Description

Technical Field

[0001] This application relates to the field of computer equipment technology, and in particular to a hard disk tray kit. Background Technology

[0002] Generally speaking, solid-state drives (SSDs) have become the mainstream technology in the current market, and the most commonly used hard drives are U.2 drives. However, with the upgrading of the central processing unit (CPU) in computer systems, which requires repeated calculations and higher processing speeds, thinner E3 hard drives have emerged, and the demand for these E3 hard drives is currently increasing.

[0003] The Enterprise and Datacenter Storage Form Factor (EDSFF), a standard designed specifically for enterprises and data centers, has gradually become the main trend in solid-state drive (SSD) form factors, aiming to provide superior performance, capacity, and heat dissipation. Within this standard, E3 drives can be broadly divided into E3.S and E3.L drives. Besides differences in performance and specifications, their lengths also differ: E3.S drives are 112.75 mm long, while E3.L drives are 142.2 mm long.

[0004] In order to effectively use and accommodate this type of slim E3 hard drive, a carrier that can better and more conveniently accommodate this type of slim E3 hard drive needs to be designed. Summary of the Invention

[0013] In one embodiment, the second side has two transition protrusions for abutting against one side of the second hard disk.

[0014] In one embodiment, the hard drive mounting bracket is C-shaped and includes two long arms and a bottom, with the two long arms respectively connected to the bottom, and the bottom connected to the mounting assembly.

[0015] In one embodiment, the fixing component further includes two fixing protrusions. When the fixing component is connected to the hard disk mounting bracket, the two fixing protrusions protrude from the bottom and are used to abut against one side of the first hard disk.

[0016] In one embodiment, the fixing component includes: a fixing base, in which the button assembly and the rotary handle assembly are rotatably disposed; and an elastomer, which covers the fixing base and is connected to the hard disk mounting bracket.

[0017] In one embodiment, the button assembly includes: a button for the user to press, wherein when the button assembly is in the locked position, the button presses against the rotary handle assembly; and a button resilient element connected between the button and the first side of the fixed assembly for providing the elastic force required when the button is pressed.

[0018] In one embodiment, the rotary handle assembly includes: a rotary handle, wherein when the rotary handle assembly is in the locked position, the button assembly presses against the rotary handle; and a handle elastic element connected between the rotary handle and the second side of the fixing assembly for providing the elastic force required for rotation when the rotary handle is released.

[0019] In one embodiment, the rotary handle assembly includes a slot that engages with the hard drive frame wall when the rotary handle assembly is in the locked position, and does not engage with the hard drive frame wall when the rotary handle assembly is in the released position.

[0020] In one embodiment, the hard drive bracket kit further includes a light guide post disposed within the fixing assembly, and the first hard drive also has at least one indicator light, wherein one end of the light guide post is close to the indicator light of the first hard drive, and the light guide post is used to conduct the light emitted by the indicator light to the outside of the fixing assembly.

[0021] The aforementioned hard drive bracket kit utilizes a structure including a hard drive mounting bracket, a mounting base, an elastomer, a button assembly, a rotating handle assembly, and an adapter bracket. Therefore, this invention can effectively connect to a thin hard drive using this structure. Attached Figure Description

[0039] Please refer to the following for comprehensive information. Figures 1 to 4 , Figure 1 An exploded view of the structure of the hard disk tray kit provided in a preferred embodiment of the present invention; Figure 2 This is a schematic diagram illustrating the assembly of the hard drive tray kit and the first hard drive according to a preferred embodiment of the present invention. Figure 3A schematic diagram showing the button assembly of the hard drive bracket kit provided in the preferred embodiment of the present invention in the locked position and the rotating handle assembly in the latched position; and Figure 4 This is a schematic diagram of the rotating handle assembly of the hard drive tray kit provided in a preferred embodiment of the present invention in the released position.

[0040] As shown in the figure, in order to connect with the currently required thin hard drives, the present invention provides a hard drive carrier kit 1, which is suitable for connecting with a first hard drive 2, such as an E3.L hard drive, and the first hard drive 2 has a first length L1. The hard drive carrier kit 1 includes: a hard drive fixing bracket 11, a fixing component, a button component 14, and a rotating handle component 15.

[0041] The hard drive mounting bracket 11 is used to connect to the first hard drive 2. The hard drive mounting bracket 11 can be C-shaped, but is not limited to this, and includes two long arms 111 and a base 112. The two long arms 111 are connected to the base 112, and the base 112 is connected to a fixing component. The two long arms 111 of the hard drive mounting bracket 11 are connected to the first hard drive 2 by at least one fixing element 113. The fixing element 113 can be, for example, an M3 screw or similar locking element, but is not limited to this.

