具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
本申请实施例的车辆包括车身和电动踏杠装置100，电动踏杠装置100安装在车身的底面。换言之，电动踏杠装置100安装在车身的底盘上。
车辆包括车门，电动踏杠装置100邻近车门设置且位于车门下方。在一些实施例中，车辆具有两个车门，车门为侧门。本申请并不限于此，例如，在其他实施例中，车辆可以具有四个车门(侧门)，车身每一侧设有两个侧门，在车身的每一侧均设有一个电动踏杠装置100。车辆还可以具有尾门，车身的尾部设有邻近尾门的电动踏杠装置100。
下面参考图1-图11描述本申请实施例提供的具有防撞功能的电动踏杠装置100的基本结构。本申请实施例的电动踏杠装置100包括踏杠1、伸缩机构2、防撞组件。其中踏杠1 在伸出位置和缩回位置之间可移动。
伸缩机构2包括安装座21、踏杠座22和臂组件23。踏杠1安装在踏杠座22上，安装座21用于安装在车身的底面上。臂组件23连接在安装座21与踏杠座22之间，以驱动踏杠1在伸出位置和缩回位置之间移动。例如，臂组件23可以分别与安装座21和踏杠座22可枢转地相连，臂组件23在驱动装置(例如电机)的驱动下带动踏杠1在伸出位置和缩回位置之间移动。
防撞组件包括第一防撞部件3和第二防撞部件4。其中，第一防撞部件3安装到踏杠1上，第二防撞部件4安装到安装座21上。
第一防撞部件3包括第一防撞座31、第一防撞轴32和第二防撞轴33，第一防撞轴32和第二防撞轴33安装在第一防撞座31上且彼此间隔开。第二防撞部件4包括第二防撞座41、第一防撞凹槽42和第二防撞凹槽43，第一防撞凹槽42和第二防撞凹槽43设在第二防撞座41上。
其中在缩回位置，第一防撞轴32配合在第一防撞凹槽内42且第二防撞轴33配合在第二防撞凹槽43内，在伸出位置，第一防撞轴32从第一防撞凹槽42内脱离且第二防撞轴33从第二防撞凹槽43内脱离。换言之，在缩回位置，通过第一防撞轴32与第一防撞凹槽内42的配合以及第二防撞轴33与第二防撞凹槽43的配合，第一防撞部件3与第二防撞部件4相接合，从而将踏杠1锁定在缩回位置。在踏杠1向伸出位置移动时，第一防撞轴32从第一防撞凹槽42内脱离且第二防撞轴33从第二防撞凹槽43内脱离，即第一防撞部件3脱离第二防撞部件4，以允许踏杠1从缩回位置向伸出位置移动。
通过第一防撞轴32和第一防撞凹槽内42的配合和脱离以及第二防撞轴33和第二防撞凹槽43的配合和脱离，以实现第二防撞部件4对第一防撞部件3的锁定和释放，进而实现踏杠1在缩回位置和伸出位置之间移动。
需要说明的是，第二防撞部件4可以在踏杠1离开缩回位置之前释放第一防撞部件3，也可以在踏杠1离开缩回位置同时释放第一防撞部件3，即第一防撞部件3脱离第二防撞部件4的过程可以与踏杠1离开缩回位置的过程同时进行。第一防撞轴32和第一防撞凹槽内42的配合或脱离以及第二防撞轴33和第二防撞凹槽43的配合或脱离可以同时进行也可前后进行，本申请对此不做限制。
在一些实施例中，在缩回位置，踏杠1贴靠在车身的侧面的下沿处。例如踏杠1沿竖直方向定向且贴靠在车身的侧面的下沿处，由此踏杠1盖住车身的下沿。
在另一些实施例中，在缩回位置，踏杠1倾斜地贴靠在车身的底面与车身的侧面的交界处。换言之，踏杠1相对于车身的侧面倾斜设置，且贴靠在车身的底面和车身的侧面的交界处，由此踏杠1可以盖住车身的底面的外沿和车身的侧面的下沿。由此，通过防撞组 件在缩回位置锁定踏杠1，踏杠1可以用作车辆的保险杠而起到防护功能，以保护车身以防止车辆1被撞击或刮蹭。
