Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote control mirror device.

In particular, the present invention relates to a mirror device in which a mirror body is supported by a mirror body.

This type of mirror is used as a remote control rearview mirror for automobiles, but conventionally, a drive unit (motor, electromagnet, etc.) attached to the mirror body is electrically actuated to control the displacement of the mirror body. Alternatively, a configuration is adopted in which the mirror body is displaced by transmitting the power of the drive source using a link mechanism, a combination of gears, or the like.

However, the former technology requires a driving part such as a motor, which is disadvantageous in terms of installation time and cost.On the other hand, the latter technology requires a complicated link mechanism and gear mechanism, which reduces workability and cost. In addition to this, there is also the problem that troubles may occur during power transmission.

Therefore, a remote control mirror device was developed that solved the above-mentioned problems.

This remote control mirror device is known, for example, from Japanese Patent Application Laid-open No. 143.23/1983 and British Patent No. 1.38.
4.845, a mirror body and a mirror body that supports the mirror body are arranged in a tiltable manner in a mirror housing, and the mirror body is tilted back and forth in the mirror housing. An operating section that is operable and rotatable along an axis in its operating plane is provided, and an operating force transmission means is interposed between the operating section and the mirror body, so that the operating section can be operated back and forth. By rotating the operating section, the mirror body is tilted on the vertical axis passing through the center of tilting of the mirror body, and on the left and right axis passing through the center of tilting of the mirror body.

In such a remote control mirror device,
Since the amount of operation of the operating section and the amount of tilting of the mirror body differ depending on the direction in which the mirror body is tilted, it is necessary to provide means for absorbing changes in the relative distance between the operating section and the mirror body in the operating force transmission means.

The above-mentioned remote control mirror device is
The operating force transmission means is provided with a sliding mechanism in which members such as pins provided on the mirror housing are slidably engaged with members such as elongated holes and elongated grooves also provided on the mirror housing, and the sliding movement of this sliding mechanism is provided. This absorbs changes in the relative distance between the operating section and the mirror body depending on the application.

However, when a sliding mechanism is provided, play occurs due to the gap that exists in the sliding part of the sliding mechanism, and as a result, the amount of operation of the operating section and the amount of tilting of the mirror body do not match accurately, making it difficult to achieve accurate operation accuracy. is not obtained.

Further, during long-term use, the sliding portion of the sliding mechanism wears out, causing the mirror body to shake and the stability of the mirror body itself to be easily impaired.

An object of the present invention is to provide a remote control mirror device that provides accurate operation precision and stability of the mirror body itself.

The inventor focused on the difference between the operating amount of the operating section and the tilting amount of the mirror body when transmitting the swinging force (during the swinging operation of the operating section), and created a gap between the operating section and the mirror body. , 2 which can only swing the connecting part which is separated from the mirror housing.
The inventors have devised that by interposing and holding the mirror body using a hinge mechanism, it is possible to absorb changes in the relative distance between the operating section and the mirror body without using a sliding mechanism.

An example of implementing the present invention will be described below with reference to the drawings.

In this example, the present invention is applied to a remote control type rearview mirror for an automobile, and is an example in which the present invention is embodied by forming many parts using a resin material.

That is, the remote control mirror device of the present invention has the following features:
As shown in the drawing, a mirror body 1 and a mirror body 2 that supports the mirror body 1 are tiltably disposed in a mirror housing 3, and are movable back and forth and located in the operating plane. An operating section 4 rotatable about an axis X, and an operating section 4 connected to a mirror body 2 via two hinge structures 5 and 6.
The mirror body is tilted by the connecting part by operating the operating part 4 back and forth along a vertical axis passing through the tilting center of the mirror body 2, and rotated to pass through the tilting center of the mirror body. It is designed to be tilted along the left and right axes.

Here, the operating plane is a plane on which the operating section 4 operates in directions E and F in the figure, that is, a plane on the paper in FIG.
is on this plane.

A more detailed explanation of the structure of the illustrated example is as follows.

First, as shown in FIG. 1, the mirror body 1 is supported by the mirror body 2 by being gripped by the mirror body 2 at its periphery.

Therefore, when the mirror body 2 is tilted, the mirror body 1 is also tilted integrally with it.

By press-fitting the ball member 31 attached to the inner surface of the mirror housing 3 into the seat 21 formed by recessing the back surface of the mirror body 2, the mirror body 1 and the mirror body 2 are inserted into the mirror housing 3. Arranged so that it can be tilted.

In the mirror housing 3 of this example, a part 3a surrounding the mirror body 2 etc. and a part 3b to which the operating part 4 is attached are formed separately, and both parts 3a and 3b are fixed and integrated by a screw 32. However, if there are no problems in mold production or molding, there is no need to separate both 3a and 3b, and they may be molded integrally.

