Description

Technical Field

[0001] This invention relates to the field of stylus technology, and in particular to a stylus. Background Technology

[0002] An electronic stylus is a small, pen-shaped tool used to input commands onto touchscreen devices such as computer screens, mobile devices, and drawing tablets. Users can select documents or draw by tapping the touchscreen with the stylus. With technological advancements, styluses on the market now offer various functions beyond writing, such as erasers and smudgers. These functions are typically switched using a level adjustment mechanism on the stylus. Currently, most stylus level switches are button-type, which are prone to problems such as stuck buttons or detachment, resulting in a shorter lifespan for the stylus. Summary of the Invention

[0022] This invention proposes a stylus 100.

[0023] Please see Figures 1 to 13 In one embodiment of the present invention, the stylus 100 includes: a pen barrel 1, a pen cap 2, a damping component 3, a circuit component 4, and a sensing component 5; the pen cap 2 is rotatably disposed at one end of the pen barrel 1; the damping component 3 is disposed between the pen barrel 1 and the pen cap 2, and is used to generate damping feedback when the pen cap 2 rotates relative to the pen barrel 1; the circuit component 4 is installed on the pen barrel 1; the sensing component 5 is electrically connected to the circuit component 4, and the sensing component 5 is used to sense the rotational movement of the pen cap 2 and send a sensing signal to the circuit component 4, and the circuit component 4 is used to control the working state of the stylus 100 according to the sensing signal.

[0024] In this embodiment, the pen holder 1 has an internal space for housing the circuit assembly 4 and other functional modules. The pen cap 2 is rotatably mounted at one end of the pen holder 1, allowing the user to switch functions or adjust parameters by rotating the pen cap 2. The pen holder 1 and pen cap 2 are respectively located at both ends of the damping assembly 3. When the pen cap 2 rotates relative to the pen holder 1, the damping feedback provided by the damping assembly 3 provides the user with a tactile feedback, allowing the user to identify whether the mode has been switched to the correct position based on this feedback, thereby adjusting the stylus 100 to the preset mode. The circuit assembly 4 is fixedly installed inside the pen holder 1 and includes a main control chip, a power management unit, and signal processing circuits, etc., for powering the stylus 100, analyzing signals, and controlling functions. The sensing assembly 5 is connected between the damping assembly 3 and the circuit assembly 4. When the pen cap 2 of the stylus 100 rotates, the sensing assembly 5 can sense the rotational movement of the pen cap 2 through a signal and send the sensed rotational movement signal to the circuit assembly 4. The circuit assembly 4 adjusts the stylus 100 to the corresponding function based on this signal.

[0025] The technical solution of the present invention employs a pen barrel 1, a pen cap 2, a damping component 3, a circuit component 4, and a sensing component 5 in a stylus 100. The pen cap 2 is rotatably disposed at one end of the pen barrel 1. The damping component 3 is disposed between the pen barrel 1 and the pen cap 2, and is used to generate damping feedback when the pen cap 2 rotates relative to the pen barrel 1. The circuit component 4 is installed in the pen barrel 1. The sensing component 5 is electrically connected to the circuit component 4. The sensing component 5 is used to sense the rotational movement of the pen cap 2 and send a sensing signal to the circuit component 4. The circuit component 4 is used to control the working state of the stylus 100 according to the sensing signal. This allows the stylus 100 to adjust its level function by rotating the pen cap 2. When the pen cap 2 rotates, it can obtain the level adjustment tactile feeling through the damping feedback provided by the damping component 3, and can avoid the problem of stuck keys or keys falling off, thereby extending the service life of the multi-functional stylus 100.

