Description
Technical Field
[0001] This utility model belongs to the technical field of fingerprint recognition devices, and more specifically, it relates to a fingerprint recognition device for intelligent buildings. Background Technology
[0002] Fingerprint recognition devices for smart buildings are high-tech identity verification devices primarily used in intelligent building environments. They verify user identity by recognizing their fingerprints, thereby enabling various functions such as access control and attendance management. They can accurately distinguish the fingerprint characteristics of different individuals, using this as the basis for identity verification.
[0003] Fingerprint recognition devices for smart buildings are typically installed at the entrances and exits of the building. Since these devices are mostly exposed, the sensing area can easily become dusty and scratched over time, affecting recognition accuracy.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] In view of the problems in related technologies, this utility model proposes a fingerprint recognition device for intelligent buildings to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is a fingerprint recognition device for intelligent buildings, including a fingerprint recognition component. Two blocking components are symmetrically arranged on the outer surface of the fingerprint recognition component, and a pressing and pushing component is arranged between the two blocking components. An elastic guiding component is arranged inside the fingerprint recognition component, and the guiding end of the elastic guiding component is connected to the pressing and pushing component.
[0008] The blocking component is used to block the fingerprint recognition component. The pressing and pushing component moves downward while pushing the blocking component so that the blocking component no longer blocks the fingerprint recognition component. The elastic guiding component is used to push the pressing and pushing component upward.
[0009] Furthermore, the fingerprint recognition component includes a main body, a mounting groove is provided on the top of the main body, a recognition module is fixedly connected to the bottom of the inner wall of the mounting groove, and a fixing ear plate is fixedly connected to the back of the main body.
[0010] Furthermore, the shielding assembly includes a C-shaped shielding plate, which is sleeved on the outer surface of the main body. Storage cavities are provided on both sides of the main body. A movable disk is movably connected inside the storage cavity. A movable rod is fixedly connected to one side of the movable disk. The movable rod passes through the storage cavity and is fixedly connected to the C-shaped shielding plate.
[0011] Furthermore, the pressing and pushing assembly includes a moving groove, which is provided on both C-shaped baffles. An L-shaped moving plate is movably connected inside the moving groove. A pushing plate is fixedly connected to the back of the C-shaped baffles. A pushing groove is provided on one side of the pushing plate. A movable rod is movably connected inside the pushing groove. A pushing rod is fixedly connected to the inner side of the L-shaped moving plate. The pushing rod and the movable rod are rotatably connected.
[0012] Furthermore, a pressing block is fixedly connected to the top of the L-shaped movable plate, and an arc-shaped pressing groove is formed on the top of the pressing block.
[0013] Furthermore, the elastic guide assembly includes a buffer groove, which is formed at the bottom of the inner wall of the mounting groove. A T-shaped guide rod is fixedly connected to the bottom of the inner wall of the buffer groove. A movable frame is movably connected to the outer surface of the T-shaped guide rod. The movable frame is fixedly connected to an L-shaped movable plate. A spring is fixedly connected between the bottom of the movable frame and the inner wall of the buffer groove.
[0014] Furthermore, a shielding frame is fixedly installed on the top of the main body, and a through groove is opened at the bottom of the shielding frame, with the U-shaped shielding plate movably connected to the through groove.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model involves pressing the pressing and pushing component downwards, causing it to move downwards while simultaneously blocking the lateral movement of the blocking component. This prevents the blocking component from obstructing the fingerprint recognition component, allowing the operator to contact the sensing end of the fingerprint recognition component while the pressing and pushing component is in use. The two blocking components ensure that the sensing end of the fingerprint recognition component is not directly exposed when not in use, effectively preventing scratches and dust accumulation on its surface and thus guaranteeing the recognition accuracy of the fingerprint recognition component.
[0017] 2. This utility model involves moving the finger out of the arc-shaped pressing groove. At this time, the spring can push the L-shaped moving plate upward through the moving frame. Simultaneously, the push rod on the L-shaped moving plate can drive the movable rod to move inside the pushing groove. When the pressing block moves out of the mounting groove, the movable rod pulls the two C-shaped shields through the inclined groove inside the pushing groove, causing the C-shaped shields to block the main body. The above arrangement allows the pressing block to be pressed directly during fingerprint recognition. When the pressing block is no longer pressed, the L-shaped moving plate and the C-shaped shields can automatically reset, thus ensuring the protective effect of the two C-shaped shields recognition module.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0030] Please see Figures 1-6 As shown, this utility model is a fingerprint recognition device for intelligent buildings, including a fingerprint recognition component 1. Two blocking components 2 are symmetrically arranged on the outer surface of the fingerprint recognition component 1. A pressing and pushing component 3 is arranged between the two blocking components 2. An elastic guiding component 4 is arranged inside the fingerprint recognition component 1. The guiding end of the elastic guiding component 4 is connected to the pressing and pushing component 3.
