Description

发电系统和具有该发电系统的移动充电车 技术领域
本发明属于配电技术领域，具体提供一种发电系统和具有该发电系统的移动充电车。
背景技术
随着市场上电动汽车数量的日益增加，现有的充电站、换电站、充换电站已不能满足电动汽车的日常所需。尤其是电动汽车在行驶的路途上电能耗尽时，需要借助其他车辆将其托运至充、换电站处，才能进行充电或换电。
为了解决该问题，市场上推出了移动充电车，用于充当临时的充电站。目前，配置有发电系统的移动充电车，通常是通过安装在车厢内部的整套柴油发电机组(柴油发动机+发电机)来进行发电。受限于较小的车厢空间和较小的整车载重，移动充电车上不能安装体积和重量较大的发电机组。换句话说，移动充电车上不能安装发电功率较大的发电机组。因此，目前市场上的移动充电车的发电功率均比较小。
随着电动汽车快充技术的发展，现有的移动充电车已不能满足电动汽车的充电需求。
相应地，本领域需要一种新的发电系统和具有该发电系统的移动充电车来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有移动充电车的车载发电系统发电功率较低不能满足电动汽车充电需求的问题，本发明提供了一种发电系统，所述发电系统应用于车辆，所述车辆包括发动机和驱动桥，所述发电系统包括发电机以及将所述发动机和所述发电机驱动连接的连接装置，所述连接装置能够使所述发动机选择性地与所述发电机和/或所述驱动桥驱动连接。
在上述发电系统的优选技术方案中，所述连接装置包括分动箱，所述分动箱包括：
箱体；
输入轴，其枢转地设置在所述箱体上并与所述发动机的输出轴驱动连接；
第一输出轴，其枢转地设置在所述箱体上并与所述发电机的转轴驱动连接；
第二输出轴，其枢转地设置在所述箱体上并与所述驱动桥驱动连接；
其中，所述输入轴能够选择性地与所述第一输出轴或所述第二输出轴驱动连接。
在上述发电系统的优选技术方案中，所述分动箱还包括与所述输入轴同轴固定的输入齿轮、与所述第一输出轴同轴固定的第一输出齿轮和与所述第二输出轴同轴固定的第二输出齿轮；所述第一输出齿轮和所述第二输出齿轮在轴向上错位设置；所述输入齿轮能够沿轴向滑动并因此能够选择性地与所述第一输出齿轮或所述第二输出齿轮啮合。
在上述发电系统的优选技术方案中，所述分动箱还包括可滑动地设置在所述箱体上的驱动机构，所述驱动机构能够拨动所述输入齿轮，并因此使所述输入齿轮选择性地与所述第一输出齿轮或所述第二输出齿轮啮合。
在上述发电系统的优选技术方案中，所述输入轴上沿轴向设置有相邻的第一挡块和第二挡块，所述驱动机构包括位于所述第一挡块和所述第二挡块之间的拨叉以及与所述拨叉固定连接或一体制成的把手，通过操作所述把手能够使所述拨叉选择性地推动所述第一挡块或所述第二挡块，并因此使所述输入齿轮沿轴向移动。
在上述发电系统的优选技术方案中，所述发动机匹配有第一输出轴和第二输出轴，所述连接装置包括与所述第一输出轴驱动连接的第一离合器和与所述第二输出轴驱动连接的第二离合器，所述第一离合器远离所述发动机的一端与所述发电机驱动连接，所述第二离合器远离所述发动机的一端与所述车辆的驱动桥驱动连接。
在上述发电系统的优选技术方案中，所述第一输出轴和所述第二输出轴都设置在所述发动机上，或者所述第一输出轴和所述第二输出轴都设置在与所述发动机驱动连接的分动器上；并且/或者，所述第一离合器和/或所述第二离合器是电磁离合器或气动离合器。
在上述发电系统的优选技术方案中，所述驱动桥包括所述车辆的前桥和/或后桥。
在上述发电系统的优选技术方案中，所述发电系统还包括变速箱，所述变速箱的输入轴与所述发动机驱动连接，所述变速箱的输出轴与所述连接装置驱动连接。
此外，本发明还提供了一种移动充电车，所述移动充电车包括上述发电系统的优选技术方案中任一项所述的发电系统。
