Detailed Implementation

[0075] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0076] Traditional rechargeable stylus designs typically house the battery internally, making it non-removable and non-replaceable. The pen body features a charging port (usually USB, Type-C, or POGO-PIN) or an internal wireless transceiver coil, along with a built-in charging circuitry to charge the rechargeable battery. However, when the battery experiences excessive charging cycles, accidental drops, or premature wear and tear, users cannot replace it themselves, leading to reduced battery life or even complete malfunction. Furthermore, when the stylus battery is depleted and the user wants to use it immediately, they must wait for the rechargeable battery to charge before continuing to use the stylus, making it inconvenient to remove and replace the battery.

[0077] First aspect

[0078] In view of this, embodiments of this application provide an electronic pen 200 to overcome at least one of the above-mentioned technical problems.

[0079] Referring to Figure 1, in this embodiment, the electronic pen 200 includes a pen body 10, a first connector 20, and a power module 30. The pen body 10 has a receiving cavity 11. The first connector 20 is connected to the pen body 10, and at least a portion of the first connector 20 is disposed within the receiving cavity 11. Specifically, a portion of the first connector 20 may be located within the receiving cavity 11, while another portion may be located outside the receiving cavity 11; alternatively, the first connector 20 may be completely disposed within the receiving cavity 11. The power module 30 includes a module body 31 and a second connector 32 connected to each other. The second connector 32 is detachably connected to the first connector 20. The module body 31 can be a common battery or a rechargeable battery. Because it is detachably connected to the pen body 10 via the first connector 20 and the second connector 32, the module body 31 can be removed for replacement. In this design, the power module 30's module body 31 is connected to the first connector 20 via the second connector 32, and the first connector 20 is in turn connected to the pen body 10. Therefore, the power module 30 is effectively connected to the pen body 10. The second connector 32 and the first connector 20 are detachably connected, allowing the power module 30 to be both connected to and easily removed from the pen body 10. When the power module 30 runs out of power, it can be removed and replaced with a new one, allowing the electronic pen 200 to continue operating.

[0080] Optionally, the first connector 20 and the second connector 32 may include one of the electrical connection methods such as a pogo pin connector, a B to B connector, or a terminal block connector.

The module body 31 is partially embedded inside the receiving cavity 11, dividing the module body 31 into two parts: the first segment 312 and the second segment 313. The first segment 312 is located inside the receiving cavity 11 and is connected to the side of the second connector 32 away from the first connector 20; the second segment 313 is located outside the receiving cavity 11 and is connected to the side of the first segment 312 away from the second connector 32.

[0085] Referring to Figures 3 and 4, in some embodiments, the power module 30 further includes a first housing 33. The first housing 33 has a first connecting cavity 331 and a second through hole 332 communicating with the first connecting cavity 331. The second segment 313 is embedded in the first connecting cavity 331, thereby allowing the first housing 33 to provide some protection for the second segment 313. The charging interface 311 communicates with the second through hole 332. Specifically, when the module body 31 is partially embedded inside the receiving cavity 11, the first housing 33 is sleeved on the second segment 313 located outside the receiving cavity 11, providing protection for the second segment 313. At the same time, the second through hole 332 is provided on the first housing 33, and the second through hole 332 communicates with the charging interface 311 provided on the second segment 313, thereby facilitating the charging plug to pass through the second through hole 332 and connect to the charging interface 311 to charge the module body 31.

[0086] Referring to Figures 5 and 6, in some embodiments, the first connector 20 includes a main body 21 and a connecting portion 22. The main body 21 is located inside the receiving cavity 11 and is connected to the pen body 10. At least a portion of the connecting portion 22 is located outside the receiving cavity 11, and the connecting portion 22 is connected to the side of the second connector 32 away from the module body 31. That is, the first connector 20 may have one part located inside the receiving cavity 11 and another part located inside and outside the receiving cavity 11; by dividing the first connector 20 into a main body 21 and a connecting portion 22, with the main body 21 located inside the receiving cavity 11 and connected to the pen body 10, and at least a portion of the connecting portion 22 located outside the receiving cavity 11, the portion of the connecting portion 22 located outside the receiving cavity 11 can be detachably connected to the second connector 32, then the module body 31 and the second connector 32 are also located outside the receiving cavity. This arrangement also allows the module body 31 to be detached from the electronic pen 200 for replacement.

[0087] Referring to Figures 5 and 6, in some embodiments, the power module 30 further includes a second housing 34. The second housing 34 has a second connecting cavity 341. The module body 31 and the second connector 32 are both embedded in the second connecting cavity 341, and at least a portion of the connecting part 22 is embedded in the second connecting cavity 341 and connected to the side of the second connector 32 away from the module body 31. The module body 31 is provided with a charging interface 311. The module body 31 and the second connector 32 are located outside the receiving cavity 11 and are simultaneously embedded in the second connecting cavity 341 of the second housing 34, providing some protection for the module body 31 and the second connector 32. The portion of the connecting part 22 located outside the receiving cavity 11 is embedded in the second connecting cavity 341 and is detachably connected to the second connector 32 located in the second connecting cavity 341, allowing the module body 31 and the second connector 32 to be detached from the electronic pen 200 for replacement.

[0088] Referring to Figures 5 and 6, in some embodiments, the second outer shell 34 has a third through hole 342 communicating with the second connecting cavity 341, and the third through hole 342 communicating with the charging interface 311. Specifically, the third through hole 342 is formed on the second outer shell 34, communicating with the second connecting cavity 341 of the second outer shell 34, and the charging interface 311 is provided on the module body 31, which is located inside the second connecting cavity 341.

[0089] Therefore, the charging interface 311 is also located inside the second connecting cavity 341. The charging interface 311 is set facing the third through hole 342, so that the third through hole 342 is connected to the charging interface 311, making it convenient for the charging plug to pass through the third through hole 342 and connect to the charging interface 311 to charge the module body 31.

