The specific embodiment
Below, with reference to accompanying drawing embodiments of the present invention are described.
Fig. 1 is the synoptic map of guiding device of the present invention.The left side of figure is direct of travel, becomes vehicle front side.Guiding device 10 of the present invention has: spoiler 11, and it is located at the lower surface of vehicle 50, and is installed on S. A. 15 in the mode that can rotate; With the torsion spring 20 as application of force unit, it is so that the mode application of force that this spoiler 11 rotates to vehicle front side (in Fig. 1 around cw).In addition, will be made as tilt angle theta in the angle that forms between the planar portions of wind of travelling of being subject to towards the horizon of vehicle front side and spoiler 11.
When stopping or during low speed driving, spoiler 11 becomes the state of closing, and the angle of inclination with respect to vehicle front side of the spoiler 11 of this moment becomes θ
1On the other hand, when running at high speed, spoiler 11 bears the wind-force W from the wind that travels of vehicle front, if it is stronger than the application force of torsion spring 20 that this wind-force W becomes, then spoiler 11 becomes large direction (in Fig. 1 around conter clockwise) and rotates to the angle of inclination, when spoiler 11 is opened maximum, become tilt angle theta such shown in the dotted line among the figure
2By spoiler 11 being opened, can be reduced the amount of air that flow between vehicle 50 and the road surface 40, the result can realize the reduction of aerodynamic drag factor (CD value).Below, the structure of guiding device 10 is at length described.
Fig. 2 is the block diagram that the embodiment of guiding device of the present invention is shown, and (a) is when stopping or the state during low speed driving, (b) is the state when running at high speed.In addition, Fig. 3 is the lateral plan that the embodiment of guiding device of the present invention is shown, and (a) is when stopping or the state during low speed driving, (b) is the state when running at high speed.
Vehicle side installing component 12 and spoiler installation portion 11b are installed on S. A. 15 in the mode that can rotate respectively, but, vehicle side installing component 12 is fixed in the lower surface of vehicle 50 via fixed parts 12', the result becomes spoiler 11 to be installed into the state that can rotate with respect to vehicle 50.In addition, because the direction of S. A. 15 is transverse direction of vehicle 50, therefore, can rotate to the fore-and-aft direction of vehicle 50 although spoiler 11 is installed into, slewing area is by retainer 11b2 described later or rake 11b1 restriction.
About the torsion spring 20 as application of force unit, S. A. 15 runs through the center that is wound into the screw-shaped spring, one end of torsion spring 20 is fixed in spoiler 11(spoiler installation portion 11b), the other end of torsion spring 20 is fixed in vehicle side installing component 12.And, this torsion spring 20 is so that the mode application of force that spoiler 11 rotates to vehicle front side (cw of Fig. 3), therefore, when the wind-force W from the wind that travels of vehicle front surpassed the directed force F of torsion spring 20, spoiler 11 rotated to becoming large direction with respect to the tilt angle theta towards the direction of vehicle front side.
Shown in Fig. 3 (a), when stopping or during low speed driving, spoiler 11 is because the directed force F of torsion spring 20 and closed to the place ahead direction of vehicle 50, but, it is not the position that is closed to the lower surface that is accommodated in vehicle 50, but closed with the state that is keeping tilt angle theta 1, in order to can open during wind travelling of the intensity of being expected.In the present embodiment, constitute: 11b is provided with rake 11b1 at the spoiler installation portion, by this rake 11b1 and vehicle side installing component 12 butts, even under the state of Fig. 2 of spoiler 11 closures (a), Fig. 3 (a), also can keep the tilt angle theta 1 of spoiler 11.
Angle of inclination when in addition, needing in advance spoiler 11 to be opened maximum is defined as desirable angle θ
2Shown in Fig. 2 (b), Fig. 3 (b), make desirable angle θ
2Basically be preferably 90 °.This is because can think: in the time of 90 °, it is maximum that the overhang of spoiler 11 becomes, thereby can reduce the lower surface that flow into vehicle 50 and the amount of air between the road surface 40.
