[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0043] like Figure 2 and Figure 3 As shown, the end plate profile provided in this embodiment of the invention includes an end plate frame 100, a top plate 200, and a bottom plate 300. The end plate frame 100 includes a first end panel 110 and a second end panel 120, which are arranged parallel to each other and have a gap between them. The first end panel 110 and the second end panel 120 form an upper end beam 140 and a lower end beam 150. The top plate 200 extends horizontally along the extension direction of the upper end beam 140 and is connected to the upper end beam 140. The bottom plate 300 extends horizontally along the extension direction of the lower end beam 150 and is connected to the lower end beam 150.

[0044] In this embodiment of the invention, the end plate profile has a hollow aluminum profile structure as the main structure of the end plate skeleton 100. The end plate skeleton 100 is arranged vertically, with the vertical direction being the height direction of the end plate skeleton 100. The thickness direction of the end plate skeleton 100 has a first end panel 110 and a second end panel 120 arranged in parallel. There is a gap between the first end panel 110 and the second end panel 120 to form a hollow skeleton structure, which realizes lightweight design. At the same time, the hollow aluminum profile structure can also ensure installation strength and rigidity.

[0045] The end plate frame 100 has an upper edge of upper beam 140 and a lower edge of lower beam 150, both of which extend in the same direction as the length of the end plate frame 100. The top plate 200 is a horizontal structure connected to the upper beam 140, and its extension direction is the same as that of the upper beam 140. The first end panel 110 and the second end panel 120 can be equipped with screw seats for end plate installation. Hangers can be welded to the top plate 200 to facilitate the overall installation of the end plate profile under the vehicle crossbeam. The bottom plate 300 is a horizontal structure connected to the lower beam 150, and its extension direction is the same as that of the lower beam 150. The bottom plate 300 can be connected to the vehicle floor.

[0046] In this embodiment, the left side of the end plate frame 100 is the first end panel 110, and the right side is the second end panel 120. A connecting plate 130 is also provided at the gap between the first end panel 110 and the second end panel 120 to connect the two end panels, which further increases the structural strength of the end plate frame 100. Moreover, the first end panel 110 and the second end panel 120 are provided with through holes so that the end plate frame 100 forms a hollow frame, which further reduces the overall weight of the end plate frame 100.

[0047] In this embodiment, the top plate 200 is divided into a first upper panel and a first lower panel. The first upper panel and the first lower panel are arranged in parallel from top to bottom, and there is also a gap between the first upper panel and the first lower panel, so that the mounting frame of other equipment can be connected to the top plate 200, thereby facilitating the integration of the end plate profile with the mounting frame. In addition, the top plate 200 is also a hollow aluminum profile, further realizing the lightweight design.

[0048] According to one embodiment of the present invention, the bottom plate 300 is located on one side of the top plate 200, and the end plate frame 100 is gradually inclined towards the bottom plate 300 from top to bottom. In this embodiment, the end plate frame 100 itself has a certain inclination angle, and the bottom plate 300 and the top plate 200 are staggered in the vertical direction, that is, the bottom plate 300 and the top plate 200 are not in the same vertical plane. Therefore, the end plate frame 100 gradually inclines towards the position of the bottom plate 300 from the upper end beam 140 to the lower end beam 150. That is, the cross-sectional shape of the end plate frame 100 perpendicular to its length direction is a plate with a certain inclination angle relative to the vertical direction, which ensures the vehicle's aerodynamic performance.

[0049] According to an end plate profile provided by the present invention, a reinforcing rib 160 is further connected between the top plate 200 and the end plate frame 100. In this embodiment, a reinforcing rib 160 is provided at the connection position between the first lower plate surface of the top plate 200 and the first end plate 110 of the end plate frame 100 to increase the connection strength and structural strength.

[0050] In this embodiment, the upper beam 140 of the end plate frame 100 is vertically arranged, and the end plate frame 100 below the upper beam 140 is inclined. The horizontal end of the reinforcing rib 160 is connected to the first lower plate surface, and the vertical end of the reinforcing rib 160 is connected to the upper beam 140.

