Technical Field

[0001] This utility model belongs to the field of automobile manufacturing technology, specifically relating to a laminated glass edging structure and a vehicle window glass assembly. Background Technology

[0002] Some high-end models employ a design where the side windows are flush with the same curved surface to achieve a better visual appearance and a lower drag coefficient, thereby reducing energy consumption and increasing driving range. Furthermore, to improve safety, sound insulation, and heat insulation, an increasing number of models are using double-layered laminated glass instead of single-layered glass. Meanwhile, to ensure the overall flatness of the vehicle's sides and to provide sound insulation, waterproofing, and dustproofing, a sealing strip is typically installed between the side window glass and the exterior window trim. However, existing sealing strips have a small contact area with the side window glass and exterior window trim, resulting in poor sealing performance. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies, this utility model provides a laminated glass edging structure and a vehicle window glass assembly, aiming to solve the technical problem that the existing sealing strip has poor sealing performance due to the small contact area with the side window glass and the exterior trim panel of the vehicle window.

[0004] To achieve the above objectives, the first aspect of this utility model provides a laminated glass edging structure, wherein the laminated glass edging structure includes laminated glass and an edging; the laminated glass has an outer glass sheet, an interlayer, and an inner glass sheet stacked sequentially, the inner glass sheet extending beyond the outer glass sheet on the sealing side; the edging covers the edge of the sealing side of the inner glass sheet, the edging includes an outer edging section covering the outer side of the inner glass sheet, the outer surface of the outer edging section being lower than the outer surface of the outer glass sheet to form an outwardly facing stepped space, the outer edging section extending to cover the interlayer.

[0005] In one embodiment of the present invention, the edging further includes an end-side edging section and an inner-side edging section. The end-side edging section covers the end side of the inner glass sheet, and the inner-side edging section covers the inner side of the inner glass sheet. The thickness of the inner-side edging section is greater than the thickness of the outer-side edging section.

[0006] In one embodiment of the present invention, the outer glass sheet has a first rounded chamfer at a first corner position near the inner glass sheet, and the edge extending to the end covering the laminated layer has a first arc-shaped concave surface. The first arc-shaped concave surface is located on the outside of the laminated layer and can be sealed and fitted with the first rounded chamfer.

[0007] In one embodiment of the present invention, the outer glass sheet has a second rounded chamfer surface at a second corner position away from the inner glass sheet, and the outer sealing strip on the outer edge section has a second arc-shaped concave surface that can seal and fit with the second rounded chamfer surface.

[0008] To achieve the above objectives, the second aspect of this utility model provides a vehicle window glass assembly, including the aforementioned laminated glass edging structure and an outer trim panel, wherein the outer trim panel extends into the stepped space, the outer side of the outer trim panel is flush with the outer glass sheet, and the inner side of the outer trim panel is tightly connected to the outer edging section.

[0009] In one embodiment of this utility model, an outer sealing strip is provided between the outer trim panel and the outer edge banding section.

[0010] In one embodiment of the present invention, the vehicle window assembly further includes a window sheet metal, and the edging includes an inner edging section, the inner side of which is sealed and fitted to the window sheet metal by an inner sealing strip.

[0011] In one embodiment of this utility model, the inner sealing strip is a hollow sealing strip.

[0012] In one embodiment of this utility model, the vehicle window glass assembly further includes a sound-absorbing cloth, which is disposed on the side of the outer sealing strip near the outer edge section.

[0013] In one embodiment of this utility model, the outer sealing strip is a solid sealing strip.

[0014] In one embodiment of the present invention, the laminated glass includes a front door laminated glass and a rear door laminated glass, and an outer trim panel is disposed between the front door laminated glass and the rear door laminated glass, with the front and rear ends of the outer trim panel extending into the step space of the front door laminated glass and the rear door laminated glass, respectively.

