[0059] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0060] The embodiments of this application are described below with reference to Figures 1 to 19.

[0061] According to embodiments of this application, in one aspect, an electronic pen is provided, comprising:

[0062] The pen body has a nib and a first receiving cavity;

[0063] The battery module is detachably disposed within the first receiving cavity;

[0064] A connecting component is provided between the battery module and the pen body; the connecting component is a first connecting component or a second connecting component.

[0065] The first connection component includes:

[0066] A circuit board is disposed in the first receiving cavity. The side of the circuit board facing the battery module is provided with a first electrical connection part and a second electrical connection part. The first electrical connection part is located on the axis of the first receiving cavity, and the second electrical connection part is coaxially and spaced apart from the outside of the first electrical connection part. The second electrical connection part is annular.

[0067] The battery module includes a battery and two electrical connectors. The first ends of the two electrical connectors are electrically connected to the positive and negative terminals of the battery, respectively. The second ends of the two electrical connectors are electrically connected to the first electrical connection portion and the second electrical connection portion, respectively, when the battery module is installed.

[0068] The second connection component includes:

[0069] The first slot is located on the inner wall of the pen body;

[0070] A telescopic member is provided on the battery module. The telescopic member is telescopically arranged in a direction intersecting the axis of the first receiving cavity. The telescopic member has an extended position and a retracted position. In the extended position, the telescopic member is engaged with the first slot. In the retracted position, the telescopic member is disengaged from the first slot.

[0071] The electronic pen provided in this application embodiment can effectively improve the convenience of battery module replacement by setting a first connecting component or a second connecting component.

[0072] When the first connecting component is used, the first electrical connection part on the circuit board is located at the axis, and the second electrical connection part is a coaxially arranged annular ring, together forming an axisymmetric contact interface. This design allows the battery module to be inserted into the first receiving cavity of the pen body without the need for specific circumferential angle alignment. Even if it rotates around the axis, the two electrical connections on it can always accurately contact the first and second electrical connection parts and conduct the circuit, achieving a "foolproof" effect, simplifying the installation steps, and making the replacement operation more intuitive and quick.

[0073] When the second connecting component is used, convenient replacement is achieved through the mechanical engagement of the telescopic component and the first slot. During installation, the telescopic component automatically retracts under pressure from the inner wall of the pen body and automatically pops out to engage with the first slot when it reaches the predetermined position, thus securing it. During disassembly, only axial tension needs to be applied, and the telescopic component will retract under pressure and disengage from the slot. This "one-click" plug-in / plug-out design eliminates complicated twisting or unlocking steps and greatly optimizes the battery module replacement process.

[0074] Therefore, whether through the electrical connection foolproof design of the first connecting component or the mechanical snap-fit ​​quick-release design of the second connecting component, the effect of simplifying operation and improving the convenience of battery module replacement can be achieved.

[0075] To facilitate better explanation and understanding, the following describes the solutions of the embodiments of this application through two specific electronic pen structures.

[0076] According to an embodiment of this application, an electronic pen is provided, as shown in Figures 1 and 2. The electronic pen includes a pen body 1, a fastener, a first circuit board 3, and a first battery module 4. The pen body 1 has a pen tip and a first receiving cavity 10, and the fastener is connected to the end of the pen body 1 away from the pen tip. The first circuit board 3 and the first battery module 4 are both located within the first receiving cavity 10.

[0077] Specifically, the first circuit board 3 has a first electrical connection portion 32 and a second electrical connection portion 33 on the side facing the first pen cap 2. The first electrical connection portion 32 is located on the axis of the first receiving cavity 10, and the second electrical connection portion 33 is coaxially and spaced apart on the outside of the first electrical connection portion 32 so as to be mutually insulated from the first electrical connection portion, and the second electrical connection portion 33 is annular.

[0078] It should be noted that both the first electrical connection portion 32 and the second electrical connection portion 33 extend around the axis of the first receiving cavity 10. Furthermore, this application does not specifically limit the shape and structure of the first electrical connection portion 32, as long as it can abut against the first electrical connector 42 to achieve the electrical connection function. For example, the first electrical connection portion 32 can be circular, annular, rectangular, etc.

[0079] Furthermore, the first battery module 4 is located between the first circuit board 3 and the fastener. The first battery module 4 includes a first battery 41 and two first electrical connectors 42, which are respectively disposed corresponding to the first electrical connection portion 32 and the second electrical connection portion 33. The first ends of the two first electrical connectors 42 are electrically connected to the positive and negative terminals of the first battery 41, respectively, and the second ends of the two first electrical connectors 42 are electrically connected to the first electrical connection portion 32 and the second electrical connection portion 33, respectively.

