Description
Technical field
The present invention relates to a kind of dual-mode handset charge protection device, what be specifically related to is a kind of in mobile phone charging process, and the power supply had according to charging the phone is civil power or portable power source, comes to implement different protected modes to these two kinds of power supplys respectively.
Background technology
At present, charger for mobile phone plug is inserted the charging of indoor power supply jack by mobile phone charging usually, or adopts Mobile power charger to be mobile phone charging.Usually, when having phone to come in, people's custom is not pulled out power supply and is just directly received calls, or play games etc. in charging limit, limit, this type of uses the behavior of mobile phone will cause charger full-load operation while mobile phone charging, cause charger to damage electric leakage, even cause user to be electrically shocked time serious dead.
When receiving calls, the control system of electric wave to mobile phone charge control system and charger produces interference, and load adds wave interference charge control module, mobile phone againsts ear, once the disturbed out-of-balance voltage of control module raises electric leakage, electric current is passed by from brain, causes brain cell unusual death.
Safety utilization of electric power poor consciousness, the custom of pulling out charge power supply when not forming good receiving calls can bring personal injury.In order to avoid this type of accident occurs in succession, need when user uses mobile phone to receive calls or plays games, automatically cut off mobile phone charging, to ensure the personal safety of user.
Summary of the invention
Dual-mode handset charge protection device provided by the present invention, has and automatically cuts off civil power when mobile phone changes positive and negative accumbency or the mode of setting, to ensure the fail safe of charging.
The present invention realizes with following technical scheme: a kind of dual-mode handset charge protection device; describedly double modely be: civil power protected mode and portable power source protected mode two kinds; it is characterized in that; civil power protected mode and portable power source protected mode are changed by a switch control rule; it is characterized in that, switch is connected with city's electrical protective device and portable power source protective device.
Further, the jack of protective device inserts for the plug of charger for mobile phone, the plug of protective device for inserting mobile phone,
One grade, switch, during civil power protected mode:
Directly control by an electrode and two electrodes, one electrode is connected with jack, two electrodes are connected with plug, mobile phone is kept flat, sliding ball is slipped to the bottom ports of sliding plate naturally, an electrode bottom conducting and two electrodes, make power supply directly charge the phone or directly turn-on relay or metal-oxide-semiconductor and power supply charges the phone through relay or metal-oxide-semiconductor.
Further, when mobile phone receives calls, after protective device changes into vertical or other orientation, other position of sliding plate run to by sliding ball, and an electrode and two electrodes are thrown off, plug power-off, the electrical safety of available protecting user.
Switch second gear, time portable power source protected mode (vehicle-mounted protected mode):
Further, sliding ball controls ineffective to an electrode of sliding plate bottom ports and two electrodes, and power supply charges to mobile phone through three electrodes, four electrodes, portable power source protective device,
Further; when mobile phone receives calls; mobile phone erect or when not exclusively erectting; when namely simulate incoming call is answered posture or gone the posture of electricity or QQ and the chat of micro-letter, sliding ball goes to tail end mouth along sliding plate, touches logical three electrodes and four electrodes; portable power source protective device is cut off the electricity supply; plug power-off, mobile phone stops charging, thus the Electrical Safety of available protecting user.
Further; described sliding plate can need the angle of inclination of protection to be arranged to different radians or gradient according to protective device; at that rate; when civil power protected mode; protective device surrounding has the angle of inclination of certain limit can also ensure the charging of mobile phone; such effect, when preventing mobile phone from placing on the table, table has the inclination that other small articles causes to mobile phone.
Further; city's electrical protective device and portable power source protective device also can respectively with two socket separate connection; form socket one and socket two; when selecting civil power protected mode; the plug of charger is inserted socket one; during optional m igration power protection pattern, the plug of charger is inserted socket two, carrys out independently to control the independent supply of the front end power supply of civil power protected mode and portable power source protected mode thus.
Further, the middle rusty stain placed anti-blushing agent to ensure sliding ball and cause because service time is long of described protective device and sliding plate; Or electroplating processes is carried out to concentric stroking ball and electrode, to ensure the electric conductivity between sliding ball and electrode; Or anti-blushing agent and electroplating processes synchronous matching.
Further, in order to strengthen the moisture absorption effect of anti-blushing agent, several little logical eye can be increased on sliding plate.
Further, described plug is fixedly connected with protective device, or is arranged to the anglec of rotation being rotationally connected between 0 ° ~ 360 °.
Further, or described plug is that plug-in type connects, and the terminal of plug is difformity, can be used for mating from the jack of different mobile phone, prevents the single coupling that causes of plug limited.
Further, described plug is made up of multiple difform plug, and difform plug can make Plane Rotation after connecting on the protection device, realizes multiple plug and uses with mating of mobile phone jack.
Further, this protective device also directly can be made in the inside of mobile phone, integral with Mobile-phone-shaped; Or after the plug being made in charger, form one with the plug of charger; Or coordinate with portable power source, Mobile phone housing etc.
Further; described two-mode field also can take two independently sliding plate realize respectively controlling the independence of city's electrical protective device and portable power source protective device; each sliding plate is controlled by a sliding ball; and control the angle of the sliding plate of the sliding plate compared with control city electrical protective device of portable power source protective device between 45 ° ~ 135 °; be preferably 90 ° of angles, try to get to the heart of a matter towards jack this.
