Description
Technical field
The invention belongs to metallic composite fields, and in particular to a kind of non-crystaline amorphous metal combined housing and its forming method close
Using.
Background technology
The designer trends of electronic product are increasingly to lightweight, function concentration, the smaller direction of volume in the prior art
Development.Conventional material（Such as common stainless steel material and plastic material）As the portion for connecting, fixing, supporting in product
Point, should meet the needs of indexs such as strength impact performance, accomplish as far as possible again lighter and thinner.Requirement for shell is more
Adding strictly, component that should be connected to needs plays the role of fixed, protection, is isolated, and cannot be overweight and excessive occupancy
Space, while wearability and dicoration are had both again.Therefore shell pair a not only light but also with higher-strength hardness is developed
It is very urgent for modern lightweight product.
While lightweight, thinning tendency development, for the electronic product with communication function, more effectively
Send out and receive signal to improve the applicability of product to be also asking of needing to pay close attention to during the exploitation of emerging shell
Topic is then attended trifles and neglect essentials because even use that is ultimate attainment, however but influencing communication function has been accomplished in the slimming of product light weight, nothing
Method obtains the approval of consumer.In most of metal material, since magnetic conductivity is relatively low, so the interference to wireless signal is very tight
Weight（Such as stainless steel material）, and to the more demanding of the fixation of inner components and protection in communication product, it is difficult to use plastics
The shell of class.Then at this stage for fixed and protection inner components, and sending out and receiving for wireless signal is not influenced, often
Using multiple discontinuous metal shells with labyrinth, a large amount of inner space is not only sacrificed in this way, is caused simultaneously
Part processing procedure is complicated, assembling product process increases, and considerably increases production cost height, also makes the volume of product high, difficult
With with competitiveness.Again alternatively, handling the form of plus nano injection molding using complicated multiple tracks CNC cooperations T, process under this mode
Cost significantly increases, and poses a big pressure to integral product cost.
Currently, it is directed to how to realize that metal shell is light-weighted while reducing electromagnetic shielding in the prior art, and can also
Enough this technical problems of reduction technology difficulty do not propose any technique with practicability also.
Invention content
Generated technical barrier is apparently shielding of the metal shell of electronic product to signal in above-mentioned background technology,
But basic influence factor is that the strength of materials is inadequate, and fixed and protection work can not be still played under very thin thickness
With, therefore thickness can only be improved to compensate, and the application of large-sized metal material just can be to signal shielding, therefore have to use
The mode of disconnection is filled in the form of nanometer is molded.In order to solve the deficiencies in the prior art, the present invention provides a kind of profits
The structure of the combined housing made of non-crystaline amorphous metal, the combined housing are not only reduced under conditions of thickness of shell is substantially thinned
Electromagnetic shielding, and still there is the enough shock proof performance of bend resistance, meanwhile, the preparation process of the shell is simply easy
Row is suitble to volume production.
Institute of the invention technique effect to be achieved is realized by following scheme：
The non-crystaline amorphous metal combined housing provided in the present invention, including non-crystaline amorphous metal precast segment and plastic cement coupling unit, it is described

If non-crystaline amorphous metal is designed to product casing according to the characteristics of common metal, in the case of consistency of thickness, make in consumer electronics
It is much superfluous with aspect intensity, and can overall weight be reduced, the influence of most critical is that magnetic signal can be caused
It can not penetrate, to influence the transmitting and receiving of signal.Therefore, to make the characteristic of non-crystaline amorphous metal be fully used, the present invention
It is designed as having the precast segment of thin-wall construction to place in a mold non-crystaline amorphous metal, plastic or other material is injected in the form of being molded
To in mold combined composite structure product is taken out with prefabricated non-crystaline amorphous metal connecting shaping, die sinking.Make non-crystaline amorphous metal
The materials such as precast segment and plastic cement realize that depth is combined, the product of use which be bent or impact and the power that generates
When, the structure mutually supported is formed between non-crystaline amorphous metal precast segment and plastic or other material, to the electronic component of interiors of products
Or other parts form duplicate protection；When the power born is more than the strength degree of plastic or other material, since inside has
The support of non-crystaline amorphous metal, non-crystaline amorphous metal can further keep out impact, to realize the protection to internal structure.Comparison is single
The pure product using plastics as frame, the present invention greatly reduce the probability that product is deformed destruction, are carried to internal structure
For the sustainable upgrading protection used.

Precast segment with thin-wall construction is prefabricated into place in a mold, plastic material is injected into the form of being molded in mold with it is pre-
Combined composite structure product is taken out in the non-crystaline amorphous metal connecting shaping of system, die sinking.The product tool prepared using the present invention
The characteristics of having good electromagnetic signal receiving and emissive porwer, and having benefited from non-crystaline amorphous metal high intensity so that product casing exists
In the case of being significantly thinned, still has the shock proof performance of enough bend resistances, even more considerably reduce the weight of product.This
Non-crystaline amorphous metal combined housing in inventive embodiments has the breakage for falling shock and significantly improves, and especially falls in corner
In the case of improvement it is extremely apparent, better than the Stainless Steel Shell for the same thickness tested under same experimental conditions.
Finally, it should be noted that above example be only to illustrate the embodiment of the present invention technical solution rather than to its into
Row limitation, although the embodiment of the present invention is described in detail with reference to preferred embodiment, those skilled in the art
It should be understood that the technical solution of the embodiment of the present invention can be still modified or replaced equivalently, and these are changed or wait
The range of modified technical solution disengaging technical solution of the embodiment of the present invention cannot also be made with replacement.