[0080] In this embodiment, when the pen body 1 is connected to the fastener, the two first electrical connectors 42 of the first battery module 4 are electrically connected to the first electrical connection portion 32 and the second electrical connection portion 33 of the first circuit board 3, respectively, forming a circuit connection. The first electrical connection portion 32 located on the axis of the first receiving cavity 10 and the annular second electrical connection portion 33 form a 360° foolproof design. When the first battery module 4 is installed into the first receiving cavity 10, even if it rotates around the axis of the pen body 1, the two first electrical connectors 42 can still correspond to the positions of the first electrical connection portion and the second electrical connection portion, which facilitates the installation of the first battery module 4 and improves the convenience of replacing the first battery module 4.

[0081] Specifically, in some embodiments, as shown in FIG6, the first circuit board 3 includes a board body 31, a first electrical connection portion 32 and a second electrical connection portion 33 are both disposed on the board body 31, and the board body 31 has an insulating portion 34, which is coaxially disposed between the first electrical connection portion 32 and the second electrical connection portion 33 so that the first electrical connection portion 32 and the second electrical connection portion 33 are mutually insulated.

[0082] For example, the board 31 has a copper leakage point and a copper leakage ring. The copper leakage point is located in the middle of the board 31 and forms a first electrical connection portion 32. The copper leakage ring is located around the copper leakage point and forms a second electrical connection portion 33.

[0083] Understandably, this application does not specifically limit the shape and structure of the first circuit board 3, as long as the first electrical connection portion 32 is located on the axis of the first receiving cavity 10. For example, the first circuit board 3 can be constructed as a circular plate structure, a rectangular plate structure, etc.

[0084] Furthermore, this application does not specifically limit the shape and structure of the first battery module 4, as long as it can be installed in the first receiving cavity 10 and form a circuit connection with the first circuit board 3. For example, the first battery module 4 can be constructed as a cylindrical structure, a cubic structure, etc. Preferably, the shape and structure of the first battery module 4 are adapted to the first receiving cavity 10 to ensure the stability of the installation of the first battery module 4 and avoid shaking.

[0085] In some embodiments, both the first receiving cavity 10 and the first battery module 4 are cylindrical and coaxially arranged. The two first electrical connectors 42 of the first battery module 4 are a first electrical connector and a second first electrical connector, respectively. The first electrical connector is located on the axis of the first battery module 4, that is, on the axis of the first receiving cavity 10, and is arranged opposite to the first electrical connection portion. The second first electrical connector is radially spaced from the first electrical connector in the first receiving cavity 10, and the distance between the second first electrical connector and the first electrical connector is equal to the distance between the first electrical connection portion 32 and the second electrical connection portion 33, so that the second first electrical connector is arranged opposite to the second electrical connection portion 33.

[0086] Furthermore, in some embodiments, as shown in Figures 2 and 3, the first battery module 4 further includes a housing 43. Two connection holes 4321 are provided at the end of the housing 43 facing the first circuit board 3, connecting the interior and exterior of the housing 43. The first battery 41 is disposed inside the housing 43, and two first electrical connectors 42 are respectively fixedly connected to the two connection holes 4321, with at least a portion of the second end of each first electrical connector 42 protruding from the end face of the housing 43 facing the first circuit board 3. This arrangement ensures that the two first electrical connectors 42 are fixed to the housing 43 through the two connection holes 4321, guaranteeing the stability of the relative positions of the two first electrical connectors 42.

[0087] For example, the first electrical connector 42 may be glued, snapped, or interference-fitted into the connector hole 4321.

[0088] Specifically, in some embodiments, as shown in FIG5, the outer casing 43 includes a housing 431 and a cover 432, the cover 432 being connected to one end of the housing 431, and a connection hole 4321 being provided on the cover 432. The outer casing 43 being configured as a housing 431 and a cover 432 facilitates the installation of the first battery 41 and the first electrical connector 42, improving the ease of assembly of the first battery module 4.

[0089] For example, the housing 431 and the cover 432 can be fixedly connected or detachably connected. Understandably, in this embodiment, the cover 432 can be made of insulating material, or partially provided with insulating material, to ensure that the two first electrical connectors 42 are mutually insulated.

[0090] In some embodiments, as shown in FIG3, the first battery module 4 further includes a first buffer member 44, which is fixedly connected to the outside of the housing 43 and located at the end of the housing 43 near the fastener. Understandably, when the fastener is connected to the pen body 1, the first buffer member 44 abuts against the housing 43 and the fastener. The first buffer member 44 ensures that the first battery module 4 does not wobble after being installed in the first receiving cavity 10, guaranteeing the reliability of the electrical connection between the first battery module 4 and the first circuit board 3. Exemplarily, the first buffer member 44 can be foam or other flexible materials. Exemplarily, the first buffer member 44 can be adhered to the housing 43.

