Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a vehicle wheel cover mounting structure.

[Conventional technology]

FIG. 6 is a rear view of a conventional wheel cover shown in, for example, Japanese Utility Model Publication No. 61-163703, and FIG. 7 is a sectional view taken along the line AA. On the back surface of the wheel cover 1, a plurality of arc-shaped projecting pieces 2 project on the same circumference, a locking portion 3 projecting outward in an arc shape is provided at a tip end thereof, and a stopper projecting outward at an intermediate portion. 4 are provided. A concave receiving portion 5 is formed inside the locking portion 3, and a retainer 6 made of an annular wire is engaged with the receiving portion 5. The butting part 7 of the retainer 6 is joined by caulking a metal cylindrical clamp 8.

In the wheel cover 1, the retainer 6 is engaged with the receiving portion 5, the projecting piece 2 is bent and inserted into the inside of the wheel rim 9 of the road wheel, and the engaging portion 3 is inserted into the engaging recess 10 of the wheel rim 9. Engage and install. At this time, since the protruding piece 2 is formed in an arc shape, it is difficult to bend the whole in the center direction, but the wheel cover 1 is changed in wall thickness to enhance the design, or the wheel cover 1 is changed from the brake drum. Since an opening (not shown) for discharging the radiant heat to the outside is formed, by deforming the wheel cover itself at these weak portions, the protrusion 2
Is inserted.

In the mounted state, the stopper 4 contacts the wheel rim 9 to prevent eccentricity of the wheel cover 1 due to vibrations and shocks caused by traveling of the automobile, and the retainer 6 reinforces the locking portion 3 to prevent the road wheel from moving. To prevent the falling off. 11 is a wheel disc of the road wheel.

[Problems to be solved by the invention]

However, in such a conventional wheel cover mounting structure, since the stopper 4 is integrally formed in a portion of the projecting piece 2 apart from the base portion 2a, when vibration or impact due to running of the vehicle is applied, Since the base 2a of the protruding piece 2 and the stopper 4 are flexibly deformed, the effect of preventing eccentricity of the wheel cover 1 is small.
Since the rotational force with the fulcrum as a fulcrum is applied, the locking portion 3 is disengaged and the wheel cover 1 is easily disengaged. Further, since the wheel cover itself is deformed to be attached to and detached from the wheel rim 9, a large force is required, and the wheel cover 1 can be easily deformed due to changes in the structure and design of the wheel cover 1. There was a problem that the holding power of was not constant.

This invention was made in order to solve the above problems, and it is possible to mount the wheel cover with a small force,
Stable holding force can be maintained without being affected by the structure and design of the wheel cover,
Accordingly, it is an object of the present invention to provide a wheel cover mounting structure capable of preventing the wheel cover from being eccentric due to vibration or impact force and preventing the wheel cover from falling off.

[Means for solving problems]

According to the invention, a plurality of projecting pieces integrally projecting on the back surface of the wheel cover, a flat plate-shaped portion formed on the base side of the projecting piece, and an arc-shaped portion formed on the tip side of the flat plate-shaped portion are provided. A notch formed on the base side of the projecting piece, a locking part projecting from the tip of the projecting part so as to engage with the engaging recess of the road wheel, and formed on the back surface of this locking part. Wheel cover having a recessed receiving portion, a retainer made of an annular wire rod that engages with the receiving portion, and a stopper protruding from the back surface of the wheel cover into the cutout portion so as to face the inside of the wheel rim. It is a mounting structure.

[Action]

In the mounting structure of the wheel cover of this invention, the retainer is engaged with the receiving portion of the wheel cover for mounting. Then, in this state, the protrusion of the wheel cover is bent and inserted into the road wheel, the engaging portion is engaged with the engaging concave portion and attached, and the stopper is opposed to the inside of the wheel rim. At this time, since the flat plate-shaped portion is formed on the base side of the projecting piece and the cutout portion is formed, the projecting piece itself flexes easily,
Can be inserted with a small force.

