[Industrial applications]

 The present invention relates to a children's electric vehicle for children to drive and play.

[0002]

[Prior art and its problems]

 The electric vehicles currently on the market that are operated and operated by children do not have a separate control device, so full control of the electric vehicles is left to young children. However, it is not possible for young children to judge whether or not they are in danger because their judgments are immature. Therefore, when operating an electric vehicle, the electric vehicle often collides with a wall at the limit of the space used, and the electric vehicle loses its way forward or backward, and the infant cannot immediately change the direction in which the electric vehicle moves forward or backward. In this case, the electric vehicle drive motor will not be able to rotate under energized conditions and will eventually result in damage to the drive motor. Furthermore, the electric vehicle may not only hit the wall, but also the furniture. In this case, there is a risk that the articles placed on the furniture will fall and directly injure the child.

Furthermore, if the electric vehicle is run to a stepped place under the condition that the child does not know, the child and the electric vehicle will fall down the stairs, which may directly hinder the child. become. Adults usually watch outside the range of action of an electric vehicle in order to allow adults to enjoy driving the electric vehicle as much as they want, and thus they may be separated from the electric vehicle by a certain distance. However, the danger is instantaneous and it is impossible for an adult to save it and eliminate the danger in a short time. For this reason, it is an urgent task at this time to design and install a controller that protects the safety of children in electric vehicles so that children can fully enjoy themselves.
