Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION This invention relates to for example a van or a large vehicle side electrical components within the built vehicle stowable outside mirror with mirror provided electrical components in mirror used in such as an automobile .

[0002]

2. Description of the Related Art Conventionally, as an outside mirror used for vehicles such as wagons and large vehicles, a mirror supporting member mounted on a vehicle body and a mirror having a lower end horizontally rotatably held by the mirror supporting member are known. There is a retractable type that includes a stay and a side mirror mounted on the mirror stay, and stores the mirror stay by rotating the mirror stay inside the vehicle width when not in use.

In this retractable mirror, a mirror member mounted in a mirror body (housing) of a side mirror is provided so as to be tiltable in an arbitrary direction, and a drive motor (electric component) for tilting and driving the mirror member is provided in the mirror body. It is conceivable to arrange them inside. In addition, it is also considered that frost or the like adheres to the surface of the mirror member in winter or the like,
In order to melt the frost, it is conceivable to incorporate an electric component such as a heater in the mirror body.

[0004]

A harness for supplying power to such an electric component is connected to a power source such as a battery in a vehicle body and is wired along a mirror member and a mirror stay. It is desirable to prevent the harness from being greatly twisted during horizontal rotation.

[0005] The present invention is for an object to provide an electrical component in the built <br/> vehicle stowable outside mirror with a mirror along the above requirements.

[0006]

In order to achieve this object, the present invention provides a mirror supporting member mounted on a vehicle body, a mirror stay having a lower end horizontally rotatable by the mirror supporting member, and A retractable outside mirror for a vehicle with a mirror having a built-in electric component including a side mirror mounted on a mirror stay, an electric component mounted in the side mirror, and a harness connecting the power source of the vehicle body and the electric component. A lower end of the mirror stay
Attach a cover covering the mirror to the mirror support member,
A notch is provided in the cover to allow horizontal rotation of the stay,
Move the harness between the mirror support member and the cover.
And a mirror stay, and the mirror
Connect the lower end of the stay and the straddling portion that straddles the mirror support
End of the straddling portion on the side of the mirror stay
In the direction in which the rotation center line of the mirror stay extends.
The mirror stay is held at the lower end, and the straddling portion is extended in the direction in which the rotation center line of the mirror stay extends.
In the state, the vicinity of the end of the straddling portion on the mirror support member side is set to the front.
It is characterized in that it is a retractable outside mirror for vehicles with a built-in mirror for electric components held between the cover and the mirror support member .

[0007]

According to this structure, when the mirror stay is horizontally rotated when the side mirror is moved between the storage position and the use position, the harness is not largely twisted and slightly around the straddling portion. It will be a twisting motion.

Next, in FIG. 4 and FIG.
A position slightly protruding from the vehicle width to the side of the vehicle body 1 is defined as a use position (a), and a position where the side mirror 7 is rotated inside the vehicle width of the vehicle body 1 is defined as a storage position (b). The operation of the retractable outside mirror for a vehicle will be described. still,
1, 5, and 6, BL is a body line on one side of the vehicle body 1.

In such a configuration, the side mirror 7
When the drive motor 10 is operated to move the drive motor 10 from the use position (a) to the storage position (b), the rotation of the drive motor 10 causes the gear reduction mechanism 31, the clutch 33, and the driven gear 23 to rotate.
Is transmitted to At the initial stage of rotation of the driven gear 23, only a small play between the driven gear 23 and the mirror support shaft 22 causes only the driven gear 23 to rotate. At this time, the mirror support shaft 22 is raised by the action of the cam plate 21 and the ball 24, and the fixed locking plate 41 of the mirror positioning mechanism 40 is moved.
And the rotation body 42 is unlocked.

When the drive motor 10 is further rotated, the driven gear 23 and the flat surfaces (not shown) of the mirror support shaft 22 are engaged with each other, and the mirror support shaft 22 is rotated, and the mirror stays 5, 6 and the side mirror 7 are rotated. Is rotated to the storage position (b).

Conversely, when the drive motor 10 is operated, the side mirror 7 is moved to the use position (a). With such rotation of the mirror stays 5, 6,
Although the harness 62 is rotated so as to slightly twist the straddling portion 62b, the harness 62 is not unnecessarily twisted.
