Abstract
Description
Technical Field
[0001] This utility model relates to hard disk technology, and more particularly to a hard disk structure. Background Technology
[0002] As the mainstream data storage device, the hard disk drive (HDD) uses a read / write head to read and write data on a high-speed rotating disk.
[0003] Traditional hard drives are physically installed inside a computer case primarily by being secured to specially designed hard drive trays or drive bays with screws. The following are the detailed installation methods: The chassis has a dedicated metal hard drive bracket. The hard drive is aligned with the bracket via screw holes on the side or bottom, and then secured to the bracket with screws. Alternatively, the bracket may have built-in plastic clips or metal springs; pushing the hard drive into the bracket will automatically lock it in place.
[0004] Existing technologies include, for example, the latching mechanism proposed in Chinese patent application CN117340829A. In this patent, multiple latching components must be operated in a strict sequence, such as releasing the first latching component before operating the second latching component, and there is an interlocking relationship. During disassembly, incorrect operation sequence can easily lead to module jamming or component damage.
[0005] Furthermore, the first fastener relies on the sliding part to cooperate with the sliding groove. Long-term friction can easily lead to an increase in gap, inaccurate positioning, and inability to be stably locked in the preset position.
[0006] In conclusion, there is still a need to improve the existing technology. Utility Model Content
[0007] Based on the above-mentioned technical problems, this utility model proposes a hard disk structure that only requires pushing two semi-circular locking components to engage and lock together; pressing one of the levers releases the engagement of the two locking components in a coordinated manner.
[0008] The technical solution of this utility model is implemented as follows: A hard disk structure includes a first casing and a second casing, wherein a disk assembly is sealed and installed inside the first casing and the second casing. Its features are, An interface component is provided at one end of the first housing, and the interface component is connected to the interface socket via a snap-fit assembly. The latching assembly includes a first latching part and a second latching part. The first latching parts are mounted on both sides of the interface component, and the second latching parts are mounted on both sides of the interface seat. in, The first latching part includes a first latching body, and a first latching element is rotatably mounted on the middle of the first latching body. The second latching part includes a second latching body, and a second latching element is rotatably connected to the middle of the second latching body. Both the first and second fasteners are semi-circular structures that interlock with each other.
[0009] Preferably, a first lever is fixed to one end of the first buckle, and a first tension spring is provided between the first lever and the first buckle body.
[0010] Preferably, a second lever is provided at one end of the second buckle member, the second lever passes through the second buckle body and fits against both sides of the first outer shell, wherein a second tension spring is provided between the second buckle member and the second buckle body.
[0011] Preferably, the first and second fasteners are rotatably mounted on the first and second fastener bodies at a 30-60° angle, respectively.
[0012] Preferably, the first snap-fit body has an annular cavity in its middle, the first snap-fit element is located in the annular cavity, and one end of the annular cavity has a horizontal guide surface, which is flush with the center of the annular cavity. The annular cavity is provided with a pushing end at the end away from the horizontal guide surface, and the first buckle body is also provided with a first limiting end and a second limiting end.
[0013] Preferably, an inert gas is filled between the first outer shell and the second outer shell.
[0014] Preferably, the disk assembly includes a disk platter, a head arm, and a head, with a spindle motor mounted in the middle of the disk platter to drive its rotation.
[0015] Preferably, the magnetic head is mounted at one end of the magnetic head arm, and a voice coil motor for controlling the radial movement of the magnetic head is mounted at the end of the magnetic head arm away from the magnetic head.
[0016] The hard disk structure of this utility model has the following beneficial effects: Connecting the hard drive to the interface socket requires only a single step: pushing the hard drive towards the interface socket. During this movement, the pushing ends on the first and second locking parts automatically guide and rotate the opposing locking component, overcoming the tension of the spring and aligning it with the horizontal guide surface until it reaches the limit position. At this point, under the reset action of the spring, the first and second locking components automatically engage and lock together, completing the installation. The entire process requires no additional operation or tools.
[0017] During disassembly, simply press either the second or first lever. Pressing the second lever rotates the second latch, which in turn presses down on and drives the first latch to rotate synchronously, causing both to overcome the tension of their respective springs and rotate to a position flush with the horizontal guide surface. Once both semi-circular latches are disengaged, the hard drive can be easily removed from the interface socket. This avoids the cumbersome and error-prone nature of existing technologies that require operating multiple latches in a specific sequence.
[0018] The snap-fit assembly employs a structure where semi-circular snap-fit parts interlock and rotate. The design of the limiting end precisely restricts the final relative position of the snap-fit bodies, ensuring that the snap-fit parts are properly engaged, the connection is secure, and it is not easy for them to loosen or come loose.
