Detailed Implementation

[0019] 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.

[0020] 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.

[0021] Combined with reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5a to 5e ,in Figure 1 and Figure 2 The diagram shows the structure of the end of the electronic pen when the pen cap assembly 3 is in the second and first states, respectively. Figure 3 yes Figure 1 A sectional view along AA, Figure 4 yes Figure 2 A sectional view along BB. Figures 5a to 5e This is a cross-sectional view of the various components of the electronic pen, among which... Figure 5a This is a cross-sectional view of shell 1. Figure 5b This is a cross-sectional view of the telescopic component 2 when the pen cap component 3 is in the second state. Figure 3 A schematic diagram of the telescopic component 2. Figure 5c This is a cross-sectional view of the telescopic component 2 when the pen cap component 3 is in the first state, i.e. Figure 4 A schematic diagram of the telescopic component 2. Figure 5d This is a cross-sectional view of pen cap assembly 3. Figure 5e This is a cross-sectional view of the pressure detection component 4. This embodiment of the invention provides an electronic pen, comprising: a housing 1; a telescopic component 2 disposed inside the housing 1; a pen cap component 3, one end of which is connected to the telescopic component 2 to allow the pen cap component 3 to have a first state and a second state; the other end of the pen cap component 3 away from the telescopic component 2 is provided with a first mark 36 and a second mark 37, the first mark 36 and the second mark 37 having different morphologies; when the pen cap component 3 is in the first state, at least a portion of the second mark 37 is exposed in the housing 1; when the pen cap component 3 is in the second state, at least a portion of the first mark 36 and the second mark 37 are exposed in the housing 1; and a pressure detection component 4, which abuts against the end of the telescopic component 2 away from the pen cap component 3, to determine the function corresponding to the pen cap component 3 based on the pressure value detected by the pressure detection component 4 when the pen cap component 3 is in the first state or the second state.

[0022] In the above embodiments, the shell 1 can be a cylindrical shell 1 structure, a square shell 1 structure, or a shell 1 structure of other shapes. This utility model embodiment does not limit this. The shell 1 has an opening at the end in the extension direction X of the axis, which can be understood as a cylindrical structure with an open tail end.

[0023] The pen cap assembly 3 has a first state and a second state. In the first state and the second state, the pen cap assembly 3 extends into the housing 1 to different degrees. The pen cap assembly 3 can apply different pressures to the pressure detection assembly 4 through the telescopic assembly 2. That is, the pressure detection assembly 4 can detect different pressure values ​​when the pen cap assembly 3 is in the first state or the second state.

[0024] By acquiring the pressure value applied by the pen cap assembly 3 to the pressure detection assembly 4 via the telescopic assembly 2, the electronic pen can be customized with different functions. Based on the pressure value acquired by the pressure detection assembly 4, the function of the non-writing end of the electronic pen can be switched. For example, when the pressure value acquired by the pressure detection assembly 4 remains within a first pressure range, the erase function of the pen cap assembly 3 is activated; when the pressure value acquired by the pressure detection assembly 4 remains within a second pressure range that does not overlap with the first pressure range, the highlight function of the pen cap assembly 3 is activated. Furthermore, the function of the writing end of the electronic pen can also be switched based on the pressure value acquired by the pressure detection assembly 4. For example, when the pressure value acquired by the pressure detection assembly 4 remains within the first pressure range, the pen tip (not shown in the figure) performs the writing function; when the pressure value acquired by the pressure detection assembly 4 remains within the second pressure range, the pen tip performs the erase function (or highlight function). The above settings can enrich the functions of the electronic pen, simplify the process of switching electronic pen functions for users, and improve the user experience. The above-mentioned determination of different functions of the electronic pen based on pressure value can be implemented by the microcontroller unit (MCU) in the electronic pen, or the electronic pen can send the pressure value to the target device with which it interacts, and the target device can realize the different functions of the electronic pen.

