Detailed Implementation

[0086] 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, and 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.

[0087] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of this application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0088] According to an embodiment of this application, an electronic pen is provided, comprising:

[0089] The pen body is a shell structure with an assembly cavity, and the pen body has an opening at its end in a first direction, which is the axial direction of the pen body.

[0090] A detachable component, which is detachably connected to the opening;

[0091] A power supply assembly is installed in the assembly cavity. The power supply assembly includes a battery, a motherboard, and a bracket, with the motherboard mounted on the bracket.

[0092] The battery is detachably connected to the bracket; or, the battery is detachably connected between the detachable component and the bracket.

[0093] The motherboard is connected to a positive terminal connector and a negative terminal connector. The positive terminal connector is in contact with the positive terminal of the battery, and the negative terminal connector is in contact with the negative terminal of the battery.

[0094] The electronic pen provided in this application embodiment detachably connects the battery to a bracket, or detachably connects it between a detachable component and a bracket. This eliminates the reliance on complex internal spaces or welding processes for battery installation and fixation, instead creating a modular structure with the detachable component and bracket as key nodes. When the battery needs to be replaced, simply disassembling the detachable component releases the axial constraint on the battery, allowing it to be easily removed from the assembly cavity. This design greatly simplifies battery installation and removal, effectively solving the problem of difficult battery removal and ensuring the electronic pen can quickly resume use when the battery is depleted, thus improving the product's battery life. Simultaneously, it avoids the complete failure of the pen due to a non-replaceable battery, extending the electronic pen's lifespan.

[0095] To facilitate better explanation and understanding, the following describes the solution of this application through two specific electronic pen product structures.

[0096] As shown in Figures 1 to 12, this application provides an electronic pen, which includes:

[0097] The pen body 1 is a shell structure with an assembly cavity. The pen body 1 has an opening 11 at its end in a first direction, wherein the first direction is the axial direction of the pen body 1.

[0098] Press component 2 is movably connected to opening 11.

[0099] The power supply component 3 is installed in the assembly cavity. The power supply component 3 includes a battery 31, a main board 32, a first bracket 33, and a second bracket 34. The two ends of the battery 31 in the first direction are detachably connected to the first bracket 33 and the second bracket 34, respectively. The main board 32 is installed on the first bracket 33. The second bracket 34 is detachably connected to the end of the pressing component 2 away from the opening 11. The main board 32 is connected to a positive electrode connector 321 and a negative electrode connector 322. The positive electrode connector 321 abuts against the positive electrode of the battery 31, and the negative electrode connector 322 abuts against the negative electrode of the battery 31.

[0100] As can be seen from the above embodiments, in this embodiment, since the battery 31 is detachably connected to the first bracket 33 and the second bracket 34 at both ends in the first direction, the main board 32 is mounted on the first bracket 33, and the second bracket 34 is detachably connected to the end of the pressing component 2 away from the opening 11. The main board 32 is connected to a positive electrode connector 321 and a negative electrode connector 322. The positive electrode connector 321 abuts against the positive electrode of the battery 31, and the negative electrode connector 322 abuts against the negative electrode of the battery 31. Therefore, when it is necessary to replace the battery 31, the pressing component 2 can be removed from the opening 11 of the pen body 1, and then the pressing component 2 and the second bracket 34 can be removed, so that the battery 31 can be taken out from the second bracket 34. When assembling the battery 31 into the electronic pen, the battery 31 can be first assembled onto the second bracket 34, and then the second bracket 34 and the pressing component 2 can be connected, so that the positive terminal connector 321 abuts against the positive terminal of the battery 31, and the negative terminal connector 322 abuts against the negative terminal of the battery 31. Then, the pressing component 2 can be movably connected to the opening 11. In summary, the electronic pen provided in this embodiment facilitates the installation and removal of the battery 31, which helps to improve the battery life and extend the lifespan of the electronic pen.

[0101] In the above embodiments, the pen body 1 can be a cylindrical shell structure, a square shell structure, or a shell structure of other shapes; this application embodiment does not limit this. The pen body 1 has an opening 11 at its end in the first direction, which can be understood as the pen body 1 being a cylindrical structure with a single-end opening 11, or in other words, the tail of the pen body 1 has an opening 11. It should be noted that in this application embodiment, the first direction can be understood as the axial direction of the pen body 1, that is, the direction of extension of the axis, and specifically the first direction can be the direction shown by X in Figure 3.

[0102] The pressing component 2, which is movably connected to the opening 11 of the pen body 1, is designed to pop out of the inner cavity of the pen body 1. The power supply component 3 includes a first bracket 33, which is a frame-like structure for fixing and mounting the motherboard 32. The first bracket 33 includes at least a plate-shaped fixing member, thus providing sufficient mounting space for the motherboard 32. The power supply component 3 includes a second bracket 34, which is a structure for fixing and mounting the battery 31. One end of the battery 31 can be connected to the end of the first bracket 33 via any of the detachable connection methods such as snap-fit, plug-in, or sleeve connection. The other end of the battery 31 can be connected to the end of the second bracket 34 via any of the detachable connection methods such as snap-fit, plug-in, or sleeve connection, thus allowing the battery 31 to be assembled using the first bracket 33 and the second bracket 34.

[0103] Furthermore, it should be noted that in the embodiments of this application, the positive terminal connector 321 and the negative terminal connector 322 on the motherboard 32 can be any kind of conductive electrical connector. The positive terminal connector 321 can be soldered to the positive terminal solder joint of the motherboard 32, and the negative terminal connector 322 can be soldered to the negative terminal solder joint of the motherboard 32.

