Description
Technical Field
[0001] This application relates to the field of electronic terminals, and more specifically, to styluses, stylus assembly apparatus and methods, and electronic device components. Background Technology
[0002] Some known styluses have cracks on the outer circumference of their holders. Summary of the Invention
[0003] This application provides a stylus, a stylus assembly apparatus and method, and an electronic device component to address the problem of cracks appearing on the outer periphery of the known stylus holder.
[0004] In a first aspect, embodiments of this application provide a stylus including a pen holder and a refill assembly. The inner circumferential surface of the pen holder defines an internal space extending in a first direction; the pen holder has a limiting boss protruding from the inner circumferential surface. The refill assembly is mounted in the internal space and has a top abutment; the top abutment is circumferentially offset from the limiting boss.
[0005] In the embodiments of this application, the stylus is assembled by first inserting the pen refill assembly into the internal space until the limiting boss abuts against the top along the first direction, thus positioning the pen refill assembly and the pen barrel along the first direction (i.e., axial direction) and ensuring that the pen refill assembly and the pen barrel maintain their axial relative positions. Then, the pen refill assembly and the pen barrel are rotated relative to each other by a certain angle, causing the top and the limiting boss to be circumferentially offset, and the pen refill assembly and the pen barrel are fixed to each other in this offset state. The stylus obtained in this way has accurate axial positioning between the pen refill assembly and the pen barrel, and the pen barrel can freely expand and contract along the first direction when its length changes due to thermal expansion and contraction, thereby reducing the possibility of cracks and breakage in the pen barrel.
[0006] In one possible implementation, the limiting boss has a stepped surface facing the top in a first direction. The top has a top surface facing the limiting boss in the first direction. The top surface and the stepped surface are located in the same plane perpendicular to the first direction.
[0007] This ensures that the axial relative position of the pen tip assembly and the pen barrel of the assembled stylus remains consistent with the positioning state of the pen tip assembly relative to the pen barrel before rotation.
[0008] In one possible implementation, the limiting boss is an arc-shaped ring extending circumferentially, and the circumferential extension angle of the limiting boss is less than or equal to 180°; a notch is defined between the two circumferential ends of the limiting boss. The abutment is an arc-shaped ring extending circumferentially, and the circumferential extension angle of the abutment is less than or equal to 180°; a clearance space is defined between the two circumferential ends of the abutment. The projection of the abutment along a first direction is located within the notch, and the projection of the limiting boss along the first direction is located within the clearance space.
[0009] Thus, in a low-temperature environment, when the pen holder contracts along the first direction, the limiting protrusion of the pen holder can enter the clearance space along the first direction, while the top of the pen refill assembly can be accommodated in the notch, preventing the pen holder from being stretched and cracked due to being limited by the pen refill assembly.
[0010] In one possible implementation, the pen refill assembly is configured to extend in a first direction to a position where the abutment abuts against the limiting boss, and then rotate relative to the pen barrel to a state where the abutment and the limiting boss are circumferentially misaligned.
[0011] In this embodiment, the pen refill assembly is easy to install by rotating it after inserting it in the first direction, and the assembled stylus is less likely to crack due to the pen holder expanding or contracting.
[0012] In one possible implementation, there is one limiting boss and one abutment; or, there are multiple limiting bosses, which are spaced apart circumferentially; there are multiple abutments, which are spaced apart circumferentially; and during assembly, the multiple abutments and the multiple limiting bosses can abut against each other in a one-to-one correspondence along the first direction, and then rotate relative to each other circumferentially until they are relatively misaligned.
[0013] In this embodiment, one or more limiting bosses can achieve axial positioning of the pen holder and pen refill assembly.
[0014] In one possible implementation, the internal space of the pen holder has an insertion port at one end along a first direction, the insertion port being used to allow the pen refill assembly to be inserted into the internal space. A limiting boss is provided at the end of the pen holder along the first direction near the insertion port, or at the end of the pen holder along the first direction away from the insertion port, or at the middle position of the pen holder along the first direction.
[0015] In this embodiment, the position of the limiting boss can be set as needed.
