DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described.
Will be described with reference to the drawings.First example  First, a first example of the present invention will be described with reference to FIG.
FIG. 1 is a diagram showing a circuit configuration of the driving device of the present embodiment, and FIG.
The illustration of the external appearance of the device and the structure of the switch operation section is omitted.
ing. In the following, the conventional device shown in FIGS.
The same components as those described above are denoted by the same reference numerals, and redundant description will be omitted.
Abbreviate.

The drive device of this embodiment has the same basic configuration as the device shown in FIG. 7, and is characterized in that switches 21 and 22 whose contacts are opened and closed in conjunction with the switch 14 are provided. In this case, the switch 21 is connected in parallel with the transistor 11, the C terminal is connected to the ground,
N. O terminal is connected to the ground side of one coil 2a. The C terminal is released. When the operation unit is operated in one direction in order to instruct the operation of the motor 1 in the normal rotation direction (opening direction of the window of the vehicle, etc.), one of the N. The N.O terminal (NO1) operates in conjunction with the closing operation, and the N.O. The configuration is such that the O terminal is closed.

It is to be noted that the switch 21 ensures that the coil 2 a
The switch 21 is not necessary if the switching of the transistor 11 is surely controlled in accordance with the above command even in a submerged state. Further, as shown in FIG. 2, it is possible to operate the relay 2 using the signal of the switch 14 as it is, and to omit the switch 21.

Next, in this case, the switch 22 has the C terminal connected to the power supply side terminal of the coil 3a. C terminal is connected to the power supply line E2. O terminal is coil 3
a connected to the ground terminal. When the operation unit is operated in one direction to command the operation of the motor 1 in the normal rotation direction, the switch 22 is also operated by one of the operation switches 14. The N.O terminal (NO1) operates in conjunction with the closing operation, and the N.O. The configuration is such that the O terminal is closed.

Here, the switch 22 in this case corresponds to the short-circuiting switch of the present invention. The line 23 connecting the O terminal to the ground terminal of the coil 3a constitutes a short circuit of the present invention.

[0029] That is, when the operation unit in order to command the forward direction of operation of the motor 1 is operated in the forward side, the switch 22 is operated in conjunction with the switch 14, the switch 22
C terminal and N. The coil 3 of the reverse rotation relay 3 for operating the motor 1 in the reverse rotation direction by the O terminal and the line 23
The power supply side terminal and the ground side terminal a are short-circuited, and these terminals always have the same voltage level.

As the voltage supplied to the power supply lines E1, E2, E3, a power supply voltage of a vehicle battery or the like is transformed by a transformer circuit not shown if necessary, or not shown if necessary. A predetermined voltage (for example, E3 is 5 V, E1,
E2 is 12 V).

In the driving device of the present embodiment configured as described above, when the operating section is operated to the forward rotation side , the above-described short-circuit switch is operated .
By the function of the short circuit composed of the switch 22 , the motor 1 is
Coil 3a of reverse rotation relay 3 for driving in the reverse rotation direction
Both terminals at the same voltage is short-circuited of. This is for reversal
No current can flow through the relay coil 3a of the relay 3.
Therefore, the reverse rotation relay 3 cannot operate. Accordingly
Between the contacts on the reverse rotation side of the switch 14 when submerged (C terminal-
N. Leakage occurs between O2 terminals) and reverse rotation relay 3
The operation unit is operated to the forward rotation side even if
Then, the reverse rotation relay 3 does not operate. And it

The cage motor 1 is driven in the normal rotation direction. Note that
In this embodiment, the operation unit is operated in the normal rotation direction.
The switch 21 that is turned on by operating is the forward rotation transistor 11.

Even if the transistor 11 does not turn on, this switch

it can.

[0032] Therefore, even if leakage occurs due submerged, if operated operation portion in the forward side, the motor rotates clockwise operated always only forward rotation relay 2 is, for example, applied to a vehicle window In this case, a window or the like can be reliably opened.

That is, in this case, for example, the C terminal of the switch 14 and the other N. Since a leak has occurred with the O terminal (NO.2), the reverse is erroneously performed due to a malfunction of the processing means 13.
Even if the diversion transistor 12 is driven,
Due to the above-described operation of the short circuit including the switch 22, both terminals of the coil 3a of the relay 3 are at the ground level, so that no current always flows through the coil 3a.

