The specific embodiment
In order to make those skilled in the art understand better the utility model, below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated.
Fig. 1 is the block diagram looking over to vehicle front from machinery space, Fig. 2 ~ 5 are using the visual angle of Fig. 1 as with reference to direction, and Fig. 6 is the assembling stereogram looking at vehicle front, and the word such as left and right, upper and lower, forward and backward in the application's book is just in order to distinguish each several part title, and do not should be understood to and be limited.Machinery space is provided with condenser 7 and radiator 6, condenser 7 arranges respectively water tank upper beam and water tank cross sill (not shown) up and down, condenser 7 front ends are horizontal the front anti-collision beam 8 being fixed on front anti-collision beam pillar stiffener 9, described front anti-collision beam 8 belows arrange chin spoiler 1, the both sides of chin spoiler 1 connect respectively left side deflecting plate 2 and right side deflecting plate 3, chin spoiler 1, left side deflecting plate 2 and right side deflecting plate 3 form U-shaped flow-guiding structure, the wherein upper surface of chin spoiler 1, the inside face of left side deflecting plate 2 and right side deflecting plate 3 is selected smooth flat, be conducive to reduce intake air restriction.The lagging dege of described left side deflecting plate 2, right side deflecting plate 3 is respectively equipped with the U-shaped draw-in groove 21,31 mating with front anti-collision beam 8 clampings, lagging dege at left side deflecting plate 2 and right side deflecting plate 3 extends respectively the connecting strap 23,33 being connected with front anti-collision beam pillar stiffener 9 to two outsides, be outward extended with to be pressed on to press sheet 22,32 on front anti-collision beam on the vertical edge of described U-shaped draw-in groove 21,31.
Because front grid (not shown) is divided into upper grid and Under The Grille two parts by front anti-collision beam 8, therefore gas can be divided into upper and lower two parts and enters, successively by condenser 7 and radiator 6.
As shown in Figure 2, the bottom of chin spoiler 1 is provided with three reinforcements 41, wherein two are positioned at two ends, left and right and coordinate with left and right side deflecting plate 2,3 respectively, chin spoiler 1 is fixed on therebetween, another one is located at the middle part, bottom of chin spoiler 1, improve the intensity of chin spoiler 1, avoided its situation that occurs fracture under vehicle high-intensity exercise, the reinforcement of suitable quantity also can be set certainly as required.
For improving the safety performance of guiding device entirety, above-mentioned three reinforcements 41 all extend to the back-end, and be bent to form the lattice catch 42 on the be pressed on water tank cross sill of L-type downwards, in the time bumping in Vehicle Driving Cycle between chin spoiler 1 and front anti-collision beam 8, lattice catch 42 has reduced the impact of both times because increasing area of thrust surface, lattice catch 42 also can spot welding or is riveted on water tank cross sill, further improves the intensity of chin spoiler 1.
It should be noted that, chin spoiler 1, left side deflecting plate 2 and right side deflecting plate 3 and the reinforcement 41 coordinating with left and right side deflecting plate 2,3 are fixedly connected with by bolt or buckle mode.
Because chin spoiler 1, left side deflecting plate 2 and right side deflecting plate 3 are not good with the rear obturation effect of annex installation around, in gap, have partial admission and reveal, make the utilization ratio of front end airflow not high, and the hot gas refluxing in gap also affect radiating efficiency.Therefore contriver left and right side deflecting plate 2,3 with around the peripheral position sealing that contacts of annex be provided with flexible part 5, the material of this flexible part 5 can be EVA(ethylene-vinyl acetate copolymer), PE(polyethylene), CR, PU foam (polyurethane), PORON(polyurethane) or EPE(expandability polyethylene, expanded polyethylene foam), EPP(expandable polypropylene) etc.Like this by enhanced leaktightness space, prevent that the hot air reflow at radiator rear is to positive ventilation inlet, optimized the water conservancy diversion effect of guiding device, flexible material also has the effect of damping noise reduction simultaneously, has avoided vehicle in the process of moving because the infringement causing is clashed in friction.
For the installation question of this automobile guiding device, can prior to front bumper, this guiding device be installed when new car in assembling, even the vehicle having gone on the market is installed after also can simply pulling down front bumper again, therefore applicability is very wide.Concrete mounting means is: left side deflecting plate 2 and right side deflecting plate 3 overlap by connecting strap 23,33 and front anti-collision beam pillar stiffener 9 respectively, U-shaped draw-in groove 21,31 is stuck in above front anti-collision beam 8, chin spoiler 1 bottom front and Under The Grille compress, rear end and water tank cross sill compress, left and right side deflecting plate 2,3 top front ends and upper grid compress, and this mounting structure has guaranteed steadiness and the reliability of guiding device.
In order to test the automobile guide performance of installing after this device, contriver according to have or situation without this guiding device under done related experiment, obtained data as shown in table 1:
| Test event | Pass through air quantity (kg/s) without deflecting plate | There is deflecting plate to pass through air quantity (kg/s) | Lifting ratio |
| Radiator ventilation volume | 0.158 | 0.23 | 45.6% |
| Condenser ventilation volume | 0.182 | 0.26 | 42.9% |
table 1with/without the ventilation volume contrast of radiator and condenser in deflecting plate situation
Wherein " have deflecting plate " and refer to the guiding device that the utility model structure has been installed, can find out and install after this guiding device, the ventilation volume of radiator and condenser is significantly improved.This lifting ratio deflecting plate compared to existing technology has a clear superiority in, and research shows: the deflecting plate ventilation volume of prior art promotes ratio and can only reach at most between 10% ~ 30%.And deflecting plate mentioned in this article is because of its distinctive structure and unique mounting means, add to have adopted reasonable actv. seal approach, the ventilation volume of condenser and radiator is reached more than 40%.
Flow-guiding structure of the present utility model is as independent entirety, installation is firm and installation site is few, each deflecting plate is with around annex obturation effect is good, make can under the guiding of deflecting plate, flow to condenser and radiator by the air of air-inlet grille, the utilization ratio of air-flow get a qualitative improvement, obviously improve the effectiveness of regenerator of condenser and radiator, solved air-conditioning and do not freezed, the radiator tank Practical Project problem such as boil.Simultaneously not only damping noise abatement of flexible material, strengthen preventing airtight time condenser, radiator around heated air stream be back to the air port of advancing.
The automobile guiding device above the utility model being provided is described in detail.The explanation of specific embodiment is just for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also carry out some improvement and modification to the utility model; for example, at design phase; directly deflecting plate and air-inlet grille are made of one, these improvement and modification also fall in the protection domain of the utility model claim.
