Description

Technical Field

[0001] This application relates to the field of stationery, and in particular to an electronic pen. Background Art

[0002] Writing pens are devices that people use for writing, drawing, or making marks, and are roughly divided into signature pens, highlighters, gel pens, and marker pens, etc., which are widely used in people's production and life.

[0003] Writing pens in the related art usually include a pen tube, a pen tip, and a refill. One end of the refill is located inside the pen tube, and the other end extends outside the pen tip. The refill usually includes an ink tube and a writing head inserted into the ink tube. A limiting ring is integrally formed on the writing head, and the limiting ring abuts against the ink tube to quickly determine the assembly position of the writing head and the ink tube.

[0004] In view of the above related art, some schools or educational institutions usually need to measure the writing volume of students daily or during a certain period of time in order to formulate teaching tasks or control the amount of students' homework. However, during the writing process of the writing pens in the related art, it is difficult to measure the daily writing volume of students, which is not convenient for educational institutions to formulate teaching tasks or control the amount of students' homework, and thus needs to be improved. Summary of the Invention

[0005] In order to facilitate the measurement of the daily writing volume of students, this application provides an electronic pen.

[0006] The electronic pen provided by this application adopts the following technical solutions:

[0007] An electronic pen includes a pen tip, a pen tube, and a refill, and further includes: a circuit board fixed inside the pen tube; two contacts respectively connected to the circuit board; a trigger part disposed inside the pen tube, when the writing head of the refill is squeezed and the refill moves, the trigger part can be conducted with the two contacts; a reset part having elasticity and disposed inside the pen tube, and can reset the refill and open the trigger part from the two contacts.

[0008] By adopting the above technical solutions, when a student starts writing, the writing head of the refill is squeezed and the refill moves, and then the trigger part is conducted with the two contacts, so that the circuit board is conducted. When the student lifts the pen, the reset part resets the refill and opens the trigger part from the two contacts, so that the circuit board is opened. Repeating this way, by using the movement of the refill to control the conduction or opening of the trigger part with the two contacts, the conduction and opening of the circuit board are realized. According to how many strokes or how many words the student writes when the circuit board is conducted once, and then by recording the number of times the circuit board is conducted, the writing volume of the student can be estimated, which is convenient for educational institutions to formulate teaching tasks or control the amount of students' homework.

[0009] Meanwhile, if the circuit board is connected to a counter or a timer, parents or educational institutions can estimate the daily learning duration and the amount of learning tasks of students by observing the display of the counter or the timer, which is convenient for parents or educational institutions to control the daily learning tasks of students, thereby improving the practicality. At the same time, this design enables students to estimate the amount of ink in the refill by observing the display of the counter or the timer, so as to facilitate the timely replacement of the refill by students, and further improve the usability of the electronic pen.

[0010] Optionally, the triggering part includes: a conductive block, which is movably arranged in the pen tube and located between the refill and the circuit board; wherein, the ink tube of the refill can push the conductive block to move and make the conductive block contact with the two contact heads, and the reset part can separate the conductive block from the two contact heads.

[0011] By adopting the above technical solution, when a student starts writing, the writing head of the refill is squeezed and the refill moves, then the refill pushes the conductive block to move towards the circuit board. When the conductive block contacts the two contact heads, the circuit board is turned on. When the student lifts the pen, the reset part makes the conductive block drive the refill to reset and separates the conductive block from the two contact heads, so that the circuit board is turned off. By setting a triggering part with a simple structure and convenient operation, the rapid control of the circuit board being turned on or off is realized, thereby improving the use stability of the electronic pen.

[0012] Optionally, the triggering part includes: a conductive block, which is movably arranged in the pen tube and can contact the two contact heads; a trigger tube, which is movably arranged in the pen tube and is made of plastic or metal material. One end of the trigger tube abuts against the limit ring of the refill, and the other end is connected to the conductive block; wherein, the reset part can separate the conductive block from the two contact heads.

[0013] By adopting the above technical solution, when a student starts writing, the writing head of the refill is squeezed and the refill moves, then the limit ring of the refill pushes the trigger tube to drive the conductive block to move towards the circuit board. When the conductive block contacts the two contact heads, the circuit board is turned on. When the student lifts the pen, the reset part drives the conductive block to drive the trigger tube and the refill to reset, and separates the conductive block from the two contact heads, so that the circuit board is turned off.

[0014] During the production and processing of the ink tube of the refill, due to reasons such as processing equipment or processing difficulty, it is very difficult to control the length of the ink tube. If the ink tube is used to drive the conductive block to move, when the ink tube is too long or too short, problems such as the conductive block always contacting the contact head or being unable to contact the contact head are likely to occur, thus there is a risk that the circuit board is always turned on or unable to be turned on.

[0015] In this design, by using the limiting ring of the refill to push the trigger tube to drive the conductive block to move, since the limiting ring of the refill is integrally formed with the writing tip of the refill, the processing accuracy of the limiting ring is relatively high. At the same time, the trigger tube is made of plastic or metal materials, and plastic can be injection molded and metal can be turned, so that the processing length of the trigger tube is relatively accurate. Therefore, this design can effectively reduce the risk that the circuit board is always conducting or cannot conduct, which can not only improve the measurement accuracy but also improve the use stability of the electronic pen.

