Description

Pen tip structure and smart pen Technical Field

[0001] The present application relates to the technical field of touch devices, and in particular to a pen tip structure and a smart pen. Background Art

[0002] A stylus (or stylus pen) is a pen-shaped tool used to input commands into touch-enabled devices such as interactive tablets. Users can use the stylus to click on the touch panel to perform a series of touch operations such as file selection and drawing, to assist navigation or provide higher operational accuracy.

[0003] A stylus is generally composed of a pen tip (the head portion) and a pen barrel (the body portion). The pen tip is used to contact a touch device and perform touch operations on the touch device, while the pen barrel is primarily used for holding and installing related components (such as a control circuit board, battery, and charging port). To facilitate assembly and disassembly of the stylus, the pen tip and pen barrel generally utilize a snap-on structure with elastic reset capabilities, such as an elastic arm, to achieve detachable assembly and coordination. However, the assembly method using an elastic snap-on structure is difficult to assemble and disassemble and is also susceptible to structural damage due to factors such as material fatigue. The connection between the pen tip and pen barrel is easily damaged or failed due to damage to the elastic snap-on structure, resulting in a short assembly and disassembly lifespan, which ultimately affects the user experience.

[0004] Summary of the Invention

[0005] The purpose of this application is to provide a pen tip structure and a smart pen to solve the problem of poor reliability of the connection structure between the pen tip and the pen body of the smart pen.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] In a first aspect, a pen tip structure is provided, comprising:

[0008] The pen tip is hollow inside to form a mounting cavity, and one end of the pen tip is provided with a mounting opening communicating with the mounting cavity;

[0009] a locking assembly; and

[0010] The trigger assembly, the locking assembly and the trigger assembly can be movably arranged in the mounting cavity, the first end of the trigger assembly is at least partially exposed from the pen tip, and the second end of the trigger assembly acts on the locking assembly and can drive the locking assembly to move relative to the pen tip, so that the locking assembly can be installed and cooperated with the pen body of the stylus pen, or detached from the pen body of the stylus pen.

[0011] In a second aspect, a smart pen is provided, comprising:

[0012] a pen body, wherein a mounting structure is provided on an inner wall of the pen body; and

[0013] As described in the first aspect, the pen tip structure is mounted and matched with the pen body through the locking assembly.

[0014] The beneficial effect of the present application is that the pen tip structure is provided with a matching locking component and trigger component inside the pen tip, so that the locking component can move relative to the pen tip under the drive of the trigger component, so that the pen tip structure can be installed and matched with the pen body of the smart pen through the locking component, or detached from the pen body of the smart pen.

[0015] In smart pen applications, this pen tip structure achieves its proper fit with the pen body, not through material properties, but rather through the relative positional shifting between the locking assembly and the pen tip. Consequently, the pen tip structure is less susceptible to connection failure due to material fatigue of the locking assembly, effectively extending the lifespan of the connection between the pen tip structure and the pen body, making the smart pen product structure more stable and durable. Furthermore, the movement of the locking assembly relative to the pen tip is controlled by a trigger assembly, which is at least partially exposed from the pen tip for easier user operation. This makes assembly and disassembly of the pen tip structure quick, simple, and easy to implement, effectively enhancing the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0031] In the description of this application, unless otherwise specified or limited, the terms "connected" and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0032] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0033] A stylus (or stylus pen) is a pen-shaped tool used to input commands into touch-enabled devices such as interactive tablets. Users can use the stylus to click on the touch panel to perform a series of touch operations such as file selection and drawing, to assist navigation or provide higher operational accuracy.

[0034] As can be seen from the background technology, the stylus pen is generally assembled from a pen tip (pen head part) and a pen barrel part (pen body part). The pen tip is used to contact the touch device and be located on the touch device to perform related touch operations, while the pen barrel part is mainly used to provide users with grip and use, as well as to install related devices (such as the control circuit board 90, the battery 80, the charging port, etc.). In order to facilitate the disassembly and assembly of the stylus pen, the pen tip and the pen barrel part generally adopt a snap-on structure with elastic reset capability such as an elastic arm to achieve detachable assembly and coordination. However, the assembly method using the elastic snap-on structure is difficult to disassemble and assemble. Since the current snap-on structures such as elastic arms are all made of plastic materials, the plastic materials gradually lose their elasticity after a long period of elastic extrusion and reset, causing material fatigue and damage. The connection between the pen tip and the pen barrel part is easily damaged due to damage to the elastic snap-on structure, and the disassembly and assembly life of the structure is short, which ultimately affects the user experience. To this end, in the process of solving the aforementioned technical problems, the inventors found that if an elastic arm is made of a material with better fatigue resistance, such as metal, etc., although the service life of the elastic arm can be extended, it will cause the production process to be complicated and the cost to increase. In addition, it cannot solve the problem that the pen tip and the pen barrel are difficult to disassemble and assemble. Therefore, the inventors provide another solution, which uses a movable mechanical structure to achieve the locking, fixation and splitting and separation of the pen tip and the pen barrel. Since the fixing structure at the connection between the pen tip and the pen barrel has two forms due to the use of mechanical movement, and the fixation is not achieved by the elasticity of the material itself, long-term disassembly will not cause damage to the fixing structure. At the same time, a button for the user to operate conveniently is provided on the outer surface of the pen tip. The button is linked to the aforementioned movable mechanical structure, so that the mechanical structure can be controlled to fix and separate the pen tip and the pen barrel, achieving the effect of easy disassembly and assembly of the stylus pen, greatly improving the user experience.

[0035] This application proposes a pen tip structure primarily for stylus applications. It can be used on smart devices with capacitive touch or infrared touch screens, such as interactive tablets for everyday use and professional drawing tablets. This pen tip structure addresses the aforementioned technical issues by improving the pen tip structure and optimizing the assembly structure between the pen tip structure and the stylus body 60. This solves a series of issues in prior art, such as the low reliability of the connection between the pen tip structure and the stylus body 60.

[0036] Referring to Figures 1-7 , the pen tip structure of this embodiment includes a pen tip 10, which is used to mount and support the tip portion 70 of the stylus. During stylus use, the tip portion 70 contacts a touch device and performs corresponding touch operations. A mounting cavity 121 is formed within the interior of the pen tip 10. This cavity 121 provides a mounting location for components that can be assembled and disassembled from the stylus body 60. When the pen tip 10 is assembled with the body 60, a mounting opening 122 is defined at one end of the pen tip 10, adjacent to the body 60, and communicates with the mounting cavity 121. This allows the tip portion 70 to engage with the body 60 through the mounting opening 122.

[0037] In one embodiment, a mounting portion 114 for mounting the nib 70 is provided at one end of the pen tip 10, facing away from the pen body 60 or the mounting opening 122. The mounting portion 114 can be configured as a slot, insert, or snap, etc., to facilitate inter-component mounting and mating, depending on the stylus structure or the structural adaptability of the nib 70. In this embodiment, the mounting portion 114 is configured as a slot provided in the pen tip 10, through which the nib 70 is inserted and mated. Depending on the stylus's touch mode, the nib 70 can selectively be electrically connected to the circuit board 90 within the stylus or simply physically mated to the pen tip 10.

[0038] Continuing with the above-mentioned embodiment of the pen tip 10 structure, in order to enable the pen tip assembly and the stylus pen body 60 to be detachably mounted, a locking assembly 20 and a trigger assembly 30 are further provided within the mounting cavity 121 of the pen tip contact member. Both the locking assembly 20 and the trigger assembly 30 can be positioned within the mounting cavity 121 and move relative to the pen tip 10. A first end of the trigger assembly 30 is at least partially exposed from a side of the pen tip 10 (i.e., the first end of the trigger assembly 30 is at least partially exposed from a side wall between opposite ends of the pen tip 10 to the outside of the pen tip 10), providing an operating position for a user to manipulate the trigger assembly 30. The locking assembly 20 is at least partially exposed from the outside of the pen tip 10 through the mounting opening 122. Movement of the locking assembly 20 relative to the pen tip 10 allows the pen tip structure and the stylus pen body 60 to be disassembled and assembled according to the current relative position of the locking assembly 20 and the pen tip 10.

