Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0039] like Figures 1 to 6 As shown, this embodiment of the present invention provides an electronic pen, comprising:

[0040] Shell 1.

[0041] Erasing component 2 is connected to the end of housing 1.

[0042] The erasing assembly 2 includes a mounting bracket 21, an elastic movable part 22, and an elastic sheet 23. The elastic movable part 22 is at least partially mounted on the outer wall of the mounting bracket 21, and the elastic sheet 23 is embedded inside the elastic movable part 22.

[0043] As can be seen from the above embodiments, in this application embodiment, since the erasing component 2 includes a mounting bracket 21, an elastic movable part 22 and an elastic sheet 23, the elastic movable part 22 is at least partially installed on the outer wall of the mounting bracket 21, and the elastic sheet 23 is embedded in the interior of the elastic movable part 22, the elastic sheet 23 increases the overall flexibility of the elastic movable part 22, so that the erasing component 2 has a larger deformation stroke when erasing, thereby improving the user experience of the electronic pen.

[0044] In the above embodiments, the housing 1 can be a cylindrical housing structure, a square housing structure, or a housing structure of other shapes; this application embodiment does not limit this. The axial end of the housing 1 can have an opening, which can be understood as the housing 1 being a cylindrical structure with an open tail end. It should be noted that, in this application embodiment, the axial direction of the housing 1 can be as follows... Figure 2 The direction indicated by X in the figure, the radial direction of housing 1 can be as follows: Figure 2 The direction indicated by Y in .

[0045] The erasing component 2 can be installed on the end of the housing 1 in the first direction by means of plugging, snapping, or socketing. In this embodiment, the erasing component 2 is mainly used to erase the writing trajectory information formed by the electronic pen. During use, the erasing component 2 transmits the writing trajectory information to be erased to the electronic pen. In normal use, since the erasing components commonly used to erase writing information, such as the text information written in pencil, are usually erased by an eraser, and since the eraser is an elastic element, it can be locally deformed during erasing, providing a certain erasing feel.

[0046] Based on this, in this embodiment, in addition to the elastic movable part 22 providing elastic deformation, the elastic sheet 23 can also provide elastic deformation. The elastic sheet 23 can be a component that is easily deformable, such as a steel sheet, aluminum sheet, or copper sheet, and can transmit electrical signals and act as an electrode; this embodiment does not limit its application in this regard. The elastic movable part 22 can be an elastic block structure, so that the elastic movable part 22 can have an elastic reset function, thereby allowing the elastic movable part 22 to return to its initial shape after the deformation is erased. The elastic movable part 22 can be an integral elastic structure or a split elastic structure; this embodiment does not limit its application in this regard.

[0047] In addition, the mounting bracket 21 has a frame structure, at least a part of the mounting bracket 21 is used to mount the elastic movable part 22, and the other part of the mounting bracket 21 is used to connect with the housing 1, so that the erasing assembly 2 can be connected to the end of the housing 1.

[0048] In some embodiments, the elastic movable part 22 includes a first elastic block 221 and a second elastic block 222. The first elastic block 221 includes a first fastening surface 2211, and the second elastic block 222 includes a second fastening surface 2221. The first fastening surface 2211 and the second fastening surface 222 are arranged opposite to each other along the radial direction of the housing 1, and the first fastening surface 2211 and the second fastening surface 2221 are fastened together by an elastic piece 23.

[0049] In this embodiment, since the elastic movable part 22 includes a first elastic block 221 and a second elastic block 222, the first elastic block 221 includes a first fastening surface 2211, and the second elastic block 222 includes a second fastening surface 2221. The first fastening surface 2211 and the second fastening surface 2221 are arranged opposite to each other along the radial direction of the housing 1. The first fastening surface 2211 and the second fastening surface 2221 are fastened by the elastic sheet 23. Therefore, the elastic sheet 23 can be located inside the first elastic block 221 and the second elastic block 222, that is, the elastic sheet 23 is located inside the elastic movable part 22. This allows the elastic sheet 23 to move or deform as a whole with the elastic movable part 22, further ensuring the increased deformation stroke of the elastic sheet 23 on the elastic movable part 22, thereby improving the erasing feel of the erasing component 2.

[0050] In some embodiments, the elastic sheet 23 is provided with a snap-fit ​​through hole 61, and snap-fit ​​protrusions 223 are provided on both the first snap-fit ​​surface 2211 and the second snap-fit ​​surface 2221, the snap-fit ​​protrusions 223 snapping into the snap-fit ​​through hole 61. And / or, a limiting frame structure 62 is formed at the end of the elastic sheet 23 away from the housing 1, the limiting frame structure 62 has a limiting cavity, the first snap-fit ​​surface 2211 is provided with a limiting protrusion 2212 protruding towards the second snap-fit ​​surface 2221, the limiting protrusion 2212 is embedded in the limiting cavity, the second snap-fit ​​surface 2221 is provided with a groove structure 2222, the limiting frame structure 62 is embedded in the groove structure 2222.

