Description

Technical Field

[0001] This invention relates to the field of rail vehicles, and provides a window, a rail vehicle, and a method for installing the window. Background Technology

[0002] For rail vehicle windows, drilling holes for bolting is generally not permitted; windows are mostly fixed to the vehicle body using adhesive. However, adhesives are prone to aging and failure after long-term use, posing a risk of windows detaching outwards and creating a significant safety hazard for vehicle operation and passenger safety.

[0003] Wrap-in windows use a mechanical stop where the glass edge extends into the vehicle frame, preventing the window from detaching if the adhesive fails. However, traditional wrap-in window structures require the removal of the interior trim panels around the window from the inside of the vehicle for inspection and replacement, causing significant inconvenience. Furthermore, some urban rail projects do not allow the removal of interior trim, rendering this structure unusable. Externally bonded windows can be installed and removed from the outside of the vehicle without removing interior trim panels, but they lack mechanical restraint and rely entirely on adhesive, leaving them at risk of detachment if the adhesive fails. Summary of the Invention

[0004] This invention provides a vehicle window, a rail vehicle, and a method for installing the vehicle window, in order to solve the shortcomings of related technologies that cannot simultaneously achieve mechanical anti-detachment of vehicle windows and the ability to install and remove interior trim panels from the outside of the vehicle, thereby achieving the goal of preventing vehicle windows from detaching and allowing for external installation and removal without the need to remove interior trim panels.

[0005] This invention provides a vehicle window suitable for installation on a vehicle body. The vehicle body has an installation opening and a vehicle frame surrounding the installation opening. The vehicle window includes an outer glass layer, an inner glass layer, and an intermediate layer connecting the outer glass layer and the inner glass layer. The intermediate layer covers the overlapping area of ​​the outer glass layer and the inner glass layer. The inner glass layer has a dimension greater than the mounting opening in the first direction, or the inner glass layer has a dimension greater than the mounting opening in the second direction. The portion of the inner glass layer extending beyond the mounting opening is used to mate with the inner stop of the vehicle body frame. In the same direction where the inner glass layer has a dimension greater than the mounting opening, the outer glass layer has a dimension not greater than the mounting opening. Wherein, the first direction is parallel to the height direction of the vehicle body, and the second direction is parallel to the length direction of the vehicle body.

[0006] According to one embodiment of the present invention, the outer glass is bonded to the vehicle frame, and the outer surface of the outer glass is flush with the outer surface of the vehicle frame.

[0007] According to one embodiment of the present invention, the vehicle frame is provided with a connecting portion, the connecting portion being located on the side of the vehicle frame facing outwards, and the inner surfaces of the outer glass at both ends along the first direction or the second direction are connected to the connecting portion by a first adhesive.

[0008] According to one embodiment of the present invention, a gap is provided between the peripheral edge of the outer glass and the vehicle frame, and the gap is filled with a second adhesive.

[0009] According to one embodiment of the present invention, the inner glass is a single-layer glass or a multi-layer insulated glass.

[0010] According to one embodiment of the present invention, the intermediate layer is a thermoplastic resin film.

[0011] This invention also provides a rail vehicle, including a car body and the aforementioned window, wherein the car body has a mounting opening and a car body frame surrounding the mounting opening, and the window is mounted to the car body frame via the mounting opening.

[0012] This invention also provides a method for installing the above-mentioned vehicle window, wherein the vehicle window is assembled from the outside of the vehicle body through the installation opening from the outside in. After assembly, the portion of the inner glass extending beyond the installation opening forms a covering and blocking structure with the inner side of the vehicle frame, and the outer glass is bonded to the vehicle frame.

