Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention applies to any drive motor for tilting the mirror surface of an electric remote control mirror for automobiles around a horizontal axis or around a vertical axis. It is related to the control switch for forward or reverse rotation.

[Conventional technology]

In an electric remote control mirror device for an automobile, a motor for tilting a mirror surface in vertical and horizontal directions is disposed within a mirror housing. The vertical tilting of the mirror surface is achieved by rotating one corresponding motor in the normal or reverse direction, and the horizontal tilting is achieved by rotating the other corresponding motor in the normal or reverse direction. Control of forward or reverse rotation of the motors is performed by a control switch including a control circuit disposed between each motor and a power source.

The control switch is comprised of an operation switch for tilting the mirror up and down and left and right, and a changeover switch for tilting either the left or right mirror of the vehicle.

Such a control switch was created by the inventor of the present application and is disclosed in Japanese Patent Application No. 59-271941 filed on December 26, 1980 by the applicant of the present application.

A control circuit using such a control switch is shown in FIG. The control switch 10 is a first fixed contact that is connected to one terminal of a motor A, B for tilting the left and right mirrors A and B of the automobile around a horizontal axis via a slide contact 70 of the changeover switch. 20 and a pair of fixed contacts 21 and 22 respectively connected to the negative and positive poles of the power source 23, and a motor A2 for tilting the mirrors A and B around the vertical axis. ．． The second fixed contact 40 is connected to one terminal of B2 via the slide contact 72 of the changeover switch, and the fixed contact pair 4L 42 is connected to the negative and positive poles of the electric aI 23, respectively. Fixed contact group, motor Al, B1. At, B
A third fixed contact 5 commonly connected to the other terminals of 2
0 and a third fixed contact group consisting of a pair of fixed contacts 51 and 52 connected to the negative pole and the positive pole of the power source 23, respectively. These fixed contact groups are formed on the printed circuit board 14, and each fixed contact 20, 40, 50 is connected to one of the fixed contact pairs by a bridge member 25, 45, 55 provided corresponding to each fixed contact group. It is now possible to do so. Usually each fixed contact 20.4
0.50 is connected to the fixed contact connected to the negative pole of the power supply 23, but the bridge member deforms elastically only when the peripheral surface of the corresponding bridging member on the opposite side of the fixed contact receives external force. Each fixed contact is connected to the one connected to the positive pole of the power source 23. These bridge members are configured to be pressed by a rectangular push plate that has vertical and horizontal tilting direction indicating portions on its surface, and has tapered surfaces on its back surface that contact the circumferential surfaces near both ends of each bridge member. The legs are integrally formed. Each bridge member is elastically deformed by the tapered surfaces of the two legs pressing the peripheral surface of the bridge member downward.

If you want to tilt the left mirror A of the two left and right mirrors using such a control switch, use the slide contact 70.72 that constitutes the changeover switch.
Slide it to the right.

The mirror A can be tilted in a desired direction by pushing any one of the U, D, L, and R display portions of the push plate. FIG. 14 shows the polarity of the fixed contacts 20, 40, 50 during switching.

For example, when the U display section is pushed, only the first bridge member 25 is elastically deformed, and only the fixed contact 20 is connected to the positive pole of the power supply 23, and the other fixed contacts 40 and 50 are connected to the negative pole. It is in the same state as it is. Therefore motor A1
A current flows from the fixed contact 20 to the fixed contact 50, causing the motor A to rotate normally and the mirror A to tilt upward around the horizontal axis.

Further, when the D display section is pushed, the second bridge member 45 and the third bridge member 55 are elastically deformed, and both the fixed contact 40 and the fixed contact 50 are connected to the positive pole of the power source 23. Then, a current flows through the motor A1 from the fixed contact 50 to the fixed contact 20, causing the motor A1 to rotate in reverse, and the mirror A to tilt downward around the horizontal axis. However, the fixed contact 20 remains connected to the negative terminal of the power source 23, and both the fixed contact 40 and the fixed contact 50 connect to the positive terminal of the power source 23 at the same time or at an earlier timing than the fixed contact 40. If the fixed contact 40 is connected to the positive pole earlier than the fixed contact 50, the motor A2 will be reversed before the motor A1 is driven. A potential difference may occur between the input and output terminals, which may cause malfunction. This also applies to the case where the R display section is pushed, which poses a problem that is not favorable for safe driving.

