Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more specifically to a writing device and writing components. Background Technology

[0002] Reflective styluses typically include a reflective element that reflects light emitted from the screen back to the screen's receiver. The screen can then calculate the stylus's position based on the reflected light, thus displaying the handwriting on the screen. However, the reflective element is usually located on the outer surface of the stylus's casing, which makes it prone to wear and tear, and over time, it may wrinkle or even fall off. Utility Model Content

[0003] In view of this, this application provides a writing device and writing component to solve the problems in the prior art where the reflective part is easily worn when it is placed on the outer surface of the reflective stylus, and is prone to wrinkling or even falling off after long-term use.

[0004] In a first aspect, embodiments of this application provide a writing device, comprising a body, a reflective portion, and a protective shell. The reflective portion is disposed around the body for reflecting light emitted by an electronic device. The protective shell is connected to the body and covers the reflective portion, and the protective shell is used to transmit light emitted by the electronic device and light reflected by the reflective portion.

[0005] In this embodiment, by cooperating with the body, the reflective part can be covered by the protective shell, which can prevent external dust, sewage and other substances from contaminating the reflective part and prevent the reflective part from being worn. At the same time, the protective shell can limit the reflective part between the protective shell and the body, thereby preventing the reflective part from wrinkling or falling off after long-term use.

[0006] In one possible implementation, the reflective portion surrounds and covers the body, that is, the reflective portion can cover the circumference of the body, so that the body can reflect light from various directions through the reflective portion in its circumference, which helps to improve the flexibility of the writing device when in use.

[0007] In one possible implementation, the protective shell is provided with a first limiting portion. Along the length direction of the main body, the projection of the first limiting portion at least partially overlaps with the projection of the reflective portion, thereby limiting the movement of the reflective portion and / or the protective shell. The first limiting portion may be an integrally formed structure on the protective shell; exemplarily, it may be an inwardly protruding structure on the protective shell. After the protective shell is installed on the main body, the first limiting portion is located at the end of the reflective portion near the pen tip and can block the end of the reflective portion, thus limiting its movement and preventing it from sliding off the main body. In one embodiment, the first limiting portion may protrude a significant length inward from the protective shell, thereby both blocking the reflective portion and abutting against the end of the main body in the length direction, thus limiting the movement of the protective shell and ensuring the stability of the assembly between the protective shell and the main body.

[0008] In one possible implementation, the main body is provided with a second limiting part, which is used to limit the position of the reflective part. This second limiting part can be a protruding structure integrally formed on the main body, and it engages with the end of the reflective part away from the first limiting part to ensure the accuracy of the reflective part's position. When the reflective part is an independently manufactured reflective film, the second limiting part can also ensure the accuracy of the reflective film's installation position, while preventing the reflective film from moving and ensuring its stability.

[0009] In one possible implementation, the body further includes a step, and a first groove is formed between the step and the second limiting portion. At least a portion of the protective shell is positioned opposite the first groove. The protective shell can be glued to the body, and the first groove facilitates the storage of adhesive, preventing the adhesive from flowing to other non-adhesive locations.

[0010] In one possible implementation, the protective shell has a protrusion that engages with the first groove. During assembly of the protective shell and the main body, the protrusion can engage with the first groove, and the second limiting part and the step can be located on opposite sides of the protrusion along the length of the main body, thereby preventing the protective shell from shifting along the length of the main body after assembly and ensuring the stability of the protective shell during installation.

[0011] In one possible implementation, a second groove is provided on the body and / or the protective shell, and the reflective part is disposed in the second groove. The second groove can provide space for the installation of the reflective part, avoiding the reflective part occupying space other than the body or the protective shell, which helps to save space and achieve the arrangement of the reflective part without changing the overall size of the writing device.

