[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Please refer to Figures 1-4 This application provides a multi-functional integrated smart card device suitable for smart factories in chemical enterprises, comprising: Device top cover 1, wherein a fingerprint recognition module 2 is provided on the device top cover 1; The device housing 3 is detachably connected to the device top cover 1. The device housing 3 is provided with an isolation sleeve 4, a switching component and a control module 5 inside. The isolation sleeve 4 encloses the information identification module 6 and has an opening on the side away from the device top cover 1. The isolation sleeve 4 is used to block the signal of the information identification module 6. The switching component includes a first state and a second state. When it is in the first state, it blocks the opening of the isolation sleeve 4 and blocks the signal of the information recognition module 6. When it is in the second state, it opens the opening of the isolation sleeve 4. The control module 5 is electrically connected to the fingerprint recognition module 2 and the switching component respectively, and is configured to switch the switching component from the first state to the second state when the fingerprint recognition is correct.

[0021] Specifically, the device housing 3, serving as the main load-bearing structure of the device, is detachably connected to the device top cover 1. This connection facilitates the inspection and maintenance of the internal components. In this embodiment, the device housing 3 and the device top cover 1 are locked together using screws. Inside the device housing 3, several key components are housed, including an isolation sleeve 4, a switching component, and a control module 5. The isolation sleeve 4 is hollow, completely enclosing the information identification module 6 within it, and has an opening on the side of the isolation sleeve 4 furthest from the device top cover 1. The isolation sleeve 4 is made of a signal-shielding material, thus effectively blocking signals emitted by the information identification module 6 in all directions except for the opening under normal conditions, preventing unauthorized reading of information.

[0022] The switching component is the core component for controlling the opening and closing of the information identification module 6 signal. It has two working states: a first state and a second state. When the switching component is in the first state, it completely blocks the opening on the isolation sleeve 4, thus completely blocking the signal from the information identification module 6 and ensuring that information is not leaked. When the switching component is in the second state, it moves away from the opening of the isolation sleeve 4, making the opening open. At this time, the signal from the information identification module 6 can be sent out normally to complete information interaction.

[0023] The control module 5, acting as the central control unit of the entire device, is electrically connected to both the fingerprint recognition module 2 and the switching component. When a user places their finger on the fingerprint recognition module 2, the module transmits the collected fingerprint information to the control module 5, which then verifies the information. If the verification is successful, confirming the user as an authorized person, the control module 5 sends a control command to the switching component, driving it to switch from a first state to a second state, thus allowing the information recognition module 6 to transmit signals normally. If the fingerprint recognition fails, the switching component remains in the first state, continuing to block the signal from the information recognition module 6.

[0024] Furthermore, a guide groove 7 is provided on the inner sidewall of the device housing 3, and the guide groove 7 extends to the isolation sleeve 4; the switching assembly includes: A shielding plate 8 is mounted on the guide groove 7 and slidably connected to the guide groove 7. The shielding plate 8 can block the signal of the information recognition module 6. An electric push rod 9 is electrically connected to the control module 5, and its movable free end is connected to one side of the baffle plate 8.

[0025] Specifically, a guide groove 7 is provided on the inner wall of the device housing 3. This guide groove 7 extends along the inner wall of the device housing 3 to the edge of the isolation sleeve 4, providing a stable path support for the movement of the switching component. The switching component consists of a baffle plate 8 and an electric push rod 9. The baffle plate 8 is mounted on the guide groove 7, with its two sides fitting against the inner wall of the guide groove 7, allowing it to slide flexibly along the extension direction of the guide groove 7. The baffle plate 8 is made of a signal-shielding material. When it is in the position corresponding to the opening of the isolation sleeve 4, it can effectively block the signal of the information identification module 6, enhancing the signal shielding effect. The electric push rod 9, as a driving component, has its fixed end installed in the corresponding position inside the device housing 3 and is electrically connected to the control module 5, receiving control signals from the control module 5. The movable free end of the electric push rod 9 is fixedly connected to one side of the baffle plate 8. When the control module 5 issues a switching command, the electric push rod 9 will drive the baffle plate 8 to slide along the guide groove 7 through a telescopic movement, realizing the switching component's transition between the first and second states.

[0026] In this embodiment, there are two sets of electric push rods 9. Each set of electric push rods 9 consists of a micro motor 23 and a transmission screw 24. The micro motor 23 and the transmission screw 24 are driven by a threaded connection. One end of the transmission screw 24 is rotatably connected to the baffle plate 8, and the axis of rotation is the axis of the transmission screw 24. The micro motor 23 is electrically connected to the control module 5, and drives the transmission screw 24 to convert the rotation into linear motion of the baffle plate 8, thereby realizing the state switching of the switching component.

