Abstract: An electric vehicle includes a chassis and a seat assembly that includes a plurality of seats mounted to the chassis. The chassis includes a vehicle frame defining a mounting space, and a battery module disposed in the mounting space and including an outer battery unit that is mounted to the vehicle frame, and an inner battery unit that is coupled to the outer battery unit. The vehicle frame is operable to switch between an expanded state, where the inner battery unit is permitted to be coupled to the outer battery unit and the seats are spaced apart from each other, and a collapsed state, where the inner battery unit is prevented from being coupled to the outer battery unit and the seats are overlapped with each other.

Abstract: A resilient power device is adapted to drive a transmission rod of a vehicle, and includes a housing, a rotary shaft adapted to extend and be spaced apart from the transmission rod along a first axis, a power release unit including a first rod and a second rod that extend and are spaced apart from each other along a second axis parallel to the first axis, a power storage clutch adapted to be connected between the transmission rod and the rotary shaft, a power release clutch connected between the first and second rods, a first gear unit mounted to the first rod and the transmission rod, a second gear unit mounted to the rotary shaft and said second rod, and at least one resilient member connected between the housing and the rotary shaft.

Abstract: A modular electric vehicle includes a first body module having a lateral connecting side, a second body module having a lateral connecting side, two first wheels mounted to the first body module, two second wheels mounted to the second body module, and a connection unit. The connection unit includes a first electrical connector disposed at the lateral connecting side of the first body module, and a second electrical connector disposed at the lateral connecting side of the second body module. The first electrical connector is operable to be selectively and electrically coupled to the second electrical connector, so that the first and second body modules can be selectively assembled to form a relatively light electric vehicle.