An object of the present invention is to provide a control switch that is free from malfunction during switching.

[Means for solving problems]

To achieve the above object, the present invention provides a first fixed contact to be connected to one terminal of a motor for tilting a mirror around a horizontal axis, and one terminal of a motor for tilting a mirror around a vertical axis. A second fixed contact to be connected to the terminal of the motor, a third fixed contact to be commonly connected to the remaining terminals of the motor, and each of these fixed contacts is normally connected to the negative pole of the power supply, and the operation is started. In the state, the first to third bridge members made of a conductive elastic body are slidably arranged so as to be connected to the positive electrode, and the upper and lower bridge members are arranged in relation to the bridge members. It has left and right tilting direction indicating parts and a push plate for operating those bridge members, and when the first to third bridge members respectively move from the normal state to the operating state, the third bridge The sliding amount of the member is set to the first and second
It is characterized in that it is set to be smaller than the sliding amount of the bridge member.

[Effect]

When the U display part or the L display part of the push plate is pushed, respectively, the first bridge member or the second actuating member is actuated independently, and the first fixed contact or the second fixed contact is connected to the positive terminal of the power supply, respectively. Because of the connection, the motor for tilting the mirror around the horizontal axis or the motor for tilting the mirror around the vertical axis is rotated in the normal direction. When the D display portion of the push plate is pushed, both the second bridge member and the third bridge member are operated, but the sliding amount of the third bridge member is smaller than the sliding amount of the second bridge member. Because of this setting, the third bridge member is connected to the positive pole of the power supply at an earlier timing than the second bridge member, and no malfunction occurs.

At this time, the motor that tilts the mirror around the horizontal axis is reversed.

If you further push the R display part of the push plate,
Both the first bridge member and the third bridge member are actuated, but since the sliding amount of the third bridge member is set to be smaller than the sliding amount of the first bridge member, the third bridge member is activated. It is connected to the positive pole of the power supply at an earlier timing than the first bridge member, and malfunctions do not occur.

At this time, the motor that tilts the mirror about the vertical axis is reversed.

The printed circuit board 14 is formed into a substantially rectangular shape, and its upper side corresponds to the U display part of the push plate 16, and its lower side and
The left and right sides correspond to the L and R display sections, respectively. A fixed contact 20 and a corresponding pair of fixed contacts 21 and 22 are arranged along the upper side so as to cover approximately 172 mm of the upper side. A bridge member 25 is arranged to connect the fixed contact 20 to either of the fixed contact pair 21.22, and normally the fixed contact 20 and the fixed contact 21.

A fixed contact 30 is arranged adjacent to the fixed contact 20, and a fixed contact 31 is further arranged, and a bridge member 35 bridges both the defining contacts 30 and 31. Printed circuit board 14
Similarly, a fixed contact 40 and a pair of fixed contacts 41 and 42 corresponding to the fixed contact 40 are disposed along the lower side, and a bridge member 45 is further disposed, and a bridge member 45 is further disposed. A fixed contact 40 and a fixed contact 41 are connected. A fixed contact 50 is arranged adjacent to the fixed contact 40. Corresponding to the fixed contact 50, a fixed contact pair 51.

52, the bridge members 25, 45, 55 constitute a switching mechanism for moving the mirror in the vertical and horizontal directions.

If the distance between the fixed contact pair 21.22 is a, the distance between the fixed contact pair 41.42 is b, and the distance between the fixed contact pair 51.52 is C, then these distances are C<a and c<b. is set to be.

