Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhaust mechanism for vehicle interior ventilation, such as an exhaust mechanism in a ventilator which is a ventilation mechanism for a vehicle interior.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 5, an exhaust mechanism for ventilating a vehicle interior is provided above the rear portion of the vehicle body (arrow A portion) or below the rear portion of the vehicle body (arrow portion B). The exhaust mechanism (the former exhaust mechanism) provided in the arrow A portion is provided inside the outer plate 1 so as to face the opening 1a provided in the outer plate 1 of the vehicle body, as shown in FIGS. Duct 2 and ventilator butterfly valve 3 provided at the outer opening of duct 2
And a ventilator louver 4 that covers the outer opening of the duct 2. Further, the exhaust mechanism (the latter exhaust mechanism) provided in the arrow B portion is shown in FIGS.
As shown in FIG. 3, the duct 5 is formed of a duct 5 provided inside the outer plate 1 so as to face the opening 1b provided in the outer plate 1 of the vehicle body, and a ventilator butterfly valve 6 provided at the outer opening of the duct 5. The outer mouth portion of is configured to be covered by the rear bumper 7.

[0003]

By the way, in these exhaust mechanisms, in the former exhaust mechanism, the size of the ventilator louver 4 is restricted from the viewpoint of the design of the appearance of the vehicle, so that the exhaust of the air in the vehicle interior is restricted. The amount is also regulated, and it is difficult to improve the ventilation performance of the ventilation mechanism in the passenger compartment and the door closing property. Further, in the latter exhaust mechanism, the opening 1b is located in the lower portion of the vehicle body, so that water may enter the vehicle compartment when the vehicle travels across the vehicle. Therefore, an object of the present invention is to eliminate the above-mentioned problems in an exhaust mechanism for vehicle interior ventilation.

[0004]

SUMMARY OF THE INVENTION The present invention provides a tubular fuel inlet shield which is provided inside an outer plate of a vehicle body so as to face the opening and which is exposed by the tip of the fuel inlet pipe. An exhaust mechanism for vehicle interior ventilation provided, and a duct portion that is provided integrally with the fuel inlet shield and has one end opening toward the fuel inlet shield side and the other end opening toward the vehicle interior side,
The ventilator butterfly valve is attached to the other end opening side of the duct portion, and a lid body that covers the opening portion of the fuel inlet shield in a ventilable manner.

[0005]

In the exhaust mechanism having the above structure, the duct portion forming the exhaust hole is integrally provided on the fuel inlet shield, so that the fuel inlet shield is provided as a lid for covering the outer opening of the duct portion. By using the lid that covers the opening, the lid can function as a conventional ventilator louver.Since the lid is large enough, the ventilation function in the passenger compartment is sufficiently maintained. In addition, it does not impair the external appearance of the vehicle body, and because the position of the fuel inlet shield is quite high from below the vehicle body, water does not enter the vehicle interior when the vehicle is crossing. There is no intrusion. Further, in the exhaust mechanism, the conventional duct that constitutes the exhaust hole can be eliminated, and a lid that covers the opening of the fuel inlet shield is used as a ventilator louver that covers the outer opening of the duct. Therefore, the manufacturing cost of the exhaust mechanism can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a part of a vehicle equipped with an exhaust mechanism according to the present invention. The vehicle is an off-road vehicle for leisure use, and the exhaust mechanism has a fuel supply unit (fueling unit 10).
It is formed integrally with. The refueling unit 10 is shown in FIGS.
As shown in FIG. 2, the fuel inlet shield 11 is provided inside the outer plate of the vehicle body, the fuel inlet pipe 12 faces the fuel inlet shield 11, and the fuel inlet lid 13. It is provided so as to face the opening 14 a provided in the unit 14. The fuel inlet shield 11 has a tubular shape, and a duct portion 21 that constitutes the exhaust mechanism 20 is integrally formed.

As shown in FIGS. 3 and 4, the exhaust mechanism 20 includes a duct portion 21 integrally provided on the fuel inlet shield 11 and a ventilator butterfly valve 22.
And a ventilator louver 23.
The duct portion 21 has a tubular shape and extends obliquely upward with respect to the fuel inlet shield 11. In this state, one end of the duct portion 21 is opened to the fuel inlet shield 11, and the other end is opened to the vehicle compartment. The ventilator butterfly valve 22 is rotatably assembled in the inner duct 24, and is fitted to the other end opening side of the duct portion 21 in this state. The ventilator louver 23 is also used as the fuel inlet lid 13, and is attached to the opening of the fuel inlet shield 11 at one end edge portion thereof so as to be rotatable inward and outward, and at the other end edge portion, a locking means. Is locked to the lock pin 15 which constitutes As a result, the ventilator louver 23 covers the outer opening of the fuel inlet shield 11 so as to allow ventilation, and indirectly covers the one end opening of the duct portion 21. When supplying fuel,
The lock pin 15 is pulled by remote control to release the hooked state of the ventilator louver 23, thereby opening the ventilator louver 23 and enabling oil supply.

In the exhaust mechanism 20 having such a structure, the ventilator louver 23 that covers the outer opening of the duct portion 21 by integrally providing the duct portion 21 forming the exhaust hole with the fuel inlet shield 11.
The fuel inlet lid 13 that covers the opening of the fuel inlet shield 11 can also be used as both. Since the fuel inlet lid 13 has a sufficient size, it is possible to sufficiently maintain the ventilation function in the vehicle compartment, without impairing the external appearance of the vehicle body. Due to the height of the installation position, water will not enter the passenger compartment when the vehicle is crossing. Further, in the exhaust mechanism 20, the conventional duct forming the exhaust hole can be eliminated, and the ventilator louver 23 that covers the outer opening of the duct and the fuel inlet that covers the opening of the fuel inlet shield 11 can be omitted. Since the lid 13 is also used as the lid 13, the manufacturing cost of the exhaust mechanism 20 can be reduced.
