Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an operating device for a folding door mirror.

[Prior Art] In general, both the left and right side door mirrors of a car protrude laterally from the car body to a greater extent than the fender mirrors, so when entering a garage or multi-story parking lot, for example, they are lowered down to reduce the amount of protrusion. Various types of foldable door mirrors have been developed in the past.

[Problems to be Solved by the Invention] However, most of the conventional folding door mirrors were raised and folded manually.
While it is relatively easy to fold down the door mirror because it can be done from the driver's seat, it is difficult to raise and fold the passenger side door mirror from the driver's seat, so there are no passengers other than the driver. In some cases, there were problems such as the process becoming troublesome and troublesome. Additionally, some conventional folding door mirrors are electrically foldable, in which both the driver's and passenger's sides are raised and lowered by a motor; Since a motor and its drive circuit must be installed in both the seat-side door mirror and the passenger-side door mirror, the cost is high, and there are other problems such as the need to install a switch to start both motors at an appropriate location in the vehicle interior. It was hot.

The present invention solves the problems of the above-mentioned conventional devices, and provides an inexpensive operating device for a foldable door mirror that can raise and lower a door mirror on the passenger seat side without any troublesome operations. The purpose is to

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a switch for detecting a change in posture due to standing up or folding down on the driver's side door mirror, and a switch for detecting a change in posture due to standing up or folding down on the passenger side door mirror. A motor is provided, and the switch is incorporated into the drive circuit of the motor, so that in response to the manual raising or lowering of the driver's side door mirror, the passenger side door mirror is raised or lowered by the drive of the motor. .

[Function] By employing the above-mentioned means, the present invention automatically raises or lowers the passenger side door mirror by simply raising or lowering the driver's side door mirror by manual operation.

[Example] Hereinafter, an example of the present invention shown in the drawings will be described.

FIG. 1 shows an embodiment of the present invention, in which a driver's side door mirror R is attached to a mirror body 5 via a shaft 4 to a mounting base 3 attached to a driver's side door 2 of an automobile 1.
is assembled so that it can rotate between the neutral position shown by the solid line and the rearward position shown by the chain line, and there is a switch on the driver's side door mirror R that detects changes in posture as it rises and falls. SW is provided. Further, the passenger side door mirror L is attached to a mounting base 3' attached to the passenger side door 2' of the automobile 1 via a shaft 4', and the mirror body 5' is located between a neutral position shown by a solid line and a rearward position shown by a chain line. is rotatably assembled, and the passenger side door mirror L is equipped with a motor M and gears 6 and 7 for raising and lowering the mirror.
A limit switch LSN that detects when the vehicle is in the neutral position and a limit switch LSB that detects when the vehicle is in the rearward position are provided.
And the switch SW is the limit switch LSN,
It is incorporated into the drive circuit of motor M together with LSB.

FIG. 2 shows an embodiment of the drive circuit, in which SW ₁ ,
SW ₂ is a mutually interlocking switch provided on the driver's side door mirror R, and the switches SW ₁ and SW ₂
is connected to the contact N side while the driver's side door mirror R is being raised from the reclined position to the neutral position, and is connected to the contact N side when the driver's side door mirror R is being raised from the upright neutral position to the rearward position. It is designed to be connected to the contact B side during movement. M is a motor that is installed on the passenger side door mirror L and raises and lowers the passenger side door mirror L, and when a voltage is applied to the N terminal, the motor moves the passenger side door mirror L from the rearward position to the neutral position. When a voltage is applied to the B terminal, the door mirror L on the passenger seat side is driven from the neutral position to the rearward position.
LSN is a limit switch that opens the contacts when the passenger side door mirror is in the neutral position, and keeps the contacts closed at all other times. LSB is a limit switch that opens the contacts when the passenger side door mirror L is in the backward position. , a limit switch that keeps the contacts closed at all times, and D ₁ and D ₂ are diodes.

The above works as follows.

First, when the driver's side door mirror R and the passenger's side door mirror L are both in the backward position, when the driver's side door mirror R is raised to the neutral position, switches SW ₁ and SW ₂ are connected to the contact N side. ,
Therefore diode D ₁ and limit switch
Voltage is applied to the N terminal of the motor M via LSN, and the motor M raises the passenger side door mirror L toward the neutral position. When the passenger side door mirror L reaches the neutral position, the limit switch LSN opens and the motor M stops. Furthermore, when the driver's side door mirror R and the passenger's side door mirror L are both in the neutral position, when the driver's side door mirror R is lowered to the rearward position, the switches SW ₁ ,
SW ₂ is connected to the contact B side, so the diode
A voltage is applied to the B terminal of the motor M via _D2 and the limit switch LSB, and the motor M lowers the passenger side door mirror L toward the rearward position.
When the passenger side door mirror L reaches the rearward position, the limit switch LSB opens and the motor M stops. Therefore, when the driver's side door mirror R is manually raised or lowered, the passenger's side door mirror L is automatically raised or lowered in response.

FIG. 3 shows another embodiment of the drive circuit, SWN,
SWB is an automatic return switch installed on the driver's side door mirror R, and switch SWN is an automatic return switch installed on the driver's side door mirror R.
Temporarily closes before SWB, and then switches SWB
is the switch when the driver's side door mirror R is folded down.
The circuit is temporarily closed before SWN.
M, LSN, and LSB are the same motor and limit switch as in Figure 1, XN is a relay whose contact xN closes the NO circuit when it is energized, and otherwise keeps the NC circuit closed, and XB. When is energized, contact xB closes the NO circuit,
Other than that, a relay that keeps the NC circuit closed at all times.
_D1 to _D4 are diodes.

