Description

Technical Field

[0001] The utility model relates to the technical field of automobile skylights, in particular to a vacuum glass structure of an automobile skylight. Background Art

[0002] As an indispensable means of transportation in people's daily lives, cars have gradually been given more expectations, and people's demand for cars is not only for driving functions. At present, the panoramic skylight glass of cars has gradually become a trend. It has many advantages such as fashion, good vision, strong sense of technology, space saving, cost saving, etc., but it also brings the problem of heat insulation of large-area skylight glass.

[0003] Most of the heat insulation on the market currently uses PVB film to absorb heat, coating to reflect heat, and sunshade curtains to block heat. Although these methods have a certain degree of heat insulation, the effect is not good. They cannot keep out the sun in summer or keep warm in winter. In winter, the temperature outside the car is low, and the glass inside the car is very easy to fog up, blocking the passengers' sight. In the event of an accident such as a traffic accident, the laminated skylight glass is difficult to break in a short time to complete escape or rescue, which poses a safety hazard.

[0004] For example, Chinese patent CN220146870U discloses a heat-insulating glass and skylight glass; the heat-insulating glass comprises: a first reflective layer, a second reflective layer and a heat-absorbing layer; the second reflective layer, the heat-absorbing layer and the first reflective layer are stacked; the reflectivity of the first reflective layer is greater than the reflectivity of the second reflective layer; the heat-insulating glass is divided into three layers, which are used to reflect light, absorb light and reflect light from the outside to the inside respectively; the light is reflected by the first reflective layer, part of the light is reflected, and the remaining light is transmitted to the position of the heat-absorbing layer, at which time the heat-absorbing layer can absorb part of the light passing through the first reflective layer, and the light passing through the heat-absorbing layer will be reflected by the second reflective layer again, and the second reflective layer can not only isolate the heat-absorbing layer from the occupants, preventing the heat emitted by the heat-absorbing layer after absorbing the light from directly affecting the occupants, but also can finally block the light passing through the heat-absorbing layer. The heat-insulating effect of the skylight glass is limited, which is not conducive to escape or rescue in the event of accidents such as traffic accidents. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a vacuum glass structure for a car skylight, which can achieve better heat insulation / heat preservation / sound insulation / anti-condensation effects.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] The automobile skylight vacuum glass structure comprises a skylight glass body for being arranged on the top of the automobile. The skylight glass body is a hollow vacuum glass, an ink-printed black area is arranged on the vacuum glass, and a pad for positioning and glass mounting glue are arranged inside the vacuum glass.

[0008] Further:

[0009] The vacuum glass comprises an outer glass sheet, an inner glass sheet and a sealing structure at the edge. A vacuum layer is formed between the outer glass sheet and the inner glass sheet, and the thickness of the vacuum layer ranges from 0.1 to 0.5 mm.

[0010] The edge of the vacuum glass is provided with positioning pins.

[0011] The vacuum glass is a curved vacuum automobile skylight glass.

[0012] The outer glass and the inner glass are both made of tempered glass.

[0013] The sealing structure includes sealing solder, a sealing strip and a sealing strip adhesive tape. The outer glass and the inner glass edges are sealed by the sealing solder. The sealing strip wraps the edge and inner side of the vacuum glass. The sealing strip adhesive tape is arranged between the inner side of the inner glass edge and the sealing strip.

[0014] A getter and a group of supports arranged at intervals are arranged between the outer glass and the inner glass.

[0015] The visible light transmittance of the tempered glass is less than 70%, and the glass thickness ranges from 2.0 to 5.0 mm.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] 1. Heat insulation: Thermal radiation can only be transmitted a few hundred nanometers in a vacuum. As long as the glass vacuum belt is made above 1um and combined with dark glass (gray glass / gray film), the thermal radiation energy converted from the electromagnetic radiation of sunlight can be blocked, and TTS (total solar transmittance) can be reduced to less than 10%, which greatly improves the thermal insulation effect of the car and is relatively low in cost.