[0091] In some embodiments, the outer casing 43 includes the cover 432 and the housing 431 described above, and the first buffer 44 is fixedly connected to the side of the housing 431 away from the cover 432.

[0092] Further, in some embodiments, as shown in FIG4, the first electrical connector 42 includes a tube body 421, a head 422, and a first elastic part 423. The head 422 is slidably connected within the tube body 421, and the first elastic part 423 is connected between the tube body 421 and the head 422. The tube body 421 forms a first end, and the head 422 forms a second end. The heads 422 of the two first electrical connectors 42 respectively abut against the first electrical connection part 32 and the second electrical connection part 33 to achieve electrical connection with the first electrical connection part 32 and the second electrical connection part 33. In this embodiment, the first elastic part 423 can support the head 422 to strengthen the abutment between the head 422 and the first electrical connection part 32 or the second electrical connection part 33, ensuring the reliability of the electrical connection. The two first electrical connectors 42, arranged in this way, can achieve electrical connection with the first electrical connector 32 and the second electrical connector 33 by abutting against them, thereby further improving the convenience of replacing the first battery module 4.

[0093] In some embodiments not shown, the first electrical connector 42 may also be constructed as a solid metal conductor, with the two ends of the metal conductor forming a first end and a second end, respectively.

[0094] Furthermore, this application does not impose specific limitations on the electrical connection method between the first end of the first electrical connector 42 and the positive or negative terminal of the first battery 41, as long as the circuit conduction function can be achieved.

[0095] Furthermore, in some embodiments, the electronic pen also includes a pen refill holder 5, which is disposed within the first receiving cavity 10 and is used to fix the pen refill (not shown in the figure) within the first receiving cavity 10. The pen refill holder 5 is located at the end of the first battery module 4 away from the fastener, and the first circuit board 3 is disposed on the pen refill holder 5. In this embodiment, the first circuit board 3 is integrated on the pen refill holder 5, which can be installed synchronously with the pen refill, improving the convenience of electronic pen assembly.

[0096] The connection between the first circuit board 3 and the pen refill holder 5 can be either fixed or detachable. For example, the first circuit board 3 can be adhered to the pen refill holder 5 by applying adhesive or using backing adhesive, or the first circuit board 3 can be snapped into the pen refill holder 5.

[0097] Specifically, in some embodiments, as shown in Figures 7 and 8, the pen refill holder 5 has a first groove 51 on the side facing the first battery module 4, and the first circuit board 3 is embedded in the first groove 51. The first groove 51 can position the first circuit board 3 so that when the first circuit board 3 is installed on the pen refill holder 5, the first electrical connection part 32 can be located on the axis of the first receiving cavity 10.

[0098] In some embodiments not shown, the end face of the pen refill holder 5 facing the first battery module 4 can also be set as a plane, and the first circuit board 3 is fixedly connected to the end face, such as by bonding or snapping.

[0099] Understandably, the pen refill holder 5, the first circuit board 3, the first battery module 4, and the fasteners are arranged sequentially along the axial direction of the first receiving cavity 10. Preferably, the pen refill holder 5, the first circuit board 3, the first battery module 4, and the fasteners are arranged coaxially.

[0100] Furthermore, this application does not specifically limit the shape and structure of the fastener, as long as it can function to fix the first battery module 4 within the first receiving cavity. For example, the fastener can be the first pen cap 2, or it can be other components with a fixing function.

[0101] In some embodiments, as shown in FIG3, the fastener includes a first pen cap 2 and a reinforcing member 6. The reinforcing member 6 is annular, and at least a portion of its structure is located within the first receiving cavity 10 and is fixedly connected to the pen body 1. The first pen cap 2 and the reinforcing member 6 are detachably connected to facilitate opening or closing the first receiving cavity 10. In this embodiment, the cooperative arrangement of the reinforcing member 6 and the pen body 1 improves the structural strength of the pen body 1 and reduces the risk of cracking. Furthermore, the detachable connection between the first pen cap 2 and the reinforcing member 6 facilitates the installation or removal of the first battery module 4 from the first receiving cavity.

[0102] For example, the reinforcing member 6 can be connected to the pen body 1 by bonding, snap-fitting, interference fit, etc., as long as the reinforcing member 6 can be fixed to the pen body 1.

[0103] For example, the connection between the reinforcing member 6 and the first pen cap 2 can be a threaded connection, a snap-fit ​​connection, or any other means that can enable a detachable connection between the two.

At least a portion of the main structure passes through the first receiving cavity 10 along a first direction X, and the telescopic member 71 is telescopically disposed within the main structure along a second direction Y. The telescopic member 71 has an extended position and a retracted position. In the extended position, at least a portion of the telescopic member 71 protrudes from the main structure and engages with the first slot 121; in the retracted position, the telescopic member 71 disengages from the first slot 121.

