下面结合附图和实施例对本申请的实施方式作进一步详细描述。以下实施例的详细描述和附图用于示例性地说明本申请的原理，但不能用来限制本申请的范围，即本申请不限于所描述的实施例。

本申请中，电池单体可以包括锂离子二次电池、锂离子一次电池、锂硫电池、钠锂离子电池、钠离子电池或镁离子电池等，本申请实施例对此并不限定。电池单体可呈圆柱体、扁平体、长方体或其它形状等，本申请实施例对此也不限定。电池单体一般按封装的方式分成三种：柱形电池单体、方体方形电池单体和软包电池单体，本申请实施例对此也不限定。
本申请的实施例所提到的电池是指包括一个或多个电池单体以提供更高的电压和容量的单一的物理模块。例如，本申请中所提到的电池可以包括电池模块或电池包等。电池一般包括用于封装一个或多个电池单体的箱体。箱体可以避免液体或其他异物影响电池单体的充电或放电。

根据本申请的一些实施例，请一并参照图5至图7。本申请提供一种转运装置，转运装置包括机架1、定位组件2、转动调整组件3和夹具组件4，定位组件2用于获取待转运电池100的位置信息；转动调整组件3包括第一驱动件31、相啮合的第一齿轮32和第二齿轮33，第一齿轮32与第一驱动件31连接，第二齿轮33与机架1可转动连接；夹具组件4用于抓取或释放待转运电池100，夹具组件4与第二齿轮33远离机架1的一侧连接，第一驱动件31用于根据位置信息驱动第一齿轮32转动，以使第一齿轮32带动第二齿轮33和夹具组件4转动。
机架1远离夹具组件4的一侧可以与桁架连接，以通过桁架驱动机架1在A区域和B区域之间移动，实现电池转运。A区域和B区域具体可以是具有待换取电池的车辆所在区域、二次电池可进行充电的区域、电池加工区域、电池贮藏区域等。本领域技术人员可以理解的是，桁架可以驱动机架1在水平内沿图6所示X轴方向或Y轴方向，还可以驱动机架1沿竖直方向Z移动。
定位组件2用于获取待转运电池100的位置信息，定位组件2具体可以通过声波定位、红外定位、取景定位等技术获取待转运电池100的位置信息。定位组件2采用超声波定位技术获取位置信息时，定位组件2可以包括多个超声波接收器，待转运电池100中的超声波发射器按照一定的时间间隔发送超声波脉冲，多个超声波接收器分别接收超声波发射器发出来的脉冲信号，根据不同超声波接收器收到信号的时间先后，确定待转运电池100的位置信息。定位组件2采用红外定位获取位置信息时，定位组件2可以包括红外发射器和红外接收器，红外发射器向外发送红外扫描信号，红外扫描信号遇到待转运电池100进行反射，红外接收器接收反射信号并根据反射信号可以获取位置信息。对待转运电池100的定位方式多种多样，本领域技术人员可以采用现有定位技术实现获取待转运电池100的位置信息，在此不再一一赘述。
转动调整组件3可以通过转动夹具组件4，调节夹具组件4和待转运电池100的相对位置关系。第一驱动件31可以是固定在机架1上的伺服电机，第一驱动件31的输出轴与第一齿轮32连接，从而驱动第一齿轮32转动。由于第一齿轮32和第二齿轮33啮合，第一齿轮32转动可带动第二齿轮33转动。第二齿轮33与夹具组件4连 接，所以第一齿轮32转动可以带动第二齿轮33和夹具组件4一并沿第二齿轮32的中心轴转动。第一齿轮32和/或第二齿轮33的数量可以为多个，以实现N层齿轮传动构造。可以是多个第一齿轮32之间依次啮合连接，再通过一个或多个第一齿轮32与第二齿轮33啮合；还可以是多个第一齿轮32分别与第二齿轮33啮合。本领域技术人员可以根据不同传动比变化需求，设置第一齿轮32和第二齿轮33的个数，以及传动的次序。
在本申请中，通过设置定位组件2获取待转运电池100的位置信息，使得转动调整组件3可以根据位置信息调整夹具组件4和待转运电池100的位置关系，使得转运装置更智能；通过设置第一驱动件31、第一齿轮32和第二齿轮33，从而可以通过第一驱动件31驱动第一齿轮32转动，以使第一齿轮32带动第二齿轮33和夹具组件4转动，夹具组件4和待转运电池100沿竖直方向可以准确对应，提高夹具组件4成功拿取待转运电池100的机率，提高转运效率。
第一齿轮32可以为外齿轮，第二齿轮33可以为具有安装孔34的内齿轮，外齿轮设置于安装孔34内并与内齿轮啮合。可选地，内齿轮的中心轴和安装孔34的中心轴可以在同一直线上，外齿轮和内齿轮的中心轴可以不在同一直线上，即内齿轮的中心轴偏离外齿轮和安装孔34的中心轴，外齿轮的分度圆与内齿轮的分度圆相内切。
