如图1-3所示，本发明提供一种座椅调节机构，包括滑轨组件1和操作杆2，滑轨组件1包括上轨11和下轨12，下轨12固定于车辆的底板，且下轨12设置有若干沿轴向间隔的第一锁孔122a，上轨11与座椅本体相连，上轨11通过滑动件13支撑于下轨12，并能够通过该滑动件13沿下轨12进行滑动，以改变座椅本体在车体内的位置。
该滑轨组件1还包括锁定件14、第一弹性件15和解锁件16。上轨11设有第一安装孔111，锁定件14安装于第一安装孔111，并能够沿第一安装孔111进行上下位移，锁定件14的上端部能够伸出第一安装孔111，锁定件14的下端部设有与第一锁孔122a相匹配的第一锁齿141a，第一弹性件15设于上轨11内，并与锁定件14相抵接，以在常态下推抵锁定件14的第一锁齿141a卡入相应第一锁孔122a，进而限制上轨11相对下轨12的轴向滑动，此时，座椅本体处于锁定状态，座椅本体在车体内的位置确定。解锁件16包括解锁片161，该解锁片161中部铰接，操作杆2与解锁片161相连，并能够驱使解锁片161绕铰接点转动，转动的解锁片161能够与锁定件14的上端部相撞，以迫使锁定件14沿第一安装孔111向下位移，并使得第一锁齿141a与相应第一锁孔122a相脱离，进而解除上轨11、下轨12的锁定状态，此时，可通过操作杆2来带动上轨11(也即座椅本体)相对下轨12在车体内部进行纵向位置的调整。
在具体的方案中，参见图4-9，锁定件14可以包括锁卡141，锁卡141可以为板状，其截面可以呈L形，该L形是指大致为L形，其包括呈一定夹角相连的第一板和第二板，第一板可以自下而上插接于第一安装孔111，这种插接配合使得第一板只能够相对上轨11进行上下位移，而不能够进行纵向的相对位移，也就是说，锁定件14与上轨11在纵向上可以保持同步 位移，以保证锁定件14与下轨12在轴向相抵接时，即可以对上轨11的轴向位置进行锁定；第二板可以设有沿横向延伸、并沿轴向间隔的第一锁齿141a和第二锁齿141b。上轨11可以设有沿轴向间隔的过孔112和与第二锁齿141b相匹配的第二锁孔113。在锁定状态下，第一锁齿141a能够穿过过孔112、并与第一锁孔122a沿轴向卡接，第二锁齿141b能够沿轴向卡接于第二锁孔113。
采用这种结构，一方面，第二锁齿141b与第二锁孔113的轴向卡接配合，可以定位锁卡141下端部与上轨11的轴向相对位置，配合锁卡141上端部与第一安装孔111的插接配合，可将锁卡141的上下两端部均沿轴向固定于上轨11，更有利于保证锁卡141与上轨11轴向位移的同步性；另一方面，锁卡141的两个锁齿同时与上轨11、下轨12进行轴向的卡接配合，可以更大程度地保证上轨11与下轨12的可靠锁定。
锁定件14在锁定状态(即常态)与解锁状态之间切换时，锁定件14可以进行上下位移，在这一过程中，第一锁齿141a可以始终位于过孔112中，第二锁齿141b可以始终位于第二锁孔113内。也就是说，设置于上轨11的过孔112、第二锁孔113还具有导向作用，以导引锁卡141的移动方向，可以较大程度地保证解锁后与第一锁孔122a相脱离的第一锁齿141a在需要重新进入锁定状态时，能够准确地卡入第一锁孔122a，以避免出现解锁后锁卡141的下端部沿纵向摆动，而导致第一锁齿141a与第一锁孔122a在轴向上错位、不能够准确卡入的情形。
需要指出，本发明实施例并不限定上述第一锁齿141a、第二锁齿141b的数量，在具体实施时，本领域技术人员可以根据实际需要进行设置。在优选的方案中，如图8、图9所示，上述第一锁齿141a、第二锁齿141b均可以仅设置一个，以降低第一锁齿141a、第二锁齿141b的加工以及配合精度要求；可以理解，第一锁齿141a的数量为多个时，各第一锁齿141a的轴向间距必须足够精确，才能够保证各第一锁齿141a均卡入相应的第一锁孔122a，这对于锁卡141的加工精度以及第一锁齿141a与第一锁孔122a的配合精度就提出较高的要求，当然，这种方案本发明实施例并不排除，其同样属于本发明所要求保护的方案。
