[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use.

Furthermore, all other embodiments obtained by those skilled in the art without inventive effort are within the protection scope of the present utility model.

[0020] Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of this utility model specification.

[0021] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Example 1 This application provides an electronic pen, such as Figures 1 to 4 As shown, the electronic pen includes a pen body 10, a conductive component 20, and a charging contact 30. The pen body 10 has a receiving cavity, and a first through hole 101 communicating with the receiving cavity is opened on the side wall of the pen body 10. The conductive component 20 is disposed in the receiving cavity and has a hollow structure 201. The charging contact 30 is provided with a contact portion 301, a connecting portion 302, and a limiting portion 303. At least a portion of the contact portion 301 is embedded in the pen body 10. One end of the connecting portion 302 is connected to the contact portion 301, and the other end is connected to the limiting portion 303. Specifically, the connecting portion 302 passes through the first through hole 101 and the hollow structure 201. The limiting portion 303 is located on the side of the conductive member 20 away from the contact portion 301, and the contact portion 301 is electrically connected to the conductive member 20. The contact portion 301 contacts the charging member outside the pen body 10. The contact portion 301 and the limiting portion 303 are located on both sides of the first through hole 101. The conductive member 20 is located between the first through hole 101 and the limiting portion 303, so that the limiting portion 303 is limited by the hollow structure 201 to prevent the charging contact 30 from moving out of the pen body 10.

[0023] The contact portion 301 is exposed outside the pen body 10 so that it can contact the power supply contacts of the external power supply device of the electronic pen, thereby forming a power supply path between the power supply device, the power supply contacts, and the conductive component 20. Specifically, in some embodiments, the contact portion 301, the connecting portion 302, and the limiting portion 303 can be made of the same conductive metal material. The connecting portion 302 passes through the hollow structure 201, and the sidewall of the hollow structure 201 abuts against the connecting portion 302 to achieve electrical connection between the contact portion 301 and the conductive component 20. In other embodiments, the contact portion 301, the connecting portion 302, and the limiting portion 303 can be integrally injection molded. The integral injection molded part is coated with a conductive plating layer. The connecting portion 302 passes through the hollow structure 201, and the sidewall of the hollow structure 201 abuts against the connecting portion 302 to achieve electrical connection between the contact portion 301 and the conductive component 20. In some embodiments, the contact portion 301, the connecting portion 302, and the limiting portion 303 are integrally injection molded parts. A conductive element is embedded in the contact portion 301, with one end of the conductive element exposed on the side of the contact portion 301 away from the limiting portion 303, so that it can contact the power supply contact of the power supply device. The other end of the conductive element extends through the outer wall of the connecting portion 302 and wraps around the outer wall of the connecting portion 302, so that when the side wall of the hollow structure 201 abuts against the connecting portion 302, the power supply contact of the external power supply device of the pen body 10 and the conductive component 20 can achieve electrical connection. As long as the connecting portion 302 passes through the hollow structure 201, and the side wall of the hollow structure 201 abuts against the connecting portion 302, the contact portion 301 and the conductive component 20 can achieve electrical connection. The embodiments of this application do not limit this.

[0024] Understandably, through the structural cooperation of the electronic pen body 10, the first through hole 101, and the conductive component 20, the connecting part 302 of the charging contact 30 can pass through the first through hole 101 and the hollow structure 201. At the same time, by utilizing the design of the limiting part 303 located on the side of the conductive component 20 away from the contact part 301 and the contact part 301 being electrically connected to the conductive component 20, on the one hand, the limiting part 303 is located on the side of the hollow structure 201 away from the first through hole 101 to restrict the charging contact 30 from moving outward from the pen body 10, and the contact part 301 is located on the side of the first through hole 101 away from the limiting part 303 to restrict the charging contact 30 from moving inward from the pen body 10. This effectively solves the problem of loosening after long-term use that is easily caused by relying solely on interference fit or glue fixation in the prior art, and greatly improves the assembly stability of the charging contact 30. On the other hand, there is no need to add additional fixing parts or complex conductive connectors. While simplifying the internal structure of the electronic pen and saving the space of the cavity, the electrical connection between the conductive component 20 and the charging contact 30 ensures the stable conduction of the power supply path and improves the long-term reliability of the electronic pen's charging function.

