Abstract

PURPOSE:To enhance the closability of a door to aim at preventing air in the passenger's compartment of an automobile from being excessively vented, by providing such an arrangement that a shut-off valve provided in the edge part of door mounting opening of a vehicle body, for opening and closing a venting port for air in a passenger's compartment, is opened upon opening of a door and closed upon full-closing of the door in accordance with a door opening and closing detection signal. CONSTITUTION:Upon opening of a door 2 a detecting element 12 in a detecting member 10 is projected outward of a vehicle body under the force of a set spring 13, and an actuating rod 16 is moved downward to move a valve element 8 in a shut-off valve 5 in the opening direction thereof in association with the rotation of a bell crank 17. Upon closing of the door the detecting element 12 is retracted so that the bellcrank 17 is swung upward to move the actuating rod 16 so that the shut-off valve 5 is closed. At this time the shut-off valve 5 is gradually closed until the door is fully closed, and is fully closed when the door is fully closed. Accordingly, the venting of air in the passenger's compartment upon closing of the door is continuously carried out, thereby the closeability of the door is not hindered, and the valve is fully closed while the door is fully closed so that it is possible to prevent air from excessively vented.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a vehicle interior air exhaust system for an automobile.

Conventional technology In automobiles, a drafter is usually arranged in the rear pillar or 7 ender, and the negative pressure generated near the outer skin of the car body is used to suck in the air inside the car body to generate furnace air inside the car body. It's Nishide. By the way, even if the drafter is arranged at a specific part of the vehicle body, the exhaust of the cabin air from the drafter cannot keep up with the sudden pressure rise in the cabin when the door is closed, and the door is closed. It has been pointed out that its closed nature is confusing. The ninth way to improve door closing performance is to increase the number of drafters mentioned above, but the reality is that it is not possible to add more drafters unnecessarily as it will spoil the appearance of the vehicle body.

For this reason, for example, as shown in Service Bulletin No. 484, page 288, published by Nissan Motor Co., Ltd. in June 1981, there is a problem in the interior of the vehicle at the edge of the vehicle body opening, which is hidden by the door in the morning when the door is closed. An air exhaust port is formed, and when the door is closed, the air inside the vehicle is also exhausted from this exhaust port, thereby suppressing the rise in pressure within the vehicle interior and improving door closing performance.

This cabin air exhaust port is equipped with a one-way valve made of lightweight, flexible elastic material such as rubber or resin that closes under its own weight, and opens quickly if the pressure inside the cabin increases even slightly when the door is closed. Under normal conditions, the valve closes under its own weight to prevent rainwater, car wash water, dust, etc. from entering through the exhaust port.

Problems to be Solved by the Invention Even if one-way pulp is installed at the air outlet in the vehicle interior, this one-way pulp is lightweight and flexible as described above, and can quickly respond to pressure changes. To open the valve,
When pressure is generated in the parting gap between the door and the edge of the opening of the vehicle body when the vehicle is running, the one-way pulp opens and functions as a drafter, resulting in excessive exhaust, resulting in a problem of lowering cooling and heating performance.

Therefore, the present invention maintains the air outlet in the vehicle interior in an open state when the door is closed, so that the air in the vehicle interior can be smoothly discharged, improving door closing performance, and in addition, when the door is fully closed, the outlet is opened. When it is blocked, air inside the vehicle is sucked in due to negative pressure while driving.
An object of the present invention is to provide an air exhaust device for an automobile cabin that can prevent the air from being discharged, improve door closing performance, and prevent excessive exhaust.

Means for Solving All Problems In the present invention, the cabin air exhaust port is formed in the shape of υ at the edge of the vehicle body opening where the door is attached, and an on-off valve is disposed at the exhaust port to create an FC tank structure. A door opening/closing detection member for detecting opening/closing of the door is disposed at the opening edge of the vehicle body, and the opening/closing valve is fully opened when the door is opened based on the detection action of the door opening/closing detection member, and the door is fully closed. It is equipped with a complete valve train mechanism that closes the on-off valve at certain times.

Does it work when the door is opened? d The opening/closing valve is activated by the detection function of the door opening/closing detection member to open the opening/closing valve, and when the door is closed, the opening/closing valve is kept open until the door is fully closed and the air inside the vehicle is released. The exhaust port is opened, and the air inside the vehicle is discharged from the eM exhaust port when the door is closed, thereby suppressing the rise in pressure within the vehicle interior. When the door is fully closed, the rainbow valve mechanism is actuated by the detection action of the detection member, and the opening/closing valve is closed to close the vehicle interior air outlet, and the vehicle interior air is discharged from the outlet Tc. do.