[0016] In one possible implementation, the end face of the pen holder near the insertion port is provided with a first positioning mark and a second positioning mark spaced circumferentially; the end of the pen refill assembly near the insertion port is provided with a third positioning mark. When the third positioning mark and the first positioning mark are radially aligned, the abutment and the limiting boss are aligned in a first direction; and when the third positioning mark and the second positioning mark are radially aligned, the abutment and the limiting boss are circumferentially offset.
[0017] This allows for easy identification of the circumferential relative positions of the pen refill assembly and the pen holder, ensuring that during assembly, the pen refill assembly and the pen holder are accurately positioned axially and completely offset from each other after relative rotation.
[0018] In one possible implementation, the pen refill assembly includes a front section, a middle section, and a rear section of the pen refill connected sequentially along a first direction. A top abutment is located at the front section, and a clamping portion is provided at the end of the rear section away from the front section, for clamping and driving the entire pen refill assembly to rotate.
[0019] In this embodiment, the pen refill front section is provided at the top, the pen refill assembly and pen barrel are reliably positioned axially, and the clamping part is convenient for clamping and rotation.
[0020] In one possible implementation, the rear section of the pen refill includes a battery casing and a battery, with the battery housed in the battery casing and a clamping portion located at the end of the battery casing away from the front section of the pen refill.
[0021] In this embodiment, the clamping part is located at the end of the battery tube away from the front of the pen refill, so that it can be clamped and drive the pen refill assembly to rotate as a whole.
[0022] In one possible implementation, the outer periphery of the pen refill assembly is recessed with an adhesive groove containing adhesive material. The adhesive material can be circumferentially coated between the pen refill assembly and the pen barrel when they rotate relative to each other, forming an adhesive portion that bonded between the pen barrel and the pen refill assembly.
[0023] In this embodiment, the adhesive material is contained in an adhesive tank and applied between the pen refill assembly and the pen barrel by rotation, which facilitates reliable bonding between the pen refill assembly and the pen barrel.
[0024] In one possible implementation, the outer periphery of the pen refill assembly is recessed with an adhesive groove, and a gap exists between the outer peripheral surface of the pen refill assembly and the inner peripheral surface of the pen barrel. The stylus also includes an adhesive portion that fills the adhesive groove and the gap to bond the pen refill assembly and the pen barrel together.
[0025] In this embodiment, the adhesive portion fills the adhesive groove and gap, which ensures reliable bonding of the pen refill assembly and the pen barrel.
[0026] In one possible implementation, the pen holder is made of plastic material.
[0027] In this embodiment, the pen holder has lower cost and lighter weight.
[0028] Secondly, embodiments of this application provide a stylus, including a pen holder and a pen refill assembly. The inner circumferential surface of the pen holder defines an internal space extending in a first direction; the pen holder has a limiting boss protruding from the inner circumferential surface, the limiting boss extending circumferentially, and a notch defined between the two ends of the limiting boss in the circumferential direction. The pen refill assembly is mounted in the internal space and has a top abutment extending circumferentially, with a clearance space defined between the two ends of the top abutment in the circumferential direction; the projection of the top abutment in the first direction is located within the notch to be circumferentially offset from the limiting boss, and the projection of the limiting boss in the first direction is located within the clearance space to be offset from the top abutment.
[0029] In the embodiments of this application, the stylus is assembled by first inserting the pen refill assembly into the internal space until the limiting boss abuts against the top along the first direction, thus positioning the pen refill assembly and the pen barrel along the first direction (i.e., axial direction) and ensuring that the pen refill assembly and the pen barrel maintain their axial relative positions. Then, the pen refill assembly and the pen barrel are rotated relative to each other by a certain angle, so that the limiting boss is misaligned with the top and corresponds to the clearance space of the pen refill assembly. The stylus obtained in this way has accurate axial positioning between the pen refill assembly and the pen barrel, and the pen barrel can extend more freely into the clearance space along the first direction when its length changes due to thermal expansion and contraction, thereby reducing the possibility of cracks and breakage of the pen barrel.
[0030] Thirdly, embodiments of this application provide a stylus assembly method for assembling the aforementioned stylus, the stylus assembly method comprising:
[0031] Apply adhesive material to the outer periphery of the pen refill assembly;
[0032] The pen refill assembly is inserted into the internal space along the first direction until the limiting boss of the pen refill assembly abuts against the top of the pen holder along the first direction.
