STEERING ANGLE LIMITING MECHANISM, AND VEHICLE STEERING SYSTEM AND VEHICLE HAVING SAME

A rotation angle limiting mechanism and a vehicle steering system and a vehicle having same are provided. The rotation angle limiting mechanism (100) includes: a turntable (1), where at least one fitting structure (11) is arranged on the turntable (1); and a moving member (2), where a first limiting structure and a second limiting structure are arranged on the moving member (2); the turntable (1) rotates and drives the moving member (1) to move so that the fitting structure (11) abuts against one of the first limiting structure and the second limiting structure; the turntable (1) is at a first extreme position when the fitting structure (11) abuts against the first limiting structure; and the turntable (1) is at a second extreme position when the fitting structure (11) abuts against the second limiting structure.
