Description

[Detailed Description of the Invention] The present invention relates to an air balance panel, and more particularly to an air balance panel that can move up and down to reduce air resistance that occurs when a car is running.

This type of air balance panel is attached to the body of an automobile in order to reduce air resistance that occurs when the automobile is running at high speed, thereby improving fuel efficiency.

For this reason, for example, as described in Japanese Patent Application Laid-Open No. 54-131219, in conventional devices, the air balance panel is rotatably supported on a shaft on the automobile body and rotated by a drive means. The air balance panel was made to move up and down relative to the car's body. As a result, when the air balance panel moves downward, air does not flow between the vehicle body and the road surface, reducing air resistance when the vehicle is running. On the other hand, in places where the car body is likely to swing and come close to the road surface, such as when driving on a defile, the air balance panel is moved upward to prevent it from interfering with the road surface.

However, in the above-mentioned conventional technology, the air balance panel is simply supported pivotally on the automobile body. As a result, air enters between the lower surface of the automobile body and the upper surface of the air balance panel, making it impossible to reliably and efficiently reduce air resistance.

Therefore, the technical problem of the present invention is to solve the problems of the prior art.

In order to solve this problem, the technical measures taken in this invention are to install parallel links in the air balance panel, which is attached to the front of the car body so that it can move up and down in order to reduce air resistance when the car is running. is vertically movably supported on the automobile body through the
The drive means causes the shift lever to move up and down in response to whether or not it is located in the high speed range, and
It is integrally formed with a resin bumper in a substantially U-shape from the front side of the body along the sides, and has a flexible part that can be freely expanded and contracted in the vertical direction of the body between the bumper and the bumper. However, the air balance panel is configured such that it is continuous with the bumper through the flexible portion without any gap. Moreover, a plurality of flange portions are formed on the flexible portion at predetermined intervals in the vertical direction and project approximately horizontally toward the outside of the body.

In this way, in the present invention, the air balance panel is integrally molded with a resin bumper, and a flexible part that can be freely expanded and contracted in the vertical direction of the automobile body is integrally provided between the air balance panel and the bumper. The flexible portion is connected to the front surface of the bumper without any gap.

Therefore, it is possible to prevent air from entering between the air balance panel and the road surface by moving the air balance panel downward by the driving means in accordance with the vehicle speed based on the position of the shift lever. Furthermore, no air enters between the bumper and the air balance panel when the vehicle is running, making it possible to reliably and efficiently reduce air resistance.

In particular, since the flange portion is formed to protrude horizontally from the flexible portion, it is possible to prevent the flexible portion from being bent significantly due to wind pressure, and its durability can be improved. Furthermore, the air is rectified by the flange portion, which improves the effect of reducing air resistance and prevents wind noise from occurring.

A preferred embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 10 denotes the body of an automobile, and a resin bumper 11 is attached to the front of the body 10 to absorb and soften the impact of a collision. 12 indicates an air balance panel;
The air balance panel 12 is integrally formed with the bumper 11 in a substantially U-shape along the body, and reduces air resistance that occurs when the vehicle is running at high speed. Furthermore, the front surface of the bumper 11 and the front surface of the air balance panel 12 are integrally formed so as to be continuous. Therefore, no air can enter between the automobile body 10 and the air balance panel 12.

The air balance panel 12 has a flexible portion 13 and can be expanded and contracted in the vertical direction of the automobile.

In FIG. 2, reference numeral 14 indicates a driving means such as a motor, and the driving means 14 is mounted in the body 10 of the automobile, and is functionally provided with an arm 15 that is extendable and retractable at one end. Reference numerals 16 and 17 indicate parallel links arranged within the air balance panel 12, and the end of the arm 15 is pivotally supported approximately at the center of one link 16. two links 16, 17
One end is pivotally supported on the vehicle body 10 side, and the other end is pivotally supported inside the lower end of the air balance panel 12, respectively. Thereby, the air balance panel 12 is supported by the automobile body 10 so as to be able to move up and down.

For example, as shown in Fig. 4, the switch 19 of the driving means 14 is turned on in response to whether the shift lever 18 is in the high-speed range or not. When the shift lever 18 is in the high-speed range, the arm 15 is extended by the driving of the driving means 14, pushing down the other ends of the links 16 and 17, and the flexible portion 13 of the air balance panel 12 is extended as shown in Figs. 2 and 3. As a result, the air balance panel 12 moves downward horizontally relative to the road surface as a whole. This prevents air from entering between the road surface and the automobile body, and reduces air resistance. When the shift lever 18 is moved to the low-speed range, the switch 19 is turned off, the arm 15 is contracted, and the air balance panel 12 moves upward.
As a result, the air balance panel 12 is accommodated under the bumper 11 (see FIG. 1).

Furthermore, bumper 11 and air balance panel 1
2 are integrally formed, the body 10
Air does not enter between the air balance panel 12 and the air balance panel 12, and air resistance can be reduced from this point as well.

As shown in FIG. 3, the flexible portion 13 described above is provided with a plurality of flanges projecting approximately horizontally outward from the body at predetermined intervals. to prevent excessive deformation due to
I'm trying to straighten the air.

As explained above, according to the present invention, the air balance panel is integrally molded with the resin bumper, a flexible portion is provided in the air balance panel, and the air balance panel is supported on the automobile body using parallel links so as to be movable up and down. ing. Furthermore, the air balance panel is moved up and down by the driving means according to the vehicle speed.

Therefore, it is possible to prevent the air balance panel from moving downward and causing air to enter between the air balance panel and the road surface. Moreover, no air can enter between the bumper and the air balance panel,
Air resistance can be reduced reliably and efficiently.

Moreover, since the air balance panel is formed integrally with the bumper, the configuration is extremely simple.
Furthermore, there is an advantage that the manufacturing cost is low.

Furthermore, since the air balance panel is supported by parallel links, not only its front portion moves up and down, but the entire air balance panel moves up and down horizontally with respect to the road surface. Therefore, when the air balance panel moves downward, its entire lower surface comes into contact with the road surface. Therefore, even if the air balance panel is moved down to the same height from the road surface, the amount of air that enters between the air balance panel and the road surface can be reduced compared to when the air balance panel is rotated. From this point of view,
It also means that air resistance can be reduced compared to conventional devices. In particular, since the air balance panel has a substantially U-shape, it is possible to prevent air from entering from the sides as well as the front of the body, which significantly reduces air resistance.
