Put it briefly, an optical rearview mirror that the present invention relates to outside rear auto window, see, it comprises a prism and convex lens, in more detail, because the optical effect of butt double prismatic square, as refraction and inverted image, back mirror has not only increased the side-looking angle behind this optics, and no matter weather condition how, can also make the driver see the side rearward vision simultaneously and directly to rearward vision at operator's compartment.
Those people that are familiar with this industry know that the catadioptre of the usefulness that drives a car comprises two side-looking catadioptres and an indoor reflection mirror.The side-looking catadioptre is installed in the relative both sides of auto body, is applicable to watch the side visual field; And the indoor reflection mirror is installed in preceding top in the car, is applicable to and watches directly to rearward vision.Side-looking catadioptre and indoor reflection mirror have been arranged, and the driver can drive a car when seeing side-looking catadioptre and indoor reflection mirror safely, thereby avoids contingent traffic accident.
Yet the side-looking catadioptre commonly used that is placed on driver's sight line only provides about 20 ° side-looking angle, exists a driver dead angle beyond the invisible, and this just may cause traffic accident.When air-conditioning or heating arrangement, because the inside and outside heal differential in compartment can be coverd with steam on the vehicle window, this just hinders the driver to find out outside window in starting car.Especially, descending such as snow sky or the severe weather conditions of rainy day, the window of coveing with steam can become fuzzyyer; So under severe weather conditions, must open vehicle window when watching catadioptre.
On snow sky or the date of rainy day,, just can not distinguish the object except the light of rear window outside owing to cover with steam on the rear window.In the case, the driver has to move backward by estimation, so can not make automobile avoid the collision of another automobile of back.In addition, even in the fine date, move backward,, thereby may cause the accident because rear view mirror commonly used does not allow the driver to view the rear bumper of automobile.
Side-looking mirror design commonly used becomes by Che Nei driver to adjust its upper and lower, right or left angle, so even be subjected to slight impact, when for example closing entrance door, the angle of side-looking catadioptre can change.This just makes the driver adjust the angle of catadioptre repeatedly to keep required visual angle.
In the process of making great efforts minimizing side-looking catadioptre dead angle, convex lens can be installed on the side-looking catadioptre, or on the appropriate location of auto body, an additional reflector be installed.Yet these convex lens or additional catadioptre all can not be got rid of the problem that can not observe under the severe weather conditions.In addition, also have several to utilize amplifying lens or catadioptre to separate the scheme of above problem.Yet this amplifying lens and catadioptre the two not only make image be inverted, and also have unusual ratio of refraction, so it is long or the side-looking mirror size is excessive to utilize amplifying lens or catadioptre all can be accompanied by cylindrical shell length.Therefore, with amplifying lens or catadioptre, not only practicality is relatively poor, but also the increase expense.
Therefore, an object of the present invention is to provide an optical rearview mirror that can overcome the above problems, it use a butt double prismatic square and one to one side be the convex lens on plane.This optical rearview mirror has increased back angle and has removed the dead angle, makes the driver can view rear bumper, thus contingent accident when having avoided reversing.Even, can provide a good rearward vision to the driver descending such as snow sky or the severe weather conditions of rainy day.
Another object of the present invention provides an optical rearview mirror that uses light shield and scattering device, this device is placed on before the screen surfaces of a screen lens that has a plane, rotate this device and can improve the brightness that focuses on image on the minute surface, provide the special quality image to the driver.
In order to reach above purpose, the invention provides an optical rearview mirror that uses the butt double prismatic square, this prism is suitable for overcoming abnormal refraction rate, the image inversion of using optical element to cause and separates with image.In an example, optical rearview mirror comprises that the visual angle of the image that image multiplication lens that image that a butt double prismatic square that makes backsight image or side backsight picture inversion on each direction, one have reversed the butt double prismatic square reverses again and have reversed the image multiplication lens converts the conversion catadioptre at the visual angle that is suitable for driver observation to.Optical rearview mirror also comprises the screen lens of an image that demonstrates conversion catadioptre projection and the device of shielding and scattering light, improves the brightness that focuses on image on the screen lens, high quality image is provided.In another example, optical rearview mirror does not use the conversion catadioptre, and uses a pair of double prismatic square that is placed between butt double prismatic square and the image multiplication lens, it be applicable to from the picture transmission of butt double prismatic square to screen lens and do not change the visual angle.In optical rearview mirror of the present invention, each optical element, promptly butt double prismatic square, image multiplication lens, conversion catadioptre, pair of straight angle prism, screen lens and light shield and scattering device are to be placed in the leak free housing, are installed on the vehicle body.
