[0021] In some embodiments, the total reflection mirror is fixed to the first housing and the third housing by adhesive bonding.

[0022] In some embodiments, both the first housing and the third housing are provided with one or more glue-filling holes for accommodating adhesives for bonding the total reflection mirror to the first housing or bonding the total reflection mirror to the second housing.

[0023] In some embodiments, one of the first housing and the total reflection mirror is provided with a positioning groove, and the other is provided with a positioning protrusion, the positioning protrusion being embedded in the positioning groove.

[0029] In some embodiments, when the writing tablet is placed with the support facing down in the first state, the bottom of the support is flush with the bottom of the second carrier.

[0030] In some embodiments, the first end of the bracket is rotatably connected to the second carrier via a rotating part;

[0031] In the first state, when the writing tablet is placed with the support facing down, the bottom of the rotating part is the bottom of the support, and the bottom of the second housing is the bottom of the second carrier.

[0032] In some embodiments, the writing pen is a highlighter, and the light source provides light to illuminate the written image.

[0033] This embodiment of the application incorporates two mirrors within a writing pad. One mirror is a total reflection mirror, and the other is a semi-reflective mirror. When the writing pad is closed, a gap exists between the two mirrors. By providing a light source, when a writing pen writes on either or both of the semi-reflective mirror and the total reflection mirror, the light from the light source illuminates the semi-reflective mirror and / or the total reflection mirror, causing the written image to reflect back and forth between the two mirrors, thus creating an infinite mirror effect.

[0061] This application provides a writing tablet that can be used for writing or drawing, and can also display an infinite mirror effect, providing a visual appeal. The writing tablet has two mirrors, one of which is a total reflection mirror and the other is a semi-transparent mirror. By providing a light source, when a writing pen writes on either or both of the semi-transparent mirror and the total reflection mirror, the light from the light source illuminates the semi-transparent mirror and / or the total reflection mirror, causing the written image to reflect back and forth between the two mirrors, thus producing an infinite mirror effect.

[0062] Because writing tablets can be used for writing and drawing, they are sometimes also called drawing tablets.

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

[0064] like Figures 1 to 7 As shown, the writing tablet 100 of this embodiment includes a first carrier 10, a second carrier 20, a semi-transparent mirror 30, and a total reflection mirror 40. The first carrier 10 and the second carrier 20 are movable 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 has a first through hole 11, and the semi-transparent mirror 30 is installed in the first through hole 11. The total reflection mirror 40 is installed on the second carrier 20. The semi-transparent mirror 30 and the total reflection mirror 40 each provide a mirror surface, and the writing tablet 100 includes a total of two mirror surfaces.

[0065] The first carrier 10 and the second carrier 20 are rotatably connected via a first rotating shaft 50, allowing one of them to unfold and close relative to the other. When the first carrier 10 rotates to be parallel to the second carrier 20 (the included angle is approximately 0 degrees), the first carrier 10 engages with the second carrier 20, closing the first carrier 10 relative to the second carrier 20, and the writing pad 100 is in a position... Figure 1 and Figure 2 The first carrier 10 is in the closed state shown. When the first carrier 10 rotates to an angle with the second carrier 20, the first carrier 10 opens relative to the second carrier 20, and the writing tablet 100 is in the closed state. Figure 3 and Figure 4 The open state is shown.

[0066] The semi-transparent mirror 30 is also known as a semi-reflective mirror, a semi-transparent mirror, a double-sided mirror, a two-way mirror, a one-way perspective mirror, or a beam splitter. Figure 8 This is a schematic diagram of the layer structure of the semi-transparent mirror 30, as shown below. Figure 8 As shown, the semi-transparent mirror 30 is constructed by uniformly vacuum-plating a semi-transparent mirror metal film 32 onto a transparent acrylic sheet 31, and then covering it with a transparent polymer protective film 33. The transparent polymer protective film 33 protects the semi-transparent mirror metal film 32 from damage while ensuring the transparency of the mirror surface 30a. The semi-transparent mirror 30 has both transmission and reflection functions, and the transmission / reflection ratio is adjustable. The side containing the transparent acrylic sheet 31 is the mirror surface 30a of the semi-transparent mirror, and the side containing the transparent polymer protective film 33 is the back surface 30b of the semi-transparent mirror.

