Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
Example 1
As shown in fig. 1 to 3, an inner door panel for an automobile, includes: a first functional part 110, a second functional part 120, a connecting part 130, and an external appearance part 200.
Wherein the inner door panel body 100 is provided as a continuous fiber reinforced thermoplastic composite, and the exterior part 200 is provided around the inner door panel body 100 and forms a semi-enclosed structure.
In the present embodiment, the inner door panel body 100 is provided as a carbon fiber reinforced thermoplastic composite and the outer appearance portion 200 is provided to surround the same to form a semi-surrounding structure, thereby reducing the thermal expansion coefficient, increasing the strength, and reducing the production cost and the product weight.
As shown in fig. 1 to 3, in addition to the above embodiments, the appearance part 200 is provided as a continuous fiber reinforced thermoplastic composite, and the surface of the appearance part 200 has a dermatoglyph.
The general automobile inner door plate is wrapped by leather, the wrapped leather needs to be subjected to secondary processing after injection molding, the process is complex, the cost is high, and the leather made of polyvinyl chloride can emit pungent smell to pollute the air in the automobile.
In this embodiment, the exterior part 200 is formed as a carbon fiber reinforced thermoplastic composite member having a skin grain on the surface thereof, and the inner door panel body 100 and the exterior part 200 are integrally molded without secondary processing, so that air in the vehicle is not polluted.
Example 2
As shown in fig. 4 to 6, the exterior part 200 is formed as a polypropylene member, unlike embodiment 1.
In the present embodiment, the inner door panel body 100 and the design portion 200 are integrally molded by die-casting, and the design portion 200 made of a polypropylene material does not need to be skin-textured.
Example 3
As shown in fig. 7 and 8, unlike embodiment 1, the inner door panel body 100 is provided in a separate manner, specifically, the inner door panel body 100 includes a first functional portion 110, a second functional portion 120, and a connecting portion 130, the first functional portion 110 and the second functional portion 120 are provided in a left-right correspondence, the first functional portion 110 is connected to the second functional portion 120 through the connecting portion 130, both the first functional portion 110 and the second functional portion 120 are provided as a continuous fiber reinforced thermoplastic composite, and the connecting portion 130 is provided as a polypropylene member.
Specifically, because a hinge, a stopper and a door lock need to be installed, the first functional part 110 and the second functional part 120 need higher strength, at least the first functional part 110 and the second functional part 120 are made of carbon fiber reinforced thermoplastic composite, the connecting part 130 is located between the first functional part 110 and the second functional part 120, the first functional part 110 and the second functional part 120 are connected through the connecting part 130, and the connecting part 130 is used for the first functional part 110 and the second functional part 120, which has lower strength requirement.
As shown in fig. 7 and 8, in addition to the above embodiment, the external appearance part 200 is formed of a polypropylene material and is joined to the connecting part 130 to form a structure of a chevron shape.
In the specific manufacturing process, the difficulty of directly integrally molding the first functional part 110, the second functional part 120 and the connecting part 130 is large, so the first functional part 110 and the second functional part 120 can be molded separately, and then the connecting part 130 and the appearance part 200 are injection molded.
In the present embodiment, the manufacturing process of molding the first and second functional parts 110 and 120 separately and then injection molding the connecting part 130 and the external appearance part 200 is relatively simple and requires relatively low manufacturing requirements, which is convenient to implement.
As shown in fig. 7 and 8, in the above-described embodiment, the connecting portion 130 is further provided with the rib 300 in the above-described automobile inner door panel.
In the present embodiment, the connection portion 130 is further provided with a reinforcing rib 300 in consideration of the rigidity and strength of the entire inner door panel.
