具体实施方式
为能进一步了解本发明的特征、技术手段以及所达到的具体目的、功能，下面结合附图与具体实施方式对本发明作进一步详细描述。
如图1所示，车门驱动机构安装固定在车门101中部靠铰链107侧，即安装于车门原限位器位置。在电动工况时，车门驱动机构102收到ECU控制器105开门/关门信号时，内部电机3开始运转，通过驱动机构102内部传递至丝杆17旋转，推动丝杆螺母19直线运动，从而使推杆21产生推/拉力。而车门驱动机构102固定于车门，车身支架103固定于车身，推杆21伸缩从而使车门101进行电动开/关动作。
如图2所示，电机3一端连接电路组件1，依次连接电机胶垫2，电机隔距套36。另一端设有减速器4，减速器4内部有内花键输出，连接电机轴5，电机3旋转经减速器4传递至电机轴5，从而使电机轴5旋转。电机轴5连接制动器6，通过ECU控制器105输出电压加至制动器6上，从而使制动器6产生制动扭矩，从而改变机构内阻。电机轴5设有密封圈槽，装配有第一密封圈7，中间设有花键与第一传动齿轮8相连，端部设有轴承限位台阶，与第一轴承13相连。制动器6设有卡槽与壳体9连接，壳体9端部与壳体盖12通过定位止口及连接螺钉11相连，将壳体9与壳体盖12紧固，壳体盖12设有密封圈槽，装配第二密封圈10。传动齿轮包括第一传动齿轮8、第二传动齿轮14以及第三传动齿轮36，第一传动齿轮8旋转后通过第二传动齿轮传递第三传动齿轮36并传递至丝杆17处，使丝杆17产生旋转运动，丝杆17依次设有轴承台阶与第二轴承16相连，设有花键与第三传动齿轮36相连，设有密封圈槽与第三密封圈18相连。丝杆中间设有螺纹，与丝杆螺母19相连，丝杆螺母19内部设有螺纹部分，设有销轴20与推杆21相连，销轴20设有止退机构，防止销轴退出。丝杆17旋转运动传递至丝杆螺母19，丝杆螺母19导向块使其沿丝杆17轴向运动，从而使推杆21推拉运动。推杆21连接销轴 20亦可产生旋转运动，调整推杆与车门夹角。丝杆17另一端设有轴承台阶，连接第三轴承23，依次连接第一挡圈29固定第三轴承23。第三轴承23通过轴承座22与轴承垫块25固定于壳体9上，壳体9、轴承座22、安装座27之间依次设有密封垫24、26，密封垫26设有密封唇口与推杆21密封，下部设有线束密封结构，保证密封功能。推杆21设有限位机构，最大伸出时与安装座27边缘处进行最大行程限位。推杆21另一端连接有关节轴承33，通过第二挡圈34进行限位，关节轴承33中间连接车身支架32，车身支架32与车身相连，固定推杆21一端。安装座27连接固定螺钉28，将驱动机构102固定于车门，推杆21伸缩运动，车身支架32连接车身，从而带动车门101旋转电动开闭。
如图3所示，优选的，电机轴5设有密封圈槽，并装配有第一密封圈，中间设有花键与第一传动齿轮8相连，端部设有轴承限位台阶，并与第一轴承相连，电机轴5连接有阻尼器37，这里也可以将制动器6替换成阻尼器37，这样通过阻尼器37可以保证了断开电机减速器时，仍然可全角度悬停；在驱动机构制造过程中，保证其内阻一致性，即保证手动开关门力值、产品功能等一致性；相比较制动器，其成本更低，同时可规避制动器的不稳定性。
如图4所示，这里在可以将制动器6和阻尼器37进行省略，电机轴5直接连接第一传动齿轮8，这里无制动器6或阻尼器37，大大减小驱动机构的总长度，适用的车型更广泛。