In the installed state, the stopper faces the inside of the wheel rim.Therefore, when vibration or shock is applied to the wheel cover while the vehicle is running, if the protrusion bends and the wheel cover tries to be eccentric, Contacts the wheel rim to prevent eccentricity of the wheel cover, which prevents the wheel cover from falling off. At this time, since the stopper is provided in the cutout portion independently of the projecting piece, there is a one-to-one correspondence with the projecting piece, and even if a force is applied to a particular projecting piece, its deformation Is prevented. Therefore, regardless of the structure and design of the design surface of the wheel cover, the holding property of the wheel cover is not affected and the stable holding force is maintained.

〔Example〕

Hereinafter, the present invention will be described based on embodiments of the drawings. FIG. 1 is a rear view of a wheel cover according to an embodiment of the present invention, FIG. 2 is a sectional view taken along the line BB, FIG. 3 is a view in the direction of arrow C in FIG. 1, and FIG. It is a figure, and the same code as Drawing 6 and Drawing 7 shows the same or equivalent portion.

The wheel cover 1 is made of elastic synthetic resin. The protruding piece 2, the locking portion 3 and the receiving portion 5 are formed in substantially the same manner as the conventional one, but the base portion 2a side of the protruding piece 2 is formed with a flat plate-shaped portion 2b having a linear cross section, and the tip thereof. An arcuate part 2c having a gradually increasing curvature is formed on the side, and the locking part 3
Is formed in an arc shape having a curvature corresponding to the locking recess 10 of the wheel rim 9. A notch 12 is formed in the center of the flat plate portion 2b, and a stopper 13 is provided at the notch 12. The stopper 13 is arranged so as to protrude from the back surface of the wheel cover 1 independently of the projecting piece 2 so as to face the radial direction, and to face the inner peripheral surface of the wheel rim 9. The stopper 13 may abut on the inside of the wheel rim 9 or may face each other with a slight gap.

In the wheel cover mounting structure configured as described above, the retainer 6 is attached by engaging the retainer 6 with the receiving portion 5 of the wheel cover 1. Then, in this state, the protrusion 2 of the wheel cover 1 is bent and inserted along the wheel rim 9 of the road wheel, and the engaging portion 3 is engaged with the engaging recess 10.
The stopper 13 is made to face the inner side of the wheel rim 9 by engaging with.

Since it is shorter, the flexibility of the protrusion 2 is good, and the wheel cover 1 can be easily attached.
The projecting piece 2 can be inserted with a small force without deforming. In the mounted state, since the stopper 13 faces the inside of the wheel rim 9, when the vehicle cover is vibrated or impacted by the traveling of the vehicle, the protrusion 2 is flexibly deformed and the wheel cover 1 is eccentric. If this is attempted, the stopper 13 comes into contact with the wheel rim 9 to prevent the wheel cover 1 from being eccentric, and thus the wheel cover 1
Is prevented from falling off. At this time, since the stopper 13 is provided in the cutout portion 12 independently of the projecting piece 2, the projecting piece 2
There is a one-to-one correspondence with respect to, and even when a force is applied to a specific projecting piece 2, its deformation is prevented. Therefore, regardless of the structure and design of the design surface of the wheel cover 1, the holding property of the wheel cover 1 is not affected and the stable holding force is maintained.

FIG. 5 is a perspective view of a part of another embodiment. In this embodiment, the cutout portions 12 are provided on both sides of the flat plate-like portion 2b, and two stoppers 13 are provided at the portions, so that the flexibility of the protrusion 2 and the eccentricity prevention effect of the wheel cover 1 are further enhanced. Become.

In the above description, the wheel cover 1, the protrusion 2,
The shapes of the locking portion 3, the receiving portion 5, the retainer 6, the stopper 13 and the like,
The structure and the like are not limited to those shown in the drawings, and can be changed.

[Effect of device]

According to this invention, the wheel cover is integrally formed with a protrusion having a flat plate-shaped portion, an arc-shaped portion, a locking portion and a cutout portion, and a stopper independent of this protrusion is made to face the wheel rim.