本领域技术人员能够理解的是，在本发明的优选技术方案中，通过使发动机选择性地与发电机或车辆的驱动桥驱动连接，使得发动机能够驱动车辆行走并在车辆停车时驱动发电机转动，使发电机为待充电的电动汽车提供充电服务。由于驱动车辆行走的发动机的输出功率大于现有技术中车载的、为发电机单独配置的发动机的输出功率，所以本发明的发动机能够驱动更大发电功率的发电机，使发电机输出的电流和电压能够满足待充电的电动汽车的正常所需。
需要说明的是，在本发明的优选实施方案中，上述的车辆指的是移动充电车。
进一步，本发明通过在变速箱的输出端连接一个分动箱，并使分动箱的第一输出轴连接发电机，使分动箱的第二输出轴连接移动充电车的驱动桥，使得发动机输出的扭矩能够通过分动箱选择性地传递给发电机或驱动桥。因此，本发明的移动充电车与现有技术中的移动充电车相比，不再需要为发电机配置单独的发动机，减小了移动充电车的整体重量。并且，本发明的移动充电车还可以通过变速箱调节分动箱的第一输出轴输出的转速，进而调节发电机的输出功率。进一步，本发明的分动箱可以被设置在移动充电车的前舱内，也可以被设置在移动充电车的底盘的下侧，因此本发明的移动充电车还节约了内部空间。
在本发明另一个可行的实施例中，发动机还可以在驱动移动充电车行走的同时驱动发电机转动，以便使移动充电车在行驶的过程中也能为待充电的电动汽车或其他待充电对象进行充电，从而满足用户的特殊需求。

如图1和图2所示，本发明的移动充电车的发电系统主要包括设置在移动充电车上的发动机1、变速箱2、分动箱3、发电机4和驱动桥5。其中，发动机1的输出轴与变速箱2的输入轴驱动连接，变速箱2的输出轴与分动箱3的输入轴32(如图3所示)驱动连接，分动箱3的两个输出轴分别与发电机4和驱动桥5驱动连接。发电机4用于为待充电的电动汽车或其它的待充电对象提供充电服务，驱动桥5用于驱动移动充电车的车轮转动，进而驱动移动充电车行走。
需要说明的是，本发明所说的驱动连接指的是，相邻的两个装置或构件(例如发动机1和变速箱2)直接地或者通过其他连接机构(例如，齿轮、传动轴、传动带、链条等)间接地连接到一起，并且两个装置或构件中的一个能够驱动另一个运动。例如，发动机1的输出轴和变速箱2的输入轴通过联轴器同轴地固定连接到一起，发动机1工作时能够驱动变速箱2内的齿轮转动。
虽然图中并未示出，但是本发明的驱动桥5包括移动充电车的前桥和后桥中的至少一个。当移动充电车是前驱的车辆时，驱动桥5只包括移动充电车的前桥。当移动充电车是后驱的车辆时，驱动桥5只包括移动充电车的后桥。当移动充电车是前后共同驱动的车辆时，驱动桥5包括移动充电车的前桥和后桥。
如图1和图2所示，变速箱2通过分动箱3能够将发动机1产生的扭矩选择性地输送给发电机4或驱动桥5。
如图1所示地，当移动充电车行驶时，变速箱2通过分动箱3将发动机1产生的扭矩输送给驱动桥5。此时，发动机1驱动移动充电车行走。
如图2所示地，当移动充电车停车需要提供充电服务时，变速箱2通过分动箱3将发动机1产生的扭矩输送给发电机4。此时，发动机1驱动发电机4转动，能够为待充电的电动汽车提供充电服务。
此外，本领域技术人员也可以根据需要，使分动箱3能够将变速箱2传递的扭矩同时传递给发电机4和驱动桥5。
下面参照图3至图5来对分动箱3的主要结构和工作原理进行详细说明。
如图3所示，本发明的分动箱3主要包括箱体31、输入轴32、输入齿轮33、第一输出轴34、第一输出齿轮35、第二输出轴36、第二输出齿轮37和驱动机构38。
继续参阅图3，输入轴32、第一输出轴34和第二输出轴36分别与箱体1枢转连接。图3中输入轴32的右端与输入齿轮33同轴固定连接到一起。图3中第一输出轴34的左端与第一输出齿轮35同轴固定连接到一起。图3中第二输出轴36的左端与第二输出齿轮37同轴固定连接到一起。并且，第一输入齿轮35和第二输入齿轮37沿轴向错位设置。进一步，输入齿轮33能够沿轴向自由滑动，以便其能够选择性与第一输出齿轮35或第二输出齿轮37啮合。或者，本领域人员也可以根据需要，使输入齿轮33能够与第一输出齿轮35和第二输出齿轮37同时啮合。
