DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a rear spoiler device for a vehicle such as a passenger car in which a spoiler can be raised and lowered.

(Prior Art) In a rear spoiler device of a vehicle, a spoiler is mainly arranged in the upper rear part of a trunk lid, and a plurality of arcuate elevating members in the left-right direction are fixed to the lower surface side of the spoiler. The guide member for guiding is fixed to the trunk lid, and the lifting member is configured to be moved up and down via a power transmission member such as a cable pushed and pulled by a driving device also fixed to the trunk lid. [For example, JP-A-62-2
47984 Specification and Drawing (Priority Claim Application)].

(Problems to be Solved by the Invention) In the above-mentioned prior art, since the drive device is fixed to the trunk lid together with the elevating member and the like and has a relatively large weight, the opening and closing of the trunk lid becomes heavy, so that the trunk lid is opened and closed. The springs need to be changed to strong ones, the space in the luggage compartment is narrowed, and the degree of freedom in the layout of the drive device is low.

(Means for Solving the Problem) In the present invention, the drive device is attached to the vehicle body main body side to reduce the weight of the cover body, and the drive device is extended to the elevating member side below the front end of the cover body. It is an object of the present invention to provide a rear spoiler device for a vehicle, which can solve the above-mentioned problems of the prior art by using a flexible power transmission member.

The specific configuration of the present invention for achieving this object is that a cover body forming a rear portion of a vehicle body is pivotably supported at a front end so that the rear portion can be opened and closed, and a spoiler is arranged at an upper rear portion of the cover body.
A plurality of arcuate elevating members in the left-right direction are fixed to the lower surface side of this spoiler, and a guide body for guiding each elevating member is provided on the cover body side, and all elevating members are simultaneously moved to the guide body via power transmission means. In a rear spoiler device for a vehicle having a drive device for raising and lowering, the drive device is attached to a vehicle body main body side that pivotally supports a cover body, and a power transmission means passes from the drive device to a lower portion of a front end of the cover body. The point is that the flexible power transmission member is extended to the side.

(Operation) In FIGS. 1 to 4, when the motor 24 of the drive unit 7 is operated, one flexible cable 25b is pushed and the relay member 29 connected to the tip slides in the case 30. . One end of each of the three flexible cables 15b is connected to the relay member 29, and each other end thereof is connected to the elevating member 5.
Sliding of the relay member 29 is simultaneously transmitted to all the elevating members 5 and pushes it up. All elevating members 5 ascend within the guide body 6 to raise the spoiler 4 fixed to their upper ends. The drive device 7 is not attached to the trunk lid 3, but is fixed to the vehicle body 2 side.
The weight of the trunk lid 3 is light and the power is transmitted from the drive device 7 to the lifting member 5 side by the flexible power transmission means 25, so that the trunk lid 3 can be freely opened and closed.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

1 to 4, reference numeral 1 denotes a rear spoiler device provided on a rear upper portion of a passenger car, and a trunk lid 3 (PR) as a cover body forming a rear upper portion of a vehicle body body 2.
The spoiler 4 is placed on the hood of the car.
The front end of the trunk lid 3 is pivotally supported on the body body 2 side via a pivot support 9.

The rear spoiler device 1 includes the spoiler 4, three elevating members 5 fixed to the lower surface thereof, a guide body 6 for guiding each elevating member 5, a driving device 7, and a driving force of the driving device 7. Power transmission means 8 for transmitting to

The spoiler 4 is a movable air guide member which is formed in a plate shape elongated in the left-right direction and has a solid or hollow inside, and three (or more) spoilers 4 are mounted on the lower surface of the spoiler 4 via a bracket (not shown) or the like. The lifting member 5 is screwed.

The elevating member 5 is a solid or hollow member having a circular or rectangular cross-section, the outer shape of which is formed in an arc shape, and a pin 11 is planted in the lower portion.

The guide body 6 has a split shape, and an arcuate cylindrical hole 12 having the same curvature as that of the elevating member 5 is formed in order to guide the elevating member 5 so that the elevating member 5 can be moved up and down, and is fixed to the back surface of the trunk lid 3. Has been done. The upper part of the elevating member 5 projects upward from the guide body 6 and the trunk lid 3. The elevating member 5 and the guide body 6 form a spoiler elevating part 13.

