Description
Technical Field
[0001] The utility model relates to the technical field of charging, in particular to an emergency power bank capable of replacing charging cores with dry batteries. Background Art
[0002] In recent years, with global warming, various extreme climates have occurred frequently. Once there is excessive rainfall in a certain area, long power outages are often prone to occur. Due to long power outages, communication electronic equipment is difficult to find a suitable place to charge and continue battery life.
[0003] This product uses dry batteries commonly found in daily life as its energy source, is controlled by the buck-boost circuit and fast-charging protocol chip of the battery control board, and outputs fast charging via the USB port to provide emergency charging to mobile phones and other electronic devices, or to be used as emergency lighting at night. For this reason, technicians in this field have proposed an emergency power bank that can replace charging cells with dry batteries. Utility Model Content
[0004] In order to overcome the above-mentioned technical problems, the purpose of the utility model is to provide an emergency power bank in which dry batteries can be replaced with rechargeable cells, comprising a mobile power supply housing, in which dry batteries are electrically connected, a battery control motherboard is arranged in the mobile power supply housing, a fast charging protocol chip is arranged in the mobile power supply housing, and the fast charging protocol chip is used to control the output of current. An emergency flashlight and a USB interface are installed at the front end of the mobile power supply housing.
[0005] Preferably, a key switch is also provided at the front end of the mobile power supply housing, and the key switch is used to control the switch of the emergency flashlight.
[0006] Preferably, a dry cell cabin is provided on the housing of the mobile power source, and the dry cell is installed in the dry cell cabin to supply power to the mobile power source.
[0007] Preferably, the dry battery cabin is detachably connected to a rear shell.
[0008] Preferably, a power indicator light for detecting the power level of the dry cell battery is provided on the housing of the mobile power source.
[0009] Beneficial effects of the utility model:
[0010] The internal components of the utility model adopt the design technology of the buck-boost circuit and apply the fast charging chip technology. It uses common dry batteries as the energy source and does not rely on alternating current. The energy source can be replaced through the detachable back cover, and even if a certain area is out of power for a long time, it is easy to obtain common energy sources in daily life. The conversion of the buck-boost circuit is controlled by the power control motherboard, and the fast charging protocol chip can match the current to the fast charging protocol. The power button switch can be used to control the function of both. A single press enters the power bank mode to charge electronic devices. Long press the button to turn on the emergency lighting flashlight. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] The utility model is further described below in conjunction with the accompanying drawings.
[0012] Figure 1 It is a schematic diagram of the utility model.
[0013] In the figure: 1. Mobile power supply housing; 2. Dry battery; 3. Emergency flashlight; 4. USB interface; 5. Push button switch; 6. Dry battery compartment; 7. Back cover; 8. Power indicator light. DETAILED DESCRIPTION
[0014] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] See also Figure 1 As shown, an emergency power bank in which a rechargeable battery cell can be replaced by a dry battery comprises a mobile power housing 1, a dry battery 2 is electrically connected inside the mobile power housing 1, a battery control mainboard is arranged inside the mobile power housing 1, a fast charging protocol chip is arranged on the mobile power housing 1, and the fast charging protocol chip is used to control the output of current, an emergency flashlight 3 and a USB interface 4 are installed at the front end of the mobile power housing 1, a key switch 5 is also arranged at the front end of the mobile power housing 1, and the key switch 5 is used to control the switch of the emergency flashlight 3, a dry battery cabin 6 is arranged on the mobile power housing 1, and the dry battery 2 is installed in the dry battery cabin 6 to power the mobile power, and a rear shell 7 is detachably connected to the dry battery cabin 6, and a power indicator light 8 for detecting the power level of the dry battery 2 is arranged on the mobile power housing 1.
