Technical Field

[0001] This application relates to the field of electronic equipment technology, and more particularly to a mechanical hard disk. Background Technology

[0002] As a crucial data storage device, the hard disk drive (HDD) has a sophisticated internal structure, containing high-speed rotating disks and delicate read / write head assemblies. These components are extremely sensitive to vibration and shock; any unexpected vibration can lead to data read / write errors, damage to the read / write head, or even disk scratches, thereby affecting data integrity and hard drive reliability. Therefore, shock absorption measures are particularly important in the design, manufacturing, and transportation of HDDs.

[0003] During transportation and use, hard disk drives (HDDs) often encounter various complex and variable vibration environments. These environments may include impacts, vibrations, and combined vibrations from different directions, posing a serious challenge to the stability and safety of HDDs. Traditional shock absorption methods, such as those using screw-mounted structures, often prove inadequate in the face of these complex or harsh vibration environments. They cannot provide comprehensive, multi-angle protection for HDDs, thus increasing the risk of damage.

[0004] Traditional shock absorption methods, due to their limitations, often fail to meet the specific needs of different scenarios, thus limiting the application range and performance of mechanical hard drives. Utility Model Content

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0035] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0036] In some exemplary embodiments, such as Figures 1-6 As shown, a mechanical hard disk drive (HDD) includes a hard disk body 1, a casing 2, a locking member 3, and a shock-absorbing part 4. The hard disk body 1 is used for data storage. The HDD has a thickness direction (see reference). Figure 1 The Z-axis (as shown), the first direction (refer to) Figure 1 The X-axis (as shown) and the second direction (refer to) Figure 1 The thickness direction, the first direction, and the second direction are perpendicular to each other, providing a reference for subsequent assembly and component arrangement.

[0037] The shell portion 2 is fitted onto the outside of the hard disk body 1 to protect it. The shell portion 2 may include, for example, a first shell 21 and a second shell 22, which are located on opposite sides along the thickness direction of the hard disk. The first shell 21 and the second shell 22 are positioned opposite each other, forming a protective space between them to accommodate the hard disk body 1, which is connected to the first shell 21.

[0038] The casing 2 is provided with an accommodating space to surround the hard drive body 1, protecting it from external impacts and improving the safety of the hard drive. The casing 2 may have an upper end face 24 and a lower end face 25 arranged opposite each other along its thickness direction, two first side walls 26 arranged opposite each other along a first direction, and two second side walls 27 arranged opposite each other along a second direction. The upper end face 24, lower end face 25, first side walls 26, and second side walls 27 can be fully enclosed to protect the hard drive body 1 from all directions. Openings can be provided in either the first or second side walls 26 to facilitate the installation of the hard drive body 1. For example, the first side wall 26 may have an opening 23 to facilitate the placement or removal of the hard drive body 1, with the opening 23 being slightly larger than the hard drive body 1 to ensure it can pass through normally, facilitating installation and removal. The second direction may be the width direction of the casing 2. While ensuring the hard drive body 1 can be installed normally, the size of the opening 23 should be minimized to avoid compromising the structural strength of the casing 2. It should be noted that the aforementioned opening 23 can be set to one or two, thereby improving the flexibility of operation.

[0039] The casing 2 includes a first casing 21 and a second casing 22, which surround at least a portion of the structure of the hard disk body 1 to protect it. For example, the first casing 21 and the second casing 22 are arranged opposite each other, that is, on opposite sides in the thickness direction of the hard disk, forming an accommodating space between the first casing 21 and the second casing 22 to accommodate the hard disk body 1 and provide protection for the hard disk body 1. They are fixed together by suitable means, such as screw connections, snap-fit ​​connections, etc., to improve the reliability of the connection.

[0040] For example, the first housing 21 includes a first housing body 211 and two first side wings 212. The two first side wings 212 are symmetrically arranged along the first direction of the hard disk drive, and the first side wings 212 are bent relative to the first housing body 211, so that the first side wings 212 and the first housing body 211 form a preset angle, such as, but not limited to, 90°. The first housing body 211 can shield and protect the sidewalls of the hard disk body 1 in the thickness direction, and the first side wings 212 protect the two sidewalls of the hard disk body 1 along the first direction of the hard disk drive, reducing the risk of damage caused by external impact.

