Description

Technical Field

[0001] The utility model relates to the technical field of security, and particularly relates to a waterproof device for a fingerprint recognition module. Background Art

[0002] A fingerprint recognition module is a device used to collect and identify human fingerprints. Based on biometric recognition technology, it extracts feature information from fingerprint images and compares it with the stored fingerprint information to achieve identity authentication and access control. Due to its high security, high reliability, and high ease of use, this technology has been widely applied in multiple fields.

[0003] Modern fingerprint recognition modules adopt advanced algorithms and sensor technologies, enabling high-precision fingerprint image acquisition and comparison to ensure the accuracy of identity recognition. The fingerprint recognition module has a fast response speed and can complete processes such as fingerprint image acquisition, preprocessing, feature extraction, and comparison in a short time, improving the user experience. As one of the human body's biometric features, fingerprints are unique and unchanging, so the fingerprint recognition module has high security. At the same time, modern fingerprint recognition modules also adopt technical means such as encrypted storage and secure encrypted transmission to ensure the security and privacy of fingerprint information. The fingerprint recognition module can adapt to the fingerprint acquisition and recognition requirements under different environmental conditions, and has a high recognition rate for dry fingers, wet fingers, fingers with shallow textures, etc. Users only need to gently place their fingers on the fingerprint recognition module to complete the identity verification process, without the need to carry additional identity verification tools or remember complex passwords and other information. However, existing fingerprint recognition modules do not have a waterproof design. If used on outdoor turnstiles, they will cause the fingerprint recognition module to fail or be damaged when used in rainy weather.

[0004] In view of this, this application proposes a waterproof device for a fingerprint recognition module. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a waterproof device for a fingerprint recognition module to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A waterproof device for a fingerprint recognition module includes a pull-up cover, a sliding cover body, a sealing gasket, and a fixed bottom plate. The pull-up cover is slidably connected to the sliding cover body. One side of the sealing gasket is fixedly connected to the sliding cover body, and the other side is fixedly connected to the fixed bottom plate.

[0008] In the above waterproof device, the sealing rubber pads are fixedly connected to the fixed bottom plate to improve the waterproofness of the device. When fingerprint recognition is required, the upper cover can be moved and pulled out to perform fingerprint recognition. After the recognition is completed, the upper cover is pulled out and slid back to its original position, which further improves the waterproofness of the device and has an anti-impact protection effect.

[0009] Furthermore, the pull-back assembly includes: a rotating rod and a coil spring. The rotating rod is rotatably connected to the drawable upper cover. One end of the coil spring is fixedly connected to the rotating rod, and the other end is fixedly connected to the convex part of the slide cover body. When the drawable upper cover moves to one end of the slide cover body, the pull-back assembly can automatically drive the drawable upper cover to return to its original position, preventing people from forgetting to reset the drawable upper cover, greatly improving the automatic degree of the device, saving manpower, and preventing damage to the device.

[0010] Furthermore, it also includes a limiting circular slider. One end of the limiting circular slider is slidably connected to the limiting slide groove provided on the drawer cover, and the other end is installed in the straight slide groove provided on the slide cover body, and the limiting slide groove is perpendicular to the straight slide groove. The limiting slide groove can limit the limiting circular slider to move along the straight slide groove to drive the drawer cover to move, thereby improving the controllability of the device.

[0011] Furthermore, the sliding cover body is provided with an "S"-shaped sliding groove, and the two ends of the "S"-shaped sliding groove (12) are respectively connected to the two ends of the straight sliding groove (13). Together with the "S"-shaped sliding groove, when the upper cover is moved to one end of the sliding cover body and starts to reset, the limited circular sliding cover moves along the "S"-shaped sliding groove. The "S"-shaped sliding groove slows down the reset speed of the upper cover, and fingerprint recognition can be performed during this period, which greatly improves the dexterity of the device.

[0012] Furthermore, a fingerprint recognition module is included. The fingerprint recognition module is installed in a card slot provided on the sliding cover body. Installing the card slot is more convenient for people to perform fingerprint detection. When there is damage and needs to be replaced, it can be disassembled, and the maintenance cost of the device is reduced, which is convenient for maintenance.

[0013] Furthermore, it also includes a fingerprint recognition module pressing block. The fingerprint recognition module pressing block is fixedly connected to the slide cover body, and the fingerprint recognition module is located between the fingerprint recognition module pressing block and the slide cover body. The fingerprint recognition module pressing block improves the stability of the fingerprint recognition module, ensuring that it will not loosen or shift due to vibration, movement or other external factors, helping to ensure the accuracy and reliability of fingerprint recognition, avoiding recognition errors or failures caused by module shaking, and improving the stability of device operation.

