[0043] The invention provides a capacitive stylus.

[0044] Reference Figure 1 to Figure 14 In an embodiment of the present invention, a capacitive stylus includes:

[0045] The pen barrel 10 has a charging interface portion 11 and a logo portion 12 on its outer side wall;

[0046] The pen cap 20 has a receiving cavity with one end open, and the outer wall of the pen cap 20 has a display hole 21.

[0047] The pen tube 10 extends from the opening into the accommodating cavity, and the pen cap 20 can be rotated and switched between a first position and a second position relative to the pen tube 10 so that the display hole 21 is aligned with the charging interface portion 11 or the identification portion 12;

[0048] A first magnetic component 30, disposed on the pen cap 20;

[0049] The second magnetic component 40 is arranged on the pen tube 10. The second magnetic component 40 is arranged opposite to the first magnetic component 30. A magnetic repulsion force is generated between the first magnetic component 30 and the second magnetic component 40. The magnetic repulsion force is used to push the pen cap 20 to continue to rotate to the first position or the second position after the pen cap 20 rotates a preset angle relative to the pen tube 10.

[0050] The scheme of the present invention describes a design of a capacitive pen with a magnetic function. It realizes the fixed position rotation of the pen cap 20 through the interaction between the pen cap 20 and the pen tube 10 and two magnetic components, so that the user can easily access different parts on the pen tube (such as the charging interface part and the identification part). When the user picks up the capacitive pen, the pen cap 20 is in the default first position, and the display hole 21 may be aligned with the identification part 12 on the pen tube. The user can rotate the pen cap 20 as needed. Due to the magnetic repulsion generated by the magnetic component between the pen cap 20 and the pen tube 10, the pen cap 20 will automatically locate to a preset position, that is, the first position or the second position after rotating to a specific angle. If the user needs to charge the capacitive pen, the pen cap 20 can be rotated to align with the charging interface part 11. The magnetic component will help the pen cap 20 to be fixed in this position. If the user wants to view the information on the capacitive pen (such as a serial number or other identification information), the pen cap 20 can be rotated to align with the identification part 12. Specifically, the first magnetic component 30 is located in the pen cap 20, and the second magnetic component 40 is located on the pen tube 10, and the two are arranged oppositely. The two magnetic components can be made of permanent magnets or devices containing electromagnetic coils that can generate a stable magnetic field. When the pen cap 20 rotates relative to the pen barrel 10, the relative position between the two magnetic components will also change. If the corresponding faces of the two magnetic components are of the same polarity (for example, both are N poles or both are S poles), a magnetic repulsion force will be generated between them. When the user starts to rotate the pen cap 20, the distance and angle between the two magnetic components will change. When the pen cap 20 rotates to a certain angle, the magnetic repulsion force will become the largest, which will prompt the pen cap 10 to continue rotating, that is, the preset first position or second position. Once the pen cap 20 reaches the first position or the second position, the magnetic repulsion between the magnetic components will keep the pen cap 10 in this position until the user manually rotates the pen cap 10 again. It is understandable that the magnetic component can be designed as a plurality of small magnets or a magnet that is a whole but has multiple magnetic pole regions. For example, the first magnetic component 30 in the pen cap 20 can be a series of small magnets arranged at intervals, and the second magnetic component 40 on the pen barrel 10 can also be of a similar design. With this design, users can align different parts of the pen barrel, such as the charging port or identification information, with a simple rotation motion, without the need for complicated operating steps. Using magnetic repulsion to assist positioning can reduce mechanical wear and extend the service life of the capacitive pen. The magnetic repulsion between the magnetic components can ensure that the pen cap 10 can be accurately positioned at a preset position during rotation, avoiding inaccurate positioning due to improper manual operation. Magnetic repulsion can help users more easily rotate the pen cap 10 to the desired position, reducing the difficulty of manual alignment and improving the convenience of operation.

[0051] Reference Figure 1 to Figure 14In an embodiment of the present invention, the pen cap 20 includes a pen cap body 22 and a rotating member 23, the rotating member 23 is transmission-connected to the pen cap body 22, the first magnetic component 30 is disposed on the rotating member 23, the pen cap body 22 drives the rotating member 23 to rotate, and links the first magnetic component 30 to move relative to the second magnetic component 40, so that the pen cap 20 is switched between the first position and the second position.

