Multifunctional built-in hanging arm

Abstract

The invention relates to a multifunctional built-in hanging arm which is a strip profile, wherein a bevel edge is arranged on the section of the profile; a first flange extends out of the low end of the bevel edge; a second flange extends out of the middle part of the bevel edge; the tail end of the first flange is fixedly connected with the tail end of the second flange by a first C-shaped groove; a third flange extends out, close to the high end, of the bevel edge; a fourth flange extends out of a connecting part between the middle part of the bevel edge and the second flange; the middle upper part of the third flange is intersected with the middle part of the fourth flange; a fifth flange extends out of the tail end of the fourth flange; the tail end of the third flange is fixedly connected with the tail end of the fifth flange by a second C-shaped groove; the hanging arm further comprises a horizontal sixth flange; at least two third C-shaped grooves are formed on the lower side of the sixth flange; openings of the first C-shaped groove, the second C-shaped groove and the third C-shaped grooves are vertically downward; the third C-shaped grooves are higher than the second C-shaped groove; and the second C-shaped groove is higher than the first C-shaped groove. The hanging arm can mount various built-in components at the top of a coach simultaneously, is high in integration level, improves the mounting efficiency and reduces the weight of the coach.

Description

technical field [0001] The invention relates to a multi-functional built-in suspension arm, which is suitable for highly integrated installation of roof built-in components of intercity EMUs. Background technique [0002] According to the applicant's understanding, the interior of the existing intercity EMU compartment is usually provided with a C-shaped groove on the car body, and a connector is used to fix the interior parts and the C-shaped groove together, such as the application number 2012206530474 authorized announcement number CN202923646U in China The utility model patent uses a T-shaped slider to cooperate with a C-shaped groove, and fixes functional components on the T-shaped slider, and then connects the functional components to the interior components. [0003] However, there is a problem in the prior art that different interior components on the roof of the compartment need to be hoisted with different functional components. Connection; components such as wire...

Problems solved by technology

[0003] However, there is a problem in the prior art that different interior components on the roof of the compartment need to be hoisted with different functional components. Connection; components such as wire slots, side roofs, and light strips need to be fixedly connected to the corresponding segmented aluminum profile suspension arms, and then each segmented aluminum profile suspension arm is connected to the corresponding vehicle via the same long aluminum profile suspension arm. Body C-shaped groove fixed connection

In this way, not only are there many interfaces, complicated installation methods, difficult to adjust the installation size, and low installation efficiency, but also increase the weight of the carriage, which is not conducive to energy saving and emission reduction
