一种交通工具折叠的锁定机构 一种交通工具折叠的锁定机构
技术领域
本实用新型属于折叠交通工具配件领域，具体涉及一种交通工具折叠的锁定机构。
背景技术
随着人们生活水平的提高，个性、时尚、健康、环保的生活理念开始深入人心，时尚又环保的交通工具受到越来越多人的追捧，折叠后体积小重量轻，手提折叠交通工具上下楼梯、驾车、乘公交车或地铁出行等都十分方便。
现有的可折叠的自行车或电动车，其折叠方式都较为简单，通常在两节车架管前轮方向之间设置一折叠关节，通过折叠关节将车架横向对折，折叠后车辆体积仍然较大，而且该种折叠机构只是将两节车架管进行简单的枢接，由其构成的折叠交通工具架构极不稳定，行车安全得不到保障，而且这种对车身进行简单折叠的代步车，操作步骤繁琐，仍需进一步改进。
折叠交通工具的折叠锁定机构尤为重要，影响到车辆的结构稳定性，现有技术的折叠式交通工具已经具有便于折叠的折叠机构，还需要加入简单有效的锁定机构，使得折叠式交通工具折叠过程简化的同时，其折叠后结构稳定，驾驶安全系数提高，并且不会影响车辆的折叠体积。
发明内容
为了克服上述技术缺陷，本实用新型要解决的技术问题是：设计一种交通工具折叠的锁定机构，实现折叠状态和展开状态的锁定与解锁，而且能够实现多级别、多角度的锁定与解锁。
要解决上述技术问题所采用的技术方案为：设计一种交通工具折叠的锁定机构，其特征在于，折叠轴设置销孔，轴套设置弹销，销孔与弹销相适配，所述弹销设置解锁离合， 折叠轴设置多个销孔， 所述解锁离合为拉手，所述解锁离合包括拉线，拉线一端连接弹销，另一端连接脚踏板或手动开合器，所述弹销设置于后轮架的轴套，其折叠轴对应弹销设置销孔 ，所述后轮架包括左右轮架，相应的左右轮架的轴套分别设置弹销，其折叠轴对应弹销设置销孔 ，所述弹销设置于踏板轴套，其折叠轴对应设置销孔， 所述弹销设置于前把架的轴套，其折叠轴设置销孔 ，所述弹销包括一弹簧。
应用本实用新型所具有的有益效果包括，该交通工具折叠的锁定机构，能够实现折叠状态和展开状态的锁定与解锁，而且能够实现多级别、多角度的锁定与解锁。实现过程主要依靠折叠轴与轴套的相互配合，方便快捷，结构简单，高效好用。
锁定部位选择在折叠轴，避免增加额外的装置，不会增大折叠后的整体体积，而且锁定后结构稳定，安装简单方便，易于操控。折叠轴设置销孔，轴套设置弹销，销孔与弹销相适配，不会影响轴与轴套配合的流畅性，所述弹销设置解锁离合，通过解锁离合解开轴与轴套的锁定。
折叠轴设置多个销孔，弹销依次进入各个销孔时，可以在预设的折叠角度自由锁定，多级设置增加了缓冲，避免了两折叠部位激烈碰撞，要解开锁定时按下解锁离合即可。而按下解锁离合一直不松开时，折叠轴套即可绕轴自由运动。
所述解锁离合为拉手，可以直接扳动拉手操控解锁；所述解锁离合包括拉线，拉线一端连接弹销，另一端连接脚踏板或手动开合器，使用拉线的解锁方式，解锁离合的设置位置可以任意选择，可以跟其他操纵柄或脚踏装置配合使用，在踩下脚踏板或拉动手动开合器时一并解锁，实现'一个动作多种用途'。
所述弹销包括一弹簧，当弹销转动到轴上销孔位置时，在弹簧的作用下可以直接自动弹入销孔内，轴套的转动被自动锁定。因此，折叠轴上可以在不同的部位根据需要分设两个销孔，一个折叠状态锁定的销孔，一个展开状态锁定的销孔，当折叠到位时弹销自动弹入折叠状态锁定的销孔，实现折叠自动锁定；操纵解锁离合解开锁定后，当展开到位时，弹销自动弹入展开状态锁定的销孔，实现展开自动锁定。
该结构可以结合应用到折叠交通工具的各个折叠关节，具体的， 所述弹销设置于后轮架的轴套，其折叠轴对应弹销设置销孔 ；所述后轮架包括左右轮架，相应的左右轮架的轴套分别设置弹销，其折叠轴对应弹销设置销孔 ；所述弹销设置于踏板轴套，其折叠轴对应设置销孔； 所述弹销设置于前把架的轴套，其折叠轴设置销孔。

具体实施方式