[0025] In some embodiments, based on the first embodiment described above, the hollow structure 201 is a through-hole structure, and the limiting part 303 can be made of a highly elastic and restorative conductive material. In its initial state, the outer periphery of the limiting part 303 is larger than the outer periphery of the hollow structure 201. The limiting part 303 can have multiple elastic petals that can retract towards the center distributed circumferentially, and each elastic petal has an outwardly protruding arc-shaped locking platform at its end. The width direction of the electronic pen is the first direction X. During assembly, the limiting part 303 passes through the first through-hole 101 and the hollow structure 201 along the first direction X. During this process, the elastic petals are squeezed towards the center by the edge of the hollow structure 201, allowing the limiting part 303 to pass smoothly. After passing through completely, the elastic petals unfold under their own elastic restoring force, and the arc-shaped locking platform protrudes outward. At this time, the outer periphery of the locking platform is larger than the outer periphery of the hollow structure 201, and it abuts against the side surface of the conductive component 20 away from the contact part 301 to form a blockage, cooperating with the contact part 301.

[0026] Example 2 In one embodiment, the connecting portion 302 in the aforementioned embodiment 1 of this application passes through the hollow structure 201 and is snapped into the conductive component 20.

[0027] Specifically, in one embodiment, the hollow structure 201 is a through hole structure, and the outer diameter of the connecting part 302 is slightly larger than the inner diameter of the hollow structure 201. During assembly, the connecting part 302 passes through the first through hole 101 and the hollow structure 201 along the first direction X, and the connecting part 302 is interference-fitted with the hollow structure 201 so that the connecting part 302 is snapped into the conductive component 20.

[0028] In other embodiments, the hollow structure 201 is a groove structure. The length direction of the electronic pen is the second direction Y. Along the second direction Y, the groove structure is located at the end of the conductive component 20 near the tip of the electronic pen. The opening of the groove structure faces the tip of the electronic pen. The outer diameter of the connecting part 302 is slightly larger than the size of the opening of the groove structure. During assembly, the connecting part 302 is first passed through the first through hole 101. The contact part 301 is located on the side of the pen body 10 away from the receiving cavity. The conductive component 20 is inserted into the receiving cavity of the pen body 10 from the end of the pen body 10 away from the tip, such as the pen tail end, along the second direction Y. Since the opening of the groove structure faces the tip of the electronic pen, the connecting part 302 can be inserted into the groove structure and press-fitted with the groove structure, so that the connecting part 302 is engaged with the conductive component. The orientation of the opening of the groove structure is consistent with the assembly direction of the conductive component 20 into the pen body 10, which improves the convenience of connecting the charging contact 30 and the conductive component 20.

[0029] In Embodiment 2, the connection part 302 can be engaged with the conductive part to achieve the limiting and electrical connection of the conductive part 20 to the charging contact 30. At this time, the conductive part 20 and the limiting part 303 form limiting interference in at least one direction, or they may not form limiting interference. In Embodiment 2, this is not restricted.

[0030] Understandably, by engaging the connecting part 302 with the conductive component 20, the charging contact 30 and the conductive component 20 can be fixed without additional fasteners, simplifying the assembly process and improving assembly efficiency. The engagement of the connecting part 302 and the conductive component 20 restricts their relative displacement in multiple directions, while ensuring a stable electrical connection between the charging contact 30 and the conductive component 20. In particular, the interference fit further enhances the contact tightness between the connecting part 302 and the conductive component 20, thereby improving the stability and reliability of the electrical connection and effectively preventing poor contact caused by vibration or shaking during use of the electronic pen.

[0031] Example 3 In one embodiment, along the first direction X, the limiting portion 303 in the aforementioned embodiment of this application abuts against the side of the conductive component 20 away from the contact portion 301.

[0032] Specifically, as described in Embodiment 1, after the connecting part 302 passes through the first through hole 101 and the hollow structure 201, the limiting part 303 is located on the side of the conductive component 20 away from the contact part 301. In this embodiment, the limiting part 303 also abuts against the side of the conductive component 20 away from the contact part 301, so that the limiting part 303 is limited by the hollow structure 201. At least a portion of the contact part 301 is embedded in the pen body 10, that is, at least a portion of the contact part 301 abuts against the pen body 10, so that the contact part 301 is limited by the pen body 10. In this way, both ends of the charging contact 30 along the first direction X are abutted and limited, preventing the charging contact 30 from becoming loose in the first direction.

