Description

Technical Field

[0001] The utility model relates to the technical field of fingerprint collection, and in particular to a novel fingerprint collection module. Background Art

[0002] Fingerprint collection is the process of capturing and storing fingerprint images or related data using specific equipment and technologies. A fingerprint is a unique biometric characteristic of each person, consisting of the ridges and valleys on the finger's surface. Its detailed features, including lines, endpoints, and bifurcations, are highly unique and stable. With the development of smart homes and wearable devices, the demand for fingerprint collection modules has gradually expanded from traditional scenarios to everyday life, necessitating the use of new fingerprint collection modules.

[0003] New fingerprint acquisition modules can be divided into many types, including optical fingerprint acquisition modules, capacitive fingerprint acquisition modules and ultrasonic fingerprint acquisition modules. New fingerprint acquisition modules cover a variety of types, from common optical and capacitive types to more advanced ultrasonic, thermal, flexible modules, and multi-mode modules with fusion technology. In the capacitive fingerprint acquisition module, the unevenness of the fingerprint surface is used to change the electric field distribution. The fingerprint image is recorded by detecting these changes. The capacitor array senses the electric field changes at each point and generates a corresponding fingerprint image.

[0004] Existing fingerprint acquisition modules often require tools such as bolts to secure them during assembly, making the process complex and time-consuming. Furthermore, in terms of sealing, the seals and components in traditional designs often struggle to perfectly fit the gaps between each interface, allowing impurities such as dust and moisture to enter the device, shortening the lifespan of the fingerprint module and even causing damage. These issues complicate the installation and maintenance of fingerprint acquisition modules, impacting device reliability and user experience. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1-Figure 3 The present invention provides an embodiment of a novel fingerprint collection module, comprising:

[0035] Shell 1 is used to support the whole and provide stable support and protection for the internal components. A connecting groove 5 is opened inside the shell 1, and the connecting groove 5 is used to cooperate with the connecting ring 8 to achieve a stable connection of the overall structure;

[0036] Mainboard 2, the top of which is electrically connected to a fingerprint module 4, which is used to receive fingerprint information and perform preliminary collection. The outer wall of the mainboard 2 is electrically connected to a flat cable 3, which is used to transmit the collected fingerprint information to an external device or control unit. The mainboard 2 is used to process fingerprint data and optimize and transmit the data. The mainboard 2 is installed inside the housing 1 and is ensured to be stable and removable in the housing 1 by a sliding connection.

[0037] Double-sided wedge-shaped sealing ring 7, which is used to seal between the housing 1 and the fingerprint module 4 to prevent external dust and moisture from entering the housing 1 and affecting the performance of the fingerprint module 4. The outer wall of the double-sided wedge-shaped sealing ring 7 is fixedly connected to a connecting ring 8, which is used to connect the double-sided wedge-shaped sealing ring 7 and the housing 1 to further enhance the stability and durability of the sealing ring. A groove 9 is opened inside the connecting ring 8, which is used to cooperate with the convex ring 6 to ensure sealing performance;

[0038] The convex ring 6, the bottom of the convex ring 6 is fixedly connected to the inside of the shell 1, and the convex ring 6 forms a tight fit by fitting with the groove 9, thereby effectively improving the sealing between the connecting ring 8 and the shell 1, preventing external factors from affecting the normal operation of the internal components. The mainboard 2 is slidably connected to the inside of the shell 1. In this way, the convenience of installation and maintenance of the mainboard 2 is ensured. The fingerprint module 4 is slidably connected to the inside of the shell 1. The sliding structure further improves the accuracy and convenience of installation of the fingerprint module 4. The connecting ring 8 is fitted with the connecting groove 5 to ensure the firmness and reliability of the connection. The inner wall of the double-sided wedge-shaped sealing ring 7 is fitted to the outer wall of the fingerprint module 4. The fitting structure can effectively prevent the generation of gaps and improve the overall sealing performance.

