AI Technical Summary

Technical Problem

In the existing technology, frost and fog on car windows are difficult to remove effectively, and existing defrosting and defogging methods can affect the performance of optical components or cause lens blurring.

Method used

Design an optical element support assembly, including a support, optical elements, a blower mechanism, and a heating mechanism. The airflow direction of the blower mechanism is set at an angle to the optical path direction. The heating mechanism heats the air and blows it towards the image acquisition area. Combined with a temperature sensor, defrosting and defogging are controlled.

Benefits of technology

It improves defrosting and defogging efficiency, avoids water vapor blurring the lens and affecting optical performance, and ensures the shooting quality of optical components.

Abstract

The application relates to an optical element support assembly, a windshield glass assembly and a vehicle, which comprises a support, an optical element, a blowing mechanism and a heating mechanism. The support is arranged on the inner surface of the windshield glass. The optical element is arranged on the support, the optical element is opposite to an image acquisition area of the windshield glass, and the detection signal of the optical element can pass through the image acquisition area. The blowing mechanism is arranged on the support, the wind of the blowing mechanism blows towards the image acquisition area, and the wind path direction is arranged at an angle with the light path direction of the optical element. The heating mechanism is connected with the blowing mechanism. Since the wind path direction of the blowing mechanism is arranged at an angle with the light path direction of the detection signal of the optical element, that is, the blowing mechanism cannot blow towards the optical element, and the lens of the optical element is not contacted, on one hand, the defect that the lens is blurred by water vapor can be avoided, on the other hand, the adverse effect of the blowing on the image shooting performance of the optical element is small, and the shooting quality of the optical element is improved.
