Description

Technical Field

[0001] The invention relates to the technical field of glass manufacturing, and in particular to a vehicle door window glass and a vehicle. Background Art

[0002] For vehicles, there are some emergency scenarios where windows need to be broken for escape.

[0003] At present, the glass used in car doors mainly includes tempered glass and laminated glass. Taking the door window glass of the combination door of new energy vehicles as an example, it usually adopts full tempered glass or semi-tempered laminated glass.

[0004] For fully tempered glass, its surface stress is large (≥90MPa), the fragments are small and numerous (the standard requires 40 to 400 fragments within the range of 25mm*25mm, and the length of the fragments is less than 100mm). Once the glass is broken, it is easy to enter or escape from the car. However, due to the high surface stress and high impact resistance, it is difficult to break, and special pointed / sharp metals are needed to break the glass.

[0005] For semi-tempered laminated glass, its surface stress is (≥30MPa), the fragments are in the shape of long strips, the length exceeds 100mm, and the number of fragments within the range of 25mm*25mm is less than 40. This kind of laminated glass has low stress and is easy to break. However, because of the adhesion of the middle layer of PVB, even after being broken, the fragments will still adhere to the PVB and maintain their original shape. The glass is still stuck in the sealing groove of the car door, making it difficult to enter the car or drill out from the car. The glass needs to be removed completely to prevent the long and thin strips of fragments from causing harm to escapees or rescuers.

[0006] In addition, there is a special tempered laminated glass in the existing car door glass, which combines the above two fragment states. The outer piece is fully tempered granular, and the inner piece is made of tempered steel fragments in the shape of thin strips. It is not easy to be broken, but it is also difficult for escapees or rescuers to pass quickly.

[0007] If breaking the window is difficult, it will make escape / rescue difficult if the door handle fails. Especially for new energy vehicles, the vehicle battery will be squeezed, deformed and exploded, usually starting to spontaneously combust within 1 to 2 minutes, and the escape time is very limited.

[0008] For this reason, it is necessary to propose a car door window glass to solve the above problems. Summary of the invention

[0053] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0054] The present invention provides a vehicle door window glass and a vehicle, which can realize rapid window breaking to form a safe exit in a short time, and is beneficial to improving the escape safety performance of the vehicle.

[0055] Please refer to Figures 1 to 9 In the embodiment of the present application specification, a vehicle door window glass is provided, which may include: a glass body 100, at least a part of the glass body 100 is a weakened area 110, the weakened area 110 is provided with a weakening structure, and the weakened area 110 is arranged around the end edge of the glass body 100. When a predetermined force is applied to the weakened area 110, the glass body 100 can be broken at the position of the weakened area 110 within a predetermined time and form a safe exit.

[0056] In the embodiment of the present application, the vehicle door window glass may include a glass body 100. The specific types of the glass body 100 may include tempered glass, laminated glass, and other glass forms that can be applied to vehicle door windows. In the embodiment of the present application, the glass body 100 is mainly illustrated by taking tempered glass and laminated glass as examples.

[0057] Of course, the specific configuration of the glass body 100 may be other methods and is not limited to the above description. Technicians in the relevant field may make other changes inspired by the technical essence of this application. However, as long as the functions and effects achieved are the same or similar to those of this application, they should be included in the protection scope of this application.

[0058] In this embodiment, at least a part of the glass body 100 is a weakened area 110, the weakened area 110 is provided with a weakening structure, and the weakened area 110 is arranged around the edge of the glass body 100. When a predetermined force is applied to the weakened area 110, the glass body 100 can be formed at the position of the weakened area 110 to achieve window breaking within a predetermined time.

[0059] Wherein, the predetermined time is within 1 minute. When the vehicle door window glass provided by the present application is used in a vehicle, when an emergency situation requires breaking a window, the time for the vehicle door window glass to be broken to form a safe exit is within 1 minute, thereby better meeting the escape safety performance requirements of various vehicle types.

[0060] Among them, the specific size of the emergency exit needs to meet certain requirements so that the driver and passengers in the car can evacuate in time. Specifically, the minimum size of the emergency exit is 520 mm × 265 mm, which can meet the escape needs. In the implementation of the present application, when the door window glass is used in the vehicle, the specific size can be 700 mm × 600 mm. Of course, the specific size of the emergency exit can be adaptively adjusted according to the size of the door window glass, etc., and the present application does not make a unique numerical limitation on it.

