Problems solved by technology

[0002] Automobile panels often use laminates made of continuous fiber reinforced composite materials (such as carbon fiber). Due to the characteristics of the material and the characteristics of the molding process, they cannot be assembled by folding the inner and outer panels like the traditional sheet metal panels. The general method is to glue the inner and outer panels. Connected, the edge forms a straight edge, which cannot meet the requirements of the shape
In order to achieve edge rounding, the general method is to machine or grind the inner and outer panels into rounded corners after bonding, which will cause the edges of the conforming materials to be directly exposed to the environment, which will be corroded or damaged, which will cause problems such as delamination

Embodiment 1

[0063] This embodiment provides the manufacturing method of automobile outer cover, please refer to Figure 3a to Figure 3e .

[0064] First, see Figure 3a , forming a composite material laminated outer panel 1 . The outer panel 1 includes an outer panel 11 and an inner panel 12 formed on the outer panel 11 . Therein, the edge portion 11' of the outer panel 11 protrudes beyond the edge portion 12' of the inner panel 12. This structure can also be formed by removing the inner panel 12 on the edge portion 11' of the outer panel 11.

[0065] Then, see Figure 3b and Figure 3c , the edge portion 11 ′ of the outer panel 11 beyond the edge portion 12 ′ of the inner panel 12 is turned toward the inside of the outer panel 12, that is, the edge portion 11 ′ of the outer panel 11 is performed 180° around the edge portion 12 ′ of the inner panel 12 Fold over until the upper surface of the edge portion 11 ′ of the outer panel 11 fits the upper surface of the edge portion 12 ′ of t...

Embodiment 2

[0073] In this embodiment, on the basis of the manufacturing method for making an automobile outer covering in Embodiment 1, another manufacturing method suitable for an automobile outer covering is further provided. For details, see Figure 4a to Figure 4f .

[0074] First, if Figure 4a As shown, a composite material laminated outer panel 1 is formed. The outer panel 1 includes an outer panel 11 and an inner panel 12 formed on the outer panel 11 . Therein, the edge portion 11' of the outer panel 11 protrudes beyond the edge portion 12' of the inner panel 12. This structure can also be formed by removing the inner panel 12 on the edge portion 11' of the outer panel 11.

[0075] Then, see Figure 4b and Figure 4c As shown, the edge portion 11 ′ of the outer panel 11 beyond the edge portion 12 ′ of the inner panel 12 is folded toward the inside of the outer panel 12 , that is, the edge portion 11 ′ of the outer panel 11 is folded around the edge portion 12 ′ of the inner ...

Abstract

The invention discloses a manufacturing method of an automobile outer covering part. The manufacturing method comprises the steps that a composite material laminating outer plate is formed, the edge part of the outer plate is folded toward the interior of the outer plate till the upper surface of the edge part of the outer plate is attached to the upper surface of the interior of the outer plate so as to form a folding part, and the outer side edge of the folding part forms a round angle; and a composite material laminating inner plate is formed, the upper surface of the composite material laminating outer plate are attached to the position, close to the inner side edge of the folding part, of the composite material laminating inner plate, the upper surface of the inner plate is parallel and level to the upper surface of the folding part, and the space between the edge of the inner plate and the inner side edge of the folding part is filled with binding agents. The edge part of the outer plate is folded inward to form the folding part, not only is the round angle formed in the outer side edge of the folding part, but also the edge part of the inner plate is closed by combining the inner side edge of the folding part with the inner plate.
