Description
Technical field
The present invention relates to communication field is and in particular to a kind of radiating, dust-proof, light plastic cell phone rear cover.
Background technology
With the continuous progress of society's science and technology, the raising of people's living standard, the function of mobile phone is stronger and stronger, and intelligent, mobile terminalization more carrys out advanced, the trend of substituted greatly computer.The birth of especially smart mobile phone, feature mobile phone of instead of over completely tightly meets call, the simple functions of transmission information.Smart mobile phone is surfed the Net, receiving and dispatching mail, shopping, financial function, and the powerful application such as game constantly adds thereon, gives mobile phone the function on a lot of computers in the past completely, and industry even publicizes the epoch that the next epoch are mobile Internets.
The thing followed is the powerful central processing unit/CPU of these powerful smart mobile phone fit ons, internal memory, graphic process unit/GPU, and CPU is developed from monokaryon to multinuclear, and memory size is extended from tens earliest M to tens G, installs high-performance GPU etc. additional.But companion's and come be that these electronic devices and components caloric values are increasing.Electronic devices and components generate heat, and not only have influence on components and parts serviceability at that time, also can have a strong impact on components and parts service life.
Because mobile phone is as a kind of carrier of small volume, limit it and can not assemble into the excellent part of a lot of heat dispersions as computer, such as radiating tube of fan, excellent thermal conductivity etc., and mobile phone is as a kind of handheld device, quality is an important indicator it is impossible to allow it to have very big weight.
Cell phone rear cover is significant points of mobile phone radiating, but in order to avoid dust and liquid enter interior of mobile phone and damages components and parts, existing cell phone rear cover is typically designed to enclosed；In addition, the material of cell phone rear cover mostly is the material such as metal, glass, plastics.Wherein, plastic material has some superiority as cell phone rear cover, for example, be easy to the features such as processing, structure design degree of freedom height, light weight, low cost.But high molecule plastic is due to being non-thermally conductive material, the heat that the bonnet so made can not produce mobile phone internal electronic component well comes out, and seriously threatens mobile phone service life.
Current traditional injection moulding molding mode requires the high working of plastics Shortcomings of light weight, presentation quality to some.Up-to-date micro foaming injection moulding mode（MuCell）By being passed through supercritical fluid in traditional injection moulding forming method, make foaming inside melt in mould, ultimately form uniformly single-phase mixed liquor.Its advantage compares traditional injection moulding mode energy loss of weight, shortens molding cycle, reduces injection machine tonnage, can lift product quality simultaneously.
Content of the invention
It is an object of the invention to provide a kind of radiating, dust-proof, light plastic cell phone rear cover, both avoid dust, liquid etc. and damage mobile phone components and parts, also well solve mobile phone heat dissipation problem, the plastic handset bonnet simultaneously processing than traditional injection moulding mitigates weight 5～25%.
A kind of radiating, dust-proof, light plastic cell phone rear cover, including bonnet body, described bonnet body is made up of thermoplastic resin material, the inwall of described bonnet body is passed through boss and is connected with edge layer, cellular aperture is all offered on described bonnet body and edge layer, the central axis of the cellular aperture on described bonnet body and edge layer is crisscross arranged.
Scheme further, all in withdrawing pattern shape, its pattern draft is 0.5 degree～45 degree to the cellular aperture on described bonnet body and edge layer.
A diameter of 0.001～5 millimeter of cellular aperture on described bonnet body and edge layer.
The distance between central axis of cellular aperture on the central axis of cellular aperture on described bonnet body and edge layer is 1～10 times of the cellular aperture radius on bonnet body and the cellular aperture radius sum inlayed on layer.
Generally circular in shape, rectangle, the polygon of cellular aperture on described bonnet body and edge layer or irregular shape.
The height of described boss be 0.1～5 millimeter, boss be shaped as rectangle, cylinder, trapezoidal, polygon or irregular shape.
The material of described edge layer is at least one in thermoplastic resin material, metal or glass.
Described boss and this body by integral forming of bonnet, or boss is integrally formed with edge layer, or boss card sets or is pasted onto bonnet body and inlays between layer.
Described bonnet body and edge layer are all to be processed into by micro foaming injection moulding.
The inwall of the cell phone rear cover body by making in thermoplastic resin material for the present invention connects an edge layer by boss and constitutes, and makes to separate certain space by boss between bonnet body and edge layer, rather than fits tightly together；And it is laid with, on bonnet body and edge layer, the cellular aperture that central axis is crisscross arranged, it is achieved thereby that the purpose of mobile phone radiating, also reached prevention dust, liquid etc. simultaneously and entered interior of mobile phone and damage mobile phone components and parts.Meanwhile, this bonnet body is processed into by micro foaming injection moulding, and the plastic handset bonnet processing than traditional injection moulding mitigates weight 5～25%.
Compared with prior art, possesses advantages below：
1. due to being separated by boss between bonnet body and edge layer, and the cellular aperture all opening up above them, allow interior of mobile phone produce conducting with extraneous, be easy to air circulation, take away heat, solve the bad shortcoming of plastic handset bonnet radiating very well.
2. this cell phone rear cover body, plastics edge layer is processed into by micro foaming injection moulding, compares the plastic handset bonnet mitigation weight 5～25% that traditional injection moulding processes.
3. cell phone rear cover body is by cavernous structure that open up with tapered withdrawing pattern mode, that the outer imperial palace of formation is little with inlaying the cellular aperture opening up on layer.This structure is easy to extraneous dust, liquid will not directly be entered in mobile phone by aperture, but allow dust, liquid as much as possible fall on little hole wall.
4. cell phone rear cover body is assembled together with bonnet edge layer, separate that to have certain space to be allowed to be not to fit tightly together between the two by boss design, this structure is easy to extraneous dust, liquid will not directly enter in mobile phone by aperture, but allow and fall and inlay in space between layer with bonnet in cell phone rear cover main body by the dust of aperture, liquid in cell phone rear cover main body, it is easy to clear up in the future.
5. cell phone rear cover body and edge layer are assembled together by boss, and both stagger upper cellular aperture position, further avoid extraneous dust, liquid enters directly into interior of mobile phone.
