Description

Automobile window opening and closing device

The present invention relates to a window opening and closing device for opening and closing a window of a vehicle, and more particularly, to a window opening and closing device using a temperature sensor that is automatically opened and closed by a temperature sensor.

In the summer heat, the gas lighter placed inside the car explodes, and sometimes the fire occurs in the car. This is because the car's windows are parked outdoors with all the windows closed and the air inside the car continues to heat up with the sun's radiant heat to reach dangerous temperatures.

In summer, the temperature inside a car rises to about 70 ~ 80 ℃. Therefore, a material such as a flammable gas lighter may explode and cause a fire in a car. It also happens that a child in a car chokes. Fire or suffocation due to the temperature increase of the car in such a hot weather can be prevented enough by only ventilating the indoor air. However, it is easy for drivers to overlook this, and it is common to keep all windows closed when parking a car for fear of theft. Therefore there is always the possibility of a fire.

Ventilation is required in order to prevent the accident of the cold weather as described above, but the conventional vehicle window opening and closing device has a problem in that it cannot automatically ventilate in structure. Conventional automobile window opening and closing device uses a motor for opening and closing the window, but since the motor is driven by the power of the battery, it does not operate unless the car key is inserted. And even if the car key is inserted and the battery power is applied to the motor, it is impossible to open and close the window automatically when necessary because the window opening and closing must be operated manually.

Accordingly, an object of the present invention is to improve the vehicle window opening and closing apparatus so that the window is automatically opened and ventilated when the indoor temperature of the automobile, in which the window is closed in a cold season, rises to a dangerous temperature.

In order to achieve the above object, the vehicle window opening and closing device according to the present invention includes a window opening and closing motor for opening and closing of a car window, a temperature sensing means for detecting an indoor temperature of an automobile and outputting an electrical signal corresponding to the measured temperature; And a motor control means for determining a current temperature condition of the vehicle interior according to the output of the temperature sensing means, establishing a ventilation plan, and outputting the window opening and closing motor control signal, and driving the window opening and closing motor according to the motor control signal. It characterized in that it comprises a motor drive means.

Hereinafter, the present invention will be described in detail with reference to the embodiment of FIG. 1. The embodiment of Figure 1 is configured to detect the room temperature of the vehicle and the ventilation is performed by opening the window when the room temperature rises above a certain level.

Referring to Figure 1, there is a vehicle battery 10, the positive terminal (+) of the battery 10 is connected to one side of the sensor operation switch 20. The other side of the sensor operation switch 20 is connected to the temperature sensor unit 30, and the negative terminal (-) of the battery 10 is directly connected to the temperature sensor unit 30. Four output terminals # 1 to # 4 of the temperature sensor unit 30 are connected to the motor control unit 40, and the motor control unit 40 is connected to one side of the tact switch unit 60. The other side of the tact switch unit 60 is connected to the motor driving unit 50. Four motors M1 to M4 are connected to the output end of the motor driver 50. On the other hand, there is a remote control unit 70, the remote control unit 70 is connected to the tact switch unit 60.

The battery 10 is configured to supply power to the temperature sensor unit 30 of the next stage, and to supply power to the motor control unit 40, the motor driving unit 50, and the like. In FIG. 1, only the positive terminal and the negative terminal of the battery 10 are connected to the temperature sensor unit 30, but in reality, the battery 10 is configured to supply power to all the electronic devices of the present embodiment. The sensor operation switch 20 is a means for turning on / off that power is supplied from the battery 10 to the temperature sensor unit 30. In the present embodiment, the sensor operation switch 20 is configured to turn on / off the positive side connection of the battery 10 and the temperature sensor unit 30 as shown in FIG. It is also possible to configure to turn on / off.

As described above, in the present embodiment, the indoor temperature of the vehicle is measured by using a temperature sensor, and when the indoor temperature rises above a certain temperature, the window is opened and ventilated by operating a motor that opens and closes the window. By using a temperature sensor, ventilation is automatically performed, which prevents fire due to an increase in room temperature.

When the sensor operation switch 20 is on, the power of the battery 10 is applied to the temperature sensor unit 30 to operate the temperature sensor unit 30.

