[0002] This application claims priority to Chinese Patent Application No. 202411270534.6, filed on September 11, 2024, and incorporates by reference the entire disclosure of the aforementioned patent application as part of the present application. TECHNICAL FIELD

[0003] The present application relates to the technical field of glass manufacturing, in particular to a vehicle door window and vehicle. BACKGROUND

[0004] For vehicles, there are some emergency scenarios that require breaking the window to escape.

[0005] The glass currently used on vehicle doors mainly includes tempered glass and laminated glass. Taking the vehicle door window of a combined door of a new energy vehicle as an example, it usually adopts fully tempered glass or semi-tempered laminated glass.

[0006] For fully tempered glass, the surface stress is large (≥90 MPa), the fragment particles are small, and the number is large (the standard requires 40 to 400 fragments within a range of 50 mm*50 mm, and the fragment length is <100 mm). Once the glass is broken, the escapee or rescuer can easily enter the vehicle or escape from the vehicle, but because the surface stress is large, the impact resistance is also large, and it is difficult to break the glass, a special metal with sharp corners / edges is needed to break the glass.

[0007] For semi-tempered laminated glass, the surface stress is (≥30 MPa), the fragments are long strips, the length exceeds 100 mm, and the number of fragments within a range of 50 mm*50 mm is less than 40. This laminated glass has small stress and is easy to break, but because of the adhesion of the intermediate layer PVB, even if it is broken, the fragments will still adhere to the PVB, and the original shape can still be maintained, and the glass is still stuck in the sealing groove of the door, making it difficult for the escapee or rescuer to enter the vehicle or drill out of the vehicle, and the glass needs to be completely removed to prevent the long strip-shaped fragments from causing harm to the escapee or rescuer.

[0008] In addition, there is a special hardened laminated glass in the existing vehicle door glass, which combines the above two fragment states. The outer piece is fully tempered and granular, and the inner piece adopts hardened fragments in the form of long strips, which are neither easy to break nor allow the escapee or rescuer to quickly pass through.

[0009] If it is difficult to break the window, it will cause difficulty in escaping / rescuing in the case of a failed door handle. In particular, for new energy vehicles, the vehicle battery may be squeezed and deformed and explode, usually within 1 to 2 minutes, and the escape time is very limited.

[0010] To this end, it is necessary to provide a vehicle door window that solves the above problems. SUMMARY

[0011] In view of the defects of the prior art, the vehicle door window and the vehicle provided in the embodiments of the present application can achieve rapid window breaking to form a safe exit in a short time, which is conducive to improving the escape safety performance of the vehicle.

[0012] The specific technical scheme of the embodiments of the present application is as follows:

[0013] The embodiments of the present application provide a vehicle door window, which comprises a glass body, at least a part of the glass body is a weakened area, the weakened area is provided with a weakened structure, and the weakened area is arranged around the end edge of the glass body.

The weakened structure comprises a first defect arranged in at least part of the middle and / or surface of the inner sheet glass, a second defect arranged in at least part of the middle and / or surface of the outer sheet glass, and a third defect arranged on the adhesive layer.

DETAILED DESCRIPTION

[0041] The technical solutions of the present application will be described in detail below with reference to the drawings and specific embodiments. It should be understood that these embodiments are only used to explain the present application and are not intended to limit the scope of the present application. After reading the present application, those skilled in the art can make various equivalent modifications to the present application, which fall within the scope defined by the claims attached hereto.

[0042] The embodiments of the present application provide a vehicle door window and a vehicle, which can realize rapid breaking of the window to form a safe exit in a short time, and are beneficial to improving the escape safety performance of the vehicle.

[0043] Please refer to Figs. 1-9, in the embodiments of the present application, a vehicle door window glass is provided, which can 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 weakened structure, and the weakened area 110 is arranged around the edge of the glass body 100. When the weakened area 110 is subjected to a predetermined force, the glass body 100 at the position of the weakened area 110 can be broken (i.e. broken) within a predetermined time to form a safety exit.

[0044] For example, the edge of the glass body 100 can be understood as the edge of the glass body 100, and the weakened structure can be understood as a structure whose structural strength is less than that of other areas of the glass body 100 except the weakened area 110.