[0026] See Figures 2 to 6In one embodiment, the damping component 3 includes a bracket 31 and a first rotating member 32. The bracket 31 is installed at one end of the pen holder 1 near the pen cap 2. The pen cap 2 has a mounting cavity 21 that is open toward the pen holder 1. The end of the bracket 31 away from the pen holder 1 is inserted into the mounting cavity 21. The first rotating member 32 is fixedly installed in the mounting cavity 21 and is offset from the rotation axis of the pen cap 2. The first rotating member 32 abuts against the bracket 31. In this embodiment, the bracket 31 has a first insertion portion 312 and a second insertion portion 313 connected to each other. The first insertion portion 312 is inserted into the pen holder 1 and fixedly connected to the pen holder 1. The pen cap 2 is rotatably fitted around the periphery of the second insertion portion 313. The end of the second insertion portion 313 opposite to the first insertion portion 312 has a first end wall 313a. The first end wall 313a has a through hole 313b for a fastener to pass through. The fastener rotatably passes through the through hole 313b and is fixedly connected to the pen cap 2. The fastener can act as a pivot for the pen cap 2 so that the pen cap 2 is rotatably connected to the bracket 31. A first rotating member 32 is installed in the mounting cavity 21 of the pen cap 2 and is used to generate a damping feel by relative friction with the bracket 31 when the pen cap 2 rotates.

[0027] See Figures 4 to 7In one embodiment, the first rotating member 32 includes a body 321, a ball 322, and an elastic member 323. The body 321 has a ball groove 321a that opens toward the bracket 31. The ball 322 is movably disposed on the side of the ball groove 321a near the opening. The elastic member 323 elastically abuts against the bottom wall of the ball groove 321a and the ball 322. The bracket 31 has a plurality of receiving grooves 311 at one end near the pen cap 2. The plurality of receiving grooves 311 are spaced apart along the circumference of the bracket 31. The receiving grooves 311 are used to receive the ball 322. The ball 322 can abut against the bottom wall of the receiving groove 311. When the pen cap 2 rotates, the ball 322 can roll into the adjacent receiving groove 311 along the rotation direction of the pen cap 2. In this embodiment, the body 321 has a ball groove 321a extending along the axial direction of the stylus 100. The ball groove 321a has an opening facing towards the side near the bracket 31. The ball 322 is movably mounted in the ball groove 321a near the opening. The inner diameter of the ball groove 321a is slightly larger than the diameter of the ball 322, while the inner diameter of the opening is smaller than the diameter of the ball 322. This ensures that the ball 322 will not fall out of the ball groove 321a when it is in the ball groove 321a. At least a portion of the ball 322 can protrude outside the ball groove 321a. The ball 322 can rotate within the ball groove 321a and slide along the axial direction of the stylus 100. The elastic element 323 elastically abuts against the bottom wall of the ball 322 and the ball groove 321a to continuously apply pressure to the ball 322 toward the bracket 31, so that the ball 322 can remain extended out of the ball groove 321a, thereby allowing the ball 322 to continuously abut against the bracket 31. When the pen cap 2 rotates, the ball 322 can roll from the initial receiving groove 311 to the adjacent receiving groove 311. When the ball 322 rolls over the groove wall between two adjacent receiving grooves 311, the ball 322 can resist the elastic force of the elastic element 323 and slide into the ball groove 321a under the action of the groove wall, so that the ball 322 can cross the groove wall between two adjacent receiving grooves 311 and move from one of the current receiving grooves 311 to the other adjacent receiving groove 311. At this time, under the action of the elastic element 323, the user can feel a large damping touch, thereby sensing whether the setting of the stylus 100 is adjusted properly.

[0028] In one embodiment, the mounting cavity 21 is provided with a limiting groove 211 that mates with the outer contour of the body 321, and the first rotating member 32 is installed in the limiting groove 211. The limiting groove 211 is a cylindrical groove with a diameter slightly larger than that of the body 321, and the cylindrical groove extends along the axial direction of the stylus 100. The first rotating member 32 is inserted into the limiting groove 211, and the ball bearing 322 extends out of the limiting groove 211 to abut against the bracket 31. When the pen cap 2 rotates, the groove wall of the limiting groove 211 can drive the first rotating member 32 to rotate with the pen cap 2.

