Description
本发明属于底盘机械技术领域,特别是有关于一种悬挂装置、悬挂减振装置及六轮仿生底盘以应用于机器人、可移动式机器人或是车辆中,利用悬挂装置、悬挂减振装置以提高机器人、可移动式机器人或是车辆的越障能力。
现有技术方案中,可移动机器人内部具备一个重要的机构是悬挂减振装置,悬挂减振装置可以减少可移动机器人在移动过程中造成的振动,令可移动机器人稳定工作。现有的悬挂减振装置使用直线轴承式悬挂***,然而这种直线轴承式悬挂***的结构不紧凑,所占空间大,直线轴承本身的成本也比较高,而且当直线轴承式悬挂***安装于悬挂减振装置时,安装面的加工需要很高的加工精度,使得整个悬挂减振装置的寿命降低,成本也很高。
此外,随着科技日新月异,车辆工程的技术也随之进步。一般车辆分为车体和轮式底盘两大架构,常见的轮式底盘至少包括有轮胎、车架、转向器(或称换向器)、动力供给器、煞车器及悬吊器。其中轮胎、转向器及悬吊***是控制车辆的行进方向及避免翻覆的重要组件。一般车辆在行进时,会遇到转弯或是跨越障碍物等问题,因此如何使车辆在行进时保持稳定及能够顺利的转弯是车辆工程中一直不断研究的课题。
关于转弯的课题,轮胎及转向器是控制车辆在转弯时的主要核心,现有技术的转向器是利用单连杆式的转向器,其特点在于:驾驶能单独且直接的控制前轮的轮胎,例如:在四轮的车辆中,具有两个转向器来分别控制车辆的两个前轮,当车辆欲转弯时,驾驶会转动方向盘来控制轮胎朝向欲转弯的方向,受到转向器控制的前轮即会朝着欲转弯的方向转动,车辆的后轮则连带的朝车辆要转弯的方向一并转动且行进,此类型的转向器对于一般的四轮车辆来说已经足够,但是单连杆式的转向器无法应用于需要车轮数较多的特殊车辆,例如公交车或是多轮具有履带的战车。
另外,车辆的悬吊器是用于稳定车辆,保持车体在各种行进状态,例如在一般水平面例如地面行进、爬坡或是越障的稳定性,悬吊器主要是由弹簧及减震筒所组成,因此悬吊器可以视为减震器。在一般大众所使用的车辆中,其悬吊器可以是独立式悬吊器或是非独立式悬吊器,其中独立式悬吊器的特点在于将轮式底盘的左右半部轮胎分开控制,而非独立式悬吊器则是将车辆的所有的轮胎统一控制。悬吊器还可以分为主动式或是非主动式,两者的差异性则是在于:主动式悬吊器可以根据悬吊器的弹力常数与阻尼系数来运算以适应不同的路面环境,非主动式悬吊器的弹力常数及阻尼系数是固定的,不会依据环境的不同而有所改变。
而近年来,则是将机器人应用于车辆的轮式底盘***。由于一般机器人多使用在野外,或是地面崎岖的环境,或是灾难现场,故用于机器人轮式底盘***较用于车辆的轮式底盘***需有更佳适地性及机动性,故将目前用于车辆的轮式底盘***运用在机器人上,技术有很大的改进空间。在现有技术中披露了一种具有活结悬吊的车辆及活结悬吊的使用方法,其所揭露的底盘装置是适用于军用车辆即适用在地形崎岖的环境,具有好的适地性、越障能力及活动性佳的轮胎,但是现有技术所披露的底盘装置并不能驱动机器人爬梯、转向或是具有任意的行走方向,且其所连接到的移动装置并未披露是机器人移动装置或是仅有车体,即未连带考虑到移动装置的改变对于底盘操作的影响。

请参考图3与图4。图3是表示悬挂减振装置安装于可移动机器人的底盘的侧视图,以及图4是表示安装悬挂减振装置后的底盘的立体示意图。在本实施例中,车架11固定于底盘20,其中车架11通过螺钉(未在图中表示)固定于底盘20以承载机器人(未在图中表示)或是车辆(未在图中表示)。此外,悬挂减振装置10还包括轮组15,轮组15设置于转向装置14上且朝向水平面R,并与水平面R接触,轮组15依据转向装置14的控制来改变整个可移动机器人的行进方向。