[0033] In some embodiments, the limiting part 303 abuts against the side of the conductive member 20 away from the contact part 301, and the limiting part 303 and the contact part 301 are electrically connected, so that after the limiting part 303 abuts against the conductive member 20, the contact part 301 is electrically connected to the conductive member 20 through the limiting part 303. Specifically, a conductive connector may be embedded inside the connecting part 302. Both the contact part 301 and the limiting part 303 are made of conductive material. One end of the conductive connector is electrically connected to the contact part 301, and the other end is electrically connected to the limiting part 303. The embodiments of this application do not limit the specific electrical connection method between the limiting part 303 and the contact part 301.

[0034] In some embodiments, a recess is formed along the first direction X, which is closer to the limiting portion 303, forming a circumferential recess. The limiting portion 303 abuts against the recess. The circumferential structure allows the abutting force to be evenly distributed, reducing local stress concentration and lowering the risk of deformation of the component due to long-term stress.

[0035] Understandably, by having the limiting portion 303 of the charging contact 30 pass through the first through hole 101 and the hollow structure 201 in the connecting portion 302, it forms an abutment with the side of the conductive component 20 away from the contact portion 301. Combined with the design that the contact portion 301 is at least partially embedded in the pen body 10, the two ends of the charging contact 30 along the first direction X are respectively abutted and limited by the conductive component 20 and the pen body 10. This not only firmly fixes the position of the charging contact 30 from both sides, effectively preventing it from loosening or shifting in the first direction X, but also further enhances the stability of the connection between the connecting portion 302 and the hollow structure 201, reducing the problem of poor electrical connection caused by the shaking of the charging contact 30.

[0036] Example 4 In one embodiment, the hollow structure 201 in the aforementioned embodiment 1 of this application is a first groove, such as... Figures 2 to 4 and Figure 18 As shown, the first groove includes an opening 2011 along the second direction Y. The opening 2011 and the first groove are disposed at one end of the conductive member 20 near the tip of the electronic pen. The opening of the first groove faces the writing end of the electronic pen. The conductive member 20 and the limiting part 303 form a limiting interference in at least one direction, so that the first groove forms a mechanical limiting on the limiting part 303 in the first direction X.

[0037] In some embodiments, the first groove includes an opening 2011, through which the connecting part 302 enters the first groove. Along the second direction Y, the opening 2011 of the first groove faces the writing end of the electronic pen; it should be noted that the writing end is the pen tip. Specifically, during assembly, the connecting part 302 is first passed through the first through hole 101, and the conductive component 20 is inserted into the receiving cavity of the pen body 10 from the end of the pen body 10 away from the pen tip, such as the pen tail end, along the second direction Y. Since the opening 2011 of the first groove faces the pen tip, the connecting part 302 can be engaged in the first groove. At this time, the limiting part 303 is located on the side of the conductive component 20 away from the contact part 301, thereby achieving the connection between the charging contact 30 and the conductive component 20. The orientation of the opening 2011 of the first groove is consistent with the assembly direction of the conductive component 20 assembled into the pen body 10, improving the convenience of connecting the charging contact 30 and the conductive component 20.

[0038] Understandably, the conductive component 20 and the limiting portion 303 form a limiting interference in at least one direction, preventing the limiting portion 303 from sliding out of the first groove, thereby effectively blocking the charging contact 30. This structure eliminates the need for additional auxiliary limiting components; the dimensional relationship between the limiting portion 303 and the first groove is sufficient to restrict the movement of the charging contact 30 out of the receiving cavity in the first direction X, further enhancing the limiting stability of the charging contact 30 and preventing it from loosening or falling off due to limiting failure. It also ensures the continuous reliability of the electrical connection between the charging contact 30 and the conductive component 20.

[0039] Understandably, in some embodiments, based on the above-described embodiment four, the limiting part 303 can be cubic or cylindrical. This application embodiment does not limit its specific shape, as long as it can form a limiting interference with the first groove in at least one direction to achieve limiting. The first groove can be a circular groove or an irregularly shaped groove. This application embodiment does not limit its specific shape, as long as it can engage and abut the connecting part 302 so that the contact part 301 can be electrically connected to the conductive component 20.

