具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本申请进行进一步详细说明。应当理解,此处所描述的具体实施例仅用以解释本申请,并不用于限定本申请。
需说明的是,当部件被称为“固定于”或“设置于”另一个部件,它可以直接在另一个部件上或者间接在该另一个部件上。当一个部件被称为是“连接于”另一个部件,它可以是直接或者间接连接至该另一个部件上。术语“上”、“下”、“左”、“右”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本申请的限制,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的具体含义。术语“第一”、“第二”仅用于便于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明技术特征的数量。“多个”的含义是两个或两个以上,除非另有明确具体的限定。
电动汽车的车体通常设有机舱,机舱主要用于容置电驱动装置、转向机、热管理装置等机构,其中,电驱动装置包括电机和减速器,电机用于将电动汽车的电池所提供的电能转化为驱动力,减速器用于以降低转速、增大扭矩的方式将该驱动力输出至电动汽车的车轮上,以驱动电动汽车移动。由于电驱动装置的体积较大,而且机舱的内部空间较小,为了避免电驱动装置与机舱内的其它机构出现相互干涉的情况,对电驱动装置在机舱内的布置方式进行优化显得尤为重要。
本申请的发明人注意到,目前电动汽车的电驱动装置的布置方式一般分为纵向布置方式和水平布置方式,其中,纵向布置方式是指电机的动力输出轴的轴线与减速器的动力输入轴的轴线所限定出的布置平面大致垂直于电动汽车的支撑平面,水平布置方式是指电机的动力输出轴的轴线与减速器的动力输入轴的轴线所限定出的布置平面大致平行于电动汽车的支撑平面。然而,纵向布置方式会使得电驱动装置过多地占用机舱的纵向空间,而水平布置方式会使得 电驱动装置过多地占用机舱的水平空间,而且还需要让电驱动装置对机舱内的其它机构进行避让,因此,不管采用纵向布置方式还是采用水平布置方式将电驱动装置布置在机舱内,都会导致各个机构在机舱内的布局结构的紧凑度下降,从而导致机舱的空间利用率降低。
为了提高机舱的空间利用率,本申请的发明人经过深入研究,设计了一种电驱动装置,该电驱动装置将由动力输出轴的轴线与动力输入轴的轴线共同限定出的布置平面与车辆的支撑平面相对倾斜设置,如此,电驱动装置能够采用倾斜方式布置在车辆的机舱内,以对安装于机舱内的其它机构进行避让,使得电驱动装置能够充分利用机舱的内部空间,从而使得各个机构在机舱内部的布局结构变得更加紧凑,有效提高了机舱的空间利用率。
本申请实施例公开的电驱动装置可以用于将电能转化为驱动力并由该驱动力驱动其运动的各种移动设备。移动设备包括但仅不限于电动玩具、电动工具、车辆、轮船、航天器等等。

具体地,盖体131与电机11的外侧和/或减速器12的外侧相配合以使安装腔1311与电驱动装置10的外部环境相分隔,具体地,安装腔1311具有腔 口,控制组件132可以经由腔口安装至安装腔1311内,腔口的边缘与电机11的外侧和/或减速器12的外侧相连接,以使安装腔1311与电驱动装置10的外部环境相分隔,从而提供用于容纳控制组件132的内部环境。盖体131的安装方式包含多种,例如,盖体131可以通过诸如螺栓、螺钉等紧固件安装在电机11的外侧和/或减速器12的外侧;又如,盖体131可以焊接于电机11的外侧和/或减速器12的外侧;在此不作具体限定。

在相关技术中,控制器13的安装方式通常是先在电驱动装置10的内部设置基板,再将控制组件132的各个模块逐一安装在基板上,由于电驱动装置10的内部空间较小,因此导致控制组件132的安装难度增大,而且需要额外设置基板,导致电驱动装置10的结构紧凑度降低。
通过采用上述技术方案,在将控制组件132安装于盖体131的安装腔1311内后,可将控制组件132和盖体131作为一个整体安装在电机11的外侧和/或减速器12的外侧上,而无需在狭窄的电驱动装置10的内部空间内对控制组件132进行装配操作,从而有效降低了控制器13的装配难度,也无需在电驱动装置10的内部设置用于安装控制组件132的基板,从而有效提高了电驱动装 置10的结构紧凑度。
在本申请的一些实施例中,请参阅图5,控制器13还包括安装座133,盖体131安装于安装座133,电机11包括第一壳体112,减速器12包括第二壳体122,第一壳体112、第二壳体122和安装座133一体成型。

