Title of Invention : An Intelligent Balance Vehicle

Field of the Invention

[0001]
The present invention relates to an intelligent balance vehicle, especially relates to an electronic balance vehicle which can be driven by self-balance of a driver or reversing a loading platform by feet of drivers.
[0002]
Background of the Disclosure
[0003]
The electronic balance vehicle is a new transport tool leading a great fashion in recent years, main working principle of which is established on a basic principle called “Dynamic Stabilization” , namely the auto balance capability of the vehicle. After sensing the pivot status of the balance vehicle, a central microprocessor is used to compute and analyze in order to control the motor to act correspondingly, realizing the dynamic stabilization of the balance vehicle.
[0004]
From the appearance, a normal electronic balance vehicle is general composed of two wheels which are separately distributed at the right and left sides of the driver; the middle of the two wheels is equipped with two loading platforms capable of relatively rotating; the driver stands with two feet separately on the two loading platforms, pivoting the loading platforms standing on by change of feet or driver’s weight in order to control the balance vehicle to move forwards or backwards, stop, rotate, etc.
[0005]
However, the existing electronic balance vehicle generally fixes a rotating mechanism (including two bearings and one axle sleeve) in the cylinder on the opposite inner sides of two loading platforms, and positions two wheels ratatably on the opposite outer sides of two loading platforms. Although such a structure can realize free pivoting between the two loading platforms and the two wheels, two ends of each loading platform (which are the joint between each loading platform and the rotating mechanism and the wheel) become the major stress concentration points which are generally the easiest damaged parts of the electronic balance vehicle.
[0006]
To overcome such defects, some existing electronic balance vehicles increase the thickness of the loading platform and add enhancement elements on each joint to maintain the strength of the entire structure. However, such a method will increase the weight of the electronic balance vehicle and is inconvenient for assembly.
[0007]
In conclusion, the existing electronic balance vehicle still needs to be improved.

Two end of the axis 10 are equipped with two vehicle components with central symmetry of the axis 10, each vehicle component is equipped with a wheel and a pedal unit 60 and the axis 10 is connected to the wheel across the vehicle component. The wheels are rotatably positioned at the ends of the axis 10, the vehicle components are positioned rotatably at the outsides of the axis 10, and the inside of the pedal unit 60 is equipped with a driving unit 40 and a control unit 50.
[0035]
Figure 3, Figure 4 and Figure 5 illustrate that the intelligent balance vehicle 1 in the example adopts a two-wheel structure, in which the wheels include the a wheel 20 and a second wheel 30, and the first wheel 20 and the second wheel 30 are separately and rotatably positioned at two ends of the axis 10.
[0036]
Correspondingly, the pedal unit 60 includes a first pedal 62 and a second pedal 64, and the first pedal 62 and the second pedal 64 can be separately positioned between the first wheel 20 and the second wheel 30 or at the outsides of the first wheel 20 and the second wheel 30; meanwhile, the driving unit 40 includes a first driving module 42 and a second driving module 44.
[0037]
Figure 6 illustrates that the inside of the first pedal 62 is equipped with the first driving module 42 and the control unit 50, and the first driving module 42 includes a first driving source 424, a first gear set 426 and a first body 422 jointed on the axis 10; meanwhile, the first driving source 424 and the first gear set 426 are separately fixed on the first body 422 so that the first driving source 424 can drive the rotation of the first wheel 20 by the first gear set 426.
[0038]
Similarly, the inside of the second pedal 64 is equipped with the second driving module 44 and the control unit 50, and the second driving module 44 includes a second driving source 444, a second gear set 446 and a second body 442 jointed on the axis 10; meanwhile, the second driving source 444 and the second gear set 446 are separately fixed on the second body 442 so that the second driving source 444 can drive the rotation of the second wheel 30 by the second gear set 446.
[0039]

By reference to Figures 3 to 6, since the first wheel 20, the first driving module 42 and the second driving module 44 of the driving unit 40 and the second wheel 30 are jointed on the axis 10 in due order, the stress of the intelligent balance vehicle in use can be effectively and evenly dispersed to the axis 10. Thus, the defects of the existing balance vehicles that the stress are concentrated on a few stress concentration points can be effectively improved to reduce the risk of damage and improve the entire durability.
[0044]
The existing electronic balance vehicle usually maintains the strength of the entire structure by means of increasing the thickness of the loading platform and adding enhancement elements on each joint. However, the intelligent balance vehicle 1 of the invention can disperse the stress evenly to the axis 10, so that adding medal material or enhancement element is not needed, thus reducing the entire weight of the balance vehicle, saving the cost of materials and improving the convenience of assembly.
[0045]
The above is just some preferable examples of the invention with no limitation to the invention. Any changes, modifications, equivalent substitutions, improvements and the like made without departing from the spirit and the scope of the invention shall be included within the protection scope the invention.
