如图1-图2所示，本实施例提供了一种电动车，电动车的实施主体为两轮电动车，电动车包括车体1、散热板2和控制器3。其中，散热板2用于控制器3的安装及散热。
散热板2包括相对设置的第一面和第二面，第一面包括第一安装位21和第二安装位22，第二面上设有散热齿23，其中，第一安装位21用于固定于车体1上，第二安装位22用于安装固定控制器3。安装后的散热板2使其散热齿23至少部分外露于车体1外侧，控制器3位于车体1内侧，保证散热的同时实现控制器3防水防尘保护，从而满足通用控制器3均可通过散热板2安装固定于车体1的不同位置的安装需求，无需针对不同车型开发不同的控制器3，缩短生产周期，降低研发成本。
例如，为了提高散热齿23的散热效率，散热齿23沿车体1的长度方向延伸。在电动车行驶过程中，散热齿23迎风散热，空气沿散热齿23的一端进入，然后从散热齿23的另一端流出，保证散热齿23之间的空气流动效率，保证散热效果的同时，避免热空气烫伤驾驶人员。当然，在其他实施例中，散热齿23还可以沿车体1的宽度方向延伸。
例如，控制器3包括下壳体31、上壳体32和电路板。电路板设置在上壳体32与下壳体31形成的腔体中。为了提高控制器3的散热效果，下壳体31固定在散热板2的第二安装位22上，且第二安装位22与下壳体31之间设置有导热层。导热层可以为散热油或者矽胶布等，导热载体为聚酰亚胺或者玻纤等，既导热又绝缘。
为了便于将控制器3安装在散热板2上，同时便于将散热板2安装在第一罩壳13上，第一安装位21处与第二安装位22不重合。例如，散热板2的面积大于下壳体31的面积。
示例性地，第一安装位21上设有第一固定孔，车体1对应散热板2的位置上设有第二固定孔，通过螺丝将散热板2固定在车体1上。示例性地，所述螺丝为防盗螺丝。
为了避免水从散热板2与车体1的连接部位进入车体1内浸湿控制器3，散热板2与车体1的连接处设置有防水密封圈。
例如，车体1上用于安装散热板2的位置一侧设有导风隔热结构，便于将风导引至散热板2的散热齿23，实现对控制器3的高效散热，保证控制器3性能稳定。
例如，散热板2为铝合金板，以提高控制器3的散热效率，保证控制器3的稳定性。
例如，车体1包括踏板壳体11、座椅12和第一罩壳13，第一罩壳13位于踏板壳体11的后方及座椅12的下方。
在本实施例中，散热板2固定于第一罩壳13的侧壁上，至少部分散热齿23外露于第一罩壳13的外侧，控制器3位于第一罩壳13的内侧。
此外，将散热板2设置于第一罩壳13上侧壁上，在保证散热板2的散热效果的同时，提高安全性，避免烫伤驾驶人员。
例如，第一罩壳13上设置有导风隔热结构，导风隔热结构罩设在散热板2外侧，导风隔热结构上设置有进风口和出风口，一方面导风隔热结构能够使更多的空气进入散热齿23之间，提高散热齿23的散热效率，另一方面，导风隔热结构还能够避免散热齿23烫伤用户。
如图3-图4所示，本实施例中，散热板2的第一安装位21固定于第一罩壳13的迎风面上。
将散热板2安装在第一罩壳13的迎风面上，且控制器3位于第一罩壳13的内部，便于控制器3与驱动电机连接。
例如，第一罩壳13的迎风面上设置有导风隔热结构，导风隔热结构罩设在散热板2外侧，导风隔热结构上设置有进风口和出风口，一方面导风隔热结构能够使更多的空气进入散热齿23之间，提高散热齿23的散热效率，另一方面，导风隔热结构还能够避免散热齿23烫伤用户。
例如，第一罩壳13的迎风面上设置有导风隔热结构，导风隔热结构罩设在散热板2外侧，导风隔热结构上设置有进风口和出风口，一方面导风隔热结构能够使更多的空气进入散热齿23之间，提高散热齿23的散热效率，另一方面，导风隔热结构还能够避免散热齿23烫伤用户。
