Description

Technical Field

[0001] The present application relates to the field of electronic terminals, and in particular, to a stylus, a stylus assembly device and method, and an electronic device component. Background Art

[0002] Some known stylus pens have cracks on the outer periphery of the pen barrel. Summary of the invention

[0003] The present application provides a stylus, a stylus assembly device and method, and an electronic device assembly to solve the problem of cracks appearing on the periphery of a pen barrel of a known stylus.

[0004] In a first aspect, an embodiment of the present application provides a stylus pen, which includes a pen barrel and a pen core assembly. The inner circumference of the pen barrel defines an internal space extending along a first direction; the pen barrel has a limiting boss protruding from the inner circumference. The pen core assembly is installed in the internal space and has a stop top; the stop top and the limiting boss are staggered along the circumferential direction.

[0005] In the stylus of the embodiment of the present application, when assembling, the refill assembly can be first loaded into the internal space until the limiting boss abuts against the abutting top in the first direction, so as to realize the positioning of the refill assembly and the pen barrel in the first direction (i.e., axial direction), and ensure that the refill assembly and the pen barrel maintain the axial relative position; then, the refill assembly and the pen barrel are relatively rotated at a certain angle, so that the abutting top and the limiting boss are staggered in the circumferential direction, and the refill assembly and the pen barrel are fixed to each other in the staggered state. The stylus obtained in this way has accurate axial positioning between the refill assembly and the pen barrel, and the pen barrel can be relatively freely extended and retracted in 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.

[0006] In a possible implementation, the limiting boss has a step surface along the first direction toward the abutting top portion. The abutting top portion has an abutting surface along the first direction toward the limiting boss. The abutting surface and the step surface are located in the same plane perpendicular to the first direction.

[0007] In this way, it can be ensured that the relative axial position of the core assembly and the pen barrel of the assembled stylus pen remains consistent with the positioning state of the core assembly before it rotates relative to the pen barrel.

[0008] In a possible implementation, the limiting boss is in an arc ring shape extending in the circumferential direction, 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 abutting top is in an arc ring shape extending in the circumferential direction, and the circumferential extension angle of the abutting top is less than or equal to 180°; an escape space is defined between the two circumferential ends of the abutting top. The projection of the abutting top along the first direction is located in the notch, and the projection of the limiting boss along the first direction is located in the escape space.

[0009] In this way, in a low temperature environment, when the pen barrel contracts along the first direction, the limiting boss of the pen barrel can enter the avoidance space along the first direction, and the top of the pen core assembly can be accommodated in the gap, thereby preventing the pen barrel from being limited by the pen core assembly and being pulled to form cracks.

[0010] In a possible implementation, the refill assembly is configured to extend in a first direction to a position where the abutting top abuts against the limiting boss, and then rotate relative to the pen barrel to a state where the abutting top and the limiting boss are circumferentially staggered.

[0011] In this embodiment, the refill assembly is installed in the first direction and then rotated, which facilitates assembly and prevents the pen barrel from cracking due to expansion and contraction.

[0012] In a possible embodiment, the number of the limiting bosses is one, and the number of the abutting tops is one; or, there are multiple limiting bosses, and the multiple limiting bosses are arranged at intervals along the circumferential direction; there are multiple abutting tops, and the multiple abutting tops are distributed at intervals along the circumferential direction; and, during assembly, the multiple abutting tops and the multiple limiting bosses can abut against each other one by one along the first direction, and then rotate relative to each other along the circumferential direction to be relatively staggered.

[0013] In this embodiment, there are one or more limiting bosses, each of which can achieve axial positioning of the pen barrel and the pen core assembly.

[0014] In a possible implementation, the internal space of the pen barrel is provided with an insertion port at one end along the first direction, and the insertion port is used to allow the pen core assembly to be inserted into the internal space. The limiting boss is provided at one end of the pen barrel along the first direction close to the insertion port, or the limiting boss is provided at one end of the pen barrel along the first direction away from the insertion port, or the limiting boss is provided at the middle position of the pen barrel along the first direction.

[0015] In this embodiment, the position of the limiting boss can be set as required.

