Fig. 2 is the display screen screen display mode schematic diagram of one embodiment of the invention.
Fig. 3 is the turning screen structure principle chart of one embodiment of the invention.
Fig. 4 is high intensity display screen structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the double mode head-up display device of one of the present invention is further described.
Double mode head-up display device of the present invention, as shown in Figure 1 and 2.For auto navigation and multimedia system, it mainly comprises
Projection module 100, for showing running information to user.
Gauge tap 200, the switch of control head-up display device and display mode etc.
Optical thin film 300, coordinates display running information when the present invention uses mirror projection pattern.
Concrete, projection module 100 comprises the display 110 that can realize projecting function and direct Presentation Function, and this display 110 is fixed on driver front.
In the present embodiment, be shown in Fig. 3 ~ 4, display 110 comprises hold-down support 111, overturning drive device 112 and high intensity display screen 113.Wherein, hold-down support 111 is fixed on the operation bench in driver's seat front, is detachable or is fixedly connected with operation bench.Overturning drive device 112 is arranged in hold-down support 111, and it comprises electro-motor 114 and gear set 115, and gear set drives the upset of 115 dynamic high intensity display screens 113.The trip shaft 116 for overturning is extended in high intensity display screen 113 both sides, is fixedly connected with gear set 115 near overturning drive device 112 side trip shaft 116.
Preferably, high intensity display screen 113 can realize 0 ~ 120 degree of upset of relative hold-down support 111 by overturning drive device 112.
In another embodiment, gear set 115 and hold-down support 111 extend a rotating shaft overturn for high intensity display screen 113 respectively to interior, the correspondence position of high intensity display screen 113 both sides is provided with mating holes 116 ', as shown in Figure 4 (b), make gear set that high intensity display screen 113 can be driven to overturn.
Preferably, high intensity display screen 113 high-high brightness is 3000 ~ 5000cd/m
2in one of them brightness.
Gauge tap 200 aspect, arranges on the steering wheel or is incorporated on operation bench, by the wherein a kind of connected mode connection control head-up display device 100 in bluetooth, wireless network, wired connection.Gauge tap 200 can control the unlatching of head-up display device 100, closedown, display mode switch and flip angle.
Further, optical thin film 300 is pasted on automobile windscreen inner, is oppositely arranged with projection module.
In another embodiment, can adjust by the flip angle of mode to high intensity display screen 113 manually.
In conjunction with the display packing of a kind of head-up display device of the present invention, when the present invention uses, gauge tap 200 is defaulted as projection mode after opening projection module 100, different display mode can be selected according to the different scene mode that is set in of automotive control system, send signal control projection module 100 when driving at night by gauge tap 200 and select mirror projection pattern, now can be in horizontality by highlighted display screen 113, and automatically image information is carried out mirror image switch, display backlight strength-enhanced to the first preset strength, i.e. higher backlight intensity, through the reflection of optical thin film, display meets the image of the reading habit of driver, coordinate other equipment of automobile, as infrared night vision detection, except running information, can also by the content projection that detects to driver front, driver will be caused dazzling and impact driving because of display brightness is too high again while auxiliary driving.And the brightness of image of projection pattern display is relatively low under the stronger environment of light on daytime, now by gauge tap 200, display mode is switched to display screen display mode, high intensity display screen 113 is in vertical state, and brightness is reduced to suitable degree, i.e. the second preset strength.Driver directly can carry out associative operation by the image information of watching high intensity display screen 113, plays energy-conservation effect.
Preferably, preset strength is a relative value, and system can carry out brightness fine setting according to actual environment light intensity.
Preferably, in high intensity display screen 113, establish the wherein one in gravity sensor, stroke detection switch or photoelectric detection switch, may according to the angle automatic switchover display mode of upset.With high intensity display screen and horizontal sextant angle be 45 ° for critical angle, when angle is large and critical angle time, the present invention uses display mode of display device; Mirror projection pattern is then used when angle is less than critical angle.In the process of driving, light may reflex to driver's eyes through display two, and impact is driven, and now can adjust flip angle to avoid the reflected light that impact is driven.And the position of mobile mirror when being shown by mirror projection pattern, also can be come by adjustment flip angle.
By reference to the accompanying drawings embodiments of the present invention are explained in detail above, but the present invention is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from present inventive concept.
