Abstract
The invention relate to a component of an automobile, in particular to a light trunk lid of an automobile. The light trunk lid comprises an inner trunk lid plate and an outer trunk lid plate. Hinge mounting positions and a lock mounting position are arranged on the plate surface of the inner trunk lid plate and are close to the outer edge of the inner trunk lid plate, liquid aluminum is integrally molded to form the inner trunk lid plate, and the outer trunk lid plate is made of steel plates. The light trunk lid of the automobile has the advantages that the inner trunk lid plate is made of aluminum materials, so that the trunk lid is lightened; reinforcement plates can be omitted, accordingly, manufacturing and assembling processes are simple, the mounting precision can be improved, the development cost can be saved, and the fuel economy can be enhanced.
Description
Technical field
The present invention relates to a kind of automobile component, be specially a kind of lightweight Luggage Hold Cover.
Background technology
Car is generally made up of boot-lid inner panel branch unit and luggage-boot lid outside plate, and traditional boot-lid inner panel branch unit is generally made up of boot-lid inner panel, hinge stiffening plate and lock brace panel, between each, is fixed into an entirety by the form of welding.The parts of tradition boot-lid inner panel branch unit all obtain steel component in steel thin plate stretch pressing mode, and the formation of traditional luggage-boot lid branch unit need to accumulate all part production tolerances, welding tolerance, and existing deficiency is:
1) amount of parts is more, and the attendant equipments such as corresponding mould, cubing, fixture are more, processing and fabricating complexity, and productive costs is high;
2) Combination Welding of many, can affect the setting accuracy of luggage-boot lid annex;
3) luggage-boot lid assembly weight is heavier, is unfavorable for the raising of fuel economy.
Summary of the invention
The object of the invention is to, for the deficiencies in the prior art, provide a kind of lightweight Luggage Hold Cover, reduce Luggage Hold Cover weight, meanwhile, manufacture and assembling process are simple, improve setting accuracy.
Technical scheme of the present invention is, a kind of lightweight Luggage Hold Cover, comprise boot-lid inner panel and luggage-boot lid outside plate, and He Suo installation position, hinge installation position is set on the plate face near outer edge at boot-lid inner panel, described boot-lid panel inner panel is that liquid aluminium is one-body molded, and luggage-boot lid outside plate is steel plate.
Boot-lid inner panel is by the disposable punch forming of liquid aluminium, because of boot-lid inner panel overall depth dark, and the thick region of material such as have not, so need to use liquid aluminium punch forming, and luggage-boot lid outside plate is formed by steel plate punched, shallow because of outside plate press depth, can meet the forming requirements of steel plate by general Sheet Metal Forming Technology.
The density of aluminium is only 2/3 of steel, and whole processing and manufacturing process is simple, saves development cost, improves fuel-economy type.
The plate face thickness of the He Suo installation position, hinge installation position of described boot-lid inner panel is greater than the thickness of all the other plate faces of boot-lid inner panel, has omitted brace panel, reduces the difficulty of processing and manufacturing process.
Described boot-lid inner panel is connected by laser welding with the respective panels face of luggage-boot lid outside plate.
The present invention is a kind of lightweight Luggage Hold Cover, by adopting the material of aluminium as boot-lid inner panel, reduces luggage-boot lid weight, meanwhile, omitted brace panel, manufacture and assembling process are simple, improve setting accuracy, save development cost, improve fuel-economy type.
