The invention relates to the technical field of automobile accessories, and provides an electrifying device for a multimedia automobile headrest, a headrest assembly and an automobile, and the electrifying device comprises a playing device arranged in the automobile headrest; the headrest supporting rod is inserted into the automobile headrest; the power connection assembly is arranged on the headrest supporting rod, the power connection assembly is provided with a power connection piece connected to the headrest supporting rod in an embedded mode, one end of the power connection piece is electrically connected to the playing device, and the power connection piece can supply power to the playing device when a power source is switched on and is disconnected with the power source when the automobile headrest is separated from the automobile seat. The part, connected to the supporting rod in an embedded mode, of the power connection piece has an expansion state, and the power connection piece is tightly attached to the inner wall of the supporting rod in the expansion state, so that the stability of connection between the power connection piece and the supporting rod is enhanced. And the requirement of drilling threaded holes or reserving holes with specific sizes on the headrest support rod is avoided, so that the processing flow of the headrest support rod is greatly simplified.

    本发明涉及汽车配件技术领域,提供一种用于多媒体汽车头枕的通电装置、头枕组件及汽车,包括:播放装置,其设置在汽车头枕内;头枕支杆,其插设在汽车头枕上;接电组件,其设置在头枕支杆上,接电组件具有嵌接在头枕支杆上的接电件,接电件的一端电连接在播放装置上,接电件可在接通电源时为播放装置供电,并在汽车头枕与汽车座椅分离时与电源断开连接,用以不干涉汽车头枕与汽车座椅的分离,接电件嵌接在支杆上的部分具有膨胀状态,接电件通过膨胀状态与支撑杆内壁紧密贴合,以此强化二者连接的稳固性,这种方式的优势在于,免去了在头枕支杆上开凿螺纹孔或预留特定尺寸孔洞的需求,从而大幅简化了头枕支杆的加工流程。
