Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and particularly to laminated glass with a transition structure, a vehicle door, and a vehicle. Background Art

[0002] In the field of vehicles, laminated glass is favored by consumers due to its good sound insulation effect and firmness, and is widely used. For example, frameless vehicle doors are generally equipped with laminated glass. The laminated glass includes an inner glass sheet, an intermediate bonding layer, and an outer glass sheet. The intermediate bonding layer is located between the inner glass sheet and the outer glass sheet. The inner glass sheet is thinner than the outer glass sheet. When the inner glass sheet is thermoformed on a hot bending roller path, waves are likely to occur at the edges. The inner glass sheet with wavy edges will be forced to bend to fit the outer glass sheet during lamination, and at the same time, the inner glass sheet will also pull the outer glass sheet. The wavy edges will result in a large gap between the inner glass sheet and the outer glass sheet before lamination, and there are also differences in the gap sizes at different positions. As a result, the flow thickness of the intermediate layer between the two glass sheets is uneven at various positions, and the finally formed laminated glass will have the problem of light distortion. Summary of the Invention

[0003] In view of the problem of light distortion in laminated glass caused by the wavy edges of the inner glass sheet, the present invention provides a laminated glass with a transition structure, a vehicle door, and a vehicle. By adding an auxiliary transition plate, the lower edge line of the inner glass sheet can be designed as a straight line, thereby avoiding the occurrence of waves at the edges during the processing of the inner glass sheet, and ensuring that the laminated glass will not have the phenomenon of light distortion after lamination.

[0009] In one embodiment, the thickness of the auxiliary transition plate gradually increases in the direction close to the inner glass sheet, and the thickness of the auxiliary transition plate at the position aligned with the inner glass sheet is the same as the sum of the thicknesses of the inner glass sheet and the intermediate bonding layer.

[0032] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be made in conjunction with the accompanying drawings. Many specific details are set forth in the following description to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0033] Generally, in addition to the laminated glass 10, a vehicle door also includes a lifting mechanism for driving the laminated glass 10 to move up and down, as well as some other components hidden in the door sheet metal. Generally, the laminated glass 10 is provided with acting holes 122 for the lifting mechanism to clamp. In some cases, the acting holes 122 are formed on the outer sheet glass 12. When the laminated glass 10 moves up and down, it needs to provide a clearance space for these components in the door to avoid interference between the laminated glass 10 and these components. Especially when the laminated glass 10 descends to the lowest position, almost all of the laminated glass 10 is located in the space surrounded by the door sheet metal. At this time, the lower edge of the laminated glass 10 is at the lowest position it can reach. A clearance notch is provided at the lower edge of the laminated glass 10 so that the laminated glass 10 will not interfere with other components when in the aforementioned lowest position. In some cases, the clearance notch is in a rounded corner shape.

[0034] To ensure the sealing performance of the vehicle door, water dams are provided on both the inner and outer sides of the laminated glass 10 in the vehicle door. The water dam on the outer side of the laminated glass 10 is the outer water dam, and the water dam on the inner side of the laminated glass 10 is the inner water dam. Generally, the acting position of the outer water dam on the laminated glass 10 is higher than that of the inner water dam on the laminated glass 10, so that the laminated glass 10 has a tendency to pre-bend towards the interior of the vehicle, and then the laminated glass 10 can be in close contact with the sealing strip around the vehicle frame. Therefore, the inner sheet glass 11 of the traditional laminated glass 10 needs to extend downward as much as possible to abut and seal with the inner water dam, and the aforementioned clearance notch is provided at the part that needs to extend downward here. So the lower edge of the inner sheet glass 11 is uneven. As Figure 7 shown, waves are likely to appear at the uneven position of the inner sheet glass 11 during hot bending, which will lead to the problem of light distortion in the finally laminated glass 10 formed by laminating. As Figure 7 shown in the lower edge of the traditional inner sheet glass 11, the larger the protruding area, the greater the undulation of the wavy edge. For example, as Figure 7 shown, the part of the inner sheet glass 11 on the right side of the clearance notch has a larger protruding area, and the undulation of the wavy edge on the right side is larger after rolling.

