Detailed Description

Summary of the application

With the rapid development of science and technology, electronic devices have more and more functions, and correspondingly, power consumption of the electronic devices has more and more power consumption. The power supply itself of the electronic device is often not completely powered off after the shutdown, but a relatively low current is maintained, that is, the electronic device has shutdown power consumption.

In the case where the battery level is low, the shutdown power consumption may cause the battery of the electronic device to enter an overdischarge mode. For example, when an electronic device is automatically powered off due to too low a battery power, the power consumption of the power off may cause the battery to enter an overdischarge mode for a short period of time, even to 0V.

The battery can be irreversibly damaged due to over-discharge, and the battery can be charged under the condition of over-discharge, so that the battery bulges easily, and certain potential safety hazard exists. In order to avoid over-discharge of the battery, the most common scheme in the prior art is to install a protection chip with 0V for forbidden charging on the battery protection board, namely, when the battery is over-discharged to 0V, the battery cannot be charged. However, for electronic devices with low usage, this solution requires the user to charge at regular intervals, which is inconvenient to use; and once the electronic equipment is automatically powered off due to the fact that the electric quantity is too low and a user does not charge in time, the electronic equipment cannot be charged and powered on after the battery is excessively discharged to 0V due to power consumption of power off, and only the battery can be replaced, so that waste is caused.

Based on the above, the utility model provides the power control device, the power component and the electronic device, and the technical scheme can thoroughly power off the electronic device after the electronic device is powered off, so that the power consumption of the electronic device is not existed, the situation that the battery is overdischarged is effectively avoided, the use is convenient, and the waste is not caused.

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Exemplary Power control apparatus

An embodiment of the present utility model proposes a power control apparatus, as shown in fig. 1, including:

an enable terminal a, a power terminal B, and a load terminal C. A switching circuit K is arranged between the power supply end B and the load end C, and the enabling end A is connected with the switching circuit K.

The enable terminal a is configured to receive an enable signal, and the enable signal is configured to control on and off of the switching circuit K. The power supply end B is used for being connected with a battery of the electronic equipment, and the load end C is used for being connected with an electric load of the electronic equipment. The electronic device refers to a device provided with a battery at will, and for example, the electronic device may be a notebook computer, a smart phone, a tablet computer, a smart watch, a scanning pen, a translation pen, an education tablet, and the like.

Specifically, the enable signal includes a signal that controls the switch circuit K to be turned on and a signal that controls the switch circuit K to be turned off. When the enabling signal acquired by the enabling end A is a signal for controlling the switching circuit K to be conducted, the switching circuit K is conducted, the power end B is connected with the load end C, a power circuit is formed by a battery of the electronic equipment and an electricity utilization load of the electronic equipment, and the battery of the electronic equipment can supply power to the electricity utilization load; when the enabling signal acquired by the enabling end A is a signal for controlling the switching circuit K to be turned off, the switching circuit K is turned off, the power end B and the load end C are disconnected, a power circuit cannot be formed between a battery of the electronic equipment and an electricity utilization load of the electronic equipment, the battery of the electronic equipment cannot supply power to any electricity utilization load, and the electronic equipment is thoroughly powered off.

It should be noted that, the control of the on/off of the switching circuit K after the enabling terminal a obtains the enabling signal is a conventional control method in the prior art, and the control can be obtained by those skilled in the art without performing any inventive labor, which is not described herein.

Further, in some embodiments, as shown in fig. 2, the electrical load of the electronic device includes a controller and other peripherals. Other peripheral devices include a display module, a camera module, etc., which is not limited in this embodiment. The controller is connected with an enabling end A and sends an enabling signal to the enabling end A. Specifically, the controller of the electronic device is a main control element for controlling the operation of the electronic device, and the working principle of the controller is a mature technology in the prior art, which is not described herein.

When the electronic device needs to be completely powered off, an enabling signal for controlling the switch circuit K to be turned off can be generated by the controller and sent to the enabling end A. Specifically, a trigger condition may be set according to an actual situation, where the trigger condition is used to trigger the controller to generate an enable signal that controls the switch circuit K to be turned off, and send the signal to the enable terminal a.

