Description

Technical Field

[0001] This utility model relates to the field of storage device technology, and specifically to a portable hard drive designed to prevent loss. Background Technology

[0002] With the miniaturization and widespread adoption of portable storage devices, external hard drives are more prone to accidental loss during transport due to their compact size. Current mainstream external hard drives use a metal casing to encapsulate the circuit board. Due to the electromagnetic shielding effect of metal, the built-in locator signal cannot penetrate the casing to be transmitted to external devices. Users typically use external Bluetooth trackers to enhance tracking. However, external accessories require independent power supplies and rely on adhesives or clips for fixation, which not only increases the device's size and reduces portability but also leads to problems such as short battery life and easy loss. Therefore, existing external hard drives suffer from incompatibility between the metal casing and built-in positioning function, and insufficient reliability of anti-loss features. Utility Model Content

[0003] The purpose of this utility model is to provide a lost-proof portable hard drive to solve the problems of incompatibility between the metal casing and built-in positioning function of existing portable hard drives and the low reliability of the lost-proof function.

[0004] To achieve the above objectives, the present invention provides a loss-proof portable hard drive using the following technical solution: A loss-proof portable hard drive includes: a metal casing, the side wall of which has at least one non-metallic wave-transparent portion made of a wave-transparent engineering material; a circuit board fixedly disposed in the inner cavity of the metal casing; a storage module disposed on the circuit board; a data interface disposed on the circuit board and electrically connected to the storage module; a locator chip disposed on the circuit board for generating a positioning signal; a battery disposed on the circuit board and electrically connected to the locator chip; and a communication antenna disposed on the non-metallic wave-transparent portion, the radiator of which is tightly attached to the non-metallic wave-transparent portion and electrically connected to the locator chip.

[0005] As an optimization for preventing loss of portable hard drives, the non-metallic transparent part is a transparent side cover, which is fixedly connected to the side wall of the metal casing.

[0006] As an optimization for preventing loss of portable hard drives, the transparent side cover has a transparent bulge protruding outward, and the communication antenna is embedded in the transparent bulge.

[0007] As an optimization for preventing loss of a portable hard drive, the non-metallic transparent section is a transparent window disposed on the side wall of the metal casing, and the transparent window is covered with a non-metallic transparent sheet.

[0008] As an optimization for preventing loss of portable hard drives, the wave-transparent engineering material is LDS plastic, ceramic, or glass fiber reinforced polyester resin.

[0009] As an optimization for preventing loss of portable hard drives, the battery is a rechargeable battery, and the battery is electrically connected to the data interface.

[0010] As an optimization for preventing loss of portable hard drives, the data interface includes a Type-C interface, a Micro USB interface, or a Lightning interface.

[0011] As an optimization for preventing loss of portable hard drives, one side of the circuit board is provided with an M.2 interface, into which the storage module is plugged; the other side of the circuit board is provided with a T-nut and an M.2 screw, with the M.2 screw screwed into the T-nut to tighten and fix the storage module.

[0012] As an optimization for preventing loss of portable hard drives, the locator chip includes a Bluetooth positioning chip, a GPS positioning chip, a Beidou positioning chip, a UWB positioning chip, or a cellular network positioning chip.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) Overcoming the limitations of metal shielding: By setting non-metallic wave-transparent parts such as wave-transparent side covers or wave-transparent windows on the side wall of the metal shell, and using low-loss wave-transparent materials such as LDS plastic and ceramics, the radio frequency signal generated by the locator chip can effectively penetrate the shell, solving the problem of electromagnetic shielding of the positioning signal by the metal shell and realizing the compatibility between the metal shell and the built-in positioning function.

[0022] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail below.