如图5所示，壳体9由第一壳体38和第二壳体39组合拼接而成，电机3、减速器4、电机轴5、制动器6和传动齿轮组安装在第一壳体38中，丝杆17和丝杆螺母19安装在第二壳体39中，第一壳体38上具有组合平台部40，第二壳体39位于组合平台部40上，第一壳体38的长度为固定长度，第二壳体39的长度为可变长度，这里将长度固定的第一壳体38与长度经常变化的第二壳体39分开，当因不同车型需改变机构长短时，通过只改变丝杆壳体部分的长短时，能够更方便快捷，成本和开发周期更具优势，利于改变机构的总长度，成本低、方便快捷，第一壳体38呈L型，第一壳体38包括电机安装部381和齿轮容纳部382，电机3、减速器4、电机轴5、制动器6安装在电机安装部381内，传动齿轮组安装在齿轮容纳部382内，第二壳体39包括有壳体部，壳体部内部具有中空部391，丝杆17和丝杆螺母19位于中空部391内，推杆21的一端伸入中空部391中并与丝杆螺母19连接，推杆21的另一端伸出壳体部与车身支架103连接。
为了做到推杆可以自动调心的、可以轴向限位，推杆21的两侧端部开设有铰接孔，在两侧端部的铰接孔处中至少包含一个关节轴承33，推杆21上设有限位部41，限位部41为直面或圆弧面中的其中一种，限位部41位为设置在推杆21的单侧或者上下两侧，推杆21为直线状或者曲线状，如图6所示，推杆21与丝杆螺母19配合处具有铰接二孔43，推杆21与车身支架配 合处具有铰接一孔42，铰接二孔43上设置有关节轴承33，铰接一孔42上设置有两个衬套44，这里将关节轴承33改变到丝杆螺母处实现调心，如图7所示，也可以两侧都是关节轴承33结构，推杆21与丝杆螺母19配合处具有铰接二孔43，推杆21与车身支架32配合处具有铰接一孔42，铰接二孔43上设置有关节轴承33，铰接一孔42上设置有关节轴承33。
电动工况：车门驱动机构总成102收到控制信号电动开门/关门时，电机3通电开始运转，经过减速器4连接的电机轴5，从而使第一传动齿轮8旋转运动，传动至丝杆17进行旋转运动，丝杆17上设有丝杆螺母，从而将丝杆17螺旋运动转换为丝杆螺母19直线运动，将拉杆21进行推拉，从而将车门总成进行开/关动作。
手动工况：电机3电源信号与整车电源保持断开，车门上传感器106可以检测车门进行是否进行手动开关门，是否进行开启/关闭信号。详细如下：
1、人员未进行手动开关门时，车门传感器106检测到手动开关门。极限工况(上/下坡)车门总成101若出现自动下落/开启时，ECU控制器102通过算法计算，输出合适的电压对制动器6进行制动扭矩控制，制动器6与电机轴5相连，增大驱动机构内阻，从而阻止车门自动下落/开闭。反之，常规状态，车门传感器106未检测到车门开启/关闭时，制动器6内部摩擦组件断开，从而减小驱动机构102内阻，从而实现电控调整驱动机构102内阻。
2、人员进行手动开关门时，车门传感器105检测到手动开关门，详细如下：
①、随动：车门传感器106检测到快速手动开关车门时，ECU控制器105发出自动开/关门信号，方向与人操作车门总成101相同，从而车门驱动机构102进行电动开/关门。
②、很轻的手动操作力：车门传感器106检测到缓慢手动开关车门时，ECU控制器105发出离合器3断开信号，从而保持较轻的缓慢手动操作力。
另外车门内/外还设有障碍物检测传感器，车门总成开启/关闭过程中，提前检测障碍物。防止撞击/夹击操作人员或其他障碍物，造成人员伤害或车门损坏。通过ECU控制器105对车门驱动机构102中，通过电机3电流进行检测，从而推断出车门撞击/夹击情况。
以上实施例仅表达了本发明的一种或几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
