Description

支架、电池组件及用电设备 技术领域
本申请涉及电池领域，具体而言，涉及一种支架、电池组件及用电设备。
背景技术
电池作为车辆的主要储能元件，是车辆的关键部件，直接影响着车辆的性能。在相关技术中，电池或是直接安装到车辆的车身，或是采用支架安装到车身。在直接安装到车身的方式中，通常利用螺栓连接电池和车身，但是，电池的安装和拆卸不方便，不利于电池的快速更换。在采用支架将电池安装到车身的方式中，支架通常为长方体的环形框，用于安装单个电池。在支架的长度方向上，其中部的强度低，导致电池在支架上的安装可靠性得不到保证。
发明内容
本申请实施例旨在提供一种支架、电池组件及用电设备，能够保证电池在支架上安装的可靠性。
第一方面，提供了一种支架，用于与电池和用电设备本体连接，所述电池包括密封的箱体和容纳于所述箱体内的电池单体，所述支架包括一对第一梁和至少一个支撑梁，所述一对第一梁相对设置，每个支撑梁均与所述一对第一梁连接，所述至少一个支撑梁将所述一对第一梁之间的空间分隔为多个子空间，所述多个子空间沿所述第一梁的长度方向排列，每个子空间用于容纳至少一个所述电池，每个支撑梁分隔相邻的两个子空间，并且用于安装容纳于所述相邻的两个子空间的所述电池的所述箱体。
相较于相关技术支架，本申请实施例提供的支架由于设置了支撑梁，增大了支架自身的强度。因此，在安装电池时，能够提升电池安装的可靠性。
而且，由于相邻子空间内的电池采用支撑梁作为公共的安装结构，可以使得支架结构更为紧凑，空间利用率高。因此，在车辆的电池安装空间一定的情况下，能够尽可能增大电池容纳空间的尺寸，从而利于增大电池的体积，增大电池的能量密度。
在一些实施例中，所述支架包括第一锁止机构，所述第一锁止机构安装于所述支撑梁，用于将所述电池的所述箱体锁定在所述支撑梁上。
在一些实施例中，所述第一锁止机构设置在所述支撑梁的内部。
将第一锁止机构设置在支撑梁的内部的好处在于：其一，能够节约空间，增大支架的电池容纳空间；其二，能够起到对第一锁止机构的保护作用，使得第一锁止机构免受外界环境的影响，例如，免受雨水、泥浆的侵蚀，保证了第一锁止机构锁止和解锁的可靠性；其三，由于支撑梁设置为中空结构，能够减重，利于支架的轻量化。
在一些实施例中，所述支撑梁包括支撑梁本体和支撑梁盖体，所述支撑梁本体的横截面呈U型且具有开口，所述第一锁止机构设置在所述支撑梁本体的内部，所述支撑梁盖体盖合于所述支撑梁本体的所述开口。
支撑梁本体为U型设计，在保证给第一锁止机构提供安装空间的同时，结构还较为简单。

在一些实施例中，所述支撑梁上设置有沿重力方向延伸的通道，所述通道延伸至所述支撑梁的下表面以使设置于所述箱体的锁止部能够进出所述通道；所述第一锁止机构配置为在所述锁止部向上移动至所述通道的预定位置时，可将所述锁止部锁止；且所述第一锁止机构被配置为可解除对所述锁止部的锁止，以使所述锁止部在所述电池的重力作用下向下移动以脱离所述通道。
在电池的锁止或解锁过程中，电池仅需在通道内向上或向下移动，无须在其他方向(如车辆的前后方向)对电池进行调整。尤其在对电池进行解锁时，当第一锁止机构解除对锁止部的锁止后，电池的锁止部能够在电池的重力作用下脱离通道，使得电池的锁止和解锁都较为方便、快捷，有利于提升电池包安装和拆卸的效率，利于实现电池的快速更换。另外，对于支撑梁，仅需在其上设置通道以与锁止部配合即可，无需做过多的设计，利于简化支撑梁的结构。

在一些实施例中，所述第二梁包括的第二梁本体和第二梁盖体，所述第二梁本体的横截面呈U型且具有开口，所述第二锁止机构设置在所述第二梁本体的内部，所述第二梁盖体盖合于所述第二梁本体的所述开口。
第二梁本体为U型设计，在保证给第一锁止机构提供安装空间的同时，结构还较为简单。
在一些实施例中，所述第二梁本体的所述开口向下。
当支架安装到车身上后，由于第二梁本体的开口向下，当第二锁止机构或其他设置于第二梁本体内的机构出现问题时，方便对第二锁止机构或其他机构进行维修或更换。
在一些实施例中，所述第二梁上设置有沿重力方向延伸的通道，所述通道延伸至所述第二梁的下表面以使设置于所述箱体的锁止部能够进出所述通道；所述第二锁止机构被配置为在所述锁止部向上移动至所述通道的预定位置时，可将所述锁止部锁止；且所述第二锁止机构被配置为可解除对所述锁止部的锁止，以使所述锁止部在所述电池的重力作用下向下移动以脱离所述通道。