[0039] For example, the locking assembly 20 can be movable between an expanded or retracted position relative to the mounting opening 122, or between an extended or retracted position relative to the mounting opening 122, thereby locking or unlocking the stylus body 60 in at least two positions. It should be understood that regardless of whether the locking assembly 20 adopts the aforementioned or any other method of relative movement with the pen tip 10, when the pen tip structure and the stylus body 60 are mounted and engaged, the locking assembly 20 is in a position capable of limiting engagement with the stylus body 60. Correspondingly, when the pen tip structure and the stylus body 60 are able to move toward or away from each other, the locking assembly 20 is in a position separated from the stylus body 60. For example, in an embodiment where the locking assembly 20 is extendable and retractable relative to the mounting opening 122, the locking assembly 20 can be extended to form a snap-fit, or other engagement with the stylus body 60. Furthermore, when the locking assembly 20 is retracted relative to the mounting opening 122, the locking assembly 20 and the stylus body 60 are released from this engagement. Conversely, the locking assembly 20 can be retracted relative to the mounting opening 122 to clamp onto a corresponding mating structure on the stylus body 60, and extended relative to the mounting opening 122 to release the stylus body 60. Furthermore, in an embodiment where the locking assembly 20 is extendable and retractable relative to the mounting opening 122, the locking assembly 20 can be extended relative to the mounting opening 122 to form a snap-fit, or other engagement with the stylus body 60. Furthermore, when the locking assembly 20 is retracted relative to the mounting opening 122, the locking assembly 20 and the stylus body 60 are released from this engagement. Conversely, the locking assembly 20 can also be retracted relative to the mounting opening 122 to constrain the pen tip 10 and the stylus pen body 60 by hooking, snapping, etc., and can be extended relative to the mounting opening 122 to release the stylus pen body 60.

[0040] In the above-described embodiment, the locking assembly 20 can be made of a rigid material with a certain structural strength, or a resilient material with a certain elastic return property, such as metal, rubber, or plastic. This is to ensure that, when the locking assembly 20 and the stylus body 60 are in a positionally restrained engagement, the locking assembly 20 is able to support and secure the pen tip 10 and the stylus body 60. It should be understood that, although the locking assembly 20 can be made of a resilient material with a certain elastic return property, it will not significantly deform relative to the pen tip 10 during disassembly and assembly with the stylus body 60. The locking assembly 20 primarily relies on the trigger assembly 30 to achieve relative movement with the pen tip 10, thereby changing the engagement with the stylus body 60, rather than relying on the elasticity of the locking assembly 20 material to lock the pen tip 10.

[0041] According to the above embodiment, the user can control the trigger assembly 30 through the first end of the trigger assembly 30 exposed on the outside of the pen tip 10, and the second end of the trigger assembly 30 acts on the locking assembly 20. When the user controls the trigger assembly 30 through the first end of the trigger assembly 30, the trigger assembly 30 can simultaneously drive the locking assembly 20 to move relative to the pen tip 10 through its second end during the process of moving relative to the pen tip 10, so that the locking assembly 20 can switch between the above-mentioned different position states, thereby realizing installation and cooperation with or separation from the stylus pen body 60.

[0042] By adopting the above-mentioned embodiment, the pen tip structure can be quickly disassembled and assembled with the stylus pen body 60 in the application of the stylus pen / smart pen. The user only needs to control the trigger component 30 according to the current needs (whether the pen tip structure needs to be installed on the stylus pen body 60, removed from the stylus pen body 60, or locked on the stylus pen body 60). This can change the relative position of the trigger component 30 and the pen tip 10, thereby changing the position state between the locking component 20 and the stylus pen body 60. The locking of the locking component 20 and the stylus pen body 60 is achieved by the locking component 20, the pen tip 10, and the pen body 60. 0, rather than relying on the material properties to achieve the installation fit between the two. Therefore, in the process of disassembling and assembling the pen tip structure, the relative deformation of the locking component 20 relying on the material properties and the pen tip 10 and the pen body 60 is much smaller than that of the solution implemented by means of an elastic snap-fit ​​structure, etc. The locking component 20 will not be over-extruded, so that its material is not prone to fatigue. Therefore, the pen tip structure adopting this solution is not prone to failure of the connection with the pen body 60 due to material fatigue of the locking component 20, which effectively extends the service life of the pen tip structure locking component 20, increases the number of disassembly and assembly between the pen tip structure and the pen body 60, and makes the smart pen product structure more stable and durable.

[0043] In addition, the movement of the locking assembly 20 relative to the pen tip 10 is controlled by the trigger assembly 30. The trigger assembly 30 is at least partially exposed from the pen tip 10 to facilitate user operation. The disassembly and assembly process of the pen tip structure is simple, fast and easy to implement, which effectively improves the user's experience. The trigger assembly 30 is exposed on the side between the first end and the second end of the pen tip 10. While facilitating user operation, when the user holds the stylus pen / smart pen, the hand is mainly held on the pen body 60, and it is not easy to accidentally touch or misoperate the trigger assembly 30. The effective connection between the pen tip structure and the pen body 60 can be well guaranteed when in use.

[0044] On the basis of the above embodiment, in order to enable the locking assembly 20 to maintain a state of limited engagement with the stylus body 60 under normal conditions, thereby allowing the pen tip structure to maintain a stable connection with the stylus body 60 in actual application scenarios and preventing the locking assembly 20 and the pen body 60 from loosening for no reason during use by the user, please refer to Figures 4 to 7. The pen tip structure also includes an energy storage component 40. The energy storage component 40 is configured to be compressed or stretched under the action of an external force and to generate a reaction force in the opposite direction of the action force, and to maintain the stability of the structural form under the action of no external force.

[0045] Specifically, the energy storage component 40 can be located inside (i.e., within the mounting cavity 121) or outside the pen tip 10, depending on the structural design requirements of the pen tip structure. When the pen tip structure is assembled and used, the energy storage component 40 can remain in a stretched or compressed energy storage state, thereby continuously applying an elastic force in the opposite direction of stretching or compressing to the relevant components. It is understood that in order to keep the locking assembly 20 in a normal state (which can be understood as a state without other external forces, such as external forces applied by user operation), one end of the energy storage component 40 acts on the pen tip 10, and the other end of the energy storage component 40 acts on the locking assembly 20 and / or the trigger assembly 30. Here, the energy storage component 40 can continuously apply a force to the locking assembly 20 to move in the direction of the locked position, so that the locking assembly 20 has a tendency to move in the direction of the locked position.

[0046] To facilitate understanding of the solution, the locking assembly 20 of this embodiment includes a locking position and an unlocking position. According to the description of the above embodiment, when the locking assembly 20 is in the locking position, the locking assembly 20 can form a limited matching relationship with the pen body 60 of the stylus pen, that is, when the locking assembly 20 is in the locked position, the pen tip structure can be installed on the pen body 60, and when the locking assembly 20 is in the unlocking position, the locking assembly 20 releases the mutual constraint with the pen body 60, so that the pen tip structure can be removed from the pen body 60.

[0047] In an embodiment where the trigger assembly 30 can only drive the locking assembly 20 to move from the locked position to the unlocked position, an elastic component can also be provided between the locking assembly 20 and the pen tip 10 so that the locking assembly 20 can be reset from the unlocked position to the locked position through the elastic component when the trigger assembly 30 loses its function.

[0048] According to the above description of the energy storage component 40, the energy storage component 40 can apply elastic force to the locking assembly 20 to move toward the locking position in the following ways:

[0049] 1. As shown in Figures 4 to 7 , the energy storage component 40 acts on the pen tip contact member and the trigger assembly 30 respectively. By applying a force to the trigger assembly 30, the locking assembly 20 is in the unlocked position. When the user does not operate the trigger assembly 30, the trigger assembly 30 can drive the locking assembly 20 to move from the unlocked position to the locked position and finally reset and stabilize in the locked position.

[0050] Second, the energy storage component 40 acts on the pen tip contact piece and the locking assembly 20 respectively. By applying a force directly to the locking assembly 20, when the locking assembly 20 is in the unlocked position and the user does not operate the trigger assembly 30, the locking assembly 20 can move from the unlocked position to the locked position under the direct action of the energy storage component 40 and finally stabilize in the locked position. During this process, the locked position can also drive the trigger assembly 30 to reset simultaneously so that the user can operate it again;

[0051] 3. One end of the energy storage component 40 acts on the pen tip contact piece, and the other end thereof acts on the locking assembly 20 and the trigger assembly 30 at the same time, so that when the locking assembly 20 is in the locked position and the user does not operate the trigger assembly 30, the energy storage component 40 can simultaneously apply a resetting force to the locking assembly 20 and the trigger assembly 30.