[0104] In some embodiments, as shown in Figures 3 and 8, the pressing assembly 2 includes a first pressing cap 21, a pressing bracket 22, and an elastic recovery member 23. The first pressing cap 21 is connected to one end of the elastic recovery member 23 in a first direction, and the pressing bracket 22 is detachably connected to the opening 11. The pressing bracket 22 has a cylindrical structure with a movable chamber. The first end of the pressing bracket 22 and the second bracket 34 are detachably connected. One end of the elastic recovery member 23 is detachably connected to the first pressing cap 21. The first pressing cap 21 extends at least partially out of the opening 11, and the other end of the elastic recovery member 23 extends into the movable chamber. The elastic recovery member 23 is movably connected in the movable chamber to allow the first pressing cap 21 to switch between a first state and a second state. The first end and the second end are two opposite ends of the pressing bracket 22 in the first direction. In the first state, the first pressing cap 21 moves toward the power supply assembly 3, and the elastic recovery member 23 is in a compressed deformation state. In the second state, the first pressing cap 21 moves away from the power supply assembly 3, and the elastic recovery member 23 is in a recovery deformation state.

[0105] In this embodiment, the first pressing cap 21 is a pressing component with a pressing part and a connecting part. For example, the first pressing cap 21 may include a pressing sheet and a pressing rod, with the pressing sheet fixed to the end of the pressing rod. The elastic recovery component 23 may be an integral elastic structure or a composite elastic structure composed of multiple elastic components; this embodiment does not limit this. The pressing bracket 22 is a cylindrical structure with openings 11 at both ends. During installation, the elastic recovery component 23 can be inserted from one end of the pressing bracket 22 into the movable chamber of the pressing bracket 22, allowing the second bracket 34 to be detachably connected to the opening at one end of the pressing bracket 22. The first pressing cap 21 is inserted into the end of the elastic recovery component 23 near the opening 11, and then the pressing bracket 22 is detachably connected to the opening 11 of the pen body 1. Thus, when removing the pressing assembly 2, the pressing bracket 22 can be pulled out simply by separating it from the opening 11 of the pen body 1.

[0106] It should be noted that in this embodiment, since the first end of the pressing bracket 22 and the second bracket 34 are detachably connected, and one end of the elastic return member 23 is detachably connected to the first pressing cap 21, the first pressing cap 21 extends at least partially out of the opening 11, and the other end of the elastic return member 23 extends into the movable chamber, and the elastic return member 23 is movably connected in the movable chamber, so that the first pressing cap 21 switches between the first state and the second state. Therefore, when the battery 31 needs to be removed, the first pressing cap 21 can be pressed first, so that the first pressing cap 21 moves towards the power supply component 3, so that the elastic return member 23 is in a compressed deformation state under the combined action of the pressing bracket 22 and the first pressing cap 21. Then, the first pressing cap 21 is released, so that the elastic return member 23 is in a recovery deformation state. Then, under the action of the restoring force of the elastic return member 23, the first pressing cap 21 can be ejected from the movable chamber of the pressing bracket 22. In other words, the distance between the first pressing cap 21 and the end of the pen body 1 where the opening 11 is set increases. In this way, with the first pressing cap 21 in the second state, sufficient installation space is provided for disassembling the pressing bracket 22 and the pen body 1, while also meeting the usage needs of the electronic pen in certain specific scenarios. For example, when the electronic pen is installed on a related electronic device, pressing the first pressing cap 21 will cause it to be in the second state, thereby separating the electronic pen from the electronic device. This electronic device can be any of the following: a smart mobile device, a smart wearable device, a smart display device, etc.; this embodiment does not limit this.

[0107] In some embodiments, as shown in Figures 5 and 10, a first buckle 221 is provided on the outer wall of the first end of the pressing bracket 22, and a first slot 12 is provided on the inner wall of the pen body 1 at the opening 11, and the first buckle 221 is engaged in the first slot 12.

[0108] In this embodiment, there are at least two first latches 221, and the number of first slots 12 is the same as the number of first latches 221. Taking two first latches 221 as an example, the two first latches 221 are located on the two side walls of the first end of the pressing bracket 22 in the second direction, and the two first latches 221 are respectively engaged with the two first slots 12. In this way, by engaging the first latches 221 with the first slots 12, the pressing bracket 22 and the pen body 1 are engaged, so that when disassembling the pen body 1 and the pressing bracket 22, it is only necessary to separate the first latches 221 from the first slots 12, which facilitates the disassembly of the pen body 1 and the pressing bracket 22. Here, the second direction is the direction intersecting with the first direction.

[0109] In some embodiments, a first through groove structure 222 is provided on the periphery of the first buckle 221, and a guide groove 13 is provided at one end of the pen body 1 where the opening 11 is provided, the guide groove 13 extending to the outside of the opening 11 in a first direction.

[0110] In this embodiment, the first through-slot structure 222 can be disposed at the end of the first buckle 221 facing the battery 31 in the first direction and on the two sides of the first buckle 221 in a third direction, where the third direction is the direction that intersects both the first and second directions. For example, the first through-slot structure 222 can be a U-shaped first through-slot structure 222, with the first buckle 221 surrounded by the U-shaped first through-slot structure 222. Thus, since the first through-slot structure 222 is provided on the periphery of the first buckle 221, a deformation space for the first buckle 221 can be formed through the first through-slot structure 222, which is beneficial for the separation of the first buckle 221 and the first slot 12. Furthermore, since the pen body 1 has a guide groove 13 at one end where the opening 11 is located, and the guide groove 13 extends along the first direction to the outside of the opening 11, the first buckle 221 can both engage with the first slot 12 under the guidance of the guide groove 13 and be detached from the pen body 1 under the guidance of the guide groove 13.

