Technical Field

[0001] The invention relates to a novel adjustable sleeper tea table assembly for trains and a use method thereof, belonging to the technical field of railway passenger car equipment. Background Art

[0002] At present, China's railway passenger car products are developing rapidly, and people have more and more transportation options for travel. For long-distance passengers, choosing a sleeper is a good choice. The sleeper is the most direct contact interface for passengers and has an important impact on the comfort of passengers' journey. With the improvement of passengers' requirements for travel comfort and safety, the existing sleeper structure can no longer meet the needs of passengers. Sleepers with structures such as backrests and tea tables have become a new trend in the development of high-end sleepers. For example, the Chinese patent CN2020231478896 of the applicant is named a new type of tea table in the middle of a flip sleeper. The lower berth is a flip structure. The flipped back serves as the backrest of the seat to improve comfort. It can be put down as the berth surface. After converting from the sleeper state to the seat state, a tea table is provided in the middle. When the first level is opened, it rotates around the tea table axis to a horizontal position, presenting a tabletop for the left and right passengers to use together; after the second level is opened, the upper tabletop is divided into two parts, becoming two tabletops for the left and right passengers to use respectively. At the same time, the lower tabletop of the original tea table forms a new tabletop for the left and right passengers to use together, dividing the original tea table into three, and becoming three tea tables. However, the tea table has an overly complex structure, a high manufacturing cost, and cannot be freely controlled to flip over, causing inconvenience to passengers. Summary of the invention
