Description

[Detailed Description of the Invention] The present invention mainly relates to a switch mechanism for a remote control mirror for an automobile.

Remote control mirrors for automobiles can tilt the mirror body arbitrarily in four directions (up, down, left and right), and
Since the mirrors are located on the left and right sides of the car, it is necessary to switch between the left and right sides.

For this reason, conventionally, a combination of a two-way switch that switches between the left and right side and a four-way switch that tilts the mirror vertically and horizontally has been put into practical use. It has been proposed that a four-way changeover switch function and a two-way changeover switch function are incorporated into a single switch mechanism, which can be operated by a single operating lever. (See Publication No. 55-26840).

The present invention, similar to the one described in the above-mentioned Japanese Utility Model Publication No. 55-26840, incorporates a four-way changeover switch function and a two-way changeover switch function into a single switch mechanism, and allows this to be operated in a single operation. This relates to a switch mechanism that can be operated by a lever, and in particular, a switch mechanism that can be operated accurately and stably at all times, even though it performs multi-function operations as described above.

bring it into contact with.

The switch mechanism of the present invention in this embodiment is as follows:
It has the above configuration, and its operation will be explained below.

First, four-way switching operations will be explained. That is, when the operating lever 2 is tilted in the direction of the arrow (rightward) in FIG. , the guide member 4 does not slide. Therefore, while this guide member 4 remains in a fixed state, the slide member 5 moves its slide portion 5.
a is guided along the hanging piece 4b of the guide member 4 with which it is engaged and slides in the direction of the arrow. At this time, the slide member 5 is attached to the guide member 4 in the fixed state.
Since it is guided by the hanging piece 4b, accurate and stable sliding can be obtained. Further, even when the operating lever 2 is tilted in the direction opposite to the arrow (to the left), the slide member 5 slides accurately and stably in the direction opposite to the arrow as described above.

Next, when the operating lever 2 is tilted in the front-rear direction on the paper in FIG. 1, the hanging piece 4b of the guide member 4
By engaging with the slide portion 5a of the slide member 5, the slide member 5 integrally engages with the guide member 4 via the guide member 4, and engages the engagement protrusion 4 of the guide member 4.
a is guided along the engagement groove 3b of the base 3 that is engaged with and slides in a direction opposite to the direction in which the operating lever 2 is tilted. At this time, the slide member 5 is guided via the guide member 4 to the engagement groove 3b of the base 3 fixed to the housing 1, so that accurate and stable sliding can be obtained and switching in four directions can be obtained.

Then, move the operating lever 2 forward, backward, left, and right, for example at the 8th
When the operating lever 2 is tilted to the right as shown in the figure, the bush 8 located on the opposite side to the tilting direction of the operating lever 2 is pushed up by the flange portion 2b of the operating lever 2, resisting the spring force of the spring 7, and the housing 1 is retracted. While sinking into the groove 1b, the bush 8 on the opposite side to the sunken bush 8, that is, on the side in the tilting direction of the operating lever 2, protrudes from the storage groove 1b by the spring force of the spring 7 and presses down the flange portion 2b. In this state, release your hand from the operating lever 2 and release the operating lever 2.
When the tilting state of is released, the bush 8, which had been sunk in the storage groove 1b until now, protrudes from the storage groove 1b due to the spring return force of the spring 7 on the opposite side to the tilting direction of the operating lever 2, and pushes down the flange portion 2b. On the other hand, the bush 8 on the side in the tilting direction of the operating lever 2 is slightly sunk into the storage groove 1b while maintaining the balance of the spring force of the spring 7, whereby the operating lever 2 and the slide member 5 automatically return to the neutral position. can do. In this way, since the operating lever 2 is always held at the neutral position by the springs 7 separately arranged in the operating direction via the flange portion 2b, a reliable automatic return can be obtained.
Moreover, since the spring force of the spring 7 acts in the operating direction of the operating lever 2, the operation of the operating lever 2 is further stabilized.

