Glass assemblies, door and window assemblies and vehicles

Abstract

This application relates to a glass assembly, a door and window assembly, and a vehicle. The glass assembly includes a glass panel and a fixing block. The fixing block is connected to the bottom of the outer side of the glass panel and is located at the middle of the glass panel along its length. The fixing block is used to abut against a door hinge to maintain the distance between the door and the glass panel along the thickness direction of the glass. Because the fixing block is located at the bottom of the outer side of the glass panel, and abuts against the door hinge, it provides a compressive force on the glass from the outside to the inside, counteracting the compressive force exerted by the inner sealing strip on the glass from the outside. This effectively prevents the glass from arching or bending outwards due to insufficient rigidity, thus making the distance between the glass and the door panel more uniform along the length direction of the door, ensuring that the distance between the glass and the door meets the requirements.

Description

Technical Field

[0001] This application relates to the field of transportation technology, and in particular to a glass assembly, a door and window assembly, and a vehicle. Background Technology

[0002] With the rapid development of transportation technology, taking automobiles as an example, water-resistant seals are typically installed between the doors and windows as one of the most important sealing strips in the door and window assembly. When in use, the water-resistant seal adheres closely to the glass to achieve functions such as waterproofing, dustproofing, shock absorption, and sealing. Based on the ever-increasing demands for aesthetics, aerodynamic performance, and sealing in automotive design, concealed water-resistant seals will be increasingly widely used in various vehicle models, no longer limited to high-end or new energy vehicles. However, when the glass is raised to its highest point, the gap between the glass and the door exhibits unevenness along the length of the door. Summary of the Invention

[0003] Therefore, it is necessary to address the shortcomings of existing technologies by providing a glass assembly, door and window assembly, and vehicle that enables the gap between the glass and the door to be more uniform along the length of the door when the glass is raised to its highest position.

[0004] On one hand, this application provides a glass assembly, comprising:

[0005] Glass; and

[0006] A fixing block is attached to the bottom of the outer side of the glass and is located at the middle part of the glass along its length; the fixing block is used to abut against the door fittings to maintain the distance between the door and the glass along the thickness direction of the glass.

[0007] In one embodiment, the fixing block has a pressing surface located on the side of the fixing block opposite to the glass, and the distance between the pressing surface and the glass increases along the direction from the top to the bottom of the glass.

[0008] In one embodiment, the pressing surface includes a plane that is angled to the outer surface of the glass; or, the pressing surface includes an arcuate surface.

[0009] In one embodiment, the fixing block is a wedge-shaped block, and the pressing surface is the wedge-shaped surface of the wedge-shaped block; the side of the wedge-shaped block connected to the outer side of the glass is a rectangular surface, and the long side of the rectangular surface is parallel to the driving direction.

[0010] In one embodiment, the design parameters of the wedge block satisfy the following formula:

[0011]

[0012] Wherein, E is the elastic modulus of the glass material, t is the total thickness of the glass, A is the wedge angle of the wedge block, L is the length of the rectangular surface, W is the width of the rectangular surface, σ is the correction parameter, and K is the critical stiffness constant of the glass.

[0013] In one embodiment, 1 ≤ L / W ≤ 20.

[0014] In one embodiment, 100mm 2 ≤L*W≤8000mm 2 .

[0015] In one embodiment, 0° < A ≤ 40°.

[0016] In one embodiment, the glass assembly further includes an adhesive layer through which the fixing block is connected to the outer surface of the glass.

[0017] In one embodiment, the fixing block includes a main body block and a connecting block, the main body block being connected to the adhesive layer via the connecting block; the connecting block is made of a plastic material compatible with the adhesive layer, and / or, the main body block is made of a wear-resistant and noise-resistant plastic material.

[0018] In one embodiment, the fixing block is directly connected to the adhesive layer, and the fixing block is made of a plastic material that is compatible with the adhesive layer and is noise-resistant and wear-resistant.

[0019] In one embodiment, the glass is a single glass sheet with a thickness of t, where 3.0 mm ≤ t ≤ 5 mm.

[0020] In one embodiment, the glass is laminated glass, which includes two glass plates stacked together; wherein the thickness of each glass plate is 1.3 mm to 3.0 mm; or, one glass plate has a thickness of 0.7 mm to 2 mm and the other glass plate has a thickness of 2 mm to 3 mm.

