Description

Technical Field

[0001] This application relates to the field of hard drive assembly and disassembly technology, specifically to a hard drive tray, chassis, and electronic equipment. Background Technology

[0002] Hard drives are indispensable and important storage devices in electronic devices such as data center servers, storage servers, and computers.

[0003] Taking servers as an example, in current technology, hard drives are generally installed and fixed in the server chassis using brackets. Specifically, the brackets are mostly box-shaped and are secured to the inner wall of the chassis with screws. The hard drives are installed in the brackets and are also assembled and fixed to the brackets with screws.

[0004] This method requires screws to be screwed in or removed with a screwdriver when disassembling or assembling the hard drive, which is cumbersome and time-consuming, making hard drive disassembly and maintenance very inconvenient. Utility Model Content

[0005] In view of the above problems, embodiments of this application provide a hard drive bracket, chassis, and electronic equipment, which can simplify the hard drive disassembly and assembly operations and improve the efficiency of hard drive disassembly, assembly, and maintenance.

[0006] According to one aspect of the embodiments of this application, a hard disk tray is provided, including: a base, limiting members, gears, and a driving member; the base has a receiving groove for inserting a hard disk; the limiting members include multiple members, which are slidably disposed through opposite side walls of the receiving groove; a first rack is disposed on the limiting members at a position outside the receiving groove; the gears include multiple members, which are rotatably disposed on the base and located on opposite sides of the receiving groove, and the multiple gears mesh with the multiple first racks one-to-one; the driving member includes at least two sliding rods and a bridge. A connecting rod is connected between at least two sliding rods, which are slidably disposed on the base and located on opposite sides of the receiving groove. A second rack is provided on the sliding rod, and the second rack meshes with a gear. At least one of the driving member, gear, and limiting member is connected to the base by an elastic member, which provides a spring force to make the limiting member slide out toward the receiving groove and engage with the hard disk. The connecting rod is used to drive the at least two sliding rods to slide synchronously, so that the limiting member slides away from the receiving groove and separates from the hard disk through the meshing transmission of the second rack, gear, and first rack.

[0007] In one alternative embodiment, the limiting member has a force-receiving end that extends into the receiving groove and is used to engage with the hard drive. The force-receiving end has a guide slope on the side facing the opening of the receiving groove. The guide slope is used to cause the limiting member to slide and retract away from the receiving groove when the hard drive is inserted, due to the pressure of the hard drive.

[0008] In one alternative embodiment, the base has an opening on one side of the receiving groove, the side of which is adjacent to the side of the limiting member; the bottom of the receiving groove is provided with a limiting post, which is used to be inserted into the limiting hole at the bottom of the hard drive.

[0009] In one alternative embodiment, the elastic element includes a first compression elastic element connected between the limiting element and the base; and / or, the elastic element includes a second compression elastic element connected between the driving element and the base; and / or, the elastic element includes a torsional elastic element connected between the gear and the base.

[0010] In one alternative embodiment, the base includes a bottom plate, side plates, and a cover plate. The bottom plate is the bottom of the receiving groove. The side plates are fixed to the bottom plate and include multiple side plates. The multiple side plates surround each other to form the receiving groove and surround each other on the outer periphery of the receiving groove to form an installation cavity. The cover plate is detachably installed on the opening of the installation cavity on the side opposite to the bottom plate. The limiting member, gear, driving member, and elastic member are all disposed in the installation cavity.

[0011] In one alternative configuration, a button is provided on the side of the connecting rod opposite to the receiving groove, and a clearance opening is provided on the side plate for the button to protrude outward.

[0012] In one alternative embodiment, the mounting cavity is provided with at least two guide grooves, which are located on opposite sides of the receiving groove, and at least two slide rods are slidably disposed in the at least two guide grooves.

[0013] In one alternative embodiment, the inner wall of the cover plate is provided with at least two abutting blocks, which are located on opposite sides of the receiving groove, and the at least two abutting blocks abut against at least two sliding rods to confine the sliding rods within the guide groove.

