具体实施方式
以下结合附图和具体实施方式来进一步描述本发明。
参见图1至图6，图中所示的后排座椅电动翻折兼角度调节机构，包括：电机总成10、齿板动盘20、齿板定盘30、限制块40、拉索驱动轮50、解锁拉索60、锁总成70、舒适型调节机构80和罩盖100。
电机总成10固定在靠背骨架90上，电机总成10具有一同步输出轴11，在同步输出轴11的末端固定有一跟随同步输出轴11同步转动的电机同步杆齿轮12并设置有一内螺孔13。
在靠背骨架90的合适位置上固定有一安装板91，在安装板91上开设有一 第二轴孔92并锚固有三个螺母92a、92b、92c。
在罩盖100上开设有三个罩盖安装螺栓孔110、120、130和一个限制块透出孔140，三个罩盖安装螺栓孔110、120、130的位置与安装板91的三个螺母92a、92b、92c位置一一对应。
特别参见图4a和图4b，齿板动盘20呈扇形结构，在齿板动盘20的外周设置有第一齿环21并在齿板动盘20的圆心开设第一轴孔22，另外在第一齿板动盘20的一盘面23上设置有一偏心轴24。在齿板动盘20的两条扇形边上中用以限定靠背骨架90翻平位置和使用状态位置的两个极限位置25、26。
特别参见图3、图5a和图5b、图9，齿板定盘30也呈扇形结构，在齿板定盘30的外周设置有第二齿环31并在齿板定盘30的圆心固定有一轴套32。在轴套32朝向齿板定盘30的一端内设置有内螺孔32a。另外在齿板定盘30的盘面上设置有一偏心腰形孔33。第二齿环31的圆心角小于第一齿环21的圆心角。
在拉索驱动轮50上开设有一中心孔51和一偏心拉索孔52。
装配时，在齿板动盘20的第一轴孔22内套入第二限位隔衬套25，在安装板91的第二轴孔92内套入第一限位隔衬套93。然后将齿板定盘30上的轴套32穿过第二限位隔衬套25并同时使得齿板动盘20上的偏心轴24插入到齿板定盘30的偏心腰形孔33中。偏心轴24伸入偏心腰形孔33内并能在偏心腰形孔33内运动。
接着将台阶螺栓94穿过第一限位隔衬套93旋入到轴套32的内螺孔32a中，从而使得齿板动盘20和齿板定盘30轴设在安装板91上并且使得齿板定盘30与齿板动盘20同心设置。齿板动盘20和齿板定盘30安装好以后，由于第二齿环31的圆心角小于第一齿环21的圆心角，即第二齿环31的弧长小于第一齿环21的弧长并且两者弧长差值大于等于解锁拉索60的解锁行程。齿板定盘30与齿板动盘20之间通过第二限位隔衬套25进行轴向限位，齿板动盘20与安装板91之间通过第一限位隔衬套93进行轴向限位。
在没有解锁时以及解锁过程和解锁完成前，电机同步杆齿轮12只与第一齿环21相啮合，而不与第二齿环31相啮合。只有在解锁后，电机同步杆齿轮12才会同时与第一齿环21和第二齿环31啮合，驱动靠背骨架90进行翻折运 动。
接着在拉索驱动轮50的中心孔51内套入衬套53，然后将拉索驱动轮50的中心孔51连同衬套53一起套在同步输出轴11的末端上，再将拉索驱动轮安装螺栓54穿过衬套53旋入到同步输出轴11末端的内螺孔13中，紧固后即可使得拉索驱动轮50固定同步输出轴11的末端上，以便拉索驱动轮50跟随同步输出轴11同步转动。
接着将解锁拉索60的驱动端61固定在拉索驱动轮50的偏心拉索孔52中，使得解锁拉索60的驱动端61与拉索驱动轮50偏心连接。
将限制块40固定在轴套32背离齿板动盘30的一端上，限制块40的中心与齿板定盘30的轴套32为通轴，焊接固定；也可以把限制块40与齿板定盘30制造为一个零件。
接着将三颗罩盖安装螺栓150、160、170对应穿过三个罩盖安装螺栓孔110、120、130和三个罩盖限位套筒180、190、200后旋入到安装板91的三个螺母92a、92b、92c位置一一对应，即可使得罩盖100安装在安装板91上，使得罩盖100将齿板定盘30、齿板动盘20、同步输出轴11、电机同步杆齿轮12罩住。拉索驱动轮50和解锁拉索60的驱动端61位于罩盖100之外，罩盖限位套筒180、190、200用于限定罩盖100与安装板91之间的距离；其中一个罩盖限位套筒200作为靠背骨架90在翻平与使用状态之间翻折的限位挡点。
解锁拉索60的输出端62延伸出罩盖100。罩盖100安装好以后，限制块40透出罩盖100上的限制块透出孔140而固定安装在车身上，以限制齿板定盘30转动。
锁总成70固定在靠背骨架90上部的一角上，锁总成70可以采用类似目前现有技术中的地板锁。
解锁拉索60的输出端62与锁总成70连接，在解锁拉索60拉紧时，带动锁总成70解锁。