[0052] A rotating member 23 is provided, and a first magnetic component 30 is provided on the rotating member 23. There is a transmission connection between the pen cap body 22 and the rotating member 23, so that when the pen cap body 22 rotates, the rotating member 23 will be driven to rotate together, and then the first magnetic component 30 will be driven to move relative to the second magnetic component 40, and finally the pen cap 10 is switched between the first position and the second position. Specifically, the pen cap body 22 is in the default first position, at which time the display hole 21 is aligned with the identification part 12 on the pen tube. When the user rotates the pen cap body 22, the rotating member 23 will also rotate due to the transmission connection between the pen cap body 22 and the rotating member 23. As the rotating member 23 rotates, the first magnetic component 30 also starts to move relative to the second magnetic component 40. When the pen cap 20 rotates to a certain angle, the magnetic repulsion between the first magnetic component 30 and the second magnetic component 40 will become the largest, which will prompt the pen cap 10 to continue to rotate, that is, the preset first position or the second position. The rotating member 23 acts as an intermediate medium to reduce the direct contact and friction between the pen cap body 22 and the pen tube, thereby reducing wear. The rotating member 23 is an independent component and can be easily replaced if it fails or wears out, without replacing the entire pen cap 10, thereby reducing maintenance costs.

[0053] Reference Figure 1 to Figure 14 In the embodiment of the present invention, the first magnetic component 30 includes a first magnetic member 31 and a second magnetic member 32, and the first magnetic member 31 and the second magnetic member 32 are disposed opposite to the rotating member 23;

[0054] The second magnetic assembly 40 includes a third magnetic component 41 and a fourth magnetic component 42, and the third magnetic component 41 and the fourth magnetic component 42 are disposed opposite to the pen tube 10;

[0055] Among them, there is a magnetic repulsion relationship between the corresponding ends of the first magnetic component 31 and the second magnetic component 32, between the corresponding ends of the third magnetic component 41 and the fourth magnetic component 42, between the corresponding ends of the first magnetic component 31 and the third magnetic component 41, and between the corresponding ends of the second magnetic component 32 and the fourth magnetic component 42.

[0056] The first magnetic assembly 30 includes two magnetic parts: a first magnetic part 31 and a second magnetic part 32; the second magnetic assembly 40 also includes two magnetic parts: a third magnetic part 41 and a fourth magnetic part 42. These magnetic parts are respectively arranged on the rotating part 23 and the pen tube 10, and the corresponding ends thereof present a magnetic repulsion relationship. Specifically, the pen cap body 21 is in the default first position, at which time the display hole 21 is aligned with the identification part 12 on the pen tube. When the user rotates the pen cap body 21, the pen cap body 21 drives the rotating part 23 to rotate together, so the first magnetic part 31 and the second magnetic part 32 also rotate accordingly. As the rotating part 23 rotates, the relative positions of the first magnetic part 31 and the second magnetic part 32 and the third magnetic part 41 and the fourth magnetic part 42 change. Due to the magnetic repulsion between the magnetic parts, when the rotating part 23 rotates to a certain angle, the magnetic repulsion will become the maximum, which will prompt the pen cap 10 to continue to rotate, that is, the preset first position or the second position. Multiple magnetic parts can provide a more stable magnetic repulsion effect, making it easier for the pen cap to remain in a predetermined position when rotating, reducing the shaking or deviation that may be caused by a single magnetic part. When the rotating member 23 reaches a new position, the mutual repulsion between the multiple magnetic parts will keep the rotating member 23 in this position, and the display hole 21 will automatically align with the charging interface part 11 or the identification part 12.

[0057] Reference Figure 1 to Figure 14 In the embodiment of the present invention, the rotating member 23 has a first mounting groove 24 and a second mounting groove 25, the first mounting groove 24 and the second mounting groove 25 are located on the same circumferential surface of the rotating member 23, and are symmetrically arranged relative to the central axis of the rotating body 231, the outer circumferential surface of the first magnetic member 31 is limitedly matched with the inner circumferential surface of the first mounting groove 24, and the outer circumferential surface of the second magnetic member 32 is limitedly matched with the inner circumferential surface of the second mounting groove 25.