[0090] In some embodiments, the first connector 20 and the second connector 32 are any one of magnetic adsorption connection, snap-fit ​​connection, and threaded connection. Specifically, the first connector 20 and the second connector 32 can each be two magnets connected by magnetic adsorption, allowing the power module 30 to be easily detached from the electronic pen 200. The first connector 20 can have a slot structure, and the second connector 32 can have a snap-fit ​​structure, allowing the first connector 20 and the second connector 32 to be snap-fit ​​connected. Alternatively, the first connector 20 can have a threaded groove structure, and the second connector 32 can have a threaded block structure, allowing the first connector 20 and the second connector 32 to be threaded connected.

[0092] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0093] Second aspect

[0094] As shown in Figures 10 to 19, this application proposes an electronic pen 200, which includes a base 110 and a cover 120.

[0095] As shown in Figures 11 and 12, the base 110 includes a pen body 10, a first connector 20, and a power module 30. The pen body 10 is provided with a first bracket 112, and the power module 30 is connected to the first bracket 112. The power module 30 has a charging interface 311; the charging interface 311 is used for charging or information transmission. The electrical connection terminals of the charging interface 311 are used for external electrical connection, so that the electronic pen 200 can charge or transmit information with the outside world. The charging interface 311 can be configured as any suitable interface such as a Type-A interface (Universal Serial Bus Type A interface), a Type-B interface (Universal Serial Bus Type B interface), a Type-C interface (Universal Serial Bus Type C interface), a Micro-USB interface (Micro Universal Serial Bus interface), or a Lightning interface.

[0096] As shown in Figures 12 and 13, the cover 120 and the base 110 are disposed opposite each other along the first direction X. The cover 120 can switch between a first position, a second position, and a third position relative to the first support 112 along the first direction X. In the first position, the cover 120 covers the charging interface 311. In the second position, the charging interface 311 is exposed on the cover. The third position is located between the first position and the second position along the first direction X. The driving member 130 includes a first magnet 131 and a second magnet 132. The first magnet 131 is connected to the base 110, and the second magnet 132 is connected to the cover 120. During the switching of the cover 120 between the first position and the second position, the first magnet 131 can sense the second magnet 132 to generate a driving force. The magnetic interaction between the first magnet 131 and the second magnet 132 when the cover 120 is located between the first position and the third position is opposite to the magnetic interaction between the first magnet 131 and the second magnet 132 when the cover is located between the third position and the second position. Users can perceive the actual movement position of the cover by the changes in the magnetic interaction between the first magnet 131 and the second magnet 132. That is, the force feedback from the driving member 130 to the user when the cover 120 switches between the first and third positions is different from the force feedback when the cover 120 switches between the second and third positions. This technical solution allows users to perceive different segments of the cover 120's movement, improving the tactile feedback and control accuracy of the cover 120's opening and closing. The driving member 130 can be connected to the cover 120 or to the base 110. The first magnet 131 can be configured as a plate magnet, a U-shaped magnet, or a ring magnet. The first magnet 131 can be a single magnet or a magnetic assembly formed by multiple magnets. Correspondingly, the second magnet 132 can also be any suitable shape and number of magnets, which will not be elaborated here.

[0097] In the first position, the cover 120 can be engaged with the base 110. In some embodiments, the driving force of the drive member 130 can serve as the initial power for the cover 120 to move along the first direction X, meaning that the drive member 130 can trigger the cover 120 to switch from the first position to the second position. In some embodiments, the cover 120 can also be triggered by an external force, with the drive member 130 providing driving force to the cover 120 at any suitable position within the travel distance of the cover 120 along the first direction X to assist the cover 120 in moving along the first direction X. Further, in some embodiments, the drive member 130 can also drive the cover 120 to move in the opposite direction of the first direction X to improve the ease of closing the cover 120. The triggering of opening and closing of the cover 120 can vary depending on different usage requirements. The triggering of opening and closing of the cover 120 can be achieved by providing a specific trigger sensor, which can generate a trigger signal, and then control the drive member 130 to drive the cover 120 through the trigger signal. The cover 120 can also be engaged with the base 110 at the end positions of the first and second positions. The user provides an initial driving force to the cover 120 to release the engagement between the cover 120 and the base 110, thereby triggering the cover 120 so that the driving member 130 can drive the cover 120 to move along the first direction X, which greatly improves the convenience and stability of opening the cover 120.

[0098] As shown in Figures 14 and 15, in this embodiment, the cover 120 has a first position covering the charging interface 311 and a second position exposing the charging interface 311. The driving member 130 includes a first magnet 131 and a second magnet 132. The first magnet 131 is connected to the base 110, and the second magnet 132 is connected to the cover 120. The first magnet 131 can sense and generate a driving force with the second magnet 132 to drive the cover 120 to switch between the first position and the second position. When the cover 120 is in the first position covering the charging interface 311, the cover 120 is fastened to the base 110. Depending on the relative position of the first magnet 131 and the second magnet 132, as the cover 120 moves along the first direction X, the distance between the first magnet 131 and the second magnet 132 can increase or decrease. Since magnetic poles with the same polarity will repel each other and magnetic poles with opposite polarities will attract each other, the first magnet 131 and the second magnet 132 can adjust the relative positions of the magnetic poles, and the mutual attraction or repulsion between the first magnet 131 and the second magnet 132 can drive the cover 120 to move relative to the base 110.

