Description

Technical Field

[0001] This utility model relates to the field of solid-state drive structure, and in particular to a solid-state drive component with data security function. Background Technology

[0002] In the current field of data security storage, mechanical hard drive protection devices generally suffer from the technical bottleneck of difficulty in coordinating active protection and covert defense. Traditional solutions mostly rely on a single physical isolation mechanism, lacking effective camouflage strategies when blocking unauthorized access. This allows attackers to easily identify the presence of the real hard drive through interface probing, resulting in the accidental exposure of the real data interface. These limitations make it difficult for existing technologies to balance the reliability of data isolation with the effectiveness of deceptive defense, thus hindering the practical development of high-security storage devices. Utility Model Content

[0003] To address the shortcomings mentioned above in the background technology, this utility model provides a solid-state drive component with data security functions.

[0004] The present invention adopts the following technical solution:

[0005] A solid-state drive component with data security features includes:

[0006] The housing has a data interface located in the middle of one end face.

[0007] A frame is fixed inside the housing, and the frame is provided with guide grooves mirror images of the two sides of the housing. The end of the guide groove near the data interface is bent toward the middle of the housing to form an extension groove.

[0008] A moving mechanism includes a moving component, a fixing component, and a guide wheel. The moving component is mirror-arranged on both sides of the housing. Both moving components are restricted to moving linearly relative to the data interface. The fixing component is provided on each moving component, and the fixing component is restricted to moving linearly relative to both sides of the frame. The guide wheel is provided on one side of the fixing component and is fitted into the guide groove. The two fixing components fix the dummy hard drive and the real hard drive on the other side opposite to the guide wheel, respectively.

[0009] When one of the fixing components moves toward the data interface, its guide wheel moves along the guide groove to the extension groove; the other moving component moves away from the data interface, and its guide wheel moves along the extension groove to the guide groove; thereby driving the fixing component to move the puppet hard drive or the real hard drive to the data interface position, while the other fixing component moves in the opposite direction, causing the corresponding hard drive to retract into the housing.

[0010] In one possible implementation, the moving mechanism further includes a drive wheel and a drive belt. The two ends of the side of the frame facing away from the moving member are provided with the drive wheel, and the two drive wheels are connected to the drive belt. Both moving members are fixed with clamps, and the clamps of the two moving members are respectively fixed to both sides of the drive belt and to both ends of the drive belt.

[0011] In one possible implementation, the moving mechanism further includes a drive motor that drives one of the transmissions to rotate.

[0012] In one possible implementation, first slide rails are fixed on both sides of the frame, each of the first slide rails is adapted to connect to a first slider, and the two moving parts are respectively fixed to the two first sliders.

[0013] In one possible implementation, a second slide rail is fixed to the moving member, the second slide rail is adapted to connect to a second slider, and the fixing member is fixed to the second slider.

[0014] In one possible implementation, the housing includes an upper shell and a lower shell, with a corner threaded post inside the lower shell, and a screw helically connected to the threaded post. A connecting post is provided at the corner inside the upper shell, and each connecting post and each threaded post corresponds one-to-one. The screw passes through the connecting post and the threaded post and is helically connected to the fastener.

[0015] In one possible implementation, the frame is provided with connecting holes at its corners, the frame is disposed inside the lower shell, each connecting hole corresponds to each threaded post, and each connecting post is pressed against the frame, and the screw passes through the connecting post, the connecting hole, and the threaded post to be helically connected and fastened.

[0016] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: This utility model uses two fixing members that move alternately, combined with a guiding mechanism where guide wheels are embedded in and extend from guide grooves. This allows the fixing member that secures the real hard drive to move along the guide groove trajectory towards the data interface, while the other fixing member retracts in the opposite direction to hide the dummy hard drive. If no verification or external connector is inserted, the dummy hard drive remains in the data interface position, and the real hard drive is completely hidden. This design achieves physical isolation between the two hard drives through mechanical linkage, preventing the exposure of real data during unauthorized access and using the dummy hard drive to confuse external attacks, thus possessing both active protection and covert defense advantages.

[0027] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0028] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.

