[0002] With the widespread adoption of mobile devices, portable hard drives, as a type of portable storage device, are widely used for data storage and transfer. However, existing portable hard drives typically only support single-device connections, such as connecting to a single terminal device like a mobile phone or computer for data reading and writing. This limitation restricts the application scenarios of portable hard drives, failing to meet users' needs for flexible use of storage devices in multi-device environments. For example, users cannot access data on a portable hard drive simultaneously on a mobile phone and tablet, or achieve seamless data sharing and synchronization in multi-device collaborative work scenarios. Therefore, existing portable hard drives have significant shortcomings in multi-device compatibility and application scenario expansion, limiting their application scope in modern digital life and office environments.

[0038] This utility model proposes a portable hard drive.

[0039] Please see Figures 1 to 4 In one embodiment of the present invention, the portable hard drive includes a first housing 10 and a second housing 20; one side of the second housing 20 is rotatably connected to one side of the first housing 10; an adsorption structure 30 is provided on the surface of one of the first housing 10 and the second housing 20, and a magnetic attraction structure 40 is provided on the surface of the other of the first housing 10 and the second housing 20; and a hard drive assembly is installed inside one of the first housing 10 and the second housing 20.

[0040] One side of the second housing 20 is rotatably connected to one side of the first housing 10. This rotatable connection design allows the first housing 10 and the second housing 20 to rotate relative to each other, thereby achieving different angle adjustments to adapt to different usage scenarios and user needs. For example, when used in a vehicle, the user can adjust the angle of the first housing 10 and the second housing 20 according to the driving perspective to achieve the optimal viewing position; when used on a desktop, the angle can also be adjusted according to the user's comfort.

[0041] An adsorption structure 30 is provided on the surface of one of the first housing 10 and the second housing 20. This adsorption structure 30 can be stably attached to any smooth surface, such as car windows, computer screens, and desktop glass, without the need for adhesive, thus avoiding damage to the surface of the object being attached. This design not only provides a stable fixation effect but also has the advantage of not damaging the surface of the object being attached, increasing the product's versatility and practicality. A magnetic structure 40 is provided on the other surface of the first housing 10 and the second housing 20. This magnetic structure 40 is a magnetic disc with strong adsorption properties. It can easily attach to magnetically attached mobile phones or magnetic metal surfaces. The combination of this magnetic structure 40 and the adsorption structure 30 allows the portable hard drive to meet different types of fixation needs simultaneously, achieving a stable fixation effect whether attached to a smooth surface or a magnetic object.

[0042] One of the first housing 10 and the second housing 20 houses a hard drive assembly. This hard drive assembly supports high-speed transmission of 10Gbps / 20Gbps, easily capturing and storing ProRes format videos, and can also be used as an external editing disk for video editing. Its capacity ranges from 256GB to 2TB, providing users with a variety of capacity options to meet the different needs of users for expanding their mobile phone storage. This high-speed solid-state drive configuration allows the portable hard drive not only to be used as a storage device, but also to play an important role in professional fields such as video shooting and editing, enhancing the product's functionality and applicability.

[0043] During use, the user can connect the first casing 10 to a computer via the adsorption structure 30 and simultaneously connect it to a mobile phone via the magnetic structure 40, thus enabling simultaneous viewing of both the computer and mobile phone, effectively using it as a stand. This dual connection method not only improves device stability but also allows users to conveniently view the content of two devices simultaneously while multitasking. Furthermore, this portable hard drive can also be used in in-vehicle infotainment systems, providing a convenient solution for phone mounting and storage in in-vehicle environments.

[0044] This portable hard drive also comes with a magnetic ring, making it compatible with mobile phones that lack magnetic attachment. With the assistance of the magnetic ring, even phones without magnetic attachment can connect to the portable hard drive's magnetic structure 40, further expanding the product's applicability and meeting the needs of more users.