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

[0068] In other embodiments, the semi-transparent mirror 30 can also be fixed to the first carrier 10 by a component for mounting the semi-transparent mirror. In this embodiment, the first carrier may not have the first through hole 11, and the structure of the first carrier is sufficient to allow the image on the total reflection mirror 40 to 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 This is a schematic diagram of the layer structure of the total reflection mirror 40, as shown below. Figure 9 As shown, the total reflection mirror 40 is made by electroplating a layer of mirror metal film 42 onto a transparent acrylic sheet 41, and then covering it with a protective back coating 43 to protect the mirror metal film 42. The side containing the acrylic sheet 41 is the mirror surface 40a of the total reflection mirror, and the side containing the protective back coating 43 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 surface, which are lightweight and highly safe. Of course, the semi-transparent mirror 30 and the total reflection mirror 40 can also use glass sheets or other transparent substrates as the substrate instead of transparent acrylic sheets.

[0071] In the specific embodiment shown in the figure, the semi-transparent mirror 30 and the total reflection mirror 40 are rectangular in shape. In other embodiments, the semi-transparent mirror 30 and the total reflection mirror 40 may also be circular, prismatic, heart-shaped, etc., and this application does not limit them in this way.

[0072] like Figure 7 As shown, when the total reflection mirror 40 is mounted 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-transparent mirror 30. Figure 3 and Figure 4 As 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-transparent mirror 30 relative to the total reflection mirror 40. The writing board 100 is in the 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-transparent mirror and the mirror surface 40a of the total reflection mirror with a writing pen. The content of the writing image can be text, patterns, or a combination of text and patterns, etc. A highlighter pen is preferably used as the writing pen.

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

[0074] When a highlighter is used as a writing pen, the highlighter's color rendering performance and the light provided by the light source work together to create a synergistic effect, resulting in outstanding color performance and good display effect.

[0075] Please continue reading. Figure 7 When the first carrier 10 is closed relative to the second carrier 20, the writing pad 100 is in a closed state, and the mirror surface 30a of the semi-transparent mirror and the mirror surface 40a of the total reflection mirror are opposite each other with a distance d between the two mirror surfaces. When the light source 60 provides light to illuminate the semi-transparent mirror 30 and / or the total reflection mirror 40, the written image is reflected back and forth between the semi-transparent mirror 30 and the total reflection mirror 40, thereby producing multiple spaced reflected images on the total reflection mirror 40 to produce an infinite mirror (i.e., a thousand-layer mirror) effect.

[0076] The light source 60 is located on the second carrier 20. Figure 10 This is a partial structural schematic diagram of the second carrier 20. Please refer to it as well. Figure 5 , Figure 7 and Figure 10The light source 60 includes a light-emitting element 64, which can be disposed on one or more sides of the total reflection mirror 40 to illuminate the total reflection mirror 40. In the specific embodiment shown in the figure, the light-emitting element 64 is disposed on the bottom side of the total reflection mirror 40. The light-emitting element 64 includes multiple light-emitting units 641, such as LEDs, which are arranged along the side of the total reflection mirror 40, as shown in the figure, along the bottom side of the total reflection mirror 40. When the light-emitting element 64 is disposed on one or more sides of the total reflection mirror 40, the light can illuminate the mirror body of the total reflection mirror 40, resulting in a better effect where the written image is reflected back and forth between the semi-transparent mirror 30 and the total reflection mirror 40, producing multiple spaced reflected images on the total reflection mirror 40.

[0077] In some embodiments, the position of the light-emitting element 64 may be arranged such that 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 receiving cavity 211 with an opening facing the side of the total reflection mirror, and the light emitted by the light-emitting element 64 exits from the side of the opening facing the total reflection mirror 40.

