Detailed implementation manners
[0064] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.
[0065] In the description of the present application, it should be understood that the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, the meaning of "a plurality" is two or more, and at least one means one, two or more, unless otherwise specifically defined.
[0066] Electronic pens are widely used in fields such as tablet computers, office computers, and mobile phones. Existing electronic pens generally include an electrode assembly for transmitting and receiving signals. The electrode assembly usually includes a transmitting electrode, a receiving electrode, and other structures. The transmitting electrode emits signals, and the receiving electrode receives signals. Structurally, for the transmitting electrode, a metal part is built into the tip of the electronic pen as the transmitting end of the transmitting electrode. This metal part is connected to the transmitting electrode, and the transmitting electrode is connected to the main board through forms such as FPC. During operation, the main board emits an electrical signal to the metal part inside the pen tip. This metal part is generally a metal ball head, and the metal ball head forms an electric field. The change in the electric field is read by the host device (such as a tablet), generating a writing reaction. Structurally, for the receiving electrode, it is also connected to the main board through an elastic metal conductive structure such as a spring and FPC. During operation, the receiving electrode receives the electric field change signal from the host device and transmits it to the main board, causing the electronic pen to react. The receiving electrode can also be used as a transmitting electrode, enabling the host device to detect the tilt of the pen and reflect functions such as different writing thicknesses. Existing electrode assemblies are usually integrated into one component through forms such as injection molding and electroplating, and then the electrode circuit is conducted to the main board through structures such as elastic sheets or FPC. When injecting the electrode assembly, different processing materials need to be injected into the mold, and the injection molding process is difficult and prone to incorrect operations, resulting in defective electrode assemblies. Therefore, the current structure of the electrode assembly is not reasonably set, which will lead to greater difficulty in its production and processing and a lower yield rate.
[0067] In view of this, the embodiments of the present application provide an electronic pen to overcome at least one of the above technical problems.
[0068] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5, in the embodiment of the present application, the electronic pen includes: a pen body housing 10, a first electrode 20, a second electrode 30, and an insulating member 40. The first electrode 20, the second electrode 30, and the insulating member 40 can be assembled to form an electrode assembly. The pen body housing 10 generally includes the outer shell of the electronic pen and a pen tube located inside the outer shell. The electrode assembly can be connected to the pen tube, and then the pen tube is embedded inside the outer shell and connected to the outer shell. The pen body housing 10 has a first accommodation cavity 11, and the electrode assembly can be installed inside the first accommodation cavity 11. At least a part of the first electrode 20 is located inside the first accommodation cavity 11. The first electrode 20 can be completely located inside the first accommodation cavity 11, or a part of it can be embedded inside the first accommodation cavity 11, such that one end of the first electrode 20 is located outside the first accommodation cavity 11, making one end of the first electrode 20 closer to a touch device such as a tablet or a mobile phone, which is more convenient for the signal connection between the first electrode 20 and the touch device. The first electrode 20 has a connection hole 21 communicating with the first accommodation cavity 11. The second electrode 30 passes through the connection hole 21, without additionally occupying the space of the first accommodation cavity 11, making the installation of the structure more compact. The second electrode 30 is arranged at an interval from the first electrode 20 to avoid interference between the two electrodes and affect the signal transmission.
[0069] The insulating member 40 is inserted through the connection hole 21 and connected to the second electrode 30, which can also make the installation of the electrode assembly structure more compact. The insulating member 40 includes an insulating base 41 and an insulating cover 42 connected to each other. At least part of the insulating base 41 and the insulating cover 42 is connected to the first electrode 20, so as to facilitate the connection of the insulating base 41, the insulating cover 42 and the first electrode 20 together and improve the stability of the structural connection. The insulating base 41 and the insulating cover 42 enclose a placement cavity 43 communicating with the first accommodation cavity 11, and the second electrode 30 is inserted through the placement cavity 43. This structural setting form makes the first electrode 20, the second electrode 30, the insulating base 41 and the insulating cover 42 be compactly arranged, and by setting corresponding cavities, it is convenient for these structures to be assembled into an electrode assembly. At the same time, the first electrode 20, the second electrode 30, the insulating base 41 and the insulating cover 42 are set as independent structures, so that these simple structures can be separately produced and processed, and then an electrode assembly can be formed through simple assembly. During assembly, the second electrode 30 can be first installed on the insulating base 41, and then the insulating cover 42 can be covered on the insulating base 41. The insulating base 41 and the insulating cover 42 can enclose a placement cavity 43 for placing the second electrode 30; after the second electrode 30 is installed on the insulating member 40, the insulating member 40 is then passed through the inside of the first electrode 20, so that part of the insulating member 40 is located in the connection hole 21, and the first electrode 20, the second electrode 30, the insulating base 41 and the insulating cover 42 are assembled. Since the structure of each fitting is relatively simple, and each simple structure is formed by processing the same material, it is more convenient during production and processing. The processing technology of a single structure is simple, the cost is low, defective products are not likely to appear, and it is not necessary to injection-mold the electrode assembly with different materials. Therefore, the electrode assembly is assembled by multiple simple structures, which ensures the normal use of the electrode assembly, makes its structure setting more reasonable, reduces the production and processing difficulty of the electrode assembly, and can improve its yield rate.