[0033] Rotate the pen refill assembly and pen holder relative to each other by a set angle until the limiting boss and the top abutment are offset circumferentially, and apply adhesive material circumferentially between the pen refill assembly and pen holder to bond and fix the pen refill assembly and pen holder.
[0034] The stylus assembly method in the embodiments of this application is simple to operate, and the stylus assembled by this stylus assembly method has accurate axial positioning between the pen core assembly and the pen barrel, and the pen barrel can extend more freely into the clearance space along the first direction when the length changes due to thermal expansion and contraction, thereby reducing the possibility of cracks and breakage of the pen barrel.
[0035] In one possible implementation, after the pen refill assembly and the pen barrel rotate relative to each other, adhesive material covers the pen refill assembly and the pen barrel around their perimeter.
[0036] This implementation method ensures reliable and circumferentially uniform bonding between the pen refill assembly and the pen holder.
[0037] Thirdly, embodiments of this application provide a stylus assembly method for assembling the aforementioned stylus, the stylus assembly method comprising:
[0038] The pen refill assembly is inserted into the internal space along the first direction until the limiting boss of the pen refill assembly abuts against the top of the pen holder along the first direction.
[0039] Rotate the pen refill assembly and pen holder relative to each other by a set angle until the limiting boss and the top abutment are circumferentially offset. Securely connect the pen refill assembly to the pen holder.
[0040] The stylus assembly method in the embodiments of this application is simple to operate, and the stylus assembled by this stylus assembly method has accurate axial positioning between the pen core assembly and the pen barrel, and the pen barrel can extend more freely into the clearance space along the first direction when the length changes due to thermal expansion and contraction, thereby reducing the possibility of cracks and breakage of the pen barrel.
[0041] Fourthly, embodiments of this application provide a stylus assembly apparatus for assembling the aforementioned stylus. The stylus assembly apparatus includes:
[0042] The first clamping component is used to clamp the pen holder;
[0043] The manipulation component includes a drive component and a second clamping component. The second clamping component is used to clamp the pen refill component. The drive component is connected to the second clamping component and is used to drive the pen refill component to be inserted into the internal space of the pen barrel along a first direction until the limiting boss abuts against the top in the first direction. The drive component also drives the pen refill component to rotate relative to the pen barrel until the limiting boss and the top are circumferentially offset.
[0044] The stylus assembly device in the embodiments of this application can conveniently and quickly assemble the aforementioned stylus.
[0045] In one possible implementation, the drive assembly includes a linear drive and a rotary drive. The linear drive is driven through the second clamping assembly, and the rotary drive is driven through the linear drive; or, the rotary drive is driven through the second clamping assembly, and the linear drive is driven through the rotary drive.
[0046] The stylus assembly device of this embodiment has a simple structure and can easily realize the insertion of the pen refill assembly along the first direction and the rotation of the pen refill assembly.
[0047] Fifthly, embodiments of this application provide an electronic device component, which includes an electronic device and the aforementioned stylus, the stylus being detachably coupled to the electronic device.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0113] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0114] Example
[0115] Figure 1 An electronic device assembly 500 is shown, which includes an electronic device 300 and a stylus 100.
[0116] Among them, electronic device 300 can be a tablet computer, mobile phone, wearable device, vehicle screen, industrial control screen, smart screen, or other device with touch screen 310.
[0117] The stylus 100 is detachably coupled to the electronic device 300. For example, see... Figure 1 When not in use, the stylus 100 can be attached to one side of the electronic device 300 via magnetic attraction or snap-fit. See also Figure 2 When needed, the stylus 100 can be removed from the electronic device 300, and writing, drawing or other operations can be performed on the electronic device 300.
[0118] The stylus 100 is coupled to the touch screen 310, that is, the stylus 100 can be sensed by the touch screen 310 and / or send signals to the touch screen 310.
[0119] There are several ways to couple the touchscreen 310 with the stylus 100.
