具体实施方式
以下结合说明书附图及具体实施例对本发明做进一步描述：
在本发明的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”、“左右方向”、“高度方向”、“前后方向”等指示的方位或位置关系为基于附图1，儿童安全座椅内乘坐儿童时所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、仅具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，术语“第一”、“第二”、“第三”等仅用于描述目的，而不能理解为指示或暗示相对重要性。
需要说明的是，如无特殊说明，当某一特征被称为“固定”、“连接”在另一个特征，它可以直接固定、连接在另一个特征上，也可以间接地固定、连接在另一个特征上。除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
参见图1～19的儿童安全座椅，包括座椅本体100及通过沿上下方向倾斜延伸设置的转轴1转动连接在座椅本体100底部且用于与汽车座椅连接的连接器200，连接器200还可相对座椅本体100向前或向后伸出与汽车座椅连接，其中本发明中的“向前”是指儿童乘坐儿童安全座椅时所面向的方向，本发明中的“向后”是指儿童乘坐儿童安全座椅时所背向的方向，该安全座椅具有正向使用状态和反向使用状态，通过座椅本体100与连接器200之间的相对转动在正向使用状态和反向使用状态之间相切换安装，其中本发明中的正向使用状态下，乘坐在儿童安全座椅中的儿童所面向的方向与汽车正向行进方向相同，反向使用状态下，乘坐在儿童安全座椅的儿童所面向的方向与汽车正向行进方向相反，且当儿童安全座椅处于正向使用状态时，连接器200相对座椅本体100向后伸出与汽车座椅连接；当安全座椅处于反向使用状态时，连接器200相对座椅本体100向前伸出与汽车座椅连接，且为了更好地与汽车座椅连接，在正向使用状态下和反向使用状态下，连接器200都沿水平方向延伸。
座椅本体100的下表面具有当儿童安全座椅处于正向使用状态时沿水平方向延伸的第一支撑面M，且当儿童安全座椅处于正向使用状态时，儿童安全座椅为坐姿状态；座椅本体100的后表面具有当儿童安全座椅处于反向使用状态时沿水平方向延伸形成的第二支撑面N，且当儿童安全座椅处于反向使用状态时，儿童安全座椅为躺姿状态。本发明中的坐姿状态下，座椅本体1的后表面倚靠的平面与水平面之间的夹角α(参见图10)值比躺姿状态下，座椅本体1的后表面倚靠的平面(躺姿状态下该表面为虚拟平面)与水平面之间的夹角β(参见图17)值更大，坐姿状态下和躺姿状态下的座椅本体1的后表面倚靠的平面，是指座椅本体1的后表面上的同一位置的切面所在平面，而处于坐姿状态下，座椅本体1的后表面倚靠的平面则是汽车座椅的前表面所在的平面。
参见图17，第一支撑面M所在的平面和第二支撑面N所在的平面之间形成的夹角γ为锐角，该夹角γ的范围为5°～60°，在反向使用状态下，由于第二支撑面N处于水平面上，第一支撑面M所在的平面与水平面之间形成的夹角也为夹角γ，为 锐角，优选地，第一支撑面M所在的平面与水平面之间形成的夹角γ范围为25°～35°，与在正向使用状态下和反向使用状态下，第一支撑面M都沿水平方向延伸的设置相比，本实施例中儿童安全座椅设置有第一支撑面M与第二支撑面N是为了在反向使用状态下，乘坐的儿童斜躺角度更大，有更舒适的躺姿，相应地，为了配合反向使用状态下的躺姿，在正向使用状态下，转轴1由前向后向下倾斜延伸，在反向使用状态下，转轴1由前向后向上倾斜延伸，转轴1与连接器200固定连接，转轴1轴心线与连接器200上表面所在平面之间形成的夹角δ(参见图20)为钝角，优选地，夹角δ的范围为100-110°，进一步优选地，本实施例中转轴1轴心线与连接器200上表面的钝角夹角δ为105°。
