Description

Technical Field

[0001] The present application relates to the technical field of automobile glass, and in particular to a sunroof glass, a sunroof assembly and an automobile. Background Art

[0002] In order to obtain a wider view and brighter lighting environment inside the car, more and more models are beginning to use panoramic sunroofs. The main component of a panoramic sunroof is the sunroof glass. Compared with sunroof glass with sunshades, sunroof glass without sunshades is more widely used due to its cost and space advantages.

[0003] However, in actual use, when the car is in a strong light environment, the field of vision of the passengers in the back row will form a straight line of sight with the sunlight obliquely shining into the car through the front end of the sunroof glass, causing discomfort such as glare and other discomfort to the passengers in the back row, affecting their comfort. Summary of the invention

[0004] Based on this, it is necessary to provide a sunroof glass, a sunroof assembly and a car to address the problem of glare and other discomfort caused by sunlight.

[0040] See also Figure 1 , is a skylight glass 100 shown in an embodiment of the present application, which includes a glass structure layer and a light control structure layer 30.

[0041] For example, in this embodiment, the glass structure layer includes an outer glass plate 10 and an inner glass plate 20, and the light control structure layer 30 is stacked between the outer glass plate 10 and the inner glass plate 20. That is, the light control structure layer 30 is installed between the inner glass plate 20 and the outer glass plate 10 as an intermediate layer.

[0042] The outer glass plate 10 and the inner glass plate 20 are generally made of inorganic glass and / or organic glass materials, such as soda-lime glass, borosilicate glass, aluminosilicate glass, polymethacrylate, polycarbonate, etc., and soda-lime glass is preferably used.

[0043] The thickness of the outer glass plate 10 and the inner glass plate 20 are both in the range of 1.6 mm to 6.0 mm, such as 1.6 mm, 1.8 mm, 2.0 mm, 2.1 mm, 2.3 mm, 2.5 mm, 2.7 mm, 3.0 mm, 3.4 mm, 3.7 mm, 4.0 mm, 4.4 mm, 4.8 mm, 5.0 mm, 5.4 mm, 5.8 mm, 6.0 mm, etc. The visible light transmittance is 2% to 90%, such as 2%, 5%, 10%, 30%, 50%, 70%, 90%, etc.

[0044] Alternatively, in other optional embodiments, the outer glass plate 10 and the inner glass plate 20 may also be laminated glass. For example, the laminated glass is composed of an inner glass sheet, an outer glass sheet and an intermediate interlayer. The intermediate interlayer may be a hollow layer or a composite multilayer film structure. When a composite multilayer film structure is used, it may be PDLC (polymer dispersed liquid crystal), EC (Electrochromic-EC), LC (liquid crystal), etc., which have a dimming function and may also have an ambient light function.

[0045] The thickness of the inner glass sheet is 0.7mm~3.0mm, for example, 0.7mm, 1.2mm, 1.8mm, 2.3mm, 2.5mm, 2.7mm, 2.9mm, 3.0mm, etc.; the visible light transmittance is 2%~90%, for example, 2%, 5%, 10%, 30%, 50%, 70%, 90%, etc.

[0046] Based on the above embodiment, the skylight glass 100 also includes a first thermoplastic interlayer 80 and a second thermoplastic interlayer 90. The first thermoplastic interlayer 80 is laminated between the outer glass panel 10 and the light control structure layer 30, and the second thermoplastic interlayer 90 is laminated between the inner glass panel 20 and the light control structure layer 30.

[0047] The first thermoplastic interlayer 80 is in a hot-melt state after heating, and can be used to bond and fix the outer glass plate 10 and the light control structure layer 30. The second thermoplastic interlayer 90 can also be in a hot-melt state after heating, and then used to bond and fix the inner glass plate 20 and the light control structure layer 30, so as to realize the stacking and assembly of the outer glass plate 10, the light control structure layer 30 and the inner glass plate 20 to form the skylight glass 100.

