[0024] Example Please refer to the following: Figure 1 and Figure 2 This embodiment provides an electronic pen, including a pen body 100, a motherboard 200, and a sealing element 300.

[0025] The pen body 100 includes a pen body main body 110 and a filler 120. The pen body main body 110 has a first through hole 111, and the filler 120 is connected to the pen body main body 110 through the first through hole 111. The pen body main body 110 and the filler 120 together form a receiving cavity 130.

[0026] Both the main board 200 and the seal 300 are disposed within the receiving cavity 130. The main board 200 is provided with a conductive part 210. The seal 300 covers the main board 200 and is provided with a second through hole 310.

[0027] The conductive part 210 includes a conductive contact 211, which corresponds to the second through hole 310 along the radial direction of the pen body 110. At least a portion of the conductive contact 211 corresponds to the first through hole 111 along the radial direction of the pen body 110. The conductive contact 211 can be the entire conductive part 210 or a portion of the conductive part 210; this is not limited here.

[0028] Optionally, the number of second through holes 310 is the same as the number of conductive parts 210. When there are multiple conductive parts 210, there are also multiple second through holes 310. One conductive part 210 corresponds to one second through hole 310, and each conductive part 210 includes a conductive contact 211. Each conductive contact 211 corresponds to a second through hole 310 along the radial direction of the pen body 110, and at least a portion of all conductive contacts 211 corresponds to a first through hole 111 along the radial direction of the pen body 110.

[0029] Understandably, the correspondence between the conductive contact 211 and the second through hole 310 along the radial direction of the pen body 110 specifically means that the conductive contact 211 and the second through hole 310 overlap in the radial direction of the pen body 110.

[0030] Furthermore, the correspondence between at least a portion of the conductive contact 211 and the first through hole 111 along the radial direction of the pen body 110 specifically means that the conductive contact 211 and the first through hole 111 have an overlapping area in the radial direction of the pen body 110. This can be because the projection of the conductive contact 211 along the radial direction of the pen body 110 onto any plane falls within the projection range of the first through hole 111 along the radial direction of the pen body 110 onto that plane (e.g., ...). Figure 3 (As shown), or the projection of the conductive contact 211 along the radial direction of the pen body 110 onto any plane overlaps with the projection of the first through hole 111 along the radial direction of the pen body 110 onto any plane (e.g.) Figure 4 (As shown).

[0031] In the aforementioned electronic pen, since the conductive contacts 211 of the conductive part 210 correspond to the second through hole 310 along the radial direction of the pen body 110, and at least a portion of the conductive contacts 211 correspond to the first through hole 111 along the radial direction of the pen body 110, after removing the filler 120 from the first through hole 111, probes or other tools can be inserted into the receiving cavity 130 and contact the conductive contacts 211, making the probe electrically connected to the motherboard 200, thereby performing a software upgrade on the motherboard 200. The upgrade process is simple and does not require disassembling the pen body 110 and components such as the motherboard 200 in the receiving cavity 130. After the upgrade is completed, the filler 120 can be reinstalled in the first through hole 111, ensuring the integrity of the electronic pen's appearance and preventing foreign objects from entering the receiving cavity 130. The sealing element 300, which is installed in the receiving cavity 130, covers the main board 200 and can seal the part of the main board 200 except for the conductive part 210, to isolate water, oxygen and other impurities, and ensure the long-term stable operation of the main board 200.

[0032] For example, the filler 120 may be in an interference fit with the wall of the first through hole 111, or the filler 120 may be magnetically attracted to the pen body 110 or other components within the pen body 110, thereby enabling the filler 120 to be easily and quickly removed from the first through hole 111 and reinstalled.

[0033] For example, motherboard 200 is a PCBA (Printed Circuit Board Assembly) motherboard.

[0034] For example, the seal 300 is made of silicone.

[0035] Please refer to the following: Figure 3 and Figure 4 In some embodiments, the conductive contact 211 is located on the side of the second through hole 310 away from the first through hole 111.

[0036] Please see Figure 5In some embodiments, the conductive contact 211 is inserted into the second through hole 310. In this case, the length of the conductive contact 211 is less than or equal to the length of the second through hole 310.

