Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a side mirror adjustment switch device for an automobile that is inserted and connected to a control circuit of the mirror in order to electrically adjust the mirror surface tendency from inside the vehicle.

Recently, most passenger cars, from large luxury cars to small consumer cars, have come to be equipped with electric side mirror adjustment devices that can be operated from inside the car.

Since the side mirror adjustment device adjusts the mirror surface by driving the mirror with a motor, it is equipped with two control circuits for the left side mirror and the right side mirror, and also has a power supply switch connected to this control circuit. There are usually two control levers located in front of the driver's seat.

However, due to the need to reduce the installation area of this type of device, a switch device that can adjust the left and right mirrors with a single operating lever has been developed and is already in use today. This type of switch device is constructed by disposing a slide block for selecting the control circuit for the left mirror or the right mirror, and another slide block for adjusting the mirror surface tendency of each mirror on a single terminal board.
However, according to such a switch device, it is necessary to enable independent movement of the two slide blocks, and also to arrange a circuit selection terminal in addition to a mirror-like adjustment terminal on one terminal board. Not only has the switch device itself become larger, but its structure has also become considerably more complicated.

Therefore, the present invention solves the above-mentioned drawbacks of the conventional device by providing one slide block driven by a single operating lever between two terminal boards.

In addition, each of the sliding terminals 7a and 7b is fixed to both ends of the spring 8 in advance, and in that state, each of the internal holes 6
It is convenient to insert it into b.

As is clear from FIG. 2, the slide block 6 has two parts fixed parallel to the switch body 1.
It is slidably installed between two printed circuit boards (terminal boards) 9 and 10.

On the other hand, the printed circuit board 9 is shown in FIG.
The printed circuit board 10 has the terminal configuration shown in the figure).
In the terminal structure shown in FIG. 11 (or FIG. 14), these terminals are fixed so that their terminal surfaces face each other. The printed circuit board 9 located at the front (hereinafter referred to as the front board) is held between the support plate 4 and the frame-shaped spacer 11, and the spacer 11 is held between the printed circuit board located at the rear (hereinafter referred to as the rear board). )10. Note that a through hole 9a for the operating lever 2 is provided in the center of the front board 9.

As shown in FIG. 7, the spacer 11 is a frame made of an insulating material with its four corners folded inward, and has two folded portions 11 formed on the four sides.
The movement of the slide block 6 is guided between the positions a and a. Also, in Figure 7,
12a and 12b are conductive springs that electrically connect the front board 9 and the rear board 10, and serve to supply power from the rear board 10 to the front board 9. Note that FIG. 7 is a sectional view taken along line H--H in FIG. 2.

The operation of the switch device configured as described above will be explained below.

1 and 2, the left mirror is in the selected state, and in this state, the slide block 6 is in the displaced position shown in FIG. 7, and the sliding terminals 7a and 7b are in the 10th position.
× of the printed circuit boards 9 and 10 shown in the figure and FIG.
It is located at the mark. Therefore, when the operating lever 2 is pushed upward (upward in FIG. 1) in this state, the lever 2 pivots clockwise in FIG. In order to move it, the operating state shown in FIG. 9 is achieved. In such an operating state, the sliding terminals 7a, 7b are displaced to the positions indicated by solid circular marks in FIGS. 10 and 11. Sliding terminals 7a, 7
When b is displaced to this position, current flows through the left mirror motor ML and solenoid SL in the direction of the solid line arrow, so the interlocking gear is attracted by the solenoid SL, so the motor ML is connected to the mirror interlocking system. At the same time, the mirror surface of the mirror is adjusted upward.

In this embodiment, the interlocking system that adjusts the horizontal direction of the mirror and the motor are connected by a gear pulled back by a spring force, and the interlocking system that adjusts the vertical direction of the mirror is the same as described above. It is assumed that the gear is connected to the motor when it is attracted and displaced by the solenoid (or electromagnet).

Next, when the operating lever 2 is pushed down (upper part of Figure 1), the slide block 6 is moved upward (upper part of Figure 2).
Move to. Therefore, the sliding terminals 7a and 7b are
The left mirror motor ML and solenoid SL are displaced to the positions indicated by the dotted circular marks in Figures 0 and 11.
A current flows in the direction of the dotted arrow. Therefore, the mirror surface of the left side mirror is adjusted downward.

When the operating lever 2 is pressed and tilted to the top left in FIG. 1, the slide block 6 moves to the top left in FIG.
It is displaced to the position indicated by the solid line triangle mark in the figure and FIG. 11. Therefore, in this case, no current flows through the solenoid SL, but a current flows through the motor ML in the direction of the dotted arrow, so that the mirror surface of the left mirror is adjusted to the left.

