In claim 1, A vehicle body characterized in that a flange protruding outwardly from the closed surface of a roof member is formed on the closed surface of the roof member, and the roof member is joined to an upper truss member through the closed surface and the flange by making surface contact.
  10. In claim 1, A vehicle body characterized in that the roof member has a shape that narrows in width from the end toward the inside, and the vehicle's windshield glass is attached to the front or rear of the roof member.
  11. In claim 1, It further includes a plurality of support members that connect and support the upper truss member and the loop member, and A vehicle body characterized in that one end of the support member is connected to the side of the upper truss member and the other end is connected to the front or rear of the roof member.

Description

Vehicle body The present invention relates to a vehicle body comprising a plurality of shock absorber housings located at the top of each wheel in a vehicle with an in-wheel platform, a plurality of upper truss members connecting each shock absorber housing at the side of the vehicle, and a roof member connecting each upper truss 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. 1 is a drawing showing a roof member being connected to the upper end of an upper truss member in a vehicle body according to one embodiment of the present invention. FIG. 2 is a drawing showing a state in which a roof member is connected between two upper truss members in a vehicle body according to one embodiment of the present invention. FIG. 3 is a drawing showing a state in which a support member supporting a roof member and an upper truss member is combined in a vehicle body according to one embodiment of the present invention. FIG. 1 is a drawing showing a roof member being connected to the upper end of an upper truss member in a vehicle body according to an embodiment of the present invention. FIG. 2 is a drawing showing a state in which a roof member is connected between two upper truss members in a vehicle body according to an embodiment of the present invention. FIG. 3 is a drawing showing a state in which a support member supporting a roof member and an upper truss member is connected in a vehicle body according to an embodiment of the present invention. FIG. 1 is a drawing showing a roof member being connected to the upper end of an upper truss 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 plurality of upper truss members (200) that form both pillars of a vehicle, with one end connected to a front vehicle body and extended upward and bent, and the other end connected to a rear vehicle body; and a roof member (300) that extends in the width direction of the vehicle and has both ends connecting the upper ends of the plurality of upper truss members (200), and the ends of the roof member (300) and the upper end of the upper truss member (200) are connected by sliding in the length direction of the vehicle. The front and rear bodies, to which one end and the other end of the upper truss member (200) are connected, may be a front shock absorber housing (100) and a rear shock absorber housing (100) that cover and support the upper part of the shock absorber connected to the vehicle wheel. The vehicle body according to one embodiment of the present invention is intended for a vehicle using an in-wheel system, unlike a conventional vehicle, 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 (100) at the top of the wheel, and an upper truss member (200) connecting the front and rear body members or the front and rear shock absorber housing (100) is provided on the side of the vehicle to secure the rigidity of the vehicle body, and the upper truss members (200) on both sides are connected by a roof member (300) sliding in the longitudinal direction of the vehicle. Specifically, both upper truss members (200) have their ends connected to the upper surfaces of the front and rear body members or the front and rear shock absorber housings (100), and extend upward
