The control module can calculate the rotation angle of the second rotating member 122 relative to the base 110. Thus, the control system identifies the rotation angles of the first rotating member 121 and the second rotating member 122 in a magnetic induction manner, thereby judging the alignment situation of the first identifier 151 and the second identifier 152. The prompting component can prompt the user about the meaning or pronunciation after the alignment of the first identifier and the second identifier. The magnetic induction method has advantages such as non-contact and continuously distinguishable angles, which can improve the use reliability and convenience of the learning tool 100, is conducive to maintaining the user's learning interest, and is conducive to expanding the scope of application.

[0065] The base 110 can be composed of multiple parts and serves as the installation foundation for the components of the learning tool 100.

[0067] See Figure , in other examples, the second rotating member 122 can be annular and provided on the radial outer side of the first rotating member 121, and the first identifier 151 and the second identifier 152 can be respectively provided on the end faces of the first rotating member 121 and the second rotating member 122; the first rotating member 121 can be solid or annular. The structural shapes and relative positional relationships of the first rotating member 121 and the second rotating member 122 can be adapted according to different usage scenarios.

[0068] The number of the first identifier 151 and the second identifier 152 can be adapted according to different usage scenarios. In some examples, the number of the first identifier 151 and the second identifier 152 can both be one, and the control system of the learning utensil 100 can determine whether the first identifier 151 and the second identifier 152 are aligned and / or the interval size between the two. In other examples, the number of both the first identifier 151 and the second identifier 152 is multiple, the multiple first identifiers 151 are distributed around the rotation axis of the first rotating member 121, the multiple second identifiers 152 are distributed around the rotation axis of the second rotating member 122, and any one of the first identifiers 151 and any one of the second identifiers 152 can be aligned with each other. In some examples, the base 110 can also be provided with a reference identifier, and the control system of the learning utensil 100 can determine the alignment situation among the first identifier 151, the second identifier 152 and the reference identifier.

[0069] According to different usage scenarios, the first identifier 151 and the second identifier 152 can be selected from any one or more of characters, strokes, numbers, operators, letters, phonetic symbols, tones and patterns.

[0070] The power for driving the first rotating member 121 and the second rotating member 122 to rotate can be manually applied by the user or provided by a driver (such as a motor, a cylinder).

[0071] Both the first magnet 131 and the second magnet 132 are used to generate a magnetic field. In some examples, both can be permanent magnets, such as magnets.

The second magnetic induction element 142 can calculate the rotation angle of the second rotating member 122 by detecting the change in the magnetic field angle of the second magnet 132, so as to know the alignment situation of the first identifier 151 and the second identifier 152.

[0072] The first magnetic induction element 141 and the second magnetic induction element 142 detect the change in the magnetic field angle in a magnetic induction manner.

[0073] The magnetization directions of the first magnet 131 and the second magnet 132 are both perpendicular to the rotation axis. Thus, the magnetic field lines of the magnetic fields generated by the first magnet 131 and the second magnet 132 at the position of the magnetic induction element can also be substantially perpendicular to the rotation axis (see ​ ), so as to facilitate the detection of the magnetic field angle by the first magnetic induction element 141 and the second magnetic induction element 142.

See ​ , in some examples, the first magnetic induction element 141 is provided on one side of the first magnet 131 along the rotation axis direction, and this setting method can be called "on-axis".

Refer to ​ or ​ , in other examples, the first toroidal surface and the second toroidal surface may be respectively located on the axial end faces of the first rotating member 221 and the second rotating member 222.

[0076] The learning utensil 100 may include a plurality of rotating members, and the rotating members, magnets, and magnetic induction elements may be configured in one-to-one correspondence. The number of rotating members may be adjusted according to different usage scenarios.

[0077] The prompting component is used to generate visual, auditory, or kinesthetic prompting signals. The prompting component may be presented as a display screen, a speaker, or a kinesthetic device containing a vibration motor.