[0029] See Figures 8 to 13 In one embodiment, the damping assembly 3 includes a first ratchet 33, an elastic element 34, and a second ratchet 35. The first ratchet 33 is axially movable and mounted on the pen holder 1. The second ratchet 35 is connected to the pen cap 2 and can rotate with the pen cap 2. The first ratchet 33 has a first abutting surface 331, and the second ratchet 35 has a second abutting surface 351 that abuts against the first abutting surface 331. The elastic element 34 elastically abuts against the side of the first ratchet 33 opposite to the first abutting surface 331. In this embodiment, the first ratchet 33 and the second ratchet 35 abut against each other through the first abutting surface 331 and the second abutting surface 351, so that the first ratchet 33 and the second ratchet 35 can generate relative friction when they rotate relative to each other, thereby providing a damping feel when adjusting the gear. The elastic element 34 is used to continuously apply pressure to the first ratchet 33 toward the second abutting surface 351, so that the first ratchet 33 and the second ratchet 35 remain in abutting against each other, so as to provide a feel when adjusting the gear.

[0030] In this embodiment, the first ratchet 33 has a first through hole 335 along the axial direction of the pen holder 1. The pen holder 1 has a second end wall 11 near the pen cap 2. The second end wall 11 has a second through hole 111 corresponding to the position of the first through hole 335. The second ratchet 35 is rotatably inserted through the first through hole 335 and the second through hole 111. The second ratchet 35 has a slot 355 near the pen cap 2. The inner wall of the pen cap 2 has a locking block that cooperates with the slot 355. The locking block is inserted into the slot 355 so that when the pen cap 2 rotates, the locking block can drive the second ratchet 35 to rotate. The elastic member 34 elastically abuts between the first ratchet 33 and the second end wall 11 to continuously apply a force toward the second abutment surface 351 to the first ratchet 33.

[0031] See Figures 9 to 13 In one embodiment, the first ratchet 33 includes a first abutting portion 332 and a first mounting portion 333 connected to each other. The outer diameter of the first abutting portion 332 is larger than the outer diameter of the first mounting portion 333, so that a first limiting step 334 is formed between the first abutting portion 332 and the first mounting portion 333. An elastic member 34 is disposed around the periphery of the first mounting portion 333 and abuts against the limiting step. In this embodiment, the first mounting portion 333 is located on the side of the first abutting portion 332 near the second end wall 11. The first limiting step 334 is used to limit the relative position of the elastic member 34 and the first ratchet 33 along the axial direction. The elastic member 34 abuts between the first limiting step 334 and the second end wall 11. The first abutting surface 331 is disposed on the side of the first abutting portion 332 away from the first mounting portion 333. The elastic member 34 can apply pressure toward the second abutting surface 351 to the first ratchet 33 through its own elastic potential energy, so that when the first ratchet 33 and the second ratchet 35 rotate relative to each other, it can provide a strong tactile sensation to the user.

[0032] Furthermore, the outer wall of the first ratchet 33 is also provided with a slider 336, and the side wall of the pen holder 1 is also provided with a groove. When the first ratchet 33 is installed, the slider 336 can slide along the groove to facilitate the assembly of the first ratchet 33 and the pen holder 1. At the same time, after the first ratchet 33 is assembled, the slider 336 is housed in the groove, and the groove wall can restrict the position of the slider 336 along the circumference of the stylus 100, thereby restricting the relative rotation of the first ratchet 33 and the pen holder 1. When the second ratchet 35 rotates, the first ratchet 33 is limited by the cooperation of the slider 336 and the groove and will not be driven to rotate, so that the first ratchet 33 and the second ratchet 35 can rotate relative to each other, thereby providing the user with a damped feel.

[0033] In one embodiment, the second ratchet 35 includes a second abutting portion 352 and a second mounting portion 353 connected to each other. The outer diameter of the second abutting portion 352 is larger than the outer diameter of the second mounting portion 353, so that a second limiting step 354 is formed between the second abutting portion 352 and the second mounting portion 353. The end of the first abutting portion 332 away from the first mounting portion 333 abuts against the second limiting step 354. In this embodiment, the second mounting portion 353 is located at the end of the second abutting portion 352 near the pen cap 2. The end of the second mounting portion 353 near the pen cap 2 is provided with a slot 355. The pen cap 2 can drive the second mounting portion 353 to rotate through a locking block that cooperates with the slot 355, thereby causing the second ratchet 35 to rotate relative to the first ratchet 33. The second abutting surface 351 is provided on the side of the second abutting portion 352 near the second mounting portion 353, so that after the second ratchet 35 and the first ratchet 33 are assembled, the second abutting surface 351 can abut against the first abutting surface 331.