[0040] Example 5 In some implementations, based on the above-described embodiment one, such as... Figure 3 As shown, a second groove 102 is formed on the side wall of the pen body 10 at the position corresponding to the first through hole 101. Its inner diameter is adapted to the outer dimensions of the contact part 301. The second groove 102 is located on the side of the pen body 10 away from the receiving cavity. The second groove 102 communicates with the receiving cavity through the first through hole 101, and the size of the first through hole 101 is smaller than the size of the second groove 102; that is, along the first direction X, the outer periphery of the first through hole 101 is smaller than the outer periphery of the second groove 102. The contact part 301 and the second groove 102 are shaped and have an interference fit. During assembly, the contact part 301 is aligned with the second groove 102 and pressure is applied, causing the contact part 301 to be tightly fitted into the second groove 102 through the interference fit, so that the contact part 301 and the pen body 10 have an interference fit. At this time, the connecting part 302 just passes through the first through hole 101 into the receiving cavity of the pen body 10. The first groove of the conductive component 20 can then be inserted to complete the assembly. After the contact part 301 is installed, its outer surface is flush with the side wall of the pen body 10, which avoids the problem of the protruding structure being easily bumped and ensures the contact area with external power supply equipment.

[0041] Understandably, by creating a second groove 102 in the pen body 10 and connecting the second groove 102 to the receiving cavity through a first through hole 101, and limiting the outer periphery of the first through hole 101 to be smaller than the outer periphery of the second groove 102, combined with the interference fit between the contact part 301 and the second groove 102, on the one hand, the second groove 102 can provide assembly positioning for the contact part 301, preventing the contact part 301 from shifting during assembly. At the same time, the interference fit can fix the contact part 301 to the pen body 10 without relying on additional glue or clips, simplifying the assembly process. On the other hand, the second groove 102 forms a circumferential wrapping constraint on the contact part 301, which can effectively limit the movement of the contact part 301 along the first direction X and in the circumferential direction, further enhancing the overall stability of the charging contact 30 and preventing the contact part 301 from loosening after long-term use, resulting in poor charging contact.

[0042] Example 6 Furthermore, in some embodiments, based on the second groove 102 formed on the side wall of the pen body 10 in the above embodiment five, such as... Figure 3 As shown, the pen body 10 has a first protrusion 103. This first protrusion 103 is located on the side of the second groove 102 along the first direction X, near the conductive component 20, and at the outer edge of the first through hole 101. The first protrusion 103 is circumferentially arranged around the first through hole 101 and has an annular structure. It extends along the first direction X away from the limiting portion 303. Along the first direction X, the height of the first protrusion 103 is not greater than the depth of the second groove 102. When the contact portion 301 is fitted into the second groove 102 by an interference fit, the side of the contact portion 301 facing the limiting portion 303 abuts tightly against the first protrusion 103, and the connecting portion 302 extends into the receiving cavity through the first through hole 101 in the middle of the first protrusion 103.

[0043] Understandably, by providing a surrounding first protrusion 103 on the outer edge of the first through hole 101 and protruding along the first direction X away from the limiting part 303, the annular protrusion can physically shield the mating gap between the first through hole 101 and the connecting part 302, preventing dust, moisture and other impurities from entering the receiving cavity through the gap, thereby improving the protection effect of the internal components.

[0044] Furthermore, in some embodiments, based on the provision of the first protrusion 103 on the pen body 10 of the above embodiment six, such as... Figure 3As shown, the pen body 10 has a second protrusion 104 extending away from the limiting portion 303. The length direction of the electronic pen is the second direction Y. Along the second direction Y, the second protrusion 104 is located in the second groove 102 and is spaced apart from the first protrusion 103. Along the first direction X, the first protrusion 103 and the second protrusion 104 have the same height and together form support for the contact portion 301. The first protrusion 103 is an annular structure surrounding the first through hole 101, and the second protrusion 104 is a structure with the same height as the first protrusion 103. In this embodiment, the shape of the second protrusion 104 is not limited, and the top surfaces of both are smoothed. When the contact portion 301 is embedded in the second groove 102, the side of it that is close to the limiting portion 303 along the first direction X simultaneously abuts against the first protrusion 103 and the second protrusion 104, forming two supports, so that the contact portion 301 remains horizontal and stable in the second groove 102, avoiding tilting or shaking caused by force on one side.

