Abstract
Description
Technical Field
[0001] The utility model relates to the field of electronic data storage devices, in particular to a waterproof and dustproof solid-state hard disk. Background Art
[0002] A solid-state drive (SSD) stores data using solid-state memory chips. Compared to traditional mechanical hard drives, SSDs lack mechanical components, resulting in faster data access speeds, lower power consumption, quieter operation, and greater durability. SSDs utilize flash memory technology, typically NAND flash chips, to store data. Without rotating disks and read / write heads, SSDs offer faster data read and write speeds, faster boot times, and more responsive applications. SSDs are also more durable and more resilient to vibration and temperature fluctuations. In recent years, SSDs have become the storage of choice for many PCs, laptops, servers, and data centers.
[0003] A SATA solid-state drive (SSD) uses a Serial ATA interface. It stores data using solid-state memory, offering faster read and write speeds, lower power consumption, and higher reliability than traditional mechanical hard drives. SATA SSDs are compact and lightweight, making them suitable for a variety of devices, including laptops and desktops. They typically offer large capacities, meeting user storage needs for work, entertainment, and everyday use.
[0004] Solid-state drives usually have circuit boards. During use, the electronic components generate electrostatic adsorption effects on dust in the air, causing the solid-state drive to become dirty and significantly reducing its service life. Excessive electronic components on the circuit board that come into contact with water will directly connect the circuits, causing the circuit board to short-circuit and the electronic components to burn out.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0030] See also Figure 1-6 , the utility model provides a technical solution:
[0031] A waterproof and dustproof solid-state drive includes a housing 1, a connector 3 provided on one side of the housing 1, a housing 2 sealed to the housing 1, and a circuit board 4 mounted within the housing 1. The circuit board 4 is provided with various electronic components for implementing storage functions. The sealed connection between the housing 1 and the housing 2 prevents water from intruding and damaging the internal devices.
[0032] Furthermore, a joint hole 5 is formed on the side of the housing 1, and a first sealing groove 23 is formed in the joint hole 5. A first mounting groove 6 is formed on the inner bottom surface of the housing 1. Four sets of internally threaded studs 7 are welded to the four corners of the first mounting groove 6. Four sets of internally threaded studs 2 are welded to the four corners of the housing 1. A sealing protrusion 9 is provided on the housing 1. A sealing ring can be placed outside the sealing protrusion 9 to enhance airtightness.
[0033] Furthermore, a connector 3 is mounted in the housing 1 at a location corresponding to the connector hole 5, and a circuit board 4 is mounted in the housing 1 at a location corresponding to the first mounting slot 6. The connector 3 and the circuit board 4 are electrically connected via a flat cable 10. The connector hole 5 and the connector 3 are sealed, and the connector 3 is replaceable.
[0034] Furthermore, connector 3 is provided with a second mounting groove 21, into which a resilient sealing ring 22 is adhered. Sealing ring 22 engages in first sealing groove 23, sealingly connecting connector 3 to connector hole 5. Connector 3 is provided with a power connector 15 and a data connector 16. Power connector 15 is a SATA power interface that complies with current national standards, and data connector 16 is a SATA data interface that complies with current national standards. The use of resilient sealing ring 22, which elastically squeezes connector 3 to connector hole 5, eliminates the need for welding and other methods, making connector replacement more convenient.
[0035] Furthermore, circuit board 4 is provided with a main control chip 11, cache particles 12, and multiple groups of flash memory particles 13. Main control chip 11 is electrically connected to cache particles 12, which in turn are electrically connected to multiple groups of flash memory particles 13. Circuit board 4 is provided with mounting holes 14 corresponding to internally threaded studs 7, and circuit board 4 is fixed to internally threaded studs 7 via screws. Cache particles 12 are used for quick, temporary storage. When the device loses power, all data in cache particles 12 is cleared. The data in cache particles 12 is then controlled by main control chip 11 to be stored in flash memory particles 13. Flash memory particles 13 are used for long-term storage, and data is retained even after the device loses power.
[0036] Furthermore, a second sealing groove 17 is defined in the second housing 2, into which a sealing gasket 19 is installed. A groove 20 is defined in the sealing gasket 19, which corresponds to the sealing protrusion 9. The sealing protrusion 9 is inserted into the groove 20. A fixing hole 18 is defined in the second housing 2, corresponding to the second internally threaded post 8. The second housing 2 is fixedly connected to the first housing 1 via screws. The fixing hole 18 should be filled with sealant to prevent liquid from entering the interior through the fixing hole 18.
[0037] Working Principle: To use this device, connect the data and power cables to data connector 16 and power connector 15. Main control chip 11 controls data storage. Since cache memory chips 12, which are typically LPDDR4 cache memory chips, are faster than flash memory chips 13, data is first stored in cache memory chips 12, which then transfers it to flash memory chips 13. Data readback is also controlled by main control chip 11, which reads data from flash memory chips 13 and caches it in computer memory. Housing 1 1 and housing 2 2 are sealed together.
[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