设置内齿轮与外齿轮啮合，使得第一齿轮32的中心轴和第二齿轮33的中心轴的间隔距离缩短，转动调整组件3更为紧凑，空间利用率高，整体体积变小。
在一些实施例中，定位组件2包括与机架1连接的摄像头21，摄像头21配置为获取待转运电池100的图像，并根据图像生成位置信息并发送给转动调整组件3；转动调整组件3被配置为根据位置信息控制第一驱动件31。例如摄像头21拍摄包含待转运电池100的图像，对图像中预设标志物进行识别，并根据该预设标志物在图像中的坐标生成待转运电池100的位置信息。当然根据图像生成位置信息的方式多种，本领域技术人员可以根据需要选择合适的方法分析计算得到，在此不再赘述。
位置信息可以是待转运电池100基于世界坐标系的位置坐标，也可以是基于待转运电池100与夹具组件4的相对坐标系得到的角度偏差值和水平偏差值。当位置信息包括角度偏差值和水平偏差值的情况下，角度偏差值大于第一预设偏差值，则第一驱动件31转动，以使得在夹具组件4在高度不发生变化的基础上进行转动，直至角度偏差值小于第一预设偏差值；水平偏差值大于第二预设偏差值，则可以通过桁架移动机架1，使得夹具组件4在高度不发生变化的基础上沿X轴方向和/或Y轴方向进行移动，直至水平偏差值小于第二预设偏差值，从而保证夹具组件4和待转运电池100在竖直方向上可以准确对应。其中第一预设偏差值和第二预设偏差值为本领域技术人员预先设置的数值。
通过设置摄像头21，从而可以对待转运电池100进行视觉定位，提高夹具组件4和待转运电池100在竖直方向上对应的准确性。
摄像头21可以设置在第二齿轮33的安装孔34内，从而避免第二齿轮33阻挡摄像头21的取景。同时在一些实施例中，由于第一齿轮32的中心轴偏离第二齿轮33和安装孔34的中心轴设置，使得第一齿轮32在安装孔34中的运动轨迹绕安装孔34的中心轴移动，摄像头21可以沿安装孔34的中心轴设置，从而避免摄像头21和第一齿轮32发生干涉。当然摄像头21也可以设置在第二齿轮33远离夹具组件4的一侧，环境光穿过安装孔34进入摄像头21的取景器内。
请参阅图8至图10，在一些实施例中，夹具组件4包括与第二齿轮33连接的基座41、两个间隔设置的卡合件42、以及设于基座41上的驱动部件43，驱动部件43用于驱动两卡合件42相互靠近或远离以在闭合位置和夹持位置之间切换。
两个卡合件42相互靠近运动至闭合位置，两个卡合件42占用的位置较小，方便插入待转运电池100的箱体中；夹具组件4沿竖直方向下落后，卡合件42移动至待转运电池100的箱体内，驱动部件43驱动卡合件42运动，以使得两个卡合件42远离并运动至夹持位置，此时两个卡合件42占用的位置较大，两个卡合件42的端部可以与待转运电池100的两相对设置的侧板50抵接，或者两个卡合件42可以与待转运电池100中预先设置的卡合结构卡合，例如与支架40的横梁，实现夹具组件4夹取待转运电池100。所以通过驱动部件43驱动两卡合件42相互靠近或远离可以实现对待转运电池100的取放。
驱动部件43包括沿第一方向往复移动的第二驱动件431，卡合件42包括卡爪421和连杆422，连杆422的相对两端分别与第二驱动件431和卡爪421转动连接；第二驱动件431通过两个连杆422分别驱动两个卡爪421沿第二方向相互靠近或远离，第一方向和第二方向相交设置。设置第二驱动件431分别与两个连杆422转动连接，从而可以通过一个第二驱动件431单向移动，实现两个卡爪421相互靠近或远离。
驱动部件43还包括设于基座41上的导轨432和沿导轨432移动的安装座433，导轨432沿第一方向设置，第二驱动件431驱动安装座433沿导轨432移动，连杆422的第一端422a与安装座433转动连接，连杆422的第二端422b与卡爪421转动连接。第二驱动件431推动安装座433沿第一方向向靠近卡爪421方向移动时，第一端422a与安装座433一并沿第一方向向靠近卡爪421方向移动，两个连杆422的第二端422b分别推动两个卡爪421沿第二方向相互远离；第二驱动件431推动安装座433沿第一方向向远离卡爪421方向移动时，第一端422a与安装座433一并沿第一方向向远离卡爪421方向移动，两个连杆422的第二端422b分别拉动两个卡爪421沿第二方向相互远离。设置导轨432可以限制驱动部件43沿第一方向移动连杆422.