[0045] Understandably, by adding a second protrusion 104 to the second groove 102, which is located on both sides of the first protrusion 103 along the second direction Y and maintains the same height, on the one hand, the two support structures can provide more stable support for the contact part 301, preventing the contact part 301 from tilting due to long-term use or external pressure, ensuring that the outer surface of the contact part 301 remains flush with the side wall of the pen body 10, and improving the reliability of contact with external power supply equipment. On the other hand, the two protrusions can distribute the pressure on the contact part 301, reduce stress concentration when supported at a single point, reduce the risk of deformation of the contact part 301 or the second groove 102 due to excessive force, and extend the service life of the structure.

[0046] Furthermore, in some embodiments, based on the second groove 102 formed on the pen body 10 in any of the above embodiments, and on the basis that the contact portion 301 is embedded in the second groove 102 and forms an interference fit, conductive adhesive or waterproof adhesive is filled between the side of the contact portion 301 near the limiting portion 303 and the side of the second groove 102 near the limiting portion 303 for fixation. On the one hand, after the adhesive cures, it can form a tight bond with the contact portion 301 and the second groove 102, further enhancing the connection strength between the two and preventing the contact portion 301 from loosening due to external forces such as vibration and pressing during long-term use. On the other hand, the adhesive can fill the tiny gap between the contact portion 301 and the second groove 102, forming a sealed structure, effectively preventing external moisture, dust and other impurities from seeping into the pen body 10 cavity through the gap, further improving the waterproof and dustproof capabilities of the electronic pen and ensuring the stable operation of internal components.

[0047] Example 7 In some implementations, based on the above-described embodiment four, such as... Figure 4 , Figure 6 and Figure 7As shown, the electronic pen also includes a fixing bracket 40, which is made of insulating material and conforms to the internal contour of the pen body 10's receiving cavity. A third groove 401 is formed on the side of the fixing bracket 40 facing the conductive component 20. The groove shape and size of the third groove 401 match the main structure of the conductive component 20. At least a portion of the conductive component 20 is accommodated in the third groove 401, and the groove wall of the third groove 401 fits against the side wall of the conductive component 20, preventing the conductive component 20 from moving freely relative to the fixing bracket 40. The fixing bracket 40 can be connected to the inner wall of the pen body 10's receiving cavity via a snap-fit ​​structure, ensuring overall positional stability and providing a reliable mounting reference for the conductive component 20.

[0048] Understandably, by setting a fixing bracket 40 with a third groove 401 and embedding the conductive component 20 at least partially into the groove, on the one hand, the third groove 401 can provide positioning and circumferential constraints for the conductive component 20, effectively limiting the movement of the conductive component 20 along the first direction X, the second direction Y, and the third direction Z, avoiding displacement of the conductive component 20 due to shaking or dropping of the electronic pen, thereby ensuring the stability of its electrical connection with the charging contact 30 and the reliability of its connection with the motherboard 60. At the same time, the tight combination of plastic and metal improves the overall structural strength, which can better resist external impacts such as dropping and vibration of the electronic pen. Any two of the first direction X, the second direction Y, and the third direction Z are orthogonal. On the other hand, the fixing bracket 40 can physically isolate the conductive component 20 from other components such as the battery 50 and the motherboard 60 in the receiving cavity, reducing interference between different components. At the same time, the insulating material of the fixing bracket 40 can reduce the risk of short circuit between the conductive component 20 and other metal components.

[0049] In some embodiments, the fixing bracket 40 and the conductive component 20 can be an integrated structure. The main body of the fixing bracket 40 is made of insulating plastic material, and the conductive component 20 is formed into the fixing bracket 40 by an insert process. Specifically, during preparation, the conductive component 20 is positioned and fixed in the cavity of the injection mold, and then the molten insulating plastic material is injected into the mold cavity. After the plastic material cools and solidifies, an integrated part is formed.