[0120] For example, the stylus 100 can be an inductive pen. The touchscreen 310 of the electronic device 300 integrates an electromagnetic induction board. Coils are distributed on the electromagnetic induction board, and the inductive pen also integrates a coil. Based on the principle of electromagnetic induction, within the magnetic field range generated by the electromagnetic induction board, the inductive pen can accumulate electrical energy as it moves. The inductive pen can transmit the accumulated electrical energy to the electromagnetic induction board through free oscillation via the coil in the inductive pen. The electromagnetic induction board can scan the coil on the electromagnetic induction board based on the electrical energy from the inductive pen, calculate the position of the inductive pen on the touchscreen 310, thereby achieving coupling between the stylus 100 and the touchscreen 310.
[0121] The stylus 100 can be a capacitive stylus. The capacitive stylus can be a passive capacitive stylus or an active capacitive stylus. A passive capacitive stylus can be called a passive capacitive stylus, and an active capacitive stylus can be called an active capacitive stylus. When the stylus 100 is an active capacitive stylus, one or more electrodes can be disposed within it (e.g., inside the stylus tip). The active capacitive stylus can transmit signals through the electrodes. When the stylus 100 is an active capacitive stylus, an electrode array needs to be integrated on the touchscreen 310 that interacts with the stylus 100. In one embodiment, the electrode array can be a capacitive electrode array. The electronic device 300 can receive signals from the active capacitive stylus through the electrode array, and upon receiving the signal, identifies the position of the active capacitive stylus on the touchscreen 310 and its tilt angle based on changes in capacitance on the touchscreen 310, thereby achieving coupling between the touchscreen 310 and the stylus 100.
[0122] Based on the coupling between the stylus 100 and the touch screen 310, the stylus 100 can interact with the electronic device 300 in various ways. The electronic device 300 can predefine a variety of different input methods, such as tapping, drawing lines, and calling up menus, based on the obtained signals such as the position, tilt angle, and pressure of the stylus 100.
[0123] For example, when drawing on the touchscreen 310 using the stylus 100, the pressure applied corresponds to the thickness of the drawn lines. Similarly, when using the stylus 100 to replace mouse clicks, the pressure, duration, or tilt angle of the click defines the input method as a left-click, right-click, or double-click.
[0124] In addition to the exemplary method described above, the interaction between the stylus 100 and the electronic device 300 can also be any other suitable interaction method.
[0125] Figures 3-5 The stylus 100 of this embodiment is shown, which can be used as an input device for an electronic device 300 (such as a tablet computer).
[0126] Some known stylus 900 (see Figure 18During use, a ring-shaped crack (f1) easily appears on the section of the pen holder 901 near the pen tip 902, causing the stylus 900 to become unusable. Investigation and analysis revealed that this problem is widespread in known stylus 900 products, and occurs particularly frequently during low-temperature periods (such as winter). Disassembly and analysis of the stylus 900 exhibiting the crack (f1) revealed that the pen holder 901 is made of polycarbonate (PC) or other plastic materials, and the pen holder 901 and the pen tip are axially positioned by axial contact. Because the pen holder 901 is relatively long (approximately 150mm), its shrinkage is significant in low-temperature environments (approximately 0.3mm). This shrinkage is hindered by the axial contact between the pen holder 901 and the pen tip, resulting in shrinkage stress at the contact point and the appearance of the crack (f1).
[0127] In view of this, this embodiment provides a stylus 100 that can avoid or mitigate the above-mentioned problems. The following will describe it in detail with reference to the accompanying drawings.
[0128] See Figures 3-5 The stylus 100 of this embodiment includes a pen holder 10, a pen refill assembly 20, a pen tip 30, and a pen cap 40. The inner peripheral surface P1 of the pen holder 10 defines an internal space Q1 extending along a first direction Y. The pen refill assembly 20 is fitted into the internal space Q1, and the pen tip 30 and pen cap 40 are respectively connected to both ends of the pen holder 10. The first direction Y is the axial direction of the stylus 100.
[0129] In this embodiment, the pen holder 10 can be made of plastic materials such as polycarbonate (PC), and the pen refill assembly 20 can be partially made of metal materials.
[0130] In this embodiment, the internal space Q1 of the pen holder 10 is provided with an insertion port K1 at one end along the first direction Y. The insertion port K1 is used to allow the pen refill assembly 20 to be inserted into the internal space Q1. That is, when the stylus 100 is assembled, the pen refill assembly 20 can be inserted into the internal space Q1 from the insertion port K1.
