Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a spark-ignition internal combustion engine (hereinafter referred to as " spark-ignition internal combustion engine "

The present invention relates to an undercover structure, and more particularly, to an undercover structure that improves aerodynamic performance and NVH (Noise Viration Harness: noise and vibration) performance by being mounted under a spare tire wheel well panel of an automobile, And a lower undercover structure for a spare tire wheel well that is capable of contributing to weight reduction and durability improvement.

Generally, a spare tire is provided in a vehicle so that it can be replaced with an extra tire in an emergency such as a puncture caused by a timer wear or various factors while driving.

Such a spare tire is usually mounted on a wheel well located at a lower portion of a trunk of a vehicle, and related technologies are disclosed in Korean Patent Publication Nos. 1992-000069 and 2005-0058271.

On the other hand, the undercover of a vehicle protects various components provided in the lower part of the vehicle body, reduces the resistance to air when the vehicle is running, can block the non-product on the road surface, .

These under covers are normally mounted on the front bumper lower crossmember to improve the aerodynamic performance of the vehicle and to protect the interior parts of the engine compartment, thereby protecting the engine and chassis components from other foreign matter or protrusions on the ground while the vehicle is running, Smooth air flow at the bottom of the vehicle.

Here, an aerodynamic force means reducing the resistance of the air, in other words, improving airflow.

A number of patent technologies are disclosed as related undercover related technologies, such as Published Patent Application No. 2005-0024653 and Publication No. 2006-0003423.

However, since the lower portion of the wheel well in which the spare tire is housed is provided with the under cover 10 in the form as shown in FIG. 1, the air resistance is excessively generated, resulting in a disadvantage that the aerodynamic force of the vehicle is lowered.

That is, as shown in the drawing, the under cover 10 mounted on the lower part of the wheel well panel 20 is mounted to cover the wheel well panel 20 protruding downward from the vehicle body frame 30, It is impossible to control the airflow flowing from the front of the automobile, so that the air resistance is excessively generated and the aerodynamic force is lowered.

In particular, such a structure does not maximize the straightness and safety at the time of traveling, and increases the air resistance even at the rear bumper 40, which is one of the causes of increasing the fuel efficiency of the vehicle.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to improve the shape of an under cover mounted under a spare tire wheel well panel, The present invention provides a spare tire wheel well under-cover structure which can improve the fuel efficiency of a vehicle while preventing a decrease in aerodynamic force and thereby ensure a more stable driving performance.

Another object of the present invention is to achieve weight reduction and durability enhancement by manufacturing an under cover provided under a spare tire wheel well panel with a glass fiber reinforced thermoplastic resin.

According to the present invention, there is provided an under cover mounted on a lower portion of a wheel well panel for storing a spare tire of an automobile, the under cover comprising: Wherein the undercover is formed in a streamlined shape so as to guide the air introduced from the front of the lower portion of the automobile to the rear end smoothly without causing collision or vortex.

At this time, the under cover includes a downward inclined portion extending obliquely downward from the vehicle body frame; A round portion connected to an end of the downwardly inclined portion and rounded with a predetermined curvature toward the rear of the automobile; And a convex horizontal part connected to the end of the round part and extending horizontally and partially protruding downward convexly.

The undercover is also characterized by being formed of a glass fiber-reinforced thermoplastic resin.

According to the present invention, it is possible to reduce aerodynamic drag at the lower portion of an automobile to prevent aerodynamic deterioration, improve NVH performance, and improve driving stability and fuel economy of an automobile.

Further, the under cover provided under the spare tire wheel well panel is made of a glass fiber-reinforced thermoplastic resin, thereby achieving weight reduction and durability enhancement.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exemplary view showing an example of an under cover installation under a spare tire wheel well panel according to the prior art; FIG.
2 is an exemplary view showing an example of an under cover installation under a spare tire wheel well panel according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

As shown in FIG. 2, the spare tire wheel well lower under cover 100 according to the present invention is made of a glass fiber-reinforced thermoplastic resin.

Since the glass fiber-reinforced thermoplastic resin is a composite material called 'GMT' and has a high temperature durability, a tensile strength and an impact strength and is lightweight, the weight saving effect can be obtained compared with steels. Therefore, the under cover 100 according to the present invention It is suitable for use.

In particular, the glass fiber-reinforced thermoplastic resin is formed into a sheet shape, and can be easily and quickly formed with various shapes by hot molding through a mold, and is excellent in workability.

In the present invention, the under cover 100 is manufactured to have a streamlined shape as shown in FIG. 2 by using such a material.

In addition, the under cover 100 is mounted on the outer side of the lower portion of the wheel well panel 200 in which the spare tire is housed to protect the lower portion of the wheel well panel 200 to minimize the resistance of the lower portion of the vehicle.

For this purpose, the under cover 100 includes a downward slope 110, a round portion 120, and a convex horizontal portion 130.

The downward incline part 110 is a part extended from the vehicle body frame toward the rear side, that is, toward the rear bumper when extending toward the ground, and is an introduction part for realizing the under cover 100 in a streamlined manner.

The round portion 120 is connected to the lower end of the downwardly inclined portion 110 and has a predetermined curvature and is rounded.

Accordingly, the air introduced through the lower portion of the automobile from the front is naturally moved along the inclined surface while contacting with the downward inclined portion 110, and when the moving portion 120 is moved while rapidly moving in the direction, And moves toward the rear of the automobile along the bottom surface of the vehicle 100.

At this time, the bottom surface of the under cover 100 forms a convex horizontal part 130 which extends horizontally in a state of protruding a little convexly. The convex horizontal part 130 extends through the round part 120 Direction The swirled inflow air is convexly processed to make the horizontal part without increasing the deviation of the curvature so that the swirling air can be quickly escaped without securing the straightness without causing vortex.

Therefore, the air that has exited the round portion 120 smoothly flows along the surface of the convex horizontal portion 130 without causing vibration or flow velocity deviation, and thus flows quickly and smoothly.

Therefore, the air resistance applied to the under cover 100 causes a sharp decrease compared to the conventional one, which leads to an effect of reducing NVH performance, that is, noise and vibration.

Moreover, since the impact is reduced due to the air collision and smooth air flow is ensured, it also contributes to improving the fuel economy.

As described above, the under cover 100 according to the present invention improves the shape and material of the under cover 100, thereby contributing to the straight stability of the automobile, thereby enhancing the driving stability at the time of high-speed driving while improving the aerodynamic performance.