[0045] This portable hard drive utilizes an adsorption structure 30 and a magnetic structure 40 respectively on the surfaces of the first housing 10 and the second housing 20, enabling simultaneous connection to two different types of terminal devices. For example, a user can fix the first housing 10 to a computer screen using the adsorption structure 30, while simultaneously connecting a mobile phone to the second housing 20 using the magnetic structure 40. This dual-connection method overcomes the limitation of traditional portable hard drives that only support single-device connections, enabling simultaneous use of different terminal devices such as mobile phones and computers, and meeting the user's need for flexible use of storage devices in multi-device environments.

[0046] In practical use, this portable hard drive significantly improves user efficiency in multi-device collaborative work scenarios. For example, in a car environment, users can fix the portable hard drive to the vehicle's infotainment system and connect it to their mobile phone for navigation or entertainment; in a desktop office setting, users can fix the portable hard drive to their computer and connect it to their mobile phone for data synchronization or file transfer. This multi-device compatibility not only meets the diverse needs of users in different scenarios but also enables seamless data sharing and synchronization, greatly enhancing the application value of portable hard drives in modern digital life and office environments.

[0047] In one embodiment, please refer to Figures 1 to 4 The adsorption structure 30 includes multiple suction cups 30a, which are arranged in an array at intervals.

[0048] These suction cups 30a are arranged in an array with intervals. This design is inspired by the structure of an octopus's suction cups 30a, mimicking their powerful suction and flexibility to achieve stable fixation of the portable hard drive on various smooth surfaces. The suction cups 30a are the core components of the adsorption structure 30, made of highly elastic and highly sealing materials, capable of tightly adhering to various smooth surfaces such as glass, metal, or plastic. Each suction cup 30a creates a negative pressure space, achieving firm adhesion by expelling air and applying external atmospheric pressure. The array of multiple suction cups 30a increases the adsorption area and stability, while also avoiding the risk of the entire drive detaching due to the failure of a single suction cup 30a.

[0049] During use, the user first aligns the suction structure 30 of the portable hard drive with the target surface, such as car glass or a computer screen. By gently pressing the suction cup 30a, the air inside the suction cup 30a is expelled, allowing it to adhere tightly to the surface and form a stable suction force. Because the suction cups 30a are arranged in an array, each suction cup 30a works independently, sharing the suction force, which allows the entire portable hard drive to be firmly fixed to the target surface. When it is necessary to move or remove the drive, the user simply needs to gently pull up the suction cup 30a, allowing the internal air to re-enter, the suction force to disappear, and the portable hard drive can be easily removed.

[0050] This adsorption structure 30 design brings significant technical benefits. First, the array arrangement of multiple suction cups 30a significantly enhances the adsorption force, allowing the portable hard drive to be stably fixed on various smooth surfaces, even under the bumps of a moving vehicle or slight vibrations from a tabletop. Second, the independent operation of the suction cups 30a improves system reliability; even if individual suction cups 30a are affected by dust or dirt, the others still function normally, ensuring that the overall adsorption performance is unaffected. Furthermore, this design eliminates the need for glue or adhesive materials, avoiding contamination and damage to the target surface, and offering excellent versatility and reusability.

[0051] In one embodiment, please refer to Figures 1 to 4 The other surface of the first housing 10 and the second housing 20 is recessed with a mounting groove, and the magnetic structure 40 is installed in the mounting groove; and / or, the magnetic structure 40 is a magnetic ring.

[0052] The mounting groove is a recessed structure on the surface of the second housing 20 used to fix the magnetic structure 40. Its design takes into account the size and shape of the magnetic structure 40, ensuring that it can be tightly embedded. The edges of the mounting groove are finely machined to prevent the magnetic structure 40 from loosening or falling off during use, while also providing a flat mounting platform for the magnetic structure 40, making it flush with the surface of the second housing 20, thus enhancing the overall aesthetics.

