Description

Technical Field

[0001] This application relates to the field of terminal technology, and in particular to styluses and electronic device components. Background Technology

[0002] With the increasing popularity of smartphones, tablets, and various digital products, more and more applications require higher precision touch, such as drawing software. As a result, styluses are gradually being widely used in daily study and office work.

[0003] A typical stylus consists of a casing and electronic components located inside the casing. The casing is usually made of plastic, while the electronic components are mostly metal.

[0004] However, plastic casings are prone to damage during long-term use, which seriously affects the user experience. Summary of the Invention

[0005] This application provides a stylus and electronic device assembly, applicable to the field of terminal technology. A buffer is provided between the stylus tip and the pen body to prevent the pen body from easily breaking during long-term use, thus improving the user experience.

[0006] In a first aspect, embodiments of this application provide a stylus, which includes a pen barrel, a pen refill, and a buffer. The pen barrel has a receiving cavity, and a first assembly portion is provided within the receiving cavity. The pen refill is located within the receiving cavity and is fixedly connected to the pen barrel. The buffer portion is located between the first assembly portion and the pen refill, and the buffer portion is elastic. The first assembly portion is used to abut against the pen refill when the pen refill is installed in the pen barrel, via the buffer portion.

[0007] The stylus provided in this embodiment of the application has a first mounting part provided in the receiving cavity of the pen barrel. This allows the positional relationship between the first mounting part and the pen barrel to determine whether the pen tip is properly installed in the pen barrel when the pen tip is installed in the pen barrel. This facilitates the installation of the pen tip in the pen barrel and prevents the pen tip from being affected by improper installation in the pen barrel, which could affect the installation of the pen tip or back cover.

[0008] By providing an elastic buffer between the first assembly and the pen refill, and by having the first assembly abut against the pen refill when the pen refill is installed in the pen barrel, the pen refill can abut against the first assembly when the pen refill is assembled with the pen barrel. Since the buffer is elastic, this reduces wear between the pen refill and the pen barrel.

[0009] In addition, due to the different materials of the pen barrel and the pen refill, the shrinkage of the pen refill is often less than that of the pen barrel in different temperature environments, especially in low temperature environments. By setting an elastic buffer between the first assembly part and the pen refill, the deformation of the buffer can offset the difference between the shrinkage of the pen refill and the pen barrel. This can prevent excessive pressure between the pen barrel and the pen refill when the shrinkage of the pen barrel is greater than that of the pen refill, which could lead to damage to the pen barrel or the pen refill, extend the life of the stylus, and improve the user experience.

[0010] In one possible implementation, the buffer is fixedly connected to one of the first assembly and the pen refill along the axial direction of the pen barrel, and the buffer abuts against the other of the first assembly and the pen refill.

[0011] The stylus provided in this embodiment of the application can be fixedly connected to one of the first assembly part and the pen refill, and then the buffer can be abutted against the other of the first assembly part and the pen refill. In this way, the buffer can be fixed to one of the pen barrel or the pen refill first, and then the pen refill and pen barrel can be assembled so that the buffer abuts against the other of the pen refill or the pen barrel. This makes assembly convenient and reduces the assembly difficulty.

[0012] In one possible implementation, the pen refill includes a second assembly. A buffer is fixed to the second assembly. Abutting the first assembly at one end of the pen barrel along its axial direction.

[0013] The stylus provided in this embodiment of the application, by including a second assembly part in the pen tip, facilitates the assembly of the buffer component onto the pen tip, reducing assembly difficulty. By fixing the buffer component to the second assembly part, the pen tip and the buffer component can be assembled into a whole first, and then the pen tip can be inserted into the pen barrel. Compared to the previous method of placing the buffer component in the pen barrel, this method is easier to assemble, thereby reducing assembly difficulty and improving assembly efficiency.

[0014] In one possible implementation, the buffer includes a mating part that mates with the second assembly part.

[0015] The stylus provided in this embodiment of the application has a mating part on the buffer, which makes it easy to assemble the buffer and the pen tip, improves the connection stability between the pen tip and the buffer, and can prevent the buffer from falling off.

[0016] In one possible implementation, the second assembly includes a raised edge structure. A buffer is fitted over the outside of the pen refill, with one end abutting against the raised edge structure and the other end abutting against the first assembly.

[0017] The stylus provided in this embodiment reduces the assembly difficulty of the buffer by including a raised edge structure in the second assembly part, and having one end of the buffer abut against the raised edge structure and the other end abut against the first assembly part. This simplifies the structure of the second assembly part, thereby reducing the processing difficulty and cost.

[0018] In one possible implementation, the second assembly includes a first groove. The first groove is positioned circumferentially along the pen refill. A portion of the buffer structure is located within and engages with the first groove.

[0019] The stylus provided in this embodiment reduces the radial dimension of the pen tip by including a first groove in the second assembly portion and placing a portion of the buffer structure within the first groove. This eliminates the need to increase the radial dimension of the pen body and allows for easy assembly of the pen tip into the pen body, thereby saving materials and reducing costs. Furthermore, the groove structure facilitates processing, reducing manufacturing difficulty and thus lowering the stylus's manufacturing cost.

[0020] In one possible implementation, the second mounting portion includes a protrusion, and the mating portion includes a second groove. The second groove is disposed along the circumference of the pen refill, and at least a portion of the protrusion is located within the second groove and engages with it.

[0021] The stylus provided in this embodiment includes a protrusion in the second assembly part and a second groove in the mating part. During assembly, the second groove and the protrusion can be connected to form a locking structure, which ensures the connection stability between the buffer and the pen tip and prevents the buffer from shifting.

[0022] In one possible implementation, the number of first assemblies is at least one. Each first assembly has a buffer between it and the pen refill. When there are multiple first assemblies, they are spaced apart along the axial direction of the pen barrel.

[0023] The stylus provided in this application embodiment improves the assembly stability of the pen tip and pen barrel by setting the number of first assembly parts to at least one, preventing relative movement of the pen tip and pen barrel during use, which would affect the user experience and extend the service life of the stylus.

[0024] In one possible implementation, there is an assembly gap between the pen barrel and the pen refill in the radial direction of the pen barrel.