基于第一锁齿141a以及第二锁齿141b都仅为一个的情形，为保证锁 卡141的上下位移方向，还可以在上轨11上设置专门的导向孔114，锁卡141的第二板还可以设置对应的导向齿141c。在锁定件14上移锁定或下移解锁的过程中，导向齿141c可以始终位于导向孔114内，以对锁卡141的位移进行导向。同样地，上述导向齿141c、导向孔114的数量也不做限定，但需要注意的是，导向孔114和导向齿141c的数量应当相同，并保持一一对应的配合关系。
进一步地，还可以对第一锁齿141a、第二锁齿141b、导向齿141c的外形以及上述三种齿与相应孔的配合关系进行描述。
具体而言，第一锁齿141a、第二锁齿141b中可以至少有一者为T形齿，该T形齿可以包括立部和平部；可以理解，立部和平部的定义并不表示锁齿相应部分在实际应用中的状态，其仅是为了便于描述锁齿的结构而将锁齿放置为T形时对锁齿两部分的区分命名。在本文中，“内”、“外”等方位词的描述，均是相对于滑轨组件1的纵轴线的而定义，参照图12，对于任一部件而言，其靠近滑轨组件1纵轴线的一端(端面)可称之为内端(内端面)，远离滑轨组件1纵轴线的一端(端面)可称之为外端(外端面)。
若第一锁齿141a为T形齿，在一种方案中，第一锁齿141a的立部能够穿过过孔112、第一锁孔122a，其平部可以直接与第一锁孔122a的外端面沿横向相抵，也可以与第一锁孔122a的外端面沿横向呈小间隙配合，以在第一锁齿141a沿横向产生位移时再与第一锁孔122a的外端面相抵接，进而避免锁定状态下第一锁齿141a沿横向自第一锁孔122a脱出；在另一种方案中，如图12所示，第一锁齿141a的平部可以卡入第一锁孔122a，以在纵向锁死锁卡141、下轨12，且该平部可以直接与上轨11的外壁面沿横向相抵，也可以与上轨11外壁面呈小间隙配合，以在第一锁齿141a沿横向产生位移时再与上轨11的外壁面沿横向相抵，进而避免锁定状态下第一锁齿141a沿横向自第一锁孔122a脱出。
若第二锁齿141b为T形齿，第二锁齿141b的立部能够卡入第二锁孔113，以在纵向锁死锁卡141和上轨11，第二锁齿141b的平部也可以直接或在第二锁齿141b受驱沿横向位移时与上轨11的外壁面相抵，进而避免锁定状态下第二锁齿141b沿横向自第二锁孔113内脱出。
可以理解，上述第一锁齿141a、第二锁齿141b均是抵接于不同的锁孔，使得各锁齿与下轨12之间可以形成多道横向抵接结构，可更大程度地保证锁卡141与下轨12的可靠连接。
结合前述的内容，第一锁齿141a与第一锁孔122a相匹配，该匹配是指第一锁齿141a插入第一锁孔122a的部分(如为T形齿，该部分可以为T形齿的立部，也可以为平部)的纵向尺寸与第一锁孔122a相同，以保证第一锁齿141a卡入第一锁孔122a后，二者在纵向上无间隙，在实际中，第一锁孔122a、第二锁孔113(如图6)均可以为下部尺寸大、上部尺寸小的楔形，以在锁卡141上移时相应锁齿能够与相应锁孔沿垂向楔死；而第一锁齿141a与过孔112之间则无需采用上述的紧密配合结构，以降低加工的精度要求，也就是说，过孔112的纵向尺寸可以大于第一锁齿141a插入过孔112内的部分(T形齿的立部)的纵向尺寸。同样地，第二锁齿141b也要求与第二锁孔113相匹配，该匹配是指第二锁齿141b插入第二锁孔113的部分(如为T形齿，该部分为T形齿的立部)的纵向尺寸与第二锁孔113相同，以使得第二锁齿141b在卡入第二锁孔113后，二者之间在纵向上无间隙；而第二锁齿141b与第一锁孔122a之间也无需采用紧密配合结构，即第二锁齿141b插入第一锁孔122a内的部分(T形齿的平部)的纵向尺寸可以小于第一锁孔122a。
