Description

Drag Reduction Vehicles {AIR RESISTANCE DECREASE VEHICLES}

The present invention relates to a drag reduction vehicle, and more particularly, to a drag reduction vehicle provided with a drag reduction unit made of air inductions in a vehicle body to reduce a resistance to air during driving. .

The drag (air resistance) that the body receives when the vehicle travels does not significantly affect when the vehicle travels at low speeds, but increases in proportion to its speed when traveling at high speeds.

In addition, drag is increased due to resistance generated while the air flowing into the lower part of the vehicle collides inside the rear bumper.

However, according to the conventional vehicle, there is a problem in that the drag is transmitted to the vehicle body as it is when the vehicle is traveling (particularly, at high speed), and the running performance is significantly decreased.

Accordingly, an object of the present invention is to provide a drag reduction vehicle having a drag reduction portion made of air inductions in the vehicle body so as to reduce the resistance to air during driving of the vehicle.

The object is achieved by a drag reduction vehicle comprising a drag reduction portion formed in the vehicle body and consisting of air induction paths that reduce the resistance of the air to the vehicle body when the vehicle is running.

The air inflow path is disposed in both directions over the entire length of the upper body of the vehicle body, and extends to the entire length while passing through the front bumper, the A pillar, the B pillar, the C pillar, and the rear bumper of the vehicle body. It can be formed into a semicircle concave in view from the cross section.

The air flow path may be formed in a semi-circular shape recessed into the window frame of the vehicle as viewed in cross section.

The air induction path may be formed through the vehicle body at a position adjacent to the front and rear wheels of the vehicle.

In addition, the lower portion of the rear bumper may be formed as a net so as to significantly reduce the resistance when the air flowing into the underbody reaches the rear bumper when traveling at high speed.

Therefore, according to the drag reduction vehicle according to the present invention, the drag reduction portion made of the air induction in the vehicle body to reduce the resistance to the air during driving of the vehicle, the air resistance passing through the air induction to the vehicle body By applying pressure, buoyancy can be reduced to improve driving performance and safety.

Another effect of the present invention is to drive safely by blocking an external force during driving of the vehicle to prevent shaking.

Another effect of the present invention is to give elasticity to the vehicle body of the vehicle and to improve strength.

Another effect of the present invention is to reduce the overall weight of the vehicle.

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

1 is a perspective view showing a drag reduction vehicle according to the present invention, Figure 2 is a cutaway view showing a pillar portion of the drag reduction vehicle according to the present invention, Figure 3 is a drag reduction vehicle of the present invention Figure 4 is a partial perspective view showing a front wheel portion, Figure 4 is a partial perspective view showing a rear wheel portion of the drag reduction vehicle according to the invention, Figure 5 is a rear view of the drag reduction vehicle according to the invention 6 is a plan view of the drag reduction vehicle according to the present invention.

The drag reduction vehicle according to the present invention, as shown in Figure 1, is installed in the vehicle body (frame) of the vehicle 100, the air induction to reduce the resistance of the air to the vehicle body when the vehicle 100 is running It is configured to include a drag reducing unit 110 consisting of the furnace (110a, 110b, 110c, 110d).

As shown in FIG. 1, the air induction path 110a is formed to form a concave groove from the front bumper 120 side of the vehicle body via the rear bumper 121. The air induction path 110a passes through the front bumper 120, the A-pillar 122, the B-pillar 123, the C-pillar 124, and the rear bumper 121 of the vehicle 100. ) Is provided over the length. The air induction path 110a may be provided in various shapes such as a wave pattern that does not interfere with the flow of air in a direction in which air is delivered to the vehicle body.

As shown in FIG. 3, the air induction path 110b may be formed in the front wheel side vehicle body 104 in a position adjacent to the front wheel 107 of the vehicle 100. As such, the air induction path 110b provided on the front wheel 107 side of the vehicle 100 is formed to penetrate the vehicle body 104 at a position adjacent to the front wheel 107. The air induction path 110b serves to reduce the resistance of the air delivered to the front wheel 107 side of the vehicle 100.

As shown in FIG. 4, the air induction path 110c may be formed in the rear wheel side vehicle body 106 in a position adjacent to the rear wheel 108 of the vehicle 100. As such, the air induction path 110c provided on the rear wheel 108 side of the vehicle 100 is formed to penetrate the vehicle body 106 at a position adjacent to the rear wheel 108. This air induction path 110c serves to reduce the resistance of the air delivered to the rear wheel 108 side of the vehicle 100.

As shown in FIG. 1, the air induction path 110d may be formed in a half arc shape recessed into the window frame 102 side of the vehicle body. This air induction path 110d reduces the resistance of the air delivered to the window frame 102 side of the vehicle 100.

As shown in FIG. 5, the drag generated when the air introduced into the lower portion of the vehicle body collides with the rear bumper penetrates the net 125 formed at the lower portion of the rear bumper, thereby significantly reducing drag.

According to the drag reduction vehicle 100 according to the present invention having the above-described structure, the vehicle body-front bumper 120, A pillar 122, B pillar 123, C pillar 124, rear bumper 121, Air flow paths 110a, 110b, 110c, and 110d that reduce the resistance of air when the vehicle 100 travels to a predetermined portion of the window frame 102, the front wheel body 104 and the rear wheel body 106. By having a drag reduction unit 110 made of a), it is possible to improve the driving performance, to prevent shaking by blocking the external force applied to the vehicle 100, to give the elasticity to the vehicle body of the vehicle (100) In addition to improving the intensity, the overall weight of the vehicle 100 may be reduced.

While the exemplary embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to the specific embodiments, and those skilled in the art are appropriate within the scope described in the claims of the present invention. It will be possible to change it.
