Description

Technical Field

[0001] This utility model relates to the field of hard disk technology, and in particular to a portable solid-state drive with a retractable plug. Background Technology

[0002] Portable solid-state drives (SSDs) are storage devices that combine the ultra-fast read and write speeds of SSDs with portability. They are made of solid-state electronic storage chip arrays and consist of a main controller, storage units, and bridge chips. They are typically used in high-performance computing and consumer-grade storage. Portable SSDs are relatively compact in size and feature high speed and low power consumption.

[0003] A search of existing Chinese patent technology reveals a device called "A Portable Solid State Drive" (publication number CN222214711U). This device, with its data cable secured inside the hard drive's insertion port, is not easily loosened or detached by external forces. This stability ensures uninterrupted data transmission, improving data transfer stability and reliability. However, due to the typical usage conditions of solid state drives—connection is generally maintained during data transfer for storing important data, and disconnection occurs after data transfer is complete—the connection port is exposed for a period of time. This exposure can lead to contamination of the connector with external debris, making cleaning difficult and potentially affecting the export of important data. Utility Model Content

[0004] Therefore, it is necessary to address the issue that after data transmission is completed, the connection will be disconnected, leaving the solid-state drive's connection port exposed for a period of time. This can lead to the plug becoming contaminated with external impurities, making cleaning difficult and affecting the export of important data. The solution provides a portable solid-state drive with a retractable plug, comprising: two protective shells combined to form a housing; a protective rubber cap at one end of each protective shell, with a rubber strip fixedly connected to the inner wall of the cap, extending into the interior of the housing; and a retraction mechanism installed inside the protective shells, its surface extending to the outer side of the shells. The retraction mechanism includes a data storage block installed on the bottom inner wall of the lower protective shell, with a retraction component connected to its surface, extending into the outer side of the protective shells. Limiting components are provided at both the upper and lower ends of the retraction component, installed on the inner walls of adjacent protective shells.

[0005] In one embodiment, the shrinking assembly includes a connector slidably connected between two protective housings. The connector is disposed inside the protective housing, with one end of the connector away from the data storage block extending to the outside of the protective housing. A connector base is fixedly connected to one end of the connector near the data storage block, and a flexible circuit board is connected to one end of the connector base away from the connector. The other end of the flexible circuit board is connected to the surface of the data storage block.

[0006] In one embodiment, the limiting component includes two positioning blocks fixedly connected to the inner walls of adjacent protective housings. A fixing block is fixedly connected to the surface of the positioning block, and a moving rod is slidably connected to the inner wall of the fixing block. A buckle is fixedly connected to the end of the moving rod near the retraction component, and a spring is sleeved on the surface of the moving rod.

[0007] In one embodiment, two protrusions are fixedly connected to the surface of the connector located on the outside of the protective housing, with the two protrusions respectively fixedly connected to both sides of the connector. The two protrusions are manually clamped, and then pulled to move the connector outwards synchronously.

[0008] In one embodiment, the shrinking assembly further includes a guide frame fixedly connected to the upper end of the data storage block, the guide frame being sleeved on the outside of the flexible circuit board. The guide frame can provide auxiliary guidance for the flexible circuit board, ensuring smooth movement of the flexible circuit board.

[0009] In one embodiment, the surface of the connector has an annular groove, and the end of the connector away from the data storage block abuts against the inner wall of the protective housing. The annular groove, in conjunction with the limiting component, forms an auxiliary positioning.

[0010] In one embodiment, a rubber button is fixedly connected to the end of the movable rod away from the latch block, and the rubber button is embedded in the surface of the adjacent protective housing. The rubber button is made of rubber to maintain the airtightness of the interior of the protective housing.

[0011] In one embodiment, one end of the spring is fixedly connected to the inner wall of the adjacent fixing block, and the other end of the spring abuts against the inner wall of the adjacent rubber button. The spring serves to reset the rubber button.

[0012] Beneficial effects

[0013] The aforementioned retractable plug portable solid-state drive, through the cooperation of the designed retraction component and the protective rubber cap, can provide protection for the connector. The guide bracket can assist in guiding the flexible circuit board, ensuring smooth movement of the flexible circuit board. At the same time, the connector can assist in positioning the connector by moving it outward, making it easy to move the connector outward for easy access during use. After use, the protective rubber cap can be fastened to the end of the protective shell to protect the connector, thus protecting the connection port, improving the convenience of cleaning the connector, and reducing the impact on the export of important data.

[0014] The limiting component can work in conjunction with the retraction component to limit movement. By pressing the rubber button, the rubber button is moved to the snap block and locked into the annular groove, making the connection between the connector and the external connecting wire more stable and secure.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The following is combined with Figures 1-5 This invention describes a portable solid-state drive with a retractable plug.

[0025] In one embodiment, a retractable plug portable solid-state drive includes: two protective shells 1, which are combined to form a housing; a protective rubber cap 2 is provided at one end of the protective shell 1; a rubber strip 21 is fixedly connected to the inner wall of the protective rubber cap 2, and the rubber strip 21 extends through the interior of the housing; and a retraction mechanism 3, which is installed inside the protective shell 1 and extends through the outer side of the protective shell 1; wherein the retraction mechanism 3 includes a data storage block 33 installed on the inner bottom wall of the lower protective shell 1; a retraction component 31 is connected to the surface of the data storage block 33; the surface of the retraction component 31 extends through the outer side of the protective shell 1; and limit components 32 are provided at both the upper and lower ends of the retraction component 31, with the limit components 32 installed on the inner walls of adjacent protective shells 1.

