Abstract
Backplate at the bottom of a kind of auto body, comprise end panel reality, the lower surface of end panel reality is fixed with needle punched non-woven fabrics, the upper surface of end panel reality is fixed with spunlace non-woven cloth, end panel reality is glass pricker plate, and backplate at the bottom of vehicle body is provided with some water falling holes.Beneficial effect is: not only actv. can be provided to protect to underbody structures such as automotivies engine, but also has the effect of sound insulation and noise reduction, and structure is simple simultaneously, and processing and manufacturing cost is low.
Description
Technical field
The utility model relates to a kind of automobile bottom fail-safe structure, especially relates to backplate at the bottom of a kind of vehicle body.
Background technology
In vehicle traveling process, the rubble on track often jumps the bottom of pounding to auto body.In order to strengthen the protection of bottom of automobile body, especially strengthen the protection to automotive engine, existing volume production vehicle is usually fixed with the automotive engine guar plate adopting the sheet material such as engineering plastic flitch or aluminium alloy plate to make at bottom of automobile body.Problems existing is: although automotive engine guar plate can effectively prevent rubble to the damage of automotive engine, but lack the effect of sound insulation and noise reduction, when rubble hits to automotive engine guar plate, larger clash can be produced, thus affect experiencing by bus of driver and conductor.
Summary of the invention
Main inventive object of the present utility model is to provide one and both effectively can protects bottom of automobile body, has again the effect body bottom guar plate of sound insulation and noise reduction.
The utility model technical scheme used is: backplate at the bottom of a kind of vehicle body, comprises end panel reality, and the lower surface of end panel reality is fixed with needle punched non-woven fabrics.
Wherein, together with needle punched non-woven fabrics to be fixedly linked with smooth end panel reality by cementing method in advance again, and then the method for mold pressing is utilized to make some concaveconvex structures according to the structure of the body bottom using position and for backplate at the bottom of vehicle body being fixed on mounting hole during body bottom.During use, backplate at the bottom of vehicle body is arranged on the below of automotive engine or other structure, and backplate at the bottom of vehicle body is connected with the bottom of auto body with the connection structure such as to be threaded by buckle.In running car way, if have rubble to jump get up to hit backplate at the bottom of vehicle body, what then first hit is needle punched non-woven fabrics, due to the elasticity of needle punched non-woven fabrics, and the sound sent when the sound sent during backplate at the bottom of rubble bungee vehicle body can be significantly less than rubble bungee existing automotive engine guar plate.Meanwhile, backplate at the bottom of vehicle body described here not only can be used for automotive engine protection, also can be used for other structure of protecting bottom of automobile body.Therefore the utility model not only can provide actv. to protect to underbody structures such as automotivies engine, but also has the effect of sound insulation and noise reduction, and structure is simple simultaneously, and lightweight, processing and manufacturing cost is low.
As preferably, the upper surface of end panel reality is fixed with spunlace non-woven cloth.The same with needle punched non-woven fabrics, spunlace non-woven cloth is also fixed on the upper surface of smooth end panel reality in advance by cementing method, and then utilizes the method for mold pressing to make backplate at the bottom of vehicle body.This preferred version, can prevent backplate at the bottom of vehicle body from running car way, occurring vibrating noise because of backplate at the bottom of vehicle body and loosening of body bottom fixed connection structure, thus is conducive to improving experiencing by bus of driver and conductor.
As preferably, end panel reality is glass pricker plate.This preferred version, end panel reality is lightweight, has sound-absorbing, sound insulation, heat insulation, environmental protection, the feature such as fire-retardant, can improve the effect of the sound insulation and noise reduction of backplate at the bottom of vehicle body.
As preferably, at the bottom of vehicle body, backplate is provided with water falling hole.Wherein water falling hole is located at the lower concave part of backplate at the bottom of vehicle body usually.This preferred version, can prevent from seeping phenomenon appears in backplate at the bottom of vehicle body.
In sum, the beneficial effect that the utility model brings is: not only actv. can be provided to protect to underbody structures such as automotivies engine, but also has the effect of sound insulation and noise reduction, and structure is simple simultaneously, and processing and manufacturing cost is low.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the utility model cross section structure schematic diagram.
In figure: 1, end panel reality;
2, needle punched non-woven fabrics;
3, spunlace non-woven cloth;

Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Fig. 1 is the structural representation of end backplate on the left of auto body, and Fig. 2 is the cross section structure schematic diagram of backplate at the bottom of vehicle body.On the right side of auto body, the structure of end backplate is substantially identical with the structure of end backplate on the left of auto body, does not describe in detail at this.
As depicted in figs. 1 and 2, the utility model comprises end panel reality 1, the lower surface of end panel reality 1 is fixed with needle punched non-woven fabrics 2, the upper surface of end panel reality 1 is fixed with spunlace non-woven cloth 3, as preferably, end panel reality 1 is glass pricker plate, and backplate at the bottom of vehicle body is provided with some water falling holes 4.
The specific embodiment of the above is only the utility model preferably embodiment, not limits concrete practical range of the present utility model with this.The equivalence change that all shapes according to the utility model, structure are done ought to all be included in protection domain of the present utility model.
