[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This dual-screen foldable graphics tablet, after the protective shell 1 and protective shell 2 are straightened, allows the user to rotate a rotating block, which in turn drives a cylinder to rotate. The rotating cylinder, in turn, drives a gear to rotate. The moving rod engages with the gear through a toothed block 1, causing the gear to apply pressure to the toothed block 1. This pressure causes the moving rod to move along the inner wall of the fixed block, which in turn moves the toothed clamping block. When the toothed clamping block reaches the outer wall of the toothed block 2, it engages with the toothed block 2, limiting the movement of the toothed block 2 and the rotating rod, thus fixing the folded protective shell 1 and protective shell 2.

This dual-screen foldable digital tablet, when display screen one and display screen two are folded, the protective shell one and protective shell two collide during folding, causing the protective plate to move towards the inner wall of the placement slot under pressure. The protective plate, when moving, applies pressure to the pressure plate, causing the pressure plate to drive the placement rod to rotate on the inner wall of the placement block. The rotation of the pressure plate applies pressure to the moving block, causing the moving block to move on the outer wall of the fixed rod. The movement of the moving block applies pressure to springs one and two, causing the elastic potential energy of springs one and two to be released. Springs one and two drive the protective plate to buffer, thereby protecting display screen one and the connecting plate when folded. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1 - Figure 6 A dual-screen foldable graphics tablet includes a protective shell 1, a display screen 2 fixedly mounted on the inner wall of the protective shell 1, a fixing block 3 fixedly mounted on the outer wall of the protective shell 1, a cylinder 13 rotatably connected to the inner wall of the fixing block 3, a rotating block 4 and a gear 14 fixedly mounted on the outer wall of the cylinder 13, a rotating rod 5 rotatably connected to the outer wall of the fixing block 3, a moving rod 15 slidably connected to the inner wall of the fixing block 3, a toothed block 16 fixedly mounted on the outer wall of the moving rod 15, a toothed clamping block 17 fixedly mounted on the outer wall of the moving rod 15, a toothed block 2 18 fixedly mounted on the top of the outer wall of the rotating rod 5, a placement groove 12 opened on the outer wall of the protective shell 1, and a protective component 11 provided on the inner wall of the placement groove 12.
[0024] In the above structure, after the protective shell 1 and the protective shell 9 are adjusted to a straight state, the user rotates the rotating block 4, which drives the cylinder 13 to rotate during the rotation. The cylinder 13 further drives the gear 14 to rotate during the rotation. At the same time, the moving rod 15 meshes with the gear 14, so that the gear 14 applies pressure to the toothed block 16 when it rotates. After the toothed block 16 is subjected to pressure, it causes the moving rod 15 to move on the inner wall of the fixed block 3, thereby pushing the toothed clamping block 17 to move. When the toothed clamping block 17 moves to the outer wall of the toothed block 18, it meshes with the toothed block 18, causing the toothed block 18 and the rotating rod 5 to be limited, thereby fixing the folded protective shell 1 and the protective shell 9.
[0025] In a preferred embodiment: a rotating plate 6 is fixedly mounted on the outer wall of the rotating rod 5, a rotating column 7 is rotatably connected to the inner wall of the rotating plate 6, a connecting plate 8 is fixedly mounted on the outer wall of the rotating column 7, a protective shell 9 is fixedly mounted on the outer wall of the connecting plate 8, and a display screen 10 is fixedly mounted on the inner wall of the protective shell 9.
[0026] In the above structure, the rotating rod 5 and the rotating column 7 enable the rotating plate 6 and the connecting plate 8 to rotate better, making it easier to fold the display screen 12 and the display screen 20. The protective shell 1 and the protective shell 2 9 protect the four sides of the display screen 12 and the display screen 20, preventing damage to the display screen 12 and the display screen 20 during use.
[0027] In a preferred embodiment: the protective component 11 includes a fixed rod 1101, a movable block 1102 is slidably connected to the outer wall of the fixed rod 1101, a spring 1103, a spring 1104 and a placement block 1105 are fixedly mounted on the outer wall of the movable block 1102 respectively, a placement rod 1106 is rotatably connected to the inner wall of the placement block 1105, one end of a pressure plate 1107 is fixedly mounted on the outer wall of the placement rod 1106, and a protective plate 1108 is fixedly mounted on the other end of the pressure plate 1107.