[0048] It should be noted that the first thermoplastic interlayer 80 and the second thermoplastic interlayer 90 may specifically be thermoplastic films, which may be colored or transparent, with a visible light transmittance of 0% to 90%; for example, 1%, 2%, 5%, 10%, 30%, 50%, 70%, 90%, etc.

[0049] When the first thermoplastic interlayer 80 and the second thermoplastic interlayer 90 are used on the skylight glass 100 of the present application, the visible light transmittance is preferably 2% to 10%; and the thickness is 0.38 mm to 1.52 mm.

[0050] Please continue reading Figure 2In the present application, the light control structure layer 30 is arranged on the glass structure layer, and the light control structure layer 30 includes a light control layer 31, and the light control layer 31 includes at least two light blocking parts 31a, and a light-transmitting part 31b is formed between two adjacent light-blocking parts 31a. The light-transmitting part 31b is used to allow non-direct sunlight within a specific incident angle range 40 to pass through, and the light-blocking part 31a is used to block non-direct sunlight outside the specific incident angle range 40.

[0051] Optionally, the thickness of the light control structure layer 30 is greater than 50 μm and less than or equal to 420 μm.

[0052] Optionally, the thickness of the light control layer 31 ranges from 50 μm to 150 μm, for example, 50 μm, 70 μm, 90 μm, 110 μm, 120 μm, 140 μm, 150 μm, and the like.

[0053] Optionally, the light-transmitting portion 31 b is a transparent thermoplastic material, such as TPU, PVB, PVC, etc., and its visible light transmittance is 2% to 90%; for example, 2%, 5%, 10%, 30%, 50%, 70%, 90%, etc.

[0054] Furthermore, the light control structure layer 30 further includes a first protective layer 34 and a second protective layer 35 . The first protective layer 34 is stacked on one side of the light control layer 31 in the thickness direction, and the second protective layer 35 is stacked on the other side of the light control layer 31 in the thickness direction.

[0055] Therefore, the first protective layer 34 and the second protective layer 35 also form an encapsulation protection for the light control layer 31 to prevent the light control structure layer 30 from being damaged when being assembled with the outer glass plate 10 and the inner glass plate 20 .

[0056] For example, the first protective layer 34 and the second protective layer 35 may be made of, but not limited to, PET, PVC, etc.

[0057] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: the sunroof glass 100 of this solution is applied to the sunroof assembly of a car, and the sunroof glass 100 is specifically composed of a glass structure layer and a light control structure layer 30 arranged on the glass structure layer. When the sunroof glass 100 is in a strong light irradiation environment, since a light-transmitting portion 31b is formed between two adjacent light-blocking portions 31a in the light control layer 31, the light-transmitting portion 31b can allow non-direct sunlight within a specific incident angle range 40 to pass through and enter the car, on the one hand This part of indirect sunlight will not directly hit the passengers' eyes, so as not to cause discomfort such as glare and blinding to the passengers. On the other hand, this part of indirect sunlight can be shot into the car through the light-transmitting portion 31b, which can meet the need to create a bright light environment in the car. However, the sunlight that cannot be seen directly outside the specific incident angle range 40 will be blocked by the light-blocking portion 31a, so this part of the sunlight that cannot be seen directly will not be able to directly hit the passengers' eyes, thereby avoiding discomfort such as glare and blinding to the passengers, thereby ensuring the passengers' riding comfort.

[0058] In the present application, the light blocking portion 31 a is made of a light-shielding material and has a width of 5 μm to 50 μm, for example, 5 μm, 8 μm, 10 μm, 15 μm, 20 μm, 25 μm, 40 μm, 50 μm, and the like.

[0059] The visible light transmittance of the light-blocking portion 31a is less than 0.5%. The light-blocking portion 31a can block the sunlight that cannot be seen directly from continuing to propagate.

[0060] The light-shielding material used for the light-blocking portion 31 a may be a dark-colored thermoplastic material, or may be a dark-colored coating, a dark-colored sputtered coating layer, or the like.

