, a plurality of chassis 60 may be installed in the cabinet 70. In the following embodiments, the terms "connection" may be physical connection, or may refer to direct or indirect connection between physical components, unless otherwise specified as electrical connection.

[0081] See also Figure 1 , Figure 2 and Figure 3 The electronic device 1 includes a cabinet 70 and a chassis 60, and the chassis 60 is accommodated in the cabinet 70.

In some embodiments, the electronic device 1 can be, but is not limited to, a rack-mounted server, a liquid-cooled server, a water-cooled server, or a non-liquid-cooled server (such as an air-cooled server), etc. In some embodiments, the chassis 60 includes an expansion module (not shown in the drawings), and the tray 10 is suitable for installing the expansion module, and the expansion module can be, but is not limited to, a computer hard disk, a display card, or an expansion card.

[0082] When the operator wants to take the chassis 60 out of the cabinet 70, the operator can apply force to the grip portion 33 of the handle 30 and rotate it in a direction away from the cabinet 70. The spring piece 50 on the handle 30 is locked in the first buckle hole 41 or the second buckle hole 42. The spring piece 50 can reduce the ejection speed of the handle 30 to prevent the handle 30 from ejecting too quickly and injuring the operator.

[0083] See also Figure 3 In some embodiments, the handle 30 includes a through slot 31 and a grip portion 33. The grip portion 33 is located at one end of the handle 30 and exposed to the chassis 11. The first protrusion 51 is located in the through slot 31 and protrudes toward the mounting plate 40 (see FIG. Figure 4 ). See Fig.10 , Fig.10 Show Fig. 9 In the enlarged view of the position of the area marked with B, in some embodiments, the first protrusion 51 is suitable for contacting the surface 43 of the mounting plate 40 facing the handle 30.

[0084] See also Figure 2 In some embodiments, the cabinet 70 includes a frame 71, the frame 71 includes a guide rail portion 74, the chassis 60 is slidably mounted on the guide rail portion 74 through the chassis 11 to be mounted on the frame 71, and the chassis 11 has an installation position P1 and a release position P2 relative to the frame 71. When the chassis 11 is located at the installation position P1, the gripping portion 33 of the handle 30 is connected to the clamping portion 13 of the chassis 11, the handle 30 is located at the buckle position L1, and the chassis 60 is firmly mounted in the cabinet 70; when the chassis 11 is located at the release position P2, the gripping portion 33 of the handle 30 is away from the clamping portion 13 of the chassis 11, the handle 30 is located at the unlocking position L3, and a portion of the chassis 60 is exposed outside the cabinet 70. In some embodiments, the guide rail portion 74 may include a slide rail and a pulley, the slide rail is disposed on the frame 71, and the number of the pulleys is multiple and evenly disposed on the two side walls 112 of the chassis 11. In some embodiments, the chassis 11 slides relative to the frame 71 via the guide rail portion 74, that is, the chassis 11 can slide along the guide rail portion 74. Figure 2 The tray 10 moves along the Z axis, wherein the direction of movement of the tray 10 toward the outside of the rack 71 is the exit direction D1, that is, the direction from the installation position P1 to the release position P2; the direction of movement of the tray 10 toward the inside of the rack 71 is the insertion direction D2, that is, the direction from the release position P2 to the installation position P1. In this way, the tray 10 can slide stably along the guide rail 74, and is easy to install.

[0085] See also Figure 2In some embodiments, the tray 10 further includes a connector 17, and the cabinet 70 (or rack 71) further includes a docking member 77. The connector 17 is suitable for connecting with the docking member 77 to place the chassis 60 in the cabinet 70. In some embodiments, when the chassis 11 is located at the installation position P1, the connector 17 is connected to the docking member 77; when the chassis 11 is located at the release position P2, the connector 17 withdraws from the connection relationship with the docking member 77. In some embodiments, the connector 17 can be a blind plug connector, a water cooling connector, or a connector suitable for a liquid-cooled server, and the docking member 77 is a corresponding connection connector. In some embodiments, the chassis 11 includes a carrying portion 15 and a clamping portion 13. The clamping portion 13 and the connector 17 are respectively arranged at two opposite ends of the carrying portion 15, and the carrying portion 15 is suitable for carrying expansion modules. In some embodiments, springs are provided inside the connecting member 17 and the docking member 77. When the connecting member 17 and the docking member 77 are connected, the springs generate a rebound force due to deformation. This rebound force is suitable for pushing the tray 10 away from the docking member 77 (i.e., the exit direction D1).

