[0028] 上述的后轮减震机构 100, 在滑板车转向吋, 支撑杆会随着压力的改变绕销轴 2 轴线相对固定架 1摆动, 以调整连接板 300的倾斜度, 进而带动踏板倾斜, 从而 提高了转向的机动性, 并确保了滑板车行走的安全性和可靠性, 及使用舒适度
[0029] 为叙述方便, 下文中所称的 "左" "右" "上" "下"与附图本身的左、 右、 上、 下方 向一致, 但并不对本实用新型的结构起限定作用。
[0030] 参见图 1和 2, 本实施例提供的后轮减震机构 100, 主要用在但不局限于滑板车 中, 该后轮减震机构 100包括固定架 1、 销轴 2、 支撑架 3和减震组件 4。
[0031] 在本实施例中, 连接板 300的前端用来连接在踏板 (图未示) 上, 其后端安装 有固定架 1, 两个后轮 200分别以可转动的方式配置在支撑架 3的两端上。 固定架 1包括基座 11和连接在基座 11底面的导向支架 12, 基座 11通过螺钉方式固定于连 接板 300, 导向支架 12包括彼此平行的两个导向板 14, 导向板 14与基座 11呈垂直 设置, 两个导向板 14之间形成有供支撑架 3中部一插入空间 15, 每个导向板 14均 具有一滑槽 13, 滑槽 13沿垂直于基座 11底面的方向延伸并贯穿于导向板 14的相 对两侧表面, 两个导向板 14的滑槽 13—一对应对齐设置。 支撑架 3的中部具有供 销轴 2的一端穿过的枢接孔 31, 销轴 2的一端穿过滑槽 13和枢接孔 31后, 将支撑 架 3连接至固定架 1上, 可以理解的是, 支撑架 3能够绕销轴 2的轴线相对固定架 1 摆动, 并销轴 2上下滑动吋相对固定架 1上下移动。
[0032] 参见图 1和 2, 在本实施例中, 为了保持支撑架 3的平衡性, 减震组件 4的数量为 但不局限于两组, 两组减震组件 4分别位于导向支架 12的左右相对两侧, 减震组 件 4能够吸收后轮 200的震动。
[0033] 具体地, 每组减震组件 4均包括固定轴 41、 紧固件 42和弹性元件 43, 固定轴 41 的上端固定在基座 11内, 紧固件 42连接至固定轴 41的下端, 紧固件 42可以为螺 母, 固定轴 41的下端形成有与紧固件 42螺纹配合的外螺纹。 弹性元件 43可以为 压簧, 弹性元件 43套设在固定轴 41上, 且弹性元件 43的两端分别抵接于基座 11 和支撑架 3, 紧固件 42抵顶在支撑架 3的底端面。 可以理解的是, 可通过拧动紧 固件 42使紧固件 42相对固定轴 41移动, 在需要较大的减震弹力吋, 可拧动紧固 件 42推动支撑架 3相对固定架 1靠近, 进而对弹性元件 43进一步地挤压, 以增加 弹性减震力; 而在需要较小的减震弹力吋, 则拧动紧固件 42使该紧固件 42朝远 离固定架 1的方向移动。