[0131] See also Figure 6 and Figure 7 The pen holder 10 has a limiting boss 11 protruding from its inner circumferential surface P1, and the pen refill assembly 20 has a top abutment 21, which is circumferentially offset from the limiting boss 11. The limiting boss 11 has a stepped surface P2 facing the top abutment 21 along a first direction Y, and the top abutment 21 has a top surface P3 facing the limiting boss 11 along the first direction Y. The top surface P3 and the stepped surface P2 are located in the same plane perpendicular to the first direction Y. This ensures that the axial relative position of the pen refill assembly 20 and the pen holder 10 of the assembled stylus 100 remains consistent with the positioning state of the pen refill assembly 20 before rotation relative to the pen holder 10.
[0132] In this embodiment, during assembly, the pen tip assembly 20 can be inserted into the internal space Q1 until the limiting boss 11 abuts against the top 21 along the first direction Y. This achieves positioning of the pen tip assembly 20 and the pen holder 10 along the first direction Y (i.e., axial direction), ensuring that the pen tip assembly 20 and the pen holder 10 maintain an axial relative position. The relative position of the top 21 and the limiting boss 11 at this time can be found in [reference needed]. Figure 8 .
[0133] Subsequently, the pen refill assembly 20 and the pen holder 10 are rotated relative to each other by a certain angle (e.g., 180°), causing the top abutment 21 and the limiting boss 11 to be circumferentially offset. At this time, the relative positions of the top abutment 21 and the limiting boss 11 are visible. Figure 7 .exist Figure 7 In the staggered state shown, the pen refill assembly 20 and the pen barrel 10 are fixed to each other (e.g., by adhesive). The stylus 100 assembled in this way has several advantages. First, the axial relative position between the pen refill assembly 20 and the pen barrel 10 is determined by the positioning boss 11 and the abutment 21, ensuring accurate relative positioning. Second, when the pen barrel 10 changes length due to thermal expansion and contraction, it can freely extend and retract along the first direction Y, avoiding the limitation of the abutment 21 on the positioning boss 11. This reduces the possibility of pen barrel 10 breakage and improves the service life of the stylus 100.
[0134] Figure 6 In this embodiment, the limiting protrusion 11 is located at the end of the pen holder 10 along the first direction Y away from the insertion port K1 (i.e., near the pen tip 30). In other embodiments, the limiting protrusion 11 may also be located at the end of the pen holder 10 along the first direction Y near the insertion port K1, or the limiting protrusion 11 may be located at the middle position of the pen holder 10 along the first direction Y. That is, the position of the limiting protrusion 11 in the pen holder 10 along the first direction Y can be configured and is not limited here.
[0135] See Figure 7 and Figure 8The limiting boss 11 is an arc-shaped ring extending circumferentially, and the circumferential extension angle of the limiting boss 11 is less than or equal to 180°, such as 160°, 120°, 90°, etc. A notch C2 is defined between the two circumferential ends of the limiting boss 11. The top abutment 21 is an arc-shaped ring extending circumferentially, and the circumferential extension angle of the top abutment 21 is less than or equal to 180°, such as 160°, 120°, 90°, etc. A clearance space C3 is defined between the two circumferential ends of the top abutment 21. The projection of the top abutment 21 along the first direction Y is located within the notch C2, and the projection of the limiting boss 11 along the first direction Y is located within the clearance space C3. Thus, in a low-temperature environment, when the pen holder 10 contracts along the first direction Y, the limiting boss 11 of the pen holder 10 can enter the clearance space C3 along the first direction Y, while the top 21 of the pen refill assembly 20 can be accommodated in the notch C2, preventing the pen holder 10 from being stretched and cracked due to being limited by the pen refill assembly 20.
[0136] See Figure 9 In this embodiment, the end face of the pen holder 10 near the insertion port K1 is provided with a first positioning mark 12 and a second positioning mark 13 spaced apart in the circumferential direction, and the end of the pen refill assembly 20 near the insertion port K1 is provided with a third positioning mark 22.
