Description

一种标定支架
本申请要求于2020年3月27日提交中国专利局、申请号为202010230678.4、申请名称为“一种标定支架”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及车辆维修及设备标定技术领域，特别涉及一种标定支架。
背景技术
先进驾驶辅助系统(Advanced Driver Assistant System)，简称ADAS，是利用安装于车上的各式各样的传感器，在第一时间收集车内外的环境数据，进行静、动态物体的辨识、侦测与追踪等技术上的处理，从而能够让驾驶者在最快的时间察觉可能发生的危险，以引起注意和提高安全性的主动安全技术。ADAS采用的传感器主要有摄像头、雷达、激光和超声波等，可以探测光、热、压力或其它用于监测汽车状态的变量，通常位于车辆的前后保险杠、侧视镜、驾驶杆内部或者挡风玻璃上。在车辆使用过程中，震动、碰撞、环境温湿度等均会使上述传感器的物理安装状态发生改变，故需要不定期进行校准或标定。
对上述传感器进行校准或标定时，通常会在标定支架的横梁上挂载标定元件，以对车辆上的传感器进行校准或标定。然而，目前大多数的标定支架及横梁的体积比较大、占地面积也大，组装复杂，且难以搬迁。

除非另有定义，本说明书所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是用于限制本发明。本说明书所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。
此外，下面所描述的本发明不同实施例中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
请一并参阅图1和图2，本发明其中一实施例提供的标定支架100，包括底座10，立架组件20以及横梁组件30，所述立架组件20固定连接于所述底座10，所述横梁组件30包括第一横梁部32，第二横梁部34和连接部36，所述连接部36安装于所述立架组件20，所述连接部36的一端铰接于所述第一横梁部32，所述连接部36的另一端铰接于所述第二横梁部34。
所述横梁组件30包括至少一个关节机构38，所述关节机构38连接于所述第一横梁部32与所述连接部36之间，或者连接于所述第二横梁部34与所 述连接部36之间。
所述关节机构38包括第一固定件381、第二固定件382，以及连接在所述第一固定件381和第二固定件382之间的旋转连接块383。所述旋转连接块383的一端可转动地固定于所述第一固定件381，所述第二固定件382的一端可转动地固定于所述旋转连接块383的另一端，以使所述第一横梁部32或所述第二横梁部34可相对于所述连接部36旋转并折叠；其中，所述第一横梁部32的旋转方向与所述第二横梁部34的旋转方向相同。所述第一横梁部32和所述第二横梁部34可分别相对于所述连接部36相向转动，以使所述横梁组件30折叠，所述第一横梁部32和所述第二横梁部34也可分别相对于所述连接部36背向转动，以使所述横梁组件30展开。
所述“安装”包括焊接安装等固定安装，也包括可拆卸安装。
所述横梁组件30可用于挂载标定元件，例如，多线激光器200、标定标靶、雷达反射或吸收装置等，以对车载辅助驾驶系统进行标定。
所述第一横梁部32，所述第二横梁部34和所述连接部36构成横梁。
在本实施例中，第一横梁部32和第二横梁部34可相对于所述连接部36的相背两侧相向地转动，即第一横梁部32与第二横梁部34的旋转方向相同，同为顺时针枢转，或同为逆时针枢转。此种情况中，第一横梁部32和第二横梁部34在折叠状态时位于连接部36的相向两侧上。例如，它们可以一个向上折叠一个向下折叠，或者一个向前折叠一个向后折叠，折叠后的第一横梁部32和第二横梁部34与连接部36紧贴放置，并且通过可松开的固定装置固定在连接部36上，可减小所述标定支架100的体积，以方便装运。当第一横梁部32和第二横梁部34一个向上折叠一个向下折叠，或者一个向前折叠一个向后折叠时，连接部36的长度可以相对较短。同样地，为了进一步减小标定支架100所占用空间，横梁组件30可以从立架组件20上取下来，携带到需要使用的地方后，再安装在立架组件20上。
可选的，第一横梁部32和第二横梁部34也可相对于所述连接部36的同一侧相向地转动，即第一横梁部32与第二横梁部34的旋转方向相反，若二者中的一个为顺时针枢转，则二者中的另一个为逆时针枢转。在此种情况下，第一横梁部32和第二横梁部34在折叠状态时位于连接部36的同一侧上。例如，它们可以一起向下折叠，也可以一起向上、向前、向后折叠。可选的，当第一横梁部32和第二横梁部34向下折叠时，连接部36的长度可以相对较短，并且第一横梁部32和第二横梁部34呈下垂状态，这样横梁组件30可以无需从立架组件20上取下来，标定支架100占用空间也会显著减小，可以方便使用交通工具携带。当第一横梁部32和第二横梁部34向上、向前、向后折叠时，可以设置使横梁转动的装置，从而使第一横梁部32和第二横梁部34的最终折叠方向向下，也可以使得这两者呈下垂状态；或者可以使连接部36的长度相对较长，折叠后得第一横梁部32和第二横梁部34可以与连接部36紧贴放置，并且通过可松开的固定装置固定在连接部36上。在后一种情况中，为了进一 步减小标定支架100所占用空间，横梁组件30可以从立架组件20上取下来，携带到需要使用的地方后，再安装在立架组件20上。
本领域技术人员可以理解，横梁组件30的折叠方式不限于上述方式。例如，横梁可以折叠为两端，此时没有连接部36；横梁也可以折为四段或更多段。但优选为三段，因为这使得横梁中段无断口，那么可以在中段处只使用一个紧固部件，就可以将横梁稳定且平衡地固定在立杆上。
请参阅图3，本实施例提供的关节机构38数量为两个，一个所述关节机构38可滑动地连接于所述第一横梁部32与所述连接部36之间，另一个所述关节机构38可滑动地连接于所述第二横梁部34与所述连接部36之间。在一些实施例中，所述关节机构38可滑动地连接于所述第一横梁部32、第二横梁部34和/或连接部36的壁管之内。在一些实施例中，所述关节机构38可滑动地连接于所述第一横梁部32、第二横梁部34和/或连接部36的壁管之外。

