Description

Technical Field

[0001] This utility model belongs to the technical field of interior panels for new energy vehicles, and specifically relates to a low thermal conductivity interior panel structure for new energy vehicles. Background Technology

[0002] New energy vehicles refer to automobiles that utilize unconventional fuels (or novel power systems) and integrate advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles, new technologies, and new structures. This is not only an important direction for the transformation and upgrading of the automotive industry but also a key measure to address the energy crisis and environmental pollution. New energy vehicles use battery packs as their power source, making battery thermal management a crucial aspect. Interior panels near the battery pack require special protection. Current technologies commonly use asbestos or ceramic fibers to reduce heat transfer; however, these materials do not meet environmental protection requirements, potentially exposing new energy vehicle occupants to a non-environmentally friendly environment for extended periods, thus posing health and safety issues.
