具体实施方式
为了便于理解本申请,下面结合附图和具体实施例,对本申请进行更详细的说明。需要说明的是,当元件被表述“固定于”/“固接于”/“安装于”另一个元件,他可以直接在另一个元件上、或者其间可以存在一个或多个居中的元件。当一个元件被表述“连接”另一个元件,他可以是直接连接到另一个元件、或者其间可以存在一个或多个居中的元件。本说明书所使用的术语“垂直的”、“水平的”、“左”、“右”、“内”、“外”以及类似的表述只是为了说明的目的。
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申请的技术领域的技术人员通常理解的含义相同。在本申请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,不是用于限制本申请。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,下面所描述的本申请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。
在本说明书中,所述“安装”包括焊接、螺接、卡接、粘合等方式将某一 元件或装置固定或限制于特定位置或地方,所述元件或装置可在特定位置或地方保持不动也可在限定范围内活动,所述元件或装置固定或限制于特定位置或地方后可进行拆卸也可不能进行拆卸,在本申请实施例中不作限制。
本申请的发明人在实现本申请的过程中发现:在将距离测量装置安装于例如扫地机器人时,即使采用固定座和保护罩盖罩在该距离测量装置上,但由于该固定座和保护罩并非距离测量装置的一部分,其并没有与距离测量装置进行贴合,也不能盖罩在距离测量装置的安装室上,因此这种固定座和保护罩不会阻挡杂质缠绕皮带。因此,在包括距离测量装置和盖罩在该距离测量装置上的固定座和保护罩的扫地机器人中,其恰恰存在本专利所需要解决的技术问题,即杂质会通过保护罩,以及保护罩与固定座之间的间隙进入安装室,会导致皮带卡死。
请一并参阅图1与图2,其分别示出了本申请第一实施例提供的距离测量装置的立体示意图及爆炸示意图,该距离测量装置包括基座100、挡板200、第一传动轮300、第二传动轮400、连接件500以及驱动部件600。其中,基座100包括基板110以及侧壁120,该侧壁120可以自基板110延伸得到,也可以独立于基板110,与基板一端固定连接。挡板200与基板110相对设置,并盖罩部分基板110。第一传动轮300、第二传动轮400和连接件500构成一种传动机构。第一传动轮300及第二传动轮400均可转动地安装于基板110,且均位于基板110靠近挡板200的一端。连接件500同时绕设于第一传动轮300及第二传动轮400,其用于在第一传动轮300转动时,带动第二传动轮400转动。驱动部件600与第一传动轮300连接,并用于驱动第一传动轮300转动。上述侧壁120至少部分围设在第一传动轮300的外周,挡板200贴合于侧壁120围设在第一传动轮300外周的部分,且基板110、挡板200、侧壁120以及第二传动轮400共同围成一安装室,第一传动轮300收容于该安装室。
对于上述基座100,请参照图3,其示出了基座100的立体示意图,请同时结合图1与图2,基座100包括基板110与侧壁120。本实施例中,侧壁120的一端与基板110的边缘垂直连接,另一端向挡板200延伸。侧壁120是一种完整的侧壁,其具有大致均匀的高度;从而,侧壁120与基板110共同围成一收容槽,该收容槽用于收容上述的第一传动轮300及第二传动轮400,即是:侧壁120围设在第一传动轮300及第二传动轮400的外周。
对于上述挡板200,请参照图4与图5,其分别示出了挡板200的两个方向的立体示意图,请同时结合图1至图3,挡板200整体呈板状结构,其与上述基板110相对设置并盖罩基板110的部分。挡板200整体收容于上述的收容槽,且其与侧壁120围设在第一传动轮300外周的部分相互贴合。沿平行于第一传动轮300指向第二传动轮400的方向,挡板200的一端覆盖上述第一传动轮300,另一端向第二传动轮400延伸至第二传动轮400边缘,且于上述平行于第一传动轮300指向第二传动轮400的方向,挡板200靠近第二传动轮400的一端的形状与第二传动轮400的外形相适配;本领域的技术人员可以理解的,为避免挡板200对第二传动轮400造成干涉,挡板200靠近第二传动轮400的一端与第二传动轮400之间应具有极小的间隙,挡板200靠近第二传动轮400的一端呈与第二传动轮400侧部轮廓相适配的弧形形状或近似弧形形状。