[0035] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION
[0036] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.
[0037] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.
[0038] In the description of the present application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.
[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0040] The electronic pen comprises a pen barrel, a refill module and a pen eraser module, both of which are installed in the pen barrel, the refill module is located at one end of the pen barrel, and the pen eraser module is located at the other end of the pen barrel, and the user can hold the pen barrel to move the electronic pen.
[0041] The electronic pen is used in conjunction with an electronic device. When the refill module faces the electronic device, the electronic pen can be moved to write and draw on the display screen of the electronic device; when the eraser module faces the electronic device, the text and pictures on the display screen of the electronic device can be erased by moving the electronic pen. In this way, paperless handwriting can be achieved, which is beneficial to environmental protection.
[0042] For example, the electronic pen can be an electromagnetic pressure-sensitive stylus, the electronic pen can use a capacitive pressure-sensitive chip, the electronic pen can include a pen tip that abuts against the capacitive pressure-sensitive chip, and the pen tip has a very short movement stroke, which is almost negligible, optimizing the writing experience for students who have obsessive-compulsive handwriting habits. In addition, the electronic pen can support suspension sensing, making it easier to confirm the position of the electronic pen, and the volume of the refill module can also be reduced to avoid blocking the screen, and to more clearly distinguish between fingers and electronic pens, thereby preventing accidental touches. The electronic device can be a tablet or smart phone with a built-in electromagnetic film. The pressure-sensitive data is transmitted between the electronic pen 1 and the electronic device through a digital protocol, and the data has high accuracy and good stability.
[0043] Of course, those skilled in the art will appreciate that the electronic pen may also be other types of electronic pens, such as a capacitive stylus pen.
[0044] When the electronic pen in the prior art is dropped or bumped, the pen barrel and the pen tip will transfer force to the pen core module, and the force on the pen core module cannot be effectively transferred outward, causing the pen core module to be easily damaged.
[0045] The electronic pen 1 of the embodiment of the present application, by adding a buffer member 400 in the pen barrel 100, and arranging the buffer member 400 between the pen core module 200 and the wiping member 310 of the eraser module 300, the buffer member 400 is used to buffer the force between the pen core module 200 and the wiping member 310, and can effectively absorb the force transmitted from the pen core module 200 to the direction of the wiping member 310 when the electronic pen 1 falls or bumps, thereby reducing the force on the pen core module 200 and reducing the probability of damage to the pen core module 200.
[0046] The electronic pen 1 according to an embodiment of the present application is described below with reference to the accompanying drawings.
[0047] See also Figures 1 to 6 The electronic pen 1 of the embodiment of the present application includes a pen barrel 100 , a pen core module 200 , a pen eraser module 300 and a buffer member 400 .
[0048] The refill module 200 is movably disposed on the pen barrel 100 , and the refill module 200 is used to provide a writing function. The eraser module 300 is disposed on the pen barrel 100 , and the eraser module 300 is used to provide an wiping function, and the eraser module 300 includes a wiping member 310 .
[0049] The buffer 400 is disposed in the pen barrel 100 , and the buffer 400 can be disposed inside the pen barrel 100 , or a part of the buffer 400 is disposed outside the pen barrel, and another part of the buffer 400 is disposed inside the pen barrel. The buffer 400 is used to buffer the force of the pen core module 200 along the axial direction of the electronic pen 1 .
[0050] In some embodiments of the present application, the buffer 400 is located between the refill module 200 and the wiper 310, and the buffer 400 is used to buffer the force between the refill module 200 and the wiper 310, for example, the buffer 400 is used to buffer the force when the refill module 200 and the wiper 310 are close to each other.
[0051] In other embodiments of the present application, the buffer 400 can be fixedly connected to the pen barrel 100. When the refill module 300 moves toward the inside of the pen barrel 100, the refill module 300 and the buffer 400 stop each other. The buffer 400 can buffer the axial force of the refill module 300 on the electronic pen 1.
[0052] It should be noted that the wiper 310 is a device that can interact with the electronic device to wipe the text and pictures on the screen of the electronic device. For example, when the electronic pen 1 is an electromagnetic pressure-sensitive stylus pen, and the electronic device is a tablet computer or a smart phone with a built-in electromagnetic film, the wiper 310 can be an induction magnet.
