Description

一种多连杆排轮底座及其应用 技术领域
[0001] 本发明属于户外运动设备领域， 具体涉及一种多连杆排轮底座， 此外本发明还 涉及该排轮底座在多种运动设备上的应用。
背景技术
[0002] 随着人们生活品质的提高， 越来越多的年轻人会尝试并热衷于户外运动， 如轮 滑、 滑板、 滑板车等， 既能锻炼身体， 又能达到很好的社交目的。 在轮滑鞋、 滑板、 滑板车这类户外运动设备中， 都通过轮子底座与地面接触， 达到运动目 的。 我们原先设计的连杆结构也只能机械的上下运动， 因此这类运动可以在不 平的路面上进行， 但是原先的设计没有全方位转向能力， 产品结构适应能力和 舒适度不强。
[0003] 目前， 绝大多数的轮子底座都为固定式安装结构或连杆结构， 在遇到有障碍物 或有坑坑洼洼的起伏路面时， 原先的设计也具有一定的越野能力， 但连杆之间 只能简单的上下运动， 不能全方位转动， 经过复杂路面时， 有的轮子会悬空， 固定支架和上部产品也不能全方位转向， 轮子不能全部附着在地面上， 舒适度 和安全性设计上是有不足的。
技术问题
[0004] 此外， 出于安全平缓的通过起伏路面的目的， 5见有产品底座中的轮子也有设计 成可以上下升降的结构， 但即使这样轮子也只有上下方向上的自由度， 遇到复 杂路面情况并不能处理很好， 且这类连杆设计的轮子底座在遇到路面上的深坑 时会有轮子悬空的情况， 稳定性差。 因此对于一些排轮设置的底座， 若其能具 有多个方向上的转动自由度， 稳定性会更好。 基于以上的一些情况， 本发明对 排轮底座进行了进一步的研究。
问题的解决方案
技术解决方案
[0005] 针对以上现有技术中的不足， 本发明提供了一种多连杆排轮底座可串联的连杆 结构， 根据需要组装成不同长度的排轮底座， 每个关节可全方位无死角转动， 解决了串联后连杆之间互相制约的问题， 每个轮子都能全部附着于地面， 支架 和上部产品也可全方位转动， 能适应复杂的路面情况， 避震缓冲性能好； 同时 主体采用拼接式的结构， 可根据需要组装， 操作方便。 此外本发明中还涉及该 排轮底座在一些运动设备上的应用。
[0006] 为了解决上述技术问题， 本发明通过下述技术方案得以解决。
[0007] 一种多连杆排轮底座， 该排轮底座包括主体和设于主体上的轮子， 所述主体由 多个转动连接在一起的连杆组件组成， 所述轮子设于该连杆组件上； 所述连杆 组件包括中间连杆和端部连杆， 所述中间连杆的两侧设有转动连接位， 所述端 部连杆的一侧设有转动连接位， 相邻连杆组件上的转动连接位通过连接装置实 现可全方转动连接。
[0008] 传统的轮子底座的主体支架一般都为一体式结构， 或者简单的只能上下运动的 机械连杆结构， 缺少可塑性， 缓冲避震能力差， 不能做到串联连杆的全方位转 动。 本发明中的多连杆排轮底座中， 采用组装式串联的连杆组件来组装成主体 ， 可以根据需要选择不同数量的连杆组件， 可以组装成不同长度的主体， 模块 化操作方便。 同时， 最重要的， 本发明中的相连的连杆组件之间通过连接装置 相连接， 可以上下转动也可以横向偏转， 实现了三维空间的全方位独立转动， 因此排轮底座具有很强的翻越障碍物的能力和全地形适应能力， 遇到坑坑洼洼 的路面时， 轮子可以自行根据地形全附着于地面， 稳定性好， 同时连杆组件之 间的转动连接也使整体具有很好的避震能力， 多连杆串联的结构和可全方位转 动的关节结构使轮子拥有全地形附着地面的能力， 并且轮子不会急速下降， 安 全性高且适应性强。
[0009] 作为优选， 所述转动连接位包括作为插入部的插入式连接位和用于接收该插入 式连接位的窗口式连接位， 所述插入式连接位和窗口式连接位上设有对齐的第 一通孔和第二通孔， 连接装置装配于第一通孔和第二通孔中实现相邻连杆组件 的转动连接。 相邻的连杆组件之间通过插入式连接位和窗口式连接位对齐后进 行装配固定， 操作方便。
