Description

Electric balance car [Technical Field]

The present invention relates to a walking tool, and more particularly to an electric balancing vehicle.

【Background technique】

With the advancement and development of science and technology, the similarities of the means of transportation have become more diverse. In recent years, electric scooters have emerged on the market as a small means of transport;

Existing electric balance vehicles generally have an operating lever, and the user operates on the pedal platform of the balance vehicle to operate the lever to advance, retreat, and stop. Such control is also referred to as "hand control." At present, the balance car is generally a plate-shaped flat plate, which is always in a horizontal state during use and cannot be relatively rotated, so the user cannot operate the balance car by simply using the foot.

It should be noted that the above description of the technical background is only for the purpose of facilitating a clear and complete description of the technical solutions of the present application, and is convenient for understanding by those skilled in the art. The above technical solutions are not considered to be well known to those skilled in the art simply because these aspects are set forth in the background section of this application.

The electric balance vehicle further includes a left pedal and a right pedal, and the left pedal and the right pedal are respectively rotatably disposed on the support shaft;

a hub motor for driving two left and right wheels to rotate;

A balance control system is coupled to the hub motor and is configured to control the hub motor to drive the left and right wheels to rotate.

The invention has the beneficial effects that the present invention provides a support shaft and a left pedal and a right pedal that can rotate around the support shaft, so that the left pedal and the right pedal can be relatively rotated, and the balance control system and other components are used. One or two of the left or right pedals can be controlled to rotate at a certain angle by the movement of the foot, so that the user can perform acceleration, deceleration and steering operations on the balance vehicle only through the foot movement. The user is provided with a drive control method different from the "foot control"; and, because the structure of the operating lever is reduced, the weight of the balance car is reduced, and the user is more convenient to use, for example, when getting on and off the vehicle, In addition, since the support shaft penetrates the left pedal and the right pedal in the present invention, when the pedal is pressed, the support shaft will play a considerable supporting role, and the support structure is connected to a certain extent. In general, in the prior art, the connection between the pedal and the rotating shaft is relatively fragile, and the problem of easy deformation occurs. Improve the supporting strength of the balance of the car.
