Description

[Detailed Description of the Invention] The present invention relates to a ventilation system for an automobile, and relates to a mounting structure for a valve plate that opens and closes a vent.

As shown in FIG. 1, a conventional automobile ventilation system has a valve plate 4 made of a rubber sheet in contact with the outer surface of a valve receiving frame 3 provided inside the vehicle body 1 facing the vent 2 of the vehicle body 1. A pin 6 protruding from the valve receiving frame 3 is inserted into a small hole 5 in the upper part of the valve plate 4, and the pin 6 is heat-stamped to attach the valve plate 4 to the valve receiving frame 3. In such a conventional configuration, when the valve plate 4 opens, the mounting part 7 is fixed to the valve receiving frame 3, so the valve plate 4 opens in a curved manner. There is a drawback that the number of parts decreases, and the labor of heat caulking is also required.

The present invention was made in view of the above problem, and is mounted by fitting a locking piece of a valve plate provided on the outer surface of the valve receiving frame so that it can be opened and closed from below into the mounting plate protruding from one side of the upper part of the valve receiving frame. An engagement hole is formed on the plate part, and the inner wall of the engagement hole on the side where the valve plate opens is tapered downward to form an inclined surface, so that the mounting part of the valve plate can be fixed. The valve plate can be rotated as a whole when opening the valve plate without being fixed, and the valve plate can be easily attached.

Next, the structure of an embodiment of the present invention will be explained with reference to FIGS. 2 to 7 of the accompanying drawings.

Reference numeral 8 denotes a vehicle body, in which a vent 9 communicating with the outside is opened, and an L-shaped duct 10 with one end open facing the vent 9 and the other end opened inside the vehicle body 8 is installed in a frame body inside the vehicle body 8. It is fixed at 11. In the middle of the duct 10 is a valve receiving frame 13 with an opening/closing port 12 opened,
The valve receiving frame 13 is partitioned by a mounting plate portion 14 that protrudes horizontally from the upper end toward the vent 9 side, and a valve plate 15 made of a rubber sheet or the like is attached to the surface of the valve receiving frame 13 on the vent 9 side. being touched.
A locking piece 17 that extends upward with the same thickness and has an engaging hook portion 16 is integrally provided on the valve plate 15 . Further, the locking piece 17 is provided on the mounting plate portion 14.
An engagement hole 18 is formed into which the valve plate 1 of the valve receiving frame 13 is inserted.
5, the width of the engagement hole 18 is equal to or slightly larger than the thickness of the valve plate 15 at the upper end,
The other side surface of the engagement hole 18 on which the valve plate 13 rotates is tapered downward from the upper end to form an inclined surface 19.

Next, the operation of the above embodiment will be explained.

When exhaust air is discharged from inside the vehicle body 8 when a door is opened or closed, the valve plate 15 rotates outward from the valve receiving frame 13 to open the opening/closing port 12. At this time, the valve plate 15
The upper end of the locking piece 17 is not fixed to the mounting plate part 14.
is only supported on the mounting plate part 14,
In addition, since the engagement hole 18 has an inclined surface 19 that tapers downward on the opening direction side of the valve plate 15, it can be easily rotated, and the contact portion of the engagement hook portion 16 with the mounting plate portion 14 can be easily rotated. The entire body rotates as a fulcrum, and the opening/closing port 12 is completely opened. Next, when venting from the outside, the valve plate 15 comes into close contact with the valve receiving frame 13 and closes the opening/closing port 12.

According to the present invention, in a ventilation device in which a valve plate that opens outward is provided on the outer surface of a valve receiving frame so as to be freely openable and closable, a locking piece is integrally protruded upward from the valve plate, and further, a locking piece is integrally protruded from the upper part of the valve receiving frame. A mounting plate portion is protruded from the side, an engagement hole is formed in the mounting plate portion into which the locking piece of the valve plate is inserted and locked onto the mounting plate portion, and the opening direction of the valve plate of the engagement hole is formed. Since the side of the valve plate is tapered downward to form an inclined surface, the locking piece of the valve plate is not fixed to the mounting plate of the valve holder frame, and the opening of the valve plate on one side of the engagement hole is prevented. Since the direction side is an inclined surface that widens downward, the locking piece of the valve plate can rotate even within the engagement hole, and during the opening operation, the entire valve plate floats above the valve receiving frame. The opening surface can be widened. Furthermore, when attaching the valve plate to the valve receiving frame, it is only necessary to insert the locking piece of the valve plate into the engagement hole of the valve receiving frame, so that the installation is easy.