[0099] As shown in Figures 16 and 17, in some embodiments, in the first position, the second magnet 132 is located on the side of the first magnet 131 near the rod 113. In the second position, along a direction perpendicular to the first direction shown, the first magnet 131 and the second magnet 132 are at least partially overlapped. When the cover 120 is located between the first and third positions, the first magnet 131 and the second magnet 132 repel each other. When the cover 120 is located between the third and second positions, the first magnet 131 and the second magnet 132 attract each other. That is, in the first position, the second magnet 132 is located on the side of the first magnet 131 near the rod 113, and the magnetic polarities of the adjacent ends of the first magnet 131 and the second magnet 132 are the same.

[0100] Specifically, as shown in Figures 16 and 17, the two ends of the second magnet 132 arranged opposite each other along the first direction X are a first end 1321 and a second end 1322, with the first end 1321 located on the side of the second end 1322 near the rod 113. The two ends of the first magnet 131 arranged opposite each other along the first direction X are a third end 1311 and a fourth end 1312, with the third end 1311 located on the side of the fourth end 1312 near the rod 113. In the first position, the second end 1322 is located on the side of the third end 1311 near the rod 113. The magnetic polarities of the second end 1322 and the third end 1311 are the same. Specifically, in some embodiments, the first end 1321 and the fourth end 1312 can be configured as S poles (south pole), and the second end 1322 and the third end 1311 can be configured as N poles (north pole). In some embodiments, the first end 1321 and the fourth end 1312 can be configured as the N pole (north pole), and the second end 1322 and the third end 1311 can be configured as the S pole (south pole). That is, in the first position, the second end 1322 and the third end 1311 repel each other, and the repulsive force between the second end 1322 and the third end 1311 can improve the stability of the cover 120 fastening to the base 110. When the cover 120 switches from the first position to the third position, the cover 120 is driven along the first direction X. Under the action of the initial driving force, the cover 120 moves along the first direction X. The relative distance between the second end 1322 and the third end 1311 decreases. At the same time, the relative distance between the first end 1321 and the third end 1311, as well as the relative distance between the second end 1322 and the fourth end 1312, also decreases. The second end 1322 and the third end 1311 repel each other, but the first end 1321 and the third end 1311 attract each other, and the second end 1322 and the fourth end 1312 attract each other. When the cover 120 moves to the third position along the first direction X, the repulsive force between the second end 1322 and the third end 1311 is less than the attractive force between the first end 1321 and the third end 1311, and between the second end 1322 and the fourth end 1312. Therefore, the attractive force between the first magnet 131 and the second magnet 132 is greater than the repulsive force, and the combined force of the first magnet 131 and the second magnet 132 is attractive. This allows the first magnet 131 and the second magnet 132 to drive the cover 120 to move actively away from the rod 113. During closing, as the cover 120 moves closer to the rod 113, the attractive force is less than the repulsive force, and the combined force between the first magnet 131 and the second magnet 132 is mutually repulsive. This allows the first magnet 131 and the second magnet 132 to assist the cover 120 in closing. The arrangement of the first magnet 131 and the second magnet 132 allows the repulsive and attractive forces of the first magnet 131 and the second magnet 132 to provide feedback for the opening and closing process of the cover 120 as the position of the cover 120 changes, so that the user can obtain a better feel for opening and closing.On the other hand, the first magnet 131 and the second magnet 132 can provide the driving force for opening or closing the cover 120 to assist in opening and closing the cover 120 and improve the convenience of opening and closing the cover 120.

[0101] In other embodiments, in the first position, the first magnet 131 and the second magnet 132 are at least partially overlapped along a direction perpendicular to the first direction. In the second position, the second magnet 132 is located on the side of the first magnet 131 away from the rod. When the cover 120 is between the first and third positions, the first magnet 131 and the second magnet 132 attract each other. When the cover 120 is between the third and second positions, the first magnet 131 and the second magnet 132 repel each other. During the movement of the cover 120 from the first position to the third position, an external driving force overcomes the attractive force between the first magnet 131 and the second magnet 132 to propel the cover 120 along the first direction. When the cover 120 moves to the third position, the repulsive force between the first magnet 131 and the second magnet 132 forms a driving force to drive the cover 120 to move further to the second position. In the first position, the magnetic poles between the first magnet 131 and the second magnet 132 can be selected according to the different requirements of the magnetic interaction between the first magnet 131 and the second magnet 132, which will not be elaborated here.

[0102] As shown in Figure 15, to further improve the stability of the connection between the cover 120 and the base 110, in some embodiments, the base 110 further includes a rod 113. The rod 113 is connected to the side of the first support 112 away from the cover 120. The driving member 130 further includes a third magnet 133. The cover 120 has an opening for the first support 112 to pass through and a bottom wall 124 disposed opposite to the opening along the first direction X. The third magnet 133 is connected to the bottom wall 124. The magnetic polarity of the side of the first magnet 131 away from the rod 113 is opposite to the magnetic polarity of the side of the third magnet 133 close to the rod 113. The end of the first magnet 131 near the bottom wall 124 is the fourth end 1312. When the fourth end 1312 is the S pole (south pole), the magnetic polarity of the third magnet 133 near the first magnet 131 is the N pole (north pole). When the fourth end 1312 is the N pole (north pole), the magnetic polarity of the third magnet 133 near the first magnet 131 is the S pole (south pole). In the first position, the cover 120 can be fastened to the base 110, and the third magnet 133 can abut against the base 110. The first magnet 131 and the third magnet 133 can attract each other to improve the connection stability between the cover 120 and the base 110.

