Description

Technical Field

[0001] This application relates to the technical field of rail trains, and specifically, to a top integrated device for a train. Background Art

[0002] The roof area of urban rail vehicles mainly consists of the middle roof, side roof, air duct, ventilation grille, and light strip, and at the same time, equipment such as handrail mounts, smoke detectors, and cameras are installed. In order to simplify the installation structure and improve the installation efficiency in the assembly workshop, the components in the roof area are designed in an integrated and modular manner to adapt to various passenger interface styles of trackless vehicles.

[0003] Currently, a secondary skeleton is first hoisted on the vehicle body through fasteners at the top of urban rail vehicles. The air duct, secondary skeleton, side roof, middle roof, light strip, and ventilation grille at the top are all installed separately in sequence to achieve the top functions.

[0004] Components such as the air duct, middle roof, side roof, light strip, and ventilation grille request installation interfaces from the secondary skeleton according to requirements, and each component is then hoisted on the secondary skeleton through fasteners in sequence. The secondary skeleton designs the profile section according to the installation requirements of each part.

[0005] The secondary skeleton is connected to each component. The upper end of the secondary skeleton is connected to the vehicle body and the angle code of the air duct using fasteners, and a chute is designed at the bottom to connect to the air duct, light strip, and side roof.

[0006] The above-mentioned roof area of urban rail vehicles has the following disadvantages:

[0007] (1) Many components and great assembly difficulty

[0008] When assembling the top, it is necessary to first hoist the secondary skeleton, and then install the air duct, middle roof, ventilation grille, light strip, side roof, etc. in sequence. There are many installation parts, and it is difficult to adjust the gaps between the roof and the roof, and between the roof and the light strip.

[0009] (2) Complex process flow

[0010] Due to the large number of installation interfaces, the installation process is complex, with high requirements for the operating skills of workers. It is easy to accumulate errors in the last process, making it difficult to adjust the gaps, which affects the aesthetics of the passenger interface. In addition, there are also high requirements for tooling tools. Due to the many assembly processes, the assembly efficiency is low, the labor cost is high, and the vehicle production cycle is long.

[0011] (3) Poor environmental protection and single expression form of the middle roof

[0012] The middle top is made of aluminum plates, aluminum honeycombs or fiberglass materials with surface painting at most, and the environmental protection of surface painting treatment is poor. If different pattern effects are to be presented on the top, the middle top needs to be processed twice. Different-shaped through holes are processed on the middle top, and then lamps are installed at the positions of the through holes on the middle top, and the process is complex. If multiple patterns are to be achieved, the manufacturing difficulty is great and the cost is high.

[0013] Therefore, there are problems in the installation of the top plate of traditional rail vehicles, such as many top-mounted components, great assembly difficulty, complex assembly process, and great adjustment difficulty between components in the top area, which are technical problems that need to be solved urgently by those skilled in the art.

[0014] The above information disclosed in the background art is only used to strengthen the understanding of the background of the present application, so it may contain information on the prior art that is not known to those of ordinary skill in the art. Summary of the Invention

[0015] The embodiment of the present application provides a top integrated device for a train to solve the technical problems of many top-mounted components and great assembly difficulty in the installation of the top plate of traditional rail vehicles.

[0016] The embodiment of the application provides a top integrated device for a train, including:

[0017] A plurality of middle modules, which are assembled by a top plate skeleton, a middle top, an air duct, a handrail and a light strip, and are pre-assembled under the train to form middle modules;

[0018] One middle module corresponds to two side top modules, and return air grilles and lamp shades are formed on the side top modules, and the side top modules are pre-assembled under the train; both sides of the middle module are respectively connected to the two side top modules, and the other sides of the side top modules are respectively connected to the side walls on both sides of the train.

[0019] Due to the adoption of the above technical solutions, the embodiment of the present application has the following technical effects:

[0020] The top integrated device of the embodiment of the present application, each middle module is assembled by a top plate skeleton, an air duct, an armrest, a middle top and a light strip, and the middle module is pre-assembled under the train; similarly, each side top module 2 is also a side top module pre-assembled under the train. After the middle module and the side top module are pre-assembled under the train, the middle module 1 is assembled with the train body above the train, and then the side top module is connected to the middle module and the side wall of the train above the train. In this way, the process of pre-assembling under the train does not need to occupy the space of the train body, so that pre-assembly can be carried out with the help of various suitable tools in a space suitable for pre-assembly (such as an assembly workshop, etc.); it is also possible to complete the pre-assembly of the middle module and the side top module in advance before the mass production or assembly of the car body is completed; then, the middle module and the side top module are installed in the car body of the train, so that the overall assembly of the train is shorter. The top integrated device of the embodiment of the present application has a high degree of integration, is convenient to install, and has high installation efficiency.