在座椅本体100上且位于转轴1的后方设置有能够与连接器200相连或分离的第一连接件，座椅本体100上且位于转轴1的前方设置有能够与连接器200相连或分离的第二连接件，为了简化儿童安全座椅的结构，第一连接件和第二连接件分别为沿座椅本体100的左右方向延伸设置的第一连杆5和第二连杆6。
本例中，该座椅本体100的左右二侧对称设置有该连接器200，相应地该座椅本体100的左侧和右侧都分别设置有第一连杆5和第二连杆6。
参见图18-19，各侧连接器200包括连接器本体及固定设置在连接器本体上的第三连接件10，连接器本体包括通过转轴1与座椅本体100底部转动连接的连接架8及沿座椅本体100的前后方向滑动连接在连接架8上且用于与汽车座椅连接的接头9，接头9能够由连接架8的一端部伸出连接架8后与汽车座椅连接，且接头9伸出连接架8的长短可调，接头9上具有连接汽车座椅上ISOFIX接口的开口17，在开口17内还设置有用于与汽车座椅配合连接的活动锁钩部18，活动锁钩部18可相对开口17的上侧壁收拢或伸出，活动锁钩部18也具有开口，第三连接件10固定设置在连接架8上。本例中，为了在正向使用状态下使第三连接件10与座椅本体100能够顺畅连接，第三连接件10设置为在正向使用状态下，由前向后向下倾斜延伸。
二侧连接器200分别与第一连杆5或第二连杆6的两端相连或分离，且当二侧连接器200分别与第一连杆5的两端相连时，儿童安全座椅处于正向使用状态；当二侧连接器200分别与第二连杆6的两端相连时，儿童安全座椅处于反向使用状态；当二侧连接器200与第一连杆5、第二连杆6均分离时，二侧连接器200可相对座椅本体100转动。具体地，连接器200上设有能够与第一连杆5或第二连杆6配合插接或分离的通孔7，通孔7分别开设在第三连接件10上，当第一连杆5或第二连杆6插接在通孔7内，连接器200与第一连杆5或第二连杆6相连；当第一连杆5、第二连杆6均与通孔7分离，第一连杆5、第二连杆6均与连接器200分离，连接器200可相对座椅本体100转动。
在座椅本体100的底部对应第一连杆5两端部、第二连杆6两端部的位置分别设置有用于避让第三连接件10的第一避让槽13、第二避让槽14，当第一连杆5或第二连杆6与第三连接件10上的通孔7插接时，第三连接件10位于第一避让槽13或第二避让槽14内。
本例中，接头9与连接架8之间的连接关系采用现有的连接关系即可，不是重点，只需满足接头9能够由连接架8的一端部伸出连接架8且伸出长短可调及收纳于连接架8内即可。
该儿童安全座椅还包括用于将儿童安全座椅锁定在正向使用状态和反向使用状态时的锁定机构，锁定机构设置在座椅本体100和连接器200之间，且二侧连接器200和座椅本体100之间分别设置该锁定机构。
各侧锁定机构包括滑动设置在连接器200上的锁定件2及设置在座椅本体100底 部且位于转轴1前后二侧的且与锁定件2配合插接或分离的第一锁槽3和第二锁槽4，第一锁槽3位于第二锁槽4的后方，当锁定件2与第一锁槽3插接配合时，锁定机构将安全座椅锁定在正向使用状态；当锁定件2与第二锁槽4插接配合时，锁定机构将安全座椅锁定在反向使用状态；当锁定件2与第一锁槽3、第二锁槽4均分离时，锁定机构解锁。
锁定件2滑动设置在第三连接件10上，该锁定机构还包括设置在锁定件2和连接架8之间用于使锁定件2趋向于与第一锁槽3或第二锁槽4插接的弹性件11，弹性件11为弹簧，锁定件2上具有用于操作锁定件2使得锁定件2趋向于与第一锁槽3或第二锁槽4均分离的操作部2b，具体参见图20，锁定件2包括滑动设置在第三连接件10上的滑动部2a及固定设置在滑动部2a上的该操作部2b，具体地，滑动部2a滑动设置在第三连接件10的内部且滑动部2a的一端部穿出第三连接件10与第一锁槽3或第二锁槽4插接或分离，第三连接件10上对应操作部2b的位置沿滑动部2a的滑动方向开设滑槽12，操作部2a滑动穿设在滑槽12内。
