Description

The present invention relates to an auxiliary component for expanding the field of view of a side mirror of a vehicle.

Side mirrors are provided on the right and left sides of the vehicle body so that the vehicle driver can observe the rear and lateral directions of the vehicle. This side mirror is provided to ensure the driver's driving field of view, and at the same time, to be able to see other vehicles traveling in the adjacent lane, but in the conventional side mirror, other vehicles traveling in the adjacent lane When the vehicle approaches the host vehicle from behind, the other vehicle has a so-called blind spot that cannot be recognized by being deviated from the image of the side mirror of the host vehicle. As a measure for eliminating this drawback, there is a demand for a simple method that does not cost much.

The side mirror of the vehicle allows the vehicle driver to visually check other vehicles traveling in the rear and lateral directions of the vehicle and easily visually check other vehicles approaching the adjacent lane from the rear, particularly vehicles entering the blind spot, It is extremely important to have a function that can ensure driving safety. However, it is also an important issue in traveling safety that the vehicle in the adjacent lane can be confirmed without greatly changing the driver's line of sight.

The form of the conventional vehicle side mirror is the current form of a mirror surface with a slight curvature through the accumulation of years of experience so that the driver can easily secure the rear view. When driving a conventional driver, the driver determines the situation of other vehicles in the vicinity of his / her car while looking at the balance between the rear view seen in the rearview mirror and the lateral rear view seen in the side mirror. ing. Therefore, it is desirable that what is called a blind spot can be taken by a method that does not affect the function of the conventional side mirror.

In consideration of the above problems, the present invention is a device in which the vehicle side mirror is provided with a function of visually confirming other vehicles in the so-called blind spot traveling in the lane adjacent to the vehicle.

In order to make up for the restriction of the field of view of the vehicle side mirror, a small mirror body with a wide field of view is attached.

A convex mirror surface (or concave mirror surface) 3 having a curvature (for example, 30R) higher than the curvature (generally 1000R) of the vehicle side mirror (both right and left), that is, the component of the present invention is used as an auxiliary component for the side mirror ( Hereinafter, as a secondary mirror surface body), by adhering or joining the main mirror surface (hereinafter referred to as the main mirror surface) 2 of the vehicle side mirror, other vehicles in the lateral rearward direction of the driver's next lane, particularly so-called blind spots. Facilitates visual confirmation of the vehicle entering.

The secondary mirror surface is a convex mirror surface (or concave mirror surface) having a curvature (for example, 30R) higher than the curvature (generally around 1000R) of the main mirror surface (hereinafter, the main mirror surface) so as to have a wider field of view than the main mirror surface, The image of the other vehicle in the lateral rearward direction of the adjacent lane is arranged in the main mirror surface so as to enter the driver's field of view as an image in the sub mirror body.

The function of observing other vehicles in the so-called blind spot is almost the same regardless of the location where the secondary mirror surface is placed, either on the side near the vehicle body, outside the vehicle body, or in the center if it is in the main mirror surface. It is desirable that the portion has little influence on the original traveling monitoring function, that is, a portion that is as close to the vehicle body as possible.

The size of the sub-mirror is selected appropriately depending on the size of the vehicle, etc., but the area occupied by the sub-mirror is not to hinder the original function of the main mirror as a vehicle side mirror. It is desirable that the size be suppressed to 2/5 or less of the main mirror surface.

The vehicle side mirror provided with the mirror body (secondary mirror body) that expands the vehicle field of view of the present invention described above is a visual confirmation of the other vehicle in the lateral rear direction of the adjacent lane, particularly the other vehicle hidden behind the blind spot. This is possible without greatly deviating the line of sight of the vehicle and contributes to the traffic safety of vehicle travel.

Hereinafter, the form in the case of implementing this invention component in a vehicle side mirror is demonstrated based on FIG. 1 for the right side mirror. The left side mirror will not be described with respect to the same principle as the right side mirror.

By attaching the sub mirror body 3 near the body of the main mirror surface 2 as shown in FIG. 1, the field of view of the side mirror is widened from the β angle to the α angle, and the driver's field of view is approximately 50 degrees by selecting an appropriate curvature. Improvement is possible.

As for the curvature of the secondary mirror body, an appropriate round is selected depending on the size of the vehicle, but in the case of a general passenger car, 33R (+10, −5) is appropriate.

The shape of the sub-mirror body is the half-moon-shaped spherical body 3 shown in FIG. 2 or a circular spherical body. However, in the case of a circular spherical body, the image of the vehicle occupies the vehicle body side half of the image of the sub-mirror body.

The sub mirror body does not necessarily have to be attached to the vehicle body, but is preferably attached to a portion near the vehicle body so as not to hinder the original view confirmation function of the vehicle side mirror.

It is also possible to make the curvature of the secondary mirror surface a negative curved surface (concave surface). In this case, since the image of the vehicle other than the adjacent oblique line is displayed in the opposite direction to the case of the plus curvature, it is difficult for the driver to see.

Hereinafter, the utility by the expansion of the field of view by the vehicle side mirror equipped with the secondary mirror body according to the present invention will be described.
When traveling by a vehicle, the driver checks the traveling state of other vehicles around the vehicle with images displayed on the rearview mirror and side mirror for safety of traveling. Eventually, when another vehicle approaches the adjacent lane from the rear at a higher speed, it is first visually recognized by the image of the other vehicle in the mirror of the rear mirror of the own vehicle and the side mirror. Eventually, as the distance between the other vehicles approaches, the image of the other vehicle gradually flows to the right from the center of the mirror of the rearview mirror and side mirror. The existence of a car is not understood.
In such a case, the image of the other vehicle is still displayed on the secondary mirror body of the present invention, and the driver visually confirms the image of the other vehicle reflected on the secondary mirror body and there is another vehicle in the adjacent lane. Recognize that you can travel. As other vehicles run side by side with their own vehicles and further overtake, the images of other vehicles appearing on the sub-mirrors gradually flow to the right side of the sub-mirrors and go out of sight. If it reaches the position, the position of the other vehicle is already in the position directly related to the driver of the host vehicle and is within the range of the field of view of the driver of the host vehicle. No.

In vehicle travel, the driver's tension used to identify whether there is another vehicle in the blind spot of the adjacent lane is high, so improvement of this problem is important in ensuring the safety of travel. The present invention can be easily attached to a side mirror of an existing vehicle by bonding or the like as an auxiliary part for expanding the field of view, and contributes to the safety of vehicle traveling, particularly to prevent a contact accident.
