本申请中出现的“多个”指的是两个以上(包括两个)，同理，“多组”指的是两组以上(包括两组)，“多片”指的是两片以上(包括两片)。
本申请实施例中，电池单体可以为二次电池，二次电池是指在电池单体放电后可通过充电的方式使活性材料激活而继续使用的电池单体。
电池单体包括但不限于锂离子电池、钠离子电池、钠锂离子电池、锂金属电池、钠金属电池、锂硫电池、镁离子电池、镍氢电池、镍镉电池、铅蓄电池等。
作为示例，电池单体可以为圆柱电池单体、棱柱电池单体、软包电池单体或其它形状的电池单体，棱柱电池单体包括方壳电池单体、刀片形电池单体、多棱柱电池，多棱柱电池例如为六棱柱电池等。
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。
在一些实施例中，电池可以为电池模块，电池单体有多个时，多个电池单体排列并固定形成一个电池模块。
在一些实施例中，电池可以为储能装置。储能装置包括储能集装箱、储能电柜等。
电池通常包括箱体、电池单体和热管理部件。电池单体容纳于箱体内，电池单体用于提供电能。热管理部件可以设置于箱体内，热管理部件用于管理电池单体的温度。
电池在使用时，需要将箱体置于车辆，并将电池单体和热管理部件均连接于车辆，以实现电池单体对车辆供电和通过车辆更新热管理部件内的流体以维持热管理部件的正常运行。电池单体与车辆的电连接以及热管理部件与车辆连接通常需要通过人为操作实现。需要人工将连接电池单体的电连接器和连接热管理部件的水连接器对接到车辆实现电池的更换。对于众多车辆而言，电池的更换效率关系着车辆的使用效率，影响用户体验。
以车辆为重卡为例，在将箱体固定到重卡上后，需要将连接电池单体的第一连接器与重卡连接，以及将连接热管理部件的第二连接器与重卡连接，由于电池单体和第一连接器之间通常用导线连接，热管理部件和第二连接器之间通常用管道连接，导线和管道均未固定，第一连接器和第二连接器的活动性较大，需要人工将两个接头连接到重卡上，降低了电池的换电效率，很难实现电池的快换。
为了改善电池换电效率低的问题，本申请实施例提供了一种电池，该电池设置有连接箱体的支架，将电连接电池单体的第一连接器和连接热管理部件的第二连接器设置于支架，并将第一连接器的至少部分和第二连接器的至少部分露出于箱体的外部。在箱体向连接车辆的连接器移动时，第一连接器和第二连接器可以跟随支架的移动直接与车辆的连接器对接，实现电池的快换，从而提高了电池的换电效率。
以下实施例为了方便说明，以车辆为例进行说明。

根据不同的电力需求，电池单体3的数量可以设置为任意数值。多个电池单体3可通过串联、并联或混联的方式连接以实现较大的容量或功率。由于每个电池10中包括的电池单体3的数量可能较多，为了便于安装，可以将电池单体3分组设置，每组电池单体3组成电池模块3a。电池模块3a中包括的电池单体3的数量不限，可以根据需求设置。电池10可以包括多个电池模块3a，这些电池模块3a可通过串联、并联或混联的方式进行连接。作为示例，如图2所示，箱体2内设置有多个电池模块3a，电池模块3a包括多个电池单体3，热管理部件4设置于箱体2内以管理电池单体3的温度。
热管理部件4可以为具有升温和降温功能的部件，当电池单体3组温度过高时，通过热管理部件4对电池单体3组进行降温，当电池单体3组温度过低时，通过热管理部件4对电池单体3组进行升温。热管理部件4可以在现有技术中选择，对于其现有的结构，此处不再赘述。通过热管理部件4调整电池单体3组的温度，使得电池单体3组能够在适合的环境中工作，提高电池10的工作效率以及电池10的可靠性。

第二连接器6的数量可以是一个，也可以是多个。若第二连接器6为一个，第二连接器6具有进水通道和出水通道，进水通道和出水通道均与热管理部件4连通，冷却液可以从进水通道流入热管理部件4内，冷却液流经热管理部件4后再从出水通道流出。若第二连接器6为多个，比如，第二连接器6为两个，两个第二连接器6分别为进水连接器和出水连接器，进水连接器具有进水通道，出水连接器具有出水通道，冷却液从进水连接器流入热管理部件4内，流经热管理部件4后再从出水连接器流出。
