在本申请中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“附接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。

本申请中出现的“多个”指的是两个以上(包括两个)。
本申请中，电池单体可以包括锂离子二次电池单体、锂离子一次电池单体、锂硫电池单体、钠锂离子电池单体、钠离子电池单体或镁离子电池单体等，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、方形电池单体和软包电池单体，本申请实施例对此也不限定。

电池应用于用电装置时，通常安装在用电装置的安装座上，安装座用于对电池提供支承，并实现电池与用电装置内的相关功能模块电连接。
发明人发现电池在安装在用电装置的安装座后，安装座对电池的支承结构出现损坏的几率较大的问题后，便对用电装置的安装座的结构及安装座与用电装置的装配方式进行了系统地分析研究。结果发现，电池安装在安装座上后，安装座对电池的支承方式为悬臂支承，用电装置在使用的过程中，电池受到的冲击、振动等载荷传递到安装座，而安装座对电池的悬臂支承方式，使得安装座承受较大的弯曲载荷，如此极大地降低了安装座的承载能力，在频繁的冲击、振动等载荷的作用下，安装座容易出现支承失效甚至损坏的风险，如此，严重影响了安装座的使用寿命，并引发电池脱离安装座的风险。
基于发明人发现的上述问题，发明人对安装座的结构进行了改进，本申请实施例描述的技术方案适用于安装座以及使用安装座的用电装置。

以下实施例为了方便说明，以用电装置为车辆为例进行说明。
图1为本申请一些实施例提供的车辆1的结构示意图。如图1所示，车辆1的内部设置有电池2。
电池2可以设置在车辆1的底部或头部或尾部。电池2可以用于车辆1的供电，例如，电池2可以作为车辆1的操作电源。
车辆1还可以包括控制器11和马达12，控制器11用来控制电池2为马达12供电，例如，用于车辆1的启动、导航和行驶时的工作用电需求。
在本申请一些实施例中，电池2不仅仅可以作为车辆1的操作电源，还可以作为车辆1的驱动电源，代替或部分地代替燃油或天然气为车辆1提供驱动动力。
图2为本申请一些实施例提供的电池2的爆炸示意图。如图2所示，电池2包括箱体21和电池单体(未示出)，电池单体容纳于箱体21内。
箱体21用于容纳电池单体，箱体21可以是多种结构。在一些实施例中，箱体21可以包括第一部分211和第二部分212，第一部分211与第二部分212相互盖合，第一部分211和第二部分212共同限定出用于容纳电池模块3的容纳腔21a。第一部分211可以是一端开口的空心结构，第二部分212为板状结构，第二部分212盖合于第一部分211的开口侧，以形成具有容纳腔21a的箱体21；第一部分211和第二部分212也均可以是一侧开口的空心结构，第一部分211的开口侧盖合于第二部分212的开口侧，以形成具有容纳腔21a的箱体21。当然，第一部分211和第二部分212可以是多种形状，比如，圆柱体、长方体等。
当第一部分211盖合于第二部分212的顶部，第一部分211亦可称之为上箱盖，第二部分212亦可称之为下箱体21。
在电池2中，电池单体可以是一个，也可以是多个。若电池单体为多个，多个电池单体之间可串联或并联或混联，混联是指多个电池单体中既有串联又有并联。多个电池单体之间可直接串联或并联或混联在一起，再将多个电池单体构成的整体容纳于箱体21内；当然，也可以是多个电池单体先串联或并联或混联组成电池模块3，多个电池模块3再串联或并联或混联形成一个整体，并容纳于箱体21内。
图3为图2所示的电池模块3的的结构示意图。
在一些实施例中，如图3所示，电池单体31为多个，多个电池单体31先串联或并联或混联组成电池模块3。多个电池模块3再串联或并联或混联形成一个整体，并容纳于箱体内。
电池模块3中的多个电池单体31之间可通过汇流部件实现电连接，以实现电池模块3中的多个电池单体31的并联或串联或混联。