[0111] In some embodiments, as shown in Figures 8, 10, and 11, the elastic recovery member 23 includes a first elastic member 231, a second elastic member 232, and a rotating shaft 233; the rotating shaft 233 includes a limiting protrusion ring 2331, which includes two first limiting surfaces 23311 and a second limiting surface 23312 arranged opposite to each other along a first direction; the end of the second bracket 34 facing the opening 11 is provided with a movable hole 341, and the wall of the movable hole 341 is provided with a first shoulder structure 342; the end of the rotating shaft 233 away from the opening 11 is inserted into the movable hole 341, and the movable chamber is close to the opening 11. A second shoulder structure 223 is provided on the inner wall of the end of the opening 11; one end of the first elastic member 231 abuts against the first shoulder structure 342, and the other end of the first elastic member 231 abuts against the first limiting surface 23311; one end of the second elastic member 232 abuts against the second limiting surface 23312, and the other end of the second elastic member 232 abuts against the second shoulder structure 223; in the first state, both the first elastic member 231 and the second elastic member 232 are in a state of compression deformation, and in the second state, both the first elastic member 231 and the second elastic member 232 are in a state of recovery deformation.

[0112] In this embodiment, the first elastic element 231 and the second elastic element 232 can be elastic rubber rings, springs, or other elastic structures, and this application embodiment does not limit this. The rotating shaft 233 is a rod-shaped structure extending along the first direction. A limiting protrusion ring 2331 is provided in the middle of the rotating shaft 233. The limiting protrusion ring 2331 can be understood as an annular protrusion structure arranged circumferentially around the rotating shaft 233, thereby allowing the limiting protrusion ring 2331 to have a first limiting surface 23311 and a second limiting surface 23312 arranged opposite to each other along the first direction. The movable hole 341 provided at the end of the second bracket 34 facing the opening 11 can provide sufficient space for the movement of the rotating shaft 233. A first shoulder structure 342 is provided on the wall of the movable hole 341, and a second shoulder structure 223 is provided on the inner wall of the movable chamber near the end of the opening 11. The first shoulder structure 342 and the second shoulder structure 223 can be understood as a variable-diameter platform structure. In other words, the first shoulder structure 342 may include a platform opposite to the first limiting surface 23311, and the second shoulder structure 223 may include a platform opposite to the second limiting surface 23312. During installation, one end of the first elastic member 231 can be pressed against the first shoulder structure 342, and the other end of the first elastic member 231 can be pressed against the first limiting surface 23311. One end of the second elastic member 232 can be pressed against the second limiting surface 23312, and the other end of the second elastic member 232 can be pressed against the second shoulder structure 223. In the first state, the first pressing cap 21 can move towards the power supply component 3, causing the end of the rotating shaft 233 near the battery 31 to extend into the movable hole 341. This compresses the first elastic member 231 located between the first shoulder structure 342 and the first limiting surface 23311, and also compresses the second elastic member 232 located between the second shoulder structure 223 and the second limiting surface 23312. Afterward, the force applied to the first pressing cap 21 is released, placing it in the second state. This allows both the first elastic member 231 and the second elastic member 232 to return to their original deformation state. Consequently, under the elastic force of the first elastic member 231 and the second elastic member 232, the first pressing cap 21 and the rotating shaft 233 move away from the power supply component 3, increasing the distance between the first pressing cap 21 and the end of the pen body 1 where the opening 11 is located.

[0113] In some embodiments, the elastic recovery member 23 further includes a rotating ring 234, through which the rotating shaft 233 passes; the rotating ring 234 includes a first toothed surface 2341, and the limiting protrusion ring 2331 includes a second toothed surface 23313. The first toothed surface 2341 and the second toothed surface 23313 are disposed opposite to each other. The outer wall of the rotating ring 234 is provided with a first sliding protrusion 2342 extending in a first direction, and the outer wall of the limiting protrusion ring 2331 is provided with a second sliding protrusion 23314 extending in a first direction. The inner wall of the movable chamber is provided with a sliding groove 224 extending in a first direction. In the first state, the first toothed surface 2341 moves away from the second toothed surface 23313, and the rotating ring 234 moves toward the direction closer to the battery 31. In the second state, the first toothed surface 2341 and the second toothed surface 23313 mesh, and the rotating ring 234 moves away from the battery 31. The first sliding protrusion 2342 and the second sliding protrusion 23314 are both slidably connected in the sliding groove 224.

[0114] In this embodiment, the rotating ring 234 can be understood as a circular ring structure. The end face of the rotating ring 234 facing the opening 11 is the first toothed surface 2341, and the surface of the limiting protrusion ring 2331 facing the battery 31 is the second toothed surface 23313. Both the first toothed surface 2341 and the second toothed surface 23313 are wavy end face structures with interlocking teeth. Specifically, the first toothed surface 2341 may include multiple first pointed teeth, and there is a first tooth groove between each two adjacent first pointed teeth. The second toothed surface 23313 may include multiple second pointed teeth, and there is a second tooth groove between each two adjacent second pointed teeth. The first pointed teeth can be engaged in the second tooth groove, and the second pointed teeth can be engaged in the first tooth groove. In this way, in the first state, the first pressing cap 21 can move towards the power supply component 3, so that the end of the rotating shaft 233 near the battery 31 extends into the movable hole 341, thereby causing the first elastic member 231 and the second elastic member 232 to be in a compressed state. At the same time, the first tooth surface 2341 moves away from the second tooth surface 23313, that is, the first tooth and the second tooth abut against each other, thereby causing the first tooth surface 2341 to move away from the second tooth surface 23313, driving the drive shaft to move away from the opening 11 until it extends into the movable hole 341 of the second bracket 34. Afterwards, the force applied to the first pressing cap 21 is released, so that the first pressing cap 21 is in the second state. In this state, the first tooth surface 2341 and the second tooth surface 23313 are engaged, the sliding ring moves away from the battery 31, and the first sliding protrusion 2342 and the second sliding protrusion 23314 are slidably connected in the sliding groove 224. This causes the drive shaft to lose the thrust of the rotating ring 234, so that the first elastic element 231 and the second elastic element 232 are both in the recovery deformation state. The first pressing cap 21 and the rotating shaft 233 can move away from the power supply component 3 under the elastic force of the first elastic element 231 and the elastic force of the second elastic element 232, thereby increasing the distance between the first pressing cap 21 and the end of the pen body 1 where the opening 11 is provided.

