Description

[Detailed description of the invention] [Industrial application field] The present invention is attached to the outer surface of the vehicle body of a vehicle such as an automobile to improve aerodynamic characteristics. The present invention relates to a vehicle air spoiler device that improves the contact between the tires and the ground by reducing the lift force of the vehicle.

[Conventional technology]

Among the conventional air spoiler devices of this type, there is one that is capable of adjusting the elevation angle of a spoiler plate that deflects airflow, as disclosed in, for example, Japanese Patent Laid-Open No. 60-234076.

As shown in FIG. 10 (FIG. 10 is a copy of FIG. 2 in the above publication), this conventional device has a support member 02 fixed to the top surface of a trunk lid 01 of an automobile. The front end of the flat spoiler plate 03 that is long in the left and right direction is connected to an axis 04 that faces in the left and right direction.
A sector gear 05 having an arc shape centered on the shaft 04 is vertically attached to the lower center of the rear end of the spoiler plate 03, and a worm 06 that meshes with the sector gear 05 is provided on the trunk lid 01. By rotating the motor 07,
The spoiler plate 03 is rotated around an axis 04.

According to this conventional device, by adjusting the elevation angle of the spoiler plate according to the traveling speed of the vehicle,
This has the advantage of always maintaining optimal aerodynamic performance.

[Problem that the invention attempts to solve]

In the air spoiler device in which the elevation angle of the spoiler plate 03 can be adjusted as described above, in order to improve aerodynamic performance, it is preferable to widen the adjustable range of the elevation angle of the spoiler plate 03; In order to do this, for example, in the conventional device described above, the sector gear 05 must be lengthened downward, and in this case, the sector gear 05 must be inserted into the trunk lid 01, or the entire device must be made taller. There is a problem that it must be done.

In addition, like the conventional device described above, the air spoiler device attached to the trunk lid 01 is required to be small and lightweight in order not to interfere with the opening and closing of the trunk lid 01, and the air spoiler device is required to be small and lightweight. The amount of overhang, which is the amount of protrusion from the top, is regulated by safety standards, so there is a demand for thinner products.

An object of the present invention is to solve the above-mentioned problems and to provide a vehicle air spoiler device that satisfies the above-mentioned demands.

[Means for solving problems]

The vehicle air spoiler device of the present invention is a specific means for solving the above-mentioned problems.The spoiler plate is pivotably attached to the vehicle body with the base end having an axis pointing in the left-right direction. One end of each of a plurality of inclined links, which are inclined in opposite directions, is connected to the central part and both sides, respectively, with a shaft pointing in the left-right direction, and the other end of each inclined link is connected to a guide fixed to the vehicle body. Each of the sliding bodies is connected to a sliding body slidably attached to the device in the longitudinal direction, and at least one of the central sliding body and the sliding body on both sides is reciprocated by a drive device provided on the vehicle body. As a result, the tilted links are raised and lowered in opposite directions to rotate the spoiler plate.

[Effect]

In the vehicle air spoiler device of the present invention,
Under normal conditions, the spoiler plate is stopped at a position that is approximately parallel to the surface of the vehicle body, and when the vehicle is to be driven at high speed, or when the vehicle is traveling at high speed, the drive device is activated.
Only one sliding body is moved in a predetermined direction along the guide device.

Then, one of the inclined links stands up, the end of the spoiler plate on the inclined link side is lifted, and the spoiler plate rotates upward around the pivot point to the vehicle body.

This upward rotation of the spoiler plate causes the other inclined link to rise in the opposite direction to the rising direction of one inclined link, and furthermore, the sliding body connected to the other inclined link is
It is driven in the opposite direction to one sliding body.

When the spoiler plate reaches a desired or predetermined angle of inclination, the actuation of the drive device is stopped;
The movement of one sliding body and one inclined link is stopped, and the spoiler plate is stopped at that position. When the spoiler plate stops, the movement of the other sliding body and the other inclined link also stops.

