[0044] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments, and the following embodiments do not limit the invention involved in the claims. In addition, all combinations of the features described in the embodiments are not necessarily required for the solution of the invention.

[0045] The principle and structure of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0046] Embodiment 1

[0047] As Figure 1 、 2 shown, an electronic handwriting device includes a handwriting board 1 and a protective case 2. The handwriting board 1 is an electronic device that allows users to write, draw or perform other inputs on the board surface with a handwriting pen. The material of the protective case 2 can be leather material, also known as a leather case or protective cover.

[0048] As Figure 4 、 5 、6 shown, the protective case 2 includes a housing. The housing includes a back plate 21 for connecting to the back 11 of the handwriting board and a face cover 22 for covering the writing surface 12 of the handwriting board 1. The face cover 22 is rotatably connected to the back plate 21. The rotation of the face cover 22 relative to the back plate 21 causes the protective case 2 to open or close. In this embodiment, the housing is a plate body, and a crease 23 is provided in the middle of the plate body. The face cover 22 and the back plate 21 are folded and rotated through the crease 23, so that a flat plate is formed when the protective case 2 is opened.

[0049] As Figure 3 shown, it further includes a notebook 3 on the inner side surface of the face cover. The notebook 3 is a paper writing book, and the notebook 3 is detachably connected to the inner side surface of the housing. When the protective case 2 is opened, the notebook 3 and the handwriting board 1 are juxtaposed on the inner side surface of the housing, so that either the electronic handwriting board 1 can be used for writing or traditional paper writing can be used; when the protective case 2 is closed, the notebook 3 is clamped between the handwriting board 1 and the face cover, thereby realizing storage.

[0050] As Figure 7As shown, the writing tablet 1 of this embodiment is detachably connected to the inner side of the back plate 21 by Velcro. The suede surface 41 of the Velcro is provided on the back of the writing tablet 1, and the hook surface 42 of the Velcro is provided on the inner side of the back plate 21. "Velcro" is a common hook-and-loop fastener, also known as nylon fastener or Velcro, which is a fastening system composed of two parts made of different materials. One part consists of tiny hooks, namely the hook surface 42, and the other part consists of soft loops, namely the suede surface 41. When the two parts are pressed together, the hooks and loops grip each other, thus producing an adhesive effect. The characteristics of Velcro are convenient to use, durable and can be reused multiple times. The suede surface 41 of the Velcro is provided on the back of the writing tablet 1 mainly to prevent damage to the contact objects (such as textile clothes) while meeting the frictional resistance when the user detaches the writing tablet 1 from the back plate 21.

[0051] As Figure 3 shown, the notebook 3 of this embodiment includes a binder 31 and writing paper 32 provided on the binder 31. The binder 31 is made of ferromagnetic material, and a magnet for adsorbing the binder 31 is provided on the housing. The magnet is three built-in magnets 5 arranged vertically. That is, the notebook 3 is a binder notebook 3. A binder notebook 3 is a notebook 3 in which papers can be added, removed or rearranged during use. The binder 31 can be opened and closed, enabling the user to easily add or remove papers. The material of the binder 31 in this embodiment is iron that can be attracted by the built-in magnet 5, so that the binder 31 of the notebook 3 is fixed relative to the housing. Of course, the notebook 3 can also use a plastic binder 31 and adopt a detachable structure such as Velcro to achieve detachable connection. In the usage scenario where the notebook 3 is not needed, the notebook 3 can be detached from the housing without affecting the use of the writing tablet 1 and the housing's storage of the writing tablet 1.

[0052] As Figure 4 shown, storage holes 24 for storing a stylus and a data cable 10 can also be provided on the face cover 22 to facilitate the storage of common components such as the stylus and the data cable 10. The leather case is equivalent to a freely matched base, which not only includes holes for storing the stylus and the data cable 10, but is also an adhesion base for the notebook 3 and the writing tablet 1.

[0053] As Figure 7As shown in the figure, the graphics tablet 1 includes a film 121, a fixed cover 111, a silicone button 13, a PCBA board 14, and a cover plate 15; the film 121 serves as the handwriting or drawing area, the fixed cover 111 serves as the support of the product, the silicone button 13 is used for device mode switching, the PCBA board 14 provides digital handwriting or hand-drawing functions, and at the same time interacts with the terminal device 9 through a wire. The cover plate 15 is pasted on the PCBA board 14, mainly for covering and decorating the product part.

[0054] Cancel the product bottom case and replace it with a bottom cover made of a common plastic sheet on the market; this not only reduces the investment in R & D mold costs, but also reduces the unit price of the product. Reduce the fixing screws of the front and bottom cases, and use the back glue of the bottom cover to paste on the PCBA, which greatly improves the efficiency in terms of personnel operation. Cancel the common plastic buttons on the market for the button material and use the silicone button 13 instead. Reduce the investment in R & D mold costs. The silicone hot pressing mold is more economical and practical than the plastic mold, and the feel is relatively more comfortable.

