具体实施方式
为使本申请的上述目的、特征和优点能够更加明显易懂,下面结合附图对本申请的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本申请。但是本申请能够以很多不同于在此描述的其它方式来实施,本领域技术人员可以在不违背本申请内涵的情况下做类似改进,因此本申请不受下面公开的具体实施例的限制。
参见图1,本申请第一方面提供了一种载具A1000,该载具A1000可以包括载具本体A200以及根据本发明一实施例提供的定位组件A100(见图2),其中,定位组件A100用于将载具本体A200安装至汽车座椅(图中未示出)上,以提高儿童或婴幼儿乘坐汽车时的安全性。需要说明的是,载具本体A200例如可以是座椅、提篮或睡箱等。下文在对载具A1000进行描述的同时,将一并对定位组件A100进行说明。
参见图2至图4,在一实施例中,定位组件A100包括第一定位组件A110和第二定位组件A120,第一定位组件A110可转动地设置于第二定位组件A120上。其中,第一定位组件A110和第二定位组件A120两者中的一者设有第一轨道A131和第二轨道A132,另一者设有第一滑动件A141和第二滑动件A142。例如,如图3和图4所示,第一定位组件A110上设有第一滑动件A141和第二滑动件A142,第二定位组件A120上设有第一轨道A131和第二轨道A132,其中,第一滑动件A141与第二滑动件A142沿第一定位组件的前后方向(即Q1、Q2方向)间隔设置,第一轨道A131沿第一方向F1延伸,第二轨道A132沿第二方向F2延伸,第一方向F1与第二方向F2相交错。在一实施例中,第一滑动件A141沿第一轨道A131或第二轨道A132中的一者滑移,第二滑动件A142沿第一轨道A131或第二轨道A132中的另一者滑移。这样,可使第一定位组件A110相对于第二定位组件A120的转动而同时进行位移(见图8和图10)。
在一实施例中,如图1至图4所示,第一定位组件A110用于连接载具本体A200,第二定位组件A120用于连接汽车座椅。具体地,第一定位组件A110上设有第一连接机构A150(例如卡合钩),第一连接机构A150主要用于与载具本体A200底部的卡合件(图中未示出)连接。第二定位组件A120上设有座椅连接机构A160(例如ISOFIX连接器)以及支撑腿A170,座椅连接机构A160主要用于将第二定位组件A120固定至汽车座椅上,支撑腿A170主要用于抵靠车辆内部的地板。这样,当定位组件A100安装至汽车座椅上,且载具本体A200安装至定位组件A100后,可通过转动第一定位组件A110的方式改变载具本体A200的朝向,使得载具本体A200具有不同的使用模式。在一些实施例中,载具本体A200的朝向取决于第一轨道A131以及第二轨道A132的延伸方向。例如,当第一轨道A131沿第一方向F1延伸,第二轨道A132沿第二方向F2延伸时,载具本体A200随第一定位组件A110相对于第二定位组件A120转动后具有朝向于第一方向F1或第二方向F2的使用模式。
需要说明的是,在本实施例中,第一定位组件A110具有前端和后端,为了清楚理解第一定位组件A110的各端部,以载具本体A200安装至第一定位组件A110上为例,载具本体A200的前后方向与第一定位组件A110的前后方向相平行。具体地,当婴幼儿或儿童乘坐于载具本体A200内时,第一定位组件A110的前端相对于后端更靠近婴幼儿或儿童的脚部,反之,第一定位组件A110的后端相对于前端更靠近婴幼儿或儿童的头部。当第一定位组件A110朝向于某一方向时,即意味着载具本体A200也朝向该同一方向;同时,乘坐于载具本体A200内的儿童亦朝向该同一方向。为了直观了解载具本体A200以及第一定位组件A110的前后方向,各附图中分别用箭头Q1和Q2示意性示出前方向和后方向,Q1方向与Q2方向平行且相反。
还需要说明的是,在本实施例中,当定位组件A100(第二定位组件A120)安装于汽车座椅上时,第一方向F1是指汽车的前后方向,第二方向F2是指汽车的左右方向。具体地,第一方向F1与第二方向F2相垂直。更具体地,在本实施例中,第一方向F1包含了两个方向(即前方向和后方向),这两个方向平行且相反。同样地,第二方向F2也包含了两个方向(即左侧方向和右侧方向),这两个方向平行且相反。为了便于区分汽车的前方向、后方向、左侧方向和右侧方向,在各附图中分别用箭头F和B示意性示出前方向和后方向,分别用箭头L和R示意性示出左侧方向和右侧方向。因此,后文所提第一定位组件A110相对于第二定位组件A120沿第一方向F1朝向于汽车车头是指第一定位组件A110的前端朝向于F方向;第一定位组件A110相对于第二定位组件A120沿第一方向F1朝向于汽车车尾是指第一定位组件A110的前端朝向于B方向;第一定位组件A110相对于第二定位组件A120沿第二方向F2朝向于汽车的右侧是指第一定位组件A110的前端朝向于R方向;第一定位组件A110相对于第二定位组件A120沿第二方向F2朝向于汽车的左侧是指第一定位组件A110的前端朝向于L方向。
需要说明的是,本申请的涉及的这些方位术语仅表示相对位置关系,用于使本申请实施例的描述更加清楚,并不用于对本申请的保护范围产生不当限定。
参见图4,在本实施例中,定义第一轨道A131与第二轨道A132的交叉点为交叉中心A133。第一轨道A131和第二轨道A132均被交叉中心A133分割形成两个轨段。例如第一轨道A131被交叉中心A133分割形成第一轨段A1311和第二轨段A1312,第二轨道A132被交叉中心A133分割形成第三轨段A1321和第四轨段A1322。其中,第一轨段A1311由交叉中心A133沿第一方向F1向汽车的车头方向延伸,即第一轨段A1311由交叉中心A133沿F方向延伸,第二轨段A1312由交叉中心A133沿第一方向F1向汽车的车尾方向延伸,即第二轨段A1312由交叉中心A133沿B方向延伸;第三轨段A1321由交叉中心A133沿第二方向F2向汽车的左侧方向延伸,即第三轨段A1321由交叉中心A133沿L方向延伸,第四轨段A1322由交叉中心A133沿第二方向F2向汽车的右侧方向延伸,即第四轨段A1322由交叉中心A133沿R方向延伸。
在一实施例中,如图3所示,第一定位组件A110大致呈圆盘状结构,第一滑动件A141设置在第一定位组件A110的圆心处,第二滑动件A142偏离圆心设置。需要说明的是,第一定位组件A110大致呈圆盘状结构时,第一定位组件A110的圆心即为其几何中心。当然,在其他实施例中,第一定位组件A110可以是其他对称形状(例如椭圆形、矩形等),第一滑动件A141可以设置在第一定位组件A110的几何中心或偏离几何中心的位置;又或者,第一定位组件A110还可以是不对称的形状。
需要说明的是,在本实施例中,如图2所示,第二定位组件A120沿第一方向F1以及第二方向F2的长度均大于第一定位组件A110的直径。当第一定位组件A110相对于第二定位组件A120转动至朝向于第一方向F1(例如汽车车头或车尾)时,第一定位组件A110的圆心(即第一定位组件A110的几何中心)与第二定位组件A120的几何中心同轴设置,第一定位组件A110在第二定位组件A120上的正投影位于第二定位组件A120的范围内。换句话说,当第一定位组件A110朝向于第一方向F1时,第一定位组件A110的下表面(即朝向第二定位组件A120的面)均能受到第二定位组件A120上表面的支撑,其相对于第二定位组件A120而言不存在悬空部分。
参见图2至图4,在本实施例中,第一滑动件A141沿第二轨道A132滑移,第二滑动件A142沿第一轨道A131滑移。当第一定位组件A110相对于第二定位组件A120沿第一方向F1朝向于汽车车头(即F方向)时(见图2),第一滑动件A141位于交叉中心A133,第二滑动件A142位于第二轨段A1312内。当第一定位组件A110相对于第二定位组件A120沿第一方向F1朝向于汽车车尾(即B方向)时,第一滑动件A141位于交叉中心A133,第二滑动件A142位于第一轨段A1311内。当第一定位组件A110相对于第二定位组件A120转动至朝向于第二方向F2时(见图8和图10),第一定位组件A110整体相对于第二定位组件A120沿第二方向F2位移。具体地,第一定位组件A110相对于第二定位组件A120沿第二方向F2向外拉出。需要说明的是,“第一定位组件A110相对于第二定位组件A120沿第二方向F2向外拉出”是指第一定位组件A110沿着第二方向F2相对于第二定位组件A120的一侧位移以更靠近这一侧的车门,而非脱离第二定位组件A120。具体而言,是指第一定位组件A110会向第二定位组件所安装汽车座椅对应的一侧移动,更靠近该侧车门。例如,若第二定位组件A120安装在左侧座椅,第一定位组件A110转动至朝向于左侧方向时,第一定位组件A110会更靠近左侧车门。若第二定位组件A120安装在右侧座椅,第一定位组件A110转动至朝向于右侧方向时,第一定位组件A110会更靠近右侧车门。若第二定位组件A120安装在中间座椅,第一定位组件A110转动至朝向于两侧车门中的任一侧时,第一定位组件A110都会更靠近对应侧的车门。以上情况均视为第一定位组件A110沿着第二方向F2相对于第二定位组件A120的一侧向外位移。此时,第一定位组件A110的几何中心相对于第二定位组件A120的几何中心沿第二方向F2的一侧位移。此外,还需要说明的是,“第一定位组件A110相对于第二定位组件A120沿第二方向F2向外拉出”并不限定为必须通过“拉”这一动作来使第一定位组件A110相对于第二定位组件A120沿第二方向F2位移,只要能达成第一定位组件A110相对于第二定位组件A120产生此方向位移的动作,均符合该表达含义。具体地,当第一定位组件A110相对于第二定位组件A120沿第二方向F2朝向于汽车的右侧方向(即R方向)时,第一定位组件A110相对第二定位组件A120向右拉出(见图8),以更靠近右侧车门;此时,第二滑动件A142位于交叉中心A133,第一滑动件A141位于第四轨段A1322内。当第一定位组件A110相对于第二定位组件A120沿第二方向F2朝向于汽车的左侧方向(即L方向)时,第一定位组件A110相对第二定位组件A120向左拉出(见图10),以更靠近左侧车门;此时,第二滑动件A142位于交叉中心A133,第一滑动件A141位于第三轨段A1321内。这样,方便用户从载具本体A200内抱出儿童或将儿童抱进载具本体A200内(见图1)。
参见图2,在一实施例中,定位组件A100还包括防护机构A180。该防护机构A180设置在第二定位组件A120上并可相对于第二定位组件A120滑动,且第一定位组件A110可相对于防护机构A180转动。具体地,防护机构A180套设在第一定位组件A110外,但第一定位组件A110可相对防护机构A180转动。此外,当第一定位组件A110相对于第二定位组件A120在朝向于第一方向F1和第二方向F2之间切换时,第一定位组件A110与防护机构A180驱动配合,以使防护机构A180能够在第二定位组件A120上沿第二方向F2左右移动。
参见图2至图5,在一实施例中,第二定位组件A120上沿第一方向F1间隔形成有两个凸体A121,两个凸体A121之间形成了安装空间A122。具体地,第一轨道A131和第二轨道A132均位于安装空间A122内,第一定位组件A110可转动地设置在安装空间A122内,即可视为第一定位组件A110可转动地设置于第二定位组件A120上并位于两个凸体A121之间。每一凸体A121朝向于第一定位组件A110的一侧分别形成有一槽型结构A1212。具体地,两个凸体A121均设置在第二定位组件A120的上表面,两个凸体A121上均形成有限位凸部A1211,两个限位凸部A1211均朝向于安装空间A122突出。这样,每一限位凸部A1211与第二定位组件A120的上表面之间形成了一具有开口的槽型结构A1212。