[0010] 作为优选， 所述连接装置包括设于第二通孔中的组件体和设于该组件体中的连 接轴， 还包括设于第一通孔中的球形转动体， 所述连接轴贯穿该球形转动体。 球形转动体的设置使相连的连杆组件之间产生横向转动的空间， 因此在经过坑 坑洼洼路面的时候可以适应路面进行横向摆动， 减少震动。
[0011] 作为优选， 所述球形转动体中设有转珠， 所述连接轴贯穿该转珠， 该转珠起到 类似球轴的作用， 可以在连接轴的方向上产生各个角度转动， 使连杆组件产生 全方位转动， 且自由度高。
[0012] 作为优选， 所述组件体为弹性体， 提供避震效果。

本发明的实施方式
[0041] 下面结合附图与具体实施方式对本发明作进一步详细描述。
[0042] 参照图 1至图 22， 本发明中的一种多连杆排轮底座， 该排轮底座包括主体 1和设 于主体 1上的轮子 2， 所述主体 1由可全方位活动的关节且连接在一起的多个连杆 组件组成， 所述轮子 2设于该连杆组件两端部的轮子安装结构 13上， 该轮子安装 结构 13及轮子 2为常规结构中的技术； 所述连杆组件包括中间连杆 11和端部连杆 12, 所述中间连杆 11的两侧设有全方位可自由的转动连接位， 所述端部连杆 12 的一侧设有全方位可自由的转动连接位， 相邻连杆组件上的转动连接位通过全 方位可自由的连接装置实现转动连接， 该结构使连杆组件可以根据需要组装， 如图 1-图 4中， 分别为 3个连杆组件的底座和 4个连杆组件的底座。
[0043] 具体的， 所述转动连接位包括作为插入部的插入式连接位和用于接收该插入式 连接位的窗口式连接位 （窗口式连接位上设有供插入式连接位插入的窗口 122）
， 所述插入式连接位和窗口式连接位上设有对齐的第一通孔 111和第二通孔 123 ， 连接装置装配于第一通孔 111和第二通孔 123中实现相邻连杆组件的转动连接 ; 插入式连接位和窗口式连接位分别设于相邻的连杆组件上用于连接， 可以根 据需要设置， 如图 5中， 中间连杆 11的两端都为插入式连接位， 端部连杆 12上都 为窗口式连接位， 可以实现配合装配， 也可以为： 中间连杆 11的两端都为窗口 式连接位， 端部连杆 12上都为插入式连接位， 也可以实现装配； 或者也可以为 中间连杆 11的两端分别窗口式连接位和插入式连接位， 两个端部连杆 12上分别 为窗口式连接位和插入式连接位， 也可以实现装配， 这些都落入本发明的保护 范围中。 所述连接装置包括设于第二通孔 123中的组件体 124和设于该组件体 124 中的连接轴 125 , 所述组件体 124为弹性体， 所述连接装置是将第二通孔 123、 第 一通孔 111用组件体 124和设于该组件体 124中穿过转珠 112的连接轴 125和包裹住 该转珠 112的壳体 113 , 达到关节内全方位旋转的能力； 还包括设于第一通孔 111 中的球形转动体， 所述连接轴 125贯穿该球形转动体； 所述球形转动体包括其中 的转珠 112和包裹住该转珠 112的壳体 113， 所述连接轴 125贯穿该转珠 112， 且壳 体 113上供连接轴 125穿过的孔的孔径大于连接轴 125的直径， 这使得转珠 112及 连接轴 125可以在壳体 113中全方位旋转， 提供给连杆组件上下左右旋转的能力 。 图中所示的壳体 113为独立的结构， 也可以为集成到第一通孔 111中的结构， 均落入本发明的保护范围中。