The above works as follows.

First, when the driver's side door mirror R and the passenger's side door mirror L are both in the backward position, when the driver's side door mirror R is raised to the neutral position, the switch is first pressed as the driver's side door mirror R and passenger's side door mirror L are raised.
SWN is temporarily closed, so switch SWN, diode D ₁ , relay XN, limit switch
Current flows sequentially through LSN and the NC circuit of contact xB, energizing relay Voltage is applied to the N terminal, and at this time the switch
Even if SWN automatically returns, current flows from the NO circuit of contact xN through diode _D3 to relay XN, limit switch LSN, and NC circuit of contact Voltage continues to be applied to the motor M, which raises the passenger side door mirror L toward the neutral position.
When the passenger side door mirror L reaches the neutral position, the limit switch LSN opens, the relay XN is demagnetized, and the contact xN leaves the NO circuit, so the motor M
stops. Furthermore, when the driver's side door mirror R and the passenger's side door mirror L are both in the neutral position, when the driver's side door mirror R is folded down to the rearward position, the switch SWB is first temporarily closed as the driver's side door mirror R is folded down. Therefore, the switch
Current flows sequentially through the NC circuit of SWB, diode D ₂ , relay XB, limit switch LSB, and contact xN, and relay
Voltage is applied to the B terminal of motor M through the N terminal and the NC circuit of contact xN in sequence, and even if switch SWB automatically returns at this time, the voltage is applied from the NO circuit of contact xB to relay XB and limit switch via diode _D4 . Since current flows through the NC circuit of LSB and contact xN and relay XB is self-held, voltage continues to be applied to the B terminal of motor M,
lowers the passenger side door mirror to the rearward position, and when the passenger side door mirror L reaches the rearward position, limit switch LSB opens, relay XB is demagnetized, and contact xB leaves the NO circuit, so motor M Stop. Therefore, when the driver's side door mirror R is manually raised or lowered, the passenger's side door mirror L is automatically raised or lowered in response.

FIG. 4 shows still another embodiment of the drive circuit,
SW ₁ and SW ₂ are switches provided on the driver's side door mirror R that interlock with each other.
SW ₁ and SW ₂ are designed to temporarily close and then automatically return when the driver's side door mirror R is moved up or down. M, LSN, LSB is the first,
The motor and limit switch are similar to those in Fig. 2, and XN, XB, xN, xB are relays and contacts similar to those in Fig. 2, and D ₁ to _{D 5}
is a diode, Tr is a transistor, and r ₁ and r ₂ are resistors.

The above works as follows.

First, when the driver's side door mirror R and the passenger's side door mirror L are both in the backward position, when the driver's side door mirror R is raised toward the neutral position, the switches SW ₁ ,
SW ₂ is linked and temporarily closed, and the closing of switch SW ₁ excites relay XB via the NC circuit of contact xN, which applies voltage to the emitter of transistor Tr via the NO circuit of closed contact xB. On the other hand, since the limit switch LSB is open, no voltage is applied to the cathode side of the diode _D4 , so when the switch _SW2 is closed, a voltage is applied to the base of the transistor Tr via the resistors _r1 and _r2 , Therefore, transistor Tr becomes conductive and relay XN is energized, which causes the limit switch to be activated from the NO circuit of the closed contact
LSN, motor M N terminal, B terminal, diode
By switching D ₂ and contact xN of relay XN to the NO side, a voltage is applied to the N terminal of motor M via the NC circuit of contact _{xB of} relay Even if the interlocking automatic return occurs, the _relay is activated from the NO circuit of contact
Since current flows through XN and it is self-maintained, voltage continues to be applied to the N terminal of the motor M, and the motor M raises the passenger side door mirror L toward the neutral position, and the passenger side door mirror L returns to the neutral position. When this point is reached, limit switch LSN opens, motor M stops, and relay XN is demagnetized. Furthermore, when the driver's side door mirror R and the passenger's side door mirror L are both in the neutral position, when the driver's side door mirror R is folded down to the rearward position, the switches SW ₁ and SW ₂ are activated as the driver's side door mirror R is folded down. is linked and temporarily closed, and the relay is activated by closing switch SW ₁ .
XB is energized via the NC circuit of contact xN, thereby applying a voltage to the emitter of transistor Tr via the NO circuit of closed contact xB, while the limit switch LSB is closed, so that the cathode of diode _D4 Since a voltage is also applied to the side, and therefore a voltage is applied to the base of the transistor Tr through the resistor r ₁ due to the closing of the switch SW ₂ , the transistor Tr is not conductive and the relay XN is not energized, so that the contact xB's NO

In response to this, the passenger side door mirror L automatically rises and falls.

[Effects of the Invention] Since the present invention is configured as described above, simply by manually raising or lowering the driver's side door mirror, the passenger's side door mirror can be automatically raised or lowered. The passenger side door mirror can be raised and folded down without any troublesome operations when there are no passengers other than the driver, and compared to when both the driver's side door mirror and the passenger side door mirror are electrically foldable. In addition to being able to reduce costs, there is no need to provide a switch for starting the electric drive circuit in the vehicle interior, so it has excellent effects such as not placing any restrictions on the space within the vehicle interior.
