Description

Technical Field

[0001] This utility model relates to the field of smart USB flash drives, specifically to a smart USB flash drive designed to prevent loss. Background Technology

[0002] A smart USB flash drive is a new type of storage device. It is not just a simple storage medium, but also incorporates intelligent technology to provide a more convenient and secure data management experience. A smart USB flash drive, also known as a smartphone USB flash drive or V-disk, looks like a small USB flash drive and is easy to carry. It connects to devices such as computers or smartphones through a USB interface to achieve plug-and-play data access.

[0003] A search revealed a utility model of a smart USB flash drive with anti-loss function, with announcement number CN216598259U. The flash drive includes a body and an insertion end. The insertion end has a side groove, and the body has an inner groove on its end face, with the inner groove communicating with the side groove. This utility model connects a connecting plate to a retaining plate at its outer end, allowing the retaining plate to movably fit into the side groove. A horizontal plate is fixedly connected to the side of the connecting plate, allowing the horizontal plate to movably fit into a sleeve hole on the side of the body. A pressing plate is fixedly connected to the outer end face of the horizontal plate, and a spring is fixedly connected to the side of the connecting plate. During insertion, pressing the pressing plate moves the retaining plate into the side groove via the connecting plate. After insertion, releasing the pressing plate allows the spring's elasticity to cause the connecting plate to tend towards a reset, causing the retaining plate to move outward and press against the inner surface of the USB interface. This compensates for wear, improves the stability of actual insertion, and enhances the stability of data transmission.

[0004] Existing smart USB drives are easily lost unintentionally, and most currently lack anti-loss structures. Since smart USB drives typically store important data, loss could lead to data leaks or unauthorized access, especially when storing sensitive or confidential information. This risk is particularly serious, as data leaks can not only damage personal privacy but also cause significant losses to businesses. While the smart USB drive in the aforementioned comparative case has an anti-loss function, although the patent title is "anti-loss function," its structure does not implement how to prevent loss. Therefore, once lost, the smart USB drive cannot be recovered, and there is also the risk of unauthorized access by others.

[0005] Therefore, it is necessary to invent a smart USB flash drive that is designed to prevent loss in order to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a smart USB flash drive that is designed to prevent loss. It connects to the user's mobile phone via a wireless communication module inside the casing, allowing an internal positioning module to provide the flash drive's location information. This enables the flash drive to be displayed even if lost. During normal use, when the plug is disconnected from the computer, a connection detection module detects whether the plug is disconnected. If the connection is not re-established within a set delay time via a delay circuit module, the smart control module triggers a locking mechanism. This locks the encryption module, shuts down the data read / write interface, and encrypts the stored data to ensure data security. This addresses the problem mentioned in the background art, where existing smart USB flash drives are easily lost unintentionally. Currently, most smart USB flash drives lack anti-loss structures, and since they typically store important data, loss could lead to data leakage or unauthorized access. This risk is particularly serious when storing sensitive or confidential information, as data leakage can not only harm personal privacy but also cause significant losses to businesses.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a smart USB flash drive that is designed to prevent loss, including a protective cover for protecting the smart USB flash drive;

[0008] A housing is located inside a protective cover, and a plug end is provided at one end of the housing.

[0009] A limiting mechanism is located on the rear side of the protective cover for limiting movement;

[0010] A control component is installed inside the housing. The control component includes a circuit board installed inside the housing. The surface of the circuit board is provided with a storage module, an intelligent control module, a connection detection module, a delay circuit module, a positioning module, a locking encryption module, and a wireless communication module.

[0011] Preferably, the upper side of the housing and the inside of the protective cover are each provided with a magnetic attraction, and the housing and the protective cover are rotatably connected.

[0012] Preferably, the limiting mechanism includes a fixing frame, which is fixed to the inner rear side of the protective cover. A telescopic handle is slidably connected to the inside of the fixing frame and the inside of the protective cover. A fixing block is fixedly connected to the upper and lower parts of the telescopic handle. A spring is provided on the rear side of the fixing block and inside the fixing frame.