[0055] In order to make the technical solutions and advantages in the embodiments of the present application clearer and more understandable, the following further describes the exemplary embodiments of the present application in detail 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.

[0056] Embodiment 1

[0057] As Figure 1 shown, the top integrated device of the train in the embodiment of the present application includes:

[0058] A plurality of middle modules 1, which are assembled by a roof plate skeleton, a middle top, an air duct, an armrest and a light strip, and are pre-assembled under the train to form the middle module;

[0059] One middle module corresponds to two side top modules 2. An air return grille and a lamp shade are formed on the side top module, and the side top module 2 is pre-assembled under the train; both sides of the middle module 1 are respectively connected to the two side top modules 2, and the other sides of the side top modules are respectively connected to the side walls on both sides of the train.

[0060] For the top integrated device in the embodiment of the present application, each middle module is assembled by a top plate skeleton, an air duct, a handrail, a middle top, and a light strip, and the middle module is pre-assembled under the train; similarly, each side top module 2 is also a side top module pre-assembled under the train. After the middle module and the side top module are pre-assembled under the train, the middle module 1 and the train body are assembled above the train, and then the side top module, the middle module, and the side wall of the train are connected above the train. In this way, the process of pre-assembling under the train does not need to occupy the space of the train body, enabling pre-assembly to be carried out with the help of various suitable tools in a space suitable for pre-assembly (such as an assembly workshop, etc.); it is also possible to complete the pre-assembly of the middle module and the side top module in advance before the mass production or assembly of the car body is completed; then, the middle module and the side top module are installed inside the train body, making the overall assembly of the train shorter. The top integrated device in the embodiment of the present application has a high degree of integration, is convenient to install, and has high installation efficiency.

[0061] During implementation, as Figure 2 , Figure 3 , Figure 5-1 , Figure 5-2 , Figure 5-3 shown, the top plate skeleton is the installation foundation of the top integrated device; the top plate skeleton includes grille profiles 11;

[0062] The cross-section of the grille profile has three first grille chambers 11-1, a second grille chamber 11-2, and a third grille chamber 11-3 arranged horizontally;

[0063] Among them, the second grille chamber 11-2 is rectangular, the upper top of the second grille chamber has a grille air inlet 111 for docking with the air duct, and the lower bottom of the second grille chamber has a grille air outlet 112 for blowing air into the train car;

[0064] The first grille chamber 11-1 is rectangular, and the upper top of the grille profile 11 has a grille middle top mounting flange 113 extending out of the first grille chamber; among them, the grille middle top mounting flange 113 is used for mounting the middle top of the top integrated device;

[0065] The third grille chamber 11-3 is a right trapezoid, and a grille top inclined chute 114 is provided on the hypotenuse of the third grille chamber; the lower bottom of the third grille chamber has a grille side top mounting flange 115.

[0066] The three chambers of the grille profile, the first grille chamber 11-1, the second grille chamber 11-2, and the third grille chamber 11-3 arranged horizontally, divide the cross-section of the grille profile into three parts, making the grille profile have greater strength and not easily deformed; it also reserves space for setting the installation structure in different regions.

[0067] During implementation, as Figure 5-2 shown, the grille profile 11 has two grille crossbeam installation and positioning interfaces 116 and an installation and positioning interface 118 for nut sliders.