另外，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/或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包等。电池单体包括正极极片、负极极片、电解液和隔离膜，隔离膜设置在正极极片和负极极片之间以防止内短路。常见的电池单体按封装的方式一般可分成三种：柱形电池单体、方形电池单体和软包电池单体。
多个电池单体可经由汇流条而被串联和/或并联在一起以应用于各种应用场合。在一些诸如电动汽车等的大功率应用场合，电池的应用一般包括三个层次：电池单体、电池模块和电池包。电池模块是为了将一定数目的电池单体电连接在一起。电池包是在一个或多个电池模块的基础上装配电池管理系统等部件，然后装入密封的箱体中，箱体再与电动汽车的底盘连接。
如图1所示，本申请实施例提供一种使用电池作为电源的用电设备1。用电设备1包括用电设备本体20和电池组件10，电池组件10包括支架100和电池200。支架100安装于用电设备本体20，电池200安装于支架100。即，电池200与用电设备本体20通过支架100连接。支架100能够为电池200安装提供安装空间，方便电池200的快速更换。
可以理解的是，本申请实施例描述的电池适用于各种使用电池的装置，例如，手机、便携式设备、笔记本电脑、电瓶车、电动汽车、轮船、航天器、电动玩具和电动工具等等，例如，航天器包括飞机、火箭、航天飞机和宇宙飞船等等，电动玩具包括固定式或移动式的电动玩具，例如，游戏机、电动汽车玩具、电动轮船玩具和电动飞机玩具等等，电动工具包括金属切削电动工具、研磨电动工具、装配电动工具和铁道用电动工具，例如，电钻、电动砂轮机、电动扳手、电动螺丝刀、电锤、冲击电钻、混凝土振动器和电刨。
本申请的实施例描述的电池200不仅仅局限适用于上述所描述的用电设备，还可以适用于所有使用电池的设备。
在本申请一个实施例中，用电设备1为车辆，用电设备本体20为车辆的车身。如图1所示，为本申请一个实施例的一种车辆的结构示意图，车辆可以为燃油汽车、燃气汽车或新能源汽车，新能源汽车可以是纯电动汽车、混合动力汽车或增程式汽车等。车辆的内部可以设置马达，控制器以及电池，控制器用来控制电池为马达供电。电池可以设置在车辆的底部或车头或车尾。电池可以用于车辆的供电，例如，电池可以作为车辆的操作电源，用于车辆的电路系统，例如，用于车辆的启动、导航和运行时的工作用电需求。在本申请的另一实施例中，电池不仅仅可以作为车辆的操作电源，还可以作为车辆的驱动电源，替代或部分地替代燃油或天然气为车辆提供驱动动力。
如图1所示，本申请实施例提供的支架100上形成有多个用于安装电池200的子空间115，每个子空间115容纳有至少一个电池200。由于该电池组件10的支架100能够携带至少两个独立的电池200， 使得当其中一个或几个电池200被拆卸以进行充电或者维修时，仍然能够利用剩余的电池200继续向车辆供电，保证了车辆的正常运行。而且，当其中一个电池200损坏时，其余电池200可以继续使用，利于降低电池200成本。
本申请的支架100可以具有任意适当的结构。如图2至图8所示，在本申请的实施例中，支架100可包括一对第一梁111和至少一个支撑梁117。其中，一对第一梁111相对设置，每个支撑梁117均与一对第一梁111连接，至少一个支撑梁117将一对第一梁111之间的空间分隔为多个子空间115。即，子空间115的数量为两个及两个以上。多个子空间115沿第一梁111的长度方向排列，每个子空间115用于容纳至少一个电池200，每个支撑梁117分隔相邻两个子空间115，并且用于安装容纳于相邻的两个子空间115的电池200的箱体210。
在本申请实施例提供的支架100中，通过设置支撑梁117，增大了支架100自身的强度。因此，在安装电池200时，能够提升电池200的安装可靠性。
而且，由于相邻子空间115内的电池200采用支撑梁117作为公共的安装结构，可以使得支架100结构更为紧凑，空间利用率高。因此，在车辆的电池安装空间一定的情况下，有利于增大电池200的体积，增大电池200的能量密度。
此外，如上文提及的，支架100能够携带至少两个独立的电池200，使得当其中一个或几个电池200被拆卸以进行充电或者维修时，仍然能够利用剩余的电池200继续向车辆供电，保证了车辆的正常运行。而且，当其中一个电池200损坏时，其余电池200可以继续使用，利于降低电池200成本。
在本申请实施例提供的支架100中，支架100可以具有任意适当的形状，子空间115的数量可以具有为任意的多个，如两个、三个、四个等。具体可以根据电池200的尺寸以及车辆等用电设备1的电池安装空间等因素决定。