[0061] The present application will be described in detail below in conjunction with specific implementation methods and drawings.

[0062] Please refer to Figures 1 to 5 In some embodiments, the glass body 100 may include tempered glass, and the weakening structure is disposed in at least a portion of the middle and / or surface of the tempered glass along the thickness direction of the glass body 100 .

[0063] In this embodiment, the glass body 100 may include tempered glass, and the surface compressive stress of the tempered glass is greater than or equal to 90MPA. The thickness of the tempered glass may be between 2.5 mm and 5.0 mm. The thickness of the tempered glass may vary according to the specific scenario in which it is currently applied, the performance parameters of the glass in the specific scenario, and other requirements. In the embodiment of the present application, the situation that the thickness of the tempered glass is greater than 5 mm or less than 2.5 mm is not excluded. For example, the thickness of the tempered glass may include any one of the following: 2.85mm / 3.15mm / 3.5mm / 3.85mm / 4.85mm. The tempered glass may specifically be fully tempered glass. Of course, the specific form and thickness of the tempered glass may be adaptively adjusted according to the actual application scenario, and the present application does not make the sole limitation here.

[0064] In this embodiment, the glass body 100 may be provided in the middle (eg Figure 3 as shown) or inner surface 111 (as shown Figure 4 As shown), the outer surface 112 (as Figure 5 Some defects are introduced (as shown) to form a weakening structure, thereby reducing the strength of the glass body 100 at the weakened area 110 where the weakening structure is provided, so that when this position is subsequently struck, the glass can break quickly to form a safe exit, thereby meeting the safety performance requirements for short-time escape.

[0065] Specifically, the position, size, geometry, and depth of the defects used to form the weakening structure may vary according to different glass manufacturing processes and special requirements, and the present application does not make specific limitations here. Figure 2 As shown, the weakened structure may include: a plurality of break points 101 arranged at intervals.

[0066] In this embodiment, the area enclosed by the outer edge contour corresponding to the plurality of intervally arranged breaking points 101 is the weakened area 110 , and the specific size, shape, etc. of the weakened area 110 are not limited solely by this application.

[0067] In one embodiment, the weakened area 110 is disposed close to a door frame on which the glass body 100 is installed. Specifically, the door frame may be a frame structure formed on a door of a vehicle for installing glass.

[0068] In this embodiment, the weakened area 110 is arranged close to the door frame where the glass body 100 is installed, that is, the weakened area 110 is arranged close to the edge of the glass body 100 as a whole. When the weakened area 110 is arranged close to the door frame where the glass body 100 is installed, the deformation of the glass body 100 is relatively small when it is impacted by external force (such as smashing the window), and the glass body 100 is more likely to be broken. On the contrary, if the weakened area 110 is arranged far away from the door frame, such as the middle area, the deformation of the glass body 100 will be relatively large when it is impacted by external force (smashing the window), and the deformation will absorb energy, so the glass body 100 is not easy to be broken.

[0069] like Figure 1 As shown, further, the weakened area 110 can be set at the corner 102 of the glass body 100, that is, close to the corner of the glass body 100. Specifically, the edge of the glass body 100 includes a plurality of contour lines, and two adjacent contour lines intersect to form an intersection, and the corner 102 is a region close to the intersection. When the glass body 100 is assembled with the door frame, the corner 102 can be located in the window of the door frame, that is, it will not be blocked by the door frame.

[0070] For example, the number of the corners may be four, and the weakened areas 110 may be formed in the four corners, so that when an emergency situation requires breaking a window, the window can be quickly broken by tapping any one of the four corners.

[0071] When the weakened area 110 is close to the door frame, specifically the corner where two frames meet, the deformation of the glass body 100 will be smaller because the door frame applies a supporting force to the glass body 100. The smaller the deformation, the greater the corresponding energy. Once the glass body 100 cannot withstand the impact energy, it will be more likely to break.

