Embodiment Construction

[0030] see figure 2 and image 3 . figure 2 A schematic diagram of a foldable bicycle 3 of the present invention according to a first embodiment is shown. image 3 A top view of the foldable bicycle 3 is shown. The foldable bicycle 3 mainly includes a front frame 32 , a rear frame 34 , a rear wheel bracket set 36 , a seat frame 38 , a seat cushion 39 , a connecting rod 40 , a handle bar 42 , a front wheel 44 and a rear wheel 46 .

[0031] For the convenience of explanation, define a reference plane P (ie figure 2 paper, perpendicular to image 3 on paper, at image 3 The position is marked with a chain line) and several pivot axes (pivot axis): the first pivot B1 (parallel to the plane P, its position is marked with the center line at figure 2 Middle), the second, third, fourth and fifth pivots B2, B3, B4, B5 (parallel to each other and perpendicular to the plane P, marked with the center line of the cross only in figure 2 Middle), the sixth pivot (45° angle with p...

Abstract

The invention provides a folding frame and a folding bicycle. The folding frame comprises a front frame, a back frame and a rear wheel bracket group; a plane, a first pivot and a second pivot are defined, wherein the first pivot is parallel to the plane, and the second pivot is vertical to the plane; the rear frame and the front frame are pivoted through the first pivot; and the rear wheel bracket group and the back frame are pivoted through the second pivot. The folding bicycle comprises the folding frame, a front wheel and a back wheel, wherein the front wheel and the front frame are pivoted, and the rear wheel and the rear wheel bracket group are pivoted. The front frame is folded to the rear frame through the first pivot, and the rear wheel bracket group rotates relative to the rear frame through the second pivot to adjust the relative positions of the rear wheel bracket group and the front frame, i.e. the relative positions of the rear wheel and the front wheel are adjusted. The invention can effectively reduce the folding space of the folding bicycle and further simplifies the folding action.

Description

technical field [0001] The invention relates to a foldable vehicle frame and a foldable bicycle. Background technique [0002] Whether it is because the global energy shortage is becoming more and more obvious, relative to the rising prices of various energy sources, or based on the promotion of environmental protection and fitness, the demand for bicycles has increased significantly. But for general families, the transportation of bicycles is always a troublesome thing, so the appearance of folding bicycles has been arranged to facilitate the transportation of general cars. However, in the current folding design, the volume of the bicycle after folding is still too large, which makes the number of bicycles transported by the car limited, and also affects the transportation of other items. [0003] see Figure 1A . Figure 1A A schematic diagram of a prior art folding bicycle 1 is shown. Bicycle 1 mainly comprises vehicle frame, front wheel 14, rear wheel 16, seat cushion ...