By operating the drive device in the opposite direction to that described above, the spoiler plate can be returned to its original position.

The spoiler plate may be configured to be able to stop in only two positions: a substantially horizontal non-use position and a use position at a predetermined angle of inclination, or it may also be able to stop in a desired intermediate position. Good too.

As mentioned above, when only one sliding body is forcibly moved by the drive device, the other sliding body and the other inclined link are driven as the spoiler plate rotates, and the spoiler plate rotates. It acts as a guide.

However, when both sliding bodies are forcibly moved at the same time by a drive device, the other sliding body and the other inclined link are not limited to the guiding action of the spoiler plate as described above; In cooperation with one of the inclined links, it functions to rotate the spoiler plate stably and reliably.

There is almost no possibility that it will invade the sliding portion between the guide device 37 and the guide device 46.

Therefore, smooth operation can be maintained and durability can be improved.

In the outer cover 60, rainwater that has accumulated on the upper surface of the trunk lid 12 is drained from the gap between the upper surface of the trunk lid 12 and the lower edge of the outer cover 60, or from a drainage hole (not shown) formed as necessary. ) etc., and is discharged to the outside of the outer cover 60.

In addition, a sealing member (not shown) such as a rubber plate with a slit cut therein is appropriately installed in each of the long holes 61 and 62, and the support plates 24 and 25 in each of the long holes 61 and 62 are
It is also preferable to close the gap other than the inclined link 39.

As shown in FIGS. 1, 8, and 9, the left and right side guide mechanisms 16 (as they have the same structure, only one will be described below) are connected to the central rotation mechanism 15. identical components,
It has different component parts.

First, the same components as the central rotation mechanism 15 will be described. The side guide mechanism 16 includes upwardly facing protrusions 64 and 65 at the front and rear ends, and a pair of front and rear legs 66 and 67. It also includes a base member 68 secured onto the trunk lid 12.

A projecting piece 70 having an inclined slightly arcuate elongated hole 69 is connected to both intermediate sides of the base member 68, and this projecting piece 70 is provided with support plates 71 and 72 that sandwich it from the left and right, and support plates 71 and 72 that sandwich it from the left and right, and A pivot support device 75 consisting of a bolt 73 and a nut 74 passing through the elongated hole 69 is attached.

A pivot 77 that pivots the front end of the mounting plate 76 fixed to the lower surface of the spoiler plate 14 by the upper end of the
It is supported so that its position can be adjusted.

If the pivot shaft 31 in the central rotation mechanism 15 and the pivot shafts 77 in the left and right side guide mechanisms 16 are not completely aligned, the rotation of the spoiler plate 14 may be hindered or the rotation may be interrupted. Since this is impossible, each pivot support device 32, 75 is a position adjustment means for positioning each pivot 31, 77 so perfectly in line.

Next, to explain the difference from the configuration of the central rotation mechanism 15, in the center of each of the front and rear projecting pieces 64, 65 of the base member 68, each end of one horizontal guide pin 78 facing the front and rear direction is provided. The parts are fixed.

A sliding body 80 having a through hole 79 through which the guide pin 78 passes is mounted on the guide pin 78 so as to be slidable in the front-rear direction.

At the center of the lower surface of the sliding body 80, there is a long rectangular hole 82 formed in the center of the base member 68 and long in the front-rear direction.
A hanging piece 81 that extends downwardly through the base member 68 is connected to the left and right side surfaces of the hanging piece 81, and a cylindrical part 83 that passes below the base member 68 and extends to both sides is connected to the left and right sides of the hanging piece 81. ing.

A lower end of an inclined link 84 is pivotally attached to the tip of each cylindrical portion 83 with a shaft 85 parallel to the pivot 77 . Both inclined links 84 are integrally connected to each other near their upper ends by connecting rods 86 facing in the lateral direction, and have a generally H-shaped planar shape as a whole.

