Abstract
The utility model provides a rear wheel cover of an automobile, belongs to the technical field of automobiles, and solves the problem that the entire automobile structure vibration and the noise are produced since a rear wheel cover plate in an existing automobile body is easily subject to other power during the running process of the automobile. The rear wheel cover of the automobile comprises a rear wheel cover plate with a bent part; and a flaky damping sheet made of non-metallic material is fixedly connected to the surface of the bent part of the rear wheel cover plate. The rear wheel cover of the automobile has the advantages of simple structure, convenient manufacture, and obvious reduction effect of vibration of the rear wheel cover plate and noise.
Description
Technical field
The utility model belongs to automobile technical field, particularly relates to a kind of automobile back wheel cover.
Background technology
Along with developing of automobile industry, people are more and more higher to the requirement of " safety, traveling comfort, the feature of environmental protection " of car, and the standard-required to " sound insulation, vibration isolation, anticorrosion, noise control " in the car passenger cabin also constantly promotes.The AE personnel have located to do the technology upgrading of sound insulation vibration isolation to ride-control, sound-heat insulated cushion, car internal sound insulation, vibration isolation carpet, vehicle body sticking glass, car roof etc. in car at present, make vibration and noise in the car passenger cabin obtain the actv. improvement.
The source of internal car noise comprises air-flow noise, motor noise, chassis noise, wheel cover noise and tail gas noise etc.Wherein to exist resonance point low for the inner rear wheel arch in the car body, in the car driving process, is easy to be subjected to other excitations and produces complete vehicle structures vibration and noise.In earlier stage be difficult to overcome the problems referred to above at new model, and in development late stage if rear wheel cover is redesigned, just relate to design modification and from the new die exploitation, thereby prolonged the design cycle and improved design research and development expense.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind ofly the cover plate vibrational energy to be converted into heat energy, reaches the automobile back wheel cover that reduces noise.
The purpose of this utility model can realize by following technical proposal: a kind of automobile back wheel cover, comprise inner rear wheel arch with curve, and it is characterized in that the surface of described inner rear wheel arch curve is fixed with adopts non-metallic material to make in the form of sheets damping panel.
Inner rear wheel arch in the automobile back wheel cover is fixed on the vehicle body of automobile, and inner rear wheel arch adopts metal sheet to make and by punch forming.When being subjected to the dynamic excitation vibration, inner rear wheel arch just can make damping panel with its stretching or compressive strain, thereby in each period of vibration, the vibrational energy of inner rear wheel arch is converted into the heat energy of damping panel, reaches the vibration and the noise that reduce Wheelhouse panel by the viscid characteristic of damping panel.
In above-mentioned automobile back wheel cover, described damping panel is positioned on the lateral surface of inner rear wheel arch curve.This structure can damping panel more be subjected to the vibration effect of inner rear wheel arch, and the stretching of damping panel or compressive strain are increased, and improves energy transformation ratio.
In above-mentioned automobile back wheel cover, described damping panel adopts asphalt material to make.Cheap, viscid characteristic advantage obvious, easy to use that pitch has.
In above-mentioned automobile back wheel cover, the thickness of described damping panel is 2～3mm.
Compared with prior art, this automobile back wheel cover has vibration and the tangible advantage of noise effects simple in structure, easily manufactured, as to reduce Wheelhouse panel.
Description of drawings
Fig. 1 is the perspective view of this automobile back wheel cover.
Fig. 2 is the structural representation at another visual angle of this automobile back wheel cover.
Among the figure, 1, vehicle body; 2, inner rear wheel arch; 3, damping panel.
The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As depicted in figs. 1 and 2, the automobile back wheel cover comprises inner rear wheel arch and damping panel.
Specifically, inner rear wheel arch is fixed on the vehicle body, and it adopts metal sheet to make and makes its middle part form curve by punch forming.Damping panel in the form of sheets and the non-metallic material of employing with viscid characteristic itself make, the non-metallic material that present embodiment provides is a pitch.
Damping panel is positioned on the lateral surface of inner rear wheel arch curve, and the thickness of damping panel is 2～3mm, and the thickness of the present embodiment that provides in the accompanying drawing is 2.5mm, and its thickness also is preferred value.One side with damping panel is sticked on the plate face of inner rear wheel arch aborning, again through baking.Because the properties of materials of damping panel own, the damping panel that asphalt material is made just can be bonded on the inner rear wheel arch that metallic material makes and both are connected mutually.
When inner rear wheel arch is subjected to the dynamic excitation vibration, just can make damping panel with its stretching or compressive strain, thereby in each period of vibration, the vibrational energy of inner rear wheel arch is converted into the heat energy of damping panel, reaches the vibration and the noise that reduce Wheelhouse panel by the viscid characteristic of damping panel.
Specific embodiment described herein only is that the utility model spirit is made casehistory.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used vehicle body morely; Inner rear wheel arch; Curve; Terms such as damping panel, but do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
Claims (4)
1. an automobile back wheel cover comprises the inner rear wheel arch (2) with curve, it is characterized in that, the surface of described inner rear wheel arch (2) curve is fixed with adopts non-metallic material to make in the form of sheets damping panel (3).
