[0174] like Figure 7 As shown, the main control module serves as the central module of the entire modular power bank and can be used as a power bank alone. The module is equipped with two 21700 lithium batteries with a rated capacity of up to 10000mAh. The batteries can be replaced by opening the removable battery compartment door on the module. The module is equipped with a USB Type-C interface for charging power input and two dual USB Type-A interfaces for charging electrical devices. The power switch with status indicator on the top of the main module is the switch for the entire charging system. Press and hold for 3 seconds to start / turn off. The indicator light on the button is always on when the module is connected to a charging power source. The three-level power indicator on the top of the main module displays the total power of the current system (including the connected battery compartment module). When the power switch with status indicator is short pressed, the three-level power indicator lights up and turns off after 10 seconds. Both sides of the main module can be connected to the battery compartment module or the flashlight module (such as Figure 14 ), when you need to connect, stretch out the upper side, fold it 180°, and then push it back until it engages with the magnetic connection unit at the bottom. At this time, the side becomes a bevel (as shown in the steps below). Figure 7 The bottom of the main module can be connected to the wireless charging module, the solar charging module or the positioning navigation module (such as Figure 16 , 17 , 18), when connection is required, the sliding interface protective cover at the bottom must be opened first. The main module can be connected to the battery compartment module, the wireless charging module, the solar charging module, or the positioning navigation module at the same time.
[0175] like Figure 8 As shown, the battery compartment module is equipped with a 21700 lithium battery with a rated capacity of 5000mAh. The battery can be replaced by opening the removable battery compartment door on the module. Its main functions are as follows: ① Connecting with the main control module to expand the total capacity. Up to two battery compartment modules can be connected to the main control module; ② Connecting with the flashlight module to power it (such as Figure 15 The three positions of the working mode switch on the top of the module are "connect - off - power display". When it is in the "connect" position, it can be used in combination with the main control module. When it is in the "off" position, it is in the off state and does not do anything. When it is in the "power display" position, the three-level power indicator will show the current power of the battery compartment module. There is a hook at the bottom of the module. When it is connected to the main control module, pull it out and rotate it 90° before use.
[0176] As Figure 9 shown, the flashlight module needs to be connected and combined with the main control module or the battery compartment module before it can be used. The two-stage brightness adjustment switch on the module has two positions: "on - off". When connected and combined with the main control module or the battery compartment module, turn the switch to "on", and the LED light will turn on for lighting use; turn the switch to "off", and the LED light will turn off.
[0177] As Figure 10 shown, the wireless charging module needs to be connected and combined with the main control module before it can be used, and it can charge devices that support wireless charging reception. During charging, place the device on the surface of the module.
[0178] As Figure 11 shown, the solar charging module needs to be connected and combined with the main control module before it can be used, and it can be used as a power source to supply power to the main control module. The two-stage brightness adjustment switch on the module has two positions: "on - off". When connected and combined with the main control module or the battery compartment module, turn the switch to "on", and power supply will start; turn the switch to "off", and it will stop working. When in use, pull out the photovoltaic panels on both sides of the module and unfold them along the hinge connection, and then turn the switch to "on".
[0179] As Figure 12 shown, the positioning and navigation module needs to be connected and combined with the main control module before it can be used, and it can display the current time, longitude, and latitude. The two-stage brightness adjustment switch on the module has two positions: "on - off". When connected and combined with the main control module or the battery compartment module, turn the switch to "on", and the LCD information display screen will turn on and the GPS system will start operating; turn the switch to "off", and it will stop working.
[0180] Only some exemplary embodiments of the present invention are described above by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention.