支架1可以与箱体2一体连接，比如，支架1可以焊接于箱体2；支架1也可以与箱体2可拆卸连接，比如，支架1通过锁附件与所述箱体2锁附连接，其中锁附件可以是螺栓、铆钉等。支架1可以位于箱体2的外部，也可以位于箱体2内。支架1的材质可以采用铜、铁、铝、不锈钢、铝合金等。支架1的材质可以与箱体2的材质相同，也可以与箱体2的材质不同。可以是支架1的强度高于箱体2的强度，也可以支架1的强度低于箱体2的强度。
上述实施例中，第一连接器5与箱体2内的电池单体3相连，第一连接器5可以外接车辆100的连接器，实现车辆100和电池10之间的电连接。第二连接器6与箱体2内的热管理部件4相连，第二连接器6可以外接车辆100的连接器，实现车辆100和热管理部件4之间的流体转换，以维持热管理部件4管理电池单体3的温度的有效性。第一连接器5和第二连接器6设置于支架1，且第一连接器5的至少部分和第二连接器6的至少部分位于箱体2的外部，在进行换电操作时，设置于支架1的第一连接器5和第二连接器6可以跟随支架1一同向车辆100的连接器移动，可以实现第一连接器5和第二连接器6直接与车辆100的连接器分别对接，减少了换电过程中的人为参与，实现第一连接器5和第二连接器6分别与车辆100的连接器的快换，从而提高了电池10的换电效率。
在一些实施例中，请参照图3和图4，图4为本申请一些实施例提供的电池10去除第二部分22的结构示意图。箱体2包括第一部分21和第二部分22，第一部分21和第二部分22共同限定出容纳空间2a，第一部分21和第二部分22沿第一方向X排布，第一部分21支撑第二部分22。其中，支架1连接于第一部分21，沿第一方向X，第一连接器5和第二连接器6连接于支架1背离第一部分21的一侧。
可以是第一部分21为板状结构，第二部分22为一侧开放的空心结构，第二部分22盖合在第一部分21上；也可以是第一部分21为一侧开放的空心结构，第二部分22为一侧具有开放结构的空心结构，第一部分21的开放侧面向第二部分22的开放侧相互盖合。
作为示例，如图3所示，沿第一方向X，第一部分21支撑第二部分22。第二部分22包括第一板件223、第一凸部221和两个第二凸部222，第一板件223连接第一部分21，第一凸部221和两个第二凸部222均设置于第一板件223并沿第三方向Z间隔排布，第一凸部221位于两个第二凸部222之间，第二凸部222具有用于容纳电池模块3a的容纳腔，支架1的至少一部分设置于第一凸部221内。其中，容纳腔为容纳空间2a的一部分；第一方向X平行于重力方向，第三方向Z为电池10的长度方向。
通过设置第一部分21和第二部分22沿第一方向X排布，且第一部分21支撑第二部分22，第一部分21可以承受第二部分22的重力，从而可以降低第二部分22的材料的强度需求，节约材料。通过设置支架1连接于第一部分21且第一连接器5和第二连接器连接于支架1背离第一部分21的一侧，在第一连接器5和第二连接器6对接车辆100的连接器时，由于第一连接器5的至少部分和第二连接器6的至少部分位于箱体2外部，第一连接器5的至少部分和第二连接器6的至少部分可以先接触车辆100的连接器，车辆100对第一连接器5和第二连接器6的反作用力可以通过支架1传递至第一部分21，降低第二部分22直接与车辆100接触而损坏的风险，提高电池10的可靠性。
此外，在电池10中，第二部分22可以主要起盖合作用，从而可以降低第二部分22的强度，增加起支撑作用的第一部分21的强度。将支架1连接第一部分21，支架1可以将受到的力直接传递至第一部分21，降低由于第二部分22强度不足而导致第二部分22受力损坏的风险。由于第一连接器5和第二连接器6设置于第一凸部221时，第一连接器5和第二连接器6受到的作用力直接传递给第一凸部221从而使第一凸部221受损，故将第一连接器5和第二连接器6设置于支架1可以降低第一凸部221受损的风险。
在一些实施例中，请继续参照图3和图4，沿第一方向X，第二部分22背离第一部分21的一侧设置有用于引出第一连接器5和第二连接器6的通孔2211，通孔2211与容纳空间2a连通，支架1封闭通孔2211。