[0016] Optionally, the triggering part includes: a trigger tube, movably arranged in the pen tube and one end of which abuts against the limiting ring of the refill; a support cap, rotatably sleeved on the trigger tube; at least two conductive columns, respectively conductively connected to the corresponding contacts; at least one conductive rod, fixed on the support cap and both ends of which can contact the corresponding conductive columns and conduct the two contacts; wherein, a driving mechanism capable of driving the support cap to rotate is arranged in the pen tube, and the resetting member can drive the support cap and the refill to reset.

[0017] By adopting the above technical solution, when the student starts writing, the writing tip of the refill is squeezed and the refill moves, and then the limiting ring of the refill pushes the trigger tube to drive the support cap to move towards the circuit board. At the same time, the driving mechanism drives the support cap to drive the conductive rod to rotate. When both ends of the conductive rod respectively contact the corresponding conductive columns, the circuit board is conducted. When the student lifts the pen, the resetting member makes the support cap and the refill move away from the circuit board and reset. At the same time, the driving mechanism drives the support cap to drive the conductive rod to rotate. When both ends of the conductive rod respectively separate from the corresponding conductive columns, the circuit board is open. By using the driving mechanism to drive the support cap to drive the conductive rod to rotate, and through the conduction or disconnection of the conductive rod and the conductive column, the fast and stable control of the conduction or disconnection of the circuit board is realized, so as to facilitate the fast and accurate recording of the conduction times of the circuit board, and further improve the use stability of the electronic pen.

[0018] Optionally, the driving mechanism includes: a support frame, fixed in the pen tube; at least one control member, each control member includes a driving block and a reset block, the driving block and the reset block are respectively fixed on the support frame, and the support cap is located between the driving block and the corresponding reset block; a driving tooth part, fixed on the outer wall of the support cap close to the driving block; a reset tooth part, fixed on the outer wall of the support cap close to the reset block; wherein, when the support cap moves towards the circuit board, the side wall of the driving tooth part and the driving block make the support cap rotate, and when the support cap moves away from the circuit board, the side wall of the reset tooth part and the reset block make the support cap.

[0019] By adopting the above technical solution, when the student starts writing, the writing head of the refill is squeezed and the refill moves. Then, the limiting ring of the refill pushes the trigger tube to drive the support cap to move towards the circuit board. At the same time, the support cap drives the conductive rod to rotate under the combined action of the side wall of the driving tooth part and the corresponding driving block. When the two ends of the conductive rod contact the corresponding conductive posts respectively and make the two contacts conduct, the circuit board conducts. When the student lifts the pen, the reset member makes the support cap and the refill move away from the circuit board and reset. At the same time, the support cap drives the conductive rod to rotate under the combined action of the side wall of the reset tooth part and the corresponding reset block. When the two ends of the conductive rod separate from the corresponding conductive posts respectively, the circuit board opens. By setting a driving mechanism with a simple structure and convenient operation, the rapid and stable rotation of the support cap is realized, so as to realize the stable control of the conduction and opening of the circuit board, and further improve the measurement accuracy.

[0020] Optionally, the driving tooth part includes: at least one driving wheel tooth, one side wall of the driving wheel tooth is a driving inclined surface, and the other side wall is a limiting inclined surface; the reset tooth part includes: at least one reset wheel tooth, one side of the reset wheel tooth is a forward rotation inclined surface, and the other side is a reverse rotation inclined surface, and the inclination directions and inclination angles of the driving inclined surface and the reverse rotation inclined surface are the same; wherein, when the support cap moves towards the circuit board, the driving inclined surface and the driving block make the support cap rotate forward, and when the support cap moves away from the circuit board, the reverse rotation inclined surface and the reset block make the support cap rotate backward.

[0021] By adopting the above technical solution, when the student starts writing and makes the refill drive the trigger tube and the support cap to move towards the circuit board, the support cap drives the conductive rod to rotate forward under the action of the driving inclined surface and the corresponding driving block, and makes the circuit board conduct. When the student lifts the pen, the reset member makes the support cap drive the refill and the trigger tube to move away from the circuit board and reset. At the same time, the support cap drives the conductive rod to rotate backward and reset under the action of the reverse rotation inclined surface and the corresponding reset block, so that the circuit board opens.

[0022] By setting a driving mechanism with a simple structure, convenient operation and stable driving effect, the stable reciprocating rotation of the support cap and the conductive rod is realized, so as to realize the rapid and stable control of the conduction or disconnection of the circuit board, and further improve the use stability of the electronic pen. At the same time, this design enables the support cap to rotate automatically and reciprocally when moving towards or away from the circuit board, which can not only save the driving source of the support cap, but also improve the linkage between components and the resource utilization efficiency.

[0023] Optionally, the driving tooth portion includes at least two driving wheel teeth, one side wall of the driving wheel teeth being a driving inclined surface and the other side wall being a limiting inclined surface; the reset tooth portion includes at least two reset wheel teeth, one side of the reset wheel teeth being a forward rotation inclined surface and the other side being a reverse rotation inclined surface, and the inclination direction of the forward rotation inclined surface being opposite to that of the driving inclined surface; wherein, when the support cap moves towards the circuit board, the driving inclined surface and the driving block cause the support cap to rotate forward, and when the support cap moves away from the circuit board, the forward rotation inclined surface and the reset block cause the support cap to continue to rotate forward.

