The present invention provides a foldable electronic device comprising a central base, panel assemblies, and a scotch yoke synchronization module. The central base includes a base portion and a plate portion. Each panel assembly has a wing member pivoted to the base portion. The scotch yoke synchronization module includes a guide column, a liftable block, crank members, sliding yokes, and sliding pins. The guide column is on the plate portion, and the liftable block moves along it. Each crank member is pivoted to the base portion, with sliding yokes on the liftable block extending widthwise. Sliding pins on the crank members are accommodated in the sliding yokes for back-and-forth movement. When the liftable block moves along the guide column, the sliding pins slide in the yokes, causing the crank members to rotate in opposite directions simultaneously.

This application belongs to the field of internal combustion engine technology, and particularly relates to a Scottish yoke internal combustion engine, vehicles, ships, and aircraft. The Scottish yoke internal combustion engine includes: a crankshaft with at least one connecting rod journal; a connecting rod with a crankshaft connection portion having a sliding groove; a slider slidably disposed within the sliding groove; a first rolling bearing installed in a mounting hole of the slider, the connecting rod journal and the slider being rotatably connected via the first rolling bearing; and two second rolling bearings respectively installed on both sides of the slider along its sliding direction within the sliding groove, the slider being slidably mounted within the sliding groove via the two second rolling bearings. The technical solution of this application aims to solve the problem of dry friction wear between the bearing bush and connecting rod journal, and between the slider and connecting rod in a Scottish yoke internal combustion engine without forced lubrication.