In this case, for example, the C terminal of the switch 22 and the N.V. Even if a leak occurs with the C terminal, the leak current naturally flows into the ground via the line 23 having a low resistance, and no current flows through the coil 3a. Further, for example, the C terminal of the switch 14 and the other N. O
Terminal to leak between the (N.O2) occurs incorrectly forward rotation transistor 11 due to malfunction of the processing unit 13
Is not driven, the ground terminal of the coil 2a is always connected to the ground via the switch 21, so that the forward rotation relay 2 is reliably operated.

That is, according to the driving device of the present embodiment, even if a water immersion accident occurs, the motor can be accurately rotated in accordance with the operation of the operation unit. The reliability of the device in the direction of opening a window or the like is improved. And if the drive device of this example is applied to a motor for opening and closing a power window of a vehicle and a motor for opening and closing a sunroof, even if a vehicle submergence accident occurs,
The opening operation of the power window and sunroof can be reliably performed, and escape from the cabin can be easily performed, thereby enhancing safety.

In the case of this embodiment, the short-circuit circuit of the present invention is connected to the short-circuit switch 22 separate from the operation switch 14.
, And the short-circuit switch 22 is operated in conjunction with the operation switch 14. For this reason, the conventional configuration as shown in FIG. 7 is simply modified by additionally connecting the small-capacity short-circuiting switch 22, and can be easily submerged without changing the configuration of the operation unit and the operation switch 14. There is an inherent effect that measures can be taken.

[0037]Second example  Next, a second example of the present invention will be described. Fig. 3 shows this example
FIG. 3 is a diagram showing a circuit configuration of the driving device of FIG. The device shown in FIG.
The same elements as those in the first example are duplicated using the same reference numerals.
Description is omitted. This example is based on the conventional circuit configuration shown in FIG.
AndReverse useFor removing the switch 5 and operating the coil 3a
Functions as a switch and as a short-circuit switch
Switch 31 which functions even if
And a short-circuit line 23 constituting a short-circuit circuit.
It is.

In this case, the switch 31 has the C terminal connected to the power supply side of the coil 3a, O terminal is power line E
2 and N.2. In which C terminal is connected to the ground side of the coil 3a via the line 23 for short-circuit, the operation unit
The operation to the reverse rotation side of N. O terminal closes (NO
(Terminal and C terminal are connected).

In the case of this example, when the operating section is operated to the normal rotation side , the switch 4 is closed, a current flows through the coil 2a, the relay 2 is operated, and the motor 1 rotates forward (a window or the like is opened). Driven in the direction). On the other hand, when the operation unit is operated to the reverse rotation side , the switch 31 is closed and its C terminal is set to N.V. O
Connected to the terminal, a current flows through the coil 3a, the relay 3 for reverse rotation operates, and the motor 1 reversely rotates (is driven in a direction in which a window or the like closes).

When the operation unit is operated to the forward rotation side (when the switch 4 is closed), the switch 3
1 and the line 23, the power supply side terminal and the ground side terminal of the coil 3a of the reverse rotation relay 3 are short-circuited, and these terminals always have the same voltage level (in this case, ground). Level).

[0041] Therefore, even if occurring leakage in the switch 31 by submersion, if operated operation portion in the forward side, the motor rotates clockwise operated always only forward rotation relay 2 is, for example, a vehicle window When it is applied to, for example, it is possible to reliably open a window or the like.

That is, in this case, for example, the C terminal of the switch 31 and the N.V. Even if a leak occurs with the O terminal,
This leak current naturally flows into the ground via the line 23 having a small resistance, and no current flows through the coil 3a. For this reason, be sure to operate only the forward rotation relay 2, reverse
The diversion relay 3 does not operate.

The present invention is not limited to the above-described embodiment, but may have various aspects and modifications. For example, in the above embodiment,
Only the coil 3a of the reversing relay 3 provided shorting circuit of the present invention is particularly improved in operational reliability of the normal rotation direction of the motor 1 (the direction of opening and window), forward
A similar short-circuiting circuit may be provided for the coil 2a of the relay 2 to improve the operation reliability of the motor 1 in the reverse rotation direction (the direction in which windows and the like are closed).

That is, in the first example shown in FIG. 1, for example, when the operation unit is turned on to the reverse rotation side (the C terminal of the switch 14 is connected to the other NO terminal (NO 2)). at the time of the state), the forward rotation relay 2 coil 2a
The power supply side terminal and the ground side terminal may be short-circuited, and a short-circuit switch and a line (for example, the same as the switch 22 and the line 23) for setting these terminals to the same voltage level may be provided.