[0012] In one possible implementation, the body includes a mounting portion and a grip portion. The diameter of the mounting portion gradually decreases from the end closest to the grip portion to the end furthest from the grip portion. The reflective portion covers the mounting portion, and the protective shell is fitted onto the mounting portion. The side surface of the mounting portion is inclined at a certain angle relative to the length direction of the body. Since the writing device is usually tilted during writing, by gradually decreasing the diameter of the mounting portion towards the pen tip, interference between the mounting portion and the screen can be avoided when writing in a tilted posture. Simultaneously, the side of the mounting portion facing away from the screen can be made more upright, thus facilitating scanning by light emitted from electronic devices on the screen side.

[0013] In one possible implementation, the outer surface of the mounting portion used to connect the reflector is a conical surface. It is understood that the generatrix of the conical surface is a straight line, and the conical surface extends straight along the direction of the generatrix at all locations. The reflector can fit snugly against the conical surface and be supported by it. The conical surface ensures uniform support at all locations of the reflector, preventing collapse or wrinkles on the reflector, thus ensuring effective light reflection.

[0014] In one possible implementation, the protective shell has a receiving cavity, and the protective shell is fitted onto the body through the receiving cavity. The protective shell is cylindrical and can be fitted onto at least a portion of the body near the pen tip. The sidewalls of the protective shell can be assembled and connected to the body, and can cover the reflective part between the sidewalls of the protective shell and the body, thereby achieving circumferential protection of the reflective part of the writing device.

[0015] In one possible implementation, the protective shell is adhered to or snapped onto the main body. Snapping onto the main body facilitates installation and removal of the protective shell, simplifying operation. Adhesion, on the other hand, ensures a reliable connection between the protective shell and the main body.

[0016] In one possible implementation, the reflective element includes a reflective film or a reflective coating. Both reflective films and reflective coatings can reflect light and can be selectively used according to the actual manufacturing requirements of the writing device.

[0017] In one possible implementation, the reflective part is a reflective coating. The reflective coating can be formed by applying reflective material to the body and / or protective shell through processes such as spraying, so as to form a coating on the body or protective shell. This coating has high processing precision and can reflect light.

[0018] In one possible implementation, the reflective part can be a reflective film, which can be an independently manufactured film material with a certain thickness, and can be connected to the main body and / or protective shell by means of adhesive, thereby facilitating the disassembly and replacement of the reflective film.

[0019] In one possible implementation, the reflective part can be a reflective film, which is clamped between the body and the protective shell. That is, the reflective film can be clamped between the protective shell and the body by the clamping force after the protective shell and the body are assembled, thereby also achieving the fixation of the reflective film. Since no adhesive is needed, it can save costs and also save the space occupied by the adhesive layer.

[0020] In one possible implementation, the protective shell is made of a light-transmitting material. This material allows light of a specified wavelength to pass through; for example, it allows infrared light with wavelengths above 760 nm to pass through, while blocking visible light. In some embodiments, the light-transmitting material can also be transparent. Thus, the protective shell both protects the reflective portion and ensures that the target optical fiber can pass through, thereby ensuring that the writing device can be effectively scanned.

[0021] In one possible implementation, the writing device further includes a writing section connected to the main body, or the writing section is integrally formed with the main body. The writing section is used to cooperate with the reflective section to achieve writing and / or touch control. The writing device can form handwriting on the screen of a display device through the writing section. Exemplarily, the writing section can be manufactured independently and can be connected to the main body using various connection methods. For example, the writing section can be connected to the main body through structural components such as a bracket, or it can be directly connected to the main body through snap-fit, threaded connection, etc., thereby facilitating the disassembly and replacement of the writing section. Exemplarily, to facilitate manufacturing and reduce the number of parts, the writing section can be integrally formed with the main body.

[0022] In one possible implementation, the writing device includes a writing section and a pressure-sensitive component, the writing section being connected to the body via the pressure-sensitive component. At least a portion of the pressure-sensitive component may be connected to the body, and at least another portion may be connected to the writing section. During writing, the writing section is subjected to pressure from the screen of the display device. The pressure-sensitive component can detect this pressure and transmit the pressure signal to a processing device within the writing device or the display device. The processing device can calculate and obtain the position of the writing section to form handwriting on the screen of the display device.