需要说明的是，输入轴32与输入齿轮33之间、第一输出轴34与第一输出齿轮35之间、第二输出轴36与第二输出齿轮37之间可以采用任意可行的连接方式同轴连接到一起，例如焊接、过盈连接、螺纹连接、花键连接等。
如右图2和图3所示，图3中输入轴32的左端与变速箱2的输出轴同轴地固定连接到一起，并且输入轴32能够沿轴向滑动。具体地，变速箱2的输出轴靠近输入轴32的一端设置有外花键，输入轴32靠近变速箱2的一端设置有与所述外花键匹配的内花键。变速箱2的输出轴上的外花键插入输入轴32上的内花键中，并因此实现变速箱2的输出轴和输入轴32的同轴固定，与此同时还允许输入轴32沿轴向滑动。
继续参阅图2和图3，图3中第一输出轴34的右端与发电机4的转轴驱动连接。图3中第二输出齿轮37的右端与驱动桥5驱动连接。
需要说明的是，第一输出轴34和发电机4的转轴之间，以及第二输出齿轮37与驱动桥5之间驱动连接方式可以是，齿轮机构连接的方式、传动轴机构连接的方式、链条机构连接的方式、传动带机构连接的方式等，或者是上述多个机构相组合的连接方式。
如图3和图4所示，输入轴32上设置有相邻的第一挡块321和第二挡块322。优选地，第一挡块321和第二挡块322均是圆盘形结构，并且都与输入轴32同轴。
如图3至图5所示，驱动机构38包括固定连接到一起或一体制成的拨叉381和把手382。其中，拨叉381和把手382可以采用任意可行的方式固定连接到一起，例如焊接、螺栓连接、卡接等。
如图3和图4所示，拨叉381被设置在第一挡块321和第二挡块322之间，以便拨叉381能够通过第一挡块321和第二挡块322驱动输入轴32轴向移动。
如图5所示，拨叉381是呈U形或C形结构，并且拨叉381的内径大于输入轴32的直径，用以防止拨叉381与输入轴32接触阻碍输入轴32转动。进一步，拨叉381的外径小于第一挡块321和第二挡块322的外径，以便拨叉381能够与第一挡块321和第二挡块322相抵，进而驱动输入轴32轴向移动。
如图3所示，把手382沿输入轴32的轴向可滑动地穿过箱体31的侧壁之后，一端与拨叉381相连接或一体制成，另一端与驱动装置相连接。该驱动装置可以是电机、油缸、气缸等。该驱动装置能够驱动把手382和拨叉381沿输入轴32的轴向滑动，进而驱动输入轴32滑动。此外，本领域技术人员也可以根据需要，省去所述驱动装置，将把手382设置成能够被操作人员手动操作的形式。
下面结合图1至图3来对本发明的发电系统的工作原理进行详细说明。
如图1和图3所示，当移动充电车需要行走时，操作驱动机构38向左(图3中驱动结构的左侧)滑动，使拨叉381通过第一挡块321驱动输入轴32和输入齿轮33向左滑动，并因此使输入齿轮33和第二输出齿轮37啮合。此时，发动机1输出的扭矩通过变速箱2和分动箱3传递给驱动桥5，驱动移动充电车行走。
如图2和图3所示，当移动充电车停车并为待充电的电动汽车充电时，操作驱动机构38向右(图3中驱动结构的右侧)滑动，使拨叉381通过第二挡块322驱动输入轴32和输入齿轮33向左滑动，并因此使输入齿轮33和第一输出齿轮35啮合。此时，发动机1输出的扭矩 通过变速箱2和分动箱3传递给发电机4。发电机4发电为待充电的电动汽车进行充电。
