Abstract

PURPOSE:To enable the simultaneous movement of right and left rear view mirrors by reducing the angle of horizontal adjustment in the rear view mirror far from the driver's seat at a specified ratio with respect to the angle or horizontal adjustement in the rear view mirror close thereto. CONSTITUTION:Resistances RL and RR are connected respectively between right- left switching contacts and electromagnetic clutches 11 of right and left linkage switches 8L and 8R to set the angle ratio of the angle of horizontal adjustment in right and left rear view mirrors 1L and 1R. For example, the resistances RL and RR are set at RL>RR. For an example, the ratio between them is put at RL:RR=10:9 and the speed ratio between the motor ML for driving the rear view mirror 1L far from the driver's seat and the motor MR for driving the right rear view mirror 1R close to the driver's seat is put at about 9:10. In this manner, setting of the resistance values of the resistances RL and RR different properly enables the changing angles of horizontal adjustment in the right and left rear view mirrors 1L and 1R at a specified ratio.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a pair of left and right rearview mirrors that can adjust the horizontal field of view of the mirrors by remote control.
This invention relates to a rearview mirror device for an automobile.

(Prior art) Conventionally, there has been a one-way visibility adjustment mechanism and a vertical visibility adjustment mechanism, each driven by a motor.
A remote-operated bank mirror device is well known that adjusts the visibility of the rearview mirror by controlling the on-shift of the motor φ11 from the inside of the vehicle. (Jitsukai Showa 57 L5!35
(See Publication No. 43).

By the way, in conventional rearview mirror devices of this type, the left and right rearview mirrors are remotely controlled separately, so the driver can control the rearview mirror by, for example, sliding the driver's seat or changing drivers. Even when the viewpoint position of the vehicle is changed, the horizontal field of view of the bank mirror must be adjusted individually in accordance with the viewpoint change, which poses a problem in that the adjustment operation is complicated.

(Objective of the Invention) The present invention provides remote control of the left and right rearview mirrors at the same time, and which one is based on one rearview mirror (close to normal driving 1 case ([1+1 bank mirror)].
In order to adjust the horizontal field of view, it is an object of the present invention to provide a bank mirror device for an automobile having a structure that ensures the horizontal field of view of the bank mirror of excretion force.

(Structure of the Invention JIi,) In order to achieve the objective, in the present invention, the horizontal field of view of the mirror is adjusted by remote control.
＋ The left and right moon bank mirrors with the left and right irises are equipped with the left and right rearview mirrors. Operation 11
``1-'' The horizontal adjustment angle of the rearview mirror on the side far from 1θ is reduced by a predetermined ratio to the horizontal adjustment angle of the rearview mirror on the side closer to operation 1θ. The feature is that a ratio adjustment means is provided to adjust the ratio.

(Effects of the Invention) According to the present invention, it is possible to operate the left and right rearview mirrors at the same time, and when adjusting while looking at one rearview mirror, it is possible to adjust the left and right rearview mirrors at the same time. Therefore, by ensuring horizontal visibility of the bank mirrors of both swords at the same time, it is possible to perform operations easily.

(Example) Hereinafter, embodiments of the present invention will be explained in a simple manner.

As shown in FIG. .

The horizontal field of view of the IR is from the eye point of the driver sitting in the driver's seat 3 behind the steering wheel 2.
1 as a reference, the driver has adjusted the 7 mirrors IL and 1R so that they can see directly to the rear.

Now, if a driver with a different eye point returns or slides the driver's seat 3 backwards, the eye point will change, so the left and right mirrors 11-
, IR eliminates good visibility directly behind the vehicle.

For example, if the eye point is changed from El) 1 to the most extreme position 1-: P 2 The opening angles with respect to the rear direction are △θL and △e, respectively.
[Increase by <. Therefore, in order to see directly behind the changed eye point E l) 2,

I-) Almost equal to the ratio of angles θL and θR looking at 3,
When measured on a certain actual vehicle, this ratio was eL20R
It became 10.

[Rearview mirror by changing the eye point] The angle adjustment of L and IR (for the horizontal direction) can be done by setting the adjustment ratio as above. This means that simultaneous adjustments can be made.

Next, the angle adjustment mechanism of the left and right rearview mirrors IL and IR will be explained.

Contact points 6L and 6R are used to select the vertical direction (vertical field of view of the mirror) and the left and right direction (horizontal field of view of the mirror). Selection switch A L, 7R is connected! For the interlocking contact 6, the two left and right interlocking selection switches 81.8R, which are linked to the switching of the individual selection switches 7L7 and 7I, are used to prevent backflow. They are connected in parallel via 9t.

The switching contacts of the left independent selection switch '71-+ and the interlocking selection switch 8L are connected via an electromagnetic clutch 11 (ILE, to be exact, a 2-launch thread/ite fill) for switching between the vertical direction and the horizontal direction.

Next, the angle of the bank mirror shown in Figures 3 to fjSG is 7i scale I! □;

As shown in Figure 3 regarding the uniformity of the left rearview mirror,
Inside the inner case 13 supported within the mirror case 12, there is a drive motor 11. = I l, along with the electromagnetic clutch/reduction gear device 14 and the electromagnetic clutch/reduction gear device]4, the vertical adjustment gear 15 and the horizontal adjustment gear 1G are selectively driven by the drive motor MJ.

As shown in the figure, when the force meshing portion 4'A' 25 meshes with the sun gear 23 of the reduction gear device 18, which is often used in the downward direction of force, the rotation of the sun gear 23 is caused by the rotation of the planet gear 27, 28.
Ring gear 2 through! ] 1 and is decelerated, and the vertical adjustment gear 15 integrated with the ring A and gear 2 is driven.

Then, when the current in the electromagnetic coil 21 is reversed by 11ψ, the clutch plate 20 is displaced to the left in the figure against the spring force of the coil link 30 due to the reversal of the magnetic field, and the clutch plate 20 is displaced to the left in the figure, causing the mesh to move northward. When the member 2G meshes with the sun gears 2 and 4 of the left-right adjustment gear device 11, the rotation of the sun gear 24 is transmitted to the ring gear 33 via the planet 1 gears 31 and 32; The left/right direction adjustment gear 16 is also driven.

As shown in FIG. 4, when the vertical adjustment gear 15 is driven, as shown in FIG. The rearview mirror 11-, which is connected to the shaft provided at the base of the fan-shaped gear part (134), is swung around the pivot 35 in the vertical direction. Since the eyepoint heights for the right bank mirrors IL and JR are the same, the adjustment ratios may be the same.

The right rearview mirror 11 near the driver's seat is also provided with basically the same adjustment mechanism as above.

In that case, the reduction ratio of the reduction gear device 10 for lateral adjustment of the left rearview mirror 1L far from the driver's seat is compared to the reduction ratio of the reduction gear device 10 for lateral adjustment of the right rearview mirror IR near the driver's seat. The ratio of the left and right adjustment angles of the left and right rearview mirrors IL, IR may be approximately 9:10.

Further, as shown in FIG. 3 for the left rearview mirror 11-5, the length IR of the swinging arm when adjusting the right rearview mirror IR in the left-right direction is compared to the length IL of the swinging arm when adjusting the right rearview mirror 11-5 in the left-right direction.

In addition, in the electric circuit diagram shown in FIG. 2, an interlocking contact 6C is provided in addition to the left and right individual switching contacts 6L and 6R.
For example, the left rearview mirror IL may be linked only when the right rearview mirror drive contact near the driver's seat is selected and adjusted.

In addition, as a single operation means, in FIG. 2, the independent/interlocking changeover switch 6 is used to
