PURPOSE:To enable selective use of a wind guide board as a rear spoiler or a device for preventing a rear glass from getting dirty by rotatably fixing a wind guide board which is placed at the upper rear part of an automobile body, extended in the direction of its width, and making it remotely turnable from inside an automobile. CONSTITUTION:When a control lever is shifted from a neutral position to a spoiler position to pull a geared wire 28, while driving at a high speed, a link 16 which has a gear 18 meshed to the wire 28 is rotated counter-clockwise to a position where it engages with a stopper 23. Then the rotating power is transmitted to a link 19, pinion 21, sector gear 22, and a wind guide 10 is rotated to a position S where a spoiler is actuated. In this condition, the wind is pointed in the direction (a) and ground contact force of rear wheels is increased. On the other hand, when driving in rain, the control lever is rotated to a position of deflector and the geared wire 28 is shifted to the right, the wind guide board 10 is rotated to a wiping position D, and a part of the wind is directed to the direction (b) and raindrops etc on the surface of rear glass 5 are wiped off.

Description

[Detailed description of the invention] Separation for Au on p1 chamber This book is my own! 11 Concerning the rear part of the rickshaw.

In the case of conventional automobiles, for example, as shown in Japanese Utility Model Application Publication No. 13939/1983, rear visibility is improved by blowing off raindrops, splashes, dust, etc. adhering to the bank door glass and rear window glass. In order to ensure this, it is known that a tatami-style sheet metal is installed on the upper rear side of the vehicle body so that the wind flowing along the roof panel is directed in one direction so that it flows along the back door glass and rear window glass surface. ing. This will be explained in detail by taking a car f:1+l+ equipped with a back door as shown in FIGS. is a wind guide plate arranged in the vehicle width direction on the rear finished side of the vehicle body, specifically, on the upper side of the door frame 4. , this 0 leg ff1
17 is fixed to the back door frame 4. This baffle plate 6 is arranged approximately parallel to the back door 2, and
Its upper end protrudes slightly above the surface of the roof panel 3, and captures a portion of the wind that flows along the roof panel 3 when driving and deflects it along the surface of the back door glass. It has a wiping effect that blows away raindrops, splash, dust, etc. that adhere to the door glass.
This is to ensure sufficient rear visibility for the occupants.

However, with such a conventional structure, while the wind guide plate 6 can provide the function of wiping away drops, splash, etc. from the back door glass, a lifting force is generated at the rear of the vehicle body as it deflects the running wind diagonally downward, especially at high speeds. When the vehicle is running, this tendency becomes unsightly, resulting in a problem that worsens the running stability.

Purpose of the Invention In view of the conventional situation, the present invention not only allows the surface of the back door glass and rear window glass to be wiped away by the driving wind when driving in the rain, but also increases the ground contact force of the rear wheels when driving in non-rainy weather. To provide a rear wind guide system R for an automobile that can function as a rear spoiler that reduces the resistance value and allows the function change operation of the wind guide plate to be operated while remaining in the passenger compartment. It is something.

I am trying to encourage you.

Next, the operation of the embodiment device having the above-mentioned groove end will be briefly explained.

II When driving at high speeds even in the rain or in the rain,
When the operating lever 26 is rotated from the neutral position N to the spoiler position S shown in FIG. 5, the guard wire 2B is pulled and the link 16 is rotated counterclockwise until it engages with the stopper 23. The rotation of this link 16 in the counter-chronological direction is supported by the link 19. Binion 21 f Kf: is transmitted to the sector gear 22 h, so that the baffle plate 10 rotates (~stops) at the casing action position St. Therefore,
The wind flowing backward along the roof panel 3 is directed diagonally toward the upper blade as shown by the arrow a in Figure 4 by the guide plate 1 (), and the 1.1 child 1 is lost, and the 10 is blown away by the wind. Increases the strength of the fρ wheels and stabilizes runningkk
It can be used as a capstone, and it can also be used as a nitrogen resistance value. Note that the 1:☆ operation bar 26 and one end of the Bowden cable 27 are connected with play, and when you release your hand from the operation 1/bar 26, only the operation lever 26 is moved by the biasing force of a spring (not shown). The vehicle returns to the neutral position N, so that the operating lever 26 does not become a room when getting on and off (-).

11] When the operating lever 26 is rotated from the neutral position iii N to the deflector position ■], the guard wire 28 is moved to the 1st position and the link 16 is fully stopped 24.
Rotate clockwise with the lever that engages, this time! The help is transmitted to the sector gear 22i' through the link 19° and the pinion 21, and the windshield 10 is rotated at the wiping action position Di (...
? ;To stop it.

Accordingly, the total amount of the driving wind flowing at Yθ on the three surfaces of the roof panel is captured by the baffle plate 10 and is directed diagonally downward along the bank door glass five surface as indicated by the arrow 34. The raindrops and splashes that adhere to the five back door glass surfaces can be blown away to keep them clean.
This ensures rearward visibility for the occupants.

When driving at medium or low speeds in urban areas, the wind guide plate 10 can be rotated to the wiping action body f&D even when the windshield is 11#.

(If you set it to 9t, you can completely avoid dust from adhering to the back door glass 5.

Here, the baffle plate 10 is placed at the spoiler action position 1. tS
.

Even if the wiping action position is in the opposite position, the link [
Since the axis IAO of the link 19 and the axis O7 of the link 19 are substantially perpendicular to each other, the following advantages can be obtained. 6. When the plate 10 is in the spoiler action position S, the wind guiding plate 10 is caused by the traveling wind to generate the IIP pressure P in the clockwise direction in FIG.
, (i-received. This pressing force P acts as a biasing force in the counterclockwise direction in the figure on the link 19 via the sector gear 22 and pinion 21, but this biasing force acts on the link 16 in the direction of the axis O1, and No single rotational moment acts on the link 16.On the other hand, when the air guide plate 10 is in the wiping action position, contrary to the above, the fourth air plate 10 is moved in the counterclockwise HF direction.
Pressure Pf acts on the link 19 as a biasing force in the dark direction. However, in this case as well, the biasing force P acts on the link 16 in the direction uhio, causing a rotational moment to act on the link 16. As a result, the wind guide plate 1
0 is the spoiler action value 1ifS, the wipe action position 1fD
In either case, the rotating mechanism 12 does not move due to the wind pressure while the vehicle is running, and the set position of the air guide plate 10 can be completely determined. Also, link 16 and link 19
The link 17 is connected to the link 17 via the guide slit 20, and the movement of the link 19 in the vicinity of the starting and stopping positions is decelerated, so that the operation is very smooth.
