BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rust preventive wheel cover for an automobile and a method of manufacturing the same. More specifically, the present invention relates to a rustproof wheel cover for automobile having a structure that can be easily mounted and detached, ≪ / RTI >

The surface of a disc of a brake device applied to an automobile is exposed to external air and rainwater. Therefore, when the brake is not used for a long time in the motor pool after the vehicle is shipped from the motor pool, the surface of the disk is rusted due to oxidation reaction with air and inflow of rainwater.

Since the rust generated at this time causes the braking performance of the brake to deteriorate and the color of the rust on the surface of the disc is mostly red, the rust on the surface of the disc, which can be easily seen from the outside of the vehicle, .

In order to prevent the rust-preventive phenomenon of the surface of the brake disk as described above, the wheel of the vehicle is covered with a rust-proof wheel cover.

BACKGROUND ART Conventionally, a rust-proof wheel cover for an automobile is generally made of an ABS material, and has a circular cross-section corresponding to the vehicle wheel and has a spoke portion corresponding to a spoke of the vehicle wheel, And an engaging portion formed concavely from the spoke-shaped portion.

Accordingly, the rust-preventive wheel cover is forcibly press-fitted so as to cover the vehicle wheel from outside, and the rust-preventive wheel cover is positioned so as to cover the vehicle wheel with the spoke portion of the rust-preventive wheel cover being aligned with the spokes of the vehicle wheel , And the fitting portion is forcibly press-fitted into the space between the spokes of the vehicle wheel.

However, in recent years, the design of a wheel of an automobile such as a spoke type wheel, a mesh type wheel, a bish type wheel, a fin type wheel, an aero type wheel, Accordingly, the rim width, offset, and the like of the vehicle wheel are various, and accordingly, the rust-proof wheel cover is also made variously according to the wheel design.

That is, in the case of the conventional rust-preventive wheel cover, it is not possible to commonly use various wheel styles, and a rust-proof wheel cover having a new structure must be manufactured every time the wheel design is changed.

On the other hand, another conventional rust-proof wheel cover is made of a film sheet and attached to the wheel of the vehicle. In this case, however, due to the adhesive component in the film, there is a problem of discoloring in the case of a wheel with a special coating. In addition, the film must be discarded after one use, which leads to an increase in costs and environmental problems. In addition, since the process of attaching the rust-preventive wheel cover of the film material to the vehicle wheel requires a separate jig, it is difficult to attach the rust-proof wheel cover and the time is also increased. Further, there is a problem that the time for desorbing the attached film is also increased.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and it is an object of the present invention to provide a rust preventive wheel cover for a vehicle and a method for manufacturing the same that can be used regardless of various wheel designs such as rim width, The purpose.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a rust-preventive wheel cover for a vehicle and a vehicle wheel according to a preferred embodiment of the present invention, and FIG. 2 is a front view of the rust-preventive wheel cover of FIG.

1 and 2, a rust-proof wheel cover 100 for a vehicle according to a preferred embodiment of the present invention covers the vehicle wheel 10 to protect the vehicle wheel 10 from the outside. In this case, the wheel 10 includes a rim 12 and a wheel coupling means 14. In the rim 12, a wheel hole 16 is formed on the same circumference from a specific center. In this case, the specific center is the center of the hub hole 18, which is usually the rotation axis of the automobile tire. The wheel engaging means 14 is inserted into the wheel hole 16 to engage between the vehicle hub (not shown) and the rim 12, and may be a wheel bolt or a wheel nut.

A rustproof wheel cover 100 for a vehicle according to a preferred embodiment of the present invention includes a cover 110 and a coupling 120. The cover portion 110 is arranged to cover the outer surface of the rim 12. The engaging portion 120 protrudes from the cover portion 110 in the direction of the rim 12 in conformity with the wheel engaging means 14. The engaging portion 120 has a fitting hole 121 Is formed.

According to the present invention, the rust-preventive wheel cover 100 is formed such that the wheel coupling means 14 is fitted therein. The wheel coupling means 14 is determined in accordance with the wheel standard. That is, a hub hole 18 is formed at the center of the rim 12, a wheel hole 16 is formed on the same circumference with the hub hole 18 as a center, Is inserted into the hole (16) and engaged with a stud fixed to the axle to fix the wheel to the hub of the axle. The diameter of the circle connecting the center line of the wheel hole 16 is referred to as PCD (pitch center diameter). If the PCD and the wheel inches are the same, the number of the wheel holes 16 is standardized in spite of various wheel designs , And accordingly the position of the wheel coupling means 14 is also standardized.

Therefore, the rust-preventive wheel cover 100 can be commonly used regardless of the shapes of the various wheels 10 by being coupled to the wheel-engaging means 14 in a standardized position.

3 is a cross-sectional view taken along the line III-III in Fig.

3, the height at which the wheel engaging means 14 protrudes from the wheel hole 16 is determined according to the shape of the wheel engaging means 14 or the offset of the rim 12. As shown in Fig. In the present invention, the rim 12 can be shared by the wheel coupling means 14 by projecting the coupling portion 120 from the cover portion 110 at an appropriate height. That is, the height of the engaging portion 120 protruding from the cover portion 110 is determined by the degree to which the wheel hole 16 is offset in the rim 12 and the degree to which the wheel engaging means 14 is extended from the wheel hole 16 It may be varied depending on the protruded length. It is preferably 32 mm to 38 mm, more preferably 33 mm to 36 mm, and can also be commonly used for wheels of various designs.

