Autonomous demisting type vehicle-mounted camera

Abstract

The invention discloses an autonomous demisting type vehicle-mounted camera, and belongs to the technical field of vehicle-mounted cameras. A demisting ring sleeve is embedded in the front end of a lens of a camera body, a plurality of adsorption pipes extending to the inner side of an annular heating cavity are annularly distributed on the side wall of the demisting ring sleeve, moisture absorption fiber cotton is embedded in the adsorption pipes, when water mist and water drops exist in front of the lens, the moisture absorption fiber cotton adsorbs moisture, a humidity sensor located on the inner side of the annular heating cavity detects the humidity change of the moisture absorption fiber cotton and transmits a signal to heating wires and a ventilation mechanism, the multiple heating wires start heating, the temperature in the annular heating cavity rises, a temperature sensing deformation body bends and shrinks due to the high temperature, the moisture absorption fiber cotton is pulled to move towards the inner side of the annular heating cavity, the outer ends of the adsorption pipes are exposed, at the moment, air is supplied to the annular heating cavity through an air exchange mechanism, the heated air overflows outwards through a plurality of ventilation holes, water mist and water drops in front of the lens are dried, and autonomous intelligent demisting is completed.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted cameras, and more specifically, relates to an autonomous defogging type vehicle-mounted camera. Background technique [0002] With the development of ADAS (Advanced Driver Assistance System) functions, car cameras are becoming more and more common and are receiving more and more attention. Car cameras are used in many ways, not only in traffic video recording, but also in safe driving. For example, the popular reversing camera function is one of the safety configurations of modern cars. [0003] However, car cameras are generally installed on the outside of the car. When it rains in summer, there will be water droplets or fog on the reversing camera. When it snows or frosts in winter, problems such as frost will appear on the reversing camera, or from a low temperature environment to a high temperature environment. , will also cause water mist to appear on the camera. Therefore, the info...

Problems solved by technology

[0003] However, car cameras are generally installed on the outside of the car. When it rains in summer, there will be water droplets or fog on the reversing camera. When it snows or frosts in winter, problems such as frost will appear on the reversing camera, or from a low temperature environment to a high temperature environment. , will also cause water mist to appear on the camera

Therefore, the information outside the vehicle cannot be obtained in real time, seriously affecting the use of the camera, and resulting in a low driving safety factor
