Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a two-way switching section that switches which side of each current-carrying body is energized in a circuit equipped with two sets of current-carrying bodies, and a two-way switching section that switches between two sets of current-carrying bodies. The present invention relates to a switch mechanism in which a multi-directional changeover switch section and both switch sections are disposed in a common frame by switching the energization to a current-carrying body in multiple directions.

In this case, since the two-way switching determines which current-carrying body is to be controlled, the operating sensation must be clear, and the operating element must not be able to stop at a position other than the switching position.
Furthermore, it is desirable to have a click feeling (feeling of moderation) when switching, so that it is clear intuitively that the switching to either direction has been achieved.

In addition, in such a switch mechanism, if the two-way switching is performed by, for example, operating a rotor and displacing a slider carrying a contact piece, then the amount of displacement of the operating element and the displacement of the contact piece can be changed. Therefore, if the amount of displacement of the operating element is increased to ensure reliable switching, a considerable amount of space will be required for the displacement of the contact piece. The fact that a considerable amount of space is required for the displacement of the contact piece means that in a switch mechanism in which the multi-directional changeover switch section and the two-way changeover switch section are assembled and housed in a common frame, the space is limited. It is disadvantageous.
In addition, in the case of a structure in which the contact piece is configured to slide on a pattern of a conductive part configured to perform the desired switching, the conductive pattern must necessarily be large enough to correspond to the amount of sliding. Since the conductive pattern is large and the amount of sliding of the contact piece is large, there is a possibility of trouble due to wear.

In view of the above circumstances, the present invention provides two functions of the switch mechanism.
When switching directions, the rotating element that performs the switching operation is energized in one of two directions, ensuring reliable switching without stopping in the middle, and giving the switch the click feeling (moderation feeling) that it should have. Moreover, by minimizing the amount of displacement of the contact piece, it is an object of the present invention to provide a switch mechanism that can miniaturize the entire mechanism and simplify the pattern, and prevent troubles caused by wear.

Hereinafter, an example of implementation of the present invention will be described with reference to the drawings.

In this example, the present invention is applied to a remote control mirror for an automobile. That is, a two-way switch section is used to select which of the left and right mirrors to drive, and then a multi-directional switch section is used to select whether to tilt the mirror up, down, left, or right. It is something. (The specific circuit configuration of this example will be shown later).

As shown in FIGS. 1 to 4, the switch mechanism of the present invention incorporates a multi-directional changeover switch section configured to achieve desired switching and a two-way changeover auxiliary switch section within a common frame 1. Arrange. This switch mechanism is provided with an operator 2 for performing multi-directional switching and a rotating element 3 for two-directional switching. The rotating element 3 is arranged around the operator 2 as shown in FIGS. 2 and 3. In the illustrated example, teeth are formed on the outside so that the rotating element 3 can be easily operated (see FIG. 1).

A protrusion 31 is provided on the rotating element 3 in a protruding manner. this is,
The contact piece 4 is moved as the element 3 rotates, thereby switching between two directions. In the illustrated example, the projection 31 is formed by hanging downward from one end of the rotating element 3 as shown in FIG.
It is designed to be inserted and moved.

Further, a long groove 5 is formed in the rotating element 3 (fifth groove).
(see Figure and Figure 6). As shown in the figure, this long groove 5 is in the shape of a dogleg whose center is slightly closer to the center of rotation.The rising part 61 of the sliding part 6 is inserted into the long groove 5, and one end of the coil spring 7 is inserted into the frame. The fixing piece 8 fixed inside the body 1 is fixed by being hooked onto one end 83, and the other end is hooked onto the rising portion 61 of the sliding portion 6, thereby constantly pulling the sliding portion 6 in the direction of arrow A. ,
As a result, the rising portion 61 of the sliding portion 6 is biased to be attracted to either end of the long groove 5.

In this way, the sliding part 6 is engaged in the long groove 5,
When rotating the rotating element 3 for two-way switching,
When the sliding part 6 slides along the long groove 5 and switches the rotating element 3 from one switching position to the other switching position, it does not stop midway, and moreover, due to the tensile force of the coil spring 7, a certain click feeling ( Switching is done with a sense of moderation.

