Problems solved by technology

[0006] However, since the hub motor is rotating, especially the hub left cover and the hub right cover of the hub motor are rotating, the wheel cover of the electric vehicle and the components such as the battery and the driver installed inside the wheel cover need to avoid the rotating hub motor. Therefore, a certain distance should be kept between the inner wall of the wheel cover of the electric vehicle and the left cover and the right cover of the hub motor. In this way, the overall thickness of the electric vehicle is thicker and the volume is larger. On the other hand, the hub motor and the The weight of the entire electric vehicle is also relatively heavy. These factors have caused electric vehicles, especially electric unicycles, to be inconvenient to carry.

Embodiment 1

[0038] Such as Figure 1 to Figure 6 As shown, the electric unicycle in this embodiment mainly includes a wheel cover 1 and a hub motor 2 assembled in the wheel cover 1. The wheel cover 1 at least partially covers both sides of the hub motor 2, exposing the tires located below the hub motor 2. for driving electric vehicles. The wheel cover 1 includes a first wheel cover 11 and a second wheel cover 12 respectively located on two sides of the hub motor 2 .

[0039] The hub motor 2 includes a hub 21 , a hub 22 , a rotor 23 and a stator 24 . Tires 220 are provided on the hub 22 . The stator 24 is fixedly installed on the wheel cover 1 , the rotor 23 is fixed on the wheel hub, and the wheel hub 22 is rotatably installed on the wheel cover through the wheel shaft 21 . Thus, after the electric unicycle is powered on, the wheel hub 22 can be driven to rotate relative to the wheel cover 1 .

[0040] In this embodiment, the stator 24 is fixedly installed on the inner wall surface of...

Embodiment 2

[0058] The difference between the electric vehicle of Embodiment 2 and Embodiment 1 mainly lies in that the structure of the in-wheel motor is different.

[0059] Specifically, see Figures 7 to 9 , the in-wheel motor of embodiment 2, which is arranged between the first wheel cover 11' and the second wheel cover 12', which includes a wheel shaft 21', a hub 22', a rotor 23' and a stator 24'.

[0060] Wherein, the stator 24' includes a first stator 24a' detachably mounted on the first wheel cover 11' and a second stator 24b' mounted on the second wheel cover 12'.

[0061] Mounting portions for mounting the first stator 24a' and the second stator 24b' are respectively provided on the first wheel house cover 11' and the second wheel house cover 12'. The structure of the installation part is the same as that in Embodiment 1, so it will not be repeated here.

[0062] A first rotor 23a' cooperating with the first stator 24a' and a second rotor 23b' cooperating with the second stato...

Embodiment 3

[0068] The difference between the electric vehicle of Embodiment 3 and Embodiment 2 is that the hub 22" is pivotally connected to the wheel shaft 21", and the wheel cover 1" is relatively fixedly connected to the wheel shaft 21".

[0069] Such as Figure 10 As shown, the hub 22" is pivotally connected with the axle 21" through the bearing 211".

[0070] Blind holes 122" fixedly fitted with the wheel cover 21" are respectively provided on the inner walls of both sides of the wheel cover 1".

Abstract

The invention relates to an electric vehicle. Compared with the scheme of assembling the finished hub motor with the electric wheel cover in the prior art, the present invention creatively disassembles the finished structure of the original hub motor, and installs the stator of the hub motor on the inner wall of the electric wheel cover; The hub cover of the wheel hub motor is directly replaced by the wheel cover cover of the wheel cover of the electric vehicle, which simplifies the overall structure of the hub motor and the electric vehicle, reduces the weight, and can reduce the gap between the wheel cover and the hub motor. The overall thickness of the electric vehicle is reduced, especially the thickness of the electric unicycle can be reduced, making it easy to carry.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to an electric vehicle with an improved wheel hub motor structure. Background technique [0002] The in-wheel motor, also known as the built-in motor in the wheel, integrates the power device, transmission and braking devices into the wheel hub, so that the mechanical part of the electric vehicle can be greatly simplified. [0003] Generally, an in-wheel motor at least includes a wheel shaft, a hub pivotally connected to the wheel shaft, a rotor mounted on the hub and rotating together with the hub, a stator corresponding to the rotor, and a hub shell. The hub shell includes a hub left cover arranged on the left side of the hub and a hub right cover arranged on the right side of the hub, which together seal the central part of the hub and components such as the rotor and stator, so as to be waterproof and dustproof. [0004] When the hub motor is installed in an electric vehicle, especially i...
