Description

Technical Field

[0001] The utility model relates to the technical field of electronic products, and in particular to a software loading and software encryption device with expansion functions. Background Art

[0002] Data security is an important part of information security. Encryption is required for both storage and transmission to ensure information security. The most commonly used encryption methods are software encryption using algorithm encryption, which is easily cracked by brute force. The other is hardware encryption, which uses physical devices to limit reading and writing capabilities. It can provide good protection for electronic information and software, and can also prevent the file itself from being tampered with.

[0003] In the field of route planning software and route safety verification, traditional encryption devices can ensure the security of route data, but sometimes other functional components (such as positioning modules) need to be loaded according to needs for use. Therefore, it is necessary to add an expansion interface to the encryption device to externally load functional components with expansion requirements. For example, Publication No. CN203659436U discloses a multifunctional USB flash drive, which is provided with an expansion USB socket on the rear side of the USB flash drive body for expansion and connection of other functional components. However, the following problems still exist:

[0004] 1. Some extended functions cannot be directly connected via USB interface;

[0005] 2. The expansion socket is always in contact with the outside world, and is easily affected by factors such as the external environment, causing corrosion at the connection point. The socket is also prone to dust or water ingress, causing poor contact;

[0006] 3. In addition, the expansion component is easy to fall off when it is directly plugged into the expansion socket, which affects the use;

[0007] 4. The expansion socket has no protection device to prevent outsiders from arbitrarily expanding components, which may cause data to be cracked. Utility Model Content

[0032] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0033] As shown in the figure, this embodiment provides a software loading and software encryption device with expansion function, including a shell 1, a USB interface 2 arranged on one side of the shell 1 and an expansion component 3 that can be plugged into the shell 1; the shell 1 is provided with a slot 4 for plugging the expansion component 3, and the top of the slot 4 is provided with a flip cover 5; one end of the cover 5 is provided with a shaft rod 6, and the cover 5 is rotatably connected to the shell 1 through the shaft rod 6, and the other end of the cover 5 is provided with a slide groove 7, and an L-shaped rod 8 is slidably installed in the slide groove 7, and a return spring 9 is also provided in the slide groove 7, so that The two ends of the reset spring 9 are fixedly connected to the inner wall of the slide groove 7 and the L-shaped rod 8 respectively; a connecting buckle 10 is fixedly arranged at one end of the L-shaped rod 8 away from the cover plate 5; a card slot 11 matching the connecting buckle 10 is arranged on the side wall of the shell 1; a locking assembly 12 is arranged on the shaft rod 6, and the locking assembly 12 can lock the shaft rod 6 so that the shaft rod 6 cannot rotate; a fingerprint recognition module 13 is embedded on the side wall of the shell 1, and the fingerprint recognition module 13 is electrically connected to a control module, and the control module is used to control the locking assembly 12 to lock the shaft rod 6 and release the shaft rod 6.

[0034] When the expansion assembly 3 is not installed, the cover plate 5 is closed in the slot 4. The cover plate 5 is fixedly sealed on the slot 4 by the cooperation of the L-shaped rod 8, the return spring 9, the connecting buckle 10 and the card slot 11 to prevent the external environment from damaging the connection structure in the slot 4. When the cover plate 5 needs to be opened, the cover plate 5 can be opened by pulling the L-shaped rod 8 to make the connecting buckle 10 leave the card slot 11;

[0035] In order to improve the safety of the device, an axis rod 6 is set at one end of the cover 5, and the axis rod 6 is locked by a locking assembly 12, so that the axis rod 6 cannot rotate, thereby making the cover 5 unable to open, thereby improving the safety of the device and preventing irrelevant personnel from arbitrarily expanding and installing the expansion assembly 3. When the expansion assembly 3 needs to be installed, fingerprint recognition can be performed through the fingerprint recognition module 13 on the outer shell 1, and the locking assembly 12 is controlled by the fingerprint recognition module 13 and the control block to release the axis rod 6, so that the axis rod 6 can rotate, thereby allowing the cover 5 to be opened.

[0036] The expansion component 3 is an independent body, and can be loaded with components such as GPS or Beidou positioning chips, as well as gyroscopes or other functional sensors, alarms and other components. It is not just a mobile storage device connected by USB. The expansion interface set in the slot 4 can be connected to the expansion function module in the expansion component 3. The common USB interface 22 can be used, but an interface connected to the expansion function module must be set in the expansion shell. For some simple expansion functions, it is also possible to use the expansion function without connecting the expansion component 3 to meet the needs of users under different conditions.

