A protection device, a dust removal device, a wheel rim structure and an automobile. The protection device comprises a first protection structure (1), a second protection structure (2) and a guide structure (3). The first protection structure (1) comprises first blades (11) and a first rotating ring (12), and one end of each first blade (11) is connected to the first rotating ring (12). The second protection structure (2) comprises second blades (21) and a second rotating ring (22), and one end of each second blade (21) is connected to the second rotating ring (22). The first rotating ring (12) is sleeved outside the second rotating ring (22). The guide structure (3) is arranged between the first rotating ring (12) and the second rotating ring (22). The first rotating ring (12) can rotate relative to the second rotating ring (22), so that the first blades (11) and the second blades (21) overlap or are staggered. The guide structure (3) is used for limiting the rotation travel of the first rotating ring (12) relative to the second rotating ring (22). The protection device is simple in terms of structure, and is automatically turned on according to inertia generated by means of braking, thus preventing a vehicle from the adhesion or collection of non-brake dust, such as wheel-edge dust, when the vehicle does not brake. A purely mechanical structure is used, and no additional energy is consumed.
