The first adhesive layer 13 is connected to the side of the first light-transmitting plate 11 facing the second light-transmitting plate 12. The second adhesive layer 14 is connected to a side surface of the second light-transmitting plate 12 facing the first light-transmitting plate 11, the second adhesive layer 14 and the first adhesive layer 13 are disposed at an opposing interval, in other words, the second adhesive layer 14 and the first adhesive layer 13 are not directly connected, and other members are disposed between the second adhesive layer 14 and the first adhesive layer 13. The functional layer 15 and the filling layer 16 are located on the same layer, and are provided between the first adhesive layer 13 and the second adhesive layer 14, and are connected to the first adhesive layer 13 and the second adhesive layer 14, respectively.
Specifically, the functional layer 15 includes, but is not limited to, one or more of a dimming layer, an illumination layer, a video layer, a display layer, a heating layer, and the like, and can be flexibly adjusted and set according to actual requirements. In this embodiment, the functional layer 15 is taken as an example of a dimming layer to be unfolded, the laminated glass 10 is correspondingly a dimming glass, and is specifically applied to sun-shading dimming glass, for example, the dimming layer can automatically adjust the intensity of light, and when the light outside the vehicle is stronger, the color of the functional layer 15 is darkened to play a role of light blocking.
The distance between the two sides of the first adhesive layer 13 and the second adhesive layer 14 facing away from each other is H. Furthermore, the filler layer 16 includes a first filler layer 161 located under the functional layer 15. The top side of the first filling layer 161 and the bottom side of the functional layer 15 are provided with a first gap 17, and the first gap 17 is S. Wherein 0<S is less than or equal to 3mm,1mm is less than or equal to H is less than or equal to 2mm, and S+H is less than or equal to 1.5mm and less than or equal to 4.5mm.
In the laminated glass 10, the first adhesive layer 13 and the second adhesive layer 14 are respectively connected to the opposite sides of the functional layer 15 and the filling layer 16, so that the structural strength can be improved, the laminated glass 10 is not easy to break down by foreign matters, and the safety is improved. In addition, it was found through experimental study that when 0<S.ltoreq.3mm, 1 mm.ltoreq.H.ltoreq.2mm, and 1.5 mm.ltoreq.S+H.ltoreq.4.5 mm, laminated glass 10 was not easily broken down by falling balls, and no significant bubbles were hardly seen at the position of first gap 17 (i.e., the position where the top edge of first filler layer 161 was spliced with the bottom edge of functional layer 15).
The laminated glass 10 may be either a front windshield, a side windshield, or a rear windshield.
Referring to FIGS. 1 and 2, in one embodiment, when 0<S is 1mm or less, H is 1.6mm or less, and 1.5mm or less, S+H is 3mm or less. Thus, when set in this range, it was found through a large number of experimental studies that the product was not broken down by the falling ball and no significant bubbles were seen at the first gap 17, and the total thickness of the laminated glass 10 was further reduced, so that the weight of the product was further reduced.
Referring to FIGS. 1 and 2, in one embodiment, when 1<S is 2mm or less, 1mm or less, H is 1.6mm or less, and 2mm or less, S+H is 4mm or less. Thus, when set in this range, it was found through a large number of experimental studies that the product was not broken down by falling balls, and no significant bubbles were found at the first gap 17.
Referring to FIGS. 1 and 2, in one embodiment, when 1<S is 2mm or less, 1mm or less, H is 1.6mm or less, and 2mm or less, S+H is 4mm or less. Thus, when set in this range, it was found through a large number of experimental studies that the product was not broken down by falling balls, and no significant bubbles were found at the first gap 17.
Referring to FIGS. 1 and 2, in one embodiment, when 2<S is equal to or less than 3mm,1mm equal to or less than H is equal to or less than 2mm, and 3mm equal to or less than S+H is equal to or less than 4mm. Thus, when set in this range, it was found through a large number of experimental studies that the product was not broken down by falling balls, and no significant bubbles were found at the first gap 17.
Referring to fig. 1 and 2, in one embodiment, when the laminated glass 10 is a front windshield, the functional layer 15 is disposed, for example, in an upper region 101 of the front windshield, so that the upper region 101 of the front windshield is formed as a light shielding region, and a lower region 102 of the front windshield is formed as a driver's field of view. Optionally, the area ratio of the upper region 101 to the lower region 102 of the front windshield can be flexibly adjusted and set according to actual requirements, including but not limited to 1:1, 1:2, 1:3, and so on.
Referring to fig. 1 and 2, in one embodiment, the distance between the top edge and the bottom edge of the first transparent plate 11 is L, and the distance between the center point of the first gap 17 and the top edge of the first transparent plate 11 is P, where 1/6L is equal to or less than P and equal to or less than 1/3L. Thus, when the distance P is set in this range, it has been found through a lot of experimental studies that the ball drop position is generally at a position of about 1/2L from the top edge of the first light-transmitting plate 11, since 1/6 L.ltoreq.P.ltoreq.1/3L, the distance between the first gap 17 and the ball drop position is about 1/6L to 1/3L, thereby enabling improvement of safety.
