Abstract
The utility model discloses a water conservancy diversion structure of car side door threshold portion. According to the utility model discloses, water conservancy diversion structure of car side door threshold portion includes tail gate (2) and the side door threshold guide plate (3) that sets up below tail gate (2). Wherein, be provided with along the guide plate chamfer face (10) of automobile body fore -and -aft direction extension on the upper portion of side door threshold guide plate (3), guide plate chamfer face (10) includes: go up inclined plane (11), follow the intermediate position orientation of tail gate (2) lower part and extend than the direction (B) that wheel centre (A) leaned on last direction to lift up. From this, the air current mutual interference that can prevent to follow the air current that flows in vehicle the place ahead towards the back lower place and flow from vehicle chassis.
Description
Technical field
The utility model relates to a kind of flow-guiding structure of automobile side threshold portion.
Background technology
When running car, gate threshold place after automobile side, flows downward from vehicle front to towards rearward air-flow, mutually disturbs with the air-flow flowed out from car chassis, thus aligns the automobile generation resistance travelled.
Consider the problems referred to above, usually deflecting plate is set at automobile side threshold place, air-flow in driving process is guided, therefore, need to carry out appropriate design to automobile side threshold deflecting plate shape and automobile side tail gate shape suitably to guide air-flow, thus reduce to align the resistance at the automobile travelled.
Utility model content
The utility model proposes to solve the problem, and its object is to the flow-guiding structure providing a kind of air-flow that can prevent flowing from vehicle front towards the back lower place mutually to disturb with the air-flow flowed out from vehicle chassis.
To achieve these goals, the flow-guiding structure in automobile side back door threshold portion of the present utility model has following formation: the side door sill deflecting plate comprising tail gate and arrange below tail gate, wherein, the deflecting plate fillet surface extended along vehicle body fore-and-aft direction is provided with on the top of side door sill deflecting plate, deflecting plate fillet surface comprises: ramp, extends from the direction that the midway location of tail gate bottom lifts towards the direction more top than wheel center.
Preferably, the bottom of tail gate is formed with the bearing of trend tail gate fillet surface parallel with the bearing of trend of ramp.
Preferably, the broadening outside car along the vertical distance on the cross section in overall width direction of ramp and tail gate fillet surface.
According to the utility model, can prevent the air-flow flowed towards the back lower place from vehicle front from mutually disturbing with the air-flow flowed out from vehicle chassis in vehicle travel process.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the flow-guiding structure in automobile side back door threshold portion according to the utility model embodiment;
Fig. 2 is the section drawing along the C-C line cutting in Fig. 1.
Nomenclature:
1 ... vehicle, 2 ... tail gate, 3 ... side door sill deflecting plate, 10 ... deflecting plate fillet surface, 11 ... ramp, 12 ... tail gate fillet surface, A ... wheel center, B ... ramp bearing of trend, B ' ... the bearing of trend of tail gate bottom
Detailed description of the invention
Below, embodiment of the present utility model is described in detail with reference to accompanying drawing.
Fig. 1 is the schematic diagram of the flow-guiding structure in automobile side back door threshold portion according to the utility model embodiment, and Fig. 2 is the section drawing along the C-C line cutting in Fig. 1.
In FIG, left side represents vehicle front, that is, the working direction of vehicle, and right side represents rear view of vehicle.In fig. 2, left side represents vehicle interior side, and right side represents vehicle outside.
As shown in Figure 1, vehicle 1 comprises tail gate 2 and the side door sill deflecting plate 3 of setting below tail gate 2.As depicted in figs. 1 and 2, be provided with the deflecting plate fillet surface 10 extended along vehicle body fore-and-aft direction on the top of side door sill deflecting plate 3, and deflecting plate fillet surface 10 comprises the direction B extension ramp 11 lifted towards the direction more top than wheel center A from the midway location of tail gate 2 bottom.Further, the bottom of tail gate 2 is set to almost parallel with the bearing of trend B of side door sill deflecting plate 3 ramp 11 towards the bearing of trend B ' of rear view of vehicle.
As can be seen from Figure 2, deflecting plate fillet surface 10 is being roughly interior narrow outer wide " eight " font with tail gate fillet surface 12 according to the shape on the cross section of hatching C-C cutting, that is, the broadening outside car along the vertical distance on the cross section in overall width direction of ramp 11 and tail gate fillet surface 12.
In the utility model, by be provided with on the top of side door sill deflecting plate along vehicle body fore-and-aft direction extend comprise deflecting plate fillet surface, and the ramp of the direction extension of lifting towards the direction more top than wheel center from the midway location of tail gate bottom is provided with at deflecting plate fillet surface, thus can by guiding obliquely upward from the air-flow of vehicle front flowing underneath backward of producing in travelling at vehicle, and enough reduce during vehicle travels the air-flow flowed to the wheel back lower place from operator's compartment produced, can prevent from thus mutually disturbing from vehicle front to the air-flow flowed towards the back lower place with the air-flow flowed out from car chassis.
Further, by forming the bearing of trend B ' tail gate fillet surface 12 parallel with the bearing of trend B of ramp in the bottom of tail gate, thus the unfavorable factor flowing out area increase or pressure increase etc. towards upper air-flow can be avoided, be easy to guide air-flow.
Further, by broadening outside car along the vertical distance on the cross section in overall width direction of ramp and tail gate fillet surface, above-mentioned effect can be obtained better.
The utility model is not limited to above-described embodiment, when not departing from the utility model scope, can carry out various changes and modifications.
