First embodiment
In view of this, the utility model provides a power consumption test circuit 100 can test the power consumption of electronic equipment under each scene under the condition of not tearing open the machine.
Referring to fig. 1, a block diagram of a circuit structure of a power consumption testing circuit 100 according to the present invention is shown. The power consumption testing circuit 100 includes a charging interface 110, a switch switching module 120, a power module 130, and a system load module 140, wherein the charging interface 110 is electrically connected to the power module 130 through the switch switching module 120, the charging interface 110 is further electrically connected to the system load module 140 through the switch switching module 120, and the power module 130 is electrically connected to the system load module 140.
The charging interface 110 is configured to receive a power signal input by an external power source. The charging interface 110 may be, but is not limited to, a Universal Serial Bus (USB) interface, a Type-C interface, a Lightning interface, or the like.
The switch switching module 120 is electrically connected to the charging interface 110, and is configured to switch states under the control of the system load module 140. Specifically, the switch switching module 120 is configured to switch to the first state in response to the second control signal generated and transmitted by the system load module 140.
It should be noted that the switch switching module 120 includes a first state and a second state. By default, the switch switching module 120 is in the second state, and when the switch switching module 120 receives the second control signal, the switch switching module switches from the second state to the first state.
When the switch switching module 120 is in the second state, the charging interface 110 may be electrically connected to the power module 130 through the switch switching module 120, and meanwhile, the charging interface 110 cannot be electrically connected to the system load module 140 through the switch switching module 120; on the contrary, when the switch switching module 120 is in the first state, the charging interface 110 cannot be electrically connected to the power module 130 through the switch switching module 120, and meanwhile, the charging interface 110 can be electrically connected to the system load module 140 through the switch switching module 120.
Referring to fig. 2, a circuit structure diagram of the switch switching module 120 in one embodiment is shown. The switch switching module 120 includes a first switch tube 121 and a second switch tube 122, the system load module 140 is electrically connected to both the control port CTL1 of the first switch tube 121 and the control port CTL2 of the second switch tube 122, the charging interface 110 is electrically connected to both the signal input terminal IN1 of the first switch tube 121 and the signal input terminal IN2 of the second switch tube 122, the signal output terminal OUT1 of the first switch tube 121 is electrically connected to the power module 130, and the signal output terminal OUT2 of the second switch tube 122 is electrically connected to the system load module 140.
It is understood that the first switch tube 121 and the second switch tube 122 are both used for switching the switch state under the control of the system load module 140. Specifically, the first switch tube 121 is configured to be turned off in response to the second control signal, and the second switch tube 122 is configured to be turned on in response to the second control signal.
When the first switch tube 121 is in the off state and the second switch tube 122 is in the on state, the switch switching module 120 is in the first state; conversely, when the first switch tube 121 is in the on state and the second switch tube 122 is in the off state, the switch switching module 120 is in the second state.
It should be noted that the second control signal may be a high level signal or a low level signal. In addition, since the first switch tube 121 and the second switch tube 122 operate differently after receiving the same command, the polarities of the first switch tube 121 and the second switch tube 122 are opposite.
For example, if the second control signal is a high level signal, the first switch tube 121 may be a PMOS tube or a PNP transistor, and the second switch tube 122 may be an NMOS tube or an NPN transistor. In an alternative embodiment, the first switch tube 121 is MP62040-1, and the second switch tube 122 is TPS 22963.
For another example, if the second control signal is a low level signal, the first switch tube 121 may be an NMOS tube or an NPN transistor, and the second switch tube 122 may be a PMOS tube or a PNP transistor.
Referring to fig. 3, a circuit structure diagram of the switch switching module 120 in another embodiment is shown. The switch switching module 120 includes a solenoid valve 123, a first contact 124 and a second contact 125, the system load module 140 is electrically connected to the power module 130 through the solenoid valve 123 and the first contact 124, and the system load module 140 is also electrically connected to the system load module 140 through the solenoid valve 123 and the second contact 125.
The solenoid valve 123 is configured to receive a second control signal generated and transmitted by the system load module 140, and control the first contact 124 to open and the second contact 125 to close in response to the second control signal.
It will be appreciated that the first contact 124 is a normally closed contact and the second contact 125 is a normally open contact. The solenoid valve 123 is energized when it receives the second control signal, thereby causing the first contact 124 to open and the second contact 125 to close.
It should be noted that, when the solenoid valve 123 is powered (i.e., the first contact 124 is opened and the second contact 125 is closed), the switch switching module 120 is in the first state; conversely, when the solenoid valve 123 is de-energized (i.e., the first contact 124 is closed and the second contact 125 is open), the switch switching module 120 is in the second state.
In an alternative embodiment, in order to avoid the charging interface 110 from being damaged by the reverse current flowing to the charging interface 110 when the system load module 140 or the power module 130 is short-circuited, the switch switching module 120 further includes a first diode and a second diode, the solenoid valve 123, the anode of the first diode, the cathode of the first diode and the first contact 124 are electrically connected in sequence, and the solenoid valve 123, the anode of the second diode, the cathode of the second diode and the second contact 125 are electrically connected in sequence.
