Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle through passage, more particularly, to a heat insulation assembly for vehicle through passage. BACKGROUND

[0002] The through passage, also known as a windscreen, is an indispensable vehicle connecting device, located at the connecting part of two carriages, and is flexible and movable. It provides passengers with a passage that can be used to pass through the vehicle at any time, safely and conveniently while realizing the relative movement of the adjacent two carriages. In order to provide passengers with a good riding experience, the through passage is required to have good heat insulation and sound insulation performance. The realization of this function mainly relies on the folding shed structure.

[0003] In the related art, in order to solve the noise problem, the existing technology with the publication number CN208198414U provides a double-layer folding shed assembly for through passage, which comprises a support assembly and a folding shed assembly. The support assembly comprises a first door frame, an upper tread plate and a second door frame. The first door frame and the second door frame are located above the upper tread plate. The first door frame and the second door frame are symmetrically distributed on both sides of the upper tread plate. The folding shed assembly comprises a bottom folding shed, an inner folding shed and an outer folding shed. The outer folding shed is fixedly connected to the first door frame. The bottom folding shed, the inner folding shed and the outer folding shed are provided to improve the sound insulation effect. The inner folding shed and the outer folding shed of the new double-layer folding shed assembly for through passage form a wave inside and outside, which can effectively reduce noise and strengthen sound insulation and heat insulation effect, meet the sound insulation and heat insulation requirements of the vehicle, and provide a comfortable riding environment. The bottom folding shed and the upper tread plate form a structure that can provide a fire barrier to protect passengers as much as possible in the event of a fire.

[0004] Although the existing technical solution in the above improves the sound insulation effect by the bottom folding shed, the inner folding shed and the outer folding shed, the existing closed air cavity formed between the inner folding shed and the outer folding shed can significantly reduce the heat transfer by conduction and convection through the low air heat conduction coefficient principle, thereby improving the heat insulation performance, but the inner and outer folding sheds will be attached due to changes in air pressure or vehicle shaking, so that the air cavity cannot always maintain an independent space, resulting in uneven and unstable heat insulation.

[0005] In view of this, we propose a heat insulation assembly for vehicle through passage. Content of the utility model
