The utility model discloses an end cover of an electric wheel hub motor and a wheel hub motor containing the end cover, belonging to the technical field of electric vehicles. The utility model provides an end cover of an electric wheel hub motor, which is characterized in that a number of grooves are arranged on the ring mounting plane inside the end cover to prevent the sealant from overflowing the outer edge of the end cover, and the grooves are circumferentially distributed. At the same time, an electric wheel hub motor including the rim, the magnetic conducting ring and the end cover is provided. The magnetic conducting ring is circular and welded to the rim inner ring. The groove on the end cover forms a closed inner cavity with the end face of the magnetic conducting ring. The utility model has the beneficial effect that the overflow sealant is collected through the groove, which is beneficial to the glue dispersing, reduces the thickness of the glue layer, reduces the axial movement, improves the efficiency and torque, and ensures that the outer surface of the motor is clean and glueless. In addition, the water-proof effect is improved by the gel in the groove, and the dosage of the end cover material is reduced. The cost is saved.

一种电动车轮毂电机的端盖及含有该端盖的电机
本技术涉及电动车
,特别是涉及一种电动车轮毂电机的端盖及含有该端盖的电机。
技术介绍
现代社会,环保观念深入人心,电动车作为代步工具已融入人们的日常生活,随着生活水平的提高,消费者在对消费产品的性能优越的基础上,对产品外观和电机舒适性要求也越来越苛刻。电动车电机的核心驱动装置是轮毂电机,因而电动车电机的外观和性能显得日益重要。现有技术中,应用于电动车上的轮毂电机,其端盖安装时,为保证防水密封性,在安装平面上涂覆密封胶,而一般电机的安装平面为一连续光整的单一圆环平面,密封胶在受挤时会往外圈溢散,这就会导致密封胶会流溢至电机的外表面上,影响电机外观的整洁性,也给电机的外观清理工作带来麻烦,且密封胶为保证其防水能力,需具备一定的流动性和粘稠度,而这会导致密封胶层不易挤出且过厚的密封胶凝结层会增加电机的轴向间隙,造成电机轴向窜动引起振动,电机定、转子轴向错位,会使电机的效率和扭矩降低,为解决上述问题,同时实现降本增效是本技术的创研动机。