[0045] In the embodiments of the present application, the vehicle door window glass can include a glass body 100, and the specific type of the glass body 100 can include: tempered glass, laminated glass and other glass forms that can be applied to the vehicle door window. In the embodiments of the present application, the glass body 100 is mainly exemplified by tempered glass and laminated glass.

[0046] Of course, the specific arrangement of the glass body 100 can also be other ways, and is not limited to the above description. Those skilled in the art can make other changes under the inspiration of the technical essence of the present application, as long as the functions and effects achieved are the same or similar to the present application, which should be covered within the protection scope of the present application.

[0047] In the embodiments of the present application, at least a part of the glass body 100 is a weakened area 110, the weakened area 110 is provided with a weakened structure, and the weakened area 110 is arranged around the edge of the glass body 100. When the weakened area 110 is subjected to a predetermined force, the glass body 100 at the position of the weakened area 110 can be broken within a predetermined time to achieve a broken window.

[0048] The predetermined time is within 1 minute. When the vehicle door window glass provided by the present application is applied to a vehicle, when an emergency situation occurs and the window needs to be broken, the time for the vehicle door window glass to be broken to form a safety exit is within 1 minute, so as to better meet the escape safety performance requirements of various types of vehicles.

[0049] The specific size of the safety exit needs to meet certain requirements, so that the driver and passenger in the vehicle can evacuate in time. Specifically, the minimum size of the safety exit is 520 mm x 265 mm, so as to meet the escape requirement. In the embodiments of the present application, the specific size of the vehicle door window glass applied in the vehicle can be 700 mm x 600 mm. Of course, the specific size of the safety exit can be adaptively adjusted according to the size of the vehicle door window glass and the like, and the present application does not make a unique numerical limitation here.

[0050] The present application will be described in detail below in combination with specific embodiments and drawings.

[0051] Please refer to FIGS. 1-5, in some embodiments, the glass body 100 can include tempered glass, and the weakening structure is arranged at least in part of the middle and / or surface of the tempered glass along the thickness direction of the glass body 100.

[0052] In the present embodiment, the glass body 100 can include tempered glass, and the surface compressive stress of the tempered glass is greater than or equal to 90 MPa. The thickness of the tempered glass can be between 2.5 mm and 5.0 mm. The thickness of the tempered glass can be different according to the specific application scenario and the different performance requirements of the glass in the specific application scenario. In the embodiments of the present application, the thickness of the tempered glass can also be greater than 5 mm or less than 2.5 mm. For example, the thickness of the tempered glass can be any one of the following thicknesses: 2.85 mm / 3.15 mm / 3.5 mm / 3.85 mm / 4.85 mm. The tempered glass can be fully tempered glass, and the specific form and thickness of the tempered glass can be adaptively adjusted according to the actual application scenario, and the present application does not make a unique limitation here.

[0053] In the present embodiment, some defects can be introduced in the middle of the glass body 100 (as shown in FIG. 3) or the inner surface 111 (as shown in FIG. 4) or the outer surface 112 (as shown in FIG. 5) to form a weakening structure, so as to reduce the strength of the glass body 100 at the weakening area 110 where the weakening structure is arranged, so that the glass can be quickly broken when the position is subsequently knocked, a safety exit is formed, and the short-time escape safety performance requirement is met.

[0054] Specifically, the position, size, geometry, and depth of the defects used to form the weakening structure can be different according to different manufacturing processes and special requirements of the glass, and the present application does not make a specific limitation here. As shown in FIG. 2, the weakening structure can include a plurality of spaced-apart fracture points 101.

[0055] In the embodiment, the area surrounded by the outer edge contour corresponding to the plurality of spaced-apart breaking points 101 is the weakening zone 110, and the weakening zone 110 is not limited in size, shape, etc. herein. The "outer edge contour" can be understood as an imaginary contour line (as shown in FIG. 2) surrounding the plurality of breaking points 101.

[0056] In an embodiment, the weakening zone 110 is arranged close to a door frame to which the glass body 100 is mounted. The door frame can be a frame structure formed on a vehicle door for mounting the glass.

