Description

一种三折叠电动自行车 一、技术领域
本发明涉及一种交通工具，特别是涉及一种三折叠电动自行车。
二、背景技术
折叠电动车折叠电动自行车，英文名字miniBike，是可以折叠的一种电动车，通过折叠后使车辆尺寸更小，便于存放。一般分为3种方式，横向，纵向，和M型。一般折叠车有车架折叠关节和立管折叠关节构成。通过车架折叠，将前后两轮对折在一起，可减少45％左右的长度。整车在折叠后可放入登机箱和折叠包内，以及汽车的后备箱。然而现在的折叠电动车多为两折叠结构，折叠之后还是比较大，搬运不方便，并且电动折叠自行车的电瓶体型较大、不易搬运、性能不佳，且电路线材大多裸露在车架上，非常繁乱也不是十分安全。如今经过检索，发现专利“201720890916.8-一种折叠自行车”中提及一种三折叠的自行车，其易于搬运、折叠之后占地更小，因此，在此基础上，我方提出一种具有优秀的电瓶性能，易于搬运，电路线路不裸露在车架上，更加安全的新式电动自行车三折叠结构。
三、发明内容
为了克服现有交通工具的不足之处，本发明提供了一种三折叠电动自行车。
本发明的技术方案是这样实现的。
本方案的一种三折叠电动自行车，包括前轮、后轮、前挡泥板、后挡泥板和连接成一体的前三角架和后三角架，所述前三角架包括呈三角形连接的主管、支管和中管，所述后三角架包括呈三角形连接的后上叉、后下叉和中叉，所述主管靠近前轮的位置设置有折叠扣，所述前三角架与后三角架之间通过转轴和连接件连接，所述折叠扣将主管分为电池仓和控制仓，所述电池仓内部设置有贴合电池仓形状的电池盒，所述电池盒内设置有电池组，所述控制仓内部设置有控制器，所述前轮轮轴处设置有电动机，所述电动机与控制器之间电连接，所述控制器与电池盒内的电池组之间电连接。
所述电池仓开口处设置有电池盖，所述控制仓开口处设置有控制盖，所述电池盖与电池盒固定连接，所述电池盖上设置有插簧，所述电池盖上设置有充电输入口，所述插簧、充电输入口均与电池盒内的电池组电连接；
所述控制盖上设置有与插簧配合使用的插片，该插片与控制器电连接。
所述电池盒内电池组的电池架构为18650电芯3.65V两并十串结构。
所述电池盒顶端设置有用于保护电池组电路的双层锂电保护电路。
本发明的有益之处在于：该车体结构简单，可实现三折叠功能，体积更小，方便安置，同时电池组结构合理，性能优秀，电路连接简单，不需在车架上布线，更加安全。
四、附图说明
图1为本发明的结构示意图。
图2为本发明的电池组结构示意图。
图3为本发明的电池组结构放大(正向)示意图。
图4为本发明的电池组结构放大(反向)示意图。
五、具体实施方式
下面结合附图对本发明的具体实施方式做出简要说明。
如图所示的一种三折叠电动自行车，包括前轮、后轮、前挡泥板、后挡泥板和连接成一体的前三角架和后三角架，所述前三角架包括呈三角形连接的主管1、支管2和中管3，所述后三角架包括呈三角形连接的后上叉4、后下叉5和中叉6，所述主管1靠近前轮的位置设置有折叠扣7，所述前三角架与后三角架之间通过转轴8和连接件9连接，所述折叠扣7将主管1分为电池仓和控制仓，所述电池仓内部设置有贴合电池仓形状的电池盒10，所述电池盒10内设置有电池组，所述控制仓内部设置有控制器11，所述前轮轮轴处设置有电动机16，所述电动机16与控制器11之间电连接，所述控制器11与电池盒10内的电池组之间电连接。
所述电池仓开口处设置有电池盖12，所述控制仓开口处设置有控制盖13， 所述电池盖12与电池盒10固定连接，所述电池盖12上设置有插簧14，所述电池盖12上设置有充电输入口17，所述插簧14、充电输入口17均与电池盒10内的电池组电连接；
所述控制盖13上设置有与插簧14配合使用的插片15，该插片15与控制器11电连接。
所述电池盒10内电池组的电池架构为18650电芯3.65V两并十串结构。
所述电池盒10顶端设置有用于保护电池组电路的双层锂电保护电路。
本实例的工作过程：在使用该发明时，通过折叠扣7、转轴8和连接件9实现前三角支架、后三角支架的三折叠结构，便于放置和携带，体积更加轻便。折叠扣7打开时，主管1实现折叠动作，此时插簧14和插片15分开，电池盒10内的电池组停止供电，控制器11电路断开；当主管1展开，插簧14余插片15插入式连接，关闭折叠扣7，车辆电池组与控制器11、电动机16电路闭合，车辆整体具有电动能力，通过该方式实现整体电路的开闭，可以避免电路裸露在车架上，延长线路使用寿命，提高使用安全性。电池盒10内电池组的电池架构为18650电芯3.65V两并十串结构，得到36.5V的和两并输出的最高电压和最大电流，有效提高电池组的性能。同时，当需要进行充电时，可以直接打开折叠扣7折叠主管1，通过充电输入口17向电池盒10内的电池组进行充电，充电输入口17为DC2.1充电输入端子，充电效果极佳，也可以将电池盖12和电池盒10拉出，进行单独充电，更加快捷方便。
以上对本发明的一个实施例进行了详细说明，但所述内容仅为本发明的较佳实施例，不能被认为用于限定本发明的实施范围。凡依本发明申请范围所作的均等变化与改进等，均应仍归属于本发明的专利涵盖范围之内。
