In an embodiment of the present invention, the controller, (kbL includes a basic input output system (BI〇S) U, and a keyboard control_there is a k2 body=system: this:: connection. Basic input and output system..A^ The software program is used to instruct the keyboard controller 12 to perform the detection of the remaining power of the module 110 of the cycle to continuously obtain the information of the battery. The keyboard controller 12 can also be replaced by a microcontroller (MCU). The quantity indicating module 20 is electrically connected to the control module 1 〇. After the keyboard and the controller 12 obtain the power information, the keyboard control ϋ 12 converts the obtained power amount information into a corresponding pulse width modulation signal ( PWM) 'and transmitted to the power indicator module 2〇, at this time, the power indicator module 20 can indicate the remaining power corresponding to the current battery module 110 according to the pulse width modulation signal, for the user to confirm and confirm. Before the power supply of the portable electronic device 100 is turned off, the control module 1 of the battery power indicating system 1 of the present invention first obtains the corresponding power information from the battery module 110, and transmits the related power information to the 201140107 power indicator. mold After 20, the power-off procedure is completed, so that the remaining power detected at the time of the shutdown can be indicated after the power of the portable electronic device 10 is turned off. Please refer to FIG. 2 for the battery indicating mode of the battery power indicating system 1 of the present invention. The structure of the group 20 is exploded. As shown in FIG. 2, the power indicator module 20 includes a circuit board 21, a stepping motor 22, a gear set 23, and a meter portion 24, wherein the circuit board 21 can be used as a stepping motor 22, The base unit of the gear unit 23 and the instrument unit 24. The circuit board 21 includes a connector 211, and the connector 211 is electrically connected to the control module 10 by a cable (not shown) for receiving the transmitted power information. The stepping motor 22 is driven according to the power information. The stepping motor 22 includes a rotating shaft (not shown) and a motor gear 221 coupled to the rotating shaft, wherein the rotating shaft can be received by the control module 10 according to the power information. The pulse width modulation signal is driven to be rotated, and the motor gear 221 is also rotated as the rotation axis rotates. The stepping motor 22 can determine the amount of rotation according to the pulse width modulation signal. (ie, the number of turns) and the direction of rotation (ie, clockwise or counterclockwise) to adjust for the indicated position of the remaining power. Gear set 23 is coupled to stepper motor 22 by driving stepper motor 22 The gear set 23 includes a first gear 231 and a second gear 232. The first gear 231 further includes a first tooth portion 231a and a second tooth portion 231b. The first tooth portion 231a of the first gear 231 is The stepping motor 22 is connected such that the first tooth portion 231a and the motor gear 221 of the stepping motor 22 mesh with each other to generate an interlocking state. The second gear 232 is coupled to the second tooth portion 231b of the first gear 231 such that the second tooth portion The 231b and the second tooth 201140107 wheel 232 are coupled to each other to produce a linked state. In the present embodiment, in order to make the rotation amount corresponding to each pitch of the first gear 231 and the second gear 232 of the gear set 23 relatively accurate and easy to calculate, the first tooth portion 231a and the second tooth portion 231b are designed. The gear ratio is 3 to 1, and such that the second gear 232 rotates by one pitch to represent the hand swing of 22 degrees, but is not limited to this embodiment. The meter unit 24 includes a pointer 241 and a scale indicator plate 242. The pointer 241 is coupled to the gear set 23, and the gear unit 23 drives the pointer 241 to rotate. The scale unit 242 indicates a scale position. The pointer 241 is connected to the axis of the second gear 232, so that the pointer 241 is rotated by the second gear 232, and a power calibration line (not shown) is provided on the scale indicating plate 242 for the user to judge. At present, the scale pointed to by the pointer 241 is used to confirm the remaining amount of power of the battery module. Please refer to FIG. 3(a) and FIG. 3(b), which are schematic diagrams showing the combination of the power indicator module 20 of the battery power indicator system i of the present invention. As shown in FIG. 3(a), the power indicator module 20 first receives the power from the control module via the cable, and the power information is transmitted to the stepper through the circuit board 21. Motor 22. The stepping motor 22 will determine the amount of rotation and the direction of rotation according to the amount of power information, and then the driving shaft will start to rotate, and the motor gear 221 will also rotate accordingly. When the motor gear 221 rotates, the first gear portion 23a, which is engaged with the first gear 231, starts to rotate. Since the first tooth portion 231a of the first gear 231 is coaxial with the second tooth portion 231b, the second tooth portion 231b is also Turn together. Then, the second gear 232 that meshes with the second tooth portion 23 is also interlocked, thereby causing the pointer that is coaxial with the second gear 232 to swing. As shown in Fig. 3(b), the different scales 242a on the scale board 242 are corresponding to the positions of the pointers 241 to indicate the remaining power of the current battery module. In the embodiment, the instrument unit 24 of the power indicator module 20 is disposed on the surface of the casing of the portable electronic device 100, so that the user can directly view the instrument unit 24 to know the current state of charge without opening. The cover or housing of the portable electronic device 100 can be viewed. Further, as shown in Figures 3(a) and (b), the power indicator module 2 further includes a lighting module 25 for illuminating the meter unit 24. The illumination module 25 is composed of at least one light source 251 and at least one light guide plate 252. Each of the light guide plates 252 is disposed on a side of the instrument unit 24, and the light emitted by each light source 251 is guided to the light guide plate 252. The instrument unit 24 is provided to provide an illumination effect when the outside light is insufficient. The power indicator module 2 further includes a switch 26'. The switch 26 is electrically connected to the lighting module 25, and the switch 26 is used to turn on or off the lighting function of the lighting module 25. With the design of the present invention, the user can easily know the remaining power of the current battery module through the power indicator module, regardless of whether the portable electronic device is turned on or off, so that the user can timely charge or replace the battery module. . Referring to Figure 4, there is shown a schematic diagram of another embodiment of the battery level indicating system ia of the present invention. The embodiment is a variation of the foregoing embodiment. As shown in FIG. 4, the battery power indicating system 1& of the present invention further includes a driving module 30, and the driving module 30 is electrically connected to the control module and the power indicating mode. Group 20. Since the power information is directly transmitted through the control module 1〇, the pulse width modulation signal is susceptible to hysteresis or other interference, resulting in a pulse width modulation signal that is not stable to 201140107. The power indication is delayed, which in turn affects the indicated remaining power = motion/caused error or delay, in the control group 1G and the power g = accuracy ' is therefore in this example group 30.