A cable guide is provided on the lower side (outer peripheral side) of the guide body 6.
14 is formed, the end portion of the outer tube 15a of the power transmission member 15 is fixed to the cable guide portion 14, and the end portion of the inner cable 15b is movably inserted. A long groove 18 in the arc direction is formed in the intermediate wall 17 between the cylindrical hole 12 of the guide body 6 and the inner cable guide groove 16.
The pin 11 of the elevating member 5 is inserted into the pin 18, the pin 11 is engaged with the engaging member 19 at the end of the inner cable 15b, and the elevating member 5 is driven up and down by the movement of the inner cable 15b.

The drive unit 7 is attached to the body 2 other than the trunk lid 3, and the rack 22 and the pinion are installed in the casing 21.
And a motor 24 (including a speed reducer) that drives the pinion 23 are attached to the casing 21. The outer tube 25a of the power transmission member 25 is fixed to the casing 21, and the inner cable 25b thereof is engaged and connected to the rack 22, and the rotation of the pinion 23 by the motor 24 causes the inner cable 25b to pass through the rack 22. Push-pull operation is performed. Reference numeral 26 is a micro switch housed in the casing 21 and detects the moving end of the rack 22 (the rising position or the falling position of the spoiler 4).

The power transmission means 8 between the drive device 7 and the elevating / lowering member 5 has the three power transmission members 15, one power transmission member 25, and a relay portion 28 connecting them.

The relay member 29 of the relay portion 28 is slidably accommodated in the casing 30, one end side of which is connected with the ends of the three inner cables 15b of the power transmission member 15, and the other end side thereof. The inner cable 15b of the power transmission member 25 is engaged and coupled, and the outer tube 15 of each flexible power transmission member 15, 25 is connected.
The a and 25a are locked to the case 30. The power transmission member 25 is passed through the lower portion of the front end of the trunk lid 3 which is pivotally supported, with a slack.

Therefore, when the inner cable 25b is pushed and pulled by the movement of the rack 22, the three inner cables 15b are pushed and pulled at the same time via the relay member 29, and the three lifting members 5 are simultaneously driven up and down by the same amount. The spoiler 4 is steplessly moved up and down from the retracted position (the lower position shown by the solid line in FIG. 4) in close contact with the trunk lid 3 to the working position (the raised position shown by the dashed line in FIG. 4) that guides the air. Further, regardless of the position of the spoiler 4, when the trunk lid 3 is opened or closed, the power transmission member 25 is flexibly deformed.

It is preferable to use screw cables for the power transmission members 15 and 25, but any other flexible material such as a push-pull wire may be used. Since it is to connect the relay section 28 attached to the trunk lid 3 to be used, it is preferable to use one having flexibility and durability.

FIG. 5 shows a first modified example of the drive unit 7, in which the motor
A fan gear 32 is meshed with a pinion 23 attached to the output shaft of 24, and one end of an inner cable 25b of a power transmission member 25 is pin-connected to the fan gear 32. Push and pull 25b.

When 34 operates to push (or pull) iron core 34a, lever 36 is swung to push (or pull) inner cable 25b, and the spoiler is raised. The returning operation of the iron core 34a is performed by a spring.

The assembly consisting of the lifting member 5 and the guide body 6 is 2
One set or four or more sets may be provided. In that case, the relay member 29
The number of power transmission members 15 connected to is the same as that of the assembly. Although it is possible to connect four or more inner wires 15b to the relay member 29 shown in FIG. 3, there is a possibility that the push-pull force may be uneven.

FIG. 7 shows the relay portion 28 in which the pushing and pulling force applied to the four inner wires 15b is made more uniform. The relay member 29 'has a substantially four-leaf clover shape, the inner cable 25b is connected to the center, the inner cable 15b is connected to the four leaves via a caulking member, and the four-leaf shape relay member 29' is slidable. Tube mounting plates 38 and 39 are screwed with a guide case 37 inserted between them, and one outer tube 25a is attached to the tube mounting plate 38 and 4 to the tube mounting plate 39.
The outer tubes 15a of the book are attached respectively, and the pushing / pulling action of the inner cable 25b is transmitted to the inner cables 15b connected at equal distances from the outer tube 15a in substantially the same size, and the relay member 29 'is twisted against the guide case 37. No, it is slid smoothly.

The present invention is not limited to the above embodiment, but can be modified in various ways. For example, the power transmission member 15,25
