[0001] This application relates to the field of automotive window glass accessories technology, and in particular to a stud and front triangular fixed glass assembly. Background Technology

[0002] Fixed windshield assemblies are non-movable windshields mounted on the vehicle body. They typically include the front windshield assembly, rear windshield assembly, front fixed triangular window assembly, and rear fixed triangular window assembly. The front fixed triangular window assembly refers to the fixed glass located in the A-pillar area of ​​the vehicle.

[0003] like Figure 1 and Figure 2 As shown, the front triangular fixed glass assembly includes a stud 01, tempered glass 02, and injection-molded edging 03.

In order to meet the field of vision range, the stud 01 is arranged on the outside of the glass glue.

[0004] The nail post 01 is located on the outside of the glass sealant. The corresponding connection between the nail post 01 and the side panel 04 of the vehicle body is sealed with EPDM sponge gasket 05. High-pressure water can directly spray the glass mounting holes of the nail post 01 and the side panel 04 of the vehicle body, which may cause water leakage from the glass mounting holes.

[0005] Therefore, how to solve the problem of water leakage from the glass mounting holes of the front triangular fixed glass assembly has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] This application proposes a nail post to solve the problem of water leakage from the glass mounting holes of the front triangular fixed glass assembly. This application also proposes a front triangular fixed glass assembly.

[0007] To achieve the above objectives, this application provides a nail post, comprising:

[0008] Base, used for connection with glass;

[0009] A column, the first end of which is connected to the base, and the second end of which is provided with an elastic claw;

[0010] A bowl-shaped sealing ring is fitted onto the first end of the column and fits against the outer wall of the first end of the column. The bottom of the bowl-shaped sealing ring fits against the base, and the rim of the bowl-shaped sealing ring interferes with and seals against the side panel of the vehicle body, thereby achieving a seal between the bowl-shaped sealing ring and the side panel and isolating the glass mounting hole of the side panel of the vehicle body from the space outside the bowl-shaped sealing ring.

[0011] Preferably, the aforementioned nail post also includes a sealing gasket located within the bowl-shaped sealing ring. The sealing gasket is capable of interfering with the side panel of the vehicle body to seal the glass mounting hole. The thickness of the sealing gasket is at least equal to the depth of the bowl-shaped sealing ring.

[0012] Preferably, in the above-mentioned nail post, the sealing gasket is an EPDM sponge gasket.

[0013] Preferably, in the above-mentioned nail post, the interference between the sealing gasket and the vehicle body side panel is 0.7mm-1.5mm;

[0014] And / or, the interference between the bowl and the side panel of the vehicle body is 0.7mm-1.5mm.

[0015] Preferably, in the above-described nail post, the post body comprises a first columnar segment, a second columnar segment, and a third columnar segment, wherein the diameter of the first columnar segment is larger than the diameter of the second columnar segment, and the diameter of the second columnar segment is larger than the diameter of the third columnar segment.

[0016] The first cylindrical segment is connected to the base, the bowl-shaped sealing ring is fitted on the first cylindrical segment, the sealing gasket is fitted on the second cylindrical segment, and the elastic claw is provided on the third cylindrical segment. The diameter of the circumference of the elastic claw after it is unfolded is larger than the diameter of the second cylindrical segment.

[0018] Preferably, in the above-mentioned nail post, the bowl-shaped sealing ring is a rubber ring.

[0019] A front triangular fixed glass assembly includes a glass and a stud. The glass is connected to the body sheet metal by glass glue. The stud is located outside the space formed by the glass glue. The stud is the stud described in any of the above embodiments. The base of the stud is connected to the glass.

[0020] Preferably, in the aforementioned front triangular fixed glass assembly, the base and the glass are connected by pressure-sensitive double-sided adhesive.

[0021] Preferably, in the aforementioned front triangular fixed glass assembly, the second end of the post is conical.

[0022] The nail post provided in this embodiment includes a base, a post body, and a bowl-shaped sealing ring. The base is used to connect to the glass and is connected to the first end of the post body. The second end of the post body is provided with an elastic claw. The bowl-shaped sealing ring is fitted onto the first end of the post body. The bottom of the bowl-shaped sealing ring can abut against the base, and the opening of the bowl-shaped sealing ring can interfere with and seal against the side panel of the vehicle body, achieving a seal between the bowl-shaped sealing ring and the side panel of the vehicle body, thus isolating the glass mounting hole in the side panel of the vehicle body from the space outside the bowl-shaped sealing ring. The glass is edgeless, and high-pressure water can directly spray the space between the glass and the side panel of the vehicle body. However, the bowl-shaped sealing ring isolates the glass mounting hole from the space outside the bowl-shaped sealing ring. Water sprayed into the space between the glass and the side panel of the vehicle body cannot enter the space inside the bowl-shaped sealing ring, and therefore cannot enter the glass mounting hole, solving the problem of water leakage from the glass mounting hole.

[0037] Please see Figures 3-5 .

[0038] This application discloses a nail post, comprising a base 1, a post body 3, and a bowl-shaped sealing ring 5, wherein,

[0039] Base 1 is connected to glass 2;

[0040] The first end of the column 3 is connected to the base 1, and the second end of the column 3 is provided with an elastic claw 4. The column 3 is perpendicular to the base 1.

