Description

  The present invention relates to an in-vehicle composite operation switch, and is particularly mounted on an instrument panel, a steering, etc. around a driver's seat of an automobile, and is suitably used for operating audio equipment, air conditioning equipment, and the like.

  2. Description of the Related Art In recent years, automobiles have been multifunctionalized with a variety of electrical components from the viewpoints of audio equipment, air conditioning equipment, comfortable space formation, entertainment, and convenience of operation. There are an increasing number of switches for operating these electrical components. These switches are concentrated around the driver's seat, the size of the switch device is increased, the feeling of complication is increased, and the driver is liable to misoperate.

Therefore, conventionally, various composite operation switches have been proposed.
For example, Japanese Patent Laying-Open No. 2003-68170 (Patent Document 1) proposes a switch shown in FIG. 12 in which a seesaw button and a push button switch are combined.
As shown in FIG. 12A, the switch 1 is provided with a through hole 2a on the operation surface of the seesaw button 2 in a direction perpendicular to the operation surface, and the push button 3 is inserted into the through hole 2a so as to be movable up and down. When the push button 3 is pressed, the internal slider 4 moves downward and the switch unit 5 can be turned on by depressing the pressing shaft 5a of the switch unit 5.
As shown in FIG. 12B, when the left side of the seesaw button 2 is pressed, the lower left extension 2b of the seesaw button 2 can press the pressing shaft 6a of the switch unit 6 to turn on the switch unit 6, and the seesaw button 2 When the right side of the seesaw button 2 is pressed, the lower right extension 2c of the seesaw button 2 pushes down the pressing shaft 7a of the switch unit 7 so that the switch unit 7 can be turned on.

The switch 1 has a seesaw button 2 that can switch between two switch units 6 and 7 and a push button 3 that can operate a single switch unit 5, thereby reducing the size of a composite operation switch. The panel space can be reduced.
However, the composite switch has only three operating directions, and it is necessary to arrange another switch depending on the increase in the number of electric devices.

Japanese Patent Laying-Open No. 2006-12695 (Patent Document 2) proposes a composite operation switch that can be operated in multiple directions from Patent Document 1.
The composite operation switch includes a switch 100 shown in FIG. 13 and FIG. 14, and an operation body 102 is swingably held and accommodated in a case 101 and a cover 103 is covered on the upper surface. The operating body 102 is provided with a plurality of pressing portions 102A (four pressing portions 102A in the illustrated example) extending radially in the swinging direction and a shaft portion 102B extending upward, and the shaft portion 102B has A rotating body 104 is rotatably mounted, and a push button 105 is inserted in an opening on the upper surface of the cap of the rotating body 104 so as to be movable up and down. The push switches 106 </ b> A to 106 </ b> D are electrically connected and separated as the first switches along with the swinging of the operating body 102, and the second switch composed of the movable contact piece 107 and the fixed contact 108 as the rotating body 104 rotates. The dial switch as a switch is electrically connected and disconnected, and the push switch 109 as a third switch is electrically connected and disconnected as the push button 105 is pressed.
The composite switch 100 can be used for the operation of many electric devices by integrally configuring the operation elements of the five-way push switches 106A to 106D, 109 and the operation elements of the dial switch.

However, the provision of the rotating body 104 for operating the dial switch has a problem in that the operation space is increased, the structure is complicated, the number of parts is large, and the cost is increased.
Further, none of the composite operation switches 1 and 100 is provided with a mechanism for preventing an erroneous operation in which the switch in the other direction is erroneously operated during the switch operation in each direction.

JP 2003-68170 A JP 2006-12695 A

  The present invention has been made in view of the above problems, and can be operated in multiple directions, can reduce the size of the operation panel, and performs other switch operations during each switch operation. An object is to provide a low-cost in-vehicle composite operation switch that can prevent erroneous operation.

