Description

  The present invention relates to aero parts for automobiles. In particular, the present invention relates to an aero part attached to the lower part of a car body of an automobile.

  Conventionally, in an automobile, aero parts are sometimes attached to the lower part of a vehicle body including a front bumper, a side step (side panel), a rear bumper, and the like. These aero parts are also called aero dams, spoilers, skirts, sills, mudguards, etc., and have an aero parts body integrally formed of plastic, etc., and attachment means for attaching the aero parts body to the lower part of the vehicle body. Mainly provided (see, for example, Patent Document 1).

  This aero part has two main roles. The first role is to improve the aerodynamics (aerodynamic characteristics) of automobiles. This is because when the car travels at high speed, air flows between the vehicle body and the road surface, and lift is generated in the car, but by attaching aero parts to the lower part of the car body, the flow of air Is to secure the steering performance and stability of the automobile.

  The second role is to improve the appearance of the automobile. This means that by attaching various aero parts to the lower part of the car body, the original car body is differentiated in terms of appearance, or the car is partially changed to the user's favorite appearance. is there. In particular, by attaching aero parts to the lower part of the vehicle body, the entire vehicle body is kept low in appearance, and there is also an effect of giving a daring and sporty impression to the viewer.

  However, the above prior art mainly has the following disadvantages. When this aero part is installed in a car, the aero part is attached to the lower part of the car body, so the clearance between the aero part body and the road surface is narrow, and when crossing on a railroad crossing or sidewalk, steps such as curbs and gradients When the road suddenly goes up and down, it sometimes interferes with the road surface, and the lower part of the aero parts body is often scratched, cracked or lost. In this case, since the aero parts main body is integrally formed, even if the scratches, cracks and defects are only near the lower part of the aero parts main body, the aero parts main body must be removed and replaced, As an owner, maintenance costs were to increase. Moreover, as a person who replaces the aero parts, the entire aero part main body, which is bulky because it is integrally formed, has to be handled, and the handling becomes troublesome and time-consuming.

  Here, it is possible to make the aero parts main body made of a relatively soft resin so that the aero parts main body is less likely to be scratched, cracked or broken, but in this case, the rigidity of the aero parts main body is weakened. There was a problem that the shape of the aero part main body was easily deformed.

  In addition, since this aero part also has a design role as described above, the owner of the car may want to change the appearance of the aero part body according to the preference and fashion at that time, Since the aero parts body is integrally formed, the aero parts body must be removed and replaced. This also increases the cost for the automobile owner, and is troublesome for the person performing the replacement work. It was supposed to take.

  In view of the above circumstances, an object of the present invention is to provide an aero part for an automobile that can reduce maintenance costs and can easily enjoy various appearances.
