Description

Technical Field

[0001] This application relates to the field of glass technology, specifically to a type of edge-sealed glass. Background Technology

[0002] In automobile manufacturing, various accessories, such as windshield wipers, rearview mirrors, and antennas, need to be installed on the vehicle's glass. Current technology generally involves directly bonding these accessories to the glass. This method requires high-quality adhesives, and their adhesion degrades under high-temperature and harsh environments, making it difficult to maintain the bond for the vehicle's lifespan. Another method involves drilling holes in the glass and securing the accessories with bolts through these holes. However, drilling holes in the glass can lead to edge chipping or poor edge grinding, significantly reducing its strength and impacting its safety performance. Furthermore, directly clamping the glass surface to secure the accessories during installation can cause the glass to crack if the clamping force is too great. Summary of the Invention

[0003] In view of the above problems, there is a need to provide a technical solution to improve the strength of perforated glass, so as to solve the problem that existing perforated glass is prone to edge breakage and affects its strength.

[0004] To achieve the above objectives, in a first aspect, this application provides a cladding glass, comprising:

[0005] A glass body is provided with a first through hole extending through the glass body along a first direction, wherein the first direction is the thickness direction of the glass body;

[0006] Edge wrapping, wrapping the edge of the first through hole;

[0007] The first insert is fixed to the glass body by the edging; the first insert includes a base and an extension, the base is located on one side of the glass body, the extension extends in a first direction and passes through the first through hole, and the extension is provided with a second through hole that passes through the extension in the first direction.

[0008] In some embodiments, a positioning portion is provided on the side surface of the base away from the glass body for positioning an accessory, the accessory being installed in the first insert.

[0009] In some embodiments, the positioning portion is a recessed platform on the side surface of the base away from the glass body.

[0010] In some embodiments, the number of the second through holes is two or more, and the spacing between adjacent second through holes is set.

[0011] In some embodiments, the base is provided with a third through hole, which penetrates the first insert along the first direction. The number of third through holes is multiple, and they are arranged at circumferential intervals along the first insert.

[0012] In some embodiments, the base is provided with a first protrusion, which contacts the glass body; the number of the first protrusions is multiple, and the spacing between them is distributed on the surface of the first insert.

[0013] In some embodiments, it also includes:

[0014] The second insert is located on the side of the glass body away from the base and is disposed opposite to the base; the second insert is provided with a fourth through hole that penetrates the second insert along the first direction, and the second insert is fixed to the glass body by the edging.

[0015] In some embodiments, the second insert is provided with a second protrusion, which contacts the glass body; the number of the second protrusions is multiple, and the spacing between them is distributed on the surface of the second insert.

[0016] In some embodiments, the second insert is provided with a fifth through hole, which penetrates the second insert along the first direction; the number of the fifth through holes is multiple, and they are arranged at circumferential intervals along the second insert.

[0017] In some embodiments, the extension extends in a first direction and passes through the fourth through hole.

[0018] In some embodiments, the diameter of the fourth through hole is 0.5-1 mm larger than the outer diameter of the extension.

[0019] In some embodiments, the edging is achieved by injection molding to integrally cover the first insert, the glass body, and the second insert.

[0020] In some embodiments, the first through hole is a circular hole or an irregularly shaped hole.

[0021] Unlike existing technologies, the above technical solution provides a first insert on one side of the glass body. The first insert disperses the force applied to the first through hole, thereby increasing the strength of the glass. The first insert has an extension at the second through hole. When installing accessories, the clamping force is applied to the extension of the first insert instead of directly to the glass body, thus avoiding excessive clamping force that could cause edge tearing or glass breakage.

[0051] Please see Figure 1 This embodiment provides a type of edge-sealed glass that can be applied to transportation vehicles such as cars, trains, bullet trains, ships, and airplanes, as well as to the construction field, such as doors, windows, and curtain walls.