[0070] Please refer to Figure 1 、 Figure 6 and Figure 8 , in some embodiments, the electronic pen includes: a main board member 50, a plurality of connecting members 60 and a third electrode 70.
[0071] The main board member 50 is located within the first accommodation cavity 11. The main board member 50 is connected to the insulating member 40 for mounting on the insulating member 40, and is welded to the first electrode 20 and the second electrode 30 to form an electrical connection, enabling the first electrode 20 and the second electrode 30 to transmit or receive signals. The main board member 50 generally includes a reinforcing plate, an FPC, and a main board (not shown in the figure). The FPC is electrically connected to the main board. Since the FPC is relatively flexible, it can be partially connected to the reinforcing plate, and then the reinforcing plate is connected to the insulating member 40, which facilitates the installation of the FPC and improves the stability of FPC installation. A plurality of connecting members 60 are all located within the first accommodation cavity 11 and penetrate through the main board member 50, the insulating member 40, and the first electrode 20 to fixedly connect the main board member 50, the insulating member 40, and the first electrode 20. The connecting member 60 can be a metal screw, and the number can be one or more. The connecting member 60 can sequentially penetrate through the FPC, the reinforcing plate, the insulating seat 41 of the insulating member 40, the insulating cover 42, and the first electrode 20, thereby connecting the FPC, the reinforcing plate, the insulating seat 41, the insulating cover 42, and the first electrode 20 together.
[0072] The third electrode 70 penetrates through the connection hole 21 and is electrically connected to the main board member 50 through at least one connecting member 60. The third electrode 70 is electroplated on the outer periphery of the insulating member 40 and extends along the length direction X of the electronic pen. The third electrode 70 is spaced apart from the first electrode 20 and the second electrode 30. The third electrode 70 is used to receive signals or transmit signals. That is to say, the third electrode 70 can be electroplated on the outer periphery of the insulating member 40, and the third electrode 70 extends along the length direction X of the electronic pen, so as to penetrate through the connection hole 21 and be electrically connected to one or more connecting members 60. The connecting member 60 is electrically connected to the main board member 50, enabling the third electrode 70 to be electrically connected to the main board member 50, endowing the third electrode 70 with the ability to transmit signals or receive signals, which is the same as the nature of the first electrode 20 and the second electrode 30. If the third electrode 70 can transmit signals, it can transmit corresponding signals to a touch device such as a tablet or a mobile phone simultaneously with another electrode (the first electrode 20 or the second electrode 30) to enhance the intensity of the transmitted signal and avoid interference from external factors to the transmitted signal. The third electrode 70 can also be used as an electrode for receiving signals, and together with another electrode (the first electrode 20 or the second electrode 30), it can receive the corresponding signals transmitted by a touch device such as a tablet or a mobile phone, and can better capture the signal and improve the ability to receive signals.
[0073] Please refer to Figure 1 、 Figure 6 and Figure 8, in some embodiments, along the length direction X of the electronic pen, the insulating member 40 includes a first end 44 away from the main board member 50. A part of the third electrode 70 is electroplated on the first end 44 and is disposed around the outer periphery of the first end 44. When the electronic pen is in use, the first end 44 of the insulating member 40 away from the main board member 50 is closer to the touch device. By providing a part of the third electrode 70 on the first end 44, the third electrode 70 can better transmit or receive signals. At the same time, a part of the third electrode 70 is disposed around the first end 44, and this setting form can increase the range of the third electrode 70 transmitting or receiving signals, thereby further enhancing the intensity of the received or transmitted signals of the electronic pen.