在一实施例中,结合图2、图6至图11,防护机构A180包括防护壳A181,防护壳A181呈环状结构并围设在第一定位组件A110的外周,防护壳A181的外边缘能够插入上述两个槽型结构A1212内并能够在两个槽型结构A1212内滑动。当第一定位组件A110相对于第二定位组件A120沿第二方向F2向外拉出时,即可视为第一定位组件A110相对于第二定位组件A120转动至朝向于第二方向F2时,防护壳A181的部分边缘仍插设在两个槽型结构A1212内(见图8、图10和图11)。这样,防护壳A181能够有效遮挡住第一定位组件A110与凸体A121之间的间隙,确保用户在操作过程中无法将手部伸入该间隙,从而有效预防夹手的风险。此外,当第一定位组件A110转动至朝向于第二方向F2时,防护壳A181仍能够卡设在槽型结构A1212内,这样,增加了第一定位组件110的支撑点数量,使第一定位组件A110在转动至侧向(例如左侧或右侧)时,不仅能受到来自第一滑动件A141和第二滑动件A142的支撑,还能通过防护壳A181卡设于槽型结构A1212内的方式受到额外的支撑,从而提高了第一定位组件A110转动至侧向时的稳定性。
下面结合图2至图5以及图8至图10,简单说明防护机构A180的工作原理。
当第一定位组件A110相对于第二定位组件A120由朝向于汽车车头方向向汽车的右侧方向转动时(即由图2向图8切换),如图3和图4所示,第一滑动件A141由交叉中心A133向第四轨段A1322远离交叉中心A133的一端移动,且第二滑动件A142由第二轨段A1312远离交叉中心A133的一端向交叉中心A133移动,第一定位组件A110会相对第二定位组件A120向右转动的同时向右滑移,使得第一定位组件A110更靠近右侧车门,第一定位组件A110的前端边缘逐渐相对于第二定位组件A120的右侧边缘向外突出(见图8)。当然,在其他实施例中,若第二定位组件A120的尺寸足够大,即便第一定位组件A110相对第二定位组件A120转动至朝向于汽车的右侧方向(即R方向),使第一定位组件A110更靠近右侧车门,但第一定位组件A110的前端边缘不会相对于第二定位组件A120的右侧边缘向外突出。具体地情况依据实际设计而定,在此不作具体限制。由于防护壳A181套设在第一定位组件A110的外周,且第一定位组件A110可相对防护壳A181转动,因此,第一定位组件A110在进行转动和滑移的同时会推动防护壳A181沿第二方向F2向汽车的右侧方向移动,使得防护壳A181沿第二方向F2延伸的外边缘A181a能够相对凸体A121在槽型结构A1212内沿第二方向F2向右侧滑动。
当第一定位组件A110相对于第二定位组件A120由朝向于汽车的右侧方向向汽车车尾的方向转动时(即由图8向图9切换),第二滑动件A142由交叉中心A133向第一轨段A1311远离交叉中心A133的一端移动,且第一滑动件A141由第四轨段A1322远离交叉中心A133的一端向交叉中心A133移动,第一定位组件A110会相对第二定位组件A120向后转动的同时向交叉中心A133滑移,使得第一定位组件A110逐渐复位至第二定位组件A120上(见图9)。在此过程中,第一定位组件A110相对防护壳A181转动并推动防护壳A181沿第二方向F2向汽车的左侧方向移动,使得防护壳A181沿第二方向F2延伸的外边缘能够相对凸体A121在槽型结构A1212内沿第二方向F2向左侧滑动。
当第一定位组件A110相对于第二定位组件A120由朝向于汽车车尾的方向向汽车的左侧方向转动时(即由图9向图10切换),第一滑动件A141由交叉中心A133向第三轨段A1321远离交叉中心A133的一端移动,第二滑动件A142由第一轨段A1311远离交叉中心A133的一端向交叉中心A133移动,第一定位组件A110会相对于第二定位组件A120转动至朝向于左侧并向第二定位组件A120的左侧滑移,使得第一定位组件A110更靠近左侧车门,第一定位组件A110的前端边缘逐渐相对于第二定位组件A120的左侧边缘向外突出(见图10和图11)。当然,在其他实施例中,若第二定位组件A120的尺寸足够大,即便第一定位组件A110相对第二定位组件A120转动至朝向于汽车的左侧方向(即L方向),使第一定位组件A110更靠近左侧车门,但第一定位组件A110的前端边缘不会相对于第二定位组件A120的左侧边缘向外突出。具体地情况依据实际设计而定,在此不作具体限制。此过程中,第一定位组件A110相对防护壳A181转动并推动防护壳A181沿第二方向F2继续向汽车的左侧方向移动,使得防护壳A181沿第二方向F2延伸的外边缘能够相对凸体A121在槽型结构A1212内沿第二方向F2向左侧继续滑动。
当第一定位组件A110相对于第二定位组件A120由朝向于汽车的左侧方向向汽车车头的方向转动时(即由图10向图2切换),第二滑动件A142由交叉中心A133向第二轨段A1312远离交叉中心A133的一端移动,且第一滑动件A141由第三轨段A1321远离交叉中心A133的一端向交叉中心A133移动,第一定位组件A110会相对第二定位组件A120转动的同时向交叉中心A133滑移,使得第一定位组件A110逐渐复位至第二定位组件A120上(见图2)。在此过程中,第一定位组件A110相对防护壳A181转动并推动防护壳A181沿第二方向F2向汽车的右侧方向移动,使得防护壳A181沿第二方向F2延伸的外边缘能够相对凸体A121在槽型结构A1212内沿第二方向F2向右侧滑动。
参见图7、图12以及图13,在一实施例中,防护壳A181具有卡持凹部A1811,第一定位组件A110的外边缘插设于卡持凹部A1811内,这样,当第一定位组件A110相对于防护壳A181进行转动的时候,卡持凹部A1811能够限制第一定位组件A110脱离防护壳A181,提高了防护机构A180设置在第一定位组件A110上的稳定性。此外,当载具本体A200安装于第一定位组件A110上时,载具本体A200的重心一般是偏向载具本体A200的后侧,即载具本体A200靠近其背靠部的一侧,于是载具本体A200的前侧具有向上翘起的趋势。由于载具本体A200连接于第一定位组件A110上,第一定位组件A110的外边缘限位于卡持凹部A1811内,防护壳A181的外边缘插设于上述两个槽型结构A1212中,如此,提高了第一定位组件A110在第二定位组件A120上进行旋转及移动的可靠性。
参见图6、图7以及图12,在一实施例中,防护壳A181包括盖体A1812以及第一限位片A1813。其中,盖体A1812围设在第一定位组件A110的外周,盖体A1812沿第二方向F2延伸的外边缘滑动设于两个槽型结构A1212内。第一限位片A1813设于盖体A1812的一侧(即背离第二定位组件A120的一侧)并与盖体A1812的内环壁A18121呈夹角设置,第一限位片A1813与盖体A1812的内环壁A18121形成卡持凹部A1811,该卡持凹部A1811的底壁即为盖体A1812的内环壁A18121。当第一定位组件A110推动防护壳A181沿第二方向F2移动时,可视为第一定位组件A110抵推盖体A1812的内环壁A18121,以使防护壳A181沿第二方向F2向左或向右移动。
在一实施例中,盖体A1812的内环壁A18121的形状与第一定位组件A110的外轮廓形状相匹配,例如当第一定位组件A110呈圆盘状结构时,内环壁A18121的形状可以呈圆形结构,该内环壁A18121的直径大于或等于第一定位组件A110的直径。具体地,如图2、图6和图7所示,盖体A1812的外轮廓与第二定位组件A120的形状相匹配,当第一定位组件A110相对于第二定位组件A120朝向于汽车车头方向时,盖体A1812在第二定位组件A120上的投影位于第二定位组件A120内。例如盖体A1812大致呈方形结构,盖体A1812上设有一中心孔,该中心孔呈圆形结构,且该中心孔的孔壁即为上述盖体A1812的内环壁A18121。更具体地,该中心孔的圆心与盖体A1812的中心点同轴设置,盖体A1812沿第一方向F1的边长W1大于两个凸体A121之间的距离L1(见图5和图6),同时盖体A1812沿第一方向F1的边长W1小于或等于两个槽型结构A1212底壁之间的距离L3。盖体A1812沿第二方向F2的边长W2小于或等于第二定位组件A120沿第二方向F2的长度L2(见图2),这样,当第一定位组件A110带动盖体A1812沿第二方向F2移动后,能够确保盖体A1812的部分边缘仍能够插设在凸体A121的槽型结构A1212内。具体地,在本实施例中,如图6和图7所示,盖体A1812上中心孔的直径略小于盖体A1812的边长,这样,盖体A1812的内环壁A18121与外环壁A18122沿第一方向F1上相切并形成有两个第一相切部A1812a;盖体A1812的内环壁A18121与外环壁A18122沿第二方向F2上相切并形成有两个第二相切部A1812b,盖体A1812的四角形成了四个遮挡部A1812c。当第一定位组件A110转动至朝向于第一方向F1时,两个第一相切部A1812a分别卡设在两个槽型结构A1212中;当第一定位组件A110转动至朝向于第二方向F2时,遮挡部A1812c卡持在槽型结构A1212内并能够遮挡第一定位组件A110与凸体A121之间的间隙。
需要说明的是,当盖体A1812呈正方形结构时,W1等于W2;当然,在其他实施例中,当盖体A1812为长方形结构时,W1可以大于或小于W2。
请参见图6和图7,在一实施例中,第一限位片A1813设有两个,每一第一限位片A1813均呈弧形结构,两个第一限位片A1813绕盖体A1812的内环壁A18121的周向相对设置。当然,在其他实施例中,第一限位片A1813可以设有一个且呈环状结构;又或者,第一限位片A1813可以至少设有三个,三个第一限位片A1813沿盖体A1812的内环壁A18121的周向方向间隔设置。具体地,关于第一限位片A1813的数量以及形状,在此可不做具体限制。
在一实施例中,如图12和图13所示,第一限位片A1813一体成型于盖体A1812,换言之,盖体A1812与第一限位片A1813为一体成型结构。当然,在其他实施例中,第一限位片A1813可通过粘接、铆接等方式连接至盖体A1812上。
参见图7和图12,在一实施例中,所述防护壳A181还包括第二限位片A1814。第二限位片A1814设于盖体A1812的另一侧(即朝向第二定位组件A120的一侧)并与盖体A1812的内环壁A18121呈夹角设置。第一限位片A1813、盖体A1812的内环壁A18121以及第二限位片A1814依次围合形成卡持凹部A1811。
在一实施例中,第二限位片A1814可一体成型于盖体A1812上。或者,在其他实施例中,第二限位片A1814可通过粘接、铆接等方式连接于盖体A1812上。具体地,如图13所示,防护机构A180还包括连接件(图中未示出)。盖体A1812设有第一连接部A1812e,第二限位片A1814设有第二连接部A18141,连接件连接第一连接部A1812e和第二连接部A18141。其中,第一连接部A1812e和第二连接部A18141上均设有连接孔,连接件可为螺钉或螺栓等,这样,连接件可穿过两个连接孔并通过螺纹连接的方式以限制第二限位片A1814脱离盖体A1812。在一实施例中,第二限位片A1814设有多个,多个第二限位片A1814沿内环壁A18121的周向方向间隔设置。具体地,在本实施例中,第二限位片A1814设有四个,四个第二限位片A1814分别位于呈方形结构的盖体A1812的四角(见图7)。当然,在其他实施例中,第二限位片A1814可为环形结构,第二限位片A1814的中心与盖体A1812的内环壁A18121的圆心同轴设置。