In order to solve the above-mentioned problems, the present invention is arranged on a panel attached to the surface of the case so that an operation knob can be pushed, swung up and down, and slidable left and right, and inside the case on the back side of the panel. A holder, slider, and seesaw operated by the operation knob are sequentially accommodated from the front side to the back side, and a plurality of pins are slidably accommodated inside the case on the back side of the seesaw. A plurality of switches that are selectively pressed by the plurality of pins are provided on the back side of
The holder is fitted with the operation knob on the front side through the panel, and the back side is pivotally supported by the slider so as to swing up and down, and the back side of the slider is fitted in the case, The seesaw is pivotally supported by the case so as to be swingable in the left-right direction,
The pin is selectively pressed by the push operation of the operation knob, the up and down swing operation, and the left and right slide operation, and the switch is closed by the pressed pin, and
A composite operation switch provided with a malfunction restricting unit that disables other operations during one operation among the push operation, the up and down swing operation, and the left and right slide operation of the operation knob between the operation knob and the case. providing.

  The plurality of switches provided on the back side of the case and pressed by the pins include a rubber switch provided with a plurality of movable contacts arranged at positions corresponding to the pins, and the movable contact on the back side of the rubber switch. And a printed circuit board on which a plurality of switch circuits provided with fixed contacts are provided. Or it is good also as a structure which does not provide a rubber switch and the said pin presses the switch element which has a contact on a printed circuit board.

The in-vehicle composite operation switch according to the present invention having the above-described configuration can be operated in a total of five directions by pushing one operation knob, vertically swinging operation, and left / right sliding operation. The switch circuit can be opened and closed. Therefore, the number of operation knobs provided on the operation panel can be reduced, the operation panel can be reduced in size and space can be saved, and erroneous operation due to erroneous selection of the operation knob can be effectively prevented.
In addition, although a push operation, up / down swing operation, and left / right slide operation can be performed with a single operation knob, since the operation directions are all different, a sense of moderation can be provided at each operation.
And as mentioned above, since it is a composite operation switch which can be operated in a total of five directions, since the structure is simple and the number of parts is small, the cost can be reduced.

  In addition, since the operation knob can be operated in five directions with one operation knob, the operation knob may malfunction in the other direction during operation. Since there is a malfunction restricting section that disables other operations during one operation among the dynamic operation and left / right slide operation, other operations can be mistakenly performed during each of the push operation, vertical swing operation, and slide operation. It is possible to effectively prevent erroneous operations.

Specifically, the first type pin, the second type pin, the third type pin as the plurality of pins,
With the push operation of the operation knob, the pressing protrusion protruding from the operation knob presses the first type pin,
By the swinging operation of the operation knob in the vertical direction, the holder swings in the vertical direction, and the pressing portions protruding from both the upper and lower ends of the holder press the second type pin,
The sliding movement of the operation knob in the left-right direction causes the slider to move, swings the seesaw in the left-right direction, presses either one of the left and right sides, and a pressing portion protruding from both left and right ends of the seesaw The third type pin is pressed.
In other words, since one operation knob can be operated in five directions, five pins that are pressed when operated in any of the five directions are provided, and one first type pin that is pressed during a push operation. There are two second type pins that are pressed when swinging up and down, and two third type pins that are pressed when sliding left and right, respectively, while five pins are closed when these pins are pressed. A switch is provided.

Further, as the erroneous operation restricting portion, a pair of left and right first erroneous operation restricting protrusions are provided on the back side of the operation knob, and the first erroneous operation restricting protrusion is inserted on the front side of the case when the operation knob is pushed. A pair of erroneous operation restricting portions provided with possible holes, and
A plurality of second erroneous operation restricting protrusions are provided on the surface side of the case, and a plurality of second erroneous operation restricting protrusions can be inserted into the upper and lower ends of the holder when the operation knob is pushed and vertically swung. Concave operation restriction recess,
During the push operation of the operation knob, the first erroneous operation restricting protrusion is inserted into the erroneous operation restricting portion, and the operation knob is not allowed to swing up and down and slide,
When the operation knob is swung up and down, the second erroneous operation restricting projection is inserted into the erroneous operation restricting recess so that the operation knob cannot be slid, and the tip of the first erroneous operation restricting projection is at the erroneous operation restricting portion. The push operation of the operation knob is disabled by coming out of the hole and hitting the tip surface of the erroneous operation restricting portion,
During the sliding operation of the operation knob, the second erroneous operation restriction protrusion and the erroneous operation restriction recess are not displaced from each other in the left-right direction, the operation knob cannot be swung up and down, and the first erroneous operation restriction The tip of the protrusion is out of the hole of the erroneous operation restricting portion and abuts against the tip surface of the erroneous operation restricting portion, thereby making it impossible to push the operation knob.