如图4至图6所示，根据本申请实施例提供的用电装置的安装座4用于安装电池2，安装座4包括座本体41、支承组件42以及锁止机构43。支承组件42设置于座本体41，支承组件42包括间隔设置的第一支承座421和第二支承座422。锁止机构43设置于座本体41，锁止机构43包括锁止轴431，锁止轴431用于穿过电池2的伸入第一支承座421和第二支承座422之间的部分，并支承于第一支承座421和第二支承座422，以将电池2固定。
具体地，安装座4安装在用电装置上，用于承载电池2，并对电池2进行定位。此外，安装座4上还可以集成有其它功能模块，以实现电池2与相关功能模块的电连接，进而实现电池2正常为用电装置提供电能。安装座4的具体结构型式不做限定，只要能够用于安装电池2即可。以用电装置为车辆为例，安装座4可固定在车辆的底盘上。
座本体41可以是与用电装置连接并集成有控制元件等功能模块的结构，其可以呈板状结构，也可以由杆状结构拼接而成，可以根据具体的应用需求进行选取。
在将电池2安装于安装座4后，电池2直接支承于锁止机构43的锁止轴431上，而锁止轴431支承于支承组件42的第一支承座421和第二支承座422之间，且锁止轴431对电池2的支承部位位于第一支承座421和第二支承座422之间。如此，锁止轴431对电池2的支承点两侧均得到有效的支承，相当于锁止轴431得到了双点支承，相比于锁止轴431的悬臂支承，即锁止轴431对电池2支承部位仅一侧得到有效支承、而另一侧悬空的技术方案，双点支承的技术方案，在同样的冲击、振动等载荷作用下，支承组件42对锁止轴431双点支承的方式，可以使锁止轴431承受更小的弯曲载荷。
第一支承座421和第二支承座422分别具有支承面，具体地，支承面为与锁止轴431配合的面，支承面可以一个平面、曲面或者是一个柱面，可以根据实际需求进行选取。第一支承座421和第二支承座422可以分别独立地设置于座本体41，也可以将二者连接为整体后再设置于座本体41。
锁止轴431穿过电池2的方式，可以是锁止轴431穿过电池2的封闭结构设置，比如，穿过电池2的封闭的柱面，也可以是锁止轴431穿过电池2的半封闭结构设置，比如，穿过电池2的半封闭的半柱面，具体可以根据实际需要进行选取。
可选地，可以在电池2靠近安装座4的一侧设置锁止件22，锁止轴431穿电池2的锁止件22设置。
锁止轴431对电池2的支承可以是线接触，也可以是面接触。锁止轴431对电池2的支承位置距离第一支承座421和第二支承座422的距离可以相同，也可以不相同。可以理解的是，锁止轴431对电池2的支承位置位于第一支承座421和第二支承座422中间时，锁止轴431两侧承受的弯矩较为接近，如此，在同样的外部载荷作用下，锁止轴431承受的弯曲载荷最小。
本申请实施例提供的安装座4，通过设置支承组件42包括第一支承座421和第二支承座422共同支承锁止轴431，而锁止轴431对电池2的支承位置设置在第一支承 座421和第二支承座422之间，如此，在同样的冲击、振动等载荷作用下，锁止轴431承受的弯矩较小，提高锁止轴431的承载能力，进而提高安装座4的使用寿命。
第一支承座421和第二支承座422对锁止轴431的支承方式可以是面接触、线接触等，示例性地，锁止轴431与第一支承座421或第二支承座422的接触部位呈圆柱形，则对应的第一支承座421或第二支承座422的部位可以呈平面、与锁止轴431配合的半封闭的半圆柱面或者与锁止轴431配合的封闭的圆柱面等。这里不做限制，可以根据实际需求进行选取。
在一些可选的实施例中，如图7所示，第一支承座421具有第一支承孔421a，第一支承孔421a用于穿设锁止轴431。
可以理解的是，在用电装置工作过程中，电池2受的冲击、振动载荷的方向可能会朝向各个方向，如此电池2对锁止轴431、锁止轴431对第一支承座421的载荷的方向也可能朝向各个方向。通过设置第一支承座421具有第一支承孔421a，使得第一支承座421能够承受锁止轴431对第一支承座421的各个方向的载荷，如此可以进一步提高安装座4的承载能力。
在一些实施例中，请继续参阅图7，第二支承座422具有第二支承孔422a，第二支承孔422a用于穿设锁止轴431。
同第一支承座421设置第一支承孔421a一样，设置第二支承座422具有第二支承孔422a，可以进一步使得第二支承座422能够承受各个方向载荷，进而提高安装座4的承载能力。