[0052] The edge-sealed glass includes a glass body 1, an edge 2, and a first insert 3. The glass body 1 has a first through-hole 11 extending through the glass body 1 along a first direction A, where the first direction is the thickness direction of the glass body 1. The edge 2 is used to wrap around the edge of the first through-hole 11. The first insert 3 is fixed to the glass body 1 via the edge 2. The first insert 3 includes a base 31 and an extension 32. The base 31 is located on one side of the glass body 3, and the extension 32 extends in the first direction A and passes through the first through-hole 11. The extension 32 has a second through-hole 321 extending through the extension 32 along the first direction A.

[0053] like Figure 2 As shown, the glass body 1 is provided with a first through hole 11, which can be located in the middle of the glass body 1. The first through hole 11 can also be located at the edge of the glass body 1. In any case, the glass body 1 can be tempered glass, laminated glass, single-layer glass, or double-layer glass.

[0054] Edge banding 2 is a component used to wrap around the glass body 1 and fix the first insert 3 and the glass body 1. Edge banding 2 can be made of soft materials such as TPE, PU, ​​PVC or other materials. During injection molding, the soft edge banding 2 wraps the first insert 3 and the glass body 1 together, overcoming problems such as poor edge grinding or edge bursting of the glass body 1, and increasing the strength of the glass. The edge banding is soft and resilient, allowing for overpressure when the accessories are clamped, and the soft material will deform to a certain extent during the clamping process, providing a larger contact area and playing a certain cushioning role to prevent the accessories and fasteners from loosening due to vibration from vehicle driving after installation.

[0055] like Figure 3 and Figure 4 As shown, the first insert 3 is a component used to increase the overall strength of the edging glass. The first insert 3 can be configured as a perforated plate structure. Specifically, the first insert 3 is made of a material with a certain degree of hardness, such as metal or hard plastic. The first insert 3 is located on one side of the glass body 1, and can be located on the upper or lower side of the glass body 1 in the first direction. The first direction is as follows: Figure 2 As shown by arrow A in the diagram.

[0056] The edging 2 wraps around the first insert 3 and the glass body 1, thus fixing the first insert 3 to the glass body 1. For example... Figure 5As shown, the first insert 3 includes a base 31 and an extension 32, with the base 31 located on one side of the glass body 1. This arrangement allows the base to evenly distribute the clamping force, thereby reducing uneven stress on the glass body 1. The extension 32 extends in a first direction A and passes through the first through hole 11. Specifically, the base 31 and the extension 32 are connected; the base 31 is positioned parallel to the direction of the glass body 1, and the extension 32 is positioned perpendicular to the glass body 1. The extension 32 has a second through hole 42 extending through it along the first direction A. Since the extension 32 extends into the first through hole 11, the force exerted during accessory installation acts on the extension 32, rather than directly on the glass body or the edging.

[0057] Unlike existing technologies, the above technical solution provides a first insert 3 on one side of the glass body 1. The force applied to the first through hole 11 is distributed by the first insert 3, thereby improving the strength of the glass. The first insert 3 is provided with an extension 32. When installing accessories, the clamping force is applied to the extension 32 instead of directly to the glass body 1, thus avoiding excessive clamping force that could cause the edge banding 2 to tear or the glass to break.

[0058] In some other embodiments, a positioning part 33 is provided on the side surface of the base 31 away from the glass body 1 for positioning the position of the accessory, which is used to be installed in the first insert.

[0059] The accessory is used for installation on the first insert 3. The accessory can be, in any case, a windshield wiper, rearview mirror, antenna, bracket, etc. Because the accessory may shift slightly when installed on the glass, resulting in inaccurate positioning, it affects the final installation accuracy. To overcome this problem, a positioning part 33 is provided on the first insert 3 to help position the accessory on the glass, thereby achieving precise installation. Specifically, the positioning part 33 is provided on the surface of the first insert 3 that contacts the accessory. The positioning part 33 can be a protruding structure or a groove structure with a certain shape. The area and shape of the positioning part 33 can be adapted to the shape and size of the accessory, thereby achieving a more precise positioning effect.

