Description
Technical field
The present invention relates to the wheel Liang Zhou parallel folds mechanism of bicycle production technical field, more particularly to bicycle.
Background technology
At present, the folding of the body portion of in the market folded bicycle can extremely be divided into greatly two kinds：(1) two-wheeled can be overlapping after folding, but
Car body hinged place locking device need to be unclamped, car body lift-off ground be folded, its shortcoming is during folding：Need certain hand
Strength and folding operation space, hand is easily made dirty during operation, operating process is longer, and corner angle are more after folding, and lift-off is needed when mobile
Ground could move；(2) on the same line, non-overlapping, its shortcoming is two-wheeled after folding：Because to make volume after vehicle frame folding
Diminish as far as possible, vehicle frame need to be divided into some segments, and use substantial amounts of hinge connection, so as to cause folding articulated elements many
More, frequent use easily causes abrasion, failure or generation potential safety hazard；Folded according to telescopic, then due to mill when using
Damage and the reason for pressure, telescopic vehicle frame is yielding, leads to not telescopic folding, and two-wheeled and same straight line is listed in after folding
On, volume and floor space are all larger, place and movement is all restricted very much.And annex fold generally use successively foldable handlebar,
The all parts such as vehicle seat, pedal, each part are designed with a locking device, and the folding for often completing a part is required for twisting
Pine and tighten locking device.Because locking device is more（As little as 4 ~ 5, up to 8 ~ 10）, operating process is longer, therefore can not reach
The purpose of all annexes foldings is completed to once-through operation.