In this case, the coupling portion 120 may include a first bent portion 122 and a second bent portion 124. The first bent portion 122 is disposed to be bent from the cover portion 110 in the wheel direction. The second bending portion 124 is bent from the first bending portion 122 to be parallel to the cover portion 110, and the fitting hole 121 is formed at the center.

In this case, it is preferable that the fitting hole 121 has a smaller diameter than the width of the wheel coupling means 14. This is because the wheel coupling means 14 is forcedly fitted in the fitting hole 121, so that the fitting force is excellent. In this case, when the second bending portion 124 is mounted on the wheel coupling means 14, the second bending portion 124 may be curled in the direction of the cover portion 110 to be in contact with the wheel coupling means 14, .

In this case, the second bent portion 124 may include a plurality of contact portions 125. The contact portions 125 are separated from each other, and the free ends of the contact portions 125 are combined to form an outer shape of the insertion hole 121 as a whole. As a result, the wheel coupling means 14 can be mounted to the fitting hole 121 with a smaller force, and the elastic force is also excellent, so that the wheel coupling means 14 can not be detached. In addition, since the contact portions 125 are separated from each other, the wheels can be mounted regardless of the width of the wheel coupling means 14. [

In particular, the rust-preventive wheel cover 100 may be made of a thermoplastic resin material such as polypropylene (PP) having a certain elastic force. Since the thermoplastic resin is easy to mold and has elasticity, the thermoplastic resin is flexibly bent without being broken when the wheel coupling means 14 is mounted, and is not easily released to the outside after mounting.

The rust preventive wheel cover 100 may have a thickness D of about 1 mm. In this case, it is preferable that the thickness of the second bent portion 124 is thinner than that of the cover portion 110. This is because the cover portion 110 has a thickness sufficient to protect the rim 12, The two bent portions 124 have excellent elasticity and flexibility.

Accordingly, as shown in Figs. 4A to 4C, if the wheel inches are the same irrespective of the various shapes of the wheel engaging means 14, the wheel can be mounted.

The engaging portion 120 may further include ribs 128 formed along the longitudinal direction or the width direction of the first bent portion to improve the strength thereof. This is more effective when the second bent portion 124 is composed of a plurality of contact portions 125. In this case, the ribs 128 may be disposed along the longitudinal direction of the first bent portion 122.

The cover portion 110 may also have ribs 118, which may be more rigid.

The cover 110 and the coupling part 120 may be formed of separate products. That is, the coupling part 120 may be attached to the cover part 110 in the form of a cup having, for example, a hollow at the bottom.

Alternatively, the engaging portion 120 and the cover portion 110 may be integrally formed. That is, it is preferable that the engaging part 120 is bent and extended from the cover part 110 by vacuum molding or the like so as to be made of a single mold, thereby shortening the manufacturing time and reducing the mold cost and material cost.

Hereinafter, a method of manufacturing the automotive rust-preventive wheel cover 100 according to the embodiment of the present invention will be described. In order to manufacture the rust preventive wheel cover 100 according to the preferred embodiment of the present invention, a first type having a shape adapted to the cover portion 110 and a second type having a shape matching the cover portion 110, A step of preparing a mold having a second mold having a concave shape on the mold frame, placing a sheet for a rust preventive wheel cover 100, which is a thermoplastic resin, on the mold, 100) sheets are closely contacted with each other to form the joining portion 120.

As shown in FIG. 5, the first type 2 having a shape aligned with the cover portion 110 and the first type 2 having a shape corresponding to the coupling portion 120, (1) having a second mold (3) having a concave shape in the mold (2).

The second mold (3) has a concave shape from the first mold (2). That is, it is preferable that the mold 1 molds the rust-preventive wheel cover 100 using a mold 1, because the second mold 3 is formed by the first mold 2, The stress concentration in the bending portion at the time of molding the rust preventive wheel cover 100 is not so large as compared with the case where the bushing has a convex shape in the rust preventing wheel cover 100, In this case, ribs 2a and 3a are preferably formed on the first mold 2 and the second mold 3 for the rigidity of the rust-preventive wheel cover 100, respectively.

Thereafter, a step of placing a sheet 100 for a rust-preventive wheel cover, which is a thermoplastic resin, on the mold 1 is carried out. In this case, the rust preventive wheel cover sheet 100 is heated and softened, and then placed on the first mold 2 and the second mold 3. Examples of the thermoplastic resin include PP.

Thereafter, as shown in FIG. 6, the first and second molds 2 and 3 and the rust-preventive-wheel cover 100 are closely contacted to form the rust-preventive-wheel cover 100. In this case, the gap between the first and second molds (2, 3) and the sheet is made vacuum, and the sheet is brought into close contact with the surface of the mold and cooled to mold the rust-proof wheel cover 100.

Thereafter, as shown in FIG. 7, air is sucked between the first and second molds and the sheet to take out the molded article of the rust-preventive wheel cover 100.

In this case, as shown in FIG. 8, a step of trimming the center of the coupling part 120 to have the shape of the coupling hole 121 may be further performed.
