Intelligence stationary bike for children operation logic mainly is the crank connecting link principle.It holds up control wheel by people's both hands, do (about 15 °～20 ° of positive anticlockwise direction swings, power is reached an eccentric stent (crank) by the control wheel axle, establish a pair of driving wheel at the eccentric stent other end, the snakelike track of a pair of active crop rotation is travelled forward, because people's deadweight has certain pressure and friction to ground, having the crank effect to drive car drives, add the inertia (rear axle is a little more than front-wheel) of a pair of follower, it is moving only control wheel not to be stopped, and car just can ceaselessly move.The car principle that falls back is rotated 180 ° of moving can falling back of not stopping with control wheel, and speed can reach speed of advance.

Everyone uses the suitable intelligent bodily form more than three years old of intelligence stationary bike for children normally, causes people's interest with the entertaining of playing, and reaches the purpose of body-building in the motion that is at play.Because this body-building vehicle has cooresponding alerting ability, can improve children's thinking reaction intelligence in the process that is at play.Because of of the motion of this car, can play the purpose of body-building simultaneously by the people.When the operation body-building vehicle, the people is sitting on the cushion of car, the both sides that are placed on joystick of bipod nature, and hand-held control wheel is done about 15 °～20 ° positive anticlockwise direction swings, and car just can be stopped transport moving again, has tempered both arms and shoulder mortar, waist psoas unawares.In high-rise house, need only in the level land that is being not less than 2 sq ms and just can carry out multiple orbiting motion easily.This car is done power without power supply and other propulsions source and can be driven by people's two hands nature action, compact conformation, firm, easy to use safety, the operator only need look the arrow on the control wheel, the direction of arrow indication is exactly the car sense of motion, can advance, retreat, left, to the right, can do 360 ° rotation in the original place, can also climb and be not more than 7 ° the gradient, can arbitrarily handle and play.

The utility model is described in further detail below with reference to accompanying drawing.