[0023] In one possible implementation, the writing device is a stylus or a finger sleeve. When the writing device is a stylus, the user can write by holding the stylus. When the writing device is a finger sleeve, the finger sleeve can be worn on the user's finger, and handwriting can also be formed by moving the finger on the screen.

[0024] In one possible implementation, when the writing device is a stylus, the writing part of the writing device is a pen tip, which has a pointed tip. The surface of the pointed tip can be spherical, which is conducive to forming finer handwriting and improving the user experience.

[0025] Secondly, embodiments of this application also provide a writing component, which includes a reflective part and a protective shell. The reflective part is used to cover the body of the writing device and also to reflect light emitted by the electronic device. The protective shell is connected to the body and / or the reflective part, and covers the reflective part. The protective shell is used to transmit light emitted by the electronic device and light reflected by the reflective part.

[0026] The writing component provided in this application embodiment covers the reflective part with a protective shell, which can prevent external dust, sewage and other substances from contaminating the reflective part and prevent the reflective part from being worn. At the same time, the protective shell can limit the reflective part between the protective shell and the body, thereby preventing the reflective part from wrinkling or falling off after long-term use.

[0027] In one possible implementation, the protective shell is provided with a first limiting portion. Along the length direction of the main body, the projection of the first limiting portion at least partially overlaps with the projection of the reflective portion, thereby limiting the movement of the reflective portion and / or the protective shell. The first limiting portion may be an integrally formed structure on the protective shell; exemplarily, it may be an inwardly protruding structure on the protective shell. After the protective shell is installed on the main body, the first limiting portion is located at the end of the reflective portion near the pen tip and can block the end of the reflective portion, thus limiting its movement and preventing it from sliding off the main body. In one embodiment, the first limiting portion may protrude a significant length inward from the protective shell, thereby both blocking the reflective portion and abutting against the end of the main body in the length direction, thus limiting the movement of the protective shell and ensuring the stability of the assembly between the protective shell and the main body.

[0028] In one possible implementation, both reflective films and reflective coatings can reflect light, and can be selectively used depending on the actual manufacturing requirements of the writing device.

[0029] In one possible implementation, the reflective part can be a reflective film, which can be an independently manufactured film material with a certain thickness, and can be connected to the main body and / or protective shell by means of adhesive, thereby facilitating the disassembly and replacement of the reflective film.

[0030] In one possible implementation, the reflective part can be a reflective film, which can be clamped between the body and the protective shell. That is, the reflective film can be clamped between the protective shell and the body by the clamping force after the protective shell and the body are assembled, thereby also achieving the fixation of the reflective film. Since no adhesive is needed, it can save costs and also save the space occupied by the adhesive layer.

[0053] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0054] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0055] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0056] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0057] In the description of this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more; the terms "connected," "fixed," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0058] With the development of electronic technology, the types and styles of styluses for writing on electronic screens are becoming increasingly diverse. Examples include capacitive pens, scanning pens with writing functions, and reflective styluses. Reflective styluses typically include a reflective part that reflects light. A radar is usually installed on the screen side. This radar emits light of a set wavelength, such as infrared. The emitted light shines onto the reflective part, which reflects the light back to the radar. The radar receives the reflected light and calculates the position of the reflective stylus based on parameters such as the light's emission angle, reception angle, and transmission time. Furthermore, it can display the written handwriting on the screen using software.