In order to reach desirable angle θ
2In time, limit rotation, sets in advance retainer 11b2 and get final product.In the present embodiment, constitute: the retainer 11b2 of convex is set, when spoiler 11 reaches desirable angle θ at spoiler installation portion 11b
2The time, this retainer 11b2 is connected to vehicle side installing component 12.And, opening to desirable angle θ
2State under, if the wind-force W of the wind that travels is larger than the directed force F of torsion spring 20, then stay open.
At this, in the guiding device that spoiler 60 is opened to the rear side of vehicle 50 as the patent documentation 2 of formerly enumerating, because spoiler 60 is traveling the rear side pushing of wind direction vehicle 50, so the angle of inclination can not become 90 °.In addition, in the situation of the deflecting plate that does not rotate, if the angle of inclination of spoiler is fixed as 90 °, then spoiler obstacle easy and on the road surface contacts, and therefore can't increase overhang.
On the other hand, in the situation that guiding device 10 of the present invention, spoiler can turn to tilt angle theta by means of the wind that travels becomes namely 90 ° of desirable angles, in addition, owing to being the structure of only when running at high speed, rotating, therefore, even increase overhang, the probability that spoiler 11 and obstacle etc. contact is also lower.Therefore, can effectively reduce air resistance.
In addition, in the guiding device 10 shown in Fig. 1～3, so although because spoiler 11 probability that only obstacle outstanding and on the road surface contacts when running at high speed is lower, but still may occur that stone splashes or spoiler is run into the such situation of unexpected obstacle.Therefore, though will possess when contacting with obstacle spoiler also the guiding device of non-damageable structure be described below as the 2nd embodiment.
Fig. 4 is the block diagram that the 2nd embodiment of guiding device of the present invention is shown, (a) be when stopping or the state during low speed driving, (b) be state when running at high speed, (c) be the state of obstacle and spoiler collision, Fig. 5 is the lateral plan that the 2nd embodiment of guiding device is shown, (a) being when stopping or the state during low speed driving, (b) is the state when running at high speed, and (c) is the state that obstacle and spoiler collide.In addition, Fig. 6 is the block diagram of observing the 2nd embodiment of guiding device from rear side.
About the guiding device 100 shown in the 2nd embodiment, as Fig. 4 (b), Fig. 5 (b), reach desirable angle θ at spoiler 11
2In time, rotates and temporarily to be limited, and then, in the situation that spoiler 11 and obstacle 30 come in contact etc., such as described below, spoiler 11 can turn to desirable angle θ as Fig. 5 (c)
2Above.
Vehicle side installing component 12 or fixed parts 12', S. A. 15 similarly are located at vehicle with aforesaid embodiment.About the spoiler 11 that is installed on S. A. 15, can make board 11a and spoiler installation portion 11b as one, also can be used as different parts.In addition, the tilt angle theta when spoiler 11 reaches desirable angle θ
2The time, retainer 13 and vehicle side installing component 12 butts, this is also same with aforesaid embodiment., in the guiding device 100 of the 2nd embodiment, make retainer 13 and spoiler 11 form the parts that separate.
The retainer 13 of the 2nd embodiment contacts with the 11b3 of crown section of spoiler installation portion 11b, and the retainer 13 of the 2nd embodiment is installed on S. A. 15 in the mode that can rotate.And retainer 13 is connected with spoiler via being configured to be rotated the torsion spring 21 that axle 15 runs through and is connected.That is, there are following two kinds in torsion spring: below the torsion spring 20(, as " the 1st torsion spring "), it is so that the mode application of force that spoiler 11 rotates to vehicle front side; Below torsion spring 21(, as " the 2nd torsion spring "), it is located between retainer 13 and the spoiler 11.
And, constituting, spoiler 11 turns to integratedly spoiler 11 with retainer 13 and reaches desirable angle θ
2Till.And constitute, when spoiler 11 is run into obstacle 30 and so that spoiler 11 reaches the tilt angle theta more than the desirable angle
3The time, retainer 13 with the state of vehicle side installing component 12 butts under motionless, only have spoiler 11 to rotate.Specifically, the shape of the rear view of vehicle side by making the 11b3 of crown section forms circular-arc centered by S. A. 15, thus, rotates while spoiler 11 can contact with respect to retainer 13.And, in tilt angle theta
3The time, spoiler 11 by the 2nd torsion spring 21 towards desirable angle θ
2The application of force, therefore, when clearing the jumps 30 the time, spoiler 11 returns to desirable angle θ
2In addition, when being θ 3 at the angle of inclination, the directed force F of torsion spring 20 also continuingly acts on spoiler 11, therefore, says exactly, and spoiler 11 is subject to two directed force F, F2 simultaneously.