本申请实施例的电动踏杠装置通过防撞组件将踏杠锁定在缩回位置，防撞组件中的第一防撞部件与第二防撞部件通过两组轴-槽结构的配合，使踏杠受到异物撞击时受力均衡，进一步提高了踏杠在缩回位置的稳定性，提高了电动踏杠装置的防撞性能。并且，防撞组件还可以锁定和支撑处于缩回位置的踏杠，在踏杠收到外力冲击时可以避免损坏电动踏杠装置的伸缩机构，延长伸缩机构的使用寿命。此外，处于缩回位置的踏杠可以用作车辆的保险杠，起到一定的防护功能，避免车辆被撞击或刮蹭。
在一些实施例中，如图8所示，安装座21包括安装座板211、第一吊板212和第二吊板213，第一吊板212从安装座板211的一侧向下延伸，第二吊板213从安装座板211的另一侧向下延伸，第一吊板212和第二吊板213间隔开且彼此相对。具体地，第一吊板212和第二吊板213在踏杠1的延伸方向上间隔设置并彼此相对。优选地，第一吊板212和第二吊板213所在平面大体平行，且第一吊板212和第二吊板213在踏杠1的延伸方向上彼此对齐。
进一步地，壁组件23的一端在踏杠1的延伸方向上夹设与第一吊板212和第二吊板213之间。具体地，如图8所示，第一吊板212和第二吊板213上均开设有至少一个安装孔214，第一吊板212上的安装孔214与第二吊板213的安装孔214在踏杠1的延伸方向上一一相对，螺栓穿过安装孔214将壁组件23的一端与安装座21可枢转地相连。
在一些实施例中，第二防撞部件4包括防撞座板44和从防撞座板44向下延伸出的防撞耳板45，防撞座板44固定在安装座21的顶面上，第一防撞凹槽41和第二防撞凹槽42形成在防撞耳板45的下端。
具体地，如图8所示，防撞座板44固定在安装座板211的顶面上，防撞座板44与安装座板211大体平行。防撞耳板45从防撞座板44的下表面的一侧向下延伸且与第一吊板212相邻，并且防撞耳板45大体平行于第一吊板212延伸。也就是说，防撞耳板45从防撞座板44的邻近第一吊板212的一侧向下延伸。可选地，防撞耳板45的下端位于第一吊板212的下端的下方。
进一步具体地，如图8所示，防撞耳板45包括耳板体451和与耳板体451成一体的耳座452，耳板体451的上端与防撞座板44相连，耳板体451的下端与耳座452相连，即防撞耳板45的下端为耳座452的下端。第一防撞凹槽42和第二防撞凹槽43形成在耳座452的下端。第一防撞凹槽42和第二防撞凹槽43均沿踏杠1的延伸方向延伸，并在垂直于踏杠1的延伸方向的第一方向间隔设置。需要说明的是，第一方向为垂直与车身的侧面的水平方向。如图8所示，耳座452的厚度大于耳板体451的厚度，因此，第一防撞凹槽42和 第二防撞凹槽43在其延伸方向上具有一定的尺寸，增大了与第一防撞轴32和第二防撞轴33的接触面积，进一步提高了第二防撞部件4对第一防撞部件3的锁定时的可靠性，提高了踏杠1处于缩回位置时的稳定性。
在一些实施例中，如图8所示，第一防撞凹槽42和第二防撞凹槽43在水平方向上对齐，也就是说，第一防撞凹槽42和第二防撞凹槽43的相对高度一致。可替换地，第一防撞凹槽42和第二防撞凹槽43之间在上下方向上可以具有一定的高度差，例如第一防撞凹槽42可以位于第二防撞凹槽43的上方，也可以位于第二防撞凹槽43的下方。可选地，第一防撞凹槽42和第二防撞凹槽43的相对位置关系可以根据踏杠座22的移动方式设置，例如，通过对第一防撞凹槽42和第二防撞凹槽43的相对位置关系的设计，使第一防撞轴32与第一防撞凹槽42之间的脱离(配合)，以及第二防撞轴33与第二防撞凹槽43之间的脱离(配合)同时进行。
在一些实施例中，为了使防撞座板44安装在安装座21上，防撞座板44的外侧面一体地设有折板部441，折板部441设有连接通孔442，安装座21的外侧面设有螺纹孔215，防撞座板44通过穿过连接通孔442配合在螺纹孔215内的螺纹件5紧固到安装座21上。
