In the embodiment of the present application, the user controls whether the back clip battery 102 charges the mobile terminal 101 by controlling the switch provided on the back clip battery 102.
Illustratively, when the user presses the 3 second switch for the first time (at which time the switch is closed) and when the battery cell 204 of the back-clamp battery 102 is in a normal voltage (non-low-power) state, the specific process of charging the mobile terminal 101 by the back-clamp battery 102 is: when the switch is closed, the singlechip 302 receives the connection of the voltage conversion module 402 and the first connector 202, which is connected with the voltage conversion module 402, the voltage conversion module 402 obtains the voltage of the battery cell 204, and the voltage value is raised to the voltage value required for charging the mobile terminal 101, and then the mobile terminal 101 is charged through the first connector 202, so that when the back clamp battery 102 is in a normal voltage state, the back clamp battery 102 charges the mobile terminal 101 through the first connector 202.
Illustratively, there are two paths for powering the service device 103:
The first strip provides power to the mobile terminal 101 via the back splint battery 102 to the service device 103: the mobile terminal 101 transmits the electric quantity of the mobile terminal 101 to the power supply switching circuit 303 through the first connector 202, and establishes connection between the first connector 202 and the second connector 203 in the power supply switching circuit 303 according to the control signal of the single chip microcomputer 302, so that the mobile terminal 101 supplies power to the service equipment 103.
The second strip powers the back splint battery 102 to service device 103: the voltage conversion module 402 in the back splint battery 102 obtains the voltage of the battery cell 204, and raises the obtained voltage of the battery cell to the voltage required for supplying power to the service device 103, then transmits the raised voltage to the power switching circuit 303, and establishes connection between the voltage conversion module 402 and the second connector 203 in the power switching circuit 303 according to the control signal of the singlechip 302, thereby realizing that the back splint battery 102 supplies power to the service device 103.
When the battery cell 204 of the back splint battery 102 is in a normal voltage (non-low voltage) state, the voltage conversion module 402 obtains the voltage of the battery cell 204 and raises the voltage to a voltage required for supplying power to the service device 103, and then sends the raised voltage to the power switching circuit 303, at this time, according to a control signal of the singlechip 302, the power switching circuit 303 establishes connection between the voltage conversion module 402 and the second connector 203, so as to realize that the back splint battery 102 supplies power to the service device 103.
The power detection module 401 monitors the power value of the battery cell 204 in real time, and sends the power value of the battery cell 204 collected in real time to the integrated circuit module 403, so that the integrated circuit module 403 monitors whether the back splint battery 102 is in a low power state.
When the electric quantity detecting module 401 monitors that the electric quantity value of the battery cell 204 is in a non-low electric state in real time, the voltage converting module 402 obtains the voltage of the battery cell 204 in real time, converts the obtained voltage into a voltage value required for charging the mobile terminal 101 and a voltage required for supplying power to the service device 103, charges the mobile terminal 101 through the first connector 202, and meanwhile, the voltage converting module 402 transmits the voltage value required for supplying power to the service device 103 to the power supply switching circuit 303, and then supplies power to the service device 103 through the second connector 203.
For example: the voltage value of the battery cell 204 obtained by the voltage conversion module 402 at this time is 3V, (since the voltage value for charging the mobile terminal and supplying power to the service device is generally 5V), the voltage of the obtained battery cell 204 is raised to 5V by the voltage conversion module 402, and then the mobile terminal is charged through the first connector 202; meanwhile, the voltage conversion module 402 sends the raised voltage of 5V to the power switching circuit 303, and the power switching circuit 303 is electrically connected to the second connector 203, so that the service device is powered through the second connector 203.
The integrated circuit module 403 compares the voltage value in the received electrical value of the battery cell 204 with a preset threshold, and when the current electrical value of the battery cell 204 is less than the preset threshold, the integrated circuit module 403 generates an interrupt signal and sends the interrupt signal to the single-chip microcomputer 302.
The singlechip 302 controls the power supply switching circuit 303 according to the received interrupt signal, and at this time, according to the difference of external devices of the back splint battery 102, the singlechip controls the power supply switching circuit 303 in the following two cases:
First case: when the back clamp battery 102 is only connected with the mobile terminal 101, and the switch of the back clamp battery 101 is in a closed state, the singlechip 302 controls the switch to be turned off according to the received interrupt signal, so that the connection between the voltage conversion module 402 and the first connector 202 is cut off, the battery cell 204 is disconnected to charge the mobile terminal 101 through the first connector 202, and the back clamp battery 102 is disconnected to charge the mobile terminal 101.
