[0002] The interior design of a passenger car is in direct contact with passengers, and its aesthetics largely determines the passengers' riding experience. Therefore, users have always required that the interior design of a passenger car should keep pace with the times and have a modern aesthetic perspective.

[0003] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: most of the top plates, handrails, light strips and air grilles in the current urban rail projects are independent installation components, and they are all connected and fixed to other parts such as the car body through their own relatively independent connectors, resulting in interference during the verification process, or there is no interference during the verification process, but during the actual installation, due to installation deviations, the subsequent process cannot be installed after the previous process is installed. In addition, the top plate, handrail seat, light strip and air grille are connected to the car body through their own independent connectors, which increases the design cost and production manufacturing cost, consumes man-hours, and is prone to design errors. Once an error occurs, subsequent changes will also consume man-hours and affect the reputation of the factory. Summary of the invention

[0004] The purpose of the embodiments of the present invention is to provide an integrated structure of a passenger compartment roof of a rail vehicle, an installation method and a rail vehicle, aiming to solve the technical problem that in the current roof structure, the roof, armrest seat, light strip and air outlet grille are connected to the vehicle body through their own independent connecting parts, which is prone to interference, increases design cost and production cost, wastes man-hours, and is prone to design errors.

[0005] On the one hand, a rail vehicle passenger compartment roof integrated structure is provided, comprising:

DETAILED DESCRIPTION

[0044] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0045] Please also read Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 The rail vehicle passenger compartment ceiling integrated structure provided by the embodiment of the present invention is now described. The rail vehicle passenger compartment ceiling integrated structure comprises a ceiling 100, a decorative lamp 500, a handrail mounting profile 600 and a handrail upper half 700.

[0046] The top plate 100 is provided with ventilation holes 200 and handrail mounting holes that penetrate the top plate 100 in the thickness direction, and side beams 400 for connecting with the vehicle body 300 are respectively provided at both ends in the width direction. The decorative lamp 500 is detachably mounted on the top plate 100. The handrail bar mounting profile 600 is mounted on the back of the top plate 100, and the two ends are respectively connected to the two side beams 400. The upper half of the handrail bar 700 is mounted on the handrail bar mounting profile 600, and the lower part passes through the handrail mounting hole and extends to the bottom of the top plate 100.

[0047] In this embodiment, the decorative lamp 500 can be a downlight with a spring clip, or other lamp types that can be detachably connected to the top plate 100. The selection is made according to the use requirements and is not limited here. When a downlight with a spring clip is used, the decorative lamp 500 can be directly connected to the top plate 100 through the spring clip, and then the cables between each decorative lamp 500 are connected, and a plug is left on the side of each top plate 100 to connect with the signal line of the whole vehicle.

[0048] During assembly, the decorative lamp 500 and the upper part of the handrail 700 are first installed on the top plate 100, so that the three are assembled into an integrated structure, and then the integrated structure is hoisted to the upper part of the vehicle body 300 and installed on the roof. Specifically, when installing the upper part of the handrail 700, the upper part of the handrail 700 is first installed on the handrail mounting profile 600, the side beam 400 is installed on the top plate 100, and then the assembly of the upper part of the handrail 700 and the handrail mounting profile 600 is installed on the top plate 100. During installation, first, a mounting hole for installing the handrail is opened on the top plate 100, and then the assembly of the handrail upper part 700 and the handrail mounting profile 600 is buckled onto the top plate 100, so that the lower end of the handrail upper part 700 is inserted into the mounting hole until the two ends of the handrail mounting profile 600 are connected to the top plate 100 or the side beam 400, and then the relative positions of the handrail mounting profile 600 and the side beam 400 are fixed by fasteners.

[0049] Compared with the prior art, the integrated structure of the rail vehicle passenger compartment roof provided by the embodiment of the present invention integrates the roof 100, the decorative lamp 500, the handrail mounting profile 600 and the upper half of the handrail 700 into a modular structure, and opens a ventilation hole 200 on the roof 100. Among them, the ventilation hole 200 can be used as an air supply grille for air conditioning. Such a setting not only ensures the beautiful and atmospheric structure of the roof 100, but also reduces the process of separately installing the air supply grille when installing the roof 100, thereby improving labor efficiency. The roof 100 and the decorative lamp 500 are assembled into an integrated structure, which ensures the beauty of the overall structure of the roof 100, so that the installation of the decorative lamp 500 can be completed in the factory, reducing the on-site assembly of parts, simplifying the on-site installation process, improving the installation quality and work efficiency, and reducing the labor of workers. The upper part of the handrail rod is assembled into an integrated structure with the top plate 100 through the handrail rod mounting profile 600 and the side beam 400, so that the assembly of the upper part 700 of the handrail rod and the top plate 100 can be completed under the vehicle. Compared with the operation of first installing the top plate 100 on the roof and then installing the upper part 700 of the handrail rod on the top plate 100 in the prior art, it is convenient to install and adjust, and has good workmanship, which effectively reduces the construction workload and construction difficulty of workers, and improves labor efficiency and installation accuracy.

