Description

Vehicle body The present invention relates to a vehicle body comprising a plurality of shock absorber housings located on the upper part of each wheel in a vehicle with an in-wheel platform, wherein the shock absorber housings cover and support shock absorbers connected to the vehicle wheels. 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.
