Description

Technical Field

[0001] This invention relates to a stylus, and more particularly to a stylus with magnetic induction. Prior Technology

[0002] A stylus is a device that uses a magnetic field to sense handwriting. However, when drawing on a monitor with a stylus, the monitor's magnetic sensor only detects one type of magnetic flux, resulting in a single stroke color after signal conversion. If other stroke colors are desired, the stylus needs to be replaced. Therefore, how to achieve multiple stroke colors with a single stylus has become a problem to be solved. Summary of the Invention

[0003] Therefore, the object of the present invention is to provide a stylus with variable magnetism.

[0004] Therefore, the stylus of the present invention includes a pen arm and a magnetic force generating device.

[0005] The pen barrel has a accommodating space.

[0006] The magnetic force generating device is partially disposed within the accommodating space. The magnetic force generating device is configured to cause the pen barrel to generate at least two different magnetic states.

[0007] In some embodiments, the pen barrel includes a first pen tip and a second pen tip opposite to the first pen tip. The magnetic force generating device includes a first magnet and a second magnet. The first magnet and the second magnet each have a first polarity and a second polarity different from the first polarity. The first polarity of the first magnet is adjacent to the first pen tip so that the first pen tip has the first polarity. The second polarity of the second magnet is adjacent to the second pen tip so that the second pen tip has the second polarity. These magnetic states are respectively a first magnetic state in which the first pen tip has the first polarity and a second magnetic state in which the second pen tip has the second polarity.

[0008] In some embodiments, the pen barrel also includes a first transparent display window adjacent to the first pen tip and a second transparent display window adjacent to the second pen tip. The magnetic force generating device includes a first color ring and a second color ring corresponding to the first and second transparent display windows, respectively. The first and second color rings are different colors and are used to represent the pen marks that the pen barrel can produce in the first magnetic state and the second magnetic state, respectively.

[0009] In some embodiments, the pen barrel further includes a first end sleeve and a second end sleeve. The first end sleeve has a first pen tip receiving groove for receiving the first pen tip, and a first magnet receiving groove opposite to the first pen tip receiving groove for receiving the first magnet. The second end sleeve has a second pen tip receiving groove for receiving the second pen tip, and a second magnet receiving groove opposite to the second pen tip receiving groove for receiving the second magnet.

[0010] In some embodiments, the magnetic force generating device further includes a sliding assembly slidably connected to the pen barrel, a first adsorption magnet disposed on the sliding assembly and located within the accommodating space and facing the first magnet, and a second adsorption magnet disposed on the sliding assembly and located within the accommodating space and facing the second magnet. The sliding assembly can be operated to slide relative to the pen barrel to cause the first adsorption magnet to adsorb onto the first magnet, or to cause the second adsorption magnet to adsorb onto the second magnet. The pen barrel can also generate a third magnetic state and a fourth magnetic state. In the third magnetic state, the first adsorption magnet is adsorbed onto the first magnet. In the fourth magnetic state, the second adsorption magnet is adsorbed onto the second magnet.

[0011] In some embodiments, the sliding component can slide between an initial position and a first position, and between the initial position and a second position. In the initial position, the first magnetic magnet is spaced apart from and does not attract the first magnet, and the second magnetic magnet is spaced apart from and does not attract the second magnet. In the first position, the first magnetic magnet attracts the first magnet. In the second position, the second magnetic magnet attracts the second magnet.

[0012] In some embodiments, the pen barrel also forms a groove communicating with the receiving space. The sliding assembly includes a sliding sleeve slidably received within the receiving space, and a button slidably passing through the groove and connected to the sliding sleeve for pressing. The first and second magnetic magnets are disposed within the sliding sleeve.