本实施例中,当安装有悬挂减振装置1a的可移动机器人在凹凸不平的路面R上移动时,轮组15在移动的过程中遇到障碍,例如石头或是凹坑,悬挂减振装置10中的减振装置13会带动轮组15在经过障碍时上下活动,减振装置13除了可以保持轮组15在移动时随时与路面R是正面接触,以维持整个可移动机器人的平衡之外,同时也借由减振装置13带动轮组15在上下活动时减缓轮组15经过障碍时的振动,使得可移动机器人可以平稳地经过障碍的路面R。于本发明的较优选的实施例中,底盘20上至少安装了6组悬挂减振装置1a,轮组15的数量可对应悬挂减振装置1a的数量。另外,悬挂减振装置1a的减振装置13的数量可以是两个,两个减振装置13分别配置于控制臂组12的两侧(如图2所示),当悬挂减振装置10遇到障碍时,透过在控制臂组12的两侧的减振装置13可以提高减振精度进一步地优化减振效果,每个减振装置13也能够选择性的更换弹性组件,借以调松或是调紧弹性组件来调整底盘20的承载能力。
请参考图5至图7。图5是根据本发明所披露的另一实施例,表示悬挂减振装置的立体示意图,图6是表示悬挂减振装置的侧视图,以及图7是表示悬挂减振装置安装于可移动机器人的底盘的立体示意图。于此实施例中的悬挂减振装置1b与前述的悬挂减振装置1a相似,因此相同的组件以相同的标号表示,在此不再赘述。悬挂减振装置1b与悬挂减振装置1a的差异在于:在悬挂减振装置1b中,减振装置13相对于路面R的一端与底盘20铰接,以及减振装置13朝向路面R的另一端与下控制臂122铰接。
此外,在本发明较优选的实施例中,车架链结架16与地面30呈平行且与转向装置14呈垂直设置,而且每个车架链结架16的两端分别铰接于两个相对的悬挂减振装置1b中的车架11。据此,透过车架链结架16将两个相对的悬挂减振装置1b与底盘20链结成一个封闭式框架,以提高悬挂减振装置1b的固定强度,而且当底盘20上方承载的重量增加时,由悬挂减振装置1b与底盘20所构成的封闭式框架可以降低在底盘20的行进过程中,悬挂减振装置 1b朝向+Y或-Y方向的变形量。
接着请同时参考图8至图10。图8是表示本发明所披露的悬挂减振装置的另一实施例的侧视图,图9是表示本发明所披露的悬挂减振装置的另一实施例的立体示意图,以及图10是表示本发明所披露的具有悬挂减振装置的底盘的另一实施例的立体示意图。在图8至图10中,悬挂减振装置1c与前述实施例中的悬挂减振装置1a、1b的区别在于:悬挂减振装置1c包括轮组铰接座123,其一端与车架11铰接以及另一端与转向装置14固连。如图9所示,轮组铰接座123具有凹槽124(如图中箭头所指之处),此凹槽124用以容置减振装置13,其中减振装置13的一端铰接于车架11,其朝向路面R的另一端铰接于凹槽124,据此,车架11、轮组铰接座123与减振装置13构成一个三角形,悬挂减振装置1c可以通过轮组铰接座123控制转向装置14的运动稳定性。
综上所述,悬挂减振装置1a、1b、1c的减振装置13的两端分别与车架及转向装置铰接,当悬挂减振装置13作用时可以带动轮组15上下活动,并能够保持轮组15与路面以正面的角度来接触,以维持在行进中的底盘20的平衡,使得具有悬挂减振装置1a、1b、1c的底盘20可以平稳越过障碍。
接着,本发明还披露了另一种悬挂组件,请参考图11A至图11B。图11A表示本发明所披露的悬挂组件的一实施例的□□图及图11B表示本发明所披露的悬挂组件的一实施例的立体示意图。在图11A及图11B中,悬挂组件2a至少包括有:支臂组30、悬挂弹簧组件32、转向支架34、转向机构(或可称为转向装置)36、轮毂电机38以及轮组40,其中,支臂组30由第一支臂302及第二支臂304所构成。悬挂弹簧组件32,设置在第一支臂302与第一支臂304之间,且悬挂弹簧组件32的两端分别与第一支臂302及第二支臂304的两端铰接。
于本发明较优选的实施例中,第一支臂302与第二支臂304为长方形肋条,因此作为第一支臂302与第二支臂304的长方形肋条可以分别设置在悬挂弹簧组件32的左右两侧,或是分别设置在悬挂弹簧组件32的上方及下方;于另一较优选的实施例中,作为第一支臂302与第二支臂304的长方形肋条的数量可以是一条或是两条,其目的可以与是为了让悬挂弹簧组件32有支撑点,且利用铰接的方式让悬挂弹簧组件32可以在Y方向及Z方向移动。
另外,在本发明另一较优选的实施例中,第一支臂302与第二支臂304的其中之一可以是凹字型结构,而另一个可以是长方形肋条,其中凹字型结构的两侧的两个端点可以分别与悬挂弹簧组件32铰接,因此当第一支臂302为凹字型结构,且以倒置的方式(即倒凹字型)设置在悬挂弹簧组件32的上方时,第二支臂304可以是长方形肋条且设置在第一支臂302的下方并分别设置在悬挂弹簧组件32的两侧边;于另一较优选的实施例,第一支臂302为长方形肋条,第二支臂304为凹字型结构,使得第一支臂302分别设置在悬挂弹簧组件32的两侧边,而第二支臂304则是设置在悬挂弹簧组件32的下方,同时也是设置在第一支臂302的下方。
于另一较优选的实施例中,可以透过调节悬挂弹簧组件32来调整对机器人(未在图中表示)或是车辆(未在图中表示)的承载能力,在悬挂弹簧组件32的一端具有螺栓(未在图中表示),此螺栓是用来调节悬挂弹簧组件32的弹力,根据承载的机器人(未在图中表示)或是车辆(未在图中表示)以及其重量来调紧或是调松,以适应载重量的变化,当载重量愈大时,若超过螺栓的调节范围,则可以更换悬挂弹簧组件32中的弹簧来配合所需要的载重量。因此,于较优选的实施例中,透过调节悬挂弹簧组件32来调整对机器人(未在图中表示)或是车辆(未在图中表示)的承载能力。
转向支架34的一端分别与第一支臂302及第二支臂304的一端铰接,且转向支架34的另一端与转向机构36铰接,且转向机构36朝向所述水平面方向的一端与轮组40枢接。于较优选的实施例中,轮组40还设有轮毂电机38、此轮毂电机38用以根据控制器(未在图中表示)的控制来提供正向或反向扭矩,以驱动轮组40的行进方向。
于另一较优选的实施例中,悬挂组件2a还包括辅助抬轮支架42,且辅助抬轮支架42分别与第一支臂302及第二支臂304的另一端铰接,且所述辅助抬轮支架42的另一端与机器人(未在图中表示)或是车辆(未在图中表示)固连,使得辅助抬轮支架42与支臂□30、转向支架34形成连杆机构,此连杆机构用以控制轮组40遇到垂直障碍时的运动轨迹。
根据上述,悬挂组件2a中的支臂组30、辅助抬轮支架42及转向支架34构成连杆机构,使得当悬挂组件2a的轮组40遇到垂直障碍时,可以透过此连杆机构来控制轮组40遇到垂直障碍时的运动轨迹。
要说明的是,悬挂组件2a具有最大压缩高度及压缩行程,其中压缩高度指的是转向机构36到轮组40的底部之间的高度H(如图11A所示),于较优选的实施例中,悬挂组件2a对轮组40的压缩高度H为300mm。悬挂组件2a的压缩行程指的是悬挂组件2a将轮组40抬离地面的高度,其压缩行程为0-200mm。
接着,本发明还披露另一种悬挂组件,请参考图12A-图12B。图12A表示本发明所披露的悬挂组件的另一实 施例的结构示意图及图12B表示本发明所披露的悬挂组件的另一实施例的侧视图。在此实施例中,与前述图11A-图11B之间的区别在于:悬挂组件2b还进一步包括有悬挂固定座502及辅助抬轮弹簧组件506。
在图12A及图12B中,悬挂组件2b至少包括有:悬挂固定座502、辅助抬轮支架504、辅助抬轮弹簧组件506、支臂组508、悬挂弹簧组件510、转向支架512及转向机构514,轮组518与转向机构514朝向水平面方向的一端枢接,以及轮毂电机516枢接于轮组518,用以驱动所述轮组518。其中,悬挂固定座502的一端502A与机器人(未在图中表示)或是车辆(未在图中表示)固接;辅助抬轮支架504的一端与悬挂固定座502的另一端502B铰接;辅助抬轮弹簧组件506的一端穿设于悬挂固定座502,并与悬挂固定座502铰接;辅助抬轮弹簧组件506的另一端与辅助抬轮支架504的另一端铰接;支臂组508由第一支臂508a及第二支臂508b所构成,第一支臂508a的一端与辅助抬轮支架504的另一端铰接,第一支臂508a的另一端是与转向支架512铰接,第二支臂508b分别设置在辅助抬轮支架504的两侧且其一端与辅助抬轮支架504铰接,及第二支臂508b的另一端与转向支架512铰接,其中支臂组508的第一支臂508a及第二支臂508b的设置方式还有结构与前述相同,不再重复。
