Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] See attached document Figure 1-7 This invention relates to a handwriting tablet calculator that supports intelligent input.

[0031] This intelligent input-enabled handwriting tablet calculator includes: a calculator body 1 for numerical calculations, on which a first controller 13 and a display screen 11 are mounted, the display screen 11 being electrically connected to the first controller 13; a handwriting tablet body 2 connected to the calculator body 1; a stylus 3 for writing on the handwriting tablet body 2; a data acquisition module 31 for collecting note traces, the data acquisition module 31 being mounted on the stylus 3 or the handwriting tablet body 2; and a recognition module 5. Both the first controller 13 and the data acquisition module 31 are electrically connected to the recognition module 5. The recognition module 5 receives the note traces collected by the data acquisition module 31 and generates calculation information from the note traces. The first controller 13 receives the calculation information transmitted by the recognition module 5, performs calculations on the calculation information, and then transmits the calculation result to the display screen 11 for display.

[0032] This invention utilizes a data acquisition module 31 configured on the handwriting tablet body 2 or the stylus 3 to collect the note trajectory written on the handwriting tablet in real time. In conjunction with the recognition module 5 and the first controller 13, the note trajectory is used to generate calculation information, which is then processed to calculate the information written by the user on the handwriting tablet body 2 and obtain the result. Finally, the result is displayed on the screen 11, allowing the user to directly obtain the result without having to input the calculation information again on the calculator body 1. This eliminates the need for user operation, greatly facilitating user use and enabling users to verify the results after practicing the calculations.

[0033] In one embodiment, the acquisition module 31 is a camera module or an inertial sensor. The acquisition module 31 is mounted on the stylus 3, which is equipped with a first wireless module 33 and a second controller 32. The calculator body 1 is equipped with a second wireless module 16 for communicating with the first wireless module 33.

[0034] When the recognition module 5 is mounted on the stylus 3, the recognition module 5 is electrically connected to the second main controller 32, such as... Figure 5 As shown, the identification module 5, the first wireless module 33, and the second controller 32 can be located on the same circuit board; or, when the identification module 5 is installed on the calculator body 1, the first main controller 13 is connected to the second wireless module 16 through the identification module 5, as shown. Figure 6 As shown, the first main controller 13, the identification module 5, and the second wireless module 16 can be located on the same circuit board.

[0035] Specifically, the inertial sensor can be an accelerometer or a gyroscope, etc. When the recognition module 5 is set on the stylus 3, the inertial sensor or camera module, in conjunction with the recognition module 5, can obtain the calculation information of the notes, which is then transmitted via the second controller 32 and the first wireless module 33. The second wireless module 16 receives the calculation information and transmits it to the first controller 13 for calculation, and finally displays the calculation result on the display screen 11. When the recognition module 5 is set on the calculator body 1, the inertial sensor or camera module collects the note trajectory written by the stylus 3 and transmits the collected note trajectory to the second wireless module 16 via the second controller 32 and the first wireless module 33. After receiving the note trajectory transmitted by the first wireless module 33, the second wireless module 16 transmits it to the recognition module 5. The recognition module 5 generates calculation information from the note trajectory and transmits it to the first controller 13 for calculation. The first controller 13 transmits the calculated result to the display screen 11 for display.

[0036] In this embodiment, the first wireless module 33 or the second wireless module 16 can also be connected to the cloud to upload the note trajectory to the cloud so that the user can use it with the mobile APP to record the note trajectory written on the handwriting tablet body 2.

[0037] In one embodiment, the recognition module 5 is disposed on the calculator body 1, and the handwriting tablet body 2 is provided with a handwriting layer 21 for use with the stylus 3 and a touch screen electrically connected to the calculator body 1 for recognizing handwriting traces. The touch screen is electrically connected to the recognition module 5, such as... Figure 7 As shown. Specifically, the touchscreen is the acquisition module 31, which can be a capacitive touchscreen or an electronic touchscreen. The handwriting layer 21 and the touchscreen are positioned above and below each other. When the user writes on the handwriting layer 21 with the stylus 3, the touchscreen senses the pressure and calculates the pressure position to record the note trajectory.

