Description

Technical Field

[0001] This utility model relates to the field of electronic devices, and in particular to a stylus. Background Technology

[0002] A stylus is an input tool designed specifically for touchscreen devices, enabling precise control and operation by simulating human touch. When using a stylus, the tip needs to be placed against the touchscreen to make contact. However, traditional styluses struggle to simulate the feel of writing on paper, impacting the user experience.

[0003] Therefore, it is necessary to provide a new stylus to solve the above-mentioned technical problems. Utility Model Content

[0004] The main purpose of this invention is to provide a stylus that solves the technical problem that styluses cannot simulate the writing experience of paper.

[0005] To achieve the above objectives, this utility model proposes a stylus, comprising:

[0006] Pen body;

[0007] A pen tip is disposed at one end of the pen body, and at least a portion of the pen tip is provided with a crystalline structure, the crystalline structure comprising a plurality of regularly arranged crystals, each crystal being one or more of spherical, columnar, plate-like, and needle-like components.

[0008] In one embodiment, the pen tip has a crystalline structure.

[0009] In one embodiment, the crystalline structure is provided on a portion of the pen tip along its radial direction.

[0010] In one embodiment, the pen tip has a central portion located at a central axis and an edge portion circumferentially disposed around the central portion, the crystalline structure being disposed on the edge portion.

[0011] In one embodiment, the pen tip is detachably disposed at one end of the pen body.

[0012] In one embodiment, the pen tip is provided with a mounting post, and one end of the pen body is provided with an internal threaded hole, the mounting post being threaded into the internal threaded hole.

[0013] In one embodiment, the pen tip is tapered from one end close to the pen body to the end away from the pen body; and the end of the pen tip away from the pen body is provided with an arc-shaped contact surface.

[0014] In one embodiment, the pen body includes a housing, a battery, and a circuit board. The housing has a receiving cavity, and both the battery and the circuit board are disposed within the receiving cavity. Both the battery and the pen tip are electrically connected to the circuit board.

[0015] In one embodiment, electrode plates are provided on both sides of the pen tip, and each electrode plate is electrically connected to the circuit board.

[0016] In one embodiment, the number of circuit boards is two, defined as: the two circuit boards are a first circuit board and a second circuit board, respectively;

[0017] The first circuit board is electrically connected to the battery and the pen tip, and is used to control various functions of the stylus; the second circuit board is electrically connected to the battery, and is used to control the start and stop of the stylus.

[0018] The technical solution of this utility model improves the contact damping and friction between the pen tip and the touch screen by incorporating a crystalline structure composed of multiple regularly arranged crystals into the pen tip material. This enhances the tactile feedback of the pen tip when used on the touch screen and produces a sound similar to writing on paper, thus improving the user experience. In this embodiment, the pen body is for the user to grip, and the pen tip is used to contact the touch screen. At least a portion of the pen tip has a crystalline structure composed of multiple regularly arranged crystals. When the stylus is in use, the crystals vibrate due to the energy of the contact movement between the pen tip and the touch screen, promoting and accelerating the energy consumption rate, thereby increasing the contact damping between the pen tip and the touch screen. The crystalline structure also helps to release the stress generated during the pen tip's manufacturing process, increasing the friction between the pen tip and the touch screen. When the stylus tip makes contact with the touchscreen, the additional internal force per unit area is borne by the crystalline structure, hindering the transmission of stress within the tip, enhancing its stress-strain, elasticity, and friction, and thus increasing the contact damping between the tip and the touchscreen. Different shaped crystals vibrate at different points and directions with varying amplitudes and frequencies, resulting in different energy consumption rates. This causes subtle variations in the contact damping between the tip and the touchscreen. Different pen stroke directions produce subtle changes in damping, and this variability in damping provides a three-dimensional feel, making precise pen control easier and providing a delicate tactile vibration. Therefore, the stylus produces a subtle tactile vibration and a sound similar to writing on paper when used on the touchscreen, improving the user experience. Simultaneously, the regularly arranged crystals in the tip stabilize the electromagnetic signal between the stylus and the touchscreen, preventing ink spillage on the touchscreen during use. This stylus is used in electronic devices with touch functionality. Attached Figure Description

[0031] A stylus is an input tool designed specifically for touchscreen devices, enabling precise control and operation by simulating human touch. When using a stylus, the tip needs to be placed against the touchscreen to make contact. In actual production and use, researchers have found that traditional stylus tips are mostly injection-molded from rubber. These tips result in less contact damping and friction between the tip and the touchscreen, making it difficult to simulate the feel of writing on paper and negatively impacting the user experience.

