Description

Technical Field

[0001] This utility model belongs to the field of automotive instrument panel crossbeam technology, specifically, it relates to a platform-based and modular composite instrument panel crossbeam device. Background Technology

[0002] The dashboard crossbeam assembly is usually connected to the car body. It supports the car's steering system, air conditioning system, electrical system, and passenger airbag system. It is one of the more important structural components in a car and a key component to ensure the car's driving quality and driving safety. The dashboard crossbeam assembly has a complex structure. If the design is not reasonable, it will cause the steering system and the entire dashboard system to vibrate and make abnormal noises during the car's operation, affecting the driver's operation and experience.

[0003] With the steady advancement of the "dual carbon" policy, automotive lightweighting technology is receiving increasing attention. The use of lightweight composite materials can give products excellent structural performance and outstanding weight reduction effects. When applied to fuel vehicles, it can reduce fuel consumption and emissions. When applied to new energy vehicles, it can improve driving range, be environmentally friendly and energy-saving, and reduce customers' range anxiety. Therefore, the application of composite material dashboard beams is gradually gaining favor among OEMs.

[0004] Although composite instrument panel crossbeams are gradually gaining favor among OEMs, the mold structure and process requirements for composite instrument panel crossbeams are relatively high. Furthermore, the addition of glass fiber materials to the composite material enhances structural performance, leading to deformation issues during manufacturing. Multiple pre-deformation analyses and mold adjustments are necessary to meet manufacturing precision requirements. Analysis and calculations show that composite instrument panel crossbeams currently suffer from higher mold development costs, longer development cycles, and higher unit costs compared to traditional steel and aluminum instrument panel crossbeams. In China's increasingly demanding automotive industry, which prioritizes rapid development, rapid manufacturing, low cost, and high quality, these composite instrument panel crossbeams are finding it increasingly difficult to meet customer needs. Therefore, a modular, platform-based composite instrument panel crossbeam device is needed to meet market demands with low cost, high quality, short lead times, and multi-model compatibility on the same platform.
