[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] The following is combined Figures 1-11 The following describes embodiments of the present invention.

[0038] According to an embodiment of the present invention, an electronic pen is provided, such as... Figures 1-6 As shown, the electronic pen includes a pen body 1 and a battery module 2 mounted on the pen body 1. The battery module 2 is used to supply power to the electronic pen.

[0039] Specifically, the pen body 1 has a first receiving cavity 10, and the inner wall of the pen body 1 has a first slot 121. The battery module 2 includes a main structure and a telescopic member 21. At least a portion of the main structure passes through the first receiving cavity 10 along a first direction X, and the telescopic member 21 is telescopically disposed within the main structure along a second direction Y. The telescopic member 21 has an extended position and a retracted position. In the extended position, at least a portion of the telescopic member 21 protrudes from the main structure and engages with the first slot 121; in the retracted position, the telescopic member 21 disengages from the first slot 121.

[0040] 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.

[0041] Understandably, when the battery module 2 is installed into the first receiving cavity 10, the telescopic member 21 is also located in the first receiving cavity 10 and corresponds to the position of the first slot 121 so as to engage with the first slot 121.

[0042] In this embodiment, when the battery module 2 is installed into the first receiving cavity 10, the telescopic member 21 is compressed by the inner wall of the pen body 1 and retracts. After installation, the telescopic member 21 extends and engages with the first slot 121. When removing the battery module 2, the battery module 2 is pulled, and the telescopic member 21 is compressed by the inner wall of the pen body 1 and retracts again, disengaging from the first slot 121. The battery module 2 is easy to install and remove, greatly improving the convenience of replacing the battery module 2.

[0043] More specifically, in some embodiments, the telescopic member 21 includes an elastic portion 211 and at least one ball head 212, with the ball head 212 connected to at least one end of the elastic portion 211. In the extended position, at least a portion of the structure of the ball head 212 protrudes from the main structure and engages with the first slot 121. In this embodiment, the end of the telescopic member 21 uses a ball head 212. When the battery module 2 is pulled outward, the spherical outer contour of the ball head 212 can interact with the inner wall of the first slot 121, compressing the elastic portion 211 and facilitating the disassembly of the battery module 2.

[0044] Understandably, when the telescopic member 21 is in the retracted position, the elastic part 211 is in a compressed state; when the telescopic member 21 is in the extended position, the elastic part 211 can be in a natural state or in a compressed state. For example, the elastic part 211 can be a spring, and the ball head 212 can be a steel ball.

[0045] In some embodiments, such as Figure 5 and Figure 6As shown, the telescopic member 21 is provided with two ball heads 212, which are respectively connected to the two ends of the elastic part 211. 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 21 is in the extended position, the two ball heads 212 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.

[0046] In some embodiments not shown, the telescopic member 21 may also be provided with a ball head 212, and correspondingly, the inner wall of the pen body 1 is provided with a first slot 121.

[0047] Furthermore, in some embodiments, such as Figures 7-9 As shown, the main structure includes a tube 22 and a first support 23. At least a portion of the tube 22 extends through the first receiving cavity 10 along the first direction X, and a first connecting hole 221 is provided on the inner wall of the tube 22. The first support 23 extends through the tube 22 along the first direction X and is connected to the tube 22. The first support 23 is provided with a second connecting hole 231, which extends along the second direction Y and is positioned opposite to the first connecting hole 221.

[0048] The telescopic component 21 is telescopically disposed within the first connecting hole 221 and the second connecting hole 231. The diameter of the first connecting hole 221 is smaller than the maximum size of the ball head 212, and the diameter of the second connecting hole 231 is larger than the maximum size of the ball head 212. During assembly, the telescopic component 21 is installed into the second connecting hole 231, and then the first bracket 23 is installed into the tube body 22. The ball head 212 can extend out of the tube body 22 through the first connecting hole 221 without detaching from the tube body 22. In this embodiment, the diameter of the first connecting hole 221 is smaller than the maximum size of the ball head 212 to prevent the telescopic component 21 from detaching from the tube body 22 and the first bracket 23, ensuring the integrity of the battery module 2; the diameter of the second connecting hole 231 is larger than the maximum size of the ball head 212 to facilitate the installation of the telescopic component 21 and improve the ease of assembly.

