[0002] Glass assemblies such as the side corner windows of vehicles usually use glass plus injection molding to meet the styling and sealing requirements of the entire vehicle. The thickness of the edging will vary for different models or configurations. When the edging is thicker (for example, greater than 5mm), during the injection molding process, after the surface of the edging is cooled and shaped, the inside is still at a relatively high temperature. After being taken out of the mold, the inside continues to cool and produce corresponding shrinkage deformation, which in turn pulls the already cooled and formed surface, resulting in obvious shrinkage marks on the surface of the edging, affecting product quality. Summary of the invention

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0042] In one embodiment, a vehicle is provided, including a vehicle body and a glass assembly 10 mounted on the vehicle body.

[0043] The vehicle body may be any existing structural form that requires the glass assembly 10 to be installed.

[0044] The glass assembly 10 can be installed on the vehicle body by means of snap-fitting or the like.

[0045] like Figure 1 and Figure 4 As shown, specifically, the glass assembly 10 includes glass 100 and an edge-binding structure 200. The edge-binding structure 200 can be used to edge the glass 100 to fix the glass 100. At the same time, there is no shrinkage mark on the surface of the edge-binding structure 200, ensuring the appearance quality of the glass assembly 10.

[0046] like Figure 2 and Figure 5 As shown, more specifically, the edge-encapsulating structure 200 includes a first insert 210 , a second insert 220 and an injection-molded edge-encapsulating 230 .

[0047] The first insert 210 may be made of at least one of PP (Polypropylene), ABS (AcrylonitrileButadieneStyrene plastic), PC (Polycarbonate), PA (Polyamide), SAN (acrylonitrile-styrene copolymer), PBT (Polybutylene terephthalate), POM (Polyformaldehyde), PVC (Polyvinyl chloride), PU (Polyurethane), and other plastic materials. The material density of the first insert 210 may be 0.9 g / mm 3 ~1.5g / mm 3 . The thickness of the first insert 210 can be 1 mm to 9 mm. In addition, the elastic modulus of the first insert 210 can be 1500 MPa to 14000 MPa; the hardness of the first insert 210 can be Shore 45D to Shore 99D. At the same time, the first insert 210 has a first connecting portion 211 and a connecting surface 212 facing the glass 100. In this way, after the first insert 210 is integrally formed by injection molding or the like, the connecting surface 212 can be directed toward the glass 100 and connected to the glass 100, thereby realizing the assembly connection between the first insert 210 and the glass 100.

[0048] It can be understood that the connecting surface 212 faces the glass 100 , which means that the connecting surface 212 is closer to the glass 100 than other parts of the first insert 210 .

[0049] In addition, the connection between the first insert 210 and the glass 100 can be achieved by providing a second adhesive layer (not shown) such as a corresponding adhesive tape or adhesive between the connecting surface 212 and the glass 100, and the connecting surface 212 and the glass 100 are bonded by the bonding effect of the second adhesive layer, thereby bonding the first insert 210 and the glass 100, so that the first insert 210 and the glass 100 are stably and reliably connected and fixed; Figure 5 As shown, a corresponding third connection part 214 may also be provided on the connection surface 212, and a corresponding fourth connection part 110 may be provided on the glass 100, and the first insert 210 may be stably and reliably connected and fixed to the glass 100 through the connection between the third connection part 214 and the fourth connection part 110. Specifically, the third connection part 214 may be a component such as a nail column, a buckle or a plug, and correspondingly, the fourth connection part 110 may be a nail hole matched with the nail column, a slot 2211 matched with the buckle or a plug hole matched with the plug. Of course, in other embodiments, the third connection part 214 and the fourth connection part 110 may be used to connect and fix the first insert 210 to the glass 100, and the connection surface 212 may be bonded to the glass 100 in combination with the second bonding layer, so as to ensure the stability and reliability of the connection between the first insert 210 and the glass 100, and prevent the first insert 210 from moving relative to the glass 100 during the injection molding process of the injection molding edging 230.

