Detailed implementation manners

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical staff in the art without creative work fall within the protection scope of the present invention.

[0017] Please refer to Figures 1 to 14 Figures 1 to 14 , the present invention provides a technical solution: a data display platform for a smart education platform, including a mobile box body 1, a plurality of locking mechanisms 3 are connected to both sides of the top of the mobile box body 1, a rotating motor 5 is connected to one side of the mobile box body 1, storage cavities are provided on both side walls of the mobile box body 1, box cover mechanisms 2 are connected to both sides of the top of the mobile box body 1, and an adjusting mechanism 4 is connected inside the mobile box body 1. The adjusting mechanism 4 includes sector gears 41 rotatably connected to both sides inside the storage cavity. The two sector gears 41 are meshed with each other. One end of the top of the sector gear 41 is connected to a telescopic arm rod assembly 42, and the top of the telescopic arm rod assembly 42 is connected to the box cover mechanism 2. It should be noted that: the number of sector gears 41 is four. Since the two sector gears 41 are meshed with each other, when one sector gear 41 rotates, the other sector gear 41 can rotate in the opposite direction. Since the bottom end of the telescopic arm rod assembly 42 is connected to the shaft of the sector gear 41, the telescopic arm rod assembly 42 can rotate with the sector gear 41, so as to drive the box cover mechanism 2 to move. A plurality of top corners at the bottom of the mobile box body 1 are connected with universal wheels, which is convenient for the user to move the mobile box body 1.

[0018] A sector gear 41 is connected to the driving end of a rotating motor 5. One side of the sector gear 41 is connected to a first connecting rod 43. Two corresponding first connecting rods 43 on both sides are connected by a synchronizing shaft 44. One side of the bottom of the first connecting rod 43 is rotatably connected to a second connecting rod 45. The top of the second connecting rod 45 is rotatably connected to a support plate 46. A long-stroke telescopic assembly 47 and a short-stroke telescopic assembly 48 are respectively connected to both sides of the support plate 46. The top of the short-stroke telescopic assembly 48 is rotatably connected to a protection frame 49. The top of the long-stroke telescopic assembly 47 is slidably connected to the protection frame 49. A display screen 410 is embedded in the top of the protection frame 49. It should be noted that: the rotating motor 5 drives the two sector gears 41 and the synchronizing shaft 44 to rotate, thereby driving the adjacent sector gear 41 and the synchronizing shaft 44 to rotate, so that the telescopic arm rod assembly 42 can be rotated, and then the lid mechanism 2 can be moved. At the same time, the sector gear 41 drives the first connecting rod 43 to rotate, thereby driving the second connecting rod 45 to lift, and then the support plate 46, the short-stroke telescopic assembly 48, the long-stroke telescopic assembly 47, the protection frame 49 and the display screen 410 are lifted. When the long-stroke telescopic assembly 47 and the short-stroke telescopic assembly 48 cooperate with the lifting rack 6, when the long-stroke telescopic assembly 47 and the short-stroke telescopic assembly 48 rise, the long-stroke telescopic assembly 47 and the short-stroke telescopic assembly 48 can be extended. When the rising heights of the long-stroke telescopic assembly 47 and the short-stroke telescopic assembly 48 are the same, the extension height of the long-stroke telescopic assembly 47 is greater than the extension height of the short-stroke telescopic assembly 48, that is, the height of the long-stroke telescopic assembly 47 is greater than the height of the short-stroke telescopic assembly 48, realizing the flipping of the display screen 410, thereby realizing the adjustment of the angle of the display screen 410, and the angle of the display screen 410 can be adjusted by adjusting the rising height of the display screen 410.

[0019] Both sides of the lid mechanism 2 are slidably connected to the lifting rack 6, and the lifting rack 6 cooperates with the long-stroke telescopic assembly 47 and the short-stroke telescopic assembly 48. It should be noted that: descending grooves are provided at multiple top corners of the top of the moving box body 1, so that there is a descending space when the lifting rack 6 descends, which is convenient for hiding the lifting rack 6.