Alternatively, instead of the switch 4 in the second example shown in FIG. 3, for example, a switch 41 as shown in FIG. 4 is provided, and its C terminal is connected to the ground terminal of the coil 2a. O terminal is connected to ground. The C terminal is connected to the power supply side terminal of the coil 2a via the shorting line 42, and when the operation unit is turned on to the normal rotation side , the N.C. A configuration in which the O terminal is closed may be used.

In this case, when the operating section is turned on to the reverse rotation side, the power supply side terminal and the ground side terminal of the coil 2a are always short-circuited, and these terminals are at the same voltage level. Therefore , the forward rotation relay 2 is always maintained in a non-operating state, and only the reverse rotation relay 3 operates.

Accordingly, in this case, even if a water immersion accident occurs, the motor can be accurately reversed in accordance with the operation of the operation unit. In this case, the motor is rotated in the reverse direction (the direction in which the window is closed). The reliability of the device is improved. However, when a vehicle or the like is submerged, the operation reliability in the direction of opening a window or the like is usually particularly required, and in this sense, such an aspect has relatively little practical significance.

The short-circuiting circuit (circuit comprising the switch 22 or 31 and the line 23) in the above embodiment has a configuration in which both ends of the relay coil are at the ground level. For example, as shown in FIG. Circuit (switch 41
And the line 42), both ends of the relay may be at the power supply voltage level.

The embodiment shown in FIGS. 3 and 4 has an operation switch of the present invention which is operated by operating an operation section;
Although the short-circuit switch of the present invention for the short-circuit is constituted by a common switch (switch 31 or 41), these may be constituted as separate switches.

For example, as shown in FIG. 5, in the conventional circuit configuration shown in FIG. 6, the short-circuit switch 22 shown in FIG.
A short-circuit circuit including a short-circuit line 23 and a short-circuit line 23 may be newly provided for the coil 3a, and the short-circuit switch 22 may be operated in conjunction with the switch 4 (operation switch). With such a configuration, an effect similar to that of the first example, in which the configuration of the conventional switches 4, 5 and the operation unit can be used as it is, is obtained.

In the first example, the special control processing by the processing means 13 has not been described.
The processing may be executed using known processing contents.

That is, for example, the current of the motor 1 is detected when the motor 1 is driven in the reverse direction (the direction for closing the window or the like), and when the current exceeds a threshold value, the pinching of the window or the like is detected. It is determined that this has occurred, and the motor 1 is forcibly driven in the normal rotation direction (a direction in which a window or the like is opened) regardless of the operation state of the operation unit (the operation state of the switch 14 or the like), and the pinch prevention processing is performed. It may be realized.

Further, the processing means 13 may have a communication control function of controlling the drive of the motor 1 (opening / closing of a window or the like) in accordance with a signal transmitted by a method such as multiplex communication.

When Ku operation unit is operated, the short-circuiting circuit, the motor differences
Cormorant direction to short-circuit the power-side terminals of the coil of the relay actuating and the ground-side terminal to be these terminals at the same voltage level.

[0055] Thus, for example, switch contact for energizing the coil of the reversing relay for operating the motor in the reverse direction, even a leak has occurred by submergence, operation
If parts are operated to the forward side, always no current flows through the coil of the reversing relay, the reverse rotation relay is maintained reliably deactivated, predetermined forward operating the motor in the forward direction
Only the output relay to operate reliably, the motor positive commanded
Operates reliably in the rolling direction. That is, according to the drive device of the present invention, even when a submergence accident occurs, the motor can be properly rotated forward or backward according to the operation of the operation unit, and the reliability of the device is improved.

Further, the short-circuit circuit is constituted by a short-circuit switch separate from the operation switch operated by operating the operation section, and the short-circuit circuit is operated in conjunction with the operation switch. If the switch is configured to operate, the submersion can be easily submerged without changing the configuration of the operation unit and the operation switch simply by modifying the conventional configuration by adding a small-capacity short-circuit switch. There is an effect that measures can be taken.

Further, if the drive device of the present invention is applied to a motor for driving an opening / closing body (power window, sunroof, etc.) of a vehicle as described in claims 3 to 5, even if a vehicle submergence accident occurs. Thus, the opening / closing operation of the opening / closing body can be reliably performed.

In particular, when the operating direction of the motor in which the short-circuiting circuit of the present invention functions is the direction in which the opening / closing body of the vehicle is opened, particularly in the direction in which the opening / closing body of the vehicle is opened. The reliability of the device is improved, and even in the event of a vehicle submersion accident, the opening / closing operation of the opening / closing member can be reliably performed, and escape from the vehicle compartment can be easily performed, thereby enhancing the safety of the vehicle.