[0025] The stylus provided in this embodiment features an assembly gap between the pen barrel and the pen tip in the radial direction of the barrel. This gap facilitates the installation of the pen tip into the barrel, reducing assembly difficulty and improving assembly efficiency. Furthermore, the assembly gap reduces friction between the pen tip and the pen barrel during assembly. During use, this gap prevents the pen barrel from contacting the pen tip when the pen barrel retracts more than the pen tip, thus preventing damage to either the pen barrel or the pen tip and extending the stylus's lifespan, thereby enhancing the user experience.

[0026] In one possible implementation, an adhesive layer is provided between the pen refill and the pen barrel. This adhesive layer serves to securely connect the pen refill and the pen barrel.

[0027] The stylus provided in this embodiment uses an adhesive layer between the pen tip and the pen body to securely connect them. This adhesive layer provides uniform and strong adhesion, ensuring a firm connection between the pen tip and the pen body, thus extending the stylus's lifespan. The adhesive layer also acts as a shock absorber and buffer, protecting sensitive components from mechanical shocks and vibrations. Furthermore, the adhesive layer can be applied using an automated dispensing system, reducing material waste and labor costs, thereby lowering overall production costs. Automated dispensing systems significantly improve production efficiency and reduce manual operation time and errors. In addition, the adhesive layer enhances product reliability and lifespan, reducing the frequency of repairs and replacements, further lowering costs.

[0028] In one possible implementation, the buffer is an elastic structure or a collapsible structure.

[0029] It should be noted that an "elastic structure" refers to a structure that can deform under external force and return to its original shape and size after the force is removed. This deformation is reversible and conforms to the characteristics of elastic deformation. A "collapse structure," on the other hand, refers to a structure or material that undergoes sudden, nonlinear large deformation or instability under external force. Collapse typically occurs under compressive loads; when the structure's load-bearing capacity reaches a certain critical point, the structure suddenly loses stability and undergoes significant deformation or folding.

[0030] The stylus provided in this embodiment, by setting the buffer to an elastic or collapsible structure, can alleviate the pressure between the pen tip and the pen barrel when there is compressive force between them through the deformation of the buffer itself, thus preventing damage to the pen tip or the pen barrel. Furthermore, setting the buffer to an elastic or collapsible structure can also improve the design flexibility of the buffer. That is, the specific type of buffer can be selected according to the application environment of the stylus, thereby reducing costs and improving the user experience.

[0031] In a possible implementation, the elastic structure includes a combination of one or more of a soft rubber part, a spring, and a shrapnel.

[0032] By setting the elastic structure to include a combination of one or more of a soft rubber part, a spring, and a shrapnel, the design flexibility of the elastic structure can be improved, thereby enhancing the applicability of the stylus pen.

[0033] In a possible implementation, the crush structure includes a crush body with a honeycomb structure or a crush body with a "day character" cross-section.

[0034] It should be noted that the "honeycomb structure" is composed of many hexagonal cells and is similar to a honeycomb. The honeycomb structure can absorb a large amount of energy through the deformation of the cells when受到冲击时 (it is impacted), thereby playing a buffering and protective role. Therefore, by setting the crush structure to include a crush body with a honeycomb structure, the buffering and protective effects of the buffer member can be enhanced, preventing the problem that when the stylus pen is used in an environment with seasonal changes, the pen tip and the pen barrel have different shrinkage dimensions in the length direction due to temperature changes, resulting in extrusion force and easy breakage of the pen barrel.

[0035] The "day character" cross-section is similar to the Chinese character "日", that is, a rectangle with a horizontal line in the middle. This structural form can provide a specific deformation mode when受到冲击时 (it is impacted). When the crush body with a "day character" cross-section is impacted, the horizontal line part in the middle will deform first, and then the entire structure will gradually collapse, thereby absorbing energy. This design can provide relatively uniform energy absorption characteristics and is suitable for application scenarios that require precise control of deformation and energy absorption. Therefore, by setting the crush structure to a crush body with a "day character" cross-section, the design flexibility of the buffer member can be improved, and a buffer member with a smaller size can be rotated according to the deformation ability of the crush structure, thereby reducing the impact on the pen tip, pen barrel, and other components of the stylus pen.

[0036] In a possible implementation, the buffer member is a ring structure.

[0037] For the stylus pen provided in the embodiment of the present application, by setting the buffer member to a ring structure, it is convenient for the assembly of the pen tip. In addition, by setting the buffer member to a ring structure, the ring member can be arranged around the pen tip for one week, so that buffer members are provided at the positions where the pen tip is connected to the first assembly part, thereby protecting each position of the first assembly part, and further preventing the problem that when the shrinkage amount of the pen barrel is greater than that of the pen tip during use, the extrusion force between them is too large, resulting in damage to the pen barrel or pen tip, prolonging the service life of the stylus pen, and enhancing the user experience.

[0038] In one possible implementation, a pen tip and a back cover are also included. The pen barrel includes a first end and a second end disposed along the pen barrel axis. The pen tip is disposed at the first end of the pen barrel and is detachably connected to the pen refill. The back cover is disposed at the second end of the pen barrel and abuts against the pen refill.

[0039] The stylus provided in this embodiment offers more precise touch points than a finger by setting a pen tip, making it suitable for applications requiring high-precision input, such as drawing, writing, and design. In drawing and design software, the pen tip helps users perform detailed operations, such as drawing fine lines, precise coloring, and selecting small areas. The detachable connection between the pen tip and the refill facilitates easy assembly and replacement of the pen tip. This allows users to replace the pen tip themselves if it malfunctions, reducing operational difficulty and maintenance costs. The back cover secures the refill within the pen body, increasing the overall structural strength of the stylus and preventing bending or breakage during use and carrying, thus improving durability. It also protects the internal battery, electronic components, and other sensitive parts from physical damage during use and carrying. The back cover prevents dust, moisture, and other impurities from entering the stylus, keeping internal components clean and functioning properly. Furthermore, some styluses may have an eraser function on the back cover, allowing users to use the eraser for modification and deletion by flipping the stylus over, increasing ease of use. The back cover helps balance the weight distribution of the stylus, improving the grip and writing experience, especially reducing hand fatigue during prolonged use.