[0020] In this embodiment, as Figure 1 、 Figure 2 、 Figure 7 、 Figure 8 、 Figure 11 、 Figure 12 and Figure 13As shown in the figure, the lid mechanism 2 includes a first cover plate 21 slidably connected to the top of the moving box body 1, a first buffer assembly 23 connected to both sides of the first cover plate 21, and a second cover plate 22 rotatably connected to one side of the top of the first cover plate 21. Limiting chutes are provided on both sides of the second cover plate 22, and the chute bodies of the limiting chutes are slidably connected to the lifting rack 6. It should be noted that: T-shaped chutes are provided on both sides of the top of the moving box body 1, and T-shaped sliders are fixed to both sides of the bottom of the first cover plate 21. The T-shaped sliders are slidably connected to the chute bodies of the T-shaped chutes to limit the position of the first cover plate 21 and prevent the first cover plate 21 from lifting and lowering. One end face of the first cover plate 21 is in contact with one end face of the second cover plate 22 close to the first cover plate 21 to limit the rotation angle of the second cover plate 22, so that the second cover plate 22 cannot rotate downward when in the initial state. Therefore, during the process of the second cover plate 22 moving outward, the second cover plate 22 can only flip upward. When the second cover plate 22 flips, the upper surfaces of the second cover plate 22 and the first cover plate 21 are in contact, which can limit the rotation angle of the second cover plate 22 and improve the stability of the second cover plate 22. Baffles are fixed to both sides of the top and bottom of the lifting rack 6 to limit the moving distance of the lifting rack 6. During the flipping process of the second cover plate 22, the lifting rack 6 moves by gravity, so that the baffle at the bottom contacts the second cover plate 22.

[0021] The first buffer assembly 23 includes a first telescopic member 231 connected to both sides of the first cover plate 21, a first spring 232 sleeved on the first telescopic member 231, and a moving block 233 connected to one side of the first telescopic member 231. One side of the moving block 233 is connected to the telescopic arm rod assembly 42. It should be noted that: the elastic force of the first spring 232 can reset the moving block 233, and the first spring 232 stops the first cover plate 21 from moving, and there is a buffer space when the telescopic arm rod assembly 42 rotates, so as to prevent the telescopic arm rod assembly 42 from being difficult to rotate when the first cover plate 21 stops moving.

[0022] Extension shafts are provided on both sides of the second cover plate 22. One end of the extension shaft passes through a fixed block provided on the top of the first cover plate 21 to connect the first arm rod 24, and one side of the first arm rod 24 is rotatably connected to the guide post 25.

[0023] On both sides of the top of the moving box body 1, two guide plates 11 are fixed. On the side of the guide plate 11 close to the guide post 25, a guide groove 12 is provided, and the groove body of the guide groove 12 is matched with the guide post 25. It should be noted that: the guide groove 12 is composed of a V-shaped groove with a downward opening and two horizontal grooves of different lengths. The two horizontal grooves are located on both sides of the V-shaped groove. During the process of the second cover plate 22 moving outward, the guide post 25 slides in the guide groove 12. When the guide post 25 slides to the V-shaped groove, the guide post 25 is first pushed up by the first arm rod 24, and then pulled down by the first arm rod 24. During this process, the first arm rod 24, the extension shaft and the second cover plate 22 rotate 180°, so as to realize the flipping of the second cover plate 22. After the second cover plate 22 finishes flipping, the second cover plate 22 moves synchronously with the first cover plate 21, and the guide post 25 is always located in the guide groove 12 to prevent the second cover plate 22 from rotating due to other factors.

[0024] In this embodiment, as Figure 12 and Figure 14 shown, on both sides of the bottom of the first cover plate 21, limit grooves 211 are provided. On one side of the bottom of the groove body of the limit groove 211, a storage groove 212 is provided. The groove body of the limit groove 211 is connected to the second buffer assembly 28. The second buffer assembly 28 includes a second telescopic member 281 connected to the groove body of the limit groove 211, a second spring 282 sleeved on the second telescopic member 281, and an L-shaped plate 283 connected to one side of the second telescopic member 281. The L-shaped plate 283 is slidably connected to the groove body of the storage groove 212. It should be noted that: the elastic force of the second spring 282 can reset the L-shaped plate 283 and provide a buffer space for the L-shaped plate 283.

[0025] On both sides of the inner end of the first cover plate 21, hidden grooves are provided. The groove body of the hidden groove is connected to the limit assembly 29. The limit assembly 29 includes a third spring 291 connected to the groove body of the hidden groove and a limit post 292 connected to one side of the third spring 291. The limit post 292 is matched with the positioning groove 61 provided on one side of the lifting rack 6. It should be noted that: the elastic force of the third spring 291 can make the limit post 292 enter the positioning groove 61, so as to limit the position of the lifting rack 6. One end of the limit post 292 is rotatably connected with a roller to reduce the friction between the limit post 292 and the lifting rack 6. When the second cover plate 22 flips, the lifting rack 6 moves in an arc. The limit post 292 will squeeze the lifting rack 6 to prevent the lifting rack 6 from moving before the limit post 292 is engaged with the positioning groove 61. One side of the bottom of the limit post 292 is provided with an arc edge, so that when the lifting rack 6 flips with the second cover plate 22, the limit post 292 will not cause interference. However, the limit post 292 will limit the lifting of the lifting rack 6.

