Infrared image pick-up device used for new energy automobile night vision assistant system

Abstract

The invention relates to an infrared image pick-up device used for a new energy automobile night vision assistant system. The device comprises a main body and an infrared emission device. The main body is provided with a protection mechanism. The infrared emission device is internally provided with an infrared emission mechanism. The infrared emission mechanism comprises a first driving motor, a first driving shaft, a translation block, bar-type teeth, a driven gear, a rotating shaft, a first infrared lamp, a second infrared lamp, and a buffer block. The protection mechanism comprises a protection plate, a rotation unit, and two driving mechanisms. The infrared image pick-up device used for a new energy automobile night vision assistant system performs position switching on the first infrared lamp and the second infrared lamp through the infrared emission mechanism, so a driver can select different infrared irradiation according to road conditions, a display screen clearly displays a front road, and safe driving at night is realized. Not only that, the protection plate is covered on a lens through the protection mechanism, but also a CCD is prevented from being damaged caused by light irradiating the internal of the main body through the lens, and devices in the main body are effectively protected.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to an infrared camera device used for a night vision auxiliary system of a new energy vehicle. Background technique [0002] An infrared camera is actually a monitoring device that integrates a surveillance camera, a protective cover, an infrared lamp, and a power supply cooling unit. At present, the most commonly used infrared waterproof camera in monitoring engineering is active infrared, which emits infrared rays from LEDs. Using CCD or CMOS, you can feel the spectral characteristics of infrared light (that is, you can feel visible light and infrared light), and cooperate with infrared lights as "illumination source". "Come to night vision imaging. The market is dominated by infrared LEDs with emission wavelengths of 850nm and 940nm. Because infrared cameras can capture objects that cannot be observed by human eyes in a dark environment, infrared cameras are widely used in ni...

Problems solved by technology

[0003] In order to enable the infrared camera equipment to capture a wide enough range, many manufacturers or engineering companies usually try to expand the viewing angle of the infrared light as much as possible during the production of the equipment, so that there is more room for lens selection. If you choose a wide-angle lens, there will be no "flashlight". "Phenomenon, but in some occasions, if the angle of the infrared light is too large, it will affect the imaging effect of the equipment, such as tunnels, because of their narrow and long characteristics, if the infrared light emission angle is too large, the imaging near the edge It will be too bright, forming a "light curtain" phenomenon, but the center in the distance is invisible, only a white phenomenon, because the image cannot be clearly displayed at this time, so that the driver cannot clearly observe the road conditions in the distance, in this case it will be Greatly increase the probability of traffic accidents, not only that, but the existing infrared cameras lack corresponding protection devices. Causes excessive brightness and glare, which not only affects the display effect of the device, but also reduces the service life of the CCD inside the camera
