浮动螺母组件广泛应用于汽车工业中，例如，浮动螺母组件可用于将汽车部件(诸如电池)固定于车身上。现有的浮动螺母组件包括限位盒和螺母，限位盒限定位于其内部的腔，螺母被限制于限位盒内。螺母能够在限位盒内移动，以实现螺母的浮动。发明人注意到，浮动螺母组件在与螺栓装配时，装配效率较低，并且装配精度较低。发明人研究发现，导致装配效率较低及装配精度较低的原因在于，螺母在限位盒内的移动空间较大，也即，螺母的浮动空间较大。螺母在限位盒内的移动空间较大，导致螺栓在与螺母配合时，螺母容易发生位置偏移，浪费装配时间，并且影响装配精度。
鉴于此，发明人经过深入研究，设计了一种浮动螺母组件，通过限位支架与底座可拆卸地连接，在限位支架与底座之间形成用于容纳螺母的限位空间，螺母被限制于限位空间内，在限位支架和螺母中的一者上设置有至少两个凸起，另一者上设置有至少两个定位孔，凸起与定位孔一一对应，凸起插设于定位孔内，凸起与定位孔间隙配合和/或弹性配合。
在这样的浮动螺母组件中，限位支架与底座连接后，通过限位支架与底座之间形成的限位空间容纳螺母，以将螺母限制于限位空间内。在凸起与定位孔间隙配合的实施例中，螺母能够相对于限位支架在垂直于螺纹孔的轴向的平面内移动，以实现螺母的浮动；在凸起与定位孔弹性配合的实施例中，基于弹性特性，螺母能够相对于限位支架在垂直于螺纹孔的轴向的平面内移动，以实现螺母的浮动；在凸起与定位孔间隙配合和弹性配合的实施例中，螺母能够相对于限位支架在垂直于螺纹孔的轴向的平面内移动，并且移动范围较大，以实现螺母的浮动。当螺母相对于限位支架在垂直于螺纹孔的轴向的平面内移动时，由于凸起与定位孔的配合，使得螺母的浮动空间较小，也即在螺母与螺栓的装配过程中螺母的移动量较小，以保证螺母与螺栓的装配效率及连接精度。同时，至少两个凸起与至少两个定位孔对应，能够防止螺母相对于限位支架转动，进一步保证螺母与螺栓的装配效率及连接精度。
本申请实施例公开的用电设备可以为但不限于车辆、船舶或飞行器等用电设备。以下实施例为了方便说明，以本申请一实施例的一种用电设备为车辆为例进行介绍。
在车辆的装配过程中，电池安装于车身的底部，电池通过浮动螺母组件与螺栓的配合方式固定于车身梁，以便于电池的装配与拆卸。
参见图1，图1为根据本申请一些实施例的浮动螺母组件100的分解图，图2为根据本申请一些实施例的浮动螺母组件100的剖视图一，图3为根据本申请一些实施例的浮动螺母组件100的剖视图二。根据本申请的一些实施例，如图1-图3所示，本申请提供了一种浮动螺母组件100，浮动螺母组件100包括螺母10及限位支架20。 螺母10开设有螺纹孔11。限位支架20用于与底座500可拆卸地连接，在限位支架20与底座500之间形成用于容纳螺母10的限位空间。限位支架20与螺母10中的一者上设置有至少两个凸起31，另一者上设置有至少两个定位孔32，凸起31与定位孔32一一对应，凸起31插设于定位孔32，凸起31与定位孔32间隙配合和/或弹性配合。
底座500为浮动螺母组件100的安装基础。限位支架20为用于限制螺母10的位置部件。当浮动螺母组件100用于汽车部件的装配时，底座500可以为车辆的车身梁。限位支架20与底座500连接后，螺母10收容于限位空间内，螺母10被限制在限位空间内。螺母10为用于与螺栓连接的部件，以实现待连接的两个部件的快速装配。
可选地，如图2所示，限位支架20与底座500可以通过螺钉40连接，便于装配与拆卸。在一些实施例中，限位支架20与底座500的连接方式可以为卡接、插接等。
限位支架20与螺母10中的一者上设置有至少两个凸起31，另一者上设置有两个定位孔32，可以为两种形式，例如，限位支架20上设置有至少两个凸起31，螺母10上设置有至少两个定位孔32；或者，限位支架20上设置有至少两个定位孔32，螺母10上设置有至少两个凸起31。
图中，凸起31的延伸方向与螺纹孔11的轴向平行。
