Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a switch mechanism. In particular, the present invention relates to a switch mechanism suitable for tilting a remote control mirror for an automobile in a desired direction vertically or horizontally.

A four-way switch is used to tilt an automotive remote control mirror in any desired direction, up, down, left, or right. However, since the mirrors are located on the left and right sides, it is necessary to use two four-way changeover switches to control both. Alternatively, if an attempt is made to control both with a single four-way changeover switch, it is necessary to provide a separate changeover switch, which complicates the overall configuration and increases costs.

In addition, there are two-motor type control mirrors for automobiles that use separate motors to tilt vertically and horizontally, and one-motor type that uses one motor in combination with a solenoid to change the tilting direction. In either case, it is desired to eliminate erroneous operations by matching the operating direction of the switch with the tilting direction of the mirror.

In response to the above-mentioned demands, the present invention provides a switch mechanism in which a four-way switch section and a two-way switch auxiliary switch section are incorporated into a single frame, which is suitable as a switch mechanism for a one-motor type remote control mirror. This is what I am trying to do.

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in Fig. 11, remote control mirrors for automobiles include a motor M _L for the left side mirror.
and a motor M _R for the right side mirror, and drive units L and R each having solenoids S _L and S _R for switching the direction of tilting of each mirror.

As shown in FIG.
are arranged in a common frame 3, and the four-way changeover switch section 1 has first to third switches that are operated by the operator 11 and slide on the contact structure 9.
Each contact 8 has a first to a third contact at a position corresponding to the apex of an equilateral triangle.
The two-way changeover auxiliary switch section 2 is configured to be operated by an operating piece 30.

As shown in FIGS. 1 to 3, the four-way switch section 1 includes an operator 11 inserted into the frame 3 from an upper opening 3a of the frame 3, and an operator 11 disposed inside the frame 3. An automatic return mechanism 12 for returning the lever operator 11 to the neutral position is provided. A fixing member 4 is fixed inside the frame 3 with its side surface in close contact with the inner surface of the frame 3. As shown in FIG. , which is also common to the two-way switching auxiliary switch section 2. Furthermore, three contactors 8, first to third, are arranged at the bottom of the four-way switch section 1, and these are formed on the upper surface of the insulating substrate 7, which corresponds to the bottom surface of the frame 3. The contact structure 9 is operated by the operator 11 to slide. The contact 8 is attached to the bottom surface of the movable piece 5.
The necessary sliding movement is achieved by moving the movable piece 5 in four directions with the operator 11 via the guide member 6.

The contactor 8 has a triangular shape as shown in FIG. 10, and has three contact points a, b, and c on its bottom surface.
is installed protrudingly. These contact points a, b, and c are formed at positions corresponding to the vertices of an approximately equilateral triangle. . In the figure, reference numeral 84 denotes an upright piece, which is attached to the bottom surface of the movable piece 5 via a coil spring while being in close contact with the side surface of the movable piece 5. Movable piece 5
Three such contacts 8 are attached to the.

The automatic return mechanism 12 includes a hemispherical upper sliding member 10 fixed approximately at the center of the operator 11, and a hemispherical lower sliding member 10' provided below the operator 11 so as to be slidable in its axial direction. , both members 10,1
The spring 13 presses the spherical parts of the upper sliding member 10 and the lower sliding member 10' against the frame 3 and the fixed member 4, and tilts the armature 11. When the knob 16 of the operating element is released after this, the operating element 11 is configured to return to its original neutral position by the biasing force of the spring 13. That is, the upper inner surface of the frame 3 has a tape-shaped recess, and four protrusions 3c are formed at equal quarter positions as shown in FIG. The spherical portion of the member 10 is brought into pressure contact. The upper surface of the fixing member 4 also has a tapered recess, into which the spherical portion of the lower sliding member 10' is pressed. A groove 4a is also formed in this tapered recess for the same reason (Fig. 8a, b).
reference).

In addition, in this switch mechanism, two cylindrical shafts 21a, 21a are provided at the lower part of the upper sliding member 10 of the automatic return mechanism 12, as shown in FIG. A groove 3b is formed in the frame 3 to serve as a bearing. As shown in FIG. 5, this groove 3b has a width d that is large enough to receive the shaft 21a, so that the shaft 21a can rotate about the axis as indicated by arrow A in the groove. This rotation is performed when the operator 11 is tilted in the left-right direction in FIG. 1 and along a line perpendicular to the paper surface in FIG. 2 (for example, in a direction from the paper surface to the spine of the paper).

