The invention provides a frame unit of a bicycle and a method of manufacturing the same. The bicycle frame unit is used for forming a bicycle frame and comprises two shell pieces and an annular supporting piece, the shell pieces are connected with each other, the annular supporting piece is combined between the two shell pieces, a combination hole is formed in the annular supporting piece, and the combination hole is configured to be matched with the outer contour of an outer column. According to the frame unit, a gap is formed between the two shell pieces and the annular supporting piece, the annular supporting piece and the two shell pieces are connected through a connecting material in the gap, the shell pieces can be designed to be thin and light, the structural strength is improved and the size is controlled through the annular supporting piece, and therefore under the condition that the weight of the frame and the manufacturing process are not excessively increased, the manufacturing cost is reduced. The problem that in the prior art, the assembling operation is affected by redundant materials generated in the jointing process is effectively solved.
本发明提供一种自行车的车架单元及其制造方法。该车架单元,用于组成自行车车架且包含两相互接合的壳件与环形支撑件,环形支撑件结合在该两壳件之间,且所述环形支撑件内设有一结合孔,该结合孔配置为匹配一外部柱的外轮廓,该车架单元于该两壳件与所述环形支撑件之间形成间隙,使接合材料于间隙中接合该环形支撑件与该两壳件,能使壳件朝薄型、轻量化设计,通过环形支撑件提高结构强度与控制尺寸,故在不过度增加车架重量与制造工序的情况下,有效改进现有技术接合过程产生的赘料会影响组装作业的问题。