[0115] In some embodiments, at least one of the positive electrode connector 321 and the negative electrode connector 322 is an elastic connector.

[0116] In this embodiment, since at least one of the positive electrode connector 321 and the negative electrode connector 322 is an elastic connector, the positive electrode connector 321 and the negative electrode connector 322 can also be elastic. This not only allows the positive electrode connector 321 and the negative electrode connector 322 to provide a certain elastic force when the first pressing cap 21 switches between the first state and the second state, but also provides a certain installation allowance when the battery 31 is installed between the first bracket 33 and the second bracket 34, facilitating the assembly of the power supply component 3. It should be noted that the elastic connector can be a spring, a sheet, or other elastic components, and this embodiment does not limit this.

[0117] In some embodiments, the positive electrode connector 321 is a spring and the negative electrode connector 322 is a spring sheet, or both the positive electrode connector 321 and the negative electrode connector 322 are springs.

[0118] In this embodiment, when the positive terminal connector 321 is a spring and the negative terminal connector 322 is a spring sheet, the positive terminal of the battery 31 can be located at the end of the battery 31 facing the motherboard 32, and the negative terminal of the battery 31 can be located at the side of the battery 31. The positive terminal connector 321 can directly abut against the positive terminal of the battery 31, and the negative terminal connector 322 can extend from the side to the side of the battery 31 and abut against the negative terminal of the battery 31. In this way, the stability of the electrical connection between the battery 31 and the motherboard 32 can be ensured, and the wiring of the positive terminal connector 321 and the negative terminal connector 322 can be separated to avoid short circuits. When both the positive terminal connector 321 and the negative terminal connector 322 are springs, the positive terminal and the negative terminal of the battery 31 are both located at the end of the battery 31 facing the motherboard 32. Similarly, the stability of the electrical connection between the battery 31 and the motherboard 32 can be ensured.

[0119] In some embodiments, the end of the first bracket 33 facing the second bracket 34 is provided with a receiving portion 331; the end of the battery 31 away from the opening 11 is inserted into the receiving portion 331.

[0120] In this embodiment, the receiving portion 331 can be a tubular structure, thereby providing sufficient insertion space for the end of the battery 31 away from the opening 11.

[0121] In some embodiments, the receiving portion 331 is further provided with a guide groove 3311, through which at least one of the positive electrode connector 321 or the negative electrode connector 322 passes.

[0122] In this embodiment, since at least one of the positive electrode connector 321 or the negative electrode connector 322 passes through the guide groove 3311, at least one of the positive electrode connector 321 or the negative electrode connector 322 can be guided through the guide groove 3311 to pass through the receiving portion 331 and connect to the battery 31, thereby ensuring the stability of the electrical connection between the battery 31 and the motherboard 32. For example, the guide groove 3311 can be formed in the middle of the receiving portion 331, and the guide groove 3312 can be formed on the side wall of the receiving portion 331, so that the positive electrode connector 321 passes through the guide groove 3311 from the middle of the receiving portion 331 into the interior of the receiving portion 331 and contacts the positive electrode of the battery 31, and the negative electrode connector 322 passes through the guide groove 3312 from the outside of the receiving portion 331 to the end of the receiving portion 331 and then returns to the interior of the receiving portion 331 to contact the negative electrode of the battery 31.

[0123] In some embodiments, the second bracket 34 includes a first mounting portion 343 and a second mounting portion 344; the first mounting portion 343 is detachably connected to the first end of the pressing bracket 22, and the end of the battery 31 facing the opening 11 in the first direction is inserted into the second mounting portion 344.

[0124] In this embodiment, the first mounting part 343 can be a columnar structure, and the second mounting part 344 can be a cylindrical structure. The first mounting part 343 can be inserted into the first end of the second bracket 34, or a second buckle can be provided on the outside of the first mounting part 343, and a second slot can be provided at the first end of the pressing bracket 22, so that the second buckle and the first slot 12 engage, thereby making the first mounting part 343 detachably connected to the first end of the pressing bracket 22. In this way, since the first mounting part 343 is detachably connected to the first end of the pressing bracket 22, and the end of the battery 31 facing the opening 11 in the first direction is inserted into the second mounting part 344, the battery 31 can be detachably connected to the second bracket 34, and the second bracket 34 and the pressing bracket 22 can be detachably connected, thereby facilitating the installation and removal of the battery 31.

[0125] In some embodiments, an elastic buffer 4 is further provided between the end of the battery 31 facing the opening 11 in the first direction and the first mounting portion 343.

[0126] In this embodiment, since an elastic buffer 4 is provided between the end of the battery 31 facing the opening 11 in the first direction and the first mounting portion 343, the stability of the battery 31 connection can be ensured by the elastic buffer 4, and the battery 31 can be prevented from making abnormal noises or becoming loose. It should be noted that the elastic buffer 4 can be a structure such as foam or rubber pad, and this embodiment of the application does not limit it.

[0127] As can be seen from the above embodiments, in this embodiment, since the battery 31 is detachably connected to the first bracket 33 and the second bracket 34 at both ends in the first direction, the main board 32 is mounted on the first bracket 33, and the second bracket 34 is detachably connected to the end of the pressing component 2 away from the opening 11. The main board 32 is connected to a positive electrode connector 321 and a negative electrode connector 322. The positive electrode connector 321 abuts against the positive electrode of the battery 31, and the negative electrode connector 322 abuts against the negative electrode of the battery 31. Therefore, when it is necessary to replace the battery 31, the pressing component 2 can be removed from the opening 11 of the pen body 1, and then the pressing component 2 and the second bracket 34 can be removed, so that the battery 31 can be taken out from the second bracket 34. When assembling the battery 31 into the electronic pen, the battery 31 can be first assembled onto the second bracket 34, and then the second bracket 34 and the pressing component 2 can be connected, so that the positive terminal connector 321 abuts against the positive terminal of the battery 31, and the negative terminal connector 322 abuts against the negative terminal of the battery 31. Then, the pressing component 2 can be movably connected to the opening 11. In summary, the electronic pen provided in this embodiment facilitates the installation and removal of the battery 31, which helps to improve the battery life and extend the lifespan of the electronic pen.