[0040] In one possible implementation, the pen barrel is made of plastic. The pen refill comprises multiple metal parts.

[0041] The stylus provided in this embodiment reduces its weight by using a plastic barrel, making it easier to use for extended periods without causing fatigue. Plastic materials are generally cheaper than metals and other high-performance materials, thus lowering production costs. Plastic materials are easy to mold and process, allowing for mass production through processes like injection molding, further reducing manufacturing costs. Plastic materials typically offer a better feel and are less uncomfortable in cold or hot environments compared to metals. Furthermore, plastic materials have excellent electrical insulation properties, preventing static electricity and current interference with electronic components and ensuring proper stylus operation. The plastic material effectively protects the internal electronic components of the stylus from short circuits and other electrical malfunctions.

[0042] By incorporating multiple metal components into the pen tip, the excellent conductivity of these metals allows for better circuit connections and signal transmission, improving the stylus's response speed and sensitivity. The metal components also help dissipate static electricity, preventing static buildup from interfering with the stylus and touchscreen, ensuring proper operation. Their high wear resistance and impact resistance extend the stylus's lifespan and reduce replacement frequency. The high rigidity of the metal components provides better support and fixation, ensuring the stability and reliability of the stylus's internal components. Finally, the high fatigue resistance of metal materials allows them to maintain good mechanical properties during prolonged use.

[0043] Secondly, embodiments of this application provide an electronic device component, including an electronic device and a stylus as described in the first aspect.

[0044] The electronic device provided in this application embodiment has a touch screen. Input is provided to the electronic device by operating the touch screen with a stylus. The electronic device performs operations in response to the input from the stylus. The stylus has an elastic buffer between a first mounting portion of the pen barrel and the pen tip. When the pen tip is installed in the pen barrel, the first mounting portion abuts against the pen tip via the buffer. This allows for contact between the pen tip and the first mounting portion when the pen tip and pen barrel are assembled. Because the buffer is elastic, wear between the pen tip and the pen barrel can be reduced.

[0045] In addition, due to the different materials of the pen barrel and the pen refill, the shrinkage of the pen refill is often less than that of the pen barrel in different temperature environments, especially in low temperature environments. By setting an elastic buffer between the first assembly part and the pen refill, the deformation of the buffer can offset the difference between the shrinkage of the pen refill and the pen barrel. This can prevent excessive pressure between the pen barrel and the pen refill when the shrinkage of the pen barrel is greater than that of the pen refill, which could lead to damage to the pen barrel or the pen refill, extend the life of the stylus, and improve the user experience.

[0046] In one possible implementation, the electronic device component also includes a wireless keyboard having a storage section for storing a stylus.

[0047] By incorporating a storage compartment on the wireless keyboard, the stylus can be neatly stored there, allowing users to easily access it whenever needed and avoiding the hassle of searching for it. The stylus has a designated storage location, reducing the risk of loss, especially in mobile work or frequently used scenarios. Storing the stylus on the wireless keyboard keeps the work area tidy and organized, preventing desktop clutter. Users only need to carry one wireless keyboard, thus accessing both keyboard and stylus functionality, reducing the number of items they need to carry. The storage compartment effectively protects the stylus from physical damage such as bending, breakage, or wear when not in use. It also prevents dust, dirt, and other impurities from adhering to the stylus, keeping it clean and ensuring its proper functioning.

[0048] In one possible implementation, the storage section is a cavity with an opening at at least one end.

[0049] By designing the storage compartment as a cavity with at least one open end, users can easily insert or remove the stylus, making operation simple and convenient. Users can quickly locate the stylus, reducing search time and improving work efficiency. The cavity design effectively protects the stylus from physical damage such as bending, breakage, or wear when not in use. Additionally, the cavity prevents dust, dirt, and other impurities from adhering to the stylus, keeping it clean and ensuring normal use. The one-end open cavity design is typically compact, not taking up too much space and maintaining the overall aesthetics and portability of the wireless keyboard. Storing the stylus in the cavity keeps the work area neat and organized, preventing clutter on the desktop. Attached Figure Description

[0072] To facilitate a clear description of the technical solutions in the embodiments of this application, some terms and technologies involved in the embodiments of this application will be briefly introduced below:

[0073] An "elastic structure" refers to a structure that can deform under external force and return to its original shape and size after the force is removed. This deformation is reversible and conforms to the characteristics of elastic deformation.

[0074] A "collapse structure" refers to a sudden, nonlinear large deformation or instability phenomenon in a structure or material under external forces. Collapse typically occurs under compressive loads. When the load-bearing capacity of a structure reaches a certain critical point, the structure suddenly loses stability and undergoes significant deformation or folding.

[0075] In the embodiments of this application, terms such as "first" and "second" are used to distinguish identical or similar items with substantially the same function and purpose. For example, "first chip" and "second chip" are used only to distinguish different chips and do not limit their order of execution. Those skilled in the art will understand that terms such as "first" and "second" do not limit the quantity or execution order, and that "first" and "second" do not necessarily imply that they are different.

[0076] It should be noted that, in the embodiments of this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design scheme described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0077] In this application embodiment, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, a--c, bc, or abc, where a, b, and c can be single or multiple.

[0078] Figure 1 This is a schematic diagram illustrating a usage scenario of an electronic device component provided in an embodiment of this application. For example... Figure 1As shown, the scene includes a stylus 100, an electronic device 200, and a wireless keyboard 300. Figure 1 The following explanation uses a tablet computer as an example of an electronic device 200. A stylus 100 and a wireless keyboard 300 can provide input to the electronic device 200. The electronic device 200 performs operations in response to the input from the stylus 100 or the wireless keyboard 300. A touch area can be provided on the wireless keyboard 300. The stylus 100 can operate on the touch area of ​​the wireless keyboard 300 to provide input, and the wireless keyboard 300 can perform operations in response to the input from the stylus 100.

[0079] In one embodiment, the stylus 100 and the electronic device 200, the stylus 100 and the wireless keyboard 300, and the electronic device 200 and the wireless keyboard 300 can be interconnected via a communication network to enable wireless signal interaction. This communication network can be, but is not limited to, a Wi-Fi hotspot network, a Wi-Fi peer-to-peer (P2P) network, a Bluetooth network, a Zigbee network, or a near-field communication (NFC) network, or other short-range communication networks.