[0031] The blocking component 2 is used to block the fingerprint recognition component 1. The pressing and pushing component 3 moves downward while pushing the blocking component 2 so that the blocking component 2 no longer blocks the fingerprint recognition component 1. The elastic guiding component 4 is used to push the pressing and pushing component 3 upward.
[0032] During fingerprint recognition, the operator places their finger on the top of the pressing and pushing component 3 and then presses it downwards. At this time, the pressing and pushing component 3 can push the two blocking components 2 laterally, so that the two blocking components 2 no longer block the fingerprint recognition component 1. As the operator continues to press the pressing and pushing component 3 downwards, the operator's finger can directly contact the sensing end of the fingerprint recognition component 1, thereby completing the identity recognition. When the operator moves their finger off the pressing and pushing component 3, the blocking components 2 and the pressing and pushing component 3 can be reset under the action of the elastic end of the elastic guide component 4.
[0033] By pressing down on the pressing and pushing component 3, the blocking component 2 is no longer obstructing the fingerprint recognition component 1. At the same time, the operator makes contact with the sensing end of the fingerprint recognition component 1 under the pressure of the pressing and pushing component 3. After the identity recognition is completed, when the operator moves his finger off the pressing and pushing component 3, the pressing and pushing component 3 and the blocking component 2 can automatically reset under the action of the elastic guide component 4. In the above setting, the two blocking components 2 ensure that the sensing end of the fingerprint recognition component 1 is not directly exposed to the outside when not in use, effectively avoiding scratches and dust accumulation on the surface of the sensing end of the fingerprint recognition component 1, thereby ensuring the recognition accuracy of the fingerprint recognition component 1.
[0034] In one embodiment, the fingerprint recognition component 1 includes a main body 101, a mounting groove 102 is provided on the top of the main body 101, a recognition module 103 is fixedly connected to the bottom of the inner wall of the mounting groove 102, and a fixing ear plate 104 is fixedly connected to the back of the main body 101.
[0035] The main body 101 can be installed in a suitable position by fixing the ear plate 104. When performing identity recognition, the operator's finger can move from the top of the main body 101 to the inside of the mounting slot 102 and then directly contact the recognition module 103 inside the mounting slot 102 to complete the identity recognition.
[0036] In one embodiment, the shielding component 2 includes a U-shaped shielding plate 201, which is sleeved on the outer surface of the main body 101. The main body 101 has storage cavities 202 on both sides. A movable disk 203 is movably connected inside the storage cavity 202. A movable rod 204 is fixedly connected to one side of the movable disk 203. The movable rod 204 passes through the storage cavity 202 and is fixedly connected to the U-shaped shielding plate 201.
[0037] By moving the two C-shaped baffles 201, the two C-shaped baffles 201 slide within the storage cavity 202 via the corresponding moving rods 204, thereby preventing the two C-shaped baffles 201 from obstructing the main body 101. Simultaneously, the moving rods 204 ensure the stability of the C-shaped baffles 201 during movement. Furthermore, with the moving rods 203 and the storage cavity 202 in their positions, the moving rods 204 will not detach from the storage cavity 202, thus preventing the two C-shaped baffles 201 from detaching from the main body 101 during movement.
[0038] In one embodiment, the pressing and pushing assembly 3 includes a moving groove 301, which is provided on both U-shaped baffles 201. An L-shaped moving plate 302 is movably connected inside the moving groove 301. A pushing plate 308 is fixedly connected to the back of the U-shaped baffles 201. A pushing groove 303 is provided on one side of the pushing plate 308. A movable rod 304 is movably connected inside the pushing groove 303. A pushing rod 305 is fixedly connected to the inner side of the L-shaped moving plate 302. The pushing rod 305 is rotatably connected to the movable rod 304.
[0039] The push groove 303 consists of an inclined groove and a vertical groove. During fingerprint recognition, the operator places their finger on the top of the L-shaped moving plate 302 and presses it downwards. At this time, the push rod 305 on the L-shaped moving plate 302 can drive the movable rod 304 to slide in the inclined groove of the push groove 303. Simultaneously, the movable rod 304 can push the C-shaped shield 201 through the inclined groove, allowing the C-shaped shield 201 to move outwards from the main body 101, thus removing the obstruction from the top of the mounting groove 102. When the movable rod 304 moves into the vertical groove inside the push groove 303 under the action of the push rod 305, the two C-shaped shields 201 stop moving. At the same time, the operator's finger moves into the mounting groove 102. With continuous downward pressure on the L-shaped moving plate 302, the operator's finger can come into contact with the recognition module 103. The movable rod 304, which can rotate on the push rod 305, is designed such that when the movable rod 304 pushes the U-shaped baffle 201 through the push groove 303, the friction between the movable rod 304 and the push groove 303 is small.
