Description

脚踏板设备和具有它的车辆 技术领域
本发明涉及一种脚踏板设备和具有它的车辆。
背景技术
车用脚踏板是安装在车门下面供人们上下车用。从人机工程角度考虑，脚踏板相对地面高度通常在15厘米左右时，人员上下车最方便，但从车辆的通过性角度考虑，脚踏板的安装高度应不低于车辆的最小地隙。因此，相关技术中的脚踏板在车辆通过性和人上下汽车的方便性之间往往存在难以协调的矛盾，存在改进的需求。
发明内容
本申请是基于发明人对以下事实和问题的发现和认识做出的：
相关技术中，为了便于人员上下车辆，在车门下面安装有固定脚踏板，但是为了兼顾性，固定脚踏板距离地面较高，使用方便性差。为此，相关技术中提出了具有伸缩功能的脚踏板，使用时，脚踏板伸出供人员上下车用，不使用时，脚踏板缩回到车体下面。但是，具有伸缩功能的脚踏板在缩回时无法起到防护功能，尤其是无法起到防护车辆侧面(例如车门)的功能。

具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。
在本发明的描述中，需要理解的是，术语“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
下面首先结合图1-图8描述根据本发明实施例的车辆A。
如图1-图4所示，根据本发明实施例的车辆A包括车体10、车门20和脚踏板设备30。
安装部车门20在打开位置和关闭位置之间可移动地安装在车体10上。脚踏板设备30安装在车体10上且邻近车门20。脚踏板设备30包括固定踏板31和伸缩踏板装置32。固定踏板安装在车体10的侧面、位于车门20下方且从车体10向外(例如，在图1中向左)延伸出。车体10具有位于下面的安装部11，伸缩踏板装置32安装在安装部11上。伸缩踏板装置32包括在伸出位置与缩回位置之间可伸缩的伸缩机构322和安装在伸缩机构322上的伸缩踏板321。
如图1和3所示，在伸出位置，伸缩踏板321的至少一部分从固定踏板31下方向外延伸超出固定踏板31，固定踏板31与伸缩踏板321形成高度不同的两个台阶，由此便于用户上下车。
如图2和4所示，在缩回位置，伸缩踏板321向内缩回到固定踏板31下方，不会降低车辆的通过性能。即使伸缩踏板321移动到缩回位置，由于固定踏板31固定在车体10的侧部，可以起到防护车体10的侧面的功能。
根据本发明实施例的脚踏板设备30，通过在固定踏板31的下方设置由伸缩机构322驱动在伸出位置与缩回位置之间移动的伸缩踏板321，方便了用户上下车，提升用户体验，并且不会降低车辆的通过性能。并且固定踏板31可以对车辆A的侧面(例如车门20)起到防护作用，防止损坏车门20等部件。
根据本发明实施例的车辆A通过设置具有固定踏板31和伸缩踏板321的脚踏板设备30，从而具有使用方便性好、通过性能好且具有防护车辆A侧面的尤其是车门20的功能。
下面结合图1-图8描述根据本发明实施例的脚踏板设备30。
如图1-图4所示，根据本发明一些实施例的脚踏板设备30包括：固定踏板31和伸缩踏 板装置32。固定踏板31和伸缩踏板装置32分别安装在车体10上，例如，固定踏板31安装在车门20下面的车体10的侧部，伸缩踏板装置32安装在车体10的下面(例如车辆的底盘上)。
在一些示例中，固定踏板31的下表面设有凹槽311。凹槽311的顶面沿从内向外的方向向上倾斜，凹槽311的前表面沿从上向下的方向向外倾斜。这里，需要理解的是，内外方向为图1中示出的左右方向。例如，凹槽311的“前表面”是指如图3所示的凹槽311的左侧面。
如图4所示，在缩回位置，伸缩踏板321的一部分容纳在凹槽311内，可以理解的是，在缩回位置，整个伸缩踏板321都可以容纳在凹槽311内。伸缩踏板321的前表面(图4所示的左侧面)与凹槽311的前表面贴合，伸缩踏板321的顶面与凹槽311的顶面贴合，从而在缩回位置，可以更好地将伸缩踏板321隐藏在车体10下面，进一步提高了车辆通过性能。
