具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
不失一般性，本实施方式以图中所示座椅转盘详细说明其驱动传动原理，应当理解，其中的驱动部件及中间传动部件等具体尺寸参数，对本申请请求保护的技术方案未构成实质性限制。
请参考图1和图2，其中，图1为本实施方式所述座椅转盘的整体结构示意图，图2为该座椅转盘的装配爆炸示意图。图中所示，该座椅转盘主要由旋转机构100、锁止机构200、驱动部件(优选为电机300)和传动连动机构400构成，其中，旋转机构100具有转动适配的环形上旋转盘101和环形下旋转盘103，这里，组装完成后，上旋转盘101与座椅(图中未示出)底部连接，下旋转盘103可与座椅滑轨或者直接与车身(图中未示出)连接；例如但不限于，上旋转盘101通过上连接螺栓102与座椅固连，下旋转盘103通过下连接螺栓104与滑轨或车身固连。
在电机300的驱动下，该上旋转盘101可相对于下旋转盘103转动，并通过锁止机构200锁止和解锁上旋转盘101相对于下旋转盘103的工作位置；应当理解，“工作位置”是指根据乘员需求调定座椅角度后，上旋转盘101所处的相对位置，锁止该工作位置可确保使用过程中的乘员安全。
本方案中，采用传动连动机构400将电机300提供的动力分别传递至上旋转盘101和锁止机构200的解锁端。
其中，主传动件401与电机300的输出端同轴转动。具体地，电机300的安装固定可以采用不同的方式实现，例如，可通过螺钉301固定在支架302上，支架302通过焊接或者其他方式固定在下旋转盘103上。主传动件401同样也可采用不同的方式实现，如图2所示，主传动件401通过花型轴303与电机300以及支架302相连。电机300启动后，通过花型轴303带动主传动件401进行旋转。为保证主传动件401在传动中的平稳性，在主传动件401上侧固定有支架304。支架304通过螺钉305固定在支架302上。请一并参见图4，该图示出了下旋转盘及关联构件的装配关系。
其中，与主传动件401传动适配的解锁从传动件402和旋转从传动件403，分别传递动力至上旋转盘101和锁止机构200的解锁端，旋转从传动件403固定设置在相邻解锁从传动件402之间的所述上旋转盘上。图中所示， 设置两个解锁从传动件402和一个旋转从传动件403，本文以该优选设置详细说明连动工作机理。
请一并参见图3，图3示出了上旋转盘及关联构件的装配关系。本方案中，解锁从传动件402可相对于上旋转盘101在解锁工作位和锁止工作位之间滑动切换，锁止状态下的主传动件401与两个解锁从传动件402中的一者适配于锁止工作位；图1所示即为一锁止状态，此状态下座椅相对于底座滑轨或车身保持确定的相对位置。
其中，牵拉部件404具有第一端和与该第一端连动的两个第二端，第一端牵拉于锁止机构200的解锁端，每个第二端分别牵拉于相应的解锁从传动件402；这里，牵拉部件404可以优选通过连接器4041连动的拉索实现，第一拉索4042可通过连接器4041分别连动和两根第二拉索4043，牵拉于锁止机构200解锁端的第一端形成于第一拉索4042的自由端，牵拉于相应解锁从传动件402的第二端形成于第二拉索4043的自由端。
在此基础上，解锁从传动件402滑动切换具有预设行程，该“预设行程”需要满足锁止机构200的解锁端位移；也就是说，解锁从传动件402自锁止工作位滑动切换至解锁工作位时，基于牵拉部件404的设置，锁止机构200可完成解锁。
同时，解锁从传动件402在主传动件401的带动下自锁止工作位滑动至解锁工作位时，主传动件401可带动解锁从传动件402下游侧的旋转从传动件403转动。可以理解的是，主传动件401带动锁止机构200完成解锁后，再带动上旋转盘101实现座椅角度的调整，也就是说，采用一个驱动部件可间歇地带动解锁和旋转构件，实现自动解锁、转动功能。
组装完成后，常态下转盘处于锁止状态。当需要自动调节转动座椅时，启动电机300，首先通过主传动件401带动解锁从传动件402相对于上旋转盘101滑动切换至解锁工作位，并通过牵拉部件404实现锁止机构200的解锁操作，解锁过程中上旋转盘101保持不动；完成解锁阶段的驱动后，电机300继续转动进入转动阶段，接下来，通过主传动件401带动旋转从传动件403及上旋转盘101转动至乘员预期到达的工作位，完成转动阶段的驱动。
另外，基于传动连动机构400采用牵拉部件404实现与锁止机构连动的结构特点，本方案同时还可采用手动操作牵拉部件404进行解锁操作，进而转动座椅，从而兼具通过手动自动解锁和驱动实现座椅的旋转调节功能。
