[0025] The utility model provides a fingerprint recognition module. Figures 1 to 3 This is a specific embodiment of a fingerprint recognition module provided by the present utility model.

[0026] like Figure 1As shown, the utility model embodiment provides a kind of fingerprint identification module 100, including hard circuit board 1 and fingerprint identification unit 2, the hard circuit board 1 has opposite first side and second side, the first side of the hard circuit board 1 has the connecting area that can be electrically connected with mainboard, the fingerprint identification unit 2 is electrically connected to the second side of the hard circuit board 1, the fingerprint identification unit 2 has the identification area for collecting fingerprint, the connecting area is electrically connected with the fingerprint identification unit 2 by the connecting hole on the hard circuit board 1.

[0027] In the utility model, the hard circuit board 1 has opposite first side and second side, the first side of the hard circuit board 1 has the connecting area that can be electrically connected with mainboard, the fingerprint identification unit 2 is electrically connected to the second side of the hard circuit board 1, the fingerprint identification unit 2 has the identification area for collecting fingerprint, the connecting area is electrically connected with the fingerprint identification unit 2 by the connecting hole on the hard circuit board 1. The connecting area and the fingerprint identification unit 2 are respectively arranged on the two sides of the hard circuit board 1 in the application, which greatly reduces the occupied area of the fingerprint identification module 100, and the hard circuit board 1 is used instead of the traditional flexible circuit board, without the need to set a support plate to provide support, thereby reducing the thickness of the fingerprint identification module 100. The fingerprint identification module 100 and the intelligent wearable device provided by the utility model solve the problem of large occupied area of the existing fingerprint module.

[0028] In order to improve the stability of the hard circuit board 1 and the mainboard connection, in some embodiments, as shown in Figure 1 As shown, the fingerprint identification module 100 further includes a connector 3 electrically connectable with the mainboard, and the connector 3 is arranged on the connecting area of the hard circuit board 1. In this way, the connector 3 is connected with the wires of the mainboard, so that the connection is more stable and the problem of poor contact is less likely to occur.

[0029] In order to reduce the thickness of the fingerprint identification module 100, in another embodiment, as shown in Figure 3 As shown, the connecting area is at least partially exposed copper to form a plurality of metal contacts 4 connectable with the mainboard. In this way, the plurality of metal contacts 4 are connected with the mainboard, without the need to install connecting components on the hard circuit board 1, greatly reducing the thickness of the fingerprint identification module 100.

[0030] In general fingerprint modules, since the connection area and the fingerprint recognition area are arranged on the same side of the circuit board, the area of ​​the circuit board is larger than the area of ​​the fingerprint unit. However, the present invention arranges the connection area and the recognition area on both sides of the rigid circuit board 1. The area of ​​the rigid circuit board 1 does not need to be larger than the area of ​​the fingerprint recognition unit 2. Therefore, in some embodiments, such as Figure 1 As shown, the area of ​​the rigid circuit board 1 is smaller than the area of ​​the fingerprint recognition unit 2. In this configuration, by reducing the area of ​​the rigid circuit board 1, the occupied area of ​​the fingerprint recognition module 100 is reduced.

[0031] In order to better fix the fingerprint recognition unit 2 on the rigid circuit board 1, in some embodiments, as shown in FIG. Figure 1 As shown, a chip filler 5 is filled between the fingerprint recognition unit 2 and the rigid circuit board 1. The chip filler 5 not only fixes the fingerprint recognition unit 2 and isolates the fingerprint recognition unit 2 from the external environment, preventing the fingerprint recognition unit 2 from being corroded by harmful substances such as moisture and oxygen, thereby improving the reliability and stability of the fingerprint recognition unit 2, but also protects the rigid circuit board 1 from mechanical stress and chemical corrosion.

[0032] To ensure a secure installation of the fingerprint recognition unit 2, in some embodiments, a glue reservoir for accommodating the chip filler 5 is provided on the second side of the rigid circuit board 1. The glue reservoir extends along the circumference of the rigid circuit board 1. This arrangement allows the chip filler 5 to be filled around the circumference of the rigid circuit board 1, thereby achieving a sealing effect.

[0033] In another embodiment, a plurality of glue dispensing areas are spaced apart along the circumference of the second side of the rigid circuit board 1. The operator dispenses glue only in the glue dispensing areas, without dispensing glue along the circumference of the rigid circuit board 1. This reduces the glue dispensing cost while ensuring the secure installation of the fingerprint recognition unit 2.

[0034] In some embodiments, the rigid circuit board 1 and the fingerprint recognition unit 2 are both arranged in a circular shape. On the one hand, it is more convenient to perform glue dispensing on the rigid circuit board 1, and on the other hand, the recognition area of ​​the fingerprint recognition unit 2 is more efficiently utilized.

[0035] Since the identification area of ​​the fingerprint identification unit 2 is exposed, it may be scratched during long-term use, affecting the collection and identification of fingerprints. Therefore, in some embodiments, Figure 2As shown, the recognition area of ​​the fingerprint recognition unit 2 is covered with a protective coating 6. On the one hand, the protective coating 6 can protect the recognition area of ​​the fingerprint recognition unit 2, and on the other hand, the color of the protective coating 6 can be adapted to the color of the housing of the fingerprint recognition device, thereby improving the integrity of the fingerprint recognition device.

[0036] In addition, the present invention also provides a smart wearable device, including a device body and the fingerprint recognition module 100, the fingerprint recognition module 100 is arranged on the device body, the device body includes a smart ring or a smart watch, the fingerprint recognition module 100 includes a hard circuit board 1 and a fingerprint recognition unit 2, the hard circuit board 1 has a first side and a second side relative to each other, the first side of the hard circuit board 1 has a connection area for electrical connection to the main board, the fingerprint recognition unit 2 is electrically connected to the second side of the hard circuit board 1, and the fingerprint recognition unit 2 has an identification area for collecting fingerprints.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
