Description

  The present invention relates to a vehicle exterior visual recognition device, and more particularly to a vehicle exterior visibility device for visually recognizing a blind spot outside a vehicle from a driver's seat.

  2. Description of the Related Art Conventionally, an automobile is provided with a vehicle exterior visual recognition device for visually recognizing the exterior of a vehicle that can be a blind spot when viewed from the front, rear, left, and right windows provided on the upper side of the vehicle when turning left or reverse. A side mirror or the like is provided to make it possible to visually recognize such a blind spot, and in order to further assist the visual recognition by the side mirror, for example, the lateral portion of the side of the passenger seat when turning left can be visually recognized from the driver's seat. For this reason, there is a type in which a viewing window is provided in the lower part of the passenger seat door.

  However, the above-described viewing window provided on the passenger seat side is effective for visually confirming when making a left turn, but there is a problem that the inside of the vehicle can be seen from the outside when the vehicle stops or goes straight. In order to solve such a problem, for example, a shutter that can be opened and closed is provided in the viewing window, and the shutter is opened only when necessary when turning left so that a portion that is difficult to see when turning left can be seen (for example, Patent Documents). 1).

  However, when a viewing window is provided as in Patent Document 1, a field of view for a range that can be directly viewed through the viewing window can be secured, but the road surface condition immediately below the side door cannot be viewed. There was a problem.

  On the other hand, the part that is difficult to see from the driver's seat of the vehicle is not limited to the outside of the side vehicle on the passenger seat side, and there is also a lower part in the vicinity of the vehicle body at the rear of the vehicle. There is a mirror provided on the back surface (see, for example, Patent Document 2). In this case, by attaching the mirror so that the state of the lower rear portion of the vehicle can be seen, the lower rear portion of the vehicle moved to the mirror via the rear window can be visually recognized. However, in order to visually recognize the road surface condition in the vicinity of the vehicle outside and under the vehicle, it is necessary to attach a mirror at a position close to the vehicle body surface outside the vehicle, and when a mirror is provided on the air spoiler at the rear of the vehicle, There is a problem that the area is limited and a wide field of view cannot be secured.

In order to solve such problems and realize that it is possible to easily see the road surface condition near the vehicle outside and outside the vehicle when necessary and to ensure a wide field of view without being looked out from outside the vehicle when it is unnecessary. In addition, in the present invention, a visual window (3) provided in the vehicle (1) for visually recognizing the outside of the vehicle from the driver's seat, and a louver device (6) disposed in the vicinity of the visual window. The louver device has a plurality of movable plates (8) that can be opened and closed, and the plurality of movable plates can set a predetermined opening state that is obliquely opened at a predetermined opening toward the driver's seat side. And a reflecting mirror (11) is provided on one side of at least a part of the plurality of movable plates for reflecting the outside of the vehicle so as to be visible from the driver's seat in the predetermined opening state . Opposite the reflecting mirror of one of the movable plates adjacent to each other The second reflecting mirror on the opposing surface of the movable plate of the square (13) is assumed to be provided.

  According to this, since the reflecting mirror is provided on the movable plate of the louver device that can confirm the outside of the vehicle through the visual recognition window and can be prevented from being seen from the outside of the vehicle when unnecessary, the movable plates are arranged in parallel. In a known louver device, in addition to being able to visually recognize the outside of the vehicle directly through the visual window by opening a plurality of movable plates and making them parallel to each other, by setting a predetermined opening (angle), A portion of the viewing window near the outside of the vehicle and close to the vehicle body can be viewed with a reflecting mirror. In the case where the reflecting mirror is provided on a plurality of movable plates, the outside of the vehicle can be visually recognized with a width equal to or larger than the viewing window that is the range in which the plurality of movable plates are disposed. Even in a narrow case, the overall reflection area is large due to the plurality of reflecting mirrors. And the range which can be visually recognized via a reflective mirror can be added to the range which can visually recognize the exterior of a vehicle directly through the said visual recognition window, and visual recognition in a wide range is possible with respect to the exterior of the vehicle of a visual recognition window.

  In particular, it is preferable that the second reflecting mirror (13) is provided on the opposing surface of the other movable plate facing the reflecting mirror of one of the movable plates adjacent to each other. For example, when a viewing window is provided at the lower part of the passenger side door and the lower part of the viewing window near the outside of the vehicle is viewed with a reflecting mirror due to the inclination of the movable plate, a louver device is placed below the driver's eye point. If this is done, it may be difficult to directly see the reflector that reflects the road surface. On the other hand, by reflecting twice with the reflecting mirror and the second reflecting mirror, the second reflecting mirror can be made to face the inside of the vehicle, that is, the driver. By viewing, the road surface projected on the reflecting mirror can be seen without any problem. Furthermore, by the twice reflection, the image of the second reflecting mirror can be seen as if seen through the movable plate, and the back side (outside of the vehicle) of the louver device can be visually recognized.