[0029] This utility model provides a solid-state drive component with data security functions, as shown in the attached figure. Figure 1 and 2 As shown, the solid-state drive assembly includes a housing 1, a frame 2, and a moving mechanism. A data interface 101 is located in the middle of one end face of the housing 1. The frame 2 and the moving mechanism are both housed within the housing 1, with the moving mechanism mounted on the frame 2.

[0030] Please refer to the appendix. Figure 3The housing 1 includes an upper housing 11 and a lower housing 12. Threaded posts 13 are provided at the corners of the lower housing 12, and each threaded post 13 is screwed to a screw 15. A data interface 101 is located on the end face of the upper housing 11. Connecting posts 14 are provided at the corners of the upper housing 11, with each connecting post 14 corresponding to one of the threaded posts 13. The screws 15 pass through the connecting posts 14 and the threaded posts 13 and are screwed to secure the upper housing 11 and the lower housing 12, thus forming a complete housing 1 structure. Preferably, the screws 15 are one-way tamper-proof screws.

[0031] Please refer to the appendix. Figure 4 The frame 2 has connecting holes 201 at its corners. The frame 2 is set inside the lower shell 12. When installing the frame 2, the connecting holes 201 of the frame 2 are aligned with the threaded posts 13 respectively. Then, the upper shell 11 is placed on the lower shell 12, so that the connecting posts 14 are pressed against the frame 2. Then, at the position of each connecting post 14, the screws 15 are passed through the connecting post 14, the connecting hole 201 and the threaded post 13 in sequence and screwed together to tighten them. This can fix the upper shell 11 and the lower shell 12, and at the same time, make the connecting posts 14 press the frame 2 against the threaded posts 13, thus fixing the connecting posts 14.

[0032] As attached Figure 4 and 6 As shown, the frame 2 is provided with guide grooves 202 mirror images of the two sides of the housing 1. The end of the guide groove 202 near the data interface 101 is bent toward the middle of the housing 1 to form an extension groove 203. The frame 2 is also provided with a strip-shaped clearance groove 204 on the side of the guide groove 202 near the middle of the housing 1.

[0033] As attached Figure 8 and 9 As shown, the moving mechanism includes a moving component 31, a fixed component 32, and a guide wheel 33. See also the attached diagram. Figures 4 to 6 The housing 1 contains two mirror-image movable members 31. Both movable members 31 are restricted to linear movement relative to the data interface 101. The restriction structure is as follows: both sides of the frame 2 are fixed with first slide rails 311, and both first slide rails 311 are adapted to connect with first sliders 312. The two movable members 31 are respectively fixed to the two first sliders 312. Each movable member 31 is provided with a fixing member 32, and the fixing member 32 is restricted to linear movement relative to both sides of the frame 2. The restriction structure is also achieved through a slide rail and slider structure. Specifically, a second slide rail 321 is fixed to the movable member 31, and the second slide rail 321 is adapted to connect with a second slider 322. The fixing member 32 is fixed to the second slider 322, thereby allowing the movable member 31 to slide linearly along the second slide rail 321 relative to both sides of the housing 1.

[0034] As attached Figure 5 , 7As shown in Figure 8, a guide wheel 33 is also provided on the side of the fixing member 32 near the outside of the housing 1. The guide wheel 33 is fitted into the guide groove 202. When the moving member 31 moves towards the data interface 101, it drives the fixing member 32 to move accordingly. As the guide wheel 33 of the fixing member 32 moves along the guide groove 202 to the extension groove 203, the fixing member 32 moves towards the middle of the housing 1 to the position corresponding to the data interface 101. When the moving member 31 moves away from the data interface 101, it drives the fixing member 32 to move accordingly. As the guide wheel 33 of the fixing member 32 moves along the extension groove 203 to the guide groove 202, the fixing member 32 moves towards the side of the housing 1 and moves to a position inside the housing 1 away from the data interface 101.