本领域技术人员能够理解的是，发电机4的数量不仅限于图1和图2中所示的一个，其还可也是两个、三个、四个等任意多个。为了驱动多个发电机4同时工作，本领域技术技术人员可以在分动箱3上设置与发电机4数量相当的多个第一输出轴34和第一输出齿轮35。或者，本领域技术人员也可以在第一输出轴34和多个发电机4之间设置一个分动器，该分动器的输入轴与第一输出轴34驱动连接，该分动器的每一个输出轴分别连接一个发电机4。其中，分动器是现有技术中常规的分动器，且时本领域技术人员能够获得的，所以此处不再做过多说明。
基于上文的描述，本领域技术人员能够理解的是，通过在变速箱2的输出端连接一个分动箱3，并使分动箱3的第一输出轴34连接发电机4，使分动箱3的第二输出轴36连接移动充电车的驱动桥5，使得发动机1输出的扭矩能够通过分动箱3选择性地传递给发电机4或驱动桥5。因此，本发明的移动充电车与现有技术中的移动充电车相比，不再需要为发电机4配置单独的发动机，减小了移动充电车的整体重量。并且，本发明的移动充电车还可以通过变速箱2调节分动箱3的第一输出轴34输出的转速，进而调节发电机4的输出功率。进一步，本发明的分动箱3可以被设置在移动充电车的前舱内，也可以被设置在移动充电车的底盘的下侧，因此本发明的移动充电车还节约了内部空间。
此外，在输入齿轮33能够选择性地与第一输出齿轮35或第二输出齿轮37啮合的前提下，本领域技术人员也可以根据需要，使输入轴32不能轴向移动，使输入齿轮33能够相对于输入轴32轴向滑动。并且使第一挡块321和第二挡块322分别与输入齿轮33同轴固定连接。以便驱动机构38通过拨叉381能够直接驱动输入齿轮33沿轴向移动，并因此实现输入齿轮33与第一输出齿轮35或第二输出齿轮37的啮合连接。
本领域技术人员能够理解的是，在发动机1能够选择性地驱动发电机4和驱动桥5时，分动器3还可以被其他任意可行的连接装置替代。
作为示例一，所述连接装置包括第一离合器和第二离合器。与之相应地变速箱2包括第一输出轴和第二输出轴。第一离合器的主动部分与所述第一输出轴驱动连接，第一离合器的从动部分与发电机4的 转轴驱动连接。第二离合器的主动部分与所述第二输出轴驱动连接，第二离合器的从动部分与驱动桥5驱动连接。当移动充电车提供充电服务时，第一离合器的主动部分和从动部分接合，第二离合器的主动部分和从动部分分离。当移动充电车行驶时，第一离合器的主动部分和从动部分分离，第二离合器的主动部分和从动部分接合。或者，本领域技术人员也可以根据需要，使第一离合器和第二离合器的主动部分和从动部分都接合，以便使移动充电车在行驶的过程中也能够提供充电服务。其中，第一离合器和/或第二离合器优选地是电磁离合器或气动离合器。
作为示例一的替代方案，变速器2仅包括一个输出轴，变速器2和两个离合器之间设置有一个一进二出的分动器。该分动器的输入轴与变速器2的输出轴驱动连接，该分动器的两个输出轴分别驱动连接一个离合器。
作为示例二，所述连接装置包括第一连接套和第二连接套。所述第一连接套和所述第二连接套内都设置有内花键。与之相应地变速箱2包括第一输出轴和第二输出轴。所述第一输出轴和所述第二输出轴上都设置与所述内花键相匹配的外花键。发电机4的转轴上也设置有与所述内花键相匹配的外花键，驱动桥5上同样设置有与所述内花键相匹配的外花键。当移动充电车提供充电服务时，第一连接套与第一输出轴和发电机4的转轴通过花键分别同轴固定连接到一起。第二连接套与第二输出轴或驱动桥5上的外花键不能连接。当移动充电车行驶时，第一连接套与第一输出轴或发电机4的转轴不能连接。第二连接套与第二输出轴和驱动桥5上的外花键通过花键分别同轴固定连接到一起。
此外，在发动机1能够选择性地驱动发电机4和驱动桥5的情况下，本领域技术人员也可以根据需要省去变速箱2，使发动机1直接和分动箱3(或其他连接装置)驱动连接。此时，示例一中的第一输出轴和第二输出轴被设置在了发动机1上，即发动机1包括两个输出轴——第一输出轴和第二输出轴。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
