Background

The existing skateboard provides power to drive the skateboard to move forward by stepping on the ground, the earliest skateboard for children does not have a handle, because the balance capability of children is poor, the physical strength is small, the balance is not easy to keep in the process of stepping on the ground, the skateboard is easy to fall down, the children are not easy to learn, in order to enable the children to get on the hands more easily, handrails fixed on the skateboard body are additionally arranged on a plurality of current skateboard for children, the existing skateboard for children can only exercise the lower limb strength of the children by stepping on the ground, but the arm strength can not be well exercised by stretching, meanwhile, when the children use the ground for a long time, the legs are easy to fatigue, the children can not travel for a long distance through the scooter, the skateboard can not well become a riding tool for the children when the children go out to walk or walk around with the adults, and the skateboards for a plurality of children need to hold the adults after sliding for a certain distance.

The invention discloses a novel scooter with a patent number of CN02203742.X, the application utilizes a rocker to drive a rack to move in a reciprocating manner, and the left and right clutches with different transmission directions are respectively arranged on the two sides of the rack to realize that the pushing and pulling energy of the rocker can be transmitted to a rear wheel; this patent does not transfer kinetic energy input to the front wheels because it does not address the problem of a single wheel having both manual power input and manual steering. 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 patent application No. CN201821237663.5 discloses a power assisting device for a scooter, which has the technical effects of prolonging the time interval of pedaling the ground, increasing the skating fun, prolonging the fatigue feeling time of the rider, and increasing the coordination ability of the body, especially the coordination ability of hands and feet.

This patent through with speed wrench's switching-over knob through act as go-between with the controlling means on the handle of scooter connect with clutch's act as go-between with the controlling means on the handle of scooter 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 technical scheme operation of this patent protection is very complicated, and is unsuitable children use, especially makes the low age children.

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 the energy of human low limbs.

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.
