  However, in the above-described conventional outside-viewing device, if each mirror is a convex mirror in order to widen the field of view by each mirror, the reflected image is reduced. On the other hand, if each mirror is a concave mirror in order to enlarge the reflected image of each mirror, the field of view is narrowed. Moreover, since the direction of each mirror is restricted by the direction to be visually recognized and the position of the driver's viewpoint, the reflected image cannot be adjusted to be easily visible to the driver. Due to these restrictions, it is difficult to improve the visibility with the conventional vehicle outer mirror.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an out-of-vehicle visual recognition device that can improve the visibility on the passenger seat side outside a vehicle during driving.

The present invention is a vehicle exterior visualizing device that makes it possible to visually recognize the vehicle exterior on the passenger seat side.
A back viewing window that is disposed in the passenger compartment and allows a rear image on the passenger side to be visible outside the vehicle;
An auxiliary visual recognition window that is disposed in the passenger compartment and is formed smaller than the opening area of the back visual recognition window, and that allows an image other than the rear outside the vehicle on the passenger seat side and the height of the vehicle to be visible, and
Looking at the vehicle in a bird's-eye view (flip) state, the area behind the driver on the passenger side is the back visual recognition area visible from the back visual recognition window, and the area positioned in front of the back visual recognition area, When the auxiliary viewing area is visible from the auxiliary viewing window,
The center of the auxiliary viewing window viewed from the driver is arranged above the center of the back viewing window.

  In this outside-viewing device, the opening area of the back viewing window is made larger than the opening area of the auxiliary viewing window, so that the driver's line of sight can easily reach the back viewing window, and the rear viewing is performed during normal driving. easy. Moreover, since the opening area of the auxiliary visual recognition window is made smaller than the back visual recognition window, it is easy for the driver to recognize that the auxiliary visual recognition window is used for assistance. For these reasons, the visibility on the passenger seat side outside the vehicle during driving can be improved. Furthermore, when the auxiliary visual recognition area is positioned in front of the back visual recognition area, the center of the auxiliary visual recognition window viewed from the driver is disposed above the center of the back visual recognition window. This makes it easier to recognize which position around the vehicle the driver is viewing with the auxiliary viewing window. This is due to the fact that the driver recognizes the front, rear, left and right in a state of looking down at the own vehicle. In other words, when you look down on your vehicle, your eyes move up and down when you follow the front and back of your vehicle, which corresponds to your eyes moving up and down in the driver's seat. This is because the movement of the eyes to the left and right when following the left and right of the vehicle corresponds to the left and right movements of the eyes in the driver's seat. Thus, the present invention uses the driver's consciousness to reduce the auxiliary visual recognition window or change the position of the auxiliary visual recognition window with respect to the back visual recognition window. The visibility on the seat side can be greatly improved.

The present invention is a vehicle exterior visualizing device that makes it possible to visually recognize the vehicle exterior on the passenger seat side.
A back viewing window that is disposed in the passenger compartment and allows a rear image on the passenger side to be visible outside the vehicle;
An auxiliary visual recognition window that is disposed in the passenger compartment and is formed smaller than the opening area of the back visual recognition window, and that allows an image other than the rear outside the vehicle on the passenger seat side and the height of the vehicle to be visible, and
When the vehicle is viewed in a bird's-eye view, the area behind the driver on the passenger side is the back viewable area that can be seen from the back view window, and the area located outside the back view area When the auxiliary viewing area is visible from the auxiliary viewing window,
The center of the auxiliary visual recognition window viewed from the driver is arranged outside the center of the back visual recognition window.

  In this outside-viewing device, the opening area of the back viewing window is made larger than the opening area of the auxiliary viewing window, so that the driver's line of sight can easily reach the back viewing window, and the rear viewing is performed during normal driving. easy. Moreover, since the opening area of the auxiliary visual recognition window is made smaller than the back visual recognition window, it is easy for the driver to recognize that the auxiliary visual recognition window is used for assistance. For these reasons, the visibility on the passenger seat side outside the vehicle during driving can be improved. Furthermore, when the auxiliary visual recognition area is located on the outer side of the back visual recognition area, the center of the auxiliary visual recognition window viewed from the driver is disposed on the outer side of the center of the back visual recognition window. This makes it easier to recognize which position around the vehicle the driver is viewing with the auxiliary viewing window. This is due to the fact that the driver recognizes the front, rear, left and right in a state of looking down at the own vehicle. In other words, when you look down on your vehicle, your eyes move up and down when you follow the front and back of your vehicle, which corresponds to your eyes moving up and down in the driver's seat. This is because the movement of the eyes to the left and right when following the left and right of the vehicle corresponds to the left and right movements of the eyes in the driver's seat. Thus, the present invention uses the driver's consciousness to reduce the auxiliary visual recognition window or change the position of the auxiliary visual recognition window with respect to the back visual recognition window. The visibility on the seat side can be greatly improved.

Further, when the auxiliary visual recognition area is ahead of the back visual recognition area, the center of the auxiliary visual recognition window is shifted from the center of the back visual recognition window and to the driver's seat side.
Such a configuration is effective when the auxiliary visual recognition area is in the vicinity of the front wheel or the headlight on the passenger seat side outside the vehicle. Also in this case, the driver recognizes that the auxiliary visual recognition area is closer to the driver than the back visual recognition area because the driver recognizes the own vehicle in an overhead view. It depends. Therefore, in the present invention, the center of the auxiliary viewing window is shifted to the driver's seat side from the center of the back viewing window.

(1) When the vehicle 47 is viewed in an overhead state, the area behind the driver P on the passenger seat side behind the driver P is defined as a back visual recognition area R1 that can be viewed from the back visual recognition window M1, and this back visual recognition area R1 When the outer side region is an auxiliary visual recognition region R4 that is visible from the auxiliary visual recognition window M4 (see FIG. 15B), the center O4 of the auxiliary visual recognition window M4 viewed from the driver P is the back visual recognition window. It is arranged outside the center O1 of M1.

  The outside-viewing device 41 has the same function and effect as the outside-viewing device 1 of the first embodiment, and a description thereof is omitted.

  As shown in FIG. 16, in the case of a left-hand drive vehicle, the outside-view device 41 is provided above the right front wheel of the vehicle 47. The positional relationship between the back viewing window M1 and the auxiliary viewing window M4 is based on the technical idea as described in (1) above. 15, the same reference numerals as those in FIG. 16 are given.

  The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention.

  For example, the auxiliary visual recognition window M2 or the auxiliary visual recognition window M3 may be disposed directly above the back visual recognition window M1.

  If the auxiliary visual recognition windows M2 to M4 are separated from the back visual recognition window M1 as much as possible, there is a low possibility that the auxiliary visual recognition windows M2 to M4 and the back visual recognition window M1 are mistaken. It is preferable to determine the minimum distance from M1 in consideration of the human viewing angle. By separating the viewing angle by more than the viewing angle, it is possible to avoid the auxiliary viewing windows M2 to M4 and the back viewing window M1 from being recognized simultaneously by the driver. As a result of the experiment, it is preferable to consider a viewing angle of 5 degrees.
