Description

Composite board structure, battery cover and mobile terminal

Technical Field

The utility model relates to a mobile terminal technical field, in particular to composite board structure, battery cover and mobile terminal.

Background

The battery cover (back cover) of the mobile terminal generally adopts a plastic, metal, composite plate structure, or high-strength glass structure.

With the increasing requirements of users on the texture of the mobile terminal, the battery cover adopting the glass structure becomes the mainstream. However, the process cost of the glass battery cover is high, and the glass battery cover is generally used for high-end machines. Although the plastic composite board can have the appearance effect similar to that of glass, the transparent texture of the glass is difficult to achieve completely; the color is bright, the temporary realization of strong stereoscopic impression can not be realized, and the color effect of low end can only be realized.

In order to realize the appearance effect of glass, at present, the realization is through several kinds of modes, one kind is that the thickness that increases the rendition glue promotes colour feel, the thickness of general rendition glue is 10+2um, if it needs to reach 18 ~ 25um to promote thickness, it is very high to glue tensile strength and pliability requirement, current glue in the industry can not do so thick yet, the glue principal ingredients is the resin, can harden after the UV solidification, become fragile, thicker thin thickness can make product overall structure more fragile, can cause the problem that the complete machine falls to test the fracture. The other is to increase the thickness of the transfer glue to improve the color texture, and the thickness of the common transfer glue is 10+2 um; if the lifting thickness needs to reach 18-25 um; the requirement on the tensile resistance and the flexibility of the glue is very high, the glue in the prior art cannot be made thick, the main component of the glue is resin, the glue becomes hard and brittle after UV curing, and the thicker thickness can make the integral structure of the product more brittle, so that the problem of cracking of the whole machine in a drop test can be caused.