[0016] In a possible implementation, the end surface of the pen barrel near the insertion port is provided with a first positioning mark and a second positioning mark spaced circumferentially; the end of the pen core assembly near the insertion port is provided with a third positioning mark. When the third positioning mark corresponds to the first positioning mark in the radial direction, the abutting top portion corresponds to the limiting boss in the first direction; and when the third positioning mark corresponds to the second positioning mark in the radial direction, the abutting top portion and the limiting boss are staggered in the circumferential direction.

[0017] In this way, the circumferential relative positions of the core assembly and the pen barrel can be easily identified, ensuring that during the assembly process, the core assembly and the pen barrel are accurately positioned along the axial direction and are completely offset from each other after relative rotation.

[0018] In a possible implementation, the refill assembly includes a refill front section, a refill middle section, and a refill rear section connected in sequence along a first direction. The abutment top is arranged at the refill front section, and a clamping portion is arranged at one end of the refill rear section away from the refill front section, which is used to be clamped to drive the refill assembly to rotate as a whole.

[0019] In this embodiment, the front section of the refill is arranged at the top, the refill assembly and the pen barrel are reliably positioned axially, and the clamping portion is convenient for being clamped and rotated.

[0020] In a possible implementation, the rear section of the refill includes a battery tube and a battery, the battery is accommodated in the battery tube, and the clamping portion is disposed at an end of the battery tube away from the front section of the refill.

[0021] In this embodiment, the clamping portion is arranged at one end of the battery tube away from the front section of the pen core, so as to be clamped to drive the pen core assembly to rotate as a whole.

[0022] In a possible embodiment, a glue-containing groove is recessed on the outer circumference of the refill assembly, and the glue-containing groove contains adhesive material. The adhesive material can be coated circumferentially between the refill assembly and the pen barrel when the refill assembly and the pen barrel rotate relative to each other, and form a glued portion bonded to the pen barrel and the refill assembly.

[0023] In this embodiment, the adhesive material is contained in the adhesive containing groove and is coated between the refill assembly and the pen barrel by rotation, so as to facilitate reliable gluing of the refill assembly and the pen barrel.

[0024] In a possible implementation, a glue groove is concavely formed on the outer circumference of the core assembly, and a gap is provided between the outer circumference of the core assembly and the inner circumference of the pen barrel. The stylus also includes a gluing part, which is filled in the glue groove and the gap to bond and connect the core assembly and the pen barrel.

[0025] In this embodiment, the gluing portion is filled in the gluing groove and the gap, which can ensure that the refill assembly and the pen barrel are reliably glued.

[0026] In a possible implementation manner, the pen barrel is made of plastic material.

[0027] In this embodiment, the pen holder has low cost and low weight.

[0028] In a second aspect, an embodiment of the present application provides a stylus, comprising a pen barrel and a refill assembly. The inner circumferential surface of the pen barrel defines an internal space extending in a first direction; the pen barrel has a limiting boss protruding from the inner circumferential surface, the limiting boss extends in a circumferential direction, and a gap is defined between the two ends of the limiting boss in the circumferential direction. The refill assembly is installed in the internal space and has a stopper, the stopper extends in a circumferential direction, and an escape space is defined between the two ends of the stopper in the circumferential direction; the projection of the stopper in the first direction is located in the escape space to be staggered with the limiting boss in the circumferential direction, and the projection of the limiting boss in the first direction is located in the escape space to be staggered with the stopper.

[0029] In the stylus of the embodiment of the present application, when assembling, the refill assembly can be first loaded into the internal space until the limiting boss abuts against the abutting top along the first direction, so as to realize the positioning of the refill assembly and the pen barrel along the first direction (i.e., axial direction), and ensure that the refill assembly and the pen barrel maintain the axial relative position; then, the refill assembly and the pen barrel are relatively rotated at a certain angle, so that the limiting boss is staggered with the abutting top and corresponds to the avoidance space of the refill assembly. The stylus thus obtained has accurate axial positioning between the refill assembly and the pen barrel, and the pen barrel can freely extend into the avoidance 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.