[0080] It should be noted that the stylus can be, but is not limited to, an inductive stylus and a capacitive stylus. When the electronic device 200 has a touchscreen 201 and the stylus 100 is an inductive stylus, an electromagnetic induction board needs to be integrated on the touchscreen 201 of the electronic device 200 that interacts with the stylus 100. Coils are distributed on the electromagnetic induction board, and the inductive stylus also integrates coils. Based on the principle of electromagnetic induction, within the magnetic field range generated by the electromagnetic induction board, the inductive stylus can accumulate electrical energy as it moves. The inductive stylus can transmit the accumulated electrical energy to the electromagnetic induction board through free oscillation and its coils. The electromagnetic induction board can scan the coils on its surface based on the electrical energy from the inductive stylus to calculate the position of the inductive stylus on the touchscreen 201. The touchscreen 201 in the electronic device 200 can also be called a touch screen, and the stylus 100 can be called a stylus.

[0081] The capacitive stylus can include passive capacitive styluses and active capacitive styluses. Passive capacitive styluses can be called passive capacitive styluses, and active capacitive styluses can be called active capacitive styluses. In this application's embodiments, the type of stylus used does not constitute a limitation on the scope of protection of the embodiments of this application.

[0082] In one possible implementation, such as Figure 2As shown, the wireless keyboard 300 may include a keyboard body 310 and a keyboard cover 320. The keyboard cover 320 is used to hold the electronic device 200, and the keyboard body 310 may be provided with buttons, a touchpad, etc., for user operation. When in use, the keyboard body 310 and keyboard cover 320 of the wireless keyboard 300 can be opened. When not in use, the keyboard body 310 and keyboard cover 320 can be closed.

[0083] In some embodiments, the keyboard body 310 and keyboard sleeve 320 of the wireless keyboard 300 can be rotatably connected. For example, the keyboard body 310 and keyboard sleeve 320 can be connected by a pivot or hinge. Alternatively, in some examples, the keyboard body 310 and keyboard sleeve 320 are rotatably connected by a flexible material (such as leather or fabric). Alternatively, in some examples, the keyboard body 310 and keyboard sleeve 320 can be integrally formed, and the connection between the keyboard body 310 and keyboard sleeve 320 is thinned to allow the connection to be bent. The connection method between the keyboard body 310 and keyboard sleeve 320 may include, but is not limited to, the rotatable connection methods described above.

[0084] See also Figure 2 As shown, to facilitate the storage of the stylus 100, the wireless keyboard 300 may be provided with a storage section 330 for storing the stylus 100. For example, the storage section 330 may be a cylindrical cavity, allowing the stylus 100 to be stored along... Figure 2 Insert it into the storage cavity in the direction of the arrow. In this embodiment, a storage part 330 is provided at the connection between the keyboard body 310 and the keyboard cover 320.

[0085] By incorporating a storage unit 330 on the wireless keyboard 300, the stylus 100 can be stored on the keyboard, allowing users to easily access it whenever needed, eliminating the hassle of searching for it. The stylus 100 has a fixed storage location, reducing the risk of loss, especially in mobile work or frequently used scenarios. Storing the stylus 100 on the wireless keyboard 300 keeps the work area tidy and organized, preventing clutter on the desktop. Users only need to carry one wireless keyboard 300 to have both keyboard and stylus 100 functions, reducing the number of items they need to carry. The storage unit 330 effectively protects the stylus 100 from physical damage such as bending, breakage, or wear when not in use. It also prevents dust, dirt, and other impurities from adhering to the stylus 100, keeping it clean and ensuring its proper use.

[0086] For example, such as Figure 2As shown, the storage section 330 can be a cavity with at least one opening 331. By designing the storage section 330 as a cavity with at least one opening 331, users can easily insert or remove the stylus 100, making operation simple and convenient. Users can quickly find the storage location of the stylus 100, reducing search time and improving work efficiency. The cavity design effectively protects the stylus 100 from physical damage such as bending, breakage, or wear when not in use. In addition, the cavity prevents dust, dirt, and other impurities from adhering to the stylus 100, keeping it clean and ensuring its normal use. The cavity design with one opening 331 is generally compact and does not take up too much space, maintaining the overall aesthetics and portability of the wireless keyboard 300. By storing the stylus 100 in the cavity, the work area can be kept neat and orderly, avoiding clutter on the desktop.

[0087] It should be noted that, in order to prevent the stylus 100 from falling out of the storage compartment 330, in some embodiments, a magnetic material may be provided on the inner wall of the storage compartment 330, and a magnetic material may be provided inside the stylus 100. The stylus 100 is attached to the storage compartment 330 by the magnetic attraction between the magnetic materials.

[0088] Of course, in other examples, when the stylus 100 is fixed to the storage part 330, it may be fixed by magnetic adsorption, for example, the stylus 100 and the storage part 330 may also be fixed by snap-fit.

[0089] To facilitate the removal of the stylus 100 from the storage section 330, a pop-out mechanism can be provided inside the storage section 330. For example, pressing one end of the stylus 100 can cause the pop-out mechanism to drive one end of the stylus 100 to pop outward from the storage section 330.

[0090] The specific structure of the stylus 100 is explained below with reference to the accompanying drawings.

[0091] This application provides a stylus 100, such as... Figure 3 As shown, the stylus 100 may include a pen barrel 110, a pen tip 120, and a back cover 130. The pen barrel 110 includes a first end 111 and a second end 112 arranged along the axial direction of the pen barrel 110. The pen tip 120 is disposed at the first end 111 of the pen barrel 110 and is detachably connected to the pen refill 140. The back cover 130 is disposed at the second end 112 of the pen barrel 110 and abuts against the pen refill 140.

[0092] For example, the pen tip 120 and the pen refill 140, as well as the back cover 130 and the pen barrel 110, can be connected by threaded connection, plug-in or snap-fit. In this embodiment, the connection method between the pen tip 120 and the pen refill 140, and the connection method between the back cover 130 and the pen barrel 110 are not further limited.