[0026] In this embodiment, as Figure 5 and Figure 6As shown, the locking mechanism 3 is located on one side of the guide plate 11, and the locking mechanism 3 includes a fixed plate 31 connected to the top of the mobile box 1, two fixed columns 311 connected to the bottom of the fixed plate 31, a cam 32 rotatably connected to one side of the fixed plate 31, and a convex plate 35 connected to one side of the bottom of the cam 32, and the convex plate 35 is located between the two fixed columns 311. It should be noted that the convex plate 35 will rotate with the cam 32, and the contact between the convex plate 35 and the fixed column 311 will limit the rotation of the cam 32.

[0027] One side of the top of the cam 32 is rotatably connected to the lifting plate 33 , one side of the bottom of the lifting plate 33 is slidably connected to the translation plate 34 , and one side of the translation plate 34 is slidably connected to the moving box 1 .

[0028] One end of the cam 32 away from the convex plate 35 is rotatably connected to the rotating shaft 38, one side of the rotating shaft 38 is sleeved with a fourth spring 37, one side of the fourth spring 37 is connected to the rotating block 36, one side of the rotating block 36 is rotatably connected to the fixed plate 31, the hole body set in the rotating block 36 is slidably connected to the rotating shaft 38, one end of the rotating shaft 38 away from the fourth spring 37 is rotatably connected to the second arm 39, one side of the bottom of the second arm 39 is rotatably connected to the lifting rod 310, the lifting rod 310 is slidably connected to the moving box 1, and the lifting rod 310 cooperates with the groove body of the limiting groove 211. It should be noted that: the lifting plate 33 and the translation plate 34 are moved by pushing the lifting plate 33, so that the cam 32 can be rotated. When the cam 32 rotates, the lifting plate 33 can be lifted and lowered, and at the same time, the convex plate 35 will rotate with the cam 32. The contact between the convex plate 35 and the fixed column 311 can limit the rotation of the cam 32. During the rotation of the cam 32, the rotating shaft 38 and the rotating block 36 will rotate accordingly, thereby driving the second arm 39 to rotate, and then the lifting rod 310 can be lifted and lowered. When the lifting rod 310 rises, it will enter the limiting groove 211 to limit the movement of the first cover plate 21. When the lifting rod 310 descends, it will disengage from the limiting groove 211 to cancel the restriction of the first cover plate 21.

[0029] In this embodiment, Figure 6 , Figure 8 and Figure 11As shown in the figure, on both sides of the first cover plate 21, extrusion columns 26 are connected. The extrusion columns 26 are located on one side of the first buffer assembly 23. On the side of the extrusion column 26 close to the lifting plate 33, a T-shaped rod 27 is connected. And the extrusion column 26 cooperates with the lifting plate 33. A rectangular hole 331 is provided at the top of the lifting plate 33. Rectangular grooves 332 are provided on both sides of the rectangular hole 331. The groove body of the rectangular groove 332 and the hole body of the rectangular hole 331 cooperate with the T-shaped rod 27. It should be noted that: The T-shaped rod 27 is composed of a rectangular rod and a rectangular plate. The width of the rectangular plate is greater than the width of the rectangular rod. Since the distance between the two rectangular grooves 332 is equal to the width of the rectangular plate, and the height of the rectangular groove 332 is equal to the height of the rectangular plate, the rectangular rod and the rectangular plate can pass through the rectangular groove 332. That is, during the process of the first cover plate 21 moving outward, the T-shaped rod 27 will first pass through the rectangular groove 332, and then the extrusion column 26 will squeeze the lifting plate 33, thereby pushing the lifting plate 33 and the translation plate 34 to move, so that the cam 32 can rotate (the rotation direction is that the smaller end of the cam 32 rotates downward). At this time, when the cam 32 rotates, it can make the lifting plate 33 rise, causing the rectangular plate to be misaligned with the rectangular groove 332. At this time, the rectangular rod cooperates with the rectangular hole 331; when the first cover plate 21 moves back, due to the misalignment of the rectangular plate and the rectangular groove 332, the rectangular plate will squeeze the lifting plate 33, thereby pulling the lifting plate 33 to move, and further making the cam 32 rotate (the rotation direction is that the smaller end of the cam 32 rotates upward). When the cam 32 rotates, it can make the lifting plate 33 descend, making the rectangular plate correspond to the rectangular groove 332 (that is, the lifting plate 33 returns to the initial state). When the T-shaped rod 27 continues to move, the rectangular plate passes through the rectangular groove 332 to make the T-shaped rod 27 separate from the lifting plate 33, and the extrusion column 26 will not collide with the guide plate 11 during the moving process.

