The rim ίο is covered with a - star rim cover 12, the rim cover 12 is oppositely closed with the plurality of connecting members 11 to close the recess 114, and the power supply battery 40 and the casing 41 are positioned inside the recess 114. A second fixing portion 12 is disposed in the center of the ring cover 12 for fixing the second fixing portion (10) to the second fixing hole (121), and the second through hole 121 is for the central axis to pass through. As shown in FIGS. 3 and 6, In the embodiment, the box body 41 has an integral star shape, and a circular hole 42 is formed in the center thereof. The circular hole 42 is for the housing 31 to pass through, and the box body 41 accommodates a plurality of power supply batteries 40, and the branches of the star box body 41 are along the branches. The connecting member 丨丨 extends and is fixed to arrange a plurality of power supply batteries in the radial direction of the rim 10. VI. Therefore, by the above structural design, it can be concluded that the present invention has the following advantages: 1. The overall structure of the hub motor is simplified, so it can be effectively applied to electric wheels. 2. The central shaft assembly of the hub motor includes a coaxial first fixed shaft, a second fixed shaft and a rotating shaft. The unidirectional bearing is arranged between the planetary carrier and the second fixed shaft, and the integral member is simplified and systematic, and is easy to assemble. Furthermore, the second fixed shaft and the rotating shaft are connected by a fifth bearing to make the mechanism more stable. ^ 201236918 3, The electric wheel itself is equipped with a power supply to form a complete integrated structure for easy use of women's clothing on various electric vehicles and to avoid the inconvenience of arranging power wires and controlling wires on the frame. Sex and affect the beauty of the car body. 4, the power supply battery g] is set in the rim of the connector ±, located in the periphery of the pure motor, and the connection between the power supply battery and the shaft touch is directly transferred from the housing by the towel ^, the central shaft does not need to drill Holes, thus improving structural strength and safety. 5. There are a plurality of power supply batteries and a box body, the box body is star-shaped, and each branch content is provided with a plurality of power supply electric star box bodies, each branch is fixed on the connecting member and extends along the radial direction of the rim, so that the star Each branch of the box contains a plurality of power supply batteries and is arranged in the radial direction of the rim, so that a sufficient power source can be supplied. The female connector is in the shape of a plate and has a recess for the box body to accommodate the power supply battery, and the sling-star rim cover is used to seal each (10) and to be set, so that the assembly can be simplified. . The above description is only for the purpose of the present invention, and is not intended to limit the scope of the invention, which is within the scope of the invention as set forth in the following claims. This is the patent requirement, and the application for the law is filed in accordance with the law. I would like to ask the bureau to make a profit in accordance with the law.