如图2所示，在本申请的一种实施例中，支架100包括一对第一梁111和一个支撑梁117，该一对第一梁111与一个支撑梁117连接呈“工”字型。该支架100具有两个子空间115。在支架100安装到车身上后，该两个子空间115可沿车辆的纵向排列。当然，该两个子空间115也可沿车辆的横向排列。
在本实施例中，两个子空间115在第一梁111的长度方向的尺寸L1相等。这样，两个子空间115可用于安装在第一梁111的长度方向的尺寸L1相同的电池200，可实现电池200在第一梁111的长度方向的尺寸L1的标准化。
在本实施例中，两个子空间115的沿一对第一梁111的排列方向的尺寸L2相等。这样，两个子空间115可用于安装在一对第一梁111的排列方向的尺寸L2相同的电池200，可实现电池200沿一对第一梁111排列方向的尺寸L2的标准化。
在本实施例中，两个子空间115的在第一梁111的长度方向的尺寸L1相等，并且两个子空间115的沿一对第一梁111的排列方向的尺寸L2也相等。这样，两个子空间115可以用于安装各尺寸相同的电池200，可实现电池200的各尺寸标准化。
电池200实现标准化后，使得不同车型可共用一种尺寸规格的电池200，换电站无需准备多种尺寸规格的电池200，仅需准备一种尺寸规格的电池200即可，极大降低换电站的投入成本及对于电池200的管理成本。
如图3所示，在本申请的一种实施例中，支架100包括一对第一梁111和一对支撑梁117，一对支撑梁117在第一梁111的长度方向上间隔布置。该支架100具有沿第一梁111的长度方向排列的三个子空间115。在支架100安装到车身上后，该三个子空间115可沿车辆的纵向排列。当然，该三个子空间115也可沿车辆的横向排列。
在本实施例中，三个子空间115的在第一梁111的长度方向的尺寸L1相等。这样，三个子空间115可用于安装在第一梁111的长度方向的尺寸L1相同的电池200，可实现电池200在第一梁111的长度方向的尺寸L1的标准化。
在本实施例中，三个子空间115在一对第一梁111的排列方向的尺寸L2相等。这样，三个子空间115可用于安装沿一对第一梁111的排列方向的尺寸L2相同的电池200，可实现电池200沿一对第一梁111的排列方向的尺寸L2的标准化。
在本实施例中，三个子空间115的在第一梁111的长度方向的尺寸L1相等，并且三个子空间115 在一对第一梁111的排列方向的尺寸L2也相等。这样，三个子空间115可以用于安装各尺寸相同的电池200，可实现电池200的各尺寸标准化。
如图4至图8所示，在本申请的一些实施例中，支架100还包括一对第二梁112，一对第二梁112相对设置，每个第二梁112均与一对第一梁111连接，至少一个支撑梁117位于一对第二梁112之间，至少一个支撑梁117被配置为将一对第一梁111和一对第二梁112围成的空间分隔为多个子空间115。
由于每个第二梁112均与一对第一梁111连接，使得支架100可具有环形结构，环形结构能够增加支架100的强度和结构稳定性，进一步保证了支架100安装电池200的可靠性。而且，通过设置第二梁112，利于增加支架100与电池200及用电设备本体20之间的连接，以保证支架200与两者连接的可靠性。例如，下文将介绍的在第二梁112上设置第二锁止机构122及第三连接部1123。
在图4所示的实施例中，支架100包括一对第一梁111、一对第二梁112及一个支撑梁117。一对第一梁111、一对第二梁112及一个支撑梁117相连呈“日”字型。该支架100具有两个子空间115。

在本申请的实施例中，每个子空间115在第一梁111的长度方向的尺寸L1可以为任意适当的值，具体可根据电池200而定。每个子空间115在第一梁111的长度方向的尺寸L1可为400mm至800mm。子空间115在第一梁111的长度方向的尺寸L1设计是根据不同车型车辆的电池安装空间以及续航里程等因素综合考虑，使得电池200既能安装于车辆，也能够使得电池200满足不同车型的车辆对电池电量的要求。
在本申请的实施例中，每个子空间在一对第一梁111的排列方向的尺寸L2可为1000mm至1400mm。每个子空间在一对第一梁111的排列方向的尺寸L2设计，是根据不同车型车辆的电池安装空间以及续航里程等因素综合考虑，使得电池200既能安装于车辆，也能够使得电池200满足不同车型的车辆对电池电量的要求。
在图6所示的实施例中，支架100包括一对第一梁111、一对第二梁112及一个支撑梁117。其中，第一梁111包括相连的第一段111a和第二段111b，第一段111a和第二段111b成钝角连接，支撑梁117连接于第一段111a和第二段111b的结合部。该支架100具有两个子空间115。