[0078] The control module controls the operation of the prompting component according to the feedback signals of the first magnetic induction element 141 and the second magnetic induction element 142. The control module may include a processor and has functions of signal processing, digital operation, and issuing control instructions. In some examples, the magnetic induction element and the control module may be provided on the same circuit board.

[0080] The first rotating member 321, the second rotating member 322, and the third rotating member 323 are coaxially arranged. The second rotating member 322 can be annular and disposed radially outside the first rotating member 321, and the third rotating member 323 can be annular and disposed radially outside the second rotating member 322. The first rotating member 321 is located radially inside the second rotating member 322 and can also be annular.

The first rotating member 321 is provided with a first identifier 351, the second rotating member 322 is provided with a second identifier 352, and the third rotating member 323 is provided with a third identifier 353. Further, the first rotating member 321 has a first toroidal surface, the first identifier 351 is disposed on the first toroidal surface, the second rotating member 322 has a second toroidal surface, the second identifier 352 is disposed on the second toroidal surface, the third rotating member 323 has a third toroidal surface, the third identifier 353 is disposed on the third toroidal surface, and the first toroidal surface, the second toroidal surface, and the third toroidal surface are flush with each other.

Any one of the first identifiers 351 and any one of the second identifiers 352 can be aligned with each other, and any one of the third identifiers 353 and any one of the second identifiers 352 can be aligned with each other.

[0081] See ​ , a specific description of the transmission assembly will be given. The transmission assembly is used to transmit the power of the rotating member to the magnet. The first rotating member 321 and the first magnet 331 are respectively connected to the transmission assembly, and the first rotating member 321 drives the first magnet 331 to rotate through the transmission assembly; the second rotating member 322 and the second magnet are respectively connected to the transmission assembly, and the second rotating member 322 drives the second magnet to rotate through the transmission assembly; the third rotating member 323 and the third magnet are respectively connected to the transmission assembly, and the third rotating member 323 drives the third magnet to rotate through the transmission assembly. The rotating member drives the magnet to rotate through the transmission assembly. Thus, the structural shapes of the first rotating member 321, the second rotating member 322, and the third rotating member 323 can be adapted according to specific application scenarios.

[0082] In some examples, the transmission assembly includes a driving wheel and a driven wheel, and the driving wheel and the driven wheel cooperate with each other to transmit power; the driving wheel is connected to the first rotating member 321, and the driven wheel is connected to the first magnet 331, or the driving wheel is connected to the second rotating member 322, and the driven wheel is connected to the second magnet, or the driving wheel is connected to the third rotating member 323, and the driven wheel is connected to the third magnet. The transmission assembly can be selected from any one of a gear transmission mechanism, a belt transmission mechanism, a chain transmission mechanism, a Geneva drive mechanism, and a link transmission mechanism. The driving wheel and the driven wheel can be presented as gears, pulleys, or sprockets.

[0083] Preferably, the transmission ratio formed by the driving wheel and the driven wheel is 1:1. Thus, the rotating member and the magnet can rotate synchronously at a ratio of 1:1, and the angle of the magnet detected by the magnetic induction element can be used as the angle of the rotating member. In this case, when the learning utensil 300 is restarted after power-off, the control system can determine the real-time angle of the rotating member according to the real-time angle of the magnet detected by the magnetic induction element, so as to know the alignment situation of each identifier, thereby improving the intelligence level and the convenience of use of the learning utensil 300. In some examples, the transmission ratio formed by the driving wheel and the driven wheel is other ratios. The learning utensil 300 can be provided with a register, and the register can record the angle of the rotating member when power is off. After restart, the control system calculates the real-time angle of the rotating member according to the transmission ratio and the information recorded in the register, so as to know the alignment situation of each identifier; it is also possible not to require a register, but after power-off and restart, the user restores each rotating member to the origin and re-calibrates the angle.

