[0064] Embodiment 1

[0065] Please refer to Figures 1 to 5 , Embodiment 1 of the present invention is: a display screen, comprising a display module and a protection mechanism arranged on the display module, wherein the protection mechanism comprises a protection block.

[0066] The protection block includes a fixed seat 1, a flip block 2, a first rotating shaft 3, a sliding arm 4 and a rotating arm 5. The first rotating shaft 3 is arranged on the fixed seat 1, one end of the flip block 2 is rotatably sleeved on the first rotating shaft 3, the rotating arm 5 is rotatably arranged on the fixed seat 1, the rotating arm 5 is movably connected with the sliding arm 4, one end of the sliding arm 4 is connected with one end of the flip block 2 through a rotating transmission structure, and the rotation of the rotating arm 5 drives the sliding arm 4 to rotate so as to flip the flip block 2. The protection mechanism of this embodiment has a compact structure, reliable functions and simple operation; each corner of the display screen has a flip block 2 respectively.

[0067] The rotation center axis of the first rotating shaft 3 is not arranged parallel to the rotation center axis of the rotating arm 5. In this embodiment, the rotation center axis of the first rotating shaft 3 is arranged perpendicular to the rotation center axis of the rotating arm 5.

[0068] Specifically, a plug-in block 51 is provided on the rotating arm 5 , a sliding groove 41 is provided on the sliding arm 4 , and the plug-in block 51 is slidably arranged along the sliding groove 41 . Optionally, the length direction of the sliding groove 41 is arranged perpendicular to the central axis of the first rotating shaft 3 .

[0069] Optionally, the rotation transmission structure is a gear transmission structure. In this embodiment, one end of the sliding arm 4 is a toothed surface end 42, and the sliding arm 4 is sleeved on the first rotating shaft 3 through the toothed surface end 42. The flip block 2 is provided with a plurality of limit posts 21 that match the toothed surface end 42, and the plurality of limit posts 21 are surrounded in a ring shape. Further, the first rotating shaft 3 is fixedly connected to the fixed seat 1, and the sliding arm 4 is rotatably arranged relative to the first rotating shaft 3; or, the first rotating shaft 3 is rotatably arranged on the fixed seat 1, and the sliding arm 4 is fixedly connected to the first rotating shaft 3.

[0070] In order to prevent the protective mechanism from getting stuck or the flip block 2 from flipping into place during operation, the protective block also includes a top-butting mechanism, which includes a top-butting block 61 and an elastic member 62. The top-butting block 61 is liftably arranged on the fixed seat 1, and the end of the sliding arm 4 away from the first rotating shaft 3 abuts against the top surface of the top-butting block 61 and can be slidably arranged along the top surface of the top-butting block 61. The elastic member 62 connects the top-butting block 61 and the fixed seat 1 and provides lift for the top-butting block 61. The top surface of the top-butting block 61 is an arc surface, a plane or an inclined surface. The setting of the top-butting mechanism can prevent the flip block 2 from stopping in the middle position during the flipping process and failing to play a protective role. The top-butting block 61 can give the sliding arm 4 an upward force. When the sliding arm 4 is tilted and does not reach its maximum swing position, the flip block 2 is in the middle position. At this time, the upward force will squeeze and force the sliding arm 4 to slide on the top surface of the top-butting block 61 until the sliding arm 4 reaches its maximum swingable stroke. When the sliding arm 4 reaches the maximum stroke position, the flip block 2 will be fully opened or fully closed, thereby avoiding the problem that the flip block 2 cannot flip into place and cannot play a protective role, and reducing the problem of the flip block 2 being damaged by external forces due to failure to flip into place.

[0071] Optionally, a guide column 63 is provided on the abutting block 61 , a guide hole (not shown) matching with the guide column 63 is provided on the fixing seat 1 , and the elastic member 62 is sleeved on the guide column 63 .

The traction rod 8 is movably connected to the rotating arm 5 through the cooperation of the connecting column and the connecting hole, and the connecting column can be rotatably arranged in the connecting hole.

[0074] It also includes a knob assembly, the other end of the traction rod 8 is connected to the knob assembly, and the rotation of the knob assembly drives the traction rod 8 to slide to drive the flip block 2 to flip.

[0075] Each knob assembly is connected to at least one traction rod 8. In other words, a plurality of flip blocks 2 can be driven by one button assembly. For example, the flipping of two flip blocks 2 can be driven by the action of one knob assembly.

[0076] Optionally, the knob assembly includes a connected knob 91 and a driving gear 92, and the driving gear 92 is connected to the traction rod 8. In order to prevent the overturning speed of the overturning block 2 from being too fast and causing an accident, the knob assembly also includes a driven gear 93 meshing with the driving gear 92, the diameter of the driven gear 93 is larger than the diameter of the driving gear 92, and the traction rod 8 is provided with a rack meshing with the driven gear 93, and the driving gear 92 is connected to the traction rod 8 through the driven gear 93.