[0057] In the embodiment, the weakening zone 110 is arranged close to the door frame to which the glass body 100 is mounted, i.e., the weakening zone 110 is arranged close to the end edge of the glass body 100. When the weakening zone 110 is arranged close to the door frame to which the glass body 100 is mounted, the deformation of the glass body 100 is relatively small when subjected to external force impact (e.g., window breaking), and the glass body 100 is more likely to be broken. Conversely, if the weakening zone 110 is arranged away from the door frame, such as in the middle region of the glass body 100 in the length and width directions, the deformation of the glass body 100 is relatively large when subjected to external force impact (window breaking), and the deformation can absorb energy, so the glass body 100 is not easily broken.

[0058] As shown in FIG. 1, further, the weakening zone 110 can be arranged at the corner 102 of the glass body 100, i.e., close to the corner of the glass body 100. Specifically, the end edge of the glass body 100 includes a plurality of contour lines (i.e., the edges of the glass body 100), and adjacent two contour lines intersect to form an intersection point, and the corner 102 is a region close to the intersection point. When the glass body 100 is assembled with the door frame, the corner 102 can be located in the window of the door frame without being blocked by the door frame.

[0059] For example, the number of corners can be four, and the weakening zone 110 can be formed in the region of each of the four corners, so that when an emergency situation occurs and the window needs to be broken, any one of the four corner regions can be struck to quickly break the window.

[0060] When the weakening zone 110 is close to the door frame, specifically the corner of the intersection of two door frames, because the door frame exerts a supporting force on the glass body 100, the deformation of the glass body 100 is smaller, and the energy is larger. Once the glass body 100 cannot withstand the impact energy, it is more likely to be broken.

[0061] In the glass body 100, the weakened area 110 is located at a distance greater than or equal to 5 mm from the edge of the glass body 100. The distance between the weakened area 110 and the edge of the glass body 100 is the assembly distance. The assembly distance between the vehicle door window and the door frame varies, and the distance between the weakened area 110 and the edge of the glass body 100 also varies. In general, the weakened area 110 is located in the inner space of the door frame without being blocked by the door frame after the assembly of the glass body 100 and the door frame.

[0062] In an embodiment, the weakened structure is a defect introduced by laser.

[0063] When the weakened structure is introduced by laser, the laser can be introduced before or after the bending forming. In general, the application does not make specific limitations here.

[0064] When the defect is introduced by laser, the shape, structure and position of the defect can be precisely controlled. In general, 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, aesthetics and practicability can be considered.

[0065] Of course, in the embodiments of the application, the defect can also be introduced by other methods, such as physical weakening, chemical weakening, etc. Compared with other methods, the laser method has high controllability and can form a weakened structure with a predetermined shape and structure at a specified position with high precision.

[0066] Please refer to FIGS. 6-9. In another embodiment, the glass body 100 includes a laminated glass including an inner sheet glass 200, an adhesive layer 300 and an outer sheet glass 400 arranged in sequence along the thickness direction, and the weakened structure includes a first defect arranged in at least part of the middle and / or surface of the inner sheet glass 200 along the thickness direction, a second defect arranged in at least part of the middle and / or surface of the outer sheet glass 400 along the thickness direction, and a third defect arranged on the adhesive layer 300. The positions of the first defect and the second defect are at least partially opposite to each other, forming the weakened area 110, and the third defect is located in the weakened area 110.

[0067] The glass body 100 can be a laminated glass, which can include an inner sheet glass 200, an adhesive layer 300, and an outer sheet glass 400 arranged in sequence along the thickness direction. The thickness of the inner sheet glass 200 is between 0.7 mm and 2.5 mm, for example, the thickness of the inner sheet glass 200 can be any one of the following thicknesses: 2.1 / 1.6 / 1.4 / 1.1 / 0.7 mm. The thickness of the outer sheet glass 400 can be between 1.6 mm and 5 mm, for example, the thickness of the outer sheet glass 400 can be any one of the following thicknesses: 3.5 / 3.2 / 2.85 / 2.1 / 1.6 / 1.4 / 1.1 / 0.7 mm. The thickness of the inner sheet glass 200 can be the same as or different from the thickness of the outer sheet glass 400. The adhesive layer 300 can be a transparent thermoplastic polymer film or a colored thermoplastic polymer film, and the thickness of the adhesive layer 300 can be 0.38 mm to 2.28 mm. For example, the thickness of the adhesive layer 300 can be, but is not limited to, 0.38 mm, or 0.76 mm, or 1.14 mm, or 1.52 mm, or 1.9 mm, or 2.28 mm, or other values between 0.38 mm and 2.28 mm. 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 the embodiments of the present application, the material of the adhesive layer 300 is mainly exemplified by polyvinyl butyral (PVB), and when other materials are used for the adhesive layer 300, the present application can be adapted accordingly.

