ることを目的としている。(Industrial field of application) The present invention relates to a power window device used for automatically opening and closing an automobile window glass by a motor,
Particularly, it relates to a power window device having a one-touch mechanism. (Prior Art) Conventionally, as a power window device as described above,
There was something like that shown in the figure. In the illustrated power window device 100, reference numeral 101 is a power source, reference numeral 102 is an ignition switch, reference numeral 103 is a power window switch including a movable contact 103a, manual operation fixed contacts 103b and 103c, and one-touch operation fixed contacts 103d and 103e. Reference numeral 104 is a power window motor connected to a window glass (not shown), reference numeral 105 is a control unit, and an exciting coil 105c for individually driving relay contacts 105a and 105b for switching the current of the power source supplied to the power window motor 104. , 105d, an IC 105e, and a rotation detection transformer 105f for the power window motor 104. In such a power window device 100, when the movable contact 103a is connected to the manual operation fixed contact 103b by turning on the power window switch 103 while the ignition switch 102 is on, the current from the + B power source is controlled by the control unit 5. Input to the ground through the exciting coil 105c, the manual operation fixed contact 103b, and the movable contact 103a, and the exciting coil 105c is excited, so that the relay contact 105a is switched to the lower side in the figure. By this, + B
The current of the power supply is input from the terminal of the control unit 5, and the relay contact
105b, the terminal of the control unit 5, the power window motor 104, the terminal of the control unit 5, the relay contact 105a, the transformer 105f to the ground to flow, the power window motor 104 rotates forward, the operation time of the power window switch 103 Corresponding to, the window glass (not shown) is operated to the open side. In addition, when the ignition switch 102 is on, the movable contact 103a is turned on by turning on the power window switch 103.
When contacting the fixed contact for manual operation 103b and the fixed contact for one-touch operation 103d, the current from the + B power source flows to the ground via the exciting coil 105c, the fixed contact for manual operation 103b, and the movable contact 103a, and the exciting coil 105c Is excited, the relay contact 105a is switched downward in the figure. As a result, the current from the + B power source is input from the terminal of the control unit 5, and the relay contact 105b, the terminal of the control unit 5, the power window motor 104, the terminal of the control unit 5, the relay contact 105a,
It flows to the ground through the transformer 105f, the power window motor 104 rotates in the forward direction, and the window glass is operated to the open side. When the power window motor 104 rotates forward, the transformer 105
A slight voltage fluctuation occurs in a part of the coil of f, and the voltage fluctuation is input to the IC105e and the IC105e turns on, and is output to the ground via the terminal of the control unit 5, the one-touch operation fixed contact 103d, and the movable contact 103a. It When the window glass reaches the fully open position or the fully closed position and is forcibly stopped, the ripple generated by the power window motor 104 disappears and the IC 105e turns off at the same time.
The excitation of the exciting coil 105a is stopped, the relay contact 105b is restored, the current supply to the power window motor 104 is cut off, and the power window motor 104 is stopped. (Problems to be solved by the invention) However, in the power window device as described above, when the power supply current is supplied to the power window motor 104, the current is supplied through any one of the relay contacts 105a and 105b. If the supply voltage is high, an arc may occur between the contacts when each contact switches from the contact state to the separated state.If the generated arc is large, the contacts burn out and become conductive. There is a problem that it may cause malfunction due to defects. Therefore, in order to solve such problems, it was considered to use a relay with a large air gap between contacts or to separately connect a capacitor for contact protection, but in both cases, the relay becomes larger. It was difficult to be compact and lacked reality. (Purpose of Invention) The power window device according to the present invention has been made in view of the above-mentioned problems, and even if the device has a high rated voltage,
It is an object of the present invention to provide a power window device that has a compact outer shape with less arcs generated between relay contacts.