[0053] According to the electronic pen 1 of the embodiment of the present application, by arranging the refill module 200 and the eraser module 300 on the pen barrel 100, multiple functions such as writing, drawing, and erasing can be realized. In addition, since the refill module 200 can move relative to the pen barrel 100, when the electronic pen 1 falls or collides, there will be no rigid force transmission between the refill module 200 and the pen barrel 100, and the part of the refill module 200 that contacts the pen barrel 100 will not be damaged.
[0054] If the refill module 200 moves toward the eraser module 300, the force transmitted from the refill module 200 to the wiper 310 will pass through the buffer 400. The buffer 400 can be an elastic member, such as a rubber member, a silicone member, and a spring. The buffer 400 can be elastically deformed under the force at this time, and the kinetic energy is converted into elastic potential energy and thermal energy. Therefore, a part of the kinetic energy will be consumed, reducing the impact force on the refill module 200, thereby achieving the purpose of buffering the force when the refill module 200 and the wiper 310 are close to each other, so as to reduce the probability of damage to the refill module 200.
[0055] If the wiping piece 310 moves toward the refill module 200, the force transmitted by the wiping piece 310 to the refill module 200 will also pass through the buffer 400. The buffer 400 can be elastically deformed under the force at this time, and the kinetic energy is converted into elastic potential energy and thermal energy. Therefore, part of the kinetic energy will be consumed, reducing the impact force on the refill module 200, thereby achieving the purpose of buffering the force when the refill module 200 and the wiping piece 310 approach each other, so as to reduce the probability of damage to the refill module 200.
[0056] Therefore, the electronic pen 1 according to the embodiment of the present application can reduce the impact force borne by the refill module 200 and reduce the probability of damage to the refill module 200 by providing the buffer member 400 .
[0057] like Figure 2-Figure 6 As shown, the eraser module 300 further includes an wiping control member 320 . The wiping control member 320 is disposed in the pen barrel 100 , and is electrically connected to the wiping member 310 . The wiping control member 320 is located between the refill module 200 and the wiping member 310 .
[0058] It should be noted that the wiping control member 320 can be a circuit board, and the wiping control member 320 and the wiping member 310 can be connected by a wire, or can be wirelessly connected, and the wiping control member 320 can control whether the wiping member 310 wipes the content on the display screen of the electronic device. For example, when the wiping member 310 is an induction magnet, the wiping control member 320 can control whether the wiping member 310 generates an induction magnetic field.
[0059] The buffer member 400 is disposed between the refill module 200 and the wiping control member 320 , and / or the buffer member 400 is disposed between the wiping member 310 and the wiping control member 320 .
[0060] That is to say, the buffer member 400 can be arranged between the refill module 200 and the wiping control member 320, or the buffer member 400 can be arranged between the wiping member 310 and the wiping control member 320, or one buffer member 400 is arranged between the refill module 200 and the wiping control member 320, and the other buffer member 400 is arranged between the wiping member 310 and the wiping control member 320.
[0061] By setting the wiping control member 320, it is possible to control whether the wiping member 310 generates the wiping function, thereby avoiding the occurrence of accidental wiping, and making the wiping more controllable. In addition, the arrangement of the buffer member 400, the refill module 200, the wiping control member 320 and the wiping member 310 is more diverse, and the arrangement of the buffer member 400, the refill module 200, the wiping control member 320 and the wiping member 310 can be adjusted according to the type, size and selection of each component of the electronic pen 1, so as to meet the structural requirements of different scenes and different functions, and the applicability of the electronic pen 1 is stronger.
[0062] like Figure 2-Figure 3 As shown, when the buffer member 400 is disposed between the wiping member 310 and the wiping control member 320 , one of the buffer member 400 and the wiping member 310 is provided with a first plug hole 410 and the other is provided with a first plug portion 311 , and the first plug portion 311 is plugged and matched with the first plug hole 410 .
[0063] Specifically, the first plug hole 410 is provided on the side of the buffer 400 facing the wiping control member 320, and the first plug portion 311 is provided on the side of the buffer 400 facing the buffer 400. In this way, the relative position between the buffer 400 and the wiping member 310 in the radial direction of the pen barrel 100 can be limited, and relative deflection between the buffer 400 and the wiping member 310 in the radial direction of the pen barrel 100 can be avoided.
