Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0029] As an input device, a stylus can be used to input information into some electronic devices. For example, text can be input on a mobile phone or drawing on an electronic drawing board. In order to improve the versatility of the stylus, a low-cost stylus is designed and manufactured. The low-cost stylus only includes a pen holder, a pen tip, a pen cap, and a circuit board installed in the pen holder. When using the stylus, a battery needs to be installed in the pen holder to power the stylus. Based on the principle of energy saving, the stylus is not equipped with a Bluetooth module or an interface that can be connected to other electronic devices.

[0030] If the firmware of the low-cost stylus needs to be upgraded, the pen holder can only be disassembled to expose the circuit board, because the circuit board in the stylus is fixedly encapsulated in the pen holder and there is no module or interface on the stylus that can be electrically connected to other electronic devices. This brings inconvenience to the research and development and after-sales service of the low-cost stylus.

[0031] The present application embodiment provides a stylus pen, which can easily and quickly complete the firmware upgrade of the stylus pen. Figure 1 , Figure 2 and Figure 3 , Figure 1 shows a schematic diagram of the exploded structure of the stylus provided by the present application, Figure 2 shows a schematic diagram of the structure of the stylus provided by the present application, Figure 3 The schematic diagram of a partial cross-section of a circuit board included in the stylus provided by the present application is shown. The stylus 1 comprises: a pen housing 11 and a circuit board 12; wherein the pen housing 11 has a receiving cavity 111; the circuit board 12 is installed in the receiving cavity 111, and a signal contact 121 is provided on the circuit board 12, and the signal contact 121 is located at a position on the circuit board 12 corresponding to the removable part; after the removable part is moved relative to the pen housing 11, the signal contact 121 is exposed, and the upgrade jig can be electrically connected to the signal contact 121 to transmit data.

[0032] In the embodiment of the present application, the pen housing 11 can provide an installation position for other parts of the stylus pen 1, so as to facilitate the assembly of other parts of the stylus pen 1. The pen housing 11 can also be used as a part held by the user when using the stylus pen 1, so as to facilitate the user to hold the stylus pen 1 in hand.

[0033] For example, Figure 3 As shown, the pen housing 11 can be configured as a cylindrical structure with a receiving cavity 111, such as configuring the pen housing 11 to be cylindrical, hexagonal cylindrical, etc. The embodiment of the present application does not limit the shape of the pen housing 11.

[0034] In the embodiment of the present application, the circuit board 12 can be used to set connecting wires, microcontroller unit (MCU) and application specific integrated circuit (ASIC) and other devices in the stylus 1, and the pen tip 16 can be electrically connected to the circuit board 12 to realize the handwriting input function of the stylus 1.

[0035] For example, Figure 2 and Figure 3 As shown, the circuit board 12 can be installed in the accommodating cavity 111 of the pen housing 11. At the same time, a signal contact 121 can be set on the circuit board 12, and the signal contact 121 is set at a position on the circuit board 12 corresponding to the removable part of the stylus 1 or other removable parts.

[0036] For example, when the tip 16 of the stylus pen 1 is detachable, the signal contact 121 can be set on the end of the circuit board 12 facing the tip 16; or, when the cap 15 of the stylus pen 1 is detachable, the signal contact 121 can be set on the end of the circuit board 12 facing the cap 15; alternatively, the signal contact 121 can be set on the circuit board 12 at a position adjacent to the power supply unit 2, and the power supply unit 2 can be a rechargeable battery or a disposable alkaline battery; a detachable or movable shielding member, such as a shielding sheet or a shielding ring, can also be set on the pen housing 11.

[0037] In this way, when the pen tip 16, the pen cap 15, the power supply 2 or the shielding member is removed from the pen housing 11, the signal contact 121 on the circuit board 12 located in the accommodating cavity 111 of the pen housing 11 can be exposed to the outside, and the upgrade jig can be directly abutted against the signal contact 121 to be electrically connected, or the signal contact 121 can be electrically connected to the upgrade jig through a wire, etc. In this way, the upgrade jig can be electrically connected to the circuit board 12 to realize data transmission between the upgrade jig and the circuit board 12, so that the firmware upgrade of the stylus 1 can be completed through the upgrade jig.

