Description

[Detailed description of the invention] [Industrial field of application] The present invention provides a mirror equipped with a remote-controlled driving device, such as a door mirror for an automobile.
This relates to a remote control switch for tilting up, tilting down, tilting to the right, and tilting to the left.

[Prior art]

As a switch means for operating the remote control mirror, for example, as shown in FIG. 7, there are a push switch 1u for upward tilt operation, a push switch 1d for downward tilt operation, and a push switch 1 for left tilt operation.
It is also conceivable to arrange the push switch 1r for right tilt operation, but in this way the switch 4
Arranging the pieces increases the number of man-hours required for installation, resulting in higher costs and also gives a cluttered, unrefined design.

In order to solve these problems, a remote control switch shown in FIG. 8 can be considered.

A structure is conceivable in which a push button 3 (functionally a double-acting push button and shaped like a push plate) having a planar width is elastically supported within the case 2. Inside the case 2, four sets of switch mechanisms (not shown) are provided. When the upper side 3u of the push button 3 is pressed, the upward tilt operation switch among the four switch mechanisms is closed. Similarly, the vicinity of the lower side 3d, the vicinity of the left side 3l,
The structure is such that when the right side 3r is pressed, the switch mechanisms for tilting downward, tilting to the left, and tilting to the right are respectively closed.

The above remote control switch (No. 8)
In Figure), if you accidentally push the center part m,
There is a risk that two or more of the four built-in switch mechanisms will close, causing the mirror drive circuit (not shown) to shoot.

Further, for example, if a portion slightly closer to the center than the upper side 3u is pressed too strongly, a similar phenomenon (shoot) may occur.

In order to eliminate the above-mentioned problem (the possibility of shooting), a push button having a flat width is supported elastically, and a plurality of sets of switch mechanisms are arranged to face the push button, and the pressing surface of the push button is specified. In a remote control mirror switch having a structure in which a specific switch mechanism among the plurality of sets of switch mechanisms opens and closes when the push button is pressed, a protrusion is provided inside near the center of the push button, and the push button is opposite to the protrusion. If the fulcrum member is fixed to the switch case and the push button is structured to be able to tilt around the tip of the protrusion, the push button having the above planar width will see-saw around the fulcrum. There is no risk that two sets of switch mechanisms will be activated at the same time.

The above configuration is currently being applied for separately by the present applicant.
61-112754) (hereinafter referred to as the earlier application), Fig. 4 is a front view showing one embodiment of the earlier application;
The figure is a sectional view thereof, FIG. 5 is an exploded perspective view of the above embodiment, and FIG. 6 is an enlarged view of a portion of FIG. 1.

As shown in FIG. 4, a push button 5 is elastically supported on the case 4.

5u is an operation position display mark attached near the upper side of the push button 5, and 5d, 5l, and 5r are also operation position display marks.

The four switch mechanisms 6u, 6d, 6l,
6r is arranged.

As shown in Fig. 5, operation position display mark 5
Opposing the insides of u, 5d, 5l, and 5r (lower surfaces in the figure) are push rods 6u _-1 and 6, respectively.
d _-1 , 6l _-1 , and 6r ₁ are provided, and their rod-shaped portions are connected to guide tubes 9u and 6r 1 integrally connected to the base 9, respectively.
9d, 9l, and 9r.

Coil spring 6u _-2 , 6d _-2 , 6l _-2 , 6r _-2
are push rods 6u _-1 , 6d _-1 , 6l _-1 , 6 respectively
It is pushing up r _-1 .

As shown in FIG. 3, a base plate 8 is provided below the push rod 6d _-1 via a disc plate 6d _-3 shaped like a disc spring, and a contact piece 8d is provided on the base plate 8. 10 is a back cover, and 11 is a connector.

As shown in FIG.
d _-1 is provided, and an annular contact piece 8d _-2 is provided around it. Belleville spring-shaped disk plate 6d _-3
is placed on the annular contact piece 8d ₂ facing and spaced apart from the center contact piece 8d _-1 , and is positioned by the tongue piece 6d _-31 .

When push rod 6d _-1 is pushed down in the direction of arrow P,
The disk plate 6d _-3 is bent and electrically connected to the central contact piece 8d _-1 .

The configuration of the switch mechanism 6d has been described above, but the configurations of the switch mechanisms 6u, 6l, and 6r are also similar to this. 7 (FIGS. 3 and 4) is a slide switch for switching between operation of a mirror (for example, a door mirror) provided on the left side of the vehicle body and operation of a mirror provided on the right side of the vehicle body. Reference numeral 7 shown in FIG. 5 is an opening in which the slide switch 7 is provided.

As shown in FIG. 3, a protrusion 5a is integrally provided on the inner surface of the central portion of the push button 5, and a platform-shaped fulcrum 9a is integrally provided on the base 9 to face the protrusion 5a. c is the clearance dimension.

