[0022] This utility model proposes a stylus 100.

[0023] Please see Figures 1 to 6 In one embodiment of this utility model, the stylus 100 includes: a pen holder 1, a circuit assembly 2, and a pen tip assembly 3; the circuit assembly 2 is installed inside the pen holder 1; the pen tip assembly 3 is installed at one end of the pen holder 1, and the pen tip assembly 3 includes a flexible conductive element 31 and a writing element 33. At least a portion of the flexible conductive element 31 is housed inside the pen holder 1, the flexible conductive element 31 elastically abuts against and conducts with the circuit assembly 2, and a portion of the writing element 33 extends outside the pen holder, and the writing element 33 is connected to the flexible conductive element 31.

[0024] In this embodiment, the pen holder 1 is used to house the circuit assembly 2 and the pen tip assembly 3. The pen holder 1 has a mounting hole 11. The circuit assembly 2 is fixedly installed in the inner cavity of the pen holder 1, and the pen tip assembly 3 is installed in the mounting hole 11. The pen tip assembly 3 is connected to the circuit assembly 2 through a flexible conductive element 31. One end of the flexible conductive element 31 is connected to the pen tip assembly 3, and the other end is an elastic contact end. After the pen tip assembly 3 is installed in place, the contact end will abut against the preset metal contact or conductive pad on the circuit assembly 2. The flexible conductive element 31 is elastic. Under the structural constraints of the pen holder 1, the flexible conductive element 31 always maintains an elastic abutment state with the circuit assembly 2 with a certain pre-pressure through its own elastic potential energy, so as to effectively compensate for manufacturing and assembly tolerances, ensure the stability of signal transmission, and buffer the axial impact brought by writing, protect the circuit assembly 2 from mechanical damage, thereby improving the overall durability of the stylus 100. Meanwhile, the use of flexible conductive component 31 can simplify the structure of pen tip assembly 3, thereby reducing the production process of pen tip assembly 3, improving the production efficiency of pen tip assembly 3, and thus improving the production efficiency of stylus 100.

[0025] In this embodiment, the pen tip assembly 3 further includes a writing element 33, which at least partially extends out of the pen holder 1. The writing element 33 can be directly or indirectly connected to the flexible conductive element 31. When the stylus 100 is a passive capacitive pen, the writing element 33 is made of a conductive material, and the electrical connector 32 enables the writing element 33 to remain conductive with the flexible conductive element 31, thereby allowing the writing element 33 to be connected to the circuit assembly 2. When the stylus 100 is an active capacitive pen, the writing element 33 can be replaced with a non-conductive material and made of a material capable of generating damping with the electronic screen. It is then mounted to the pen holder 1 via the electrical connector 32, thereby improving the writing feel of the stylus 100 when writing on the electronic screen. Optionally, the writing element 33 is made of a flexible material. The flexible material prevents the pen tip from slipping when writing with the stylus 100 and can absorb impact through its own deformation, thereby effectively reducing noise and vibration.

[0026] The technical solution of this utility model adopts a pen barrel 1, a circuit component 2, and a pen tip component 3 in the stylus 100. The circuit component 2 is installed inside the pen barrel 1, and the pen tip component 3 is installed at one end of the pen barrel 1. The pen tip component 3 has a flexible conductive element 31 that is at least partially housed inside the pen barrel 1. The flexible conductive element 31 elastically abuts against and conducts with the circuit component 2, so that the pen tip component 3 of the stylus 100 can be connected to the circuit component 2 through the flexible conductive element 31. The flexible conductive element 31 is elastic and can maintain a stable connection and signal transmission between the pen tip component 3 and the circuit component 2. At the same time, it simplifies the structure of the pen tip component 3 of the stylus 100, reduces the assembly time and assembly cost of the pen tip component 3, thereby improving the production efficiency of the stylus 100.