For example, after the electronic device receives the shutdown instruction of the user, the options of "complete shutdown" and "normal shutdown" may be popped up on the interactive interface, where "complete shutdown" indicates that the electronic device is completely powered off after shutdown, no shutdown power consumption is involved in the electronic device, and "normal shutdown" indicates that the electronic device is normally shutdown, and shutdown power consumption exists in the electronic device after shutdown. When the user selects 'complete shutdown', the trigger controller generates an enabling signal for controlling the switch circuit K to be closed, and sends the enabling signal to the enabling end A. In another example, when the voltage of the battery is detected to be smaller than the set value for a set period of time, the trigger controller generates an enable signal for controlling the switch circuit K to be turned off, and sends the signal to the enable terminal a. For example, when it is detected that the voltage of the battery is less than or equal to 3.2V for 30 seconds, the trigger controller generates an enable signal that controls the switching circuit K to be turned off, and sends the signal to the enable terminal a. In still another example, after receiving the shutdown instruction of the user, the electronic device may directly trigger the controller to generate an enable signal for controlling the switch circuit K to be turned off, and send the enable signal to the enable terminal a.

When the power supply of the load in the electronic equipment needs to be restored, an enabling signal for controlling the switch circuit K to be conducted can be generated by the controller and sent to the enabling end A. A trigger condition may be set according to an actual situation, where the trigger condition is used to trigger the controller to generate an enable signal for controlling the switch circuit K to be turned on, and send the signal to the enable terminal a.

For example, when the electronic device detects that the external power is connected, the controller may be triggered under the influence of the external power to generate an enable signal for controlling the switch circuit K to be turned on, and send the enable signal to the enable terminal a.

It should be noted that, the generation of the enabling signal by triggering the controller of the electronic device by the external signal is a conventional control method in the prior art, and the controller of the electronic device can be obtained by a person skilled in the art without performing any creative effort, which is not described herein. Moreover, the embodiment of the present utility model is not limited to the generation manner of the enable signal, and those skilled in the art may generate the enable signal in other manners in the prior art.

In some embodiments, as shown in fig. 3, the switching circuit K of the above embodiment includes a signal conversion circuit K1 and a switching control circuit K2.

The signal conversion circuit K1 is configured to perform signal conversion to convert an enable signal into a switch trigger signal. The switch trigger signal comprises an electric signal for triggering the switch control circuit K2 to be turned on or turned off, wherein if the enabling signal is a signal for controlling the switch circuit K to be turned on, the signal conversion circuit K1 converts the enabling signal into the electric signal for triggering the switch control circuit K2 to be turned on; if the enable signal is a signal for controlling the switch circuit K to be turned off, the signal conversion circuit K1 converts the enable signal into an electric signal for triggering the switch control circuit K2 to be turned off.

Specifically, the input end of the signal conversion circuit K1 is used as an enabling end A of the power supply control device and is used for being connected with a controller of the electronic device to receive an enabling signal; the output end of the signal conversion circuit K1 is connected with the enabling end of the switch control circuit K2, and the signal conversion circuit K1 sends a switch trigger signal to the switch control circuit K2 through the output end; the power end of the switch control circuit K2 is used as a power end B of the power control equipment and is used for being connected with a battery of the electronic equipment; the load end of the switch control circuit is used as the load end C of the power supply control equipment and is used for connecting the power utilization load of the electronic equipment.

When the enabling signal acquired by the signal conversion circuit K1 is a signal for controlling the switch circuit K to be turned on, the signal conversion circuit K1 converts the signal into an electric signal for triggering the switch control circuit K2 to be turned on and sends the electric signal to the switch control circuit K2, a power end and a load end of the switch control circuit K2 are turned on, a power end B is connected with the load end C, and a battery of the electronic equipment can supply power to an electric load; when the enabling signal acquired by the signal conversion circuit K1 is a signal for controlling the switch circuit K to be turned off, the signal conversion circuit K1 converts the signal into an electric signal for triggering the switch control circuit K2 to be turned off and sends the electric signal to the switch control circuit K2, the power end and the load end of the switch control circuit K2 are disconnected, the power end B and the load end C are disconnected, and the electronic equipment is thoroughly powered off.

