[0002] With the rapid development of the automotive industry, consumers are increasingly demanding higher levels of functionality, safety, and comfort from car interiors. As a crucial component of the automotive interior, door interior components not only need to possess strong structural integrity to ensure safe use, but also need to integrate multiple functions such as armrests, storage, and audio systems to meet the daily needs of drivers and passengers.

[0003] Existing automotive door interior trim components are mostly made of a single material, resulting in insufficient strength and susceptibility to deformation, leading to loosening or damage after prolonged use. Furthermore, some interior trim components have illogical functional layouts; the armrest and storage space designs lack ergonomics, impacting the user experience. Speaker installation structures are rudimentary, prone to resonance noise, and offer poor protection. In addition, the complex installation structure of traditional interior trim components results in low assembly efficiency, making it difficult to meet the demands of mass production.

[0004] Therefore, there is an urgent need for a type of automotive door interior trim that is high in strength, highly integrated in function, stable in installation, and easy to use, in order to solve the aforementioned problems in the existing technology. Utility Model Content
