A shelf tray assembly has a bracket and a partition, where the partition includes a first partition. The bracket includes a sliding rail with a second section and a first section higher than the second section, and there is a first height difference between the first and second sections. The first partition is configured to reciprocate on the bracket along the sliding rail, and a movement path of the first partition includes a first position and a second position. When the first partition is located at the first position, the first partition is supported on the first section. When the first partition is located at the second position, the first partition is supported on the second section. The shelf tray assembly includes a lifting structure. A height difference when the first partition rises or falls can be effectively reduced, and a moving process of the first partition becomes smoother.
