Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a drive control switch device for adjusting a remote control mirror of an automobile or the like in a desired direction.

[Conventional technology]

Conventionally, in an automobile or the like, when adjusting the direction of the remote control mirror, two drive motors for swinging the remote control mirror vertically or horizontally are provided, and the operation panel in the vehicle is shown in FIG. Such a drive control switch device 1 is provided.

In the switch device 1, the switches 2 and 3 are switches for swinging a remote control mirror (not shown) upward or downward, respectively, and the switches 4 and 5 are also provided.
Are switches (see FIG. 2 (B)) for swinging leftward or rightward, respectively. Although there are a pair of left and right remote control mirrors, only one remote control mirror will be described for the sake of simplicity.

When the direction of the remote control mirror is adjusted by such a switch device 1, by pressing one of the switches 2, 3, 4 or 5 corresponding to the direction to be changed with a finger, the switch 2, 3, 4 or 5 is changed. Is turned on, the two drive motors are respectively driven appropriately, and the remote control mirror can be adjusted in a desired direction.

[Problems to be solved by the invention]

However, the switch device 1 configured as described above
In the above, since the entire switch device 1 is configured to be relatively small, the switches 2, 3, provided on the surface thereof are
The operation parts 4 and 5 are arranged close to each other. For this reason, when a finger is extended to operate one switch 2, 3, 4 or 5, if the finger also touches another switch adjacent to the switch which is to be operated, this switch is also turned on at the same time. It will be. For example, if you try to swing the remote control mirror up and down,
Since the remote control mirror is also swung in the left-right direction, the desired adjustment of the remote control mirror cannot be performed. Especially, when the above operation is performed while the vehicle is driving, the switch is erroneously operated. As a result, the remote control mirror is inadvertently adjusted in an unintended direction, which is a safety issue.

[Purpose of device]

In view of the above points, the present invention prevents a motor from being driven by another switch when one switch is turned on even when another switch is operated. An object is to provide a control switch device.

[Means and Actions for Solving Problems]

According to the present invention, according to the present invention, two motors to be driven in the horizontal direction and the vertical direction are connected to a motor when a signal is input to either one of the two input terminals. Motor driving I to which + voltage is supplied from the output terminal corresponding to the input terminal of the two output terminals
C is provided, a constant voltage is applied to each input terminal of this motor driving IC via a switch, and this constant voltage is grounded via a switching circuit. This is achieved by a drive control switch device in which the voltage of the input terminal is applied as a trigger voltage of a switching circuit associated with the other motor drive IC.

According to this invention, for two motors to be drive-controlled, when a switch is turned on to drive one motor, a constant voltage is applied to one input terminal of the motor drive IC via this switch. Since a predetermined + voltage is supplied from the corresponding output terminal of this motor driving IC and the other output terminal is at zero potential, the motor rotates in the normal or reverse direction and the other switch is turned on. Similarly, the motor rotates in the reverse or forward direction in the same manner, but at the same time when the switch is turned on, a constant voltage is input as a trigger voltage to the switching circuit associated with the other motor driving IC. When turned on, the constant voltage is released to the ground, so even if the switch associated with the other motor driving IC is turned on, this mode The input terminal of the driving IC from the constant voltage is not applied, the other motor can not be driven. Therefore, even if one finger accidentally touches another switch when trying to operate one switch, the two motors are driven simultaneously and the driven control object, such as the remote control mirror, moves horizontally and vertically. Proper drive control can be performed without being driven at the same time.

〔Example〕

Hereinafter, the present invention will be further described based on the embodiments shown in the drawings.

FIG. 1 shows an embodiment of a drive control switch device according to the present invention. This drive control switch device 10 is
First motors 12 and 22 for vertically swinging a pair of left and right remote control mirrors 11 and 21 of the vehicle,
The second motors 13 and 23 for swinging the remote control mirrors 11 and 21 in the left-right direction are for driving control, and the first motors 12 and 22 and the second motor 1 are provided.
A drive control circuit is individually configured for each of 3 and 23.

The first motor 12, 22 or the second motor 13,
23 for the motor drive IC 14 or 2 respectively
4 two output terminals 14a, 14b or 24a, 24
b, the output terminal 14a directly, the output terminal 24a via the changeover switch 15a, and the output terminals 14b, 24b.
Are connected to each other as shown in the drawings via the changeover switch 15b.

Here, the changeover switches 15a and 15b are for changing over the left and right remote-control mirrors 11 or 22 to be drive-controlled, and are designed to work together. A constant voltage power source is connected to the input terminals 14c, 14d or 24c, 24d of the motor driving IC 14 or 24 via switches 16, 17 or 26, 27, respectively, and the input terminals 14e, 24e are grounded. ing.
Here, the switch 16 is for upward, the switch 17 is for downward, or the switch 26 is for right, and the switch 27 is for left.