[0074] Please refer to Figure 1 and Figure 7 , in some embodiments, the main board member 50 is connected to the side of the insulating cover 42 away from the insulating base 41. The insulating member 40 has a placement hole 45 that penetrates through the insulating base 41 and the insulating cover 42. At this time, a part of the main board member 50 and the first electrode 20 can be connected through the placement hole 45. The first electrode 20 includes: a body portion 22 and an elastic portion 23.
[0075] The body portion 22 is at least partially located in the first accommodation cavity 11 and is at least partially connected to the insulating member 40. The body portion 22 has a connection hole 21, and the insulating member 40 penetrates through the inside of the connection hole 21. A part of the body portion 22 is located on the side of the insulating member 40 away from the main board member 50. The elastic portion 23 is disposed in the placement hole 45, and the elastic portion 23 is in a compressed state, so that the elastic portion 23 abuts against the body portion 22 to prevent its rebound and achieve tight contact and not easy to loosen, improving the connection stability between the elastic portion 23 and the body portion 22. The elastic portion 23 is respectively welded to the body portion 22 and the main board member 50, thereby realizing the conduction of electrical signals. Through this welding form, the connection stability between the elastic portion 23 and the main board member 50 can be improved, replacing the original connection form of using a spring piece to abut against the main board member 50. The original setting form is prone to dislocation between the spring piece and the main board member 50 when the electronic pen is impacted, resulting in a disconnection situation. By welding, the connection stability can be improved and the risk of disconnection can be reduced.
[0076] Please refer to Figure 1 and Figure 8 , in some embodiments, the electronic pen includes: a mounting seat 80 and a spacer 90.
[0077] The mounting base 80 is located within the first accommodation cavity 11 and can be connected to the pen body housing 10 through other structures. It can be used as a grounding electrode, playing a certain role in electrostatic protection to prevent static electricity from interfering with or damaging the internal structure of the electronic pen. The mounting base 80 has a fixing cavity 81 communicating with the first accommodation cavity 11, and at least part of the first electrode 20, the insulating member 40, and the main board member 50 are located within the fixing cavity 81, thereby facilitating the installation of the first electrode 20, the second electrode 30, the insulating member 40, and the main board member 50 within the pen body housing 10. The isolating member 90 is located within the fixing cavity 81. The isolating member 90 is respectively connected to the mounting base 80 and the first electrode 20 and is disposed between the mounting base 80 and the first electrode 20 to isolate the mounting base 80 and the first electrode 20. The isolating member 90 is a component made of insulating material and is disposed between the mounting base 80 and the first electrode 20 to isolate the mounting base 80 and the first electrode 20, preventing the electrical signal on the first electrode 20 from being transmitted to the mounting base 80 and ensuring the accurate transmission of the electrical signal on the first electrode 20.
[0078] Please refer to Figure 1 and Figure 8, in some embodiments, the spacer 90 may be a component made of an insulating material. The spacer 90 connects the first electrode 20 through a plurality of connecting members 60. Among them, the connecting member 60 connected to the third electrode 70 is insulated from the mounting base 80 through the spacer 90. The connecting member 60 electrically connected to the third electrode 70 sequentially penetrates through the main board member 50, the insulating member 40, and the first electrode 20 to connect the three. At the same time, it can also be embedded into the spacer 90 to fixedly connect the spacer 90 and the first electrode 20. The connecting member 60 can not only play the role of electrical signal conduction but also play the role of connecting other structures, which can reduce the use of fixing structures, reduce costs, save the space occupied inside the electronic pen, and make the volume of the electronic pen smaller. The connecting member 60 electrically connected to the third electrode 70 is insulated from the mounting base 80 through the spacer 90. A part of the spacer 90 extends downward (extends perpendicular to the length direction) to form a sleeve-like or tubular structure, and this part surrounds or wraps one end of the connecting member 60 close to the mounting base 80, so as to better isolate the connecting member 60 and the mounting base 80 and prevent the connecting member 60 electrically connected to the third electrode 70 from being conducted to the mounting base 80. Since the mounting base 80 is connected to the pen body housing 10 and plays a grounding role, this setting method of the spacer 90 can prevent the electrical signals transmitted on the main board member 50 and the third electrode 70 from being transmitted to the mounting base 80 and ensure the realization of the function of the third electrode 70. The connecting member 60 not electrically connected to the third electrode 70, after sequentially penetrating through the main board member 50, the insulating member 40, and the first electrode 20, can further penetrate through the spacer 90 and the mounting base 80 and be connected to the mounting base 80, thereby connecting the main board member 50, the insulating member 40, the first electrode 20, the spacer 90, and the mounting base 80 together. There is no need to use other fixing structures to connect the spacer 90 and the mounting base 80, which reduces the use of fixing structures, reduces costs, and saves the space occupied inside the electronic pen.