[0061] It should be noted that the "not to look directly at the sunlight" mentioned in this application specifically refers to sunlight with a light intensity of 3500LX (lumens) or above. This is because when the light intensity of sunlight reaches or even exceeds 3500LX, it will shine directly into the human eyes, causing the eyes to begin to feel a sense of difficulty in receiving the light, and then produce uncomfortable feelings such as glare and blinding.

[0062] Alternatively, the light blocking portion 31a may conditionally allow sunlight to pass through. For example, the light blocking portion 31a may adjust sunlight with a light intensity of more than 3500 LX to within 3500 LX, thereby avoiding discomfort such as glare and the like to passengers.

[0063] Please continue reading Figure 2In addition, based on any of the above embodiments, two adjacent light-blocking portions 31a are respectively a first light-blocking portion 311a and a second light-blocking portion 312a, and the first light-blocking portion 311a has a first side surface arranged toward the second light-blocking portion 312a, and the first side surface includes a first side edge and a second side edge arranged at intervals along the thickness direction of the light control structure layer 30, for example, the first side edge is above the second side edge.

[0064] The second light blocking portion 312a has a second side surface disposed toward the first light blocking portion 311a, and the second side surface includes a third side edge and a fourth side edge spaced apart along the thickness direction of the light control structure layer 30, for example, the third side edge is above the fourth side edge.

[0065] The line connecting the first side and the fourth side forms a first boundary line 32 , the line connecting the second side and the third side forms a second boundary line 33 , and the angle range defined by the area enclosed by the first boundary line 32 and the second boundary line 33 is a specific incident angle range 40 .

[0066] In this way, the first boundary line 32 and the second boundary line 33 can limit the area where the sunlight forming the conical structure passes through the light-transmitting portion 31b, so that the maximum specific incident angle range 40 can be obtained, so that more indirect sunlight can be emitted into the vehicle from the light-transmitting portion 31b, creating a brighter lighting environment inside the vehicle.

[0067] It should be noted that the first boundary line 32 and the second boundary line 33 are the limit propagation paths for indirect sunlight to pass through the light-transmitting portion 31b; that is, with the intersection of the first boundary line 32 and the second boundary line 33 as the center of rotation, when the first boundary line 32 is rotated counterclockwise at any angle and the second boundary line 33 is rotated clockwise at any angle, the indirect sunlight will be blocked by the light-blocking portion 31a due to its propagation beyond the specific incident angle range 40.

[0068] Please continue reading Figure 2 Specifically, the angle between the first boundary line 32 and the vertical direction of the sunroof glass 100 is θ1, and the range of θ1 is 30°~50°; the angle between the second boundary line 33 and the vertical direction of the sunroof glass 100 is θ2, and the range of θ2 is 30°~50°.

[0069] For example, θ1 and θ2 may also be 30°, 33°, 36°, 40°, 43°, 46°, 49°, 50°, etc. Both θ1 and θ2 are within the specific incident angle range 40 .

[0070] Preferably, in one embodiment, θ1 and θ2 are both equal to 40°.

[0071] Taking into account the fact that most passengers have different heights and different sitting postures in the car, which result in different distances between the eyes and the sunroof glass 100, when θ1 and θ2 are both selected to be equal to 40°, it can ensure that the light-blocking portion 31a effectively blocks the direct sunlight and meets the anti-glare and anti-dazzle needs of different passengers.

[0072] The present application provides the following experimental comparative example when θ1 is equal to 40°, to illustrate that the light-blocking portion 31 a effectively blocks the non-direct sunlight rays outside the specific incident angle range 40°.

[0073]

[0074] See also Figure 4 Considering the main visual angle between the passenger and the sunroof glass 100, the incident angle of the sun's rays that cannot be directly viewed, which will cause discomfort such as glare and blindness, is 40°~80°.

[0075] It can be seen that when θ1 is equal to 40°, the light-blocking portion 31a can effectively block the invisible sunlight, thereby preventing the invisible sunlight from directly hitting the passengers' eyes and causing discomfort.