[0024] By adopting the above technical solution, when the student starts writing and the pen tip drives the trigger tube and the support cap to move towards the circuit board, the support cap drives the conductive rod to rotate forward under the action of the driving inclined surface and the corresponding driving block. When the student lifts the pen, the reset member causes the support cap to drive the pen tip and the trigger tube to move away from the circuit board and reset. At the same time, the support cap drives the conductive rod to continue to rotate under the action of the forward rotation inclined surface and the corresponding reset block, and makes the support cap abut against the next driving inclined surface.

[0025] By providing a driving mechanism with a simple structure, convenient operation and stable driving effect, the stable unidirectional rotation of the support cap and the conductive rod is realized, so as to realize the fast and stable control of the conduction or disconnection of the circuit board, thereby further improving the use stability of the electronic pen. At the same time, this design enables the support cap to rotate automatically and reciprocally when moving towards or away from the circuit board, which can not only save the driving source of the support cap, but also improve the linkage between components and the resource utilization efficiency.

[0026] Optionally, the end of the conductive rod penetrates through the corresponding driving wheel teeth and is located at the middle position of the corresponding driving inclined surface.

[0027] By adopting the above technical solution, when the electronic pen is in an idle state, the support cap and other components are reset, and the conductive column is located at one side position of the driving inclined surface. When the electronic pen is inserted into the pen cap and in a storage state, the support cap and other components move towards the circuit board, and the support cap rotates, and the conductive column is located at the other side position of the corresponding driving inclined surface.

[0028] If the ends of the conductive rod are located on both sides of the corresponding driving slope, when the electronic pen is in the storage state or idle state, there is a risk that the ends of the conductive rod will be connected to the corresponding conductive column, thereby affecting the measurement accuracy. The ends of the conductive rod in this design are located in the middle of the driving slope, so that the support cap needs to move a certain distance toward the conductive column and the support cap needs to be rotated a certain angle before the conductive rod can contact the corresponding conductive column. This design can avoid the problem of conduction between the conductive rod and the corresponding conductive column as much as possible, whether the electronic pen is in the storage state or the idle state, thereby improving the measurement accuracy and further improving the stability of the electronic pen.

[0029] Optionally, it also includes: a blocking cover, which is arranged at one end of the pen tube away from the pen tip; and a power supply, which is arranged in the blocking cover and electrically connected to the circuit board.

[0030] By adopting the above technical solution and setting a power supply to realize stable power supply to the circuit board, it is convenient for students to use and the convenience of using the electronic pen can be improved.

[0031] Optionally, it also includes: a USB plug, which is arranged on the blocking cover and is electrically connected to the power supply.

[0032] By adopting the above technical solution and providing a USB plug, the rechargeable capability of the power supply is achieved, thereby further improving the convenience of using the electronic pen.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] By utilizing the movement of the pen core to control the trigger part to be connected or open with the two contacts, when the student starts to write, the writing head of the pen core is squeezed and the trigger part is connected with the two contacts, thereby connecting the circuit board; when the student lifts the pen, the reset member resets the pen core and opens the trigger part with the two contacts, thereby opening the circuit board, and so on. By recording the number of times the circuit board is connected, the student's writing volume can be estimated, so that it is convenient for educational institutions to formulate teaching tasks or control the amount of students' homework;

[0035] By setting a trigger part with a simple structure and convenient operation, the circuit board can be quickly controlled to be turned on or off, thereby realizing a quick and accurate record of the number of times the circuit board is turned on, thereby improving the use stability of the electronic pen;

[0036] By setting up a driving mechanism with simple structure, convenient operation and stable driving effect, the support cap and the conductive rod can be rotated quickly and smoothly, thereby realizing rapid control of the conduction or disconnection of the circuit board, and further realizing rapid and accurate recording of the number of conduction times of the circuit board, thereby further improving the stability of the use of the electronic pen.

Detailed implementation manners

[0070] The following will further elaborate on the present application Figures 1 - 32 in conjunction with the attached drawings.

[0071] Embodiment 1 of the present application discloses an electronic pen.

[0072] Embodiment 1:

[0073] Referring to Figure 1 and Figure 2 , the electronic pen includes a pen tip 1, a pen tube 2, and a plug 3 arranged in sequence, and a refill 4 is arranged between the pen tube 2 and the pen tip 1.

[0074] Referring to Figure 2 and Figure 3 , the refill 4 includes a writing tip 41, an ink tube 42, and a limit ring 43. One end of the ink tube 42 is inserted into the pen tube 2, and the other end extends into the pen tip 1. One end of the writing tip 41 is inserted into the ink tube 42, and the other end extends to the outside of the pen tip 1. At the same time, the limit ring 43 is integrally formed and connected with the writing tip 41, and the limit ring 43 abuts against the ink tube 42.

[0075] Referring to Figure 4 and Figure 5 , a circuit board 5 is fixedly connected to the inner wall of the pen tube 2 near the plug 3, and two contacts 6 are welded to the surface of the circuit board 5 facing away from the plug 3. When the two contacts 6 are connected by a conductive metal or other conductive components, the circuit board 5 can be conducted.

[0076] Referring to Figure 4 and Figure 5, a trigger part 7 is arranged inside the pen tube 2. When the writing head 41 is squeezed and the ink tube 42 and the limit ring 43 move towards the circuit board 5, the trigger part 7 can conduct with the two contact heads 6, and the circuit board 5 is conducted. At the same time, an elastic reset part 8 is arranged inside the pen tube 2, and the reset part 8 can reset the writing head 41, the ink tube 42 and the limit ring 43, and open the circuit (non-conduction) between the trigger part 7 and the two contact heads 6, so that the circuit board 5 is open.

