Abstract
The utility model relates to a rear vehicle spoiler for reducing a drag coefficient. The rear vehicle spoiler is arranged at the rear part of a top cover of a vehicle body or the top of a trunk hatch door in the height direction of the vehicle body, adopts a portal structure, and comprises a spoiler main body and wing end plates, wherein the wing end plates are arranged at two ends of the spoiler main body, are bent downwards and are bilaterally symmetrical; the plate surfaces of the wing end plates are relatively fixed on the vehicle body or the trunk hatch door. The rear vehicle spoiler is characterized in that the rear part of the upper surface of the spoiler main body in the front-back direction of the vehicle body is a fillet transition area. According to the technical scheme, separation points of air and a vehicle running at a high speed are moved backwards, the range of a turbulent flow area at the rear part of the vehicle is narrowed, and the aim of reducing the drag coefficient is achieved.
Description
Technical field
The utility model relates to a kind of auto parts and components, particularly relates to a kind of vehicle rear spoiler for reducing air resistance coefficient.
Background technology
Spoiler is arranged on top, parking stall, and its effect is mainly the lift for less vehicle tail.
Along with the develop rapidly of automotive technology, air pertormance, the environmental protection and energy saving etc. of automobile becomes the important indicator of weighing automobile quality, more and more causes people's attention.Reducing windage is the important means that reduces oil consumption in auto trade.Statistics shows: in the time that Vehicle Speed exceedes 70km/h, windage just becomes the main source of external motion resistance.Due to increasing and the raising of the speed of a motor vehicle of express highway, windage is increasing on the impact of oil consumption.Therefore, reduce windage and become the important technical parameter that auto trade is competitively chased.In addition, the competition of auto trade reduces air resistance coefficient under the prerequisite that changes local sculpt, the target that Shi Ge auto vendor is pursued.Existing vehicle spoiler room for improvement in aerodynamic performance is very large.
Golf ball surface is designed with pit.Air stream can separate with spheroid in the time that the leading edge of ball flows to rear again.Meanwhile, the rear of ball has a turbulent wake zone, in this regional gas stream fluctuating disturbance, causes the pressure at rear lower; The scope of wake flow can affect the size of drag force.Little pothole can make air form the thin turbulent boundary layer that one deck is close to ball table, makes level and smooth air-flow along spherical walk back of work more, and reduces the scope of wake flow, therefore has the suffered drag force of ball of pothole approximately to only have the half of level and smooth ball.
Utility model content
The purpose of this utility model is to provide a kind of automobile spoiler that reduces air resistance coefficient, makes to move after air and the vehicle separation point of running at high speed, and reduces vehicle rear turbulent region scope and effectively improve aerodynamic performance and the environmental protection and energy saving of vehicle.
For achieving the above object, the technical solution adopted in the utility model is:
For reducing a vehicle rear spoiler for air resistance coefficient, be arranged on the rear portion of car body top cover or the boot hatch door tip position along bodywork height direction; Vehicle rear spoiler is door type structure, comprise spoiler main body and at the two ends of spoiler main body bending and symmetrical wing tip plate downwards, wing tip plate plate face be relatively fixed on vehicle body or or boot hatch door on; It is characterized in that: described spoiler main body upper surface is fillet transitional region along the rear portion of vehicle body fore-and-aft direction; Described spoiler main body upper surface is along being uniformly distributed some pits on the rear portion fillet transitional region of vehicle body fore-and-aft direction.
By technique scheme, on described fillet transitional region, pit is sphere pit.
By technique scheme, on described fillet transitional region, to appoint the maximum linear scope of point-to-point transmission be 5-50mm to the outer rim of same pit.
The utility model improves on the rear spoiler that vehicle body is raised preventing in Vehicle Driving Cycle process, has been uniformly distributed the sphere pit of some similar golf ball surfaces at spoiler main body upper surface rear portion fillet transitional region by rule.After the vehicle separation point that makes air and run at high speed, move, reduce vehicle rear turbulent region scope, reach the object that reduces air resistance coefficient.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1;
Fig. 3 is the section drawing in B cross section in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of vehicle rear spoiler for reducing air resistance coefficient shown in Fig. 1-3, is arranged on the rear portion of car body top cover or the boot hatch door tip position along bodywork height direction; Vehicle rear spoiler is door type structure, comprise spoiler main body and at the two ends of spoiler main body 1 bending and symmetrical wing tip plate 2 downwards, wing tip plate 2 plate faces be relatively fixed on vehicle body or or boot hatch door on; Referring to Fig. 2, described spoiler main body 1 upper surface is fillet transitional region 3 along the rear portion of vehicle body fore-and-aft direction.
Referring to Fig. 1-3, described spoiler main body 1 upper surface is along being uniformly distributed some pits 4 on the rear portion fillet transitional region 3 of vehicle body fore-and-aft direction.
Referring to Fig. 3, the sphere sphere pit 4 that in described spoiler main body 1, pit 4 is similar golf ball surface.
By technique scheme, in described spoiler main body 1, to appoint the maximum linear scope of point-to-point transmission be 5-50mm to the outer rim of same pit 4.
The utility model improves on the rear spoiler that vehicle body is raised preventing in Vehicle Driving Cycle process, has been uniformly distributed the sphere pit of some similar golf ball surfaces at spoiler main body upper surface rear portion fillet transitional region by rule.After the vehicle separation point that makes air and run at high speed, move, reduce vehicle rear turbulent region scope, reach the object that reduces air resistance coefficient.
