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以及支撑组件30,所述立架组件20固定连接于所述底座10,所述支撑组件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,以使所述支撑组件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,以使所述支撑组件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。
所述支撑组件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。以使所述支撑组件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,所述支撑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,支撑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,这样支撑组件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,支撑组件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,支撑组件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,从而确定支撑组件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。
请一并参阅图5至图7,所述固定立杆22可以包括固定立杆主体220和折叠立杆部222。所述固定立杆主体220的一端固定安装于所述底座10,所述固定立杆主体220的另一端铰接于所述折叠立杆部222的一端,所述折叠立杆部222的另一端安装于所述移动立杆24,所述移动立杆24可沿所述折叠立杆部22的长度方向相对于所述折叠立杆部22移动。
在本实施例的所述标定支架100中,所述折叠立杆部22可相对于所述固定立杆主体220可枢转地转动。以使所述支撑组件30折叠,可较小所述标定支架100的高度,以方便装运。
所述移动立杆24可以包括内杆部240和外杆部242。所述内杆部240套设于所述外杆部242,所述内杆部240可沿所述折叠立杆部222的长度方向相对于所述外杆部242移动,所述外杆部242套设于所述折叠立杆部222,所述外杆部242可沿所述折叠立杆部222的长度相对于所述折叠立杆部222移动,所述驱动机构26用于驱动所述内杆部240相对于折叠立杆部222移动。通过内杆部240套设于外杆部242,并且外杆部242套设于折叠立杆部222,立架组件20的高度可减少为接近原来的三分之一,提高立架组件20的便携性,另外,只通过一个驱动机构26即可驱动外杆部242和内杆部240两个杆件相对于折叠立杆部222移动,立架组件20的重量基本不增加。
可以理解的是,一方面,根据实际情况,所述外杆部242还可以包括多个套杆,所述多个套杆中的一个套设于相邻的另一个。
在本实施例中,请参阅图11,所述折叠立杆部222设有第一滑槽2220和第一卡口2222,所述第一卡口2222与所述第一滑槽2220相连通,所述第一卡口2222的横截面尺寸小于所述第一滑槽2220的横截面尺寸。所述外杆部242的末端设有第一止挡部2420,所述第一止挡部2420的横截面尺寸大于所述外杆部242的横截面尺寸。所述第一止挡部2420套设于所述第一滑槽2220内,所述外杆部242套设于所述第一卡口2222。通过第一止挡部2420抵接于第一滑槽2220和第一卡口2222的交界处,可以防止外杆部242脱离折叠立杆部222。
在本实施例中,请复参阅图11,所述外杆部242设有第二滑槽2422和第二卡口2424,所述第二卡口2424与所述第二滑槽2422相连通,所述第二卡口2424的横截面尺寸小于所述第二滑槽2422的横截面尺寸。所述内杆部240设有第二止挡部2400,所述第二止挡部2400的横截面尺寸大于所述内杆部240的横截面尺寸。所述第二止挡部2400套设于所述第二滑槽2422内,所述内杆部240套设于所述第二卡口2424。过第二止挡部2400抵接于第二滑槽2422和第二卡口2424的交界处,可以防止内杆部240脱离外杆部242。
请一并参阅图8至图11,所述驱动机构26包括第一螺纹转动件260,第二螺纹转动件262,螺纹固定件264,第一斜齿轮266,第二斜齿轮268以及手轮269。
所述第一螺纹转动件260安装于所述折叠立杆部222,所述第一螺纹转动件260仅可绕中轴线O相对于所述折叠立杆部222转动,所述中轴线O基本平行于所述折叠立杆部222的长度方向。
所述第二螺纹转动件262设有绕所述中轴线O螺旋的第一螺纹结构(图未示)和第二螺纹结构(图未示),并且所述第一螺纹结构的螺旋方向和所述第二螺纹结构的螺旋方向一致,所述第二螺纹转动件262通过所述第一螺纹结构安装于所述第一螺纹转动件260,所述第二螺纹转动件262通过所述第二螺纹结构安装于所述螺纹固定件264,所述螺纹固定件264固定安装于所述内杆部240。
第一螺纹转动件260相对于折叠立杆部222转动,带动第二螺纹转动件262相对于第一螺纹转动件260和螺纹固定件264两者中的一个转动。也即,在一种情况中,在第一螺纹转动件260相对于折叠立杆部222转动时,第二螺纹转动件262相对于第一螺纹转动件260静止,此时,螺纹固定件264相对于第一螺纹转动件260和第二螺纹转动件262运动,在另一种情况中,在第一螺纹转动件260相对于折叠立杆部222转动时,第二螺纹转动件262相对于螺纹固定件264静止,此时,第二螺纹转动件262和螺纹固定件264皆相对于第一螺纹转动件260运动。在实际使用中,第一螺纹转动件260持续地相对于折叠立杆部222转动时,上述两种情况可能交替出现。通过第一螺纹转动件260、第二螺纹转动件262以及螺纹固定件264三者共同驱动内杆部240相对于折叠立杆部222移动,一方面,在内杆部240朝折叠立杆部222移动的过程中,由于第二螺纹转动件262也会朝折叠立杆部222运动,因此在第二螺纹转动件262设于杆件内不会限位内杆部240的行程,也不会突出内杆部240,从而使立架组件20更便于携带,另一方面,由于三者皆通过螺纹相连接,因此在内杆部240相对于折叠立杆部222移动至指定位置后,驱动机构26可以实现自锁。
所述第一螺纹转动件260包括轴颈部2600,第一螺杆部2602,第一限位部2604,所述第一轴颈部2600设于所述第一螺杆部2602的一端,所述第一限位部2604设于所述第一螺杆部2602的另一端,所述第一轴颈部2600的横皆面尺寸小于所述第一螺杆部2602的横截面尺寸,所述第一螺杆部2602的横截面尺寸小于所述第一限位部2604的横截面尺寸。
所述折叠立杆部222内设有安装隔板2224,所述安装隔板2224基本水平。所述轴颈部2600套设于所述安装隔板2224,由于第一螺纹转动件260、第二螺纹转动件262以及螺纹固定件264三者通过螺纹连接,因此第一螺杆部2602是与安装隔板2224相抵持的,从而使所述第一螺纹转动件260仅可绕所述中轴线O相对于所述折叠立杆部222转动。另外,安装隔板2224可对第二螺纹转动件260进行限位,当第一螺纹转动件260转动,以使第二螺纹转动件262与安装隔板2224相抵持时,第一螺纹转动件260继续转动,第二螺纹转动件 262将与第一螺纹转动件260保持静止,使螺纹固定件264朝折叠立杆部222移动,直到螺纹固定件264也抵持于安装隔板2224,此时第一螺纹转动件260不能继续转动。