[0025] Along the axial direction X of the housing 1, the surface of the pen cap assembly 3 is sequentially provided with a first mark 36 and a second mark 37. The first mark 36 and the second mark 37 can be configured to have different shapes, such as colors, patterns or textures. When the pen cap assembly 3 is in different states, the parts of the first mark 36 and the second mark 37 exposed outside the housing 1 are different, so as to remind the user of the current function of the pen cap assembly 3 or the pen tip.

[0026] For example, the pen cap assembly 3 is preset to perform the erasing function when the pressure value obtained by the pressure detection component 4 is in the first pressure range, at which time the pen cap assembly 3 is in the first state. The pen cap assembly 3 performs the highlighting function when the pressure value obtained by the pressure detection component 4 is in the second pressure range, at which time the pen cap assembly 3 is in the second state. The pen cap assembly 3 is provided with a yellow second mark 37 and a gray first mark 36 in sequence along the axial direction X of the housing 1. The gray first mark 36 is close to the telescopic component 2, while the yellow second mark 37 is far away from the telescopic component 2. When the pen cap assembly 3 is in the first state, the gray first mark 36 is completely covered by the housing 1, and the pen cap assembly 3 exposes at least part of the yellow second mark 37. When the pen cap assembly 3 is in the second state, the pen cap assembly 3 exposes at least part of the gray first mark 36 and the yellow second mark 37. Thus, when the user only observes the yellow second mark 37, it can be known that the pen cap assembly 3 is currently performing the erasing function. When the user observes both the yellow second mark 37 and at least part of the gray first mark 36, it can be known that the pen cap assembly 3 is currently performing the highlighting function. Alternatively, the pen cap assembly 3 can be preset to perform a highlight function when the pressure value obtained by the pressure detection component 4 is in the first pressure range, at which point the pen cap assembly 3 is in the first state. When the pressure value obtained by the pressure detection component 4 is in the second pressure range, the pen cap assembly 3 can perform an erasure function, at which point the pen cap assembly 3 is in the second state. The pen cap assembly 3 is provided with a yellow second mark 37 and a gray first mark 36 in sequence along the axial direction X of the housing 1. The gray first mark 36 is closer to the telescopic component 2, while the yellow second mark 37 is farther away from the telescopic component 2. When the pen cap assembly 3 is in the first state, the gray first mark 36 is completely covered by the housing 1, and the pen cap assembly 3 exposes at least part of the yellow second mark 37. When the pen cap assembly 3 is in the second state, the pen cap assembly 3 exposes at least part of the gray first mark 36 and the yellow second mark 37. Thus, when the user only observes the yellow second mark 37, it can be known that the pen cap assembly 3 is currently performing a highlight function. When the user observes both the yellow second mark 37 and at least part of the gray first mark 36, it can be known that the pen cap assembly 3 is currently performing an erasure function.

[0027] It should be noted that the pen cap assembly 3 can extend into the housing 1 so that the end of the pen cap assembly 3 extending along the axis X of the housing 1 is flush with the opening of the housing 1. That is, when the pen cap assembly 3 is in the first state, the end of the pen cap assembly 3 away from the telescopic component 2 can be flush with the opening of the housing 1. At this time, only the second mark 37 located on the end of the pen cap assembly 3 away from the telescopic component 2 is exposed at the opening of the housing 1. This part of the second mark 37 can be observed by the user, thereby determining the function currently performed by the electronic pen.

[0028] In this embodiment of the invention, the pen's end includes a housing, a cap assembly, a telescopic assembly, and a pressure detection assembly. Through the telescopic assembly, the cap assembly transmits different pressure values ​​to the pressure detection assembly in the pen in a first and a second state, respectively. The pressure detection assembly activates different functions of the cap assembly based on the acquired pressure values, thereby providing a wider range of functional options for the pen's end. The cap assembly includes a first mark and a second mark with different shapes. In the first or second state, the first and second marks are exposed outside the housing in different forms, allowing the user to determine the current function of the pen's cap assembly by observing the first mark and / or the second mark, thus improving the user experience.