[0093] The stylus 100 provided in this embodiment can provide more precise touch points than a finger by setting a pen tip 120, making it suitable for applications requiring high-precision input, such as drawing, writing, and design. In drawing and design software, the pen tip 120 can help users perform detailed operations, such as drawing fine lines, fine coloring, and selecting small areas. By detachably connecting the pen tip 120 to the pen refill 140, it is easy to assemble and replace the pen tip 120. This allows users to replace the pen tip 120 themselves when it malfunctions, reducing the difficulty of operation and maintenance costs.

[0094] By providing the back cover 130, the pen tip 140 can be fixed inside the pen barrel 110, increasing the overall structural strength of the stylus 100 and preventing it from bending or breaking during use and carrying, thus improving durability. It also protects the battery, electronic components, and other sensitive parts inside the stylus 100 from physical damage during use and carrying. The back cover 130 prevents dust, moisture, and other impurities from entering the stylus 100, keeping the internal components clean and functioning properly. Additionally, some stylus 100s may have a back cover 130 with an eraser function, allowing users to flip the stylus 100 and use the eraser for corrections and deletions, increasing ease of use. The back cover 130 helps balance the weight distribution of the stylus 100, improving grip and writing experience, especially reducing hand fatigue during prolonged use.

[0095] like Figure 4 As shown, the stylus 100 may further include a pen tip 140 and a buffer 150. The pen barrel 110 has a receiving cavity 113, and the pen tip 140 is located within the receiving cavity 113 and fixedly connected to the pen barrel 110. After the pen tip 140 is assembled into the receiving cavity 113, the pen tip 120 and the back cover 130 can be assembled. The connection relationship between the pen tip 140 and the pen barrel 110 inside the receiving cavity 113 can be seen in [reference needed]. Figure 5 The description in the text.

[0096] In one possible implementation, the buffer 150 can be a ring structure. The buffer 150 is fitted over the outer side of the second assembly portion 141.

[0097] The stylus 100 provided in this embodiment facilitates the assembly of the pen refill 140 by setting the buffer 150 to a ring structure. Furthermore, by setting the buffer 150 to a ring structure, the ring can surround the pen refill 140, ensuring that the connection points between the pen refill 140 and the first assembly part 114 are all equipped with buffers 150. This protects each position of the first assembly part 114, preventing damage to the pen barrel 110 or pen refill 140 due to excessive pressure between them when the retraction amount of the pen barrel 110 exceeds that of the pen refill 140 during use. This extends the lifespan of the stylus 100 and improves the user experience.

[0098] like Figure 7 As shown, a first assembly part 114 is provided inside the receiving cavity 113. The pen refill 140 is located inside the receiving cavity 113, and a buffer 150 is located between the first assembly part 114 and the pen refill 140. The buffer 150 is elastic. The first assembly part 114 is used to abut against the pen refill 140 through the buffer 150 when the pen refill 140 is installed in the pen barrel 110.

[0099] The stylus 100 provided in this embodiment of the application has a first mounting part 114 provided in the receiving cavity 113 of the pen barrel 110. This allows the positional relationship between the first mounting part 114 and the pen tip 140 to determine whether the pen tip 140 is properly installed in the pen barrel 110 when the pen tip 140 is installed in the pen barrel 110. This facilitates the installation of the pen tip 140 in the pen barrel 110 and prevents the pen tip 120 or the back cover 130 from being affected if the pen tip 140 is not properly installed in the pen barrel 110.

[0100] By providing an elastic buffer 150 between the first assembly part 114 and the pen refill 140, and when the pen refill 140 is installed in the pen barrel 110, the first assembly part 114 abuts against the pen refill 140 through the buffer 150. In this way, when the pen refill 140 and the pen barrel 110 are assembled together, the buffer 150 abuts against the first assembly part 114. Since the buffer 150 is elastic, wear between the pen refill 140 and the pen barrel 110 can be reduced.

[0101] In one possible implementation, the pen barrel 110 can be made of plastic. The pen refill 140 may include multiple metal parts.

[0102] The stylus 100 provided in this embodiment reduces its weight by using a plastic pen body 110, making it easier to use for extended periods without causing fatigue. Plastic materials are generally cheaper than metals and other high-performance materials, thus reducing the production cost of the stylus 100. Plastic materials are easy to mold and process, allowing for mass production through processes such as injection molding, further reducing manufacturing costs. Plastic materials typically offer a better feel and are less uncomfortable in cold or hot environments compared to metals. Furthermore, plastic materials have good electrical insulation properties, preventing static electricity and current interference with electronic components and ensuring the normal operation of the stylus 100. The plastic material effectively protects the internal electronic components of the stylus 100, preventing short circuits and other electrical malfunctions.

[0103] By incorporating multiple metal components into the pen core 140, the excellent conductivity of these metal components allows for proper circuit connections and signal transmission in the stylus 100, improving its response speed and sensitivity. The metal components also help dissipate static electricity, preventing static buildup from interfering with the stylus 100 and touchscreen, ensuring its normal operation. Furthermore, the high wear resistance and impact resistance of the metal components extend the lifespan of the stylus 100 and reduce replacement frequency. The high rigidity of the metal components provides better support and fixation, ensuring the stability and reliability of the internal components of the stylus 100. Finally, the high fatigue resistance of metal materials allows them to maintain good mechanical properties during prolonged use.

[0104] Because the pen body 110 and the pen refill 140 are made of different materials, the pen body 110 is usually made of plastic, while the pen refill 140 is mainly composed of electronic components, so it has more metal parts. The two materials have a large difference in the coefficient of thermal expansion. The coefficient of thermal expansion of plastic is greater than that of metal. In the actual user environment, there are temperature changes similar to the changing seasons. Therefore, due to the difference in the coefficient of thermal expansion, there is a difference in the length direction between the pen refill 140 and the pen body 110 of the stylus 100.

[0105] Table 1 is a comparison of the length dimensions of the pen core 140 and the pen barrel 110 after five styluses 100 were frozen at -40°C for 2 hours.

[0106] Table 1

[0107]

[0108] As shown in Table 1, the shrinkage of the pen barrel 110 in the length direction ranges from 0.26 mm to 0.31 mm, while the shrinkage of the pen refill 140 in the length direction ranges from 0.10 mm to 0.14 mm. It can be seen that the shrinkage of the pen barrel 110 in the length direction is greater than that of the pen refill 140. This difference in length will cause compressive stress at the interface between the pen barrel 110 and the pen refill 140. The more fragile pen barrel 110 is more prone to breakage under compressive stress, leading to cracking of the electronic stylus's outer shell.