[0018] 2. Sound insulation: Sound cannot be transmitted in a vacuum, so vacuum skylight glass can greatly improve the sound insulation effect of the entire vehicle;

[0019] 3. Insulation: Vacuum can not only insulate, but also keep warm, reducing the loss of air conditioning in summer and reducing the loss of heat in the car in winter, greatly improving the air conditioning effect, reducing energy consumption, and increasing the vehicle's mileage;

[0020] 4. Anti-condensation: Vacuum glass will not produce fog due to temperature difference, and will not affect the field of view of the skylight glass;

[0021] 5. Escape and rescue: In the event of a traffic accident (door collision and deformation / vehicle falling into water, etc.), the tempered vacuum glass without an intermediate adhesive layer can be broken in a short time to complete escape or rescue, which is of great significance for escape and rescue.

[0027] The specific implementation of the utility model will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.

[0028] like Figure 1 and Figure 2 As shown, the automobile skylight vacuum glass structure includes a skylight glass body for being arranged on the top of the automobile. The skylight glass body is a hollow vacuum glass, and an ink-printed black area 9 and a LOGO mark 14 are provided on the vacuum glass; a pad 10 for positioning and a glass mounting glue 11 are provided on the inner side of the vacuum glass to form an automobile skylight glass assembly 1.

[0029] The vacuum glass is a curved vacuum automobile skylight glass 2; the vacuum glass comprises an outer glass 3 and an inner glass 5 and a sealing structure located at the edge, a vacuum layer 4 is formed between the outer glass and the inner glass, and the thickness of the vacuum layer 4 ranges from 0.1 to 0.5 mm.

[0030] Thermal radiation can only be transmitted a few hundred nanometers in a vacuum. As long as the glass vacuum band is made above 1um and combined with dark glass (gray glass / gray film), the thermal radiation energy converted from the electromagnetic radiation of sunlight can be blocked, and TTS (total solar transmittance) can be reduced to below 10%, greatly improving the thermal insulation effect of the car, and the cost is relatively low. Sound cannot be transmitted in a vacuum, so vacuum skylight glass can greatly enhance the sound insulation effect of the entire vehicle.

[0031] The outer glass 3 and the inner glass 5 are both made of tempered glass; the visible light transmittance of the tempered glass is less than 70%, and the glass thickness ranges from 2.0 to 5.0 mm; if gray glass / green glass is used, it can be tempered to have a certain curvature.

[0032] In the event of a traffic accident (door collision and deformation / vehicle falling into water, etc.), the tempered vacuum glass without an intermediate adhesive layer can be broken in a short time to complete escape or rescue, which is of great significance for escape and rescue.

[0033] Preferably, the sealing structure includes a sealing solder 6, a sealing strip 13 and a sealing strip adhesive tape 15. The edges of the outer glass and the inner glass are sealed by the sealing solder. The sealing strip wraps the edge and inner side of the vacuum glass. The sealing strip adhesive tape is arranged between the inner side of the edge of the inner glass and the sealing strip. The sealing is reliable and can form a protective structure for the edge of the vacuum glass.

[0034] A getter 8 and a set of spaced supports 7 are provided between the outer glass 3 and the inner glass 5; the glass installation glue 11 is located between the pad 10 and the sealing strip adhesive tape 15, and the structure is stable and reliable. A positioning pin 12 is provided at the edge of the vacuum glass, and the positioning pin is arranged corresponding to the edge of the sealing structure, which is convenient for the installation of the automobile skylight glass assembly.

[0035] Moreover, vacuum can not only insulate, but also keep warm. It can reduce the loss of cold air from the air conditioner in summer and the loss of heat in the car in winter, greatly improving the air conditioning effect, reducing energy consumption and increasing vehicle range. Vacuum glass will not produce fog due to temperature difference and will not affect the field of view of the skylight glass.

[0036] The above is only an explanation of the preferred embodiments of the present invention. The above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0037] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