[0013] According to one embodiment of the present invention, the inner glass layer has a dimension larger than the mounting opening and the outer glass layer in the first direction, and the outer glass layer has a dimension larger than the inner glass layer in the second direction. The method for installing the vehicle window includes the following steps: Tilt the window so that one end of the inner glass in the first direction extends into the vehicle through the mounting port; Rotate the window so that the other end of the inner glass extends into the vehicle through the mounting port in the first direction; Adjust the posture and position of the vehicle window so that the outer surface of the outer glass is flush with the outer surface of the vehicle frame; Adjust the gap between the outer glass and the vehicle frame; The outer glass layer is bonded to the vehicle frame.

[0014] According to one embodiment of the present invention, the step of adjusting the gap between the outer glass and the vehicle frame includes: inserting a support block between the bottom of the outer glass and the vehicle frame to temporarily support the window; And / or, the step of bonding the outer glass to the vehicle frame includes: At both ends of the outer glass layer along the second direction, the outer glass layer is connected to the vehicle frame using a first adhesive. The gap between the outer glass and the vehicle frame is filled with a second adhesive.

[0015] The vehicle window, rail vehicle, and window installation method provided by this invention, through a specific dimensional matching relationship between the inner and outer glass layers and the vehicle body mounting opening, balances mechanical anti-detachment and external assembly structural foundations, overcoming the contradictions of traditional wrap-around windows requiring in-vehicle disassembly and ordinary externally bonded windows lacking mechanical anti-detachment limits. When the adhesive between the outer glass layer and the vehicle body frame ages and fails, the wrapped portion of the inner glass layer is blocked by the inside of the vehicle body frame, preventing the entire window from detaching outwards, thus achieving mechanical anti-detachment protection for the wrap-around window and eliminating the operational safety hazard of windows falling outwards. During assembly and subsequent maintenance and replacement, the window can be disassembled and installed from the outside of the vehicle without removing the interior trim panels around the perimeter, meeting the maintenance requirements of urban rail project owners for maintenance without disassembling the interior.

[0026] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] In related technologies, the outer glass of a wraparound window is designed so that the outer rim is smaller than the inner glass. This allows the inner glass to be secured by a protruding edge on the vehicle body. However, this complete rim obstruction means that replacement can only be done from inside the vehicle, requiring the removal of the inner glass. Considering external installation, windows are typically glued to the vehicle frame as a whole. This type of externally glued window cannot achieve a wraparound design and is prone to detachment when the adhesive fails.

[0031] To solve the above problems, such as Figures 1 to 7 As shown, this embodiment of the invention provides a vehicle window 100, which is suitable for installation on a vehicle body 200. The vehicle body 200 has an installation opening 210 and a vehicle frame 220 surrounding the installation opening 210. The vehicle window 100 includes: an outer glass layer 110, an inner glass layer 120, and an intermediate layer 130 connecting the outer glass layer 110 and the inner glass layer 120. The intermediate layer 130 covers the overlapping area of ​​the outer glass layer 110 and the inner glass layer 120. The inner glass layer 120 has a dimension larger than the installation opening 210 along a first direction. The dimension of the inner glass 120 along the first direction, or the dimension of the inner glass 120 along the second direction, is greater than the dimension of the mounting opening 210 along the second direction. The portion of the inner glass 120 extending beyond the mounting opening 210 is used to mate with the inner stop of the vehicle frame 220. In the same direction where the dimension of the inner glass 120 is greater than the dimension of the mounting opening 210, the dimension of the outer glass 110 is not greater than the dimension of the mounting opening 210. The first direction is parallel to the height direction of the vehicle body 200, and the second direction is parallel to the length direction of the vehicle body 200.

[0032] Specifically, the inner glass 120 can cooperate with the vehicle frame 220 in a first or second direction to form a wrap-around anti-detachment structure. Even if the adhesive fails, the window 100 will not detach from the vehicle body 200, thus avoiding the safety risk of the window 100 falling outward from the structural source. Moreover, the window 100 uses laminated glass, with the outer glass 110 and the inner glass 120 pressed together by an intermediate layer 130. The two layers of glass are difficult to separate. Even if the adhesive between the outer glass 110 and the vehicle frame 220 fails or the outer glass 110 cracks, the fragments of the outer glass 110 will be adhered and restrained by the intermediate layer 130, preventing the fragments from flying outward and falling off, further improving vehicle operation safety.