[0064] like Figure 2-Figure 3As shown, the cross-section of the first plug hole 410 and the cross-section of the first plug part 311 are configured as non-circular shapes that match. For example, the cross-section of the first plug hole 410 can be configured as an ellipse, an oblong, or a polygon, and the cross-section of the first plug part 311 can be configured as an ellipse, an oblong, or a polygon that matches the first plug hole 410.
[0065] In this way, relative rotation between the buffer member 400 and the wiper member 310 can be avoided, thereby ensuring the position stability of the buffer member 400 and the wiper member 310 in the pen holder 100 .
[0066] like Figure 2-Figure 3 As shown, the first plug hole 410 is provided on the buffer 400 , and includes a thick section 411 and a thin section 412 . The thick section 411 is located on the side of the thin section 412 facing the wiper 310 , and the cross-sectional area of the thick section 411 is greater than the cross-sectional area of the thin section 412 .
[0067] The first plug-in portion 311 is disposed on the wiping member 310 , the cross-sectional area of the first plug-in portion 311 is smaller than the cross-sectional area of the wiping member 310 , at least a portion of the first plug-in portion 311 is inserted in the thin section 412 , and a portion of the wiping member 310 is inserted in the thick section 411 .
[0068] In this way, the matching size and matching area between the buffer 400 and the wiper 310 are larger, which is conducive to ensuring the reliability of the relative position between the buffer 400 and the wiper 310. In addition, the size of the buffer 400 can be increased, but the size of the buffer 400 and the wiper 310 in the length direction of the pen barrel 100 will not be increased. Under the condition of increasing the upper limit of the absorbed energy of the buffer 400, the miniaturization of the electronic pen 1 is guaranteed, and the space utilization rate in the pen barrel 100 is improved.
[0069] like Figure 2-Figure 3 As shown, one of the buffer member 400 and the wiping control member 320 is provided with a second plug hole 420 and the other is provided with a second plug portion 321 , and the second plug portion 321 is plugged and matched with the second plug hole 420 .
[0070] Specifically, the second plug portion 321 is provided on the side of the wiping control member 320 facing the buffer member 400, and the second plug hole 420 is provided on the side of the buffer member 400 facing the wiping control member 320. In this way, the relative position between the buffer member 400 and the wiping control member 320 in the radial direction of the pen barrel 100 can be limited, and relative deflection between the buffer member 400 and the wiping control member 320 in the radial direction of the pen barrel 100 can be avoided.
[0071] like Figure 2-Figure 6As shown, the electronic pen 1 further includes a counterweight 500. The counterweight 500 is disposed in the pen barrel 100, wherein the counterweight 500 may be an object with a relatively high density, such as metal iron. By setting the weight of the counterweight 500, the weight of the electronic pen 1 can be adjusted, the feel of the electronic pen 1 can be increased, and the holding experience can be optimized. Furthermore, the counterweight 500 is located between the refill module 200 and the wiper control member 320. During the use of the electronic pen 1, whether the refill module 200 is facing the electronic device or the wiper module 300 is facing the electronic device, the counterweight 500 is approximately located in the middle of the length direction of the pen barrel 100, thereby avoiding an imbalance in weight at both ends of the length direction of the pen barrel 100 and ensuring the comfort of holding the electronic pen 1.
[0072] When the buffer member 400 is disposed between the refill module 200 and the wiping control member 320 , the buffer member 400 is disposed between the refill module 200 and the counterweight 500 , and / or the buffer member 400 is disposed between the counterweight 500 and the wiping control member 320 .
[0073] That is to say, the buffer 400 is arranged between the refill module 200 and the counterweight 500, or the buffer 400 is arranged between the counterweight 500 and the wiping control member 320, or one buffer 400 is arranged between the refill module 200 and the counterweight 500, and the other buffer 400 is arranged between the counterweight 500 and the wiping control member 320.