On the other hand, the height of this groove 3b is as shown in FIG.
Raise it as high as shown in l′ and leave some space in the vertical direction. Therefore, when the operator 11 is tilted in a plane perpendicular to the above, that is, in the left-right direction (direction of arrow C) of the plane of FIG. 2, the operator 11 and the automatic return mechanism 12 attached thereto is tilted about point Q, and at the same time the shaft 21a is tilted within the groove 3b as shown by arrow B (see FIG. 3). Note that the groove 3b also has a margin l'' (see FIG. 5) between its end and the end of the shaft 21a.

Further, in this embodiment, the guide member 6 has a rectangular plate shape as shown in FIG. A depending piece 62 is formed, 61, 62 being approximately perpendicular to each other. Note that the center portion is a hole 63 through which the operator 11 passes.

The rising piece 61 of this guide member 6 is connected to a groove 41 provided oppositely on two sides of the lower surface of the fixed member 4.
(see FIG. 8), and is guided to slide in the left-right direction in FIG. 1 (direction perpendicular to the plane of the paper in FIG. 2). When moving in this manner, the movable piece 5 and the hanging piece 62 are slid in the same direction. In addition, in the case of sliding in a direction perpendicular to this, that is, in the left-right direction in FIG. The movable piece 5 slides along the hanging piece 62 of the guide member 6. The surface of the movable piece 5 along the hanging piece 61 is indicated by the reference numeral 51 in FIG. Therefore, the guide member 6
The movable element 5 is guided by the four directions. Note that FIG. 3 shows the case where the θ° operation element 11 is tilted from the state shown in FIG.

In addition, in this embodiment, as shown in FIG.
A fitting protrusion 21b that can be fitted in is provided in an annular shape on the side of the insertion hole 21c of the operator 11, a notch 21d is formed in the fitting protrusion 21b, and the fitting protrusion 21b is fitted into the groove 1c of the operator 11. match. This is operator 11
This is to prevent it from coming off.

Next, the auxiliary switch section 2 will be explained. As described above, this auxiliary switch section 2 is housed within the same frame body 3 as the four-way changeover switch section 1, and is therefore adjacent to the four-way changeover switch section 1.

The auxiliary switch section 2 of this embodiment has an operation lever 3.
0, and an auxiliary movable element 33 that is driven by this and slides on the contact structure 9' on the inner surface of the base 7.

The upper end of the lever 30 is exposed to the outside through the opening 3d of the frame 3 and can be operated, and the lower end passes through a hole in the fixing piece 4. This lever 30
A shaft 30a protrudes from a portion located inside the frame 3, and this shaft 30a is supported by a bearing 4b defined between the frame 3 and a recess formed on the upper surface of the fixing member 4. It is pivoted and configured to be able to tilt at an angle α° in the left-right direction in Figure 4 around this point (see also Figure 8). A cut groove 30b is formed at the lower end of the lever 30, into which a protrusion 31a protruding from the upper part of the auxiliary movable piece 31 is engaged, and the protrusion 31a is clamped to the lower end of the lever 30. As a result, the movable piece 31 is slid as the lever 30 is tilted, as shown by the imaginary line in FIG. A recess is provided approximately in the center of the lower surface of the movable piece 31, and a spring 32 is disposed in the recess, and a contact 33 is brought into contact with the recess. The contactor 33 is integrally formed of a metal piece with good conductivity.

The contact piece 33 slides on the contact structure 9' to perform two-way switching, and the three contacts 8 mentioned above slide on the contact structure 9 to perform four-way switching.

The contact structure 9 and the contact 9' are as shown in FIG. This will be explained below, as well as the operation in which the three contacts 8 and the contact piece 33 slide on the contact structure 9 and the contact structure 9' to perform switching.

The contact structure 9 consists of first to sixth conductive parts 91 to 96. The contact structure 9' consists of a central conductive part 9a and left and right conductive parts 9b, 9c.

The first conductive part 91 is located at the center of the upper part of the substrate 7, and has a right protrusion 911 and a left protrusion 912 that protrude to the right and left, respectively, at the upper right and lower left.
The second conductive part 92 is located at the lower left of the first conductive part 91, has a notch 92' in the center, and has a rightward protrusion 921 in the upper right. The third conductive part 93 is located at the lower right of the first conductive part 91 and is lined up on the right side of the second conductive part 92. This third conductive portion 93 also has a notch 93' in the center and a leftward protrusion 931 in the lower left. The fourth conductive part 94 is
It has a horizontal U-shaped notch 94' that is located below the second conductive part 92 and opens to the right. The fifth conductive part 95 is located below the third conductive part 93 and has a horizontal U-shaped notch 95' that is open to the left. The sixth conductive part 96 hangs down along the left side of the substrate 7, passes through the left sides of the second and fourth conductive parts 92 and 94, bends to the center of the lower side of the substrate 7, and forms the contact structure 9'. The third and fifth conductive parts 93 and 95 are integrated with the central conductive part 9a, and then extend to the upper right from the central conductive part 9a and rise along the right side of the substrate 7.
It passes on the right side of And this sixth conductive part 9
A rightward protrusion 961 is formed at the upper left end of 6, and a leftward protrusion 96 is formed slightly below the right upper end.
2 is formed.