[0034] In one embodiment, a first abutting surface 331 is disposed on the side of the first abutting portion 332 near the second abutting portion 352, and a second abutting surface 351 is disposed on the side of the second abutting portion 352 near the first abutting portion 332. Either the first abutting surface 331 or the second abutting surface 351 has a plurality of protrusions 36 spaced apart along the circumference of the stylus 100. The other abutting surface 331 or the second abutting surface 351 has a plurality of grooves 37 for accommodating the protrusions 36. The plurality of grooves 37 are spaced apart along the circumference of the stylus 100, and the protrusions 36 are disposed one-to-one in the grooves 37. In this embodiment, by setting a protrusion 36 and a groove 37 that cooperates with the protrusion 36, when the first abutment surface 331 and the second abutment surface 351 rotate relative to each other, the protrusion 36 can be transferred from the initial groove 37 to the adjacent groove 37. When the protrusion 36 passes over the groove wall between two adjacent grooves 37, the user can feel a large damping sensation, thereby sensing whether the setting of the stylus 100 is adjusted properly.

[0035] In one embodiment, the sensing component 5 includes a rotary encoder 51, which includes an encoder body 511 electrically connected to the circuit component 4 and a rotating shaft rotatable relative to the encoder body 511. The rotary encoder body 51 is fixedly connected to the pen holder 1, and the rotating shaft is connected to the pen cap 2 and can rotate with the pen cap 2. The rotary encoder body 51 is used to detect the rotation angle of the rotating shaft to determine the rotation position of the pen cap 2. In this embodiment, the encoder body 511 can convert the angular displacement of the rotating shaft into a series of electrical signals and transmit these electrical signals to the circuit component 4 connected to it for interpretation, thereby determining the mode function of the stylus 100. The encoder body 511 can be fixedly installed in a preset position inside the pen holder 1, or the encoder body 511 can be fixedly installed on the first ratchet 33 or the bracket 31 and electrically connected to the circuit component 4. The rotating shaft can rotate relative to the pen cap 2, and one end of it is rigidly connected to the pen cap 2 or the second ratchet 35 through a coupling, interference fit, or snap-fit ​​structure, so that it can rotate synchronously with the rotation of the pen cap 2.

[0036] Understandably, when the user rotates the pen cap 2, its torque is transmitted to the rotating shaft through the transmission structure, driving it to undergo angular displacement relative to the fixed encoder body 511. The encoder body 511 internally detects the absolute rotation angle or relative angular displacement of the rotating shaft in real time based on optical, magnetic, or resistive sensing principles, and converts this mechanical motion into an electrical signal. The circuit component 4 analyzes this signal to determine the real-time rotational position and direction of the pen cap 2, and thus determines the current function setting of the stylus 100.

[0037] In one embodiment, the sensing component 5 includes a Hall sensor 52 and a magnetic element 53. The Hall sensor 52 is fixedly connected to the pen holder 1, and the magnetic element 53 is fixedly connected to the pen cap 2. The Hall sensor 52 is electrically connected to the circuit component 4, and the magnetic element 53 is signal-connected to the Hall sensor 52. The magnetic element 53 can be installed in the second ratchet 35 or the pen cap 2 to rotate synchronously with the pen cap 2 during gear adjustment. The Hall sensor 52 can be fixedly installed in the inner cavity of the pen holder 1, the first ratchet 33, or a preset position on the bracket 31, and is electrically connected to the circuit component 4. The magnetic element 53 and the Hall sensor 52 are connected via a spatial magnetic field signal. When the user rotates the pen cap 2, the magnetic element 53 rotates accordingly, causing its spatial position and angle relative to the Hall sensor 52 to change. The change in position of the magnetic component 53 will cause a change in the magnetic induction intensity or magnetic field direction acting on the Hall sensor 52. The Hall sensor 52 senses this change in magnetic field and converts it into an electrical signal, which is then transmitted to the circuit assembly 4. The circuit assembly 4 senses the current setting of the stylus 100 based on the electrical signal, and adjusts the stylus 100 to the function corresponding to that setting.
