The operation of the tray 30 of the electronic device 100 according to the embodiment of the present application will be described in detail with reference to the following embodiments.

When the electronic device 100 is used, the flexible screen 20 needs to be folded to be convenient for storage. At which time the hinge assembly 10 begins to rotate about the center of rotation. At this time, according to the characteristics of the flexible screen 20, the flexible screen 20 starts to be folded inwards to form a protrusion, and the generated inner protrusion is lower than the horizontal position of the original flexible screen 20 which is flattened, so that interference with the position of the supporting plate 30 is caused. At this time, the first mating member 41 and the second mating member 42 are mated with each other to drive the tray 30 to move downward to the second position 34, avoiding interference with the folded-in convex surface of the flexible screen 20.

When the foldable electronic device is folded, the N-grade magnet or the iron block capable of being adsorbed is placed on the supporting plate 30 by means of the characteristic that north and south poles of the magnet are mutually attracted, the electromagnet is placed on the hinge assembly 10, the lead wire is connected with the main board control, and the electromagnet is connected with the main machine of the electronic device 100. When the host is folded, the closing electric signal is received and transmitted to the electromagnet, and the electromagnet generates magnetism and adsorbs the N-level iron block of the magnet.

When the whole electronic device 100 is unfolded normally, the whole electronic device transmits an electric signal to the battery iron, the electromagnet is controlled by the main board to lose adsorption force, magnetic force disappears, the spring is placed on the supporting plate 30 and is always in a state that the supporting plate 30 is pushed to be parallel to the bottom of the screen, the supporting plate 30 is restored by the spring force and returns to 9 to be in a flat position with the bottom of the screen, and therefore when fingers touch the screen, the fingers touch local depressions.