[0033] In the same direction where the inner glass 120 is larger than the mounting opening 210, the outer glass 110 is no larger than the mounting opening 210. The outer glass 110 will not cause interference or obstruction in this direction. The entire window 100 assembly is capable of being tilted and screwed into the vehicle body 200 for assembly. During assembly and subsequent maintenance and replacement, the window 100 can be disassembled and installed from outside the vehicle without removing the interior trim panels around the vehicle. This meets the maintenance requirements of urban rail project owners for maintenance without disassembling the interior and significantly reduces the difficulty of replacing the window 100.

[0034] It is understandable that, such as Figures 1 to 3 As shown, the outer glass layer 110 and the inner glass layer 120 form a cross-shaped structure of different sizes. For example, when the dimension of the inner glass layer 120 along the first direction is greater than the dimension of the mounting opening 210 along the first direction, the dimension of the inner glass layer 120 along the first direction is greater than the dimension of the outer glass layer 110 along the first direction. At the same time, the dimension of the inner glass layer 120 along the second direction is smaller than the dimension of the outer glass layer 110 along the second direction. Alternatively, when the dimension of the inner glass layer 120 along the second direction is greater than the dimension of the mounting opening 210 along the second direction, the dimension of the inner glass layer 120 along the second direction is greater than the dimension of the outer glass layer 110 along the second direction. At the same time, the dimension of the inner glass layer 120 along the first direction is smaller than the dimension of the outer glass layer 110 along the first direction.

[0035] The outer glass 110 and the inner glass 120 are integrated into a single structure through an intermediate layer 130. Preferably, the intermediate layer 130 is a thermoplastic resin film, which has good toughness and high bonding strength, and can reliably bond the outer glass 110 and the inner glass 120 into a whole.

[0036] In specific examples, the intermediate layer 130 can be made of at least one of polyvinyl butyral (PVB), ionomer polystyrene (SGP), ethylene-vinyl acetate copolymer (EVA), and thermoplastic polyurethane (TPU), which can be flexibly selected according to the vehicle's sound insulation, weather resistance, and cost requirements. The intermediate layer 130 is not limited to a single-layer film; it can also be made of two or more composite films of different materials, such as a PVB and TPU composite, while simultaneously ensuring weather resistance and impact resistance. The intermediate layer 130 can be locally fitted with color or light-blocking layers to achieve 100% light-blocking effect for the window.

[0037] Based on the encapsulation structure of the inner glass 120, the inner glass 120 is encapsulated in one direction, while the outer glass 110 is bonded to the vehicle body 200 in the other direction. In this way, the two glass layers form an intersecting form, so that the inner and outer glass layers 110 can each achieve the functions of encapsulation and anti-detachment and external bonding and fixation. The encapsulation and anti-detachment function and the external bonding function are integrated into the same set of window 100 components, overcoming the contradiction that the two cannot be achieved in the traditional structure.

[0038] Specifically, such as Figure 4 As shown, the outer glass 110 is bonded to the car body frame 220, and the outer surface of the outer glass 110 is flush with the outer surface of the car body frame 220. This design satisfies the design requirements of a smooth appearance for the rail vehicle body 200, with no protrusions or exposed fasteners on the exterior, thus reducing wind resistance during high-speed operation. Furthermore, the bonding of the outer glass 110 to the outside of the car body 200 allows the entire bonding process to be carried out outside the vehicle, facilitating on-site caulking.

[0039] According to one embodiment of the present invention, the vehicle frame 220 is provided with a connecting portion 230, the connecting portion 230 is located on the side of the vehicle frame 220 facing outward, and the inner surfaces of the outer glass 110 at both ends along the first direction or the second direction are connected to the connecting portion 230 by a first adhesive 140.