通过采用上述技术方案,有效减少了第一壳体112、第二壳体122和安装座133之间的连接部件,从而进一步提高了电驱动装置10的结构紧凑度。
在本申请的一些实施例中,安装腔1311与第一壳体112的内腔相连通。
通过采用上述技术方案,在将控制组件132与电机11进行电连接操作时,可在电驱动装置10的内部进行走线,从而进一步提高了电驱动装置10的结构紧凑度。
在本申请的一些实施例中,请一并参阅图3及图4,电驱动装置10还包括控制器13,控制器13与电机11电连接,控制器13安装于电机11与减速 器12之间的连接处的外侧,控制器13的安装平面与布置平面14相平行。
当电机11的第一壳体112与减速器12的第二壳体122一体成型时,电机11与减速器12之间的连接处即为第一壳体112与第二壳体122之间的连接处。当布置平面14自动力输入轴121的轴线朝车辆1000的前上侧方向倾斜设置时(如图4所示),电机11与减速器12之间的连接处的外侧可以为该连接处的后上侧(如图4中的右上角位置,也就是图4中控制器13所在的位置),也可以为该连接处的前下侧(如图4中左下角位置);当布置平面14自动力输入轴121的轴线朝车辆1000的后上侧方向倾斜设置时,电机11与减速器12之间的连接处的外侧可以为该连接处的前上侧,也可以为该连接处的后下侧。
控制器13的安装平面是指控制器13在完成安装操作后所处的平面,例如,当控制器13包括盖体131和安装座133且安装座133、第一壳体112和第二壳体122为一体成型时,安装座133与第一壳体112和/或第二壳体122之间的交接面即为控制器13的安装平面。
当然,在实际应用中,由于存在制造误差,控制器13的安装平面也可以相对于布置平面14略微倾斜。
通过采用上述技术方案,使得控制器13能够充分利用电机11与减速器12之间的连接处的外侧空间,从而有效提高了电驱动装置10的结构紧凑度。
在本申请的一些实施例中,请一并参阅图3、图5、图6及图7,控制器13包括盖体131和控制组件132,控制组件132与电机11电连接,盖体131具有安装腔1311,控制组件132安装于安装腔1311内,盖体131安装于电机11与减速器12之间的连接处的外侧。
通过采用上述技术方案,在将控制组件132安装于盖体131的安装腔1311内后,可将控制组件132和盖体131作为一个整体安装在电机11与减速器12 之间的连接处的外侧,而无需在狭窄的电驱动装置10的内部空间内对控制组件132进行装配操作,从而降低了控制器13的装配难度,也无需在电驱动装置10的内部设置用于安装控制组件132的基板,从而进一步提高了电驱动装置10的结构紧凑度。
在本申请的一些实施例中,请一并参阅图2及图7,盖体131位于电机11的靠近车辆1000的驾驶舱320的一侧,盖体131的靠近车辆1000的驾驶舱320的一侧设有避让部1312。
由于控制器13的安装平面平行于布置平面14,且盖体131位于电机11的靠近车辆1000的驾驶舱320的一侧,换言之,控制器13大致位于电机11与减速器12之间的连接处的后上侧。
避让部1312是指盖体131用于避让外部部件的部位,避让部1312的形式包含多种,例如,避让部1312可以为盖体131的切角部位,即将盖体131的靠近车辆1000的驾驶舱320的角部设置成切面,该切面与车辆1000的机舱310和驾驶舱320之间的分隔结构350大致平行。
由于本申请实施例提供的电驱动装置10是通过在盖体131内设置安装腔1311并且将控制组件132安装在安装腔1311内,这样会导致盖体131的凸出高度较大,使得盖体131容易与车辆1000的机舱310和驾驶舱320之间的分隔结构350产生干涉,当车辆1000发生碰撞时,盖体131容易与该分隔结构350相互碰撞。
通过在盖体131的靠近车辆1000的驾驶舱320的一侧设有避让部1312,有效增加车辆1000的机舱310和驾驶舱320之间的分隔结构350与盖体131的距离,从而有效降低盖体131在车辆1000发生碰撞时与该分隔结构350相互碰撞的风险。
在本申请的一些实施例中,请参阅图3,电驱动装置10还包括控制器13,控制器13包括与电机11电连接的控制组件132,控制组件132包括功率模块,功率模块为碳化硅功率模块。

通过采用上述技术方案,有效提高了电驱动装置10的功率密度,从而使得电驱动装置10的结构变得更加紧凑。
当然,在其它实施例中,功率模块也可为MOSFET功率模块、IGBT功率模块等,在此不作具体限定。

通过采用上述技术方案,无需在电驱动装置10上额外设置动力泵和管路来向冷却套113输送冷却介质,不仅降低了电驱动装置10的制造成本,而且有效提高了电驱动装置10的结构紧凑度。
在本申请的一些实施例中,请一并参阅图5及图8,减速器12包括第二壳体122和安装于第二壳体122内的齿轮组123,第二壳体122具有用于储存油液的储油腔1221,齿轮组123与油液相接触。
齿轮组123包括多个齿轮,相邻两个齿轮相互啮合,各个齿轮之间的齿比可以根据实际应用需要进行设定,齿轮组123的任一个或者多个齿轮与储油腔1221的油液相接触,当齿轮组123运转时,油液可以在离心力的作用下在减速器12的内部飞溅,从而达到对减速器12的内部部件进行润滑的目的。
储油腔1221设置于第二壳体122的内腔底部,储油腔1221中的油液的液面至少浸润齿轮组123的最低部位,以保证齿轮组123能够与油液有效接触。减速器12还可以包括液位检测单元,液位检测单元设置于储油腔1221内,液位检测单元用于对储油腔1221内的油液的液面高度进行实时检测,以防止储油腔1221内的油液的液面的高度小于齿轮组123的最低部位的高度而导致减速器12的内部润滑失效。
通过采用上述技术方案,无需在电驱动装置10上额外设置动力泵和管路来向减速器12内部输送润滑油,不仅降低了电驱动装置10的制造成本,而且有效提高了电驱动装置10的结构紧凑度。
在本申请的一些实施例中,请参阅图2,布置平面14与支撑平面200所 成夹角α的角度为32°-82°。
夹角α的角度可以根据实际应用需要而定,具体可为32°、57°、82°等,在此不作具体限定。
通过采用上述技术方案,使得电驱动装置10对机舱310的宽度空间和高度空间的占用量限制在合理范围内,使得电驱动装置10能够更加充分地利用机舱310的内部空间,从而使得机舱310内部的布局结构变得更加紧凑,进一步提高了机舱310的空间利用率。

当然,在其它实施例中,电池20的输出电压也可为400V。
