Abstract
The utility model discloses a wind shield cover for bicycles. The utility model is characterized in that a cover shell is in the shape approximate to a V shape or a U shape, or the end of the cover shell is in a streamline shape. According to the hydromechanical resistance analysis of the shapes of objects, the point of the V-shaped pointed cover shell can be aligned with a head-on airflow, and the resistance which is generated by the airflow is less than that of a flat plate type cover shell or an arc-shaped cover shell at the moment. The resistance which is generated by the U-shaped cover shell or the round head point of the streamline end of the cover shell is also less than that of the flat plate type cover shell or the arc-shaped cover shell in a similar way. The utility model not only has a wind resistance function but also can reduce the head-on air resistance for a rider when a bicycle runs. Consequently, the physical energy consumption and other energy consumption can be reduced, and particularly, the superiority of the wind shield cover for bicycles is obvious in the process of riding against the wind.
Description
Technical field:
The utility model relates to the annex of unpowered vehicle and a part of self-propelled vehicle, specifically a kind of windshield that is mainly used in bicycle, Electrical Bicycle, mini-motorcycle and motor bike.
Background technology:
The apparatus that keeps out the wind that is used for bicycle, Electrical Bicycle, mini-motorcycle and motor bike at present all is flat or arc slightly, generally be referred to as air baffle, though this air baffle has the effect of keeping out the wind, the resistance on travelling is bigger, and particularly its resistance is particularly evident against the wind the time.
Summary of the invention:
The purpose of this utility model is to provide a kind of automobile-used windshield, and its existing effect of keeping out the wind can make its resistance force diminishes again.
To achieve these goals, the technical solution of the utility model is: automobile-used windshield, it mainly comprises case, it is characterized in that: approximate V-shaped, U type of case or end are stream line pattern.
The utility model is because approximate V-shaped with the windshield design, U type or end are stream line pattern, according to hydromechanical body form resistance analysis, V-shaped tip case is aimed at air-flow head-on with tip, the resistance that produced by air-flow this moment is less than the flat or case of arc slightly, in like manner U type or end are resistance that the round end place of stream line pattern case produces also less than the flat or case of arc slightly, the utility model not only can play the effect of keeping out the wind, can also make the cyclist reduce the air resistance that heads on when car travels, thereby reduce physical efficiency and other energy consumption, especially its preceence is more obvious against the wind the time.
Description of drawings:
Fig. 1 is the structural representation of the utility model one embodiment
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is further described.
The utility model mainly comprises case 1; it is different from prior art and is: approximate V-shaped, U type of case or end are stream line pattern; inwall at case 1 in the enforcement is provided with fabricated section 2; present embodiment is provided with two symmetrical fabricated sections 2 at the inwall of case 1; fabricated section 2 triangular in shape, oblongs; end at fabricated section 2 is provided with a connecting strap 3; this windshield can be installed in the front portion of car; the car front portion is covered; not only have keeping out the wind and reduce the function of resistance, also can protect the front portion of car not drenched with rain.
Claims (4)