In one embodiment, the thickness of the first adhesive layer 13 is D1 and the thickness of the second adhesive layer 14 is D2; wherein D1 is more than or equal to 0.3mm and less than or equal to 0.9mm, D2 is more than or equal to 0.3mm and less than or equal to 0.9mm. Thus, when the sizes of D1 and D2 are set in this range, the thickness is sufficiently large, the laminated glass 10 is not easily broken down by foreign matter, the safety is high, and when the sizes of D1 and D2 are increased, the breakdown resistance is enhanced; in addition, the thickness is not so large that the design requirements are not met when the thickness of the laminated glass 10 is too large.
In one embodiment, 0.7 mm.ltoreq.D1.ltoreq.0.8 mm. Specifically, D1 includes, but is not limited to, any number set to 0.7mm, 0.72mm, 0.75mm, 0.76mm, 0.78mm, 0.8mm, etc., but also less than 0.7mm, and greater than 0.8mm, for example, set to 0.3mm, 0.35mm, 0.38mm, 0.4mm, 0.5mm, 0.6mm, 0.65mm, etc.
In one embodiment, 0.7 mm.ltoreq.D2.ltoreq.0.8 mm. Specifically, D2 includes, but is not limited to, any number set to 0.7mm, 0.72mm, 0.75mm, 0.76mm, 0.78mm, 0.8mm, etc., but also less than 0.7mm, and greater than 0.8mm, for example, set to 0.3mm, 0.35mm, 0.38mm, 0.4mm, 0.5mm, 0.6mm, 0.65mm, etc.
In one embodiment, the filler layer 16 includes a first filler layer 161 positioned below the functional layer 15, i.e., the first filler layer 161 is in the field of view of the driver, i.e., in the lower region 102 of the laminated glass 10. The top side of the first filling layer 161 and the bottom side of the functional layer 15 are provided with a first gap 17, and the first gap 17 is S. The first gap 17 formed between the top edge of the first filling layer 161 and the bottom edge of the functional layer 15 is located at a safe position, i.e. the puncture resistance needs to be considered. As the size S of the first gap 17 is larger, the first gap 17 between the top edge of the first filling layer 161 and the bottom edge of the functional layer 15 is weakened in breakdown resistance.
Wherein 0<S is less than or equal to 3mm, specifically, S is set to be 0 to 1mm, or 1mm to 2mm, or 2mm to 3mm, for example, through a great deal of researches, the laminated glass 10 has strong puncture resistance, meets the national standard ball falling requirement, is not broken down by balls, and in addition, bubbles are not generated basically at the splicing position of the functional layer 15 and the filling layer 16. In addition, as the size S of the first gap 17 is smaller, the puncture resistance is stronger.
Of course, as some alternatives, the size S of the first gap 17 is greater than 3mm, if D1 and D2 are smaller, it will be possible that the laminated glass 10 cannot meet the national standard ball drop requirement, and bubbles are generated at the splicing position of the functional layer 15 and the filling layer 16; if both D1 and D2 are set to be larger, for example, 0.7mm to 0.8mm, a great deal of researches show that the laminated glass 10 has strong puncture resistance, meets the national standard ball drop requirement, is not broken down by the balls, but has obvious bubble problem at the first gap 17.
Referring to FIG. 2, in one embodiment, the thickness of the filling layer 16 is the same as the thickness of the functional layer 15, and the thickness of the functional layer 15 is set to D3, wherein 0.3 mm.ltoreq.D3.ltoreq.0.5 mm. Alternatively, D3 includes, but is not limited to, being set to 0.3mm, 0.35mm, 0.38mm, 0.4mm, 0.45mm, 0.5mm, and the like. Of course, any value smaller than 0.3mm and larger than 0.5mm can be set according to actual requirements. In addition, specifically, h=d1+d2+d3. That is, the size of H is determined by the regulation and control of D1, D2 and D3, and the size of H can be correspondingly regulated and controlled by flexibly regulating and selecting D1, D2 and D3.
Referring to FIG. 2, in one embodiment, the thickness of the first transparent plate 11 is D4, and D4 is 1.9 mm.ltoreq.D4.ltoreq.2.3 mm. The thickness of the second light-transmitting plate 12 is set to D5, and D5 is 1.9 mm.ltoreq.D5.ltoreq.2.3 mm. Specifically, the size of D4 includes, but is not limited to, 1.9mm, 2mm, 2.1mm, 2.2mm, 2.3mm, etc., although any number set to less than 1.9mm and greater than 2.3mm is also possible. Similarly, the size of D5 includes, but is not limited to, 1.9mm, 2mm, 2.1mm, 2.2mm, 2.3mm, etc., although any number less than 1.9mm and greater than 2.3mm is contemplated. Wherein, both D4 and D5 can be the same or different, and can be flexibly adjusted and set according to actual demands.
Referring to fig. 2, in one embodiment, the filler layer 16 further includes a second filler layer 162 over the functional layer 15. Wherein the thickness of the second filling layer 162 is consistent with the thickness of the first filling layer 161. In this way, the thicknesses of the second filling layer 162, the first filling layer 161 and the functional layer 15 are the same, and the combination stability is better.