Further, a fixed contact 60, a fixed contact 63, and a fixed contact 65 are arranged at positions sandwiching an opening 57 provided in the center of the printed circuit board 14, and a sliding member 70 selectively switches the fixed contact 60 into the fixed contact 63 and the fixed contact 65. It is arranged in a position parallel to the upper side or lower side of the push plate 16 so as to be connected to the push plate 16. Similarly, the fixed contact 62 and the fixed contact 6
4 and a fixed contact 66 are arranged, and a sliding member 72 is correspondingly arranged. These fixed contacts 60.62.
63.64.65.66 and slide member To, 7
2 constitutes a switching mechanism for tilting either the left or right mirror of the automobile.

Each of the bridge portions M2s, 35.45 and 55 is composed of a conductive elastic body formed to have approximately the same size, and both ends of each are formed into rounded slide contacts, and each has an auxiliary leaf spring arranged inside. are provided to reinforce the elasticity of each bridge member. Furthermore, the slide member 70.7
2 is composed of a conductive elastic body with slide contacts at both ends, and forms a switching member of the changeover switch 18 as described later, and these two slide members 70, 72
are held on a slider so that they can be moved together.

An inner casing 80 having accommodation spaces for accommodating each of the above-mentioned bridge members is fixedly held on the printed circuit board 14. The inner casing 80 includes a box-shaped member 81 that accommodates the bridge members 25 and 35 and a box-shaped member 82 that accommodates the bridge members 45 and 55.

Each bridge member is housed within a corresponding box-shaped member with their sliding contacts in contact with the printed circuit board 14. Partition walls 86 and 87 are formed in the center of each of the box-shaped members 81 and 82 to separately accommodate the bridge members 25 and 35 and the bridge members 45 and 55, respectively.

The partition wall portion 86 has an inclined surface 86a on the bridge member 25 side and an inclined surface 86b on the bridge member 35 side. Similarly, the partition wall portion 87 includes inclined surfaces 87a and 87b. The inclined surfaces constituting these partition wall portions 86.87 are in contact with the inner adjacent peripheral surfaces of bridge member 25.35 and bridge member 45.55, respectively, and the lower end of each partition wall portion 86.87 is an opening 90. 91 is coming.

Furthermore, holes 93.94 and 95.96 are formed at both ends of each box-shaped member 81.82, respectively. Box-shaped member 8
Operating rods 100, 102 formed to contact the circumferential surface of the bridge member 25, 35 on the fixed contact 21, 31 side are pushed through the holes 93, 94 of No. 1, respectively. Similarly, the holes 95 and 96 of the box-shaped member 82 each have a fixed contact 41.
An operating rod 104.106 formed to contact the circumferential surface of the bridge member 45.55 on the 51 side is inserted.

Each of the actuating rods 100, 102, 104, 106 is formed to be movable relative to the inner housing 80, and one end of each is formed into a smoothly sloped surface within the box-shaped member, and is located near the slide contact of the corresponding bridge member. While being in contact with the peripheral surface, the tip faces the holes 110, 112, 114, and 116 formed on the printed circuit board 14. On the other hand, the other end of each actuating rod extends to the outside of the inner housing 80, and the push plate 16 is supported by the protruding ends of the four actuating rods 100, 102, 104, and 106. In order for the push plate 16 to be supported in a horizontal state, it is necessary to maintain the protrusion amount of each actuating rod evenly, and for this purpose, each actuating rod is provided with a corresponding box-shaped member 81.
．． Stoppers 120 and 122 that abut against the inner wall of the upper part of 82
and 124.126 are formed. These stops are shown in FIG.

The push plate 16 is provided with a pair of vertical walls 16a and 16b extending perpendicularly from a portion along the edge of the central opening 17 on the back surface of the L display section and the R display section, and the lower end thereof A tapered surface 80a formed on the back surface of the inner housing is inserted through the opening 85 of the inner housing 80 when the stopper of each actuating rod is in contact with the inner wall of the box-shaped member.

