Abstract

The automobile front view mirror comprises an objective lens and an ocular lens and is characterized in that the objective lens and the ocular lens are oppositely arranged, and an image in front of an automobile, the objective lens, the ocular lens and eyes of an automobile driver form a light path. In order to reduce the blind area of the front view of the automobile driver, the objective lens is arranged on the side, far away from the driver, of the head of the automobile, the eyepiece lens is arranged on the part, which is easy to be considered by the sight of the driver, and the image in front of the automobile is reflected to the eyepiece lens through the objective lens and finally received by the eyes of the driver. The objective lens is a convex (or planar) mirror; the eyepiece is a concave (or planar) mirror. The invention has the beneficial effects that: when a large block exists in front of the vehicle, the forward-looking blind area generated by the offset of the driver seat is greatly reduced, so that the driver can conveniently and correctly judge the road condition in front, and the driving safety of the vehicle is improved.

Description

A kind of automobile front-view mirror and its method for reducing front-view blind area

technical field

The invention relates to a structure of an automobile front-view mirror and a method for reducing a driver's front-view blind area.

Background technique

In order to ensure the safety of motor vehicles, rear-view mirrors are generally installed on the left and right sides of the cab, so that the driver can clearly distinguish the lane conditions behind the two sides of the vehicle; some vehicles are also equipped with down-view mirrors in front of the cab. So that the driver can see clearly whether there are obstacles in the blind spot that the driver directly sees before starting the vehicle, and judge whether the vehicle can start. However, once there is a large vehicle blocking the front of the vehicle, since the driver's seat is offset to one side of the vehicle body, such as in mainland China, the driver's seat is set on the left half of the front of the vehicle, and the driver looks forward to the front of the right half of the other side of the vehicle body. Blind spots will be generated, and it is often impossible to see the road conditions on the right side of the blocking vehicle ahead, and cannot correctly judge whether it is possible to bypass the large vehicle ahead from the right side, which causes inconvenience to the driver and even brings hidden dangers to the safe driving of the vehicle.

Contents of the invention

The purpose of the present invention is to overcome the defective of prior art, provide a kind of automobile front-view mirror and the method for reducing the blind spot of front view thereof.

In order to achieve the above object, the technical solution adopted is: a car front view mirror, including an objective lens and an eyepiece, which is characterized in that the objective lens and the eyepiece are arranged opposite to each other, and the image in front of the car, the objective lens, the eyepiece and the eyes of the driver of the car Make up the light path. In order to reduce the forward-looking blind spot, the objective lens is set on the side of the vehicle head far away from the driver, and the eyepiece is set at a place where the driver's eyes can easily see, and the image in front of the vehicle is reflected to the eyepiece through the objective lens. Finally received by the driver's eyes.

The objective lens is a convex reflector, or a plane reflector; the eyepiece is a concave reflector, or a plane reflector.

The beneficial effect of the present invention is that: when there is a large obstacle (vehicle) in front of the vehicle, the forward-looking blind area due to the offset of the driver's seat is greatly reduced, which is convenient for the driver to correctly judge the road conditions ahead, and is conducive to improving the safety of the vehicle.

Description of drawings

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Fig. 1 schematic diagram of optical path structure of the present invention;

Fig. 2 schematic diagram of the embodiment of the present invention;

Fig. 3 is a schematic diagram of another embodiment of the present invention.

In the figure: 1-driver; 2-eyepiece; 3-objective lens; 4-forward image; 5-forward blind spot; 6-blocking; 7-cantilever.

Detailed ways

Shown in dotted line in Fig. 1 is the scope that driver's 1 vision can directly observe and take into account, as seen from the figure, there is a large-scale forward-looking blind spot 5 between the dotted line and the front blocking 6. A kind of automobile front-view mirror of the present invention comprises objective lens 3 and eyepiece 2, and described objective lens 3 and described eyepiece 2 are oppositely arranged, and the image 4 in front of automobile, described objective lens 3, described eyepiece 2 and the eyes of automobile driver 1 Make up the light path. In order to reduce the forward blind spot of the driver 1, the objective lens 3 is arranged on the side of the vehicle head far away from the driver 1, and the eyepiece 2 is arranged on a position where the driver 1's eyes can easily see, and the vehicle front image 4 ( In Fig. 1, a tricycle rider) is reflected to the eyepiece 2 by the objective lens 3, and finally received by the eyes of the driver 1.

The objective lens 3 in the automobile front view mirror is a convex reflector, or a plane reflector; the eyepiece 2 is a concave reflector, or a plane reflector.

From Fig. 1, the objective lens 3 and the eyepiece 2 can be fixedly arranged on the inner side of the car head compartment or the console of the driver 1 through a bracket.

It can also be seen from Fig. 1 that the front blind spot of the driver 1 is greatly reduced after adopting the present invention.

In the embodiment of Fig. 2, the objective lens 3 is fixed on the inner side of the car head compartment away from the driver 1 or on the driving console through a bracket, and the eyepiece 2 is fastened to the cantilever 7 of the rearview mirror through a clamp on the bracket. .

In the embodiment of Fig. 3, the objective lens 3 is fixed on the inner surface of the car head compartment away from the driver 1 side or on the driving console by a bracket, and the eyepiece 2 is fixed on the console where the driver's front eyes are easy to take into account by a bracket.
