[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figures 1 to 6 As shown, an embodiment of the utility model proposes an adjustable smart blackboard, which includes a cross 4, on which two mounting frames 3 are hingedly connected; a blackboard body 1, which is divided into two groups and is respectively arranged on the two mounting frames 3, wherein each blackboard body 1 is embedded with a touch screen body 2, and the two touch screen bodies 2 are abutted against each other; an adjustment component, including a control member and a driving member for driving the control member to move, the control member is divided into two groups, both of which are arranged on the cross 4, located at the rear side of the two mounting frames 3, and corresponding to the mounting frames 3 one by one, the driving member is arranged on the cross 4, and is used to drive the two control members to move synchronously, and the control member is used to control the corresponding mounting frame 3 to rotate around its hinge point; a lifting mechanism, which is arranged at the rear side of the cross 4, is used to adjust the height of the cross 4.

[0023] The detailed working process of this embodiment is as follows: the touch screen body 2 is embedded in the blackboard body 1 so that the touch screen body 2 and the blackboard body 1 are integrated, and the panel of the touch screen body 2 is a writable material (this material is the existing technology, and is processed by nano-microcrystalline technology, so that the particle size of the surface glass can be increased, the friction can be increased, and the adhesion of chalk writing can be stronger, so chalk words can be written directly on the display screen). When the touch screen body 2 is black, it can be regarded as an ordinary writing blackboard, and touch operations can also be performed on the touch screen body 2 to present teaching content in the form of pictures, videos, etc., and the writing board can be used for teachers to write on the blackboard. Presenting teaching content in the form of blackboard writing can realize the combination of traditional teaching and electronic teaching and improve teaching effectiveness. Figure 1It can be seen that the two blackboard bodies 1 abut against each other, and the touch screen bodies 2 inside the two blackboard bodies 1 also abut against each other. When adjusting the angle, it is adjusted around the abutment so that the abutting boards will not separate and form a gap, thereby improving the user experience.

[0024] The mounting frame 3 is used to mount the blackboard body 1. By changing the simple combination of the traditional integrated electronic tablet and the writing board into two hinged blackboards and the electronic tablet embedded in the two blackboards, the two blackboards are connected by hinges so that the two blackboards can rotate around their hinge points to adjust the angle at which students view the blackboard, thereby avoiding the problem that students cannot see the content on the blackboard due to reflection of the blackboard. When in use, the driving member drives the two control members to move synchronously, and the synchronously moving control members can drive the two blackboards to move simultaneously to adjust the angle at which students view the blackboard. The lifting mechanism is used to adjust the overall height of the blackboard to meet the needs of teachers and students of different heights.

[0025] like Figure 3 and Figure 4 As shown, the driving member includes a bidirectional screw 602 and a second driving source 603. Two stroke grooves 407 are opened on the cross 4. The bidirectional screw 602 is rotatably set in the cross 4 and passes through the two stroke grooves 407. The second driving source 603 is set on the cross 4. Transmission teeth 605 are set on one end of the bidirectional screw 602 and the output shaft of the second driving source 603, and the two transmission teeth 605 are meshed with each other.

[0026] like Figure 3 and Figure 4 As shown, each control component includes a control arm 6 and a U-shaped seat 601. The control arm 6 is hinged on the cross 4. The U-shaped seat 601 is slidably set in the corresponding travel groove 407 and is threadedly connected with the bidirectional screw 602. One end of the control arm 6 is located in the U-shaped seat 601. A slide groove 301 is set on the rear side of each mounting frame 3. A movable seat 604 is slidably set in each slide groove 301. The end of the corresponding control arm 6 away from the U-shaped seat 601 is rotatably connected to the corresponding movable seat 604.