[0027] Furthermore, the side of the shield 8 away from the electric push rod 9 is provided with an elastic sealing gasket 10, and the elastic sealing gasket 10 is made of conductive rubber; when the switching component is in the first state, the elastic sealing gasket 10 is in contact with the opening edge of the isolation sleeve 4.

[0028] Specifically, an elastic sealing gasket 10 is fixedly installed on the side of the shield plate 8 away from the electric push rod 9. The elastic sealing gasket 10 is made of conductive rubber material, its shape is adapted to the edge contour of the shield plate 8, and its thickness is slightly greater than the thickness of the shield plate 8, and it has good elasticity and conductivity.

[0029] When the switching component is in the first state, the shielding plate 8 moves to the opening of the isolation sleeve 4 under the drive of the electric push rod 9. At this time, the elastic sealing gasket 10 is tightly fitted with the edge of the opening of the isolation sleeve 4. Due to the elastic properties of the elastic sealing gasket 10, it can form a tight sealing structure between the shielding plate 8 and the isolation sleeve 4, which not only enhances the shielding effect on the signal of the information identification module 6, but also further shields the signal leakage through the properties of conductive rubber. At the same time, it avoids wear caused by hard contact between the shielding plate 8 and the isolation sleeve 4, thus extending the service life of the components.

[0030] Furthermore, the device housing 3 is also provided with a limiting groove 11, and a locking block 12 for engaging with the device top cover 1 is slidably installed in the limiting groove 11. The locking block 12 is connected to the end of the electric push rod 9 away from the cover plate 8, and the engagement with the device top cover 1 is released when the switching component is in the second state.

[0031] Specifically, the device housing 3 also has two limiting grooves 11, which extend along the length of the device housing 3. The groove size is adapted to the shape of the snap-fit ​​block 12, providing stable guidance and constraint for the sliding of the snap-fit ​​block 12. The snap-fit ​​block 12 is slidably installed in the limiting groove 11, and has a snap-fit ​​part on the side facing the device top cover 1, which can cooperate with the snap-fit ​​groove at the corresponding position on the inner side of the device top cover 1 to achieve snap-fit ​​fixation. At the same time, one side of the snap-fit ​​block 12 is connected to the end of the transmission screw 24 away from the baffle plate 8. The two are synchronously linked by rotation, and the rotation axis is the axis of the transmission screw 24. Correspondingly, the device housing 3 also has a slot 22 for snap-fitting with the device top cover 1. The slot and the snap-fit ​​block 12 cooperate to realize the aligned installation of the device housing 3 and the device top cover 1.

[0032] When the switching component is in the first state, the transmission screw 24 drives the locking block 12 to be positioned close to the device top cover 1 in the limiting groove 11. At this time, the locking surface of the locking block 12 is tightly engaged with the locking groove of the device top cover 1, which securely fixes the device top cover 1 to the device housing 3. When the switching component switches to the second state under the command of the control module 5, the transmission screw 24 moves and drives the locking block 12 to slide along the limiting groove 11, so that the locking block 12 is disengaged from the locking groove of the device top cover 1, thereby releasing the fixation of the device top cover 1, which makes it convenient to disassemble the device top cover 1 for internal operation when needed.

[0033] Furthermore, a first indicator light 13 is provided on one side of the device housing 3. The first indicator light 13 is electrically connected to the control module 5. The control module 5 is also configured to control the first indicator light 13 to light up when the fingerprint recognition is incorrect.

[0034] Specifically, a first indicator light 13 is embedded on one outer wall of the device housing 3. This indicator light is electrically connected to the control module 5 via internal wiring and receives control signals from the control module 5. When a user inputs their fingerprint onto the fingerprint recognition module 2, if the fingerprint recognition module detects a mismatch, the control module 5 immediately outputs a drive signal to the first indicator light 13, causing it to illuminate and emit a red light, clearly indicating to the user that the fingerprint verification has failed. When the fingerprint verification is successful or no fingerprint verification operation has been performed, the first indicator light 13 remains off. This design allows users to quickly know the fingerprint verification result and promptly re-operate, effectively improving the device's interactive convenience.