[0042] The fixing assembly is used to connect to the hard drive mounting bracket 11. The fixing assembly also includes a fixing base 12 and an elastic body 13. The fixing base 12 is used to accommodate the button assembly 14 and the rotary handle assembly 15, and the button assembly 14 and the rotary handle assembly 15 are rotatably disposed within the fixing base 12.

[0043] The fixing base 12 of the fixing component also includes two fixing protrusions 125 (such as...). Figure 1 As shown), when the fixing assembly is to be connected to the hard drive mounting bracket 11, the two fixing protrusions 125 protrude from the bottom 112 and are used to abut against one side 21 of the first hard drive 2. The first hard drive 2 also has two first hard drive recesses 22 corresponding to the two fixing protrusions 125 (see reference). Figure 1 This is used to abut against the hard drive mounting bracket 11 and the two fixing protrusions 125 when the first hard drive 2 is to be connected to the hard drive mounting bracket 11. It should be further explained that the two sides of the first hard drive 2 are connected to the two long arms 111 of the hard drive mounting bracket 11 through fixing elements 113, while its other side 21 is fixed by abutting against the two fixing protrusions 125 of the fixing base 12 through two first hard drive grooves 22.

[0044] The elastomer 13 is used to cover the aforementioned fixed base 12, and is fixed to the bottom 112 of the hard disk mounting bracket 11 by a fixing element 115 (such as...). Figure 1 The hard drive mounting bracket 11, the elastomer 13, and the mounting base 12 are connected as shown in the diagram. The fixing element 115 can be, for example, an M3 screw or similar locking element, but is not limited to this. The elastomer 13 must comply with all relevant safety regulations, such as electromagnetic interference (EMI), electromagnetic compatibility (EMC), and electrostatic discharge (ESD) regulations.

[0045] The button assembly 14 is rotatably disposed within a fixed assembly, for example, within a fixed base 12, and located on the first side 121 of the fixed assembly. The button assembly 14 includes a button 141, a button resilient element 142, and a button rotation shaft 143. The button 141 is used by a user to press the button assembly 14 (e.g., ...). Figure 4 As shown), when the button assembly 14 is in the locked position (as shown) Figure 3 When (as shown), button 141 presses against the rotating handle assembly 15. A button elastic element 142 is used to connect button 141 to the first side 121 of the fixing base 12 of the fixing assembly, providing the elastic force required when button 141 is pressed. A button rotation shaft 143 connects button 141 to the fixing base 12 of the fixing assembly, allowing button 141 to be rotatably mounted on the first side 121 of the fixing assembly. The button elastic element 142 can be, for example, a spring or similar elastic element, but is not limited thereto.

[0046] The rotating handle assembly 15 is rotatably disposed within a fixed assembly, for example, within a fixed base 12, and located on a second side 122 of the fixed assembly, with the second side 122 relative to the first side 121. The rotating handle assembly 15 includes a rotating handle 151, a handle elastic element 152, and a handle rotation shaft 153. When the rotating handle assembly 15 is in a locked position (e.g., ...), Figure 3 When (as shown), the button 141 of the button assembly 14 presses against the rotary handle 151. The handle elastic element 152 is connected between the rotary handle 151 and the second side 122 of the fixing base 12 of the fixing assembly, and is used to provide the rotary handle 151 to be in the released position when it is released (as shown). Figure 4 The elastic force required for rotation (as shown) is generated. The handle rotation shaft 153 is connected to the rotating handle 151 and the fixed base 12 of the fixed assembly, so that the rotating handle 151 is rotatably disposed on the second side 122 of the fixed assembly. The handle elastic element 152 can be, for example, a spring or similar elastic element, but is not limited thereto.

[0047] In other words, the button assembly 14 and the rotating handle assembly 15 are riveted to the fixed base 12 by the button rotation shaft 143 and the handle rotation shaft 153, respectively, and the corresponding components are equipped with button elastic elements 142 and handle elastic elements 152, etc., so as to achieve the elastic rotation function required when pressing or releasing.

[0048] The rotary handle assembly 15 also includes a slot 154. When the rotary handle assembly 15 is in the aforementioned locked position, the slot 154 engages with the hard disk frame wall 4 (e.g., Figure 3 As shown, the hard drive bracket kit 1 of the present invention is used to engage with the hard drive frame 4, for example, it can be located inside the hard drive frame 4 inside the server. When the rotating handle assembly 15 is in the released position, the slot 154 and the hard drive frame 4 do not engage with each other, and the user can remove the hard drive bracket kit 1.

[0049] In addition, the fixing base 12 of the fixing component is designed with a first rotation limiting structure 123 and a second rotation limiting structure 124 on the first side 121 and the second side 122, respectively, to limit the rotation angle of the button assembly 14 and the rotary handle assembly 15 (e.g., Figure 3 ,as well as Figure 4 (As shown). The shapes of the first rotation limiting structure 123 and the second rotation limiting structure 124 need to match the shapes of the button assembly 14 and the rotary handle assembly 15, respectively. For example, they can be referenced to... Figure 3 ,as well as Figure 4 The structure shown is valid, but not limited to this structure.

