【detailed description】

FIG. 1 is a schematic block diagram of an electronic device with an uninterruptible power supply according to an embodiment of the present invention. Please refer to FIG. 1 , an electronic device 100 with an uninterruptible power supply includes a power input terminal 110 , a sub-battery module 120 , a switch module 130 , a motion sensor 140 and a control unit 150 . The control unit 150 is coupled to the switch module 130 and the motion sensor 140 , and the switch module 130 is coupled between the sub-battery module 120 and the power input terminal 110 .

In some embodiments, the electronic device 100 can be a portable electronic device such as a notebook computer, a tablet computer, or a mobile phone, which is convenient for the user to carry, but the present invention is not limited thereto.

The power input terminal 110 can be used to receive a power to maintain the operation of the electronic device 100 . Generally speaking, the electronic device 100 is maintained by the power provided by the main battery module 200 in a general use state (normal state). Wherein, the main battery module 200 can provide the stored power to the electronic device 100 through the power input terminal 110 through the contact between its power supply electrode (not shown) and the power input terminal 110 to maintain the operation of the electronic device. Here, the electronic device 100 is provided with a battery placement part (not shown), and the main battery module 200 is detachably combined in the battery placement part (not shown) of the electronic device 100, so as to facilitate the user to replace the main battery module. battery module 200 .

In some embodiments, the main battery module 200 can be a lithium battery or a rechargeable lithium-ion battery, etc., but the invention is not limited thereto.

The sub-battery module 120 is used for storing backup power. Here, the sub-battery module 120 can be electrically connected to the power input terminal 110 through the switch module 130 when the switch module 130 is turned on, so that when the main battery module 200 cannot provide power to the electronic device 100, the sub-battery module 120 can provide power through the power input terminal 110. The input terminal 110 provides power to the electronic device 100 to maintain the operation of the electronic device. Wherein, the line between the sub-battery module 120 and the power input terminal 110 via the switch module 130 is the power supply path of the sub-battery module 120 . Here, the power supply path of the sub-battery module 120 can be established by turning on the switch module 130 and cut off by turning off the switch module 130 . In other words, when the power supply path of the sub-battery module 120 is established, the sub-battery module 120 can provide the stored power to the electronic device 100 . When the power supply path of the sub-battery module 120 is cut off, the power stored in the sub-battery module 120 stops outputting to the electronic device 100 . Here, the sub-battery module 120 may be an independently provided battery and built in the electronic device 100 , for example, mounted on a circuit board inside the electronic device 100 .

Generally speaking, in order to avoid the weight of the electronic device 100 from being too heavy, the volume of the sub-battery module 120 built in the electronic device 100 should not be too large. Therefore, the capacity of the sub-battery module 120 is smaller than that of the main battery module 200 . In some embodiments, the sub-battery module 120 may be a mercury battery or a capacitor module, but the invention is not limited thereto.

The movement sensor 140 is used to sense the movement of the electronic device 100 and generate a corresponding detection result D1. In some embodiments, the motion sensor 140 can be a gravity sensing unit (G-sensor), a gyroscope (gyroscope) or a combination thereof, and the detection result D1 can be gravity information of the electronic device 100, attitude information, or combination. Wherein, the gravity information may cover the gravitational acceleration value (ie, G value), moving speed and displacement of the electronic device 100, and the attitude information may cover the azimuth and/or angular velocity of the electronic device 100, but the present invention is not This is the limit.

The control unit 150 is used for reading the detection result D1 generated by the motion sensor 140, and comparing the detection result D1 with a preset movement condition to determine whether the detection result D1 meets the movement condition. In some embodiments, the movement condition can be that the detection result D1 is greater than the corresponding threshold (for example, the G value is greater than 0.2 and/or the angular velocity of any axis in the X-axis, Y-axis, and Z-axis is greater than 5°/sec, etc.) , or the detection result D1 exceeds the corresponding range, but the present invention is not limited thereto, and the moving condition can be preset according to the needs of the user.

When the control unit 150 determines that the detection result D1 meets the movement condition (for example, the detection result D1 is greater than the corresponding threshold value), the control unit 150 determines that the electronic device 100 is in an unsafe state at this time, such as in a rapid state such as throwing or falling. , violent movement, and the control unit 150 generates an opening signal S1 to turn on the switch module 130 to open the power supply path of the sub-battery module 120 . Therefore, even if the electronic device 100 is in an unsafe state (such as throwing, falling, etc.) and the main battery module 200 comes out of the battery placement part, the electronic device 100 can still be powered by the power provided by the sub-battery module 120. Maintain operation without momentary shutdown. Conversely, when the control unit 150 determines that the detection result D1 does not meet the moving condition, it means that the control unit 150 determines that the electronic device 100 is in a safe state at this time, and the control unit 150 does not generate the start signal S1.

