Abstract: An electronic accelerator of a motorized vehicle includes a shield mounted between a light sensitive resistor and a focusing type LED. The amount of the light source received by the light sensitive resistor from the focusing type LED can be converted into different signals, so as to control the rotational speed of the motor. The shield may be applied to the accelerator of a vehicle, including the accelerating handle, the accelerating pedal, or the accelerating lever. When the accelerator drives the shield to rotate, the arc-shaped surface secured on the shield has a shielding area gradually reduced from one side to the other side, thereby allowing the focusing type LED has a greater amount of light source to be emitted on the light sensitive resistor, thereby preventing the electronic elements from wearing due to friction during operation.

Abstract: A drive device of a motorized scooter primarily includes a horizontal connecting plate and a vertical connecting plate mounted on a frame of the scooter and defining a horizontal connecting hole and a vertical connecting hole. The horizontal connecting hole and the vertical connecting hole are pivoted to the axial hole and the radial threaded hole of the wheel seat. The horizontal connecting hole and the vertical connecting hole have a slightly greater diameter, so that the wheel seat may deflect horizontally and vertically. The wheel seat is respectively pivoted with two wheel covers by a pin and a torsion spring. The front wheel cover in contact with the wheels to provide a brake effect. The inside of the rear wheel cover is secured with a motor whose two ends are fitted with a drive wheel to contact and drive the wheels.

Abstract: A transmission structure of a gearbox of an electrically actuated car includes two front wheels, two rear wheels, and two gearboxes, wherein one gearbox is mounted between the two front wheels, and the other gearbox is mounted between the rear wheels. The transmission structure also comprises a motor mounted between the two gearboxes. The motor has a power shaft having two distal ends each connected to a differential gear of each of the two gearboxes by means of a coupler, so as to form a four-wheel transmission mechanism.
