Description

Rear-view periscope mounted on the top of automobile

The utility model relates to a kind of automobile-used optical viewing arrangement, exactly, relates to a kind of backsight omniscope that is contained in car roof.

Automobile is the collection and the elite of human scientific and technological progress civilization, many scientific and technological achievements, and as vehicular telephone, high-power low oil consumption quiet motor, emergency braking and Unmanned Systems etc. has all entered in the people's activities shelter ┈ automobile.Along with the raising of car speed and the increase of function, the driver reaches situation on every side after needing to observe observation car further, to guarantee safe driving.But continue to use for these years for a long time, be installed in the rearview mirror of automobile cab dead ahead Windshield midway location usually, need just can observe automobile scenery in the wings by the automobile cab rear window; All the time do not make tangible improvement, the visual field that when rear window is blocked in loading behind carrying in the car or the car, just stops rearview mirror, this light deflector had just lost efficacy.The driver can't see situation behind the car clearly.For this reason, it is indoor that the applicant once designed a kind of vehicle drive that is loaded on, and the vehicle drive omniscope (patent No.: CN91203426.2) of ceiling is stretched out on its top.This omniscope is equipped with wide-angle lens, and the dioptric imaging visual field is broad, clear, lens barrel also lifting and left-right rotation flexibly, be convenient to observe behind the car and around scene.But because this device will be at the roof of the vehicle upper drill hole to stretch out the omniscope tube, only suitable car manufacturer adopts, and is not easy to user vehicle employing and popularization.

The purpose of this utility model provides a kind of needn't getting into the cave at roof of the vehicle, directly is placed on the backsight omniscope of car roof.

The utility model has kept original moulding of all kinds of automobiles fully, only places this device at its roof top, just can play scenery effect behind the good backsight observation car.It can be by retaining toward the visual field, and can keep whole advantages of above-mentioned last patent: afford a wide field of vision, imaging is clear, and is simple in structure, practical; Needn't destroy the original structure of automobile again.Warning lamp seat that can be on police car is adsorbed on the roof with permanent magnet during use; The time spent can not be easy to take off the original appearance of recovering automobile yet, and loading and unloading are convenient freely.

Fig. 1 is a scheme drawing of the present utility model.

Shown in Fig. 1, this device is made up of parts such as omniscope tube 1, rearview mirror 5, steer motor 6 and magnetic receivers 10, wherein omniscope tube 1 is by the horizontal lens barrel 1A that is loaded on roof with extend downward that refraction lens barrel 1B before the automobile cab window forms, wide-angle prism 2, convex lens 3 are housed in the rear end of horizontal lens barrel 1A, refraction light deflector 4 is housed in the junction of two lens barrel 1A, 1B, this refraction light deflector 4 can be a plane mirror, also can be prism.Rearview mirror 5 is equipped with in the lower end of refraction lens barrel 1B, and this mirror 5 is just facing to the front window 12 of automobile, and the driver observes scenery behind the car by other optical units on this backsight light deflector 5 and the light path thereof just in driving the way.Wide-angle prism 2 can be a bevelled mirror, also can be the block prism of forming with two bevelled mirrors, and it is to be contained in one to pay on the microscope base 9 that 7 transmission drives its rotation by steer motor 6, bevel gear.Steer motor 6 is by being contained in its rotation of push button control in the operator's compartment, can scanning tour to the car back spectacle thus.The base of omniscope is a permanent magnet seat 10, and whole device surrounds an integral body with casing 8.This device is firmly to be adsorbed on above the car roof 11 with permanent magnet seat 10, in case need also can take off easily when automobile disassembles; Here can use the such mechanism of similar machine industry magnet dial gage seat, bearing pin of push-and-pull and magnetic receiver is lost its reliss.The material of omniscope tube 1 of the present utility model and casing 8 can be aluminum alloy or engineering plastics.Wherein the horizontal lens barrel 1A of omniscope tube can make multiple different specification with the length of refraction lens barrel 1B with angle, to adapt to the different requirements that Different Kinds of Automobiles is installed and used.The shape of rearview mirror 5 also can be made variation, but is basical traditional model with the oblong, and its area is between 20～450 sq cms.After loading onto the utility model, originally the rearview mirror in the middle of the indoor front window of vehicle drive just can have been cancelled.

Claims (3)

1, a kind of backsight omniscope that is loaded on car roof, comprise the omniscope tube, rearview mirror, steer motor and magnetic receiver, it is characterized in that: omniscope tube 1 is by the horizontal lens barrel 1A that is loaded on roof and extend downward that refraction lens barrel 1B before the automobile cab window forms, in the rear end of horizontal lens barrel 1A wide-angle prism 2 is housed, convex lens 3, at two lens barrel 1A, refraction light deflector 4 is equipped with in the junction of 1B, rearview mirror 5 is equipped with in the lower end of refraction lens barrel 1B, wide-angle prism 2 is to be contained in one by steer motor 6, bevel gear is paid 7 transmission and is driven on the microscope base 9 of its rotation, the base of omniscope is a permanent magnet seat 10, and whole device surrounds an integral body with casing 8.

2, the backsight omniscope that is loaded on car roof according to claim 1 is characterized in that the refraction light deflector at the connection place of two lens barrel 1A, 1B dress, can be plane mirror, also can be prism.
