Description

Technical Field

[0001] This utility model relates to writing instruments, specifically a rotary tactile feedback mechanism and a rotary lead-out pen. Background Technology

[0002] There are many pens on the market with replaceable refills, such as replaceable pencil leads and crayon leads. In actual use, these refills generally need to be pushed out to maintain a certain pen tip length and ensure writing quality.

[0003] Currently, the most common solution is to use a rotating pen to extend the lead. A reference to a rotating pen disclosed in Chinese Utility Model Patent No. CN212446854U is that rotating the pen causes one component (the adjustment part in the published document) to extend the lead. This solution provides a rotating lead extension structure. However, in certain usage scenarios, such as when artists are sketching, the pen cap (the component that drives the lead extension after rotation) may press against the palm of the hand. Accidental contact can cause the cap to rotate, leading to the lead retracting or extending, thus affecting the drawing process. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a rotary tactile feedback mechanism and a rotary lead-out pen, which can alleviate the problem of accidental extension or retraction of the pen lead due to accidental touch, and improve the stability of use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary tactile feedback mechanism, including a pen barrel and a rotating component. The rotating component is rotatably connected to the pen barrel, and the pen barrel is provided with a plurality of first mating components. The rotating component is provided with a plurality of second mating components. When the rotating component rotates by a preset angle, the first mating components and the second mating components cooperate to generate a vibration. The first mating components and the second mating components also cooperate to form a rotational damping of the rotating component.

[0006] As a further improvement of this utility model, the end of the pen barrel corresponding to the rotating part is provided with a socket, the rotating part is inserted into the socket, and forms a rotatable connection with the socket.

[0007] As a further improvement of this utility model, the first mating member is disposed on the inner wall of the insertion hole, and the second mating member is disposed on the outer surface of the rotating member. When the rotating member is inserted into the insertion hole at a preset position, the positions of the first mating member and the second mating member correspond.

[0008] As a further improvement of this utility model, the first mating member is a first protrusion provided on the inner wall of the insertion hole, and the contact surface of the first protrusion for mating with the second mating member is arc-shaped; the second mating member is a second protrusion provided on the outer surface of the rotating member.

[0009] As a further improvement of this utility model, the number of the second mating parts is multiple, and the spacing between adjacent second mating parts is at least sufficient for the first mating part to be embedded, thereby generating a vibration.

[0010] As a further improvement of this utility model, the number of the second mating parts is multiple, and they are evenly distributed circumferentially on the outer surface of the rotating part. The spacing between adjacent second mating parts is at least enough to allow some of the first mating parts to be embedded, thus creating a vibration.

[0011] As a further improvement of this utility model, the second mating component has chamfers on both sides of the end facing the pen barrel, and the adjacent second mating components are flared by chamfers.

[0012] As a further improvement of this utility model, the number of the first mating parts is 1 to 8.

[0013] As a further improvement of this utility model, the first mating part is integrally formed with the pen barrel, and / or the second mating part is integrally formed with the rotating part.

[0014] A rotating pen with a refill is also provided, comprising a pen barrel, an adjusting member installed inside the pen barrel, a refill connected to the adjusting member, a rotating member rotatably connected to the pen barrel, and a linkage member connected to the rotating member for driving the adjusting member to rotate; the inner wall of the pen barrel is provided with threads, and the adjusting member is threadedly engaged with the inner wall of the pen barrel; the rotating member and the pen barrel cooperate to form a rotating tactile feedback mechanism, which adopts any of the above-described rotating tactile feedback mechanisms; when the rotating member rotates, it drives the adjusting member to rotate through the linkage member, and drives the adjusting member to move axially through the threaded engagement between the adjusting member and the inner wall of the pen barrel, so as to drive the refill to extend or retract.

