为了解决上述技术问题，参照图1-图3，本公开一些实施例提供一种车门铰链100。车门铰链包括安装座101。安装座101用于与车身001连接。车门铰链100还包括伸缩件107，伸缩件107与安装座101活动连接，伸缩件107远离车身001的一端用于与车门002连接。车门铰链100还包括驱动组件500，所述驱动组件与伸缩件107连接，用于驱动伸缩件107转动、并使伸缩件107沿伸缩件107的转动轴线方向往复移动。
在一些实施例中，伸缩件107的转动轴线方向与车身001宽度方向平行。安装座101可以为中空的圆筒结构，伸缩件107可以为圆柱形转轴结构，伸缩件107穿设于安装座101的中空腔内，并且与安装座101活动连接。
图1示出了一种车门铰链的使用状态示意图，此时车门002处于关闭状态；如图1所示，将车门铰链沿车身001宽度的方向设置于车身001和车门002之间，且车门铰链位于车门002的左下角。
例如，安装座101可利用螺栓固定于车身001上，伸缩件107伸出安装座101的一端也可利用螺栓固定于车门002上，伸缩件107的转动轴线方向与车身001宽度方向平行，驱动组件500为伸缩件107转动和沿自身转动轴线方向往复移动提供动力。
伸缩件107在沿车身001宽度方向往复移动的同时，可进行转动，从而安装座101和伸缩件107组成一个线性铰链结构；将安装座101沿车身001宽度方向设置于车身001和车门002之间，安装座101的一端与车身001固定连接，伸缩件107伸出安装座101的一端与车门002固定连接。
当开启车门002时，驱动组件500驱动伸缩件107沿车身001宽度方向朝向远离车身001一侧运动的同时并转动，从而使车门002在向远离车身001一侧运动的同时向上旋转，直至车门002完全打开。
当关闭车门002时，驱动组件500驱动伸缩件107沿车身001宽度方向朝向靠近车身001一侧运动的同时并转动，从而使车门002在向靠近车身001一侧运动的同时向下旋转，直至车门002完全关闭。
本公开一些实施例中，通过采用上述车门铰链，可以实现车门002的开启和关闭，相较于相关技术，本公开一些实施例将车门铰链沿车身001宽度方向布置，从而减少了安装铰链结构所占用的平行于车门002的水平空间，以适用于平行于车门002的水平方向设置空间不足的情况。
在一些实施例中，安装座101与伸缩件107之间设置有导向结构，当伸缩件107沿自身转动轴线方向往复运动时，所述导向结构用于使伸缩件107转动。
在一些实施例中，导向结构可以视为驱动组件500的一部分，在导向结构的作用下，伸缩件107在沿着车身001宽度方向移动的同时，能够发生转动，从而带动车门002开启和关闭。
本公开一些实施例中，通过在安装座101与伸缩件107之间设置导向结构，使驱动组件500只需为伸缩件107沿车身001宽度方向往复移动提供线性驱动力，从而能够简化驱动组件500的动力结构。
在一些实施例中，所述导向结构包括第一导向部和第二导向部，所述第一导向部与安装座101连接，所述第二导向部与伸缩件107连接，所述第一导向部和所述第二导向部相互配合。
在一些实施例中，第一导向部可以为安装座101上的凸起，第二导向部可以为伸缩件107上的凹槽，凹槽与凸起相互配合，以限定伸缩件107的运动方向，使伸缩件107能够在沿车身001宽度方向移动的同时旋转，从而带动车门002关闭和开启。
相对应地，第一导向部也可以为安装座101上的凹槽，第二导向部可以为伸缩件107上的凸起，凹槽与凸起相互配合，以限定伸缩件107的运动方向，使伸缩件107能够在沿车身001宽度方向往复移动的同时进行旋转，从而带动车门002关闭和开启。
此外，本公开一些实施例对第一导向部和第二导向部的结构不做限定，本领域技术人员可根据需要灵活设置，只需使第一导向部和第二导向部相互配合，从而能够实现伸缩件107在沿车身001宽度方向移动的同时进行旋转即可。
在一些实施例中，参照图3和图4，所述第一导向部为螺旋导向槽108，所述第二导向部为滚动体105，所述螺旋导向槽108与所述滚动体105相互配合。
在一些实施例中，滚动体105可以为球体；螺旋导向槽108可设置于伸缩件107的周侧，滚动体105设置于伸缩件107和安装座101之间，滚动体105与螺旋导向槽108的槽壁接触，以起到限定伸缩件107运动方向的作用，使得伸缩件107在沿着车身001宽度方向往复移动的同时发生旋转，以带动车门002开启或关闭。
在伸缩件107沿着车身001宽度方向往复移动时，滚动体105能够自由转动，从而减少滚动体105与伸缩件107之间的磨损和碰撞。