The power module 130 is used for storing electric energy, and is used for supplying power to the system load module 140 when the system load module 140 is in the normal operation mode to maintain the normal operation of the electronic device. Meanwhile, the power module 130 is further configured to receive a first control signal generated and transmitted by the system load module 140, and stop supplying power to the system load module 140 in response to the first control signal.
Referring to fig. 2 or fig. 3, the power module 130 includes a battery 134 and a charging unit 132. The switch switching module 120, the charging unit 132 and the battery 134 are electrically connected in sequence, and the charging unit 132 is electrically connected to the system load module 140.
Specifically, the charging unit 132 includes a third switching tube 136 and a charging chip 138, the charging chip 138 is electrically connected to the system load module 140, the control terminal CTL3 of the third switching tube 136 is electrically connected to the charging chip 138, the signal input terminal IN3 of the third switching tube 136 is electrically connected to the battery 134, and the signal output terminal OUT3 of the third switching tube 136 is electrically connected to the system load module 140. The charging chip 138 is configured to receive a first control signal generated and transmitted by the system load module 140, and control the third switching tube 136 to open in response to the first control signal, so that the battery 134 stops supplying power to the system load module 140.
It should be noted that, in a default condition, the third switching tube 136 is in a conducting state, and at this time, the battery 134 may supply power to the system load module 140 through the charging unit 132; when the third switching tube 136 is turned off in response to the first control signal, the battery 134 is disconnected from the system load module 140.
In addition, when the switch switching module 120 is in the second state, the charging interface 110 transmits a power signal input by an external power source to the charging unit 132 through the switch switching module 120, and the charging unit 132 is configured to charge the battery 134. When the switch switching module 120 is in the first state, the charging interface 110 cannot be connected to the power module 130 through the switch switching module 120, and the charging unit 132 cannot charge the battery 134.
In an alternative embodiment, the third switching tube 136 may be a switching tube such as a triode, a MOS tube, or the like, and may also be replaced by another switching device (e.g., a solenoid valve), which is not limited herein.
The system load module 140 is used to enter a power consumption test mode in response to a user's operation. When entering the power consumption test mode, the system load module 140 is configured to generate a first control signal and a second control signal, and transmit the first control signal to the power module 130 and transmit the second control signal to the switch switching module 120.
The first control signal is used to instruct the power supply module 130 to stop supplying power to the system load module 140; the second control signal is used to instruct the switch switching module 120 to switch to the first state.
Specifically, if the switch switching module 120 includes a first switch tube 121 and a second switch tube 122, the system load module 140 is configured to transmit a second control signal to the first switch tube 121 and the second switch tube 122; the first switch tube 121 is configured to be turned off in response to a second control signal, and the second switch tube 122 is configured to be turned on in response to the second control signal.
If the on-off switching module 120 includes the solenoid valve 123, the system load module 140 is configured to transmit the second control signal to the solenoid valve 123. The solenoid valve 123 is used for controlling the first contact 124 to be opened and the second contact 125 to be closed in response to the second control signal.
In addition, the system load module 140 is configured to transmit a first control signal to the third switch tube 136, and the third switch tube 136 is configured to open in response to the first control signal so that the battery 134 stops supplying power to the system load module 140.
It should be noted that the system load module 140 may be a main control circuit board and other devices of an electronic device (e.g., a mobile phone), and the system load module 140 may work normally and implement related functions of the electronic device, such as making a call, watching video, listening to music, etc., in the presence of a power supply.
It should be noted that, in a normal operating mode, the system load module 140 is usually in a normal operating mode, and when a user performs a relevant operation (for example, clicks a relevant icon or key), the system load module 140 enters a power consumption test mode in response to the operation; and when the user no longer needs to perform the power consumption test, the user can select to exit the power consumption test mode.
The principle of the utility model is that: when the system load module 140 does not enter the power consumption test mode, the switch switching module 120 is in the second state by default, the third switch tube 136 is in the conducting state, and at this time, if the charging interface 110 is not connected with an external power supply, the battery 134 supplies power to the system load module 140 by using the charging unit 132; if the charging interface 110 is externally connected to an external power source, the external interface charges the battery 134 through the charging interface 110 and the charging unit 132, and supplies power to the system load module 140 through the charging unit 132.
When the system load module 140 enters the power consumption test mode, the charging interface 110 needs to be externally connected with an external power supply, the system load module 140 generates a first control signal and a second control signal, the first control signal is used for controlling the third switch tube 136 to be disconnected, so that the power supply of the system load module 140 by the battery 134 is avoided, the second control signal is used for controlling the switch switching module 120 to be switched to the first state, so that the power supply signal is transmitted to the system load module 140 through the switch switching module 120 to supply power to the system load module 140, at the moment, a tester can directly measure the working current of the system load module 140 through the charging interface 110 under the condition of not disassembling the machine, so that the power consumption of the electronic equipment is determined, and the test efficiency is greatly improved.

In other embodiments, the tester may also obtain the operating current of the system load module 140 through a device such as a multimeter. In addition, the programmable power supply and the electronic device can be connected by a charging wire.
