[0061] An embodiment of the present application provides a writing board, which can be used for writing or drawing operations, and can also display an infinite mirror effect, with an ornamental function. The writing board has two mirrors, one of which is a total reflection mirror and the other is a half lens. By setting a light source, when a writing image is obtained by writing on either or both of the mirror surface of the half lens and the mirror surface of the total reflection mirror with a writing pen, the light provided by the light source illuminates the half lens and / or the total reflection mirror, so that the writing image can be reciprocally reflected between the two mirrors, thereby generating an infinite mirror effect.

[0062] Since the writing board can be used not only for users to write but also for users to draw, the writing board is sometimes also called a drawing board.

[0063] Figure 1 is a schematic structural diagram of the writing board 100 according to an embodiment of the present application in a closed state, Figure 2 is another schematic structural diagram of the writing board 100 according to an embodiment of the present application in a closed state, Figure 3 is a schematic structural diagram of the writing board 100 according to an embodiment of the present application in an unfolded state, Figure 4 is another schematic structural diagram of the writing board 100 according to an embodiment of the present application in an unfolded state, Figure 5 is an exploded structural diagram of the writing board 100 according to an embodiment of the present application, Figure 6 is another exploded structural diagram of the writing board 100 according to an embodiment of the present application, Figure 7 is a cross-sectional view of the writing board 100 according to an embodiment of the present application in a closed state.

[0064] As Figures 1 to 7 shown, the writing board 100 according to an embodiment of the present application includes a first carrier 10, a second carrier 20, a half lens 30, and a total reflection mirror 40. The first carrier 10 and the second carrier 20 can move relative to each other, and one of the first carrier 10 and the second carrier 20 can be unfolded or closed relative to the other. The first carrier 10 is provided with a first through hole 11, and the half lens 30 is installed in the first through hole 11. The total reflection mirror 40 is installed on the second carrier 20. The half lens 30 and the total reflection mirror 40 respectively provide a mirror surface, and the writing board 100 includes two mirror surfaces in total.

[0065] The first carrier 10 and the second carrier 20 are rotatably connected through a first rotating shaft 50, so that one of the first carrier 10 and the second carrier 20 can be unfolded and closed relative to the other. When the first carrier 10 rotates to be parallel to the second carrier 20 (the included angle between the two is approximately 0 degree), the first carrier 10 is buckled on the second carrier 20, so that the first carrier 10 is closed relative to the second carrier 20, and the writing board 100 is in Figure 1 and Figure 2 the closed state shown. When the first carrier 10 rotates to form a certain included angle with the second carrier 20, the first carrier 10 is opened relative to the second carrier 20, and the writing board 100 is inFigure 3 and Figure 4 the open state shown.

[0066] The semi-transparent mirror 30 is also known as a semi-reflective mirror, a semi-transmissive semi-reflective mirror, a two-sided mirror, a two-way mirror, a one-way perspective mirror, or a beam splitter. Figure 8 is a schematic diagram of the layer structure of the semi-transparent mirror 30. As Figure 8 shown, the semi-transparent mirror 30 is formed by uniformly vacuum plating a semi-transparent mirror metal film 32 on a transparent acrylic sheet 31, and then covering it with a transparent polymer protective film 33. The transparent polymer protective film 33 can protect the semi-transparent mirror metal film 32 from damage while ensuring the permeability of the mirror surface 30a of the mirror 30. The semi-transparent mirror 30 has both transmission and reflection functions, and the transmission and reflection ratios can be adjusted. The side where the transparent acrylic sheet 31 is located is the mirror surface 30a of the semi-transparent mirror, and the side where the transparent polymer protective film 33 is located is the back surface 30b of the semi-transparent mirror.

[0067] Please continue to refer to Figure 5 , the through hole formed in the first carrier 10 is a stepped hole, which is convenient for fixing the semi-transparent mirror 30. For example, the semi-transparent mirror 30 can be bonded to the stepped portion of the stepped hole by gluing. As Figure 8 shown, when the semi-transparent mirror 30 is installed in the through hole of the first carrier 10, the mirror surface 30a of the semi-transparent mirror faces the total reflection mirror 40, and the back surface 30b of the semi-transparent mirror is exposed on the outer surface of the writing board 100. Selecting the back surface 30b of the semi-transparent mirror rather than the mirror surface 30a of the semi-transparent mirror to be exposed on the outer surface of the writing board 100 can protect the mirror surface 30a of the semi-transparent mirror.

[0068] In some other embodiments, the semi-transparent mirror 30 can also be fixed to the first carrier 10 by a component for installing the semi-transparent mirror. In the embodiments of the present application, the first carrier may not form the first through hole 11, and the structure of the first carrier only needs to meet the requirement that the image on the total reflection mirror 40 can be seen through the semi-transparent mirror 30 when the writing board is in the closed state.