[0053] The magnetic structure 40 is one of the key components of the portable hard drive, used to attract magnetic objects (such as mobile phones or metal stands). In this embodiment, the magnetic structure 40 can be a magnetic ring. This design not only provides strong attraction but also has good compatibility, allowing it to be used with various devices that have magnetic attraction functions. The magnetic ring is made of high-performance magnetic material, has high magnetic flux density and good durability, and can maintain stable attraction performance even after repeated use.

[0054] During use, the cooperation between the magnetic structure 40 and the mounting slot ensures the stability and reliability of the magnetic function. When a user needs to connect the portable hard drive to a device with magnetic attraction (such as a mobile phone or car mount), they first align the magnetic structure 40 with the magnetic part of the device. Because the magnetic structure 40 is installed in the mounting slot, its position is fixed and flat, allowing for precise alignment with the magnetic part of the device. The ring-shaped design of the magnetic ring ensures even distribution of the attraction force, preventing damage or detachment of the device due to excessive local attraction.

[0055] This design delivers significant technological benefits. The combination of the mounting slot and the magnetic structure 40 makes the magnetic attraction function more stable and reliable. The magnetic ring design not only provides strong adhesion but also ensures compatibility with various devices, meeting users' needs in different scenarios. For example, in a car environment, users can fix the external hard drive to a car mount using the magnetic structure 40, maintaining stability even while the vehicle is in motion and preventing it from falling off due to bumps. When used on a desktop, users can fix their mobile phone to the external hard drive using the magnetic structure 40 for convenient video viewing or multitasking.

[0056] This design also enhances the versatility and portability of the portable hard drive. Thanks to the tight fit between the magnetic structure 40 and the mounting slot, the portable hard drive can be used flexibly in various scenarios, providing users with a stable and reliable storage solution, whether in a car, at a desktop, or for outdoor photography. Furthermore, the efficient magnetic attraction and excellent compatibility of the magnetic structure 40 allow the portable hard drive to seamlessly connect to a variety of devices, further expanding its application scenarios.

[0057] In one embodiment, please refer to Figures 1 to 4 The portable hard drive also includes a metal hinge 50, the two ends of which are connected to the first housing 10 and the second housing 20 respectively, so that the first housing 10 and the second housing 20 are rotatably connected.

[0058] In the portable hard drive design of this utility model, the metal hinge 50 is the core connecting component of the portable hard drive. Made of high-strength metal material, it possesses excellent durability and stability. It consists of several parts, including a first hinge plate 51, a second hinge plate 52, and a hinge 53 connecting the two. The design of the metal hinge 50 allows the first housing 10 and the second housing 20 to rotate freely within a certain angle range while maintaining structural stability. Furthermore, the metal hinge 50 also has a telescopic function, allowing adjustment according to different usage scenarios and device sizes. The first housing 10 and the second housing 20 are the main structural components of the portable hard drive, connected by the metal hinge 50 to form an integrated structure with adjustable angle and length.

[0059] During use, the telescopic and rotating functions of the metal hinge 50 provide the portable hard drive with a high degree of flexibility. Users can fix the portable hard drive in different positions by adjusting the length and angle of the metal hinge 50 according to their actual needs. For example, in a car environment, the user can attach the first housing 10 to the car window or dashboard, and by adjusting the length and angle of the metal hinge 50, align the magnetic structure 40 on the second housing 20 with a mobile phone or other device for stable fixation. When used on a desktop, the user can attach the portable hard drive to a computer screen or desktop stand, and by adjusting the metal hinge 50, place the mobile phone or other device in a suitable position for easy viewing and operation.

[0060] The telescopic function of the metal hinge 50 is achieved through its internal telescopic frame 54, which can freely extend and retract within a certain range while maintaining a stable connection with the first housing 10 and the second housing 20. The rotation function is achieved through the pivot 53, which allows the first housing 10 and the second housing 20 to rotate freely within a certain angle range, allowing users to adjust according to different usage scenarios and comfort requirements. Furthermore, the metal hinge 50 is equipped with a damping element that provides appropriate resistance, ensuring that the adjusted angle remains stable and does not easily change due to external forces.

