The present invention relates to a car ventilator, and more particularly to a car ventilator that can be more quickly ventilated indoor air contaminated by the harmony of the external flow during driving.

By maintaining the comfortable environment by controlling the temperature, humidity and clean air of the vehicle interior, a ventilation device is required to provide a more comfortable environment for the passengers to operate safely.

The ventilation port of such a ventilation device is very important in a vehicle, and it is preferable that the internal air inlet is installed at the position where the negative air pressure is applied to the position where the positive pressure acts, respectively.

However, it is insufficient to ventilate the polluted air (for example, cigarette smoke and dust) in the vehicle interior with only such a vent, so a ventilation apparatus capable of forcibly ventilating to preserve a more comfortable environment is required.

Accordingly, the sun roof that is selectively used has been practically used.

The sunroof is closely attached to the roof of the vehicle so that the sunroof can be opened or closed automatically or semi-automatically to realize various purposes such as ventilation of contaminated air in the room or control of temperature and humidity in the room. Or moisture can be infiltrated, there is a problem that corrosion occurs.

In addition, since the external flow is not harmonized due to the air separation phenomenon due to the flow of air when the sunroof is opened, noise is generated, as well as various problems of reducing the driving force by increasing air drag.

The present invention is devised to solve the conventional problems as described above, an object of the present invention to more quickly ventilate the indoor air contaminated by the harmony of the external flow during driving to preserve the pleasant environment as well as to maintain the air drag It is to provide a vehicle ventilation apparatus that can be reduced.

In order to realize the object as described above, the present invention is to cut a portion of the back glass of the car to form a hole, and in the rear of the hole provided with an opening and closing plate to open and close the opening, the opening and closing of the car, The plate is formed to have a size that can accommodate the whole in the outer portion of the hole, the upper side is hinged fixed, the packing for airtightness is attached to the edge of the inner surface, the rotary lever connected to the inner side of the middle of the opening and closing plate is a vertical portion and It is made to hold a horizontal portion, the upper hinge protrusion of the vertical portion is fixed to the opening and closing plate as a fixing member, a plurality of grooves are formed in one side wall in the horizontal portion made of a hollow member, it is possible to slide back and forth on the horizontal portion of the rotary lever To be coupled to the support member is characterized in that a plurality of fire is formed to be correspondingly inserted into the groove to the side To provide ventilation for the car.

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

1 is a view showing a state in which the ventilation device for a vehicle of the present invention is mounted, Figure 2 is an exploded perspective view showing the configuration of the automotive ventilation device of the present invention, Figure 3 is a coupling state diagram, 1 is a car Back light glass is shown.

A rectangular hole 1a is formed in the upper center portion of the backlight glass 1.

The opening and closing plate 4 is formed slightly larger than the rectangular hole 1a and has hinge grooves 2 formed on both sides thereof, and a rubber packing 3 is attached to keep the inner edges tight. It is hinged to the bracket 6 provided in the loop 5 so as to be selectively opened and closed.

The center lower end of the opening and closing plate 4 is coupled to the hinge protrusion 8 of the rotary lever 7 by the fixing member 10 via the packings 9a and 9b.

The rotary lever 7 is composed of a nonwoven portion 11, in which the hinge protrusion 8 is staggered, and a horizontal portion 14 in which several grooves 13 are opposed to the hollow guide groove 12.

The support member 16 in which several balls 15 are opposed to each other is inserted into the guide hole 12 of the horizontal portion 14 so as to be tightly fixed to the several grooves 13 formed in the guide hole 12. It is possible to selectively change the height.

The support 16 is hinged to the adsorption rubber 17 so that the support 16 can be fixed to the outside of the backlight glass (1) when opened.

One side of the horizontal portion 14 is provided with a rubber packing 18 for preventing the breakage of the backlight glass 1 when the opening and closing portion 4 is closed and for tight fixing.

The opening and closing tube 4 is preferably formed of the same material as the backlight glass 1 to protect the view of the rearview mirror (not shown).

In the vehicle ventilation apparatus of the present invention configured as described above, since the external flow of the vehicle is accelerated in the loop 5 portion of the upper portion of the backlight glass 1, when the rotary lever 7 is rotated due to the lower pressure of this portion, The rotation lever 7 is rotated by the hinge projection 8 of the vertical portion 11 to the fixing member 10 as a hinge.

In this state, when the rotary lever 7 is pushed outward and the suction rubber 17 of the support part 16 is pressed on the outer surface of the backlight glass 1 as shown by the dashed-dotted line of FIG. 3, the opening and closing plate 4 is opened. The air inside the contaminated vehicle is quickly ventilated.

The opening degree of the opening and closing plate 4 can be adjusted by stepwise stretching by pressing the support member 16 to the guide hole 12 of the horizontal portion (14).

When the opening / closing plate 4 is increased to a predetermined size in the width direction of the vehicle, it is possible to expect a decrease in air drag since there is an effect of preventing the wake.

4A and 4B are a plan view and a side view showing another embodiment of the vehicle ventilation apparatus of the present invention, and are electrically connected to a battery (not shown) power supply inside the loop 5 to turn on / off an operation switch (not shown). The rotatable rotating plate 20 is fixedly installed by a servo 19 device which is selectively operated.

One side of the lever 21 is coupled to the ball joint with the rotating plate 20, and the other side is hinged to the bracket 22 fixed to the center top of the opening and closing plate 4 to straighten the rotational movement of the rotating plate 20. Since the opening and closing plate 4 can be selectively opened and closed as shown by the dashed-dotted line of FIG. 4B by switching the motion, the effect of the present embodiment is the same.

As described above, the present invention hinge-installs the opening and closing plate 4 in the upper loop of the center of the backlight glass of the vehicle to selectively open and close the air, thereby quickly ventilating the indoor air of the polluted vehicle as well as noise in harmony with the external flow. Of course, there is an advantage that can reduce the air drag.
