Abstract
Description
Technical Field
[0001] The present application relates to the technical field of automobile glass, and in particular to an edge-wrapped glass assembly. Background Art
[0002] Existing cars are widely equipped with edge-wrapped glass structures. Due to the shrinkage rate of its inherent properties, the edge often shrinks after injection molding. In order to prevent the shrinkage of the edge from having a significant impact on the appearance, the thickness of the edge is often designed to be smaller. The styling design of some car models also has certain requirements on the thickness of the edge, so the thickness of the edge cannot be too thin or too thick. For an overly thick edge, it is necessary to add an insert as a filler in the edge to reduce the thickness of the edge.
[0003] Inserts are usually fixed to the glass in the following ways:
[0004] 1. The insert is clamped on the glass by the claws, but the positioning between the insert and the glass needs to be achieved with the help of tooling, which is costly. At the same time, the claws will occupy the space from the edge of the glass to the sheet metal, which is not conducive to the design;
[0005] 2. The insert is fixed on the glass by adhesive. Usually, the glass ink is marked in advance, and the insert is positioned by the features on the marking line. The positioning is usually done by manual bonding, and the accuracy is poor after bonding, which is not suitable for projects with high precision requirements.
[0006] In the process of realizing the utility model, the inventors found that the prior art has the following problems: the positioning accuracy of the insert and the glass in the existing edge-wrapped glass is poor, and the material flow easily causes the insert to shift during the injection molding edge wrapping. Utility Model Content
[0007] In view of the above problems, it is necessary to provide a glass assembly that is easy to position, so as to solve the problem of poor positioning accuracy of inserts in the prior art.
[0008] To achieve the above objectives, in a first aspect, the present application provides an edge-enclosed glass assembly, comprising:
[0009] The glass comprises an upper surface, a lower surface and a side surface extending between the upper surface and the lower surface; the side surface is provided with a positioning groove;
[0010] The insert is provided with a main body and an extension; the main body protrudes into the positioning groove in the direction of the glass and is matched with the positioning groove; the extension is located at the upper part or the lower part of the main body, and extends from the side of the glass to the inside of the glass on the upper surface or the lower surface of the glass;
[0011] The edge is covered on the edge of the glass, and the insert is covered in the edge.
[0012] Different from the prior art, the above technical solution determines the relative position of the glass and the insert by cooperating with the positioning groove of the glass through the protruding main body, and the extension part extends to the upper surface or lower surface of the glass, so that the position of the insert and the glass in the thickness direction is relatively fixed. This arrangement improves the positioning accuracy between the insert and the glass, facilitates the quick fixation of the insert on the glass, and prevents the material flow from driving the insert to move during the injection molding process. After the injection molding edging process, the edging wraps the glass and the insert together, which is more stable.
[0013] In some embodiments, the main body is an arc-shaped structure, and the arc depth of the main body gradually decreases from the middle to both ends; the positioning groove is an arc-shaped through groove.
[0014] In some embodiments, the maximum arc depth of the main body portion is at least 3 mm.
[0015] In some embodiments, an extension length of the extension portion and the glass is greater than a maximum arc depth of the main body.
[0016] In some embodiments, the upper edge and the lower edge of the side surface of the glass are chamfered.
[0017] In some embodiments, a connecting portion is provided on a side of the main body away from the extending portion, and the connecting portion extends to the chamfer and is adapted to the chamfer.
[0018] In some embodiments, the edging is performed by injection molding to wrap the insert and the glass together.
[0019] In some embodiments, at least a portion of the extension and the contact surface of the glass are coated with an adhesive.
[0020] In some embodiments, a surface of the main body away from the extension portion is flush with a surface of the glass away from the extension portion.
[0021] In a second aspect, the present application provides a vehicle window structure, comprising the enclosed glass assembly as described in the first aspect.
[0022] In a third aspect, the present application provides a vehicle, including a vehicle body and a window structure installed on the vehicle body, wherein the window structure is the window structure described in the second aspect.

[0049] The term "external" denotes an orientation towards the exterior of a vehicle intended to receive a glazing unit according to the invention and the term "interior" denotes an orientation towards the interior of a vehicle intended to receive a glazing unit according to the invention.
[0050] The vehicle body may be any existing structure that needs to be installed with a window structure. The window may be installed on the vehicle body by means of a snap connection or the like.