[0021] On the other hand, this application also provides a door and window assembly, including the glass assembly described above. The door and window assembly further includes a vehicle door, an inner water cutter, and an outer water cutter. The vehicle door forms a movable chamber, and the glass assembly is vertically and vertically disposed in the movable chamber. The inner water cutter and the outer water cutter are both located in the movable chamber. The outer water cutter is connected to the vehicle door and has a first lip, which abuts against the outer surface of the glass. The inner water cutter is connected to the vehicle door and has a second lip, which abuts against the inner surface of the glass.

[0022] In one embodiment, there are at least two first lips, which are arranged sequentially along the lifting direction of the glass assembly, and the bottommost first lip is the door hinge.

[0023] In one embodiment, the door and window assembly further includes a first sealing strip, which is disposed at the top of the door. The first sealing strip has a first sealing part and a second sealing part. The first sealing part is in sealing contact with the inner side of the glass, and the second sealing part is in sealing contact with the outer side of the glass.

[0024] In one embodiment, the door and window assembly further includes two second sealing strips, which are respectively connected to opposite sides of the vehicle door, and the second sealing strips are in sealing contact with the inner surface of the glass.

[0025] Furthermore, this application also provides a means of transportation, which includes the door and window assembly of any of the above embodiments.

[0026] The aforementioned glass assembly, door and window assembly, and vehicle have a fixing block at the bottom of the outer side of the glass. The fixing block abuts against the door fittings and provides a compressive force on the glass from the outside to the inside to counteract the compressive force of the inner sealing strip on the glass from the outside. This effectively prevents the glass from arching and bending outward due to insufficient rigidity, and makes the distance between the glass and the door more uniform along the length of the door, thus ensuring that the distance between the glass and the door meets the requirements.

[0036] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] It should be noted that the means of transportation in this embodiment include, but are not limited to, automobiles, buses, trains, and high-speed trains. This embodiment specifically uses automobiles as an example, but it is not limited to this.

[0038] It should be noted that in this embodiment, left, right, front, and rear are all based on the vehicle's normal driving on the road surface. Along the direction of travel, the part closer to the front of the vehicle is the front, and the part closer to the rear is the rear. Along a direction perpendicular to the direction of travel and parallel to the ground, the part closer to the left door is the left side, and the part closer to the right door is the right side. The length direction of the vehicle refers to the direction of the line connecting the center of the front and rear of the vehicle. The width direction of the vehicle refers to the direction of the line connecting the center of the left and right doors.

[0039] It should be noted that, in this embodiment, the length direction of the door refers to the direction of the door that is parallel to the length direction of the vehicle body when the door is normally closed to the vehicle body.

[0040] It should be noted that, in this embodiment, the outer side of the glass refers to the side of the glass facing the external environment of the vehicle; the inner side of the glass refers to the side of the glass facing the internal environment of the vehicle, that is, the side of the glass away from the outer side.

[0041] As mentioned in the background art, in related technologies, when the glass is raised to its highest position, the gap between the glass and the car door is uneven along the length of the door. This problem arises because, in these technologies, when the glass is raised to its highest position, the inner edge of the glass (specifically including the left, right, and top sides of the inner surface of the glass) abuts against the inner sealing strip of the door, while the outer edge of the glass (specifically including the top side of the outer surface of the glass) abuts against the outer sealing strip of the door. The pressure exerted on the glass by the inner sealing strip is typically greater than the pressure exerted by the outer sealing strip. Furthermore, with the increasing demand for lightweight automotive design, the thickness of the glass is gradually decreasing to reduce weight. However, reducing the glass thickness leads to a decrease in stiffness. Once the stiffness of the glass decreases, and under the outward pressure of the inner sealing strip, the glass will bend and deform, causing the middle part of the glass to arch towards the outside of the car. For concealed water deflectors, the uneven gap between the door and the glass along the length of the door is a defect that can be directly observed from both inside and outside the vehicle.

[0042] For the reasons mentioned above, this application provides a glass assembly, a door and window assembly, and a vehicle that enables the gap between the glass and the door to be relatively uniform along the length of the door when the glass is raised to its highest position.

[0043] Please see Figure 1 , Figure 1 This is a schematic diagram of a vehicle provided in an embodiment of this application. The vehicle may include a body 10 and a door and window assembly 20. The door and window assembly 20 is mounted on the body 10.

[0044] Specifically, the door and window assembly 20 includes, but is not limited to, the front door and window assembly, the rear door and window assembly, etc., and is not limited here. It can be set according to actual needs.

[0045] It should be noted that, Figure 1 The purpose of this illustration is merely to depict the connection relationship between the door and window assembly 20 and the vehicle body 10, and is not to specifically limit the connection positions, specific structures, or quantities of each device. In other embodiments of this application, the vehicle may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The components illustrated may be implemented in hardware, software, or a combination of software and hardware.

