Abstract: A connection device for charging electric vehicles provides direct electrical connection for an external source of electricity to charge the battery of an electric vehicle. It mainly comprises a movable charging terminal combined with n switch, both located on the body of an electric vehicle. When the charging terminal is moved into a position that enables an electrical connection with an external source of electricity, the switch is automatically moved into a position that cuts off electricity to the driving motor of the electric vehicle, rendering the electric vehicle incapable of being started during electrical charging, thus preventing accidents from occurring.

Abstract: A vehicle frame with replaceable rearward inclined angles for front wheels allows users to alter the rearward inclining angle of the front wheels to form different car styles. The vehicle frame has a separable axle hub. The axle hub is a replaceable element which has apertures of different rearward inclined angles to selectively engage with the frame such that the front wheels may be inclined rearward at different angles to form different car styles.
