Abstract

PURPOSE:To prevent production of uncomfortable sensation due to hot air when a driver rides on a car, by a method wherein an indoor temperature sensor, a dew condensation sensor, and an outer key switch and the like are provided, and by means of signals therefrom, opening and closing of a sun roof and a window glass are automatically controlled. CONSTITUTION:During parking in a summer season, when temperature in a car room is increased owing to a solar heat and exceeds a set value, an indoor temperature sensor 7 is turned ON. If it is not during rainfall, a dew condensation sensor 6 is also turned ON. In this case, when a driver unlocks the outer key of a door in order for riding, an outer key switch 5 is turned ON. As a result, since an automatic release circuit is closed and motors 1 and 3 are both forward run, a sun roof and a window glass are respectively released. When the sun roof and the window glass are respectively brought into a full opening state, limit switched 8 and 9 are brought into an OFF-state and the motors 1 and 3 are stopped. This constitution enables hot air in a car room to be exhausted to the outside before the driver rides on.

Description

[Detailed description of the invention] Industrial applications The present invention relates to an automobile window opening/closing device.

Conventional technology Automated computer windows have side windows that are opened and closed by window glass installed in the door, and roof windows that are opened and closed by a sunroof.Both the door window glass and the sunroof are operated by a power window motor and a sunroof motor. Each can be electrically controlled to open and close.

Generally, when a car is parked, all the windows are sealed, so if the car is parked for a long time in the summer, the interior of the car will become extremely hot, so if you get into the car in that condition, first insert the ignition key. After turning on the ignition switch, operate the door window glass opening/closing switch (power window switch) to fully open the door window glass, and operate the sunroof opening/closing switch to fully open the sunroof and allow outside air to circulate. Normally, the hot air inside the cabin is released to the outside, but in reality, the heat from the time you get into the extremely hot cabin until you open all the windows is extremely high, causing serious damage to the occupants. It gives a feeling of discomfort.

In order to solve this problem, in addition to the two positions for locking and unlocking, the key cylinder of the door has a third operating position.When getting into the car, insert the key into the key cylinder and turn it to the unlock position to open the door. When the driver unlocks the vehicle, the key is turned further to the third operating position, which activates the switch, rotates the sunroof motor, and opens the sunroof, allowing the sunroof to be opened before entering the vehicle. A device has been developed and published in Japanese Patent Publication No. 58-23249.

Problems to be Solved by the Invention In the case where the door key cylinder is provided with two positions for locking and unlocking as well as a third operation position for opening the sunroof as described above, the door key cylinder is extremely special. Not only does it have an economical problem in that it is quite expensive due to its structure, but the sunroof is opened by the driver who is about to get into the vehicle, which can cause the interior of the vehicle to become abnormally hot. Sometimes people get in the car by just unlocking the door without realizing that someone is there, or conversely, when they turn the key with the intention of only unlocking the door without needing to open the sunroof, they accidentally turn it too much and the sunroof opens. However, it has the problem that it is not very convenient to use even though it is quite expensive as mentioned above.

The main purpose of the present invention is to solve the problems of the conventional device as described above.

Means for Solving the Problems The present invention is equipped with a sunroof whose opening/closing is controlled by a sunroof motor and a window glass whose opening/closing is controlled by a power window motor. In a vehicle equipped with a sunroof and window glass opening/closing operation circuit that opens and closes the sunroof and window glass by rotating a power window motor, the sunroof and window glass opening/closing operation circuit has a check that the temperature inside the vehicle is above the set value. An indoor temperature sensor that activates when it detects whether it is raining, a dew sensor that activates when it detects whether it is raining, and an outer key switch that activates when it detects whether the outer door key is locked or unlocked. and a switching relay that operates by detecting whether the ignition switch is on or off, and when the ignition switch is off, the vehicle interior temperature is above the set value of the interior temperature sensor, and it is not raining, the door outer key is activated. The vehicle is characterized by the addition of an automatic sunroof and window opening circuit that automatically rotates the sunroof motor and power window motor in the direction of opening the sunroof and window glass when the vehicle is unlocked.

As a result of the above, when the driver attempts to get into the vehicle in the summer when the interior of the vehicle is abnormally hot and the driver unlocks the outer key of the door, the automatic opening circuit closes and the sunroof and windows open unless it is raining. All the windows were fully opened, and the hot air inside the vehicle leaked out before the driver got into the vehicle.
To significantly reduce the driver's discomfort when getting into the vehicle.

When you turn on the ignition switch after getting into the car as described above, the switching relay switches from the automatic opening circuit side to the opening/closing operation circuit side, and the sunroof and window glass can be opened and closed by operating the sunroof opening/closing operation switch and window opening/closing operation switch. Each of them becomes a controllable state yE.
