Description

  The present invention relates to a switch device having a plurality of operation switches having different switch functions, for example, a switch device provided in an instrument panel for a vehicle.

  A switch device including a plurality of operation switches having different switch functions is widely used. As an example, a switch device that drives and controls an electric load of an automobile will be described.

As widely known, many operation switches are provided on an instrument panel of an automobile as an arrangement position that is easy for a driver to operate.
However, such an operation switch may be attached at a different position depending on the grade of the automobile or the type of the vehicle.

For this reason, it is necessary to change the wiring (wire harness) according to the grade of the automobile and the vehicle type, and it is also necessary to set a control unit for controlling the electric system load according to the switch operation in a new program. There was a problem that occurred.
Also, there are cases where all mounting holes and wiring related to the operation switches that can be mounted are set regardless of the grade or model of the car. In this case, it is necessary to match the grade and model of the car. Only the necessary operation switches are arranged, and the mounting holes where no operation switches are arranged are covered with a lid.
For this reason, in a vehicle model with a small number of operation switches, the number of parts covered with a lid increases on the instrument panel, which deteriorates the appearance and operability. There was a problem that increased.

  Therefore, nowadays, a control unit for automatically discriminating the switch function (load control instruction function) of the operation switch even when the position of the operation switch is changed is provided, and according to the switch signal of the operation switch. A switch device configured to control the load has been proposed.

  One example of this type of switch device is that a plurality of operation knobs imparted with backward force are attached to a housing so as to be able to advance and retreat, a detection switch is provided at the position in the advancing direction of each operation knob, and further, The switch device is provided with a plurality of drive pins each provided with a drive protrusion whose position is changed at the tip, and a detection switch that is opposed to the drive protrusion.

  In this switch device, the drive protrusion of each operation knob pushes a different drive pin by the advance operation of the operation knob, so that a different switch signal (binary signal) is output by each detection switch.

  Therefore, the control unit that inputs the switch signal discriminates the operation knob related to the output of the switch signal, and controls the electrical load corresponding to the operation knob.

  Another example of the above switch device is a switch device in which each of the plurality of operation switches is provided with a switch circuit in which the logical configuration is changed, and each operation switch is switched as a binary signal different depending on the switch ON. Output a signal.

  Therefore, the control unit to which the switch signal is input discriminates the operation switch corresponding to the switch signal, and controls the electric system load corresponding to the operation switch.

As described above, the switch device having the control unit for determining the switch function of the operation switch does not need to change the setting of the control unit or change the wiring even if the position of the operation switch is changed.
Therefore, the switch device having the same configuration can be mounted on the vehicle regardless of the grade of the automobile or the vehicle type.

  However, in the switch device described above, since the control unit inputs a switch signal that is a binary signal and determines the switch function, the switch function of the operation switch that outputs a switch signal other than the binary signal is determined. I can't.

  Therefore, since the switch function of the rotary switch whose switch signal is an analog signal cannot be determined, the rotary switch cannot be provided as an operation switch.

  Further, since the conventional switch device described above has a push switch configuration, it is not possible to provide a seesaw switch, a rotary switch, or the like as an operation switch in addition to the push switch. Limited.

  In the switch device of the first invention, the identification signal output from the identification signal generator of the operation switch is sent to the control unit by connecting the first connector of the operation switch to the second connector of the control unit.

  Thereby, the discriminating unit of the control unit discriminates the switch function of the operation switch connected by the connector according to the identification signal, and becomes the control mode of the load corresponding to the operation switch.

  The above-described switch function discrimination of the control unit is similarly performed for a plurality of operation switches connected to the connector, and becomes a control mode of each load corresponding to each of the operation switches having different switch functions.

  Therefore, if the operation switch connected to the connector is operated to output a switch signal, the control unit operates in the control mode corresponding to the operation switch to control the load.

  For this reason, change the position of the operation switch, change to a different switch type (push switch, seesaw switch, rotary switch, etc.), or change the number of operation switches. Even if the control unit is changed, the control unit discriminates the switch function of each operation switch and becomes the operation mode corresponding to the operation switch, so that the control unit does not need to be newly programmed.

In other words, the resistance element has a resistance value determined according to the switch function of each operation switch. By connecting the first and second connectors and supplying power to the resistance element, each operation switch has a different voltage level. An identification signal is output.
The control unit determines the switch function from the identification signal.

The identification signal generator configured as described above can be used as an operation switch for different load control because the identification signal can be changed by changing the resistance value of the resistance element even if the operation switch is the same switch type. Can do.
Further, even if the identification signal is changed in this way, the number of connection terminals of the connector does not increase.

It is a device.

