Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wheel cover for a vehicle that opens and closes a radiating hole of a wheel cover body by weight weight operated by centrifugal force generated when the wheel of the vehicle rotates.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

Conventional patent documents for preventing the air conditioner from lowering the fuel consumption of the vehicle by generating air resistance during running due to heat dissipation holes for cooling the brake heat are known.

The retractable automobile wheel cover disclosed in Patent Document 1 is a structure for opening and closing the wheel cover by using an electromagnet, which is complicated in the arrangement and mounting of the electromagnet, and it is difficult to supply electricity to the rotating component.

In addition, when the brake is operated, the vehicle is likely to be injured when the pedestrian is close to the vehicle by being opened and protruding in the vehicle lateral direction.

In the wheel cover vent hole opening / closing apparatus of Patent Document 2, the structure in which the piston moves back and forth by the pressure of the brake is not easy to transmit pressure to the piston mounted on the rotating wheel, The structure is complex.

The spoke wheel having the aerodynamic improvement structure of Patent Document 3 is an open / close structure using a cylinder having an air passage. Inside the rotating wheel, the inner cover is operated by the air entering from the outside through the passageway in a state where the flow of air is already active And the size of the air passage is limited, so that the amount of air supplied to the inside may be insufficient, and the air introduced into the air passage itself interferes with the rotation of the wheel.

Further, since the inside of the wheel spokes is opened and closed, the outside of the wheel spokes causing the reduction of the aerodynamic force is not covered and its effectiveness is low.

These conventional patent documents 1, 2, and 3 collectively receive energy from the outside and operate the wheel cover, so that the structure is complicated and the cost is high and the feasibility is very low.

The vehicle wheel cover according to Claim 3 of the present invention is characterized in that the cam portion comprises a ramp formed on the opening and closing plate and a sliding shaft provided on the other end of the bar and sliding along the ramp, And the other end is supported by the sliding shaft.

In the wheel cover for a vehicle according to claim 4 of the present invention, an elastic clip is further provided on a rear surface of the wheel cover body to be inserted into the vehicle wheel.

The present invention has the following effects.

Since the radiating hole is closed by using the centrifugal force generated when the vehicle wheel rotates, supply energy for closing is not required.

Further, since no additional supply energy is required for closing, the structure is simple, the cost is low, and the weight of the vehicle can be more effectively reduced.

There is an opening / closing device in the inside of the wheel cover main body, so that air resistance is not received.

By providing an opening / closing device inside the wheel cover body, it is possible to exchange various design products on one wheel.

Particularly, since a clip to be inserted into the wheel is provided on the rear surface of the wheel cover main body, the bolt fastening hole formed in the hub of the wheel cover main body is eliminated, so that there is no influence of air resistance when the bolt fastening hole is present.

1 and 2, the vehicle wheel cover 10 according to the present embodiment includes a wheel cover body 30 mounted so as to cover the vehicle wheel 1 from the outside, And a clipping device 60 disposed inside the wheel cover body 30 for opening and closing the heat dissipation hole 37.

The wheel cover main body 30 is formed of a plurality of arms 35 connecting the hub 31 and the rim 33 and the hub 31 and the rim 33. The wheel cover main body 30 has a through hole 37, And a cover made of a plastic material.

A hub shaft 32 is formed on the rear surface of the hub 31. [

As shown in FIG. 2, the hub shaft 32 is composed of three split shafts, which are retracted when the support plate is inserted, and then restored.

The hub shaft 32 is formed on the outer circumferential surface with a fitting protrusion 32a on the front and rear sides to prevent the support plate 61 from being rotatably fitted between the front and rear fitting protrusions 32a.

The wheel cover body 30 is mounted on the vehicle wheel 1 so that the discharge hole 37 faces the air hole 3 of the vehicle wheel 1. [

The vent hole 3 is a through-hole formed between the spokes 5 of the vehicle wheel 1, to radiate and cool the heat generated in the brake.