[0061] The metal hinge 50 design brings significant technological benefits to the portable hard drive. Firstly, it grants the portable hard drive a high degree of flexibility and portability. Through the extension and rotation functions of the metal hinge 50, users can easily adjust the angle and length of the portable hard drive to suit different usage scenarios and device sizes, making it adaptable to various environments such as in-car use, desktop office work, and outdoor photography. This flexibility not only enhances the user experience but also significantly expands the applicability of the portable hard drive. Secondly, the high strength and stability of the metal hinge 50 ensure the reliability of the portable hard drive in various environments. The use of metal materials allows the hinge to withstand a certain amount of external impact while maintaining structural stability, preventing loosening or damage from frequent use. This durable design extends the product's lifespan and reduces user operating costs.

[0062] In one embodiment, please refer to Figures 1 to 4 The metal hinge 50 includes a first hinge plate 51, a second hinge plate 52, and a pivot portion 53. The first hinge plate 51 is connected to one of the first housing 10 and the second housing 20; the second hinge plate 52 is connected to the other of the first housing 10 and the second housing 20; the pivot portion 53 passes through the first hinge plate 51 and the second hinge plate 52 so that the first hinge plate 51 and the second hinge plate 52 are rotatably connected to the pivot portion 53 respectively.

[0063] The first hinge plate 51 is connected to either the first housing 10 or the second housing 20, while the second hinge plate 52 is connected to the other housing. A pivot 53 passes through both the first hinge plate 51 and the second hinge plate 52, allowing them to rotate flexibly around the pivot 53. This design not only achieves a rotatable connection between the first housing 10 and the second housing 20, but also significantly improves the flexibility, stability, and adaptability to various scenarios of the portable hard drive through its unique structure and function. The first hinge plate 51 is an important component of the metal hinge 50 and is typically made of high-strength metal to ensure its structural robustness and durability. One end of it is connected to the first housing 10 or the second housing 20 by welding or other fixing methods, forming a stable support point. The other end of the first hinge plate 51 is tightly fitted with the pivot 53, allowing it to rotate flexibly under the guidance of the pivot 53.

[0064] The second hinge plate 52, similar to the first hinge plate 51, is also made of high-strength metal. One end of it is connected to the other housing, and the other end engages with the pivot 53. The function of the second hinge plate 52 is to provide support for the other side of the portable hard drive and to work in conjunction with the first hinge plate 51 to enable the entire portable hard drive to rotate.

[0065] The hinge section 53 is the core component of the metal hinge 50. It runs through the first hinge plate 51 and the second hinge plate 52, serving a dual function of connection and rotation. The hinge section 53 is typically composed of a high-precision metal shaft and bearings, capable of withstanding certain pressure and torque while ensuring smooth rotation. The design of the hinge section 53 may also include a damping mechanism to provide appropriate resistance, allowing the portable hard drive to remain stable after angle adjustment.

[0066] In practical use, the components of the metal hinge 50 work together to enable the portable hard drive to rotate flexibly. When the user needs to adjust the angle of the portable hard drive, the first hinge plate 51 and the second hinge plate 52 rotate around the pivot 53. Due to the high-precision design of the pivot 53, the rotation process is very smooth, and the user can easily adjust the portable hard drive to the desired angle. For example, in a car environment, the user can attach the portable hard drive to the car window or dashboard, and by rotating the metal hinge 50, align the magnetic structure 40 on the second housing 20 with a mobile phone or other device for stable fixation. When used on a desktop, the user can attach the portable hard drive to a computer screen or desktop stand, and by adjusting the metal hinge 50, place the mobile phone or other device in a suitable position for easy viewing and operation.