舒适型调节机构80安装在车身上。该舒适型调节机构80为电动多段锁81或手动多段锁82。电动多段锁81或手动多段锁82为现有技术，其中电动多段锁81采用丝杆螺母机构驱动一锁钢丝81a进行运动，锁钢丝81a作为舒适型调节机构80的驱动端。
舒适型调节机构80的驱动端与锁总成70锁止连接，锁总成70解锁后，舒适型调节机构80的驱动端即锁钢丝81a能够脱离锁总成70，使得所述靠背骨架90能够进行翻折。
本发明的座椅，包含上述后排靠背一键翻折兼舒适型调整整体性机构。
参见图7至图9，在初始位置时，由于齿板定盘30上的第二齿环31的圆心角小于齿板动盘20的第一齿环21的圆心角，即齿板定盘30上的第二齿环31的弧长小于齿板动盘20的第一齿环21的弧长并且两者弧长差值大于等于解锁拉索60的解锁行程，此时电机同步杆齿轮12只与第一齿环21相啮合，而不与第二齿环31相啮合。解锁拉索60处于松弛状态，舒适型调节机构80的驱动端即锁钢丝81a被锁总成70锁住。此状态下，座椅靠背可以通过舒适型调节机构80实现舒适型调节功能
参见图10至图12，需要对靠背骨架90进行翻折时，启动电机总成10，由于电机同步杆齿轮12只与齿板动盘20上的第一齿环21相啮合，而不与齿板定盘30上的第二齿环31相啮合，电机同步杆齿轮12和拉索驱动轮50在电机总成10驱动下同时转动，电机同步杆齿轮12通过啮合驱动齿板动盘20转动，同时拉索驱动轮50拉动解锁拉索60，解锁拉索60从松弛状态逐渐到拉紧状态，直至走完解锁行程，解锁拉索62拉动锁总成70上的解锁锁钩解锁锁总成70，使得锁总成中的解锁锁钩与调节机构80分离脱开。在解锁拉索60对锁总成70解锁过程中，电机同步杆齿轮12驱动齿板动盘20转动。由于齿板定盘30上的第二齿环31的弧长小于齿板动盘20的第一齿环21的弧长并且两者弧长差值大于等于解锁拉索60的解锁行程，在解锁拉索60对锁总成70解锁完成时，齿板动盘20转动到极限位置26与罩盖限位套筒200接触，齿板动盘20的第一齿环21上的齿与齿板定盘30上的第二齿环31上的齿重合，同时齿板动盘20上的偏心轴24转动到与齿板定盘30上的偏心腰形孔33的一端。
参见图13至图15，在解锁拉索60对锁总成70解锁完成后，电机同步杆齿轮12继续转动，此时由于齿板动盘20转动到极限位置26与罩盖限位套筒200接触加上齿板动盘20上的偏心轴24转动到与齿板定盘30上的偏心腰形孔33的一端，齿板动盘20不会再继续单独转动，电机同步杆齿轮12会带动靠背绕着齿板定盘30与齿板动盘20转动，使得靠背翻转。
此时，由于齿板动盘20和齿板定盘30同步与车身固定不同，在齿板动盘20上的第一齿环21与齿板定盘30的第二齿环31一起与电机同步杆齿轮12同时啮合时，电机同步杆齿轮12通过同步输出轴11和电机总成10带动靠背骨架90进行翻折，直到靠背骨架90翻平。在靠背骨架90翻平后，齿板动盘20的极限位置25与罩盖限位套筒200接触，使得齿板动盘20的极限位置25与罩盖限位套筒200构成靠背骨架90在翻平后的硬挡点。
参见图16至图18，需要将靠背骨架90翻起至使用状态时，电机总成10反向工作，通过同步输出轴11驱动电机同步杆齿轮12反向转动。此时，由于齿板动盘20和齿板定盘30同步与车身固定不同，电机同步杆齿轮12通过齿板动盘20上的第一齿环21与齿板定盘30的第二齿环31一起啮合，带动靠背骨架90从翻平状态向上翻起至使用状态。
在靠背骨架90翻起至使用状态后，电机同步杆齿轮12重新回到只与第一齿环21相啮合，而不与第二齿环31相啮合的状态。解锁拉索60从拉紧状态逐渐到松弛状态，直至走完齿板动盘20的运动行程，齿板动盘20在极限位置26与罩盖限位套筒200的相互作用下停止旋转，同时电机在转动力的作用下，驱动锁总成锁70上的解锁锁钩与舒适型调节机构80上的锁钢丝81a锁止结合，锁住舒适型调节机构80。在锁总成70处于锁止状态，拉动的解锁拉索60线束输出端62被松开，解锁拉索60重新处于松弛状态。
结合参见图19至图22，舒适型调节机构80的驱动端即锁钢丝81a被锁总成70锁住后，启动舒适型调节机构80，舒适型调节机构80的驱动端即锁钢丝81a即可带动靠背骨架90进行舒适型调整。该舒适型调整可以快速使得靠背骨架90在任意位置进行运动。
本发明能实现锁总成解锁后，靠背一键翻折抬起，同时实现一个电机驱动锁总成解锁和靠背翻折，以及实现锁总成上锁后，对靠背进行舒适性角度调节。本发明还具有在翻平后的位置硬挡点功能。