参见图5至图7,在一实施例中,每一槽型结构A1212内均活动设有一锁舌A190,防护壳A181的两个第一相切部A1812a分别设有第一锁定孔A1815,第一定位组件A110的前后端分别设有第二锁定孔(图中未示出)。当第一定位组件A110转动至朝向于第一方向F1时,至少一个锁舌A190能够穿过对应的第一锁定孔A1815以及第二锁定孔,以实现第一定位组件A110在朝向于第一方向F1时的锁定。
在上述的定位组件A100中,第一定位组件A110可转动地设置于第二定位组件A120上,当第一定位组件A110相对于第二定位组件A120转动至朝向于第二方向F2时,第一定位组件A110可相对于第二定位组件A120沿第二方向F2向外拉出,因此,当载具本体A200安装于第一定位组件A110上,且载具本体A200随第一定位组件A110朝向于第二方向F2时,载具本体A200会沿第二方向F2向外拉出,这样,方便用户抱进或抱出婴幼儿。此外,在上述的定位组件A100中,第一定位组件A110位于第二定位组件A120上设置的两个凸体A121之间,当第一定位组件A110相对于第二定位组件A120沿第二方向F2向外拉出时,防护壳A181的部分边缘仍插设在两个槽型结构A1212内,这样,防护壳A181能够有效遮挡住第一定位组件A110与凸体A121之间的间隙,确保用户在操作过程中无法将手部伸入该间隙,从而有效预防夹手的风险。同时,还增加了第一定位组件A110的支撑点数量,使第一定位组件A110在转动至侧向(例如左侧或右侧)时,不仅能受到来自第一滑动件A141和第二滑动件A142的支撑,还能通过防护壳A181卡设于槽型结构A1212内的方式受到额外的支撑,从而提高了第一定位组件A110转动至侧向时的稳定性。
本申请第二方面提供了一种载具,包括载具本体B300(见图26)以及根据本发明一些实施例提供的定位组件B100。其中,载具本体B300例如可以是座椅、提篮或睡箱等等。下文在对载具进行描述的同时,将一并对载具本体B300和定位组件B100进行说明。
图14和图15示出了根据本申请第二方面一实施例提供的定位组件B100的立体图,该定位组件B100用于将载具本体B300(见图26)安装至汽车座椅(图中未示出)上,以实现儿童或婴幼儿的安全出行。具体地,定位组件B100可以包括第一定位组件B110以及第二定位组件B120。下文将对第一定位组件B110以及第二定位组件B120进行详细说明。
在一实施例中,第二定位组件B120上设有轨道,第一定位组件B110上设有滑动件,滑动件沿轨道滑移以使第一定位组件B110相对于第二定位组件B120进行旋转和滑移。具体地,如图15和图16所示,轨道包括第一轨道B131和第二轨道B132,第一轨道B131沿第一方向F1延伸,第二轨道B132沿第二方向F2延伸,第二方向F2与第一方向F1相交错。滑动件包括沿第一定位组件B110前后方向(即Q1、Q2方向)间隔设置的第一滑动件B141和第二滑动件B142(可参见图23和图24,具体结构可参见后文)。其中,第一滑动件B141沿第一轨道B131或第二轨道B132中的一者滑移,第二滑动件B142沿第一轨道B131或第二轨道B132中的另一者滑移。例如,第一滑动件B141沿第一轨道B131滑移,第二滑动件B142沿第二轨道B132滑移。或者,第一滑动件B141沿第二轨道B132滑移,第二滑动件B142沿第一轨道B131滑移。这样,可使第一定位组件B110相对于第二定位组件B120的转动而同时进行位移。
参见图14和图15,在一实施例中,第一定位组件B110用于连接载具本体B300,第二定位组件B120用于连接汽车座椅。具体地,第一定位组件B110上设有第一连接机构B170(详见后文),第一连接机构B170用于与载具本体B300底部的卡合件B310(见图26)连接。第二定位组件B120上设有座椅连接机构B180(如ISOFIX连接器)以及支撑腿B190,座椅连接机构B180主要用于将第二定位组件B120固定至汽车座椅上,支撑腿B190主要用于抵靠车辆内部的地板。这样,当定位组件B100安装至汽车座椅上,且载具本体B300安装至定位组件B100后,可通过转动第一定位组件B110的方式改变载具本体B300的朝向,使得载具本体B300具有不同的使用模式。需要说明是,载具本体B300的朝向取决于第一轨道B131和第二轨道B132的延伸方向。当第一轨道B131沿第一方向F1延伸,第二轨道B132沿第二方向F2延伸时,载具本体B300则具有朝向于第一方向F1和第二方向F2的使用模式。具体地,第一方向F1与第二方向F2相垂直,即可视为第一轨道B131与第二轨道B132相垂直。将第一轨道B131与第二轨道B132两者的交叉点称为交叉中心B133(见图16)。
在一实施例中,第一定位组件B110整体大致呈圆盘状结构,第一滑动件B141设置在第一定位组件B110的圆心处,第二滑动件B142偏离圆心设置。需要说明的是,第一定位组件B110大致呈圆盘状结构时,第一定位组件B110的圆心即为其几何中心。当然,在其他实施例中,第一定位组件B110可以是其他对称形状(例如椭圆形、矩形等),第一滑动件B141可以设置在第一定位组件B110的几何中心或偏离几何中心的位置;又或者,第一定位组件B110还可以是不对称的形状。在本实施例中,第一滑动件B141沿第二轨道B132滑移,第二滑动件B142沿第一轨道B131滑移。当第一定位组件B110相对第二定位组件B120转动至朝向于第一方向F1时,载具本体B300处于朝向于第一方向F1的使用模式,此时,第一滑动件B141位于交叉中心B133,第二滑动件B142位于第一轨道B131。此时可以理解为,第一定位组件B110的圆心(即第一定位组件B110的几何中心)与第二定位组件B120的几何中心同轴设置。当第一定位组件B110相对第二定位组件B120转动至朝向于第二方向F2时,载具本体B300处于朝向于第二方向F2的使用模式,此时,第二滑动件B142位于交叉中心B133,第一滑动件B141位于第二轨道B132,第一定位组件B110整体相对于第二定位组件B120沿第二方向F2位移。具体地,第一定位组件B110相对于第二定位组件B120沿第二方向F2向外拉出。需要说明的是,“第一定位组件B110相对于第二定位组件B120沿第二方向F2向外拉出”是指第一定位组件B110沿着第二方向F2相对于第二定位组件B120的一侧位移以更靠近这一侧的车门,而非脱离第二定位组件B120。具体而言,是指第一定位组件B110会向第二定位组件所安装汽车座椅对应的一侧移动,更靠近该侧车门。例如,若第二定位组件B120安装在左侧座椅,第一定位组件B110转动至朝向于左侧方向时,第一定位组件B110会更靠近左侧车门。若第二定位组件B120安装在右侧座椅,第一定位组件B110转动至朝向于右侧方向时,第一定位组件B110会更靠近右侧车门。若第二定位组件B120安装在中间座椅,第一定位组件B110转动至朝向于两侧车门中的任一侧时,第一定位组件B110都会更靠近对应侧的车门。以上情况均视为第一定位组件B110沿着第二方向F2相对于第二定位组件B120的一侧向外位移。此时,第一定位组件B110的几何中心相对于第二定位组件B120的几何中心沿第二方向F2的一侧位移。此外,还需要说明的是,“第一定位组件B110相对于第二定位组件B120沿第二方向F2向外拉出”并不限定为必须通过“拉”这一动作来使第一定位组件B110相对于第二定位组件B120沿第二方向F2位移,只要能达成第一定位组件B110相对于第二定位组件B120产生此方向位移的动作,均符合该表达含义。这样,方便用户从载具本体B300内抱出儿童或将儿童抱进载具本体B300内。
需要说明的是,在本实施例中,第一定位组件B110具有前端和后端,为了清楚理解第一定位组件B110的各端部,以载具本体B300安装至第一定位组件B110上为例,载具本体B300的前后方向与第一定位组件B110的前后方向相平行。具体地,当婴幼儿或儿童乘坐于载具本体B300内时,第一定位组件B110的前端相对于后端更靠近婴幼儿或儿童的脚部,反之,第一定位组件B110的后端相对于前端更靠近婴幼儿或儿童的头部。当第一定位组件B110朝向于某一方向时,即意味着载具本体B300也朝向该同一方向;同时,乘坐于载具本体B300内的儿童亦朝向该同一方向。为了直观了解载具本体B300以及第一定位组件B110的前后方向,各附图中分别用箭头Q1和Q2示意性示出前方向和后方向,Q1方向与Q2方向平行且相反。
还需要说明的是,在本实施例中,当定位组件B100(第二定位组件B120)安装于汽车座椅上时,第一方向F1是指汽车的前后方向,第二方向F2是指汽车的左右方向。更具体地,在本实施例中,第一方向F1包含了两个方向(即前方向和后方向),这两个方向平行且相反。同样地,第二方向F2也包含了两个方向(即左侧方向和右侧方向),这两个方向平行且相反。为了便于区分汽车的前方向、后方向、左侧方向和右侧方向,在各附图中分别用箭头F和B示意性示出前方向和后方向,分别用箭头L和R示意性示出左侧方向和右侧方向。因此,前文所提第一定位组件B110相对于第二定位组件B120转动至朝向于第一方向F1是指第一定位组件B110的前端朝向于第一方向F1(可以指朝向F方向或B方向);第一定位组件B110相对于第二定位组件B120转动至朝向于第二方向F2是指第一定位组件B110的前端朝向于第二方向F2(可以指朝向R方向或L方向)。
需要说明的是,本申请的涉及的这些方位术语仅表示相对位置关系,用于使本申请实施例的描述更加清楚,并不用于对本申请的保护范围产生不当限定。
在一实施例中,第一轨道B131和第二轨道B132均被交叉中心B133分割形成两个轨段。例如第一轨道B131被交叉中心B133分割形成第一轨段B1311和第二轨段B1312,第二轨道B132被交叉中心B133分割形成第三轨段B1321和第四轨段B1322(见图16)。其中,第一轨段B1311由交叉中心B133沿第一方向F1向汽车的车头方向延伸,即第一轨段B1311由交叉中心B133沿F方向延伸,第二轨段B1312由交叉中心B133沿第一方向F1向汽车的车尾方向延伸,即第二轨段B1312由交叉中心B133沿B方向延伸;第三轨段B1321由交叉中心B133沿第二方向F2向汽车的左侧方向延伸,即第三轨段B1321由交叉中心B133沿L方向延伸,第四轨段B1322由交叉中心B133沿第二方向F2向汽车的右侧方向延伸,即第四轨段B1322由交叉中心B133沿R方向延伸。这样,载具本体B300在随第一定位组件B110相对第二定位组件B120转动后,具有向前、向后、向左以及向右四种使用模式。
参见图16和图17,在一实施例中,第二定位组件B120包括顶盖B121以及底盖B122,顶盖B121与底盖B122上下连接并围合形成一第二安装腔B123。第一轨道B131和第二轨道B132均设于顶盖B121上并与第二安装腔B123相连通。在一实施例中,顶盖B121的上表面沿第一方向F1间隔设有两个凸体,两个凸体可分别称为第一凸体B124和第二凸体B125,第一凸体B124和第二凸体B125之间形成了安装空间B126,第一轨道B131和第二轨道B132均位于安装空间B126内,第一定位组件B110可转动地设置在安装空间B126内。具体地,当第二定位组件B120安装在汽车座椅上时,第一凸体B124相对第二凸体B125更靠近汽车车头,即可视为第一凸体B124沿汽车行驶方向位于第二凸体B125的前方。更具体地,如图16和图18所示,第一凸体B124和第二凸体B125上均形成有限位凸部B127,且限位凸部B127朝向于安装空间B126突出。第一凸体B124上的限位凸部B127以及第二凸体B125上的限位凸部B127均与第二定位组件B120的上表面(即顶盖B121的上表面)形成一具有开口的槽型结构B270。这样,当第一定位组件B110容置在安装空间B126内并朝向于第一方向F1时,第一定位组件B110周向的部分边缘能够插入这两个槽型结构B270中(对比图14和图15)。这样,槽型结构B270可以限制第一定位组件B110及载具本体B300大致在竖直方向上(即可视为垂直于第一方向F1和第二方向F2所在平面的方向)的晃动,而允许第一定位组件B110在水平方向(即可视为第一方向F1和第二方向F2所在平面)的旋转和滑动。当汽车发生碰撞或紧急刹车时,载具本体B300在惯性力的作用下具有向前(即相当于向汽车车头方向)倾翻的趋势,进而造成第一定位组件B110具有脱离第二定位组件B120的趋势。而将第一定位组件B110周向的部分边缘插入在这两个槽型结构B270内,槽型结构B270能够对第一定位组件B110进行抵压,进而能够防止载具本体B300和第一定位组件B110脱离第二定位组件B120,提升了载具的使用安全性。