[0030] In a third aspect, an embodiment of the present application provides a stylus pen assembly method, which is used to assemble the aforementioned stylus pen. The stylus pen assembly method includes:

[0031] Applying adhesive material on the periphery of the refill assembly;

[0032] Installing the refill assembly into the internal space along a first direction until the limiting boss of the refill assembly abuts against the abutting top of the pen barrel along the first direction;

[0033] The core assembly and the pen barrel are relatively rotated at a set angle to make the limiting boss and the abutting top staggered along the circumferential direction, and the adhesive material is coated between the core assembly and the pen barrel along the circumferential direction to bond and fix the core assembly and the pen barrel.

[0034] The stylus pen assembly method in the embodiment of the present application is simple to operate, and the axial positioning between the core assembly and the pen barrel of the stylus pen assembled by the stylus pen assembly method is accurate, and the pen barrel can extend into the avoidance space relatively freely 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 a possible implementation manner, after the core assembly and the pen barrel rotate relative to each other, the adhesive material covers the core assembly and the pen barrel in a circle.

[0036] This implementation can ensure that the gluing of the core assembly and the pen barrel is reliable and circumferentially uniform.

[0037] In a third aspect, an embodiment of the present application provides a stylus pen assembly method, which is used to assemble the aforementioned stylus pen. The stylus pen assembly method includes:

[0038] Installing the refill assembly into the internal space along a first direction until the limiting boss of the refill assembly abuts against the abutting top of the pen barrel along the first direction;

[0039] The core assembly and the pen barrel are rotated relative to each other at a set angle, so that the limiting boss and the abutting top are staggered along the circumferential direction. The core assembly is fixedly connected to the pen barrel.

[0040] The stylus pen assembly method in the embodiment of the present application is simple to operate, and the axial positioning between the core assembly and the pen barrel of the stylus pen assembled by the stylus pen assembly method is accurate, and the pen barrel can extend into the avoidance space relatively freely 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] In a fourth aspect, an embodiment of the present application provides a stylus pen assembly device, which is used to assemble the aforementioned stylus pen, and the stylus pen assembly device includes:

[0042] A first clamping assembly, used for clamping the pen holder;

[0043] The operating component includes a driving component and a second clamping component, the second clamping component is used to clamp the refill component, the driving component is transmission-connected to the second clamping component, and is used to drive the refill component to be loaded into the internal space of the pen barrel along the first direction through the second clamping component to the position where the limiting boss abuts against the abutting top along the first direction, and drive the refill component to rotate relative to the pen barrel to the position where the limiting boss and the abutting top are staggered along the circumferential direction.

[0044] The stylus pen assembly device in the embodiment of the present application can assemble the aforementioned stylus pen conveniently and quickly.

[0045] In a possible embodiment, the driving assembly includes a linear driving member and a rotary driving member. The linear driving member is transmission-connected to the second clamping assembly, and the rotary driving member is transmission-connected to the linear driving member; or the rotary driving member is transmission-connected to the second clamping assembly, and the linear driving member is transmission-connected to the rotary driving member.

[0046] The stylus pen assembly device of this embodiment has a simple structure and can conveniently implement the insertion of the core assembly along the first direction and the rotation of the core assembly.

[0047] In a fifth aspect, an embodiment of the present application provides an electronic device assembly, which includes an electronic device and the aforementioned stylus pen, and the stylus pen can be detachably matched with the electronic device.

[0110] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0111] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be a centered element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may also be a centered element. When an element is considered to be "set on" another element, it may be directly set on the other element or there may also be a centered element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0112] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present application. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0113] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments 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 pen 100 .

[0116] Among them, the electronic device 300 can be a tablet computer, a mobile phone, a wearable device, a car screen, an industrial control screen, a smart screen, etc., which has a touch screen 310.

[0117] The stylus pen 100 can be detachably matched with the electronic device 300. For example, see Figure 1 When not in use, the stylus pen 100 can be fixed to one side of the electronic device 300 by means of magnetic attraction or snap connection. Figure 2 When needed, the stylus pen 100 can be removed from the electronic device 300 to perform writing, drawing or other operations on the electronic device 300.

[0118] The stylus pen 100 is coupled to the touch screen 310 , that is, the stylus pen 100 can be sensed by the touch screen 310 and / or send signals to the touch screen 310 .

[0119] There are many ways to achieve coupling between the touch screen 310 and the stylus pen 100 .

[0120] For example, the stylus 100 may be an inductive pen. The touch screen 310 of the electronic device 300 is integrated with an electromagnetic induction board. Coils are distributed on the electromagnetic induction board, and coils are also integrated in the inductive pen. Based on the principle of electromagnetic induction, within the magnetic field generated by the electromagnetic induction board, the inductive pen can accumulate electrical energy as the inductive pen moves. The inductive pen can transfer 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 touch screen 310, and thereby achieve coupling between the stylus 100 and the touch screen 310.

[0121] The stylus 100 may be a capacitive stylus. The capacitive stylus may be a passive capacitive stylus or an active capacitive stylus. A passive capacitive stylus may be referred to as a passive capacitive stylus, and an active capacitive stylus may be referred to as an active capacitive stylus. When the stylus 100 is an active capacitive stylus, one or more electrodes may be provided in the active capacitive stylus (e.g., in the pen tip). The active capacitive stylus may transmit signals through the electrodes. When the stylus 100 is an active capacitive stylus, an electrode array needs to be integrated on the touch screen 310 that interacts with the stylus 100. In one embodiment, the electrode array may be a capacitive electrode array. The electronic device 300 may receive a signal from the active capacitive stylus through the electrode array, and when the signal is received, the position of the active capacitive stylus on the touch screen 310 and the inclination angle of the active capacitive stylus may be identified based on the change in the capacitance value on the touch screen 310, thereby achieving coupling between the touch screen 310 and the stylus 100.

[0122] Based on the coupling of the stylus 100 and the touch screen 310, the stylus 100 can interact with the electronic device 300 in various forms. The electronic device 300 can predefine a variety of different input methods, such as clicking, drawing lines, calling up menus, etc., based on the obtained signals such as the position, tilt angle, pressure, etc. of the stylus 100.

[0123] For example, when the stylus 100 is used to draw on the touch screen 310, the pressure corresponds to the thickness of the drawn line, etc. For another example, when the stylus 100 is used to replace the mouse click operation, the click is defined as a left click, a right click, or a double click, etc., by the pressure, duration, or tilt angle of the click.

[0124] The interaction between the stylus pen 100 and the electronic device 300 may be any other suitable interaction manner besides the above exemplary manner.

[0125] Figure 3-Figure 5 The stylus pen 100 of this embodiment is shown, which can be used as an input device of an electronic device 300 (such as a tablet computer).

[0126] Some known stylus 900 (see Fig.18) During use, there is a problem that a section of the pen barrel 901 near the pen tip 902 is prone to an annular crack f1, causing the stylus 900 to be damaged and unable to be used normally. According to investigation and analysis, this problem is more common in known stylus 900 products, and occurs more frequently during periods of lower temperatures (such as winter). After disassembling and analyzing the stylus 900 with the crack f1, it was found that the pen barrel 901 is made of plastic materials such as polycarbonate (PC), and the pen barrel 901 and the pen core are axially positioned against each other by axially abutting against each other. In this way, since the pen barrel 901 is relatively long (such as a length of about 150 mm), the contraction of the pen barrel 901 is relatively large (such as reaching 0.3 mm) in a low temperature environment, and the contraction is hindered by the axial abutment between the pen barrel 901 and the pen core, resulting in the contraction stress of the pen barrel 901 at the abutment with the pen core, resulting in the crack f1.

[0127] In view of this, the present embodiment provides a stylus pen 100, which can avoid or alleviate the above problems. The following will be described in detail with reference to the accompanying drawings.

[0128] See also Figure 3-Figure 5 The stylus pen 100 of this embodiment includes a pen barrel 10, a pen core assembly 20, a pen tip 30 and a pen cap 40. The inner circumference P1 of the pen barrel 10 defines an internal space Q1 extending along a first direction Y, the pen core assembly 20 is fitted in the internal space Q1, and the pen tip 30 and the pen cap 40 are respectively connected to both ends of the pen barrel 10. The first direction Y is the axial direction of the stylus pen 100.