[0128] As shown in Figures 13 to 26, this application embodiment provides another electronic pen, which includes:

[0129] The pen body 1 is a shell structure with an assembly cavity. The pen body 1 has an opening 11 at its end in a first direction, wherein the first direction is the axial direction of the pen body 1.

[0130] Pen cap 5 is detachably connected to opening 11, and pen cap 5 extends at least partially out of opening 11.

[0131] The power supply component 3 is installed in the assembly cavity. The power supply component 3 includes a battery 31, a third bracket 35 and a main board 32. The first end of the battery 31 is detachably connected to the third bracket 35, and the second end of the battery 31 is detachably connected to the pen cap 5. The main board 32 is installed on the third bracket 35. The first end and the second end are two opposite ends of the battery 31 in the first direction.

[0132] The motherboard 32 is connected to a positive terminal connector 321 and a negative terminal connector 322. The positive terminal connector 321 is in contact with the positive terminal of the battery 31, and the negative terminal connector 322 is in contact with the negative terminal of the battery 31.

[0133] As can be seen from the above embodiments, in this application embodiment, since the first end of the battery 31 is detachably connected to the third bracket 35, the second end of the battery 31 is detachably connected to the pen cap 5, the main board 32 is mounted on the third bracket 35, and the main board 32 is connected to a positive terminal connector 321 and a negative terminal connector 322. The positive terminal connector 321 abuts against the positive terminal of the battery 31, and the negative terminal connector 322 abuts against the negative terminal of the battery 31. Therefore, when it is necessary to replace the battery 31, the pen cap 5 can be removed from the opening 11 of the pen body 1, and then the first end of the battery 31 and the third bracket 35 can be separated. Finally, the second end of the battery 31 and the pen cap 5 can be separated, thus realizing the disassembly of the battery 31. When assembling the battery 31 into the electronic pen, the second end of the battery 31 can be connected to the pen cap 5 first, and then the second end of the battery 31 can be connected to the third bracket 35, so that the positive terminal connector 321 abuts against the positive terminal of the battery 31, and the negative terminal connector 322 abuts against the negative terminal of the battery 31. Then, the pen cap 5 is connected to the opening 11. In summary, the electronic pen provided in this embodiment facilitates the installation and removal of the battery 31, which helps to improve the battery life and extend the lifespan of the electronic pen.

[0134] In the above embodiments, the pen body 1 can be a cylindrical shell structure, a square shell structure, or a shell structure of other shapes; this application embodiment does not limit this. The pen body 1 has an opening 11 at its end in the first direction, which can be understood as the pen body 1 being a cylindrical structure with a single-end opening 11, or in other words, the tail of the pen body 1 has an opening 11. It should be noted that in this application embodiment, the first direction can be understood as the axial direction of the pen body 1, that is, the direction of extension of the axis, and specifically the first direction can be the direction shown by X in Figures 15 and 22.

[0135] It should be noted that, in the embodiments of this application, the positive terminal connector 321 and the negative terminal connector 322 on the motherboard 32 can be any kind of conductive electrical connector. The positive terminal connector 321 can be soldered to the positive terminal solder joint of the motherboard 32, and the negative terminal connector 322 can be soldered to the negative terminal solder joint of the motherboard 32.

[0136] Furthermore, in this embodiment, the third bracket 35 is primarily a frame structure for fixing and mounting the motherboard 32. The third bracket 35 includes at least a plate-shaped fixing member, thereby providing sufficient mounting space for the motherboard 32. Simultaneously, the end of the third bracket 35 facing the opening 11 can be used to connect with the first end of the battery 31. The connection method between the end of the third bracket 35 facing the opening 11 and the first end of the battery 31 can be any of the detachable connection methods such as snap-fit, plug-in, or sleeve-type connection. Alternatively, the first end of the battery 31 can be directly pressed against the end of the third bracket 35 facing the opening 11. This embodiment does not limit this approach. The pen cap 5 includes at least a pressing member with a pressing part 51 and a connecting part 52. For example, the pressing part 51 can be a pressing sheet, and the connecting part 52 can be a pressing rod. The pressing sheet is fixed to the end of the pressing rod. The part of the pen cap 5 that connects to the second end of the battery 31 is the connecting part 52. The connection method between the connecting part 52 and the second end of the battery 31 can be any of the detachable connection methods such as snap-fit, plug-in, or sleeve connection. Alternatively, the second end of the battery 31 can be directly pressed against the end face of the connecting part 52. This application embodiment does not limit this.

[0137] Regarding the connection method of connecting the battery 31 to the third bracket 35 and the pen cap 5, the battery 31 can be inserted between the third bracket 35 and the pen cap 5, or the battery 31 can be abutted between the third bracket 35 and the pen cap 5, or it can be fixed between the third bracket 35 and the pen cap 5 in other detachable ways. This application embodiment does not limit this. The following will describe the connection method using the battery 31 inserted between the third bracket 35 and the pen cap 5 and the connection method using the battery 31 abutting between the third bracket 35 and the pen cap 5 as examples, as detailed below:

[0138] In one possible implementation, as shown in Figures 13 to 19, in some embodiments, the pen cap 5 includes a pressing portion 51 and a connecting portion 52; the pressing portion 51 extends out of the opening 11, and the connecting portion 52 includes a first latching arm 521 and a second latching arm 522 disposed opposite to each other along a second direction, the first latching arm 521 and the second latching arm 522 forming an insertion cavity; the second end of the battery 31 is inserted into the insertion cavity, wherein the second direction intersects the first direction.

