Abstract: Provided is a foldable rotation shaft, including: a base, a first support mechanism, and a second support mechanism. In an unfolded state, the base, the first support mechanism, and the second support mechanism are respectively configured to support a bending portion, a first portion, and a second portion of the flexible display panel. The second support mechanism is configured to cause, in a folded state, a region, proximal to the base, of the second portion to be bent into a curved shape along a direction going away from the first support mechanism. The first support mechanism is configured to cause, in the folded state, a curvature of a partial region of the first portion to be different from a curvature of the region, bent into the curved shape, of the second portion. The partial region is opposite to the region, bent into the curved shape, of the second portion.

Abstract: A support device and a foldable device. The foldable device comprises a bendable structure (102) and a support device (101). The bendable structure (102) comprises a bending portion (1021), and a first non-bending portion (1022) and a second non-bending portion (1023) respectively located on two sides of the bending portion (1021). The support device (101) comprises a first support (1011), a second support (1012), a rotating shaft support (1013), and at least one support component (1014). The first support (1011) is used to support the first non-bending portion (1022), and the second support (1012) is used to support the second non-bending portion (1023). Each support component (1014) is connected to the rotating shaft support (1013), and is further used to be connected to the bending portion (1021) to provide support. The support device (101) is used to support the entire bendable structure (102) to avoid swelling of the bending portion (1021) of the bendable structure (102), thereby ensuring the flatness of the bendable structure (102).