[0110] In this context, the first direction X intersects with the second direction Y. In some cases, the first direction X is perpendicular to the second direction Y. The first direction X can be the length direction of the pen body 1, and the second direction Y can be any direction perpendicular to the length direction of the pen body 1. In some cases, the second direction Y specifically refers to the radial direction of the pen body 1.

[0112] In this embodiment, when the second battery module 7 is installed into the first receiving cavity 10, the telescopic member 71 is compressed by the inner wall of the pen body 1 and retracts. After installation, the telescopic member 71 extends and engages with the first slot 121. When removing the second battery module 7, the telescopic member 71 is pulled and retracted again by the inner wall of the pen body 1 and disengages from the first slot 121. The second battery module 7 is easy to install and remove, which greatly improves the convenience of replacing the second battery module 7.

[0113] More specifically, in some embodiments, the telescopic member 71 includes an elastic portion 711 and at least one ball head 712, with the ball head 712 connected to at least one end of the elastic portion 711. In the extended position, at least a portion of the structure of the ball head 712 protrudes from the main structure and engages with the first slot 121. In this embodiment, the end of the telescopic member 71 uses a ball head 712, so that when the second battery module 7 is pulled outward, the spherical outer contour of the ball head 712 can interact with the inner wall of the first slot 121, compressing the elastic portion 711 and facilitating the disassembly of the second battery module 7.

[0114] Understandably, when the telescopic member 71 is in the retracted position, the elastic part 711 is in a compressed state; when the telescopic member 71 is in the extended position, the elastic part 711 can be in a natural state or in a compressed state. For example, the elastic part 711 can be a spring, and the ball head 712 can be a steel ball.

[0115] In some embodiments, as shown in Figures 13 and 14, the telescopic member 71 is provided with two ball heads 712, which are respectively connected to the two ends of the elastic part 711. Correspondingly, the inner wall of the pen body 1 is provided with two first slots 121, which are symmetrically arranged along the central axis of the pen body 1. When the telescopic member 71 is in the extended position, the two ball heads 712 engage with the two first slots 121 respectively, thus improving the reliability of the installation. Understandably, the central axis of the pen body 1 extends along the first direction X.

[0116] In some embodiments not shown, the telescopic member 71 may also be provided with a ball head 712, and correspondingly, the inner wall of the pen body 1 is provided with a first slot 121.

[0118] The telescopic component 71 is telescopically disposed within the first connecting hole 721 and the second connecting hole 731. The diameter of the first connecting hole 721 is smaller than the maximum size of the ball head 712, and the diameter of the second connecting hole 731 is larger than the maximum size of the ball head 712. During assembly, the telescopic component 71 is installed into the second connecting hole 731, and then the first bracket 73 is installed into the tube body 72. The ball head 712 can extend out of the tube body 72 through the first connecting hole 721 without detaching from the tube body 72. In this embodiment, the diameter of the first connecting hole 721 is smaller than the maximum size of the ball head 712 to prevent the telescopic component 71 from detaching from the tube body 72 and the first bracket 73, ensuring the integrity of the second battery module 7; the diameter of the second connecting hole 731 is larger than the maximum size of the ball head 712 to facilitate the installation of the telescopic component 71 and improve the ease of assembly.

[0119] In some embodiments, the telescopic member 71 includes an elastic portion 711 and two ball heads 712, which are respectively connected to opposite ends of the elastic portion 711. Correspondingly, the inner wall of the tube body 72 is provided with two first connecting holes 721, which are symmetrically arranged along the central axis of the tube body 72; the second connecting hole 731 of the first bracket 73 is provided through the tube body 72 along the second direction Y, and along the second direction Y, the second connecting hole 731 is opposite to the two first connecting holes 721 on the tube body 72. Understandably, the central axis of the tube body 72 also extends along the first direction X.

[0120] To facilitate the fixing of the relative positions of the first bracket 73 and the tube body 72, the first bracket 73 is connected to the tube body 72. For example, the first bracket 73 and the tube body 72 can be fixedly connected, such as by bonding or interference fit; for example, the first bracket 73 and the tube body 72 can also be detachably connected, such as by threaded connection or snap-fit.

[0125] For example, the reinforcing part 12 specifically includes a large-diameter section and a small-diameter section. The outer diameter of the small-diameter section is approximately the same as the inner diameter of the pen body 11. The small-diameter section passes through the pen body 11 and is fixedly connected to the pen body 11. The outer diameter of the large-diameter section is approximately the same as the outer diameter of the pen body 11 to ensure the aesthetics of the pen body 1.
