Description

Technical Field

[0001] This invention relates to the field of portable hard drive technology, specifically a portable data storage hard drive. Background Technology

[0002] Portable hard drives can store photos, documents, videos, and other data to meet users' daily work needs. Portable hard drives usually have an interface. If the interface or casing is broken, water may enter and damage the internal circuitry or disk. To solve this problem, a waterproof structure is added to the portable hard drive to improve its waterproof performance.

[0003] As disclosed in existing technical solutions, CN218939250U discloses a waterproof portable hard drive; relating to the field of portable storage, it specifically includes a protective shell, inside which is a protective inner shell. The upper and bottom surfaces of the inner shell are fixedly connected to equidistantly arranged reinforcing springs, the top of each reinforcing spring being fixedly connected to the inner wall of the protective shell. The outer and bottom surfaces of the inner shell are fixedly connected to equidistantly arranged buffer dampers. This device, through the coordinated use of the protective inner shell, reinforcing springs, buffer dampers, buffer plates, and protective pads, allows the protective shell to compress the reinforcing springs and protective pads when subjected to external pressure, enabling the reinforcing springs and protective pads to buffer and dissipate force, preventing external pressure from being transmitted to the waterproof hard drive body. This protects the waterproof hard drive body from impacts and solves the problem of damage to the waterproof hard drive body from impacts.

[0004] Some devices protect the external hard drive by adding a waterproof protective cover. For example, CN113948111A discloses a device to prevent water ingress into the interface of an external hard drive. A protective layer is slidably connected to the middle of the side of the external hard drive. A spring is fixedly connected to the upper side of the protective layer, and a shock-absorbing housing is fixedly connected to the other side of the spring. A second spring is fixedly connected to the lower side of the protective layer, and a second shock-absorbing housing is fixedly connected to the other side of the spring. A limit rod is fixedly connected to the second shock-absorbing housing through a spring in a spring groove. A fixed base is fixedly connected to the middle of the bottom of the inner side of the protective layer, and a slide is fixedly connected to the upper end of the fixed base. Pressing down on the external hard drive moves it toward the fixed base. The downward movement of the external hard drive causes the pull plate to descend. Pulling the vertical rod downward causes the swing arm to rotate, moving the movable cover toward the external hard drive. The interface plug at the bottom of the movable cover inserts into the USB interface at the top of the external hard drive, blocking the USB interface. The device then enters a closed state, achieving the purpose of preventing water from entering the USB interface.

[0005] However, the aforementioned waterproof structures require the user to manually plug the USB port of the portable hard drive after use, or manually put the portable hard drive into the protective case. If the user forgets to perform this step, the waterproof structure will still be ineffective for the portable hard drive. Therefore, it is particularly important to achieve automatic waterproofing of the portable hard drive after use. To this end, we propose a portable data storage hard drive. Summary of the Invention

[0012] Preferably, the metal inner shell slides on the waterproof upper shell by activating a sliding button and a sliding button movable groove, and the metal inner shell slides on the waterproof lower shell by a hard drive extension guide groove and a hard drive extension guide block.

[0013] Preferably, the waterproof plug assembly includes a waterproof plate slidably connected to the front end of the waterproof lower housing, and a rubber pad slidably connected inside the waterproof plate. A positioning telescopic rod is installed between the rubber pad and the waterproof plate, and a guide return spring is sleeved on the surface of the positioning telescopic rod. An electromagnet positioning component is fixed to the inner wall of the waterproof plate, and a metal part is provided on one side of the electromagnet positioning component and adhered to the rubber pad.

[0014] Preferably, the rubber pad has an arc-shaped groove at one end near the vertical center line of the mobile hard drive assembly, and a transmission rope connector is provided at the connection between the hard drive rebound transmission assembly and the waterproof plate.

[0015] Preferably, the hard disk spring-loaded transmission assembly is fixedly connected to the side of the waterproof plate away from the vertical center line of the mobile hard disk assembly, and the waterproof plate slides on the waterproof lower housing through the hard disk spring-loaded transmission assembly.

[0016] Preferably, the hard drive spring-loaded transmission assembly includes a spring-loaded transmission rope installed inside the mobile hard drive assembly. The surface of the spring-loaded transmission rope is provided with a sliding wheel one fixed to the front side inside the waterproof lower housing and a sliding wheel two fixed to the rear side inside the waterproof lower housing. One end of the spring-loaded transmission rope is fixedly connected to the waterproof plate, and the other end of the spring-loaded transmission rope is fixedly connected to a spring-loaded transmission plate. The spring-loaded transmission plate is integrally fixed to the metal inner shell.