[0039] Specifically, the double-sided wedge-shaped sealing ring 7 is tightly embedded in the connecting groove 5 through the connecting ring 8, ensuring the precise fit between the connecting ring 8 and the housing 1, further enhancing the sealing performance of the connection. At the same time, the housing 1 and the connecting ring 8 are firmly embedded in the groove 9 through the convex ring 6 inside the housing 1, forming a stable physical lock, further improving the overall sealing performance and preventing the intrusion of external impurities such as dust and moisture. During the installation process, the mainboard 2 is firmly installed in the housing 1, ensuring the stability of each component and the compactness of the structure. The fingerprint module 4 extends from the housing 1 through a clever design, and its sealing is further enhanced by the precise fit between the double-sided wedge-shaped sealing ring 7 and the housing 1, ensuring that there is no gap between the fingerprint module 4 and the housing 1. This design not only effectively improves the sealing performance of the entire device, but also enhances the protection capability of the device in complex environments, prevents the influence of dust, moisture, etc. on the internal components, and improves the durability and reliability of the device.

[0040] Reference Figure 4 and Figure 5, a card slot 11 is opened inside the shell 1, and the card slot 11 is used to cooperate with the card block 15 to achieve a stable installation of the bottom plate 12; a limit block 10 is fixedly connected to the inside of the shell 1, and the limit block 10 is used to limit and fix the main board 2, thereby ensuring the stability of the position of the main board 2 inside the shell 1 and preventing the main board 2 from loosening or shifting due to external force. The limit block 10 is buckled with the main board 2, and the buckling method further improves the firmness of the installation; the shell 1 is slidably connected to the bottom plate 12, and the bottom plate 12 can be easily installed and disassembled with the support of the sliding connection structure, while ensuring the tightness of the combination with the shell 1; the top of the bottom plate 12 A support plate 13 is fixedly connected to the support plate 13, which is used to provide structural support for the bottom plate 12 and provide a basis for the installation of the clamping block 15. A deformation groove 14 is opened inside the support plate 13. The deformation groove 14 can provide elastic buffering through appropriate deformation of the support plate 13 during the installation of the bottom plate 12, thereby reducing structural stress during the installation process and improving the flexibility and accuracy of the installation. A clamping block 15 is fixedly connected to one side of the support plate 13. The clamping block 15 is used to fit into the clamping groove 11, ensuring the close combination of the bottom plate 12 and the housing 1 through the fitting method. At the same time, the fitting of the clamping block 15 through the deformation groove 14 further enhances the stability and durability of the fitting.

[0041] Specifically, the mainboard 2 is precisely engaged and installed inside the shell 1 through the limit block 10, ensuring the stable position of the mainboard 2 in the shell 1 and avoiding any loosening caused by vibration or external force. When the bottom plate 12 is combined with the shell 1, the bottom plate 12 is precisely engaged with the slot 11 of the shell 1 through the block 15 on the side of the support plate 13 at its top, forming a firm connection. The block 15 is designed to produce a certain elastic deformation through the deformation groove 14 inside the support plate 13, so that the block 15 can be smoothly inserted into the slot 11. When the block 15 is fully embedded in the slot 11, the blocking structure in the slot 11 will limit the rebound of the block 15, ensuring a tight lock between the bottom plate 12 and the shell 1. This design not only facilitates the rapid assembly of the shell 1 and the bottom plate 12, but also improves the firmness of the connection part, making the entire device more stable after installation, avoiding structural looseness or poor contact caused by improper installation, thereby effectively enhancing the overall durability and stability of the equipment.

[0042] Working principle: When using the new fingerprint collection module, first, the double-sided wedge-shaped sealing ring 7 is embedded in the connecting groove 5 through the connecting ring 8, and at the same time, the shell 1 and the connecting ring 8 are embedded in the groove 9 through the convex ring 6 in the shell 1, so as to improve the sealing between the connecting ring 8 and the shell 1. Then, after the mainboard 2 is installed in the shell 1, the fingerprint module 4 extends from the shell 1, and the shell 1 and the fingerprint module 4 are sealed by the double-sided wedge-shaped sealing ring 7, thereby achieving the effect of improving the sealing. The mainboard 2 is snap-fitted and installed in the shell 1 through the limit block 10. Then, when the bottom plate 12 is combined with the shell 1, the bottom plate 12 is locked by embedding the block 15 on the side of the top support plate 13 into the card slot 11. The card block 15 can produce a certain deformation through the deformation groove 14 inside the support plate 13, so that the card block 15 is embedded in the card slot 11, thereby achieving the effect of facilitating the assembly of the shell 1 and the bottom plate 12.
