参图 10所示， 本发明的电动自行车还包括车架 100、 分别位于 车架 100前方和后方的前轮和后轮（未图示）、 设于车架 100前方的 车头组件 20、设于车架 100后方的后轮组件 300以及连接于车架 100 上的驻车机构 400。 参图 10至图 12所示， 车架 100包括支撑梁 110、 侧支架 120以 及座位支架 130， 支撑梁 110、 侧支架 120以及座位支架 130的组装 使得车架整体呈摇篮式。
支撑梁 110设置为两个，分别为位于同一面内的第一支撑梁和第 二支撑梁， 每一个支撑梁 110为金属材质制成， 其顶端沿纵长方向形 成有凹槽 111， 使得支撑梁 110的截面呈凹字形。 每一个支撑梁 110 包括矩形的平板部 112、 自平板部 112—端弯折的第一折弯部 113以 及自平板部 112另一端弯折的第二折弯部 114， 第一弯折部 113和第 二弯折部 114位于平板部 112的同一侧，且第一弯折部 113和第二弯 折部 114与平板部 112形成一凹形的 口，两个支撑梁 110背向设置， 凹口面向相反方向。 在两平板部 112之间设有一金属轴 14, 两第一 折弯部 113之间通过弧形的连接臂 150连接。
侧支架 120对称设于支撑梁 110的左右两侧，每个侧支架 120大 致呈 "L" 形， 包括位于支撑梁 110下方的水平杆 121以及大致与水 平杆 121垂直的垂直杆 122， 水平杆 121与支撑梁 110的第二折弯部 114固定连接， 垂直杆 122通过三角形的固定件 16固定连接于支撑 梁 110的第一折弯部 113; 座位支架 130固定连接于支撑梁 110的第 二折弯部 114上方，包括用以承担人体重量的底座支架 131以及用以 抵靠人体后背的靠背支架 132， 底座支架 131和靠背支架 132垂直。 底座支架 131 的前端通过第一支撑臂 1311 固定于平板部 112, 底座 支架 131的后端通过第二支撑臂 1321 固定于第二折弯部 114的后端 并向下延伸与水平杆 121固定连接。
本发明的车架 100通过支撑梁 110、侧支架 120以及座位支架 130 的连接， 使得车架 100的整体呈摇篮式， 驾驶者在行驶中更加舒适。 同时由于支撑梁 110采用凹字形金属材料制成， 强度较大， 可以承受 较大的压力和撞击力， 大大提高了车架 100的坚固度。
参图 12所示， 固定件 16用以固定侧支架 120和支撑梁 110， 包 括用以收容垂直杆 122的收容槽 161以及用以连接支撑梁 110的延伸 部 162。 当电动自行车受到撞击时， 固定件 16将外力传递至支撑梁 110， 由于支撑梁 110比较坚固， 可有效抵挡外部的受力， 避免电动 自行车较大的变形， 进而保护驾驶者。
参图 11和图 13所示， 水平杆 121上还可固定安装有脚踏板 17， 脚 方并用以支撑踏板 171的若干支撑肋 173 , 支撑肋 173之间相互平行且 垂直于踏板 171和水平杆 121。 踏板 171靠水平杆一侧向下垂直弯折有 弯折部 1711， 所述支撑肋 173贴近水平杆 121—侧设置为可与水平杆 121相配合的弧形，所述弯折部 1711和所述支撑肋 173之间形成有可固 定水平杆 121的收容部 172。
综上所述， 以上仅为本发明的较佳实施例而已， 不应以此限制本 发明的范围，即凡是依本发明权利要求书及发明说明书内容所作的简 单的等效变化与修饰， 皆应仍属本发明专利涵盖的范围内。