[0050] In some implementations, based on the above-described embodiment seven, such as Figures 6 to 12As shown, along the second direction Y, one end of the fixing bracket 40 has a third groove 401 for accommodating the conductive component 20, and the other end has a fifth groove 402 adapted to the shape of the battery 50. The battery 50 is disposed in the fifth groove 402. Specifically, the depth of the fifth groove 402 can be slightly greater than the thickness of the battery 50, and the groove wall can be provided with elastic buckles for fixing the battery 50. Along the first direction X, a mounting position for the main board 60 is reserved on one side of the fixing bracket 40 adjacent to the third groove 401. The main board 60 can be fixed to the fixing bracket 40 with screws. This embodiment does not limit the specific fixing method. The other side of the fixing bracket 40 is the third groove 401 and a partial extension structure of the conductive component 20.

[0051] Understandably, by setting a fifth groove 402 on the fixed bracket 40 and placing the battery 50 therein, while the motherboard 60 and the third groove 401 are respectively located on both sides of the fixed bracket 40, on the one hand, the fixed bracket 40 can serve as the structural hub inside the electronic pen, realizing the integration of conductive components 20, battery 50, and motherboard 60, greatly improving the utilization rate of the cavity space and adapting to the miniaturization design requirements of the electronic pen. On the other hand, each core component forms a relatively independent installation area through the fixed bracket 40, which can reduce vibration interference and signal interference between components. At the same time, the insulating material of the fixed bracket 40 can isolate the conductive components 20 from unnecessary contact with the motherboard 60 and battery 50, reducing the risk of short circuit.

[0052] Example 8 In some embodiments, based on the above embodiment seven which includes a motherboard 60 and a battery 50, such as... Figures 11 to 13 As shown, the conductive component 20 includes a first connecting portion 202, a first extending portion 203, a second extending portion 204, and a second connecting portion 205. The electronic pen also has a third direction Z, and any two of the first direction X, the second direction Y, and the third direction Z are orthogonal. One end of the first connecting portion 202 is connected to one end of the first extending portion 203, and the first connecting portion 202 extends along the third direction Z. The first extending portion 203 extends along the second direction Y, and the other end of the first extending portion 203 is connected to the second extending portion 204. The second extending portion 204 extends along the first direction X, and the other end of the second extending portion 204 is connected to the second connecting portion 205, and the second connecting portion 205 extends along the third direction Z. A hollow structure 201 is formed on the second connecting portion 205.

[0053] Specifically, the conductive component 20 can be divided into a first connecting portion 202, a first extension portion 203, a second extension portion 204, and a second connecting portion 205. The thickness direction of the electronic pen can be a third direction Z. The first connecting portion 202 extends along the third direction Z and is electrically connected to the motherboard 60. The first extension portion 203 is formed by bending the end of the first connecting portion 202 and extends along the second direction Y. The second extension portion 204 is connected to the end of the first extension portion 203 along the third direction Z. The second extension portion 204 extends along the first direction X toward the charging contact 30. The second connecting portion 205 is formed by bending the end of the second extension portion 204 and extending along the third direction Z. The second extension portion 204 is attached to the side wall of the fixing bracket 40.

[0054] Understandably, by designing the conductive component 20 as a multi-segmented extension structure and bending it sequentially in three directions, on the one hand, the three-dimensional layout can make full use of the three-dimensional space inside the electronic pen, avoiding the installation areas of components such as the battery 50 and the motherboard 60, and achieving the connection of the conductive component 20 from the motherboard 60 to the charging contact 30 within the limited cavity, significantly improving space utilization. On the other hand, the extensions extend in a functional direction, which can control the length and direction of the conductive path, reduce unnecessary material consumption, and at the same time, the bending structure absorbs the stress when the electronic pen is dropped or vibrated, preventing the conductive component 20 from breaking and improving structural durability.

[0055] In some embodiments, based on Embodiment 8, such as Figures 6 to 10 As shown, along the third direction Z, the third groove 401 has a second through hole 4011, which penetrates the third groove 401 along the third direction Z. The first connecting part 202 passes through the second through hole 4011 and is connected to the first extension part 203. The first extension part 203 is embedded in the third groove 401. The third groove 401 extends along the second direction Y. Along the second direction Y, a notch 4012 is provided on the side of the third groove 401 near the charging contact 30. The notch 4012 extends along the first direction X, and the second extension part 204 is accommodated in the notch 4012.

