Description
Technical field
The utility model relates to wireless charging technical field more particularly to a kind of loop constructions for applying to wireless charging.
Background technique
In addition to enameled wire or the aerial coil of conducting wire coiling, existing structure is convenient for the antenna flexibly installed further include: gold
Belong to elastic slice antenna, FPC/PCB antenna and LDS antenna.Wherein, metal clips antenna is to be opened by antenna design drawing, and pass through
Mould punching obtains a three-dimensional structure.FPC/PCB antenna is etched on flexible circuit board and hard circuit board respectively
Antenna pattern out, shape pass through what cross cutting came out again.LDS is then to carry out laser laser carving on plastic rubber bracket to go out antenna pattern, so
It is plated afterwards by changing, metal is plated in the region of laser carving and forms antenna.
However, metal clips antenna is although low in cost, but physical fit difficulty is bigger, such as some arcwall faces are difficult to
It is formed by mould punching, but general mobile terminal internal structure is more compact, the space structure used for antenna is more multiple
It is miscellaneous, if it is relatively low to will cause mobile terminal inner space utilization rate using metal clips antenna.PCB antenna compares metal clips
Antenna structure limitation is bigger, can only attach in one plane.FPC antenna can be attached to some arcwall faces because being flexible
Supporting element on, but mount consistency and be relatively difficult to guarantee, and the security risks such as warp there are arcwall face.LDS antenna structure can compare
Relatively flexibly, adhesive force is also stronger, can process in spherical, but complex process, at high cost, and needsization are plated, and have environmental protection
Risk, and plastic rubber substrate is required, it generally requires and just can be carried out processing on specified material.Therefore, the prior art is defective,
It needs to improve.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of coil knot for applying to wireless charging
Structure.
The technical solution of the utility model is as follows: a kind of loop construction applying to wireless charging, including shell, magnetics substrate
And conductive layer；The shell, magnetics substrate and conductive layer successively stack, and the shell is equipped with coarse close to the side of magnetics substrate
Face is coated with metal sloppy heat on the rough surface and penetrates layer, and the metal sloppy heat penetrates layer and forms coil.
Further, the coil is " returning " character form structure, in the gap of " time " the font coil equipped with not with coil
The thin plate ferrite of contact.
Further, layer choosing group composed by zinc, copper, nickel, cadmium, pltine and the corronil is penetrated in the metal sloppy heat
One of group.
Further, the conductive layer is mainboard, metal plate or battery.
Using the above scheme, the utility model structure is simple, facilitates processing, and coil is easy to make, can effectively reduce coil
The dispersion loss at back has good magnetic field shielding effect；The utility model is penetrated layer as coil using metal sloppy heat and is adhered to
On the shell, low in cost, material environmental protection, enclosure material and shape using flexible, wire coil can be significantly greatly increased with object figuration
The flexibility of structure.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, the structure that can also be shown according to these attached drawings obtains other attached drawings.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the cross-sectional view of casing part structure.
The embodiments will be further described with reference to the accompanying drawings for the realization, functional characteristics and advantage of the utility model aim.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Shown in referring to Figures 1 and 2, the utility model provides a kind of loop construction for applying to wireless charging, including shell
1, magnetics substrate 2 and conductive layer 3；The shell 1, magnetics substrate 2 and conductive layer 3 successively stack, and the shell 1 is close to magnetics substrate 2
Side be equipped with rough surface 11, metal sloppy heat is coated on the rough surface 11 and penetrates layer 4, the metal sloppy heat penetrates layer 4 and forms line
Circle.As one embodiment, the shell 1 is plastic body.The metal sloppy heat is penetrated layer 4 and be can be selected from zinc, copper, nickel, cadmium, zinc-copper
One of group composed by alloy and corronil.The conductive layer 3 is mainboard, metal plate or battery.The present embodiment
In, the conductive layer 3 selects aluminium material as shielding material.The conductivity of aluminium sheet is relatively high, therefore magnetic shield performance is preferable.
Coil can be used the mode that metal sloppy heat is penetrated and be attached on shell 1.After solid metal melting, compressed air is used
Mode high-velocity spray forms it into metal coating as covering substrate in 1 surface of shell.Metal jet temperature is up to 1200-
3000 DEG C, speed is 1.57 times of velocity of sound, spaced apart, and sprayed on material reaches material surface temperature only by high-temperature gasification
Have room temperature (38-42 DEG C), being sprayed-on object material can be metal, glass, ceramics, plastics etc., spraying metal materials molecule with
It is sprayed-on the bonding of object material molecules, achievees the effect that closely to attach between metal coating and material.
The coil is " returning " character form structure, in the gap of " time " the font coil equipped with not with the thin plate of coil contact
Ferrite 5.As one embodiment, injection molding process can be used in shell 1 or process for machining forms accommodating thin plate ferrite 5
Groove 12, then will thin plate ferrite 5 be placed in groove 12 in.The setting alternate with the circle line of coil of groove 12, so that the two of coil
Side is equipped with thin plate ferrite 5, and the magnetic field that coil generates preferentially passes through the direction of thin plate ferrite 5, can reduce leakage field in this way
Phenomenon, and increase the inductance of coil.Thin plate ferrite 5 can guide the magnetic field of coil to flow along thin plate ferrite 5, to subtract
The dispersion in few magnetic field, and then reach poly- magnetic function, improve degree of coupling.
In conclusion the utility model structure is simple, facilitate processing, coil is easy to make, can effectively reduce coil back
Dispersion loss, have good magnetic field shielding effect；The utility model is penetrated layer as coil using metal sloppy heat and is attached to outside
Low in cost on shell, material environmental protection, enclosure material and shape using flexible, wire coil can be significantly greatly increased and finish with object figuration
The flexibility of structure.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