[0035] Therefore, in some embodiments of the present application, a laminated glass 10 with a transition structure is proposed. As Figure 1 shown, it not only includes an outer sheet glass 12, an inner sheet glass 11 and an intermediate bonding layer 13, but also includes an auxiliary transition plate 14. The inner sheet glass 11 is located inside the outer sheet glass 12, and the intermediate bonding layer 13 is connected between the outer sheet glass 12 and the inner sheet glass 11. The lower edge line 111 of the inner sheet glass 11 is a straight line, and the lower edge line 111 is retracted relative to the lower edge of the outer sheet glass 12. As Figure 3 and Figure 4As shown, the auxiliary transition plate 14 is provided on the inner side surface of the outer sheet glass 12, and the upper edge line of the auxiliary transition plate 14 is aligned with the lower edge line 111 of the inner sheet glass 11. By adding the auxiliary transition plate 14 below the inner sheet glass 11, the lower edge line of the inner sheet glass 11 can be designed as a straight line, thereby avoiding the situation of waves appearing at the edge during the processing of the inner sheet glass 11, and further ensuring that the laminated glass 10 does not have the phenomenon of optical distortion after lamination.

[0036] Furthermore, as Figure 2 , Figure 3 and Figure 5 shown, in some embodiments, a first relief notch 121 is provided at the lower edge of the outer sheet glass 12. A second relief notch 141 is provided at a position corresponding to the first relief notch 121 on the lower edge of the auxiliary transition plate 14. As Figures 1 to 3 shown, in certain embodiments, the edge line of the second relief notch 141 is parallel to the edge line of the first relief notch 121, and the edge line of the second relief notch 141 is set to be retracted relative to the edge line of the first relief notch 121, and the edge line of the second relief notch 141 is shorter than the edge line of the first relief notch 121.

[0037] The first relief notch 121 and the second relief notch 141 form a relief notch of the laminated glass 10, and a relief space is provided for components when the laminated glass 10 is lifted and lowered.

[0038] The second relief notch 141 for providing relief for components is formed on the auxiliary transition plate 14. The lower edge line 111 of the inner sheet glass 11 only needs to be mainly considered in cooperation with the auxiliary transition plate 14, so the lower edge line of the inner sheet glass 11 can be designed as a straight line. When the laminated glass 10 is lifted and lowered, the lip of the inner water cut slides on the auxiliary transition plate 14 and the inner sheet glass 11, so that a good abutting and sealing state can be maintained between the inner water cut and the laminated glass 10 during this process. Generally speaking, the optimized laminated glass 10 of the present application can not only meet the requirements of abutting and sealing with the inner water cut, but also avoid the situation of waves appearing at the edge during the processing of the inner sheet glass 11, ensuring the optical performance of the laminated glass 10 after lamination.

[0039] The inner sheet glass 11 is thinner than the outer sheet glass 12, and generally, a hot bending roller path is used for extrusion and shaping during hot bending forming. As Figure 7As shown, when the inner glass sheet 11 enters the hot bending track, it is in a softened state. Under the action of gravity, the inner glass sheet 11 will sag to some extent. When the roller 20 of the hot bending roller path presses the inner glass sheet 11, the part that originally had a tendency to sag will be bent upward. If the lower edge of the inner glass sheet 11 is uneven, then each part of the lower edge line 111 will come into contact with the roller 20 at different times and be pressed and bent upward by the roller 20, eventually forming a wavy edge. Here, the wavy edge refers to the fact that the lower edge line 111 has a wavy undulation in the thickness direction of the inner glass sheet 11.

[0040] In the laminated glass 10 proposed in this application, the lower edge line 111 of the inner glass sheet 11 is designed as a straight line. During hot bending forming, the lower edge line 111 is parallel to the axial direction of the roller 20, thereby avoiding the formation of a wavy edge. Moreover, the straight lower edge line 111 of the inner glass sheet 11 can also reduce the probability of edge breakage of the inner glass sheet 11 during pre-treatment. Specifically, the straight lower edge line 111 has fewer corners compared to the uneven lower edge line 111, so the probability of edge breakage during pre-treatment processes such as cutting, breaking, and grinding is greatly reduced.

[0041] As Figure 7 shown, the traditional inner glass sheet 11 has a relief notch at the lower edge, and the lower edge line 111 has 7 corners. And as Figure 3 shown, when the lower edge line 111 of the inner glass sheet 11 in this application is a straight line, the lower edge line 111 only has 2 corners. The number of corners is greatly reduced.

[0042] As Figure 1 and Figure 3 shown, the upper edge line of the auxiliary transition plate 14 is a straight line. The auxiliary transition plate 14 can be processed by injection molding or other methods, and there is no need to be processed on the hot bending roller path like the inner glass sheet 11. Therefore, designing the second relief notch 141 on the auxiliary transition plate 14 will not have the problem of forming a wavy edge during processing.

[0043] In some embodiments, there is no gap between the auxiliary transition plate 14 and the lower edge line 111 of the inner glass sheet 11, and the inner water cut can smoothly transition between the two.