[0041] The second housing 22 includes a second housing body 221 and two second side wings 222. The structure of the second housing 22 is the same as or similar to that of the first housing 21, and will not be repeated here. The dimension of the second housing 22 along the second direction of the hard disk is larger than that of the first housing 21, such that the second side wings 222 are located on the side of the first side wings 212 away from the hard disk body 1.

[0042] The first housing 21 and the second housing 22 are disposed opposite to each other and spaced apart. The first housing body 211 and the first side wing 212 of the first housing 21, and the second housing body 221 and the second side wing 222 of the second housing 22 together enclose an accommodating space. The dimension of the second housing 22 along the second direction of the hard disk is larger than the dimension of the first housing 21. The projection area of ​​the second side wing 222 along the second direction of the hard disk can overlap with the projection area of ​​the first side wing 212 along the second direction of the hard disk to facilitate a fixed connection between the first housing 21 and the second housing 22.

[0043] The hard drive body 1 is connected to the first housing 21. For example, the hard drive body 1 is connected to the first side support 222 of the first housing 21, and the hard drive body 1 and the first housing body 211 are spaced apart to reduce direct contact and prevent vibrations on the first housing body 211 from being transmitted to the hard drive body 1, thus affecting the performance of the hard drive body 1. It can be understood that the hard drive body 1 and the second housing body 221 of the second housing 22 are also spaced apart, so that the hard drive body 1 is suspended on both sides, reducing the vibration impact of the housing part 4 on the hard drive body 1 along the thickness direction.

[0044] In this embodiment, as Figure 1 As shown, multiple shock-absorbing parts 4 are disposed on both sides of the hard disk body 1 along a first direction. For example, the shock-absorbing parts 4 are disposed on the second side wall 27 of the housing 2 to facilitate shock absorption of the hard disk body 1.

[0045] The multiple shock-absorbing parts 4 can be arranged sequentially at intervals along the first direction, allowing for flexibility in their placement. Alternatively, the shock-absorbing parts 4 can be arranged symmetrically in pairs along the first direction of the hard drive, so that the shock-absorbing directions of the two sides of the shock-absorbing parts 4 coincide, further improving the shock absorption effect. For example, the first direction can be the length direction of the hard drive, allowing the shock-absorbing parts 4 to be arranged along the length direction of the hard drive, further enhancing the shock absorption capability.

[0046] In this embodiment, as Figures 1-6 As shown, the damping part 4 includes a damping body 41 and a damping support 42. The damping body 41 and the damping support 42 can be integrally formed to improve the strength and reliability of the damping part 4.

[0047] The shock-absorbing body 41, for example, is made of soft rubber material. Soft rubber material possesses good elasticity, flexibility, and wear resistance. These properties allow the shock-absorbing body 41 to effectively absorb and disperse external impact forces, thereby protecting the hard drive body 1 from damage. Furthermore, the soft rubber material also has a certain sound insulation effect, reducing the noise generated by the hard drive during operation and improving the user experience. In practical applications, the shock-absorbing body 41 made of soft rubber significantly improves the shock resistance of the hard drive. Even in harsh environments such as bumps or impacts, the hard drive can maintain normal operation, effectively ensuring data security. It is understood that the shock-absorbing support 42 can also be made of soft rubber material, achieving the same function as the shock-absorbing body 41; therefore, it will not be repeated here.

[0048] The second housing 22 is connected to the first housing 21 via the shock-absorbing body 41. The shock-absorbing support 42 is disposed on the side of the shock-absorbing body 41 and is connected to the second housing 22. Exemplarily, the shock-absorbing body 41 can be connected to the first housing 21 and the second housing 22 via, but not limited to, an adhesive layer, and the shock-absorbing support 42 can also be connected to the second housing 22 via, but not limited to, an adhesive layer, which is simple and easy to operate.