80b is fully engaged. For example, when the R display part of the push plate 16 is pressed, the lower end of the rear vertical wall 16b on the R display part side of the push plate 16 is completely separated from the tapered surface 80b on the back surface of the inner housing, and the push plate is pushed away from the display part. The side vertical wall 16a and the tapered surface 80a on the back surface of the inner housing are completely engaged with each other, and the inner housing rotates around the engaged point S.

As a result, the R display part side of the push plate 16 is lowered by a stroke l, and the inclined surfaces of the actuating rods 100 and 106 corresponding to the R display part descend while pressing the peripheral surfaces of the bridge members 25 and 55, respectively. I will do it. In this case, the bridging member 25.55 is elastically deformed, and the respective sliding contact moves away from the fixed contact 21.51 and comes into contact with the respective fixed contact 22.52. At this time, the sliding contact of the bridge member 55 is moved at a timing earlier than that of the sliding contact of the bridge member 25. Similarly, when the L display section is pressed, the push plate 16
The lower end of the vertical wall 16a is completely separated from the tapered surface 80a, and when the vertical wall 16b on the R display side and the tapered surface 80b are completely engaged, It rotates, and the L display part side moves down by a stroke l, pressing the actuating rods 102 and 104. As a result, the corresponding bridge members 35 and 45 are elastically deformed, and the bridge members 45 and 45 are elastically deformed.
The sliding contact is separated from the fixed contact 41 and fixed contact 42
come into contact with.

Further, when the U display section or the D display section is pressed, the vertical walls 16a and 16b of the push plate engage the ends of the box-shaped member 82 or the box-shaped member 81 with the tapered surfaces 80a and 80b, respectively. It is designed to rotate depending on the condition. With this, push plate 1
The U display part side or the D display part side of 6 will be lowered by a stroke l, and the inclined surface of the actuating rod 100° 102 or 104. Or 45.
While pressing the peripheral surface of 55, it descends. At this time, the bridge members 25, 35 are elastically deformed, the sliding contacts that are in contact with the fixed contact 21 are brought into contact with the fixed contact 22, the bridge members 45, 55 are also elastically deformed, and each sliding contact is in contact with the fixed contact 41. .51 and contact fixed contacts 42.52, respectively. The slide contact of the bridge member 55 is moved at an earlier timing than the slide contact of the bridging member 45. In this embodiment, the fixed contacts 30 and 31 and the bridge member 35 are used not as components of a control circuit for switching as will be described later, but as a dummy to improve the well-balanced operability of the push plate 16. It is being In practice, the symmetrical arrangement of the four bridging members and the four actuating rods is very important in the above-mentioned sense, so that no matter which direction indicator the driver presses on the push plate 16, Obtaining the same feeling of pressure will help you drive safely. In addition, the feeling when pressing the push plate 16 is tactile.
The shape of the inclined surface of each actuating rod must be appropriately selected from this point of view. This tactile feeling, that is, push plate 1
If the distance that the push plate descends when pressing 6 is exceeded, the force of the corresponding bridge member pushing up the plate becomes smaller. The contact angle between the surface and the corresponding peripheral surface of the bridge member, that is, the angle that the tangential surface makes with the printed circuit board may be formed into a shape that gradually changes within 45 degrees from the tip of the actuating rod. For example, W is the spring pressure of one bridge member, Pl is the force of one bridge member pushing up the push plate, θ is Bu θ, and r is the friction force between the printed circuit board and the bridge member or the friction between the actuating rod and the bridge member. The force p to push the push plate is p=2(P++r) =2 r+2 klcos
” is given by θ, where k is the spring constant of the bridge member, and l is the downward distance (stroke) of the push plate.
It is. Here, θ must be less than 45 degrees, and 45
If it exceeds 100 degrees, r will become large and it is inappropriate.

