Description

TECHNICAL FIELD

[0001] The present application relates to a stylus, in particular to a stylus device capable of improving signal strength and saving power. BACKGROUND

[0002] With the development of technology, electronic products are becoming more and more advanced. Electronic devices with touch screens, such as digitizers, tablet computers, smart phones, and other touch electronic devices, have become one of the trends and mainstream of today's technology. When operating, most users directly click and slide on the touch screen with their fingers. However, when writing, drawing, or performing more detailed operations on the touch screen for a long time, fingers are obviously inconvenient for operation. Therefore, most users purchase styluses to operate the touch screen.

[0003] In order to increase the line variation generated by the stylus, some touch electronic devices today can detect multiple signals emitted by the stylus during operation, calculate the tilt angle of the stylus, and thus generate visual changes in line thickness.

[0004] However, the design of most current styluses makes the signals received by the touch electronic device unstable, and the stylus also consumes more power.

[0005] Therefore, how to overcome the above-mentioned defects by improvement has become one of the important issues that the field wants to solve. SUMMARY

[0006] The technical problem to be solved by the present application is to provide a stylus device to overcome the deficiencies of the prior art.

[0007] To solve the above technical problems, one of the technical solutions adopted by the present application is to provide a stylus device, comprising a pen body module, a first transmitting module, a transceiving module, a second transmitting module, and a processing module. The first transmitting module is arranged on the pen body module. The transceiving module is arranged on the pen body module. The second transmitting module is arranged on the pen body module and adjacent to the transceiving module. The processing module comprises a switch unit and a control unit. The switch unit is connected to the transceiving module. The control unit is arranged on the pen body module and connected to the first transmitting module, the second transmitting module, and the switch unit. The control unit selectively controls the first transmitting module to output a first sensing signal or controls the second transmitting module to transmit a second sensing signal. The control unit selectively controls the switch unit to switch to a floating state. When the control unit is in a first transmitting mode, the control unit controls the switch unit to switch to the floating state and controls the second transmitting module to transmit the second sensing signal. The transceiving module and the second transmitting module are coupled to each other to sense and transmit the second sensing signal.

[0008] One of the beneficial effects of the present application is that the stylus device provided by the present application can improve the strength of the signal transmitted by the stylus device and reduce the power consumption of the stylus device by the technical solution of "the first transmitting module is arranged on the pen body module. The transceiving module is arranged on the pen body module. The second transmitting module is arranged on the pen body module and adjacent to the transceiving module.

[0021] Please refer to Figures 1 to 6, respectively, are a perspective view, an exploded view, a partial structure view, a partial cross-sectional view, a first functional block diagram, and a second functional block diagram of the stylus device of the first embodiment of the present application. As shown, the first embodiment of the present application provides a stylus device D, which includes a body module 1, a first transmitting module 2, a transceiving module 3, a second transmitting module 4, and a processing module 5. In cooperation Figure 1 As shown, the stylus device D of the present application can be a capacitive stylus or other types of stylus, and the stylus device D can be used in cooperation with a touch electronic device (not shown in the figure; the touch electronic device can be, for example, a digitizer, a tablet computer, a smart phone, etc., but is not limited thereto).

[0022] In cooperation Figure 1 and Figure 4 As shown, the body module 1 of the present application can be the main structure of the stylus device D. For example, the body module 1 can include a first housing unit 10, a second housing unit 11, and a refill unit 12. The second housing unit 11 is detachably connected to the first housing unit 10, and a first accommodating space P1 is defined between the second housing unit 11 and the first housing unit 10, which can be used to accommodate the processing module 5. The refill unit 12 is disposed at one end of the second housing unit 11 and adjacent to one end of the first housing unit 10, and the refill unit 12 is connected to the first transmitting module 2.

[0023] Next, in cooperation Figure 2 and Figure 5 As shown, the first transmitting module 2 of the present application is disposed in the body module 1. For example, the first transmitting module 2 can include a first driving unit 20 and a first elevated voltage unit 21. The first driving unit 20 is electrically connected to the control unit 51 of the processing module 5. The first elevated voltage unit 21 is connected to the refill unit 12 and the first driving unit 20.

[0024] Next, in cooperation Figures 2 to 5 As shown, the transceiving module 3 of the present application can be disposed in the body module 1. For example, the transceiving module 3 can be sleeved at one end of the body module 1 and surround the refill unit 12. Further, the transceiving module 3 can be a ring-shaped shielding structure, for example, a hollow conical structure, but is not limited thereto, and the transceiving module 3 can be a sleeve element made of metal or plastic, but is not limited thereto. The transceiving module 3 can be sleeved at one end of the second housing unit 11 and adjacent to one end of the first housing unit 10, and the transceiving module 3 surrounds the refill unit 12.

