本公开的目的在于提出一种购物车充电装置和和充电系统、扶梯、购物车，能够方便的对购物车进行充电，有效提高购物车的使用效率。
本公开的至少一实施例提供了一种购物车充电装置，该购物车充电装置应用于包括购物车应用场景中。具体的，购物车的车轮包括轮轴和同轴设置在轮轴两端的轮面。扶梯表面上沿其长度方向设置有多个凸起结构。当购物车被推上扶梯时，由于自身重力，轮面和轮轴共同构成的区域能够使扶梯表面的凸起结构嵌入其内，并通过摩擦力使购物车固定在扶梯表面。
本公开的至少一实施例中，所述购物车充电装置应用于购物车，其包括：设置于购物车的车轮的充电电极。
相应的，本公开的至少一实施例还提供了一种购物车充电装置，该购物车充电装置应用于扶梯，其包括：设置于扶梯的电源电极。
在使用时，购物车被推上扶梯后，基于购物车的车轮与扶梯的相接触关系，购物车的车轮上的充电电极能够与扶梯上的电源电极相接触以导通充电回路对购物车进行充电。
本公开的至少一实施例，参考图1和图2，所述的购物车充电装置应用于购物车。所述能购物车充电装置包括：设置在购物车的车轮上的至少一个充电模块。对于一个充电模块，其包括：多个电极单元1，以及与多个电极单元1一一对应的多个测距传感器2。多个电极单元1设置在购物车的一个车轮的轮面100上，且沿轮面100的周向均匀分布。多个测距传感器2设置在车轮的轮轴200表面，且沿轮轴200的周向均匀分布。基于多个电极单元1与多个测距传感器2的一一对应设置关系和沿周向均匀分布的形式，相互对应的一组电极单元1和测距传感器2均处于轮面100的一条径向方向上。
例如，对于一个电极单元1，参考图3和图4，其包括：电磁铁101、弹簧102、永磁铁103、充电电极104。其中，电磁铁101设置于轮面100，且电磁铁101通过弹簧102与永磁铁103相连；充电电极104设置在永磁铁103远离电磁铁101的一面；充电电极104与购物车的电池相连，用于与扶梯表面的凸起结构上设置的电源电极相配合对购物车进行充电。本公开的至少一实施例中，电极单元1具有收起和释放两种状态。在非充电状态下，电极单元1处于收起状态，如图4所示，此时，电磁铁101通电，且磁极性与永磁铁103的磁极性相反，其间产生吸引力，固定在轮面100的电磁铁101将永磁铁103吸附 至轮面100表面并压缩弹簧102。在进行充电时，电极单元1处于释放状态，如图3所示，电磁铁101断电，失去磁极性的电磁铁101与永磁铁103间是去作用力，在一般状态下被压缩的弹簧102的回弹力使永磁铁103向远离电磁铁101的方向弹出，并使永磁铁103上的充电电极104与扶梯表面的凸起结构上的电源电极相接触以导通充电回路对购物车进行充电。
参考图5，本公开的至少一实施例还提供了一种购物车充电装置，该购物车充电装置应用于扶梯。该购物车充电装置，包括：设置在扶梯表面的凸起结构300的侧壁、且沿扶梯长度方向延伸的电源电极3，用于与购物车的车轮上设置的充电模块中的充电电极相配合对购物车进行充电。
在使用时，使用者仅需要将购物车推送到扶梯上，即能够开始为购物车进行充电。具体的，参考图6和图7，购物车被推上扶梯后，由于自身重力，轮面和轮轴共同构成的区域能够使扶梯表面的凸起结构嵌入其内(即使得轮面的一部分将处于扶梯表面以下)，并通过摩擦力使购物车固定在扶梯表面。
为令使用者能够在将购物车推上扶梯后的任意位置均能够实现充电，本公开的至少一实施例中，设置了多个电极单元，该多个电极单元沿车轮的轮面100的周向均匀分布，这样能够保证在轮面100位于扶梯表面以下的区域内至少包括有一个电极单元，且电极单元中的充电电极104面向扶梯表面的凸起结构300。
进一步的，通过个测距传感器2来确定由哪一个电极单元完成充电。对于轮面100处于扶梯表面以下的区域内的电极单元1，为保证电极单元能够顺利从收起状态切换为释放状态并不与扶梯的结构将发生机械干涉，需要选择距离扶梯表面最远的一个电极单元1，而对于距离扶梯表面最远的电极单元1，显然其对应的测距传感器2与扶梯表面的距离最近，即其测距读数最小。故当购物车推上扶梯并固定后，通过购物车的车载控制器检测多个测距传感器2的测距读数并选择其中测距读数最小的一个测距传感器2。然后，将该测距读数最小测距传感器2对应的电极单元1用于为购物车充电。电极单元1起初处于收起状态，参考图3和图4所示，将该电极单元1中的电磁铁101断电，弹簧102将永磁铁103弹出并使充电电极104与其正对的扶梯表面的凸起结构300上的电源电极3相接触以导通充电回路对购物车进行充电。
例如，设置于购物车的购物车充电装置中，充电模块的具体设置形式为：充电模块的数量为二个，包括：设置在购物车一侧的一个车轮上的第一充电模 块和设置在购物车另一侧的另一车轮上的第二充电模块。