The opening and closing device 60 includes a support plate 61 rotatably supported on the hub shaft 32, an opening and closing plate 63 formed around the support plate 61 and opening and closing the heat dissipating hole 37, A spring 65 for applying elasticity to the opening and closing plate 63 in the direction of opening the opening 37 and an operation member 67 for closing the opening 37 by rotating the opening and closing plate 63.

The support plate 61 may be a hollow disk and may be fitted in the hub shaft 32.

It is also preferable that a bearing or a bush is interposed between the support plate 61 and the hub shaft 32 to smoothly rotate the support plate 61 while stably supporting the hub shaft 32.

The opening and closing plate 63 is formed by the number of openings and closings of the air discharge hole 37 along the outer periphery of the support plate 61.

The wheel cover body 30 is preferably formed with a stopper 64 for limiting the maximum closing angle of the opening / closing plate 63 (see FIGS. 2 and 4).

It is preferable that a torsion spring 65 for applying an opening force to the opening / closing plate 63 is applied to the spring 65.

The operation member 67 is operated when the centrifugal force due to the rotation of the vehicle wheel 1 is larger than the restoring force of the torsion spring 65. [

That is, the operation member 67 includes a bar 71 installed on the arm 35 with a hinge 69 at the center side, a weight 73 provided at one end of the bar 71, And a cam portion 75 for opening and closing the opening / closing plate 63 by raising and lowering the other end with respect to the rotation of the other end.

The bar 71 is in the shape of a bar and the hinge 69 is supported at the center of the bar 71.

The weight 73 is provided at one end which is the upper end of the bar 71.

When the centrifugal force is greater than the restoring force (during running), the weight 73 moves clockwise in the clockwise direction along the centrifugal force so that the bar 71 is rotated in the clockwise direction to close the vent hole 37 4).

When the restoring force is larger than the centrifugal force (when braking), the weight of the weight 73 is overcome, and one end of the bar 71 is rotated counterclockwise to open the discharge hole 37 (see FIG.

The cam portion 75 is composed of a ramp 77 formed on the opening and closing plate 63 and a sliding shaft 79 provided on the other end of the bar 71 and sliding along the ramp 77.

The ramp 77 is embodied as an elongated hole or groove having an inclined angle with respect to the turning radius.

The sliding shaft 79 is slidably mounted in the ramp 77.

One end of the torsion spring 65 is supported by the protrusion 66 of the fixed wheel cover main body 30 and the other end of the torsion spring 65 is supported by the movable bar 71, .

As described above, in this embodiment, the amount of rotation of the opening / closing plate 63 is also generated in accordance with the centrifugal force of the vehicle wheel 1. [

On the other hand, an elastic clip 90 to be inserted into the vehicle wheel 1 may be further provided on the rear surface of the wheel cover main body 30. [

The elastic clip 90 is inserted into the insertion hole 7 formed in the spokes 5 of the vehicle wheel 1.

5 and 7, the elastic clip 90 is a steel clip 90 fixed to the bracket 80 formed on the back surface of the wheel cover main body 30. As shown in Fig.

The steel clip 90 includes a pair of elastic locking pins 91 formed on the upper and lower sides or the left and right sides, a C-type connecting plate 93 connecting the other ends of the elastic locking pins 91, and a C- And a support bracket 95 supported by the bracket 80 while being supported by the inner surface of the bracket 80.

The elastic locking pin 91 is of a cantilever type including a first extension pin 91a and a second extension pin 91b extending from the C-type coupling plate 93. [

The first extension pin 91a is gradually inclined upwardly toward the second extension pin 91b and the second extension pin 91b is inclined downward again so that when inserted into the insertion hole 7, When the pin 91a is inserted, when it is pushed downward and then passed over to the second extension pin 91b, it is caught by the latching jaw 9 while being lifted up by elasticity.

Due to the configuration of the elastic locking pin 91 and the insertion hole 7, a hole for bolting is not required in the wheel cover 10, and the aerodynamic force can be further improved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. It will be apparent to those skilled in the art.
