Abstract

PURPOSE:To make it possible to increase its effective area required only when high-speed running is performed, by mounting the main body of a rear spoiler on the upper face of the rear portion of a vehicle body, and providing the main body with a slide panel is such a manner that the panel can move backwards, in a vehicle equipped with the rear spoiler on the upper face of the rear portion to its body. CONSTITUTION:During low-speed running, a slide panel 9 is put back in the stepped portion 13 of the main body 8 of a spoiler so that the rear end of a rear spoiler 7 may not much protrude rearwardly from a vehicle body 5. When there is a need to use it during high-speed running, a motor 32 is then started to move while being rotated in the normal direction and the slide a panel 9 is pushed backwards via a driving gear 25 and via a wire 22. The slide panel 9 is thus forced to slide, via a guide roller 19, along a pair of right and left guide rails 20 at regular speed so that it is forced to protrude rearwardly from the main body 8 of the spoiler. The aerodynamic effective area of the whole body of the rear spoiler 7 is thus increased to obtain its sufficient effect.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a movable spear boiler for a vehicle.

(Prior Art) Some vehicles that travel at high speed are equipped with a rear spoiler 2 on the rear upper surface side of a vehicle body 1.

This type of spoiler 2 includes a fixed type spoiler fixed to the vehicle body 1 as shown in FIG. 28, and an arc-shaped guide member 3 provided on the vehicle body 1 as shown in FIG.
There is also a movable type in which the support arm 4 of the spoiler 2 is inserted vertically and slidably so that the front shadow projected area of the spoiler 2 increases when the spoiler 2 is raised.

(Problem to be Solved by the Invention) However, in the case of the former fixed type, in order to secure an aerodynamically effective area, the rear end of the spoiler 2 has to protrude further rearward than the vehicle body l. There is a drawback that the total length of the vehicle body 1 becomes longer by the amount of protrusion of 8.

In the case of the latter movable type, the spoiler 2 can be accommodated within the length of the vehicle body l, but the air resistance when the spoiler 2 is raised becomes extremely large, reducing fuel efficiency at maximum speed. At the same time, great rigidity is required, and it is also necessary to increase the driving force when ascending. Another disadvantage is that the visibility to the rear is also poor.

The present invention was provided for the purpose of solving such conventional problems.

(Means for Solving the Problem) As a means for solving the problem, the present invention provides a vehicle equipped with a rear spoiler 7 on the rear upper surface side of the vehicle body 5, in which a spoiler main body 8 is attached to the rear upper surface side of the vehicle body 5. A slide panel 9 is provided on the spoiler main body 8 so as to be able to move forward and backward.

(Function) During normal low-speed driving, the slide panel 9 is used as a spoiler.
Store it on the main body 8. Therefore, it does not protrude significantly rearward from the vehicle body 5, and the rear visibility does not deteriorate.

When driving at high speed, the slide panel 9 is slid rearward from the spoiler main body 8 to protrude. This increases the effective area of the rear spoiler 7 as a whole, but since the slide panel 9 is made to protrude rearward, the vehicle does not experience particularly large air resistance even when traveling at high speed.

(Example) The invention will now be described in detail with reference to the illustrated embodiments.

1 to 7 show a first embodiment of the present invention.

In FIG. 1, 5 is a vehicle body such as a passenger car, 6 is a trunk lid at the rear of the vehicle body 5, and 7 is a boiler attached to the upper surface of the trunk lid 6.

The rear spoiler 7 is composed of a spoiler main body 8 and a slide panel 9 provided on the spoiler main body 8 so as to be movable rearward. The spoiler main body 8 is hollow and has bent portions 10 bent diagonally downward at both left and right ends, and a pair of attachment portions 11 are provided near the inner side of the bent portions 10. As shown in FIG. 4, the mounting portion 11 is placed on the trunk lid 6 so that a predetermined gap is formed between the spoiler body 8 and the trunk lid 6, and is engaged with the edge 6a of the trunk lid 6. It is fixed with a matching retainer 12. As shown in FIGS. 2 and 3, the spoiler main body 8 is formed with a stepped portion 13 such that the rear half of the top side is lower than the front side, and the slide panel 9 is arranged on the stepped portion 13. has been done.

