[Industrial applications]

 The present invention relates to a vehicle auto window, and more particularly to a vehicle auto window in which a window glass is moved up and down by a window motor connected to a microcomputer.

[0002]

[Problems to be solved by conventional techniques and devices]

 Conventional vehicles are not equipped with the function of opening and closing windows according to the temperature inside the vehicle. For this reason, if the vehicle is parked under the scorching sun in the midsummer with the window closed, the temperature inside the vehicle rises abnormally, and this hot air causes discomfort during riding. Another problem is that if a baby or infant is left in the car and parked under the above conditions, a fatal accident may occur.

The present invention has been made in view of the above problems, and when parking, the window can be automatically opened and closed according to the temperature inside the vehicle, and the temperature inside the vehicle can be adjusted. The purpose is to provide a vehicle auto window that can prevent the occurrence of fatal accidents.

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a vehicle auto window according to the present invention is a vehicle auto window in which a window glass is moved up and down by a window motor connected to a microcomputer. When the temperature sensor detects that the temperature inside the vehicle has risen above a predetermined temperature, the window motor is driven by a command from the micro computer, and the window glass is lowered to a predetermined position. It is characterized by

[0005]

[Action]

 According to the above configuration, the temperature sensor for detecting the vehicle interior temperature is provided, and when the temperature sensor detects that the vehicle interior temperature has risen above the predetermined temperature, the window motor is driven by a command from the microcomputer. In addition, since the window glass is configured to descend to a predetermined position, outside air can be automatically taken into the vehicle, and the temperature inside the vehicle can be adjusted even when the vehicle is away.

【Example】

 An embodiment of a vehicle auto window according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram schematically showing a signal system of a vehicle auto window according to the present embodiment. The microcomputer 14 includes a temperature sensor 11, a raindrop sensor 12, a crime prevention sensor 13, a window motor 15, and an auto. The window sensor 16 and the switch sensor 17 are connected to each other. The temperature sensor 11 detects the temperature inside the vehicle, the raindrop sensor 12 detects whether or not it is raining, and signals from the temperature sensor 11 and the raindrop sensor 12 are sent to the microcomputer 14. As the raindrop sensor 12, a light-receiving element and a light-emitting element (not shown) are arranged on opposite surfaces, and when a raindrop passes between the light-receiving element and the light-emitting element, a pulse signal is output, and the pulse signal causes the raindrop to be emitted. A space-sensing type of sensing is used. In addition, the security sensor 13 detects whether or not a person approaches the vehicle by infrared rays, and the auto window sensor 16 detects whether or not the door is locked by a key. Further, the switch sensor 17 is adapted to detect whether or not the window glass 18 has descended to a predetermined position (for example, about 5 cm from the closed position). The signal is sent to the microcomputer 14. The window glass 18 is operated up and down by the drive of the window motor 15, and the window motor 15 is driven by the microcomputer 14.

The operation of the microcomputer 14 will be described based on the flowchart shown in FIG. First, when the door is locked by the key (step 1), this is detected by the auto window sensor 16, and this detection signal is sent to the microcomputer 14 to enter the auto window mode (step 2). When in the automatic window mode, the microcomputer 14 sends a signal to the temperature sensor 11 to operate the temperature sensor 11 (step 3). Based on the information from the temperature sensor 11, it is judged whether or not the vehicle interior temperature has risen (step 4), and the microcomputer 14 determines in step 4 that the vehicle interior temperature has not risen based on the information from the temperature sensor 11. If not, go to step 8. On the other hand, when it is determined that the temperature inside the vehicle has risen, it is next determined whether or not the window glass 18 is in the closed state based on the information from the switch sensor 17 (step 5). If it is determined in step 5 that the window glass 18 is open, the process proceeds to step 8. On the other hand, when it is determined that the window glass 18 is in the closed state, the microcomputer 14 sends a signal to the window motor 15 to drive the window motor 15 to move the window glass 18 at a predetermined position, for example, 5 cm from the closed state. Lower to the lower position (step 6). At the same time as the window glass 18 descends, the micro computer 14 sends a signal to the raindrop sensor 12 and the security sensor 13 to activate the raindrop sensor 12 and the security sensor 13 (step 7). Next, it is judged whether or not the temperature inside the vehicle has dropped to a predetermined temperature (step 8). When it is determined that the temperature inside the vehicle has dropped to the predetermined temperature, the microcomputer 14 drives the window motor 15 and the window glass 18 To close the window (step 9). At the same time when the window glass 18 is raised, the operations of the raindrop sensor 12 and the security sensor 13 are stopped (step 10), and the process returns to step 4 to perform the same operation as above.

If it is determined in step 8 that the temperature inside the vehicle has not dropped to the predetermined temperature, it is determined whether or not it is raining based on the information from the raindrop sensor 12, and the security sensor 13 determines whether or not it is raining. Based on the information, it is determined whether or not there is a person near the vehicle (step 11). If it is determined that it is raining or that there is a person in the vicinity of the car, the process returns to step 9 to raise the window glass 18 and close the window. In addition, if it is determined in step 11 that it is not raining and there is no person near the vehicle, the process returns to step 4 and the same operation as above is repeated.

As described above, since the temperature sensor 11 is provided in the above-described embodiment, when it is detected that the temperature inside the vehicle is higher than the predetermined temperature, the window glass 18 is automatically lowered to the predetermined position. However, the temperature inside the vehicle is adjusted. Therefore, even if the car is parked in the hot summer sun, the inside of the car will not be covered with abnormal heat, so there will be no discomfort when riding, and further death of babies and infants may occur. Can be prevented.

Further, since the raindrop sensor 12 is provided, it is possible to determine whether or not it is raining, and it is possible to prevent rain from entering the vehicle as the window glass 18 descends. Further, the crime prevention sensor 13 can detect a human figure, and when the human figure is detected, the window glass 18 can be raised to prevent theft.

In the above-mentioned embodiment, the space sensor type raindrop sensor 12 is used, but the raindrop sensor 12 is not limited to this, and any raindrop sensor 12 can be used as long as it can detect whether or not it is raining. ..

[Effect of the device]

 As described above in detail, the vehicle automatic window according to the present invention is provided with the temperature sensor for detecting the vehicle interior temperature, and when the temperature sensor detects that the vehicle interior temperature has risen above the predetermined temperature. Since the window motor is driven by a command from the microcomputer and the window glass is lowered to a predetermined position, outside air can be automatically introduced into the vehicle to raise the temperature inside the vehicle. Can be blocked. Therefore, even if the vehicle is parked under the scorching sun, the inside of the vehicle is not covered with abnormal heat, so that no discomfort is felt when riding and it is possible to prevent the death of babies and infants.
