Description

Technical Field

[0001] The present invention relates to a folding device for two-wheeled and three-wheeled vehicles, in particular to a foldable handlebar system. Background Art

[0002] At present, the known folding bicycles are composed of a foldable handlebar and a foldable frame to form a folding system. In particular, most of the folding handlebar systems are folded to one side close to the front wheel. Although this reduces the height of the entire bicycle, it significantly increases the width of the bicycle and is not conducive to the storage and transportation of the vehicle. Summary of the invention

[0003] In order to overcome the shortcomings of existing foldable vehicles that are large and inconvenient for storage after folding, the present invention provides a foldable handlebar system, which can be folded longitudinally into a roughly flat rectangle of the entire vehicle, and can stand upright with only the rear wheel and two auxiliary small wheels touching the floor, minimizing the footprint.

[0004] The technical solution adopted by the present invention to solve the technical problem is that the foldable handlebar system comprises a left handlebar, a right handlebar, a vertical tube, an A-type bracket, a base, a front fork, a frame and a handlebar harness.

[0005] The left and right handlebars are hinged to the upper end of the vertical tube through a hinge shaft, the lower end of the A-type bracket and the lower end of the vertical tube are hinged to the base through a hinge shaft respectively, the base is fixed to the upper end of the front fork vertical tube by screws, the handlebar harness is hinged to the upper end of the A-type bracket through a screw, and the vertical tube and the left and right handlebars can be loosened and clamped by opening and closing the quick-release handle of the handlebar harness, and the gears on the left and right handlebar joints can realize the linkage of the left and right handlebars.

[0006] The vertical tube, A-shaped bracket and base form a stable three-dimensional triangle. The left and right handlebars are locked with the vertical tube through the handlebar harness, thus forming a solid and reliable system. The handlebar system can be folded quickly and conveniently by simply opening the quick release of the handlebar harness. After folding, it can be neatly placed vertically on the frame, and the handlebar system can be easily and quickly unfolded by locking the quick release handle of the handlebar harness.
