Description

Automatic Window Opening and Closing Device Using Time Switch Combined with Shape Memory Alloy {omitted}

The present invention relates to a window automatic opening and closing device according to the change in the indoor temperature of the vehicle and a method of constructing the same, to prevent explosion safety accidents caused by excessively high indoor temperature of the car parked in the sunlight in summer, destruction of electronic components, damage to the portable device The present invention relates to a method of auto-opening and closing a window of a vehicle.

Cars parked with the doors and windows closed under the sun in summertime can quickly reach room temperatures as high as 90 ° C.

Therefore, an increase in the room temperature of the vehicle may cause discomfort, and there is an inconvenience of explosion of a flammable material such as a disposable lighter, destruction of electronic parts, and melting of portable goods.

In order to alleviate this inconvenience, various methods and devices are known or developed. However, by using the shape memory alloy to open or close the windows mechanically, or install a sunroof or vent, the design, high cost, and excessive power consumption due to the shape change of the vehicle were raised as disadvantages, and the practical use was sluggish. There was no device using memory alloys and time switches.

The present invention has been invented to solve the above problems, the indoor temperature of the high temperature is automatically discharged to the outside when the car parked for a long time without the driver in the summer sun, the indoor temperature is not too high, the production cost is It is an object of the present invention to provide an apparatus and a method of configuring the same, which are inexpensive and can minimize battery power consumption.

There is no problem with the air conditioner when the driver is in the car. However, when the car is parked in the summer sun and there is no driver, the indoor air with high temperature should be discharged automatically. Using an electric temperature sensor or exhaust motor causes a large amount of battery power to be consumed in a short period of time. To minimize battery power consumption, do not use an electric temperature sensor or exhaust motor, but operate the window opening / closing motor (collectively referred to as window opening motor and window closing motor) (30) for a short time to solve the problem by opening or closing the window slightly. It is.

Therefore, the shape memory alloy does not require power, and it bends when the temperature is above the reference temperature, so the time switch is turned on so that the power opens the window slightly so that the indoor air of high temperature is naturally ventilated. After the time, the time switch is turned OFF. If the temperature falls below the reference temperature, another time switch is turned on to operate the window closing motor to close the window.

The power consumption is only one hour of operation because the window opening motor operates once during the day when the room temperature increases due to continuous sunlight, and the window closing motor operates once in the evening when the room temperature decreases due to the sun disappearing. To consume. In addition, since there is no driver, it is directly connected to the power supply of the battery regardless of the use of the ignition key of the car, and provides a method and a manufacturing method connected in parallel with the existing window opening and closing switch.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary view of a conventional window opening and closing circuit.

2 is an exemplary view of the present invention. The shape memory alloy 10 is a conventional shape memory alloy which can be changed in shape according to temperature change. The shape memory alloy 10 may be any shape and shape such as a curved shape, a spring shape, a rod shape, and the time switch A 21 and the time switch B 22. It is possible if a switch can be applied or mechanical pressure can be applied.

The reference temperature of the shape memory alloy is 45 ° C, but it can be manufactured by setting the range of 30 ° to 90 ° according to the type of vehicle.

The window opening motor 31 and the window closing motor 32 are existing window opening and closing motors 30 or sunroof opening and closing motors that are currently used in automobiles, and may be made of one motor integrating the opening and closing functions. .

The time switch A 21 and the time switch B 22 may be either electronic or mechanical, and any time switch currently available or commercially available may be used. The time setting is suitable for 2 seconds, but it can be set at the time of manufacture within 0.1 second to 60 seconds depending on the type of car.

The + terminal of the battery power supply 3 may be connected to the lower end of the electrically conductive shape memory alloy 10 as in the circuit of FIG. 2, or alternatively, the time switch A 21 and the time switch B 22 may be connected. ) And the shape memory alloy can only be made to push (press the time switch).

An example of FIG. 2 can achieve the object with the present invention as shown in FIG. 1, but since the shape memory alloy 10 is one, the reference temperature is one. Therefore, the window opening motor 31 and the window closing motor 32 may be repeatedly operated several times a day while the room temperature is repeatedly exceeding or lowering the reference temperature.

Exemplary Figure 2 of Figure 3 is an exemplary diagram that can further save power than Figure 2 because it sets the two reference temperatures of high temperature and low temperature.

Figure 3 is composed of the shape memory alloy 10 of Figure (2) consisting of a high temperature mold storage alloy 11 and a low temperature mold storage alloy (12) operates only once each day, so the advantage of using only minimal power have.

For example,

1. Production

(A) Set the shape memory temperature of the high temperature shape memory alloy 11 to 45 ° C. in order to produce the example 2 of FIG. 3 and bend the straight line at 45 ° C. or lower and the time switch A 21 at 45 ° C. or higher. It was configured to lose.

B) The reference temperature of the low temperature mold retaining alloy 12 was set to 40 deg. C so as to be bent toward the time switch B 22 above 40 deg.

C) Time switch A 21 was set to 1 second, and time switch B 22 was set to 3 seconds.

2. Works

A) The car with the above device was parked in the summer under the sun. When the room temperature rises in the morning and the temperature rises above 45 ° C, the linear high temperature storage alloy 11 is bent and the time switch A 21 is turned on. Thus, the window opening motor 31 is operated for 1 second to open the window 5 cm. Opening time switch A (21) is off, so the window was kept open for 5 cm.

B) When the sunlight becomes weak in the evening and the room temperature decreases to 40 ° C. or lower, the linear low-temperature storage alloy 12 is bent and the time switch B 22 is turned on to operate the window closing motor 32 for 3 seconds. Since the window was closed and the time switch 22 was turned off, the window was closed.

C) The next morning, when the car is again in sunlight and exceeds 45 ° C, the above operation "A" is repeated.

3. Results

When the car's room temperature exceeds 45 ℃, the window opens 5cm, so the heated air circulates with the outside air, and when the temperature is below 40 ℃, the window is closed. At this time, the power used for one day is the power that operated the motor for 4 seconds.

Referring to the effects of the present invention configured as described above are as follows.

Previously, when the indoor temperature of a car standing in the summer sunlight increased, there were inconveniences such as explosion of indoor pollutants, destruction of electronic parts, and damage to portable products. However, if the indoor temperature is increased by parking the car for a long time under the sunlight in the summer by using the present invention, the time switch is turned on by the shape memory alloy to operate the window opening motor to open the window a little and ventilate the indoor air and turn off the evening. When the sunlight becomes weak, the time switch is turned on by the shape memory alloy, and the window closing motor is operated to keep the window locked and off.

Therefore, the present invention is simple and inexpensive, and operates twice a day for about 2 seconds, thereby reducing the power consumption of the battery used, and preventing explosion accidents of automobiles, destruction of electronic components, and damage to portable products. There was.