[0084] In some examples, the transmission assembly can also transmit power by magnetic force. Specifically, the transmission assembly can include a driving magnet and a driven magnet. The driving magnet is connected to the rotating member, and the driven magnet is connected to the magnet. The driving magnet rotates with the rotating member and drives the driven magnet to rotate through attraction or repulsion, thereby driving the magnet to rotate.

[0085] The learning utensil 300 can include three transmission assemblies, namely a first transmission assembly 361, a second transmission assembly 362, and a third transmission assembly 363. The first transmission assembly 361, the second transmission assembly 362, and the third transmission assembly 363 respectively correspond to a first rotating member 321, a second rotating member 322, and a third rotating member 323. The first transmission assembly 361 includes a first driving wheel 3611 and a first driven wheel 3612. The second transmission assembly 362 includes a second driving wheel 3621 and a second driven wheel 3622. The third transmission assembly 363 includes a third driving wheel 3631 and a third driven wheel 3632. The three transmission assemblies can work independently of each other.

[0086] In some examples, the first rotating member 321 has a first shaft portion, the first shaft portion is rotatably mounted on the base 310, the first driving wheel 3611 is fixedly connected to the first shaft portion, the second rotating member 322 has a second shaft portion, the second shaft portion is in a sleeve shape and is rotatably sleeved on the outer side of the first shaft portion, and the second driving wheel 3621 is fixedly connected to the second shaft portion. The first shaft portion is rotatably connected to the base 310; the first shaft portion may be in a sleeve shape, and the base 310 is provided with a positioning shaft 3122 that cooperates with the first shaft portion; alternatively, the first shaft portion may be solid, and the base 310 is provided with a hole-shaped structure or a groove-shaped structure that cooperates with the first shaft portion. Thus, the first shaft portion can transmit the rotational power of the first rotating member 321 to the first driving wheel 3611, and the second shaft portion can transmit the rotational power of the second rotating member 322 to the second driving wheel 3621. With this structure, the learning utensil 300 can be provided with multiple rotating members, the rotating members are arranged in sequence from the inside to the outside, and the corresponding driving wheels are arranged along the axial direction. Thus, the applicable range of the learning utensil 300 can be expanded. In addition, with this structure, the distance between each magnet can be adjusted as needed, that is, there can be a relatively large distance between each magnet to avoid the magnetic field interference of any one magnet from interfering with the operation of the magnetic induction element corresponding to another magnet, thereby improving the working reliability of the learning utensil 300.

[0087] In some examples, the base 310 is provided with a positioning shaft 3122 coaxial with the first rotating member 321, the first rotating member 321 has a first sleeve portion 3211, the first sleeve portion 3211 is rotatably sleeved on the positioning shaft 3122, the first driving wheel 3611 is fixedly connected to the first sleeve portion 3211, the second rotating member 322 has a second sleeve portion 3221, the second sleeve portion 3221 is rotatably sleeved on the outer side of the first sleeve portion 3211, and the second driving wheel 3621 is fixedly connected to the second sleeve portion 3221. The first driving wheel 3611 and the second driving wheel 3621 can be arranged along the axial direction. Thus, the first sleeve portion 3211 can transmit the rotational power of the first rotating member 321 to the first driving wheel 3611, and the second sleeve portion 3221 can transmit the rotational power of the second rotating member 322 to the second driving wheel 3621. With this structure, the learning utensil 300 can be provided with multiple rotating members, the rotating members are arranged in sequence from the inside to the outside, and the corresponding driving wheels are arranged along the axial direction. Thus, the applicable range of the learning utensil 300 can be expanded.

