A rotatable trailer bed includes a frame, a trailer bed, a turntable swivel assembly, and a plurality of swivel casters. The frame includes a bed section, a hitch section, and two wheel sets. The hitch section is adjacently connected a front end of the bed section. The two wheel sets is rotatably mounted to the bed section. The plurality of swivel casters is mounted to the bed section is perimetrically positioned around the bed section. The trailer bed is rotatably mounted to the bed section through the turntable swivel assembly as the plurality of swivel casters maintain the balance and level of the trailer bed.

A vehicle-body structure improves mounting rigidity of a battery protection frame and rigidity of the battery protection frame itself by including a battery protection frame which has a hollow cross-section, a vehicle-body-side frame which extends along the battery protection frame and is coupled with the battery protection frame, and a fixation member which is inserted through a hole portion of the battery protection frame and is capable of fixing the battery protection frame to a vehicle body component as another component than the vehicle-body-side frame in an internal portion of the battery protection frame.

A vehicle-body front structure includes a partition wall portion which demarcates a space inside a vehicle cabin, a motor arrangement portion which is formed by causing a part of the partition wall portion to bulge to an inside of the vehicle cabin and in which at least a part of a traveling motor is capable of being arranged, a reinforcement member which is inclined to be positioned lower toward vehicle rear, and a floor reinforcement which extends in a vehicle front-rear direction. A closed cross-section is configured with the motor arrangement portion, the reinforcement member, and the floor reinforcement.

A movable object includes: a steering part including a wheel provided to rotate along a ground, a wheel rod connected to the wheel and extending in a direction away from the wheel, and a steering motor connected to the wheel rod to rotate the wheel rod and steer the wheel; and a cover part disposed on top of the steering part, and including a receiving member in which a portion of the steering part is received. When the steering motor rotates the wheel rod in one direction, the steering part is engaged with the receiving member so that the steering part and the cover part may be joined, and when the steering motor rotates the wheel rod in an opposite direction, the steering part is separated from the receiving member so that the steering part and the cover part may be disengaged.

A multipurpose vehicle system with interchangeable operational components and power supplies is operational in multiple operational modes. The operational modes include: a personal transport vehicle mode, a service vehicle mode, and a commercial vehicle mode. The vehicle system has a dimensionally adjustable chassis module. The chassis module has the capacity to detachably attach to multiple exterior, interior, motor, and transmission components. The chassis module supports a cabin module and a rear module that enables formation of different iterations of vehicles. The vehicle system provides multiple different and interchangeable power supplies, like a rechargeable battery and a hydrogen tank. The power supplies are interchangeable. The used components can be recycled and interchanged with new components. The vehicle system also comprises at least one autonomous trailer that comprises a receiver in communication with a transmitter in the chassis module, allowing the autonomous trailer to be remotely towed by the chassis module.

A vehicle with a pod detachably secured to a planar surface chassis thereof, when in hazard escaping or transferring the pod to another platform, a control system will cause the pod to be detached from the chassis, and causing wheels to be moved out of wheel recesses which is disposed partly in the pod, so as to provide some freedom for the pod to be moved laterally, by a side impact, or to enable the pod to be moved on the chassis partly or completely out of the vehicle longitudinally. Thereafter, the control system activates a device for preventing another vehicle from intruding into the space lefy by the moved pod.

An assembly for releasably engaging an upper vehicle part with a base vehicle part comprises the upper vehicle part, the base vehicle part and a securing assembly for ensuring that the upper vehicle part is secured to the base vehicle part in an operational state of the vehicle. The securing assembly comprises an inter-connecting member adapted to extend from the upper vehicle part to the base vehicle part in said operational state, said inter-connecting member having a body portion and a projecting portion defining an abutment surface. The securing assembly further comprises a releasable fixation support having a recess adapted to accommodate a part of the body portion, wherein another part of the releasable fixation support is capable of restricting displacement of said inter-connecting member in a direction towards said upper part vehicle by engaging with said abutment surface of said projecting portion in said operational state.