  A switch device according to a seventh aspect of the present invention is a switch device comprising various operation switches such as an operation switch having a hazard switch function, an operation switch having a headlight leveling switch function, and an operation switch having a seat heater switch function. The switch device is provided in an instrument panel for a vehicle.

Next, a first embodiment in which the present invention is implemented as a vehicle-mounted switch device will be described with reference to the drawings.
FIG. 1 is a schematic configuration diagram of a switch device. Reference numeral 11 denotes a box-like operation panel attached to an instrument panel, which includes a plurality (seven in this embodiment) of square-shaped attachments to which various operation switches are attached. Holes 12a-12g are provided in a horizontal row.

  Various operation switches such as a hazard switch, a headlight leveling switch, and a seat heater switch are attached to the attachment holes 12a to 12g as being freely attachable.

In this embodiment, an operation switch 13 comprising a push switch as a hazard switch, an operation switch 14 comprising a rotary switch as a headlight leveling switch, and an operation switch comprising a seesaw switch as a seat heater switch. However, the present invention is not limited to these switches, and other various operation switches can be attached.
In the following description, the operation switches 13, 14, and 15 will be described unless otherwise specified for convenience of description.

  Each of the operation switches 13, 14, and 15 includes a switch unit that generates a switch signal, operation knobs 13 b, 14 b, and a rectangular body 13 a, 14 a, 15 a to be inserted into the mounting holes 12 a to 12 g of the operation panel 11. In addition to the light source that illuminates the symbol mark 15b, an identification signal generator for generating an identification signal indicating a switch function (load control instruction function) is provided.

Each of the operation switches 13, 14, and 15 is provided with first connectors 16a, 17a, and 18a that are integrally protruded from the distal ends of the rectangular main bodies 13a, 14a, and 15a.
The first connectors 16a, 17a, and 18a are obtained by integrally forming a large number of connection terminals on a circuit board.

3 shows the first connector 16a of the operation switch 13, the first connectors 17a and 18a of the other operation switches 14 and 15 have the same configuration.
These first connectors 16a, 17a, and 18a output a switch signal and an identification signal, and also input a power supply voltage of an illumination light source of the symbol mark.

On the other hand, switch connection units 20 a to 20 g are provided in the inner part of the mounting holes 12 a to 12 g of the operation panel 11.
The switch connection units 20a to 20g are assembled and fixed in the operation panel as the same configuration.

Further, the switch connection units 20a to 20g are provided with connector insertion holes 21a to 21g by opening the front side, and a second connector is provided on a side surface of the insertion holes 21a to 21g.
That is, by inserting the operation switches 13, 14, 15 into the mounting holes 12a, 12b, 12c of the operation panel 11 and attaching them, the first connectors 16a, 17a, 18a of the operation switches 13, 14, 15 are connected to the switch connection unit. The first connectors 16a, 17a, and 18a of the operation switches 13, 14, and 15 are electrically connected to the second connectors 16b, 17b, and 18b of the switch connection unit.

  FIG. 2 illustrates the operation switch 13 and the switch connection unit 20a. As illustrated, the second connector 16b is fixed to one side surface of the connector insertion hole 21a provided in the switch connection unit 20a.

The second connector 16b has the same configuration as the first connector 16a, and is a card edge connector in which a large number of connection terminals are integrally formed on a circuit board.
A similar second connector is provided for the connector insertion holes 21b to 21g of the other switch connection units 20b to 20g.

The above-described switch connection units 20a to 20g are connected to the controller (CPU) 22 and send the switch signal and the identification signal of each operation switch attached to the operation panel 11 to the controller 22, The power supply voltage of the illumination light source is input to each operation switch.
That is, the controller 22 is formed by the controller 22 and the switch connection units 20a to 20g.

In the switch device configured as described above, when the operation switches 13, 14, and 15 are inserted into arbitrary mounting holes (for example, 12a, 12b, and 12c) of the operation panel 11, the operation switches 13, 14, and 15 are installed in the mounting holes. A connector is connected to the switch connection unit at the back (in this case, 20a, 20b, 20c).
Accordingly, each of the operation switches 13, 14, 15 is connected to the controller 22 via the switch connection unit.

As described above, when the operation switches 13, 14, and 15 are attached to the attachment holes and connected to the switch connection unit by connectors, an identification signal is output from each of the operation switches 13, 14, and 15, as will be described later.

  Thus, the controller 22 discriminates the switch function of the operation switches 13, 14, 15 according to the identification signal, that is, the hazard switch function, the headlight leveling switch function, and the seat heater switch function. This is a control mode for the load circuit load, the head level control load, and the seat heater load.

