Abstract

PROBLEM TO BE SOLVED: To improve the air flow interrupting effect of a spat in a fender liner having the spat for interrupting the air flow flowing to a tire in the front of the tire in the traveling of an automobile. SOLUTION: The spat 5 is formed into a cavity shape having the upper end opened to the plate surface of the front end 3 of the fender liner 1, and an air outlet port 6 is formed on the lower end 52 of the spat 5 to prevent backward flowing of a part of the air flow A flowing along the front surface 51 of the spat 5 along the lower end 52 by the air flow C flowing into the spat 5 and blowing down through the outlet port 6.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle fender liner, and more particularly to a fender liner provided with spats.

[0002]

2. Description of the Related Art As shown in FIG.
Is an arch-shaped, generally synthetic resin integrally molded product,
The inner peripheral edge is fixed to a fender apron (not shown) and the outer peripheral edge is fixed to an arch part of a fender panel (not shown) by bolts through a plurality of mounting holes 2 so as to cover the wheel house, and the flying stones of the tire It plays a role in preventing scattering of water and muddy water.

On the fender liner 1, a spats 5 projecting downward as shown in FIG. 3 is formed at a flat front end portion 3 so that an airflow passing through a lower portion of the vehicle body when the vehicle is running is directed forward of the tire T. There is one that cuts off the air resistance of the tire T (for example, see
No. 183271).

[0004]

However, in the conventional spats 5, a part B (broken line) of the airflow A flowing downward along the front surface of the spats 5 flows rearward without separating from the lower end of the spats 5, and the tires have the same structure. There was a problem that the resistance of T was reduced and the effect as spats was reduced.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a fender liner for an automobile that has a simple structure and further reduces the air resistance of the tire and more fully exerts the effect of spats.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a fender liner installed on a wheel arch portion of a vehicle body, which protrudes downward at a front end of the fender liner to block an airflow at the time of running of a vehicle in front of a tire. In the fender liner provided with the spats, the spats are formed in a hollow shape whose upper end is opened to a plate surface at a front end portion of the fender liner, and air that has flowed into the spats from the opening at the upper end during driving of the car is provided at the lower end of the spats. An outlet for blowing out the spats is formed below (claim 1). This allows
The air blown out from the outlet of the spats during running of the vehicle separates the airflow flowing along the lower end of the spats from the spats and flows downward.

The above-mentioned spats have a substantially U-shaped cross-section in which the width is substantially the same as or slightly smaller than the tire width, and the front-rear width tapers toward the lower end, and is formed integrally with a fender liner made of synthetic resin. The slot has a long hole-like suction port formed in the lower end surface thereof in the vehicle width direction (Claim 2). The spats of the present invention have a simple structure and can be integrally formed with the main body of the fender liner made of synthetic resin.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIG. 2 together with FIG. In FIG. 2, a fender liner 1 is formed by integrally forming a synthetic resin such as polyethylene by vacuum molding, and has an overall arch shape, an inner peripheral edge of which is an unillustrated fender apron, and an outer peripheral edge thereof is an unillustrated one. A plurality of mounting holes 2 are bolted and fixed to the arch portion of the fender panel to cover the wheel house.

As shown in FIG. 1, the front end 3 of the fender liner 1 is formed as a horizontal flat plate extending to the inner surface of a front bumper (not shown). Spats 5 projecting downward and facing the tire T are formed integrally with the front end portion 3. A bulging portion 4 having a plate surface bulging upward is formed at a position inside the spats 5 at the front end portion 3 so that ventilation to the brake device is improved when the vehicle is running, and the brake device is cooled. It is like that.

The spats 5 have a longitudinal section in the front-rear direction substantially
The upper end has an opening 50 in the plate surface of the front end 3.
Is formed. The front surface 51 of the spats 5 is an inclined surface extending obliquely rearward and downward, and its extension is an inclined surface that does not intersect with the tire T. The rear surface 53 of the spats 5 is continuous with the arch portion of the fender liner 1.

The width of the spats 5 is substantially the same as or slightly smaller than the width of the tire T.
Reference numeral 2 denotes a height position substantially at the center of the tire T in the vertical direction. On the bottom surface 52 at the lower end of the spats 5, two long hole-shaped openings long in the vehicle width direction are formed in parallel.
Is formed.

When the vehicle is running, the airflow A from the front follows the lower surface of the front end 3 of the fender liner 1 and
Is guided downward along the front surface 51 of the tire T and is guided toward the ground E in front of the tire T. At this time, the airflow C introduced simultaneously from the ventilation port formed in the front bumper (not shown)
Enters the spats 5 through the upper end opening 50 of the spats 5, and the lower end of the outlet 6
Is sucked out and blows down. As a result, of the airflow A, the airflow B that is going to flow backward along the lower end bottom surface 52 of the spats 5 is separated from the lower end bottom surface 52, merges with the airflow A that flows downward, and flows downward.

[0013]

According to the fender liner of the present invention, the airflow cut off in front of the tire by the spats is guided to the lower side of the spats without going to the back side of the spats, so that the wind pressure acting on the tires is reduced. And the effect of spats is more fully exhibited.