[0058] By setting symmetrical mounting grooves, it can be ensured that the magnetic parts will not loosen or shift during the rotation process, providing a stable installation environment. It can be understood that the symmetrically arranged mounting grooves can ensure that the positions of the first magnetic part 31 and the second magnetic part 32 on the rotating part 23 are precisely aligned, avoiding functional problems caused by installation position deviations. The symmetrical arrangement helps to balance the center of gravity of the rotating body and reduce vibration or noise caused by imbalance during rotation. The symmetrical mounting groove design makes the installation of the magnetic parts more convenient and reduces the difficulty of position adjustment during assembly. Through limit fit, the magnetic parts fit tightly with the mounting grooves, reducing looseness caused by vibration or long-term use, and enhancing the reliability of the system.

[0059] Reference Figure 1 to Figure 14In the embodiment of the present invention, the pen tube 10 includes a pen tube body 13, a first limiting member 14 and a second limiting member 15. The first limiting member 14 and the second limiting member 15 are relatively arranged at one end of the pen tube body 13 close to the opening. The first limiting member 14 and the second limiting member 15 are extended along the circumference of the pen tube body 13. The first limiting member 14 and the second limiting member 15 are surrounded to form a movement space 16. The magnetic rotating member 23 is rotatably arranged in the movement space 16.

[0060] This solution forms a movement space 16 by setting a first limiter 14 and a second limiter 15 on the pen barrel body, and the magnetic rotating member 23 is located in this space and can rotate therein. The two limiters ensure that the rotation of the magnetic rotating member 23 will not exceed the predetermined range, thereby ensuring the positioning accuracy of the pen cap 20 during rotation. The design of the first limiter 14 and the second limiter 15 can limit the movement range of the magnetic rotating member 23, ensuring that the rotating member 23 can only rotate within the predetermined range to prevent over-rotation or misoperation. The first limiter 14 and the second limiter 15 can ensure that the rotating member 23 can accurately reach the preset position during rotation, avoiding inaccurate positioning caused by excessive or insufficient rotation. Through the constraints of the first limiter 14 and the second limiter 15, the shaking of the rotating member 23 during rotation can be reduced, and the stability of the entire system during use can be improved. The first limiter 14 and the second limiter 15 can prevent the rotating member 23 from excessively rotating and causing damage to the internal structure, thereby playing a protective role. The design of the first stopper 14 and the second stopper 15 allows the user to feel a clear boundary when rotating the pen cap, providing a better operating experience. In this embodiment, the projection surfaces of the first stopper 14 and the second stopper 15 on the mounting surface of the pen tube body 13 are arranged perpendicular to each other. When the pen cap 20 is rotated to a certain angle, that is, when it is rotated to 45°, when the first magnetic member 31 and the second magnetic member 32 are directly opposite each other, the magnetic repulsion will become the maximum, which will prompt the pen cap 10 to continue to rotate to 90°, that is, the preset first position or second position. It can be understood that the first stopper 14 and the second stopper 15 can be protrusions extending along the circumference of the pen tube body 13, these protrusions can be solid or hollow, and the material can be plastic or metal. Or, the first stopper 14 and the second stopper 15 can be baffles perpendicular to the axis of the pen tube, and the baffle can be a single piece or a combination of multiple pieces to form a space surrounding the rotating member.

[0061] Reference Figure 1 to Figure 14In the embodiment of the present invention, the pen tube 10 further includes a third limiting member 17, which is disposed on the pen tube body 13, and is located between the first limiting member 14 and the second limiting member 15. The third limiting member 17 is extended along the axial direction of the pen tube body 13, and a limiting step 26 is provided on the inner circumferential wall of the rotating member 23 close to one end of the pen tube 10, and the limiting step 26 is formed along the inner circumferential wall of the rotating member 23. The third limiting member 17 is installed on the limiting step 26, and the rotating member 23 is rotatably sleeved on the third limiting member 17.