[0014] Furthermore, the sealing rubber pad material can be any one of silicone rubber, fluororubber, nitrile rubber, and polyurethane. Different materials can be selected according to different environmental locations, which not only improves the waterproofness of the device, but also increases the service life.

[0015] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is as follows:

[0016] 1. For the fingerprint recognition module waterproof device of the present utility model, the sealing rubber pads are fixedly connected to the fixed bottom plate respectively, which improves the waterproof performance of the device. When fingerprint recognition is required, the pull-up cover can be moved and then fingerprint recognition can be carried out. After the recognition is completed, the pull-up cover is slid back to its original position, which further improves the waterproof performance of the device and has an anti-impact protection function.

[0017] 2. Through the cooperation of the return force component and each chute and the limit circular slider, the pull-up cover of the present utility model can be quickly moved to one end of the sliding cover body and then perform a slow reset movement. Fingerprint recognition can be carried out during the reset movement, which greatly improves the flexibility of the device, has a high degree of automation, and can prevent water from entering and damaging the device due to human forgetting to reset the pull-up cover.

[0026] The present utility model will be further described in detail below with reference to the embodiments:

[0027] Embodiment 1: Please refer to Figures 1-6, this embodiment provides a waterproof device for a fingerprint recognition module, which includes a pull-up cover 1, a sliding cover body 3, a fingerprint recognition module 4, screws 6, and a sealing gasket 7. It may also include a return force component, a fixed bottom plate 8, a limiting circular slider 10, a limiting chute 11, an "S"-shaped chute 12, and a straight chute 13.

[0028] The pull-up cover 1 is slidably connected to the sliding cover body 3. The pull-up cover 1 is square with rounded corners on all four sides to prevent sharp edges from causing damage to the hands during operation. The pull-up cover 1 can be made of aluminum alloy, which has high strength and corrosion resistance, ensuring the stability and durability of the pull-up cover 1 during long-term use. At the same time, aluminum alloy also has a relatively light weight, which helps to reduce the overall weight of the device. Applying a layer of lubricant at the joint between the pull-up cover 1 and the sliding cover body 3 helps the sliding between the pull-up cover 1 and the sliding cover body 3 and reduces friction.

[0029] One side of the sealing gasket 7 is fixedly connected to the sliding cover body 3, and the other side is fixedly connected to the fixed bottom plate 8, which can prevent water from entering the fingerprint recognition module and has a protective effect on the fingerprint recognition module. The material of the sealing gasket 7 can be any one of silicone rubber, fluororubber, nitrile rubber, and polyurethane. Silicone rubber material has high temperature resistance and corrosion resistance, and has excellent sealing performance. Fluororubber material has good oil resistance and chemical resistance, and at the same time has good high temperature resistance and corrosion resistance. Polyurethane material has a relatively affordable price and is suitable for conventional sealing requirements. However, it is slightly insufficient in terms of high temperature and corrosion resistance. Different materials can be used according to the different usage site environments to improve the service life of the sealing gasket 7.

[0030] The return force component includes a rotating rod 9 and a coil spring 2. The rotating rod 9 is rotatably connected to the pull-up cover 1. One end of the coil spring 2 is fixedly connected to the rotating rod 9, and the other end is fixedly connected to the convex part of the sliding cover body 3. When the pull-up cover 1 is pulled, it drives the coil spring 2 to deform and store energy, which can reset the pull-up cover 1, greatly improving the dexterity and convenience of the device.

[0031] The material of the coil spring 2 can be chrome vanadium steel. By adding vanadium elements, the structure of the steel can be refined, and the strength and toughness of the steel can be improved. It has good anti-fatigue and anti-impact performance and can work reliably within a wide temperature range. When an external force acts on the coil spring 2, the coil spring 2 will deform and store energy. When the external force is removed, the coil spring 2 will return to its original shape and release the stored energy. The precise design and manufacture of the coil spring 2 can ensure the high efficiency and stability of the mechanical equipment during operation. By storing and releasing energy, the coil spring 2 can reduce the direct friction and impact between mechanical components, thereby extending the service life of the equipment. The compact design of the coil spring 2 enables it to provide a large restoring force in a small space. This characteristic makes the coil spring 2 the preferred solution for many space-limited applications.

[0032] An operation instruction diagram can be attached to the surface of the pull-out upper cover 1. Through clear steps and processes, the operation instruction diagram helps users or executors quickly understand and follow the correct operation sequence. This reduces errors caused by misunderstandings or forgotten steps, thereby improving work efficiency and accuracy.