[0076] Furthermore, the non-direct sunlight rays with an incident angle of 40° to 80° can be blocked by the light blocking portion 31 a and thus cannot be directly projected into the vehicle.

[0077] It should be noted that, in combination with the above table and Figure 2 It can be seen that if θ1 and θ2 are both selected to be 40°, that is, when the specific incident angle range 40 is an angle range of 80°, the indirect sunlight within this angle range (such as sunlight with incident angles of 39°, 35°, 30°, 20°, etc.) can normally pass through the light-transmitting portion 31b and enter the vehicle, while the sunlight that cannot be directly viewed in the extreme propagation path with an incident angle of 40° has been blocked by the light-blocking portion 31a and cannot enter the vehicle. Furthermore, the sunlight with an incident angle greater than 40° beyond the specific incident angle range 40, such as sunlight with incident angles of 50°, 60°, 70° and 80°, are all blocked by the light-blocking portion 31a, thereby avoiding the discomfort caused by the sunlight that cannot be directly viewed directly hitting the eyes of passengers. In this way, the present application can achieve the technical effect that sunlight within the specific incident angle range 40 can normally enter the vehicle and provide the required bright light environment inside the vehicle, while at the same time, sunlight outside the specific incident angle range 40 will be blocked by the blocking part 31a and cannot enter the vehicle, causing direct sunlight to the passengers' eyes and thus causing discomfort.

[0078] In another optional embodiment, if θ1 is selected as 30°, and when the non-direct sunlight with an incident angle of 30° begins to be blocked by the light-blocking portion 31a, the non-direct sunlight with an incident angle of 30° to 80° can be blocked by the light-blocking portion 31a, and thus cannot be directly projected into the vehicle, thereby preventing the non-direct sunlight from directly projecting into the eyes of passengers and causing discomfort. However, at this time, the non-direct sunlight within the specific incident angle range 40° of 0° to 29° can normally pass through the light-transmitting portion 31b and project into the vehicle.

[0079] Similarly, if θ1 is selected as 50°, and the non-direct sunlight with an incident angle of 50° begins to be blocked by the light-blocking portion 31a, then the non-direct sunlight with an incident angle of 50° to 80° can be blocked by the light-blocking portion 31a, and thus cannot be directly projected into the vehicle, thereby preventing the non-direct sunlight from directly projecting into the eyes of passengers and causing discomfort. However, at this time, the non-direct sunlight within the specific incident angle range of 0° to 49° can normally pass through the light-transmitting portion 31b and project into the vehicle.

[0080] It should be noted that TL in the above table specifically refers to the transmittance of visible light, and the experimental test was completed under sunlight conditions with a light intensity of 100,000LX.

[0081] It should be noted that for the transmittance data when the incident angle is 85°, the degree of light scattering of the incident sunlight is different at different incident angles. For example, when the sunlight is close to vertical incidence, the absorbed light scattering is less, so the scattered light will scatter into the car.

[0082] Please continue reading Figure 3 In addition, based on any of the above embodiments, the glass structure layer is provided with a visible area 50, and the glass structure layer has a front end 100a, the visible area 50 includes a first side 51 arranged close to the front end 100a and a second side 52 arranged away from the front end 100a; starting from the first side 51 and extending toward the second side 52, the light control structure layer 30 is distributed in the 1 / 3~2 / 3 area of ​​the visible area 50.

[0083] According to the actual situation, taking the rear passengers as an example, the rear passengers usually only look up at a suitable tilt angle to observe the things outside the car through the sunroof glass 100. At this time, the area of ​​the sunroof glass 100 that the rear passengers can normally observe is 1 / 3 to 2 / 3 of the visible area 50 starting from the first side 51. Therefore, distributing the light control structure layer 30 in the 1 / 3 to 2 / 3 area of ​​the visible area 50 can just meet the need of effectively blocking the sunlight that cannot be directly viewed.

