Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an air spoiler structure for a vehicle.

(Prior Art) An air spoiler rectifies the flow of air near the vehicle body when the vehicle is running, and in particular, when the vehicle is traveling at high speeds, it lifts the vehicle body down by using lift due to air resistance and air flow to prevent the body from rising. It is for doing.

FIG. 5 shows an air spoiler in which a wing-shaped straightening plate mounted in the vehicle width direction is used in the rear part of the vehicle body. The wing 3 is fixed on the top. At high speed, the sub-wing 4 further projects obliquely upward from the wing 3 to increase the force (down force) for pressing the vehicle body downward.

FIG. 6 shows a wing type rear spoiler different from the one described above. Normally, as shown by the chain double-dashed line in the figure, the stay 5 and the wing 6 are housed in the rear body as they are, and the stay 5 5 and the wing 6 are raised.

(Problems to be solved by the invention) However, the air spoiler having the structure shown in FIG. 5 does not look good when the sub-wing 4 is operated, and when the sub-wing 4 is housed in the wing 3, the hands are caught. There is a defect of. Further, in the air spoiler having the structure shown in FIG. 6, since the wing cannot be seen from the outside when it is housed in the vehicle body, it is not possible to sufficiently exhibit a high-class appearance due to the wing attached.

The present invention has been made in order to solve the above-mentioned conventional problems, and it is possible to obtain sufficient downforce at high speed, at the same time, to operate safely, and to sufficiently exhibit a high-class appearance. An object of the present invention is to provide an air spoiler structure for a vehicle.

(Means for Solving the Problems) In order to achieve the above object, according to the present invention, a rectifying plate that extends in the vehicle width direction and is attached to a rear portion of a vehicle through a stay is provided, and the vicinity of the vehicle body when the vehicle is traveling In a vehicle air spoiler structure for rectifying the air flow of the vehicle by the rectifying plate, a guided object that is integrally provided on the lower surface of the rectifying plate and has an arc-shaped lower surface that extends in the front-rear direction of the vehicle and is convex downward A member, a guide that is provided at the tip of the stay, engages with the guided member, and guides the guided member slidably in the longitudinal direction of the vehicle; and a guide provided along the lower surface of the guided member. A rack extending in the front-rear direction of the vehicle, and provided in the stay in mesh with the rack,
A pinion is provided, which is rotated by a motor according to a vehicle speed to move the guided member together with the straightening plate in the front-rear direction of the vehicle while being guided by the guide.

(Operation) During high-speed running, the gear rotates by the motor, and if this gear is used as a pinion, the rail part, which is so to speak a rack, moves to the rear of the vehicle body, and as a result, the straightening vane integrally with the rail moves to the rear of the vehicle body. The downforce increases remarkably. On the other hand, during normal traveling, the rail is returned to its original position by rotating the motor in the opposite direction.

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

As an example, FIG. 1 shows a case in which the present invention is applied to a wing type rear spoiler. The rear body 12 of a vehicle 11 has, for example, three stays 13 at appropriate intervals along the vehicle width direction.
~ 15 are fixed, and a wing 16 which is a current plate is attached to these stays 13-15.

2 and 3 show details of the mounting structure of the wing 16 and the stay 14, for example, and the wing 16 is formed into a substantially streamlined wing shape in cross section, as shown in FIG. A downwardly convex arcuate rail member (guided member) 17 is attached to the wing 16 integrally with the lower surface thereof. As shown in FIG. 3, the rail member 17 is formed to have a substantially E-shaped cross section, and gear teeth (rack) 18 are formed on the lower surface 17a thereof. On the other hand, the upper edge 14a of the stay 14 is formed in an arc shape having substantially the same curvature as the rail member 17 described above, and a guide member (guide) 19 also formed in an arc shape is fixed to the upper opening. . A recess 17b of the rail member 17 is slidably fitted in the center of the guide member 19.

A gear (pinion) 20 that meshes with the gear teeth 18 of the rail member 17 is provided inside the stay 14, and the gear 20 is connected to a gear 22 that rotates integrally with a rotating shaft 21 of a motor (not shown).

 The operation will be described below.

During normal traveling, the wing 16 is in the position shown in FIG. 2, and during high speed traveling, the rotary shaft 21 and the gear 22 of the motor rotate counterclockwise, and the gear 20 rotates accordingly. Gear teeth 18 of rail member 17 of wing 16 and this gear
Speaking of 20, there is a rack and pinion relationship, and the rail member moves to the right, that is, toward the rear of the vehicle body 11 as shown by the alternate long and short dash line in FIG. 4 as the gear 20 rotates. Therefore, the wing 16 protruding obliquely upward from the rear end of the stay 14
The amount of protrusion at the rear end is increased, giving a larger downforce to the vehicle body, which enables stable running at high speed.

When returning from the above-mentioned high-speed traveling to the normal traveling again, the rotary shaft 21 of the motor rotates in the opposite direction, that is, in the clockwise direction, and the rail member 17 moves leftward in FIG. Return to the position indicated by the solid line.

Such a sliding operation of the wing 16 may be carried out by a switch provided on the inner panel of the driving vehicle as needed, and is automatically carried out, for example, when the vehicle speed exceeds a predetermined value. May be set as follows. In the case of automatic operation, it is possible to set the amount of protrusion of the rear end of the wing 16 to continuously change depending on the vehicle speed.

In the above embodiment, the case where the stay 14 is provided with the slide mechanism of the wing 16 is described, but the present invention is not limited to this. For example, the stays 13 and 15 at both ends may be provided with the slide mechanism described above. .

As described above, according to the present invention, the straightening plate that extends in the vehicle width direction and is attached to the rear portion of the vehicle through the stay is provided to straighten the air flow near the vehicle body when the vehicle is running. In an air spoiler structure of a vehicle that is rectified by a plate, the guided member is provided integrally with the lower surface of the rectifying plate and has an arcuate lower surface that extends in the front-rear direction of the vehicle and is convex downward, and is provided at the tip of the stay. Is engaged with the guided member,
A guide for slidably guiding the guided member in the front-rear direction of the vehicle, a rack provided along the lower surface of the guided member, extending in the front-rear direction of the vehicle, and provided in the stay in mesh with the rack, Since it is rotated according to the vehicle speed, the pinion that moves the guided member together with the current plate in the front-rear direction of the vehicle while being guided by the guide is provided. It is possible to improve the running stability of the vehicle body by sliding the vehicle toward the rear of the vehicle body, the operation stability of the rectifying plate is good, and moreover, it is possible to sufficiently exhibit a high-class appearance. Have the advantage of.
