The invention discloses a folding frame with a magnetic damping function. The folding frame comprises a crossbeam, a front frame and a handlebar, a saddle rod is slidably connected to the rear end ofthe crossbeam, a rear fork is rotatably connected to the lower portion of the rear end of the crossbeam through a rotating device, and a control device is arranged on the crossbeam. The rotating device comprises a fluted disc shaft, bearings symmetrically arranged from the middle of the fluted disc shaft to the two sides and a middle shaft, inner rings of the bearings are in interference fit withthe fluted disc shaft, outer rings of the bearings are in interference fit with the inner side of the middle shaft, the middle shaft is sleeved with a copper sleeve, one end of the middle shaft is provided with a first end cover, and the other end of the middle shaft is provided with a second end cover. A first limiting groove is formed in the lower portion of the rear end of the crossbeam, a fixed magnet clamping groove matched with the first limiting groove is formed in the rear fork, and a magnetic damping device is arranged on the fixed magnet clamping groove. The folding frame is compactin structure, the folding thickness is greatly reduced, the overall stability is high, comfort is high, attractiveness and elegance are achieved, operation is easy and convenient, when the folding frame is applied to a vehicle with a chain, a chain wheel can be installed on a chain wheel shaft, and dual purposes of one shaft are achieved.
Description
technical field [0001] The invention relates to the technical field of vehicle frames, in particular to a folding vehicle frame with a magnetic damping function. Background technique [0002] Foldable two-wheeled vehicles are welcomed by consumers for their ease of handling and storage. The frame of the existing two-wheeled folding bike is generally rotated and folded at the girder, the structure is not compact, and the folding thickness is relatively large, because the girder is a part that is frequently stressed, and setting a turning point on the girder will reduce the overall stability of the frame and affect the appearance at the same time Spend. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technologies and provide a folding vehicle frame with a magnetic shock absorption function. [0004] In order to solve the above-mentioned technical problems, the technical solutio...