[0050] The operation of the hard disk bracket kit 1 of the present invention is as follows: when the button assembly 14 is in the locked position, the button assembly 14 presses against the rotating handle assembly 15, causing the rotating handle assembly 15 to be in the locked position (e.g., Figure 3 (As shown in the diagram). When the user presses the button assembly 14, the button assembly 14 releases the rotating handle assembly 15, causing the rotating handle assembly 15 to be in the released position (as shown in the diagram). Figure 4 (as shown in the image).

[0052] As shown in the figure, the hard disk tray kit 1 of the present invention also includes a light guide column 16, which is disposed in the fixing base 12 of the fixing component, and at least one indicator light 23 is also provided on the side 21 of the first hard disk 2 (see reference). Figure 3 (Two light guides are shown in the figure) are used to display the actual operating status of the first hard drive 2. One end of the light guide 16 is close to the indicator light 23 of the first hard drive 2, and is used to guide the light emitted by the indicator light 23 to the outside of the fixing assembly. In addition, the light guide 16 also has an inverted clip structure 161, which is used to fix the light guide 16 inside the fixing base 12 of the fixing assembly. The structure of the light guide 16 is not limited to... Figure 5 Any structure that can achieve this related function can be the structure of the light guide post 16 as shown in the figure.

[0053] Please continue to consult the comprehensive reference. Figures 7 to 8 , Figure 7 A perspective view of the adapter bracket for the hard drive tray kit provided in a preferred embodiment of the present invention; and Figure 8 This is a schematic diagram illustrating the assembly of the hard drive bracket kit and the second hard drive, provided in a preferred embodiment of the present invention.

[0054] As shown in the figure, the hard drive bracket kit 1 of the present invention also includes an adapter bracket 17 having a first side 171 and a second side 172. The first side 171 is connected to the hard drive mounting bracket 11, and the second side 172 is used to connect to the second hard drive 3. The second hard drive 3 can be, for example, an E3.S hard drive. The second hard drive 3 has a second length L2, and the second length L2 is less than the first length L1. Thus, the hard drive bracket kit 1 can be selectively connected to the first hard drive 2 or the second hard drive 3.

[0055] The two sides of the adapter bracket 17 are the first side 171 (only one is shown in the figure) and are connected to the hard drive mounting bracket 11 by at least one fixing element 114 (see reference). Figure 8 (Only one is shown in the figure) is connected to two long arms 111. The fixing element 114 can be, for example, an M3 screw or similar locking element, but is not limited to this.

[0056] The second side 172 has two adapter protrusions 173 for abutting against one side of the second hard disk 3. The second hard disk 3 has two second hard disk grooves (not shown) corresponding to the two adapter protrusions 173, for abutting against the adapter bracket 17 when the second hard disk 3 is connected to it. Additionally, it can be noted that when the second hard disk 3 is connected to the two long arms 111 of the hard disk mounting bracket 11, the connection can be made using at least one fixing element 113 similar to the previous ones (e.g., ...). Figure 8As shown in the diagram, the two sides of the second hard disk 3 are connected to the two long arms 111 of the hard disk mounting bracket 11 by at least one fixing element 113, while the other side is fixed by the two adapter protrusions 173 of the adapter bracket 17 abutting against each other through the second hard disk groove.

[0057] In addition, the adapter bracket 17 also has two adapter grooves 174 corresponding to the two fixed protrusions 125 (e.g. Figure 7 As shown in the diagram, when the adapter bracket 17 is to be connected to the hard drive mounting bracket 11, the two fixing protrusions 125 of the hard drive mounting bracket 11 and the mounting base 12 abut against each other (as shown in the diagram). Figure 8 (as shown in the image).

[0058] By incorporating this adapter bracket 17 in the middle, the hard drive bracket kit 1 of the present invention can be used to selectively support the connection of either an E3.S hard drive or an E3.L hard drive.

[0059] It is worth noting that the structure of the hard drive bracket kit 1 of the present invention is described in the embodiment using E3.S hard drives and E3.L hard drives. However, in actual implementation of the structure of the present invention, it can also be implemented with other types or sizes of hard drives, and is not limited to E3 hard drives.

[0060] In summary, since the hard drive bracket kit 1 of the present invention utilizes a structure including a hard drive fixing bracket 11, a fixing base 12, an elastic body 13, a button assembly 14, a rotating handle assembly 15, and an adapter bracket 17, the present invention can indeed effectively connect to the thin first hard drive 2 and the second hard drive 3 through this structure.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