[0068] During implementation, as Figure 4-1 、 Figure 4-2 、 Figure 6-1 、 Figure 6-2 shown, the top plate skeleton further includes:

[0069] A skeleton crossbeam 12, the outer top of the skeleton crossbeam has two long-through skeleton crossbeam outer top installation interfaces 121, the bottom surface has two long-through skeleton crossbeam inner top installation interfaces 122, and each of the two side surfaces has a long-through skeleton crossbeam side installation interface 123;

[0070] Skeleton crossbeam hanging codes 13, both ends of the outer top of each skeleton crossbeam 12 are installed with the skeleton crossbeam hanging codes 13 through two skeleton crossbeam outer top installation interfaces 121; among them, the skeleton crossbeam hanging codes 13 are used to connect the middle module as a whole to the inner top of the train body;

[0071] Among them, the skeleton crossbeam 12 is placed at the grille crossbeam installation and positioning interface 116 and is connected through a connecting piece. The skeleton crossbeam 12 and the grille profile 11 are also connected through a connecting piece, the grille top inclined chute 114, and the end of the skeleton crossbeam outer top installation interface 121.

[0072] The skeleton crossbeam hanging codes 13 realize the connection between the entire middle module 1 and the inner top of the train body, so that the connection with the train is very few and the installation on the train is less.

[0073] The grille crossbeam installation and positioning interface 116 defines the installation position of the skeleton crossbeam 12, making the installation position of the skeleton crossbeam standardized and facilitating the installation by installers.

[0074] Both ends of the skeleton crossbeam 12 and two grille profiles 11 are connected through a connecting piece, the grille top inclined chute 114, and the skeleton crossbeam outer top installation interface 121. The middle part of the skeleton crossbeam 12 is respectively connected to the tops of the two grille profiles 11 through the grille crossbeam installation and positioning interface 116 and a connecting piece, making the installation of the skeleton crossbeam 12 and the two grille profiles 11 stable and reliable.

[0075] During implementation, as Figure 8-1 、Figure 8-2 As shown, there are two air ducts 15, each located above the grille profile;

[0076] The two sides of the air duct 15 are connected with the L-shaped connecting ears 151, fasteners and the outer top mounting interface 121 of the skeleton beam to achieve the fixation of the air duct.

[0077] The grid crossbeam installation positioning interface 116 defines the installation position of the frame crossbeam 12 , so that the installation position of the frame crossbeam is standardized, which is convenient for installation personnel.

[0078] In implementation, such as Figure 7-1 , Figure 7-2 As shown, the lower bottom of the first grille chamber has a through hole for handrails, the upper top of the first grille chamber has a handrail installation interface, and the side of the first grille chamber has a handrail installation window 119;

[0079] The top of the handrail 16 passes through the handrail through hole, and is connected with a handrail installation interface, a frame beam inner top installation interface 122 and a fastener to achieve the installation of the handrail, the grille profile and the frame beam. The handrail installation window 119 is used by the installer to install the handrail;

[0080] The handrail 16 and the frame beam hanger 13 are installed back to back.

[0081] In this way, the installation of the handrail, the grille profile 11 and the skeleton cross beam 12 is conveniently achieved.

[0082] The handrail is installed on the frame beam 12 through the grille profile 11. The frame beam hanger 13 installed with the vehicle body is located above the frame beam 12, which can ensure the installation strength of the handrail. The grille profile provides a handrail installation interface and a handrail installation window 119 for the handrail installation seat, ensuring the operating space.

[0083] Specifically, the armrest mounting seat is provided with an oblong hole, which is connected with a T-bolt in the inner top mounting interface 122 of the skeleton cross beam. The armrest mounting seat can be adjusted in both the vehicle length and the vehicle width.

[0084] In implementation, such as Figure 9-1 , Figure 9-2 , Figure 10-1 , Figure 10-2 As shown, the two sides of the middle top 14 are provided with a plurality of slider nuts 141;

[0085] The middle top 14 and the grille profile 11 are connected via the slider nut 141 and the nut slider installation positioning interface 118;

[0086] Among them, the slider nut 141 can slide within a preset range along the length direction of the middle top on the installation and positioning interface 118 for the nut slider, and the movable range in the width direction of the middle top is extremely small.

[0087] The slider nut 141 and the installation and positioning interface 118 for the nut slider cooperate to enable the middle top 14 to move relative to the grille profile 11 along the length direction of the middle top, reducing the requirements for the manufacturing precision of the middle top 14 and the grille profile 11 and reducing the manufacturing cost; there is a space for moderate adjustment during installation, facilitating installation.

[0088] During implementation, such as Figure 10-1 , Figure 10-2 , Figure 10-3 , Figure 11 , Figure 12 shown, the middle top includes a middle top main body 142 and a middle top lamp module 143;

[0089] The middle top lamp module 143 is installed at the position of the middle top lamp module installation window reserved on the middle top main body 142 through fasteners;

[0090] The middle module further includes a hidden light strip 17, which is installed at the grille middle top installation flange 113 and the grille side top installation flange 115.