[0038] The stylus pen 1 provided in the embodiment of the present application has a receiving cavity 111 disposed on the pen housing 11, and the receiving cavity 111 can provide installation positions for other parts in the stylus pen 1. At the same time, a signal contact 121 is disposed on the circuit board 12 installed in the receiving cavity 111, and the signal contact 121 is located at a position on the circuit board 12 corresponding to the removable part, so that after the removable part is removed from the pen housing 11 or the position of the removable part on the pen housing 11 is moved, the signal contact 121 on the circuit board 12 can be exposed to the outside, so that it is convenient to electrically connect the upgrade jig with the signal contact 121 on the circuit board 12, that is, the appearance of the stylus pen is not damaged, and the stylus pen can be easily upgraded through an external upgrade jig.

[0039] In some possible embodiments of the present application, along the axial direction A of the pen housing 11 , one end of the accommodating cavity 111 has an opening 112 , and the signal contact 121 is arranged on a side of the opening 112 of the accommodating cavity 111 on the circuit board 12 .

[0040] In the present application embodiment, Figure 1 and Figure 3 As shown, an opening 112 may be provided at one end of the accommodating cavity 111 of the pen housing 11 , so as to facilitate installation of the power supply element 2 for power supply in the pen housing 11 .

[0041] For example, Figure 3 As shown, in the axial direction A of the pen housing 11, the signal contact 121 can be arranged on one side of the circuit board 12, that is, the signal contact 121 can be arranged on the side of the circuit board 12 facing the opening 112 of the accommodating cavity 111. In this way, after the battery as the power supply unit 2 is removed from the accommodating cavity 111, the signal contact 121 on the circuit board 12 can be exposed.

[0042] In the above embodiment, since an opening 112 is provided at one end of the accommodating cavity 111 of the pen housing 11, it is convenient to install the power supply unit 2 and the like in the pen housing 11 through the opening 112. In addition, the signal contact 121 is provided on the side of the circuit board 12 facing the opening 112 of the accommodating cavity 111, and when the opening 112 of the accommodating cavity 111 is opened, the signal contact 121 can be exposed to the outside through the opening 112 of the accommodating cavity 111.

[0043] In some possible embodiments of the present application, the signal contact 121 on the circuit board 12 includes a plurality of contact grooves distributed along the radial direction R of the pen housing 11 .

[0044] In the present application embodiment, Figure 3 As shown, the signal contact 121 on the circuit board 12 can be set in the form of a groove structure, and the groove is electrically connected to the electronic device on the circuit board 12.

[0045] Exemplarily, in the radial direction R of the pen housing 11, that is, in the width direction of the circuit board 12, a plurality of grooves may be provided on the side of the circuit board 12. For example, four grooves are provided on the side of the opening 112 of the circuit board 12 facing the accommodating cavity 111, and the four grooves are spaced and distributed on the side of the circuit board 12. The grooves may be provided in a shape with a cross section approximately in a semicircular shape, or in a shape approximately in a conical shape, etc., and a conductive member may be provided in each groove, such as covering each groove with a layer of copper sheet, and the copper sheet is electrically connected to the corresponding electronic device on the circuit board 12, so as to form a signal contact 121 on the circuit board 12. Two or other number of contact grooves may also be provided on the side of the circuit board 12, and the embodiment of the present application does not limit the number of contact grooves.

[0046] In the above embodiment, since the signal contact 121 is arranged on the circuit board 12 along the radial direction R of the pen housing 11, the width of the circuit board 12 can be utilized to arrange a plurality of contact grooves as the signal contact 121 on the circuit board 12. At the same time, the signal contact 121 is arranged in the structural form of the contact groove, which can increase the surface area of ​​the contact groove. In the process of abutting the upgrade jig with the contact groove, it is convenient to make the plurality of signal transmission parts on the upgrade jig abut with each corresponding contact groove, which is conducive to improving the stability of the electrical connection between the upgrade jig and the contact groove.

[0047] In some possible embodiments of the present application, refer to Figure 4 , Figure 4 The circuit board 12 has a power contact 122 adjacent to the signal contact 121 , and the power contact 122 is used to be electrically connected to the power supply 2 to provide power to the stylus 1 .

[0048] In the present application embodiment, Figure 3 and Figure 4 As shown, a power contact 122 can be set on the circuit board 12 at a position adjacent to the signal contact 121. The power contact 122 is electrically connected to other electronic components on the circuit board 12 through a wire, so that the power supply 2 accommodated in the accommodating cavity 111 abuts against the power contact 122 to supply power to the stylus 1.

