Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle accessories, in particular to a high-strength motorcycle rear rack. Background Art

[0002] With the improvement of people's living standards, the use of motorcycles has become more and more popular. Motorcycles are not only a means of transportation, but also a kind of leisure product for people, especially modern people. The rear of the motorcycle frame is usually equipped with a rear rack for carrying cargo. The rear rack generally consists of a rear rack body, a left connecting pipe and a right connecting pipe.

[0003] A Chinese utility model patent application numbered CN202321834253.X discloses a motorcycle rear rack structure, which relates to the technical field of motorcycle accessories. The structure comprises a rack frame, a fixed plate fixedly connected to one side of the middle of the rack frame, through-holes formed in the middle of both sides of the rack frame, and a rotating shaft fixedly connected to the lower end of each side of the fixed plate. In the utility model, two sets of widening plates are respectively provided at both ends below the fixed plate in the middle of the rack frame. When the overall load width of the rack frame needs to be widened, the two clamps are simply removed along the slots provided on both sides of the widening plates. The two widening plates are then rotated along the two rotating shafts in a direction close to the two rack frames until the limit rods and buckles provided on one side of the two widening plates pass through the two through-holes provided in the rack frame. The two buckles are then rotated so that the buckles and the two through-holes form a perpendicular angle, thereby fixing the two widening plates. At this time, the overall load width of the cargo frame is widened, making it easier for operators to check in relatively wide objects.

[0004] For example, the Chinese utility model patent application number CN202320914006.4 discloses a motorcycle rear rack structure, including a rear rack and a lock seat. The lock seat is fixed to the bottom plate of the rear rack by lock seat bolts. The front part of the rear rack is fixed to the frame by cover nuts, front fork outer gaskets, front fork inner gaskets, rear shock absorbers, and rear shock absorber inner pads. The bottom plate of the rear rack is fixed to the frame by bottom plate bolts. The structure is simple, which improves the left-right symmetry between the rear rack, seat cushion, and frame, and greatly improves the load-bearing capacity of the rear rack.

[0005] Although the existing motorcycle rear rack can meet basic usage requirements, its overall rigidity is poor. Once the rear rack is deformed due to overloading, it will lead to deformation of the entire motorcycle frame, thereby seriously affecting the overall safety of the motorcycle. Utility Model Content

[0006] The technical problem to be solved by the present invention is to provide a high-strength motorcycle rear rack in response to the above-mentioned defects of the prior art.