[0052] It should be understood that in both the first and second coupling modes, in addition to being able to move the locking assembly 20 from the locked position to the unlocked position under the action of the trigger assembly 30, the locking assembly 20 can also be linked to the trigger assembly 30 under the action of the energy storage component 40. That is, when a force is applied to the locking assembly 20 to move it from the unlocked position to the locked position, or when a force is applied to the locking assembly 20 to move it from the locked position to the unlocked position, the trigger assembly 30 can be linked to the locking assembly 20, moving synchronously with the locking assembly 20. For example, if the trigger assembly 30 is a button, the user can press the button to cause the locking assembly 20 to change position, and the locking assembly 20 can also reset the button under the action of the energy storage component 40. In this way, the energy storage component 40 can apply force to only one of the locking assembly 20 or the trigger assembly 30, thereby reducing the installation space occupied by the energy storage component 40, simplifying the assembly structure, effectively improving the compactness of the pen tip structure, and reducing the difficulty of assembly between components.

[0053] In one embodiment, a component or structure capable of constraining and increasing friction can be provided between the locking assembly 20 and the trigger assembly 30 to stabilize the locking assembly 20 in the corresponding position. For example, a snap-fit ​​structure capable of constraining the locking assembly 20 can be provided at the portion of the pen tip 10 where the locking assembly 20 is in the locked and unlocked positions, or a wedge-tightening structure or damping sleeve can be provided at the corresponding positions. This constrains the locking assembly 20 in the corresponding position or increases the friction between the locking assembly 20 and the pen tip 10, thereby allowing the locking assembly 20 to remain stable in the corresponding position within a certain range of applied force, thereby reducing the user's operational difficulty.

[0054] It is also necessary to give an example to illustrate that the energy storage component 40 of this embodiment can adopt a compression spring or a tension spring. In the embodiment where the energy storage component 40 is a compression spring, the compression spring can be arranged in the installation cavity 121 and act on the cavity wall of the installation cavity 121 (equivalent to the pen tip 10) and the locking assembly 20 and / or the trigger assembly 30 to achieve the effect of continuously applying force to the locking assembly 20; and in the embodiment where the energy storage component 40 is a tension spring, the tension spring can be arranged on the outside of the pen tip 10, and act on the outer wall of the pen tip 10 and the locking assembly 20 and / or the trigger assembly 30 to achieve the effect of continuously applying force to the locking assembly 20.

[0055] Of course, the energy storage component 40 may also be made of other elastomeric materials with elastic reset capabilities, such as rubber, sponge, foam, etc.

[0056] Please continue to refer to Figures 4, 6 and 7, and continue to take the embodiment in which the pen tip structure includes an energy storage component 40 as an example. On the basis of the above embodiment, a spring piece 41 is arranged between the energy storage component 40 and the pen tip 10. Like the energy storage component 40, the spring piece 41 has the ability to produce elastic deformation under the action of external force and elastically restore when the external force is lost. It can be made of a material with a certain rigidity and elasticity (such as plastic, metal), so that it can support the energy storage component 40 while also applying a certain elastic force to the energy storage component 40.

[0057] In this embodiment, the energy storage component 40 can be connected to the pen tip 10 through the spring clip 41, that is, one end of the energy storage component 40 acts on the locking assembly 20 and / or the trigger assembly 30, and the other end of the energy storage component 40 acts on the second end of the spring clip 41. The force generated by one end of the energy storage component 40 needs to be transmitted to the pen tip 10 through the spring clip 41. Specifically, the first end of the spring clip 41 is fixedly connected to the pen tip 10, and a deformation gap 411 is formed between the second end of the spring clip 41 and the pen tip 10. Taking the embodiment in which a compression spring is used as the energy storage component 40 as an example, the deformation gap 411 is located on the side of the spring piece 41 away from the compression spring. In this way, when the compression spring is compressed toward the spring piece 41 under the action of the trigger assembly 30, the spring piece 41 can also deform relative to the pen tip 10 toward the side where the deformation gap 411 is formed and store energy. When the trigger assembly 30 loses the external force, the locking assembly 20 and / or the trigger assembly 30 can not only be reset under the action of the compression spring, but the spring piece 41 also releases the energy stored in the deformation together with the compression spring, and transfers the energy to the compression spring, thereby enhancing the force applied by the compression spring on the locking assembly 20 and the trigger assembly 30. Moreover, through such a setting, the spring piece 41 cooperates with the compression spring to enhance the force acting on the trigger assembly 30 and / or the locking assembly 20, thereby making the locking assembly 20 more stable in the locked position and improving the assembly strength of the pen tip structure and the pen body 60.

[0058] According to the above embodiment, it can be known that by providing the spring clip 41, the force applied by the energy storage component 40 to the trigger component 30 and / or the locking component 20 can be enhanced, so that the locking component 20 is more stable in the locked position state. The method of enhancing the resetting force of the locking component 20 by the spring clip 41 can also reduce the force requirements brought by the energy storage component 40 to a certain extent. For example, in the embodiment of using a tension spring or a compression spring as the energy storage component 40, the size requirements for the tension spring or the compression spring can be relatively reduced, thereby reducing the installation space occupied by the energy storage component 40, which is conducive to its application in products with small and narrow installation spaces such as styluses / smart pens.

[0059] Continuing with the above embodiment, taking the embodiment of using a tension spring as the energy storage component 40 as an example, the spring 41 can also enhance the tension applied by the tension spring on the trigger assembly 30 and / or the locking assembly 20 by forming a deformable gap 411 between the spring and the pen tip 10.

[0060] In the embodiment where the pen tip contact is provided with a spring piece 41 , the spring piece 41 can also be used as a component connected to the negative electrode of the battery 80 of the stylus pen / smart pen through its connection with the pen tip contact.

[0061] Please refer to Figures 3, 6-9. As an embodiment that is independent of the above-mentioned scheme of providing the energy storage component 40 and the spring 41, as one specific embodiment of the locking assembly 20, the locking assembly 20 includes a first locking portion 211 and a second locking portion 212 arranged opposite to each other. The first locking portion 211 and the second locking portion 212 are respectively engaged with the trigger assembly 30. The first locking portion 211 and the second locking portion 212 can generate relative movement with the trigger assembly 30 and the pen tip transmission member. By changing the relative positions of the first locking portion 211 and the second locking portion 212 and the pen tip transmission member, the first locking portion 211 and the second locking portion 212 can be limitedly engaged with the pen body 60 of the stylus pen at a preset position or disengaged from the pen body 60.

[0062] In one embodiment, according to the aforementioned embodiment in which the locking assembly 20 can be expanded and retracted relative to the mounting opening 122, specifically, under the action of the trigger assembly 30, the first locking portion 211 and the second locking portion 212 can move relative to each other between a retracted position in which they are close to each other and an extended position in which they are separated from each other. The first locking portion 211 and the second locking portion 212 can form a restraining engagement with the stylus body 60 in the retracted position, and correspondingly, can disengage from the stylus body 60 in the extended position. Conversely, the first locking portion 211 and the second locking portion 212 can also form a restraining engagement with the stylus body 60 in the extended position, and correspondingly, disengage from the stylus body 60 in the retracted position.

[0063] In another embodiment, according to the aforementioned embodiment in which the locking assembly 20 can be extended or retracted relative to the mounting opening 122, under the action of the trigger assembly 30, the first locking portion 211 and the second locking portion 212 can be configured to perform telescopic movement relative to the pen tip 10 through the mounting opening 122. That is, the first locking portion 211 and the second locking portion 212 can be configured to simultaneously extend from the mounting cavity 121 toward the mounting opening 122, and to simultaneously retract from the mounting opening 122 toward the mounting cavity 121. Similarly, in this embodiment, the first locking portion 211 and the second locking portion 212 can be configured to engage with the pen body 60 in the extended state and disengage from the pen body 60 in the retracted state, depending on the specific design of the pen tip structure. Alternatively, the first locking portion 211 and the second locking portion 212 can be configured to disengage from the pen body 60 in the extended state and engage with the pen body 60 in the extended state, or to engage with the pen body 60 in the extended state and disengage from the pen body 60 in the extended state.

[0064] In the above-mentioned embodiment in which the first locking portion 211 and the second locking portion 212 can perform telescopic movement, it can be understood that when the first locking portion 211 and the second locking portion 212 are in the retracted position, the first locking portion 211 and the second locking portion 212 can be completely retracted into the installation cavity 121, or at least partially remain outside the installation cavity 121. Correspondingly, when the first locking portion 211 and the second locking portion 212 are in the retracted position, the first locking portion 211 and the second locking portion 212 are completely placed in the installation cavity 121, and the extended position of the first locking portion 211 and the second locking portion 212 can also be set to a state in which they are completely placed in the installation cavity 121. In other words, in the extended position, the distance between the first locking portion 211, the second locking portion 212 and the installation opening 122 is smaller than the distance when in the retracted position.