Next, a two-way switching operation will be explained. That is, when the operating lever 2 is rotated about the central axis of the operating lever 2 in the direction of the arrow (rightward when viewed from above) in FIGS. 1, 9, and 10, the operating shaft portion of the operating lever 2 The slide member 5 with which the guide member 2c engages rotates 90 degrees in the direction of the arrow together with the guide member 4 due to the engagement between the slide portion 5a of the slide member 5 and the hanging piece 4b of the guide member 4. Also,
When the operating lever 2 is rotated in the direction opposite to the arrow, the slide member 5 is rotated 90 degrees in the opposite direction to the arrow as described above together with the guide member 4. This results in
Two-way switching is obtained, and in addition to the four-way switching described above, two-way and four-way switching can be performed with a single switch mechanism, and moreover, a single operating lever 2
It can be operated by

Then, move the operating lever 2 in the left and right direction, for example, the 9th
When rotated to the right as shown in the figure, the four bushes 8 installed in the housing grooves 1b in the cross direction of the housing 1 are moved to the flange portion 2b by the rotation of the operating lever 2.
As the bush 8 moves from the concave part 2d to the convex part 2e, it retreats into the storage groove 1b against the spring force of the spring 7, and then when the bush 8 moves from the convex part 2e to the concave part 2d, the spring 7 returns to its original state. The operating lever 2 automatically rotates due to the force, and the four bushes 8 protrude from the storage groove 2b and move into the recess 2d on the right.
located respectively. For this reason, a sense of moderation can be obtained in the two-way switching operation. At this time, due to the engagement between the engagement groove 3b of the base 3 and the engagement protrusion 4a of the guide member 4, the operating lever 2 does not rotate any further.

In the above-described embodiment, the spring 7 for returning to the neutral position is interposed between the housing 1 and the flange portion 2b of the operating lever 2; You can also wear it.

Next, we will discuss the specific configuration and operation of the contact structure, that is, two-way switching in which the operating lever 2 is rotated in either the left or right direction to drive either of the left and right mirrors, and the operating lever 2 is rotated in the front, back, left, or right direction. Four-way switching in which either the left or right mirror is tilted vertically or horizontally will be described.

As shown in FIG. 1, the contact structure 9 is disposed such that a substrate is brought into sliding contact with the bottom surface of the housing 1 by the two contacts 7. The wiring pattern on the board of this contact structure 9 is shown in FIGS.
As shown in the figure, the first

A concave portion is appropriately provided in each conductive portion to prevent shoots due to backlash.

The wiring pattern of the contact structure 9 is as described above, so when the operating lever 2 is located at the left or right neutral position as shown in FIGS. Contact points a, b, c,
d, e, and f are located in the insulating part, and no circuit is formed.

When the operating lever 2 is tilted to the right from this left neutral position, as shown in _FIG . is the seventh conductive part M ₂ and the contact point f is the first conductive part B

A switching device is installed so that when the left solenoid SL is energized, the left mirror tilts vertically, and when the left solenoid SL is not activated, the left mirror tilts horizontally, and M ₂ → M ₁ When the current is in the L direction, the left mirror body is set to tilt to the right by the rotation of the left motor ML, so that the left mirror body can be tilted to the right by tilting the operating lever 2 to the right. be able to.

Conversely, if you tilt the operating lever 2 to the left, the 15th
As shown in the figure, the contact point b is connected to the third conductive part M ₁ L,
Since the contact point c contacts the first conductive part E, the contact point d contacts the second conductive part E, and the contact point f contacts the seventh conductive part _M2 , the left motor ML moves in the _M1L → _M2 direction. A current flows through the motor ML, causing the left motor ML to rotate in the opposite direction, thereby making it possible to tilt the left mirror to the left.