[0051] According to one embodiment of the present invention, the first end panel 110 and the second end panel 120 are further configured with two side end beams, both of which are connected between the upper end beam 140 and the lower end beam 150. The two side end beams are arranged in an arc shape, gradually approaching each other from top to bottom. In this embodiment, the two side end beams are the first side end beam 170 and the second side end beam 180, respectively. The left edge of the overall frame structure of the end plate skeleton 100 is the first side end beam 170, and the right edge is the second side end beam 180. Thus, the first side end beam 170, the upper end beam 140, the second side end beam 180, and the lower end beam 150 are connected end to end to form the four edges of the end plate skeleton 100.

[0052] Both the first side end beam 170 and the second side end beam 180 are arc-shaped structures. The length of the lower end beam 150 is less than the length of the upper end beam 140. Therefore, the first side end beam 170 and the second side end beam 180 are arranged opposite each other and gradually bend relative to each other from top to bottom. The arc-shaped structure of the first side end beam 170 and the second side end beam 180 can be connected to a curved beam to adapt to the vehicle end interface.

[0053] According to one embodiment of the present invention, one side of the bottom plate 300 is connected to the lower end beam 150, and the other side is provided with an opening 310, which faces a direction opposite to the location of the end plate frame 100. In this embodiment, the bottom plate 300 is divided into a second upper panel and a second lower panel, which are arranged parallel to each other from top to bottom, and there is also a gap between the second upper panel and the second lower panel. When the right sides of the second upper panel and the second lower panel are both connected to the lower end beam 150, the left sides of the second upper panel and the second lower panel form an opening 310 due to the gap. The opening 310 can be a mounting interface provided to realize the connection with the bottom plate.

[0054] In this embodiment, the bottom plate 300 is a hollow aluminum profile, which enables a lightweight design. In other embodiments, the bottom plate 300 can also be configured as a mounting interface for the base plate in other forms, such as a groove.

[0055] The integrated framework provided by the present invention is described below. The integrated framework described below can be referred to in correspondence with the end plate profile described above.

[0056] like Figure 1 As shown, the integrated frame provided in this embodiment of the invention includes the end plate profile and two side beam profiles 400 as described in the above embodiment; the two side beam profiles 400 are arranged parallel to each other and respectively perpendicular to both ends of the top plate 200, the two side beam profiles 400 are connected by a connecting beam 420, and the two side beam profiles 400, the end plate profile and the connecting beam 420 enclose an installation space for the integrated installation of equipment modules.

[0057] The integrated frame of this invention forms the main frame body through end plate profiles, two side beam profiles 400, and connecting beams 420 connecting the two side beam profiles 400. The main frame body is a closed structure, and the enclosed installation space is suitable for the installation of multiple devices and brake lines, saving vehicle space and facilitating daily operation and maintenance. The integrated frame formed by the fusion of end plate profiles ensures structural strength and rigidity while maximizing the lightweighting of the frame structure.

[0058] In this embodiment, both side beam profiles 400 extend toward the direction of the first end panel 110, and the top plate 200 and the bottom plate 300 also extend toward the direction of the first end panel 110. Therefore, the common space between the left side of the first end panel 110 and the lower side of the side beam profiles 400 is the installation space.

[0059] According to one embodiment of the present invention, the side beam profile 400 has a stepped cross-sectional shape and is provided with a notch 410 and a mounting hole. In this embodiment, the side beam profile 400 has a stepped cross-sectional shape perpendicular to its length direction, that is, the side beam profile 400 is a stepped structure with a certain height and width formed by bending a plate multiple times, thereby adapting to the vehicle end side beam structure. A notch 410 and a mounting hole are provided at the lowest plate position of the side beam profile 400 to achieve connection with the vehicle body side beam and skirt.

[0060] According to one embodiment of the present invention, the integrated frame further includes a cylinder hanging plate 500 and an air supply duct 600. The cylinder hanging plate 500 is disposed in the installation space, and a first side of the cylinder hanging plate 500 is connected to the top plate 200, and a second side of the cylinder hanging plate 500 is connected to the connecting beam 420. The first side and the second side are arranged opposite to each other. The air supply duct 600 is erected on the top plate 200 and the connecting beam 420.

[0061] In this embodiment, the air cylinder hanging plate 500 and the air supply pipeline 600 can form the installation conditions for the air supply module. The air cylinder hanging plate 500 is suitable for installing the air cylinder as an air source, and the air supply pipeline 600 is connected to the air cylinder and is suitable for providing air to the braking control device. In this way, the air supply module can be integrated on the integrated frame, and after integrated installation, it can be mounted on the vehicle as a whole. This takes into account both equipment installation and pipeline installation and fixation, realizes modular design, and facilitates installation and maintenance.

