Embodiment Construction

[0023] figure 1 Among them, the high-intensity LED light source 11 emits visible light, which generates an image after passing through the liquid crystal light valve 12, and projects it onto the transflective display screen 14 through the mirror 13, and the reflected light is received by the human eye 15. At this time, the human eye observes The image seems to be suspended above the road. When the infrared night vision function is activated, the infrared LED light source (belonging to the pre-installed equipment) located at the headlights is turned on, and at the same time, the infrared imaging systems 17 and 18 collect infrared images, convert them into visible light images, and transmit them to the control device of the liquid crystal light valve , to project image information and night vision images onto the transflective screen. Among them, the transflective display screen is composed of a lens whose two surfaces are free-form surfaces. The mirror 13 can be finely adjust...

Abstract

Disclosed is an intelligent vehicle-mounted suspension type night-vision head-up display device. An optical projection component and an infrared imaging component are integrated and are mounted between an automobile inner rearview mirror and a front windshield, and a display screen is a semi-transparent semi-reflection screen with free curved surfaces on the front surface and the rear surface and is placed in front of a steering wheel. An active infrared detection mode is adopted, and an infrared LED light source of a vehicle lamp is utilized; an infrared image is obtained through an infrared lens and an uncooled infrared focal plane array detector, and after being converted into a visible light black-and-white image, the infrared image is projected to the semi-transparent semi-reflection display screen to be received by human eyes. A driver not only can see driving information of speed per hour, rotating speed, oil consumption, navigation and the like through the head-up display device, but also can see the infrared image, and driving safety is ensured. The suspension type night-vision head-up display device is convenient to mount, easy to maintain and capable of being widely applied to various vehicle types.

Description

technical field [0001] The patent of the invention belongs to automotive electronic products, and specifically relates to a suspended head-up display with infrared night vision function. Background technique [0002] The English of the head-up display is Head Up Display, generally abbreviated as HUD, which means "head-up display", and it can also be called "head-up display". It was developed because of the internal and external visual contradictions caused. Like the technology developed in many wars, the initial application of HUD was on fighter jets. The earliest aircraft equipped with HUD was the French Mirage fighter. This comprehensive optoelectronic display device consisting of electronic components, display components, controllers, and high-voltage power supplies can project information such as flight parameters, targeting attacks, and self-inspection in the form of images and characters to the front of the cockpit through optical components. Assemble on glass. [0...
