Technical Field

[0001] The present invention relates to the technical field of back panels, and particularly to a PET foam luggage back panel structure. Background Art

[0002] As an important storage space of a vehicle, the rationality and durability of the internal structure of the vehicle luggage have an important impact on the user experience. The vehicle luggage back panel, usually also known as the trunk partition, cover plate or guard plate, is an important part inside the vehicle trunk. The main function of the luggage back panel is to divide the trunk space into two independent upper and lower areas, facilitating the vehicle owner to separate and store items of different sizes to achieve classified management of items;

[0003] Traditional vehicle luggage back panels are mostly made of metal or ordinary plastic materials. Although the metal back panel has high strength, it is relatively heavy and prone to rust and corrosion; the ordinary plastic back panel has relatively low strength and is prone to damage when subjected to a large external force impact, bringing inconvenience to the vehicle owner; for this reason, a PET foam luggage back panel structure is proposed. Summary of the Invention
