[0046] Figure 1 It is a view showing a state where two seat frame members of a vehicle body are combined according to an embodiment of the present invention. Figure 2 It is a view showing a state where a floor portion of a vehicle body and a seat frame member are combined according to an embodiment of the present invention. Figure 3 It is a view showing a body frame of a vehicle body according to an embodiment of the present invention, in which a main roof member of the vehicle body constitutes the body frame and a side portion of the seat frame member forms a vehicle pillar. Figure 4 It is a view showing a completed state of a vehicle body according to an embodiment of the present invention. The vehicle body according to the present invention includes: a floor portion 100 provided with a driving portion of the vehicle; and a seat frame member 200 on which a vehicle seat is installed, and selectively combined with a plurality of positions on the floor portion to constitute the vehicle body, so as to perform seat installation and body configuration simultaneously. Among them, the driving portion is a device for driving the vehicle, and is a concept including a motor or an engine, driving wheels, etc.

[0047] In addition, a lower end portion of the seat frame member 200 can be combined with a plurality of positions on the floor portion 100 to form an annular body member, and the annular body member is provided along the width direction of the vehicle, so that a side portion forms a vehicle pillar, and the vehicle seat can be installed inside the annular body member.

[0048] In order to manufacture various types of vehicles optimized for various purposes, in the context of the introduction of a skateboard platform along with the electrification of vehicles, in the body of the present invention, in order to maintain the body rigidity of the skateboard-type floor and ensure collision stability, a circular seat frame member 200 is arranged in the width direction on the floor portion 100 of the vehicle to enhance the side rigidity, and the side portion of the circular seat frame member 200 functions as a pillar of the existing body. Therefore, while ensuring the rigidity of the body, the design and production process of the vehicle can be simplified by using the fewest components.

[0049] In addition, since the body frame is formed by the combination of the skateboard-type floor portion 100 and the seat frame member 200, when more seat frame members 200 are needed or seat frame members 200 are not needed in the floor portion 100, the seat frame member 200 can be conveniently additionally installed or removed. And by lengthening or shortening the length of the floor portion 100 and adding or removing the seat frame members 200 installed on the floor, various vehicles can be conveniently designed and produced according to the purpose. That is, according to the body concept of the present invention, vehicles from small cars to large passenger vans or special-purpose vehicles can be easily manufactured.

[0050] On the other hand, in the body of the vehicle according to the present invention, the seat cushion 210 of the seat is arranged at the lower part inside the seat frame member 200, and the seat back 220 is connected to the rear of the seat cushion, so that when a passenger sits on the seat, the passenger is surrounded by the seat frame member 200. Since the seat is arranged inside such a circular seat frame member, the seat can be installed on the vehicle body without the existing cross beam for installing the seat, thus simplifying the production process. In other words, from the perspective of the production process, after receiving the floor portion 100 and the seat frame member 200 supplied by the supplier and fastening them with bolts or the like, the body can be assembled, so that the vehicle can be manufactured using a smart factory instead of producing the vehicle by welding or painting each vehicle in an existing factory.

[0051] In addition, the body of the vehicle according to the present invention further includes a main roof member 205 arranged along the length direction of the vehicle, and the main roof member 205 constitutes the body frame and can be combined at the position between the upper ends of a plurality of seat frame members 200. Specifically, the main roof member 205 is arranged in the center of the vehicle along the length direction of the vehicle to form the body frame, and when two or more seat frame members 200 are provided, the main roof member 205 is located between the seat frame members 200 and combined with each seat frame member 200. With the setting of the main roof member 205, the overall rigidity of the vehicle increases. In particular, the front and rear rigidity and collision stability of the body are greatly improved, and the side surface of the seat frame member 200 whose lower end is combined with the floor portion 100 is also fixed, so that the front and rear rigidity of the seat can be enhanced.

[0052] In other words, as shown in the figure, the main roof member 205 extends substantially in the longitudinal direction of the vehicle on the roof, and the front end and the rear end of the main roof member 205 are bent downward and joined to the front end and the rear end of the floor portion 100, thereby increasing the collision rigidity at the front and the rear of the vehicle. Further, by joining to the position between the upper ends of a pair of seat frame members 200, the lower end of the seat frame member 200 is fixed to the floor portion 100 and the upper end is fixed to the main roof member 205, whereby the upper and lower ends are fixed together to ensure higher rigidity. Additionally, for the roof, the main roof member 205 and the seat frame member 200 form a lattice-shaped member, thereby also improving the overall torsional rigidity of the vehicle.

