Description

儿童安全座椅支撑座
本申请是以CN申请号为201710616120.8，申请日为2017年7月26日的申请为基础，并主张其优先权，该CN申请的公开内容在此作为整体引入本申请中。
技术领域
本公开涉及儿童安全座椅领域，尤其涉及一种儿童安全座椅支撑座。
背景技术
儿童安全座椅是一种通过将儿童束缚在安全座椅内来有效提高儿童乘车安全的座椅。在汽车碰撞或突然减速的情况下，该座椅可以减少对儿童的冲击力和限制儿童的身体移动从而减轻对他们的伤害。在目前已有的儿童安全座椅中，基于欧洲强制标准的ISOFIX接口的儿童安全座椅被广泛应用。
考虑到车辆座椅平面与车内地板之间存在高度差，仅凭ISOFIX接口的连接难以承受来自于汽车碰撞或突然减速的惯性受力情况。因此，已有很多的儿童安全座椅为了支撑更加稳定在支撑座的前端设置了支撑腿，以便与车内地板形成可靠支撑，从而提高了儿童座椅的安全防护效果。
发明内容
发明人认识到对于使用者来说，由于背景技术中儿童安全座椅的安装涉及到多个位置，容易因使用者粗心或经验不足而发生部分安装未到位或忘记安装的情形。例如使用者在未将支撑腿调整到顶紧的使用位置时就进行ISOFIX接口的安装，或者使用者在良好安装的状态下解除支撑腿在使用位置的锁紧状态后又继续使用支撑座。此时虽然在车辆静止或匀速平稳运动时支撑座能够在车辆座位上保持稳定，但当车辆发生碰撞或急转等情况而导致车速较大幅度变化时，由于支撑腿未良好抵紧车内地面，容易造成支撑座大幅摆动或倾覆的问题，给乘坐儿童安全座椅的儿童带来严重伤害或惊吓。
有鉴于此，本公开实施例提供一种儿童安全座椅支撑座，能够尽量消除使用者安装时的安全隐患。
根据本公开的一个方面，提供一种儿童安全座椅支撑座，包括：底座、ISOFIX 机构和支撑腿，所述ISOFIX机构和所述支撑腿均设置在所述底座上，所述ISOFIX机构能够相对于所述底座伸缩以连接锚点，还包括：防误用关联机构，能够将所述ISOFIX机构的伸缩状态与所述支撑腿的支撑锁定状态进行关联，以使所述ISOFIX机构的伸缩状态只有处于收纳状态时所述支撑腿才能够在收合位置和稳定支撑位置之间切换，以及所述支撑腿只有处于支撑锁定状态时所述ISOFIX机构才能够在收纳位置和外伸连接位置之间切换。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本公开及其应用或使用的任何限制。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本公开的范围。同时，应当明白，为了便于描述，附图中所示出的各个部分的尺寸并不是按照实际的比例关系绘制的。对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为授权说明书的一部分。在这里示出和讨论的所有示例中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它示例可以具有不同的值。应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
如图1所示，为本公开儿童安全座椅支撑座的一实施例的分解结构示意图。结合图2-6，本实施例的儿童安全座椅支撑座包括：底座1、ISOFIX机构2和支撑腿3。底座1用于设置在车辆座椅内，且用于稳定支撑儿童安全座椅。ISOFIX机构2和所述支撑腿3均设置在底座1上，ISOFIX机构2能够相对于所述底座1伸缩以连接锚点。ISOFIX机构2可以从底座1中外伸与车辆的ISOFIX锚点进行连接，并能够收回到收纳位置。而支撑腿3能够相对于底座1旋转折叠，能够在收合位置和稳定支撑位置之间进行切换。
