Description

A kind of black film for rear auto window frame corner

Technical field

This utility model is related to Automobile Products field, more particularly, to a kind of black film for rear auto window frame corner.

Background technology

Black film, also known as hiding black film (blackout film), belongs to one kind of feature automobile adhesive film, used in the vehicle body of automobile The positions such as a, b, c post, window frame, replace paint to play role in decoration, can expand the vision of vehicle window, windshield.However, with this The widely using of one decorative element, the problem brought therewith also becomes increasingly conspicuous.Particularly as follows: on assembly line, black film is pasted on When on rear auto window frame, because rear window frame corner cambered is larger, easily had a rebound tilt problems by film stretch effects itself, serious shadow Ring productive temp and sticking Quality, cause no small puzzlement to user.

Utility model content

For the deficiencies in the prior art, this utility model be intended to provide a kind of solve above-mentioned technical problem for vapour The black film of window frame corner after car, makes original rear auto window upper frame edge black film bounce-back this problem that warps along after bound edge thoroughly be changed Kind.

For achieving the above object, this utility model adopts the following technical scheme that

A kind of black film for rear auto window frame corner, including surface film structure, adhesive, release paper, described black film in Big radian angle position is provided with one or more breach, to discharge the internal stress of black film itself.

Preferably, described breach is u v notch v.

Preferably, the quantity of described breach is 15.

Preferably, the radius of described u v notch v is 1mm, and the distance between two breach is 6.2mm, projection between two breach Height be 2.3mm.

The beneficial effects of the utility model are at least as follows:

This utility model passes through to arrange one or more u v notch vs in the big radian angle position of black film, by black film itself Internal stresses release fall, make material during bound edge, seldom have stretching to black film itself herein, so can in the position of bound edge Effectively prevent the problem that material bounce-back warps.

Brief description

Fig. 1 is used for the overall schematic of the black film of rear auto window frame corner for this utility model.

Fig. 2 is used for the partial schematic diagram of the black film big radian angle position of rear auto window frame corner for this utility model.

Specific embodiment

Below in conjunction with accompanying drawing and specific embodiment, this utility model is described further:

Refer to Fig. 1 and Fig. 2, this utility model relates to the black film of rear auto window frame corner, its big radian corner 1 Install and be equipped with projection 2 and u v notch v 3.

During conventional black film Assembling Production, when monoblock black film is pasted onto according to the size formulated by specific purpose tool After sash position after car door, press lightly on it is necessary to along car door profile in bound edge profile, wrinkle-free to guarantee that black film discharges air Rise, finally pressing makes black film be pasted onto on door-plate completely, and the compacting of black film bound edge region, prevent bounce-back from warping.And using this After the black film for rear auto window frame corner of utility model, because it is provided with 15 radiuses in big radian angle position it is The u v notch v 3 of 1mm, and the distance between two breach is 6.2mm, and between two breach, the height of projection is 2.3mm, by this The internal stresses release of black film itself can be fallen by one design, makes material seldom have stretching to black film itself during bound edge herein, The dependence to film tensile property itself can effectively being reduced, thus avoiding the risk that the black film bounce-back of bound edge position warps, making former The problem that the big radian angle position black film bounce-back coming warps thoroughly is improved.

For a person skilled in the art, can technical scheme as described above and design, make other each Plant corresponding change and deform, and all these changes and deforms the guarantor that all should belong to this utility model claim Within the scope of shield.