[0051] In this embodiment, since the elastic sheet 23 is provided with a snap-fit ​​through hole 61, and both the first snap-fit ​​surface 2211 and the second snap-fit ​​surface 2221 are provided with snap-fit ​​protrusions 223, which snap into the snap-fit ​​through hole 61, the first elastic block 221 and the second elastic block 222 can be assembled through the elastic sheet 23, which is more conducive to the assembly of the elastic movable part 22. In addition, since the end of the elastic sheet 23 away from the housing 1 forms a limiting frame structure 62, and the limiting frame structure 62 has a limiting cavity, the first snap-fit ​​surface 2211 is provided with a limiting protrusion 2212 protruding towards the second snap-fit ​​surface 2221, and the limiting protrusion 2212 is embedded in the limiting cavity, and the second snap-fit ​​surface 2221 is provided with a groove structure 2222, and the limiting frame structure 62 is embedded in the groove structure 2222, the first elastic block 22 can be lifted by snapping the limiting protrusion 2212 and the limiting cavity. The connection between the first elastic block 221 and the elastic sheet 23 is secure, and the relative position between the first elastic block 221 and the elastic sheet 23 can be limited by the engagement of the flexible limiting protrusion 2212 and the limiting cavity. The connection between the second elastic block 222 and the elastic sheet 23 is enhanced by the engagement between the limiting frame structure 62 and the groove structure 2222, and the relative position between the second elastic block 222 and the elastic sheet 23 can also be limited by the engagement between the limiting frame structure 62 and the groove structure 2222. It should be noted that the limiting frame structure 62 is a shell structure with cavities composed of multiple plate-like structures. This shell structure has a limiting cavity, and the shell structure can be embedded in the groove structure 2222. The elastic sheet 23 can be provided with at least one of the engaging through hole 231 and the limiting frame structure 232 to cooperate with the first engaging surface 2211 and the second engaging surface 2221.

[0052] In some embodiments, the electronic pen further includes a strain detection component 3, and the erasing component 2 is deformable relative to the housing 1 in the radial direction of the housing 1. The strain detection component 3 includes a strain detection element 31, a deformation plate 32, and a fixing bracket 33. The fixing bracket 33 is connected to the erasing component 2 and is used to mount the deformation plate 32. At least a portion of the strain detection element 31 is attached to the deformation plate 32. When the erasing component 2 deforms relative to the housing 1 in the radial direction of the housing 1, the strain detection element 31 is used to detect the deformation of the deformation plate 32.

[0053] In this embodiment of the application, in order to further improve the erasing feel of the erasing component 2, the structure of the strain detection component 3 can also be used to achieve this. The strain detection component 3 includes a strain detection element 31, a deformation plate 32 and a fixed bracket 33. The erasing component 2 has a change in stroke mainly through the structural deformation of the deformation plate 32, so as to achieve the above-mentioned effect.

[0054] Specifically, the strain detection element 31 in this embodiment can be a flexible circuit board, meaning the strain detection element 31 can undergo local deformation to increase the overall deformation of the erasure assembly 2. The strain detection element 31 can extend axially along the housing 1, with a portion fixed inside the housing 1 and the portion extending out of the housing 1 attached to the deformation plate 32 to collect deformation information. Furthermore, the deformation plate 32 is the main component for transmitting erasure information from the erasure assembly 2, i.e., it is the main component for sensing the movement trajectory of the erasure assembly 2. The deformation plate 32 can be a deformable signal transmission component such as a metal foil, semiconductor material, or polymer composite material; this embodiment does not limit its use. The fixing bracket 33 is mainly used to connect the erasure assembly 2 and the deformation plate 32, and can also be used to install and fix the strain detection element 31. The fixing bracket 33 can be a frame structure or a cylindrical structure, and its interior can have a deformation cavity to provide travel space for the subsequent deformation of the deformation plate 32.

[0055] Thus, in this embodiment, since at least a portion of the strain detection element 31 is attached to the deformation plate 32, when the erasing component 2 deforms relative to the housing 1 in the radial direction, the strain detection element 31 is used to detect the deformation of the deformation plate 32. Therefore, not only can the deformation information of the deformation plate 32 in the radial direction of the housing 1 be collected by the strain detection element 31, but the erasing component 2 can also deform in the second direction during erasing, thereby increasing the deformation stroke of the erasing component 2 and further improving the user experience of the electronic pen.