[0046] Please see Figure 1and Figure 2 , Figure 2 It shows Figure 1 Sectional view of the structure at point AA.

[0047] For example, the door and window assembly 20 includes a glass assembly 21. The glass assembly 21 is specifically a side window glass assembly.

[0048] Please see Figure 1 , Figures 6 to 8 The glass assembly 21 includes glass 211, which can be a single-layer glass plate. The single-layer glass plate can be, for example, tempered glass or ordinary glass. Research has found that when the thickness of the single-layer glass plate is less than 3.2 mm, the stiffness of glass 211 is too low to meet requirements; when the thickness of the single-layer glass plate is greater than 5 mm, the stiffness of glass 211 can be improved, but the weight of glass 211 will increase. Therefore, in order to reduce the thickness of glass 211 to achieve a lightweight design, while preventing the stiffness of glass 211 from being too low to meet requirements, the thickness of the single-layer glass plate can optionally be, but is not limited to, 3.2 mm to 5 mm, specifically, for example, 3.2 mm, 3.6 mm, 4 mm, 4.5 mm, or 5 mm. Of course, it is understood that in some optional solutions, the thickness of the single-layer glass plate in this embodiment can also be set to any value less than 3.2 mm and greater than 5 mm, and is not limited here.

[0049] For example, in this embodiment, the glass 211 is not limited to a single-layer glass plate, but can also be at least two glass plates stacked together; in other words, the glass 211 can be laminated glass, and the number of layers in the laminated glass can be, for example, two, three or more layers. Please refer to [further details omitted]. Figures 6 to 8In this embodiment, the laminated glass will be specifically described as having two layers, but this is not a limitation. The laminated glass includes a first glass plate 2111, an intermediate composite layer 2112, and a second glass plate 2113 stacked sequentially. The first glass plate 2111 has a first surface and a second surface arranged opposite to each other, and the second glass plate 2113 has a third surface and a fourth surface arranged opposite to each other. The second surface and the third surface are arranged opposite to each other and connected by the intermediate composite layer 2112. The first surface faces the external environment of the vehicle, and the fourth surface faces the internal environment of the vehicle. The intermediate composite layer 2112 can be made of polyvinyl butyral (PVB), polycarbonate (PC), sound-insulating PVB, light-shielding PVB, heat-controlling PVB, ethylene vinyl acetate (EVA), thermoplastic polyurethane (TPU), ionomers, thermoplastic materials, polybutylene terephthalate (PBT), polyethylene vinyl acetate (PET), polyethylene naphthalate (PEN), polyvinyl chloride (PVC), polyvinyl fluoride (PVF), polyacrylate (PA), polymethyl methacrylate (PMMA), polyurethane (PUR), and combinations thereof. In this embodiment, the glass 211 is specifically, for example, laminated glass, which, compared to a single-layer glass panel, has superior properties including, but not limited to, greater stiffness and better sound insulation and noise reduction effects.

[0050] Research has shown that for the stacked glass plates, a thickness less than 2.0 mm results in insufficient stiffness, making them prone to breakage and failing to meet requirements. A thickness greater than 3.2 mm improves the stiffness of the glass 211, but increases its weight. For example, the thickness of each stacked glass plate is flexibly adjusted and set according to actual needs, and includes, but is not limited to, 2.0 mm to 3.2 mm. Specifically, the thicknesses of the stacked glass plates are, for example, 2.0 mm, 2.1 mm, 2.3 mm, 2.5 mm, 2.8 mm, 3.0 mm, or 3.2 mm. Of course, it is understood that in some alternative solutions, the thickness of each stacked glass plate in this embodiment can also be set to any value less than 2.0 mm and greater than 3.2 mm, and is not limited here.

[0051] For example, the door and window assembly 20 also includes a door 22. The door 22 can be a front door or a rear door, or it can be a flip-open type or a sliding push-pull type door 22, etc. There is no limitation here, and it can be set and adjusted according to actual needs.

[0052] The door 22 has a movable chamber 221. The glass assembly 21 is movably mounted in the movable chamber 221. When the glass assembly 21 is lowered, the glass 211 of the door and window assembly 20 is opened, allowing the interior and exterior environments of the vehicle to communicate with each other. When the glass assembly 21 is raised to its highest point, the glass 211 of the door and window assembly 20 is closed, and the door and window assembly 20 isolates the interior and exterior environments of the vehicle, providing sound insulation, noise reduction, and rain protection.

