Description

A kind of windshield

Technical field

The utility model is related to a kind of windshields, belong to door-window glass art.

Background technology

Vehicle glass lightweight already becomes the development trend in the whole world.Relative to other areas, Chinese automobile glass light weight Change and fall behind relatively, at present the windshield glass of automobile thickness 4.96mm of traditional vehicle, area 1.45 ㎡, weight 15.22Kg.

It is mainly used in windshield glass of automobile and side door glass at present, can be derived from now on to all Automobile glass. The windshield glass of sedan-chair race currently on the market all selects lightweight glass to have become trend.

Chinese invention patent application CN201210427931.0 discloses a kind of laminated glass comprising the outer glass surface of annealing Plate and interior glass panel.First polyvinyl butyral（PVB）Layer is disposed adjacent to outer glass panel, and the second PVB layer is arranged For neighbouring interior glass panel.Polyethylene terephthalate（PET）Polymer film be arranged in the first PVB layer and second Between PVB layer.Outer glass panel, the first PVB layer, polymer film, the second PVB layer and interior glass panel link together with shape At laminated glass component.This glass includes five layers, and technique is more complex, and cost is higher, and quality is still laid particular stress on.

Utility model content

The utility model is intended to provide a kind of windshield, the windshield use unsymmetric structure, and inner layer glass compared with Glass outer is thin, can be effectively reduced cost.

To achieve the goals above, technical solution used by the utility model is：

A kind of windshield, including glass outer, inner layer glass, and be arranged between glass outer and inner layer glass PVB glass clamp tunics；It is structurally characterized in that the outer surface of the PVB glass clamps tunic and the inner surface of the glass outer are straight It connects and is fixedly linked, the inner surface of the PVB glass clamps tunic is directly fixedly linked with the inner surface of the inner layer glass；It is described outer The thickness of layer glass is more than the thickness of inner layer glass, and the thickness of the inner layer glass is more than the thickness of PVB glass clamp tunics.

Since the utility model is designed using three-decker, weight is lighter, and technique is simpler, and the thickness of glass outer is big In the thickness of inner layer glass, anti-stone impact property is improved, the heating properties of windshield are improved.

Embodiment according to the present utility model can also make the utility model further optimization, below for optimization after The technical solution of formation：

Preferably, the thickness of the PVB glass clamps tunic is 0.38mm or 0.76mm.

Preferably, the thickness of the inner layer glass is not less than 1.4mm, and is less than 8mm.

Preferably, the thickness of the glass outer is 1.6mm-8mm.

Preferably, the windshield is windshield glass.

Preferably, the thickness of the windshield is 3.96mm.

Compared with prior art, the utility model has the beneficial effects that：

1, lightweight windshield glass significantly reduces the overall weight of automobile, electronic due to automobile lighter overall weight Engine accelerates power to become strong.

3, the utility model enhances optical property.

4, the utility model uses the combination of unsymmetric structure（Glass outer thickness is more than inner layer glass thickness）, windscreen glass The anti-stone impact of glass is more preferable.

5, inner layer glass is thinner, and ghost is fewer, and the imaging effect of HUD is better.

6, the heating properties of windshield are improved, experiment proves, relative to the windshield of traditional vehicle, the utility model Defrosting-defogging time of lightweight glass will reduce 2 minutes.

7. having no to limit for the assembling of automobile component, possess extensive pre-installation ability, even for high standard CBS systems can be coped with easily.

Description of the drawings

Fig. 1 is the longitudinal section structural drawing of the utility model one embodiment.

Specific implementation mode

The utility model is described in detail below with reference to attached drawing and in conjunction with the embodiments.It should be noted that not conflicting In the case of, the feature in the embodiments of the present invention and embodiment can be combined with each other.For sake of convenience, hereinafter such as There are "upper", "lower", "left", "right" printed words, only indicates consistent with the upper and lower, left and right direction of attached drawing itself, not to structure Play restriction effect.

A kind of windshield glass, windshield glass thickness 3.96mm, weight 11.6Kg.Relatively traditional windshield glass, The present embodiment is averaged the windshield glass of per car can be with loss of weight 3.62Kg, while glass is thinning, and safety and comfort are still It remains unchanged.

Windshield glass is suppressed by the inner layer glass of the glass outer of 1.8mm, the PVB originals piece of 0.76mm and 1.4mm. （Glass outer thickness can reach 1.6mm-8mm；Inner layer glass thickness can reach 1.4mm-8mm；PVB glass clamp tunics are by gathering Vinyl butyral resin is extruded from a kind of high molecular material of type through plasticizer DHA plasticizings.PVB glass sandwich film thicknesses Generally 0.38mm and two kinds of 0.76mm has good caking property to unorganic glass, has transparent, heat-resisting, cold-resistant, moisture-proof, The characteristics such as mechanical strength height.PVB film is mainly used for laminated glass, is to be pressed from both sides between two blocks of glass into one layer to contract with polyvinyl alcohol Butyraldehyde PVB film as main component.PVB laminated glass is more due to having safety, heat preservation, control noise and isolation ultraviolet etc. Item function, is widely used in building, automobile and other industries.）

The utility model uses unsymmetric structure（Ectonexine use different thickness and color, the glass outer of 1.8mm and The inner layer glass of 1.4mm）It is particularly important, improve the bendability of glass using technology, to obtain better optical property

The lightweight windshield glass of the utility model can be compatible with multiple functions：Safety, optical, sound-proofing, module Change ability.

The content that above-described embodiment illustrates should be understood as that these embodiments are only used for being illustrated more clearly that the utility model, Rather than limitation the scope of the utility model, after having read the utility model, those skilled in the art are new to this practicality The modification of the various equivalent forms of type each falls within the application range as defined in the appended claims.
