Please refer to FIG. 3 , at this time, the electronic device (ie, the mobile phone) is in a folded state, and the cover 20 is stacked on the top of the housing 10 . When the user wants to use the mobile phone, he can push the cover 20 so that the sliding member 60 is driven by the cover 20 to slide toward the rear end of the housing 10 (as shown in FIGS. 4 and 6 ).

When the cover body 20 slides back for an appropriate distance, the rotating assembly 40 is driven by the first elastic member 50 to synchronously drive the sliding member 60 to rotate relative to the fixing assembly 30, so that the cover body 20 can rotate upward relative to the housing 10 . Simultaneously, the sliding member 60 continues to slide relative to the rotating assembly 40. After the cover body 20 continues to slide upward to the position, the mobile phone is in a sliding state (as shown in FIGS. 5 and 7 ). Shown), so that the screen 22 is raised at an angle relative to the casing 10, so that the user can watch the content of the screen 22 conveniently.

In addition, the action relationship between the above-mentioned fixing component 30, rotating component 40, supporting member 70, and elastic buckling member 80 is further detailed as follows:

When the cover 20 is slid up, as shown in FIGS. The end 72 slides forward to the second position. At this time, the buckling part 821 of the elastic buckling part 80 is buckled on the moving part 721 on the side of the second end 72 of the supporting part 70, so that the first The two end portions 72 are located at the second position. In other words, when the cover 20 is in the state of sliding up, the utility model uses the elastic buckle 80 to support the supporting member 70, so as to provide an appropriate supporting force on the rear side of the cover 20, so that the cover Body 20 will not fall down easily.

Furthermore, since the first end 71 of the support 70 is connected to the rotating assembly 40, the cover plate 322 of the fixed assembly 30 blocks the moving part 721 of the second end 72 of the support 70, so the The supporting member 70 between the fixing component 30 and the rotating component 40 functions to limit the rotation angle of the cover 20 .

On the contrary, when wanting to cover the cover body 20 downward, as shown in FIG. 11 and FIG. The force of the buckling part 821 pushing outward makes the moving part 721 of the supporting part 70 break away from the buckling of the buckling part 821, and makes the second end part 72 slide back to the first position, so The cover body 20 can then be smoothly returned to the closed state (as shown in FIG. 3 ).
