Purpose-built vehicle
A purpose-built vehicle includes a windshield selectively presenting an image toward the inside and the outside of a vehicle, and a seat, a position of the seat being movable inside of the vehicle and a seating base of the seat being attachable and detachable. Particularly, the seating base of the seat is configured to have such a rotatable structure that the seating is detached from a frame of the seat and then is possibly fitted in place in an arbitrary space.
1 . A purpose-built vehicle (PBV) comprising:
a windshield selectively presenting an image toward the inside and the outside of a vehicle; and
a seat, a position of the seat being movable inside of the vehicle and a seating base of the seat being attachable and detachable;
wherein the seating base of the seat is configured to be detachable from a frame of the seat and then fitted in place in an arbitrary space,
wherein an upper end surface of the seating base has such a curved structure that the upper end surface thereof is increasingly inclined upward toward the front, and a lateral surface of the seating base is configured to have such a curved structure that the lateral surface thereof is increasingly expanded outward toward a downward direction in order for a user's calves to rest on the lateral surface thereof.
2 . The purpose-built vehicle of claim 1 , wherein the seating base is made of high-rigidity carbon fiber reinforced plastic (CFRP).
3 . The purpose-built vehicle of claim 1 , wherein the seating base is configured to have such an integrated structure that three surfaces thereof are connected to each other.
4 . The purpose-built vehicle of claim 1 , wherein the seating base has such a fitting structure that seating on the seating base is possible by rotating supports that are capable of supporting at least two surfaces of the seating base, respectively.
5 . The purpose-built vehicle of claim 1 , wherein the seating base comprises:
supports connected to both lateral surfaces, respectively, of the seating base in such a manner that the supports are rotatable with respect thereto;
a hinge shaft rotatably connecting the supports to the both lateral surfaces, respectively, of the seating base; and
fixation portions positioned on respective sections, respectively, of lateral end portions of the seating base in such a manner that the supports maintain rigidities thereof in a state of being rotated outward.
6 . The purpose-built vehicle of claim 1 , wherein the windshield comprises:
an electrochromic image region, shading of the electrochromic image region being adjustable in such a manner that, according to application of electric power, an image is selectively presented toward the inside and the outside of the vehicle; and
a non-transparent image region extending from a lower end of the electrochromic image region.
7 . The purpose-built vehicle of claim 1 , wherein the windshield is divided into an internal display region presenting the image toward the inside of the vehicle and an external display region presenting the image toward the outside of the vehicle.
8 . The purpose-built vehicle of claim 7 , wherein the internal display region and the external display region have respective electricity application paths that are separated from each other.
9 . The purpose-built vehicle of claim 1 , wherein, when the seating base is detached from the frame, the seating base comprises supports rotatable with respect to both lateral surfaces, a hinge shaft rotatably connecting the supports to the lateral surfaces of the seating base, and fixation portions that keep the supports fitted in place in a state of being rotated outward to form a three- or four-point support.