The first switch configured as above is the third switch.
In the figure, even if the central portion of the push button 5 is pressed in the direction of arrow P', the push button only moves in parallel in the direction of P' by the clearance dimension c.

After the protrusion 5a and the fulcrum 9a abut, the push button 5 can only perform seesaw movement around the fulcrum 9a. Therefore, it is impossible for the two opposing switch mechanisms, ie, the switch mechanisms 6u and 6d, or the switch mechanisms 6l and 6r, to be pushed and closed at the same time.

[Problem that the invention attempts to solve]

To configure the electric circuit for freely tilting the remote control mirror up, down, left, and right, we need two double-pole single wires for each of the up, down, left, and right tilts. Requires a throwing switch function. In the switch of the earlier application mentioned above, (see Fig. 5) there are two disk plates each on the upper, lower, left, and right sides 6u _-3 , 6d _-3 , 6l _-3 , 6r _-3
, and are configured to simultaneously push each set of two switch mechanisms. For example, the push rod 6l _-1 in Figure 5 has two rods 6l _-11 and 6l _-12.
They are connected together by a head 6l _-13 so as to support them in parallel.

As a result, the two rods 6l _-11 and 6l _-12 move up and down in conjunction with each other, and the two disc plates 6l _-3 and
6l _-3 are opened and closed at the same time.

In FIG. 4, 6l _-11 and 6l _-12 are two parallel rods of the switch mechanism 6u.

The push button 5 is supported like a seesaw at its center M, so when the mark 5u is pressed, for example, it tilts around the axis and the two rods 6u- ₁₁ and 6u _-12 of the switch mechanism 6u move. The upward tilting operation is performed by being pushed evenly.

Also, if you press near the upper left corner of pushbutton 5,
The pushbutton 5 tilts about the axis α-α to actuate both the switch mechanisms 6u and 6l simultaneously. (Note: For example, if two switch mechanisms whose operations cannot be compatible, such as an upward tilting switch mechanism and a downward tilting switch mechanism, are turned on at the same time, a shot will occur. , compatible operating switch mechanisms can be turned on simultaneously without any problem).

However, as can be easily understood from FIG.
When operating the switch mechanisms 6l and 6u by tilting them around, it is very difficult to make the rods 6l _-11 and 6l _-12 slide evenly. However, unless the rods 6l _-11 and 6l _-12 slide evenly, the mirror will not tilt to the left.

The present invention has been made in view of the above-mentioned circumstances, and is an improvement on the switch for remote control mirrors according to the earlier application, and provides a remote control mirror in which a pair of rods connected in parallel can slide evenly without tilting. The purpose is to contribute to improving the operational reliability of remote control mirror switches.

[Means for solving problems]

An outline of the idea behind this invention, which was created to achieve the above purpose, will be described below.

In Figure 5, _two
In order to smooth the sliding of the book rods 6l _-11 , 6l _-12 , push button 5 and push rods 6l _-1 ,
An elastic member is interposed between each of 6u _-2 , 6d _-2 and 6r _-2 . When carrying out the above idea, it is desirable that the elastic member is configured so as to come into contact with both ends of the head 6l _-13 and push it.

Based on the above idea, the remote control mirror switch of the present invention has a specific structure for applying it to practical use. Applied to a remote control mirror switch having a structure in which a plurality of sets of switch mechanisms are arranged to face each other, and when a specific part of the pressing surface of the push button is pressed, a specific switch mechanism among the plurality of sets of switch mechanisms is operated to open or close, (a) A projection is provided inside near the center of the push button, and a fulcrum member facing the projection is fixed to the switch case, so that the push button can tilt around the tip of the projection. (b) a base member is provided between the plurality of sets of switch mechanisms and the push button, and a push rod is interposed between each of the plurality of sets of switch mechanisms and the push button; (c) the base member is provided with a push rod; A cylindrical guide member is integrally attached through the guide member and the push rod is slidably fitted therein, and (d) a member for connecting the two push rods is formed by forming a set of two of the push rods. (e) an end of the push rod facing the push button protrudes from the connecting member in a spherical shape; (g) providing an elongated plate-shaped member made of an elastic material that comes into contact with the surface facing the push button of the connecting member; (h) providing the plate-shaped member made of an elastic material with the A hole is provided to fit into the spherical protrusion of the push button, and a platform-shaped protrusion that abuts the push button is provided at both ends of the plate-like member made of an elastic material.

According to the above configuration, the see-saw movement of the push button is transmitted to both ends of the connecting member of the push rod via the projection of the elastic member, so that the flexure of the projection of the elastic member is applied to the pair of connected push rods. The pressing force is equalized, and
Allow the pair of push rods to slide smoothly.

