Description

[Detailed explanation of the idea] The present invention relates to improvements in vehicle doors.

BACKGROUND ART Conventionally, in order to prevent fogging from adhering to the windshield of a vehicle, an anti-fog device has been put into practical use that is connected to a blower and blows hot or cold air from below the windshield toward the windshield. Additionally, in order to prevent door glass from fogging, devices that are connected to an air blower and blow hot air toward the glass are in practical use. However, providing air ducts from the heater to the glass of both doors has disadvantages in terms of space and cost.

The present invention was devised in view of the above, and consists of a through-hole drilled at a position recessed into the vehicle interior from the outer surface of the door outer panel below the window glass, and a through-hole installed in the through-hole to provide visibility to the side of the vehicle interior. One end is opened in the vicinity of the transparent plate on the inner surface side of the door inner panel to generate an air flow along the inner surface of the transparent plate, and the other end is opened in the vicinity of the transparent plate on the inner side of the door inner panel, and the other end is opened in the vicinity of the transparent plate on the inner surface side of the door inner panel. An air passage is provided in a portion of the plate that is located in front of the vehicle and is recessed from the outer surface of the door outer panel and that is exposed to negative pressure when the vehicle is running, and that air is opened toward the front of the vehicle in the front pillar adjacent to the door. An intake duct is provided, an intermediate duct is provided at the front end of the door so as to be in close contact with or close to the rear end of the air intake duct when the door is closed, and an exhaust duct is provided at the other end opening. The object of the present invention is to provide a vehicle door characterized in that the vehicle door is configured such that the traveling wind that has flowed into the intermediate duct from the air intake duct is blown out toward the exhaust duct.

According to the present invention, the negative pressure generated when the vehicle is running causes the air inside the vehicle interior to be discharged from the vicinity of the transparent plate to the outside through the air passage, and at this time, the air inside the vehicle interior is discharged from the inner surface of the transparent plate. The air flow along the air passage prevents the inner surface of the transparent plate from fogging up, and the air flow discharged from the opening at the other end of the air passage prevents dust and water droplets from adhering to the transparent plate. It has the effect of ensuring good visibility of the transparent plate on the vehicle side.

However, according to the present invention, there is no need to provide a long air duct from the air blower, so it is very advantageous in terms of space and cost. Furthermore, the anti-fogging effect can be further improved by using the conventional air blowing device in conjunction with an anti-fogging device, or by appropriately setting the air flow within the vehicle interior.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

In the embodiment shown in FIGS. 1 to 3, the reference numeral 2 generally indicates the cab of the truck;
4 is a door whose front end is pivoted to the front pillar 6. The door 4 is composed of a door outer panel 8 and an inner panel 10, has a window glass 12, and further has a communication hole 14 formed in its lower part to communicate the inside and outside of the vehicle interior. In order to close the communication hole 14, a transparent plate 20 made of glass, plastic, etc. (of course, a transparent lens may also be used) is attached via a weather strip 18, which is a sealing means known per se. An air intake port 22 is formed in a portion of the inner panel 10 near the transparent plate 20 (preferably near the rear end of the transparent plate 20 as shown), and an air outlet 24 is formed in the front portion of the outer panel 8. The structure is such that air entering from the outer panel 8 and the inner panel 10 can exit from the outlet 24 through a passage formed by the outer panel 8 and the inner panel 10. Further, the front pillar 6 is provided with an air intake duct 30 that opens toward the front of the vehicle, and the front end of the door 4 is provided with an intermediate duct 32 that is closely or close to the rear end of the air intake duct 30 when the door is closed. It is being Furthermore, a discharge duct 34 is attached to the discharge port 24. The diameter of the front end of this discharge duct 34 is formed to be larger than that of the rear end of the intermediate duct 32, so that air is blown out from the intermediate duct 32 toward the discharge duct 34.

Since this embodiment has the above configuration, when the vehicle is running, air enters from the air intake duct 30, air is blown out from the intermediate duct 32 toward the exhaust duct 34, and at the same time the outer panel 8 and the inner panel 10
The air in the passage formed by the exhaust duct 3
4, and the air inside the vehicle compartment is also sucked into the passage from the intake port 22. At this time, the air inside the vehicle compartment flows along the inner surface of the transparent plate 20 as shown by the arrow 28, and Since clouding of the transparent plate 20 is prevented and air is vigorously discharged from the discharge duct 34, dust, water droplets, etc. adhering to the outer surface of the transparent plate 20 can be effectively removed.

As described above, according to this embodiment, there is no need to provide a long air duct from the air blower (not shown), so it is not only very advantageous in terms of space and cost, but also improves the visibility of the transparent plate toward the vehicle side. It has the action and effect that can be ensured. In addition, by using a conventional anti-fog device using air blower, or by appropriately setting the air flow inside the vehicle, for example, the arrow 38
If airflow is provided as shown in the figure, the anti-fogging effect will be even better.

As shown in FIG. 4, the air intake duct 30 and the intermediate duct 32 are made of a flexible joint 3 made of an elastic material such as rubber.
6, the air intake duct 30
The air flowing into the intermediate duct 32 can be prevented from leaking to the outside, and the effect of removing water droplets and the like can be increased accordingly.