[0049] Exemplarily, in the axial direction A of the pen housing 11, a power contact 122 may be provided on the side of the opening 112 of the accommodating cavity 111 of the pen housing 11 on the circuit board 12. For example, in the radial direction R of the pen housing 11, the power contact 122 may be located in the middle of the side of the circuit board 12, and the power contact 122 and the signal contact 121 may be spaced apart and distributed on the circuit board 12. The power contact 122 may be made of an elastic material having conductivity, such as providing the power contact 122 as a strip structure capable of generating deformation, one end or both ends of the strip structure being electrically connected to the circuit board 12, and the middle part of the strip structure may generate a certain deformation under the pressure of the power supply unit 2, so that the power contact 122 and the power supply unit 2 have sufficient abutment force.

[0050] In the above embodiment, since the power contact 122 is provided at a position adjacent to the signal contact 121 on the circuit board 12, the power supply element 2 can be electrically connected to the circuit board 12 through the power contact 122, so as to power the stylus 1. At the same time, since the power contact 122 is adjacent to the signal contact 121, when the signal transmission element on the upgrade jig is abutted against the signal contact 121, the power supply connection element on the upgrade jig can also be abutted against the power contact 122. In this way, in the process of realizing data transmission between the upgrade jig and the stylus 1 through the signal contact 121, the stylus 1 can also be powered by the upgrade jig.

[0051] In some possible embodiments of the present application, the stylus pen 1 further includes a cover 13, which is detachably mounted at the opening 112 of the accommodating cavity 111, and the power supply 2 can be accommodated between the cover 13 and the circuit board 12; when the cover 13 and the power supply 2 are removed, the signal contact 121 is exposed.

[0052] In the present application embodiment, Figure 1 As shown, a cover 13 can be provided in the stylus pen 1 , and the cover 13 is arranged to match the position of the opening 112 of the accommodating cavity 111 of the pen housing 11 , so that the cover 13 can be installed on the opening 112 of the accommodating cavity 111 , thereby fixing the power supply unit 2 in the stylus pen 1 .

[0053] Exemplarily, an internal thread may be provided on the inner wall of the opening 112 of the accommodating cavity 111, and an external thread matching the internal thread may be provided on the cover body 13, so that the cover body 13 and the pen housing 11 are detachably connected by threaded connection. At the same time, the accommodating cavity 111 of the pen housing 11 may have enough space to accommodate the power supply component 2 such as a battery in the accommodating cavity 111 of the pen housing 11. A pen cap 15 may also be provided on the end of the cover body 13 away from the pen housing 11, and the pen cap 15 and the cover body 13 may be detachably connected by a snap-fit ​​or an interference fit. In this way, after the cover body 13 is removed from the pen housing 11, the power supply component 2 is taken out of the accommodating cavity 111, so that the signal contacts 121 on the circuit board 12 can be exposed to the outside.

[0054] In the above embodiment, since the cover 13 is provided in the stylus pen 1 , the cover 13 can be covered on the opening 112 of the accommodating cavity 111 of the pen housing 11 , so as to fix the power supply unit 2 in the accommodating cavity 111 .

[0055] In some possible embodiments of the present application, refer to Figure 5 , Figure 5 The schematic diagram of the axial structure of the stylus provided by the present application is shown. The stylus 1 provided by the embodiment of the present application further includes a fixing member 14, which is arranged between the circuit board 12 and the pen housing 11, and is used to provide support for the circuit board 12 so as to fix the circuit board 12 in the accommodating cavity 111; a limiting portion 141 is arranged at a position corresponding to the signal contact 121 on the fixing member 14, and when the upgrade jig is inserted into the accommodating cavity 111 and electrically connected to the signal contact 121, the limiting portion 141 is used to limit the position of the upgrade jig relative to the circuit board 12.

[0056] In the present application embodiment, Figure 3 , Figure 4 and Figure 5 As shown, a fixing member 14 may be provided in the stylus pen 1 , so that the circuit board 12 is fixedly mounted in the accommodating cavity 111 of the pen housing 11 through the fixing member 14 .

[0057] Exemplarily, the fixing member 14 can be configured to have a structure including two semi-cylinders, which clamp the circuit board 12 in the middle to form a cylinder that matches the accommodating cavity 111 of the pen housing 11. The fixing member 14 can then be inserted into the accommodating cavity 111 at one end close to the pen tip 16 to fix the circuit board 12 in the accommodating cavity 111.