[0059] Figure 1 This is a structural diagram of a reflective stylus in related technologies, such as... Figure 1 As shown, in related technologies, in order to ensure that the reflective part 20 can reflect light emitted from the screen side, the reflective part 20 is usually disposed on the outer surface of the reflective stylus 10. However, this disposal method of the reflective part 20 makes it susceptible to wear and tear, as well as contamination or corrosion from dust, sewage, etc., and the reflective part 20 is prone to wrinkling or even falling off after long-term use. In addition, if the reflective part 20 is wrapped around the circumference of the reflective stylus, there will be a seam at the splicing position of the reflective part 20 itself. When this seam is exposed on the outside of the reflective stylus 10, it will reduce the appearance of the reflective stylus 10.

[0060] This application provides a writing device that enables writing on display devices with display panels, such as computer screens, television screens, and tablet computers. The writing device can be in the form of a stylus, or a regular or irregular shape such as a cylinder, prism, pyramid, or frustum. In some embodiments, the writing device can be used for independent writing; for example, when the writing device is a stylus, the user can write by holding the stylus. Alternatively, the writing device can be a finger sleeve, which can be worn on the user's finger, and handwriting can be formed by moving the finger on the screen. The writing device includes a reflective part for reflecting light emitted from the screen side. In other embodiments, the writing device can be a writing apparatus, meaning it can be attached to other writing products to achieve writing. For example, the writing device is a component of other writing products and can perform some of the functions of the writing products; for instance, the writing device can use the reflective part to perform the positioning function of the writing product, and the writing function can be implemented by other devices within the writing product.

[0061] Figure 2 This is a schematic diagram illustrating the application of the writing device provided in this embodiment, as shown below. Figure 2 As shown, the example of writing on a television screen 30 using the writing device 100 is illustrated. An electronic device for emitting lasers, such as a radar, can be installed on or near the television screen 30. This laser-emitting device can emit light with a set wavelength, such as infrared light. In this embodiment, a lidar 40 is used as an example of a laser-emitting device. The lidar 40 can emit infrared light. The lidar 40 can emit infrared light in its surroundings. When some of the infrared light shines on the reflective part of the writing device 100, the reflective part can reflect this light back to the lidar 40. As explained above, the lidar 40 can calculate the position of the reflective stylus based on parameters such as the laser emission angle, reception angle, and light transmission time, and can further display the written handwriting on the screen 30 through software.

[0062] Figure 3 An exploded view of the writing device provided in the embodiments of this application, such as Figure 3 As shown, in this embodiment, the writing device 100 may include a writing section, a body 1, a reflective section 3, and a protective shell 2. The reflective section 3 may be disposed between the body 1 and the protective shell 2, and the protective shell 2 may cover the reflective section 3, thereby providing protection for the reflective section 3 while allowing light emitted by electronic devices such as lidar to pass through, as well as light reflected by the reflective section 3 to pass through. Specifically, the reflective section 3 may reflect all or nearly all of the light emitted by electronic devices such as lidar. In some embodiments, the reflective section 3 may also reflect a portion of the light emitted by the electronic device; this embodiment does not limit this aspect.

[0063] In one embodiment, the reflective part 3 includes a reflective film or a reflective coating. Both reflective films and reflective coatings can reflect light and can be selectively used according to the actual manufacturing requirements of the writing device. For example, the reflective part 3 is a reflective coating, which can be formed by coating reflective material onto the body 1 and / or the protective shell 2 through processes such as spraying, achieving high processing precision. This coating can reflect light. For example, the reflective part 3 can be a reflective film, which can be an independently manufactured film material with a certain thickness, capable of being connected to the body 1 and / or the protective shell 2 by means of adhesives, thereby facilitating the disassembly and replacement of the reflective film.

[0064] The writing section can be used in conjunction with the reflective section 3 to achieve writing and / or touch control. When the writing device is a stylus, the writing section can be a pen tip 4, which can be partially connected to the body 1. For example, the pen tip 4 can have a pointed tip, the surface of which can be spherical, which is beneficial for forming finer handwriting and improving the user experience. When the writing device is in other forms, the writing section can be in other forms. For ease of explanation, the following description uses a pen tip 4 as an example for the writing section.

