Problems solved by technology

The electric balance car needs a controller to control the start, running speed, and direction of the balance car, but the controllers of most existing two-wheel electric balance cars are all located in the balance car shell, which makes the installation steps of the balance car cumbersome and impossible. To achieve modular and quick installation, the production cost of the balance car is relatively high

Embodiment 1

[0086] as attached figure 1 As shown, in this embodiment, the controller is a circuit board structure, including the control circuit board 21 and the components on it, the installation part includes the flat mouth structure 211 and the fixing part 25 in the middle of the control circuit board 21, and the through hole of the motor shaft 11 There is a step 112 on the exit end 111, and the shape of the flat mouth structure 211 is adapted to the shape of the exit end 111. Position against the step 112 under the action. In a specific embodiment, there is a certain distance between the step 112 and the inner end cover 15, so that the controller is kept at a certain distance from the rotating inner end cover 15 to protect the controller.

[0087] Preferably, the fixing member 25 can be a circlip, and correspondingly, a positioning groove for fixing the circlip is provided on the exit end 111 of the motor shaft 11; or, the fixing member 25 can be a nut, and the exit end 111 of the mo...

Embodiment 2

[0094] Based on the above-mentioned embodiment, the difference between this embodiment and Embodiment 1 is that the installation part includes a fixed seat, and the controller is a control circuit board structure, including a control circuit board and components on it. The exit end is fixedly connected, and other structures are the same as those in Embodiment 1.

[0095] as attached Figure 4 And attached Figure 5 As shown, the fixed seat 23 of the present embodiment is elongated, and the fixed seat 23 is elongated, and the center is provided with a flat mouth structure, which is used for the fixed connection of the passing end 111 of the motor shaft 11. The fixed seat 23 is provided with a The first flat groove 231 fitted with the motor shaft 11 makes the fixing seat 23 and the motor shaft 11 relatively stationary; the edge of the first flat groove 231 is provided with a first protrusion 232, and the first protrusion 232 protrudes toward the inner end cover Setting, the fi...

Embodiment 3

[0098] as attached Image 6 And attached Figure 7 As shown, in this embodiment, the controller is a circuit board structure, including a control circuit board 21 and components on it, and the installation part includes a fixing seat 23, the controller is fixedly connected to the fixing seat 23, and the fixing seat 23 is connected to the motor shaft 11 The piercing end 111 is fixedly connected. as attached Image 6 As shown, the controller is fixed on the fixed seat 23, and the fixed seat 23 is fixedly connected with the passing end 111 of the motor shaft 11. The advantage of this embodiment is that it avoids excessive processing of the control circuit board 21 of the controller, and the fixed seat 23 It can be processed by injection molding to reduce costs. Preferably, the fixing seat 23 can be made of heat insulating material, so as to prevent the motor shaft 11 from conducting the heat of the hub motor to the controller.

Abstract

The invention discloses a balance car wheel and a balance car thereof. The balance car wheel comprises a hub motor and a balance car controller assembly, the hub motor comprises a motor shaft and a hub, and the motor shaft transversely penetrates through the hub and penetrates out of one side of an inner end cover of the hub; the controller assembly comprises a controller and a mounting part, and the controller is fixed to the penetrating-out end of the motor shaft through the mounting part and arranged close to the inner end cover of the hub, wherein the motor shaft comprises a connecting part fixedly connected with the vehicle body, and the controller assembly located at the penetrating-out end of the motor shaft is at least partially arranged in the vehicle body. The balance car wheel has the advantages that the controller is taken out of the balance car body, the car body structure of the balance car is reduced, the balance car is more compact, and the controller and the wheels of the balance car are modularized; the problem that an existing balance car is tedious in installation step is solved. The controller module is partially arranged in the car body and partially arranged outside the car body, so that the length of a motor shaft and the overall width of the balance car can be shortened.

Description

technical field [0001] The invention relates to the technical field of balance vehicles, in particular to a balance vehicle wheel and the balance vehicle. Background technique [0002] Two-wheeled self-balancing vehicles have developed rapidly in recent years, including the early purely mechanical self-balancing vehicles and the later developed electric self-balancing vehicles, which can be used for both sports competitions and leisure and entertainment, and are deeply loved by people from all over the world. . The electric balance car needs a controller to control the start, running speed, and direction of the balance car, but the controllers of most existing two-wheel electric balance cars are all located in the balance car shell, which makes the installation steps of the balance car cumbersome and impossible. To realize modularized quick installation, the production cost of the balance car is relatively high. Contents of the invention [0003] In order to overcome the...
