Abstract
The utility model discloses a front-rear view arrangement for vehicle which belongs to the technological improvement of the vehicle accessory. The device keeps the function of the original rear viewing mirror of the vehicle and is simultaneously added with the function which is used to know the real-time information of the forward vehicle, the pedestrian and the road to improve the driving condition and achieve the purpose of safe driving. The device uses the original rear viewing mirror of the vehicle and is provided with a front viewing mirror and a plane mirror to complete the reversing process. The device is provided with a distance viewer which can estimate the distance of the forward vehicle, the pedestrian and the barricade. The utility model has the advantages of simple device, low cost and easy production. The front-rear view arrangement for vehicle is suitable to be used for all the vehicles in particular to the medium and minitype cars.
Description
The utility model belongs to the technological improvement of motor vehicle fittings.
At present, can understand the car rear by back mirror in the motor-driven vehicle going process and trail or cut-in situation, to take the driving measure to vehicle.But in the driving process, often must understand forward direction vehicle or road conditions, in overtaking process, particularly important especially.According to the statistics made by the departments concerned, the accident of overtaking other vehicles and causing owing to mal, in traffic accident, occupy larger proportion, and the accident grade malignancy is bigger, analyzes its reason, and mainly being can not provide car forward direction situation because of original back mirror, the sight line of navigating mate is hindered by front vehicles, do not see forward direction vehicle and road conditions, due to blindly overtaking other vehicles, centering dilly problem is particularly outstanding.Be to understand the forward direction situation, navigating mate is got used to the frequent swing upper body, or leans to one side that head is stretched to operator's compartment and drive towards in the middle of the road outside window or with car, and again do not meet forward direction and head-on send a car as road is very broad this moment, and these behaviors all may cause the generation of grave accident.Sometimes, also because of can not overtake other vehicles several times, cause the rashness of navigating mate easily and influence safe driving.
Task of the present utility model is that the original back mirror of self-propelled vehicle is done technological improvement, and a kind of self-propelled vehicle front and back view apparatus of practicality is provided.
The scheme that solves be in back mirror to several optical elements of dress, in order to the real time information of transfer machine motor-car forward direction vehicle and road, And is furnished with range finder, can roughly estimate to send a car with forward direction and the distance of pedestrian or roadblock.
View apparatus before and after the utility model self-propelled vehicle, except simple in structure, easily manufactured, cost is low, easy to use, significantly advantage is when keeping original backsight effect, actv. improves the navigating mate forward direction visual field (as accompanying drawing 1), grasp the forward direction trend better, thereby reduce or eliminate the improper behavior of overtaking other vehicles substantially, stablize the mood of navigating mate.Another benefit is that navigating mate need not the frequent swing upper body or head is stretched to operator's compartment outside window, also need not vehicle is driven towards in the middle of the road, thereby also can prevent the generation of contingency.
Fig. 1 is a view apparatus result of use scheme drawing before and after the self-propelled vehicle, among the figure: view apparatus H-navigating mate before and after the A-forward direction the other side B-forward direction vehicle of sending a car, C-passing vehicle D-.Dotted line is the visual field of navigating mate when not using the front and back view apparatus, and solid line is the visual field of navigating mate when using the front and back view apparatus.
Fig. 2 is front and back view apparatus cutaway views.Wherein: 1-forward sight convex mirror 2-backsight convex mirror 3-forward sight plane mirror 4-sighting distance plate 5-framework 6-active joint 7-liner plate.
Below in conjunction with the embodiment accompanying drawing, the utility model is described in further detail.
Backsight convex mirror (2) has identical effect with common automobile rearview, i.e. understand the back in the driving process and trail, watch the back to situation when cut-in situation or reversing to vehicle.Forward direction vehicle, pedestrian and road conditions are resembled through forward plane mirror (3) commentaries on classics by forward direction convex mirror (1) imaging, enter the navigating mate organs of vision, and navigating mate is made the driving measure thus.At the preceding range finder of being furnished with the band stadia rod of forward direction convex mirror (1), be used for estimating the distance of forward direction vehicle, pedestrian and roadblock etc. and car, range finder is a sighting distance plate (4) in the present embodiment, it adopts the plate glass that thickness is even, colourless, diaphaneity is high, ratio of refraction is consistent, and stadia rod designs and produces by common optical range principle and lithographic method.
In the present embodiment, above-mentioned each member is the outward appearance that is rectangle of the same size.Sighting distance plate (4) directly is fixed on the framework (5), all the other all are fixed on the liner plate of making of High molecular material (or metal) (7); And is connected with framework (5) separately by the movable section header (6) of general spherical shape structure, and each member can be adjusted the position at any time on demand.The recess and the liner plate (7) of movable section header (6) are used the high-quality plastics injection mo(u)lding, and the bolt of the spheroid of embedding and an end is made with the chromium plating of common charcoal steel.Forward direction convex mirror (1), back to convex mirror (2) and forward plane mirror (4) be with thickness 2 millimeters even, colourless, diaphaneity Gao And ratio of refraction unanimity glass and adopt the mirror-making material and the technology of routine, make as glass coated silver or aluminium lamination.Framework (4) highstrenghtpiston's injection moulding or the compression molding of bakelite material, framework (4) roughly is installed in the former installation position of rear view mirror of self-propelled vehicle.
This front-rear view arrangement for vehicles is applicable to all motor vehicles, especially is suitable for medium and small all kinds of automobiles.
