The application provides a rotating mechanism and a foldable electronic device. The rotating mechanism comprises a connecting piece, a first swing arm, a stop sliding piece and a stop elastic piece. The first swing arm comprises a guide sliding rod. The guide sliding rod, the stop sliding piece and the stop elastic piece are arranged on the connecting piece. In a first direction, the guide sliding rod, the stop sliding piece and the stop elastic piece are arranged in sequence. The stop sliding piece is provided with a stop concave-convex end. The stop elastic piece extrudes the stop sliding piece, so that the stop concave-convex end can abut against the guide sliding rod. The stop concave-convex end comprises a first convex part, a stop concave part and a second convex part. In a second direction, the first convex part, the stop concave part and the second convex part are connected in sequence. The guide sliding rod can move in the second direction to abut against the first convex part, the stop concave part or the second convex part. When the guide sliding rod abuts against the stop concave part, the first swing arm is stationary relative to the connecting piece, so that the rotating mechanism is in a first state. The guide sliding rod and the stop concave part have a simple cooperation structure, and the rotating mechanism can maintain a stable first state.

This application provides a damping shaft structure and electronic device. The damping shaft structure includes a base, a wall portion, a receiving space with one open end formed by the wall portion, an arc-shaped guide rail disposed on the wall portion and extending from the opening into the receiving space, and a damping medium housed in the receiving space; a rotating member, at least partially housed in the receiving space and in contact with the damping medium, including a rotating guide rail engaged with the arc-shaped guide rail, and the rotating member is used to rotate about a rotation center along the arc-shaped guide rail; the rotation center is located on the outer side of the rotating member away from the receiving space. The damping shaft structure and electronic device provided in this application at least solve the problem of poor overall integrity in the prior art.

Double-sided luggage carrier for a moped for attaching panniers, wherein the double-sided luggage carrier comprises two triangularly shaped support surfaces (1) and the connection of the support surfaces (1) is made via a bridge structure (2) which has two rearwardly angled front connecting elements (3a, 3b) and two rear connecting elements (4a, 4b) angled forwards in the direction of travel and the front connecting elements (3a, 3b) are connected to each other via a rail (6) attached to the frame (5) of the moped.