That is, if the long groove 5 is formed into a dogleg-shaped groove with the center near the rotation center, when the rotating element 3 is rotated in the direction of arrow B from the position shown in FIG.
The long groove 5 also moves as shown in FIG. 6, but in the state shown in FIG. 6, the distance between the sliding part 6 and the center of rotation becomes shorter, so the coil spring 7 causes Since it is pulled toward the center of rotation as indicated by arrow C and a biasing force is acting in the direction of arrow A, when the rotating element 3 is slightly displaced in the direction B compared to the state shown in FIG. 6, the coil spring 7 The rotating element 3 automatically rotates due to the urging force of
It collides with the other switching position and stops. The reason why the center portion of the long groove 5 is slightly closer to the center of rotation to form a substantially doglegged shape is to ensure such reliable switching and to provide a click feeling.

As a result, the sliding part 6 transmits the biasing force of the coil spring 7 to the rotating element 3 while performing an expanding and contracting motion along the arrows A and C, so that the rotating element 3 reaches the terminal position without stopping at an intermediate position. It is possible to perform two-way switching by rotating reliably until the end of the switch, and also to switch with a click feeling (feeling of moderation).

With such rotation of the rotating element 3, the protrusion 31 moves the contact piece 4, thereby achieving switching on the conductive part 11, which is based on the following configuration.

That is, the rotating element 3 of the present invention displaces the slider 9 carrying the contact piece 4 as shown in FIG. 3, and achieves switching by the displacement of the contact piece 4. The drive is
This is done by the protrusion 31 provided on the rotating element 3 pushing against the walls 91 and 92 of the slider 9.

As described above, the slider 9 has each wall portion 91, 92.
is adapted to move by being pushed by the protrusion 31 as the rotating element 3 rotates, but both wall portions 9
A space 93 is formed between the projections 1 and 92 along the direction of displacement of the projection 31 so that the projection 31 can be displaced within the space. That is, as shown in FIGS. 8 to 10, the slider 9 has two columnar protrusions protruding from both ends of the upper surface of an arc-shaped base portion 94 to form wall portions 91 and 92.
, and an arc-shaped space 93 is formed between them. The protrusion 31 comes into contact with the walls 91 and 92, and the slider 9
, and one wall 91 is moved by the protrusion 3.
When 1 pushes, the slider 9 moves as shown by the arrow D in the figure, and conversely, when the protrusion 31 comes into contact with the other wall 92 and pushes it, the slider 9 moves in the opposite direction as shown by the arrow E.
Move with. Therefore, when trying to displace the slider 9 from one switching position, for example, a position where the protrusion 31 is in contact with the wall 91, to the other switching position, the rotating element 3 is rotated to move the protrusion 31 in the direction of the arrow E. However, during this movement, first the protrusion 31
moves in the space 93 and plays during this time, and after this amount of play, the protrusion 31 comes into contact with the other wall 92, and thereafter pushes the wall 92 to displace the slider 9. Therefore, when switching between two directions, the rotating element 3 is moved against the coil spring 7.
, and at that time, the distance that the slider 9 moves is longer than the distance that the rotating element 3 moves.
1 is playing, that is, the length of the space 93 is shortened. The same holds true when the slider 9 is displaced from the switching position where the protrusion 31 is in contact with the wall 92 to the other switching position.

In this example, the rotation of the rotating element 3 for switching is
It is set at 90° displacement. This is because reliable switching can be expected with this amount of displacement. on the other hand,
The space 93 of the slider 9 has a length corresponding to about 45 degrees from the center of rotation. Therefore, rotating element 3
When the slider 9 rotates 90 degrees, the amount of displacement of the slider 9 decreases by the amount of play, so the slider 9 rotates approximately 45 degrees. Therefore, the amount of displacement can be reduced to half of the slider 9.
The space for displacement can be reduced. To explain with reference to FIGS. 5 and 6, when the rotating element 3 is rotated in the direction of arrow B from the state shown in FIG.
The slider 9 begins to move from the point in FIG. 6 when it has rotated 45 degrees. This mechanism is the 11th
Also shown in the figure.

As mentioned above, the contact pieces 4 are attached to both ends of the bottom of the slider 9, and since the contact pieces 4 are supported by the slider 9 and move, the amount of displacement thereof can be smaller than the amount of displacement of the rotating element 3. . Therefore, the pattern of the conductive portion on which the contact piece 4 should slide can be made smaller, the pattern can be simplified, and the wear caused by sliding can be reduced. In addition,
9 and 10 show a state in which the contact piece 4 is disposed only on one side, and the other side is shown only by imaginary lines. This is to clearly indicate the bottom of the slider 9 where the contact piece 4 is to be attached.

