The present invention is characterized by comprising interlocking means for sliding the mirror wiping member back and forth with respect to the mirror surface in conjunction with the operation of the mirror housing driving means.

[Effect]

When the motor for raising and lowering the mirror housing is activated, the mirror wiping member automatically slides against the mirror surface.

〔Example〕

Examples will be described with reference to the drawings.

In FIG. 1, a mirror base 1 is immovably held by a door body (not shown), and a mirror housing 2 is rotatably supported with respect to the mirror base 1. As shown in FIG. 2, a gear 9 is fixed to the mirror base 1 and is held in a non-rotating state. For convenience, the center 10 of the gear 9 is referred to as a fulcrum, and the mirror housing 2 is rotatable around the fulcrum 10.

When the mirror housing 2 is erected at the solid line position shown in FIG. 1, the door mirror is in use, and in this state, a rear view is obtained through the mirror 12. On the other hand, when the door mirror is not in use, the mirror housing 2 is folded down and stored at the imaginary line position.

Inside the mirror housing 2, a motor 3 shown in FIG. 3 and a mirror housing driving means 100 for converting the rotation of the motor into a raising and lowering movement of the mirror housing 2 are provided.

The mirror housing driving means 100 is composed of a gear system as illustrated in the figure, and when the motor 3 mounted on the support member 13 (FIG. 2) rotates, the worm 4, the worm wheel 5, the gear 6, and the gear 7 are rotated.
Gear 8A is configured to rotate via A and gear 7B. In addition, the worm wheel 5 and the gear 6 are coaxially integrated, and the gear 7A and the gear 7B
are also integrated, and are rotatably supported by the support member 13 and the bottom wall of the mirror housing 2 together with the gear 8A. In FIG. 1, illustration of the gears 7A and 7B is omitted for convenience in order to avoid cluttering the drawing.

When gear 8A rotates, gear 8B integrated with it rotates.
rotates. Then, gear 8B is meshed with gear 9, and since gear 9 is held in a non-rotating state, gear 8B rotates and changes its meshing position with gear 9, and revolves around gear 9. do. In other words, it functions like a planetary gear in a planetary gear mechanism.

After all, in FIG. 3, the gear 8B is
The mirror housing 2 revolves around the fulcrum part 10 on a revolving locus with a radius R, and accordingly, the mirror housing 2 is rotated around the fulcrum part 10.

In FIG. 1, when the gear 8B rotates clockwise and revolves clockwise around the gear 9, the mirror housing 2 is closed from the upright position to the down position. By switching the rotation direction of the motor 3, the mirror housing 2 can be rotated from the upright position to the laid down position, or conversely, from the laid down position to the upright position. In FIG. 1, the reference numeral 14 is an adjustment mechanism for changing the direction of the mirror 12.

The mirror housing driving means 100 thus achieves the function of converting the rotation of the motor 3 into the raising and lowering movement of the mirror housing 2.

As described above, the door mirror is electrically driven, and such a drive configuration has been known for some time.

A feature of the present invention is that a mirror wiping member such as a wiper blade is slid back and forth on the mirror surface in conjunction with the operation of the mirror housing drive means.

Gear 9 includes gears 4 and 6 in addition to gear 8B.
As shown in the figure, a gear 15 is engaged, and this gear 15 is rotatably mounted on a support member 16 fixed to the mirror housing 2 so as to be orthogonal to the rotational axis of the gear 9. Note that FIG. 6 shows the peripheral components of the gear 9 shown in FIG. 2 as viewed from the direction of arrow a.

The gear 15 has a gear portion formed in the circumferential direction on one surface, and a rivet pin 1 on the other surface.
7 is firmly planted, and this stud pin 17 is attached to the crank arm 18.
It fits into a long hole 18a (FIG. 5) provided in the.
The crank arm 18 is swingable around the axis of a shaft 19 to which the base end thereof is integrally attached.

As shown in FIG. 7, a mirror 12 is provided on the front surface of the mirror housing 2, and a wiper blade 21, which is an example of a configuration of a mirror wiping member for wiping the mirror surface, is in contact with the mirror 12.

As shown in FIG. 4, the aforementioned shaft 19 is rotatably attached to the side of the mirror housing 2, and the base end of the wiper mounting rod 22 is fixed to the outer shaft end of the shaft 19. A wiper holder 23 is attached to the free end of this mounting rod 22, and the above-mentioned wiper blade 21 is fixed to this wiper holder 23. Note that the wiper holder 23 is frictionally coupled to the free end via a stop pin 24.

Now, to describe the operation of this embodiment, the mirror housing 2 is in the upright position in use as shown in FIG. In this state, the crank arm 18 occupies the position shown in FIG.

FIG. 8 schematically shows the wiper blade drive configuration in this state, and the wiper blade 21 is connected to the mirror 12 as shown in FIG.
occupies the lower position. In addition, in each figure after FIG. 8, illustration of the wiper holder 23 is omitted for convenience.