[0069] The total reflection mirror 40 is also known as a one-way mirror. Figure 9 is a schematic diagram of the layer structure of the total reflection mirror 40. As Figure 9 shown, the total reflection mirror 40 is formed by plating a mirror metal film 42 on a transparent acrylic sheet 41, and then covering it with a protective back paint 43 to protect the mirror metal film 42. The side where the acrylic sheet 41 is located is the mirror surface 40a of the total reflection mirror, and the side where the protective back paint 43 is located is the back surface 40b of the total reflection mirror. The total reflection mirror 40 only reflects light.

[0070] The semi-transparent mirror 30 and the total reflection mirror 40 use transparent acrylic sheets as the mirror surfaces, which are light and safe. Of course, the semi-transparent mirror 30 and the total reflection mirror 40 can also use glass sheets or other transparent substrates to replace the transparent acrylic sheets.

[0071] In the specific embodiment shown in the figure, the shapes of the semi-transmissive mirror 30 and the total reflection mirror 40 are rectangular. In other embodiments, the shapes of the semi-transmissive mirror 30 and the total reflection mirror 40 can also be circular, rhombic, heart-shaped, etc., and the present application does not limit this.

[0072] As Figure 7 shown, when the total reflection mirror 40 is installed on the second carrier 20, the back surface 40b of the total reflection mirror is fixed to the second carrier 20, and the mirror surface 40a of the total reflection mirror faces the semi-transmissive mirror 30. As Figure 3 and Figure 4 shown, when one of the first carrier 10 and the second carrier 20 is unfolded relative to the other, it is equivalent to opening the semi-transmissive mirror 30 relative to the total reflection mirror 40, and the writing board 100 is in an open state, and the mirror surface 40a of the total reflection mirror is exposed. At this time, a writing image can be obtained by writing on either or both of the mirror surface 30a of the semi-transmissive mirror and the mirror surface 40a of the total reflection mirror with a writing pen. The content of the writing image can be text, pattern, or a combination of text and pattern, etc. The writing pen is preferably a fluorescent pen.

[0073] The writing board 100 further includes a light source 60. The light source 60 can be arranged on the first carrier 10 or the second carrier 20, or the light source 60 can be arranged on both the first carrier 10 and the second carrier 20. The present application does not limit this, as long as when the first carrier 10 is closed relative to the second carrier 20, the light provided by the light source 60 can illuminate the semi-transmissive mirror 30 and / or the total reflection mirror 40.

[0074] When the writing pen is a fluorescent pen, the color rendering performance of the fluorescent pen and the light provided by the light source form a synergistic effect, with prominent color performance and good display effect.

[0075] Please continue to refer to Figure 7 , when the first carrier 10 is closed relative to the second carrier 20, the writing board 100 is in a closed state, the mirror surface 30a of the semi-transmissive mirror and the mirror surface 40a of the total reflection mirror face each other and there is a distance d between the two mirror surfaces. When the light source 60 provides light to illuminate the semi-transmissive mirror 30 and / or the total reflection mirror 40, the writing image is repeatedly reflected between the semi-transmissive mirror 30 and the total reflection mirror 40, so as to generate multiple spaced reflection images backward on the total reflection mirror 40 to produce an infinite mirror (i.e., a thousand-layer mirror) effect.

[0076] The light source 60 is arranged on the second carrier 20. Figure 10 is a partial structural schematic diagram of the second carrier 20. Please refer to Figure 5 , Figure 7 and Figure 10, the light source 60 includes a light-emitting member 64, and the light-emitting member 64 can be disposed on one side or multiple sides of the total reflection mirror 40 to illuminate the total reflection mirror 40 with light. In the specific embodiment shown in the figure, the light-emitting member 64 is disposed on one side at the bottom of the total reflection mirror 40. The light-emitting member 64 includes a plurality of light-emitting units 641, such as LED lights, and the plurality of light-emitting units 641 are arranged along the side of the total reflection mirror 40. As shown in the figure, they are arranged along the bottom side of the total reflection mirror 40. When the light-emitting member 64 can be disposed on one side or multiple sides of the total reflection mirror 40, the light can illuminate the mirror body of the total reflection mirror 40, so that the writing image is repeatedly reflected between the semi-transparent mirror 30 and the total reflection mirror 40, and a better effect of generating multiple spaced reflection images backward on the total reflection mirror 40 can be achieved.

[0077] In some embodiments, the position of the light-emitting member 64 can also be arranged so that the light illuminates the mirror surface of the semi-transparent mirror 30 and / or the total reflection mirror 40.

[0078] The second carrier 20 is provided with a first accommodation cavity 211 with an opening facing the side of the total reflection mirror, and the light emitted by the light-emitting member 64 exits from the opening facing the side of the total reflection mirror 40.