[0015] The beneficial effects of this utility model are that, through the cooperation of the first mating part on the pen barrel and the second mating part on the rotating part, a vibration is generated after the rotating part rotates at a preset angle, which allows the user to clearly perceive the rotation position and helps to control the rotation level. At the same time, the rotation damping formed by the cooperation of the two can alleviate the situation where the rotating part rotates due to accidental touch, thereby improving the problem of the pen tip accidentally extending or retracting due to accidental touch and improving the stability of use.

[0018] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0019] Reference Figure 1-6 As shown, this embodiment provides a rotary haptic feedback mechanism, including a pen barrel 1 and a rotating component 2. The rotating component 2 is rotatably connected to the pen barrel 1, and the pen barrel 1 is provided with a plurality of first mating components 11. The rotating component 2 is provided with a plurality of second mating components 21. When the rotating component 2 rotates by a preset angle, the first mating components 11 and the second mating components 21 cooperate to generate a vibration, and the first mating components 11 and the second mating components 21 also cooperate to form the rotational damping of the rotating component 2.

[0020] The circumferentially rotatable connection between the rotating component 2 and the pen barrel 1 can be achieved through a plug-in fit. For example, one end of the rotating component 2 can be inserted into a pre-set mounting hole in the pen barrel 1, with a small gap between them to meet the circumferential rotation requirements. The first mating component 11 can be configured as a protrusion or groove structure, and the second mating component 21 can be configured as a corresponding groove or protrusion structure to ensure that the two can cooperate with each other. Alternatively, a spring can be used to engage with the groove / protrusion. When the user rotates the rotating component 2, the first mating component 11 and the second mating component 21 are in continuous contact and generate friction. This friction forms rotational damping, which can reduce the probability of the rotating component 2 rotating due to slight accidental contact. When the rotating component 2 rotates to a preset angle (such as the first mating component 11 moving from one side of the second mating component 21 to the other side), the engagement state of the two changes (such as the protrusion coming out of the groove and embedding into the adjacent groove). This change will generate a slight vibration and transmit it to the user's hand, allowing the user to clearly perceive the rotation position, thereby avoiding the rotating component 2 rotating due to accidental contact and improving the problem of the pen refill 4 accidentally extending or retracting.

[0021] To facilitate a stable rotatable connection between the rotating component 2 and the pen barrel 1, in one optional embodiment, the pen barrel 1 is provided with a socket 12 at the end corresponding to the rotating component 2, the rotating component 2 is inserted into the socket 12, and a rotatable connection is formed with the socket 12.

[0022] The insertion hole 12 at the end of the pen barrel 1 can be a circular hole structure. The end of the rotating component 2 that is inserted into the insertion hole 12 is set to be cylindrical and adapted to the insertion hole 12. The two achieve circumferential rotation through clearance fit. The depth of the insertion hole 12 can be designed according to the length of the rotating component 2. This connection structure is simple and reduces the possibility of weakened damping effect or insignificant vibration due to unstable connection, further improving the stability of use.

[0023] Specifically, the following methods can be selected for further optimization to ensure that the first mating part 11 and the second mating part 21 are stably mated. The first mating part 11 is set on the inner wall of the insertion hole 12, and the second mating part 21 is set on the outer surface of the rotating part 2. When the rotating part 2 is inserted into the insertion hole 12 at a preset position, the positions of the first mating part 11 and the second mating part 21 correspond.

[0024] The first mating component 11 can be circumferentially spaced along the inner wall of the insertion hole 12, while the second mating component 21 is correspondingly disposed on the outer surface of the portion of the rotating component 2 inserted into the insertion hole 12. The preset position of the rotating component 2 inserted into the insertion hole 12 can be limited by an annular step provided inside the insertion hole 12 or by the end of the pen barrel 1. When the rotating component 2 is inserted into the correct position, the radial positions of the first mating component 11 and the second mating component 21 correspond. This positional correspondence design allows the first mating component 11 and the second mating component 21 to stably engage during the rotation of the rotating component 2, avoiding engagement failure due to positional misalignment. At the same time, placing the mating components between the inner wall of the insertion hole 12 and the outer surface of the rotating component 2 can utilize the structure of the insertion hole 12 to protect the mating components, reducing the impact of external dust and impurities on the mating components, extending the service life of the mating components, and ensuring long-term stability of damping and vibration effects.