[0053] On the other hand, in the vehicle body, the seat frame member 200 may be provided with a display 230, and the angle of the display 230 may vary according to whether the seat is occupied or the tilt angle. Also, the display 230 provided on the seat frame member 200 may be taken out or stored according to the needs of the passenger. Therefore, the passenger can comfortably use the display 230 in various postures, and when the display 230 is not in use, the display can be stored in a hidden manner to move freely in the seat.

[0054] In addition, in the vehicle body, a separate air-conditioning duct 240 may be provided on the inner side surface of the seat frame member 200, so that air conditioning can be performed toward the passenger sitting on the seat, and a separate air-conditioning duct 240 is provided along the annular body member on the seat frame member 200, so that air conditioning can be performed in multiple directions toward the passenger sitting on the seat. For example, when the separate air-conditioning duct 240 is provided on the inner side surface of the seat frame member 200, the passenger can be surrounded inside the seat frame member 200 and air conditioning can be performed toward the passenger. Therefore, compared with performing air conditioning toward the passenger outside the seat frame member 200, the desired air-conditioning performance can be achieved more quickly, and air conditioning can be controlled individually in each seat frame member 200. Also, even if unnecessary air conditioning is not performed on the entire space of the vehicle, the passenger can feel sufficiently comfortable, which is also effective from an energy perspective. Additionally, when the separate air-conditioning duct 240 is provided along the annular body member of the seat frame member 200, compared with when the separate air-conditioning duct 240 is provided on the inner side surface of the seat frame member 200, air conditioning in multiple directions can be achieved, so that faster air conditioning can be realized, and the air circulates in the annular seat frame member 200, thereby enabling individual and more effective control of air conditioning in each seat frame member 200.

[0055] Figure 5 It is a view showing a side storage space provided on the side surface of a seat frame member according to an embodiment of the present invention.Figure 6 It is a view showing a side partition provided between left and right seat frame members according to an embodiment of the present invention. In the vehicle body according to the present invention, a side storage space 250 that can be selectively exposed may be provided on the left or right side of the seat frame member 200. Therefore, when necessary, the passenger can pull out the side storage space 250 forward to store personal belongings, and after storage, the side storage space 250 can be retracted again to ensure the side space and move comfortably.

[0056] On the other hand, in the vehicle body according to the present invention, the sides of a plurality of seat frame members 200 are connected to each other and arranged along the width direction of the vehicle, and a selectively exposed side partition 260 may be provided at a position between each seat frame member. For example, when the side partition 260 protrudes, the left and right seats can be separated in the vehicle to provide an independent space for the passengers, and when there are fellow passengers, the side partition 260 can also be retracted to share the space between the left and right passengers. In addition, with the commercialization of public transportation in the future, it is predicted that many people will use a means of transportation together. In this case, the need for independent space will increase. Therefore, the utilization rate of the vehicle body according to the present invention will be further improved. And when two seat frame members 200 are arranged side by side, the seat frame members 200 on both sides respectively constitute the side columns of the vehicle, and the two seat frame members 200 inside are combined in a manner that they are in contact with each other, so that the side rigidity of the entire vehicle can be maintained.

[0057] Figure 7 It is a view showing an auxiliary frame with an auxiliary partition installed between front and rear seat frame members according to an embodiment of the present invention, Figure 8 It is a view showing that the upper plate of the auxiliary partition serves as a table according to an embodiment of the present invention, Figure 9 It is a view showing that the lower plate of the auxiliary partition serves as an auxiliary seat. In the vehicle body according to the present invention, at a position spaced apart from the front or rear of the seat frame member 200, an auxiliary frame 300 whose lower end is coupled to the floor portion 100 and constitutes the vehicle body together with the seat frame member may be provided. In addition, in the auxiliary frame 300, auxiliary partitions 310, 320 whose edges are coupled to the auxiliary frame to shield the front or rear of the seat frame member may be provided, and the auxiliary partitions may be composed of an upper plate 310 and a lower plate 320. The purpose is the same as the content described above. Not only can the left and right seat spaces be separated by the side partition 260, but also the front and rear seat spaces can be separated by the auxiliary partitions 310, 320 provided in the auxiliary frame 300, so that a completely independent seat space can be provided for the passengers when necessary.

[0058] On the other hand, when the upper plate 310 of the auxiliary partition rotates to the horizontal direction, it can be used as a table. When the lower plate 320 of the auxiliary partition rotates to the horizontal direction in the state where the upper plate 310 does not rotate, it can be used as the seat cushion of the auxiliary seat, and the non-rotated upper plate 310 can be used as the seat back of the auxiliary seat. Since the auxiliary partition is composed of the upper plate 310 and the lower plate 320, in addition to the function of separating the front and rear seats, in front of the seat, the upper plate 310 and the lower plate 320 can be used as a table and an auxiliary seat to facilitate passengers. In addition, when the auxiliary partition is composed of multiple layers of partitions, even at any one seat, when the upper plate 310 or the lower plate 320 is used as a table or an auxiliary seat, the function of shielding the front and rear can be maintained.