换言之，伸缩踏板321在伸出位置与固定踏板31协作，构成供用户上车的踏板，提高了便利性；在缩回位置，伸缩踏板321位于固定踏板31的内侧和下方，伸缩踏板321从车辆A的侧面不会露出，因此伸缩踏板321不会影响整车外观和通过性。并且，在缩回位置固定踏板31起到防护车辆A侧面的作用。
可选地，伸缩机构322为四连杆机构322a、五连杆机构322b、六连杆机构322c(322d)中的一种。
例如，在图5所示的实施例中，伸缩机构322为四连杆机构322a，伸缩机构322包括安装支座3221、踏板支座3222以及连接在安装支座3221和踏板支座3222之间的臂组件3223。安装支座3221安装在安装部11上。伸缩踏板321安装在踏板支座3222上。
臂组件3223包括第一臂32231和第二臂32232。第一臂32231的第一端32231a通过第一连接销轴3223a可枢转地连接在安装支座3221上，第一臂32231的第二端32231b通过第二连接销轴3223b可枢转地连接在踏板支座3222上。这里的“第一端32231a”是指如图5所示的第一臂32231的上端，“第二端32231b”是指如图5所示的第一臂32231的下端。
类似地，第二臂32232的第一端32232a通过第三连接销轴3223c可枢转地连接在安装支座3221上，第二臂32232的第二端32232b通过第四连接销轴3223d可枢转地连接在踏板支座3222上。第一臂32231和第二臂32232中的至少一个可以与电机(图5中未示出)相连。因此，所述电机驱动第一臂32231和第二臂32232中的至少一个枢转，进而第一臂32231和第二臂32232中的至少一个通过踏板支座3222驱动伸缩踏板321伸出和缩回。
在图6所示的实施例中，伸缩机构322为五连杆机构322b，伸缩机构322包括安装支座3221、踏板支座3222以及连接在安装支座3221和踏板支座3222之间的臂组件3223。伸缩踏板321安装在踏板支座3222上。
更具体地，臂组件3223包括第一臂32231、第二臂32232和第三臂32233。第一臂32231具有第一端32231a和第二端32231b。这里的“第一端32231a”是指如图6所示的第一臂32231的上端，“第二端32231b”是指如图6所示的第一臂32231的下端。第一臂32231的第一端32231a通过第一连接销轴3223a可枢转地连接在安装支座3221上，第一臂32231的第二端32231b通过第二连接销轴3223b可枢转地连接在踏板支座3222上。
第二臂32232具有第一端32232a和第二端32232b，第二臂32232的第一端32232a通过第三连接销轴3223c可枢转地连接在安装支座3221上。第三臂32233具有第一端32233a和第二端32233b。第二臂32232的第二端32232b与第三臂32233的第一端32233a通过第五连接销轴3223e可枢转地连接在一起，第三臂32233的第二端32233b通过第四连接销轴3223d与踏板支座3222可枢转地连接。
第一臂32231和第二臂32232中的至少一个可以与电机(图6中未示出)相连。因此，所述电机驱动第一臂32231和第二臂32232中的至少一个枢转，进而第一臂32231和第二臂32232中的至少一个通过踏板支座3222驱动伸缩踏板321伸出和缩回。通过采用五连杆机构形式的伸缩机构322，可以进一步提高伸缩机构322在伸缩过程中的稳定性和准确性。
在本发明的一些具体实施例中，伸缩机构322为六连杆机构322c(322d)且包括：安装支座3221、踏板支座3222、臂组件3223、轨迹控制板3224、轨迹控制轴3225。