参见图19至图22,在一实施例中,第一定位组件B110上形成有避让凹陷B210,第一定位组件B110可以借由避让凹陷B210以避免第一定位组件B110在安装空间B126内相对第二定位组件B120在旋转过程中与第一凸体B124和第二凸体B125发生干涉。具体地,当第一定位组件B110相对于第二定位组件B120转动至朝向于第一方向F1时,避让凹陷B210的底部能够插入槽型结构B270内,避让凹陷B210的侧壁与第一凸体B124的限位凸部B217之间留有间距。具体地,第一定位组件B110可以包括支撑底座B111和连接座B112。其中支撑底座B111大体呈圆盘状结构,连接座B112大致呈条形,连接座B112相对于支撑底座B111的上表面凸设在支撑底座B111上,且当第一定位组件B110转动至朝向于第一方向F1时,连接座B112可视为沿第一方向F1延伸,当第一定位组件B110转动至朝向于第二方向F2时,连接座B112可视为沿第二方向F2延伸。支撑底座B111的圆心大致与连接座B112的几何中心同轴设置,且支撑底座B111的直径大于连接座B112的长度,支撑底座B111相对于连接座B112沿连接座B112长度方向的突出部分可视为上述避让凹陷B210的底部,同时也可视为上述第一定位组件B110所指的可用于插设在槽型结构270内的部分边缘,而连接座B112朝向于其延伸方向的侧壁即可视为避让凹陷B210的侧壁。更具体地,当第一定位组件B110相对第二定位组件B120转动至朝向于第一方向F1时,避让凹陷B210的侧壁与第一凸体B124的限位凸部B127之间的间距M2(见图22)不小于10mm,例如M2为10mm、11mm、12mm、13mm等等;或者,避让凹陷B210的侧壁与第一凸体B124的限位凸部B127之间的间距M2不大于5mm,例如M2为5mm、4mm、2mm等等。这样,当用户将第一定位组件B110相对第二定位组件B120转动至朝向于前方或后方的过程中,可以避免第一定位组件B110与第一凸体B124的限位凸部B127之间的空间夹伤用户的手部等部位,提高了定位组件B100使用的安全性。
参见图23至图26,在一实施例中,第一连接机构B170设置在第一定位组件B110上并具有锁止状态和解锁状态。具体地,第一连接机构B170设置在连接座B112上。当第一连接机构B170处于锁止状态时,第一连接机构B170与载具本体B300连接。当第一连接机构B170处于解锁状态时,第一连接机构B170与载具本体B300拆卸脱离。具体地,载具本体B300的底部设有卡合件B310(如卡合杆,见图26)。第一连接机构B170包括卡合钩B171和设于连接座B112上的卡槽B1121,卡槽B1121用于容置载具本体B300底部的卡合件B310,卡合钩B171枢接于连接座B112上并具有锁止位置和释锁位置。当卡合钩B171位于锁定位置时,卡合钩B171至少部分伸入卡槽B1121内以与载具本体B300的卡合件B310卡合锁定。更具体地,第一定位组件B110内具有第一安装腔B113,卡槽B1121的槽壁设有通孔B1122(见图20),通孔B1122连通第一安装腔B113和卡槽B1121。如图27和图28所示,第一安装腔B113内设有支撑架B114,卡合钩B171通过枢转轴B115枢接于支撑架B114。当卡合钩B171位于锁定位置时,卡合钩B171至少部分穿过通孔B1122并伸入卡槽B1121内(见图23和图24)以与卡合件B310卡合锁定。当卡合钩B171位于释锁位置时,卡合钩B171通过通孔B1122退离卡槽B1121(见图25)。
在本实施例中,如图19、图20和图26所示,载具本体B300的底部通常沿前后方向设有两个卡合件B310,连接座B112上形成有两排卡槽B1121。其中,每排卡槽B1121至少包括一个卡槽B1121。具体地,如图19和图20所示,每排卡槽B1121包括两个卡槽B1121。换言之,第一定位组件B110上形成有四个卡槽B1121,四个卡槽B1121呈矩形排布,且沿前后设置的两排卡槽B1121的距离等于载具本体B300底部两个卡合件B310之间的距离。对应地,第一定位组件B110上枢接有四个卡合钩B171,每一卡槽B1121对应一卡合钩B171。
参见图17至图19,在一实施例中,定位组件B100还包括锁定保持机构B230。锁定保持机构B230可移动地设置于第一定位组件B110并用于保持第一连接机构B170与载具本体B300的连接。具体地,锁定保持机构B230活动设置于第一安装腔B113内,当卡合钩B171被驱动至锁定位置时,锁定保持机构B230用于将卡合钩B171锁定在锁定位置。
继续参见图17至图19,在一实施例中,锁定保持机构B230包括第一锁定件B231。第一锁定件B231可移动地设置在第一安装腔B113内并具有第一位置和第二位置。具体地,当第一定位组件B110朝向于第一方向F1时,第一锁定件B231的移动方向与第一方向F1平行;当第一定位组件B110朝向于第二方向F2时,第一锁定件B231的移动方向与第二方向F2平行。第一锁定件B231的大致沿水平方向移动。当第一锁定件B231处于第一位置时,第一连接机构B170处于锁止状态;当第一锁定件B231处于第二位置时,第一连接机构B170处于释锁状态。在一实施例中,第一锁定件B231和卡合钩B171两者中其中一者设有锁定凹槽B2311,另一者设有卡合部B1711。具体地,如图23所示,在本实施例中,卡合钩B171设有卡合部B1711,第一锁定件B231设有锁定凹槽B2311。更具体地,当第一锁定件B231处于第一位置时,卡合部B1711与锁定凹槽B2311卡合以将卡合钩B171锁定在锁定位置(见图23和图24),这样,使得第一连接机构B170处于锁止状态。当第一锁定件B231位于第二位置时,卡合部B1711与锁定凹槽B2311分离以允许卡合钩B171在锁定位置和释锁位置件之间切换,这样,使得第一连接机构B170处于释锁状态。需要说明的是,在本实施例中,如图23和图28所示,第一锁定件B231上设有四个锁定凹槽B2311,每一锁定凹槽B2311用于分别与每一卡合钩B171的卡合部B1711对应配合锁定。
参见图27和图28,在一实施例中,锁定保持机构B230还包括第三复位件B232,第三复位件B232用于为第一锁定件B231提供弹性复位力,以使第一锁定件B231保持在第一位置。第三复位件B232例如是弹簧,这样,如图23至图25所示,当卡合钩B171由释锁位置枢转至锁定位置时,在第三复位件B232的作用下,可使第一锁定件B231自动切换至第一位置,以使第一锁定件B231的锁定凹槽B2311能够与卡合钩B171的卡合部B1711相卡合以锁定卡合钩B171,并使卡合钩B171保持在锁定位置,这样,提高了载具本体B300安装至第一定位组件B110上的稳定性和可靠性。
在一实施例中,第一连接机构B170还包括第二复位件(图中未示出),第二复位件用于将卡合钩B171保持在释锁位置。第二复位件例如是扭簧,扭簧套设在枢转轴B115上并与卡合钩B171相抵。这样,当第一锁定件B231移动至第二位置时,卡合钩B171可自动绕枢转轴B115转动以处于释锁位置,从而方便顺畅地进行释锁,不易出现卡合钩B171锁死的问题。
参见图24、图25以及图30,在一实施例中,定位组件B100还包括可移动地设于第一定位组件B110上的第一释锁件B240,以方便用户操控第一锁定件B231。第一释锁件B240与第一锁定件B231驱动配合。第一释锁件B240可被操作以驱动第一锁定件B231从第一位置向第二位置移动。这样,用户可通过操控第一释锁件B240即可使第一锁定件B231由第一位置向第二位置切换。具体地,第一释锁件B240设有驱动斜面B241,该驱动斜面B241沿第一释锁件B240的移动方向倾斜地延伸。第一锁定件B231还设有驱动部B2312,驱动部B2312适于被驱动斜面B241抵推并沿驱动斜面B241滑动,以使第一锁定件B231能够在第一位置和第二位置之间切换。更具体地,第一释锁件B240可在第一定位组件B110上大致沿竖直方向上下移动,第一释锁件240的移动方向与第一锁定件B231相交,可选地,第一释锁件B240的移动方向与第一锁定件B231的移动方向相垂直。
参见图24和图25,简单说明第一释锁件B240与第一锁定件B231之间的配合关系。具体地,当第一锁定件B231处于第一位置时,第一锁定件B231的驱动部B2312与第一释锁件B240的驱动斜面B241的顶端相抵。当沿竖直方向向上推动第一释锁件B240时,在驱动斜面B241的导向驱动下,使得驱动部B2312在驱动斜面B241上的相对位置逐渐由驱动斜面B241的顶端向驱动斜面B241的底端切换,进而使得第一锁定件B231由第一位置移动至第二位置,从而卡合部B1711能从锁定凹槽B2311内脱离。
参见图24、图25、图28和图29,在一实施例中,定位组件B100还包括第二释锁件B250,该第二释锁件B250可移动地设于第一定位组件B110上并具有开锁位置和闭锁位置。第二释锁件B250同样与第一锁定件B231驱动配合。当第二释锁件B250处于闭锁位置时,第一锁定件B231处于第一位置。当第二释锁件B250处于开锁位置时,第一锁定件B231处于第二位置。如此,用户也可通过操作第二释锁件B250控制第一锁定件B231的位置。需要说明的是,在本实施例中,第二释锁件B250的移动方向与第一锁定件B231的移动方向相平行。当第一定位组件B110朝向于第一方向F1时,第二释锁件B250的移动方向平行于第一方向F1;当第一定位组件B110朝向于第二方向F2时,第二释锁件B250的移动方向平行于第二方向F2。
结合图28至图32,在一实施例中,第二释锁件B250设有抵推部B251,第一锁定件B231还设有顶推部B2313,抵推部B251与顶推部B2313驱动配合,第二操作件B250可被操作以驱动第一锁定件B231由第一位置向第二位置切换。具体地,抵推部B251和顶推部B2313两者中的一者可以为凹部,另一者为凸部,两者插接以驱动配合。例如,在本实施例中,抵推部B251包括抵推凹部B2511,抵推凹部B2511朝向于顶推部B2313并沿第二释锁件B250的移动方向延伸,顶推部B2313活动插设于抵推凹部B2511内。当第二释锁件B250被操作并由闭锁位置向开锁位置移动时,第二释锁件B250通过抵推凹部B2511的后侧壁B2511a驱动顶推部B2313移动以带动第一锁定件B231由第一位置向第二位置切换。
在一实施例中,如图29和图32所示,第二释锁件B250还设有导向槽B252,导向槽B252沿第二释锁件B250的移动方向延伸。第一安装腔B113内设有导向柱B116,且导向柱B116插设于导向槽B252内,通过导向柱B116与导向槽B252的导向配合,可避免第二释锁件B250移动时发生偏移。在本实施例中,导向槽B252的数量为两个,两个导向槽B252分布在第二释锁件B250的左右两侧。导向柱B116的数量为两个,两个导向柱B116分别与对应的导向槽B252导向配合。进一步地,每一导向槽B252内设有一弹性件B254,该弹性件B254主要用于为第二释锁件B250供弹性回复力,以使第二释锁件B250保持在闭锁位置。