[0062] When the rotating member 23 rotates to the predetermined position, the magnetic repulsion between the magnetic members keeps the rotating member 23 in this position, and the cooperation between the third stopper 17 and the stopper step 26 ensures that the rotating member 23 does not move axially. Through the cooperation between the third stopper 17 and the stopper step 26, the rotating member 23 can be prevented from axial displacement during the rotation process, thereby improving the stability of the system. The design of the stopper step 26 can prevent the rotating member 23 from moving up and down during the rotation process, thereby avoiding functional failure caused by axial movement. The cooperation between the third stopper 17 and the stopper step 26 can ensure that the rotating member 23 can be accurately positioned at the predetermined position during rotation. It is understandable that the third stopper 17 can be a columnar structure, whose diameter is slightly smaller than the inner diameter of the stopper step 26, to ensure that the stopper can be smoothly installed on the stopper step 26 and can rotate freely. Or, the third stopper 17 can be an annular structure, whose inner diameter matches the inner diameter of the rotating member 23, to ensure that the stopper can be installed on the stopper step 26 and provide sufficient axial support.

[0063] Reference Figure 1 to Figure 14 In the embodiment of the present invention, the rotating member 23 includes a rotating body 231 and a rotating body 232, the first magnetic member 31 and the second magnetic member 32 are relatively arranged on the rotating body 231, the rotating body 232 is arranged on a side of the rotating body 231 close to the movement space 16, the rotating body 232 includes a disk 233 with a hole in the center, the edge of the disk 233 is provided with a first arm-like structure 234 and a second arm-like structure 235 extending outward, the first arm-like structure 234 and the second arm-like structure 235 are extended in opposite directions, when the rotating body 231 rotates, the rotating body 232 rotates in the circumferential direction of the movement space 16, the first arm-like structure 234 is abutted and positioned with the first limiting member 14, and the second arm-like structure 235 is abutted and positioned with the second limiting member 15, so as to limit the rotation range of the rotating body 231.

[0064] By cooperating the first arm-like structure 234 and the second arm-like structure 235 with the first stopper 14 and the second stopper 15, the rotation range of the rotating body 231 can be precisely controlled to ensure that the rotating body 231 can only rotate within a predetermined angle range. Furthermore, the contact between the arm-like structure and the stopper can prevent the rotating body from over-rotating, thereby avoiding damage or malfunction caused by excessive rotation. It is understandable that the rotating body 231 is in a default position, at which time the arm-like structure is not in contact with the stopper. The user rotates the pen cap 10, driving the rotating body 231 and the rotating body 232 to rotate together. As the rotating body 231 rotates, the first arm-like structure 234 and the second arm-like structure 235 on the rotating body 232 will gradually approach the first stopper 14 and the second stopper 15. When the first arm-like structure 234 contacts the first stopper 14 or the second arm-like structure 235 contacts the second stopper 15, the rotating body 231 will stop rotating and remain at a preset position. The user can reversely rotate the pen cap 10 to return the rotating body 231 to the initial position or other preset positions. The disc 233 has a hole in the center, which can be put on the rotating body 231 to ensure that the two rotate synchronously. The first arm structure 234 and the second arm structure 235 can extend outward from the edge of the disc 233 and are arranged in opposite directions, so that the rotating body 231 can contact the limiter when rotating to limit the rotation range.

[0065] Reference Figure 1 to Figure 14 In the embodiment of the present invention, the movement space 16 includes a first limiting space and a second limiting space, the first limiting member 14 has a first side wall 141 and a second side wall 142 arranged opposite to the first side wall, the second limiting member 15 has a third side wall 151 and a fourth side wall 152 arranged opposite to the third side wall, the first side wall 141 and the third side wall 151 are arranged to form the first limiting space, the second side wall 142 and the fourth side wall 152 are arranged to form the second limiting space, when the rotating body 231 rotates, the first arm-like structure 234 can be abutted and positioned with the first side wall 141 and the third side wall 151, and the second arm-like structure 235 can be abutted and positioned with the second side wall 142 and the fourth side wall 152.

[0066] The rotating body 231 is in the default position, and the first arm-shaped structure 234 and the second arm-shaped structure 235 are not in contact with the limiting member. The user rotates the pen cap 10, driving the rotating body 231 and the rotating body 232 to rotate together. As the rotating body 231 rotates, the first arm-shaped structure 234 gradually approaches the first side wall 141 and the third side wall 151, and the second arm-shaped structure 235 gradually approaches the second side wall 142 and the fourth side wall 152. When the first arm-shaped structure 234 contacts the first side wall 141 and the third side wall 151, the rotating body 231 stops rotating and is positioned in the first limiting space; when the second arm-shaped structure 235 contacts the second side wall 142 and the fourth side wall 152, the rotating body 231 stops rotating and is positioned in the second limiting space. Each limiting space has a dedicated side wall to ensure that the rotating body 231 can be accurately aligned when rotating. When the first arm-shaped structure 234 and the second arm-shaped structure 235 contact the corresponding side wall, a clear positioning point can be provided. The design of two limit spaces can reduce positioning errors and ensure that each rotation can accurately reach the predetermined position.