[0035] Two fixing members 32 are respectively fixed to the puppet hard disk 5 and the real hard disk 4 on the other side of the guide wheel 33 (i.e., the side closer to the middle of the housing 1). The puppet hard disk 5 is a virtual hard disk without content, and the real hard disk 4 is a virtual hard disk storing real data. When one fixing member 32 moves toward the data interface 101, its guide wheel 33 moves along the guide groove 202 to the extension groove 203. At the same time, the other fixing member 32 moves away from the data interface 101, so that the two fixing members 32 move alternately to the bottom of the data interface 101. This drives the fixing member 32 to move the puppet hard disk 5 or the real hard disk 4 to the position of the data interface 101. At the same time, the other fixing member 32 moves in the opposite direction, so that the corresponding hard disk retracts into the housing 1.

[0036] Continue to refer to the appendix Figure 4 and 6 The moving mechanism also includes transmission wheels 34, transmission belts 35, and drive motors 36. Transmission wheels 34 are provided at both ends of the side of the frame 2 facing away from the moving parts 31. Specifically, bearing seats are fixed to the frame, and the rotating shaft fixed at one end of the transmission wheel 34 is embedded and fixed into the bearing of the bearing seat. The drive motor 36 is fixed to the frame 2 and drives one of the transmission wheels to rotate. The two transmission wheels 34 are connected to the transmission belt 35, where the transmission wheels 34 can be synchronous pulleys, and the transmission belt 35 can be a synchronous belt. The meshing of the synchronous belt and the synchronous pulleys enables one synchronous pulley to rotate, thereby driving the other synchronous pulley to rotate, thus realizing the operation of the synchronous belt. Clamping plates 37 are fixed to both sides of the transmission belt 35, and to both ends of the transmission belt 35. This connection structure allows the transmission belt 35 to move in the direction away from the data interface 101 while one side of the transmission belt 35 is running towards the data interface 101. This enables the other fixed member 32 to move away from the data interface 101 when one fixed member 32 moves towards the data interface 101.

[0037] In addition, a fingerprint recognition device can be installed inside the housing 1. The fingerprint recognition module is disposed on the surface of the housing 1. The drive motor 36 is electrically connected to the fingerprint recognition module. When the user verifies the fingerprint accurately through the fingerprint recognition module, the drive motor 36 starts (e.g., rotates forward a specified number of times), causing the transmission belt 35 to rotate and move the fixing member 32 that fixes the real hard disk 4 towards the data interface 101, thereby moving the real hard disk 4 to the data interface 101. When the fingerprint cannot be correctly recognized, the drive motor 36 cannot start, and the real hard disk 4 will not move to the data interface 101, thus achieving the purpose of protecting the hard disk data security.

[0038] Additionally, a photoelectric sensor, a control module, and a battery can be configured inside the housing 1. The photoelectric sensor is located at the data interface 101. When an external data connector is inserted into the data interface 101, the photoelectric sensor is triggered. The triggered signal is sent to the control system, which then controls the drive motor 36 to start (e.g., rotate a specified number of times), driving the transmission belt 35 to move the fixing piece 32, which holds the dummy hard drive 5, to the data interface 101. In other words, the real hard drive 4 can only move to the data interface 101 after successful fingerprint recognition verification. Under normal conditions, the dummy hard drive 5 is located at the data interface 101, thus misleading anyone other than the user.

[0039] In summary, the two fixing members 32 of the moving mechanism of this utility model respectively fix the real hard drive 4 and the puppet hard drive 5. Through the linkage of the transmission belt 35 and the dual guiding mechanism of the guide wheel 33 embedded in the guide groove 202 and the extension groove 203, the two fixing members 32 are driven to move alternately. When the fingerprint recognition verification is successful, the drive motor 36 drives the transmission belt 35 to rotate, so that the fixing member 32 fixing the real hard drive 4 moves along the trajectory of the guide groove 202 towards the data interface 101, while the other fixing member 32 retracts in the opposite direction to hide the puppet hard drive 5. If the verification is not successful or an external connector is inserted, the puppet hard drive 5 is always in the position of the data interface 101, and the real hard drive 4 is completely hidden. This design achieves physical isolation between the two hard drives through mechanical linkage, which not only prevents the exposure of real data when unauthorized access is made, but also uses the puppet hard drive 5 to confuse external attacks, thus having the dual advantages of active protection and covert defense.

[0040] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