如此，即可得出一种实施方式(附图12所显示实施方式)中第一锁齿141a、第二锁齿141b、第一锁孔122a、第二锁孔113以及过孔112等部件的纵向尺寸的大小关系：第一锁齿141a平部＝第一锁孔122a>过孔112>第一锁齿141a立部、第一锁孔122a>第二锁齿141b平部>第二锁齿141b立部＝第二锁孔113。采用这种大小关系进行设置，对于第一锁齿141a、第二锁齿141b而言，都只有一个孔与之在纵向上紧密配合，可以大幅降低加工以及配合精度要求，进而可降低制造难度、制造成本。
需要说明，上述关于第一锁齿141a的立部、第二锁齿141b的立部、过孔112、第一锁孔122a以及第二锁孔113等部件纵向尺寸的大小关系的描述，仅为本发明实施例的一种示例性描述，其并不能够作为对本发明所提供座椅调节机构的实施范围的限定，在具体实施时，本领域技术人员也可以采用其他的大小关系；例如，第一锁齿141a立部、第二锁齿141b立 部、过孔112、第一锁孔122a以及第二锁孔113的纵向尺寸可以均相同，在锁定状态下，第一锁齿141a可以同时与过孔112、第一锁孔122a沿轴向卡紧，第二锁齿141b可以同时与第一锁孔122a、第二锁孔113沿轴向卡紧，以提高抵接强度，更有利于保证上轨11、下轨12在轴向上的可靠定位。
至于导向齿141c，由于其只需要提供导向作用，因此，其可以采用简单的直齿形式，以方便加工，当然，其也可以设置为T形或者其他各种形状。导向齿141c、导向孔114的纵向尺寸与前述的第一锁齿141a、第二锁齿141b等无直接联系，只要保证导向齿141c与导向孔114之间可以进行配合即可，具体来说，可将导向孔114的纵向尺寸设置为略大于或者等于导向齿141c；另外，如果导向齿141c也插接于第一锁孔122a，如图12所示，导向齿141c的纵向尺寸可以略小于第一锁孔122a。
锁卡141还可以设有标示结构，以表征第一锁齿141a和/或第二锁齿141b的相对位置，进而可以辅助工作人员确定锁定件14的安装方向。
详细而言，如图8、图9所示，该标示结构可以为设于锁卡141上端部的倒角141g和圆角141h，倒角141g和圆角141h中，一者可以与第一锁齿141a位于纵向同侧，另一者可以与第二锁齿141b位于纵向同侧，以方便工作人员确定第一锁齿141a、第二锁齿141b的位置，进而确定该锁卡141相对上轨11的安装方向。上述标示结构也可以仅为倒角141g、圆角141h中的一者，即仅采用其中一者与第一锁齿141a或第二锁齿141b的位置相对应，同样能够方便工作人员明确该锁卡141的安装方向。
可以理解，标示结构并不局限于上述的倒角141g和圆角141h的形式，也可以为设置为其他结构，例如，可以在锁卡141上设置三角形、矩形、梯形等形状的标示孔，通过该标示孔同样能够确定锁卡141相对上轨11的安装方向。
请再次参考图3，上轨11的下端面可以设有开口向下且沿轴向延伸的第一凹槽115，第一凹槽115两侧壁的下端均可以设有向上翻折的外卷边117，上述第一安装孔111可以设于第一凹槽115的侧壁与顶壁的连接处，前述的过孔112、第二锁孔113以及导向孔114均可以设置于第一凹槽115的侧壁的下端部，并沿横向贯穿该侧壁。
安装时，如图4、图5所示，锁卡141的第一板的一个板面可以与第一凹槽115的侧壁相贴合，另一板面可以设有阻挡结构，第一弹性件15可以为弹力绳，弹力绳的两端固定，具体可以固定在设置于第一凹槽115侧壁的第二安装孔116中，弹力绳的中部可以挂接于阻挡结构，并对锁定件14产生推抵力；该推抵力可以朝上，并朝向锁卡141所贴合的第一凹槽115的侧壁，以使得锁卡141的第一锁齿141a能够卡入相应第一锁孔122a，且第一板可以与第一凹槽115的侧壁相贴紧，再配合前述的第一锁齿141a、第二锁齿141b所采用的T形齿结构，可以对锁卡141的横向位置进行确定。除弹力绳的形式外，上述的第一弹性件15也可以采用常规的弹簧等形式的弹性元件，其一端可以固定，另一端可以与阻挡结构相抵，同样能够实现上述效果。
