[0001] The utility model relates to vehicle glass, in particular to a vehicle glass and a vehicle. Background Art

[0002] With the development of vehicle electrification and intelligentization, users put forward higher requirements for the riding and driving experience of vehicles. At present, in order to obtain a better and broader driving view and good driving pleasure, some vehicles adopt panoramic vehicle glass. However, due to the large area of the panoramic vehicle glass, more external heat penetrates through the panoramic vehicle glass into the vehicle, further leading to an imbalance in the in-vehicle thermal management. Moreover, the increase in heat will also increase the energy consumption of the air conditioner and accelerate the aging of the vehicle interior.

[0003] To solve the above problems, the prior art uses coating (such as a metal layer) on the vehicle glass to play a role in heat insulation and sound insulation. However, due to the coverage of the metal layer, the wireless signal inside the vehicle will be attenuated, affecting the normal use of the vehicle. In addition, the metal layer will also cause the vehicle glass to produce reflection, resulting in the road surface camera being unable to clearly capture the image of the driver inside the vehicle. Summary of the Utility Model

[0004] The technical problems to be solved by the utility model include: providing a vehicle glass and a vehicle, while reducing external energy transfer, reducing the impact on the in-vehicle wireless signal.

[0037] 10. Panoramic windshield; 20. Metal layer; Specific implementation manners

[0038] To describe in detail the technical content, achieved objectives and effects of the present utility model, the following is described in conjunction with the implementation manners and with reference to the drawings.

[0039] Please refer to Figure 1 , for the existing panoramic windshield 10 to play a heat insulation role, a film (metal layer) is usually covered on the panoramic windshield 10. However, due to the coverage of the metal layer 20, the wireless signal inside the vehicle will attenuate, affecting the normal use of the vehicle. In addition, the metal layer 20 will also cause the panoramic windshield 10 to produce reflection, resulting in the road surface camera being unable to clearly capture the image of the driver inside the vehicle.

[0040] Based on this, refer to Figures 2 - 7, a vehicle is proposed, which includes a vehicle glass 1 and a vehicle frame 2; the vehicle glass 1 includes a first region 11 and a second region 12 from top to bottom in the longitudinal direction. The first region 11 includes a barrier function area 111, and the second region 12 includes a safety vision area 121. The barrier function area 111 includes at least one of a heat insulation function layer 16, a sound insulation function layer 17, or a light dimming function layer 18, or any combination thereof; the safety vision area 121 includes a heat insulation blank area. In order to ensure that the face of the driver inside the vehicle can be successfully captured by the road surface camera and ensure that the driver obtains a good vision, the optimal safety vision area 121 should be set according to the national standard "GB 11562".

[0041] It can be understood that by adopting the method of locally setting the barrier function area 121 on the vehicle glass 1, the shielding effect on the wireless signal is reduced. Since most of the heat and noise usually enter the vehicle from the roof, a barrier function area 121 is set in the first region 11 of the vehicle glass 1 close to the sunroof, and at least one functional layer is set in the barrier function area 121, which can block most of the external energy such as heat and noise. And a safety vision area 111 is set in the second region 12 of the vehicle glass 1. On the one hand, it is convenient for the propagation of wireless signals, and on the other hand, it can reduce the occurrence of reflection phenomena, so that the camera can obtain the face information of the people inside the vehicle. The utility model can not only reduce the transmission of heat, noise, etc., but also reduce the impact on the in-vehicle wireless signal.

[0042] In some embodiments, the vehicle glass 1 includes an outer glass plate 14, an inner glass plate 15, and a barrier function area 111; the barrier function area 111 is sandwiched between the inner glass plate 15 and the outer glass plate 14. Optionally, the heat insulation function layer 16 can be a single layer or multiple layers.

[0043] The heat insulation function layer 16 can include materials with conductive properties such as a pure metal film layer, a metal alloy layer, or a metal oxide film layer, or a film layer formed by compounding the above three film layers. Further, the heat insulation function layer 16 is a pure metal film or a metal alloy layer. Preferably, the heat insulation function layer 16 is selected as a silver-plated layer or a low-emissivity metal film layer (i.e., a LOW-E layer), where the LOW-E layer can be prepared from a thin film composed of multiple metals or metal compounds. The heat insulation function layer 16 can also include an anti-ultraviolet layer, and the material of the anti-ultraviolet layer can be at least one of a PVB (polyvinyl butyral) film, an SGP (an ionomer of ethylene and methyl acrylate) film, an EVA (ethylene-vinyl acetate copolymer) film, and a PET (polyethylene terephthalate) film. When two or more film layers are selected as the anti-ultraviolet layer, the different film layers are sequentially stacked to form the anti-ultraviolet layer.

[0044] The dimming functional layer 18 can optimize the heat insulation effect and enable the driver to obtain a good view. Among them, the material of the dimming functional layer 18 can include any one or more of SPD (suspended particles), PDLC (polymer dispersed liquid crystal), or PNLC (polymer network liquid crystal); the sound insulation layer function includes any one or more of thermoplastic resin films such as PVB film, PVC film, saturated polyester resin film, polyurethane resin film, EVA film, or COP (cycloolefin polymer) film.