[0053] Please refer to the following: Figure 2 For example, the door and window assembly 20 also includes a water cutter. The water cutter specifically includes an inner water cutter 212 and an outer water cutter 213. In this embodiment, the water cutter is concealed, so both the inner water cutter 212 and the outer water cutter 213 are located within the movable chamber 221, thus not being observed by people inside or outside the vehicle.

[0054] The outer water cutter 213 is connected to the door 22, and the outer water cutter 213 is provided with a first lip 2131. The first lip 2131 abuts against the outer side of the glass 211. In this way, when the glass 211 is raised or lowered, the outer water cutter 213 can scrape away water mist, water droplets and dust on the outer side of the glass 211, achieving the functions of waterproofing, dustproofing, shock absorption and sealing.

[0055] Similarly, the inner water cutter 212 is connected to the door 22. The inner water cutter 212 is provided with a second lip 2121, which abuts against the inner side of the glass 211. In this way, when the glass 211 is raised or lowered, the inner water cutter 212 can scrape away water mist, water droplets and dust on the inner side of the glass 211, achieving the functions of waterproofing, dustproofing, shock absorption and sealing.

[0056] The number of first lips 2131 is not limited, for example, one, two, three or more. When there are at least two first lips 2131, the at least two first lips 2131 are arranged sequentially along the lifting direction of the glass assembly 21. In this way, when the at least two first lips 2131 abut against the outer surface of the glass 211, at least two seals are formed, which has good sealing performance.

[0057] Similarly, the number of second lips 2121 is not limited, for example, one, two, three or more. When there are at least two second lips 2121, the at least two second lips 2121 are arranged sequentially along the lifting direction of the glass assembly 21. In this way, when the at least two second lips 2121 abut against the inner surface of the glass 211, at least two seals are formed, which has better sealing performance.

[0058] The door 22 includes an outer door panel 222 and an inner door panel 223. The outer door panel 222 is connected to the inner door panel 223, and the outer door panel 222 and the inner door panel 223 are spaced apart to enclose and form a movable cavity 221.

[0059] In this embodiment, the distance between the door 22 and the glass 211 refers to the distance between the outer door panel 222 and the outer side of the glass 211, specifically as follows: Figure 2 As shown in S1. Of course, it can also be understood as the distance between the inner door panel 223 and the inner side of the glass 211, specifically as shown in... Figure 2 As shown in S2. Because the positions of the outer door panel 222 and the inner door panel 223 are relatively fixed, when the distance S1 between the outer door panel 222 and the outer side of the glass 211 remains constant along the length of the door 22, the distance S2 between the inner door panel 223 and the inner side of the glass 211 also remains constant along the length of the door 22. Conversely, as in the background art, the middle part of the glass 211 is curved and arched towards the outside of the vehicle, so that the distance S1 between the outer side of the glass 211 and the outer door panel 222 has a tendency to first decrease and then increase along the length of the door 22. Correspondingly, the distance S2 between the inner side of the glass 211 and the inner door panel 223 has a tendency to first increase and then decrease along the length of the door 22.

[0060] To improve the uniformity of the gap between the door 22 and the glass 211 along the length of the door 22, the glass assembly 21, for example, further includes a fixing block 23. The fixing block 23 is connected to the bottom of the outer side of the glass 211, and is located at the middle portion of the glass 211 along its length. It should be noted that the middle portion in this embodiment is not strictly the exact center, but rather, with a reference to the exact center, it may have a deviation of, for example, ±1 / 3 of the length of the glass 211 relative to the exact center. The fixing block 23 is used to abut against the door mechanism to maintain the gap between the door 22 and the glass 211 along the thickness direction of the glass 211.

[0061] Specifically, the door fitting is, for example, the first lip 2131 of the outer water cutter 213, and when the glass assembly 21 is raised to the top of the door 22, the fixing block 23 abuts against the first lip 2131 to maintain the distance between the door 22 and the glass 211 along the thickness direction of the glass 211.

[0062] Of course, in some other embodiments, the door's connecting member is not limited to using the first lip 2131 to abut against the fixing block 23. It can also use any other structure on the door, as long as it is located below the outer water cutter and serves as a spacer. There are no limitations here.

[0063] For example, the number of fixing blocks 23 may be one or more, and the specific number is not limited here. When there are multiple fixing blocks 23, the multiple fixing blocks 23 are arranged sequentially along the length direction of the glass 211.

[0064] The aforementioned glass assembly 21 has a fixing block 23 at the bottom of the outer side of the glass 211. The fixing block 23 abuts against the door fittings and provides a squeezing force on the glass 211 from the outside to the inside to counteract the squeezing force of the inner sealing strip on the glass 211 from the outside to the inside. This effectively prevents the glass 211 from arching and bending outward due to insufficient rigidity. As a result, the distance between the glass 211 and the door 22 is more uniform along the length of the door 22, thus ensuring that the distance between the glass 211 and the door 22 meets the requirements.

