Wherein the plunger 30 is configured to pass through the insertion hole 101 and abut against the transmission member 20 when the fall self-locking mechanism 100 falls, so as to prevent the transmission member 20 from rotating relative to the fixing member 10. That is, when the fall self-locking mechanism 100 falls, the plunger 30 passes through the insertion hole 101 and abuts against the transmission member 20 to prevent the transmission member 20 from rotating relative to the fixing member 10.

Specifically, the fixing element 10 may include a fixing frame 11, and a first fixing plate 12 and a second fixing plate 13 connected to the fixing frame 11, wherein the first fixing plate 12 and the second fixing plate 13 may be connected to one inclined plate 200 in an abutting manner and fixedly connected to the inclined plate 200, so as to fixedly connect the fixing element 10 and the inclined plate 200.

The inserting end 31 is cylindrical, the inserting hole 101 is circular and has a diameter corresponding to that of the inserting end 31, on one hand, the inserting end 31 can reciprocate along the axial direction of the inserting hole 101, so that the inserting rod 30 can abut against the transmission plate 21, on the other hand, the edge angle of the inserting end 31 is reduced, and the inserting end 31 is prevented from being clamped with the fixing frame 11. The diameter of cap end 32 is greater than the diameter of plug end 31, so that the plug rod and reset piece 40 can be conveniently fixed, and plug rod 30 can be prevented from penetrating through jack 101.

When the falling self-locking mechanism 100 falls, the inserted link deforms the resetting element 40 under the action of gravity inertia, specifically, the cap end 32 compresses the resetting element 40 and makes the resetting element 40 in a compressed state, so that the inserted link 30 passes through the insertion hole 101 and abuts against the transmission plate 21 to prevent the transmission piece 20 from rotating relative to the fixing piece 10; after the falling self-locking mechanism 100 falls, the resetting member 40 returns to the initial state, and then the cap end 32 is driven to abut against the second baffle 52, the inserting end 31 is far away from the transmission member 20, and the inserting end 31 and the transmission member 20 are kept far away from each other.

When the falling self-locking mechanism 100 falls, the inserted link deforms the resetting element 40 under the action of gravity inertia, specifically, the cap end 32 stretches the resetting element 40 and makes the resetting element 40 in a stretched state, so that the inserted link 30 passes through the insertion hole 101 and abuts against the transmission plate 21 to prevent the transmission piece 20 from rotating relative to the fixing piece 10; after the falling self-locking mechanism 100 falls, the resetting member 40 returns to the initial state, and then drives the inserting end 31 to be away from the transmission member 20, so that the inserting end 31 and the transmission member 20 are kept away from each other. That is, the restoring member 40 is configured to deform when the fall self-locking mechanism 100 falls so that the plug rod 30 passes through the insertion hole 101 and abuts against the transmission member 20 to prevent the transmission member 20 from rotating relative to the fixed member 10, and is further configured to restore the initial state of the elastic sheet 43 after the fall self-locking mechanism 100 falls so that the plug rod 30 is away from the transmission member 20.

When the falling self-locking mechanism 100 falls, the elastic sheet 43 deforms to enable the insert rod 30 to pass through the insert hole 101 and abut against the transmission plate 21 so as to prevent the transmission piece 20 from rotating relative to the fixing piece 10; after the falling self-locking mechanism 100 falls, the elastic sheet 43 returns to the initial state, so that the insertion rod 30 is far away from the transmission member 20 and the insertion end 31 and the transmission member 20 are kept far away. That is, the elastic sheet 43 is configured to deform when the fall self-locking mechanism 100 falls so that the plug rod 30 passes through the insertion hole 101 and abuts against the transmission member 20 to prevent the transmission member 20 from rotating relative to the fixing member 10, and also configured to restore the initial state of the elastic sheet 43 after the fall self-locking mechanism 100 falls so that the plug rod 30 is away from the transmission member 20.

Optionally, an internal thread may be disposed in the mounting hole 431, and the insert rod 30 may be connected to the elastic piece 43 through a thread after sequentially passing through the mounting hole 431 and the through hole 501, so as to fixedly connect the insert rod 30 and the elastic piece 43; the elastic sheet 43 can also be directly connected with the cap end 32 by welding, so as to realize the fixed connection between the inserted link 30 and the elastic sheet 43.

Referring to fig. 8, in another embodiment, restoring member 40 may further include an eccentric 44 and an elastic member 45 fixedly connected to eccentric 44.

The elastic member 45 may be fixed to an end of the eccentric wheel 44 away from the eccentric hole 441, so that the elastic member 45 is fixedly connected to the insert rod 30. Alternatively, the resilient member 45 may be fixedly attached directly to the cap end 32. When the falling self-locking mechanism 100 falls, the elastic element 45 deforms to enable the insertion rod 30 to penetrate through the insertion hole 101 and abut against the transmission plate 21 to prevent the transmission piece 20 from rotating relative to the fixing piece 10, and after the falling self-locking mechanism 100 falls, the elastic element 45 restores to the initial state to enable the insertion rod 30 to be far away from the transmission piece 20 and enable the insertion end 31 to be far away from the transmission piece 20. That is, the elastic member 45 is configured to deform when the fall self-locking mechanism 100 falls so that the plunger 30 passes through the insertion hole 101 and abuts against the transmission member 20 to prevent the transmission member 20 from rotating relative to the fixed member 10, and is also configured to restore the initial state after the fall self-locking mechanism 100 falls so that the plunger 30 is away from the transmission member 20.