[0040] In one embodiment, for the L-shaped movable plate 302, a pressing block 306 is fixedly connected to the top of the L-shaped movable plate 302, and an arc-shaped pressing groove 307 is formed on the top of the pressing block 306.
[0041] The pressing block 306 is located at the top of the main body 101. When the L-shaped movable plate 302 is pressed downwards, the middle of the operator's finger can be placed directly inside the arc-shaped pressing groove 307. This design prevents the finger from wobbling on the pressing block 306 when pressing the L-shaped movable plate 302. When the operator's finger is about to move to the top of the C-shaped baffle 201, the movable rod 304 also moves from the inclined groove on the pushing groove 303 to the inside of the vertical groove, so that the two C-shaped baffles 201 will not obstruct the finger when it moves into the mounting groove 102.
[0042] In one embodiment, the elastic guide assembly 4 includes a buffer groove 401, which is formed at the bottom of the inner wall of the mounting groove 102. A T-shaped guide rod 402 is fixedly connected to the bottom of the inner wall of the buffer groove 401. A movable frame 403 is movably connected to the outer surface of the T-shaped guide rod 402. The movable frame 403 is fixedly connected to an L-shaped movable plate 302. A spring 404 is fixedly connected between the bottom of the movable frame 403 and the inner wall of the buffer groove 401.
[0043] When the L-shaped movable plate 302 moves downward, the movable frame 403, driven by the L-shaped movable plate 302, can press the spring 404 downward. Simultaneously, guided by the T-shaped guide rod 402, it moves downward along with the L-shaped movable plate 302. The two T-shaped guide rods 402 guide the L-shaped movable plate 302 through the movable frame 403, ensuring the stability of the L-shaped movable plate 302 during movement. After fingerprint recognition is complete, the operator directly moves their finger out of the arc-shaped pressing groove 307. At this time, the spring 404 can push the movable frame 403 upward, causing the movable frame 403 to move the L-shaped movable plate 302 upward. Simultaneously, the push rod 305 on the L-shaped movable plate 302 can drive the movable rod 304 to move inside the push groove 303, allowing the two U-shaped blocking plates 201 to automatically reset.
[0044] In one embodiment, for the main body 101, a shielding frame 5 is fixedly installed on the top of the main body 101, and a through groove 6 is opened at the bottom of the shielding frame 5. The U-shaped shielding plate 201 is movably connected to the through groove 6.
[0045] The C-shaped shield 201 can move inside the through groove 6, and the shielding frame 5 can shield the top of the two C-shaped shields 201. This arrangement makes it less likely for dust to accumulate on the top of the two C-shaped shields 201. The two C-shaped shields 201 and the shielding frame 5 work together to improve the overall dustproof effect of the fingerprint recognition device.
[0046] Through the above technical solution, 1. By pressing down on the pressing and pushing component 3, the pressing and pushing component 3 moves downward while simultaneously blocking the component 2 from moving laterally, so that the blocking component 2 no longer blocks the fingerprint recognition component 1. At this time, the operator can contact the sensing end of the fingerprint recognition component 1 while the pressing and pushing component 3 is pressed down. In the above setting, the two blocking components 2 ensure that the sensing end of the fingerprint recognition component 1 is not directly exposed to the outside when not in use, effectively avoiding scratches and dust accumulation on the surface of the sensing end of the fingerprint recognition component 1, thereby ensuring the recognition accuracy of the fingerprint recognition component 1; 2. By moving the finger out of the arc-shaped pressing groove 307, the spring 404 moves... The frame 403 can push the L-shaped movable plate 302 upwards. At the same time, the push rod 305 on the L-shaped movable plate 302 can drive the movable rod 304 to move inside the push groove 303. When the pressing block 306 moves out of the mounting groove 102, the movable rod 304 pulls the two C-shaped shields 201 through the inclined groove inside the push groove 303, so that the C-shaped shields 201 block the main body 101. The above arrangement allows the pressing block 306 to be pressed directly during fingerprint recognition. At the same time, when the pressing block 306 is not pressed, the L-shaped movable plate 302 and the C-shaped shields 201 can automatically reset, thereby ensuring the protective effect of the two C-shaped shields 201 on the recognition module.