在一些实施例中，如图8和图9所示，锁止轴431具有倾斜段4311，沿锁止轴431的伸出方向，倾斜段4311朝靠近电池的方向倾斜设置，倾斜段4311用于与电池的楔块221相互配合。
具体地，本文所述的锁止轴431的伸出方向，即锁止轴431伸出后，可以穿设于电池，并支承在第一支承座421和第二支承座422的方向。楔块221可以是形成在电池与锁止轴431相配合的锁止件22内、并用于与倾斜段4311相配合的块体，楔块221的倾斜方向与倾斜段4311的倾斜方向相反，以使两者能够较好地贴合。
可以理解的是，由于锁止轴431与电池的加工精度偏差，在锁止轴431穿设于电池后，并不能保证锁止轴431与电池的良好贴合。而设置锁止轴431的倾斜段4311与电池的楔块221配合，可以在将锁止轴431沿伸出方向穿设于电池的过程中，根据实际需要设置锁止轴431的具体伸出长度和距离，以保证锁止轴431与电池的良好配合。如此，有利于降低对电池与锁止轴431相互配合部位的加工精度的要求，降低生产成本。
倾斜段4311可以整体成型设置，并设置倾斜段4311具有合适的倾斜角度。
在一些可选的实施例中，请继续参阅图8至图10，倾斜段4311包括第一子段431a和第二子段431b，第一子段431a和第二子段431b呈阶梯分布。
具体地，第一子段431a和第二子段431b对应的表面可以相互平行，也可以设置不同的倾斜角度。设置第一子段431a和第二子段431b呈阶梯设置，可以在第一子段431a无法与楔块221配合的情况下，沿锁止轴431的伸出方向移动较小的距离即可实 现第二子段431b与楔块221的配合。如此设置，可以有效地降低电池2的安装难度。
在需要对电池定位时，可以设置锁止轴431沿伸出方向伸出运动，以使锁止轴431穿设于电池，而在需要将电池从用电装置上拆卸下来时，则需要设置锁止轴431缩回，以解除对电池的锁止作用。锁止轴431的伸出运动可以通过人工实现，也可以通过机械的方式实现，这里不做限制，可以根据实际需求进行选取。
在一些实施例中，锁止机构43还包括连接于锁止轴431的驱动部件432，驱动部件432用于驱动锁止轴431运动。
具体地，驱动部件432用于驱动锁止轴431沿伸出方向伸出运动，以实现对电池的锁止件22的定位。在需要将电池从安装座4上拆卸下来时，则可以通过驱动组件带动锁止轴431缩回运动，以将电池从安装座4上解锁。设置驱动部件432驱动锁止轴431运动，使得锁止轴431的运动更加省力方便。
可以理解的是，驱动部件432可以是气缸、液压缸或者电机等结构。示例性低，驱动部件432为液压缸，锁止轴431连接于活塞杆，通过活塞杆的伸出或者缩回运动，实锁止轴431对电池的定位或者解除定位。
锁止轴431可以裸露在外部环境中，也可以设置防护装置罩设在锁止轴431上，以对锁止轴431进行防护。
在一些可选的实施例中，锁止机构43还包括套筒433，套筒433套设于锁止轴431，且锁止轴431能够伸出套筒433。
具体地，锁止轴431在不需要对电池进行支承限位时，便缩回到套筒433内，而需要对电池进行支承时，便从套筒433中伸出。通过设置套筒433，可以对锁止轴431进行防护，降低外界的颗粒、粉尘等渗入锁止轴431的伸缩副，进而造成锁止轴431卡滞的风险。且套筒433在锁止轴431的运动过程中，可以为锁止轴431的运动提供导向，降低锁止轴431发生偏斜的风险。
套筒433可以与第一支承座421和第二支承座422分别独立设置，也可以相互连接设置，这里不做限制。
在一些可选的实施例中，第一支承座421连接于套筒433，第二支承座422连接于第一支承座421。
如此设置，可以将第一支承座421、第二支承座422以及套筒433一起连接后再设置于座本体41，提高安装座4内部结构的整体性，且设置三者连接，可以提高锁止轴431的运动精度，提高锁止轴431与电池的配合精度。
根据安装座4对电池的支承方式不同，安装座4可以包括一个或者多个锁止机构43，安装座4包括多个锁止机构43的实施例中，多个锁止机构43以呈多种分布形式，比如，可以分布呈一行、两行甚至更多行。可以根据实际需求的安装座4对电池的承载能力进行具体设置。
在一些实施例中，如图11和图12所示，安装座4包括多个锁止机构43，多个锁止机构43间隔设置于座本体41。