具体地，如图8所示，防撞座板44的靠近踏杠1的一侧，即其外侧，设有折板部441，折板部441从防撞座板44的所述一侧向下延伸。折板部441上开设有两个沿踏杠1的延伸方向间隔设置的连接通孔442，可以理解的是，连接通孔442位于防撞座板44的下表面的下方。安装座21的安装座板211的靠近折板部441的外侧面设有两个螺纹孔215，两个螺纹孔215与两个连接通孔442在所述第一方向上一一对应。两个螺纹件5从外向内穿过连接通孔442配合在螺纹孔215内，从而将防撞座板44与安装座板211相互固定。
在一些实施例中，第一防撞座3包括连接座34、第二耳板35和第二耳板36。连接座34与踏杠1相连，第一耳板35的一端与连接座34相接，第二耳板36的一端与连接座34相接，第一耳板35和第二耳板36彼此相对且间隔开。具体地，在图8所示的实施例中，第一耳板35和第二耳板36在踏杠1的延伸方向上间隔并对其设置，第一耳板35和第二耳板36所在平面大体平行。

如图3和图4所示，在伸出位置，第一耳板35和第二耳板36从连接座34向上向内延伸，即向靠近第二防撞部件4延伸，如图1和图2所示，在缩回位置，第一耳板35和第二耳板36从连接座34水平向内延伸，与耳座452的下端相配合。
在一些优选实施例中，第一防撞轴32的横截面的外周轮廓与第一防撞凹槽42的内周轮廓相适配，第二防撞轴33的横截面的外周轮廓与第二防撞凹槽43的内周轮廓相适配，以使在缩回位置，第一防撞轴32更好地接合在第一防撞凹槽42内，第二防撞轴33更好地接合在第二防撞凹槽43内。
可选地，第一防撞轴32(第二防撞轴33)的横截面为圆形，第一防撞凹槽42(第二防撞凹槽43)的内周轮廓也为圆形。或者，第一防撞轴32(第二防撞轴33)的横截面为非圆形，第一防撞凹槽42(第二防撞凹槽43)的内周轮廓也为非圆形，例如四边形、六边形等的多边形。
在一些实施例中，第一防撞轴32和第二防撞轴33的横截面形状不同，例如，在图8所示实施例中，第一防撞轴32的横截面为圆形，第二防撞轴33的横截面为正六边形，第一防撞凹槽42的内周轮廓为与第一防撞轴32的横截面相适配的圆形，第二防撞凹槽43的内周轮廓为与第二防撞轴33的横截面相适配的正六边形。可以理解的是，第一防撞轴32和第二防撞轴33的横截面形状的横截面并不限于此。可替换地，第二防撞轴33的横截面为其他正多边形。第一防撞轴32和第二防撞轴33的横截面形状不同，可以进一步提高防撞组件对处于缩回位置的踏杠1的锁紧程度，提高其稳定性。
在一些实施例中，为了使连接座34与踏杠1相连，电动踏杠装置100还包括压板6。如图7所示，压板6包括板体61和从板体61的下表面向下延伸的第一凸台62，压板6具有贯通板体61和第一凸台62的第一螺纹孔63。踏杠1的内侧设有连接板11，连接板11设有第一贯通孔，连接座34设有第一凹槽341，第一凹槽341的底壁上设有第一通孔(图中未示出)，连接板11压在连接座34上，板体61压在连接板11上且第一凸台62穿过第一贯通孔配合在第一凹槽341内，因此，压板6、连接座34与踏杠1通过穿过第一通孔配合在第一螺纹孔63内的螺纹紧固件64紧固在一起。
踏杠座22包括踏杠座体221、第一踏杠座耳222和第二踏杠座耳223，第一踏杠座耳222和第二踏杠座耳223与踏杠座体221一体地相接，且第一踏杠座耳222和第二踏杠座耳223在踏杠1的延伸方向上彼此间隔地相对。具体地，如图8所示，第一踏杠座耳222的一端与踏杠座体221相连并向臂组件23延伸，第二踏杠座耳223的一端与踏杠座体221相连并向臂组件23延伸，臂组件23的下端位于第一踏杠座耳222和第二踏杠座耳223之间，并与第一踏杠座耳222和第二踏杠座耳223可枢转地相连。