[0032] This invention proposes a stylus to solve the technical problem that styluses cannot simulate the writing experience of paper.

[0033] Please see Figures 1 to 4 In one embodiment of this utility model, the stylus includes a pen body 100 and a pen tip 200. The pen tip 200 is disposed at one end of the pen body 100, and at least a portion of the pen tip 200 is provided with a crystalline structure 210. The crystalline structure 210 includes a plurality of regularly arranged crystals 211, each crystal 211 being one or more of spherical, columnar, sheet-like, and needle-like components. In this embodiment, the regular arrangement of the plurality of crystals 211 can be a stepped arrangement or a mutually overlapping stacked arrangement.

[0034] The technical solution of this utility model improves the contact damping and friction coefficient between the pen tip 200 and the touch screen by setting a crystalline structure 210 composed of a plurality of regularly arranged crystals 211 in the pen tip 200. This enhances the tactile feedback of the pen tip 200 when used on the touch screen and produces a sound similar to writing on paper, thus improving the user experience. In this embodiment, the pen body 100 is for the user to grip, and the pen tip 200 is used to contact the touch screen. At least a portion of the pen tip 200 is provided with a crystalline structure 210 composed of a plurality of regularly arranged crystals 211. When the stylus is in use, the crystals 211 vibrate due to the energy of the contact movement between the pen tip 200 and the touch screen, promoting and accelerating the energy consumption rate, thereby increasing the contact damping between the pen tip 200 and the touch screen. The crystalline structure 210 helps the pen tip 200 release the stress generated during the manufacturing process and increases the friction between the pen tip 200 and the touch screen. When the stylus 200 contacts and moves against the touchscreen, the additional internal force per unit area is borne by the crystalline structure 210, which hinders the transmission of stress within the stylus 200, enhances the stress-strain of the stylus 200, increases its elasticity and friction, and thus improves the contact damping between the stylus 200 and the touchscreen. Different shaped crystals 211 vibrate at different points and in different directions with varying amplitudes and frequencies, resulting in different energy consumption rates. This causes subtle variations in the contact damping between the stylus 200 and the touchscreen. Different pen stroke directions produce subtle changes in damping, and this variability in damping during use creates a three-dimensional feel, making precise pen control easier and providing a delicate tactile vibration. Therefore, the stylus produces a subtle tactile vibration and a sound similar to writing on paper when used on the touchscreen, improving the user experience. Meanwhile, multiple regularly arranged crystals 211 on the pen tip 200 stabilize the electromagnetic signal between the stylus and the touchscreen, preventing the stylus from overflowing onto the touchscreen during use. This stylus is used in electronic devices with touch functionality.

[0035] It should be noted that crystal 211 is a solid substance formed by the periodic arrangement of molecules, atoms, or ions within a material in a three-dimensional space according to a certain pattern. The arrangement of multiple regularly arranged crystals 211 in at least a portion of the pen tip 200 is achieved by adding crystallizing chemical reagents or by adding minute crystallized crystalline substances while the substrate is in a molten state, thus giving the substrate the presence of crystals 211. The reason why the arrangement of multiple regularly arranged crystals 211 in at least a portion of the pen tip 200 can stabilize the electromagnetic signal between the stylus and the touchscreen is that the periodic arrangement of molecules, atoms, or ions within the crystal 211 in a three-dimensional space makes the propagation of electromagnetic waves in the material more stable, reducing scattering and attenuation, and achieving higher signal transmission stability. When voltage is applied to the crystal 211 through the electrode plate 240 at the connection between the pen tip 200 and the pen body 100, the crystal 211 will oscillate due to the piezoelectric effect. This oscillation will create an electric field within the crystal 211, generating a reverse charge. These charges, in turn, affect the oscillation of crystal 211, forming a closed oscillating circuit. When the voltage frequency matches the natural frequency of crystal 211, the amplitude reaches its maximum, forming a piezoelectric resonance and outputting a sinusoidal waveform signal with high spectral purity, achieving higher signal transmission stability. Furthermore, the electric field formed between the regularly arranged crystals 211 interacts with the electric field generated by the touch screen, creating an electromagnetic effect. The resulting electromagnetic attraction or repulsion enhances the damping and elasticity sensation between the pen tip 200 and the touch screen.