在本实施例中，所述旋转连接块383呈Z型，所述旋转连接块383的高度小于或等于所述第一固定块381的高度，且所述旋转连接块383的高度小于或等于所述第二固定块382的高度。
所述旋转连接块383设置成Z型，增大所述第一横梁部32或所述第二横梁部34的旋转角度，使所述第一横梁部32或第二横梁部34可绕所述连接部36的旋转角度范围为0-360度，同时在所述第一横梁部32或第二横梁部34 绕所述连接部36旋转时，旋转平稳。
所述第一销轴384的长度小于或等于所述第一固定块381的高度，所述第二销轴385的长度小于或等于所述第二固定块382的高度。

可以理解的是，所述旋转连接块383也可以为“工”型，所述第一凸起3811和所述第二凸起3821分别位于所述旋转连接块383的两个开口内。
当所述第一横梁部32和所述连接部36上分别设有收容所述关节机构38的收容腔时，两个收容腔内分别设有限位装置，以限制关节机构38的行程，所述关节机构38可滑动地连接于所述第一横梁部32与所述连接部36之间，所述连接部36的收容腔的长度与所述第一横梁部32的收容腔的长度之和需大于或等于所述关节机构38完全展开的长度，以使所述关节机构38可完全收容于所述第一横梁部32的收容腔和所述连接部36的收容腔。
同样，当所述第二横梁部34和所述连接部36上分别设有收容所述关节机构38的收容腔时，两个收容腔内分别设有限位装置，以限制关节机构38的行程，所述关节机构38可滑动地连接于所述第二横梁部34与所述连接部36之间，所述连接部36的收容腔的长度与所述第二横梁部34的收容腔的长度之和需大于或等于所述关节机构38完全展开的长度，以使所述关节机构38可完全收容于所述第二横梁部34的收容腔和所述连接部36的收容腔。
所述关节机构38完全展开的长度的是指所述第一固定件381与所述第二固定件382位于同一平面时，所述关节机构38所展示状态的整体长度。
当只有所述连接部36上设有收容所述关节机构38的收容腔时，所述第二固定件382完全固定于所述第一横梁部32或第二横梁部34的内壁，或者所述第二固定件382与所述第一横梁部32或第二横梁部34内壁一体成型，所述关节机构38可滑动地收容于所述连接部36的收容腔，且所述关节机构38可完全收容于所述连接部36的收容腔。

