背景技术
车用脚踏板是安装在车辆的底盘上供人们上下车用。车用脚踏板装置的伸缩机构由电机通过减速机驱动。由于车用脚踏板装置的安装空间很有限，因此要求车用脚踏板装置外形尺寸小。现有的车用脚踏板装置的减速机有两类。
第一类减速机是蜗轮蜗杆减速机构+圆柱齿轮减速机构，第一类减速机存在防护等级低、外形尺寸大的缺陷，导致第一类减速机很难被安装在车体上。

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。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参考附图描述根据本发明实施例的车用脚踏板装置10。如图1-图10所示，根据本发明实施例的车用脚踏板装置10包括伸缩机构101、踏板102、电机103、齿轮箱104、蜗轮105、太阳轮1061、行星支架1062、行星轮1063和调节件107。
伸缩机构101包括安装支座1011、踏板支座1012以及连接在安装支座1011与踏板支座1012之间且驱动踏板支座1012在伸出位置与缩回位置之间移动的臂组件1013。踏板102安装在踏板支座1012上，电机103具有构造为蜗杆的电机轴1031。换言之，电机轴1031 的至少一部分上形成有螺旋齿。齿轮箱104内具有容纳腔1041，电机轴1031的至少一部分伸入到容纳腔1041内。调节件107沿电机轴1031的轴向可移动地设在齿轮箱104上，调节件107抵靠在电机轴1031的自由端上。
蜗轮105包括蜗轮本体1051和设在蜗轮本体1051上的输出轴1052，蜗轮105可旋转地设在容纳腔1041内，蜗轮本体1051与电机轴1031啮合。太阳轮1061套设在输出轴1052上。行星支架1062可旋转地设在容纳腔1041内，行星轮1063可旋转地设在行星支架1062上，行星轮1063与太阳轮1061啮合。其中，行星支架1062与臂组件1013相连以驱动臂组件1013，进而驱动踏板支座1012在该伸出位置与该缩回位置之间移动。
下面参考图1-图10描述根据本发明实施例的车用脚踏板装置10的工作过程。当用户不使用车用脚踏板装置10时，踏板支座1012位于该缩回位置。
当用户需要上车或下车时，电机103的电机轴1031顺时针方向旋转(或逆时针方向旋转)，进而带动蜗轮本体1051旋转和设在蜗轮本体1051上的输出轴1052旋转。由于太阳轮1061套设在输出轴1052上，因此太阳轮1061旋转。其中，太阳轮1061、行星轮1063和行星支架1062构成行星减速机构，且动力通过行星支架1062输出。具体地，行星支架1062与臂组件1013相连，以便通过臂组件1013驱动踏板支座1012从该缩回位置移动到该伸出位置。也就是说，踏板102从该缩回位置移动到该伸出位置，以便用户踩踏踏板102上车或下车。
当用户上车或下车后，电机103的电机轴1031逆时针方向旋转(或顺时针方向旋转)，以便使踏板支座1012从该伸出位置移动到该缩回位置。
根据本发明实施例的车用脚踏板装置10通过设置蜗轮蜗杆机构，从而可以具有反向自锁功能，从而对伸缩机构101(踏板组件)起到安全保护作用。
根据本发明实施例的车用脚踏板装置10通过设置行星减速机构，从而不仅能够达到需求的减速比，而且与圆柱齿轮减速机构、蜗轮蜗杆减速机构相比，行星减速机构结构更加紧凑、具有更小的外形尺寸。因此，根据本发明实施例的车用脚踏板装置10更适合在空间狭小的车底安装。
而且，由于电机103的电机轴1031(即蜗杆)的轴向力较大，因此经过一段时间磨损后，电机轴1031的轴向间隙增大，不仅导致传动效率降低，而且增大了换向时的噪音。根据本发明实施例的车用脚踏板装置10通过在齿轮箱104上设置可以沿电机轴1031的轴向移动且抵靠在电机轴1031的自由端上的调节件107，从而可以通过沿电机轴1031的轴向移动调节件107，来调节电机轴1031的轴向间隙。
也就是说，通过沿电机轴1031的轴向移动调节件107，可以消除电机轴1031的轴向间隙，从而提高传动效率、减小换向时的噪音。
因此，根据本发明实施例的车用脚踏板装置10具有传动效率高、换向噪音低、结构紧凑、外形尺寸小、安全性高、可靠性高、寿命长、制造成本低等优点，适合在空间狭小的车底安装。
