Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air bleeding device for a vehicle door.

[0002]

[Prior Art]

 In order to prevent dust, water, sound, etc. from entering the vehicle interior from the outside of the vehicle, the vehicle interior of the vehicle is hermetically sealed. However, this makes it difficult for the air in the passenger compartment, which has become high due to the wind pressure of the door when the door is closed, to escape to the outside of the vehicle, making it difficult to close the door. On the other hand, conventionally, a vehicle is provided with a ventilator as a part of a vehicle air conditioner, and when the door is closed, the ventilator bleeds air.

[0003]

[Problems to be solved by the device]

 However, since the above-mentioned ventilator is usually installed in the rear part of the vehicle, it takes time to transmit the air pressure in the passenger compartment when closing the door (particularly the front door), and the air cannot be released quickly. Therefore, there is a feeling of resistance to closing the door.

In view of the above-mentioned conventional problems, an object of the present invention is to provide a vehicle door capable of quickly removing air from the vehicle interior when closing the door and improving the door closing property. To provide an air bleeding device.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a vehicle door with an air bleed duct having an air bleed passage, one end of which is open to the vehicle interior side and the other end of which is open to the vehicle exterior side. The air vent passage of the vent duct is always kept in a closed position to block the air vent passage, and opens and closes the air vent passage when the air pressure inside the cabin becomes higher than the air pressure outside the cabin. Is provided.

[0006]

[Action]

 In the present invention configured as described above, when the door is closed, the on-off valve is opened by the air in the vehicle compartment that is higher than the air pressure outside the vehicle compartment due to the wind pressure of the door, and the air in the vehicle compartment is released from the air vent duct. Get out of the car through the air bleed passage.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 3, a door 10 is provided on a body 20 of a vehicle so as to be rotatable around a hinge (not shown) as indicated by an arrow A in FIG. The door 10 has an outer panel 12 and an inner panel 14, and a front end portion of a bent portion 16 formed by bending a rear end portion of the inner panel 14 at a substantially right angle is joined to the outer panel 12. A trim board 18 is provided on the passenger compartment side of the inner panel 14. The body 20 is provided with a door seal member 22 that seals with the inner panel 14, and a trim board 24 is also provided on the vehicle compartment side of the body 20.

As shown in FIGS. 1 and 3, an air vent duct 30 is provided in the space between the inner panel 14 and the outer panel 12 of the door 10. The air bleeding duct 30 is configured by connecting a first duct 32 and a second duct 34 that communicate with each other. The first duct 32 has an air inlet portion 36 that is open to the vehicle interior side at a portion of the inner panel 14 that is closer to the vehicle interior than the portion corresponding to the door seal member 22, and the second duct 34 is the inner panel. The bent portion 16 of 14 (the outside of the vehicle compartment from the portion corresponding to the door seal member 22) has an air outlet portion 38 that is open to the outside of the vehicle compartment. An air vent passage 40 is formed in the air vent duct 30 from the air inlet portion 36 to the air outlet portion 38. The air outlet portion 38 is provided with a plurality of slanted blades 42, and the trim board 18 is provided with a slit 44 corresponding to the air inlet portion 36.

As shown in FIGS. 1 and 2, a flat plate-like blocking plate 50 is provided in the second air duct so as to close the air vent passage 40. The cutoff plate 50 is slightly inclined so as to be substantially parallel to the opening / closing locus A of the door 10 in FIG. 1 which is a plan sectional view, and also in FIG. 2 which is a vertical sectional view, the air outlet portion is moved downward from above. It is slightly inclined toward the 38 side.

As shown in FIG. 2, the obstruction plate 50 has three oblong air vent holes 52 formed vertically in parallel. An opening / closing valve 54 made of a rubber plate or the like is provided in each air vent hole 52. The open / close valve 54 is connected to the peripheral portion (upper end portion) of the air bleed hole 52 only at the upper end portion thereof, and is normally in a closed position where the air bleed hole 52 is closed by its own weight. It is designed to open the hole 52. Even if air pressure is applied from the outside of the vehicle, the opening / closing valve 54 is blocked by the peripheral portion of the air vent hole 52 and remains in the closed position.

The present embodiment is configured as described above. Therefore, when the door 10 is closed, as shown in FIG. 1, the air inside the vehicle that has become high due to the wind pressure of the door 10 (more accurately, the air inside the vehicle interior than the door 10) enters the air inlet of the air vent duct 30. Attempting to flow from the portion 36 to the air outlet portion 38 through the air vent passage 40, the wind pressure of the air flow causes the on-off valve 54 to open as shown in FIG. Get out of the car through the mouth 38. Therefore, the air in the passenger compartment does not act as a resistance when the door 10 is closed, and the door 10 is smoothly closed.

Further, as shown in FIG. 1, since the blocking plate 50 is slightly inclined so as to be substantially parallel to the opening / closing locus A of the door 10, when the door 10 is closed, the opening / closing valve 54 is moved toward the closing position. Wind pressure and inertial force do not act, and the opening operation of the on-off valve 54 is not hindered.

It should be noted that in FIG. 1, the blocking plate 50 is not limited to being substantially parallel to the opening / closing locus A of the door 10, and may be provided so as to be tilted further clockwise than that. In addition, it goes without saying that the present invention can be implemented in a mode in which various modifications are made based on the knowledge of those skilled in the art.

[0014]

[Effect of the device]

 As described above, according to the present invention, when the door is closed, the air in the passenger compartment quickly escapes to the outside of the vehicle through the air vent passage of the air vent duct, so that the air in the passenger compartment resists the closing of the door. Is reduced, and the closing property of the door is improved.
