Novel composite board for grid core vehicle
PendingCN121989517AGuaranteed structural strengthBrazing process is simpleSuperstructure subunitsMetal layered productsActivated carbonHoneycomb
The invention discloses a novel grid core composite board for a vehicle, and belongs to the technical field of automotive upholstery. The invention aims to solve the problem that an existing automobile floor is difficult to consider light weight, structural strength and sound insulation and purification functions at the same time. According to the technical scheme, the honeycomb aluminum plate is characterized by comprising a first aluminum plate body, a second aluminum plate body and a honeycomb core formed by clamping multiple sets of first battens and multiple sets of second battens; a plurality of first clamping grooves are formed in the lower walls of the first battens, a plurality of second clamping grooves are formed in the upper walls of the second battens, the first battens and the second battens are clamped to form a latticed honeycomb core, and a plurality of cavities are formed inside; the cavity can be selectively filled with sound insulation cotton, activated carbon particles or a combination of two layers of sound insulation cotton and activated carbon. The invention has the main beneficial effects that the structure is light and high in strength, the process is simple, multiple functions of sound insulation, air purification and the like can be integrated according to requirements, and the comprehensive performance of the automotive interior floor is obviously improved.
