Synchronizing mechanism, hinge device, folding device and foldable electronic equipment

The invention provides a synchronizing mechanism, a hinge device, a folding device and foldable electronic equipment, the synchronizing mechanism comprises a fixed seat, a sliding seat, a first swing arm and a second swing arm arranged on two sides of the fixed seat, and a synchronizing part arranged between the first swing arm and the second swing arm, when one swing arm rotates, the synchronizing part slides along a first direction, and when the other swing arm rotates, the synchronizing part slides along a second direction; and the other swing arm is driven to rotate. Each swing arm comprises two sub swing arms which are arranged in the first direction and have a gap, and the synchronous part is pressed between the two sub swing arms of each swing arm in the first direction. First sliding structures are arranged between the two sub-swing arms and the sliding seat and between the two sub-swing arms and the fixed seat, and a second sliding structure is arranged between at least one sub-swing arm and the synchronous piece or the fixed seat to limit the sub-swing arm where the second sliding structure is located to move relative to the fixed seat in the third direction. According to the synchronous transmission device, the problem that the synchronous part is prone to inclining and warping can be effectively solved, high-precision synchronous transmission is achieved, a good synchronous effect is achieved, and flatness is guaranteed.