[0067] In one embodiment, please refer to Figures 1 to 4 A first damping element is provided between the pivot portion 53 and the first folding plate 51; and / or, a second damping element is provided between the pivot portion 53 and the second folding plate 52.

[0068] A first damping element is provided between the pivot portion 53 of the metal hinge 50 and the first hinge plate 51, and / or a second damping element is provided between the pivot portion 53 and the second hinge plate 52. This design provides stable support and flexible adjustment capability for the rotation connection of the portable hard drive by introducing a damping mechanism between the pivot portion 53 and the hinge plate.

[0069] The function of damping components is to provide appropriate resistance during rotation, ensuring the stability of the portable hard drive after angle adjustment. Damping components typically consist of friction plates and elastic modules, achieving a damping effect on rotation through the combination of friction and elastic force. For example, a first damping component can be positioned between the rotating shaft 53 and the first hinge plate 51, while a second damping component can be positioned between the rotating shaft 53 and the second hinge plate 52. These components can work independently or in conjunction to meet different usage requirements.

[0070] In practical use, when the user needs to adjust the angle of the portable hard drive, the first hinge plate 51 and the second hinge plate 52 rotate around the pivot 53. At this time, the first and second damping components provide stable resistance to the rotation process through their internal friction plates and elastic modules. This resistance not only makes the rotation process smoother, but also maintains the state after adjustment to a suitable angle, preventing angle changes due to external forces (such as vibration or impact). For example, in a vehicle environment, even if the vehicle is bumpy, the portable hard drive can maintain a fixed posture and will not be affected by shaking.

[0071] By incorporating a damping element between the hinge 53 and the hinge plate, the user experience of the portable hard drive is significantly improved. First, the resistance provided by the damping element makes the rotation process smoother, allowing users to easily adjust the portable hard drive to the desired angle and maintain that position. Second, this design enhances the product's stability and reliability, especially in dynamic environments (such as in-vehicle or outdoor use). Finally, the introduction of the damping mechanism also enhances the product's durability, reducing mechanical wear caused by frequent adjustments. This design not only improves the functionality of the portable hard drive but also makes it perform excellently in various application scenarios, meeting users' diverse needs for portable storage devices.

[0072] In one embodiment, please refer to Figures 1 to 4 The first damping element includes a friction plate and a spring. The friction plate is located between the rotating shaft 53 and the first folding plate 51, and the two ends of the spring are connected to the friction plate and the first folding plate 51, respectively.

[0073] In the portable hard drive design of this utility model, a first damping element is provided between the pivot portion 53 of the metal hinge 50 and the first hinge plate 51. This damping element consists of a friction plate and a spring, used to achieve a damping effect and angle maintenance function during rotation. The friction plate is a key component of the damping mechanism, located between the pivot portion 53 and the first hinge plate 51. It is made of a material with a high coefficient of friction, capable of generating appropriate resistance during rotation, thereby achieving a damping effect. The design of the friction plate not only provides stable resistance but also maintains good performance after repeated use. The spring is another important component of the damping element, with its two ends connected to the friction plate and the first hinge plate 51, respectively. The function of the spring is to provide preload to the friction plate, ensuring that the friction plate and the pivot portion 53 always maintain close contact, thereby generating stable friction. The elastic characteristics of the spring can also buffer external impacts to a certain extent, extending the service life of the damping element.

[0074] In practical use, when the user needs to adjust the angle of the portable hard drive, the first hinge plate 51 rotates around the pivot 53. At this time, friction is generated between the friction plate and the pivot 53, providing stable resistance during rotation. The preload of the spring ensures that the friction plate and the pivot 53 maintain close contact, thus guaranteeing the stability of the friction. Once rotated to the desired angle, the friction keeps the first hinge plate 51 in that position, preventing it from easily changing angle even under slight external forces (such as vibration or impact). This design allows the portable hard drive to remain stable during use, making it particularly suitable for scenarios such as in-vehicle use and desktop office applications.

