Description

  The present invention relates to a side under mirror device for visually recognizing an object in a blind spot of a vehicle.

In the side under mirror device, there is a technique for projecting an object in front of the vehicle by a first reflecting mirror provided in a housing of a door mirror and a second reflecting mirror provided in a front pillar (for example, Patent Document 1). reference).
In addition, by arranging a plurality of mirrors in the vicinity of the window arranged between the front glass and the door glass of the vehicle and in the vehicle interior, the occupants can In some cases, an image below the side surface of the vehicle can be grasped without a sense of incongruity (see, for example, Patent Document 2).

  However, the conventional technique (Patent Document 1) can visually recognize the lower front of the door mirror, but cannot visually recognize the lower part of the door mirror or the vicinity of the left front door. It has been desired to make the blind spot formed below the door mirror and near the left front door smaller.

  Therefore, it is conceivable to reduce the blind spot that cannot be solved by Patent Document 1 by combining the technology of Patent Document 1 with the technology of Patent Document 1. By disposing a mirror (third reflecting mirror) different from the second reflecting mirror of Patent Document 1 in the vicinity of the second reflecting mirror, the side lower part in the vicinity of the door mirror that is difficult to see with the second reflecting mirror is provided. It can be projected.

  In Patent Document 2, an occupant can grasp the image below the side of the vehicle, but the images reflected on the three mirrors are almost the same size, so when multiple mirrors enter the field of view at the same time, The image of another mirror other than the one you want to see is obstructive. In particular, when the vehicle is moving at a low speed, the image of another mirror appears to flicker, so that the eyesight becomes more noticeable.

  That is, the mirror (second reflecting mirror) of Patent Document 1 is used in front of the door mirror, for example, when looking near the left front wheel, and is used when the vehicle is parked in parallel or when an obstacle is avoided. Often used when moving the vehicle in the vehicle width direction. That is, it is used when the vehicle is moving at a low speed, and an image at that time is shown.

On the other hand, the third reflecting mirror reflects the target part behind the door mirror and in the lower side part near the door mirror, at a height lower than the door window when the vehicle stops (when parked), and on the vehicle side part. It is often used to visually recognize an object placed near the. That is, the third reflecting mirror is used when the vehicle is stopped and displays an image at that time.
As described above, when the mirror (third reflecting mirror) of Patent Document 2 is adopted in Patent Document 1, when the vehicle is moving at a low speed, the third reflection is observed when the second reflecting mirror is viewed. The image reflected in the mirror (third mirror) appears to flicker, which is obstructive.