[0014] According to another aspect of the embodiments of this application, a chassis is provided, including a chassis body and a hard drive tray as described above, wherein the hard drive tray is disposed within the chassis body.

[0015] According to another aspect of the embodiments of this application, an electronic device is provided, including a hard disk and the aforementioned chassis, wherein the hard disk is disposed on a hard disk tray within the chassis.

[0016] In the hard drive bracket provided in this application embodiment, after a receiving slot for installing a hard drive is provided on the base, a limiting member is slidably provided through the two side walls opposite to the receiving slot. By extending or retracting the limiting member in the receiving slot, the hard drive in the receiving slot can be fixed and released.

[0017] Based on this, in order to ensure that the hard drive can be reliably installed and fixed on the hard drive bracket, an elastic element is provided that can extend toward the receiving slot to the limiting element, preventing the limiting element from retracting due to tilting, shaking, or other situations, thereby preventing the hard drive from falling off.

[0018] In addition, to facilitate the removal of the hard drive, a drive component and a gear are also provided on the base. The limiting component and the drive component are driven by the meshing of the gear with the rack (first rack and second rack). Applying force to the drive component can simultaneously drive the limiting components on both sides to retract away from the receiving groove, so that the hard drive can be easily and conveniently removed from the receiving groove.

[0019] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0050] Currently, the method of fixing hard drives with screws not only makes hard drive installation and removal time-consuming and laborious, but the screws used to secure the hard drive are also small and are easy to fall out or be lost during the installation and removal process. Once a screw falls into the gap inside the computer case, it takes time to find it, which further affects the efficiency of hard drive installation and removal maintenance.

[0051] To address the problems of inconvenient and inefficient hard drive installation and removal, this application proposes a hard drive bracket that allows for quick and convenient hard drive installation and removal. Please refer to the following for details. Figure 1 and Figure 2 The figures show the three-dimensional and exploded views of the hard drive tray. As shown, the hard drive tray 100 includes a base 110, a limiting member 120, a gear 130, and a driving member 140. The base 110 is the main structure of the hard drive tray 100, responsible for supporting the hard drive and assembling other components. The base 110 has a receiving slot 111 for inserting the hard drive. The receiving slot 111 can be a three-sided enclosed slot as shown in the figure, or it can be a four-sided enclosed slot.

[0052] The limiting member 120 is mainly responsible for engaging with the installed hard drive to limit its movement, which will be described in detail below. Multiple limiting members 120 are included, and each limiting member 120 is slidably disposed through the opposite side walls of the receiving groove 111. Specifically, windows 112 are provided on the opposite side walls of the receiving groove 111 for the limiting members 120 to slide and extend. The windows 112 guide and limit the limiting members 120, ensuring that the limiting members 120 slide along the direction through both ends of the windows 112 (as indicated by the double arrow X in the figure). Of course, in some other embodiments, in order to ensure the accuracy of the sliding direction of the limiting member 120 and the stability of the structure, a sliding guide structure, such as a guide rail or a slide groove, can be provided on the side of the window 112 away from the receiving groove 111. By sliding the limiting member 120 with the sliding guide structure, the accuracy of the sliding direction of the limiting member 120 can be ensured. At the same time, the sliding guide structure can also play a supporting role for the limiting member 120 to ensure that the limiting member 120 will not tilt up and down at both ends, and to ensure that the limiting member 120 is structurally stable and slides easily and flexibly.

[0053] In addition, please refer to further information. Figure 3 The three-dimensional structure of the limiting member 120 shown can also have a step portion 1201 provided on the limiting member 120. The step portion 1201 is used to abut against the outer surface of the side wall of the receiving groove 111 to limit the extension distance of the limiting member 120 and prevent the limiting member 120 from over-extending and falling into the receiving groove 111.