[0072] Among them, since the glass body 100 needs to be assembled with the door frame, the distance between the weakened zone 110 and the end edge of the glass body 100 is greater than or equal to 5 mm. The distance between the weakened zone 110 and the end edge of the glass body 100 is a reserved assembly distance. When the door window glass has different assembly dimensions with the door frame to which it is applied, the size that needs to be reserved between the weakened zone 110 and the end edge of the glass body 100 is different. Overall, it is at least necessary to ensure that after the glass body 100 is assembled with the door frame, the weakened zone 110 is located outside the door frame.

[0073] In one embodiment, the weakened structure may be a defect introduced by a laser.

[0074] When the weakening structure is introduced by laser, it can be introduced by laser before bending or after bending. Specifically, the present application does not make any specific limitation here.

[0075] When a defect is introduced by laser, the shape, structure and position of the defect can be finely controlled. Specifically, the weakened structure can be a trademark or a predetermined pattern formed on the surface of the glass body 100 by laser. In this way, both aesthetics and practicality can be taken into account.

[0076] Of course, in the implementation manner of the present application, defects can also be introduced by other means, such as physical weakening, chemical weakening, etc. Relatively speaking, when a weakened structure is formed by laser, it has high controllability and is convenient for forming a weakened structure with a predetermined shape and structure at a specified position with high precision.

[0077] Please refer to Figures 6 to 9 In some other embodiments, the glass body 100 includes laminated glass, and the laminated glass includes an inner glass 200, an adhesive layer 300 and an outer glass 400 arranged in sequence along the thickness direction, and the weakening structure includes: a first defect set in at least a portion of the middle and / or surface of the inner glass 200, a second defect set in at least a portion of the middle and / or surface of the outer glass 400; a third defect set on the adhesive layer 300; the positions where the first defect and the second defect are set are at least partially opposite to each other to form the weakened zone 110, and the third defect is located in the weakened zone 110.

[0078] The glass body 100 may be a laminated glass, which may include an inner glass 200, an adhesive layer 300 and an outer glass 400 arranged in sequence in the thickness direction. The thickness of the inner glass 200 is between 0.7 mm and 2.5 mm, for example, the thickness of the inner glass 200 may include any one of the following: 2.1 / 1.6 / 1.4 / 1.1 / 0.7 mm. The thickness of the outer glass 400 may be between 1.6 mm and 5 mm, for example, the thickness of the outer glass 400 may include any one of the following: 3.5 / 3.2 / 2.85 / 2.1 / 1.6 / 1.4 / 1.1 / 0.7 mm. The thickness of the inner glass 200 may be the same as or different from the thickness of the outer glass 400. The adhesive layer 300 may be a transparent thermoplastic polymer film or a colored thermoplastic polymer film, and the thickness of the adhesive layer 300 may be 0.38 mm to 2.28 mm. For example, the thickness of the adhesive layer 300 can be but is not limited to 0.38mm, or 0.76mm, or 1.14mm, or 1.52mm, or 1.9mm, or 2.28mm, or other values ​​between 0.38mm and 2.28mm. The material of the thermoplastic polymer film can be selected from at least one of polyvinyl butyral (PVB), polyurethane (PU), ethylene-vinyl acetate copolymer (EVA) and ionomer (SGP). In an embodiment of the present application, the material of the adhesive layer 300 is mainly illustrated by taking polyvinyl butyral (PVB) as an example, and when the adhesive layer 300 adopts other materials, the present application can be adaptively referred to.

[0079] In this embodiment, a weakened area 110 may be provided on the inner glass 200 and the outer glass 400, and a weakened structure may also be introduced on the bonding layer 300. Specifically, the weakened structure may include: a first defect provided in at least a portion of the middle and / or surface of the inner glass 200, a second defect provided in at least a portion of the middle and / or surface of the outer glass 400; a third defect provided on the bonding layer 300; the positions where the first defect and the second defect are provided are at least partially opposite to each other to form the weakened area 110, and the third defect is located in the weakened area 110.

[0080] The weakened area 110 may be located in the water cut area 500, and the water cut area 500 may be an area enclosed by a 10 mm upward and downward offset based on the water cut center line 501. Specifically, the weakened area 110 of the inner glass 200 may be located in the water cut area 500, and the weakened area 110 of the outer glass 400 may be located in the water cut area 500.

