一活动关节 30， 其设于该前车架 10与后车架 20间， 较佳的实施例中， 该活动 关节 30设于第一弧形段 11与前车架 10间， 且第二弧形段 21的枢接端 22与活动关节 30相连接， 该自由端 12呈可自由摆动状态， 使第一弧形段 11与第二弧形段 21可相 互靠合或张开； 且该第一弧形段 11于活动关节 30至自由端 12之间设有一座管 13， 以供座椅装设。 以及
一弹性避震块 40， 其外周缘设有一第一弧形面 41及一第二弧形面 42， 该第一 弧形面 41接合于第一弧形段 11， 且第二弧形面 42接合于第二弧形段 21， 该第一弧 形面 41与第一弧形段 11具有相同的弧形曲线， 且该第二弧形面 42与第二弧形段 21 具有相同的弧形曲线， 使该弹性避震块 40装设于第一弧形段 11与第二弧形段 21之 间； 其中， 该弹性避震块 40进一步包含：
一外层件 43， 该外层件 43贯穿设有一穿槽 431， 该第一弧形面 41与第二弧形面 42设置于其外周缘； 以及
一内层件 44， 其设于该穿槽 431内， 其中， 该外层件 43及内层件 44为硅胶弹性 体， 且该外层件 43、 穿槽 431及内层件 44的截面呈纺锤状、 椭圆状其中之一， 而该 外层件 43与内层件 44可具有相同或相异的弹性系数。
其中， 在一较佳的实施例中， 如图 5所示， 该外层件 43于第一弧形面 41与第二 弧形面 42处各设有一固定孔 432， 各固定孔 432可供以一固定元件 433分别固接于第 一弧形段 11与第二弧形段 21。 且该固定孔 432连通于穿槽 431， 且该固定元件 433为 一螺丝， 于该第一弧形段 11与第二弧形段 21上各设有一锁孔 434， 该锁孔 434内设 有一螺丝套 435， 该螺丝套 435可供螺丝螺锁固定； 再者， 该螺丝具有一尺寸大于 固定孔 432的头端， 以卡固于穿槽 431内。
明了上述本案详细结构后， 以下针对本案的动作原理逐一详细说明： 如图 3及图 5所示， 本发明安装时， 只需先将固定元件 433自外层件 43的固定孔
432由穿槽 431往向外侧（第一弧形面 41/第二弧形面 42)穿过， 再分别锁设于第一弧 形段 11与第二弧形段 21锁孔 434内的螺丝套 435， 将该外层件 43与第一弧形段 11及 第二弧形段 21相接合。 接着， 将内层件 44件往穿槽 431内塞入， 藉由外层件 43及内 层件 44的弹性变形， 使得内层件 44得以紧固于穿槽 431内， 本发明的结构及安装方 式十分简单、 容易。 更进一步地， 该内层件 44上可穿设一孔 441， 该孔 441可供与 固定元件 433的头端卡固， 以加强外层件 43及内层件 44间的卡固力量。 而当使用者 欲改变避震装置的阻尼特性时， 亦只需将内层件 44自穿槽 431施力推出， 再重新安 装具合适弹性系数的内层件 44， 即可达到改变避震装置阻尼特性的目的。
而由于座管 13设于该第一弧形段 11自活动关节 30至自由端 12之间， 当使用者 骑乘受到地面反作用力时， 该前车架 10与后车架 20间以活动关节 30为轴心， 使第 一弧形段 11与第二弧形段 21可相互靠合或张开， 并藉由第一弧形段 11与第二弧形 段 21挤压弹性避震块 40 (如图 6 ) ， 利用弹性避震块 40弹性来吸收及释放反作用 力， 达到缓冲、 吸震、 减少骑承者不适的目的。
由以上详细说明， 可使熟知本项技艺者明了本发明确实与习用的设计截然不 同， 具有相当的新颖性。 且本发明具有习用设计所无法预期的功效， 实已符合专 利核准的积极要件， 爰依法提出专利申请。
