Technical Field

[0002] Children's drawing board is a drawing tool designed specifically for children, aiming to promote children's creativity and artistic expression. There are many types of children's drawing boards. Among them, the magnetic children's drawing board uses its own magnetic principle to make the painting process simpler, less likely to get dirty, and easy to clean. At the same time, it is easy to carry and does not require carrying a paintbrush, which prevents children from coming into contact with paint. It is deeply loved by parents and children.
[0003] For example, announcement number: CN209492328U discloses "a magnetic drawing board", including a drawing board, an outer frame, a first magnetic component arranged on the drawing board, and a second magnetic component arranged on the outer frame. The first magnetic component and the second magnetic component correspond in position. The first magnetic component can attract the second magnetic component to adsorb and fix the outer frame on the drawing board, thereby fixing the drawing paper placed on the drawing board between the drawing board and the outer frame.
[0004] However, in the prior art, children's magnetic drawing boards are mainly used indoors or outdoors, and there are no magnetic drawing boards for use in family cars. In life, children will enter a graffiti period after reaching a certain age, and like to scribble everywhere. After graffiti indoors or outdoors, the external space is large and it is easy for parents to clean. However, when scribbling in the car, especially after children graffiti in small spaces such as cup holders, central control, and seat sides in the car, it is very inconvenient to clean due to the small space in the car. Although the existing magnetic drawing boards can be carried in the car for use, they lack a mechanism for fixing and adjusting in the car, and cannot be stably placed in the car and adjusted to a suitable angle for children to doodle. As a result, parents or children need to hold the drawing board with their hands to doodle stably, which is very inconvenient to use. Summary of the invention

The side of the drawing board mechanism 1 is fixedly connected to the No. 1 connecting outer plate 33, and the No. 3 slide rail 41 is internally slidably connected with two No. 3 sliders 42. The No. 2 adjusting screw rod 43 is rotatably connected to the No. 3 slide rail 41, and the surface of the No. 2 adjusting screw rod 43 is provided with two threads in opposite directions. The two No. 3 sliders 42 are symmetrically distributed on the two threaded surfaces. The side of the No. 3 slider 42 is fixedly connected with a No. 1 fixed plate 44, and the surface of the No. 1 fixed plate 44 is fixedly connected with an annular slider 45. The outside of the annular slider 45 is slidably connected with an annular slide rail 46. The surface of the annular slide rail 46 is threadedly connected with a No. 2 fixing knob 47.

When the clip 57 is pinched to drive the guide rod 55 to move, the fixing frame 58 is pressed against the guide rod 513. 5 is limited, so that the guide rod 55 pulls out the wedge-shaped limit block 513 along a straight line, and then the limit head 53 is fixedly connected with the limit seat 52, and the plug 511 can be directly inserted into the slot 59. During the insertion process of the plug 511, the wedge-shaped limit block 513 is pushed to move. When the plug 511 is plugged in place, the second spring 56 recovers its deformation and pushes the wedge-shaped limit block 513 to plug with the plug 511, so that the plug 511 is limited and fixed, and the limit seat 52 and the limit head 53 are fixed on the surface of the metal column at the bottom of the headrest.
[0029] The method of use and working principle of the device are as follows: the plug 511 at the end of the limit head 53 is plugged into the limit seat 52, and the limit seat 52 and the limit head 53 are fixed to the surface of the metal column at the lower part of the headrest of the main driver's seat or the co-driver's seat of the car, so as to fix the connecting mechanism 4 and the assembly mechanism 3, the support adjustment mechanism 2 and the drawing board mechanism 1 connected thereto. According to the use needs of the child, the No. 2 connecting outer plate 49 is slid along the No. 2 connecting inner plate 410 to adjust the height of the drawing board mechanism 1 behind the seat, and then the No. 1 adjusting screw 27 is rotated to make the No. 1 slider 26 slide along the No. 1 slide rail 25, driving the No. 2 connecting rod 24 and the No. 1 connecting rod 23 to move, changing the supporting angle of the No. 1 connecting rod 23 for the mounting plate 21, and then adjusting the angle of the drawing board mechanism 1 installed on the side of the mounting plate 21; The installation method of the magnetic drawing board body 11 and the mounting plate 21 being plugged in and out facilitates the removal and installation of the magnetic drawing board body 11. When the magnetic brush 12 falls or other items fall into the car during the child's graffiti, the magnetic drawing board body 11 is removed from the surface of the mounting plate 21, and the lighting strip 14 is turned on by the lighting switch 16, so that the lighting strip 14 illuminates the rear row in the car; When the first slide block 26 slides along the first slide rail 25, the second slide block 29 will simultaneously limit the movement of the first connecting rod 23 and the second connecting rod 24 along the second slide rail 28; Through the installation method of plugging the plug block 31 and the installation plug plate 32, when the drawing board mechanism 1 is not used inside the car, the plug block 31 is pulled out from the installation plug plate 32, so that the drawing board mechanism 1 and the supporting and adjusting mechanism 2 are independently disassembled; When the child does not doodle on the drawing board mechanism 1, the mounting plate 21 is placed in a horizontal position by turning the No. 1 adjusting screw 27. At this time, the surface of the drawing board mechanism 1 remains horizontal, and it can be used as a simple placement table in the car to increase the overall functionality. After the mounting plate 21 is adjusted to a horizontal state, the No. 2 fixing knob 47 is screwed out from the inside of the annular slider 45. At this time, the annular slider 45 slides along the annular slide rail 46, so that the mounting plate 21 and the drawing board mechanism 1 are in a vertical state behind the seat, reducing the overall impact on the rear space; When the vehicle is in a driving state, after being adjusted to a vertical state, the support adjustment mechanism 2 and the drawing board mechanism 1 are subjected to bumps, and at this time, the telescopic rod 36 and the first spring 37 produce telescopic deformation, so as to buffer the impact on the drawing board mechanism 1 and the support adjustment mechanism 2; When the device is not used in the car, the clip 57 is pinched to open the clip 57, and the clip 57 drives the connecting frame 54 to pull the guide rod 55 to move outward from the fixing frame 58, so that the wedge-shaped limit block 513 is disengaged from the plug 511, and the limit head 53 is pulled out from the side of the limit seat 52 to open the fixed position.
