Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
The existing design mode on the market of the mobile phone fingerprint module is generally a reverse-loading mode, as shown in fig. 1, since the reinforced steel plate and the fingerprint functional sheet are integrated during production, the fingerprint module can only extend the fingerprint functional sheet from the bottom of the decorative ring and then fix the fingerprint functional sheet in the decorative ring during assembly, and when the reverse-loading type fingerprint module is applied to a mobile phone, the touch failure is caused because the fall of the fingerprint functional sheet and the decorative ring is large, and the touch feeling is poor and the touch failure is easy to be caused.
The inventor finds that if the thickness of the reinforced steel plate at the bottom of the fingerprint functional sheet is increased to raise the fingerprint functional sheet so as to reduce the drop, the cost of the fingerprint module is extremely high;
if the size of the reinforced steel plate in the horizontal direction is reduced to increase the thickness of the reinforced steel plate, and then the reinforced steel plate is placed into the decorative ring to make up the drop between the fingerprint functional sheet and the top of the decorative ring, because the outer diameter of the reinforced steel plate is smaller than that of the decorative ring, the reinforced steel plate cannot support the decorative ring, the reinforced steel plate falls from the decorative ring and cannot form a whole, so that the side edge of the reinforced steel plate needs to be fixedly connected with the inner side of the decorative ring through back glue, the fingerprint module part is tiny, the phenomenon of glue overflow easily occurs when the reinforced steel plate and the inner side of the decorative ring are back glued in the process, and the mobile phone is easy to generate heat when in use, and the back glue of the reinforced steel plate and the decorative ring is possibly degummed, so that the fixing mode is not firm and easy to damage.
The present invention therefore proposes the following embodiments to solve the above-mentioned technical problems.
