Abstract

PURPOSE:To provide an outer mirror unit that is capable of securing a rearview range even at a time when a side mirror is in a retreating position shifted inwards in the car width direction from the original position. CONSTITUTION:An outer mirror unit 1 consists of a stay 2 extending outwards in the car width direction, a side mirror 3 attached to a tip of this stay 2, and a case 4 with a built-in mechanism where a base end of the stay 2 is inserted into, and making the stay 2 expandable. When this side mirror 3 is shifted to a retreating position, length of the stay 2 is contracted to some extent by a mechanism in the stay 2. At this time, as the side mirror 3 is parallelly shifted, a driver is able to secure a rearview range even at a time when the side mirror 3 is shifted to the retreating position.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable outer mirror device for a vehicle, and more particularly to a vehicle outer mirror device for obtaining a rear view even when the vehicle is moved from a normal position.

[0002]

2. Description of the Related Art Since an outer mirror device of a vehicle usually projects outward from the body in the vehicle width direction, it may be an obstacle when passing a narrow road. Especially trucks,
In the outer mirror device 40 (FIG. 4) in which the side mirror 42 is attached to the stay 41 that extends outward in the vehicle width direction as used in buses and one-box vehicles, the side mirror 42 largely protrudes outward in the vehicle width direction. Therefore, it is often necessary to move the side mirror 42 from the normal position to the retracted position inward in the width direction of the vehicle body when passing each other as described above.

In this type of outer mirror device 40, since the stay 41 is swingable with respect to the body A, by swinging the stay 41, the side mirror 42 shown by the dotted line in FIG. Move it to the inner retracted position.

[0004]

However, if the side mirror 42 is moved to the retracted position, it is possible to pass the side mirror 42, but the position of the mirror surface changes greatly, so that the vehicle driver uses the side mirror 42. It is often difficult to check the condition behind the vehicle. Therefore, the driver
While checking the condition of the car body and the surroundings directly with the naked eye, they pass each other. At this time, the confirmation on the passenger side becomes particularly difficult.

The present invention has been made in view of the above problems, and provides an outer mirror device for a vehicle, which can provide a rear view even when the mirror is in the retracted position inwardly moved in the vehicle width direction from the original position. The purpose is to do.

[0006]

In order to achieve the above object, on the premise of an outer mirror device for a vehicle in which a side mirror is attached to a stay extending outward in the vehicle width direction, the side mirror has an original position and an original position. A retracted position that is moved inward in the vehicle width direction from the position, and when the side mirror takes the retracted position, the mirror surface of the side mirror is at a certain point, and the vehicle operation with respect to the point is performed. The visual confirmation ensuring means for moving the stay and / or the side mirror is provided so that the angle of incidence of the line of sight of the hand is substantially equal to the angle formed by the normal line of the mirror at the point and the side surface of the vehicle body.

Further, the stay can be expanded and contracted on the premise of an outer mirror device of a vehicle in which a side mirror is attached to a stay extending outward in the vehicle width direction, and the expansion and contraction of the stay causes the side mirror to move to the original position and the original position. The retracted position moved inward in the vehicle width direction from the position.

[0008]

In the present invention having the above-mentioned structure, the visual confirmation ensuring means enables the side mirror to be retracted even when the side mirror is in the retracted position.
When looking at the side mirror from the vehicle driver, the side surface of the vehicle is always visible in the side mirror. Also, the stay can be expanded and contracted, and the expansion and contraction of the stay causes the side mirror to
Since the original position and the retracted position that is moved inward in the vehicle width direction from the original position can be taken, even when the side mirror is moved to the retracted position, the mirror surface of the side mirror is in the original position. It is kept parallel to the mirror surface of the side mirror when it is opened.