[0075] By incorporating a damping element consisting of a friction plate and a spring between the hinge 53 and the first hinge plate 51, the user experience of the portable hard drive is significantly improved. Firstly, the synergistic effect of the friction plate and spring provides stable resistance during rotation, resulting in smoother rotation and more precise angle adjustment. Secondly, this design enhances the product's stability and reliability, especially in dynamic environments such as in-vehicle or outdoor use, allowing the portable hard drive to maintain a fixed posture and preventing swaying from affecting its operation. Finally, the elastic properties of the spring also buffer external impacts, reducing mechanical wear caused by frequent adjustments and extending the product's lifespan. This design not only improves the functionality of the portable hard drive but also makes it perform exceptionally well in various application scenarios, meeting users' diverse needs for portable storage devices.

[0076] In one embodiment, please refer to Figures 1 to 4 The metal hinge 50 also includes a telescopic frame 54, which is movably connected to the second housing 20 and connected to the second hinge plate 52, so that the second hinge plate 52 is movably connected inside the second housing 20.

[0077] In the portable hard drive design of this utility model, the telescopic frame 54 is an important component of the metal hinge 50, used to achieve a movable connection between the second hinge plate 52 and the second housing 20. The design of the telescopic frame 54 not only provides flexibility in size adjustment but also ensures stability at different lengths. The second hinge plate 52 is connected to the telescopic frame 54, and its relative position with the second housing 20 is adjusted through the movement of the telescopic frame 54. This design allows the portable hard drive to be flexibly adjusted according to different usage scenarios and device sizes. The second housing 20 is one of the main structures of the portable hard drive, and a magnetic suction structure 40 or other functional components are installed inside. The telescopic frame 54, through its movable connection with the second housing 20, provides stable support for the second hinge plate 52.

[0078] In practical use, the telescopic bracket 54, through its internal telescopic mechanism, allows users to adjust its length according to their needs. When it is necessary to fix the portable hard drive to devices of different sizes, the user can stretch or compress the telescopic bracket 54 to change the distance between the second hinge plate 52 and the second housing 20, thereby achieving the best fixing effect. For example, in a vehicle environment, the user can stretch the telescopic bracket 54 to a suitable length to fix the portable hard drive to the dashboard or window; when used on a desktop, the user can adjust the telescopic bracket 54 according to the height of the device to ensure the stability of the portable hard drive.

[0079] By introducing the telescopic frame 54, the applicability and flexibility of the portable hard drive are significantly improved. First, the design of the telescopic frame 54 allows the portable hard drive to adapt to devices of various sizes, from small mobile phones to larger tablets, achieving stable fixation through adjustment of the frame. Second, this design enhances the product's portability; when not in use, the telescopic frame 54 can retract to its minimum length, reducing space occupation. Finally, the structural stability of the telescopic frame 54 ensures the reliability of the portable hard drive during use, maintaining a fixed posture even in dynamic environments (such as in a vehicle). This design not only improves the user experience but also enables the portable hard drive to better meet the diverse usage needs of modern digital life.

[0080] In one embodiment, please refer to Figures 1 to 4 The telescopic frame 54 includes a connecting plate 541 and a locking post 542. One end of the connecting plate 541 is movably connected to the second housing 20 and connected to the second folding plate 52. The connecting plate 541 is provided with a locking groove, and the edge of the locking groove is provided with locking teeth. The locking post 542 is connected to the second housing 20, and both ends of the locking post 542 elastically abut against the locking teeth.