则,基板110、挡板200、侧壁120以及第二传动轮400共同围成上述安装室,基座100、挡板200与第二传送轮400两两之间围合处可完全密封,以阻止该距离测量装置外部的杂物进入该安装室,第一传动轮300收容于该安装室。当然,由于安装室完全密封将大幅提升该距离测量装置的制造成本与装配难度,故在一些实施例中,上述基座100、挡板200与第二传送轮400两两之间在围合处也可以具备一间隙。一般地,该间隙较小,一般控制在5毫米(mm)内;例如,3mm,2mm,或者小于1mm,亦或是小于5mm的其他值。值得一提的是,本申请文件中所述的“挡板与侧壁围设在第一传动轮外周的20部分相互贴合”意为,挡板200与侧壁120围设在第一传动轮300外周的部分外形轮廓适配,并相互接触;如本实施例中,挡板200与侧壁120的相应位置的轮廓均是C形,挡板200的侧面与侧壁120的侧面贴合;当然其他实施例中,也可以是挡板200朝向基板110的一面与侧壁120的顶面贴合,所述顶面就是所述侧壁120的远离所述基板110的端面。
为避免挡板200过多地伸入上述收容槽,而导致挡板200与第一传动轮300发生干涉,上述基座100还包括设于基板110及挡板200之间的至少一个限位筋130。具体请参照图3,限位筋130的一端与基板110连接,另一端向挡板200延伸,于基板110指向挡板200的方向,限位筋130远离基板110的一端与基板110之间的距离,大于第一传动轮300远离基板110的一端与基板之间的距离。挡板200承载于上述至少一个限位筋130,并与基板110固定连接,限位筋130远离基板110的一端与挡板200抵接,以使限位筋130稳固牢靠地支撑挡板 200。可以理解的是,在本申请的其他实施例中,限位筋还可以是一端与挡板连接,另一端向基板延伸并与基板抵接,从而为挡板提供支撑,即是:限位筋的一端与基板及挡板中的一个固定,限位筋的另一端与基板及挡板中的另一个抵接。
本实施例中,挡板200与基座100的基板110卡接固定。具体的,挡板200靠近基板110的一端设有卡钩210,该卡钩210包括连接部211及卡扣部212。其中,连接部211的一端与上述挡板200连接,另一端向基板110延伸;卡扣部212设于连接部211远离挡板200的一端,基板110于对应卡钩210处设有通槽,上述卡扣部212穿过所述通槽,并与基板110远离挡板200的一面抵接,从而实现挡板200与基板110之间的固定连接。可以理解的是,在本申请的其他实施例中,卡钩还可以是设置在基板110上,相应地,挡板200于与卡钩对应的位置设有通槽,该卡钩的卡扣部穿过挡板上的通槽,并与挡板200远离基板110的一面抵接固定。应当理解:在本申请的其他实施例中,挡板200及基座100还能够通过卡接以外的其他方式实现固定连接,如螺纹连接、胶水粘接、超声波连接等,在此不一一限定。
进一步地,为便于挡板200在安装过程中定位安装,挡板200于与上述侧壁120贴合处设有至少一个凹槽220,相应地,侧壁120设有与凹槽220相适配的凸起140,该凸起140插入上述凹槽220。上述凸起140及凹槽220的配合一方面便于挡板200的定位安装,另一方面还能够避免挡板200于平行于基板110的平面内发生滑动。可以理解的是,在本申请的其他实施例中,凹槽还可以设置于侧壁120,相应地,凸起设置于挡板,挡板200及基座100通过该凹槽及凸起实现定位安装,以及于平行于基板110的平面的限位。
为进一步避免挡板200承载于各限位筋130时于平行于基板110的平面内发生滑动,该距离测量装置还包括定位筋150。定位筋150的一端固定于基板110靠近挡板200的一端,另一端向挡板200延伸。挡板200于对应定位筋150处设有与定位筋150相适配的定位槽230,定位筋150插入定位槽230,定位筋150与侧壁120共同配合以阻止挡板200于平行于基板110的平面内运动。本实施例中,定位筋150于基板110平面上呈条状延伸,其设于第一传动轮300与第二传动轮400之间,并将第一传动轮300与第二传动轮400分隔开,定位筋150的两端均与侧壁具有一定间隙,连接件500可穿过上述间隙从而整体绕设在 第一传动轮300及第二传动轮400。定位槽230与定位筋150对应,且沿平行于第一传动轮300指向第二传动轮400的方向延伸至贯通挡板200,该定位槽230使挡板200靠近第二传动轮400的一端形成两个翼部240。定位筋150插入上述定位槽230,并与定位槽230远离第二传动轮400的壁部抵接,进而与上述围设在第一传动轮300外周的部分共同配合,以将挡板约束在两者围成的轮廓之间,从而阻止挡板200于平行于基板110的平面内运动。
