Abstract
The utility model discloses a rear-view distance-measuring mirror of a car. The rear-view distance-measuring mirror is mainly and structurally characterized in that visual distance grid lines are marked on the back surface of the mirror surface of the rear-view distance-measuring mirror, and are marked from the middle part to the two sides in a two-two symmetrical manner; and when driving the car and using the rear-view distance-measuring mirror, a driver watches the visual distance grid lines in the rear-view distance-measuring mirror of the car and can be very convenient to judge and measure the distance from the following rear cars according to the size of the projection of the car in the visual distance grid lines of the rear-view distance-measuring mirror, i.e., the principle that the larger the projection, the closer the distance between the cars.
Description
Technical field
The utility model relates to a kind of automobile rearview mirror, refers in particular to a kind of automotive rear-view iconometer that can test the back spacing.
Background technology
Automobile driver is seen the progressive automobile of accompanying at the back from back mirror under steam, often is difficult to judge distance.This makes chaufeur nervous easily at heart, as dodges the untimely traffic accident that accurately also is prone to cause.Develop a kind of automotive rear-view iconometer that can test the back spacing, for the protection driver safety, it is necessary reducing traffic accident.
The utility model content
The technical matters that the utility model will solve provides a kind of automotive rear-view iconometer, uses this automobile rearview mirror, can test the back spacing easily, with the protection driver safety, reduces traffic accident.
The technical matters that the utility model will solve is realized by following scheme: the automotive rear-view iconometer, comprise picture frame, minute surface, and it is characterized in that:, be marked with sighting distance ruling silk at the back side of said minute surface.
The utility model also can be realized by following scheme: said sighting distance ruling silk is two two symmetrical markings from the centre to both sides.
Effect of the utility model and advantage: when chaufeur drives to use this automotive rear-view iconometer; Watch sighting distance ruling silk in the automotive rear-view iconometer attentively; Size according to automobile projection in backsight iconometer sighting distance ruling silk; Be the nearlyer principle of the big more spacing of projection, can judge the distance of measuring retinue back automobile very easily.
Description of drawings
Fig. 1 is the front view of automotive rear-view iconometer.
The specific embodiment
As shown in Figure 1, sighting distance ruling silk 1 is engraved in the back side of automotive rear-view iconometer, it can be seen on the front of back mirror minute surface 2, and be not easy to come off.The line-spacing of sighting distance ruling silk 1 is fixed quarter by the width of back car projection in the backsight iconometer.As shown in Figure 1, sighting distance ruling silk 1 is two two symmetrical markings from the centre to both sides.Be divided into 5 meters/25 meters/45 meters 3 pairs.Back spacing is far away more, and the width of projection is more little in minute surface 2, and the line-spacing of sighting distance ruling silk 1 is more little, and vice versa.The width of sighting distance ruling silk 1 is that therefrom mind-set both sides symmetry is fixed quarter.The overall width of back car is the width average of miniature car.The line-spacing of sighting distance ruling silk 1 has shown the distance rice number of back car and this car.Like this, the back car projection of chaufeur sighting distance ruling silk 1 in seeing automotive rear-view iconometer minute surface 2, the distance of car after can recording.According to this principle, can in the inside and outside backsight iconometer of various automobiles, use.
Claims (2)
1. the automotive rear-view iconometer comprises picture frame, minute surface, it is characterized in that: at the back side of said minute surface, be marked with sighting distance ruling silk.
2. automotive rear-view iconometer according to claim 1 is characterized in that: said sighting distance ruling silk is two two symmetrical markings from the centre to both sides.
