The invention discloses a bicycle frame forming method, a carbon fiber bicycle frame and a bicycle, and relates to the technical field of carbon fiber bicycles. The bicycle frame forming method comprises the following steps that a spool fixing groove is formed in the outer surface of an inner core mold; placing a glass fiber spool into the spool fixing groove; winding the outer surface of the inner core mold to form a carbon fiber material layer, and enabling the carbon fiber material layer to wrap the glass fiber spool; heating and curing operation is carried out, so that the carbon fiber material layer and the glass fiber line pipe are fixed; and the inner core mold is pulled away from the cured carbon fiber material layer. Based on the method, the glass fiber spool and the frame can be formed at a time, compared with the mode that the carbon fiber spool is secondarily glued in the frame after the frame is formed, a jig used for fixing the spool during secondary gluing can be omitted, process integration and simplification are achieved, the product manufacturing time is shortened, the manufacturing cost is reduced, connection is firmer, and production efficiency is improved. And the position accuracy of the glass fiber spool can be improved.

    本发明公开了一种车架成型方法、碳纤维车架及自行车,涉及碳纤维自行车技术领域,该车架成型方法包括以下步骤:在内芯模的外表面开设线管固定槽;将玻璃纤维线管放入线管固定槽中;在内芯模的外表面卷绕形成碳纤维材料层,并令碳纤维材料层包覆玻璃纤维线管;进行加热固化操作,以使碳纤维材料层与玻璃纤维线管相固定;将内芯模从固化后的碳纤维材料层中抽离。基于该方法,玻璃纤维线管可与车架一次成型,相比于在车架成型后再将碳纤维线管二次胶合于车架内部的方式,可取消二次胶合时用于固定线管的治具,实现工艺整合简化,缩短了产品制程时间,降低了制造成本,使连接更为牢固,并可提高玻璃纤维线管的位置精准度。