(In this example, the mirror housing 3 is made of synthetic resin, especially ABS.
It is carved out of resin.

The mirror body 2 is also made of resin, and in particular PP resin is used).

The mirror body 2 is tilted and angled within the mirror housing 3 as described above, thereby changing the angle of the mirror body 1 to adjust the mirror. The mirror body 2 is connected to the mirror body 2 via the hinge structure 6 made of a resin thin film part and another hinge structure 5 that is connected to the shaft 42 at the end of the operating section 4 and the bearing 23 on the hinge structure 6. The spherical portion 41 is attached to the compartment side portion 3b of the mirror housing 3 so as to be tiltable in any direction.

The operating portion 4 has a lever shape as shown in the figure.

To install the spherical part 41 of the operation part 4 in the mirror housing 3, set the washer 91 in the mirror housing 3, apply the spherical part 41 to the washer 91, as shown in FIG. 5 from the opposite side, that is, from the passenger compartment side. By arranging a spring 92 like this,
Tighten screw 93 to hold it in place.

When tightening the screw 93, the torque of the ball portion 41 can be adjusted by applying force.

At this time, a coil spring 94 may be interposed in the screw 93 if necessary.

Further, the washer 91 may be originally integrated with the mirror body 3 to reduce the number of parts.

Furthermore, as shown in FIG. 3A, a bracket 96 having a space 95 for fitting the ball part 41 is attached to the mirror housing 3 with a screw 97, and the torque adjustment of the ball part 41 is performed by using a space 95 for fitting the ball part 41. By tightening the screw 98 and nut 99 placed in the front part, the ball part 4 is tightened.
The tightening of the space 95 can also be achieved by adjusting the tightening of the space 95 with the space 95 disposed.

This example also simplifies the configuration because only the bracket 96 needs to be attached as a separate component.

Furthermore, as shown in FIG. 4, a simple configuration may be adopted in which an undercut portion 33 is formed in a shape that narrows toward the passenger compartment, thereby enhancing the shape of the fitting space 34 of the bulb portion 41.

The inner end of the mirror housing 3 of the operation section 4 is the shaft 42 as described above, which is received by the bearing 23 formed in the connection section 22 with the mirror body 2, and this structure creates a hinge structure. 5 is in full force.

A small screw 23' is disposed on the bearing 23 as necessary, so that a predetermined torque can be generated in the hinge structure 5.

The connecting portion 22 and the mirror body 2 are connected via the hinge structure 6, and in this example, the corresponding portion of the mirror body 2 is formed into a thin film portion of the flesh, thereby forming a hinge. This too is taking shape.

In this example, since a resin material is used for the mirror body 2, the characteristics of the resin are fully utilized, and the hinge structure 6 can be formed easily and inexpensively, and stable operation can be obtained. .

However, it goes without saying that the hinge structure 6 may be formed by attaching a separate component, such as a hinge, to the mirror body 2 instead of being integrated with the mirror body 2.

The hinge structure 6 has a knob 4 in order to adjust the visibility in the left and right direction.
When the knob 3 is operated in the direction of arrow E or F in Fig. 1, it functions as a hinge, but when the knob 43 for adjusting the vertical field of view is operated in the direction of arrow K or L in Fig. 2, the hinge functions. The movement of the knob 43 is transmitted to the mirror body as a tilting movement along the left and right axis without performing any function.

In this way, the hinge structure 6 functions as a hinge by itself in one direction, and in the other direction, the mirror body 2 and the connecting part 22 are made to be similar to an integrated rigid body, so that the hinge structure 6 can be used in an extremely simple manner. This structure allows the mirror body 2 to freely tilt.

The hinge structure 6 of this example is vertically shaped as shown in FIG. This is because it is configured so that it can be bent only in response to tilting.

Furthermore, the present invention is configured such that by rotating the operating section 4, the mirror body 2 can be tilted in a direction different from the tilting direction via the hinge structure 6.

That is, in the illustrated example, the mirror body 2 is moved by tilting the operating portion 4 and bending the hinge structure 6 as described above.
Since it is possible to tilt the mirror body 2 in the left and right directions, the mirror body 2 can be tilted in the vertical direction by rotating the operating section 4.

As is clear from FIG. 2, the mirror body 2 is directly tilted in the vertical direction by rotating the tip knob 43 of the operating section 4, and the spherical member 31 of the mirror body 2
Tilt around the center.

In the illustrated example, the mirror body 2 has a fulcrum part 7, and the mirror housing 3 receives the fulcrum part 7 to guide sliding in one direction and to prevent movement in other directions. is provided with a guide portion 8 which is locked and thereby allows the fulcrum portion 7 to act as a fulcrum.