[0050] The second insert 220 may be made of at least one of PP (Polypropylene), ABS (AcrylonitrileButadieneStyrene plastic), PC (Polycarbonate), PA (Polyamide), SAN (acrylonitrile-styrene copolymer), PBT (Polybutylene terephthalate), POM (Polyformaldehyde), PVC (Polyvinyl chloride), PU (Polyurethane), and other plastic materials. The material density of the second insert 220 may be 0.9 g / mm 3 ~1.5g / mm 3 Furthermore, the elastic modulus of the second insert 220 may be 1500 MPa to 14000 MPa; the hardness of the second insert 220 may be Shore 45D to Shore 99D. Figure 2 and Figure 5As shown, at the same time, the second insert 220 is coated on the outer side of the first insert 210. The second insert 220 is provided with a second connecting portion 221 that can be connected to the first connecting portion 211. In this way, after the second insert 220 is integrally formed by injection molding or the like, the second insert 220 is coated on the outer side of the first insert 210, and the second connecting portion 221 is connected to the first connecting portion 211, thereby realizing the assembly connection between the second insert 220 and the first insert 210.

[0051] Optionally, the second insert 220 has a preset thickness, so that the outer surface of the second insert 220 does not shrink or deforms very slightly during the molding process.

[0052] Furthermore, in order to avoid shrinkage deformation of the outer surface of the second insert 220 as much as possible, the second insert 220 can be designed to have a moderate and uniform thickness, which can avoid shrinkage deformation of the outer surface during molding as much as possible or minimize shrinkage deformation during molding.

[0053] It is understood that the outer side of the first insert 210 may refer to the side of the first insert 210 facing away from the glass 100 . The outer side of the second insert 220 may refer to the side of the second insert 220 facing away from the first insert 210 .

[0054] The preset thickness can be flexibly designed or adjusted according to actual processing conditions and use requirements, as long as the outer surface of the second insert 220 does not shrink or deform very slightly during the molding process. Figure 3 ), and 1mm≤D≤5mm, so that the outer surface of the second insert 220 will not shrink or shrink very slightly during the molding process. Specifically, D can be 1mm, 2mm, 3mm, 4mm or 5mm, so that the inner and outer moldings of the second insert 220 are substantially consistent during the molding process, and the outer surface will not shrink or shrink very slightly.

[0055] It can be understood that the preset thickness can be a specific thickness value, such as 1mm, 2mm, 3mm, 4mm or 5mm, or a certain thickness range, such as 1mm~2mm or 2mm~4mm. Taking into account the influence of processing errors, within the allowable error range, the second insert 220 can be considered to have a preset thickness.

[0056] In addition, the connection between the first connection portion 211 and the second connection portion 221 can be achieved by snap-fitting, plug-in, etc., as long as the first insert 210 and the second insert 220 are assembled and connected.

[0057] Optionally, one of the first connecting portion 211 and the second connecting portion 221 is provided with a hook 2111 , and the other is provided with a slot 2211 , and the first insert 210 and the second insert 220 are connected and fixed by the snap fit between the hook 2111 and the slot 2211 .

[0058] like Figure 3 As shown, in the embodiment of the present application, the first connecting portion 211 is provided with a hook 2111, and the second connecting portion 221 is provided with a slot 2211. Figure 3 As shown, more specifically, the hook 2111 includes a horizontal section 21111 arranged parallel to the glass 100 and an inclined section 21112 inclined to the glass 100 and extending in a direction close to the glass 100. The horizontal section 21111 is connected to the inclined section 21112. Furthermore, when the hook 2111 is inserted into the slot 2211, the inner side wall of the slot 2211 contacts the inclined section 21112, causing the inclined section 21112 and the horizontal section 21111 to undergo elastic deformation until the horizontal section 21111 and the inclined section 21112 are both inserted into the slot 2211. Under the action of the reset force, the inclined section 21112 applies a contact force toward the direction close to the glass 100 to the inner side wall of the slot 2211, thereby making the hook 2111 and the inner side wall of the slot 2211 more firmly connected, thereby achieving a stable and reliable assembly connection between the first insert 210 and the second insert 220, thereby preventing the second insert 220 from being squeezed by the injection plastic flow and moving relative to the glass 100 during the injection molding process of the injection molding edging 230.

[0059] like Figure 3 As shown, in addition, the hook 2111 further includes a vertical section 21113 perpendicular to the glass 100 and extending in a direction away from the glass 100, and the vertical section 21113 is connected to the inclined section 21112 by the horizontal section 21111, so that the inclined section 21112 and the vertical section 21113 are arranged at intervals. Moreover, when the hook 2111 is inserted into the slot 2211, the inner side wall of the slot 2211 contacts the inclined section 21112, so that the inclined section 21112 and the horizontal section 21111 are elastically deformed. When the horizontal section 21111 and the inclined section 21112 are completely inserted into the slot 2211, the end surface 2213 of the slot 2211 can contact and cooperate with the vertical section 21113, so that the assembly of the hook 2111 and the slot 2211 can be limited, and the assembly accuracy between the first insert 210 and the second insert 220 can be ensured.