[0137] With the third positioning mark 22 and the first positioning mark 12 radially aligned, the top abutment 21 and the limiting boss 11 correspond along the first direction Y (see [reference]). Figure 8 Furthermore, with the third positioning mark 22 and the second positioning mark 13 radially corresponding, the top abutment 21 and the limiting boss 11 are circumferentially offset (see...). Figure 7 ).
[0138] Optionally, the first positioning mark 12 and the second positioning mark 13 have different shapes to facilitate differentiation and identification. For example, Figure 9 In this design, the first positioning mark 12 can be a groove formed on the end face of the pen holder 10 near the insertion port K1, and the second positioning mark 13 can be a groove formed on the inner circumferential surface of the pen holder 10 near the insertion port K1. The third positioning mark 22 can be a protrusion formed from the outer periphery of the pen refill assembly 20.
[0139] Of course, in other embodiments, the first positioning mark 12, the second positioning mark 13, and the third positioning mark 22 may also take other forms, which are not limited here.
[0140] See Figure 10 and Figure 11 In this embodiment, the pen holder 10 and the pen refill assembly 20 are bonded and fixed together by the adhesive part 50.
[0141] To facilitate the application of adhesive between the pen holder 10 and the pen refill assembly 20, in this embodiment, the outer periphery of the pen refill assembly 20 is recessed with an adhesive-receiving groove C1 (also seen in...). Figure 5 The adhesive reservoir C1 contains adhesive material 51, which is applied circumferentially between the pen refill assembly 20 and the pen barrel 10 when they rotate relative to each other, forming an adhesive portion 50 that bonds the pen barrel 10 and the pen refill assembly 20 together. The formed adhesive portion 50 fills the adhesive reservoir C1 and the gap f2 between the pen barrel 10 and the pen refill assembly 20, ensuring that the pen refill assembly 20 and the pen barrel 10 are reliably bonded and fixed together.
[0142] In this embodiment, the adhesive material 51 can be a liquid adhesive. During assembly, adhesive is first applied to the adhesive reservoir C1 of the pen refill assembly 20. Due to the surface tension of the liquid adhesive, the amount of adhesive material 51 contained in the adhesive reservoir C1 will be greater than the volume of the adhesive reservoir C1 (see...). Figure 12 Then, the pen refill assembly 20, along with the adhesive material 51 on it, is inserted into the pen holder 10, and the pen refill assembly 20 and the pen holder 10 are rotated relative to each other until the limiting boss 11 and the top abutment 21 are circumferentially offset. During this rotation, the adhesive material 51 will fill the gap f2 between the pen holder 10 and the pen refill assembly 20 circumferentially, so that the pen refill assembly 20 and the pen holder 10 can be bonded by the adhesive material 51 at all points along the circumference, ensuring the reliability and circumferential uniformity of the bonding.
[0143] See Figure 13 In another embodiment, there are two adhesive reservoirs C1, which are distributed circumferentially. This allows the adhesive material 51 in the adhesive reservoirs C1 to coat the entire circumference of the pen barrel 10 and the pen refill assembly 20 when the rotation angle of the pen refill assembly 20 relative to the pen barrel 10 is small, thus ensuring the reliability and circumferential uniformity of the bonding.
[0144] See Figure 14 and Figure 15 In another embodiment, there are multiple limiting bosses 11, which are spaced apart circumferentially. There are also multiple abutment tops 21, which are spaced apart circumferentially. Furthermore, during assembly, the multiple abutment tops 21 and the multiple limiting bosses 11 can abut against each other in a one-to-one correspondence along the first direction Y (see...). Figure 15 After that, rotate circumferentially relative to each other until they are relatively offset (see...). Figure 14 Then the pen refill assembly 20 and the pen holder 10 can be fixed to each other.
[0145] For example, Figure 14 and Figure 15 In the middle, there are two limiting protrusions 11, which are symmetrically distributed; correspondingly, there are also two abutment tops 21, which are symmetrically distributed. Thus, when the stylus 100 is assembled... Figure 14When the pen refill assembly 20 is positioned as shown, it can be positioned by two abutment tops 21 and two limiting protrusions 11, which ensures reliable positioning and balanced force distribution.
