Description

Safety remote electric child car improved chassis structure

But the utility model is the improvement about a kind of safety remote control formula seat children's electric motor vehicle chassis structure.

As shown in Figure 1 be the play three-dimensional views of car of existing children, the car of playing of the children among the figure is to adopt the foot-operated type of drive of child, when becoming an electric motor car as upgrading, must be improved on the chassis of playing again.Right this kind of child car of playing is fully at driving with bicycle and with the mode of chain drive in initial design, after being removed on the vehicle frame as with people's force transmission mechanism, need mix some basic modules in order to taking up its circuit loop and important attached safety device, the more important thing is and the circuit loop distribution will be hidden, so can make electric motor car assembling easily, good looking appearance and be difficult for wrecking.Moreover the bearing substrate that has many welderings to establish on the existing vehicle frame, used screw or the open-work position of the load module of each substrate on it, when being drilled with on each substrate, even a little mismachining tolerance is arranged, add the error of substrate position when being welded on the vehicle frame, often make the assembly that is assemblied on the substrate when assembling, the position can't cooperate accurately, and during assembly fee, be not easy, this is the play significant drawback of car of existing children.

In addition, the early stage children car of playing is necessary to be modified to children's electric motor vehicle, be because of the existing foot-operated child car that drives, its ownership is on top of the child, the adult can't adopt indirect intervention, child only can guard the emperor on the car next door, therefore the child relatively can not play to one's heart's content, and the adult can be very arduous, so want the child is driven freely, just must leave carriage for children one segment distance, and can only check child's dangerous play with sound, yet dangerous the adult can't prevent rapidly usually at once normally in the thing that promptly takes place in a flash, and danger situation or unexpected thing condition are promptly usually taken place.If carriage for children is to adopt on electronic form and the car to add a little safety controls, and control with the safety remote control mode and can change the driving direction that the child takes children's electric motor vehicle rapidly, avoid driving towards deathtrap (such as staircase or grounding aluminium door and window large glass etc.) and bump article on every side, the damage of dropping of situation that CD-ROM drive motor burns or article can take place and injure the situation of children own and all can prevent immediately in CD-ROM drive motor running over load at any time in the electric motor car of bump back.

But the purpose of this utility model is to provide a kind of safety remote control formula seat children's electric motor vehicle chassis structure improvement.It is but that the override type children car of playing is modified to safety remote control formula seat children's electric motor vehicle, wherein on the electric motor car hind axle, install a driver by the electro-motor drive, and establish a butterfly substrate in the weldering of vehicle frame tail end below and settle seat, in vehicle frame central authorities below one bow type pedestal is set in addition, can install a charging socket in this pedestal, circuit layout and reception antenna access hole, storage battery, safety remote control device and safety governor, the storage battery supporting part upper limb front and back end of pedestal thus again, set up the other pedal support of stretching, these support two ends can supply sheathed pedal, fix it with the Spring clip clip again, step on sheet by the firing switch on two pedals, the console switch control cabinet that brake switch is stepped on sheet and is located in vehicle frame central authorities top constitutes distance type and takes advantage of the virgin electric motor car of seat, make children can drive electric motor car easily, then can utilize safety remote control device in the hand to match and then intervene the direct of travel of controlling electric motor car as for the adult with safety governor in the electric motor car, avoid children to sail it into dangerous area because of misoperation, thus the generation of the incident of injury can prevent the child seats electric motor car time.
