Description

Technical Field

[0001] The utility model relates to the technical field of control boxes, in particular to a control box uniformity jig. Background Art

[0002] At present, when the driver is driving at night, there is a car driving behind, and the headlights of the existing car control box shine on the rearview mirror. The strong light will shine on the driver's eyes and cause glare, and the driver's eyes will be dark in an instant. At this time, if there are vehicles or pedestrians in front, it will easily cause traffic accidents. The principle of anti-glare for rearview mirrors is that when strong light shines on the rearview mirror, the sensor on the mirror sends the light signal to the microcomputer. After signal processing, the control circuit will change the color of the mirror to absorb the strong light and reduce the reflection of the strong light. The fundamental principle of controlling the uniformity of the EC material that absorbs light intensity in the rearview mirror is to control the uniformity of the box thickness, so ensuring the uniformity of the thickness of the prepared device box is of utmost importance. Therefore, a control box uniformity jig is designed to ensure the uniformity of the thickness of the prepared device box. Utility Model Content
