DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wing movable rear spoiler for an automobile mounted on a rear portion of a vehicle body.

[0002]

2. Description of the Related Art A conventional wing movable rear spoiler is:
At the rear of the car body, on the tail that is opposite to the left and right or fixed at the center and fixed to the car body, a wing with a wing cross section that is long in the vehicle width direction, one at the top, or another position such as front and rear or up and down Each is mounted so that the angle of attachment to the tail can be changed.

[0003]

The conventional wing movable type rear spoiler has a wing mounting angle which is changed to reduce running resistance due to air rectification of the wing and increase running stability due to an increase in rear tire contact pressure during running. An improvement is obtained. However, when the wing is mounted at a high angle in the vertical direction during running at high speed, the contact pressure of the rear tire increases, but the running resistance increases due to the disturbance of the airflow behind the wing. Also, when the vehicle is running at a low speed, the rear tire contact pressure does not increase much even if the wing is mounted at a vertical angle. As a solution to this, there is an increase in the width of the wing in the front-rear direction of the vehicle body, an increase in the wing mounting angle change range, and the like.
Increased cost, disadvantage in strength and safety, restrictions on installation space,
Problems such as design restrictions arise. The present invention has been made to eliminate these disadvantages.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is mounted on a trunk lid panel, a back door panel, a roof panel and the like at the rear of a vehicle body. Hereinafter, embodiments mounted on a trunk lid panel will be described with reference to the drawings. 1 to 3 show a first embodiment. (A) FIG. 2 is a cross-sectional view showing the structure of the rear left portion of the vehicle body along the line AA in FIG. 1, and the structure on the right side opposed thereto is symmetrical to FIG. 2. Therefore, the structure will be described on the left side. (B) Tail 1 integrally molded with synthetic resin, metal, etc.
Are fixed to the trunk lid panel 2 with nuts 3. (C) A front wing side 5 is attached to a front wing 4 a of a wing cross-sectional shape that is long in the vehicle width direction with screws 6. (D) A rear wing side 8 is attached to a rear wing 7 a of a wing cross-sectional shape that is long in the vehicle width direction with a screw 6. (E) The rear wing side 8 is mounted on the front wing side 5 with the rear hinge bolt 9 and the rear adjustment bolt 10 so that the front of the rear wing 7 is arranged behind the front wing 4 with a slight gap. It is installed. When the left and right rear hinge bolts 9 and the left and right rear adjustment bolts 10 are loosened and the rear of the rear wing 7 is moved up and down using the left and right rear hinge bolts 9 as a rotation axis, the rear wing for the left and right tails 1 is obtained. 7
Is changed. The change range is limited by the right and left rear adjustment bolts 10 hitting the adjustment grooves 11 provided in the left and right rear wing sides 8. (F) The front wing side 5 of the component parts assembled according to the items (C) to (E) is fixed by the front hinge bolt 12 and the front adjustment bolt 13.
It is mounted on a nut of a bracket 14 embedded in the tail 1. When the left and right front hinge bolts 12 and the left and right front adjustment bolts 13 are loosened and the left and right front hinge bolts 12 are used as rotation axes and the rear parts of the components are moved up and down, the front wings 4 for the right and left tails 1 are removed. At the same time, the mounting angle of the rear wing 7 is changed. The range of the change is limited by the right and left front adjustment bolts 13 hitting the adjustment grooves 15 provided on the left and right front wing sides 5. (G) The front hinge bolt 12 may be pin-connected. 4 to 6 show the second embodiment, and the same structural parts as those in the first embodiment are denoted by the same reference numerals. (H) Since the left and right front wing sides 5 do not change the mounting angle using the left and right front hinge bolts 12 as the rotation axes as in the first embodiment, the structure and functions necessary for the angle change in the first embodiment are not shown. The structure and function of the front wing 4, the rear wing 7, the front wing side 5, and the rear wing side 8 other than these are unnecessary as in the case of the first embodiment. (1) Tail 1 integrally molded with synthetic resin, metal, etc.
Numeral 6 is fixed to the trunk lid panel 2 at the center of the rear of the vehicle body with a nut 3. (D) FIG. 5 is a cross-sectional view showing the structure on the right side of the tail 16 along the line CC in FIG. 4, and the structure on the opposite side of the tail 16 is the same as FIG. Therefore, regarding the structure, the right side will be described. A wing center 17 is mounted at the center of the front wing 4 with screws 18. (L) The wing center 17 of the component parts assembled according to the items (H) and (N) is a tail hinge 16 with a center hinge bolt 19 and a center adjustment bolt 20.
Mounted on the nut of the bracket 21 embedded in the bracket. When the left and right center hinge bolts 19 and the left and right center adjustment bolts 20 are loosened and the rear parts of the components are moved up and down with the left and right center hinge bolts 19 as a rotation axis, the front wing 4 with respect to the tail 16 is moved.
And the mounting angle of the rear wing 7 is changed integrally therewith. The range of the change is to adjust the left and right center adjust bolts 2 in the adjustment grooves 22 provided in the left and right
It is limited by hitting 0. (E) The center hinge bolt 19 may be pin-connected.

[0006]

The effects when the present invention is used will be described. (A) When the mounting angle of the front wing 4 and the rear wing 7 is adjusted to the position closest to the horizontal direction, the upper surfaces of both wings become one sheet. Since the upper surface of the large wing is formed, the running resistance is greatly reduced by the rectification of the wing during running. (B) If the mounting angle of the entire device is adjusted in the vertical direction from the state of (a), the rear wheel tire contact pressure increases while running resistance is low during running. This is suitable for increasing the contact pressure of the rear wheel tires during high-speed running to improve running stability. (C) When the rear wing 7 is adjusted in the vertical direction from the state of the item (a), the contact pressure of the rear wheel tire increases during the traveling compared with the item (b). However, running resistance also increases. Suitable for improving running stability by increasing the contact pressure of the rear wheel tires during middle-speed running. (D) Adjusting the mounting angle of the front wing 4 and the rear wing 7 to the position closest to the vertical direction, The increase in the contact pressure is the largest. This is suitable for increasing the contact pressure of the rear wheel tires at low speed running to improve running stability. (E) The running resistance and the rear tire contact pressure can be finely adjusted by any combination of the mounting angles of the front wing 4 and the rear wing 7.
