[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 1-4 The utility model provides an embodiment: an aluminum alloy wheel, including a rim 1, with retaining rings 6 fixedly connected at both ends of the outer side of the rim 1, a baffle 3 sleeved on the inside of one side of the rim 1, the width of the baffle 3 is slightly larger than the width of the retaining ring 6, and a protrusion is fixed on the side of the baffle 3 close to the rim 1, slots 8 are provided at both ends of the top and bottom of one side of the rim 1, and plug blocks 7 are slidably connected inside the two slots 8. One side of the two plug blocks 7 is fixedly connected to the top and bottom ends of one side of the baffle 3, and threaded holes 10 are provided on the opposite sides of the two plug blocks 7. Bolts 11 are threadedly connected inside the two threaded holes 10, and the other ends of the two bolts 11 respectively penetrate the inner wall of the slot 8, and the inner wall of the slot 8 is provided with a through hole for the bolts 11 to pass through.

[0030] The baffle 3 is placed on the outside of the rim 1 and the protrusion on the side wall of the baffle 3 extends into the inside of the rim 1, and the insert 7 enters the inside of the slot 8. Then the bolt 11 passes through the inner wall of the slot 8 (that is, the bolt 11 passes through the through hole) and extends into the threaded hole 10 to be tightened to fix the baffle 3, so that the baffle 3 protects the retaining ring 6 to prevent the retaining ring 6 from being deformed when the wheel hits the curb. When the baffle 3 is fixed to the rim 1, the baffle 3 will protrude a part of the side of the wheel, so that when the car is driving on a road with obstacles fixed on both sides, it can prevent the side of the tire from being scratched by obstacles, thereby extending the service life of the tire.

[0031] By increasing the width of the retaining ring 6, the fullness of the wheel can be increased, thereby improving the aesthetics of the wheel. After the baffle 3 is fixed, the part of the baffle 3 that exceeds the width of the retaining ring 6 can support the tire, thereby increasing the support area of the retaining ring 6 on the tire, making the contact between the tire and the rim 1 more stable, especially when driving at high speed or turning, which helps to improve the vehicle's handling performance. In addition, increasing the contact area between the retaining ring 6 and the tire can increase the pressure of the tire on the rim 1 shared by the retaining ring 6, thereby reducing the friction between the rim 1 and the tire.

[0032] Two sealing rings 2 are fixedly connected to the opposite sides of the two retaining rings 6. When the tire is placed on the outside of the rim 1 and inflated, the side of the tire will be in close contact with the retaining ring 6. At this time, the sealing ring 2 fixed on one side of the retaining ring 6 can seal the gap between the sidewall of the tire and the retaining ring 6, thereby increasing the sealing effect of the retaining ring 6 between the tire and the rim 1.

[0033] A hub 9 is provided inside the rim 1. The hub 9 is only installed inside the rim 1, and there is no connection between the two. A plurality of evenly distributed spokes 5 are fixedly connected to the inner side wall of the rim 1, and the other ends of the plurality of spokes 5 are fixedly connected to the outside of the hub 9. Ventilation holes are provided inside the spokes 5. The ventilation holes on the spokes 5 and the gaps between the spokes 5 can allow the flowing air to blow onto the brake pads inside the wheel, so that the air can cool the brake pads. A plurality of evenly distributed spokes 5 are fixed inside the rim 1, and the other ends of the spokes 5 are connected to the hub 9. The spokes 5 can be used to support the rim 1, thereby increasing the load-bearing capacity of the hub 9. At the same time, a plurality of evenly distributed spokes 5 can evenly disperse the weight of the tire and the hub 9, making the wheel as a whole more uniform and stable. In addition, the ventilation holes on the spokes 5 can reduce the weight of the spokes 5, thereby reducing the overall weight of the wheel, thereby improving acceleration performance and fuel efficiency.

[0034] A plurality of evenly distributed fixing holes 13 are provided on one side of the wheel hub 9. The wheel is sleeved onto the outside of the axle of the car, and the wheel rod is passed through the fixing hole 13 on the wheel hub 9. A nut is sleeved onto the outside of the screw and the nut is tightened to fix the wheel.

[0035] A groove 12 is provided on the outer periphery of one side of the hub 9, and a center cover 4 is clamped inside the groove 12. The center cover 4 is clamped into the groove 12 to protect the screw on the hub 9 for fixing the wheel, preventing the screw from rusting due to corrosion from the external environment. Covering the screw with the center cover 4 can increase the beauty of the wheel, and multiple evenly distributed spokes 5 help to improve aerodynamic characteristics and reduce wind resistance.

[0036] Working principle: Put the wheel on the outside of the axle of the car, and make the wheel rod pass through the fixing hole 13 on the wheel hub 9, put the nut on the outside of the screw and tighten the nut to fix the wheel. After the wheel is fixed, the center cover 4 can be inserted into the groove 12 to cover the screw on the wheel hub 9, thereby protecting the screw to prevent mud from contaminating the surface of the screw when the car is driving on muddy roads. Place the baffle 3 on the outside of the rim 1 and make the protrusion on the side wall of the baffle 3 extend into the inside of the rim 1, and at the same time make the insert 7 After entering the slot 8, the bolt 11 is passed through the inner wall of the slot 8 (i.e., the bolt 11 passes through the through hole) and is inserted into the threaded hole 10 to be tightened to fix the baffle 3, so that the baffle 3 protects the retaining ring 6 from deformation when the wheel hits the curb. When the baffle 3 is fixed to the rim 1, the baffle 3 protrudes from the side of the wheel, so that when the car is driving on a road with obstacles fixed on both sides, it can prevent the side of the tire from being scratched by the obstacles, thereby extending the service life of the tire. By increasing the width of the retaining ring 6, the fullness of the wheel can be increased, thereby increasing the aesthetics of the wheel. After the baffle 3 is fixed, the part of the baffle 3 that exceeds the width of the retaining ring 6 can support the tire, thereby increasing the support area of the retaining ring 6 on the tire, making the contact between the tire and the rim 1 more stable, especially when driving at high speed or turning, which helps to improve the handling performance of the vehicle. In addition, the increased contact area between the retaining ring 6 and the tire can increase the pressure shared by the retaining ring 6 on the rim 1, thereby reducing the friction between the rim 1 and the tire. When the tire is sleeved on the outside of the rim 1, the sidewall of the tire can be tightly attached to the retaining ring 6 on the side of the rim 1, and the sealing ring 2 can be used to increase the gap between the retaining ring 6 and the tire, thereby increasing the sealing effect of the retaining ring 6 between the tire and the rim 1.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