[0065] For example, the pen tip 4 can be connected to the body 1 via a pressure-sensitive component (not shown in the figure). At least a portion of the pressure-sensitive component can be connected to the body 1, and at least another portion of the pressure-sensitive component can be connected to the pen tip 4. During the writing process when the pen tip 4 contacts the screen of the display device, the pen tip 4 can be subjected to pressure from the screen. The pressure-sensitive component can detect the pressure on the pen tip 4 and further transmit the pressure signal to the processing device in the writing device or the display device. The processing device can calculate and obtain the position of the pen tip 4, thereby realizing touch control of the writing part to form handwriting on the screen of the display device. For example, the pen tip 4 can also be connected to the body 1 via a structure such as an adapter bracket.

[0066] For example, the pen tip 4 can also be directly connected to the body 1, for example, by means of snap-fit ​​or threaded connection, so that the body 1 and the pen tip 4 can move synchronously to achieve the writing function.

[0067] For example, to facilitate manufacturing and reduce the number of parts, the writing part, such as the pen tip 4, can also be integrally formed with the body 1.

[0068] Among them, such as Figure 3As shown, the main body 1 can be the outer shell of the writing device, which the user can hold to write. The main body 1 can also be used to house and support various devices or structures inside the writing device. For example, the main body 1 can be equipped with circuit boards, pressure-sensitive devices, camera modules, light-emitting components, storage modules, voice modules, etc., thereby enabling the writing device to achieve multiple functions and realize intelligence.

[0069] like Figure 3 As shown, the reflective part 3 can cover the outside of the body 1 and can reflect light emitted by electronic devices such as LiDAR. For example, the reflective part 3 can reflect infrared light or other light with a wavelength of 760nm or higher. Exemplarily, the reflective part 3 can surround the circumference of the body 1, so that the writing device can be recognized by electronic devices such as LiDAR on the screen side under different positions and different usage angles. Of course, in some other embodiments, multiple reflective parts 3 can also be provided, and the multiple reflective parts 3 are distributed at intervals in the circumference of the body 1. This embodiment does not limit this.

[0070] The protective shell 2 can be a separately manufactured structure that can be assembled onto the body 1, for example, by adhesive bonding, thereby ensuring the reliability of the connection between the protective shell 2 and the body 1. In some embodiments, the protective shell 2 and the body 1 can also be connected and fixed by snap-fit, facilitating installation or disassembly and operation. The protective shell 2 can be made of a light-transmitting material that allows light of a specific wavelength to pass through; for example, the light-transmitting material can allow infrared light with wavelengths above 760nm to pass through, while blocking visible light. In some embodiments, the light-transmitting material can also be a transparent material, such as transparent resin, etc., and this embodiment does not impose any limitations on this.

[0071] In one embodiment, the protective shell 2 may not have a perforated structure such as through hole 25, thereby providing comprehensive protection for the reflective part 3, preventing external dust and sewage from contaminating the reflective part 3, and preventing the reflective part 3 from being worn. At the same time, the protective shell 2 can limit the reflective part 3 between the protective shell 2 and the body 1, thereby preventing the reflective part 3 from wrinkling or falling off after long-term use.

[0072] Figure 4 This is a schematic diagram of the structure of the protective shell 2 provided in one embodiment of this application, as shown below. Figure 4As shown, the protective shell 2 can be provided with through holes 25. To improve the appearance, the through holes 25 can be designed with a set pattern to enhance the light reflection effect of the reflective part 3 and ensure that the writing device can be effectively recognized. Since the protective shell 2 has a certain wall thickness, after opening the through holes 25 in a local position on the protective shell 2, the thickness of the protective shell 2 can also prevent external objects from abrading the reflective part 3, and at the same time, it can also prevent the reflective part 3 from being contaminated by a large area of ​​external environment. Moreover, the reflective part 3 can be limited between the protective shell 2 and the main body 1, which can prevent wrinkles or falling off.