参见图20，第一锁槽3开设在第一避让槽13的上槽壁上，第二锁槽4开设在第二避让槽14的上槽壁上，锁定件2的滑动部2a上对应第三连接件10的通孔7的位置开设通槽，当第一连杆5或第二连杆6插接在通孔7内时，第一连杆5或第二连杆6也插设在通槽内且与通槽能够相对滑动。
本例中，采用第三连接件10与座椅本体100相连或分离，且锁定件2和弹性件11分别设置在第三连接件10内，大大简化该安全座椅的结构。
参见图19，转轴1沿上下方向倾斜延伸设置，且转轴1的下端部固定连接在连接架8上，座椅本体100底部对应转轴1的位置开设插孔，转轴1插设在插孔内并在插孔内转动，转轴1的上端部还设有用于防止转轴1滑出插孔进而防止连接器200脱离座椅本体100的限位件16。在座椅本体100底部对应连接器200的连接架8位置开设用于避让连接架8转动的第三避让槽15，连接器200绕转轴1轴心线做180°转动。
连接架8自转轴1与连接架8的连接处分成连接架一段及连接架二段，连接架二段的长度长于连接架一段的长度，第三连接件10固定在连接架二段上，第三避让槽15用于避让连接架一段，且当安全座椅处于正向使用状态或反向使用状态时，连接架一段的上表面与第三避让槽15的上槽壁相抵接，以实现对连接器200的进一步支撑稳定，转轴1的轴心线与连接架二段上表面所在平面的夹角范围为100°-110°。
该儿童安全座椅的工作原理：
参见图1～10，儿童安全座椅处于正向使用状态，连接器200的连接架8沿水平方向延伸，座椅本体100的第一支撑面M沿水平方向延伸作为支撑，第三连接件10与第一连杆5相连，第一连杆5的端部插设在第三连接件10的通孔7内，第三连接件10位于第一避让槽13内，锁定件2插设在第一锁槽3内，锁定机构将安全座椅锁定在正向使用状态，此时，连接器200的接头9相对座椅本体100向后滑出连接架8通过活动锁钩部18与汽车座椅的ISOFIX接口连接，接头9上的开口17朝向儿童安全座椅的后方，且活动锁钩部18的开口朝下设置。
当需将儿童安全座椅反向使用时，连接器200与汽车座椅分离，然后操作锁定件2的操作部2b，使滑动部2a向下滑动压缩弹性件11进而使滑动部2a脱离第一锁槽3，如图7所示，锁定机构解锁，释放操作部2b，滑动部2a在弹性件11的作用下向上滑动复位。然后将连接器200的第三连接件10与第一连杆5分离，并将连接器200绕转轴1转动，参见图11～14，转动至第三连接件10将与第二连杆6相连，操作操作部2b使滑动部2a向下滑动并继续转动连接器200，待连接器200转动180°，释放操作部2b，滑动部2a在弹性件11的作用下插入第二锁槽4，锁定机构锁定，连接 器200相对座椅本体100固定。
然后将座椅本体100反向安装在汽车座椅上，使得座椅本体100的第二支撑面N沿水平方向延伸作为支撑，连接器200的连接架8沿水平方向延伸，并将连接器200的接头9滑出连接架8与汽车座椅的ISOFIX接口连接，参见图15～17，此时，连接器200的接头9相对座椅本体1向前滑出连接架8与汽车座椅的ISOFIX接口连接，接头9的开口17朝向儿童安全座椅的前方，且活动锁钩部18的开口仍然朝下设置。在安全座椅正向使用状态或反向使用状态时，接头9的开口17始终与汽车正向行进方向相反，且活动锁钩部18的开口始终朝下设置，方便与汽车座椅的ISOFIX接口进行配合。
该安全座椅，需要换向时，只需操作连接器200相对座椅本体100转动，然后进行正向或反向安装即可，操作方便，相比传统安全座椅，也大大简化了座椅本体100的结构，进而使得儿童安全座椅的结构更加简单，加工更加方便。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