[0041] A bowl-shaped sealing ring 5 is fitted onto the first end of the column 3. The bowl-shaped sealing ring 5 is bowl-shaped and has a bowl mouth, a bowl wall, an inner cavity, and a bowl bottom. The bowl bottom of the bowl-shaped sealing ring 5 fits into the base 1 and has a certain thickness. The inner cavity has a certain depth (the depth is the distance between the bowl mouth and the side of the bowl bottom that does not fit into the base 1). The bowl mouth of the bowl-shaped sealing ring 5 faces away from the base 1 and can interfere with and seal with the side panel 6 of the vehicle body, thereby achieving a seal between the bowl-shaped sealing ring 5 and the side panel 6 of the vehicle body, so as to isolate the glass mounting hole of the side panel 6 of the vehicle body from the space outside the bowl-shaped sealing ring 5.

[0042] Interference fit sealing utilizes the minute gap interference between two components (the vehicle body side panel 6 and the cup-shaped sealing ring 5 in this solution) to achieve a seal. When the two components are pressed together, their surfaces adhere tightly due to elastic or plastic deformation, thus preventing media leakage. The advantages of interference fit sealing include effectively improving the fatigue life of the structure and ensuring good sealing performance even under high temperature or high pressure environments. Interference fit sealing typically does not require additional sealing materials, offering a cost advantage.

[0043] Before connecting the fixed glass assembly to the side panel 6 of the vehicle body, the fixed glass assembly is assembled first. The fixed glass assembly includes glass 2 and a nail post. The base 1 of the nail post is connected to the glass 2, and a bowl-shaped sealing ring 5 is fitted on the post body 3 of the nail post.

[0044] When the fixed glass assembly is connected to the vehicle side panel 6, the elastic claw 4 at the first end of the column 3 of the nail first extends into the glass mounting hole. The elastic claw 4 is squeezed by the glass mounting hole and undergoes contraction deformation. After the column 3 has completely passed through the glass mounting hole, the elastic force of the elastic claw 4 is released. The vehicle side panel 6 is limited to the glass 2 by the elastic claw 4. At the same time, the vehicle side panel 6 squeezes the bowl-shaped sealing ring 5. The bottom of the bowl-shaped sealing ring 5 fits with the base 1, and the opening of the bowl-shaped sealing ring 5 interferes with the vehicle side panel 6 to seal, forming a closed space inside the bowl-shaped sealing ring 5, thus isolating the glass mounting hole of the vehicle side panel 6 from the space outside the bowl-shaped sealing ring 5.

[0045] In this design, the bowl-shaped sealing ring 5 does not compress the elastic claw 4. That is, after the bowl-shaped sealing ring 5 is fitted onto the first end of the column 3, the elastic claw 4 is in a released state.

[0046] like Figure 3As shown, after the fixed glass assembly and the vehicle side panel 6 are assembled, the glass 2, base 1, cup-shaped sealing ring 5, and vehicle side panel 6 are arranged in sequence along the insertion direction of the nail post. The glass 2 is an edgeless glass, and high-pressure water can directly spray the space between the glass 2 and the vehicle side panel 6. However, the cup-shaped sealing ring 5 can isolate the glass mounting hole from the space outside the cup-shaped sealing ring 5. The water spraying into the space between the glass 2 and the vehicle side panel 6 cannot enter the space inside the cup-shaped sealing ring 5, and therefore cannot enter the glass mounting hole, thus solving the problem of water leakage in the glass mounting hole.

[0047] In related technologies, the fixed glass assembly uses injection-molded edge-sealed glass. The edge of the injection-molded edge-sealed glass interferes with the side wall of the vehicle body to form a seal, preventing high-pressure water from entering between the glass and the side wall of the vehicle body, thus preventing water leakage from the glass mounting holes. However, injection-molded edge-sealed glass is heavy, and injection molding requires the development of full-size glass injection molds, resulting in high mold opening costs.

[0048] The nail column disclosed in this solution covers the area around the glass mounting hole with a bowl-shaped sealing ring 5, which solves the problem of water leakage in the glass mounting hole. This allows the fixed glass assembly to use edgeless glass, saving the development cost of developing a full-size glass injection mold and reducing the weight of the fixed glass assembly.

[0049] The full-size injection molding edging was removed, and the decorative strip on glass 2 was fixed with pressure-sensitive double-sided adhesive to achieve the same appearance and decorative effect as the water-cutting.

[0050] To further optimize the above technical solution, the nail column disclosed in this solution also includes a sealing gasket 7. The sealing gasket 7 is located in the inner cavity of the cup-shaped sealing ring 5. After the body side panel 6 passes through the elastic claw 4, the body side panel 6 simultaneously presses the sealing gasket 7 and the cup-shaped sealing ring 5. The sealing gasket 7 and the cup-shaped sealing ring 5 both interfere with and seal with the body side panel 6, effectively avoiding the occurrence of water leakage problems in the glass mounting hole.

