Because almost all blackboards are basically fixed, for teachers of different heights, taller teachers can reach the top of the blackboard and are more used to writing on the top of the blackboard, while the utilization rate of the bottom of the blackboard is not high. On the contrary, for small teachers, they are more used to writing at the bottom of the blackboard, and it will be more difficult to start writing from the top of the blackboard

Embodiment 1
[0037] An intelligent teaching device, comprising a lifting blackboard 1 and an infrared distance measuring sensor 2;
[0038] The lifting blackboard 1 is slidingly connected with the wall;
[0039] An infrared ranging sensor 2 is used to measure the distance from the user; the infrared ranging sensor 2 is arranged downward; the infrared ranging sensor 2 is arranged on the upper part of the lifting blackboard 1 side;
[0040] The lifting blackboard 1 includes a blackboard main body 101 and a moving mechanism, wherein the moving mechanism is used to drive the blackboard main body 101 to move up and down on the ground;
[0041] The infrared ranging sensor 2 is electrically connected with the controller, and the controller is electrically connected with the moving mechanism;
[0042] The controller is used to control the movement of the moving mechanism according to the value monitored by the infrared distance measuring sensor 2 . Wherein, the controller includes a power supply...
Embodiment 2
[0056] An intelligent teaching board, the moving mechanism includes a slide rail 102, a gear 103, a rack 104, and a roller 105; wherein, the slide rail 102 is set up and down on the wall;
[0057] The rack 104 is arranged in parallel with the slide rail 102, the rack 104 is fixedly connected to the wall, the gear 103 is fixedly connected to the blackboard main body 101, and the gear 103 meshes with the rack 104;
[0058] Rollers 105 are provided on the back of the blackboard main body 101 corresponding to the slide rail 102 .
[0059] In this embodiment, the slide rail 102 is fixed on the wall, and the rollers 105 on the back of the blackboard main body 101 can move along the slide rail 102 . Through the meshing of the gear 103 and the rack 104 , driven by the gear 103 , the blackboard main body 101 can move up and down. In this embodiment, the rotation of the gear 103, that is, the moving mechanism drives the blackboard main body 101 to move up and down, is controlled by a s...

Abstract
The invention discloses an intelligent teaching device and a teaching board, wherein the intelligent teaching device comprises a lifting blackboard and an infrared distance measuring sensor; the lifting blackboard is connected with a wall body in a sliding manner; the infrared distance measuring sensor is used for measuring the distance to a user; the infrared distance measuring sensor is arrangeddownwards; the infrared distance measuring sensor is arranged at the upper part of the side edge of the lifting blackboard; the lifting blackboard comprises a blackboard main body and a moving mechanism; the infrared distance measuring sensor is electrically connected with a controller, and the controller is electrically connected with the moving mechanism; and the controller is used for controlling the movement of the moving mechanism according to the numerical value monitored by the infrared distance measuring sensor. The invention also discloses an intelligent teaching board, and the moving mechanism comprises a slide rail, a gear, a rack and a roller; wherein, the slide rail is arranged on the wall body up and down; the rack is arranged in parallel with the sliding rail, the rack is fixedly connected with the wall body, the gear is fixedly connected with the blackboard main body, and the gear is meshed with the rack; and the back of the blackboard body corresponding to the slide rail is provided with the roller. The invention has the advantages of self-adjusting blackboard height and high moving reliability.
Description
technical field [0001] The invention relates to an intelligent teaching device and a teaching board. Background technique [0002] The blackboard is a tool for classroom teaching. Although the use of multimedia teaching is now being promoted, generally speaking, classroom teaching in various schools is still mainly based on blackboard writing. Because almost all blackboards are basically fixed, for teachers of different heights, taller teachers can reach the top of the blackboard and are more used to writing on the top of the blackboard, while the utilization rate of the bottom of the blackboard is not high. On the contrary, for small teachers, they are more used to writing at the bottom of the blackboard, and it will be more difficult to start writing from the top of the blackboard. Design a blackboard that can intelligently adjust the height. According to the height of the teacher, it can satisfy the teacher to always write at the most labor-saving height when writing on ...
