Heated Anti-fog lens structure

Abstract

This invention provides a waterproof and defogging lens structure, comprising a lens barrel body, a lens assembly, a temperature sensing module, a heating element module, and a heat-insulating and waterproof adhesive. The lens assembly, disposed within the lens barrel body, includes at least one lens element. The temperature sensing module, also disposed within the lens barrel body, is configured to directly sense the temperature of the metal lens barrel body. The heating element module includes a heating ring and a flexible flat cable connecting the heating ring and extending outside the lens barrel, disposed within the lens barrel body to provide a heat source for defogging. The heat-insulating and waterproof adhesive, disposed within the lens barrel body, is configured to fix the heating element module and the temperature sensing module, and provides a protective layer for the flexible flat cable. With this structural design, this invention can detect the lens barrel temperature to drive heating in a timely manner to improve fogging, while also providing waterproofing, heat insulation, and circuit protection for internal components.

Claims