[0054] Please combine Figure 2 and Figure 3 A first rack 121 is provided on the limiting member 120 at a position outside the receiving groove 111. There are also multiple gears 130, which are rotatably disposed on the base 110 and are respectively located on opposite sides of the receiving groove 111. The multiple gears 130 mesh with the multiple first racks 121 in a one-to-one correspondence. This means that when the gear 130 rotates, the limiting member 120 where the corresponding first rack 121 is located will slide accordingly.

[0055] The driving component 140 drives the gear 130 to rotate, thereby causing the limiting component 120 to slide and release the locking of the hard drive. This part will also be described in detail in the following document. The driving component 140 includes at least two slide rods 141 and a connecting rod 142 bridging the at least two slide rods 141. The at least two slide rods 141 are slidably disposed on the base 110 and are located on opposite sides of the receiving groove 111. The sliding direction of the slide rods 141 is as shown by the double arrow Y in the figure. The at least two slide rods 141 and the connecting rod 142 can be Figure 2 The integrated structure shown can also be assembled and fixed together by screws or other means. Specifically, the slide rod 141 can form a sliding fit with the base 110 through structures such as guide rails, pulleys, and slide grooves.

[0056] Please combine further Figure 4 The three-dimensional structure of the driving member 140 shown has a second rack 1411 on the slide rod 141. The second rack 1411 meshes with the gear 130, so that when the slide rod 141 slides, the gear 130 will rotate under the drive of the second rack 1411 and drive the limiting member 120 to slide.

[0057] It should be noted that, due to the sliding direction of slider 141 ( Figure 2 The direction indicated by the double arrow Y) and the sliding direction of the limiting member 120 ( Figure 2 The directions indicated by the double arrows X are perpendicular to each other. Therefore, for the transmission to function properly, the axial direction of gear 130 (…) Figure 2 The dimensions (in the direction indicated by the double arrow Z) are set to be relatively large, and the second rack 1411 and the first rack 121 are respectively meshed at different positions along the axial direction of the gear 130, so that the slide rod 141 and the limiting member 120 avoid each other when sliding.

[0058] At least one of the drive member 140, gear 130, and limiting member 120 is connected to the base 110 by an elastic member. The elastic member provides a spring force to allow the limiting member 120 to slide out toward the receiving groove 111 and engage with the hard disk. This arrangement allows the limiting member 120 to automatically pop out and remain in place when no other external force is applied. The specific implementation of the elastic member will be described in detail below.

[0059] like Figure 2 and Figure 3 As shown, in some embodiments, the limiting member 120 may have a force-receiving end 122 extending into the receiving groove 111 for engaging with the hard drive, and a guide slope 123 may be provided on the side of the force-receiving end 122 facing the opening of the receiving groove 111. Figure 5 Based on the state shown, the hard disk 200 is inserted downwards into the receiving slot 111. When the bottom of the hard disk 200 abuts against the guide ramp 123, the guide ramp 123 will be squeezed by the hard disk 200, causing the limiting member 120 to slide and retract in the direction away from the receiving slot 111, forming a... Figure 6 The state shown is in Figure 6 In the image, to better illustrate the shrinkage of the limiting component 120 due to pressure from the hard drive 200, the hard drive 200 is rendered with dotted lines for perspective. For example... Figure 7 As shown, when the hard disk 200 is installed in place, the limiting member 120 automatically pops out under the elastic force of the elastic member and engages with the hard disk to fix the hard disk 200 in the receiving slot 111.

[0060] Specifically, such as Figure 7As shown in the assembly structure of the hard disk 200 and the hard disk bracket 100, after the hard disk 200 is installed in the receiving slot 111, the limiting member 120 can slide out and engage with the top of the hard disk 200 to restrict the hard disk 200 from moving upward. Of course, in some other embodiments, the limiting member 120 can also be set lower, and after it extends out, it will be inserted into the connection holes 210 on both sides of the hard disk 200 (e.g., Figure 5 As shown in the figure, the hard disk 200 is fixed in place.