此时，驱动组件500还包括驱动机构，驱动机构为伸缩件107沿车身001宽度方向移动提供线性驱动力。驱动机构可以为任意一种能够提供线性驱动力的动力元件，比如液压缸、电动推杆或螺旋顶升机构等，本公开对此不做限定。
除此之外，可通过调节螺旋导向槽108的各项参数，以调整车门002的旋转角度。例如，当伸缩件107沿自身轴向运动150mm时，伸缩件107可借助螺旋导向槽108和滚动体105同时旋转90度，从而带动车门002旋转90度。
本公开一些实施例通过将车门铰链沿车身001宽度方向设置于车身001和车门002之间，相较于相关技术，减少了安装铰链结构所占用的平行于车门002的水平空间，从而解决了相关技术中铰链机构不适用于平行于车门002的水平方向设置空间不足的情况的问题；并且，相较于相关技术中的复杂齿轮设计，本公开一些实施例中的车门铰链采用滚动体105和螺旋导向槽108导向，结构设计简单，而且在车门002侧开旋转的过程中，不存在轮齿啮合所带来的振动和噪音。
在一些实施例中，参照图3和图4，安装座101设置有安装孔，所述安装孔用于容纳至少部分伸缩件107，所述安装孔的孔壁设置有滚动体105；伸缩件107的侧壁设置有螺旋导向槽108。
在一些实施例中，在安装座101上设置用于容纳伸缩件107的安装孔，可以提高整个铰链结构的紧凑性，有利用铰链结构的小型化设计，从而提高空间利用率。
在一些实施例中，参照图5和图6，所述车门铰链还包括保持架104；保持架104设置于所述安装孔内，保持架104设置有供伸缩件107穿过的通孔109，保持架104用于将滚动体105限制于伸缩件107和所述安装孔的孔壁之间。保持架104设置有供滚动体105至少部分嵌入的通孔109，通孔109的直径小于滚动体105的直径。所述安装孔的孔壁设置有供滚动体105至少部分嵌入的滚动槽110，滚动槽110与通孔109一一对应设置。
在一些实施例中，安装座101的内部设置有至少一组保持架104，保持架104上沿自身周向均匀设置有多个通孔109，每个通孔109与每个滚动槽110一一对应设置，每个滚动体105分别嵌入对应通孔109和滚动槽110所形成的容纳腔内，且滚动槽110的槽壁和滚动体105之间留有转动间隙。
保持架104与安装座101固定连接，具体可采用焊接的方式，从而将保持架104位置固定，避免保持架104在伸缩件107运动时发生移动，进而影响伸缩件107正常工作。
本公开一些实施例中，通过保持架104提高伸缩件107与安装座101之间的同轴度，从而提高伸缩件107的运动平稳性；保持架104上的通孔109的直径小于滚动体105的直径，以将滚动体105限制在通孔109内，当伸缩件107与滚动体105分离时，可以避免滚动体105从通孔109内掉出而影响伸缩件107后续正常工作。
除此之外，为了减少滚动体105与螺旋导向槽108的槽壁之间的磨损，使螺旋导向槽108的截面直径比滚动体105的直径大1mm～5mm，从而在滚动体105与螺旋导向槽108的槽壁之间预留滚动间隙。
在一些实施例中，参照图5和图6，保持架104为多个，多个保持架104沿伸缩件107的转动轴线方向间隔设置。
在一些实施例中，保持架104的数量可以为一个，也可为多个，通过提高增加保持架104的数量，可以提高伸缩件107运动的稳定性。
在一些实施例中，保持架104的数量为多个，多个保持架104沿伸缩件107的转动轴线方向等间隔设置，从而进一步提高伸缩件107运动的稳定性。
在一些实施例中，参照图3和图6，安装座101远离车身001的一端内径比伸缩件107的直径大0.1mm～0.5mm。
在一些实施例中，安装座101靠近车门002一端的内壁向内凸出形成环状，使得该端内径缩小并与伸缩件107的侧壁贴合，当伸缩件107部分向外旋出安装座101后，安装座101靠近车门002一端能够为伸缩件107提供支撑，以提高伸缩件107与安装座101的同轴度。
在本公开一些实施例中，安装座101向内凸出的部分沿自身轴向的尺寸为15mm，并且凸出部分与伸缩件107之间的间隙保持在0.1mm～0.5mm之间。
在一些实施例中，伸缩件107的侧壁沿自身周向设置有多条螺旋导向槽108，同一保持架104上的每个滚动体105分别嵌设于不同的螺旋导向槽108内。
例如，伸缩件107的侧壁上设置有多条螺旋导向槽108，多条螺旋导向槽108沿伸缩件107的周向均匀布设，通过增加螺旋导向槽108的数量，能够提高伸缩件107的运动稳定性。
在一些实施例中，参照图3和图6，所述驱动组件500还包括液压缸体102和液压杆103。液压缸体102设置于所述安装孔内。液压杆103与液压缸体102同轴设置，液压杆103与液压缸体102沿自身轴向滑动连接，且液压杆103能够绕自身轴线转动，液压杆103伸出液压缸体102的一端与伸缩件107固定连接。