[0077] Refer to Figure 5 , a power supply 10 is fixedly connected to the inner wall of the plug cap 3, and the power supply 10 is electrically connected to the circuit board 5 to supply power to the circuit board 5. At the same time, a USB plug 11 penetrates through the plug cap 3. The USB plug 11 is fixedly connected to the plug cap 3, and the USB plug 11 is electrically connected to the power supply 10, so that the power supply 10 can be charged.

[0078] When a student starts writing, the writing head 41 is squeezed and the ink tube 42 and the limit ring 43 move towards the circuit board 5. Then the trigger part 7 conducts with the two contact heads 6, so that the circuit board 5 is conducted. When the student lifts the pen, the reset part 8 resets components such as the ink tube 42 and the writing head 41, and opens the circuit between the trigger part 7 and the two contact heads 6, so that the circuit board 5 is open. Repeating like this, by calculating how many words or strokes the student writes when the circuit board 5 is conducted once, and then recording the conduction times of the circuit board 5, the writing amount of the student can be estimated, which is convenient for educational institutions to formulate teaching tasks or control the homework amount of students.

[0079] Refer to Figure 4 and Figure 5 , the trigger part 7 includes a conductive block 71 arranged inside the pen tube 2, and the conductive block 71 can slide along the length direction of the pen tube 2. The conductive block 71 is made of conductive metal or conductive plastic material. One end of the conductive block 71 abuts against the end of the ink tube 42, and the other end can contact the two contact heads 6. When the ink tube 42 drives the conductive block 71 to move towards the circuit board 5, the conductive block 71 can contact and conduct with the two contact heads 6 to realize the conduction of the circuit board 5.

[0080] Refer to Figure 4 and Figure 5, the reset member 8 is a reset ring 81 made of rubber material, and the reset ring 81 is arranged along the circumferential direction of the pen tube 2. At the same time, one end of the reset ring 81 is connected to the inner wall of the pen tube 2, and the other end abuts against the conductive block 71. When the conductive block 71 moves towards the circuit board 5, the reset ring 81 deforms. When the student lifts the pen, the conductive block 71 drives components such as the ink tube 42 to reset under the elastic force of the reset ring 81, and the conductive block 71 is separated from the two contact heads 6 to achieve an open circuit of the circuit board 5. In other embodiments, the reset member 8 can also be a spring, silica gel or TPR elastomer, etc., as long as it has elasticity and can reset the conductive block 71 and components such as the ink tube 42.

[0081] Referring to Figure 2 , the pen tip 1 is detachably connected to the pen tube 2 so that the pen core 4 can be replaced. In this embodiment, the pen tip 1 and the pen tube 2 are connected by threads. In other embodiments, the pen tip 1 and the pen tube 2 can also be connected by snap connection or magnetic attraction, etc., as long as the pen tip 1 and the pen tube 2 can be detached.

[0082] Referring to Figure 2 , the pen tube 2 and the plug cap 3 are detachably connected to facilitate the installation or maintenance of the circuit board 5. In this embodiment, the pen tube 2 and the plug cap 3 are in snap-fit connection. In other embodiments, the pen tube 2 and the plug cap 3 can also be connected by threads or magnetic attraction, etc., as long as the pen tube 2 and the plug cap 3 can be detached.

[0083] The implementation principle of Embodiment 1 is as follows: When the student starts writing, the writing head 41 is squeezed and the ink tube 42, the limiting ring 43 and the conductive block 71 move towards the circuit board 5. When the conductive block 71 contacts the two contact heads 6, the circuit board 5 is turned on. When the student lifts the pen, the reset member 8 resets the writing head 41, the ink tube 42, the limiting ring 43 and the conductive block 71, and the conductive block 71 is separated from the two contact heads 6, so that the circuit board 5 is opened. Repeating like this, when the student writes a stroke or a character, the circuit board 5 is turned on once. By recording the number of times the circuit board 5 is turned on, the writing volume of the student can be estimated, which is convenient for educational institutions to formulate teaching tasks or control the homework volume of students. At the same time, this design can assist schools or educational institutions in controlling the learning status of students, facilitating timely reduction of the burden on students or adjustment of teaching plans, which is of great significance to the education cause.

[0084] At the same time, if the circuit board 5 is connected to a counter or a timer, parents or educational institutions can estimate the daily learning duration and learning task volume of students by observing the display of the counter or the timer, which is convenient for parents or educational institutions to control the daily learning tasks of students. At the same time, this design enables students to estimate the ink volume in the ink tube 42 by observing the display of the counter or the timer, so as to facilitate the timely replacement of the pen core 4 by students.

[0085] Embodiment 2:

[0086] Referring to Figure 6 and Figure 7 , the difference between this embodiment and Embodiment 1 is that: the triggering part 7 includes a conductive block 71 and a triggering tube 72. The conductive block 71 is made of conductive metal or conductive plastic and can slide along the length direction of the pen tube 2.

[0087] Referring to Figure 7 and Figure 8 , the triggering tube 72 is movably arranged in the pen tube 2 and can slide along the length direction of the pen tube 2. At the same time, the ink tube 42 is inserted into the triggering tube 72. One end of the triggering tube 72 abuts against the limiting ring 43, and the other end abuts against the conductive block 71.