[0065] It should be understood that in other embodiments, the locking assembly 20 can also be assembled and disassembled with the pen body 60 of the stylus pen only through a locking portion that can be relative to the pen tip 10, or the locking assembly 20 can also include a third, fourth, etc. locking portion in addition to the first locking portion 211 and the second locking portion 212..., so as to achieve assembly and disassembly with the pen body 60 by cooperating with two or more locking portions.

[0066] Below, taking the implementation method of the relative movement between the foldable and unfolded positions of the first locking portion 211 and the second locking portion 212 as an example, please continue to refer to Figures 3, 6-9. As an optional implementation method of the above scheme, the locking assembly 20 includes two movable parts 21 that are cross-arranged and rotatably connected at the intersection, and the rotation center of the two movable parts 21 is located between the first end and the second end of the two movable parts 21 and is arranged to overlap. Specifically, the first end of one of the movable members 21 forms the above-mentioned first locking portion 211, and the first end of the other movable member 21 forms the above-mentioned second locking portion 212. The trigger assembly 30 can act on the second ends of the two movable members 21. For example, the trigger assembly 30 can be at least partially arranged between the second ends of the two movable members 21. In this way, the trigger assembly 30 drives the second ends of the two movable members 21 to move in the direction of approaching each other and away from each other, so that the first locking portion 211 and the second locking portion 212 rotate synchronously around the rotation center. The first locking portion 211 and the second locking portion 212, which are respectively the first ends of the two movable members 21, move in the direction of approaching or away from each other under the drive of the second end of the movable member 21, thereby implementing assembly and disassembly with the pen body 60.

[0067] The first locking portion 211 and the second locking portion 212 are secured by two intersecting movable members 21, which rotate about the same axis of rotation, thereby improving the stability of the relative motion between the first locking portion 211 and the second locking portion 212. Furthermore, the intersecting movable members 21 rotate in a relatively small amount of space, thereby contributing to the compact design of the locking assembly 20.

[0068] In the above embodiment, the second end of the movable member 21 rotates around its rotation axis under the action of the trigger assembly 30, and the first end and the second end thereof can also use the lever principle to enable the first locking portion 211 and the second locking portion 212 as the first end to apply a greater force to the contrast tube, thereby achieving the effect of improving the assembly strength of the locking component and the pen body 60.

[0069] This embodiment also provides another technical solution that is independent of the cross-setting of the two movable parts 21 mentioned above. In this solution, taking the two movable parts 21 as an example, the two movable parts 21 can be set as two parts that are parallel to each other or nearly parallel to each other and are spaced apart. The trigger assembly 30 can be set between the two movable parts 21, so that the two movable parts 21 can be driven to move closer to or farther away from each other by horizontal movement, etc., so as to achieve the purpose of moving the first locking part 211 and the second locking part 212 to the expanded position or the folded position.

[0070] Of course, in the embodiment where the first locking portion 211 and the second locking portion 212 can move in the telescopic direction, the extension or retraction of the two relative to the installation opening 122 can also be implemented by two movable members 21 arranged parallel to each other, or movable members 21 arranged crosswise to each other.

[0071] Please continue to refer to Figures 3, 6-9, and continue with the above-mentioned implementation method in which the two movable parts 21 are cross-arranged and rotated together. The two movable parts 21 are rotatably connected to the pen tip 10 through the rotating shaft 22. The rotating shaft 22 defines the rotation axis of the movable parts 21, so that the two movable parts 21 can be connected and fixed by the same rotating shaft 22, meeting the compact design requirements of the locking assembly 20. In this example, in order for the movable part 21 to achieve relative rotation with the pen tip 10, the movable part 21 needs to use the rotating shaft 22 as a fulcrum and form a physical connection relationship with the pen tip 10 that can transmit interactive force. To this end, on the basis of providing the rotating shaft 22, the pen tip 10 is provided with a first axial hole 13 that is connected to the mounting cavity 121. Correspondingly, the rotation centers of the two movable parts 21 are penetrated by a second axial hole 213 that matches the rotation center. The rotating shaft 22 penetrates into the mounting cavity 121 through the first axial hole 13 and is connected to the second axial hole 213. A matching limiting structure can be designed between the rotating shaft 22 and the pen tip 10 to limit the axial movement of the rotating shaft 22, so that the rotating shaft 22 can be stably set in the mounting cavity 121, thereby improving the installation accuracy between the two movable parts 21 and the pen tip 10, and the relative movement stability between the two movable parts 21.

[0072] In one embodiment, in order to allow the rotating shaft 22 to be fixedly mounted on the pen tip 10 , the portion of the rotating shaft 22 that passes through the first shaft hole 13 may be provided with an external thread structure, and correspondingly, the first shaft hole 13 is provided with a matching internal thread structure. Optionally, a screw head 221 may be provided at one end of the rotating shaft 22, with a groove formed on the screw head 221 adapted to fit an assembly tool (such as a screwdriver, hexagonal key, etc.). On one side of the screw head 221, the outer surface of the rotating shaft 22 may be machined with the aforementioned external thread structure. Correspondingly, a recessed groove 131 may be provided around the periphery of the first axial hole 13 of the pen tip 10 for accommodating the screw head 221. After the rotating shaft 22 forms a rotational fit with the two movable members 21 through the first axial hole 13 and the second axial hole 213, the external thread structure thereof may be threadedly engaged with the internal thread structure of the pen tip 10. Finally, the screw head 221 is accommodated in the recessed groove 131, thereby improving the compactness of the pen tip structure and limiting the degrees of freedom of the rotating shaft 22 in all directions (axial, radial, and circumferential). The second axial hole 213 may be configured to be clearance-fitted with the rotating shaft 22, thereby enabling relative rotation between the movable member 21 and the rotating shaft 22.

[0073] On the basis of the above embodiment, in order to improve the matching stability between the rotating shaft 22 and the pen tip 10, two opposite first axial holes 13 are provided on the opposite sides of the pen tip 10, and the above-mentioned internal thread structure needs to be provided in at least one first axial hole 13, so that the rotating shaft 22 passes through the mounting cavity 121 from one of the first rotating shafts 22, and then passes through the second axial hole 213 from the movable part 21, and can match with the other first axial hole 13, so that the opposite ends of the rotating shaft 22 can be constrained and restricted by the pen tip 10.

[0074] Please refer to Figures 4 to 7. In the embodiment in which the locking assembly 20 includes two movable parts 21, combined with the embodiment in which the pen tip structure also includes an energy storage component 40, in addition to being able to act on the trigger assembly 30 and / or the two movable parts 21, the energy storage component 40 can also be disposed between the pen tip 10 and the trigger assembly 30, so that the energy storage component 40 acts on the end of the trigger assembly 30 that is away from the end exposed to the pen tip 10, so as to continuously apply a force to the first locking portion 211 and the second locking portion 212 to move toward the locking position through the trigger assembly 30.

[0075] In the embodiment where the energy storage components 40 act separately on the two movable members 21, the energy storage components 40 can be configured as compression springs or tension springs, with the same number as the movable members 21. By disposing a corresponding energy storage component 40 between each movable member 21 and the pen tip 10, the elastic force that causes the movable member 21 to move toward the locked position is provided. Of course, the arrangement between the energy storage component 40 and the movable member 21, as well as between the triggering assembly, is not limited to the above embodiment. The above embodiment is merely an illustrative example to provide a more comprehensive and clear understanding of the technical means of this solution.

[0076] In the following, the manner in which the locking assembly 20 can be assembled and matched with the pen body 60 of the smart pen when the first locking portion 211 and the second locking portion 212 are in the extended position away from each other is taken as an example.

[0077] According to the above description of the cooperation between the locking assembly 20 and the pen body 60, under the above constraints, the first locking portion 211 and the second locking portion 212 are respectively provided with hooks 23 for snapping together with the pen body 60 of the smart pen. The two hooks 23 are extended in directions away from each other, and the hooks 23 are configured to form a snap-fit ​​relationship with the pen body 60 of the stylus. Specifically, in the application of the stylus pen / smart pen, a card slot that is compatible with the card hook 23 is provided on the inner tube wall of the pen body 60. During the assembly process of the pen head structure and the pen body 60, the user can operate the trigger assembly 30 to cause the trigger assembly 30 to drive the two movable parts 21 to rotate around the rotating shaft 22 in the direction of approaching each other. When the first locking part 211 and the second locking part 212 move to the retracted position close to each other along with the movable part 21, the distance between the first locking part 211 and the second locking part 212 is smaller than the distance between the two relative card slots in the relative position, so that the end of the pen head assembly with the installation opening 122 can be inserted into the pen body 60. When the pen head assembly is inserted into the pen body 60 and the first locking part 212 is engaged, the first locking part 211 and the second locking part 212 are engaged. When the stop portion 211 and the second locking portion 212 are respectively in a relative position with the two opposite slots, the user can release the trigger assembly 30 so that the energy storage component 40 can drive the trigger assembly 30 and / or the locking assembly 20 to move during the elastic reset process. Finally, the first locking portion 211 and the second locking portion 212 move away from each other under the drive of the two movable parts 21 and are finally respectively stuck in the two opposite slots and reach the expanded position. The two slots can limit and constrain the movement of the first locking portion 211 and the second locking portion along the length direction of the pen body 60, thereby constraining the entire pen tip structure to the pen body 60, and completing the assembly of the pen tip structure and the pen body 60.