[0068] In the embodiments, the weakening zone 110 can be provided on the inner sheet glass 200 and the outer sheet glass 400, and in addition, a weakening structure is introduced on the adhesive layer 300. Specifically, the weakening structure can include: a first defect provided on at least part of the middle and / or surface of the inner sheet glass 200 in the thickness direction, a second defect provided on at least part of the middle and / or surface of the outer sheet glass 400 in the thickness direction, and a third defect provided on the adhesive layer 300. The positions where the first defect and the second defect are provided at least partially face each other to form the weakening zone 110, and the third defect is located in the weakening zone 110.

[0069] The weakening zone 110 can be located in a water cutting region 500, and the water cutting region 500 can be a region offset upward and downward by 10 mm based on a water cutting center line 501. Specifically, the weakening zone 110 of the inner sheet glass 200 can be located in the water cutting region 500, and the weakening zone 110 of the outer sheet glass 400 can be located in the water cutting region 500.

[0070] For the laminated glass, since the adhesive layer 300 is arranged in the middle, even if the glass is broken, the glass fragments will still be adhered to the adhesive layer 300, and it will be difficult to bend the glass fragments, thereby affecting the time for forming a safe exit.

[0071] When the window needs to be broken, most people will apply a pushing / pulling force to the middle area of the door glass, and the water cutting position (i.e., the water cutting area 500) is a relatively effective force point for breaking the door glass. When the weakening area 110 is arranged at the water cutting area 500, it will be easier to bend the glass later, which can help shorten the time for forming a safe exit. In addition, after the glass is bent at the water cutting position, the window for escaping outside is also the largest, that is, the size of the safe exit can be ensured to be large enough.

[0072] Of course, the definition of the water cutting area 500 can be slightly different according to the size and structure of the door frame to which the laminated glass is specifically installed. Those skilled in the art can adaptively adjust the boundary of the above-mentioned definition based on the specific application scenario under the premise of the disclosure of the present application.

[0073] For the inner glass 200 and the outer glass 400, the way 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 be introduced on the middle or inner surface 111 / outer surface 112 in the thickness direction of the glass. The position, size, geometry, and depth of the defects can be adapted to different manufacturing processes and special needs of the glass. The way of introducing the defects can also be the above-mentioned laser method, that is, the first defect, the second defect, and the third defect can be introduced by laser.

[0074] Specifically, the second defect of the outer glass 400 can include a plurality of spaced-apart breaking points 101. The specific arrangement of the breaking points 101 can refer to the textual description and FIGS. 3-5 of the tempered glass embodiment.

[0075] Specifically, the first defect of the inner glass 200 can include a plurality of spaced-apart breaking points 101 and / or a plurality of openings with a predetermined caliber.

[0076] The first defect of the inner glass 200 can include a plurality of spaced-apart breaking points 101. The specific arrangement of the breaking points 101 can refer to the textual description and FIGS. 3-5 of the tempered glass embodiment.

[0077] In addition, the first defect of the inner sheet glass 200 can also have other forms, for example, the first defect of the inner sheet glass 200 can include a plurality of openings with a predetermined caliber. The openings can be through holes or blind holes. Since the inner sheet glass 200 is close to the inside of the vehicle, a series of small-caliber through holes or blind holes can be arranged on the glass, thereby reducing the strength of the inner sheet glass 200 at the position of the above-mentioned openings, i.e., forming the first defect, and meanwhile, not negatively affecting the appearance or reliability of the entire glass.

[0078] Referring to FIGS. 7 and 8, in an embodiment, the third defect can include continuous or discontinuous preset fracture lines 301 covering the water cutting center line 501.

[0079] In the embodiment, as shown in FIG. 7, the adhesive layer 300 can be provided with continuous preset fracture lines 301 at the water cutting position by means of laser or the like. The continuous fracture lines 301 can be an integral strip-shaped crack extending longitudinally along the water cutting center line 501.

