Abstract

The invention provides a fingerprint module assembly structure and a mobile terminal. The fingerprint module assembly structure comprises a fingerprint module and a fingerprint module assembly substrate. The fingerprint module comprises a fingerprint cover plate and a fingerprint chip from the up down in sequence. The cross section of the fingerprint cover plate is larger than that of the fingerprint chip; the fingerprint module assembly substrate is provided with an assembly hole; the assembly hole comprises a first accommodation portion for accommodating the fingerprint cover plate and a second accommodation portion for accommodating the fingerprint chip; the hole size of the first accommodation portion is larger than that of the second accommodation portion; and the first accommodation portion has a bearing surface for bearing the bottom surface of the fingerprint cover plate. The fingerprint module assembly structure can fix the fingerprint module without using a metal ring, and can realize connection and fixation of the fingerprint module and the fingerprint module assembly substrate through the bearing surface, thereby solving the problem of complex structure of an existing fingerprint module assembly structure.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a fingerprint module assembly structure and a mobile terminal. Background technique [0002] As a reliable identification method, fingerprint recognition technology will gradually become one of the necessary devices for mobile terminals or mobile payment terminals. At present, the fingerprint module is usually assembled with the touch screen glass of the mobile terminal, and its main assembly structure is a straight-through structure, that is, a hole is opened on the touch screen glass, and the fingerprint module is placed in the through hole as a whole. A metal ring for fixing the fingerprint module also needs to be set between the touch screen glass. It can be seen that there is a problem of complex structure in the existing fingerprint module assembly structure. Contents of the invention [0003] Embodiments of the present invention provide a fingerprint module assem...