[0129] In this embodiment, the pen holder 10 can be made of plastic materials such as polycarbonate (PC), and the 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, and the insertion port K1 is used to allow the core assembly 20 to be inserted into the internal space Q1. That is, when the stylus pen 100 is assembled, the core 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 barrel 10 has a limiting boss 11 protruding from the inner circumferential surface P1, and the pen core assembly 20 has an abutting top portion 21, which is staggered from the limiting boss 11 along the circumferential direction. The limiting boss 11 has a step surface P2 facing the abutting top portion 21 along the first direction Y, and the abutting top portion 21 has an abutting top surface P3 facing the limiting boss 11 along the first direction Y. The abutting top surface P3 and the step surface P2 are located in the same plane perpendicular to the first direction Y. In this way, it can be ensured that the relative position of the pen core assembly 20 and the pen barrel 10 in the axial direction of the assembled stylus 100 remains consistent with the positioning state of the pen core assembly 20 before it rotates relative to the pen barrel 10.

[0132] When assembling the stylus pen 100 in this embodiment, the refill assembly 20 can be first installed into the internal space Q1 until the limiting boss 11 abuts against the abutting top portion 21 along the first direction Y, so that the refill assembly 20 and the pen barrel 10 are positioned along the first direction Y (i.e., axial direction), ensuring that the refill assembly 20 and the pen barrel 10 maintain an axial relative position. At this time, the relative position of the abutting top portion 21 and the limiting boss 11 can be seen in FIG. Figure 8 .

[0133] Then, the refill assembly 20 and the pen barrel 10 are relatively rotated by a certain angle (such as 180°) so that the abutting top portion 21 and the limiting boss 11 are staggered along the circumferential direction. At this time, the relative positions of the abutting top portion 21 and the limiting boss 11 can be seen at Figure 7 .exist Figure 7 In the staggered state shown, the core assembly 20 and the pen barrel 10 are fixed to each other (such as glued and fixed). The handwriting pen 100 assembled in this way, on the one hand, the axial relative position between the core assembly 20 and the pen barrel 10 has been determined by the positioning boss 11 and the abutment portion 21, the relative position is accurate, and the pen barrel 10 can be relatively freely extended and retracted along the first direction Y when the length changes due to thermal expansion and contraction, avoiding the limitation of the limiting boss 11 by the abutment portion 21, thereby reducing the possibility of the pen barrel 10 breaking and increasing the service life of the handwriting pen 100.

[0134] Figure 6 In the embodiment, the limiting boss 11 is disposed at the end of the pen barrel 10 away from the insertion port K1 along the first direction Y (i.e., the end close to the pen tip 30). In other embodiments, the limiting boss 11 may also be disposed at the end of the pen barrel 10 close to the insertion port K1 along the first direction Y, or the limiting boss 11 may be disposed at the middle position of the pen barrel 10 along the first direction Y. That is, the setting position of the limiting boss 11 on the pen barrel 10 along the first direction Y may be determined according to the setting, and is not limited here.

[0135] See also Figure 7 and Figure 8The limiting boss 11 is in an arc ring shape extending in the circumferential direction, 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 circumferential ends of the limiting boss 11. The abutting top portion 21 is in an arc ring shape extending in the circumferential direction, and the circumferential extension angle of the abutting top portion 21 is less than or equal to 180°, such as 160°, 120°, 90°, etc., and an escape space C3 is defined between the circumferential ends of the abutting top portion 21. The projection of the abutting top portion 21 along the first direction Y is located in the notch C2, and the projection of the limiting boss 11 along the first direction Y is located in the escape space C3. In this way, in a low temperature environment, when the pen barrel 10 contracts along the first direction Y, the limiting boss 11 of the pen barrel 10 can enter the avoidance space C3 along the first direction Y, and the top 21 of the core assembly 20 can be accommodated in the notch C2, thereby preventing the pen barrel 10 from being limited by the core assembly 20 and being pulled to form cracks.

[0136] See also Fig. 9 In this embodiment, the end surface of the pen barrel 10 close to the insertion port K1 is provided with a first positioning mark 12 and a second positioning mark 13 spaced apart along the circumferential direction, and the end of the refill assembly 20 close to the insertion port K1 is provided with a third positioning mark 22.

[0137] When the third positioning mark 22 corresponds to the first positioning mark 12 in the radial direction, the abutting portion 21 corresponds to the limiting boss 11 in the first direction Y (see FIG. Figure 8 ); and, in the state where the third positioning mark 22 corresponds to the second positioning mark 13 in the radial direction, the abutment top 21 and the limiting boss 11 are staggered in the circumferential direction (see Figure 7 ).