[0079] Figure 11 This is a schematic diagram of a partially disassembled structure of the second carrier 20. (See attached diagram.) Figure 11 As shown, the light source 60 includes a circuit board 61, a power supply 62, a switch 63, and a light-emitting element 64. The power supply 62, switch 63, and light-emitting element 64 are electrically connected to the circuit board 61. The second carrier 20 includes a first housing 21 and a second housing 22 that are interlocked. The total reflection mirror 40 is fixed to the first housing 21, and the first housing 21 has the aforementioned first receiving cavity 211, in which the light-emitting element 64 is disposed. The second housing 22 has a second receiving cavity 221, in which the circuit board 61 and the power supply 62 are disposed.

[0080] Circuit board 61 can be a printed circuit board (PCB).

[0081] Power supply 62 provides power to circuit board 61 and light-emitting element 64. Power supply 62 is a rechargeable battery. Circuit board 61 is provided with charging interface 611 and charging indicator light 612 (e.g., ...). Figure 3 As shown, the charging port 611 and charging indicator light 612 are exposed on the second housing 22 for easy user operation and observation. The power supply 62 can also be a disposable battery, which can be replaced when the power supply 62 is depleted.

[0082] The switch 63 can take various forms, including but not limited to touch switches, push-button switches, rotary switches, toggle switches, slide switches, voice-activated switches, light-activated switches, and remote control switches. In this embodiment, a touch switch is used. The first housing 21 has a second through hole 212, and the total reflection mirror 40 has a third through hole 44. The second through hole 212 and the third through hole 44 are connected. The switch 63 passes through the second through hole 212 and the third through hole 44 and is exposed on the total reflection mirror 40, so that the user can directly operate the switch 63 to trigger the light-emitting element 64 to emit light after writing on the total reflection mirror 40, facilitating user operation. When the switch 63 is touched for the first time, the light-emitting element 64 is turned on and in a light-emitting state; when the switch 63 is touched again, the light-emitting element 64 is turned off and stops emitting light.

[0083] The circuit board 61 can also control the light-emitting element 64 to emit light according to different light-emitting modes, including but not limited to continuous light emission, breathing light emission, sequential light emission, gradual light emission, and color alternating light emission.

[0084] like Figure 2 , Figures 4 to 7 As shown, the second carrier 20 also includes a third housing 23, which has a gap with the first housing 21. The total reflection mirror 40 includes a first end 40c and a second end 40d opposite to each other. 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. By setting the portion of the second carrier 20 used to fix the total reflection mirror 40 to the spaced-apart first housing 21 and third housing 23, material costs are reduced, product weight is reduced, portability is improved, and operation is convenient.

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

[0086] The total reflection mirror 40 is fixed to the first housing 21 and the third housing 23 by adhesive bonding. Both the first housing 21 and the third housing 23 are provided with one or more glue-filling holes 24, which are used to accommodate adhesive for bonding the total reflection mirror 40 to the first housing 21 or to the total reflection mirror 40 and the second housing 22. When installing the total reflection mirror 40, adhesive is injected into the glue-filling holes 24, and the total reflection mirror 40 is aligned with and bonded to the first housing 21 and the third housing 23. Adhesive bonding reduces the number of parts and facilitates operation. Of course, the total reflection mirror 40 can also be fixed to the second carrier 20 by welding, screwing, riveting, snap-fitting, etc.

[0087] To facilitate positioning during the installation of the total reflection mirror 40, a positioning groove 213 is provided in one of the first housing 21 and the total reflection mirror 40, and a positioning protrusion 45 is provided in the other, with the positioning protrusion 45 fitting into the positioning groove 213. Figure 5 and Figure 10As shown in the figure, in the embodiment shown, 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 the positions corresponding to the positioning grooves 213 at both ends of the bottom of the total reflection mirror 40.

[0088] like Figure 2 , Figures 4 to 7 As shown, the writing tablet 100 also includes a support 70, which is connected to either the first carrier 10 or the second carrier 20. The support 70 includes a first end 70a and a second end 70b, with the first end 70a rotatably connected to the second carrier 20 via a rotating part 71. Specifically, the rotating part 71 of the support can be rotatably connected to the third housing 23 in the second carrier 20 via a second rotating shaft.

[0089] The support 70 can switch between a first state and a second state by rotating relative to the second carrier 20.