[0051] In the case of a laminated glazing unit, the glass may be monolithic, that is to say made of a single sheet of material, or composite, that is to say made of a plurality of sheets of material between which at least one layer of bonding material is interposed. The sheets of material may be mineral, in particular made of glass, or organic, in particular made of plastic material. In the case of a glazing unit for a vehicle, the glass generally has a decorative strip (not shown) at least partially on its periphery.
[0052] See also Figure 1-Figure 4 The present embodiment provides an edge-enclosed glass assembly, including glass 1, an insert 2 and an edge 3. The glass 1 has an upper surface, a lower surface and a side surface extending between the upper surface and the lower surface. A positioning groove 11 is provided on the side of the glass 1. The insert 2 is provided with a main body 21 and an extension portion 22, and the main body 21 protrudes into the positioning groove 11 in the direction of the glass 1 and is adapted to the positioning groove 11. The extension portion 22 is located at the upper or lower part of the main body 21, and extends from the side of the glass to the inside of the glass on the upper surface or the lower surface of the glass 1. The edge 3 is coated on the edge of the glass 1, and the insert 2 is coated in the edge 3.
[0053] like Figure 5 As shown, a positioning groove 11 is provided on the side of the glass 1. The positioning groove 11 is a through hole that penetrates the glass 1 along the thickness direction of the glass 1. The positioning groove 11 is provided at the edge of the glass 1, so that the insert 2 can quickly locate the edge of the glass 1 and determine the relative position with the glass 1.
[0054] The insert 2 is a component used to increase the overall strength of the edge-wrapped glass. Specifically, the insert 2 is configured as a plate-like structure with holes, and is made of a material with a certain hardness, such as metal or hard plastic.
[0055] like Figure 6 and Figure 7 As shown, the insert 2 is provided with a main body 21 and an extension 22, and the main body 21 is arranged along the thickness direction of the glass 1. The middle part of the main body 21 protrudes toward the glass 1, matches with the positioning groove 11 at the edge of the glass 1, and can be inserted into the positioning groove 11 to quickly determine the installation position of the insert 2 on the edge, and prevent the insert 2 from moving due to the material flow during the injection molding process.
[0056] The extension portion 22 is disposed at the upper or lower portion of the main body 21, is perpendicular to the main body 21, and extends toward the upper surface or the lower surface of the glass 1. The extension direction is perpendicular to the side surface where the positioning groove 11 is located and away from the main body 11. The extension portion 22 and the main body 21 are integrally formed. The extension portion 22 extends toward the upper surface or the lower surface of the glass 1, which facilitates the rapid positioning of the insert 2 in the thickness direction of the glass 1 and limits the displacement of the insert 2 along the thickness direction.
[0057] The edging 3 is wrapped around the edge of the glass 1, and the insert 2 is wrapped inside the edging 3. The edging 3 only covers the edge of the glass 1, and plays a role in protecting and buffering the edge of the glass 1. The insert 2 is wrapped inside the edging 3, which can increase the thickness and strength of the edging 3.
[0058] The edge wrapping 3 can be made of soft materials, such as TPE or PVC. During the injection molding process, the soft edge wrapping 3 will wrap the insert 2 and the glass together, overcoming the problems of poor edge grinding or edge cracking of the glass 1, and increasing the strength of the glass 1. In addition, the soft material will deform to a certain extent under stress, which can play a certain buffering role.
[0059] Different from the prior art, the above technical solution determines the relative position of the glass 1 and the insert 2 by the protruding main body 21 cooperating with the positioning groove 11 of the glass 1, and the extension part 22 extends to the upper surface or the lower surface of the glass 1, so that the position of the insert 2 and the glass 1 in the thickness direction is relatively fixed. Such a configuration improves the positioning accuracy between the insert 2 and the glass, facilitates the quick fixation of the insert 2 on the glass 1, and prevents the material flow from driving the insert 2 to move during the injection molding process. After the injection molding process, the edge 3 wraps the glass 1 and the insert 2 together, which is more stable.
[0060] In a preferred embodiment, the main body 21 is an arc-shaped structure, and the arc depth of the main body 21 gradually decreases from the middle to the two ends; the positioning groove 11 is an arc-shaped through groove. The arc is a part of a circle or an ellipse. The arc depth is the curvature of the arc. The arc depth of the main body 21 is Figure 7 The arc depth in the middle of the main body 21 is the largest, and the arc depths at both ends gradually decrease.
[0061] The arc shape is currently used to consider the actual glass forming process. Without considering the glass forming process, the main body 21 can also adopt some other shapes. Without limitation, the shape of the main body 21 can be a triangle, a square, or a trapezoid.
