Detailed Description

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

The present invention will be described in detail below with reference to fig. 1 to 4 in conjunction with examples.

Referring to fig. 1 to 3, a laminated vehicle door glass 1000 according to an embodiment of the present invention may be used as a window glass of a vehicle 2000, for wind shielding, noise reduction, and rain insulation, so that a whole vehicle is in a relatively sealed structure, and may be used at any position of the window glass where the whole vehicle needs to be lifted according to requirements.

As shown in fig. 1 and 2, a laminated glass 1000 for a vehicle door according to an embodiment of the present invention includes: outer layer glass 100, inner layer glass 200, and intermediate layer 300.

As shown in fig. 3, the outer layer glass 100 has a first rounded corner 110, where the first rounded corner 110 is a passivation treatment applied to the edge of the outer layer glass 100 to prevent the edge of the outer layer glass 100 from being too sharp.

As shown in fig. 1 and 3, the inner layer glass 200 is stacked on one side of the outer layer glass 100, and the thickness of the inner layer glass 200 is different from that of the outer layer glass 100; the edge of the inner glass 200 is set back with respect to the edge of the outer glass 100, that is, the inner glass 200 and the outer glass 100 stacked together have different thicknesses; the edges between the inner 200 and outer 100 sheets of glass are misaligned and staggered to provide a certain stack difference.

As shown in fig. 3, the inner layer of glass 200 has a second rounded corner 210. Likewise, the second rounded corner 210 is a passivation treatment applied to the edge of the inner layer of glass 200, so that the inner layer of glass 200 is more secure, prevents other environmental elements from being cut, and is convenient for installation. Further, the radius of the second rounded corner 210 is smaller than the radius of the first rounded corner 110, so that the edge of the inner layer glass 200 is sharper relative to the edge of the outer layer glass 100.

Further, in order to achieve the connection of the outer layer glass 100 and the inner layer glass 200 and the functionality of the laminated door glass 1000, as shown in fig. 2 and 3, the present invention provides that an intermediate layer 300 is connected between the outer layer glass 100 and the inner layer glass 200.

It can be known from the above structure that, in the vehicle door laminated glass 1000 according to the embodiment of the present invention, by designing multiple layers of glass, the connection between the layers of glass is tight, and the thicknesses of the inner layer glass 200 and the outer layer glass 100 are different, so that the whole glass has the advantages of high strength, high rigidity, more stable structure, and difficulty in damage.

Since the radius of the second rounded corner 210 of the inner glass 200 of the present invention is small, the edge of the inner glass 200 is sharper; the radius of the first rounded corner 110 of the outer glass 100 is large, so that the edge of the outer glass 100 is more blunted, and the inner glass 200 is set back so that the sharp edge of the inner glass 200 is spaced from the edge of the blunted outer glass 100. The decorative plate 2100 is usually provided with a glass groove 2200, the edge of the vehicle door laminated glass 1000 is slidably embedded in the glass groove 2200, when the vehicle door laminated glass 1000 is closed and matched with the glass groove 2200, the passivated outer layer glass 100 is preferentially contacted with the glass groove 2200, and the sharp inner layer glass 200 is delayed to be contacted with or not contacted with the glass groove 2200, so that the scraping of the edge of the inner layer glass 200 to the glass groove 2200 is weakened, and the glass groove 2200 is not easily scratched by the inner layer glass 200. Therefore, the laminated glass 1000 for the vehicle door of the present invention not only can seal the glass grooves 2200, but also can effectively reduce the damage of the glass grooves 2200.

Therefore, the laminated glass 1000 for the vehicle door of the invention has the advantages of stable structure, good sealing performance, long service life and excellent comprehensive performance.

Compared with the prior art that laminated glass with the same material thickness is used as the whole piece of toughened glass, the whole piece of toughened glass is complex in manufacturing process, easy to damage and heavy in weight, and the vehicle door laminated glass 1000 is simple to manufacture, not easy to damage during installation, good in rigidity and high in strength.

Compared with the multilayer glass with the parallel edges in the prior art, the problems that the glass grooves 2200 are scratched and the NVH performance of the whole vehicle is reduced due to the fact that the fillet of a certain layer of glass is small and sharp are solved, the laminated glass 1000 of the vehicle door is not prone to scratching the glass grooves 2200, and the glass grooves 2200 are long in service life; in addition, the vehicle door laminated glass 1000 can be in sealing fit with the glass grooves 2200, so that the NVH performance of the whole vehicle is improved.

