Description

隔振垫和可移动平台 技术领域
本申请涉及可移动平台技术领域,特别涉及一种隔振垫和可移动平台。
背景技术
目前,多旋翼无人机由于其稳定性好,操纵简单,能够原地垂直起降,场地要求简单,隐蔽性好,在军事、民用、科学领域均得到了广泛的应用和发展。无人机在飞行过程中,由于旋翼振动,气流扰动等因素产生的宽频振动激励经过机身传递到镜头,会对镜头的成像质量产生严重影响,因此需要采取措施来对镜头进行主动增稳。在相关技术中,通常采用云台来实现对镜头的增稳。然而云台安装在无人机上时,无人机所产生的振动激励也会传递到云台,造成对在云台上的镜头的增稳效果欠佳。

请参阅图1和图2,本申请实施方式的一种隔振垫100,用于连接可移动平台200主体12和云台300,隔振垫100包括第一连接部14和第二连接部16。
第一连接部14沿隔振垫100周向设有至少两个第一连接件18,第一连接件18用于与云台300配合连接以实现隔振垫100与云台300的安装。第二连接部16沿隔振垫100周向设有至少两个第二连接件20,第二连接件20用于与主体12配合连接以实现隔振垫100与主体12的安装。其中,第一连接件18与第二连接件20的其中一个包括安装孔22,另一个包括卡块24。
上述隔振垫100通过沿周向设置的第一连接件18实现与云台300的安装,及通过第二连接件20实现与主体12的安装,主体12上的振动激励可以经由第二连接件20和第一连接件18进行分散隔离,有效地减少了从主体12传递至云台300的振动激励,提升了云台300的增稳效果。
具体地,可移动平台200包括无人机、无人车、无人船、机器人或拍摄稳定器。可移动平台200在移动时,通常会产生振动,例如,当可移动平台200为多旋翼无人机时,无人机的旋翼旋转时,会产生振动激励。若该振动激励不经过滤就直接传递到云台300上,会使得云台300的振动也随之增大,会减弱云台300的增稳效果。在可移动平台200主体12和云台300之间连接有隔振垫100,使得可移动平台200的振动激励尽可能少地传递至云台300,提升了云台300对负载的增稳效果。
在图1所示的实施方式中,第一连接件18包括安装孔22,第二连接件20包括卡块24,位于最外侧的云台300电机壳上设有卡件26(见图3),卡件26可穿设安装孔22,且卡件26的顶部可以卡设在第一连接部14的表面,可以实现隔振件与云台300过盈配合连接。在一个实施方式中,卡件26可以呈T型,如此隔振垫100与云台300的安装效果好,结构牢固。
主体12上可设有卡孔(图未示),卡块24可以穿设卡孔,且卡块24的顶部可以卡设在主体12的表面,可以实现隔振垫100与主体12的安装。
在某些实施方式中,第一连接件18与对应的一个第二连接件20沿隔振垫100的径向排列。如此,隔振垫100与主体12和云台300的连接强度较好。
具体地,沿隔振垫100的径向排列的第一连接件18和第二连接件20,两者之间的距离较短,使得第一连接件18与云台300的安装点和第二连接件20与主体12的安装点之间的距离也较短,在振动传递时,可以减少两个安装点之间的振幅,避免第一连接件18与云台300之间发生意外脱落,及避免第二连接件20与主体12之间发生意外脱落,保证了隔振垫100与主体12和云台300的连接强度。
在图示的实施方式中,第一连接件18的数量是三个,三个第一连接件18沿隔振垫100周向均匀间隔设置,第二连接件20的数量是三个,三个第二连接件20与三个第一连接件18一一对应,每个第一连接件18与对应的一个第二连接件20沿隔振垫100径向排列。可以理解,在其它实施方式中,第一连接 件18的数量不限于三个,还可以是二个或多于三个,第二连接件20的数量不限于三个,还可以是二个或多于三个。
在某些实施方式中,安装孔22呈跑道型。如此,安装孔22可以增加连接强度。
具体地,在图示的实施方式中,第一连接件18包括安装孔22,第二连接件20包括卡块24。云台300可包括卡件26,卡件26的顶部可以设置有卡勾28(见图5),卡件26穿设安装孔22。卡勾28可以沿安装孔22的周缘卡在第一连接件18。相较于圆形孔,呈跑道型的安装孔22的周缘长度较大,可允许卡勾28的尺寸适当增大,卡勾28卡在第一连接件18的部位也较多,可以提升云台300与第一连接件18的连接强度。
在某些实施方式中,至少两个第一连接件18沿隔振垫100周向排列呈环形,至少两个第二连接件20沿隔振垫100周向排列呈环形,至少两个第一连接件18位于至少两个第二连接件20所构成的环形内。如此,可以使隔振垫100分别与云台300和主体12连接更牢固。