如图24、图25以及图29所示,在一实施例中,第二释锁件B250上设有握持凹部B253。这样,当用户需要操作(如拉动)第二释锁件B250时,可将手指放入握持凹部B253以便快速拉动第二释锁件B250进行移动。
结合图15、图23、图29和图32,以第一定位组件B110沿第二方向F2朝向于汽车右侧方向(即R方向)为例,简单说明第二释锁件B250与第一锁定件B231之间的配合关系。具体地,当第一锁定件B231处于第一位置时,第一锁定件B231的顶推部B2313与第二释锁件B250的抵推凹部B2511的后侧壁B2511a相抵(见图29)。当沿第二方向F2向右拉动第二释锁件B250时,第二释锁件B250的抵推凹部B2511的后侧壁B2511a抵推第一锁定件B231的顶推部B2313,以推动顶推部B2313沿第二方向F2向右移动,进而使得第一锁定件B231移动至第二位置,从而卡合部B1711能从锁定凹槽B2311内脱离。
在一实施例中,第一释锁件B240和第二释锁件B250沿第一定位组件B110的周向方向相对设置(见图19和图20)。具体地,第一释锁件B240和第二释锁件B250沿第一锁定件B231的移动方向相对设置(见图27和图28)。在本实施例中,第二释锁件B250位于前排卡合钩B171(或卡槽B1121)附近,第一释锁件B240位于后排卡合钩B171(或卡槽B1121)附近。具体地,第一释锁件B240位于连接座B112延伸方向的后端,即第一释锁件B240可视为位于第一定位组件B110的后端,更具体地,第一释锁件B240位于避让凹陷B210附近。第二释锁件B250位于连接座B112延伸方向的前端,即第二释锁件B250可视为位于第一定位组件B110的前端。第一释锁件B240和第二释锁件B250均与第一锁定件B231驱动配合。这样,如图15所示,当载具本体300(如提篮,见图26)随第一定位组件B110相对于第二定位组件B120转动朝向于第二方向F2时,即第一定位组件B110相对于第二定位组件B120转动至侧向(左侧方向或右侧方向)时,第二释锁件B250随第一定位组件B110相对于第二定位组件B120在第二方向F2向外拉出,以朝侧向(即左侧或右侧)突出,以更靠近侧边的车门,同时面朝用户,以便于用户操作,用户则可通过位于第一定位组件B110前端的第二释锁件B250控制第一连接机构B170的状态;换句话说,用户可通过第二释锁件B250控制卡合钩B171所处的位置,以便将载具本体B300从第一定位组件B110上取下。在一实施例中,当第一定位组件B110相对于第二定位组件B120转动朝向于第二方向F2时,即为第一定位组件B110的前端朝向于第二方向F2,由于第二释锁件B250位于第一定位组件B110的前端,第二释锁件B250随第一定位组件B110相对于第二定位组件B120在第二方向F2向外拉出,使得第二释锁件B250处于更靠近侧边车门的位置。这样,在侧向时拆卸载具本体B300的过程中,用户无需操作位于后端且距离更远的第一释锁件B240进行释锁,而是可以直接操作位于前端的第二释锁件B250,如此,可以使用户在拆卸载具本体B300时更加方便快捷。需要说明的是,由于第二释锁件B250设置在第一定位组件B110上,因此,当第一定位组件B110相对于第二定位组件B120进行旋转和滑移时,第二释锁件B250会随之相对于第二定位组件B120移动。基于此,“第二释锁件B250随第一定位组件B110相对于第二定位组件B120在第二方向F2向外拉出”可以理解为:第二释锁件B250随第一定位组件B110一同转动,并最终也朝向第二方向F2且随第一定位组件B110会更靠近车门,方便用户操作。需要说明的是,这里并非指第二释锁件B250本身发生了移动,而是在第一定位组件B110的带动下同步产生的位置变化。
需要说明的是,当载具本体B300为座椅时,第二释锁件B250会被座椅所遮挡,此时,用户可通过第一释锁件B240释锁卡合钩171。当载具本体B300为提篮时,第二释锁件B250外露,因此,当提篮随第一定位组件B110转动至第二方向F2使用时,用户可通过单手操作(如拉动)第二释锁件B250的方式释锁卡合钩B171,另一只手则可同时将提篮从第一定位组件B110上取下,提高了操作的便捷性。
通常,当第一定位组件B110相对于第二定位组件B120转动至朝向于第一方向F1时,在拆卸载具本体B300时,用户一般位于定位组件B100的侧面(如左侧或右侧),此时,用户可操作第一释锁件B240或第二释锁件B250中的任一者均可。例如,当用户需要通过第一释锁件B240控制第一连接机构B170的状态时,用户可沿竖直方向向上推动第一释锁件B240,驱动斜面B241随之向上移动,在驱动斜面B241的导向驱动下,驱动部B2312在驱动斜面241上的相对位置逐渐由驱动斜面B241的顶端向驱动斜面B241的底端切换,进而推动整个第一锁定件B231向前移动以切换至第二位置,同时,卡合部B1711退离锁定凹槽B2311,卡合钩B171在第二复位件的作用下自动切换至释锁位置,这样,卡合件B310可脱离卡合钩B171。需要说明的是,当第一锁定件B231位于第一位置时,顶推部B2313沿抵推凹部B2511的延伸方向位于抵推凹部B2511的后侧壁B2511a处(如图29),顶推部B2313与抵推凹部B2511的前侧壁B2511b之间留有移动间隙,因此,当驱动斜面B241推动第一锁定件B231向第二位置移动的过程中,顶推部B2313在移动间隙内移动,只有当第一锁定件B231的移动行程(相当于第一位置和第二位置之间的距离)大于移动间隙的长度时,顶推部B2313会带动第二释锁件B250由闭锁位置向开锁位置移动。而当第一锁定件B231的移动行程小于或等于移动间隙的长度时,按压第一释锁件B240以拆卸载具本体B300的过程中,第二释锁件B250保持相对固定。或者,又例如,当用户需要通过第二释锁件B250控制第一连接机构B170的状态时,用户可沿水平方向向外拉动第二释锁件B250,以使第二释锁件B250由闭锁位置向开锁位置移动。第二释锁件B250在移动过程中,抵推凹部B2511随之移动,顶推部B2313与抵推凹部B2511的后侧壁B2511a相抵,以带动第一锁定件B231由第一位置向第二位置移动,这样,卡合部B1711可退离锁定凹槽B2311,卡合钩B171在第二复位件的作用下自动切换至释锁位置。需要说明的是,第二释锁件B250带动第一锁定件B231移动过程中,驱动部B2312会随第一锁定件B231移动以逐渐远离驱动斜面B241,而此过程中,第一释锁件B240保持相对固定。
请结合图27、图28和图31,在一实施例中,第一定位组件B110设有释锁指示机构B290,该释锁指示机构B290能够依据第一锁定件B231在第一安装腔B113内的位置,直接反映卡合钩B171处于锁止位置还是释锁位置。具体地,如图27所示,释锁指示机构B290包括摆动件B291、色块B292以及观察孔B293。其中,摆动件B291设置于第一安装腔B113内并与支撑底座B111的底壁枢接且形成第一枢转点Q1,摆动件B291的一端与第一锁定件B231枢接。当第一锁定件B231在第一位置和第二位置件切换时,第一锁定件B231可带动摆动件B291绕第一枢转点Q1摆动。更具体地,摆动件B291的另一端设有色块B292(例如绿色或红色等)。支撑底座B111的顶壁上设有观察孔B293。结合前文可知,当操作第一释锁件B240或第二释锁件B250时,第一锁定件B231会由第一位置向第二位置移动,此时摆动件B291与第一锁定件B231枢接的一端随第一锁定件B231移动,以使整个摆动件B291枢转,进而可使摆动件B291设有色块B292的另一端移动,这样,用户可通过观察孔B293处是否显示有色块B292,来判断第一锁定件B231的位置,从而推断出卡合钩B171所处的位置。具体地,在本实施例中,当第一锁定件B231处于第一位置时,色块B292与观察孔B293相对,那么,用户可通过观察孔B293查看到色块B292。而当第一锁定件B291处于第二位置时,色块B292则会与观察孔B293错位,用户无法通过观察孔B293查看到色块B292。因此,当通过观察孔B293查看到色块B292时,则表明卡合钩B171处于锁止位置;当通过观察孔B293未查看到色块B292时,则表明卡合钩B171处于释锁位置。当然,在其他实施例中,第一锁定件B291处于第一位置时,色块B292与观察孔B293错位,用户无法通过观察孔B293查看到色块B292,而当第一锁定件B231处于第二位置时,色块B292与观察孔B293相对,用户可通过观察孔B293查看到色块B292。又或者,每一个摆动件B291上都设置有两种不同颜色的色块B292(例如绿色和红色),两种颜色的色块B292分别对应第一锁定件B231处于第一位置和第二位置,如此,用户通过观察孔B293查看色块B292的颜色,来判断卡合钩B171处于锁止位置还是释锁位置。
请结合图17和图33,在一实施例中,第二定位组件B120的第二安装腔B123内还可以设有第一支撑机构B128,一方面,当载具本体B300连接于第一定位组件B110上,且第一定位组件B110相对于第二定位组件B120转动至朝向第一方向F1时,第一支撑机构B128用于辅助支撑载具本体B300,以提高载具本体B300安装于第一定位组件B110上的稳定性。另一方面,本实施例的第一支撑机构B128至少部分位于第一凸体B124以及第二凸体B125两者的槽型结构B270内,本实施例的第一支撑机构B128可用于加强前文中用于卡合第一定位组件B110的槽型结构B270的槽壁强度。本实施例中,第一支撑机构B128有两个且分别设置于第一凸体B124和第二凸体B125处。
下面以位于第二定位组件B120的后端的第一支撑机构B128为例具体描述其结构。结合图17、图33至图35,第一支撑机构B128可以包括第一支撑件B1281和第二支撑件B1282。本实施例中,如图34和图35所示,第二定位组件B120还包括设置于第二安装腔B123内的骨架B129,该骨架B129大致呈U型结构且包括沿第二定位组件B120的前后方向(即第一方向F1)延伸且沿左右方向(即第二方向F2)间隔设置的第一直杆B1291和第二直杆B1292,以及两端分别连接于第一直杆B1291和第二直杆B1292之间的弧形杆B1293。本实施例中,位于第二定位组件B120的后端的该第一支撑件B1281为U型杆且该第一支撑件B1281的两端分别固定于第一直杆B1291和第二直杆B1292上。第二支撑件B1282有一个且设置于第一支撑件B1281的上表面。当然,在其他实施例中,第二支撑件B1282的数量也可以为两个或多于两个。
请一并参见图33和图35,第二支撑件B1282大致为U型框架结构且包括相对设置的两个连接片B12821,以及连接于两个连接片B12821之间的衔接片B12822。每个连接片B12821均包括连接本体B12821a和凸设于连接本体B12821a的大致中部的支撑凸部B12821b。本实施例中,连接片B12821均为一体成型结构,即支撑凸部B12821b和连接本体B12821a一体成型。在其他实施例中,连接片B12821也可以由连接本体B12821a和支撑凸部1B2821b通过焊接、铆接等方向连接而成。连接本体B12821a和支撑凸部B12821b的下表面围合成固定槽(图中未示出),第一支撑件B1281至少部分卡合于该固定槽内,以使第二支撑件B1282支撑于第一支撑件B1281。进一步地,为增加第一支撑件B1281与第二支撑件B1282的连接稳定性,连接本体B12821a位于支撑凸部B12821b下方的部分和支撑凸部B12821b的下表面与第一支撑件B1281固定连接。支撑凸部B12821b的上表面、连接本体B12821a以及衔接片B12822围合形成卡合槽B12821c。具体地,衔接片B12822包括衔接本体B12822a以及凸设于衔接本体B12822a下表面一周的抵接凸部B12822b,衔接本体B12822a的大致呈方形片状结构,沿两个连接片B12821间隔方向设置的两个抵接凸部B12822b分别与两个连接本体B12821a连接,支撑凸部B12821b的下表面、连接本体B12821a以及抵接凸部B12822b围合形成卡合槽B12821c。
