Description

[Detailed Description of the Invention] The present invention relates to a mudguard device that prevents splashing of water, mud, etc. splashed up by automobile tires.

When the circumferential rotational speed of a tire increases as the vehicle travels, water, mud, etc. adhering to the tire are scattered by the centrifugal force caused by the rotation of the tire. In order to prevent such splashing of water or mud (hereinafter referred to as "splash"), a tire house has conventionally been formed using a fender or the like.

However, when a tire house is formed using a fender or the like as described above, air flows within the tire house as the tire rotates. Therefore, while large-mass water droplets cross the air flow and adhere to the inner surface of the fender, etc., small-mass splashes may ride on the air flow and flow out to the outside of the tire house. be.

Also, when a car runs, air turbulence occurs on the sides of the car. Therefore, the splash that flows out from the tire house is blown up by the air turbulence and adheres to the side of the vehicle body, staining it, damaging the appearance of the vehicle or staining the clothes of passengers getting in and out of the vehicle. It was hot.

This invention was made in view of the above, and
Focusing on the fact that when splatter is generated, the flow of air that flows along the inner surface of the fender that forms the tire house becomes stronger, and actively utilizes this airflow to at least flow the splatter to the outside of the vehicle body. The purpose is to prevent dirt on the side of the vehicle body.

The present invention will be described below with reference to illustrated embodiments.

In the figure, 1 is a fender attached to the cab 2 of an automobile, and a splash board 3
Together with the side splash board 4, a tire house 5 is formed. 6 is a floor panel of the cab 1, 7 is a floor side panel, 8 is a rear corner panel, 9 is a main sill, and 10 is a front wheel.

Here, a plurality of protrusions 11 are provided on the inner surface of the fender 1, that is, the surface facing the front wheel 10.
is formed. The protrusion 11 is provided so as to be inclined toward the center of the vehicle body toward the front in the rotational direction of the front wheel 10.

Therefore, the air flow generated in the tire house 5 as the front wheel 10 rotates is gradually guided toward the center of the vehicle body by the guiding action of the protrusions 11 on the inner surface of the fender 1. For this reason, the splash thrown up by the tires from the road surface is guided deep into the tire house 5 by riding on the air flow. As a result, there is no risk of splash flowing out to the outside of the tire house 5 as in the conventional case, and staining of the side surface of the vehicle body is prevented.
Incidentally, the splash that has been guided to the innermost part of the tire house 5 is attracted to the vicinity of the inner end of the fender 1 or the side splash board 4 and is discharged toward the space between the vehicle body and the ground.

In the embodiment shown in FIGS. 1 to 4, a member having an L-shaped cross section is welded and fixed to the inner surface of the fender 1 to form the protrusion 11. However, as shown in FIG. By forming the protrusion 11 with a beat with a portion of the fender 1 protruding inwardly, an increase in the weight of the fender 1 due to the provision of the protrusion 11 can be prevented.

Furthermore, the protrusions 11 provided on the inner surface of the fender 1 as described above not only serve to guide the splash as described above, but also to reinforce the fender 1. Therefore, if a protrusion is provided on the same fender as a conventional fender, the strength and rigidity of this fender can be increased, and conversely, if you want to obtain a fender with the same level of strength and rigidity as the conventional fender, It is possible to reduce the weight by reducing the plate thickness.

Further, in the embodiment, the present invention is applied to a front fender, but it goes without saying that it can also be applied to a rear fender.

As explained above, according to the present invention, the front side is closer to the center of the vehicle body than the rear, so that the air flow induced as the tire rotates is deflected toward the center of the vehicle body on the inner surface of the fender that forms the tire house. Despite the extremely simple structure of providing a protrusion that is displaced to the side, it is possible to prevent splash from flowing out from the tire house, thereby preventing staining of the side surface of the vehicle body.
