Problems solved by technology
However, after using fiber reinforced composite materials, the metal lock can not be welded to the carbon fiber sandwich panel, and the traditional connection method can no longer meet the needs of new applications. Therefore, it is necessary to propose a new connection and installation method between the cover and its accessories. In order to facilitate the further promotion and application of fiber reinforced composite materials in the automotive industry

The invention discloses a fiber reinforced composite material sandwich panel structure with a lock catch. The structure comprises a sandwich panel made from a fiber reinforced composite material, an embedded part pre-buried in the sandwich panel, a lock catch base arranged outside the sandwich panel and detachably connected to the embedded part and the lock catch mounted on the lock catch base. Under the circumstance of no welding, the lock catch still can be mounted and fixed to the fiber reinforced composite material sandwich panel structure, certain connecting strength is ensured, and the locking demands on covering parts of automobiles in different working conditions are met.
Description
technical field [0001] The invention relates to a closure with a lock, in particular to a fiber-reinforced composite material sandwich panel structure with a lock, which can be applied to engine covers, doors, tailgates, etc. closures. Background technique [0002] In recent years, with the gradual increase of car ownership, the resulting climate change problem has become more and more serious. Both the country and the car manufacturers have realized the importance of environmental protection and rational use of energy. For the automobile industry, especially when all countries are vigorously developing new energy vehicles, the realization of automobile lightweight has become the only way for the sustainable development of the industry. Due to its excellent comprehensive performance, carbon fiber composite materials have been placed with high expectations on the road to lightweight vehicles. Compared with the high-strength steel and aluminum alloy materials currently used ...