在第一种实施方式中，第一板可以开设有沿横向贯穿的通孔141d，通孔141d的孔壁可以具有翻边141e，该翻边141e即可以为前述的阻挡结构。如图9所示，该翻边141e可以位于通孔141d的上部孔壁，当然，其也可以位于通孔141d的下部孔壁或者侧部孔壁，而无论设于何种位置，都要保证安装完成后，翻边141e的安装高度低于第二安装孔116，使得第一弹性件15挂接于该翻边141e后，能够对锁卡141产生如上的推抵力。
在第二种实施方式中，阻挡结构可以为设于第一板的另一板面的挡块等形式的阻挡件，安装完成后，该阻挡件的安装高度同样要低于第二安装孔116。
比较而言，第一种实施方式中翻边141e的设计利用了第一板本身的材料，结构更为简单，加上该通孔141d的设置，有利于降低锁卡141的重量，而第二种实施方式的加工过程则较为简单，直接在第一板上焊接挡块即可；当然，这两种实施方式均可以实现与第一弹性件15相配合、进而对锁卡141产生如上推抵力的技术效果，在实施时，本领域技术人员可以根据实际需要进行选择。
上述锁定件14的数量可以为两个，第一凹槽115两侧壁与顶壁的连接处均可以设有前述的第一安装孔111，两锁定件14可以一一对应地插接于两第一安装孔111内，并与第一凹槽115相应的侧壁相贴合。下轨12的上端面可以设有开口向上且沿轴向延伸的第二凹槽121，第二凹槽121的两 侧壁远离其底壁的一端均可以具有向下翻折的内卷边122，两内卷边122均可以沿轴向间隔设有前述的第一锁孔122a，两锁定件14的第一锁齿141a可以一一对应地与两内卷边122的相应第一锁孔122a相配合。
采用两个锁定件14的方案，相比于仅有一个锁定件14的情形，可为上轨11、下轨12之间提供更大的轴向抵紧力，以更大程度地保证上轨11在轴向上的锁定效果。
进一步地，还可以包括防脱限位件17，防脱限位件17固定于第一凹槽115的侧壁，防脱限位件17与第一板可以间隙配合，也可以直接相抵，在本发明实施例中，优选采用间隙配合的方案，以避免防脱限位件17的设置影响锁卡141的上下位移。如图11所示，在锁卡141可能发生横向位移时，防脱限位件17配合第一凹槽115的侧壁以及第一弹性件15，可以更好地限定第一板(即锁卡141)的横向相对位置。
具体而言，可参考图10，并结合图5、图11，防脱限位件17可以整体为框形，以降低其重量，防脱限位件17横向的侧部可以具有阶梯面，该阶梯面包括沿横向逐级远离防脱限位件17纵轴线的第一侧面171、第二侧面172和第三侧面173。“逐级远离”是指三者远离防脱限位件17纵轴线的程度不同，第一侧面171最靠近防脱限位件17的纵轴线，第二侧面172相对第一侧面171远离防脱限位件17的纵轴线，第三侧面173相对第二侧面172远离防脱限位件17的纵轴线。
在安装时，可将第三侧面173焊接于第一凹槽115的侧壁(以下称之为焊接侧壁)，第二侧面172可以与焊接侧壁相平行，且第二侧面172与焊接侧壁在横向的间隙可以大致与第一板的厚度相当(或者略大于第一板的厚度)，以通过第二侧面172对第一板进行抵接限位(使第二侧面172与第一板呈前述的间隙配合)，第一侧面171相对第二侧面172更靠近防脱限位件17的纵轴线，可用于避让该阻挡结构。