支臂组508的目的用以连接辅助抬轮支架504及转向支架512,且由于支臂组508的两端分别与辅助抬轮支架504及转向支架512铰接,使得辅助抬轮支架504及转向支架512可以透过支臂组508随着整个悬挂组件2b的高度调整其高度;悬挂弹簧组件510的两端分别与第一支臂508a及第二支臂508b的两端铰接;以及转向支架512的一端与转向机构514的一端铰接,且转向机构514朝向水平面方向的另一端与轮组518枢接,根据上述,悬挂组件2b中的支臂组508、辅助抬轮支架504及转向支架512构成连杆机构,使得悬挂组件2b可以透过此连杆机构来控制当轮组518遇到垂直障碍物时的运动轨迹。
在此实施例中,可以透过调节悬挂弹簧组件510来调整对机器人(未在图中表示)或是车辆(未在图中表示)的承载能力,在调节悬挂弹簧组件510中的一端具有螺栓(未在图中表示),此螺栓(未在图中表示)是用来调节悬挂弹簧组件510的弹力,根据承载的机器人(未在图中表示)或是车辆(未在图中表示)以及其重量来调紧或是调松,以适应载重量的变化,当载重量愈大时,若超过螺栓(未在图中表示)的调节范围,则可以更换悬挂弹簧组件510中的弹簧来配合所需要的载重量。因此,在本实施例中,可以透过调节悬挂弹簧组件510来调整对机器人(未在图中表示)或是车辆(未在图中表示)的承载能力。
在此要说明的是,在本发明所披露的悬挂组件2a、2b中,轮毂电机38、516是用来驱动轮组40、518的转向。另外,悬挂组件2a、2b还包括有传感器(未在图中表示)是用以侦测轮组40、518的所在位置、速度及轮组40、518与水平面之间的高度;此外,传感器(未在图中表示)亦同时可以监控转向机构36、514、及悬挂组件2a、2b目前的位置。
另外,悬挂组件2a、2b还进一步包括控制器(未在图中表示),其用以接收由传感器(未在图中表示)所传送的轮组40、518的所在位置、速度及轮组40、518与水平面之间的高度来控制轮组40、518的转向及控制悬挂组件2a、2b的悬挂高度。
因此,根据以上所述,在本发明所披露的悬挂组件2a、2b与机器人(未在图中表示)或是车辆(未在图中表示)连接之后,当机器人(未在图中表示)或是车辆(未在图中表示)在行进中遇到垂直障碍物,例如台阶,时,与悬挂组件2a、2b连接的轮组40、518可以透过轮毂电机38、516根据控制器(未在图中显示)的控制来提供正向或反向扭矩,以驱动轮组40、518的行进方向,而轮组40、518只有正转或是反转的两种形式,轮组40、518与台阶的垂直面之间产生摩擦力,且同时也会产生向上的分力,由于悬挂组件2a、2b对轮组40、518的压缩高度为300mm,而压缩行程为0-200mm,此向上的分力在压缩行程的协同下,克服悬挂弹簧组件32、510的张力之后,轮组40、518会被悬挂组件2a、2b拉抬而沿着阶梯的垂直面向上移动,直到超过该阶梯的垂直面之后,悬挂弹簧组件32、510产生X方向(水平方向)的拉力得以让轮组40、518向前移动而完成越障。
于较优选的实施例中,机器人或车辆的总载荷(机器人或车辆的自重加上有效载荷的重量,以有效载荷包括机器人或车辆运送的货物或人员)为100kg为例,采用6个悬挂组件,每个悬挂组件2a、2b对轮组40、518的压缩高度为300mm,悬挂组件2a、2b的压缩行程范围为0-200mm。机器人或车辆的越障能力与悬挂组件2a、2b的最大压缩行程值正相关,轮组40、518可压缩的高度越大,悬挂弹簧组件32(如图11A及图11B所示)、510(如图12A及图12B所示)的伸缩性越强,悬挂组件2a、2b的压缩行程越大,其越障能力越强。然而最大压缩行程过大,会导致机器人或是车辆的行驶稳定性降低。尤其是当机器人或是车辆的有效载荷较大的时候,随着悬挂组件2a、2b的最大压 缩行程的增加,行驶稳定性会急剧降低。此时可采取增加悬挂组件的结构稳定性或增加机器人或是车辆的轮组数量(例如采用8轮、10轮或是12轮)以提高行驶稳定性。经实验测试,发现当总载荷达到100kg的情况下,悬挂组件2a、2b的最大压缩行程若超过200mm会导致行驶稳定性显着降低,当其行驶在石子路等不平坦路面时,车身及有效载荷会剧烈晃动。