In this embodiment, the temperature sensor unit 30 is configured to measure the temperature near each window using four temperature sensors. The car's room temperature will vary depending on the location of the sun. In the case of the cold weather, there is a significant temperature difference between the sun and the sun. In this embodiment, by measuring the temperature of the left and right windows attached to the front door of the car and the left and right windows attached to the car rear door, respectively, it was configured to make accurate temperature measurement.

As described above, although the indoor temperature of the vehicle is measured by using four temperature sensors, it is also possible to configure the temperature of the vehicle interior using only one temperature sensor without following this embodiment. The temperature can be measured using one temperature sensor. However, it is difficult to measure the temperature more accurately than when using four temperature sensors. Therefore, there are limitations in establishing a ventilation plan. However, the circuit configuration will be much simpler, so it is better to use only one temperature sensor when considering the cost of the product.

The temperature sensor unit 30 outputs an electrical signal in proportion to the measured temperature. The four temperature sensors output a voltage or current proportional to the measured temperature, and the output voltage or current is input to the next motor control unit 40.

The motor control unit 40 analyzes the temperature previously sensed by the temperature sensor unit 30 to establish the indoor ventilation plan of the vehicle and accordingly outputs a control signal for controlling the window opening and closing motors M1 to M4. The motor control unit 40 operates to ventilate when the set temperature is reached as a result of analyzing the temperature, and operates again to prevent ventilation again when the indoor temperature falls below a certain temperature due to the ventilation.

In this embodiment, the motors M1 to M4 that open and close each of the four windows are configured to be individually controlled. Also configured to control the motor (M1 ~ M4) in pairs. The reason for this configuration is to control the window opening and closing motors M1 to M4 in pairs because the windows on the side where the wind flows in and the windows on the side where the wind flows out must be opened in order for the ventilation to be performed smoothly. And the amount of opening of the window controls the amount of rotation of the motor (M1 ~ M4) to about 3cm. If the amount of rotation of the motor (M1 ~ M4) is too large, the ventilation is good when the window is opened a lot, but there is a risk of theft, and if the amount of rotation of the motor (M1 ~ M4) is too small, the ventilation is poor Therefore, in consideration of this point, the degree of opening of the window and the amount of rotation of the motors M1 to M4 should be determined.

The control signal output from the motor control unit 40 is then input to the motor driving unit 50 via the tact switch unit 60. The tact switch unit 60 is provided in this embodiment to turn on / off the control signal is input to the motor drive unit 50. In the present embodiment, the tact switch unit 60 is configured between the output terminal of the motor control unit 40 and the input terminal of the motor driving unit 50. However, since the tact switch unit 60 is configured for the purpose of turning on / off the driving of the motor, the tact switch unit 60 may be configured regardless of the position without following the present embodiment. That is, the tact switch unit 60 may be configured to turn on / off the power supply of the motor control unit 40, and may be configured to turn on / off the power supply of the motor driving unit 50.

And the tact switch unit 60 is configured a remote control unit 70 to enable remote control. Since the driver is configured to be able to remotely turn on / off the driving of the motor conveniently, this remote control unit 70 is not an essential configuration, and may be configured as necessary.

Next, the motor driving unit 50 is a part for driving the motors M1 to M4 according to the control signal output from the motor control unit 40. This part is directly connected to the motors (M1 ~ M4) and handles a little larger power than the motor control unit 40. Therefore, the part should be designed considering the insulation problem with the motors (M1 ~ M4) and the characteristics of the switching device. do. As the switching element, a power transistor, a MOSFET, or the like can be easily configured. In addition, since many motor drive ICs are commercially available in recent years, the motor drive unit 50 may be driven using a suitable IC.

As the motor driving unit 50 drives the motors M1 to M4, the motors M1 to M4 rotate and the vehicle windows connected to the rotation shafts of the motors M1 to M4 open and close. When the window is opened, the ventilation is performed and the temperature of the vehicle is lowered, thereby preventing the risk of fire due to the temperature increase of the vehicle in the cold.

As described above, the vehicle window opening and closing apparatus according to the present invention measures the vehicle interior temperature by using a temperature sensor and configures the window opening and closing motor to automatically ventilate the indoor air when the measured temperature is higher than the predetermined temperature. In this way, it is possible to prevent the occurrence of a fire due to an increase in the temperature inside the car, which is closed during the summer heat. This car window opening and closing device can be applied to all cars, the driver does not have to worry about the fire.