[0049] The damping direction of the damping body 41 is parallel to the second direction, and the damping direction of the damping support 42 is perpendicular to the second direction. For example, since the damping support 42 is located on the side of the damping body 41, a mutually restraining force is generated between the damping body 41 and the damping support 42. The direction of this mutually restraining force is parallel to the second side wall 27 of the shell 4, and the second side wall 27 is perpendicular to the second direction, thereby satisfying the damping requirements of the hard disk in different directions.

[0050] The damping support 42 can be one or more to achieve multiple damping directions and further improve the damping effect. For example, the damping support 42 includes multiple sub-supports, which are connected to the damping body 41 respectively. The multiple sub-supports are arranged sequentially along the circumference of the damping body 41 to construct multiple damping directions, which can be compared with omnidirectional damping. The following is an illustration using two sub-supports as an example to facilitate further understanding.

[0051] First Example

[0052] The damping support 42 includes a first sub-support 421 and a second sub-support 422, which are respectively connected to the damping body 41 to ensure the stability of the damping performance.

[0053] The first sub-support 421 and the second sub-support 422 are symmetrically arranged along one of the centerlines of the damping body 41. This not only helps to evenly distribute the damping force and improve the damping efficiency, but also effectively reduces the risk of structural deformation or damage caused by uneven stress. This centerline, for example, is aligned with the thickness direction of the hard disk drive.

[0054] Second example

[0055] The first sub-support 421 is located on the first centerline of the shock-absorbing body 41, and the second sub-support 422 is located on the second centerline of the shock-absorbing body 41. The first and second centerlines are perpendicular to each other; for example, the first centerline aligns with the thickness direction of the hard drive, and the second centerline aligns with the first direction of the hard drive.

[0056] This mutually perpendicular layout design is designed to cope with vibrations and impacts from specific directions. By dispersing the damping force in different directions, it achieves more precise vibration control. For example, in some applications, a hard drive may be mainly affected by vibrations from a specific direction. In this case, arranging the first sub-support 421 and the second sub-support 422 on mutually perpendicular centerlines can more effectively absorb and disperse this vibration energy, thereby protecting the hard drive from damage.

[0057] It should be noted that the above-mentioned damping support 42 is not limited to setting two sub-supports to form a restriction on both sides of the damping body 41. Three, four or more can also be set. The four sub-supports can be set symmetrically in pairs to achieve multi-directional or all-directional damping and ensure the stability of the damping performance of the damping part 4.

[0058] In this embodiment, the hard disk drive (HDD) is equipped with a shock-absorbing section 4 to provide buffering and shock absorption, thereby improving the HDD's safety. The shock-absorbing section 4 can provide multi-directional buffering and shock absorption, meeting the shock absorption requirements in different directions, improving the HDD's safety factor, extending its service life, and reducing the risk of data loss due to external impacts.

[0059] In some exemplary embodiments, such as Figure 1 As shown, the shock-absorbing part 4 also includes a first locking member 43, which is provided in a one-to-one correspondence with the shock-absorbing body 41. The first locking member 43 can rotatably pass through the shock-absorbing body 41 and the first housing 21, and is connected to the hard disk body 1, improving the stability during connection.

[0060] In some examples, the first locking member 43 is, for example, a fixing post. One end of the fixing post can pass through the shock-absorbing body 41 and the first housing 21 in sequence and be inserted into the hard disk body 1. The hard disk body 1 is provided with a fixing hole, and the fixing post and the fixing hole are interference-fitted to achieve a fixed connection.

[0061] In other examples, the first locking element 43 is, for example, a screw, and the hard disk body 1 is provided with a screw hole that mates with the screw. One end of the screw can pass through the shock-absorbing body 41 and the first housing 21 in sequence and be threaded into the screw hole, thereby improving the stability of the connection.

[0062] The shock-absorbing body 41 has a first groove 411, and the bottom wall of the first groove 411 is provided with a first through hole 412. The inner diameter of the first through hole 412 is smaller than the inner diameter of the first groove 411. The first through hole 412 is configured to accommodate a corresponding first locking member 43.

[0063] The first side support 212 is provided with a second through hole 213, the hard disk body 1 is provided with a hard disk connection hole 11, and one end of the first locking member 43 rotatably passes through the first through hole 412 and the second through hole 213 of the first groove 411 and connects with the hard disk connection hole 11.

