Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dima-passing switch device for lighting a passing light and alternately switching between a low-beam light lighting mode and a high-beam light lighting mode.

[0002]

[Prior art]

 As a dimmer passing switch device of this type, for example, in a lever combination switch device of an automobile, particularly, in a one-position type lever combination switch device, when the lever is rotated in one direction, it is pressed at the first position. When the light for lighting is turned on and further rotated beyond the first position to the second position, the low beam light lighting mode and the high beam light lighting mode are switched alternately. In this configuration, when the lever rotation operation is stopped (when the lever is released), the lever automatically returns to the position before the operation. An example of such a structure is a switch device described in Japanese Utility Model Laid-Open No. 1-140728.

This switch device is provided with an operating member that moves linearly in association with the rotation of a lever, and is provided with a first switch that is turned on when the operating member moves to a first position, and at the same time, the operating member is provided. Is provided with a seesaw-type second switch that switches the ON / OFF state between the contacts when it moves from the first position to the second position. In this configuration, when the first switch is turned on, the passing light is turned on, and when the on / off state between the two contacts of the seesaw type second switch is switched, the low beam light lighting mode and the high beam light mode are switched on. It is designed so that the lighting mode for lights can be switched alternately.

[0004]

[Problems to be solved by the device]

 However, in the above-described conventional configuration, the seesaw-type second switch having a large number of parts is used, and when the operation member is moved to the second position, the seesaw-type second switch has two switches. Since a switching mechanism for switching the ON / OFF state between the two contacts is required, there is a problem that the overall structure of the switch device becomes complicated, the number of parts increases, and the manufacturing cost increases.

Therefore, an object of the present invention is to provide a dima passing switch device that can simplify the configuration of the entire switch device, reduce the number of parts, and reduce the manufacturing cost.

[0006]

[Means for Solving the Problems]

 The dima passing switch device of the present invention includes an operation member provided so as to be capable of reciprocating movement, and includes a first switch that is turned on when the operation member moves to the first position. A second switch that is turned on when moving from the first position to the second position is provided, and when the on signal is received from the first switch, the passing light is turned on and the second switch is turned on. Each time the ON signal is received from the switch, the light control means for alternately setting the low beam light lighting mode and the high beam light lighting mode is set.

[0007]

[Action]

 According to the above means, it is only necessary to provide the first switch that is turned on when the operating member moves to the first position and the second switch that is turned on when the operating member moves to the second position. Therefore, the seesaw-type switch and the switching mechanism for switching and operating the seesaw-type switch can be eliminated, the configuration of the entire switch device can be simplified, and the number of parts can be reduced. In this case, it is necessary to provide the light control means for lighting the passing light and alternately switching between the low beam light lighting mode and the high beam light lighting mode each time the ON signal is received from the second switch. This light control means can be easily realized by a partial function of a micro computer (for performing various controls such as light control) already installed in an automobile, and the parts can be newly added. It does not increase.

It is designed to move. An operating member 13 is provided at a lower portion of the lower housing portion 3 below the pressing member 12 so as to be vertically reciprocable. The operating member 13 is biased upward by a compression coil spring 14, and the upper end portion of the operating member 13 contacts the lower surface of the pressing member 12.

A first operation portion 15 and a second operation portion 16 are provided on the right side surface portion and the left side surface portion in FIG. 2 on the upper end side of the operation member 13, respectively. As shown in FIGS. 3 and 4, a first switch 17 and a second switch 18 are arranged in the vicinity of the first operating section 15 and the second operating section 16. As shown in FIG. 3, the first switch 17 is provided in the lower housing part 3 with a leaf spring 20 as a movable contact whose base end is attached and supported by a supporting part 19 provided in the lower housing part 3. And a fixed contact 22 attached to the supported support 21. In this case, the leaf spring 20 is configured so as to be biased by its own spring force in the direction in which the tip end contacts the fixed contact 22, and the middle portion of the leaf spring 20 is the first operation member of the operation member 13. It is designed to be placed on the upper surface of the portion 15.

