具体实施方式
为了使申请的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对申请作进一步详细的说明。虽然附图中公开了示例性实施例，然而应当理解，可以以各种形式实现本申请而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更便于透彻的理解本申请，并且能够将本申请的构思完整的传达给本领域人员。
本申请实施例提供一种用于移动设备的加速踏板组件，其中，移动设备可以是利用自动驾驶技术实现的具有载人功能(如家用轿车、公共汽车等类型)、载货功能(如普通货车、厢式货车、甩挂车、封闭货车、罐式货车、平板货车、集装厢车、自卸货车、特殊结构货车等类型)、工具功能(如物流配送车、巡逻车、环卫车、吸尘车、洗地车、扫地机器人、割草机、高尔夫球车)、娱乐功能(如娱乐车、游乐场自动驾驶装置)或者特殊救援功能(如消防车、救护车等类型)的可移动型设备。移动设备也可以是传统的需要人工驾驶或者操作的移动设备，例如手推式、驾驶式、自走式的洗地车、扫地车、环卫车、清洗机、吸尘车、尘推车等设备。
下文以带有加速踏板组件100的洗地车200为例，对本申请所称的用于移动设备的加速踏板组件和移动设备进行介绍。
如图1～2所示，本实施例提供的用于移动设备的加速踏板组件100包括踏板支架10、踏板20和加速开关30。其中，踏板支架10具有限位端10a。踏板20枢转地连接于踏板支架10，踏板20具有枢转高位和枢转低位，限位 端10a能够限制踏板20由枢转高位向枢转低位旋转时的最大旋转角度。具有行程的加速开关30连接于踏板20。当对踏板20施加外力时(例如踩踏)，踏板20由枢转高位向枢转低位旋转，并向最大行程方向推动加速开关30(加速开关30向洗地车200发送逐渐增大的加速信号，从而控制洗地车200不断加速)，在加速开关30抵达最大行程前，所述限位端10a限制踏板20继续旋转。
此外，当踏板20失去外力作用时，踏板20能够凭借加速开关30的弹性回复力自动地旋转至枢转高位。
进一步地，踏板20由枢转高位向枢转低位的最大旋转角度为18°～24°。
本实施例提供的用于移动设备的加速踏板组件100以限位端10a限制踏板20的枢转，进而限制加速开关30被踏板20推动的行程，避免加速开关30因行程过大而损坏，同时也避免了洗地车200不断加速而速度过快。踏板支架10采用喷塑、电泳、镀锌的碳钢或采用不锈钢，以使踏板支架10能够保证强度和耐腐蚀性。踏板20表面采用不锈钢拉丝工艺处理，既增加耐腐蚀性又比较美观。拉丝工艺是一种金属加工工艺，在金属压力加工中，在外力作用下使金属强行通过模具，金属横截面积被压缩，并获得所要求的横截面积形状和尺寸的加工方法。
本实施例中采用的加速开关30为市售产品(上海一恒科学仪器有限公司，型号YL)，加速开关30的样式如图3所示。
进一步地，踏板支架10包括围合成“U”形的两侧间隔部10b和中央连接部10c，踏板20枢转地设置于两侧间隔部10b，中央连接部10c则成为用于抵接踏板20的限位端10a，使中央连接部10c限制踏板20的最大旋转角度。本领域技术人员应当能够理解，在本实施例中，踏板20的最大旋转角度取决于中央连接部10c的高度。中央连接部10c被设置的越高，踏板20的最大旋转角度越小。
具体地，两侧间隔部10b上设置有轴孔10d，踏板20的底部具有转轴20a，转轴20a枢转地设置于轴孔10d内。更具体地，轴孔10d内设置有铜制的轴套10e，转轴20a为法兰螺栓，法兰螺栓穿过铜制的轴套10e并在穿出端以防松螺母20b固定于两侧间隔部上10b。
本领域技术人员应当能够理解，踏板支架10上轴孔10d内设置的铜制的轴套10e起润滑作用，使踏板20底部的转轴20a(法兰螺栓)在轴孔10d 内转动得更加顺滑灵活。防松螺母20b是以特殊的工程塑料永久的附着在螺纹上，使内外螺纹在缩紧过程中，工程塑料被挤压而产生强大的反作用力，极大地增加了内外螺纹之间的摩擦力，提供了对振动的绝对阻力。转轴20a(法兰螺栓)和防松螺母20b可以采用不锈钢或碳钢发黑或碳钢镀锌等材质的标准件，从而保证它们的强度和耐腐蚀性。