[0044] Furthermore, as Figure 5 and Figure 6 shown, in some embodiments, the thickness of the auxiliary transition plate 14 gradually increases in the direction close to the inner glass sheet 11, so that the inner water cut has a process of gradual transition during sliding, rather than directly transitioning from the state of contacting the outer glass sheet 12 to the state of contacting the inner glass sheet 11.

[0045] The surface of the auxiliary transition plate 14 facing away from the inner sheet glass 12 is an inclined surface with a certain slope, and this inclined surface can play a role in transition and guidance. The auxiliary transition plate 14 is shaped like a wedge block, so that the lip of the inner water cut will not curl in the reverse direction when the laminated glass 10 is lifted or lowered.

[0046] Further specifically, as Figure 5 and Figure 6 shown, the thickness of the auxiliary transition plate 14 at the position aligned with the inner sheet glass 12 is the same as the sum of the thicknesses of the inner sheet glass 11 and the intermediate connection layer 13. After the inner water cut transitions to contact with the auxiliary transition plate 14, it can smoothly transition to the state of contacting the inner sheet glass 11.

[0047] In some embodiments, the inner water cut has an upper lip and a lower lip. The upper lip and the lower lip are parallel and arranged at intervals, and the upper lip is located above the lower lip. When the laminated glass 10 rises to the highest position, the upper lip abuts against the inner sheet glass 11, and the lower lip abuts against the auxiliary transition plate 14. When the laminated glass 10 is lifted or lowered, the lower lip needs to slide from the auxiliary transition plate 14 onto the inner sheet glass 11. The inclined surface design of the auxiliary transition plate 14 can ensure that the lower lip will not curl in the reverse direction during this process.

[0048] Further, in some embodiments, when the laminated glass 10 rises to the highest position, the position on the inner sheet glass 11 for abutting against the upper lip of the inner water cut is the first water cut line (not marked in the figure). The distance between the lower edge line 111 of the inner sheet glass 11 and the first water cut line is not less than 10 mm, ensuring that there is enough position on the inner sheet glass 11 for the upper lip of the inner water cut to abut during installation.

[0049] In some other embodiments, when the laminated glass 10 rises to the highest position, the position on the auxiliary transition plate 14 for abutting against the lower lip of the inner water cut is the second water cut line (not marked in the figure). The maximum distance between the lower edge line of the auxiliary transition plate 14 and the second water cut line is not less than 15 mm, ensuring that there is enough position on the auxiliary transition plate 14 for the upper lip of the inner water cut to abut during installation.

[0050] It should be noted that when the laminated glass 10 rises to the highest position, perhaps the entire lower lip of the inner water cut does not contact the auxiliary transition plate 14, that is, the two do not fit 100%. There is a situation where the height of the lower lip matches the position of the second relief notch 141 on the auxiliary transition plate 14. A part of the lower lip contacts the auxiliary transition plate 14, and another part is opposite to the second relief notch 141. Of course, in order to increase the proportion of the lower lip that can contact the auxiliary transition plate 14 as much as possible, the lower edge line 111 of the auxiliary transition plate 14 can be extended downward as much as possible, and as described above, the maximum distance between the lower edge line 111 and the second water cut line can be made larger.

[0051] Further, as Figures 4 to 6 shown, in one embodiment, the corner of the lower edge of the auxiliary transition plate 14 is an arc chamfer 142 to avoid the sharp edge from scratching the sealing strip. When the laminated glass 10 rises to the highest position, the lower lip of the inner water cut may be partially opposite to the second relief notch 141. Therefore, this section of the sealing structure of the lower lip will change from the state of contacting the outer glass 12 to the state of contacting the auxiliary transition plate 14, and the lower lip will scrape against the lower edge line of the auxiliary transition plate 14. The design of the above arc chamfer 142 can ensure that the lower lip can smoothly change from the state of contacting the outer glass 12 to the state of contacting the auxiliary transition plate 14, and there will be no scratching during this process, and there will be no reverse curling situation.

[0052] The corner of the lower edge of the outer glass 12 can also be designed as an arc chamfer to further reduce the risk of the inner water cut lip being scratched. The chamfer radius of the arc chamfer 142 on the auxiliary transition plate 14 and the chamfer radius of the arc chamfer on the outer glass 12 can be different.

[0053] In some embodiments, as Figures 3 to 6 shown, the auxiliary transition plate 14 is bonded to the outer glass 12, and the connection is tight and reliable. Specifically, a structural tape can be used, which has strong adhesion, is not easy to fall off, and is corrosion-resistant. Compared with the thickness of the auxiliary transition plate 14, the thickness of the adhesive used to bond the auxiliary transition plate 14 and the outer glass 12 can be ignored.

