Abstract
The utility model relates to a viewing device of side and all vision for an automobile which belongs to an optical instrument, comprising a wide-angle image picking mirror (1), a magnifying mirror (2), a reflecting mirror (3) and a machine body (4). The utility model can eliminate the blind spot of side view zone of the automobile to provide a driver with the complete viewing objects at the side of the vehicle body. With the advantage of easy installation, the utility model can avoid the accidents of personal casualty and vehicle damage and ensure traffic safety after being used by vehicles.
Description
The utility model is a kind of for the driver's observation vehicle body side, the all-around visibility optics instrument of especially near vehicle body side Zone Full.
Existing vehicle all is equipped with the side direction back mirror, reflect to chaufeur by the scenery of curved reflector vehicular sideview, so that chaufeur takes effective measures, but the actual observation ability that is limited to object minute surface and human eye, catadioptre can only be with i.e. 25 °-40 ° the scope imaging (as Fig. 1) of vision area behind the side of car body, and remaining scope will become the dead angle area in the visual field, overtaking other vehicles, give another the right of way, bringing many inconvenience to chaufeur in reversing or the driving process, be unfavorable for safety traffic.
For the whole vision areas that make chaufeur can in time observe vehicle body side under various travel situations are eliminated the blind area district, so that make right judgement, guarantee safety traffic, the utility model provides a kind of side to look finder entirely.
This installs by following component set-up:
1, wide-angle picks up and resembles mirror, and it is made up of two concavees lens, can be 100 °-150 ° with ball angle, garden, space, and the best is that 120 ° scope is carried out imaging; Diameter is 110-150mm, and the best is 120mm.
2, eye gauge, the employing focal length is 8-12.5cm, coefficient of amplification is a 2-3 ordinary lens doubly.
3, the counter-rotating mirror can be plane mirror, spherical reflector, also can be completely reflecting mirror, size: bore is long to be 110-150mm, and bore is wide be 150-220, with length be 120mm wide for 170mm be the best.
4, body is made of edge mirror shell and supporting base, and material therefor is: various eyeglasses all adopt optical glass or transparent photon plastics, and body adopts common rigid PVC.
The principle of work of this device is: incident ray by wide-angle pick up resemble mirror after, enter eye gauge, light be exaggerated and by catadioptre with 90 ° of light counter-rotatings after, enter the eyes of chaufeur.Wherein each functions of components is as follows:
Wide-angle picks up and resembles mirror (1): the scenery of space angle in 120 ° of-140 ° of scopes all can be taken in, and can be adjusted between ± 0-15 °;
Eye gauge (2): the image of taking in is carried out processing and amplifying, for chaufeur provides car body side direction video correct, true to nature;
Counter-rotating mirror (3): available 90 ° total reflection prism, with 90 ° of the counter-rotatings of the light after amplifying, to chaufeur provide just as, and this catadioptre can rotate 360 ° around axial line, to enlarge the observation visual field of chaufeur.Also can constitute in addition by plane mirror or spherical reflector;
Body (4): this device can be installed on the automobile by body (4), in addition, because the effect of body can make optical element be fixed on the corresponding working position and also can regulate within the specific limits.
Fig. 1 is existing automotive visibility distribution schematic diagram.
Fig. 2 is this device of automotive use rearward vision distribution schematic diagram.
Fig. 3 is structure diagram of the present utility model (an A type).
Fig. 4 is structure diagram of the present utility model (Type B).
Among the figure: (1) is that wide-angle picks up and resembles mirror, and (2) are eye gaugees, and (3) are the counter-rotating mirrors, and (4) are bodies.
Because the utility model can be eliminated dead angle, automobile side-looking district, make chaufeur can observe whole visual fields situation of vehicle body side, no matter be to overtake other vehicles, give another the right of way, moveing backward or in the process of moving, all can on-the-spot in hand truth, take favourable measure, guarantee the safety traffic of automobile.Embodiment:
Selecting wide-angle to pick up to resemble the material of mirror, eye gauge, catadioptre is optical glass.
Wide-angle picks up and resembles mirror and combined by two concavees lens, but ball angle, intake space garden is 120 ° a scenery, and diameter is 120mm.
The focal length of eye gauge is 100mm, and magnification factor is 1.5 times, and diameter is 120mm.
The catadioptre bore is long to be 120mm, and wide is 170mm, and the angle α between incident ray and the refracted ray is 90 °, and angle of field 2W is 120 °.