[0060] like Figure 3As shown, in addition, the second connecting portion 221 is provided with a bonding surface 2212 that is bonded to the glass 100. In this way, when the second insert 220 is assembled and connected with the first insert 210, that is, when the second connecting portion 221 is connected with the first connecting portion 211, specifically, when the hook 2111 is inserted into the card slot 2211, the bonding surface 2212 is bonded to the surface of the glass 100, which can prevent the injection plastic flow from entering the gap between the second insert 220 and the glass 100 during the injection molding process of the injection molding edge 230 and squeezing the air in the gap to lift up the second insert 220 during the pressure holding process, thereby avoiding the problems of the injection molding edge 230 being broken and the second insert 220 being visible due to the lifting of the second insert 220, and ensuring the appearance quality of the edge structure 200.

[0061] At the same time, the inclined section 21112 applies a resistance force toward the glass 100 to the inner wall of the slot 2211, so that the fitting surface 2212 and the glass 100 fit more closely, which can better prevent the injection plastic flow from entering the gap between the fitting surface 2212 and the glass 100.

[0062] Combination Figure 2 and Figure 3 As shown, specifically, two opposite sides of the second connection portion 221 are respectively provided with a slot 2211 and a fitting surface 2212 .

[0063] The injection molding edge 230 may be formed by melting and then cooling the granular material. The hardness of the injection molding edge 230 may be less than the hardness of the first insert 210 or the second insert 220. Figure 3 and Figure 5 As shown, the injection molding edging 230 is constructed to cover the outer side of the second insert 220, and the injection molding edging 230 can be connected to the glass 100, so as to encapsulate the first insert 210 and the second insert 220, that is, the first insert 210 and the second insert 220 are encapsulated between the injection molding edging 230 and the glass 100.

[0064] Specifically, the first insert 210 is connected to the glass 100, and then the second insert 220 is covered on the outside of the first insert 210, and finally the injection molding edging 230 is injection molded on the outside of the second insert 220, so that the injection molding edging 230 can be covered on the outside of the second insert 220, and the injection molding edging 230 is connected to the glass 100, and then the first insert 210 and the second insert 220 are encapsulated between the injection molding edging 230 and the glass 100.

[0065] like Figure 3As shown, the outer surface of the second insert 220 away from the first insert 210 is configured to imitate the outer surface of the injection molding edge 230 away from the second insert 220, that is, the outer contour of the outer surface of the second insert 220 away from the first insert 210 matches the outer contour of the outer surface of the injection molding edge 230 away from the second insert 220. In this way, the outer surface of the injection molding edge 230 will not shrink or deform extremely slightly during the cooling molding process after the injection molding is completed, so that the injection molding edge 230 with uniform and moderate thickness can be molded on the outer side of the second insert 220, avoiding shrinkage deformation of the outer surface during the molding process of the injection molding edge 230, thereby ensuring the appearance quality.

[0066] The connection between the injection molding edging 230 and the glass 100 may be achieved by snapping or the like. For example, a snap hook 2111 that snaps with the edge of the glass 100 may be provided at a suitable position of the injection molding edging 230 .

[0067] In order to avoid shrinkage marks on the surface of the injection molding edging 230, the traditional method is to fill an integral insert between the injection molding edging 230 and the glass 100. The integral insert is relatively thick, which causes shrinkage deformation of the outer surface during molding. The shrinkage deformation of the integral insert is transmitted to the injection molding edging 230, resulting in shrinkage deformation of the outer surface during the molding process of the injection molding edging 230. The edging structure 200 of the above embodiment of the present application supports the injection molding edging 230 by arranging a first insert 210 and a second insert 220 between the injection molding edging 230 and the glass 100, and using the structure formed by the connection of the first insert 210 and the second insert 220 to support the injection molding edging 230. In addition, the second insert 220 is arranged closer to the injection molding edging 230 relative to the first insert 210, and the thickness of the second insert 220 is set to a preset thickness. Compared with the traditional integral insert, the thickness of the second insert 220 is thinner, so that the outer surface of the second insert 220 will not shrink or deform extremely slightly during the molding process, thereby ensuring that the injection molding edging 230 covering the outer side of the second insert 220 has a uniform and moderate thickness during the molding process, so that the outer surface of the injection molding edging 230 will not shrink during the molding process, thereby ensuring the appearance quality.

