Patent ID: 11008182

Abstract:
A rotatable tray mechanism includes a base, a rotatable tray, and a revolute pair assembly and an actuating unit arranged between the base and the rotatable tray. At least one of the rotatable tray and the base includes a revolving shaft arranged on at least one edge. The revolute pair assembly is arranged on at least one of the base and the rotatable tray and is at a location opposite to the revolving shaft. One revolving shaft mates with at least one revolute pair assembly including a revolute pair and an enable mechanism, wherein the revolute pair has a first state and a second state. The enable mechanism is enabling the revolute pair to switch over between the first state and the second state. When the revolute pair is in the first state, the rotatable tray rotates with respect to the base by taking the revolving shaft as a rotating shaft and taking the revolute pair as support of the revolving shaft when the actuating unit applies an acting force, wherein the direction of the acting force applying the rotatable tray is a direction far away from the base.
