Abstract
The utility model relates to a rear wheel cover of a car. The rear wheel cover of the car comprises a rear wheel cover body, wherein the rear wheel cover body comprises an arched enclosure plate and a top plate, the three faces of the top plate are in smooth connection with the corresponding side faces of the arched enclosure plate respectively to form a semi-open cavity, and a plurality of reinforcing ribs are arranged on the arched enclosure plate in the circumferential direction of the arched enclosure plate. Due to the fact that the reinforcing ribs are arranged on the arched enclosure plate in the circumferential direction of the arched enclosure plate, the shape and the structure of the cross section of the arched enclosure plate are changed, the rigidity of the arched enclosure plate is improved, the resonant frequency is increased, and the purpose of reducing vibration and the purpose of lowering noise are achieved.
Description
Technical field
The utility model relates to field of automobile, is specifically related to automobile rear-wheel cover.
Background technology
Along with the development of auto-industry, people are more and more higher to the requirement of " safety, traveling comfort, the feature of environmental protection " of car, in car passenger cabin, the standard-required of " sound insulation, vibration isolation, anticorrosion, noise control " also constantly promoted.About sound insulation and vibration isolation people, constantly exploring and studying, the source of internal car noise comprises air-flow noise, motor noise, chassis noise, wheel cover noise and tail gas noise etc.Rear wheel cover is normally arranged on automotive floor panel by fabricated section, also can directly be welded on automotive floor panel, because it exists resonance point low, in car driving process, is easy to be subject to other excitations and produces complete vehicle structure vibration and noise.
Summary of the invention
The problems referred to above that exist for prior art, the technical problems to be solved in the utility model is: how a kind of automobile rear-wheel cover is provided, reduces as far as possible vibration and the noise of rear wheel cover.
Solve this technical problem, the utility model adopts following technical scheme: automobile rear-wheel cover, comprise rear wheel cover body, and it is characterized in that: described rear wheel cover body comprises arch coaming plate and top board, three of the described top board corresponding side surface smooth connections with arch coaming plate, form a semi-open cavity; Described arch coaming plate is circumferentially with some reinforced ribs along it.
As optimization, described arch coaming plate and top board are structure as a whole.Further improve the globality of automobile rear-wheel cover, improved resonance frequency, reduced vibration and noise.
As optimization, described reinforced rib is the groove by cavity inner side depression described in cavity lateral.Arranging of groove changed
The version of the cross-sectional plane of automobile rear-wheel cover, thus the rigidity of automobile rear-wheel cover improved, also alleviated the weight of rear wheel cover simultaneously.
As optimization, the length of described groove smoothly extends to the middle part of top board Width from arch coaming plate.
As optimization, described arch coaming plate 3 is positioned at bottom and prolongs its circumferential side while using and has to the flange away from cavity.
With respect to prior art, the utlity model has following advantage: the automobile rear-wheel cover that the utility model provides, owing to being circumferentially with some reinforced ribs at arch coaming plate along it, thereby shape and the structure of arch coaming plate cross-sectional plane have been changed, improved the rigidity of arch coaming plate, improve resonance frequency, thereby reach the object that reduces vibration and noise.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment.
Fig. 2 is the upward view structural representation of embodiment.
In figure, groove 1, top board 2, arch coaming plate 3, flange 4.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Orientation when the utility model middle left and right, forward and backward orientation are described and referred to automobile back wheel and cover on use state, automobile back wheel covers under use state, and headstock is the place ahead.
embodiment:referring to Fig. 1, automobile rear-wheel cover, comprises rear wheel cover body, and described rear wheel cover body comprises arch coaming plate 3
With top board 2, with the corresponding side surface smooth connection of arch coaming plate 3, form a semi-open cavity; The side that top board 2 is corresponding with arch coaming plate 3 is arch coaming plate 3 left side arcs or right side cambered surface, can adopt welding manner to connect, arch coaming plate 3 and top board 2 are preferably integrative-structure, this not only can further improve the globality of automobile rear-wheel cover, improves resonance frequency, reduces vibration and noise, and while producing, rear wheel cover can be passed through one-step casting drawing and forming, and production efficiency is higher, also convenient while being arranged on automotive floor panel.The semi-open cavity that top board 2 and arch coaming plate 3 form, while using this automobile rear-wheel cover, wheel is positioned at this cavity, and in order to improve the rigidity of arch coaming plate 3, arch coaming plate 3 is circumferentially with some reinforced ribs along it.This reinforced rib is preferably the groove 1 by cavity lateral cavity inner side depression, and the length of groove 1 preferably smoothly extends to the middle part of top board 2 Widths from arch coaming plate 3.During concrete enforcement, described groove 1 is preferably circumferentially evenly laid along arch coaming plate 3, and groove 1 number is preferably four.
Arch coaming plate circumferentially has two sides along it, and side is positioned at top while using, three connections of top board 2, and another side is positioned at bottom while using, and for more convenient, arch coaming plate preferably has outside flange on 3 these sides, away from the flange of cavity.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
