At least two first pole metal elastic pieces 163 and two second pole metal elastic pieces 165 are arranged on the mounting frame 161 and are sequentially arranged at intervals along the central axis direction of the pen body 111. In one embodiment, the mounting frame 161 is semi-circular and is adapted to the inner wall of the pen body 111. The mounting frame 161 is disposed adjacent to the circuit board 13, and the mounting frame 161 and the circuit board 13 are disposed at an interval in a circumferential direction of an inner side wall of the pen body 111, and are located between the partition 113 and the circuit board 13 in a central axis direction of the pen body 111.

The at least two first pole metal elastic pieces 163 are electrically connected to the controller 14 in parallel. The at least one second pole metal dome 165 is directly electrically connected to the controller 14. A complete conductive path is formed between the at least two first pole metal dome 163 and the second pole metal dome 165 and the controller 14 through the conductive cylinder 31 (see fig. 7) of the pen core 30 and the corresponding conductive ring 35 disposed thereon. The controller 14 identifies the color of the pen core 30 according to the pen core color corresponding to the conducted first pole metal conductive sheet 163 when a conductive path is formed between at least one first pole metal elastic sheet 163 and the second pole metal elastic sheet 165 through the conductive ring 35 on the pen core 30 according to the corresponding relationship between the pre-stored combination of at least two first pole metal elastic sheets 163 and the pen core color.

Specifically, in one embodiment, the resistance value of each first pole metal spring 163 is different. Therefore, when the conductive ring 35 on the pen core 30 contacts different first pole metal domes 163, the current/voltage in the formed conductive path is different, and the controller 14 identifies the color of the pen core 30 according to the pre-stored correspondence between the current/voltage and the pen core color and the current/voltage in the conductive path.

Specifically, in another embodiment, each first pole metal dome 163 corresponds to an identification code, and the identification code is stored in the controller 14. The controller 14 identifies the color of the pen core 30 according to the pen core color corresponding to the identification code of the conductive positive electrode metal conductive sheet 163 when a conductive path is formed between at least one first electrode metal elastic sheet 163 and the second electrode metal elastic sheet 165 through the conductive ring 35 on the pen core 30 according to the correspondence between the identification code combination of at least two first electrode metal elastic sheets 163 and the pen core color.

Specifically, in an embodiment, referring to fig. 8 together, when the pen core 30a is inserted into the stylus pen 10 and any one of the first pole metal conducting strips 163 is not conducted, the controller 14 recognizes that the color of the pen core 30a is black. When the pen core 30b is inserted into the pen 10 and the first pole metal dome 163 located at the first position is turned on, the controller 14 recognizes that the color of the pen core 30b is yellow. When the pen core 30c is inserted into the pen 10 and the first pole metal dome 163 located at the second position is turned on, the controller 14 recognizes that the color of the pen core 30c is red. When the pen core 30d is inserted into the pen 10 and the first pole metal dome 163 located at the third position is turned on, the controller 14 recognizes that the color of the pen core 30d is purple. When the pen core 30e is inserted into the pen 10 and the first pole metal dome 163 at the second and third positions is turned on, the controller 14 recognizes that the color of the pen core 30e is green. When the pen core 30f is inserted into the pen 10 and the first pole metal elastic sheet 163 located at the first, second, and third positions is turned on, the controller 14 recognizes that the color of the pen core 30f is pink. When the pen core 30g is inserted into the pen 10 and the first pole metal elastic sheet 163 located at the first and third positions is turned on, the controller 14 recognizes that the color of the pen core 30g is brown. It should be noted that the above is only an example, and not a limitation, and the pen core may be specifically set according to actual needs, for example, the pen core color represented by the conduction of the first pole metal elastic sheet 163 located at the first position may also be red, and the like.

Specifically, in this embodiment, the number of the at least two first pole metal elastic sheets 163 is five. It is understood that, in other embodiments, the number of the at least two first pole metal elastic sheets 163 is not limited to five, and may be greater than or less than five, and may be specifically set according to actual needs.

