Background technology

Along with expanding economy, people's living standard is improved, people more and more are particular about quality of the life, Science & Technology Demands to automobile also further strengthens, therefore, on the console of automobile, need the information shown to get more and more, such as air-conditioning information, navigation information, audio-visual entertainment information, motoring condition information etc., generally need to bow and watch the read out instrument be positioned on console when chaufeur is watched these information, therefore eyes can leave the direction of visual lines of running car, if vehicle is under high-speed travel state, the time of seeing read out instrument even bow is 0.5 second, vehicle also nearly travels more than 10 meter so, as run into the reaction time that emergency case has reduced chaufeur, not only allow chaufeur feel inconvenience, also reduced the safety while driving simultaneously.

On the other hand, HUD is the abbreviation of head-up display, generally be used at present the flight assistive device of aerospace field, the HUD technology generally adopts the projection electronic machine, the information that some need be shown directly projects to the on glass of chaufeur the place ahead, this technology has realized that chaufeur does not need to bow and just can see his needed important information, having reduced chaufeur need to bow and check the frequency of instrument, but the sight line of chaufeur need not be from travel direction with regard to the direct viewing relevant information like this, avoid interrupting reducing because of the chaufeur attention safety factor of driving, greatly improved the safety of driving.

The utility model content

There are the problems referred to above in the utility model for existing technology, a kind of windshield projection arrangement of looking squarely Presentation Function that has is provided, this device can be projected in video, image and the Word message of vehicle electronic device output on the film of windshield, thereby solved because of the chaufeur potential safety hazard that the information of checking produces of bowing, for user's routine safety brings very big facility with car.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of have a windshield projection arrangement of looking squarely Presentation Function, and by being arranged on the film that automobile windscreen inner is transparent and being placed in car body inside, and the projection arrangement that information is projected on this film forms.

Specifically, described projection arrangement comprises signal processing module and projector, the vehicle electronic device of described signal processing module and car body inside communicates by the mode of wire harness or radio communication, described signal processing module carries out video, image and the Word message of vehicle electronic device output to flow to described projector after analyzing and processing, controls described projector information is projected on the film that is arranged on automobile windscreen inner.

As preferred version, described projector is fixed on the interior roof of operator's seat of vehicle by support.

In another preferred version, described projector is fixed on the vehicular drive platform.

Further, described windshield comprises shield glass and side windshield of automobile, and as preferred version, described film is pasted or is plated on the front windshield inner surface.

Preferably, the size of described film is equal to or less than the Windshield size.

Preferably, described projector is miniature laser projector or infrared projector.

The beneficial effects of the utility model are:

In the utility model, projector can directly be incident upon the demonstration information of vehicle electronic device output on the film of Windshield, such as: audio-visual entertainment information, driving and vehicle condition information etc., can make chaufeur bow and just can see these information, and film is transparent, it does not affect the light transmission of windshield itself, does not affect driving sight, for user's routine safety brings very big facility with car.

The accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