[0103] During the opening and closing of the cover, the magnet moves relative to other components. During this process, the magnet comes into direct contact with these moving components and is subjected to force, which easily leads to wear and tear on the magnet, thus affecting its lifespan. To reduce magnetic force changes caused by magnet wear, in some embodiments, the magnet can be housed in an independent receiving cavity, avoiding friction between the magnet and the walls of other components and improving the lifespan of the cover 120. As shown in Figures 12 and 13, in some embodiments, the base 110 includes a first support 112 with a first receiving cavity 1121. A first magnet 131 is disposed in the first receiving cavity 1121, so that the first magnet 131 is spaced apart from the cover 120. As shown in Figures 12 and 13, in some embodiments, the cover 120 includes a second support 123 with a second receiving cavity 1231. A second magnet 132 is disposed in the second receiving cavity 1231, so that the second magnet 132 is spaced apart from the base 110. The opening of the second receiving cavity 1231 can be located on the side of the second bracket 123 opposite to the first magnet 131. The first magnet 131 and the cover 120 are spaced apart. Specifically, the cover assembly 100 can space the first magnet 131 and the cover 120 apart through the assembly gap, or the first bracket 112 can separate the first magnet 131 and the cover 120. During the opening and closing of the cover 120, there is no friction between the first magnet 131 and the cover 120, which greatly improves the service life of the drive component 130 and the cover 120.

[0104] To improve the stability of the cover 120 moving along the first direction X, as shown in FIG16, in some embodiments, the cover 120 defines a third receiving cavity 121. The cover 120 also includes a second support 123. Both the first support 112 and the second support 123 can pass through the third receiving cavity 121 along the first direction X. The second support 123 is configured with a material responsive to the magnetic field of the first magnet 131. The magnetic field-responsive material can be iron, nickel, cobalt, and their alloys and compounds. The magnetic field-responsive material can be a hard magnetic material, a soft magnetic material, or a rectangular magnetic material. The second support 123 is configured with a material responsive to the magnetic field of the first magnet 131. The first magnet 131 can attract the second support 123, thereby enabling the second magnet 132 and the second support 123 to jointly restrict the movement of the cover 120 relative to the base 110 and reduce the impact force between the cover 120 and the base 110. Thanks to the application of magnets, the sliding damping effect between the cap 120 and the base 110 is significantly improved. The damping force generated by the magnetic field helps control the speed of the cap 120 when opening and closing, reducing unnecessary vibration and noise, thereby stabilizing the system's position and preventing system failure or performance degradation due to excessive vibration. The interaction between the magnet and the magnetic material can precisely control the opening and closing stroke of the pen cap, improving the accuracy and stability during use and preventing accidental opening or closing of the pen cap.

[0105] As shown in Figures 16, 18, and 19, in some embodiments, the drive member 130 further includes an elastic member 136. The cover 120 has a first position covering the connecting portion 111 and a second position exposing the charging interface 311. In the first position, the elastic member 136 is compressed or stretched so that the drive member 130 can provide a driving force to the cover 120 in a first direction X. The elastic member 136 can be used to assist the first magnet 131 and the second magnet 132 in driving the cover 120 to open or close, thereby helping to reduce the volume of the first magnet 131 and the second magnet 132, reducing the cost and volume of the cover assembly 100, and improving the structural compactness of the cover assembly 100. In some embodiments, the drive member 130 may include, in addition to components capable of driving the cover 120 by magnetic force, components capable of driving the cover 120 by elastic force or components capable of driving the cover 120 by electricity. Specifically, the drive member 130 may also include a micro linear motor, a micro hydraulic drive mechanism, or a micro linear cylinder, etc. A linear drive unit is provided, the output end of which is connected to the cover 120, and the cover 120 is connected to the base 110, so that the linear drive unit can push the cover 120 to move along the first direction X.

[0106] Optionally, the base 110 includes a first support 112 and a rod 113. The first support 112 is connected to the rod 113, and a connecting portion 111 is provided on the first support 112. The first support 112 can pass through the third receiving cavity 121. The driving member 130 includes a first elastic portion 134. One end of the first elastic portion 134 is connected to the side of the rod 113 near the first support 112, and the other end is connected to the first support 112. In the first position, the first support 112 compresses the first elastic portion 134. In some embodiments, the cover 120 has an opening communicating with the third receiving cavity 121 and a bottom wall 124 disposed opposite to the opening along a first direction X. The driving member 130 includes a second elastic portion 135. One end of the second elastic portion 135 is connected to the side of the first support 112 away from the rod 113, and the other end is connected to the bottom wall 124. In the first position, the cover 120 compresses the second elastic portion 135. In some embodiments, the elastic element 136 may also be connected to the first bracket 112. In the first position, the cover 120 abuts against the end of the elastic element 136 away from the rod 113, so that the elastic element 136 is compressed. In some embodiments, one end of the elastic element 136 may be connected to the end of the first bracket 112 near the cover 120, and the other end may be connected to the end of the cover 120 near the rod 113. In the first position, the elastic element 136 is stretched. Specifically, in the first position, the cover 120 may engage with the base 110 so that the cover 120 can be held in the first position. When the engagement between the cover 120 and the base 110 is released, the cover 120 can move to the side away from the base 110 under the drive of the elastic element.

[0107] As shown in Figures 13 and 15, to further improve the protection of the connecting part 111 and reduce the risk of damage to the connecting part 111, the base 110 may also be provided with an inner shell 118. Accordingly, the inner shell 118 can extend into the third receiving cavity 121 to further improve the connection stability between the cover 120 and the base 110. In order to reduce the wear and tear of the cover 120, the inner shell 118 can be spaced apart from the second bracket 123. The base 110 also includes an inner shell 118 and a first support 112. A connecting portion 111 is disposed on the first support 112. The inner shell 118 is sleeved on the first support 112. The cover 120 also includes an outer shell 122. The outer shell 122 defines a third receiving cavity 121. A second support 123 passes through the third receiving cavity 121 and is connected to the outer shell 122, so that the third receiving cavity 121 is divided into an inner chamber and an outer chamber. Specifically, the outer chamber is disposed on the side of the second support 123 near the outer shell 122, and the inner chamber is disposed on the side of the second support 123 away from the outer shell 122. The first support 112 can pass through the inner chamber, and the inner shell 118 can pass through the outer chamber. The inner shell 118 and the second support 123 are spaced apart along the first direction X and / or along a direction perpendicular to the first direction X. In other words, along a direction perpendicular to the first direction X, the inner shell 118 and the first bracket 112 are spaced apart, and an assembly gap is maintained between the inner shell 118 and the second bracket 123. The cover 120 may have an outer shell 122, which defines a third receiving cavity 121. The second bracket 123 passes through the third receiving cavity 121. The outer shell 122 may abut against the inner shell 118, and the outer shell 122 may also abut against other shells of the base 110 besides the inner shell 118 to improve the sealing performance of the outer shell 122. There are no restrictions on this.