Specifically, referring to fig. 5 again, the pressure sensing unit 17 is a pressure sensor. The pressure sensing unit 17 is electrically connected to the controller 14. The pen core 30 is accommodated in the second accommodation space 1113. The pressure-sensitive cell 17 is disposed between one end of the pen core 30 and the partition 113. In the present embodiment, the pressure-sensitive unit 17 is provided on the partition 113 at a position facing the tip end of the pen core 30. In another embodiment, the pressure-sensitive unit 17 is provided on the tip of the pen core 30. The other end of the pen core 30 penetrates out of the pen point 19. When the pen core 30 of the handwriting component 100 writes on the handwriting board 300 paved with the paper 310, the pressure sensing unit 17 senses a pressure value when the pen core 30 writes, converts the sensed pressure value into a voltage/current signal and transmits the voltage/current signal to the controller 14, and the controller 14 controls the communication unit 15 to transmit the voltage/current signal to the handwriting board 300 through the network 700. The tablet 300 forwards the voltage/current signal to the intelligent terminal 500. The intelligent terminal 500 responds to the voltage/current signal and displays the writing handwriting of which the thickness corresponds to the pressure value, and even if the user applies more force when writing with the stylus 100, the writing handwriting displayed on the intelligent terminal 500 is correspondingly thicker.

Specifically, the induction coil 18 is disposed inside the pen body 111 near one end of the pen tip 19 and surrounds the pen core 30, and is electrically connected to the controller 14. The stylus pen 10 writes on the paper 310 of the handwriting board 30 by electromagnetic induction or the like between the induction coil 18 and the handwriting board 30.

Each first pole conductive ring 351 corresponds to a first pole metal spring 163. The second pole conductive ring 353 is disposed corresponding to the second pole metal dome 165. When the pen core 30 is installed in the stylus pen 10, each first pole conductive ring 351 on the pen core 30 is in contact with one first pole metal elastic sheet 163 on the stylus pen 10, and the second pole conductive ring 353 on the pen core 30 is in contact with the second pole metal elastic sheet 165 on the stylus pen 10, so that a complete conductive path is formed among the first pole metal elastic sheet 163 on the stylus pen 10, the first pole conductive ring 351 on the pen core 30, the conductive barrel 31 of the pen core 30, the second pole conductive ring 353 of the pen core 30, the second pole metal elastic sheet 165 of the stylus pen 10, and the controller 14 of the stylus pen 10.

The controller 14 controls the communication unit 15 to send a writing color recognition signal including a color value to the tablet 300 through the network 700.

For example, referring to fig. 8, in an embodiment, the writing cores 30 of various colors are marked as follows, the writing cores 30a without the conductive rings 35 are black, the writing cores 30b with the first-position first-pole conductive rings 351 and the second-position second-pole conductive rings 353 represent yellow writing cores 30b, the writing cores 30c with the second-position first-pole conductive rings 351 and the second-position second-pole conductive rings 353 represent red writing cores 30c, the writing cores 30d with the third-position first-pole conductive rings 351 and the second-position second-pole conductive rings 353 represent purple writing cores 30d, the writing cores 30e with the second-position first-pole conductive rings 351 and the second-position second-pole conductive rings 353 represent green writing cores 30e, the writing cores 30f with the first-position first-pole conductive rings 351 and the second-position second-pole conductive rings 353353 represent brown writing cores 30 g. It will be appreciated that any color of pen core may be represented in terms of one or more of first pole conductive ring 351 and a second pole conductive ring 353.

It is understood that in other embodiments, the communication unit 39 may also be other chips with communication functions, for example, a WiFi chip. The controller 37 controls the electromagnetic induction board 33 to display corresponding writing in response to the writing input of the pen assembly 100 on the paper 310 on the writing board 32. The controller 37 controls the communication unit 39 to receive and recognize the writing color recognition signal and the writing trace of the handwriting pen assembly 100, and transmit the writing color signal including the color value and the writing trace to the intelligent terminal 500. It is understood that the writing script can also be stored in the controller 14 of the stylus assembly 100 having a memory function.