在图7所示的实施例中，支架100包括一对第一梁111、一对第二梁112及一个支撑梁117。其中，第一梁111包括相连的第一段111a、第二段111b和第三段111c，第一段111a和第二段111b成直角连接，第二段111b和第三段111c成直角连接。支撑梁117连接于第二段111b和第三段111c的结合部。该支架100具有两个子空间115。

在图8所示的实施例中，两个子空间115的在第一梁111的长度方向的尺寸L1相等，并且两个子空间115在一对第一梁111的排列方向的尺寸L2也相等。这样，两个子空间115可以用于安装各尺寸相同的电池200，可实现电池200的各尺寸标准化。
为了将支架100固定用电设备1，在本申请的一种实施例中，第一梁111上设置有用于与用电设备本体20(如车辆的车身)连接的第一连接部1113，和/或，支撑梁117上设置有用于与用电设备本体20连接的第二连接部1173，和/或，第二梁112上设置有用于与用电设备本体20连接的第三连接部1123。
可以理解的是，在本申请中，支架100既可以仅设置第一连接部1113、第二连接部1173及第三连接部1123中的一者，也可以设置第一连接部1113、第二连接部1173及第三连接部1123中任意两者或者同时设置三者。如图9所示，支架100可同时设置第一连接部1113、第二连接部1173和第三连接部1123，以保证支架100与车身连接的可靠性。
第一连接部1113、第二连接部1173及第三连接部1123可以具有任意适当的结构。如图9所示，在本申请的一种实施例中，第一连接部1113和第三连接部1123可均为凸耳，凸耳从对应的梁的外侧壁(远离电池200的壁)向外延伸。第一连接部1113上设置有第一安装孔1114，第三连接部1123上设置有第三安装孔1124。紧固件分别穿过第一安装孔1114和第三安装孔1124以将支架100连接到用电设备本体20上。
如图9所示，在本申请的一种实施例中，第二连接部1173可为螺母结构，具有第二安装孔1174，螺纹紧固件穿过该第二安装孔1174以将支撑梁117连接到用电设备本体20，以实现支架100与用电设备本体20的螺接固定。
在本申请的其他实施例中，第二连接部1173可为卡舌，用电设备本体20上设有与该卡舌配合的卡扣，第二连接部1173与用电设备本体20采用卡接固定。
如图10所示，电池组件10包括支架100和安装于支架100上的两个电池200。支架100上还设置有用于安装电气元件的承载部118，该电气元件可以是用于将多个电池200的电能输送到用电设备本体20的连接器。
需要说明的是，在本申请的实施例中，支架100不仅可以为平面支架，还可为立体支架。即，多个子空间115不仅可以位于同一水平面，还可位于不同的水平面。这样，当车辆存在位于不同水平面的安装面时，支架100可以更好的适应车辆的结构，使得支架100与车辆的车身之间安装更为紧凑。
另外，在本申请的实施例中，支架100可以采用任意适当的成型方式。例如，支架100可采用一体成型(如铸造)的方式或采用焊接的方式。
如图11所示，电池200包括密封的箱体210和容纳于箱体210内的电池单体220，箱体210上设置有锁止部211。其中，箱体210可包括下壳体212和上盖213，电池单体220容置在下壳体212和上盖213限定的密封腔体内。
如图12至图14所示，在本申请的一种实施例中，支架100上设置有第一锁止机构121，该第一锁止机构121安装于支撑梁117。第一锁止机构121用于将电池200的箱体210锁定在支撑梁117上，以实现支架100对电池200的固定，如图14所示。
具体地，第一锁止机构121通过对箱体210上的锁止部211进行锁止，从而实现对电池200的锁止。若需要更换电池200，可解除第一锁止机构121对电池200的锁止部211的锁定，将电池200取下。当新的电池200放置到容纳空间时，利用第一锁止机构121将新的电池200的锁止部211锁止即可。
第一锁止机构121可设置在支撑梁117上任意适当的位置。如图13所示，在本申请的一种实施例中，第一锁止机构121可设置在支撑梁117的内部。将第一锁止机构121设置在支撑梁117的内部的好处在于：其一，能够节约空间，增大支架100的电池容纳空间；其二，能够起到对第一锁止机构121的保护作用，使得第一锁止机构121免受外界环境的影响，例如，免受雨水、泥浆的侵蚀，保证了第一锁止机构121锁止和解锁的可靠性；其三，由于支撑梁117设置为中空结构，能够减重，利于支架100的轻量化。