[0044] 此外， 本发明中的主体 1上还设有起连接作用的多个固定装置， 一种实施方式 中， 所述固定装置包括设于主体 1上固定孔 121、 设于该固定孔 121中的全方位的 球形转动体、 贯穿该全方位的球形转动体的连接轴 125 ; 该全方位的球形转动体 的结构与第一通孔 111的全方位的球形转动体的结构相同， 起到产生上下左右全 方位旋转的作用， 相应的， 固定孔 121上也设有弹性体， 其他的功能结构通过连 接板 4固定在连接轴 125上实现固定。 另一种实施方式中， 所述固定装置包括设 于主体 1上的安装孔 141， 该安装孔 141中设有球轴组件 14， 该球轴组件 14中的连 接轴向上伸出； 所述球轴组件 14包括底座 142、 设于该底座 142中的球轴 143、 套 于该球轴 143上的定位套 144， 所述球轴 143上的连接轴从该定位套 144中伸出。 此外， 所述定位套 144的上表面设有定位孔 146 , 该定位孔 146在主体 1前进方向 上的孔径小于在主体 1两侧方向上的孔径， 使得左右方向上的可偏转程度大， 定 位套 144上覆盖有弹性套 145 , 能够承受挤压形变， 也能产生复位弹力。
[0045] 以上结构中的连接结构中， 具有连接轴 125的另一侧通过螺栓 126固定， 从图 10 中可以看出。 此外， 从图 12中可以看出， 在中间连杆 11的两侧的转动连接位上 设有限位结构 115 , 用于防止转动连接的连杆组件发生过度转动。
[0046] 传统的轮子底座的主体支架一般都为一体式结构， 或者简单的只能上下运动的 机械连杆结构， 缺少可塑性， 缓冲避震能力差。 本发明中的多连杆排轮底座中 ， 采用组装式的连杆组件来组装成主体， 可以根据需要选择不同数量的连杆组 件， 可以组装成不同长度的主体， 模块化操作方便。 同时， 最重要的， 本发明 中的相连的连杆组件之间通过连接装置相连接， 可以上下转动也可以全方位旋 转， 实现了三维空间的全方位独立转动， 因此具有很强的翻越障碍物的能力， 和全地形适应能力， 遇到坑坑洼洼的路面时， 轮子可以自行根据地形进行上升 、 下降、 左倾斜、 右倾斜等变化， 可以自行根据地形全附着于地面， 使轮子不 会急速下降， 安全性高且适应性强， 稳定性好。
[0047] 此外， 本发明还涉及多连杆排轮底座的应用， 具体为以下应用中的一种或多种 : （1） 多连杆排轮底座作为轮滑鞋底座的应用， 如图 13所示， 通过鞋底固定板 5将鞋体 8固定在排轮底座上； （2） 多连杆排轮底座作为滑板底座的应用， 如图 14和图 15所示， 且图 14和图 15中分别为两种不同的固定装置， 图 14中通过连接 板 4将滑板 7固定在排轮底座上， 图 15中采用另一种固定装置将滑板 7固定在排轮 底座上； （3） 多连杆排轮底座作为滑板车底座的应用， 如图 16所示， 通过连接 板 4将滑板车主体 6固定在排轮底座上； （4） 多连杆排轮底座作为摇摆车底座的 应用， 该应用的图在本申请中未示出。
[0048] 以上应用中， 都能使运动设备在使用时具有很好的稳定性和避震效果， 安全性 能好。 此外， 在滑板车的应用中， 还涉及刹车结构的一种改进， 具体如图 17-20 所示， 结构如下： 该刹车结构设于滑板车的尾部， 其工作原理是踩踏件 61绕第 二转轴 65转动， 带动下压球 63随着刹车片 62的上下左右一起转动， 实现刹车功 育 g， 该刹车片 62的端部通过具有弹性的弯折金属片固定在端部连杆 12上， 踩踏 件 61的端部通过第一转轴 64固定在滑板车上。 该结构中， 当人用脚踩在踩踏件 6 1上时， 在下压球 63和刹车片 62的共同作用下， 使刹车片 62与轮子 2接触， 实现 刹车。
[0049] 该结构中， 通过下压球 63与刹车片 62相抵， 保证了无论端部连杆 12如何偏转、 升降， 下压球 63都能与刹车片 62很好的接触， 不会使刹车失效； 图 17至 19为端 部连杆 12不同状态下， 下压球 63与刹车片 62相抵的示意图。
[0050] 本发明的保护范围包括但不限于以上实施方式， 本发明的保护范围以权利要求 书为准， 任何对本技术做出的本领域的技术人员容易想到的替换、 变形、 改进 均落入本发明的保护范围。 工业实用性
