Description

Technical Field

[0001] The utility model belongs to the technical field of luggage, and in particular relates to an integral top lining structure of a soft material luggage. Background Art

[0002] A trolley case is a bag with a trolley and wheels, which is popular because of its convenience in carrying and ample storage space. In order to ensure the overall structural strength, the top plate, back plate and bottom plate of the existing trolley cases are integrated into one structure. However, the integrated structure of the top plate, back plate and bottom plate easily leads to excessively high production costs and inconvenient installation. In addition, the overall weight of the existing trolley cases is too heavy, resulting in excessively high production costs.

[0003] In order to solve the deficiencies of the prior art, people have conducted long-term exploration and proposed various solutions.