[0065] It should be noted that the fixing block 23 can be fixedly connected to the glass 211 by means including but not limited to adhesive, welding, riveting, snap-fitting, or fasteners such as screws and pins. The specific method can be flexibly adjusted and set according to actual needs, and is not limited here. To facilitate the installation of the fixing block 23 on the glass 211, for example, the fixing block 23 is connected to the outer surface of the glass 211 by adhesive. Specifically, the glass assembly 21 also includes an adhesive layer 24, through which the fixing block 23 is connected to the outer surface of the glass 211.

[0066] Please refer to the following: Figure 7 For example, the fixing block 23 may be made of a combination of two or more materials, specifically including a main block 231 and a connecting block 232. The main block 231 is connected to the adhesive layer 24 via the connecting block 232, meaning the connecting block 232 connects the main block 231 and the adhesive layer 24. Optionally, the connecting block 232 is made of a plastic material compatible with the adhesive layer 24. This ensures a stable connection between the connecting block 232 and the adhesive layer 24. Furthermore, since both the connecting block 232 and the main block 231 are made of plastic, they can be firmly bonded together. Specifically, the connecting block 232 and the main block 231 can be integrally injection molded.

[0067] Based on the foregoing embodiments, when the material of the connecting block 232 is, for example, ABS, the material of the adhesive layer 24 is, for example, epoxy resin, cyanoacrylate (fast-drying adhesive), or polyurethane; when the material of the connecting block 232 is, for example, PC (polycarbonate), the material of the adhesive layer 24 is, for example, modified silane adhesive (MS adhesive) or UV-curable adhesive; when the material of the connecting block 232 is, for example, rigid PVC, the material of the adhesive layer 24 is, for example, polyurethane adhesive (PU) or solvent-based adhesive; when the material of the connecting block 232 is, for example, PMMA (acrylic), the material of the adhesive layer 24 is, for example, UV adhesive or epoxy adhesive.

[0068] Based on the aforementioned embodiments, the main body block 231 is made of plastic material, specifically, for example, a wear-resistant and noise-reducing plastic material. Thus, the main body block 231 possesses wear-resistant and noise-reducing properties. Optionally, the material of the main body block 231 may include, but is not limited to, various materials such as POM (polyoxymethylene) or wear-resistant TPE.

[0069] Of course, please see Figure 8 In some embodiments, the fixing block 23 may also be made of a single material. Specifically, the fixing block 23 is directly connected and fixed to the adhesive layer 24. The fixing block 23 is made of a plastic material that is compatible with the adhesive layer 24 and is noise-resistant and wear-resistant. In this way, the fixing block 23 can be easily connected and fixed to the adhesive layer 24, and can prevent noise during contact with the first lip 2131, and has good wear resistance and long service life. Optionally, the fixing block 23 may be made of a composite material including POM (polyoxymethylene) and PTFE (polytetrafluoroethylene) or other materials, which are not limited here and can be selected according to actual needs.

[0070] Please see Figure 2 In one specific embodiment, when there are at least two first lips 2131, the at least two first lips 2131 are arranged sequentially along the lifting direction of the glass assembly 21. The fixing block 23, for example, abuts against the bottommost first lip 2131. That is, the bottommost first lip 2131 serves as a door latch. Thus, the fixing block 23 can be obscured by the remaining first lips 2131, preventing it from being observed by occupants inside or outside the vehicle.

[0071] Please see Figure 2 For example, the fixing block 23 is provided with a pressing surface 233, which is located on the side of the fixing block 23 opposite to the glass 211. The distance between the pressing surface 233 and the glass 211 increases from the top to the bottom of the glass 211. Thus, during the process of the glass assembly 21 rising to the top of the door 22, the fixing block 23 abuts against the first lip 2131 through the pressing surface 233. Since the distance between the pressing surface 233 and the glass 211 increases from the top to the bottom of the glass 211, it is easy for the first lip 2131 to open. Furthermore, the pressing force exerted by the first lip 2131 on the fixing block 23 gradually increases as the fixing block 23 rises, and the corresponding outward pressing force exerted by the fixing block 23 on the glass 211 gradually increases, which can balance the outward pressing force exerted by the inner sealing strip on the glass 211. In addition, it can effectively prevent the glass 211 from cracking or the fixing block 23 from falling off due to the sudden change in the compressive force of the fixing block 23.