Since the motion sensor 140 continuously senses the electronic device 100 , for example, re-sensing every 1 second, and generates a corresponding detection result D1 after each sensing. Therefore, the control unit 150 can sequentially determine whether the movement condition is met according to each detection result D1 generated by the movement sensor 140 . When the control unit 150 determines that the movement condition is not met according to the next detection result D1 generated by the motion sensor 140 after the switch module 130 is turned on by generating the start signal S1, it means that the control unit 150 determines that the electronic device 100 is at this time The unsafe state has changed to the safe state. Therefore, at this time, the control unit 150 can generate a shutdown signal S2 to disconnect the switch module 130 , so as to cut off the power supply path from the sub-battery module 120 to the power input terminal 110 .

In one embodiment, the control unit 150 may immediately output the shutdown signal S2 to turn off the switch module 130 to cut off the power supply path of the sub-battery module 120 when determining that the moving condition is not met. In another embodiment, the control unit 150 can delay for a predetermined time, such as 30 seconds or one minute, and then generate the shutdown signal S2 to disconnect the switch module 130 to cut off the power supply path of the sub-battery module 120, so that when the main When the battery module 200 is removed from the electronic device 100, as long as the user can reassemble the main battery module 200 into the battery placement part of the electronic device 100 within the predetermined time, the electronic device 100 will not be shut down instantaneously. .

In some embodiments, the control unit 150 can be an embedded controller (EC), a SoC (System on aChip) chip, a central processing unit (CPU) or a microcontroller (MCU), etc., but the invention is not limited thereto.

FIG. 2 is a schematic block diagram of an electronic device with an uninterruptible power supply according to another embodiment of the present invention. Please refer to FIG. 2 , the electronic device with uninterruptible power supply 100 may further include a power supply detection unit 160 , and the power supply detection unit 160 is coupled to the power input terminal 110 and the control unit 150 .

The power supply detection unit 160 can be used to detect whether the power input terminal 110 has received the power supplied by the main battery module 200, and the power supply detection unit 160 can detect that the power input terminal 110 has received the power supplied by the main battery module 200 When the electric power is low, the shutdown signal S2 is immediately generated to disconnect the switch module 130 to cut off the power supply path of the sub-battery module 120 . On the contrary, when the power supply detection unit 160 does not detect that the power input terminal 110 receives the power supplied by the main battery module 200 , the power supply detection unit 160 does not generate the shutdown signal S2 .

In one embodiment, when the power supply detection unit 160 detects that the power input terminal 110 has received the power supplied by the main battery module 200, it delays for a predetermined time, such as 30 seconds or one minute, and then generates a shutdown signal. S2 Turn off the switch module 130 to cut off the power supply path of the sub-battery module 120 . This is to avoid the power supply path of the sub-battery module 120 after the electronic device 100 meets the moving conditions and before the main battery module 200 is released from the electronic device 100 (for example, the electronic device 100 is still in a falling state and before a collision occurs). It has been cut off, and then the subsequent electronic device 100 will be shut down instantaneously when the main battery module 200 is pulled out (for example, the main battery module 200 is pulled out due to a collision of the electronic device 100 ). In this way, as long as the main battery module 200 of the electronic device 100 continues to supply power after the predetermined time (for example, the electronic device 100 has ended the unsafe state within the predetermined time and the main battery module 200 that has been removed has been installed back into the electronic device 100 , or the electronic device 100 has ended the unsafe state within the predetermined time and the battery module 200 has not come out), the electronic device 100 will not be shut down instantaneously.

In one embodiment, after the power supply detection unit 160 generates the shutdown signal S2, it can output the shutdown signal S2 to the control unit 150, so that the control unit 150 can turn off the switch module 130 according to the shutdown signal S2. In other words, the control unit 150 is mainly responsible for the control of the switch module 130 at this time, and the shutdown signal S2 generated by the power supply detection unit 160 can be used to trigger the control unit 150 to control the switch module 130 accordingly. However, the present invention is not limited thereto.

In another embodiment, the shutdown signal S2 generated by the power supply detection unit 160 can be directly output to the switch module 130 to cut off the power supply path from the sub-battery module 120 to the power input terminal 110 . In other words, the control of the switch module 130 is jointly managed by the control unit 150 and the power supply detection unit 160 , and the switch module 130 can perform corresponding actions corresponding to the received open signal S1 and close signal S2 .

In some embodiments, the power supply detecting module 160 starts to detect after the control unit 150 generates the turn-on signal S1 to turn on the switch module 130 , but the present invention is not limited thereto. In some other embodiments, the power supply detection module 160 determines that the electronic device 100 meets the mobile condition according to the detection result D1, and the control unit 150 then determines that the electronic device 100 has been moved according to another detection result D1. Detection starts when the movement condition is not met.

FIG. 3 is a flow chart of an uninterruptible power supply control method according to an embodiment of the present invention. Please refer to FIG. 1 and FIG. 3 , in one embodiment, the control unit 150 can read the detection result D1 of the motion sensor 140 of the electronic device 100 (step S11 ). Afterwards, the control unit 150 may determine whether the detection result D1 meets the movement condition (step S12 ). If the control unit 150 determines that the detection result D1 meets the moving condition, the control unit 150 may open the power supply path of the sub-battery module 120 of the electronic device 100 (step S13a). On the contrary, if the control unit 150 determines that the detection result D1 does not meet the moving condition, the control unit 150 may close the power supply path of the sub-battery module 120 of the electronic device 100 (step S13b).