Specifically, a protrusion is provided on the outer tip of the mirror body 2, and this is used as the fulcrum part 7.

On the other hand, the corresponding portion of the mirror housing 3 is provided with a pair of opposing wall portions 81 and 82, and grooves 83 are formed in both walls 81 and 82, and these are used as the guide portion 8.

Therefore, the fulcrum part 7 moves freely in the A direction along this groove 83, but the movement in the B direction perpendicular to this is due to the wall parts 81,
82.

In such a case, the fulcrum portion 7 remains at one point within the guide portion 8 and serves as a fulcrum.

The fulcrum portion 7 may be integrated with the mirror body 2 or may be attached separately.

The same applies to the guide portion 8 of the mirror housing 3.

In the illustrated example, the guide portion 8 is located at the left end in FIG. 2, but it is located at a position 8a in FIG. A pair of shaft support structures may also be provided.

Alternatively, as shown in 8b and 8c in the same figure, they may be provided at one or both of the upper and lower positions centering on the ball member 31.

What is shown in FIG. 6 is an example in which the guide portion 8 is formed at one position 8a in FIG. 2 described above.

This forms a cutout 24 in the connecting portion 22 of the mirror body 2, and there are two wall portions 81 integral with the mirror housing 3,
A guide portion 8 consisting of 82 is positioned, and a fulcrum portion 7 consisting of a substantially cylindrical projection is provided from the mirror body 2, with the A direction being the sliding direction and the B direction being the locking direction.

In addition, as described above, the mirror body 2 is provided with the seat 21 and the ball member 31 is press-fitted therein, but a bracket similar to that used to explain the pivoting of the operating part 4 in FIG. 3 may be used. The mounting structure may be a general manual type mounting structure.

In addition, the operating unit 4 in the illustrated example has a tip knob 43, a ball portion 41,
Although the shaft 42 is made of resin and the shaft 44 is made of metal, any other material may be used.

In the figure, reference numeral 10 denotes a vehicle body. For example, this mirror device can be placed on the vehicle body near the glass near the driver's seat so that the driver can manually operate it.

With the above configuration, the angle of the mirror body 1 can be adjusted very easily and reliably as described below.

First, when it is desired to displace the mirror body 1 in the left-right direction, that is, in the direction of C or the mouth in FIG. 1, it is sufficient to tilt the operating section 4 up and down, that is, in the direction of E or F in the figure.

For example, if you move the operation unit 4 upward in the figure (direction E),
The shaft 42 of the hinge structure 5 moves downward in the figure (in the G direction), the connecting portion 22 is also pushed down in the downward direction (in the H direction), and the mirror body 2 is similarly pushed down through the hinge structure 6.

Therefore, using the ball member 31 as a fulcrum, the mirror body 2 is deflected in the direction of arrow C, and the mirror body 1 is also tilted.

At this time, the fulcrum part 7 of the mirror body 2 slides on the guide part 8, but at the same time, it is guided by the guide part 8 so that the mirror body 2 does not tilt.

On the other hand, when the operating portion 4 is moved downward (direction F), the mirror body 2 is tilted in the direction of the arrow by the opposite operation described above.

Next, in order to displace the mirror body 1 in the vertical direction, that is, in the directions of arrows I and J in FIG. 2, it is sufficient to rotate the operating section 4 and move it in the direction L in FIG.

For example, when the operating portion 4 is rotated in the direction, this movement is directly transmitted to the mirror body 2, and the mirror body 2 is tilted upward in one direction.

At this time, the fulcrum part 7 is locked to the guide part 8 and rotates in the direction of arrow M as a fulcrum.

The remote control mirror device of the present invention in this embodiment includes a connecting portion 22 that is separated from the mirror housing 3 and a connecting portion 2 that is separated from the mirror housing 3 without using a sliding mechanism.
Changes in the relative distance between the operating section 4 and the mirror body 2 are absorbed by the two hinge mechanisms 5 and 6 that can only swing, which are interposed and held between the operating section 4 and the mirror body 2. can do.

Therefore, there is no play in the sliding portion of the sliding mechanism, and accurate operation accuracy can be obtained.

Moreover, there is no wobbling of the mirror body 2 due to wear of the sliding parts, and stability of the mirror body 2 itself can be obtained.

As is clear from the above embodiments, the remote control type mirror device of the present invention has a connection part that is separated from the mirror housing between the operation part and the mirror body.
Since it is interposed and held using two hinge mechanisms that can only swing, it is possible to absorb changes in the relative distance between the operating section and the mirror body without using a sliding mechanism. Operational precision and stability of the mirror body itself can be achieved.

Note that although the illustrated example has many additional effects and advantages depending on its specific configuration, the present invention is not limited only to this example.
