It is to be understood that the portable lamp is widely used in outdoor places such as various night searching, rescue, inspection, tracking, rush repair, railway construction, offshore and other workplaces to provide a user with a mobile lighting function. Currently, portable lamps on the market are generally only powered by a single lithium battery, and can only maintain normal operation of the portable lamp in a timely charging mode until the lithium battery is consumed. However, when a user uses the portable lamp in an outdoor place, the portable lamp is inconvenient to charge in time, so that the portable lamp cannot be carried by hand due to no electricity, and inconvenience is brought to the user.
Accordingly, the present utility model proposes a portable lamp with dual battery power, referring to fig. 1, comprising:
a lithium battery 41;
a dry cell 42;
a portable lamp body;
a battery switching circuit 30, wherein a first input end of the battery switching circuit 30 is connected with an output end of the lithium battery 41, a second input end of the battery switching circuit 30 is connected with an output end of the dry battery 42, and an output end of the battery switching circuit 30 is connected with an input end of the portable lamp; the battery switching circuit 30 is used for controlling the connection on/off between the lithium battery 41 and the portable lamp body and the connection on/off between the dry battery 42 and the portable lamp body;
the voltage detection circuit 20 is electrically connected with the output end of the lithium battery 41, and is used for detecting the voltage of the lithium battery 41 and outputting a voltage signal;
the main control circuit 10 is electrically connected to the controlled end of the battery switching circuit 30 and the output end of the voltage detection circuit 20, and is used for controlling the battery switching circuit 30 to disconnect the path between the lithium battery 41 and the portable lamp and to conduct the path between the dry battery 42 and the portable lamp when detecting that the voltage of the lithium battery 41 is lower than a preset voltage according to the voltage signal.
It can be understood that most of the existing portable lamps are powered by a single lithium battery 41, and when the electric quantity of the lithium battery 41 is about to be exhausted, the portable lamps need to be charged in time to maintain the normal operation of the portable lamps. However, the portable lamp is widely used in outdoor places, and when a user cannot find a power supply in time to charge the portable lamp, the portable lamp cannot work normally due to no power. In order to overcome the above disadvantages, the portable lamp is provided with two batteries, namely the lithium battery 41 and the dry battery 42, and when the electric quantity of the lithium battery 41 is about to be exhausted, the portable lamp is switched from the power supply mode of the lithium battery 41 to the power supply mode of the dry battery 42 by controlling the battery switching circuit 30 so as to improve the cruising ability of the portable lamp. Further, before switching of the power supply mode is performed, it is necessary to determine whether or not the current lithium battery 41 reaches a condition where normal power supply is not possible. The utility model detects the voltage of the lithium battery 41 in real time through the voltage detection circuit 20, and outputs the detected voltage to the main control circuit 10 as a voltage signal, so that the main control circuit 10 detects the voltage value of the lithium battery 41 according to the voltage signal. It should be understood that the standard voltage output by the lithium battery 41 is 3.7V, and a voltage output by the lithium battery 41 as low as 3.3V may be regarded as about to be exhausted, whereas a voltage output by the lithium battery 41 cannot be lower than 3.3V, otherwise the battery may be damaged. When the main control circuit 10 detects that the lithium battery 41 is smaller than 3.3V according to the voltage signal, the electric quantity of the lithium battery 41 is considered to be about to be exhausted, and the battery switching circuit 30 is controlled to start working so as to switch the portable lamp from the power supply mode of the lithium battery 41 to the power supply mode of the dry battery 42, so that the dry battery 42 can replace the lithium battery 41 to continuously provide working voltage for the portable lamp, and the service life of the portable lamp is prolonged.
In practical applications, the voltage detection circuit 20 may be implemented using a resistive divider circuit. The resistor voltage dividing circuit includes a first resistor and a second resistor, divides the voltage of the lithium battery 41 according to the resistance ratio of the first resistor and the second resistor, and sends the divided voltage to the main control circuit 10 in the form of a voltage detection signal, and the main control circuit 10 obtains the divided voltage value according to the voltage detection signal, and detects the current voltage value of the lithium battery 41 according to the preset resistance ratio. When the main control circuit 10 detects that the voltage value of the current lithium battery 41 is lower than 3.3V, it determines that the electric quantity of the current lithium battery 41 is about to be exhausted, namely, controls the battery switching circuit 30 to switch the portable lamp from the lithium battery 41 power supply mode to the dry battery 42 power supply mode, namely, to disconnect the passage between the lithium battery 41 and the portable lamp, so that the lithium battery 41 stops providing the working voltage for the portable lamp, and simultaneously, the passage between the dry battery 42 and the portable lamp is conducted, so that the dry battery 42 replaces the lithium battery 41 to provide the working voltage for the portable lamp. In addition, when the electric power of both the lithium battery 41 and the dry battery 42 is about to be exhausted, the user can manually replace the new dry battery 42 to make the new dry battery 42 continue to supply the operating voltage to the portable lamp, thereby increasing the service life of the portable lamp.
The utility model provides a portable lamp with double-battery power supply, which comprises a lithium battery 41, a dry battery 42, a portable lamp body, a battery switching circuit 30, a voltage detection circuit 20 and a main control circuit 10; the voltage detection circuit 20 is configured to detect the voltage of the lithium battery 41 in real time, so as to output a corresponding voltage signal to the main control circuit 10, when the main control circuit 10 detects that the lithium battery 41 is lower than a preset voltage according to the voltage signal, determine that the current electric quantity of the lithium battery 41 is about to be exhausted, and control the battery switching circuit 30 to switch from the lithium battery 41 power supply mode to the dry battery 42 power supply mode, that is, disconnect the path between the lithium battery 41 and the portable lamp, and conduct the path between the dry battery 42 and the portable lamp, so that the dry battery 42 can replace the lithium battery 41 to continuously provide the working voltage for the portable lamp, thereby solving the limitation of supplying power to the portable lamp by using the single lithium battery 41, and increasing the service life of the portable lamp.

It can be understood that the first switching circuit 52 in this embodiment is implemented by using the third MOS transistor Q3, and the second switching circuit 51 is implemented by using the fourth MOS transistor Q4. In practical application, the voltage detection circuit 20 detects the voltage of the lithium battery 41 in real time and outputs a corresponding voltage signal to the main control circuit 10, when the main control circuit 10 detects that the lithium battery 41 is lower than a preset voltage according to the voltage signal, the battery switching signal is output to the third MOS transistor Q3 and the fourth MOS transistor Q4, the third MOS transistor Q3 receives the battery switching signal and turns on the passage between the dry battery 42 and the portable lamp, the fourth MOS transistor Q4 receives the battery switching signal and turns off the passage between the lithium battery 41 and the portable lamp, so that the lithium battery 41 stops providing the working voltage for the portable lamp, and the dry battery 42 replaces the lithium battery 41 to provide the working voltage for the portable lamp.

In addition, the charge-discharge management chip is further used for detecting whether the connected external voltage has a battery overcharge phenomenon or not and detecting whether the voltage output by the lithium battery 41 has a battery overdischarge phenomenon or not, so that when the battery has the overcharge and overdischarge phenomena, the lithium battery 41 is timely controlled to stop charging/discharging, the use safety of the lithium battery 41 is ensured, and the service life of the lithium battery 41 is prolonged.
