The mode of riding of the electric motor car after the combination except that expand and ride, also can ride after folding, the mode of riding of electric motor car after folding is:

controlling the foldable electric vehicle to move straight:

when the carrier platform 300 is folded with respect to the lever 400, the rider stands on the pedals of the balance car and holds the lever to ride, as shown in fig. 14, while driving the car. The forward or backward movement is controlled by the foot force (driving the operating lever or stepping on the foot pedal of the balance car) or by the hand force to control the operating lever, so that the balance car 100 tilts forward or backward. When the operation rod is used for controlling the vehicle to move forwards or backwards, the forward tilting or backward tilting of the operation rod drives the balance vehicle to move forwards or backwards so as to accelerate or decelerate.

Controlling the steering of the foldable electric vehicle:

the steering of the vehicle is realized by twisting the operating rod 400, and the left and right twisting of the operating rod drives the vehicle to turn left or right. Of course, when the foot force is used for controlling the vehicle to move forwards or backwards, the feet of a user stand on the two pedals of the balance vehicle to control the vehicle to move forwards, backwards, accelerate, decelerate or turn.

The riding operation mode of the electric vehicle in the unfolding state is as follows:

when the electric vehicle is a scooter: the electric motor car is in the expansion state, and the car adopts the scooter load-bearing platform, does not install seat 600 (or installs higher seat) on the load-bearing platform promptly, and the electric motor car after the combination this moment is electric scooter, and personnel are in stand or sit the seat and step on the state on load-bearing platform, and the advancing or retreating is through action bars 400 control, and the left and right sides is rotated and is passed through action bars drive balance car 100 and turn.

The riding mode is that besides riding when a person stands on the scooter bearing platform, a seat 600 can be added on the scooter bearing platform, the person sits on the seat, two feet step on pedals of the balance car, the front and back inclination of the balance car is controlled by the two feet to control the forward and backward movement, the body of the balance car is rotated by the two feet to realize turning, or the person sits on the seat, the two feet are placed on the bearing platform 300, the front and back inclination of the balance car is controlled by the operating rod 400 to control the forward and backward movement, and the body of the balance car is rotated by the rotation of the operating rod to realize turning; by combining the balance car with the scooter frame, the functions of the balance car 100 are expanded, and the use function and the safety of the balance car are expanded; the operation rod 400 is used for controlling the running of the vehicle, the operation is convenient, the speed and the direction of the hand-operated operation rod are controlled, and the operation is simpler and more convenient.

When the electric vehicle is a carting car: the electric vehicle is in an unfolded state, the electric vehicle adopts a kart bearing platform, namely a seat 600 is arranged on the bearing platform, the electric kart is adopted, when a person sits on the seat and feet are placed on pedals of the balance car or on two sides of an operating rod, the forward movement, the backward movement and the turning are preferably controlled through the operating rod 400, the operation is simple and convenient, and the riding is comfortable; the forward, backward and left-right rotation can also be controlled by the two foot pedals of the user stepping on the two foot pedals of the balance car 100, and the operation principle is the same as that when the carrying platform is folded relative to the operating rod, the car is controlled by the two feet of the user to run.

Through balance car and kart frame combination, the expanded balance car function has expanded the service function and the security of balance car 100, and the both sides of action bars 400 bottom can set up puts the foot for put the foot.

The design concept of the invention is as follows: the balance car and the scooter or the balance car and the kart are combined to form a product with new functions, and free conversion between the balance car and an electric vehicle (the scooter or the kart) is realized. Realize through combination, the split with the balance car with corresponding function electric motor car frame, the electric motor car after the combination has electric scooter or kart's safety, practical characteristic, but the balance car normal use behind the split to change the operation mode of traditional electric scooter or kart, use action bars 400 to accomplish the operation with higher speed, slow down, advance, move back, turn, have higher object for appreciation nature.

The specific operation principle is mainly based on the basic principle of the balance car.

When accelerating, advancing, adopt and push forward certain angle with the action bars, at this moment, the action bars drives balance car automobile body and inclines forward, and the gyroscope can sense inclination in the automobile body, feeds back the control panel as controlling means, and the in-wheel motor that the control panel control is as drive arrangement accelerates, and the principle of slowing down is the same.

When turning, the operation rod 400 drives the balance car 100 to turn left or right integrally, thus realizing turning.

In order to realize flexible control of the operating rod, the rotating connection arrangement between the operating rod and the bearing platform needs to be realized in a matching way.

Specifically, fix the scooter frame on the balance car through fixed subassembly 201, the scooter frame has the swing joint relation (fore-and-aft direction and left and right direction respectively) on two dimensions with fixed subassembly at least, action bars and fixed subassembly or through support and fixed subassembly fixed connection.