[0030] In this embodiment, as Figure 9 and Figure 10 shown, the telescopic arm rod assembly 42 includes a support rod 421 connected to one side of the sector gear 41, a fixed cylinder 422 connected to the top of the support rod 421, a fifth spring 423 connected to the inside of the fixed cylinder 422, and a telescopic rod 424 connected to the top of the fifth spring 423. The telescopic rod 424 is slidably connected to the inner wall of the fixed cylinder 422, and the top of the telescopic rod 424 is rotatably connected to the moving block 233. It should be noted that: The elastic force of the fifth spring 423 can make the telescopic rod 424 reset, which is more conducive to the reset of the moving block 233 and the first cover plate 21. When the support rod 421, the fixed cylinder 422, and the telescopic rod 424 rotate with the sector gear 41, the telescopic rod 424 contracts and the fifth spring 423 is compressed, thereby making the moving block 233 and the first cover plate 21 move.

[0031] In this embodiment, as Figure 9 and Figure 10As shown in the figure, the long-stroke telescopic assembly 47 includes a first square cylinder 471 connected to one side of the support plate 46 and a first gear 472 rotatably connected to one side of the top of the first square cylinder 471. A first rack 473 is connected to the side of the inner wall of the first square cylinder 471 away from the first gear 472. A first lifting cylinder 474 is slidably connected to the inner wall of the first square cylinder 471. A second rack 475 is connected to the side of the first lifting cylinder 474 close to the first gear 472. The second rack 475 is meshed with the first gear 472, and the first gear 472 is matched with the lifting rack 6. It should be noted that: the lifting rack 6 flips with the second cover plate 22. When the first cover plate 21 stops moving, the lifting rack 6 is located above the first gear 472. At this time, the first gear 472 can rise to be meshed with the lifting rack 6, so that the first gear 472 rotates, and then the second rack 475 and the first lifting cylinder 474 can rise.

[0032] A second gear 476 is rotatably connected to the side of the first lifting cylinder 474 close to the first rack 473. The second gear 476 is meshed with the first rack 473.

[0033] A second lifting cylinder 478 is slidably connected to the inner wall of the first lifting cylinder 474. A third rack 477 is connected to the side of the second lifting cylinder 478 close to the second gear 476. The third rack 477 is meshed with the second gear 476. It should be noted that: the second gear 476 rises with the first lifting cylinder 474. Since the second gear 476 is meshed with the first rack 473, the second gear 476 rotates when it rises. By the rotation of the second gear 476, the third rack 477 and the second lifting cylinder 478 can rise.

[0034] A first cross plate 479 is connected to the top of the second lifting cylinder 478. A first rotating seat is fixed to the top of the first cross plate 479. A moving rod 4710 is rotatably connected to the top of the first rotating seat. The top of the moving rod 4710 is slidably connected to the protection frame 49. It should be noted that: the lengths of the first rotating seat and the moving rod 4710 are long enough so that the protection frame 49 will not cause interference when rotating. T-shaped grooves are provided on both sides of the bottom of the protection frame 49. A T-shaped block is fixed to the top of the moving rod 4710. The T-shaped block is slidably connected to the groove body of the T-shaped groove.

[0035] In this embodiment, as Figure 9 and Figure 10 shown, the short-stroke telescopic assembly 48 includes a second square cylinder 481 connected to one side of the support plate 46 and a third gear 482 rotatably connected to one side of the top of the second square cylinder 481. A third lifting cylinder 484 is slidably connected to the inner wall of the second square cylinder 481. A fourth rack 483 is connected to the side of the third lifting cylinder 484 close to the third gear 482. The fourth rack 483 is meshed with the third gear 482, and the third gear 482 is matched with the lifting rack 6.