A control circuit for adjusting the tilting of the mirror surface, which constitutes the control switch of the present invention, is shown in FIG. Fixed contact pair 21.22: 41.42;'51.
Of the 52, fixed contacts 21, 41, and 51 are connected to the power supply 2, respectively.
Connected to the negative pole of 3, fixed contact 22.42.52
are each connected to the positive pole. Fixed contact pair 21
．． The fixed contact 20 corresponding to 22 is connected to the fixed contact 60 and connected to the fixed contact 6 via the slide member 70.
3 or 65. The fixed contact 63 is connected to one terminal of a motor A1 for tilting the left-hand mirror 120 of the automobile about a horizontal axis;
The fixed contact 65 connects the right side mirror 122 of the car to the horizontal axis.
It is connected to one terminal of motor B1 for tilting around. The fixed contact 40 corresponding to the fixed contact pair 41 , 42 is connected to the fixed contact 62 and selectively connected to the fixed contact 64 or 66 via a slide member 72 . A fixed contact 64 is connected to one terminal of a motor for tilting the left-hand mirror 120 of the vehicle about a vertical axis, and a fixed contact 66
is connected to one terminal of motor B2 for tilting the right-hand mirror 122 of the vehicle around a vertical wall. Furthermore, the fixed contacts 50 corresponding to the fixed contact pairs 51, 52 are commonly connected to the remaining terminals of the motors A+, Az, B+, Bt.

The configuration of the changeover switch 18, which is included in the control switch of the present invention and is used to tilt either the left or right mirror of the automobile, will be described.

The changeover switch 18 is connected to the support 1 fixed to the holder 15.
50 so that it can rotate. The support body 150 is 1
The lip 152 is inserted through the central opening 160 of the printed circuit board 14 and protrudes toward the fixed contact side of the printed circuit board 14, and the pair of protrusions formed on the main body of the changeover switch 18 are connected to each other. It is supported by a pair of small holes in the lip 152. The slide member 70.72 is the slider 154
When the slider 154 moves, the two sliding members 70.7
2 are designed to move at the same time. Slide member 1
An opening 156 is provided at approximately the center of the switch 54, and the shaft portion of the changeover switch 18 is inserted through this opening to connect the holder 15.
Its lower end movably engages with a guide path 158 fixed to.

That is, a compression coil spring 181 and a ball 1 are placed inside the shaft portion 180.
82 is disposed, and a portion of the ball 182 is held in a state slightly protruding outward from the lower end of the shaft portion 180. Further, a cut groove 183 is formed at the tip of the shaft portion 180 and engages with a guide path 158 fixed to the support body 150. 6th
The state shown in the figure is the neutral position, where the ball 182
is pushed into the shaft portion 180 against the elastic force of the coil spring 181, and a portion of the ball 182 is in contact with the guide path 158.

On the other hand, the operating knob 184 of the changeover switch 418 is disposed so as to pass through the central opening 85 of the inner casing 80 and protrude outward from the central opening 17 of the push plate 16 . When this operating knob 184 is rotated from the neutral position toward the R display section, the shaft section 183 pushes the opening wall of the slider 154, and the slider 154 slides toward the L display section.
Conversely, when the knob 184 is rotated toward the L display section, the slider 154 is configured to slide toward the R display section. At this time, the fixed contacts 60, 62 are connected to the fixed contacts 63, 64 or 65, 66, respectively.

Next, the operation of the control circuit using the control switch according to the present invention will be explained.

First, when tilting the mirror 120 attached to the left side of the automobile, the operating knob 184 of the changeover switch 18
is rotated toward the R display portion of the push plate 16. As a result, the fixed contacts 60 and 62 are connected to the fixed contacts 63 and 63, respectively. Since the fixed contacts 60, 62 are each connected to one terminal of motor Al and motor A2, these terminals will be connected to the negative pole of power supply 23.

Since the fixed contact 50 is always commonly connected to the remaining terminals of the motors A+, Az, B+, and Bz, the remaining terminals of the motors Al and A2 are connected to the negative pole of the power source 23. In this state, motors Al, A
All terminals of 2 are connected to the negative pole of power supply 23.

Thereafter, by pressing any display part of the push plate 16 with a finger, either the motor A + or A z can be rotated forward or reverse.