[0058] As another example, a limiting portion 141 may be provided on the fixing member 14 to limit the position of the upgrade jig relative to the circuit board 12 through the limiting portion 141, so that the upgrade jig is accurately connected to the signal contact 121 on the circuit board 12 to achieve a foolproof design. For example, a groove or a blind hole may be provided on one end of the fixing member 14 close to the signal contact 121, and the groove or the blind hole may be used as the limiting portion 141 on the fixing member 14. Correspondingly, a protrusion matching the notch or the blind hole may be provided on the upgrade jig. In this way, in the process of inserting the upgrade jig into the accommodating cavity 111 of the pen housing 11, only when the protrusion is aligned with the notch or the blind hole, can the signal transmission member on the upgrade jig be close to the signal contact 121 on the circuit board 12 and abut against the signal contact 121.

[0059] Another example, such as Figure 3 and Figure 4 As shown, in the axial direction A along the pen housing 11, the fixing member 14 can be set to be longer than the circuit board 12, that is, the end of the fixing member 14 is closer to the opening 112 of the accommodating cavity 111 than the end of the circuit board 12. In this way, the circuit board 12 can be protected by the fixing member 14, which is conducive to reducing the risk of foreign matter falling between the signal contacts 121 and causing a short circuit in the circuit board 12.

[0060] In the above embodiment, since the fixing member 14 is provided in the stylus pen 1, the circuit board 12 can be fixedly installed in the accommodating cavity 111 of the pen housing 11 through the fixing member 14. At the same time, a limiting portion 141 is provided on the fixing member 14, and the position of the upgrade jig relative to the circuit board 12 can be limited by the limiting portion 141, thereby reducing the risk of connecting the upgrade jig to the signal contact 121 on the circuit board 12 in an incorrect manner.

[0061] In some possible embodiments of the present application, the limiting portion 141 on the fixing member 14 includes a limiting notch extending along the axial direction A of the pen housing 11 .

[0062] In the present application embodiment, Figure 4 and Figure 5 As shown, the limiting portion 141 on the fixing member 14 can be set to a limiting notch structure. For example, the limiting notch can be set on the circumferential side surface of the fixing member 14 adjacent to the inner wall of the accommodating cavity 111 of the pen housing 11; that is, in the axial direction A along the pen housing 11, the limiting notch extends from the side surface of the fixing member 14 close to the opening 112 of the accommodating cavity 111 to a direction away from the opening 112.

[0063] In the above embodiment, since the limiting portion 141 on the fixing member 14 is set to a limiting notch structure, not only can the position of the upgrading fixture relative to the circuit board 12 be limited by the limiting notch, but the limiting notch does not occupy the space in the accommodating cavity 111, and thus will not affect the installation of the power supply unit 2 and the like in the stylus 1.

[0064] In addition, the present application embodiment also provides a stylus assembly, referring to Figure 6 , Figure 6 The structural schematic diagram of the upgrade jig of the stylus assembly provided by the present application is shown. The stylus assembly comprises: an upgrade jig 3 and a stylus 1 provided by any one of the above embodiments; wherein the upgrade jig 3 is adapted to the accommodating cavity 111 on the pen shell 11 of the stylus 1, and along the axial direction A of the upgrade jig 3, one end of the upgrade jig 3 is provided with a signal transmission member 31 corresponding to the signal contact 121 on the circuit board 12 of the stylus 1, and the upgrade jig 3 is inserted into the accommodating cavity 111, and the signal transmission member 31 can abut against the signal contact 121; the upgrade jig 3 can be electrically connected to the electronic device.

[0065] In the embodiment of the present application, an upgrade jig 3 matching the stylus 1 may be provided in the stylus assembly, so as to electrically connect the upgrade jig 3 to the signal contact 121 on the circuit board 12 , thereby completing the firmware upgrade of the stylus 1 .

[0066] For example, Figure 6 As shown, the upgrade jig 3 can be set to a structural form that matches the accommodating cavity 111 on the pen housing 11. For example, at least a portion of the upgrade jig 3 can be set to a cylindrical shape that matches the accommodating cavity 111, so that the upgrade jig 3 can be inserted into the accommodating cavity 111 of the pen housing 11.

