Abstract
The utility model relates to a dual-material combining piece which is provided with a metal sheet piece and a plastic sheet piece; both side surfaces of the metal sheet piece are respectively provided with an appearance surface and a connecting surface; the plastic sheet piece is formed on the connecting surface by insert molding; the connecting surface is provided with a jointing part; the jointing part is circularly provided with more than two side plates at intervals; the connecting surface extends and is integrated into the side plates; one end of each side plate is connected on the connecting surface and the other end thereof rotates and extends away from the connecting surface in an inclined way; consequently, when the plastic sheet piece is formed on the connecting surface, the plastic sheet piece wraps the side plates, so that the metal sheet piece and the plastic sheet piece are tightly combined and are not easy to be separated.
Description
Technical field
The utility model relates to a kind of electronic product shell structure, refers to the firm two material conjunctions that combine of metal sheet metal component and plastic cement plate especially.
Background technology
The electronic product development is maked rapid progress; and day by day guiding is light; thin; short; little design concept is main; allow many electronic product (as: mobile phones; notebook computer; PDA) can allow the user be convenient to be easy to carry about with one; yet; in order to allow the user be easy to carry; this electronic product can alleviate the weight of product mostly; the modal practice promptly is in the made metal sheet metal component of sheet metal; connect a thicker plastic cement plate; utilize thicker plastic cement plate to make thin metal sheet metal component have good non-deformability; and can reduce overall weight; and the metal sheet metal component is except protecting the product; can electroplate easily again; outward appearances such as baking vanish are handled, so the shell of most of electronic products uses the metal sheet metal component.
When at present the plastic cement plate is in being arranged at the metal sheet metal component, mostly is greatly, makes the metal sheet metal component can be tightly bonding, but this kind practice has following disappearance and inconvenience with the plastic cement plate in being coated with sticker between the two:
(1) the metal sheet metal component separates production with the plastic cement plate, and machining clearance is numerous and diverse, and cost is promoted.
(2) its volume of sticker sclerosis back can slightly reduce (partially liq volatilization), causes easily between metal sheet metal component and the plastic cement plate and produces the gap, and then reduce the qualification rate of finished product.
(3) owing to need turning in use mostly, lifts electronic product casing, and in turning over the process of lifting, the user is a place of gripping or the moving shell of plate, driving shell turns over and lifts, can make metal sheet metal component and the plastic cement plate power that is distorted, produce the situation of unbalance stress, sticker is broken away from because of twisting resistance produces shell is damaged.
When (four) the metal sheet metal component combines with the plastic cement plate, must wait for the sticker sclerosis, to make process time elongated, cause the inconvenience in the production, and sticker uses required cost higher, easily causes the whole price of electronic product to improve, and then causes consumer's purchase intention to reduce.
Summary of the invention
Main purpose of the present utility model is to be, utilizes the set junction surface of metal sheet metal component, and when making plastics formation plastic cement plate on joint face, metal sheet metal component and plastic cement plate are difficult for producing for combining closely and break away from.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of plate combined structure is provided with metal sheet metal component and plastic cement plate, and metal sheet metal component both side surface has appearance and joint face respectively, and plastic cement plate one side surface is connected in the joint face of metal sheet metal component, it is characterized in that:
The joint face of this metal sheet metal component is provided with the junction surface, and the junction surface annular space is provided with plural side plate, and side plate and metal sheet metal component are integrally formed made, and each side plate one end is connected in joint face, the other end is towards extending away from the oblique rotation of joint face, so that plastic cement plate coated sides plate.
Wherein: this junction surface has plural groups.
Wherein: this side plate utilizes cutting tool to be dug by the joint face rotation and forms.
Wherein: the side plate of this metal sheet metal component in the both sides adjacent with the joint face junction, be provided with wing plate towards the joint face extension respectively, and the wing plate end is connected with joint face.
Wherein: this plastic cement plate forms in the joint face of metal sheet metal component with embedded shoot mode.
Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be:
(1) the utility model when making plastics formation plastic cement plate on joint face, utilizes each side plate at plastic overmold junction surface for utilizing the junction surface, breaks away from so that metal sheet metal component and plastic cement plate combine closely to be difficult for producing.
(2) the utility model is each the side plate annular space setting that utilizes the junction surface, and towards extending away from the oblique rotation of joint face, after making the metal sheet metal component and the plastic cement plate combining, the bearing of trend difference that relies on side plate, can resist bigger distortion power, not break away from and metal sheet metal component and plastic cement plate are produced.
(3) the utility model forms side plate for utilizing cutting tool to dig at joint face, so side plate promptly is the part of joint face originally, is not to utilize crimp to form, so can not change in appearance, can effectively keep the complete of appearance.
(4) because the plastic cement plate takes shape in the joint face of metal sheet metal component for utilize penetrating board with embedded ejaculation (INSERT MOLDING), but therefore effective simplification procedure for processing, and then reduce cost.
