[0001] The present application relates to the technical field of rail vehicles, and particularly to a cab window sealing structure, a cab and a rail vehicle applying such a cab window sealing structure. Background Art

[0002] Rail vehicles generally include a cab hood and a car body, which are manufactured separately and then assembled into one. As an important part of a rail vehicle, when the cab hood is closed, it can provide protection for the front-end car body and the driver during operation. In the prior art, the cab hood of a cab is usually of an integral structure. Especially in the application scenarios of some high-speed rail trains, in order to ensure a small air resistance, the cab hood is usually streamlined and integrally manufactured, and is connected to the car body skeleton through brackets, connecting frames, etc.

[0003] In order to facilitate the driver to observe the road conditions, windows are provided in the front and both sides of the cab hood. During the high-speed operation of a rail train, the cab is subject to the greatest air resistance. If the windows are not sealed or the sealing is poor, the high-speed flowing air enters from the gap between the window and the car body, bringing in dust and air flow, which easily damages the equipment and interferes with the driver's driving. Summary of the Invention

[0042] In order to make the technical solutions and advantages in the embodiments of the present application clearer and more understandable, the following further elaborates on the exemplary embodiments of the present application with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0043] In the process of implementing the present application, the inventor found that since most of the cowls of the current cab of rail vehicles are integrally formed structures, the glass of the front window and side windows of the cab is adapted to this structure, and is installed on the cowl and then sealed. Even in some designs, the front window and side windows are designed as a curved integral structure. The front windows and rear windows of these designs cannot be adapted to the split cowl, and the sealing effect is not good enough.

[0044] In view of the above problems, in the embodiments of the present application, a sealing structure for the cab windows is provided. Taking the application on rail vehicles as an example, the implementation manner of the sealing structure for the cab windows is specifically described as follows Figures 1-25 As shown, in the embodiments of the present application, the longitudinal direction of the rail vehicle is called the longitudinal direction, the width direction is called the transverse direction, the height direction is called the vertical direction, the direction towards the running direction of the rail vehicle is called the front, the direction towards the opposite direction of the running direction of the rail vehicle is called the rear, the direction towards the outside of the cab is called the outside, and the direction towards the inside of the cab is called the inside.

[0045] As Figure 1 and Figure 8The cab window sealing structure shown includes a car body frame 104, which is the main load-bearing structure at the front end of the car body, a windshield glass support plate 149, and a hood side wall panel 144. The car body frame 104 is used to install the main components of the cab. The rear end of the car body frame 104 is connected to the car body, and a front window opening is provided at the front, and side window openings are symmetrically provided on both sides. The windshield glass support plate 149 is arranged at the front window opening of the car body frame 104, and the windshield glass of the vehicle is installed on the windshield glass support plate 149 through a sealing structure. The hood side wall panels 144 are symmetrically arranged on both sides of the car body frame 104, and side window installation openings are provided in the areas of the hood side wall panels 144 corresponding to the side window openings of the car body frame 104, and the side window glass of the vehicle is installed at the side window installation openings of the hood side wall panels 144 through a sealing structure.

[0046] The cab window sealing structure provided in the embodiment of the present application is applicable to a split cab hood structure. The windshield glass is sealed and installed on the windshield glass support plate, and the side window glass is sealed and installed on the side wall, forming a first seal. Subsequently, when the windshield glass support plate and the side wall are assembled to the car body frame, further sealing can be carried out to form a two-layer sealing structure, thereby achieving a better sealing effect.

[0047] The embodiment of the present application provides a specific implementation manner of the structure and installation of a windshield glass support plate, such as Figures 1 to 7 shown, the windshield glass support plate 149 is a frame-shaped structure adapted to the front window opening of the car body frame 104, and the periphery of its frame is adhesively bonded to the outer periphery of the front window opening of the car body frame 104 through a sealant. The windshield glass support plate 149 and the front window opening of the car body frame 104 are adhesively bonded through a sealant, which can form a second sealing structure at the front window, further strengthening the sealing effect at the front window opening.

[0048] In order to make the connection between the windshield glass support plate 149 and the car body frame 104 more stable, in some specific embodiments, installation points for strengthening the connection are provided on the periphery of the frame of the windshield glass support plate 149. Among them, a windshield support plate top installation point 1491 is provided at the top of the windshield glass support plate 149, and the windshield support plate top installation point 1491 is connected to the car body frame C-shaped groove 1041 at the corresponding position through a windshield connection plate 1494 and a fastener 191. Specifically, the top of the windshield glass support plate 149 extends upward and fits the surface of the car body frame 104 on the upper side of the front window opening. The upward-extending part of the top of the windshield glass support plate 149 is integrated with a stud structure, and the stud structure is connected to the windshield connection plate 1494. The windshield connection plate 1494 fits the surface where the top of the windshield glass support plate 149 fits the car body frame 104 and extends upward to the car body frame C-shaped groove 1041 integrated at the top of the car body frame 104, and the windshield connection plate 1494 is connected to the car body frame C-shaped groove 1041 through a fastener 191.

