Traditional roof structures are usually composed of metal outer panels and inner panels. Although they have high structural strength, they are heavy and cannot meet the lightweight requirements. In addition, the sound insulation and heat insulation effects are poor, resulting in low overall performance of the roof. Therefore, developing a new type of roof assembly structure to overcome the shortcomings of existing technologies has become an important research direction in the current automotive industry.

[0003] In view of the above-mentioned related technologies, in order to solve the problem of requiring lightweight while also requiring sound insulation and heat insulation, a roof assembly with a composite sandwich structure is proposed. Summary of the Invention

During the manufacturing process, rubber pads and high-performance foam plastics are stacked and fixed between the outer roof and the roof to form an intermediate layer. The intermediate layer plays a role in shock absorption, sound insulation and heat insulation, improving the comfort and performance of the roof assembly. The composite multi-layer structure has good shock absorption, sound insulation and heat insulation effects while maintaining light weight and high strength. 2. During the manufacturing process of the middle layer, vibration sensors, temperature sensors, pressure sensors, a data processing unit, and a wireless communication module are integrated into it, and electrical connections between the various components are ensured. The intelligent sensor network is used to monitor the vibration, temperature, and pressure of the roof assembly in real time, and transmit the data to the vehicle control system for intelligent management. During the manufacturing process of the middle layer, the data processing unit is integrated into it and connected to the wireless communication module and the vehicle control system through electrical lines. The data processing unit is responsible for receiving, processing, and analyzing the data transmitted by the sensors, and communicating with the vehicle control system through the wireless communication module to achieve real-time data transmission and sharing. The wireless communication module also exchanges signals with the outside world. When violent vibration, abnormally high temperature, and high pressure on the roof are detected, the vehicle alarm is automatically triggered and a signal is sent to the outside world to alert and request assistance. This allows the middle layer to provide various vehicle data at the time while improving performance and automatically trigger the alarm system to improve safety. 3. During the manufacturing process of the roof, the roof surface layer and the top body are designed and manufactured separately, and then the two are combined through a fixed connection. The roof surface layer provides decorative effects, and the top body provides structural support and strength. During the manufacturing process of the roof surface layer, microfiber materials are selected for processing and molding. Microfiber materials have good decorative effects and tactile properties, improving the aesthetics and ride comfort of the vehicle interior.