[0015] Through the above technical solution, the laminated glass edge-wrapping structure provided by this utility model embodiment has the following beneficial effects: This laminated glass edging structure features an inner glass pane that extends beyond the outer glass pane on the sealing side. The edging covers the portion of the inner glass pane that extends beyond the outer glass pane, with the outer surface of the outer edging section lower than the outer surface of the outer glass pane, forming a recessed, outward-facing stepped space. When installed on a vehicle window, the exterior trim panel extends into the stepped space and fits snugly against the outer edging section, making the exterior trim panel flush with the outer surface of the laminated glass. This reduces wind resistance during vehicle movement and increases the contact area with the exterior trim panel, thereby improving sealing performance. Furthermore, the stepped fit between the edging structure and the exterior trim panel provides high strength, making the window assembly more stable and providing a tighter seal between the window and the exterior trim panel when the vehicle sways laterally or encounters strong crosswinds, preventing shaking and abnormal noises.

[0018] Explanation of reference numerals in the attached figures: Detailed Implementation

[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] The following description, with reference to the accompanying drawings, describes the laminated glass edging structure and vehicle window assembly of this utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a laminated glass edge-wrapping structure, comprising: Laminated glass has an outer glass sheet 110, an interlayer 140 and an inner glass sheet 120 stacked sequentially, with the inner glass sheet 120 extending out of the outer glass sheet 110 on the sealing side. Edge 130 covers the edge of the sealing side of the inner glass sheet 120. Edge 130 includes an outer edge section 131 covering the outer side of the inner glass sheet 120. The outer surface of the outer edge section 131 is lower than the outer surface of the outer glass sheet 110 to form an outwardly arranged stepped space. The outer edge section 131 extends to cover the interlayer 140.

[0022] When the above-mentioned laminated glass edging structure is used, since the inner glass sheet 120 of the laminated glass extends beyond the outer glass sheet 110 on the sealing side, the edging 130 covers the part of the inner glass sheet 120 that extends beyond the outer glass sheet 110, forming an outwardly facing stepped space on the outer surface of the outer edging section 131. The outer trim panel 200 extends into the stepped space and is sealed and fitted to the outer edging section 131. Through the above structure, on the one hand, the outer trim panel 200 is flush with the outer surface of the laminated glass, reducing wind resistance when the car is driving. On the other hand, the contact area between the edging 130 and the outer trim panel 200 can be increased to improve the sealing performance. Furthermore, the stepped fit between the edging 130 and the outer trim panel 200 results in high fit strength. When the vehicle sways laterally or encounters strong crosswinds, the window assembly is more stable, and the seal between it and the outer trim panel 200 is tighter, avoiding shaking and abnormal noise. It should be noted that the laminated glass mentioned in this utility model can be at least one of the front door laminated glass 100a, the rear door laminated glass 100b, and the rear corner window module. The inner glass pane 120 faces inwards from the vehicle, and the outer glass pane 110 faces outwards from the vehicle.

[0023] Specifically, the edging 130 can be made of an elastic material such as rubber, specifically TPV (Thermoplastic Vulcanizate), and the edging 130 is integrally molded and wrapped around the laminated glass. The interlayer 140 is flush with the outer glass sheet 110, the sealing side of the edging 130 is lower than the outer glass sheet 110, and the side of the edging 130 away from the sealing side is joined with the inner glass sheet 120, the interlayer 140, and a portion of the outer glass sheet 110. The edging 130 extends to cover the interlayer 140 between the inner glass sheet 120 and the outer glass sheet 110 to seal and encapsulate the interlayer 140, thereby preventing cracking, bubbles, and other problems from occurring in the interlayer 140. At the same time, the edging 130 can also prevent the interlayer 140 from being physically damaged, thus protecting the interlayer 140.