可以是支架1位于容纳空间2a内，支架1封闭通孔2211，支架1上的第一连接器5和第二连接器6露出于通孔2211；也可以是支架1位于箱体2外，支架1封堵通孔2211；也可以是支架1的一部分位于容纳空间2a内，另一部分位于箱体2外，且第一连接器5和第二连接器6设置于支架1位于箱体2外的一部分。
通过设置通孔2211，第一连接器5和第二连接器6可以通过通孔2211与车辆100实现电连接和流体连通。通过设置支架1封闭通孔2211，可以在引出第一连接器5和第二连接器6时隔绝容纳空间2a和外部环境，降低外部环境对箱体2内的其它部件的影响。其中，其它部件可以是电池10内的控制单元、连接件、导线卡箍等。
在一些实施例中，请参照图3-图5，图5为本申请一些实施例提供的支架1和第一部分21的结构示意图。支架1包括第一连接部11、第二连接部12和支撑部13。第一连接部11连接于第一部分21，第一部分21容纳于容纳空间2a。第二连接部12与第一连接部11沿第一方向X相对设置，第一连接器5和第二连接器6均连接于第二连接部12，第二连接部12封闭通孔2211。支撑部13连接第一连接部11和第二连接部12。

第二连接部12可以呈板状，可以是第二连接部12抵接在第一凸部221面向第一部分21的表面，以封闭通孔2211；也可以是第二连接部12的一部分位于通孔2211内，另一部分抵接在通孔2211的孔壁上，以封闭通孔2211；也可以是第二连接部12全部位于通孔2211内，以封闭通孔2211。第二连接部12与第一连接部11相对设置，第二连接部12可以与第一连接部11平行设置。
支撑部13为支架1连接于第一连接部11和第二连接部12之间的部分。支撑部13可以呈板状、柱状等。支撑部13的数量可以是一个，也可以是多个。
作为示例，第一方向X可以是重力方向，第一连接部11位于第二连接部12的下方，第一连接部11安装于第一部分21的顶部，第二连接部12封闭第二部分22的通孔2211，第一连接器5和第二连接器6均设置于第二连接部12并凸出于箱体2的外部。在将电池10与车辆100对接时，可以从下向上移动箱体2，使得第一连接器5和第二连接器6与车辆本体相对应的连接器对接，第一连接器5和第二连接器6分别将车辆100的施加的力通过支架1传递至第一部分21，降低第二部分22接触车辆本体而损坏的风险，提高了电池10的结构稳定性。
通过将第一连接部11连接第一部分21、第二连接部12封堵通孔2211，可以将支架1设置于箱体2内，减少支架1和箱体2占用的空间。通过设置第一连接器5和第二连接器6均连接于第二连接部12且第二连接部12封堵第二部分22上的通孔2211，第一连接器5和第二连接器6安装时受到的力均可以通过支架1传递至第一部分21，从而降低第二部分22受力被破坏的风险。
在一些实施例中，沿第一方向X，第二连接部12背离第一连接部11的一侧形成有第一表面121，第一表面121用于与第二部分22抵接，第一表面121设置有凸起122，凸起122至少部分延伸至通孔2211内，第一连接器5和第二连接器6设置于凸起122。
可以是第一表面121的全部与第二部分22抵接；也可以是第一表面121的一部分与第二部分22抵接，另一部分位于通孔2211内。
可以是凸起122全部位于通孔2211内，第一连接器5和第二连接器6设置于凸起122内且穿过通孔2211；也可以是凸起122的仅一部分位于通孔2211内，第一连接器5和第二连接器6设置于凸起122位于通孔2211内的部分且穿过通孔2211。
作为示例，请继续参照图3和图4，凸起122的全部位于通孔2211内，第一表面121设置有第一安装孔1211，第一凸部221上设置有第二安装孔2212，螺栓穿过第一安装孔1211和第二安装孔2212以锁附第二连接部12和第一凸部221。