整体而言，该防脱限位件17的同一侧部可以包括对称的两个阶梯面，两阶梯面的第一侧面171可以相接(实际上形成了一个第一侧面171)，两第二侧面172位于相接的第一侧面171相对的两端，两第三侧面173又位于两第二侧面172相对的两端，在实施时，该侧部可通过两第三侧面173与第一凹槽115的侧壁相连，两第二侧面172与锁卡141相抵或者间隙配 合。
该防脱限位件17的横向两侧部中，可以仅在其中的一者设置上述的阶梯面，也可以为两者均设置上述的阶梯面，具体与锁定件14的数量有关。如果锁定件14的数量为两个，则可在防脱限位件17的横向两侧部均设置阶梯面，以同时对两个锁定件14进行抵接限位。
需要说明，上述框形的、具有阶梯面的防脱限位件17仅是本发明实施例的一种优选方案，其并不能够作为对本发明所提供座椅调节机构的实施范围的限定，在满足使用功能的前提下，该防脱限位件17也可以采用其他结构；例如，该防脱限位件17可以为实心的板状结构，并在其侧部设置阶梯面。
下轨12可以沿轴向间隔设有两限位块123，具体是设置在第二凹槽121的底壁上，前述的防脱限位件17可以与一个限位块123相抵，以限定上轨11相对下轨12沿轴向的极限滑动位置。
详细而言，为便于描述，可将两限位块123中靠近车头的一者称之为前限位、远离车头的一者称之为后限位，当防脱限位件17与前限位相抵时，可限定上轨11(座椅本体)的前移极限位置，而当防脱限位件17与后限位相抵时，又可限定上轨11(座椅本体)的后移极限位置。进一步地，还可以在防脱限位件17的轴向两端设置消音层(垫)，该消音层具体可以采用橡胶等软质材料制备，以降低防脱限位件17与限位块123撞击时所产生的噪音。
采用上述结构，防脱限位件17可以同时具备与锁卡141相抵紧的防脱功能、与限位块123相抵的限位功能以及消音功能，将三个功能集成于同一个部件，可减少部件的使用数量，以简化本发明所提供座椅调节机构的结构，且有利于降低重量。
除此之外，也可以在上轨11上单独设置限位凸块等形式的限位件，以通过该限位件与下轨12的限位块123相抵接，同样能够限定上轨11相对下轨12的极限滑动位置；或者，也可以通过锁卡141与限位块123的抵接，来对上轨11进行限位。
如图7所示，并结合图5，锁定件14还可以包括消音帽142，锁卡141的上端部伸出第一安装孔111的部分与消音帽142相连。该消音帽142具 体可以采用橡胶、塑料等材料制备，在解锁时，转动的解锁片161可以与消音帽142相撞击，这一过程中，由于消音帽142的存在，可以大幅降低解锁片161与锁定件14撞击所产生的噪音；同时，锁定件14在被迫向下位移时，消音帽142的下端面又能够与上轨11相撞击，以限制锁定件14的下移距离。
而且，在消音帽142的下端面与上轨11相撞击时，锁定件14的下端面可以悬空，即处于解锁状态下的锁定件14的下端部没有与任何部件相撞，可以排除解锁时锁定件14下端发出噪音的可能性。
如图8所示，锁卡141的上端部设有自上边沿向下延伸的缩口141f，该缩口141f具体可以为槽口尺寸小、槽内尺寸大的缩口槽，例如，该缩口141f的截面可以为大于1/2圆的圆形、椭圆形或者腰圆形等。缩口141f的数量可以为一个，也可以为多个，具体可结合实际情况而定。
消音帽142的下端面可以设有卡槽142a，锁卡141可以插入卡槽142a，并通过缩口141f与消音帽142卡装；消音帽142的侧面可以设有一个或者多个与卡槽142a相连通的观察孔142b，用于观察锁卡141与消音帽142的安装状态，以确定消音帽142是否安装到位。
如上所述，锁定件14的下移距离可以通过消音帽142来限定，而其上移距离则可以通过第一锁齿141a、第二锁齿141b、导向齿141c与相应孔在上下方向的抵接进行限定。
针对上述各实施方式所涉及的座椅调节机构，以下本发明实施例还将对解锁件16的具体结构进行描述。