  Further, the louver device may be provided inside the viewing window, and the viewing window may be provided with viewing angle limiting means (14) for limiting the transmission of incident light from outside the vehicle and from above. . When a plurality of movable plates are closed, a portion that does not overlap each other will come out of the vehicle through the viewing window, and a part of the reflector or the second reflector is exposed in that portion. Depending on the incident angle of sunlight, there is a risk of reflecting reflected light to the vehicle behind and the pedestrians on the side, but the incident light from above is transmitted to the viewing window. By providing the viewing angle limiting means for limiting the incident light, the incident light that passes through the viewing window and reaches the reflecting mirror or the second reflecting mirror is limited, which causes dazzling of the rear vehicle or pedestrian due to the reflected light. Can be suppressed. Since this viewing angle suppression means limits the incident light from above, the incident light from the horizontal direction or from below can reach the mirror surface without being restricted, and the visibility to the side and bottom of the viewing window is ensured. The Here, “upward” means above the horizontal direction in the horizontal state of the vehicle and above the angle at which light incident on the second reflecting mirror in the horizontal direction is reflected in the closed state of the louver device. The viewing angle limiting means may be a viewing angle limiting film or the like.

  In addition, the reflecting mirror provided on the one movable plate and the second reflecting mirror provided on the other movable plate fully close the movable plates on each surface of the corresponding movable plate. It is good to be provided in the range which mutually overlaps so that it may not be visible from the vehicle inner side and the vehicle outer side. According to this, by setting the distance between the pivots of the plurality of movable plates, it is possible to arbitrarily set the overlapping amount of the overlapping portions in the fully closed state between the adjacent movable plates, and the reflecting mirror and the second mirror are included in the overlapping range. By providing the reflecting mirror, the reflecting mirror and the second reflecting mirror can conceal each other's reflecting surface in the fully closed state, and the reflected light not only on the outside of the vehicle but also on the inside of the vehicle in the fully closed state. Therefore, dazzling due to reflected light can be prevented not only for pedestrians but also for drivers.

  In particular, it is preferable that the movable plate is provided so that the opening and closing direction is the vertical direction, and the reflecting mirror is provided on a surface that faces downward when the movable plate is in a closed state. According to this, since the reflecting mirror faces downward in a closed state of the movable plate that does not require viewing from the viewing window, even if incident light from above enters the movable plate, the reflected light is directed upward. Since it is not reflected, the driver is not dazzled when the reflecting mirror is facing the inside of the vehicle, and a pedestrian outside the vehicle is not dazzling when the reflecting mirror is facing the outside of the vehicle. Alternatively, it is preferable that the reflecting mirror is provided on a surface of the movable plate that becomes the vehicle inner side when the movable plate is closed. According to this, since the reflecting mirror is directed into the vehicle in the closed state of the movable plate that does not require viewing from the viewing window, the sunlight is not reflected by the reflecting mirror, and the driver of the rear vehicle or walking It can prevent the glare with respect to a person etc. arising.

  The reflecting mirror may be formed by a mirroring process, and the same mirroring process as that of the reflecting mirror may be performed on the frame of the louver device. According to this, the same mirroring process is applied to the frame of the louver device together with the reflecting mirror, thereby enhancing the sense of unity between the reflecting mirror and the frame in the closed state of the movable plate that does not require viewing from the viewing window. This can improve the design. Here, the mirror surface treatment means that a mirror surface can be formed on the surface of the movable plate by plating or other film treatment. In the case of plating, electroplating, hot dipping, diffusion plating, vapor deposition plating, electroless Plating can be used.

  As described above, according to the present invention, by opening the plurality of movable plates and making them parallel to each other, it is possible to visually recognize the outside of the vehicle directly through the viewing window, and at a predetermined opening (angle). As a result, a portion near the vehicle exterior of the viewing window and close to the vehicle body can be visually recognized with a reflecting mirror, and a range that can be visually recognized through the reflecting mirror is added to a range where the outside of the vehicle can be viewed directly through the viewing window. It is possible to visually recognize a wide range with respect to the outside of the viewing window.