[0067] In another example, a signal transmission member 31 may be provided at one end of the upgrade jig 3 that can be inserted into the accommodating cavity 111, and the signal transmission member 31 corresponds to the signal contact 121 on the circuit board 12. For example, the signal transmission member 31 may be a spring pin. For another example, in the case where there are four signal contacts 121 on the circuit board 12, four spring pins may be provided on the upgrade jig 3. In this way, after the upgrade jig 3 is inserted into the accommodating cavity 111 of the pen housing 11, the four spring pins may respectively contact with the four signal contacts 121 in a one-to-one correspondence.

[0068] In another example, a wire may be provided at one end of the upgrade jig 3 away from the signal transmission member 31, or a wireless connection device such as a Bluetooth module may be provided in the upgrade jig 3. In this way, the upgrade jig 3 may be electrically connected to an electronic device such as a computer in a wired or wireless manner, so that data may be transmitted between the circuit board 12 of the stylus pen 1 and the computer through the upgrade jig 3.

[0069] The stylus pen assembly provided in the embodiment of the present application includes an upgrade jig 3 adapted to the stylus pen 1, and a signal transmission component 31 corresponding to the signal contact 121 on the circuit board 12 of the stylus pen 1 is provided on the upgrade jig 3. The signal transmission component 31 can be abutted against the signal contact 121, so that the upgrade jig 3 and the circuit board 12 can be electrically connected, and then the electronic device can be electrically connected to the circuit board 12 through the upgrade jig 3, so as to facilitate operations such as upgrading the firmware of the stylus pen 1.

[0070] In some possible embodiments of the present application, a guide portion 33 is provided on the upgrade jig 3 at a position corresponding to the signal transmission component 31 , and the guide portion 33 is matched with the limiting portion 141 in the stylus pen 1 .

[0071] In the present application embodiment, Figure 6 As shown, a guide portion 33 may be provided at one end of the signal transmission member 31 on the upgrade jig 3, and the guide portion 33 may be provided as a structure matching the position limiting portion 141 on the fixing member 14 in the stylus pen 1. For example, in the case where the position limiting portion 141 is a position limiting notch, the guide portion 33 may be provided as a protrusion matching the position limiting notch, and the protrusion may be extended from a position on the end surface of the upgrade jig 3 close to the circumferential side wall of the upgrade jig 3 along the axial direction A of the upgrade jig 3. In this way, after the upgrade jig 3 is inserted into the accommodating cavity 111 in the pen shell 11 of the stylus pen 1, the upgrade jig 3 may be fully inserted into the accommodating cavity 111 only when the guide portion 33 is directly opposite to the position limiting portion 141, so that the signal transmission member 31 abuts against the signal contact 121.

[0072] In the above embodiment, since a guide portion 33 matching the limiting portion 141 on the fixing member 14 in the stylus 1 is provided on the upgrade jig 3, the insertion angle of the upgrade jig 3 in the accommodating cavity 111 can be guided by the guide portion 33 so as to accurately electrically connect the signal transmission member 31 with the signal contact 121.

[0073] In some possible embodiments of the present application, a power supply connector 32 is further provided at a position on the upgrade jig 3 corresponding to the signal transmission component 31 , and the power supply connector 32 corresponds to the power contact 122 in the stylus 1 .

[0074] In the present application embodiment, Figure 6 As shown, a power supply connector 32 may be provided on the upgrade jig 3 , so as to power the stylus pen 1 through the upgrade jig 3 during the firmware upgrade of the stylus pen 1 .

[0075] Exemplarily, a power supply connector 32 may be provided on the upgrade jig 3 at a position adjacent to the signal transmission member 31. For example, along the axial direction A of the upgrade jig 3, the power supply connector 32 may be provided at the center of the axial end surface of the upgrade jig 3, that is, the power supply connector 32 is located at a position on the upgrade jig 3 corresponding to the power contact 122 on the circuit board 12. The power supply connector 32 may be a conductive member such as a spring pin.

[0076] In the above embodiment, since a power supply connector 32 corresponding to the power supply contact 122 in the stylus pen 1 is provided on the upgrade jig 3, after the upgrade jig 3 is inserted into the accommodating cavity 111 of the pen shell 11 of the stylus pen 1, the power supply connector 32 can be brought into contact with the power supply contact 122, so that the upgrade jig 3 can provide electrical energy to the stylus pen 1.
