Description

A kind of vehicle intelligent USB fast charging device based on type-C interface
Technical field
The utility model relates to a kind of intelligence USB fast charging device, especially a kind of vehicle intelligents based on type-C interface USB fast charging device.
Background technique
With popularizing for the intelligent movables equipment such as smart phone, people are increasingly dependent on smart machine in daily life Help in life, work, meanwhile, also become essential in people's daily life for these intelligent movable equipment charges Activity.Present automobile equipment is in design production, and also using USB power supply interface as standard configuration, traditional USB interface is accounted for With space it is big, need to distinguish front and back sides, plug is not very convenient, and only 4 pins will cause once there is poor contact Entire interface can not work normally.Existing vehicle-mounted USB charging unit, lacks intelligentized quick-charge function, can not be accurate Judge the existing electricity of the battery of access device and is electrically charged the maximum charge load voltage of equipment.
Utility model content
In order to overcome the problems, such as that existing USB charging module charging is slow, interface occupied space is big, plug is inconvenient, this reality With newly providing a kind of vehicle intelligent USB fast charging device based on type-C interface.
The technical solution adopted in the utility model is: including being electrically charged the battery status of equipment and automatic for intelligent decision Select the fast charge module of optimal charge mode;It is connected for mobile unit connection with control USB fast charging device and usb data Single chip circuit and corresponding driver;For protecting USB fast charging device and mobile unit not by the ESD of electrostatic interference and damage Protective module;For providing the type-C USB interface of charging with data-interface;The fast charge module is separately connected automobile confession Power supply, ESD protective module, single chip circuit, type-C USB interface.
Preferably, BC1.2 charge protocol charging module, built-in DC-DC soft start electricity built in the fast charge module Road, built-in short-circuit protection circuit, type-C USB interface data circuit.
Preferably, DC-DC reduction voltage circuit built in the single chip circuit, built-in charging module driver and charging shape State reading circuit.
The beneficial effects of the utility model are: the USB based on type-C interface, volume is smaller, and USB line is not distinguished positive and negative It inserts, user-friendly, charge power can reach 10W or more, and intelligent decision equipment charge situation realizes intelligent fast charge technology And function, shorten the charging time, meanwhile, data connection can also normally be carried out by the USB interface of type-C, can be used as vehicle-mounted The external growth data interface of one of multimedia equipment, and charged state, control charging can be shown on vehicle-mounted multimedia equipment The switching of mode.
Detailed description of the invention
Fig. 1 is the principles of the present invention block diagram.
Fig. 2 is the circuit theory schematic diagram of the utility model.
Specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model includes to be electrically charged the battery status of equipment for intelligent decision and automatically select The fast charge module of optimal charge mode;The monolithic connected for mobile unit connection with control USB fast charging device and usb data Electromechanical road and corresponding driver;For protecting USB fast charging device and mobile unit not to be protected by electrostatic interference and the ESD of damage Module;For providing the type-C USB interface of charging with data-interface;The fast charge module is separately connected automobile power supply electricity Source, ESD protective module, single chip circuit, type-C USB interface.
Referring to Fig. 1, automobile power source is depressured by DC-DC soft starting circuit, and input voltage is automobile batteries power supply 12V-48V voltage, by FPWM mode by voltage step-down to 5V or 9V, and maximum current limliting 2.1A is exported;DC-DC Soft starting circuit connects the charge mode switching circuit of built-in BC1.2 agreement, passes through short-circuit protection circuit connection type-C USB Interface.
Vehicle-mounted multimedia equipment by bus interface connect single chip machine controlling circuit, single chip machine controlling circuit connection built in The charge mode switching circuit control terminal of BC1.2 agreement, single chip machine controlling circuit pass through data connection circuitry and charging shape respectively State decision circuitry connects short-circuit protection circuit.
Referring to Fig. 1 and Fig. 2, whole equipment is powered by automobile power source, and DC-DC soft starting circuit is in output voltage from 0V The time for being raised to 5.05V is 9ms or so, and soft start function protects the upper punching and undershoot of the voltage of USB port, guarantees USB port voltage Stability.Output voltage has starting steady, and the voltage overshoot and current surge to starting moment have the function of well to inhibit The features such as.
The charge mode switching circuit of BC1.2 agreement can be according to the control of single-chip microcomputer signal, in standard down port SDP, special charging port DCP, charge downlink port CDP three kinds of charging circuits between switch over.
Single chip machine controlling circuit can read the instant voltage and electricity of USB port by charged state decision circuitry in real time Stream, while can detecte the fast charge the agreement whether terminal devices such as the mobile phone to charge or plate are held, according to built in single-chip microcontroller Program extrapolates the battery status of charging equipment, selects optimal charge mode according to pre-set programs, and by present charging situation And charge mode is sent to vehicle carried video equipment by data, vehicle carried video equipment can be with by the specific drivers of installation It shows present USB charged state, and charge mode can be adjusted by artificial notch.
Vehicle-mounted multimedia equipment may be implemented and type-C interface by single chip machine controlling circuit and data connection circuitry Data interconnection makes the terminal devices such as the mobile phone to charge or plate and vehicle-mounted multimedia equipment realize data interconnection.
Short-circuit protection circuit ensure that the safety that whole equipment is protected in charging interface accidental short circuit.
ESD electrostatic impedor built in ESD protective module can be effectively prevented electrostatic and set to charging circuit and other carryings Standby interference and destruction operates normally charging and data linkage function.
The two-sided pin reverse symmetry of type-C USB interface arranges, and small in size, USB interface does not distinguish positive anti-plug, convenient User uses.
