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,图2和图3,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。
在本实施例的所述标定支架100中,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可枢转地转动。以使所述横梁组件30折叠,可减小所述标定支架100的体积,以方便装运。
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。
可选的,所述横梁组件安装在所述移动立杆的顶面。这使得相比起传统的标定架,横梁组件的重心更加接近立杆重心,可以增加标定架的稳定性,并且可以使用面积更小的底座。
可选的,第一横梁部32和第二横梁部34可相对于所述连接部36相向地转动,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。
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。
请一并参阅图4和图5,所述立架组件20可以包括固定立杆22,移动立杆24和驱动机构26,所述移动立杆24套设于所述固定立杆22内,所述移动立杆24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,所述驱动机构26安装于所述固定立杆22,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。使用移动立杆24与固定立杆22套设连接的方式,立架组件20的高度可以减为接近原来的一半,配合横杆组件30的折叠,可以使立架组件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,也可以视需要将固定立杆作为内杆,移动立杆作为外杆,驱动机构26安装于所述固定立杆22,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。
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。
所述固定立杆22和所述移动立杆24也可以分别为截面为圆形的圆柱形管材,此时可以通过导向机构防止所述固定立杆22相对于所述移动立杆24转动,用于引导所述移动立杆24稳定地相对于所述固定立杆22移动,或者在标定支架100的其他部件处增设检测及调整固定立杆22相对于移动立杆24发生除长度方向运动的机构。一种简便的导向机构是导轨及与之配合的滑块装置,可以在固定立杆22和所述移动立杆24相互接触的表面处,在该两者之一上设置导 轨,在另一者上设置例如凸块、塑料胶条、滚轮、滚珠、齿轮等的滑块装置,此时滑块装置将被限制在导轨上运动,也能确保两个立杆之间只发生沿长度方向的相对运动。导轨可以是附加设置在立杆管壁上的凹槽、线状凸起、齿条等,也可以是立杆管壁自身形成的凹槽、线状凸起、两条线状凸起之间形成的凹槽等,即立杆使用异形管壁,管壁本身形状就带有凹槽、线状凸起等可以作为导轨使用的部分。同样,滑块装置可以是附加设置在立杆管壁上的额外部件,也可以是依靠立杆管壁自身形成的凸起结构,而无需在立杆管壁处设置额外部件。此外,齿条等通过啮合来实现传动的机构,本身也有导向作用,本说明书也将其归入导轨范畴内。如下面实施例所描述的齿轮与齿条的传动机构,也能实现导向效果。可选的,齿条可以设置在凹槽导轨内。
可以理解的是,导轨与滑块装置的设置位置可以互换,可以导轨设置在移动立杆上、滑块装置设置在固定立杆上,也可以互换。
可以理解的是,导向机构并不限于截面为圆形的固定立杆22和移动立杆24,其他截面形状的固定立杆22和移动立杆24上也可以使用导向机构来增强导向作用,并且获得更加稳定或摩擦力更小的相对运动。对于非圆形的截面形状,也可以不使用导轨,仅使用直线运动装置来获得更稳定或摩擦力更小的相对运动,此时非圆形的外部立杆本身就起到导向作用。
