Description
DESCRIPTION LU502390
TECHNICAL FIELD The invention relates to the field of painting tools, in particular to a copyable drawing board for children.
BACKGROUND Drawing board is a tool for children's entertainment and learning. Children can draw and write on it, so children's drawing board is deeply loved by children and parents. For example, CN203974382U discloses a colorful and high-brightness three-dimensional drawing board, which comprises a lighting device, a light-transmitting board and a frame for fixing the light-transmitting board, wherein the lighting device comprises an LED lamp, and at least one side of the light-transmitting board is provided with an LED lamp groove with the same size as the LED. When in use, children can draw on the light-transmitting board, or lay drawing paper under the light-transmitting board to facilitate children's copying. However, children need to prepare drawing paper when copying, and different drawing papers need to be replaced when drawing different pictures. It is troublesome to replace the pictures, and the needed pictures cannot be found quickly, which brings great inconvenience to children and parents in using drawing boards.
SUMMARY The invention aims to provide a copyable drawing board for children to solve the technical problem that the drawing board is inconvenient to change pictures.
The technical scheme of the invention is as follows: A copyable drawing board for children comprises a light-transmitting board and a frame fixed on the edge of the light-transmitting board, the frame is connected with a display device located at the rear side of the light-transmitting board, and the display device comprises a display device shell, the display device shell is internally provided with a controller and a memory module for storing images, the display device shell is provided with a display screen for displaying images, the display screen and the storage module are both connected with a controller, the display device shell is also provided with a switch button and an image switchit&/502390 button connected with the controller, and the light-transmitting board and the display screen are arranged back and forth correspondingly, so that the image displayed on the display screen can be seen from the front side of the light-transmitting board.
Optionally, the frame is provided with a clamping structure, and the display device is clamped on the rear side of the transparent board through the clamping structure.
Optionally, the frame is fixed with a magnet, and the display device shell is provided with a magnetic attraction part magnetically attracted the magnet to fix the display device on the frame.
Optionally, the magnet protrudes backward from the frame to form a bulge, and the magnetic attraction part is a groove matched with the bulge.
Optionally, the display device shell is provided with a USB interface for connecting a computer for data transmission.
Effect of Invention A display device is connected to the frame, and the display screen of the display device is arranged at the front and back of the light-transmitting board correspondingly. By switching the image button, the controller can control the display device to change the image, and the image on the display screen can be seen from the front side of the light-transmitting board. When in use, children can copy the image displayed on the display screen at the rear side of the light-transmitting board on the light-transmitting board, and the image can be changed conveniently and quickly.
Further, the display device is clamped on the rear side of the light-transmitting plate through the clamping structure, and the display device can be taken down or installed at any time. Children can install the display device when drawing, and take it down to enjoy the painting after drawing, which is convenient to use.
BRIEF DESCRIPTION OF THE FIGURES Fig. 1 is a front view of a copyable drawing board for children; Fig. 2 is the rear view of the copyable drawing board for children.
In the figures: 1: frame front shell; 2: frame rear shell; 3: light-transmitting board; 4: display device; 5: clamping structure; 6: button.
In an embodiment, as shown in figs. 1-2, a copyable drawing board for children includesl&/502390 light-transmitting board 3 and a frame fixed on the edge of the light-transmitting board 3, and the frame includes a frame front shell 1 and a frame rear shell 2.
An inner cavity is formed between the front shell and the rear shell of the frame. The inner cavity is provided with a central controller, a storage battery and RGB light sources. The frame is provided with a power switch. The central controller includes a single chip microcomputer, a voice control module and an RGB output module. The voice control module, the power switch, the storage battery and the RGB output module are respectively connected with the single chip microcomputer, and the RGB output module is connected with the RGB light sources. When the drawing board works, it detects the surrounding sound through the voice control module, and transmits the dimming signal to the single chip microcomputer when the sound reaches the set value. In the single chip microcomputer, a variety of dimming modes are implanted, which can be dimmed once every time a signal is received, and the dimming can be controlled by cheers and applause.
The frame is provided with a clamping structure 5 which can be a clip. The frame is connected with a display device 4 located at the rear side of the light-transmitting board 3 through a clamping structure. The display device comprises a display device shell, a controller and a storage module for storing images arranged in the display device shell, wherein a display screen for displaying images is arranged on the display device shell, and the storage device is connected with the controller. The rear side of the display device shell is also provided with a button 6 connected with the controller and a USB interface for connecting the computer for data transmission. The buttons include a switch button and a switch image button. The display screen is arranged in front of and behind the light-transmitting board so that the image displayed on the display screen can be seen from the front side of the light-transmitting board. When in use, the controller controls the display screen to switch images by switching the image button, and the images can be changed at any time, so that different images can be copied on the light-transmitting board, and the operation is convenient.
In an embodiment, magnets with magnetism are fixed on the frame, and the display device shell is provided with a magnetic attraction part which attracts the magnets to fix the display device on the frame. The fixing between the display device and the frame is simple and quick,
and can be removed at any time. The magnet can be a protrusion protruding backward from thé/502390 frame, and the magnetic attraction part is a groove, and the magnet and the magnetic attraction part are matched and inserted, so that the fixing reliability between the display device and the magnet can be further ensured, and the relative position between the display device and the magnet can also be ensured.
In an embodiment, the display device can also be fixed on the frame through a screw connection structure.
In an embodiment, the display device can also be fixed on the frame by welding or bonding.