[0013] In some embodiments, the pen barrel further includes a first transparent display window adjacent to the first pen tip and a second transparent display window adjacent to the second pen tip. The sliding sleeve includes a first color ring adjacent to the first pen tip, a second color ring adjacent to the second pen tip, a third color ring located on the side of the first color ring opposite to the first pen tip, and a fourth color ring located on the side of the second color ring opposite to the second pen tip. When the sliding component is in its initial position, the first color ring and the second color ring correspond to the first transparent display window and the second transparent display window, respectively. When the sliding component is in its first position, the third color ring and the second color ring correspond to the first transparent display window and the second transparent display window, respectively. When the sliding component is in its second position, the first color ring and the fourth color ring correspond to the first transparent display window and the second transparent display window, respectively. The first, second, third, and fourth color rings are different colors and are used to represent the pen marks that the pen can produce in the first, second, third, and fourth magnetic states, respectively.

[0014] In some embodiments, the sliding sleeve forms a receiving space having a first opening and a second opening opposite to the first opening. A first magnetic magnet is fixed to the receiving space and has a first magnetic surface exposed through the first opening for attracting the first magnet. A second magnetic magnet is fixed to the receiving space and has a second magnetic surface exposed through the second opening for attracting the second magnet.

[0015] In some embodiments, the sliding sleeve forms two slots. The button has a pressing plate for pressing and two hooks disposed opposite to the pressing plate, the hooks passing through the sliding groove and respectively engaging with the slots.

[0016] In some embodiments, the pen barrel includes a pen tip. The magnetic force generating device includes a magnet disposed within the receiving space and adjacent to the pen tip, a sliding assembly slidably connected to the pen barrel, and an adsorption magnet disposed within the receiving space and facing the magnet, located on the sliding assembly. The sliding assembly can be operated to slide relative to the pen barrel to cause the adsorption magnet to adsorb onto or move away from the magnet. One of these magnetic states is that the adsorption magnet is away from the magnet. When the adsorption magnet is away from the magnet, the pen barrel is in one of these magnetic states. When the adsorption magnet adsorbs onto the magnet, the pen barrel is in another of these magnetic states.

[0017] The advantage of this invention is that the stylus, through a magnetic force generating device, enables the pen barrel to generate at least two different magnetic states, and different pen colors can be produced according to different magnetic states during use. Therefore, the same stylus can achieve the effect of having multiple pen colors. Simple Explanation of the Diagram

Implementation

[0019] Before the invention is described in detail, it should be noted that similar elements are represented by the same numbers in the following description.

[0020] Referring to Figures 1 to 4, one embodiment of the stylus 100 of the present invention is shown. The stylus 100 is suitable for touch writing on a panel 9 (see Figure 6). The stylus 100 includes a pen arm 1 and a magnetic force generating device 2.

[0021] The pen barrel 1 includes a barrel 10, a first pen tip 11 located at one end of the barrel 10, a second pen tip 12 located at the other end of the barrel 10 and opposite to the first pen tip 11, a first transparent display window 13 disposed on the barrel 10 and adjacent to the first pen tip 11, a second transparent display window 14 disposed on the barrel 10 and adjacent to the second pen tip 12, a first end sleeve 15 disposed on the barrel 10 and carrying the first pen tip 11, and a second end sleeve 16 disposed on the barrel 10 and carrying the second pen tip 12. The barrel 10, the first end sleeve 15, and the second end sleeve 16 together define a receiving space 101. The barrel 10 forms a groove 17 communicating with the receiving space 101. The first end sleeve 15 has a first pen tip receiving groove 151 for receiving the first pen tip 11, and a first magnet receiving groove 152 opposite to the first pen tip receiving groove 151 for receiving part of the magnetic force generating device 2. The second end sleeve 16 has a second pen tip receiving groove 161 for receiving the second pen tip 12, and a second magnet receiving groove 162 opposite to the second pen tip receiving groove 161 for receiving part of the magnetic force generating device 2.

[0022] The magnetic force generating device 2 is partially disposed within the accommodating space 101. The magnetic force generating device 2 includes a first magnet 21 disposed in the first magnet accommodating groove 152, a second magnet 22 disposed in the second magnet accommodating groove 162, a sliding assembly 23 slidably connected to the pen barrel 1, a first adsorption magnet 24 disposed in the sliding assembly 23 and located within the accommodating space 101 and facing the first magnet 21, and a second adsorption magnet 25 disposed in the sliding assembly 23 and located within the accommodating space 101 and facing the second magnet 22.