本申请对第一锁止机构121的数量及在支撑梁117上的排布不作限定。如图13所示，在本申请的一种实施例中，每个支撑梁117可安装有两排第一锁止机构121，两排第一锁止机构121沿第一梁111的长度方向排列，且每排第一锁止机构121包括多个沿一对第一梁111的排列方向排列的第一锁止机构121。即，两排第一锁止机构121沿子空间115的排布方向设置，两排第一锁止机构121分别用于锁定容纳于相邻两个子空间115的电池200的箱体210。通过设置两排第一锁止机构121将电池200锁止在支撑梁117上，有利于提升支撑梁117对电池200的安装强度。而且两排第一锁止机构121沿两个子空间115的排列方向排列，还使得支撑梁117的对应两侧受力均匀，不易对支撑梁117造成损坏。
如图13所示，在支撑梁117的内部，两排第一锁止机构121可在支撑梁117的长度方向上错位安装，以在支撑梁117满足安装强度的前提下，减小支撑梁117的宽度，以尽可能增大支架100用于安装电池的空间。
如图13所示，支架100还包括第二锁止机构122，第二锁止机构122安装于第二梁112，用于将电池200的箱体210锁定在第二梁112上。同样，第二锁止机构122通过对设置于箱体210的锁止部211进行锁止，以实现对箱体210的锁止。
在本申请的实施例中，支架100既可以仅通过第一锁止机构121和第二锁止机构122中的一者对电池200进行锁止。也可以如图13和图14所示的实施例，支架100同时通过第一锁止机构121和第二锁止机构122对电池200进行锁止，以充分保证支架100对电池200锁止的可靠性。
如图13所示，第二锁止机构122设置在支第二梁112的内部。将第二锁止机构122设置在第二梁112的内部的好处在于：其一，能够节约空间，增大支架100的电池容纳空间；其二，能够起到对第二锁止机构122的保护作用，使得第二锁止机构122免受外界环境的影响，例如，免受雨水、泥浆的侵蚀，保证了第二锁止机构122锁止和解锁的可靠性；其三，由于第二梁112设置为中空结构，能够减重，利于支架100的轻量化。
本申请对支撑梁117的具体结构不作限定。如图12和图13所示，在本申请的一种实施例中，支撑梁117可以包括支撑梁本体1171和支撑梁盖体1172，支撑梁本体1171的横截面呈U型且具有开口，第一锁止机构121设置在支撑梁本体1171的内部，支撑梁盖体1172盖合于支撑梁本体1171的开口。支撑梁本体1171为U型设计，在保证给第一锁止机构121提供安装空间的同时，结构还较为简单。支撑梁本体1171的开口向下。
需要说明的是，这里的“向下”指支架100安装到用电设备本体20上时，开口朝向重力方向。这样，当支架100安装到车身上后，由于支撑梁本体1171的开口向下，当第一锁止机构121或其他设置于支撑梁本体1171内的机构出现问题时，方便对第一锁止机构121或其他机构进行维修或更换。
同样，本申请对第二梁112的具体结构也不作限定。如图12和图13所示，在本申请的一种实施例中，第二梁112可包括的第二梁本体1121和第二梁盖体1122，第二梁本体1121的横截面呈U型且具有开口，第二锁止机构122设置在第二梁本体1121的内部，第二梁盖体1122盖合于第二梁本体1121的开口。第二梁本体1121为U型设计，在保证给第二锁止机构122提供安装空间的同时，结构还较为简单。
第二梁本体1121的开口向下。需要说明的是，这里的“开口向下”指支架100安装到用电设备本体20上时，开口朝向重力方向。这样，当支架100安装到车身上后，由于第二梁本体1121的开口向下，当第二锁止机构122或其他设置于第二梁本体1121内的机构出现问题时，方便对第二锁止机构122或其他机构进行维修或更换。
如图12和图13所示，第一梁111也可包括第一梁本体1111和第一梁盖体1112，第一梁本体1111的横截面呈U型且具有开口，第一梁盖体1112盖合于第一梁本体1111的开口。第一梁本体1111的开口向下。第一梁111如此分体设置的优点与支撑梁117和第二梁112分体设计具有的优点类似，这里不再赘述。
在本申请中，锁止机构除了包括上述的第一锁止机构121和第二锁止机构122，还可包括第三锁止机构，本申请对此不作限定。例如，当设有第三锁止机构时，可将第三锁止机构设置在第一梁111上。
在本申请的实施例中，第一锁止机构121和第二锁止机构122既可以采用相同的结构，也可以采用不同的结构。为了简化支架100的结构，降低成本，在本申请的一种实施例中，第一锁止机构121和第二锁止机构122采用相同的结构。