[0037] Please see Figure 6 In some other embodiments, the conductive contact 211 passes through the second through hole 310, and the end of the conductive contact 211 away from the motherboard 200 is located on the side of the second through hole 310 facing the first through hole 111. In this case, the length of the conductive contact 211 is greater than the length of the second through hole 310.

[0038] Please refer to it again. Figure 1 In some embodiments, the electronic pen further includes a pen tip 400. The pen tip 400 is disposed at one end of the pen body 110 along the axial direction and is electrically connected to the motherboard 200.

[0039] When in use, the pen tip 400 works in conjunction with the touch terminal, and the touch terminal senses the touch of the pen tip 400 to trigger the corresponding operation command.

[0040] In some embodiments, the electronic pen further includes a first bracket 500. The first bracket 500 is disposed within the receiving cavity 130, and the sealing member 300 is engaged with the first bracket 500.

[0041] When assembling the above-mentioned electronic pen, first snap the seal 300 with the first bracket 500, use the first bracket 500 to limit and fix the seal 300, and then install the first bracket 500 in the receiving cavity 130.

[0042] Please combine Figure 7 and Figure 8 The sealing element 300 engages with the first bracket 500. This can be achieved by having a first groove 510 on the first bracket 500 and a corresponding first engaging portion 320 on the sealing element 300, with the first engaging portion 320 embedded in the first groove 510. Alternatively, a second groove 330 can be provided on the sealing element 300, and a corresponding second engaging portion 520 can be provided on the first bracket 500, with the second engaging portion 520 embedded in the second groove 330. Furthermore, both the first groove 510 and the second engaging portion 520 can be provided on the first bracket 500, and the first engaging portion 320 and the second groove 330 can be correspondingly provided on the sealing element 300.

[0043] For example, the first bracket 500 is provided with two sets of first grooves 510, which are arranged side by side. Each set of first grooves 510 includes three first grooves 510, and the three first grooves 510 in the same set are arranged at intervals along the axial direction of the pen body 110. In addition, the first bracket 500 is also provided with two second latching parts 520, which are arranged at intervals along the axial direction of the pen body 110.

[0044] Accordingly, the seal 300 is provided with two sets of first snap-fit ​​portions 320 and two second grooves 330.

[0045] During assembly, the seal 300 is engaged with the first bracket 500 along the radial direction of the pen body 110, so that the first engaging part 320 on the seal 300 is embedded in the corresponding first groove 510 on the first bracket 500, and at the same time, the second engaging part 520 on the first bracket 500 is embedded in the corresponding second groove 330 on the seal 300, so that the seal 300 and the first bracket 500 are mutually limited and kept relatively fixed.

[0046] Subsequently, the first bracket 500 and the sealing element 300 on the first bracket 500 are installed together in the receiving cavity 130. The first bracket 500 cooperates with the pen body 110 and clamps and fixes the sealing element 300 along the radial direction of the pen body 110, thereby achieving full fixation of the sealing element 300.

[0047] Please refer to the following: Figure 1 and Figure 9 Furthermore, in some embodiments, the electronic pen further includes a second support 600. The first support 500, the main board 200, and the second support 600 are stacked radially along the pen body 110. The first support 500 cooperates with the second support 600 to clamp and fix the main board 200 and protect the main board 200.

[0048] Optionally, the motherboard 200 is mounted on the second bracket 600 and is snapped together with the second bracket 600.

[0049] When assembling the electronic pen, the mainboard 200 is first installed onto the second bracket 600, then the first bracket 500 is assembled, and a sealing element 300 is installed on the first bracket 500 to form the pen refill assembly. The pen refill assembly is then inserted into the receiving cavity 130 along the axial direction of the pen body 110 from the end of the pen body 110 away from the pen tip 400. At this time, the first bracket 500 and the pen body 110 are interference-fitted or bonded, and the second bracket 600 and the pen body 110 are also interference-fitted, thereby fixing the entire pen refill assembly.

[0050] Please refer to the following: Figure 8 and Figure 10In some embodiments, the seal 300 includes a first sealing portion 340. The first sealing portion 340 is disposed on the main board 200, and a second through hole 310 is provided on the first sealing portion 340.