In the above embodiment, the signal conversion is performed by setting the signal conversion circuit K1, and the electronic device is completely powered off by controlling the switch control circuit K2 to be turned off, so that the over-discharge of the battery is effectively avoided.

In some embodiments, the signal conversion circuit K1 includes a first variable circuit.

The first end of the first variable circuit is used as an input end of the signal conversion circuit K1 and is used for being connected with a controller of the electronic equipment to receive an enabling signal; the second end of the first variable circuit is used as an output end of the signal conversion circuit K1 and connected with an enabling end of the switch control circuit K2, and is used for sending a switch trigger signal to the enabling end of the switch control circuit K2.

Specifically, when the enable signal is a signal for controlling the switch circuit K to be turned on, the signal conversion circuit K1 converts the enable signal into a first level signal for triggering the switch control circuit K2 to be turned on; when the enable signal is a signal for controlling the switch circuit K to be turned off, the signal conversion circuit K1 converts the enable signal into a second electrical signal for triggering the switch control circuit K2 to be turned off.

The first level signal and the second level signal are different signals. For example, the first level signal is a high level signal, and the second level signal is a low level signal; alternatively, the second level signal is a high level signal, and the first level signal is a low level signal.

In the above embodiment, the purpose of effectively controlling the switch control circuit K2 can be achieved by providing the signal conversion circuit K1 to perform signal conversion.

In some embodiments, the function of the first variable circuit may be implemented using a single-chip microcomputer, for example, using an STM32 single-chip microcomputer. When the singlechip acquires an enabling signal for controlling the on of the switching circuit K, outputting a first level signal; when the singlechip acquires an enabling signal for controlling the switching circuit K to be closed, a second level signal is output. It should be noted that, setting the single-chip microcomputer to output the high-level signal or the low-level signal according to different input signals is conventional prior art, and the person skilled in the art can obtain the signal without performing creative labor, which is not described here.

In some embodiments, the function of the first variable circuit may be implemented by one or more controllable switches. Specifically, the second end of the first variable circuit is connected with the battery of the electronic device, and the third end of the first variable circuit is connected with the ground wire port of the electronic device.

When the enable signal is acquired, the one or more controllable switches may control the second terminal of the first variable circuit to be connected or disconnected with the third terminal of the first variable circuit. Because the third end of the first variable circuit is connected with the ground wire port of the electronic equipment, when the second end of the first variable circuit is conducted with the third end of the first variable circuit, the second end of the first variable circuit outputs a low-level signal; since the second terminal of the first variable circuit is connected to the battery of the electronic device, the second terminal of the first variable circuit outputs a high level signal when the second terminal of the first variable circuit is disconnected from the third terminal of the first variable circuit.

The high level signal may be set as a first level signal, and the low level signal may be set as a second level signal; alternatively, the high level signal may be set as the second level signal, and the low level signal may be set as the first level signal, which is not limited in this embodiment.

In the above embodiment, the level signal output by the first variable circuit is adjusted by the level signal of the ground wire port of the electronic device and the battery level signal of the electronic device, and other power supplies are not required to be connected, so that the electronic device is simple in structure and convenient to use.

In some embodiments, the second end of the first variable circuit is connected to a battery of the electronic device through a set load. The set load is a load with a larger resistance value so as to avoid the battery grounding short circuit when the second end and the third end of the first variable circuit are conducted. The set load may employ a resistor R having a resistance value of 100K as shown in fig. 3.

In some embodiments, as shown in fig. 3, the switch control circuit K2 includes a second variable circuit. The first end of the second variable circuit is used as an enabling end of the switch control circuit and is connected with the output end of the signal conversion circuit, the second end of the second variable circuit is used as a power end of the switch control circuit and is used for being connected with a battery of the electronic equipment, and the third end of the second variable circuit is used as a load end of the switch control circuit and is used for being connected with an electricity load of the electronic equipment.