[0109] Therefore, the stylus 100 provided in this embodiment of the application, by providing an elastic buffer 150 between the first assembly part 114 and the pen core 140, can offset the difference between the shrinkage amount of the pen core 140 and the pen barrel 110 through the deformation of the buffer 150. This can prevent excessive squeezing force between the pen barrel 110 and the pen core 140 when the shrinkage amount is greater than that of the pen core 140, which could lead to damage to the pen barrel 110 or the pen core 140, thus extending the service life of the stylus 100 and improving the user experience.

[0110] It should be noted that the axial direction of the pen barrel 110 is parallel to the length direction of the pen barrel 110, which is represented by the x-direction in the figure.

[0111] In one possible implementation, the buffer 150 is fixedly connected to one of the first assembly 114 and the pen refill 140 along the axial direction of the pen barrel 110, and the buffer 150 abuts against the other of the first assembly 114 and the pen refill 140.

[0112] In some embodiments, the buffer 150 may be fixedly disposed in the first assembly portion 114, and when the pen refill 140 is assembled into the pen barrel 110, the pen refill 140 abuts against the buffer 150 disposed in the first assembly portion 114. For example, the buffer 150 may be disposed around the first assembly portion 114 and fixedly connected to the first assembly portion 114 by means of bonding, snap-fitting, integral molding, etc. In the embodiments of this application, the connection method between the buffer 150 and the first assembly portion 114 is not further limited.

[0113] In some other embodiments, the buffer 150 may also be fixedly disposed on the pen refill 140. When the pen refill 140 with the buffer 150 is assembled into the pen barrel 110, the pen refill 140 abuts against the first assembly part 114 through the buffer 150. For example, the buffer 150 may be sleeved on the outer wall of the pen refill 140, and a fixed connection with the pen refill 140 may be achieved by means of bonding, snap-fitting, injection molding, etc. In the embodiments of this application, the connection method between the buffer 150 and the pen refill 140 is not further limited.

[0114] The stylus 100 provided in this embodiment of the application can be fixedly connected to one of the first assembly part 114 and the pen refill 140, and the buffer 150 can be abutted against the other of the first assembly part 114 and the pen refill 140. In this way, the buffer 150 can be fixed to one of the pen barrel 110 or the pen refill 140 first, and then the pen refill 140 and the pen barrel 110 can be assembled so that the buffer 150 abuts against the other of the pen refill 140 or the pen barrel 110. This makes assembly convenient and reduces assembly difficulty.

[0115] The following description uses the example of the buffer 150 being fixed to the pen refill 140 and the buffer 150 abutting against the first assembly part 114.

[0116] In some embodiments, such as Figure 6 As shown, the pen refill 140 may include a second assembly portion 141. A buffer member 150 is fixed to the second assembly portion 141. In the axial direction of the pen barrel 110, one end of the buffer member 150 facing the first assembly portion 114 abuts against the first assembly portion 114. The buffer member 150 includes a mating portion 151, which is mated and connected to the second assembly portion 141.

[0117] The stylus 100 provided in this embodiment improves the connection stability between the pen tip 140 and the buffer 150 by including a second mounting portion 141 on the pen tip 140 and a mating portion 151 on the buffer member 150, thus preventing the buffer member 150 from falling off. Including the second mounting portion 141 on the pen tip 140 facilitates the assembly of the buffer member 150 onto the pen tip 140, reducing assembly difficulty. By fixing the buffer member 150 to the second mounting portion 141, the pen tip 140 and the buffer member 150 can be assembled into a single unit before the pen tip 140 is inserted into the pen barrel 110. Since the buffer member 150 is initially positioned within the pen barrel 110, assembly is easier, reducing assembly difficulty and improving assembly efficiency.

[0118] In some embodiments, see continue to see Figure 6 As shown, the second assembly portion 141 may include a protruding edge structure. This protruding edge structure may be arranged circumferentially along the pen refill 140. A buffer member 150 is sleeved on the outside of the pen refill 140, with one end of the buffer member 150 abutting against the protruding edge structure and the other end abutting against the first assembly portion 114. The side of the buffer member 150 near the protruding edge structure is configured as a mating portion 151.

[0119] For example, the buffer 150 and the pen refill 140 can be fixedly connected by means of bonding, injection molding, interference fit, etc. In the embodiments of this application, the fixing method of the buffer 150 and the pen refill 140 is not further limited.

[0120] The stylus 100 provided in this embodiment of the application reduces the assembly difficulty of the buffer 150 and simplifies the structure of the second assembly part 141 by setting the second assembly part 141 to include a raised edge structure, and one end of the buffer 150 abuts against the raised edge structure and the other end abuts against the first assembly part 114. This reduces the processing difficulty and reduces the cost.

[0121] like Figure 7 As shown, the second assembly portion 141 may include a first groove. The first groove is arranged along the circumference of the pen refill 140. A portion of the buffer member 150 is located within the first groove and engages with it. The portion of the buffer member 150 located within the first groove is configured as a mating portion 151.

[0122] For example, the first groove can be a groove structure formed on the outside of the pen refill 140 and surrounding the pen refill 140. The buffer member 150 can be an annular structure. During assembly, a portion of the buffer member 150 is located within the first groove, so that the buffer member 150 is fixedly connected to the pen refill 140. Specifically, in the radial direction of the first groove, a portion of the buffer member 150 is located outside the first groove, so that the buffer member 150 can protrude from the outer wall of the pen refill 140, thereby facilitating the abutment of the first assembly part 114.

[0123] Of course, in other embodiments, such as Figure 8 As shown, there can be multiple first grooves, and multiple first grooves are spaced apart along the circumference of the pen refill 140. The buffer 150 can be a ring structure, and a mating part 151 that mates with the first groove is provided on the inner side of the buffer 150.

[0124] It should be noted that in some embodiments, the mating part may not be provided. For example, the smaller protrusion of the first assembly part can be directly fitted onto the first assembly part because the buffer is elastic, so that the buffer can be fixedly connected to the first assembly part.