The contact structure 9' includes a left conductive part 9b and a central conductive part 9.
a, the right conductive parts 9c are lined up horizontally in a row from left to right.

Motor M _R and solenoid S _R for the right side mirror
The connection terminal of the left side mirror motor M _L and the solenoid _SR are also connected to the first conductive part 9 . The other terminal of the solenoid S _R on the right side is connected to the fourth conductive part 94, and the other terminal of the motor M _R is connected to the left conductive part 9b of the contact structure 9'. The other terminal of the solenoid S _L on the left side is connected to the fifth conductive part 95, and the motor M _L
The other terminal is connected to the right conductive portion 9c of the contact structure 9'. The power supply V has its positive end connected to the second conductive part 92 via the fuse f, and its negative end connected to the third conductive part 93.

The three contacts 8 are located on the contact structure 9 configured as described above, and in the neutral state they are arranged as shown in FIG. 11.

That is, the first contact point 81a of the first contact 81 is located above the left protrusion 912 of the first conductive part 91, and the second contact point 81b is located above the left protrusion 961 of the sixth conductive part. The third contact point 81c is located below the notch 92' of the second conductive part 92.
It is located above. The second contact 82
The contact point 82a is on the upper right protrusion 9 of the sixth conductive part 96
62 and a second contact point 82
b is located below the right protrusion 911 of the first conductive part 91, and the third contact point 82c is located below the third conductive part 93.
It is located on the notch 93' of. Third contact 8
3, the first contact point 83a is located between the protrusion 921 of the second conductive part 92 and the protrusion 931 of the third conductive part 93, and the second contact point 83b is located between the protrusion 921 of the second conductive part 92 and the protrusion 931 of the third conductive part 93.
4, and the third contact point 83c
is located in the notch 95' of the fifth conductive part 95.

Therefore, the contact points of all the contacts 81 to 83 are on the insulating part and are not in contact with any conductive part.

On the other hand, the auxiliary contact piece 33 is simply in contact with either the left or right side, but in the illustrated state, the central conductive portion 9a and the left conductive portion 9b are in contact. In this case, since the lever is tilted to the right, the mirror on the right side is tilted to match the operational feel and the direction of operation.

When the operator 11 is in the neutral position, the contacts 91 to 83 are not in contact with any of the conductive parts 91 to 96 as described above, so the circuit is open and no current is applied to any of them. A circuit diagram at this time is shown in FIG.

Next, when the contacts 81 to 83 are slid upward on the contact structure 9, it becomes as shown in FIG. 13. At this time,
Since the operator 11 is tilted downward, the mirror can be set to tilt downward, thereby making it possible to match the operating feeling with the operating direction. That is, at this time, the third contact point 81c of the first contactor 81 comes off from the notch 92' of the second conductive part 92 and comes into contact with the conductive part 92,
1b contacts the protrusion 961 of the sixth conductive part 96, so that the side of the power source V is connected from the second conductive part 92 to the first
It is connected to the sixth conductive part 96 via the contact 81, which is integrated with the central conductive part 9a, and further connected to the contact piece 3.
3 to the left conductive portion 9b, and thus serves as one terminal of the motor M _R for the right side mirror. At the same time, the first contact point 83a of the third contact 83 is connected to the second contact point 83a.
The second and third contact points 83b and 83c are in contact with the protrusion 921 of the conductive part 92, respectively.
The conductive portions 94 and 95 come off from the notches 94' and 95' and come into contact with the conductive portions 94 and 95, respectively. Therefore, the right side solenoid S is connected via this third contact 83.
It also serves as one terminal of _R. On the other hand, the second contact 82
The second contact point 82b contacts the right protrusion 911 of the first conductive part 91, and the third contact point 82c contacts the notch 91.
3' and comes into contact with the third conductive part 93. Therefore, the side of the power supply V is connected from the third conductive part 93 to the first conductive part 91 via the second contact 82, and is connected to the right side mirror motor M _R and the solenoid S _R. The terminal becomes

With this circuit configuration, the mirror motor M _R and the solenoid S _R operate. Therefore, when the solenoid S _R operates, a mechanism is set up to tilt the mirror upward or downward, and the motor M _R
By setting it so that it tilts downward when obtaining a current in this direction, when the operator 11 is tilted downward, the mirror can be tilted downward, and the circuit state at this time can be checked. It is shown in FIG.