请参阅图5，当所述第一固定件381和所述第二固定件382位于同一平面时，用力将所述第一横梁部32或第二横梁部34朝所述连接部36推，使所述关节机构38完全收容于所述连接部36和所述第一横梁部32或第二横梁部34之间，所述连接部36和所述第一横梁部32或第二横梁部34抵接，使得所述第一横梁部32或第二横梁部34相对于所述连接部36稳定地处于展开状态。

可以理解的是，所述第一固定件381也可以不收容于所述连接部36内部，所述第二固定件382也可以不收容于所述第一横梁部32或所述第二横梁部34内部，例如，所述第一固定件381可滑动地套设于所述连接部36的外壁，所述第二固定件382可滑动地套设于所述第一横梁部32的外壁或所述第二横梁部34的外壁，在所述横梁组件30展开或折叠时，通过一个锁紧件进一步固定所述横梁组件30，以使所述第一横梁部32或第二横梁部34相对于所述连接部36稳定地处于展开或折叠状态。
可以理解，所述第一固定件381和所述第二固定件382也可以不通过所述旋转连接块383连接在一起，两者并不连接，但第一横梁部32或第二横梁部34与连接部36的外壁通过一个额外的转轴连接在一起，这也能实现第一横梁部32或第二横梁部34与连接部36之间可枢转的连接。
请参阅图7，为了增加所述第一横梁部32和第二横梁部34分别与连接部36的卡合力度，以使所述第一横梁部32和第二横梁部34可挂载重量更大的标定元件，所述标定支架100还可以包括搭扣结构40，一个所述搭扣结构40连接于第一横梁部32与连接部36之间，另一个所述搭扣结构40连接于第二横梁部34与连接部36之间。