[0068] Optionally, the second insert 220 is configured to have a uniform thickness. With this arrangement, the contour shape of the outer surface of the second insert 220 facing away from the first insert 210 is uniform and will not shrink or deform. In addition, the outer surface of the second insert 220 facing away from the first insert 210 and the outer surface of the injection molding edging 230 facing away from the second insert 220 are contoured to each other, thereby ensuring that the injection molding edging 230 also has a thickness, so that the outer surface of the injection molding edging 230 will not shrink or deform during the molding process, thereby ensuring the appearance quality.

[0069] In addition, the second insert 220 has a preset thickness and a uniform thickness, so that the outer surface of the second insert 220 will not shrink or deform during a single molding process. In addition, the outer surface of the second insert 220 that is away from the first insert 210 is configured to be contoured with the outer surface of the second insert 220 that is away from the injection molding edge 230, so that the thickness of the injection molding edge 230 is uniform during molding, and shrinkage and deformation of the outer surface of the injection molding edge 230 can be avoided during molding, thereby ensuring the appearance quality.

[0070] like Figure 3 As shown, in addition, the first insert 210 further has a first assembly surface 213 facing away from the connection surface 212, and the second insert 220 further has a second assembly surface 222 facing the first insert 210. Moreover, when the second connection portion 221 is connected to the first connection portion 211, that is, when the first insert 210 and the second insert 220 are assembled and connected, the second assembly surface 222 and the first assembly surface 213 are relatively spaced apart by a preset gap. With such a configuration, there is a gap between the first assembly surface 213 and the second assembly surface 222. The gap can not only offset or compensate for the thickness error of the first insert 210 and the second insert 220 during the separate molding process, but also the gap exists as a preset gap, so that there is less air between the first assembly surface 213 and the second assembly surface 222. During the injection molding of the injection molding edge 230, only a small amount of injection plastic flows into the gap, which can avoid the collapse and deformation of the second insert 220 caused by squeezing due to trapped air, thereby avoiding the collapse and deformation of the second insert 220 being transmitted to the injection molding edge 230 to cause the collapse and deformation of the injection molding edge 230, ensuring that the thickness of the injection molding edge 230 is uniform and moderate, so that the outer surface of the injection molding edge 230 will not shrink and deform during the molding process, thereby ensuring the appearance quality.

[0071] Specifically, the preset gap is L (such as Figure 3 ), and 0mm<L≤0.5mm (L can be 0.1mm, 0.2mm, 0.3mm, 0.4mm or 0.5mm). In this way, the preset gap has a moderate spacing, which can effectively offset or compensate for the thickness error of the first insert 210 and the second insert 220 during the separate molding process, and can also effectively avoid the collapse and deformation caused by squeezing the second insert 220 due to trapped air.

[0072] Preferably, 0.05mm≤L≤0.5mm (L can be 0.05mm, 0.15mm, 0.25mm, 0.35mm, 0.45mm or 0.5mm). In this way, there is less air between the first assembly surface 213 and the second assembly surface 222. When a small amount of injection plastic flows into the space between the first assembly surface 213 and the second assembly surface 222, it can better prevent the collapse and deformation of the second insert 220 from being transmitted to the injection molding edge 230 to cause the collapse and deformation of the injection molding edge 230, thereby ensuring that the thickness of the injection molding edge 230 is uniform and moderate, so that the outer surface of the injection molding edge 230 will not shrink and deform during the molding process, thereby ensuring the appearance quality; at the same time, the gap between the first assembly surface 213 and the second assembly surface 222 can also be used to offset or compensate for the thickness error of the first insert 210 and the second insert 220 during the separate molding process.

[0073] Furthermore, the edging structure 200 further includes a first adhesive layer (not shown) such as an adhesive tape or adhesive. Thus, the first assembly surface 213 and the second assembly surface 222 are bonded by the bonding effect of the first adhesive layer, and then the first insert 210 and the second insert 220 are bonded, so that the first insert 210 and the second insert 220 are stably and reliably connected and fixed. The first adhesive layer is combined with the connection between the first connecting portion 211 and the second connecting portion 221, so that the connection and fixation between the first insert 210 and the second insert 220 is more stable and reliable.