凸起31与定位孔32一一对应，也即，每个凸起31插入一个定位孔32内。凸起31与定位孔32间隙配合和/或弹性配合，可以为多种形式，例如，凸起31与定位孔32间隙配合，或者，凸起31与定位孔32弹性配合，又或者，凸起31与定位孔32间隙配合和弹性配合。
在凸起31与定位孔32间隙配合的实施例中，螺母10能够相对于限位支架20在垂直于螺纹孔11的轴向的平面内移动，以实现螺母10的浮动；在凸起31与定位孔32弹性配合的实施例中，基于弹性特性，螺母10能够相对于限位支架20在垂直于螺纹孔11的轴向的平面内移动，以实现螺母10的浮动；在凸起31与定位孔32间隙配合和弹性配合的实施例中，螺母10能够相对于限位支架20在垂直于螺纹孔11的轴向的平面内移动，并且移动范围较大，以实现螺母10的浮动。
根据本申请实施例的浮动螺母组件100，通过限位支架20和底座500之间形成的限位空间容纳螺母10，以将螺母10限制于限位空间内；通过凸起31与定位孔32之间的间隙配合和/或弹性配合，能够实现螺母10相对于限位支架20的浮动，当螺母10相对于限位支架20在垂直于螺纹孔11的轴向的平面内移动时，由于凸起31与定位孔32配合，使得螺母10的浮动空间较小，也即在螺母10与螺栓的装配过程中螺母10的移动量较小，以保证螺母10与螺栓的装配效率及连接精度。同时，至少两个凸起31与至少两个定位孔32对应，能够防止螺母10相对于限位支架20转动，进一步保证螺母10与螺栓的装配效率及连接精度。
需要指出的是，定位孔32的横截面可以为但不限于圆形，还可以为矩形等规则图形，只要能够满足凸起31和定位孔32配合后，螺母10能够相对于限位支架20在垂直于螺纹孔11的轴向的平面内移动即可。对应的，凸起31的横截面可以与定位孔32的横截面轮廓匹配，也即，凸起31的外周面各处到定位孔32的孔壁的距离相等。
为了便于描述，本申请以下实施例以定位孔32为圆形孔，凸起31为柱状结构 为例进行介绍。为了保证螺母10在垂直于螺纹孔11的轴向的平面内各方向的移动量相同，定位孔32的轴线与凸起31的轴线共线。
根据本申请的一些实施例，可选地，凸起31与定位孔32弹性配合，凸起31被配置为能够在其径向上发生弹性变形。
凸起31可以为柱状结构，凸起31的延伸方向平行于螺纹孔11的轴向；凸起31的径向是指在垂直于凸起31的延伸方向的平面(也即垂直于螺纹孔11的进行的平面)内，经过凸起31的轴线的方向。凸起31的径向垂直于螺纹孔11的轴向。
凸起31与定位孔32弹性配合，是指凸起31和定位孔32的孔壁中至少一者受力后发生形变，以允许螺母10相对于限位支架20在受力方向上产生位置移动，也即，螺母10相对于限位支架20在垂直于螺纹孔11的轴向的平面内移动。凸起31与定位孔32弹性配合，可以为凸起31能够在其径向上发生弹性形变，或者，也可以为定位孔32的孔壁能够在定位孔32的径向上发生弹性形变，又或者，还可以为凸起31能够在凸起31的径向上发生弹性形变并且定位孔32的孔壁能够在定位孔32的径向上发生弹性形变。在一些实施例中，凸起31被配置为能够在其径向上发生弹性变形，以允许螺母10相对于限位支架20在垂直于螺纹孔11的轴向的平面内产生位置移动。
通过凸起31在其径向上的弹性形变，以便于螺母10相对于限位支架20移动，实现螺母10的浮动。
根据本申请的一些实施例，可选地，至少两个凸起31绕螺母10的轴线间隔分布。
螺母10的轴线为螺纹孔11的轴线。至少两个凸起31绕螺母10的轴线间隔分布，是指所有的凸起31围绕螺母10的轴线设置。凸起31与定位孔32一一对应，至少两个凸起31绕螺母10的轴线间隔分布，对应地，至少两个定位孔32绕螺母10的轴线间隔分布。换句话说，所有的定位孔32围绕螺母10的轴线设置。例如，图4为根据本申请一些实施例的限位支架20的结构示意图(仰视方向)，在定位孔32设置于螺母10的实施例中，如图4所示，定位孔32的数量为四个，四个定位孔32绕螺母10的轴线间隔分布。
所有的凸起31绕螺母10的轴线间隔设置，使得螺母10与限位支架20配合稳定，保证螺母10在垂直于螺母10的轴线的平面内任意方向均能够相对于限位支架20移动，满足螺母10的浮动需求。
