下面结合图1-图5详细描述根据本申请实施例的用于车辆的转向管柱10。
参照图1-图5所示，用于车辆的转向管柱10，包括：第一安装板1、调节板2、上管柱3、调节机构4和吸能机构5，其中：
调节板2沿第一方向可移动地与第一安装板1连接，第一安装板1和调节板2可通过直线轴承连接，上管柱3与调节板2固定，第一方向可以是上管柱3的轴向方向，上管柱3的上端连接车辆的方向盘，可通过移动调节板2，以改变上管柱3上端的位置，从而实现方向盘的位置调节。
调节机构4包括驱动部和第一调节部45，驱动部固定于第一安装板1，驱动部用于驱动第一调节部45沿第一方向移动，第一调节部45可带动调节板2在第一方向上相于第一安装板1移动，进而实现上管柱3和方向盘的位置调节。
吸能机构5包括吸能块51和吸能带52，吸能块51固定连接调节板2和第一调节部45，吸能块51内设有弯曲延伸的吸能槽5111，吸能槽5111具有在第一方向上弯曲的槽段，可选地，吸能槽5111包括半圆弧形槽段，或吸能槽5111包括正弦曲线形槽段。吸能带52的一端穿过吸能槽5111与第一调节部45固定，吸能带52的另一端沿第一方向延伸。
在调节上管柱3位置时，驱动部驱动第一调节部45沿第一方向移动，由于吸能块51、吸能带52均与第一调节部45固定连接，调节板2通过吸能块51与第一调节部45固定连接，上管柱3与调节板2固定连接，由此，第一调节部45可带动吸能块51、吸能带52、调节板2和上管柱3沿第一方向同步移动，以实现上管柱3和方向盘正常的高度调节，满足驾驶员的操纵舒适性需求。
在调节板2所受到的冲击力达到预设阈值时，吸能槽5111能够沿第一方向在吸能带52上移动，从而使吸能带52变形吸能，以在车辆发生碰撞时，上管柱3和调节板2可向远离驾驶员的方向移动，并通过吸能带52的变形吸收冲击能量，减轻驾驶员受伤程度。
具体地，当汽车发生碰撞时，驾驶员由于惯性撞击方向盘，方向盘、上管柱3和调节板2刚性连接，驾驶员撞击方向盘所产生的冲击力指向第一方向的一侧，即在第一方向上远离驾驶员的一侧，冲击力传递至调节板2时，调节板2和与其连接的吸能块51具有向第一方向一侧的运动趋势，而第一调节部45通过驱动部与第一安装板1固定，第一调节部45将通过吸能块51阻止调节板2的运动，从而导致吸能块51受到剪切力并发生断裂，调节板2与第一调节部45的刚性连接失效，调节板2带动吸能块51具有吸能槽5111的部分向第一方向的一侧移动，此时，由于吸能带52穿过吸能槽5111的一端与第一调节部45固定，吸能槽5111将沿第一方向在吸能带52上向第一方向的一侧移动，换言之，吸能槽5111由吸能带52的固定端向吸能带52的自由端移动，弯曲延伸的吸能槽5111在吸能带52上移动时，吸能带52将不断变形并吸收冲击力，从而使吸能带52起到缓冲和导向的作用， 以减轻驾驶员受伤程度。另外，在吸能块51断裂后，吸能带52还可以起到柔性连接调节板2与第一调节部45的作用，以防止上管柱3和调节板2向重力方向掉落，避免上管柱3和调节板2对驾驶员腿部造成二次伤害。
根据本申请实施例的用于车辆的转向管柱10，在发生碰撞时，上管柱3、调节板2和吸能槽5111能够向远离驾驶员的方向移动，吸能槽5111可使吸能带52变形以吸收冲击能量，同时吸能带52还可防止上管柱3和调节板2向下掉落，以减轻驾驶员受伤程度，提升转向管柱10的安全性能。
在本申请的一些实施例中，参照图1-图4所示，吸能块51包括本体部511和连接臂512，本体部511与调节板2固定，吸能槽5111设于本体部511，连接臂512与本体部511相连，连接臂512还与第一调节部45固定连接，连接臂512与本体部511的连接处设有削弱结构513，削弱结构513位于第一调节部45的朝向调节板2的一侧，也就是说，在第一方向上，削弱结构513的投影位于第一调节部45与调节板2之间，在调节板2所受到的冲击力达到预设阈值时，本体部511与连接臂512在削弱结构513处分离，且本体部511沿吸能带52移动，本体部511内的吸能槽5111在沿吸能带52移动时，吸能带52变形吸能，从而实现吸能效果。其中，预设阈值小于国标(GB11557防止汽车转向机构对驾驶员伤害的)规定中转向操纵装置作用在人体模块上的最大作用力，以在碰撞时保护驾驶员，且预设阈值大于驾驶员正常使用时对上管柱3的压力，以避免吸能块51在正常使用时损坏。可选地，预设阈值的取值范围为1KN～10KN。