具体地,在图示的实施方式中,第一连接件18和第二连接件20的数量均为三个,三个第一连接件18和三个第二连接件20均沿隔振垫100周向排列呈形环形。呈环形排列的连接件,可以将隔振垫100与主体12和云台300的安装点分布也呈环形,形成内环与外环的连接分布,整体上提升隔振垫100分别与云台300和主体12的连接强度,使三者连接更牢固。
在某些实施方式中,至少两个第一连接件18排列所构成的环形与至少两个第二连接件20排列所构成的环形同心设置。如此,可以避免或减少因振动传递而造成期望外的隔振垫100振动。
具体地,至少两个第一连接件18排列所构成的环形为内环,至少两个第二连接件20排列所构成的环形为外环,内环与外环同心设置。在主体12上的振动传递至隔振垫100时,由于内环与外环同心设置,使得振动在隔振垫100上各个方向的传递趋于一致,可以避免或减少因振动在各个方向传递差异而造成期望外的隔振垫100振动。
在某些实施方式中,卡块24呈T型。如此,卡块24的卡设效果好。
具体地,在图示的实施方式中,第一连接件18包括安装孔22,第二连接件20包括卡块24。请参图1,卡块24可包括柱状部30和卡部32,柱状部30连接卡部32,卡部32相对于柱状部30的周缘沿180度具有两个凸出部位,安装主体12和隔振垫100时,卡部32在穿过主体12上的卡孔时发生变形,卡部32穿过卡孔后恢复形状,柱状部30穿设在卡孔内,卡部32的凸出部位可以沿180度将主体12上围成卡孔的周缘部位压紧。
在一个实施方式中,隔振垫100在制造出来时,卡部32的末端预留有三个细长的镊子状的辐条34。在安装隔振垫100与主体12时,三个辐条34可穿入主体12上的卡孔,并拉扯辐条34,使辐条34根部(即卡部32)卡住主体12进行限位,之后,可以将辐条34剪断去除。隔振垫100的穿孔安装方式,比较简单牢靠,且额外增加安装结构尺寸和重量均较小。
在某些实施方式中,第二连接部16呈环形,沿隔振垫100周向连接在第一连接部14的边缘。如此,可以形成一类似于碗状的隔振垫100,隔振效果好。
具体地,呈环形的第二连接部16连接主体12,主体12上的振动传递至第二连接部16时,由环形的第二连接部16进行分散,避免振动过于集中而造成局部振动过大而降低隔振效果。
在某些实施方式中,请参图1和图2,卡块24的底部设有第一夹持面36,卡块24的顶部设有与第一夹持面36相对的第二夹持面38,第一夹持面36与第二夹持面38用于共同夹持主体12的安装部40相背两表面。如此,隔振垫100与主体12的安装效果好。
具体地,主体12包括安装部40,安装部40可开设有卡孔,两个夹持面对主体12安装部40的相背两表面进行夹持,夹持面积大,夹持位置能够较为均匀地分布,夹持效果好,进而保证了隔振垫100与主体12的安装效果。第二夹持面38可以是卡部32的底面。
在某些实施方式中,隔振垫100的形状包括圆形、椭圆形、三角形、方形、规则多边形。如此,隔振垫100的设计灵活,可以适应更多需求。
具体地,可以根据实际需要来对隔振垫100的形状进行设计制造,以满足所需的应用场景或设计要求。
在一个实施方式中,隔振垫100的形状为圆形。在一个实施方式中,隔振垫100的形状为椭圆形。在一个实施方式中,隔振垫100的形状为三角形。在一个实施方式中,隔振垫100的形状为方形。在一个实施方式中,隔热垫的形状为规则多边形,规则多边形可以是五边形、六边形等等形状。
可以理解,在其它实施方式中,隔振垫100的形状还可以是圆环状,工字垫状,圆锥状等。在此不作具体限定。
在某些实施方式中,隔振垫100的材质包括橡胶、塑胶。如此,隔振垫100成本低,易于制造。
具体地,隔振垫100可以通过一体成型工艺来制造。在一个实施方式中,隔振垫100的材质是橡胶。在一个实施方式中,隔振垫100的材质是塑胶。
在一个实施方式中,隔振垫100在制造设计时,可以通过以下步骤进行:
步骤1:计算云台300的质量和惯量参数,确定云台300转轴(如横滚轴、偏航轴等)隔振频点的大致区间,确定径向平动方向最低限制隔振频点,并结合云台300左右两端的跨距,大致确定隔振垫100径向和轴向刚度的范围;
步骤2:结合电机直径及云台300与机身的距离,大致给出隔振垫100的直径和深度,在CAE仿真软件中(例如HyperWorks)计算隔振垫100的轴向和径向刚度,如果刚度不满足要求,可以通过调节隔振垫100的厚度,高度和直径等参数来调节,直至得到合适的隔振垫100参数;
步骤3:进一步将隔振垫100模型导入到云台CAE模型计算云台300的隔振频点,解耦率,隔振衰减曲线,以及最严苛工况下的最大应力,综合评估隔振垫100是否满足隔振以及强度要求;
步骤4:增加生产工艺特征形成隔振垫100的最终形态,打样验证隔振垫100的刚度是否和设计值一致,并通过隔振垫100将云台300安装至可移动平台200移动(如无人机试飞)验证隔振垫100隔振效果和强度是否满足要求。