[0056] Specifically, the third groove 401 of the fixing bracket 40 extends along the second direction Y, and the groove depth is adapted to the thickness of the first extension 203. The third groove 401 has a second through hole 4011 adapted to the first connecting part 202 of the conductive component 20. The second through hole 4011 penetrates the third groove 401 along the third direction Z. The diameter of the through hole is slightly larger than the width of the first connecting part 202 to ensure that the first connecting part 202 can be smoothly inserted without significant shaking. Along the second direction Y, a notch 4012 extending in the first direction X is formed on the side of the third groove 401 near the charging contact 30. The width and height of the notch 4012 are adapted to the width and thickness of the second extension 204, respectively. During assembly, the first connecting part 202 of the conductive component 20 passes through the second through hole 4011 from the side of the fixed bracket 40 away from the third groove 401, extends to the outside of the fixed bracket 40 and connects with the main board 60. The first extension part 203 is embedded in the third groove 401, and the groove wall and the side wall of the extension part are tightly fitted. The second extension part 204 extends out through the notch 4012 of the third groove 401 and extends along the first direction X to a position close to the side wall of the pen body 10. The second extension part 204 is connected to the second connecting part 205, and finally the second connecting part 205 is aligned with the first through hole 101.

[0057] Understandably, by opening a second through hole 4011 in the third groove 401 for the first connecting part 202 to pass through, and opening a notch 4012 on the side of the groove for the second extension part 204 to be embedded, on the one hand, the second through hole 4011 and the notch 4012 can respectively position the first connecting part 202 and the second extension part 204 of the conductive component 20. Combined with the fitting of the first extension part 203 and the third groove 401, the conductive component 20 is fully constrained in three dimensions, preventing the conductive component 20 from shifting due to vibration or drop of the electronic pen, and ensuring the stability of its connection with the motherboard 60 and the charging contact 30. On the other hand, this groove structure with holes and notches 4012 can guide the conductive component 20 to be assembled along a preset path, and can quickly complete the embedding without additional positioning fixtures, greatly improving assembly efficiency. Meanwhile, the close fit between each extension and the groove, through hole, and notch 4012 can reduce the suspended area of ​​the conductive component 20, enhance its structural rigidity, avoid deformation after long-term use, further extend its service life, and take into account both positioning accuracy and structural reliability.

[0058] Example 9 In some implementations, based on the above-described embodiment eight, such as Figure 16 and Figure 17As shown, the second connecting portion 205 in Embodiment 8 includes a first abutting portion 2051, a slotted portion 2052, and a second abutting portion 2053. A hollow structure 201 is formed on the slotted portion 2052. Along the third direction Z, one end of the first abutting portion 2051 is connected to one end of the second extension portion 204, and the other end is connected to the slotted portion 2052. The other end of the slotted portion 2052 is connected to one end of the second abutting portion 2053. Along the second direction Y, the first abutting portion 2051 and the second abutting portion 2053 abut against the fixed bracket 40. The slotted portion 2052 and the fixed bracket 40 form a receiving space, and the limiting portion 303 is received in the receiving space.

[0059] Specifically, the second connecting portion 205 of the conductive component 20 consists of a first abutting portion 2051, a slotted portion 2052, and a second abutting portion 2053, which are sequentially connected along the third direction Z. Preferably, the conductive component 20 can be integrally stamped. Along the second direction Y, the first abutting portion 2051 and the second abutting portion 2053 abut against the fixed bracket 40, and the slotted portion 2052 is recessed to the side away from the fixed bracket 40. One end of the first abutting portion 2051 is connected to the second extension portion 204, and the other end is connected to the slotted portion 2052. The hollow structure is opened at the center of the recessed area, with the slot facing the pen tip. The second abutting portion 2053 and the first abutting portion 2051 are symmetrically arranged along the slotted portion 2052. One end of the second abutting portion 2053 is connected to the slotted portion 2052, and the other end extends to the edge of the fixed bracket 40. When assembled along the second direction Y, as follows... Figure 17 As shown, the first abutting part 2051 and the second abutting part 2053 abut against the surface of the fixed bracket 40 near the charging contact 30, respectively. The slotted part 2052 is recessed to the side away from the fixed bracket 40 to form a receiving space. The limiting part 303 of the charging contact 30 passes through the hollow structure 201 and is placed in the receiving space.

