The specific embodiment
For the ease of understanding the present invention, below with reference to relevant drawings, the present invention is described more fully.In accompanying drawing, provided better embodiment of the present invention.But the present invention can realize in many different forms, be not limited to embodiment described herein.On the contrary, providing the object of these embodiments is make the disclosure of the present invention understand more comprehensively thorough.
It should be noted that, when element is called as " being fixed on " another element, can directly can there is element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be directly connected to another element or may have centering elements simultaneously.Term as used herein " vertical ", " level ", " left side ", " right side " and similar statement just for illustrative purposes, do not represent it is unique embodiment.
Unless otherwise defined, all technology of using are herein identical with the implication that belongs to the common understanding of those skilled in the art of the present invention with scientific terminology.The term using in specification sheets of the present invention herein, just in order to describe the object of concrete embodiment, is not intended to be restriction the present invention.Term as used herein " and/or " comprise one or more relevant Listed Items arbitrarily with all combinations.
Refer to Fig. 1, the automobile prompt system 10 of the present embodiment, comprises automobile projecting lamp 100, Windshield 200 and the anti-knotmeter 300 that knocks into the back.Automobile projecting lamp 100 can be arranged on back seat near rear seat windscreen place, and Windshield 200 can be the rear seat windscreen of automobile, and automobile projecting lamp 100 can project corresponding information on Windshield 200, to point out front vehicle.
Concrete, seeing also Fig. 2 and Fig. 3, automobile projecting lamp 100 comprises light conducting cylinder 110, light source 120, liquid crystal display 130, crosses filter 140, lens 150, lamp housing 160, taillight 170 and Transparent Parts 180.
Light conducting cylinder 110 is the cylindrical shell of an end opening, offers the first corresponding through hole 161 on lamp housing 160, and light conducting cylinder 110 wears the first through hole 161, and part is contained in lamp housing 160.When this automobile projecting lamp 100 is during in control position, the opening of its light conducting cylinder 110 is over against the surface of Windshield 200.
Meanwhile, between light source 120 and liquid crystal display 130, lens 150 can be set, the light that lens 150 can be launched light source 120 is assembled.Specifically, at the present embodiment, lens 150 are two Fresnel Lenses that sphere arranges in opposite directions.
Automobile projecting lamp 100 also comprises controller 190, controller 190 is arranged on base plate 162, can control whole control automobile projecting lamp 100, as control on liquid crystal display 130 content showing, to change the information being finally presented on Windshield 200, or when this car brakes, open taillight 170, so that front vehicle is reminded, prevent to knock into the back.
See also Fig. 4, Windshield 200 comprises that the first photic zone 210, light-absorption layer 230 and the second photic zone 250, the first photic zones 210 and the second photic zone 250 that stack gradually make by transparent material, has good light transmission.Light-absorption layer 230 is made by light absorbent, the alternative light that absorbs specific wavelength.Light absorbent specifically can be MC photosensitive material, after absorbing the light of specific wavelength, and the colorific variation of MC photosensitive material meeting, but after losing the irradiation of this specific wavelength, it will be returned to color originally, also not affect normally passing through of daylight simultaneously.
When having the light of specific wavelength to project above-mentioned Windshield 200, light-absorption layer 230, by the light absorption of specific wavelength demonstration, forms corresponding information on Windshield 200.Light-absorption layer 230 only absorbs the light of specific wavelength, and general visible ray is as unaffected in daylight, car bulb etc., and occupant can observe the outer situation of car by this Windshield 200.
In order better to expand the indication range of Windshield 200, Windshield 200 can be curved glass, to expand the visible angle of the information demonstrating on Windshield 200.
The anti-knotmeter 300 that knocks into the back is arranged at vehicle tail, and for measuring in real time the speed of front vehicle, itself and automobile projecting lamp 100 communicate to connect, and by 100 pairs of rear-end collisions that likely occur of automobile projecting lamp, front vehicle are sent to early warning information.The anti-knotmeter 300 that knocks into the back comprises housing 310, probe 320 and processing module 330.Housing 310 is the cylindrical shell of an end opening.Probe 320 is infrared probe or laser probe, is contained in housing 310, and probe 320 infrared-rays that send or laser penetrate from the opening of housing 310, to measure in real time the distance between this car and front vehicle.
When the speed of front vehicle and this car is close, and distance keeps good, do not knock into the back dangerous time, the early warning information that controller 190 can generate by processing module 330 learns that current car travels safer.Now, controller 190 can be controlled liquid crystal display 130 and show advertising messages, and through the projection of automobile projecting lamp 100, advertisement is shown on Windshield 200 the most at last.Relative velocity between front vehicle and this car is too fast, occur knocking into the back dangerous time, controller 190 obtains the early warning information soon knocking into the back that processing module 330 is sent, and controls liquid crystal display 130, make to demonstrate on it corresponding warning content, and project on Windshield 200.Meanwhile, controller 190 also can be opened taillight, so that front vehicle is reminded.
Above-mentioned automobile prompt system 10, the light projecting by 200 pairs of automobile projecting lamps 100 of Windshield carries out selectivity absorption, shows corresponding prompting on Windshield 200, can remind to front vehicle the generation of Accident prevention.Windshield 200 only absorbs the light of specific wavelength, can not exert an influence to daylight or car bulb etc.And then can not affect occupant's the visual field, guaranteed the safety of travelling.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