[0061] Alternatively, the guide ramp 123 may not be provided on the limiting member 120. When a hard drive needs to be installed, force is applied to the connecting rod 142 to drive at least two sliding rods 141 along... Figure 2 When the double arrow Y slides to the upper right, the gear 130 rotates accordingly and drives the limiting member 120 to slide and retract in the direction indicated by the double arrow X toward the side away from the receiving groove 111.

[0062] When the limiting component 120 is as follows Figure 8 After the drive is fully retracted into the side wall of the receiving slot 111, the installation space inside the receiving slot 111 is fully opened, allowing the hard drive to be smoothly installed into the receiving slot 111. After the hard drive is installed, the force applied to the connecting rod 142 is released, and the limiting member 120 will automatically extend under the elastic force of the elastic member and limit and fix the hard drive.

[0063] When removing hard drive 200, then... Figure 7 Based on the above, by applying force to the connecting rod 142, the limiting member 120 slides and retracts in the direction away from the receiving groove 111 and separates from the hard disk 200, and then the hard disk 200 can be removed from the receiving groove 111.

[0064] exist Figure 1 and Figure 2 In the specific embodiment shown, there are four limiting members 120, with two on each side of the receiving slot 111. This allows for more reliable positioning of the hard disk 200 using the limiting members 120. Correspondingly, there are also four gears 130, with two second racks 1411 on each side of the slide bar 141. When the slide bars 141 on both sides slide, they simultaneously drive all the gears 130 to rotate, causing all the limiting members 120 to retract inwards. This configuration eliminates the need for individual driving of each limiting member 120, simplifying the driving operation and ensuring ease of operation when removing the hard disk 200.

[0065] Regarding the specific structure of the aforementioned elastic element, this application proposes several implementation schemes. Please refer to them for details. Figure 2 and Figure 3 The elastic element includes a first compression elastic element 151, which is connected between the limiting member 120 and the base 110 and provides elastic force to the limiting member 120 to slide toward the receiving groove 111.

[0066] The first compression elastic element 151 can be a compression spring. To ensure the accuracy of the direction of the elastic force provided by the first compression elastic element 151, such as... Figure 3 and Figure 9 As shown, a positioning hole 124 can be provided at one end of the limiting member 120 away from the receiving groove 111, and a first positioning post 113 can be provided on the base 110 at a position opposite to the positioning hole 124. One end of the first compression elastic member 151 extends into the positioning hole 124, and the other end is sleeved and fixed on the first positioning post 113, so that the first compression elastic member 151 is restricted to a state of deformation along the sliding direction of the limiting member 120.

[0067] Of course, in some other embodiments, the positions of the positioning hole 124 and the first positioning post 113 can also be interchanged, that is, the first positioning post 113 is provided on the limiting member 120, and the positioning hole 124 is provided on the base 110. Alternatively, the first positioning post 113 or the positioning hole 124 can be provided on both the limiting member 120 and the base 110. The first compression elastic member 151 can also be a spring sheet, an elastic soft rubber block, etc. Correspondingly, limiting grooves can be provided on the limiting member 120 and the base 110 to limit the two ends of the first compression elastic member 151.

[0068] Please see Figure 2 , Figure 4 and Figure 10 The elastic element may include a second compression elastic element 152, which is connected between the drive member 140 and the base 110. Specifically, the second compression elastic element 152 can also be a compression spring, with one end sleeved on the second positioning post 1421 on the connecting rod 142 and the other end abutting against the base 110, providing a spring force to the connecting rod 142 to slide away from the receiving groove 111, so that the connecting rod 142 can drive the limiting member 120 to slide towards the receiving groove 111 via the slide rod 141. The second compression elastic element 152 can also be assembled and connected to the drive member 140 and the base 110 in other ways, such as being inserted into a hole for positioning, etc. Of course, the second compression elastic element 152 can also be a spring sheet, elastic soft rubber block, etc. In addition, the second compression elastic element 152 can also be connected between the slide rod 141 and the base 110, and the direction of the provided spring force remains unchanged.

