Abstract
The utility model relates to a wind shield air curtain for motorcycles, which can prevent upwind wind flow for riders of the motorcycles. The front part of the motorcycle is provided with a windward face (1) to punch the speed of the upwind wind flow on the windward face, and a fairing on the windward face is used for forming upward air jet flow, namely, the air curtain. The air curtain is used for preventing the upwind air flow from being blown to the position of the riders.
Description
The utility model relates to a kind of air curtain that keeps out the wind that utilizes aerodynamic force to form.
Usually do not have the equipment that keeps out the wind on the motor bike, the driver is in against the wind in the air-flow when travelling, and the strong eyesight that can give the people against the wind, hearing, skin etc. cause harmful effect, and the people is felt cold.Motor bike is because light and flexible is not suitable for adorning the bulk Windshield.The Windshield of fritter is housed on some motor bike, but windproof effect is not obvious, and Windshield can block vision.
The purpose of this utility model is that a kind of air curtain little, that do not stop driver's sight line that takes up room equipment that keeps out the wind will be provided.
The purpose of this utility model is achieved in that a windward side is set that during motorcycle driving, the speed punching press of air-flow will form certain pressure on this face against the wind before motor bike.Then by the fairing on the windward side, this air pressure is formed the airstream that makes progress together, this one airstream is air curtain, and it works the effect of keeping out the wind to driver present position thereafter.Because air curtain is to be stamped into power with the speed of air-flow against the wind, therefore, air curtain also strengthens when strengthening against the wind, and the driver will not be subjected to blowing against the wind all the time.
Windshied part of the present utility model is divided into air curtain, does not enlarge the solid space of motor bike, is fit to the characteristics of motor bike light and flexible.The operation material of air curtain is an air in addition, does not stop driver's sight line.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is vertical part surface (side-looking) figure of air curtain device that the utility model proposes.
Fig. 2 is the block diagram of air curtain device shown in Figure 1.
Fig. 3 is that air curtain device shown in Figure 1 is connected the situation scheme drawing with motor bike.
In conjunction with Fig. 1, Fig. 2, (1) indication is the windward side of air curtain device, and (2) are the fairing on the windward side, and windward side (1) and fairing (2) all are in against the wind in the air-flow (3).(1) makes air along the ejection of the slit between windward side (1) and the fairing (2) upward because the effect of speed punching press forms certain pressure to air-flow (3) in the windward side against the wind, forms airstream one, i.e. air curtain (4).In order to increase the air-flow velocity of air curtain, the spacing distance between windward side (1) and the fairing (2) is reduced along the air motion direction, in windward side (1) and fairing (2), form the space of a contraction, when being flowed therein, air-flow quickens.Because the barrier effect of air curtain (4), air-flow (3) will blow the residing space less than driver behind the air curtain against the wind.(5) indication is a connecting panel, and windward side (1) and fairing (2) are linked together.
Fig. 3 is that air curtain device is connected the situation scheme drawing with motor bike.The windward side of air curtain (1) is installed in the anterior handrail of motor bike with upper/lower positions, and its upper limb slightly protrudes from handrail, and protrusion height is advisable not influence driver's sight line.
In the present embodiment, air curtain device is mainly driver's head and upper body keeps out the wind.Special windward side and fairing to both sides can also be installed, and for driver's arm and shank keep out the wind, the device that keeps out the wind for shank can be installed on the vehicle body position.
Claims (2)
1. be used to the driver to stop against the wind the motor bike of the air-flow air curtain that keeps out the wind on the motor bike, it is characterized in that there is windward side (1) the motor bike front portion, has fairing (2) on the windward side.
2. the motor bike according to claim 1 air curtain that keeps out the wind is characterized in that the spacing distance between windward side (1) and the fairing (2) reduces along the air motion direction.