As shown in FIG. 4, the second switch 18 includes a leaf spring 24, which is a movable contact whose base end portion is attached and supported by a support portion 23 provided in the lower housing portion 3, and a lower housing portion. It is composed of a fixed contact 26 attached to a supporting portion 25 provided in the portion 3. In this case, the leaf spring 24 is configured such that the tip end portion of the leaf spring 24 is biased by its own spring force in the direction in which it does not contact the fixed contact 26, and the middle portion of the leaf spring 20 serves as the second member of the operating member 13. The lower surface of the operation portion 16 is brought into contact with the lower surface.

In the case of this configuration, when the operating member 13 is located at the off position (return position) which is the position shown by the solid line in FIG. 2, as shown in FIG. 3, the first operating portion of the operating member 13 is shown. 15 pushes the leaf spring 20 upward, so that the first switch 17 is turned off. Then, when the operating member 13 is moved downward and the first operating portion 15 is moved to the passing position which is the first position indicated by the chain double-dashed line C in FIG. 3, the tip of the leaf spring 20 is fixed. , The first switch 17 is turned on. Further, the operating member 13 is moved downward, and the second operating portion 16 moves beyond the first position (passing position) indicated by the two-dot chain line D in FIG. 4 to the second position indicated by the two-dot chain line E. When moved to the dimmer position, the tip of the leaf spring 24 contacts the fixed contact 26 and the second switch 18 is turned on.

A connector portion 27 is integrally provided at a lower portion of the lower housing portion 3 on the right end side in FIG. 2, and the first switch 17 and the second switch 17 are provided in the connector portion 27. A plurality of terminals 28 derived from each contact of 18 and each contact of the turn signal switch are arranged.

Further, as shown in FIG. 5, the operation lever 6 can be rotated integrally with the lever support member 4 around a rotation center (shaft portion 5). In this case, the operating lever 6 is moved to three positions by a moderation mechanism (not shown), namely, a neutral position indicated by a solid line, a right turn position indicated by a two-dot chain line F, and a left turn position indicated by a two-dot chain line G. It is configured to be retained. In this case, when the operation lever 6 is rotated to the right turn position, the right turn contact (c-a) of the turn signal switch 29 (see FIG. 1) is turned on, and the operation lever 6 is turned to the left turn position. When it is dynamically operated, the left-turn contact (c-b) of the turn signal switch 29 is turned on.

In FIG. 1 showing the electrical configuration, a light control means, for example, a microcomputer 30, has a control function for controlling lighting of various lamps, a control function for driving and controlling a wiper motor, and the like. It stores the control program for that purpose. The microcomputer 30 receives the switch signals from the first switch 17, the second switch 18 and the turn signal switch 29, and also receives various switch signals from the lighting switch 31, the door switch 32 and the wiper switch 33. I am supposed to receive it. Then, the microcomputer 30 is configured to control the ON / OFF of the high beam headlamp 35 and the low beam headlamp 36 connected in parallel between the DC output terminals of the battery 34 via relays 37 and 38, respectively. There is.

Further, the microcomputer 30 is configured to drive and control the turn signal lamp 39, the small lamp 40, the room lamp 41, and the wiper motor 42 via drive circuits 43 to 46, respectively. It should be noted that the lighting switch 31, the door switch 32, the wiper switch 33, the turn signal lamp 39, the room lamp 40, the small lamp 41, the wiper motor 42, and the drive circuits 43 to 46 are concrete electric circuits. This is omitted and shown in the block diagram. Further, the microcomputer 30 is configured to receive various switch signals from various switches such as an operation switch and an ignition switch of the vehicle interior air conditioner and drive and control various devices such as the vehicle interior air conditioner. ing.

Next, the operation of the above configuration will be described. First, when the operation lever 6 is rotated from the return position shown by the solid line in FIG. 2 to the passing position shown by the chain double-dashed line A in FIG. 2, the operation member 13 is moved downward and the first operation portion thereof is moved. 15 moves to the passing position indicated by the chain double-dashed line C in FIG. As a result, the first switch 17 is turned on, and the on signal is given to the microcomputer 30. In response to the ON signal from the first switch 17, the microcomputer 30 turns on the relay 37 to turn on the high beam headlamp 35, thereby turning on the passing light. In this case, the high beam headlamp 35 is turned on while the first switch 17 is turned on. After that, when the turning operation of the operation lever 6 is stopped (when the hand is released from the operation lever 6), the operation lever 6 automatically returns to the return position (off position) shown by the solid line in FIG.