[0067] Reference Figure 1 to Figure 14 In the embodiment of the present invention, a limiting structure 18 is provided in the pen tube body 13, and an annular boss 27 is provided along the inner circumferential wall of the display hole 21. The side walls of the limiting structure 18 are symmetrically formed with a first installation space 181 and a second installation space 182 with the inner side wall of the pen tube body 13, respectively. The first installation space 181 is used to limit the third magnetic component 41, and the second installation space 182 is used to limit the fourth magnetic component 42. Both sides of the annular boss 27 have a first limiting portion 271 and a second limiting portion 272 extending toward the inner wall of the pen tube body 13. The first limiting portion 271 is used to abut against the bottom of the third magnetic component 41, and the second limiting portion 272 is used to abut against the bottom of the fourth magnetic component 42.

[0068] The limiting structure 18 is a structure arranged inside the pen tube body 13, and its main function is to form an installation position to fix the magnetic component. The limiting structure 18 can be an independent component or a part of the pen tube body 13, which is integrally formed by processing or mold forming. The side wall of the limiting structure 17 and the inner side wall of the pen tube body 13 symmetrically form a first installation space 181 and a second installation space 182. This means that on both sides of the limiting structure 18, the inner side wall of the pen tube body 13 leaves two symmetrically arranged spaces for installing magnetic components. On one side of the limiting structure 18, the first installation space 181 left by the inner side wall of the pen tube body 13 should be sufficient to accommodate the third magnetic component 41, and ensure that the magnetic component can abut against the first limiting portion 271 of the annular boss 27 to avoid falling along the axial direction of the pen tube body 13. The second installation space 182 is on the other side of the limiting structure 18, and the space left by the inner side wall of the pen barrel body 13 should be sufficient to accommodate the fourth magnetic member 42, and ensure that the magnetic member can abut against the second limiting portion 272 of the annular boss 27 to avoid falling along the axial direction of the pen barrel body 13. It is understandable that the limiting structure 17 can be designed as a central columnar structure, with a symmetrical plane or groove on each side, forming the first installation space 181 and the second installation space 182 with the inner wall of the pen barrel body 13. It is understandable that the space left by the inner side wall of the pen barrel body 13 on both sides of the limiting structure 18 can be designed to match the magnetic member, such as a circular or rectangular groove, to ensure that the magnetic member can be firmly placed therein.

[0069] Reference Figure 1 to Figure 14 In the embodiment of the present invention, a first mounting hole 25 and a second mounting hole 26 are formed at one end of the pen cap body 22 away from the opening, and a first limiting column 28 and a second limiting column 29 are formed at one end of the rotating member 23 away from the opening. The first limiting column 28 passes through the first mounting hole 25, and the second limiting column 29 passes through the second mounting hole 26.

[0070] By passing the first limiting column 28 and the second limiting column 29 through the first mounting hole 25 and the second mounting hole 26, the rotating member 23 can be prevented from moving in the axial direction (i.e., the length direction of the pen tube 10), ensuring that the rotating member 23 remains stable during rotation. The cooperation between the limiting column and the mounting hole can ensure that the rotating member 23 can be accurately positioned when rotating to a predetermined position, avoiding inaccurate positioning due to looseness. It can be understood that the first limiting column 28 and the second limiting column 29 can be designed as a columnar structure, the diameter of which is slightly smaller than the diameter of the first mounting hole 25 and the second mounting hole 26, so as to ensure that the first limiting column 28 and the second limiting column 29 can smoothly pass through the first mounting hole 25 and the second mounting hole 26. The first mounting hole 25 and the second mounting hole 26 can be designed as a circular or rectangular hole, ensuring that the first limiting column 28 and the second limiting column 29 can stably pass through and limit the axial movement of the rotating member 23.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
