[0025] Please refer to Figures 1 to 6 , an electronic drawing board with a projection function provided for an embodiment of the present utility model, which is used for projecting the electronic drawing board. The electronic drawing board with a projection function of the present utility model includes a drawing board body 10, a projection mounting base 20, a first projection column 30, a second projection column 40, and a projection component 50; a drawing board display screen 11 and drawing board keys 12 are provided on the drawing board body 10, and the projection mounting base 20 is provided on the drawing board body 10 on one side of the drawing board display screen 11; an installation hole 21 is provided on the projection mounting base 20, the first projection column 30 is inserted into the installation hole 21, the free end of the first projection column 30 is hinged to the second projection column 40, and the projection component 50 is installed at the free end of the second projection column 40.
[0026] The user can operate and input through the drawing board display screen 11 and drawing board keys 12 on the drawing board body 10; when projection is required, the projection component 50 starts to work; the projection mounting base 20 provides an installation basis for the first projection column 30; the first projection column 30 is inserted into the installation hole 21, ensuring the stability of its position; the first projection column 30 is hinged to the second projection column 40, enabling the second projection column 40 to adjust the angle relative to the first projection column 30; the projection component 50 installed at the free end of the second projection column 40 can then flexibly change the projection direction and angle according to actual needs.
[0027] This electronic drawing board with a projection function integrates the drawing board and the projection function in one device, facilitating the user to quickly switch between creation and display without the need to use multiple separate devices; it is also possible to create on the drawing board display screen 11 according to the image projected by the projection component 50, and quickly improve children's painting skills by imitating the composition, line application, color matching, etc. in the projected image; by hinging the second projection column 40 to the first projection column 30, the projection component 50 can flexibly adjust the angle and direction; when the projection function is not needed, the projection component 50 can be folded and retracted to reduce the occupied space.
[0028] Please refer toFigure 3 and Figure 4 The projection assembly 50 includes a disc-shaped projection housing 51, and a light source is disposed inside the projection housing 51; a light source channel 52 extends outward from the bottom of the projection housing 51, and an adjusting gear ring 53 extending to one side is disposed between the light source and the light source channel 52; a plurality of pattern lenses 530 are disposed on the adjusting gear ring 53, and the adjusting gear ring 53 is toggled to adjust the output pattern. When the projection assembly 50 operates, the light source inside the projection housing 51 emits light; the light first reaches the position of the adjusting gear ring 53; a plurality of pattern lenses 530 are disposed on the adjusting gear ring 53; by toggling the adjusting gear ring 53, different pattern lenses 530 will be located between the light source and the light source channel 52; when a specific pattern lens 530 is in this position, it will perform specific optical processes such as refraction, focusing, or filtering on the light emitted by the light source; the light processed by the pattern lens 530 is then projected outward through the light source channel 52, thereby forming a specific pattern outside; the setting of the plurality of pattern lenses 530 enables the user to easily switch out a variety of different patterns, meeting different creative needs and scenario requirements; without replacing complex components or performing cumbersome settings, different patterns can be quickly obtained, saving time and effort and improving the efficiency of work or creation; toggling the adjusting gear ring 53 can change the output pattern, and the operation is simple and intuitive, and can quickly respond to the needs of the user.
[0029] An outer edge of the light source channel 52 extends outward to form a focusing step 54 for adjusting the focus of the light source. By changing the position of the focusing step 54 relative to other parts of the projection assembly 50, the focusing degree of the light during propagation is adjusted; when the focusing step 54 moves outward, the divergence degree of the light will decrease, thereby achieving a clear projection at a farther distance, that is, achieving focus at a farther position; on the contrary, when the focusing step 54 moves inward, the divergence degree of the light will increase, making the projection clearly imaged at a closer distance, that is, achieving focus at a closer position. It can accurately adjust the focus of the light source according to different projection distances and requirements, ensuring that a clear projection image can be obtained in various situations; avoiding problems such as image blurring and distortion caused by inaccurate focusing, and improving the overall projection quality and visual effect.
[0030] A spherical rotation switch 55 extends upward from the top of the projection housing 51, and the rotation switch 55 is slid up and down to turn on or off the projection function of the projection assembly 50. The slidable rotation switch 55 is simple and intuitive, and the user can quickly turn on or off the projection function without complex operation steps, improving the usage efficiency; the spherical rotation switch 55 is compact in design and does not occupy too much surface space, making the appearance of the projection housing 51 more concise and beautiful.
[0031] Please refer to Figure 1 and Figure 6, the first projection post 30 includes a column body section 31 and an insertion section 32 inserted into the mounting hole 21, and the insertion section 32 is matched with the contour of the mounting hole 21; the insertion section 32 is inserted into the mounting hole 21, and the column body section 31 abuts against the projection mounting seat 20 outside the mounting hole 21. The insertion section 32 of the first projection post 30 is matched with the contour of the mounting hole 21. When the insertion section 32 is inserted into the mounting hole 21, this tight fit can ensure the accurate and stable position of the first projection post 30 in the mounting hole 21; after the insertion section 32 is inserted into the mounting hole 21, the column body section 31 abuts against the projection mounting seat 20 outside the mounting hole 21; to provide support and limitation to prevent the insertion section 32 from being inserted into the mounting hole 21 excessively, and at the same time, when the first projection post 30 is subjected to external force or rotates and moves during use, the forces are dispersed and borne through the abutment with the projection mounting seat 20, so as to ensure the stability and reliability of the first projection post 30.
[0032] The projection mounting seat 20 has a plurality of mounting holes 21, and the plurality of mounting holes 21 are arranged side by side on the projection mounting seat 20. The plurality of mounting holes 21 arranged side by side provide multiple optional mounting positions for the first projection post 30; when it is necessary to adjust the angle, height or position of the projection, the first projection post 30 can be inserted into different mounting holes 21; different positions of the mounting holes 21 correspond to different projection parameters; by selecting different mounting holes 21 to mount the first projection post 30, the overall position and angle of the projection assembly 50 can be changed quickly and flexibly to adapt to different usage requirements and environmental conditions.
[0033] Please refer to Figures 1 to 3 , the projection assembly 50 is spherically hinged with the second projection post 40. The spherical hinge enables the projection assembly 50 to rotate freely in multiple directions; when it is necessary to adjust the angle of the projection assembly 50, the projection assembly 50 can rotate omnidirectionally around the center of the sphere in three-dimensional space; it can be adjusted at multiple angles in three-dimensional space to meet various complex and special projection requirements; in the case of irregular space, obstacles or multiple viewing positions, the projection assembly 50 can be rotated flexibly to avoid obstacles and adapt to different viewing angles.