[0037] Among them, the locking assembly 12 includes a protrusion 14, a magnetic metal ring 15 and an electromagnet 16; the protrusion 14 is fixed on one end of the shaft rod 6, the magnetic metal ring 15 is slidably sleeved on the shaft rod 6, and the inner side of the magnetic metal ring 15 is provided with a limit opening 24 that cooperates with the protrusion 14, the electromagnet 16 is fixed on one end of the shaft rod 6, the control module is electrically connected to the electromagnet 16, and an elastic pad is provided between the electromagnet 16 and the magnetic metal ring 15.

[0038] When the expansion component 3 is not loaded, the protrusion 14 is located in the limit groove 21, and the shaft 6 is locked by the limit opening 24 of the magnetic metal ring 15 to prevent the cover 5 from rotating. When the user needs to rotate the cover 5 to load the expansion component 3 or remove the expansion component 3, the user needs to be authenticated by the fingerprint recognition module 13, and then the fingerprint recognition module 13 cooperates with the control module to control the electromagnet 16. When the electromagnet 16 is started, the magnetic metal ring 15 is driven to move in the direction of the electromagnet 16, so that the protrusion 14 is separated from the limit opening 24, and after the user rotates the cover 5, the protrusion 14 is stuck in the limit opening 24, and the elastic pad is used to assist the magnetic metal ring 15 to reset. It should be noted that in this design, according to the actual usage scenario, a battery can be set in the shell to power the fingerprint recognition module 13, the electromagnet 16 and other components, or a capacitor can be set in the shell, and after the cover encryption device is connected to the device, the USB interface 2 is used for power supply.

[0039] In order to prevent the expansion component 3 from falling off during use after being inserted into the slot 4, the expansion component 3 includes a main shell 17, and the bottom end of the main shell 17 is provided with a connecting shell 18 that cooperates with the slot 4; the connecting shell 18 is provided with an elastic sheet 19 on the side close to the card slot 11, and the lower end of the elastic sheet 19 is fixed with a buckle 20, and the buckle 20 can be snapped into the card slot 11; the side of the main shell 17 away from the card slot 11 is provided with a limiting groove 21 that matches the connecting buckle 10.

[0040] After the expansion component 3 is inserted into the slot 4, the connecting buckle 10 on the cover plate 5 is engaged with the limiting groove 21, and the engaging groove 11 is engaged with the buckle 20, so that the expansion component 3 is fixed on the slot 4, and the expansion function module is stably connected and not easy to fall off during use.

[0041] A knocking block is fixed on the L-shaped rod 8, and an arc plate matching the knocking block is embedded on the side walls of the shell 1 and the main shell 17. The arc plate is made of metal, and the knocking block is arranged to match the arc plate. When installing and removing the expansion component 3, when the connecting buckle 10 is close to the limit groove 21 or the card slot 11, the connecting buckle 10 respectively abuts against the main shell 17 and the shell 1, and drives the L-shaped rod 8 to move. When the connecting buckle 10 is inserted into the limit groove 21 or the card slot 11, the L-shaped rod 8 rebounds and drives the knocking block to knock on the arc plate, thereby making a sound, which helps the user to judge whether the clamping is completed, and plays a certain prompting role.

[0042] In the above scheme, since the connecting buckle 10 needs to be engaged with both the limiting groove 21 and the clamping slot 11, the limiting groove 21 and the clamping slot 11 of the same shape and size are used, and the connecting buckle 10 and the clamping buckle 20 can also be designed with the same shape and size.

[0043] Furthermore, a groove 22 matching the expansion component 3 is provided at the top of the shell 1, and a recessed groove 23 matching the cover plate 5 is provided in the groove 22. The groove 22 can better fix the expansion component 3 and facilitate the user to intuitively see whether the expansion component 3 is clamped. The recessed groove 23 is provided to accommodate the cover plate 5 after the expansion component 3 is installed, ensuring that the main shell 17 of the expansion shell is partially located in the groove 22.

[0044] The present invention is described by preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the claims of this application are within the scope of protection of the present invention.