[0079] Please refer to Figure 7 and Figure 9 , in some embodiments, the electronic pen further includes: a tip housing 100 and a conducting member 110.
[0080] The nib housing 100 is at least partially embedded in the first accommodation cavity 11 and is connected to the first electrode 20. The nib housing 100 has a second accommodation cavity 101 communicating with the first accommodation cavity 11. A part of the first electrode 20, the second electrode 30, and the insulating member 40 are all embedded in the second accommodation cavity 101, facilitating connection with the internal structure of the nib housing 100. The conduction member 110 is embedded in the second accommodation cavity 101 and is fixedly connected to the nib housing 100 to improve the stability of the conduction member 110. The conduction member 110 abuts against the second electrode 30 and is electrically connected to the second electrode 30, enabling the electrical signal on the second electrode 30 to be conducted to the conduction member 110 and transmitting a signal to the touch device through the conduction member 110. The conduction member 110 is located at the nib position of the electronic pen. When the electronic pen is in use, the conduction member 110 is extremely close to the touch device, and the effect of transmitting or receiving a signal can be improved through the conduction member 110.
[0081] Please refer to Figure 7 、 Figure 9 and Figure 10 , in some embodiments, the conduction member 110 includes: a first conduction part 111, a second conduction part 112, and a pressing part 113.
[0082] The first conduction part 111 is embedded in the second accommodation cavity 101 and is located at a position close to the nib in the second accommodation cavity 101. The first conduction part 111 is fixedly connected to the nib housing 100 to improve the stability of the first conduction part 111. The first conduction part 111 has a third accommodation cavity 1111 communicating with the second accommodation cavity 101. The second conduction part 112 is at least partially located in the third accommodation cavity 1111. One end of the second conduction part 112 abuts against the second electrode 30 and is electrically connected to the second electrode 30, thereby realizing the conduction between the second electrode 30 and the conduction member 110. The pressing part 113 is located in the third accommodation cavity 1111 and is respectively connected to the first conduction part 111 and the second conduction part 112. The pressing part 113 can be an elastic metal part such as a spring, which can transmit the electrical signal on the second conduction part 112 to the first conduction part 111. At this time, the pressing part 113 is in a compressed state, pressing the second conduction part 112 to make the second conduction part 112 abut against the second electrode 30, improving the stability of the abutment between the two and preventing them from separating easily, ensuring the normal conduction of the electrical signal.
[0083] Please refer to Figure 2 、 Figure 11 、 Figure 12 and Figure 13, in some embodiments, the nib housing 100 has a groove portion 102 communicating with the second accommodation cavity 101. One side of the second electrode 30 facing the conduction member 110 has a connection groove 31 communicating with the second accommodation cavity 101. The second electrode 30 can be a metal rod structure, and the connection groove 31 is formed on the side of the metal rod facing the conduction member 110; the second electrode 30 can also be a spring structure, and the connection groove 31 is the inner space of the spring structure. The conduction member 110 is a solid metal part with high strength and is not easily deformed when impacted. Compared with the original pin conduction structure, the solid metal part conduction structure is simpler in structure, easier to process, has a higher yield rate in production, and lower cost. The conduction member 110 includes: a main body portion 114, a flange portion 115, and a tip portion 116.
[0084] The main body portion 114 is the main structure of the conduction member 110, which is embedded in the second accommodation cavity 101, located at a position in the second accommodation cavity 101 close to the nib, and is connected to the nib housing 100. The flange portion 115 has an annular structure and is fixedly connected around the outer periphery of the main body portion 114. The number of the flange portions 115 is the same as the number of the groove portions 102, and the positions of the flange portions 115 correspond to the positions of the groove portions 102. The flange portion 115 is embedded into the inside of the groove portion 102 and is engaged with the corresponding groove portion 102, thereby improving the stability of the main body portion 114, preventing its position from shifting after being impacted, and ensuring stable conduction between the conduction member 110 and the second electrode 30. The tip portion 116 is located in the second accommodation cavity 101 and is connected to one side of the main body portion 114 facing the second electrode 30. At least part of the tip portion 116 is embedded in the connection groove 31 and abuts against the second electrode 30. Through the cooperation between the tip portion 116 and the connection groove 31, the tip portion 116 is limited, preventing dislocation between the tip portion 116 and the second electrode 30, and preventing the conduction member 110 from being impacted resulting in an open circuit between the second electrode 30 and the conduction member 110, which can further improve the connection stability between the conduction member 110 and the second electrode 30.