[0088] See ​ and ​, taking three rotating members as an example, the first rotating member 321, the second rotating member 322, and the third rotating member 323 are all provided with a turntable portion and a sleeve portion. The sleeve portion extends from the turntable portion along the cylinder axis direction. The sleeve portion of the second rotating member 322 is rotatably sleeved on the outside of the sleeve portion of the first rotating member 321, and the sleeve portion of the third rotating member 323 is rotatably sleeved on the outside of the sleeve portion of the second rotating member 322; the turntable portions of the first rotating member 321, the second rotating member 322, and the third rotating member 323 are arranged in sequence along the cylinder axis direction. The turntable portion of the second rotating member 322 forms a clamping force on the turntable portion of the third rotating member 323, and the turntable portion of the first rotating member 321 forms a clamping force on the turntable portion of the second rotating member 322. From the perspective of the user, the cylinder axis direction can be the vertically downward direction. During assembly, the third rotating member 323, the second rotating member 322, and the first rotating member 321 are placed from top to bottom in sequence. The second rotating member 322 restricts the axial position of the third rotating member 323, and the first rotating member 321 restricts the axial position of the second rotating member 322. Thus, the assembly efficiency of the learning utensil 300 can be improved. Each identifier can be provided on the upper surface of the corresponding turntable portion.

[0089] In some examples, the base 310 includes a base 311 and a central mounting member 312. The central mounting member 312 is provided with a pressure plate portion 3121 and a positioning shaft 3122. The positioning shaft 3122 is detachably connected to the base 311. The first rotating member 321 has a first sleeve portion 3211. The first sleeve portion 3211 is rotatably sleeved on the positioning shaft 3122. The second rotating member 322 has a second sleeve portion 3221. The second sleeve portion 3221 is rotatably sleeved on the outside of the first sleeve portion 3211. The pressure plate portion 3121 and the base 311 respectively form axial constraints on the first rotating member 321 and the second rotating member 322 from both ends of the axis. Thus, the pressure plate portion 3121 of the base 311 and the central mounting member 312 can achieve axial limit for each rotating member. This structure is also applicable to the case where the number of rotating members is three or more.

[0090] See ​ , the driven wheel is provided with a shaft body. The shaft body is rotatably mounted on the base 310. The first magnet 331 or the second magnet is mounted at the end of the shaft body. Mounting the magnet at the end of the shaft body can facilitate the arrangement of the corresponding magnetic induction element. According to the specific structural form, the magnetic induction element can be arranged in an on-axis or off-axis manner to simplify the structure and improve the detection accuracy.

[0091] In some examples, the rotation axes of the first rotating member 321, the first magnet 331, and the second magnet are parallel to each other. The rotation axes of each rotating member and each magnet can all be arranged along the cylinder axis direction, whereby the unified arrangement of each magnetic induction element can be facilitated. The first magnetic induction element 341 and the second magnetic induction element 342 are arranged on the same circuit board. Each magnetic induction element can be arranged on the same circuit board, whereby the signal transmission performance can be improved and the cost can be reduced. The circuit board can be laid on the bottom of the cavity of the base 310.

[0092] See ​ , in some other examples, the rotation axis of the magnet can also be set horizontally. The lower end surface of the first rotating member 411 is provided with transmission teeth, which mesh with the first driven wheel 412, so as to drive the first driven wheel 412 and the first magnet 131 to rotate. The lower end surface of the second rotating member 421 is also provided with transmission teeth, which mesh with the second driven wheel 422, so as to drive the second driven wheel 422 and the second magnet 132 to rotate.

[0093] The elastic member 371 is installed on the base 310. The driving wheel and the driven wheel are both gears. The elastic member 371 is inserted into the gap between adjacent teeth of the driving wheel or the driven wheel. When the driving wheel or the driven wheel rotates, it toggles the elastic member 371. When the driving wheel or the driven wheel rotates and toggles the elastic member 371, a toggling sound similar to "click" can be generated, improving the user's hand feeling. In addition, the elastic member 371 can also provide rotational damping to the driving wheel or the driven wheel, improving the position stability of the rotating member. Each rotating member can be configured with an elastic member 371. The elastic member 371 can be made of metal and can be in the shape of an elastic rod or an elastic sheet.

