Description

Automobile rearview mirror

The utility model relates to the automobile optics, more clearly says so to be used for running, reversing, to turn, to turn around, make during lane change chaufeur accurately, clearly to observe the automobile rearview mirror of situation behind the car.

Traditional automobile rearview mirror is a kind of catadioptre.This catadioptre field of view is little, inaccurate, unintelligible, and more outstanding shortcoming is the situation of the rear lower of car particularly in can't see behind the car closely, and a backsight blind area is arranged.Solid photography/videography device (CCD) automotive rear-view system occurred abroad in recent years, and it has eliminated shortcomings such as blind area, and wide-angle view is arranged, and is also clear.But the pick-up lens of this back mirror generally is installed in the rear upper end of automobile bodies outside, does not also install anti-joyride device.This structure is easily destroyed or stolen, and is not suitable for China's actual conditions.In addition, its demonstration is fixed on the operator platform, in fact will reequip existing automobile.And its setting range that shows the angle is less, is not easy to the driver and arbitrarily observes.

The purpose of this utility model, be to overcome above-mentioned shortcoming and defect, a kind of backsight blind area of having eliminated is provided, wide-angle view is arranged, can accurately, clearly observe situation behind the car, be difficult for destroyedly, can report to the police rapidly when stolen, be fit to China's actual conditions, and can reequip existing automobile, easy for installation, the display register scope is big, automobile rearview mirror easy to adjust.

In order to achieve the above object, the utility model automobile rearview mirror is by the solid-state image pickup camera lens that is installed in automobile rear, be installed in solid-state image pickup camera lens back by the solid opto-electronic pickup, image processing and transmission circuit, the electronic circuit that function conversion circuit is connected and forms links to each other with cable with electronic circuit and the telltale that is installed in the operator's compartment is constituted.The groundwork of solid photographic device (CCD), be with pick-up lens take the photograph optical signal, with the solid opto-electronic pickup optical signal is converted to electric signal again, electric signal is again through image processing and transmission then, function conversion, in telltale, demonstrate at last former take the photograph optical signal.Solid-state image pickup camera lens of the present utility model outside is installed with protective cover, with dustproof, waterproof, antitheft.Protective cover is fastened on automobile rear with screw, the inside, compartment.Protective cover is by having convex shoulder and being positioned at the lens bracket of the fixed orifice on the convex shoulder on the wiring board that is fixed on solid-state image pickup camera lens and electronic circuit, the outer cover that has biconvex shoulder and mounting hole, be installed in the packing seal between outer cover and the automobile bodies, the bolt shaft and the jam nut that lens bracket are installed on the biconvex shoulder of outer cover constitute.The front portion of outer cover has gate, and gate abuts against by packing seal on the back upper place car windshield of automobile, and camera lens can absorb image behind the car by windshield.Camera lens is a wide-angle, is installed in inboard, railway carriage or compartment behind the automobile, has eliminated the blind area of the automobile back lower place.The convex shoulder of lens bracket is installed in the biconvex shoulder of outer cover with bolt shaft and jam nut.The releases pin jack panel, lens bracket can turn an angle with respect to outer cover around bolt shaft, to regulate the angle between camera lens and the ground.The convex shoulder end of lens bracket has small embossment or decorative pattern, so that regulate.Solid of the present utility model is taken the photograph camera lens also can be installed in the outside, compartment, to adapt to dissimilar automobiles and lorry.

Telltale of the present utility model is installed on the base, and base is fixed on the vehicle cab with fastener or Acrylic Foam Tape or preceding windscreen top.The center has the pedestal that the axis hole side has the tightening screw to base on the automobile by being fixed on, be installed in the axis hole of pedestal and have the pivot of boss, middlely be fastened on screw that two ends on the pivot are fixed on the carriage on the shell of telltale and the holding screw that is installed in the tightening screw of pedestal is constituted.The two ends of carriage have the deep-slotted chip breaker that the concentric mounting screw of fixed orifice that a mounting screw uses and and fixed orifice is used.Every end of carriage all has two screws that telltale is fixed on the carriage.After one of them screw unclamps, the suitable angle that telltale can be tilted, screw is tightened nail at last along the deep-slotted chip breaker relative motion again at this moment, thus the angle that telltale can be tilted require in vertical direction.Unclamp holding screw, carriage can rotate in the horizontal direction together with telltale.Tighten holding screw again, the angle that telltale just tilts to require in the horizontal direction.The setting range of telltale is big, adjusts very convenient.The base of telltale can be bonded on the operator platform with double faced adhesive tape, and needn't reequip this moment to automobile, but the floor space of base should be bigger, to keep enough cohesive forces.

Can have cavity in the pedestal of the base of telltale, broken circuit alarmer is installed in the cavity.The normally closed switch of broken circuit alarmer i.e. a lead, and it is fixed in the protective cover of body camera outside.Broken circuit alarmer can be an audible alarm, and this moment, cavity should have the lid that spreads out of sound with holes.When the thief steals the solid-state image pickup camera lens, connect cable and comprise that the lead as normally closed switch cuts off, this moment, broken circuit alarmer will send sound and light alarm because of opening circuit, and informed that the driver takes corresponding action.The physical circuit of broken circuit alarmer is a lot, and we will be further specified in the following embodiments.On automobile rearview mirror, install broken circuit alarmer additional and can prevent that the solid-state image pickup camera lens is stolen, is particularly suitable for national conditions.

Task of the present utility model comes to this and finishes.

The utility model provides a kind of backsight blind area of having eliminated, and uses wide-angle can reach more than 150 °, affords a wide field of vision, imaging is accurate, clear, undistorted, waterproof, shockproof, dustproof, anti-theft capability is strong, is fit to China's actual conditions, the installation aspect, the automobile rearview mirror that setting range is big.It can be B/W dissplay or color display, also can infrared night vision.Can be widely used on vehicles such as car, utility van, este wagon, jeep, passenger vehicle, lorry and the portable construction machinery and equipment.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further explanation.