臂组件3223包括第一臂32231、第二臂32232和第三臂32233。第一臂32231的第一端32231a与安装支座3221可枢转地连接，第一臂32231的第二端32231b与踏板支座3222可枢转地连接。第二臂32232的第一端32232a与安装支座3221可枢转地连接。第三臂32233的第一端32233a与第二臂32232的第二端32232b可枢转地连接，第三臂32233的第二端32233b与踏板支座3222可枢转地连接。轨迹控制板3224安装在第一臂32231上且具有轨迹控制槽3224a。轨迹控制轴3225的第一端***到轨迹控制槽3224a内且在轨迹控制槽3224a内可移动地，轨迹控制轴3225的第二端安装在与第二臂32232和第三臂32233中的至少一个上。
轨迹控制板3224安装在第一臂32231、第二臂32232和第三臂32233中的一个臂上且形成有轨迹控制槽3224a。轨迹控制轴3225的第一端***到轨迹控制槽3224a内且在轨迹控制槽3224a内可移动。轨迹控制轴3225的第二端安装在与所述一个臂在横向(图7中的大体左右方向)上相对的臂上。
在本发明的一些具体示例中，如图7所示，轨迹控制板3224安装在第一臂32231上。轨迹控制轴3225的第一端***到轨迹控制槽3224a内且在轨迹控制槽3224a内可移动，轨迹控制轴3225的第二端连接到与第一臂32231在横向上相对的臂上。
第一臂32231的第一端32231a(图7中的上端)通过第一连接销轴3223a与安装支座 3221可枢转地相连，而其第二端32231b(图7中的下端)通过第二连接销轴3223b与踏板支座3222可枢转地相连。更具体地，第一连接销轴3223a穿过第一臂32231的上端的孔和安装支座3221上的孔，从而将第一臂32231的上端与安装支座3221可枢转地相连。第二连接销轴3223b穿过第一臂32231下端的孔和踏板支座3222上的孔，从而将第一臂32231下端与踏板支座3222可枢转地相连。
第二臂32232的第一端32232a(图7中的上端)通过第三连接销轴3223c与安装支座3221可枢转地相连，而其第二端32232b(图7中的下端)通过第五连接销轴3223e与第三臂32233的第一端32233a(图7中的上端)可枢转地相连。更具体地，第三连接销轴3223c穿过第二臂32232上端的孔和安装支座3221上的孔，从而将第二臂32232的上端与安装支座3221可枢转地相连。第五连接销轴3223e穿过第二臂32232下端的孔和第三臂32233上端的孔将第二臂32232和第三臂32233可枢转地连接。
第三臂32233的下端通过第四连接销轴3223d与踏板支座3222可枢转地相连，更具体地，第四连接销轴3223d穿过第三臂32233下端的孔和踏板支座3222上的孔，从而将第三臂32233的下端与踏板支座3222可枢转地相连。
在图7所示的实施例中，用于连接第二臂32232的下端与第三臂32233的上端的第五连接销轴3223e用作轨迹控制轴3225。换言之，轨迹控制轴3225与第五连接销轴3223e为同一个轴,第五连接销轴3223e的第一端***到轨迹控制槽3224a内且在轨迹控制槽3224a内可以移动，第五连接销轴3223e的第二端穿过第二臂32232下端的孔和第三臂32233上端的孔从而将第二臂32232的下端与第三臂32233的上端可枢转地连接。
然而，需要理解的是，本发明并不限于此，轨迹控制轴3225可以为单独的轴，例如可以安装到第二臂32232上，或者安装到第三臂32233上。
如图7所示，轨迹控制槽3224a为形成在轨迹控制板3224内的封闭曲线凹槽311。轨迹控制板3224可以与第一臂32231一体地连接，例如焊接到第一臂32231上，或者轨迹控制板3224可以为第一臂32231的一部分。可选地，轨迹控制板3224也可以通过螺栓安装到第一臂32231上。