[0035] Furthermore, a second indicator light 14 is provided on the side of the device housing 3 away from the first indicator light 13, and a contact switch 15 is provided on the inner wall of the side of the device housing 3 that abuts against the elastic sealing gasket 10. The contact switch 15 and the second indicator light 14 are electrically connected. The control module 5 is also configured to control the second indicator light 14 to light up when the elastic sealing gasket 10 is disengaged from the contact switch 15.

[0036] Specifically, a second indicator light 14 is embedded on the outer wall of the device housing 3 on the side away from the first indicator light 13. Inside the device housing 3, a contact switch 15 is fixedly installed on the inner wall on the side corresponding to the elastic sealing gasket 10. The contact switch 15 is a push-button mechanical switch with its trigger end slightly protruding from the inner wall surface. It is electrically connected to the control module 5 and the second indicator light 14 through wires to form a complete control circuit.

[0037] When the switching component is in the first state, the elastic sealing gasket 10 on the shield 8 is in close contact with the contact switch 15, and the contact switch 15 is pressed into the closed state. At this time, the control module 5 does not receive a trigger signal, and the second indicator light 14 remains off. When fingerprint recognition passes and the control module 5 drives the switching component to switch to the second state, the shield 8 moves the elastic sealing gasket 10 synchronously, causing the elastic sealing gasket 10 to disengage from the contact switch 15. The contact switch 15 automatically pops open into the open state. After detecting this state change, the control module 5 immediately outputs a control signal to light up the second indicator light 14, using green light to indicate that the user information recognition module 6 is in a working state, thus providing intuitive feedback on the device's operating status.

[0038] Furthermore, the control module 5 includes a control circuit board 16 and a battery 17. The battery 17 is electrically connected to the control circuit board 16 and is used to supply power to the control circuit board 16 and the electric push rod 9. The battery 17 is detachably connected to the device housing 3.

[0039] Specifically, the control module 5 consists of a control circuit board 16 and a battery 17, which together provide control and power supply for the device. The control circuit board 16 integrates a microprocessor, signal processing chip, and various interface circuits. It is electrically connected to the fingerprint recognition module 2, the electric actuator 9, the contact switch 15, and the indicator light assembly via wires, serving as the core control hub, responsible for receiving and processing various signals and outputting control commands. The battery 17 is electrically connected to the control circuit board 16 via a dedicated power interface, providing a stable DC power supply for the operation of the control circuit board 16 and directly powering the extension and retraction of the electric actuator 9, ensuring the normal operation of all electrical components.

[0040] The device housing 3 has a separate battery compartment corresponding to the position of the battery 17, and a pry bar is provided on one side of the battery compartment for easy removal of the battery. When it is necessary to replace or charge the battery, simply pry the battery 17 at the pry bar position to remove it from the compartment. The operation is convenient and does not require disassembling the entire device, effectively improving maintenance efficiency.

[0041] Furthermore, it also includes a positioning module 18, which is mounted on the control circuit board 16 and electrically connected to the control circuit board 16.

[0042] Specifically, it also includes a positioning module 18, which adopts a miniaturized surface mount design and is firmly installed on the reserved position of the control circuit board 16 by soldering. It forms a stable electrical connection with the control circuit board 16 and can directly receive the working power provided by the control circuit board 16 and perform data interaction to capture the geographical location information of the device in real time.

[0043] Furthermore, a bottom cover 19 is provided on the side of the device housing 3 away from the top cover 1, and an identification area mark 20 is provided on the bottom cover 19 corresponding to the opening position of the isolation sleeve 4.

[0044] Specifically, a bottom cover 19 is provided on the side of the device housing 3 away from the top cover 1, and this bottom cover is connected to the device housing 3 by welding. On the outer surface of the bottom cover 19, an identification area mark 20 is provided at the position corresponding to the opening of the isolation sleeve 4. This mark is in the form of a circle or a rectangular border. When the switching component is in the second state, the signal of the information identification module 6 can be transmitted outward through the opening of the isolation sleeve 4 and the corresponding area of ​​the bottom cover 19. The identification area mark 20 can intuitively indicate to the user the correct position to place the device close to the external identification device, avoiding identification failure due to alignment deviation, significantly improving operating efficiency, and is especially suitable for scenarios in smart factories of chemical enterprises where identity verification or authorization confirmation can be completed quickly.

[0045] Furthermore, the bottom cover 19 of the device is provided with multiple anti-slip protrusions 21.

[0046] Specifically, the anti-slip protrusions 21 are designed to improve the stability of the gripping action when the device is in use.

Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
