The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0036] Please also read Figure 1-Figure 5 This embodiment provides a teaching display board, including a placement frame 1, a bottom plate assembly 2, a top plate 3, a lifting assembly 4, a moving assembly 5, a wiper assembly 6 and a driving mechanism 7.

[0037] The placement frame 1 is provided with a slide groove 11 from bottom to top, and the bottom plate assembly 2 and the top plate 3 are respectively arranged one high and one low and are slidably arranged in the slide groove 11. Specifically, there are four slide grooves 11, which are arranged on the left and right sides of the placement frame 1 in pairs, one pair of which is slidably provided with the bottom plate assembly 2, and the other pair of which is slidably provided with the top plate 3.

[0038] In other schemes, the bottom plate assembly 2 includes a bottom plate body 21 and a rack 22; the bottom plate body 21 is slidably disposed in the slide groove 11 and connected to the lifting assembly 4, and the rack 22 is disposed on the bottom plate body 21; the bottom plate body 21 is slid toward the top of the placement frame 1, and the rack 22 can store energy for the driving mechanism 7, and drive the moving assembly 5 to rotate after the bottom plate body 21 reaches the top. It should be understood that the top plate 3 and the bottom plate body 21 can stop at any height of the slide groove 11 through the friction force with the slide groove 11, and the top plate 3 and the bottom plate body 21 move in opposite directions, and remain up and down in the initial state.

[0039] In other solutions, a damper is further provided inside the slide groove 11. The damper is provided to further increase the friction between the top plate 3 and the bottom plate body 21 and the slide groove 11, thereby preventing the bottom plate body 21 or the top plate 3 from falling spontaneously.

[0040] The lifting assembly 4 is arranged in the placement frame 1 and is connected to the bottom plate assembly 2 and the top plate 3 respectively, so that the sliding of the bottom plate assembly 2 drives the top plate 3 to slide in the opposite direction.

[0041] In other embodiments, the lifting assembly 4 includes a lifting fixed pulley 41 and a connecting rope 42; the lifting fixed pulley 41 is rotatably disposed on the placement frame 1, one end of the connecting rope 42 is connected to the bottom plate body 21, and the other end is connected to the top plate 3 through the lifting fixed pulley 41. It should be understood that the lifting assembly 4 is disposed on both sides of the bottom plate body 21 and the top plate 3, and the connecting rope 42 is wound around the lifting fixed pulley 41.

[0042] The moving assembly 5 is rotatably arranged on the placing frame 1 , and the wiping plate assembly 6 is arranged on the moving assembly 5 and can abut against the bottom plate assembly 2 . The moving assembly 5 is rotated, and the wiping plate assembly 6 can reciprocate in the placing frame 1 .

[0043] In other schemes, the moving assembly 5 includes a driving wheel 51, a driven wheel 52 and a conveyor belt 53; the driving wheel 51 and the driven wheel 52 are rotatably arranged in the placement frame 1, respectively, and are close to two opposite sides; the conveyor belt 53 tightly embraces the driving wheel 51 and the driven wheel 52, and the wiper assembly 6 is arranged on the conveyor belt 73; the driving mechanism 7 is connected to the driving wheel 51 and can drive the driving wheel 51 to rotate. It should be understood that the rotation of the driving wheel 51 drives the rotation of the conveyor belt 53, and then can drive the wiper assembly 6 arranged on the conveyor belt 53 to make a reciprocating motion. It should be understood that the placement frame 1 is provided with a mounting plate for the driving wheel 51 and the driven wheel 52.

[0044] In other schemes, the wiper assembly 6 includes a wiper body 61 and a wiper connecting rod 62; one end of the wiper connecting rod 62 is connected to the conveyor belt 53, and the other end is connected to the wiper body 61, and the wiper body 61 can abut the bottom plate body 21. It should be understood that the wiper body 61 can squeeze and abut the bottom plate body 21, and after the bottom plate body 21 slides from the bottom to the top, the wiper body 61 can be moved from one side to the other side; conversely, after the bottom plate body 21 slides from the top to the bottom, the wiper body 61 returns to the initial position from the other side. It should also be known that the wiper body 61 is hinged to the wiper connecting rod 62, and the wiper body 61 is always arranged vertically.