[0078] On the contrary, when the pen tip structure needs to be removed from the pen body 60, the user can re-operate the trigger assembly 30 to retract the first locking portion 211 and the second locking portion 212 and disengage them from the slot, allowing the pen tip structure to be pulled out of the pen body 60, thereby completing the disassembly of the pen tip assembly.

[0079] Referring to Figures 3, 6-9, and continuing with the example of a locking assembly 20 comprising a first locking portion 211 and a second locking portion 212 disposed opposite each other, a grounding assembly 50 is disposed between the first locking portion 211 and the second locking portion 212. The grounding assembly 50 is mounted and engaged with the first locking portion 211 and the second locking portion 212. In this embodiment, the grounding assembly 50 is disposed in the space between the first locking portion 211 and the second locking portion 212. The grounding assembly 50 is at least partially exposed to the exterior of the pen tip 10 through the mounting opening 122 between the first locking portion 211 and the second locking portion 212. In the application of the stylus / smart pen, the grounding component 50 can be used to electrically connect to the negative pole of the battery 80 set in the pen body 60. In this way, the grounding component 50 can be connected to the pen tip 10 for grounding through the locking component 20. Moreover, when the circuit board 90 set in the pen body 60 is also grounded with the pen body 60, the pen tip 10 is connected to the pen body 60, so that the pen tip structure, pen body 60, battery 80, and circuit board 90 form a loop, thereby supplying power to the circuit board 90.

[0080] Continuing with Figures 3-4, 6-7, and 11, to ensure that the pen tip structure forms a stable face-to-face connection with the negative terminal of the battery 80 located within the stylus / smart pen body 60 when assembled, the grounding assembly 50 includes a grounding elastic member 51 and a grounding spring 52. The grounding elastic member 51 ensures that the grounding assembly 50 is relatively stably positioned between the first locking portion 211 and the second locking portion 212, ensuring a stable connection between the grounding assembly 50 and the locking assembly 20. Furthermore, through the assembly between the locking assembly 20 and the pen tip 10, and the engagement between the pen tip 10 and the pen body 60, a conductive connection is established between the grounding assembly 50 and the pen body 60. The grounding spring 52 ensures that the grounding assembly 50 forms a stable electrical connection with the negative terminal of the battery 80 located within the pen body 60 when the pen tip assembly and the pen body 60 are assembled.

[0081] As for the specific structural form of the above-mentioned grounding component 50, the grounding elastic member 51 includes a first end and a second end that are spaced apart and relatively arranged, and the first end and the second end are connected to form a grounding portion 511 at the connection point. It should be understood that the structure of the grounding elastic member 51 of this embodiment is an adaptive design made when the locking component 20 includes a first locking portion 211 and a second locking portion 212. When the above-mentioned locking component 20 is only equipped with one locking portion, or is equipped with more than two locking portions, the number of ends of the grounding elastic member can also be adaptively adjusted according to the number of locking portions. Please continue to refer to Figures 3-4, 6-7, and 11, and return to the embodiment in which the grounding elastic member 51 has a first end and a second end relative to each other. In this scheme, the first end of the grounding elastic member 51 is installed and cooperated with the first locking portion 211, and the second end of the grounding elastic member 51 is installed on the second locking portion 212. The grounding portion 511 formed at the first and second ends of the grounding elastic member 51 passes through the space between the first locking portion 211 and the second locking portion 212, and is exposed from the pen tip contact member through the installation port 122.

[0082] In order to ensure a good and stable assembly relationship between the grounding elastic member 51 and the locking assembly 20, in one embodiment, the first end and the second end of the grounding elastic member 51 can be respectively provided with a limiting structure for cooperating with the first locking portion 211 and the second locking portion 212. For example, as shown in Figures 6 to 9, a hook 512 and / or a limiting protrusion 513 can be respectively provided on the side opposite to the first end and the second end of the grounding elastic member 51, and a hook groove 216 and / or a limiting hole 217 that can adapt to the hook 512 and the limiting protrusion 513 can be provided on the side opposite to the first locking portion 211 and the second locking portion 212. It can be understood that the grounding elastic member 51 has the characteristic that the first end and the second end can be elastically deformed in the direction of approaching and moving away from each other. During the assembly of the locking portion 212, the first end and the second end of the grounding elastic member 51 can be compressed in a direction toward each other, so that the distance between the first end and the second end is smaller than the distance between the first locking portion 211 and the second locking portion 212. In this way, the first end and the second end of the grounding elastic member 51 can be placed between the first locking portion 211 and the second locking portion 212, and the above-mentioned limiting structure forms a positional matching relationship. Subsequently, the grounding elastic member 51 is released, so that the first end and the second end thereof can be limited and matched with the first locking portion 211 and the second locking portion 212 through the limiting structure after being unfolded.

[0083] In one embodiment, when the grounding elastic member 51 is installed and matched with the locking assembly 20, the first end and the second end of the grounding elastic member 51 can remain in a state of being compressed in a direction toward each other, so that the grounding elastic member 51 continues to apply pressure to the first locking portion 211 and the second locking portion 212, so that any two matching components can maintain a good matching relationship through the above-mentioned limiting structure.

[0084] Continuing with the aforementioned embodiment in which the grounding elastic member 51 maintains an elastic force on the locking assembly 20, in embodiments where the first locking portion 211 and the second locking portion 212 can move between positions approaching and separating from each other, and where the first locking portion 211 and the second locking portion 212 are in the deployed position and can be mounted on the pen body 60, the grounding elastic member 51 can further exert a force on each of the first locking portion 211 and the second locking portion 212 to move toward the deployed position. This allows the locking assembly 20 to more stably maintain the deployed position when in a positionally limited engagement with the pen body 60, thereby improving the locking stability of both. Furthermore, in embodiments where the locking assembly 20 includes two movable members 21, the first and second ends of the movable members 21 can rely on the energy storage component 40 and the grounding elastic member 51, respectively, to ensure that the entire movable member 21 has a tendency to move in the deployed direction. This reduces the burden on the energy storage component 40 to a certain extent, while also ensuring a more reliable engagement of the movable member 21 with the pen body 60 in the deployed position.

[0085] Continuing with the above embodiment, the grounding spring 52 is arranged on the grounding portion 511, and the grounding spring 52 is extended in a direction away from the mounting cavity 121. When the pen tip structure and the pen body 60 are installed and matched, the grounding spring 52 is compressed and pressed between the grounding elastic member 51 and the negative pole of the battery 80 to ensure the connection between the grounding elastic member 51 and the battery 80.

[0086] Please refer to Figures 3 and 5 to 9, and take the solution in which the above-mentioned locking component includes two movable parts 21 as an example. In this embodiment, a first guide portion 214 is respectively provided on the opposite side of the two movable parts 21, and a second guide portion 321 is respectively provided on the opposite sides of the two first guide portions 214 of the trigger assembly 30. The two second guide portions 321 are respectively guided and cooperated with the two first guide portions 214, and the first guide portion 214 and the second guide portion 321 can achieve relatively smooth movement during the interaction. That is, when the user operates the trigger assembly 30, the trigger assembly 30 acts on the first guide portion 214 of the two movable parts 21 through the second guide portion 321, so that stable relative movement can be achieved between the first guide portion 214 and the second guide portion 321, so that the two movable parts 21 can move relative to the trigger assembly 30 respectively.

