Description
Technical field
Automobile body accessories manufacturing technology field is the utility model is related to, more particularly to a kind of lightweight automobile engine cover.
Background technology
In automotive field, the lightweight of automobile is to save one of the energy, the important way for reducing discharge.The light weight of automobile
Change can improve dynamic property, economy, security by way of reducing automobile own wt and reduce exhaust emissions etc., come
Reach the purpose of energy-saving and environmental protection, and action effect is clearly.Automotive light weight technology, it is exactly to ensure automobile intensity and security
On the premise of energy, the complete vehicle quality of automobile is reduced as much as possible, and then improves the combination properties such as the dynamic property of automobile, security,
So as to reach the purpose of energy-saving and emission-reduction.
Automobile engine cover is the important component of automobile, and it had both played air conducting effect, protected engine and week again
Side pipe fittings etc., can also be substantially prevented from the adverse effect such as impact, burn into rainwater and electrical interference, and it is general in structure
It is made up of outside plate and inner panel, inner panel plays a part of strengthen rigidity, belongs to a kind of skeleton construction.
The main path of body lightening is generally divided into three aspects:Using Novel lightweight material, automotive body structure
Design optimization and advanced manufacturing forming process and interconnection technique.
Composite is generally made up of two kinds of combination of materials:Reinforcing material and matrix material.Reinforcing material can
Greatly increase the rigidity and intensity of matrix material；Matrix material is that reinforcing material bonds together, and protects reinforcing material, is transmitted
Load and the extension for hindering crackle.Reinforcing material is often threadiness, and composite has light weight, and intensity is high, and vibration damping insulates against sound,
Impact resistance, Resisting fractre toughness, fatigue resistance are good, are not easy the advantages that burn into is non-aging, and designability is good, and easy processing shapes.This
A little advantages cause composite also gradually to be found application in automotive field, and with the development of technology, composite is in the car
Utilization ratio will be increasing.
In general bonnet is internal all by being directly welded after two formed by stamping thin steel plate in the prior art
Steel plate is frequently with there is substantial amounts of cellular hollow out to realize lightweight.It is often each in the prior art to ensure the rigidity of bonnet
Sheet metal component has certain thickness, and cost is of a relatively high, and the quality of vehicle is also heavier, and the oil consumption economy to vehicle causes one
It is fixing to ring.
Auto parts and components are made using plastics and its composite, opposing metallic material has lightweight, and (density only has steel
The 1/6-1/7 of material density), the significant advantage such as the low, easy processing of cost, wherein most widely used is fibre reinforced composites.
And as SMC products, GMT products have, production efficiency is high, cost is low, easily returns relative to other fibre reinforced materials for LFT-D products
The advantages such as regeneration, product are lighter, performance is strong are received, gradually substitutes SMC and GMT, turns into current automotive industry fiber-reinforced composite material
The developing direction of material.
The utility model researches and develops a kind of lightweight automobile engine cover, and advanced composite material (ACM) one is used by LFT-D production lines
Body formed its outside plate of manufacture and inner panel, compared to metal plate bonnet, have saved cost, effective to mitigate vehicle body overall weight, from
And reach the purpose for reducing oil consumption, saving the energy.