[0023] This application provides a loss-proof portable hard drive, employing the following technical solution: Reference Figure 1 and Figure 2The anti-loss portable hard drive includes a metal casing 1, a circuit board 3, a storage module 4, a data interface 5, a locator chip 6, a battery 7, and a communication antenna 8. The metal casing 1 is made of aluminum alloy, and its outer surface is sandblasted to create a rough texture with Ra=3.2-6.3μm, increasing the coefficient of friction and effectively preventing slippage. The metal casing 1 is a hollow cuboid with rectangular top and bottom surfaces and narrow sidewalls. Each sidewall of the metal casing 1 has at least one non-metallic wave-transparent section 2. In this embodiment, each of the four sides of the metal casing 1 has one non-metallic wave-transparent section 2. The non-metallic wave-transparent section 2 is made of a wave-transparent engineering material. This wave-transparent engineering material is tested in the 2.4GHz Bluetooth band, and its electromagnetic wave penetration loss is ≤3dB. Specifically, the wave-transparent engineering material includes, but is not limited to, LDS (Laser Direct Structuring) plastic, ceramic, or glass fiber reinforced polyester resin. Circuit board 3 is fixedly mounted to the inner cavity of metal housing 1 with screws. Storage module 4, data interface 5, locator chip 6, and battery 7 are all integrated and soldered onto circuit board 3, and are electrically connected through the circuit on circuit board 3. Among them, storage module 4 is a solid-state storage chip with M.2 interface 31 of specification 2242 or 2280. Data interface 5 includes, but is not limited to, Type-C interface, Micro USB interface or Lightning interface. Data interface 5 is electrically connected to storage module 4 to realize the data storage function of mobile hard drive. The locator chip 6 realizes position tracking by generating and modulating radio frequency signals. The positioning chip includes, but is not limited to, Bluetooth positioning chip, GPS positioning chip, Beidou positioning chip, UWB positioning chip or cellular network positioning chip. Battery 7 directly provides continuous power to locator chip 6 independently of data interface 5. Furthermore, locator chip 6 is configured in low power mode, entering a low power state when not accessed by host device through communication terminal, so that static operating current ≤10μA. Furthermore, the battery 7 is a rechargeable battery, which is electrically connected to the data interface 5 through a charging management circuit. When the portable hard drive is connected to the host device to transmit data, the charging management circuit automatically charges the battery 7 after rectification and voltage regulation of the input power, realizing the synchronization of data transmission and battery charging. The communication antenna 8 is installed in the non-metallic transparent part 2. Its structure is a spiral wire or etched circuit. It extends the current path in a limited space by spiral or tortuous arrangement, realizing the balance between miniaturization and omnidirectional radiation. The radiator of the communication antenna 8 is closely attached to the non-metallic transparent part 2. The specific attachment methods include embedding it in the transparent material, attaching it to the outer surface, or sandwiching it between the layered structures. It is connected to the RF port of the locator chip 6 through signal lines 81 such as microstrip lines or coaxial feed lines, so that the positioning signal penetrates the non-metallic transparent part 2 and radiates to the external space.

[0024] Through the above structure, the non-metallic wave-transmitting part 2 effectively overcomes the electromagnetic shielding limitation of the metal shell, controls the penetration loss of the positioning signal to within 3dB, and completely solves the core problem that the built-in locator signal cannot be transmitted externally; at the same time, the close fit design between the radiator and the wave-transmitting part improves the antenna efficiency and ensures stable transmission of long-distance positioning signals; in addition, the independent power supply system of the battery 7 and the low power mode work together to reduce the static operating current to below 10μA, realize long-term continuous standby tracking capability, and fundamentally eliminate the battery life defects of external trackers.

[0025] In a preferred embodiment of this application, reference is made to Figure 1 and Figure 2 The specific structure of the non-metallic wave-transparent part 2 is a wave-transparent side cover 21. The wave-transparent side cover 21 is installed on one side of the metal housing 1. The end of the wave-transparent side cover 21 is bonded and fixed to the side wall of other metal housing 1. On the one hand, the metal housing 1 can be disassembled to inspect the internal circuit board 3. On the other hand, a wave-transparent area is independently formed on the side of the metal housing 1 so that the signal generated by the positioner can be transmitted to the outside.

[0026] Furthermore, referring to Figure 1 and Figure 2 The translucent side cover 21 protrudes outward to form a translucent convex 211 that is sealed with the housing. The radiator of the communication antenna 8 is embedded therein, so that the antenna radiation pattern is not blocked by the metal housing 1, thereby improving the omnidirectional signal coverage capability. The height of the translucent convex 211 is 1.2±0.3mm, and its length and width dimensions match the resonant frequency of the radiator.

[0027] In the preferred embodiment of this application, reference is made to Figure 1 and Figure 2 The specific structure of the non-metallic wave-transmitting part 2 is a wave-transmitting window 22 located on the side wall of the metal housing 1. The wave-transmitting window 22 is covered with a non-metallic wave-transmitting sheet, forming a local wave-transmitting area on the side wall of the metal housing 1. The edge of the wave-transmitting sheet is sealed by laser welding to prevent moisture from entering and causing the antenna performance to deteriorate, so that the communication antenna 8 can transmit signals outward from here.

[0028] In a preferred embodiment of this application, reference is made to Figure 2 One side of the circuit board 3 is soldered with an M.2 interface 31, and the storage module 4 is plugged into the M.2 interface 31; the other side of the circuit board 3 is fitted with a T-nut 32, which is embedded in the positioning hole of the circuit board 3 and fixed by SMT process (surface mount technology). When the M.2 screw 33 is screwed into the T-nut 32, it generates a vertically downward concentrated compressive stress, which offsets the insertion and removal shear force of the interface and prevents the storage module 4 from having poor contact in a vibration environment.

[0029] The application process and implementation principle of this application embodiment are as follows: When a user moves with the portable hard drive, the built-in locator chip 6 continuously generates a position signal and radiates it outward through the wave-transparent part. If the hard drive is accidentally lost, the user sends a positioning command through the mobile terminal, which wakes up the positioning chip via the data interface 5 and broadcasts real-time position data. During this process, the curved structure of the wave-transparent convex hull 211 eliminates the directional obstruction of the signal by the metal shell 1, improving the radiation coverage range, while the low-power mode and the built-in battery 7 maintain ultra-long standby to ensure continuous tracking. During normal use, the vertical compressive stress design of the T-nut 32 effectively suppresses the displacement of the storage module 4 caused by vibration, and the atomized sandblasted surface significantly improves the grip stability, integrating the anti-loss function with the reliability of the device.

[0030] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