In some embodiments of the invention, as shown in fig. 1, the horizontal distance 400 between at least one edge of the inner glass 200 and the corresponding edge on the outer glass 100 ranges from 1.2 to 1.5mm (the horizontal distance 400 is shown in fig. 3). Here, the edge may be an edge of the entire vehicle X direction, such as a front side edge of the inner glass 200, which is close to the a pillar of the vehicle 2000; also for example, the rear side edge of the inner pane 200, which is close to the B-pillar of the vehicle 2000; the edge here may also be an edge of the entire vehicle in the Z direction, for example, an upper side edge of the inner layer glass 200, which is close to the vehicle ceiling; and an underside edge of the inner ply of glass 200, for example, which is adjacent to the top surface of the wheel. When the horizontal distance 400 is less than 1.2mm, the inner layer glass 200 of the laminated glass 1000 of the vehicle door is easy to scratch to the glass wool groove 2200; when the horizontal distance 400 is greater than 1.5mm, structural rigidity and strength of the door laminated glass 1000 may be reduced, and sealing may be also not facilitated. Therefore, the range value of the horizontal distance 400 is selected to be within the range of 1.2 to 1.5mm, so that the outer layer glass 100 is directly contacted with the glass groove 2200 when the laminated glass 1000 of the vehicle door is instantly closed, the scraping does not occur or is reduced between the inner layer glass 200 and the glass groove 2200, and the glass groove 2200 is prevented from being damaged; the rigidity and the strength of the vehicle door laminated glass 1000 can be effectively improved, the vehicle door laminated glass 1000 is ensured to form reliable sealing after being matched with the glass grooves 2200, and the NVH performance of the whole vehicle is ensured.

In other examples, the horizontal distance 400 is 1.2mm or 1.3mm, which can be adjusted accordingly according to actual needs.

In some embodiments of the present invention, as shown in fig. 1 and 2, the door laminated glass 1000 has the water tangent 500, the edge of the inner layer glass 200 facing the water tangent 500 does not exceed the water tangent 500, that is, the edge of the inner layer glass 200 on the side extends to the water tangent 500 at the maximum, the inner layer glass 200 is not disposed below the water tangent 500, but only the outer layer glass 100 remains, and the outer layer glass 100 extends beyond the water tangent 500. Thereby make door laminated glass 1000's structure lighter and more handy, save material to conveniently arrange door laminated glass 1000 on the door panel beating, make door laminated glass 1000 can go up and down. It should be noted here that the area below the water cut line 500 is not visible when the window is closed.

The material of the outer layer glass 100 and the inner layer glass 200 may be the same or different.

Optionally, the outer layer glass 100 and the inner layer glass 200 may have an arc surface with a certain curvature, or may be a plane, and may be designed according to actual needs.

In some embodiments of the present invention, the radius of the first rounded corner 110 shown in fig. 3 is not less than half of the first thickness 120, that is, the radius of the first rounded corner 110 is at least 1.75mm, so as to ensure that the outer layer of glass 100 has a sufficiently gentle edge, which does not scratch the glass grooves 2200 when the outer layer of glass 100 contacts the glass grooves 2200 during lifting and lowering, and thus is convenient for installation on the whole vehicle.

Optionally, the radius of the first rounded corner 110 is 1.75 to 2.0mm, and the radius of the first rounded corner 110 is less than 1.75mm, so that the outer layer glass 100 is easy to damage the glass slot 2200 when contacting the glass slot 2200; the first rounded corner 110 is difficult to make when it is greater than 2.0mm, and may form a sharp corner in the middle region of the thickness.

According to the vehicle 2000 of the embodiment of the present invention, since the door laminated glass 1000 according to the above embodiment of the present invention has the above technical effects, and the door laminated glass 1000 has the same advantages as the door laminated glass 1000 described above compared with the prior art, which are not described in detail herein, the vehicle 2000 according to the embodiment of the present invention also has corresponding technical effects, specifically:

in the process of instantaneous lifting of the laminated vehicle door glass 1000, the laminated vehicle door glass will be matched with the glass grooves 2200 and contact with the first lip 2210 and the second lip 2220, and since the outer layer glass 100 preferentially contacts with the first lip 2210, the first lip 2210 will not be scratched; the inner glass 200 is in little or no contact with the first lip 2210, so that the acting force is small, and even if the radius of the second fillet 210 of the inner glass 200 is small, the inner glass 200 is relatively sharp, so that the first lip 2210 is not damaged, and the damage of the glass groove 2200 is effectively reduced. Therefore, the structure of the vehicle 2000 of the invention effectively improves NVH performance and sealing performance when the window is closed.

In addition, the sandwich structure formed by the inner layer glass 200, the outer layer glass 100 and the middle layer 300 greatly improves the stability and rigidity of the whole vehicle glass. The second lip 2220 is in contact with the side surface of the inner pane 200, and can further ensure stability and sealing performance when the window is closed, reduce the rattling of the window glass, and reduce abnormal noise.

In some specific examples, the decorative plate 2100 refers to a B-pillar decorative plate, and the glass groove 2200 is provided on the B-pillar decorative plate, so that when the door laminated glass 1000 is closed, the scraping effect on the glass groove 2200 on the B-pillar decorative plate can be reduced.

In some embodiments of the present invention, when the door laminated glass 1000 is closed, the first lip 2210 abuts against the outer glass 100, and the first lip 2210 is bent toward the second lip 2220 by the outer glass 100. Thus, in these examples, first lip 2210 interacts directly with outer pane 100 to effect sealing of the window, and first rounded corner 110 of outer pane 100 is of a larger radius without scratching first lip 2210. A relatively closed cavity is formed between the first lip 2210 and the second lip 2220 and the inner glass 200, and has a certain sound insulation performance.

Advantageously, the laminated glass 1000 for the vehicle door can be matched with a frameless vehicle door, so that the vision of drivers and passengers is widened, the blind area near the A column is reduced, and the safety, the effective tightness and the excellent NVH performance are ensured.