如图3、图4所示，解锁件16还可以包括呈U形的固定片162，固定片162的两侧板可以具有向外翻折的翼板，固定片162可以通过两翼板与上轨11相连，并罩设于锁定件14的上方，以对锁定件14进行防护，可较大程度地避免灰尘等杂质落入，而影响锁定件14动作的灵活性和可靠性。
解锁片161的安装结构与固定片162有关，图3实施例中，固定片162一个翼板的横向侧边具有向下翻折的侧护板，解锁片161的中部可以通过铆钉165与该侧护板相连，且该铆钉165为台阶铆钉，可实现解锁片161与固定片162的相对转动，也就是说，解锁片161可以铰接于固定片162。如此，可以先对解锁件16进行组装，然后再将解锁件16整体安装于上轨 11，如图2所示，安装完成后，侧护板、解锁片161与侧护板的铰接处都位于下轨12的外侧，可避免解锁片161的安装而对上轨11与下轨12相对滑动所造成的干涉。
除上述的方式外，解锁片161的中部也可以直接铰接于上轨11，此时，解锁片161与固定片162之间无直接的连接结构。
请继续参考图2，并结合图4，组装完成后，解锁片161的第一端可以与操作杆2相连，第二端可以位于固定片162与上轨11之间，通过驱动操作杆2，可以带动解锁片161进行转动。固定片162的底壁可以设有消音垫163，该消音垫163具体可以为橡胶材质，当解锁片161回复至常态时，其第二端可以与消音垫163相撞击，以避免重新恢复至锁定状态时解锁片161与固定片162相撞击所产生的噪音。
进一步地，还可以设置第二弹性件，第二弹性件的一端固定，另一端可以与解锁片161相抵，当作用于操作杆2的外力消失时，第二弹性件能够推动解锁片161回复至常态。
具体而言，该第二弹性件可以为扭簧164，如图2所示，该扭簧164可以套接于铆钉165，其两个伸出端中，一者可以与解锁片161相抵，另一者可以与固定片162相抵，且扭簧164的两个伸出端均可以设置弯头，以在与解锁片161、固定片162抵接时保证连接的可靠性。解锁时，操作杆2可以驱使解锁片161进行转动，进而驱使锁定件14向下位移，这一过程中，扭簧164可以积聚弹性力；当作用于操作杆2的外力消失，扭簧164的弹性力可以释放，以驱使解锁片161回复至原始位置。
参照图11，并结合图3，在安装时，可以先组装上轨11，具体而言，可以先将锁定件14、弹性件15安装到位，然后再安装防脱限位件17；在上轨11组装完成之后，可将上轨11通过滑动件13沿轴向过盈插装于下轨12中；解锁件16可以预先安装于上轨11，也可以等上轨11与下轨12对接完成后，再与上轨11进行安装。
上述滑轨组件1的数量可以为两个，且两滑轨组件1可以沿横向间隔设置，以保证调节座椅本体沿纵向位移过程中的稳定性。操作杆2可以呈U形，该U形的两个侧杆可以一一对应地与两滑轨组件1的解锁片161相连，以便通过该操作杆2同时对两个滑轨组件1进行操作。
综合上述内容，本发明所提供座椅调节机构的有益效果为：所使用部件较少，整体结构较为简单，重量较轻，有利于整车减重；尤其是锁定件14，其设计小巧，重量轻，单个锁定件14的质量仅为10g左右，相比于现有技术中20g左右的锁定件，重量获得大幅降低；消音帽142、消音垫163以及消音层等多种形式的消音设置，可大幅降低解锁或锁定过程中所产生的噪音；防脱限位件17的设置，将防脱、限位、消音等多种功能集成于一体，可大幅简化锁定件14的定位机构以及上下轨的限位结构。
本发明还提供一种座椅总成，包括座椅本体，该座椅本体通过调节机构安装于车辆的底板，以实现座椅本体在纵向上的位置调整，该调节机构即为上述各实施方式所涉及的座椅调节机构。
由于上述的座椅调节机构已经具备如上的技术效果，那么，具有该座椅调节结构的座椅总成亦当具备相类似的技术效果，故在此不做赘述。
以上仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