[0060] like Figures 3-4 As shown, in some other embodiments, the positioning part 33 is a recessed platform on one side surface of the glass body. Specifically, the positioning part 33 is recessed in the first direction A. The size and shape of the positioning part 33 are adapted to the shape of the accessory. The end face of the accessory that contacts the first insert 3 is recessed into the positioning part 33, which not only helps the accessory to be positioned quickly, but also increases the contact area between the accessory and the glass body 1 and reduces the thickness of the first insert 3.

[0061] In some other embodiments, the base 31 is provided with a first protrusion 34, which contacts the glass body 1. Multiple first protrusions 34 are distributed at intervals on the surface of the first insert 3. The base 31 is provided with the first protrusions 34, which can contact and support the glass body 1. With the first protrusions 34 provided, other parts of the base 31 will always maintain a certain distance from the glass body 1, allowing the edge-sealing liquid to fill the gap between the first insert 3 and the glass body 1, thus reducing the clamping force on the glass body 1. The first protrusions 34 also prevent the first insert 3 from detaching from the edge-sealing 2 and prevent it from shaking up and down during loading and driving.

[0062] like Figure 4 As shown, in some other embodiments, a second insert 4 is also included. The second insert 4 is located on the side of the glass body 1 away from the base 31 and is disposed opposite to the base 31. The second insert 4 has a fourth through hole 42 extending through the second insert 4 along a first direction A, and the second insert 4 is fixed to the glass body 1 by the edging 2.

[0063] like Figure 6 As shown, the second insert 4 is disposed on the side of the glass body 1 away from the base 31. The second insert 4 is fixed to the glass body 1 by the edging 2. Figure 7 As shown, if the first insert 3 is positioned on the upper side of the glass body 1, then the second insert 4 is positioned on the lower side of the glass body 1. Conversely, if the first insert 3 is positioned on the lower side of the glass body 1, then the second insert 4 is positioned on the upper side of the glass body 1. Accordingly, a countersunk platform is provided on the surface of the second insert 4 away from the glass body 1 to facilitate quick and accurate positioning of the accessory. The second insert 4 is made of a material with a certain degree of hardness. The positions of the second insert 4 and the first insert 3 correspond to each other, and they are respectively positioned on both sides of the glass body 1.

[0064] The second insert 4 is provided with a fourth through hole 42 extending through the second insert 4 along the first direction A. Specifically, the fourth through hole 42 may be located at the center of the second insert 4. The fourth through hole 42 is used for passing through an accessory or fastener.

[0065] In some other embodiments, the second insert 4 is provided with a second protrusion 41, which contacts the glass body 1; there are multiple second protrusions 41, spaced apart on the surface of the second insert 4. The second insert 4 is provided with the second protrusion 41, which can support the glass body 1, so that a certain distance is maintained between the glass body 1 and the second insert 4. Specifically, the size and position of the second protrusion 41 correspond to the position of the first protrusion 34, which can better support the glass body.

[0066] In some other embodiments, the diameter of the fourth through hole 42 is larger than the outer diameter of the extension 32. This arrangement maintains a certain distance between the extension 32 and the fourth through hole 42, avoiding the influence of tolerances during actual production and facilitating assembly.

[0067] Since the edging will shrink to some extent, if the distance between the second insert 4 and the extension 32 is too large, the edging between the second insert 4 and the extension 32 will shrink significantly, which will also affect the strength and stability of the overall structure. Specifically, the diameter of the fourth through hole 42 is 0.5-1mm larger than the outer diameter of the extension 32, so that the distance between the second insert 4 and the extension 32 is controlled at a reasonable level, which facilitates the flow of the edging liquid into the gap and can also effectively ensure the structural strength and stability of the edging glass.

[0068] In some other embodiments, the second insert 4 is provided with a fifth through hole 43, which penetrates the second insert 4 along the fourth direction. There are multiple fifth through holes 43, which are arranged at circumferential intervals along the second insert 4.