This inclined link 84 is located on the opposite side of the central rotation mechanism 15 from the inclined direction of the inclined link 39.
That is, it is inclined rearward and upward, and its upper end is pivotally attached to the rear end of the mounting plate 76 with a shaft 87 parallel to the pivot 77 .

This shaft 87 is the shaft 4 in the central rotation mechanism 15.
There is no particular need to arrange it in a straight line with 2, and
The length of the inclined link 84 does not need to match the length of the inclined link 39 in the central rotation mechanism 15. In the embodiment, the inclined link 84 is connected to the inclined link 3.
It is slightly longer than 9.

A compression coil spring 88 is compressed between the rear surface of the sliding body 80 and the rear projection piece 65 of the base member 68 so as to be wound around the guide pin 78. As a result, the sliding body 80 is always urged forward.

The sliding body 80, as shown by the solid line in FIG.
The front end position where the hanging piece 81 contacts the stopper 90 made of rubber or the like fitted to the hanging piece 89 hanging from the front edge of the elongated hole 82, and the hanging piece 81 as shown in phantom lines in FIG. 81 is a stopper 92 made of rubber or the like fitted to a hanging piece 91 hanging from the rear edge of the elongated hole 82.
It is possible to move between the rear limit position where it is in contact with the

When the spoiler plate 14 is maintained at the unused position by the central rotation mechanism 15, the sliding body 80 is held at the front end position by the biasing force of the compression coil spring 88, and the inclined link 84 is moved as shown in FIG. As shown by the solid line in , the spoiler plate 14 is supported at both rear sides thereof so as not to vibrate vertically unintentionally with the upper part tilted most backward.

The spoiler plate 14 is rotated upward to the use position by the central rotation mechanism 15, that is, by pulling the cable 53 and erecting the inclined link 39 against the biasing force of the compression coil spring 48. In this case, along with this upward rotation of the spoiler plate 14, the upper end of the inclined link 84 is pulled up, the inclined link 84 is made to stand up as shown by the imaginary line in FIG. 8, and the sliding body 80 is It is moved to the rear limit position against the biasing force of the compression coil spring 88.

When the central rotation mechanism 15 moves the spoiler plate 14 from the use position to the non-use position, the biasing force of the compression coil spring 88 assists the spoiler plate 14 in the direction of lying down.

In this way, the left and right side guide mechanisms 16
When the spoiler plate 14 is rotated around the pivots 31 and 77 by the central rotation mechanism 15,
Guide the both sides of the spoiler plate 14, and
Make the rotation of 4 smooth.

Of the above-described configurations, the base member 68, guide pin 78, stoppers 90, 92, etc.
A guide device 93 is formed that guides 0 in a reciprocating manner in the front and back direction.

94 is an inner cover similar to the inner cover 58 of the central rotation mechanism 15, and 95 is an outer cover similar to the outer cover 60.

Next, the overall operation of the apparatus of this embodiment will be briefly explained.

When the spoiler plate 14 is in the horizontal non-use position, the sliding body 37 is positioned at the rear limit position by the biasing force of the compression coil spring 48, and the sliding body 8
0 is positioned at the forward limit position by the biasing force of the compression coil spring 88, and the inclined link 39 is moved forward.
Further, the inclined links 84 support the spoiler plate 14 in a state in which they are respectively laid down rearward.

From this state, when the motor 51 of the drive device 17 is activated to rotate the winding drum 50 clockwise in FIG. Force and compression coil springs 88 in the side guide mechanism 16
(This urging force is also applied to the sliding body 3 via the inclined link 84, spoiler plate 14, inclined link 39, etc.)
7), the inclined link 39 stands up, and the rear end of the spoiler plate 14 is rotated upward about the pivots 31, 77.

Along with this, the upper end of the inclined link 84 in each side guide mechanism 16 is pulled up, so that the inclined link 84 is erected, and its lower end and the sliding body 80 resist the biasing force of the compression coil spring 88. and be moved backwards.