[0080] Alternatively, as shown in FIG. 8, the adhesive layer 300 can be provided with a plurality of spaced preset fracture lines 301 at the water cutting position by means of laser or the like. The plurality of spaced preset fracture lines 301 can also be arranged longitudinally and spaced along the water cutting center line 501.

[0081] Overall, the end of the fracture line 301 is spaced from the end edge of the laminated glass by a predetermined distance, thereby avoiding that the fracture line 301 causes external water vapor to enter the interior of the laminated glass. Specifically, the end of the preset fracture line 301 is spaced from the end edge of the glass body 100 by at least 5 mm, thereby reliably blocking external water vapor and avoiding problems such as delamination and bubbles of the adhesive layer 300 of the laminated glass caused by external environment.

[0082] For the inner sheet glass 200 or the outer sheet glass 400, the defect thereon can be introduced before bending and forming or after bending and forming.

[0083] For the third defect of the adhesive layer 300, if it is introduced before bonding, the adhesive layer 300 will gradually melt during the bonding process under the action of high temperature and high pressure, so that the introduced fracture line 301 will also fuse. Therefore, in order to ensure that the fracture line 301 is not affected by high temperature and high pressure and fails, the fracture line 301 needs to be introduced after the laminated glass is bonded.

[0084] In order to verify the escape safety performance of the vehicle door window glass provided in the embodiments, the inventors made the following comparative experiments. The experimental steps are as follows:

[0085] The safety hammer is used to simulate the process of breaking the glass from inside the vehicle, and the glass is broken and pushed out to form a safe exit. The escape time from breaking the window to forming a safe exit is recorded.

[0086] Table 1

[0087] Please refer to Table 1, which can also be fully proved by the above experiments:

[0088] The vehicle door window glass provided in the embodiments of the present application is more likely to break the glass at the weakened area 110 with a weakened structure, and can achieve rapid window breaking 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. Especially for the laminated glass provided with the adhesive layer 300, the weakened area 110 and the pre-set fracture 301 are arranged at the water cutting position, so that the glass is more easily bent to form a safe exit with a large enough area, which is beneficial to improve the escape safety performance of the vehicle.

[0089] The vehicle provided in the embodiments of the present application includes the above-mentioned vehicle door window glass. The vehicle can achieve the technical effects achieved by the vehicle door window glass embodiments by being provided with the above-mentioned vehicle door window glass. For details, please refer to the specific description of the above embodiments, which will not be repeated here.

[0090] The vehicle includes a vehicle body, and the vehicle body has a door frame for mounting the glass. The door frame is provided with the vehicle door window glass provided in the above embodiments.

[0091] The vehicle door window glass provided in the embodiments of the present application can be applied to the doors and windows of various vehicles, such as rail vehicles and new energy vehicles.

[0092] For example, taking the current new energy vehicle as an example, in order to reduce the wind resistance and improve the appearance of the vehicle, the handle is designed as a hidden structure. According to the calculation, a single hidden door handle can reduce the wind resistance by 0.003Cd, and four door handles can reduce the wind resistance by 0.012Cd. The wind resistance coefficient of a pure electric vehicle can be reduced by 0.01Cd, and the range per 100 kilometers can be increased by more than 5 kilometers.

[0093] Although the design of the invisible door handle can improve the overall appearance and aerodynamic performance of the vehicle, it also has some safety hazards, including:

[0094] 1. Difficulty in escaping: In an emergency situation, vehicles lack obvious identification or visibility (especially some models without door handles, vehicles with NFC, fingerprint, or button switches through B / C pillars) that can make it take passengers longer to successfully open the doors;

[0095] 2. Difficulty or unfamiliarity in operation: Some invisible door handle designs may require specific operation methods or greater force to open, which can make it difficult for some passengers to quickly open the doors in an emergency situation;

[0096] 3. Technical failure: Invisible door handles usually rely on electronic or mechanical systems to achieve opening, and if these systems fail or lose power, passengers may not be able to open the doors;

[0097] 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 operation difficulties, increasing the safety risk in an emergency situation; there are also some settings that cause the child lock to be unable to open the door from the inside.

[0098] During vehicle use, for example, when a child is trapped inside the vehicle and cannot open the door from the inside, it is necessary to break the window.