例如，散热板2与踏板壳体11呈夹角设置。示例性地，散热板2与踏板壳体11呈锐角设置，即散热板2的散热齿23向下朝向踏板壳体11的方向，以避免驾驶人员碰触到散热齿23，避免烫伤驾驶人员。在其他实施例中地，散热板2与踏板壳体11呈钝角设置，使散热齿23朝向远离踏板壳体11的方向，一方 面，保证散热齿23上的空气流动性，另一方面，避免散热齿23散发的热量烫伤驾驶人员。
在本实施例中，散热齿23可以沿车体1的宽度方向延伸。在电动车行驶过程中，散热齿23迎风散热，空气沿散热齿23之间的间隔向车体1的两侧流出，保证散热齿23的散热效果的同时，避免热空气烫伤驾驶人员。
例如，散热齿23的延伸方向与踏板壳体11的脚踏面相平行，使空气沿散热齿23之间的间隔水平向两侧流动。
如图5-图6所示，本实施例中，散热板2的第一安装位21固定于第一罩壳13的底面上。
将散热板2安装在第一罩壳13的底面上，利用散热板2上外露的散热齿23，能够提高控制器3散热效果，使控制器3性能稳定。控制器3位于第一罩壳13内部，还便于控制器3与驱动电机连接。
例如，散热板2略微后下方倾斜，散热齿23朝向迎风面，保证散热齿23上的空气流动性。
例如，散热齿23沿车体1的长度方向延伸，即散热齿23的间隔沿车体1的长度方向延伸，在电动车行驶过程中，便于空气在散热齿23之间流动，提高散热效果。在其他实施例中，散热齿23沿车体1的宽度方向延伸。在电动车行驶过程中，空气沿散热齿23之间的间隔向车体1的两侧流出，也能够提高散热齿23的散热效果。
如图7所示，本实施例中，散热板2的第一安装位21固定于踏板壳体11的脚踏面上。
踏板上设置有导风隔热结构，导风隔热结构罩设在散热板2外侧，导风隔热结构上设置有进风口和出风口，一方面导风隔热结构能够使更多的空气进入散热齿23之间，提高散热齿23的散热效率，另一方面，导风隔热结构还能够避免散热齿23烫伤用户。
如图8所示，本实施例中，散热板2的第一安装位21固定于踏板壳体11的底面上。
在本实施例中，散热齿23沿车体1的长度方向延伸。在电动车行驶过程中，散热齿23迎风散热，空气沿散热齿23的一端进入，然后从散热齿23的另一端流出，保证散热齿23之间的空气流动效率，保证散热效果的同时，避免热空气 烫伤驾驶人员。例如，散热齿23还可以沿车体1的宽度方向延伸，也能够提高散热板2的散热效果。
如图9-图12所示，本实施例中，电动车的实施主体为三轮电动车。车体1包括车斗14、座椅12和第二罩壳15。
在本实施例中，所述电动车中的控制器3可采用通用控制器3，无需单独开发不同型号的控制器3，生产周期短，成本低；此外，将控制器3安装在散热板2上，利用散热板2上外露的散热齿23，能够提高控制器3散热效果，使控制器3性能稳定。
如图10-图11所示，将散热板2安装在第二罩壳15的底面上，且控制器3位于第二罩壳15的内侧，即控制器3位于车斗14和第二罩壳15之间，提高了控制器3的安装可靠性。
散热齿23沿车体1的长度方向延伸，即散热齿23的间隔沿车体1的长度方向延伸。当电动车行驶时，电动车的行驶方向与散热齿23的延伸方向相同，进而气流的方向与散热齿23的延伸方向相同，提高了散热效果。于其它实施例中，散热齿23沿车体1的宽度方向延伸，当电动车行驶时，空气沿散热齿23之间的间隔向车体1的两侧流出，也能够提高散热齿23的散热效果。
控制器3包括下壳体31、上壳体32和电路板。电路板设置在上壳体32与下壳体31形成的腔体中。
如图12所示，散热板2的第一面的面积大于控制器3下壳体31的面积，以便于控制器3安装于散热板2上，同时散热板2能够安装于第二罩壳15上。
