[0052] Tool 10 DETAILED DESCRIPTION

[0053] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0054] like Figures 5 to 9 As shown, the fingerprint recognition device of the embodiment of the present invention includes a fingerprint module 1, a decorative part 2, a cover plate 3 and a touch display module 4. The top surface of the decorative part 2 has a mounting groove 21, and the fingerprint module 1 is arranged in the mounting groove 21. The bottom of the mounting groove 21 has a through hole 22 that penetrates the decorative part 2. The fingerprint module 1 passes through the through hole 22 and extends to the bottom surface of the decorative part 2. The fingerprint module 1 is installed in the mounting groove 21, and the fingerprint module 1 passes through the through hole 22 to achieve electrical connection with the outside. When disassembling the fingerprint module 1, it is only necessary to use the tool 10 to pass through the through hole 22 from the bottom of the decorative part 2. The tool 10 will push the fingerprint module 1 out of the mounting groove 21. After being pushed out, it can be replaced and repaired without disassembling other components. The operation is simple, which greatly improves the maintenance efficiency. At the same time, the fingerprint module 1 can be repaired and replaced separately, saving costs.

[0055] The fingerprint recognition device further includes a cover plate 3 and a touch display module 4. The cover plate 3 is connected to the skirt 24 of the decorative member 2, the touch display module 4 is connected to the bottom of the cover plate 3, and the through hole 22 is exposed on the outer wall surface of the touch display module 4. When assembling the fingerprint recognition device, the cover plate 3 is installed and connected to the skirt 24 of the decorative member 2 from the top of the decorative member 2, and then the touch display module 4 is installed and connected to the bottom of the cover plate 3 from the bottom of the decorative member 2, and finally the fingerprint module 1 is installed and connected to the mounting groove 21 from the top of the decorative member 2. The through hole 22 is exposed on the outer wall surface of the touch display module 4, so that part of the structure of the fingerprint module 1 will extend out of the bottom surface of the decorative member 2 through the through hole 22, and when disassembling the fingerprint module 1, there is no need to disassemble the touch display module 4, and the fingerprint module 1 is directly pushed out of the mounting groove 21 through the through hole 22 using the tool 10 for replacement and repair.

[0056] The fingerprint module 1 may include a fingerprint chip 11, a flexible circuit board 12 and a reinforcing sheet 13 connected in sequence from top to bottom. The flexible circuit board 12 extends out of one side of the reinforcing sheet 13, and the flexible circuit board 12 passes through the through hole 22 and extends to the bottom surface of the decorative member 2. The reinforcing sheet 13 is located at the bottom layer of the fingerprint module 1. The flexible circuit board 12 extends out of the side wall of the reinforcing sheet 13 and passes through the through hole 22. The fingerprint module 1 is convenient to realize electrical connection with the outside through the flexible circuit board 12, and the structural strength is high. Among them, the fingerprint chip 11, the flexible circuit board 12 and the reinforcing sheet 13 can be connected by bonding.

[0057] The reinforcing sheet 13 may not completely cover the through hole 22. There is a passage space between the reinforcing sheet 13 and the through hole 22, and the flexible circuit board 12 extends out of the bottom surface of the decorative component 2 through the passage space. When disassembling the fingerprint module 1, the tool 10 passes through the through hole 22 and can abut against the reinforcing sheet 13 to avoid the force on the flexible circuit board 12 and damage to the flexible circuit board 12.

[0058] The outer wall surface of the reinforcing sheet 13 can also be aligned with the inner wall surface of the through hole 22. When the fingerprint module 1 is installed in the installation groove 21, the outer wall surface of the reinforcing sheet 13 is aligned with the inner wall surface of the through hole 22 to maximize the passage space of the through hole 22, which is convenient for the flexible circuit board 12 to pass through and the fingerprint module 1 to be disassembled.

[0059] The reinforcing sheet 13 may also have a perforation (not shown in the figure), which is connected to the through hole 22. The flexible circuit board 12 may extend out of the bottom surface of the decorative element 2 through the perforation and the through hole 22, and the perforation and the through hole 22 may correspond to each other.

[0060] The through hole 22 may be close to the end of the mounting groove 21. When the fingerprint module 1 is installed in the mounting groove 21, it is convenient for the flexible circuit board 12 to pass through the through hole 22, and it is convenient for the flexible circuit board 12 to be distributed in the fingerprint module 1. The through hole 22 may be in the shape of a strip.

[0061] The mounting groove 21 may have a convex step 23, the bottom of the convex step 23 is connected to the bottom of the mounting groove 21, the top of the convex step 23 is raised upward in the vertical direction, and the top of the convex step 23 is connected to the fingerprint module 1. The mounting groove 21 on the decorative member 2 is recessed downward from the top surface of the decorative member 2, and the convex step 23 can effectively increase the thickness of the decorative member 2, enhance the structural strength of the decorative member 2, and improve the stability and reliability of the fingerprint recognition device.

[0062] The reinforcing sheet 13 is attached to the bottom of the mounting groove 21, the outer edge of the fingerprint chip 11 extends out of the outer wall of the reinforcing sheet 13, and the bottom surface of the fingerprint chip 11 is connected to the top surface of the convex step 23. The reinforcing sheet 13 is located at the bottom layer of the fingerprint module 1 and is attached to the bottom of the mounting groove 21, and the extended part of the fingerprint chip 11 is connected to the top surface of the convex step 23, which effectively strengthens the connection strength between the fingerprint module 1 and the decorative part 2, and the connection is convenient. At the same time, through the connection between the reinforcing sheet 13 and the bottom of the mounting groove 21, and the extension part of the fingerprint chip 11 is connected to the convex step 23, the installation positioning accuracy is high. Among them, the reinforcing sheet 13 is a steel sheet.

[0063] The fingerprint chip 11 is bonded to the top surface of the convex step portion 23, and the installation and connection are convenient. The reinforcing sheet 13 and the bottom of the installation groove 21 can be attached without bonding, so that the fingerprint module 1 and the decorative element 2 can be easily installed and disassembled.

[0064] The convex step portion 23 continuously surrounds the installation groove 21 and is connected to the inner wall surface of the installation groove 21. The structural strength of the decorative element 2 is effectively enhanced, and the convex step portion 23 is easy to process and manufacture. The decorative element 2 is made of metal.

[0065] The embodiment of the present invention also discloses an electronic device, which includes the fingerprint recognition device as described above. When disassembling the fingerprint module 1, it is only necessary to use the tool 10 to pass through the through hole 22 from the bottom of the decorative part 2. The tool 10 can push out the fingerprint module 1 in the installation groove 21 through the through hole 22, so that there is no need to disassemble the touch display module 4, the operation is simple, and the maintenance efficiency is greatly improved. At the same time, the fingerprint module 1 can be repaired and replaced separately, saving costs.

[0066] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