[0023] The sliding assembly 23 includes a sliding sleeve 231 slidably housed within the receiving space 10, and a button 232 slidably passing through the slide groove 17 and connected to the sliding sleeve 231 for pressing. The sliding sleeve 231 forms a receiving space 2311. The receiving space 2311 has a first opening 2313 and a second opening 2314 opposite to the first opening 2313. The first magnetic magnet 24 and the second magnetic magnet 25 are disposed within the receiving space 2311 of the sliding sleeve 231. The first magnetic magnet 24 is fixed to the receiving space 2311 and has a first magnetic surface 241 exposed in the first opening 2313 for attracting the first magnet 21. The second magnetic magnet 25 is fixed to the receiving space 2311 and has a second magnetic surface 251 exposed in the second opening 2314 for attracting the second magnet 22. The first adsorption surface 241 can be directly adsorbed onto the first magnet 21 and can enhance the magnetism of the first magnet 21. The second adsorption surface 251 can be directly adsorbed onto the second magnet 22 and can enhance the magnetism of the second magnet 22.

[0024] The sliding sleeve 231 also forms two slots 2312. The button 232 has a pressing plate 2321 for pressing, and two hooks 2322 disposed opposite to the pressing plate 2321. The hooks 2322 pass through the slide groove 17 and are respectively engaged with the slots 2312. The pressing plate 2321 is for the user to press.

[0025] Referring to Figures 5 to 12, the sliding component 23 can slide between an initial position (refer to Figures 5 to 8) and a first position (refer to Figures 9 and 10), and between the initial position and a second position (refer to Figures 11 and 12). In the initial position, the first magnet 24 is spaced apart from the first magnet 21 and does not attract the first magnet 21, and the second magnet 25 is spaced apart from the second magnet 22 and does not attract the second magnet 22. In the first position, the first magnet 24 attracts the first magnet 21. In the second position, the second magnet 25 attracts the second magnet 22.

[0026] The magnetic force generating device 2 is configured to generate four different magnetic states in the pen barrel 1. The first magnet 21 and the second magnet 22 each have a first polarity and a second polarity different from the first polarity. The first polarity and the second polarity are N pole and S pole, respectively. The first polarity of the first magnet 21 is adjacent to the first pen tip 11 so that the first pen tip 11 has the first polarity. The second polarity of the second magnet 22 is adjacent to the second pen tip 12 so that the second pen tip 12 has the second polarity. These magnetic states are a first magnetic state in which the first pen tip 11 has the first polarity, and a second magnetic state in which the second pen tip 12 has the second polarity. The sliding component 23 can be operated to slide relative to the pen barrel 1 to cause the first adsorption magnet 24 to adsorb onto the first magnet 21, or to cause the second adsorption magnet 25 to adsorb onto the second magnet 22. The pen barrel 1 can also generate a third magnetic state and a fourth magnetic state. In the third magnetic state, i.e., when the sliding component 23 is in the first position, the first adsorption magnet 24 is adsorbed onto the first magnet 21. In the fourth magnetic state, i.e., when the sliding component 23 is in the second position, the second adsorption magnet 25 is adsorbed onto the second magnet 22.

[0027] The sliding sleeve 231 includes a first color ring 2315 adjacent to the first pen tip 11, a second color ring 2316 adjacent to the second pen tip 12, a third color ring 2317 located on the side of the first color ring 2315 opposite to the first pen tip 11, and a fourth color ring 2318 located on the side of the second color ring 2316 opposite to the second pen tip 12. When the sliding component 23 is in its initial position, the first color ring 2315 and the second color ring 2316 correspond to the first transparent display window 13 and the second transparent display window 14, respectively. When the sliding component 23 is in its first position, the third color ring 2317 and the second color ring 2316 correspond to the first transparent display window 13 and the second transparent display window 14, respectively. When the sliding component 23 is in its second position, the first color ring 2315 and the fourth color ring 2318 correspond to the first transparent display window 13 and the second transparent display window 14, respectively. The first color ring 2315, the second color ring 2316, the third color ring 2317, and the fourth color ring 2318 are different colors and are used to represent the pen marks that the pen barrel 1 can produce in the first magnetic state, the second magnetic state, the third magnetic state, and the fourth magnetic state, respectively.