[0028] In the above structure, during the folding and placement of display screen 12 and display screen 20, protective shell 1 and protective shell 29 collide with each other during folding, causing the protective plate 1108 to bear pressure and move towards the inner wall of the placement groove 12. Subsequently, during the movement, the protective plate 1108 applies pressure to the pressure plate 1107, causing the pressure plate 1107 to push the placement rod 1106 to rotate on the inner wall of the placement block 1105 after being pressed. During the rotation, the pressure plate 1107 applies pressure to the moving block 1102, causing the moving block 1102 to move on the outer wall of the fixed rod 1101. During the movement, the moving block 1102 applies pressure to the spring 1103 and spring 2 1104, causing them to release elastic potential energy after being pressed. Finally, the spring 1103 and spring 2 1104 drive the protective plate 1108 to buffer through the released elastic potential energy, thereby achieving a protective function when folding display screen 12 and connecting plate 8.
[0029] In a preferred embodiment: the fixed rod 1101, spring 1103 and spring 2 1104 are all fixedly assembled to the inner wall of the placement groove 12, and the moving rod 15 is driven by meshing with the gear 14 through the toothed block 16.
[0030] In the above structure, the placement groove 12 is used to limit the position of the protective component 11 so that the protective component 11 will not fall off when placed. When the gear 14 rotates, it will drive the moving rod 15 and the toothed block 16 to move on the inner wall of the fixed block 3.
[0031] In a preferred embodiment: the rotating rod 5 engages with the toothed clamping block 17 via the toothed block 2 18, and the protective plate 1108 is adapted to the inner wall of the placement groove 12.
[0032] In the above structure, when the toothed clamping block 17 clamps the toothed block 18 on the outer wall of the rotating rod 5, it will limit the rotation rod 5 so that the rotating rod 5 will not rotate when placed. By adapting the protective plate 1108 to the inner wall of the placement groove 12, the protective plate 1108 will not get stuck in the groove of the placement groove 12 when it moves.
[0033] In a preferred embodiment: there are two sets of protective components 11, and the two sets of protective components 11 are located on the outer walls of protective shell 1 and protective shell 9 respectively. There are two rotating blocks 4, cylinders 13, gears 14, moving rods 15, toothed blocks 16, toothed clamping blocks 17 and toothed blocks 18, and the two rotating blocks 4, cylinders 13, gears 14, moving rods 15, toothed blocks 16, toothed clamping blocks 17 and toothed blocks 18 are located on the inner walls of fixed blocks 3 and rotating plates 6 respectively.
[0034] In the above structure, the rotating rod 5 and the rotating column 7 are fixed by two rotating blocks 4, cylinder 13, gear 14, moving rod 15, toothed block 16, toothed clamping block 17 and toothed block 18, so as to prevent the rotating rod 5 and the rotating column 7 from rotating when the equipment is used. The two sets of protective components 11 protect the display screen 12 and the display screen 210, so as to prevent the display screen 12 and the display screen 210 from colliding when folded.
[0035] Working principle: After adjusting protective shell 1 and protective shell 9 to an upright position, the user rotates the rotating block 4, causing the cylinder 13 to rotate accordingly. The rotation of the cylinder 13 in turn drives the gear 14 to rotate. Simultaneously, the moving rod 15 is driven by the meshing of the toothed block 16 and the gear 14. When the gear 14 rotates, it applies pressure to the toothed block 16. After being pressed, the toothed block 16 pushes the moving rod 15 along the inner wall of the fixed block 3. The movement of the moving rod 15 causes the toothed clamping block 17 to move accordingly. When the toothed clamping block 17 moves to the outer wall of the toothed block 18, it meshes with the toothed block 18, thereby restricting the movement of the toothed block 18 and the rotating rod 5, ensuring that the folded protective shell 1 and protective shell 9 are fixed. When screen 12 and display screen 210 are placed side by side, protective shell 1 and protective shell 29 collide with each other during the folding process, causing the protective plate 1108 to be under pressure and move along the inner wall of the placement groove 12. The movement of the protective plate 1108 applies pressure to the pressure plate 1107. After being pressed, the pressure plate 1107 drives the placement rod 1106 to rotate on the inner wall of the placement block 1105. The rotation of the pressure plate 1107 applies pressure to the moving block 1102, causing the moving block 1102 to move on the outer wall of the fixed rod 1101. The movement of the moving block 1102 applies pressure to the spring 1103 and spring 2104, so that while they release elastic potential energy, the buffering effect of the spring 1103 and spring 2104 protects the display screen 12 and the connecting plate 8 from damage during the folding process.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
