Abstract
A bicycle frame unit for constructing a bicycle frame has two half casing parts and an annular supporting element. The annular supporting element is connected between the half casing parts and has a connecting hole for matching an outer contour of an external post. A gap is formed between the half casing parts and the annular supporting element, and a connecting material fills the gap and connects the half casing parts and the annular supporting element. A manufacturing method of the bicycle frame unit is also provided.
Claims18
A bicycle frame unit for constructing a bicycle frame, the bicycle frame unit comprising:
- two half casing parts connected to each other along a connecting direction and being substantially symmetrical;
- and
- at least one annular supporting element connected between the two half casing parts and having
- a connecting hole formed therein and configured for matching an outer contour of an external post;
- wherein the bicycle frame unit has at least one gap formed between the two half casing parts and the at least one annular supporting element and filled with a connecting material.
A manufacturing method of a bicycle frame unit comprising the following steps:
- a casing forming step, molding one or more sheets into two half casing parts being substantially symmetrical and configured to abut against each other along a connecting direction;
- an abutting step, abutting the two half casing parts along the connecting direction and placing at least one annular supporting element between the two half casing parts to form at least one gap between the two half casing parts and the at least one annular supporting element;
- and
- a connecting step, connecting the two half casing parts via a connecting means and filling the at least one gap with a connecting material so as to finish a bicycle frame unit.
A bicycle frame unit for constructing a bicycle frame, the bicycle frame unit comprising:
- two half casing parts connected to each other along a connecting direction and being substantially symmetrical;
- and
- each half casing part having a tube-shaped upper portion and an asymmetrical lower portion along a direction perpendicular to the connecting direction, wherein said lower portion has a greater volume to contain a bike component than the tube-shaped upper portion, wherein said tube shaped upper portion has a volume to contain the other bike component to directly support a rider's weight.
