By using , you can get the following effects: Generally, when driving at high speeds in the rain, the wipers lift up, reducing the ability to wipe the windshield, and furthermore, the point at which the washer fluid lands on the windshield changes significantly, a phenomenon that significantly impairs the driver's forward visibility. Therefore, as shown in FIG. 3, in the movable air spoiler for a vehicle according to the present invention, the direction of the airflow flowing on the bonnet 50 is forcibly shifted upward by the bonnet 5, thereby reducing the influence of the airflow on the wiper and washer liquid. be able to. On the other hand, during normal driving,
By holding the main body movable part 20 at a low position, the driver's forward visibility is secured.

The results of experiments conducted by the present inventors regarding the effect of improving the aerodynamic characteristics are shown in No. 10-. ΔCD,
ΔC and ΔC respectively indicate the ratios to co and ct when the vehicle movable air spoiler is not attached to the rear end of the trunk lid. However, CD is the drag coefficient and C is the lift coefficient. According to this, the minimum value of ΔCD is -3% at a height of 60 m.
, ΔC is -21%, which is a large reduction effect in CD%CL.

Rear visibility is almost guaranteed. Therefore, when the movable air spoiler for a vehicle according to the present invention is attached to the rear end of the trunk lid, the main body movable part 20 is raised to a height of about 60 m during high-speed driving, improving aerodynamic characteristics, and during normal driving. The main body movable part 20 is lowered to a height of about 20 m to ensure rearward visibility.

動部２０を下降させることになる。The movable air spoiler for a vehicle according to the present invention actively utilizes the positive pressure or negative pressure generated around the vehicle body while driving, guides it to the airtight chamber 30, raises the main body movable part 20,
However, the inventors conducted experiments to determine how much pressure could be obtained from around the vehicle body while it was running, and the 9th
The results shown in the figure were obtained. In the graph of Figure 9, positive pressure was led from the front grill of the vehicle, and negative pressure was led from inside the engine compartment. Fl is the force that pushes the main body movable section 20 from inside due to positive pressure, F2 is the force that pulls the main body movable section 20 from the inside due to negative pressure, and F3 is the force that pushes the main body movable section 20 from the inside due to the surface pressure generated on the surface of the main body movable section 20 while driving. It shows the force that pulls the movable part 20 from the outside. In addition, the main body movable part 20 in this experiment had a weight of 0.5 kg and a pressure receiving area (both the front and back surfaces) of 0.5 kg.
1n? And so. According to this, when the main body movable part 20 is raised, for example, when the vehicle is traveling at a speed of 1100 km/h, a force of 3 kg is applied to the back surface of the main body through the airtight chamber 30 due to positive pressure. At the same time, the main body movable part 2
-0.3k+r on the 0 surface due to the surface pressure, that is, 0
．． A lifting force of 3 kg is applied, and in addition to the force due to positive pressure, a force of 3.3 kg is applied to the main body movable portion 20.
will increase. Conversely, when the main body movable part 20 is lowered, when the vehicle is traveling at a speed of 1100 k/l), -1 kg, that is, 1 kg of the main body movable part A force acts in the direction of lowering 20. at the same time,
-0.3k on the surface of the main body movable part 20 due to surface pressure
g, that is, a lifting force of 0.3 kg also acts,
Including the force due to the negative pressure, the main body movable portion 20 is lowered with a force of 0.7 kg.
また、正圧、負圧が共にゼロの場合でも、車速か２５ｋ
ｍ／ｈ以上であれば、前記本体可動部２０の表面圧だけ
で、前記本体可動部２０重量以上の力が得られることも
わかった。Also, even if both positive pressure and negative pressure are zero, the vehicle speed is 25kph.
m/h or more, it was also found that a force greater than the weight of the main body movable part 20 can be obtained just by the surface pressure of the main body movable part 20.

In this embodiment, when this air spoiler is attached to the bonnet, the input for elevation angle adjustment is used as the vehicle running condition, and in addition to the signal from the vehicle speed sensor, the raindrop detection sensor 61 is used, and only when these vehicle running conditions fall within the set range, the electromagnetic Valves 43B and 43G are operated. This makes it possible to automatically change the elevation angle without the driver checking for rain and turning on the wiper switch each time. In addition, when the air spoiler of this embodiment is attached to the trunk lid, the manual switch 4OA operated by the driver is omitted and only the signal from the vehicle speed sensor 60 is input as the vehicle running condition, so that the driver can operate the manual switch. Elevation angle can be changed automatically without turning it on or off.
