Foldable bicycle

Abstract

The invention discloses a foldable bicycle, which comprises a bicycle rear wheel rotating assembly, wherein a part of the bicycle rear wheel rotating assembly is matched with an inward recess of a front mudguard on a bicycle front fork connected with a transverse beam; a tangent plane of a rear wheel is formed on a groove of the transverse beam, so that the rear wheel of the bicycle is fixed; or a part of the rear wheel in the rear wheel rotating assembly of the bicycle can be accommodated in the groove of the bicycle transverse beam; and one end of the transverse beam which is positioned on a joint base is set as a battery cabin. In the foldable bicycle, the fundamental principle of human engineering is combined, and every assembly is set in complete reference to the industrial standard of bicycles, so that the foldable bicycle has the characteristics of compact structure, aesthetic feeling, convenience for folding and high practicability, is safe and reliable for riding, and has the functions of an electric bicycle.

[0005] Chinese patent ZL discloses a "suitcase type folding bicycle front and rear wheel retractable device", the bicycle front fork of the device is used as the first fulcrum of the first fulcrum A rotating shaft is arranged on the rigid shell of the box body, and a second rotating shaft used as a second fulcrum on the rear fork coincides with the axle centers of the bicycle crankset and the foldable pedals and is arranged on the rigid shell of the box body. The bicycle front wheel received in the box by the first rotating shaft, the rear wheel received in the box by the second rotating shaft, the upper half of the front bracket, the folded bicycle faucet and handle connected with the upper half of the front bracket, and the front The space occupied by the lower half of the front bracket connected by the upper part of the bracket is matched with the shape and size of the inner cavity of the box; the invention maximizes the use of the space of the box, and has a compact structure, ingenious design, and the device The bicycle is easy to carry; however, because the main components of the bicycle are installed in the box, the weight of the box is objectively increased. When the bicycle is in a folded state, the hand feels heavy and not light enough; In terms of the method of putting it into the box, it adopts a rotary folding method, and both the front and rear wheels must be folded into the box, so there are many folding steps, which are difficult for ordinary people to master; Chinese patent ZL discloses a suitcase-type folding bicycle It consists of a box body, a foldable bicycle faucet and a handle that can be folded and placed in the box, a retractable bicycle faucet support tube connected with the bicycle faucet and the handle, and a bicycle front and rear wheel. The bicycle central axis is arranged on the box body. The bicycle rear wheel shaft is arranged at the rear lower part of the box body, a part of the bicycle rear wheel is exposed outside the box body, and the other part of the bicycle rear wheel is accommodated in the box body; The parts are arranged at the position of the box body, which simplifies the folding steps of the bicycle, reduces the weight of the bicycle, and makes it more convenient to carry; the bicycle with the above two structures can be known as a structure of a folding bicycle, and its folding The center is selected on the central axis of the bicycle; like this, the structure of each part of the bicycle can be considered to be reasonably arranged: obviously, the bicycle parts are arranged on the casing to form a suitcase type folding bicycle. There are still limitations, and there is still room for improvement. necessary