[0059] Figure 10 FIG. is a view showing a state in which the main door and the sub-door are opened according to an embodiment of the present invention. In the vehicle body of the vehicle according to the present invention, a plurality of seat frame members 200 are provided at intervals in the longitudinal direction of the vehicle, and a main door 400 is provided on the side between each seat frame member 200 so that passengers can get on and off through the main door 400. The main door 400 can be opened and closed in a BUTTERFLY, SLIDING, etc. manner, and each seat frame member 200 is provided with a separate main door 400 so that passengers in each seat can independently get on and off through the separate main door 400. In addition, a sub-door 500 that opens and closes facing the seat frame member 200 is provided at the front or rear of the vehicle. Items can be loaded or unloaded through the sub-door 500, and in an emergency, passengers can get on and off through the sub-door 500. The sub-door 500 can be opened and closed in a FLIP-UP manner, and passengers can open it from the outside before boarding to store luggage in the space between the sub-door 500 and the seat frame member 200. In addition, although the size of the sub-door 500 is smaller than that of the main door 400, due to the structure of opening and closing facing the seat frame member 200, it has the advantage that passengers can get on and off through the sub-door 400 in an emergency such as when they cannot get on and off through the main door 400.

[0060] On the other hand, in front of or behind the vehicle, between the sub-doors 400 facing the seat frame member 200, there may be a small space facing the side storage space 250 of the seat frame member 200. In this space, a small storage space that can be opened and closed from the outside can also be provided to store personal items or necessary items such as a first aid kit and a personal mobile device provided by the vehicle itself.

[0061] Figure 11 FIG. is a view showing a process in which a sensor is taken out of a sensor housing and operated according to an embodiment of the present invention, Figure 12It is a diagram showing the process of cleaning a sensor in a sensor housing according to an embodiment of the present invention. In the vehicle body of a vehicle according to the present invention, the vehicle is an autonomous vehicle, a sensor housing is provided at the upper end of the vehicle body, and sensors for autonomous driving can be taken out from the sensor housing and operated. In the future, with the commercialization of autonomous vehicles, space for installing various sensors for autonomous driving will be required in the vehicle body. Therefore, in the vehicle body according to the present invention, a sensor housing 600 can be provided at the upper end of the vehicle body, and the sensor 610 is housed in the sensor housing 600. When necessary, the sensor can be taken out and operated by means of POP-UP driving or the like. Such a sensor 610 can be applied to various sensors such as cameras, radars, lidars, etc.

[0062] In addition, the sensor housing 600 can be located at the upper end of the vehicle, specifically, inside the upper end of the main roof member 205. When the sensor housing 600 is located on the main roof member 205 of the frame constituting the vehicle body, the sensor housing 600 can be fixed more firmly compared to setting the sensor housing 600 separately at the upper end of the vehicle body. From the perspectives of rigidity, durability, and stability, it is more beneficial to protect the sensor 610.

[0063] On the other hand, in the vehicle body, a spraying portion 620 and a cleaning portion 630 are provided on the inner side surface of the sensor housing 600. When the sensor 610 is inside the sensor housing 600, cleaning liquid is sprayed from the spraying portion 620. When the sensor 610 is taken out from the sensor housing 600, the cleaning portion 630 can remove contaminants on the surface of the sensor. In autonomous driving, the sensors 610 required for autonomous driving are very important components. However, when the sensors 610 are contaminated by the external environment, they may not work properly or malfunction. To prevent this situation and solve the problem, a cleaning system for the sensors 610 is necessarily required. Therefore, the vehicle body according to the present invention has a sensor 610 cleaning system. Before the autonomous vehicle departs or when the sensors 610 are contaminated by the external environment, the sensors 610 are temporarily housed inside the sensor housing 600, and cleaning liquid is sprayed from the spraying portion 620 inside the sensor housing 600 towards the sensors 610. When the sensors 610 are taken out again, the surface of the sensors 610 is wiped using the cleaning portion 630 located at the upper end of the sensor housing 600. Through this process, the autonomous vehicle can always keep the sensors 610 clean, so that data can be smoothly provided to the vehicle during autonomous driving, and malfunctions of the sensors 610 can be prevented.

[0064] Although the present invention has been shown and described with reference to particular embodiments thereof, it will be apparent to those skilled in the art that various modifications and changes can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
