Embodiment Construction

[0036] Figure 2a It is a schematic front view of the structure of the auxiliary side wall provided by Embodiment 1 of the present invention, Figure 2b for Figure 2a left view diagram of .

[0037] Embodiment 1 of the present invention provides an auxiliary side wall, wherein the auxiliary side wall 6 includes a plurality of hollow profiles 1 , and the plurality of hollow profiles 1 are pieced together and welded to form the auxiliary side wall 6 .

[0038] Hollow profiles can play a good role in sound insulation, heat insulation and cold protection because of the air in the hollow part. Here, the hollow profile can be made of aluminum alloy.

[0039] see Figure 2b , here, specifically, each hollow profile 1 includes two base plates 11 and a rib plate 12 sandwiched between the two base plates 11, the two base plates 11 and the rib plate 12 form a closed Hollow structure.

[0040] The hollow profile in the above implementation manner may have various specific structura...

Abstract

The invention provides an auxiliary side wall, a high-speed motor train unit body and a high-speed motor train unit. The auxiliary side wall comprises a plurality of hollow section bars and is formed by piecing the hollow section bars together by means of welding. The hollow section bars are capable of effectively achieving sound insulation and noise reduction as air is reserved at hollow positions of the hollow section bars.

Description

technical field [0001] The invention relates to mechanical structure technology, in particular to an auxiliary side wall, a car body and a high-speed EMU. Background technique [0002] At present, the doors used on the 200km / h high-speed EMUs are built-in sliding doors. Figure 1a It is a schematic diagram of the local structure of the car body in the prior art; Figure 1b for Figure 1a A-A sectional schematic diagram of ; Figure 1c for Figure 1a B-B sectional schematic diagram of . [0003] Specifically, the car body of the high-speed EMU includes a side wall 7 and an auxiliary side wall 8, the side wall 7 is provided with a through hole, a door frame 9 is installed on one side of the through hole, and the plug door is slidably arranged on the door frame 9 , and can slide along the length of the car body. The auxiliary side wall 8 is installed on the other side of the above-mentioned through hole, and cooperates with the door frame 9 to block the above-mentioned throu...
