Abstract

A stylus structure includes a main body module, a control module, a modulation module, and a cover module. The main body module includes a stylus case unit and a movable unit. The control module includes a process unit and a transmission unit. The modulation module includes multiple sensing units. The cover module includes a stylus cover unit and multiple button units. When an outer opening of the movable unit corresponds to an inner opening of the stylus case unit and the transmission unit electrically connects an external power supply terminal, the transmission unit transmits power from the external power supply terminal to the process unit. When the sensing unit is pressed against a corresponding button unit, a sensing signal is generated by the sensing unit and transmitted to the process unit. The process unit according to the sensing signal sends a color signal to an external electronic device.

First claim

What is claimed is:

1. A stylus structure, comprising:
a main body module including:
a stylus case unit having an accommodating space formed therein, an inner opening being in spatial communication with the accommodating space formed on a body of the stylus case unit, a touch control member disposed at an end of the stylus case unit, and a supportive part disposed at another end of the stylus case unit; and
a movable unit movably sleeved on the stylus case unit, wherein an outer opening is formed on the movable unit, and the inner opening is exposed from the outer opening or covered by the movable unit through a rotation of the movable unit;

a control module located in the accommodating space including a process unit and a transmission unit, wherein the process unit is communicatively connected to at least one external electronic device, and the transmission unit is electrically connected to the process unit and corresponds to the inner opening;
a modulation module wherein an end of the modulation module is electrically connected to the process unit, and another end of the modulation module is sleeved on the supportive part and includes a plurality of sensing units; and
a cover module including a stylus cover unit and a plurality of button units, wherein the stylus cover unit is detachably sleeved on the stylus case unit and has a plurality of through holes through a body of the stylus cover unit, and wherein each one of the button units is movably disposed at a corresponding through hole, and the plurality of button units correspond to the plurality of sensing units;
wherein, when the outer opening corresponds to the inner opening and the transmission unit is electrically connected to an external power supply terminal, the transmission unit transmits an electrical power supplied by the external power supply terminal to the process unit, and wherein when one of the button units is pressed against a corresponding one of the sensing units, the corresponding sensing unit generates a sensing signal and transmits the sensing signal to the process unit, and a color signal is sent to at least one of the external electronic devices by the process unit according to the sensing signal.

2. The stylus structure according to claim 1 , wherein the stylus case unit includes a upper body frame and a lower body frame, wherein the upper body frame and the lower body frame are detachably jointed together and form the accommodating space therebetween, the touch control member is located at an end of the upper body frame and at an end of the lower body frame, and the supportive part is disposed on another end of the lower body frame, and wherein the movable unit is movably sleeved on the upper body frame and the lower body frame, and the stylus cover unit is detachably sleeved on the upper body frame and the lower body frame.

3. The stylus structure according to claim 2 , wherein stylus case unit further includes a stylus cap member detachably sleeved on the upper body frame and the lower body frame.

4. The stylus structure according to claim 1 , wherein the another end of the modulation module has a positioning part detachably sleeved on the supportive part, and the plurality of sensing units are disposed on the positioning part.

5. The stylus structure according to claim 4 , wherein a shape of the supportive part is a polygonal column or circular cylinder, and the positioning part corresponds to the shape of the supportive part.

6. The stylus structure according to claim 1 , wherein the process unit generates different color signals according to the sensing signal generated by different ones of the sensing units.

7. The stylus structure according to claim 1 , wherein the modulation module has a plurality of light emitting units corresponding to each one of the sensing units, the plurality of button units are made by a transparent material, and each one of the light emitting units emits light when being pressed by the corresponding sensing unit.

8. The stylus structure according to claim 1 , further comprising a power module located in the accommodating space, wherein the power module is electrically connected to the process unit or the transmission unit and supplies power for the process unit, and wherein the transmission unit transmits the electrical power supplied by the external power supply terminal to the power module.

9. The stylus structure according to claim 8 , wherein the control module further includes a display unit exposed from the stylus case unit and electrically connected to the process unit, and a display message is generated by the display unit when the process unit is communicatively connected to at least one of the external electronic devices or the transmission unit transmits the electrical power to the power module.

10. The stylus structure according to claim 1 , wherein the control module further includes a communication unit electrically connected to the process unit, and wherein the color signal is sent to at least one of the external electronic devices by the process unit through the communication unit.