通过将第一表面121与第二部分22抵接，可以提高第二连接部12和第二部分22的连接稳定性。通过在第一表面121上设置凸起122且凸起122的至少部分延伸至通孔2211内，可以通过凸起122和通孔2211对第二部分22进行定位，便于第一部分21和第二部分22的安装，提高了箱体2的安装效率。通过将第一连接器5和第二连接器6设置于凸起122，使得第一连接器5和第二连接器6可以更加凸出于背离第一部分21的一侧，便于第一连接器5和第二连接器6分别与车辆100的连接器的配合。
在一些实施例中，沿第一方向X，支架1具有最远离第一部分21的第二表面 1221，第一连接器5和第二连接器6均凸出于第二表面1221。其中，第二表面1221呈矩形，矩形的对角线经过第一连接器5和第二连接器6，对角线的中点位于第一连接器5和第二连接器6之间。
在第二连接部12的第一表面121设置有凸起122的实施例中，可以是凸起122背离第一表面121的一端的端面为第二表面1221。在第二连接器6的第一表面121没有设置凸起122的实施例中，第二表面1221可以是第一表面121。
对角线的中点位于第一连接器5和第二连接器6之间，即第一连接器5和第二连接器6沿对角线的延伸方向分别位于对角线的中点的两侧。
作为示例，沿对角线的延伸方向，第一连接器5与对角线的一端(对角线靠近第一连接器5的一端)的最小距离为第一距离，第二连接器6与对角线的另一端(对角线靠近第二连接器6的一端)的最小距离为第二距离，第一连接器5与第二连接器6的最小距离为第三距离，第一距离与第二距离之和小于第三距离。这种结构使得第一连接器5和第二连接器6分别位于矩形的对角附近，进一步增大了第一连接器5和第二连接器6之间的距离。
通过设置第二表面1221呈矩形且矩形的对角线的中点位于第一连接器5和第二连接器6之间，使得第一连接器5和第二连接器6处于相对较远的距离，降低第一连接器5和第二连接器6之间的干扰的风险，有利于第一连接器5和第二连接器6与车辆100的连接器配合更加稳定。
在一些实施例中，请参照图6，图6为本申请一些实施例提供的支架1的结构示意图。支架1包括第一连接部11、第二连接部12和支撑部13。第一连接部11连接于箱体2沿第一方向X的一侧。第二连接部12与第一连接部11沿第一方向X相对设置，第一连接器5和第二连接器6均连接于第二连接部12。支撑部13连接第一连接部11和第二连接部12。

第一方向X可以是重力方向，在安装电池10时，可以是第一连接部11位于第二连接部12的下方，可以从下向上移动箱体2，使得第一连接部11和第二连接部12与车辆本体相对应的连接器对接，第一连接部11和第二连接部12分别将车辆100的施加的力通过支架1传递至箱体2，降低箱体2损坏的风险。
第一连接部11和第二连接部12沿第一方向X相对设置是指第一连接部11和第二连接部12在第一方向X上具有间隙，且第一连接部11和第二连接部12沿第一方向X上的投影至少部分重叠。
通过设置第一连接部11，第一连接部11可以连接箱体2，通过设置支撑部13和第二连接部12，支撑部13可以支撑第二连接部12，通过将第一连接器5和第二连接器6设置于第二连接部12，第一连接器5的至少部分和第二连接器6的至少部分固定在箱体2的外部，使得电池10对接车辆100时，第一连接器5和第二连接器6受到 的力可以通过第二连接部12、支撑部13和第一连接部11传递至箱体2，降低箱体2接触车辆100而受损的风险，且第一连接器5的至少部分和第二连接器6的至少部分位于箱体2的外部，在箱体2向车辆100移动时，支架1可以携带第一连接器5和第二连接器6移动，便于第一连接器5和第二连接器6的快换。

通过设置加强件14，可以增加第一连接部11的强度，降低第一连接部11被破坏的风险。
在一些实施例中，加强件14设置于第一连接部11背离第二连接部12的一侧，加强件14连接第一连接部11和箱体2。
作为示例，如图7所示，第一方向X平行于支架1的重力方向，加强件14与第一连接部11连接并位于第一连接部11的下方。
通过将加强件14设置在第一连接部11和箱体2之间，加强件14可以加强第一连接部11和箱体2之间的连接，降低第一连接部11脱离箱体2的风险。
在一些实施例中，加强件14的内部设置有空腔141。
