Description
Technical field
The utility model relates to vehicle exterior cladding element structure technology, relates in particular to a kind of brace panel and vehicle exterior cladding element for conducting electricity.
Background technology
Along with the development of automotive technology, the continuous of automobile volume of production and marketing risen, and energy-saving and emission-reduction, lightweight become the inexorable trend of automobile industry development.In body structure, the application of the lightweight materials such as aluminum alloy, magnesium alloy, carbon fiber is also more and more.
In prior art, aluminium is applied often in the lightweight of vehicle exterior cladding element, such as full aluminium engine cover, aluminum bonnet, aluminum side door etc., inner panel and outside plate that general outer covering piece comprises all adopt aluminum alloy materials, compare steel outer covering piece loss of weight in a large number.
And magnesium is as metal the lightest in common metal, its fusing point and aluminium are close, and density is only 2/3 of aluminium, the strength-to-density ratio of magnesium alloy will be higher than aluminum alloy and steel, stiffness-to-density ratio and aluminum alloy and steel are suitable, can bear larger load, and it has dimensional stability and good welding performance.Along with weight-saving gos deep into, the application of magnesium alloy in outer covering piece is also necessary.But because magnesium alloy belongs to more active metal, its antiseptic property is relatively poor.
In automobile electrophoresis process, need to, by the whole access of vehicle body sheet metal electrode, for guaranteeing electrophoresis quality, need to guarantee that all panel beatings all conduct electricity.If certain part is insulated material, isolate, this part can cause electrophoresis insufficient due to the reason that cannot conduct electricity, thereby has corrosion risk.The outer covering piece of ordinary steel material/alumina based material, due to steel material and alumina based material electric conductivity fine, as long as having contact just can conduct electricity, therefore its conduction can be delivered to hinge by vehicle body, from hinge, be delivered to outer covering piece inner panel again, by outer covering piece inner panel, be delivered to outside plate again, guarantee that all parts of outer covering piece all conduct electricity, therefore do not have the obstructed problem of conduction.And for the inner panel of magnesium alloy, because magnesium metal is relatively active, need to before crossing electrophoresis, first do anti-corrosion treatment, and its preservative coat often electric conductivity not good enough even conduction, therefore when electricity is led after hinge, because thereby inner panel has the conduction that preservative coat has interrupted arriving outside plate, cause outside plate to be isolated, have the inadequate problem of electrophoresis.
In existing technical scheme, also there is no relevant structure solution, but increase loop by online frock, Ji paint shop is the conductor wire with chuck by online increase two, one end is clamped on vehicle body, the other end is clamped on the outside plate of outer covering piece, to guarantee that electrode is imported to outside plate, until remove again after complete electrophoresis.This online scheme can solve conduction problem, but the shortcoming existing is: 1) for the position being held on vehicle body and outside plate, owing to lacking electrophoresis, still have corrosion risk; 2) be difficult to find suitable clip position on outside plate, often needing has certain requirement so that suitable position to be provided to the moulding of outside plate, therefore the moulding of outside plate is had to certain limitation.
