The invention provides a top connection structure, which belongs to the technical field of rail transit and comprises a first hoisting bracket, a first profile, a second hoisting bracket, a second profile and a light stand. One side of the first hoisting bracket is provided with a first profile for accommodating wires, and the lower end is provided with a first connecting plate; one side of the second hoisting bracket is provided with a second profile, and the lower end is provided with a second connecting plate; the lamp holder is installed on the Below the first connecting plate and the second connecting plate. In the roof connection structure provided by the present invention, the first hoisting bracket and the second hoisting bracket are installed on the top of the compartment, the side roof is connected through the first hoisting bracket, the second hoisting bracket is connected to the middle roof, and the light frame for installing the light strip, The wires are accommodated by the first profile and the second profile, so that the components can be modularized and integrated, avoiding the use of secondary frames, making the connection structure on the top of the entire carriage lighter, reducing the weight of the car body, and achieving lightness of the whole vehicle Quantitative requirements.
Description
technical field [0001] The invention belongs to the technical field of rail transit, and more specifically relates to a top connection structure. Background technique [0002] In urban rail vehicles, the interior roof (middle roof and side roof), wire ducts and light strips are mainly installed in the upper area of the car, and the three need to be fixed with the car body through the internal connection profile structure to form The connection structure of the top of the carriage. [0003] When installing the interior roof, wiring ducts and light strips in the compartment, the conventional installation method is to use the secondary skeleton to hoist the profile to install on the top of the compartment, and use the secondary skeleton as the medium to hoist the interior roof, trunking and light strips, but the secondary The frame is mostly a solid square aluminum profile structure, and covers the entire top area of the car body, which increases the weight of the car body...
