Abstract: A magnetic seat adjustment system includes a frame structure, a movable adjustment mechanism, and a control system. The frame structure includes a first magnetic portion fixedly coupled to the frame structure and including first magnetic members that independently generate a magnetic field. The movable adjustment mechanism includes a movable base and a second magnetic portion. The second magnetic portion is fixedly coupled to the movable base and includes second magnetic members that independently generate a magnetic field. The control system controls a change in the magnetic field of the second magnetic members and/or the first magnetic members. When the magnetic field of the second magnetic members interacts with the magnetic field of the first magnetic members, the seat is in a magnetic levitation state, so that movement of the movable base drives movement of the seat.

Abstract: A hardness adjustment unit includes an elastic frame, a barrier, and a field generator. An enclosed space is provided inside the elastic frame and filled with a fluid filling. The barrier is arranged in the enclosed space and divides the enclosed space into an upper space and a lower space. The upper space communicates with the lower space. The field generator is arranged outside the elastic frame and used to apply a field to the fluid filling to adjust a viscosity of the fluid filling, thereby adjusting a flow damping of the fluid filling in the upper space and the lower space to control a deformation of the elastic frame.

Abstract: A modular vehicle body includes a pair of outer frames. An inner board space with a fixed width is defined between the outer frames. Each outer frame includes a front side board and a door sill. The front side board includes a main board provided with a vertical board having a predetermined width. A first flange is provided on a side of the vertical board. The door sill includes an inner board provided with a horizontal board having a predetermined width. A second flange is provided on a side of the horizontal board. The inner board is fixedly coupled to the main board. The first flange and the second flange form an outer edge. A width between the outer edges of the pair of outer frames is set to correspond to a width of a vehicle body.

Abstract: An adjustable seat includes a carrier, a seat body, a first linking rod, a second linking rod, a sliding mechanism, and an adjustment block. The seat body is arranged on the carrier and includes a seat surface switchable between a first direction and a second direction. The first linking rod is hinged to the seat body and the carrier. The second linking rod is hinged to the seat body and the carrier. The sliding mechanism includes a slide rail and a slide block slidably engaged with the slide rail. The slide block is hinged to the seat body. The slide rail is hinged to the first linking rod and the second linking rod. The adjustment block is slidably coupled to the slide rail or the seat body for switching the seat surface between the first orientation and the second orientation.