[0040] For example, such as Figure 5 As shown, the outer glass 110 is connected to the connecting part 230 at both ends along the second direction by the first adhesive 140, which ensures the connection strength between the window 100 and the vehicle body 200. The first adhesive 140 can bear the weight of the window 100 and the aerodynamic load during vehicle operation, ensuring a reliable connection between the window 100 and the vehicle body 200.

[0041] The width of the first adhesive 140 can be flexibly adjusted according to actual needs to meet the bonding strength requirements; the first adhesive 140 can be pre-applied to the connecting part 230 or the outer glass 110, and cured under pressure after assembly to form a reliable bond.

[0042] Furthermore, a gap is provided between the periphery of the outer glass 110 and the vehicle frame 220, and the gap is filled with a second adhesive 150 to seal the assembly gap, preventing external dust, rainwater and other substances from entering the vehicle through the assembly gap, thus achieving dustproof and waterproof protection and improving the overall sealing performance of the window 100.

[0043] The gap between the outer glass 110 and the vehicle frame 220 can be set to 6mm-10mm. This gap provides space for the assembly operation of tilting and screwing the window 100 in, and can also absorb the manufacturing and assembly errors of the vehicle body 200 and the glass, making it easier for the second adhesive 150 to fill and form.

[0044] The first adhesive 140 and the second adhesive 150 mentioned above can be made of the same material or different materials, and the selection can be made according to the structural stress, weather resistance and sealing requirements.

[0045] The overlap size of the inner glass 120 on one side can be selected with reference to the assembly gap between the outer glass 110 and the vehicle frame 220. The overlap size can be consistent with the assembly gap size or slightly smaller than the assembly gap. For example, the overlap size is preferably 5mm-10mm, leaving a tolerance margin to reduce the difficulty of on-site assembly. The difference in size between the two can offset the manufacturing and assembly errors of the vehicle body 200 and glass components, making it easier for the inner glass 120 to be smoothly inserted into the inside of the vehicle frame 220 when the window 100 is tilted, avoiding jamming or interference during the assembly process.

[0046] Furthermore, such as Figure 6As shown, rubber strips 160 are provided at both ends of the inner glass 120 along the first direction, facing the outer glass 110. During the bonding process between the outer glass 110 and the vehicle frame 220, the rubber strips 160 can prevent excess adhesive from seeping inward, avoiding adhesive overflow into the inside of the window 100 and contaminating the glass or interior components. Simultaneously, the rubber strips 160 also provide cushioning and shock absorption, buffering the vibration and impact on the glass during vehicle operation. It is understandable that the position of the rubber strips 160 can be flexibly adjusted for different specifications of the inner glass 120. In addition to the rubber strips 160, dot-distributed rubber protrusions, foam sealing rings, etc., can also be used, which can similarly prevent adhesive overflow and provide cushioning and shock absorption.

[0047] Based on the above embodiments, to improve the sound insulation and heat insulation performance of the entire window, the inner glass 120 may optionally be a single-pane glass, multi-pane insulated glass, or other framed structural configurations. For example, Figure 6 The inner glass 120 is a double-glazed glass, which forms a hollow heat insulation cavity. Together with the laminated intermediate layer 130, it forms a laminated-hollow composite structure, which can simultaneously improve the heat insulation and sound insulation effect of the window 100. Furthermore, without changing the overlapping structure of the inner glass 120, it can still achieve the functions of mechanical anti-detachment and external installation without removing the interior parts.