[0036] The top of the third lifting cylinder 484 is connected to the second cross plate 485. A second rotating seat is fixed to the top of the second cross plate 485, and the top of the second rotating seat is rotatably connected to the protection frame 49. It should be noted that when the first cover plate 21 stops moving, the lifting rack 6 is located above the third gear 482. At this time, when the third gear 482 rises, it can mesh with the lifting rack 6, so that the third gear 482 rotates, and then the fourth rack 483 and the third lifting cylinder 484 can rise. The length of the second rotating seat is long enough so that the protection frame 49 will not cause interference during rotation. The second cross plate 485 and the first cross plate 479 rise to different heights, making the protection frame 49 tilt.

[0037] The usage method of the data display platform for a smart education platform is as follows: The working process is as follows: S1. When the display screen 410 needs to be used, the rotation motor 5 drives the two sector gears 41 and the synchronous shaft 44 to rotate, thereby driving the adjacent sector gears 41 and the synchronous shaft 44 to rotate. Through the synchronous shaft 44, the sector gears 41 in the two storage cavities can rotate synchronously. Thus, when the support rod 421, the fixed cylinder 422, and the telescopic rod 424 rotate with the sector gear 41, the telescopic rod 424 contracts at the same time, so that the moving block 233 and the first cover plate 21 move simultaneously. The second cover plate 22 and the guide post 25 move with the first cover plate 21. When the guide post 25 moves into the guide groove 12 and the guide post 25 slides to the V-shaped groove, the lifting of the guide post 25 can drive the first arm rod 24 to rotate, so that the extension shaft and the second cover plate 22 rotate, realizing the flipping of the second cover plate 22. During the flipping process, the lifting rack 6 moves by gravity, so that the bottom baffle contacts the second cover plate 22. At this time, the elastic force of the third spring 291 can make the limit post 292 enter the positioning groove 61 to realize the positioning of the lifting rack 6; S2. During the movement of the first cover plate 21, the extrusion column 26 and the T-shaped rod 27 will move synchronously with the first cover plate 21. During the movement, first, the T-shaped rod 27 will pass through the rectangular groove 332 and the rectangular hole 331, and then the lifting plate 33 and the translation plate 34 are pushed by the extrusion column 26 to move, so that the cam 32 can rotate. When the cam 32 rotates, the lifting plate 33 can rise, making the T-shaped rod 27 misaligned with the rectangular groove 332. At the same time, the convex plate 35 will rotate with the cam 32. When the convex plate 35 contacts the fixed column 311, it can limit the rotation of the cam 32. During the rotation of the cam 32, the rotating shaft 38 and the rotating block 36 will rotate accordingly, thereby driving the second arm rod 39 to rotate, and then the lifting rod 310 rises. The rising of the lifting rod 310 will enter the limit groove 211 to limit the movement of the first cover plate 21; S3. While the first cover plate 21 moves, the sector gear 41 drives the first connecting rod 43 to rotate, thereby driving the second connecting rod 45 to rise, and further realizing the rise of the support plate 46, the short-stroke telescopic assembly 48, the long-stroke telescopic assembly 47, the protection frame 49 and the display screen 410. When the lifting rod 310 enters the limit groove 211, the upper surface of the protection frame 49 is in the same plane as the upper surface of the first cover plate 21. At the same time, the lifting racks 6 on both sides are respectively located above the first gear 472 and the third gear 482. Subsequently, the protection frame 49 continues to rise. At this time, the telescopic rod 424 rotates to drive the moving block 233 to move, compressing the first spring 232. During the rising process of the protection frame 49, the first square cylinder 471 and the second square cylinder 481 can be raised. Since the lifting racks 6 are engaged with the first gear 472 and the third gear 482, the first gear 472 and the third gear 482 can be rotated. The first gear 472 drives the second rack 475 and the first lifting cylinder 474 to rise, thereby driving the second gear 476 to rotate, and further driving the third rack 477, the second lifting cylinder 478 and the first cross plate 479 to rise. At the same time, the third gear 482 drives the fourth rack 483, the third lifting cylinder 484 and the second cross plate 485 to rise. Since the rising heights of the second cross plate 485 and the first cross plate 479 are different, the protection frame 49 can rise and rotate, so that the protection frame 49 and the display screen 410 are inclined; S4. When the display screen 410 needs to be stored, the motor 5 is rotated to drive the sector gear 41 and the telescopic rod 424 to rotate, so that the display screen 410 can be lowered and the first cover plate 21 can be moved. During the lowering process of the display screen 410, first, the display screen 410 is parallel to the first cover plate 21, then the display screen 410 is lowered, then the second cover plate 22 flips back to its original position, and finally the first cover plate 21 is closed to achieve storage.