[0091] In order to improve the riding experience, hidden light strips 17 are integrally installed on both sides of the grille profile with bolts. When installing the side top module later, the upper flanging of the side top can hide the hidden light strip 17, and only the light of the hidden light strip 17 will be shown when the lighting is turned on after the side top module 2 is installed.

[0092] During implementation, as shown in Figure 12 , 13-1 , Figure 13-2 shown, a side top hinge 21 is fixed on the upper side of the side top module, and the side top module 2 and the grille side top installation flange 115 are fixedly connected through the side top hinge 21;

[0093] The lower side of the side top module 2 is unlockably connected to the side wall of the train through a lock.

[0094] In this way, the lock and the side top hinge 21 cooperate. After the lock is unlocked, the side top module 2 can rotate with the axis of the side top hinge 21 as the axis, and the side top can rotate towards the middle of the car body, facilitating maintenance.

[0095] During implementation, as shown in Figure 13-1 , Figure 13-2 shown, the side top module 2 further includes:

[0096] Side top light strip;

[0097] On one side of the side-top module facing the ground of the train, there is an air return hole 23, and on the lower side of the side-top module, there is also a light strip cavity 24, and the side-top light strip is fixed in the light strip cavity 24.

[0098] Specifically, the top plate skeleton consists of a skeleton cross beam 12 and a grille profile 11 to form a frame structure through stainless steel fasteners. The frame structure of the top plate skeleton has high stability, high stiffness and strength, and can meet the requirements of hoisting. A stainless steel skeleton cross beam lifting code 13 is installed on the skeleton cross beam 12, and the skeleton cross beam lifting code 13 is connected to the vehicle body chute through a slider bolt to hoist the entire top integrated device.

[0099] Specifically, the skeleton cross beam is an aluminum profile, and the outer top mounting interface 121, the inner top mounting interface 122, and the side mounting interface 123 of the skeleton cross beam are T-shaped chutes, and T-shaped bolts are installed in the chutes for installing the stainless steel skeleton cross beam lifting code 13 and connecting the grille profile 11.

[0100] Specifically, the grille profile is an aluminum profile, with a grille air inlet 111 on the upper top and a grille air outlet 112 on the lower bottom; the grille profile also provides mounting holes for the side-top module 2 and the installation of the hidden light strip, and provides through holes for the armrest 16, armrest mounting interfaces and armrest mounting windows. Two vertical ribs are arranged inside the grille profile, realizing the partition setting method of the first grille chamber, the second grille chamber, and the third grille chamber. The second grille chamber has the function of ventilation and will not leak air to the first grille chamber and the third grille chamber, and the first grille chamber and the third grille chamber can also be used for the installation of other components.

[0101] Specifically, as shown in the figure, the main material of the air duct 15 is an aluminum foil composite board with a thickness of 10 mm, and the partition inside the air duct is made of aluminum sheet, and a sound-absorbing material is adhered at the partition. Sound-absorbing materials are provided in local areas inside the air duct 15. The air duct 15 is connected to the skeleton cross beam 12 using T-shaped bolts to ensure that the air duct is tightly pressed against the grille profile. The air ducts are connected to each other using flanges to ensure the airtightness of the air ducts.

[0102] Specifically, there are two installation schemes for the middle top 14:

[0103] Scheme 1: The entire middle top 14 is a square lamp, consisting of a lamp body, a profile and a lampshade, and is installed in the middle of the grille profile, combining the passenger interface and lighting functions. The load-bearing structure of a part of the lamp body of the middle top 14 is an aluminum honeycomb board, and the light-emitting board, plug and wires are installed on the aluminum honeycomb board. The lampshade is a polycarbonate board. The lamp body and the lampshade form the entire lamp module through the profile. The lampshade is inserted into the profile, and the lamp body is connected to the profile using screws. The entire lamp module is connected to the grille through bolts. Since the middle top 14 is a lampshade, different patterns and lighting color effects can be presented according to customer needs by pasting a light-shielding material on the back of the lampshade.