[0085] Please refer to Figure 11 and Figure 15 , in some embodiments, the nib housing 100 has a clamping hole 103 communicating with the first accommodation cavity 11 and the second accommodation cavity 101. The first electrode 20 includes a clamping portion 24 corresponding to the clamping hole 103, and the clamping portion 24 is embedded in the clamping hole 103. The nib housing 100 was originally connected to the pen body housing 10 or other structures on the electronic pen by a thread, and it was easy to get stuck when the nib housing 100 was installed. Through the clamping connection between the clamping portion 24 of the first electrode 20 and the clamping hole 103 of the nib housing 100 in this application, the nib housing 100 and the first electrode 20 can be quickly connected, the connection efficiency can be improved, and there will be no stuck situation, which can extend the service life of the nib housing 100 while ensuring stable assembly.
[0086] Please refer to Figure 8 and Figure 14 In some embodiments, the placement cavity 43 includes a first cavity 431 and a second cavity 432. The insulating base 41 has the first cavity 431, the insulating cover 42 has the second cavity 432, and the second electrode 30 passes through the first cavity 431 and the second cavity 432. When installing the second electrode 30, it can be first placed in the first cavity 431, and then the insulating cover 42 is covered on the insulating base 41 so that the insulating base 41 and the insulating cover 42 can wrap a part of the second electrode 30. The insulating base 41 has a positioning groove 411, and the setting of the positioning groove 411 does not affect the placement of the second electrode 30. The insulating member 40 includes a positioning portion 46 connected to the insulating cover 42. The number of the positioning portions 46 is the same as the number of the positioning grooves 411 and the positions correspond to each other so that the positioning portion 46 can be embedded in the corresponding positioning groove 411. During the assembly of the electrode assembly, after the second electrode 30 is placed in the first cavity 431, the insulating base 41 and the insulating cover 42 can be positioned and connected through the positioning portion 46 and the positioning groove 411, avoiding the position deviation between the two when the insulating base 41 and the insulating cover 42 are installed inside the first electrode 20 and improving the assembly stability of the insulating base 41 and the insulating cover 42.
[0087] Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 In some embodiments, the insulating base 41 includes a connected bearing body 412 and a surrounding end 413. At least part of the bearing body 412 and the surrounding end 413 is located in the connection hole 21 and is at least partially connected to the first electrode 20. The bearing body 412 has a bearing groove 4121, and the surrounding end 413 has a constraint hole 4131 communicating with the bearing groove 4121. A part of the second electrode 30 is embedded in the bearing groove 4121 and passes through the constraint hole 4131. When installing the second electrode 30, it can be embedded in the bearing groove 4121 and also in the constraint hole 4131. The surrounding end 413 is disposed around the outer periphery of the second electrode 30, which can play a certain constraining role on the second electrode 30, avoiding the position deviation of the second electrode 30 during assembly and ensuring the stability of the second electrode 30. The insulating cover 42 has a covering groove 421 communicating with the bearing groove 4121. A part of the second electrode 30 is embedded in the covering groove 421. The covering groove 421, the bearing groove 4121 and the constraint hole 4131 form the placement cavity 43. After the second electrode 30 is installed on the insulating base 41, a part of the second electrode 30 can be covered by the insulating cover 42, so that a part of the second electrode 30 is embedded in the covering groove 421, further improving the assembly stability of the second electrode 30.
[0088] Please refer to Figure 1, in an embodiment of the present application, an electronic pen is further provided. The electronic pen includes: a pen body housing 10, a first electrode 20, a second electrode 30, an insulating member 40, and a sensing member 120. Among them, the first electrode 20, the second electrode 30, and the insulating member 40 can be assembled to form an electrode assembly. The pen body housing 10, the first electrode 20, the second electrode 30, and the insulating member 40 are the same as the structures in the above embodiment, with simple production and processing, low cost, and high yield. These structures can also form an electrode assembly through simple assembly. Thereby reducing the cost of the electrode assembly and improving the yield.