[0064] The first locking member 43 presses the shock-absorbing part 4 onto the shell part 2. This connection method not only ensures a tight connection between the hard drive body 1 and the shell part 2, but also applies appropriate pressure to the shock-absorbing part 4 through the first locking member 43, making it fit more firmly onto the shell part 2, thereby achieving an effective shock absorption effect.

[0065] The second through hole 213 is located on the bottom wall of the positioning groove 214, providing a path for the first locking member 43 to pass through. The first locking member 43 passes through the second through hole 213 and connects to the hard drive connection hole 11 of the hard drive body 1. The first locking member 43 securely connects the hard drive body 1 to the first housing 21, while the shock-absorbing body 41 remains stable under the constraint of the positioning groove 214.

[0066] In this embodiment, as Figure 1 As shown, the damping part 4 also includes a second locking member 44, the number of which is related to the damping support 42. The second locking member 44 rotatably passes through the damping support 42 and is connected to the second housing 22.

[0067] For example, the shock absorber support 42 includes a first sub-support 421 and a second sub-support 422, each with a second groove 423. The bottom wall of the second groove 423 has a second through hole 424, the inner diameter of which is smaller than that of the second groove 423. The second through hole 424 is configured to accommodate a corresponding second locking member 44. Part of the second locking member 44 is housed within the second through hole 424, while another part is housed within the second groove 423, thus limiting the movement of the second locking member 44 and preventing it from passing through the shock absorber 4, which would prevent the shock absorber 4 and the first housing 21 from being synchronously fixed.

[0068] The shock-absorbing support 42 is connected to the second side support 222 of the second housing 22 via a corresponding second locking member 44. The second side support 222 of the second housing 22 is provided with multiple first connecting holes 223, each corresponding to a first sub-support 421 and a second sub-support 422, allowing the second locking member 44 to pass through the corresponding shock-absorbing support 42 (i.e., the first sub-support 421 and the second sub-support 422) and connect to the first connecting hole 223. When the second locking member 44 is a screw, the first connecting hole 223 becomes a corresponding screw hole, enabling a screw connection and improving the reliability of the connection.

[0069] A first reinforcing rib 224 is provided on the wall of the second side support 222 of the second housing 22 near the hard disk body 1. The first reinforcing rib 224 is arranged circumferentially along the second locking member 44. Specifically, the first reinforcing rib 224 surrounds the first connecting hole 223. The first reinforcing rib 224 is, for example, annular, to surround the first connecting hole 223, improve the strength at the location of the first connecting hole 223, and avoid the problem of insufficient structural strength caused by the opening.

[0070] In some exemplary embodiments, such as Figures 1-6 As shown, the second side support 222 of the second housing 22 is provided with a plurality of through holes 225. The damping body 41 of the damping part 4 corresponds one-to-one with the through holes 225. One end of the damping body 41 is connected to the first housing 21, and the other end of the damping body 41 can pass through the through hole 225. The damping body 41 is locked in the through hole 225, so that the damping body 41 and the second housing 22 form a limiting connection.

[0071] The shock-absorbing body 41 can pass through the through hole 225, and the shock-absorbing support 42 is located on the side of the second housing 22 away from the first housing 21. The shock-absorbing support 42 is effectively intercepted by the second side support wing 222, thereby preventing the shock-absorbing part 4 from falling off the housing 2 when subjected to external force, and ensuring the stability and reliability of the shock-absorbing part 4 in the hard drive.

[0072] The axial dimension of the shock-absorbing body 41 is larger than that of the shock-absorbing support 42, so that the shock-absorbing body 41 has sufficient length to pass through the corresponding through hole 225 and form a tight abutment with the first housing 21. This abutment not only enhances the fixing effect of the shock-absorbing body 41, but also helps to improve the overall shock resistance of the mechanical hard drive.