因此,根据以上所述,在本发明所披露的六轮仿生底盘3在行进中遇到垂直障碍(未在图中表示)时,前轮悬挂组件70、中轮悬挂组件80及后轮悬挂组件90具有压缩高度及压缩行程,其中压缩高度指的是转向机构(如前轮转向机构714、中轮转向机构810、后轮转向机构910)顶部到轮组(如前轮组718、中轮组814、后轮组914)的底部之间的高度H(如图13C所示),在本发明较优选的实施例中,前轮悬挂组件70、中轮悬挂组件80及后轮悬挂组件90对轮组(如前轮组718、中轮组814、后轮组914)的压缩高度H为300mm;另外,前轮悬挂组件70、中轮悬挂组件80及后轮悬挂组件90的压缩行程指的是前轮悬挂组件70、中轮悬挂组件80及后轮悬挂组件90分别将前轮组718、中轮组814、后轮组914抬离地面的高度,在本发明较优选的实施例中,压缩行程为0-200mm。因此,当六轮仿生底盘3遇到垂直障碍且其垂直障碍的高度无法让六轮仿生底盘3的前轮组718抬起而跨越垂直障碍时,此时须通过中轮组814及后轮组914向前轮组718所产生的推力,压缩前轮悬挂组件70,使得前轮连杆机构的前轮上支臂组708、前轮辅助抬轮支架704及前轮转向支架712可以带动前轮组718被抬起而可以越障,而中轮悬挂组件80中的中轮上支臂组804的两端是与底盘架60及中轮转向支架808铰接、后轮悬挂组件90中的后轮上支臂组904的两端是与底盘架60及后轮转向支架908铰接,使得中轮上支臂组804及后轮上支臂组904除了可以在Y方向上移动之外,也可以在Z方向移动,就像是节肢动物的腿部动作一样,且中轮上支臂组804及后轮上支臂组904可以分开朝向不同的方向移动,使得中轮上支臂组804及后轮上支臂组904可以分别的带动中轮转向支架708及后轮转向支架808来带动中轮组814及后轮组914来进行越障。
接着,本发明还披露另一种六轮仿生底盘,请参考图14A-图14C。图14A表示本发明所披露的六轮仿生底盘的另一实施例的立体示意图、图14B表示本发明所披露的六轮仿生底盘的另一实施例的俯视图及图14C表示根据图14B中的B-B线段的六轮仿生底盘的另一实施例的截面示意图。在此实施例中,与前述图13A-图13D之间的差异在于,六轮仿生底盘3的前轮悬挂组件70还进一步包括有前轮悬挂固定座及前轮辅助抬轮弹簧组件、中轮悬挂组件80还进一步包括中轮悬挂固定座及后轮悬挂组件90还进一步包括后轮悬挂固定座,其结构以及功能于后详细说明。

图14C是根据图14B中B-B线段的截面示意图,由于前轮悬挂组件70、中轮悬挂组件80以及后轮悬挂组件90在底盘架60是左右对称的设置,因此在以下披露六生仿生底盘4的结构时,以单一一个前轮悬挂组件70、中轮悬挂组件80以及后轮悬挂组件90来说明。另外,在图14A-图14C中,图面上的箭头M表示六轮仿生底盘4的运动行进方向。

接着请参考图16。图16表示六轮仿生底盘的中轮悬挂组件的结构示意图。在图16中,中轮悬挂组件30至少包括有中轮悬挂固定座802、中轮上支臂组804、中轮悬挂弹簧组件806、中轮转向支架808、中轮转向机构810、中轮轮毂电机812以及中轮组814,其中,中轮悬挂固定座802的一端802A与底盘架60的中间固接;中轮上支臂组804由第一中轮上支臂804a及一对第二中轮上支臂804b所构成,第一中轮上支臂804a的一端与中轮悬挂固定座802的另一端802B铰接,第一中轮上支臂804a的另一端与是与中轮转向支架808铰接,一对第二中轮上支臂804b的一端与中轮悬挂固定座802的另一端802B铰接,及第二中轮上支臂804b的另一端与中轮转向支架808铰接,其中,第一中轮上支臂804a是配置在第二前轮上支臂804b的上方。