[0125] like Figure 9 As shown, the mating part 151 can be a protruding structure spaced along the axial direction of the pen refill 140, and the protruding structure corresponds to the first groove. During assembly, at least a portion of the protruding structure of the buffer member 150 can be located within the first groove, so that the buffer member 150 is fixedly connected to the pen refill 140. In the embodiments of this application, the shape and size of the first groove are not further limited.

[0126] The stylus 100 provided in this embodiment of the application reduces the radial dimension of the buffer 150 by including a first groove in the second assembly part 141 and placing a portion of the buffer 150 within the first groove. This eliminates the need to increase the radial dimension of the pen body 110 and allows for easy assembly of the pen body 110, thereby saving materials and reducing costs. Furthermore, the groove structure facilitates processing, reducing manufacturing difficulty and thus lowering the manufacturing cost of the stylus 100.

[0127] In some embodiments, the second assembly portion 141 may further include a protrusion. For example... Figure 10 As shown, the protrusion can be arranged circumferentially along the pen refill 140. Correspondingly, the mating portion 151 of the buffer 150 can be a second groove, which is arranged inside the buffer 150 and is arranged circumferentially along the buffer. During assembly, the protrusion can be located inside the mating portion 151 and engage with the mating portion 151.

[0128] In other embodiments, such as Figure 11 As shown, there can be multiple protrusions, which are spaced apart circumferentially along the pen refill. Correspondingly, as... Figure 12 As shown, there can be multiple second grooves, which are arranged along the circumference of the pen refill 140. During assembly, the protrusion engages with the second groove to fix the buffer 150 to the second mounting part 141.

[0129] It should be noted that the structure of the second groove corresponds to the protrusion of the second assembly part 141. In this embodiment, the structure of the second groove is not further limited.

[0130] The stylus 100 provided in this embodiment includes a protrusion in the second assembly part 141 and a mating part 151 on the buffer 150 that engages with the protrusion. This facilitates the assembly of the buffer 150 and the pen tip 140, and the protrusion provides high assembly stability, preventing the buffer 150 from falling off. Furthermore, the protrusion is easy to process, reducing processing difficulty and thus lowering processing costs.

[0131] The stylus 100 provided in this embodiment includes a second groove in the mating part 151. During assembly, the second groove and the protrusion can be connected to form a snap-fit ​​structure, ensuring the connection stability between the buffer 150 and the pen core 140 and preventing the buffer 150 from shifting.

[0132] In the embodiments of the present application, the specific shapes of the protruding part and the mating part can be set according to actual needs. In the embodiments of the present application, the shapes of the protruding part and the assembling part are not further limited.

[0133] In a possible implementation manner, the buffer member 150 can be an elastic structure or a collapsible structure.

[0134] In the touch pen 100 provided in the embodiments of the present application, by setting the buffer member 150 as an elastic structure or a collapsible structure, when there is an extrusion force between the pen core 140 and the pen barrel 110, through the self-deformation of the buffer member 150, the pressure between the pen core 140 and the pen barrel 110 can be relieved, preventing the pen core 140 or the pen barrel 110 from being damaged. In addition, by setting the buffer member 150 as an elastic structure or a collapsible structure, the design flexibility of the buffer member 150 can also be improved. That is to say, the specific type of the buffer member 150 can be selected according to the application environment of the touch pen 100 to reduce costs and improve the user experience.

[0135] Exemplarily, the elastic structure can include one or a combination of soft rubber parts, springs, and shrapnel.

[0136] By setting the elastic structure to include one or a combination of soft rubber parts, springs, and shrapnel, the design flexibility of the elastic structure can be improved, and thus the applicability of the touch pen 100 can be enhanced. For example, the soft rubber part can be silicone, natural rubber, fluororubber, polyurethane rubber, thermoplastic elastomer, vulcanized rubber, etc. In the embodiments of the present application, the material of the soft rubber part is not further limited. For example, the spring can be a compression spring, a wave spring, a disc spring, a molded spring, etc. In the embodiments of the present application, the type of the spring is not further limited. The shrapnel can be a compression shrapnel, a wave shrapnel, a butterfly shrapnel, etc. In the embodiments of the present application, the type of the shrapnel is not further limited.

[0137] In a possible implementation manner, the collapsible structure can include a collapsible body with a honeycomb structure or a collapsible body with a "day character" cross-section.

[0138] It should be noted that the "honeycomb structure" is composed of many hexagonal cells, similar to a honeycomb. The honeycomb structure can absorb a large amount of energy through the deformation of the cells when being impacted, thus playing a buffering and protecting role. Therefore, by setting the collapsible structure to include a collapsible body with a honeycomb structure, the buffering and protecting effect of the buffer member 150 can be enhanced, preventing the problem that when the touch pen 100 is used in an environment with seasonal changes, the pen core 140 and the pen barrel 110 have different shrinkage dimensions in the length direction due to temperature changes, resulting in an extrusion force and making the pen barrel 110 prone to breakage.

[0139] The "day character" cross-section is similar to the Chinese character "日", that is, a rectangle with a horizontal line in the middle. This structural form can provide a specific deformation mode when subjected to impact. When the collapsible body with the "day character" cross-section is impacted, the horizontal line part in the middle will deform first, and then the entire structure will gradually collapse, thereby absorbing energy. This design can provide relatively uniform energy absorption characteristics and is suitable for application scenarios that require precise control of deformation and energy absorption. Therefore, by setting the collapsible structure as the collapsible body with the "day character" cross-section, the design flexibility of the buffer member 150 can be improved. According to the deformation ability of the collapsible structure, a buffer member 150 with a smaller size can be rotated, thereby reducing the impact of setting the buffer member 150 on the pen core 140, the pen barrel 110, and other components of the stylus 100. The applicability of the buffer member 150 is enhanced.

[0140] In a possible implementation manner, the number of the first assembly portions 114 is at least one. Among them, a buffer member 150 is provided between each first assembly portion 114 and the pen core 140. When the number of the first assembly portions 114 is multiple, the multiple first assembly portions 114 are arranged at intervals along the axial direction of the pen barrel 110.

