Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an exterior molded product for a vehicle that serves as a ventilator and decoration that utilizes exterior parts such as moldings and ornaments.

[Prior Art] Fig. 5 is a perspective view of a car body, and some of the decorative exterior parts such as the molding 2 and ornaments 3 attached to the side surface of the car body 1 also serve as ventilators. be.

FIG. 6 is a sectional view of a conventional vehicle ventilator shown in, for example, Japanese Utility Model Application No. 56-51616. In the figure, reference numeral 4 denotes a molded product serving as an exterior product such as a molding 2, which is attached to cover an opening 6 of a vehicle body panel 5, and has a slit 7 in a portion corresponding to the opening 6. Further, in the opening 6, a duct 9 having a ventilation path 8 rises up toward the passenger compartment 10 side.

In the conventional ventilator as described above, negative pressure is generated by the airflow flowing along the molded product 4 when the vehicle is running, and the air in the passenger compartment 10 is discharged from the slit 7 through the ventilation path 8 of the duct 9, and the air in the passenger compartment 10 is Dirty air, steam, etc. are discharged outside the vehicle. On the other hand, water droplets and the like entering from outside the vehicle are prevented from entering the vehicle interior 10 by the duct 9.

[Problem that the invention attempts to solve]

However, in such conventional ventilators, the duct 9 cannot completely prevent water from entering, so when there is heavy wind and rain or when washing the vehicle, the water that has entered may jump over the duct 9 and enter the vehicle. There was a problem in that the room 10 was contaminated and water intrusion could not be prevented by providing an open/close flap or the like in the ventilation path 8.

This invention is intended to solve the above-mentioned problems, and aims to provide a vehicle exterior molded product that is simple in structure and can be used as a ventilator and decoration to completely prevent water from entering.

[Means for solving problems]

This invention is an exterior molded product for a vehicle that serves as a ventilator and decoration that is attached to an opening in a vehicle body panel. a cylindrical penetration part that penetrates the opening and projects to the inside of the vehicle; a ventilation path that is provided within the penetration part and opens from the interior of the vehicle to the outside of the vehicle via the slit; A ventilator-cum-decoration vehicle comprising a breathable and waterproof sheet material having a micro-filter structure and having a large number of minute ventilation holes large enough to prevent air from passing through, and provided to block the ventilation passages. It is an exterior molded product.

[Effect]

The ventilator-cum-decorative vehicle exterior molded product of this invention has both the functions of a ventilator and a decorative exterior molded product, and gases such as air and water vapor in the vehicle interior are removed through the vents formed in the penetration parts. It is discharged through the tract. At this time, the sheet material provided in the ventilation passage has a large number of fine ventilation holes that are large enough to allow gas to pass through but not to allow liquid to pass through, so it is breathable and waterproof, and is able to absorb air inside the vehicle. Gas such as water vapor is discharged to the outside of the vehicle through this sheet material, while water droplets etc. that enter from the outside of the vehicle are blocked by the sheet material without passing through, and are prevented from entering the vehicle interior.

〔Example〕

This invention will be explained below with reference to embodiments of the drawings. FIG. 1 is a sectional view showing an embodiment of this invention.
FIG. 2 is a perspective view thereof, and the same reference numerals as in FIG. 6 indicate the same or corresponding parts.

The molded product 4 serves as a decorative exterior part such as the molding 2 and the ornament 3, and is a molded product body 4 that covers the outside of the opening 6 of the vehicle body panel 5.
a, penetration part 4b penetrating through opening 6, penetration part 4b
It has a flange portion 4c formed at the tip thereof, a cover portion 4d covering the flange portion 4c, and a flange portion 4e formed at the upper open end of the cover portion 4d. The slit 7 is provided in the molded product main body 4a, and the air passage 8 is provided in the through portion 4b and the cover portion 4d, and opens upward into the vehicle compartment 10.

Waterproof sheet materials 11 and 12 that have air permeability and do not allow water droplets to pass through are attached to the flange portions 4c and 4e by welding, adhesive, etc. so as to block the air passage 8. The sheet materials 11 and 12 are sheet-like materials with a microfilter structure that have a large number of fine ventilation holes that are large enough to allow gas to pass through but not to allow liquid to pass through.By adjusting the size of the ventilation holes, air can be It is adjusted to have both breathability, which allows gases such as gas and vapor to pass through, and liquid barrier properties, which block liquids without allowing them to pass through. Such sheet materials 11 and 12 are commercially available, such as Gore-Tex (manufactured by Dunlop, Inc., USA).
(registered trademark), Microtecs (manufactured by Nitto Denko Corporation, registered trademark), etc. can be used.

In the exterior molded product for a vehicle that serves as a ventilator and decoration configured as described above, air and water vapor in the vehicle interior 10 are sucked through the sheet materials 12 and 11 by the airflow flowing along the molded product 4 when the vehicle is running. , are discharged from the air passage 8 and slit 7 to the outside of the vehicle. On the other hand, even if water enters the ventilation passage 8 with great force, such as during bad weather or when washing with water, it is blocked by the sheet materials 11 and 12 and is prevented from entering the interior of the vehicle 10. In particular, when two sheet materials 11 and 12 are provided as shown in the figure, even if one sheet material 11 is damaged by water pressure or the like, the other sheet material 12 can prevent water from entering.

Fig. 3 is a perspective view of a sheet material of another embodiment;
The figure is a cross-sectional view of a part of the sheet material 11, 1.
2 has its outer peripheral edge reinforced with a frame 13 and is detachable in a plug-in manner, making it easy to assemble and replace.

In the above description, the structure, mounting position, number, etc. of the molded product 4, sheet materials 11, 12, etc. can be freely changed. Furthermore, this invention is applicable not only to moldings and ornaments, but also to general exterior parts for vehicles.

[Effect of idea]

According to this invention, a ventilation passage is provided in a decorative exterior molded product, and this ventilation passage has a microfilter structure that has a large number of fine ventilation holes that are permeable to gas but not permeable to liquid. Since the waterproof sheet material is provided, the structure is simple, and the air inside the vehicle can be discharged to the outside of the vehicle, and water can be prevented from entering from outside the vehicle. In addition, since slits are formed in the molded product body, it has excellent decorative properties, and since the cylindrical penetration part has a ventilation path, it can effectively hold the sheet material, even in the event of a rainstorm or gust of wind.
It is possible to reliably prevent water from entering, and furthermore, it has the effect of being able to serve both as a ventilator and as a decorative exterior molded product.