[0108] The cover 120 can be held in a first position in any suitable manner so that the cover 120 remains engaged with the base 110 without being triggered. The cover 120 can also be held in a second position in any suitable manner so that the cover 120 remains exposed to the charging interface 311 without being triggered.

[0109] Specifically, in some embodiments, the cover 120 can be directly restricted by the driving member 130 to keep the cover 120 in a first position or a second position, which will not be elaborated here. As shown in FIG14, in some embodiments, the base 110 has a first latching portion 114, and the cover 120 has a second latching portion 125. The first latching portion 114 can latch onto the second latching portion 125 to restrict the cover 120 to the first position or the second position. If the first latching portion 114 can be configured as a protrusion, the corresponding second latching portion 125 is configured as a groove. If the first latching portion 114 can be configured as a groove, the corresponding second latching portion 125 is configured as a protrusion.

[0110] To further improve the stability of the cover 120 moving along the first direction X and reduce the risk of the cover 120 detaching from the base 110, as shown in Figures 14 and 15, in some embodiments, the cover 120 has a first groove 126 extending along the first direction X, and the base 110 has a first protrusion 115 passing through the first groove 126, so that the base 110 can slide relative to the cover 120 along the first groove 126. As shown in Figures 16 and 17, in some embodiments, the base 110 has a second groove 116 extending along the first direction X, and the cover 120 has a second protrusion 127 passing through the second groove 116, so that the cover 120 can slide relative to the base 110 along the second groove 116.

[0111] As shown in Figure 13, to improve the internal connection stability of the electronic pen 200, the circuit board inside the electronic pen 200 can be configured as a flexible circuit board. Specifically, the pen body also has a flexible printed circuit board 117 and an indicator light (not shown in the figure). Along the first direction X, one end of the flexible printed circuit board 117 is connected to the power module 30, and the other end is connected to the indicator light. The indicator light is used to display the working status of the charging interface 311, so that the user can observe whether the charging interface 311 is in an unconnected position, a charging position, a discharging position, or a data transmission position. In some embodiments, the cover 120 may also include a sensor, which is electrically connected to the flexible circuit board, so that the cover assembly 100 can trigger the closing of the cover 120 through the connection position of the charging interface 311 with the external device, or identify the movement distance of the cover 120, thereby facilitating the automation of the movement control of the cover 120 and improving the correlation of each part of the cover assembly.

[0112] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0113] Third aspect

[0114] The electronic pen 200 is an important input accessory for electronic products. It consists of a tip, a barrel, and a tail, with a cover typically located at the tail to protect the pen's connection terminals. The stability of the tail structure directly affects the pen's charging performance and lifespan. The cover can slide onto the barrel, exposing the connection terminals when in use. Alternatively, the cover can snap onto the barrel, allowing direct separation during use. In existing technology, whether the cover slides onto the barrel or snaps onto it, the contact impact between the cover and the barrel is generally significant during the opening and closing motion, easily causing electrical connections at the terminals to break and damaging the tail structure.

[0115] To solve the above-mentioned technical problems, as shown in Figures 20 to 25, this application proposes an electronic pen 200, which includes a base 110 and a cover 120.

[0116] As shown in Figures 20, 21, and 22, the base 110 includes a pen body 10, a first connector 20, and a power module 30. The power module 30 has a charging interface 311. The pen body 10 is provided with a first limiting part 112a, and the charging interface 311 is provided with electrical connection terminals. The charging interface 311 is used for external electrical connection so that the electronic pen 200 can charge, discharge, or transmit information with the outside world. The charging interface 311 can be configured as any suitable interface such as a Type-A interface (Universal Serial Bus Type A interface), a Type-B interface (Universal Serial Bus Type B interface), a Type-C interface (Universal Serial Bus Type C interface), a Micro-USB interface (Micro Universal Serial Bus interface), or a Lightning interface.

[0117] As shown in Figures 21, 22, and 23, the cover 120 and the base 110 are disposed opposite each other along the first direction X. The cover 120 includes a second limiting portion 121a and defines a fourth receiving cavity 122a. The power module 30 can pass through the fourth receiving cavity 122a. The cover 120 can move relative to the base 110 along the first direction X so that the charging interface 311 is exposed in the cover 120. The second limiting portion 121a cooperates with the first limiting portion 112a to restrict the movement of the cover 120 within its stroke in the first direction X. The first limiting portion 112a and the second limiting portion 121a can limit the relative movement between the cover 120 and the base 110 by increasing the damping between them. Specifically, the first limiting part 112a and the second limiting part 121a can increase the frictional force between the cover 120 and the base 110 by increasing the coefficient of friction between the base 110 and the cover 120. The first limiting part 112a and the second limiting part 121a can also increase the frictional force between the cover 120 and the base 110 by increasing the interaction force between them. The first limiting part 112a and the second limiting part 121a can further restrict the relative movement between the cover 120 and the base 110 by adding locking points within their stroke.