[0087] Following the above solution, in combination with the solution in which the two movable members 21 are cross-arranged and can move relative to each other around the same rotation axis, in order to enable the first locking portion 211 and the second locking portion 212 to stably move between the folded position and the extended position, the following exemplary specific cooperation methods of the first guide portion 214 and the second guide portion 321 are provided:

[0088] 1. The distance between the two first guide portions 214 gradually increases from the first side to the second side of the movable member 21;

[0089] 2. The distance between the two second guide portions 321 gradually increases from the first side to the second side of the trigger assembly 30;

[0090] 3. The distance between the two first guide portions 214 gradually increases from the first side to the second side of the movable member 21 , and the distance between the two second guide portions 321 gradually increases from the first side to the second side of the trigger assembly 30 .

[0091] For example, the first side mentioned above can be understood as the side of the pen tip structure shown in Figure 4 where the components are close to the trigger assembly 30 and exposed by the pen tip 10 (i.e., the upper side in the figure), and the second side can be understood as the side of the pen tip structure where the components are away from the trigger assembly 30 and exposed by the pen tip 10 (i.e., the lower side in the figure).

[0092] According to the above-mentioned setting method, the first limiting part 215 and the second limiting part 322 include three different structural forms, namely, the distance between the two first limiting parts 215 on the first side is smaller than the distance between the two second limiting parts 322 on the first side, the distance between the two second limiting parts 322 on the first side is smaller than the distance between the two second limiting parts 322 on the second side, and the distance between the two first limiting parts 215 and the two second limiting parts 322 on the first side is smaller than the distance on the second side. In the above-mentioned matching method three, the first limiting part 215 and the relative second limiting part 322 can be configured as a matching structure to improve the stability during the relative movement of the two, while also effectively reducing the friction between the two and reducing the wear generated during the relative movement.

[0093] For example, in the above embodiment, taking the solution in which the locking assembly 20 can be disengaged from the pen body 60 of the stylus when in the retracted position and can be installed and engaged with the pen body 60 when in the extended position as an example, when the trigger assembly 30 is located on the first side of the two movable parts 21, due to the narrow distance between the two first guide portions 214 and / or the two second guide portions 321, the two movable parts 21 can be in the extended position where they are extended with each other under the action of the energy storage component 40 or driven by the trigger assembly 30. As the trigger assembly 30 moves from the first side to the second side of the movable part 21, the distance between the two first guide portions 214 and / or the two second guide portions 321 gradually expands, thereby allowing the two movable parts 21 to gradually move toward the retracted position where they are close to each other.

[0094] Of course, the above arrangement is merely an example of how the first locking portion 211 and the second locking portion 212 can be driven to smoothly move between different positions. Alternatively, the first guide portion 214 and / or the second guide portion 321 can be configured to gradually expand from the second side to the first side. Furthermore, the relative movement of the trigger assembly 30 and the movable member 21 is not necessarily limited to the embodiment described above where the trigger assembly 30 is positioned between the first and second sides of the movable member. The trigger assembly 30 can also be positioned between the first side of the movable member 21 and a position away from the second side thereof, or between the second side of the movable member 21 and a position away from the first side thereof.

[0095] By gradually widening and narrowing the distance between the two first guide portions 214 and / or the two second guide portions 321 , the trigger assembly 30 and the movable member 21 can smoothly move relative to each other during the relative movement.

[0096] It should be understood that the above-mentioned solution for achieving the relative movement of the two movable members 21 between the folded position close to each other and the extended position away from each other can also be used in an embodiment in which the two movable members 21 are spaced apart and arranged horizontally.

[0097] In one embodiment, the direction in which the trigger assembly 30 moves relative to the pen tip 10 is parallel to the rotation axis of the movable member 21. Referring to the above-described embodiment, in this embodiment, the trigger assembly 30 can be disposed on the first or second side of the movable member 21 and reciprocate along the direction from the first side to the second side, and from the second side to the first side, of the movable member 21, thereby enabling the first and second ends of the movable member 21 to move about their rotation axis between a retracted position and an extended position. This solution converts linear motion into rotational motion, and by at least partially staggering the trigger assembly 30 and the locking assembly 20 between the first and second ends of the pen tip 10, space is saved along the length of the mounting cavity 121. This provides sufficient mounting space for the nib 70 while also saving corresponding mounting space for other components. Furthermore, the trigger assembly 30 is arranged on the side of the locking assembly 20 rather than being arranged along the length direction of the pen tip 10 together with the locking assembly 20. This can also facilitate at least part of the trigger assembly 30 to be exposed on the side of the pen tip 10, and will not interfere with other components such as the pen tip 70, which is suitable for the compact design of the pen tip structure.

[0098] Of course, in other embodiments, the pen tip structure of this embodiment does not exclude the possibility that the direction of movement of the trigger assembly 30 relative to the pen tip 10 can also be set to be perpendicular to the rotation axis of the movable part 21. In this solution, the trigger assembly 30 and the locking assembly 20 can be set between the first end and the second end of the pen tip 10 along the length direction of the pen tip 10.

[0099] In the above-mentioned embodiment in which the two movable parts 21 are arranged with differential rotation, the transmission cooperation between the trigger assembly 30 and the locking assembly 20 is a method of converting linear motion into rotational motion, which is more stable and has higher transmission efficiency than the above-mentioned parallel arrangement, and also saves more space in the installation cavity 121.

[0100] In the above embodiment, in order to allow the trigger assembly 30 to stably drive the locking assembly 20 to move relative to the pen tip 10 during the movement relative to the pen tip contact member, and in some embodiments, in order to allow the locking assembly 20 to drive the trigger assembly 30 to move relative to the pen tip 10 during the movement relative to the pen tip 10. As shown in Figures 3 and 5 to 9, this embodiment is further provided with a first limiting portion 215 on the first guide portion 214, and correspondingly, the second guide portion 321 is provided with a second limiting portion 322 adapted to the first limiting portion 215. The first limiting portion 215 and the second limiting portion 322 are limitedly matched to limit the first limiting portion 215 and the second limiting portion 322 from moving away from each other. In this way, no matter what relative position matching method is adopted between the trigger assembly 30 and the locking assembly 20, and the trigger assembly 30 Regardless of the relative movement direction between the locking assembly 20, during the linkage between the trigger assembly 30 and the locking assembly 20, the first guide portion 214 and the second guide portion 321 can maintain a coordinated state under the limiting cooperation relationship between the first limiting portion 215 and the second limiting portion 322, so that the locking assembly 20 can move relative to the pen tip 10 at the same time as the trigger assembly 30 under the action of the trigger assembly 30, and can also move relative to the pen tip 10 at the same time as the trigger assembly 30 under the action of the locking assembly 20.

[0101] According to the technical solution described above, in an embodiment where the pen tip structure further includes an energy storage component 40, when a user operates the trigger assembly 30, the trigger assembly 30 moves relative to the pen tip 10. Under the action of the first stopper 215 and the second stopper 322, the first guide portion 214 drives the second guide portion 321, causing the locking assembly 20 to engage with the trigger assembly 30, thereby enabling the locking assembly 20 to switch from a positional engagement with the pen body 60 to a position separated from the pen body 60. When the user releases the trigger assembly 30, removing the external force acting on the trigger assembly 30 and the locking assembly 20, the energy storage component 40 pushes the locking assembly 20 to reset. At this point, the locking assembly 20 resets relative to the pen tip 10. Under the action of the second stopper 322 and the first stopper 215, the second guide portion 321 drives the first guide portion 214, causing the trigger assembly 30 to synchronously reset to a position where it can be triggered by the user.

[0102] In one embodiment, as shown in Figures 3 and 5 to 9, a first guide surface is formed on the first guide portion 214, and a second guide surface for pushing the first guide portion 214 is correspondingly formed on the second guide portion 321. The first guide surface and the second guide surface are parallel to each other and form surface contact, thereby improving the stability of the first guide portion 214 and the second guide portion 321 in the mating state.

[0103] In combination with the above description of the spacing between the two first limiting portions 215 and the spacing between the two second limiting portions 322, this embodiment takes the above-mentioned cooperation method three as an exemplary illustration, that is, the spacing between the two first guide portions 214 gradually increases from the first side of the movable part 21 to the second side, and the spacing between the two second guide portions 321 gradually increases from the first side to the second side of the trigger assembly 30. To achieve this purpose, the two opposing first guide surfaces, and the two opposite and two second guide surfaces are all relatively inclined in a cross-sectional shape that is approximately "eight" shaped, so that the spacing between the two first guide surfaces and the two second guide surfaces can gradually increase from the first side to the second side.