[0036] Taking fiber pen tip 200 as an example: adopting a faster stretching rate and a larger stretching ratio, as well as higher temperature, longer stretching time and slower cooling rate in the material manufacturing process will promote the fiber material to have crystals 211, or adding crystallizing chemical reagents in the process can also promote the substrate to have a crystal structure 211.

[0037] In this embodiment, the crystal structure 210 can be a regular arrangement of crystals 211 of one shape, or a regular arrangement of crystals 211 of various different shapes. The crystals 211 can be spherical, columnar, plate-like, or needle-like. Specifically, when multiple crystals 211 of different shapes are combined to form the crystal structure 210, the axial direction of the molecular chains of the plate-like crystals 211 is perpendicular to the long axis of the needle-like crystals 211; the needle-like crystals 211 radiate outward from the spherical crystals 211 as the center, and during growth, the needle-like crystals 211 continuously branch to fill the outer space of the ever-expanding spherical crystals 211; the needle-like crystals 211 can be radially twisted to form ring-shaped crystals 211, and the surface of the needle-like crystals 211 can extend outward to grow many folded chain plates to form a chain crystal structure; two spherical crystals 211 are connected and combined through columnar or needle-like crystals 211 to form a structure formed by the combination of isocubic crystals. During manufacturing, due to the influence of various factors (such as cooling rate, impurities, additives, heat treatment processes, etc.) on the crystals 211, it is difficult to form a single shape of crystals 211 in large quantities inside the pen tip 200. Therefore, in actual manufacturing and use, to save production costs, the crystal structure 210 can adopt a regular arrangement of crystals 211 of various shapes; and to increase contact damping and friction coefficient and improve the user's feel, the crystal structure 210 can be a regular arrangement of spherical crystals 211. However, it should be noted that when manufacturing the crystal structure 210 in the pen tip 200, the crystals 211 need to be generated in small batches multiple times to reduce the generation of crystals 211 of other shapes.

[0038] In this embodiment, the pen tip 200 can be entirely composed of regularly arranged crystals 211, or it can be partially composed of regularly arranged crystals 211. Please refer to [link / reference]. Figure 2 In one embodiment of this invention, the pen tip 200 has a crystalline structure 210. In this embodiment, the pen tip 200 is entirely provided with regularly arranged crystals 211, wherein the crystals 211 generate a piezoelectric effect when a voltage is applied, thus ensuring the basic functions of the stylus. Please refer to [link to relevant documentation]. Figure 3In another embodiment of this utility model, a portion of the pen tip 200 along its radial direction is provided with a crystalline structure 210. In this embodiment, a portion of the pen tip 200 along its radial direction is provided with regularly arranged crystals 211, that is, the crystals 211 are concentrated in a certain direction of the pen tip 200. It should be noted that the pen tip 200 may have 1 / 4, 1 / 2, or other proportions of crystalline structure 210, as long as at least a portion of the pen tip 200 is provided with crystalline structure 210. Furthermore, the larger the proportion of crystalline structure 210, the greater the improvement in contact damping and friction coefficient. Therefore, in actual manufacturing, the proportion of crystalline structure 210 can be designed according to actual needs. Please refer to [link to relevant documentation]. Figure 3 In another embodiment of this utility model, the pen tip 200 is a conductive composite material, and the pen tip 200 has a central portion located at the central axis and an edge portion circumferentially arranged around the central portion, with a crystalline structure 210 disposed on the edge portion. In this embodiment, the crystals 211 are segregated towards the edge portion of the pen tip 200. In a specific embodiment, the pen tip 200 may be a fiber pen tip 200 with conductive material added.