[0019] The buckle uses a rotating connection instead of the sliding fit in existing technologies, which effectively avoids the problem of increased gap and misalignment caused by sliding friction during long-term use, and significantly improves the durability and long-term stability of the buckle mechanism.

Detailed Implementation
[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] Reference Figures 1 to 2 As shown, this utility model proposes a hard disk structure 100 that reads and writes data on a high-speed rotating disk using a read / write head.
[0023] It includes a control circuit board 101, a first housing 102, and a second housing 103. The control circuit board 101 is used to coordinate read and write operations, error correction (ECC), and data transmission. The disk assembly 20 is sealed and installed inside the first housing 102 and the second housing 103 and is filled with an inert gas, typically helium, to prevent the read / write head from colliding with dust.
[0024] The disk assembly 20 includes a disk platter 201, a head arm 202, and a head 203. The disk platter 201 is made of glass or aluminum alloy substrate and has a magnetic coating on its surface. It is generally made of 1-5 stacked platters and is used to store data.
[0025] A spindle motor 204 is installed in the middle of the disk 201 to drive the disk to rotate at high speed, with a speed of 5400 / 7200 RPM or 10000 / 15000 RPM.
[0026] The magnetic head 203 is mounted at one end of the head arm 202, supporting the movement of the magnetic head 203 above the disk 203. A voice coil motor 205 is mounted at the end of the head arm 202 away from the magnetic head 203, which is used to control the radial movement of the magnetic head 203.
[0027] The magnetic head 203 is an electromagnetic coil that changes the magnetism of the disk by using current to read and write data.
[0028] In this embodiment, an interface component 102A is provided at one end of the first housing 102, and the interface component 102A is electrically connected to the control circuit board 101. The interface component 102A is physically connected to the interface socket 30 via a snap-fit assembly 10.
[0029] Refer again Figures 3 to 5 As shown, the latching assembly 10 includes a pair of first latching parts 11 and second latching parts 12. The first latching parts 11 are installed on both sides of the interface component 102A, and the second latching parts 12 are installed on both sides of the interface seat 30.
[0030] The first latching part 11 includes a first latching body 111, and a first latching member 112 is rotatably mounted on the middle of the first latching body 111. A first lever 113 is fixed to one end of the first latching member 112, and a first tension spring 114 is provided between the first lever 113 and the first latching body 111.
[0031] The second latching part 12 includes a second latching body 121, and a second latching member 122 is rotatably connected to the middle of the second latching body 121. A second lever 123 is provided at one end of the second latching member 122, and the second lever 123 passes through the second latching body 121 and fits against both sides of the first outer shell 102. A second tension spring 124 is provided between the second latching member 122 and the second latching body 121.
[0032] Specifically, the first buckle 112 and the second buckle 122 are both semi-circular structures and are rotatably mounted on the first buckle body 111 and the second buckle body 121 at an angle of 30-60° respectively.
[0033] In this embodiment, refer again Figure 5 As shown, the structures of the first snap-fit body 111 and the second snap-fit body 121 are completely identical. Taking the first snap-fit body 111 as an example, an annular cavity 10A is provided in the middle of the first snap-fit body 111, and the first snap-fit member 112 is located in the annular cavity 10A. A horizontal guide surface 10B is provided at one end of the annular cavity 10A, and the horizontal guide surface 10B is flush with the center of the annular cavity 10A.
[0034] The annular cavity 10A has a push end 10C at the end furthest from the horizontal guide surface 10B. The first latching body 111 is also provided with a first limiting end 10D and a second limiting end 10E.
[0035] In this embodiment, refer again Figures 3 to 5 As shown, when the hard disk structure is snapped into place, the second snap-fit part 12 is pushed to move in the F1 direction.
[0036] During the movement, the pushing end 10C on the second latching body 121 will first push the first latching member 112 on the first latching body 111 to rotate in the F2 direction, making the first latching member 112 flush with its horizontal guide surface 10B. At the same time, the pushing end 10C on the first latching body 111 will also push the second latching member 122 on the second latching body 121 to be flush with its horizontal guide surface 10B.
[0037] Finally, the first limiting end 10D and the second limiting end 10E restrict the first locking body 111 and the second locking body 121 from moving further relative to each other. At this time, the first locking member 112 and the second locking member 122 are reset under the action of their respective tension springs, completing the mutual engagement. That is, Figure 4 The state shown.
[0038] When it is necessary to release the installation, manual operation is required. Press the second lever 123 in the F3 direction to rotate the second latch 122. At this time, the second latch 122 presses the first latch 112 to rotate synchronously until the second latch 122 and the first latch 112 are flush with the horizontal guide surface 10B, and then it can be unlocked.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