[0013] Preferably, the housing is provided in two sets, with a locking block fixedly connected to the lower part of the upper housing, and a locking groove opened inside the lower housing, and the two sets of housings are movably locked together.

[0014] Preferably, the input terminal of the connection detection module is connected to the output terminal of the intelligent control module, and the input terminal of the intelligent control module is connected to the output terminals of the delay circuit module and the locking encryption module.

[0015] Preferably, the input terminal of the wireless communication module is connected to the output terminal of the intelligent control module, and the input terminal of the intelligent control module is connected to the output terminal of the positioning module.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. Through the design of the casing and control components, the location of the smart USB flash drive can be effectively located. At the same time, the storage module in the smart USB flash drive is encrypted to prevent unauthorized access. The wireless communication module inside the casing connects to the user's mobile phone, allowing the internal positioning module to provide the location information of the smart USB flash drive. It can display the location of the smart USB flash drive in the event of loss. In daily use, when the plug is disconnected from the computer, the connection detection module detects whether the plug is disconnected from the computer. If the connection is not re-established within the set delay time by the delay circuit module, the smart control module will trigger the locking mechanism. This will lock the encryption module, close the data read / write interface, and encrypt the stored data to ensure data security.

[0018] 2. Through the design of the housing, magnetic attraction, plug end, and limiting mechanism, the plug end can be fixed to the housing when not in use, preventing damage to the plug end from external dust or collisions that would prevent data reading. By rotating the housing and plug end inside the protective cover, and aligning the plug end with the inside of the protective cover, the telescopic handle on the back of the protective cover is pulled, causing both ends of the telescopic handle to extend into the fixing frame. Then, the plug end is positioned between the two sets of fixing frames. After releasing the telescopic handle, the spring rebound pushes the locking block and telescopic handle to extend out of the fixing frame, thereby limiting the plug end on both sides and enhancing protection.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-6 The illustrated anti-loss smart USB flash drive includes a protective cover 1 for protecting the smart USB flash drive;

[0030] The housing 2 is located inside the protective cover 1, and a plug end 4 is provided at one end of the housing 2;

[0031] The limiting mechanism 5 is located on the rear side of the protective cover 1 and is used for limiting movement;

[0032] The control component 8 is installed inside the casing 2. The control component 8 includes a circuit board 801, which is installed inside the casing 2. The surface of the circuit board 801 is provided with a storage module 802, an intelligent control module 803, a connection detection module 804, a delay circuit module 805, a positioning module 806, a locking encryption module 807, and a wireless communication module 808. The wireless communication module 808 inside the casing 2 connects to the user's mobile phone, allowing the internal positioning module 806 to provide the location information of the smart USB flash drive, which can display the location of the smart USB flash drive in the event of loss. In daily use, when the plug end 4 is disconnected from the computer, the connection detection module 804 detects whether the plug end 4 is disconnected from the computer. If the connection is not re-established within the set delay time by the delay circuit module 805, the intelligent control module 803 will trigger the locking mechanism, which will close the data read / write interface and encrypt the stored data through the locking encryption module 807 to ensure data security.