Further, the constant voltage power source side of the switches 16, 17 or 26, 27 is provided with a switching circuit 18 formed of transistors,
It is grounded via 28. This switch 16,1
The motor drive ICs 14 and 24 of 7 or 26 and 27 are connected to the other motor drive IC 2 via backflow prevention diodes 19a and 19b or 29a and 29b, respectively.
It is input as a trigger voltage to the switching circuits 28 and 18 related to 4 or 14.

The embodiment of the drive control switch device according to the present invention is configured as described above, and the switches 16, 17, 26, 2 are provided.
When none of 7 is turned on, each motor drive IC
14, 24 output terminals 14a, 14b, 24a, 24b
Is zero potential and the motors 12 and 13 are not driven.

Here, for example, when it is desired to drive and control the left remote control mirror 11 upward, when the switch 16 is operated to be turned on, a constant voltage is applied via the switch 16 to the motor drive I.
It is input to the input terminal 14c of C14, whereby the motor driving IC 14 is output from the output terminal 14a of a predetermined +
Since a voltage is output and the output terminal 14b has a zero potential, a positive voltage is applied to the motor 12 for vertically driving the remote-control mirror 11 via the switch 15b, and the motor 12 rotates in the forward direction, whereby the remote controller is driven. The mirror 11 is driven and controlled in the upward direction.

Here, when the switch 26 or 27 is further turned on while the switch 16 is turned on, the trigger voltage is applied to the switching circuit 28 via the diode 19a by turning on the switch 16. , The switching circuit 28 is on, so the constant voltage is released to earth and the switch 26 or 27
Input terminal 24 of the motor drive IC 24
Since the constant voltage is not applied to c and 24d, no voltage is output from the output terminals 24a and 24b of the motor driving IC 24, so that the motor 13 cannot be driven.

When the switch 17 is turned on, the motor drive I
The + voltage is output from the output terminal 14b of the C14 and the motor 12 is rotated in the reverse direction.
Will be driven downward. In this case, the motor 13 cannot be driven even if the switches 26 and 27 are turned on in the same manner.

Also, when the switch 26 or 27 is turned on without turning on the switches 16 and 17, the motor 1 similarly
3, the remote control mirror 11 is driven and controlled to the right or left, and even if the switches 16 and 17 are turned on in this state, the motor 12 cannot be driven.

When it is desired to drive and control the right remote controller mirror 21, the drive control of the motors 22 and 23 can be performed in exactly the same manner by switching the changeover switches 15a and 15b to the opposite side of the drawing.

The switches 16 and 17 or the switches 26 and 2
7 are turned on at the same time, the output terminals 14a, 14b or 24 of the motor driving ICs 14 and 24, respectively.
Since both a and 24b have the predetermined + voltage, the voltage applied to the motors 12, 13, 22, and 23 becomes zero, and the motors stop.

[Effect of device]

As described above, according to the present invention, when a signal is input to either one of the two input terminals for two motors to be driven and controlled in the horizontal direction and the vertical direction, the motor is connected to the motor. A motor drive IC to which + voltage is supplied from the output terminal corresponding to the input terminal of the two output terminals
A constant voltage is applied to each input terminal of each motor via a switch, and this constant voltage is grounded via a switching circuit, and the voltage of the input terminal of each motor driving IC is applied to the other motor driving IC. Since the drive control switch device is configured so as to be applied as the trigger voltage of the related switching circuit, when the switch is turned on to drive one of the two motors to be drive-controlled, the switch is turned on. Since a constant voltage is applied to one input terminal of the motor driving IC via the motor, a predetermined + voltage is supplied from the corresponding output terminal of the motor driving IC, and the other output terminal has zero potential. Therefore, the motor rotates normally or reversely. Similarly, when the other switch is turned on, the motor rotates in the reverse or forward direction in the same manner, but at the same time, when the switch is turned on, a constant voltage is input to the switching circuit associated with the other motor driving IC as a trigger voltage. As a result, the switching circuit is turned on and the constant voltage is released to the ground. Therefore, even if the switch related to the other motor driving IC is turned on, the switching circuit is connected to the input terminal of the motor driving IC. Since no constant voltage is applied to the other motor, the other motor cannot be driven.

Therefore, even if one finger accidentally touches the other switch while trying to operate one switch, the two motors are simultaneously driven and the driven control object, such as the remote control mirror, simultaneously moves in the horizontal and vertical directions. Therefore, proper drive control can be performed without being driven.

Thus, according to the present invention, when one switch is turned on, even if another switch is operated, the motor cannot be driven by the other switch, which is extremely excellent. A drive control switch device can be provided.
