Description

Technical Field

[0001] The utility model relates to the technical field of bus manufacturing, and particularly relates to a windshield bonding structure and a bus windshield glass. Background Art

[0002] The front windshield glass of a large bus has a complex curved surface streamline shape. The front windshield glass of a vehicle is mainly used to block objects and airflows outside the vehicle from entering the vehicle interior. At present, the front windshield glass of large buses in China is multi-layer laminated glass with a complex curved surface streamline shape. After the vehicle has been running for a period of time, the problem of white flakes at the edges often occurs.

[0003] The inventor found that the following are the main reasons for the white flakes on the glass:

[0004] Refer to the appendix Figure 1 As a traditional bonding structure for bus windshield glass, most of the structural adhesive is applied to the inner porcelain surface during bonding. The side of the glass is narrow and divided into multiple layers. When bonding, the side of the glass is bonded to the sealant. During the installation process, there is a contour error between the glass and the rabbet. Usually, dot fixing is used to clamp the structural adhesive between the rabbet and the inner layer of the glass. There is a certain stress in the inner layer of the glass. In addition, when the vehicle is running, the body twists. As the largest opening, the front windshield is prone to deformation. Eventually, it is reflected that the bonding part on the side of the glass is squeezed. After a long time, cracks are likely to appear between the sealant and the side of the glass. When it rains or the vehicle is washed, water enters the cracks and then slowly soaks into the glass glue layer, resulting in delamination between the glue layer and the glass, and white flakes appear at the edge of the glass. Content of the Utility Model

[0005] The purpose of the utility model is to provide a windshield bonding structure and a bus windshield glass, which can solve the technical problem that cracks and white flakes easily appear at the edges of the existing glass.

[0006] To achieve the above purpose, the utility model proposes a windshield bonding structure, including an inner layer of glass, an outer layer of glass and a rabbet piece. The inner layer of glass is bonded to the outer glass through an adhesive layer. The area of the outer layer of glass is larger than that of the inner layer of glass. The part of the outer layer of glass larger than the inner layer of glass is set as an extended bonding section. At the extended bonding section, the inner layer of glass and the outer glass are simultaneously bonded through a structural adhesive. The structural adhesive and the side of the outer layer of glass are bonded to a sealant, and a windshield rabbet is bonded below the sealant.

[0007] It is further set that the inner side wall of the inner layer of glass is bonded with a structural adhesive, the bottom edge of the inner layer of glass is bonded with a structural adhesive, and the inner side wall of the outer layer of glass is bonded with a structural adhesive.

[0008] It is further set that the area of the inner layer of glass is the same as that of the adhesive layer.

[0009] Further configured such that the sealant is disposed on one side of the structural adhesive and the outer layer of glass, and the sealant bonds the structural adhesive and the outer layer of glass simultaneously.

[0010] Further configured such that the windshield stop includes a corner formed by a horizontal side and a vertical side, and the sealant and the structural adhesive are disposed within the corner.

[0011] Further configured such that the sealant bonds the horizontal side and the vertical side simultaneously.

[0012] Further configured such that the structural adhesive bonds the vertical side.

[0013] Further configured such that the inner layer of glass is centered within the outer layer of glass.

[0014] The present utility model further provides a bus windshield glass, including the aforementioned windshield bonding structure, and a support surface is provided at the lower end of the windshield glass.

[0015] Further configured such that the inner layer of glass and the outer layer of glass corresponding to the support surface are flush at the lower edge of the windshield glass.

[0016] Beneficial effects of the above one or more technical solutions:

[0017] By using different sizes for the inner and outer layers of glass, with the inner layer of glass and the adhesive layer being 5 - 10 mm smaller than the outer layer of glass, when bonding, both the inner and outer layers of glass are bonded to the stop with structural adhesive, improving the torsional strength of the glass. On the side, only the outer layer of glass is bonded to the sealant for the glass. After the structural improvement, the two layers of glass are not easily separated. Even if cracks appear in the sealant seam, moisture cannot enter the glass adhesive layer, strengthening the strength of the glass. Even if cracks appear in the sealant, water will not enter the interlayer to cause the glass to turn white. Description of the Drawings

[0025] The following combines with the attached drawings to illustrate the detailed implementation mode of this embodiment.

[0026] A windshield glass bonding structure, referring to Figure 2 , including an inner layer glass 1, an outer layer glass 2 and a rabbet piece. The inner layer glass 1 is bonded to the outer glass through an adhesive layer 3. The area of the outer layer glass 2 is larger than that of the inner layer glass 1. The part of the outer layer glass 2 larger than the inner layer glass 1 is set as an extended bonding section 21. At the extended bonding section 21, the inner layer glass 1 and the outer glass are simultaneously bonded through a structural adhesive 5. The structural adhesive 5 and the side of the outer layer glass 2 are bonded with a sealant 4, and a windshield rabbet 6 is bonded below the sealant 4.

[0027] The inner side wall of the inner layer glass 1 is bonded with a structural adhesive 5, the bottom edge of the inner layer glass 1 is bonded with a structural adhesive 5, and the inner side wall of the outer layer glass 2 is bonded with a structural adhesive 5. This bonding structure makes only the outer layer glass 2 bonded to the sealant 4. Even if cracks appear, water will not enter the interlayer to cause the glass to turn white.

[0028] The inner layer glass 1 and the adhesive layer 3 have the same area. The sealant 4 is arranged on one side of the structural adhesive 5 and the outer layer glass 2. The sealant 4 simultaneously bonds the structural adhesive 5 and the outer layer glass 2. When bonding, both the inner and outer layer glasses 2 are simultaneously bonded to the rabbet with the structural adhesive 5, improving the torsional strength of the glass.

[0029] The windshield rabbet 6 includes a corner surrounded by a horizontal side and a vertical side. The sealant 4 and the structural adhesive 5 are arranged inside the corner. The sealant 4 simultaneously bonds the horizontal side and the vertical side, and the structural adhesive 5 bonds the vertical side. The bonding structural adhesive 5 simultaneously adheres to the inner layer glass 11 and the outer layer glass 22. The two layers of glass are not easily separated. At the same time, after the bonding structure is connected to the windshield rabbet 6, the inner layer glass 11 and the sealant 4 are bonded into a whole

[0030] The inner layer glass 1 is centered inside the outer layer glass 2. The four side edges of the inner layer glass 1 are offset a certain distance towards the center direction. The inner layer glass 11 and the adhesive layer 3 are 5 - 10 mm smaller than the outer layer glass 22. When bonding, both the inner and outer layer glasses 2 are simultaneously bonded to the rabbet with the structural adhesive 5, improving the torsional strength of the glass. Only the outer layer glass 2 is bonded to the sealant 4 on the side.

[0031] Referring to Figure 3 , this embodiment also provides a bus windshield glass, and a support surface 7 is arranged at the lower end of the windshield glass.

[0032] The inner layer glass 1 and the outer layer glass 2 corresponding to the supporting surface 7 are flush at the lower edge of the windshield glass. For the convenience of transportation and installation, there are two places where the bottom of the glass is flush at 2 / 9 from both ends, which solves the problem that the contact area of the glass is small during transportation, installation and placement, and it is easy to break the edge.

[0033] Although the specific implementation manners of the present invention have been described above in conjunction with the accompanying drawings, it is not a limitation to the protection scope of the present invention. Those skilled in the art should understand that based on the technical solution of the present invention, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the present invention.