为了解决使用者安装误用的问题，本实施例还包括防误用关联机构。该机构能够将所述ISOFIX机构2的伸缩状态与所述支撑腿3的支撑锁定状态进行关联，以使所述ISOFIX机构2的伸缩状态只有处于收纳状态时所述支撑腿3才能够在收合位置和稳定支撑位置之间切换，以及所述支撑腿3只有处于支撑锁定状态时所述ISOFIX机构2才能够在收纳位置和外伸连接位置之间切换。防误用关联机构能够避免使用者在未将支撑腿调整到顶紧的使用位置时就进行ISOFIX接口的安装，使得使用者只有正常将支撑腿旋转到稳定支撑位置时才能够进行ISOFIX机构与ISOFIX锚点之间的连接，从而实现了儿童安全座椅支撑座的稳定安装，进而当车辆发生碰撞或急转等情况 而导致车速较大幅度变化时，能够避免支撑座因支撑腿未抵紧地面而大幅摆动或倾覆的问题。
为实现防误用关联机构的上述功能，该机构可以具体包括设置在底座1内部的第一驱动结构和第二驱动结构。其中，第一驱动结构能够在所述支撑腿3处于稳定支撑位置时解除对所述ISOFIX机构2的伸缩限制。第二驱动机构能够在所述ISOFIX机构2离开收纳位置时对所述支撑腿3进行锁定，以使所述支撑腿3在所述稳定支撑位置处于支撑锁定状态。
参考图1-4，第一驱动机构包括第一杠杆机构4。第一杠杆机构4的第一端43作用在所述ISOFIX机构2上，用于将所述ISOFIX机构2限制在收纳位置。所述第一杠杆机构4的第二端44能够与所述支撑腿3相互作用。所述支撑腿3到达稳定支撑位置时对所述第一杠杆机构4的第二端44施力，通过杠杆作用传递给所述第一杠杆机构4的第一端43，以使其解除对所述ISOFIX机构2的伸缩限制，从而使所述ISOFIX机构2能够从收纳位置向外伸出。参考图2，支撑腿3上靠近底座1一侧的第一端321上连接的驱动块31可以在支撑腿3旋转到稳定支撑位置时向下压动第一杠杆机构4的第二端44，而在支撑腿3旋转到稳定支撑位置之外的其他位置(参考图4)时，驱动块31离开第一杠杆机构4的第二端44。
第一杠杆机构4的转轴45可以设置在所述底座1内，并且在第一杠杆机构4上进一步设有第一复位机构41(例如图4中采用的拉簧，在其他实施例中也可以采用压簧或设置在转轴45和第一杠杆机构4之间的扭簧等)。该第一复位机构41能够在第一杠杆机构4的第二端44未受到支撑腿3的施力作用时，使所述第一杠杆机构4的第一端43始终作用在所述ISOFIX机构2上。第一杠杆机构4优选设置成相对于左右方向的中心线对称的两组杠杆结构，且两组杠杆结构通过连接杆42进行连接。
在本公开的另一实施例中，第一驱动机构也可以采用其他结构形式，例如利用钢丝绳或尼龙绳等柔性牵引件在支撑腿3处于稳定支撑位置时实现ISOFIX机构2的伸缩限制的解除操作，并为了实现特定的牵引方向而增加与柔性牵引件相配套的滑轮、弹簧等机构，这里就不再详细举例了。
ISOFIX机构2可以具体包括ISOFIX接头21和与所述ISOFIX接头21连接的伸缩杆22。所述伸缩杆22上远离所述ISOFIX接头21的端部能够在所述第一杠杆机构4的第一端43的阻挡作用下限制在收纳位置。限制方式并不限于第一杠杆机构4的第一端43的阻挡，也可以采用其他形式，例如磁性吸合或卡接等。ISOFIX接头21可 以与伸缩杆22直接连接，或者通过图1中的中间件25间接连接。
参考图2，伸缩杆22上远离所述ISOFIX接头21的端部设有开口向上的卡槽24，所述第一杠杆机构4的第一端43在杠杆作用下在上下方向上运动。当支撑腿3没有作用于第一杠杆机构4时，则第一复位机构41能够使第一杠杆机构4的第一端43向下卡入所述卡槽24内，以实现对所述伸缩杆22的伸缩限制。当支撑腿3作用于第一杠杆机构4时，通过杠杆作用使第一杠杆机构4的第一端43在向上时离开所述卡槽24，以解除对所述伸缩杆22的伸缩限制。此外，在另一个实施例中，ISOFIX机构2还可以包括伸缩杆定位片23，所述伸缩杆定位片23固定在所述底座1内，用于为所述伸缩杆22提供伸缩导向功能。
