[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle interior ventilation device for an automobile.

[0002]

[Prior Art]

 A vehicle body is provided with a vehicle interior ventilation device for exhausting outside air and the like introduced from an outside air introduction hole provided in the front of the vehicle compartment to the outside of the vehicle compartment.

FIG. 10 and FIG. 11 show a vehicle interior ventilation device 3 provided on a vehicle body panel 2 inside the bumper 1. The vehicle interior ventilation device 3 is composed of a ventilator outlet 5 having an opening window 4 as shown in FIG. 12, and a thin film valve main body 6 provided in the ventilator outlet 5.

The vehicle interior ventilation device 3 opens the valve body 6 to the outside by the air pressure in the vehicle compartment 7 to open the opening window 4, and exhausts the air in the vehicle compartment 7 to the outside of the vehicle compartment 7.

[0005]

[Problems to be solved by the device]

 However, when the air volume from the passenger compartment 7 increases momentarily, the valve body 6 may open too much and stick to the back surface of the bumper 1 to open the opening window 4. At this time, when the pressure inside the vehicle compartment 7 becomes negative with respect to the outside of the vehicle compartment 7, the outside air flows back into the vehicle compartment 7. In particular, hot summer air flows in during the summer months, which causes passengers to feel uncomfortable.

An object of the present invention is to solve the above problems and to provide a vehicle interior ventilation device for an automobile, which can prevent the valve body from opening too far and prevent the backflow of outside air.

[0007]

Means for Solving the Problems In order to solve the above problems, the present invention is provided in a vehicle body panel and opens a valve body formed of a thin film by air pressure introduced into the vehicle interior to ventilate the vehicle interior. In a vehicle interior ventilation device for an automobile, a valve stopper for limiting the opening angle of the valve body is provided outside the valve body.

[0008]

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings, in which the same parts as those in FIGS. 11 and 12 are designated by the same reference numerals.

1 to 3, reference numeral 8 denotes a vehicle interior ventilation device mounted on a side body panel 2 inside the bumper 1. As shown in FIGS. 4 to 6, the vehicle interior ventilation device 8 includes a ventilator outlet 12 in which an opening window 11 is formed by partitioning a frame 9 on four sides by a grid-shaped crosspiece 10, and an opening of the ventilator outlet 12. The valve body 13 is made of a resinous thin film and is provided on the outside of the window 11. The valve body 13 is provided on the outside of the valve body 13.

As shown in FIG. 7, the valve body 13 is provided with a pair of projecting pieces 16 each having a cutout hole 15 for suspension provided on the upper side, and the cutout hole 15 is provided on the rear surface of the ventilator outlet 12. The protrusion 17 is engaged and suspended. On the other hand, the valve stopper 14 is composed of a tongue-shaped seat 18 as shown in FIGS. 8 and 9, and is provided with a large number of projections 19 on the back surface of the valve body 13 side. The valve stopper 14 is provided at its upper end with a pair of arms 20 which are bent outwards from each other, and the arms 20 are engaged with the protrusions 17 and are suspended together with the valve body 13.

According to the above configuration, the air introduced into the vehicle compartment 7 causes the valve body 13 of the vehicle interior ventilation device 8 to rotate and open the opening window 11. At this time, the valve stopper 14 rotates together with the valve body 13 to limit the opening angle of the valve body 13. Since the valve stopper 14 is provided with a large number of protrusions 19 on its back surface, the contact area with the valve body 13 is small and the valve body 13 does not stick to the valve stopper 14.

[0012]

[Effect of the device]

 As described above, according to the vehicle interior ventilation device of the present invention, since the valve stopper that restricts the opening angle of the valve body is provided outside the valve body formed of the thin film, the valve body opens too much. It is possible to prevent problems such as sticking to the outer bumper or panel. Also, since the opening angle of the valve body is limited, there is no need to consider the shape of the body side or the distance of the bumper, etc. Therefore, common parts of each specification can be used, and parts management becomes easy.