[0055] This graphics tablet 1 can be combined with intelligent terminal devices 9 such as mobile phones and thus applied in different application scenarios. For example, there can be the following three combinations:

[0056] As Figure 8 shown, Combination 1 (simple matching): The terminal device 9 is directly connected to the graphics tablet through the data cable 10. The simple matching is suitable for use in relatively small home spaces.

[0057] As Figure 9 shown, Combination 2 (standard matching): The terminal device 9 is directly connected to the graphics tablet with a protective case 2 through the data cable 10. The combination with the protective case 2 is suitable for use outdoors and during the journey of taking the bus or subway.

[0058] As Figure 10 shown, Combination 3 (full set matching): The terminal device 9 is directly connected to the graphics tablet with a protective case 2 and a notepad through the data cable 10. This combination is suitable for use in work such as office, study, and meetings.

[0059] Embodiment 2

[0060] As Figure 11 、 12As shown, different from the above embodiments, the graphics tablet 1 is detachably connected to the inner side of the backplane 21 through a first magnetic attraction component. The first magnetic attraction component includes several magnets distributed on the back of the graphics tablet 1 and magnetic members arranged on the backplane 21 corresponding to the adsorption of the magnets. The first magnetic attraction component includes several pairs of magnets distributed on the back of the graphics tablet 1 and magnetic members arranged on the backplane 21 corresponding to the adsorption of the magnet pairs. Each magnet pair includes two magnets arranged side by side with opposite magnetic poles. The magnetic member is a magnet the same as the magnet on the back of the graphics tablet 1. The magnet is arranged in the silica gel pad 6. The magnet in this embodiment is an embedded magnet 7. Relative to the middle of the back, the outer embedded magnets 7 of each magnet pair have the same polarity. That is, the two embedded magnets 7 of each magnet pair are of different poles. Here, the outer edge is the N pole and the inner edge is the S pole. The purpose is to use the repulsion of like poles and attraction of opposite poles of magnets to quickly, automatically, accurately and position the graphics tablet 1 within a small range. Of course, other combination schemes can also be adopted. For example, each embedded magnet of the same pole can be embedded in the silica gel pad 6 on the back of the graphics tablet 1, which can also meet the magnetic attraction matching requirements.

[0061] As Figure 13 shown, an alloy sheet 8 for shielding the magnetic field of the magnet is arranged between the magnet and the graphics tablet 1.

[0062] We know that magnets generate magnetic fields. Since the graphics tablet 1 also uses electromagnetic induction technology, the magnetic field of the magnet will affect the writing of the graphics tablet 1. To solve this problem, the silica gel pad 6 is pasted close to the four corners of the graphics tablet 1, as far as possible from the handwriting or hand-drawing area, and an alloy sheet 8 with a magnetic field shielding function is arranged between the magnet and the graphics tablet 1, so as to effectively attenuate the influence of the magnet magnetic field on the function of the graphics tablet 1.

[0063] Embodiment Three

[0064] As Figure 14 、 15 shown in FIGS. 16, different from the above embodiments, the first magnetic attraction component includes a magnet arranged on the backplane 21 and a silicon steel sheet 16 fixed on the back of the graphics tablet. The silicon steel sheet is fixed on the inner side of the housing of the graphics tablet. In this embodiment, four embedded magnets 7 are fixed at the four corners of the backplane, and the silicon steel sheet is arranged between the cover plate of the graphics tablet and the PCBA board. Since the PCBA board needs to be fixed to the fixed cover with screws, making full use of the property that the magnet attracts the silicon steel sheet, the embedded magnets are built in the four corners of the backplane, and the magnetic attraction stability is ensured. The magnets need to use N52 neodymium iron boron strong magnets. Corresponding to the fixing screw 17 of the PCBA, the silicon steel sheet is provided with clearance holes so that the fixing bolt can pass through, which is also beneficial to the positioning and fixing of the silicon steel sheet.

[0065] Embodiment Four

[0066] As Figure 17 , 18 shown, different from the above embodiments, the magnets are arranged at the four corners of the back 11 of the writing tablet, a velveteen surface 41 of a magic tape is arranged in the middle of the back of the writing tablet, and a hook surface 42 of a magic tape corresponding to the velveteen surface is arranged on the back plate 21. For example, in this embodiment, on the basis of the second embodiment, a heart-shaped hook surface 42 of a magic tape is arranged in the middle of the back of the writing tablet. This solution can reduce the number of magic tapes, only arrange magic tapes in the middle area of the back of the writing tablet, and arrange silica gel pads 6 at the four corners to assist in balancing. Because the use of silica gel foot pads provides a more friendly user experience - anti-slip and better stability, while also meeting the requirements of bonding and disassembly of the magic tape.