[0138] Optionally, the first positioning mark 12 and the second positioning mark 13 have different shapes to facilitate identification. Fig. 9 In the embodiment, the first positioning mark 12 may be a groove formed on the end surface of the pen barrel 10 near the insertion port K1, and the second positioning mark 13 may be a groove formed on the inner circumference of the pen barrel 10 near the insertion port K1. The third positioning mark 22 may be a protruding block formed from the outer circumference of the pen core 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 be in other forms, which are not limited here.

[0140] See also Fig.10 and Fig.11 In this embodiment, the pen barrel 10 and the pen core assembly 20 are bonded and fixed by a bonding portion 50 .

[0141] In order to realize the application of glue between the pen barrel 10 and the pen core assembly 20, in this embodiment, the outer periphery of the pen core assembly 20 is concavely provided with a glue containing groove C1 (also shown in Figure 5 ), the adhesive groove C1 contains an adhesive material 51, and the adhesive material 51 can be coated between the pen core assembly 20 and the pen barrel 10 along the circumferential direction when the pen core assembly 20 and the pen barrel 10 rotate relative to each other, and form an adhesive portion 50 that is bonded and connected between the pen barrel 10 and the pen core assembly 20. Among them, the formed adhesive portion 50 is filled in the adhesive groove C1 and the gap f2 between the pen barrel 10 and the pen core assembly 20 to ensure that the pen core assembly 20 and the pen barrel 10 are reliably bonded and fixed together.

[0142] The adhesive material 51 in this embodiment can be liquid glue. During assembly, glue is first applied to the glue groove C1 of the refill assembly 20. Due to the surface tension of the liquid glue, the amount of adhesive material 51 contained in the glue groove C1 is greater than the volume of the glue groove C1 (see Fig.12 ); then the core assembly 20 together with the adhesive material 51 thereon is loaded into the pen barrel 10, and the core assembly 20 and the pen barrel 10 are relatively rotated to a position where the limiting boss 11 and the abutting top 21 are circumferentially staggered. During the rotation process, the adhesive material 51 will be filled into the gap f2 between the pen barrel 10 and the core assembly 20 along the circumferential direction, so that the core assembly 20 and the pen barrel 10 can be bonded by the adhesive material 51 at all places along the circumferential direction, ensuring the reliability of the bonding and the circumferential uniformity.

[0143] See also Fig.13 In another embodiment, there are two glue grooves C1, and the two glue grooves C1 are spaced apart along the circumference. In this way, when the rotation angle of the refill assembly 20 relative to the pen barrel 10 is small, the adhesive material 51 in the glue groove C1 can also be rotated to coat the entire circumference of the pen barrel 10 and the refill assembly 20, thereby ensuring the reliability and circumferential uniformity of the bonding.

[0144] See also Fig.14 and Fig.15 In another embodiment, there are multiple limiting bosses 11, and the multiple limiting bosses 11 are arranged at intervals along the circumferential direction. There are multiple abutting tops 21, and the multiple abutting tops 21 are distributed at intervals along the circumferential direction. In addition, during assembly, the multiple abutting tops 21 and the multiple limiting bosses 11 can abut against each other one by one along the first direction Y (see Fig.15 ) and then rotate relative to each other in the circumferential direction until they are relatively staggered (see Fig.14 ), then the core assembly 20 and the pen barrel 10 can be fixed to each other.

[0145] For example, Fig.14 and Fig.15 In the embodiment, there are two limiting bosses 11, which are symmetrically distributed; correspondingly, there are two abutting tops 21, which are symmetrically distributed. Fig.14In the positioning state shown, the refill assembly 20 can be positioned by the two abutting tops 21 and the two limiting bosses 11, and the positioning is reliable and the force is balanced.

[0146] See again Figure 5 In this embodiment, the refill assembly 20 includes a refill front section 20a, a refill middle section 20b and a refill rear section 20c which are sequentially connected along the first direction Y. The abutment portion 21 is provided at the refill front section 20a, and a clamping portion 23 is provided at one end of the refill rear section 20c away from the refill front section 20a, which is used to be clamped to drive the refill assembly 20 to rotate as a whole. The refill rear section 20c includes a battery barrel 24 and a battery 25, and the battery 25 is accommodated in the battery barrel 24. The clamping portion 23 is provided at one end of the battery barrel 24 away from the refill front section 20a to facilitate the clamping and rotation.

