Technical Field
The invention relates to the technical field of traffic and amusement equipment, in particular to a kart and a control method thereof.
Background
The drift and the drift are originally terms in the field of racing cars, and refer to that a larger included angle is formed between the direction of a head of a car and the actual motion direction of a car body so as to enable the car body to complete series of operations such as lateral sliding, bending and the like, and the condition of the drift is that most or all of the grip force of a rear wheel is lost, and meanwhile, a front wheel can keep a certain grip force, and at the moment, as long as the front wheel is subjected to a certain transverse force, the drift of the car body can be generated. Among leisure and recreation facilities, the kart is a vehicle facility formed by making full use of the drift principle, and is popular among people because of easy driving and safety stimulation. With the continuous development of science and technology, the electric balance car (also called a body sensing car and a thinking car) is used as a novel green and environment-friendly product and has been used as a tool for riding instead of walking and leisure and entertainment by modern people. In order to meet the more deep entertainment requirements and the control experience of people, products which are fused with functions and structures of the traditional electric balance car (especially a double-wheel balance car) and the traditional kart appear at present, and the products basically adopt a rear-driving structural form, namely: the basic structure of the frame is that an assembly space is provided for the electric balance car at the rear end (such as the tail) of the frame or below the seat, and meanwhile, control handles are arranged on two sides (or two sides of the seat) of the space above the electric balance car, and the electric balance car is controlled to steer through the control handles so as to achieve the so-called drifting and drifting effects.
However, because electrodynamic balance car is located the rear end of whole automobile body for the driving point and the bearing point of vehicle have all fallen on the rear side of automobile body, when utilizing to control the handle and carry out steering control to electrodynamic balance car, the rear wheel of automobile body (electrodynamic balance car promptly) can not lose most or all land fertility of grabbing, thereby can't form more obvious automobile body drift phenomenon, promptly: the drift cannot be realized in the true sense, and the drift effect and the user experience effect of the whole vehicle are further reduced. Meanwhile, because the control handles are arranged on two sides of the seat, when a driver holds the operation handles, the arms can only move forwards or backwards in a small distance on two sides of the seat, and the arm placing and moving habits of people in driving a traditional vehicle are not met. In addition, these products have drawbacks such as relatively complex structures, inability to adapt to the individual conditions of the driver, and the like.
Therefore, the product that current balance car and kart combined together has the problem that the drift effect is relatively poor and user experience effect is relatively poor.
