A foot ring structure includes a space defined by a space between an inner ring surface and an outer ring surface, and a top surface and a bottom surface are respectively located on opposite sides of the inner ring surface and the outer ring surface, and a plurality of pins are installed on the outer ring surface to provide power Input and / or data transmission purposes. Since the electronic components inside the foot ring are arranged adjacent to the ring-shaped surface, and the pins are arranged on the surface of the outer ring, the overall structure of the foot ring can be miniaturized.一種腳環結構，包含相間隔的內環表面與外環表面界定容室，以及頂面與底面分別位於內環表面與外環表面相對二側，並於外環表面安裝複數個接腳提供電力輸入及/或資料傳輸用途。由於腳環內部的電子元件設置於鄰近環型表面，搭配將接腳設置於外環表面，可以使得腳環結構整體進行微型化。
