Abstract
The invention discloses a lower spoiler of a rear floor used for reducing wind resistance coefficient of a finished automobile. The lower spoiler of the rear floor comprises two spoiler bodies which are connected below a rear floor assembly and are arranged in front of an oil tank, and the two spoiler bodies are arranged in a bilateral symmetry manner. The lower spoiler of the rear floor is characterized in that each spoiler body is an elongated thin-wall overall plastic injection part and is formed by an upper surface, sides respectively connected with the two ends of the upper surface and an inclined plane which is connected with the front edge of the upper surface and is connected with the front edge of each of the two sides, the inclined plane of each spoiler body inclines backward from top to bottom, and an included angle alpha between the inclined plane and the horizontal plane is 50+/-5 degrees. The lower spoiler of the rear floor used for reducing the wind resistance coefficient of the finished automobile disclosed by the invention can be used for bearing the impact of air current at the bottom in a vehicle travelling process, interfering with smooth and rapid flow of the air current, reducing the positive pressure of a position at the bottom of the oil tank, reducing the wind resistance coefficient of the finished automobile and reducing the oil consumption; and the lower spoiler of the rear floor used for reducing the wind resistance coefficient of the finished automobile disclosed by the invention is simple in structure, light in weight and low in cost, is easy to manufacture and can be used for reducing the use cost of the finished automobile.
Description
Technical field
The present invention relates to a kind of auto parts and components, be specifically related to spoiler under a kind of back floor that is used to reduce the car load air resistance coefficient.
Background technology
Along with expanding economy, the raising of living standards of the people, automobile has become one of important vehicle that people ride instead of walk.Simultaneously, owing to energy scarcity, petrol and diesel oil price rise steadily, the user more and more payes attention to automobile fuel consumption.The height of car load air resistance coefficient has directly influenced the size of the resistance to motion of automobile, and then has influenced the oil consumption in the normal use.Therefore, in the car load development process, all can reduce air resistance coefficient as much as possible through structure optimization.In car load exploitation in the past,, be common through spoiler being set reducing air resistance coefficient in automobile tail, anterior outside; But; Realize that through below the floor, back, spoiler being set the scheme that reduces air resistance coefficient is left in the basket basically, at present, still do not have similar products like.
Summary of the invention
The purpose of this invention is to provide spoiler under a kind of back floor that is used to reduce the car load air resistance coefficient, it can effectively reduce the malleation of fuel tank bottom, and then reduces resistance to motion, reduces oil consumption.
Spoiler under a kind of back floor that is used to reduce the car load air resistance coefficient of the present invention; Comprise that two are connected below the floor assembly of back and are positioned at fuel tank fwd spoiler body; Two spoiler bodies are symmetrically arranged; It is characterized in that: said spoiler body is a strip shape thin-walled integral molded plastic spare, is made up of with the dip plane that links to each other with the front of upper surface and link to each other with the front of two sides upper surface, the side that links to each other with the upper surface two ends respectively; The dip plane of said spoiler body recedes from top to bottom, and the angle between said dip plane and the horizontal surface is 50 ° ± 5 °.Underfloor is provided with symmetrical spoiler body in the back, and is originally smooth-going fast through the air-flow of body bottom section to upset, and reduces fuel tank bottom malleation and reduces resistance to motion.
Further, the middle part of the upper surface of said spoiler body is provided with that first mounting hole, an end are provided with second mounting hole, the other end is provided with the 3rd mounting hole; Said first mounting hole, second mounting hole and the 3rd mounting hole respectively be located at the back floor assembly bolt corresponding matching that is, and connect fixing respectively through the belt washer nut.
Further, be respectively arranged with reinforced rib around first mounting hole on said upper surface, second mounting hole and the 3rd mounting hole.
Further, on the back of the dip plane of said spoiler body, be provided with crisscross reinforced rib.
Beneficial effect of the present invention: can in vehicle traveling process, bear the impact of bottom air-flow, the smooth-going of disturbing flow flows fast, reduces the malleation of fuel tank bottom position, reduces the car load air resistance coefficient, reduces oil consumption; Simple for structure, to make easily, weight is very little, and is with low cost, can be reduced in the use cost of car load.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
Referring to spoiler under the described a kind of back floor that is used to reduce the car load air resistance coefficient of Fig. 1, Fig. 4, Fig. 5, Fig. 6 and Fig. 7; Comprise that two are connected below the floor assembly 3 of back and are positioned at 1, two spoiler body 1 of fuel tank 4 fwd spoiler bodies and are symmetrically arranged; Said spoiler body 1 is a strip shape thin-walled integral molded plastic spare, and the dip plane 15 that is linked to each other and linked to each other with the front of two sides 11 by upper surface 13, the side 11 that links to each other with the upper surface two ends respectively and front with upper surface 13 constitutes; The dip plane 15 of said spoiler body 1 recedes from top to bottom, and the angle between said dip plane 15 and the horizontal surface is 50 °.Underfloor is provided with symmetrical spoiler body in the back, and is originally smooth-going fast through the air-flow of body bottom section to upset, and reduces fuel tank bottom malleation and reduces resistance to motion.
Further, the middle part of the upper surface 13 of said spoiler body 1 is provided with that first mounting hole 12, an end are provided with second mounting hole 14, the other end is provided with the 3rd mounting hole 16; Said first mounting hole 12, second mounting hole 14 and the 3rd mounting hole 16 respectively be located at bolt 31 corresponding matching that back floor assembly 3 is, and connect fixing through belt washer nut 2 respectively.
Further, be respectively arranged with reinforced rib around first mounting hole 12 on said upper surface 13, second mounting hole 14 and the 3rd mounting hole 16, to guarantee the intensity at attachment point place.
