Description

Technical Field

[0001] This utility model belongs to the field of seat cup holder technology, and relates to a child seat cup holder device for rail transit. Background Technology

[0002] In the context of rail transit, existing child seat cup holders suffer from insufficient expandability and lack of storage capacity. Insufficient expandability means these cup holders cannot accommodate beverage containers of different sizes or shapes, which is particularly limiting in the face of varying passenger needs. The inability to store cup holders results in them occupying unnecessary space during off-peak hours or when child seats are not in use, affecting the tidiness of the carriage interior and passenger movement. These shortcomings stem from a failure to fully consider the unique operating environment of rail transit and the diverse needs of passengers during the design phase, as well as a neglect of space utilization efficiency.

[0003] Conventional solutions include adding adjustable cup holder designs to accommodate containers of different sizes, and designing foldable or retractable cup holder structures to reduce space occupation when not in use. However, these methods have drawbacks, such as increased structural complexity, potentially leading to higher costs and increased maintenance difficulties. Adjustable cup holders may loosen or break under frequent use, while foldable or retractable structures may suffer reliability issues due to mechanical failures. Therefore, there is an urgent need for a child seat cup holder device for rail transit that addresses these problems. Utility Model Content
