Description

Vehicle body The present invention relates to a vehicle body of an in-wheel platform vehicle in which a high-voltage battery is mounted through a floor member forming the floor of the vehicle and a frame member coupled to the top of the floor member, and a seat is coupled to the top of the frame member. The vehicle body must be designed to accommodate various internal equipment and efficiently absorb impact loads in the event of an impact to protect the occupants. Conventional vehicles require space for the engine or battery, as well as space for the wheels, suspension, and steering systems necessary for propulsion. Consequently, individual wheel housings, suspension systems, steering systems connecting the wheels, and drivetrains transmitting driving force occupy significant space within the vehicle body. Therefore, this must be taken into account during the body design process, and the vehicle must be engineered to absorb impacts. Furthermore, as the number of components to consider increases, the manufacturing and assembly processes become more complex and time-consuming. However, recently, in-wheel systems have been developed in which drive, steering, and deceleration components are integrated into the vehicle's wheels. Since in-wheel systems do not require individual connections to each wheel, unlike conventional vehicles, the vehicle body must also be designed differently. Therefore, when a vehicle adopts an in-wheel system, there is a need to develop a body that allows for the formation of space for each wheel housing, ensures sufficient body rigidity, and further simplifies manufacturing and assembly processes. The matters described above as background technology are intended only to enhance understanding of the background of the present invention and should not be construed as an acknowledgment that they constitute prior art already known to those skilled in the art.

FIG. 2 is a drawing showing a high-voltage battery being mounted in a spaced-out space of a frame member in a vehicle body according to an embodiment of the present invention. A vehicle body according to an embodiment of the present invention includes a floor member (100) provided at the bottom of the vehicle; a support member (210) coupled to the upper surface of the floor member (100); and a frame member (200) coupled to the upper end of the support member (210) to form a spaced-out space between it and the floor member (100), and a high-voltage battery of the vehicle being mounted in the spaced-out space. Additionally, the floor member (100) may be formed in a grid shape, and a plurality of support members (210) may be provided spaced apart, with their lower ends coupled to the upper surface of the floor member (100) and extending upward. The vehicle body according to one embodiment of the present invention is intended for a vehicle using an in-wheel system, unlike conventional vehicles, and there is no need to connect a drive shaft or steering device between each wheel. Accordingly, each vehicle wheel is provided with a shock absorber and a shock absorber housing at the top of the wheel, and the vehicle body is constructed using each truss member to connect each shock absorber housing and simultaneously secure the rigidity of the vehicle body in the event of a vehicle collision. In addition, the vehicle of the in-wheel system is driven using a high-voltage battery, and by mounting the high-voltage battery in the space between the grid-shaped floor member (100) and the seat, it is easy to secure the interior space of the vehicle and p