Next, when the operating lever 2 is pushed in the direction of the paper in FIG. ₁ , as shown in FIG. d is the second conductive part E, contact point e is the fifth conductive part
At SL', contact points f contact the seventh conductive portions _M2 , respectively. At this time, since the left solenoid SL is energized, the left mirror body is tilted either up or down, but when the current is in the M ₁ L → M ₂ direction of the left motor ML, the left mirror body is tilted either up or down. By setting the control lever 2 so that it is tilted upward, the left mirror body can be tilted upward by tilting the operating lever 2 to the opposite side.

Conversely, when you pull the operating lever 2 toward you, as shown in _FIG . Department
Since the contact point e contacts the fifth conducting part SL' and the contact point f contacts the first conducting part B, the _left solenoid SL is energized and the left motor ML is energized.
Current flows in the direction of M ₂ → M ₁ L and the left motor
The ML rotates in the opposite direction, thus allowing the left mirror to tilt downward.

Then, rotate the control lever 2 90 degrees to the right,
Switching is made from the left neutral position shown in FIG. 13 through the switching state shown in FIG. 18 to the right neutral position shown in FIG. 19.

When the operating lever 2 is tilted to the right from this right neutral position, the contact point a moves to the seventh point as shown in FIG.
The contact point b is connected to the _first conductive part B, the contact point d is connected to the second conductive part E, and the contact point e is connected to the fourth conductive part M2.
Contact M ₁ R respectively. Therefore, at this time, current flows in the direction of M ₂ →M ₁ R of the right motor MR.
When the right solenoid SR is energized, the right mirror body tilts vertically, and the right solenoid SR
A switching device is installed so that the right mirror body tilts left and right when the motor does not operate, and when the current is in the M ₂ → M ₁ R direction, the right mirror body tilts to the right due to the rotation of the right motor MR. With this setting, the right mirror body can be tilted to the right by tilting the operating lever 2 to the right.

Conversely, if you tilt the operating lever 2 to the left, the 21st
As shown in the figure, contact point a is connected to the second conductive part E, contact point b is connected to the seventh conductive part _M2 , and contact point d is connected to the fourth conductive part M2.
Since the contact point e contacts the first conducting part B at M ₁ R, current flows in the direction M ₁ R → M ₂ of the right motor MR, causing the right motor MR to rotate in the reverse direction. The mirror body can be tilted to the left.

Next, push the operating lever 2 toward the page, and the 22nd
As shown in the figure, contact point a is connected to the second conductive part E, contact point b is connected to the seventh conductive part _M2 , and contact point c is connected to the sixth conductive part M2.
SR', the contact point e contacts the first conductive part B, and the contact point f contacts the fourth conductive part _M1R . At this time,
Since the right solenoid SR is energized,
The right mirror body is tilted either up or down, but when the current of the right motor MR is in the M ₂ → M ₁ R direction, the right mirror body is set to tilt upward. By tilting the lever 2 to the opposite side, the right mirror body can be tilted upward.

Conversely, when you pull the operating lever ₂ toward you, as shown in FIG.
SR', the contact point e contacts the second conducting part E, and the contact point e contacts the fourth conducting part M ₁ R, so the right solenoid SR is energized and the right motor MR M ₁ R is energized. →M Current flows in _two directions, causing the right motor MR to rotate in the opposite direction, thus allowing the right mirror to tilt downward.

As mentioned above, the switch mechanism of the present invention is
Of course, it is possible to incorporate the four-way changeover switch function and the two-way changeover switch function into a single switch mechanism, and operate this with a single operation lever, but in the present invention, the operation Among the lever tilting operations, when the slide member is guided by the guide member, the guide member remains fixed and guides the slide member, and when the lever is tilted in the right angle direction, the guide member and the slide member are integrated. Since it is guided by the engagement groove of the base fixed to the housing, it is possible to perform accurate and stable switching in four directions.Furthermore, when switching in two directions, the engagement between the guide member and the slide member is This has the advantage of being able to integrally combine the two and perform accurate and stable switching.