[0029] Optional, in conjunction with reference Figure 5e , Figure 6 , Figure 7 and Figure 8 , Figure 6 An exploded view of the electronic pen provided by this utility model. Figure 7 This utility model provides an assembly structure diagram of an electronic pen including a pressure detection component 4. Figure 8 That is Figure 7 The exploded structural diagram of the pressure detection assembly 4 is shown. The pressure detection assembly 4 includes a detection element 41, a sensing element 42, and a first bracket 43. The sensing element 42 is connected to the housing 1 through the first bracket 43. The detection element 41 is attached to the sensing element 42. The sensing element 42 abuts against the end of the telescopic assembly 2 away from the pen cap assembly 3. The detection element 41 is used to obtain the pressure value of the sensing element 42 when the pen cap assembly 3 is in a first state or a second state.

[0030] The sensor 42 is the main component that responds to changes in the state of the pen cap assembly 3. The sensor 42 abuts against one end of the telescopic assembly 2, and the other end of the telescopic assembly 2 is connected to the pen cap assembly 3, so that the pressure applied by the pen cap assembly 3 to the telescopic assembly 2 can be transmitted to the sensor 42. The sensor 42 can be a deformable object such as a metal foil, semiconductor material, or polymer composite material. This embodiment of the utility model does not limit this.

[0031] In this embodiment of the present invention, the sensing element 42 is configured as a deformable element, and the detection element 41 is configured as a resistance strain gauge, the resistance value of which can change with the deformation of the sensing element 42; when the pen cap assembly 3 is in the first state and the second state, it will transmit different pressures to the sensing element 42 (including the case where the pressure value is 0, that is, the telescopic assembly 2 only contacts the sensing element 42, but does not squeeze, and the sensing element 42 is in the default state), causing the sensing element 42 to deform to different degrees. The detection element 41 can further obtain the pressure value applied to the sensing element 42 by the telescopic assembly 2 through the change of its own resistance value.

[0032] In some other embodiments of this invention not shown, the detection element 41 and the sensing element 42 can be configured as a capacitive pressure sensor, that is, the sensing element 42 constitutes one plate of a capacitor. When the pressure applied by the pen cap assembly 3 to the telescopic assembly 2 is transmitted to the sensing element 42, the distance between the sensing element 42 and the other plate in the capacitor changes, thereby changing the capacitance value of the capacitor. The detection element 41 can further obtain the pressure value applied by the telescopic assembly 2 to the sensing element 42 by detecting the capacitance value of the capacitor.

[0033] Optional, in conjunction with reference Figure 6 , Figure 7 and Figure 8 The sensing element 42 includes a strain plate 421 and an assembly 422 disposed on the side of the strain plate 421. The strain plate 421 is provided with a protrusion 4211, which is used to abut against the end of the telescopic assembly 2 away from the pen cap assembly 3. At least a portion of the strain plate 421 is attached with a detection element 41. The inner wall of the first bracket 43 is provided with an assembly groove 433. The assembly 422 is used to snap the strain plate 421 into the assembly groove 433.

[0034] The sensor 42 and the housing 1 can be connected via a first bracket 43, which can also be used to mount and fix the telescopic assembly 2. The first bracket 43 can be a cylindrical structure, and its interior can have a first receiving cavity 431 that provides travel space for the deformation of the sensor 42. Furthermore, the first opening 432 of the first receiving cavity 431 can face the telescopic assembly 2 and match the radial dimension (the dimension parallel to the radial Y of the housing 1) of the telescopic assembly 2, so that the first receiving cavity 431 can cooperate with the telescopic assembly 2 to achieve the connection between the telescopic assembly 2 and the first bracket 43. The end of the first bracket 43 facing away from the sensor 42 can be used to accommodate the battery 6 of the electronic pen.