[0024] In one embodiment of this utility model, the edge banding 130 includes an outer edge banding section 131, an end edge banding section 132, and an inner edge banding section 133 arranged sequentially. The outer edge banding section 131 covers the outer side of the inner glass sheet 120 and extends to cover the laminated adhesive 140. The outer edge banding section 131 can be sealed and fitted with the sealing side 320 of the inner sheet. The end edge banding section 132 covers the end side of the inner glass sheet 120, and the inner edge banding section 133 covers the inner side of the inner glass sheet 120. That is, the edge banding 130 is arranged in a U-shape to fully wrap the end edge of the inner glass sheet 120. This structure can improve the reliability of the edge banding 130 on the laminated glass. Meanwhile, the thickness of the inner edge section 133 is set to be greater than that of the outer edge section 131, which can improve the reliability of the edge 130 on the laminated glass. When the edge structure is fitted with the outer trim panel 200, it can also leave more space for the outer sealing strip 300 between the edge structure and the outer trim panel 200, thereby reducing the thickness of the door.

[0025] See Figures 1 to 3 In one embodiment of this utility model, the outer glass sheet 110 has a first rounded chamfer surface 111 at a first corner position near the inner glass sheet 120. The edge 130 extends to one end covering the laminated layer 140 and has a first arc-shaped concave surface 134. The first arc-shaped concave surface 134 is located on the outside of the laminated layer 140 and can seal and fit with the first rounded chamfer surface 111. That is, the first arc-shaped concave surface 134 and the first rounded chamfer surface 111 form an arc-shaped sealing structure. By providing an arc-shaped sealing structure on the outside of the laminated layer 140, external moisture can be effectively prevented from entering the laminated layer 140.

[0026] See Figure 1 , Figure 2 and Figure 4 In one embodiment of this utility model, the outer glass sheet 110 has a second rounded chamfer surface 112 at a second corner position away from the inner glass sheet 120, and the outer sealing strip 300 has a second arc-shaped concave surface 330 that can seal and fit with the second rounded chamfer surface 112. That is, the second arc-shaped concave surface 330 and the second rounded chamfer surface 112 also form an arc-shaped sealing structure, which improves the sealing performance between the outer sealing strip 300 and the outer glass sheet 110. Furthermore, when applied to the rear door laminated glass 100b, when the rear door of the car is opened, the second rounded chamfer surface 112 on the outer glass sheet 110 can maintain a seal and fit with the second arc-shaped concave surface 330. Specifically, as shown... Figure 7 As shown.

[0027] Furthermore, this utility model also provides a vehicle window assembly, including the aforementioned laminated glass edging structure and an outer trim panel 200. The outer trim panel 200 extends into the stepped space of the edging 130, the outer side of the outer trim panel 200 is flush with the outer glass sheet 110, and the inner side of the outer trim panel 200 is tightly connected to the edging 130. Since the vehicle window assembly adopts all the technical solutions of the aforementioned laminated glass edging structure embodiment, it possesses at least all the beneficial effects brought about by the technical solutions of the aforementioned embodiments.

[0028] Furthermore, an outer sealing strip 300 is provided between the outer trim panel 200 and the outer edging section 131. The outer sealing strip 300 fits tightly with the edging 130 and includes an outer sealing side 310 and an inner sealing side 320. The outer sealing side 310 is located between the end side of the outer trim panel 200 and the end side of the outer glass sheet 110 and can seal and fit with the outer trim panel 200 and the outer glass sheet 110. The inner sealing side 320 is located between the inner side of the outer trim panel 200 and the outer surface of the outer edging section 131 and can seal and fit with the outer trim panel 200 and the outer edging section 131. Thus, the sealing area includes the contact area with the front or rear end of the outer trim panel 200, the contact area with the inner side of the outer trim panel 200, the contact area with the end side of the outer glass sheet 110, and the contact area with the edging 130, resulting in better sealing performance.

[0029] See Figure 1 In one embodiment of this utility model, the vehicle window assembly further includes a window sheet 400, on which an inner sealing strip 500 is provided, capable of sealingly fitting with the edging 130. Specifically, the window sheet 400 is located on the inner side of the exterior trim panel 200, and the inner sealing strip 500 is designed to sealably fit with the inner edging section 133 of the edging 130. The addition of the inner sealing strip 500 prevents external dust, moisture, etc., from entering the vehicle interior. Of course, this utility model is not limited to this; the edging 130 can also be designed to directly contact the window sheet 400.

