Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a front bumper of an automobile, and particularly to a front bumper equipped with an air spoiler.

(Prior Art) In recent years, automobile manufacturers have responded to the diversification and individualization of users by attaching various optional parts to basic vehicle models.

For example, by installing an air spoiler on the front bumper, the grade of a car is raised or the car is made to look sporty.

By the way, the mounting structure for installing an airdam spoiler on the front bumper is generally two types: a mounting structure in which only the airdam spoiler is retrofitted to the front bumper of a basic car model that is provided with an airdam spoiler mounting part (for example, a bolt hole), and a mounting structure in which only the airdam spoiler is retrofitted to the front bumper of a basic car model that is provided with an airdam spoiler mounting part (for example, a bolt hole part).
As described in Publication No. 34050, there was a mounting structure in which a front bumper integrally formed with an air damp spoiler was replaced with a front bumper without an air damp spoiler.

For example, in Japanese Patent Application Laid-Open No. 62-68158, a locking edge formed on the upper end of the spoiler body is fitted into a terminal receiving groove formed on the vertical wall of the front bumper, and a bracket on the rear side of the upper part of the spoiler is attached to the front bumper. The front spoiler mounting structure is described, which is fixed with bolts and nuts.

(Problem that the invention aims to solve) With the above-mentioned mounting structure in which only the air spoiler is retrofitted to the front bumper, in the condition of the basic car model where the air damp spoiler is not installed, the air spoiler mounting part remains exposed on the surface of the front bumper, which deteriorates the appearance. As a result, there was a problem that the product value of the basic car model decreased.

In addition, in the former publication mentioned above, after the front bumper is removed from the basic car model,
It is necessary to install a front bumper with an integrated air spoiler, which takes time and effort to install and remove.

In the front spoiler mounting structure described in the latter publication, the locking edge at the upper end of the spoiler is fitted into the terminal receiving groove of the front bumper. the inability to securely fix the
There are problems such as poor assembly when fixing the bracket on the back of the upper part of the spoiler to the front bumper with bolts and nuts.

The purpose of this invention is to provide a mounting part for attaching an airdam spoiler that does not damage the appearance of the bumper face, allows the airdam spoiler to be mounted as necessary, and allows the airdam spoiler to be mounted securely and easily. The purpose of the present invention is to provide a front bumper for an automobile.

(Means for Solving the Problems) The front bumper of an automobile according to the present invention covers the lower front end of the vehicle body at the lower part of the bumper face of the front bumper, and has an air dam spoiler attached to the lower front of the bumper face. The spoiler includes an upper wall portion facing rearward from the upper end and a bottom wall portion extending rearward from the lower end, and a plurality of hook portions are provided on the edge of the upper wall portion at appropriate intervals in the vehicle width direction. A hinge part extending between the left and right ends of the air spoiler is formed at an intermediate position of the bottom wall part, and a fixing part is formed at the edge of the bottom wall part,
A slit-shaped groove that opens forward over the entire width is formed in the lower part of the bumper face, and a plurality of insertion holes corresponding to the plurality of hooks of the air spoiler are formed in the bottom wall of the groove. At the same time, an engagement hole is formed in the bottom wall of the bumper face corresponding to the fixing part of the airdam spoiler, and the hook part of the upper edge of the airdam spoiler is fitted and locked into the fitting hole, and the airdam spoiler is inserted into the engagement hole. The fixed part is fixed.

(Function) Since the automobile bumper according to the present invention is constructed as described above, when the front bumper is not provided with an air spoiler, the fitting hole into which the hook portion at the upper end of the air spoiler is fitted and locked is formed into a slit-shaped groove. Since it is installed on the bottom wall of the bumper, it does not appear on the bumper surface.

Furthermore, when attaching an airdam spoiler to the front bumper, the upper end of the airdam spoiler can be firmly fixed to the bumper by fitting the upper end edge of the airdam spoiler into the groove and engaging the hook portion with the insertion hole. In addition, since a hinge part extending between the left and right ends of the airdam spoiler is formed at an intermediate position of the bottom wall part of the airdam spoiler, the fixing part of the airdam spoiler can be easily aligned with the engagement hole of the bumper face. Excellent assembling performance.

(Effect of the invention) According to the automobile bumper of the invention, as explained above, the insertion hole for locking the hook portion at the upper end of the air damp spoiler is provided in the bottom wall of the slit-shaped groove formed in the bumper. Since the slit-shaped groove only appears on the front of the front bumper as part of the design when the airdam spoiler is not installed, the inset hole for installing the airdam spoiler is not exposed and the product value is reduced even on car models where the airdam spoiler is not installed. It never declines.

Moreover, when attaching the upper end of the airdam spoiler to the front bumper, the upper edge of the airdam spoiler is fitted into the groove and the hook part is inserted into the insertion hole and locked, so the upper end of the airdam spoiler can be securely fixed to the bumper face. The upper end of the airdam spoiler can be attached by simply fitting the hook part into the fitting hole and locking it, and the fixing part can be inserted into the fitting hole through the hinge part of the bottom wall of the airdam spoiler. Since positioning can be done easily, the efficiency of airdam spoiler installation work can be greatly improved.