参考图3，支撑腿3包括支腿结构32和驱动件31。驱动件31与支腿结构32上安装所述底座1的一侧的第一端321连接。在支腿结构32的另一端可以设置支脚33。驱动件31能够在所述支腿结构32到达稳定支撑位置时对所述第一杠杆机构4的第二端44施力。驱动件31的外轮廓可以与第一杠杆机构4的第二端44相配合，并能够随支腿结构32共同转动。而当驱动件31在对所述第一杠杆机构4的第二端44施力的状态下，第二驱动结构可以在所述ISOFIX机构2离开收纳位置时对所述驱动件31进行锁定。支撑腿3可以在收合状态和支撑锁定状态之间切换，当其处于支撑锁定状态下，支撑腿3与所述底座1之间的内夹角优选为75度，以符合相关安全标准。
参考图4，第二驱动机构具体包括第二杠杆机构5和设置在所述第二杠杆机构5上的第二复位机构51。第二杠杆机构5的转轴54可以设置在所述底座1内，且第二杠杆机构5能够绕该转轴54转动。所述第二杠杆机构5的第一端53能够作用于所述支撑腿3，能够使所述支撑腿3在稳定支撑位置下处于支撑锁定状态。第二杠杆机构5的第二端52与处于收纳位置的所述ISOFIX机构2相抵靠，并能够在所述ISOFIX机构2离开收纳位置时与所述ISOFIX机构2脱离接触状态。第二复位机构51的复位力通过杠杆作用传递给所述第二杠杆机构5的第一端53，以使所述第二杠杆机构5的第一端53对所述支撑腿3进行锁定。
支撑腿3上的驱动件31能够在所述支腿结构32到达稳定支撑位置时对所述第一驱动机构施力，以解除所述第一驱动机构对所述ISOFIX机构2的伸缩限制。此时当使用者向外拉出ISOFIX机构2中的伸缩杆22，使其离开收纳位置时，第二杠杆机构5的第一端53则可以对所述驱动件31进行锁定。参考图2，在驱动件31上可设置阻挡用的凹槽或其他阻挡结构，而第二杠杆机构5的第一端53可以插入驱动件31上的 凹槽或阻挡结构来实现锁定作用，而锁定了驱动件即使得支撑腿3不能旋转，从而避免ISOFIX连接在非拆卸状态时支撑腿脱离稳定支撑位置，从而造成安全风险。
当伸缩杆22上远离所述ISOFIX接头21的端部处于收纳位置时，该端部能够在收纳位置抵靠第二杠杆机构5的第二端52，在抵靠作用下，第二杠杆机构5能够克服所述第二复位机构51的施力作用而维持对所述支撑腿3的非锁定状态，此时可以正常地旋转支撑腿，以实现支撑座的拆卸。
前面提到驱动件31能够在所述支腿结构32到达稳定支撑位置时对所述第一驱动机构施力，以解除所述第一驱动机构对所述ISOFIX机构2的伸缩限制，此时第二杠杆机构5的第一端53就可以在伸缩杆22离开收纳位置时对所述驱动件31进行锁定，确保支撑腿不会脱离稳定支撑位置。
在本公开的另一实施例中，第二驱动机构也可以采用其他结构形式，例如利用钢丝绳或尼龙绳等柔性牵引件在ISOFIX机构2离开收纳位置时实现支撑腿3的锁定操作，以使支撑腿3在稳定支撑位置处于支撑锁定状态，并为了实现特定的牵引方向而增加与柔性牵引件相配套的滑轮、弹簧等机构，这里就不再详细举例了。
参考图3和图6，在所述驱动件31与所述支腿结构32的第一端321之间可设置旋转控制杆36和挡块6。所述旋转控制杆36的两端分别与所述驱动件31和所述支腿结构32的第一端321连接，且所述挡块6对部分所述旋转控制杆36和所述驱动件31进行支撑。通过旋转控制杆36能够使驱动件31与支腿结构32之间维持相对固定关系，驱动件31能够随支腿结构32转动，而限制了驱动件31的转动则也限制了支腿结构32的转动。挡块6的外轮廓可根据驱动件31和旋转控制杆36的外轮廓设计，以维持底座1与支撑腿3之间的连接和支撑关系。
