Novel rail car air duct module integration structure

Abstract

The invention discloses a novel rail car air duct module integration structure. According to the technical scheme, the novel rail car air duct module integration structure comprises an air duct module, a middle top plate, a ventilating grid, a lighting device and a side top plate. The upper side of the air duct module is fixedly connected with a car body frame, the upper end of the inner side of the air duct module is fixedly connected with the middle top plate, the ventilating grid is arranged on the lower side of the middle top plate, and the outer side of the ventilating grid is fixedly connected with the air duct module. The lighting device is arranged on the lower side of the ventilating grid, and the upper end and the lower end of the lighting device are both fixedly connected with the air duct module. The side top plate is arranged on the lower side of the lighting device, the upper end of the side top plate is fixedly connected with the air duct module, the outer side of the lower end of the side top plate is fixedly connected with a side wall frame, and the side wall frame is fixedly connected with the car body frame. The air duct module, the middle top plate, the side topplate, the ventilating grid and the lighting device are installed in an integrated mode, then the air duct module is installed on the car body frame, the complexity degree of the car body structure is lowered, and the structure is easy and convenient to install and convenient to maintain.

Description

technical field [0001] The invention relates to the field of rail vehicle body structures, in particular to a novel rail vehicle air duct integration structure. Background technique [0002] The existing rail vehicle body includes modules such as car body frame, air duct, middle roof, side roof, lighting and ventilation grille. Each module needs to be installed and connected to the car body frame separately, so the car body frame needs to provide a large number of installation interfaces , the body frame is highly complex. Each module needs to be installed on the car body frame separately, and each module has its own mounting bracket or fixing piece, so there are many types of materials used, heavy weight, and a lot of space. In addition, when each module of the existing rail vehicle is installed separately, the installation of each module must eliminate the deformation of the car body, and there are many interfaces, making the installation complicated. After installation,...

[0002] The existing rail vehicle body includes modules such as car body frame, air duct, middle roof, side roof, lighting and ventilation grille. Each module needs to be installed and connected to the car body frame separately, so the car body frame needs to provide a large number of installation interfaces , the body frame is highly complex

Each module needs to be installed on the car body frame separately, and each module has its own mounting bracket or fixing piece, so there are many types of materials used, heavy weight, and a lot of space

In addition, when each module of the existing rail vehicle is installed separately, the installation of each module must eliminate the deformation of the car body, and there are many interfaces, making the installation complicated

After installation, each module affects each other. When repairing a single position, it is often necessary to dismantle adjacent components to realize it. The repair process is complicated.

[0003] The integrated module in the rail vehicle in the prior art only integrates and installs a part of the structure, and the structure is complicated and the installation and maintenance are troublesome

Patent CN 203005436 U discloses a rail vehicle top modular structure, including a main frame, a roof module, a connector module and a mounting hanger, the connector module is fixedly connected to the main frame, so the roof module is fixed to the main frame connection, the main frame is fixedly connected to the roof frame through the installation hanger, and the armrest, TV, air duct, middle roof and side roof are integrated and assembled under the car through the frame beam, and the integrated modules are unified on the car to complete the installation , although the installation interfaces and mounting seats required for each component are reduced, the integrated module does not have ventilation grilles, lighting devices, etc., and the structure of the vehicle body is relatively complicated. The entire integrated module needs to be disassembled during maintenance, which is inconvenient for maintenance