[0146] See you again Figure 5 In this embodiment, the pen refill assembly 20 includes a front refill section 20a, a middle refill section 20b, and a rear refill section 20c connected sequentially along the first direction Y. A top abutment 21 is disposed on the front refill section 20a. A clamping portion 23 is provided at the end of the rear refill section 20c away from the front refill section 20a, for clamping and rotating the entire pen refill assembly 20. The rear refill section 20c includes a battery casing 24 and a battery 25. The battery 25 is housed in the battery casing 24. The clamping portion 23 is located at the end of the battery casing 24 away from the front refill section 20a to facilitate clamping and rotation.
[0147] The adhesive reservoir C1 can be located in the middle section 20b of the pen refill. Optionally, the middle section 20b of the pen refill includes a first support 26 and a second support 27, which are joined together circumferentially to form a generally cylindrical structure. The adhesive reservoir C1 is located on the outer circumferential surface of the first support 26.
[0148] See Figure 16 This embodiment also provides a stylus assembly device 700 for assembling... Figures 3-15 The stylus 100 is shown. The stylus assembly device 700 includes a first clamping component 710 and an operating component 720.
[0149] The first clamping component 710 is used to clamp the pen holder 10. The first clamping component 710 can be a common clamp.
[0150] The manipulation component 720 includes a drive component 721 and a second clamping component 722. The second clamping component 722 is used to clamp the pen refill assembly 20, such as the clamping part 23 clamped on the pen refill assembly 20. The drive component 721 is drively connected to the second clamping component 722 and is used to drive the pen refill assembly 20 into the internal space Q1 of the pen holder 10 along the first direction Y until the limiting boss 11 abuts against the top 21 along the first direction Y, and drive the pen refill assembly 20 to rotate relative to the pen holder 10 to a position where the limiting boss 11 and the top 21 are circumferentially offset.
[0151] Optionally, the drive assembly 721 includes a linear drive 721a and a rotary drive 721b. The rotary drive 721b is driveably connected to the second clamping assembly 722, and the linear drive 721a is driveably connected to the rotary drive 721b. The linear drive 721a can be a linear cylinder, a linear motor, or other linear actuator, and the rotary drive 721b can be a rotary motor, etc.
[0152] See Figure 17This embodiment also provides another stylus assembly device 700a, in which the linear drive 721a is connected to the second clamping component 722 in the manipulation component 720, and the rotary drive 721b is connected to the linear drive 721a, that is, the positions of the linear drive 721a and the rotary drive 721b are swapped.
[0153] This embodiment also provides a method for assembling a stylus, used for assembling... Figures 3-15 The stylus 100 shown includes a stylus assembly method comprising:
[0154] Adhesive material 51 is applied to the outer periphery of the pen refill assembly 20, for example, liquid adhesive material 51 is applied to the adhesive groove C1 on the outer periphery of the pen refill assembly 20;
[0155] The pen refill assembly 20 is inserted into the internal space Q1 along the first direction Y until the limiting boss 11 of the pen refill assembly 20 abuts against the top 21 of the pen holder 10 along the first direction Y.
[0156] The pen refill assembly 20 and the pen holder 10 are rotated relative to each other by a set angle until the limiting boss 11 and the abutment 21 are circumferentially offset. Adhesive material 51 is then applied circumferentially between the pen refill assembly 20 and the pen holder 10, bonding and fixing them together. The adhesive material 51 can be cured by standing, heating, or other methods to secure the pen refill assembly 20 and the pen holder 10.
[0157] In this embodiment, after the pen refill assembly 20 and the pen holder 10 rotate relative to each other, the adhesive material 51 covers the pen refill assembly 20 and the pen holder 10 around the perimeter to ensure reliable and uniform adhesion.
[0158] In other embodiments, the adhesive material 51 may not be applied, and the pen refill assembly 20 and the pen holder 10 may be fixed to each other in other ways, such as by threaded connection, snap-fit connection, etc., which are not limited here.
[0159] In summary, the stylus 100 of this embodiment solves the problem of pen cylinder 10 cracking by rotating the pen core assembly 20 relative to the pen cylinder 10 so that the top 21 of the pen core assembly 20 is misaligned with the limiting protrusion 11 of the pen cylinder 10. The solution is simple, highly feasible, low cost, and has no impact on writing function and user experience.