It is the perspective view seen from the diagonal left back of the motor vehicle as a vehicle to which this invention was applied. FIG. 2A is a schematic cross-sectional view taken along the line II-II in FIG. 1, and FIG. 2B is a schematic view of the interior surface of the door viewed from the line IIb in FIG. Shows the part. (A) shows a state where the movable plate is opened by a predetermined angle from the fully closed state, (b) shows a state opened parallel to the line of sight as viewed from the eye point of the driver's seat, and (c) shows a fully closed state. FIG. (A) shows the predetermined opening degree state of 2nd Embodiment, (b) is a figure which shows a fully closed state. (A) shows the predetermined opening state of the third embodiment, and (b) is a diagram showing a fully closed state. It is a figure which shows the predetermined opening state of 4th Embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an automobile as a vehicle to which the present invention is applied as seen from the diagonally left rear.

  FIG. 1 is an example in which a viewing window 3 is provided below the left door 2 of the vehicle body 1 in order to assist the visibility of the left side of the vehicle body when making a left turn in a right-hand drive vehicle. The viewing window is not limited to when turning left, and the rear lower viewing window is located below the rear panel (tailgate 4 in the illustrated example) as shown by the two-dot chain line in FIG. 5 may be provided, and although not shown, a right lower viewing window may be provided in the lower part of the right door on the driver's seat side. In the following description, an example in which the viewing window 3 is provided below the left door 2 as shown by the solid line in FIG.

  2A is a schematic cross-sectional view taken along the line II-II in FIG. 1, and FIG. 2B is the vehicle interior side of the door 2 seen from the line IIb in FIG. 2A. It is a figure which shows the principal part of the surface. The viewing window 3 may be formed of a transparent material such as glass, and may be fixed to the lower part and the front part of the left door 2 by, for example, snapping. A louver device 6 is disposed inside the viewing window 3 of the door 2.

  As shown in FIG. 2B, the louver device 6 includes a plate-like frame 7 attached to a panel portion in a range to be a lower portion of the window of the door 2 and a vehicle front portion of the frame 7. And a plurality of movable plates 8 provided. Each of the plurality of movable plates 8 is pivotally supported by a frame 7 so as to be rotatable about an axis in the vehicle longitudinal direction, and the opening degree is controlled by a motor 9 via a link mechanism (not shown) so as to open and close in synchronization. It has become. For example, in the case of visually recognizing the left side of the vehicle body 1 when turning left, the movable plate 8 can be opened by driving the motor 9 in conjunction with a left turn operation of a turn indicator (not shown). Further, when the left turn direction instruction is released, the motor 9 may be reversed to close the movable plate 8.

  Since each movable plate 8 performs the same operation, only a part (two adjacent plates) will be described as a representative in the following description of the movable plate 8. Unless otherwise specified, the other movable plates 8 have the same structure.

  FIG. 3 shows a side cross section of two adjacent movable plates 8 in the louver device 6. FIG. 3A shows a state in which the movable plate 8 is opened at a predetermined angle θ from the fully closed state (position Pc) in FIG. 3C, and FIG. 3B shows the driver in the driver's seat. FIG. 3C shows a fully open state in which the eye point 10 is opened in parallel with the line of sight as viewed from the eye point 10. The predetermined opening state may be an angle directed toward the eye point 10 in a state where a driver who becomes a standard model in the design of the automobile is seated. In addition, an angle adjustment function is provided in the motor control device as in the case of a known door mirror angle adjustment so that the driver can set an arbitrary angle. The state can be set.

  The movable plate 8 is provided with a reflecting mirror 11 formed of a plane mirror on the lower surface in FIG. The reflecting mirror 11 may be formed by plating using a material having high reflectivity, or may be formed by attaching a thin plate-like mirror. The pivot 8a for opening and closing the movable plate 8 is a midpoint position in the width direction of the movable plate 8 (the direction along the paper surface of the drawing) in the drawing, but is not particularly limited. For example, one end in the width direction It is good as a part.

  The predetermined opening degree of the movable plate 8 shown in FIG. 3A is set to an angle at which the image of the road surface portion 12 near the vehicle body 1 outside the vehicle reaches the eye point 10 via the reflecting mirror 11. When the outside of the vehicle is viewed through the louver device 6 in which the movable plate 8 is open in parallel with the line of sight as shown in FIG. 3B, a blind spot DS shown in FIG. If a curb or the like is in the blind spot DS when turning left, there is a risk that the rear wheel will ride.

