Description

Technical Field

[0001] This utility model relates to the field of glass production technology, and in particular to a laminated glass and a vehicle. Background Technology

[0002] In recent years, with the rapid development of economy and technology, laminated glass has begun to be widely used in various scenarios to achieve various types of functions. For example, in the current automotive field, there are laminated glass technologies such as dimming, heat insulation, heating and display on automotive sunroofs. By sealing various functional components inside the laminated glass, the laminated glass can play additional functions.

[0003] However, due to the large size of automotive sunroof glass, wrinkles and bubbles are prone to occur during the actual production of laminated glass. To address these technical problems, in the existing technology, Chinese invention patent CN115362139B, published on October 29, 2024, entitled "Laminated Glass," provides a new laminated glass structure. This structure divides the internal functional components into two parts within a single piece of glass, controlling the distance between the two functional components to be more than 15mm. A resin layer is then used to fill the gap between the two functional components, thereby reducing the problem of wrinkles in the laminated glass.

[0004] Research has found that while the existing patents can effectively solve the wrinkle problem during laminated glass assembly, when the gap between the two functional components is too small, there are still problems such as difficulty in positioning the edge patch and low assembly efficiency.

[0032] 4. Second intermediate membrane;

[0033] 5. Edge patching film;

[0034] 6. Primary functional component;

[0035] 7. Secondary functional component. Detailed Implementation

[0036] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0037] like Figures 1-4 As shown, this utility model designs a new type of laminated glass, which includes an outer glass 1 and an inner glass 2, and the outer glass 1 and the inner glass 2 are stacked. In this laminated glass, a sandwich member is also provided, which is disposed between the outer glass 1 and the inner glass 2. The sandwich member specifically includes a first functional component 6 and a second functional component 7, so that the side of the first functional component 6 close to the second functional component 7 can establish a concave-convex matching connection relationship with the second functional component 7.

[0038] In this invention, to ensure that the first functional component 6 and the second functional component 7 can establish a concave-convex matching connection, in practical applications, multiple protrusions can be formed on the first functional component 6 and the second functional component 7, and these protrusions are all along the length direction of the laminated glass (e.g., ...). Figure 1 or Figure 2As shown in the X-direction extension configuration, in this case, the two adjacent protrusions can be surrounded to form a groove, so as to accommodate the protrusion on another functional component.

[0039] It should be noted that, in this embodiment, the shape of the groove and the shape of the protrusion are not specifically limited, for example: see Figure 1 As shown, the shape of the groove and the shape of the protrusion can specifically be an arc-shaped teardrop; see also Figure 2 As shown, the shape of the groove and the shape of the protrusion can be trapezoidal; however, it should be noted that regardless of the shape of the protrusion, it can be accommodated in the groove of another functional component.

[0040] At this time, in order to improve the stability of the first functional component 6 and the second functional component 7 when they are connected in a concave-convex matching manner, in practical applications, the structure of the groove portion on the first functional component 6 and / or the second functional component 7 is also optimized, that is, the groove inner size of at least part of the groove portion is controlled to be larger than the groove opening size of the groove portion; based on this design, after the first functional component 6 and the second functional component 7 are connected in a concave-convex matching manner, the protrusion portion corresponding to the groove portion will not come out from the groove opening of the groove portion.

[0041] Meanwhile, in order to further improve the stability of the first functional component 6 and the second functional component 7 when they are connected in a concave-convex matching manner, after the first functional component 6 and the second functional component 7 are combined in a concave-convex matching manner, they can be fixed by means of tape or electric welding, so that the two functional components will not come out or the concave-convex matching will fail after being combined, thus making the subsequent assembly process more convenient.

[0042] Accordingly, after establishing the stable connection structure of the aforementioned interlayer, considering the problem that the interlayer located between the outer glass 1 and the inner glass 2 is prone to wrinkling during subsequent lamination; in this utility model, the aforementioned interlayer is also designed along the first direction ( Figure 1 or Figure 2 Openings are provided at both ends of the X-direction shown. Specifically, the openings are provided between the first functional component 6 and the second functional component 7. That is, openings are provided at both ends of the connection area between the first functional component 6 and the second functional component 7, and the openings are filled with edge-patterning films 5 to solve problems such as wrinkles and bubbles.

[0043] Among them, Figure 1 or Figure 2In the illustrated embodiment, the X direction, as the first direction, specifically refers to the length direction of the laminated glass of this invention. In some other embodiments, the first direction can be specifically selected as the width direction of the laminated glass of this invention. Of course, this invention does not specifically limit it, and the production end can adaptively select a suitable direction according to specific production needs.

[0044] It should be noted that in practical applications, the laminated glass specifically combines the first functional component 6 and the second functional component 7 into a complete membrane to obtain a complete laminate. The matching relationship between the two determines that air bubbles will not be trapped between the two functional components. At the same time, since the two ends of the laminate are also provided with edge-fitting membranes 5 between the first functional component 6 and the second functional component 7, they can effectively limit the shape of the laminate and avoid wrinkles. They also make it difficult for air bubbles to be trapped in the opening between the two functional components.