[0072] For example, the pressing surface 233 in this embodiment includes, but is not limited to, one or any combination of a plane 2331, a curved surface, and a polygonal surface. The specific form can be adjusted and set according to actual needs, and is not limited here. The curved surface includes, but is not limited to, an arc-shaped surface or an S-shaped surface.

[0073] In this embodiment, the pressing surface 233 preferably includes a plane 2331, which is set at an angle to the outer surface of the glass 211. In this way, during the pressing process between the pressing surface 233 and the first lip 2131, the noise generated is small due to the flat surface, and it is also resistant to friction.

[0074] Please see Figure 7 Based on the aforementioned embodiments, the pressing surface 233 further includes a transition surface 2332. The transition surface 2332 connects the top end face of the fixing block 23 to the plane 2331, and the top end face of the fixing block 23 smoothly transitions to the plane 2331 through the transition surface 2332. Optionally, the transition surface 2332 is, for example, an arc-shaped surface, and the center of the arc-shaped surface is located on the side opposite to the first lip 2131. In other words, the top corner between the top end face of the fixing block 23 and the pressing surface 233 is chamfered. In this way, it can effectively prevent the glass 211 from cracking or the fixing block 23 from falling off due to the sudden change in the compressive force of the fixing block 23.

[0075] For example, the fixing block 23 is a wedge-shaped block, and the pressing surface 233 is the wedge-shaped surface of the wedge-shaped block. The side of the wedge-shaped block connected to the outer side of the glass 211 is a rectangular surface, and the long side of the rectangular surface is parallel to the driving direction, that is, it is set perpendicular to the direction from the top to the bottom of the glass 211.

[0076] For example, the design parameters of the wedge block satisfy the following formula:

[0077]

[0078] Where E is the elastic modulus of glass 211, in GPa, representing the stiffness of glass 211, which is an index that measures the material’s ability to resist elastic deformation.

[0079] t represents the total thickness of glass 211, in mm;

[0080] A is the wedge angle (°) of the wedge block, which is the angle between the pressing surface 233 and the outer surface of the glass 211;

[0081] L is the length of the rectangular surface;

[0082] W is the width of the rectangular face;

[0083] σ is a correction parameter used to reflect the redundancy design for actual process fluctuations (such as installation errors, aging, environmental fluctuations, etc.) to ensure safety under actual working conditions.

[0084] K is the critical stiffness constant of glass 211, in units of... .

[0085] It should be noted that the left side of the above formula, It can also be understood as the actual effective stiffness of glass 211 after compensation for fluctuations; on the right side of the above formula, K can also be understood as the safety stiffness of glass 211.

[0086] The "actual effective stiffness" of glass 211 after compensation for fluctuations was calculated and compared with K:

[0087] If the above formula holds true (left side ≥ right side): it means that the actual stiffness of glass 211 can cover the safety requirements. Even with process errors, aging, and environmental fluctuations, it can resist deformation and avoid failure, and glass 211 is in a safe state. Conversely, if the above formula does not hold true (i.e., left side < right side): it means that the "actual effective stiffness" of glass 211 is insufficient and cannot meet the safety threshold, posing a safety hazard. It is necessary to adjust the parameters to increase the "actual effective stiffness" of glass 211 to improve safety.

[0088] Based on the aforementioned embodiments, E includes, but is not limited to, 60 GPa to 75 GPa. For example, E can be 60 GPa, 62 GPa, 65 GPa, 66 GPa, 68 GPa, 70 GPa, 72 GPa, or 75 GPa, etc., and can be flexibly adjusted and set according to actual needs.

[0089] Based on the aforementioned embodiments, t ≥ 3.0 mm. Specifically, t can be 3.0 mm, 3.2 mm, 3.5 mm, 3.6 mm, 3.96 mm, 4 mm, 4.2 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, or 7.2 mm, etc., and can be flexibly adjusted and set according to actual needs.

[0090] Based on the aforementioned embodiments, 0° < A ≤ 40°. A can be, for example, 5°, 10°, 15°, 20°, 23°, 25°, 30°, 33°, 35°, or 40°, and can be flexibly adjusted and set according to actual needs. When A is greater than 40°, the lateral shear force component (force parallel to the contact surface) between the glass 211 and the fixing block 23 is relatively large, which can easily lead to the edge of the glass 211 detaching or localized stress concentration.

