foldable bike

Abstract

The foldable bicycle of the present invention comprises a vehicle frame, a seat cushion, a front wheel and a rear wheel, the vehicle frame comprises a front support, a vertical pipe and a rear support, and the front support comprises a first section and a second Two sections, the bottom side of the second section is pivoted to the bottom side of the first section, and the front bracket has a virtual pivot axis between the first section and the second section, so that the first section and the second section can pivot and bend relative to each other , the second section of the front bracket is also provided with a seat tube, the vertical tube is pivoted on the first section, and a front fork is extended from the vertical tube, the rear bracket is connected to the second section of the front bracket, the seat cushion is arranged on the seat tube, and the front wheel pivot It is installed on the front fork, and the rear wheel is pivoted on the rear bracket. Because the folding structure of the bicycle is simple, the bicycle can be folded very quickly.

Description

technical field [0001] The invention mainly discloses a foldable bicycle, especially a foldable bicycle with simple structure. Background technique [0002] Please refer to Taiwan Patent No. M464387 "Folding Bicycle Two-stage Quick Release Structure" patent case, which discloses a bicycle folding method. Generally, the folding method of folding bicycles is to divide the upper tube of the frame into two sections. type, and the upper tube can be folded in half along the horizontal direction, so that after the bicycle is folded, the front wheel and the rear wheel are aligned with each other in the axial direction, so as to reduce the volume of the bicycle and achieve the effect of convenient carrying and storage. [0003] However, although the bicycle using the above-mentioned folding method can reduce the length of the bicycle, it will increase the width of the bicycle. When the user is dragging the bicycle, it is very easy to bump into other pedestrians, and when carrying the...

Problems solved by technology

[0003] However, although the bicycle using the above-mentioned folding method can reduce the length of the bicycle, it will increase the width of the bicycle. When the user is dragging the bicycle, it is very easy to bump into other pedestrians, and when carrying the bicycle to take public transportation, the bicycle will It also takes up a lot of the width of the aisle, and because the handlebars for the user to tow after the bicycle is folded are not located in the middle of the bicycle, it is easy to cause the bicycle to be unevenly stressed and cause deviation during the moving process
