Description

Technical Field

[0001] The present invention relates to a turning platform, in particular to a seat turning platform. Background Art

[0002] The seat flip table is used in places where seats need to be frequently placed or hidden. The lifting function of the seat flip table can be controlled to any height within the lifting range.

[0003] Existing seat tilt platforms suffer from a number of issues, including difficulty debugging, poor positioning accuracy, and weak structural rigidity. The existing guides can only be placed on either side of the seat platform, with the drive and guide devices mounted separately. This makes it difficult to ensure precise alignment and installation and debugging. The lack of support from the central support beam causes significant deformation in the center of the seat platform, impacting positioning accuracy, leading to a high failure rate and high maintenance costs over time.