[0091] Based on the foregoing embodiments, 1≤ ≤20. Specific values ​​include 1, 3, 6, 8, 10, 13, 16, or 20, etc., which can be flexibly adjusted and set according to actual needs. Among them, when... When the value is greater than 20, the fixing block 23 is elongated, requiring a more precise match with the curved outer surface of the glass 211. This makes it difficult to install on the outer surface of the glass 211, increasing manufacturing difficulty and cost. When the value is less than 1, the bonding area between the fixing block 23 and the outer surface of the glass 211 is small, the fixing block 23 is easy to fall off, and the glass 211 is subjected to concentrated stress, which is prone to cracking defects.

[0092] Where L*W represents the product of L and W, referring to the contact area between the fixing block 23 and the glass 211. The size of L*W can affect the uniformity of force distribution on the glass 211. Optionally, 100mm 2 ≤L*W≤8000mm 2 For example, L*W is 100mm. 2 300mm 2 500mm 2 800mm 2 1300mm 2 3000mm 2 5000mm 2 Or 8000mm 2 The specific settings can be flexibly adjusted and configured according to actual needs. Specifically, when L*W > 8000mm 2 At that time, it will make

[0093] This makes the manufacturing process difficult, results in poor matching with the curved surface of 211 glass, high costs, excessive matching with water-cutting, large friction area, and a tendency to produce abnormal noise; when L*W < 100mm 2 When the contact area between the fixing block 23 and the glass 211 is small, the fixing block 23 is easy to fall off, and the glass 211 is subjected to concentrated force, which is prone to cracking defects.

[0094] The correction parameter σ compensates for the discrepancy between theoretical calculations and practical applications, ensuring the safe operation of the Glass 211 structure in complex real-world environments. Optionally, 1.2 ≤ σ ≤ 2.0. Specifically, σ can be, for example, 1.2, 1.5 / 1.8, or 2.0. When σ = 1.2, corresponding to the 3σ level, the pass rate is 93.3%; when σ = 2.0, corresponding to the 6σ level, the pass rate is 99.99966%.

[0095] Based on the aforementioned embodiments, 0 < K ≤ 3, and the value of K is related to the material and thickness of the glass 211. When the thickness of the glass 211 is increased, K can be increased; conversely, when the thickness of the glass 211 is decreased, K can be decreased.

[0096] It should be noted that, Characterizes the bending stiffness of glass 211 itself;

[0097] It should be noted that, This reflects the sensitivity of the fixed block 23 angle to the shear force (the shear force increases as A increases).

[0098] Based on the above formula, the following will address angle A and aspect ratio respectively. The impact of structural parameter compensation requirements is analyzed as follows:

[0099] 1. Angle A:

[0100] When A→40° An increase requires compensation adjustment by increasing t or E.

[0101] because It monotonically increases with increasing angle A (when A∈[0°,40°]). (Increased from 0 to approximately 0.64).

[0102] Therefore, when A→40°, the molecules in The increase is significant, directly improving the value on the left side of the formula.

[0103] The physical meaning of increasing the value of angle A includes:

[0104] Shear force sensitivity: The larger the wedge angle A, the greater the transverse shear force component (force parallel to the contact surface) between the glass 211 and the fixing block 23, which is more likely to cause the glass 211 edge to debond or local stress concentration.

[0105] Stiffness requirements: To resist greater shear forces, the bending stiffness of glass 211 needs to be increased. To compensate, otherwise the inequality may not be satisfied, leading to structural failure.

[0106] Why not adjust by reducing L or W to compensate?

[0107] Decreasing L or W will lower the denominator (contact area L·W), which may increase the value on the left side of the formula, but it will also lead to:

[0108] (1) Stress concentration: If the contact area is too small, it will increase the local pressure, which will increase the risk of glass 211 breaking;

[0109] (2) Aspect Ratio Constraint: L / W is limited to between 1 and 20. Excessive reduction of W will violate the design specifications. For example, if W is too narrow, the strength of the fixing block 23 will be insufficient.

[0110] Therefore, adjusting L / W is a secondary measure, while compensation via t or E is safer and more reliable.

[0111] In summary, when the wedge angle A → 40°:

[0112] (1) Increased shear force → higher stiffness required to resist deformation.

[0113] (2) The optimal compensation approach is to increase t (cubic effect) or E (linear effect) rather than sacrificing the contact area.

[0114] (3) This logic ensures that the formula balances mechanical safety and engineering feasibility.

[0115] 2. Aspect Ratio L / W: When L / W→20 (slender structure), the smaller W leads to a decrease in L*W, so it is necessary to increase t or select high E glass 211 to satisfy the inequality.

[0116] A decrease in the contact area L*W (for slender structures) leads to a decrease in the denominator, but an increase in the stiffness requirement.

[0117] If W decreases, L*W decreases → the value on the left side of the formula increases (which seems to make it easier to satisfy the inequality).

