The invention discloses a thin-film spacecraft, which comprises communication electronic equipment, a star body, a cylinder body, a longitudinal telescopic mechanism, at least one thin-film antenna structure and a wrapping structure, and is characterized in that an opening is formed in one side of the star body; the cylinder body is located at the opening and connected with a star body, and a center hole of the cylinder body is communicated with the opening; one end of the longitudinal telescopic mechanism is connected into the star body, and the other end of the longitudinal telescopic mechanism is connected with the communication electronic equipment so as to drive the communication electronic equipment to retract into the star body or extend out of the barrel; the thin film antenna structure is connected with the communication electronic equipment, the longitudinal telescopic mechanism and the cylinder body so as to stretch out and draw back along with the longitudinal telescopic mechanism; the wrapping structure is arranged on the longitudinal telescopic mechanism and located on the side, away from the star body, of the communication electronic equipment. According to the invention, one part of the longitudinal telescoping mechanism is contracted into the star body, and the thin film antenna structure is driven to be folded and folded along the length direction and then coiled and folded between the wrapping structure and the cylinder body, so that the space occupied by the folded thin film antenna structure on the star body is reduced.
本发明公开了一种薄膜航天器,包括通信电子设备、星体、筒体、纵向伸缩机构、至少一薄膜天线结构以及包拢结构,星体的一侧设有开口;筒体位于开口处,并与星体相连接,筒体的中心孔与开口连通;纵向伸缩机构的一端连接于星体内,另一端与通信电子设备连接,以带动通信电子设备收缩至星体内或伸展至筒体外;薄膜天线结构分别与通信电子设备、纵向伸缩机构和筒体相连接,以随纵向伸缩机构伸缩;包拢结构设置在纵向伸缩机构上,并位于通信电子设备远离星体的一侧。本发明通过将纵向伸缩机构的一部分收缩至星体内,带动薄膜天线结构沿长度方向折叠收拢后,并盘绕收拢在包拢结构与筒体之间,以缩小收拢后的薄膜天线结构在星体上占据的空间。