所述第一螺杆部2602套设于所述第一螺孔2624内,所述第一限位部2604收容于所述第一容置槽2626内。通过在第一螺杆部2602的末端设置第一限位部2604,在第一螺纹转动件260转动的过程中,当第二螺纹转动件262可运动直到第一限位部2604抵持于第一螺孔2624与第一容置槽2626的交界处时,第一螺纹转动件260继续转动,第二螺纹转动件262将与第一螺纹转动件260保持静止,使螺纹固定件264背向折叠立杆部222移动。
在其他一些实施例中,所述螺纹固定件264套设于第二螺纹转动件262,所述第二螺纹结构设于所述第二螺纹转动件262内。

所述轴颈部2600的一端与所述第一螺杆部2602相连,所述第一斜齿轮266固定安装于所述轴颈部2600的另一端,所述第一斜齿轮266的旋转轴线与所述中轴线O相重合,所述第一斜齿轮266与所述第一螺杆部260可一同转动。

可以理解,安装座35可以为其他构造,例如不一定保持有一个缺口,可以在连接部36放入安装座35后,使用挡板等将缺口挡起来。也可以通过其他方式安装所述连接部36,例如,安装座35可以是一个完整的环状结构,无缺口以放入横梁,此时可以先将衡量组装完毕,然后再插入安装座35,再使用固定杆354对横梁进行旋紧固定。
可以理解,连接部36所压紧的安装座35的底面或侧面可能为圆弧形或其他不规则形状,此时同样可以使用所述固定杆354将连接部36压紧在这些面上,此时固定杆与这些面之间可能为线接触而非面接触,但不会影响压紧效果。

上述距离测量装置400用于测量支撑组件30距离地面的高度,并且优选地显示在距离测量装置400的液晶屏幕上。在一个实施例中,距离测量装置400是激光测距仪。底座10上设置有通孔120,用于使激光测距仪400的激光打到地面上,从而测量出支撑组件30距离地面的高度。
又例如,所述标定元件为图案板500(见图27),所述第一托件312和第二托件332共同托举所述图案板500,以防坠落。此外,所述第一导轨322上还可以安装有第一固定块510,所述第一固定块510可沿所述第一导轨322滑动,所述第二导轨342上安装有第二固定块520,所述第二固定块520可沿所述第二导轨342滑动,所述第一固定块510和第二固定块520分别位于所述图案板500的相对两侧,所述第一固定块510和第二固定块520协同夹紧所述图案板500。
