Abstract
The invention provides a rear floor for an automobile. A deep punching region serving as a spare wheel storage slot is arranged at a position, close to the rear part, of the rear floor; the center of the spare wheel storage slot serves as a spare wheel installation point; a first group of reinforcing ribs are radially arranged at the bottom of the spare wheel storage slot by using the spare wheel installation point as a center; the first reinforcing ribs extend to the rim of the bottom of the spare wheel storage slot; a second group of reinforcing ribs are distributed at a circle of the side periphery of the spare wheel storage slot from the bottom of the spare wheel storage slot to the upper part of the rear floor; and a third group of reinforcing ribs are distributed on the upper part of the rear floor along the circle of the spare wheel storage slot. In the rear floor for the automobile with the structure, the reinforcing ribs are designed and distributed rationally, so that the weight of the whole automobile can be reduced, the oil consumption can be reduced, and the noise, vibration and harshness (NVH) performance of the rear part for the automobile can be enhanced.
Description
Technical field
The present invention relates to a kind of body construction in auto body field, be specifically related to a kind of back floor of automobile.
Background technology
The NVH performance of automobile is the standard of estimating the automotive performance quality that latest developments are got up.The structure design of car body each several part all should be considered the Effect on Performance to automobile NVH.Because the automobile rear floor rear portion is the place of depositing the car spare tyre, this position rigidity relatively a little less than, be easy to generate local mode.In the driving process, be easy to reduce the NVH performance, influence the quality of vehicle because resonance causes the generation of noise in the car.Therefore structure design herein just seems particularly important.The method of conventional enhancing rigidity is that to increase the material material thick, but does the weight that can increase car load like this, has improved the car load oil consumption virtually, and the structure design on floor needs to consider carefully after the institute.
The rear floor structure of automobile mainly contains following several now:
A kind of is plate shaped floor, and this kind floor does not have reinforced rib to arrange, only uses the method that increases ground, back plate thickness to come panel stiffness intentinonally, and this floor can greatly increase the weight of vehicle body, improves the oil consumption of automobile.
A kind of floor is that the reinforced rib degree of depth is not enough and arbitrarily arrange, though the intensity on floor, back can be improved in this floor, owing to the spatial destribution of reinforced rib does not think over, and the degree of depth of reinforced rib is also not enough, still can not satisfy the NVH performance demands.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of new automobile rear floor, and the NVH performance of automobile rear can be improved in this floor, back under the prerequisite that satisfies vehicle body various aspects of performance (bending stiffness, torsional stiffness etc.), and can alleviate complete vehicle weight, reduces oil consumption.
For solving the problems of the technologies described above, the present invention takes following technical scheme:
A kind of back floor of automobile, the floor, back to have deep-draw zone by rear positions be the spare tyre storage tank, the center of this spare tyre storage tank is the spare tyre attachment point.Is that the center is radial arrangement first group of reinforced rib arranged in the bottom of described spare tyre storage tank with the spare tyre attachment point, and described first reinforced rib extends to the edge of spare tyre storage tank bottom; Side at the spare tyre storage tank makes a circle from being furnished with second group of reinforced rib to top, floor, back bottom it; Top on the floor, back is distributed with the 3rd group of reinforced rib along spare tyre storage tank one circle.
The part of described second group of reinforced rib is connected with the part of the 3rd group of reinforced rib.
Described first group of reinforced rib has five, and width is between 60mm-90mm, and the degree of depth is 6mm, wherein has three in spare tyre storage tank front portion, has two at the rear portion.
Described first group of reinforced rib has nine, and has three three reinforced ribs with top, floor, back to link.
The automobile rear floor of above structure, the design of its reinforced rib is reasonable with distribution, can alleviate complete vehicle weight, reduces oil consumption, also can improve automobile rear NVH performance.
Description of drawings
Fig. 1 is the front view on floor, back.
Fig. 2 is the shaft side figure on floor, back.
The specific embodiment
Referring to Fig. 1, Fig. 2, back floor a huge deep-draw zone is arranged in order to deposit spare tyre, be spare tyre storage tank 21, wherein this has the spare tyre mounting hole, is that five first group of reinforced ribs 11 have been arranged in the center of circle in spare tyre storage tank 21 bottoms with the spare tyre mounting hole, and between the 90mm, the degree of depth is 6mm to the width of these five reinforced ribs at 60mm.Three reinforced ribs are wherein arranged forwardly, two reinforced ribs are arranged, and these five reinforced ribs extend to the edge of spare tyre storage tank 21 bottoms, floor, back at the rear portion.These five reinforced ribs play the effect of strengthening back floor bottoms field strength.
In addition, the gusset 22 1 at spare tyre storage tank 21 encloses from the bottom to top nine the second group of reinforced ribs 12 that also distributed.The width of these muscle about 55mm, the about 7mm of the degree of depth.Be distributed with the 3rd group of reinforced rib 12 of a circle on top, floor, back 23, the shape difference of these muscle, the top on floor after being centered around.These muscle work to strengthen intensity equally and improve part process, based on technological consideration, with wherein three the 2nd u reinforced ribs and three the 3rd group of reinforced ribs be connected together.
Like this, the reinforced rib in these three zones has improved the rigidity of back floor area by rational spatial destribution, has improved this regional mode, has improved the NVH performance of back floor area.