如图所示， 一种交通工具折叠的锁定机构，其特征在于，折叠轴 1 设置销孔 2 ，轴套 3 设置弹销 4 ，销孔 2 与弹销 4 相适配，所述弹销 4 设置解锁离合， 折叠轴 1 设置多个销孔 2 ， 所述解锁离合为拉手，所述解锁离合包括拉线 9 ，拉线 9 一端连接弹销 4 ，另一端连接脚踏板 5 或手动开合器，所述弹销 4 设置于后轮架 10 的轴套，其折叠轴 1 对应弹销 4 设置销孔 2 ，所述后轮架10包括左右轮架，相应的左右轮架的轴套3分别设置弹销4，其折叠轴1对应弹销4设置销孔2 ，所述弹销 4 设置于踏板 8 轴套，其折叠轴 1 对应设置销孔 2 ， 所述弹销4设置于前把架7的轴套3，其折叠轴1设置销孔2 ，所述弹销 4 包括一弹簧 6 。
该交通工具折叠的锁定机构，能够实现折叠状态和展开状态的锁定与解锁，而且能够实现多级别、多角度的锁定与解锁。实现过程主要依靠折叠轴 1 与轴套 3 的相互配合，方便快捷，结构简单，高效好用。
锁定部位选择在折叠轴 1 ，避免增加额外的装置，不会增大折叠后的整体体积，而且锁定后结构稳定，安装简单方便，易于操控。折叠轴 1 设置销孔 2 ，轴套 3 设置弹销 4 ，销孔与 2 弹销 4 相适配，不会影响轴与轴套配合的流畅性，所述弹销 4 设置解锁离合，通过解锁离合解开轴与轴套的锁定。
折叠轴 1 设置多个销孔 2 ，弹销 4 依次进入各个销孔 2 时，可以在预设的折叠角度自由锁定，多级设置增加了缓冲，避免了两折叠部位激烈碰撞，要解开锁定时按下解锁离合即可。而按下解锁离合一直不松开时，折叠轴套即可绕轴自由运动。
所述解锁离合为拉手，可以直接扳动拉手操控解锁；替换方案，所述解锁离合包括拉线 9 ，拉线 9 一端连接弹销 4 ，另一端连接脚踏板 5 或手动开合器，使用拉线的解锁方式，解锁离合的设置位置可以任意选择，可以跟其他操纵柄或脚踏装置配合使用，在踩下脚踏板 5 或拉动手动开合器时一并解锁，实现'一个动作多种用途'。
所述弹销 4 包括一弹簧 6 ，当弹销 4 转动到轴上销孔 2 位置时，在弹簧 6 的作用下可以直接自动弹入销孔 2 内，轴套 3 的转动被自动锁定。因此，折叠轴 1 上可以在不同的部位根据需要分设两个销孔，一个折叠状态锁定的销孔，一个展开状态锁定的销孔，当折叠到位时弹销 4 自动弹入折叠状态锁定的销孔，实现折叠自动锁定；操纵解锁离合解开锁定后，当展开到位时，弹销 4 自动弹入展开状态锁定的销孔，实现展开自动锁定。
该结构可以结合应用到折叠交通工具的各个折叠关节，具体的，实施例 1 ， 所述弹销 4 设置于后轮架 10 的轴套，其折叠轴对应弹销 4 设置销孔 2 。
下面介绍折叠轴1设置两个销孔的实施过程， 分设两个销孔，一个折叠状态锁定的销孔，一个展开状态锁定的销孔。 折叠状态时按下解锁离合，弹销4从销孔内脱出，伸展后轮架10，轴套3绕折叠轴1转动，展开完毕时弹销4恰好转动到轴上另一销孔位置，弹入销孔自动锁定；需折叠时，再次按下解锁离合，弹销4被解锁离合从销孔2内拉出，后轮架10带动轴套3得以绕轴继续运动，折叠到位时，弹销4恰好弹入销孔自动锁定。
销孔2设置多个时，多级别多角度的锁定过程简单，在本实施例中不再赘述。
实施例2，所述后轮架10包括左轮架11和右轮架12，相应的左右轮架的轴套3分别设置弹销4，其折叠轴1对应弹销4设置销孔2 。左右轮架在展开时合并在一起，折叠时分立在折叠轴的两侧，以便后轮可以分立在前轮两侧。因此折叠轴可以分设四个销孔 2 ，在中点位置设置两个展开锁定孔，在两个端点位置分别设置折叠锁定孔。
实施例 3 ，所述弹销 4 设置于踏板 8 的轴套，其折叠轴 1 对应设置销孔 2 ； 所述弹销4设置于前把架7的轴套，其折叠轴设置销孔2。前把架7与踏板8的轴套3共用一个折叠轴1，前把架7的轴套位置居中，踏板8的轴套在前把架7轴套的两侧，销孔2的位置和数量可以对应轴套3设置。
需要指出的是，上述实施方式仅是本实用新型优选的实施例，对于本技术领域的普通技术人员来说，在符合本实用新型工作原理的前提下，任何等同或相似的替换均落入本实用新型的保护范围。