[0051] In use, the first sealing part 340 can seal the area on the motherboard 200 around the conductive part 210. When the conductive part 210 is exposed, water, oxygen and other impurities are prevented from entering the motherboard 200 from the vicinity of the conductive part 210, which helps to ensure the long-term operation of the motherboard 200.

[0052] Furthermore, in some embodiments, the first sealing portion 340 is provided with a first protrusion 350 on the side facing the motherboard 200, and the first protrusion 350 is arranged around the second through hole 310.

[0053] When the first sealing part 340 covers the motherboard 200, the pressure is concentrated on the first protrusion 350. The first protrusion 350 deforms under pressure and fits tightly against the surface of the motherboard 200, which enhances the sealing effect. On this basis, by arranging the first protrusion 350 around the second through hole 310, the conductive part 210 can be better isolated from the surrounding area, thereby more effectively preventing water, oxygen and other impurities from entering the motherboard 200 from the vicinity of the conductive part 210.

[0054] The first protrusion 350 may be configured to correspond one-to-one with the second through hole 310, with each second through hole 310 surrounded by a first protrusion 350. Alternatively, the first protrusion 350 may surround multiple adjacent second through holes 310, and this embodiment does not limit this.

[0055] In addition, the first protrusion 350 is made of silicone and is integrally formed with the first sealing part 340.

[0056] In some embodiments, at least two sets of second through holes 310 are provided. Each set contains multiple second through holes 310, and the multiple second through holes 310 are arranged in an array.

[0057] When the motherboard 200 is upgraded with software, the conductive parts 210 exposed from the multiple second through holes 310 can all contact the probe, ensuring a stable connection between the probe and the motherboard 200. One set of conductive parts 210 exposed within the second through holes 310 serves as the positive terminal interface, and the other set serves as the negative terminal interface. Furthermore, when the multiple second through holes 310 in each set are arranged in an array, the corresponding conductive parts 210 are also arranged in an array, providing a better fit for the probe.

[0058] For example, the second through hole 310 is provided in two groups, with four second through holes 310 in each group, and the four second through holes 310 in the same group are arranged in a rectangular array.

[0059] Accordingly, there are two first protrusions 350. The two first protrusions 350 correspond to two sets of second through holes 310 respectively, and the first protrusions 350 surround the corresponding set of second through holes 310.

[0060] It should be noted that the second through hole 310 can be a circular hole, a square hole, or any other shape; this embodiment does not limit this.

[0061] Understandably, the seal 300 may completely enclose the motherboard 200, exposing only the conductive part 210 and the necessary circuit interfaces (such as the interface between the motherboard 200 and the pen tip 400), thus completely sealing the motherboard 200.

[0062] Alternatively, please refer to the following: Figure 7 and Figure 10 In some embodiments, the seal 300 includes a second sealing portion 360. The second sealing portion 360 is fitted to the inner wall of the pen body 110, and a second protrusion 370 is provided on the side of the second sealing portion 360 facing the pen body 110, the second protrusion 370 being arranged around the first through hole 111.

[0063] At this time, the seal 300 seals both the main board 200 and the area on the pen body 110 where the first through hole 111 is located. When water, oxygen, and other impurities enter the receiving cavity 130 through the first through hole 111 on the pen body 110, they can only contact the seal 300 and the conductive part 210, and remain isolated from the parts of the main board 200 other than the conductive part 210 and other structures within the receiving cavity 130.

[0064] Specifically, when the second sealing part 360 is in contact with the inner wall of the pen body 110, the pressure is concentrated on the second protrusion 370. The second protrusion 370 deforms under pressure and fits tightly against the inner wall of the pen body 110, which enhances the sealing effect. On this basis, by arranging the second protrusion 370 around the first through hole 111, it is possible to better prevent water, oxygen and other impurities from entering other areas of the receiving cavity 130 through the space between the second sealing part 360 and the inner wall of the pen body 110.

[0065] Similarly, the second protrusion 370 is made of silicone and is integrally molded with the second sealing part 360.

[0066] Furthermore, in some embodiments, at least two second protrusions 370 are provided, and the distance between the at least two second protrusions 370 and the first through hole 111 increases sequentially.