[0104] Solution 2: The middle ceiling main body 142 is a perforated aluminum plate, and the middle ceiling lamp module 143 is an annular light strip. The middle ceiling lamp module 143 is integrated at the installation holes reserved on the perforated aluminum plate of the middle ceiling main body 142. The annular light strip is press-fitted on the back of the middle ceiling main body 142 with screws, so that the annular light strip is closely attached to the back of the middle ceiling main body 142.

[0105] To increase the illumination, two lighting light strips are added between the middle ceiling lamp module 143 and the grille profile 11 on the middle ceiling main body 142. The slide nut 141 and the nut slide of the middle ceiling main body 142 are connected by the installation positioning interface 118. The slide nut 141 can slide and adjust in the vehicle length direction and is limited in the vehicle width direction and will not come off or separate. At the same time, it is convenient to screw in the screws from bottom to top for fixing the roof panel.

[0106] Both sides of the middle ceiling main body 142 provide slide nuts for lighting light strips for installing the lighting light strips. After the middle ceiling main body 142 is installed, the lighting light strips can be installed, and the lamp cover is installed through the card slot of the lighting light strip profile. The back of the middle ceiling main body 142 also has a camera installation interface and can integrally install a camera.

[0107] Specifically, as Figure 12 、 Figure 13-1 shown, the side ceiling module 2 and the grille side ceiling installation flange 115 are fixedly connected by the side ceiling hinge 21, and the lower side of the side ceiling module 2 is unlockably connected to the side wall of the train through a lock.

[0108] The side ceiling module 2 can be opened by more than 90° to meet the maintenance of the electrical components inside the side ceiling module 2. A small turned edge with a height of 20 mm is designed on the upper side of the side ceiling module 2 to block the side ceiling hinge 21 and the invisible light strip 17. The height spacing from the grille profile 11 is 16.5 mm, which can ensure the blocking of the invisible light strip.

[0109] The side ceiling module 2 is formed by welding two aluminum profiles, and a light strip cavity 24 is designed at the connection with the side wall. The lighting light source board is installed in the light strip cavity.

[0110] An air return hole 23 is provided on one side of the side ceiling module facing the ground of the train. Fins for blocking the connection position with the side wall are provided on the lower side of the side ceiling module, which ensures the function and does not expose the internal structure of the side ceiling module. A side ceiling hinge 21 is designed at the connection with the grille profile, which ensures the coaxiality and installation accuracy of the side ceiling hinge 21 on the same roof panel module 2.

[0111] A chute is designed on the back of the side ceiling module 2, which functions as a reinforcing rib and at the same time provides installation interfaces for electrical components (including dynamic maps, speakers, and smoke alarms). The electrical components and the side ceiling module 2 are pre-assembled under the vehicle and modularly installed on the vehicle, which improves the assembly efficiency.

[0112] The top integrated device of the train of the present application has the following technical effects:

[0113] 1. Through modular and integrated design, the top integrated device of the train of the present application is designed to have functions of ventilation, lighting, passenger interface decoration, handrails, and integrated installation of lighting and cameras. The roof skeleton, air duct, middle roof, and handrails are pre-assembled under the train body and loaded onto the vehicle in a modular form. Only the skeleton crossbeam hanging codes are used to install the device on the train body. Compared with the structure in the background art where each part and functional component are assembled in sequence, the installation process is reduced, the installation process flow is simplified, the top assembly time is greatly shortened, and a total of about 122 man-hours are saved for the top installation.

[0114] 2. Since the top integrated device of the train of the present application is installed modularly, the internal components of the integrated components (i.e., the middle module and the side roof module) have been assembled before being loaded onto the vehicle. During installation, only the errors and gaps between the middle modules and the side roof modules need to be adjusted, and there is no need to adjust the gaps and errors between each component in sequence, which improves the main line assembly efficiency and shortens the vehicle manufacturing cycle. Since the above components are not supplied integrally, the procurement form remains unchanged, and the procurement products can continue to use the suppliers of mature components.

[0115] 3. Using square lights as the middle roof, which takes into account both internal lighting and passenger interface decoration functions. The lamp shade is made of polycarbonate board material, and a light-shielding material can be pasted inside the lamp shade. Different patterns can be designed according to the needs of the owner, with a wide selection, simple manufacturing process, and low production cost. The middle roof no longer uses the painting process, making the interior of the passenger compartment more environmentally friendly and improving the comfort of the interior decoration.