[0025] In some options, in order to optimize the mating effect between the first mating part 11 and the second mating part 21, the first mating part 11 is a first protrusion provided on the inner wall of the insertion hole 12, and the contact surface of the first protrusion for mating with the second mating part 21 is arc-shaped; the second mating part 21 is a second protrusion provided on the outer surface of the rotating part 2.

[0026] The arc-shaped contact surface of the first protrusion can be designed as a circular arc, and its curvature can be adapted to the shape of the second protrusion. For example, when the second protrusion is set as a semi-circular protrusion, the curvature of the arc-shaped contact surface of the first protrusion is consistent with the curvature of the second protrusion. The second protrusion can also be designed with reference to... Figure 3As shown, a flat, raised structure is used. When the rotating component 2 rotates, the arc-shaped contact surface of the first raised component slides into contact with the surface of the second raised component. The arc-shaped structure reduces the frictional resistance between the two, making the rotation process smoother, avoiding any jamming, and improving the user experience. At the same time, the cooperation between the raised structures can form a stable frictional force, ensuring the effectiveness of rotational damping. Furthermore, when the first raised component slides from one side of the second raised component to the other, the transition of the arc-shaped contact surface makes the vibration feel softer and clearer (especially when the second raised component is a flat raised structure), making it easier for the user to perceive.

[0027] In order to make the vibration more obvious and the damping effect more stable, in one option, there are multiple second mating parts 21, and the spacing between adjacent second mating parts 21 is at least enough for the first mating part 11 to be embedded to form a vibration.

[0028] Multiple second mating parts 21 can be spaced apart along the outer surface of the rotating part 2. The spacing between adjacent parts can be designed according to a preset vibration frequency. For example, if a vibration is generated every 10° of rotation, the spacing between adjacent second mating parts 21 is set according to the arc length corresponding to this angle. When the user rotates the rotating part 2, the first mating part 11 will sequentially insert into the gap between adjacent second mating parts 21. During each insertion, the contact state between the first mating part 11 and the second mating part 21 changes, thereby generating a continuous and regular vibration. This allows the user to more accurately perceive the rotation angle and easily control the extension or retraction length of the pen refill 4. At the same time, the cooperation between multiple second mating parts 21 and the first mating part 11 can form continuous damping throughout the entire circumferential range of the rotating part 2, further reducing the probability of accidental rotation of the rotating part 2 and improving the stability of use. In this design, the number of first mating parts 11 can be reduced, for example, to 1 to 8, which can form stable damping and vibration feedback, and also avoid excessive damping that would increase the difficulty of rotation. Of course, it is also possible to design in reverse, with multiple first mating parts 11 and a reduced number of second mating parts 21.

[0029] Specifically, the second mating parts 21 can be evenly distributed circumferentially to further optimize the effect. There are multiple second mating parts 21, which are evenly distributed circumferentially on the outer surface of the rotating part 2. The spacing between adjacent second mating parts 21 is at least enough to allow some of the first mating parts 11 to be embedded, thus creating a vibration.

[0030] This uniformly distributed structure enhances the feel of rotating the rotating part 2 during rotation; the uniformly distributed second mating part 21 allows the user to feel a vibration every time they rotate the same angle, making the perception of the rotation angle more accurate. This is especially suitable for scenarios such as drawing where precise control of the pen tip 4's extension length is required, further improving the product's adaptability.

[0031] In order to facilitate the insertion of the first mating part 11 into the adjacent second mating parts 21, in some options, the second mating parts 21 are provided with chamfers 22 on both sides of the end facing the pen barrel 1, and the adjacent second mating parts 21 are flared by the chamfers 22.