另外,在较优选的实施例中,与前轮上支臂组708相同,第一中轮上支臂804a为倒凹字型结构,其倒凹字型结构的两侧向外延伸的两端分别与中轮悬挂固定座802及中轮转向支架808铰接;而第二中轮上支臂804b为一对长方形肋条,分别设置在中轮悬挂固定座802及中轮转向支架808的两侧且设置在倒凹字型结构的第一中轮上支臂804a的下方,其中,中轮上支臂组804的目的用以连接中轮悬挂固定座802及中轮转向支架808;以及中轮转向支架808的一端与中轮转向机构810固连,且中轮转向机构810朝向地面方向的一端与中轮组814枢接,且中轮组814与中轮轮毂电机812枢接,根据上述,中轮悬挂组件80中的中轮上支臂组804与中轮转向支架808构成中轮连杆机构,使得在六轮仿生底盘3、4可以利用此中轮连杆机构来控制中轮组814在遇到垂直障碍时的运动轨迹。
请继续参考图17。图17是表示六轮仿生底盘的后轮悬挂组件的结构示意图。在图17中,后轮悬挂组件90至少包括有:后轮悬挂固定座902、后轮上支臂组904、后轮悬挂弹簧组件906、后轮转向支架908、后轮转向机构910、后轮轮毂电机912以及后轮组914,其中,后轮悬挂固定座902的一端902A与底盘架60的后端固接;后轮上支臂组904由第一后轮上支臂904a及一对第二后轮上支臂904b所构成,第一后轮上支臂904a的一端与后轮悬挂固定座902的另一端902B铰接,第一后轮上支臂904a的另一端与是与后轮转向支架908铰接,一对第二后轮上支臂904b的一端与后轮悬挂固定座902的另一端902B铰接,及第二后轮上支臂904b的另一端与后轮转向支架908铰接,其中第一后轮上支臂904a是配置在第二后轮上支臂904b的上方。
另外,在较优选的实施例中,第一后轮上支臂904a为倒凹字型结构,其倒凹字型结构的两侧向外延伸的两端分别与后轮悬挂固定座902及后轮转向支架908铰接;而第二后轮上支臂904b为一对长方形肋条,分别设置在后轮悬挂固定座902及后轮转向支架908的两侧且设置在倒凹字型结构的第一后轮上支臂904a的下方,其中,后轮上支臂组904的目的用以连接后轮悬挂固定座902及后轮转向支架908;以及后轮转向支架908的一端与后轮转向机构910固连,且后轮转向机构910朝向地面方向的一端与后轮组914枢接,且后轮组914与后轮轮毂电机912枢接,根据上述,后轮悬挂组件90中的后轮上支臂组904与后轮转向支架908构成后轮连杆机构,使得在六轮仿生底盘3、4可以利用此后轮连杆机构来控制后轮组914在遇到垂直障碍时的运动轨迹。
此外,在本发明的较优选的实施例中,与前轮上支臂组708相同,第一中轮上支臂804a为倒凹字型结构,其倒凹字型结构的两侧向外延伸的两端分别与底盘架60铰接;而第二中轮上支臂804b为一对长方形肋条,其一端与底盘架60的中间铰接,另一端与中轮转向支架808铰接,且设置在倒凹字型结构的第一中轮上支臂804a的下方,其中,中轮上支臂组304的目的用以连接底盘架60及中轮转向支架808;以及中轮转向支架808的一端与中轮转向机构810固连,且中轮转向机构810朝向地面方向的一端与中轮组814枢接,且中轮组814与中轮轮毂电机812枢接,根据上述,中轮悬挂组件80中的中轮上支臂组804与中轮转向支架808构成中轮连杆机构,使得在六轮仿生底盘3、4可以利用此中轮连杆机构来控制中轮组814在遇到垂直障碍时的运动轨迹。