[0054] Optionally, in other embodiments, other connection methods can also be used between the auxiliary transition plate 14 and the outer glass 12, and no specific limitation is made here.

[0055] In some embodiments, the auxiliary transition plate 14 is adhered to the inner side surface of the outer glass 12 by an adhesive such as PU glue (chemical name: polyurethane resin), PVB (also known as: polyvinyl butyral), or tape.

[0056] Further, in some embodiments, the auxiliary transition plate 14 is an injection molded part, which is convenient for processing and molding, and there will be no problem of wavy edges due to the existence of the second relief notch 141.

[0057] In some embodiments, when the auxiliary transition plate 14 is an injection molded part, a sealant can be used to fill the possible gap between the auxiliary transition plate 14 and the lower edge line 111 of the inner glass 11 to prevent problems such as abnormal noise during the sliding of the water cut and hindrance to lifting due to the gap.

[0058] In some embodiments, the auxiliary transition plate 14 is made of a colloid. In a preferred embodiment, the colloid is made of a self-lubricating material, so that the auxiliary transition plate 14 has a self-lubricating function and the stiffness meets the use requirements, and the lower lip of the inner water cut slides smoothly on it, and the sealing performance can also be guaranteed.

[0059] In some embodiments, the colloid includes a glue layer and a lubricating coating applied on the surface of the glue layer. In one embodiment, the glue layer can be a polyurethane glue layer, and the lubricating coating can be an aqueous silicone-modified polyurethane resin layer. The surface of the lubricating coating is smooth, with a low friction coefficient, good wear resistance, and good weather resistance, which can effectively reduce problems such as abnormal noise or difficult lifting caused by the friction between the inner water cut and the auxiliary transition plate 14 during the glass lifting process. It is easy to understand that the materials of the glue layer and the lubricating coating in this application are not limited to this, and other equivalent alternative materials that can achieve the same functional level should not exceed the protection scope of this application.

[0060] Specifically, when the auxiliary transition plate 14 is made of a colloid, the shape (such as the inclined plane and / or contour, etc.) of the auxiliary transition plate 14 can be finally formed by a scraper after applying glue on the laminated glass 10. Using a colloid to make the auxiliary transition plate 14 can achieve a seamless structure between the auxiliary transition plate 14 and the lower edge line 11 of the inner sheet glass 11, preventing problems such as abnormal noise of the water cut sliding and lifting blockage caused by the gap.

[0061] It is easy to understand that when the colloid includes a glue layer and a lubricating coating applied on the surface of the glue layer, the object of the action of the scraper should be the glue layer itself, and the surface lubricating coating is applied after the glue layer is formed to avoid damaging the coating.

[0062] Specifically, in one embodiment, the material used for the auxiliary transition plate 14 is PBT (polybutylene terephthalate), PA66 (Polyadiohexylenediamine, polyhexamethylene adipamide, alias: nylon-66, polyamide-66), POM (Polyoxymethylene (Polyformaldehyde), polyoxymethylene resin), EPDM (Ethylene Propylene Diene Monomer, ethylene propylene diene monomer), or PVC (Polyvinylchloride, polyvinyl chloride).

[0063] In certain embodiments, the intermediate connection layer 13 is a PVB material layer.

[0064] In some other embodiments of the present application, a vehicle door is provided, which includes an inner water deflector and the laminated glass 10 with a transition structure described in any of the above items. The inner water deflector presses against the inner side of the laminated glass 10. By adopting the laminated glass 10 with a transition structure described in any of the above embodiments, while ensuring good sealing performance between the inner water deflector and the laminated glass 10, the laminated glass 10 has excellent optical performance. Specifically, after adding the auxiliary transition plate 14, the lower edge line 111 of the inner glass 11 can be designed as a straight line, so that there will be no wavy edge during the processing of the inner glass 11, and finally the laminated glass 10 obtained after lamination has excellent optical performance. The auxiliary transition plate 14 is used to abut and seal with the inner water deflector to ensure good sealing performance.

[0065] Further, in some other embodiments, the vehicle door further includes an outer water deflector, which abuts against the outer side of the laminated glass 10, and the height of the outer water deflector is greater than the height of the inner water deflector.

[0066] In still some other embodiments, a vehicle is provided, which includes the above-mentioned vehicle door. Since the vehicle adopts the vehicle door described in any of the above embodiments, the laminated glass 10 of the vehicle has good sealing performance during lifting and lowering, excellent optical performance of the vehicle window, and the market competitiveness is improved.