[0104] Continuing with the above embodiment, the first limiting portion 215 can be provided at one end or two opposite ends of the first guide surface along the length direction of the pen tip 10, and the corresponding second limiting portion 322 corresponds to the position of the first limiting portion 215 and can also be provided at the first end or two opposite ends of the second guide surface along the length direction of the pen tip 10 to form a limiting cooperation relationship with the first guide portion 214. In one embodiment, as shown in Figures 3 and 5 to 9, the first limiting portion 215 is a limiting groove provided at the second end of the movable block and located at two opposite ends of the first guide surface, and the corresponding second limiting portion 322 is a limiting block protruding from the trigger assembly 30 and located at two opposite ends of the second guide surface. The limiting block can be accommodated in the limiting groove to limit the movement of the first guide surface and the second guide surface in a direction of relative separation, and can allow the transmission of the locking assembly 20 and the trigger assembly 30 during the movement between the locked position and the unlocked position.

[0105] Please refer to Figures 4 to 9. As a solution that can be combined with any of the above-mentioned embodiments, the trigger assembly 30 of this embodiment specifically includes a button body 31 and a guide block 32. The trigger assembly 30 is designed as two separate and transmission-coordinated components, which can facilitate assembly and disassembly in installation locations such as pen tip structures and products with relatively narrow spaces, thereby reducing the difficulty of product structure design and disassembly.

[0106] Specifically, the button body 31 can be movably arranged on one side of the pen tip 10. The button body 31 serves as a component that provides the user with an operating position for operating the trigger assembly 30. The button body 31 is at least partially exposed from the side of the pen tip 10, and the part exposed on the side of the pen tip 10 forms an operable operating part 311. The user can operate the button body 31 through the operating part 311. It should be noted that the operation mode of the button body 31 can be determined according to the transmission mode of the trigger assembly 30 and the locking assembly 20, as well as the direction of the force of the energy storage component 40 when the energy storage component 40 is provided. Generally speaking, the operation direction of the button body 31 is opposite to the direction of the force provided by the energy storage component 40. In this way, the button body 31 can enable the trigger assembly 30 to drive the locking assembly 20 to move from the locked position to the unlocked position, and the energy storage component 40 can drive the locking component to reset from the unlocked position to the locked position. The guide block 32 is a component that actually has a transmission relationship with the locking assembly 20. Its entirety is movably arranged in the mounting cavity 121. In addition, the guide block 32 is respectively coordinated with the button body 31 and the locking assembly 20 so that the guide block 32 can drive the locking assembly 20 to move under the action of the button body 31. When the user operates the button body 31 through the operating part 311, the button body 31 can drive the guide block 32 to move synchronously with the button body 31, and the guide block 32 has a transmission relationship with the locking assembly 20 to drive the locking assembly 20 to change its position state.

[0107] Continuing with the above embodiment, combined with the scheme in which the trigger assembly 30 is provided with two opposite second guide portions 321, the guide block 32 can be specifically arranged between the second ends of the two movable blocks, and the two second guide portions 321 and the second limiting portion 322 are both arranged on opposite sides of the guide block 32, that is, second guide surfaces are formed on the opposite sides of the guide block 32, and a limiting block of the seat second limiting block is protruded on the end of the second guide surface.

[0108] In the embodiment in which the pen tip structure also includes an energy storage component 40, the energy storage component 40 is specifically arranged at a position between the guide block 32 and the pen tip 10. As described above, the energy storage component 40 and the case are separated and disposed on the first side and the second side of the guide block 32, respectively, for providing power for the energy storage component 40 to move in two opposite directions.

[0109] Please refer to Figures 3 to 7. In the embodiment where the trigger assembly 30 includes a button body 31 and a guide block 32, the pen tip 10 adopts a modular structure, which specifically includes a pen tip support tube 11 and a support frame 12. The pen tip support tube 11 mainly serves as an appearance component of the pen tip structure. Secondly, the pen tip support tube 11 is used to provide an assembly position for the pen tip portion 70 and the above-mentioned support frame 12, while the support frame 12 is used to provide an installation position for the above-mentioned trigger assembly 30, locking assembly 20 and other components.

[0110] Specifically, the nib support tube 11 has a hollow interior formed with an insertion cavity 111. A mounting port 112 communicating with the insertion cavity 111 is defined at one end of the nib support tube 11. A mounting portion 114 for mounting the nib 70 is defined at a second end of the nib support tube 11. Both the mounting cavity 121 and mounting port 122 are formed in the middle support frame 12. The support frame 12 can be inserted into the insertion cavity 111 through the mounting port 112 and mounted to the nib support tube 11. Furthermore, the support frame 12 can be removed from the insertion cavity 111 through the mounting port 112.

[0111] By setting the pen tip 10 to cooperate with the pen tip support tube 11 and the support frame 12, the trigger assembly 30, the locking assembly 20 and other components can be pre-installed and positioned on the support frame 12, and then uniformly assembled into the pen tip support tube 11 by the support frame 12, and the disassembly and assembly process is relatively simple and easy.

[0112] In an embodiment in which a spring clip 41 is provided between the energy storage component 40 and the pen tip 10, the spring clip 41 is provided between the pen tip support tube 11 and the support frame 12, and the first end of the spring clip 41 is installed on the outside of the support frame 12, and the support frame 12 is provided with a avoidance opening 124 connected to the mounting cavity 121. The energy storage component 40 passes through the avoidance opening 124, and a part of it is located in the mounting cavity 121 and acts on the trigger assembly 30 (guide block 32). The other part of the energy storage component 40 is located in the avoidance opening 124 or extends out of the support frame 12 through the avoidance opening 124 and is connected to the second end of the spring clip 41.

[0113] In the above scheme, the second end of the spring piece 41 can at least partially extend into the installation cavity 121 from the avoidance opening 124, and the above-mentioned deformation gap 411 is formed between the spring piece 41 and the cavity wall of the installation cavity 121, so that the spring piece 41 can be deformed relative to the support frame 12 and the pen tip support tube 11, and can limit its second end through the support frame 12, thereby protecting the structure of the spring piece 41.

[0114] In other embodiments, the spring piece 41 may also be installed in the installation cavity 121 or connected to the pen tip support tube 11 according to the design of the pen tip structure.

[0115] In combination with the above-mentioned embodiment in which the trigger assembly 30 includes a button body 31 and a guide block 32, and the pen tip 10 includes a pen tip support tube 11 and a support frame 12, in order to improve the compactness of the pen tip structure and the reliability of component assembly, and to facilitate the disassembly and assembly of the pen tip structure, please refer to Figures 6-7. A button hole 113 connected to the insertion cavity 111 is provided on the side of the support tube of the pen body 60, and an assembly hole 123 connected to the installation cavity 121 is provided on the side of the support frame 12. The assembly hole 123 includes a large hole portion 1231 and a small hole portion 1232 that are connected to each other.

[0116] During assembly and disassembly of the support frame 12 and the nib support tube 11, the support frame 12 is located within the insertion cavity 111 and has a disassembly position in which it is not fully assembled with the nib support tube 11, and an assembly position in which it is fully assembled with the nib support tube 11. When the support frame 12 is in the disassembly position, the large hole 1231 aligns with the assembly hole 123, allowing the key body 31 to be inserted into the installation cavity 121 through the key hole 113 and the large hole 1231. Correspondingly, the key body 31 can also be removed from the support frame 12 and the nib support tube 11 through the large hole 1231 and the assembly hole 123. When the support frame 12 is in the assembly position, the small hole 1232 aligns with the key hole 113, and the large hole 1231 is at least partially offset from the key hole 113, so that the key body 31 is at least partially constrained within the small hole 1232. Specifically, in the assembled state, the operating portion 311 is exposed from the nib support tube 11 through the key hole 113.

[0117] In this embodiment, the button body 31 includes the above-mentioned operating part 311, and a rod body part 312 connected to the operating part 311. One end of the rod body part 312 is connected to the operating part 311, and the other end is provided with a constraint part 313. Specifically, the structure of the operating part 311 matches the button hole 113, and the structure of the rod body part 312 matches the small hole part 1232. When the button body 31 is assembled with the pen tip support tube 11 and the support frame 12, it can perform pressing and resetting movements along the axial direction of the button hole 113 and the small hole part 1232. Please continue to refer to Figures 6 and 7. In the axial projection direction of the button body 31, the operating portion 311 and the constraint portion 313 are both larger than the small hole portion 1232, that is, the operating portion 311 and the constraint portion 313 are both larger than the rod body portion 312, and the constraint portion 313 is smaller than the large hole portion 1231. In this way, when the large hole portion 1231 is aligned with the button hole 113, the constraint portion 313 can penetrate into the installation cavity 121 through the large hole portion 1231, and the rod body portion 312 is placed in the large hole portion 1231. When the support rod moves further toward the assembly position, due to the structural matching between the button hole 113 and the operating portion 311, the button hole 113 will The radial freedom of the body 31 constitutes a constraint, thereby allowing the assembly hole 123 and the key body 31 to move relative to each other. When the key body 31 is fixed relative to the pen tip support tube 11, the small hole portion 1232 gradually moves toward the direction close to the rod body portion 312, and when the support frame 12 moves to the assembly position, the rod body portion 312 is placed in the small hole portion 1232. In this state, since the operating portion 311 and the constraint portion 313 are both larger than the small hole portion 1232, the axial freedom of the key body 31 is limited by the constraint portion 313 and the operating portion 311, so that the key body 31 can only be located in the small hole portion 1232 and move back and forth within the axial length distance range of the rod body portion 312.

