Description

纤维复合材料车架 技术领域
本发明是与自行车的车架有关， 特别是关于一种纤维复合材料车架。 背景技术
传统的自行车车架的材质大多为铝合金， 其结构坚固但重量大。 现今自行车的设计日趋 轻量化， 因此许多自行车的车架都改以坚硬且比重较铝合金小的碳纤维复合材料制成。
前述的碳纤维复合材料车架的制造方法是将碳纤维复合材料包覆于一充气件的外表面， 待车架成型后， 再将该充气件内的气体消除， 然后再将消气后的充气件自该车架内抽出， 如 此的制造程序相当繁琐， 尤其， 车架是以数个管体连接而成， 而若欲以前述制造方法一体成 型地制造出数个相互连接的管体， 制造上又更加困难。 而且， 前述充气件即使充满气体仍稍 有软度， 因此碳纤维复合材料实际上难以相当密实地包覆于充气件。 再者， 由于碳纤维复合 材料车架是呈中空状， 若厚度过小则相当容易断裂， 而若将厚度增大则又无法兼顾轻量化的 目的。 发明内容
有鉴于上述缺失， 本发明的主要目的在于提供一种纤维复合材料车架， 其重量轻且不易 断裂， 并较容易制造， 且其纤维复合材料较容易被密实地设置。
为达成上述目的， 本发明所提供的纤维复合材料车架包含有至少一车架单元， 该车架单 元包含有二构件， 以及至少一由该二构件连接而成的杆体， 各个构件具有一由发泡材料制成 的发泡体， 以及一包覆于该发泡体外且由纤维复合材料制成的纤维复合材料外层， 且该纤维 复合材料外层具有一接合面， 该二构件是以其纤维复合材料外层的接合面相互固接， 且该二 构件的形状实质上以该二构件的接合处为中心而相互对称。
藉此， 单一车架单元即可制成车架的形状， 或者亦可由数个车架单元连接成车架。 不论 是前述何种形式， 该纤维复合材料车架的制造过程中无传统的将充气件消气及取出等程序， 因此较容易制造， 而且各个发泡体较传统的充气件坚硬， 因此纤维复合材料较容易被密实地 包覆于各个发泡体。 此外， 该纤维复合材料车架即使具有相当薄的纤维复合材料外层， 亦可 藉由这些发泡体的缓冲作用， 以及该二构件的纤维复合材料外层相接时形成的工形梁结构， 而具有不易断裂的特性， 且更有重量相当轻的优点。
有关本发明所提供的纤维复合材料车架的详细构造、 特点、 组装或使用方式， 将于后续 的实施方式详细说明中予以描述。 然而， 在本发明领域中具有通常知识者应能了解， 这些详 细说明以及实施本发明所列举的特定实施例， 仅是用于说明本发明， 并非用以限制本发明的 专利申请范围。 附图说明

申请人首先在此说明， 在以下将要介绍的实施例以及图式中， 相同的参考号码， 表示相 同或类似的组件或其结构特征。
请先参阅图 1， 本发明一第一较佳实施例所提供的纤维复合材料车架 10包含有一车架单 元 11， 该车架单元 11包含有四杆体 12， 这些杆体 12如同传统的自行车车架的前管、 上管、 下管及座管， 这些杆体 12概连接成封闭的四边形。
请参阅图 1至图 3， 该车架单元 11包含有二构件 20， 各个杆体 12皆由该二构件 20连接 而成， 换言之， 各个构件 20的形状皆如同该车架单元 11而呈封闭的四边形， 惟图 2仅显示 该二构件 20位于其中一该杆体 12的区段， 以便说明。在本实施例中，各个杆体 12呈圆柱状， 因而各个构件 20是由四个半圆柱体连接而成的形状， 但实际上并不以此为限。
各个构件 20具有一发泡体 30， 以及一包覆于该发泡体 30外的纤维复合材料外层 40， 且 该纤维复合材料外层 40具有一接合面 42。 该发泡体 30由发泡材料制成， 例如聚脲酯
(Polyurethane; 简称 PU) 或聚碳酸酯 （Polycarbonate; 简称 PC) 等等， 具有高韧性及耐 冲撞等特性。 该纤维复合材料外层 40由碳纤维、 玻璃纤维或其它聚酯纤维等复合材料制成， 具有坚硬、 比重小、 耐高温及耐腐蚀等特性， 在本实施例中以碳纤维作为说明例。 该二构件 20以其纤维复合材料外层 40的接合面 42藉由热压的方式而相互固接， 且该二构件 20的形 状实质上以该二构件 20的接合处为中心而相互对称。
藉此， 该车架 10不但重量相当轻， 且藉由发泡体 30的设置， 使得该车架 10整体成为一 实心的结构， 即使纤维复合材料外层 40相当薄， 亦可藉由发泡体 30的缓冲作用， 以及该二 构件 20的纤维复合材料外层 40接合处所形成的工形梁结构，而使得该车架 10具有不易断裂 的特性。 此外， 该纤维复合材料车架 10的制造过程中无传统的将充气件消气及取出等程序， 因此该纤维复合材料车架 10较容易制造。 而且， 各个发泡体 30较传统的充气件坚硬， 因此 纤维复合材料较容易被密实地包覆于各个发泡体 30。
前述实施例是将单一车架单元 11制成车架的形状， 然而， 本发明所提供的纤维复合材料 车架亦可包含有数个车架单元， 例如包含有四个分别形成这些杆体 12的车架单元， 亦即， 本 发明亦可将车架区分为数个车架单元， 各个车架单元先由发泡体及纤维复合材料外层所制成 的二构件连接而成， 然后， 各个车架单元再藉由热压的方式而以其纤维复合材料外层连接于 另一该车架单元的纤维复合材料外层， 进而连接成车架。
值得一提的是， 本发明将单一车架单元分成二相对称的构件， 如此设计不但可产生如前 述的工形梁结构， 使得纤维复合材料车架更为坚固， 而且更可使在发泡体外包覆纤维复合材 料的程序更容易进行且省时。
请参阅图 4至图 9， 本发明一第二较佳实施例更提供另一种纤维复合材料车架 50， 其与 前述的纤维复合材料车架 10的差异在于， 该车架 50的各构件 60的发泡体 70具有多数相交 成网格状的沟槽 71、 72， 其中包含有数个实质上沿该杆体 12纵向延伸的纵向沟槽 71， 以及 数个与纵向沟槽 71相交且环绕该发泡体 70的环形沟槽 72。在本实施例中， 各个环形沟槽 72 实质上垂直于该杆体 12的纵向 （亦即垂直于纵向沟槽 71 )， 但实际上不以此为限； 而且， 该 发泡体 70亦可仅有纵向沟槽 71或仅有环形沟槽 72。 各个构件 60的纤维复合材料外层 80包 覆于发泡体 70时， 该纤维复合材料外层 80的一部分填充于该发泡体 70的沟槽 71、 72内， 进而形成补强肋 82， 如此不但使该车架 50的结构强度更佳， 更让纤维复合材料外层 80与发 泡体 70的结合效果更好。 各个构件 60的沟槽 71、 72及补强肋 82的数量及型态并不以本实 施例所提供者为限， 只要发泡体 70设有可供纤维复合材料外层 80填入的沟槽即可达成如前 述的功效。
最后， 必须再次说明， 本发明于前揭实施例中所揭露的构成组件， 仅为举例说明， 并非 用来限制本案的范围， 其它等效组件的替代或变化， 亦应为本案申请专利范围所涵盖。