[0086] See also Figure 3 In some embodiments, the handle 30 can be directly or indirectly pivoted to the chassis 11 by a pivot member, for example, the handle 30 is directly pivoted to the chassis 11 by riveting the pivot member to the chassis 11, or the handle 30 is indirectly pivoted to the chassis 11 by a pivot member 20 (e.g. Figure 3 In some embodiments, the number of handles 30 is not limited, and can be one or more. In some embodiments, two handles 30 are used as an example. Figure 3 As shown, the short shaft 23 (pivot member) of each handle 30 is located on both sides of the chassis 11, so that the operator can evenly apply force to the chassis 60 through each handle 30, and stably install the chassis 60 on the frame 71, or withdraw the chassis 60 from the frame 71 (such as Figure 2 shown).

[0087] See also Figure 3 In some embodiments, the grip portion 33 includes a grip hole 330 and a pressing member 332. The pressing member 332 is provided with a hook, and the clamping portion 13 is provided with a slot, and the hook corresponds to the slot. When disassembling, the operator grips the handle 30 through the grip hole 330 and presses the pressing member 332 to release the connection between the pressing member 332 and the clamping portion 13. Figure 2 The springs in the connecting member 17 and the docking member 77 push the tray 10 away from the frame 71 with a rebound force (ie, the tray 10 moves along the exit direction D1 ), and the handle 30 correspondingly rotates around the short axis 23 , so that the gripping portion 33 is away from the clamping portion 13 .

[0088] Specifically, see Figure 3In some embodiments, the handle 30 includes a latch portion 34, and the latch portion 34 and the grip portion 33 are respectively located at two ends of the handle 30, wherein the distance between one end of the handle 30 and the short axis 23 is greater than the distance between the other end and the short axis 23, which means that the distance between the grip portion 33 and the short axis 23 is greater than the distance between the latch portion 34 and the short axis 23. In some embodiments, the latch portion 34 includes a first hook portion 35 and a second hook portion 36, and the first hook portion 35 is connected to the second hook portion 36 to form a notch portion 37, and the two ends of the notch portion 37 are respectively connected to the first hook portion 35 and the second hook portion 36. In some embodiments, the handle 30 is suitable for cooperating with the positioning portion 72 of the cabinet 70 through the latch portion 34 to position the chassis 60 in the cabinet 70. In some embodiments, the notch portion 37 corresponds to the positioning portion 72, so that the chassis 60 is positioned in the cabinet 70. Figure 3 For example, the notch 37 is trapezoidal and is generally wide outside and narrow inside. The opening direction of the notch 37 is toward the positioning portion 72. The positioning portion 72 is a protrusion. The length of the positioning portion 72 is substantially less than or equal to the opening size of the notch 37.

[0089] See also Figure 3 and Fig.11 , Fig.11 A partial schematic diagram of a rack 71 according to some embodiments is shown, showing the handle 30 in the unlocking position L3, the mounting plate 40 is indicated by a dotted line, and the insertion direction D2 of the tray 10 is indicated by an arrow. In some embodiments, during the rotation process of the handle 30, the positioning portion 72 is in substantial contact with the first hook portion 35 and the second hook portion 36 respectively. In some embodiments, during the rotation process of the handle 30, the positioning portion 72 is in substantial contact with the first hook portion 35 and the second hook portion 36 respectively. Figure 3 When the chassis 11 is located at the installation position P1, the first hook portion 35 substantially contacts the positioning portion 72, and the first hook portion 35 and the positioning portion 72 interfere with each other. Figure 2 and Figure 3 In some embodiments, the resilient force provided by the connecting member 17 and the docking member 77 pushes the notch portion 37 of the latch portion 34 toward the positioning portion 72. Fig.11 In some embodiments, Fig.11 When the chassis 11 is located at the unlocking position L3 , the second hook portion 36 substantially contacts the positioning portion 72 .

Figure 4In some embodiments, the pivoting member 20 includes an intermediate member 21 and a short shaft 23. The intermediate member 21 is fixed to the chassis 11. The short shaft 23 is passed through the intermediate member 21. The handle 30 is pivoted to the chassis 11 through the short shaft 23. In some embodiments, the intermediate member 21 is provided with a central hole 212 and a through hole 210. The number of the through hole 210 is not limited and can be multiple or one. The through hole 210 is provided at a position surrounding the outer periphery of the central hole 212. Please refer to Figure 4 In some embodiments, the intermediate member 21 is provided with a central hole 212 and four through-holes 210, and the handle 30 is provided with a mounting hole 32, which can be movably aligned with one of the plurality of through-holes 210. For example, during installation, the short shaft 23 can first pass through the central hole 212 of the intermediate member 21 and be riveted to the intermediate member 21, and then the short shaft 23 is passed through the shaft hole 38 of the handle 30, and the intermediate member 21 is located between the short shaft 23 and the handle 30. Then, the intermediate member 21 is welded to the chassis 11 by aligning the mounting holes 32 on the handle 30 with different through-holes 210. In this way, the tray 10 can be applied to a liquid-cooled server, and the problem of liquid leakage in the chassis 60 caused by opening holes in the chassis 11 to install the pivoting member can be avoided.

