Embodiment 1

[0023] see figure 1 and figure 2 As shown, the electric balance vehicle of the present invention includes a wheel 1, a housing 2 covering the wheel, two pedals 3 located on both sides of the wheel 1, a power supply 4 and a control system installed in the housing.

[0024] Please reunite image 3 and Figure 4 As shown, the wheel 1 includes a rim 11 , a motor assembly and two fixing parts 12 . Certainly, the two fixing parts 12 may not be parts of the wheel, but may only be regarded as connecting elements between the pedal 3 and the wheel. In this embodiment, it is still considered that the wheel includes a fixing part for description. The motor assembly includes a stator 13 , a rotor 14 disposed on the outer periphery of the stator 13 , two bearings 15 , and two connecting pieces 16 . The stator 13 includes an inner ring body 131 and a winding body 132 disposed on the outer periphery of the inner ring body 131 . The inner ring body 131 encloses a cavity 130 . The windin...

Embodiment 2

[0030] see Figure 5 As shown, it shows the second embodiment of the electric balance car of the present invention. The difference from the first embodiment is that the rim 11 of the wheel 1 is a single rim wheel.

Abstract

The invention discloses a wheel, which includes a rim and a motor assembly, the motor assembly includes a stator, a rotor, two bearings and two connectors, the stator includes an inner ring body and a winding body arranged on the inner ring body, the The width of the inner ring body in the axial direction of the stator is greater than the width of the winding body in the axial direction of the stator, the inner rings of the two bearings are respectively placed on the inner ring body of the stator, and the two bearings are respectively located on both sides of the winding body, The rim is fixedly arranged on the rotor, and the two connecting pieces respectively connect the outer rings of the two bearings and the rotor or the rim, and the inner ring body forms a cavity, at least part of which penetrates through the axial direction of the stator wheel. The inner ring body of the stator surrounds a cavity, and at least part of the cavity penetrates the wheel, so the penetrating part of the wheel has no structural components, thereby reducing the weight of the wheel and increasing portability.

Description

technical field [0001] The invention relates to a wheel and a motor assembly of a walking tool, in particular to a wheel and a motor assembly of an electric balance car. Background technique [0002] With the development of the economy, many social problems such as energy shortage, increasingly serious automobile emission pollution, and common traffic jams in cities are becoming increasingly apparent. In recent years, electric vehicles, as a new generation of means of transportation, have become more and more popular among consumers. The most common electric vehicles in daily life are two-wheeled electric vehicles, whose two wheels are arranged front and back, similar to bicycles. This common electric vehicle is generally bulky, and portability needs to be improved. [0003] With the rapid development of society, people's pursuit of a better life has not changed, and the research and development and design of transportation tools are increasingly pursuing novelty and indivi...