参考图5，在所述底座1的下表面可以设有收合槽11，所述支撑腿3能够旋转进入所述底座1的收合槽11，以减小收合后的占用空间，并使得底部轮廓更平，便于放置。而支撑腿3上用于支撑地面的第二端322上可相应地设置收合锁定机构，通过收合锁定机构能够在所述支撑腿3的收合位置锁定和解锁。图5示出了一种收合锁定机构的具体结构形式，其包括安装在所述支撑腿3的第二端322的凹形件34，所述凹形件34能够与所述收合槽11上对应于所述支撑腿3的第二端322的突出结构12配合进行卡接，在所述凹形件34与所述支撑腿3之间还设有第三复位机构37。第三复位机构37能够向外推出凹形件34，以使凹形件34与突出结构12维持卡紧状态，以避免支撑腿3自然掉落。当使用者希望将支腿结构32从收合槽11中取出时，可以通过 操作支脚33上的解锁开关35来克服第三复位机构37的作用力，以使凹形件34离开突出结构12的卡接位置。在其他实施例中，支撑腿3也可以直接旋转到底座1的下表面，并呈向下凸起的形式，其也可采用其他形式的收合锁定机构避免支撑腿3自然掉落。
下面结合图1-6所示的儿童安全座椅支撑座实施例，对具体使用过程及防误用的原理进行详细地说明。
在使用者准备将本公开儿童安全座椅支撑座安装到车辆的座椅上之前，儿童安全座椅支撑座的状态如图4和图5所示。此时，支撑腿3的支腿结构32收合在底座1下表面的收合槽11中，并通过收合锁定机构维持其不自然掉落。而ISOFIX机构2也处于收纳位置，驱动块31没有作用于第一杠杆机构4的第二端44，因此在第一复位机构41的作用下，第一杠杆机构4的第一端43阻挡在ISOFIX机构2的伸缩杆22的端部，使其不能拔出。
当使用者准备进行支撑座的安装时，使用者只能先操作支撑腿3，使支撑腿3相对于底座1从收合位置向下旋转，从而到达稳定支撑位置。而ISOFIX机构2此时处于受限状态无法被拔出。只有当支撑腿3到达了稳定支撑位置时，驱动块31才能够对第一杠杆机构4的第二端44施力以克服第一复位机构41的作用，通过杠杆作用使第一杠杆机构4的第一端43离开针对于伸缩杆22的端部的阻挡位置。
如图2所示，此时使用者才能够向外拉出伸缩杆22，以便进行ISOFIX接头21与车辆上的ISOFIX锚点的连接。而拉出伸缩杆22时，伸缩杆22的端部也同时的离开了对第二杠杆机构5的第二端52的阻挡限制位置，则第二杠杆机构5在第二复位机构51的作用下使第一端53插入到驱动块31上的凹槽中，对驱动块31的运动形成限制，进而对支撑腿31的稳定支撑状态实现锁定。换句话说，只要伸缩杆22离开收纳位置，无论向外伸出多长，支撑腿31都会被锁定在稳定支撑位置，以避免使用者安装时没有注意到支撑腿31是否正确安装。
当使用者希望将儿童安全座椅支撑座从车辆座椅上拆卸下来时，需要先解除ISOFIX接头21与ISOFIX锚点之间的连接，并使伸缩杆22向内缩回到收纳位置。只有到达收纳位置时，伸缩杆22的端部才可以作用于第二杠杆机构5的第二端52，以使第二杠杆机构5克服第二复位机构51的作用，而通过杠杆作用能够将第一端51从驱动块31的凹槽中拔出，解除对驱动块31的限制。使用者这时才能够进行支撑腿3的旋转回收。换句话说，只有将伸缩杆22收回到收纳位置，才允许支撑腿3离开稳 定支撑位置。
通过前述本公开儿童安全座椅支撑座各个实施例的结构实现可以理解，使用者在这种结构的限制下无论是进行安装还是拆卸都必须遵循特定的顺序，而这种顺序杜绝了支撑腿在支撑座被安装的状态下处于非稳定支撑状态的机会，消除了使用者因不熟练或粗心时而错误地将支撑腿安装成未顶紧的状态的可能性，进而确保支撑腿在支撑座被安装的状态下始终顶紧车内地面，即便车辆发生碰撞或急转等情况而导致车速较大幅度变化，也可以有效通过抵紧车内地面而避免支撑座大幅摆动或倾覆，从而保护乘坐儿童安全座椅的儿童，避免其受到严重伤害或惊吓。
最后应当说明的是：以上实施例仅用以说明本公开的技术方案而非对其限制；尽管参照较佳实施例对本公开进行了详细的说明，所属领域的普通技术人员应当理解：依然可以对本公开的具体实施方式进行修改或者对部分技术特征进行等同替换；而不脱离本公开技术方案的精神，其均应涵盖在本公开请求保护的技术方案范围当中。