Second case: when the back clamp battery 102 is externally connected with the mobile terminal 101 and the service equipment 103, at this time, the back clamp battery 102 is in a closed state, the single chip microcomputer 302 controls the switch to be turned off according to the received interrupt signal, so that the connection between the voltage conversion module 402 and the first connector 202 is cut off, the battery cell 204 charges the mobile terminal 101 through the first connector 202, meanwhile, the single chip microcomputer 302 controls the power supply switching circuit 303 to establish the connection between the first connector 202 and the second connector 203 according to the received interrupt signal, the connection between the mobile terminal 101 and the service equipment 103 is further realized, then the connection between the voltage conversion module 402 and the second connector 203 is cut off, the power supply of the battery cell 204 to the service equipment 103 through the second connector 203 is cut off, and the power supply of the back clamp battery 102 to the mobile terminal 101 is ensured when the electric quantity of the back clamp battery 102 is too low, and meanwhile, the service equipment 103 is supplied with power through the mobile terminal 101, and normal use of the service equipment 103 is ensured.
For example: assuming that the preset threshold is 1.5V, the back-clamping battery 102 simultaneously connects the mobile terminal 101 and the service device 103, and at this time, the back-clamping battery 102 switch is in a closed state (i.e., the back-clamping battery 102 charges the mobile terminal 101). The electric quantity detection module 401 monitors the electric quantity value of the battery cell 204 in real time, and sends the electric quantity value of the battery cell 204 acquired in real time to the integrated circuit module 403, the integrated circuit module 403 compares the voltage value in the received electric quantity value of the battery cell 204 with a preset threshold value of 1.5V, and when the voltage value of the current battery cell 204 is smaller than 1.5V, the integrated circuit module 403 generates an interrupt signal and sends the interrupt signal to the singlechip 302; the singlechip 302 controls the switch to be disconnected according to the received interrupt signal, cuts off the connection between the voltage conversion module 402 and the first connector 202 so as to disconnect the battery cell 204 and charge the mobile terminal 101 through the first connector 202, meanwhile, the singlechip 302 automatically controls the power supply switching circuit 303 to firstly establish the connection between the first connector 202 and the second connector 203 according to the received interrupt signal so as to establish the connection between the mobile terminal 101 and the service equipment 103, and then cuts off the connection between the voltage conversion module 402 and the second connector 203 so as to disconnect the connection between the battery cell 204 and the service equipment 103 so as to supply power to the service equipment 103 through the second connector 203, thereby ensuring that when the electric quantity of the back clamp battery 102 is too low, the battery cell 102 is cut off to charge the mobile terminal 101, and meanwhile, the mobile terminal 101 supplies power to the service equipment 103 so as to ensure the normal use of the service equipment 103.
Further, the back splint battery 102 provided in the embodiment of the present application further includes: an indicator light; the indicator light is electrically connected with the single chip microcomputer 302.

And the indicator lamp is used for starting the indicating operation matched with the second control signal after receiving the second control signal.
The indicator light is provided on the housing of the back splint battery 102.
When the back splint battery 102 is in the low-power state, the singlechip 302 receives the interrupt signal generated by the integrated circuit module 403 and controls the indicator lamp to flash, so as to prompt the user that the current back splint battery 102 is in the low-power state and prompt the user to charge the back splint battery 102 in time.
Further, the second connector is further configured to connect to an adapter, so as to charge the battery cell 204 through the adapter.
The adapter refers to an interface converter, and the second connector 203 (i.e., a USB interface) may be connected to the adapter, and connected to a power source through the adapter, so as to charge the battery cell 204 of the back-clamping battery 102.
When the user inserts the adapter into the second connector (i.e., the USB interface), the integrated circuit module 403 detects the insertion of the adapter, and collects the voltage of the adapter, and sends the collected voltage of the adapter to the voltage conversion module 402, where the voltage conversion module 402 processes the received voltage and converts the voltage into a voltage value required for charging the battery cell 204 of the back-clamp battery 102, thereby charging the battery cell 204 of the back-clamp battery 102.
Further, the back splint battery 102 provided in the embodiment of the present application further includes: a housing;
