Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a floor panel structure of a vehicle,
In particular, it relates to the structure of a floor carpet laid on a floor panel provided with an opening for draining water.

(Prior Art) FIG. 4 shows a floor structure of a conventional vehicle.

In the figure, reference numeral 1 denotes a floor panel, which is provided with a recessed portion 2 which is recessed downward with respect to the upper surface of the floor panel 1. The inner bottom of the recessed portion 2 has an opening 3 for draining water. Has been drilled. Then, from the opening 3, it is possible to drain the paint remaining after the electrodeposition coating at the time of manufacturing and the water that has entered the vehicle interior during heavy rain. Further, a plug 4 can be fitted into the opening 3 so that water can be prevented from entering from the lower side of the floor panel 1 into the passenger compartment when the vehicle is traveling. Here, the plug 4 is formed by integrally molding rubber so as to have a bottomed cylindrical shape, and flange-shaped locking portions 4a and 4b are provided on the outer circumferences of the base end portion (bottomed portion) and the tip end portion thereof. Are formed respectively.
The plug 4 is mounted by fitting the plug 4 into the opening 3 from above the floor panel 1.

Further, in this floor structure, a mel sheet 5 is laid on the floor panel 1 for soundproofing and heat insulation in the vehicle interior. The mel sheet 5 is provided with an opening 5a at a portion corresponding to the recess 2 so that the plug 4 can be attached and detached through the opening 5a.

Then, in this floor structure, the floor carpet 6 is laid on the mel sheet 5.

(Problems to be solved by the invention) However, in such a floor structure, since the floor carpet 6 has low rigidity and does not have a resistance force against a load from above, a person is placed on the concave portion 2. If the luggage is loaded or the luggage is loaded, the floor carpet 6 bends downward, and the load is applied to the plug 4. As a result, the plug 4 may fall off the floor panel 1 or the plug 4 itself may be damaged. As a result, the waterproofness may deteriorate, and the water that has traveled under the floor panel 1 when the vehicle is traveling may enter the vehicle interior. There was a risk of doing it.

The present invention has been made in view of the above point, and an object thereof is to provide a floor structure that can effectively prevent the plug from falling off or being damaged, and can improve the waterproof property.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a floor panel having an opening for draining water, and a plug fitted in the opening, and a floor panel on the floor panel. In a floor structure of a vehicle including a floor carpet laid so as to cover the plug, the plug-covered portion of the floor carpet has rigidity.

(Operation) According to the above-mentioned means, the rigid portion of the floor carpet can bear the load from above, and the load applied to the plug can be reduced. Therefore, the plug is prevented from falling off the floor panel and the plug is damaged. Can be effectively prevented, and the waterproof property can be improved.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a first embodiment of the floor structure according to the present invention.

In the figure, reference numeral 11 represents a floor panel,
The floor panel 11 is provided with a recess 12 that is recessed downward with respect to the upper surface of the floor panel 11, and an opening 13 for draining water is formed in the bottom of the recess 12. And
Through this opening 13, it is possible to drain the paint remaining after the electrodeposition coating at the time of manufacture and the water that has entered the vehicle interior during heavy rain. Further, a plug 14 can be fitted into the opening 13 to prevent water from entering from below the floor panel 11 when the vehicle is traveling. Here, the plug 14 is formed by integrally molding rubber so as to have a cylindrical shape with a bottom, and flange-shaped locking portions 14a and 14b are provided on the outer circumferences of the base end portion (bottom portion) and the tip end portion thereof. Are formed respectively. The plug 14 is attached to the floor panel 1
This is done by fitting the plug 14 into the opening 13 from above 1.

Further, in this floor structure, a mel sheet 15 is laid on the floor panel 11 for soundproofing and heat insulation in the vehicle interior. The mel sheet 15 is provided with an opening 15a at a portion corresponding to the recess 12, and the plug 14 can be attached and detached through the opening 15a.

Then, in this floor structure, the floor carpet 16 is laid on the mel sheet 15.

In this respect, the floor structure of the embodiment is similar to that of the conventional one.

Next, the difference between the floor structure of this embodiment and the conventional structure will be described. In the floor carpet 16 of the embodiment, the plug 14 covering portion (denoted by reference character A in FIG. 1) has rigidity, The portion having this rigidity can bear a load from above. That is,
The floor carpet 16 of this embodiment is manufactured, for example, by compression-molding a material formed such that the thickness of the plug 14 coating portion is thicker than the surrounding wall pressure so that the entire thickness is uniform. To be done. As a result, in this floor carpet 16, the plug 14 closing portion has a higher density than the peripheral portion.

According to the floor structure thus configured, the plug 14
All or part of the load applied from above the floor carpet is carried by the rigid portion of the floor carpet, and the load applied to the plug 14 itself can be reduced. As a result, the plug 14 is prevented from falling off the floor panel 11. At the same time, it is possible to prevent the plug 14 from being damaged due to the load, and consequently to improve the waterproof property.

Further, FIG. 2 shows a second embodiment of the floor structure according to the present invention.

The floor structure of this embodiment differs from that of the first embodiment in that the rigid portion of the floor carpet 16 is formed by embedding the core material 16a in the floor carpet 16. That is, in the floor structure of this embodiment, the core material 16 made of a plastic plate, a metal plate, or the like is embedded in the portion of the floor carpet 16 that is to be the rigid portion.

According to the second embodiment, the same effect as that of the first embodiment can be obtained, and since the core material 16a is embedded, the rigidity thereof is further increased as compared with the first embodiment. Can be increased.

Incidentally, the floor carpet 16 of the second embodiment is particularly effective when applied to the floor structure shown in FIG.

That is, in this floor structure, the opening 1 of the floor panel 16 is
The reason for this is that the plug 14 is fitted into the plug 3 from the lower side of the floor panel 11, so that the plug 14 is particularly likely to fall off.

The present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the invention. For example, the floor carpet 16 of the first embodiment can be applied to the floor structure shown in FIG. Further, in the above embodiment, the plug 14 of the mel sheet 15 is used.
Although the description has been given of the case where the opening 15a is provided in the corresponding portion, the present invention can be applied even when the mel sheet 15 having no such opening 15a is used. That is, in this case, the mel sheet 15 itself has rigidity, but the floor carpet 16 as described above is used.
It becomes possible to further increase the rigidity of the plug-covered portion by adding. Also, floor carpet 1
A plate material may be adhered to 6 to increase the rigidity.

(Effect of the Invention) As is apparent from the above description, according to the present invention, a floor panel having an opening for draining water and a plug fitted in the opening, and a floor panel on the floor panel. In a floor structure of a vehicle including a floor carpet laid so as to cover the plug, since the plug-covered portion of the floor carpet has rigidity, the rigid portion of the floor carpet bears a load from above. It is possible to reduce the load applied to the plug, and as a result,
It is possible to effectively prevent the plug from falling off the floor panel and effectively prevent the plug from being damaged, and thus improve the waterproof property.