[0067] That is to say, along the direction away from the first through hole 111, at least two second protrusions 370 are arranged sequentially from the inside to the outside.

[0068] At least two second protrusions 370 are provided to form a multi-layer barrier against water, oxygen, and other impurities. When a portion of the second protrusions 370 fails to seal, the remaining second protrusions 370 can still provide sufficient sealing to prevent water, oxygen, and other impurities from entering other areas of the receiving cavity 130 through the space between the second sealing part 360 and the inner wall of the pen body 110.

[0069] For example, there are two second protrusions 370, and the two second protrusions 370 have the same or similar shapes.

[0070] Please see Figure 10 In some embodiments, the first through hole 111 is a button hole, the filler 120 is a button, and the button is pressably disposed in the first through hole 111.

[0071] Understandably, the main body 110 of an electronic pen typically has a button hole. Utilizing this button hole as a first through-hole 111 allows for software upgrades and updates to the motherboard 200, making full use of the button hole and simplifying the overall structure of the electronic pen. In this case, the pressable filler 120 within the first through-hole 111 also functions as a button.

[0072] Correspondingly, a switch 220 is provided on the motherboard 200, and the switch 220 corresponds to the button.

[0073] By pressing, the filler 120 triggers the switch 220, which turns the electronic pen on or off, or performs other operations.

[0074] For example, the filler 120 includes a pressing part 121, a trigger part 122 and a snap-fit ​​part 123, with the trigger part 122 and the snap-fit ​​part 123 respectively connected to the pressing part 121.

[0075] The pressing part 121 is slidably disposed within the first through hole 111 along the radial direction of the pen body 110. When not pressed, the top end of the pressing part 121 protrudes from the outer surface of the pen body 110. During use, the user directly contacts and presses the pressing part 121.

[0076] The trigger part 122 is connected to the side of the pressing part 121 facing the switch 220, and the trigger part 122 is aligned with the switch 220 along the radial direction of the pen body 110. When the user presses the pressing part 121, the trigger part 122 presses against the switch 220 along the radial direction of the pen body 110, thereby triggering the switch 220.

[0077] Two latching parts 123 are provided, and the two latching parts 123 are respectively connected to the two ends of the pressing part 121 along the axial direction of the pen body 110. In addition, the latching parts 123 are bent to facilitate their own elastic deformation.

[0078] When the filler 120 is installed, the ends of the two latching parts 123 away from the pressing part 121 respectively abut against the wall of the first through hole 111, and after receiving the reaction force from the wall of the first through hole 111, they bend and deform inward until the latching parts 123 completely pass through the first through hole 111 and enter the receiving cavity 130. Subsequently, the latching parts 123 return to their original shape, thereby hooking onto the inner wall of the pen body 110, making it difficult for the entire filler 120 to fall out of the first through hole 111 on its own.

[0079] When upgrading the motherboard 200 with software, simply remove the filler 120 and reinstall it after the upgrade is complete. The operation is simple.

[0080] Furthermore, in some embodiments, the seal 300 includes a third sealing portion 380. The third sealing portion 380 covers the switch 220, and the filler 120 presses against the switch 220 through the third sealing portion 380 when pressed.

[0081] When in use, the third sealing part 380 can seal and protect the switch 220, preventing water, oxygen and other impurities from entering the switch 220 and causing corrosion or jamming, which is conducive to the long-term stable operation of the switch 220.

[0082] In summary, in the aforementioned electronic pen, since the conductive contacts 211 of the conductive part 210 correspond to the second through hole 310 along the radial direction of the pen body 110, and at least a portion of the conductive contacts 211 correspond to the first through hole 111 along the radial direction of the pen body 110, after removing the filler 120 from the first through hole 111, probes or other tools can be inserted into the receiving cavity 130 and contact the conductive contacts 211, making the probe electrically connected to the motherboard 200, thereby performing a software upgrade on the motherboard 200. The upgrade process is simple and does not require disassembling the pen body 110 or the motherboard 200 and other components in the receiving cavity 130. After the upgrade is completed, the original filler 120 or a new filler 120 can be reinstalled in the first through hole 111, ensuring the integrity of the electronic pen's appearance and preventing foreign objects from entering the receiving cavity 130.