本申请的一个目的是能够实现电池200的快速更换。相关技术的支架的锁止机构结构复杂，锁止及解锁的过程复杂，不利于电池200的快速更换。
鉴于此，如图15至18所示，支撑梁117设置有沿重力方向延伸的通道116。通道116延伸至支撑梁117的下表面以使设置于箱体210的锁止部211能够进出通道116。其中，第一锁止机构121被配置为在锁止部211向上移动至通道116的预设位置，可将锁止部211锁止；且第一锁止机构121被配置为可解除对锁止部211的锁止，以使锁止部211在电池200的重力作用下向下移动以脱离通道116。
基于上述方案，在电池200的锁止或解锁过程中，电池200仅需在通道116内向上或向下移动，无须在其他方向(如车辆的前后方向)对电池200进行调整。尤其在对电池200进行解锁时，当第一锁止机构121解除对锁止部211的锁止后，电池200的锁止部211能够在电池200的重力作用下脱离通道116，使得电池200的锁止和解锁都较为方便、快捷，有利于提升电池200安装和拆卸的效率，利于实现电池200包的快速更换。另外，对于支撑梁117，仅需在其上设置通道116以与锁止部211配合即可，无需做过多的设计，利于简化支撑梁117的结构。
如图16至图18所示，第二梁112设置有沿重力方向延伸的通道116。通道116延伸至第二梁112的下表面以使设置于箱体210的锁止部211能够进出通道116。其中，第二锁止机构122被配置为在锁止部211向上移动至通道116的预设位置，可将锁止部211锁止；且第二锁止机构122被配置为可解除对锁止部211的锁止，以使锁止部211在电池200的重力作用下向下移动以脱离通道116。
基于上述方案，在电池200的锁止或解锁过程中，电池200仅需在通道116内向上或向下移动，无须在其他方向(如车辆的前后方向)对电池200进行调整。尤其在对电池200进行解锁时，当第二锁止机构122解除对锁止部211的锁止后，电池200的锁止部211能够在电池200的重力作用下脱离通道116，使得电池200的锁止和解锁都较为方便、快捷，有利于提升电池200安装和拆卸的效率，利于实现电池200包的快速更换。另外，对于第二梁112，仅需在其上设置通道116以与锁止部211配合即可，无需做过多的设计，利于简化第二梁112的结构。
其中，通道116的“预定位置”可以是通道116延伸方向的内任意适当的位置，本申请对此不作限定。
在本申请的实施例中，支撑梁117上设置有多个通道116和多个第一锁止机构121，多个第一锁止机构121与多个通道116一一对应。
在本申请的实施例中，第二梁112上设置有多个通道116和多个第二锁止机构122，多个第二锁止机构122与多个通道116一一对应。
为了节约对电池200进行锁止和解锁的时间，提升电池200更换效率。可选地，在本申请的一种实施例中，多个第一锁止机构121被配置为可同步锁止或同步解锁。多个第二锁止机构122被配置为可同步锁止或同步解锁。
在本申请的实施例中，第一锁止机构121和第二锁止机构122可以为任意适当的结构。以第一锁止机构121为例，如图19至图21所示，在本申请实施例中，第一锁止机构121可包括第一锁止件123和第二锁止件124。第一锁止件123可转动地安装于支撑梁117。
第二锁止件124被配置为当第一锁止件123转动至锁止位置时可阻止第一锁止件123转动，以使第一锁止件123保持在锁止位置。第一锁止件123被配置为当其处于锁止位置时，可阻止位于通道116预定位置的锁止部211向下移动。
如此，当电池200的锁止部211移动至通道116的预定位置后，通过第一锁止件123与第二锁止件124的配合，可将锁止部211锁止在通道116内，实现对电池200的锁止。需要解锁时，可先解除第二锁止件124对第一锁止件123的限位，使第一锁止件123从锁止位置转动到解锁位置，以实现对电池200的解锁。
第一锁止件123和第二锁止件124可以为任意适当的结构，只要能够顺利实现对电池200的锁止部211的锁止和解锁即可。
如图19和图20所示，在本申请的一种实施例中，第一锁止件123可为棘轮，第二锁止件124可为棘爪。棘轮被配置为在锁止部211向上移动的过程中，可被锁止部211带动以沿第一方向A1转动。棘爪被配置为在锁止部211向上移动至通道116的预定位置时，与棘轮啮合以阻止棘轮转动，例如，阻止棘轮沿与第一方向A1相反的第二方向A2转动，从而通过棘轮将锁止部211锁止在通道116内，实现对电池200的锁止。
棘轮可通过第一转轴1261可转动地安装于支撑梁117,棘爪可通过第二转轴1262可转动地安装于支撑梁117。