[0074] In addition, the number of first inserts 210 can be flexibly designed or adjusted according to actual edging needs. For example, there can be at least two first inserts 210, and at least two first inserts 210 overlap each other, so as to support the injection molding edging 230 together with the second insert 220.

[0075] In addition, the number of the second inserts 220 can be flexibly designed or adjusted according to the actual edge binding needs. For example, there can be at least two second inserts 220, and at least two second inserts 220 overlap each other, so as to support the injection molding edge 230 together with the first insert 210. In addition, each second insert 220 has a preset thickness, so that each second insert 220 will not shrink or deform, thereby ensuring that the injection molding edge 230 wrapped around the outside of the second insert 220 will not shrink or deform.

[0076] In one embodiment, a hemming method is also provided, comprising the following steps:

[0077] S100, obtaining a first insert 210 by an integrated molding method, and connecting the first insert 210 with the glass 100 with its connecting surface 212 facing the glass 100;

[0078] S200, obtaining a second insert 220 having a preset thickness by an integrated molding method, so that the second insert 220 is covered on the outside of the first insert 210, and the second connecting portion 221 of the second insert 220 is connected to the first connecting portion 211 of the first insert 210;

[0079] S300 , injection molding is performed on the outer side of the second insert 220 to obtain an injection molding edge 230 , so that the injection molding edge 230 covers the outer side of the second insert 220 and is connected to the glass 100 to encapsulate the first insert 210 and the second insert 220 .

[0080] The edging method of the above embodiment is to support the injection molding edging 230 by arranging the first insert 210 and the second insert 220 between the injection molding edging 230 and the glass 100, and using the structure formed by the connection between the first insert 210 and the second insert 220. In addition, the second insert 220 is arranged closer to the injection molding edging 230 than the first insert 210, and the thickness of the second insert 220 is set to a preset thickness. Compared with the traditional integral insert, the thickness of the second insert 220 is thinner, so that the outer surface of the second insert 220 will not shrink or shrink very slightly during the molding process, thereby ensuring that the injection molding edging 230 wrapped on the outer side of the second insert 220 has a uniform and moderate thickness during the molding process, so that the outer surface of the injection molding edging 230 will not shrink during the molding process, and the appearance quality is guaranteed.

[0081] It should be noted that the integral molding of the first insert 210 and the integral molding of the second insert 220 may be processed in any order and are preferably performed simultaneously to save processing time.

[0082] It should be noted that "some body" or "some part" can be a part of the corresponding "component", that is, "some body" or "some part" can be integrally formed with the "other parts of the component"; it can also be an independent component that can be separated from the "other parts of the component", that is, "some body" or "some part" can be manufactured independently and then combined with the "other parts of the component" into a whole. The expression of the above-mentioned "some body" or "some part" in this application is only one of the embodiments, for the convenience of reading, and not to limit the scope of protection of this application. As long as it contains the above-mentioned features and has the same function, it should be understood as an equivalent technical solution of this application.

[0083] It should be noted that the components included in the "unit", "assembly", "mechanism" and "device" of this application can also be flexibly combined, that is, modular production can be carried out according to actual needs to facilitate modular assembly. The division of the above components in this application is only one of the embodiments, for the convenience of reading, and not to limit the scope of protection of this application. As long as the above components are included and have the same functions, it should be understood that it is an equivalent technical solution of this application.

[0084] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. The term "and / or" used in the present invention includes any and all combinations of one or more related listed items.

[0085] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0086] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0087] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0088] It should be noted that when an element is referred to as being "fixed on", "set on", "fixed on" or "installed on" another element, it can be directly on the other element or there can be a central element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there can be a central element at the same time. Further, when an element is considered to be "fixed transmission connected" to another element, the two can be fixed in a detachable connection manner or in a non-detachable connection, as long as power transmission can be achieved, such as socketing, snap-on, one-piece molding fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0089] It should also be understood that when explaining the connection relationship or positional relationship of elements, although not explicitly described, the connection relationship and positional relationship are interpreted as including an error range, which should be within the acceptable deviation range of a specific value determined by those skilled in the art. For example, "approximately", "approximately" or "substantially" may mean within one or more standard deviations, which are not limited here.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0091] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