[0088] When the student starts writing, the writing head 41 is squeezed and drives the limiting ring 43 and the ink tube 42 to move towards the circuit board 5. Then, the limiting ring 43 pushes the triggering tube 72 to drive the conductive block 71 to move towards the circuit board 5. When the conductive block 71 contacts the two contact heads 6, the circuit board 5 is turned on. When the student lifts the pen, the resetting member 8 drives the conductive block 71 to drive components such as the triggering tube 72 and the writing head 41 to reset. When the conductive block 71 separates from the two contact heads 6, the circuit board 5 is open.

[0089] Referring to Figure 7 and Figure 8 , the triggering tube 72 is made of metal material and is formed by turning processing to improve the accuracy of the processing length of the triggering tube 72. Compared with using the ink tube 42 with difficult-to-control length to push the conductive block 71 to move, this design is more accurate, thus reducing the problem that the circuit board 5 is always on or cannot be turned on. In other embodiments, the triggering tube 72 can also be formed by plastic injection molding or other methods, as long as it can be a hard material that can effectively control the length of the triggering tube 72 during production and processing.

[0090] The implementation principle of Embodiment 2 is: compared with using the ink tube 42 to push the conductive block 71 to move, since the length of the ink tube 42 is difficult to control, if the ink tube 42 is too long or too short, it is easy to cause the problem that the circuit board 5 is always on or cannot be turned on. In this embodiment, the limiting ring 43 and the writing head 41 of the pen core 4 are integrally formed, so that the processing accuracy of the limiting ring 43 is relatively high. At the same time, the triggering tube 72 is formed by plastic injection molding or metal turning processing, so that the processing length of the triggering tube 72 is relatively accurate, effectively reducing the risk that the circuit board 5 is always on or cannot be turned on, thereby improving the measurement accuracy and further improving the use stability of the electronic pen.

[0091] Embodiment 3:

[0092] Referring to Figure 9 and Figure 10, the difference between this embodiment and Embodiment 1 lies in that: the triggering part 7 includes a triggering tube 72, a supporting cap 73, a conductive rod 74 and two conductive posts 75.

[0093] Referring to Figure 9 , the triggering tube 72 is movably arranged in the pen tube 2 and can slide along the length direction of the pen tube 2. At the same time, the ink tube 42 is inserted into the triggering tube 72, and the triggering tube 72 abuts against the limiting ring 43.

[0094] Referring to Figure 9 and Figure 10 , the supporting cap 73 is sleeved on one end of the triggering tube 72 away from the limiting ring 43. The conductive rod 74 is made of conductive metal or conductive plastic, and the conductive rod 74 is fixedly embedded in the surface of the supporting cap 73 facing the circuit board 5.

[0095] Referring to Figure 9 and Figure 10 , the supporting cap 73 is rotatably sleeved on the triggering tube 72, and the two conductive posts 75 are respectively conductively connected to the corresponding contact heads 6. At the same time, a driving mechanism 9 capable of driving the supporting cap 73 to rotate is arranged in the pen tube 2. When the supporting cap 73 drives the conductive rod 74 to rotate, the two ends of the conductive rod 74 can contact or separate from the corresponding conductive posts 75 to realize the control of the conduction or open circuit of the circuit board 5.

[0096] Referring to Figure 10 and Figure 11 , the driving mechanism 9 includes a support frame 91 fixedly connected to the inner wall of the pen tube 2 close to the circuit board 5, and a control member 92 is arranged on the side wall of the support frame 91. The control member 92 includes a driving block 921 and a reset block 922, and the driving block 921 and the reset block 922 are respectively fixedly connected to the support frame 91. The driving block 921 is located between the circuit board 5 and the reset block 922, and the supporting cap 73 is located between the driving block 921 and the reset block 922.

[0097] Referring to Figure 10 and Figure 11 , a driving tooth part is arranged on the outer wall of the supporting cap 73 close to the driving block 921. The driving tooth part includes a driving wheel tooth 93 integrally formed and connected with the supporting cap 73. One side wall of the driving wheel tooth 93 is a driving inclined surface 13 and the other side wall is a limiting inclined surface 14.

[0098] Referring to Figure 10 and Figure 11, the end of the trigger tube 72 abuts against the top wall of the support cap 73, so that the trigger tube 72 can drive the support cap 73 to move towards the circuit board 5. At the same time, the driving inclined surface 13 abuts against the driving block 921, so that when the support cap 73 moves towards the circuit board 5, the support cap 73 can drive the conductive rod 74 to rotate under the action of the driving inclined surface 13 and the driving block 921 (the support cap 73 rotates to the right, that is, the driving block 921 is first located at point a and then at point b).

[0099] Refer to Figure 10 and Figure 11 , one end of the reset member 8 is fixedly connected or abuts against the support frame 91, and the other end abuts against the support cap 73, so that the reset member 8 can drive the support cap 73 to drive components such as the conductive rod 74 to move away from the circuit board 5.

[0100] Refer to Figure 10 and Figure 11 , a reset tooth portion is provided on the outer wall of the support cap 73 close to the reset block 922. The reset tooth portion includes a reset gear tooth 94 integrally formed with the support cap 73. One side wall of the reset gear tooth 94 is a forward rotation inclined surface 15, and the other side wall is a reverse rotation inclined surface 16.