在此要说明的是,在本发明所披露的六轮仿生底盘3、4中,前轮悬挂组件70的前轮轮毂电机716、中轮悬挂组件80的中轮轮毂电机812及后轮悬挂组件90的后轮轮毂电机912是分别用来驱动前轮组718、中轮组814及后轮组914旋转。另外,六轮仿生底盘3、4还包括有传感器(未在图中表示)是用以侦测前轮组718、中轮组814及后轮组914的所在位置、速度及前轮组718、中轮组814及后轮组814与水平面之间的高度;此外,传感器亦同时可以监控前轮转向机构714、中轮转向机构810及后轮转向机构910及前轮悬挂组件70、中轮悬挂组件80及/或后轮悬挂组件90的位置。另外,六轮仿生底盘3、4还进一步包括控制器(未在图中表示),其用以接收由传感器所传送 的前轮组718、中轮组814及/或后轮组914的所在位置、速度及前轮组718、中轮组814及后轮组914与水平面之间的高度来分别控制前轮组718、中轮组814及后轮组914的转向及控制前轮悬挂组件70、中轮悬挂组件80及/或后轮悬挂组件90的悬挂高度。
因此,根据以上所述,在本发明所披露的六轮仿生底盘3、4在行进中遇到垂直障碍(未在图中表示)时,前轮悬挂组件70、中轮悬挂组件80及后轮悬挂组件90可以让前轮组714、中轮组814及后轮组914分别产生上下200mm高度的运动行程,因此在遇到垂直障碍且其垂直障碍的高度无法让六轮仿生底盘3、4的前轮组718抬起而跨越垂直障碍时,此时须通过中轮组814及后轮组914向前轮组718所产生的推力,压缩前轮悬挂组件70中的前轮辅助抬轮弹簧组件706,使得前轮组718被抬起而可以越障,而六轮仿生底盘3、4的越障过程于后详述。另外,在六轮仿生底盘3、4进行越障的过程中,六轮仿生底盘3、4的前轮悬挂组件70中的前轮悬挂弹簧组件710、中轮悬挂组件80的中轮悬挂弹簧组件806及后轮悬挂组件90的后轮悬挂弹簧组件906亦可以使中轮组814及后轮组914产生越障高度为300mm的运动行程,如图18A所示,在图18A中是将六轮仿生底盘3、4的前轮悬挂弹簧组件710、中轮悬挂弹簧组件806及后轮悬挂弹簧组件906向下(朝向地面方向)压缩行程范围为0-200mm;而在图18B中,则是将六轮仿生底盘3、4的前轮悬挂弹簧组件710、中轮悬挂弹簧组件806及后轮悬挂弹簧组件906向上升高300mm高度,因此,六轮仿生底盘3、4可以具有至少±200mm高度的减振行程。
因此,综上所述,当轮组(前轮组718、中轮组814、后轮组914)可压缩的高度越大,悬挂弹簧组件(前轮悬挂弹簧组件710、中轮悬挂弹簧组件806、后轮悬挂弹簧组件906)的伸缩性越强,悬挂组件(前轮悬挂组件70、中轮悬挂组件80、后轮悬挂组件90)的压缩行程越大,使得六轮仿生底盘3、4的越障能力越强。
要说明的是,于先前所记载的悬挂减振装置(如图1-图10)或是悬挂组件(如图11A-11B及图12A-12B),亦可以设置于六轮仿生底盘3、4,使得具有上述的悬挂减振装置(如图1-图10)或是悬挂组件(如图11A-11B及图12A-12B)可以分别作为前轮、中轮及后轮的悬挂减振装置或是悬挂组件,让具有悬挂减振装置(如图1-图10)或是悬挂组件(如图11A-11B及图12A-12B)的六轮仿生底盘(未在图中表示)与前述实施例中的六轮仿生底盘3、4一样来进行转弯或是爬坡越障等功能,因此不再针对悬挂减振装置(如图1-图10)或是悬挂组件(如图11A-11B及图12A-12B)与底盘结合之后的内容作进一步的陈述。
接着请参考图19。图19是根据本发明所披露的六轮仿生底盘在越障时的一实施例的示意图。在说明图19的同时,也请一并参考图15A、图16及图17。在图19中,六轮仿生底盘3、4在平面行驶时保持在第一峰值转矩为10牛顿·米(N·m)恒定输出,当传感器感知道前轮组718与垂直障碍Q接触时,此时传感器会发出障碍物的信号通知控制器,控制器在接收到此信号之后,会对前轮轮毂电机716、中轮轮毂电机812及后轮轮毂电机912发出控制信号以第二峰值转矩为13N·m来运行,此时前轮组718受到垂直障碍Q产生反作用力N
3及前轮组718与平面30之间的磨擦力F
3,其合力会使前轮悬挂弹簧组件710压缩,具体来说是前轮组718所受到垂直障碍Q后所产生的反作用力N
3与前轮组718与平面30之间的磨擦力F