[0026] It should be noted that: Data storage block 33 is the core component inside the solid-state drive (SSD) used for data storage, which is the NAND flash memory chip; the core storage medium, the NAND flash memory chip, retains data through charge capture technology and is composed of non-volatile memory cells, which can retain data for a long time after power failure; its cost usually accounts for more than 70% of the total cost of the SSD; modern SSDs mainly adopt 3D NAND structure, which increases capacity density by vertically stacking memory cells, replacing the earlier planar 2D design; according to the difference in charge state of the memory cells, they can be divided into SLC, MLC, TLC, etc., which directly affect lifespan and performance; controller: manages data read and write, wear leveling, error correction and other operations, and coordinates the work of flash memory chips; DRAM cache models: accelerate the mapping table access and improve random read and write performance; some DRAM-Less models are replaced by HMB technology;

[0027] like Figure 2 , Figure 3 and Figure 4As shown, the shrinking assembly 31 includes a connector 311 slidably connected between two protective shells 1. The connector 311 is disposed inside the protective shell 1. The end of the connector 311 away from the data storage block 33 extends to the outside of the protective shell 1. The end of the connector 311 near the data storage block 33 is fixedly connected to a connector seat 313. Two protrusions 312 are fixedly connected to the surface of the connector 311 on the outside of the protective shell 1. The two protrusions 312 are fixedly connected to both sides of the connector 311. The end of the connector seat 313 away from the connector 311 is connected to a flexible circuit board 314. The other end of the flexible circuit board 314 is connected to the surface of the data storage block 33. An annular groove 316 is formed on the surface of the connector seat 313. The end of the connector seat 313 away from the data storage block 33 abuts against the inner wall of the protective shell 1. The shrinking assembly 31 also includes a guide frame 315 fixedly connected to the upper end of the data storage block 33. The guide frame 315 is sleeved on the outside of the flexible circuit board 314.

[0028] In this embodiment, when needed, the two protrusions 312 can be manually clamped and pulled to move the connector 311 outward synchronously, so that the connector 313 will fit against the inner wall of the protective shell 1, allowing the connector 311 to be exposed to the outside of the protective shell 1 for easy insertion and use. At the same time, the guide frame 315 can form an auxiliary guide device for the flexible circuit board 314, keeping the flexible circuit board 314 moving smoothly. Meanwhile, the connector 313 can form an auxiliary positioning function when the connector 311 is moved outward, and the protrusions 312 can restrict the bend of the connector 311 from retracting into the interior of the protective shell 1. At the same time, it is convenient to move the connector 311 outward for easy access when using. After use, the protective cap 2 can be fastened to the end of the protective shell 1 to protect the shrinking component 31.

[0029] like Figure 2 , Figure 3 and Figure 5 As shown, the limiting component 32 includes two positioning blocks 321 fixedly connected to the inner wall of the adjacent protective shell 1. A fixing block 322 is fixedly connected to the surface of the positioning block 321. A moving rod 323 is slidably connected to the inner wall of the fixing block 322. A buckle 324 is fixedly connected to the end of the moving rod 323 near the retraction component 31. A spring 326 is sleeved on the surface of the moving rod 323. A rubber button 325 is fixedly connected to the end of the moving rod 323 away from the buckle 324. The rubber button 325 is embedded in the surface of the adjacent protective shell 1. One end of the spring 326 is fixedly connected to the inner wall of the adjacent fixing block 322, and the other end of the spring 326 abuts against the inner wall of the adjacent rubber button 325.

[0030] In this embodiment, the limiting component 32 can press the rubber button 325 so that the rubber button 325 abuts against the buckle 324 and is engaged in the annular groove 316 via the moving rod 323. This makes the connector 311 more stable and secure when it is plugged into the external connecting wire. After use, the spring 326 will abut against the rubber button 325 to reset it. At the same time, the reset of the rubber button 325 will cause the buckle 324 to separate from the annular groove 316, so that the retraction component 31 can reset and retract into the interior of the protective shell 1.

[0031] Working principle: Manually clamp the two protrusions 312 and pull to move the connector 311 outward synchronously. The connector 313 fits against the inner wall of the protective shell 1, and the connector 311 is exposed to the outside of the protective shell 1 for easy insertion. The guide frame 315 assists in guiding the flexible circuit board 314 to keep the flexible circuit board 314 moving smoothly. The connector 313 assists in positioning the connector 311 as it moves outward. The limiting component 32 presses the rubber button 325 and abuts against the buckle 324 through the moving rod 323 to engage with the ring groove 316. After use, the spring 326 abuts against the rubber button 325 to reset. The reset of the rubber button 325 causes the buckle 324 to separate from the ring groove 316. The retraction component 31 resets and retracts into the interior of the protective shell 1. The protrusions 312 restrict the retraction of the bend of the connector 311 into the interior of the protective shell 1, and the protective rubber cover 2 is fastened to the end of the protective shell 1.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