本实施例中,请一并参见图16、图18和图35,第一凸体B124和第二凸体B125朝向于安装空间B126的一侧设有与第二安装腔B123连通的连通孔(附图未示出)。连通孔具体位于槽型结构B270的槽底处。第一支撑件B1281位于第二安装腔B123内,第二支撑件B1282位于支撑凸部B12821b的上表面下方的部分位于第二安装腔B123内,第二支撑件B1282位于支撑凸部B12821b的上表面上方的部分经连通孔伸出第二安装腔B123而凸出于顶盖B121的上表面。衔接片B12822的抵接凸部B12822b位于限位凸部B127的下方。可以理解的是,两个第二支撑件B1282分别形成了第一凸体B124和第二凸体B125一部分,以使得卡合槽B12821c与槽型结构B270位置对应,增加槽型结构B270的机械强度。
本实施例中,限位凸部B127(或者第一凸体B124以及第二凸体B125)一般由塑料材质制成,而第二支撑件B1282由钢性材料(例如金属片)制成,因此第二支撑件B1282可以加强限位凸部B127(或者说第一凸体B124和第二凸体B125)的结构强度。当第一定位组件B110容置在安装空间B126内时,第一定位组件B110的避让凹陷B210的底部(见图21和图22)能够插入在这两个槽型结构B270中,即插入位于第二定位组件B120的沿前后方向(即第一方向F1)的两个卡合槽B12821c内(见图18),能够进一步防止第一定位组件B110随意脱离第二定位组件B120。此外,第二支撑件B1282沿左右方向的宽度(即两个连接片B12821之间的距离)略小于第一支撑件B1281U型杆底部沿左右方向的宽度,且第二支撑件B1282沿左右方向的宽度(即两个连接片B12821之间的距离)与第一凸体B124或第二凸体B125沿左右方向的宽度相适配。如此,宽度较大的第二支撑件B1282能够提高抵接凸部B12822b与第一定位组件B110的避让凹陷B210的底部的接触面积,提高了第二支撑件B1282抵接时的强度,进而提高了第一定位组件B110安装于第二定位组件B120上的稳定性。
进一步地,如图22和图33所示,第一支撑机构B128还可以包括辅助支撑件B1283,辅助支撑件B1283设置在第二支撑件B1282内部。辅助支撑件B1283包括相互连接的支撑柱B12831以及大致呈C型结构的支撑体B12832,支撑体B12832包括依次连接且呈夹角设置的第一辅助片B12832a、第二辅助片B12832b以及第三辅助片B12832c。具体地,当辅助支撑件B1283设置在第二支撑件B1282内部时,辅助支撑件B1283位于两个连接片B12821之间,第一辅助片B12832a的上表面与支撑凸部B12821b的上表面齐平,第三辅助片B12832c的下表面与抵接凸部B12822b背离衔接本体B12822a的端部齐平,支撑柱B12831用于抵接在第一支撑件B1281和支撑体B12832之间。换句话说,第二支撑件B1282和辅助支撑件B1283共同形成了第一凸体B124或第二凸体B125的一部分,第一辅助片B12832a、第二辅助片B12832b以及第三辅助片B12832c共同围成上述槽型结构B270。当第一定位组件B110朝向于第一方向F1时,第一定位组件B110的避让凹陷B210的底部能够被支撑体B12832的第一辅助片B12832a所支撑(结合图18和图22),且能够被支撑体B12832的第三辅助片B12832c抵接,由于支撑面积以及抵接面积均得到增加,能够起到一定的泄力作用,减少单位支撑面积以及单位抵接面积所承受的压力,从而能进一步辅助支撑第一定位组件B110,即辅助支撑载具本体B300,以提高载具本体B300安装于第一定位组件B110上的稳定性。
需要说明的是,沿前后方向,位于第二定位组件B120的前端的第一支撑机构B128的结构与上述位于第二定位组件B120的后端的第一支撑机构B128的结构大致相似,区别仅在于,由于第二定位组件B120整体呈现前低后高的结构,因此位于第二定位组件B120的前端的第一支撑机构B128的第一支撑件B1281为直杆而非U型杆(见图34)。此外,需要说明的是,在一些实施例中,由于从载具本体B300的结构来看,载具本体B300的底部上用于支撑儿童臀部部位的厚度小于用于支撑儿童腿部部分的厚度,且载具本体B300底部的下表面呈倾斜状;换句话说,载具本体B300的底部呈前厚后薄的状态,且底部的下表面倾斜。为使载具本体B300安装至定位组件B100并朝向于汽车车头方向时,乘坐于载具本体B300内的儿童能够大致处于水平乘坐的状态,因此,第二定位组件B120的上表面呈前低后高的结构设置,这样,能够与载具本体B300底部的下表面大致相契合,这样,可使载具本体B300安装在定位组件B100上更稳定。此外,斜面配合的方式更加有利于载具本体B300随第一定位组件B110相对于第二定位组件B120进行旋转和滑移。当然,在其他实施例中,载具本体B300的底部可以相对于与第二定位组件B120进行平面配合,这样,位于第二安装腔B123中两个第一支撑件B1281可以均为直杆或弯杆(如U型杆)。
在一实施例中,定位组件B100还包括防误用机构B220(见图46)。其活动设于第一定位组件B110或第二定位组件B120,用于有选择性地允许或限制第一滑动件B141或第二滑动件B142的移动,从而有选择性地限制第一定位组件B110相对于第二定位组件B120的转动角度。具体地,在本实施例中,防误用机构B220包括阻挡件(图中未示出),该阻挡件活动设于第二滑动件B142在第二轨段B1312内的移动路径上,以限制第一定位组件B110相对于第二定位组件B120转动至朝向于汽车的车头方向。
在一实施例中,防误用机构B220还包括释锁组件,其设置在第二定位组件B120上并与阻挡件连接,用于驱动阻挡件退出第二轨段B1312,从而允许第二滑动件B142在第二轨段B1312的移动。具体地,如图36和图37所示,释锁组件包括操作件B221以及牵引件(图中未示出),操作件B221可移动地设置在第二定位组件B120上并具有解锁位置和锁定位置。更具体地,顶盖B121上设有一穿孔B1211(见图16和图36),操作件B221可移动设置在第二安装腔B123内,操作件B221的操作部由穿孔B1211伸出第二安装腔B123并凸设于顶盖B121的表面,这样,可方便用户操作。牵引件连接操作件B221以及阻挡件。当操作件B221由锁定位置向解锁位置切换时,操作件B221通过牵引件驱动阻挡件退出第二轨段B1312。在本实施例中,第二安装腔B123内设有一支撑板B222,操作件B221活动设于支撑板B222上。具体地,支撑板B222以及操作件B221可以为直板结构,当然,在其他实施例中,支撑板B222以及操作件B221可以为弧形结构,这样,可以提高操作件B221在支撑板B222上沿左右方向移动的顺畅性。
在一实施例中,如图28所示,定位组件B100还包括第一限制机构B260。第一限制机构B260设置在第一定位组件B110和第二定位组件B120之间。当载具本体B300为座椅时,该第一限制机构B260用于有选择性地允许或限制座椅相对第一定位组件B110脱离,即可视为第一限制机构B260用于有选择性地允许或限制第一连接机构B170在锁止状态和解锁状态之间切换。具体地,当座椅随第一定位组件B110转动至沿第一方向F1朝向于汽车车头方向时,第一限制机构B260用于限制座椅脱离第一定位组件B110。当而第一定位组件B110相对第二定位组件B120转动至沿第一方向F1朝向于汽车车尾方向以及转动至朝向于第二方向F2时,第一限制机构B260能够允许座椅脱离第一定位组件B110。更具体地,如图28所示,当第一定位组件B110朝向于汽车车头时,第一限制机构B260进入锁定保持机构B230(即第一锁定件B231)的移动路径中,限制锁定保持机构B230移动,从而将卡合钩B171保持在锁定位置。
具体地,结合图16和图21,第一限制机构B260包括第一限位凹槽B261以及第一限位件B262。第一限位凹槽B261设置在顶盖B121上,支撑底座B111的底部设有第一限位孔B1112,第一限位孔B1112与第一安装腔B113连通,第一限位件B262可移动地设置在第一安装腔B113内且至少部分第一限位件B262能经第一限位孔B1112伸出第一安装腔B113。当第一限位件B262经第一限位孔B1112伸出第一安装腔B113而插入第一限位凹槽B261时,第一限位件B262退离第一锁定件B231的移动路径,以允许卡合钩B171处于释锁位置,进而座椅被允许脱离第一定位组件B110。当第一限位件B262退离第一限位凹槽B261时,第一限位件B262位于第一锁定件B231的移动路径,以限制卡合钩B171向释锁位置切换,座椅被限制脱离第一定位组件B110。具体地,当第一定位组件B110相对第二定位组件B120转动至朝向汽车车头时,第一限位件B262退离第一限位凹槽B261。这样,使得座椅在朝向车头方向时不能从第一定位组件B110上拆除。
结合图16和图21,在一实施例中,第一限位孔B1112位于第一滑动件B141和第二滑动件B142之间,这样,使得第一限位件B262位于第一滑动件B141和第二滑动件B142之间。当第一定位组件B110相对于第二定位组件B120沿第一方向F1由朝向于汽车车尾方向转动至朝向于第二方向F2时,第一限位件B262的滑动路径与第一限位槽B261重合。具体地,第一限位孔B1112位于第一滑动件B141和第二滑动件B142的中点位置,第一限位凹槽B261例如为半圆形槽,且该半圆形槽的半径为第一限位件B262和第一滑动件B141之间的距离。需要说明的是,在本实施例中,第一滑动件B141设置在第一定位组件B110的圆心处。具体地,半圆形槽的槽口沿第一方向F1朝向汽车车尾。当第一定位组件B110相对第二定位组件B120转动朝向汽车车尾时,第一限位件B262位于第一限位凹槽B261的中点处。具体地,第一限位凹槽B261的两端分别与第三轨段B1321以及第四轨段B1322连通,第一轨段B1311、第三轨段B1321以及第四轨段B1322均被第一限位凹槽B261分割成相连通的第一区段B1341和第二区段B1342,其中,第一区段B1341相对第二区段B1342更靠近交叉中心B133。
需要说明的是,在本实施例中,虽然第二轨段B1312未被第一限位凹槽B261分割成第一区段B1341和第二区段B1342。但可以理解为,第二轨段B1312中远离交叉中心B133的部分也可以视为第二区段B1342,第二轨段B1312中靠近交叉中心B133的部分也可以视为第一区段B1341。
在一实施例中,第一滑动件B141可以包括相连接的第一滑动杆B1411以及第一滑块B1412(见图48和图49),第二滑动件B142可以包括相连接的第二滑动杆B1421以及第二滑块B1422(见图21和图22),其中,第一滑块B1412通过第一滑动杆B1411与第一定位组件B110连接,第二滑块B1422通过第二滑动杆B1421与第一定位组件B110连接。在一实施例中,第一轨道B131可以包括第一通道和第一滑槽,第二轨道B132可以包括第二通道B1323和第二滑槽B1324(见图46和图47),其中,第一通道和第二通道B1323均设置于顶盖B121的下表面,即朝向于第二安装腔B123的一侧,两者交叉并相互连通,且第一通道和第二通道B1323均与第二安装腔B123相连通。第一滑槽设置于第一通道的内部,第二滑槽B1324设置于第二通道B1323的内部,且第一滑槽和第二滑槽B1324均为贯穿顶盖B121上表面和下表面的通槽结构。具体地,当第一滑动件B141沿第二轨道B132滑移时,可视为第一滑动杆B1411滑动于第二滑槽B1324内,同时第一滑块B1412滑动于第二通道B1323内。当第二滑动件B142沿第一轨道B131滑移时,可视为第二滑动杆B1421滑动于第一滑槽内,同时第二滑块B1422滑动于第一通道内。