  On the other hand, in the predetermined opening state of the movable plate 8 shown in FIG. 3A, the road surface portion 12 in the vicinity of the vehicle body 1 (corresponding to the blind spot DS) is reflected on the reflecting mirror 11, so that the louver device 6 The road surface portion 12 close to the vehicle body 1 that can be a blind spot DS when looking outside the vehicle from the gap between the movable plates 8 can be visually recognized, and the visibility of the portion that can become the blind spot DS when turning left in the illustrated example is improved.

  In this case, by optimizing the size and interval of the gaps between the movable plates 8, even if the width of each reflecting mirror 11 is small, it can be seen as a continuous large image, and the louver device 6 is provided. It is possible to see the image of the road surface portion 12 in a full range.

  When fully closed, the movable plate 8 is closed with the reflecting mirror 11 facing downward in the vehicle as shown in FIG. Thereby, since the reflection of the sunlight SL by the reflecting mirror 11 is directed downward and the sunlight SL is not reflected toward the driver, there is no problem that the reflecting mirror 11 becomes dazzling.

  Next, a second embodiment will be described with reference to FIG. In addition, about the part similar to the above, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted. In the second embodiment, the reflecting mirror 11 for visually recognizing the road surface portion 12 is provided on the upper surface in the predetermined opening state of FIG. 4A, and the movable plate 8 facing the reflecting mirror 11 is provided. A second reflecting mirror 13 made of a convex mirror is provided on the lower surface. In this case, the image of the road surface portion 12 close to the vehicle body 1 is reflected twice by the second reflecting mirror 13 and the reflecting mirror 11 and reaches the eye point 10.

  By reflecting twice in this way, the road surface portion 12 can be seen as if the lower movable plate 8 in the figure is seen through. Thereby, when the driver looks at the desired direction, the object in the desired direction can be displayed in the desired direction with the reflecting mirror 11, so that the driver can visually recognize the desired direction.

  In addition, a convex mirror is used as the second reflecting mirror 13, whereby a wider range of the road surface portion 12 can be visually recognized, and the visibility of a portion that can become a blind spot can be further improved. In this case, a plurality of reflecting mirrors 11 are formed by setting the corresponding second reflecting mirrors (convex mirrors) 13 to have different curvatures so that the ranges reflected on the adjacent reflecting mirrors 11 do not substantially overlap each other. One image can be projected as one mirror. In addition, by adjusting (different) the opening of each of the plurality of movable plates 8, an image having a continuity that can be recognized as one image is displayed on a large mirror composed of a plurality of reflecting mirrors 11. Is possible.

  In the illustrated example, the second reflecting mirror 13 is provided in the half of the movable plate 8 on the vehicle exterior side. However, the second reflecting mirror composed of a convex mirror over the entire width direction of the movable plate 8 is used. It may be provided.

  In addition, the reflecting mirror 11 and the second reflecting mirror 13 are provided on both the front and back surfaces of the movable plate 8, and the reflecting mirror 11 is provided on the entire surface that faces the outside of the vehicle when the movable plate 8 is fully closed. In the fully closed state, sunlight enters the reflecting mirror 11 through the viewing window 3. For this reason, there is a possibility that a passerby outside the vehicle may feel the reflected light reflected by the reflecting mirror 11 of sunlight SL.

  In contrast, as shown in FIG. 4B, the louver device 6 is provided inside the viewing window 3, and sunlight SL outside the vehicle enters the louver device 6 through the viewing window 3. Therefore, it is preferable to attach a viewing angle limiting film 14 as a viewing angle limiting means to the outer surface of the viewing window 3. The viewing angle limiting film 14 may be a known film that does not allow incident light from a predetermined direction to pass therethrough, and is provided so that the limiting direction is incident from above. As a result, the sunlight SL from above is prevented from passing through the viewing window 3, and the reflected light of the sunlight SL as shown by the two-dot chain line in the figure does not occur even when the reflecting mirror 11 faces the outside of the vehicle. Therefore, dazzling for passersby is prevented. The viewing angle limiting film 14 allows incident light from below to pass therethrough, and the road surface portion 12 can be visually recognized without any problem as shown in FIG.

  Further, in the fully closed state, as shown in FIG. 4 (b), the second reflecting mirror 13 that faces the inside of the vehicle is covered with the movable plate 8. The incident sunlight is not reflected by the second reflecting mirror 13, and the driver is not dazzled. In this manner, the visual window 3 and the louver device 6 are arranged in this order from the outside of the vehicle, thereby preventing glare to pedestrians and the like due to reflection of sunlight SL from outside the vehicle and reflection of sunlight SL in the vehicle. Due to the above structure, the anti-glare prevention measures for the driver can be easily and suitably performed.