根据本申请的一些实施例，可选地，凸起31与定位孔32接触的部分由弹性材料制成。
凸起31插设于定位孔32内，凸起31与定位孔32接触是指凸起31的外周面与定位孔32的孔壁接触。凸起31与定位孔32接触的部分由弹性材料制成，是指凸起31的外周面由弹性材料制成，也即，凸起31的用于与定位孔32的孔壁接触的表面由弹性材料制成。在凸起31的外周面由弹性材料制成的情况下，当凸起31与定位孔32接触时，随着凸起31的外周面与定位孔32的孔壁的抵接受力，凸起31的外周面能够在凸起31的径向上发生弹性形变，以使得螺母10能够相对于限位支架20在垂直螺纹孔11的轴向的平面内移动。
当凸起31为复合式结构时，凸起31包括基体和弹性材料层，弹性材料层套设于基体的外周面，基体可以由刚性材料制成，弹性材料层用于与定位孔32的孔壁接触。当凸起31为一体式结构时，凸起31整体可以由弹性材料制成。
凸起31的用于与定位孔32接触的部分由弹性材料制成，以便于凸起31的与定位孔32接触的部分发生弹性形变，满足螺母10相对于限位支架20移动的需求，实现螺母10的浮动。
根据本申请的一些实施例，可选地，定位孔32的孔壁由弹性材料制成，例如定位孔32的孔壁设置有弹性层。当凸起31与定位孔32接触且对定位孔32的孔壁施加作用力时，设置于孔壁的弹性层受力发生形变，从而允许螺母10相对于限位支架20移动一定的距离，实现螺母10的浮动。
根据本申请的一些实施例，可选地，如图4所示，凸起31可以包括多个子凸起311，多个子凸起311绕凸起31的轴线间隔设置。
每个子凸起311沿凸起31的延伸方向设置，每个子凸起311的一端为自由端，使得子凸起311为悬臂结构。当定位孔32的孔壁抵接于子凸起311时，随着子凸起311的受力增加，子凸起311在凸起31的径向上发生形变，从而使得螺母10相对于限位支架20浮动。例如，在凸起31设置在限位支架20、定位孔32设置在螺母10的实施例中，子凸起311的一端连接于限位支架20，子凸起311的另一端为自由端。
需要指出的是，在凸起31与定位孔32弹性配合的实施例中，定位孔32可以为盲孔，也可以为通孔。
图5为根据本申请一些实施例的凸起31与定位孔32间隙配合示意图。根据本申请的一些实施例，可选地，如图5所示，凸起31与定位孔32间隙配合，凸起31穿过定位孔32，凸起31的端部设置有弹性阻挡件33，弹性阻挡件33用于限制凸起31沿定位孔32的轴向从定位孔32中脱离。
凸起31穿过定位孔32，定位孔32为贯穿限位支架20或螺母10的通孔。例如，图6为根据本申请另一些实施例的限位支架20的结构示意图(仰视方向)，在凸起31设置于限位支架20、定位孔32设置于螺母10的实施例中，如图5和图6所示，定位孔32沿螺纹孔11的轴向贯穿螺母10，凸起31的一端连接于限位支架20，弹性阻挡件33位于凸起31的远离限位支架20的一端，弹性阻挡件33位于定位孔32外，弹性阻挡件33与限位支架20位于定位孔32的两侧。又例如，在凸起31设置于螺母10、定位孔32设置于限位支架20的实施例中，定位孔32沿螺纹孔11的轴向贯穿限位支架20，凸起31的一端连接于螺母10，弹性阻挡件33位于凸起31的远离螺母10的一端，弹性阻挡件33位于定位孔32外，弹性阻挡件33与限位支架20位于定位孔32的两侧。
弹性阻挡件33的尺寸大于定位孔32的直径，从而阻挡凸起31沿定位孔32的轴向从定位孔32中脱离。
凸起31与定位孔32间隙配合，以满足螺母10的浮动需求。通过在凸起31的端部设置弹性阻挡件33，在凸起31与定位孔32配合后，弹性阻挡件33能够限制凸起31沿定位孔32的轴向从定位孔32中脱离，保证浮动螺母组件100在移动过程中限位 支架20和螺母10组合在一起，避免部件遗失。
根据本申请的一些实施例，可选地，如图5和图6所示，弹性阻挡件33套设于凸起31，弹性阻挡件33的外周面包括第一导向斜面331和第二导向斜面332，第一导向斜面331与第二导向斜面332沿定位孔32的轴向相对设置。