[0048] The window 100 structure of this invention achieves the installation effect of both covering and eliminating the need for interior decoration, meeting the current operation and maintenance requirements of urban rail vehicles, and has the following advantages: First, after assembly, the outer surface of the window 100 is flush with the profile of the car body 200, with no protruding window frame or exposed fasteners, and the exterior of the car body 200 is smooth, which not only conforms to the appearance design specifications of rail vehicles, but also reduces air resistance during high-speed train operation; Second, the window 100 can be installed and replaced directly from the outside of the vehicle, without the need to remove the interior decorative panels on the inside of the car, making it suitable for maintenance of urban rail projects that do not require interior decoration removal. The requirements are as follows: First, the inspection and replacement procedures should be greatly simplified to reduce operation and maintenance costs. Second, relying on the mechanical stop cooperation between the inner glass 120 and the inner side of the car frame 220, even if the adhesive ages or fails to adhere, it can still limit the window 100, effectively preventing the window 100 from falling out of the car and avoiding the safety hazards of glass falling off under the conditions of train operation and tunnel pressure difference. Third, the glass configuration is flexible and can be configured with various forms such as laminated glass and laminated insulated composite glass, which can be adapted to the corresponding sound insulation and heat insulation performance indicators according to the needs of different line conditions, thus broadening the application scenarios of the product.

[0049] Furthermore, such as Figures 1 to 7As shown, this embodiment of the invention also provides a rail vehicle, including a car body 200 and the aforementioned window 100. The car body 200 has a mounting opening 210 and a car body frame 220 surrounding the mounting opening 210. The window 100 is mounted to the car body frame 220 via the mounting opening 210. The rail vehicle employing the aforementioned window 100 structure, while meeting the requirements of overall vehicle appearance and aerodynamic performance, possesses both anti-detachment protection for the window 100 in case of adhesive failure and allows for external installation and removal of the window 100 without disassembling the interior trim panels, reducing the difficulty of later maintenance. It is particularly suitable for the usage requirements of high-speed urban rail, tunnels with large pressure differentials, elevated structures, and monorail vehicles.

[0050] Furthermore, this embodiment of the invention also provides a method for installing the aforementioned vehicle window 100. The vehicle window 100 is assembled from the outside of the vehicle body 200 through the mounting opening 210 inwards. After assembly, the portion of the inner glass 120 extending beyond the mounting opening 210 forms a covering and stopping structure with the inner side of the vehicle body frame 220, and the outer glass 110 is bonded to the vehicle body frame 220. All operations in this installation method can be completed outside the vehicle, eliminating the need to enter the passenger compartment to disassemble interior components, thus simplifying on-site assembly and subsequent replacement processes.

[0051] According to one embodiment of the present invention, the inner glass 120 has a dimension greater than that of the mounting opening 210 and the outer glass 110 in the first direction, the outer glass 110 has a dimension smaller than that of the mounting opening 210 in the first direction, and the outer glass 110 has a dimension greater than that of the inner glass 120 in the second direction.

[0052] The installation method for car windows includes the following steps: Tilt the window 100 so that the inner glass 120 extends into the vehicle through the mounting port 210 at one end in the first direction. Rotate the window 100 so that the inner glass 120 extends into the vehicle through the mounting port 210 at the other end in the first direction; Adjust the posture and position of the window 100 so that the outer surface of the outer glass 110 is flush with the outer surface of the vehicle frame 220; Adjust the gap between the outer glass 110 and the vehicle frame 220; The outer glass 110 is bonded to the vehicle frame 220.

[0053] Specifically, during installation, one end of the inner glass 120 (top or bottom) first enters the vehicle, then rotates and the other end enters, depending on the actual installation situation. For ease of understanding, [further details are provided]. Figure 7 and Figure 8 The following describes the installation process of window 100, taking the lower end of the inner glass 120 entering the vehicle first as an example: First, tilt the window 100 so that the lower end of the inner glass 120 is inserted into the inside of the vehicle frame 220 through the mounting port 210. Then, move the corresponding edge of the outer glass 110 of the window 100 down to contact the vehicle body 200. Rotate the entire window 100 assembly to slowly move the other side of the inner glass 120 into the vehicle. After the entire side of the inner glass 120 is inside the vehicle frame 220, adjust the posture and position of the window 100 so that the outer surface of the outer glass 110 is flush with the outer surface of the vehicle frame 220. Then, slightly adjust the position of the window 100 upwards and adjust the gap between the outer glass 110 and the vehicle frame 220. Finally, complete the adhesive bonding operation between the outer glass 110 and the vehicle frame 220.