  Therefore, if the operation knobs 13b, 14b, 15b of the operation switches 13, 14, 15 are operated in this control mode, the switch signals of these switches are sent to the controller 22, and the controller 22 becomes the switch signal. Therefore, each load is controlled.

Thus, since the controller 22 discriminates the switch function according to the identification signals of the operation switches 13, 14, 15, the mounting positions of the operation switches 13, 14, 15 with respect to the mounting holes 12a-12g are arbitrary.
For example, the operation switch 13 may be attached to the attachment hole 12f, the operation switch 14 may be attached to the attachment hole 12c, and the operation switch 15 may be attached to the attachment hole 12a. The mounting position can be exchanged with other operation switches.

For this reason, the operation switches 13, 14, and 15 are configured to be freely attachable to the attachment holes 12 a to 12 g of the operation panel 11.
Specifically, the elastic locking portions 13c, 14c, and 15c provided on the operation switches 13, 14, and 15 can be freely engaged with and disengaged from the locking portions (not shown) provided on the upper and lower surfaces of the mounting holes 12a to 12g. The operation switches 13, 14, 15 are prevented from being pulled out by being locked.

FIG. 4 is a block diagram showing an electric circuit of the switch device described above.
In the switch device shown in this figure, in addition to the operation switches 13, 14 and 15, other operation switches 24 to 27 having different switch functions are mounted in the mounting holes of the operation panel 11, and the first connector 28 a to 31 a and the second connector 28 b are mounted. The operation switches 24 to 24 are connected to the switch connection units 20d to 20g by connector connection to .about.31b.

  In this switch device, when each operation switch is attached, the controller 22 inputs an identification signal indicating a different switch function from the operation switches 13 to 15 and 24 to 27, determines the identification signal, and each operation switch The operation mode corresponding to

  Specifically, the input / output state of the port group P1 to which the switch connection unit 20a is connected corresponds to the operation switch 13, and becomes the operation mode of the load corresponding to the operation switch 13, and the switch connection unit 20b The connected port group P2 corresponds to the operation switch 14, becomes the operation mode of the load corresponding to the operation switch 14, and the port group P3 to which the switch connection unit 2c is connected corresponds to the operation switch 15. Then, the operation mode of the load corresponding to the operation switch 15 is set, and similarly, the port groups P4 to P7 are set to the operation mode of the load corresponding to the operation switches 24 to 24.

Therefore, in this operation mode, when the operation knob of any of the operation switches is operated and the switch signal is input to the controller 22, the controller 22 controls the load 32 corresponding to the operation switch. Execute.
The load control signal output from the controller 22 can be multiplexed by the multiplex communication circuit 33 and sent to the load circuit to simplify the wiring.

FIG. 5 is a circuit diagram showing a specific circuit configuration of the operation switch 13 and the switch connection unit 20a, setting of the port group P1 of the controller 22 and setting of the input / output signal level.
As shown in the figure, the operation switch 13 includes a switch portion 34 that is turned on by pushing the operation knob 13b, a light source (LED) 35 that is turned on when the switch portion 34 is turned on to illuminate the symbol mark, and an identification signal. A resistance element 36 constituting the generation unit is provided.

The resistance value of the resistance element 36 is determined in accordance with the switch function of the operation switch 13 which is a hazard switch.
The resistance element 36 is connected to the first and second connectors 16a and 16b, so that the resistance element of the switch connection unit 20a is connected via the connection terminals "9" and "10" (circled numbers). 37 and the port P07 of the controller 22.

Therefore, resistance elements 36 and 37 form a divided voltage circuit, and the divided voltage is input to port P07 as an identification signal.
As a result, the controller 22 discriminates the identification signal to enter the hazard lamp control mode, and performs port setting and input / output signal level setting as shown in the figure.

In this operation mode, when the switch section 34 is turned on, the transistor 38 of the switch connection unit 20a is turned off, so that the transistor 39 is turned on and a high switch signal is input to the port P01.
The controller 22 inputs this switch signal and executes lighting control of the light source 35 which is a hazard lamp.

  In this case, since the port P02 outputs a low signal in response to the high switch signal being input to the port P01, the transistor 40 is turned on, the light source 35 is turned on, and the light source 35 is connected to the port P03. The forward voltage is input.

  Also, in this case, the port P04 outputs a high signal, the transistor 41 is OFF, and nothing is connected to the port P05, so the port P06 is open, and nothing is connected to the port P06. The level is Low, and the transistor 42 is OFF.

FIG. 6 is a circuit diagram showing a specific circuit configuration of the operation switch 14 and the switch connection unit 20b, setting of the port group P2 of the controller 22, and input / output level setting.
The switch connection unit 20b has the same circuit configuration as the switch connection unit 20a shown in FIG.
The operation switch 14 includes a light source (LED) 35, a variable resistor 43 that varies according to the rotation of the rotor, and a resistor element 44 that generates an identification signal.