[0091] See also Figure 3 In some embodiments, the first buckle hole 41 of the mounting plate 40 includes a support wall 411 and a bottom wall 413 disposed on opposite sides of the first buckle hole 41, the bottom wall 413 is substantially perpendicular to the guide rail portion 74, the support wall 411 and the bottom wall 413 are formed at an oblique angle α, and the width w1 of the first buckle hole 41 is the distance between the support wall 411 and the bottom wall 413.

In some embodiments, when the first protrusion 51 is located in the second buckle hole 42, the first protrusion 51 substantially contacts the mounting plate 40 (or substantially contacts the mounting plate 40). Figure 3 The long sides 421, 423 in the figure).

[0096] On the other hand, see Figure 4 , Figure 6 and Fig.10 In some embodiments, the extension portion 53 extends outward from one end of the first protrusion 51, wherein the outward direction is any direction outward relative to the main body of the first protrusion 51. Fig.13A In some embodiments, the first protrusion 51 is located between the extension 53 and the second protrusion 55. Fig. 13B In some embodiments, the extension portion 53 is located between the first protrusion 51 and the second protrusion 55. Figure 6 In some embodiments, there is an angle β between the first protrusion 51 and the body 57. When the first protrusion 51 is located in the first buckle hole 41 or the second buckle hole 42, the angle β is about 45 degrees. When the first protrusion 51 abuts against the surface 43 of the mounting plate 40, the angle β becomes smaller due to deformation. Figure 6 In some embodiments, the height of the first protrusion 51 is substantially greater than or equal to the distance H between the chassis 11 and the handle 30. In some embodiments, the height difference generated by the corresponding deformation of the height of the first protrusion 51 is substantially less than or equal to the distance H. Fig.10 In some embodiments, when the first protrusion 51 abuts against the surface 43 of the mounting plate 40 and deforms, the extension 53 is correspondingly pushed toward the chassis 11 and contacts the chassis 11. In some embodiments, Fig.10 The angle β′ of the first protrusion 51 is less than 45 degrees, and the height of the first protrusion 51 is substantially equal to the thickness of the handle 30 (or the depth of the through groove 31). In some embodiments, the first protrusion 51 is located in the space S sandwiched between the surface 43 of the mounting plate 40 and the chassis 11, and the first protrusion 51 contacts the surface 43 of the mounting plate 40. In this way, when the handle 30 rotates toward the outside of the cabinet 70, the extension 53 and the chassis 11 generate friction to slowly retract the handle 30.

[0097] See also Figure 4 In some embodiments, the second protrusion 55 and the extension 53 are respectively located at two ends of the first protrusion 51, which means that along Figure 4With respect to the Z axis, the extension portion 53 is located at one end of the first convex portion 51 facing the −Z axis, and the second convex portion 55 is located at one end of the first convex portion 51 facing the +Z axis.

[0098] See also Figure 7 , Figure 8 , Fig. 9 and Fig.10 , Figure 7 A partial schematic diagram of a frame 71 according to some embodiments is shown, showing the handle 30 in the stop position L2, and the mounting plate 40 is represented by a dotted line; Figure 8 A partial schematic diagram of a rack 71 according to some embodiments is shown, showing that the spring 50 abuts against the surface 43 of the mounting plate 40, and the mounting plate 40 is represented by a dotted line; Fig. 9 Show Figure 8 The partial cross-sectional view at the position marked 9-9 shows that the first protrusion 51 abuts against the mounting plate 40, and the extension 53 abuts against the bottom plate 11; Fig. 9 Show Figure 8 The partial cross-sectional view at position 9 - 9 shows that the first protrusion 51 abuts against the surface 43 of the mounting plate 40 , and the extension 53 abuts against the chassis 11 .

