请参阅图1至图4，本申请实施方式的管柱连接机构100用于车辆200。管柱连接 机构100包括滑动导轨机构10和预紧调节机构20。滑动导轨机构10用于连接车辆200的管柱202和车架203，以使得管柱202能够相对车架203移动进而进行伸缩调节。预紧调节机构20包括螺母21、导杆22和弹簧23，弹簧23套设在导杆22上并且弹簧23的两侧分别抵持滑动导轨机构10和导杆22，螺母21和导杆22连接车架203，螺母21能够带动导杆22相对车架203移动以调节弹簧23对滑动导轨机构10的压力。
在本申请实施方式的管柱连接机构100中，管柱202和车架203可以通过滑动导轨机构10连接保证管柱202能够相对车架203移动顺畅。同时，可以通过调节螺母21以改变对滑动导轨机构10的预紧力，进而可以降低摩擦力，提高电机调节的效率，降低电机的能源消耗。另外，通过螺母21的调整，可以对管柱202的整体刚性进行一定的调节，如需较高的管柱202刚性，可提高车架203和管柱202之间的夹紧力，如需降低管柱202的整体刚性，可适当降低车架203和管柱202之间的夹紧力。
在相关技术中，管柱在进行伸缩调节时，管柱和支架的摩擦为滑动摩擦，随着润滑剂的逐渐变质和消耗，管柱和支架之间的相对运动的摩擦力会变得越来越大，操作的手感变差，并且在伸缩调节的过程中会产生噪音。另外，管柱在移动的过程中用于出现相对旋转或者错位的问题。
在本申请实施方式中，管柱连接机构100可以通过预紧调节机构20调节车架203和管柱202之间的间距，避免车架203和管柱202之间出现较大的间隙，同时可以通过调节螺母21以改变对滑动导轨机构10的预紧力，这样可以降低管柱202和车架203之间的摩擦力，也就是降低对滑动导轨机构10压力，避免出现噪音，同时保证操作的手感变差。另外，管柱202相对车架203的移动通过电机控制时，减小摩擦力可以提高电机调节的效率，降低电机的能源消耗。
另外，管柱连接机构100可以通过滑动导轨机构10限定管柱202和车架203的相对运动，有限位和导向的作用，避免管柱202在移动的过程中相对车架203出现错位或者旋转的问题。当然，在本申请实施方式中，弹簧23还可以通过其他弹性件代替，以实现相同的功能，具体在此不做限定。
请参阅图3和图5，在某些实施方式中，滑动导轨机构10包括直线滚针轴承11、导轨12和压紧块13，直线滚针轴承11连接管柱202，压紧块13连接车架203，压紧块13抵持导轨12，并使得导轨12压紧直线滚针轴承11。导杆22至少部分地伸入在压紧块13中，弹簧23的一端抵持压紧块13。
如此，压紧块13可以将导轨12压紧在直线滚针轴承11上，导轨12可以相对直线滚针轴承11移动，使得滚针转动，进而产生滚动摩擦。滚动摩擦的摩擦力较小，可 以有效减少对润滑脂的损耗，避免出现噪音的问题。同时螺母21可以设置在压紧块13中，并可以相对压紧块13转动以抵持导杆22进退，进而控制弹簧23的压缩量，实现车架203和管柱202之间的预紧力的调整。
具体地，直线滚针轴承11可以连接管柱202，压紧块13可以与车架203连接，同时压紧块13的另一侧可以与导轨12直接连接，以保证导轨12可以压在直线滚针轴承11上。此时，直线滚针轴承11上的滚针与导轨12直接接触，并且在车架203和导轨12相对管柱202移动时，滚针可以产生滚动，使得滚针和导轨12之间产生滚动摩擦。另外，弹簧23可以避免导杆22直接接触压紧块13，从而避免出现刚性碰撞损伤。
请参阅图2和图3，在某些实施方式中，直线滚针轴承11和导轨12呈V形状并相互配合贴合在一起，压紧块13包括箭头部131，箭头部131伸入导轨12的V形缺口以压紧导轨12和直线滚针轴承11。
如此，直线滚针轴承11和导轨12都呈V形状，保证两个元件可以贴合紧密，同时压紧块13在沿着箭头部131指向的方向对导轨12施加压力时，可以将压力转换为两个面的分力，从而避免压紧块13作用下导致导轨12相对直线滚针轴承11偏移错位的问题。
进一步地，请参阅图2和图3，在某些实施方式中，管柱连接机构100还包括调节底板30，调节底板30固定连接管柱202，调节底板30形成有V形连接部31，V形连接部31用于容置并连接直线滚针轴承11。
如此，V形连接部31用于容置并连接直线滚针轴承11，避免直线滚针轴承11在压紧块13和导轨12压力的作用下与调节底板30连接错位。
具体地，调节底板30可与管柱202固定连接，V形连接部31可以连接V形的直线滚针轴承11，使得直线滚针轴承11可以与调节底板30保持固定的位置。此时，箭头部131和导轨12的V形凸出部可以伸入直线滚针轴承11之间并抵持滚针。这样，可以避免压紧块13在受到偏上或者偏下的受力时，导轨12与直线滚针轴承11错位。
请参阅图3和图5，在某些实施方式中，压紧块13远离导轨12的一侧形成有梯形导向孔132，导杆22和弹簧23均至少部分地伸入梯形导向孔132中。
如此，导杆22可以伸入在梯形导向孔132中间的孔中，弹簧23可以抵持在梯形导向孔132的梯形面上，进而保证对导杆22和弹簧23的限位。