[0073] Taking the reflective part 3 as an example of an independently manufactured reflective film, in one assembly method, the reflective film can be first wrapped around the body 1 at a predetermined position and fixed by adhesive. Then, the protective shell 2 can be assembled onto the body 1 so that the protective shell 2 covers the reflective film, thereby protecting the reflective film.

[0074] In another assembly method, taking the reflective part 3 as an independently manufactured reflective film as an example, the reflective film can be first glued to a set position on the protective shell 2, and then the protective shell 2 with the reflective film glued on can be assembled onto the main body 1, so that the reflective film can be placed between the protective shell 2 and the main body 1 to achieve protection of the reflective film.

[0075] When the reflective part 3 is a reflective film or reflective coating, it can be combined with the protective shell 2 to form a component, namely a writing component. The writing component can be assembled as a whole into the body 1, or the writing component can be independently processed, assembled, packaged and transported. This allows the writing component to be flexibly adapted to different bodies 1, thereby expanding the application range of the writing component.

[0076] In one embodiment, the reflective film may be provided with an adhesive backing, which allows it to be bonded to the body 1 and / or the protective shell 2, thereby facilitating the fixation of the reflective film. In another embodiment, the reflective film has adhesive backing on both sides in the thickness direction, allowing it to be bonded to the protective shell 2 and the body 1 respectively via the adhesive backing on both sides. There may be no connection between the protective shell 2 and the body 1, thus achieving relative fixation of the protective shell 2, the reflective film, and the body 1.

[0077] In one embodiment, the reflective film may not have an adhesive backing. The reflective film can be clamped between the protective shell 2 and the body 1 by the clamping force after the protective shell 2 and the body 1 are assembled, thereby achieving the fixation of the reflective film. Since no adhesive is needed, it can save costs and also save the space occupied by the adhesive layer.

[0078] In one embodiment, such as Figure 4As shown, a receiving cavity 24 is provided inside the protective shell 2, and the protective shell 2 is connected to the body 1 through the receiving cavity 24. Exemplarily, the protective shell 2 is cylindrical. During assembly, the protective shell 2 can be fitted onto at least the portion of the body 1 near the pen tip 4. The sidewall of the protective shell 2 can be assembled and connected to the body 1, and the reflective part 3 can be covered between the sidewall of the protective shell 2 and the body 1, thereby achieving circumferential protection of the reflective part 3 of the writing device. In other embodiments, the shape of the protective shell 2 can also be other shapes. For example, the shape of the protective shell 2 can be adapted to the surface shape of the body 1, so that the protective shell 2 can be installed on the body 1 and can cover the reflective part 3. This embodiment does not limit this.

[0079] Figure 5 This is a partial schematic diagram of the body 1 in a writing device provided in one embodiment of this application, as shown below. Figure 5 As shown, a second groove 11 can be provided on the main body 1, and the reflective part 3 can be disposed in the second groove 11. The second groove 11 provides space for the reflective part 3 to be installed on the main body 1, avoiding the reflective part 3 occupying space other than the main body 1, which helps to save space and achieve the arrangement of the reflective part 3 without changing the overall size of the writing device. At the same time, since the reflective part 3 is an independently manufactured reflective film, the second groove 11 can limit the installation of the reflective film, ensuring the positional accuracy of the reflective film, and ensuring the stability of the reflective film after installation.

[0080] The thickness of the reflective part 3 can be less than or equal to the depth of the second groove 11, that is, the reflective part 3 can be entirely disposed in the second groove 11 and will not protrude from the second groove 11. This is beneficial to seal the reflective part 3 in the second groove 11 after the protective shell 2 and the main body 1 are fitted together, thereby improving the protection effect of the reflective part 3.

