The instrument board of the vehicle is an assembly with various indication instruments, ignition switches and the like in a cab, and consists of various instruments, indicators, warning lamps for drivers, alarms and the like, provides the drivers with required automobile operation parameter information, and displays the automobile operation parameter information in a proper mode. Main driving side guard plates and auxiliary driving side glove boxes on the instrument board have the effect of protecting passengers when a whole automobile collides, have higher requirements on the strength of parts, have weaker strength when being directly processed by fibrilia materials, and cannot meet the performance requirements of the parts, in the embodiment, the fibrilia plates 1 and injection molding materials are subjected to injection molding together to obtain a plastic structure 2 for wrapping the periphery and the back of the fibrilia plates 1, and the plastic structure 2 is provided with a relatively dense and compact reinforcing rib structure, and the skin 3 is wrapped by utilizing a male mold vacuum adsorption process, so that the strength of the parts is improved, and the knee collision and the product rigidity requirements of the whole automobile are met.
The embodiment of the invention also provides a vehicle, which comprises the automobile instrument panel.
Although the invention is disclosed above, the scope of the invention is not limited thereto. Various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications will fall within the scope of the invention.