使用移动立杆24与固定立杆22套设连接的方式，所述立架组件20的高度可以减为接近原来的一半，配合所述横梁组件30的折叠，可以使所述立架组件20非常适合放置在汽车等交通工具的后尾箱内携带。
可以理解的是，也可以视需要将所述固定立杆作为内杆，所述移动立杆作为外杆。
可选的，所述固定立杆22和所述移动立杆24分别为方通，所述移动立杆24紧密地套设于所述固定立杆22内，可使得所述移动立杆24仅能沿所述固定立杆22的长度方向相对于所述固定立杆22移动，并且可防止所述移动立杆24相对于所述固定立杆22朝其它方向运动。这种构造对标定支架100实现可折叠非常重要，因为在标定过程中，通常需要利用标定支架100各部件之间固定的相对位置关系，例如，有可能在固定立杆22的外表面固定一个激光器，使用该激光器来定位车辆中心轴线，从而确定横梁组件30上所携带标靶与车辆之间的相对位置。因此，如果各部件之间的相对位置有些许变化，都会使标定精度受到影响，或者需要增设额外的微调机构来弥补。如果各部件之间的相对位置变化较大，还有可能导致增设的额外微调机构失效。因此，在套叠方式下，移动立杆24与固定立杆22之间除了沿长度方向之外的相对运动，例如相对转动，是需要排除的。一个简便的方法是移动立杆24与固定立杆22同为方通，这样能确保两者之间只发生沿长度方向的相对运动。
可以理解的是，在一些其它实施例中，所述固定立杆22和所述移动立杆24也可为其它形状的管材，例如，截面为相互配合的多边形的管材，可使得所述移动立杆24仅能沿所述固定立杆22的长度方向相对于所述固定立杆22移动，并且可防止所述移动立杆24相对于所述固定立杆22朝其它方向运动。此处“相互配合”不一定要求固定立杆22与移动立杆24的截面必须相同，例如设置在外的固定立杆22的截面可以为六边形，设置在内的移动立杆24的截面可以为与该六边形相接的四边形，同样可以实现使得移动立杆24仅能沿固定立杆22的长度方向相对于固定立杆22移动的效果。固定立杆22和所述移动立杆24的截面也可以为相互配合的椭圆形的圆柱形管材，椭圆形的截面同样可以在一定程度上限制两者之间的相对转动。
在一些实施例中，可在所述固定立杆22上安装一个驱动机构(图未标示)，用于驱动所述移动立杆24沿所述固定立杆22的长度方向相对于所述固定立杆22移动。所述驱动机构可为齿轮箱传动、丝杠传动、同步带传动等，只要能驱动所述移动立杆24相对于所述固定立杆22移动即可，例如专利申请号CN201911067124.0中所描述的驱动机构。
在一些实施例中，所述移动立杆24设置有限位部，所述限位部位于所述固定立杆22内，所述固定立杆22的内壁设置凸缘，所述凸缘靠近所述固定立杆22的顶端，当所述移动立杆24相对于所述固定立杆22移动至所述限位部抵触所述凸缘时，所述移动立杆24停止移动，可防止所述移动立杆24脱离所述固定立杆22。
在一些实施例中，在所述固定立杆22上安装有紧固机构，用于将所述移动立杆24固定于需要的位置，例如，所述紧固机构可为螺钉，所述螺钉穿过所述固定立杆22，并且与所述固定立杆22螺纹配合，当所述移动立杆24相对于所述固定立杆22移动至需要的位置时，转动所述螺钉，使其抵紧所述移动立杆24，使所述移动立杆24固定于需要的位置。反方向转动所述螺钉，使其脱离所述移动立杆24，所述移动立杆24便可沿所述固定立杆22的长度方向相对于所述固定立杆22移动。
所述连接部36可通过一个紧固件可拆卸地安装于所述移动立杆24或所述固定立杆22，例如，所述紧固件可为U型角码，所述U型角码安装于所述移动立杆24或所述固定立杆22，所述连接部36固定于所述U型角码的U型槽内。
在所述连接部36安装于所述移动立杆24时，所述横梁组件30可由所述移动立杆24带动沿所述固定立杆22的长度方向相对于所述固定立杆22移动。
请复参阅图1，所述底座10包括底座本体12，滚轮14、高度调节件16和拉环18。
所述底座本体12为三角爪状，包括三个爪部，三个所述爪部分别沿三个不同的方向延伸。所述底座本体12可由金属材料制得。
所述滚轮14安装于所述底座本体12的底表面，所述滚轮14的数量可以 为三个，每个所述滚轮14安装于对应的一个所述爪部的末端，用于方便移动所述底座本体12。在本实施例中，所述滚轮14为万向移动滚轮，使得所述底座本体12可以前后左右任意移动。
所述高度调节件16安装于所述底座本体12，用于调节所述底座本体12的高度。在本实施例中，所述高度调节件16为调节旋钮，数量为三个，旋钮下方包含至少一段螺旋杆，该螺旋杆与底座处通孔的螺纹相配合，可以实现高度调节。每个所述高度调节件16安装于对应的一个所述爪部，并且靠近对应的一个所述滚轮14，三个所述高度调节件16呈正三角形分布。
所述拉环18可以安装于其中的一个所述爪部的上表面，用于方便拉动所述标定支架100。
可以理解的是，在一些其它实施例中，所述底座本体12的形状可以根据实际需求变化，而不限于为三角爪状，例如所述底座本体12可为矩形或圆形；所述滚轮14和所述高度调节件16的数量可以分别根据实际需求增减，例如，对于三角爪状的底座本体12，高度调节件可以为两个，再配合一个固定高度的支脚以调节底座本体12的角度。
本发明实施例提供的一种标定支架，通过关节机构38，可使所述第一横32梁部和所述第二横梁部34可分别相对于所述连接部36转动，以使所述横梁组件30折叠，且所述第一横梁部32的旋转方向与所述第二横梁部34的旋转方向可以相同，在所述横梁组件30折叠后，所述第一横梁部32和所述第二横梁部34可分别位于所述连接部36的相对两侧，使所述横梁组件30的折叠不受横梁长度的影响，同时所述横梁组件30可拆卸地安装于所述立架组件20，从而减小所述标定支架100的体积，以方便装运。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；在本发明的思路下，以上实施例或者不同实施例中的技术特征之间也可以进行组合，步骤可以以任意顺序实现，并存在如上所述的本发明的不同方面的许多其它变化，为了简明，它们没有在细节中提供；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