[0081] Figure 6 This is a cross-sectional view of the protective shell 2 in a writing device provided in one embodiment of this application, as shown below. Figure 6 As shown, a second groove 21 can be provided on the protective shell 2, and the reflective part 3 can be provided in the second groove 21 on the protective shell 2. After the protective shell 2 and the main body 1 are engaged, the reflective part 3 can also be sealed in the second groove.

[0082] In one embodiment, both the protective shell 2 and the body 1 may be provided with a second groove. The second groove on the protective shell 2 and the second groove on the body 1 are positioned opposite each other. A part of the reflective part 3 may be located in the second groove of the body 1, and another part of the reflective part 3 may extend out from the second groove on the body 1 and be disposed in the second groove on the protective shell 2. After the protective shell 2 and the body 1 are assembled, the second groove on the protective shell 2 and the second groove on the body 1 can completely cover the reflective part 3, thereby achieving full protection for the reflective part 3 and avoiding the reflective part 3 occupying additional space.

[0083] Figure 7 This is a schematic diagram of the structure of the body 1 in a writing device provided in one embodiment of this application, as shown below. Figure 7 As shown, the main body 1 may include a mounting portion 12 and a grip portion 13, which are distributed along the longitudinal direction X of the writing device. The pen tip 4 is located on the side of the mounting portion 12 away from the grip portion 13. The mounting portion 12 may be used to house the reflective portion 3 and the protective shell 2. In one embodiment, the main body 1 may be a one-piece molded structure, that is, the mounting portion 12 and the grip portion 13 may be molded simultaneously during the manufacturing process of the main body 1, allowing the user to hold the grip portion 13 to move the writing device for writing.

[0084] During the writing process, the mounting part 12 is closer to the screen surface than the grip part 13. By setting the reflective part 3 on the mounting part 12, the writing position of the writing device can be determined more accurately, which helps to make the writing handwriting appear more ideal.

[0085] Figure 8 A state diagram of the writing device provided in the embodiments of this application during writing, such as... Figure 8 As shown, taking the shape of the mounting part 12 as a rotating body as an example, the diameter of the mounting part 12 gradually decreases from the end closer to the grip part 13 to the end farther away from the grip part 13. That is, the side surface of the mounting part 12 is tilted at a certain angle relative to the length direction X of the body 1. Since the writing device is usually tilted during the writing process, by making the diameter of the mounting part 12 gradually decrease towards the pen tip 4, the interference between the mounting part 12 and the screen can be avoided when the writing device is writing in a tilted posture. At the same time, the side 121 of the mounting part 12 facing away from the screen can also be more upright, so that it is easier to be scanned by electronic devices on the screen side (such as the aforementioned LiDAR 40).

[0086] In some other embodiments, the shape of the mounting part 12 may not be a rotating body. For example, the shape of the mounting part 12 may be prism-shaped. The distance between any two points of the mounting part 12 in the direction perpendicular to the length direction X of the body 1 gradually decreases from the end closer to the gripping part 13 to the end farther away from the gripping part 13. The above effect can also be achieved, which will not be described in detail here.

[0087] Figure 9 This is a partial schematic diagram of the body 1 in a writing device provided in another embodiment of this application, as shown below. Figure 9 As shown, the mounting part 12 can be approximately shaped like a frustum. The outer surface of the mounting part 12 for connecting the reflector 3 is a conical surface 122. It can be understood that the generatrix of the conical surface 122 is a straight line, and each position of the conical surface 122 extends straight along the extension direction of the generatrix. The reflector 3 can fit against the conical surface 122 and be supported by the conical surface 122. The conical surface 122 can ensure that the support effect on each position of the reflector 3 is uniform and consistent, and there will be no problems such as collapse or wrinkles on the reflector 3, thereby ensuring that the reflector 3 effectively reflects light.

