[0030] Pens with removable refills are widely popular due to their convenient refill replacement feature. However, conventional refill connectors and refills are generally made of high-rigidity materials, such as hard engineering plastics like polycarbonate and acrylonitrile-butadiene-styrene copolymer, or metals like aluminum alloy. This results in a direct and unbalanced force transmission when inserting or removing the refill, creating a harsh feeling and negatively impacting the user experience.
[0031] To resolve the above technical issues, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a pen 1000 provided in one embodiment of this application. Figure 2This is a schematic diagram of the structure of a connector 100 provided in one embodiment of this application. This application provides a pen 1000, which can be an electromagnetic pen, a pencil with a removable lead, or a ballpoint pen, etc. The pen 1000 provided in this application includes a connector 100, a housing 200, and a lead 300. The end of the lead 300 is removably connected to the connector 100. The connector 100 is installed inside and connected to the housing 200. The connector 100 includes a groove 10, a connecting arm 20, and a connecting piece 30. The groove 10 is used to install and fix the end of the lead 300. One end of the connecting arm 20 is connected to the groove 10, and the other end of the connecting arm 20 is connected to the connecting piece 30. The connecting arm 20 is elastic. The connecting piece 30 is arranged around the outer periphery of the groove 10 and is connected to the housing 200.
[0032] In the technical solution of this application embodiment, the connecting arm 20 is elastic, and the elastic connecting arm 20 can constitute a buffer medium: when the user performs the insertion and removal operation of the pen refill 300, the force applied to the pen refill 300 can be transmitted to the connecting arm 20 through the groove 10, triggering the elastic deformation of the elastic connecting arm 20. This deformation process can absorb and dissipate part of the impact energy, which is beneficial to blocking the instantaneous impact force from being directly transmitted to the user's hand in the reverse direction, thereby effectively alleviating the harsh feedback generated by traditional rigid structures, and thus providing the user with a softer and more comfortable insertion and removal feel.
[0033] It should be noted that the elastic function of the connecting arm 20 can be achieved through various technical means. For example, the material of the connecting arm 20 can be selected from materials with good flexibility, resilience, and wear resistance, such as silicone, thermoplastic elastomers, polyurethane elastomers, natural rubber, nitrile rubber, etc. As another example, the connecting arm 20 can also be designed as a specific mechanical structure to achieve its elastic function. For instance, the connecting arm 20 itself or its key parts can be constructed as a spring structure. This spring structure can absorb and release energy using its own elastic deformation, thereby providing the required elastic function. Specific spring structure forms can include, but are not limited to: coil springs, leaf springs, torsion springs, or combinations thereof.
[0034] In some embodiments, the pen 1000 is an electromagnetic pen, capable of wirelessly interacting with external receiving devices (such as graphics tablets, drawing screens, etc.) through electromagnetic induction. The pen 1000 also includes an inductor assembly and a PCB assembly. The inductor assembly includes magnetic elements such as magnetic cores or magnetic rings, which enhance the electromagnetic induction intensity within the pen 1000, ensuring stable electromagnetic coupling between the pen 1000 and the external receiving device during operation, thereby improving positioning accuracy and signal transmission sensitivity. The PCB assembly includes a PCB circuit board and a bracket for housing and fixing the PCB circuit board. Various electronic components (such as chips, resistors, capacitors, etc.) are integrated on the PCB circuit board, responsible for processing the electromagnetic signals transmitted by the inductor assembly, parsing instructions from external devices, and controlling the overall operating logic of the pen 1000 (such as pressure sensitivity adjustment, function switching, etc.).
[0035] In some embodiments, please refer to Figure 2 and Figure 3 , Figure 3 yes Figure 2 The structural diagram of the connector 100 provided in the embodiment from another angle shows that the connector 30 includes a body 31, which is a ring structure; the body 31 and the groove 10 are spaced apart; the connecting arm 20 is connected to the inner ring of the body 31; the port 14 of the groove 10 protrudes from the body 31, and the connection between the connecting arm 20 and the groove 10 is located between the body 31 and the port 14 of the groove 10.
[0036] In the embodiments of this application, through the above structural design, when the pen refill 300 is inserted, the elastic connecting arm 20 will deform in the same direction as the insertion of the pen refill 300, and the space between the body 31 and the groove 10 can provide sufficient room for the deformation of the connecting arm 20. This design can reduce the probability of the connecting arm 20 colliding with surrounding components, thereby helping to maintain the buffering effect of the connecting arm 20.
[0037] In some embodiments, the connecting piece 30 further includes a plurality of hooks 32, which are connected to the outer ring of the body 31 and are spaced apart along the outer ring of the body 31.
[0038] In the embodiments of this application, the connecting piece 30 can be mounted on the housing 200 via multiple hooks 32 to form a stable support structure, thereby effectively fixing the position of the connector 100 within the housing 200 and reducing the probability of it shaking or shifting during the use of the pen 1000 or the insertion and removal of the pen refill 300, thus improving the overall structural stability. For example, the number of hooks 32 can be 2, 3, 4, etc., and those skilled in the art can make corresponding settings as needed.
[0039] In some embodiments, such as Figure 2As shown, there is one connecting arm 20, which is arranged around the outer periphery of the groove 10.
[0040] In the embodiments of this application, there is only one connecting arm 20, that is, a single connecting arm 20 surrounds the groove 10, which makes the elastic support force evenly distributed in the entire circumferential direction of the groove 10. No matter which direction the user applies force to insert or remove the pen refill 300, or if the pen refill 300 is subjected to non-axial lateral force during the insertion or removal process, this surrounding connecting arm 20 can provide effective elastic support and cushioning, thereby reducing local stress concentration and making the user's operation feel smoother and softer.
