Abstract:
An anti-collision interface device and an intelligent blackboard. The anti-collision interface device comprises a housing (101), a connection terminal assembly (130), a cover plate (170), and a rotating shaft assembly, wherein the rotating shaft assembly comprises a first rotating shaft (181), an elastic abutting member (110), and a rotating member (120); the cover plate is rotatably connected to the connection terminal assembly by means of the first rotating shaft to close or open an opening (140); the rotating member is connected to the cover plate, and is arranged opposite the elastic abutting member; the elastic abutting member elastically abuts against the rotating member, one of the elastic abutting member and the rotating member is provided with an end face cam curved surface (190), and the other one thereof is provided with an abutting portion (123); the abutting portion abuts against the end face cam curved surface; and the end face cam curved surface is provided with a peak and two operating curved surface sections located on two sides of the peak. During the process of the cover plate rotating relative to the connection terminal assembly, an abutting position of the abutting portion and the end face cam curved surface is correspondingly changed, such that the elastic abutting member generates forces of different magnitudes on the rotating member to facilitate a user in completing an opening or closing operation, and the reliability is relatively high.