[0039] Please see Figure 1 In one embodiment of this utility model, the pen tip 200 is detachably disposed at one end of the pen body 100. In this embodiment, the pen tip 200 and the pen body 100 are detachably connected, which can reduce the difficulty of assembling and disassembling the stylus. In a specific embodiment, the pen tip 200 is provided with a mounting post 220, and one end of the pen body 100 is provided with an internal threaded hole 110, the mounting post 220 being threadedly connected to the internal threaded hole 110.

[0040] Please see Figure 1 In one embodiment of this utility model, the pen tip 200 is tapered from one end near the pen body 100 to the end away from the pen body 100; and the end of the pen tip 200 away from the pen body 100 is provided with an arc-shaped contact surface 230. In this embodiment, tapering the pen tip 200 from one end near the pen body 100 to the end away from the pen body 100 can improve the operability of the stylus; the contact surface 230 is used to abut against the touch screen, and designing the contact surface 230 as arc-shaped can make the contact between the pen tip 200 and the touch screen smoother, reducing the risk of the touch screen being scratched.

[0041] Please see Figure 1In one embodiment of this utility model, the pen body 100 includes a housing 120, a battery 130, and a circuit board. The housing 120 has a receiving cavity 121, and both the battery 130 and the circuit board are disposed within the receiving cavity 121. Both the battery 130 and the pen tip 200 are electrically connected to the circuit board. In this embodiment, the battery 130 supplies power to the pen tip 200 through the circuit board to create a voltage difference on both sides of the pen tip 200. Electrode plates 240 are disposed on both sides of the pen tip 200, and each electrode plate 240 is electrically connected to the circuit board. The electrode plates 240 disposed on both sides of the pen tip 200 are respectively a positive electrode plate and a negative electrode plate, and the positive electrode plate is connected to the positive terminal of the circuit board, while the negative electrode plate is connected to the negative terminal of the circuit board. Specifically, when the circuit board applies voltage to the crystal 211 through the two electrode plates 240, the molecular structure of the crystal 211 deforms due to the piezoelectric effect, the geometric center changes, and an electromotive force is generated at both ends of the crystal 211. When an electromotive force is applied to the crystal 211, the molecular structure of the crystal 211 is stretched and deformed under the action of the electric field, and the crystal 211 oscillates. This oscillation creates an electric field in the crystal 211, generating reverse charges. These charges, in turn, affect the oscillation of the crystal 211, forming a closed oscillating circuit. When the voltage frequency matches the natural frequency of the crystal 211, the amplitude reaches its maximum, forming a piezoelectric resonance and outputting a sinusoidal waveform signal with high spectral purity, achieving higher stability of the stylus signal transmission. At the same time, the electric field generated by the crystal 211 and the electric field generated by the electronic screen will produce an electromagnetic effect. The resulting electromagnetic attraction or repulsion will enhance the contact damping between the pen tip 200 and the electronic screen and the elastic feel during use. By adjusting the voltage, different electromagnetic forces can be obtained, which will enhance the variability of the contact damping between the pen tip 200 and the electronic screen during use, and thus enhance the three-dimensional feel of use.

[0042] Please see Figure 1 In one embodiment of this utility model, there are two circuit boards: a first circuit board 140 and a second circuit board 150. The first circuit board 140 is electrically connected to the battery 130 and the pen tip 200, and is used to control various functions of the stylus. Its main function is to generate and transmit electrical signals that couple with the signals of the touch screen, thereby achieving precise positioning and pressure sensing. The second circuit board 150 is electrically connected to the battery 130 and is used to control the start and stop of the stylus. It should be noted that the circuit board typically includes an RF transmitter, a pressure detection component, a Bluetooth wireless communication circuit, etc. These components work together to ensure that the stylus can accurately simulate the touch effect of a finger, realizing advanced drawing and writing functions.

[0043] In this embodiment, a tail eraser is provided at the end of the pen body 100 away from the pen tip 200. The tail eraser can erase any traces left on the screen by the stylus tip, facilitating the user's drawing, writing, etc. A charging interface 160 is provided in the center of the tail eraser, which can charge the stylus by connecting an external charging cable.

[0044] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