[0101] Refer to Figure 10 and Figure 11 , the inclination direction and inclination angle of the reverse rotation inclined surface 16 are the same as those of the driving inclined surface 13, and the reverse rotation inclined surface 16 abuts against the reset block 922. When the support cap 73 moves away from the circuit board 5 under the drive of the reset member 8, the support cap 73 can drive the conductive rod 74 to rotate in the reverse direction and reset under the action of the reverse rotation inclined surface 16 and the reset block 922 (the support cap 73 rotates to the left, that is, the reset block 922 is first located at point c and then at point d), so as to realize the reciprocating rotation of the support cap 73.

[0102] Refer to Figure 10 and Figure 11 , one end of the conductive rod 74 penetrates through the corresponding driving gear tooth 93 and is located in the middle position of the corresponding driving inclined surface 13. The conductive column 75 penetrates through the support frame 91 and is fixedly connected to the support frame 91, and the end of the conductive column 75 can contact the corresponding end of the conductive rod 74. At the same time, when the support cap 73 rotates a certain angle, the end of the conductive rod 74 can contact the corresponding conductive column 75, so that when the electronic pen is in the storage state or the idle state, the problem that the conductive rod 74 is conducted with the corresponding conductive column 75 can be avoided as much as possible, thereby improving the measurement accuracy.

[0103] Refer to Figure 12 and Figure 13, the rotation axis of the support cap 73 is collinear with the center point on the surface of the support frame 91. The conductive rod 74 is located at the middle position on the surface of the support cap 73, and the axis of the conductive rod 74 passes through the rotation axis of the support cap 73. At the same time, the two conductive columns 75 are symmetrically distributed on both sides of the surface of the support frame 91, and when the conductive rod 74 rotates, both ends of the conductive rod 74 can contact the corresponding conductive columns 75.

[0104] Refer to Figure 14 and Figure 15 , the conductive rod 74 can also be located at the side position on the surface of the support cap 73, and the axis of the conductive rod 74 is located at the side of the rotation axis of the support cap 73. At the same time, the two conductive columns 75 are located at the side positions on the surface of the support frame 91, and the two conductive columns 75 correspond to both ends of the conductive rod 74 one by one, so that when the conductive rod 74 rotates, both ends of the conductive rod 74 can contact the corresponding conductive columns 75.

[0105] The implementation principle of Embodiment 3 is as follows: When the student starts writing, the writing head 41 is squeezed, and the limiting ring 43 drives components such as the trigger tube 72 and the support cap 73 to move towards the circuit board 5. Then, the support cap 73 drives the conductive rod 74 to rotate forward under the action of the driving block 921 and the driving inclined surface 13. When both ends of the conductive rod 74 contact the corresponding conductive columns 75 respectively, the circuit board 5 is turned on. As the support cap 73 continues to rotate forward, both ends of the conductive rod 74 are separated from the corresponding conductive columns 75 respectively, and then the circuit board 5 is opened.

[0106] When the student lifts the pen, the support cap 73 drives components such as the trigger tube 72 and the writing head 41 to move away from the circuit board 5 under the drive of the reset member 8. At the same time, the support cap 73 rotates reversely under the action of the reset block 922 and the reverse inclined surface 16. When both ends of the conductive rod 74 contact the corresponding conductive columns 75 respectively, the circuit board 5 is turned on again. As the support cap 73 continues to rotate reversely, when both ends of the conductive rod 74 are separated from the conductive columns 75 respectively, the circuit board 5 is opened again. This design enables the circuit board 5 to be turned on twice when the student writes a stroke or a character. By recording the number of times the circuit board 5 is turned on, the writing volume of the student can be estimated.

[0107] Embodiment 4:

[0108] Refer to Figure 16 and Figure 17 , the difference between this embodiment and Embodiment 3 is that: the control members 92 are provided in multiple numbers and are distributed along the circumferential direction of the support cap 73, and the driving gear teeth 93 and the reset gear teeth 94 are respectively provided in multiple numbers and are respectively distributed along the circumferential direction of the support cap 73.

[0109] Refer to Figure 16 and Figure 17, this embodiment only shows the states of two sets of control members 92, that is, there are two driving blocks 921 and two reset blocks 922, and the two driving blocks 921 and the two reset blocks 922 are symmetrically distributed on both sides of the support cap 73 respectively. At the same time, two driving gear teeth 93 and two reset gear teeth 94 are also used in this embodiment. The two driving gear teeth 93 correspond to the two driving blocks 921 one by one, and the two reset gear teeth 94 correspond to the two reset blocks 922 one by one.

[0110] Refer to Figure 16 and Figure 17 , both ends of the conductive rod 74 penetrate through the corresponding driving gear teeth 93 and are located at the middle positions of the corresponding driving inclined surfaces 13, so that the end of the conductive rod 74 can contact the corresponding conductive column 75 during the rotation of the support cap 73.

[0111] The implementation principle of Embodiment 4 is: by using the cooperation of multiple driving gear teeth 93, multiple reset gear teeth 94, multiple driving blocks 921 and multiple reset blocks 922, the support cap 73 is jointly driven to rotate reciprocally, effectively improving the driving stability of the support cap 73. At the same time, the multiple driving blocks 921 and the multiple driving blocks 921 can also play a certain supporting and limiting effect on the support cap 73, thereby improving the structural stability of the support cap 73.

