BODY STRUCTURE


  1. CONSTRUCTION


    1. Body Shell


      1. The position of the body's structural parts is optimized and reinforcing materials are provided, creating a body structure with high rigidity and ensuring driving stability.


        • A straight ladder structure that passes through the floor side members from the rear portion of the dash panel to the rear portion of the rear wheel house is used to ensure torsional rigidity of the floor.

        • The area around the corners of the door opening uses the following optimal structures, ensuring rigidity of the sliding door opening.


          • The center body pillar reinforcement UPR (*1 in illustration) and center body pillar inner UPR (*2 in illustration) are extended to the corners, restraining cross-sectional collapse.

          • The ridge lines of the reinforcements run through the T-shaped section, suppressing cross sectional collapse.

          • The side panel outer (*4 in illustration) and rocker panel reinforcement No. 3 (*5 in illustration) are connected, restraining cross-sectional collapse.

          • The lower portion of the quarter lock pillar lower outer (*6 in illustration) and lower portion of the side panel outer (*4 in illustration) are spot welded together, and the No. 3 lower rail plate inner (*7 in illustration) is spot welded to the quarter wheel house panel outer (*8 in illustration) and roof side panel inner lower (*9 in illustration). This prevents bending deformation vertically throughout the quarter lock pillar.

    2. Spot Welding


      1. An increased number of spot welding points are provided throughout the body, increasing the connectivity of the panels and ensuring superior driving stability (steering response and hand feedback).


        • Numerous spot welding points are concentrated in areas that will effectively increase body rigidity such as the floor member and the connecting portion of the dash panel and cowl top inner panel to ensure superior riding comfort.

    3. Lightweight Solution


      1. The structure and materials of the body have been optimized, achieving a lightweight body and ensuring driving stability.


        • The drive method of the electric sliding door uses a position in the step (belt drive (*6 in illustration)). Also, the lower rail (*b in illustration) and motor unit bracket (power slide doorstep assembly: *5 in illustration) are made of resin and integrated with the slide door motor unit (*1 in illustration), reducing the weight of the drive unit of the electric sliding door.

        • Roof beads (*a in illustration) are provided in the roof panel (*1 in illustration), and reinforcements are optimally positioned to achieve roof panel (*1 in illustration) weight reduction while also ensuring rigidity strength. Also, for models with a normal roof, the positions of the roof beads are split, reducing muffled sounds that come from the roof panel (*1 in illustration).