The slide panel 9 has a flat, hollow shape, and its upper surface is provided in a shape similar to the front upper surface of the spoiler body 8 and the road surface. As shown in FIG. The slide panel 9 is fitted so as to be movable in the direction shown in FIGS.
As shown in the figure, a bracket 18 is provided at a position closer to the center than both left and right ends, and a pair of front and rear guide rollers 19 pivotally connected to the bracket 18 are provided on the left and right, and each pair of guide rollers 19 is It is fitted into a pair of left and right guide rails 20 built into the spoiler main body 8 so as to be movable in the front and rear directions. Each guide rail 20 has a wire guide section 21.

2 is guided from the front end side of the wire guide section 22 through the guide pipe 24 to the drive gear 25 side, as shown in FIG. 7, and is pushed and pulled by the forward or reverse rotation of the drive gear 25. It has become. The drive gear 25 is
As shown in FIG. 2, the spoiler main body 8 is attached to an output shaft 31 of a reduction gear 30 at a storage portion 29 formed in the center thereof, and is operatively connected to an electric motor 32 via the reduction gear 31. The reducer 30 and the motor 32 are supported within the storage section 29 by a mounting base 33, etc., and the mounting base 33 is mounted inside the storage section 29.
The spoiler body 8 is assembled into the spoiler body 8 through the opening 34 on the lower surface side. 35 is a reinforcing plate for the slide panel 9.

In the above configuration, the slide panel 9 can move backwards and forwards along the guide rails 17 and 20 of the spoiler body 8, and can be retracted into the stepped portion 13 of the spoiler body 8 as shown by the solid line during low-speed driving. When driving at high speeds, it is used by protruding backwards as shown in the imaginary line.

That is, when driving at low speeds, if the slide panel 9 is retracted, it will fit within the front-to-back width of the spoiler body 8, so the rear end of the rear spoiler 7 will not protrude significantly from the rear of the vehicle body 5, and the front-to-back width will be reduced. Because it is small, it does not impede rear visibility. When it is necessary to use it for high-speed running, the motor 32 is started in the forward rotation direction and the drive gear 25 is
When the slide panel 9 is pushed rearward via the wire 22, the slide panel 9 slides rearward at a constant speed along the guide rail 17.20 and protrudes rearward from the spoiler body 8 as shown by the imaginary line. , the aerodynamically effective area of the entire rear spoiler 7 is increased, and sufficient effects can be obtained. In this case, since the slide panel 9 protrudes rearward,
The increase in air resistance is not much of a problem, so the slide panel 9 and its support mechanism are not required to have particularly high rigidity, and there is no need to increase the driving force. Of course, fuel efficiency does not become extremely bad at maximum speed.

As shown in FIG. 24, the wind pressure sensor 56 includes a sensing member 58 provided in a sensing hole 57 in the front part of the spoiler main body 8, a pair of left and right springs 59 that bias this forward, and a sensing member 58 that detects wind pressure. It consists of a mitt switch 60 that is turned on when it is moved backward against a spring 59. The spring 59 and limit switch 60 are housed in a recess 61 of the spoiler body 8. The limit switch 60 is
As shown in FIG. 25, it is connected to a relay circuit 62 that controls the motor 32 in forward and reverse directions. 63 is a power source.

In this way, the slide panel 9 automatically moves according to the traveling speed, eliminating the need for manual operation.

FIGS. 26 and 27 show a sixth embodiment of the present invention, in which the sensing pressure of a wind pressure sensor 56 can be adjusted. That is, the adjustment bolt 64 is inserted into the sensing member 58 so as to be rotatable in accordance with each spring 59.
A spring receiver 65 for receiving the spring 59 is screwed into the spring holder 65 . The spring receiver 65 is supported and guided by a rotation preventing projection 66 so that it cannot rotate. Therefore, when the adjustment bolt 64 is rotated, the spring receiver 6
5 moves and the pressure of the spring 59 changes, so it is possible to arbitrarily adjust and set the sensed pressure.

Although all of the embodiments have been illustrated using the electric motor 32 as the drive source, the drive source is not limited to this, and a hydraulic or pneumatic drive source may be used.

(Effects of the Invention) According to the present invention, the spoiler main body 8 is attached to the rear upper surface side of the vehicle body 5, and the slide panel 9 is provided on the spoiler main body 8 so that the slide panel 9 can move in and out rearward. The slide panel 9 only needs to protrude rearward from the spoiler body 8, and therefore does not always protrude rearward from the vehicle body 5 unlike the conventional fixed type. Furthermore, since the slide panel 9 moves rearward, it does not impair rear visibility unlike conventional movable models, and does not increase air resistance during running.