[0017] Preferably, the hard disk spring-loaded transmission assembly is further provided with a guide bracket mounted on the spring-loaded transmission plate.

[0020] As can be seen from the above description, the technical solution described in this application can certainly solve the technical problem that this application aims to address.

[0021] Meanwhile, through the above technical solutions, the present invention has at least the following beneficial effects:

[0022] This invention incorporates an automatic retraction mechanism within the portable hard drive assembly. During use, the internal USB interface is exposed after the metal inner shell is extended, allowing data connection to a computer via a data cable. Releasing the finger activates the assembly, simultaneously retracting the entire metal inner shell into the waterproof upper shell. This also activates a rubber pad in the waterproof plug assembly that matches the data cable, providing comprehensive waterproof protection and preventing data loss due to water damage to the hard drive's interface. Throughout the mechanism's operation, no manual intervention is required to automatically open and close the interface; it opens to expose the interface upon insertion and immediately closes after insertion.

[0023] The activation component and the waterproof plug component of this invention are interconnected. During use, the activation component can control whether the electromagnet positioning component is energized through a microcontroller connected to a micro pressure sensor, so as to meet the bidirectional switching operation of the waterproof plate and the rubber pad. When the electromagnet positioning component is energized, the waterproof plates close together and close the interface. When the electromagnet positioning component is de-energized, the rubber pads close together and clamp the cable body inserted into the data cable, thereby preventing water from entering the interior of the mobile hard drive component through the cable. At the same time, the activation component is also the power source of the entire hard drive rebound transmission component. Only when the activation sliding button is slid, the metal inner shell can be driven to slide in the waterproof lower shell. After releasing the activation sliding button, the metal inner shell can be automatically reset and the entire metal inner shell can be retracted into the waterproof lower shell, realizing the automatic rebound protection effect of the mobile hard drive interface.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Implementation Case 1

[0034] As attached Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the present invention provides a technical solution: a mobile data storage hard disk, including a mobile hard disk assembly 1 and a mobile hard disk automatic retraction mechanism located on the mobile hard disk assembly 1;

[0035] The surface of the top and bottom of the portable hard drive assembly 1 is provided with several equally spaced and evenly distributed heat dissipation holes 6, and an indicator light body 2 is installed on one side of the top of the portable hard drive assembly 1.

[0036] The portable hard drive assembly 1 includes a waterproof upper shell 101 and a waterproof lower shell 103. A metal inner shell 102 is installed inside the waterproof upper shell 101 and the waterproof lower shell 103. A hard drive extension guide groove 105 is fixed at the connection between the metal inner shell 102 and the waterproof lower shell 103. A hard drive extension guide block 106, which matches the hard drive extension guide groove 105, is fixed on the metal inner shell 102. Several thermally conductive silicon strips 107 are bonded to the surface of the metal inner shell 102. Two sets of heat sinks 108 are bonded to the surface of the waterproof lower shell 103.

[0037] The portable hard drive automatic retraction mechanism includes a hard drive spring-loaded transmission assembly 5 installed between the metal inner shell 102 and the waterproof lower shell 103, an activation assembly 3 located on top of the waterproof upper shell 101, and a waterproof plug assembly 4 installed at the front end of the waterproof lower shell 103. A USB interface 104 matching the position of the waterproof plug assembly 4 is installed at the front end of the metal inner shell 102. When in use, the portable hard drive automatic retraction mechanism pushes out the metal inner shell 102, exposing the internal USB interface 104, and connects to a computer via a data cable. Releasing the activation assembly 3 with a finger causes the entire metal inner shell 102 to retract into the waterproof upper shell 101, activating the rubber pad 402 in the waterproof plug assembly 4 that matches the data cable, achieving comprehensive waterproof protection and preventing data loss due to water damage to the interface. During the entire operation of the mechanism, no other manual operation is required to automatically open and close the interface; that is, the interface is opened when inserted and immediately closed after insertion.

[0038] Example 2

[0039] The solution in Example 1 will be further described below with reference to its specific working method.