[0088] Figure 10 This is a partial schematic diagram of the body 1 in a writing device provided in another embodiment of this application, as shown below. Figure 10 As shown, the reflective part 3 can also be provided on the grip part 13, specifically in a position on the grip part 13 that is difficult for the user's hand to block, thereby also reflecting light during the user's normal writing process. For example, the grip part 13 can be provided with a second groove 11, and the reflective part 3 can be provided in the second groove on the grip part 13. The structure of the protective shell 2 can match the second groove 11 on the grip part 13, so that after the reflective part 3 is provided in the second groove 11 on the grip part 13, the protective shell 2 can close the second groove 11 on the grip part 13, thereby protecting the reflective part 3.

[0089] Figure 11 This is a partial cross-sectional view of a writing device provided in one embodiment of this application, such as... Figure 11 As shown, a first limiting part 22 may be provided on the protective shell 2. Along the length direction X of the body 1, the projection of the first limiting part 22 at least partially overlaps with the projection of the reflective part 3, thereby restricting the movement of the reflective part 3. The first limiting part 22 may be an integrally formed structure on the protective shell 2; for example, the first limiting part 22 may be an inwardly protruding structure on the protective shell 2. After the protective shell 2 is installed on the body 1, the first limiting part 22 is located at the end of the reflective part 3 near the pen tip 4 and can block the end of the reflective part 3 to limit the movement of the reflective part 3 and prevent the reflective part 3 from sliding off the body 1.

[0090] In one embodiment, such as Figure 11 As shown, the first limiting part 22 can protrude a large length into the inner side of the protective shell 2, thereby both blocking the reflective part 3 and abutting against the end of the body 1 in the length direction X, thus ensuring the stability of the assembly of the protective shell 2 and the body 1.

[0091] In one embodiment, such as Figure 10 and Figure 11 As shown, a second limiting part 14 is provided on the main body 1, which is used to limit the position of the reflective part 3. Exemplarily, the second limiting part 14 can be a protruding structure integrally formed on the main body 1, and can continuously surround the circumference of the main body 1. The second limiting part 14 engages with the end of the reflective part 3 away from the first limiting part 22, ensuring the accuracy of the reflective part 3's position. When the reflective part 3 is an independently manufactured reflective film, the second limiting part 14 can also ensure the accuracy of the reflective film's installation position, while preventing the reflective film from moving and ensuring its stability.

[0092] In one embodiment, when the body 1 has the aforementioned second groove for accommodating the reflective part 3, the second limiting part 14 can serve as a sidewall on one side of the second groove. When the first body 1 does not have a groove, multiple second limiting parts 14 can be provided, and these multiple second limiting parts 14 can be spaced apart in the circumferential direction of the body 1, thus also limiting the reflective part 3.

[0093] like Figure 10 and Figure 11 As shown, the main body 1 may also be provided with a step 15, and a first groove 16 is formed between the step 15 and the second limiting part 14. When the protective shell 2 is installed on the main body 1, at least a portion of the protective shell 2 can be positioned opposite the first groove 16. The step 15 is formed at the junction of the mounting part 12 and the grip part 13, and the side of the step 15 facing the pen tip 4 can limit the installation of the protective shell 2. The protective shell 2 can be connected and fixed to the main body 1 by adhesive. The first groove 16 can facilitate the storage of adhesive, preventing the adhesive from flowing to other non-adhesive locations.

[0094] Figure 12 A cross-sectional view of the protective shell 2 in a writing device provided in another embodiment of this application, as shown below. Figure 12 As shown, a protrusion 23 may be provided on the protective shell 2. Combined with... Figure 11 When the protective shell 2 and the main body 1 are assembled, the protrusion 23 on the protective shell 2 can be engaged in the first groove 16 on the main body 1. The second limiting part 14 and the step 15 can be located on both sides of the protrusion 23 in the length direction X of the main body 1, thereby preventing the protective shell 2 from moving in the length direction X of the main body 1 after it is assembled to the main body 1, and ensuring the installation stability of the protective shell 2.

[0095] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