进一步地，踏板20包括枢转地连接于踏板支架10的连接板21(以上述转轴20a设置于连接板21的底部实现枢转)，覆设于连接板21上的防滑板22，防滑板22上形成有凸肋22a，以及覆设于防滑板22上的踩踏板23，踩踏板23上形成有与凸肋22a匹配的贯通槽23a，以使凸肋22a能够穿过贯通槽23a并裸露于踩踏板23的表面。在本实施例中，防滑板22采用橡胶板。
本领域技术人员应当能够理解，防滑板22上的凸肋22a穿过踩踏板23上的贯通槽23a，再由踩踏板23的表面裸露，从而使踩踏板23也具有了防滑、耐磨、减振的功能。在本实施例中，防滑板22采用橡胶板(相应的凸肋22a也为橡胶材质)，能够使驾驶者/操作者踩踏在踩踏板23上后感觉柔软且具有弹性，增加了驾驶者/操作者的舒适性。另外，连接板21的底部可以设置有加强筋，从而提高连接板21的结构强度，确保连接板21能够承受转轴20a(法兰螺栓)的拧紧力矩而不产生变形。在本实施例中，踩踏板23表面采用不锈钢拉丝工艺，既增加耐腐蚀性又比较美观。
进一步地，连接板21、防滑板22和踩踏板23以沉头螺栓24相互固定连接。踩踏板23上形成有沉头孔，以使沉头螺栓24在将上述三者固定连接后，沉头螺栓24的端部能够嵌入至沉头孔内(即沉头螺栓24不会突出于踩踏板23的表面)。
进一步地，结合图5和6所示，踏板支架10和加速开关30固定地设置于一踏板箱40的箱体内(例如焊接)，踏板箱40上形成有开口40a。当踏板20处于枢转高位时，踏板20由开口40a伸出踏板箱40的箱体。当踏板20被施加外力时(例如踩踏)，并被踏板支架10的限位端10a限制旋转时，从踏板箱40的外部观察，踏板20基本与踏板箱40的表面40b齐平。
本领域技术人员应当能够理解，踏板20的最大旋转角度为18°～24°，因此踏板20处于枢转高位时与踏板箱40的表面40b夹角为18°～24°，当踏板20被踩踏直至被踏板支架10的限位端10a限制时，踏板20旋转 18°～24°后呈现与踏板箱40的表面40b齐平的状态。此时，由踏板箱40的外部观察，踏板20的外轮廓与踏板箱40的开口40a的轮廓相重合，二者周边仅留有很小的缝隙。由此，既满足了操作时的舒适感，又使得踏板箱40更为美观、简洁。
参照图2所示，进一步地，踏板箱40包括竖向地设置于箱体内的隔板41，隔板41上设置有安装孔41a。踏板支架10的两侧间隔部10b临近隔板41设置，以使两侧间隔部10b上的轴孔10d与安装孔41a处于同一直线上。转轴20a(法兰螺栓)先穿过隔板41上的安装孔41a，再穿过两侧间隔部10b上的轴孔10d，最后转轴20a(法兰螺栓)的穿出端被防松螺母20b固定。
参照图3～4所示，进一步地，踏板箱40包括设置于箱体内的具有第一销孔44的固定支架42和限位支架43，限位支架43和固定支架42相对地布置，且限位支架43能够朝向或远离固定支架42运动。加速开关30前端的两侧对称地形成有第一销轴30a，以使加速开关30能够经由第一销轴30a转动地连接于固定支架42和限位支架43。
更进一步地，踏板箱40包括设置于箱体内的导向槽45，一定位柱46设置于导向槽45内，限位支架43上具有一长条形的定位孔43a，以使限位支架43经由长条形的定位孔43a能够被套设于定位柱46上，并且能够在导向槽45内运动(朝向或远离固定支架42的方向)。在本实施例中，限位支架43呈“L”形，导向槽45呈“]”形。限位支架43的水平端能够在导向槽45内滑动。
进一步地，加速开关30后端的两侧对称地形成有第二销轴30b，连接板21上形成有第二销孔，以使加速开关30能够经由第二销轴30b与连接板21转动地连接。
在本实施例中，固定支架42和限位支架43可以采用喷塑、电泳、镀锌的碳钢或采用不锈钢，以保证它们的强度和耐腐蚀性。装配加速开关30时，先将限位支架43向着远离固定支架42的一侧滑动，再以加速开关30前端两侧的第一销轴30a对准固定支架42和限位支架43的第一销孔44，最后将限位支架43朝着固定支架42一侧滑动，使第一销轴30a进入第一销孔44，完成对加速开关30的固定。基于此结构，可运动的限位支架43实际上为加速开关30预留了装配余量，精准装配的加速开关30能够更准确地被踏板20控制行程。
另外，如图5和6所示，洗地车200包括了如上所述的任意一种加速踏板组件100。加速踏板组件100可以经由踏板箱40安装于洗地车200的车体210。