[0073] For example, the shock-absorbing body 41 of the shock-absorbing part 4 can be bonded to the second housing 22 to improve the reliability of the connection. Alternatively, the shock-absorbing body 41 of the shock-absorbing part 4 can be positioned and connected to the second housing 22. For example, the first side support 212 of the first housing 21 is provided with a plurality of positioning grooves 214. The number, position and shape of the positioning grooves 214 correspond one-to-one with the shock-absorbing part 4. The positioning grooves 214 are configured to accommodate the corresponding shock-absorbing body 41, that is, one end of the shock-absorbing body 41 is embedded in the positioning groove 214. This not only ensures the accuracy of the shock-absorbing part 4 during installation, but also helps to improve the overall shock resistance of the hard drive. Furthermore, the shock-absorbing body 41 can also be interference-fitted with the positioning groove 214 to further achieve a tight connection between the second housing 22 and the shock-absorbing body 41.

[0074] In some exemplary embodiments, such as Figures 1-6 As shown, the mechanical hard drive also includes multiple auxiliary shock absorbers 5, which are located on the side of the second housing 22 away from the hard drive body 1. That is, the auxiliary shock absorbers 5 are connected to the second housing body 221 of the second housing 22, which helps to further disperse and absorb the impact force from the outside and improve the overall shock resistance of the mechanical hard drive.

[0075] Among them, there are four auxiliary shock-absorbing components 5, which are set along the four corners of the second shell body 221. This not only ensures that the hard drive is fully protected in the four key parts, but also maintains the overall stability and balance of the hard drive.

[0076] In this embodiment, as Figures 1-6 As shown, the auxiliary shock absorber 5 is positioned between two symmetrically arranged shock absorber parts 4. The shock absorption direction of the auxiliary shock absorber 5 is consistent with the thickness direction of the hard drive. The auxiliary shock absorber 5 and the shock absorber parts 4 achieve omnidirectional shock absorption, improving the shock absorption effect and adapting to different application scenarios.

[0077] In this embodiment, as Figures 1-6 As shown, the auxiliary shock absorber 5 includes an auxiliary shock absorber 51 and a locking body 52. ​​The locking body 52 is connected to the second housing body 221 of the second housing 22 via the auxiliary shock absorber 51. The auxiliary shock absorber 51 is responsible for absorbing and dispersing impact forces. The auxiliary shock absorber 51 is made of, for example, soft rubber, which gives it good elasticity and flexibility, enabling it to effectively absorb external impact forces and protect the hard drive from damage.

[0078] The locking body 52 securely connects the auxiliary shock absorber 51 to the second housing body 221 of the second housing 22. The design of the locking body 52 should ensure the stability and reliability of the connection to prevent loosening or detachment during transportation or use.

[0079] For example, the locking body 52 includes a baffle 521, an extension rod 522, and a screw 523 connected in sequence. The second housing body 221 of the second housing 22 is provided with a third connecting hole 226. The auxiliary shock absorber 51 is provided with a third through hole 511. One end of the locking body 52 passes through the third through hole 511 and is connected to the third connecting hole 226, that is, the screw 523 is screwed to the third connecting hole 226. The extension rod 522 is placed in the third through hole 511. The baffle 521 is located on the side of the auxiliary shock absorber 51 away from the hard disk body 1, so that the auxiliary shock absorber 51 is pressed on the second housing body 221, thereby achieving an effective shock absorption effect.

[0080] The auxiliary shock absorber 51 is, for example, cylindrical in shape, and both ends of the auxiliary shock absorber 51 are provided with multiple protrusions 512. The multiple protrusions 512 are evenly distributed along the circumference of the auxiliary shock absorber 51, which can not only provide support, but also further disperse and absorb the impact force from the outside, thereby improving the overall shock resistance of the mechanical hard drive.

[0081] In practical applications, the mechanical hard drive provided in this application is equipped with a shock-absorbing part 4 and an auxiliary shock-absorbing part 5. The auxiliary shock-absorbing part 51 is mainly used for shock absorption in the axial direction, while the shock-absorbing part 4 is used for shock absorption in all directions, which significantly improves the shock resistance of the mechanical hard drive. Even when encountering harsh environments such as bumps and impacts, the mechanical hard drive can maintain normal operation, and data security is effectively guaranteed.