[0139] In this embodiment, the pressing part 51 can be a component that provides gripping and pressing. The pressing part 51 can be a sheet-like structure, a plate-like structure, or a structure of other shapes. The connecting part 52 includes a first latching arm 521 and a second latching arm 522, both of which extend in a first direction. For example, the connecting part 52 can be a cylindrical structure with a through groove extending in the first direction to the end. The through groove separates the first latching arm 521 and the second latching arm 522, so that an insertion cavity is formed between the first latching arm 521 and the second latching arm 522. In this way, since the first latching arm 521 and the second latching arm 522 form an insertion cavity, the second end of the battery 31 is inserted into the insertion cavity. Therefore, when the pen cap 5 is removed from the opening of the pen body 1, it is only necessary to pull out the battery 31 from the insertion cavity, which facilitates the separation between the battery 31 and the pen cap 5. It should be noted that the surface of the first card connector 521 facing the second card connector 522 and the surface of the second card connector 522 facing the first card connector 521 can be curved, which can increase the contact area between the first card connector 521 and the surface of the battery 31, and increase the contact area between the second card connector 522 and the surface of the battery 31.

[0140] In some embodiments, the pen cap 5 further includes a third elastic member 53; the third elastic member 53 includes a first waterproof portion 531 and a first buffer portion 532. The first waterproof portion 531 is embedded in the outer wall of the pen cap 5 at a first position, which is the position where the connection between the pressing portion 51 and the connecting portion 52 is located. The first buffer portion 532 extends into the insertion cavity and abuts against the end of the second end of the battery 31.

[0141] In this embodiment, the third elastic member 53 can be any of the following materials: neoprene rubber, butyl rubber, EPDM rubber, polyvinyl chloride, polyisobutylene, and polyurethane. This application embodiment does not limit the specific materials used. The first waterproof portion 531 included in the third elastic member 53 can be an annular structure, allowing it to be fitted onto the outer wall of the connection between the pressing portion 51 and the connecting portion 52. For example, an insert groove can be formed on the outer wall of the connection between the pressing portion 51 and the connecting portion 52, allowing the first waterproof portion 531 to be embedded in the groove. The first buffer portion 532 included in the third elastic member 53 can be a block structure, a frame structure, or other shapes. This application embodiment does not limit the specific shapes used. The first buffer portion 532 extends into the insertion cavity, allowing a portion of the first buffer portion 532 to be located between the first snap-fit ​​arm 521 and the second snap-fit ​​arm 522, thereby improving the overall strength of the pen cap 5. Thus, since the first waterproof part 531 is embedded on the outer wall of the first position of the pen cap 5, the first position is the position where the connection between the pressing part 51 and the connecting part 52 is located. The first buffer part 532 extends into the insertion cavity and abuts against the end of the second end of the battery 31. Therefore, the first waterproof part 531 can be located in the gap between the pen cap 5 and the pen body 1, thereby preventing external water vapor and other contaminants from entering the electronic pen and improving the waterproof performance of the electronic pen. At the same time, the first buffer part 532 can provide buffer for the second end of the battery 31, ensuring the stability of the electrical connection between the battery 31 and the motherboard 32, and ensuring that the battery 31 does not make any abnormal noise.

[0142] In some embodiments, the end of the third bracket 35 facing the pen cap 5 includes a third snap-fit ​​arm 351 and a fourth snap-fit ​​arm 352 disposed opposite to each other in the second direction. The third snap-fit ​​arm 351 and the fourth snap-fit ​​arm 352 form a snap-fit ​​cavity, and the first end of the battery 31 is snapped into the snap-fit ​​cavity.

[0143] In this embodiment, both the third latching arm 351 and the fourth latching arm 352 extend in the first direction. For example, the end of the third bracket 35 facing the pen cap 5 can be a cylindrical structure. A through groove extending in the first direction is formed on the cylindrical structure, and the third latching arm 351 and the fourth latching arm 352 are separated by the through groove, so that a latching cavity is formed between the third latching arm 351 and the fourth latching arm 352. In this way, since the third latching arm 351 and the fourth latching arm 352 form a latching cavity, the first end of the battery 31 is latched in the latching cavity, so it is convenient to insert the first end of the battery 31 into the latching cavity and to remove the battery 31 from the latching cavity. Similarly, similar to the first card connector arm 521 and the second card connector arm 522, the surface of the third card connector arm 351 facing the fourth card connector arm 352 and the surface of the fourth card connector arm 352 facing the third card connector arm 351 can be curved, thereby increasing the contact area between the third card connector arm 351 and the surface of the battery 31, and increasing the contact area between the fourth card connector arm 352 and the surface of the battery 31.

[0144] In some embodiments, a limiting groove 311 is provided on the surface of the second end of the battery 31, a first limiting protrusion 5211 is provided on the inner wall of the first latching arm 521 facing the second latching arm 522, and a second limiting protrusion is provided on the inner wall of the second latching arm 522 facing the first latching arm 521, and both the first limiting protrusion 5211 and the second limiting protrusion are engaged in the limiting groove 311.

[0145] In this embodiment, since a limiting groove 311 is provided on the surface of the second end of the battery 31, a first limiting protrusion 5211 is provided on the inner wall of the first latching arm 521 facing the second latching arm 522, and a second limiting protrusion is provided on the inner wall of the second latching arm 522 facing the first latching arm 521. Both the first limiting protrusion 5211 and the second limiting protrusion are engaged in the limiting groove 311. Therefore, the stability of the connection between the battery 31 and the pen cap 5 can be improved by the cooperation of the first limiting protrusion 5211 and the limiting groove 311, and the cooperation of the second limiting protrusion and the limiting groove 311.

[0146] In another possible implementation, as shown in Figures 20 to 24, in some embodiments, the pen cap 5 includes a second press cap 54 and a connecting frame 55, the second press cap 54 extending out of the opening 11, and the second end of the battery 31 abutting against the end of the connecting frame 55 away from the opening 11.