在本申请的一些实施例中，参照图2-图4所示，本体部511的至少部分和连接臂512为一体成型件，本体部511和连接臂512可以是塑料结构件，例如PA(Polyamide，聚酰胺)塑料，连接臂512和吸能带52可通过紧固件9与第一调节部45固定连接，具体地，连接臂512上可设有第一安装孔5121，吸能带52的穿过吸能槽5111的一端可设有与第一安装孔5121对应的第二安装孔，可通过紧固件9穿过第一安装孔5121和第二安装孔后与第一调节部45固定，紧固件9可以是螺栓或铆钉。
在本申请的一些实施例中，参照图4所示，削弱结构513包括减薄槽，减薄槽可减薄连接臂512与本体部511连接处的厚度，以削弱连接臂512与本体部511的连接强度，可通过控制减薄槽的槽宽、槽深等参数，使调节板2在所受到的冲击力达到预设阈值时，本体部511与连接臂512在减薄槽处分离，调节板2在所受到的冲击力未达到预设阈值时，本体部511与连接臂512保持连接，减薄槽的长度方向垂直于第一方向且平行于调节板2，以保证减薄槽对连接臂512与本体部511的连接强度的削弱效果。
在本申请的另一些实施例中，削弱结构513包括多个削弱孔，削弱孔可以是通孔或盲孔，多个削弱孔可削弱连接臂512与本体部511的连接强度，可通过控制削弱孔的数量、 孔径大小和孔径深度等参数，使调节板2在所受到的冲击力达到预设阈值时，本体部511与连接臂512在多个削弱孔处分离，调节板2在所受到的冲击力未达到预设阈值时，本体部511与连接臂512保持连接，多个削弱孔的排布方向垂直于第一方向且平行于调节板2，以保证多个削弱孔对连接臂512与本体部511的连接强度的削弱效果。
在本申请的一些实施例中，调节板2设有安装凹槽，安装凹槽的开口可朝向第一调节部45，本体部511的至少部分设于安装凹槽内，安装凹槽可用于提升本体部511与调节板2的连接强度，在本体部511沿吸能带52移动时，安装凹槽的至少一个侧壁可止抵于第一调节部45，以防止本体部511与调节板2分离。
在本申请的一些实施例中，参照图2-图5所示，本体部511包括第一分部5112和第二分部5113，吸能槽5111设于第一分部5112，连接臂512可与第一分部5112连接，吸能槽5111具有设于第一分部5112的侧面的侧进出口5114，第二分部5113适于与第一分部5112固定连接以封堵侧进出口5114，其中，第一分部5112的侧面垂直于吸能槽5111，由此，吸能带52可由侧进出口5114装入弯曲延伸的吸能槽5111内，再将第二分部5113与第一分部5112固定组合，以使第二分部5113封堵侧进出口5114，从而有利于吸能带52与本体部511的装配。
在本申请的一些实施例中，第一分部5112和第二分部5113中的一个设有定位销5115，另一个设有适于与定位销5115配合的定位孔5116，以便于第一分部5112和第二分部5113在固定连接时的定位，其中，定位销5115和定位孔5116的数量可以是一对或多对。
在本申请的一个实施例中，参照图4所示，第一分部5112具有侧进出口5114的侧面上设有两个间隔设置的定位销5115，第二分部5113上对应设有两个定位孔5116，每个定位孔5116对应定位配合一个定位销5115。
在本申请的另一个实施例中(图中未示出)，第二分部5113封堵侧进出口5114的侧面上设有两个定位销5115，第一分部5112对应设有两个定位孔5116，每个定位销5115对应定位配合一个定位孔5116。
在本申请的一些实施例中，参照图2-图4所示，本体部511可通过紧固件9与调节板2固定连接，具体地，第一分部5112设有第一安装台5117，第一安装台5117适于搭接在安装凹槽的外沿，第一安装台5117上设有至少一个第三安装孔5118，可通过紧固件9穿过第三安装孔5118与调节板2固定，第二分部5113设有第二安装台5119，第一安装台5117和第二安装台5119分别位于本体部511相对的两侧，第二安装台5119适于搭接在安装凹槽的外沿，第二安装台5119上设有至少一个第四安装孔5120，可通过紧固件9穿过第四安装孔5120与调节板2固定，紧固件9可以是螺栓或铆钉。
