Abstract

The invention discloses an efficient folding bicycle, and belongs to the technical field of bicycle structures. The bicycle comprises a front wheel part, a rear wheel part and a frame part; the framepart comprises a seat supporting rod, a first front connecting rod, a second front connecting rod, a first rear connecting rod and a second rear connecting rod, wherein the first front connecting rodand the second front connecting rod are connected with the front wheel part, the first rear connecting rod and the second rear connecting rod are connected with the seat supporting rod, a sliding groove is formed in the seat supporting rod, the rear wheel part comprises a rear wheel connecting rod connected with the seat supporting rod, a sliding rod matched with the sliding groove, and a rear wheel connecting rod used for mounting of a rear wheel, the end of the sliding rod is hinged to the rear wheel connecting rod, a hinge shaft is arranged between the first front connecting rod and the second front connecting rod, hinges are arranged between the first rear connecting rod and the first front connecting rod and between the second rear connecting rod and the second front connecting rod, during folding, the end of the sliding rod slides to the top of the sliding groove along the sliding groove, the supporting rod, the first front connecting rod and the first rear connecting rod are folded to get close to, and the second rear connecting rod and the second front connecting rod are folded to get close to. The bicycle space is reduced to the minimum, and the folding efficiency is higher.

Description

Technical field [0001] The invention relates to the technical field of bicycle structures, in particular to an efficient folding bicycle. Background technique [0002] Folding bicycles belong to a category of bicycles. Generally, a folding car is composed of a frame folding joint and a riser folding joint. By folding the frame, the front and rear wheels are folded together to reduce the length by about 45%. After being folded, the whole vehicle can be put into the folding bag and the trunk of the car. In the process of folding, the car can be folded and unfolded manually without the help of external tools. After folding, the seatpost is used as a support point to make it stand stable after folding. The folding bicycle is convenient and comfortable to carry, use, and the production technology is mature. [0003] In the design of the existing folding bicycle folding mechanism, the folding bicycle is either directly folded in the middle of the frame, and the front and rear wheels...