为了进一步优化结构，主传动件401与解锁从传动件402和旋转从传动件403之间为齿啮合传动适配，可有效利用转盘内部空间，并具传动可靠的优点。如图所示，主传动件401为与电机300输出轴同轴转动的齿轮，基于功能角度需求，解锁从传动件402与旋转从传动件403分别相应设置为弧形啮合齿段。，沿周向的，解锁从传动件402的一端位于上旋转盘101的上方，另一端位于旋转从传动件403的上表面，由此进一步地，该解锁从传动件402与旋转从传动件403和上旋转盘101的上表面之间形成该滑动切换的配合副。如此设置，可最大限度地利用周向及径向装配空间，产品结构布置更加紧凑合理。
当然，也可采用这样的设计，解锁从传动件402与旋转从传动件403和上旋转盘101中的一者之间形成该滑动切换的配合副(图中未示出)，同样可以达成上述适配功能。
作为优选，该滑动切换的配合副配置为：在解锁从传动件402上开设有与其上啮合齿分度圆同心设置的弧形槽4021，旋转从传动件403和上旋转盘101的上表面具有与相应弧形槽4021相适配的导向柱4022，通过弧形槽4021的弧长设计确保“预定行程”，同时确保解锁从传动件402的解锁及复位锁止过程均具有良好的位移轨迹。这里，弧形槽4021设置为至少两个，且至少两个弧形槽4021的在径向上错开设置，可进一步规避传动过程中可能产生的偏摆，确保位移轨迹。
实际上，也可反向设置弧形槽和导向柱，旋转从传动件和/或上旋转盘的上表面可开设有与其上啮合齿分度圆同心设置的弧形槽，相应地，导向柱设置在解锁从传动件上(图中未示出)，应当理解，只要能够满足获得良好位移轨迹的功能需要均在本申请请求保护的范围内。
为了提升转盘工作性能，可以针对解锁从传动件402和旋转从传动件403作进一步优化。结合图3所示，解锁从传动件402位于相邻旋转从传动件403上，解锁从传动件402的解锁啮合齿4023的下游侧具有旋转同步啮合齿 4024，该旋转同步啮合齿4024与旋转从传动件403的上游端啮合齿4031轴向叠置，以同步带动上旋转盘101转动。本文中所使用的“上游”、“下游”等方位词，是以相应构件与主传动件401的传动适配顺序为基准定义的，上述方位词仅用于清楚示明构件间动态配合关系，而非构成对本方案实质内容的限制。
如此设置，完成解锁阶段的解锁从传动件401继续转动，从而继续带动锁止机构20的解锁端位移，确保其保持良好的复位姿态；另外，其上的旋转同步啮合齿4024与旋转从传动件403的上游端啮合齿4031同步带动上旋转盘101转动，在座椅转动初始时刻具有良好的承载能力，确保顺畅实现座椅的旋转调节功能。
需要说明的是，用于锁止和解锁上旋转盘101相对于下旋转盘103的工作位置的锁止机构200，可以根据需要采用适应牵拉部件404的不同结构实现方式。例如但不限于图中所示优选方式。
请一并参见图5，该图为图1的A-A剖视图。
结合图1-3和图5所示，该锁止机构200主要包括解锁片201、锁止销202和锁支架203，其中，解锁片201通过枢接轴204与上旋转盘101枢接，与牵拉部件404的第一端适配的解锁端位于该解锁片201上；锁止销202的一端与枢接轴204旁侧的解锁片201固定连接，其另一端穿过上旋转盘101上开设的通孔1011与锁止槽2031卡合适配；设置有该锁止槽2031的锁支架203固定设置在下旋转盘103上。其中，锁止销202与锁止槽2031的卡合适配具体配置为：牵拉部件404的第一端牵拉该解锁片201，以带动锁止销202自锁止槽2031中解锁脱离，通过第一拉索4042可拉动锁止机构200来实现上、下旋转盘的解锁。
可以确定的是，该锁止槽2031的开口侧还应当满足锁止销202的脱离空间需求。此外，上旋转盘101上的通孔1011为与枢接轴204同心设置的弧形通孔，且锁止销202在该弧形通孔1011中的行程大于或等于锁止销201自锁止槽2031中解锁脱离的行程。
另外，图中所示的锁止机构200还包括套装于枢接轴204上的复位扭簧205，以具备锁止复位功能。该复位扭簧205的两个施力端分别与解锁片201 和上旋转盘101连接，优选预形变置于两者之间，以保持锁止状态；在解锁片201带动锁止销202解锁脱离的过程中储存弹性变形能。这样，当主传动件401与解锁从传动件402之间脱离啮合时，该复位扭簧205拉动解锁片201和锁止销202复位至锁止位，与此同时，通过第二拉索4043牵拉相应的解锁从传动件402滑动切换至锁止位。
进一步地，可以在上旋转盘101和下旋转盘103之间设置加强盘105，具体地，该加强盘105与上旋转盘101固定连接以围合环形密闭腔体，增强了结构的强度。相应地，加强盘105上开设有与上旋转盘101上的通孔1011轴向相对设置的通孔1051，以便锁止销202穿过。