[0056] In some embodiments, the fixed bracket 33 includes a bracket body 331, a connecting seat 332, and an inner liner support 333. The bracket body 331 is detachably connected to the interior of the mounting bracket 21. The inner liner support 333 is disposed on the inner wall of the end of the housing 1. The end of the mounting bracket 21 is inserted into the inner liner support 333. The connecting seat 332 is connected to the interior of the bracket body 331 and is disposed opposite to the inner liner support 333 in the axial direction of the housing 1. One end of the deformation plate 32 in the axial direction of the housing 1 abuts against the inner liner support 333, and the other end of the deformation plate 32 in the axial direction of the housing 1 abuts against the connecting seat 332.

[0057] In this embodiment, the bracket body 331 can be a cylindrical structure or a frame structure. The bracket body 331 and the mounting bracket 21 can be detachably connected by means of snap-fit ​​or plug-in structures, thus facilitating assembly between them. For example, during installation, multiple snap-fit ​​protrusions and multiple snap-fit ​​grooves can be provided on the outer surface of the bracket body 331, allowing the snap-fit ​​protrusions to engage with the snap-fit ​​grooves, ensuring that both the bracket body 331 and the mounting bracket 21 are coaxially aligned along the axial direction of the housing 1. The connecting seat 332 can be a block structure, a cover structure, or other structures. The connecting seat 332 can be installed at the end of the bracket body 331 away from the housing 1 by snap-fit, nesting, or other means. The inner lining support 333 provides installation space for the mounting bracket 21. During installation, the inner lining support 333 can be first installed on the inner wall of the axial end of the housing 1, and then the axial end of the mounting bracket 21 can be inserted into the inner lining support 333. After that, the axial end of the deformation plate 32 abuts against the inner lining support 333, and the axial end of the deformation plate 32 abuts against the connecting seat 332. In this way, under the support of the connecting seat 332 and the inner lining support 333, the relative position of the deformation plate 32 in the axial direction of the housing 1 is fixed, which facilitates the deformation plate 32 to deform radially along the housing 1 under the action of external force.

[0058] Furthermore, regarding the fixing between the aforementioned connecting seat 332 and the deformation plate 32, in some embodiments, a limiting groove 3321 is provided on the end face of the connecting seat 332 facing the housing 1, a limiting protrusion 321 is provided at the end of the first end of the deformation plate 32, the limiting protrusion 321 is engaged in the limiting groove 3321, the inner liner support 333 is provided with a limiting plate facing the connecting seat 332, and the second end of the deformation plate 32 abuts against the limiting plate.

[0059] In this embodiment, since a limiting groove 3321 is provided on the end face of the connecting seat 332 facing the housing 1, and a limiting protrusion 321 is provided at the end of the first end of the deformation plate 32, the limiting protrusion 321 is engaged in the limiting groove 3321. Therefore, the connection between the first end of the deformation plate 32 and the connecting seat 332 is more stable through the engagement of the limiting protrusion 321 and the limiting groove 3321. Furthermore, since the inner liner support 333 is provided with a limiting plate facing the connecting seat 332, and the second end of the deformation plate 32 abuts against the limiting plate, the relative position of the deformation plate 32 in the axial direction of the housing 1 can be fixed under the combined action of the limiting plate and the connecting seat 332. It should be noted that in the above embodiment, a through hole structure can be opened in the middle of the limiting plate to facilitate the guidance of the strain detection element 31 into the deformation cavity.

[0060] In some embodiments, the strain detection element 31 further includes a first plate 312 and a signal transmission element 4. Both the elastic sheet 23 and the signal transmission element 4 extend along the axial direction of the housing 1. One end of the signal transmission element 4 is connected to the end of the elastic sheet 23 facing the housing 1, and the other end of the signal transmission element 4 is in contact with the first plate 312.

[0061] In this embodiment, the signal transmitting element 4 can be any of the deformable components that can transmit signals, such as a spring or a metal pin; this application does not limit this. Since both the elastic sheet 23 and the signal transmitting element 4 extend axially along the housing 1, one end of the signal transmitting element 4 is connected to the end of the elastic sheet 23 facing the housing 1, and the other end of the signal transmitting element 4 contacts the first plate 312. Therefore, the elastic sheet 23 can be used to switch between multiple functions of the electronic pen. Specifically, when the erasing component 2 generates an erasing motion, it drives the elastic sheet 23 to move synchronously, causing the elastic sheet 23 to deform the signal transmitting element 4, which then contacts the first plate 312 included in the strain detection element 31. This creates electrical continuity between the elastic sheet 23 and the first plate 312, thereby enabling rapid switching of the erasing function of the erasing component 2 and enhancing the functionality and user experience of the electronic pen. Simultaneously, because the elastic sheet 23 is elastic, it can increase the overall flexibility of the elastic moving part 22, allowing the erasing component 2 to have a larger deformation stroke during erasing. It should be noted that the plane on which the first plate 312 is located can intersect with the axial direction of the housing 1. In addition, since both the elastic sheet 23 and the signal transmission element 4 extend along the axial direction of the housing 1, the first plate 312 can provide a larger contact area for the signal transmission element 4.

