Super thin type folding bicycle

Abstract

A front beam 1.8 in an interlayer of a rear beam 1.16 takes a folding bean axle 1.17 on the upper end of a connecting part parallel to a central axle as a center, and is inserted and folded along the rear side downwards, the lower end leads the both beams to be locked to be in an unfolded state or a folded state with a beam locking bolt 1.18, and a handle core clipping device 4.0 leads a front wheel to keep steady on the same plane where a rear wheel is positioned to lead the external circle to be tangent. A front wheel and a double ladder wheel 10.4 can move back and forth or stops, and a handle core tube is unfolded to haul three wheels to move. The pedals lead the whole body to be folded to be up to being parallel to the vehicle body with a pedal rotating device 2.0 / 3.0. A vehicle seat controlling device 7.0 made of a square tube and a handle core tube folding device 5.0 specially made of a square connector are convenient, quick, accurate, reliable, and durable and theft proof. A bottom plate device 8.0 leads the vehicle seat to flip backwards, therefore, the vehicle seat occupies no height. The contraction of a shelf occupies no length, therefore, the vehicle seat can be stored. A caliper and a force dividing device are scientific, easy to be operated, light and compact. A front fork and a rear fork made of plates are light and thin. The adaptability to the road surface is strong, and the complete vehicle is rigid and durable. The folding operation is rapid and labor saving, the vehicle can be moved with the hands, the volume is small, and the swinging does not occur, therefore, the vehicle is convenient for carrying and storage.

Description

1. Technical field [0001] The invention relates to the field of bicycles, in particular to an ultra-thin folding bicycle. 2. Background technology [0002] In prior art, following weak point is arranged: [0003] 1. Car beam: Most of them are folded horizontally in the middle. A hinge with the same width as the beam is used between the front and rear beams. There is no locking method after folding. The two parallel wheels are easy to open and swing, which is not easy to carry and store; some are vertical Folding, the folding axis is set under the locking point, the position is low, and the front and rear wheels can partially overlap obliquely. Although the projection of the outer edge is relatively short, the projection of the fork frame is enlarged, forming a situation where the bottom is short and the top is long, and there is no locking method for folding; Some call it "folding in one second", but only the overall height is reduced, and the overall length does not change...

AI Technical Summary

Problems solved by technology

[0005] 2. Pedals: The folding mechanism uses a lot of force, so it is made of heavy plastic, with a break point in the middle, the outer half slides and compresses for a while, and then folds 90° to the inner half. The remaining inner half is still very thick, and the operation steps are cumbersome

[0009] 6. Seat: The installation on the seat core tube adopts the traditional method. In order to reduce the volume as much as possible, the smaller it is, the harder it is, and the ride is not comfortable enough.

[0010] 7. Car ladders: all adopt the single-ladder diagonal bracing method to stop and stand. Although they are small and exquisite, they have a single function and poor stability, which is not beneficial to reduce the volume of the whole vehicle

[0015] 11. Convex car body: lack of necessary protection, it is easy to cause damage to public property and human body in public places