[0045] The driving mechanism 7 is rotatably disposed in the placement frame 1. Sliding the bottom plate assembly 2 toward the top of the placement frame 1 can enable the driving mechanism 7 to store energy, and release the energy after the bottom plate assembly 2 reaches the top, thereby driving the moving assembly 5 to rotate.

[0046] In other schemes, the driving mechanism 7 includes a driving assembly 71, a one-way assembly 72 and a conveyor belt 73; the driving assembly 71 and the one-way assembly 72 are rotatably arranged in the placement frame 1 respectively, and the conveyor belt 73 tightly embraces the one-way assembly 72 and the conveyor belt 53; the rack 22 slides to the top of the placement frame 1 to drive the driving assembly 71 to rotate forward, so that the driving assembly 71 accumulates energy; when the rack 22 slides to the top and leaves the driving assembly 71, the driving assembly 71 releases energy and reverses, thereby driving the one-way assembly 72 to rotate; when the rack 22 slides to the bottom, it can drive the driving assembly 71 to reverse. It should be understood that the forward rotation of the driving assembly 71 will not drive the one-way assembly 72 to rotate. When the rack 22 leaves the driving assembly 71, that is, when the bottom plate body 21 slides to the top, the driving assembly 71 releases the accumulated kinetic energy and starts to reverse, driving the one-way assembly 72 to rotate, and then the conveyor belt 73 drives the driving wheel 51 to rotate.

[0047] In other schemes, the driving assembly 71 includes a first connecting plate 711, a rotating shaft 712, a gear 713, a torsion spring 714, a turntable 715, a pawl 716 and a reset spring 717; the first connecting plate 711 is arranged in the placement frame 1, the rotating shaft 712 is rotatably connected to the first connecting plate 711, the gear 713 and the turntable 715 are coaxially arranged on the rotating shaft 712, and the gear 713 can engage with the rack 22; one end of the torsion spring 714 is connected to the turntable 715, and the other end is connected to the first connecting plate 711; the pawl 716 is slidably connected to the turntable 715 and slides along the axial direction of the turntable 715, the pawl 716 is connected to the rotating shaft 712 through the reset spring 717, and the reverse rotation of the pawl 716 unidirectionally drives the one-way assembly 72 to rotate. It should be understood that the sliding of the rack 22 drives the gear 713 to rotate, and then the forward rotation of the rotating shaft 712 drives the torsion spring 714 to undergo a resettable bending deformation, and the pawl 716 will not drive the one-way component 72 to rotate during the forward rotation; when the bottom plate body 21 slides to the highest point, the rack 22 leaves the gear 713, the torsion spring 714 resets and drives the pawl 716 to reverse, and the reverse rotation of the pawl 716 drives the one-way component 72 to rotate, so that the wiper body 61 moves from one side to the other.

[0048] In other embodiments, the one-way component 72 includes a second connecting plate 721 and an inner ratchet ring 722; the second connecting plate 721 is arranged in the placement frame 1 and connected to the inner ratchet ring 722. The inner side of the inner ratchet ring 722 is circumferentially provided with a plurality of ratchets corresponding to the pawl 716. The reverse rotation of the pawl 716 can drive the ratchet to rotate.

[0049] It should be understood that the driving mechanism 7 is disposed between the bottom plate body 21 and the top plate 3 .

[0050] When the bottom plate assembly of the above-mentioned teaching display board is lifted, the driving mechanism can store energy. After the bottom plate assembly reaches the top, the driving mechanism releases energy, driving the moving mechanism to rotate, so that the wiping plate assembly slides to the other side, that is, after the bottom plate assembly moves to the top, the wiping plate assembly spontaneously wipes the bottom plate assembly; when the bottom plate assembly is reset downward, the wiping plate assembly is reset accordingly.
