Abstract

The utility model discloses a double glass structure which comprises inner layer glass and outer layer glass. The inner layer glass and the outer layer glass are stacked, and the edge of the inner layer glass and the edge of the outer layer glass are connected as a whole in an adhesive mode so as to form a sealed hollow area between the inner layer glass and the outer layer glass, and the inner sides of the attached edges are provided with a limiting buffering gasket. The double glass structure further comprises a through hole capable of being sealed, and the through hole penetrates through the attached edges and the limiting buffering gasket and directly reaches the hollow area. The double glass structure can effectively isolate noise and improves the NVH effect. Meanwhile, heat exchange between the inner layer glass and the outer layer glass can be effectively isolated, water spray is prevented from condensing in a vehicle, and the situation that glass is frozen when the vehicle is parked for a long time is avoided. Besides, when the glass is hit by stone, a certain buffering function is achieved. When people need to break the glass to escape in an emergency that the vehicle falls into water and other emergency situations, the two layers of thin glass can be broken respectively easily, and the survival probability is improved.

Description

A kind of double-layer glass structure

Technical field

The utility model relates to a kind of glass structure, relates in particular to a kind of double-layer glass structure.

Background technology

Glass is seen everywhere in people's life.

Take vehicle glass as example, along with the increase of automobile pollution, competition between each vehicle.Ordinary consumer, in paying close attention to the factors such as price, economy, safety, is also had higher requirement to traveling comfort.Vehicle glass is generally single-layer medium, NVH(Noise, Vibration to car load, Harshness, i.e. noise, vibration and sound vibration roughness) play vital effect.Part vehicle is in order to improve NVH performance, and by side door glass thickening, but weight also increases simultaneously.How solving this to contradiction, is pendulum problem demanding prompt solution before automobile designers.

Automobile side-door glass is just in time positioned at ear one side, and side door glass stops that the performance of noise is very large on car load NVH impact.If increase side door glass thickness, can gain in weight, improve window regulator load.

In northern automobile, in winter vehicle traveling process, the water smoke that condenses through the vehicle glass inner side of being everlasting, affects the visual field, although front windshield has demist blowing apparatus, effect is limited, and side door glass defogging equipment does not all have.After automobile is placed, vehicle interior temperature meeting in winter step-down, even freezes on glass.

Utility model content

The utility model, for the drawback of prior art, provides a kind of double-layer glass structure.

Double-layer glass structure described in the utility model, comprise inner layer glass and glass outer, described inner layer glass and glass outer stack, and the edge of described inner layer glass and glass outer is bonded together, to form airtight hollow region between described inner layer glass and glass outer; Be provided with limiting buffer packing ring in the inner side at described bonding edge; And also comprise closed through hole, described through hole to wear bonding edge and limiting buffer packing ring and through described hollow region.

In double-layer glass structure described in the utility model, described hollow region is vacuum or is charged unreactable gas.

In double-layer glass structure described in the utility model, described limiting buffer packing ring is rubber cradle or modified plastics packing ring.

In double-layer glass structure described in the utility model, the edge of described inner layer glass and glass outer is bonded together by glass cement.

In double-layer glass structure described in the utility model, in described through hole, be inserted with rubber plug.

In double-layer glass structure described in the utility model, double glass is hollow structure, and effectively noise insulation improves NVH effect; Meanwhile, effectively thermal exchange between isolation glass ectonexine, the water smoke that prevents from condensing in car, while avoiding automobile to place for a long time, glass freezes; And glass has certain buffer action in the time hit by stone; And, if when the emergency situations such as generation vehicle water falling need to destroy glass escape, can break respectively easily two-layer thinner glass into pieces, improve the probability of seeking survival.

The specific embodiment

For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.

As shown in Figure 1 and Figure 2, double-layer glass structure described in the utility model, comprise inner layer glass 2 and glass outer 1, described inner layer glass 2 stacks with glass outer 1, and described inner layer glass 2 is bonded together (being the bonding region 4 in corresponding diagram 2) with the edge of glass outer 1, to form airtight hollow region 6 between described inner layer glass 2 and glass outer 1; Be provided with limiting buffer packing ring 3 in the inner side at described bonding edge; And also comprise closed through hole 5, described through hole 5 to wear bonding edge and limiting buffer packing ring 3 and through described hollow region 6.Described bonding region 4 and limiting buffer packing ring 3 can be positioned at the non-viewing area of glass periphery, and after glass is installed, sealed is waited part to block.

In the utility model, described hollow region 6 can be vacuum or is charged unreactable gas, effectively to completely cut off noise and to prevent the heat transmission between layer glass.

In the utility model, described limiting buffer packing ring 3 can be rubber cradle or modified plastics packing ring, this limiting buffer packing ring 3 plays the effect that keeps spacing between glass outer 1 and inner layer glass 2, in the time that glass is subject to stone and the extraneous impulse force such as hits, has certain buffer action.

In the utility model, described inner layer glass 2 is bonded together by glass cement with the edge of glass outer 2, or also can use other to have the lining cement of no sag phenomenon in enough bind strengths and adhesion process.

In the utility model, in described through hole 5, be inserted with rubber plug, so that vacuumize or be filled with unreactable gas.

Double-layer glass structure described in the utility model is not limited to vehicle glass, as shown in Figure 3, Figure 4, can be processed into as required various specific shapes.

The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