[0040] like Figure 1 and Figure 4 As shown, in a preferred embodiment, based on the above method, the activation component 3 further includes an activation sliding button 301 fixed on the metal inner shell 102 and a sliding button movable groove 304 formed on the surface of the waterproof upper shell 101. An activation electrical contact 302 is fixed on the front end surface of the activation sliding button 301, and a miniature pressure sensor 303 corresponding to the position of the activation electrical contact 302 is fixed on the inner wall of the sliding button movable groove 304. The metal inner shell 102 slides on the waterproof upper shell 101 through the activation sliding button 301 and the sliding button movable groove 304. The metal inner shell 102 slides on the waterproof lower shell 103 via the hard drive extension guide groove 105 and the hard drive extension guide block 106. During the assembly of the portable hard drive, the microcontroller controls the activation component 3 and the waterproof plug component 4 in a coordinated manner. When the portable hard drive is needed, the activation sliding button 301 is pushed forward, causing the activation electrical contact 302 to collide with the micro pressure sensor 303. After the micro pressure sensor 303 detects a certain pressure value, it transmits it to the microcontroller, and the activation sliding button 301 synchronously drives the entire metal inner shell 102 to move forward.

[0041] like Figure 3 and Figure 6As shown, in a preferred embodiment, based on the above method, the waterproof plug assembly 4 further includes a waterproof plate 401 slidably connected to the front end of the waterproof lower housing 103, and a rubber pad 402 slidably connected inside the waterproof plate 401. A positioning telescopic rod 406 is installed between the rubber pad 402 and the waterproof plate 401, and a guide return spring 407 is sleeved on the surface of the positioning telescopic rod 406. An electromagnet positioning component 404 is fixed to the inner wall of the waterproof plate 401, and a metal part 403 is provided on one side of the electromagnet positioning component 404 and bonded to the rubber pad 402. An arc-shaped groove is opened on the end of the rubber pad 402 near the vertical center line of the mobile hard disk assembly 1. A transmission rope connector 405 is provided at the connection between the hard disk spring transmission assembly 5 and the waterproof plate 401. The hard disk spring-loaded transmission assembly 5 is fixedly connected to the side of the waterproof plate 401 away from the vertical center line of the mobile hard disk assembly 1. The waterproof plate 401 slides on the waterproof lower housing 103 through the hard disk spring-loaded transmission assembly 5. The rubber pad 402 is elastically connected to the waterproof plate 401 through the positioning telescopic rod 406 and the guide return spring 407. After the data cable is connected, the microcontroller controls the electromagnet positioning component 404 to be de-energized. Under the elastic action of the positioning telescopic rod 406 and the guide return spring 407, the rubber pad 402 is driven to slide outward. The return spring 508 retracts inward and drives the entire spring-loaded transmission rope 502 to return to its original position. At this time, the interface between the USB interface 104 and the data cable is retracted into the mobile hard disk assembly 1 under the action of the metal inner housing 102, while the rubber pad 402 is stuck on the cable to prevent water from entering.

[0042] like Figure 6 and Figure 7As shown, in a preferred embodiment, based on the above method, the hard disk spring-loaded transmission assembly 5 further includes a spring-loaded transmission rope 502 installed inside the mobile hard disk assembly 1. The surface of the spring-loaded transmission rope 502 is provided with a sliding wheel 501 fixed to the front side inside the waterproof lower housing 103 and a sliding wheel 503 fixed to the rear side inside the waterproof lower housing 103. One end of the spring-loaded transmission rope 502 is fixedly connected to the waterproof plate 401, and the other end of the spring-loaded transmission rope 502 is fixedly connected to a spring-loaded transmission plate 504. The spring-loaded transmission plate 504 is integrally fixed to the metal inner housing 102. The hard disk spring-loaded transmission assembly 5 also includes a guide bracket 507 installed on the spring-loaded transmission plate 504. Telescopic connecting rods 505 are provided between the guide bracket 507, the spring-loaded transmission plate 504, and the waterproof lower housing 103, and the two sets of telescopic connecting rods 505 are pin-connected to each other. The telescopic connecting rods 505 are connected to the spring-loaded transmission plate 504 and the waterproof lower housing 103. Each connection point is equipped with a connecting fastener 506. A spring connector 509 is installed between the two sets of telescopic connecting rods 505, and a return spring 508 is installed between the spring connectors 509. The ends of the telescopic connecting rods 505 slide on the guide bracket 507, and the return spring 508 is sleeved on the outside of the guide bracket 507. The two sets of telescopic connecting rods 505 form an inverted V-shaped structure. The rebound transmission plate 504 moves away from the sliding wheel 2 503. At the same time, the included angle between the two sets of telescopic connecting rods 505 increases, and the return spring 508 is pulled outward. The distance between the rebound transmission plate 504 and the connection point away from the sliding wheel 2 503 increases. Since the length of the entire rebound transmission rope 502 remains unchanged, the distance between the waterproof plate 401 and the sliding wheel 1 501 decreases under the pull of the rebound transmission rope 502. At this time, the waterproof plate 401 slides open in the waterproof lower housing 103 until the USB interface 104 is exposed after passing between the two sets of waterproof plates 401.