[0118] But why add t or E for compensation and adjustment?

[0119] Although mathematically reducing L*W makes the inequality easier to satisfy, the practical engineering problem is that:

[0120] (1) Stress concentration effect

[0121] The slender structure (with a very small W) leads to uneven load distribution. Local areas of glass 211 (near the narrow edge W) bear higher stress, making them prone to cracking or debonding. Even if the value on the left side of the formula is ≥ K, local stress may still exceed the limit, therefore the overall stiffness (E*) needs to be increased. (to compensate)

[0122] (2) The bending stiffness requirement increases, and the stability of the slender fixed block 23 (high L / W) is poor. It is more likely to twist or deflect when subjected to force, thus applying an additional bending moment to the glass 211.

[0123] Increasing t (thickness) or E (elastic modulus) can enhance the bending resistance of glass 211 and prevent glass 211 from breaking due to deformation of the fixing block 23.

[0124] (3) Physical meaning of the formula: The actual effective stiffness of glass 211 after compensation for fluctuations

[0125] This formula essentially requires the equivalent stiffness per unit contact area ( () must be ≥ K.

[0126] If L*W is too small, the force per unit area is greater, therefore a higher E* is required. To maintain the same safety margin.

[0127] Why not simply increase L*W to achieve compensation adjustment?

[0128] Although increasing W can increase the contact area, but:

[0129] (1) Limited by aspect ratio L / W≤20: If W increases, L may exceed the reasonable range. If the length L of the fixing block 23 is too large, it will not only affect the installation space, but also make the requirements of the single piece more stringent, thereby increasing the cost.

[0130] (2) Structural design constraints: Some applications (such as narrow bezel design) require W to be as small as possible, which can only be compensated by adjusting t or E.

[0131] In summary, when L / W ≤ 20 (slender structure):

[0132] (1) The contact area L*W decreases, but the risk of stress concentration increases, requiring higher stiffness to ensure safety.

[0133] (2) Optimal compensation method:

[0134] Increase the thickness of the glass by 211 (cubic magnification effect, most effective).

[0135] High-E glass 211 is selected (suitable for lightweight requirements).

[0136] (3) It is not possible to rely solely on mathematical relationships in formulas; optimization must be carried out in conjunction with actual stress distribution and structural stability.

[0137] For example, when glass 211 is a single glass plate, 3.0mm ≤ t ≤ 5mm. Optionally, t can be, for example, 3.0mm, 3.2mm, 3.4mm, 3.5mm, 3.6mm, 3.8mm, 4mm, 4.2mm, 4.5mm or 5mm, and can be flexibly adjusted and set according to actual needs, without limitation here.

[0138] For example, when glass 211 is laminated glass, and the laminated glass comprises two glass plates stacked together, the thickness of each glass plate is, for example, 1.3 mm to 3.0 mm. Optionally, the thickness of each glass plate may be the same or different, and may be, for example, 1.3 mm, 1.4 mm, 1.5 mm, 1.8 mm, 2 mm, 2.5 mm, or 3.0 mm, etc., which can be flexibly adjusted and set according to actual needs, and are not limited here.

[0139] For example, when glass 211 is laminated glass, and the laminated glass comprises two glass plates stacked together, one of the glass plates has a thickness of 0.7 mm to 2 mm, specifically, for example, 0.7 mm, 0.9 mm, 1.3 mm, 1.5 mm or 2.0 mm; and the other glass plate has a thickness of 2 mm to 3 mm, specifically, for example, 2 mm, 2.3 mm, 2.5 mm or 3.0 mm.

[0140] Please see Figure 3 For example, the door and window assembly 20 also includes a first sealing strip 25. The first sealing strip 25 is disposed at the top of the door 22. When the glass assembly 21 is raised to the top position of the door 22, the glass 211 and the first sealing strip 25 are sealed and abutted together, ensuring good sealing between the top edge of the glass 211 and the door 22. Specifically, the first sealing strip 25 has a first sealing part 251 and a second sealing part 252. The first sealing part 251 is sealed and abutted together with the inner side of the glass 211, and the second sealing part 252 is sealed and abutted together with the outer side of the glass 211.

[0141] Please see Figure 4 and Figure 5 The door and window assembly 20 also includes two second sealing strips 26. The two second sealing strips 26 are respectively connected to opposite sides of the door 22, and the second sealing strips 26 seal against the inner surface of the glass 211. Thus, when the glass assembly 21 is closed, both opposite sides of the glass 211 are sealed against the door 22 via the second sealing strips 26, thereby ensuring good sealing performance between the opposite sides of the glass 211 and the door 22.