如图1-图10所示，在本发明的一些实施例中，车用脚踏板装置10包括伸缩机构101、踏板102和电机组件。该电机组件包括电机103、齿轮箱104、蜗轮105、太阳轮1061、行星支架1062、行星轮1063和调节件107。如图4所示，齿轮箱104包括箱体1042、第一盖1043和第二盖1044。箱体1042内具有容纳腔1041，容纳腔1041的相对设置的第一端(下端)和第二端(上端)均敞开。第一盖1043设在箱体1042上，第一盖1043覆盖容纳腔1041的第一端，第二盖1044设在箱体1042上，第二盖1044覆盖容纳腔1041的第二端。其中，箱体1042与第一盖1043之间设有第一密封圈10451，箱体1042与第二盖1044之间设有第二密封圈10452。由此可以使齿轮箱104的结构更加合理。
而且，通过在箱体1042与第一盖1043之间设置第一密封圈10451且在箱体1042与第二盖1044之间设置第二密封圈10452，从而可以提高齿轮箱104的密封性能，以便防止外界的水、沙土等杂质进入到容纳腔1041内，避免设置在容纳腔1041内的零部件受到损坏。
由此可以极大地提高该电机组件的防水性能和防护等级，从而可以提高该电机组件在恶劣环境中的可靠性和使用寿命。其中，该电机组件可以实现IP68防护等级，车用脚踏板装置10及其该电机组件适用于各种恶劣的越野环境，例如河水、泥泞路、野外道路、山路等，扩大了车用脚踏板装置10及其该电机组件的使用范围和使用工况。上下方向如图4中的箭头D所示。其中，图4中标示的上下方向只是为了便于描述而人为设定的上下方向，图4中标示的上下方向不同于现实空间的上下方向。
如图4所示，齿轮箱104进一步包括安装支架1047，安装支架1047包括第一环形部10471和第二环形部10472。第一环形部10471的外沿与容纳腔1041的壁相连，第二环形部10472的下沿与第一环形部10471的内沿相连。具体地，第二环形部10472沿上下方向设置，第一环形部10471垂直于第二环形部10472。
第二环形部10472套设在输出轴1052上，蜗轮本体1051套设在第二环形部10472上。太阳轮1061套设在输出轴1052的位于第一环形部10471和第二环形部10472的下方的部分上。
通过设置安装支架1047，从而可以更加方便地、稳固地安装蜗轮本体1051和输出轴1052上。有利地，箱体1042与安装支架1047一体形成。其中，内外方向如图4中的箭头E所示，
如图4所示，齿轮箱104进一步包括圆形的支撑凸台1048，支撑凸台1048设在第一环形部10471的上表面上，支撑凸台1048的中心轴线与输出轴1052的中心轴线重合，蜗轮 本体1051设在支撑凸台1048上。由此可以减小蜗轮本体1051与第一环形部10471的摩擦面积。
在本发明的一个实施例中，如图4所示，第二环形部10472与输出轴1052之间设有轴承1049。换言之，轴承1049设在第二环形部10472内，轴承1049套设在输出轴1052上。也就是说，第二环形部10472套设在轴承1049上。由此可以极大地减小第二环形部10472与输出轴1052之间的摩擦力。
有利地，第二环形部10472的内周面和轴承1049的外周面中的一个上设有凸起10473，第二环形部10472的内周面和轴承1049的外周面中的另一个上设有第一凹槽，凸起10473配合在该第一凹槽内。
如图4、图9和图10所示，行星支架1062通过连接轴1064与臂组件1013相连。具体而言，第一盖1043上设有通孔10431，行星支架1062的第一部分配合在通孔10431内，行星支架1062的第一部分与通孔10431的壁之间设有第三密封圈10453。其中，行星支架1062的第一部分的下表面上设有容纳孔10621，连接轴1064的端部配合在容纳孔10621内。
而且，通过在行星支架1062的第一部分与通孔10431的壁之间设置第三密封圈10453，从而可以提高齿轮箱104的密封性能，以便防止外界的水、沙土等杂质进入到容纳腔1041内，避免设置在容纳腔1041内的零部件受到损坏。
由此可以极大地提高该电机组件的防水性能和防护等级，从而可以提高该电机组件在恶劣环境中的可靠性和使用寿命。其中，该电机组件可以实现IP68防护等级，车用脚踏板装置10及其该电机组件适用于各种恶劣的越野环境，例如河水、泥泞路、野外道路、山路等，扩大了车用脚踏板装置10及其该电机组件的使用范围和使用工况。