[0118] In the technical solution of this application, the cover 120 is connected to the base 110, and the cover 120 is movable relative to the base 110. The movement states of the cover 120 include an open movement state moving away from the base along a first direction X, and a closed movement state moving towards the base in the opposite direction of the first direction X. The base 110 has a first limiting part 112a, and the cover 120 has a second limiting part 121a. The first limiting part 112a and the second limiting part 121a cooperate with each other to limit the movement of the cover 120 relative to the base 110. Due to the provision of the first limiting part 112a and the second limiting part 121a, the cover 120 can stop at any position within the formation, and the user can switch between the open and closed states at any time within the formation. Thanks to the protection of the first limiting part 112a and the second limiting part 121a, the internal vibration of the cover assembly 100 is small when the cover 120 switches states, the risk of damage to the cover 120 is greatly reduced, and the service life of the cover assembly 100 is greatly extended. Furthermore, the first limiting part 112a and the second limiting part 121a make the cover 120 more stable when opening or closing, preventing accidental pop-out or incomplete closure due to the cover 120 opening too quickly or too slowly, and reducing accidental operation. The way the first limiting part 112a and the second limiting part 121a restrict the movement of the cover 120 can be set according to different usage requirements. As shown in Figures 22 and 23, in some embodiments, the first limiting part 112a and the second limiting part 121a can be configured as structures that can interact magnetically with each other, so as to restrict the movement of the cover 120 by the action of a magnetic field. The first limiting part 112a and the second limiting part 121a can increase the force perpendicular to the first direction X between the cover 120 and the base 110 through the mutual attraction of the magnetic field, thereby restricting the movement of the cover 120. In some embodiments, the first limiting part 112a is configured as a magnet, and the second limiting part is configured as a material that responds to a magnetic field. In some embodiments, the first limiting portion 112a is configured as a material responsive to a magnetic field, and the second limiting portion 121a is configured as a magnet. Specifically, the magnet can be an electromagnet or a permanent magnet. The material responsive to a magnetic field can be iron, nickel, cobalt, and their alloys and compounds. The material responsive to a magnetic field can be a hard magnetic material, a soft magnetic material, or a rectangular magnetic material, as long as the first limiting portion 112a and the second limiting portion 121a can jointly restrict the movement of the cover 120 relative to the base and reduce the impact force between the cover 120 and the base 110. In some embodiments, both the first limiting portion 112a and the second limiting portion 121a are configured as magnets, wherein the magnetic polarity of the side of the first limiting portion 112a closer to the second limiting portion 121a is opposite to the magnetic polarity of the side of the second limiting portion 121a closer to the first limiting portion 112a.Specifically, if the magnet of the first limiting part 112a has a north pole on the side closer to the second limiting part 121a, then the magnet of the second limiting part 121a has a south pole on the side closer to the first limiting part 112a. Conversely, the magnet of the first limiting part 112a can have a south pole on the side closer to the second limiting part 121a, and a north pole on the side closer to the first limiting part 112a. Thanks to the application of the magnet, the sliding damping effect between the cap 120 and the base 110 is significantly improved. The damping force generated by the magnetic field helps control the speed of the cap 120 when opening and closing, reducing unnecessary vibration and noise, thereby stabilizing the system's movement and preventing system failure or performance degradation due to excessive vibration. The interaction between the magnet and the magnetic material can precisely control the opening and closing stroke of the pen cap, improving the accuracy and stability during use and preventing accidental opening or closing of the pen cap.

[0119] In different embodiments, the positions of the first limiting part 112a and the second limiting part 121a may vary depending on the arrangement of the cover 120 and the base 110. As shown in Figures 21 and 22, in some embodiments, the base 110 further includes a rod 113 and a bracket 114a. The bracket 114a is connected to the rod 113, and the third direction Y intersects with the first direction X. The bracket 114a defines a connection port 1141 with its opening facing the third direction Y. A connecting part 111 is provided at the connection port 1141. The first limiting part 112a is connected to the end of the bracket 114a away from the rod 113. The second limiting part 121a extends along the first direction X and passes through the fourth receiving cavity 122a. That is, the connecting part 111 is connected to the bracket 114a, and the connecting part 111 is provided on the side of the first limiting part 112a near the rod 113. Optionally, the third direction Y can be perpendicular to the first direction X. That is, the connection port 1141 is located on the side of the bracket 114a, and the cover 120 can expose the charging interface 311 without completely detaching from the base, thereby avoiding the separation of the cover 120 from the base 110, improving the ease of use of the cover 120, and greatly reducing the possibility of losing the cover 120. The first limiting part 112a is located at the end of the bracket 114a. When the cover 120 is fastened to the base 110, the first limiting part 112a is also located in the fourth receiving cavity 122a. Since the second limiting part 121a passes through the fourth receiving cavity 122a, the first limiting part 112a and the second limiting part 121a can be stably in contact during the movement of the cover 120. Optionally, the second limiting part 121a can extend out and be exposed in the fourth receiving cavity 122a. When the cover 120 is fastened to the base, the second limiting part 121a can be inserted into the base 110 to enhance the connection stability between the base 110 and the cover 120.

[0120] In different embodiments, the number of components in the first limiting portion 112a and the second limiting portion 121a may vary. As shown in Figures 22 and 23, in some embodiments, the first limiting portion 112a includes a first limiting member 1121a and a second limiting member 1122, the second direction Z intersects the first direction X, and the first limiting member 1121a and the second limiting member 1122 are disposed opposite each other along the second direction Z. The second limiting portion 121a includes a first sensing member 1211 and a second sensing member 1212 disposed opposite each other along the second direction Z. The second limiting portion 121a is sleeved on the bracket 114a so that the first limiting member 1121a senses the first sensing member 1211, and the second limiting member 1122 senses the second sensing member 1212. The second direction Z may be perpendicular to the first direction X, or optionally, the second direction Z may be perpendicular to the first direction X and a third direction Y. The first sensing member 1211 may be integrally formed on the second sensing member 1212. The first limiting part 112a and the second limiting part 121a can each be configured as multiple one-to-one corresponding sensing components to further improve the movement stability of the cover 120.

