Meanwhile, the scooter is difficult to operate in the using process, when the rocker is manually shaken forwards and backwards, the scooter cannot turn, even if the scooter is forced to turn, the left balance or the right balance of the scooter is broken by pulling the rocker leftwards or rightwards, and the scooter is easy to topple to one side. When the manual power of the scooter is input, the power input can not influence the left-right balance of the scooter only by always keeping the power to be right and back; because the rocker of the patent has the functions of manual force input and steering and the mobility of the rocker needs to be kept, the technical scheme of the patent can only input manual force and cannot switch and input manual force and foot power, so that a manual power input mechanism and steering are difficult to finish by hands, and the biggest problem is that the steering cannot be controlled when power is input, so the front wheel of the existing skateboard can only be used as a steering wheel.

This patent is because the rocker is the automobile body relatively all the time can pivoted, when this patent rocker rotates around, need the health constantly to adjust focus adaptation reaction force, when meetting scram or downhill path and accelerating, children do not have the fixed handle of relative slide body and can rely on, stabilize the focus, finally lead to the health to topple over forward easily or backward under the inertia effect, so the technical scheme of this patent protection is unsuitable in the use of children's life in various living environment, because children slide plate skill is general less strong, so this kind of condition that does not have the object that can rely on keeps balanced leads to children to tumble easily.

The utility model discloses a booster unit of scooter is disclosed to application number CN201821237663.5 utility model, the technical effect who records in the application document of this patent is that can prolong the time with the time interval on foot pedal ground, increases and slides the enjoyment, prolongs the time that the tired sense of emergence of taxier to and increase the coordination ability of health, especially the cooperation ability of trick.

This patent through with speed wrench's switching-over knob through act as go-between with the controlling means on scooter's the handle connect with clutch's act as go-between with controlling means on scooter's the handle connect, in the use, with pedal speed wrench, store kinetic energy in the clockwork spring, through manual control clutch, realize the input and the output of power to realize the cooperation ability of trick, the operation is very complicated, unsuitable children use, especially make young children.

The working process of the patent is as follows (original text): the foot is used for rotating the speed wrench 6, the tooth driven shaft 3 is driven to rotate through the speed wrench 6, the clockwork spring in the clutch device 5 is driven to store energy through the tooth driven shaft 3, after the capacity storage is finished, the pull wire 8 is driven to move through the control device, the clutch block 5-2 is driven to move through the pull wire, the clutch block 5-2 rotates around the mounting shaft 5-5 through the clutch block 5-2, the clutch block 5-2 is meshed with the clutch gear 5-1, the clutch gear 5-1 is fixed, the power of the clockwork spring is prevented from being conveyed to the tooth driven shaft 3, in the sliding process of the scooter, the kinetic energy is transmitted to the gear 2 through the clockwork spring, the kinetic energy is transmitted to the flywheel 1 through the gear 2, and the scooter is driven to advance through the flywheel 1.

This patent is through earlier with pedal speeder wrench, utilize the energy storage device energy storage, the dual power output of kinetic energy through pedal ground and release storage after the kinetic energy storage can prolong the time with the time interval on pedal ground, but can not prolong the time that the person of sliding appears tired sense, because the storage of kinetic energy also needs the human body to do work and accomplishes, because the output and the input of power are equal, slide how far away distance, just need input corresponding power, so this patent can not reach the time that the person of sliding appears tired sense, the kinetic energy of stepping on speeder wrench storage with the foot in advance also need consume human energy.

This patent energy storage device structure is complicated, leads to scooter cost higher. Traditional scooter pedal ground in-process, slide and human can produce very fast initial velocity, and human and slide inertia can store kinetic energy itself, and it can lead to the structure complicacy to increase extra energy storage part, the cost of more increase slide. Meanwhile, the purpose of exercising arm muscles can not be achieved through stretching of arms, power can be provided only by feet, and the problem of contradiction between manual power input and steering is not solved.

When a person walks or runs on a flat ground, the person only needs to move, and the feet and the legs can be loaded and exercised under the action of the gravity of the body, but the arms of the person are difficult to be loaded and exercised in life activities without doing work with high labor intensity, so that the market needs a skateboard capable of exercising the arm strength of children.
