Abstract

The utility model relates to an optical device of periscope for automobile driving. A periscope which extends out of the automobile maps refracted erect image of the scene within 1000 meters of the outside of an automobile obtained by an optical circuit on a reflective rear view mirror in the automobile, which is convenient for the driver to observe the scene after the automobile and the scene around the automobile, and the driving safety is ensured. The optical circuit in the periscope comprises a wide-angle object glass, a field lens, a prism, an image rotation mirror, a prism, a wide-angle lens and a concave lens. The periscope for automobile driving is divided into an upper and a lower body structure and can be arbitrarily elevated and rotated without obstruction. The utility model has the advantages of large visual field, clear observation, simple structure, convenient operation and strong practicability.

Description

Periscope for automobile driving

The utility model relates to a kind of optical viewing arrangement, exactly, relates to a kind of indoor omniscope of looking around the outer scenery of car of vehicle drive that is contained in, and belongs to automobile-used backsight omniscope technical field.

Automobile is a product of concentrating human over one hundred year scientific and technological achievement, also is the collection and the elite of human progress civilization.Especially in recent years, various sophisticated technologies achievements, as vehicular telephone, high-power low oil consumption quiet motor, system controlled by computer emergency braking and Unmanned Systems or the like have moved in the shelter-automobile of the activity of packing into.So far still have thousands of scientists and engineers, automobile is all spared no effort to renovate from the appearance and modeling to the built-in function improve.But, be unexpectedly to have continued to use the rearview mirror that is installed in Windshield midway location place, the indoor dead ahead of vehicle drive usually for a long time, the most original for these years, but never make the great especially improvement of do all the time, so, as long as haulage truck is in a single day fully loaded with cargo, the visual field of blocking rearview mirror, this light deflector is just entirely ineffective, make the driver can't see scenery behind the car calmly clearly, feel inconvenience deeply.If run in the time of need monitoring special requirements such as whether the car tracking is arranged behind the car at any time, thinking also that present reflective back mirror uses very unsatisfactoryly complies with one's wishes.

The purpose of this utility model provide a kind of be used for vehicle drive indoor, be mainly used in backsight, also can be used for looking around the omniscope of the outer scenery of car.

The utility model is to utilize existing rearview mirror in the automobile, increases to join that an omniscope realizes again.This omniscope be by be the ┌ type, the operator's compartment ceiling is stretched out on its top, the last lens barrel that wide-angle lens, field lens, each a slice of isosceles prism and two image changing mirrors wherein are housed is nested in and is the ┘ type, the following lens barrel that isosceles prism, wide-angle lens and each a slice of concavees lens wherein are housed is formed, and the rearview mirror position is in the dead ahead that faces down lens barrel.

The utility model is a breakthrough to worried to destroy automobile streamlined appearance moulding and influenced the design philosophy obstacle of the speed of a motor vehicle in the past.In fact, all kinds of automobiles increase an omniscope that stretches out outside the operator's compartment ceiling can't influence its speed of a motor vehicle, and the various taxi sleeping carriages that " TAXI " sign is housed on the roof that runs quickly on the street now are illustrations.And, only can increase the elegance of all kinds of automobiles as long as the moulding of well-designed Sealing shield ring of the present utility model and omniscope tube is equipped with the harmonious spraying color of coordinating.After loading onto this device, chaufeur needn't be after vehicle window be observed car scenery, more can not be blocked the visual field, improve the visibility of observing, make driving safer.And the wide-angle lens dioptric imaging is housed in the omniscope, the visual field was more wide; The omniscope tube is lifting and left-right rotation flexibly, is convenient to observe at any time the outer scene all around of car and aims at required direction of observation.In a word, the present invention is simple in structure, and is easy to install easy, and very big practical value is arranged.

Below in conjunction with accompanying drawing, specifically introduce this device.

Fig. 1 is a structure diagram of the present utility model.

Fig. 2 is the site plan of the utility model in automobile.

Form by last lens barrel 10 and following lens barrel 11 two parts referring to Fig. 1 omniscope of the present utility model, last lens barrel 10 is the ┌ type, 4 two of wide-angle lens 1, field lens 2, isosceles prism 3 each a slice and image changing mirrors wherein are housed, and the installation site of each eyeglass is clamped by inner sleeve 12 location that last its inwall of lens barrel inner close fitting is equipped with.The outside of automobile cab ceiling 15 is stretched out on the top of last lens barrel, and the steel Sealing shield ring 13 of a hollow garden cylindricality is housed in its outside of stretching out the roof place, is equipped with in the middle of it and can prevents the globule into the car, does not influence the rubber oil sea 14 of lens barrel lifting rotation again.The bottom of last lens barrel then is nested in down in the vertical component of lens barrel, oscilaltion flexibly and comfortably and left rotation and right rotation, and clamp and locate the orientation that goes up lens barrel by the similar catch gear 8 that its lifting bar is located in adjustment as pedestal fan that is contained in down lens barrel 11 upper ends.This catch gear 8 can be the screw-type tight locking button, also can be pin cam-type clamping mechanism.11 of following lens barrels that are the ┘ type are by chrome bracket 17 supporting location, and the upper end of this carriage is packed on the operator's compartment ceiling 15.Also isosceles prism 5, wide-angle lens 6 and concavees lens 7 each a slice have been clamped in the following lens barrel with inner sleeve 12 location.16 positions of the rearview mirror that originally was equipped with in the car are in the dead ahead that faces down lens barrel 11.Like this, just formed the principle of using omniscope, form the light path of looking in the distance and diving and hoping by wide-angle lens, field lens, prism, image changing mirror, prism, wide-angle lens and concavees lens, can the scenery in outside the car 1000 meters be reflected just as on the reflective back mirror that is mapped in the automobile.And, because last lens barrel is nested in down in the lens barrel, can be flexible, lifting is rotated easily, is not subjected to blocking of operator's compartment rear side goods or people, sees behind the car scenery clearly or looks around view on every side.The visual anti-area size of looking back mirror of lens barrel clear aperture of the present utility model is determined; Its height that stretches out the operator's compartment top is then determined by its clear aperture.Usually clear aperture is big, and extended roof is shorter; If clear aperture is little, then extended roof is high.Lens barrel can be made by the plastic-blasting steel, and various eyeglasses are optical glass lens, and diameter is between 2～4 centimetres, observes visibility to improve.

Fig. 2 is the position view of this device in automobile.20 is reflective back mirror among the figure, and 21 is omniscope.22 is automobile.
