The present invention relates to a vehicle anti-rust wheel cover and a method of manufacturing the same, more specifically, the vehicle anti-rust wheel cover having a structure that can be easily installed and detached, and commonly applied to a variety of wheel shapes and its manufacture It is about a method.

Discs of brake devices applied to automobiles have their surfaces exposed to outside air and rainwater. Therefore, when the brake is not used for a long time in the motor pool after leaving the vehicle, rust occurs on the surface of the disk due to oxidation reaction with air and inflow of rainwater.

The rust generated at this time is the cause of deterioration of the braking performance of the brake, and since the color of the rust generated on the surface of the disk is mostly red, the rust on the surface of the disk that can be easily seen from the outside of the vehicle adversely affects the deterioration of the product quality of the vehicle. Will be given.

As described above, the wheel of the vehicle that is shipped to prevent the rust phenomenon of the brake disc surface is covered with a rust preventing wheel cover.

Conventionally, a vehicle anti-rust wheel cover is usually made of ABS, and has a circular cross section in accordance with the vehicle wheel, and is inserted into a space between a spoke shape corresponding to the spoke of the vehicle wheel and the spokes adjacent to each other of the vehicle wheel. And a fitting portion formed concave from the spoke-shaped portion.

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

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

As shown in Figures 1 and 2, the vehicle anti-rust wheel cover 100 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. The rim 12 is formed with wheel holes 16 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 axis of rotation of the automobile tire. The wheel coupling means 14 is inserted into the wheel hole 16 to couple between the vehicle hub (not shown) and the rim 12. The wheel coupling means 14 may be a wheel bolt or a wheel nut.

Anti-rust wheel cover 100 for a vehicle according to a preferred embodiment of the present invention includes a cover portion 110, the coupling portion 120. The cover 110 is disposed to cover the outer surface of the rim 12. The coupling part 120 protrudes in the direction of the rim 12 from the cover part 110 in accordance with the wheel coupling means 14, and the fitting hole 121 into which the wheel coupling means 14 is fitted. ) Is formed.

According to the present invention, the anti-rust wheel cover 100 is formed so that the wheel coupling means 14 is fitted. The wheel coupling means 14 is determined according to the wheel standard. That is, the hub hole 18 is formed in the center of the rim 12, the wheel hole 16 is formed on the same circumference around the hub hole 18, the wheel engaging means 14 is the wheel It is inserted into the hole 16 and engaged with the stud fixed to the axle to secure the wheel to the hub of the axle. The diameter of the circle connecting the center line of the wheel hole 16 is called the pitch center diameter (PCD), and if the PCD and the wheel inch are the same, the number of the wheel holes 16 is standardized despite the various wheel designs. Thus, the position of the wheel engaging means 14 is also standardized.

Therefore, the anti-rust wheel cover 100, by coupling to the wheel coupling means 14 in a standardized position, it can be shared regardless of the shape of the various wheels 10.

3 is a cross-sectional view taken along line III-III of FIG. 1.

As shown 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. In the present invention, the wheel coupling means 14 may be shared by the rim 12 by protruding the coupling portion 120 to an appropriate height from the cover portion 110. That is, the height of the coupling part 120 protruding from the cover part 110 is such that the wheel hole 16 is offset from the rim 12 and the wheel coupling means 14 is from the wheel hole 16. It may vary depending on the protruding length, it is preferred if the 32mm to 38mm, more preferably 33mm to 36mm can be used in common in the wheel of various designs.

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

In this case, the fitting hole 121 preferably has a diameter smaller than the width of the wheel coupling means (14). This is because the wheel coupling means 14 is forcibly fitted into the fitting hole 121, the mounting force is excellent. In this case, when the second bent portion 124 is mounted to the wheel coupling means 14, the second bending portion 124 may be in contact with the wheel coupling means 14 while being rolled toward the cover part 110. Will have

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 respective free ends are combined to form an outer shape of the fitting hole 121 as a whole. As a result, the wheel coupling means 14 can be mounted in 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 separated from the wheel coupling means 14. In addition, since the contact portions 125 are separated from each other, the wheel coupling means 14 can be mounted regardless of the width.

In particular, the anti-rust wheel cover 100 may be made of a resin material having a predetermined elastic force, for example, a thermoplastic resin material such as polypropylene (PP). Since the thermoplastic resin is easy to mold and has elasticity, when the wheel coupling means 14 is mounted, the thermoplastic resin is not broken and is flexibly bent and coupled, and is not easily detached after installation.

The antirust wheel cover 100 may have a thickness D of about 1 mm. In this case, the thickness of the second bent portion 124 is preferably thinner than the cover portion 110, which has a sufficient thickness for the cover portion 110 to protect the rim 12, The two bent portion 124 has excellent elastic force and flexibility.

Accordingly, as shown in Figures 4a to 4c, regardless of the wheel coupling means 14 of various shapes, if the wheel inches are the same can be mounted.

The coupling part 120 may further include ribs 128 formed along the length direction or the width direction of the first bent part in order 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 rib 128 may be disposed along the longitudinal direction of the first bent portion 122.

The cover part 110 may also have a rib 118, and thus may have more rigidity.

The cover unit 110 and the coupling unit 120 may be made of a separate product. That is, the coupling part 120 may be formed by being attached to the cover part 110, for example, in a cup shape having a hollow formed on the bottom.

Unlike this, the coupling part 120 and the cover part 110 may be integrally formed. That is, it is preferable that the coupling part 120 is bent and extended from the cover part 110 by vacuum molding or the like to be manufactured in one mold, thereby shortening the manufacturing time and reducing the mold cost and material cost.

Hereinafter, a method of manufacturing the anti-rust wheel cover 100 for a vehicle according to the embodiment of the present invention will be described. In order to manufacture the anti-rust wheel cover 100 according to the preferred embodiment of the present invention, the first type having a shape to fit the cover portion 110 and the first type to fit the coupling portion 120 Preparing a mold having a second shape having a concave shape, placing a sheet for preventing rust wheel cover 100 made of thermoplastic resin on the mold, and the mold and rust preventing wheel cover ( 100) the gap between the sheets is molded while being in close contact with each other to form the coupling part 120.

Each step will be described in detail with reference to the drawings. First, as shown in FIG. 5, the first type 2 having a shape that fits the cover 110 and the first type that fits the coupling part 120 are described. In step (2), the mold 1 having the second mold 3 having the concave shape is prepared.

The second mold 3 has a concave shape from the first mold 2. That is, the mold 1 is excellent in forming the anti-rust wheel cover 100 by using the mold (1) of the shape, which is the second mold (3) is the first mold (2) This is because the stress concentration at the bent portion at the time of molding the rust-proof wheel cover 100 is less than that of having a convex shape, thereby achieving excellent molding. In this case, it is preferable that the rib molds 2a and 3a are formed in the first mold 2 and the second mold 3 for the rigidity of the anti-rust wheel cover 100, respectively.

After that, a step of placing a sheet 100 for rust prevention wheel cover, which is a thermoplastic resin, is placed on the mold 1. In this case, the anti-rust wheel cover sheet 100 is heated and softened and then placed on the first mold 2 and the second mold 3. PP is mentioned as an example of the said thermoplastic resin.

Thereafter, as shown in FIG. 6, the antirust wheel cover 100 is formed by bringing the first and second molds 2 and 3 into close contact with the antirust wheel cover 100. In this case, the gap between the first and second dies 2 and 3 and the sheet is made into a vacuum, the sheet is brought into close contact with the surface of the die, and cooled to form the rust preventive wheel cover 100.

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

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