[0081] In the design of this portable hard drive, the telescopic frame 54 provides flexible size adjustment for the metal hinge 50, mainly comprising two key components: a connecting plate 541 and a locking post 542. The connecting plate 541 is the core component of the telescopic frame 54, with one end movably connected to the second housing 20 and connected to the second hinge plate 52. The structural design of the connecting plate 541 allows it to slide within the second housing 20, thus achieving the telescopic function. The connecting plate 541 has a slot with locking teeth on its edge, used to engage with the locking post 542 for positioning. The locking post 542 is fixedly connected to the second housing 20, with both ends elastically abutting against the locking teeth on the connecting plate 541. The locking post 542 is designed with an elastic structure, providing stable resistance during the telescopic movement of the connecting plate 541, and achieving multi-level positioning through the locking teeth, ensuring the stability of the telescopic frame 54 at different lengths.

[0082] In practical use, when the user needs to adjust the length of the portable hard drive, they can slide the connecting plate 541 within the second housing 20 by pulling or pushing it. At this time, the elastic abutment of the locking pin 542 allows the connecting plate 541 to move smoothly, and the locking teeth will emit a slight "click" sound, indicating that the connecting plate 541 has reached a new positioning point. This elastic abutment design not only provides stable resistance but also ensures the stability of the telescopic frame 54 at different lengths.

[0083] Through the collaboration of the connecting plate 541 and the locking post 542, the telescopic frame 54 achieves flexible size adjustment, significantly improving the applicability and portability of the portable hard drive. This design not only allows users to adjust the length of the portable hard drive according to different usage scenarios (such as in-vehicle, desktop, or outdoor use), but also ensures the stability of the telescopic frame 54 through elastic engagement and multi-level positioning. Furthermore, the structural design of the telescopic frame 54 reduces mechanical wear, extends the product's lifespan, and further enhances the reliability and user experience of the portable hard drive in various scenarios.

[0084] In one embodiment, please refer to Figures 1 to 4 The locking post 542 includes a post body 542a and two elastic parts 542b. The two ends of the post body 542a are provided with countersunk holes. Each elastic part 542b is installed in a countersunk hole and elastically abuts against the locking teeth.

[0085] In the portable hard drive design of this utility model, the column 542a is the main body of the locking pin 542, and its two ends are designed with countersunk holes for installing the elastic part 542b. The main function of the column 542a is to provide structural support and to achieve the positioning function of the telescopic frame 54 through the interaction between the elastic part 542b and the locking teeth on the connecting plate 541. The elastic part 542b is installed in the countersunk holes at both ends of the column 542a and is usually made of elastic material, such as spring or elastic rubber. The function of the elastic part 542b is to provide elastic abutment between the locking pin 542 and the locking teeth, ensuring that the telescopic frame 54 can move smoothly during the extension and retraction process and provide stable positioning when needed. The countersunk holes are recessed structures at both ends of the column 542a to accommodate the elastic part 542b. The design of the countersunk holes allows the elastic part 542b to be embedded in them, preventing the elastic part 542b from shifting due to external forces during the extension and retraction process, thereby improving the stability and reliability of the structure.

[0086] During the use of the telescopic frame 54, when the user pulls or pushes the connecting plate 541, the locking teeth on the connecting plate 541 interact with the elastic part 542b of the locking post 542. The elastic part 542b provides elastic abutment within the countersunk hole, allowing the locking teeth to slide smoothly, thereby realizing the telescopic function of the telescopic frame 54. When the connecting plate 541 reaches the desired position, the elastic part 542b engages with the locking teeth, producing a slight "click" sound, indicating that the telescopic frame 54 has been positioned.

[0087] Through the cooperation of the locking post 542 and the elastic part 542b, the telescopic frame 54 achieves flexible telescopic function and reliable positioning capability. This design not only allows the portable hard drive to adapt to devices of different sizes, but also reduces mechanical wear through elastic contact, extending the product's lifespan. Furthermore, the countersunk hole structure further improves the stability and reliability of the telescopic frame 54, enabling it to maintain good performance in dynamic environments (such as in-vehicle or outdoor use). This structural design provides the portable hard drive with greater flexibility and applicability, meeting users' needs in various scenarios.