[0090] Figures 1 to 4 As shown, bracket 70 is in the first, unopened state. Please also refer to [the relevant documentation / reference]. Figure 5 and Figure 6 When the support 70 is in the first state, the second end 70b of the support is close to the second carrier 20, and the support 70 is parallel to the second carrier 20. Figure 1 and Figure 2 As shown, if the first carrier 10 is closed relative to the second carrier 20, and the bracket 70 is not opened, the writing tablet 100 can be placed flat on the supporting surface (with the back of the semi-transparent lens 30b facing upwards), or the writing tablet 100 can be stored, for example, in a storage bag or drawer. Figure 3 and Figure 4 As shown, if the first carrier 10 is unfolded relative to the second carrier 20, but the support 70 is not opened, the writing tablet 100 can place the support 70 and the second carrier 20 on the support surface (with the mirror surface 40a of the total reflection mirror facing upwards), similar to the placement of a laptop computer. At this time, the user can write on the mirror surface 40a of the total reflection mirror and / or the mirror surface 30a of the semi-reflective mirror.

[0091] Figure 12 This is a schematic diagram of the writing tablet 100 in the unfolded state and the support 70 in the open, according to an embodiment of this application. Figure 13 This is another structural schematic diagram of the writing tablet 100 in the unfolded state and the support 70 in the open, according to an embodiment of this application. Figure 14 This is a side view of the writing tablet 100 in the unfolded state and the support 70 in the open, according to an embodiment of this application. Figure 12 and Figure 13 As shown, the support 70 is in the open second state. In the second state, the second end 70b of the support is away from the second carrier 20 and has an angle α with the second carrier 20 (e.g., ...). Figure 14 As shown, the writing board 100 can be placed on the support surface via the second carrier 20 and the bracket 70.

[0092] Please return to the reference. Figure 7 , Figure 7 The middle support 70 is in the first state, and the writing tablet 100 is placed with the support 70 facing downwards. At this time, the bottom of the support 70 is flush with the bottom of the second carrier 20, so that the writing tablet 100 can be placed stably on the support surface. In this state, the bottom of the rotating part 71 is the bottom of the support 70, and the bottom of the second housing 22 is the bottom of the second carrier 20, that is, the bottom of the rotating part 71 is flush with the bottom of the second housing 22.

[0093] Finally, the use of the writing tablet 100 in this embodiment will be described.

[0094] First method of use: When the writing board is in position 100... Figure 1 and Figure 2 In the closed state shown, the first carrier 10 is unfolded relative to the second carrier 20 (that is, the semi-transparent mirror 30 is unfolded relative to the total reflection mirror 40), so that the writing board 100 is in a closed position. Figure 3 and Figure 4 In the unfolded state shown, the rear support 70 of the writing pad 100 is not open. The support 70 and the second housing 22 can be placed on the support surface, and the writing pen can be used to write on the mirror surface 40a of the total reflection mirror. After writing and obtaining the written image, the switch 63 is operated to turn on the light, and then the first carrier 10 is closed relative to the second carrier 20 (that is, the semi-transparent mirror 30 is closed relative to the total reflection mirror 40), so that the writing pad 100 is in the position shown. Figure 1 and Figure 2 The closed state shown allows for viewing the infinite mirror effect through the semi-transparent mirror 30.

[0095] The second way to use it: When the writing board is in position 100... Figure 1 and Figure 2 In the closed state shown, the first carrier 10 is unfolded relative to the second carrier 20 (that is, the semi-transparent mirror 30 is unfolded relative to the total reflection mirror 40), and the bracket 70 is opened, so that the writing tablet 100 is in the closed position. Figures 12 to 14 With the support 70 in the unfolded and open state shown, place the support 70 and the second housing 22 of the second carrier 20 on the support surface, and write on the mirror surface 40a of the total reflection mirror using a writing pen. After writing and obtaining the written image, operate the switch 63 to turn on the light, and then close the first carrier 10 relative to the second carrier 20 (that is, close the semi-transparent mirror 30 relative to the total reflection mirror 40), so that the writing tablet 100 is in the position shown. Figure 15 The state shown indicates that the infinite mirror effect can be viewed through the translucent mirror 30.