At this time, the solenoid S _L for the left side mirror
The left side mirror does not move because the motor M _L is not energized, although it is energized and starts to operate.

Next, a case will be described in which the operator 11 is tilted upward and the contacts 81 to 83 are slid downward.
At this time, the positions of the contacts 81 to 83 are as shown in FIG. 15. In this case, the third contact of the first contact 81
The contact point 81c and the first contact point 81a are the second conductive part 9
2 and the left protrusion 912 of the first conductive part 91 to connect both the conductive parts 91 and 92, so that a common terminal is formed between the solenoid S _R and the motor M _R on the right side. On the other hand, the third contact point 82c and the first contact point 82a of the second contactor 82 are in contact with the third conductive part 93 and the protrusion part 962 of the sixth conductive part 96, so that both the conductive parts 93,
96 is connected, and thus one terminal of the motor M _R becomes. At the same time, the third contactor 83 connects the third conductive portion 9 with the first contact point 83a and the second contact point 83b.
3 and the fourth conductive portion 94, it also serves as one terminal of the solenoid S _R. Therefore, the solenoid S _R and the motor M _R are energized, but the direction of the current is opposite to that in FIG. 13.

Since the operation of the solenoid S _R does not change depending on the direction of the current, the motor M _R remains set to tilt the mirror upward or downward. Moreover, since the motor M _R rotates in the opposite direction to that in the previous case, the mirror will now tilt upward.

Therefore, the mirror can be tilted upward by tilting the operator 11 upward.

In this case as well, the left side solenoid S _R is energized, but the left side mirror does not tilt.

Next, referring to FIG. 17, a case will be described in which the operator 11 is tilted to the right and the contacts 81 and 83 are slid to the left on the contact structure 9.

At this time, the side of the power supply V is connected from the second conductive part 92 to the sixth conductive part 96 via the first contact 81, and therefore, one terminal of the motor M _R is connected via the contact piece 33. . On the other hand, the power supply V side is the third
The conductive part 93 is connected to the first conductive part 91 via the second contact 82, and thus becomes a common terminal with the solenoid S _R of the motor M _R . Therefore, at this time, the motor M _R is energized, but the solenoid S _R
is not energized. By setting the motor M _R to tilt the mirror to the right or left when the solenoid S _R does not operate, and tilting the mirror to the right when the current is in the same direction, the operator can be You can tilt the mirror to the right by tilting it to the right.

Conversely, if you tilt the operator 11 to the left, the contact 81
~83 slides to the right on the contact structure 9, and at this time the mirror tilts to the left.

That is, as shown in FIG. 19, since the side of the power source V is connected from the second conductive part 92 to the first conductive part 91 via the first contact 81, the solenoid S _R of the motor M _R is now connected. The terminal becomes . Also, the side of the power supply V is the third conductive part 93 → the second contact 82 →
Sixth conductive part 96 → central conductive part 9a → auxiliary contact piece 3
3 → Connected to the left conductive part 9b, and becomes the other terminal of the motor M _R. Therefore, the motor M _R has the 17th
The current flows in the opposite direction to that shown in the figure, and the mirror tilts to the left in the opposite direction.

The above description has been made of the case where the auxiliary contact piece 33 connects the center conductive part 9a and the left conductive part 9b by the operation piece 30, thereby tilting the mirror on the right side. Fold down the center conductive part 9a
The same applies to the case where the mirror on the left side is tilted by connecting the right conductive portion 9c to the right conductive portion 9c.

FIG. 21 shows a part of the contact structure 9 on the base and the shape of the contact structure 9' changed. That is, two central conductive parts 9a simply protrude downward from the lower side of the sixth conductive part 96.
With this configuration, unlike the cases shown in FIGS. 11 to 20, the contact piece 33 rarely slides on the central conductive portion, so that wear of this portion can be reduced. FIG. 21 shows the case where the contacts 91 to 83 are in the neutral position, and the circuit diagram at this time is shown in FIG. 22. Since the operation is the same as that described using FIGS. 11 to 20, detailed illustrations and explanations will be omitted.

As detailed above, the switch mechanism of the present invention includes:
A four-way changeover switch part and a two-way changeover auxiliary switch part are arranged in a common frame, and
The four-way switch section is equipped with three contacts that slide on a contact structure that is operated by an operator.

Since the mirrors are connected as shown in FIG. 1, the operating feeling and operating direction of the one-motor type remote control mirror can be matched, and the mirror can be operated simply and easily without fear of erroneous operation.
