Abstract
The utility model provides a rear-view lens for a locomotive. The rear-view lens comprises more than one attention area, wherein each attention area is used for reflecting different areas in an environment where the locomotive is positioned. According to the external rear-view mirror lens, ten attention areas are formed through the changes of parts, shape, area, curvature, inclination and height on the lens, so that the front part, middle part and tail part of the outer side of the vehicle body, the grounding range of the outer side of the front and rear wheels of the vehicle, the ground below the outer side of the vehicle tail, the vehicle side area of the byroad outside the vehicle, the vehicle rear area of the byroad outside the vehicle, the vehicle side area beyond the byroad outside the vehicle and the vehicle rear area beyond the byroad outside the vehicle are reflected, and a visual field range of the driver is effectively widened.
Description
Technical field
The utility model belongs to the automotive component field, relates to a kind of vehicle exterior sided mirror unit eyeglass and back mirror thereof, relates in particular at a minute surface by ten automobile rear view mirror lens and back mirrors thereof of paying close attention to the district of spline surface smooth connection.
Background technology
The power actuated vehicles such as automobile are in operational process, and the driver comes observation side back car and rear situation by the outer sided mirror unit of car.Because common backsight minute surface is single curvature, the visual field is limited, is mainly used in observing vehicle rear side, can not see sending a car in positive side, tailstock obstacle, front and back wheel and the road surface of cutting.
Because it is regional limited that this minute surface can be concerned about, when driver's lane change or turning, meet accident easily, can not see wheel condition and ground location thereof during driving, be difficult to observe the wire frame on parking stall during parking, also be difficult to observe tailstock section and distance between car and obstruction during reversing.
Although its driver of part vehicle is arranged by a plurality of back mirrors that install additional the scope of broadening one's vision, also have vehicle to understand the distance of the tailstock and rear obstacle by the Reverse Sensor that installs additional, these behave programs complexity, expense are high, also not directly perceived.Obtaining with great visual angle, but bonding little convex lens comes off some vehicle easily, also affects attractive in appearance to the little convex mirror of bonding one side on the back mirror; Especially, the image in the little convex lens and the image in the back mirror are misfitted, and cause easily the driver visually to judge by accident.In addition, the user can't freely select own putting of liking.
Thus, industry needs a kind ofly to have the backsight eyeglass and the back mirror thereof that enrich the visual field and expect to some extent.
The utility model content
The utility model aims to provide a kind of backsight eyeglass and back mirror thereof that enriches the visual field that have.
In order to reach above-mentioned purpose, an aspect of the present utility model is a kind of automobile-use backsight eyeglass, comprises more than one concern district, and described concern district is used for reflecting the zones of different of described self-propelled vehicle environment of living in.
Among some embodiment, described eyeglass comprises the concern district of ten reflection zoness of different, that is, reflection vehicle body exterior front, the car front-wheel outside contact to earth ten of zone, car side beyond the outer side line of car rear area, car beyond the car rear area, the zone, car side of the outer side line of car, the outer side line of car of the lower ground of scope, the tailstock outside, the tailstock outside, the outer side line of car of scope, the outer middle side part of vehicle body, the back wheels of vehicle outside that contact to earth pay close attention to and distinguish.
Among some embodiment, the position in each described concern district, area, shape, curvature, adjust as the basis take plane mirror with respect to inclination angle and the height of lens design reference plane, so that each mirror image of paying close attention to the district accurately clearly reflects respective regions.
Among some embodiment, pay close attention to the district for described ten and be divided into three groups according to the position on described eyeglass, wherein, pay close attention to the minute surface part that the district is positioned at close vehicle body for first group, part has three to pay close attention to the district on it, from outwards be used for successively reflection vehicle body exterior front, middle part and afterbody near vehicle body, its underpart also has three to pay close attention to the district, is used for successively the ground of reflection front and rear wheel lateral surface under contacting to earth outside scope and the tailstock; Pay close attention to for the 3rd group and distinguish the minute surface part that is positioned at away from vehicle body, its underpart has one to pay close attention to the district, is used for reflection car nearside lame zone, car side in addition, and part also has one to pay close attention to the district on it, for the car rear area beyond the reflection car nearside lame; Pay close attention to the district for second group and be positioned between first group and the 3rd group, its underpart has one to pay close attention to the district, is used for the zone, car side of reflection car nearside lame, and part also has one to pay close attention to the district on it, is used for the car rear area of reflection car nearside lame.
Among some embodiment, described first group of area sum of paying close attention to the district is less than described second group of area sum of paying close attention to the district, and the 3rd group of area sum of paying close attention to the district is also less than described second group of area sum of paying close attention to the district.
Among some embodiment, in same group is paid close attention to, be positioned at the area in described concern district of minute surface below less than the area in the described concern district of its top.
Among some embodiment, shape profile, surface configuration, and the curvature in described concern district is determined in the zone of reflecting according to described concern district.
Among some embodiment, pay close attention between the district for described ten and be provided with the gap, close so that the mirror image that each described concern district is reflected is naturally continuous with level and smooth benefit of Bicubic Spline Surface in described gap.
Among some embodiment, the height of each relative lens design reference plane in described concern district is set to, and accurately clearly reflects under the prerequisite of described self-propelled vehicle proceeds posterolateral zone so that the surf deform in described gap is minimum at its mirror image that reflects.
Of the present utility model is a kind of automobile-use back mirror on the other hand, comprises aforementioned backsight eyeglass; And attaching parts, it is connected to described backsight eyeglass on left side or the right side of described self-propelled vehicle.
The external mirror having indicator light eyeglass that the utility model provides, in the variation of eyeglass by position, shape, area, curvature, inclination angle and height, build ten and pay close attention to the district with reflection vehicle body exterior front, middle part and afterbody, the car front and rear wheel outside scope of contacting to earth, lower ground, the tailstock outside, the car side of the outer side line of car is regional, the car rear area of the outer side line of car, zone, car side beyond the outer side line of car, the car rear area beyond the outer side line of car has enlarged driver's field range effectively