Example Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In Figs. 1 to 4, numeral 3 denotes a vehicle interior air exhaust port formed at the edge of the vehicle body opening to which the door λ is attached, specifically, at the vehicle body opening edge l on the side where the door lock device (not shown) is installed. The outlet 3 is decorated with a grille.

The valve is an on-off valve arranged on the back side of the grille of the discharge port 3, and is rotatably mounted on a base plate 6 having a valve lower and a bracket 6a protruding from this base plate 6 via a pivot. , the valve lower t and a valve body t that opens and closes, and this valve body r is opened and closed by a valve operating mechanism 7μ, which will be described later.

Reference numeral 10 denotes a door opening/closing detection member for detecting opening/closing of the door λ, and is disposed below the vehicle interior air outlet 3 at the vehicle body opening edge l. This detection member 10 includes a casing l/ fixed to the vehicle body opening edge l with screws, and a casing l//
It consists of a detector/2 which is housed in the IIC and is biased by a set spring 13 and whose tip protrudes outward from the opening edge l of the vehicle body, and when the doorco is fully closed, the detector/2 is It is pushed and applies operating force to the valve mechanism lψ, which will be described later.

lμ is an on-off valve! A valve operating mechanism is attached to the valve body and opens and closes the on-off valve based on the detection action of the detection member IO. 3 is connected to the sales lever /3, and the middle part is pivotally supported by the vehicle body side bracket (1), one end is connected to the lower end of the actuation rod /A, and the other end is connected to the detector 12. It is connected to the rear end of the detector 12.

A bell crank 17 that transmits the entire operating force to the operating rod /A is stretched between the operating rod /A and the on-off valve base plate t, and is pulled upwardly to the valve body If.
Here, the force of the set spring lJ of the door opening/closing detection member 10 is equal to the set spring 1 of the valve mechanism @744.
The spring force is set stronger than 9 force.

According to the structure of the above embodiment, when the door is opened, the detector/co of the detection member io is moved to the outside of the vehicle xb by the force of the set spring 73 as the door is opened. Since the set spring 13 of the shaft valve @ structure H is also set with a strong spring force, the bell crank/7'Ik rotates to pull the operating rod 16 downward, and the opening/closing valve j is turned. Open the valve tt.

When the door is closed, as the door λ closes, the detector/co is pressed by the door controller and moves in the opposite direction to the above-mentioned actuator, so that the valve body r is actuated in the valve-closing direction, but the door λ is not fully closed. The valve will remain open until it reaches its final state, although the degree of vomiting will decrease. Therefore, when the door is closed, the indoor air is discharged from the vehicle interior air outlet 3, suppressing the pressure rise in the vehicle interior and improving the door closing efficiency.When the door λ is completely closed, the detector /2 is pushed to the maximum, causing bell crank /7 to push up Nijisakugai h rod 16 and close valve body r2. The valve-closing property 1c of the valve body 1 is assisted by the set spring 19 of the valve mechanism/4L. Therefore, when the door is fully closed, the closing of the valve body ♂ reliably closes the cabin air outlet 3, so even if negative pressure is generated in the parting gap between the vehicle body opening edge l and the door controller when the vehicle is running. In the above embodiment, the door opening/closing detection member 10 and the valve mechanism lψ are linked by a mechanical linkage. However, in addition to this, there is also a door switch that detects the opening and closing of the door,
It is also possible to fully open and close the on-off valve using an electromagnetic actuator and metal.

Effects of the Invention According to the present invention, when the door is closed, the on-off valve remains open until the door is fully closed. Since the interior air outlet is opened while the door is closed, the exhaust air is discharged from the interior of the vehicle when the door is closed, thereby suppressing the pressure inside the vehicle, thereby improving door closing performance. When the door is fully closed, the detection member closes the on-off valve and opens the discharge port. Since it is reliably closed, the air inside the vehicle will not be exhausted from the outlet due to the 9 pressure during driving, and there will be no excessive exhaust, and therefore, there will be no reduction in the heating and cooling effect, which is a great practical effect. has.