  As described above, according to the present invention, a single operation knob can be operated in five directions, ie, a push operation, a vertical swing operation, and a left / right slide operation, and five switch circuits can be turned on / off. Therefore, since many electric devices can be operated with one operation knob, the number of operation knobs attached to the operation panel can be reduced, the operation panel can be reduced in size and space can be saved, and the driver can operate it. It is possible to effectively prevent erroneous operation of the electric device due to wrong selection of the knob.

  Also, during each operation of the operation knob push operation, up-and-down swing operation, and left-right slide operation, the operation knob can be operated in the other direction, so that a malfunction control unit is provided so that the operation of the desired electrical device can be performed. It is possible to effectively prevent an erroneous operation that causes a switch operation of different electrical devices. Furthermore, since the composite operation switch of the present invention has a simple structure and a small number of parts, the cost can be reduced.

The pressing part 61 to push is provided in a protruding manner.

Next, the assembly structure of the switch 10 composed of the above parts will be described.
The operation knob 11 is inserted into the operation knob mounting hole 20 sandwiched between the left and right beams 21 of the panel 12, the operation knob 11 is fitted to the holder 41, and the locking claw 19 of the operation knob 11 is locked to the holder 41. The operation knob 11 and the holder 41 are assembled via the panel 12 by being inserted and locked in the recess 48.

A bearing hole 59 of a seesaw 43 is fitted to the seesaw shaft 35 of the case 13 on the surface side of the case 13, and the seesaw 43 is pivotally supported by the case 13 so that the seesaw can swing in the left-right direction. Moreover, as shown in FIG. 5 etc., the pin 27 (27A-27E) is inserted and accommodated in the pin through-hole 25 and the pin accommodating part 26 of case 13 so that sliding is possible in an axial direction.
A printed circuit board 15 having a rubber switch 14 fixed to the front surface side is disposed on the back surface side of the case 13, and a screw (not shown) is inserted into the screw hole 34 of the printed circuit board 15. The rubber switch 14 and the printed circuit board 15 are fixed to the case 13 by screwing into the bolt holes 30 a of the fastening fixing portion 30.
The rubber switch 14 is temporarily fixed by fitting a protrusion (not shown) provided on the back surface of the rubber switch 14 into a temporary fixing hole (not shown) provided on the printed circuit board 15.

  The case 13 and the panel 12 are fixed to each other by passing a screw (not shown) through the screw hole 31 of the case 13 and screwing the screw into the screw hole of the screw fastening portion 22 of the panel 12. A bottom wall 52 of the slider 42 is fitted and fixed to the case 13.

Next, the operation of the switch 10 assembled and configured as described above will be described.
When the operation knob 11 is pushed, as shown in FIGS. 4A and 4B and FIGS. 5A and 5B, the pressing protrusion 17 protruding from the center of the operation knob 11 presses the pin 27A. 27A can press the movable part 32A of the rubber switch 14 to bring the movable contact 33 of the movable part 32A into contact with the fixed contact of the printed circuit board 15, thereby closing the switch circuit.

  Further, at the time of this push operation, as shown in FIG. 5 (B), the tip end portion of the first erroneous operation restricting projection 18 projecting from the operation knob 11 in the hole 28a of the misoperation restricting tubular portion 28 projecting from the case 13. Since the first erroneous operation restricting protrusion 18 and the erroneous operation restricting cylinder portion 28 are fitted, the sliding operation in the left-right direction and the vertical swing operation of the operation knob 11 can be effectively restricted.