[0027] In one embodiment, the pen tip assembly 3 further includes an electrical connector 32 for connecting the writing element 33 and the flexible conductive element 31. The electrical connector 32 has a first connecting cylinder 321 and a second connecting cylinder 322 connected to each other. The second connecting cylinder 322 is disposed near the end of the circuit assembly 2, and the end of the second connecting cylinder 322 away from the first connecting cylinder 321 has an end wall 322a with a through hole (not shown) for the flexible conductive element 31 to pass through. The writing element 33 is mounted on the first connecting cylinder 321, and the electrical connector 32 is mounted on the second connecting cylinder 322 and passes through the through hole. In this embodiment, the first connecting cylinder 321 is used to mount the writing element 33, and the second connecting cylinder 322 is used to mount the flexible conductive element 31. Both the first connecting cylinder 321 and the second connecting cylinder 322 are conductive. When the writing element 33 is a conductive material, the writing element 33 and the flexible conductive element 31 can be connected through the electrical connector 32, thereby making the entire pen tip assembly 3 conductive and electrically connected to the circuit assembly 2.

[0028] In one embodiment, the flexible conductive element 31 has a first conductive portion 311 and a second conductive portion 312. The first conductive portion 311 is housed in the second connecting cylinder 322, and the second conductive portion 312 passes through the through hole. The outer diameter of the first conductive portion 311 is larger than the outer diameter of the second conductive portion 312, so that a first limiting step 313 is formed between the first conductive portion 311 and the second conductive portion 312, and the end wall 322a abuts against the first limiting step 313. The first limiting step 313 is used to restrict the movement of the flexible conductive element 31 along the axial direction of the stylus 100, thereby preventing the flexible conductive element 31 from falling out of the through hole and causing the connection to break. The flexible conductive element 31 can use its own elastic potential energy to make the first conductive portion 311 and the inner wall of the second connecting cylinder 322 interference fit, and make the second conductive portion 312 and the inner wall of the through hole interference fit, further restricting the relative position of the flexible conductive element 31 and the electrical connector 32.

[0029] In one embodiment, the pen holder 1 has a mounting hole 11 extending axially. The writing component 33 includes a mounting portion 331 and a writing portion 332. The mounting portion 331 is mounted in the first connecting cylinder 321, and the writing portion 332 extends at least partially out of the first connecting cylinder 321 and the mounting hole 11. The writing component 33 is connected and fixed to the first connecting cylinder 321 via the mounting portion 331. The mounting portion 331 can be connected and fixed to the electrical connector 32 by means of interference fit or adhesive connection, or by means of mutually cooperating limiting structures limiting the electrical connector 32. The writing portion 332 extends out of the pen holder 1 and is used to contact the electronic screen for writing on the electronic screen.

[0030] In one embodiment, please refer to Figure 3The outer wall of the mounting part 331 has a groove 331a, and the inner wall of the first connecting cylinder 321 is provided with a limiting block 321a corresponding to the position of the groove 331a. The limiting block 321a is accommodated in the groove 331a. The groove 331a and the limiting block 321a cooperate to restrict the relative position of the writing piece 33 and the electrical connector 32. In this embodiment, the limiting block 321a is arranged in a ring on the outer wall of the mounting part 331, and the groove 331a is arranged in a ring on the inner wall of the first connecting cylinder 321. After the writing piece 33 is assembled into place, the limiting block 321a can be accommodated in the groove 331a. The groove wall of the groove 331a can restrict the position of the limiting block 321a along the axial direction of the stylus 100, thereby restricting the position of the writing piece 33 along the axial direction of the stylus 100. In other embodiments, a groove 331a can be provided on the outer wall of the writing piece 33, and a limiting block 321a can be provided on the inner wall of the first connecting cylinder 321. The limiting block 321a and the groove 331a cooperate to limit the writing piece 33 to the first connecting cylinder 321. In this embodiment, the second limiting block 321a is used to limit the axial displacement of the writing piece 33, so as to prevent the writing piece 33 from being retracted into the first pen holder 1 due to force during writing and thus being unable to extend out of the pen holder 1, resulting in the inability to write.

[0031] Furthermore, the outer diameter of the writing part 332 is larger than the outer diameter of the mounting part 331 so that a second limiting step 333 is formed between the writing part 332 and the mounting part 331. The end of the first connecting cylinder 321 near the writing part 332 abuts against the second limiting step 333, together forming an axial limiting structure to limit the axial movement of the writing piece 33.