[0112] Embodiment 5:

[0113] Refer to Figure 18 and Figure 19 , the difference between this embodiment and Embodiment 4 is that: there are multiple conductive rods 74, the number of conductive columns 75 is twice that of the conductive rods 74 respectively, and the multiple conductive columns 75 are respectively electrically connected to the corresponding contacts 6. This embodiment only shows the states of two conductive rods 74 and four conductive columns 75.

[0114] Refer to Figure 18 , both ends of the two conductive rods 74 penetrate through the corresponding driving gear teeth 93 and are located at the middle positions of the corresponding driving inclined surfaces 13, so that the end of the conductive rod 74 can contact the corresponding conductive column 75 during the rotation of the support cap 73.

[0115] Refer to Figure 18 , the two conductive rods 74 are located at the middle positions on the surface of the support cap 73, the two conductive rods 74 are cross-connected, and the axes of the two conductive rods 74 respectively pass through the rotation axis of the support cap 73.

[0116] Refer to Figure 16 and Figure 19, the four conductive posts 75 correspond to the respective ends of the two conductive rods 74 one by one, and the two conductive posts 75 located at both ends of the same conductive rod 74 are respectively electrically connected to different contacts 6. When the conductive rod 74 rotates, the two ends of the conductive rod 74 can contact the corresponding conductive posts 75, and the circuit board 5 is conducted.

[0117] Refer to Figure 20 and Figure 21 , the two conductive rods 74 can also be located on the side of the surface of the support cap 73, and the axes of the two conductive rods 74 are respectively located on the side of the rotation axis of the support cap 73. The four conductive posts 75 are located on the side of the surface of the support frame 91, and the four conductive posts 75 respectively correspond to the respective ends of the two conductive rods 74 one by one.

[0118] Refer to Figure 16 and Figure 21 , the two conductive posts 75 located at both ends of the same conductive rod 74 are respectively electrically connected to different contacts 6, so that when the conductive rod 74 rotates, the two ends of the conductive rod 74 can contact the corresponding conductive posts 75, and the circuit board 5 is conducted.

[0119] The implementation principle of Embodiment 5 is: by providing a plurality of conductive rods 74 and a plurality of conductive posts 75, as long as one of the conductive rods 74 contacts the corresponding two conductive posts 75, the circuit board 5 can be conducted, effectively improving the error tolerance rate, thereby improving the measurement accuracy.

[0120] Embodiment 6:

[0121] Refer to Figure 22 , Figure 23 and Figure 24 , the difference between this embodiment and Embodiment 4 is that the inclination direction of the forward rotation inclined surface 15 is opposite to that of the driving inclined surface 13, and when the support cap 73 moves away from the circuit board 5, the forward rotation inclined surface 15 can abut against the reset block 922, so that the support cap 73 can drive the conductive rod 74 to continue to rotate under the action of the forward rotation inclined surface 15 and the reset block 922, so as to realize the one-way rotation of the support cap 73.

[0122] Refer to Figure 23 and Figure 24 , in this embodiment, ten driving gear teeth 93 and ten reset gear teeth 94 are respectively adopted. The ten driving gear teeth 93 are evenly distributed along the circumferential direction of the support cap 73, and the head and tail are integrally formed and form a ring. The ten reset gear teeth 94 are evenly distributed along the circumferential direction of the support cap 73, and the head and tail are integrally formed and form a ring.

[0123] Refer to Figure 12 and Figure 23, the conductive rod 74 is located at the middle position on the surface of the support cap 73, and the axis of the conductive rod 74 passes through the rotation axis of the support cap 73.

[0124] Refer to Figure 13 and Figure 23 , two conductive columns 75 are symmetrically distributed on both sides of the surface of the support frame 91, and when the support cap 73 drives the conductive rod 74 to rotate, both ends of the conductive rod 74 can contact the corresponding conductive columns 75.

[0125] When the support cap 73 rotates 180°, the circuit board 5 can be conducted once. At the same time, since there are ten driving gear teeth 93, it can be obtained that when the student writes five strokes or five characters, the circuit board 5 is conducted once. By recording the number of times the circuit board 5 is conducted, the measurement of the student's writing volume can be achieved. In other embodiments, multiple driving gear teeth 93 and reset gear teeth 94 can also be used to achieve the function that the circuit board 5 can be conducted once when the student writes different strokes or different numbers of characters.

[0126] Refer to Figure 14 and Figure 23 , the conductive rod 74 can also be located on the side of the surface of the support cap 73, and the axis of the conductive rod 74 is located on the side of the rotation axis of the support cap 73.

[0127] Refer to Figure 15 and Figure 23 , two conductive columns 75 are located at the side position on the surface of the support frame 91, and when the conductive rod 74 rotates, both ends of the conductive rod 74 can contact the corresponding conductive columns 75.

[0128] When the support cap 73 rotates 360°, the circuit board 5 can be conducted once. At the same time, since there are ten driving gear teeth 93, it can be obtained that when the student writes ten strokes or ten characters, the circuit board 5 is conducted once. By recording the number of times the circuit board 5 is conducted, the measurement of the student's writing volume can be achieved. In other embodiments, multiple driving gear teeth 93 and reset gear teeth 94 can also be used to achieve the function that the circuit board 5 can be conducted once when the student writes different strokes or different numbers of characters.

