In order to make the objects, technical solutions and advantages of the present invention clearer, the following will describe in detail an implementation method of the present invention with reference to the accompanying drawings and embodiments, so that how to apply technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented.
With the rise of mobile electronic products, people have higher requirements on the experience of mobile phones, and more functional coating cover plates are derived. Existing cover plate coatings may generally include a reinforcement layer that may be disposed directly on the cover plate as a surface-enhancing coating, however, for glass cover plates, because the reinforcement layer is typically made of carbon allotrope materials, compatibility with glass cover plates formed of siloxane-based materials is poor, resulting in poor adhesion of the reinforcement layer disposed directly on the glass cover plate and poor stability of the reinforcement layer. In addition, for the flexible cover plate, the adhesion between the reinforcing layer and the cover plate is easily deteriorated due to the multiple bending during the use process, which also results in poor stability of the reinforcing layer directly disposed on the cover plate.
In view of this, the present invention provides a cover plate structure, which may include a cover plate body, a connection layer, and a reinforcement layer stacked on the connection layer, where the reinforcement layer covers at least a portion of an upper surface of the connection layer, the reinforcement layer is connected to the cover plate body through the connection layer, and the upper surface is a side surface of the connection layer away from the cover plate body. Through set up the articulamentum between enhancement layer and apron body, can effectively strengthen the adhesion between enhancement layer and the apron body, improve the stability of enhancement layer.

In the embodiment of the present application, the adhesion between the connection layer 11 and the cap body 10 is greater than the adhesion between the reinforcement layer 12 and the cap body 10.