可以理解的是，在车辆发生碰撞后，吸能机构5损坏，吸能机构5分别与第一调节部 45和调节板2通过紧固件9实现可拆卸地连接，在车辆发生较轻的碰撞后，仅更换吸能块51和吸能带52即可完成对转向管柱10的维修，且吸能块51和吸能带52的加工工艺简单、制造成本较低、拆装方便快捷，从而有利于降低转向管柱10的维修成本。
在本申请的一些实施例中，参照图1所示，转向管柱10还包括第二安装板6，第二安装板6适于与车辆的车身固定，例如第二安装板6固定于车辆的仪表横梁，第一安装板1沿第一方向可移动地与第二安装板6连接，第一安装板1和第二安装板6可通过直线轴承连接，调节机构4还包括第二丝杠46，第二丝杠46与第二安装板6固定，第一调节部45为螺母，驱动部包括驱动电机41、驱动盒和第一丝杠44，驱动电机41通过驱动盒与第一安装板1固定，驱动盒与驱动电机41、第二丝杠46和第一丝杠44传动连接，驱动电机41通过驱动盒和第一丝杠44驱动第一调节部45沿第一方向移动，驱动电机41还驱动驱动盒在第二丝杠46上沿第一方向移动，由此，可以提升上管柱3位置的调节效率，并减少转向管柱10的占用空间。
具体地，驱动盒内设置有主动齿轮、第一被动齿轮42和第二被动齿轮43，第一被动齿轮42和第二被动齿轮43均与主动齿轮传动连接，驱动电机41可驱动主动齿轮转动，以通过主动齿轮驱动第一被动齿轮42和第二被动齿轮43转动。可选地，驱动电机41和主动齿轮之间还设置行星传动模组，电机输出的动力经行星传动模组减速增扭后驱动主动齿轮转动，同时，驱动盒内还设有惰轮，主动齿轮、第一被动齿轮42和第二被动齿轮43均与惰轮啮合，主动齿轮通过惰轮驱动第一被动齿轮42和第二被动齿轮43转动，惰轮可增大主动齿轮、第一被动齿轮42和第二被动齿轮43之间的轴线间距，以便于第一丝杠44、第二丝杠46和驱动电机41的布置。
第一丝杠44穿设驱动盒和第一被动齿轮42，第一被动齿轮42与第一丝杆限位配合，第一被动齿轮42可带动第一丝杠44转动，在第一丝杠44转动时，第一丝杠44可驱动第一调节部45在第一方向上移动。
第二丝杠46穿设驱动盒和第二被动齿轮43，第二被动齿轮43与第二丝杠46螺纹配合，第二被动齿轮43转动时，可带动驱动盒在第二丝杠46上沿第一方向移动，且驱动盒的移动方向和第一调节部45的移动方向相同，同时，驱动电机41和第一安装板1均与驱动盒连，驱动电机41和第一安装板1均跟随驱动盒同步移动，也就是说，驱动部可驱动调节板2和第一安装板1沿第一方向同步移动，从而在有限的空间内，可增大上管柱3在第一方向的可调节范围，并提升上管柱3的调节效率。
在本申请的一些实施例中，吸能带52为钢带，也就是说，吸能带52为钢材质件，钢带成本较低、便于加工、变形吸能效果好，可根据吸能需求调整吸能槽5111尺寸以及对应设置钢带的长度、厚度、刚度等参数，以满足不同车型溃缩力及溃缩距离的设计要求。
参照图4和图5所示，吸能块51内设有弯曲延伸的吸能槽5111，吸能槽5111沿类似“L型”的走向，吸能带52包括固定段521、安装段522和自由段523，固定段521通过安装段522与自由段523连接，固定段521位于吸能槽5111外侧且适于与第一调节部45连接，安装段522位于吸能槽5111内且与吸能槽5111随形，自由段523位于安装槽外且沿第一方向延伸，在发生碰撞时，方向盘、上管柱3、调节板2和与吸能块51具有吸能槽5111的部分同步移动，吸能槽5111在自由段523上滑移，自由段523在吸能槽5111内变形吸能，吸能带52可对吸能槽5111的滑移起到缓冲和导向作用，同时又能避免方向盘及上管柱3从仪表横梁内滑落冲击驾驶员的身体。
根据本申请另一方面实施例的车辆，包括上述实施例的转向管柱10。

尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型。