[0049] In some embodiments, the telescopic member 21 includes an elastic portion 211 and two ball heads 212, which are respectively connected to opposite ends of the elastic portion 211. Correspondingly, the inner wall of the tube body 22 is provided with two first connecting holes 221, which are symmetrically arranged along the central axis of the tube body 22; the second connecting hole 231 of the first bracket 23 is provided through the tube body 22 along the second direction Y, and along the second direction Y, the second connecting hole 231 is opposite to the two first connecting holes 221 on the tube body 22. Understandably, the central axis of the tube body 22 also extends along the first direction X.

[0050] To facilitate the fixing of the relative positions of the first bracket 23 and the tube body 22, the first bracket 23 is connected to the tube body 22. For example, the first bracket 23 and the tube body 22 can be fixedly connected, such as by bonding or interference fit; for example, the first bracket 23 and the tube body 22 can also be detachably connected, such as by threaded connection or snap-fit.

[0051] Preferably, the tube body 22 is engaged with the first support 23. In some embodiments, such as Figure 8 and Figure 9 As shown, the tube body 22 is provided with a second slot 222, and the outer wall of the first bracket 23 is provided with a locking block 232. The first bracket 23 passes through the tube body 22, and after being installed in place, the locking block 232 is engaged in the second slot 222. Alternatively, in some embodiments not shown, the first bracket 23 is provided with a second slot 222, and the inner wall of the tube body 22 is provided with a locking block 232.

[0052] Furthermore, in some embodiments, such as Figure 3 and Figure 4 As shown, the pen body 1 includes a pen body portion 11 and a reinforcing portion 12. The reinforcing portion 12 is fixedly connected to one end of the pen body portion 11 along the first direction X, and the two together form a first receiving cavity 10; a first slot 121 is disposed on the reinforcing portion 12. In this embodiment, by providing the reinforcing portion 12 at the end of the pen body portion 11, it is convenient to arrange the first slot 121 to realize the installation of the battery module 2; and the reinforcing portion 12 can play a role in structural reinforcement of the pen body portion 11, thereby improving the reliability of the structural strength of the pen body 1.

[0053] It should be noted that the pen body 11 forms a pen tip at one end along the first direction X, and the reinforcing part 12 is provided at the end of the pen body 11 away from the pen tip.

[0054] The reinforcing part 12 is annular, and at least a portion of the structure of the reinforcing part 12 passes through the pen body part 11 and is fixedly connected to the pen body part 11. Exemplarily, the reinforcing part 12 and the wall part can be connected by adhesive, threaded connection, etc., preferably by adhesive, which is easy to assemble.

[0055] 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. For example, the reinforcing part 12 can be a metal part, such as hardware, to ensure structural strength.

[0056] Understandably, the battery module 2 is installed at one end of the pen body 1 where the reinforcing part 12 is provided, and at least a portion of the structure of the battery module 2 is located outside the first receiving cavity 10, that is, exposed outside the reinforcing part 12.

[0057] Furthermore, in some embodiments, such as Figure 1 , Figure 3 and Figure 11 As shown, the electronic pen also includes a second bracket 3, a main board component 4, and an electrical connector 5. The second bracket 3 passes through the first receiving cavity 10 and is located at one end of the main structure along the first direction X. The main board component 4 is disposed within the second bracket 3. The electrical connector 5 is fixedly connected to the second bracket 3, with one end of the connector 5 located inside the second bracket 3 and electrically connected to the main board component 4; the other end of the connector 5 is located outside the second bracket 3 and extends along the first direction X. The end of the main structure facing the second bracket 3 has a insertion hole 233, and the other end of the connector 5 is electrically connected to the main structure through the insertion hole 233. With this configuration, when the battery module 2 is installed, electrical connection to the main board component 4 can be achieved through the insertion hole 233 and the electrical connector 5, eliminating the need for additional electrical connection procedures, simplifying the assembly process of the battery module 2, and further improving the convenience of replacing the battery module 2.

[0058] Understandably, in this embodiment, multiple insertion holes 233 and electrical connectors 5 are provided. This invention does not specifically limit the number of insertion holes 233 and electrical connectors 5; the number of both depends on the electrical function of the battery module 2.