[0045] In some embodiments, when only one functional layer is provided in the barrier functional area 111, and the heat insulation functional layer 16 or the sound insulation functional layer 17 or the dimming functional layer 18 respectively includes multiple layers of materials, the heat insulation functional layer 16 or the sound insulation functional layer 17 or the dimming functional layer 18 is stacked along the thickness direction of the vehicle glass 1. Therefore, the stacking setting here refers to the stacking setting of multiple film layers in the heat insulation functional layer 16. When multiple functional layers are provided in the barrier functional area 111, the stacking setting here refers to the sequential stacking of multiple functional layers. In addition, only one of the heat insulation functional layer 16, the sound insulation functional layer 17, or the dimming functional layer 18 can be provided in the barrier functional area 111, and this functional layer is formed by only one layer of material.

[0046] In some embodiments, an adhesive layer 19 is further included; the adhesive layer 19 is located between the outer glass sheet 14 and the barrier functional area 111, and / or the adhesive layer 19 is located between the inner glass sheet 15 and the barrier functional area 111; the thickness of the barrier functional area 111 is less than the thickness of the adhesive layer 19. Since multiple functional layers may be compounded in the barrier functional area 111, in order to ensure that the thickness of each part of the vehicle glass 1 is similar, the thickness of the barrier functional area 111 should be less than the thickness of the adhesive layer 19 to cover the thinner adhesive layer 19 in the barrier functional area 111, thereby ensuring the structural stability of the vehicle glass 1.

[0047] In some embodiments, the edges of the sound insulation functional layer 17 or the dimming functional layer 18 are flush with the edge of the heat insulation functional layer 16. When both the sound insulation functional layer 17 and the heat insulation functional layer 16 are provided in the barrier functional area 111, the edges of the sound insulation functional layer 17 and the heat insulation functional layer 16 are flush, or when both the dimming functional layer 18 and the heat insulation functional layer 16 are provided in the barrier functional area 111, the edges of the dimming functional layer 18 and the heat insulation functional layer 16 are flush, so as to avoid obvious boundaries between different functional layers and affect the aesthetics of the vehicle glass 1.

[0048] In some embodiments, the adhesive layer 19 can completely cover the surface of the inner glass sheet 15 or the outer glass sheet 14 to improve the structural stability of the vehicle glass 1. In addition, the adhesive layer 19 can also be a partial area covering the surface of the inner glass sheet 15 or the outer glass sheet 14.

[0049] In some embodiments, an adhesive layer 19 is further included in the first region 11 and the second region 12 , respectively, wherein the thickness of the adhesive layer 19 in the first region 11 is greater than or equal to the thickness of the adhesive layer 19 in the second region 12 . The adhesive layer 19 located in the first area 11 and the adhesive layer 19 located in the second area 12 have different distribution possibilities, as follows: since the first area 11 is also provided with a barrier functional area 111, if the same adhesive layer 19 is provided across the first area 11 and the second area 12, at this time, the thickness of the adhesive layer 19 located in the first area 11 should be less than the thickness of the adhesive layer 19 in the second area 12, that is, the same adhesive layer 19 should form a height difference in the first area 11 and the second area 12, so that the spacing between the inner glass plate 15 and the outer glass plate 14 at various locations is close; or, at least one adhesive layer 19 is provided in the first area 11, and at least two adhesive layers 19 are provided in the second area 12, and the total thickness of the adhesive layer 19 in the first area 11 should always be less than the total thickness of the adhesive layer 19 in the second area 12.

[0050] In some embodiments, the thermal insulation blank area includes a metal film layer blank area, that is, a large area of ​​metal film removal area is set. Specifically, the metal film layer is covered in the thermal insulation blank area, but a metal film removal area is set on the metal film layer, so that the electrical signal communicates with the interior of the vehicle through the metal film removal area, reducing the influence of the metal film layer on the communication. Optionally, the thermal insulation blank area includes a metal film layer blank area and a non-metallic film layer area, that is, a non-metallic film layer area is also set in addition to the metal film removal area, such as setting PVB film, EVA film, PET film and other materials in the non-metallic film layer area, which can not only play a blocking role in the thermal insulation blank area, but also ensure the propagation of electrical signals.

The test instructions are as follows: When measuring, place the sample on the opening of the shielding chamber and press it tightly against the opening of the shielding chamber. The size of the opening of the shielding chamber is 300mm×300mm.

[0078]

[0079] According to the experimental results in the above table, it can be obtained that: among the comparative examples, the electromagnetic wave signals shielded by the vehicle glass without the heat insulation functional layer in Comparative Example 1 are the least, while the electromagnetic signals shielded by the fully coated vehicle glass in Comparative Example 2 are the most, and the electromagnetic signals shielded by the vehicle glass in Example 1 are also less, and its performance is close to that of the vehicle glass in Comparative Example 1. Thus, it can be proved that the partial coating of the vehicle glass in this application significantly weakens the shielding effect on signals, and most signals in this application can communicate smoothly.

[0080] The vehicle glass made in Example 1 of this application and the vehicle glass made in Comparative Example 1 were tested for heat insulation effect using the "ISO9050 Standard Test", and the test results are shown in Table 2 below:
