一种有折椅功能的拉杆箱式便携折叠电动三轮车
技术领域
本发明涉及了一种折叠电动三轮车结构， 特别涉及了一种可呈现为座椅或拉杆 箱的便携折叠电动三轮车。 背景技术
当今， 电动自行车、 电动三轮车已成为大众常用的交通工具。为了便携和存放， 市场上又涌现了许许多多的折叠电动自行车、 三轮车， 但就目前来看， 这些折叠的 电动车基本上还都不具备将其携带到公交车上和火车上的合乎要求的形状和体积。
因此，亟待开发出一种便于携带进入公交车和火车的，可以折叠的电动三轮车。
发明内容 本发明的目的是提供一种可呈现为座椅或拉杆箱的便携折叠电动三轮车， 以解 决目前存在的公交、 地铁和目的地之间交通不便的问题。
本发明采用以下技术手段实现：
一种有折椅功能的拉杆箱式便携折叠电动三轮车， 包括有控制车把 10、 电动前 轮 7、 坐框基座 1、 后轮 17和折叠车架 2 ; 折叠车架 2的后端与坐框基座 1的前侧 相铰接， 折叠车架 2的前端下侧与折叠前轮基架 3相铰接； 折叠前轮基架 3前部安 装有连接钩锁件 4， 折叠前轮基架 3的下部安装有前轮叉架 5， 前轮叉架 5的上部 置有前轮扭矩传动凹件 6， 前轮叉架 5的下部安装有电动前轮 7， 电动前轮 7的中 间部分是驱动电机 701， 折叠车架 2前端的上侧与折叠车把基架 9相铰接， 折叠车 把基架 9的上部安装有控制车把 10，控制车把 10的下侧置有车把扭矩传动凸件 12， 折叠车把基架 9的前侧置有钩锁卡件 11;
当折叠成为三轮车状态时， 折叠车架 2折至坐框基座 1的前端， 控制车把 10 折叠至垂直状态， 前轮叉架 5折至垂直状态， 通过连接钩锁件 4和钩锁卡件 11 自 说 明 书
动相互扣合， 将折叠车把基架 9和折叠前轮基架 3相互固定， 同时将上述两部分与 折叠车架 2固定为一体； 前轮叉架 5上部的前轮扭矩传动凹件 6和控制车把 10下 侧的扭矩传动凸件 12相互扣合；
靠背 14下部的靠背固定折点 142与坐框基座 1的上侧相铰接， 靠背端头铰链 点 143与连杆 15的上侧相铰接； 折叠后轮架 16的后轮架上端头铰链点 161与坐框 基座 1下侧相铰接， 折叠后轮架 16下端安装有后轮 17; 折叠后轮架 16的下侧与连 杆 15下侧的连杆下端头铰链点 151相铰接； 弹力推杆 18的前端与靠背 14下部的 靠背端头铰链点 143相铰接， 弹力推杆 18的推杆后端固定点 181与坐框基座 1的 后部相铰接；
靠背 14下部的靠背固定折点 142至背端头铰链点 143之间的靠背连杆段 141、 连杆 15、 折叠后轮架 16和坐框基座 1侧面的后轮架上端头铰链点 161至靠背固定 折点 142之间的虚线段 101部分组成了一组四杆连动机构； 其中靠背 14下部靠背 固定折点 142和坐框基座 1侧面的后轮架上端头铰链点 161为固定铰接点； 折叠拉 梁 13与坐框基座 1的前侧相铰接。

前述的控制车把 10上置有电机调速转把 19。
前述的靠背 14的后侧置有反光装置 144。
本发明与现有技术相比， 具有以下明显的优势和有益效果：
由于该车可较方便地折叠成普通拉杆箱形状和体积， 所以具备了和使用者同时 乘坐公交车和火车的条件。如果采用骑行电动车， 折叠成拉杆箱， 携带同乘公交车， 再骑行电动车的方式进市里办事或工作， 而不是自驾车的方式进城， 这样， 就会大 大的减少城市拥堵和汽车尾气排放， 而且还可以大量的节约能源和资金。 并且， 当 该车折成拉杆箱状时， 体积明显减小， 同时具备了拉杆箱可拖拽的功能， 这样， 便 可以随使用者一同进入办公室、 宾馆、 商场等。 可以说， 折叠车具备始终随身携带 的功能， 比起自驾车进城既减少了丢失的机会又节省了城市中的停车位。 另外， 该 车还可以折叠成座椅状态， 从而又进一步增加了它的应用功能。 说 明 书

请参阅图 1、 图 3、 图 6所示。 靠背 14的下侧部分为左右两侧， 并分别与坐框 基座 1上部的左右两侧相铰接， 两侧完全对称， 以下所述的部分左右两侧也完全对 称， 这里仅表述一侧。
靠背 14下段的靠背固定折点 142与坐框基座 1的上侧相铰接， 靠背 14下侧端 头的靠背端头铰链点 143与连杆 15的上侧相铰接； 折叠后轮架 16上端的后轮架上 端头铰链点 161与坐框基座 1下侧相铰接， 折叠后轮架 16下端安装有后轮 17; 折 叠后轮架 16的下侧与连杆 15下侧的连杆下端头铰链点 151相铰接； 弹力推杆 18 的前端与靠背 14下部的靠背端头铰链点 143相铰接， 弹力推杆 18的推杆后端固定 点 181与坐框基座 1的后部相铰接。
靠背 14下部的靠背固定折点 142至靠背端头铰链点 143之间的靠背连杆段 141、 连杆 15、 折叠后轮架 16和坐框基座 1侧面的后轮架上端头铰链点 161至靠背固定 折点 142之间的虚线段 101等四个部分组成了一组四杆连动机构。 其中靠背 14下 部靠背固定折点 142和坐框基座 1侧面的后轮架上端头铰链点 161为固定铰接点。 当该车展开呈现三轮车状态或座椅状态时， 手搬动靠背 14折起至垂直状态， 由于 连杆 15的连动作用， 同时将折叠后轮架 16的下侧推离坐框基座 1， 从而也呈现展 开状态， 此刻， 在弹力推杆 18的推力作用下， 靠背 14和折叠后轮架 16均都稳定 地保持着这种展开状态； 当该车折叠至拉杆箱状态时， 徒手搬动靠背 14折叠至坐 框基座， 由于连杆 15的连动作用， 同时将折叠后轮架 16的下侧拉回至坐框基座 1， 此刻， 在弹力推杆 18的推力作用下， 靠背 14和折叠后轮架 16均稳定地保持着这 种与坐框基座 1的并拢状态。
折叠拉梁 13与坐框基座 1的前侧相铰接。 当折叠成拉杆箱状态时， 折叠拉梁 13折叠至坐框基座 1的前侧， 此时， 折叠拉梁 13起到拉杆箱拉梁的作用； 当折叠 成座椅状态时， 折叠拉梁 13折至坐框基座 1的下侧， 此时， 折叠拉梁 13又成为座 椅的前腿； 当折叠成运输或存放状态时， 折叠拉梁 13进一步折并于坐框基座 1， 此 时折叠拉梁 13几乎不占空间体积， 以便于运输和存放。 请参阅图 6、 图 7、 图 8。 说 明 书
当呈拉杆箱状态携带乘车时， 为了不对其他乘客造成影响， 坐框基座 1的所有 外角都进行倒角处理。 参阅图 1。