[0033] One end of the limit circular slider 10 is slidably connected to the limit chute 11 provided on the pull-out upper cover 1, and the other end is installed in the straight chute 13 provided on the sliding cover body 3. The limit chute 11 enables the limit circular slider 10 to slide only in two directions. The sliding cover body 3 is provided with an "S"-shaped chute 12. The "S"-shaped chute 12 provided on the sliding cover body 3 communicates with the straight chute 13, and the limit circular slider 10 can continuously move within the "S"-shaped chute 12 and the straight chute 13. When the pull-out upper cover 1 is pulled, the limit circular slider 10 moves within the straight chute 13, enabling the pull-out upper cover 1 to move quickly. The "S"-shaped chute 12 increases the travel of the limit circular slider 10, helping the pull-out upper cover 1 to return at a slower speed. The limit circular slider 10 is a cylinder, which helps it move within the straight chute 13 and the "S"-shaped chute 12, reducing friction.

[0034] The fingerprint recognition module 4 is installed in the card slot provided on the sliding cover body 3. A layer of waterproof glue is applied at the joint between the fingerprint recognition module 4 and the sliding cover body 3, which helps protect the fingerprint recognition module 4 from water ingress and damage. The card slot provided on the sliding cover body 3 conforms to the shape of the human finger, making it more convenient for people to perform fingerprint detection, and it is simple, clear, and easy to identify. The sliding cover body 3 is made of stainless steel. Stainless steel is well-known for its excellent corrosion resistance and can resist the erosion of various chemical substances, including acids, alkalis, salts, etc. Although the main advantages of stainless steel lie in its corrosion resistance and strength, its good mechanical properties also endow it with a certain impact resistance, making the sliding cover body 3 have a longer service life and providing good protection for internal components.

[0035] The fingerprint recognition module pressing block 5 is fixedly connected to the sliding cover body 3, and the fingerprint recognition module 4 is installed between the fingerprint recognition module pressing block 5 and the sliding cover body 3. The fingerprint recognition module 4 is clamped by the fingerprint recognition module pressing block 5 and the sliding cover body 3. The fingerprint recognition module pressing block 5 physically fixes the fingerprint recognition module 4 in place on the sliding cover body 3 to ensure that it will not loosen or shift due to vibration, movement, or other external factors. The stable fixation helps to ensure the accuracy and reliability of fingerprint recognition and avoid recognition errors or failures caused by module shaking. The fingerprint recognition module pressing block 5 may also play a role in evenly transmitting the force of the user's finger press to the fingerprint recognition sensor. This helps to ensure that the sensor can fully contact and capture the detailed information of the fingerprint, improving the accuracy and speed of recognition. The fingerprint recognition module pressing block 5 can also help the fingerprint recognition module 4 better adapt to the finger sizes and shapes of different users, as well as different pressing methods and forces. This helps to enhance the user experience and enables users to complete the fingerprint recognition process more easily and accurately. One side of the fingerprint recognition module pressing block 5 has the same shape as the fingerprint recognition module 4 to better fix the fingerprint recognition module 4, and the other side has a slightly larger area and threaded holes for fixing to the sliding cover body 3.

[0036] Multiple screws 6 can effectively connect and fix two or more components. The connection of the screws 6 is detachable, which means that when the device needs to be repaired, replaced, or adjusted, the screws 6 can be easily disassembled without causing irreversible damage to the original structure. This flexibility greatly extends the service life of the device and reduces the maintenance cost. The screws 6 are made of stainless steel and are painted on the surface to improve their corrosion resistance, wear resistance, and aesthetics, preventing the screws 6 from being damaged and unable to be disassembled.

[0037] The working principle of the fingerprint recognition module waterproof device is specifically described as follows: When fingerprint recognition is required, the pull-up cover 1 is pulled to one end of the sliding cover body 3. At the same time, the limit circular slider 10 slidably connected to the limit chute 11 moves to one end in the straight chute 13, and the coil spring 2 of the return force assembly is stretched to store energy. Then, under the action of the return force assembly, the limit circular slider 10 slowly drives the pull-up cover 1 to perform a reset movement along the "S"-shaped chute 12. During the reset movement, fingerprint recognition is performed. When the fingerprint recognition is completed, the pull-up cover 1 automatically returns to its original position, greatly improving the automation and dexterity of the device and protecting the device. The sealing gasket 7 is fixedly connected between the sliding cover body 3 and the fixed bottom plate 8 to further protect the device from water. The fixed connection of multiple components is achieved through the screws 6. When a component is damaged and needs to be replaced, the detachable screws 6 can be used to replace the component. This reduces the maintenance cost. Generally speaking, the fingerprint recognition module waterproof device of this embodiment has the characteristics of excellent waterproofness, dexterity, and convenient maintenance.

[0038] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made to it, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit of the present utility model are within the protection scope of the present utility model.