Herein, the electronic device 100 is powered by the main battery module 200 that can be assembled in its battery placement part in the use state (normal state). The sub-battery module 120 is built in the electronic device 100 and can be connected in parallel with the main battery module 200 via the switch module 130 . Here, the line from the sub-battery module 120 to the power input terminal 110 via the switch module 130 is the power supply path of the sub-battery module 120 .

In an embodiment of step S11 , the motion sensor 140 continuously senses the electronic device 100 or senses after a preset time interval, and generates a corresponding detection result D1 . The control unit 150 can continuously read each detection result D1 generated by the motion sensor 140 sequentially, or read the detection result D1 generated by the motion sensor 140 after a processing time interval each time.

In an embodiment of step S12 , the control unit 150 can compare the read detection result D1 with the preset moving condition sequentially, and judge whether the detected result D1 matches the moving condition accordingly. In some embodiments, the movement condition can be that the detection result D1 is greater than the corresponding threshold, for example, the G value is greater than 0.2 and/or the angular velocity of any of the X-axis, Y-axis, and Z-axis is greater than 5°/sec. The control unit 150 can determine whether the electronic device 100 is in an unsafe state according to the comparison result of the detection result D1 and the moving condition, that is, whether it is in a state of rapid and violent movement such as throwing or falling.

When the control unit 150 determines that the detection result D1 matches the movement condition, it means that the control unit 150 determines that the electronic device 100 is in an unsafe state at this time. In the case of momentary shutdown, step S13 a can be executed continuously to open the power supply path of the sub-battery module 120 to maintain the operation of the electronic device 100 . At this time, the control unit 150 generates a start signal S1 to turn on the switch module 130 to turn on the power supply path of the sub-battery module 120 .

Conversely, when the control unit 150 determines that the detection result D1 does not match the moving condition, it means that the control unit 150 determines that the electronic device 100 is in a safe state at this time, and there is no need to open the power supply path of the sub-battery module 120, so the steps can be continued S13b. At this time, the control unit 150 generates a shutdown signal S2 to disconnect the switch module 130 to cut off the power supply path from the sub-battery module 120 to the power input terminal 110 . In other words, when the control unit 150 determines that the detection result D1 does not match the moving condition, the sub-battery module 120 does not output power at this time.

In an embodiment of step S13b, if the switch module 130 is already in the off state, the control unit 150 does not need to generate the close signal S2 to the switch module 130 again. On the contrary, if the switch module 130 was originally in the on state (that is, the power supply path of the sub-battery module 120 was turned on by executing step S13a during the previous round of power control), the control unit 150 needs to turn off The signal S2 turns off the switch module 130 to cut off the power supply path of the sub-battery module 120 .

In one embodiment, the control unit 150 may delay generating the shutdown signal S2 after a predetermined time. In another embodiment, the control unit 150 may generate the shutdown signal S2 when it is determined that the detection result D1 does not match the movement condition. After step S13a or step S13b is completed, both can return to step S11 to perform another round of power control again.

FIG. 4 is a flowchart of an uninterruptible power supply control method according to another embodiment of the present invention. Please refer to FIG. 2 and FIG. 4 , in one embodiment, the control unit 150 can read the detection result D1 of the motion sensor 140 of the electronic device 100 (step S21 ). Afterwards, the control unit 150 may determine whether the detection result D1 meets the moving condition (step S22 ). If the control unit 150 determines that the detection result D1 does not meet the moving condition, the control unit 150 may close the power supply path of the sub-battery module 120 of the electronic device 100 (step S23b). On the contrary, if the control unit 150 determines that the detection result D1 meets the moving condition, the control unit 150 can open the power supply path of the sub-battery module 120 of the electronic device 100 (step S23a), and the power supply detection unit 160 can start to detect the main battery module 200 whether to supply power (step S24). When the power supply detection unit 160 detects that the main battery module 200 has power supply, the power supply detection unit 160 can generate a shutdown signal S2, and continue to perform step S23b to close the power supply path of the sub-battery module 120 . Conversely, when the power supply detection unit 160 detects that the main battery module 200 is not supplying power, then repeat step S24 until the power supply detection unit 160 detects that the main battery module 200 has power supply and generates a shutdown signal S2, the power supply detection unit 160 to stop detection.

Here, step S21 , step S22 , step S23 a and step S23 b are substantially the same as step S11 , step S12 , step S13 a and step S13 b , so details are not repeated here.

To sum up, the uninterruptible power supply control method and the electronic device with uninterruptible power supply according to an embodiment of the present invention can open the power supply path of the sub-battery module when it is judged that the detection result of the movement sensor meets the movement condition, So that even if the electronic device cannot receive the power supplied by the main battery module due to an unsafe state (such as throwing, falling, etc.), it can still receive the required power through the power supply circuit of the sub-battery module. Maintain the normal operation of electronic devices, thereby improving subsequent information loss, abnormalities, and damages.