[0059] Specifically, such as Figure 1 and Figure 2 As shown, a cavity 30 is formed inside the second bracket 3, and the main board component 4 is disposed inside the cavity 30 and fixedly connected to the second bracket 3. This invention does not specifically limit the direction of the fixed connection between the main board component 4 and the second bracket 3. For example, the main board component 4 can be snapped into the inner wall of the second bracket 3, or indirectly connected through other structures.

[0060] In some embodiments, the electrical connector 5 may be disposed within the cavity 30; exemplarily, the end face of the second bracket 3 facing the battery module 2 is provided with a through hole, and one end of the electrical connector 5 extends out of the cavity 30 through the through hole to be electrically connected to the main structure. Exemplarily, such as... Figure 2 As shown, the electronic pen fixing block 6 is fixed inside the cavity 30 of the second bracket 3, and the electrical connector 5 passes through the fixing block 6.

[0061] In some embodiments not shown, the electrical connector 5 may also be disposed outside the cavity 30; for example, the electrical connector 5 is disposed on the end face of the second bracket 3 facing the battery module 2, and the end face is provided with a through hole, one end of the electrical connector 5 passes through the through hole into the cavity 30 and is electrically connected to the main board component 4.

[0062] For example, the electrical connector 5 can be soldered to the main board component 4, or the electrical connection can be achieved by bonding with conductive adhesive, etc. For example, the electrical connector 5 can be a metal conductor, or an electrical connector, etc.

[0063] Understandably, the first support 23 is located at the end of the pen body 1 near the pen tip, and the battery module 2 is located at the end of the pen body 1 away from the pen tip.

[0064] Furthermore, in some embodiments, such as Figure 5 As shown, the main structure includes a first support 23, a circuit board 24, and a battery 25. The first support 23 has a second receiving cavity 234 and the aforementioned insertion hole 233, which communicates with the second receiving cavity 234. The circuit board 24 is disposed within the second receiving cavity 234 and is positioned opposite to the insertion hole 233 along the first direction X. The electrical connector 5 is connected to the circuit board 24 through the insertion hole 233 for electrical connection with the circuit board 24. The battery 25 is disposed within the second receiving cavity 234 and is electrically connected to the circuit board 24. In this embodiment, the battery 25 is electrically connected to the circuit board 24, and the electrical connector 5 abuts against the circuit board 24 through the insertion hole 233, thereby achieving electrical connection between the battery 25 and the main board component 4, forming a circuit. With this configuration, as the battery module 2 is installed into the first receiving cavity 10, the battery 25 can form a circuit connection with the main board component 4 through the circuit board 24; and the telescopic component 21 is engaged with the first slot 121 to prevent the circuit board 24 and the electrical connector 5 from detaching from each other, making the installation method simple and reliable.

[0065] Specifically, the main structure also includes the aforementioned tube 22, with the first support 23 passing through and connected to the tube 22. For example... Figure 8 and Figure 9 As shown, the second receiving cavity 234 is open to facilitate the installation of the battery 25 and the circuit board 24; and when the first bracket 23 is inserted into the tube 22, the second receiving cavity 234 is located inside the tube 22, and the tube 22 plays a limiting role for the battery 25 and the circuit board 24 to prevent the battery 25 and the circuit board 24 from falling off.

[0066] In some embodiments, such as Figure 9 As shown, a stop 235 is provided inside the second receiving cavity 234. The stop 235 and the inner wall of the second receiving cavity 234 together form a slot, in which the circuit board 24 is snapped. It can be understood that along the first direction X, the circuit board 24 is located between the insertion hole 233 and the battery 25; and along the first direction X, the stop 235 is located between the circuit board 24 and the battery 25. That is, the stop 235 and the inner wall of the second receiving cavity 234 near the insertion hole 233 together form the aforementioned slot.

[0067] Furthermore, in some embodiments, the first support 23 abuts against the second support 3, such as... Figure 9 andFigure 11 As shown, the first bracket 23 has a first concave-convex structure 236 on its contact surface with the second bracket 3, and the second bracket 3 has a second concave-convex structure 31 on its contact surface with the first bracket 23. The first concave-convex structure 236 and the second concave-convex structure 31 fit together, the insertion hole 233 is provided on the first concave-convex structure 236, and the electrical connector 5 is provided on the second concave-convex structure 31. In this embodiment, the first concave-convex structure 236 and the second concave-convex structure 31 cooperate with each other to limit the installation direction of the battery module 2, so that the electrical connector 5 can be accurately inserted into the insertion hole 233 and abut against the circuit board 24.

