[Industrial use]

The present invention relates to a door window glass automatic opening and closing device according to the indoor temperature of the vehicle, and more particularly, to automatically open and close the door window glass when the indoor temperature of the vehicle rises above a predetermined temperature.

[Prior art]

In general, when the car is parked, parking is performed while the door window is closed. At this time, when the car is parked in a sunny place with a lot of sunlight instead of a shade, the interior is completely sealed and the internal temperature is greatly increased.

In order to prevent the room temperature from being raised in this way, it is most preferable to keep the door window glass open.

In view of this point, in the conventional method of opening and closing the door window glass of a car, the user directly opens and closes the door window glass by using a steering wheel or by using a driving motor to open and close the door window glass. Looking at the electrical system of the opening and closing method using a drive motor, the door window glass opening and closing method, also referred to as a power window, as shown in FIG. 4, the ignition switch 101 and the window switch between the battery 100 and the driving motor 103. 202 is electrically connected.

Accordingly, when the door window is to be opened or closed, the drive motor 103 is operated by operating the window switch 102 in which the occupant is disposed at a predetermined position while the ignition switch 101 is turned on. It will be opened and closed by lifting.

[Problem to solve]

However, in the power window device as described above, the window glass must be operated only when the ignition switch is turned on, so that the window glass is opened and closed, so there is no problem in the case of no parking in the parking lot. In most cases, the driver is completely raised the window glass in order to prevent children from coming out to see the business while the door is locked, there is a problem accordingly.

In other words, when parking with the door locked and the window glass fully raised, the indoor temperature rises significantly as described above. Children on board may feel frustrated and severely suffocate. It is often occurring.

Therefore, the present invention is devised to solve the above problems, the object of the present invention is to open the door window glass automatically when the temperature in the car is raised above a predetermined temperature door according to the room temperature rise of the car The present invention provides a window glass automatic opening and closing device.

[Means to solve the problem]

In order to realize this, the present invention provides a power supply of a battery to a temperature sensitive switch having first and second bimetal terminals operated at a predetermined temperature difference from each other through a fuse and a main switch; The first bimetal terminal is connected to a window motor through a relay, and the window motor thereof is connected to a ground wire switch limiting a falling range of the window glass, and the second bimetal terminal is connected to an alarm device through a relay. It provides a window glass automatic opening and closing device according to the rise of the room temperature.

The temperature sensitive switch provides a window glass automatic opening and closing device according to the room temperature increase of the vehicle, characterized in that the first bimetal terminal to operate at 20 to 25 ℃, and the second bimetal terminal to operate at 30 ℃ or more. do.

The ground wire switch has two windows on both sides with a window glass interposed therebetween, and the outer side of the elastic member is formed with a structure in which the case is fixed to the left and right sides of the channel outside the elastic member. It provides a window glass automatic opening and closing device according to the temperature rise.

The ground wire switch provides a window glass automatic opening and closing device according to the increase in the indoor temperature of the vehicle, characterized in that disposed below 140 to 160mm from the top of the channel.

[Action]

According to the above configuration, if the main switch is turned on while the elderly person, such as a child, is in the car during parking, the window glass automatically opens at a predetermined distance when the temperature inside the car rises above 20 ° C. When the temperature rises above 30 ° C., the horn sounds to announce the danger, thus preventing accidents caused by the temperature increase in the car as before.

EXAMPLE

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically realize the above object will be described in more detail.

1 to 3 show a preferred embodiment according to the present invention, the electricity of the battery 1 is connected to the temperature sensitive switch 4 through the fuse 2 and the main switch (3).

The temperature sensitive switch 4 is a switch having two bimetal terminals 41 and 42 which are operated at different temperatures as shown in FIG. 2 (a) and (b). In the present invention, the first bimetal terminal 41 ) Is operated at a lower temperature (about 20 to 25 ℃) than the second bimetallic terminal 42, and the terminal 410 connected thereto is connected to each of the power window driving motors 412 via a relay 411. When the temperature inside the vehicle rises above 20 to 25 ° C. in the on state of the main switch 3, the first bimetal terminal 41 is connected to the contact terminal 410 thereof, and the power of the battery 1 is powered by the power window motor 412. ) To open the window glass.

And the power window motor 412 is installed on the channel 50 for guiding the lifting of the window glass 5 as shown in Figure 3 and the ground wire switch 51 for limiting the falling range of the door glass 5 and The ground wire switch 51 is grounded.

The ground wire switch 51 has two terminals 510 and 511 on both sides with the window glass 5 interposed therebetween, and the elastic members 513 and 514 are supported thereon. Outside the c), the cases 515 and 516 are fixed to the left and right sides of the channel 50.

Accordingly, when the window glass 5 descends and pushes both terminals 510 and 511 to both sides, when the terminals 510 and 511 are spaced apart from each other, the energized power is cut off to stop the lowered window glass 5.

The arrangement position of the ground wire switch 51 configured as described above is determined according to the opening range of the window glass 5. In the present invention, the window glass 5 is disposed 140 to 160 mm from the upper end of the channel 50. ) Open at this same distance.

In the above, the opening degree of the window glass 5 is set to 140 to 160 mm to prevent children in the vehicle from coming out through it when it is opened too much.

The second bimetallic terminal 42 of the temperature sensitive switch 4 is operated at a temperature slightly higher than the first bimetallic terminal 41 (about 30 ° C. or more), and the terminal 420 connected thereto is a relay 421. ) Was connected to the alarm 422 and grounded.

This is very dangerous when the temperature inside the vehicle continues to rise even when the window glass 5 is opened due to the operation of the first bimetallic terminal 41. Therefore, when the temperature inside the vehicle rises above 30 ° C., power is supplied to the alarm 422. An alarm sounded to alert the driver and those around him to the danger.

The device of the present invention is operated regardless of the existing power window device, and the automatic window opening and closing thereof is operated by turning on and off the main switch 3 as necessary.

Therefore, if the main switch (3) is turned on while the elderly, such as children in the car on board, the window glass (5) automatically opens to a predetermined distance when the temperature inside the car rises above 20 ℃, If it rises even higher than this 30 ° C or more, the horn 422 rings to inform the danger, so that an accident due to the temperature increase in the car can be prevented in advance.

[effect]

As described above, according to the present invention, as a simple structure, the door window opens automatically when the temperature inside the car rises above a predetermined temperature during parking, and an alarm sounds when the temperature rises above the bar, due to the increase in the temperature inside the car. It is a useful design that can prevent all accidents in advance.