Note that, the lower part of the first filling layer 161 located below the functional layer 15 means that the first filling layer 161 is located below the functional layer 15 when the laminated glass 10 is mounted on the vehicle body in a normal posture. Similarly, the upper of the second filler layer 162 located above the functional layer 15 means that the second filler layer 162 is located above the functional layer 15 when the laminated glass 10 is mounted on the vehicle body in a normal posture.
Referring to FIG. 2 again, in one embodiment, D1 is greater than or equal to 0.38mm, D2 is greater than or equal to 0.76mm, S is greater than or equal to 0< 1mm, S+H is greater than or equal to 1.5mm, and through a plurality of tests, it is found that the requirements of the ball falling test of the regulations are met, the laminated glass is ensured not to break down, and no bubble problem exists at the first gap.
Referring to fig. 2, in one embodiment, the second adhesive layer 14 includes a third adhesive layer 141 and a fourth adhesive layer 142 that are disposed on the same layer and have a second gap 143. The second gap 143 is positioned in correspondence with the first gap 17. The third adhesive layer 141 is connected to the first filling layer 161, and the fourth adhesive layer 142 is connected to the functional layer 15.
Referring to fig. 2, in one embodiment, the third adhesive layer 141 and the fourth adhesive layer 142 have the same thickness, so that the assembly and connection have better stability. Of course, the thicknesses of the third adhesive layer 141 and the fourth adhesive layer 142 may be set to be different.
Referring to fig. 3, fig. 3 shows a cross-sectional block diagram of another embodiment of fig. 1 at A-A. In one embodiment, the third adhesive layer 141 is of unitary construction with the first filler layer 161. Specifically, the third adhesive layer 141 and the first filling layer 161 include, but are not limited to, extrusion molding, compression molding, milling, and the like, and specifically can be flexibly adjusted and set according to actual requirements. Specifically, the thickness of the structure after the third adhesive layer 141 and the first filling layer 161 are combined is equal to the thickness of the fourth adhesive layer 142 and the functional layer 15, so that the flatness and stability of the combined structure can be ensured.

In one embodiment, the first adhesive layer 13, the second adhesive layer 14, and the filler layer 16 are the same material.
In one embodiment, the materials of the first adhesive layer 13, the second adhesive layer 14, and the filler layer 16 each include, but are not limited to, materials configured as PVB (polyvinyl butyral ) materials, PU (polyurethane) materials, or EVA (ethylene-vinyl acetate copolymer, ethylene-vinyl acetate) materials.
In one embodiment, the material of the functional layer 15 includes, but is not limited to, a material provided as PDLC (polymer dispersed liquid crystal ) material, LC (liquid crystal) material, EC (Electrochromic) material, or SPD (Suspended Particle Device, suspended particle) material.
In order to make the relation between the thickness D1 of the first adhesive layer 13, the thickness D2 of the second adhesive layer 14, and the selection of the first gap 17S and the puncture resistance of the laminated glass 10 more clearly show, a specific experimental table is shown below for reference, and each data unit in the table is mm.
In one embodiment, a vehicle, including but not limited to an automobile, car, jeep, bus, etc., includes the laminated glass 10 of any of the above embodiments.
The vehicle has the advantages that the functional layer 15 with the dimming function is integrated, so that the light intensity can be adjusted automatically, and when the light outside the vehicle is strong, the color of the functional layer 15 is darkened, and the light blocking effect is realized. In addition, since the first adhesive layer 13 and the second adhesive layer 14 are respectively connected to the opposite sides of the functional layer 15 and the filler layer 16, the structural strength can be improved, the laminated glass 10 is not easily broken down by foreign substances, and the safety can be improved. Wherein, the distance between the two side surfaces of the first adhesive layer and the second adhesive layer which are opposite to each other is H. Furthermore, the filling layer comprises a first filling layer located below the functional layer. The top edge of the first filling layer and the bottom edge of the functional layer are provided with a first gap, and the size of the first gap is S. Wherein 0<S is less than or equal to 3mm,1mm is less than or equal to H is less than or equal to 2mm, and S+H is less than or equal to 1.5mm and less than or equal to 4.5mm.
Furthermore, the terms "first," "second," and the like, if any, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In the description of the present application, the terms "plurality" and "a plurality" if any, mean at least two, such as two, three, etc., unless specifically defined otherwise.
In this application, unless explicitly stated and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly. For example, the two parts can be fixedly connected, detachably connected or integrated; can be mechanically or electrically connected; either directly or indirectly, through intermediaries, or both, may be in communication with each other or in interaction with each other, unless expressly defined otherwise. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.
In this application, unless expressly stated or limited otherwise, the meaning of a first feature being "on" or "off" a second feature, and the like, is that the first and second features are either in direct contact or in indirect contact through an intervening medium. Moreover, a first feature being "above," "over" and "on" a second feature may be a first feature being directly above or obliquely above the second feature, or simply indicating that the first feature is level higher than the second feature. The first feature being "under", "below" and "beneath" the second feature may be the first feature being directly under or obliquely below the second feature, or simply indicating that the first feature is less level than the second feature.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
