rear spoiler

Abstract

To provide a car that reduces air resistance of the vehicle and improves fuel efficiency. [Solution] Car C has a natural intake port at the front of the vehicle that discharges airflow to the rear of the vehicle, and also has elongated oval recesses at the bottom of both sides of the vehicle that swirl and generate airflow at the rear.

Description

[Technical Field]

[0001] This device is a part that aims to improve high-speed stability and fuel economy by attaching walls R5 and L5 (Fig. 5) to the bottom of the lower end of the rear spoiler body 30 (Fig. 5), and attaching walls R5 and L5 to the vehicle body at the upper rear of the vehicle (Fig. 1). [Background technology]

[0002] Conventional rear spoilers are wing-like parts attached to the upper rear of a car to improve driving stability. These rear spoilers emphasize design and do not have any particular functionality. Summary of the Invention [Problem to be solved by the invention]

[0003] This invention was not only designed to be functional, but also to have a good design. Specifically, it was not possible to control the airflow stably at high speeds while the car was moving. Also, the rear spoiler was not able to improve fuel efficiency. In addition, the purpose of the invention is to provide a recess on the side of the car C to generate vortices WPL and WPR (Fig. 1 and Fig. 2) on the side, and to achieve high-speed stability by adding them to the spoiler toward the rear of the car.

[0004] The means for solving the problem is to direct the air (airflow) 100 (Fig. 3) received from the front of a moving vehicle toward the rear of the rear spoiler 10 as airflows BW and UBW. The rear spoiler 10 (Fig. 5) is configured with a rear spoiler body 30 and walls R5 and L5 attached to both ends of the bottom surface of the rear spoiler, so that the airflow BW flows toward the rear of the vehicle C (Fig. 5).

[0005] Then, a recess is provided in the lower part of the side of car C to receive the airflows FW, LW, and RW (Fig. 1) that come from the front of car C. The airflows RW and LW from the front create vortices WPL and WPR in the recess on the side of car C.

[0006] In this invention, when the car C receives airflow from the front FW, 100, UBW (Fig. 3) and sides RW, LW (Fig. 1), the rear spoiler 10 moves rearward of the car C, allowing the car C to travel stably. In addition, by the same effect, the airflows RW and LW received from the side also cause vortices WPL and WPR generated in the depressions on the side to flow backward of car C, allowing car C to travel stably. Furthermore, it allows for stable high-speed driving, which improves fuel efficiency. [Brief explanation of the drawings]

[0008] 1 and 2, airflows FW, LW, and RW hit the front of car C. Airflow FW hits the front grille of car C. Airflow 100 hits the windshield of car C. Airflow 100 enters through the opening of rear spoiler 10 and is discharged to the rear BW, UBW of vehicle C (Figure 1). The frontal airflows LW, RW at the sides of vehicle C generate vortices WPL, WPR in the depressions on the sides of the vehicle, enabling stable high-speed driving (Figures 1 and 2).

[0009] In FIG. 3, airflow FW hits the front grille of car C at the front. Airflows SR and SL flow on the sides. Airflow 100 hits the windshield. Airflow BW passes through the gap between walls L5 and R5 of rear spoiler 10.

[0010] In Figure 4, as in Figure 3, the airflow passes through BW, SL, SR, and UBW.

[0011] 5 and 6 are perspective views of the rear spoiler 10. The rear spoiler 10 is composed of a main body 30 and walls R5 and L5. An airflow BW flows from the front to the rear between the walls R5 and L5.

[0012] 7 and 8 are a front view and a rear view of the rear spoiler 10. The rear spoiler 10 is composed of a main body 30 and walls R5 and L5. The airflow passes between the walls and exits through the BW passage.

[0013] 9 and 10 are a plan view and a bottom view of the rear spoiler 10. The rear spoiler 10 is composed of a main body 30 of the rear spoiler 10 and walls L5 and R5. The main body of the rear spoiler 10 has a rectangular shape. Airflow BW passes through the cavity of the rear spoiler 10 from the front portion to the rear portion BW (FIGS. 9 and 10).

[0014] 11 and 12, Fig. 11 is a right side view, and the tip of the rear part of the main body is shaped like a mountain to reduce air resistance. The configuration of the spoiler 10 is the same as Fig. 9 and Fig. 10. Fig. 12 is a left side view of the spoiler 10, and is the same as Fig. 11.

[0015] 13 shows a rear spoiler 11 according to a second embodiment. The configuration is the same as that of the rear spoiler 10, with a rounded main body 31 and walls L6 and R6. The effect is an airflow BW2 that flows from the front to the rear, similar to that of the rear spoiler 10 according to the first embodiment.

[0016] 14 shows the rear spoiler 12 of Example 3. The rear spoiler 12A is an elongated rectangular component with walls R7 and L7 connected together. The spoiler 12B is an elongated triangular component, and the spoiler components 12A and 12B are connected by a connecting component to form an H shape. The effect is composed of three parts: first, in the center, airflow 100 from the front of car C passes through rear spoiler 12A and hits the triangular wall of spoiler 12B, holding down the rear of car C with air to prevent car C from floating. In the front right part of spoiler 12, airflow passes through cavity 12A and hits the wall of triangular member 12B, and airflow 100 flows above and below as airflow BW3R. Similarly, in the front left portion of the spoiler 12, the airflow passes through the cavity 12B and hits the wall of the triangular member 12B, and the airflow 100 flows above and below as the airflow BW3L.

[0017] As such, the above-described embodiments are merely illustrative in all respects and should not be construed as limiting. Furthermore, all forms and modifications within the scope of the equivalents of the utility model registration claims are within the scope of the present invention. [Industrial Applicability]