如图4-图8所示，在本发明的一些示例中，齿轮箱104上设有螺纹孔1046，调节件107螺纹配合在螺纹孔1046内。由此当电机轴1031的轴向间隙增大时，可以通过旋转调节件107来使调节件107抵靠在电机轴1031的自由端上，从而可以消除电机轴1031的轴向间隙。
在本发明的一个具体示例中，调节件107的远离电机轴1031的端面上设有第二凹槽1071。由此可以通过使螺丝刀等插入第二凹槽1071内，来旋转调节件107。具体地，调节件107可以是螺母。
如图9和图10所示，车用脚踏板装置10进一步包括弹性件108，弹性件108在电机103驱动踏板支座1012朝向该伸出位置移动时弹性变形以储存能量，弹性件108在电机103驱动踏板支座1012朝向该缩回位置移动时释放能量以协助电机103驱动伸缩机构101。
当电机轴1031沿顺时针方向旋转(或逆时针方向旋转)时，电机轴1031带动弹性件108运动使弹性件108发生弹性形变以储存能量，踏板102由该缩回位置运动至该伸出位 置。
当电机轴1031沿逆时针方向旋转(或顺时针方向旋转)时，弹性件108回复释放能量以协助电机103驱动伸缩机构101缩回，降低了电机103沿逆时针方向旋转(或顺时针方向旋转)时的负载以及工作电流。由此在伸缩机构101的伸出过程和缩回过程中，电机103的工作电流大体一致，有效地保护了电机103，提高了电机103的工作寿命。
更具体地，安装支座1011安装在车辆的车体上，例如安装支座1011安装在车辆的底盘20上。臂组件1013的至少一个臂与安装支座1011可枢转地连接，且臂组件1013的至少一个臂与踏板支座1012可枢转地连接。
连接轴1064与臂组件1013的一个臂连接以驱动臂组件1013运动，进而带动连接在臂组件1013上的踏板支座1012运动。换言之，电机轴1031通过连接轴1064驱动臂组件1013运动。由此电机103分别沿顺时针方向转动和沿逆时针方向转动就能驱动伸缩机构101的伸出和缩回。
进一步地，弹性件108为涡卷弹簧，该涡卷弹簧的第一端1081固定且该涡卷弹簧的第二端1082由电机轴1031驱动扭转。
具体地，如图9和图10所示，弹性件108为涡卷弹簧，该涡卷弹簧的最外圈的端部向外弯折以形成第一端1081，该涡卷弹簧的最内圈的端部向内弯折以形成第二端1082。其中，第一端1081包含该涡卷弹簧的最内圈的端部以及与该端部连接的部分内圈，第二端1082包含该涡卷弹簧的最外圈的端部以及与该端部连接的部分外圈。
当伸缩机构101(即踏板102)伸出时，该涡卷弹簧的第一端1081固定不动，该涡卷弹簧的第二端1082随电机轴1031一起转动并被扭紧以储存能量。当伸缩机构101(即踏板102)缩回时，该涡卷弹簧的第一端1081固定不动，该涡卷弹簧的第二端1082随电机轴1031一起转动以回复释放能量，从而为伸缩机构101的缩回提供助力。此外，弹性件108采用涡卷弹簧，结构简单紧凑，便于安装。
然而，本发明并不限于此，弹性件108还可以是弹片、碟簧，或者其他可以发生弹性形变的零件或部件。此外，本领域技术人员可以根据电机103伸出与缩回时的负载差值，选择合适规格的涡卷弹簧以使涡卷弹簧能够更好地均衡伸出和缩回两个工作过程中的电机103的负载。
如图9和图10所示，在本发明的一个示例中，车用脚踏板装置10还包括连接盘1091和罩盖1092，齿轮箱104的第一盖1043上设有凹部，该凹部由罩盖1092封盖以形成容纳空间，连接盘1091设在该容纳空间内且由电机轴1031驱动旋转。该涡卷弹簧设在该容纳空间内，该涡卷弹簧的第一端1081固定在罩盖1092内，该涡卷弹簧的第二端1082与连接盘1091相连。
具体而言，连接盘1091大体为圆盘形，连接盘1091位于该容纳空间内且连接盘1091的相对的两个端面分别与该凹部和罩盖1092相对，连接盘1091与电机轴1031间接连接(连接盘1091可以与连接轴1064直接相连)以在电机轴1031的带动下转动。该涡卷弹簧外套在连接盘1091上，该涡卷弹簧的第二端1082连接在连接盘1091上并与连接盘1091一起同向转动。
由此，将该涡卷弹簧集成在车用脚踏板装置10的电机组件上，不仅减少了传动损耗，而且使车用脚踏板装置10整体结构更紧凑。