[0028] When a user writes on the panel 9 using the stylus 100, at the initial position (see Figures 5 and 6), the first pen tip 11 produces a pen color similar to the first color ring 2315 corresponding to the first transparent display window 13, such as black, but not limited to this. To use a different pen color, also at the initial position (see Figures 7 and 8), without moving the sliding component 23, the stylus 100 is switched to use the second pen tip 12. Since the second pen tip 12 has a different magnetism than the first pen tip 11, the panel 9 can define a different pen color. The second pen tip 12 produces a pen color similar to the second color ring 2316 corresponding to the second transparent display window 14, such as red, but not limited to this. When a different pen color is needed, press the button 232 of the sliding component 23 to the first position. The first magnetic magnet 24 attracts the first magnet 21, strengthening the magnetism of the first magnet 21. Therefore, the panel 9 can define another different pen color. The stylus 100 switches to writing with the first pen tip 11, which produces a pen color similar to the third color ring 2317 corresponding to the first transparent display window 13, such as blue, but not limited to this. Finally, to use a fourth pen color, press the button 232 of the sliding component 23 to the second position. The second magnetic magnet 25 attracts the second magnet 22, strengthening the magnetism of the second magnet 22. Therefore, the panel 9 can define another different pen color. The stylus 100 switches to writing with the second pen tip 12, which produces a pen color similar to the fourth color ring 2318 corresponding to the second transparent display window 14, such as green, but not limited to this.

[0029] The stylus 100 of this embodiment can also be implemented as follows, depending on the requirements: the magnetic force generating device 2 only has the first magnet 21 and the second magnet 22. The magnetic force generating device 2 is configured to generate two different magnetic states for the pen 1, namely the first magnetic state and the second magnetic state. The magnetic force generating device 2 includes a first color ring 2315 and a second color ring 2316 corresponding to the first transparent display window 13 and the second transparent display window 14, respectively. The first color ring 2315 and the second color ring 2316 are different colors and are used to represent the pen marks that the pen 1 can produce in the first magnetic state and the second magnetic state, respectively. The polarity of the first magnet 21 near the first pen tip 11 is different from the polarity of the second magnet 22 near the second pen tip 12. For example, the first magnet 21 near the first pen tip 11 is the N pole, while the second magnet 22 near the second pen tip 12 is the S pole.

[0030] Referring to Figures 1 to 4, the stylus 100 of this embodiment can also be implemented as follows, depending on the requirements: the pen body 1 includes a pen tip 11a, the magnetic force generating device 2 includes a magnet 21a disposed within the accommodating space 10 and adjacent to the pen tip 11a, a sliding component 23 slidably connected to the pen body 1, and an adsorption magnet 24a disposed within the sliding component 23 and located within the accommodating space 10 and facing the magnet 21a. The sliding component 23 can be operated to slide relative to the pen body 1 to cause the adsorption magnet 24a to adsorb onto or move away from the magnet 21a. When the adsorption magnet 24a moves away from the magnet 21a, the pen body 1 is in one of the magnetic states. When the adsorption magnet 24a adsorbs onto the magnet 21a, the pen body 1 is in the other magnetic state. The user can determine the magnetic strength of the magnet 21a by moving the sliding component 23, so that the pen body 1 produces different pen marks.

[0031] In summary, the stylus 100, through the magnetic force generating device 2, enables the pen barrel 1 to generate at least two different magnetic states, allowing for different pen colors to be produced depending on the magnetic state during use. Thus, using the same stylus 100 can achieve the effect of multiple pen colors. Therefore, the purpose of this invention is indeed achieved.