同时设置一压盘106，与加强盘105组配后的上旋转盘101同心装入下旋转盘103中，再将压盘105固联到下旋转盘103上。该压盘106上端具有径向外伸的限位环1061，压盘106的下端穿过上旋转盘101和加强盘105的中部与下旋转盘103固定连接，通过限位环1061与上旋转盘101的上表面形成轴向限位。由此，除压紧上下旋转盘的作用外，压盘105还具备防止脱落的作用。
需要说明的是，压盘105与下旋转盘103固联，可以视为一个整体。为了叙述的方便，我们不妨按照上下旋转盘的运动状态，将加强盘105和上旋转盘101称为“转子”，下旋转盘103以及压盘106形成的整体称为“定子”。由于“转子”与“定子”间具有相对转动，需要提高两者间旋转运动的平顺流畅性。
首先，“转子”与“定子”在竖直方向有两处接触位置，分别是压盘106与上旋转盘101接触，加强盘105与下旋转盘103接触，可在这两处分别加入滑动元件。这里，滑动元件可以由一系列的钢球、滚柱或其他滚动元件与固定保持架进行装配，形成一个整体；也可以是塑料或其他表面具有润滑涂层的金属件。本方案优选采用表面涂有特殊材料的金属片，即上、下摩擦片(107、108)，其中，上摩擦片107设置在压盘106的限位环1061与上旋转盘101之间，下摩擦片108设置在加强盘105的外周边沿与下旋转盘103之间。
另外，在水平方向上，“转子”与“定子”间同样存在接触，为此，可在上旋转盘101的中部孔壁与压盘106外周面之间设置摩擦环109，优选采用塑料摩擦垫圈，在获得良好摩擦性能的基础上，降低产品成本。
此外，还可以设置上下防脱件。结合图中所示，至少两个上防脱件110间隔固定设置在上旋转盘101的外周，每个上防脱件110的板体向下延伸后折弯向上形成的上钩部；至少两个下防脱件111间隔固定设置在下旋转盘103的外周，每个下防脱件111的板体向上延伸后折弯向下形成的下钩部；其中，每个上防脱件110与下防脱件111轴向相对设置，且上钩部与下钩部可周向插装形成轴向限位副。防脱钩的配合，使得转盘在运动或是颠簸时不会有上下脱离的情况发生。
下面结合图1和图6至图8，具体说明本实施例所示座椅转盘的转动过程动态配合关系。
首先，如图1所示的初始锁止状态。当电机300启动后，其输出端通过花型轴303带动主传动件401进行旋转，主传动件401与其中一个解锁从传动件402进行啮合传动。解锁从传动件402上具有弧形槽4021，使解锁从传动件402顺着弧形槽4021进行转动，过程中，解锁从传动件402上固定设置的第二拉索4043，解锁从传动件402的运动会带动第二拉索4043，使第二拉索4043拉动第一拉索4042，从而第一拉索4042可带动锁止机构200绕着枢接轴204进行转动，使锁止销202与锁支架203的锁止槽2031脱离，实现转盘解锁。
接下来，如图6所示，解锁从传动件402继续转动直至弧形槽4021与导向柱4022碰撞后，通过导向柱4022带动上旋转盘101与加强盘105围绕中心开始转动。如图7所示，当转动到解锁从传动件402与主传动件401完全脱离后，锁止机构200受到复位扭簧205的回复力的作用进行复位，带动第一拉索4042运动，第一拉索4042又带动第二拉索4043，第二拉索4043带动解锁从传动件402进行复位。
此后，上旋转盘101与加强盘105继续进行转动直至锁止机构200的锁止销202与锁支架203的斜边碰撞后，在惯性力的作用下，锁止销202沿着锁支架203的斜边进行滑行，直至锁止销202滑入锁支架203的卡槽中进行锁止。 如图8所示，此时主传动件401达到与另一解锁从传动件402啮合的状态。以此往复，可进行反向转动调节。
需要说明的是，本实施方式提供的上述实施例，并非局限于图中所示在采用两个解锁从传动件402和一个旋转从传动件40，并可实现图示大致180度的座椅角度调节，实际上还可以根据具体角度调节需要设置为多个；具体地，与主传动件401传动适配地采用N+1个解锁从传动件和N个旋转从传动件，其中，N为正整数。可根据具体座椅转动角度的功能设定，确定周向依次设置的解锁从传动件和旋转从传动件的设置数量及相对位置；如此设置，能够满足不同乘员的实际使用需求，可进一步提升用户体验。应当理解，只要核心构思与本方案一致均在本申请请求保护的范围内。
除前述座椅转盘外，本实施方式还提供一种包括如前所述座椅转盘的座椅，其中，上旋转盘与座椅本体的底部连接即可。这里，座椅的其他功能构成可以采用现有技术实现，故本文不再赘述。
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。
