and a switching transistor 62.

The overvoltage detection mechanism 58 also includes control transistors 64 and 66.

Note that the control IC 60 has a well-known circuit configuration as shown in FIG.

Also, terminal 2 is a set terminal, and its input is
When the state changes from Hi to Lo, the output terminal 3 becomes Hi.

Terminal 4 is a reset terminal, and its input is Hi.
When the output terminal 3 changes from the state to the Lo state, the output terminal 3 becomes the Lo state.

Terminal 5 is a reference voltage detection terminal, and terminal 6 is a comparison voltage detection terminal. When the voltage detected at terminal 6 reaches the voltage detected at terminal 5, output terminal 3
It becomes Lo state.

Terminal 7 is a discharge terminal, and output terminal 3 is Lo
It is grounded when the state is reached.

The control unit 54 of the electric ashtray device according to this embodiment is configured as described above, and its operation will be explained next.

First, in the circuit shown in FIG.
2 and 44 are in contact with the fixed contacts 46 and 50, respectively, and it is understood that the ashtray portion 14 is in the stored state. In this state, the control unit 54 is connected to the power supply (+B).
When more voltage is applied, the capacitor 68 of the motor control mechanism 56 is charged, and a trigger voltage is applied to the reset terminal 4 of the control IC 60. For this reason,
The output terminal 3 of the control IC 60 becomes Low level, and the switching transistor 62 whose base is connected to the output terminal 3 is turned off.

As a result, no current is applied to the motor 20,
It is in a stopped state.

Then, when the operator turns on the switch button 24 from this state, the set terminal 2 of the control IC 60 changes from the Hi state to the Lo state, and as a result, the output terminal 3 becomes the Hi state. Then, the switching transistor 62 is controlled to be on, and current flows from the power supply (+B) to the ground terminal via the fixed contact 50, the movable contact 44, the motor 20, the movable contact 42, the fixed contact 46, and the switching transistor 62, and the motor 2
0 rotates.

Therefore, the ashtray portion 14 is driven to be drawn out.

Then, when the ashtray section 14 reaches the end of the drawer,
The switching knob 36 shown in FIG. 1 comes into contact with the switching piece 38, and the switching knob 36 is tilted in the direction of arrow I.

As a result, in FIG.
4 are fixed contacts 48 and 5 as shown by dotted lines, respectively.
It will come into contact with 2.

At this time, the motor 20 is temporarily reversed, and the control transistor 64 is turned on by applying the reverse starting current to the base, and accordingly, the control transistor 66 is also turned on. As a result, the potential of the comparison voltage detection terminal 6 rises, and the output terminal 3 goes into the Lo state. Therefore, switching transistor 6
2 is turned off, power supply to the motor 20 is stopped, and the motor 20 is also stopped.

Next, when the ashtray section 14 is in the pulled out state and the switch button 24 is pressed to turn it on in the same manner as in the previously described storage state, the motor 20 is reversed and when the ashtray section 14 reaches the storage end, the first The switching knob 36 shown in the figure is tilted in the direction of the arrow, and the power supply to the motor 20 is stopped as described above.

By the way, the inner box 16 of the ashtray section 14
If an excessive amount of cigarette butts accumulates in the ashtray section 14 and gets caught in the ashtray section 14, making it impossible to store it, the motor 2
0 will be overloaded and an overvoltage will be applied to the base of control transistor 64. As a result, the control transistor 64, the control transistor 6
6 are turned on, the potential of the comparison voltage detection terminal 6 of the control IC 60 rises, and the output of the output terminal 3 goes into the Lo state.

As a result, the transistor 62 is turned off, the power supply to the motor 20 is stopped, and the storage drive of the ashtray section 14 is stopped.

As described above, according to the electric ashtray device according to the present embodiment, since there is no need to use sliding contacts as in the conventional case, it is possible to stabilize the drive of the ashtray portion and improve the durability of the device. .

Furthermore, the electric ashtray device according to this embodiment has an overvoltage detection mechanism, and even if an overload is applied to the ashtray section, the motor etc. can be protected by stopping the drive of the ashtray section. .

Furthermore, in this embodiment, a drive/control system including a drive motor 20, a switching knob 36, a control section 54, etc. is integrally formed in the ashtray section 14, thereby making the device more compact.

[Effects of the Invention] As explained above, the electric ashtray device for a vehicle according to the present invention includes an end detection section that mechanically detects the end of the drawer/retraction of the ashtray section, and a control that controls the drive of the drive section. Since the apparatus is equipped with a part and a part, it is possible to achieve smooth operation and improved durability of the apparatus.