[0079] Figure 11 It is a partial exploded structural schematic diagram of the second carrier 20. As Figure 11 shown, the light source 60 includes a circuit board 61, a power supply 62, a switch 63, and a light-emitting member 64. The power supply 62, the switch 63, and the light-emitting member 64 are respectively electrically connected to the circuit board 61. The second carrier 20 includes a first housing 21 and a second housing 22 that are buckled to each other. The total reflection mirror 40 is fixed to the first housing 21. The first housing 21 is provided with the aforementioned first accommodation cavity 211, and the light-emitting member 64 is disposed in the first accommodation cavity 211. The second housing 22 is provided with a second accommodation cavity 221, and the circuit board 61 and the power supply 62 are disposed in the second accommodation cavity 221.

[0080] The circuit board 61 can be a Printed Circuit Board (PCB).

[0081] The power supply 62 provides electrical energy for the circuit board 61 and the light-emitting member 64. The power supply 62 is a rechargeable battery. A charging interface 611 and a charging indicator light 612 are provided on the circuit board 61 (as Figure 3 shown), and the charging interface 611 and the charging indicator light 612 are exposed outside the second housing 22, which is convenient for users to operate and observe. The power supply 62 can also be a disposable battery, and it can be replaced when the power of the power supply 62 is exhausted.

[0082] The switch 63 can be in various forms, including but not limited to touch switches, button switches, rotary switches, toggle switches, slide switches, voice-activated switches, light-activated switches, remote control switches, etc. In the embodiments of the present application, a touch switch is adopted. The first housing 21 is provided with a second through hole 212, and the total reflection mirror 40 is provided with a third through hole 44. The second through hole 212 and the third through hole 44 are communicated. The switch 63 passes through the second through hole 212 and the third through hole 44 and is exposed outside the total reflection mirror 40, so that after the user writes on the total reflection mirror 40, the switch 63 can be directly operated to trigger the light-emitting member 64 to emit light, which is convenient for the user to operate. When the switch 63 is touched for the first time, the light-emitting member 64 is turned on to be in a light-emitting state; when the switch 63 is touched again, the light-emitting member 64 is in a closed state to stop emitting light.

[0083] The circuit board 61 can also control the light-emitting member 64 to emit light according to different light-emitting modes. The light-emitting modes include but not limited to continuous light emission, breathing light emission, sequential light emission, gradient light emission, color alternating light emission, etc.

[0084] As Figure 2 、 Figures 4 to 7 shown, the second carrier 20 further includes a third housing 23. There is a spacing between the third housing 23 and the first housing 21. The total reflection mirror 40 includes an opposite first end 40c and a second end 40d. The first end 40c of the total reflection mirror is fixed to the third housing 23, and the second end 40d of the total reflection mirror is fixed to the first housing 21. The part of the second carrier 20 for fixing the total reflection mirror 40 is set as the spaced-apart first housing 21 and third housing 23, which reduces the material cost, reduces the product weight, improves the portability and is convenient for operation.

[0085] The first carrier 10 is rotatably connected to the third housing 23 of the second carrier 20.

[0086] The total reflection mirror 40 is fixed to the first housing 21 and the third housing 23 by bonding. Both the first housing 21 and the third housing 23 are provided with one or more glue filling holes 24. The glue filling holes 24 are used to accommodate the adhesive for bonding the total reflection mirror 40 and the first housing 21 or bonding the total reflection mirror 40 and the second housing 22. When installing the total reflection mirror 40, inject the adhesive into the glue filling holes 24, align the total reflection mirror 40 with the first housing 21 and the third housing 23 and paste them together. The bonding and fixing method reduces the number of parts and is convenient for operation. Of course, the total reflection mirror 40 can also be fixed to the second carrier 20 by welding, screwing, riveting, clamping, etc.

[0087] For the convenience of positioning during the installation of the total reflection mirror 40, in the first housing 21 and the total reflection mirror 40, one of them is provided with a positioning groove 213, and the other is provided with a positioning protrusion 45. The positioning protrusion 45 is embedded in the positioning groove 213. As Figure 5 and Figure 10As shown, in the illustrated embodiment, two positioning grooves 213 are provided at both ends of the bottom of the first housing 21, and two positioning protrusions 45 are provided at positions corresponding to the positioning grooves 213 at both ends of the bottom of the total reflection mirror 40.

[0088] As Figure 2 , Figures 4 to 7 shown, the writing board 100 further includes a bracket 70, and the bracket 70 is connected to the first carrier 10 or the second carrier 20. The bracket 70 includes opposite first end 70a and second end 70b, and the first end 70a of the bracket is rotatably connected to the second carrier 20 through a rotating part 71. Specifically, the rotating part 71 of the bracket can be rotatably connected to the third housing 23 in the second carrier 20 through a second rotating shaft.
