The unilateral hub motor comprises a motor body and a connecting arm, the connecting arm comprises an arm body and an arm head installed at the top of the arm body, a controller is installed in the connecting arm, a groove is formed in the side, close to the motor body, of the connecting arm, and a reinforcing plate is arranged in the groove in the length direction of the groove. A plurality of rows of flow guide reinforcing plates arranged in the width direction of the reinforcing plate are arranged on one side of the reinforcing plate, penetrating holes penetrating through the reinforcing plate are formed in the portion, between every two adjacent flow guide reinforcing plates, of the reinforcing plate, the penetrating holes are communicated with a flow guide channel, the connecting arm comprises a front side blocking edge and a rear side blocking edge, and the front side blocking edge and the rear side blocking edge are located on the two sides of the connecting arm respectively. A through strip-shaped side hole is formed in the front side blocking edge and communicated with the flow guide channel. Airflow formed through relative movement with the wheel penetrates through the side holes and moves to the whole groove through the flow guide channels and the penetrating holes formed between the two adjacent flow guide reinforcing plates, and heat of the connecting arm can be taken away easily.
本发明公开了一种单边轮毂电机,包括:电机主体和连接臂,所述连接臂包括臂体和安装在臂体顶部的臂头,所述连接臂中装有控制器,所述连接臂靠近电机主体一侧装有凹槽,所述凹槽中沿着其长度方向设有加强板,所述加强板一侧设有多排沿其宽度方向布置的导流加强板,位于相邻的两块导流加强板之间的加强板上设有贯穿加强板的穿孔,穿孔连通导流通道,所述连接臂包括前侧挡缘和后侧挡缘,所述前侧挡缘和后侧挡缘分别位于连接臂的两侧,所述前侧挡缘上设有贯通的条状的侧孔,所述侧孔连通导流通道。本发明通过与车轮的相对运动而形成的气流穿过侧孔,并经由邻的两块导流加强板之间形成导流通道和穿孔运动至整个凹槽处,其有利于将连接臂热量带走。