[0060] Understandably, by dividing the second connecting portion 205 into a first abutting portion 2051, a slotted portion 2052, and a second abutting portion 2053, and making the slotted portion 2052 recessed towards the side closer to the first through hole 101, on the one hand, this arrangement provides a accommodating space for the limiting portion 303, preventing the limiting portion 303 from protruding and interfering with other components. Simultaneously, the abutting of the first abutting portion 2051, the second abutting portion 2053, and the fixing bracket 40 restricts the shaking of the second connecting portion 205 itself, indirectly improving the assembly stability of the charging contact 30. On the other hand, the symmetrical abutting design of the first abutting portion 2051 and the second abutting portion 2053 disperses the force on the slotted portion 2052, preventing deformation of the slotted portion 2052 due to compression by the limiting portion 303, ensuring the fit between the hollow structure 201 and the connecting portion 302, thereby maintaining a stable electrical connection. In addition, the enveloping storage of the limiting part 303 by the accommodating space can also reduce the impact of external vibrations on the limiting part 303.

[0061] In some implementations, based on the above-described embodiment nine, such as Figures 13 to 15 As shown, along the second direction Y, the hollow structure 201 in Embodiment 9 is provided at the end of the slotted portion 2052 away from the first connecting portion 202, and the end of the slotted portion 2052 near the first connecting portion 202 is provided with a fourth groove 20521; along the second direction Y, the fixed bracket 40 is provided with a protrusion 403 on the side near the charging contact 30, and the protrusion 403 is provided in the fourth groove 20521.

[0062] Specifically, the slotted portion 2052 of the conductive component 20 is elongated along the second direction Y. At the end furthest from the main board 60, a hollow structure 201 for engaging the charging contact 30 is provided. At the end closer to the main board 60, a fourth groove 20521 is provided. The opening of the fourth groove 20521 faces away from the pen tip, and the groove shape of the fourth groove 20521 matches the protrusion 403 of the fixing bracket 40. On the side of the fixing bracket 40 near the charging contact 30, a rectangular protrusion 403 is provided corresponding to the position of the fourth groove 20521. During assembly, the battery 50 is first fixed in the fifth groove 402, and then the first connecting part 202 of the conductive component 20 is passed through the second through hole 4011. The main board 60 is fixed on one side of the third groove 401, the first extension 203 is embedded in the third groove 401, the second extension 204 is embedded in the notch 4012, and the protrusion 403 is inserted into the fourth groove 20521 so that the conductive component 20 is assembled with the fixed bracket 40. Then, the fixed bracket with the assembled conductive component 20 is inserted into the pen body 10 along the second direction Y from the side away from the pen tip.

[0063] In some embodiments, the inner wall of the pen body 10 receiving cavity may be provided with a guide rail, and the fixing bracket 40 may be provided with a positioning groove that cooperates with the guide rail, so that the fixing bracket 40 can be positioned with the pen body 10, and the charging contact 30 can be connected to the conductive component 20.

[0064] Understandably, by creating a fourth groove 20521 at the end of the slotted portion 2052 near the motherboard 60, and embedding the protrusion 403 of the fixing bracket 40 therein, on the one hand, the cooperation between the protrusion 403 and the fourth groove 20521 can limit the slotted portion 2052 in the second direction Y, preventing the conductive component 20 from shifting along the length direction due to vibration or assembly errors, ensuring that the relative positions of the hollow structure 201, the charging contact 30, and the first through hole 101 of the pen body 10 are always accurate, and ensuring the stability of the electrical connection. On the other hand, this concave-convex cooperation structure can further enhance the bonding strength between the second connecting portion 205 and the fixing bracket 40, disperse the force on the slotted portion 2052, prevent it from deforming due to the compression of the limiting portion 303 during long-term use, and greatly improve the overall assembly firmness of the conductive component 20.

[0065] Understandably, the conductive component 20, the first through hole 101, and the charging contact 30 each include two. One charging contact 30 and the conductive component 20 form a positive charging circuit, and the other charging contact 30 and the conductive component 20 form a negative charging circuit. The first through hole 101 is correspondingly arranged with the charging contact 30. Along the first direction X, the two first through holes 101 are symmetrically arranged along the central axis of the electronic pen.