如图9和图10所示，在一些实施例中，罩盖1092可拆卸地扣合到齿轮箱104的第一盖1043上，安装支座1011上设有限位柱10111，罩盖1092上设有限位凹口10921，限位柱10111配合在限位凹口10921内以将罩盖1092安装到安装支座1011上，该涡卷弹簧的第一端1081套在限位柱10111上。
参照图9和图10，齿轮箱104的第一盖1043的朝向安装支座1011的端面上设有该凹部，罩盖1092包括端盖以及连接在该端盖边沿的凸缘，该凸缘的内壁具有阶梯定位面，罩盖1092通过该阶梯定位面封盖在该凹部上。限位凹口10921为自罩盖1092的边沿向内延伸的缺口，安装支座1011上与齿轮箱104相对的侧面上设有限位柱10111，限位柱10111上设有与限位凹口10921配合的卡口，两个限位柱10111的卡口的底面将罩盖1092抵在齿轮箱104的第一盖1043上以对罩盖1092施加轴向限位，且两个限位柱10111的卡口的侧面对罩盖1092进行径向和周向限位，该涡卷弹簧的第二端1082经限位凹口10921伸出且套在限位柱10111上。
由此，罩盖1092、齿轮箱104的第一盖1043、安装支座1011固定连接在一起，且为该涡卷弹簧的第二端1082的固定提供了合适的位置，减少该涡卷弹簧安装以及使用时发生扭转变形。
可以理解，罩盖1092、连接盘1091、该凹部的形状可以是圆形、椭圆形等，限位凹口10921以及限位柱10111的数量不限于两个，限位凹口10921的数量大于两个时，多个限位凹口10921可沿罩盖1092的周向均布。
优选地，连接盘1091的外周面上设有卡槽10911，该涡卷弹簧的第二端1082插入配合在卡槽10911内。
参照图9和图10，卡槽10911自连接盘1091的外边沿向内延伸且卡槽10911的延伸方向沿连接盘1091的径向，连接盘1091以及连接轴1064的中心具有花键孔，连接轴1064具有外花键，连接轴1064与臂组件1013中的一个臂连接且连接轴1064穿过安装支座1011。由此，电机轴1031带动连接轴1064以及连接盘1091转动，固定在连接盘1091上的该涡卷弹簧的第二端1082随连接盘1091一起转动，从而使该涡卷弹簧逐渐被旋紧，结构简单、 紧凑。此外，采用花键连接方式既便于拆装又能保证动力传动。
如图9和图10所示，根据本发明的一个实施例，齿轮箱104的第一盖1043上设有安装孔10432，限位柱10111穿过安装孔10432，限位柱10111内具有螺纹孔，齿轮箱104通过配合到该螺纹孔内的螺栓1093安装到安装支座1011上。其中，限位柱10111穿过限位凹口10921并止抵在齿轮箱104的第一盖1043上，齿轮箱104的第一盖1043上的安装孔10432与限位柱10111内的螺纹孔一一对应，螺栓1093穿过安装孔10432并旋入该螺纹孔内以将齿轮箱104的第一盖1043固定到安装支座1011上。采用螺栓1093连接方式将齿轮箱104的第一盖1043与连接盘1091、安装支座1011固定到一起，可以方便涡卷弹簧的维修更换。
然而，本发明并不限于此，齿轮箱104的第一盖1043、连接盘1091、安装支座1011之间还可以通过焊接等其他任何合适的方式固定。
本发明还提供了一种车用脚踏板装置10的电机组件。如图1-图10所示，根据本发明实施例的车用脚踏板装置10的电机组件包括电机103、齿轮箱104、蜗轮105、太阳轮1061、行星支架1062、行星轮1063和调节件107。
电机103具有构造为蜗杆的电机轴1031。齿轮箱104内具有容纳腔1041，电机轴1031的至少一部分伸入到容纳腔1041内。调节件107沿电机轴1031的轴向可移动地设在齿轮箱104上，调节件107抵靠在电机轴1031的自由端上。
蜗轮105包括蜗轮本体1051和设在蜗轮本体1051上的输出轴1052，蜗轮105可旋转地设在容纳腔1041内，蜗轮本体1051与电机轴1031啮合。太阳轮1061套设在输出轴1052上。行星支架1062可旋转地设在容纳腔1041内，行星轮1063可旋转地设在行星支架1062上，行星轮1063与太阳轮1061啮合。其中，行星支架1062与臂组件1013相连以驱动臂组件1013。
根据本发明实施例的车用脚踏板装置10的电机组件具有传动效率高、换向噪音低、结构紧凑、外形尺寸小、安全性高、可靠性高、寿命长、制造成本低等优点，适合在空间狭小的车底安装。