[0084] It is understandable that the remaining area after the light control structure layer 30 is arranged in the visible zone 50 is above the heads of the rear passengers, requiring the passengers to look up at a large angle (for example, more than 70°) and causing discomfort, and sunlight with a light intensity exceeding 3500LX can pass through the light-transmitting portion 31b and directly enter the eyes, causing discomfort. Therefore, the rear passengers usually do not do this, and there is no actual need to install the light control structure layer 30 in the entire visible zone 50.

[0085] Please continue reading Figure 1 and Figure 3 In addition, in another embodiment, the glass structure layer is further provided with a first edge blocking area 60 and a second edge blocking area 70, and the glass structure layer also has a rear end 100b away from the front end 100a, the first edge blocking area 60 is arranged between the front end 100a and the first side 51, and the second edge blocking area 70 is arranged between the rear end 100b and the second side 52. When the skylight glass 100 is installed on the roof, the first edge blocking area 60 and the second edge blocking area 70 can cover the edge interior decoration, thereby ensuring the aesthetics of the skylight glass 100 after installation.

[0086] Based on any of the above embodiments, a silver-based coating layer 11 is provided in the middle of the side of the outer glass plate 10 facing the first thermoplastic interlayer 80, and a first edge blocking layer 12 is provided on both opposite side edges of the side of the outer glass plate 10 facing the first thermoplastic interlayer 80.

[0087] The silver-based coating layer 11 is distributed on most of the side of the outer glass plate 10 facing the first thermoplastic interlayer 80, and plays a good heat insulation role when facing the sun's rays. The first edge shielding layer 12 arranged on both sides is mainly used to shield the interior decoration of the roof edge.

[0088] Furthermore, a TCO (transparent conductive oxide) film layer is provided in the middle of the side of the inner glass plate 20 away from the second thermoplastic interlayer 90 , and a second edge blocking layer 22 is provided on both opposite side edges of the side of the inner glass plate 20 away from the second thermoplastic interlayer 90 .

[0089] The TCO film layer 21 is arranged on most of the side of the inner glass plate 20 away from the second thermoplastic interlayer 90, which can further insulate and preserve heat, help maintain the required temperature environment in the vehicle, and ensure riding comfort. The second edge shielding layer 22 arranged on both side edges is mainly used to shield the interior decoration on the edge of the roof.

[0090] The first edge blocking layer 12 and the second edge blocking layer 22 are stacked and aligned in the thickness direction of the skylight glass 100. A group of first edge blocking layers 12 and second edge blocking layers 22 on one side are allocated to form a first edge blocking area 60, and a group of first edge blocking layers 12 and second edge blocking layers 22 on the other side cooperate to form a second edge blocking area 70.

[0091] For example, the first edge blocking layer 12 and the second edge blocking layer 22 may be made of, but not limited to, ceramic ink.

[0092] In addition to the above, the present application also provides a car, which can be any one of a pure electric car, an extended-range car, a pure fuel-powered car, etc.

[0093] The automobile includes a sunroof assembly, which includes a sunroof glass 100 as described in any of the above embodiments. In addition, the sunroof assembly also includes but is not limited to a sunroof guide rail, a sunroof motor and a glass bracket. Sunroof guide rail: responsible for guiding the glass panel to ensure that the sunroof works smoothly throughout the service life of the vehicle. Sunroof motor: composed of a motor body and a driver, which operates in an automatic controlled manner to avoid oscillation and loss of step when the load suddenly changes. Sunroof glass 100 (with a sealing strip): tempered glass is usually used, which forms uniform small particles without sharp corners after being broken, and is called safety glass. Glass bracket: a bracket for mounting the sunroof glass 100, with a sunroof hole formed on the body, and mounting bolts fixedly connected to the surrounding body frame. These components work together to enable the sunroof to be opened and closed smoothly, while improving the air circulation in the car, increasing the entry of fresh air, broadening the field of vision of the driver and passengers, and meeting the shooting needs of mobile photography and videography.