[0081] For laminated glass, since an adhesive layer 300 is disposed in the middle thereof, even after the glass is broken, the glass fragments are still adhered to the adhesive layer 300 and may still be difficult to be bent, thereby affecting the time for forming a safe exit.

[0082] When it is necessary to break a window, most people will apply a push / pull force to the middle area of ​​the door glass. The water cut position is a relatively effective stress point for breaking the door glass. When the weakened area 110 is set in the water cut area 500, it is less difficult to bend the glass there subsequently, which can help shorten the time to form a safe exit. In addition, after the glass is bent at the water cut position, the window for escape is also the largest, which can ensure that the size of the safe exit is large enough.

[0083] Of course, for the definition of the above-mentioned water cut area 500, the definition of its boundaries may vary slightly depending on the size, structure, etc. of the door frame in which the laminated glass is specifically installed. Based on the contents disclosed in this application, those skilled in the art can make adaptive adjustments based on the above-defined boundary range according to different specific application scenarios.

[0084] For the inner glass 200 and the outer glass 400, the method of introducing defects on the glass can refer to the specific description of the tempered glass. For example, for the inner glass 200 or the outer glass 400, some defects can also be introduced in the middle or on the inner surface 111 / outer surface 112 of the glass, wherein the position, size, geometric shape, and depth of the defects can adapt to different manufacturing processes and special requirements of the glass. The defect introduction method can also be the laser method, that is, the first defect, the second defect, and the third defect can be introduced by laser.

[0085] Specifically, the second defect of the outer glass 400 may include a plurality of spaced-apart break points 101. The specific arrangement of the break points 101 may refer to the textual description of the above-mentioned tempered glass implementation method and the attached drawings. Figures 3 to 5 .

[0086] Specifically, the first defect of the inner glass 200 may include: a plurality of break points 101 arranged at intervals and / or a plurality of openings with a predetermined diameter.

[0087] The first defect of the inner glass 200 may include a plurality of spaced break points 101. The specific arrangement of the break points 101 may refer to the textual description and the attached description of the above-mentioned tempered glass implementation. Figures 3 to 5 .

[0088] In addition, the specific form of the first defect of the inner glass 200 can also be other forms. For example, the first defect of the inner glass 200 can include a plurality of openings with a predetermined diameter. The openings can be through holes or blind holes. Since the inner glass 200 is close to the side of the vehicle interior, a series of through holes or blind holes with small diameters can be set on the glass, thereby reducing the strength of the inner glass 200 at the position where the openings are set, that is, forming the first defect, and at the same time, it will not have a negative impact on the appearance or reliability of the entire glass.

[0089] See also Figure 7 and Figure 8 In one embodiment, the third defect may include a continuous or discontinuous preset fracture line 301 , and the preset fracture line 301 covers the water cutting center line 501 .

[0090] In this embodiment, if Figure 7 As shown, the adhesive layer 300 can be provided with a continuous preset fracture line 301 at the water cutting position by laser or other methods. The continuous fracture line 301 can be a whole strip-shaped crack extending longitudinally along the water cutting center line 501 as a whole.

[0091] Or, if Figure 8 As shown, the adhesive layer 300 can be provided with a plurality of preset fracture lines 301 at intervals at the water cutting position by laser or other methods. The plurality of preset fracture lines 301 at intervals can also be arranged longitudinally and at intervals along the water cutting center line 501 .

[0092] In general, the end of the fracture line 301 is spaced a predetermined distance from the edge of the laminated glass, thereby preventing external water vapor from entering the laminated glass due to the fracture line 301. Specifically, the end of the preset fracture line 301 is at least 5 mm away from the edge of the glass body 100, thereby reliably blocking external water vapor and preventing the adhesive layer 300 of the laminated glass from being delaminated and bubbling due to the influence of the external environment.

[0093] For the inner glass 200 or the outer glass 400, defects thereon may be introduced before bending or after bending.

[0094] As for the third defect of the adhesive layer 300, if it is introduced before lamination, during the lamination process, due to the action of high temperature and high pressure, the adhesive layer 300 will gradually melt, so that the introduced fracture line 301 will merge again. Therefore, in order to ensure that the fracture line 301 is not affected by high temperature and high pressure and thus fails, it is necessary to introduce the fracture line 301 after the laminated glass is laid.