在基座41上还可以设置导向结构以限制卡爪421沿第二方向移动。在一些实施例中，基座41具有沿第二方向设置的导向槽，卡爪421卡合于导向槽内并能够沿导向槽移动。通过设置导向槽限制卡爪421沿第二方向移动。
夹具组件4的数量为多个，多个夹具组件4沿第一方向依次间隔设置。在图8所示实施例中，夹具组件4的数量两个，两个夹具组件4以第二齿轮33的中心轴对称 设置。多个夹具组件4可提高转运装置可负载的重量，同时增加夹具组件4夹取待转运电池100时，夹具组件4对待转运电池100的着力点，提高待转运电池100转运过程中的稳定性。当然本领域技术人员可以根据待转运电池100的重量和体积设置合适数量的夹具组件4。
夹具组件4还包括与基座41连接的多个导向件44，导向件44远离夹具组件4中心的表面为斜面。导向件44可以设置于基座41的边沿，多个导向件44分别设置于基座41的不同侧边。夹具组件4移动至箱体的过程中，导向件44的斜面可以与箱体接触，从而引导夹具组件4移动至箱体内。所以设置多个导向件44，有利于夹具组件4移动至箱体内，提高夹具组件4夹取待转运电池的效率。
在一些实施例中，转运装置还包括水平行走机构和升降机构，水平行走机构能够驱动机架1沿水平方向移动，升降机构能够驱动机架1沿竖直方向移动。
转运装置工作过程中，转运装置可以先通过水平行走机构移动机架1至待转运电池100的上方，以使得定位组件2可以获取得到转运电池的位置信息，转动调整组件3和水平行走机构根据位置信息调节夹具组件4和待转运电池100的相对位置，使得夹具组件4和待转运电池100沿竖直方向对应，升降机构驱动机架1沿竖直方向落下，直至夹具组件4与待转运电池100接触，夹具组件4中的卡爪421运动至夹持位置，使得夹具组件4和待转运电池100连接，升降机构驱动机架1沿竖直方向提升，使得待转运电池100和安装底座400分离，并通过水平行走机构移动待转运电池100至预设位置，夹具组件4中的卡爪421运动至闭合位置，升降机构驱动机架1沿竖直方向提升，夹具组件4与待转运电池100分离，完成待转运电池100的转运。通过水平行走机构和升降机构可以对夹具组件4和待转运电池100的相对位置进行调节。
请参阅图11至图14，转运装置还包括至少一个到位感应组件5，到位感应组件5包括位置传感器51和活动件52，位置传感器51设置于基座41上并夹具组件4信号连接，活动件52沿竖直方向贯穿基座41设置，活动件52能够沿竖直方向移动以进入或远离位置传感器51的感应区域，位置传感器51被配置为检测活动件52是否进入感应区域并将检测信号发送给夹具组件4；夹具组件4被配置为根据检测信号抓取或释放待转运电池100。
活动件52运动至位置传感器51的感应区域时，位置传感器51检测到活动件52，并向夹具组件4发送检测信号，夹具组件4接收到该检测信号后切换至夹持位置，以抓取或释放待转运电池100。位置传感器51还可以与升降机构信号连接，使得活动件52运动至位置传感器51的感应区域时，位置传感器51可以向升降机构发送检测信号，升降机构接收到该检测信号后停止落下机架1。例如：夹具组件4与待转运电池100在竖直方向对应时，活动件52与待转运电池100的顶端在竖直方向对应，升降机构驱动机架1沿竖直方向落下，直至活动件52与待转运电池100的顶端触碰，升降机构驱动机架1继续沿竖直方向落下，活动件52被待转运电池100的顶端阻挡，使得活动件52与待转运电池100保持相对静止，活动件52与位置传感器51发生相对位 移，活动件52沿竖直方向移动至位置传感器51的感应区域时，位置传感器51感受到活动件52，表明夹具组件4已移动至待转运电池100内，此时可以控制夹具组件4夹取待转运电池100。通过设置位置传感器51和活动件52，可以检测夹具组件4与待转运电池100在竖直方向的位置关系，从而提高夹具组件4夹取待转运电池100的成功率。
根据本申请的一些实施例，参见图5至图7，本申请提供了一种用于转运电池的转运装置，该转运装置包括机架1、定位组件2、转动调整组件3和夹具组件4，定位组件2用于获取待转运电池100的位置信息；转动调整组件3包括第一驱动件31、相啮合的第一齿轮32和第二齿轮33，第一齿轮32与第一驱动件31连接，第二齿轮33与机架1可转动连接；夹具组件4用于抓取或释放待转运电池100，夹具组件4与第二齿轮33远离机架1的一侧连接，第一驱动件31用于根据位置信息驱动第一齿轮32转动，以使第一齿轮32带动第二齿轮33和夹具组件4转动。通过设置定位组件2获取待转运电池100的位置信息，使得转动调整组件3可以根据位置信息调整夹具组件4和待转运电池100的位置关系，提高转运装置智能化；通过设置第一驱动件31、第一齿轮32和第二齿轮33，从而可以通过第一驱动件31驱动第一齿轮32转动，以使第一齿轮32带动第二齿轮33和夹具组件4转动，夹具组件4和待转运电池100沿竖直方向可以准确对应，提高夹具组件4成功拿取待转运电池100的机率，提高转运效率。
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。
