[Detailed Description of the Invention] The present invention relates to a multi-item switch device having multiple displays and multiple functions.

In recent years, the functions of various loads have become more diverse, and as a result, it has been desired to centralize these operation switches.

For example, the functions of automobiles have become more diversified, and their operation control methods have changed from manual to electric. As a result, various types of control switches have become more diverse and have become extremely large in quantity. There is.

Therefore, in order to drive a car safely, a large number of switches for various functions are arranged and mounted near the driver's hand, so there is a risk that the driver may easily make erroneous operations. In addition, a space corresponding to the number of operation switches is required, resulting in an increase in overall size and problems with mounting space.

The present invention was devised in view of the above-mentioned drawbacks, and its purpose is to automatically change the functions and function modes of operation switches that operate various loads by operating a mode changeover switch. It is an object of the present invention to provide a multi-item switch device that controls a large number of various loads with a small number of centralized operation switches.

and two bearing plates 9 and 10 that pivotally support both ends of the bearing plate. The mode display drum 8 is a polygonal column corresponding to the number of mode changeover switches 4a to 4d.
For example, it forms a substantially quadrangular prism shape, and each of its four sides 8
The function mode of each operation switch 1a is written and arranged in characters, symbols, figures, etc. in correspondence with the arrangement of each operation switch 1a. Further, on both axial end surfaces 8b and 8c of the mode display drum 8, a first
Pattern contacts 8 of the desired pattern as shown in the figure

A partially notched annular first pattern contact 8d as a switching pattern is arranged concentrically on the second end surface 8c, and one annular pattern as a common electrode pattern and two notched annular patterns as switching patterns are arranged concentrically. Second pattern contacts 8e, all of which are electrically conductive, are provided. There is electrical continuity between the two pattern contacts 8d and 8e. The first bearing plate 9 has operation switches 4a to 4.
Corresponding to the quantity d, for example, four fixed contacts 9a to 9d are arranged at equal intervals so as to be in sliding contact with the first pattern contact 8d to perform a switch function. The second bearing plate 10 is provided with a fixed contact 10a that is always in sliding contact and connected to the positive electrode +V of the DC power supply, and two fixed contacts 10b and 10c that are in sliding contact with the second pattern contact 8e and act as a switch. ing. The mode switching unit 5 is provided with a positioning leaf spring 1 that comes into contact with the outer peripheral surface of the mode display drum 8 in order to maintain the stopped position when the mode display drum 8 stops.
1 is installed. Further, the mode switching section 5 is set such that each side surface 8a, which is a surface on which the function mode is written on the mode display drum 8, is disposed near each operation switch 1a.

Reference numeral 12 denotes a motor drive section, which drives the motor 6 in response to switch signals from the mode changeover switches 4a to 4d and stops it in response to a motor stop command signal from the mode changeover section 5.
The motor drive unit 12 is operated by operating switches 4a to 4d.
For example, four sets of drive units 12 correspond to the quantity of
It consists of a to 12d. Each drive unit 12

and ground through resistor _R3 ,
The collector connects to the positive terminal of the DC power supply via resistor _R1 +V
The emitter is connected to the anode of the thyristor SCR. The cathode of the Cyrisk SCR is grounded via the motor 6, and the gate is connected to the positive pole +V of the DC power source via one of the operating switches 4a to 4d.

13 is a load control section, each operating switch 1a
The controller selects and controls a corresponding specific load from among the various loads in the load group 2 based on the switch signal and the function mode signal of the mode switching unit 5, and is configured by, for example, a microcomputer. More specifically, the load control section 13 selects the load group 2 from the encoded signal from the encoder 3 and the functional mode signal which is a combination of switch signals simultaneously input from the two fixed contacts 10b and 10c in the mode switching section 5. Among them, a specific load corresponding to the combination of both of the above signals is selected and controlled.

Next, the operation of the above configuration will be explained.

If the motor 6 is stopped in the state shown in FIG. A power supply voltage is applied to two fixed contacts 10b and 10c disposed at 10, and a switch signal of "1" and "1" is outputted to the load control section 13 as a function mode signal.

Now, in order to set the operation switch unit 1 to the desired function mode from this state, for example, turn the mode changeover switch 4a in the changeover switch unit 4.
Turn on. Then, in the corresponding drive unit 12a in the motor drive section 12, the gate of the thyristor SCR becomes conductive and the transistor T turns on, driving the motor 6. Correspondingly, the mode display drum 8 of the mode switching unit 5 also rotates, and when it rotates approximately 90 degrees, the fixed contact 9a disposed on the first bearing plate 9
However, when it faces the notch portion of the first pattern contact 8d, it becomes non-conductive. Then, in the drive unit 12a, the transistor T is turned OFF, so that the thyristor SCR becomes non-conductive and the motor 6 is stopped. At this time, the second
Since the phase of the end face 8c also changes by 90 degrees, only the fixed contact 10b disposed on the second bearing plate 10 is disconnected from the second pattern contact 8e and becomes non-conducting, resulting in a switch signal of "0" and a switch signal of the fixed contact 10c of "1". The switch signals are output respectively. Further, the mode display drum 8 displays the functional mode of each operation switch 1a in response to the operation of the mode changeover switch 4a.

Thereafter, by selecting and operating a desired operation switch 1a from the operation switch unit 1 while looking at the function mode displayed on the mode display drum 8, the encoder 3 outputs the encoded signal corresponding to the operation switch 1a. It is output to the load control section 13. Thus, the load control section 13 selects and controls a specific load corresponding to the combination of the encoded signal from the encoder 3 and the function mode signal from the mode switching section 5.

In the above embodiment, it is also possible to use a multiplex communication system such as optical communication for signal transmission between the operation switch unit 1 and changeover switch unit 4 and other components.

In addition to the above-mentioned embodiments, other embodiments of the changeover switch unit 4 and the motor drive unit 12, such as the one shown in FIG. 3, are also conceivable. In this configuration, the changeover switch unit 4 has a configuration of four mode changeover switches 4e to 4h, and the motor drive section 12 has a configuration of four drive units 12e to 12h mainly composed of relays. In this case,
When the mode changeover switch 4e is turned ON, the coil RC ₁ of the drive unit 12e is energized and the normally open contact is turned on.
RC ₂ and RC ₃ are turned ON and the motor 6 is driven. Then, when the coil RC ₁ becomes de-energized, the motor 6 is stopped. D is a backflow prevention diode.

As an example of the arrangement of the configurations of the above-mentioned embodiments, it may be arranged near the steering handle of a vehicle as shown in FIG.

In this case, a changeover switch unit 15 is provided in the center of the steering handle 14, and a desired number of operation switch units 17 are provided near the handle post and instrument panel 16. Each operation switch unit 17 includes a function mode display section 18 that displays the function mode of the operation switch 17a and can be switched by a motor (not shown).

Having the above configuration and operation, the following effects are achieved.