[0062] In this embodiment, the air supply duct 600 can be centrally arranged according to the air circuit principle and the air circuit interface design of the air cylinder and brake control device, and a fixed mounting base is provided to install it on the integrated frame.

[0063] like Figure 4 As shown, according to an embodiment of the present invention, the air cylinder hanging plate 500 is provided with a reinforcing rib 510 perpendicular to the first side on the side opposite to the installation space. The reinforcing rib 510 divides the air cylinder hanging plate 500 into a symmetrical first plate 520 and a second plate 530. The side of the first plate 520 parallel to the reinforcing rib 510 forms a first flange 521, and the side of the second plate 530 parallel to the reinforcing rib 510 forms a second flange 531. Both the first flange 521 and the second flange 531 are formed by bending in a direction opposite to the installation space.

[0064] In this embodiment, the air cylinder hanging plate 500 is a plate-like structure with a centrally welded reinforcing rib 510 and flanged ends. The reinforcing rib 510 is flanked by a first plate 520 and a second plate 530. While meeting the requirements for installation strength and rigidity, both the first plate 520 and the second plate 530 are hollow structures, removing material and allowing for a more aesthetically pleasing design. This achieves lightweighting, and the symmetrical design of the first plate 520 and the second plate 530 ensures uniform structural strength while also enhancing aesthetics.

[0065] According to one embodiment of the present invention, the integrated frame further includes a brake control mounting bracket 700, which is disposed in the installation space and is connected to the end plate profile and the connecting beam 420. The brake control mounting bracket 700 is suitable for mounting a brake control device, and the air supply duct 600 is provided with an air supply interface adapted to the brake control device.

[0066] In this embodiment, the brake control mounting bracket 700 can form the installation conditions for the brake control device that controls the vehicle's braking system. Since the air cylinder of the vehicle's air supply module and the brake control device are arranged on the frame, the air supply pipe 600 is designed according to the air circuit principle, and thus provides the vehicle's air supply interface. This allows the air supply pipe 600, the air cylinder and the brake control device to be integrated on the integrated frame. After the whole assembly, it is independent of the vehicle and is suitable for different vehicles (motor cars, trailer cars, pantograph cars, driver's cab front and rear cars).

[0067] The air supply module and braking control device are centrally arranged, which is conducive to the design of the air supply pipeline 600 and can realize different braking functions. It also has independence at the vehicle level, and the integrated structure is highly modular.

[0068] According to one embodiment of the present invention, the integrated frame further includes a valve body integrated mounting base 800 and a power supply mounting bracket 900. The valve body integrated mounting base 800 is connected to the connecting beam 420. The power supply mounting bracket 900 is disposed in the installation space and is connected to the end plate profile, the connecting beam 420 and the brake control mounting bracket 700.

[0069] In this embodiment, the vehicle operation gates, valves, and test points are integrated on the brake control device panel, thereby facilitating daily vehicle operation and maintenance. Multiple devices, including the air cylinder, brake control device, single-phase inverter power supply, anti-slip valve, balance valve, and air supply pipeline 600, are integrated. The power supply mounting bracket 900 is suitable for installing the single-phase inverter power supply, and the valve body integrated mounting seat 800 is suitable for installing the anti-slip valve and balance valve, accommodating the installation and fixing of multiple devices and pipelines. The brake control and air cylinder connection pipelines are integrated and have reserved interfaces for vehicle connection. The gates, valves, and test points are compactly integrated on the side of the skirt panel, avoiding the problem of separate brake pipeline gate operation and brake valve arrangement in vehicles, which is inconvenient for daily operation and maintenance. This saves vehicle space and facilitates daily operation and maintenance.

[0070] The rail vehicle provided by the present invention is described below. The rail vehicle described below and the integrated framework described above can be referred to in correspondence.

[0071] The rail vehicle provided in this embodiment of the invention includes a car body and the aforementioned integrated frame. The car body includes a crossbeam; the integrated frame is disposed on the crossbeam.

[0072] The rail vehicle of this invention, after the integrated frame, various equipment, and pipelines are assembled on the ground, is directly attached to the underside of the vehicle's crossbeam via lifting points, making installation convenient. Without removing the entire integrated frame from the vehicle, the design of each equipment's installation interface allows for individual disassembly and removal, facilitating equipment inspection and maintenance.

[0073] 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.