[0033] like Figure 1 and Figure 2 As shown, a magnet 3 is provided on the upper side of the housing 2 and inside the protective cover 1. The housing 2 and the protective cover 1 are rotatably connected. The housing 2 rotates inside the protective cover 1, and the magnet 3 on the upper side of the housing 2 aligns with the magnet 3 inside the protective cover 1 and sticks together to enhance the connection.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the limiting mechanism 5 includes a fixing frame 501, which is fixed to the inner rear side of the protective cover 1. A telescopic handle 502 is slidably connected to the inside of the fixing frame 501 and the inside of the protective cover 1. A fixing block 503 is fixedly connected to the upper and lower parts of the telescopic handle 502. A spring 504 is provided on the rear side of the fixing block 503 and inside the fixing frame 501. By rotating the housing 2 and the plug end 4 inside the protective cover 1, when the plug end 4 is aligned with the inside of the protective cover 1, the telescopic handle 502 on the rear side of the protective cover 1 is pulled, so that both ends of the telescopic handle 502 extend and retract into the fixing frame 501. Then, the plug end 4 is placed between the two sets of fixing frames 501. Then, the telescopic handle 502 is released, and the spring 504 rebounds and pushes the locking block 6 and the telescopic handle 502 to extend and retract from the fixing frame 501, thereby limiting the two sides of the plug end 4 and enhancing the protection.

[0035] like Figure 1 and Figure 4 As shown, the housing 2 is provided with two sets. The lower part of the upper housing 2 is fixedly connected with a locking block 6, and the interior of the lower housing 2 is provided with a locking groove 7. The two sets of housing 2 are movably locked together. The locking block 6 at the bottom of the upper housing 2 is aligned with the locking groove 7 inside the lower housing 2 to form a locking and docking.

[0036] like Figure 5 and Figure 6 As shown, the input terminal of the connection detection module 804 is connected to the output terminal of the intelligent control module 803. The input terminal of the intelligent control module 803 is connected to the output terminals of the delay circuit module 805 and the lock encryption module 807. The connection detection module 804 detects whether the plug terminal 4 is disconnected from the computer. If the connection is not re-established within the set delay time by the delay circuit module 805 after disconnection, the intelligent control module 803 will trigger the locking mechanism, which will close the data read / write interface and encrypt the stored data through the lock encryption module 807 to ensure data security.

[0037] like Figure 5 and Figure 6As shown, the input terminal of the wireless communication module 808 is connected to the output terminal of the intelligent control module 803, and the input terminal of the intelligent control module 803 is connected to the output terminal of the positioning module 806. The wireless communication module 808 inside the casing 2 connects to the user's mobile phone, allowing the internal positioning module 806 to provide the location information of the smart USB flash drive, which can display the location of the smart USB flash drive during the loss process.

[0038] The working principle of this utility is as follows: When the smart USB flash drive needs to be inserted into a computer, the plug 4 at the front of the casing 2 is inserted into the computer's USB port. The connection detection module 804 detects the connection status between the plug 4 and the computer's USB port. After the connection is complete, a password is entered, and then the storage module 802 inside the USB flash drive is accessed to read data. Important data is then stored in the smart USB flash drive. After storage is complete, the plug 4 is unplugged, and the casing 2 and the plug 4 are rotated inside the protective cover 1. After the plug 4 is rotated to align with the inside of the protective cover 1, the telescopic handle 502 on the back of the protective cover 1 is pulled, causing both ends of the telescopic handle 502 to extend into the fixing bracket 501. Then, the plug 4 is positioned between the two sets of fixing brackets 501. Finally, the telescopic handle 502 is released, and the spring 504 rebounds, pushing the locking block 6 and the telescopic handle 502 out of the fixing bracket 501. The connector 1 extends outwards, thus limiting the two sides of the plug end 4 and enhancing protection. Then, the wireless communication module 808 inside the casing 2 connects to the user's mobile phone, allowing the internal positioning module 806 to provide the location information of the smart USB flash drive. This allows the smart USB flash drive to be displayed in the event of loss. When the plug end 4 is disconnected from the computer, the connection detection module 804 detects whether the plug end 4 is disconnected from the computer. When disconnected, the intelligent control module 803 sends the detected data to the delay circuit module 805. If the delay circuit module 805 does not re-establish the connection within the set delay time, the intelligent control module 803 will trigger a locking mechanism. This locks the encryption module 807, closes the data read / write interface, and encrypts the stored data to ensure data security. This completes the use of the anti-loss smart USB flash drive.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
