Abstract

An electronic device is provided. The electronic device includes a main body, and a handwritten pen. The main body includes a plurality of triggers, a storage unit, a plurality of power-consuming modules, a pen socket for receiving the handwritten pen, a power supply controlling module, and a power supply module. The storage unit is configured to store a relationship table, which records a relationship between the triggers and the power-consuming modules. The pen includes a body. A spud leadis protruded from the circumference surface of the body. When one or more triggers have been triggered by the spud lead, the power supply controlling module identifies the triggered trigger, accesses the relationship table, and controls the power supply module to supply power to the power consuming module corresponding to the triggered triggers.

Description

Electronic device with stylus

The present invention relates to an electronic device, and more particularly to an electronic device having a stylus.

In general electronic devices, such as mobile phones, a plurality of modules, such as a Bluetooth module and a player module, are disposed on the main board. The above-mentioned modules have different power consumption levels.

In general, when the battery on the electronic device supplies power to the electronic device, all of the modules on the electronic device are directly powered. However, if the battery power on the electronic device is insufficient, if all the modules on the electronic device continue to be powered, the module may not continue to work due to insufficient power. Therefore, it is necessary to provide an electronic device that can selectively supply power to some modules on the electronic device according to the needs of the user, so that the power on the battery can be reasonably utilized.

It is a primary object of the present invention to provide an electronic device having a stylus that selectively supplies power to a power consuming module on an electronic device using a stylus.

The invention provides an electronic device with a stylus pen, comprising a main board and a stylus pen; the main board comprises a plurality of triggers, a memory body, a plurality of power consumption modules, and a pen a power supply control module, and a power supply module, the pen holder is configured to receive the stylus, and the memory stores a relationship table, wherein the relationship table records a correspondence between the trigger and the power consumption module; The pen includes a core having a protruding positioning post formed on a circumferential surface thereof; the power supply control is triggered when one or more of the plurality of triggers are triggered by a positioning post of the stylus inserted into the pen holder The module recognizes the triggered trigger, reads the relationship table in the memory, and controls the power supply module to supply power to the power consumption module corresponding to the triggered trigger.

The electronic device with the stylus of the invention selectively supplies power to the power consumption module on the electronic device by using the stylus, so that the power on the battery is reasonably utilized.

Please refer to FIG. 1 and FIG. 2 , which are perspective views of an electronic device 1 having a stylus according to the present invention. In the present embodiment, the electronic device 1 is a mobile phone. The electronic device 1 includes a main board 20 and a stylus pen 40. The main board 20 includes a plurality of triggers 31, a memory 32, a plurality of power consumption modules 34, a set of 35, a power supply control module 36 and a power supply module 37. The pen holder 35 is for accommodating the stylus pen 40. The power supply module 37 is used to supply power to the power consumption module 34.

The memory 32 stores a relationship table that records the correspondence between the flip-flop 31 and the power consumption module 34. The number of the triggers can be set according to the number of the power consumption modules 34.

Referring to FIG. 3 at the same time, the stylus 40 includes a refill portion 41. The core portion 41 has a cylindrical shape, and its circumferential surface is provided with at least one elastic rotating ring 42. A circumferential positioning surface 43 is formed on the circumferential surface of the rotating ring. In the present embodiment, the number of the rotating rings can be set as needed.

A plurality of through holes 36 are formed in the pen holder 35. The trigger 31 is inserted into the pen holder 35 through the through hole 36.

As shown in FIG. 4, when one or more of the plurality of flip-flops 31 inserted into the pen holder 35 are triggered by the positioning post 43 of the stylus inserted into the pen holder, the power supply control module 36 recognizes the triggered trigger 31. And reading the relationship table in the memory 32, controlling the power supply module 37 to supply power to the power consumption module 34 corresponding to the triggered trigger 31; for the trigger that is not triggered, the power supply control module 36 reads the relationship table, and controls the power supply module 37 not to supply power to the power consumption module corresponding to the trigger that is not triggered. In the present embodiment, the trigger 31 is a pressure sensor, but the trigger 31 is not limited thereto. For example, in other embodiments, the trigger 31 may be a trigger switch or the like.

When the stylus 40 is not inserted into the pen holder 35, or is inserted into the pen holder, but does not trigger any of the triggers 31, that is, the power supply control module 36 does not recognize the triggered trigger, the power supply The control module 36 sends a signal to the power supply module 37 to control the power supply module 37 to supply power to all of the power consumption modules.

It can be understood that in the present invention, the rotating ring 42 provided on the stylus pen 40 can be inelastic, and the positioning post 43 protruding from the circumferential surface of the rotating ring is elastic.
