Description

A mobile power

technical field

The utility model relates to a mobile power supply, which belongs to the technical field of power supplies.

Background technique

Mobile power is a portable charger that integrates power supply and charging functions, which can charge mobile phones and other digital devices anytime, anywhere or standby power. Lithium batteries or dry batteries are generally used as power storage units. The core technology of the mobile power supply is whether the curve of the discharge current and voltage is smooth when charging the mobile phone. This is an important technical indicator that is directly related to whether the charging device will be damaged. This discharge curve test must refer to the authoritative test report of the third party. The quality of mobile power mainly depends on two aspects of the battery core and the protection board. Of course, a power bank is not a one-time device, it can be used repeatedly for more than hundreds of times. Therefore, there must be a charging management system inside the mobile power supply. The charging management system can automatically adjust the charging current according to the voltage of the lithium battery.

Now there are many types of mobile power supplies on the market, which are suitable for all kinds of electronic products. However, there is a very important disadvantage that there is only one data line between the mobile power supply and the electronic device. Then it will bring unnecessary trouble to charging anytime and anywhere. For example, there are too many wires between the power supply and the electronic equipment and they are entangled, because the electronic equipment is not fixed first, and the electronic equipment has poor contact due to bumps.

Utility model content

The technical problem to be solved by the utility model is to provide a mobile power supply capable of storing electricity, inductively charging electronic equipment, and fixing the relative position of the electronic equipment.

In order to solve the above technical problems, the technical solution of the utility model is to provide a mobile power supply, which is characterized in that: it includes a rubber casing, an induction panel is arranged inside the rubber casing, and a charging switch, an indicator light and a USB charging socket are arranged on the side of the induction panel; When charging, the electronic device to be charged is placed on the induction panel inside the rubber casing;

There is a step-down rectification circuit and an electromagnetic wave transmitting circuit inside the induction panel. The USB charging socket is connected to the two input ends of the step-down rectification circuit. The output terminal of the battery is connected to the transmitting coil; the receiving coil is arranged inside the electronic device to be charged, and the output terminal of the receiving coil is connected to the battery of the electronic device; the transmitting coil is connected to the charging switch, and the indicator light is connected to the charging switch, the transmitting coil and the USB charging socket.

Preferably, a rubber and plastic insulation layer is provided on the outside of the transmitting coil.

Preferably, the size of the rubber casing is just enough to hold the electronic device to be charged.

The method of using the mobile power supply provided by the utility model is: when charging the induction panel, connect one end of the USB data line to the computer, and insert the other end into the USB charging socket on the induction panel, the indicator light is on, and it is red, and the induction panel is displayed at this time charging. When the indicator light is on and is green, the sensor panel has been fully charged. Put the mobile phone on the sensing panel, that is, place it in the rubber shell. At this time, the mobile phone will generate an induced current with the sensing panel and is ready to charge, and the rubber shell has relatively fixed it. Then lightly press the charging switch, and the sensor panel will start charging the phone. At this time, the indicator light is on, and it is red. That is, at this time, the stored electric energy in the induction panel will generate a magnetic field through the transmitting coil, so that the receiving coil in the mobile phone will also generate a magnetic field, which will be converted into electrical energy, output from the output end of the receiving coil, and enter the mobile phone battery to play the role of wireless charging. When the sensor panel is fully charged for the mobile phone, the indicator light is on, and it is a green light.

The device provided by the utility model overcomes the deficiencies of the prior art, and has a simple structure and a light and handy volume. It can not only use the data line to charge the computer, but also can use the induction between the electronic device to generate current to charge the electronic device. While charging, the position of the electronic device is relatively fixed, so that it is more convenient, faster and safer for consumers to use.