[0050] Furthermore, the side beam 400 is provided with an outwardly-opening plug-in interface, which is used to plug in a grille, a lampshade or a second-layer roof according to actual needs. The side beam 400 is provided with a long hole, and the roof hoisting profile 800 is provided with a C-shaped groove with an opening facing downward, so that the roof can move forward and backward. The long hole and the C-shaped groove on the roof hoisting profile 800 form a cross hole, so that the operator can adjust the front, back, left, and right positions of the roof integrated structure according to actual conditions.

[0051] Please also read Figure 6 and Figure 7As a specific embodiment of the rail vehicle passenger compartment roof integrated structure provided by the present invention, the upper half of the handrail rod 700 is slidably arranged on the handrail rod mounting profile 600 along the length direction of the handrail rod mounting profile 600.

[0052] The upper part 700 of the handrail bar is slidably connected to the handrail bar mounting profile 600, so that the relative position of the upper part 700 of the handrail bar and the handrail bar mounting profile 600 can be flexibly adjusted according to the specific position of the handrail mounting hole opened on the top plate 100, thereby further improving the convenience of installing the upper part 700 of the handrail bar.

[0053] See also Figure 6 As a specific embodiment of the integrated structure of the passenger compartment roof of a rail vehicle provided by the present invention, a first slide groove 610 extending along its length direction and opening downward is provided on the handrail rod mounting profile 600, and a first slider 620 is provided in the first slide groove 610. The upper part of the handrail rod upper half 700 is threadedly connected to the first slider 620 through a first bolt 630.

[0054] The connection relationship between the first bolt 630 and the first slider 620 has two states: a tightened state and a loose state. In the tightened state, the first bolt 630 and the first slider 620 cooperate to clamp the upper half of the handrail bar 700 and the handrail bar mounting profile 600 to fix the relative position of the two. In the loose state, the upper half of the handrail bar 700 can slide freely in the first slide groove 610.

[0055] When the upper handrail part 700 is installed on the handrail mounting profile 600, the first bolt 630 and the first slider 620 are in a loose state. After the upper handrail part 700 is inserted into the handrail mounting hole and the relative position between the upper handrail part 700 and the handrail mounting hole is adjusted, the connection relationship between the first bolt 630 and the first slider 620 is adjusted from a loose state to a tight state by rotating the bolt until the relative position between the upper handrail part 700 and the handrail mounting profile 600 is fixed.

[0056] See also Figure 7 As a specific embodiment of the integrated structure of the passenger compartment roof of a rail vehicle provided by the present invention, the bottom of the side beam 400 is connected to the roof 100, and the top of the side beam 400 is provided with a second slide groove 410 extending along its length direction and opening upward, and a second slider 420 is provided in the second slide groove 410. The handrail rod mounting profile 600 is located above the side beam 400 and is threadedly connected to the second slider 420 through a second bolt 430.

[0057] During installation, the two ends of the handrail mounting profile 600 are respectively placed on the two side beams 400, and then the handrail mounting profile 600 and the side beam 400 are connected by bolts to fix the relative position of the handrail mounting profile 600 and the side beam 400 or the top plate 100.

[0058] Please also read Figure 2 , Figure 3 and Figure 5 As a specific embodiment of the integrated structure of the rail vehicle passenger compartment roof provided by the present invention, the roof 100 includes a middle plate 110, two side plates 130 arranged on both sides of the middle plate 110, and two seam blocking plates 140 installed on the back side of the middle plate 110 and arranged on both sides of the middle plate 110.

[0059] Among them, multiple reinforcing beams 120 are arranged on the back of the middle plate 110 and the side plate 130, and one end of each seam blocking plate 140 is provided with a first connecting portion 150 for connecting to the corresponding reinforcing beam 120 located on the middle plate 110, and the other end extends to the outside of the middle plate 110 and is used to cover the gap between the middle plate 110 and the corresponding side plate 130.