[0141] In the embodiment of the present application, by setting the number of the first assembly portions 114 to be at least one, the assembly stability of the pen core 140 and the pen barrel 110 can be improved, preventing the relative movement of the pen core 140 and the pen barrel 110 during use and affecting the user experience, and prolonging the service life of the stylus 100.

[0142] In the embodiment of the present application, the number of the first assembly portions 114 and the buffer members 150 is not further limited. Of course, it can be understood that when the number of the first assembly portions 114 is multiple, the shapes of different assembly portions can be the same or different. In the embodiment of the present application, the shape of the first assembly portions 114 is not further limited. Similarly, when the number of the buffer members 150 is multiple, the shapes of different buffer members 150 can be the same or different. In the embodiment of the present application, the shape of the buffer members 150 is not further limited.

[0143] In a possible implementation manner, as Figure 13 shown, in the radial direction of the pen barrel 110, there is an assembly gap 160 between the pen barrel 110 and the pen core 140.

[0144] The stylus 100 provided in this embodiment has an assembly gap 160 between the pen barrel 110 and the pen tip 140 in the radial direction of the pen barrel 110. This allows the pen tip 140 to be installed into the pen barrel 110, reducing assembly difficulty and improving assembly efficiency. Furthermore, the assembly gap 160 reduces friction between the pen tip 140 and the pen barrel 110 during assembly. During use, this gap prevents the pen barrel 110 from contacting the pen tip 140 when the retraction amount is greater than that of the pen tip 140, thus preventing damage to either the pen barrel 110 or the pen tip 140. This extends the lifespan of the stylus 100 and improves the user experience.

[0145] It should be noted that the assembly gap 160 is greater than the difference in the amount of shrinkage of the pen refill 140 and the pen barrel 110 at different temperatures, so as to assemble the pen refill 140 and the pen barrel 110. In this embodiment of the application, the size of the assembly gap 160 is not further limited.

[0146] In one possible implementation, such as Figure 13 As shown, an adhesive layer 170 is provided between the pen refill 140 and the pen barrel 110. The adhesive layer 170 is used to fix the pen refill 140 and the pen barrel 110 together.

[0147] The stylus 100 provided in this embodiment uses an adhesive layer 170 between the pen tip 140 and the pen body 110 to fix the pen tip 140 and the pen body 110 together. The adhesive layer 170 provides uniform and strong adhesion, ensuring a firm connection between the pen tip 140 and the pen body 110, which helps to improve the service life of the stylus 100. The adhesive layer 170 also acts as a shock absorber and buffer, protecting sensitive components from mechanical shock and vibration damage. In addition, the adhesive layer 170 can be set by an automated dispensing system, which can reduce material waste and labor costs, thereby reducing overall production costs. Automated dispensing systems can significantly improve production efficiency and reduce manual operation time and errors. Furthermore, the adhesive layer 170 can improve product reliability and service life, reduce the frequency of maintenance and replacement, and thus reduce costs.

[0148] It should be noted that, in this embodiment of the application, the size of the adhesive layer 170 is not further limited, as long as the adhesive layer 170 is provided.

[0149] It should be noted that during assembly, the pen refill 140 can be assembled first, then glue can be applied to the pen refill 140, then the pen refill 140 can be inserted into the pen barrel 110, and finally the pen tip 120 and the back cover 130 can be assembled. During the assembly process, the assembly pressure between the pen refill 140 and the first assembly part 114 of the pen barrel 110 is less than the collapse threshold of the buffer 150. That is to say, during the assembly process of the pen refill 140 and the pen barrel 110, the buffer 150 itself will not undergo shrinkage strain, or the amount of shrinkage is small, ensuring that the assembly is in place.

[0150] It should be noted that when the pen refill 140 is assembled inside the pen barrel 110, the buffer 150 still has a large shrinkage margin. When there is compressive stress between the pen refill 140 and the pen barrel 110, and the compressive stress is greater than the collapse threshold of the buffer 150 itself, it can shrink to absorb the compressive stress and prevent the pen barrel 110 from cracking.

[0151] Of course, in other embodiments, the stylus 100 can be assembled in other ways. In this embodiment, the assembly method of the stylus 100 is not further limited.

[0152] like Figure 14 As shown in the figure, this application provides an electronic device component, including an electronic device 200 and a stylus 100 of any of the above embodiments.

[0153] The electronic device 200 provided in this application embodiment has a touch screen 201. Input is provided to the electronic device 200 by operating the touch screen using a stylus 100. The electronic device 200 performs operations in response to the input from the stylus 100. The stylus 100 has an elastic buffer 150 between a first mounting portion 114 of the pen barrel 110 and a pen tip 140. When the pen tip 140 is installed in the pen barrel 110, the first mounting portion 114 abuts against the pen tip 140 through the buffer 150. This allows the pen tip 140 to abut against the first mounting portion 114 when assembled with the pen barrel 110. Since the buffer 150 is elastic, wear between the pen tip 140 and the pen barrel 110 can be reduced.

[0154] In addition, since the pen barrel 110 and the pen refill 140 are made of different materials, the shrinkage of the pen refill 140 is often less than that of the pen barrel 110 in different temperature environments, especially in low temperature environments. By setting an elastic buffer 150 between the first assembly part 114 and the pen refill 140, the difference between the shrinkage of the pen refill 140 and the pen barrel 110 can be offset by the deformation of the buffer 150. This can prevent excessive squeezing force between the pen barrel 110 and the pen refill 140 when the shrinkage of the pen barrel 110 is greater than that of the pen refill 140, which could lead to damage to the pen barrel 110 or the pen refill 140, thus extending the service life of the stylus 100 and improving the user experience.

[0155] It should be understood that the electronic devices in the embodiments of this application may be referred to as user equipment (UE), terminals, etc. For example, electronic devices may be portable Android devices (PADs), personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices, in-vehicle devices, or wearable devices; virtual reality (VR) terminal devices; augmented reality (AR) terminal devices; wireless terminals in industrial control; wireless terminals in self-driving; wireless terminals in remote medical care; wireless terminals in smart grids; wireless terminals in transportation safety; wireless terminals in smart cities; wireless terminals in smart homes; and other mobile or fixed terminals with touchscreens. The embodiments of this application do not specifically limit the form of the terminal device.

[0156] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