In the illustrated example, the mirrors are tilted both to the right and to the left using a wiring structure as shown in FIG. A pattern of conductive parts is provided on the base 11, and by sliding the contact piece 4 through 45 degrees, it is possible to switch whether the right or left mirror is energized. In the figure, reference numeral 4' denotes a contact element, which slides vertically and horizontally on each conductive portion, thereby making it possible to tilt the mirror vertically and horizontally. The illustration shows the state at the neutral position, and in this state, no current is applied for tilting. M
_R and M _L are motors, S _R and S _L are solenoids,
The magnetic attraction means is used to switch whether the mirror tilts in the vertical direction or in the horizontal direction.

FIG. 13 shows a circuit diagram in this neutral state. In this case, the contact piece 4 is the motor M _R for the right side mirror.
As described above, this position can be switched by rotating the rotary element 3 through 90 degrees and displacing the contact piece 4 through 45 degrees. FIG. 14 shows a case where the multi-directional switching operator 2 is tilted upward in this state. As shown,
Electricity is applied to the motor M _R and solenoid S _R , and the mechanism is set so that when the solenoid S _R is energized, the motor M _R tilts the mirror in the vertical direction, and the current in this direction causes the mirror to tilt upward. By doing so, the operator 2 is tilted upward to tilt the mirror upward. (Note that the contact 4' is sliding upward in the opposite direction to the operating element 2).

FIG. 15 shows a case where the operator 2 is tilted downward. In this case, since the motor M _R and solenoid S _R are energized, the mirror will tilt either up or down, but since the direction of the current in the motor M _R is opposite to that shown in Fig. 14, the mirror will tilt downward. It will be tilted.

FIG. 16 shows a case where the operator 2 is tilted to the left.
At this time, the solenoid S _R is not energized, and in such a case, the motor M _R is configured to tilt the mirror to either the left or right, and the mirror is tilted to the left in the direction of this current. As a result, the operating feel of the operator 2 matches the tilting direction of the mirror, and erroneous operations are prevented.

FIG. 17 shows a case where the operator 6 is tilted to the right. The direction of energization is reversed to that shown in FIG. 16, and the mirror is tilted to the right by motor M _R.

In this way, in this embodiment, the operating feeling and the actual operation are made to match, so that the operability is extremely good.

The multi-directional switching in the illustrated example is performed by restricting the tilting of the operator 2, which passes through the upper part of the frame 1 and is surrounded by the rotating element 3, in four directions, as shown in FIGS. 2 to 4. ing. In this case, a spring 23 is interposed between a hemispherical pivot portion 21 that moves integrally with the operator 2 and a lower hemispherical member 22 that opposes it, thereby enabling automatic return to the neutral position. . Four-way sliding is achieved by the guide member 24 and movable piece 25.
This is done by a contactor 4' disposed at the bottom of the movable piece 25 (see FIG. 3). The tilting movement in four directions at this time is allowed by arranging the shaft 21' of the pivot portion 21 in a pair of protrusions 82 protruding from the fixed piece 8 shown in FIG.

As described above, the present invention includes a multi-directional changeover switch section configured to achieve desired switching;
In a switch mechanism in which a two-way changeover auxiliary switch part and a two-way changeover auxiliary switch part are arranged in a common frame, the two-way changeover auxiliary switch part is configured to be operated by a rotating element arranged around an operator for multi-directional switching operation. ,
The rotating element is provided with a long groove shaped like a dogleg whose center is near the center of rotation, and a sliding portion biased by a spring in a direction away from the center of rotation is engaged in the long groove. The rotating element is configured to rotate the rotating element to a position where the sliding part collides with one end of the long groove of the rotating element by a biasing force, and the rotating element carries a contact piece. A projection for displacing the slider is formed, and the slider is provided with a pair of wall portions located apart from each other with a space along the displacement direction of the projection, and the slider is configured to be driven by the projection. Since the amount of sliding has been made small, if the rotating element is operated by at least 1/2 of its operating amount, the rotating element will not stop in the middle of the specified two-way switching and will automatically reach the final two-way switching position. It is possible to rotate the rotating element in a controlled manner and switch between two directions with a click feeling (feel of moderation) that is desirable for a switch.Moreover, when doing so, the amount of displacement of the contact piece is kept small and the entire mechanism is miniaturized. This has the effect of reducing the size of the wiring pattern and preventing troubles caused by wear.