[0069] The elastic element may also include a torsion elastic element (not shown), which may be a torsion spring, a clockwork, etc. It is connected between the gear 130 and the base 110 to provide torque to the gear 130 so that the gear has a tendency to rotate and drive the limiting element 120 to slide out toward the receiving groove 111 without other external forces.

[0070] The elastic element may include any or all of the first compression elastic element 151, the second compression elastic element 152, and the torsional elastic element.

[0071] Please refer to it again. Figure 9 In some embodiments, the base 110 has an opening 114 on one side of the receiving groove 111, and the side with the opening 114 is adjacent to the side with the limiting member 120. The opening 114 can, on the one hand, avoid space on the interface of the hard drive 200, so as to ensure that the wire connector on the motherboard can be easily plugged and unplugged into the interface on the hard drive 200. On the other hand, when removing the hard drive, after the limiting member 120 is unlocked and retracted, the operator can easily pull up the hard drive 200 by hand at the opening 114, so as to make the removal of the hard drive 200 easy and convenient.

[0072] The limiting component 120 adopts, as follows Figure 7 As shown, the clip is positioned at the top of the hard drive 200 to limit its movement. The opening 114 allows the hard drive 200 to easily slide out from the opening 114. Therefore, as... Figure 9 As shown, a limiting post 115 can be provided at the bottom of the receiving slot 111. The limiting post 115 is used to insert into the limiting hole 220 at the bottom of the hard disk 200 (e.g., Figure 11 As shown in the three-dimensional structure from the bottom view of the hard disk 200, the hard disk 200 is arranged along... Figure 1 The double arrows X and Y indicate the direction of the limit, and together with the limit member 120, the hard disk 200 is limited in the direction indicated by the double arrow Z, so that the hard disk 200 is reliably fixed in the receiving slot 111.

[0073] The bottom of the hard disk 200 typically has four limiting holes 220. Correspondingly, the bottom of the receiving slot 111 can be equipped with four limiting posts 115 that correspond one-to-one with the four limiting holes 220 to fully ensure the stability of the hard disk 200 after assembly.

[0074] To ensure the reliability of each component after assembly on the base 110, this application further proposes an implementation method, which can be found in the following details. Figure 9 and Figure 12 , Figure 12 The exploded structure of the base 110 is shown in the figure. As shown, the base 110 includes a base plate 116, side plates 117, and a cover plate 118. The base plate 116 forms the bottom of the receiving groove 111, that is, the bottom of the receiving groove 111 is formed by the base plate 116, and the side plates 117 are fixed to the base plate. The side plates 117 include multiple pieces, which together form the receiving groove 111 and also form a mounting cavity 119 around the outer periphery of the receiving groove 111. The cover plate 118 is detachably placed over the opening 1191 of the mounting cavity 119 on the side opposite to the base plate 116. Please refer to... Figure 2The limiting component 120, gear 130, driving component 140 and elastic component are all disposed in the mounting cavity 119.

[0075] In this embodiment, a mounting cavity 119 is formed by the side plate 117 surrounding the accommodating groove 111. The limiting member 120, gear 130, driving member 140 and elastic member are assembled in the mounting cavity 119, and the opening 1191 of the mounting cavity 119 is closed by the cover plate 118, so that each component is completely covered and protected in the mounting cavity 119, thereby effectively ensuring the stability and reliability of the movement of each component.

[0076] Specifically, the base plate 116 and the side plates 117, as well as multiple side plates 117, can be integrally formed or fixed to each other by welding, screws, or other methods. The cover plate 118 can be detachably connected to the side plates 117 by screws to seal the opening 1191. Figure 12 In the specific embodiment shown, a first connecting plate 1171 parallel to the cover plate 118 extends from the side plate 117, and the first connecting plate 1171 and the cover plate 118 are fixedly connected by screws. A second connecting plate 1181 parallel to the side plate 117 extends from the cover plate 118, and the second connecting plate 1181 and the side plate 117 are fixedly connected by screws.