[0099] See also Figure 3 and Fig.11 In some embodiments, Figure 3 In the embodiment, when the handle 30 is located at the buckling position L1, the first protrusion 51 is located at the first buckling hole 41, and the gripping portion 33 is engaged with the engaging portion 13; Fig.11 When the handle 30 is at the unfastening position L3, the first protrusion 51 is locked in the second buckle hole 42, the gripping portion 33 is away from the clamping portion 13, and the second hook portion 36 contacts the positioning portion 72. In some embodiments, please refer to Figure 3 When the chassis 11 slides toward the outside of the cabinet 70 along the exit direction D1, the two handles 30 rotate with their short axes 23 as the rotation axes and in the direction away from the clamping portion 13, and the handles 30 rotate from the buckling position L1 to Fig.11 In some embodiments, see Fig.11 When the chassis 11 slides toward the inside of the cabinet 70 along the insertion direction D2, the handle 30 rotates toward the clamping portion 13 with the short axis 23 as the rotation axis (i.e. Fig.11 The handle 30 is rotated from the unlocking position L3 to Figure 3 Thus, during installation, the positioning portion 72 can prevent the operator from applying excessive force to move the tray 10 toward the interior of the cabinet 70 ( Fig.11 In addition, the latch portion 34 and the positioning portion 72 can limit the rotation range of the handle 30 on the XZ plane, and provide a stable force application point for the operator through the structural configuration of the buckle position L1 and the unlocking position L3.

[0100] See also Figure 7 In some embodiments, when the handle 30 is located between the buckle position L1 and the unlock position L3, the first protrusion 51 is adapted to continuously contact the mounting plate 40. Specifically, in some embodiments, when the handle 30 is located between the buckle position L1 and the unlock position L3, the first protrusion 51 is adapted to continuously contact the mounting plate 40. Figure 3 The fastening position L1 is facing Fig.11 During the rotation from the unfastening position L3, the first protrusion 51 contacts the abutting wall 411 of the first buckle hole 41, and the handle 30 is located at the stop position L2. In some embodiments, when the handle 30 is located at the stop position L2, the first hook 35 substantially contacts the positioning portion 72, which means that when disassembling, Figure 2 The repulsive force provided by the connecting member 17 and the docking member 77 causes the notch portion 37 to be pushed toward the positioning portion 72. Since the abutting wall 73 of the positioning portion 72 abuts against the first hook portion 35, the first hook portion 35 interferes with the positioning portion 72, and the handle 30 rotates correspondingly with the short axis 23 as the rotation axis, so that the grip portion 33 is pushed away from the clamping portion 13. In addition, in this embodiment, when the handle 30 is located at the stop position L2, the first protrusion 51 contacts the abutting wall 411 of the first buckle hole 41, so that the first buckle hole 41 can slow down the speed at which the handle 30 rotates toward the unlocking position L3.

[0101] Since the handle 30 has a brake position L2, it can provide resistance to slow down the speed at which the handle 30 rotates toward the unlocking position L3. In this way, through a two-stage unlocking method, the handle 30 moves from the engaging position L1 to the brake position L2 to the unlocking position L3, thereby slowly retracting the handle 30 to reduce the risk of injury to the operator.

[0102] In addition, in some embodiments, when the operator pulls the handle 30 to rotate toward the unlocking position L3, see Figure 8 During the rotation, the first protrusion 51 is separated from the first buckle hole 41, and the handle 30 is located Figure 3 The buckle position L1 and Fig.11 between the unfastening positions L3, see Fig.10 , the first protrusion 51 contacts the surface 43 of the mounting plate 40, which means that during the rotation of the handle 30, the through slot 31 will be located in the space S sandwiched between the surface 43 of the mounting plate 40 and the chassis 11, that is, the through slot 31 is located at a position that does not correspond to the first buckle hole 41 and the second buckle hole 42, and the first protrusion 51 can be pushed toward the chassis 11 and located in the space S. The first protrusion 51 abuts against the surface 43 of the mounting plate 40 to provide friction, further slowing down the speed at which the handle 30 rotates toward the unfastened position L3. In some embodiments, when the through slot 31 is located in the space S, the first protrusion 51 is in substantial contact with the chassis 11 and the mounting plate 40, respectively.

[0103] In addition, in some embodiments, see Figure 2The guide stroke of the connecting member 17 and the docking member 77 is about 26 mm. For example, the tray 10 slides from the installation position P1 to the release position P2 along the withdrawal direction D1 under the rebound force. During the sliding process, please refer to Figure 7 , Figure 8 , Fig.10 and Fig.11 ,At Figure 7 , the first protrusion 51 contacts the abutting wall 411 of the first buckle hole 41, the handle 30 is located at the stop position L2, and the sliding distance of the tray 10 is 5 mm; please refer to Figure 8 and Fig.10 As the handle 30 continues to rotate, the first protrusion 51 is pushed into Fig.10 The space S shown in FIG. 4 and contacting the surface 43 of the mounting plate 40, Figure 8 The tray 10 shown has a sliding distance of 13 mm; finally, Fig.11 , the first protrusion 51 is located at the second buckle hole 42, the handle 30 is located at the unfastening position L3, and the sliding distance of the tray 10 is 26 mm, which means that Figure 2 The distance between the installation position P1 and the release position P2 of the middle tray 10 is 26 mm.

