A self-cleaning starlight mirror glass film structure for vehicles and its preparation process

Abstract

The invention discloses a self-cleaning vehicular starlight scope glass film structure and a preparation technology thereof. The structure comprises a PE base film, wherein a plurality of groups of concentric annular lines are fixedly adhered to the upper surface of the PE base film; a silica gel adsorption pad is fixedly adhered to the lower surface of the PE base film; the thickness of the PE base film is gradually reduced from the inner side to the outer edge according to a sequence of the annular lines; the position where the thickness is reduced of the PE base film is polished and groundto form an arc shape; dust collection grooves are formed in the upper surface of the PE base film along two axes which are perpendicular to each other; the two dust collection grooves are intersectedat the circle center of the PE base film; a washing depression is formed in the circle center of the PE base film. The method comprises the steps of abrading and polishing the upper surface of the PEbase film to form the concentric annular lines, carving the dust collection grooves in the axes, and performing polishing mirror treatment on the whole structure, so as to obtain a finished product. The structure improves the field of vision through a convex structure, and improves the self-cleaning capability through the dust collection grooves and the washing depression.

Description

technical field [0001] The invention relates to the technical field of film sticking, in particular to a self-cleaning vehicle star light mirror glass film sticking structure and a preparation process thereof. Background technique [0002] With the development of automobile technology, the electronic equipment in the vehicle is also constantly updated, and as the very important lighting and monitoring equipment on the vehicle, it is very important. According to actual needs, most modern cars will be equipped with reversing audio and video, and in reversing audio and video, the most important thing is that the collected pixels are better, which can be said to meet the needs of different environments. [0003] However, in the actual reversing, the intensity of various ambient lights is inconsistent. In order to meet the light intensity requirements of the actual reversing audio and video, the reversing audio and video camera generally uses a starlight mirror. The high-pixel st...

Problems solved by technology

In the star light mirror, in order to overcome the environmental factors at the rear of the car and not affect the quality of the camera, it is necessary to clean the surface of the camera in time, but manual cleaning for a long time is a very tedious task, and it is often caused by neglect , resulting in unclear audio and video when reversing, and prone to traffic accidents

In particular, the existing lens field of view is small, and it is impossible to expand the field of view as much as possible under the premise of ensuring the quality of audio and video
