Description

  The present invention relates to a vehicle door mirror structure, and more particularly to an electrically retractable door mirror structure.

  In recent years, it has become mainstream to employ a door mirror to visually recognize the rear of a vehicle. Moreover, in order to improve the visibility behind the vehicle, a technique of incorporating a camera in the door mirror is also employed (see, for example, Patent Document 1).

  In the door mirror structure described in Patent Document 1, a built-in camera is attached to the tip of the door mirror main body. The door mirror body is opened when the vehicle travels at a low speed below a predetermined value, and the door mirror body is stored when the vehicle travels at a high speed above the predetermined value.

  Here, when driving at low speed, the occupant visually recognizes the rear of the vehicle with the mirror part of the door mirror body, while at high speed, the rear of the vehicle is visually recognized by an image displayed on the monitor in the vehicle compartment via the camera. Yes.

  However, since the conventional door mirror structure is switched from visual recognition using the door mirror to visual recognition using a camera while the vehicle is traveling, there is a risk that visibility at the time of switching may be reduced. That is, for example, when the vehicle traveling speed is 80 km / hour and it takes 2 seconds to switch, the vehicle travels about 44 m during the switching, which may reduce visibility.

  Therefore, an object of the present invention is to provide a vehicle door mirror structure that can maintain high visibility behind the vehicle.

  According to a first aspect of the present invention, a vehicle door mirror structure includes a base plate that is attached to the vehicle body and extends along the vehicle front-rear direction, and a camera that is fixed to the rear end of the base plate and visually recognizes the rear of the vehicle. And a door mirror main body pivotally supported by the base plate, wherein the door mirror main body rotates and opens when the vehicle traveling speed is a predetermined value or less. The door mirror body is configured to store when the speed is equal to or higher than a predetermined value.

  In the vehicle door mirror structure according to claim 2 of the present invention, a cover that protects the door mirror body when the door mirror body is stored at the front end of the base plate is pivotally supported. To do.

  In the vehicle door mirror structure described in claim 3 of the present invention, the cover is formed such that the vertical height gradually increases from the front end toward the rear end.

  According to the vehicle door mirror structure described in claim 1 of the present invention, since the camera is fixed to the rear end of the base plate, the camera can visually recognize the rear of the vehicle at both low speed and high speed. It can be carried out. Therefore, since it is not necessary to switch between visual recognition by the door mirror main body and visual recognition by the camera, high visibility can be maintained.

  Further, when traveling at low speed, visibility can be performed by both the door mirror main body and the camera, so that visibility can be further improved.

  According to the vehicle door mirror structure described in claim 2 of the present invention, since the cover for protecting the door mirror main body is provided, the door mirror main body is prevented from being scratched even when an obstacle such as a stone hits the door mirror main body. The appearance quality is also improved. Further, since the wind does not directly hit the door mirror body when the vehicle is traveling, wind noise can be suppressed.

  According to the vehicle door mirror structure of the third aspect of the present invention, since the vertical height of the cover gradually increases as it goes rearward, the wind during vehicle travel can be rectified by the cover, and the wind Cutting noise can be further reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of a door mirror according to an embodiment of the present invention as seen from an oblique direction, and shows a state in which a door mirror main body is opened. FIG. 2 is a perspective view of the door mirror of FIG. 1 and shows an intermediate stage in which the door mirror main body is stored. FIG. 3 is a perspective view of FIG. 1 viewed obliquely from the front.

  As shown in FIGS. 1 and 2, the door mirror 1 according to the present embodiment is rotatable to the base plate 3 fixed to the vehicle body side, the camera 5 fixed to the rear end of the base plate 3, and the front end of the base plate 3. And a cover 7 that is pivotally supported by the shaft.

  The base plate 3 is fixed to the vehicle body side (for example, the front end of a door or the like). When viewed from the side of the vehicle, it is formed in a substantially triangular shape, and is formed such that the vertical height gradually increases from the front to the rear.

  The front end of the base plate 3 is formed on a front end support portion 9, and a cover 7 is pivotally supported on the front end support portion 9 as will be described later. Further, a rear end support portion 11 that is bent outward in the vehicle width direction is formed at the rear end, and is substantially L-shaped in plan view when the base plate 3 is viewed from above. Two cameras 5 and 5 are attached to the upper and lower portions of the rear end support 11 toward the rear of the vehicle. Further, a tongue piece 13 is protruded vertically on the outer side in the vehicle width direction of the rear end support portion 11, and a door mirror main body 15 of the door mirror 1 is pivotally supported on the tongue piece 13.

  The door mirror main body 15 includes a mirror portion 17 that projects a landscape behind the vehicle, and a housing portion 19 that holds the mirror portion 17.

  The front end of the cover 7 is pivotally supported by the front end support portion 9 of the base plate 3 and can rotate in the vehicle width direction with the front end as an axis. Further, it is formed in a shape that covers the door mirror body 15. Specifically, as shown in FIG. 2, the side surface portion 21 whose vertical height gradually increases from the front end toward the rear end, and the upper flange portion that is bent and extends from the upper end edge and the lower end edge of the side surface portion 21. 23 and the lower flange portion 25, and the side surface portion 21, the upper flange portion 23 and the lower flange portion 25 are formed in a substantially U-shaped cross section. A notch 27 is formed at the rear end of the side surface portion 21, and a lid portion 29 is pivotally supported on the notch 27. When the lid 29 is rotated and closed, the notch 27 is closed.

  Next, for the door mirror 1 according to the present embodiment, a procedure for switching the door mirror main body 15 from the opened state to the retracted state will be briefly described.

  First, as shown in FIGS. 1 and 3, since the door mirror main body 15 protrudes outward in the vehicle width direction, the occupant directly touches the mirror portion 17 of the door mirror main body 15 when the vehicle traveling speed is a low speed traveling below a predetermined value. By looking, the rear of the vehicle can be visually recognized with the naked eye. Further, since the image captured from the camera 5 is displayed on the monitor in the vehicle interior, the passenger can also visually recognize the rear of the vehicle with the interior monitor.

  Next, when the vehicle traveling speed rises to a predetermined value or higher and the vehicle travels at a high speed, the cover 7 is rotated and opened outward in the vehicle width direction with the front end as a rotation axis, as shown in FIG. Then, while the door mirror body 15 is folded toward the front of the vehicle, the cover 7 rotates and closes toward the inner side in the vehicle width direction.

  Then, as shown in FIG. 4, the door mirror main body 15 is stored and the cover 7 is also closed. In this state, an occupant can visually recognize the rear image of the vehicle on the indoor monitor of the image captured from the camera 5. The cover 29 of the cover 7 is open in the state of FIG. 1, but is closed in the state of FIG.

  Note that the present invention is not limited to the above-described embodiments, and various modifications can be made based on the technical idea of the present invention.

  For example, although two cameras 5 are provided on the upper and lower sides of the base plate 3, the number is not limited to two and may be one or three or more.

It is the perspective view which looked at the door mirror by embodiment of the present invention from the back diagonally toward the front, and has shown the state where the door mirror main part opened. It is a perspective view of the door mirror of FIG. 1, and has shown the intermediate | middle stage in which the door mirror main body is stored.