[0038] In this embodiment, the handwriting tablet body 2 or the calculator body 1 is provided with a wireless module that is electrically connected to the second controller 32 or the first controller 13. The wireless module can connect to the cloud to upload the note trajectory to the cloud so that the user can use it with a mobile APP to record the note trajectory written on the handwriting tablet body 2.

[0039] To facilitate the use of the stylus 3, a battery (not shown in the figure) is also provided on the stylus 3. The battery is electrically connected to the second controller 32, and the second controller 32 is powered by the battery, which eliminates the need for the stylus 3 to be connected to an external power source via a power cord. Specifically, the battery can be a button cell battery, a dry cell battery, or a rechargeable battery, etc.

[0040] In the above embodiments, the stylus 3 may not be stored on the calculator body 1 or the handwriting tablet body 2. Of course, in other embodiments, to facilitate the storage of the stylus 3, the calculator body 1 or the handwriting tablet body 2 is provided with a storage slot for storing the stylus 3, so that the stylus 3 can be stored in the storage slot when not in use.

[0041] In one embodiment, the handwriting tablet calculator further includes a connecting cable 4. A first wiring hole 15 is provided on the calculator body 1, and a second wiring hole 23 is provided on the handwriting tablet body 2. One end of the connecting cable 4 passes through the first wiring hole 15, is placed inside the calculator body 1, and is electrically connected to the recognition module 5. The other end of the connecting cable 4 passes through the second wiring hole 23, is placed inside the handwriting tablet body 2, and is electrically connected to the touchscreen. The connecting cable 4 enables the electrical connection between the recognition module 5 and the touchscreen, and the first wiring hole 15 and the second wiring hole 23 allow the two ends of the connecting cable 4 to be placed inside the calculator body 1 and the handwriting tablet body 2, respectively.

[0042] In one embodiment, the calculator body 1 and the handwriting tablet body 2 are rotatably connected so that when the calculator body 1 and the handwriting tablet body 2 are not in use, they can be folded and stored to reduce space occupation and facilitate the carrying and transportation of the handwriting tablet calculator of this embodiment.

[0043] In one embodiment, the calculator body 1 is provided with an adsorption assembly at a position away from the handwriting tablet body 2 and the support of the handwriting tablet body 2. The adsorption assembly includes a first magnetic member 22 and a second magnetic member 14 for cooperating with the first magnetic member 22. The first magnetic member 22 is adsorbed by the second magnetic member 14 when the calculator body 1 and the handwriting tablet body 2 are folded. By using the adsorption of the first magnetic member 22 and the second magnetic member 14, the calculator body 1 and the handwriting tablet body 2 can be adsorbed and fixed when folded, preventing the calculator body 1 and the handwriting tablet body 2 from separating, which would affect the carrying and transportation of the product.

[0044] Specifically, the first magnetic attachment 22 is disposed on the handwriting tablet body 2, and the second magnetic attachment 14 is disposed on the calculator body 1. Of course, in other embodiments, the second magnetic attachment 14 may also be disposed on the handwriting tablet body 2, and the first magnetic attachment 22 may be disposed on the calculator body 1, so that the calculator body 1 and the handwriting tablet body 2 can be attracted and fixed when folded.

[0045] In one embodiment, the first magnetic attractor 22 is a magnet, and the second magnetic attractor 14 is a material that can be attracted to the magnet, such as a magnet, an iron sheet, etc.

[0046] In other embodiments, the calculator body 1 and the handwriting tablet body 2 can also be connected by snaps or magnets, which can also achieve the connection between the calculator body 1 and the handwriting tablet body 2.

[0047] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0048] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the term "and / or" throughout the text includes three solutions; taking A and / or B as an example, it includes technical solution A, technical solution B, and a technical solution that simultaneously satisfies A and B. Furthermore, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them.