[0043] In summary:

[0044] This invention addresses the technical problem that some existing portable hard drives require manual plugging of the USB port or manual placement into a protective case after use. If the user forgets to perform this step, the waterproof structure is ineffective. Therefore, achieving automatic waterproofing of portable hard drives after use is crucial. The invention employs the technical solutions described in the above embodiments. Furthermore, the implementation process of the above technical solutions is as follows:

[0045] During the assembly of the portable hard drive, the activation component 3 and the waterproof plug component 4 are controlled by a microcontroller. When the portable hard drive is needed, the activation sliding button 301 is pushed forward, causing the activation contact 302 to collide with the micro pressure sensor 303. The micro pressure sensor 303 detects a certain pressure value and transmits it to the microcontroller. The activation sliding button 301 simultaneously moves the entire metal inner shell 102 forward, causing the spring-loaded transmission plate 504 to move away from the sliding wheel 503. At the same time, the angle between the two sets of telescopic connecting rods 505 increases, pulling the return spring 508 outward. The distance between the spring-loaded transmission plate 504 and the point away from the sliding wheel 503 increases. Since the length of the entire spring-loaded transmission rope 502 remains unchanged, the distance between the waterproof plate 401 and the sliding wheel 501 decreases under the pull of the spring-loaded transmission rope 502. At this time, the waterproof plate 401 slides open on the waterproof lower shell 103 until the USB interface 1 is reached. After passing between two sets of waterproof plates 401, the USB interface 104 is exposed. A data cable is connected to the USB interface 104, and the other end of the data cable is connected to the computer. After the data cable is connected, the microcontroller controls the electromagnet positioning component 404 to de-energize. Under the elastic action of the positioning telescopic rod 406 and the guide return spring 407, the rubber pad 402 slides outward. The return spring 508 retracts inward and drives the entire return transmission rope 502 to return to its original position. At this time, the interface between the USB interface 104 and the data cable is retracted into the mobile hard drive assembly 1 under the action of the metal inner shell 102. The rubber pad 402 is stuck on the cable to prevent water from entering. When it is necessary to unplug the data cable, the sliding button 301 is activated again to expose the USB interface 104. After the data cable on the USB interface 104 is unplugged, the microcontroller controls the electromagnet positioning component 404 to be energized. At this time, the waterproof plate 401 slides inward and closes, completely blocking the USB interface 104 to prevent water from entering the interface.

[0046] With the above-mentioned settings, this application will certainly solve the above-mentioned technical problems, and at the same time achieve the following technical effects:

[0047] This invention incorporates an automatic retraction mechanism inside the portable hard drive assembly 1. During use, the metal inner shell 102 is extended to expose the internal USB interface 104, allowing data connection to a computer via a data cable. Simultaneously, releasing the finger activates the component 3, causing the entire metal inner shell 102 to retract into the waterproof upper shell 101. This also activates the rubber pad 402 in the waterproof plug assembly 4, which matches the data cable, providing comprehensive waterproof protection and preventing data loss due to water damage to the hard drive's interface. Throughout the mechanism's operation, no manual operation is required to automatically open and close the interface; the interface opens upon insertion and immediately closes after insertion.

[0048] The activation component 3 and the waterproof plug component 4 of this invention are linked together. In use, the activation component 3 can control whether the electromagnet positioning component 404 is energized by a microcontroller connected to the micro pressure sensor 303, so as to meet the bidirectional switching operation of the waterproof plate 401 and the rubber pad 402. When the electromagnet positioning component 404 is energized, the waterproof plate 401 closes to each other and closes the interface. When the electromagnet positioning component 404 is de-energized, the rubber pad 402 closes to each other and clamps the cable body of the inserted data cable, thereby preventing water from entering the interior of the mobile hard drive component 1 through the cable. At the same time, the activation component 3 is also the power source of the entire hard drive rebound transmission component 5. Only when the activation sliding button 301 is slid, the metal inner shell 102 can be driven to slide in the waterproof lower shell 103. After releasing the activation sliding button 301, the metal inner shell 102 can be automatically reset and the entire metal inner shell 102 can be put into the waterproof lower shell 103, realizing the automatic rebound protection effect of the mobile hard drive interface.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
