[0023] Embodiment

[0024] Please refer to Figures 1-3 The utility model discloses a multi-angle visual multimedia teaching board, including teaching display component 200 and the support of teaching display component 200 for adjusting the support 100,

[0025] The support 100 includes a base 101, a rotary table 102 matched with the built-in rotary drive of the base 101, a positioning frame 104 fixed to the upper middle position of the rotary table 102, a triangular support 105 fixed to the inside of the positioning frame 104, a drive motor 106 installed on the top of the triangular support 105, a worm 108 connected to the output end of the drive motor 106, a worm gear 109 matched with the worm 108, and an arm 107 fixed to the side away from the worm 108 of the worm gear 109.

[0026] The teaching display component 200 includes a support plate 202 fixed to the end of the arm 107, a display screen 201 fixed to the outside of the support plate 202, and display modules 203 symmetrically fixed to the inside of the support plate 202.

[0027] Specifically, the support 100 further includes a controller 103 fixed to the upper side of the rotary table 102, the controller 103 is wirelessly connected to the remote control end, and the controller 103 is also connected to the built-in rotary drive of the base 101 and the drive motor 106, the display modules 203 are connected to the display screen 201 through internal wires, and the display modules 203 are internally integrated with a power supply unit.

[0028] Further, the worm 108 is rotationally arranged in the middle of the triangular support 105, and the worm gear 109 matched therewith is rotationally arranged on the edge of the triangular support 105 through a shaft, and the upper and lower swing angle range of the arm 107 is 30°.

[0029] The multi-angle visual multimedia teaching board provided by the technical solution aims to provide a flexible and multifunctional teaching tool, so that teachers or speakers can display content at different angles, and the position and angle of the display screen 201 can also be adjusted through remote control, and the specific description of the structure setting is as follows:

[0030] The base 101 in the support 100 serves as the foundation of the entire device, which not only provides stable support, but also has a rotary drive system (which can be a motor-driven gear mechanism or a stepper motor, etc., capable of accurately controlling the rotation angle of the turntable 102, which is a relatively mature and conventional technology, and no restrictive description is made herein) built-in. The rotary drive enables the turntable 102 to rotate 360 degrees without dead angles. The controller 103 is used to receive wireless signals from a remote control end (such as a remote control or a smart device) and convert these signals into operation instructions for the rotary drive and the drive motor 106. The positioning frame 104 is used for the installation and fixation of the triangular support 105, and the triangular support 105 has enough space inside to accommodate the transmission mechanism of the worm 108 and the worm gear 109. The drive motor 106 is responsible for driving the rotation of the worm 108, and the transmission system composed of the worm 108 and the worm gear 109 is used to drive the up-and-down swinging of the arm 107, ultimately realizing the vertical angle adjustment of the teaching display assembly 200.

[0031] The support plate 202 in the teaching display assembly 200 is directly fixed at the end of the arm 107, providing an installation interface for the display screen 201. The display screen 201 is the main output terminal of the multimedia content, and the display module 203 integrates power supply units, image processing chips, audio decoding, and other functional modules. It is connected to the display screen 201 through internal wires to ensure the reliability of power supply and data transmission.

[0032] Working principle

[0033] When the user wants to change the angle of the display screen 201, first send a signal to the controller 103 through the remote control end. After receiving the instruction, the controller 103 will control the rotary drive system in the base 101 to rotate the turntable 102 according to the preset program, or start the drive motor 106 to rotate the worm 108, and then drive the arm 107 to swing up and down through the worm gear 109, so as to realize the precise control of the position of the display screen 201 in the horizontal and vertical planes. At the same time, the display module 203 is responsible for processing and outputting image signals to the display screen 201 to complete the playback of multimedia content.
