[0024] According to the first aspect of the present application, an embodiment of the present application provides a method for manufacturing a concept car, combining Figure 1 and Figure 2, the manufacturing method includes: obtaining a mass-produced car sheet metal platform; modifying the mass-produced car sheet metal platform to obtain a concept car sheet metal platform; manufacturing a body of the concept car, connecting the body to the concept car sheet metal platform, and obtaining a concept car, wherein the body is composed of a combination of carbon fiber parts, the carbon fiber parts include a carbon fiber material part and present the external shape of the carbon fiber parts through the carbon fiber material part, and the carbon fiber parts also include a reinforcing skeleton connected to the carbon fiber material part, and the reinforcing skeleton is connected to the concept car sheet metal platform. It can be understood that the connection between the reinforcing skeleton and the concept car sheet metal platform refers to the connection of a part of the reinforcing skeleton to the concept car sheet metal platform to achieve the connection between the body and the concept car sheet metal platform. In addition, the reinforcing skeletons of different carbon fiber parts can also be connected. It should also be noted that in this application, the carbon fiber parts present the external shape of the carbon fiber parts through the carbon fiber material part, which means that when the concept car is completed, the external shape of the carbon fiber parts is presented by the carbon fiber material part, and the external shape of the carbon fiber parts refers to the shape that the carbon fiber parts are expected to show in the concept car, excluding the parts that are hidden and do not need to be shown after the concept car is completed. In this embodiment, the sheet metal platform of the mass-produced vehicle can be the sheet metal platform of the vehicle that has been mass-produced. The sheet metal platform can be the bottom platform and auxiliary structure of the vehicle's body-in-white, which is usually made by sheet metal processing technology. In this embodiment, the body part is made by replacing the sheet metal in the relevant technology with carbon fiber parts. When the carbon fiber parts are combined, the combination can be achieved by connecting the reinforcing skeletons between different carbon fiber parts. The carbon fiber material part in the carbon fiber parts can be processed by vacuum induction technology to reflect the new shape of the concept car. The reinforcing skeleton can be connected and fixed with the carbon fiber material part by resin and fiber cloth after coating. The reinforcing skeleton can improve the strength of the carbon fiber material part, thereby meeting the use requirements of the concept car. This application completes the rapid trial production of the body by combining the reinforcing skeleton with the carbon fiber sample, reflecting the new shape while meeting the stiffness & strength requirements. The reinforcing skeleton is connected to the sheet metal platform of the concept car, so that the external load can be borne by the reinforcing skeleton, reducing the strength requirements of the carbon fiber material part, and facilitating processing. When making a concept car, it is also possible to further include setting interior and exterior covering parts in the concept car. The interior and exterior covering parts of the concept car can be made using rapid prototyping processes such as 3D printing, CNC milling, and silicone molds. The connection methods can be flexibly selected from screw connection, snap connection, magnet, bonding, and the like.
[0025] The manufacturing method of the concept car provided in the embodiment of the present application uses the sheet metal platform of a mass-produced car to transform and manufacture the sheet metal platform of the concept car, which can simplify the manufacturing process and manufacturing cost of the sheet metal platform of the concept car with the help of the parts of the mass-produced car. At the same time, the body part is composed of a combination of carbon fiber parts with a reinforced frame. While ensuring the strength of the concept car by strengthening the frame, the body shape can be manufactured through carbon fiber molding technology, without the need to additionally manufacture complex and precise sheet metal molds and injection molds, further shortening the production cycle and reducing production costs.