3的合力来压缩前轮悬挂组件70中的前轮悬挂弹簧组件710及前轮辅助抬P轮弹簧组件706,而前轮悬挂组件70带动前轮组718朝向P的方向运动,使得前轮组718被抬升,而可以翻越垂直障碍Q而实现越障的目的。
当前轮组718完成越障之后,六轮仿生底盘3、4继续向前行驶(图面中箭头M的方向)时其控制器会发出信号控制前轮轮毂电机716以第一峰值转矩为10N·m来运行。当六轮仿生底盘3、4继续向前行驶时,且当传感器感知到中轮组814与垂直障碍Q接触时,其传感器会再对控制器发出遇到障碍物的信号,控制器在接收到信号之后对中轮轮毂电机812发出控制信号以第二峰值转矩13N·m运行,此时中轮组814受到垂直障碍Q产生反作用力N
2与中轮组814与平面30之间的磨擦力F
2,其合力会使中轮悬挂弹簧组件806被压缩,具体来说是中轮组814受到垂直障碍Q后所产生的反作用力N
2与中轮组314与路面R之间的磨擦力F
2的合力来压缩中轮悬挂组件80中的中轮悬挂弹簧组件806,而中轮悬挂组件80会带动中轮组814同样是朝着P的方向运动,使得中轮组814借助牵引力和自身的动力,以被动的方式被抬升而可以翻越垂直障碍Q,而让中轮组814实现越障的目的。
当六轮仿生底盘3、4完成了前轮组718及中轮组814翻越垂直障碍Q之后,六轮仿生底盘3、4的前轮轮毂电机716、中轮轮毂电机812及后轮轮毂电机912会以第一峰值转矩为10N·m驱动前轮组718、中轮组814及后轮组914继续向前行驶(朝着图面箭头M的方向),当后轮组914与垂直障碍物Q接触时,传感器会再对控制器发出遇到障碍物的信号,控制器在接收到此信号之后,对后轮轮毂电机412发出控制信号以第二峰值转矩13N·m运行,此时 后轮组914受到垂直障碍物Q产生反作用力N
1与后轮组914与平面30之间的磨擦力F
1,其合力会使后轮悬挂弹簧组件906被压缩,具体来说是后轮组914受到垂直障碍Q后所产生的反作用力N
1与后轮组914与平面30之间的磨擦力F
1的合力来压缩后轮悬挂组件90中的后轮悬挂弹簧组件906,而后轮悬挂组件90会带动后轮组914同样是朝着P的方向运动,使得后轮组914同样借助牵引力和自身的动力,以被动的方式被抬升而可以翻越垂直障碍Q,而让后轮组914实现越障的目的。当六轮仿生底盘3、4的前轮组718、中轮组814及后轮组914完成了翻越垂直障碍Q之后,其控制器会发出信号来控制六轮仿生底盘3、4的前轮轮毂电机716、中轮轮毂电机812及后轮轮毂电机912由第二峰值转矩为13N·m变更为以第一峰值转矩为10N·m来驱动前轮组718、中轮组814及后轮组914继续向前行驶(朝着图面箭头M的方向)。要说明的是,本发明所披露的六轮仿生底盘3、4在调整前轮悬挂组件70、中轮悬挂组件80及后轮悬挂组件90的硬度时,前轮悬挂组件70、中轮悬挂组件80及后轮悬挂组件90对前轮组718、中轮组814及后轮组914的压缩行程为0-200mm,因此六轮仿生底盘3、4可以实现压缩高度为300mm的垂直越障能力,具体计算如下所述。
影响六轮仿生底盘3、4越障高度的因素其可能包括有:六轮仿生底盘3、4的重心位置、轮毂电机(前轮轮毂电机716、中轮轮毂电机812及后轮轮毂电机912)、轮组(前轮组718、中轮组814及后轮组914)与地面之间的摩擦系数,其中六轮仿生底盘3、4的重心位置与底盘架60的结构参数有关,其结构参数可以包括轮组(前轮组718、中轮组814及后轮组914)直径、减震结构弹力及悬挂行程,因此如图20所示,在轮毂电机(前轮轮毂电机716、中轮轮毂电机812及后轮轮毂电机912)的功率足够的条件下,轮组(前轮组718、中轮组814及后轮组914)与地面滚动的情况下,六轮仿生底盘1a、1b的越障高度h的计算方式如下:
Z
2-m
2=h
2 式(4);
因此,根据上述式(1)-式(4)可以计算得到越障高度h为:
其中,L
1为各上支臂组的长度、L
2为各转向支架的长度、L
