Problems solved by technology

[0006] In order to overcome the existing HUD products, the imaging position of the projected information is not located in the driver's main visual attention zone (PVAL area), which cannot meet the ergonomics characteristics, and causes the driver's sight to be distracted, and the display function is relatively simple, which cannot be based on The intensity of the external environment light adjusts the brightness of the displayed image and other deficiencies. The present invention provides a vehicle that satisfies the ergonomics characteristics so that the imaging position of the projected information is located in the driver's main visual attention zone (PVAL area) and can display multiple information. head-up display

Embodiment 1

[0030] refer to figure 2 and image 3 , a car head-up display device for multi-information display, including an image source screen 31 for displaying information, an embedded controller 4 and a control button 42 for controlling the image source screen 31, and the control button 42 is installed in the car The bottom of the instrument panel is characterized in that: it also includes a reflector group, an image correction lens 34 and an anti-reflection film 21, and the reflector group includes a plane mirror 32 and a non-planar reflector 33; the anti-reflection film 21 is attached to On the front windshield 2 of the automobile, the image source screen 31 is fixedly arranged below the plane mirror 32, the non-plane mirror 33 is arranged on the reflected light path of the plane mirror 32, and the image correction lens 34 is arranged on the plane mirror 32. directly above the non-planar mirror 33.

[0031] Further, the embedded controller 4 is fixedly installed directly below th...

Embodiment 2

[0045] In this embodiment, due to the limitation of the installation space in the vehicle, the image source screen 31 adopts a 4.3-inch TFT screen. The content of image source screen 31 is reflected on the non-planar reflector 33 by plane mirror 32, is reflected on the front windshield 2 that is attached with antireflection film 21 by non-planar reflector 33 again, utilizes non-planar reflector 33 to image content The magnification and the lengthening of the optical path are carried out, and through reasonable optical element design, the resulting virtual image 35 is finally positioned at an appropriate position in front of the driver's line of sight, so as to conform to the driver's visual characteristics when driving.

[0046] In this embodiment, the non-planar mirror 33 is in the form of a concave parabolic mirror. This involves the design and selection of the radius of curvature of the concave mirror 33 and the optical properties of the image correction lens 34. Due to th...

Abstract

The invention discloses a multi-information display head-up display device for an automobile. The multi-information display head-up display device for the automobile comprises an image source screen for displaying information, an embedded controller for controlling the image source screen and a control button. The control button is installed below an instrument panel of the automobile. The multi-information display head-up display device for the automobile further comprises a reflector set, an image correcting lens and an antireflection film. The reflector set comprises a plane mirror and a non-plane mirror. The antireflection film is attached to a front windshield of the automobile. The image source screen is fixedly arranged below the plane mirror. The non-plane mirror is arranged on a reflective light path of the plane mirror. The image correcting lens is arranged right above the non-plane mirror. The embedded controller is fixedly installed right below the image source screen and is connected with the image source screen through a wiring harness. The multi-information display head-up display device for the automobile further comprises a photosensitive sensor and a loudspeaker. The multi-information display head-up display device for the automobile provided by the invention not only considers characteristics of visual ergonomics, but also displays various information.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a vehicle head-up display device for multi-information display. Background technique [0002] Head Up Display (HUD) for vehicles is to use glass imaging to project the main information required by the driver in the form of icons or text in front of the field of vision, so that the driver can pay attention to the driving environment and related driving data at the same time. Avoid the distraction caused by the driver's line of sight deviation, and increase the safety of driving. [0003] Such as figure 1 As shown, the current common HUD product 1 generally adopts a simple one-time reflection structure with the front windshield 2 as the reflection surface in structure. Although this structure avoids relatively complicated optical system design, the imaging position 11 of the projected information is not enough Satisfying the ergonomic characteristics it should have, the...