[0062] It should be noted that, in the above embodiment, a mounting through hole extending in the first direction can be provided inside the end of the mounting bracket 21 facing the housing 1. The axis of the mounting through hole coincides with the axis of the mounting bracket 21 in the axial direction of the housing 1, and the axis of the mounting through hole coincides with the axis of the fixing bracket 33 in the axial direction of the housing 1. During installation, the elastic sheet 23 can be at least partially installed in the mounting through hole. In this way, through the above installation method, the elastic sheet 23, the signal transmission component 4, the erasing component 2, and the strain detection component 3 can form an integral structure.

[0063] In some embodiments, the strain detection element 31 further includes a second plate 311, the plane of which intersects the radial direction of the housing 1, and at least one surface of the second plate 311 is in contact with the deformation plate 32.

[0064] In this embodiment, since the strain detection element 31 also includes a second plate 311, the plane of the second plate 311 intersects the radial direction of the housing 1, and at least one surface of the second plate 311 is in contact with the deformation plate 32, it is convenient to provide sufficient contact area to the deformation plate 32 through the second plate 311, and it is convenient to adapt the second plate 311 to the deformation of the deformation plate 32 along the radial direction of the housing 1.

[0065] In some embodiments, the strain detection element 31 further includes a connecting plate 313, the second plate 311 and the first plate 312 are connected by the connecting plate 313, the fixed bracket 33 includes an embedded cavity 3323 inside, the fixed bracket 33 has an embedded through hole 3322 communicating with the embedded cavity 3323, the first plate 312 is located in the embedded cavity 3323, the connecting plate 313 passes through the embedded through hole 3322 and is connected to the first plate 312, and the end of the signal transmission element 4 facing the housing 1 extends into the embedded cavity 3323 and contacts the first plate 312.

[0066] In this embodiment, since the first plate 312 is located in the mounting cavity 3323, the connecting plate 313 passes through the mounting through hole 3322 and connects to the first plate 312. The end of the signal transmitting element 4 facing the housing 1 extends into the mounting cavity 3323 and contacts the first plate 312. Therefore, the first plate 312 and the second plate 311 can be isolated and installed through the fixing bracket 33. At the same time, the strain detection element 31 can be guided through the mounting through hole 3322, and the first plate 312 can be installed into the mounting cavity 3323 through the mounting through hole 3322. The signal transmitting element 4 can also be housed and installed through the mounting cavity 3323. It should be noted that the cavity 3323 can be a cavity structure formed inside the connecting seat 332 included in the fixed bracket 33, and the through hole 3322 can also be a through hole structure opened on the connecting seat 332. In this embodiment, the connecting seat 332 can be a cylindrical structure with one end open, and the open end of the connecting seat 332 faces away from the end of the shell 1.

[0067] In some embodiments, the end where the elastic sheet 23 and the signal transmitting member 4 are connected is a bent structure 233, and the bent structure 233 includes at least one bend that bends radially along the housing 1.

[0068] In this embodiment, since the end connecting the elastic sheet 23 and the signal transmitter 4 is a bent structure 233, and the bent structure 233 includes at least one bend along the radial direction of the housing 1, the connection between the elastic sheet 23 and the signal transmitter 4 can be a bent structure 233. The bend included in the bent structure 233 can further enhance the overall flexibility of the elastic sheet 23 and reduce the rigidity of the connection between the elastic sheet 23 and the signal transmitter 4. It should be noted that the bend included in the bent structure 233 can be a bent arc-shaped plate structure. Specifically, a bend can include a third plate and a fourth plate, with the third and fourth plates bent together, so that the bending angle between the third and fourth plates can change under the action of external force.

[0069] In some embodiments, the bracket body 331, the connecting seat 332, the inner liner support 333, and the mounting bracket 21 are all coaxially arranged along the axial direction of the housing 1.

[0070] In this embodiment, since the bracket body 331, connecting seat 332, inner liner support 333 and mounting bracket 21 are all coaxially arranged along the axial direction of the housing 1, the bracket body 331, connecting seat 332, inner liner support 333 and mounting bracket 21 can be installed as a whole by snap-fit ​​or nesting, which can facilitate the installation and disassembly of the electronic pen while ensuring the integrity of the electronic pen.

[0071] As can be seen from the above embodiments, in this application embodiment, since the erasing component 2 includes a mounting bracket 21, an elastic movable part 22 and an elastic sheet 23, the elastic movable part 22 is at least partially installed on the outer wall of the mounting bracket 21, and the elastic sheet 23 is embedded in the interior of the elastic movable part 22, the elastic sheet 23 increases the overall flexibility of the elastic movable part 22, so that the erasing component 2 has a larger deformation stroke when erasing, thereby improving the user experience of the electronic pen.

[0072] The various embodiments in the specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0073] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