空腔141的数量可以是一个，也可以是多个。比如，空腔141的数量为多个，多个空间间隔设置。空腔141可以贯穿加强件14的外表面，空腔141也可以完全密封于加强件14内。
通过在加强件14的内部设置空腔141，空腔141可以减少加强件14的耗材，减轻加强件14的质量，节约成本。在加强件14设置于第一连接部11和第一部分21之间时，支架1可以通过加强件14对第一部分21传导力，加强件14的空心结构有助于增加支架1对第一部分21的缓冲作用，降低第一部分21受损的风险。
在一些实施例中，空腔141沿第二方向Y贯穿加强件14，第二方向Y垂直于第一方向X。
作为示例，如图7所示，第一方向X为支架1的重力方向，第二方向Y为支架1的宽度方向，第三方向Z为支架1的长度方向，空腔141沿支架1的宽度方向贯穿加强件14。
通过沿第二方向Y贯穿加强件14，进一步减轻的加强件14的质量，降低了空腔141的加工难度，便于通过空腔141实现加强件14的转移。
在一些实施例中，请继续参照图7。第一连接部11包括连接区111和安装 区112。加强件14和支撑部13均连接于连接区111。安装区112与连接区111相连，且位于连接区111沿第三方向Z的至少一侧，安装区112用于安装其他部件，第三方向Z垂直于第一方向X。

通过将加强件14和支撑部13均连接于连接区111，通过连接区111实现了加强件14和支撑部13之间的连接，通过设置安装区112，安装区112也连接于箱体2，安装区112可以安装其他部件，从而提高第一连接部11的利用率，增大第一连接部11和箱体2的接触面积，提高第一连接部11和箱体2的连接稳定性。
在一些实施例中，支撑部13为多个，多个支撑部13间隔设置于第一连接部11和第二连接部12之间。
作为示例，请继续参照图7，支撑部13的数量为四个，四个支撑部13分别连接连接区111和第二连接部12。
通过设置多个支撑部13，多个支撑部13均可以将车辆100施加给第一连接器5和第二连接器6的力传递至第二连接部12后通过支撑部13传递至第一连接部11，分散单个支撑部13所需承受的压力，降低支架1倍破坏的风险，使得第一连接部11和第二连接部12之间的连接更加稳定。
在一些实施例中，请参照图8，图8为本申请再一些实施例提供的支架1的结构示意图。第二连接器6与热管理部件4通过第一管道7连通，安装区112设置有供第一管道7穿过的孔部1121。

通过设置第一管道7，并在安装区112设置孔部1121，孔部1121可以限制第一管道7的位置，从而提升第一管道7的稳定性，降低第一管道7被破坏的风险。
在一些实施例中，请参照图9，图9为本申请另一些实施例提供的支架1的结构示意图。第一连接部11包括两个安装区112，沿第三方向Z，两个连接区111分别位于加强件14的两侧。
作为示例，如图9所示，第二连接器6为两个，分别为进水连接器和排水连接器，进水连接器和排水连接器分别连接有一个第一管道7，安装区112的数量为两 个，两个安装区112分别设置于连接区111沿第三方向Z的两侧，两个安装区112上分别设置有孔部1121，两根第一管道7分别穿设于两个孔部1121，实现与箱体2内的热管理部件4连通。
通过设置两个安装区112，增大了安装其他部件的区域面积，提升了第一连接部11和箱体2的接触面积，提高了第一连接部11的实用性。
在一些实施例中，请继续参照图9。沿第一方向X，第一连接部11的投影完全覆盖第二连接部12。
可以是第一连接部11沿第一方向X的投影和第二连接部12沿第一方向X的投影完全重合，也可以是仅一部分第一连接部11沿第一方向X的投影和第二连接部12沿第一方向X的投影完全重合。
通过沿第一方向X设置第一连接部11的投影完全覆盖第二连接部12，第一连接部11与箱体2的接触面积可以大于或等于第二连接部12与车辆100的接触面积，提升支架1的稳定性。
在一些实施例中，沿第一方向X，第一连接部11的投影面积大于第二连接部12的投影面积。
作为示例，如图9所示，沿第一方向X，第一连接部11的投影面积大于第二连接部12的投影面积。沿第一方向X，两个安装部的投影的至少一部分露出于第二连接部12，以便于在安装其它部件时，第二连接部12让位于其它部件，降低第二连接部12受损时破坏其它部件的风险。