请参图1和图2,本申请实施方式的一种可移动平台200,包括主体12、云台300和隔振垫100,隔振垫100连接在主体12和云台300之间。
上述可移动平台200中,通过沿周向设置的第一连接件18实现与云台300的安装,及通过第二连接件20实现与主体12的安装,主体12上的振动激励可以经由第二连接件20和第一连接件18进行分散隔离,有效地减少了从主体12传递至云台300的振动激励,提升了云台300的增稳效果。
需要指出的是,上述对隔振垫100的实施方式和有益效果的解释说明,也适用于本实施方式的可移动平台200的隔振垫100,为避免冗余,在此不作详细展开。

拍摄组件66可包括电路板76和图像传感器78,连接线72可以连接电路板76,以实现主体12与拍摄装置50的图像数据传输及控制信号传输等。
横滚轴电机60设有贯穿定子70和转子68的第一开孔80,第一开孔80构成过线孔74的一部分。在图示的实施方式中,第一开孔80位于横滚轴电机60的回转中心。可以理解,其它实施方式中,第一开孔80也可以偏离回转中心一定的距离来都达到降低线绕的效果。
在一个实施方式中,可以将电机驱动芯片集成到主体12的核心板上以降低云台300重量且可以达到良好的控制精度,并可以通过连接线72控制电机的运行。
在某些实施方式中,请参图15至图17,后壳64内侧设有导热平面结构82,拍摄组件66包括电路板76和图像传感器78,电路板76包括相背的第一面84和第二面86,图像传感器78安装在第一面84,导热平面结构82与第二面86抵接。如此,可以对拍摄组件66进行散热。
具体地,后壳64开设有第二开孔88,第二开孔88构成过线孔74的一部分。导热平面结构82可以与后壳64上的第二开孔88对应设置,请参图17,导热平面结构82包括连接部90和导热部92,连接部90连接在第二开孔88周围的后壳64部件,导热部92连接在连接部90顶部。导热部92与电路板76的第二面86抵接。导热部92呈平面状,如此可以增加散热面积。后壳64可以采用金属材料或其它适用于散热的材料制成。
在图示的实施方式中,第二开孔88为方形孔,导热部92平面为方形平面。可以理解,在其它实施方式中,第二开孔88和导热部92平面也可以是其他多边形形状或其它形状。
图像传感器78可以输出图像数据,经电路板76处理后,由连接线72输出至主体12或其它外部设备。图像传感器78可以是CCD或CMOS图像传感器78。拍摄装置50还包括前壳94和镜头96,镜头96安装在前壳94并位于图像传感器78前侧。后壳64与前壳94固定连接。
在某些实施方式中,导热平面结构82与第二面86之间设有导热层(图未示)。如此,可以提升散热效率。
具体地,导热层连接导热部92和第二面86,导热层可以减少导热部92和第二面86之间的空气间隙,提升散热接触面积,进而可提升散热效率,保证拍摄装置50工作在合适的工作温度范围。导热层的材质可以是导热硅脂,或其它导热材料。
在本申请的一个实施方式中,可以通过以下步骤实现同轴线中间穿以降低线绕和散热的目的,实现横滚轴的大角度(竖拍)拍摄:
步骤1,将横滚轴电机60定子70与横滚轴轴臂60通过螺丝固定;
步骤2,将步骤1组成的结构与拍摄装置50后壳64通过螺丝固定;
步骤3,将同轴线穿过步骤2组成的结构与拍摄组件66连接;
步骤4,将拍摄装置50后壳64的导热平面涂导热脂形成导热层;
步骤5,将步骤3组成的结构和步骤4形成的结构一起组装进与拍摄装置50前壳94装配完成,实现同轴线的穿轴和拍摄组件66散热,驱动电机实现拍摄装置50的转动控制,检测是否能满足控制拍摄装 置50要求。
在某些实施方式中,可移动平台200包括无人机、无人车、无人船、机器人或拍摄稳定器。如此,可移动平台200的应用范围广,应用场景多。
具体地,在图示的实施方式中,可移动平台200包括无人机,主体12是无人机的机身,云台300通过隔振垫100安装在无人机机身的前端。
在一个实施方式中,可移动平台200包括无人车,主体12是无人车的车身,云台300通过隔振垫100安装在无人车车身的顶部。在其它实施方式中,可移动平台200包括无人船、机器人或拍摄稳定器。云台300的安装位置不限于上述所指的位置,还可以是其它位置,在此不作具体限定。
综上,本申请实施方式的隔振垫100和可移动平台200,至少可以实现以下技术效果:
1、隔振构型空间位置和角度的设计比较简单,受空间位置的约束较少;
2、由于该隔振形式左右和沿径向均对称,容易得到较高的减振解耦率;
3、兼顾低线绕且散热的设计,有效降低线绕同时能兼顾拍摄装置50散热;
4、云台300外包络尺寸和重量都得到更好的优化,对于重量和尺寸要求较小的便携式折叠小型无人机的设计比较有利。