本公开的至少一实施例中，在购物车两侧的车轮上，各设置一个充电模块，其分别用作正极和负极。其中，第一充电模块和第二充电模块的结构构成均与前述实施例中的充电模块相同，第一和第二的前缀仅是为了区分其分别设置在购物车不同侧的车轮上。具体的，第一充电模块包括第一充电电极；第二充电模块包括第二充电电极。此处，第一充电电极和第二充电电极均与前述实施例中的充电电极相同，第一和第二的前缀仅是为了区分其电极性，且其电极性相反设置。
本公开的至少一实施例中，以第一充电电极连接购物车电池的负极，第二充电电极连接购物车电池的正极为例。即以使用者的视角划分，本公开的至少一实施例中，购物车左侧的一个车轮上设置有第一充电模块，用作充电的负极；购物车右侧的一个车轮上设置有第二充电模块，用作充电的正极。
例如，在本公开的至少一个实施例的购物车充电装置中，参考图8，将主体4上的扶梯表面以所述扶梯长度方向的中线分为第一区域和第二区域，第一区域和第二区域被通过沿扶梯长度方向的中线的绝缘带分隔开。本公开的至少一实施例中，电源电极包括：设置在所述第一区域内的凸起结构上的第一电源电极和设置在所述第二区域内的凸起结构上的第二电源电极；所述第一电源电极和所述第二电源电极的电极性相反。其中，第一电源电极和第二电源电极均与前述实施例中的电源电极相同，第一和第二的前缀仅是为了区分其所处的区域和电极性，且其电极性相反设置。对应上例，第一区域内的凸起结构上的第一充电电极连接电源的负极，第二区域内的凸起结构上的第二电源电极连接电源的正极。
在使用时，购物车推上扶梯并固定后，购物车左侧的带有第一充电模块的车轮或落入到第一区域内，购物车右侧的带有第二充电模块的车轮或落入到第二区域内，相应的经过与前述实施例的相同的电极单元由收起状态到释放状态的过程后，第一充电电极与第一充电电极相接触，第二充电电极与第二充电电极相接触，实现对购物车的充电。
例如，在本公开实施例的设置于购物车的购物车充电装置中，充电模块的具体设置形式为：充电模块的数量为一个。参考图9，充电电极包括：沿轮面的径向依次设置的第一电极片1041和第二电极片1042；第一电极片1041和第二电极片1042的电极性相反。在本公开的至少一实施例中，分别用作正负电 极的第一电极片1041和第二电极片1042设置一个电极单元中的永磁铁上，这样整个购物车上，仅在一个车轮上设置一个充电模块即可。
例如，在本公开的至少一个实施例的购物车充电装置中，参考图10，电源电极包括：沿垂直于所述扶梯表面方向依次设置的第一电极带301和第二电极带302；第一电极带301和第二电极带302的电极性相反。
在使用时，购物车推上扶梯并固定后，经过与前述实施例的相同的电极单元由收起状态到释放状态的过程后，第一电极片1041与第一电极带301相接触，第二电极片1042与第二电极带302相接触，实现对购物车的充电。
例如，设置于购物车的购物车充电装置还包括：设置在购物车的车身的指示灯，用于指示购物车充电状态。其中，对应于对于正常充电和无法正常充电两种充电状态，指示灯以两种不同的方式工作。具体的，当充电电极与电源电极接触良好，能够正常进行充电时，指示灯熄灭；当充电电极与电源电极接触不良或出现故障，不能正常进行充电时，指示灯点亮。点亮的指示灯能够提示使用者实时了解当前购物车的充电状态。显然，指示灯的不同方式工作还可以设置为亮度不同、颜色不同、闪烁频率不同等。
例如，参考图5，本公开的至少一个实施例的购物车充电装置还包括：沿凸起结构300的顶部延伸设置的绝缘层3001，该绝缘层3001的边缘能够覆盖相邻凸起结构300的间隙。通过绝缘层3001的设置，能够充电电极和电源电极与购物车和扶梯的其他部位隔开，提升绝缘性。另一方面，绝缘层3001还能够有效的增加与购物车的车轮的轮面间的摩擦，进一步的提高购物车固定在扶梯表面的稳固程度。
本公开实施例提供一种扶梯，包括上述购物车充电装置和主体4，其中所述充电装置设置于所述主体4上允许与购物车的车轮上设置的充电电极相配合对所述购物车进行充电的位置。
本公开实施例提供一种购物车充电系统，包括上述购物车和扶梯。对于本公开的至少一实施例的购物车充电装置和充电系统、扶梯、购物车，其还可以与通过购物车上的车载控制器、通信模块，与卖场内的服务器之间的交互，实现更多的功能，包括：
(1)将购物车的当前电池电量通过通信模块向服务器反馈。进一步的，根据购物车的当前电池电量判断是否需要进行充电。
(2)通过室内定位系统，判断购物车在卖场内所处的位置。进一步的， 通过购物车上设置的电子标签与扶梯上设置的读取装置，判断购物车进入、离开扶梯的事件，以及在购物车离开扶梯的时，将电极单元从释放状态切换回收起状态。或者是，根据扶梯上当前正在充电的购物车的数量，判断新进入扶梯的购物车是否可以进行充电。
综上所述，本公开提供的购物车充电装置和充电系统、扶梯、购物车，通过在购物车的车轮上的充电模块包括的电极单元中的充电电极与扶梯表面的凸起结构上设置的电源电极相配合，实现在购物车被推上扶梯时即能够对购物车进行充电，装置结构简单，使用上方便快速，有效的提高了购物车的使用效率。
以上所述仅是本公开的示范性实施方式，而非用于限制本公开的保护范围，本公开的保护范围由所附的权利要求确定。