[0041] In some embodiments, please refer to Figure 4 , Figure 4 This is a schematic diagram of the structure of a connector 100 provided in another embodiment of this application. There are multiple connecting arms 20, each arranged at intervals along the outer periphery of the groove 10. For example, the number of connecting arms 20 can be 2, 3, 4, 5, 6, etc. The arm length, thickness, and shape of each connecting arm 20 can be the same or differentiated. Those skilled in the art can make the settings according to actual needs.
[0042] In the embodiments of this application, by setting multiple spaced connecting arms 20, the spaced arrangement can avoid other components inside the housing 200, thereby more flexibly adapting to the complex structure of the housing 200 and improving space utilization. At the same time, the spaced design can also reduce the amount of material used in the connecting arms 20, reduce manufacturing costs, and reduce the weight of the connector 100, which is in line with the development trend of lightweight pens.
[0043] In some embodiments, please refer to Figure 5 , Figure 5 yes Figure 2 A cross-sectional view of the connector 100 provided in the embodiment shows that the groove 10 includes a first groove wall 11, a second groove wall 12, and a groove bottom wall 13; the second groove wall 12 is located at the end of the first groove wall 11 away from the groove bottom wall 13; in the direction away from the groove bottom wall 13, the cross-sectional area of the space enclosed by the second groove wall 12 gradually increases.
[0044] In the embodiments of this application, by setting the space enclosed by the second groove wall 12 to have a gradually expanding conical opening structure, the area of initial contact of the pen refill 300 can be significantly increased. Even if there is a small positional or angular deviation when the pen refill 300 is inserted, it can be captured and guided into the groove by the conical opening structure, making it easier for the pen refill 300 to enter the groove 10, thereby improving the user's operating experience.
[0045] In some embodiments, at least one of the groove 10, connecting arm 20, and connecting piece 30 is made of silicone.
[0046] In the embodiments of this application, it is understood that silicone has good resilience and low hardness. By using silicone as the material for at least one of the groove 10, the connecting arm 20, and the connecting piece 30, the elasticity of the connector 100 can be significantly enhanced. This design allows the connector 100 to more effectively absorb and buffer impact forces during the insertion and removal of the pen refill 300, further improving user comfort; at the same time, the silicone material can also reduce friction and collision between components, extending the service life of the connector 100. In addition, the use of silicone material also helps to reduce production costs, meeting the needs of industrial production.
[0047] In some embodiments, please refer to Figure 6 , Figure 6 yes Figure 1 The partial exploded view of the pen 1000 provided in the embodiment shows that the housing 200 includes a first sub-housing 201 and a second sub-housing 202, and the connector 100 is disposed between the first sub-housing 201 and the second sub-housing 202. The first sub-housing 201 has a first through hole 2011 through which the pen refill 300 passes, and the second sub-housing 202 has a second through hole 2021 for the groove 10 to move.
[0048] In the embodiments of this application, the housing 200 adopts a split design of a first sub-housing 201 and a second sub-housing 202, which facilitates the precise installation of internal components such as the connector 100 between the two, thereby reducing the overall assembly difficulty. At the same time, the split structure also facilitates subsequent inspection or replacement of internal components, improving maintenance convenience. The first through hole 2011 opened in the first sub-housing 201 provides a clear insertion and removal channel for the pen refill 300, which can guide the pen refill 300 to enter and exit the slot 10 of the connector 100 along a preset path, reducing the probability of deviation or skew during insertion and removal of the pen refill 300, and helping to improve the accuracy of insertion and removal operations. The second through hole 2021 opened in the second sub-housing 202 provides movement space for the slot 10. Combined with the elastic characteristics of the connecting arm 20, when the slot 10 is displaced due to the force of pen refill 300 insertion and removal, the second through hole 2021 can reduce the obstruction of the housing 200 on the movement of the slot 10, ensuring that the connecting arm 20 can freely realize elastic buffering action, thereby helping to ensure the functional effectiveness of the buffer structure.
[0049] In some embodiments, the connecting piece 30 includes a body 31 and a plurality of hooks 32, the hooks 32 being connected to the outer periphery of the body 31; wherein, the plurality of hooks 32 include at least a first hook 321 and a second hook 322 disposed opposite to each other, the first hook 321 and the second hook 322 being mounted on the second sub-shell 202.
[0050] In the embodiments of this application, the connecting piece 30 forms a symmetrical support structure by adopting a first hook 321 and a second hook 322 that are arranged opposite to each other. This structure can provide balanced support from both sides, effectively reducing the probability of the connector 100 tilting or shifting within the housing 200, and ensuring the stability and balance of the overall structure. In particular, when the pen refill 300 is subjected to lateral force during insertion and removal, the symmetrical support can counteract the eccentric force, thereby further improving the stability of the overall structure.
[0051] In some embodiments, the plurality of loops 32 may also include a third loop, a fourth loop, etc., and those skilled in the art can make corresponding settings as needed.
[0052] In some embodiments, the groove 10, the connecting arm 20, and the connecting piece 30 are integrally formed.
[0053] In the embodiments of this application, the groove 10, connecting arm 20, and connecting piece 30 adopt an integral molding structure, eliminating splicing gaps and weak points between components, making the three form a unified whole with consistent mechanical properties. During the insertion and removal of the pen refill 300, the force transmission is more direct and smooth, effectively resisting fatigue damage caused by repeated deformation, reducing the risk of breakage and detachment, and significantly enhancing the overall structural strength and service life of the connector 100. In addition, the integral molding process can complete the manufacturing of the three components at one time, eliminating the assembly steps (such as welding, snap-fit connection, etc.) after producing each component separately, greatly shortening the production cycle, reducing labor and equipment costs, and better adapting to the needs of large-scale mass production.
[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
