The operation of the door mirror device configured as described above will be described in detail with reference to a time chart shown in FIG. First, when the ignition switch 16 is in the ON state ((a) in the figure) and the operation switch 11 is pressed while the door mirror is in use, an ON signal is input to the basic control circuit 12 ((b) in the figure). ), A storage signal is output from the basic control circuit 12 to the coil 14d of the storage relay 14 (FIG. 3 (c)). The output of this storage signal is output from the basic control circuit 1
2 is maintained for a certain period of time by a timer relay incorporated in the device. The certain time here is a time slightly longer than the time required for the door mirror to move from the use state to the storage state.

Then, the storage relay 14 is excited to connect the normally open terminal 14a to the common terminal 14c. From the battery 15, the normally open terminal 14a, the common terminal 14c, the actuator 60, the common terminal 13c, Since a storage current flows to the ground via the normally-closed terminal 13b, the actuator 60 is driven and the door mirror is in the storage state. At this time, the storage current is transferred to the holding unit 22a of the extension control circuit 22 through the connector 50.
, This state is held by the holding unit 22a (FIG. 9E).

Next, when the operation switch 11 is pressed again, a 0N signal is input to the basic control circuit 12, and a return signal is output from the basic control circuit 12 to the coil 13d of the return relay 13 ( FIG. The output of the return signal is held for a certain period of time by a timer relay incorporated in the basic control circuit 12 like the storage signal. In this manner, the basic control circuit 12 alternately outputs a storage signal and a return signal, such as a storage signal, a recovery signal, and a storage signal, each time the ON signal of the operation switch 11 is input.

Then, the return relay 13 is excited, the normally open terminal 13a and the common terminal 13c are connected, and a return current flows through the actuator 60 in a direction opposite to the storage current.
Is driven in reverse to put the door mirror in use. At this time,
Since the return current is input to the holding unit 22a of the extended control circuit 22 through the connector 50, the holding unit 22
This state is maintained by a ((f) in the figure).

Thereafter, when the ignition key is removed, an OFF signal of the ignition key switch 21 is input to the ignition key discriminating section 22b (FIG. 9 (g)). At this time, a return signal is held in the holding unit 22a, and it is known that the door mirror is in use. Therefore, the driving unit 22c determines that the door mirror should be stored, and outputs the automatic operation signal output means. The storage command signal is output to the base of the 23 transistor 23a. Then, the transistor 23a is turned ON for a predetermined time (for example, 0.5 second), and the operation switch 11 is turned ON.
An automatic operation signal is output to the input lines of the N and OFF signals (FIG. 9 (h)).

The automatic operation signal is output from the operation switch 1
1 is directly input to the basic control circuit 12 as the ON signal, the basic control circuit 12 outputs a storage signal to the storage relay 14, and the same as when the operation switch is pressed in the use state of the door mirror. Is performed (FIG. 10C).

When the ignition key is inserted in this state, the ignition key switch 21 is turned on.
A signal is input to the ignition key discriminating section 22b (FIG. 9 (g)). At this time, since the holding signal is held in the holding unit 22a and it is known that the door mirror is in the stowed state, the driving unit 22c determines that the door mirror should be returned and outputs the automatic operation signal output means. 23
A return command signal is output to the base of the transistor 23a. Then, the transistor 23a is turned on for a certain period of time, and an automatic operation signal is output to the input line of the ON / OFF signal of the operation switch 11 (FIG. 9 (h)). Then, in the retracted state of the door mirror, the returning operation is performed in the same manner as when the operation switch is pressed.

After that, the operation switch 11
Is pressed and the door mirror is retracted, and then the ignition key is pulled out, the holding unit 22a holds the storage signal, and it can be recognized that the door mirror is in the retracted state. The storage command signal is not output to the automatic operation signal output means 23, and the power of the battery 15 is not wastefully consumed.

As described above, in this door mirror device,
If the ignition key is inserted while the door mirror is in the retracted state, the automatic operation signal is output from the extended control circuit 22 and the door mirror is automatically returned to the use state. It is possible to prevent a situation in which the vehicle travels with the vehicle running. Conversely, if the ignition key is removed while the door mirror is in use, an automatic operation signal is output from the extended control circuit 22 and the door mirror is automatically retracted. It is effective for

FIGS. 3 and 4 show another embodiment.
This door mirror device includes a basic control unit and an extended control unit in the same manner as the door mirror device. Since the basic control unit has the same configuration as that of the embodiment, the description thereof will be omitted, and the extended control unit will be described. . Note that the configuration of the extended control means is not largely different, and therefore the same components are denoted by the same reference numerals and description thereof will be omitted.

The extended control means 30 of the door mirror device
The extension control means 20 of the above-described embodiment allows the drive unit 22 of the extension control circuit 22 to operate based on the insertion and removal of the ignition key.
c is outputting an automatic operation signal, whereas the driving unit 32c of the extended control circuit 32 outputs an automatic operation signal based on the vehicle speed of the automobile, which is different from the extended control means 20 of the embodiment.

Specifically, as shown in FIG. 3, a vehicle speed sensor 31 for detecting the vehicle speed of the vehicle is provided, and the extended control circuit 30 detects the vehicle speed by using the vehicle speed sensor 31 instead of the ignition key discriminating unit 22b. A vehicle speed determination unit 32b to which vehicle speed data is input is provided.

