Abstract

The invention discloses a novel push-pull type blackboard. The novel push-pull type blackboard comprises a first blackboard and a second black which can move left and right, wherein the first blackboard is arranged behind the second blackboard; an outer border is arranged on the peripheries of the first blackboard and the second blackboard; a liquid crystal display screen is arranged in the middleof the top of the outer border; a plurality of LED lamps are arranged on each of the left side and the right side of the outer border; a switch and a key group are arranged at the lower left corner of the outer border; a first magnet is arranged in the middle of the rear of the first blackboard, and a speed sensor, an acceleration sensor and a controller are arranged at the lower part of the rearof the first blackboard; a coil is arranged on the periphery of the first magnet; and a second magnet is arranged in the middle of the rear of the second blackboard. According to the novel push-pulltype blackboard, the speed of the blackboard and the electrodynamic potential of the coil are changed by moving the blackboard, and the change is displayed by the liquid crystal display screen; and bymeans of control over lighting and extinguishing of the LED lamps, the classroom atmosphere is activated, and the teaching effect is improved.

Description

technical field [0001] The invention relates to a blackboard, in particular to a novel push-pull type blackboard. Background technique [0002] The existing push-pull blackboard expands the area of ​​the blackboard and improves the teaching effect; however, the frame of the existing push-pull blackboard is not additionally utilized, and the movement process of the push-pull blackboard is not additionally utilized. If the blackboard can also carry the function of experiment and interaction while carrying the function of writing teaching information, the teaching effect can be further promoted. Contents of the invention [0003] In order to solve the above technical problems, the present invention proposes a novel push-pull blackboard, which carries the functions of experiment and interaction, and promotes the teaching effect. [0004] In order to achieve the above object, the technical solution of the present invention is as follows: a novel push-pull blackboard, including...