[0051] The nail post disclosed in this solution has two sealing structures. One is a cup-shaped sealing ring 5 that interferes with the side panel 6 of the vehicle body to form a first seal. The other is a sealing gasket 7 that interferes with the side panel 6 of the vehicle body to form a second seal. By combining the two seals, the reliability of preventing water leakage from the glass mounting hole is improved.

[0052] To ensure that the sealing gasket 7 can fit tightly with the side panel 6 of the vehicle body, the thickness of the sealing gasket 7 may optionally be greater than the depth of the cup-shaped sealing ring 5. It should be noted that the thickness of the sealing gasket 7 is the dimension of the sealing gasket 7 along the axial direction of the column 3, and the depth of the cup-shaped sealing ring 5 is the dimension of the inner cavity of the cup-shaped sealing ring 5 along the axial direction of the column 3.

[0053] In some embodiments, the sealing gasket 7 is an EPDM (Ethylene Propylene Diene Monomer) rubber gasket, which has excellent weather resistance, chemical resistance, aging resistance and elasticity.

[0054] The sealing gasket 7 is not limited to the materials mentioned above; it can also be a sealing gasket 7 made of other materials, without specific limitations here.

[0055] In some embodiments, the interference between the bowl-shaped sealing ring 5 and the vehicle side panel 6 is 0.7mm-1.5mm, and / or the interference between the sealing gasket 7 and the vehicle side panel 6 is 0.7mm-1.5mm.

[0056] Preferably, the interference between the bowl-shaped sealing ring 5 and the vehicle side panel 6, and the interference between the sealing gasket 7 and the vehicle side panel 6, is 1 mm.

[0057] like Figure 3 As shown, the column 3 includes a first columnar segment, a second columnar segment, and a third columnar segment. The first columnar segment, the second columnar segment, and the third columnar segment are coaxial. The diameter of the first columnar segment is larger than the diameter of the second columnar segment, and the diameter of the second columnar segment is larger than the diameter of the third columnar segment.

[0058] The first cylindrical section is connected to the base 1. A bowl-shaped sealing ring 5 is fitted on the first cylindrical section. The bottom of the bowl-shaped sealing ring 5 has a through hole that matches the first cylindrical section. Optionally, the through hole is interference-fitted with the first cylindrical section.

[0059] A sealing gasket 7 is fitted onto the second cylindrical section. The sealing gasket 7 has a through hole that mates with the second cylindrical section. Optionally, the through hole is interference-fitted with the second cylindrical section.

[0060] The third columnar section is equipped with an elastic claw 4. The diameter of the circumference of the elastic claw 4 after it is unfolded is larger than the diameter of the glass mounting hole, so as to ensure that the side panel 6 of the vehicle body can be limited after the elastic claw 4 completely passes through the glass mounting hole.

[0061] The shape of the sealing gasket 7 can be selected in various ways. The shape of the sealing gasket 7 can be the same as that of the cup-shaped sealing ring 5, or the shape of the sealing gasket 7 can be different from that of the cup-shaped sealing ring 5.

[0062] In this design, the diameter of the sealing gasket 7 is smaller than the diameter of the cup-shaped sealing ring 5.

[0063] In some embodiments, the base 1 and the column 3 are integrally formed to reduce the processing difficulty of the nail column and to ensure the overall strength of the nail column.

[0064] Optionally, the nails are manufactured using an injection molding process.

[0065] When the bowl-shaped sealing ring 5 interferes with the side panel 6 of the vehicle body, it will deform. The bowl-shaped sealing ring 5 is made of flexible sealing material. In some embodiments, the bowl-shaped sealing ring 5 is a rubber ring.

[0066] This solution also discloses a front triangular fixed glass assembly, including glass 2 and a nail post. Glass 2 is connected to the body sheet metal by glass glue. The nail post is located outside the space formed by the glass glue. The nail post is the nail post described in any of the above solutions. The base 1 of the nail post is connected to glass 2.

[0067] Since the nail post has the above-mentioned technical effects, the front triangular fixed glass assembly with the nail post also has the same technical effects, which will not be elaborated here.

[0068] The front triangular fixed glass assembly disclosed in this solution, by employing the aforementioned studs, allows the front triangular glass assembly to use edgeless glass, and the studs can be positioned on the outside of the space enclosed by the glass adhesive, thus meeting the field of vision requirements of the front triangular fixed glass assembly. Glass 2 is typically tempered glass.

[0069] After the glass 2 is positioned and installed on the side panel 6 of the vehicle body by nailing the post, the glass 2 is fixed to the body sheet metal by glass glue, thus fixing the glass 2 on the vehicle body.

[0070] In some embodiments, the base 1 and the glass 2 are connected by pressure-sensitive double-sided adhesive 8, which simultaneously bonds to both the base 1 and the glass 2. The pressure-sensitive double-sided adhesive 8 achieves bonding without solvents, heat, or other means when pressure is applied, making it convenient to use and providing a strong connection.

[0071] like Figure 3 , Figure 4 and Figure 5 As shown, the second end of the nail post 3 is conical, which reduces the difficulty of fitting the second end of the nail post with the side panel 6 of the vehicle body.

[0072] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed, and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. The scope of this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described application concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
