Abstract
The utility model relates to a circuit board shielding structure that charges that cell -phone is wireless, including the PCB board and installing the coil on the PCB board, be provided with power supply circuit and MOS drive circuit on the PCB board, be fixed with the metal covering body on the PCB board, the metal covering body covers in power supply circuit and MOS drive circuit top. The utility model discloses an add the metal covering body alone on power supply circuit and MOS drive circuit, reduced whole PCB board spurious radiation's electromagnetic wave, prevent to form the other part and disturb, improved the reliable stability of whole wireless charger, also make the compatible on -vehicle system that whole wireless charger more can be good.
Description
Technical field
This utility model is related to a kind of mobile phone wireless charging technique to be improved.
Background technology
With reaching its maturity for wireless charging technology, range of application also more and more extensively, mainly with civilian is several years ago
Master is (in terms of mobile phone back splint and smart home), but from the beginning of last year (2015), wireless charging product is made by domestic depot successively
For standard configuration or apolegamy, when wireless charging product actually enters auto parts machinery field, EMC（Electro Magnetic Compatibility Electro
Magnetic Compatibility）Problem is just particularly important.
It is various due to there is wiring board, the power circuit being arranged on wiring board, MOS drive circuit etc. in wireless charger
The components and parts of release electromagnetic wave are present, and easily form interference each other.
Utility model content
The purpose of this utility model be provide it is a kind of can effectively on screened circuit plate electromagnetic wave mobile phone wireless charging wire
Road plate shielding construction.
In order to reach the effect above, this utility model is adopted the following technical scheme that：
A kind of mobile phone wireless charging circuit plate shielding construction, including pcb board and the coil being installed on pcb board, in PCB
Power circuit and MOS drive circuit is provided with plate, a metal cover body is fixed with pcb board, and metal cover body covers in power supply electricity
Above road and MOS drive circuit.
Wherein, semi-surrounding structure of the described metal cover body for metallic plate bending forming, the metal cover body are installed with pcb board
Position has welding foot.
Compared with prior art, this utility model has the advantage that：
This utility model is reduced whole by individually setting up metal cover body on power circuit and MOS drive circuit
Pcb board is prevented from forming miscellaneous part and is disturbed, improve the reliable and stable of whole wireless charger to extraradial electromagnetic wave
Property, also makes the compatible onboard system that whole wireless charger more can be good.
Description of the drawings
Fig. 1 is one preferred embodiment structural representation of this utility model.
Specific embodiment
This utility model is described in further detail below in conjunction with specific embodiment and accompanying drawing.
As shown in figure 1, the present embodiment announcement is to reduce circuit board for mobile phone charging wire road plate shielding construction
The improvement project that components and parts are proposed to the formed electromagnetic wave radiation of outside electronic original part.
Specifically, the mobile phone wireless charging circuit plate shielding construction includes pcb board 1 and the line being installed on pcb board
Circle 2, is provided with power circuit and MOS drive circuit on pcb board 1.
As the electromagenetic wave radiation that power circuit and MOS drive circuit are produced is larger, shadow is produced to 2 grade part of coil easily
Ring.In order to reduce the electromagenetic wave radiation, be fixed with a metal cover body 3 on pcb board 1, metal cover body 3 cover in power circuit and
Above MOS drive circuit, the metal cover body 3 effectively shielded power supply circuit can be radiated with the electromagnetic wave outside of MOS drive circuit, subtracted
The impact to miscellaneous part is lacked.
In the present embodiment, the semi-surrounding structure of designed metal cover body 3 for metallic plate bending forming, the metal cover body 3
There is welding foot 31 with 1 installation site of pcb board, whole metal cover body 3 is fixed on pcb board 1 by welding foot 31.
Although carrying out with reference to embodiments above to description of the present utility model, it is familiar with the art
Personnel can carry out many replacements, modifications and variations, be obvious according to above-mentioned content.Therefore, it is all such
Substitute, improve and change and be included in the spirit and scope of appended claims.
Claims (2)
1. a kind of mobile phone wireless charging circuit plate shielding construction, including pcb board (1) and the coil (2) being installed on pcb board,
Power circuit and MOS drive circuit is provided with pcb board, it is characterised in that be fixed with a metal cover body (3) on pcb board,
Metal cover body is covered in above power circuit and MOS drive circuit.
2. mobile phone wireless charging circuit plate shielding construction according to claim 1, it is characterised in that described metal cover body
For the semi-surrounding structure of metallic plate bending forming, the metal cover body has welding foot (31) with pcb board installation site.