[0032] In one embodiment, such as Figure 4 As shown, the pen holder 1 has a mounting hole 11 extending axially. The mounting hole 11 has a first hole segment 111 and a second hole segment 112 arranged sequentially and interconnected along the axial direction of the stylus 100. The second hole segment 112 is located at the end of the first hole segment 111 near the circuit assembly 2. The inner diameter of the first hole segment 111 is larger than the inner diameter of the second hole segment 112, so that a third limiting step 113 is formed between the first hole segment 111 and the second hole segment 112. The end of the first connecting cylinder 321 near the second connecting cylinder 322 abuts against the third limiting step 113. The first hole segment 111 is used to accommodate the first connecting cylinder 321 of the electrical connector 32, and the second hole segment 112 is used to accommodate the second connecting cylinder 322 of the electrical connector 32. The third limiting step 113 is used to limit the relative position of the electrical connector 32 along the axial direction of the stylus 100, so as to prevent the electrical connector 32 from being displaced under force during writing, causing the writing element 33 to retract into the pen holder 1 and not be exposed. The electrical connector 32 can be connected and fixed to the inner wall of the mounting hole 11 by means of interference fit or adhesive connection, or by means of mutually cooperating limiting structure to limit the inner wall of the mounting hole 11.

[0033] In one embodiment, please refer to Figure 3 and Figure 4 The outer wall of the first connecting cylinder 321 has a protrusion 321b, which abuts against the inner wall surface of the first hole section 111. In this embodiment, a protrusion 321b is provided on the outer wall surface of the first connecting cylinder 321 of the electrical connector 32. The protrusion 321b is arranged in a ring around the outer wall of the first connecting cylinder 321, so that the outer diameter of the first connecting cylinder 321 at the protrusion 321b is increased. Thus, the electrical connector 32 is connected and fixed to the pen holder 1 by interference fit between the protrusion 321b and the inner wall of the first hole section 111.

[0034] See Figure 5 In one embodiment, the flexible conductive element 31 and the writing element 33 are integrally molded from the same material, with the writing element 33 extending at least partially beyond the pen holder 1. Specifically, both are made of materials with good elasticity and conductivity, such as conductive silicone, conductive rubber, conductive polymer, conductive fiber fabric, conductive foam, or special composite materials. The writing element 33 extends at least partially beyond the pen holder 1, forming the actual writing contact portion of the stylus 100. The pen tip assembly 3 is made entirely of a flexible conductive material, which ensures a good contact area between the pen tip and the writing surface to obtain a better sensing signal, while also absorbing the impact energy during writing through the elastic deformation of the material itself. This effectively reduces vibration and noise caused by impact with the screen, while avoiding scratches on the screen surface, thus significantly improving the writing effect and user experience of the stylus 100. Furthermore, designing the writing element 33 and the flexible conductive element 32 as an integrally molded structure eliminates the need for the electrical connector 32, which helps simplify the processing steps and improve production efficiency.

[0035] See Figure 6 In one embodiment, the writing element 33 is disposed at one end of the pen holder 1 and covers the outer periphery of the flexible conductive element 31 and the electrical connector 32. The writing element 33 and the pen holder 1 are integrally formed using the same material. Specifically, the writing element 33 covers the outer periphery of the flexible conductive element 31 and is integrally formed using the same material as the pen holder 1. The integrated pen holder structure can better protect the internally integrated flexible conductive element 31. While obtaining a better sensing signal, the closed pen holder 1 can prevent external dust or contaminants from entering the pen holder 1 from the pen tip, thus avoiding damage to the internal parts. At the same time, the flexible conductive element 31 is housed in a closed space, allowing it to be in a stable environment and not easily affected by environmental humidity, temperature, etc. This allows the flexible conductive element 31 to maintain relatively stable elasticity and conductivity for a long time, extending its lifespan and thus extending the lifespan of the stylus 100. In addition, designing the writing element 33 and the pen holder 1 as an integral structure, and designing the electrical connector 32 and the flexible conductive element 31 as an integrally formed structure, also helps to simplify the processing steps and improve production efficiency.

[0036] In one embodiment, the flexible conductive element 31 is made of conductive silicone. Conductive silicone has good elasticity and durability, and can withstand the frequent axial impacts and slight lateral forces of the pen tip assembly 3 during writing. It has strong fatigue resistance and a service life far exceeding that of metal spring sheets that may undergo plastic deformation after long-term compression. At the same time, conductive silicone can increase the contact area between the flexible conductive element 31 and the circuit assembly 2, making the contact more stable and less prone to signal fluctuations due to oxidation or fretting wear. It can also effectively absorb vibrations and serve as a sealant to prevent dust and other contaminants from entering the pen holder 1.

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 scope of protection of the present utility model.