在本实施例中，棘轮和棘爪的配合，能够保证对锁止部211锁止的可靠性，保证了电池200在支架100上安装的可靠性。而且，当需要解锁电池200时，使棘爪与棘轮分离即可，操作方便、快捷。
棘轮上可具有一个棘轮齿或多个棘轮齿。当棘轮上设置多个棘轮齿时，通过不同位置的棘轮齿与棘爪配合，可使得电池200的锁止部211在支架100的通道116内具有多个锁止位置。
为了方便对电池200的锁止部211进行限位。如图19和图20所示，棘轮上设有用于卡接锁止部211的卡接口1231。
支架100上未安装电池200时，可使棘轮的卡接口1231朝向重力方向。在锁止部211沿通道116向上移动的过程中，锁止部211进入卡接口1231。在锁止部211继续向上移动时，锁止部211抵顶卡 接口1231的侧壁，使得棘轮转动。当卡接口1231转动至一定位置后，例如，当卡接口1231转动至如图15所示的朝向水平方向时，若此时棘爪对棘轮锁止，则卡接口1231能够对锁止部211进行竖直方向的锁止。
为了保证棘爪与棘轮啮合的可靠性，可选地，如图19所示，第一锁止机构121还可包括第一弹性件1251，第一弹性件1251作用于棘爪，以使棘爪与棘轮抵接。这样，一方面，当棘轮转动至锁止位置时，在第一弹性件1251的作用下，棘爪能够及时移动至与棘轮锁止，实现对锁止部211的快速锁止。另一方面，在第一弹性件1251的弹性力的作用下，棘爪能够与棘轮保持啮合，因此，保证了第一锁止机构121对电池200锁止的可靠性。
如图19所示，第一弹性件1251为扭簧，扭簧可套设在第二转轴1262上，扭簧的一端与第二锁止件124相连，另一端可与驱动件(未图示)相连。
如图19所示，在本申请的一种实施例中，支架100上可还设有位置传感器130，以用于检测第一锁止件123(即棘轮)的位置，从而判定电池200锁止/解锁是否到位。
如图19和图20所示，第一锁止机构121可还包括弹性垫129，该弹性垫129设置通道116的上端，以实现对锁止部211向上移动的缓冲。
如图21所示，在本申请的另一种实施例中，第一锁止件123上设有可供锁止部211穿过的避空部1232。第二锁止件124被配置为可带动第一锁止件123转动，以使得避空部1232和通道116在重力方向错位或连通，以实现对锁止部211的锁止或解锁。
如图21所示，在本实施例中，第一锁止件123在初始状态时，其避空部1232和通道116在重力方向错位。若需对电池200进行锁止，首先，可通过第二锁止件124带动第一锁止件123沿第一方向A1转动至其避空部1232与通道116连通的位置，使电池200的锁止部211经避空部1232进入通道116，直至锁止部211位于通道116内的预定位置。然后，通过第二锁止件124带动第一锁止件123第二方向A2转动至其避空部1232与通道116错位的位置。如此，第一锁止件123能够将锁止部211封堵在通道116内，实现对锁止部211的锁止，从而实现对电池200的锁止。若需要对电池200进行解锁，可通过第二锁止件124带动第一锁止件123沿第一方向A1转动至其避空部1232与通道116连通的位置。如此，电池200在自身重力下即可实现与支架100的分离。在本实施例中，电池200的锁止和解锁，同样方便、快捷。
如图21所示，第一锁止件123为齿轮，该齿轮可转动地安装于支撑梁117。通道116至少部分位于齿轮的中心孔内。第二锁止件124为与齿轮啮合的齿条，可移动地安装于支撑梁117。齿条被配置为可带动齿轮转动使得避空部1232和通道116在重力方向连通或错位，以实现对锁止部211的解锁或锁止。
当齿轮的避空部1232(连通齿轮中心孔与外周壁的开口)与通道116错位时，齿轮的中心孔的内壁阻止电池200的锁止部211从通道116的预定位置向下移动，实现对电池200的锁止。当齿轮的避空部1232与通道116连通时，电池200的锁止部211能够从通道116的预定位置向下移动，实现对电池200的解锁。齿轮齿条传动的可靠性高，有利于保证电池200锁止和解锁的可靠性。
为了方便将齿轮可转动地安装在支撑梁117上。如图21所示，在本申请的一种实施例中，支撑梁117上设有凸台1271，齿轮可转动地套设于凸台1271。通道116设于凸台1271的端面，通道116延伸至凸台1271的外周面。如此，当齿轮在绕凸台1271转动过程中，齿轮的避空部1232能够与通道116的连通，以使避让电池200的锁止部211，或者，能够与通道116错开，利用齿轮的中心孔的内壁封堵住滑道的下端，实现对锁止部211的锁止。