[0074] When the buffer 400 is arranged between the refill module 200 and the counterweight 500, when the electronic pen 1 falls, the force received by the refill module 200 is first transmitted to the buffer 400, and then transmitted to the counterweight 500 and the eraser module 300. At this time, the counterweight 500 can be fixed in relative position with the pen barrel 100, or the counterweight 500 can be movable relative to the pen barrel 100; when the buffer 400 is arranged between the wiping control component 320 and the counterweight 500, when the electronic pen 1 falls, the force received by the refill module 200 is first transmitted to the counterweight 500, and then transmitted to the buffer 400 through the counterweight 500, and finally the buffer 400 transmits the force to the wiping control component 320. At this time, the counterweight 500 is movable relative to the pen barrel 100, and the wiping control component 320 can be fixed in relative position with the pen barrel 100, or the wiping control component 320 can be movable relative to the pen barrel 100.
[0075] In this way, the arrangement of the buffer 400, the refill module 200, the wiping control component 320 and the refill module 200 is more diverse. The arrangement of the buffer 400, the refill module 200, the wiping control component 320 and the refill module 200 can be adjusted according to the type, size and selection of each component of the electronic pen 1, so as to meet the structural requirements of different scenes and different functions, and the applicability of the electronic pen 1 is stronger.
[0076] like Figure 2-Figure 3 As shown, one of the counterweight block 500 and the refill module 200 is provided with a third plug hole 210 and the other is provided with a third plug portion 510 , and the third plug portion 510 is plugged and matched with the third plug hole 210 .
[0077] For example, the third plug-in portion 510 can be arranged on the side of the counterweight block 500 facing the refill module 200, the third plug-in portion 510 can be a column, the third plug-in hole 210 can be arranged on the side of the refill module 200 facing the counterweight block 500, the third plug-in hole 210 can be circular, and the third plug-in portion 510 and the third plug-in hole 210 do not need to consider the angle between each other when plugging together, so the plug-in is more convenient.
[0078] In this way, the counterweight block 500 and the refill module 200 can be positioned in the radial direction of the pen barrel 100 , thereby preventing the counterweight block 500 and the refill module 200 from being relatively misaligned in the radial direction of the pen barrel 100 .
[0079] like Figure 5-Figure 6 As shown, the counterweight 500 is provided with an extension portion 520 , which is located at one end of the counterweight 500 facing away from the refill module 200 , and the end of the extension portion 520 facing away from the refill module 200 is located between the opposite ends of the wiping control member 320 .
[0080] In this way, the extension portion 520 and the wiping control member 320 have an overlapping portion in the length direction of the pen barrel 100 , which can shorten the overall size of the counterweight block 500 and the wiping control member 320 in the length direction of the pen barrel 100 , thereby reducing the length of the electronic pen 1 .
[0081] In addition, by adding the extension part 520 , on the one hand, the volume of the counterweight block 500 can be increased, which is beneficial to adjust the weight of the electronic pen 1 , and the uniformity of the weight distribution of the electronic pen 1 is increased, thereby avoiding weight concentration that causes a decrease in the grip comfort of the electronic pen 1 .

[0082] In addition, the opposing surfaces of the extension portion 520 and the wiping control member 320 in the radial direction of the pen barrel 100 can be set as planes, so as to limit the relative positions of the extension portion 520 and the wiping control member 320 in the circumferential direction of the pen barrel 100, avoid relative rotation of the counterweight block 500 and the wiping control member 320 in the circumferential direction of the pen barrel 100, and make the structure of the electronic pen 1 more stable.
[0083] like Figure 1 , Figure 5-Figure 6 As shown, the electronic pen 1 further includes a pen tip 700 , the pen core module 200 is disposed in the pen barrel 100 , the pen tip 700 is connected to the pen core module 200 and the other end is located outside the pen barrel 100 .
[0084] For example, the pen tip 700 can be inserted into the refill module 200, and the pen tip 700 can move relative to the pen barrel 100 and the refill module 200. One end of the pen tip 700 located in the pen barrel 100 is used to contact the screen of the electronic device. This conforms to the writing and drawing habits of most users, and can reduce the force applied by the user when writing and drawing, providing a better user experience.
[0085] In addition, the refill module 200 is completely covered by the pen barrel 100, which reduces the probability of the refill module 200 being directly hit, and the probability of damage to the refill module 200 is also reduced. A portion of the nib 700 is also covered by the pen barrel 100, which reduces the probability of the nib 700 being directly hit, and the probability of damage to the nib 700 is also reduced.