[0118] On the contrary, during the disassembly of the support frame 12, the support frame 12 moves from the assembly position to the disassembly position, so that the large hole portion 1231 moves to a position opposite to the button hole 113, so that the button body 31 can be separated from the support frame 12 and the pen tip support tube 11 through the large hole portion 1231 and the button hole 113. After the button body 31 is separated from the above components, the support frame 12 can continue to move in the direction away from the assembly position, and finally separate from the insertion cavity 111 through the insertion port 112.

[0119] It should also be noted that in any of the above-mentioned embodiments, when the grounding component 50 is installed and matched with the locking component 20, the grounding component 50 is at least partially located in the installation cavity 121 and installed and matched with the locking component 20, and is exposed to the outside of the pen tip 10 through the installation opening 122, and is used to be connected to the negative pole of the battery 80 set in the pen body 60. In this state, the locking component 20 needs to maintain a connection relationship with the pen tip 10 to ensure the sequential connection between the grounding component 50, the locking component 20 and the pen tip 10, so that after the pen tip assembly is installed on the pen body 60, it is connected to the circuit board 90 through the pen body 60 to form a loop.

[0120] Please refer to Figures 10 to 12. This embodiment also provides a smart pen adopting the above-mentioned pen tip structure. The smart pen also includes a pen body 60. The pen body 60 can serve as the pen body 60 of the stylus pen described in the above-mentioned embodiment. Specifically, the pen body 60 can be set as a central-through structure, and a mounting structure 61 is provided on the inner wall of the pen body 60. The mounting structure 61 can be understood as the above-mentioned card slot located in the stylus pen body 60. The pen tip structure is mounted and matched with the pen body 60 through the locking assembly 20.

[0121] Please continue to refer to Figures 11-12. In one embodiment, a battery 80 and a circuit board 90 are also provided in the pen body 60. The battery 80 is used to power the circuit board 90. Module components with corresponding functions (such as an antenna module, a button module, a charging module, etc.) can be provided on the circuit board 90 according to the functional requirements of the smart pen. In the embodiment in which the pen tip assembly is provided with a grounding assembly 50, one end of the circuit board 90 is electrically connected to the positive pole of the battery 80, and the other end of the circuit board 90 is connected to the pen body 60. The grounding assembly 50 is provided on the locking assembly 20, one end of which is connected to the locking assembly 20, and the other end is connected to the negative pole of the battery 80. The locking assembly 20 is connected to the pen tip 10 to form a loop when the pen tip 10 is connected to the pen body 60, thereby realizing power supply to the circuit board 90.

[0122] According to the pen tip structure provided above, in the application of the smart pen, the pen tip 10 is located in the installation cavity 121 and is also provided with an energy storage component 40. The energy storage component 40 is a compression spring. The compression spring acts on the trigger assembly 30. The compression spring continuously applies a force to the locking assembly 20 to move toward the locking position through the trigger assembly 30. The locking assembly 20 includes two movable parts 21 that are cross-arranged and rotatably connected at the intersection. The rotation center of the two movable parts 21 is located between the first end and the second end of the two movable parts 21, wherein the first end of one movable part 21 forms a first locking portion 211, and the first end of the other movable part 21 forms a second locking portion 212. The first locking portion 211 and the second locking portion 212 are arranged opposite to each other, and the trigger assembly 30 can act on the second ends of the two movable parts 21 so that the first locking portion 211 and the second locking portion 212 can move synchronously around the rotation center in the direction of approaching or moving away from each other. The trigger assembly 30 continuously applies a force to the first locking portion 211 and the second locking portion 212 in the direction of moving away from each other through the compression spring. The first locking portion 211 and the second locking portion 212 are respectively provided with hooks 23 for snapping into engagement with the pen body 60 of the smart pen, and the two hooks 23 are extended in the direction of moving away from each other.

[0123] A first guide portion 214 is provided on one side opposite to the two movable members 21, and a second guide portion 321 is provided on two sides opposite to the two first guide portions 214 of the trigger assembly 30. The two second guide portions 321 are respectively guided and cooperated with the two first guide portions 214. The spacing between the two first guide portions 214 gradually increases from the first side of the movable member 21 to the second side, and the spacing between the two second guide portions 321 gradually increases from the first side to the second side of the trigger assembly 30. A first guide surface is formed on the first guide portion 214, and a second guide surface for pushing the first guide portion 214 is correspondingly formed on the second guide portion 321. The first guide surface and the second guide surface are parallel to each other and form surface contact. A compression spring is provided on the second side of the trigger assembly 30.

[0124] The first guide portion 214 is further provided with a first limiting portion 215, and the second guide portion 321 is provided with a second limiting portion 322 adapted to the first limiting portion 215. The first limiting portion 215 and the second limiting portion 322 are limitedly matched to limit the first limiting portion 215 and the second limiting portion 322 from moving in directions away from each other. The first limiting portion 215 is a limiting groove located at opposite ends of the first guide surface. Correspondingly, the second limiting portion 322 is a limiting block protruding from the trigger assembly 30 and located at opposite ends of the second guide surface. The limiting block is accommodated in the limiting groove to limit the movement of the first guide surface and the second guide surface in a direction away from each other.

[0125] Below, based on the specific structural form of the above-mentioned pen tip structure, a method for assembling the pen tip structure and the pen body 60 is provided:

[0126] 1. Press the button body 31 through the operating portion 311, so that the button body 31 pushes the guide block 32. During this process, the compression spring serving as the energy storage component 40 is compressed by the guide block 32.

[0127] Second, the guide block 32 pushes the second guide surface of the second guide portion 321 located on the second end of the movable member 21 and the second guide surface of the first guide portion 214 through the second guide surface of the second guide portion 321 located on opposite sides, so that the first guide portions 214 of the two movable members 21 move toward each other;

[0128] Third, both movable members 21 rotate about the rotation axis 22, causing the first locking portion 211 and the second locking portion 212 located at the first ends of the two movable members 21 to move toward each other. Driven by the first locking portion 211 and the second locking portion 212, the two hooks 23 are finally positioned in an unlocked position close to each other, allowing the second ends of the two movable members 21 to penetrate deeper into the pen body 60.

[0129] Fourth, by holding the nib support tube 11, push the entire nib structure toward the pen body 60, and insert the two hooks 23, and the first locking portion 211 and the second locking portion 212 for securing the two hooks 23, into the pen body 60 through the opening of the pen body 60;

[0130] Fifth, the pressure on the button body 31 is released. Without the external force applied by the user to the button body 31, the energy storage component 40 elastically recovers and pushes the guide block 32 toward the button body 31, so that the guide block 32 guides the second ends of the two movable members 32 to move away from each other, thereby causing the first locking portion 211 and the second locking portion 212 to respectively drive the two hooks 23 to move toward the locked position away from each other.

[0131] 6. Finally, the two hooks 23 are respectively inserted into the slots of the mounting structure 61 located in the pen body 60. At this time, the grounding component 50 located between the first locking portion 211 and the second locking portion 212 is pressed against the negative terminal of the battery located in the pen body 60 through the grounding spring 52, completing the assembly of the pen tip structure and the pen body 60.

[0132] According to the above-mentioned assembly process of the pen tip structure and the pen body 60, it can be understood that during the disassembly process of the pen tip structure and the pen body 60, the user only needs to re-apply pressure to the button body 31 through the operating part 311, so that it pushes the guide block 32 to compress the energy storage component 40, while driving the two movable parts 21 to move toward the unlocking position and disengage from the mounting structure 61 in the pen body 60. Only then can the pen tip structure be pulled out from the pen body 60 to complete the disassembly of the pen tip structure and the pen body 60.

[0133] In summary, this embodiment changes the pen tip structure to achieve assembly and disassembly with the stylus pen body 60, thereby improving the connection reliability between the pen tip structure and the pen body 60 in the application of the smart pen, making the smart pen product structure more stable and durable.