[0121] Due to the properties of magnets, the first limiting part 112a and the second limiting part 121a do not need to be in direct contact, but the magnetic force between them can still restrict the movement of the cover 120. As shown in Figures 22 and 23, in some embodiments, the end of the bracket 114a away from the rod 113 defines a fifth receiving cavity 1142, and the first limiting part 112a is disposed in the fifth receiving cavity 1142, so that the first limiting part 112a and the second limiting part 121a are spaced apart. The spaced arrangement of the first limiting part 112a and the second limiting part 121a makes the connection surface between the cover 120 and the base 110 smoother, reduces mechanical wear between the cover 120 and the base, and improves the service life of the cover 120.

[0122] To further improve the connection stability when the cover 120 is closed onto the base 110, as shown in Figures 23 and 24, in some embodiments, the cover 120 further includes a third limiting part 123a. The third limiting part 123a is disposed in the receiving cavity. When the cover 120 moves in the opposite direction of the first direction X to engage with the base 110, the first limiting part 112a can attract the third limiting part 123a. Specifically, the third limiting part 123a can be connected to the second limiting part 121a or to the outer shell 122 of the cover 120, as long as the third limiting part 123a can attract the first limiting part 112a when the cover 120 is engaged with the base 110. Specifically, if the first limiting part 112a is configured as a magnet, the third limiting part 123a can be configured as a magnet that can attract it or other materials that can respond to a magnetic field. If the first limiting part 112a is configured as a material that can respond to a magnetic field, then the third limiting part 123a can be configured as a magnet, and there is no restriction here.

[0123] As shown in Figures 23 and 24, to further improve the protection of the power module 30 and reduce the risk of damage to the power module 30, the base 110 may also be provided with an inner housing 118. Accordingly, the inner housing 118 can extend into the receiving cavity to further improve the connection stability between the cover 120 and the base 110. In order to reduce the wear and tear of the cover 120, the inner housing 118 can be spaced apart from the second limiting part 121a. In some embodiments, the base 110 further includes the inner housing 118, which is sleeved on the bracket 114a. The cover 120 also includes an outer shell 122, with a second limiting portion 121a connected to the outer shell 122. The outer shell 122 defines a fourth receiving cavity 122a, through which the second limiting portion 121a passes, dividing the fourth receiving cavity 122a into an inner chamber 1221 and an outer chamber 1222. The outer chamber 1222 is located on the side of the second limiting portion 121a near the outer shell 122, and the inner chamber 1221 is located on the side of the second limiting portion 121a away from the outer shell 122. A bracket 114a can pass through the inner chamber 1221, and an inner shell 118 can pass through the outer chamber 1222. The inner shell 118 and the second limiting portion 121a are spaced apart along the first direction X and / or along a direction perpendicular to the first direction X. That is, an assembly gap is maintained between the inner shell 118 and the second limiting portion 121a. The outer shell 122 can abut against the inner shell 118, and the outer shell 122 can also abut against other shells of the base other than the inner shell 118, so as to improve the sealing performance of the outer shell 122. There are no restrictions here.

[0124] In some embodiments, the first limiting portion 112a and the second limiting portion 121a may also be provided with multiple locking points to restrict the relative movement of the cover 120 and the base 110, thereby increasing the damping during the relative movement of the cover 120 and the base 110. As shown in FIG25, in some embodiments, the first limiting portion 112a is configured as a third protrusion 1123, which is located at one end of the base 110 near the cover 120. The second limiting portion 121a is configured as a plurality of fourth protrusions 1213 spaced apart along the first direction X. The third protrusions 1123 can engage with the gaps between the fourth protrusions 1213 to restrict the movement of the cover 120. As shown in Figure 24, in some embodiments, the first limiting portion 112a is configured as a plurality of fifth protrusions 1124 spaced apart along the first direction X, and the second limiting portion 121a is configured as a sixth protrusion 1214. The sixth protrusion 1214 is located at one end of the cover 120 near the base 110, and can engage with the gap between the fifth protrusions 1124 to restrict the movement of the cover 120. It is understood that each protrusion can be integrally formed on the base or other connecting parts of the cover 120, and no limitation is made here. The arrangement of the fourth protrusion 1213 and the fifth protrusion 1124 allows the cover 120 to stop at any position within its stroke, and the groove between the protrusions spaced apart along the first direction X can also reduce the opening angle of the second limiting portion 121a perpendicular to the first direction X, reducing the risk of fatigue fracture of the second limiting portion 121a. It is understood that in some embodiments, the first limiting portion 112a may be configured with a plurality of protrusions spaced apart along the first direction X, and the second limiting portion 121a may also be configured with a plurality of protrusions spaced apart along the first direction X. The protrusions of the first limiting portion 112a are adapted to engage with the gaps between the protrusions of the second limiting portion 121a respectively. The arrangement of multiple protrusions can further reduce the risk of wear failure of the first limiting portion 112a and the second limiting portion 121a. It should be noted that in some embodiments, the cover assembly 100 may only have the third protrusion 1123 and the fifth protrusion 1124, or the first limiting portion 112a may be configured as a magnet to improve the movement stability of the cover 120 and reduce the risk of damage to the components of the cover assembly 100. In some embodiments, as shown in FIG24, the cover assembly 100 may also have the aforementioned protrusions and magnets at the same time, both of which together improve the movement stability of the cover 120, which will not be elaborated here.