When the sliding body 37 reaches the front limit position, the inclined link 39 is in an upright position, and the spoiler plate 14 is in the use position. At this time, the inclined link 84 stops in an inclined state in which the lower end is located slightly forward of the upper end,
Furthermore, the sliding body 80 stops at the rear limit position.

In this way, when the car runs at high speed while the spoiler plate 14 is maintained in the use position, the spoiler plate 14 tilts upward at the rear.
The wind pressure acting on the top surface generates a force that pushes the rear of the vehicle downward, and this force pushes the tires against the ground against the wind-induced lift when the vehicle is running at high speeds, improving the tire's ground contact. do.

When the spoiler plate 14 is in the use position, the motor 51 is operated to rotate the winding drum 50 in the counterclockwise direction in FIG.
3 is unwound from the winding drum 50, the sliding body 37 is moved rearward by the biasing force of the compression coil spring 48, and the sliding body 80 is moved forward by the compression coil spring 88, and the inclined link 39 The tilting links 84 are gradually lowered in opposite directions, and the spoiler plate 14 is lowered so that the angle of elevation becomes gradually smaller, and returned to its original unused position.

Note that the spoiler plate 14 can also be stopped at a position halfway between the use position and the non-use position by stopping the operation of the motor 51.

In the present invention, among the above embodiments, the spoiler plate 1
4, that is, the spoiler plate 14 and the inclined link 3 in the above-mentioned embodiment.
9. The basic structure consisting of the sliding body 37, the guide device 46, and the drive device 17 includes an inclined link 84 that raises and lowers in the opposite direction to the raising and lowering direction of the inclined link 39, and a slide that moves in the opposite direction to the sliding member 37. Regarding the configuration in which the configuration of the side guide mechanism 16 is added to guide the rotation of the spoiler plate 14 by the moving body 80, this configuration can produce the effects described later as an effect of the invention.

[Modified example]

In the present invention, the following changes and modifications are possible, for example.

(1) In the above embodiment, each side guide mechanism 1
The sliding body 80 in 6 is linked to the drive device 17 by, for example, a cable 53 and another cable (not shown), and this sliding body 80 is synchronized with the sliding body 37 in the central rotation mechanism 15, By actively moving the spoiler plate 14 in opposite directions, the spoiler plate 14 is driven at three locations: the center and both sides.

(2) Only the sliding body 80 in the side guide mechanism 16 is linked to the drive device 17, and the central rotation mechanism 15 side is used only to guide the rotation of the spoiler plate 14.

(3) In the drive device 17, for example, a pinion rotated by a motor is engaged with a rack fixed to the side surface of the sliding body 37, and the pinion is rotated by the motor to move the rack and the sliding body 37 in a desired direction. A structure other than the above-mentioned embodiment is used.

(4) The vehicle air spoiler device 13 is attached to the vehicle body 11 at a location other than the trunk lid 12, for example, the roof of the vehicle body 11 or the like.

[Effect of idea]

According to the present invention, when the elevation angle of the spoiler plate is small, both inclined links are collapsed, so the distance between the spoiler plate and the vehicle body surface can be significantly reduced, and the entire device can be made thinner. In addition, by increasing the length of both inclined links, the angle of elevation of the spoiler plate can be made as large as desired.Moreover, even if the length of the inclined links is large, the spoiler plate and the vehicle body surface when it is collapsed. The advantage is that the distance between the two does not change much.

Therefore, according to the present invention, it is possible to contribute to miniaturization of the entire device, particularly to reduction in thickness.

Further, according to the present invention, with at least one pair of inclined links that raise and lower in opposite directions,
Since the spoiler plate is rotated and guided,
The spoiler plate can rotate stably and smoothly.

Further, according to the present invention, since the tilted link is pivotally connected to the spoiler plate with an axis parallel to the pivot of the spoiler plate, the tilted link The wind pressure can be absorbed by the inclination of the roof and the back and forth movement of the sliding member, and the direction in which the tilting link can be tilted is the front and back direction in which the spoiler plate receives wind pressure, so the spoiler plate can be strongly supported against wind pressure. I can do it.