  Next, a third embodiment will be described with reference to FIG. In addition, about the part similar to the above, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted. In the third embodiment, as shown in FIG. 5A, the reflecting mirror 11 is provided on the upper surface of the movable plate 8 in about half the width direction of the movable plate 8. Then, as shown in FIG. 5B, the reflecting mirror 11 and the second reflecting mirror 13 face each other in the fully closed state and are shielded from the outside by the respective movable plates 8. .

  Thereby, even if sunlight SL from the outside of the vehicle is incident, the incident light is only incident on a portion of the movable plate 8 facing the outside where the reflecting mirror 11 is not provided, and the reflected light passes outside the vehicle. There is no dazzling for people. Moreover, the incidence of sunlight SL from the inside of the vehicle is only incident on the portion facing the vehicle in which the second reflecting mirror 13 is not provided, and the reflected light does not become dazzling for the driver.

  As an example of the predetermined opening degree of the movable plate 8, in the above-described embodiment, an example of an angle at which the surface facing the vehicle inner side is downward is shown. However, the inclination direction of the movable plate 8 at the predetermined opening degree may be reversed. An example thereof will be described as a fourth embodiment with reference to FIG. In addition, about the part similar to the above, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.

  As shown in FIG. 6, the reflecting mirror 11 is provided on the surface facing the upper side of the movable plate 8 at the predetermined opening, and the second reflecting mirror 13 is provided on the surface facing the lower side. The image of the road surface 12 is reflected by the second reflecting mirror 13 and reflected on the reflecting mirror 11, and the optical path from which the image reflected on the reflecting mirror 11 reaches the eye point 10 is the same as in the third embodiment. This is effective when the look-down angle (corresponding to θ in the figure) from the eye point 10 to the louver device 6 is small (shallow).

  In this way, it is possible to deal with any case where the positional relationship between the eye point 10 and the louver device 6 is high, and it is possible to provide a highly versatile louver device.

  Further, when there is no need for visual recognition at the time of a left turn or the like, the movable plate 8 is fully closed in order to prevent the movable plate 8 from being fully viewed through the visual window 3 from outside the vehicle. However, for example, in the case of the first embodiment shown in FIG. 3, the reflecting mirror 11 faces the inside of the vehicle. The reflecting mirror 11 may be plated as described above, and in that case, the surface of the frame 7 facing the inside of the vehicle may be further plated. As a result, a sense of unity is created when the movable plate 8 is closed, and the aesthetics of the louver device 6 are improved. In the case of plating treatment, the reflectance may be inferior to that of a glass mirror, but it can function sufficiently as visibility.

  As mentioned above, although an example of the louver device 6 based on this invention was shown, it is not restricted to the said illustration example, Various forms can respond | correspond. In addition, the above-described measures for preventing glare on pedestrians of reflected light are provided when the louver device 6 is provided corresponding to the rear lower viewing window 5 provided at the lower part of the rear door 4 as shown in FIG. It is also effective for preventing glare caused by reflected light with respect to the driver of the vehicle behind.

  Further, the opening / closing direction of the movable plate 8 is not limited to the above-described embodiment. In the above-described embodiment, the pivot 8a of the movable plate 8 is provided in the direction extending in the front-rear direction of the vehicle. . By setting the pivot 8a of the movable plate 8 in the vertical direction, the rear portion of the viewing window 3 outside the vehicle can be viewed like a side mirror (door mirror). Further, the pivot 8a of the movable plate 8 can be provided so as to be tilted backward with respect to the vehicle body 1, and in this case, the portion of the visual recognition window 3 that is the rear and lower part outside the vehicle can be visually recognized.

  Moreover, although the said embodiment demonstrated as what provided the reflecting mirror 11 in all the movable plates 8 provided as the louver apparatus 6, it is not necessary to provide the reflecting mirror 11 in all the movable plates 8, and as a part The reflecting mirror 11 may be provided on at least one movable plate 8. For example, if the area of one movable plate 8 is large enough to be visually recognized as the reflecting mirror 11, the reflecting mirror 11 is provided only on that one movable plate 8, and the other movable plate 8 is reflected. The mirror 11 may not be provided. Further, in the case of the use of reflecting twice, the reflecting mirror 11 is provided on one of the opposed movable plates 8 and the second reflecting mirror 13 is provided on the other. In this case, the reflecting mirror 11 and the second reflecting mirror 13 are provided. It is sufficient to provide at least one or more sets of the reflecting mirror 11 and the second reflecting mirror 13 as one set with the reflecting mirror 13.
