Abstract
A wireless charger is characterized by comprising an emitter and a receptor. The emitter is used for emitting electromagnetic waves of specific frequency. The receptor is used for receiving specific electromagnetic waves and further producing electric energy. The receptor comprises a receiving coil, a circuit board and an insulating cladding layer which is capable of ensuring safety of personal carry-on electronic products of users during a charging process. The wireless charger enables the charging process to be more convenient, and selection and judgment of polarity effectively protect the charger.
Description
[technical field]
The utility model relates to wireless charger, relates in particular to by reflector, receiver and control circuit to come wireless charger to cell-phone charging.
[background technology]
It is numerous that the wireless charging technology is based on the electronic product that disposes with oneself at present, all need constantly development under the electricity consumption operating position such as mobile phone, MP3, digital camera, the wireless charging technology still is in the budding stage at present, the technology range of application not very extensively, technique effect is also not mature enough, basic scheme is by reflector and receiver are set, and the electromagnetism by between the two carries out energy delivery, reaches the effect of wireless charging.The benefit of wireless technology is mainly aspect several: in the motion, be not subjected to the restriction of electric wire length or exempt the numerous and complicated puzzlement of various electric wires, in the sealing, some electric equipment that need do encapsulation process preferably is exactly to adopt the wireless power technology that send, so the better processing of meeting on the water-proofing treatment, optimal design are being set; Be convenient to do public's infrastructure device, along with the urban planning designs, many forward positions design planning public situation provides wireless charging device as a kind of facilities for the convenience of the people, needs and trend so the development of wireless charging technology can become a kind of technical development.
It in this patent charging at small-sized accompanied electronic product, the problem that solves also only terminates in and be not subjected to the electric wire distance limit when charging in the certain space scope, charging effect is not affected, improve security performance parameter in this technology, such as the use next to the shin at any time of equipment such as mobile phone and MP3, the Electrical Safety problems affect is far-reaching after all.
[summary of the invention]
The utility model has proposed a kind of safe wireless charger at present circumstances, takes into account fail safe under the situation that satisfies distance and charge efficiency.
The technical solution of the utility model is: a kind of wireless charger, it is characterized in that, and comprising:
One reflector is used to launch the electromagnetic wave of characteristic frequency;
One receiver is used to receive specific electromagnetic wave and produces electric energy, and receiver comprises that a receiving coil, a circuit board and an insulating barrier coat;
Also have the polarity selector that to judge the charging end automatically in the described receiver, cause battery impaired in the time of can avoiding the battery polar reversal connection, reaching the effect of charge protection, and then increase the utility model practicality and convenience.
The beneficial effects of the utility model: insulating coating can ensure the fail safe of electronic product when charging of use next to the shin, and wireless charger is convenient by charging process, and polarity selects to judge effectively protection charger.
[description of drawings]
Fig. 1 is the utility model one embodiment principle schematic.
Wherein: 1, reflector; 2, receiver; 2.1, receiving coil; 2.2, circuit board; 2.3, insulating barrier; 2.4, polarity selector.
[embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.
Embodiment 1:
A kind of wireless charger is characterized in that, comprising:
One reflector 1 is used to launch the electromagnetic wave of characteristic frequency;
One receiver 2 is used to receive specific electromagnetic wave and produces electric energy, and receiver comprises that a receiving coil 2.1, a circuit board 2.2 and an insulating barrier 2.3 coat;
Also want the polarity selector 2.4 that to judge the charging end automatically in the described receiver 2, cause battery impaired in the time of can avoiding the battery polar reversal connection, reaching the effect of charge protection, and then increase the utility model practicality and convenience.
Described reflector is used to change electromagnetic frequency, and adjusting to the electromagnetic wave of characteristic frequency, and receiver adopts with the identical frequency of reflector and receives the energy that transmits.Have in addition that insulating barrier does not influence electromagnetic transmission and the insulation of just having carried out preventing leaking electricity.
The beneficial effects of the utility model: insulating coating can ensure the fail safe of electronic product when charging of use next to the shin, and wireless charger is convenient by charging process, and polarity selects to judge effectively protection charger.
