[0066] 当所述折叠车 10处于展幵状态吋, 所述前底盘 21与后底盘 23相对平展, 所述锁 固把手 83转动至所述前底盘 21的容置槽 213中, 所述锁固把手 83的锁固部 831抵 持于所述锁固块 81的止挡部 812以止挡定位, 且所述锁固块 81的锁固凸起 813抵 持于所述锁固部 831的锁固凹口 8311, 所述盖板 70压持于所述锁固把手 83, 从而 保持所述锁固把手 83与所述锁固块 81相互抵持且位置相对固定, 保持所述前底 盘 21与后底盘 23相对平展。
[0067] 在本实施例中, 所述锁固块 81的设置数量为两个, 并在平展状态下分别设置于 所述锁固把手 83的两侧, 便于将所述锁固块 81与锁固把手 83稳定连接, 从而将 前底盘 21及后底盘 23在平展状态下以固定的平展角度相互连接, 防止前底盘 21 及后底盘 23相对转动。
[0068] 请再次参见图 4, 所述折叠车 10还设有滑块 91、 滑轨 93、 拉线 95及凸轮 97。 所 述滑块 91幵设有滑块孔 911, 所述凸轮 97置于所述滑块 91的滑块孔 911中。 在本 实施例中, 所述滑轨 93固定连接于所述连接框架 411。 所述滑块 91装设于所述滑 轨 93, 并可相对于所述滑轨 93滑动。 所述凸轮 97连接于所述座位组件 43, 并随 所述座位组件 43相对于所述滑块 91摆动。 所述拉线 95的一端固定连接于所述滑 块 91, 所述拉线 95的另一端固定连接于所述定位件 415设有定位凹口 4150的一端
[0069] 所述座位组件 43相对于所述连接定位组件 41折叠吋, 凸轮 97推动滑块 91沿所述 滑轨 93滑动, 并通过拉线 95拉动所述定位件 415, 从而使所述定位件 415远离所 述定位凹口 4150的一端脱离设置于所述后底盘 23的固定块 233。
[0070] 可以理解的是, 所述凸轮 97可固定连接于所述座位框架 431, 也可固定连接于 所述靠背连接件 435, 只需保证在所述座位组件 43相对于所述连接定位组件 41折 叠吋, 所述凸轮 97相对于所述滑块 91转动即可。 在本实施例中, 所述凸轮 97为 水滴状, 所述滑块 91的滑块孔 911呈半圆形, 凸轮 97可在所述滑块孔 911中自由 转动一定角度后抵持于所述滑块 91, 从而推动滑块 91移动。
[0071] 本发明的折叠车 10在收折状态下, 座位组件 43置于所述连接定位组件 41的的两 个连接框架 411之间, 并层叠于所述连接定位组件 41的加强支撑件 413。 所述前 底盘 21与座椅 40的加强支撑件 413分别相对于所述后底盘 23折叠并层叠设置于后 底盘 23相背的两面。 在平展状态下, 前底盘 21与后底盘 23平展, 座椅 40置于所 述后底盘 23之上。 所述座椅 40的连接定位组件 41支撑固定所述座位组件 43, 以 便使用者乘坐。 本发明的折叠车 10便于收折, 收折后的折叠车 10具有外观规整 , 且具有良好的体积缩减效果。
[0072] 以上所揭露的仅为本发明一种较佳实施例而已, 当然不能以此来限定本发明之 权利范围, 本领域普通技术人员可以理解实现上述实施例的全部或部分流程, 并依本发明权利要求所作的等同变化, 仍属于发明所涵盖的范围。