[0027] The detailed working process of this embodiment is as follows: the function of the bidirectional screw 602 is to simultaneously drive the U-shaped seat 601 to move closer to or away from each other in the stroke groove 407, the function of the second driving source 603 is to drive the bidirectional screw 602 to rotate in the whole box or in the opposite direction, the function of the control arm 6 is to control the rotation angle of the corresponding mounting frame 3, and the U-shaped seat 601 is used to adjust the control arm 6. When adjusting the blackboard angle, first control the second driving source 603 to rotate so that it drives the bidirectional screw 602 to rotate, and the bidirectional screw 602 rotates to drive the U-shaped seat 601 in the stroke groove 407 to move. When the U-shaped seat 601 moves, it will drive the control arm 6 to rotate. Its hinge point rotates, and at this time the control arm 6 pushes out the mounting bracket 3 through the lever principle. A movable seat 604 is rotatably set at one end of the control arm 6, and one end of the movable seat 604 is located in the slide slot 301 and can move left and right. Through the setting of the movable seat 604, the mounting bracket 3 rotated to a certain angle can be pulled back to the initial position. When the two U-shaped seats 601 move away from each other, the two mounting brackets 3 rotate around the hinge. When the two U-shaped seats 601 approach each other, the mounting bracket 3 returns to the initial position. The two-way screw 602 is threadedly connected to the U-shaped seat 601, so that the U-shaped seat 601 has self-locking properties, which can ensure that the stability of the mounting bracket 3 can be ensured when the mounting bracket 3 is rotated to any angle.

[0028] The second driving source 603 in the embodiment is an electric motor. In other embodiments, a suitable driving device can be selected according to actual needs.

[0029] like Figure 2 and Figure 3 As shown, the lifting mechanism includes two threaded columns 401 and a first driving source 405. Two mounting seats 404 are fixedly provided at both ends of the rear side of the cross 4. The two threaded columns 401 are threadedly connected to the two mounting seats 404 respectively. A transmission wheel 402 is provided at one end of the two threaded columns 401. The two transmission wheels 402 are transmission connected through a toothed pulley 406. The first driving source 405 is transmission connected to any one of the threaded columns 401.

[0030] like Figure 3 As shown, a fixing seat 403 is disposed at each end of the two threaded columns 401 .

[0031] The detailed working process of this embodiment is as follows: the function of the first driving source 405 is to drive the two threaded columns 401 to rotate, and the function of the fixing seat 403 is to fix the corresponding threaded column 401 on the wall. By setting the two threaded columns 401 and the mounting seat 404, the height of the cross 4 is changed, thereby changing the height of the blackboard when in use. The function of the toothed pulley 406 is to drive the two threaded columns 401 to rotate at the same time and prevent slipping during operation, thereby ensuring that the transmission ratio of the two threaded columns 401 is the same, and ensuring the horizontal consistency of the rise and fall of the blackboard on the two threaded columns 401. When adjusting the height of the blackboard, control the first driving source 405 to drive the two threaded columns 401 to rotate. The rotation of the two threaded columns 401 can drive the blackboard to move up and down, thereby adjusting the height of the blackboard.

[0032] like Figure 4 As shown, a roller 5 is disposed on the rear side of the cross 4 , the roller 5 is located between two mounting seats 404 , and the roller 5 is coplanar with each fixing seat 403 .

[0033] The detailed working process of this embodiment is as follows: the roller 5 increases the fulcrum of the blackboard, improves its stability, and avoids shaking during writing. After installation, the roller 5 will contact the wall behind the blackboard to prevent the blackboard from hanging in the air, thereby improving its stability.

[0034] like Figure 2 As shown, protective covers are provided at the meshing position of the two transmission teeth 605 and the toothed belt pulley 406 .

[0035] The detailed working process of this embodiment is as follows: the function of the protective cover is to protect the meshing gears while improving the appearance and preventing them from leaking out.

[0036] The implementation principle of the embodiment of the present application is: when adjusting the angle of the blackboard, first control the second driving source 603 to rotate so that it drives the bidirectional screw 602 to rotate. The bidirectional screw 602 rotates to drive the U-shaped seat 601 in the travel groove 407 to move. When the U-shaped seat 601 moves, it will drive the control arm 6 to rotate around its hinge point. At this time, the control arm 6 pushes out the mounting frame 3 through the lever principle. One end of the control arm 6 is rotatably provided with a movable seat 604, and one end of the movable seat 604 is located in the slide groove 301 and can move left and right. Through the setting of the movable seat 604, the mounting frame 3 rotated to a certain angle can be pulled back to the initial position. When the two U-shaped seats 601 move away from each other, the two mounting frames 3 rotate around the hinge. When the two U-shaped seats 601 are close to each other, the mounting frame 3 returns to the initial position.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