[0147] In this embodiment, since the pen cap 5 includes a second pressing cap 54 and a connecting frame 55, the second pressing cap 54 extends out of the opening 11, and the second end of the battery 31 abuts against the end of the connecting frame 55 away from the opening 11, the pen cap 5 and the battery 31 can be separated after the pen body 1 is separated, which facilitates the disassembly of the battery 31.

[0148] In some embodiments, the pen cap 5 further includes a fourth elastic member 56, which includes a second waterproof portion 561 and a second buffer portion 562. The second waterproof portion 561 is embedded in the outer wall of a second position of the pen cap 5, which is the position where the connection between the second press cap 54 and the connecting frame 55 is located. The second buffer portion 562 is nested in the outer wall of the connecting frame 55 and extends to the end of the connecting frame 55 away from the second press cap 54. The second buffer portion 562 abuts against the end face of the second end of the battery 31.

[0149] In this embodiment, the fourth elastic member 56 can be any of the following materials: neoprene rubber, butyl rubber, EPDM rubber, polyvinyl chloride, polyisobutylene, and polyurethane. This application does not limit the specific materials used. The second waterproof portion 561 included in the fourth elastic member 56 can be an annular structure, allowing it to be fitted onto the outer wall of the second position of the pen cap 5. The second position is the location of the connection between the second pressing cap 54 and the connecting frame 55. For example, an insert groove can be formed on the outer wall of the connection between the pressing portion 51 and the connecting portion 52, allowing the second waterproof portion 561 to be embedded in the insert groove. The second buffer portion 562 can be a cylindrical structure, a frame structure, or other shapes. Thus, since the second waterproof part 561 is embedded in the outer wall of the second position of the pen cap 5, which is the location of the connection between the second pressing cap 54 and the connecting frame 55, and the second buffer part 562 is nested in the outer wall of the connecting frame 55 and extends to the end of the connecting frame 55 away from the second pressing cap 54, and the second buffer part 562 abuts against the end face of the second end of the battery 31, the second waterproof part 561 can be located in the gap between the pen cap 5 and the pen body 1, thereby preventing external water vapor and other contaminants from entering the electronic pen and improving the waterproof performance of the electronic pen. At the same time, the second buffer part 562 provides a buffer for the second end of the battery 31, ensuring the stability of the electrical connection between the battery 31 and the motherboard 32, ensuring that the battery 31 does not make any abnormal noise, and the second buffer part 562 can provide the elastic force of the pen cap 5 abutting against the second end of the battery 31, which can ensure the stability of the pen cap 5 after it abuts against the second end of the battery 31. It should be noted that since the second buffer part 562 is nested on the outer wall of the connecting frame 55, the overall strength of the pen cap 5 can be increased by the second buffer part 562, and the waterproof performance of the connecting frame 55 can be further enhanced by the second buffer part 562.

[0150] In some embodiments, the end of the third bracket 35 facing the pen cap 5 includes a pressing surface, and the first end of the battery 31 abuts against the pressing surface.

[0151] In this embodiment, since the end of the third bracket 35 facing the pen cap 5 includes a pressing surface, and the first end of the battery 31 abuts against the pressing surface, coupled with the second end of the battery 31 abutting against the end of the connecting frame 55 away from the opening 11, the battery 31 is abutted between the pen cap 5 and the third bracket 35. That is, the battery 31 is installed and fixed through the positioning of the third bracket 35 and the pen cap 5. There are no connecting parts between the battery 31 and the third bracket 35, and no connecting parts between the battery 31 and the pen cap 5. Thus, when removing the battery 31, it is only necessary to separate the pen cap 5 from the pen body 1, which facilitates the disassembly of the battery 31. Furthermore, the type and shape of the battery 31 are not limited; in other words, the shape of the battery 31 abutting between the pen cap 5 and the third bracket 35 is not limited.

[0152] In some embodiments, a third buckle 57 is provided on the surface of the pen cap 5 facing the pen body 1, and a first slot 12 is provided on the inner wall of the pen body 1 at the opening 11, and the third buckle 57 is engaged in the first slot 12.

[0153] In this embodiment, there are at least two third clips 57, and the number of first slots 12 is the same as the number of third clips 57. Taking two third clips 57 as an example, the two third clips 57 are located on two side walls in the second direction at the end of the pen cap 5 near the opening 11, and each of the two third clips 57 engages with a first slot 12. In this way, the pen cap 5 and the pen body 1 are engaged by the engagement of the third clips 57 and the first slots 12, so that when disassembling the pen body 1, it is only necessary to separate the third clips 57 from the first slots 12, which facilitates the disassembly of the pen body 1 and the pen cap 5. The second direction mentioned above is the direction that intersects with the first direction.

[0154] In some embodiments, the third buckle 57 has a second through groove structure 58 on its periphery, and the pen body 1 has a guide groove 13 at one end where the opening 11 is provided, the guide groove 13 extending to the outside of the opening 11 along the first direction.

[0155] In this embodiment, the second through-slot structure 58 can be disposed at the end of the third buckle 57 facing the battery 31 in the first direction and on the two sides of the third buckle 57 in a third direction, where the third direction intersects both the first and second directions. For example, the second through-slot structure 58 can be a U-shaped second through-slot structure 58, with the first latch surrounded by the U-shaped second through-slot structure 58. Thus, since the second through-slot structure 58 is provided on the periphery of the third buckle 57, a deformation space for the third buckle 57 can be formed through the second through-slot structure 58, which facilitates the separation of the third buckle 57 from the first latch 12. Furthermore, since the pen body 1 has a guide groove 13 at one end where the opening 11 is located, and the guide groove 13 extends along the first direction to the outside of the opening 11, the third buckle 57 can both engage with the first latch 12 under the guidance of the guide groove 13 and be detached from the pen body 1 under the guidance of the guide groove 13.

[0156] In some embodiments, at least one of the positive electrode connector 321 and the negative electrode connector 322 is an elastic connector.