Referring to fig. 10, fig. 10 is a schematic block diagram of an intelligent terminal according to an embodiment of the present invention.

The intelligent terminal 500 receives the writing color signal and the writing trace through the communication unit 57, and displays the writing trace of the color corresponding to the color value on the display page according to the writing color signal and the writing trace. Specifically, the processor 51 of the intelligent terminal 500 responds to the writing color recognition signal, runs the handwriting board application program, starts the embedded color calling program, and converts the corresponding writing handwriting on the display page corresponding to the handwriting board application program into the writing handwriting having the color value.

Please refer to fig. 11, which is a flowchart illustrating a writing color synchronization method according to an embodiment of the present application. The writing color synchronization method is used to synchronize the writing color of the handwriting pen assembly 100 when writing on the handwriting pad 300 with the writing color displayed on the intelligent terminal 500. The writing color synchronization method is applied to the writing color synchronization system 1000 described above, and the execution sequence is not limited to the sequence shown in fig. 11. The method comprises the following steps:

step 1110, after the cartridge 30 is loaded into the stylus 10, the power supply and the wireless connection of the stylus 10 are started, and the power supply and the wireless connection of the tablet 300 are simultaneously started. Specifically, after the cartridge 30 is loaded into the stylus pen 10, the power supply unit 12 of the stylus pen 10 is activated to supply power to the stylus pen 10, and the communication unit 15 is activated, and at the same time, the power supply of the tablet 300 is activated, and the communication unit 39 is activated.

In step 1120, the communication unit 15 of the stylus 10 is connected to the communication unit 39 of the tablet 300.

In step 1130, the writing pen 10 recognizes the color of the pen core 30 inserted therein through the color recognition component 16 inside the pen body and generates a writing color recognition signal having a color value, and outputs the writing color recognition signal to the tablet 300.

Specifically, the color recognition component 16 includes at least two first pole metal dome sheets 163 and one second pole metal dome sheet 165. At least two first pole metal elastic pieces 163 and two second pole metal elastic pieces 165 are respectively disposed on the inner side wall of the pen body 111 and are respectively electrically connected with the controller 14. In this embodiment, the first pole metal dome 163 is a positive pole metal dome, and the second pole metal dome 165 is a negative pole metal dome. The at least two first pole metal elastic pieces 163 are electrically connected to the controller 14 in parallel. The at least one second pole metal dome 165 is directly electrically connected to the controller 14. A complete conductive path is formed between the at least two first pole metal dome 163 and the second pole metal dome 165 and the controller 14 through the conductive cylinder 31 (see fig. 7) of the pen core 30 and the corresponding conductive ring 35 disposed thereon. The controller 14 identifies the color of the pen core 30 according to the pen core color corresponding to the combination of the conductive first plates 163 when a conductive path is formed between at least one first plate 163 and the second plate 165 through the conductive ring 35 on the pen core 30 according to the correspondence between the pre-stored combination of at least two first plate 163 and the pen core color.

Specifically, in one embodiment, the resistance value of each first pole metal spring 163 is different. Therefore, when the conductive ring 35 on the pen core 30 contacts the different first pole metal dome 163, the current/voltage in the formed conductive path is different, the controller 14 recognizes the color of the pen core 30 according to the pre-stored correspondence between the magnitude of the current/voltage and the color of the pen core, and the magnitude of the current/voltage in the conductive path, generates a writing color recognition signal having a color value, and outputs the writing color recognition signal to the writing pad 300.

Specifically, in another embodiment, each first pole metal dome 163 corresponds to an identification code, and the identification code is stored in the controller 14. The controller 14 recognizes the color of the pen core 30 according to the pen core color corresponding to the recognition code of the conductive positive electrode metal conductive sheet 163, generates a writing color recognition signal having a color value, and outputs the writing color recognition signal to the handwriting board 300, when a conductive path is formed between at least one first electrode metal spring 163 and the second electrode metal spring 165 through the conductive ring 35 on the pen core 30 according to the correspondence between the pre-stored combination of the recognition codes of at least two first electrode metal springs 163 and the pen core color.