[0060] The provision of the reinforcing beam 120 increases the mechanical strength of the middle plate 110 and the side plate 130 , reduces the risk of deformation of the middle plate 110 or the side plate 130 during use, and ensures the stability of the performance of each plate and a longer service life.

[0061] Specifically, the length direction of the reinforcing beam 120 is perpendicular to the length direction of the top plate 100, and the length direction of the seam blocking plate 140 is parallel to the length direction of the reinforcing beam 120. One end of each seam blocking plate 140 is connected to the reinforcing beam 120 located at the outermost end of the middle plate 110 (i.e., closest to itself), and the other end extends outside the middle plate 110.

[0062] Furthermore, the first connection portion 150 is perpendicular to the seam blocking plate 140 and is integrally formed. The reinforcing beam 120 can be made of aluminum profile.

[0063] See also Figure 5 As a specific embodiment of the rail vehicle passenger compartment roof integrated structure provided by the present invention, the top surface of the first connecting portion 150 and the top surface of the reinforcing beam 120 are on the same plane. This arrangement effectively avoids the whistling sound when the air is supplied.

[0064] See also Figure 5 As a specific embodiment of the rail vehicle passenger compartment roof integrated structure provided by the present invention, shock-absorbing pads 160 are arranged between the seam blocking plate 140 and the middle plate 110, between the seam blocking plate 140 and the side plate 130, and between the handrail mounting profile 600 and the side beam 400.

[0065] The provision of the shock-absorbing pad 160 effectively avoids hard collisions between the seam blocking plate 140 and the middle plate 110, between the seam blocking plate 140 and the side plate 130, and between the handrail mounting profile 600 and the side beam 400 during use or installation, thereby avoiding the risk of wear of the corresponding components and ensuring a longer service life of the corresponding components.

[0066] Furthermore, the shock-absorbing pad 160 can be a felt strip, a rubber pad, etc., as long as it can achieve the above functions, and is not limited here. The shock-absorbing pad 160 between the seam plate 140 and the middle plate 110, between the seam plate 140 and the side plate 130, and between the handrail bar mounting profile 600 and the side beam 400 can be made of the same material or different materials, which can be selected according to needs. For example, a felt strip can be used as the shock-absorbing pad 160 between the seam plate 140 and the middle plate 110, between the seam plate 140 and the side plate 130, and a rubber shock-absorbing strip can be used as the shock-absorbing pad 160 between the handrail bar mounting profile 600 and the side beam 400.

[0067] See also Figure 1 As a specific embodiment of the integrated structure of the passenger compartment roof of a rail vehicle provided by the present invention, ventilation holes 200 are provided on both the middle plate 110 and the side plate 130. The ventilation holes 200 are located on the periphery of the corresponding plate body and form a closed curve.

[0068] The pattern formed by the ventilation holes 200 can be set according to ventilation and aesthetic requirements, and is not limited here.

[0069] Further, the vent 200 can be enclosed in a rectangular shape, and the diameter of the vent 200 can be set as required. In addition, the vent 200 can also be set at the position where the reinforcing beam 120 is provided on the back of the top plate 100 to ensure aesthetics.

[0073] Installing the second assembly onto the first assembly to form a middle plate assembly and a side plate assembly;

[0074] The middle plate assembly and the side plate assembly are hoisted onto the roof in sequence; when hoisting the side plate assembly, the gap between the side plate 130 and the middle plate 110 is adjusted according to the deviation before installation.

[0075] In order to ensure the installation effect of the decorative lights 500, there are three separate modular plates (middle plate 110 and two side plates 130) before installation, and a modular top plate area is formed after installation on the car body 300. During installation, the middle plate 110 is installed first, and then the side plates 130 on both sides are installed, and the gap between the middle plate 110 and the side plates 130 on both sides is adjusted according to the installation deviation of the car body 300. Among them, the top plate 100, the decorative lights 500, and the upper half of the handrail 700 are purchased separately to avoid bumps and scratches during transportation. They are integrated and assembled together to form a modular component before being installed on the car body 300. During assembly, the decorative lights 500 are first integrated with the top plate 100 and the wiring is left at the edge of the top plate 100. Next, the handrail mounting profile 600 and the upper half of the handrail 700 are installed on the top plate 100 to form a modular integrated structure and hoisted as a whole.