如图21所示的实施例中，齿条被配置为可在第一位置和第二位置之间移动，齿轮被配置为在齿条移动至第一位置时将锁止部211锁止，在齿条移动至第二位置时解除对锁止部211的锁止。第一锁止机构121还包括第二弹性件1252，第二弹性件1252与齿条连接，用于驱使齿条从第二位置移动至第一位置。这里，第二弹性件1252用于将齿条保持在第一位置，以将齿轮保持在锁止位置。
如图21所示，第二弹性件1252可为弹簧。在齿条位于第一位置时，弹簧处于自由伸长状态。
为了保证齿条沿预设的线路顺利移动。如图21所示，支撑梁117上设置有两个相对设置的安装块1272，两个安装块1272上对应位置设置有导槽1273，齿条的两端分滑动安装在对应导槽1273内。通 过两个导槽1273对齿条的导向，使得齿条能够按预设线路移动，保持齿轮的顺利转动，从而保证了对电池200解锁和锁止的可靠性。
如图21所示，第一锁止机构121还包括限位件128，限位件128安装于第一锁止机构121，限位件128被配置为在齿轮沿第二方向A2转动至锁止位置时与齿轮抵接，以限制齿轮沿第二方向A2继续转动。通过设置限位件128，保证了对电池200锁止的可靠性。
如图21所示，第一锁止机构121可还包括弹性垫129，该弹性垫129设置在通道116的上端，以实现对锁止部211向上移动的缓冲。
如图21所示，在本申请的一种实施例中，齿轮可包括第一环形部1233和第二环形部1234，其中，第一环形部1233和第二环形部1234沿齿轮的中心孔的轴向布置。第一环形部1233的外周缘设置有用于与齿条啮合的齿，第二环形部1234上开口以构造出上述的避空部1232。在齿轮绕凸台1271转动过程中，第二环形部1234上的开口能够与支撑梁117上的通道116连通或错位，以实现对电池200解锁或锁止。
通过将齿轮分为第一环形部1233和第二环形部1234，使得在齿轮上开设避空部1232的同时还使得齿轮能够具有周向连续的齿。
需要说明的是，在本申请的其他实施例中，可直接在齿轮的第一环形部1233上开口以形成上述的避空部1232。从而省去第二环形部1234。
此外，在本申请的其他实施例中，第一锁止件123和第二锁止件124可均为齿轮，两者均可转动地安装在支撑梁117上且两者啮合转动。其中，第一锁止件123设置有上述的避空部1232。这样，第二锁止件124转动时可带动第一锁止件123转动，实现避空部1232和通道116在重力方向连通或错位，以实现对锁止部211的解锁或锁止。
可以理解的是，在本申请的其他实施例中，第一锁止机构121可还包括安装基体，该安装基体上与支架本体110的通道116对应的位置可设置豁口。可将第一锁止件123和第二锁止件124先安装在安装基体上，然后将安装基体与第一锁止件123和第二锁止件124一同安装到支撑梁117的内部。
如图22和图23所示，在本申请的一种实施例中，电池200的锁止部211可包括锁销2111，该锁销2111的一端连接于箱体210的壳体，另一端用于与滑道16配合。
如图22和图23所示，锁止部211可还包括法兰2112，法兰2112通过锁紧螺钉2113安装在箱体210的壳体上，锁销2111上具有螺纹段，锁止销2111的一端依次穿过法兰2112及支撑梁117(未图示)的侧壁，并通过锁紧螺母2114锁紧在支撑梁117上。
在本申请的实施例中，第二锁止机构122的具体结构可与第一锁止机构121的上述结构相同，这里不在赘述。
在本申请的一种实施例中，支架100还可包括第一驱动件和第一联动件，第一联动件连接多个第一锁止机构121中的每个第二锁止件124，第一驱动件被配置为可通过第一联动件带动多个第一锁止机构121中的每个第二锁止件124同步动作，以使多个第一锁止机构121同步解锁。如此，多个第一锁止机构121可共用第一驱动件和第一联动件，相较于给每个第一锁止机构121设置一个第一驱动件的方案，本实施例共用第一驱动件的方案有利于降低成本，简化支架100的结构。
在本申请的一种实施例中，支架100还可包括第二驱动件和第二联动件，第二联动件连接多个第二锁止机构122中的每个第二锁止件124，第二驱动件被配置为可通过第二联动件带动多个第二锁止机构122中的每个第二锁止件124同步动作，以使多个第二锁止机构122同步解锁。如此，多个第二锁止机构122可共用驱动件和联动件，相较于给每个第二锁止机构122设置一个第二驱动件的方案，本实施例共用第二驱动件的方案有利于降低成本，简化支架100的结构。
以上仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