When the first end of the second variable circuit receives the first level signal, the circuit between the second end and the third end of the second variable circuit is conducted, the power end B is connected with the load end C, and the battery of the electronic equipment can supply power to the electric load; when the first end of the second variable circuit receives the second level signal, the circuit between the second end and the third end of the second variable circuit is closed, the power end B and the load end C are disconnected, and the electronic equipment is completely powered off.

In some embodiments, the function of the first variable circuit and/or the second variable circuit may be implemented by a controllable switch. For example, the controllable switch in this embodiment may be a power switch such as a triode, an electromagnetic relay, or an Insulated Gate Bipolar Transistor (IGBT), a Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET), etc., which is not limited in this embodiment.

In a specific embodiment, as shown in fig. 3, if the signal for controlling the on state of the switching circuit K in the enable signal is a high level signal and the signal for controlling the off state of the switching circuit K is a low level signal, the first variable circuit may be an N-type MOSFET, the second variable circuit may be a P-type MOSFET, Q1 is the N-type MOSFET, and Q2 is the P-type MOSFET in fig. 3. The grid electrode of the Q1 is used as a first end of the first variable circuit, the drain electrode of the Q1 is used as a second end of the first variable circuit, and the source electrode of the Q1 is used as a third end of the first variable circuit. The gate of Q2 is used as the first end of the second variable circuit, the drain of Q2 is used as the third end of the second variable circuit, and the source of Q2 is used as the second end of the second variable circuit.

Specifically, when the electronic device is operating normally, the controller of the electronic device outputs a high level signal to the gate of Q1, at this time, Q1 is turned on, the drain level of Q1 is pulled down by the source of Q1, at this time, the drain of Q1 is at a low level, and the first level signal is at a low level. The drain electrode of the Q1 is connected with the grid electrode of the Q2, the grid electrode of the Q2 is also in a low level, the Q2 is conducted at the moment, and the battery of the electronic equipment can supply power to the electric load. When the electronic equipment is required to be completely powered off, the controller of the electronic equipment outputs a low-level signal to the grid electrode of the Q1, at the moment, the Q1 is cut off, the drain electrode level of the Q1 is pulled up by the battery of the electronic equipment, at the moment, the drain electrode of the Q1 is high level, and the second level signal is high level. The drain electrode of Q1 is connected with the grid electrode of Q2, and the grid electrode of Q2 is also high level, and Q2 is cut off at the moment, and the battery of the electronic equipment is thoroughly powered off.

In some embodiments, if the signal for controlling the on state of the switch circuit K in the enable signal is a low level signal and the signal for controlling the off state of the switch circuit K is a high level signal, the first variable circuit may be a P-type MOSFET, and the second variable circuit may be an N-type MOSFET.

A transistor, an IGBT, or a relay may be used instead of the MOSFET, and the embodiment is not limited.

In some embodiments, as shown in fig. 4, the load terminal C of the power control device may also be connected to a charging component of the electronic device. The charging component of the electronic device is typically a charging interface of the electronic device, such as a Type-C interface, a lighting interface, and the like.

Based on this, when the enable signal obtained by the enable terminal a is a signal for controlling the switch circuit K to be turned off, and the power terminal B and the load terminal C are turned off, the battery of the electronic device cannot supply power to any power-consuming load, and cannot be charged. When the enabling signal acquired by the enabling terminal A is a signal for controlling the switching circuit K to be conducted, the power terminal B is connected with the load terminal C, the battery of the electronic equipment can supply power to the power-using load, and the external power supply can charge the battery through the charging component.

In some embodiments, the charging component and the electrical load of the electronic device are both connected to the battery of the electronic device through a voltage converter, typically a DC/DC converter. Based on this, as shown in fig. 4, in the embodiment of the present utility model, the load terminal C of the power control device is provided to be connected to the voltage converter, that is, the load terminal C of the power control device is connected to the power load and the charging member through the voltage converter.

In the above embodiment, the charging unit of the electronic device is connected to the load terminal C, so that when the charging unit is connected to the external power supply, the controller sends an enable signal to the switch circuit K, so that the power terminal B is connected to the load terminal C, the battery of the electronic device can supply power to the power-consuming load, and the external power supply can also charge the battery through the charging unit.