可以理解的是，在电池的重量不变的情况下，设置多个锁止机构43可以将电池对安装座4的载荷在多个锁止机构43上进行分配，从而降低单个锁止机构43承受的 电池的载荷，如此设置，可以提高安装座4的承载能力，进而提高安装座4的使用寿命。
在一些实施例中，电池沿第一方向X支承与安装座4，电池具有沿第二方向Y相对设置的第一表面以及沿第三方向Z设置的第二表面，第一表面连接两个第二表面。第一方向X、第二方向Y以及第三方向Z两两垂直。
具体地，第一方向X可以为铅垂方向，第二方向Y和第三方向Z可以为水平方向。锁止轴431可以沿第二方向Y伸出运动，也可以沿第三方向Z伸出运动，或者沿其它方向伸出运动。而在安装座4包括多个锁止机构43时，多个锁止机构43可以沿第二方向Y间隔设置，也可以沿第三方向Z间隔设置，或者锁止机构43成对设置，分别设置于电池沿第二方向Y或者沿第三方向Z的两侧。
在一些可选的实施例中，安装座4包括两个锁止机构43，两个锁止机构43沿第二方向Y间隔设置。锁止轴431的轴向沿第二方向Y设置，且两个锁止轴431的伸出方向相反。
如此设置，可以使得两个锁止机构43对电池的支承力相对于电池的重心尽可能地对称设置，提高电池在安装座4上的受力平衡性，并降低电池受到的倾覆力矩。
在另一些实施例中，安装座4包括多对锁止机构43，每一对锁止机构43沿第二方向Y间隔设置，且多对锁止机构43沿第三方向Z间隔设置，锁止轴431的轴向沿第二方设置，且每一对锁止机构43的锁止轴431的伸出方向相反。
需要说明的是，每一个锁止机构43均对应一个支承组件42，设置多对锁止机构43，对应地，需要设置多对支承组件42，以对每一个锁止机构43的锁止轴431进行支承。
可以理解的是，设置安装座4包括多对锁止机构43，可以提高安装座4对电池的承载能力，降低每一个锁止机构43的锁止轴431的受力。而设置多对锁止机构43伸出方向相反，有利于提高电池的受力平衡性。
在一些实施例中，安装座4还包括设置于座本体41的导向定位机构44。导向定位机构44用于引导电池移动并对电池定位。
可以理解的是，在将锁止轴431穿设于电池的步骤之前，需要对电池进行定位，以保证电池在安装座4的位置为预设位置，保证电池安装位置的准确性。因此，设置导向定位机构44，可以在将电池放置在安装座4的过程中，即可引导电池的走向，降低电池放置在安装座4后对电池的位置进行反复调整的现象。而在电池放置到位后，导向定位机构44对电池进行简单的定位，降低电池放置在安装座4后引起位移偏差的风险。因此，设置导向定位机构44可以有效地提高电池的安装精度和安装效率。
导向定位机构44的具体结构不做限制，只要能够为电池的运动提供导向，并在电池放置到位后，对电池具有一定的定位作用即可。
在一些可选的实施例中，导向定位机构44包括导向件441和定位销442。导向件441具有导向面441a，导向面441a用于引导电池移动。定位销442用于与电池的定位孔配合，以对电池定位。
具体地，导向面441a可以为沿朝向安装座4的方向倾斜设置的斜面。在电池朝 向安装座4运动的过程中，可以与导向面441a接触，并沿导向面441a运动。在电池沿导向面441a移动的过程中，电池的定位孔逐渐与定位销442配合，在电池运动到位后，定位销442起到对电池进行定位的作用。因此，设置导向定位机构44包括导向件441和定位销442，通过简单的结构即可完成电池安装过程中的导向的定位作用。
导向件441和定位销442的数量不做限制。示例性地，可以在电池与安装座4相对的四条边对应的位置均设置导向件441，并在电池与安装座4相对的对角线上设置两个定位销442，如此对电池的导向导向作用更加精准，进一步提高电池的安装效率。
根据本申请实施例提供的用电装置，包括电池以及上述任意一实施例提供的安装座4。电池的一部分伸入第一支承座421和第二支承座422之间，锁止轴431穿过电池的伸入第一支承座421和第二支承座422之间的部分并支承与第一支承座421和第二支承座422，以将电池固定。
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换，但这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