[0035] The sensing element 42 may include a strain gauge 421 and an assembly 422. The strain gauge 421 may be a circular plate structure, a rectangular plate structure, or other plate structures with contact surfaces; this embodiment of the present invention does not limit this. The surface of the strain gauge 421 can provide sufficient area for attaching the sensing element 41. A protrusion 4211 is provided at the center of the strain gauge 421 to abut against the end of the telescopic assembly 2. The protrusion 4211 may be hemispherical or spherical. Depending on the pressure applied to the sensing element 42 by the telescopic assembly 2, the degree of compression between the protrusion 4211 and the telescopic assembly 2 varies, causing the strain gauge 421 to deform to different degrees from the protrusion 4211 to the surrounding area. The sensing element 41 may be configured as a resistive strain gauge, attached to the strain gauge 421 around the protrusion 4211. Different resistance values ​​are generated according to the different degrees of deformation of the strain gauge 421, thereby obtaining different pressure values. The end of the protrusion 4211 pointing towards the telescopic assembly 2 along the axial direction X of the housing is recessed towards the body of the strain plate 421 to increase the contact area between the top of the protrusion 4211 and the end of the telescopic assembly 2, disperse the pressure applied by the telescopic assembly 2, and thereby improve the deformation uniformity of the strain plate 421.

[0036] The number of fittings 422 can be two, symmetrically arranged on opposite sides of the strain plate 421. The inner wall of the first bracket 43 is provided with a mounting groove 433. The mounting groove 433 can form a ring along the inner wall of the first bracket 43, or it can be two opposite arc segments on the inner diameter of the first bracket 43. The fittings 422 can be embedded in the mounting groove 433 to achieve the snap-fit ​​fixation of the sensing element 42. In addition, the two ends of the fittings 422 along the radial Y of the housing 1 abut against the bottom of the mounting groove 433 (i.e., the inner wall of the first bracket 43), which can limit the deformation of the strain plate 421, thereby ensuring that the deformation of the strain plate 421 remains uniform, avoiding uneven deformation of the strain plate 421 and the generation of local stress, thereby improving the service life of the strain plate 421 and the entire sensing element 42.

[0037] The electronic pen contains a main circuit board 5 to process the pressure signal received by the sensing element 42 from the sensing element 41. The main circuit board 5 can be a flexible circuit board to be attached to the inner or outer wall of the first support 43. Part of the main circuit board 5 is attached to the inner wall of the first support 43. This part of the main circuit board 5 can contact the strain plate 421 of the sensing element 42. The strain plate 421 can be attached to the main circuit board 5 with structural adhesive. The sensing element 41 is electrically connected to the main circuit board 5. The sensing element 41 can be attached to the side of the strain plate 421 away from the main circuit board 5, or it can be located between the strain plate 421 and the main circuit board 5.

[0038] Optional, in conjunction with reference Figure 5d , Figure 6 , Figure 9 and Figure 10 ,in Figure 9 This is a schematic diagram of the assembly structure of the pen cap assembly 3 included in an electronic pen according to an embodiment of the present invention. Figure 10 Then it is Figure 9 The exploded structure diagram of the pen cap assembly 3 is shown below. The pen cap assembly 3 includes a first electrode 31, an electrode support 32, a second electrode 33, a pen cap shell 34, and a first elastic element 35. The first electrode 31 passes through the electrode support 32 and is connected to the telescopic assembly 2. The pen cap shell 34 is sleeved on the outer wall of the electrode support 32. The second electrode 33 is attached to the inner wall of the electrode support 32. The first elastic element 35 is provided between the second electrode 33 and the telescopic assembly 2. One end of the first elastic element 35 abuts against the second electrode 33, and part of the first elastic element 35 is sleeved on the telescopic assembly 2.