[0032] The chamfer 22 of the second mating part 21 facing the pen barrel 1 can be designed with a 45° or 60° angle. The chamfers 22 of adjacent second mating parts 21 together form a flared structure. The opening size of the flared structure gradually decreases from the outside to the inside and matches the size of the first mating part 11. This structure facilitates the insertion between the rotating part 2 and the pen barrel 1, and has a guiding and corrective function. It can alleviate the problem of interference between the first mating part 11 and the second mating part 21 during the insertion process, improve installation efficiency, and facilitate reassembly after the user replaces the pen refill 4.

[0033] To accommodate different damping and vibration feedback requirements, in one optional scheme, the number of first mating parts 11 is 1 to 8. This number can satisfy sufficient damping and vibration feedback requirements; exceeding this number may result in excessive damping force, affecting the user's normal rotation of the rotating part 2 and reducing the user experience.

[0034] In order to simplify the manufacturing process and improve the connection strength of components, in some options, the first mating part 11 is integrally formed with the pen barrel 1, and / or the second mating part 21 is integrally formed with the rotating part 2.

[0035] The integral molding of the first mating part 11 and the pen barrel 1 can be achieved by injection molding. For example, when the pen barrel 1 is made of plastic, the pen barrel 1 with the first mating part 11 can be directly injection molded using a mold. The integral molding of the second mating part 21 and the rotating part 2 can also be achieved by the same process. The integral molding structure eliminates the need for additional assembly of mating parts, reducing production steps and assembly costs.

[0036] Based on the above-mentioned rotary tactile feedback mechanism, this embodiment also provides a rotary lead-out pen, including a pen barrel 1, an adjusting member 3 installed inside the pen barrel 1, a lead 4 connected to the adjusting member 3, a rotating member 2 rotatably connected to the pen barrel 1, and a linkage member 5 connected to the rotating member 2 for driving the adjusting member 3 to rotate; the inner wall of the pen barrel 1 is provided with threads, and the adjusting member 3 is threadedly engaged with the inner wall of the pen barrel 1; the rotating member 2 and the pen barrel 1 cooperate to form a rotary tactile feedback mechanism, which adopts any of the above-mentioned rotary tactile feedback mechanisms. When the rotating member 2 rotates, it drives the adjusting member 3 to rotate through the linkage member 5, and drives the adjusting member 3 to move axially through the threaded engagement between the adjusting member 3 and the inner wall of the pen barrel 1, so as to drive the lead 4 to extend or retract.

[0037] The adjusting component 3 can be configured as a cylindrical structure, with an external thread on its outer surface that matches the thread on the inner wall of the pen barrel 1. The pen core 4 is inserted into the adjusting component 3 by interference fit or snap-fit. The linkage component 5 can adopt a protrusion and groove matching structure. For example, a protrusion is provided at the end of the rotating component 2 that is inserted into the pen barrel 1, and an axial groove that matches the protrusion is provided at one end of the adjusting component 3. The protrusion is embedded in the groove to ensure that the adjusting component 3 can rotate synchronously through the protrusion when the rotating component 2 rotates. When the user rotates the rotating component 2, the rotating component 2 first forms damping through the first mating part 11 and the second mating part 21 of the rotary haptic feedback mechanism, reducing the probability of accidental rotation. Simultaneously, the rotating component 2 drives the adjusting component 3 to rotate via the linkage 5. Under the action of the threads on the inner wall of the pen barrel 1, the adjusting component 3 converts circumferential rotation into axial movement, thereby extending or retracting the pen tip 4. During rotation, the vibration generated by the rotary haptic feedback mechanism allows the user to perceive the axial movement distance of the adjusting component 3, thus more precisely controlling the extension length of the pen tip 4. This is especially suitable for scenarios where the palm rests against the rotating component 2 while drawing, effectively improving the problem of accidental movement of the pen tip 4 due to accidental touch and enhancing reliability. The structure of the linkage 5 can be as follows: Figure 5 and 6 The tubular component shown can also adopt the solution used in the prior art mentioned in the background section.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
