Embodiment 1

[0044] see Figure 1-7 , a self-defogging vehicle-mounted camera, comprising a camera body 1, the front end of the lens of the camera body 1 is fixedly connected with a defogging ring sleeve 2, and the rear end of the defogging ring sleeve 2 is provided with a matching embedded wall of the camera body 1 Arc-shaped cavity, the front end of the defogging ring sleeve 2 is provided with an annular heating chamber 201, and a plurality of adsorption tubes 4 are distributed on the inner wall of the defogging ring sleeve 2, and the inner ends of the plurality of adsorption tubes 4 extend to the ring heating chamber. The chamber 201 communicates with the annular heating chamber 201 . The outer ends of the plurality of adsorption tubes 4 are exposed at the front end of the lens, and the interiors of the plurality of adsorption tubes 4 are movably embedded with hygroscopic fiber cotton 10 .

[0045] see Figure 6-9 Among them, a group of symmetrically arranged adsorption tubes 4 is embe...

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...