[0094] The display module 372 is arranged inside the trajectory circle formed by the rotation of the first identifier 351. The display module 372 is used to display content related to the information formed by the alignment of the first identifier 351 and the second identifier 352. In some examples, the first rotating member 321 can be in a ring shape, the first identifier 351 is arranged on the ring, and the display module 372 is arranged inside the ring. In some other examples, the first rotating member 321 can be solid, and the display module 372 is arranged on the first rotating member 321 and is inside the trajectory circle formed by the rotation of the first identifier 351. The display module 372 is used to display content related to the information formed by the alignment of each identifier. In some examples, for the case where the number of rotating members is two, the first identifier 351 can be an exponent (number), the second identifier 352 can be a base (number), and the display module 372 can display the formula of exponential operation and its operation result. The learning utensil 300 can also be provided with a speaker for voice prompting content related to the information formed by the alignment of the first identifier 351 and the second identifier 352, such as the result of exponential operation. The display module 372 can be a display screen.

[0095] The inspection aid 380 is connected to the base 310. The inspection aid 380 is located on the side closer to the user of the first identifier 351 and the second identifier 352. The inspection aid 380 is provided with an inspection window 381. The first identifier 351 and the second identifier 352 in the aligned state are both located within the inspection window 381. The inspection aid 380 can assist or prompt the user to view the identifiers in the aligned state. When in use, the user rotates each rotating member according to requirements so that the target identifier is located within the observation window. The control system can identify the identifier located within the observation window by detecting the rotation angles of the respective rotating members. The display module 372 can display content related to the information formed by aligning with the identifier.

[0096] In some examples, both the first rotating member 321 and the second rotating member 322 are made of non-light-transmitting materials. The shape area or contour of the first identifier 351 and the second identifier 352 is light-transmitting. The first indicator light 391 is provided on the side of the first rotating member 321 away from the user and is used to light up the first identifier 351. The second indicator light 392 is provided on the side of the second rotating member 322 away from the user and is used to light up the second identifier 352. The target identifier moves above the indicator light, and the indicator light emits light and lights up the target identifier, thereby prompting and assisting the user to view. The number of rotating members and indicator lights are configured in one-to-one correspondence, and can be three or more. The inspection aid 380 and the indicator lights can be configured simultaneously or set separately. In some examples, the material of the rotating member is non-light-transmitting plastic, and the material of the identifier is transparent plastic. The identifier can be formed on the rotating member by secondary injection molding.

[0097] See ​ , the present application also provides another learning utensil 500. The learning utensil 500 and the learning utensil 300 can have the same structure and device configuration. The main difference between the two is that the learning utensil 500 uses different identifiers. The first identifier 551, the second identifier 552, and the third identifier 553 of the learning utensil 500 can be adapted according to different usage scenarios. For example, they can be numbers, letters, or other characters, and can also be patterns.

[0098] See ​ and ​, the present application also provides another learning utensil 600.

The rotating members, transmission components, magnets, and magnetic induction elements are configured in one-to-one correspondence, and each transmission component includes a driving wheel and a driven wheel that cooperate with each other. In some examples, the driving wheel of the transmission component of the learning utensil 600 is an internal gear 650, and the driven wheel is an external gear 661 that meshes with the internal gear 650. The rotating member drives the magnet to rotate through the meshing of the internal gear 650 and the external gear 661, so that the rotating member does not have to be provided with a sleeve portion, thereby simplifying the structure of the rotating member.

[0099] In some examples, the learning utensil provided by the present application can be used as an assistant teaching utensil, for example, for assisting students in learning arithmetic. The first identifier and the third identifier can be numbers, and the second identifier can be an arithmetic operator (addition, subtraction, multiplication, division).

[0100] The present application also provides an entertainment utensil, which has the same or similar structure as any of the above learning utensils. The identifier of the entertainment utensil is different from that of the learning utensil. In some examples, the first identifier of the entertainment utensil can be a plant pattern (the food of an animal), and the second identifier can be an animal pattern. When the plant pattern and the animal pattern are correctly corresponded, the prompting component can emit a corresponding sound. In some examples, the entertainment utensil can also be set on a table as an appliance for playing tabletop games.

[0101] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