对于上述第一传动轮300、第二传动轮400及连接件500,请参照图2,第一传动轮300及第二传动轮400均可转动地安装于基座100;连接件500整体呈封闭的条状结构,其同时绕设于第一传动轮300及第二传动轮400,其能够在第一传动轮300转动的同时带动第二传动轮400转动。第一传动轮300、第二传动轮400及连接件500均收容于上述收容槽,即是:第一传动轮300、第二传动轮400及连接件500均位于基板110靠近挡板200的一端,基板110与侧壁120共同包围第一传动轮300及第二传动轮400。本实施例中,第一传动轮300为第一带轮,其通过固定于基座100的驱动部件600的输出端间接地可转动地安装于基座100;第二传动轮400为第二带轮,其通过轴承410可转动地安装于基座100,第二传动轮400远离基板110的一端安装有测距部件,所述测距部件包括镜头、激光发生器、电路板等,以及罩设上述镜头、激光发生器、电路板等的外罩420;连接件500为皮带或橡胶带。值得注意的是,第二传动轮400远离基板110的端面与基板110之间的距离,大于第一传动轮300远离基板110的一端与基板110之间的距离,以使第二传动轮400能够与上述的基板110、侧壁120及挡板200围成上述的安装室。可以理解的是,即使本实施例中的第一传动轮300与第二传动轮400为带轮,连接件500为皮带或橡胶带,但本申请并不局限于此,例如:在本申请其他的一些实施例中,第一传动轮300还可以为第一链轮,相应地,第二传动轮400为第二链轮,连接件500为链条,该链条绕设于第一链轮及第二链轮。在其他实施例中,还可采用通过连杆传动的传动机构。
进一步地,为避免外部的杂物从第二传动轮400与挡板200之间的间隙,以及第二传动轮400与侧壁120之间的间隙进入上述收容槽,进而缠绕在第一传动轮300、第二传动轮400及连接件500中的至少一个,从而第一传动轮300和/或第二传动轮400卡死,该距离测量装置还包括安装板430,具体请参照图 6及图7。第二传动轮400远离基板110的一端伸出上述收容槽;安装板430整体呈扁平的圆柱形板状结构,其固定于第二传动轮400远离基板110的一端,且其整体覆盖第二传动轮400与挡板200之间的间隙以及第二传动轮400与侧壁120之间的间隙,该安装板430与上述挡板200、上述侧壁120及基板110共同围成一整体包围第一传动轮300、第二传动轮400及连接件500传动空间,则,外部的杂物极难进入该传动空间。上述包括外罩420等结构的测距部件安装于安装板430远离基板110的一端。
对于上述驱动部件600,请继续参照图2,该驱动部件600的输出端与第一传动轮300连接,该驱动部件600用于驱动第一传动轮300转动。本实施例中,驱动部件600为电机,该电机的主体固定于基板110远离挡板200的一面,电机的输出端穿过基板110并伸入上述安装室与第一传动轮300连接,即是:第一传动轮300通过驱动部件600间接地可转动地安装于基座100;可以理解的是,在本申请的其他实施例中,第一传动轮300亦可以直接可转动地安装于基座100。应当理解,驱动部件600还可以是其他任何能够实现转动输出的机构,以驱动第一传动轮300转动,如旋转气缸,在此不一一详举。
本申请实施例提供的距离测量装置包括基座100、挡板200、第一传动轮300、第二传动轮400、连接件500以及驱动部件600。其中,基座100包括基板110,该基板110和挡板200相对设置,且挡板200盖罩部分基板110。第一传动轮300及第二传动轮400均可转动地安装于基板110靠近挡板200的一侧,连接件500绕设于第一传动轮300及第二传动轮400。驱动部件600与第一传动轮300连接,用于驱动第一传动轮300转动,即第一传动轮300为主动轮。基座100还包括侧壁120,该侧壁120至少部分围设于第一传动轮300的外周,挡板200贴合于侧壁120围设在第一传动轮300外周的部分,基板110、挡板200以及侧壁120共同包围第一传动轮300,且基板110、挡板200、侧壁120以及第二传动轮400共同围成一整体包围第一传动轮300的安装室。则,外部的杂物极难进入上述安装室并缠绕在第一传动轮,从而避免了主动轮被杂物直接缠绕卡死的技术问题。
此外,第二传动轮400远离基板110的一端还设有安装板430,该安装板430与上述挡板200、上述侧壁120及上述基板110共同围成一整体包围第一传动轮300、第二传动轮400及连接件500传动空间,则外部的杂物极难进入该传 动空间,从而消除外部杂物缠绕在第二传动轮400及连接件500引起的传动轮卡死的隐患。