Moreover, since an elastic pressing force is applied to both end members of the member connecting the pair of push rods, the pair of push rods can easily slide evenly.

Furthermore. After the protrusion of the elastic member is bent in the compression direction, the abutment seat abuts the spherical protrusion;
Reliable pressing is performed near the end of the pressing stroke.

〔Example〕

Next, one embodiment of the remote control mirror switch of the present invention will be described.

This embodiment is an example in which the present invention is applied to the embodiment of the remote control mirror switch of the prior application mentioned above.

In this embodiment, the push button 5 shown in FIG.
The configuration of case 4 and "base 9 and the components drawn below this" is the same as the embodiment of the previous application (FIG. 5).

In this embodiment, FIG. 1 shows the structure of the tail in which the pusher plate faces the pusher rod. The components shown in FIG. 1 correspond to the parts shown in FIG. 5 (springs 6l _-2 and 6d _-2 are omitted).

The push rod 6l _-1 in this example (Fig. 1) consists of two parallel rods (push rods) 6l _-11 and 6l _-12 .
and a head 6l _-13 which connects these to form an integral structure.

The upper end portions of the rods 6l _-11 and 6l- ₁₂ protrude spherically above the head 6l _-13 , and the spherical projection 6
l _-14 and 6l _-15 are formed.

On the other hand, the inner surface of the pushbutton 5 has a protrusion 5a.
is provided, and the spherical projections 6l _-14 , 6
Table-shaped abutment seats 5l _-14 and 5l _-15 are provided opposite l _-15 .

An elongated plate-shaped elastic member 12l is provided between the push rod 6l _-1 and the push button 5, which abuts the head 6l _-13 . This elastic plate 12l is made of a rubber elastic material rather than a so-called spring elastic material, and is formed into a plate shape corresponding to the head 6l _-13 . The projections 12l _-1 and 12l _-2 are provided, and the holes 12l _{-14 and 12l -15 are provided to allow the spherical projections 6l -14 and 6l -15} to pass through.

12u, 12r, and 12d are elastic plates having the same shape and size as the holes 12l of the elastic plate 12l, respectively.

The elastic plate 12l is superimposed on the head 6l _-13 of the push rod 6l _-1 , and the spherical protrusions 6l _-14 , 6
l _-15 respectively to the holes 12l _-14 and 12 of the elastic plate 12l
l _-15 and the spherical protrusions 6l _-14 and 6l _-15 are opposed to the abutment seats 5l _-14 and 5l _-15 .

A cross section in this state is shown in FIG. This sectional view is drawn along a plane including the center lines of the rods 6l _-11 and 6l _-12 .

In Fig. 2, when the central part of the pair of rods 6l _-11 and 6l _-12 is pressed as indicated by arrow Ps, both rods 6l _-11 and 6l _-12 are pushed down equally without any problem. to slide.

As shown by the arrow Pc in the same figure, when the rod 6l _-11 is pushed at a location closer to the center of both rods, the pedestal projection 6l _-2 closer to the arrow Pc will move away from the other pedestal projection 6l. Receives a large pressing force compared to _-1 .

The pedestal projection 6l _-2 that has received a large pressing force is compressed more than the pedestal projection 6l _-1 that has received a small pressing force. In this way, a pair of rods 6
The pressing forces applied to l _-11 and 6l _-12 are averaged,
The push rod 6l _-1 including the rods 6l _-11 and 6l _-12 can be slid smoothly.

When the push button 5 is further pressed down, the rubber elastic platform projections 6l _-1 and 6l _-2 are compressed, and the spherical projections 6l _-14 and 6l _-15 contact the abutment seats 5l _{-14 and} 6l -15, respectively.
It comes into contact with 5l _-15 and receives pressure. In this way, at the beginning of the downward stroke of the push button 5, the pressing force is balanced by the resilient members 6l _-2 , 6l _-1 , and the rods 6l -11, 6l _-1
6l _-12 slides smoothly, and at the end of the rolling stroke, the contact seats 5l _-14 and 5l _-15 rigidly press the spherical protrusions 6l _-14 and 6l _-15 to ensure the switch mechanism is activated. Activate it.

The above description of this embodiment has been about the push rod 6l _-1 for tilting the mirror leftward, but the push rod 6u _-1 for upward tilting and the push rod 6d for downward tilting shown in FIG. _-1 and the rightward tilting push rod 6r _-1 have the same configuration, and can provide similar actions and effects.

[Effect of idea]

As explained above, the remote control mirror switch of the present invention does not lose the advantage of the remote control mirror switch of the prior application (shot prevention), and in addition, the pair of rods connected in parallel are connected to the push plate. It slides smoothly as the switch is pushed, ensuring reliable switch operation.