根据本发明实施例的伸缩机构322，通过轨迹控制槽3224a和***到其内的轨迹控制轴3225，可以控制踏板支座3222(从而控制安装到其上的伸缩踏板321)的运动轨迹，并且踏板支座3222的行程增大，通过改变轨迹控制槽3224a的位置或形状，或轨迹控制轴3225的位置或它们的组合，可以方便、精确地改变踏板支座3222的运动轨迹，从而伸缩机构322的安装灵活，例如可以安装到车辆A底盘的中部，适用性好。
在一些可选的示例中，轨迹控制轴3225的第二端安装到第二臂32232上，例如焊接或通过螺栓安装到第二臂32232上。在另一些可选的示例中，轨迹控制轴3225的第二端安装 到第三臂32233上，例如焊接或通过螺栓安装到第三臂32233上。
在本发明的一些实施例中，轨迹控制板3224可以安装到第二臂32232上，轨迹控制轴3225的第二端安装到第一臂32231上。在本发明的另一些实施例中，轨迹控制板3224可以安装到第三臂32233上，轨迹控制轴3225的第二段安装到第一臂32231上。简言之，当轨迹控制板3224安装到第二臂32232或第三臂32233上时，轨迹控制轴3225的第二端安装到第一臂32231上。
在本发明的另一些具体实施例中，伸缩机构322包括：安装支座3221、踏板支座3222、臂组件3223、轨迹控制杆3226、轨迹控制轴3225。
臂组件3223包括第一臂32231、第二臂32232和第三臂32233。第一臂32231的第一端与安装支座3221可枢转地连接，第一臂32231的第二端与踏板支座3222可枢转地连接。第二臂32232的第一端与安装支座3221可枢转地连接。第三臂32233的第一端与第二臂32232的第二端可枢转地连接，第三臂32233的第二端与踏板支座3222可枢转地连接。轨迹控制杆3226的一端可枢转地安装在第一臂32231上。轨迹控制轴3225的第一端与轨迹控制杆3226的第二端可枢转地连接，轨迹控制轴3225的第二端安装在第二臂32232和第三臂32233中的至少一个上。
在图8所示的实施例中，轨迹控制杆3226为长条状，侧面为大体长圆形，轨迹控制杆3226的两端分别形成有通孔3226a(3226b)。轨迹控制杆3226的第一端通过第六连接销轴3223f可转动地安装到第一臂32231上，轨迹控制轴3225的第一端可旋转地***到第二端的通孔3226a内，而轨迹控制轴3225的第二端安装到第三臂32233上。更具体而言，第二臂32232和第三臂32233通过第五连接销轴3223e相连，轨迹控制轴3225焊接或通过螺栓安装到第三臂32233上。第五连接销轴3223e的第一端可旋转地***到通孔3226a内，第五连接销轴3223e的第二端将第二臂32232和第三臂32233相连。
如图8所示，在第一臂32231的横向外侧面上设有大体V形槽32231c，在V形槽32231c处在第一臂32231上形成有孔32231d，轨迹控制杆3226的第一端通过穿过通孔3226b***到孔32231d内的第六连接销轴3223f在V形槽32231c内与第一臂32231相连。通过设置V形槽32231c可以方便轨迹控制杆3226的转动。当然，本发明并不限于此，例如轨迹控制杆3226的第一端可以通过第六连接销轴3223f直接连接在第一臂32231的侧面。
当车门20打开时，伸缩机构322运动到伸出位置，乘客可以通过伸缩踏板321和固定踏板31上车。当车门20关闭时，伸缩机构322向缩回位置移动。通过轨迹控制杆3226和轨迹控制轴3225可以方便和精确地控制踏板支座3222(伸缩踏板321)的运动轨迹。
根据本发明实施例的脚踏板设备，具有固定踏板和能够在伸出位置和缩回位置之间移动的伸缩踏板321，不但提高了用户使用脚踏板设备上车的方便性，车辆的通过性能好，且固 定踏板可以防护车辆侧面。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