[0068] Specifically, the first concave-convex structure 236 includes a first concave portion 2361 and a first convex portion 2362 sequentially arranged along the second direction Y, and the second concave-convex structure 31 includes a second concave portion 311 and a second convex portion 312 sequentially arranged along the second direction Y. The first concave portion 2361 is fitted with the second convex portion 312, and the first convex portion 2362 is fitted with the second concave portion 311. A insertion hole 233 is provided on the first concave portion 2361, and an electrical connector 5 is provided on the second convex portion 312. Understandably, the second convex portion 312 is hollow and communicates with the cavity 30 within the second bracket 3. The electrical connector 5 is fixed within the second convex portion 312 by the aforementioned fixing block 6 and extends out of the second bracket 3 through a through hole in the second convex portion 312.

[0069] The dimensions of the first recess 2361 and the second protrusion 312 in the second direction Y can be larger than the dimensions of the first protrusion 2362 and the second recess 311 in the second direction Y, so as to provide sufficient arrangement space for the electrical connector 5.

[0070] Alternatively, in some embodiments not shown, the insertion hole 233 is provided on the first protrusion 2362, and the electrical connector 5 is provided on the second recess 311.

[0071] In some embodiments, the electronic pen further includes a buffer 7, which is disposed between the first concave-convex structure 236 and the second concave-convex structure 31, and is misaligned with the insertion hole 233 and the electrical connector 5. The buffer 7 prevents the battery module 2 from shaking after being installed in the pen body 1, ensuring the stability of the circuit connection. For example, the buffer 7 can be a flexible material such as foam or silicone.

[0072] For example, such as Figure 2 As shown, the insertion hole 233 is disposed on the first recess 2361, the electrical connector 5 is disposed on the second protrusion 312, and the buffer 7 is disposed between the first protrusion 2362 and the second recess 311. For example, the buffer 7 can be fixedly connected to the end face of the second recess 311, such as by adhesive bonding.

[0073] For example, in some embodiments not shown, the insertion hole 233 is disposed on the first protrusion 2362, the electrical connector 5 is disposed on the second recess 311, and the buffer 7 is disposed between the first recess 2361 and the second protrusion 312.

[0074] In some embodiments, such as Figure 5 As shown, the main structure also includes a charging base 26 and a flexible electrical connector 27. The charging base 26 is disposed on the first support 23 and is located outside the first receiving cavity 10. Specifically, the charging base 26 is located at the end of the pen body 1 away from the pen tip. The flexible electrical connector 27 is electrically connected between the charging base 26 and the circuit board 24. For example, the flexible electrical connector 27 can be a flexible circuit board.

[0075] Specifically, such as Figure 9 As shown, the first bracket 23 has a third receiving cavity 237, and the charging base 26 is disposed within the third receiving cavity 237. The third receiving cavity 237 is open to facilitate the installation of the charging base 26. When the first bracket 23 passes through the tube 22, the third receiving cavity 237 is located within the tube 22, and the tube 22 acts as a limit for the charging base 26, preventing it from falling off. Exemplarily, the first bracket 23 also has a third opening 239, and the charging interface of the charging base 26 is directly opposite the third opening 239 to facilitate charging.

[0076] Understandably, the third receiving cavity 237 and the charging base 26 are located at the end of the first bracket 23 away from the circuit board 24, that is, away from the second bracket 3. Wherein, as Figure 9 As shown, a partition 238 is provided between the second receiving cavity 234 and the third receiving cavity 237. The second connecting hole 231 can be provided on the partition 238, that is, the telescopic member 21 can be telescopically provided in the partition 238.

[0077] In some embodiments, the main structure further includes a pen cap 28, which is fixedly connected to the end of the tube 22 away from the pen body 1. After the battery module 2 is installed inside the pen body 1, the pen cap 28 is disposed adjacent to the aforementioned reinforcing part 12. Figure 5 As shown, the tube body 22 and the pen cap 28 are sequentially fitted onto the outside of the charging base 26. Among them, as...