[0045] See Figure 3 and Figure 4 As shown, in this invention, the designed interlayer is typically used in laminated glass with a certain curvature to avoid wrinkles and bubbles during lamination. In practical applications, the edge-patching film 5 can be specifically arranged around the interlayer, and at least a portion of the edge-patching film 5 can fill the openings at both ends of the interlayer in the first direction.

[0046] Furthermore, in order to ensure uniform thickness, when actually selecting the above-mentioned edge-patching diaphragm 5, it is necessary to specifically control the thickness settings of the above-mentioned edge-patching diaphragm 5, the first functional component 6, and the second functional component 7.

[0047] See also Figures 3-4 It can be seen that, in order to meet the needs of practical applications, the designed laminated glass is specifically provided with a first interlayer 3 and a second interlayer 4. The first interlayer 3 and the second interlayer 4 are both provided between the outer glass 1 and the inner glass 2, and the first interlayer 3 is specifically connected to the outer glass 1, and the second interlayer 4 is specifically connected to the inner glass 2. At this time, the laminated component is specifically provided between the first interlayer 3 and the second interlayer 4, and is connected to the first interlayer 3 and the second interlayer 4 respectively. That is to say, the first functional component 6 and the second functional component 7 are provided between the first interlayer 3 and the second interlayer 4.

[0048] In practical applications, the aforementioned first functional component 6 and second functional component 7 include at least one of the following: a light-adjusting layer, a heat-insulating layer, a radiation-resistant layer, a sound-insulating layer, and an antenna layer. Manufacturers can select appropriate film layers as the aforementioned first functional component 6 and second functional component 7 according to the specific usage requirements of the product, so that the laminated glass can achieve different functions according to the user's needs.

[0049] In this embodiment, the first intermediate film 3 and the second intermediate film 4 can be specifically selected as PVB films. Of course, in some preferred embodiments, other polyester films, such as PET films or PC films, can also be specifically selected. This utility model does not impose any special limitations on this. Manufacturers can select appropriate films according to specific production needs.

[0050] Accordingly, in this embodiment, the first functional component 6 and the second functional component 7 in the aforementioned interlayer can each be a dimming film, and can be at least one of the following: PDLC (polymer dispersed liquid crystal) dimming film, PSLC (polymer stabilized liquid crystal) dimming film, and EC (electrochromic) dimming film, which can integrate multiple functions, such as heating, heat insulation, and display functions. Of course, in practical applications, it is not limited to the integration of the above functions. In some specific embodiments, a separate non-dimming functional film can also be selected to achieve other functions.

[0051] For example, in some specific embodiments, the first functional component 6 can be specifically selected as a PDLC dimming film to achieve dimming display function by dispersing liquid crystal molecules in a polymer matrix; the second functional component 7 can be specifically selected as an EC dimming film to change the optical properties of the film through an electrochemical reaction. When a voltage is applied, the color and transparency of the film change, thereby achieving dimming display function.

[0052] It should be noted that, in order to ensure better practical application results, in this utility model, preferably, the thicknesses of the first intermediate film 3, the second intermediate film 4, the first functional component 6, the second functional component 7 and the edge patching film 5 can be controlled to be between 0.36mm and 0.78mm respectively.

[0053] Of course, the thicknesses of the first functional component 6 and the second functional component 7 can be controlled between 5µm and 360µm respectively. In practical applications, depending on the specific application requirements, the outer glass 1 and the inner glass 2 can be selected as glass of uniform thickness, and the thicknesses of the outer glass 1 and the inner glass 2 can preferably be set between 1.8mm and 4mm respectively. Of course, in some specific embodiments, considering the application of ultra-thin glass, the minimum thickness of the outer glass 1 or the inner glass 2 can be specifically selected as 0.8mm according to the actual application requirements. At this time, a certain protective effect can be achieved, and the application requirements can also be met.

[0054] Accordingly, the laminated glass described above can be specifically applied to vehicles, for example, as a car sunroof, installed on the roof of a car to effectively meet the multifunctional needs of the automotive industry.

[0055] In summary, it can be seen that the laminated glass designed using this utility model has a sandwich component specifically provided between the inner glass 2 and the outer glass 1, and the sandwich component includes a first functional component 6 and a second functional component 7, so that the first functional component 6 can be matched and connected with the second functional component 7 in a concave-convex manner. After the two functional components are combined, there will be no problem of detachment or failure of concave-convex matching, thus making the subsequent lamination process simpler. At the same time, the laminated glass also has openings at both ends of the sandwich component along the first direction, so that the edge patching film 5 is filled in the openings, thereby effectively solving the problem of wrinkles and air bubbles inside existing laminated glass during lamination. It has good prospects for promotion and application value.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