具体地，在压紧块13远离导轨12的一侧形成有梯形导向孔132，导杆22和弹簧23均至少部分地伸入梯形导向孔132中，这样，可以通过调节螺母21以抵持导杆22移动，导杆22又抵压弹簧23，进而控制弹簧23的压缩量。示例性地，在一个例子中， 在螺母21向靠近调节底板30的方向移动时，导杆22抵压弹簧23使得弹簧23压紧，弹簧23可以抵持在梯形导向孔132的梯形面以抵压压紧块13，使得压紧块13和导轨12对直线滚针轴承11的压力增大，可提高车架203和管柱202之间的夹紧力，以使得管柱202有较高的刚性。在另一个例子中，在螺母21向远离调节底板30的方向移动时，使得弹簧23松弛，进而使得压紧块13和导轨12对直线滚针轴承11的压力变小，可减小车架203和管柱202之间的夹紧力，以使得管柱202有较低的刚性。
进一步地，当需要对摩擦力进行调整时，可通过预紧调节螺母21的轴向调整来增大或减少直接调节摩擦力，由于增加或减少压紧力也会影响到整个机构的整体刚性，因此可通过调整压紧力来调节整个管柱202和车架203的固有频率来适配相应的系统。
请参阅图2和图3，在某些实施方式中，直线滚针轴承11和导轨12的V形缺口的角度小于90°。如此，避免V形缺口的角度太大，导致滑动导轨机构10的元件滑出V形缺口的问题。
具体地，通过V形直线滚针轴承11和导轨12替代了原来的滑轨导槽，降低了滑动摩擦力，转变为滚动摩擦，简化了结构。同时可通过调节螺母21和弹簧23来调整车架203和管柱202之间夹紧力对管柱202整体的刚性进行调节，使得管柱202和车架203的固有频率合适，避免产生共振损害元件的问题。V形缺口的角度小于90°，限位了直线滚针轴承11、导轨12和压紧块13的位置，V形导轨12限制了管柱202的相关自由度，管柱202只能随着调节底板30进行直线移动，在工作时不会翻转错位的问题。
请参阅图1和图3，在某些实施方式中，管柱连接机构100还包括支架40和安装底板50，安装底板50连接车架203，支架40固定连接安装底板50，预紧调节机构20设置在支架40上。
如此，支架40与调节底板30相对设置，以使得预紧调节机构20设置在支架40上时，导杆22和弹簧23可以部分地伸入至压紧块13中。这样，管柱202可以通过本申请实施方式的管柱连接机构100与安装底板50连接，管柱202可以设置在管柱连接机构100远离安装底板50的一端，使得管柱202可以和车架203连接，保证连接的稳定性。
进一步地，请参阅图3和图5，在某些实施方式中，支架40上形成有螺纹孔41，螺母21与螺纹孔41通过螺纹连接，螺母21相对支架40转动以带动导杆22相对支架40移动以调节弹簧23对滑动导轨机构10的压力。
如此，螺母21与螺纹孔41通过螺纹连接配合，以使得用户可以定量调节螺母21 抵持导杆22旋入的距离，进而可以改变弹簧23的压缩量，以实现对压紧块13与导轨12和直线滚针轴承11压力的调节。
再进一步地，请参阅图2和图3，在某些实施方式中，支架40形成有凹槽42，滑动导轨机构10包括压紧块13，压紧块13靠近支架40的一端形成有连接部133，连接部133容置在凹槽42中。
如此，压紧块13的连接部133容置在凹槽42中，限制压紧块13的位置，避免压紧块13从凹槽42脱出错位的问题。
具体地，梯形导向孔132可以形成在连接部133上，螺母21设置在支架40上，并使得压紧块13的连接部133可以容置在凹槽42中，使得弹簧23和导杆22可以部分地伸入在梯形导向孔132中。由导杆22限制压紧块13的活动自由度，使其只能沿着导杆22的轴线移动，进行压紧或放松的操作。弹簧23安装在V形压紧块13和导轨12支架40的沉孔中，调整螺母21与支架40为螺纹连接，转动调整螺母21，通过调整螺母21的轴向移动来使导杆22压缩弹簧23来增大压紧力。
在本申请实施方式中，管柱202的调节可以通过电机控制，在支架40和管柱202之间增加V形直线滚针轴承11，管柱202和支架40之间进行伸缩调节时，由原来的滑动摩擦力转变为轴承的滚动摩擦力，降低了摩擦力，提高了电机调节时的效率，降低了电机能源的消耗，且降低了滑移时产生异响的机率。另外，滚动轴承的摩擦力可根据具体的需要，通过调整螺母21和弹簧23的压缩量进行调整，保持整个平台间摩擦力的一致性，减少电机的选型，降低开发成本，提高了管柱202的通用性和性能。这样，通过调整螺母21的调整，可以对管柱202的整体刚性进行一定的调节，如需较高的管柱202刚性，可提高支架40和管柱202之间的夹紧力，如需降低管柱202的整体刚性，可适当降低支架40和管柱202之间的夹紧力。
请参阅图4，本申请实施方式的车辆200包括车身201和上述任一项实施方式的管柱连接机构100，管柱连接机构100设置在车身201上。
在本申请实施方式的管柱连接机构100和车辆200中，管柱202和车架203可以通过滑动导轨机构10连接保证管柱202能够相对车架203移动顺畅。同时，可以通过调节螺母21以改变对滑动导轨机构10的预紧力，进而可以降低摩擦力，提高电机调节的效率，降低电机的能源消耗。另外，通过螺母21的调整，可以对管柱202的整体刚性进行一定的调节，如需较高的管柱202刚性，可提高车架203和管柱202之间的夹紧力，如需降低管柱202的整体刚性，可适当降低车架203和管柱202之间的夹紧力。
在本申请实施方式中，不限定车辆200的具体类型，车辆200可以为电动汽车，车辆200还可以为混合动力汽车，以满足多种需求。
