Description
Technical field
The present invention relates to wireless charging technical field, in particular to a kind of multi-thread coil structures of wireless charging transmitting terminal.
Background technique
Wireless charger uses electromagnetic induction principle, carries out the transmitting that energy coupling realizes energy by coil, does not have to pass
The characteristics of charging power cord connection of system.Thus increasingly favored by producers such as mobile phone, tablet computer, smartwatch.It is existing
Multi-coil transmitting terminal, the same multiple coils of coil overlap each other, wherein the coil far from magnetic sheet, since magnetic circuit is long,
Inductance will be relatively relatively low；Close to the coil of magnetic sheet, magnetic circuit is shorter, and inductance can be higher.Coil inductance is inconsistent, relative to same
Circuit structure, multiple coil workings whens will generate the difference in performance.
As the utility model of publication number CN208889440U discloses a kind of wireless transmission coil mould group, including antifreeze plate,
There is first coil body zone and the first wireless charging to identify for first transmitting coil and the second transmitting coil, the first transmitting coil
Area, the second transmitting coil have the second coil body area and the second wireless charging cog region.This wireless transmission coil mould group
The center of first wireless charging cog region is fallen in the second coil body area, since the characteristics of wireless charging cog region is center
The magnetic field strength at place is maximum, and smaller closer to fringe magnetic field intensity, and the central area of the first wireless charging cog region has
Maximum magnetic field strength, the magnetic field that central area generates can pass through the second coil body area.
The prior art is usually multiple coil overlappings, general using the circle for changing coil to reach the consistent inductance of coil
Number is to change inductance size, and the coil remote from magnetic sheet, coil turn is more, the coil close from magnetic sheet, and coil turn is less.But this
The structure of sample is theoretically feasible, is but difficult to accurately hold the number of turns in actual production, causes the parameters such as inductance still inconsistent.
Relative to same circuit structure, multiple coil workings whens, still can generate the difference in performance.
Summary of the invention
Aiming at the problem that multiple coil performances have differences in the prior art, the present invention provides a kind of transmittings of wireless charging
Multi-thread coil structures are held, are no longer existed in performance by the rearrangement of coil so that each coil is identical at a distance from magnetic sheet
Difference.
It is technical solution of the present invention below.
A kind of multi-thread coil structures of wireless charging transmitting terminal, including magnetic sheet and the consistent coil of at least two specifications, described
Anticipate coil from magnetic sheet most nearby with a distance from it is consistent, any coil it is consistent with a distance from magnetic sheet farthest and every
A coil and magnetic sheet are in consistent included angle, are partly overlapped between adjacent windings.On each coil in the technical program
Each point to magnetic sheet distance, it is all the same at a distance from other coil corresponding points to magnetic sheet so that coil is in the parameters such as inductance
There is no differences.Therefore the difference in performance would not be generated when multiple coil workings.
Preferably, the generation type of the included angle includes: that the one end of bottom coil far from magnetic sheet passes through elasticity branch
Member supports.Elastic supporting member for supporting optical member generally selects spring or the elastic three piece for having certain angle etc. all may be used.
Preferably, further include shell and regulating rod, the shell is equipped with sliding groove, regulating rod abut in shell top with
And coil upper surface, regulating rod both ends connect sliding groove.In certain situations it is desirable to the output performance either line of transmitting terminal
The inductance of circle is adjusted, and the prior art can not be adjusted effectively, therefore how to carry out convenient tune to the output performance of transmitting terminal
Section and an object of the present invention.Here by sliding laterally regulating rod, so that the position that regulating rod is abutted with coil occurs
Variation makes the included angle of coil and magnetic sheet generate variation simultaneously because the presence of elastic supporting member for supporting optical member, and multiple coils at this time
Angle change is synchronous to be carried out, therefore adjusting is more convenient.
Preferably, the both ends of the regulating rod are equipped with contact, the sectional area of contact is less than regulating rod, contact connection sliding
Slot.Without modification such as cross section, regulating rod is easy to skid off from sliding groove, therefore individually separates both ends design contact, and contact extends
To the outside of sliding groove, the movement of regulating rod can be realized by stirring contact.
Preferably, the generation type of the included angle includes: that each coil leans against on adjacent windings, with head and the tail
The mode mutually leaned on forms required included angle.It, can be by way of mutually leaning on from beginning to end, it is no longer necessary to bullet when more for coil
Property supporting element, directly it is fixed go out included angle.
Preferably, the generation type of the included angle includes: that the coil is fixedly connected with shell, coil and magnetic sheet
At required included angle.
Preferably, the included angle is greater than 0 ° and is less than or equal to 45 °.The excessive effective use that will lead to coil of angle
Rate is too low, causes efficiency too low.
Preferably, the quantity of the coil is 5.The coil that 5 head and the tail mutually lean on can form a preferable angle
Structure.
Substantial effect of the invention includes: that each coil is identical as the distance relation of magnetic sheet, so that entire transmitting terminal exists
Difference when work, on each coil nonexistence energy；Make to can be realized output under specific circumstances additionally by regulating rod
The adjusting of performance, it is convenient and efficient, meet the needs of under different situations, operation strategies are wide.