When the operation knob 11 is swung up and down, for example, when swung downward as shown in FIGS. 7A and 7B, the holder 41 integrally assembled with the operation knob 11 is moved up and down. It swings downward with 49 as a fulcrum. Accordingly, the pressing portion 50 on the lower side of the holder 41 presses the pin 27C, the pin 27C presses the movable portion 32C of the rubber switch 14, and the movable contact 33 of the movable portion 32C contacts the fixed contact of the printed circuit board 15. Then, the switch circuit is closed.
Similarly, when the operation knob 11 is swung upward, the holder 41 swings upward, the pressing portion 50 on the upper side of the holder 41 presses the pin 27B, and the pin 27B moves the rubber switch 14. The part 32B is pressed.

Further, during this up-and-down swing operation, as shown in FIGS. 8A and 8B, the first erroneous operation restricting projection 18 of the operation knob 11 is disengaged from the position of the fitting hole 28a of the erroneous operation restricting cylinder portion 28. Even if the knob 11 is to be pushed, the distal end portion of the first erroneous operation restricting protrusion 18 interferes with the distal end peripheral portion of the erroneous operation restricting cylindrical portion 28, so that the push operation cannot be performed.
Further, during the up-and-down swing operation, as shown in FIGS. 9A and 9B, the second erroneous operation restricting projection 29 protruding from the case 13 is inserted into the erroneous operation restricting recess 51 of the holder 41, Thus, the holder 41 cannot be slid in the left-right direction, and the operation knob 11 integrated with the holder 41 cannot be slid.

When the operation knob 11 is slid, for example, when it is slid leftward as shown in FIGS. 11A and 11B, the slider 42 attached to the holder 41 attached to the operation knob 11 is operated. Slide and move to the left together with the knob 11. With the movement of the slider 42, the left corner 52 a of the bottom wall 52 of the slider 42 pushes the inclined inner surface of the left wall 58 of the seesaw 43 outward, and the seesaw 43 tilts to the left with the seesaw shaft 35 as a fulcrum. The pressing portion 61 protruding outside the left wall 58 of the seesaw 43 presses the pin 27D, the pin 27D presses the movable portion 32D of the rubber switch 14, and the movable contact 33 of the movable portion 32D fixes the printed circuit board 15. Contact the contact to close the switch circuit.
Similarly, when the operation knob 11 is slid in the right direction, the seesaw 43 is tilted to the right to press the pin 27E, and the pin 27E presses the movable portion 32E of the rubber switch 14.

  At the time of the slide operation, as shown in FIG. 11B, the first erroneous operation restricting protrusion 18 of the operation knob 11 is disengaged from the position of the hole 28a of the erroneous operation restricting cylinder portion 28. The distal end portion of the first erroneous operation restricting protrusion 18 interferes with the peripheral edge portion of the distal end of the erroneous operation restricting cylindrical portion 28, and the push operation cannot be performed. Furthermore, since the second erroneous operation restricting projection 29 protruding from the case 13 and the erroneous operation restricting concave portion 51 provided in the holder 41 are displaced from the opposing positions, the operation knob 11 cannot be swung up and down.

  Before the operation knob 11 is slid, as shown in FIG. 11A, the second erroneous operation restricting projection 29 and the erroneous operation restricting recess 51 are opposed to each other. By being inserted into 51, the holder 41 can be pushed and swung up and down with respect to the case 13, and the operation knob 11 assembled integrally with the holder 41 can also be pushed and swung up and down. .

  As described above, the switch 10 can operate the operation knob 11 in five directions, ie, push operation, vertical swing operation, and left-right slide operation, and the single switch 10 can be used to electrically connect the five switch circuits. Separation can be performed selectively. Therefore, since the number of operation knobs provided on the operation panel can be reduced, the operation panel can be reduced in size and space, and the driver can operate the operation knob different from the desired operation knob. Can also be prevented.

In addition, since other switch operations cannot be performed during each of the push operation, the vertical swing operation, and the slide operation, it is possible to prevent an erroneous operation from occurring by performing another switch operation during each operation.
Furthermore, since multi-directional operation is possible, the structure is simple and the number of parts is small, so that the cost can be reduced.

  In the above-described embodiment, the movable portion of the rubber switch is pressed by the pin 27 to close the switch, but the switch element having a contact point on the printed board may be pressed without providing the rubber switch.