[0039] The pen cap assembly 3 may include two electrodes, namely a first electrode 31 and a second electrode 33, to achieve the target function of the pen cap assembly 3. In this embodiment of the present invention, the first electrode 31 may also be used to connect the pen cap assembly 3 and the telescopic assembly 2. The first electrode 31 passes through the electrode support 32 and is connected to the telescopic assembly 2, so that the electrode support 32 is connected to the telescopic assembly 2. The electrode support 32 has a second receiving cavity 321 and its second opening 322 faces the telescopic assembly 2 so as to receive the telescopic assembly 2 when the pen cap assembly 3 is in the first state. The second electrode 33 is attached to the inner wall of the electrode support 32, that is, the surface of the second receiving cavity 321. Through the first electrode 31 and the second electrode 33, different electrical signals can be generated or received to expand the function of the pen cap assembly 3.

[0040] A first elastic element 35 is sleeved between the second electrode 33 and the telescopic assembly 2. One end of the first elastic element 35 is sleeved on the telescopic assembly 2, and the other end of the first elastic element 35 extends into the second receiving cavity 321 and abuts against the second electrode 33. Through the first elastic element 35, the pen cap assembly 3 can be changed to the second state or maintained in the second state. When the pen cap assembly 3 is pressed, the first elastic element 35 can also be used as a pressure transmission component to transmit pressure to the telescopic assembly 2.

[0041] Optional, refer to Figure 10 The first electrode 31 includes an electrode body 311 and a fixing plate 312; the electrode body 311 is used to connect with the telescopic assembly 2.

[0042] The first electrode 31 may include an electrode body 311 and a fixing plate 312. The electrode body 311 may be threaded and connected to the telescopic component 2, or the electrode body 311 may be connected to a corresponding hole in the telescopic component 2. The fixing plate 312 may be a circular or rectangular plate or other structure with a contact surface. The end of the electrode support 32 away from the telescopic component 2 is provided with a fourth through hole 323. The electrode body 311 of the first electrode 31 passes through the fourth through hole 323, so that the contact surface of the fixing plate 312 is attached to the end of the electrode support 32 away from the telescopic component 2, thereby pressing the end of the electrode support 32 away from the telescopic component 2 against the end of the telescopic component 2. When the electrode body 311 extends into the telescopic component 2, the contact surface of the fixing plate 312 can press the electrode support 32 tightly, thereby achieving a stable connection between the pen cap assembly 3 and the telescopic component 2.

The diameter of the locking part 2412 is larger than the diameter of the connecting part 2411, so that the locking part 2412 and the second sub-chamber 2212 cooperate to limit the movement direction of the push rod 241. The limiting part 2413 passes through the third through hole 2414 in the center of the locking member 242 to limit the movement direction of the locking member 242. One end of the third elastic member 243 abuts against the locking part 2412, and the other end abuts against the periphery of the first through hole 213 of the first bracket 43, so as to cooperate with the push rod 241 and the locking member 242 to realize the locking or unlocking of the self-locking assembly 24.

A guide groove 224 is provided on the inner wall of the third bracket 22 along the axial direction X of the housing 1. The width of the guide groove 224 matches the width of the guide rib 2417, and the guide rib 2417 is engaged in the guide groove 224. The second guide tooth 2416 has a helical tooth structure and extends outward from the third through hole 2414 along the axial direction X of the housing 1. Under the pressing action of the second elastic member 233 and the downward pressure of the locking part 2412, the locking member 242 rotates around the limiting part 2413, so that the pen cap assembly 3, which is directly connected to the self-locking assembly 24, switches between the first and second states and locks. It should be noted that the self-locking component 24, also known as the push-push structure, can be unlocked from one state and switched to another simply by applying a downward pressure action to its pressing component (the push rod 241 and its connected pen cap assembly 3).

In the first state or the second state, the first mark and the second mark are exposed outside the housing in different forms, allowing the user to determine the currently implemented function of the pen cap assembly by observing the first mark and / or the second mark, thereby improving the user experience.