When the operating lever 2 is pressed and tilted to the right in FIG. 1, the slide block 6 moves to the right in FIG. displaced to the position, and therefore,
A current flows through the motor ML in the direction of the solid arrow, adjusting the mirror surface of the left mirror to the right.

In addition, FIG. 12 shows the left mirror control circuit showing the above-mentioned switch switching, and in FIG. 12a,
The switch closed position indicated by a solid line indicates the operating state when the operating lever 2 is pushed up, and the switch closed position indicated by a dotted line indicates the operating state when the lever 2 is pushed down. The switch closed position indicates the operating state when the operating lever 2 is pressed to the right, and the dotted switch closed position indicates the operating state when the lever 2 is pushed to the left.

By pressing and tilting the operating lever 2 up and down or left and right as described above, the protrusion 1b is moved to the inclined part of the V-shaped groove 3b provided on the cam plate 3,
Therefore, the cam plate 3 is attached to the support shaft portion 2a of the operating lever 2.
move slightly towards. (See Figure 9) However, when the pressing force on the operating lever 2 is released, the cam plate 3 is pressed by the spring 5 and acts to cause the projection 1b to fall into the V-shaped groove 3b, so the pressing force is reduced. When released, the operating lever 2 automatically returns to the state shown in FIG.

On the other hand, when selecting the left side mirror or the right side mirror, the operating lever 2 is rotated in the direction around the axis.
For example, to select the right mirror from the state shown in FIG. 1 where the left mirror is selected, the operating lever 2 is rotated from the L position to the R position in FIG. Note that the chain line in FIG. 1 is an operation knob. In conjunction with this rotation operation, the cam plate 3 rotates, and the protrusion 1b is inserted into the V-shaped groove 3.
b, but the protrusion 1b falls into the V-shaped groove 3b that moves next. Further, the locking rod 2b of the operating lever 2 turns clockwise in FIG. 5 and comes into contact with the other side wall of the bearing portion 4b, and the rotation range of the operating lever 2 is determined by this operation.

Further, the slide block 6 rotates exactly 90 degrees clockwise in FIG. 7 in conjunction with the rotation of the sliding contact portion 2d of the operating lever 2. When the block 6 turns to this position, the sliding terminals 7a and 7b move to the thirteenth position.
× of the printed circuit boards 9 and 10 shown in the figure and FIG.
Change to the position of the mark. In this state, if the operating lever 2 is pushed upward (upward in FIG. 1), the sliding terminals 7a and 7b will be at the positions indicated by the solid circular marks in FIGS. 13 and 14, and the lever 2 will be pushed up. If you press it downward, it will be at the position indicated by the dotted circle mark on the figure. Furthermore, when the operating lever 2 is pushed to the left in FIG. 1, the sliding terminals 7a and 7b are moved to the positions indicated by the solid triangle marks in FIGS. 13 and 14, and the lever 2 is pushed to the right. When operated, the terminals 7a and 7b are displaced to the positions indicated by the dotted triangles in the figure. Therefore, the mirror surface tendency of the left mirror can be adjusted while power is being supplied to the right mirror motor MR and the solenoid SR.

FIG. 15 shows a control circuit for the right mirror formed by the above switch switching, and FIG.
, the switch closed state indicated by a solid line is when the operating lever 2 is pushed upward, and the switch closed state indicated by a dotted line is when the lever 2 is pushed downward.
In FIG. 15b, the switch is closed as shown by the solid line when the operating lever 2 is pressed to the right.
The closed state of the switch indicated by the dotted line is when the lever 2 is pressed to the left.

As described, in the present invention, the power supply side terminal (12th
EO part in Figures and Figure 15) to the printed circuit board 9
, the terminals on the load side (LO in Figures 12 and 15)
Since the switching parts of the terminals (SO parts in FIGS. 12 and 15) are arranged on the printed circuit board 10 and the switching parts of the terminals (SO parts in FIGS. 12 and 15) are constructed by the slide block 6, only one slide block 6 is slid. to select the left and right mirrors,
Also, its mirror tendency can be adjusted. Furthermore, since the fixed terminals are distributed and arranged on the two printed circuit boards 9 and 10 as described above, the terminal configuration does not become cumbersome and it is therefore possible to downsize the printed circuit boards 9 and 10. .

Thus, according to the present invention, it is possible to provide a mirror adjustment switch whose structure is simplified and reduced in size.

Note that, as shown in the above embodiment, the fixed terminal _M2 of the printed circuit board 10 and the corresponding fixed terminal of the printed circuit board 9 are shared when the left mirror is selected and when the right mirror is selected. Therefore, the terminal configuration is further simplified and effective.