[0049] Further, a windshield support plate bottom mounting point 1492 is provided at the bottom of the windshield support plate 149. The windshield support plate bottom mounting point 1492 is connected to the vehicle body at the corresponding position through a windshield connecting plate 1494 and a fastener 191. Specifically, the bottom of the windshield support plate 149 extends horizontally inward and fits against the surface of the vehicle body frame 104 at the bottom of the front window opening. A stud structure is integrated on the horizontally extending portion at the bottom of the windshield support plate 149. The stud structure is connected to the windshield connecting plate 1494. The windshield connecting plate 1494 fits against the surface where the bottom of the windshield support plate 149 is in contact with the vehicle body frame 104 and extends horizontally to a vehicle body frame C-shaped groove 1041 integrated at the corresponding position on the vehicle body frame 104. The windshield connecting plate 1494 and the vehicle body frame C-shaped groove 1041 are connected through a fastener 191.

[0050] Further, windshield support plate side mounting points 1493 are provided on both sides of the inner surface of the windshield support plate 149. A windshield connection bracket 1495 is integrated at the windshield support plate side mounting points 1493. The windshield connection bracket 1495 is connected to the vehicle body frame C-shaped groove 1041 at the corresponding position through a windshield connecting plate 1494 and a fastener 191. Specifically, the windshield connection bracket 1495 integrated at the windshield support plate side mounting points 1493 is of a "U" shape. Its open side is fixed on the inner surfaces on both sides of the windshield support plate. The bottom of its "U" shape is connected to one fold of an "L" - shaped windshield connecting plate 1494 through a fastener 191. The other fold of the "L" - shaped windshield connecting plate 1494 is connected to the vehicle body frame C-shaped groove 1041 provided at the corresponding position on the inner side of the front window opening of the vehicle body frame 104 through a fastener 191.

[0051] By adopting integrated fixed connection points and mechanically connecting the windshield support plate 149 to the vehicle body frame 104 through connecting plates and fasteners of various structures, the connection stability of the windshield support plate can be increased, and the structure falling off caused only by the aging of the sealant can be avoided.

[0052] In some specific embodiments, the windshield support plate 149 is made of fiberglass reinforced plastic material. Making the windshield support plate 149 with fiberglass reinforced plastic material can, in addition to meeting the strength and installation requirements, also be designed into various shapes such as double - curved surfaces to meet different aesthetic styling solutions.

[0053] Further, the periphery of the windshield is bonded to the windshield support plate 149 through an adhesive 14961, and the windshield support plate 149 fixes the windshield through its integrated limiting structure.

[0054] For the side window, the embodiments of the present application provide a specific implementation of the side wall panel of the cowl: on the outer surface of the side wall panel 144 of the cowl, a circle is recessed inward around the periphery of the side window installation opening to form a side window bonding surface, and the side window is bonded to the side window bonding surface through a sealant to form a seal. The seal formed by bonding the glass window panel of the side window to the side wall panel is the first seal. Compared with the frame-type seal, the bonding is more reliable and the sealing performance is better.

[0055] Furthermore, on the inner surface of the side wall panel 144 of the cowl, a side wall panel bonding glue shaping structure 1446 is also integrated. The side wall panel bonding glue shaping structure 1446 is formed by enclosing the periphery of the side window installation opening with a plate-shaped material perpendicular to the side wall panel 144. The shape and size of the contour enclosed by the side wall panel bonding glue shaping structure 1446 are adapted to the shape and size of the inner contour of the side window opening of the vehicle body frame 104. The side wall panel bonding glue shaping structure 1446 and the side window opening of the vehicle body frame 104 are bonded through a sealant to form a seal. The seal between the side wall panel bonding glue shaping structure 1446 and the side window opening of the vehicle body frame 104 is the second seal, and the double-seal structure further improves the sealing performance of the side window.

[0056] To make the connection between the side wall panel 144 of the cowl and the vehicle body frame 104 more stable, as Figure 9 shown Figure 10 in some specific embodiments, mounting points for strengthening the connection are provided on the inner side of the side wall panel 144 of the cowl.

