DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilating device for a motor vehicle, and more particularly to a ventilating device provided in a pillar portion for preventing a pressure increase in a room when a door is tightened or for performing a ventilation accompanying a ventilation function in a vehicle room. It concerns the device.

[0002]

2. Description of the Related Art As a conventional ventilating apparatus of this kind, as disclosed in Japanese Utility Model Laid-Open Publication No. 2-44511, for example,
A box-shaped duct molded of resin is housed inside the rear pillar, and one of the ventilation holes of this duct is opened to the outside of the vehicle through an outdoor port provided in the outer panel, and the other ventilation port and the vehicle room are connected to the inside of the rear pillar and By connecting via an interior opening provided in the inner panel, ventilation is ensured while preventing the flow of noise and foreign matter.

[0003] However, in the case where the duct, which is not necessarily indispensable from the viewpoint of the body structure, is mounted in the pillar, the weight of the body and the number of assembling steps increase because the number of parts increases. There was a problem.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and enables the use of inner panels and reinforcements, which are pillar components, without requiring a box-shaped duct or the like. An object of the present invention is to suppress the increase in the number of parts and the weight of the vehicle body due to the provision of the ventilation device by configuring the ventilation device using the ventilation device.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an inner space for a vertically extending reinforcement mounted on an outer surface of an inner panel and an inner panel. While the opening is communicated with the gap formed between the openings, the interior opening having a phase different from that of the opening is provided in the trim to communicate the gap with the vehicle interior. In addition, an outer opening for communicating an outer space formed between the reinforcement and the outer panel with the outside of the vehicle is provided in the outer panel, and formed between a sealing member that limits downward expansion of both spaces and a lower end of the reinforcement. The inner space and the outer space are connected via the slit. In addition, a sealing member for limiting the upward expansion of the inner space above the opening and a sealing member for limiting the forward expansion of the outer space are provided. Further, in the present invention, it is preferable that the sealing member that limits the expansion of the inner space and the outer space is formed of a highly elastic closed foam.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic perspective view showing an embodiment of a vehicle ventilation device according to the present invention, and FIG.
3 is a sectional view taken along line BB of FIG. 2, and FIG. 4 is a sectional view taken along line CC of FIG.

[0007] In these figures, the pillars of the car are:
It is composed of an inner panel 1 and an outer panel 2,
A reinforcement 3 along the vertical direction is welded and fixed to the outer surface of the inner panel 1 to reinforce the pillar. In addition,
The reinforcement 3 is molded into a hat-shaped cross section, and the reinforcement 3 and the inner panel 1 form an inner space 4 extending in the vertical direction.

A trim 5 is arranged inside the inner panel 1 to form a gap 6 therebetween, and an opening 7 for communicating the gap 6 with the inner space 4 is provided in the inner panel 1. The gap 6 communicates with the vehicle interior by providing the interior opening 8 having a phase different from that of the opening 7 in the trim 5.

An outer panel 10 is provided in the outer panel 2 for communicating an outer space 9 formed between the reinforcement 3 and the outer panel 2 to the outside of the vehicle. Reference numeral 11 denotes a grill attached to the outdoor opening 10.

On the other hand, a sponge 12 is inserted into the inside of the reinforcement 3 as a sealing member for restricting the expansion of the inner space 4 above the opening 7 and the outer space 9
The sponge 13 is sandwiched and held between the reinforcement 3 and the outer panel 2 as a sealing member for restricting the front panel from spreading forward. A sponge 14 is attached between the inner panel 1 and the outer panel 2 in a state where the sponge 14 is in contact with the lower end of the reinforcement 3 as a sealing member for restricting the downward expansion of the inner space 4 and the outer space 9. By providing the notch 15, the lower end of the reinforcement 3 and the sponge 14
An inner space 4 and an outer space 9 are connected through the slit 16.

Reference numeral 17 is a floor panel, 18 is a back panel, 19 is a floor side panel, and 20 is a floor carpet.

As described above, the gap 6 connected to the vehicle interior a through the interior opening 8 and the outer space 9 connected to the exterior b through the outdoor opening 10 form the slit 16, the inner space 4, and the opening. 7, the vehicle compartment a
The communication between the vehicle and the outside b is maintained, and the desired ventilation action is performed.

Further, the air flowing between the inner space 4 and the outer space 9 is forced to change its direction due to collision with the sponge 14 in addition to the throttle action by the slit 16. Therefore, without using a separate part such as a duct,
It is possible to effectively prevent the flow of noise and foreign matter while ensuring the gentle air flow between the spaces 4 and 9. Therefore, even if water droplets or dust enter the outside space 9 from the outdoor opening 10 together with the air, these do not enter the vehicle compartment a via the inside space 4 and the gap 6.

As shown in the embodiment, the inner space 4
When the sealing member that limits the expansion of the outer space 9 is made of a highly elastic independent foam such as sponges 12, 13, and 14, the weight of the sealing member can be reduced, and moreover, each space 4, Regardless of the dimensional accuracy of 9, the desired sealing effect can be easily obtained by utilizing the deformation action of the sponges 12, 13, 14. In addition, since the independent foam with high elasticity has excellent sound absorbing properties, the effect of preventing the invasion of noise can be enhanced. In addition, since the independent foam is used, it is possible to avoid problems such as penetration of moisture. However, these sealing members do not necessarily need to be formed of a highly elastic closed foam, and a conventionally known sound absorbing material or the like can be used.

Further, in the embodiment, since the outdoor port 10 is provided on the rear surface of the pillar, the sponge 13 is sandwiched between the reinforcement 3 and the outer panel 2 to limit only the forward expansion of the outer space 9. However, when the outdoor opening 10 is provided, for example, on the side surface of a pillar, it is desirable to provide a sealing member that restricts the rearward expansion of the outer space 9 to prevent the outer space 9 from becoming unnecessarily large. It is.

[0016]

As is clear from the above description, in the present invention, the ventilation duct is formed by effectively utilizing the inner panel, the outer panel and the reinforcement which are the components of the pillar. As described above, there is no need to provide a box-shaped duct of an independent part, and the number of parts and the weight of the ventilation device can be reduced.