[0062] The main body 21 adopts an arc-shaped structure, and the positioning groove 11 also adopts the same shape, and the two are adapted to each other. The main body 21 and the positioning groove 11 are both arc-shaped, which not only meets the process requirements of actual production molding, but also facilitates mutual matching and positioning, avoiding the situation where the insert 2 and the glass wear each other due to the use of some sharp shapes, affecting the positioning accuracy of the main body 21 and the positioning groove 11.
[0063] In some other embodiments, the maximum arc depth of the main body 21 is at least 3 mm. The maximum arc depth of the main body 21 is at least 3 mm, so that the main body 21 and the positioning groove 11 can achieve a good matching effect and ensure the positioning accuracy of the main body 21. If the maximum arc depth of the main body 21 is small, the curvature of the positioning groove 11 is correspondingly small, and the positioning efficiency and positioning accuracy are poor.
[0064] In some other embodiments, the extension length of the extension portion 22 along the extension direction is greater than the maximum arc depth of the main body 21. The extension direction is perpendicular to the side surface where the positioning groove 11 is located and away from the main body 11. The extension portion 22 extends in the extension direction, and the extension length is Figure 7 The extension length α of the extension portion 22 is greater than the maximum arc depth β of the main portion 21, so that the extension portion 22 is more prominent than the main portion 21, increasing the contact area between the insert 2 and the glass 1 and improving the matching stability between the glass 1 and the insert 2.
[0065] In some other embodiments, the upper and lower edges of the side of the glass 1 are chamfered. Since defects such as edge cracking are easily generated when the edge of the glass is at a right angle, the upper and lower edges of the glass are chamfered to reduce the defect rate of the glass edge.
[0066] like Figure 3 As shown, in some other embodiments, a connecting portion 211 is provided on one side of the main body 21 away from the extension portion 22, and the connecting portion 211 extends in the chamfer direction, extends to the chamfer, and matches the chamfer. Specifically, an extension portion 22 is provided on one side of the main body 21, and a connecting portion 211 is provided on the other side. The connecting portion 211 extends in the chamfer direction, extends to the chamfer, and its shape matches the shape of the chamfer. Through the cooperation between the connecting portion 211 and the chamfer, the main body 21 can better fit the edge of the glass 1.
[0067] like Figure 8 As shown, in some other embodiments, at least a portion of the bonding surface of the extension portion 22 and the glass 1 is coated with an adhesive 4. Specifically, the adhesive 4 is coated on the bonding surface of the extension portion 22 and the glass 1 to further enhance the bonding force between the insert 2 and the glass 1 and prevent the insert 2 from moving due to the material flow during the injection molding process.
[0068] In some embodiments, the edging 3 is used to integrally enclose the insert 2 and the glass 1 by injection molding. During the injection molding process, the soft edging 3 encloses the insert 2 and the glass 1 together, thereby increasing the strength of the glass 1, improving the stability, and playing a certain buffering role.
[0069] In some other embodiments, the surface of the main body 21 away from the extension portion 22 is flush with the surface of the glass 1 away from the extension portion 22. Figure 3 As shown, the lower surface of the main body 21 is flush with the lower surface of the glass 1. Figure 4 As shown, the upper surface of the main body 21 is flush with the upper surface of the glass 1. Such an arrangement is conducive to the mutual cooperation between the main body 21 and the glass 1, and also facilitates the positioning of the insert 2 and the glass 1 in the mold.
[0070] In a second aspect, the present application provides a vehicle window structure, comprising the enclosed glass assembly as described in the first aspect.
[0071] In a third aspect, the present application provides a vehicle, including a vehicle body and a window structure installed on the vehicle body, wherein the window structure is the window structure as described in the second aspect.
[0072] In order to allow readers to more intuitively understand certain specific implementation methods of the present application, the present application also provides the following examples for readers' reference.
[0073] Installation method: align the main body 21 of the insert 2 and the positioning groove 11 of the glass 1, place them together in the hemming mold for positioning, and then use hemming liquid for integral injection molding, so that the hemming 3 covers the insert 2 and the glass 1, and the insert 2 is tightly fixed to the glass 1 through the hemming 3. The hemming 3 fully wraps the edge of the glass 1 and the insert 2, playing the role of bonding and buffering. The shape and wrapping position of the hemming 3 are not limited here, and can be adjusted according to actual production needs.
[0074] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