[0157] In this embodiment, since at least one of the positive electrode connector 321 and the negative electrode connector 322 is an elastic connector, the positive electrode connector 321 and the negative electrode connector 322 can also be elastic. This not only allows the positive electrode connector 321 and the negative electrode connector 322 to provide a certain elastic force when the second pressing cap 54 switches between the first state and the second state, but also provides a certain installation allowance when the battery 31 is installed between the third bracket 35 and the pen cap 5, facilitating the assembly of the battery 31. It should be noted that the elastic connector can be a spring, a sheet, or other elastic components, and this embodiment does not limit this.

[0158] In some embodiments, the positive electrode connector 321 is a spring and the negative electrode connector 322 is a spring sheet, or both the positive electrode connector 321 and the negative electrode connector 322 are springs.

[0159] In this embodiment, when the positive terminal connector 321 is a spring and the negative terminal connector 322 is a spring sheet, the positive terminal of the battery 31 can be located at the end of the battery 31 facing the motherboard 32, and the negative terminal of the battery 31 can be located at the side of the battery 31. The positive terminal connector 321 can be directly connected to the positive terminal of the battery 31, and the negative terminal connector 322 can extend from the side to the side of the battery 31 and abut against the negative terminal of the battery 31. In this way, the stability of the electrical connection between the battery 31 and the motherboard 32 can be ensured, and the wiring of the positive terminal connector 321 and the negative terminal connector 322 can be separated to avoid short circuits. When both the positive terminal connector 321 and the negative terminal connector 322 are springs, both the positive and negative terminals of the battery 31 are located at the end of the battery 31 facing the motherboard 32. Similarly, the stability of the electrical connection between the battery 31 and the motherboard 32 can be ensured.

[0160] In some embodiments, when the positive electrode connector 321 is a spring and the negative electrode connector 322 is a spring sheet, the negative electrode of the battery 31 is located on the side wall of the battery 31, and the positive electrode of the battery 31 is located on the end face of the first end of the battery 31. The positive electrode of the battery 31 is electrically connected to the main board 32 via the spring. The spring sheet includes a connecting piece 3221 and a connecting arm 3222 connected to the main board 32. The connecting arm 3222 is attached to the side wall of the third bracket 35 facing the end of the battery 31. A connecting groove 355 is provided on the side wall of the third bracket 35 facing the end of the battery 31. An elastic pressure piece 32221 is provided on the connecting arm 3222. The elastic pressure piece 32221 presses against the negative electrode of the battery 31 through the connecting groove 355.

[0161] In this embodiment, since the spring includes a connecting piece 3221 and a connecting arm 3222 connected to the motherboard 32, and the connecting arm 3222 attached to the side wall of the end of the third bracket 35 facing the battery 31, the connecting piece 3221 can ensure the electrical connection strength between the spring and the motherboard 32, and the connecting arm 3222 and the positive terminal connector 321 can be separated to avoid short circuit. Furthermore, since a connecting groove 355 is provided on the side wall of the end of the third bracket 35 facing the battery 31, and an elastic pressure plate 32221 is provided on the connecting arm 3222, the elastic pressure plate 32221 presses against the negative terminal of the battery 31 through the connecting groove 355. Therefore, the connecting arm 3222 adapts to the installation position of the negative terminal on the side wall of the battery 31, and the elastic pressure plate 32221 provided on the connecting arm 3222 ensures the tightness of the connection between the negative terminal connector 322 and the negative terminal of the battery 31, and ensures that the elastic pressure plate 32221 is always pressed against the negative terminal of the battery 31.

[0162] In some embodiments, the end of the third bracket 35 facing the opening 11 is provided with a first guide groove 353 and a second guide groove 354. The positive electrode connector 321 passes through the first guide groove 353 and abuts against the positive electrode of the battery 31, and the negative electrode connector 322 passes through the second guide groove 354 and abuts against the negative electrode of the battery 31.

[0163] In this embodiment, the first guide groove 353 and the second guide groove 354 can be second through groove structures 58 extending in a first direction at the end of the third bracket 35 facing the opening 11. The first guide groove 353 and the second guide groove 354 can be groove structures extending in a first direction on the sidewall of the end of the third bracket 35 facing the opening 11. This embodiment does not limit the specific type of groove. Thus, since the positive electrode connector 321 passes through the first guide groove 353 and abuts against the positive electrode connector 3221, and the negative electrode connector 322 passes through the second guide groove 354 and abuts against the negative electrode connector 3221, the positive electrode connector 3221 and the positive electrode of the battery 31 can be guided to abut against each other through the first guide groove 353, and the negative electrode connector 322 and the negative electrode of the battery 31 can be guided to abut against each other through the second guide groove 354.

[0164] As can be seen from the above embodiments, in this application embodiment, since the first end of the battery 31 is detachably connected to the third bracket 35, the second end of the battery 31 is detachably connected to the pen cap 5, the main board 32 is mounted on the third bracket 35, and the main board 32 is connected to a positive terminal connector 321 and a negative terminal connector 322. The positive terminal connector 321 abuts against the positive terminal of the battery 31, and the negative terminal connector 322 abuts against the negative terminal of the battery 31. Therefore, when it is necessary to replace the battery 31, the pen cap 5 can be removed from the opening 11 of the pen body 1, and then the first end of the battery 31 and the third bracket 35 can be separated. Finally, the second end of the battery 31 and the pen cap 5 can be separated, thus realizing the disassembly of the battery 31. When assembling the battery 31 into the electronic pen, the second end of the battery 31 can be connected to the pen cap 5 first, and then the second end of the battery 31 can be connected to the third bracket 35, so that the positive terminal connector 321 abuts against the positive terminal of the battery 31, and the negative terminal connector 322 abuts against the negative terminal of the battery 31. Then, the pen cap 5 is connected to the opening 11. In summary, the electronic pen provided in this embodiment facilitates the installation and removal of the battery 31, which helps to improve the battery life and extend the lifespan of the electronic pen.
