Description
Technical field
The utility model is related to technical field of mobile phones, more particularly to a kind of mobile phone protecting case based on NFC.
Background technology
Mobile phone is universal very extensively at present, and regular handset protective shell only has the simple functions of protection mobile phone, though
So there are some mobile phone protecting cases with specific function in the market, for example the mobile phone with some functions such as light-emitting LED displays is protected
Protective case, but these are required for mobile phone or included battery powered, included battery powered to also need to be arranged on mobile phone protecting case again
Charge port, and timing is needed charge, very trouble.
Utility model content
The purpose of this utility model is to provide a kind of luminous mobile phone protections of passive LED based on the wireless continued powers of NFC
Shell.
A kind of mobile phone protecting case based on NFC disclosed by the utility model the technical solution adopted is that：It is a kind of based on NFC's
Mobile phone protecting case, including PCB layer, the PCB layer include NFC chip, main control MCU, LED module, and the NFC chip is equipped with
NFC antenna, the NFC antenna are electrically connected the main control MCU by circuit, and the NFC chip connects institute by universal serial bus
Main control MCU is stated, the main control MCU is equipped with multiple I/O interfaces, and the main control MCU passes through multiple I/O interfaces and the LED module
It is electrically connected.
Preferably, the conversion circuit includes the impulse circuit between the NFC antenna and the main control MCU.
Preferably, the conversion circuit further includes the filtered electrical between the NFC antenna and the main control MCU
Road.
Preferably, the impulse circuit includes pulse switch.
Preferably, the mobile phone protecting case based on NFC further includes protective case outer layer, the protective case outer layer and
Equal tabula rasa layer is equipped between the PCB layer.
Preferably, include drop compound protective layer between the equal tabula rasa layer and the protective case outer layer.
The utility model provides a kind of mobile phone protecting case based on NFC, increases NFC chip and NFC on mobile phone protecting case
Antenna, the NFC antenna in NFC chip absorb the wireless energy of mobile phone surrounding magnetic field, are then converted into constant current by conversion circuit
Power supply persistently gives the power supply of the components such as NFC chip, main control MCU and LED module, without external connection battery, Ke Yishi
The various application functions, such as bluetooth, WIFI function etc. of existing NFC chip, may be implemented multiple using NFC wireless power abilities
LED light works at the same time, and keeps being always on state, and LED sends out the light source of strength of stability, and NFC chip can receive communication signal
And feed back to then flash time and frequency that main control MCU controls each LED of LED module.
Description of the drawings
Fig. 1 is the PCB layer electrical block diagram of the mobile phone protecting case based on NFC of the utility model；
Fig. 2 is the structural schematic diagram of the mobile phone protecting case based on NFC of the utility model.
Specific implementation mode
The utility model is further elaborated and is illustrated with reference to specific embodiment and Figure of description：Please refer to figure
1, a kind of mobile phone protecting case based on NFC, including PCB layer 10, the PCB layer 10 include NFC chip U1, main control MCU, LED moulds
Group, the NFC chip U1 are equipped with NFC antenna, and the NFC antenna is electrically connected the main control MCU, the NFC by circuit
Chip connects the main control MCU by universal serial bus, and the main control MCU is equipped with multiple I/O interfaces, and the main control MCU passes through more
A I/O interface is electrically connected with the LED module.The main control MCU can control LED module by way of inside programming
Various flashing lights or bright light combination.
The conversion circuit includes being used for the pulse-triggered of NFC antenna between the NFC antenna and the main control MCU
Signal processing is single-signal impulse circuit and filter circuit, and the filter circuit is further processed transformed electric current, makes
More stablize.The impulse circuit includes pulse switch.When opening mobile phone NFC, main control MCU chip controls pulse switch is beaten
It opens, the wireless energy that NFC antenna absorbs is converted to constant-current supply via impulse circuit, persistently gives other components such as main control MCU
Power supply.
The mobile phone protecting case based on NFC further includes protective case outer layer, between the protective case outer layer and the PCB layer
Equipped with equal tabula rasa layer.The light source that LED is sent out keeps the distribution of light more uniform into after the processing of excessively equal tabula rasa layer, formation and hand
The bright light effect that casing is integrated.
Include drop compound protective layer 30, soft drop compound protective layer between the equal tabula rasa layer 20 and the protective case outer layer
30 can preferably protect equal tabula rasa layer 20.
The utility model provides a kind of mobile phone protecting case based on NFC, increases NFC chip and NFC on mobile phone protecting case
Antenna, the NFC antenna in NFC chip absorb the wireless energy of mobile phone surrounding magnetic field, are then converted into constant current by conversion circuit
Power supply persistently gives the power supply of the components such as NFC chip, main control MCU and LED module, without external connection battery, Ke Yishi
The various application functions, such as bluetooth, WIFI function etc. of existing NFC chip.It may be implemented using NFC wireless power abilities multiple
LED light works at the same time, and keeps being always on state, and LED sends out the light source of strength of stability, and NFC chip can receive communication signal
And then flash time and frequency that main control MCU controls each LED of LED module are fed back to, LED light is realized by main control MCU
The various control function of light, for example, when it is bright when go out breath light effect, recycle different colours marquee effect and fast blink
Colorful lighting effects, to make mobile phone shell have different colours and effect flash model.
Finally it should be noted that above example is only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail to the utility model with reference to preferred embodiment, this field it is general
Lead to it will be appreciated by the skilled person that can be modified or replaced equivalently to the technical solution of the utility model, without departing from this
The spirit and scope of utility model technical solution.
