Specific embodiment
With reference to embodiment, the present invention will be described in detail, and embodiment is only the preferred embodiment of the present invention,
It is not limitation of the invention.
A kind of camera protection cover with high-wearing feature, including glass substrate, the first filming layer and the second plated film
Layer.
The glass substrate has visible area and the non-visible area around the visible area, and the visible area light transmission is used for
Imaging；The non-visible area is light tight；Ink layer is additionally provided in the non-visible area of the glass substrate, the ink layer is in institute
It states one surface of glass substrate and forms the non-visible area.By this set, stray light can be eliminated.
Wherein, the glass substrate is preferably strengthened glass.
The first filming layer is arranged in the visible area of the glass substrate；Second film plating layer is arranged on the glass
In the non-visible area of glass substrate.
The first filming layer and the second film plating layer are different multilayered structures, the first filming layer and the second film plating layer
In include DLC film layer.Specifically, the first filming layer includes the first DLC film layer, the first oxygen successively outward from glass substrate
SiClx layer, the first anti-fingerprint layer, the first DLC film layer, the first silicon oxide layer, the first anti-fingerprint layer thickness be respectively 2-
15nm、2-15nm、5-15nm。
Second film plating layer includes the first silicon nitride layer, the second silicon oxide layer, the second nitrogen successively outward from glass substrate
SiClx layer, the second DLC film layer, third silicon oxide layer, the second anti-fingerprint layer, first silicon nitride layer, the second silicon oxide layer,
Nitride silicon layer, the second DLC film layer, third silicon oxide layer, the second anti-fingerprint layer thickness be respectively 5-15nm, 20-50nm,
30-60nm、2-15nm、2-15nm、5-15nm。。
In the present invention, anti-fingerprint layer is included in the first filming layer and the second film plating layer, fingerprint can be cut down well
And various spot attachments, there is easy scrub clean, do not influence the appearance of protection cap.
Diamond-like is carbon-based（diamond-like carbon, DLC）It is that one kind contains diamond lattic structure（3 hydridization of sp
Key and graphite-structure（Sp2 hybrid bonds）Metastable amorphous state substance, carbon atom mainly with sp3 and sp2 hybrid bonds combine.DLC