[0057] As Figures 11 to 13 shown, a cowl side wall panel roof mounting point 1441 is provided at the top of the side wall panel 144 of the cowl. Among them, an "L"-shaped cowl side wall panel connection code 1445 is integrated at the cowl side wall panel roof mounting point 1441 located above the rear side of the top of the side wall panel. One side of this cowl side wall panel connection code 1445 is integrated on the side wall panel 144 of the cowl, and the other side is bent and connected to the corresponding vehicle body frame C-shaped groove through a fastener 191; one end of the cowl side wall panel connection code 1445 integrated at the cowl side wall panel roof mounting point 1441 located below the rear side of the top of the side wall panel is integrated on the inner wall of the side wall panel 144 of the cowl, and the other end is bent and extends obliquely downward to the vehicle body frame C-shaped groove 1041 at the corresponding position and is bent again to fit the mounting surface of the vehicle body frame C-shaped groove 1041 at this place, and is connected to the vehicle body frame C-shaped groove 1041 through a fastener; the cowl side wall panel roof mounting point 1441 located at the front side of the top of the side wall panel connects the side wall panel 144 of the cowl to the vehicle body frame C-shaped groove 1041 at the corresponding position through two interconnected "L"-shaped cowl side wall panel connection codes 1445 and fasteners 191.

[0058] Furthermore, as Figures 18-20As shown in the figure, a front mounting point 1443 of the front of the hood side wall panel 144 is provided at the front side of the hood side wall panel 144, and a front mounting point 1444 of the front of the hood side wall panel is provided at the bottom of the hood side wall panel 144. The underbody mounting point 1444 of the hood side wall panel is connected to the C-shaped groove 1041 of the vehicle body frame at the corresponding position at the bottom of the vehicle body frame 104 through the hood side wall panel connection code 1445 and the fastener 191. The hood side wall panel connection code 1445 is a slender plate-like structure, and the mounting surface at one end thereof fits at the mounting points of the hood side wall panel 144 at different positions. Then, according to its relative position with the corresponding C-shaped groove 1041 of the vehicle body frame and the surface shape of the passing mounting surface, different forms and angles of bending or splicing are performed to ensure that the mounting surface at the other end fits on the mounting surface of the corresponding C-shaped groove 1041 of the vehicle body frame for easy installation. For example, at the front mounting point of the hood side wall panel above the front side of the side wall panel, the hood side wall panel connection code 1445 is an "L" shape with two bottom edges butted; at the front mounting point of the hood side wall panel below the front side of the side wall panel, the hood side wall panel connection code 1445 is an "L" shape with one end fixed on the hood side wall panel 144, fitting the surface of the vehicle body frame 104 and extending forward longitudinally and then bending inward to fit the mounting surface of the corresponding C-shaped groove 1041 of the vehicle body frame.

[0059] Further, the underbody mounting point 1444 of the hood side wall panel is connected to the C-shaped groove 1041 of the vehicle body frame at the corresponding position through the hood side wall panel connection code 1445 and the fastener 191. Similarly, the hood side wall panel connection code 1445 has different shapes according to its mounting position and requirements. The hood side wall panel connection codes 1445 at the underbody mounting points 1444 of the head side wall panel at the front side and the middle of the bottom of the side wall panel are both "L" shaped structures, while the hood side wall panel connection code 1445 at the underbody mounting point of the head side wall panel at the rear side of the bottom of the side wall panel is a sheet-like structure without bending.

[0060] Even further, as Figures 14-17 shown, inner mounting points 1442 of the hood side wall panel are provided around the side wall panel bonding rubber molding structure 1446. The inner mounting points 1442 of the hood side wall panel are connected to the C-shaped groove 1041 of the vehicle body frame at the corresponding position on the side window opening of the vehicle body frame 104 through the hood side wall panel connection code 1445. For the hood side wall panel connection codes 1445 around the side wall panel bonding rubber molding structure 1446, one end is integrated on the inner surface of the hood side wall 144, and the other end fits the joint surface of the side wall panel bonding rubber molding structure 1446 and the vehicle body frame 104 and extends to the mounting surface of the corresponding C-shaped groove 1041 of the vehicle body frame. Similarly, the hood side wall panel connection code 1445 has different shapes according to its mounting position and requirements.

[0061] An integrated fixed connection point is adopted. The side wall panel 144 of the hood is mechanically connected to the vehicle body frame 104 through connecting plates and fasteners of various structures, and mechanical reinforcement is carried out on the bonding glue molding structure 1446 of the side wall panel and the vehicle body frame 104 on the basis of using sealant for bonding, ensuring the stability and reliability of the sealing structure.