[0030] In one embodiment of this utility model, the inner sealing strip 500 is a hollow sealing strip, which allows for greater deformation, thereby ensuring the smooth opening and closing of the vehicle door. Specifically, the hollow sealing strip is annular in its free state, that is, it is annular before being compressed and deformed.

[0031] In one embodiment of this utility model, the outer sealing strip 300 is a solid sealing strip, which can make the interference fit between the outer sealing strip 300 and the edge 130 and between the outer sealing strip 300 and the outer trim panel 200 strong. When the car sways laterally or encounters strong crosswinds, the outer trim panel 200 with the outer sealing strip 300 can support the laminated glass, thereby reducing the occurrence of shaking and abnormal noise.

[0032] In one embodiment of this utility model, both the outer sealing strip 300 and the inner sealing strip 500 can be made of EPDM (Ethylene Propylene Diene Monomer) sealing strips. Of course, this utility model is not limited to this, and sealing strips made of other suitable rubber materials are also possible.

[0033] See Figure 1 and Figure 4 In one embodiment of this utility model, the vehicle window glass assembly further includes a sound-absorbing cloth 600, which is disposed on the side of the outer sealing strip 300 near the outer edge section 131. The addition of the sound-absorbing cloth 600 reduces noise caused by friction between the edge section 130 and the outer sealing strip 300 during the raising and lowering of the laminated glass. Specifically, the inner sealing side 320 is provided with a groove that matches the shape of the sound-absorbing cloth 600, and the sound-absorbing cloth 600 is fixed within the groove to improve the assembly precision of the sealing structure.

[0034] See Figure 5 In one embodiment of this utility model, the laminated glass includes a front door laminated glass 100a and a rear door laminated glass 100b. Both the front door laminated glass 100a and the rear door laminated glass 100b have an outer glass sheet 110, an inner glass sheet 120, and an adhesive layer 140. The exterior trim panel 200 is set as the B-pillar trim located between the front door laminated glass 100a and the rear door laminated glass 100b. The front and rear ends of the B-pillar trim extend into the stepped spaces of the front door laminated glass 100a and the rear door laminated glass 100b respectively, and both the front and rear ends of the B-pillar trim are provided with outer sealing strips 300. That is, both the front door laminated glass 100a and the rear door laminated glass 100b of the automobile use the above-described laminated glass to improve the overall window sealing performance of the vehicle. It should be noted that the B-pillar exterior trim is connected to the front door of the car. Therefore, the outer sealing strip 300 corresponding to the front door laminated glass 100a is connected to both the B-pillar exterior trim and the front door laminated glass 100a. However, the outer sealing strip 300 corresponding to the rear door laminated glass 100b is only connected to the B-pillar exterior trim assembly. The window sheet metal 400 has a front window sheet metal part 410 and a rear window sheet metal part 420 that correspond one-to-one with the front door laminated glass 100a and the rear door laminated glass 100b, respectively.

[0035] Specifically, such as Figure 5The front and rear doors of the car shown are both closed. At this time, the inner sealing strip 500 corresponding to the front door laminated glass 100a is compressed, while the inner sealing strip 500 corresponding to the rear door laminated glass 100b is free. Simultaneously, the outer surfaces of the B-pillar trim, the outer surfaces of the outer sealing strips 300 of the front and rear door laminated glass 100a and 100b, the outer surfaces of the glass outer sheet 110 of the front and rear door laminated glass 100a, and the outer surfaces of the glass outer sheet 110 of the rear door laminated glass 100b are flush, thus achieving a flush side profile for the car. Figure 6 The car shown has its front door open and rear door closed. At this time, the inner sealing strips 500 of both the front door laminated glass 100a and the rear door laminated glass 100b are in a free state. Figure 7 The front door of the car shown is closed and the rear door is open. At this time, the inner sealing strips 500 of the front door laminated glass 100a and the rear door laminated glass 100b are in a compressed state.
