Description

Wireless charger

Technical field

The utility model is related to distribution box structure technical field, more particularly to a kind of wireless charger.

Background technology

In recent years, wireless charging technology is increasingly mature, and has become practical with the raising of charge efficiency. and which is mainly real Existing scheme has induction, radio-wave radiation formula, electromagnetic resonance. the scheme of electromagnetic induction and radio-wave radiation formula Because relatively low and higher to application environmental requirement in efficiency of transmission at this stage, still in development.

Content of the invention

The purpose of this utility model is for defect present in prior art, and provides a kind of wireless charger.

For realizing that the purpose of this utility model, the utility model provide a kind of wireless charger, it is characterised in that include Radiating circuit and receiving circuit, the radiating circuit include that switch power module, square wave occur module and H bridge modules, emission lines Circle, the receiving circuit include that receiving coil and rectifying and wave-filtering Voltage stabilizing module, the switch power module are used for being depressured current stabilization, institute Stating square wave and module occurring for input drive signal being provided to H bridge modules, it is exchange that the H bridge modules are used for DC inverter Electricity is simultaneously launched, and the H bridge modules are that H bridge inverters and the square wave occur multivibrator of the module for NE555.

Wherein, the H bridges are the H bridges of four power MOS pipes.

Compared with prior art, the beneficial effects of the utility model are, compared with most of one-to-one wireless charging schemes, The design interior in a big way simultaneously can power to multiple mobile devices one. the set system after tested can steady operation, and can Power to mobile phone, three wireless devices of keyboard and mouse simultaneously, reach design requirement.

Description of the drawings

Fig. 1 show the utility model structural representation；

Fig. 2 show circuit theory diagrams of the present utility model.

Specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place The specific embodiment of description only in order to explain the utility model, is not used to limit the utility model.

It should be noted that " connection " described herein and the word for expressing " connection ", such as " being connected ", " being connected " etc., both included that a certain part was directly connected to another part, and also included a certain part by miscellaneous part and another portion Part is connected.

It should be noted that term used herein above is merely to describe specific embodiment, and be not intended to restricted root Illustrative embodiments according to the application.As used herein, unless the context clearly indicates otherwise, otherwise singulative Be also intended to include plural form, additionally, it should be understood that, when in this manual using belong to "comprising" and/or " bag Include " when, which indicates existing characteristics, step, operation, part or module, component and/or combinations thereof.

It should be noted that the description and claims of this application and the term " first " in above-mentioned accompanying drawing, " Two " it is etc. for distinguishing similar object, without for describing specific order or precedence.It should be appreciated that so using Data can exchange in the appropriate case, so as to presently filed embodiment described herein for example can be with except here Order beyond those of diagram or description is implemented.Additionally, term " comprising " and " having " and their any deformation, it is intended that Be to cover non-exclusive include, for example, contain process, method, system, product or the equipment of series of steps or unit not Be necessarily limited to those steps or the unit that clearly lists, but may include clearly not list or for these processes, side Other intrinsic steps of method, product or equipment or unit.

For the ease of description, space relative terms can be used here, such as " ... on ", " ... top ", " in ... upper surface ", " above " etc., for describe as a part shown in the figure or module or feature and other Part or the spatial relation of module or feature.It should be appreciated that space relative terms be intended to include except part or Different azimuth in use or operation outside orientation of person's module described in figure.For example, if the part in accompanying drawing Or module is squeezed, then be described as " above miscellaneous part or module or construction " or " in miscellaneous part or module or On construction " part or module after will be positioned as " below miscellaneous part or module or construction " or " at other Under part or module or construction ".Thus, exemplary term " ... top " can include " ... top " and " in ... lower section " two kinds of orientation.The part or module can also other different modes positioning (be rotated by 90 ° or in other Orientation), and respective explanations are made to the relative description in space used herein above.

It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase Mutually combine.

As shown in Figure 1 and Figure 2, the utility model provides a kind of wireless charger, including radiating circuit and receiving circuit, The radiating circuit includes that switch power module, square wave occur module and H bridge modules, transmitting coil, and the receiving circuit includes Receiving coil and rectifying and wave-filtering Voltage stabilizing module, the switch power module are used for being depressured current stabilization, and the square wave occurs module to be used for Input drive signal is provided to H bridge modules, the H bridge modules are used for for alternating current and launching, the H bridges mould DC inverter Block is that H bridge inverters and the square wave occur multivibrator of the module for NE555.

Wherein, the H bridges are the H bridges of four power MOS pipes.

A kind of use H bridges of the design and the wireless charging of multivibrator, demonstrate the feasibility of system design.Passing through After actual making and test, as a result show that this design can be with higher efficiency transmission electric energy, peak efficiency reachable about 46%. The novelty of the design is the powering mode of one-to-many, and the product also without same type occurs in the market.