The vehicle speed judging section 32b judges whether the vehicle speed inputted from the vehicle speed sensor 31 is higher than a preset vehicle speed, and outputs the information to the driving section 32c. Based on the information on the state of the door mirror input from the holding unit 22a and the information on the vehicle speed from the vehicle speed discriminating unit 32b, the driving unit 32c makes the actual vehicle speed smaller than the set value despite the door mirror being in the retracted state. Only when it is larger, a return command is output to the automatic operation signal output means.

Therefore, even when the driver drives the vehicle with the door mirror retracted, if the vehicle speed exceeds a predetermined speed, the basic control means operates based on the automatic operation signal in the same manner as described above. The door mirror is automatically used.

As shown in FIG. 4, in this door mirror device, when the vehicle is driven while the door mirror is in use, even if the vehicle speed exceeds a set value, the drive unit 32c
Does not output a return command to the automatic operation signal output means, and does not wastefully consume the power of the battery 15 as in the embodiment. FIG. 4 does not show a time chart of ON and OFF of the ignition switch 16, but the ignition switch is in an ON state.

FIGS. 5 and 6 show still another embodiment. This door mirror device includes a basic control unit and an extended control unit similarly to the door mirror device, and the basic control unit has the same configuration as that of the embodiment,
A description thereof will be omitted, and the extension control means will be described. Note that the configuration of the extended control means is not largely different, and therefore the same components are denoted by the same reference numerals and description thereof will be omitted.

The extended control means 40 of the door mirror device
While the extension control means 20, 30 of the above-described embodiment outputs the automatic operation signal while the operation units 22c, 32c of the extension control circuits 22, 32 output the automatic operation signal based on the insertion / removal of the ignition key or the vehicle speed of the automobile, In that the automatic control signal is output based on both the key insertion and removal and the vehicle speed,
30.

More specifically, as shown in FIG. 5, a vehicle speed sensor 31 for detecting the speed of the vehicle is provided, and an extended control circuit 40 is provided with an O / O switch of the ignition key switch 21.
N, OFF signal is input and the vehicle speed sensor 31
An ignition key / vehicle speed discriminating unit 42b to which the vehicle speed data detected by the vehicle is inputted is provided.

This ignition key / vehicle speed discriminating section 42
b indicates ON, O of the ignition key switch 21;
Based on the FF signal, it determines whether the ignition key is inserted or removed, and determines whether the vehicle speed input from the vehicle speed sensor 31 is higher than a predetermined vehicle speed, and outputs the information to the drive unit 42c. This drive unit 42
c is based on the information on the state of the door mirror and the information on the ignition key and the vehicle speed input from the holding unit 22a, and outputs a storage command to the automatic operation signal output means 23 when the ignition key is removed while the door mirror is in use. At the same time, the return command signal is output to the automatic operation signal output means 23 only when the actual vehicle speed is higher than the set value while the door mirror is in the retracted state.

Therefore, as shown in FIG. 6, when the ignition key is removed while the door mirror is in use, the same as in the first embodiment based on the automatic operation signal output from the automatic operation signal output means 23. When the basic control means 10 is operated and the door mirror is automatically retracted, and when the vehicle speed of the vehicle exceeds a predetermined speed even when the driver drives the vehicle with the door mirror retracted, the automatic operation signal is output. Based on the automatic operation signal output from the output means 23, the basic control means 10 is operated and the door mirror is automatically used as in the case of the second embodiment. For this reason, when the vehicle is to be discharged from a very narrow garage at a low speed, the door mirror does not return to the use state even when the ignition key is inserted, and it is possible to prevent the door mirror from being damaged when leaving the vehicle.

In each of the above embodiments, the basic control means 10
And the extension control means 20 are detachably connected via a connector 50. By detaching the extension control means 20, as shown in FIG. 7, the door mirror is stored and returned based on the operation of the driver. It can be used as a door mirror device having only the basic functions of In this case, as shown in FIG. 8, when the ignition switch 16 is on and the door mirror is in use,
When the operation switch 11 is pressed, as described above,
A storage signal is output from the basic control circuit 12 to the storage relay 14, and the door mirror is stored. Thereafter, when the operation switch 11 is pressed again, the basic control circuit 1
A return signal is output to the return relay 13 from 2 to return the door mirror to the use state. When the ignition switch 16 is in the OFF state, even if the operation switch 11 is pressed, the operation of the operation switch 11
Since the N signal is not output, the door mirror is not stored or returned.

On the other hand, when the door mirror device having only the basic functions described above is provided with an extended function for storing and returning the door mirror based on the ignition key and the vehicle speed as described above, the connector 50 is required. It can be easily realized simply by connecting necessary extension control means 20, 30, and 40 via the interface.

[0043]

As described above, the door mirror device according to the present invention employs a configuration in which the basic control means and the extended control means are connected so as to be freely detachable via the connecting portion. It is not necessary to manufacture in an integrated state, and it is possible to prevent the manufacturing process of the door mirror device from being complicated, and to connect the basic control unit itself to the door mirror device having only the basic control unit by simply connecting the extended control unit. An automatic storage / recovery function or an automatic return function can be easily added without replacement.
