Definitions
- the present invention relates to a dissimilar panel structure.
- Vehicles such as automobiles are required to reduce the weight of the vehicle body in order to improve running performance, operability, or fuel consumption. For this reason, in various automobile body parts, instead of conventional steel materials, materials having a low specific gravity such as aluminum alloys have begun to be applied.
- automobile panel structures such as hoods (bonnets), doors, and trunks are hollow structures composed of an outer panel (outer plate) and an inner panel (inner plate). The material of these panels is aluminum. Use of alloy materials is under consideration.
- both the outer panel and the inner panel can be changed to an aluminum alloy plate, but it is also possible to form a dissimilar panel structure in which materials having characteristics according to the required characteristics of each panel are combined with each other.
- an outer panel that is required to have design, lightness, impact energy absorption, etc. is formed of an aluminum alloy plate
- an inner panel having a complicated shape and a deep forming depth is a steel plate with excellent formability. It is possible to form with.
- an adhesive layer that also serves as an insulating layer for preventing electrolytic corrosion is usually formed between the outer panel and the inner panel by a thermosetting resin such as an epoxy resin, a polyester resin, or a phenol resin. Resin layer).
- Patent Document 1 a method of spot welding a steel rivet punched from the aluminum alloy plate and the steel plate has been proposed.
- the method of providing the protruding part which protrudes in the outer plate side in the inner plate is proposed (refer patent document 2).
