Description

A kind of automobile backsight device

Technical field

The utility model relates to a kind of automobile backsight device, belongs to the vehicular optical finder, Patent classificating number: B60R 1/00.

Background technology

Rear-view mirror device on the automobile is forward position, the chaufeur crown outside car left side, right side Windshield and in car at present, a reflective visor is installed, chaufeur is by to the observation of image information in the reflective visor, judges situation behind the car, decides the mode of driving.There are some problems in this automobile backsight device.As:

(1) owing to the installation site, chaufeur has the vision blind area, observes, is difficult to judge for the left and right inconvenience of overtaking other vehicles, and traffic accident takes place easily.

(2) left and right, back mirror is far away apart from chaufeur, and chaufeur needs continuous rotation head to observe, and therefore, influences the attention in driver's observation the place ahead, causes rear-end collision easily.

(3) less because of the sight glass area, the situation that left and right back mirror is observed is unintelligible, can not form the visual effect of whole observation.

(4) run into wind, rain, snow, greasy weather gas, or tie mist, ponding, freeze because of vehicle window, chaufeur can't see through vehicle window and observe, and influence is driven.

(5) reflective visor is contained in the car body outside, cause easily and unpowered vehicle, pedestrian between scratch, also occupied valuable garage space simultaneously.

(6) be installed in the reflective visor on the chaufeur crown in the car, be subjected to blocking of back row occupant or object easily, can not observe the situation behind the car, influence is driven, and especially high capacity waggon is all the more so.

Above-mentioned shortcoming, incompatibility modernized society transport development demand.People press for a kind of appearance that can overcome the new automobile backsight device of above-mentioned shortcoming, substitute the above-mentioned automobile backsight device of having used decades that prolonged, to guarantee traffic safety.

Summary of the invention

The purpose of this utility model is to provide a kind of automobile backsight device, this installs the rear-view mirror device of alternative used reflective visor, there is not the blind area, the driver's observation vehicle condition is convenient, light, can form the whole observation effect, and reduce occupation space outside car, be that a kind of chaufeur that helps improves traffic safety, later-model automobile backsight device.

The technical solution of the utility model is: a kind of automobile backsight device is characterized in that this device is assembled by circuit by three cameras and several electronic displays and automobile power source; Wherein two cameras are installed in respectively near the front truck headlight upper position of automobile left and right side, aim at the scenery of automotive back side; Another camera is installed in automobile top rear end medium position, aims at the positive back of car scenery; Camera is connected respectively to by circuit and is contained in the car, the chaufeur anterior locations, the cooresponding electronic display; Circuit power is provided by automobile power source.

Described three cameras also can use an electronic display jointly, control the camera of each position by a circuit resolving device, observe vehicle condition information.

The installation site of described camera can change according to automobile kind, purposes.

The camera that described camera has night vision function; The camera that also has writing function; Also existing night vision function also has the camera of writing function.

Because technique scheme, cancelled the back mirror of present automobile, substitute with camera, make when chaufeur is driven, all the time eye to the front, needn't left and right rotary head, when needing to understand the vehicle condition information at car rear, need only be slightly to the read-out in catotropia the place ahead, car is left and right, the vehicle condition information at rear just comes into plain view.Improved the observation efficiency of driving, it is convenient, light to observe.In addition, also saved the outside occupation space of car body, reduced the chance that scratches with unpowered vehicle, bicycle, pedestrian, also reduced the area that automobile takies road surface, parking place, enlarged the visual field in chaufeur the place ahead simultaneously, chaufeur can not be subjected to the outer weather effect of car, observes information behind the car at any time, has improved the safety factor of driving.During night travel,, can guarantee the observing effect at night by increasing the camera of night vision function.If use camera with writing function, can also note driving live telecast at any time, make things convenient for the correct judgement and the processing of traffic accident.