通过沿第一方向X设置第一连接部11的投影面积大于第二连接部12的投影面积，沿垂直于第一方向X的方向，第一连接部11的一部分露出于第二连接部12，便于安装其他部件，提高第一连接部11的利用率。
在一些实施例中，支架1与箱体2可拆卸连接。
支架1与箱体2可以通过多种连接方式实现可拆卸，比如，支架1与箱体2通过锁附件连接，锁附件可以是螺钉、螺栓等，再如，支架1与箱体2卡接。
支架1可以与箱体2的第一部分21可拆卸连接，也可以与箱体2的第二部分22可拆卸连接。
作为示例，请参照图3和图9所示，支架1与箱体2的第一部分21可拆卸连接。具体地，支架1的第一连接部11位于箱体2的第一部分21的顶部，第一连接部11设置有第三安装孔113，第三安装孔113用于通过螺栓将第一连接部11与第一部分21可拆卸连接。支架1的第二连接部12连接箱体2的第二部分22且第二连接部12的至少部分露出于第二部分22的通孔2211处，第二连接部12的周向设置有第一安装孔1211，第二部分22的第一凸部221设置有第二安装孔2212，第二安装孔2212周向设置于通孔2211，第一安装孔1211和第二安装孔2212用于通过螺栓可拆卸连接第二连接部12和第二部分22。
通过可拆卸连接支架1和箱体2，便于支架1和箱体2的维修和替换，提高支架1或箱体2的使用寿命。
本申请实施例提供一种车辆100，包括车辆本体和上述任意一个实施例提供 的电池10，第一连接器5和第二连接器6均与车辆本体连接，以使电池10与车辆本体电连接，并使电池与车辆本体流体连通。
在一些实施例中，请参照图10，图10为本申请一些实施例提供的电池10与横梁40的结构示意图。车辆本体还包括横梁40。作为示例，如图10所示，横梁40的数量为两根，两根横梁40均沿第二方向Y延伸，两个横梁40分别穿设于第一凸部221和两个凸部之间的两个间隙处，以固定电池10。
请参照图3-图7，本申请实施例提供一种电池10，该电池10包括箱体2、电池单体3、热管理部件4、第一连接器5、第二连接器6和支架1。电池单体3和热管理部件4均容纳于箱体2内。箱体2包括第二部分22和支撑第二部分22的第一部分21。支架1包括第一连接部11、第二连接部12和支撑部13，支撑部13连接第一连接部11和第二连接部12并支撑第二连接部12。第一连接部11设置于第一部分21的顶部。第二部分22设置有第一凸部221，第一凸部221的顶部设置有通孔2211，第二连接部12连接第一凸部221；第一连接器5和第二连接器6均设置于第二连接部12，第一连接器5和第二连接器6穿设于通孔2211且第一连接器5的一部分和第二连接器6的一部分位于箱体2的外部。在电池10连接至车辆本体时，第一连接器5和第二连接器6可以跟随支架1的移动先对接车辆本体上对应的连接器，车辆本体反作用力至第一连接器5和第二连接器6，第一连接器5和第二连接器6将受到车辆本体的力传递至支架1，再由支架1传递至第一部分21。
通过在第一部分21的顶部设置支架1并将第一连接器5的至少部分和第二连接器6的至少部分设置于箱体2的外部，在箱体2向上移动靠近车辆本体时，第一连接器5和第二连接器6可以优先接触车辆本体，以便于支架1上的第一连接器5和第二连接器6可以直接与车辆本体对接，实现车辆本体和电池10的电连接和流体通道的连通。在支架1不被破坏的情况下，第二部分22未接触车辆本体，第二部分22仅会受到由于支架1的形变产生的向下的力，降低了第二部分22受损的风险。在进行换电操作时，设置于支架1的第一连接器5和第二连接器6可以跟随支架1一同向车辆本体的连接器移动，可以实现第一连接器5和第二连接器6直接与车辆本体的连接器分别对接，减少了换电过程中的人为参与，实现第一连接器5和第二连接器6分别与车辆本体的连接器的快换，从而提高了电池10的换电效率。
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。