[0129] The implementation principle of this embodiment is as follows: When a student starts writing and makes the support cap 73 move towards the circuit board 5, the driving block 921 abuts against the position a of the driving inclined surface 13. As the support cap 73 continues to move, the support cap 73 drives the conductive rod 74 to rotate forward under the action of the driving inclined surface 13 and the driving block 921 (the support cap 73 rotates to the right, and the driving block 921 is first located at the position a and then at the position b). During this process, the two ends of the conductive rod 74 first come into contact with the corresponding conductive columns 75, causing the circuit board 5 to conduct, and then when the two ends of the conductive rod 74 separate from the corresponding conductive columns 75, the circuit board 5 is opened. When the driving block 921 is located at the position b, the side wall of the driving block 921 abuts against the corresponding limiting inclined surface 14. At this time, the support cap 73 cannot rotate, and components such as the writing head 41 cannot move towards the circuit board 5. At the same time, the reset block 922 aligns with the position c of the forward rotation inclined surface 15.

[0130] When the student lifts the pen and the support cap 73 moves away from the circuit board 5 under the drive of the reset member 8, at this time, the reset block 922 abuts against the position c of the forward rotation inclined surface 15, and the driving block 921 separates from the corresponding limiting inclined surface 14. Subsequently, the support cap 73 drives the conductive rod 74 to continue rotating forward under the action of the forward rotation inclined surface 15 and the driving block 921 (the support cap 73 rotates to the right, that is, the reset block is first located at the position c and then at the position d). When the side wall of the reset block 922 abuts against the corresponding reverse rotation inclined surface 16 (the reset block 922 is located at the position d), the support cap 73 is completely reset, and the driving block 921 aligns with the position a of the next driving inclined surface 13. Repeating this process can achieve the unidirectional rotation of the support cap 73.

[0131] Embodiment 7:

[0132] Referring to Figure 23 and Figure 25 This embodiment is different from Embodiment 6 in that: there are multiple conductive rods 74, and only the states of two conductive rods 74 are shown in this embodiment. The two conductive rods 74 are located at the middle position of the surface of the support cap 73, the two conductive rods 74 are cross-connected, and the axes of the two conductive rods 74 respectively pass through the rotation axis of the support cap 73.

[0133] Referring to Figure 25 and Figure 26 When the support cap 73 drives the two conductive rods 74 to rotate, the two conductive rods 74 can sequentially come into contact with the two conductive columns 75.

[0134] The implementation principle of Embodiment 7 is as follows: When the support cap 73 drives the two conductive rods 74 to rotate, when the two ends of the first conductive rod 74 are respectively in contact with the corresponding conductive columns 75, the circuit board 5 is turned on. As the support cap 73 continues to rotate, when the two ends of the second conductive rod 74 are respectively in contact with the corresponding conductive columns 75, the circuit board 5 is turned on again. This process repeats. Since when a student writes one stroke or one character, the driving gear teeth 93 move forward once, according to how many driving gear teeth 93 move forward during the process of the circuit board 5 being turned on twice, it can be obtained how many strokes or characters the student writes when the circuit board 5 is turned on once. Subsequently, by recording the number of times the circuit board 5 is turned on, the writing volume of the student can be estimated. At the same time, by increasing the number of conductive rods 74 and adjusting the angle between adjacent two conductive rods 74, and then according to how many driving gear teeth 93 move forward during the process of the circuit board 5 being turned on twice, the function that the circuit board 5 can be turned on only after the student writes different strokes or different numbers of characters can be realized. Then, by recording the number of times the circuit board 5 is turned on, the writing volume of the student can be estimated.

[0135] Embodiment 8:

If three or more conductive rods 74 are used, the two ends of the multiple conductive rods 74 respectively extend outward to form a regular polygon structure, so that after the support cap 73 rotates a specific angle, the conductive rod 74 can contact and conduct with the corresponding conductive column 75.

[0137] The implementation principle of Embodiment 8 is as follows: Since the circuit board 5 can be turned on only after the conductive rod 74 rotates a specific angle, then according to how many strokes or characters the student writes before the circuit board 5 is turned on once, and then according to the number of times the circuit board 5 is turned on, the writing volume of the student can be estimated.

[0144] The implementation principle of Embodiment 9 is as follows: When the support cap 73 drives the conductive rod 74 to rotate, the two ends of the conductive rod 74 respectively contact the corresponding conductive columns 75, and the circuit board 5 is conducted. As the support cap 73 rotates, the conductive rod 74 contacts the other two adjacent conductive columns 75, and the circuit board 5 is conducted again. In this way, intermittent conduction of the circuit board 5 can be achieved. At this time, according to how many strokes or how many characters the student writes when the circuit board 5 is conducted once, and then according to the conduction times of the circuit board 5, the writing volume of the student can be estimated.

[0148] Referring to Figure 25 and Figure 30, if six conductive posts 75 are used and the connection lines between the six conductive posts 75 form a regular hexagon, when the support cap 73 drives the two conductive rods 74 to rotate, the two end portions of one of the conductive rods 74 can contact the corresponding conductive post 75.

[0152] Refer to Figure 31 and Figure 32 , if two conductive rods 74 are used, the two conductive rods 74 are symmetrically distributed on both sides of the end face of the support cap 73. If three or more conductive rods 74 are used, the two ends of the multiple conductive rods 74 can form a regular polygon structure after extension, and the connection lines between the multiple conductive posts 75 can also form a regular polygon structure, so that after the support cap 73 rotates a specific angle, the conductive rods 74 can contact and conduct with the corresponding conductive posts 75.