弹性阻挡件33的外周面为弹性阻挡件33的绕凸起31的轴线的面。弹性阻挡件33包括第一导向斜面331和第二导向斜面332，第一导向斜面331与第二导向斜面332沿定位孔32的轴向相对设置，第一导向斜面331与第二导向斜面332之间形成夹角，夹角指向背离凸起31的轴线的方向。
在凸起31设置于限位支架20的实施例中，第一导向斜面331相对于第二导向斜面332远离限位支架20，第一导向斜面331和第二导向斜面332的导向功能具体为：在凸起31插入定位孔32的过程中，当第一导向斜面331与定位孔32的端部接触时，第一导向斜面331先与定位孔32的孔壁接触，随着凸起31沿定位孔32的轴向朝向定位孔32移动，弹性阻挡件33发生弹性形变，第一导向斜面331与定位孔32的孔壁的接触面积逐渐增大，直至弹性阻挡件33完全位于定位孔32内；凸起31继续沿着定位孔32的轴向移动，弹性阻挡件33逐渐离开定位孔32，直至弹性阻挡件33完全位于定位孔32外，实现凸起31插入定位孔32。在凸起31脱离定位孔32的过程中，第二导向斜面332先与定位孔32的孔壁接触，随着凸起31沿定位孔32的轴向移动，弹性阻挡件33发生弹性形变，第二导向斜面332与定位孔32的孔壁的接触面积逐渐增大，直至弹性阻挡件33完全位于定位孔32内；凸起31继续沿着定位孔32的轴向移动，弹性阻挡件33移动至定位孔32的靠近限位支架20的一端并逐渐离开定位孔32，当弹性阻挡件33完全离开定位孔32后，凸起31与定位孔32脱离。
通过第一导向斜面331和第二导向斜面332的导向功能，能够便于弹性阻挡件33从定位孔32的轴向两端进入定位孔32，提高了装配和维修效率。另一方面，第一导向斜面331和第二导向斜面332的导向功能，减小了弹性阻挡件33进入定位孔32的阻力，能够提高弹性阻挡件33的使用寿命，避免弹性阻挡件33进入定位孔32的阻力过大而导致弹性阻挡件33损坏。
根据本申请的一些实施例，可选地，凸起31的端部和/或定位孔32的端部设置有用于引导凸起31插入定位孔32的导向部。
凸起31端部和/或定位孔32的端部设置有导向部，是指：凸起31的端部可以设置有导向部，或者，定位孔32的端部可以设置有导向部，又或者，凸起31的端部和定位孔32的端部可以均设置有导向部。导向部可以为倒角，起到导向的功能，以引导凸起31插入定位孔32，减小凸起31进入定位孔32的难度。
通过导向部的导向功能，便于凸起31插入定位孔32内，便于实现限位支架20与螺母10的装配。

可选地，支架本体21可以为平板，结构简单。
通过支架本体21与底座500形成限位空间，以将螺母10限制于限位空间内，结构简单。通过连接臂22与底座500可拆卸地连接，以便于实现螺母10的装配与更换。

连接臂22的投影与支架本体21的投影不重叠，也即，连接臂22的一端连接于支架本体21的端部。
在垂直于螺纹孔11的轴向的平面内，连接臂22的投影不重叠，使得螺母10与限位支架20能够沿螺纹孔11的轴向相互分离，便于实现螺母10的更换。
根据本申请的一些实施例，可选地，如图4和图6所示，连接臂22包括第一段221和第二段222，第一段221与支架本体21的边缘连接，第二段222从第一段221沿螺纹孔11的径向朝向背离螺纹孔11的轴线的方向延伸，第一段221与第二段222之间具有夹角，第二段222用于与底座500可拆卸地连接。

第一段221与第二段222之间的夹角可以为直角，也可以为钝角。例如，如图所示，第一段221与第二段222构成L字形结构。
可选地，如图2、图4和图6所示，第二段222设置有带螺纹的连接孔，第二段222与底座500通过螺钉40连接。
第二段222从第一段221沿螺纹孔11的径向朝向背离螺纹孔11的轴线的方向延伸，使得连接臂22的投影与支架本体21的投影不重叠，连接臂22不占用支架本体21与螺母10之间的空间，便于保证浮动螺母组件100结构紧凑。