[0054] Further, the step of adjusting the gap between the outer glass 110 and the vehicle frame 220 includes: inserting a support block 170 between the bottom of the outer glass 110 and the vehicle frame 220 to temporarily support the window 100. During the assembly stage when the adhesive has not yet cured and does not have load-bearing capacity, the support block 170 can support the weight of the window 100 to prevent it from shifting downwards under gravity, ensuring uniform gaps between the top and bottom of the outer glass 110 and the vehicle frame 220, and providing stable working conditions for subsequent adhesive application. The support block 170 is located on the outside of the vehicle body 200 and can be installed and removed from the outside. The support block 170 can be made of non-metallic materials such as hard plastic or rubber, as long as it can achieve temporary support and positioning; this invention does not specifically limit the material of the support block 170.

[0055] Furthermore, the step of bonding the outer glass 110 to the vehicle frame 220 includes: At both ends of the outer glass 110 along the second direction, the connection portion 230 between the outer glass 110 and the vehicle frame 220 is connected using a first adhesive 140. It can be understood that the first structural adhesive can be pre-applied to the connection portion 230 of the vehicle frame 220, or pre-applied to the inner surface of the corresponding position of the outer glass 110. After the window 100 is in place, it is pressed together to achieve bonding.

[0056] After the first adhesive 140 has cured, the outer glass 110 is basically fixed and limited. The weight of the window 100 and the aerodynamic load under operating conditions are borne by the cured first structural adhesive, and the outer glass 110 will not shift. At this point, the support block 170 can be removed and reused. Alternatively, the support block 170 can be left unremoved and subsequently wrapped and covered with the second adhesive 150, sealing the support block 170 inside the gap, which also meets the requirements for vehicle use.

[0057] Finally, the second adhesive 150 is used to fill the circumferential gap between the outer glass 110 and the vehicle frame 220 to complete the gap sealing treatment, preventing rainwater and dust from entering the vehicle through the assembly gap, and achieving a waterproof and dustproof seal on the outside of the window 100.

[0058] When the window 100 needs to be inspected or replaced, all work can be carried out outside the vehicle: First, cut off the second adhesive 150 on the outside. If the support block 170 is not removed, remove the support block 170 from outside the vehicle, then cut off the first adhesive 140 to release the adhesive constraint between the outer glass 110 and the vehicle frame 220. Then, following the reverse order of installation, tilt and rotate the window 100 so that the window 100 can be removed directly from the outside of the vehicle body 200. The interior trim panels inside the vehicle do not need to be removed throughout the process.

[0059] The present invention provides a vehicle window 100, a rail vehicle, and a method for installing the vehicle window 100. Through a specific dimensional matching relationship between the inner glass layer 120, the outer glass layer 110, and the mounting opening 210 of the vehicle body 200, it balances mechanical anti-detachment and external assembly structural foundations, overcoming the contradictions of traditional wrap-around windows 100 requiring in-vehicle disassembly and ordinary externally bonded windows 100 lacking mechanical anti-detachment limits. When the adhesive between the outer glass layer 110 and the vehicle body frame 220 ages and fails, the covered portion of the inner glass layer 120 is blocked by the inside of the vehicle body frame 220, restricting the entire window 100 from detaching outwards. This achieves mechanical anti-detachment protection for the wrap-around window 100, eliminating the operational safety hazard of the window 100 falling outwards. During assembly and subsequent maintenance and replacement, the window 100 can be disassembled and installed from the outside of the vehicle without removing the interior trim panels around the perimeter, meeting the maintenance requirements of urban rail project owners for maintenance without disassembly of the interior.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