[0104] In addition, please refer to Figure 2 , Figure 3 , Figure 7 , Figure 8 , Fig.10 and Fig.11 ,At Figure 2 In the installed state, the tray 10 is located at the installation position P1, and the handle 30 is located at the buckling position L1. Figure 3 , the first protrusion 51 is located at the first buckle hole 41. When the operator wants to remove the chassis 60 from the cabinet 70, the operator first presses the pressing member 332 to separate the pressing member 332 from the clamping portion 13, and then the inner spring of the connecting member 17 and the docking member 77 pushes the tray 10 through the guide rail portion 74 along the exit direction D1 toward the outside of the cabinet 70 with the rebound force. Here, the notch portion 37 of the handle 30 is pushed toward the positioning portion 72, and the first hook portion 35 correspondingly presses against the positioning portion 72 to rotate the handle 30 around the short axis 23 away from the clamping portion 13, and the first hook portion 35 interferes with the positioning portion 72. Next, please refer to Figure 7 Since the spring sheet 50 is fixed to the handle 30, when the handle 30 rotates, the first protrusion 51 of the spring sheet 50 rotates synchronously toward the abutting wall 411 of the first buckle hole 41. The handle 30 is located at the stop position L2. The first protrusion 51 contacts the abutting wall 411 of the first buckle hole 41 and provides a resistance to the handle 30 to slow down the speed of the handle 30 rotating away from the clamping portion 13. Figure 8 and Fig.10 , the handle 30 continues to rotate and leaves Figure 7At the stop position L2, the through slot 31 is located at a position not corresponding to the first buckle hole 41 and the second buckle hole 42. Fig.10 At this time, the spring 50 is deformed accordingly, which means that Fig.10 The angle β′ is less than Figure 6 The first protrusion 51 is pushed into the space S and abuts against the surface 43 of the mounting plate 40, and the extension 53 substantially contacts the chassis 11. In this way, the first protrusion 51 and the extension 53 further provide friction to slowly retreat the handle 30. Finally, please refer to Fig.11 , the handle 30 is rotated to the unlocking position L3, the first protrusion 51 is located in the second buckle hole 42, the second hook 36 abuts the positioning portion 72, and the first hook 35 leaves the positioning portion 72. In this way, the first hook 35 does not interfere with the positioning portion 72, and the operator can pull the handle 30 and drive the chassis 60 to leave the cabinet 70. Here, the tray 10 is located as shown in FIG. Figure 2 The release position P2 is shown.

[0105] On the other hand, when the operator wants to install the chassis 60 in the cabinet 70, first, refer to Figure 2 , the operator first inserts the chassis 60 into the rack 71 to push the tray 10 on the guide rail 74 toward the inside of the rack 71 (along the insertion direction D2). At this time, the tray 10 is located at the release position P2, the connecting member 17 and the docking member 77 have not yet docked, the handle 30 is located at the unlocking position L3, and the first protrusion 51 is located at the second buckle hole 42 (such as Fig.11 Next, see Fig.11 The operator holds the handle 30 through the grip hole 330 and pushes the handle 30 toward the clamping portion 13 (i.e., the handle 30 moves along the Fig.11 The tray 10 is pushed away accordingly. Figure 2 The release position P2 is moved toward the inside of the frame 71. Figure 7 The handle 30 continues to rotate, and the second hook portion 35 abuts against the positioning portion 72, so that the operator can use the positioning portion 72 as a fulcrum to effortlessly push the tray 10 to the position as shown in FIG. Figure 2 Mounting position P1 shown. See also Figure 3 , the first protrusion 51 rotates to the first buckle hole 41, the operator hooks the gripping portion 33 on the clamping portion 13, and the handle 30 is located at the buckling position L1. Figure 2 , the connecting member 17 is docked with the docking member 77 , and the operator can finally lock the holding portion 33 to the clamping portion 13 through a locking element. Here, the tray 10 is located at the installation position P1 .

[0106] In summary, according to some embodiments, by providing a spring sheet on the handle, the spring sheet selectively engages with the first buckle hole or the second buckle hole of the mounting plate, and the spring sheet can reduce the ejection speed of the handle to avoid the handle ejecting too quickly and causing a dangerous problem. In addition, the handle can facilitate the operator to apply force, and is convenient for installation.
