It moves outward, thereby driving the middle plate to move outward, and the distance between the middle plate and the positioning plate is reduced. At the same time, the electric telescopic column extends outwards, and drives the connecting plate to move outward from the inside of the middle plate until the end of the connecting plate enters the interior of the positioning plate. The end plate, the middle plate, the connecting plate and the positioning plate form a whole, which can comprehensively protect the spokes and their sides. There are bumps and scratches, and the safety of the wheel in use is improved. Several protective covers form a plurality of arc-shaped outer plates on the outside of the wheel hub for protection, and the wheel hub is not easily damaged when it is not in use.

4. By installing the positioning plate on the outside of the hub plate, after the end of the connecting plate enters the interior of the positioning plate during operation, the limit plate at the bottom can move up under the drive of the telescopic rod and abut with the bottom of the connecting plate. Thus, the top of the connecting plate is in close contact with the top plate. The connecting plate is well fixed in the positioning plate. During use, there will be no shaking with the rotation of the wheel, and the stability is good. When the protective cover needs to be retracted, the connecting plate is retracted to the inside of the middle plate, and the middle plate is stored inside the end plate, the overall volume is reduced, the space is small, and the appearance is more beautiful.

9. The automobile wheel hub guard circle of claim 1, characterized in that, the top of tip board (5) is connected with shielding plate (22), and battery box (23) are installed at the top of shielding plate (22), and the bottom of pivot (25) is connected with the output shaft of motor (24), motor (24) and battery box (23) electric connection, and motor (24) and electronic flexible post (28) electric connection have the PLC controller, and the outside connecting rod (26) of a plurality of pivot (25) are the setting of staggering.

10. The method for installing and using the automobile hub protection ring in claim 1 is characterized by comprising the following specific steps:

the method comprises the following steps: the positioning plate (4) is arranged outside the hub plate (35), and the protective cover (3) is fixedly arranged on the hub (1); when the positioning plate (4) is installed, the bottom plate (12) at the bottom of the positioning plate faces the hub plate (35), and a screw for fixing the hub (1) penetrates through the support column (11) and the hub plate (35) by using a bolt hole (8) to be connected and fixed with a vehicle body; when the protective cover (3) is installed on the hub (1), the fixing clamp (20) at the bottom of the end plate (5) is fixedly connected with the spoke (36); the spoke (36) is clamped in the fixing clamp (20), the fastening bolt (34) is screwed to move, the end part of the fastening bolt (34) rotates on the side surface of the pressing plate (32) through the bearing (31), and then the pressing plate (32) is driven to move until the pressing plate (32) is abutted against the spoke (36);

step two: when the automobile runs, the control switch is pressed, and the motor (24) and the electric telescopic column (28) are started to run; the motor (24) drives the rotating shaft (25) to rotate, the connecting rod (26) outside the rotating shaft (25) rotates along with the rotating shaft (25), the connecting rod (26) moves outwards from the inside of the end plate (5) and further drives the middle plate (6) to move outwards, and the distance between the middle plate (6) and the positioning plate (4) is reduced; meanwhile, the electric telescopic column (28) extends outwards to drive the connecting plate (7) to move outwards from the inside of the middle plate (6) until the end part of the connecting plate (7) enters the inside of the positioning plate (4); the end plate (5), the middle plate (6), the connecting plate (7) and the positioning plate (4) form a whole, and the wheel spoke (36) and two sides of the wheel spoke are protected;

step three: after the end part of the connecting plate (7) enters the positioning plate (4), the limiting plate (13) at the bottom moves upwards under the driving of the telescopic rod (19) and is abutted against the bottom of the connecting plate (7), and the top of the connecting plate (7) is in close contact with the top plate (10); the connecting plate (7) is fixed in the positioning plate (4); when the limiting plate (13) moves upwards, the limiting plate slides upwards along the middle supporting column (11); and the end of the connecting plate (7) is abutted to the supporting column (11), when the telescopic rod (19) moves upwards, the first spring (16) generates upward thrust on the telescopic rod at the bottom, the anti-falling plate (17) is limited by the limiting ring (18) in the moving process, and the telescopic rod (19) cannot be separated from the sleeve (15).