The electromagnetic valve 46 is fixedly connected with the inserted rod 30 and can drive the inserted rod 30 to abut against or be far away from the transmission piece 20, and the acceleration sensor 47 is used for judging whether the falling self-locking mechanism 100 is in a weightless state. When the acceleration sensor 47 determines that the falling self-locking mechanism 100 is in a weightless state, the electromagnetic valve 46 drives the insert rod 30 to abut against the transmission plate 21 so as to prevent the transmission member 20 from rotating relative to the fixing member 10; when the acceleration sensor 47 determines that the fall self-locking mechanism 100 is in a non-weightless state, the electromagnetic valve 46 drives the plug rod 30 to be away from the transmission member 20 and keeps the plug end 31 and the transmission member 20 in a away state. That is, the solenoid valve 46 is configured to drive the plunger 30 against the transmission member 20 to prevent the transmission member 20 from rotating relative to the fixing member 10 when the fall self-locking mechanism 100 is in a weightless state, and is further configured to drive the plunger 30 away from the transmission member 20 when the fall self-locking mechanism 100 is in a non-weightless state.

According to the falling self-locking mechanism 100 provided by the application, when the falling self-locking mechanism 100 falls, the insertion end 31 abuts against the transmission plate 21 to prevent the transmission piece 20 from rotating relative to the fixing piece 10; after the falling of the falling self-locking mechanism 100 is finished, the insert rod 30 is driven by the reset member 40 to be away from the transmission member 20 and keep the insert end 31 away from the transmission member 20.

Referring to fig. 10 to 13, the connecting member 300 may include a transition shell 301 and a first connecting member 302 and a second connecting member 303 respectively fixed to the transition shell 301. The falling self-locking mechanism 100 is respectively connected with the first connecting pieces 302 in a rotating way so as to realize the rotating connection of the two sloping plates 200.

Specifically, the first rotating member 302 is provided with two second rotating structures 3021 which are adjacently arranged. The two second rotating structures 3021 of the first connecting piece 302 correspond to and are rotatably connected to one first rotating structure 231 of the two fall self-locking mechanisms 100. In this embodiment, the first rotating structure 231 is a semi-circular protrusion, the corresponding second rotating structure 3021 may be a semi-circular groove, and the first rotating structure 231 is accommodated in and rotatably connected to the second accommodating structure, so that the falling self-locking mechanism 100 rotates relative to the connecting member 300. Alternatively, the first rotating structure 231 is a semicircular groove, the corresponding second rotating structure 3021 can be a semicircular bump, and the first rotating structure 231 receives and is rotatably connected with the second receiving structure, so that the falling self-locking mechanism 100 can rotate relative to the connecting member 300.

The first connecting piece 302 is provided with a first fixing hole 3022, the adaptor shell 301 is provided with a second fixing hole 3011 corresponding to the first fixing hole 3022, and the first connecting piece 302 passes through the corresponding first fixing hole 3022 and second fixing hole 3011 through a fixing member 10, such as a screw, to realize the fixed connection between the first connecting piece 302 and the adaptor shell 301.

Optionally, the number of the first connectors 302 is at least two and the first connectors are arranged oppositely at intervals. The second driving end 23 and the first connecting member 302 are alternately arranged to improve the reliability of the rotational connection between the first connecting member 302 and the second driving end 23.

The second connector 303 may include a base plate 3031 and a plurality of gears 3032 rotatably coupled to the base plate 3031, the plurality of gears 3032 being sequentially engaged. Specifically, the first connector 302 has a plurality of first tooth holes 3023 opened on a side of the substrate 3031 facing the second connector 303, and the substrate 3031 has a second tooth hole 3033 corresponding to the plurality of first tooth holes 3023 opened on a side facing the first connector 302. Each gear 3032 comprises a gear shaft 3034, and both ends of the gear shaft 3034 of each gear 3032 are respectively accommodated in the corresponding first tooth hole 3023 and the second tooth hole 3033, so that each gear 3032 can rotate relative to the first connecting piece 302 and the base plate 3031.

The gears 3032 are sequentially meshed, so that the fixing pieces 10 of the fall self-locking mechanisms 100 fixed on the two sloping plates 200 can be linked with the transmission piece 20 in a rotating way. That is, in any one of the fall self-locking mechanisms 100, the fixed member 10 cannot rotate relative to the transmission member 20, and the fixed members 10 of the other fall self-locking mechanisms 100 cannot rotate relative to the transmission member 20.

A third fixing hole 3035 is formed in the second connecting member 303, a fourth fixing hole 3012 corresponding to the third fixing hole 3035 is formed in the adapter shell 301, and the second connecting member 303 passes through the corresponding third fixing hole 3035 and the fourth fixing hole 3012 through a fixing member 10, such as a screw, so that the second connecting member 303 and the adapter shell 301 are fixedly connected.

According to the folding rotating shaft device 1000 provided by the application, the plurality of gears 3032 of the second connecting piece 303 are sequentially meshed, so that the rotating connection of the fixing pieces 10 of the plurality of falling self-locking mechanisms 100 and the transmission piece 20 can realize linkage; when any one of the falling self-locking mechanisms 100 is self-locked, that is, the inserted rod 30 of any one of the falling self-locking mechanisms 100 passes through the insertion hole 101 and abuts against the transmission member 20, the fixing members 10 of the other falling self-locking mechanisms 100 cannot rotate relative to the transmission member 20, so that the rotation of the folding rotating shaft device 1000 is in a locked state. Through the above manner, the foldable rotating shaft device 1000 can be folded without bending when falling, that is, without rotating between the two inclined plates 200, so as to reduce the impact on the flexible display screen 2000.