[0125] To further improve the stability of the cover 120 moving along the first direction X and reduce the risk of the cover 120 detaching from the base 110, as shown in FIG25, in some embodiments, the base 110 has a second groove 116 extending along the first direction X, and the cover 120 has a seventh protrusion 125a, which passes through the second groove 116 to allow the cover 120 to slide along the groove. As shown in FIG24, in some embodiments, the cover 120 has a first groove 126 extending along the first direction X, and the base 110 has an eighth protrusion 117a, with a sixth protrusion passing through the first groove 126 to allow the cover 120 to slide along the groove. The second groove 116 and the first groove 126 are the guide grooves for the cover 120 to move along the first direction X. Taking the base 110 having a second groove 116 and the cover 120 having a seventh protrusion 125a as an example, the second groove 116 can be provided on the peripheral wall of the bracket 114a. When the base has a third protrusion 1123, the second slot 116 can be located on the side of the third protrusion 1123 near the cover 120, or on the side of the third protrusion 1123 away from the cover 120. When the first limiting part 112a of the base is disposed with the magnet, and the magnet is located at one end of the bracket 114a near the cover 120, the second slot 116 can be located at one end of the first limiting part 112a near the rod 113.

[0126] In some embodiments, as shown in FIG23, to improve the internal connection stability of the electronic pen 200, the circuit board inside the electronic pen 200 can be configured as a flexible printed circuit board 117. To facilitate user identification of the charging / discharging or data transmission status of the electronic pen 200 through the charging interface 311, in some embodiments, the substrate 110 further includes the flexible printed circuit board 117 and an indicator light (not shown in the figure). Along the first direction X, one end of the flexible printed circuit board is connected to the power module 30, and the other end is connected to the indicator light, which is used to display the working status of the charging interface 311. The indicator light can be located on the cover 120 or any suitable position such as the rod 113.

[0127] Fourth aspect

[0128] Referring to Figures 26, 27, and 30, the power module 30 further includes a charging module 40 connected to the module body 31. The charging module 40 has a charging interface 311 and is located on the side of the module body 31 away from the second connector 32. The first connector 20 includes a first connecting portion 201, and the second connector 32 includes a second connecting portion 321. The first connecting portion 201 and the second connecting portion 321 are detachably connected. In some embodiments, the pen body 10 contains a pen refill module 50 and a power module 40. The pen refill module 50, the module body 31, and the charging module 40 are electrically connected sequentially along the axial direction, specifically via contact connections. The pen refill module 50 and the power module 30 are connected and fixed together by the first connector 20 and the second connector 32.

[0129] Understandably, in some embodiments, the connection between the first connector 20 and the second connector 32 may include a mechanical connection or an electrical connection, wherein the first connection portion 201 and the second connection portion 321 are portions away from the pen refill module 50.

[0130] Optionally, the connection between the first connecting part 201 and the second connecting part 321 can be any one of the following: a rotary snap-fit ​​connection, a pluggable elastic snap-fit ​​connection, or a button-type snap-fit ​​connection.

[0131] Alternatively, the portions of the first connector 20 and the second connector 32 near the pen refill module 50 may be electrically connected, including one of the following: a pogo pin connector, a B to B connector, a terminal block connector, etc.

[0132] It should be noted that the Chinese name for pogo pin is spring pin, which is widely used in various electronic products and can be used for signal transmission and connection; B to B connector, also known as board to board connector, is a common connector product in the electronics market.

[0133] Optionally, referring to Figures 28 and 30, the first connecting part 201 and the second connecting part 321 are connected by a button-type snap-fit ​​connection. The button b3 in the button-type snap-fit ​​connection has a raised structure or a hidden structure. Specifically, the button-type snap-fit ​​structure includes a male buckle b1 on one of two adjacent connecting parts and a female buckle b2 on the other. The male buckle b1 and the female buckle b2 are snap-fit ​​connected. For example, the first connecting part 201 is provided with a female buckle b2, and the second connecting part 321 is provided with a male buckle b1. In some embodiments, the second connecting part 321 is provided with a pressing groove, and the male buckle b1 is located in the pressing groove. The male buckle b1 and the pressing groove are connected by a first elastic body b4. A button b3 is also integrally connected to the male buckle b1. The button b3 protrudes from the pressing groove to form a raised structure, or the button b3 is located in the pressing groove and forms a hidden structure. It should be noted that the concealed structure will not interfere with other structures. When pressing it, other needle-like objects are needed. Pressing button b3 can move the male buckle b1 into the pressing groove, thereby disengaging it from the female buckle b2 and completing the disassembly.

[0134] Furthermore, referring to Figures 31 and 32, the rotating buckle structure includes a first rotating cavity b5 on one of two adjacent connectors and a second rotating cavity b6 on the other. The first rotating cavity b5 and the second rotating cavity b6 are rotatably engaged. One of the first rotating cavity b5 and the second rotating cavity b6 is provided with a slot b7, and the other is provided with a latch b8. After being rotated into position, the latch b8 engages with the slot b7. This can be indicated by touch and sound.

[0135] Furthermore, referring to Figures 29 and 30, the pluggable elastic buckle structure includes a second elastic body b9 disposed on one of two adjacent connectors and a snap-fit ​​hole b11 on the other. The second elastic body b9 is provided with a snap-fit ​​body b10, which may be a ball. The snap-fit ​​body b10 and the snap-fit ​​hole b11 are snapped together by the elastic force provided by the second elastic body b9. Specifically, the second elastic body b9 and the aforementioned first elastic body b4 include, but are not limited to, objects with elastic recovery such as plastic, spring, and foam.

[0136] It should be noted that the above fixing methods are secure and easy to disassemble. In addition, silicone rings can be added to prevent loosening caused by wear and tear, and to increase the number of times the device can be disassembled and used.

[0137] Optionally, the power module 30 is movably disposed axially with respect to the pen body 10, and the power module 30 can be pulled out to the outside of the receiving cavity 11 to facilitate battery removal.

[0138] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0139] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0140] Of course, the above are only some optional embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the concept of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