图7为根据本申请一些实施例的螺母的结构示意图，图8为根据本申请一些实施例的限位支架与螺母的配合示意图。根据本申请的一些实施例，可选地，如图7和图8所示，螺母10包括螺母本体12和凸缘13，螺纹孔11设置于螺母本体12，凸缘13形成于螺母本体12的外周面。支架本体21上开设有与螺母本体12对应的通孔211，支架本体21通过通孔211套设于螺母本体12，凸缘13被限位在限位空间内。请再参见图1，凸起31设置在支架本体21上，定位孔32设置在凸缘13上。
通孔211的轴线方向与螺母10的轴线方向一致。
凸缘13形成于螺母本体12的外周面，可以为凸缘13绕螺纹孔11的轴线设置。凸缘13被限定在限位空间内，是指凸缘13的尺寸大于通孔211的尺寸，沿螺纹孔11的轴向，凸缘13无法从通孔211离开限位空间，凸缘13被支架本体21和底座500限位。换句话说，在垂直于螺纹孔11的轴向的平面内，凸缘13的投影大于通孔211的投影，并且凸缘13的投影覆盖通孔211的投影。
在一些实施例中，凸起31还可以设置在凸缘13上，定位孔32还可以设置在支架本体21上。
凸缘13被限位在限位空间内，并且凸缘13能够沿螺母10的轴线方向在限位空间内移动，由于支架本体21通过通孔211套设于螺母本体12，当凸缘13沿螺母10的轴线方向在限位空间内移动时，螺母本体12沿螺母10的轴线方向在通孔211内移动，支架本体21和底座500限制凸缘13沿螺母10的轴线方向离开限位空间，结合凸起31与定位孔32的配合，满足螺母10与限位支架20的装配需求。

避空部131的设置，一方面，避让连接臂22，减少浮动螺母组件100的整体尺寸，减少安装空间占用；另一方面，能够防止螺母10相对于限位支架20转动。
根据本申请的一些实施例，可选地，避空部131为U形结构。避空部131可以位于凸缘13的边缘，以减少凸缘13的尺寸，减少凸缘13的空间占用，从而使得浮动螺母组件100的整体结构紧凑。

限位支架20包括支架本体21和连接臂22，连接臂22连接于支架本体21的边缘，连接臂22用于与底座500可拆卸地连接，支架本体21与底座500之间形成用于容纳螺母10的限位空间。支架本体21设置有通孔211。支架本体21设置有四个凸起31，四个凸起31绕通孔211的轴线间隔分布。连接臂22的数量为两个，两个连接臂22关于通孔211的轴线对称设置。
螺母10包括螺母本体12和凸缘13，螺母本体12设置有螺纹孔11，凸缘13形成于螺母本体12的外周面，凸缘13上设置有四个定位孔32，四个定位孔32绕螺母10的轴线间隔分布。螺纹孔11的轴向为螺母10的轴线方向。
如图2和图3所示，螺母10收纳于限位空间内，凸缘13位于支架本体21和底座500之间，支架本体21通过通孔211套设于螺母本体12，通孔211的轴线与螺母10的轴线共线。凸起31与定位孔32一一对应，凸起31插设于定位孔32内。凸起31与定位孔32弹性配合，凸起31被配置为能够在其径向上发生弹性形变。螺母10能够相对于限位支架20在垂直于螺纹孔11的轴向的平面内移动。
通过限位支架20和底座500之间形成的限位空间容纳螺母10，以将螺母10限制于限位空间内；通过凸起31与定位孔32之间的弹性配合，能够实现螺母10相对于限位支架20浮动，当螺母10相对于限位支架20在垂直于螺纹孔11的轴向的平面内移动时，由于凸起31与定位孔32配合，使得螺母10的浮动空间较小，也即在螺母10与螺栓600的装配过程中螺母10的移动量较小，以保证螺母10与螺栓600的装配效率及连接精度。同时，四个凸起31与四个定位孔32对应，能够防止螺母10相对于限位支架20转动，进一步保证螺母10与螺栓600的装配效率及连接精度。
虽然已经参考优选实施例对本申请进行了描述，但在不脱离本申请的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本申请并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