需要说明的是,第一滑动件B141和第二滑动件B142可以均为一体成型结构,即第一滑块B1412与第一滑动杆B1411一体成型,两者为一体结构,第二滑块B1422与第二滑动杆B1421一体成型,两者为一体结构。当然,在其他实施例中,第一滑块B1412和第一滑动杆B1411两者为不同的构件,第一滑动件B141可以由第一滑块B1412和第一滑动杆1B411通过焊接、铆接等方式连接而成;第二滑块B1422和第二滑动杆B1421两者亦为不同的构件,第二滑动件B142可以由第二滑块B1422和第二滑动杆B1421通过焊接、铆接等方式连接而成。
在一实施例中,当第一定位组件B110相对第二定位组件B120转动至沿第二方向F2朝向于左侧方向时,第一定位组件B110则相对于第二定位组件B120沿左侧方向向外拉出(见图41);当第一定位组件B110相对于第二定位组件B120转动至沿第二方向F2朝向于右侧方向时,第一定位组件B110则相对于第二定位组件B120沿右侧方向向外拉出(结合图15和图16)。结合图14至图16,当第一定位组件B110相对第二定位组件B120转动至第二方向F2以被拉出时,第二定位组件B120上的部分第一轨道B131以及部分第二轨道B132外露,例如:如图15所示,当第一定位组件B110沿第二方向F2朝向汽车右侧方向时,第一轨段B1311的第二区段B1342、第二轨段B1312的第二区段B1342、第三轨段B1321的第二区段B1342以及第三轨段B1321的部分第一区段B1341外露。结合图16和图41,当第一定位组件B110沿第二方向F2朝向汽车左侧方向时,第一轨段B1311的第二区段B1342、第二轨段B1312的第二区段B1342、第四轨段B1322的第二区段B1342以及第四轨段B1322的部分第一区段B1341外露。为避免异物落入外露的第一轨道B131和第二轨道B132而影响定位组件B100的正常使用,同时为避免第一定位组件B110在转动过程中,用户的手部等不慎伸入外露的第一轨道B131和第二轨道B132内而造成夹伤,本申请第三方面中第一实施例所提供的定位组件B100还包括遮挡机构B150(见图16)。该遮挡机构B150设置在第二定位组件B120并位于轨道(第一轨道B131以及第二轨道B132)处,遮挡机构B150能够对轨道的至少一部分进行选择性遮挡。
参见图16、图38和图39,在一实施例中,遮挡机构B150包括遮挡件B151。具体地,该遮挡件B151包括主遮挡件B151a,该主遮挡件B151a设置在第二定位组件B120朝向于第一定位组件B110的一侧。在一实施例中,遮挡机构B150包括至少一个上述的主遮挡件B151a,第一轨段B1311、第二轨段B1312、第三轨段B1321或第四轨段B1322中的至少一者设有主遮挡件B151a。具体地,在本实施例中,主遮挡件B151a设有四个,第一轨道B131的第一轨段B1311以及第二轨段B1312分别设有一个主遮挡件B151a,第二轨道B132的第三轨段B1321以及第四轨段B1322也分别设有一个主遮挡件B151a。
下面以位于第四轨段B1322处的主遮挡件B151a为例,具体描述主遮挡件B151a的结构以及设置位置。
参见图38,在一实施例中,第二定位组件B110面朝第一定位组件B110的一侧设有限位凹部B1212,即相当于是顶盖B121背离第二安装腔B123的一侧设有限位凹部B1212,该限位凹部B1212相对于顶盖B121的上表面下陷,限位凹部B1212围绕第四轨段B1322设置。在本实施例中,限位凹部B1212围绕第四轨段B1322的部分轨段区域设置,具体地,限位凹部B1212围绕第四轨段B1322的第二区段B1342设置。因此,当一主遮挡件B151a设于限位凹部B1212内时,主遮挡件B151a能够遮挡第四轨段B1322沿长度方向延伸的部分轨段区域,即该主遮挡件B151a能够遮挡第四轨段B1322的第二区段B1342。
具体地,参见图39,主遮挡件B151a可以包括第一遮挡片B1511和第二遮挡片B1512,第一遮挡片B1511和第二遮挡片B1512分别设置在轨道相对的两侧并朝向对向延伸,第一遮挡片B1511和第二遮挡片B1512之间留有滑移缝隙B1514。滑移缝隙B1514与第四轨段B1322相连通,且滑移缝隙B1514在第二定位组件B120上的正投影位于第四轨段B1322范围内。
为防止主遮挡件B151a在安装于顶盖B121的上表面后,对第一定位组件B110与第二定位组件B120之间的转动与滑移操作产生干涉,在本实施例中,主遮挡件B151a(第一遮挡片B1511和第二遮挡片B1512)的厚度小于或等于限位凹部B1212的深度。
参见图16、图38以及图39,在一实施例中,第一遮挡片B1511和第二遮挡片B1512均包括有相连的连接部B15111和遮挡部B15112。其中,连接部B15111连接在限位凹部B1212内,遮挡部B15112则相对连接部B15111向靠近第四轨段B1322的内部方向倾斜延伸,换句话说,遮挡部B15112具有向第四轨段B1322的第二滑槽B1324内部延伸的趋势,遮挡部B15112可视为具有向斜下方延伸的趋势。这样,可以确保第二滑动件B142得以顺畅地自交叉中心B133沿第四轨段B1322向远离交叉中心B133的一端进行滑移,避免了第一遮挡片B1511和第二遮挡片B1512与第二滑动件B142发生干涉。
在一实施例中,连接部B15111可以通过粘接、卡接或铆接的方式连接在限位凹部B1212内。具体地,在本实施例中,连接部B15111通过粘接的方式连接于限位凹部B1212内。
在一实施例中,主遮挡件B151a为具有弹性的软体结构,这样,使得主遮挡件B151a具有初始状态和变形状态。具体地,第一滑动杆B1411的直径D1大于滑移缝隙B1514的宽度M1(见图39和图49),当第一滑动杆B1411位于第三轨段B1321或第四轨段B1322上的主遮挡件B151a的滑移缝隙B1514内时,在第一滑动杆B1411的挤压下,位于第三轨段B1321或第四轨段B1322上的主遮挡件B151a发生弹性形变以处于变形状态,此时,第一遮挡片B1511的遮挡部B15112和第二遮挡片B1512的遮挡部B15112在第一滑动杆B1411的挤压下相互远离。当第一滑动杆B1411从位于第三轨段B1321或第四轨段B1322上的主遮挡件B151a的滑移缝隙B1514内移出后,主遮挡件B151a复位以处于初始状态,此时,第一遮挡片B1511的遮挡部B15112与第二遮挡片B1512的遮挡部B15112相互靠近,第一遮挡片B1511与第二遮挡片B1512配合以覆盖第三轨段B1321或第四轨段B1322。需要说明的是,本实施例中第二滑动杆B1421的直径D2同样大于滑移缝隙B1514的宽度M1(见图22和图39),因此,当第二滑动杆B1421位于第一轨段B1311或第二轨段B1312上的主遮挡件B151a的滑移缝隙B1514内时,在第二滑动杆B1421的挤压下,位于第一轨段B1311或第二轨段B1312上的主遮挡件B151a发生弹性形变而处于变形状态。总而言之,可以理解为,当滑动件移入滑移缝隙B1514时,主遮挡件B151a会被挤压以处于变形状态。当滑动件移出滑移缝隙B1514时,主遮挡件B151a复位至初始状态以遮挡相应轨道。
在一实施例中,主遮挡件B151a例如可以由橡胶、硅胶、TPV、TPR、TPO、TPU、TPEE或TEP等材料制成。这样,第四轨段B1322上的主遮挡件B151a既不会阻挡第一滑动件B141沿第四轨段B1322滑移,同时,在第一滑动件B141未进入第四轨段B1322的情况下,主遮挡件B151a能够自动复位至初始状态以遮挡第四轨段B1322,从而有效降低异物落入第四轨段B1322的风险,同时,也有效减少用户手部意外伸入第四轨段B1322的概率。需要说明的是,主遮挡件B151a应不限于上述的八种材料之一制成。此外,“主遮挡件B151a能够自动复位至初始状态以遮挡第四轨段B1322”,并非指主遮挡件B151a沿第四轨段B1322宽度方向实现绝对完全覆盖以遮蔽第四轨段B1322,而是指除了滑移缝隙B1514对应第四轨段B1322所占区域外,其余部分被有效遮挡。在本实施例中,滑移缝隙B1514的宽度M1较小,甚至可以接近于0。这样,可以确保主遮挡件B151a处于初始状态对第四轨段B1322的有效遮挡。
参见图16和图39,在一实施例中,主遮挡件B151a还可以包括第一过渡片B1513,第一过渡片B1513设置在第四轨段B1322远离交叉中心B133的端部且连接第一遮挡片B1511和第二遮挡片B1512。具体地,第一过渡片B1513连接第一遮挡片B1511的连接部B15111以及第二遮挡片B1512的连接部B15111。需要说明的是,第一遮挡片B1511、第一过渡片B1513以及第二遮挡片B1512可以一体成型;当然,在其他实施例中,第一过渡片B1513也可以通过粘接等方式连接在第一遮挡片B1511和第二遮挡片B1512之间。通过第一过渡片B1513将第一遮挡片B1511和第二遮挡片B1512相连的方式,可以提高主遮挡件B151a设置在各轨段处的便捷性。
需要说明的是,在本实施例中,位于第二区段B1342处的主遮挡件B151a可以包含有第一过渡片B1513,即主遮挡件B151a包括依次连接的第一遮挡片B1511、第一过渡片B1513和第二遮挡片B1512。当然,位于第二区段B1342处的主遮挡件B151a中也可以省略第一过渡片B1513,即主遮挡件B151a仅包含相对独立的第一遮挡片B1511和第二遮挡片B1512。
当然,在其他实施例中,上述主遮挡件B151a的结构还可视为其具有滑移缝隙B1514,且滑移缝隙B1514的至少一端贯穿主遮挡件B151a,以使主遮挡件B151a形成了第一遮挡片B1511和第二遮挡片B1512。例如,滑移缝隙B1514的一端贯穿主遮挡件B151a,以将主遮挡件B151a分割以形成相连的第一遮挡片B1511和第二遮挡片B1512(图中未示出)。再或者,滑移缝隙B1514的两端均贯穿主遮挡件B151a,以将主遮挡件B151a分割以形成相互独立的第一遮挡片B1511和第二遮挡片B1512(可参见图39和图47,但图39中两个独立的第一遮挡片B1511和第二遮挡片B1512又通过第一过渡片B1513连接)。具体地,在本实施例中,主遮挡件B151a的两端均被滑移缝隙B1514贯穿。
参见图16和38,具体地,在本实施例中,第二轨段B1312远离交叉中心B133的一端、第一轨段B1311的第二区段B1342、第三轨段B1321的第二区段B1342以及第四轨段B1321的第二区段B1342均设有上述主遮挡件151a。
参见图16和图38,在一实施例,第二定位组件B120面朝第一定位组件B110的一面还设有凸起结构B280,该凸起结构B280围绕各轨道的边缘设置。具体地,该凸起结构B280相对于顶盖B121的上表面凸起,该凸起结构B280由硬质耐磨材料制成,如金属材料等。这样,当第一定位组件B110在相对第二定位组件B120沿轨道进行旋转和滑移时,凸起结构B280能够为第一定位组件B110提供滑动支撑,防止第一定位组件B110在移动过程中,第二定位组件B120的上表面(即顶盖B121的上表面)被第一定位组件B110刮花。需要说明的是,在本实施例中,凸起结构B280的高度大于主遮挡件B151a的厚度,第一限位凹槽B261的边缘亦设有凸起结构B280。