[0095] In order to verify the escape safety performance of the vehicle door window glass provided in the embodiment of the present application, the inventor conducted the following comparative experiment. The experimental steps are as follows:

[0096] Simulate using a safety hammer to hit the glass from inside the car, break the glass, and then push the glass outward to form a safe exit; record the escape time from breaking the window from inside the car to forming a safe exit.

[0097] Table 1

[0098]

[0099] Please refer to Table 1. Through the above experimental verification, it can also be fully proved that:

[0100] The vehicle door window glass provided in the embodiment of the present application, by providing a weakened area 110 with a weakened structure, makes it easier to break the glass in the weakened area 110, and quickly break the window to form a safe exit in a short time, thereby effectively shortening the escape time. Specifically, the escape time can be shortened from more than 2 minutes to less than 1 minute, about 40 seconds. In particular, for the laminated glass provided with an adhesive layer 300, a weakened area 110 and a preset fracture line 301 are provided at the water cut position, so that the glass is easier to be bent, thereby forming a safe exit with a large enough area, which is beneficial to improving the escape safety performance of the vehicle.

[0101] A vehicle is also provided in an embodiment of the present application, and the vehicle includes the above-mentioned door and window glass. The vehicle can achieve the technical effect achieved by the above-mentioned door and window glass embodiment by arranging the above-mentioned door and window glass. For details, please refer to the specific description of the above-mentioned embodiment, and the present application will not repeat them here.

[0102] The vehicle comprises a vehicle body, the vehicle body has a door frame for installing glass, and the door window glass described in the above embodiment is installed on the door frame.

[0103] The vehicle door and window glass provided in the embodiments of the present application can be applied to doors and windows of various vehicles, for example, can be applied to rail vehicles, new energy vehicles, etc.

[0104] For example, in the case of current new energy vehicles, in order to reduce wind resistance, enhance the vehicle's appearance and sense of technology, and make the vehicle simple and beautiful as a whole, the handle is designed to be a hidden structure. According to calculations, a single hidden door handle can reduce wind resistance by 0.003Cd, and four door handles can reduce a total of 0.012Cd. For every 0.01Cd reduction in the drag coefficient of a pure electric vehicle, the range per 100 kilometers can be increased by more than five kilometers.

[0105] Although the design of invisible door handles can improve the overall aesthetics and aerodynamic performance of the vehicle, it also poses some safety risks, including:

[0106] 1. Difficulty in escaping: In an emergency, the vehicle lacks obvious signs or visibility (especially some models without door handles, models with B / C pillar NFC, fingerprint or button switches), which may make it take longer for passengers to successfully open the door;

[0107] 2. Difficult or unfamiliar operation: Some invisible door handle designs may require specific operation methods or greater force to open, which may make it difficult for some passengers to quickly open the door in an emergency;

[0108] 3. Technical failure: Invisible door handles usually rely on electronic or mechanical systems to open. If these systems fail or lose power, passengers may be unable to open the door;

[0109] 4. Safety of children and elderly passengers: Children or elderly passengers may not be able to effectively operate invisible door handles due to lack of physical strength or technical difficulties, increasing safety risks in emergency situations; some cars are equipped with child locks, making it impossible to open the door from the inside.

[0110] During the use of the vehicle, for example, when a child is trapped in the car and the door cannot be opened from the inside, it is necessary to break the window. If breaking the window is difficult, it will also cause difficulty in escape / rescue if the door handle fails. Especially for new energy vehicles, the vehicle battery will start to spontaneously combust within 1-2 minutes if it is squeezed, deformed and exploded, and the escape time is very limited. The use of the door and window glass provided in this application can shorten the time for the glass to form a safe exit to less than 1 minute, thereby better meeting such scenarios with strict requirements on escape time.

[0111] The above are only a few embodiments of the present invention. Although the embodiments disclosed by the present invention are as above, the contents are only embodiments adopted for facilitating the understanding of the present invention and are not used to limit the present invention. Any technician in the technical field to which the present invention belongs can make any modification and change in the form and details of the embodiments without departing from the spirit and scope disclosed by the present invention, but the patent protection scope of the present invention shall still be subject to the scope defined by the attached claims.
