technical field

The invention relates to the field of solar power supplies, in particular to a multifunctional portable solar power supply.

Background technique

At present, the shortage of energy and the shortage of electricity have become well-known social problems. Solar energy is a clean natural energy, and it is ubiquitous, easy to use, and not restricted by geographical conditions. Due to these advantages, solar photovoltaic power generation technology has been widely concerned and applied.

With the development of communication technology and the promotion of various mobile phone application software, mobile phones have become an indispensable part of people's lives. However, the long-term use of mobile phones makes the power consumption is also increasing rapidly. Insufficient power has become a major problem that plagues mobile phone users, and various power bank applications are born. However, the current charging treasure capacity is limited, and when people go out, especially when traveling outdoors, the battery capacity of the charging treasure is obviously not enough.

Existing portable lighting devices, such as flashlights, portable LED lamps, etc., all need other external power sources to power them, which makes it impossible to meet people's lighting needs for a long time without external power sources.

Contents of the invention

The object of the present invention is to propose a multifunctional solar portable power supply, aiming at solving the portability of outdoor backup power supply and providing a portable lighting device.

The purpose of the present invention is achieved through the following technical solutions:

A multifunctional solar portable power supply, comprising a casing, the bottom of the casing is movably connected with an adjustable foldable structure bracket, the center of the bracket is provided with a round hole; the front of the casing is provided with light touch buttons and two Symmetrically distributed high-power LED lights; one side of the housing is provided with a 5V Mini USB input port, and the other side is provided with a 5V USB output port; the back of the housing is equipped with a solar panel; the back of the housing is also equipped with There is a solar charging LED indicator light; the top of the shell is provided with a battery power LED indicator light; the inside of the shell is also equipped with an energy storage lithium battery and a control circuit board, and the solar battery panel and the lithium battery control circuit board are electrically connected , the light touch button, the high-power LED light and the energy storage lithium battery are electrically connected.

Further, the solar cell panel is a monocrystalline silicon solar cell, which is encapsulated by epoxy resin dispensing process.

Further, the light touch button has a multi-stage brightness adjustment function, which controls the brightness of the high-power LED lamp to be 100%, 75%, 50% and 25% respectively.

The invention has the advantages of adopting solar energy as energy supply, energy saving and environmental protection. The design of the bottle button adjustable bracket can conveniently choose the appropriate angle and position to charge the solar panel, and at the same time, it can also adjust the lighting direction of the LED light. The Mini USB input port also provides another way to charge the lithium battery, avoiding the situation of insufficient solar energy.

detailed description

Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

Example

Referring to Fig. 1 and Fig. 2, a kind of multi-functional solar energy portable power supply comprises shell 1, and the bottom of described shell 1 is movably connected with the bracket 2 of adjustable foldable structure, and the center of described bracket 2 is provided with circular hole 10; The front of the shell 1 is provided with light touch buttons 3 and two symmetrically distributed high-power LED lights 4; one side of the shell 1 is provided with a 5V Mini USB input port 5, and the other side is provided with a 5V USB output port 6; The back of the shell 1 is equipped with a solar panel 7; the back of the shell 1 is also provided with a solar charging LED indicator 8; the top of the shell 1 is provided with a battery power LED indicator 9; the inside of the shell 1 An energy storage lithium battery and a control circuit board are also provided, the solar panel 7 is electrically connected to the lithium battery control circuit board, and the light touch button 3, the high-power LED lamp 4 is electrically connected to the energy storage lithium battery.

Among them, the solar cell panel 7 is a monocrystalline silicon solar cell with a conversion efficiency of more than 17%, encapsulated by an epoxy resin glue-dropping process, with a size of 100×60mm and a power of 750mW. The energy storage battery is a single 3.7V rechargeable lithium battery with a capacity of 2200mAH. The light touch button 3 has a multi-stage brightness adjustment function, and controls the brightness of the high-power LED lamp 4 to be 100%, 75%, 50% and 25% respectively. High-power LED lamp 4, the power of each lamp bead is 1/2W, adopts constant current driving mode.
