Description

A mobile phone power bank

technical field

The utility model relates to the technical field of charging treasures, in particular to a mobile phone charging treasure.

Background technique

With the rapid development of science and technology, people's living standards are improving day by day, and they often need to carry electronic products to go out for work or travel, among which mobile phones are necessary, and Android phones account for a very large proportion of mobile phones. The battery capacity of Android mobile phones is relatively small, and it consumes a lot of power. It basically runs out of power in less than a day, which brings a lot of troubles to people's daily life, business trips, and travel. Therefore, easy-to-carry mobile power sources are often used as backup power sources to charge electronic products. A power bank refers to a device that can directly charge a mobile device and has its own power reserve unit.

The power of the current charging treasure is limited. After the power is exhausted, it is still necessary to repeatedly charge the charging treasure through an external power supply to store and store electricity. The battery has low energy density and short battery life, and a power adapter is also required for charging. . Just can not charge in the place that does not have power supply when traveling, if add a solar battery on charging treasure, just can charge charging treasure in the place that does not have power supply.

For example, Chinese patent 201220455056.2 provides a mobile phone power bank that can be inserted into the card slot and fixed on the main watch of the power bank, which increases the volume of the power bank. It's inconvenient to hold the phone while on the phone.

For example, Chinese patent 201320433905.9 provides a mobile charging treasure with simple design and single function, and setting two USB output ports increases the burden, and the charging efficiency of the mobile power supply is very low, and the charging current for two mobile phones at the same time is lower, and the charging efficiency is lower. , so only one USB port is enough. Another example is Chinese patent 201320127849.6, which provides a solar charging treasure. Although it can be charged with solar energy when there is no electricity outside, it is still charged with 220V AC when it has electricity indoors, and you still need to carry a power adapter and USB cable when you go out. This leads to troublesome carrying, and you need to look for a charger and a USB cable every time you go out.

Utility model content

The technical problem solved by the utility model is to provide a mobile phone power bank to solve the problems raised in the above-mentioned background technology.

The technical problem solved by the utility model is realized by adopting the following technical solutions: a mobile phone charging treasure, including: a lithium battery and a casing, the lithium battery is arranged in the casing, and buttons, power indicator lights, and lighting lamps are arranged on one side of the casing , USB interface, USB cable, power adapter interface, solar photovoltaic panels are arranged on the upper surface of the casing, the USB cable is placed in the accommodation cavity on one side of the casing, the lithium battery, the control circuit and the DC-DC voltage regulator The output circuit is connected, the power adapter circuit and the solar photovoltaic panel charging circuit are for charging the lithium battery, and the DC-DC voltage regulating output circuit is connected with a lighting lamp and a USB interface.

Compared with the prior art, the beneficial effects of the utility model are:

1) The utility model cleverly combines the solar photovoltaic panel and the charging panel into one, which can also charge the lithium battery when there is no power supply, which solves the trouble of finding the power supply when traveling.

2). The utility model combines the power adapter and the power bank together. It saves the time for users to look for power adapters, and there are many power adapters now, and the charging current varies from large to small. Combining the power adapter and power bank into one can design a DC buck-boost circuit suitable for this power adapter. .

3) The utility model has preset space for placing USB cables on the side. It is convenient to carry the USB cable and charge the mobile phone.

Detailed ways

In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific illustrations.

As shown in Figure 1, a mobile phone power bank includes: a lithium battery, a casing 8, the lithium battery is arranged in the casing 8, and one side of the casing 8 is provided with a button 1, a power indicator light 2, a lighting lamp 3, and a USB interface 4. USB cable 5 , power adapter interface 7 , the solar photovoltaic panel 6 is arranged on the upper surface of the casing 8 , and the USB cable 5 is placed in the accommodation cavity on one side of the casing 8 .

As shown in Figure 2, the lithium battery is connected to the control circuit and the DC-DC voltage regulation output circuit, the power adapter circuit and the solar photovoltaic panel charging circuit are used to charge the lithium battery, and the DC-DC voltage regulation output circuit is connected to the lighting lamp 3, USB Interface 4.

The lithium battery is composed of multiple batteries. The maximum power stored in the power bank depends on the number and capacity of the batteries. The more batteries and the greater the capacity, the greater the power stored in the power bank.

The working principle of the utility model is as follows: the power bank includes a lithium battery and a casing 8, the lithium battery is arranged in the casing 8, and one side of the casing is the socket of a power adapter, which can be directly inserted into a 200V AC slot for charging. On the opposite side is a set of LED indicators to indicate the remaining power of the power bank. The buttons are used to switch modes. When not charging, press the button, the LED indicator will display the power, and double-click the button to turn on the light. The lighting also adopts LED lights, which have low power consumption and high brightness. On the other side is a USB port for charging your phone. On the surface of the charging treasure is a solar photovoltaic panel. Adopt solar photovoltaic panel 6 to absorb solar energy, and the solar energy is replaced into electric energy to charge the battery in the shell 8 .

When traveling, if you cannot find a power source, you can use solar photovoltaic panels to charge the battery. This will be one of the must-have products for those who go out on an adventure. It is also used in daily life. Using solar photovoltaic panels to convert light energy into electrical energy is more environmentally friendly.

Another major feature of the present invention is that there is no need to look for mobile phone charging cables everywhere anymore. A storage space for the USB charging cable is reserved on the power bank. When the time comes, take out the line and use it.

The utility model newly integrates the power adapter module, which makes it necessary to use the power adapter inside the power bank when charging the power bank. Power bank on the market does not have a power adapter, only a USB cable, so you must find a power adapter when charging. There are many kinds of power adapters on the market, including 5V1A, 5V500mA, etc. The smaller the charging current, the slower the charging speed, and the use of different power adapters will inevitably affect the internal circuit of the power bank. The internal power adapter and the corresponding circuit design can effectively improve the charging efficiency and prolong the use time of the power bank. And this is also portable, don't carry a power adapter anymore.

The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above. Those skilled in the industry should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model The new model also has various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The required protection scope of the utility model is defined by the appended claims and their equivalents.
