Problems solved by technology

Among the aforementioned two types of frames, the structure of the integral frame is fixed. Its advantage is that it has a strong bearing capacity, but its disadvantages are: because the occupied geometric space cannot be changed, it makes the manufacturer transport, store, and Users feel inconvenient when storing and carrying
The foldable frame enables the bicycle to be folded, and because the geometric space it occupies can be changed, it is convenient to transport, store and carry. Under the relative movement, so that its stiffness and bearing capacity are greatly reduced

Embodiment Construction

[0018] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0019] Such as figure 1 As shown, the bicycle frame of the present invention comprises that the first straight bar 1 is an upper cross strut, the second straight bar 2 and the third straight bar 3 are rear oblique struts, the fourth straight bar 4 and the fifth straight bar 5 is the lower horizontal strut, the sixth straight rod 6 is the supporting rod, the seventh straight rod 7 and the eighth straight rod 8 are the front oblique struts, the first hinge member 01, the second hinge member 02, the third hinge member 03, The fourth hinge member 04 and the front riser 01.

[0020] The connection mode of the bicycle frame of the present invention is:

[0021] The front riser 01 adopts a general hinge structure to directly hinge with one end of the first straight bar 1 and one end of the eighth straight bar 8 at the upper end. The other end of the...

Abstract

A frame of bicycle with full-pivoted variable structure is disclosed. The upper end of its front vertical tube is pivoted to one ends of the 1st and 8th rods. Another end of the 1st rod is pivoted toone ends of the 2nd and 3rd rod, whose another ends are respectively pivoted to one ends of the 4th and 5th rods. Another ends of the 4th and 5th rods are respectively pivoted to both ends of the 4thpivot part. Another end of the 8th rod is pivoted to the 4th pivot part. The both ends of the 6th rod are respectively pivoted to the 4th and 1st pivot parts. The 7th rod is pivoted between the lowerend of front vertical tube and the middle of the 4th pivot part.

Description

technical field [0001] The invention relates to a bicycle frame, in particular to a variable-structure white bicycle frame. Background technique [0002] At present, there are two basic types of common bicycle frames in China: one is the overall frame, the geometric shape of the frame cannot be changed, and is generally used by ordinary bicycles; the other is a foldable frame, which forms part of the frame The rods are hinged to each other, and the geometry of the frame can be changed to achieve the purpose of folding, usually used for folding bicycles. Among the aforementioned two types of frames, the structure of the integral frame is fixed. Its advantage is that it has a strong bearing capacity, but its disadvantages are: because the occupied geometric space cannot be changed, it makes the manufacturer transport, store, and The user feels inconvenience when storing and carrying. The foldable frame enables the bicycle to be folded, and because the geometric space it occu...
