The present invention relates to a self-powered drone flying car for land and air, in which a circular riding spherical body () that is a commercial space in which a person rides to fly, steer, and control the flying car is formed, a drone wing device () that is a flying device is mounted onto the riding spherical body, and a ground driving device for driving on the ground is mounted to a lower portion of the riding spherical body, in order to perform both flying in the air and driving on the ground. Also, an intermediate connection attaching and detaching device () is formed between the devices to separate and connect the devices depending on whether the flying device or the ground driving device is necessary.

The present invention relates to an electric kickboard in which an impact absorbing device is installed, and more particularly, to an electric kickboard including an impact absorbing device to support a weight of a user standing up by allowing the impact absorbing device to sufficiently absorb an impact when a seat is vibrated during riding by using elasticity of springs having different spring constants and including a self-power generating drive at one side thereof to produce electricity using vertical vibrations during riding and accumulate the produced electricity, thereby improving an energy efficiency.
