In order to conquer the disadvantages of the ordinary plane rear-view mirror that the start point of the visual field is late, and the transverse visual field is narrow; on the basis of the dimension of the various original plane lenses, the curvature radius of the spherical surface of the lens is between R600 mm and R1800 mm, the plane lenses are respectively made into various spherical wide-field rear-view lenses of different curvature radius, and the various spherical wide-field rear-view lenses are provided with frame protecting plates; thereby, the serial products of concealed wide-field rear-view mirrors can be formed. A driver can select the concealed wide-field rear-view mirror according to the respective eyesight requirement. When the utility model is installed, the utility model can be glued on a plane mirror only by using an adhesive layer of double faces; so the utility model can be covered on the whole plane mirror, and the utility model has the advantages of clear visual field, wide range.

Description

Automobile is extensively looked back mirror with implicit form

The utility model relates to the back mirror of automobile, and especially the implicit form used of automobile both sides is extensively looked back mirror.

Automobile rearview mirror is to specialize in the dynamic change that the driver is used for observing vehicle right and left both sides and two proceeds posterolateral all situations, and is very important to traffic safety.At present in the automobile of travels down, the automobile that significant proportion is arranged, what equip is planar optics type back mirror, be characterized in that technology is quite simple, technology content and productive costs are very low, but maximum shortcoming is that field range is very little, the effect starting point is very slow, substantially only see from the later road surface situation of the tailstock, and visual field band is narrower, whenever the automobile lane change, turn, can't observe and understand at all the contiguous pedestrian in vehicle right and left both sides when keeping to the side, bicycle, or the situation of Automobile Dynamic variation, so the traffic accident that takes place in the vehicle body left and right sides will account for the large percentage in the whole traffic accident sum, therefore flat rearview mirror has not adapted to busy day by day, crowded road, especially car rear-view, the back mirror of unified type just when a certain model is dispatched from the factory can't resemble at all and can require according to the visual field separately and the range estimation custom at ordinary times the lorry, arbitrarily choose the back mirror of different size.In order to remedy the defective of flat rearview mirror, existing two kinds of pocket sphere wide-angle rear-view mirrors that can stick on angle on the plane mirror as auxilliary mirror on the market for the driver, be divided into two kinds on garden type and square type, garden type minute surface diameter is in 60 millimeters of φ, the rectangle minute surface is in long 80 millimeters * wide 50 millimeters, in the mirror radius of curvature of sphere all at the R60 millimeter between the R120 millimeter, though field range is extremely wide, but eyeglass area and sphere curvature radius are all too little after all, the personage's scene that reflects from minute surface is too little, just smudgy to the situation of observing tailstock rear, can only watch the contiguous situation in vehicle body both sides, still will go to observe by primary mirror (plane mirror) to the situation on the later road surface of the tailstock, main like this, auxilliary mirror wants continuous land wheel stream to see, disperse driver's energy easily, can not reach open-and-shut effect.

Task of the present utility model is to keep former car whole perfect, do not change under the prerequisite of original-pack back mirror shell, provide a kind of convenient as wearing contact lenses, and the very wide back mirror in the visual field can very clearly be unified into a slice to wide visual field behind automobile both sides adjacent domain and the car.

For solving above-mentioned task, the solution that the utility model adopts is: the oad of the flush type backsight eyeglass that is equipped with according to various former cars is the basis, according to the range estimation requirement different when the driving of optical principle and human visual to surrounding environment, for the visual field starting point that makes back mirror fully shifts to an earlier date, the band of having a wide sphere of vision is expanded in both sides as far as possible to the left and right, therefore the radius of curvature of eyeglass sphere at the R600 millimeter to the serial Wide-field mirror sheet of making the different spheres of many moneys between the R1800 millimeter respectively, distinguishing variously or the automobile of travels down to adapt to.

Thisly extensively look back mirror with implicit form by Wide-field mirror sheet, goggle deckle board formed automobile, the extrados that it is characterized in that the Wide-field mirror sheet be its radius of curvature of sphere at the R600 millimeter between the R1800 millimeter.

The advantage of the technical program is: any part in addition in the flush type back mirror that need not change former car equipment and back mirror or only dismantle planar optics and the goggle deckle board, just can reach high-grade function of extensively looking back mirror, have that cost is low, loading, unloading are efficient and convenient, product seriation has bigger choice.Can make road behind vehicle right and left both sides transverse area and the car be unified into the broad horizon band of a slice, whenever automobile meeting, situation such as overtake other vehicles, overtaken other vehicles, turn, keep to the side can both grasp initiative to traffic safety to dynamically the coming into plain view of motor vehicle environment.

Be described further below in conjunction with embodiment and accompanying drawing thereof:

Fig. 1 is the constructional drawing of automobile with the implicit form Wide-field mirror.

Fig. 2 is the flush type rear-view mirror figure that former car is equipped with.

Fig. 3 is the visual field band and the visual field band scheme drawing that sticks after implicit form is extensively looked back mirror of flush type back mirror.

Referring to accompanying drawing.Embodiment shown in Figure 1 is made up of Wide-field mirror sheet 1, goggle deckle board 2, and goggle deckle board back forms stickup face and is used for being adhesively fixed with former car minute surface.R is the spherical outside surface radius of curvature of Wide-field mirror sheet, and it is selected for use according to the category of roads that often travels and the situation of different regions.To through the most crowded, the bustling road of being everlasting, two, traveling automobile should be selected certain implicit form and extensively looks back mirror in the spherical outside surface R of Wide-field mirror sheet 1 value is between 600 to 1200 millimeters on the tertiary highway.As frequent or long-time automobile, then should in the R of spherical outside surface value is between 1200 to 1800 millimeters, remove to select certain implicit form and extensively look back mirror at I and II highway, running on expressway.

Existing apparatus shown in Figure 2 is the flush type back mirror.Wherein the mirror shell 4, planar optics 5, goggle deckle board 6, extensively look the stickup face 3 of back mirror back as long as utilize implicit form, stick layers of two-sided, another side one pastes and get final product on original plane minute surface 5, or earlier original goggle deckle board 6 Lianping face eyeglasses 5 is unloaded together, directly is attached on the interior microscope base 7 of mirror shell 4 also can reach same effect.

Fig. 3 has represented that automobile of the present utility model extensively looks the back mirror result of use with implicit form, and it is obviously broader than original flush type mirror field of view.Wherein narrow lines represent it is the visual field band of flush type back mirror, can't see the contiguous transverse area in vehicle body both sides (being called blind area the most dangerous when driving a vehicle) from plane mirror.The summation that wide lines add narrow lines is exactly the visual field band of loading onto behind the implicit form Wide-field mirror.