[0069] In some other embodiments, the extension 32 extends in the first direction A and passes through the fourth through hole 42. When the extension 32 extends to the position of the second insert 4, the first insert 3 and the second insert 4 form an "I" shape, resulting in greater structural stability. Specifically, the shape and size of the fourth through hole 42 are adapted to the shape and size of the extension 32. The end of the extension 32 extends to align with the second insert 4.

[0070] In some other embodiments, the first through hole 11 is a circular hole or an irregularly shaped hole. The irregularly shaped hole can be elliptical, square, trapezoidal, etc. The shape of the irregularly shaped hole is designed and adjusted according to actual production needs. Specifically, for example... Figure 8 As shown, the first through hole 11 is an irregularly shaped hole with a certain curvature. The first through hole 11 can be set at the edge of the glass body 1.

[0071] In some other embodiments, the number of second through holes 321 is two or more, and the spacing between adjacent second through holes 321 is set. For example... Figure 8 As shown, the first insert 3 is provided with three second through holes 321. On the one hand, it can be fixed by multiple fasteners, improving the stability of the accessories when installed on the edge glass; on the other hand, the number of second through holes 321 is more than two, and each second through hole 321 can be connected to different accessories, allowing for the installation of more accessories.

[0072] Figure 9 for Figure 8 Cross-sectional view of the glass with a central edging. The base 31 and the second insert 4 are respectively located on both sides of the glass body 1. Figure 9The left edge 2 of the second through hole 321 is connected to the glass body 1, while the right edge is not connected to the glass body 1 and directly wraps the first insert 3 and the second insert 4.

[0073] like Figure 10 As shown, in some other embodiments, the base 31 is provided with a third through hole 35, which penetrates the first insert 3 along the first direction. During injection molding of the edge-sealing liquid, the liquid can flow into the third through hole 35, increasing both the bonding strength between the glass body 1 and the first insert 3 and improving the overall structural strength of the edge-sealed glass. In some other embodiments, there are multiple third through holes 35, spaced circumferentially along the first insert 3.

[0074] In some other embodiments, the edging 2 integrally encapsulates the first insert 3, the glass body 1, and the second insert 4 through injection molding. During the injection molding process, the soft edging 2 encapsulates the first insert 3, the second insert 4, and the glass body 1 together, increasing the strength and stability of the glass, providing a certain cushioning effect, and preventing accessories or fasteners from loosening after installation.

[0075] like Figure 11 As shown, in some other embodiments, the second insert 4 is provided with a third protrusion 44, and there are two or more third protrusions 44, which contact the first insert 3. The third protrusion 44 serves to support the first insert 3 and increase its strength.

[0076] To enable readers to more intuitively understand some specific embodiments of this application, the following embodiments are also provided for reference.

[0077] Installation method: The first insert 3, the second insert 4, and the glass body 1 are placed in the mold of the edging 2 for positioning. The extension 32 of the first insert 3 can be positioned using tooling to improve the installation accuracy of the extension 32. Then, edging liquid is used for injection molding, so that the soft edging 2 covers the first insert 3, the second insert 4, and the glass body 1. The first insert 3 and the second insert 4 are fixed to the glass body 1 by the edging 2. Then, accessories are installed on the first insert 3. The fixing and locking force of the accessories is concentrated on the positioning part 33.

[0078] The edging 2 fully wraps around the edge of the glass body and also wraps around the first insert 3 and the second insert, serving an adhesive and cushioning function. Specifically, the edging 2 can wrap to a position flush with the top surface of the first insert 3, and the height of the edging 2 can also be higher than the height of the first insert 3, such as... Figure 6 As shown. The edging can also be further extended to the upper surface of the base 31, such as... Figure 2As shown. The shape and position of the edging are not limited and can be adjusted according to actual production needs. A countersunk edge can also be provided on the upper or lower surface of the edging for easy nut installation. After the accessory or fastener passes through the second through hole, nuts are installed on both sides of the accessory. The nuts can be quickly and accurately positioned by the countersunk edge on the edging, locking the accessory in place.

[0079] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
