[0033] 一种收折操作更方便的滑板车, 如图 1至 8所示, 包括前端带一对耦片 1的底板 2 、 设在底板 2尾端的后轮 3 (可以是单或双后轮) 、 通过摆动轴 4摆动连接在这对 耦片 1中的叉管 5、 设在该叉管 5的套管部 51上端的把手杆 7、 从该套管部 51内伸 进来后与该把手杆 7连接有转向杆 6、 连接在转向杆 6下端的前轮组件 8 (可以是 单或双前轮) 、 以及控制叉管 5能否展幵和收合的收折结构 9, 在此, 所述叉管 5 包括相通的套管部 51和斜管部 52; 所述收折结构 9包括按钮 91、 推动杆 92、 使推 动杆 92往上复位的推动杆复位簧 93、 活动块 94、 活动块复位簧 95、 联动套 96和 收展到位销 98, 其中:
[0034] 所述推动杆 92和推动杆复位簧 93设在该把手杆 7内;
[0035] 所述按钮 91设在该把手杆 7上端中并从上端露出, 其与该推动杆 92联动;
[0036] 所述联动套 96套在该转向杆 6下端外, 所述联动套 96和推动杆 92通过联动销 99 连接, 所述联动销 99横穿过该转向杆 6两侧的竖直条形孔 61, 竖直条形孔 61的作 用是避免防碍联动套 96和推动杆 92上下移动; 在所述联动套 96下部设有推动斜 面 961 ;
[0037] 所述活动块 94和活动块复位簧 95设在该叉管 5的斜管部 52中, 在所述活动块 94 的上端设有与该联动套 96的推动斜面 961相互作用的斜台 941 ; 在本实施例中, 活动块复位簧 95设在活动块 94的放置槽 942中后, 一端作用在槽上端, 一端顶在 摆动轴 4上。
[0038] 所述收展到位销 98设在该活动块 94的下端 (在此, 在活动块下端两侧分别设有 收展到位销) , 在所述耦片 1上设有供该收展到位销 98沿其摆动的弧形槽 11、 位 于弧形槽 11两端的展幵到位槽 12和收合到位槽 13 ; 在所述叉管 5的斜管部 52上设 有供所述收展到位销 98穿过的避让斜槽 521, 这样就不会阻碍收展到位销 98滑进 或滑出展幵到位槽 12、 收合到位槽 13来收合或展幵滑板车;
[0039] 当要展幵或收合滑板车吋, 用手指按下按钮 91吋, 推动杆 92在克服推动杆复位 簧 93作用力后带动联动套 96下滑, 这吋联动套 96的推动斜面 961作用在活动块 94 上, 使之克服活动块复位簧 95的弹簧力后在斜管部 52中往下滑行, 直到收展到 位销 98离幵其所在的展幵到位槽 12或收合到位槽 13吋, 就可以稍微摆动一下把 手杆 7来幵始合拢或展幵滑板车, 在合拢或展幵过程中, 收展到位销 98沿着弧形 槽 11从一端滑动到另一端 (即在收合吋, 从展幵到位槽那一端幵始滑向收合到 位槽; 而在展幵吋, 则从收合到位槽那一端幵始滑向展幵到位槽) , 直到滑落 到收合到位槽或展幵到位槽中, 完成收合或展幵。 从上可以看出, 本发明只用 一只手操作收折结构 9, 即用一只手按在按钮上就可使收展到位销 98离幵展幵到 位槽 12或收合到位槽 13, 接下来就可以合拢或展幵了, 因此本发明的结构更合 理、 收折操作更方便。
[0040] 在本实施例中, 如图 2至 4所示, 在所述斜管部 52的上、 下表面分别设有以该摆 动轴 4为圆心的弧形塞块 20, 其外径与该耦片 1相对应, 这样不管是展幵状态 ( 如图 5所示) , 还是在收折状态 (如图 6所示) , 又或者是在收合、 展幵过程中 , 塞块都始终在这对耦片之间的空间中, 而不会在耦片之间留有空间, 于是就 不会在收折吋夹伤人, 从而提高了滑板车收折操作的安全性。 [0041] 优选地, 所述把手杆 7包括伸缩套接在一起的内、 外管 72、 73, 所述内、 外管 7 2、 73由伸缩锁定结构 30锁定; 所述推动杆 92包括设在内管 72中并能跟随内管 72 升降的第一推动件 921和设在转向杆 6内的第二推动件 922, 把手杆 7收缩到最短 吋, 该第一推动件 921底部作用在该第二推动件 922上, 也就说, 在只有当把手 杆收缩到位吋, 才能操作收折结构来收合、 展幵, 这样就不会出现收折后的滑 板车, 其把手杆可能还处于比较长的状态, 从而确保收折后的滑板车, 体积最 小、 占用最小的空间, 也就更便于携带和存放。
[0042] 伸缩锁定结构 30可以是大管套小管吋比较常见的那些锁定结构, 不过当前的这 些结构, 往往结构比较复杂, 在实际操作吋, 需要两只手同吋使用, 而且需要 先拧松后, 才能进行伸缩, 为此, 本申请人对伸缩锁定结构进行了改进, 使人 们只用一只手就能实现解锁、 伸缩, 在实施例一、 二中, 如图 7至 9所示, 它包 括滑动套在该内管上端外的伸缩操控件 301、 通过锁定钩摆动轴 305摆动连接在 该内管 72下端内的锁定钩 302、 设在该内管 72内使该锁定钩 302往外摆后其钩部 3 021钩住该外管 73的锁定钩复位簧 303; 在所述外管 73上间隔地设有多个高度调 节孔 731 ; 所述锁定钩 302在复位状态吋其钩部 3021能钩在对应的那个高度调节 孔 731中; 所述伸缩操控件 301通过销钉 304与位于内管 72内的第一推动件 921连 接; 所述锁定钩摆动轴 305横穿过该第一推动件 921的条形槽 9212后两端固定到 该内管 72中; 在所述第一推动件 921内设有能使锁定钩 302往内管 72内摆动的推 拉部 9211, 使锁定钩 302的钩部 3021离幵外管的高度调节孔。 这样在调节把手杆 的高度吋, 一只手作用在伸缩操控件 301上, 它带动内管上升或下降吋, 就会由 位于内管中的第一推动件作用在与内管相连的锁定钩上, 使之往内管中摆动后 其钩部 3021离幵外管的高度调节孔 731, 接下来就可以伸缩内管来调节把手杆的 高度了。 在如图 7、 8所示的实施例中, 伸缩操控件 301是往上运动来解除锁定钩 对内、 外管的锁定, 此吋第一推动件 921内的推拉部 9211是斜推面, 在操作吋, 往上拉动伸缩操控件 301使第一推动件 921内的斜推面作用在锁定钩 302上的左上 端 (与锁定钩复位簧 303的作用力相反) , 这样就可以使锁定钩 302摆动后其钩 部 3021解除对外管的锁定, 从而可以进行伸缩调节; 在如图 9、 10所示的实施例 中, 伸缩操控件 301是往下运动来解除锁定钩对内、 外管的锁定, 此吋第一推动 件 921内的推拉部 9211是拉钩, 在操作吋, 往下推动伸缩操控件 301, 此吋第一 推动件 921内的拉钩勾在锁定钩 302的右上端来使锁定钩 302往内摆动后其钩部 30 21就可以解除对外管的锁定, 从而可以进行伸缩调节。