When the operating lever 6 is rotated beyond the passing position shown by the two-dot chain line A in FIG. 2 to the dimmer position shown by the two-dot chain line B in FIG. 2, the operating member 13 is moved further downward. Then, the second operating portion 16 moves to the dimmer position shown by the chain double-dashed line E in FIG. As a result, the second switch 18 is turned on, and the ON signal is given to the microcomputer 30. When the microcomputer 30 receives the ON signal from the second switch 18, the light lighting mode currently set in the internal memory of the microcomputer 30 is the low beam light lighting mode or the high beam light. Whether the lighting mode is the lighting mode, the high beam lighting mode is switched to the low beam lighting mode, and the low beam lighting mode is switched to the high beam lighting mode. That is, the microcomputer 30 is configured to alternately switch between the low beam light lighting mode and the high beam light lighting mode each time it receives an ON signal from the second switch 18. In the initial state (the state where the ignition switch is turned on), the low beam light lighting mode is set to the micro computer 30.

When the headlight lighting signal is received from the lighting switch 31 in the low beam light lighting mode set, the microcomputer 30 turns on the relay 38 to turn on the low beam headlamp 36. When the headlight lighting signal is received from the lighting switch 31 in the high beam light lighting mode set, the relay 37 is turned on to turn on the high beam headlamp 35.

Further, the microcomputer 30 is in a state where the low beam light lighting mode is set and a headlight lighting signal is received from the lighting switch 31, that is, the low beam headlamp 36 is lit. When the ON signal is received from the second switch 18, the light lighting mode is switched to the high beam light lighting mode, and the relay 38 is turned off and the relay 37 is turned on to turn on the high beam headlamp 35. In this case, conversely, when the high beam light lighting mode is set and the headlight lighting signal is received from the lighting switch 31, that is, the high beam headlamp 35 is lit, the second Upon receiving the ON signal from the switch 18, the microcomputer 30 turns off the relay 37 and turns on the relay 38 to turn on the low beam headlamp 36.

According to the present embodiment having such a configuration, the first switch 17 that is turned on when the operating member 13 moves to the passing position (first position) and the operating member 13 in the dimmer position (second position). Since the second switch 18 that is turned on when it is moved to the position) is provided, unlike the conventional configuration, a seesaw-type switch and a switching mechanism for switching the seesaw-type switch are unnecessary. As a result, the configuration of the entire switch device can be simplified and the number of parts can be reduced. Therefore, the manufacturing cost is significantly lower than that of the conventional configuration. In this case, it is necessary to provide the microcomputer 30 for alternately setting the low beam light lighting mode and the high beam light lighting mode each time the ON signal is received from the second switch, as well as performing the passing light lighting. Since the microcomputer 30 can use the microcomputer 30 already installed in the automobile to control the lighting of various lamps, drive control of the wiper motor 42, and the like (specifically, , Since only the partial functions of the micro computer 30 are used), the number of new parts is not increased and the manufacturing cost is hardly increased.

Although the high beam headlamp 35 is turned on while the first switch 17 is turned on in the above embodiment, instead of this, when the first switch 17 is turned on. The high beam headlamp 35 may be configured to be turned on for a predetermined set time (for example, 0.2 seconds, 0.5 seconds or 1 second). Further, in the above embodiment, the light control means is constituted by the microcomputer 30 for driving and controlling various devices such as various lamps, but it may be constituted by providing a dedicated control circuit.

A second switch is provided that turns on when moving to the second position over the line, and when the ON signal is received from the first switch, the passing light is turned on and the second switch is turned on. Since the light controller for switching between the low beam light lighting mode and the high beam light lighting mode is set each time the ON signal is received, the structure of the light control device is provided, so that the overall structure of the switch device can be simplified and the number of parts can be reduced. It has the excellent effect of being able to reduce the manufacturing cost.