在一些实施例中，液压缸体102同轴设置于安装座101内，液压缸体102靠近车身001的一端焊接有底座，底座上沿自身周向设置有多个螺栓孔，从而可以借助螺栓将液压缸体102固定于车身001上。
液压杆103与液压缸体102沿自身轴向滑动连接，并且液压杆103与液压缸体102转动连接，以使液压杆103能够绕自身轴线自由转动。液压杆103伸出液压缸体102的端部与伸缩件107固定连接，例如，可采用焊接或螺纹连接的方式，本公开对此不做限定。
当开启车门002时，液压缸体102驱动液压杆103伸出，液压杆103推动伸缩件107沿车身001宽度方向朝向远离车身001的一侧运动，并且，伸缩件107在螺旋导向槽108和滚动体105的作用下绕自身轴线旋转，直至车门002完全旋开。
当关闭车门002时，液压缸体102带动液压杆103收回，液压杆103拉动伸缩件107沿车身001宽度方向朝向靠近车身001的一侧运动，并且，伸缩件107在螺旋导向槽108和滚动体105的作用下绕自身轴线旋转，直至车门002完全关闭。
本公开一些实施例通过采用液压缸来驱动伸缩件107运动，相较于相关技术，不仅过程控制精度高，且在开关车门002过程中车门002能够在任意位置的稳定旋停。
在一些实施例中，参照3和图6，伸缩件107内设置有空腔，液压缸体102设置于所述空腔内。
例如，伸缩件107内同轴设置有空腔，当车门002处于完全关闭状态时，液压缸体102大部分置于空腔内。
在伸缩件107靠近车门002的一端设置有端头紧固件106，端头紧固件106将伸缩件107的端部开口封堵，端头紧固件106与伸缩件107可采用焊接的方式固定为一体件，也可采用卡扣结构固定为一体件，本公开对此不做限定，只需使端头紧固件106与伸缩件107固定为一体件且不发生相对移动即可。
液压杆103伸出液压缸体102的端部和端头紧固件106可采用焊接的方式固定连接；伸缩件107内的空腔的腔壁与液压缸体102之间留有滑动间隙。
当液压杆103靠近车门002的一端伸出液压缸体102时，液压杆103推动伸缩件107向远离车身001的一侧运动，此时，液压缸体102逐渐从空腔内漏出；而当液压杆103收缩时，液压杆103拉动伸缩件107向靠近车身001的一侧运动，此时，液压缸体102逐渐进入空腔内，直至液压杆103完全缩回液压缸体102内。
本公开一些实施例通过在伸缩件107内设置用于容纳液压缸体102的空腔，以缩小车门铰链的体积，从而减少了安装车门铰链所占用的空间，进一步提高了空间利用率。
在一些实施例中，参照图3、图5和图6，安装座101靠近车身001的一端设置有连接法兰111，连接法兰111用于与车身001连接，伸缩件107靠近所述连接法兰111的端面边缘设置有导向圆角。
例如，安装座101靠近车身001的一端焊接有连接法兰111，连接法兰111上沿自身周向均匀设置有多个螺栓孔，当安装车门铰链时，将螺栓一端穿过螺栓孔，从而借助螺栓将安装座101螺栓固定于车身001上。
伸缩件107靠近车身001的端面边缘设置导向圆角，从而在螺旋导向槽108的入口边缘形成过渡弧面，以便于滚动体105进入螺旋导向槽108内，避免滚动体105在进入螺旋导向槽108的过程中与螺旋导向槽108发生干涉。
在一些实施例中，参照图6，伸缩件107伸出安装座101的一端设置有连接板112，连接板112上设置有多个螺栓孔。
在一些实施例中，参照3和图4，伸缩件107伸出安装座101的一端焊接有连接板112，连接板112的四个角沿伸缩件107的径向凸出形成四个凸出部，且在每个凸出部上设置有螺栓孔；当安装车门铰链时，将螺栓的一端穿过螺栓孔并与车门002螺纹连接，从而将伸缩件107和车门002固定连接。
本公开一些实施例还提供了一种车门002，车门002包括上述车门铰链。
在一些实施例中，车门铰链采用螺栓固定于车门002上，并且车门铰链沿车身001宽度方向设置。
本公开一些实施例中，沿车身001宽度方向布置车门铰链，相较于相关技术，减少了安装铰链结构所占用的平行于车门002的水平空间，从而为在车门002内安装其他部件腾出空间，以解决相关技术中的铰链机构不适用于平行于车门002的水平方向设置空间不足的情况的问题。
参照图7，本公开一些实施例还提供了一种车辆600，车辆600包括上述车门002。
在一些实施例中，车辆600采用上述车门002，有利于节省平行于车门002的水平空间，从而为在车门002内安装其他部件腾出空间，以解决相关技术中的铰链机构不适用于平行于车门002的水平方向设置空间不足的情况的问题。