[0089] The pen body housing 10 generally includes the outer shell of the electronic pen and the pen tube located inside the outer shell. The electrode assembly can be connected to the pen tube, and then the pen tube is embedded inside the outer shell to connect the pen tube and the outer shell. The pen body housing 10 has a first accommodation cavity 11, which can be used to install the electrode assembly inside the first accommodation cavity 11. The first electrode 20 is at least partially located inside the first accommodation cavity 11, and the first electrode 20 has a connection hole 21 communicating with the first accommodation cavity 11. The second electrode 30 passes through the connection hole 21 and is arranged at an interval from the first electrode 20. The first electrode 20 can be completely located inside the first accommodation cavity 11, or a part of it can be embedded inside the first accommodation cavity 11, so that one end of the first electrode 20 is located outside the first accommodation cavity 11, making one end of the first electrode 20 closer to touch devices such as tablets and mobile phones, which is more convenient for the signal connection between the first electrode 20 and the touch device. The first electrode 20 has a connection hole 21 communicating with the first accommodation cavity 11. The second electrode 30 penetrates through the connection hole 21, without additionally occupying the space of the first accommodation cavity 11, making the installation of the structure more compact. The insulating member 40 passes through the connection hole 21. The insulating member 40 has a placement cavity 43 for the second electrode 30 to pass through, and the insulating member 40 is connected to the second electrode 30. The insulating member 40 can also be composed of an insulating base 41 and an insulating cover 42. By isolating the first electrode 20 and the second electrode 30 through the insulating member 40, interference between these two electrodes can be avoided. The sensing member 120 is located inside the first accommodation cavity 11 and is respectively connected to the pen body housing 10 and the first electrode 20, and is used to sense the acting force transmitted by the first electrode 20. When the electronic pen is writing, the nib part thereof is connected to the first electrode 20 (the structure of the nib part is the same as the structure of the above-mentioned nib housing 100 and the conduction member 110). The nib part will transmit the acting force received to the sensing member 120 through the first electrode 20. The sensing member 120 senses the acting force information transmitted by the first electrode 20, and then transmits the sensed information to the main board member 50 connected to it (the same as the above-mentioned main board member 50), and the main board member 50 processes the information. By arranging the sensing member 120 on the basis of the original electrode assembly structure, the function of the electronic pen is increased. While the production cost of the electrode assembly on the electronic pen is reduced and the yield rate is improved, the sensing structure set on the electronic pen is made simpler, and it only needs to be respectively connected to the pen body housing 10 and the mounting seat 80, reducing the setting difficulty.
[0090] Please refer to Figure 1 , in some embodiments, the electronic pen further includes a mounting seat 80. The first electrode 20 is connected to the sensing member 120 through the mounting seat 80, that is to say, the first electrode 20 transmits the acting force to the sensing member 120 through the mounting seat 80. The sensing member 120 includes a deformation part 121 and a sensing part 122.
[0091] The deformation part 121 includes a connected lapping section 1211 and a deformation section 1212. The lapping section 1211 extends along the length direction X of the electronic pen and can be connected to the mounting seat 80 in forms such as bolts and buckles, facilitating the first electrode 20 to transfer the acting force to the lapping section 1211 through the mounting seat 80. The deformation section 1212 extends along a first direction Y intersecting with the length direction X. Preferably, the length direction X intersects with the first direction Y. One side of the deformation section 1212 away from the lapping section 1211 is connected to the pen body housing 10. The first electrode 20 transfers the acting force to the deformation section 1212 through the mounting seat 80 and the lapping section 1211, causing the deformation section 1212 to deform. Equivalently, one side of the deformation section 1212 is connected to the lapping section 1211 and the other side is connected to the pen body housing 10. When the lapping section 1211 receives the acting force from the mounting seat 80, it will transfer the acting force to the deformation section 1212, causing the deformation section 1212 to deform. Meanwhile, the sensing part 122 is connected to the deformation section 1212. The sensing part 122 can be a strain gauge, generally attached to the deformation section 1212. The sensing part 122 will deform as the deformation section 1212 deforms. It is usually made of a sensitive material, such as a thin film or a metal foil. When subjected to an external force, the sensing part 122 will undergo corresponding deformation, resulting in changes in its characteristics such as resistance, capacitance, or inductance. The sensing part 122 is used to sense the acting force information on the deformation section 1212 and then convert it into an electrical signal and transmit it to the main board member 50 for processing.