[0009]

EXAMPLES Examples of the present invention will be described in detail below. FIG. 1 shows an outer mirror device 1 according to one embodiment of the present invention.
The outer mirror device 1 includes a stay 2 extending outward in the vehicle width direction, a side mirror 3 attached to the tip of the stay 2, and a case 4 into which a base end portion 2a of the stay 2 is inserted. It The case is attached to the front fender panel P and the inner panel I at the front end of the body A of the vehicle. As a result, the outer mirror device 1 is fixed to the body A of the vehicle.

The side mirror 3 moves in parallel as the stay 2 expands and contracts in the vehicle width direction. For example, when the stay 2 contracts in the direction indicated by the arrow in FIG. 1, the side mirror 3 moves in parallel from the position indicated by the solid line to the position indicated by the dotted line. The stay 2 may be expanded and contracted by any method, but for example, the method shown in FIG. 2 can be considered. In this method, the motor M is placed inside the case 4.
The reduction gear train G and the tubular body 5 that is rotationally driven by the reduction gear train G are provided. A nut-shaped member 6 that rotates integrally with the cylinder 5 is attached to the inside of the cylinder 5.
Then, the base end portion 2a of the stay 2 on which the screw screw is formed is screwed.

Motor M driven by switch 7
The rotation of is transmitted to the cylindrical body 5 by the reduction gear train G.
The nut-shaped member 6 mounted inside the tubular body 5 is
Rotates integrally with. As a result, the base end portion 2a of the stay 2 screwed to the nut-shaped member 6 linearly moves in the axial direction of the stay 2 (left-right direction in FIG. 2), and the stay 2 also moves in the same direction.

A non-circular portion 2b having a non-circular cross-sectional shape such as an oval is formed adjacent to the base end portion 2a of the stay 2. Since the non-circular portion 2b is fitted in the non-circular hole 4b formed in the case 4, the stay 2 and the case 4 do not rotate with respect to each other. Therefore, the rotation of the nut-shaped member 6 moves the stay 2 in its axial direction without rotating the stay 2.

As a concrete configuration of the switch 7, a circuit as shown in FIG. 3 can be considered. This circuit has three positions: stop, extension and storage. As described above, in this embodiment, when the vehicles pass each other,
When it is necessary to move the side mirror 3 from the original position (the position of the side mirror in the normal running state) to the retracted position where the side mirror has moved inward in the vehicle width direction, the switch 7 is moved in the retracted direction, By shortening the length of the stay 2, the side mirror 2 is moved to the retracted position (for example, the position indicated by the dotted line in FIG. 1) so that the vehicle can pass each other.
At this time, since the side mirror 3 linearly moves inward in the vehicle width direction, the amount of protrusion of the side mirror 3 outward in the vehicle width direction can be effectively reduced. After the passing, the switch 7 is operated in the extension direction to return the side mirror 3 to the original position.

The above embodiments are merely examples and do not limit the present invention. The present invention can be variously modified and modified within the technical scope described in the scope of claims. For example, in the above embodiment, the stay extends outward in the vehicle width direction, but the stay extending obliquely forward of the vehicle body may be expanded and contracted.

Further, like the stay of the conventional outer mirror device, the stay can be swung with respect to the vehicle body, and at the time of passing or the like, the stay is swung to take the retracted position, the swing angle is read, and the read amount is read. Based on the above, a predetermined calculation is performed by a microcomputer or the like, the side mirror is automatically rotated by an amount corresponding to the swing angle, and the mirror surface of the side mirror when the side mirror takes the retracted position is At one point, the angle of incidence of the line of sight of the vehicle driver with respect to the one point is made substantially equal to the angle formed by the normal line of the mirror and the side surface of the vehicle body at the one point, and the driver is set at the original position and the retracted position of the outer mirror device. May provide a similar rear view.

[0016]

[Effect] According to the present invention described in detail above, when the side mirror is moved to the retracted position, the side mirror is not folded, and moreover, in the almost same state as when the side mirror was in the original position, Since the field of view near the side of the vehicle body can be secured, even in difficult driving situations such as passing on a narrow road, it is possible to drive while checking the side and rear sides of the vehicle body.