在一些实施方式中,如图1和图2所示,所述挡板200可至少部分地遮盖所述第一传动轮300;例如,可在所述挡板200上开设通孔,所述通孔供第一传动轮300的转轴的一端插设安装,从而所述挡板200会露出所述第一传动轮300的一小部分;或者,所述挡板200并不完全地覆盖第一传动轮300所在的基板110,而是露出一部分第一传动轮300或是露出第一传动轮300周围的一部分基板110。在其他一些实施方式中,所述挡板200可与基板110、侧壁120以及第二传动轮400共同围成较为密闭的空间,从而使所述挡板200完全遮盖所述第一传动轮300。
在一些实施方式中,如图1和图2所示,所述挡板200可至少部分地遮盖所述连接件500。例如,所述挡板200并不完全地覆盖第一传动轮300所在的基板110,仅是部分地遮盖所述连接件500,从而露出一部分第一传动轮300或是露出第一传动轮300周围的一部分基板110。容易理解的是,只要采用了挡板200,其无论是局部或全部地遮盖所述第一传动轮300及与第一传动轮300相连的连接件500,都能够防止挡板200上方范围内的杂物侵入所述传动机构内。
在一些实施方式中,如图1和图2所示,所述测距部件完全地遮盖所述第二传动轮400。由于所述测距部件需要结合在第二传动轮400上,因此所述测距部件的例如直径的尺寸可设计成大于或等于所述第二传动轮400的例如直径的尺寸,从而使得测距部件完全地遮盖所述第二传动轮400。如此,所述测距部件也可起到防止其上方范围内的杂物侵入所述传动机构内的作用,尤其是防止杂物侵入所述传动机构的第二传动轮400内。
应当理解:即使在本实施例中,侧壁120是与基板110一体设置的,但本申请并不局限于此,在本申请的其他实施例中,侧壁120还可以是与挡板200一体设置,侧壁120自挡板200起始延伸至基板110,此时,基座100仍然包括基板110以及自基板110延伸至挡板200的侧壁。
请参照图8,其示出了本申请第二实施例提供的距离测量装置700,请同时结合图1至图7,该距离测量装置700与第一实施例中的距离测量装置的主要不同如下所述。
第一实施例中的距离测量装置的挡板200设有凹槽220,侧壁120上相应地 设有与凹槽220相适配的凸起140,挡板200及基座100通过该凹槽220及凸起140实现定位;挡板200与基座100之间通过卡扣连接固定。
而第二实施例中的距离测量装置700包括基座710与挡板720,挡板720不设有上述凹槽,基座710上相应地亦不设有上述凸起,挡板720是通过定位筋713以及围设在第一传动轮300外周的侧壁712共同配合以实现于平行基板711的平面内的定位;此外,挡板720与基座710之间通过螺纹紧固件721固定连接,具体的,一限位筋上设有螺纹孔,挡板720于对应该螺纹孔处设有通孔,螺纹紧固件721穿过该通孔并伸入上述螺纹孔从而与基板711连接,以将挡板200固定于基座710。
由于第二传动轮通过轴承可转动地安装于基座710,在装配工序上往往先于挡板720安装,则挡板720在安装时,首先要将挡板720的两翼部倾斜插入安装板之下,然后再转动至水平承载于各限位筋上;而在这过程中,第一实施例中凹槽及凸起的设置容易使挡板及基座之间发生干涉,其给挡板的拆装增加一定的难度。故,第二实施例中的挡板720安装时,仅需将其倾斜使两翼部伸入安装板之下,然后转动挡板720至其定位槽与定位筋配合,同时,挡板720的侧部与侧壁712围设于第一传动轮外周的部分贴合,并使挡板720承载于各限位筋即可。故,第二实施例提供的距离测量装置更便于挡板720的拆装,有助于提升工作人员装配挡板720时的效率及体验。同时,螺纹紧固件721的紧固牢度优于卡扣连接。
基于同一发明构思,本申请还提供多个其他实施例的距离测量装置,这些距离测量装置与第一实施例或第二实施例中的距离测量装置具有一定相似度,以下对这些实施例的距离测量装置做出说明,特别是对其相对于第一实施例或第二实施例中的距离测量装置的主要区别做出说明。

在其他实施方式中,所述侧壁11b可为有缺口的侧壁;例如,所述侧壁11b可朝挡板12所在的一侧延伸,这些延伸的侧壁段可具有大致均匀的高度,而每两个相邻的侧壁段之间为缺口(可参见图14所示的侧壁41b);或者,所述缺口可为形成在完整的侧壁中的一个或多个通孔。另外,这些缺口可均匀或不均匀地分布在所述侧壁11b上。如此,所述挡板12与所述基座11和所述侧壁11b可形成半密闭的安装室。
在进一步的一些实施方式中,所述挡板12中可开设多个通孔(可参见图11和图12所示的通孔22a),所述通孔用于阻挡大于所述通孔的杂物侵入到所述传动机构13内。
