JPS601080A - Air discharging construction on opening and closing door - Google Patents

Abstract

PURPOSE:To eliminate uncomfortableness due to the difference in pressure on closing a door without affecting the air conditioning efficiency by providing a cap which is interlocked with the opening and closing of said door, on an air discharging hole. CONSTITUTION:When a door 8 is operated for closing, a cap 9 is not operated until a lower edge part 20 is brought in contact with a link arm 16, leaving an air discharging hole 6 open. Thereby, the compressed air in a car room 4 caused by the closing action of the door 8 is securely discharged through the air discharging hole 6 out of the car room 5. Accordingly, uncomfortableness due to the rise in car room pressure on closing the door 8, hardness in closing the door 8, etc. can be solved. And, when the lower edge part 20 is brought in contact with the link arm 16 and the door 8 is closed, the link arm 16 is rotated in the direction opposite to the direction in which a spring 19 is energizing, causing the cap 9 to operate in the closing direction through a link rod 18 and a link arm 12, and closing the air discharging hole 6. And the air conditioning efficiency of an air conditioning unit is not affected as the result of this.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air bleed structure for opening and closing a door, and more particularly to an air bleed structure for opening and closing a door, which suppresses an increase in air pressure in a vehicle interior when the door of an automobile is closed.

In general, when opening and closing the doors of a car, especially when closing the doors, if the interior of the vehicle is sealed, the closing operation of the door compresses the air inside the vehicle and increases the pressure, causing injury to the occupants. Not only does it give you a pleasant feeling, but it also increases the indoor pressure, making it easier to intercrop f! A compressive reaction force is applied to the door b-f', making it difficult to close the door. By the way, a car has a ventilation opening in the car body that communicates the inside and outside of the car, and the air inside the car can be vented to the outside of the car through this opening. The opening is left open because the process is performed using the difference in outside air pressure.

Therefore, when the pressure inside the vehicle increases when the door is closed, the air inside the vehicle is exhausted from the opening. Conventionally, this ventilation opening is used to bleed air when the door is closed. It had a structure.

However, in the conventional air bleed structure for opening and closing doors using ventilation openings, although it is possible to bleed air from the vehicle interior through the ventilation openings when the door is closed, Since the opening mentioned above was only intended for ventilation inside the vehicle, the opening area was not made too large in relation to the air conditioning efficiency of the vehicle interior by the air-button device, and the amount of air bleed when the door was closed was also reduced. As a result, it is not sufficient to eliminate the discomfort caused when the door is closed and the compression reaction force against the door.In order to definitely eliminate this, an attempt was made to widen the opening area of the ventilation opening. This poses a problem in that cold and warm air for air conditioning from the air conditioner leaks through the opening, reducing air conditioning efficiency and making it easier for dust to enter.

This invention was made by focusing on these conventional problems, and eliminates the discomfort caused by pressure changes when the door is closed.
The purpose of the present invention is to provide an air bleed structure for opening and closing the door, which allows the door to be easily closed and does not affect air conditioning efficiency.

Specifically, in the air bleed structure for opening and closing the door of the present invention, an air bleed hole is provided in the vehicle body to communicate the inside and outside of the vehicle, and an air bleed hole is provided in the air bleed hole in conjunction with the opening and closing of the door. By providing a lid that opens at least when the door is closed (here, the operating state from the open state to the fully closed state; the same applies hereinafter) and closes temporarily when the door is closed. , which solves the above conventional problems.

The present invention will be explained below based on the drawings.

1 to 3 are diagrams showing a first embodiment of the present invention. In the figure, reference numeral 1 denotes an automobile, and a floor panel 3 constituting a body 2 of the automobile 10 is provided with an air vent hole 6 that communicates an interior 4 of the vehicle and an exterior 5 of a single cabin. This air vent hole 6 is formed in the floor panel 3 at a corresponding portion below the seat (not shown).
In addition to preventing direct exposure to the side of the vehicle interior 4, a net 7 is placed on the floor nozzle 3 at a location corresponding to the air vent hole 6.
is set to prevent the luggage in the vehicle interior 4 from falling through the air vent hole 6. The air vent hole 6 is provided with a lid 9 that opens and closes the air vent hole 6 in conjunction with the opening and closing of the door 8. This lid 9 is rotatably provided on the lower surface side of the floor panel 3 and can be linked with the opening and closing of the door 8 via a link mechanism 10. The link mechanism 10 includes a link arm 12 integrally provided on the rotation shaft 11 of the lid 90, a link arm 16 rotatably attached to a plug 15 provided on the outer panel 14 of the side sill 13,
Outer panel 14 and inner panel 1 of side sill 13
The link rod 18 passes through the page 7 and connects the link arms 12 and 16.

Further, the link arm 16 on the side sill 13 side is biased in the direction of the arrow in FIG. 3 by a spring 19, and biases M9 in the opening direction via the link rod 1B and the link arm 12. When the door 3 is closed, the lower edge 20 of the door 3
comes into contact with the link arm 16, the link arm 1
6 is rotated in the opposite direction to the arrow in FIG. 3 to open the lid 9.
is now closed.

Therefore, when the door 8 is opened, the lower edge 2 of the door 8 is
Since the link arm 16 is not in contact with the link arm 16, the link arm 16 is rotated in the direction of the arrow A in FIG. It is positioned through the link rod 18 and link arm 12 with the air vent hole 6 open. In this case, since the air vent hole 6 is provided with the net 7, the luggage in the vehicle interior 4 will not fall from the air vent hole 6. Next, when the door 8 is operated to close once from the above state, the lid 9 does not operate until the lower edge 2o of the door 8 comes into contact with the link arm 16, leaving the air vent hole 6 open. Therefore, when the door 8 closes, the compressed air in the vehicle interior 4 is reliably discharged from the air vent hole 6 to the exterior of the vehicle 5, which may cause discomfort or difficulty in closing due to the pressure increase in the single interior when the door 8 is closed. will be cancelled. Then, when the lower edge 20 of the door 8 comes into contact with the link arm 16 and the door 8 enters the "closed state", the link arm 16 moves to the spring 19.
rotates in the opposite direction to the biasing direction (arrow 1 A direction in Figure 3),
The lid 9 is operated in the closing direction via the link rod 18 and the link arm 12 to close the air vent hole 6. As a result, when the door 8 is closed, the air in the vehicle interior 4 will not leak through the air vent hole 6, and the air conditioning efficiency of the air conditioner will not be affected.