图40示出了根据本申请第三方面的第二实施例提供的一种定位组件B100的立体图,该定位组件B100可以包括第一定位组件B110、第二定位组件B120以及遮挡机构B150。本实施例中的定位组件B100是上述第一实施例的定位组件B100的变型。因此,在不冲突的情况下,本实施例中的定位组件B100的各部件的结构和部件间的连接关系以及位置关系可以参见上面第三方面的第一实施例中的描述,以下主要描述本实施例与上述第三方面的第一实施例的不同之处。
在本实施例中,遮挡件B151除了上述的主遮挡件B151a外,其还包括有辅遮挡件B151b,辅遮挡件B151b同样位于第二定位组件B120朝向第一定位组件B110的一侧。其中,主遮挡件B151a和辅遮挡件B151b分别至少设有一个。第二轨段B1312远离交叉中心B133的一端、第一轨段B1311的第二区段B1342、第三轨段B1321的第二区段B1342以及第四轨段B1322的第二区段B1342中的至少一者设有上述主遮挡件B151a,而第三轨段B1321的第一区段B1341以及第四轨段B1322的第一区段B1341中的至少一者设有上述的辅遮挡件B151b。
具体地,在本实施例中,如图40所示,第二轨段B1312远离交叉中心B133的一端、第一轨段B1311的第二区段B1342、第三轨段B1321的第二区段B1342以及第四轨段B1322的第二区段B1342分别设有主遮挡件B151a,第三轨段B1321的第一区段B1341以及第四轨段B1322的第一区段B1341分别设有辅遮挡件B151b。需要说明的是,上述的辅遮挡件B151b结构大致与主遮挡件B151a的结构可以相同,此外,辅遮挡件B151b的材料与主遮挡件B151a的材料也可以相同,因此,辅遮挡件B151b同样具有初始状态和变形状态,且当辅遮挡件B151b处于初始状态时,其能够遮挡对应的第一区段B1341。当然,在一些实施例中主遮挡件B151a和辅遮挡件B151b的结构和材料也可以不同。需要再次说明的是,“上述的辅遮挡件B151b结构大致与主遮挡件B151a的结构相同”是指当主遮挡件B151a未包括第一过渡片B1513的情况下,辅遮挡件B151b结构与主遮挡件B151a的结构相同。换句话说,本实施例中辅遮挡件B151b不包括第一过渡片B1513,使得第一区段B1341分别与第二区段B1342和交叉中心B133连通,而不干涉第一滑动件B141滑动。可以理解的是,当第一定位组件B110相对于第二定位组件B120转动至沿第二方向F2朝向右侧或左侧方向时,辅遮挡件B151b能够将外露的第三轨段B1321的第一区段B1341或第四轨段B1322的第一区段B1341遮挡(结合图15和图40)。这样,可以进一步提高第一定位组件B110相对于第二定位组件B120进行转动和滑移的可靠性,提高了定位组件B100使用的安全性和可靠性。
图41和图42示出了根据本申请第三方面的第三实施例提供的一种定位组件B100的立体图,该定位组件B100可以包括第一定位组件B110、第二定位组件B120以及遮挡机构B150’。本实施例中的定位组件B100是上述第三方面第一实施例的定位组件B100的变型。因此,在不冲突的情况下,本实施例中的定位组件B100的各部件的结构和部件间的连接关系以及位置关系可以参见上面第三方面的第一实施例中的描述,以下主要描述本实施例与上述第三方面的第一实施例的不同之处。
结合参考图42、图44和图45,本实施例中对遮挡机构B150’的结构以及设置位置进行了变型。遮挡机构B150’包括遮挡件B151’以及安装组件B152,遮挡件B151’设置在第二定位组件B120背向第一定位组件B110的一侧。具体地,遮挡件B151’通过安装组件B152固定在顶盖B121朝向于第二安装腔B123的一面。
在一实施例中,遮挡件B151’至少设有一个,第一轨段B1311、第二轨段B1312、第三轨段B1321或第四轨段B1322中的至少一者设有该遮挡件B151’。具体地,在本实施例中,上述各轨段均设有该遮挡件B151’。下面同样以位于第四轨段B1322上的遮挡件B151’为例,具体描述遮挡件B151’的结构以及设置位置。
参见图43至图47,该遮挡件B151’同上述第三方面的第一实施例中主遮挡件B151a的结构大致相同,其可以包括第一遮挡片B1511’和第二遮挡片B1512’;或者可以包括第一遮挡片B1511’、第一过渡片以及第二遮挡片B1512’。其中,第一遮挡片B1511’长度和第二遮挡片B1512’的长度可以分别与第四轨段B1322的长度保持大致相同,这样,可以对整个第四轨段B1322进行保护。当然,在其他实施例中,第一遮挡片B1511’的长度和第二遮挡片B1512’的长度可以小于第四轨段B1322的长度。
参见图44和图47,在本实施例中,该遮挡件B151’仅包括第一遮挡片B1511’和第二遮挡片B1512’。第一遮挡片B1511’和第二遮挡片B1512’均位于第四轨段B1322的第二通道B1323内,且第一遮挡片B1511’和第二遮挡片B1512’分别位于第二滑槽B1324沿第一方向F1的两侧。如图45和49所示,第一遮挡片B1511和第二遮挡片B1512同样均包括有相连的连接部B15111’和遮挡部B15112’,第一遮挡片B1511’的遮挡部B15112’以及第二遮挡片B1512’的遮挡部B15112’相对其对应的连接部B15111’向靠近第四轨段B1322的内部方向倾斜延伸,换句话说,遮挡部B15112’具有向第四轨段B1322的第二滑槽B1324内部(向远离第二安装腔B123的方向)延伸的趋势,即遮挡部B15112’可视为具有向斜上方延伸的趋势(见图45)。这样,可以确保第二滑动件B142得以顺畅地自交叉中心B133沿第四轨段B1322向远离交叉中心B133的一端进行滑移,避免了第一遮挡片B1511’和第二遮挡片B1512’与第二滑动件B142发生干涉。
在一实施例中,遮挡件B151’通过卡接、粘接或铆接等方式与顶盖B121固定。在本实施例中,如图45和图47所示,遮挡件B151’通过安装组件B152固定在顶盖B121上。其中,安装组件B152包括抵压件B1521,抵压件B1521的数量与遮挡件B151’的数量相同且相对应,抵压件B1521位于顶盖B121朝向第二安装腔B123的一侧,遮挡件B151’通过其对应的抵压件B1521固定在顶盖B121上。
在本实施例中,同样以位于第四轨段B1322处的遮挡件B151’以及抵压件B1521为例说明抵压件B1521的结构。具体地,抵压件B1521位于第四轨段B1322的第二通道B1323内并围绕第四轨段B1322的第二滑槽B1324设置,抵压件B1521能够将第一遮挡片B1511’的连接部B15111’以及第二遮挡片B1512’的连接部B15111’抵压固定至第二滑槽B1324沿第一方向F1的两侧。更具体地,抵压件B1521可以包括依次连接的第一抵压片B15211、第二过渡片B15212以及第二抵压片B15213,且第二过渡片B15212分别与第一抵压片B15211和第二抵压片B15213呈夹角设置。第一抵压片B15211用于将第一遮挡片B1511’的连接部B15111’抵压固定在第二滑槽B1324沿第一方向F1的一侧,第二抵压片B15213用于将第二遮挡片B1512’的连接部B15111’抵压固定在第二滑槽B1324沿第一方向F1的另一侧。当然,在其他实施例中,上述的第二过渡片B15212可以省略。需要说明的是,抵压件B1521的材料可以包括但不限于由硬质材料制成,例如金属材料。
参见图44、图45和图47,在一实施例中,安装组件B152还包括紧固件B1522(如螺钉或螺栓等),且紧固件B1522至少设有一个。具体地,顶盖B121上至少设有一个第一连接孔B1212,抵压件B1521上设有至少一个第二连接孔B15214。具体地,第二连接孔B15214可以设有至少三个,其中,第二过渡片B15212上设有至少一个第二连接孔B15214,第一抵压片B15211也可以设有至少一个第二连接孔B15214,第二抵压片B15213也可以设有至少一个第二连接孔B15214,在此不作具体限制。这样,可以提高遮挡件B151固定于第二定位组件B120的稳定性。紧固件B1522用于穿过第一连接孔B1212与第二连接孔B15214以将抵压件B1521与顶盖B121连接。通过紧固件B1522以及抵压件B1521相配合,可以将各遮挡件B151稳定地固定在对应的轨段的下方。
同样地,当第一滑动杆B1411位于第三轨段B1321或第四轨段B1322上的遮挡件B151’的滑移缝隙B1514’内时,在第一滑动杆B1411的挤压下,位于第三轨段B1321或第四轨段B1322上的遮挡件B151’发生弹性形变以处于变形状态,此时,第一遮挡片B1511’的遮挡部B15112’和第二遮挡片B1512’的遮挡部B15112’在第一滑动杆B1411的挤压下相互远离,遮挡件B151’不会与第一滑动杆B1411的移动发生干涉。当第一滑动杆B1411从位于第三轨段B1321或第四轨段B1322上的遮挡件B151’的滑移缝隙B1514’内移出后,遮挡件B151’复位以处于初始状态,此时,第一遮挡片B1511’的遮挡部B15112’与第二遮挡片B1512’的遮挡部B15112’相互靠近,第一遮挡片B1511’与第二遮挡片B1512’配合以覆盖第三轨段B1321或第四轨段B1322,避免异物从第二滑槽B1323的槽口落入第二安装腔B123内,影响定位组件B100正常使用。总而言之,可以理解为,当滑动件移入滑移缝隙B1514’时,遮挡件B151’会被挤压以处于变形状态。当滑动件移出滑移缝隙B1514’时,遮挡件B151’复位至初始状态以遮挡相应轨道。
根据前文描述可知,第三方面的第一实施例和第三方面的第二实施例中各遮挡件B151(即主遮挡件B151a和/或辅遮挡件B151b)可视为位于第一滑槽和第二滑槽B1324的上方,第三方面的第三实施例中各遮挡件B151’可视为位于第一滑槽和第二滑槽B1324的下方。当第三方面的第一实施例以及第三方面的第二实施例中的各遮挡件B151处于初始状态时,第三方面的第一实施例和第三方面的第二实施例中的各遮挡件B151均能够对第一轨道B131和第二轨道B132进行遮挡及防护。同样地,当第三方面的第三实施例中的遮挡件B151’处于初始状态时,第三方面的第三实施例中的各遮挡件B151’也能对第一轨道B131和第二轨道B132进行遮挡及防护。
需要说明的是,在不存在组合冲突的情况下,本申请第一方面、第二方面以及第三方面所涵盖的各个实施例中的特征能够相互进行组合。具体的组合方式可以根据实际使用场景和需求灵活确定,在此不作具体限制。
此外,还需要说明的是,本申请第一方面中的定位组件A100可以理解是底座。第一定位组件A110可以理解是底座中的转盘,第二定位组件A120可以理解是底座中的基座。同样地,本申请第二方面以及第三方面中定位组件B100可以理解是底座。第一定位组件B110可以理解是底座中的转盘,第二定位组件B120可以理解是底座中的基座。
以上实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上实施例仅表达了本申请的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对申请专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本申请构思的前提下,还可以做出若干变形和改进,这些都属于本申请的保护范围。因此,本申请专利的保护范围应以所附权利要求为准。