When the parking shown in Fig. 4 (a), Fig. 5 (a) or during low speed driving, spoiler 11 becomes the state of closing.At this moment, spoiler 11 keeps tilt angle theta
1, in order to rotate when being subject to travelling the wind-force W of wind, the guiding device 10 shown in this and the first embodiment is same.At this, also set for, keep tilt angle theta by rake 11b1 and vehicle side installing component 12 butts of being located at spoiler installation portion 11b
1And then when the wind-force W of the wind that travels becomes directed force F than the 1st torsion spring 20 when large, spoiler 11 rotates to rear view of vehicle side (around conter clockwise).
When running at high speed shown in Fig. 4 (b), Fig. 5 (b), spoiler 11 becomes the state of opening, and reaches desirable angle θ at spoiler 11 with respect to the tilt angle theta towards the direction of vehicle front side
2The time, retainer 13 and vehicle side installing component 12 butts, thus, the rotation of spoiler 11 is restricted.But, in the 2nd embodiment, because retainer 13 and spoiler 11(spoiler installing component 11b) be connected via the 2nd torsion spring 21, therefore, restriction to rotation is temporary transient, when the masterpiece larger than the resulting power of application force addition (F+F2) of the 1st torsion spring 20 and the 2nd torsion spring 21 is used for spoiler 11, sometimes reach desirable angle θ
2Above tilt angle theta 3.In addition, the directed force F of directed force F 2 to the 1 torsion springs 20 by making the 2nd torsion spring 21 is large, can be further clearly at desirable angle θ
2The restriction of place to rotating.
Under the state of the obstacle 30 shown in Fig. 4 (c), Fig. 5 (c) and spoiler 11 collisions, retainer 13 remains on the state with spoiler installation portion 12 butts, only has spoiler 11 to rotate to the rear view of vehicle side.At this moment, spoiler 11 effect have the directed force F of the 1st torsion spring 20 and the 2nd torsion spring 21 directed force F 2 the two.Therefore, after this, when finishing with contacting of obstacle 30, spoiler 11 returns to the state of (b) of (b), Fig. 5 of Fig. 4, thereby becomes following state: the directed force F 2 of the 2nd torsion spring 21 discharges, and only effect has the directed force F of the 1st torsion spring 20.Like this, so long as spoiler 11 can turn to desirable angle θ
2Above such structure, even contact with obstacle 30, spoiler 11 is not fragile yet, can guarantee safety even therefore increase overhang yet.
Among two embodiment shown in above, torsion spring as application of force unit, but also can be used application of force unit beyond the torsion spring.In addition, if only by the torsion spring application of force, then exist because the such wind major reason in addition of travelling of the concavo-convex vibration that causes on the storm wind that sweeps suddenly or road surface moves such worry so that spoiler is smacked one's lips.Therefore, be preferably formed and be such structure: the resistance parts are set between S. A. and spoiler, and thus, spoiler rotates when being subject to the application force of torsion spring lentamente.
In addition, the spoiler of embodiment constitutes: also keep tilt angle theta under the state of closure
1, in order to easily rotate by the wind that travels., in this structure, because spoiler always is in from the outstanding a little state of vehicle, therefore can think that outward appearance is bad.Therefore, can form such structure: when stopping or during low speed driving, the angle of inclination that makes spoiler is zero, perhaps spoiler is accommodated in the vehicle, only makes spoiler outstanding when running at high speed.In this case, can constitute: because the wind that travels works in the negative pressure that the vehicle lower surface produces, thereby spoiler is opened.For example, can constitute: make the cross sectional shape of spoiler form the shape of easily opening by means of negative pressure, after spoiler is opened a little by means of negative pressure, thereby the collision of the front surface of travel wind and spoiler is rotated spoiler.
In addition, the material of spoiler is made as basic material with resin, but, for example the part of the end side by making spoiler about half is that rubber is made, and can keep to a certain extent the rigidity of spoiler, simultaneously, even with the obstacle collision, also can make spoiler be difficult for damaging.