[0077] In addition, for the rotating assembly of gear 130, such as Figure 12 As shown, mounting holes 1182 can be opened on the base plate 116 and the cover plate 118 respectively, and the rotating shafts 131 at both ends of the gear 130 are respectively installed into the mounting holes 1182 on the base plate 116 and the cover plate 118 to form a rotational fit.

[0078] To facilitate applying force to the connecting rod 142 to retract the limiting member 120, such as Figure 1 and Figure 2 As shown, a button 1422 is protruding on the side of the connecting rod 142 opposite to the receiving groove 111, and a clearance opening 1172 is provided on the side plate 117 for the button 1422 to protrude outward. When it is necessary to remove the hard drive 200, pressing the button 1422 inward with your hand can easily drive the limiting member 120 to retract inward to release the restriction on the hard drive 200, making the operation very convenient.

[0079] Regarding the specific sliding assembly structure of the slide rod 141 in the mounting cavity 119, this application proposes one embodiment. Please refer to the following again. Figure 9 and further combine Figure 13 , Figure 13The figure shows the assembly structure of the limiting member 120, gear 130, and drive member 140 within the mounting cavity 119. As shown, at least two guide grooves 1192 can be provided within the mounting cavity 119, with the at least two guide grooves 1192 located on opposite sides of the receiving groove 111. At least two slide rods 141 are slidably disposed within the at least two guide grooves 1192 in a one-to-one correspondence. By providing guide grooves 1192 to guide and limit the sliding of the slide rods 141, the accuracy of the sliding direction of the slide rods 141 can be ensured.

[0080] To further improve the stability of the slider 141 during sliding, such as Figure 12 As shown, the inner wall of the cover plate 118 may be provided with at least two abutting blocks 1183. The at least two abutting blocks 1183 are respectively located on opposite sides of the receiving groove 111, and the at least two abutting blocks 1183 abut against at least two sliding rods 141 to restrict the sliding rods 141 in the guide groove 1192. Through the cooperation between the guide groove 1192 and the abutting blocks 1183, the movement of the sliding rods 141 in other directions except for its sliding direction is restricted, thereby ensuring the stability and reliability of the structure when the sliding rods 141 slide.

[0081] like Figure 12 As shown, in addition to abutting the slide bar 141, the pressing block 1183 can also be assembled and fixed with the side plate 117 by screws to fully ensure the stability of the cover plate 118 after assembly.

[0082] In summary, in the hard disk bracket 100 provided in this application embodiment, after a receiving groove 111 for installing a hard disk 200 is provided on the base 110, a limiting member 120 is slidably provided through the opposite side walls of the receiving groove 111. By extending or retracting the limiting member 120 in the receiving groove 111, the hard disk 200 in the receiving groove 111 is fixed and released.

[0083] Based on this, in order to ensure that the hard drive 200 can be reliably installed and fixed on the hard drive bracket 100, an elastic member is provided that can extend toward the receiving groove 111 to the limiting member 120, so as to prevent the limiting member 120 from retracting due to tilting, shaking, etc., thereby preventing the hard drive 200 from falling off.

[0084] In addition, to facilitate the disassembly of the hard drive 200, a drive component 140 and a gear 130 are provided on the base 110. The limiting component 120 and the drive component 140 are driven by the meshing of the gear 130 with the rack (first rack 121 and second rack 1411). When force is applied to the drive component 140, the limiting components 120 on both sides can be moved away from the receiving groove 111 and retracted, so that the hard drive 200 can be easily and conveniently removed from the receiving groove 111.

[0085] According to another aspect of the embodiments of this application, a chassis is provided, the chassis including a chassis body and a hard disk tray 100 provided in any of the above embodiments, the hard disk tray 100 being disposed in the chassis body.

[0086] According to another aspect of the embodiments of this application, an electronic device is also provided, which may specifically be a server, a computer, etc. The electronic device includes a hard disk and a chassis provided in the above embodiments, with the hard disk disposed on a hard disk tray 100 inside the chassis.