[0086] like Figure 1-Figure 4 As shown, the pen holder 100 includes a first barrel 110 , a second barrel 120 and a decorative ring 130 .
[0087] The refill module 200 is disposed on the first barrel 110, one end of the second barrel 120 is connected to the first barrel 110, and the second barrel 120 and the first barrel 110 can be threadedly connected to facilitate assembly and disassembly, and at least a portion of the eraser module 300 is disposed on the second barrel 120. An installation groove is disposed on the outer surface of the second barrel 120, and the decorative ring 130 is disposed in the installation groove and contacts the first barrel 110.
[0088] For example, the outer circumference of the decorative ring 130, the outer circumference of the second barrel 120 and the outer circumference of the first barrel 110 may be located on the same curved surface. In addition, the first barrel 110 and the second barrel 120 may be plastic parts.
[0089] The decoration ring 130 improves the appearance and recognition of the electronic pen 1. In addition, since the first barrel 110 and the second barrel 120 are detachable, it is convenient to assemble and replace the refill module 200, the weight block 500 and the eraser module 300 in the pen barrel 100.
[0090] like Figure 2 As shown, one of the inner circumference of the decorative ring 130 and the outer circumference of the second barrel 120 is provided with a convex point 140, and the other of the inner circumference of the decorative ring 130 and the outer circumference of the second barrel 120 is in contact with the convex point 140. There can be a plurality of convex points 140, and the plurality of convex points 140 are arranged at intervals along the circumference of the pen holder 100. By providing the convex points 140, the decorative ring 130 and the second barrel 120 are in point contact, so as to reduce the friction between the decorative ring 130 and the second barrel 120, avoid assembly interference and over-tight assembly, and facilitate the disassembly and assembly between the decorative ring 130 and the second barrel 120.
[0091] like Figure 2-Figure 5as well as Figure 7 As shown, the pen holder 100 further includes a pen clip 150 . The pen clip 150 is connected to the other end of the second barrel 120 . A notch 121 is provided on the peripheral wall of the second barrel 120 . The pen clip 150 is provided with a positioning portion 151 , and the positioning portion 151 is located in the notch 121 .
[0092] For example, the pen clip 150 can be a plastic part. By setting the pen clip 150, the electronic pen 1 can be fixed on a structure such as a clothing pocket or a protective shell of an electronic device, so that the electronic pen 1 is easy to store and is not easy to fall or lose.
[0093] One of the side walls of the positioning portion 151 and the notch 121 is provided with a positioning groove 152 and the other is provided with a positioning protrusion 122 , and the positioning protrusion 122 fits in the positioning groove 152 .
[0094] In this way, the cooperation between the positioning groove 152 and the positioning protrusion 122 can achieve pre-positioning between the pen clip 150 and the second barrel 120. The structure is simple and easy to install. It does not require auxiliary products such as glue to fix it, which saves costs and improves production efficiency.
[0095] Specifically, the positioning portion 151 may be provided with grooves 123 on both sides of the pen holder 100 in the circumferential direction, the side walls of the notch 121 are inserted into the grooves 123 , and the positioning protrusions 122 are provided at the bottom of the grooves 123 .

[0097] For example, the flexible eraser 600 may be made of a soft rubber material, such as TPU (Thermoplastic polyurethane) soft rubber. The flexible eraser 600 is used to contact the screen of the electronic device, which conforms to the wiping habits of most users and can reduce the force applied by the user when wiping, providing a better user experience.
[0098] In addition, since the electronic pen 1 needs to be rubbed repeatedly on the screen during the wiping process, the flexible pen eraser 600 is configured as a flexible structure to avoid damage to the screen.
[0099] The outer circumference of the mounting protrusion 153 is provided with an annular groove 154, and the inner circumference of the flexible pen eraser 600 is provided with an annular rib 610, which is plugged into the annular groove 154, and the flexible pen eraser 600 covers the end of the mounting protrusion 153 that faces away from the second cylinder 120. In this way, it is convenient to install the flexible pen eraser 600 on the mounting protrusion 153, and to remove the flexible pen eraser 600 from the mounting protrusion 153. The flexible pen eraser 600 is a consumable part, and the detachable setting makes it easy to replace the flexible pen eraser 600.