[0025] Next, in cooperation Figures 2 to 5As shown, the second transmitting module 4 of the present application is arranged in the pen body module 1 and adjacent to the transceiving module 3. For example, the second transmitting module 4 can include a transmitting ring unit 40, a second driving unit 41 and a second elevated voltage unit 42. The transmitting ring unit 40 can be a hollow conical structure and can be a sleeve element made of metal or plastic, but is not limited thereto. The transmitting ring unit 40 can be sleeved on one end of the second housing unit 11 and adjacent to one end of the first housing unit 10, the transmitting ring unit 40 covers part of the transceiving module 3, and the transmitting ring unit 40 does not contact the transceiving module 3; that is, there is a distance or gap between the transmitting ring unit 40 and the transceiving module 3. The second driving unit 41 is electrically connected to the control unit 51 of the processing module 5. The second elevated voltage unit 42 is connected to the transmitting ring unit 40 and the second driving unit 41.

[0026] Next, as shown in Figure 2 and Figure 5 As shown, the processing module 5 can include a switch unit 50 and a control unit 51. The switch unit 50 is connected to the transceiving module 3. The control unit 51 is arranged in the first accommodating space P1 of the pen body module 1 and is connected to the first transmitting module 2, the second transmitting module 4 and the switch unit 50. The control unit 51 selectively controls the first transmitting module 2 to output the first sensing signal or controls the second transmitting module 4 to transmit the second sensing signal, and the control unit 51 selectively controls the switch unit 50 to switch to a floating state. For example, the switch unit 50 can be any switching element, and the control unit 51 can be a processor or a circuit board with control and processing functions, but is not limited thereto. The switch unit 50 can include a first contact 500 and a second contact 501. The first contact 500 is connected to the transceiving module 3. The second contact 501 is connected to the ground end 6. The control unit 51 can be arranged in the first accommodating space P1 between the first housing unit 10 and the second housing unit 11. Moreover, the control unit 51 can selectively control the first driving unit 20 to transmit the first sensing signal to the first elevated voltage unit 21 or control the second driving unit 41 to transmit the second sensing signal to the second elevated voltage unit 42 according to software settings or control signals. When the control unit 51 drives the first driving unit 20 to transmit the first sensing signal to the first elevated voltage unit 21, the first elevated voltage unit 21 can boost the first sensing signal and emit the first sensing signal outward through the pen core unit 12; when the control unit 51 drives the second driving unit 41 to transmit the second sensing signal to the second elevated voltage unit 42, the second elevated voltage unit 42 can boost the second sensing signal and emit the second sensing signal outward through the transmitting ring unit 40.

[0027] Therefore, when the control unit 51 is in the first transmission mode, the control unit 51 controls the switch unit 50 to switch to a floating state, and controls the second transmission module 4 to transmit the second induction signal, and the transceiving module 3 to be coupled with the second transmission module 4 to induce the second induction signal. For example, as shown in FIG. 1, when the touch pen device D is in the first transmission mode, the control unit 51 controls the switch unit 50 to switch to a floating state in which the first contact point 500 is not connected with the second contact point 501, and controls the second drive unit 41 to transmit the second induction signal to the second elevated voltage unit 42, and the transmission ring unit 40 to transmit the second induction signal outwardly. At this time, the transceiving module 3 can be coupled with the second transmission module 4 to induce and transmit the second induction signal together. Figures 2 to 5

[0028] It is worth noting that in other embodiments, when the control unit 51 is in the first transmission mode, the control unit 51 can also control the switch unit 50 to switch to a state in which the transceiving module 3 is connected with the signal adjustment unit 52. For example, as shown in FIG. 2, when the touch pen device D is in the first transmission mode, the control unit 51 can control the switch unit 50 to switch to a state in which the first contact point 500 is connected with the third contact point 502, and the third contact point 502 is connected with the signal adjustment unit 52. Then, when the control unit 51 controls the second drive unit 41 to transmit the second induction signal to the second elevated voltage unit 42, the second elevated voltage unit 42 can transmit the second induction signal outwardly by using the transmission ring unit 40, and the transceiving module 3 can be coupled with the second transmission module 4 to induce and transmit the second induction signal together. In the first transmission mode in which the first contact point 500 is connected with the third contact point 502, the transceiving module 3 can be in a state in which no external signal is received, or no external signal is received by the transceiving module 3. Figures 2 to 4 Figure 7

[0029] Thus, by the above technical solutions, the touch pen device D of the present application can transmit the second induction signal by using the transceiving module 3, so that the touch electronic device can receive a signal with strong induction, and the power consumption of the touch pen device D can be reduced.

[0030] Further, when the control unit 51 is in the second transmission mode, the control unit 51 controls the switch unit 50 to switch to a ground state, and controls the first transmission module 2 to output the first induction signal. When the switch unit 50 is in the ground state, the switch unit 50 connects the transceiving module 3 with a ground terminal 6. For example, as shown in FIG. 3, when the touch pen device D is in the second transmission mode, the control unit 51 controls the switch unit 50 to switch to a ground state in which the first contact point 500 is connected with the second contact point 501, and the second contact point 501 is connected with the ground terminal 6. Then, when the control unit 51 controls the first drive unit 31 to transmit the first induction signal to the first elevated voltage unit 32, the first elevated voltage unit 32 can transmit the first induction signal outwardly by using the transmission ring unit 40, and the transceiving module 3 can be coupled with the first transmission module 2 to induce and transmit the first induction signal together. Figures 2 to 6 ​​​As shown, when the stylus device D is in the second transmission mode, the control unit 51 can control the switch unit 50 to switch to a state in which the first contact point 500 is connected to the second contact point 501 and is grounded; and the control unit 51 drives the first driving unit 20 to transmit the first induction signal to the first elevated voltage unit 21, and the control unit 51 drives the pen core unit 12 to transmit the first induction signal outward.