Here, when the motor 3 shown in FIG. 3 rotates,
As described above, the gear 8B revolves around the gear 9 while rotating, and at this time, the mirror housing 2 begins to rotate clockwise in the drawing about the fulcrum 10 in FIG. 8A. In other words, it starts turning from the standing position to the lying position.

When the mirror housing 2 rotates, the gear 15 meshing with the gear 9 rotates together with the mirror housing 2 in the direction of the arrow. Then, since the gear 9 is held in a non-rotating state, the gear 15 that meshes with it starts rotating in the direction of the arrow in FIG.

Due to this rotation, the crank arm 18 begins to pivot counterclockwise around the center of the shaft 19 via the stud pin 17. Then, since the wiper mounting rod 22 shown in FIG. 2C rotates in the same direction, the wiper blade 21 begins to move upward while sliding against the mirror surface of the mirror 12.

9A shows the halfway state when the mirror housing 2 is turning toward the folded position, FIG. 9B shows the halfway turning state of the crank arm 18, and FIG. 9C shows the halfway moving state of the wiper blade 21. There is.

FIG. 10A shows a state in which the mirror housing 2 has been rotated to near the folded position, and in this rotated position,
The crank arm 18 occupies the position shown in Figure B, and the wiper blade 21 occupies the position shown in Figure C. At this position, one end of the wiper blade 21 touches the upper corner of the mirror 12.

FIG. 11A shows a state in which the mirror housing 2 is stored in the folded position, and in this state, the crank arm 18 occupies a position that has been turned to the uppermost position as shown in FIG. 11B. On the other hand, as the wiper mounting rod 22 further rotates from the position shown in FIG. 10C, the wiper blade 21 gradually rotates clockwise around the stop pin 24.
When the mirror housing 2 is retracted, the entire wiper blade 21 moves to the uppermost position, as shown in FIG. 11C, and in this state, the mirror 12
Water droplets adhering to the surface are uniformly wiped away.

When mirror housing 2 is stored,
The wiper blade 21 is in the position shown in FIG. 11C, but when the mirror housing 2 is automatically pivoted from the retracted position to the upright position for use, the above-mentioned action is performed in reverse. While moving downward, the wiper blade 21 is placed in the position shown in FIG. 8C when the mirror housing 2 is completely erected. Even during this turning, mirror 1 of mirror housing 2, which has been stored until now,
If there are water droplets or dust attached to the mirror surface 2, or if the mirror surface is cloudy, these will be removed or the cloudy state will be resolved. Therefore, when the vehicle is in use, a clear rear view can be obtained.

When the mirror 12 gets water droplets while the car is running, the wiper blade 21 will slide back and forth on the mirror surface when the mirror housing 2 is temporarily retracted and raised to the use position again. Water droplets on the mirror surface can be removed instantly.

Note that, as shown in FIG. 10C, the wiper blade 21 is frictionally coupled to the wiper mounting rod 22 via a stop pin 24, and is movable around this stop pin 24.
The wiper blade 21 is moved from the oblique position to the position shown in FIG.
As shown in the figure, it can be turned horizontally and the mirror surface can be completely wiped away without waste.

Here, when the gear 15 meshing with the gear 9 rotates, the crank arm 18 provided in the mirror housing 2 transfers this rotational movement to the mirror housing 2.
This converts the vertical movement of the wiper blade 21 provided outside, and other means may be used as long as it achieves this type of function.

Here, it has already been mentioned that the mirror housing drive means 100 shown in FIG. As this occurs, the gear 15 shown in FIG. 4 meshes with the gear 9 and rotates around it together with the mirror housing 2.

Gear 15, rivet pin 17, crank arm 18, shaft 1
9 and the wiper mounting rod 22, etc., ultimately function as interlocking means for sliding a mirror wiping member such as the wiper blade 21 back and forth with respect to the mirror surface in conjunction with the operation of the mirror housing drive means. will be achieved.

Such a configuration eliminates the need for a dedicated motor for driving the mirror wiping member, and also eliminates the need for a switch or electrical wiring for operating the mirror wiping member.

In the end, the configuration will be further simplified,
At the same time, it becomes possible to further reduce costs.

In addition, in rainy weather when the vehicle is not driving, raindrops tend to adhere to the mirror surface, but these can be easily removed by simply operating the mirror housing 2 when the vehicle is not driving or when the vehicle is driving. It is safe and provides clear visibility even in rainy weather.
Moreover, since only the wiper blade 21 is located on the mirror surface, the aesthetic appearance is not spoiled.

[Effects of the invention] According to the configuration of the invention, there is no need for a dedicated motor for driving the mirror wiping member or its wiring, so it is possible to further simplify and reduce the cost of this type of device. In addition, since there is no need for installation space for a dedicated motor, etc., the mirror housing does not become bulky.