[0147] The glue containing groove C1 can be arranged in the middle section 20b of the pen core. Optionally, the middle section 20b of the pen core includes a first bracket 26 and a second bracket 27, which are assembled into a substantially cylindrical structure along the circumferential direction. The glue containing groove C1 is arranged on the outer circumferential surface of the first bracket 26.

[0148] See also Fig.16 This embodiment also provides a stylus assembly device 700 for assembling Figure 3-Figure 15 The stylus pen 100 is shown. The stylus pen assembly device 700 includes a first clamping component 710 and a manipulation component 720 .

[0149] The first clamping assembly 710 is used to clamp the pen holder 10. The first clamping assembly 710 may be a common clamp.

[0150] The operating assembly 720 includes a driving assembly 721 and a second clamping assembly 722, wherein the second clamping assembly 722 is used to clamp the refill assembly 20, such as clamping the clamping portion 23 on the refill assembly 20. The driving assembly 721 is connected to the second clamping assembly 722 in a transmission manner, and is used to drive the refill assembly 20 to be loaded into the inner space Q1 of the pen barrel 10 along the first direction Y through the second clamping assembly 722 to the position where the limiting boss 11 abuts against the abutting portion 21 along the first direction Y, and drive the refill assembly 20 to rotate relative to the pen barrel 10 to the position where the limiting boss 11 and the abutting portion 21 are staggered along the circumferential direction.

[0151] Optionally, the driving assembly 721 includes a linear driving member 721a and a rotating driving member 721b. The rotating driving member 721b is connected to the second clamping assembly 722 by transmission, and the linear driving member 721a is connected to the rotating driving member 721b by transmission. The linear driving member 721a can be a linear cylinder, a linear motor or other linear drive, and the rotating driving member 721b can be a rotating motor, etc.

[0152] See also Fig.17This embodiment also provides another stylus assembly device 700a, in which in the operating component 720, the linear driving member 721a is transmission-connected to the second clamping component 722, and the rotating driving member 721b is transmission-connected to the linear driving member 721a, that is, the positions of the linear driving member 721a and the rotating driving member 721b are swapped.

[0153] This embodiment also provides a stylus assembly method for assembling Figure 3-Figure 15 The stylus pen 100 shown, the stylus pen assembly method includes:

[0154] Applying the adhesive material 51 on the periphery of the refill assembly 20, for example, applying the liquid adhesive material 51 to the adhesive groove C1 on the periphery of the refill assembly 20;

[0155] The refill assembly 20 is installed into the internal space Q1 along the first direction Y until the limiting boss 11 of the refill assembly 20 abuts against the abutting portion 21 of the pen barrel 10 along the first direction Y;

[0156] The refill assembly 20 and the pen barrel 10 are relatively rotated at a set angle to a position where the limiting boss 11 and the abutting top portion 21 are staggered along the circumferential direction, and the adhesive material 51 is applied between the refill assembly 20 and the pen barrel 10 along the circumferential direction to bond and fix the refill assembly 20 and the pen barrel 10. The adhesive material 51 can be cured by standing, heating or other methods to bond the refill assembly 20 and the pen barrel 10.

[0157] In this embodiment, after the core assembly 20 and the pen barrel 10 rotate relative to each other, the adhesive material 51 covers the core assembly 20 and the pen barrel 10 in one circle to ensure reliable and uniform bonding.

[0158] In other embodiments, the adhesive material 51 may not be applied, and the refill assembly 20 and the pen barrel 10 may be fixed to each other in other ways, such as threaded connection, snap connection, etc., which is not limited here.

[0159] In summary, the stylus pen 100 of the present embodiment can solve the problem of cracking of the pen barrel 10 by rotating the core assembly 20 relative to the pen barrel 10 so that the abutting top 21 of the core assembly 20 is offset from the limiting boss 11 of the pen barrel 10. The solution is simple, highly feasible, low-cost, and has no impact on the writing function and the user experience.