[0031] Further, the body module 1 can further include a sheath element 13, a tip cover element 14, and a tail cover element 15. The sheath element 13 is connected to the first housing unit 10 and the second housing unit 11. Figure 1 Figure 2 As shown, the sheath element 13 can have a second accommodation space P2 for accommodating the first housing unit 10 and the second housing unit 11. The tip cover element 14 is detachably connected to one end of the sheath element 13 and covers the transceiver module 3 and the transmission ring unit 40. The tail cover element 15 is detachably connected to the other end of the sheath element 13, and the tip cover element 14 and the tail cover element 15 can be respectively arranged at the two ends of the sheath element 13.

[0032] However, the above-mentioned example is only one possible embodiment and is not intended to limit the present application.

[0033] Second embodiment

[0034] Please refer to Figure 7 , which is a functional block diagram of the stylus device of the second embodiment of the present application, and please refer to Figures 1 to 6 . As shown, the stylus device D of the present embodiment is substantially similar to the stylus device D of the first embodiment described above, and thus the arrangement or operation of the same elements will not be described here. In the present embodiment, the processing module 5 can further include a signal adjustment unit 52 connected to the control unit 51 and the switch unit 50; wherein when the control unit 51 is in the receiving mode, the control unit 51 controls the switch unit 50 to switch to a receiving state, so that the transceiver module 3 is connected to the signal adjustment unit 52.

[0035] For example, as shown in Figure 2 and Figure 7 , the signal adjustment unit 52 can include a filter element 520, a signal amplifier element 521, and a demodulator element 522. The filter element 520 can be a filter, the signal amplifier element 521 can be a signal amplifier, and the demodulator element 522 can be a demodulator, but not limited thereto. The filter element 520 is connected to the switch unit 50. The signal amplifier element 521 is connected to the filter element 520. The demodulator element 522 is connected to the control unit 51 and the signal amplifier element 521. Furthermore, the switch unit 50 can further include a third contact point 502 connected to the signal adjustment unit 52.

[0036] ​Therefore, when the stylus device D is in the receiving mode, the control unit 51 can control the switch unit 50 to switch to the state that the first contact 500 is connected with the third contact 502. When the transceiving module 3 receives an external signal (for example, a signal emitted by a touch electronic device, but not limited to this), the transceiving module 3 can transmit the external signal to the control unit 51 through the filter element 520, the signal amplification element 521 and the demodulation element 522.

[0037] However, the above-mentioned example is only one possible embodiment and is not intended to limit the present application.

[0038] Third embodiment

[0039] Please refer to Figure 8 , the functional block diagram of the stylus device of the third embodiment of the present application, and please refer to Figures 1 to 7 . As shown in the figure, the stylus device D of the present embodiment is generally similar to the stylus device D of the above-mentioned embodiments, therefore, the same element setting or action will not be described here. In the present embodiment, when the control unit 51 is in the third transmission mode, the control unit 51 controls the switch unit 50 to switch to the conducting state, and controls the second transmission module 4 to emit the second sensing signal, and the transceiving module 3 to receive and emit the second sensing signal; wherein, when the switch unit 50 is in the conducting state, the switch unit 50 connects the second transmission module 4 and the transceiving module 3.

[0040] For example, as shown in Figure 2 and Figure 8 , the switch unit 50 of the present application can further include a fourth contact 503, which is connected with the second elevated voltage unit 42 of the second transmission module 4. Therefore, when the stylus device D is in the third transmission mode, the control unit 51 controls the switch unit 50 to switch to the state that the first contact 500 is connected with the fourth contact 503, and is in the conducting state; and the control unit 51 drives the second driving unit 41 to transmit a plurality of second sensing signals to the second elevated voltage unit 42; at this time, the second elevated voltage unit 42 can elevate the plurality of second sensing signals and transmit them to the transmission ring unit 40 and the transceiving module 3 respectively, and emit the second sensing signals outwardly by using the transmission ring unit 40 and the transceiving module 3.

[0041] However, the above-mentioned example is only one possible embodiment and is not intended to limit the present application.

[0042] It is worth mentioning that the control unit 51 of the stylus device D of the present application can switch to the first transmission mode, the second transmission mode, the receiving mode and the third transmission mode in sequence or randomly according to the preset program, but not limited to this.

The second emitting module 4 and the transceiving module 3 are coupled to each other to sense the emitted second sensing signal. The above technical solution can improve the strength of the signal emitted by the stylus device and reduce the power consumption of the stylus device.

[0045] Furthermore, the stylus device D provided by the present application can emit a first sensing signal through the first emitting module 2, receive an external signal through the transceiving module 3, and emit a second sensing signal through the second emitting module 4.