The resistance value of the resistance element 44 is determined in accordance with the switch function of the operation switch 14 that adjusts the irradiation height of the headlight.
The resistance element 44 forms a voltage dividing circuit with the resistance element 37 of the switch connection unit 20b in the same manner as described above, and inputs the divided voltage to the port P07 of the controller 22 as an identification signal.

Therefore, the controller 22 enters the adjustment mode of the headlight irradiation height by discrimination of the identification signal, and the port setting and the input / output signal level setting are performed as shown in the figure.
As a result, since the port P00 becomes a low output, the transistor 38 is turned on, the transistor 39 is turned off, and a low signal is inputted to the port P01.

In this case, the port P02 outputs a Low signal, the transistor 40 is turned on, the light source 35 is turned on, and the forward voltage of the light source 35 is input to the port P03.
Further, since the port P04 outputs a High signal, the transistor 41 is turned OFF.

Therefore, the output voltage of the variable resistor 43 corresponding to the rotor rotational position is input to the port P05, and the controller 22 controls the irradiation height adjusting mechanism of the headlight according to this output voltage.
Note that the port P06 at this time is at a low level because nothing is connected.

FIG. 7 is a circuit diagram showing specific circuit configurations of the operation switch 15 and the switch connection unit 20c, setting of the port group P3 of the controller 22, and input / output signal levels.
The switch connection unit 20c has the same configuration as the switch connection units 20a and 20b described above.

  The operation switch 15 includes a switch unit 45 that is turned on by pushing one side of the operation knob 15b and turned off by pushing the other side, and a light source (LED) 35a when the switch is turned on and a light source that shows when the switch is turned off. (LED) 35b and a resistance element 46 for generating an identification signal are provided.

  The resistance value of the resistance element 46 is determined in accordance with the switch function of the operation switch 15 which is a sheet heater switch. Similarly to the above, the divided voltage of the resistance element 46 is input to the port P07 as an identification signal. The controller 22 then becomes a control mode for generating heat from the sheet heater, and performs port setting and input / output signal setting as shown.

As a result, since the transistor 38 is ON, the switch unit 45 is ON, the transistor 39 is ON, a High switch signal is input to the port P01, and when the switch unit 45 is OFF, the Low switch signal is -Input to G01.
Therefore, the control of the heat generation of the sheet heater is executed in accordance with the switch signal input to the port P01 by the controller 22.
The rest is the same as the switch operation shown in FIGS.

  FIG. 7 shows a circuit example of the operation switch 15 which is a single circuit switch, but the ground side of the switch 45 is connected to the connection terminal “2”, and the connection terminals “7” and “8”. If a switch similar to the switch 45 is provided between the two switches, it can be implemented as a two-circuit seesaw switch that is turned off at the neutral position.

  Although specific examples of the operation switches 13, 14, and 15 have been described above, the same applies to the other operation switches 24 to 27, and the controller 22 discriminates an identification signal indicating a different switch function, and each of the operation switches. The load corresponding to is controlled.

  Further, the operation switch 13 which is a push switch and the operation switch 15 which is a seesaw switch are set so that the operation knobs 13b and 15b are automatically returned to their original positions when the operator releases the operation knobs 13b and 15b. The present invention can be implemented in the same manner with either the momentary type configured as described above or the alternate type that does not automatically return and switches alternately according to the operation of the operator.

  Further, an 8-way switch (for example, a mirror) in which a switch is connected to each of the connection terminals “1” and “2”, “3” and “4”, “5” and “6”, “7” and “8”. A control switch) can be provided as an operation switch.

This embodiment is characterized in that a switch group 47 is provided as an identification signal generation unit of the operation switch 15, and that pull-up resistors 48a to 48d are provided in the switch connection unit 20c, and the other circuits are shown in FIG. There is no change in configuration.

The switch group 47 is formed of switches 47a, 47b, 47c and 47d connected to the respective pull-up resistors 48a to 48d. The “0” signal is output from the closed switch and the “1” signal is output from the opened switch. Is output.
That is, in the switch open / close state of the switch group 47 shown in the figure, a binary signal “0100” is input to the controller 22 as an identification signal, and the controller 22 performs load control according to the switch function of the operation switch 15 as described above. To do.

  In this embodiment, the number of terminals of the first connector 18a and the second connector 18b is increased, but there is no practical problem, and other operation switches can be similarly implemented.

FIG. 9 is a schematic configuration diagram of a switch device similar to FIG. 1 shown as the third embodiment.