For example, when the U display part of the push plate is pushed in the direction of the arrow in FIG. It is connected to a fixed contact 22 connected to the positive pole of a power source 23. Therefore, as shown in FIG. 12, the fixed contact 63 connected to one terminal of motor A+ has a positive potential, the fixed contact 64 connected to one terminal of motor A2 has a negative potential, and the motor Since the fixed contact 50 commonly connected to other terminals A+ and -Az is held at a negative potential, as a result, the fixed contact 63 is connected to the motor A1.
A current flows from the contact point 50 toward the fixed contact 50, causing the motor A1 to rotate normally and causing the mirror 120 to tilt upward. The two terminals of motor A2 are held at negative potential and are therefore inoperative. Next, when the D indicator is pressed, the corresponding actuating rods 104 and 106 act on the bridge members 45 and 55, respectively, to elastically deform the bridge members 45 and 55. At this time, the fixed contacts 40 and 50 are connected to the fixed contacts 42 and 52, respectively, which are connected to the positive pole of the power source 23, but the sliding contact of the bridging member 55 moves at an earlier timing than the sliding contact of the bridging member 45. . Therefore, the fixed contact 63 connected to one terminal of the motor Al is held at a negative potential, the fixed contact 64 connected to one terminal of the motor A2 is held at a positive potential, and the fixed contact 50 is also held at a positive potential. Therefore, as a result, motor A1 has fixed contacts 50 to 63.
A current flows toward the mirror 120, causing the motor A to reverse, and the mirror 120 to tilt downward. The two terminals of motor A2 are at the same positive potential, so they do not operate.

Next, when you press the L display, the corresponding actuating rods 102 and 1
04 is activated, the bridge members 35 and 45 are elastically deformed, and the fixed contact 40 is held at a positive potential.

Therefore, the fixed contact 63 is held at a negative potential, the fixed contact 64 is held at a positive potential, and the fixed contact 50 is held at a negative potential, so that as a result, a current flows from the fixed contact 64 to the fixed contact 50 in the motor A2. The motor A2 is rotated normally, and the mirror 120 is tilted leftward. Motor A
The two terminals of 1 are at the same negative potential, so they do not operate. Note that when the U display section and the D display section are pressed, the bridge member 35 is elastically deformed, but since it is a dummy,
Does not contribute to switching. Similarly, change the R display section to the 10th
When pushed in the direction of the arrow in the figure, actuating rods 100 and 106 elastically deform bridge member 25 and bridge member 55, respectively. At this time, the slide contact of the bridge member 55 moves at a faster timing than the slide contact of the bridge member 25. At this time, the fixed contact 63 has a positive potential,
Since the fixed contact 64 is held at a negative potential and the fixed contact 50 is held at a positive potential, as a result, a current flows from the fixed contact 50 to the fixed contact 64 in the motor A2.
2 is reversed, and the mirror 120 tilts to the right. It can be seen that the two terminals of motor A1 do not operate because they have the same positive potential.

When tilting the mirror 122 attached to the right side of the vehicle body, the operation knob 184 of the changeover switch 18 is rotated toward the display section side of the push plate 16. After connecting the fixed contacts 60 and 62 to the fixed contacts 64 and 65, the same operation as described above is performed.

The control switch of the present invention has a push plate 16
A predetermined mirror can be tilted only while pressing any one of the four directional support parts U, D, L, and R, but the operating knob 184 can be moved to a neutral position as shown in FIG. If this is maintained, the motor can be configured so that it will not operate even if the direction indicator is pushed by mistake.

In this example, four bridge members 25°35
, 45 and 55 are formed to the same size, but this is to improve the balance of switching operations, and the bridge member 35 is essentially used as a dummy, so these structures should not be limited to.

〔Effect of the invention〕

As explained above, according to the control switch of the present invention, when the direction indicator of the push plate is pushed,
Since the first fixed contact and the second fixed contact are configured so that they are not connected to the positive pole of the power source earlier than the third fixed contact, malfunction of the motor can be prevented.
